The Diminishing Returns of Long Hours

A lesson I learned during my years in university and had to re-learn once or twice while working in Silicon Valley is that working long hours is beneficial, but only for a very short period of time. One or two 60 hour weeks is enough, as is even a single all-nighter. When you’re sleep deprived, [...]

help! не получается пушить репо на Gitorius

by Ruslan Voloshin | over 2 years ago | Read more

Соклубни,
подскажите, в чем может быть проблема!

Зарегистрировался на Gitorius, создал репо, загрузил паблик rsa-key
ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEA36jK7HjnwnxStR8X6KdCheH+AzjTJERMw7iUaJPUc1STur+EbrN3FBabSqL2NgCncfMbKWFg6Ni74tSf2rH6lU7Ha2zPe5GdYayUEx3y6lVC+WYFpw8A9XXXoIAGNX8Cam2tyGD1IFiXGVAHsRw5MSS/CTcuhXZ8h/EuyIwMQS8= rsa-key-20100112

он у меня сгенерился в таком формате, загрузился нормально - там в гиториусе стоит зеленая галка напротив ключа.

Настроил putty - указал свой логин и указал файл с приватным ключом. Не получается залогиниться по ssh - пишет "server refused our key". Сломал мозг, не понимаю в чем дело. При том fingerprint ключа одинаковый и в pageant и в gitorius, вроде это значит ключ прочитан правильно.

Еще что непонятно и нарпягает - на сайцте gitorius в форме добавления новго ключа есть такая фраза: The key should be in the format of: ssh-algorithm base64-content you@somehost

так вот я так разумею, что в моем ключе ssh-algorith это ssh-rsa, а вот you@somehost я что-то в своем ключе не вижу. Вместо этого есть rsa-key-20100112. И что это за somehost? gitorius.org что-ли?

такой ключ gitorious тоже принимает, но логин все равно не получается :(((

PHP is a templating language

by Yoan Blanc | over 2 years ago | Read more

For my last project, I had to use PHP and managed to make it fun by —among other stuff— rewriting a templating tool. Templates was one of the first thing we did with Batiste for doSimple. It was qregexp based, not very flexible, ugly and for sure, inefficient.

Let’s redo this, keeping in mind that PHP is already a templating language.

<!DOCTYPE html>
<html lang=<?php echo $lang ?>>
<?php echo $html ?>
</html>

This is valid PHP, and can be seen as a template with two parameters: the language ($lang) and some html content ($html).

<?php
$lang = "en";
$html = "<h1>Hello World!</h1>";
// the file above
include("hello.php");

That was too easy. But it’s not very clean, imho because you cannot do anything with the result. Let’s do this a little bit better.

<?php
function template($template, $args) {
 extract($args);
 ob_start();
 include($template);
 $result = ob_get_contents();
 ob_end_clean();
 return $result;
}

echo template("hello.php",
              array("lang" => "en",
                    "html" => "<h1>Hello, World!</h1>"));

This way, you don’t pollute the global scope with variables and are able to reuse templates. It’s still very, very basic but will enable you to understand the final class Template that is used by bluespirit.ch. I’ll show you how it works but let you dive into the PHP code to understand it.

<?php
// templates is a directory
$tpl = new Template("templates");

echo $tpl->index(array("title" => "Hello",
                       "links" => array(1,2,3));

Now the templates, let’s start with the index (the function call above is in fact using __call).

<?php
$this->inherits("layout");
$this->block("head")
?>
<title><?php echo $title ?></title>
<?php
$this->endblock();
$this->block("body")
?>
<h1><?php echo $title ?></h1>
<ul>
<?php
foreach($links as $link):
?>
<li><?php echo $this->link(array("link" => $link)) ?></li>
<?php
endforeach
?>
</ul>
<?php
$this->endblock();

The layout, from which this template inherits.

<!DOCTYPE html>
<html lang=en>
<head>
<meta charset=utf-8>
<?php $this->block("head") ?>
<title>Untitled Document</title>
<?php $this->endblock() ?>
</head>
<body>
<?php
$this->block("body");
$this->endblock()
?>
</body>
</html>

and link, of course.

<?php
echo $link

Which could have been more complex.

That’s the very basics, the final one includes more features like some block control meaning you can no only override a block but also append or prepend some content which is very useful for the usual end of the page scripts. Another one that I like very much is some cache (using APC (or apc_alt) enabling avoiding regenerating a piece of layout everytime.

Having this kind of cache also means that you might ending up doing bad things in the templates (views) like SQL requests. This is for example used on the homepage of bluespirit.ch where the news are coming from a RSS feed parsed by Yahoo! Pipes. It doesn’t cURL it all the time.

All this in on GitHub, get it, fork it, fix it. And I’ve got one question for the PHP masters in the room, how do you do monkeypatching in PHP? (I know how much evil it is, but I promise that I won’t break anything)

Un des premiers outils que nous avions réalisés avec Batiste dans le cadre de nos débuts dosimplesques (pardonnez ce néologisme) a été un système de template. Nous en avons fait quelques-uns même. Tous reposent sur une syntaxe proche d’HTML, donc à base de commentaires remplacés à l’exécution.

C’était sans bien réaliser que PHP est déjà un langage de templating, intrinséquement. Pourquoi serait-il indispensable de mettre ce <?php sinon ? Ceci étant dit, voici un système de templates reposant sur ce fait-là et offrant quelques fonctionnalités sympathiques, telles que : l’héritage, les blocs, l’inclusion d’autres templates, le cache et même l’envoi de headers HTTP pour les plus bidouilleurs d’entre vous.

Le code ainsi que des exemples se trouvent sur GitHub, amusez-vous y.

Sparkline Some Interest With Ruby on Rails

by Ron Evans | over 2 years ago | Read more

Recently, I added some sparkline graphs to a Ruby on Rails application. A sparkline is a very small graphic that displays a large amount of information, typically shown over time, and usually embedded in some other text. Invented by the father of modern infographics Edward Tufte, the sparkline has become a fixture of many online applications that want to visually display some stats in a simple, integrated way.

When it come to adding sparklines into a Ruby on Rails application, there are a couple of different options. You can chart the data on the server, output being an image file. You can also chart the data on the client, with a couple of different JavaScript libraries as available options.

I started my plan, intending to implement my charts on the client-side. The project that appears to have the most flexibility, speed, and options, is an amazing jQuery plugin called jQuery Sparkline. Unfortunately, the project to which I needed to add the sparklines is a bit older, and does not use jQuery. As a result, I was not able to use jQuery Sparkline for this current project.

Another interesting JavaScript sparkline library is lethain's Sparkline.js, but it has not been updated in some time, and is not compatible with current Internet Explorer versions. There is also an interesting looking newer lib topfunky-sparkline-js but I have not tried it out yet.

So that brings us to server-side sparkline generation. If you are using ImageMagick/RMagick then @topfunky once again provides, with the Ruby sparklines gem. This gem provides lots of options for doing all sorts of fancy sparklines.

In my case, I am not using ImageMagick for anything else, so I did not want to install it just for this. What I really wanted was something much lighter-weight, and I was willing to accept a lot fewer options to get it.

It turns out that madrobby has written a library for generating very simple sparklines in pure Ruby code, called spark_pr. The project uses _why's pure Ruby implementation of a PNG generator to do the low-level work.

spark_pr has also spawned an interesting application of it from @technoweenie called Sparkplug, which is a Rack module that generates spaklines from CSV data on the fly, using Rack handlers and Rack caching.

Once I had seen Sparkplug's minimal elegance, it seemed spark_pr was the option for me. I decided to incorporate spark_pr into my application. Given that the app was written with a dedicated approach to keeping a clean RESTful interface, and that the database already contained the time-series data, it was quite easy to incorporate. Here is what I had to do:

Step 1: Put spark_pr.rb file into lib directory. I just grabbed the code from the repo, and dropped it into my project. You may decide to have a more sophisticated way to do it, such as using git submodules.

Step 2:

require "spark_pr"

in your controller

Step 3:

include Spark

in your controller

Step 4: Add PNG format to controller action that was already returning my time-series data, and return the sparkline PNG data:

Note that this controller action is already returning XML or JSON. PNG is just another format to be added, if you have a well-designed RESTful controller action.

Step 5: Put image_tag that requests the sparkline PNG image file into the view where you want it to appear, like this one:


Voila! Refresh that view and you should now be looking at your ultra-hipster-chic sparkline graph. It is surprising how much more information comprehension a person has, when they are seeing a visual representation of their data. Plus it looks cool.

3> smerl:new(foo).

4> Mod = smerl:new(foo).

5> {ok, Mod2} = smerl:add_func(Mod, {function,1,bar,0,Forms}, true).

              [{function,1,bar,0,[{clause,1,[],[],[{atom,1,ok}]}]}],
              false}}
