Fix slow Windows 7

  1. Create a bootable Xubuntu USB installer. You can follow these instructions. Latest version recommended.
  2. Stick the USB in the computer, reboot, and on the BIOS, select the USB as boot drive with priority over the hard disk.
  3. On the Xubuntu installer, follow the steps to replace Windows 7 by Xubuntu.
  4. Once booted up and logged in, run these commands on a terminal:
    1. sudo apt-get remove abiword gnumeric gmusicbrowser
    2. sudo add-apt-repository ppa:libreoffice/ppa
    3. sudo apt-get update
    4. sudo apt-get install libreoffice vlc
  5. Optional: if it is the computer of a friend, amaze him/her by telling that there are no viruses an no antivirus is needed
  6. Open Firefox and install Adblock Plus.
  7. Enjoy for many years without virus nor performance drop!

Predictions 2014

Retrospective of predictions 2013:

Chrome hará un 95 % en el HTML5 test. Firefox menos.

Uishh almost. Current Chrome is 91 % and Firefox is 80 %.

El share en desktop Chrome/IE/Firefox será 40/30/20.

No but close. IE is below expected thanks to Safari keeping the pace and Chrome pushing harder.

- Saldrá Firefox OS, funcionará en móviles de 150 euros, será la plataforma con menor coste de desarrollo marginal y deployment para el 90 % de las aplicaciones móviles, pero no llegará a los targets porque Telefónica no hará la correspondiente inversión en marketing, porque... - No más del 50 % de las aplicaciones que interesan a los targets tendrá versión "compatible con Firefox OS" (o sea, HTML5). - Saldrá un listo que inventará una palabra moderna para One Web. Los empresaurios oirán la palabra en alguna conversación y empezarán a decir que ellos "ya lo hacen", provocando el punto anterior.

Hmmm I am pretty impressed of how Telefonica is marketing Firefox OS. Is like they are doing that for real.

It is the first prepaid phone they offer as of today, and the "more info" page offers a quite friendly and useful video about its basic setup and usage.

Sadly they are out of stock. I guess that that is a good sign though!

Los targets seguirán comprándose móviles de 600 euros y pagando tarifas de 600 euros al año porque "necesitan movilidad", pero seguirán rechazando Google Drive para trabajar porque "no es seguro".

Regarding the 600 euros, I can understand because they are already using quite more their phone than their computer - so it makes total sense to spend more in the first one. And regarding Google Drive, well, turns out that mostly any guy with a federal badge in the United States can peek at everything you do on the Internet - so I quite understand this one as well.

And now predictions 2014

  1. My mother will master Ubuntu 12.04 - a very cheap OS (free on acquisition, very low maintenance cost) that allows you to focus on web browsing (instead of avoiding crapware, managing updates, and reinstalling things because malware ruined them).
  2. Firefox OS will get a ridiculous but historical 2% of share among web users, and I will buy one.
  3. Internet Explorer 9- will only matter if you are addressing hardcore dinosaurs. Hopefully jQuery guys will realize of this and will release a half-sized version of jQuery named jQuery 3, that I will not use anyway.
  4. The only remaining mainstream usage for desktop applications will be accessing USB devices. The rest of the mainstream things will be done through the web. asm.js' utopic but real 1.5x slower than native speed will be a big factor.
  5. Linux will take over the desktop. Joke!

Android 4.4 has a real browser, but it won't matter for two years

Finally the Android browser scores something decent on the HTML5test.

The reason is luckily not a reinvention of the wheel but the use of Chromium as base for it.

However, given the crappy upgrade policy reality of Android, this improvement is going to result irrelevant for at least the next two years. The quota of incapable Androids will be, in the meanwhile, still too big.

Users not wanting to spend 600 USD/EUR/something to have a fast, capable, respectful browser are encouraged to use Firefox for Android.

Buyers of new phones not wanting to face the same problem in the future are encouraged to buy a Firefox OS phone.

Reset sound configuration on Ubuntu

I tried to install a sound equalizer on Ubuntu and ended up without sound equalizer, and also without sound. Classic Linux mess. To fix this and other similar problems run the following command.

alsactl init

LibreOffice has to fix its presence on distros

Something that LibreOffice has to fix is its presence on distros.

Is close to value-less that you don't get LibreOffice upgrades if you don't upgrade your distro.

I use Ubuntu 12.04 based distros at home and at work, and I plan to keep doing that at least until May 2014.

Xubuntu 12.04

They just work, and they work fast.

They don't give me problems because Ubuntu 12.04 is the Linux distro developers look at when they do develop. It has been like so since a year ago, and it is going to be so for the next year at least.

But LibreOffice 3.5 is a piece of shit. Relatively at least.

Why do I have to miss all the new love that the community put in LibreOffice 4.1?

LibreOffice 4.1

Why will I have to miss it again for LibreOffice 4.2?

Early preview of LibreOffice 4.2

If Ubuntu 12.04 can receive Firefox upgrades each 6 weeks, for sure it can receive LibreOffice upgrades each 6 months.

So, gals and guys: Let's do it!

Using the discrete GPU on Ubuntu

The following might be interesting for you if you match the following:

  • You have a CPU with integrated graphics
  • You have a discrete GPU that your Ubuntu (or Ubuntu-based distro) does not use
  • You need those goddamn extra FPS now!

Open a console, secure the perimeter of your modem/router whatever, and enter the following commands.

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install linux-source linux-headers-generic sudo apt-get install bumblebee bumblebee-nvidia


optirun firefox

With that, Firefox will use your discrete GPU instead of your integrated graphics. The WebGL Aquarium benchmark should run like 10 times faster.

You should also be able to run other programs besides Firefox using this "optirun" command, of course. For example Kerbal Space Program, with something like the following.

LC_ALL=C optirun "/opt/software/SteamLibrary/SteamApps/common/Kerbal Space Program/KSP.x86"

Note that that "LC_ALL=C" is some kind of magic fix for multiple issues for Kerbal on Linux; I'm not explaining what it does here (neither I know, if you ask).
