RPM Packages: Compilation flags
Since October last year I took over the server management tasks in my project. Unfortunately, those machines are loaded not with Debian but with Scientific Linux (Why SL is one of the great mysteries of universe).
One of these days I needed to know which were the compilation flags of a package.
TL;DR:
rpm -q --queryformat="%{NAME}: %{OPTFLAGS}\n" PACKAGE_NAME
Long Version:

Exchanging your notebook LCD screen in Japan
This is the second time I break the screen of a notebook.
First time was with this this Asus Eee PC 1000HE I had for a 1 year and a half. The little boy was on beside my bed and so it had an encounter with my foot, long enough just to crack the LCD screen. The second time was a few weeks ago. I was doing some work on the bed before sleeping but I actually fell asleep. The notebook just fell. Here...

Dynamically adding attribute accessors in Ruby
A simple way for adding attribute accessors to a class dynamically:
class MyClass
def add_attr(name, value)
self.class.send(:attr_accessor, name)
instance_variable_set("@#{name}", value)
end
end
just call the add_attr method passing the name of the accessor (as a string) and a value that will be assigned to the variable.
You can also turn this in to a module so that you can easily...

Fixing garbage text on terminal on Linux and Mac
Sometimes you just happen to cat a binary file and it just messes up your terminal output and all can see and type is garbage.
Normally here you’d just give up and reopen your terminal but here’s another solution: Just type the command below:
echo -e \\033c
All you’re doing is sending an ESC(033 is the octal version of the ASCII control key “ESC”) + a letter...

Fibonnaci closure in Go
I’m trying to finish the Go Tour and one of the exercises was to write a Fibonnaci closure, that is, a closure that generates the Fibonnaci sequence.
It was a cool exercise to learn on closure works in Go, so to remind myself of this later, I’ll share it here:

plist2ota - Generate OTA Manifests from plists
A friend of mine was in need of a script to automatically generate the OTA Manifests needed to distribute iOS apps internally through the iOS Developer Enterprise License.
So I wrote a little Ruby script that uses the plist gem for creating a Ruby Array from the plists information. One limitation I found in the plist gem is that it can’t parse binary plists. Right now I’m working on...

CommandT and Ctrl+S on Mac OS X
One of the best plugins I’ve found for vim is CommandT. It lets you open files in a very speedy and intuitive way, making it very simple to search files and open them in tabs, splits or vertical splits. Or so it should be. On OS X, opening a file on a new split doesn’t really work. You should be able to do it using the Ctrl-S shorcut but it just doesn’t work.
Today I decided to...

In the end, it's all about DNA
Today, I want to talk about company culture, and the best analogy I could find was a child. So bear with me until the end and let’s us not deviate into the field of children psychology.
They way a child is raised by its parents is very important and decisive in its future. Children tend to take in account their parents tastes and way of thinking when molding their own and most of the we can...

Code of the day: Circular shift for integers...
“x” is the number you want to rotate. “n” is the number of rotations you want to apply.
While writing this I actually felt how slow python’s math lib is. I’ve wrote this a while ago, but iirc a version I wrote using string operations was actually faster than this.
I managed to get to a pretty fast version later on but it involves caching all functions in local...

I'm back! and Let's talk about Rails
For some reason lately I don’t feel as productive as before. For some reason I don’t feel as motivated as before.
I’ve been giving some thought to that and I guess it’s because I haven’t spoken out loud about the stuff I’ve been doi.ng.
I’m gonna keep this rant short so I get to the point.
I plan on writing something on this blog every day.Yes. Every...

A new resolution: No more 32 bit software for me.
10 years ago, when I started dabbling with linux and later decided to make it my main environment, there were things from the Windows world that I couldn’t let go. Be it games, tools, services. I would spend hours and hours trying to get Wine to work and to run those things I could’nt live without. Until one day I realized that…I could live without them. Since that day I decided...

Maximizing and restoring panes in tmux
Recently I gave up on screen for tmux. From the tmux homepage:
tmux is a terminal multiplexer: it enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.
Tmux is screen on steroids. You can customize just...

Fixing no sound in browser problem on Linux
On my last post I talked about fixing and tweaking stuff on my Linux machine and about the things that still need fixing.
Right after I posted that I actually found the solution to my problem of having no sound in the browser and I’d like to share that with you.

Fixing and tweaking
After a very very long time, I’ve decided to take some time to fix and tweak stuff on my machine.
For those who don’t know I’m a Slackware user. I’ve been using Slackware as my main system for almost 10 years now and I’m very happy with the distribution. It’s very lean and stable and it has the right mix between stability and recent packages apart from giving...

This is Android - for the best or the worst
The R.style reference, however, is not well documented and does not thoroughly describe the styles, so viewing the actual source code for these styles and themes will give you a better understanding of what style properties each one provides.

Do we need a new QT based Desktop Environment?
I’ve been using linux for quite a while now (10 years that it has become my main OS and 9 as my only OS*) so I think I’ve had my share of Linux GUIs. Gnome, KDE, fvwm2, Xfce, fluxbox, blackbox, WMaker, Enlightenment…
No matter what I try, though, I always end up going back to KDE. I kinda like how things work but mostly because I like Qt. However most wouldn’t say KDE is a...

Today, after getting my netbook reinstalled I decided to write about my history with linux and how things changed from back then. Hope you enjoy it.
My first contact with linux was Slackware 3.6 by the end of 1999.

A tale of Japanese support on vim
TL;DR:
add “set fileencodings=iso-2022-jp,euc-jp,cp932,utf8,default,latin1” to your ~/.vimrc and use “:e ++enc=<encoding_name>” to reload a buffer with a specific encoding.
The fun, instructive (and long) version:
I work for a japanese company in Tokyo and working a japanese language environment, with japanese comments in the source code is something you get used...

Patching 802.11 Linux STA driver for Kernel 2.6.37

After upgrading the eclipse packages I was surprised that I couldn’t export an app to apk after the upgrade.The problem was that I hadn’t upgraded the SDK packages, including the platform tools. It’s seems that the new ADT plugin is...

Steve Jobs
Even though I never had the honor of meeting Steve Jobs in person, I’d like to think I’m blessed for having the opportunity of living in the time as a visionary as him.
His influence was (and still is) not restricted to those around him, his vision and his achievements inspire, instigate and push forward an unthinkable number of people who are also fighting for their dream, hoping...

Netflix CEO Reed Hastings first apologizes for a lack of communication, and then gives his thoughts about the recent price changes and separation of DVDs and streaming (which is still the right move, as Hastings reiterates).
The wording is good. Amazingly, it doesn’t sound like the total bullshit you usually read in such posts. But here’s my favorite part:

laptop
Even though it’s only been a couple months I gotta get a new laptop. I definitely need one of those new ultrabook things Intel is betting on or a Macbook Air. The one I have right now is nice and fast and the most important: it’s battery last centuries but I can’t deal with it’s size anymore. After getting used to my last 1.05Kg Acer I can’t deal with 1.5Kg Dell...
