Carlos sent me this picture of a sign he found in downtown Curitiba (at Vicente Machado street).

I got myself a guitar a long time ago in the hopes that I would someday learn how to play it, but it stayed in its case for years. Until now — after hearing Santiago talking about guitars all day for weeks (and even Miura telling how much fun he had with Wii Music) I decided to give it a try. Using the method from the Guitar Hero School of Music, I just picked up a tune that sounded easy enough — the Munsters TV series theme — and tried to match the notes with little knowledge and awful technique. My version is a mix of the first season, second season and Straitjackets versions of the theme, with some lines of cheesy Spanish dub from an episode and island mallets throwed in just for fun. Together with the bad guitar playing, this is guaranteed to make Jack Marshall spin in his grave, so my apologies in advance. Old stuff not announced before: these are a couple of small and simple GTK+ tray applications to help hobbyists installing alternative operating systems in the Eeepc and similar netbooks to show capslock or numlock status (in case the hardware lacks the appropriate LEDs) or to logout or shutdown from GUI if you’re running finit with a light desktop environment. Get the code from the git repository with git clone http://helllabs.org/git/tray.git. (You may also be interested in Metalshark’s kbdstatus, which a Xlib-based version of the original Eeepc keyboardstatus application.)
You’ll need to supply a shutdown helper script and allow it to send signals to the init process if executed from the console (registering it with pam_console, for example). The applications are GPLed, so please consider contributing back your enhancements, fixes and changes. The traditional method of dealing with filesystem images is to mount them as loopback devices, and that is a simple, elegant and universal way to change its contents in any way you feel fit. It has the disadvantage, however, of requiring superuser privileges — which you may not have in every host you frequent, or you wisely don’t wish to grant to anyone using your machine to develop filesystem images. Christian Hohnstädt’s e2fsimage solves the problem allowing one to copy an entire subtree into a image file, but what if you want to extract, examine or manipulate arbitrary content? Strange things you do amidst a depressive crisis when you brain doesn’t act quite the way it should act under normal circumstances.
No, I am your father is so lame. Green tea is much better. “What is nash-hotplug and why is it consuming 100% CPU?“, someone asked in a Xen-related message I found after experiencing similar problems booting Mandriva 2008.1 with finit in the Asus Eeepc. This situation seems to be especially common in different Linux distributions running as Xen guests and the usual advice is to just kill nash-plugin after the system boots. Instead of doing that ugly workaround, we decided to investigate and find out what’s happening. Whatever nash-hotplug is supposed to do, I can’t say it keeps running consuming 100% of your cpu because it’s a well-written program (notice the bizarre IPC protocol, how it tries to read from a descriptor after closing it and how easily it can get trapped in infinite loops). Use the following quick fix to avoid the problem. Die, nash, die. Há algum tempo um banco passou a utilizar um sistema de verificação do computador do qual é realizado o acesso a seu sistema de internet banking, oferecendo suporte a diferentes sistemas operacionais incluindo Linux. O funcionamento desse sistema pode ser facilmente inferido com base nas chamadas feitas pela biblioteca de autenticação, dos símbolos públicos disponíveis e um pouco de dedução. O método utilizado é surpreendentemente simples tanto em conceito como em implementação; a descrição a seguir, obtida de uma breve análise das chamadas e símbolos disponíveis, pode ser de interesse dos usuários do sistema que desejem saber mais sobre os dados que são coletados de seus computadores. Having read the (not so enthusiastic) reviews of the first Cloudbook users, it seems that most software-related complaints of early Cloudbookers revolve around screen resolution, wifi performance and slow boot. While I offer no ready-to-use solution for these problems, here are some pointers that could help hobbyists or desperate users:
On a side note, finit-alt worked quite well booting Mandriva 2008 with Enlightenment in the Dreambook IL1, another VIA-based mini-laptop (possibly booting even faster than the Eeepc because the Intel driver for Xorg takes a while to initialize). While I was updating the fastinit reimplementation with Metalshark’s patches, rallying enthusiast and Eeepc owner Ednilson Miura pointed me to a discussion in EeeUser about increasing screen resolution of the Eeepc display, basically by scaling down a higher resolution desktop to the native 800×480 Eeepc display. We’ve seen different approaches to solve the low resolution problem, from the traditional viewport to a larger virtual desktop to real screen rescaling (Intel has a driver-based rescaler for its Classmate PC, and there are similar resampling technologies used in other manufacturers with Eeepc-similar offerings usually with quality ranging from barely readable to unreadable). The aforementioned discussion presents a somewhat novel approach: a VNC connection to the local host. I think we could get a similar effect with a more elegant and less resource-intensive solution: X compositing. It would also be one of the first non-frivolous utilities for desktop compositing, previously used almost only for eye-candy. RandR and driver-based rescaling approaches are also discussed below. |
