  1. Re:Hmmm on Wireless LANs Face Huge Scaling Challenges · · Score: 2

    Mod parent up.

    802.11b/g really is overcrowded. It doesn't help that you have to pay a premium on laptops that offer 802.11a/b/g(/n). Additionally, APs cannot offer full 11MB/s for B and 54MB/s for G in all zones. This is, afterall, a radio device, and follows radius-squared laws for intensity of signal. The farther you move away from the AP, the less signal you will receive and slower throughput.

    And then you realize that routing wires in false-ceiling environments actually IS more expensive than setting up AP from ceiling mounts. You essentially reduce the total amount of cables by a factor of 10.

    Ever heard of Cisco's Unified Wireless Architecture?

    Let's remind ourselves here for a moment: large networks are not easy to set up. You run into a number of problems including backend, connectivity, and end user access. The CUWN makes it easier by allowing you to control the AP (Lightweight AP's really - they only work in conjunction with a controller) from a central hook, and you can set the entire scope's settings. It also has guest access features which the article mentions.

    Sometimes Wired networks aren't the most straightforward to get a building network access.

    An additional feature is being able to seamlessly migrate from AP to AP based on radio signal to noise ratios. This allows the network to authenticate the most appropriate AP to the clients based on load.

    Yes, I know a lot about electricity.

    Under the same load, the 750W PSU will draw more power in the conversion process than a smaller PSU. This has nothing to do with load and everything to do with current capacity. Having the capacity for 750 W means there is a larger power transformer in the PSU, and at all time this will draw more current than a smaller transformer. I wouldn't be surprised if the PSU also has more "power" options such as redundancy, each additional branch requiring a separate DC-DC voltage converter, also siphoning off extra power.

    Virtualization these days makes is super easy to run Windows on your Unix install. It makes it safer to do so as well, since you can simply revert to snapshots when something goes wrong.

    I did this with my laptop that had Vista installed. Reboot, reformat, install Ubuntu, VMware; and now I can run XP faster thru VMware than I could running Vista native.

    For being an IT guy, I'm surprised you haven't considered utilizing your hardware to it's maximum performance.

    Reusing my case and pc P&C 750W psu saves me real $

    750W != Saving money.

    You probably would save more if you went to 400 or 500W PSU. What are you running in that box, a microwave oven? The use for anything above 500W that I've seen is to power multiple GPU cards or run liquid cooling. Neither of which sounds like your case.

    That won't really help much either. The scrolls are in Aramiac. I still haven't seen a digital translator that works from Hebrew -> English. Good luck on making any sense from the scans. It sounds a lot like da Vinci's journals. They may be nice to look at, but the Layperson cannot understand them.

    You have no idea what you're talking about. Buelher was put into management because he can lead the teams much better than the rest. You should be blaming the Marketing Department. He actually helped reshape the R&D cycle to become more streamlined and better in-game play.

    MTGO's woes are blamed on a tiny programming team that can't do databases. They have 5 people working on the program. Tops.

    Gleemax is just another example of the same marketing demon running the company. There is little need to appease the current ranks of players because they are hooked. Instead they focus their direction at new players with geeky gimmicks such as this piece of dreck.

    Why are you still thinking about thinks in Volts?

    Semiconductors, motors, and radios are based on currents. (CMOS not so much, but hear me out) Lets change the way energy is transmitted to current sources and suddenly it makes things much easier to operate. Also makes all those LED lighting so much easier to place everywhere, further improving efficiency of lighting devices.

    That would be nice to have a universal charger; however not every device has the same battery. Ever try to charge your cell phone with a car battery recharger? Instant meltdown. There is a reason each device has it's own family of chargers - they need a rated current at a rated voltage.

    Then you probably wouldn't like the larger sum of money being sent to the Palestinian gov't for aid.

    For instance roughly $3,000,000,000 given to the PLO [aka Yassar Arafat] in 1993 by the USA and international donors after the Oslo accords. Money that never saw its way to the Palestinian refugees in entirity. Most estimates put the GDP of Palestinians at roughly $1,300, while PLO generated between $8,000,000,000 and $14,000,000,000 from a 5% tax generated from Palestinians working in Arab countries (circa 1990).

    British intelligence also estimates that Yassar Arafat controlled assets worth over $10,000,000,000 and the PA has a $2,000,000,000 operating budget. Keep in mind that the population of Palestinian refugees living in the disputed territories is around 4,000,000 people.

    Additionally, Israel economic aid totals $0 as of this year.

    You can play the blaming game, but you better think about the aid being sent to the Palestinian Authority as well. This isn't a one way street pal. Ask yourself where the money comes from to "aid" the corrupt PA gov't and why the money isn't helping the refugees.

  16. Re:A disappointing digital offering from Hasbro? on Scrabulous Is Dead, Hasbro's Version Brain-Dead · · Score: 2, Interesting

    The problem I saw with Hasbro/EA Scrabble on Facebook was more of a problem with EA's "add more features that don't add basic functionality" like they butcher every game they touch.

    Hasbro's other departments, and specifically Wizards of the Coast which owns the brands for D&D and MTG, have failed to bring a good product to market for the same reasons. Instead of focusing on the basics, they bloat with features that only make the software look and play nice, but cannot mimic the underlying mechanics. Even before Magic Suitcase, there was Apprentice. This was free, widely used, no thrills attached program maintained by fans on their own time so that players online could enjoy the game. It was not based on ad revenue, it was less than 2MB and included TCP socketing. So what did WotC do? Send a Cease & Desist notice to the developers claiming copyright infringement. Two years later they released a product with lots of thrills, over 100 times the size, and a click-intensive program.

  19. Yes, on Does It Suck To Be An Engineering Student? · · Score: 1

    it does suck to be an engineering student. Even more so when our entire department (EE) is going through re-accreditation and all the academic planning goes to shit because of unavailable courses. Here's my response to the Top (Bottom) 5.

    1. Books.
    My quarterly book costs are in the $300-400 range for 3-4 books total. In comparison to soft majors: $50 for 10+ paperbacks. Expensive? CHECK. Useful? CHECK. I personally don't know any LA/Biz students who keep their books after the term is done. That has something to do with the fact that most of the courses taken by non-engineering/sciences don't build on top of previous courses. In one such series, Microelectronics, we not only build on the circuit analysis and semiconductor device courses, but also on programming (simulation tools), physics, and easily calculus. These books we purchase build our reference library for when it really matters to have them.

    2. Professors / Padded grades
    Can't do much here, there's some good professors who are prepared and know how to teach. There are also awful professors (and sometimes even good lecturers) who grade tough as nails, even with a curve. This is not a symptom of the professor, but of the college. When over 40% of the grade is depending on a single exam, there's lots of room for error. The grading curve alludes to this, and interestingly enough at my university the curve dips lower the higher up you go.
