Dragon vs. Hydra - Competing Development Styles 90

peterofoz writes "You may recall that we discussed a company which was recruiting talent with a puzzle last December. This turned out to be n-Brain releasing a new product that allows multiple editors to modify the same code in real time to support the collaborative programming paradigm. Now they're back with another challenge: 'Are two heads really better than one? N-BRAIN, Inc. intends to definitively answer this question by sponsoring the Hydra Versus Dragon Coding Competition, a Reality TV-style battle between the world's finest software developers.' Mark June 23rd on your calendars." While n-Brain clearly intends this to promote their software, it will be interesting to see if the competition results support their theory of collaborative development.

Keeping Customer From Accessing My Database? 567

cyteen02 writes "We run a data processing and tracking system for a customer in the UK. We provide a simple Web site where the customer can display the tracking data held in our Oracle database. From these screens they can query based on a combination of 15 different data fields, so it's pretty flexible. We also provide a csv report overnight of the previous day's data processing, which they can load into their own SQL Server database and produce whatever reports they want. Occasionally they also want one-off specific detailed reports, so we write the SQL for that and send them the results in an Excel format spreadsheet. This all ticks along happily. However they have now asked for direct read-only access to our Oracle database, to be able to run ad-hoc queries without consulting us. As a DBA, my heart sinks at the thought of amateurs pawing through my database. Unfortunately, 'because you are stupid' is not considered a valid business reason to reject their request. So can any Slashdotters assist me in building my case to restrict access? Have you experienced a similar situation? Have you had to support this sort of end user access? How would you advice me to keep my customer away from my precious tables?"

Code Quality In Open and Closed Source Kernels 252

Diomidis Spinellis writes "Earlier today I presented at the 30th International Conference on Software Engineering a research paper comparing the code quality of Linux, Windows (its research kernel distribution), OpenSolaris, and FreeBSD. For the comparison I parsed multiple configurations of these systems (more than ten million lines) and stored the results in four databases, where I could run SQL queries on them. This amounted to 8GB of data, 160 million records. (I've made the databases and the SQL queries available online.) The areas I examined were file organization, code structure, code style, preprocessing, and data organization. To my surprise there was no clear winner or loser, but there were interesting differences in specific areas. As the summary concludes: '..the structure and internal quality attributes of a working, non-trivial software artifact will represent first and foremost the engineering requirements of its construction, with the influence of process being marginal, if any.'"

QGtkStyle Offers Native Gtk Look For Qt Programs 64

sekra writes "A new project called QGtkStyle by Trolltech Labs gives Qt4 based applications the possibility to integrate natively into Gtk based desktops like Gnome or Xfce. Instead of simply imitating Gtk styles QGtkStyle uses the Gtk theme engine directly. The project is still considered experimental, but is another step into better integration between Qt and Gtk applications. A project at Google Code has been set up as well." Anything that makes the various excellent Free software desktops work better together deserves kudos.

Colossus Cipher Challenge Winner On Ada 168

An anonymous reader writes "Colossus Cipher Challenge winner Joachim Schueth talks about why he settled on Ada as his language of choice to unravel a code transmitted from the Heinz Nixdorf Museum in Germany, from a Lorenz SZ42 Cipher machine (used by the German High Command to relay secret messages during the World War II). 'Ada allowed me to concisely express the algorithms I wanted to implement.'"

Targeting PocketPCs With Mono? 90

That's What She Said writes "I am a long time Mac user and, as most people like me, I have some particular problems with Microsoft technologies. I need to develop applications for the PocketPC platform (Windows CE and Windows Mobile), some simple data collection applications for barcode-enabled portable data terminals. Every device manufacturer on the market offer SDK's for .NET, so I believe this is the way to go. I already tried Microsoft Visual Studio and I am having serious problems using the IDE. I simply don't understand it quite well. My programming experience comes from PHP and JavaScript, where all I needed was a simple text editor and to keep my work as tidy as I could. So, it seems that a full-fledged IDE is kind of scary to me or Visual Studio is not very good for beginners. I also want to keep my costs low and free alternatives are welcome." Read on for a bit more (below) on why TWSS is thinking about Mono as a development environment, and is seeking advice.

Recruitment Options For a Small-Scale FOSS Project? 210

thermian writes "I've been developing my open source project for several years now, and I've never found a solution to one fairly important issue. How can a small-scale project attract new members? My project is pretty specialist, (no URL, sorry, I can't afford to get my server nuked) and I find that while it gets a fair bit of use, most users come to my software out of a need to solve their problem, or use my tutorials to learn about the subject, and none seem inclined to stick around and help make the product better. This is a fairly serious problem for me now, because my software has recently been adopted by a university, and I'm just not in a position to manage the entire set of applications and update everything on my own. Just preparing a version for release to students has been especially hard. The open source maxim 'Many eyes make all bugs shallow' only works if those 'many eyes' are available. So do you have any suggestions as to how, and where, to find people who fancy joining open source projects?"

What Is the Oldest Code Written Still Running? 903

Consul writes "What is the oldest piece of code that is still in use today, that has not actually been retyped or reimplemented in some way? By 'piece of code,' I'm of course referring to a complete algorithm, and not just a single line." The question would have a different answer if emulation, in multiple layers, is allowed.
Security

How the NSA Took Linux To the Next Level 172

An anonymous reader brings us IBM Developerworks' recent analysis of how the NSA built SELinux to withstand attacks. The article shows us some of the relevant kernel architecture and compares SELinux to a few other approaches. We've discussed SELinux in the past. Quoting: "If you have a program that responds to socket requests but doesn't need to access the file system, then that program should be able to listen on a given socket but not have access to the file system. That way, if the program is exploited in some way, its access is explicitly minimized. This type of control is called mandatory access control (MAC). Another approach to controlling access is role-based access control (RBAC). In RBAC, permissions are provided based on roles that are granted by the security system. The concept of a role differs from that of a traditional group in that a group represents one or more users. A role can represent multiple users, but it also represents the permissions that a set of users can perform. SELinux adds both MAC and RBAC to the GNU/Linux operating system."

The 25-Year-Old BSD Bug 213

sproketboy writes with news that a developer named Marc Balmer has recently fixed a bug in a bit of BSD code which is roughly 25 years old. In addition to the OSnews summary, you can read Balmer's comments and a technical description of the bug. "This code will not work as expected when seeking to the second entry of a block where the first has been deleted: seekdir() calls readdir() which happily skips the first entry (it has inode set to zero), and advance to the second entry. When the user now calls readdir() to read the directory entry to which he just seekdir()ed, he does not get the second entry but the third. Much to my surprise I not only found this problem in all other BSDs or BSD derived systems like Mac OS X, but also in very old BSD versions. I first checked 4.4BSD Lite 2, and Otto confirmed it is also in 4.2BSD. The bug has been around for roughly 25 years or more."

The Future of Subversion 173

sciurus0 writes "As the open source version control system Subversion nears its 1.5 release, one of its developers asks, what is the project's future? On the one hand, the number of public Subversion DAV servers is still growing quadratically. On the other hand, open source developers are increasingly switching to distributed version control systems like Git and Mercurial. Is there still a need for centralized version control in some environments, or is Linus Torvalds right that all who use it are 'ugly and stupid'?" The comments on the blog post have high S/N.

Data Mining In Law Enforcement 148

jcatcw points out a blog entry by Scott McPherson, CIO for the Florida House of Representatives. McPherson condemns the state of data sharing and data mining in law enforcement, saying that the US causes itself a great deal of trouble by focusing more on "antiterror armor and nuke-sniffing devices" than a useful information distribution network. He discusses a few such projects, and how they could have directly affected the events of 9/11. Quoting: "One of those ingenious things that actually worked, Seisint founder Hank Asher's brilliant MATRIX system, remains mired in controversy and politics. Hank showed me MATRIX just a few short weeks after the 9/11 attacks. Using law enforcement data and commercial data, all of the commercial data available in the public domain, Asher's query produced [hijacker Mohamed] Atta's photo -- and about 80 others, many of them fellow 9/11 hijackers, many of them associates of the 9/11 hijackers. It was simple data mining and algorithms, and none of the information was obtained illegally."

Ars Technica has an in-depth look at the release, which include an integrated WebKit-based HTML rendering engine, the new Phonon multimedia framework, support for Windows CE, and significant improvements to the QGraphicsView system. 'Qt 4.4 brings a lot of rich new capabilities to the toolkit that are sure to please open source and commercial software developers. It sounds like Trolltech already has some nice plans for Qt 4.5, and we will hopefully get to hear more about the long-term roadmap after Nokia completes its acquisition.'"

MySQL Reverses Decision On Closed Source 157

krow writes "I am very happy to be announcing that MySQL will be forgoing close sourcing portions of the MySQL Server. Kaj has the official statement in his blog. No portion of the server will be closed source including backup, encryption, or any storage engines we ship. To quote Kaj 'The encryption and compression backup features will be open source.' This is a change from what was previously posted here on Slashdot. I've posted some additional thoughts on my own blog concerning how we keep open source from becoming crippleware. Word has it that we will also have a panel at this year's OSCON discussing this topic. Contrary to the previous Slashdot discussion, this shows Sun's continued commitment to Open Source."
