  1. They Are Indeed Pointers on 1Gbps Wireless Network Made With Red and Green Laser Pointers · · Score: 1

    I went to the paper, expecting to find a fairly high powered laser that is not a pointer, and expecting to call someone out on calling them pointers. However, they're only 5 mW, which is indeed a pointer. Cool that they can use such low powered lasers for this.

    The FDA has regulations in the U.S. saying that no laser products over 5 mW may be marketed as "pointers":

    Class IIIb lasers cannot legally be promoted as laser pointers or demonstration laser products.

  2. kb != KiB on Demoscene: 64k Intros At Revision Demoparty · · Score: 1

    The summary says 64kb (kilobits), or 64,000 bits. That's 7.8125 KiB (kibibytes), or 8,000 bytes. The competition is actually for 65,536 bytes, or 64 KiB.

  3. Re:Unknown lamer: please re-read article on BOSS: The Universe's Most Precise Measurement · · Score: 2

    It says the universe is precisely 13.75 billion years old, not 13.5 billion years old.

    Actually, you're both wrong. What you read is a link to a different, unrelated article that's 2 years and 2 months old. I looked at the articles and papers, and I don't think any claim about the age of the universe is ever made.

    I think this is instead the most accurate measurement of the distance between here and very far away galaxies, and of the distances between those galaxies. But I may be wrong on that. RTFA

    The defacing of Chinese government's websites were hacks. This is just a DDoS.

  5. Pornographic? on Teacher Suspended For Reading Ender's Game To Students · · Score: 1

    I'm about 75% of the way through my first read of this book. So far I've seen nothing that under any insanely loose definition could be considered pornographic. Now I'm wondering if something happens in the last quarter. I'm going to not RTFA or the comments, and finish the book.

  6. DST Graph on Did Benjamin Franklin Invent Daylight Saving Time? · · Score: 4, Interesting

    If you want a visual explanation of the purpose and result of daylight saving time, check out this graph: Picasa Web Albums - Paul Nickerson

    The purpose, as I understand it, is to make the sun not rise super early against the clock during the summer. The effect is that it reduces the range of sunrise times, while increasing the range of sunset times. In a way, it normalizes sunrises while amplifying sunsets.

    Oh, and while we're at it, during a non-DST period, if the time zones were evenly split and straight with no regard to human geographic borders, then at the middle of the time zone, 12:00 (noon) would be the time that astronomical noon is (when the sun is highest in the sky), varying by about 20 minutes before and after noon. If you average all the astronomical noons over the course of a year in the middle of a time zone, then astronomical noon is at precisely 12:00. During DST, astronomical noon is moved to 1:00 pm (13:00)

  7. Re:Why the "but"? on HDD Price Update: How the Thai Floods Have Affected Prices, 3 Months Later · · Score: 1

    Sounds to me like they're saying that Thailand normally provides 1/4, but with the factories closed, it temporarily supplied less. If that's the case, then the "but" makes sense in that context, with some implications sprinkled in.

  12. Policy on Of Diamond Planets, Climate Change, and the Scientific Method · · Score: 5, Insightful

    The article hints at this but never says it outright: The reason climate change is controversial among those with little or no scientific background or training while diamond planets are not is because climate change research affects many governmental regulation policies. If the diamond planet idea is wrong, then corrections to theories are made, and the field moves on. If it's right, then it may contribute to the development of helpful technologies and discoveries. But if a climate change idea is wrong, then corrections to theories are made, and the field moves on, and either the world economy has suffered for no reason or people are experiencing famines that could have been prevented. Thus, controversial.

  13. 9:00 am Sunday on When Did Irene Stop Being a Hurricane? · · Score: 3, Insightful

    At 9:00 am Sunday morning, August 28, EDT. According to the Hurricane IRENE Advisory Archive. At that time, it was centered over New York City (it was 40 miles SSW of there an hour earlier). Until then, estimated and measured wind speeds made the system a hurricane.

    If you want to dispute the accuracy of NWS current measurements and estimates, then research how they do it and dispute properly. They use recon aircraft, doppler radar, satellite imagery, balloons, and ships, in addition to buoys and automated surface observation systems, to measure and estimate wind speeds. If you want to dispute the NWS's predictions, then either learn meteorology and forecast models to prepare yourself, or compare past predictions to later observations. If you want to dispute the NWS's warning wording, then compare predicted conditions and their real world impact to the NWS's wording. If you want to dispute the media's hype, then compare their hype to the NWS's warnings, and have fun.

    But do not ask such an amazingly easy to answer question like "When Did Irene Stop Being a Hurricane?" in order to stir provocation, without answering it. And do not look at some buoy and automated surface observation system data and claim there was no hurricane just from that.

  14. Re:Embarrasing on Most People Have Never Heard of CTRL+F · · Score: 1

    Huh, that's nice. I've probably seen that a few times when I try all the F# keys to see what they do in a particular application, and then promptly forgot it. I think I'll keep using Ctrl-F, though, as I frequently have the text I want to search for in the clipboard, and so doing Ctrl-F then Ctrl-V (no need to release the Ctrl key between combos) is faster than F3 then Ctrl-V.

    And on a related note, I like having the Google Quick Scroll extension installed on Google Chrome (not sure if there's something available for Firefox). If a website linked to by a Google search result has any viewabl;e text that was part of the reason that that website came up as a rsult, Google Quick Scroll will let you jump right to it.

  21. Disappointed on TI vs. Calculator Hobbyists, the Next Round · · Score: 3, Insightful

    I am disappointed with TI. My first programming language was TI-BASIC on the TI-83 Plus. My second was assembly for the Z80 processor on that calculator. Both were supported by TI (the program used to transfer assembly programs from a computer to the calculator was produced and distributed by TI). It is the reason I chose to pursue computer science in college, and has made me the happy programmer I am today. It is sad TI does not want to allow today's youth the same opportunity through the same means.
