Dat is gelukt, ondertussen leven we in België allemaal in grote luxe. Hoeveel stakers bezitten een eigen huis, eigen wagen, laptop, flatscreen TV, smartphone en hebben nog geld over voor een reis?<br /><br />Met de bedrijven gaat het minder goed. Het is crisis en de concurrentie uit het Oostblok en uit Azie is moordend. Het laatste wat een bedrijf vandaag nodig heeft, zijn stakers. Staken kost geld, en de winstmarges van de industrie zijn al lang niet meer wat ze vroeger waren. Als ge frustraties hebt met de banken, ga dan naar een andere bank. Er zijn voldoende kleine banken die niet gokken op de financiële markten. Maar werk uw frustraties niet uit op onze bedrijven aub.<br /><br /><br />Maandag wordt er niet gestaakt voor mensenrechten, wel om invloed uit te oefenen op de regering. De vakbonden willen het beleid van dit land bepalen. Als ze het dan toch zoveel beter weten, dat ze dan een partij oprichten. Eigenlijk zou Di Rupo en zijn regering maandag ontslag moeten nemen en tegen de vakbonden zeggen "Doen jullie het maar, en neem ineens het parlement (of alle parlementen sic) over!".<br /><br />We hebben in dit land teveel! Teveel parlementen ok, maar vooral ook teveel luxe. Vergelijk met Azie, het Oostblok, Noord-Afrika waar men nog volop moet zorgen voor basis produkten zoals riolering, electriciteit, proper water enzovoorts. Daar zijn nog veel mensen die willen werken, die hard willen werken en die blij zijn dat ze werk hebben. Wees dus niet boos als na de staking van maandag blijkt dat bedrijven liever in Azie een filiaal openen dan hier.<br /><br />Ik ga werken op maandag, want staken heeft alleen maar nadelen voor ons land!<br /><br /><br /><br /><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-6987038370567944695?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com1tag:blogger.com,1999:blog-18697195.post-22054987892862429952011-11-24T12:16:00.001+01:002011-11-24T12:22:00.887+01:00Today is my 42nd day as a <a href="http://mobilevikings.com/">Mobile Viking</a>.

You should see this:<br /><pre>root@debby6:/etc/iet# cat /proc/net/iet/session<br />tid:1 name:iqn.2010-02.be.linux-training:storage.lun1</pre><b><u>The iSCSI Initiator</u></b><br /><br />The host that connects to this target server is called the <b>Initiator</b>. Most Linux distros have this available as <b>open-iscsi</b>.<br /><pre>aptitude install open-iscsi</pre><br />A discovery will show available devices on the target:<br /><pre>root@ubu1104:/etc/iscsi# iscsiadm -m discovery -t st -p debby6<br />192.168.1.31:3260,1 iqn.2010-02.be.linux-training:storage.lun2</pre><br />Configuration with chap user and password takes a couple of commands:<br /><pre>root@ubu1104:/etc/iscsi# iscsiadm -m node --targetname "iqn.2010-02.be.linux-training:storage.lun1" --portal "debby6:3260" --op=update --name node.session.auth.authmethod --value=CHAP<br />root@ubu1104:/etc/iscsi# iscsiadm -m node --targetname "iqn.2010-02.be.linux-training:storage.lun1" --portal "debby6:3260" --op=update --name node.session.auth.username --value=isuser<br />root@ubu1104:/etc/iscsi# iscsiadm -m node --targetname "iqn.2010-02.be.linux-training:storage.lun1" --portal "debby6:3260" --op=update --name node.session.auth.password --value=hunter2</pre><br />That's it!

The fee goes to SABAM (think MPAA).<br /><br />Radio used to be free, to promote music so people would go and buy music. But more and more everyone has to pay because people (could be) listening: first only concerts and parties, then work environments like shops, then waiting rooms, truck drivers, and now taxi drivers. How long will it take until there is a tax on our ears ?! No, I'm not kidding(*), the MAFIA(sorry I meant SABAM) will get there!<br /><br />Who do we pay ?! The 200 people working for SABAM ? Talk to any *real* artist and ask them how much they get from SABAM, because it is supposed to be all for the 'poor' artists. We already pay <a href="http://www.sabam.be/">the rich and powerful</a> for the music we buy, we pay a second time for the storage media where we keep the music (cd/usb/harddisk,...), so starting today we will pay three times when taking a taxi while listening to our own music. We could soon be paying a fourth time via our monthly internet connection payments. And I am probably forgetting a couple...<br /><br />Why do people accept this ? What's the benefit of hauling money to SABAM for society ? What do we get in return ? It seems to me that this is a classical story of the rich getting richer... for doing absolutely nothing.<br /><br /><b>We should all refuse to buy any kind of music, turn off the radio and not play any audio for a whole month! Yes, make November 2011 the month of protest against the storm on SABAM taxes.</b><br /><br /><br />(*) It reminds of an old story. Put a frog in boiling water, and it will jump out immediately. Put a frog in cold water and slowly heat it up... the frog will stay put and die. Slow increments are easier to accept than sudden changes, but the end result is the same.<br /><div><br /></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-6123802657278683561?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com1tag:blogger.com,1999:blog-18697195.post-1058874165697793482011-06-26T01:41:00.004+02:002011-06-26T01:58:17.572+02:00A reminder for myself on how to configure bluetooth for <a href="http://en.wikipedia.org/wiki/Lego_Mindstorms_NXT_2.0#Next_Byte_Codes_.26_Not_eXactly_C">NXT</a> <a href="http://www.youtube.com/watch?v=4YZeX8ti7Io">devices</a>.<br /><br />Turn on all devices and activate bluetooth on the Linux, then:<br /><pre>$ hcitool scan<br />Scanning ...<br /> 00:16:53:08:XX:XX Julie<br /> 00:16:53:0B:XX:XX Mercedes</pre><br />Then configure /etc/bluetooth/rfcomm.conf like this:<br /><pre>$ cat /etc/bluetooth/rfcomm.conf<br />rfcomm0 {<br />bind yes;<br />device 00:16:53:0B:XX:XX;<br />channel 1;<br />comment "Mercedes";<br />}<br /><br />rfcomm1 {<br />bind yes;<br />device 00:16:53:08:XX:XX;<br />channel 1;<br />comment "Julie";<br />}</pre><br />Then check the binding (as root):<br /><pre># rfcomm release all &amp;&amp; rfcomm bind all &amp;&amp; rfcomm<br />rfcomm0: 00:16:53:0B:XX:XX channel 1 clean<br />rfcomm1: 00:16:53:08:XX:XX channel 2 clean</pre><br />Then create an nxt.dat file in ~ :<br /><pre>$ cat /home/paul/nxt.dat<br />BTH::JULIE=BTH::JULIE::00:16:53:08:XX:XX::5<br />BTH::MERCEDES=BTH::MERCEDES::00:16:53:0B:XX:XX::5</pre><br />Then <a href="http://bricxcc.sourceforge.net/nbc/">compile and download to the NXT</a>:<br /><pre>nbc foo.nbc -O=bar.rxe<br />nbc -b -d -S=BTH::Julie bar.rxe</pre><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-105887416569779348?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-69178260843263007462011-06-17T10:16:00.005+02:002011-06-17T10:25:18.382+02:00Packages installed after default ubuntu install (personal bookmark).<br /><pre>root@mac:~# history | grep 'aptitude install'<br /> 11 aptitude install nvidia-settings nvidia-bl-dkms \<br /> pommed vim nfs-common wicd<br /> 45 aptitude install azureus wesnoth chromium-browser<br />104 aptitude install virtualbox-4.0<br />139 aptitude install wireshark wireshark-gnome<br />152 aptitude install gimp<br />173 aptitude install openssh-server<br />180 aptitude install pdfedit<br />201 aptitude install ttf-bitstream-vera<br />206 aptitude install unrar<br />219 aptitude install imagemagick<br />220 history | grep 'aptitude install'</pre><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-6917826084326300746?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com1tag:blogger.com,1999:blog-18697195.post-45964725732797999642011-06-07T15:30:00.005+02:002011-06-07T15:41:23.295+02:00<a href="http://en.wikipedia.org/wiki/World_IPv6_Day">8th of June</a> is tomorrow already!<br />My humble contribution is to teach networking students tonight about ipv6.

Disregarding the fact that I oppose the eight layered governance of a random street(*) in my city, I would like to redraw the current map of Flanders.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/-2R-xlpgPr-8/TYnO-b60tII/AAAAAAAAAYE/WXj3snB0dU4/s1600/vlaanderen.gif"><img style="cursor: pointer; width: 400px; height: 161px;" src="http://1.bp.blogspot.com/-2R-xlpgPr-8/TYnO-b60tII/AAAAAAAAAYE/WXj3snB0dU4/s400/vlaanderen.gif" alt="" id="BLOGGER_PHOTO_ID_5587224384771503234" border="0" /></a><br /><br />One of the main issues that prevents this country from having a government resolves around (imho ridiculous) language problems in and around Brussels (the brown area). Brussels is surrounded by (officially) Dutch speaking communities, but is itself mainly French-speaking.<br />Bad governance between 1970 and 2010 resulted in discrepancies (for instance: French-speaking people in Dutch-speaking territory <a href="http://en.wikipedia.org/wiki/Brussels-Halle-Vilvoorde">BHV</a> can vote for French-speaking politicians, but Dutch-speaking inhabitants of the French-speaking part of Belgium cannot vote for Dutch-speaking politicians).<br /><br />Also, Brussels is structurally way too small to make decisions that it should be capable of making (about its airport/highways/public transport/industry/...), since those are mainly in Dutch speaking parts outside Brussels (falling under another government).<br /><br />The new map:<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/-qNgSAVozZ2I/TYnSKce2k9I/AAAAAAAAAYM/HnTAU9y6Bd8/s1600/vlaanderen2.gif"><img style="cursor: pointer; width: 400px; height: 161px;" src="http://3.bp.blogspot.com/-qNgSAVozZ2I/TYnSKce2k9I/AAAAAAAAAYM/HnTAU9y6Bd8/s400/vlaanderen2.gif" alt="" id="BLOGGER_PHOTO_ID_5587227889615934418" border="0" /></a><br /><br />This new map enlarges Brussels so that it can manage the areas that currently surround Brussels but that economically and structurally belong to Brussels. Another advantage is that adding more Dutch-speaking people to Brussels makes it more balanced linguistically.<br />The red part is the new province of Leuven. Some municipalities from the former province of Vlaams Brabant migrated to neighboring provinces.<br /><br />(*) Depending on what happens in a random <a href="http://en.wikipedia.org/wiki/Antwerp">Antwerp</a> street, one or more of the following eight 'governments' is responsible:<br />- district (part of the city)<br />- gemeente (the city council)<br />- kanton (district, smaller than a province)<br />- provincie (province)<br />- gemeenschap (the Flemish Community)<br />- gewest (the Flemish Region)<br />- land (Belgium)<br />- Europese Unie (European Union)<br />What happened to the <a href="http://en.wikipedia.org/wiki/KISS_principle">KISS strategy</a> ?!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-1401388843624654271?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com2tag:blogger.com,1999:blog-18697195.post-49725819651577805902011-02-20T11:57:00.004+01:002011-02-20T12:48:49.574+01:00Yesterday I tried setting up <a href="http://library.gnome.org/users/gnome-access-guide/stable/ats-2.html.en">orca magnifier</a> on a freshly installed (fully updated) Ubuntu 10.10. The moment you check the magnifier checkbox the screen becomes garbled (all window borders disappear, about one quarter of the screen is magnified, the rest is garbled). The 'apply' and 'cancel' buttons are invisible (yet they work if you can guess their position).<br /><br />Switching from the default to nvidia drivers makes no difference.<br /><br />First we tried on an Acer Aspire 17-inch laptop, next we tried a 15-inch Apple Macbook Pro. The results are identical!! (yes i tried removing the orca config, creating a new user, reboot, ...)<br /><br />Is there an alternative for orca magnifier ? (Because the Ubuntu/Orca forums don't help much.)<br /><br />Will it work in Debian or Fedora ? (I would have to burn the cd and drive 100km to test this...)<br /><br />Do you know people that actually use orca magnifier on Ubuntu ?<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-4972581965157780590?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-81705631410888333542010-12-27T13:23:00.004+01:002010-12-27T14:03:11.814+01:00<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_ylVJKqjYoOw/TRiNUWolAtI/AAAAAAAAAX4/00aBB4mUcUQ/s1600/newbyzance_newharlem_newyork.jpg"><img style="cursor: pointer; width: 400px; height: 353px;" src="http://1.bp.blogspot.com/_ylVJKqjYoOw/TRiNUWolAtI/AAAAAAAAAX4/00aBB4mUcUQ/s400/newbyzance_newharlem_newyork.jpg" alt="" id="BLOGGER_PHOTO_ID_5555345521174184658" border="0" /></a> A <a href="http://blogs.tijd.be/cif/2010/06/kan-nmbs-irailbe-stoppen.html">friend</a> gave me an excellent French series of comic books called <a href="http://fr.wikipedia.org/wiki/Uchronie%28s%29">Uchronie(s)</a>. Or is it three series ?<br /><br />Each series is about a different city: New Byzance, New Harlem and New York. Or is it each time the same city in an alternate reality ?<br /><br />In New Byzance people dream fragments of the story in New Harlem. In New York they see the future, or is the past ? The idea is to read the first comic of each series, before reading any of the part 2's.<br /><br />All in all this is an interesting entanglement of stories, philosophy, history and cultures (to be concluded in 2011).<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-8170563141088833354?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-56013500849846684812010-11-07T00:31:00.021+01:002010-11-18T07:31:20.015+01:00<a href="http://inkscape.org/">Inkscape</a> is an easy (and <a href="http://en.wikipedia.org/wiki/Open_source">free</a>) tool to create <a href="http://en.wikipedia.org/wiki/Scalable_Vector_Graphics">scalable vector graphics</a>.

What follows are some real world experiences in dealing with Oracle since it took over the Sun Solaris trainings in Belgium.<br /><br />1. Remote labs are free!<br />Solaris teachers and students can now connect to remote labs with nice hardware for free. This is a great addition to the simple Intel machines in the classroom.<br /><br />2. Support is excellent!<br />In the weeks prior to the first Oracle Solaris training several people from Oracle called and/or emailed me to make sure everything was okay. These are real people that don't mind sharing their real email address and their real phone number. Cool! And they were very friendly and helpful!<br /><br />3. Support is excellent!<br />When sending an email on Sunday to report a problem, there is an almost immediate response from one of these real people. On a Sunday?!

Vrij te gebruiken, vrij te bestuderen, vrij te verspreiden en vrij aan te passen!<br /><br /><span style="font-weight: bold;"><strong>Vrij te gebruiken</strong></span> wil zeggen dat er geen beperkingen mogen zijn op het gebruik van de software. Iedereen is vrij om te kiezen waarvoor hij de software wil gebruiken. Als er beperkingen zijn op het gebruik van de software, dan is deze niet vrij.<br /><br /><span style="font-weight: bold;"><strong>Vrij te bestuderen</strong></span> wil zeggen dat iedereen de vrijheid moet hebben om naar de broncode te kijken om te begrijpen hoe de software werkt. Iedereen moet vrij kunnen spreken over de werking van de software. Als je software niet kan of mag bestuderen, dan is deze niet vrij.<br /><br /><span style="font-weight: bold;"><strong>Vrij te verspreiden</strong></span> wil zeggen dat je deze software mag doorgeven aan je buren en je vrienden. Als je software niet mag doorgeven aan anderen, dan is deze niet vrij. Als je verplicht bent een licentie te betalen, dan is de software niet vrij.<br /><br /><span style="font-weight: bold;"><strong>Vrij aan te passen</strong></span> wil zeggen dat de broncode beschikbaar moet zijn zodat je deze kan aanpassen, en wil ook zeggen dat je de software mag verspreiden met jou aanpassingen. Als je software niet kan of mag aanpassen, dan is deze niet vrij.<br /><br />Voorbeelden van vrije software : <a href="http://nl.wikipedia.org/wiki/Linux">Linux</a>, <a href="http://nl.wikipedia.org/wiki/Apache_%28webserver%29">Apache</a> (de <a href="http://news.netcraft.com/">meest gebruikte webserver</a>), <a href="http://www.mozilla.com/">Firefox</a>, <a href="http://nl.openoffice.org/">OpenOffice.org</a>, Azureus, <a href="http://wesnoth.org/">Battle for Wesnoth</a> (een leuk spel!), en <a href="http://nl.wikipedia.org/wiki/Lijst_van_opensourcesoftware">meer</a>.<br /><br />Bedrijven zoals Google en Facebook gebruiken bijna uitsluitend vrije software!<br /><br />Opgepast: Je hebt niet zomaar het recht om een logo (Firefox bijvoorbeeld) of een trademark over te nemen en te verspreiden!<br />Opgepast: Heel wat vrije software eist dat je de naam van de auteurs (programmeurs) blijft vermelden! En GPL software eist dat aanpassingen die je wenst te verspreiden onder dezelfde GPL licentie vallen.<br /><br /><br /><br /><br /><span style="font-weight: bold;"><strong>Softwarepatenten</strong></span><br /><br />Softwarepatenten zijn een heel gevoelig onderwerp. De strijd tegen softwarepatenten mag je vooral niet verwarren met een algemene strijd tegen patenten.<br /><br />In Europa is er geen wettelijk kader voor softwarepatenten (<a href="http://softwarepatenten.be">softwarepatenten.be</a>), maar dit weerhoudt grote bedrijven (IBM, Oracle, HP, Microsoft, ...) er niet van om massaal softwarepatenten te registreren. Sommige van deze patenten zijn verrassend triviaal; zowat elke website gebruikt <a href="http://softwarepatenten.be/voorbeeld/webwinkel.html">tientallen softwarepatenten</a>. Bijna alle software die er bestaat gebruikt wel enkele van de tienduizenden geregistreerde softwarepatenten.<br /><br />Een van de grote nadelen van softwarepatenten is dat ze innovatie serieus tegenhouden. Je kan je als KMO immers niet verdedigen tegen een massa advokaten van de grote bedrijven die staan te zwaaien met softwarepatenten (met als gevolg dat je failliet gaat of wordt opgekocht).<br /><br />Vroeger waren er geen softwarepatenten, en gelukkig maar! Stel je voor dat AT&amp;T in 1970 in staat was geweest om software te patenteren, dan hadden we nu maar 1 besturingsysteem (Unix), en maar 1 officeapplicatie (<a href="http://www.linux-training.be/funhtml/ch08.html">vi</a>) en 1 zoekmachine (<a href="http://www.linux-training.be/funhtml/ch07.html#id2557576">find</a>). Bedrijven als Google, Facebook of Microsoft zouden nooit kunnen bestaan hebben.<br /><br />Vrije software valt niet te verzoenen met softwarepatenten (in de vorm dat ze vandaag bestaan in de USA).<br /><br /><br /><br /><span style="font-weight: bold;"><strong>Open Standaarden</strong></span> (en open formaten)<br /><br />Open Standaarden zijn standaarden (noem het gerust talen, protocols of formaten) die voor iedereen beschikbaar zijn om te gebruiken. Een bekend voorbeeld hiervan is HTML. HTML is een standaard die er sinds 1993 voor zorgt dat we documenten op internet kunnen raadplegen. Iedereen mag een programma schrijven om HTML te lezen (Internet Explorer, Firefox, Google Chrome, Opera, ...). Een ander voorbeeld is PDF, een documentformaat dat ervoor zorgt dat het document er op elke computer hetzelfde uitziet (en identiek uit elke printer rolt). Ook al is PDF ontwikkeld door Adobe, de standaard is exact beschreven door Adobe en vrij te gebruiken.<br />Het grote voordeel van open standaarden is dat je onafhankelijk bent van een leverancier!<br /><br />Het meest gekende tegenvoorbeeld van een open standaard is het formaat gebruikt door MS Office 95/98/2000/2003 (.doc .xls ...). Dit gesloten formaat is eigendom van Microsoft en enkel te openen met producten van Microsoft. Je kan als organisatie niet zelf een product schrijven dat deze documenten perfect kan gebruiken, want Microsoft wil niet vertellen hoe het .doc formaat in elkaar steekt.<br /><br />Het grote nadeel van gesloten standaarden is dat je geen keuze hebt van leverancier. Indien je bedrijfsinformatie aangemaakt hebt met MS Office 2000, dan ben je afhankelijk van Microsoft om toegang te krijgen tot jou eigen gegevens.<br /><br /><br /><span style="font-weight: bold;"><strong>Open Source</strong></span><br /><br />Als we nu terug gaan naar de Engelse taal, dan komen we een probleem tegen. De Nederlandse woorden gratis en vrij zijn duidelijk verschillend, maar worden in het Engels beide vertaald naar 'free'. Dit zorgt voor heel wat verwarring rond 'free software', mensen interpreteren het als gratis software, of erger nog, verwarren het met freeware.<br />Daarom spreken heel wat mensen van open source software (of gewoon open source), terwijl ze eigenlijk vrije software bedoelen.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-2003649341672513838?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-91189294788497941172010-06-27T16:16:00.004+02:002010-06-27T16:30:49.961+02:00<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_ylVJKqjYoOw/TCdemlMfHGI/AAAAAAAAAWw/qPHX6LTSiKY/s1600/davideddings.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 300px; height: 320px;" src="http://3.bp.blogspot.com/_ylVJKqjYoOw/TCdemlMfHGI/AAAAAAAAAWw/qPHX6LTSiKY/s320/davideddings.jpg" alt="" id="BLOGGER_PHOTO_ID_5487458687886761058" border="0" /></a><br />I disagree with <a href="http://blog.elisehuard.be/">the sound of one hand clapping</a>, <a href="http://en.wikipedia.org/wiki/The_Belgariad">David Eddings</a> is getting better after the first three books.

Facebook has won, they <a href="http://www.google.com/search?tbs=nws:1&amp;q=facebook+%22world+domination%22">officially</a> own the personal computer.<br />More and more popular websites can read <a href="http://www.google.com/search?q=facebook%20privacy&amp;tbs=nws:1">your private facebook</a> data when you visit them, even when the facebook-tab is not open. I'm not sure that logging out helps, since technically cookies can still identify you. I don't like this facebook-knows-all world.<br /><br />About Privacy...<br />"So don't put private stuff on facebook!" I hear you say. "Not that easy!" I reply "because facebook is <a href="http://www.google.com/search?tbs=nws:1&amp;q=%22facebook+connect%22">keeping bloody track</a> of your online movements, even when you haven't given it private info or when you don't post anything on your wall."<br />Not convinced yet, let me quote <a href="http://www.wired.com/epicenter/2010/05/facebook-rogue/">Ryan Singel</a>: 'Now, say you you write a public update, saying, “My boss had a crazy great idea for a new product!” Now, you might not know it, but there is a Facebook page for “My Crazy Boss” and because your post had all the right words, your post now shows up on that page.'<br />How long will it take until facebook posts stuff in your name on a dozen websites, just because you (accidentally of course) stumbled upon <a href="http://www.google.com/search?q=%22doe+nooit+wat+onkuisheid+is%22">www.hotredheadsinstockings.com</a>.<br /><br />About deleting your facebook account...<br />This <a href="http://www.readwriteweb.com/archives/what_happens_when_you_deactivate_your_facebook_acc.php">link</a> explains how difficult it is to really delete your account.<br /><br />Anyway, starting today I'll split my browsing habits, isolating facebook in its own <a href="http://www.virtualbox.org">private virtual machine</a>.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-2283483601976728683?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com3tag:blogger.com,1999:blog-18697195.post-80650906713908850262010-05-05T22:09:00.004+02:002010-05-05T22:30:46.320+02:00Na het lesgeven, maar voor het schaken nog effe op het Zuid de dames (met sacochen) goeiedag gezegd.<br /><br />Met dank aan <a href="http://www.bnox.be/">Clo</a> voor de organisatie van de <a href="http://brusselsgirlgeekdinner27.pbworks.com/FrontPage">27ste girlgeekdinner</a>.

Hopelijk is er geen tram of bus op lijn 13, of een station met 13 sporen.<br /><br />Mogen kinderen hun dertiende verjaardag nog vieren ? En wat als ik in september 13 studenten heb in mijn klas ?<br /><br />Ondertussen ken ik een koppel met tetrafobie (angst voor het getal 4).

To never have a file twice on your system (and thus save disk space).<br />(they need to know that deleting files with hard links doesn't add free space)<br />2. For compatibility with legacy applications that use old file locations (without the need to rewrite those applications).<br />3. Because Linux programs know how they are called, mke2fs, mkfs.ext2 and mkfs.ext3 can be the same file, but with distinct functionality.<br /><br />Sometimes these arguments fail to convince students of the usefulness of hard links. What would you say ?<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-5583640488996651339?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com16tag:blogger.com,1999:blog-18697195.post-3086114321476491012010-03-12T13:32:00.005+01:002010-03-12T13:43:40.833+01:00Wil iemand eens tegen <a href="http://www.standaard.be/">De Standaard</a> zeggen dat we in 2010 zijn ?

En de vrt, die mag niet knoeien!<br /><br />Annik (zonder c) stuurde mij een filmke over Annick (met c). U kan het bekijken op <a href="http://www.deredactie.be/permalink//1.646326">deredactie.be</a> (47 seconden) of de iets langere versie op <a href="http://www.youtube.com/watch?v=JYCBP3H6eEU">youtube</a> (80 seconden).<br /><br />In het filmke wordt getoond hoe <a href="http://www.annickderidder.be/">Annick De Ridder</a> het woord wil nemen, hoe ze verveeld met haar hoofd zit te schudden, en vervolgens het woord wordt afgenomen door Mijnheer Peumans die brutaal de micro uitschakelt. Ik wil niet discuteren over het feit of die micro afzetten gerechtvaardigd was of niet. Ik heb wel een probleem met de vrt die hier de volgorde van de feiten verdraaid.<br /><br />Mevrouw De Ridder was pas verontwaardigd met haar hoofd aan het schudden *<strong><span style="font-weight: bold;">nadat</span></strong>* de micro brutaal was afgezet. Maar dat blijkt niet uit de chronologie die de vrt laat uitschijnen. Ze hebben latere beelden (seconden 43 tot 47 in de youtube link) bewust *voor* het wegslaan van de micro geplakt, maar hebben terwijl wel de audio laten doorlopen zodat het een natuurlijke voortgang lijkt.<br /><br />Wat bezielt onze openbare omroep eigenlijk om te knoeien met de volgorde waarin de feiten zich voordoen ? Je zou kunnen argumenteren dat het hier om een detail gaat, op voorwaarde dat dit een eenmalig 'ongelukje' was. Helaas voor de vrt ben ik een dertiger die zich herinnert hoe ze ooit hetzelfde uithaalden met Mijnheer Happart in Voeren. Toen was het overduidelijk omdat de rtbf dezelfde beelden wel in de goeie volgorde had getoond.<br /><br />Ik vind dat straf. Het doet me denken aan <a href="http://en.wikipedia.org/wiki/Nineteen_Eighty-Four">1984</a> van George Orwell waar Big Brother ook nieuwsfeiten 'aanpast'. Zijn er zo nog voorbeelden ? (Ik leef zelf al lang zonder TV, en prullen zoals dit zullen mij niet snel naar deredactie.be lokken.)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-1823694989263188411?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com6tag:blogger.com,1999:blog-18697195.post-57097635813268710112009-12-15T01:14:00.001+01:002009-12-15T01:15:54.700+01:00Als je samenkomt om te besturen, dan wil je iets bereiken. Er zijn agendapunten die moeten besproken worden, en er zijn de mensen waarmee je samen zit. Je moet dossiers kennen, en je moet luisteren naar elkaar. In dat laatste was ik vanavond, als toeschouwer gelukkig, zwaar teleurgesteld.<br /><br />Ok ok, het is de gewoonte om elkaar te negeren hier. De deelnemers kennen elkaars standpunten, ze zitten immers al jaren samen op deze maandelijkse meetings. Iedereen hoort in een vakje, elk vakje is duidelijk omlijnt. Elk vakje heeft een leider.<br /><br />Maar ja, dat maakt niet uit. Iedereen is een individu en wil als mens gerespecteerd worden. Ik kan me niet voorstellen dat het niet een beetje knaagt als er niet geluisterd wordt. De micro gaat aan voor jou, en de man naast je begint zijn krant te lezen, de dame rechtover typt naarstig op de smartphone, iemand loopt al gsm-end buiten, en je buren lachen toch wel erg luidruchtig.<br /><br />Het kabaal was al ver boven mijn grens van tolerantie toen mijnheer De Blust na meer dan twee uur van rumoerige monologen dan toch eens vroeg om aandacht. Het ging over ons klimaat. Niet dat het veel hielp, maar hij had wel degelijk een punt.<br /><br />De max, was mevrouw Pooters die om half twaalf nog een reeks vragen afvuurde voor de schepen. Een hele reeks, op zo'n laat uur. De schepen had een even uitgebreid antwoord, maar mevrouw Pooters schonk hem geen aandacht, niet de minste. Het werd mijnheer de schepen te veel, en hij begon te roepen, te schreeuwen. De reactie van mevrouw Pooters haar partij was even luidruchtig.<br /><br />Er werd ook gepraat over het nieuwe stadion, de inschrijving van kinderen in scholen, subsidies en maatregelen allerhande. Ach, altijd wel leuk zo'n avondje Antwerpse gemeenteraad.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-5709763581326871011?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-46234814195480735352009-11-14T23:20:00.004+01:002009-11-14T23:27:52.323+01:00Wow now this is a good book! <a href="http://en.wikipedia.org/wiki/Soul_of_the_Fire">Soul of the fire</a>, fifth book in the <a href="http://en.wikipedia.org/wiki/The_Sword_of_Truth">Sword of Truth</a> series, and definitely the best of the first five (reading number six Faith of the Fallen now).<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-4623481419548073535?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-36549369799743887872009-11-14T00:28:00.006+01:002009-11-14T00:49:48.665+01:00Yes it has been a long time since the last blogpost.

I tried the <a href="http://mytracks.appspot.com/">My Tracks</a> application again today, and it works flawlessly. Only the start is a bit slow, so you miss the first 100 meters of your trip. But that's normal for GPS applications I guess.<br /><br />This My Tracks application can track via GPS where you go with the phone. I used it to create this Google map with my bicycle ride through Antwerp today.<br /><br /><iframe marginheight="0" marginwidth="0" src="http://maps.google.com/maps/ms?ie=UTF8&amp;hl=en&amp;msa=0&amp;msid=116056626642037262204.0004733be983f4fee1def&amp;ll=51.215054,4.416919&amp;spn=0.034161,0.043404&amp;t=h&amp;output=embed" frameborder="0" height="350" scrolling="no" width="425"></iframe><br /><small>View <a href="http://maps.google.com/maps/ms?ie=UTF8&amp;hl=en&amp;msa=0&amp;msid=116056626642037262204.0004733be983f4fee1def&amp;ll=51.215054,4.416919&amp;spn=0.034161,0.043404&amp;t=h&amp;source=embed" style="color: rgb(0, 0, 255); text-align: left;">Cycling thru Antwerp</a> in a larger map</small><br /><br />I regularly tour <a href="http://en.wikipedia.org/wiki/Antwerp">the city</a> like this.

Good book, almost 800 pages about wizards, a magic sword, a dragon, beautiful women and other wonderful things.

Most of the software I use is <a href="http://en.wikipedia.org/wiki/FLOSS">Free</a>.<br /><br />Until today, I frequently used <a href="http://www.vmware.com/download/server/">vmware server</a>. Now I switched to <strong><a href="http://www.virtualbox.org/">Virtualbox</a></strong>! Yeah!<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_ylVJKqjYoOw/SkJ83d-JbyI/AAAAAAAAAVM/LNQNwjrKH48/s1600-h/VirtualBox.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 229px;" src="http://3.bp.blogspot.com/_ylVJKqjYoOw/SkJ83d-JbyI/AAAAAAAAAVM/LNQNwjrKH48/s320/VirtualBox.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5350976599649513250" /></a><br /><br />My first attempt was a virtual Red Hat Enterprise Server. Virtualbox can use the .vmdk files from vmware, but that didn't work with this 20G virtual disk (split in 2GB parts). Putting the files together with<pre>vmware-vdiskmanager -r RHEL52.vmdk -t 0 flat.vmdk</pre> solved that problem. RHEL53 is running excellent now!<br /><br />Second test was installing a Fresh Ubuntu 9.04. This was really easy! I like this virtualbox wizard, it asks all the right questions.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_ylVJKqjYoOw/SkJ9goZ6oZI/AAAAAAAAAVU/Dk-QDX2f8BI/s1600-h/CreateNewVirtualMachine.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 273px;" src="http://1.bp.blogspot.com/_ylVJKqjYoOw/SkJ9goZ6oZI/AAAAAAAAAVU/Dk-QDX2f8BI/s320/CreateNewVirtualMachine.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5350977306824974738" /></a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-6435212915144846009?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-27320329452023114872009-06-23T22:49:00.005+02:002009-06-23T23:40:50.363+02:00'k had al lang zin om het <a href="http://nl.wikipedia.org/wiki/Stadhuis_%28Antwerpen%29">stadhuis</a> eens van binnen te zien. Ondergetekende rinkelde dus deze avond omstreeks 18u15 aan de deurbel om een <a href="http://www.antwerpen.be/eCache/ABE/80/34/080.cmVjPTgwMTk4MTQ.html">gemeenteraadscomissie</a> te volgen. "Ha maar mijnheer, die vinden vandaag uitzonderlijk in het Felix pakhuis plaats." (jaja, 't wordt tijd dat ik websites leer lezen ;-)<br /><br />Twintig minuten later, op de zesde verdieping, begon licht rumoerig (en te laat) de commissie sociale zaken. Toch wel boeiend om vraag en antwoord te volgen. De beleefdheid naar de voorzitter toe viel wel op.<br /><br />Per toeval dan met <a href="http://nl.wikipedia.org/wiki/Filip_Dewinter">Filip De Winter</a> en collega's de lift in naar beneden met het volgende gesprek (ge gaat het niet geloven mannekes):<br /><br />politika: "Seg ik kan de vrijdag niet komen. Ik moet naar een begrafenis."<br />FilipDW: "Ah. En is het erg ?"<br />Hilariteit en morbide gebarentaal alom.<br /><br />Net toen ik besliste om het af te bollen zag ik dat er een derde commissie was (die stond niet op de <a href="http://www.antwerpen.be/eCache/ABE/80/34/080.cmVjPTgwMTk4MTQ.html">website</a>) over luchtkwaliteit en fijn stof. Wow, dat is wel een boeiend topic (en on topic voor mij sinds ik in 't <a href="http://www.antwerpen.be/">Stad</a> woon). Ook deze voorstelling (het was ne powerpoint van vito) begon iets te laat, maar was wel boeiend. <strong><span style="font-weight: bold;">Blijkbaar komt bijna 90 procent van het fijne stof in Antwerpen niet uit de Antwerpse agglomeratie, maar uit Londen, Vlaanderen, Europa en Wallonie</span></strong> (waait er dan wind van de Walen naar hier ?). Er waren nog boeiende grafiekjes, sattelietfotos en besluiten (op de ring is meer fijn stof dan in de binnenstad!).<br /><br />Wat ik in de vragenronde dan niet verwachtte was een licht irritante anti-openvld sfeer nadat <a href="http://www.annickderidder.be/">Annick De Ridder</a> er <a href="http://www.facebook.com/annickderidder?v=feed&amp;story_fbid=95504505422&amp;ref=mf">een lap</a> op had gegeven (imho een goeie lap behalve dat laatste puntje). Daar werd ze toch serieus bij naam op afgebroken door de... euh 'anderen' (mijn name-to-face table voor politiekers is niet echt up to date). Of hoe een niet-deelname aan de Vlaamse regering toch invloed kan hebben...<br /><br />Soit, hopelijk leest niemand dit artikel als kritiek, ik heb de indruk dat heel wat mensen daar goed werk leveren!<br /><br />En de echte inhoud van de debatten ? Daarvoor moet ge zelf maar langskomen ;-)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-2732032945202311487?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-43630118426978033302009-06-23T10:49:00.004+02:002009-06-23T11:51:08.838+02:00<strong><span style="font-weight:bold;">daily spam</span></strong><br /><br />Number of spam mails received on @cobbaut.be.

With every registration on a website, I used a unique address in the @cobbaut.be domain. This unique name contains where(website), when(date) and reason for giving an email address (usually no_spam_please). All these addresses are easily recognized by Thunderbird and manually added to the Junk filter upon receiving the first spam.<br /><br /><strong><span style="font-weight:bold;">data mining the spam</span></strong><br />- Two months ago zattevrienden.be started <a href="http://www.zattevrienden.be">spamming</a> the 1998 advalvas registration.<br />- About 8000 monthly spams are sent to my public 2006 slashdot address<br />- 33072 spams were sent to an address I used once to play a stupid flashbased online game (I played it once!)<br />- 15163 spams sent to an address used to communicate with one single person only!<br />- 16751 spams sent to my old usenet registration<br />- ... let me know if you want me to run grep on my spam collection<br /><br /><strong><span style="font-weight:bold;">gmail solution</span></strong><br /><a href="http://mail.google.com">Gmail</a> has the excellent feature that lets people mark a mail as spam and takes this 'mark' into account when filtering any Inbox.<br /><br />For example today vroom.be sent out spam: "Je ontvangt deze mail omdat je tijdens jouw registratie hebt aangegeven op de hoogte te willen worden gehouden door geselecteerde partners van Vroom.be." Utter <a href="http://www.vroom.be">bullshit</a> of course since I have never been to that website.

(Can someone with mysql knowledge please review this ?)<br /><br />Finally updated init and booting, they are two chapters now. Booting is chapter 17, init is chapter 18. The practices for these chapters are not done yet, and lilo could use a bit more info.<br /><br />Notes to self:<br />- chapter 13 (more about bash) is dreadful, high priority!<br />- idem ditto for 22.scheduling and 24.memory management<br /><br />By the way, there is really no point in putting old copies of this book online (like on scribd).

And even though they all split in a French-speaking and a Dutch-speaking part fifty to sixty years ago, these <strong><span style="font-weight: bold;">big three</span></strong> ruled Belgium for more than one hundred years.<br /><br />The Seventies and Eighties saw the rise of extremist parties like <a href="http://nl.wikipedia.org/wiki/Volksunie">VU-Volksunie</a> and <a href="http://nl.wikipedia.org/wiki/Groen%21">Agalev</a>. Both joined the federal government briefly, but dissolved right after that. The Nineties saw the rise of <a href="http://en.wikipedia.org/wiki/Vlaams_Belang">Vlaams Blok</a>.<br /><br />Look at the total percent of votes that went to the <strong><span style="font-weight: bold;">big three</span></strong> :<br /><pre>1985: 79%<br />1987: 79%<br />1991: 71%<br />1995: 72%<br />1999: 64%<br />2003: 73% (including the Dutch-speaking socialist <a href="http://en.wikipedia.org/wiki/Kartel">kartel</a>)<br />2007: 70% (including several <a href="http://en.wikipedia.org/wiki/Kartel">kartels</a>)<br /></pre>Some of these kartels are history today.<br /><br />The Naughties already made clear that many new and/or extremist parties (<a href="http://en.wikipedia.org/wiki/List_Dedecker">LDD</a>, Ecolo, Vlaams Belang, Groen) might rival the election results of the <strong><span style="font-weight: bold;">big three</span></strong> (who are six now).<br /><br />Too many parties will get around ten percent of all Belgian votes (including the six from the <strong><span style="font-weight: bold;">big three</span></strong>). Forming a government will become very difficult.<br /><br />The upcoming elections of June 7th are European and regional (not federal!), but they will have an impact on the federal government. Many people expect federal elections in October 2009.<br /><br /><strong>So what's the choice for the upcoming elections ?</strong><br /><br />My European vote might go to <a href="http://www.bartstaes.be">Bart Staes</a>, the only politician in Europe to have a clue about open standards, and who also <a href="http://www.softwarepatenten.be/rapport/ipred2">votes accordingly</a>.<br /><br />On the Flemish front:<br />- LDD wants smoking back in restaurants ?! No!<br />- Groen wants to halt nuclear energy ! No!<br />- CD&amp;V the good old <a href="http://en.wikipedia.org/wiki/Fairy_tale">catholics</a>, with <a href="http://en.wikipedia.org/wiki/Yves_Leterme">this miserable failure</a>?! No!<br />- Vlaams Belang is <a href="http://en.wikipedia.org/wiki/Cordon_sanitaire">excluded by all other parties</a> (except LDD?), this gives them some sympathy. But they lack a real program, and get lots of votes from racists. No!<br />- N-VA has <a href="http://peterdedecker.eu/">Peter Dedecker</a>, but they are too Flemish extremist. No!<br /><br />This leaves only <a href="http://nl.wikipedia.org/wiki/Open_Vlaamse_Liberalen_en_Democraten">OpenVLD</a> (the good old liberals) and <a href="http://nl.wikipedia.org/wiki/SP-A">SP.a</a> (the good old socialists). One could vote for blue <a href="http://en.wikipedia.org/wiki/Karel_De_Gucht">integrity</a> and <a href="http://en.wikipedia.org/wiki/Guy_Verhofstadt">experience</a> ? Or one could follow <a href="http://www.pietel.be/verkiezingen-2">Pieter</a> and vote for red <a href="http://www.kathleenvanbrempt.be/index.php?option=com_rsgallery2&amp;Itemid=56&amp;page=inline&amp;catid=5&amp;id=11&amp;limit=1&amp;limitstart=4">charm</a> and <a href="http://www.hln.be/hln/nl/921/Kanaal-Nieuws/photoalbum/detail/329297/398710/1/index.dhtml">beauty</a> ;-)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-7623608227634620102?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com6tag:blogger.com,1999:blog-18697195.post-39349205070058130662009-05-19T14:25:00.004+02:002009-05-19T14:39:41.672+02:00/proc/bus/usb/devices is still mentioned in the manpage of lsusb, but not existing on my current Ubuntu (2.6.24) and RHEL5 (2.6.18) system.<br /><pre><br />root@laika:~# ls -al /proc/bus/usb/<br />total 0<br />dr-xr-xr-x 2 root root 0 2009-05-19 14:24 .<br />dr-xr-xr-x 6 root root 0 2009-05-19 10:15 ..<br />root@laika:~# <br /></pre><br />The /proc/bus/usb/ structure is however present on Debian (2.6.17), including the devices file.<br /><br />Where does the lsusb command go to get usb device information ?

Dat werk heeft de <a href="http://www.ginsys.be/">Serge</a> (ook nen toffe pee) gekregen.<br /><br />Nee het is niet ironisch.<br /><br />Gisteren is <a href="http://en.wikipedia.org/wiki/Bedford">Sandra</a> (ook een toffe madam) in 't <a href="http://www.antwerpen.be/">Stad</a> geland. Vandaag heeft ze superlekker gekookt! Nog gebeld met de Christian (ook nen toffe pee) en toffe mailkes gekregen van Annik (ook een toffe madam) en een sms-ke van <a href="http://www.tenderfeelings.be/index.php/inge">Inge</a> (ook een toffe madam).

't is uitkijken naar de vele foto's. Er is een foto van Goya en mij, waar de context belangrijk is om geen verkeerde conclusies te trekken!! Ah, en <a href="http://limeblogt.wordpress.com/">Kato</a> (ook een toffe madam) had haar <a href="http://limeblogt.wordpress.com/2008/08/05/souvenir/">souvenir</a> (ook nen toffe pee) bij. <a href="http://www.blogologie.be/">Maarten</a> (ook nen toffe pee) had een goei idee, ik hoop dat hij het uitwerkt. Doen he Maarten!<br /><br /><a href="http://www.werkmens.be/">Koen</a> (ook nen toffe pee) ga ik beloven nooit nog zijn naam te vergeten. De gesprekjes met Ewoud, Lander, Tim, Filip en de Fre waren te kort, maar kben zeker dat het toffe mensen zijn!

Ze blokkeren een kinderporno site (<a href="http://www.standaard.be/Artikel/Detail.aspx?artikelId=DMF20090421_064&amp;ref=nieuwsoverzicht">artikel standaard.be</a>). Niemand kan er iets op tegen hebben, maar het zet wel een heel angstig precedent.<br /><br />Engeland is al een stapje verder, daar is sinds gisteren thepiratebay.org <a href="http://www.pcpro.co.uk/news/251609/bt-blocks-off-pirate-bay.html">geblokkeerd</a>. Nog voordat het proces tegen enkele medewerkers van the piratebay afgelopen is. De website zelf is trouwens (nog) niet veroordeeld.<br /><br />En voor de goede verstandhouding, het gaat wel degelijk over <a href="http://piratebay.org/">de website</a>, niet over die echte <a href="http://news.google.com/news?pz=1&amp;ned=us&amp;hl=en&amp;q=pirates+somalia">pirate bay</a> nabij Somalie.

De afwezigen hadden ongelijk.(*)<br /><br /><a href="http://www.e-zen.be">Béate Vervaecke</a> haar presentatie over Google Adwords was boeiend, zij weet goed waarover zij spreekt.<br /><br />Nadien sprak <a href="http://www.freshcommerce.be">Thomas Vande Casteele</a> over Google Analytics. Voor de tweede keer werd mijn verwachting overtroffen.<br /><br />Pieter Ardinois gaf een boeiend overzicht van <a href="http://en.wikipedia.org/wiki/QR_Code">QR codes</a>, met interessante praktijkvoorbeelden en business cases. Alle naamkaartjes waren voorzien van een qr code die naar je twitter account verwees.<br /><br /><a href="http://tijsvrolix.be/">Tijs Vrolix</a> sprak over enkele van zijn iPhone apps (en had zijn presentatie in 10 minuten gemaakt). 't was leuk!<br /><br />Steffest sprak over de <a href="http://www.arduino.cc/">Arduino</a> (ik moest aan de <a href="http://www.buglabs.net/">bug</a> denken) en over zijn tweetshirt project. Zijn demo's met de 81 ledjes en de wii waren zeker de moeite.<br /><br />De max was wel Stijn Wens met zijn ei! Heel goeie design van zijn slides. Hij vertelde me vooraf dat hij nog nooit een presentatie had gegeven, maar dat was er zeker niet aan te zien. Schitterend gewoon (hopelijk komt de video online). Zet wel je geluid af als je naar <a href="http://www.wens.be/">zijn website</a> gaat :(<br /><br />Verder heeft Johan Ronsse van <a href="http://www.netlash.com/">Netlash</a> nog enkele goeie tips gegeven om in de 'zone' te geraken. Hilke Ross sprak over hoe een muzikant een geek wordt. Al deel ik hier de bedenking van <a href="http://www.paeps.cx/weblog/">Philip</a> dat bloggen en twitteren(**) absoluut niet volstaan om als '<a href="http://www.paeps.cx/weblog/life/proliferation_of_geek_events.html">geek</a>' bestempeld te worden. Nancy Verbrugge bewees dat ze een pak sympathieker is dan <a href="http://www.microsoft.be">haar bedrijf</a>. Ze had enkele goeie tips bij over het maken van presentaties. Aster Saerens begeleidde een aangename en ontspannende 'beweeg' sessie, zeker de moeite!<br /><br />De details van de meeste sessie ontbreken, je had maar aanwezig moeten zijn.<br /><br />Bij deze nog een dikke dank voor de sponsors: <a href="http://www.nucleus.be/nl/nucleus/">nucleus</a>, <a href="http://www.devia.be/">devia</a>, <a href="http://www.chocolateque.com/">chocolateque</a>, <a href="http://10to1.be/">10to1</a>, <a href="http://theparkinglot.be/">the parking lot</a> en <a href="http://www.nespresso.com/precom/home_be_en.html">Nespresso</a>(geluid afzetten).<br /><br /><br />(*) Er waren zo'n <a href="http://barcampantwerpen.pbwiki.com/FrontPage">150 mensen ingeschreven voor deze editie</a>, en er kwamen er maar 70 opdagen.

It would show three blinking lights (num lock, caps lock, scroll lock) when powered on, but only for about ten seconds. Then the three lights stayed on, for another ten seconds, and then the laptop powered itself off.<br /><br />The week before my <a href="http://cobbaut.blogspot.com/2009/03/las-canadas-tenerife.html">vacation</a>, I was unable to use the laptop. It would <a href="http://en.wikipedia.org/wiki/Power-on_self-test">post</a> and <a href="http://en.wikipedia.org/wiki/Booting">boot</a>, upto the startup of <a href="http://en.wikipedia.org/wiki/GNOME_Display_Manager">gdm</a> ... and then it powered off. This was annoying!<br /><br />The <a href="http://www.discoveries.be/">shop</a> (excellent service btw) didn't find a solution. <a href="http://www.google.com/search?hl=en&amp;q=clevo+d900k+three+blinking+lights">Googling</a> the problem was not easy.<br /><br />The problem is now <a href="http://forum.notebookreview.com/showthread.php?t=175074">solved</a>.<br /><br />Tightening the screws of the video card solved the problem.

Maar het heeft wel jaren geduurd<br />eer ik die ingredienten gevonden had. Het feit dat ik in staat ben om toch te genieten van<br />een glas witte wijn maakt de zoektocht naar de boosdoeners alleen maar lastiger.<br /><br />Veel succes gewenst dus, met je queeste naar je allergie."</pre><br />Wat een luxe nu zeg! De jarenlange zoektocht naar maag/slokdarm problemen is al een tijdje voorbij. Tweemaal hebben ze mij met de ziekenwagen afgevoerd omdat ik bleek werd van de slokdarmpijn, maar de miserie is voorbij.<br /><br /><strong><span style="font-weight: bold;">De zoektocht...</span></strong><br /><br />Het begon ergens in 1993 ofzo, na een barbeque. Ik was 23 jaar, had genoten van het eten en drinken, maar het bekwam me niet. Het werd zo pijnlijk in de slokdarm dat ik echt bleek werd. Mensen die dat zagen, hebben toen de ziekenwagen gebeld (omdat ik naar mijn hart greep dachten ze...). De conclusie van de dokters (na 37 onderzoeken) was dat ik beter geen barbeque meer zou eten.<br /><br />Pas jaren later werd me duidelijk dat die bbq er niets mee te maken heeft, maar wel de Champagne die we kregen. Ik heb Champagne nooit lekker gevonden (wel in de mond, maar niet om door te slikken). Veel kans omdat de allergie voor Champagne er al langer was.<br /><br /><strong><span style="font-weight: bold;">Appels</span></strong><br /><br />Hetzelfde met appels. Als kind wou ik dat al niet eten...het bekwam mij gewoon nooit. Maar wel appelmoes (met brokken), of appels uit de microgolf.<br /><br /><strong><span style="font-weight: bold;">Avocado/Guacamole</span></strong><br /><br />Hier is het effect direct merkbaar. Zelfs voor mijn 23 jaar liet ik de guacamole portie dikwijls onaangeroerd in een Mexikaans restaurant.<br /><br /><strong><span style="font-weight: bold;">Witte Wijn</span></strong><br /><br />Witte wijn is lekker, en ik kan er van drinken...maar niet te veel. En zeker niet na het eten van een beetje appel of guacamole.<br /><br />Bizar dat kleine porties soms wel goed smaken, tot op het moment dat het teveel wordt.<br /><br /><strong><span style="font-weight: bold;">Noten</span></strong><br /><br />Gelukkig niet alle noten! Wel zeker zijn cashew en okkernoten. Misschien ook wel kastanjes. Ik blijf er af als ik kan, maar eet nog wel graag (en soms veel) pindanootjes.<br /><br /><strong><span style="font-weight: bold;">Oorzaken</span></strong><br /><br />Iemand zei me ooit dat (enkele van) deze allergie-en gerelateerd zijn aan berk/pollen allergie. Ik was inderdaad al serieus aan het snotteren vanaf mijn negen/tien jaar in de lente. Grassen/hooi zijn een verschrikking, en ik vecht met de huismijt (vandaar geen tapijt/gordijnen in mijn huis).<br /><br />Soit, misschien helpt dit berichtje iemand om zijn allergie-boosdoeners sneller te vinden.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-4177164639252008288?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-40285368639996888232009-02-09T11:06:00.000+01:002009-02-09T11:07:40.839+01:00paul@laika:~$ perl -e 'print scalar localtime(1234567890),"\n";'<br />Sat Feb 14 00:31:30 2009<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-4028536863999688823?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com3tag:blogger.com,1999:blog-18697195.post-86923602322758771532009-02-05T12:44:00.004+01:002009-02-05T12:50:15.894+01:00Years ago, i saw a shop in Leuven advertising photocopies for 0,20 eurocent.

Het woord Lossless (verliesvrij) in de term verwijst naar het feit dat de audiogegevens worden opgeslagen zonder dat daarbij gegevensverlies ontstaat.<br /><br />Het flac-formaat verschilt hierdoor onder andere van het mp3-formaat, een compressietechniek waarbij wel gegevens verloren gaan (lossy). Zo'n mp3-bestand dat vervolgens terug wordt omgezet in een wav-bestand, heeft aan kwaliteit ingeboet ten opzichte van het origineel, daar waar decompressie van het verliesvrije flac-formaat een exacte kopie oplevert van het originele bestand.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-2431253170791347324?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com1tag:blogger.com,1999:blog-18697195.post-37090950759404836672008-12-06T18:34:00.004+01:002008-12-06T18:39:37.207+01:00'took this picture moments ago in the Stadsfeestzaal in Antwerpen. <a href="http://en.wikipedia.org/wiki/Bryan_Berg">Bryan Berg</a> is trying to build the highest card house ever.

Some of those corrections require me to learn a bit more ;-)<br /><br />I've been teaching the <a href="http://www.linux-training.be/LinuxFun.pdf">Linux Fundamentals</a> four times since September and (partly) integrated my experience in the course to make the pace flow nicer between theory, demo's and practices.<br /><br />The thing is, I spent most of today (again) on the "first steps" chapter (pwd, cd, ...). I must not touch it again, unless for typo's! Other chapters require more urgent attention:<br />- I need to rewrite the two bash chapters, the first one is too long (imho it should be split in two separate chapters), the last one is way too brief.<br />- I also think the File System Hierarchy chapter is too long (too much theory compared to the humble practice)<br />- Processes is kinda complete, but the order and layout can improve (same for vi)<br />- Scripting is incomplete and also needs some order.<br />- The first chapter (introduction) is a mess. Luckily i teach it better than it is written.<br /><br />The <a href="http://www.linux-training.be/LinuxAdm.pdf">System Administration</a> course is in even worse shape. I'm really not happy about it. Okay, maybe the hard disk and LVM chapters are good enough, but kernel compile is really lousy. (I have completely rewritten the kernel compile chapter, but only in my mind, not yet on paper.)<br /><br />Anyway, thank you all for encouraging me and telling me it is a good book. No, this is not a plea for more pats on the back, just look at this post as my todo-list.<br /><br />I hope to have updated the bash chapters and the kernel compile chapter RSN.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-7039003356332572300?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-8097285009828519082008-11-14T14:34:00.005+01:002008-11-14T14:50:09.459+01:00Toen ik als klein manneke ne keer in de doos met doodsbeelekes mocht kijken, vond ik daar een mooi handgeschreven lijstje van namen. Het bleek een mini-stamboom van de <a href="http://www.cobbaut.be/stamboom/index.html">Cobbaut-en</a>. Ergens bovenaan stond mijn grootvader (Jozef Cobbaut), die toen al overleden was. Maar boven hem stond nog een naam: Carolus Ludovicus (ofte Charel) Cobbaut.<br /><br />Wow, dat was een man uit een ver verleden. Beeld u in als tienjarige, dat ge plots beseft dat uw stokoude (overleden) grootvader ook een vader had! Ne mens van voor er auto's waren, voor het bestaan van TV, algemene electriciteit en radio's! Die man was geboren in 1855...een mythische figuur.<br /><br />Gisteren fietste ik naar Merksem, naar mijn nonkel Jean Cobbaut en tante Irma (waarvan ik vroeger dacht dat ze Tantirma heette). En zij toonde mij een foto van deze Charel Cobbaut.

Of course not. Is a twittering plant a sign of automatic-twitter feeds for people ? I think so.<br /><br />In the future, when you go to a concert, a party or just get a hamburger, then auto-twitter-tweets (A.T.T.'s) will be twittering your every move. In the future, we are constantly tracked, monitored (and filmed?). So you can see which hamburger stand I prefer on Sundays, which parties I go to, and which concerts I attend. You can probably follow my gps coordinates, connect to live feeds of cameras close by, or even zoom in using the Google satellites(beta).<br /><br />When you buy a T-shirt at the CFC concert, then your followers would know what T-shirt you bought, how many people bought it, for what price and in which order. In this future the T-shirt sale generates more statistics than the average <a href="http://bvlg.blogspot.com/">bvl</a><a href="http://bvlg.blogspot.com/">g</a> post.<br /><br />In this future, there are no l33t blogging or twittering communities, since all this can be done automatically. (Also, it will be hard to differentiate between generated content and real content written by real people.)<br /><br />Parents can track their kids, banks their customers and lovers their lovers...it's going to be hard to surprise visit a friend, since they will mostly know where you are, with who, and what you are wearing, where you bought your clothes and for how much...must i go on ?<br /><br />But Paul, I don't want this future. I don't want my bank to track me (or my parents to know about my lover). Well, tough luck. When GSM's first arrived on the scene, many people claimed to "never want one". How many people do you know today that don't have a GSM ? How many below 60 ?<br /><br />Likewise, banks will not *force* you to be traceable *all* the time, but it will make your life a lot easier when you are. Same for cheaper insurance. Shops will not force you either, but fitting clothes and just walking out the store with them (with auto-payment when passing the door) is so much easier.<br /><strong><span style="font-weight: bold;"><br />freedom ?</span></strong><br /><br />Where is your freedom when you can be followed, tracked, monitored, located, contacted *all the time* ? Is this future avoidable ? Can <a href="http://en.wikipedia.org/wiki/Boiling_frog">frogs be boiled (read it if you don't know the story!)</a> ? That's the point, you don't see it happening.<br /><br />Remember end of the eighties ? We had movies on TV without advertising. Even the minutes before (speaker) and after (too late) the movie where without advertising. At that time we had a discussion in school about how movies in the United States where interrupted up to four times for advertising. Nobody would accept such a intrusive thing here in Belgium. But it came gradually, one (announced) interruption, then two... last time i saw a movie on TV, the sound of the advertisement was mixed in the movie fading to the ad. yuk!<br /><br />This is not a call for protest, it is only an observation... i could be wrong ;-)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-1561279367990237986?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com2tag:blogger.com,1999:blog-18697195.post-44809730006877267322008-11-04T21:58:00.000+01:002008-11-04T22:57:32.387+01:00<strong><span style="font-weight: bold;">part 2 of 3: dinosaurs</span></strong><br /><br />People that are not up to date with the latest technologies (or gadgets) are sometimes called<span style="text-decoration: underline;"> </span><a href="http://www.ondernemeringent.be/2008/10/hyperconnectivity.html">dinosaurs</a>.<br /><br /><br /><strong>twitter</strong><br /><br />In other words...some people <a href="http://geekandpoke.typepad.com/.shared/image.html?/photos/uncategorized/2008/08/15/minigeek19.jpg">twitter</a>, some people <a href="http://twitter.com/cobbaut">don't</a> ;-)<br /><br />By the way, to all my <a href="http://twitter.com/cobbaut/followers">twitter followers</a>, I promise to never twitter.

So to some people i am the opposite of a dinosaur.<br /><br />Is the gap between dinosaurs and the blogging/twittering/iphoning/secondliving online community widening ?<br /><br />(part 3 of 3 tomorrow)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-4480973000687726732?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com1tag:blogger.com,1999:blog-18697195.post-2182780274284436152008-11-02T12:27:00.012+01:002008-11-03T23:39:35.418+01:00<strong><span style="font-weight: bold;">Part 1 of 3: I was there!</span></strong><br /><strong><span style="font-weight: bold;"><br />Country Feedback Club</span></strong><br /><br />Thursday October 30th i went to the CD-release concert of the <a href="http://www.countryfeedbackclub.be/">Country Feedback Club</a> in Lille (Belgium!). The CD is good, the performance was good. Although i personally liked their <a href="http://cobbaut.blogspot.com/2008/10/country-feedback-club.html">acoustic setup two weeks ago in Antwerp</a> more. And even though these guys have a lot of experience, i prefer to hear Danny's voice from <a href="http://cobbaut.blogspot.com/2008/06/woodfever-in-den-hopsack-in-antwerpen.html">Woodfever</a> (provided they get <a href="http://www.tenderfeelings.be/index.php/paul/woodfever-in-kultuurk">their sound setup done</a>). Anyway, "i was there"!<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_ylVJKqjYoOw/SQ2UgncSCEI/AAAAAAAAAO0/0SaMyJ0-o1g/s1600-h/cfc.jpg"><img style="cursor: pointer; width: 400px; height: 213px;" src="http://4.bp.blogspot.com/_ylVJKqjYoOw/SQ2UgncSCEI/AAAAAAAAAO0/0SaMyJ0-o1g/s400/cfc.jpg" alt="" id="BLOGGER_PHOTO_ID_5264026827530307650" border="0" /></a><br /><br /><br /><strong><span style="font-weight: bold;">Moulin Rouge Party</span></strong><br /><br />Saturday November 1st i arrived on time for <a href="http://users.telenet.be/MisterB/MoulinRouge/">Moulin Rouge, the Birthday Party</a>. If you have seen <a href="http://www.imdb.com/title/tt0203009/">the movie with Nicole Kidman</a>, then you can imagine the dress code.<br /><br />(picture will follow <a href="http://en.wikipedia.org/wiki/Real_soon_now">RSN</a>)<br /><br /><br /><strong>Ten years Cuba Bella</strong><br /><br />Afterwards i went to the ten year <a href="http://www.cubabella.be/home-eng.htm">Cuba Bella</a> <a href="http://www.cubansalsa.be/cubansalsa/Fotokader.asp?event_id=1445">Salsa party</a>. I was really surprised by the (Belgian) Cuban group "Ache Havana" : An amazing life performance of ten musicians, packed together on an eight square meter podium. Damn these guys are good! Hm...was i there ?<br /><br /><br /><strong>I was there, or was i there ?</strong><br /><br />I also went to the market on Sunday, got a hamburger, went back to the "<a href="http://www.dezoltjes.be/">Zoltjes</a>" for some cake and stayed home for most of the afternoon. Really! Believe me! I blog it!<br /><br />(part 2 tomorrow...)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-218278027428443615?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com0tag:blogger.com,1999:blog-18697195.post-17106190279013920242008-10-25T20:50:00.003+02:002008-10-25T21:15:27.349+02:00Sinds bijna twee jaar geld er een algemeen rookverbod in restaurants. Iedereen weet dit, het verbod ook naleven blijkt voor sommige rokers moeilijk.<br /><br />Zo zag ik donderdagavond een ober roken achteraan in restaurant "Kapitein Zeppos" op het Mechelseplein in Antwerpen. Ik zei hem dat dit "degoutant" was (ok sorry, dat is misschien een aggressieve woordkeuze van mij), hij deed de sigaret wel onmiddellijk uit.<br /><br />Daarjuist, wederom helemaal achteraan in de "Kapitein Zeppos" een klant die rookte. Misschien heb ik weer iets te "aggressief" gevraagd om buiten te gaan, want hij begon me uit te dagen.<br /><br />Ik zei dat ik de politie zou bellen, waarop de roker me aanmoedigde om dat inderdaad te doen. Die politie laat uiteraard efkes op zich wachten, en ondertussen besloot ik onder invloed van mijn disgenoot om mijn excuses aan te bieden aan de roker (omdat ik overdreven reageerde op zijn sigaret). Toen de politie toekwam zei ik hen dan ook dat het in orde was, en een proces verbaal niet nodig was.<br /><br />Toen de tafel van de roker vertrok begon de uitdaging weer. Mijn disgenoot moest me weer tegenhouden, anders zou ik weer gebeld hebben...<br /><br />Soit, ik ben vaste klant in de "Zeppos", dus besloot me toch maar te excuseren aan de obers voor mijn gedrag. De obers van restaurant "Kapitein Zeppos" zijn bijna allemaal rokers, en geven toe dat ze soms binnen roken. Toen ik de rekening betaalde kreeg ik nog een sneer van de dame achter den toog.<br /><br />Eerlijk gezegd, ik heb geen zin meer om daar ooit nog een voet binnen te zetten. "Ga je je dan opsluiten?" vroeg mijn disgenoot. Tja, ik vrees inderdaad dat het zoiets wordt, want blijkbaar is de wereld nog steeds eigendom van de rokers.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-1710619027901392024?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com14tag:blogger.com,1999:blog-18697195.post-86759791856652705952008-10-19T00:17:00.003+02:002008-10-19T00:25:26.671+02:00Ne mens moet <a href="http://cobbaut.blogspot.com/2008/10/oudste-herinnering.html">zijn gedachten verzetten</a>, dus ben ik naar een optreden geweest van (den helft) van de <a href="http://www.countryfeedbackclub.be/">Country Feedback Club</a> in <a href="http://www.denhopsack.be/">den Hopsack</a> in Antwerpen.

Toen droeg mijn vader me binnen in het moederhuis. Daar lag een bedje, met op dat bedje twee blauwe autootjes. Eentje voor mij, en eentje voor <a href="http://cobbaut.blogspot.com/2008/08/belangrijke-beslissing.html">zus</a>. Ik wist toen niet wat <a href="http://cobbaut.blogspot.com/2008/08/belangrijke-beslissing.html">zus</a> betekende. Die blauwe autootjes hebben we nog vele jaren gehad, misschien liggen ze nog wel ergens in een doos.<br /><br />Zus is deze nacht overleden.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/18697195-2486688124472582984?l=cobbaut.blogspot.com' alt='' /></div>Paul Cobbauthttp://www.blogger.com/profile/12690770983694921987noreply@blogger.com8tag:blogger.com,1999:blog-18697195.post-61662159103526617272008-10-09T11:02:00.003+02:002008-10-09T11:10:04.612+02:00Two days ago, earth was hit by <a href="http://en.wikipedia.org/wiki/2008_TC3">a meteoroid</a>. So what ?<br /><br />This was the first time in human history that we knew a couple of days in advance that this meteor would hit our planet!
