More details at log4j-groovy Orfeus Simple & stupid music player plugin for Eclipse. More details at Orfeus page. Written just for fun in one evening. text/html 2008-09-05T18:41:04+02:00 Jan Kotek http://www.kotek.net/blog/writing_fast_nio_webserver?rev=1220632864&do=diff I wrote fast and simple web server using New I/O and Kilim microthreads. No locks, no blocking, no channel selector. With a few optimalization tricks, it is propably fastest webserver written in Java. Channel selector problems NIO is using channel selector as mechanism to dispatch events. It is promoted by Sun, and nearly all NIO based programs are using it. Good tutorial is here. text/html 2008-08-29T17:48:51+02:00 Jan Kotek http://www.kotek.net/asynchttpd?rev=1220024931&do=diff Is web server without any locks and synchronizations. Is written in pure Java, uses NIO nonblocking channels and Kilim lightweight threads. Is designed to handle MANY concurrent connections, internally can handle 100 000! connections simultaneously. And everything with a few threads and small memory requirements. text/html 2008-07-25T15:01:38+02:00 Jan Kotek http://www.kotek.net/blog/changes?rev=1216990898&do=diff Recently I made a lot of changes in OpenCoeli: * OC is now vector based, it is more flexible. * much more simplified, no ClassMapping, no AdapterFactoryes, no multiple connection handlers * no RCP framework, OC was using Spring RCP, then Netbeans Platform, then JDAF.. it is overkill for one-man project. Just plain swing. * features driven, features are more important then theoretically clean code. * command line for everything, CLI is simply more important then GUI (but GUI remains) … text/html 2008-07-10T16:44:27+02:00 Jan Kotek http://www.kotek.net/blog/new_color_scheme?rev=1215701067&do=diff OpenCoeli have new color scheme, inspired by astronomy.com maps. It is “white on dark blue”, something like theme of this web page. Blue rectangles are background brightness calculated from USNOA catalog. There are problems with label. Some screenshots: text/html 2008-07-06T21:29:04+02:00 Jan Kotek http://www.kotek.net/blog/astrogrid_in_troubles?rev=1215372544&do=diff It looks like AstroGrid have troubles with money. It is very bad news, AstroGrid is one from very a few curently active software project for Virtual Observatory. text/html 2008-06-17T01:28:58+02:00 Jan Kotek http://www.kotek.net/blog/some_frustration?rev=1213658938&do=diff Written in deep night after a few beers, contains grammar mistakes, don't take too seriosly. Development on OpenCoeli have reached something which I call 'frustration point'. Now all fun is gone and only painful development is remaining. When someone ask how OpenCoeli is going I say 'slowly and painfully'. text/html 2008-05-22T14:33:26+02:00 Jan Kotek http://www.kotek.net/opencoeli/download?rev=1211459606&do=diff There is no download yet. It will run on any platform. Only one dependencie is JRE 1.5 or better. Launcher are batch files in root directory, on Unix you need to set exec bit. You can get source for this milestone from SVN under branch Milestone 4. See Getting started text/html 2008-05-08T18:29:32+02:00 Jan Kotek http://www.kotek.net/opencoeli?rev=1210264172&do=diff OpenCoeli [ce:li] is free open source (GPLv2) software for amateur astronomers. It is fresh new software based on recent technologies. OpenCoeli is nice introduction for serious amateurs to modern astronomy. It is under development, so features described on this page are just planned.
