writing an good press release example from lulu.com
http://www.lulu.com/en/services/marketing/index.php

and they are using bitweaver

Seems that for an romanian firebird sites the cms list would be :bitweaver, drupal , typo3 , wordpress

I don't like the software that doesn't write to an data abstraction layer like
phpado http://adodb.sourceforge.net/
or mdb2
thinking loudly - FreePascal and Fastcgi

Morfik is precompiling the application into an cgi using pascal (fpc)
I was thinking what if the fastcgi can be used to run an pascal program precompiled with lazarus(fpc)


The main issue is that main scripting languages migrate to fastcgi: php , python, perl
and light httpd servers (nginix,lighttpd,apache+fastcgi module)

Why they migrate ? because apache threading doesn't work for scripts and we are back to cgi and share nothing architecture (kiss philosophy )

Your favorite language sucks

The other day I posted a link to an article by Ted Neward called "Can Dynamic Languages Scale?" I thought it was interesting to see that an outsider saw the potential in Parrot, even though it's not at 1.0 yet. As an afterthought, I lamented that he made a dig at Perl at the end, smiley face or not

Via launches 64-bit architecture

Via has unveiled a 64-bit, VM-enabled x86-compatible chip architecture for green PCs, home servers, and mobile devices. Chips based on the "Isaiah" architecture promise to outperform Via's current C7/Eden chips two-to-three times, within the same power envelope.

streaming with vlc and leadtek winfast 2000 xp global

encoding server ---> upd stream ---> streaming server (listen on 1212 port)



i assume the card is installed we will need to use the /dev/video0 interface and stream from it in mpeg4 or

On the streaming server or computer i do
vlc udp:@:1212 and i listen to the port (later i will do an relay to the stream and send it to the clients)

On the encoder server:
Here is how i do the encoding from the command line (and i send the stream to the 192.168.0.1:1212 server)

vlc -vvv --color v4l:/dev/video0 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}:std{access=udp,mux=ts,dst=192.168.0.1:1212}' --ttl 12


Parrot 0.5.2 released, now with "make perl6"

[from the cromatic blog: First, weve managed to bundle up Patrick Michauds Rakudo (thats the implementation of Perl 6 on Parrot) such that you can type make perl6 on Unixy platforms and make perl6.exe on Windows and get a working standalone Perl 6 binary. This is experimental and we hope to iron out some installation and deployment issues by next months release, but it was important to demonstrate our progress. ]
