necromante asks: "I've been working on different IT positions through my career: support; some networking; DBA; web development; project management; even working on the client side for a little while. However, I don't feel like I am really a specialist on any of those subjects and I feel I need to focus on a particular field. So, I decided to ask for some feedback before making my decision. I understand that this depends everyones tastes, likes and dislikes. However, I would like to have a better idea of which are the available options, and I hope the results of this discussion can benefit other readers. Is there any IT career that I should consider more than the others? Which are the emerging fields? Is there any industry I should focus on in particular? Which careers on IT are actually more in demand and which ones not? Is it a better path to focus on moving into management?"

XxtraLarGe asks: "As both a technician for my college's Distance Learning program and as an avid gamer, I have been tasked with investigating Second Life as a possible way for us to extend and enhance our online classes. I've done a lot of research, reading about what other schools have done. While I personally think it is a really cool idea, I am somewhat skeptical of the actual practicality and value of what seems to be a glorified chat room. I'd like to hear from others about their education experience in Second Life, particularly if you've been involved in setting up any online classes or taken any online classes. What sort of training would be required for the faculty, and is it really worth it?"

intelinsight asks: "Consider the following question given the current software development needs, and also the claims of the Assembly lovers for it being a language that gives one insights of the internal working of a computer. How relevant or useful is it to learn Assembly programming language in the current era? "

Yesterday we discussed possible problems with Microsoft's Xbox Live service, and Take Two's shaky future. The Gamerscore blog reports that worried Live users should know the service has not been compromised. "We want to reassure all of our 6 million Xbox Live members that we have looked into the situation and found no evidence of any compromise of the security of Bungie.net or our LIVE network. There have been a few isolated incidents where malicious users have been attempting to draw personal information from unsuspecting users and use it to gain access to their LIVE account." Meanwhile Chis Morris has it on good authority that, even if Take Two does sell, it won't be to Microsoft. "Because today's independent publishers are platform agnostic - that is to say, they build games for all major systems - taking over one would result in a massive revenue loss for Microsoft, as all development would be redirected toward the Xbox 360."

Sparr0 asks: "Microsoft has announcement that DirectX 10 will not be released for Windows XP (which means no Shader Model 4.0 and no Geometry Shaders). I have since been waiting for news of game developers switching to OpenGL, in order to get the best graphics on the best hardware on the most popular gaming OS, however there is nary a whisper of such. Will such a shift occur, even if only in small amounts? When? Why not? It is probably safe to say that Unreal Tournament 3 (AKA UT2007) will have OpenGL as an option in Windows, but that is both unsurprising and also a long way off. Ditto for Quake Wars, and most other games that are planning a native Linux clients. Where are all of the other big names with Windows-only offerings? Why haven't we heard from Valve, Blizzard, Sony, or EA, to name a few?"

sarahbau writes "Silverbrook's new Memjet technology can print 60 full-color pages per minute. Instead of having a print head that moves side to side like current inkjets, the print head spans the full width of the page, containing 70,400 nozzles in the A4 version. They also have a large-format printer (51") that prints 6" to 1 foot per second. Products are expected to start shipping in late 2007: first a photo/label printer, then a home/office printer for less than $300 in 2008." The video is amazing. If it's for real, the technology would be disruptive at half the speed and twice the price.

holden karau writes "Gigahertz are out and cores are in. Programmers must begin to develop applications that take full advantage of the increasing number of cores present in modern computers. However, multi-threaded development has been notoriously hard to do. Researcher Stefanus Du Toit discusses and demonstrates RapidMind, a software system he co-authored, that takes the pain out of multi-threaded programming in C++. For his demo he created a program on the PlayStation 3 representing thousands of chickens, each independently tracked by a single processing core. The talk itself is interesting but the demo is golden."

pnutjam asks: "I work for a small to medium mental health company as the Network Administrator. While I think a SAN is a bit of overkill for our dozen servers, it was here when I got here. We currently boot 7 servers from our SAN, which houses all of their disks. Several of them have started to show excessive disk load, notably our SQL server, and our old domain controller (which is also the file/print server). I am in the process of separating our file/print server from our domain controller, but right now I get excessive disk load during the morning when people log on (we use roaming profiles). I think the disks need to be defragged, but should this be done on the servers, or on the SAN itself? When it comes to improving performance, I get conflicting answers when I inquire whether I would get better throughput from newer fibre-channel cards (ours are PCI-x, PCI-e is significantly faster), or mixing in some local disks, or using multiple fibre channel cards. Has anyone dealt with a similar situation or has some expertise in this area?"

Fubar asks: "My small company of 10 employees is considering letting our lease run out on our office space and is thinking about having everyone work from home (or wherever they want). I have been tasked with putting a plan together to provide voice and data connectivity to each employee. What sort of solutions have you implemented?"

dclayman wonders: " I've never sold a domain before. I just received a $400 offer for a domain I own (radicaltrust), but I don't know if I should sell it or auction it off. If I auction it, what site should I use? I could really use the extra cash, and I was hoping to get some ideas and advice from other readers. So, what's the best way to go about selling a domain?" Of course, selling your domain is only half of the issue. What's the best way to go about smoothly transferring the domain, once it is sold?

tdelama writes to mention Raytheon Company has developed the first polymorphic computer named the Morphable Networked Micro-Architecture (MONARCH) for the US Department of Defense. "'Typically, a chip is optimally designed either for front-end signal processing or back-end control and data processing,' explained Nick Uros, vice president for the Advanced Concepts and Technology group of Raytheon Space and Airborne Systems. 'The MONARCH micro-architecture is unique in its ability to reconfigure itself to optimize processing on the fly. MONARCH provides exceptional compute capacity and highly flexible data bandwidth capability with beyond state-of-the-art power efficiency, and it's fully programmable.'"

An anonymous reader writes to mention that in the final part of his three part series, Mark Russinovich wraps up his look at changes made in the Windows Vista Kernel by exploring advancements in reliability, recovery, and security. "Applications written for Windows Vista can, with very little effort, gain automatic error recovery capabilities by using the new transactional support in NTFS and the registry with the Kernel Transaction Manager. When an application wants to make a number of related changes, it can either create a Distributed Transaction Coordinator (DTC) transaction and a KTM transaction handle, or create a KTM handle directly and associate the modifications of the files and registry keys with the transaction. If all the changes succeed, the application commits the transaction and the changes are applied, but at any time up to that point the application can roll back the transaction and the changes are then discarded."

Nash writes "Ars Technica takes a look under the hood of Vista, discussing the need for a new API and comparing the graphics engine in Vista to that of Mac OS X. 'With Windows Vista it will be possible to implement Exposé properly-with live window updates and low system overhead. That said, it doesn't thus far look like Microsoft will be doing anything so useful as Exposé. Though the blurred glass effect is rather attractive, it's not exactly useful. Other visual effects include miniature window previews when the mouse cursor is hovered over taskbar buttons and an upgraded alt-tab device, and Flip3D.'"

Here is a giant chart mapping relationships among scientific paradigms, as published in the journal Nature. This map was constructed by sorting roughly 800,000 published papers into 776 different scientific paradigms (shown as pale circular nodes) based on how often the papers were cited together by authors of other papers. Information Esthetics, an organization founded by map co-creator W. Bradford Paley, is giving away 25" x 24" prints of the Map of Science (you pay postage and handling via PayPal). There are also links to a 3000+ pixel wide jpg of the chart. It would be all one long spectrum except for Computer Science, which makes the connection (via AI) between the hard sciences and the soft sciences.
