Some More Bytes

Running away from my old host, which probably was the worst host EVER, I landed in this new server.

Let see if they can cope with a single blog!!.

I just released a new version of Powermizer Manager.

More details and downloads HERE.

Now that I am using a Windows Mobile based device, it is really annoying that the media player does not have a sleep timer included.  I noticed that many years ago in an iPaq PDA, and I see that nothing has changed.

When I go to sleep, I start the Windows Media Player usually with a large playlist, or even the loop function activated. I do not want, however, the device playing all night long wasting my battery… Well, it’s the very definition of Sleep Timer, ain’t it?

I put together a couple of lines of code, and made this **extremely basic** sleep timer. I did something similar many years ago for the iPaq, and now I’ve don it again. I spent more time trying to make the cab installer that the code itself:D. The code is almost worthless to put here, but I’ll do it just in case someone wants to modify it to start a different process other than the Media Player.

The “Suspend the device” function, calls the SetSystemPowerState API which according to the MSDN its effect may vary on each device, as it relies on some OEM power management implementation. It will not be necessary in most of modern devices, but I included it just in case.

GM750

My iPhone recently died due to a sudden deceleration against the floor.

Needing another phone while I decide which will be my next acquisition, I borrowed from my girlfriend a LG GM750 phone that she had lying around. This is a Windows Mobile 6.5 terminal and comes with the (sometimes annoying) S-Class interface from LG. It is not a super modern, super advance terminal, but it has the features I need: 3G which means web and mail, GPS and a nice battery. Add to this a couple of useful apps, and a GPS offline navigator and now you’re talking.And the best part, it was free!!.

Unfortunately there are not stable alternative roms for this model yet, so I had to change manually a couple of things that were making me unconfortable.

Well, actually this is not a post about how to update your netbook. It’s more about how to recover from a reboot when you shouldn’t have rebooted.

Instructions to update  are pretty clear in this post. However, avoid a reboot is not so simple as it seems. Every tutorial to update to 10.6.4 starts saying “Install 10.6.4 update, an before reboot…”. My problem is that I did it through the software updates, and it installed the actual update WHILE rebooting, so once installed and automatically rebooted, you’re sold. Probably with the combo update you are more lucky.

Or “How to develop for the iPhone under linux”.

If you have been looking for imformation about virtualizing LEopard or Snow Leopard, you’ll probably stumble upon this two sites, which contain most of the useful information. However, when it comes to Snow Leopard, information is spread across hundreds of posts, and most of it is for MS Windows only.

There’s another attempt using empire-efi here, which didn’t worked for me.

I just wrote a guide myself about how to get Snow Leopard working under Ubuntu 9.10 and Virtualbox 3.1.6r59338 and I was about to post it. However, I found another guide, for windows, which will work flawlessly under Linux with some minor tweaks, and has step-by-step screenshots, so I guess there’s no need to duplicate the content there.

Here’s exactly what I did to get things working:

This week KSplice published in his blog the second part of a interesting article, explaining the effect of a dangerus NULL derreference in the Linux Kernel. In the last year many of those holes were fixed in the kernel, so finding a true exploit wouldn’t be easy. It is still nice to understand how this kind of exploit works.

Here the first and second parts of the article.

Are you experiencing problems with the Subclipse plugin for eclipse? Well, I am too. The solution however, is pretty straighforward.

I’m using  a custom eclipse installation. The ubuntu repositories package is too old, so I always update my eclipse installation from the eclipse website. I install it to /opt/eclipse. If you’re using the default installation package, just look for yor install forlder, probably somewhere near /usr/share.

Now, I assume you installed the subclipse plugin, a nice SVN client. This client uses JavaHL libraries to communicate to the svn program istelf, and  unfortunately, this libraries installation is up to you. If you do not have them, subclipse will complain about missing libraries each time you need to do somthing svn-related. So, to fix if:

1. Install the javaHL libraries:
   sudo apt-get install libsvn-java
2. Tell eclipse where to look for them. Edit the file /opt/eclipse/eclipse.ini (or /your-eclipse-path/eclipse.ini), and locate the line:
   -vmargs
   Now just below this line, add the following one:
   -Djava.library.path=/usr/lib/jni
3. Happy coding!.

Browsing around I came across this post and loved it. This deserves as many copy-paste backups as possible, so here is one more:

People at Brown University have made some thought about redisigning the paradigm of modern IDEs. They came up with an interesting idea called Code Bubbles.

You can see Code Bubbles in action here. I think it’s an interesting approach, but I’m not sure how will this system behave while debuggin complex code. Maybe the cursor starts to move all over the virtual space…
