Per-database and per-collection locking is on the roadmap ..., but it's not here yet. What was announced in MongoDB version 2.0 was locking-with-yield. I was curious about the performance impact of the write lock and the improvement of lock-with-yield, so I decided to do a little benchmark, MongoDB 1.8 versus MongoDB 2.0.'"

First time accepted submitter yuriyg_ua writes "[The] semantic line interface may combine features of both command line and graphical interface, which would allow even more complex applications than we have seen before." The idea is that the layer underlying user interfaces should define the semantic relations between data enabling the UI to provide better contextual information. Kind of a modern version of the CLIM presentation system.

rhartness writes "I am a long time Software Engineer, however, almost all of my work has been developing server-side, intranet applications or applications for the Windows desktop environment. With that said, I have recently come up with an idea for a new website which would require extremely high levels of security (i.e. I need to be sure that my servers are as 100% rock-solid, unhackable as possible.) I am an experienced developer, and I have a general understanding of web security; however, I am clueless of what is requires to create a web server that is as secure as, say, a banking account management system. Can the Slashdot community recommend good websites, books, or any other resources that thoroughly discuss the topic of setting up a small web server or network for hosting a site that is as absolutely secure as possible?"

Only 10,000 tokens to jailbreak Windows Phones were ever granted. According to an announcement through ChevronWP7's Twitter feed, they're discussing whether they will ask Microsoft to make more available. With Lumia falling flat in Europe Microsoft needs all the enthusiastic modding fans they can get."

theodp writes "Google took some heat for pulling the plug on App Inventor for Android, but all was good with the announcement that App Inventor would live on at MIT. But try to run the App Inventor Java test today and you'll be told that 'as of December 31, 2011, Google ended support of App Inventor', even though the Google-funded Center for Mobile Learning at the MIT Media Lab won't be able to provide a large scale App Inventor service for general public access until 'sometime in the first quarter of 2012.' Until then, schools offering App Inventor classes and others who desire continued access to the easy-to-use mobile development environment are advised to try to run their own App Inventor Services on Google App Engine using MIT's test JAR files, a seemingly daunting task, especially considering App Inventor's target audience. Any thoughts on why Google would unplug the old system before the new one was ready?"

Hugh Pickens writes "Some of the people involved in creating WebOS, the HP TouchPad's core software, now say the product never had a fighting chance because it relied on WebKit, an open-source software engine used by browsers to display Web pages, that just didn't have the horsepower to run fast enough to be on par with the iPhone. 'Palm was ahead of its time in trying to build a phone software platform using Web technology, and we just weren't able to execute such an ambitious and breakthrough design,' says Paul Mercer, who oversaw the interface design of WebOS and recruited crucial members of the team. 'Perhaps it never could have been executed because the technology wasn't there yet.' Another problem was the difficulty in finding programmers who had a keen understanding of WebKit as Apple and Google snatched up most of the top talent including Matias Duarte, vice president of human interface and user experience for WebOS, who left for Google a month after HP's acquisition of Palm. 'When he left, the vacuum was just palpable. What you're seeing is frankly a bunch of fourth- and fifth-stringers jumping onto WebOS in the wake of Duarte's leaving.' CEO Meg Whitman has announced that HP will release the WebOS code for anyone to use, similar to Google's open-source strategy with Android, but some say WebKit will still leave WebOS underpowered relative to Apple's software."

First time accepted submitter martypantsROK writes "It's been over 15 years since my main job was a software engineer. Since then I have held positions as a Sales Engineer, then spent a few years actually doing sales as a sales rep (and found I hated it) and then got into teaching. I am still a teacher but I want to really get back into writing code for a living. In the past couple of years I've done a great deal of Javascript, PHP, Ajax, and Java, including some Android apps. So here's the question: How likely would I be to actually get a job writing code? Is continual experience in the field a must, or can a job candidate demonstrate enough current relevance and experience (minus an actual job) with a multi-year hiatus from software development jobs? I'll add, if you haven't already done the math, that I'm over 50 years old."

An anonymous reader writes to point out this interesting outgrowth of Google's Native Client: a Google engineer has ported MAME 0.143 to the browser-based platform, and written about the process in detail, outlining the overall strategy employed as well as specific problems that MAME presented. An impressive postscript from the conclusion: "The port of MAME was relatively challenging; combined with figuring out how to port SDL-based games and load resources in Native Client, the overall effort took us about 4 days to complete."

jones_supa writes "Ville 'viznut' Heikkilä presents us with an interesting project. 'As demonstrated by the video, IBNIZ (Ideally Bare Numeric Impression giZmo) is a virtual machine and a programming language that generates video and audio from very short strings of code. Technically, it is a two-stack machine somewhat similar to Forth, but with the major exception that the stack is cyclical and also used at an output buffer.' The main goal of IBNIZ is to provide a new platform for the demoscene. Something that would have the potential to displace MS-DOS as the primary platform for sub-256-byte productions."

GAMBAS is component-based, so check out the list for an idea of what you can do with it."

wiredmikey writes "In a rare move, Microsoft is breaking its normal procedures and will issue an emergency out-of-band security update on Thursday to address a hash collision attack vulnerability that came into the spotlight yesterday, and affects various Web platforms industry-wide. The vulnerability is not specific to Microsoft technologies and has been discovered to impact PHP 5, Java, .NET, and Google's v8, while PHP 4, Ruby, and Python are somewhat vulnerable. Microsoft plans to release the bulletin on December 29, 2011, at 10:00 AM Pacific Time, and said it would addresses security vulnerabilities in all supported releases of Microsoft Windows. 'The impact of this vulnerability is similar to other Denial of Service attacks that have been released in the past, such as the Slowloris DoS or the HTTP POST DoS,' said security expert Chris Eng. 'Unlike traditional DoS attacks, they could be conducted with very small amounts of bandwidth. This hash table multi-collision bug shares that property.'"

rsmith84 writes "I'm the Senior Systems administrator for a small trade college. When I was hired on, it was strictly for L3 related tasks such as advanced server administration, Exchange design and implementation, etc. They have no in-house programmers, no help desk software, and no budget to purchase one. I'm a moderate PHP and MySQL programmer on the side and am easily capable of writing something to meet their needs, but do not believe I should be A) asked to or B) required to, as my job description and employment terms are not based upon this skill set. I like a challenge, and since all of my goals outlined since my hire date have been met and exceeded, I have a lot of down time. So I wrote the application. It streamlines several critical processes, allows for a central repository of FAQ, and provides end users with access to multiple systems all in one place. I've kept a detailed time log of my work and feel I should be remunerated for the work before just handing over the code. The entire source was developed on personal equipment off company hours. My question is: what should I do? If they are willing to compensate me, I will gladly hand it over. However, it's been mentioned that, if I do the project, it is all but guaranteed that I will see no compensation. The application would streamline a lot of processes and take a lot of the burden off my team, freeing them up to handle what I deem to be more challenging items on their respective punch lists and a better utilization of their time and respective skills. I'm a firm believer in not getting 'something for nothing,' especially when the skills are above my pay grade."

First time accepted submitter nzyank writes "The other day I bravely (foolishly?) volunteered to conduct a video game development workshop at my boys' HS. This in Smallsville, Vermont with an average graduating class size of about 20. The idea is to meet once a week and actually create a game, start to finish. It will be open to would-be programmers, designers, artists, etc. I worked on a bunch of AAA titles back in the '90s, but I'm pretty much out of touch nowadays and I'm trying to figure out the best approach. The requirements are that it has to be one of either Windows/XBox or Android, since those are the platforms that I am current on. It has to be relatively simple for the kids to get up and running quickly, and it needs to be as close to free as possible. Teaching them to use stuff like Blender, C#, C++, Java, XNA, OpenGL and the Android SDK is probably a bit much. I was thinking of something like the Torque Engine, but they want $1000 for an academic license, which is never going to happen. I simply don't know what's out there nowadays and could really use some suggestions."

theodp writes "In the Sixties, we could put a man on the moon. Nowadays, laments jocastette, America's tech giants can't even put a BASIC on the phone. Woz managed to crank out a BASIC interpreter for the 6502 in the '70s. As did Bill Gates and Paul Allen. So, why — at a time when development has never been easier — can't Google, Apple, and Microsoft manage to support a free BASIC or other programming-for-the-masses development environment on desktops, laptops, tablets and phones?" My limited experience with Android development showed using Java to be obtuse and downright obnoxious to do anything (at least without Eclipse, and even with it doing anything non-standard required digging through horrendous ant buildfiles). And, of course, without a REPL things were even more obnoxious. There is the android-scripting project, but it doesn't provide particularly exhaustive access to the platform.

mikejuk writes "It was on this day 220 years ago (December 26 1791) that Charles Babbage was born. The calculating machines he invented in the 19th century, although never fully realized in his lifetime, are rightly seen as the forerunners of modern programmable computers. What if he had succeeded? Babbage already had plans for game arcades, chess playing machines, sound generators and desktop publishing. A Victorian computer revolution was entirely possible."

cultiv8 writes "I am a developer and released some code at one point under GPLv2. It's nothing huge — a small Drupal module that integrates a Drupal e-commerce system (i.e. Ubercart) with multiple Authorize.net accounts — but very useful for non-profits. Earlier today I discovered that a Drupal user was selling the module from their website for $49 and claiming it was their custom-made module. I'm no lawyer, but my perspective is this violates both the spirit and law of GPLv2, most specifically clause 2-b: 'You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.' Am I correct in my understanding of GPLv2? Do I have any recourse, and should I do anything about this? I don't care about money, I just don't want someone selling stuff that I released for free. How do most developers/organizations deal with licensing infringements of this type?"

Meanwhile in NYC, CIOs lament that they are unable to retain 20-something techies according to a report in Network World. Says one CIO, 'It puts us in a really uncomfortable position to have this kind of turnover because knowledge keeps walking out the door. We invest in training people and bringing them up to speed to where they need to be, and boom they're gone. That has been my biggest struggle and concern.' It's the pay, stupid!"
