Why's (Poignant) Guide to Ruby   25 Sep 04
[print link all ]

(Source: whytheluckystiff) The (Poignant) Guide is a new approach to teaching Ruby, emphasizing the lingual traits of Ruby and illustrating its uniqueness with comics, visual imagery, and songs with accompanying hand gestures.

This date marks the release of the first three chapters. Feel free to tell your friends and family (a.k.a. Slashdot) about the news. With enough input and support, this book could see completion by next year. Hopefully this is a step towards explaining to the world why Ruby is such an enticing and voluptuous gem to behold.

Go and enjoy the book

Okay, I’ll keep this short. If you want to read more about my motivation, head over to the announcement on my site. motivation

Root: An Object-Oriented Data Analysis Framework   25 Sep 04
[print link all ]

Sven C. Koehler, our hard-coding dataminer has sent me an email while his code was probably exploring the DNA of some beauty. I wonder whether it was the beauty the root-team uses in their logo? Hey, just because of the logo, one ought to give root a try.

 What I was impressed about:
 ``We started the ROOT project in the context of the NA49 experiment at
 CERN. NA49 generates an impressive amount of data, about 10 Terabytes
 of raw data per run.'';

 ``Thanks to the builtin CINT C++ interpreter the command language,
  the scripting, or macro, language and the programming language are
  all C++. The interpreter allows for fast prototyping of the macros
  since it removes the time consuming compile/link cycle. It also
  provides a good environment to learn C++. If more performance is
  needed the interactively developed macros can be compiled using a
  C++ compiler.'';
 ``The backbone of the ROOT architecture is a layered class
 hierarchy with, currently, around 310 classes grouped in about 24
 frameworks divided in 14 categories. This hierarchy is organized in
 a mostly single-rooted class library, that is, most of the classes
 inherit from a common base class TObject. While this organization
 is not very popular in C++, it has proven to be well suited for our
 needs (and indeed for almost all successful class libraries: Java,
 Smalltalk, MFC, etc)''.

WebDav in 10 minutes: HTTP gave you read, now DAV gives you write access   25 Sep 04
[print link all ]
The stated goal of the WebDAV (DAV) working group is (from the charter) to "define the HTTP extensions necessary to enable distributed web authoring tools to be broadly interoperable, while supporting user needs", and in this respect DAV is completing the original vision of the Web as a writeable, collaborative medium.

But, people working on DAV have had goals which extend beyond simple web page authoring. Some view DAV as a network filesystem suitable for the Internet, one that works on entire files at a time, with good performance in high-latency environments. Others view DAV as a protocol for manipulating the contents of a document management system via the Web. An important goal of DAV is to support virtual enterprises, being the primary protocol supporting a wide range of collaborative applications. Importantly, a major goal is the support of remote software development teams. A final goal of DAV is to leverage the success of HTTP in being a standard access layer for a wide range of storage repositories — HTTP gave them read access, while DAV gives them write access.

Well, the website clains WebDAV in 2 minutes .. I think 10-20 minutes is more realistic :-). A good starter.

Apache2 already comes with mod_dav.

Gametrak. is a new videogames controller, giving you precise and intuitive control in 3D space. link

Unlike cameras, infra-red, RF systems or tilt technologies, Gametrak. allows movement forwards and backwards as well as up, down, left and right.

With Gametrak you can punch your opponents with your hands; sports games let you pick up and play using real golf clubs or tennis racquets . you can even bounce virtual basketballs!

Designed and manufactured by In2Games, Gametrak will launch across Europe on PS2 in September 2004 with the revolutionary fighting game, Dark Wind.

Future Gametrak titles include golf, baseball, adventure, dancing and basketball games.


PlayStation 2: Computational Cluster   25 Sep 04
[print link all ]
The NCSA has constructed a PlayStation 2 Linux cluster as a test bench for scientific computation on "toy" hardware. The cluster consists of 65 compute nodes, 4 user login and development nodes, and 1 prototype node for software installation tests. All the nodes run the Sony Linux distribution for PlayStation 2. The compute nodes fill a 24-inch rack; 5 shelves at 13 per shelf (see left); link Looking forward to see such solutions for the new upcoming Playstation 3.

Comment: Microsoft's rush to next-gen could see the Xbox take a tumble   25 Sep 04
[print link all ]
(Source: Gamesindustry) from the article
 Microsoft may be making a colossal mistake by trying to force
 the industry into a next-generation cycle before it is ready
 to move. Sony, with its enormous dominance of the market, could
 probably just about get away with it - if it moved, the industry
 would have to move with it, however much it hated the idea. But
 Microsoft, still a relatively small player in the games industry,
 just doesn't look like a company that has the influence needed to
 force a shift like this. It may be backed up by the biggest
 software company in the world, but publishers will still look at
 the bottom line - in this case, installed base and cost of
 development - and base their decisions on that alone. Herein lies
 the arrogance; Microsoft isn't used to making decisions as an
 industry small-fry, and it's trying to act like an industry leader
 in an industry it simply doesn't lead.

Good to know: Offline NT Password & Registry Editor, Bootdisk / CD   25 Sep 04
[print link all ]
I’ve put together a single floppy or CD which contains things needed to edit the passwords on most systems.

The bootdisk supports standard (dual)IDE controllers, and most SCSI-controllers with the drivers supplied in a seperate archive below. It does not need any other special hardware, it will run on 486 or higher, with at least 32MB (I think) ram or more. Unsupported hardware: MCA, EISA, i2o may not work. Some newer IDE/SCSI-raid systems may not work either.

Tested on: NT 3.51, NT 4, Windows 2000 (except datacenter?), Windows XP (all versions), Window Server 2003 (at least Enterprise).

DANGER WILL ROBINSON! If used on users that have EFS encrypted files, and the system is XP or later service packs on win2k, all encrypted files for that user will be UNREADABLE! and cannot be recovered unless you remember the old password again


Napkin Look and Feel   25 Sep 04
[print link all ]
Now I did it. I made a Java category in this blog. I think like Paul Graham about Java and C#, but oh well ..

I coped this from: Napkin Look & Feel is a pluggable Java look and feel that looks like it was scrawled on a napkin. You can use it to make provisional work actually look provisonal, or just for fun.

The idea is to try to develop a look and feel that can be used in Java applications that looks informal and provisional, yet be fully functional for development. Often when people see a GUI mock-up, or a complete GUI without full functionality, they assume that the code behind it is working. While this can be used to sleazy advantage, it can also convince people who ought to know better (like your managers) that you are already done when you have just barely begun, or when only parts are complete.
