The state of package management on Mac OS X

List of software package management systems
OS X
  • fink, for OS X, derives partially from dpkg/apt and partially from ports.
  • MacPorts, formerly called DarwinPorts, originated from the OpenDarwin project.
  • Homebrew, with close Git integration.
  • Mac App Store: Official digital distribution platform for OS X apps. Part of OS X 10.7 and available as an update for OS X 10.6.
  • Homebrew: Package manager for OS X, based on Git
  • Fink: A port of dpkg, it is one of the earliest package managers for OS X.
  • MacPorts: Formerly known as DarwinPorts, based on FreeBSD Ports (as is OS X itself)
  • Joyent: Provides a repository of 10,000+ binary packages for OS X based on pkgsrc[1]
  • Nix package manager: Provides atomic upgrades and rollbacks, side-by-side installation of multiple versions of a package, multi-user package management and easy setup of build environments
  • Zero Install (0install): Cross-platform packaging and distributions software. Uses GnuPG and GTK+ on OS X.

30 Code Playgrounds and Sharing Tools

Most people know about jsFiddle because it is an amazing tool that allows you to quickly test and share small pieces of code. No wonder my jsFiddle examples post is getting a ton of traffic. But, there are many other awesome web based sandbox testing tools that you might find useful. Did you know that there are SQL and NodeJS sandboxing tools out there? It is so convenient to quickly mess around with code online and collaborate with other programmers. Below you will find some of the best free code playgrounds and sandboxing tools for testing, debugging and sharing your code snippets (I put my favorites in bold).

1. JSFiddle – supports JS, CSS, HTML and dominates in this space with a simple approach and great features like sharing, embedding, etc.

2. JSBin – looks very similar to JSFiddle and allows HTML, JS, and CSS.

3. Tinkerbin – another code playground for HTML, JS, and CSS.

4. CodePen – online HTML, CSS, and JS editor with sharing tools and collections of snippets organized for code inspiration.

5. CodePad – allows you to test C, C++, Perl, Python, Ruby, and more online.

6. D3 PlayGround – a tool for exploring and developing visualizations using D3.

7. HTML5 Snippet – testing ground for HTML5, CSS3 and JS.
8. PasteBin – simple and clutter-free HTML/JS open source sandbox tool. I like that it’s open sourced on GitHub.

9. CSS Desk – Test your HTML and CSS code online.

10. Dabblet – Interactive CSS playground and code sharing tool.

11. JSapp – a playground for testing your NodeJS code online.

12. TryItEditor – lets you test your HTML code markup.

13. PHP Fiddle – Let’s you test out PHP Code online.

14. PYCH – The online Python Code Checker

15. PY I/O – Online Python IDE built with Google App Engine

16. JavaScript Sandbox – Online tool to test JavaScript code

17. RegexPal – JavaScript Regular Expression Tester

18. Codecademy Labs – a place for you to program in Ruby, Python, and JavaScript online

19. SQLFiddle – allows you to create a DataBase and test SQL code.

20. IDEone – an online compiler and debugging tool which allows you to run code online in more than 40 programming languages

21. Mozilla Thimble – lets you write and edit HTML and CSS right in your browser and instantly preview your work.

22. Liveweave – a HTML5, CSS3 & JavaScript playground for web developers and designers.

23. Practicode – another online tool for editing your code snippets with support for HTML, CSS and VBScript.

24. PHP Sandbox – lets you test php functions online with many different version of PHP.

25. Snippet.IO – free tool that lets you share code snippets easily.

26. HTML5 PlayGround – lets you click on pre-defined HTML5 tags and see how the code works instantly in preview.

27. Tmpltr – another JSFiddle clone but focused on realtime template binding.

28. Google Code PlayGround – allows you to instantly test code using various Google APIs.

29. PasteHTML – a sandbox for playing with HTML, CSS and JS with an API and a bookmarklet to create a snapshot of any web page and store it online.

30. Tinker – a quick and easy tool for writing and sharing code

Have I missed any online tools to test and share code snippets?
Update:

Today, I was introduced to Runnable and it is pretty impressive. It let’s you runa and share code in the browser and it supports php, python, nodejs and a variety of APIs. Also, Plunker is an interesting tool for creating and sharing web development work that uses the ACE editor, lets you split code into multiple files, live preview, etc…
Also, here is a WebGL Playground

Noxell 一個簡單的 
Introducing Zoxel
I needed to edit small voxel models for a voxel based project I've been hacking on.  After hunting around for a while, I couldn't find a simple, open-source, Linux friendly application.  So I've started development on my own, Zoxel.

Zoxel is written in pure Python, with minimal dependancies.  It's being developed on Linux Mint, an Ubuntu variant.
Version 0.1.0 is available.  It's pretty minimal, think MS Paint for voxels.
Source is available from Github here.
Instructions how to run Zoxel are here.

Sproxel: What Is Sproxel?
What Is Sproxel?
Sproxel (short for "Sprite Voxel Editor") is a 3d interface designed to let the user quickly create and edit voxel-based 3d models. The creation process and resulting geometry can be thought of as an extension to 2d pixel art. 
Sproxel is an open source project hosted on google code here: Project Page.  It is being developed on both

 Windows and Linux using the QT windowing framework,

 which should keep it snappy and extensible well into the future.  Sproxel is still in its infancy, but can already generate sprites for custom display and/or game engines.

Super Dodge Ball was always one of my favorite NES games... I guess it was something about the concept of a sport where you smashed somebody with a ball so hard that it caused them to die which appealed to me. Of course, if you did this in any professional sport, you would get ejected from the game and have to suffer by going home to sit in your huge mansion. Poor you. But in Super Dodge Ball, killing your teammate was not only encouraged... it was the object of the

Honoo no Doukyuuji - Dodge Danpei (Japan) ROM Download for Sega Game Gear - CoolROM.com

http://www.zophar.net/utilities/snesgraph.html
  • BgMapper A fabulous tool for mapping enthusiasts, BGMapper allows for viewing tiles and background images saved in .ZST-format Save States, including large Mode7-style maps. It includes facilities for exporting, as well.
  • Killer Instinct Image Explorer This utility lets you decode images in the Killer Instinct ROM. You can dump sprite data and intro movie frames, and possibly much more.
  • MrClick's HiColEd Similar to Killer Instinct Image Explorer, this views 16bpb bitmap graphics from the Killer Instinct hard drive image.
  • Pic2SNES This program converts standard graphics formats into SNES tile format. I haven't tried it.
  • SMC-Ripper This is a good sprite editor with a nice GUI. It supports 1, 2, 3, 4 and 8 bitplanes SNES tiles and NES tiles. It also has some palette tools.
  • SNES Palette Editor A program which allows you to change the colors that are used in a rom.
  • Sprite Edit A sprite editor for SNES ROMs. The palette is horrible, and so is the GUI. But, it does work. Take a look for yourself. You can change bitplanes, and colors. First one I've seen for Win9x.
  • SpriteView This little program lets you view sprites saved in Save States of SNES games from ZSNES. It also lets you view sprites from roms of the N64, NES, Genesis, TG16, Virtual Boy, and even Windows Icons. Although it doesnt let you edit them, it still is nice, and who knows, it might be big one day.
  • Tiler This program is sorta like TileView, although with Tiler, it supports more layers, has a nice mouse driven GUI, and runs at a better resolution. Check them both out.
  • TileView This little program lets you view tiles saved in Save States of SNES games. Although it doesnt let you edit them, you can still view mode 7 graphics, which other programs do not have that option.

  • ROM Hacking Resources
  • General ResourcesEdit
  • ROMHacking.net - This is like a hub where the various hacking communities meet.  It hosts a large variety of major ROM hacks and translations.  Also hosts numerous FAQs and tools to help aspiring hackers get started.
  • Data Crystal - A wiki hosted by ROMHacking.net.  While it is a bit outdated at this point, it is still a good resource for information about different editors and links to a handful of prominent hacks.
  • FuSoYa's Niche - Site of the creator of the popular Super Mario World editor, Lunar Magic.  Also hosts a set of tools for ROM expansion, patching, compression, etc.
  • Zophar's Domain - A site that hosts lots of smaller patches, such as spoofs, as well as a significant amount of major ones.  Hosts a lot of content that can't be found on ROMHacking.net

  • ProgramsEdit
  • General purpose 2D graphics/tile editorEdit
  • Tile Molester. Works with Java, practically can edit any game.


  • Hex EditorEdit
  • XVI32 or Translhextion. You can edit the bytes of the ROMs, i.e. everything. Some values are obvious and some text is already ASCII.

  • Game SpecificEdit
  • Super Mario WorldEdit

  • Super Mario World Central - The largest site dedicated to SMW hacking.  Hosts hundreds of hacks and is a resource for SMW hacking utilities and knowledge.  Also has a very active community and forums.
  • X-Mario - Prominent Japanese site that hosts a variety of hacks.  Worth noting is that Japanese hacks are usually more reliant on creating challenging gameplay and are less flashy or graphically modified than their Western cousins.
  • Raocow's Talkhaus - The community for the most prominent let's player in SMW hacking.  Whether or not you enjoy his commentary, this site remains a great resource for discovering hacks, as the community here is generally focused on hacks that the SMW Central community doesn't cover.
  • VIP Wiki - Japanese wiki dedicated to the development of 2channel's series of popular hacks, the VIP & Wall Mix series.  Hosts the 5 current installments and news about the sixth, currently a work in progress.
  • Super MetroidEdit

  • Metroid Construction - The most prominent and active Super Metroid hacking community currently.  Hosts a large variety of hacks, resources, FAQs, and an active community and forum.  Originated in m2k2 before becoming its own dedicated site.
  • Metroid Construction Wiki - As its name implies, a wiki created by the Metroid Construction community.
  • Metroid 2002 - The former most prominent and active Super Metroid hacking community previously.  While it has since been foregone in favor of Metroid Construction, it can still be a valuable resource for knowledge about the more advanced mechanics and inner workings of Super Metroid (as well as other games in the series).
  • The Legend of Zelda: A Link to the PastEdit
  • Zelda Construction - Despite its huge popularity, the hacking community for ALttP is relatively small.  This is mainly due to the lack of a truly good editor, though one is in the works.  This community is a spin-off of Metroid Construction devoted to hacking of ALttP and other games in the series.
  • EarthBoundEdit
  • Starmen.net - Home of the hacking utility PK Hack, an editor for modifying the EarthBound/Mother 2 ROM.  Has an active hacking community in the PK Hack section of its forums, where links to completed hacks can also be found.
  • Yoshi's IslandEdit
  • Super Mario World Central - In addition to Super Mario World, smwcentral is a budding hub for Yoshi's Island hacking.  While it only hosts a few complete hacks, the community is very active, and new content is being produced at a consistent pace.
  • YI Hacking Wiki - A knowledge base for Yoshi's Island hacking.
  • Final Fantasy III (VI)Edit
  • FF6 Hacking - Home to a large community of Final Fantasy VI hackers, complete with active forums, links to patches, and FAQs and guides for those looking to get into hacking the game.
  • Final Fantasy TacticsEdit
  • Final Fantasy Hacktics - Community for FFT hacking with a variety of completed hacks, patches, and resources.

  • Compiler Design Tutorial
 PDF Version  Quick Guide  Resources  Job Search  Discussion
A compiler translates the code written in one language to some other language without changing the meaning of the program. It is also expected that a compiler should make the target code efficient and optimized in terms of time and space.

Compiler design principles provide an in-depth view of translation and optimization process. Compiler design covers basic translation mechanism and error detection & recovery. It includes lexical, syntax, lexical syntax  and semantic analysis as front end, and code generation and optimization as back-end. exposure to Assembly Programming x86 process code generation and optimization as back-end.
In Fix Post fix Postfix Reverse Polish notation


Audience

This tutorial is designed for students interested in learning the basic principles of compilers.Enthusiastic readers who would like to know more about compilers and those who wish to design a compiler themselves may start from here.

Prerequisites
This tutorial requires no prior knowledge of compiler design but requires basic understanding of at least one programming language such as C, Java etc.It would be an additional advantage if you have had prior exposure to Assembly Programming.

...

  • Syntax analysis or parsing is the second phase of a compiler. In this chapter, we shall learn the basic concepts used in the construction of a parser.
We have seen that a lexical analyzer can identify tokens with the help of regular expressions and pattern rules. But a lexical analyzer cannot check the syntax of a given sentence due to the limitations of the regular expressions. Regular expressions cannot check balancing tokens, such as parenthesis. Therefore, this phase uses context-free grammar (CFG), which is recognized by push-down automata.
