October 13, 2006 WikiPlot stable release (1.0.0)
Today, we have released WikiPlot 1.0.0, we consider it relatively stable. As you might know WikiPlot is a part of a project me and some of my mates have been doing in our programming lessons. Well today, it was quiet stable and we had to hand in our project, so it was hard to find a better day to call it final release 🙂
To someone this might seem like we pushed a little early release, because of our deadline. Well it’s most likely true, perhaps it should just have been a beta release. But when Novel van call OpenSuSE 10.1 a final release, then why can’t we 🙂
Anyway, we will of couse be bug fixing, but I don’t expect to find at lot of them… If you find any please report to our issue tracker…
October 12, 2006 On-the-fly plotting with PlotClass
 In the development of WikiPlot, which is getting really close to a release, we have written some classe for plotting mathematical expressions using php. Now I have finally be able to relase a public test version of the plotting class:
Jopsen.dk/plot/expression
Where expression is a mathematical expression, like 2x^2+4sin(3x) or what ever sick expression you may find 🙂
Anyway it’s the internal plotting class for WikiPlot, and you can try out…
October 8, 2006 Last.fm, Amarok og firefox
 I gÃ¥r da jeg var ved at rediscover my music med Amarok, faldt jeg over last.fm, en online radio station der tilpasser sig efter din musik smag! GÃ¥ online register en bruger og begynd at lytte til online radio, nÃ¥r der kommer et dÃ¥rligt nummer trykker du bare “skip”, du kan ogsÃ¥ rate nummerne positivt eller negativt alt efter om du kan lide dem. Der er ogsÃ¥ mange flere funktioner pÃ¥ last.fm, grupper, forum, charts og listen er meget langt.
NÃ¥r ja, nÃ¥r man har oprette sig kan man lige join Amarok bruger gruppen selvfølgelig 🙂 Amarok er integreret med last.fm, sÃ¥ du skal bare indtaste brugernavn og adgangskode, ogsÃ¥ er du ellers godt igang…
Desuden kan man registrer protokollen lastfm:// i firefox, sådan at når man surfer lidt rundt på http://last.fm kan man bare klikke på at linke og så kører radio stationen i Amarok:
- Ã…ben Firefox
- Skriv about:config i adresse linjen
- Højre klik tilføj streng
- Streng navn:network.protocol-handler.app.lastfm
- Streng værdi: amarok
OgsÃ¥ surfer man bare rundt pÃ¥ last.fm og finder nogle spændede radio stationer…
Hvis man subscriber kan man oprette sine egen personlige radio station, det lyder totalt nice, nu slipper jeg da endelig for at finde pÃ¥ en musik smag… Men last.fm kommer jeg jo nærmest sovende til en 🙂
September 11, 2006 MonoDevelop 0.12 Released
A few days ago I saw that, the new MonoDevelop 0.12 has been released. It features many new features most amazing one of those is deployments system, to generate tarballs with autotools support. And ofcause improvments on the GTK# designer…
Perhaps I don’t have to install a virtual Windows machine as development platform, it seams as MonoDevelop might replace SharpDevelop. But it’ll properbly be some time before I’ll find time to install and try it… Maybe there’s some future P2PChat here 🙂 I’ve been doing some development on P2PChat in the summer, but they never became stable and I never commited them.
But autotools intergration is definitively nice, and will help me push some more beautiful releases…

September 7, 2006 The Not So Short Introduction to LaTeX
 For godt et halvt Ã¥rs tid siden, installerede jeg LaTeX pÃ¥ min wiki. Jeg lærte hurtigt grundlæggende LaTeX kommandoer til lave simple formler. Forleden da jeg kiggede lidt pÃ¥ det folk kalder internettet, faldt jeg sÃ¥ over en bog der hed: “The Not So Short Introduction to LaTeX“. Nu har jeg sÃ¥ tygget mig igennem det meste af den, og den kan klart anbefales.
Bogen giver en god start på LaTeX til andet end bare formler. Og selvom LaTeX er gammelt, til tider en smule besværligt, er det et godt system at skrive afleveringer i. Bogen er ikke en total gennem gang af LaTeX, og man mangler stadig nogle enkelte ting for at kunne skrive avancerede matrix notationer. Men den giver en god start og man får godt fat i konceptet, man kan også læse den forholdsvis hurtigt, ca. 2-3 timer.
SÃ¥ hvis du gÃ¥r med en lille drøm om at lære LaTeX sÃ¥ kan “The Not So Short Introduction to LaTeX” downloades frit fra: http://www.ctan.org/tex-archive/info/lshort/english/
September 1, 2006 WikiPlot Import to SVN
Today I imported WikiPlot to Google Code‘s SVN repository, and there by officially started the project. WikiPlot is a plotting extension for MediaWiki, written in php. It isn’t all done yet, but the php plotting class is getting stable. After that the plan is to write an interface to MediaWiki and catching functionality. The project is hosted at Google Code hosting, because they offer a simple solution with SVN. I experience with SourceForge and it is indeed a good hosting solution. But I thought our project was too small and would fit better in at Google Code.
It all started, this year when I started having lessons in programming at school, since me and some other “geeks” knows a “little” more about php/programming, then they were teaching, the teacher wouldn’t force us follow their basic programming course, which is what they are doing in the start. Anyway the teacher didn’t care about what we were doing as long as it was in php. And since I kind of need a plotting feature for my wiki, I thought it would be a nice project. So me and some of the other guy’s started developing WikiPlot.
Since I haven’t had time to create a homepage for WikiPlot, you can follow the development from this blog (See categories). I’m properly going to make the WikiPlot homepage a part of my homepage once it’s implemented and stable. Feel free to contact me if you have any questions.
August 23, 2006 Ny mobil – GCalSync
 Så har jeg endelig fået mig en ny mobiltelefon, min gamle 3510 var ved at være lidt slidt. I dag har jeg nemlig købt en Nokia 6131, det er en lille fin klap telefon med 1,3M pixel kamera. Med det hele, jeg har lige bestilt et 1 GiB MicroSD card til den, så jeg har noget plads at gøre med.
Jeg har også forsøgt at kører GCalSync op på den, GCalSync er et Java (J2ME) program til at synkronisere mobiltelefonens kalender med Google Calendar. Desvære har GCalSync nogle problemer med understøttelsen for Symbian series 40, hvilket betyder at det ikke er lykkes mig at logge ind og benytte GData API til syncronisering. Men GCalSync kan heldigvis benytte både public og private xml-feed, fra Google Calendar.
Det er forholdsvist nemt, man skal bare lige vide hvordan man gør. Hvis ikke du kan fÃ¥ din mobil til at logge ind pÃ¥ GData API, med dit brugernavn og adgangskode. Skal du istedet slette brugernavn og adgangskode fra instillingerne i GCalSync og skrive adresse til dit private Google Calendar feed. Denne adresse ender pÃ¥ “basic”, der skal istedet stÃ¥ “full” ellers gÃ¥r der noget galt med datoer og tidspunkter (Hvis du har andre problemer sÃ¥ kig pÃ¥ Google Groups).
August 15, 2006 Tilbage til Ubuntu
I dag skiftede jeg tilbage til Ubuntu. Jeg har tidligere kørt OpenSuSE 10/10.1 og endnu før det legede jeg med Ubuntu 4.10.
Efter en hel del problemer med pakkehåndteringen, YaST og en masse andre ting i OpenSuSE 10.1 valgte jeg at skifte tilbage til Ubuntu. Nu har jeg så installeret Ubuntu 6.06 og den kan varmt anbefales! Det eneste negative ved Ubuntu er alt den software der skal efter installeres, men med Synaptic/apt-get er det ikke et realt problem.
Det eneste tidspunkt jeg har været nød til at redigere config-filer var ved installationen og opsætning af network-manager. Ubuntu trådløs netværk virkede også fint uden network-manager, men det tog lang tid at skift mellem forskellige netværk.
August 4, 2006 Toshiba reperation
 Nu er det efterhÃ¥nden et Ã¥r side jeg købte min Toshiba Tecra A3, og tastaturet har altid sagt nogle sjove lyde… Men lige pludseligt sagde det helt stop, og flere af tasterne holdt op med at virke. SÃ¥ jeg sendte min bærbar til reperation hos toshiba’s support udbydere i Danmark: Service Gruppen. Og meget kan man sige om min bærbar, men supporten var upÃ¥klagelig… Jeg sendte den afsted mandag og fik den hjem Torsdag, men et nyt tastatur. Hurtigt og smertefrit, sÃ¥dan skal det være…
July 23, 2006 Open Source Development with CVS
 “Open Source Development with CVS” is a book from cvsbook.red-bean.com released under GNU GPL. I’ve been reading most of the CVS related capters, and it’s certainly a good start if you wish to use CVS. It’s a long book, and it takes you far beyond basic CVS commands. But it was also a good book, and for a person who has never used CVS before it was a good start. I can recommand it to anyone who wants to learn CVS, but you might want to skip a few capters, there’s a lot about develpment communities, which is not necessary to know if you just want to learn CVS. I feel a bit more confident using CVS for the next changes to P2PChat.
