Fork me on GitHub
LESS extends CSS with: variables, mixins, operations and nested rules. Best of all, LESS uses existing CSS syntax. This means you can rename your current .css files to .less and they'll just work.

Variables

Variables allow you to specify widely used values in a single place, and then re-use them throughout the style sheet, making global changes as easy as changing one line of code.

@brand_color: #4D926F;

#header {
  color: @brand_color;
}

h2 {
  color: @brand_color;
}

Mixins

Mixins allow you to embed all the properties of a class into another class by simply including the class name as one of its properties. It's just like variables, but for whole classes. Mixins can also behave like functions, and take arguments, as seen in the example bellow.

.rounded_corners (@radius: 5px) {
  -moz-border-radius: @radius;
  -webkit-border-radius: @radius;
  border-radius: @radius;
}

#header {
  .rounded_corners;
}

#footer {
  .rounded_corners(10px);
}

Nested Rules

Rather than constructing long selector names to specify inheritance, in Less you can simply nest selectors inside other selectors. This makes inheritance clear and style sheets shorter.

#header {
  color: red;
  a {
    font-weight: bold;
    text-decoration: none;
  }
}

Operations

Are some elements in your style sheet proportional to other elements? Operations let you add, subtract, divide and multiply property values and colors, giving you the power to do create complex relationships between properties.

@the-border: 1px;
@base-color: #111;

#header {
  color: @base-color * 3;
  border-left: @the-border;
  border-right: @the-border * 2;
}

#footer { 
  color: (@base-color + #111) * 1.5;
}

Head over to the Docs for information on installing and using LESS.

CUIベースなのに無駄にビジュアルなPython用デバッガ - pudb

by ats — posted at 2010-02-09 11:05 last modified 2010-02-09 11:05

pudbは，CUI環境(つまりシェル)で動くGUIライクなデバッガ。Pythonには標準でpdbというデバッガがついてくるけど，コマンドラインベースでちょっと使い方が面倒だよね。pudbはpdbよりノリがいい。まあスクリーンショットを見てもらうのが早いかな。

CUIベースでGUIっぽいことをするというのは，レトロなノリだよなあ。でもCUIベースならシェルが動く環境ならどこでも動く，という利点もある。ローカルのPythonでもssh越しのPythonでも，シェル上なら同じように動くというのは嬉しい。

インストールは簡単。いつものごとくeasy_installを使って「$ easy_install pudb」でOK。デバッガを実行中，使い方が分からないときは「?」を押すとインストラクションが出てくる。

とりあえず覚えるべきコマンドは4つくらいかな。

  • s : ステップ実行(ステップイン)
  • n : ステップ実行(ステップオーバー)
  • c : 実行の継続
  • b : ブレークポイントを置く，消す

さて，デバッガが有効なのは開発の場面ばかりではない。入門者がデバッガを使うと，プログラミングの学習につながる。デバッガでコードを見つつ，変数などを確認しながら，プログラムの挙動を学べる，という利点がある。SDの木村明治さんの記事にも同じようなことが書いてあったな。逆に，Pythonの達人になるとデバッガを使わないらしいけど。僕もあまり使わないかな。

さて，試しにpudbを使ってPythonの簡単なプログラムの挙動を見てみよう。Pythonの機能の中でも比較的分かりづらい「デコレータ」がどのような動きをするのか，pudbを使ってソースコードを追いながら確認してみる。

まず，以下のソースをファイルに保存する(ファイル名はdectest.pyとしておく)。ちなみにこのコードは，inspectモジュールを使って関数の引数情報を取り出し，表示する，という簡単なプログラム。 

#!/usr/bin/env python




import inspect
from pudb import set_trace; set_trace()




def sessionmethod(func):




    f = func
    def wrapper(*params, **kwargs):
        arg = inspect.getargspec(func)
        print arg
        #if 's' in params[0] and 
        return func(*params, **kwargs)
    return wrapper




if __name__ == '__main__':




    @sessionmethod
    def foo(hoge, s=None):
        print "FOO!"
    foo(1, s=2)

上の方に「from pudb import set_trace; set_trace()」という行が見える。これがpudbを呼び出すおまじない。

次に，このコードを実行する。「$ python2.5 -m pudb.run dectest.py」というコマンドを入力すると，pudb上でコードを実行できる。早速pudbを使ってプログラムの実行状況を見ながら，コードを実行してみよう。

sessionmethod()関数の直下や，内包関数wrapper()の直下に「b」キーを使ってブレークポイントを設置してコードを実行してみよう。ステップイン，ステップオーバーを使い分けながら実行すると，デコレータがどのようなタイミングで呼ばれているのか目で確認できるはずだ。

このデコレータは関数の定義時に呼ばれる部分と，関数の呼び出し時に呼ばれる部分に分かれているんだけど，どのような仕組みになっているのか，よく分かると思う。

挙動が把握しにくいコードは，デバッガを使って動きを追って見ると，仕組みが理解しやすいのです。

Superb resources. Thanks for sharing

Inside the Webb January 25th, 2010

This is a great collection of jQuery plugins, I may even try some on my blog! I’m always impressed with how much jQuery has grown and allowed so much interactivity with pages.

emptywalls January 25th, 2010

I use jQuery Validate and jQuery Form with great success. They are made to interact with each other, so validation and then AJAX submit are a snap.

YUI Library Examples: Slider Control: Horizontal Slider with Tick Marks

Slider Control: Horizontal Slider with Tick Marks

This example uses the YUI Slider Control to implement a basic horizontal slider with tick marks & that is, with predefined intervals at which the slider thumb will stop as it's dragged. (By default, a slider thumb can be dragged one pixel at a time.)

Here are some important characteristics of this implementation:

  • The slider range is 200 pixels.
  • The slider movement is restricted to 20 pixel increments.
  • Custom logic is applied to convert the current pixel value (from 0 to 200) to a "real" value. In this case the "real" range is 0 to 300.
  • Once the slider has focus, the left and right keys will move the thumb 20 pixels (changing the "real" value by 30).
  • When the slider value changes, the UI is updated. The title attribute of the slider background is updated with the current value, and the text field is updated with the current "real" value. These techniques can help inform assistive technologies (like screen reader software) about the slider's current state.

Building a Horizontal Slider

You supply your own markup for the slider. Keep in mind the following points about markup for YUI Slider Control implementations:

  • The thumb element should be a child of the slider background
  • The tabindex attribute lets this element receive focus in most browsers.
  • We use the Sam skin for a 200px horizontal slider and use the thumb-n.gif thumb image from the build assets
  • The background element is assigned a new image from the build assets.
  • If the slider background can receive focus, the arrow keys can be used to change this slider's value.
  • We use an <img> element rather than a CSS background for the thumb to get around a performance bottleneck when animating the thumb's position in IE.
  • Don't apply a CSS border to the slider background

http://en.wikipedia.org/wiki/Sweave

Sweave

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Sweave is a function in the statistical programming language R that enables integration of R code into LaTeX or LyX documents. The purpose is "to create dynamic reports, which can be updated automatically if data or analysis change".[1]

The data analysis is performed at the moment of writing the report, or more exactly, at the moment of compiling the Sweave code with Sweave (i.e., essentially with R) and subsequently with LaTeX. This can facilitate the creation of up-to-date reports for the author.

Because the Sweave files together with any external R files that might be sourced from them and the data files contain all the information necessary to trace back all steps of the data analyses, Sweave also has the potential to make research more transparent and reproducible to others. However, this is only the case to the extent that the author makes the data and the R and Sweave code available. If the author only publishes the resulting PDF document or printed versions thereof, a report created using Sweave is no more transparent or reproducible than the same report created with other statistical and text preparation software.

Bort – A Base Rails Application

What is Bort?

Bort is a base rails application that takes the pain out of setting up new projects. A lot of people do the same things, with every project. Not very DRY is it? So we decided to build a base application that your can use to start your projects.

Where do I get Bort?

Your can get Bort from Github:

http://github.com/fudgestudios/bort/tree

Once you’ve downloaded the file, unzip it, change the settings in database.yml, run rake db:migrate and you’re ready to rock.

Features

So you’re probably wondering what you get from Bort? Well here goes…

RESTful Authentication

RESTful Authentication is already setup. The routes are setup, along with the mailers and observers. Forgotten password comes setup, so you donít have to mess around setting it up with every project.

The AASM plugin comes pre-installed. RESTful Authentication is also setup to use user activation.

User Roles

Bort now comes with Role Requirement by Tim Harper. A default admin role is predefined along with a default admin user. See the migrations for the admin login details.

OpenID Integration

OpenID integration is now integrated with RESTful Authentication. Shazzam!

Will Paginate

We use will_paginate in pretty much every project we use, so Bort comes with it pre-installed.

Rspec & Rspec-rails

You should be testing your code, so Bort comes with Rspec and Rspec-rails already installed so youíre ready to roll.

Exception Notifier

You donít want your applications to crash and burn so Exception Notifier is already installed to let you know when everything goes to shit.

Asset Packager

Packages up your css/javascript so youíre not sending 143 files down to the user at the same time. Reduces load times and saves you bandwidth.

Routes

The routes for RESful Auth and the forgot password stuff are already sorted for you.

Settings YAML

There is a settings.yml file that contains site-wide stuff. The site name, url and admin email are all used in the RESTful Auth mailers, so you donít need to worry about editing them.

Database YAML

The database.yml defaults to sqlite3 but also contains the settings for MySQL in comments so you can switch over easily.

Capistrano Recipe

Bort comes ready to rock capistrano. The recipe that is setup is based on using git and passenger. Edit as you see fit.

Uses the Database for Sessions

Bort is setup to use the database to store sessions by default.

Misc
  • password and password_confirmation are set up to be filtered
  • there is a default application layout file
  • a page title helper has been added
  • index.html is already deleted
  • rails.png is already deleted
  • a few changes have been made to the default views
  • a default css file with blank selectors for common rails elements

Bort Suggestions?

If you have any suggestions for improvements, or bug fixes then please fork the project and let us know, or you could send us suggestions using User Voice.

POW!

As much as we try to convince ourselves otherwise, the WORK POOP is inevitable. For those who hate pooping at work, following is the Survival Guide for taking a dump at work. Memorize these definitions and pooping at work will become a pure pleasure.

ESCAPEE
Definition: a fart that slips out while taking a leak at the urinal or forcing a poop in a stall. This is usually accompanied by a sudden wave of panic embarrassment. This is similar to the hot flash you receive when passing an unseen police car and speeding. If you release an escapee, do not acknowledge it. Pretend it did not happen. If you are standing next to the farter in the urinal, pretend you did not hear it. No one likes an escapee, it is uncomfortable for all involved. Making a joke or laughing makes both parties feel uneasy.

JAILBREAK (Used in conjunction with ESCAPEE)
Definition: When forcing poop, several farts slip out at a machine gun pace. This is usually a side effect of diarrhea or a hangover. If this should happen, do not panic. Remain in the stall until everyone has left the bathroom so to spare everyone the awkwardness of what just occurred.

COURTESY FLUSH
Definition: The act of flushing the toilet the instant the nose cone of the poop log hits the water and the poop is whisked away to an undisclosed location. This reduces the amount of air time the poop has to stink up the bathroom. This can help you avoid being caught doing the WALK OF SHAME.

WALK OF SHAME
Definition: Walking from the stall, to the sink, to the door after you have just stunk up the bathroom. This can be a very uncomfortable moment if someone walks in and busts you. As with all farts, it is best to pretend that the smell does not exist. Can be avoided with the use of the COURTESY FLUSH.

OUT OF THE CLOSET POOPER
Definition: A colleague who poops at work and damn proud of it. You will often see an Out Of The Closet Pooper enter the bathroom with a newspaper or magazine under their arm. Always look around the office for the Out Of The Closet Pooper before entering the bathroom.

THE POOPING FRIENDS NETWORK (PFN)
Definition: A group of coworkers who band together to ensure emergency pooping goes off without incident. This group can help you to monitor the whereabouts of Out Of The Closet Poopers, and identify SAFE HAVENS.

SAFE HAVENS
Definition: A seldom used bathroom somewhere in the building where you can least expect visitors. Try floors that are predominantly of the opposite sex. This will reduce the odds of a pooper of your sex entering the bathroom.

TURD BURGLAR
Definition: A pooper who does not realize that you are in the stall and tries to force the door open. This is one of the most shocking and vulnerable moments that can occur when taking a dump at work. If this occurs, remain in the stall until the Turd Burglar leaves. This way you will avoid all uncomfortable eye contact.

CAMO-COUGH
Definition: A phony cough that alerts all new entrants into the bathroom that you are in a stall. This can be used to cover-up a WATERMELON, or to alert potential Turd Burglars. Very effective when used in conjunction with an ASTAIRE.

ASTAIRE
Definition: A subtle toe-tap that is used to alert potential Turd Burglars that you are occupying a stall. This will remove all doubt that the stall is occupied. If you hear an Astaire, leave the bathroom immediately so the pooper can poop in peace.

WATERMELON
Definition: A turd that creates a loud splash when hitting the toilet water. This is also an embarrassing incident. If you feel a Watermelon coming on, create a diversion. See CAMO-COUGH.

HAVANA OMELET
Definition: A load of diarrhea that creates a series of loud splashes in the toilet water. Often accompanied by an Escapee. Try using a Camo-Cough with an Astaire.

UNCLE TED
Definition: A bathroom user who seems to linger around forever. Could spend extended lengths of time in front of the mirror or sitting on the pot. An Uncle Ted makes it difficult to relax while on the crapper, as you should always wait to drop your load when the bathroom is empty. This benefits you as well as the other bathroom attendees.

FLY BY
Definition: The act of scouting out a bathroom before pooping. Walk in and check for other poopers. If there are others in the bathroom, leave and come back again. Be careful not to become a FREQUENT FLYER. People may become suspicious if they catch you constantly going into the bathroom.

Debugging with FirePHP

By Heath Nail (HeathNail)
This is a quick hack to have the debugger use FirePHP for debugging.

You may have read the other article on FirePHP which deals with the query log, if not check it out here:
http://bakery.cakephp.org/articles/view/baking-cakes-with-firephp

With a little massaging of Cake's Debugger class you can have all errors logged to the Firebug console instead of having them displayed on your site.

Things you'll need for this to work:

You'll need to download the FirePHP.class.php file and save it to vendors. I saved it to vendors/FirePHP/FirePHP.class.php

Then save the following file to vendors/FirePHP/FirePHP.debugger.php:
Download code <?php
/**

Now add the following line to app/config/bootstrap.php:
Download code <?php
App::import('Vendor', 'FirePHPDebugger', array('file' => 'FirePHP' . DS . 'FirePHP.debugger.php'));
?>

When an error occurs (and debug > 0) you'll see something like this in your FireBug console:
Download code http://yoursite.com
["Notice (1024): Foo [APP\config\bootstrap.php, line 46", Array(3)]

Hover over the "Array(3)" and you'll see a new window open with the Trace, Code, and Context info.

I haven't tested this code thoroughly, so if you have an issue leave a comment here and we can work it out.

Happy Baking!
Heath

1 Great, but

do you think it's possible to move the "SQL output" as well?

But still: thank you for this sweet integration.

Very nice, Nail!

I have used this in my AppController to show the results that sended to views, it's includes all actions, see:


    function beforeRender() {
        if (Configure::read() > 0 && version_compare(PHP_VERSION, '5.2')) {
            fb($this->viewVars);
        }
    }

Web Development with Firefox

Rapid Web Development and Testing with Mozilla Firefox

Web Development with Mozilla Firefox

Successful web development requires certain essential tools. One of the best tools available for web development and testing is the Mozilla Firefox web browser. Mozilla Firefox Screen Shot

"Out of the box" Firefox has an extensive list of built in development tools. Secondly, the extensible design of Firefox has encouraged the development of many very useful extensions to help in the design and troubleshooting of web pages. The additional functionality can be a real time saver during the Web development process.

Quick Tip

Another important feature of Firefox is it's standards-compliant rendering engine. Firefox's page rendering has proven to be very close to the official W3C behavior and display recommendations. Consequently, web pages that render correctly in Firefox usually work reasonably, if not perfectly, in most other browsers with only minor adjustments.

Built-In Firefox Web Development Tools

Firefox comes with several standard tools that are built into the browser. By themselves, these tools are powerful enough to consider Firefox an essential web development tool.

These tools include:

  • An expanded page source viewer.
  • The ability to display detailed information about a web page.
  • A JavaScript debugging tool.
  • A real-time DOM inspector and editor.

Viewing the Source of a Page

Like most browsers, Firefox provides the ability to view the source of a page. Firefox offers a different twist, though. Instead of sending the source code to an external text editor, Firefox uses its own source viewer with syntax highlighting and color coding of the html tags.View Page Source in Firefox

When content on a web page is highlighted, Firefox also offers the option to view the selected source by opening a version of the source code view, with the selection's markup highlighted in the source. This makes it easier to find a specific section of a web page in the overall source code.

Quick Tip

You can view the source of a page by choosing "View > Page Source" through the menu system or by choosing View Page Source form the context menu (keyboard shortcut Ctrl-U).

You can view only part of the source of a page by highlighting a portion of the web page and then right-clicking to bring up the context menu and choosing "View Selection Source".

Page Info Reports

Firefox provides detailed information about a page through the Page Info window.Firefox Page Form Reports

  • The General tab displays information about the page such as url, size, and rendering mode.
  • The Form tab displays the forms on the page and details about the fields in the forms.
  • The Links tab lists the links in the page, including hyperlinks and style sheets.
  • The Media tab contains information about all media on the page, such as images and favicons.

Quick Tip

You can access the Page Info window from "Tools > Page Info" or by right-clicking on the page and selecting "View Page Info" from the context menu.

Javascript Console

The Javascript Console is a tool for JavaScript developers to write and test javascript code snippets or external JS files. The console provides an interface to use XPCOM components, a means for dynamic script loading, and the reporting of Javascript related and CSS errors in the web page.
Firefox Javascript Console

DOM Inspector

The DOM Inspector provides direct access to the Document Object Model. For each element, the inspector provides a list of information including which CSS rules are affecting any given element in order of their cascade priority. For quick access to the DOM for a selected element, you can also install the Inspect Element extension.
Firefox DOM Inspector

Quick Tip

Firefox comes with the DOM inspector, but on Windows machines, you need to choose it when you first install the browser. To do this choose "Custom Install" and then select "Web Developer Tools". Once installed, the Firefox DOM Inspector is under the Tools menu.

Firefox Web Development Extensions

In addition to the built in developer tools, Firefox provides the ability to add additional web development functionality through the use of add-on programs called extensions. Some of the most useful extensions are described in the following slides. Many more developer extensions are available on the Mozilla update site. Look under the developer tools submenu to find additional web developer extensions.

The Web Developer Extension

This extension, by itself, makes Firefox an indispensable tool for Web development and testing. The Web Developer Extension adds a toolbar to the browser containing various web developer tools. It outlines page elements, displays the size of images, gives CSS and form information, disables certain elements on a page, and much more.
Firefox Web Developer Extension

Accessibility

Accessibility Extensions for Firefox helps in the testing of a page's structural markup to meet the needs of people with disabilities. Fangs gives a textual representation of a page, similar to the way it is read by a screen reader. For more accessibility testing try the Accessibar Firefox extension or the Web Developer Extension.
Accessibility Extensions for Firefox

Colors

Colorzilla is an eyedropper tool. Hovering over an element shows color info, DOM path info, and the X,Y offset from the previous click.
Firefox Colorzilla Extension

Cookies

The Add & Edit Cookies extension allows for the adding and editing on cookies to a page. This extension is a more featured version of the View Cookies extension.
Add and Edit Cookies

CSS

The CSSViewer inspects elements on a page to give a complete rundown of the CSS declaration for a chosen element.
Firefox CSS Viewer
Aardvark is a CSS debugger with keyboard modifiers. It displays items on the page such as the element name and id or class name of a selected element.

Quick Tip

For the Aardvark extension, as you glide the mouse over the page, you will see a red rectangle framing each element under the cursor. You will also see a little yellow caption showing the HTML element type and its class or id if they exist.

Debugging

Firebug helps in debugging AJAX, DHTML, and JavaScript web applications. It will display errors that occur during the rendering of a page, will place the pointer on the appropriate line, and allows for the inspection of different values of the DOM.
Firefox Firebug Extension

Links

LinkChecker checks every link on a web page to find bad links. The simple color coding scheme makes it easy to quickly spot a bad link on a page.
Firefox Link Checker Extension

Measurements

MeasureIt draws a ruler across a web page to display the width, height, or alignment of any page element.
Firefox Measure It Extension

Page Information

The Extended Statusbar extension adds information to the status bar displaying the average download speed, bytes downloaded, load time, number of loaded images and percentage of the page loaded. It is similar to Opera's status bar.
Firefox Extended Statusbar Extension
The MetaTags Sidebar extension displays information from the source code, such as the code lying between the tags like description, keywords, and links.
Meta Tags

Page Parameters

Live HTTP Headers displays information about the HTTP headers on a page in real time.

UrlParams is a sidebar extension that displays the form parameters Firefox has sent to the server on the last request. It will also let you change or add parameters and re-submit the request.
URLParams

User Agents

User Agent Switcher allows Firefox to identify itself as a different web browser, such as IE or Opera, to a web server.
Firefox User Agent Switcher Extension

Validation

HTML Validator adds HTML validation inside Firefox's source viewer.
Firefox HTML Validator Extension

View Pages in Other Browsers

IE Tab is an extension that launchers your URL in Internet Explorer inside of a Firefox tab. A simple time saver when checking pages for cross-browser compatibility.

IE View allows the current page or a selected link to be opened in the Internet Explorer browser. OperaView provides the same functionality for the Opera web browser. In addition, FirefoxView allows you to open Firefox to the current page or selected link from within Internet Explorer.
IE Tab

Firefox Bookmarklets

Bookmarklets (favlets) are small JavaScript programs that are stored as a URL within a browser's bookmark and add additional functionality to the browser. While most of what bookmarklets can due are already bundled into extensions, two good sources of bookmarklets can be found at Slayer Office and Square Free. The Slayer Office Favlet Suite is particularly useful to show things such as a list of colors on a page or to change hidden fields on a form.
Slayer Office Favlet Suite

Firefox Developer Tools Extensions

In addition to extensions which help a developer to code and test a page there a several Firefox extensions that are designed to complement/replace various desktop development tools. These extensions provide an interesting alternative to software such as Filezilla or Nvu.

Editors

Codetch is a code editor for various markup languages. It emulates many of the features seen in Dreamweaver into a editor inside of Firefox.
Firefox CodeTch Extension

FTP

Fireftp is a FTP client which allows for easy access to a FTP server.
Firefox FireFTP Extensions

Images

MozImage is a simple image viewer and browser.
Firefox FireFTP Extensions

Screenshots

The Pearl Crescent Page Saver saves an image of a web page to a file in PNG format. The Page Saver extension uses the new canvas feature that was introduced in Firefox 1.5.

The Screen Grab extension takes a screenshot of a web page in several different ways. Most importantly, it allows you to capture the entire web document that you are viewing.
Firefox Screen Grab Extension

The End

While it may seem daunting at first take the time to get to know many of the extensions mentioned in the previous slides. It will save a lot of frustration and time. Especially become familiar with the Web Developer extension, the CSSViewer extension, and the Firebug Extension. You will be glad you did!
