In this recent Slashdot post kernel hacker Harald Welte was characterized as "VIA's open source representative," but that is just one of many irons he has in the fire, as a glance at his Wikipedia bio will show. You can obviously ask Harald about many interesting things besides VIA's open source strategy — and before you ask about VIA, you ought to read the last few entries on his blog, at least one of which mentions VIA questions he can't answer. But VIA aside, there's plenty to ask Harald about. For example, he won an award from the FSF earlier this year for his work on gpl-violations.org. In any case, Harald is a powerful force for GNU/Linux and Free Software, and we appreciate him taking time out of his undoubtedly hectic schedule to answer your questions. (Usual Slashdot interview rules apply.)

Recently I switched to using Ubuntu in VMware player, it is much faster and it also introduces me to a 'real' reason to play with Linux (been looking for a 'real' reason for ages). Are there any specific distributions which allow you to have a virtual webserver on your desktop? Any tips and tricks out there for this?"

I'm a web developer who has design and programming experience. So, VB, ASP, PHP, Coldfusion, Perl, even C and C++ I have in my belt. I also use Dreamweaver and/or do a lot of my HTML/XHTML/JavaScript coding by hand. So, the DOM, DHTML, etc, all good to me and even OOP thinking and design I have when I code. And I even have MySQL and other databases, again, not an issue here. So, my weak point is — Java — I see so many jobs out there with J2EE, Hibernate, Eclipse, Netbeans. Beside the obvious, which is to learn Java the core language, I don't know where else to go from there. There is so much! What should I read? in what order? What software do I require? UML? Swing? I mean, what is the curriculum required for someone to say they are a solid Java developer? Even assuming I have to go through Java itself, what are the good books out there?

An anonymous reader writes "I am a American citizen with a masters in Computer Science from a 3rd tier college and 4 years of work experience under my belt. I would like to work somewhere abroad in Europe for a couple years before I get too settled in life but have no clue where to start. I only speak English but would love to learn a second language. What sort of opportunities are there for American citizens to work abroad? What countries offer the best opportunity to balance a challenging work environment with enough vacation to explore the rest of Europe in my free time? Any hassles I should know about?"

Mike writes with a timely link to a story about the ESPN/TopCoder Winning Formula Challenge, a combination of fantasy football and competitive programming. The goal is to write an algorithm to predict the outcome of college football games using a collection of historical data provided by the tournament organizers. The season is broken up into 3-4 week chunks that are used to evaluate the results. Prizes will total $100,000.

An anonymous reader writes "A group of Canadian engineering students was one of 10 teams to win a $275,000 prize from internet search giant Google Inc. Their program, Ecorio, gives users the ability to reduce their environmental footprint with tools that provide transit options for trips, invest in carbon reduction projects, and share their tips with other users. Other winners included a taxi location app, a price comparison app, and a settings manager than changes your settings based on your location." Google has also started talking about their plans for Android Market, which is similar to the App store used for the iPhone. Ars Technica's coverage points out a blog post by Google's Eric Chu which notes that early handsets running Android will have a beta version of Android Market enabled.

ruphus13 writes "A lot of developers for open source software have full-time day jobs too. As economist Milton Friedman said, 'The business of business is business.' So, does it make sense for companies to encourage their developers to contribute to the open source community? OStatic discusses a blog post by Alfresco exec Matt Asay, who makes the case for why they should. '"Companies like IBM, Intel, SGI, MIPS, Freescale, HP, etc. are all working to ensure that Linux runs well on their hardware. That, in turn, makes their offerings more attractive to Linux users, resulting in increased sales." While I don't think we'll ever see companies everywhere subsidizing employee development of open source tools, many tech and non-tech companies alike could benefit from subsidizing open source development from employees with talent. If more companies woke up to this idea, we'd see more purpose-driven, mission-critical open source software shared by firms in the same industries. That, ultimately, would benefit the companies providing the subsidies.' Should your employer pay you for time spent on open source development?" snydeq points out an Infoworld story suggesting that there's something to learn from the way French companies are promoting open-source development.

Esther Schindler writes to tell us that Lynn Greiner has another look at the state of the scripting universe as a follow on to the same topic three years ago. Greiner talks to major players from each of the main scripting languages (PHP, Perl, Tcl, Python, Ruby, and Javascript) to find out the current status and where they are headed in the future. "The biggest change since 2005 has been the growth of richer Web applications that perform more of their computations in the browser using JavaScript. The demand for these applications has forced developers to learn and use JavaScript much more than before. There's also been a lot of interest in Ruby, another dynamic language, spurred by the release and growth of Ruby on Rails. As a result of these changes, many developers are becoming more comfortable with dynamic languages."

snydeq writes "Smart coders always optimize the slowest thing. But what if 'the slowest thing' is the code supplied by your vendor? That was exactly the situation Vipul Ved Prakash discovered when he tinkered with a company Linux box on which Perl code was running at least 100 times slower than expected. The code, he found, was running on CentOS Linux, using Perl packages built by Red Hat. So Prakash got rid of the Perl executable that came with CentOS, compiled a new one from stock, and the bug disappeared. 'What's more disturbing,' McAllister writes, 'is that this Red Hat Perl performance issue is a known bug,' first documented in 2006 on Red Hat's own Bugzilla database. Folks affected by the current bug have two options: sit tight, or compile the Perl interpreter from source — effectively waiving your support contract. If a Linux vendor can't provide comprehensive maintenance and support for the open source software projects you depend on, McAllister asks, who ever will?"

linnrose writes "When I purchased my current cell phone — a ATT/Samsung Sync — my primary reason for selecting it was Samsung told me I could install custom Java applications on it via USB or the microSD card; turns out they lied to me. I would really like to have a phone that is open enough for me to install simple Java (or whatever language; I'm primarily a C# developer) apps without having to download them from a server. And it doesn't have to be cutting-edge/feature-rich; gimme a nice color screen and good call quality. I'm thinking Nokia might have something useful, but I'm not sure. Any suggestions?"

Julie188 writes "A Microsoft SQL Server 2005 fan toppled over in surprise when he got this error message from SQL Server 2008 (he was running the SQL Server 2008 Upgrade Advisor tool): 'In SQL Server 2008, SQL Server native SOAP has been deprecated and will be removed in a future SQL Server release ... Avoid use of SQL server native SOAP in new development work, and plan to modify applications that currently use it.' No more SOAP-based Web services for your SQL Server database? Native XML was only added in v.2005 and was much ballyhooed at that time."

CurtMonash writes "MapReduce sits at the heart of Google's data processing — and Yahoo's, Facebook's and LinkedIn's as well. But it's been highly controversial, due to an apparent conflict with standard data warehousing common sense. Now two data warehouse DBMS vendors, Greenplum and Aster Data, have announced the integration of MapReduce into their SQL database managers. I think MapReduce could give a major boost to high-end analytics, specifically to applications in three areas: 1) Text tokenization, indexing, and search; 2) Creation of other kinds of data structures (e.g., graphs); and 3) Data mining and machine learning. (Data transformation may belong on that list as well.) All these areas could yield better results if there were better performance, and MapReduce offers the possibility of major processing speed-ups."

Gamasutra is running a story deconstructing the mechanics of Portal's teleportation programming. They present a snippet of Portal's code and a downloadable demo. They ran another article in this series earlier this year with an analysis Mario Galaxy's unique take on physics. We've discussed the development of Portal in the past. "Teleport mechanics in video games are nothing new. Puzzles from the original Gauntlet were memorable -- and more than likely, that wasn't the first game to use teleportation as a gameplay mechanic. The difference between Portal and all those that came before it is that Portal's teleportation acts as a frictionless tube between point A and point B. Physics are still hard at work inside the frictionless tube. Instead of simply repositioning an object from point A to point B, the player enters point A with full velocity and exits point B with the same speed, but moving in a new direction." Update: 8/26 at 19:37 by SS: Dan notes that the code was not directly from Portal; it was written to approximate Portal's physics.

I Don't Believe in Imaginary Property writes "The database used by the government to generate lists like the No-Fly List is 'crippled by technical flaws,' according to the chairman of a House technology oversight subcommittee. And the upgrade may be worse than the original. Rep. Brad Miller (D-NC) says that 'if actually deployed, [the upgrade] will leave our country more vulnerable than the existing yet flawed system in operation today.' It seems that the current database doesn't have any easy way to do plain-text matching, forcing users to enter SQL queries. That might not sound so bad until you learn that the database contains 463 poorly indexed tables. How long until there's a terrorist named Robert'); DROP DATABASE; —?"

Nicros writes "I work for a publicly traded biotech company that happens to write software that is, in fact, kind of critical for the business — without it no data would ever be read from our instruments, and no analyses would be performed on that data. The problem is that as a 'biotech' company, we are not taking software quality seriously. We have no senior management with any history of commercial software development — our C level has really no clue whatsoever what software really is, much less what is going on in software development. All of our quality processes are related to manufacturing our system (not software), so we are constantly forced into ad-hoc development since there is no real process for our development. Repeated requests to hire someone with some real commercial software development experience have gone unanswered. I have been to the CEO directly one-on-one and although he agreed this was an issue, thanked me, and said he would look into it, that was the end of it. He has bigger things to worry about. So the question: Is this just a fact of life and I need to deal the best I can? What else can I do to get some attention on software quality in the company?"

CurtMonash writes "I had been a database industry analyst for a decade before I found 1-gigabyte databases to write about. Now it is 15 years later, and the 1-petabyte barrier is crumbling. Specifically, we are about to see data warehouses — running on commercial database management systems — that contain over 1 petabyte of actual user data. For example, Greenplum is slated to have two of them within 60 days. Given how close it was a year ago, Teradata may have crossed the 1-petabyte mark by now too. And by the way, Yahoo already has a petabyte+ database running on a home-grown system. Meanwhile, the 100-terabyte mark is almost old hat. Besides the vendors already mentioned above, others with 100+ terabyte databases deployed include Netezza, DATAllegro, Dataupia, and even SAS."

monkeymonkey writes "Mozilla has integrated tracing optimization into SpiderMonkey, the JavaScript interpreter in Firefox. This improvement has boosted JavaScript performance by a factor of 20 to 40 in certain contexts. Ars Technica interviewed Mozilla CTO Brendan Eich (the original creator of JavaScript) and Mozilla's vice president of engineering, Mike Shaver. They say that tracing optimization will 'take JavaScript performance into the next tier' and 'get people thinking about JavaScript as a more general-purpose language.' The eventual goal is to make JavaScript run as fast as C code. Ars reports: 'Mozilla is leveraging an impressive new optimization technique to bring a big performance boost to the Firefox JavaScript engine. ...They aim to improve execution speed so that it is comparable to that of native code. This will redefine the boundaries of client-side performance and enable the development of a whole new generation of more computationally-intensive web applications.' Mozilla has also published a video that demonstrates the performance difference." An anonymous reader contributes links the blogs of Eich and Shaver, where they have some further benchmarks.

An anonymous reader writes "DevX interviewed Bjarne Stroustrup about C++0x, the new C++ standard that is due in 2009. Bjarne Stroustrup has classified the new features into three categories: Concurrency, Libraries and Language. The changes introduced in Concurrency makes C++ more standardized and easy to use on multi-core processors. It is good to see that some of the commonly used libraries are becoming standard (eg: unordered_maps and regex)."

snydeq writes "Fatal Exception's Neil McAllister questions the wisdom of standardizing on a single language in the wake of the ECMA Committee's decision to abandon ECMAScript 4 in favor of the much less ambitious ECMAScript 3.1, stunting the future of JavaScript. Had the work continued, McAllister argues, it could have ushered in an era of large-scale application development that would ensure the browser's ability to meet our evolving needs in the years ahead. 'The more I hear about the ongoing efforts to revise the leading Web standards, the less convinced I am that we're approaching Web-based applications the right way,' McAllister writes. 'If anything, the more we talk about building large-scale Web applications, the more we should recognize that a single style of programming will never suit every job.' McAllister's simple truth: JavaScript will never be good for everything — especially as the Web continues to evolve beyond its original vision. His solution? 'Rather than shoehorning more and more functionality into the browser itself, maybe it's time we separated the UI from the underlying client-side logic. Let the browser handle the View. Let the Controller exist somewhere else, independent of the presentation layer.'"
