  1. How is the FP "Redundant"? on Hole in Asteroid Belt Reveals Extinction Asteroid · · Score: 1

    At the risk of being modded down to oblivion, how is the First Post considered "Redundant"?!?!? (First post -- Redundant -- where's the logic in that? ...I digress..)

    Actually, if I had any mod points, I'd mark him "Insightful".

    How many "redundant" articles do there need to be on /. about junk science until people get it? *Most* of the "science" articles you read are sensationalized junk and are all about maximizing grant money.

    Do people believe everything they read or do they still have an analytical brain? (Obviously, somebody with mod points doesn't).

    I agree with the "Redundant" FP:
      This article was written on the basis of a suggestion? Please get back to me when you have facts.

    Junk that is a mere "suggestion" is obviously not fact-based. As a matter of "fact," I shall not read this article on principle.

    Solar, small-scale wind, or algae would all be viable on a large percentage of building rooftops, if people start thinking small-scale and cheap.

    There is *no* magic silver bullet. However, if large numbers of people chip away small pieces at a time (local production and reduction in consumption), we could end any energy crisis and at least produce a large percentage of what we consume.

  8. Telephone Masts vs. WiFi... on How Bad Can Wi-fi Be? · · Score: 2, Interesting

    If you're talking about cell towers, the maximum radiated wattage is a mere 16 Watts. For most "normal" WiFi, the max is about 100mW, or 0.1W. In reality, it may be a mere 28mW or 0.028W (Linksys, for example).

    So, on one hand, 16W (cell) vs 0.028W (WiFi) is quite the difference.

    However, the distance falls off in a square inverse fashion. If you're 1M away, you get 100 times the power as if you're 10M away, so as for how much power you get, it's all relative to distance.

    If you are 1M from your Linksys and 10Km from a cell tower, I'd bet the cell tower "loses" (lay of land, atmosphere, and walls in home may change things, of course). If you're on the other side of concrete from your Linksys, in that scenario, the cell tower may "win".

    If your Linksys or cell tower were VHF, instead of the high-frequency UHF that they both are, skin "absorption" might be quite different.

  9. Re:Stop the press on Performance Evaluation of Xen Vs. OpenVZ · · Score: 1

    As somebody that has used OpenVZ, VMware (several flavors, since the early beta days), QEMU, Bochs, Linux-VServer, and others, I like OpenVZ (and VMware Server but for totally different reasons). I looked at Xen and decided that I would grow old setting it up, so I abandoned that effort, for now.

    OpenVZ is easy to setup (once you get the kernel and packages setup, which is a breeze in Debian 3.1 and 4.0). It runs ridiculously fast, it consumes little memory, and takes little disk space (which can be further enhanced using hard links). Besides that, everything is fully scriptable. I also only have to maintain a single kernel (on the host).

    By reducing isolation (jails/containers vs. virtualization), the host machine can directly copy files into and out of guests, but the guests can't directly see each other (you can through ssh, for instance).

    I also like the fact that on the host machine, using ps -ef (or ps aux) gives you information on ALL processes, whether host or guest. The tty column shows you which machine owns a process.

    Since it's a shared kernel and uses shared memory, resource utilization is superior. If a guest isn't doing anything, it really isn't doing anything at all, unlike the virtualizers (except the up-and-coming KVM). The virtualized machines, for instance, keep running the "do nothing loop" when the OS is idle. (I believe that VMware Tools is supposed to help a bit in this regard). And, if processes aren't running or disk space isn't being used, then, unlike VMware, resources aren't being consumed.

    This is basically a way to run multiple guest Linuxes under a host, not a full virtualization environment, so there are trade-offs. I think that for running multiple Linux servers (as opposed to desktop apps), OpenVZ/Virtuozzo is an ideal solution.

    Since I'm running a smallish server at home, I've found that OpenVZ is the best way to run so many Linux guests at once.

    I will have to say that I have not tried UML because of performance. I can't try KVM since I don't have the correct AMD processors.

    I was also initially impressed by Linux-VServer but got stuck, somewhere, but I cannot remember where. I found that OpenVZ seemed to be easier and more powerful than Linux-VServer, its virtualization cousin.

    Here's a decent comparison of the kinds of VM's available for Linux:

  13. Would you trust these professionals? on Is Assembly Programming Still Relevant, Today? · · Score: 5, Insightful

    The original post asks if Assembly is still relevant today. I'll ask some rhetorical questions (the only kind in a blog) and see how they apply:

    * Would you want an astronaut to understand physics and math?
    * Would you want a doctor to understand chemistry and biology?
    * Should somebody studying to be a Literature teacher take their full set of liberal arts courses, including history?
    * Should somebody earning a business degree take music appreciation?

    Most of us probably said, "Yes" to most or all of those above. Even if the study seems irrelevant or too "low-level" or too "high-level" at the time, there are areas of coursework that help us understand things better.

    I see a lot of dead wood in the IT industry. There are enormous numbers of people who either have no passion or who do not have a deep-enough or broad-enough knowledge of computer science to do their daily data processing job well. They are dependent on others around them for everything, even though they may be very skilled in one area.

    By having both a broader and a deeper knowledge, people are necessarily better at troubleshooting and at understanding the areas outside their particular specialty. It makes them be better at all of IT and helps them do their specific role.

    You should learn IT two ways -- deeply and broadly. You should deeply learn specific skills (Java/C#/Linux/Windows/scripting in Ruby/whatever) and you should learn broad skills (computing theory/relational databases/networking/troubleshooting/programming/a nalysis/architecture/whatever). The difference is training vs. education.

    There is an enormous difference between training and education. Training is learning specific skills for specific tasks (narrow/specific), while education is broader and teaches you how to think, understand, and apply (broad/general).

    While taking Assembly may not seem relevant at the time and you may never directly use it again, for every programming task, having a strong background in all of computing theory (including how the CPU handles its low-level instructions) educates you and gives you a deeper understanding. (Don't just be trained, be educated!)

    My recommendation is the book My Job Went to India (And All I Got was this Lousy Book). If you can't afford it, read the sample chapters, especially the "Being a Generalist" and "Being a specialist" chapters at http://www.pragmaticprogrammer.com/titles/mjwti/in dex.html.

    Personally, unless you need the specific class/training, I'd say that FORTRAN or COBOL ought to be abolished as required material in all colleges and shouldn't be in the degree program. Those should be electives only. Assembly, on the other hand, should remain required, for a deeper and broader education. (Don't settle for a dumbed-down program).

    The difference, again, is training (specific/skill-oriented/task-oriented) vs. education (general/broad/understanding-oriented). Education and being a generalist will reap large rewards, long term. So stick with it and take that class. Assembly is a very important foundation class that educates you, long-term....

    Another rhetorical question I have is this: "Are you passionate for IT or is it just a high-paying (presumably) job?" If it isn't a passion of yours, find you passion and do it well. If it is, take Assembly and like it -- it'll help you appreciate IT, your computer, your high-level language, and give you a more educated view of the "soul" of your computer.

    (They don't make you take Assembly at many/most schools for their health. It would be a crying shame to remove it from the required courses).

  14. A modest proposal.... on Solar Cell Achieves 40% Efficiency · · Score: 1

    I've seen a large number of ideas for something like this and a list of advantages/disadvantages for each, but here's my two cents....

    First, use rooftops, where possible. This should include new construction as well as old. There could be three options - owner stores extra power in batteries, owner sells back to the grid, or have a power-company-subsidized grid program. For the third option, the power company can make it up by not having to buy as much power over the grid, by selling excess solar electric power, by not having to construct as many new power plants, by not having to upgrade the grid as often, by having less in the way of power losses, and by not having to buy as much fuel to generate power in the first place. (Power-company-subsidized solar power could also get government incentives, I'm sure)....

    Second, someone pointed out that rooftop solar would shadow the roof and reduce AC costs. Yes it would, but I'd add something. The waste heat from the sun could be used for passive solar, as well.... You could run a hot water heater or augment your heat/heat pump in the winter time. Otherwise, in the summer, there would be big savings and in the winter, there might be an actual loss, once you strip away roof heat. By cooling solar panels, the efficiency is actually raised, anyway, IIRC.

    Last, there is no silver bullet. We need to commit to getting off of imported fuels and fossil fuels, in general. We should combine wind, solar, geothermal, nuclear, hydroelectric, biomass, etc. We should never put our eggs in one basket. Plug-in hybrids that use flex fuels give us at least three ways to power a vehicle for daily commutes and reduce our dependence on one resource. Depending on one resource, including solar energy, can be disasterous. Augmenting the current system with the proposed reduces our dependence, in fact.

    If we use a single chunk of land, we don't reduce our dependence on one source for power.... Having large arrays is nice, so long as they're spread out all over the country/world. Rooftop solar should be part of energy independence, as well. It has the added advantage of making power local.

    I also wonder why wind farms don't do solar on the ground, in between windmills....

    I agree with you, that it is an unknown. The field is too new to make a determination. The field simply isn't old enough to have programmers retiring in droves. Yes, where I work, there are 60+ year olds doing COBOL/mainframe stuff, but it's pretty rare in this field.

It was a hard time for programmers, everywhere.

    So, I'll add one theory -- it depends on the job cycle. Compare the dot-com/Y2K/Euro-conversion days with the recessions before and after those days, for instance....
