Análisis/review de varios headsets para jugar y solución con kit artesanal (ACTUALIZADO ENERO 2013)

Spelling in Vim

Since version 7.0 Vim includes a spelling corrector without the need of installing any plugins. The usage is pretty simple once you have configured some shortcuts in your vimrc, for example I have:

nmap  :setlocal spell spelllang=en_en<cr>
nmap  :setlocal spell spelllang=es_es<cr>

This makes the spelling correction to start when I press Control+s (for Spanish) or Control+g (for English). If this is the first time you enable spelling for some language, it will download a dictionary.

If we use gVim, the spelling marks errors with a little curved underline like word processors (in text mode it will change the background color of the mispelled words). Also like in word processors, the spelling works in real time once enabled.

Some common spelling commands:

  • zg: add the word under the cursor to the dictionary
  • [s y ]s: move to next/previous spelling error
  • z= : show spelling suggestions for the word under the cursor

We can see all the commands with “:help spell”. To disable spelling we write “:set nospell”.

Battlefield 3 beta for PS3 quick impressions

So, I got to play some hours of Battlefield 3 beta for the PS3 yesterday.

Quick impressions:

What I liked:

  • The sound is awesome
  • The realistic weapon recoil
  • The Metro map is beautiful
  • The rush gamemode made for some exciting playing
  • The PS3 graphics are fine (better than COD), but not up to the hype
  • The control is better than Bad Company 2

What I didn’t like:

  • EVERY SINGLE TIME that I made a squad with two friends, it splitted it when joining a game. Sometimes even on opposing teams.
  • We couldn’t manage to get the voicechat to work the few times that it put two of us in the same squad. Extremely annoying.
  • Bugs, bugs, bugs. Spawn trapped in the ground, see everything in blue or purple hues, color “flashes”, suddendly you couldn’t aim or run, etc, etc, etc…
  • The PS3 graphics are fine (better than COD), but not up to the hype.
  • Only one map (Metro) and one gamemode (Rush). No conquest, no vehicles. If EA is releasing the beta with the hope of convincing undecided some players to buy the game, they’re doing it wrong.
  • Too many COD-style players trying to run into the objectives alone or completely ignoring it, without waiting for the squad mates to spawn around. Nobody tagged the enemies.
  • The controls are not as direct and fast as COD.


If they fix all the bugs it can be a fun game to play. But it won’t dethrone COD on copies sold yet.

A hint for Android smartphone makers

Almost every day on my Google Reader’s collection of feeds I read rumors or facts about new Android handsets. Almost always the things have a ridiculous amount of CPU power (for a phone) more RAM memory and higher resolution screens. None of which excites me even a bit.

I used to change my phone every 6-8 months. When the iPhone 3G was released, I was excited to see how nice the interface and potential was with the app store, compared to my Nokia 6630. But it was too limited, too closed and too slow. Then I got the HTC Dream, the first Android phone. Even if it was butt-ugly I loved the openness and features of the phone. But it was also slow. Then, I got a Nexus One phone and not only it was physically beautiful and nice, it was also fast. In the Nexus One, apps open almost instantly and interactions with apps (menus, buttons, screen change) are also damn fast. This was at the start of 2010. Since then, a lot of new smartphones have hit the market but not a single one of them have excited me enough to change my Nexus. So as of date, I’ve keept my Nexus for 18 months, while in the past I would usually have changed two or three times during this period.

The reason is that the new phones doesn’t offer any value for me are mostly:

  • Bigger screens: it is a phone and I really think that the Nexus 3.7’’ is a reasonable limit for a phone screen. 4’’ could make it, but no more.

  • Better screen resolution: which is not much of an improvement on a 3.7’’ screen.

  • More cores, higher CPU cycles, more RAM: my Nexus is pretty fast with current Android versions (thanks Google for not WindowVista-izing the OS), and I don’t feel a need for more RAM memory. Probably people playing 3D games on the phone will appreciate the difference, but I don’t play games on the phone.

  • More megapixels in the camera: more megapixels are not more quality.

  • 4G: which currently doesn’t works here in Europe.

What I would like to see on new phones:

  • Picoprojector: I want to show my friends/coworkers the latest lolcat video or that awesome Call of Duty match I uploaded to youtube on the wall. I want to see films on divx on my hotel room. I want to show that car show photo album without having 8 heads over my phone. These projectors doesn’t need to be very high resolution of produce a huge screen on the wall.

  • More battery time: instead of releasing a phone with 4 cores a graphic accelerator and a huge resolution, release phone with the power and resolution of the Nexus but with 3 or 4 days of autonomy. It’s a pain on the a** having to charge the phone mid-day, and all new phones are the same.

  • Frontal camera: Skype, Google talk, etc support or will support videocalling. Ok, some new Android phones have this, but it on itself not enough for me to change.

  • Digital TV receiver: Phones capable of receiving digital TV have been available for years (I saw one imported from China in 2008). Combined with a picoprojector could let you have a TV anywhere.

Sometimes it looks like phone makers are waiting for Apple to innovate and then make copycat of the new Apple’s features and tagging their phones “iPhone killers”. Sorry, they are not killers, they are copiers at most and now that Apple is mostly there with Android on OS features (notifications, multitasking, etc) Android makers could take a big hit if a new iPhone includes some real hardware innovation.
