A Category III Landing is done with no decision height and no runway visual range. basically its a computer landing the plane!

Just watch

Today I stumble upon this precious gem of creativity by Marcel Krings & Sebastian Muhlhauser, it's called casulo

I've never imagined that it could be possible to store an entire bedroom in just a box

"Casulo is a complete set of room furniture which can be set up in less than ten minutes and later disassembled and repacked like a standard Euro pallet of 80 cm by 120 cm (31.5 inch by 47.2 inch). No tools are needed in the process"

Enough talking, a picture is worth a thousand words …

Today I thought on sharing with you some bash command line tricks to help improve your productivity and help you earn a few geek points

This tricks will help you a lot and helps you to extent your keyboard live by saving a few hundredth strokes

we will dive into the bash history secrets and the ! (bang) command:

• !!
  This bang command, when entered into the bash shell will run the previous command. It basically does the same thing as hitting the up arrow and hitting enter.

• !command
  Ex: !ls
  This will run the last command that started with ‘ls’.

• !command:p
  Ex: !ls:p
  This will display the command instead of running it.

• !$
  Ex: !$ or echo !$
  The last word of the previous command. This the same as hitting Esc + . and is mainly useful for substitutions.

• !$:p
  Instead of running the last word of the previous command this will print it out.

• !*
  Runs the previous command without the first word.

• !*:p
  This will print the previous command without the first word.

• Ctrl + r
  Hit Ctrl + r and start typing, bash will search and show you the last command you rand that satisfies the search text you typed

• Ctrl + s
  Everything you type will not be shown

• Ctrl + q
  Inverts the effect of Ctrl + s, now everything is shown

• Ctrl + a
  Goes to the beginning of the line

• Ctrl + e
  Goes to the end of the line

• Ctrl + w
  Deletes the previous word

• Esc + Esc
  word compellation, it's the same as hitting tab

• Esc + backspace
  Deletes until finding a delimiter, if hitting Esc + backspace on file.txt the .txt will be deleted

What are your favorite command line tricks ?

Last time I posted a video about how to confuse an idiot, this time is a random image I found lying around the web, this one was tricked in to thinking she had won a Toyota

This will prove to be a very simple but handy addition to your toolkit.

As we are working with several paths for the same file (the physical path and its URL) we need to know the root physical path and URL of your web site, (there is an easy and automatic way to do this) that will be the most tricky situation you will find.

Combining JS files into one is fairly easy, just join then !

Combining several CSS files can be tricky as you might have relative paths in them, so we will replace them with full paths.

Be aware that if you use css to preload images this might break it because the image path will change from img/image.jpg to something like  http://www.site.com/path/to/imagef-folder/image.jpg.

Also, the cached file will be served as plain text, with no MIME information so you have to specify an .css extension or your browser wont parse it as being CSS, this could easily be done automatically, but this is just a simple proof of concept.

The code is easy to follow and documented so i will just post typical usage examples  but if have any questions about the code just leave a comment

Usage Example 1 : Javascript

    $c = new fcDiet('path/to/cache/folder');
        $c->webServerPath = 'http://mysite.com/';
        $c->physicalPath = '/var/www/html/mysite/' ;
 
    $c->addFile('file1.js');
    $c->addFile('file2.js');
    $c->addFile('file3.js');
    $c->addFile('file4.js');
 
    echo '<script type="text/javascript" src="'.$c->get() .'"></script>';

Usage Example 2 : CSS

    $c = new fcDiet('path/to/cache/folder');
        $c->webServerPath = 'http://mysite.com/';
        $c->physicalPath = '/var/www/html/mysite/' ;
 
        $c->replacePaths = true;
        $c->appendExtension('css');
 
    $c->addFile('file1.css');
    $c->addFile('file2.css');
    $c->addFile('file3.css');
    $c->addFile('file4.css');
 
        echo '<link rel="stylesheet" type="text/css" href="'. $c->get().'" />';

What could be wrong with this statement ?

Can this be truth ?

Well,  I found a nice benchmark on businessday where they measured the speed of an ancient technology from world war I to deliver 4gb of data against the modern ADSL.

Guess what, that old tech delivered data 95% faster than the TelKom ADSL.

The test was to transfer 4gb of data to a node located at 80km from the starting point. It took 2 hours 6 minutes and 57 seconds for the old tech to transfer data, when the transfer was finished the ADSL upload was only 5% done.

So, the next time you think your connection is slow, try reverting to the old thech, put it on a pen and send it by a pigeon!

Lamentavelmente sempre que precisei do apoio da GNR ou PSP da minha zona nunca o consegui obter em tempo útil pois ou não têm agentes ou não têm viatura disponível!

Uma das vezes, curiosamente durante um jogo de Portugal, tive que me deslocar à esquadra porque o 112 não conseguiu efectuar a ligação uma vez que ninguém atendia, e tentou quatro vezes!

Cheguei eu à esquadra e foi ver os três agentes que lá se encontravam a jogar à batata quente, nenhum deles podia ir socorrer o táxi que vi passar com o SOS ligado!

Fui dispensado com um cordial “Fez bem em ter cá vindo, assim que puder mando alguém ver o que se passa”

Agora mesmo, ia eu feliz da vida a passear o meu filho e quase sou atropelado por um carro com uns miúdos de 15 / 16 anos, mas não liguei muito, nada de mal aconteceu. Cheguei a casa e BUMM os putos acabaram por espatifar o carro numa cerca

“Isto já é demais”, pensei eu, vou à net, tiro o numero da GNR da minha zona e ligo, relato o sucedido e lá vem a resposta “De momento não tenho viaturas disponíveis para ir ai”

Quando questionei o agente sobre a falta de viaturas a resposta foi:

"Não tenho a culpa, queixe-se ao comando"

Entretanto já se passou uma hora, os putos já tiraram o carro da cerca, continuam a fazer peões e a entrar directamente na estrada principal pelo passeio sobem um separador centrar em relva e voltam para trás!

Ora, quem não tem a culpa sou eu, que pago os meus impostos e em troca tenho um serviço ineficiente, digo mesmo incompetente!!

Como sempre parece que a policia é sempre mais prestável quando é para me entalar do que é para me ajudar!

Actually  I was forced in to this club, but that’s another story.

And it’s so much better than one BIG screen.

Believe me, BIG displays are becoming a reality and a BIG problem, display prices are getting lower while their area is increasing.

It’s no longer monetary viable to buy 17’’ or 15’’ monitors as they are almost the same price as a 20’’ one and soon a 30’’ will be about the same price, and so on.

The problem with big monitors is mostly the way you are used to work and how Operating Systems Interfaces are designed.

You usually work with a window at a time, most probably the window is maximized.

With a big monitor this means lots, really lots, of free space and in non fixed layouts buttons far apart, basically you will get lost in all that space and you productivity will decrease.

It’s easy to get lost even if there is no free space, try reading a 300 char line and you will see what I mean!

There are tools to solve this problem by trying to emulate dual monitor setups, but it’s no quite the same.

On the other hand a dual monitor setup are much cleaner, you have space, but not too much, and mostly you can arrange them so you have a central point of attention and an auxiliary area, much like a site where you have the main content and a site bar.

You can concentrate on your work, your window at the main screen while having auxiliary windows, as an email client, IM, whatever on the side monitor.

UI designers must start thinking about this or soon it will be a BIG problem!
