A while back i worked on a way to access VNC-sessions without requiring anything but a recent browser. This was just a proof-of-concept for a project that never went live. But it does work pretty good without bigger delays.

Today i finally went ahead and created a project on Google code for it. If you like check it out: http://code.google.com/p/viewncontrol/

After having spent some time working with Suns JAX-RS implementation Jersey and integrating RESTful-services in a few products i work on, i thought it might be a good idea to share my experiences.

So i decided to write a few blog-posts. I am not sure yet how many parts there will be, my current plan are 3. In this first part i want to talk about the "trivial" things. It took me some time to gather all the information i needed, especially the Maven artifacts to include were not obvious to me.

There seems to be some weird issues with f:param inside h:outputLink. The first issue is "&" in param-values not being properly escaped, leading to completely wrong values on the receiver side.
The second seems a little more complex. If the value contains "--" (2 dashes) only the text of the link will be written to the page (no a-tag whatsoever).

This is on Suns JSF RI. If anybody knows anything about these issues i'd appreciate to hear about it!

Hello Planet!!

If everything goes well, this should be my first post, that appears on planet kde! :-) I've started hacking on kde for last years edition of gsoc and have since tried to get multihead better supported.
In this post i wanna talk about what works and what's still missing, hope you enjoy!! ;-)

What do i mean when i say multihead??

To prevent confusion: i mean xrandr/xinerama/mergedfb-style setups, not separate x-displays on different monitors! I dont think there is anybody actively working on the latter in kde 4...

Another week, another release... This time for my very simple (aka feature-less) poker blinds timer!
I changed the artwork a little, but the main changes are making this actually work on smaller screens. It is now really usable on my K750i, so it might just be working on others as well.

As always, get it here: BlindsWatching! And if you like feel free to tell me, others or contribute! ;-)

Yes... Pretty useless! :-D

This now happened twice to me (the editor disappearing upon starting). There is no error or exception or the like displayed, its just gone. (and doesnt come back by selecting it from the menu either!)

The first time i mv'd my ~/.netbeans out of the way and redid all my settings, pretty annoying!

Now it just happened again and i didnt feel like doing that all over. Luckily mv'ing ~/.netbeans/6.1/config/Windows2Local/ away seems to do it! :-)

Well... I'm just wondering whether i should create a desktop-shortcut for that or if it'll be fixed anytime! ;-)

Migration always involves lots of work... And in the end things tend to break anyways! ;-)

So, sometimes it might be smart to accept a little overhead and just add to already running systems instead of redoing everything. This is one of those times!

I had to install Postfix on a customers mail-server which had previously been running qmail and vpopmail for virtual domains. The only bit of information i could find is this: http://www.inter7.com/vpopmail/postfix.txt

Since i wasnt completely satisfied with glassfish for some of my projects, i decided to try my luck with an embedded Tomcat.
This really seems to be an interesting way for some applications, while it sure isnt able to replace glassfish for more complex business-apps.

So...

Haven't really been working on the JSR-196 project of mine. Mostly because it's doing everything i need right now and nobody else complained! ;-)
But i decided that there might just be some folks who now more about build-systems than i do. So i figured it's time to see what they can do to help me out.

Thanks to Ron Monzillo i found out about JSR 196 and how its supposed to make custom authentication a lot easier in Glassfish. So i had a look at the specs and yes, it does exactly whats been missing before.

It wasnt that easy to find docs about some parts of it, but i might just not have looked at the right places. It was still fairly easy to migrate my existing code to this api and within just a few hours everything was running just fine! :-)

Update:

This patch has been integrated into vdr-mediad-0.1.0rc1. The rc has some other great new features, so go and get it here.

:-)

The OR22V is a RF remote (not infrared) that comes with an usb-stick as receiver. It is manufactured by X10. When plugged in to a computer with recent linux-kernel running, it should be detected by the ati_remote kernel module. So far so great!! ;-)

Now... Only every second key-press is recognized. And i mean exactly every second!! Digging into the source a little bit revealed, that some bits will be inverted on every second key-press.

Here's how i fixed it for me. Maybe somebody else has the same problem?!?!

II've recently started to work on some "real-life" projects in J2EE... All done using Netbeans and Glassfish!! And there is one thing which is usually kind of overlooked while planning an application... That is "easy" authentication!!

This might be setting a cookie to remember the user for next time or having links with one-time tickets sent by e-mail...

Now... This is of course pretty easy to do... Unless of course u still wanna use the container managed authentication/authorization!!
