Right now (please call me on this sometime, it'd help me) I'm working on a clone of Burp, the industry standard web penetration testing tool, in Cocoa. I started with RubyCocoa, but I've ditched it for Objective C. It is (surprisingly) liberating to work in C after spending a year in Ruby; any time something looks expensive or naive, you just tell yourself, "what I'm doing here can't possibly be more expensive than what MRI Ruby would have done", and you go about your day. Highly recommended. The last code I managed to publish was Ruckus: http://github.com/tqbf/ruckus/ http://github.com/tqbf/ruckus/ (a better description: http://wiki.github.com/tqbf/ruckus/crash-course http://wiki.github.com/tqbf/ruckus/crash-course) Ruckus is a Ruby DSL replacement for Peach Fuzz, Mike Eddington's famous Python fuzzer library. It is distinguished by being about 100 times slower, using a DSL instead of XML, and providing a DOM-style interface to any packet format (you can tag fields, arbitrarily nested in a tree structure, with classes and id's, and then fuzz them using CSS selectors). I have a JDWP JVM debugger (or rather a thin protocol driver) written in Ruckus if anyone's interested in seeing what it actually looks like. We never get to publish the actual protocols we build with this. My programming "day job" (I'm one of 4 developers on the project) is Playbook: http://runplaybook.com http://runplaybook.com
- yan 18y ago
  Never had I felt more like I was tricking software into doing what I want to do than when I was trying to use Peach. I mean Michael's a nice guy, but you email the peachfuzz list or him personally on issues you're having and he convinces you that it's you not using the tool correctly and that you really don't want the feature you're asking. Modifying code was hellish because it's just thousands of lines of kludge, written as far from Python's usual styles as possible. Good stuff on the Burp clone. Any plans to publish it eventually? -- As for me, the last project I was working on is a complex structure analyzer plug-in for HexFiend along with basic plug-in functionality to support it.
  - tptacek 18y ago
    I'm planning on wiring Ruckus into Hexfiend, so you can highlight hex characters Ethereal-style and using CSS selectors from packet formats. I don't know what I'm going to do with the Burp clone, but if you ask me for it, I'll hand it over. =)
    - yan 18y ago
      I'd like to take a look at the burp clone, not sure if I'll contribute. Do you want help on wiring to hexfiend?
      - tptacek 18y ago
        I just used RubyCocoa, but I haven't done much of the UI stuff yet. My contact info's in my profile, though.

I'm working on a programming language that has builtin support for reloading code at runtime. It'll also support various ways of modifying code at runtime, like with visual interfaces. The primary usage is for making interactive graphical apps, like games. Intro is here: http://andyfischer.github.com/circa/intro.html http://andyfischer.github.com/circa/intro.html code is here: http://github.com/andyfischer/circa/tree/master http://github.com/andyfischer/circa/tree/master
- bsaunder 18y ago
  I've prototyped a similar concept in Perl (still a bit rough). I think this is a powerful concept.
- cool-RR 18y ago
  Wouldn't it be better to modify an existing, popular language to support this feature?
  - barrybe 18y ago
    It would be better, but I want to do some cool things that I'm not sure if I can support in an existing language. One thing is automatically preserving state across a reload. This is really hard if I allow the programmer to store state any way that they want- I can't tell which things I should preserve. So the language forces the programmer to declare their stateful things in a special way. Another thing is introspecting on code. I want to be able to click an image and then see all of the calculations that went in to that image's position (maybe so that I can change them). But this is pretty hard in most languages. Aliasing makes it hard. So this language discourages operations which are hard to introspect. So I could theoretically support Ruby or something, but it would turn out to be "not really Ruby", because there would be a lot of stuff you wouldn't be allowed to do.

      Unity is a game engine that uses Mono as its scripting languages. You can recompile on the fly (you frequently play the game in-IDE during development).

Right now I'm working on adding extensions to Chrome. The majority of the system is in this directory: http://src.chromium.org/viewvc/chrome/trunk/src/chrome/browser/extensions/ http://src.chromium.org/viewvc/chrome/trunk/src/chrome/brows... And what I've been working on most recently is the code that renders little HTML-based toolbars. My most recent change fixed a race that caused them to not render correctly on the first run: http://src.chromium.org/viewvc/chrome?view=rev&revision=14914 http://src.chromium.org/viewvc/chrome?view=rev&revision=... I think one of the coolest parts of the system is the way that api methods are routed from JS running in extension processes to the browser process and back. The core of that is here: http://src.chromium.org/viewvc/chrome/trunk/src/chrome/browser/extensions/extension_function_dispatcher.h?view=markup http://src.chromium.org/viewvc/chrome/trunk/src/chrome/brows...

I've been working on my Z-Machine interpreter library again. It basically started as a project to turn Frotz into a Ruby extension (Frotz, probably the most popular interpreter, is written in C). The code has undergone quite a few transformations now. Frotz uses a lot of static memory -- it's basically setup to run a single zcode program at a time. Which makes sense, of course. For my library, I wanted to be able to run more than one program (or multiple copies of the same program) at the same time. So, I basically rewrote the core of Frotz. All the memory for a Z-Machine is broken up into structs which are passed around. There were some fun memory management issues related to running multiple programs. The typical zcode program consists mostly of static memory (lots and lots of strings and code), so that static memory can be shared between programs. I have a test where I load something like 100,000 copies of minizork into memory and the process size "only" jumps to 118MB. Of course, normal code doesn't need that many simultaneous Z-Machine instances so garbage collection keeps memory pretty reasonable. Last time I worked on dorothy, I setup a demo webapp here: http://ifrotz.org http://ifrotz.org Which illustrates why I wanted to be able to run multiple programs. The demo runs minizork, dynamic memory is dumped and restored between requests. The hints, exits, and history feature is possible because the server "listens in" on your game and the games others have played. Lately I've been working on more memory inspection stuff, and now I have to work on some of the unfinished Z-Machine features (I've only implemented the v3 screen model). The code is on Github: http://github.com/eki/dorothy/tree/master http://github.com/eki/dorothy/tree/master

Mentioned in some comment thread, but I just fixed LuckyTubes (http://www-personal.umich.edu/~swolchok/luckytubes/ http://www-personal.umich.edu/~swolchok/luckytubes/), my YouTube search/download/rip tool using youtube-dl and ffmpeg, to correctly rip the audio stream from the downloaded video without transcoding to 64 kbps MP3 (oops). It's called LuckyTubes because it does a "feeling lucky" YT search for the terms you type in. Code is at http://github.com/swolchok/luckytubes/ http://github.com/swolchok/luckytubes/ . No code for this project, but UmBus (http://mbusreloaded.com/umbus http://mbusreloaded.com/umbus) is my pet project to let UMich students get the GPS-estimated arrival times for the uni buses via text messaging. If I weren't so late to the party, I would try to compete with www.nextbus.com .

I'm actually looking for a new name for my project, so maybe someone here will have a good idea? It's a framework for writing, running and analyzing simulations. It could take any kind of simulation: Physics, game theory, epidemic spread, electronics, whatever. It's in Python. This is where it currently lives: http://github.com/cool-RR/physicsthing/tree/master http://github.com/cool-RR/physicsthing/tree/master (Keep in mind it's still a very young project) The readme there was written when I had mostly physics simulations in mind. Now I've generalized the project to take any kind of simulation. I'll update the readme soon to reflect that, but I would really like to find a good name. Maybe something with a suffix or prefix of "Sim", but maybe not. Anyone has any ideas?

I'm working on an interactive fiction framework with a web framework flavour. It's my first Ruby project and depends on Shoes for cross-platform UI. Defining rooms, items, and non-player characters is done in YAML. I'm about midway through the project and, as a test and demo for the platform, am converting the 1978 game "Pirate Adventure" to the framework. Once the framework is done my partner and I plan to use it to create an adventure game based on the fashion world. This will inevitably lead to a movie deal and untold riches. All in all, it has been fun, educational, and a nice break from my day job wrangling Drupal. The code (so far) lives here: http://github.com/mcantelon/fashion-quest/tree/master http://github.com/mcantelon/fashion-quest/tree/master

Right now I'm working on a natural language task management system. Basically you enter something like "12 page paper in project hist201, due apr 23 est. 8h high priority" and it understands what the hell you're trying to say: project, deadline, estimated time, priority. It also checks similar tasks (using naive Bayesian classifiers) and gets you a probability distribution of velocities (estimated / actual / relevance for a word), and supposedly, but I am still working on it, will show you a probability of finishing it on time given past history of similar workload. The goal is to be able to either Tweet your new tasks, add them in bulk (several lines), or even do something like "http://taskulus.com/12 http://taskulus.com/12 page paper in project hist201 due apr 23 est 8h high priority" and then receive a lot of analysis.

Zak 18y ago
I'm working on implementing a hyperspatial text classifier in Haskell. It's conceptually similar to the hyperspace classifier in CRM114 (essentially a weighted nearest-neighbor search), but shouldn't crash as much or corrupt its data files. I've thought of some interesting problems to point a fast and effective classifier at that aren't spam detection. I'm also working on a library/framework in Clojure for apps that process a folder full of files in some way. The idea grew out of a Clojure program I wrote to make a folder full of images greyscale (http://github.com/zakwilson/imagesieve/tree/master http://github.com/zakwilson/imagesieve/tree/master).
- mahmud 18y ago
  Zak, by classifier I hope you mean "categorizer". i.e. given a text and a list of categories, return which categories the text belongs to, along with a confidence number. If so, I say chase that thought a bit. You might save me from actually messing with NLP.
  - Zak 18y ago
    Yes, I do. The usage is essentially identical to the Bayesian probability classifiers commonly used for spam detection. I compared several of the classifiers available in CRM114 and found hyperspace to be the most accurate as well as being much faster when checking a large number of categories.
    - mahmud 18y ago
      Amazing. This is pretty cool :-) The thing is 100% statistical right? It doesn't know anything about the grammar of a natural language (say, English.) right?
      - Zak 18y ago
        It's entirely non-statistical. It works by measuring the Hamming distance between samples using features consisting of single tokens, sequences of tokens and sequences of tokens with gaps. For example: The The quick The quick brown The quick ... jumped would all be features of the input "The quick brown fox jumped over the lazy dog". It doesn't know anything about grammar, though as a performance optimization it might be useful to limit the length of features to detectable sentence boundaries. I intend to make that behavior optional.

- humbledrone 18y ago
  Git won me over when I found out that I could make all kinds of commits willy-nilly. I make a lot of small commits to my local repo throughout the day. At the end of the day I then take the time to go through them, merging related commits and removing stupid commits before I send my changes upstream. I've found that it's much easier to avoid breaking the build this way.
  - icefox 18y ago
    Another way to not break the build is to add a local git hook that compiles your project before allowing a commit. Assuming you compiled and tested your change already (you did right... :) the compile hook will take no time at all. Using this I have only commited broken builds once or twice when it built on my macbook, but not on Linux (case insensitive file system) Wrote up more details on hooks along with some examples here: http://benjamin-meyer.blogspot.com/2008/10/git-hooks.html http://benjamin-meyer.blogspot.com/2008/10/git-hooks.html

I'm working on improving eventlet: http://devel.ag-projects.com/~denis/eventlet/ http://devel.ag-projects.com/~denis/eventlet/ Eventlet is a networking library that uses greenlet, Python implementation of coroutines [http://codespeak.net/py/0.9.2/greenlet.html http://codespeak.net/py/0.9.2/greenlet.html] to handle asynchronous events in a synchronous way. Greenlet can be thought as an analogue to Python's enhanced generator, however, without "yield" keyword and the limitations it brings. For the applications that are network-bounded it effectively brings Erlang-like scalability in Python: you can spawn as many greenlets as you like (they're cheap) (e.g. one or several per incoming connection), control their execution, etc. If that sounds unclear, just look at the examples: http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/tip/examples/connect.py http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/t... http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/tip/examples/twisted_server.py http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/t... http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/tip/examples/ http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/t... Compared to the original eventlet (home - http://wiki.secondlife.com/wiki/Eventlet http://wiki.secondlife.com/wiki/Eventlet) our branch has - a number of bugs fixed and "onions" removed - twisted integration - you can use any twisted reactor or twisted protocol or any other feature you like (this part is heavily influenced by corotwine) - proc module for advanced coroutine control (spawn, link, waitall, etc)

A .NET interpreter for embedded/constrained systems where MS.NET or Mono aren't suitable: http://www.dotnetanywhere.org/ http://www.dotnetanywhere.org/ It now implements most of the core .NET 2.0 spec, a usable subset of the base class library, and an implementation of a Graphics device suitable for embedded devices. Not the fastest of .NET runtimes, but its disk/memory footprint is surprisingly small, and it (mostly) works!

Last night, I was browsing the Digital Mars D compiler source to see how they detect and convert files in all the various UTF encodings to UTF-8. This is for a C++ pre-processor that I'm writing in D. I'm also trying to get a basic OGRE 3D app up and running on my MacBookPro. I want to use D + OGRE to build my personal editor / IDE.

For the last 6 months or so I've been working on a 'wikipedia for images' type site. I'm trying to fix all the UI deficiencies that bug me about other image sites. As a personal project with no deadline I've had a lot of fun premature-optimising the crap out of it! For example the thumbnails are in strips of 50 for a huge reduction in http requests. Here's the test set I've been using- http://imagecorpus.com/marylin-monroe http://imagecorpus.com/marylin-monroe My plan is to initially scrape a lot of hard-to-browse public domain image sets, for example the Library of Congress daguerreotype collection http://lcweb2.loc.gov/ammem/daghtml/daghome.html http://lcweb2.loc.gov/ammem/daghtml/daghome.html. And then I'll solicit contributions from the public to bulk it out. I was going to wait till I was ready to launch before posting here, but that could be a while... Any criticism/suggestions or offers to help are very welcome!

Unfortunately, no code to show off but... I'm working on a site for my wife where she and her friends can post photos of themselves trying on the same outfit. I've been wanting to learn Ruby on Rails so I've been playing around with it the past couple weeks. Domain is bought, code sort of works but needs a lot of love (and javascript, ruby magic, a design) before it'll be ready to launch. Hopefully I'll get motivated and get something out there shortly. To be honest, I've been more interested in Rails and Capistrano/Deprec than the project itself. Bought a 256mb slice at SliceHost and have been reloading the thing every week playing with configurations.

A very basic embedded operating system for an ARM7-based microcontroller. I'm still in the early stages. I have no illusions that I'm going to write anything better than the other RTOSs out there; it's just for the kicks of working on the bare metal. Sort of exhilarating to apply voltage to a microcontroller, and know that only _your_ instructions are running. A number of EE/CS programs have a course where you do this over a semester - I'm afraid I'm going to take a while longer on my own!

Right now (please call me on this sometime, it'd help me) I'm working on a clone of Burp, the industry standard web penetration testing tool, in Cocoa. I started with RubyCocoa, but I've ditched it for Objective C. It is (surprisingly) liberating to work in C after spending a year in Ruby; any time something looks expensive or naive, you just tell yourself, "what I'm doing here can't possibly be more expensive than what MRI Ruby would have done", and you go about your day. Highly recommended. The last code I managed to publish was Ruckus: http://github.com/tqbf/ruckus/ http://github.com/tqbf/ruckus/ (a better description: http://wiki.github.com/tqbf/ruckus/crash-course http://wiki.github.com/tqbf/ruckus/crash-course) Ruckus is a Ruby DSL replacement for Peach Fuzz, Mike Eddington's famous Python fuzzer library. It is distinguished by being about 100 times slower, using a DSL instead of XML, and providing a DOM-style interface to any packet format (you can tag fields, arbitrarily nested in a tree structure, with classes and id's, and then fuzz them using CSS selectors). I have a JDWP JVM debugger (or rather a thin protocol driver) written in Ruckus if anyone's interested in seeing what it actually looks like. We never get to publish the actual protocols we build with this. My programming "day job" (I'm one of 4 developers on the project) is Playbook: http://runplaybook.com http://runplaybook.com

yan 18y ago
Never had I felt more like I was tricking software into doing what I want to do than when I was trying to use Peach. I mean Michael's a nice guy, but you email the peachfuzz list or him personally on issues you're having and he convinces you that it's you not using the tool correctly and that you really don't want the feature you're asking. Modifying code was hellish because it's just thousands of lines of kludge, written as far from Python's usual styles as possible. Good stuff on the Burp clone. Any plans to publish it eventually? -- As for me, the last project I was working on is a complex structure analyzer plug-in for HexFiend along with basic plug-in functionality to support it.
- tptacek 18y ago
  I'm planning on wiring Ruckus into Hexfiend, so you can highlight hex characters Ethereal-style and using CSS selectors from packet formats. I don't know what I'm going to do with the Burp clone, but if you ask me for it, I'll hand it over. =)
  - yan 18y ago
    I'd like to take a look at the burp clone, not sure if I'll contribute. Do you want help on wiring to hexfiend?

I'm working on a programming language that has builtin support for reloading code at runtime. It'll also support various ways of modifying code at runtime, like with visual interfaces. The primary usage is for making interactive graphical apps, like games.

cool-RR 18y ago
Wouldn't it be better to modify an existing, popular language to support this feature?
- barrybe 18y ago
  It would be better, but I want to do some cool things that I'm not sure if I can support in an existing language. One thing is automatically preserving state across a reload. This is really hard if I allow the programmer to store state any way that they want- I can't tell which things I should preserve. So the language forces the programmer to declare their stateful things in a special way. Another thing is introspecting on code. I want to be able to click an image and then see all of the calculations that went in to that image's position (maybe so that I can change them). But this is pretty hard in most languages. Aliasing makes it hard. So this language discourages operations which are hard to introspect. So I could theoretically support Ruby or something, but it would turn out to be "not really Ruby", because there would be a lot of stuff you wouldn't be allowed to do.

The majority of the system is in this directory: http://src.chromium.org/viewvc/chrome/trunk/src/chrome/browser/extensions/ http://src.chromium.org/viewvc/chrome/trunk/src/chrome/brows...

I've been working on my Z-Machine interpreter library again. It basically started as a project to turn Frotz into a Ruby extension (Frotz, probably the most popular interpreter, is written in C). The code has undergone quite a few transformations now. Frotz uses a lot of static memory -- it's basically setup to run a single zcode program at a time. Which makes sense, of course. For my library, I wanted to be able to run more than one program (or multiple copies of the same program) at the same time. So, I basically rewrote the core of Frotz. All the memory for a Z-Machine is broken up into structs which are passed around. There were some fun memory management issues related to running multiple programs. The typical zcode program consists mostly of static memory (lots and lots of strings and code), so that static memory can be shared between programs. I have a test where I load something like 100,000 copies of minizork into memory and the process size "only" jumps to 118MB. Of course, normal code doesn't need that many simultaneous Z-Machine instances so garbage collection keeps memory pretty reasonable. Last time I worked on dorothy, I setup a demo webapp here: http://ifrotz.org http://ifrotz.org Which illustrates why I wanted to be able to run multiple programs. The demo runs minizork, dynamic memory is dumped and restored between requests. The hints, exits, and history feature is possible because the server "listens in" on your game and the games others have played. Lately I've been working on more memory inspection stuff, and now I have to work on some of the unfinished Z-Machine features (I've only implemented the v3 screen model). The code is on Github: http://github.com/eki/dorothy/tree/master http://github.com/eki/dorothy/tree/master

I'm actually looking for a new name for my project, so maybe someone here will have a good idea? It's a framework for writing, running and analyzing simulations.

This is where it currently lives: http://github.com/cool-RR/physicsthing/tree/master http://github.com/cool-RR/physicsthing/tree/master (Keep in mind it's still a very young project) The readme there was written when I had mostly physics simulations in mind. Now I've generalized the project to take any kind of simulation. I'll update the readme soon to reflect that, but I would really like to find a good name. Maybe something with a suffix or prefix of "Sim", but maybe not. Anyone has any ideas?

I'm working on an interactive fiction framework with a web framework flavour. It's my first Ruby project and depends on Shoes for cross-platform UI. Defining rooms, items, and non-player characters is done in YAML. I'm about midway through the project and, as a test and demo for the platform, am converting the 1978 game "Pirate Adventure" to the framework. Once the framework is done my partner and I plan to use it to create an adventure game based on the fashion world. This will inevitably lead to a movie deal and untold riches.

Right now I'm working on a natural language task management system. Basically you enter something like "12 page paper in project hist201, due apr 23 est. 8h high priority" and it understands what the hell you're trying to say: project, deadline, estimated time, priority. It also checks similar tasks (using naive Bayesian classifiers) and gets you a probability distribution of velocities (estimated / actual / relevance for a word), and supposedly, but I am still working on it, will show you a probability of finishing it on time given past history of similar workload. The goal is to be able to either Tweet your new tasks, add them in bulk (several lines), or even do something like "http://taskulus.com/12 http://taskulus.com/12 page paper in project hist201 due apr 23 est 8h high priority" and then receive a lot of analysis.

Zak 18y ago

I'm working on implementing a hyperspatial text classifier in Haskell. It's conceptually similar to the hyperspace classifier in CRM114 (essentially a weighted nearest-neighbor search), but shouldn't crash as much or corrupt its data files. I've thought of some interesting problems to point a fast and effective classifier at that aren't spam detection. I'm also working on a library/framework in Clojure for apps that process a folder full of files in some way. The idea grew out of a Clojure program I wrote to make a folder full of images greyscale (http://github.com/zakwilson/imagesieve/tree/master http://github.com/zakwilson/imagesieve/tree/master).

mahmud 18y ago
Zak, by classifier I hope you mean "categorizer". i.e. given a text and a list of categories, return which categories the text belongs to, along with a confidence number. If so, I say chase that thought a bit. You might save me from actually messing with NLP.
- Zak 18y ago
  Yes, I do. The usage is essentially identical to the Bayesian probability classifiers commonly used for spam detection. I compared several of the classifiers available in CRM114 and found hyperspace to be the most accurate as well as being much faster when checking a large number of categories.
  - mahmud 18y ago
    Amazing. This is pretty cool :-) The thing is 100% statistical right? It doesn't know anything about the grammar of a natural language (say, English.) right?
    - Zak 18y ago
      It's entirely non-statistical. It works by measuring the Hamming distance between samples using features consisting of single tokens, sequences of tokens and sequences of tokens with gaps. For example: The The quick The quick brown The quick ... jumped would all be features of the input "The quick brown fox jumped over the lazy dog". It doesn't know anything about grammar, though as a performance optimization it might be useful to limit the length of features to detectable sentence boundaries. I intend to make that behavior optional.

humbledrone 18y ago
Git won me over when I found out that I could make all kinds of commits willy-nilly. I make a lot of small commits to my local repo throughout the day. At the end of the day I then take the time to go through them, merging related commits and removing stupid commits before I send my changes upstream. I've found that it's much easier to avoid breaking the build this way.
- icefox 18y ago
  Another way to not break the build is to add a local git hook that compiles your project before allowing a commit. Assuming you compiled and tested your change already (you did right... :) the compile hook will take no time at all. Using this I have only commited broken builds once or twice when it built on my macbook, but not on Linux (case insensitive file system) Wrote up more details on hooks along with some examples here: http://benjamin-meyer.blogspot.com/2008/10/git-hooks.html http://benjamin-meyer.blogspot.com/2008/10/git-hooks.html

I'm working on improving eventlet: http://devel.ag-projects.com/~denis/eventlet/ http://devel.ag-projects.com/~denis/eventlet/ Eventlet is a networking library that uses greenlet, Python implementation of coroutines [http://codespeak.net/py/0.9.2/greenlet.html http://codespeak.net/py/0.9.2/greenlet.html] to handle asynchronous events in a synchronous way. Greenlet can be thought as an analogue to Python's enhanced generator, however, without "yield" keyword and the limitations it brings. For the applications that are network-bounded it effectively brings Erlang-like scalability in Python: you can spawn as many greenlets as you like (they're cheap) (e.g. one or several per incoming connection), control their execution, etc. If that sounds unclear, just look at the examples: http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/tip/examples/connect.py http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/t... http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/tip/examples/twisted_server.py http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/t... http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/tip/examples/ http://devel.ag-projects.com/~denis/cgi-bin/hgweb.cgi/file/t... Compared to the original eventlet (home - http://wiki.secondlife.com/wiki/Eventlet http://wiki.secondlife.com/wiki/Eventlet) our branch has - a number of bugs fixed and "onions" removed - twisted integration - you can use any twisted reactor or twisted protocol or any other feature you like (this part is heavily influenced by corotwine) - proc module for advanced coroutine control (spawn, link, waitall, etc)

My project is InfoML (http://infoml.org/ http://infoml.org/), a proposed standard for storing "chunks" of (human-readable) text and annotating it with various useful metadata, including tags and bibliographic information. I hope there will eventually be a community of developers who will find InfoML useful and will build a variety of software tools for manipulating data stored in this format.

chriseppstein 18y ago
I think a microformat schema or schemas would be more beneficial for this kind of data.

Bingo! A well written tool is a huge necessity.

I've been working on a couple of javascript projects. The big one is best described as iTunes for Flash games - a rich internet app for creating and managing a library of Flash games - http://www.webalon.com/gamemanager/ http://www.webalon.com/gamemanager/ The second thing that I have been working on is a resizeable javascript image carousel featuring a variety of transitions - you can see it in action at: http://www.webalon.com http://www.webalon.com I hope to open source the latter when complete

bgnm2000 18y ago
You've created some really awesome stuff!
- alexkearns 18y ago
  Thanks mate. Glad you liked it. You working on anything interesting?

csbartus 18y ago

Right now I envy all of you :D I wish I could list here my own project too but lately I just take input all day without producing anything ...

At work I've just been writing a testing framework in Matlab (mostly for fun, but it actualy seems to work!). And I have next week off, so I thought I'd have a go at building something in rails.

danohuiginn 18y ago

Two projects. One is scraping and indexing data on corporations registered in tax havens, mainly for the purpose of helping transparency researchers follow the activities and connections of businessmen, politicians, etc. I've done Panama, and am now working on a couple of others: http://ohuiginn.net/panama http://ohuiginn.net/panama http://www.ohuiginn.net/mt/2008/12/opening_up_a_tax_haven.html http://www.ohuiginn.net/mt/2008/12/opening_up_a_tax_haven.ht... The second project is building a decent interface to the first edition of the Oxford English Dictionary. The current edition is online, charging ~$200/year for access, but the first edition is out of copyright, sitting on archive.org, and just waiting for somebody to make it accessible without the need to download several GB of scans.

biohacker42 18y ago
Those are both great ideas. Please consider a donate doohickey for each project. I would gladly contribute to both.

I'm currently working on a mp3tag-like tag editor for Linux called puddletag which you can find at puddletag.sourceforge.net. Don't download it yet though. I'm releasing a update tomorrow with a large number of bugfixes and improvements.

I'm developing a CSS generator called Stylish. It's pretty rudimentary right now, but progress is relatively quick (for me, anyway). Code: http://github.com/ionfish/stylish http://github.com/ionfish/stylish Docs: http://ionfish.github.com/stylish http://ionfish.github.com/stylish

mnemonik 18y ago
You might want to consider naming it something else since there is already a firefox addon called stylish: https://addons.mozilla.org/en-US/firefox/addon/2108 https://addons.mozilla.org/en-US/firefox/addon/2108 Yes they are different products but I still think there might be some confusion...
- ionfish 18y ago
  There are a limited number of good names in the world! :) To nitpick slightly, I wouldn't call my library a product. If you have any suggestions for alternative names I'd be happy to hear them.
  - mnemonik 18y ago
    I guess that the firefox addon isn't really a product either; it was a late night. Here are a few names off the top of my head: * Stylee * EaseSS (Easy Style Sheets? :)) * Flair ease * Stylify (Style-ify, Styleify) * Chic Sheets Good luck and happy coding!

Another programming language: http://www-student.cs.york.ac.uk/~anc505/code/hasp/hasp.html http://www-student.cs.york.ac.uk/~anc505/code/hasp/hasp.html I'm not doing any fancy compiler stuff - the target language is Haskell so that's all done for me. *Edit: And I should probably say something about it :) Its an s-expression based language so it looks like a Lisp and you can use macros on it, it also reads by indentation if you want it to look like Python, and then the rest of it just comes from Haskell :)

I'm working on a AWS stack based web crawler. It uses S3 and SimpleDB to coordinate instances. It's implemented in Python/Twisted, and extensible via plugins. It has a low cost of entry in terms of code and costs and scales horizontally, so it's useful for all sorts of aggregation.

Back-testing a support vector machine -based text classification system that models daily stock news, looking for mispriced volatility. A big stealth project, with just the Ruby option pricer here: http://tinyurl.com/chmk7p http://tinyurl.com/chmk7p Need much more realism than Black-Scholes for the model training!

A .NET interpreter for embedded/constrained systems where MS.NET or Mono aren't suitable: http://www.dotnetanywhere.org/ http://www.dotnetanywhere.org/ It now implements most of the core .NET 2.0 spec, a usable subset of the base class library, and an implementation of a Graphics device suitable for embedded devices. Not the fastest of .NET runtimes, but its disk/memory footprint is surprisingly small, and it (mostly) works!

potatolicious 18y ago
I will have to give this a shot :) I've been looking for good high level ways to program embedded boards (like the Beagleboard)... definitely going to give this a try.

I'm working on the API for my PDF/Web Form site http://www.doculicious.com http://www.doculicious.com. The initial release will allow reading of saved entries and posting of new entries. This is cool, 'cos it will let people use their own HTML forms to submit data and create PDF's from the templates they've created.

Last night, I was browsing the Digital Mars D compiler source to see how they detect and convert files in all the various UTF encodings to UTF-8. This is for a C++ pre-processor that I'm writing in D. I'm also trying to get a basic OGRE 3D app up and running on my MacBookPro. I want to use D + OGRE to build my personal editor / IDE. It has to be PC/Mac/Linux. I'm slowly finishing an update to my iPhone app, iLightning http://www.shinyfish.com/ilightning http://www.shinyfish.com/ilightning. Right now I'm working on some animated transitions between the main view and the prefs screen.

potatolicious 18y ago
Your domain name - are you using neural networks for your recommendations?
- maryrosecook 18y ago
  Ah, no. I bought the domain name because, for a while, I was going to call my new band The Perceptron. I ended up calling it something else, but figured I could reuse the domain for the site.

For the last 6 months or so I've been working on a 'wikipedia for images' type site. I'm trying to fix all the UI deficiencies that bug me about other image sites. As a personal project with no deadline I've had a lot of fun premature-optimising the crap out of it! For example the thumbnails are in strips of 50 for a huge reduction in http requests. Here's the test set I've been using- http://imagecorpus.com/marylin-monroe http://imagecorpus.com/marylin-monroe My plan is to initially scrape a lot of hard-to-browse public domain image sets, for example the Library of Congress daguerreotype collection http://lcweb2.loc.gov/ammem/daghtml/daghome.html http://lcweb2.loc.gov/ammem/daghtml/daghome.html. And then I'll solicit contributions from the public to bulk it out. I was going to wait till I was ready to launch before posting here, but that could be a while... Any criticism/suggestions or offers to help are very welcome!

abyssknight 18y ago

Unfortunately, no code to show off but... I'm working on a site for my wife where she and her friends can post photos of themselves trying on the same outfit. I've been wanting to learn Ruby on Rails so I've been playing around with it the past couple weeks. Domain is bought, code sort of works but needs a lot of love (and javascript, ruby magic, a design) before it'll be ready to launch. Hopefully I'll get motivated and get something out there shortly. To be honest, I've been more interested in Rails and Capistrano/Deprec than the project itself. Bought a 256mb slice at SliceHost and have been reloading the thing every week playing with configurations.

A very basic embedded operating system for an ARM7-based microcontroller. I'm still in the early stages. I have no illusions that I'm going to write anything better than the other RTOSs out there; it's just for the kicks of working on the bare metal. Sort of exhilarating to apply voltage to a microcontroller, and know that only _your_ instructions are running. A number of EE/CS programs have a course where you do this over a semester - I'm afraid I'm going to take a while longer on my own!

No code to show, but I'm working on a one-off remote controller for pole cameras for an indie filmmaker. It should enable "aerial" shots like the pros, but at a small fraction of the cost. Version 1 is in testing.

A new type of database where the schema is open and flexibly restructures depending on the data you put in. The change allows anyone, from 8 to 80, to structure their data without knowing that's what they're doing.

Webapp, will prototype with Drupal, so no real hacking at first. Counts? Then Railsification. Me: Industrial/UX designer (and food lover) who loves DIY, but needs products for laymen, not just dev.s. Story: Our local (Maine) farmers market needs a site. Hell, why not build a build-your-own farmers market site platform/app? So that's the deal. Comments, recipes welcome.
