Comment I love Python, but... (Score 1) 214

If you're teaching them programming, and they might not all use it, maybe you should think about using MS Excel. It seems everyone uses Excel in some form, but the people who can really get into the nitty-gritty of it can do some really useful stuff. Excel is on just about every computer these days, or some similar spreadsheet, and while it's not a traditional programming language, it does require the use of logic to figure out how to set up a series of cells with different commands to give you the answer you want.

Python on the other hand, is much more traditional, and might be a bit more straightforward to teach, but I still think more students would find useful skills they can use everyday in Excel rather than in Python. If they were all going towards engineering or comp-sci, Python would be good, but for the future business people in your class, knowing how to use Excel, and use it very efficiently is a huge plus in the "real world".

Hope For Multi-Language Programming? 371

chthonicdaemon writes "I have been using Linux as my primary environment for more than ten years. In this time, I have absorbed all the lore surrounding the Unix Way — small programs doing one thing well, communicating via text and all that. I have found the command line a productive environment for doing many of the things I often do, and I find myself writing lots of small scripts that do one thing, then piping them together to do other things. While I was spending the time learning grep, sed, awk, python and many other more esoteric languages, the world moved on to application-based programming, where the paradigm seems to be to add features to one program written in one language. I have traditionally associated this with Windows or MacOS, but it is happening with Linux as well. Environments have little or no support for multi-language projects — you choose a language, open a project and get it done. Recent trends in more targeted build environments like cmake or ant are understandably focusing on automatic dependency generation and cross-platform support, unfortunately making it more difficult to grow a custom build process for a multi-language project organically. All this is a bit painful for me, as I know how much is gained by using a targeted language for a particular problem. Now the question: Should I suck it up and learn to do all my programming in C++/Java/(insert other well-supported, popular language here) and unlearn ten years of philosophy, or is there hope for the multi-language development process?"

Microsoft and Red Hat Team Up On Virtualization 168

mjasay writes "For years Microsoft has insisted that open-source vendors acknowledge its patent portfolio as a precursor to interoperability discussions. Today, Microsoft shed that charade and announced an interoperability alliance with Red Hat for virtualization. The nuts-and-bolts of the agreement are somewhat pedantic, providing for Red Hat to validate Windows Server guests to be supported on Red Hat Enterprise virtualization technologies, and other technical support details. But the real crux of the agreement is what isn't there: patents. Red Hat has long held that open standards and open APIs are the key to interoperability, even as Microsoft insisted patents play a critical role in working together, and got Novell to buy in. Today, Red Hat's vision seems to have won out with an interoperability deal heavy on technical integration and light on lawyers."

Comment It's not a bad idea. (Score 1) 585

I have an EZPass (the east coast automated tag thing on my car). I go to school in Washington, DC, and I live in South Jersey. When I drive, I don't notice the total cost of the tolls, and I think it's because of tag. I asked a friend to pick me up at a train station near the end of the MARC (Maryland's train system) line, and I ended up costing him $13 that he paid out of his wallet, and that's just on the way back from the train. I paid him back, but I didn't realize how many tolls there are on I95.

As far as the idea of turning roads into toll systems, I'd prefer the tags. They're a bit more anonymous than a license plate, which could easily be traced by DMV records. I know many people who own one or two tags and just put it in whatever car they're taking for a long trip. My big worry is the day that the politicians realize you can use these things to track how fast people are driving by comparing the time into the system to the time out with the distance driven. I did read an interesting article the other day about an economist proposing we solve our traffic congestion and road funding problems by implementing a dynamic tolls system on all the major highways. A busy road would have a higher toll than a less crowded road, encouraging people to take the cheaper route, and at the same time, providing funds for the highway system. Usually in my travels between DC and home, or between home and my friends in Delaware, I take either 295, a bit longer of a drive, but less crowded, or the New Jersey Turnpike, which has an exit that is a few miles closer to home, which is more direct but seems to be more crowded when I drive it. With some well placed electronic signs, I could tell which route will have more traffic, and the state would make money on both routes, not just the turnpike.

But if you're not in a position to know how much your university spends on software and be able to compare it to how much revenue the university has, you're not in a position to really make a change to open source. Second, thinking of my dealings with fellow university students (I'm an OSS using university student as well), I know many of them would rather use the MS/proprietary version that just works than deal with often buggy open source software that's not always compatible or has bugs left and right. Your university has to deal with the outside world, which is still deeply entrenched in MS Office, unless you're going to show all your students how to export from Open Office to an MS Office format, expect a lot of complaints. Granted, Open Office isn't as buggy as some things, but if you have engineering students who need a good CAD program, don't count on finding a good open source program for them. I wish you luck, but you're really fighting the tide here.

Miscalculation Invalidates LHC Safety Assurances 684

KentuckyFC writes "In a truly frightening study, physicists at the University of Oxford have identified a massive miscalculation that makes the LHC safety assurances more or less invalid (abstract). The focus of their work is not the safety of particle accelerators per se but the chances of any particular scientific argument being wrong. 'If the probability estimate given by an argument is dwarfed by the chance that the argument itself is flawed, then the estimate is suspect,' say the team. That has serious implications for the LHC, which some people worry could generate black holes that will swallow the planet. Nobody at CERN has put a figure on the chances of the LHC destroying the planet. One study simply said: 'there is no risk of any significance whatsoever from such black holes.' The danger is that this thinking could be entirely flawed, but what are the chances of this? The Oxford team say that roughly one in a thousand scientific papers have to be withdrawn because of errors but generously suppose that in particle physics, the rate is one in 10,000."

The Unmanned Air Force 352

coondoggie writes "How important have unmanned aircraft become to the US military? Well how's this: the Air Force says next year it will acquire more unmanned aircraft than manned. Air Force Lt. Gen. Norman Seip this week said the service is 'all in' when it comes to developing unmanned systems and aircraft. 'Next year, the Air Force will procure more unmanned aircraft than manned aircraft,' the general said. 'I think that makes a very pointed statement about our commitment to the future of [unmanned aircraft] and what it brings to the fight in meeting the requirements of combatant commanders.'"

Comment It's great for interns... (Score 1) 1055

I worked it once as an intern. 9 hour days, 8 hours the first friday, off on the next. It was nice because it gave me a chance to take every other weekend off to go do things with friends, like roadtrips, either back home or to the beach. What I didn't like was that I had an hour and a half commute each way, so the 9 hours, plus commute time made for a really long day. Up at 6, and not usually back until 6 or 7, depending on the traffic through DC. As an intern I was never asked to come in on that day, and the job wasn't one where I had urgent deadlines to meet. In the future, I'm not sure if I would do it. It'd really depend on having a shorter commute and knowing that I had something to do on that Friday.

Most Popular Free, Arena-Style FPS? 205

anomalous cohort writes "I am a casual gamer. Go or Chess are my games of choice when I am up for a serious intellectual gaming challenge. Otherwise, I just want to blow off some steam in a free, arena-style FPS such as Alien Arena, Nexuiz, Sauerbraten, or Tremulous at the end of a long day. Either way, it is very rare for my gaming experience to exceed 30 minutes. The problem is that attendance for these games has dropped off over the years. Finding a game with about two humans and two robots is perfect for me and very rare these days. My question is this: What is currently the most popular free, arena-style FPS for the casual gamer that you know of?" That reminds me, how is the Quake Live beta coming along?

State Dept E-mail Crash After "Reply-All" Storm 384

twistah writes "It seems that a recent 'reply-all storm' at the State Department caused the entire e-mail infrastructure to crash. A notice sent to all State Department employees warned of disciplinary actions which will be taken if users 'reply-all' to lists with a large amount of users. Apparently, the problem was compounded by not only angry replies asking to be taken off the errant list, but by the e-mail recall function, which generated further e-mail traffic. One has to wonder if capacity planning was performed correctly — should an e-mail system be able to handle this type of traffic, or is it an unreasonable task for even the best system?"

Actually, at their museum extension out in Dulles, Va, about an hour from downtown DC, they already have the Enterprise. I'd expect if they were to buy a new one, the Enterprise might go somewhere else, or they'll put it at an affiliated museum. And since NASM is probably one of the best funded air and space museum in the country, they might consider picking one up. Who knows, it might end up out in Kansas.

Canadian Nuke Bunker To Be Converted Into Data Fortress 197

miller60 writes "A hosting firm has purchased a nuke-resistant bunker in Novia Scotia, and plans to convert it into a data fortress for financial firms. Bastionhost hopes to attract European financial firms wary of housing sensitive data in the US due to the USA Patriot Act. The facility is one of a series of 'Diefenbunkers' built during the tenure of Prime Minister John Diefenbaker to keep the Canadian government running in the event of a nuclear attack. While not all of these underground data bunker projects work out, a similar nuke-proof bunker in Stockholm, Sweden was recently converted into a stylish high-tech data lair for an ISP."
