A tale of three code generators

Posted 20 Feb 2009 at 17:00 UTC (updated 21 Feb 2009 at 10:51 UTC) by aph

At FOSDEM 2009, Gary Benson of Red Hat presented Shark. (Slides at http://gbenson.net/wp-content/uploads/2009/02/fosdem-2009.pdf) Shark is a port of OpenJDK that uses LLVM to do JIT code generation. While Shark is pretty fast when compared with OpenJDK's C++ interpreter, it's still quite a lot slower than gcj. gcj is a fairly straightforward bytecode->native compiler and doesn't use many of the Java-specific optimizations in HotSpot, so I was of the opinion that Shark and gcj ought to be similar in speed. So, I wanted to find out why Shark was slower than gcj.

Welcome to the SAMBA Domain: 10 years on

Posted 13 Feb 2009 at 21:22 UTC (updated 13 Feb 2009 at 21:59 UTC) by lkcl

The 10th anniversary of "Welcome to the SAMBA Domain" quietly passed on Thursday 28th of August, 2007, without acknowledgement. When Paul Ashton and Luke Leighton initially reverse-engineered and published the NT Domains protocol, the floodgates were opened to both Free Software and Proprietary CIFS vendors to interoperate with Microsoft's flagship product, Windows NT, at an unprecedented level.

The anticipated reprisals from Microsoft did not happen: incredibly, instead, quiet mutual respect and cooperation crystallised the CIFS protocols into formal specifications (some of which were quietly handed out, whilst others had to wait until they were prised from Microsoft's fingers by the U.S. Dept of Justice and the E.U Commission).

In the intervening eleven years, an enormous amount has been achieved, yet, frustratingly, an enormous amount has not. This article outlines the accomplishments to date, and highlights the incredible things that could be achieved if some specific strategic inter-project free software cooperation took place. Also outlined are some hints as to how that can be accomplished, citing examples of prior proven work in which it has already been achieved, but not yet adopted.

The Netbook Windfall

Posted 12 Feb 2009 at 17:11 UTC by dmarti

Joe Wein covers Windows 7 versus Linux on netbooks. "Does it really matter to Microsoft shareholders and employees if the 21 million or so netbooks expected to be sold this year (and the even bigger numbers in 2010) will be running some version of Windows or a version of Linux (which is free), if previously those buyers would have picked up a more powerful machine that netted Microsoft $40-$100 per license?"

Don Marti offers his insights into the Netbook and the Linux combination.

GitTorrent, The Movie

Posted 4 Dec 2008 at 15:56 UTC (updated 4 Dec 2008 at 18:22 UTC) by lkcl

Git promises to be a distributed software management tool, where a repository can be distributed. Yet, the mechanisms used to date to actually "distribute", such as rsync, http and ssh, are very much "single path" and centralised.

GitTorrent makes Git truly distributed. The initial plans are for reducing mirror loading, however the full plans include totally distributed development: no central mirrors whatsoever. PGP signing and other web-of-trust-based mechanisms will take over from protocols on ports (e.g. ssh) as the access control "clearing house".

The implications of a truly distributed revision control system are truly staggering: unrestricted software freedom; the playing field is levelled in so many ways, as "the web site" no longer becomes the central choke-point of control. This article will explain more fully some of these implications, not only from a technical perspective but also including the political implications for Software Freedom.

Blurring of MVC lines: Programming the Web Browser.

Posted 27 Nov 2008 at 17:06 UTC (updated 29 Nov 2008 at 10:35 UTC) by lkcl

When HTML first came out, browsers could have been called "Application Thin Clients", if the buzzword had been in use at the time. The introduction of javascript made it possible to execute code on the client, and this turned browsers into something much more than just a "display" mechanism.

Before Javascript, Web application development was simple: everything was done server-side. The concept of MVC - Model View Controller - was easy: the HTML was generated, and that was the view. With Javascript being a full-blown programming language, the lines are being blurred between which code is responsible for the View, the Controller and even the Model. The resultant split of responsibility across client and server in wildly diverse programming languages is driving many developers to alternative technologies such as Flash, and causing headaches for those Web developers who remain.

The key components of the solution - to allow the developer to create MVC applications in a single programming language, where at least the "View" source is extracted and compiled to Javascript and HTML - actually exist and are used in production environments, thanks to Google Web Toolkit and Pyjamas. RubyJS is well on the way, too.

The Great Wannabe Hacker Emblem Controversy

Posted 6 Nov 2008 at 05:18 UTC (updated 6 Nov 2008 at 18:22 UTC) by laburu

If you think a polemic about a symbol devised to represent people who mockingly declare themselves unworthy of displaying some other symbol designed to represent them [*breathe*] is much ado about nothing, we have something in common. It may be one of a very few things we have in common. Indeed, we are probably quite different, and I am sure I have not done enough to earn the privilege of being counted as one of you — regardless of who you are. That's because, as it turns out, one cannot earn membership in hackerdom.

Open Letter to Richard Stallman

Posted 4 Nov 2008 at 21:52 UTC by cdfrey

Dear Mr. Stallman,

I am writing to express my disappointment with the Free Software Foundation regarding the recent release of the GNU Free Documentation License version 1.3.

The new version 1.3 adds a new clause, section 11, which, according to the FAQ, allows wiki sites to relicense specific content from GFDL 1.3 to CC-BY-SA 3.0, for content added before November 1, 2008. They have this relicensing option until August 1, 2009.

This, in my view, is a serious moral mistake and breach of trust. Even if this new clause does no harm, it is still the wrong thing to do.

Understanding the ways of the Internet

Posted 31 Oct 2008 at 02:39 UTC by bibekpaudel

People have embraced the internet so much that even in a country like ours, Honorable Finance Minister (Dr. Baburam Bhattarai of CPN-Maoist) has a Facebook profile (looks genuine so far). He (or whoever maintains the profile on his behalf) regularly updates his status. Sometime back, while I was busy with work and couldn't catch up with news, his status updates served as a good substitute. He also posts pictures from events he attends. The most followed part, in my opinion, are the notes he posts to his profile- interviews, articles published in newspapers, political notes, and other pieces. The problem, as stated by many of his "friends" (well, facebook friends) is that he never replies (or interacts with) their queries and comments. There is a feature called "Facebook Page" that he could have used to update his "fans" (just another facebook word), without engendering expectations of interaction in them. There are other ways of avoiding interaction on the internet too. While I appreciate Dr. Bhattarai's efforts to make use of technology at a time when most Nepalese leaders struggle to use even the basic tools, I disagree with his mode of operation.

Enough Hot Air

Posted 28 Oct 2008 at 22:59 UTC by laburu

Once upon a time in the not-too-distant past, a hacker I know blogged about using object-oriented C to implement a lightweight imitation of some of C++'s features for his latest project; almost immediately, somebody saw fit to reward this charming piece of acceptably self-congratulatory writing with a stern and quite public deconstruction. Does this scene seem familiar? Why does this keep happening? And what, if anything, can we do about it? We can hardly hope to appease all of hackerdom's malcontent — but we can at least try to avoid stepping on each other's toes. Accordingly, this article will waste no time on a platitudinous condemnation of the surf-by put-down; rather, I wish to take a moment to reflect on what the hacker did to earn it, and to consider what he might have done (or, rather, not done) instead.

pyv8: python v8 bindings and a python-javascript compiler

Posted 28 Sep 2008 at 14:03 UTC (updated 28 Sep 2008 at 16:33 UTC) by lkcl

pyv8 is an experimental project to combine two-way python bindings to v8 with the python-to-javascript compiler from pyjamas. a simple test has shown a ten times performance increase of python code converted and executed as javascript, when compared to running the same program as python. (to be fair, cython gives a 100 times performance increase).

Software Freedom Day in Nepal

Posted 21 Sep 2008 at 20:02 UTC by mattl

Free and Open Source Software (FOSS) Community of Nepal (FOSS-Nepal) observed the fifth international Software Freedom Day today. The day was celebrated by over 500 different volunteer groups in 120 countries. The theme for this year's celebration of FOSS-Nepal was "Create, Share, Collaborate." Honourable Minister of Science and Technology, Ganesh Shah started the proceedings at Yala Maya Kendra in Patan, Kathmandu by unveiling a compilation of Free/Open Source Softwares in a CD named "Nirvikalpa." Honourable Minister also announced the launch of a web-portal named "Prasfutan." "Prasfutan" which means "blossoming" in English aims to provide a collaborative environment to a vast number of local talents in Nepal whose creativity has a reach only up to a limited audience comprising of their acquaintances. This is in sync with the theme of "Create, Share, Collaborate."
