Comment Re:Propagation delay ??? (Score 1) 720

High-quality conductors can improve performance, but only a bit, in this case; when it comes to length the problem isn't resistance, it's the capacitance of the wire (which is a function purely of length). The longer the run length the higher the current needs to be to achieve the same voltage. Ethernet's run length limits are based on calculations to determine the point at which the signal in dB is too low to be reliably received. The latency he experienced probably wasn't to do with the length itself, but with the fact the packets had to be retransmitted multiple times before they were successfully received.

Submission + - Cops 101: NYC High School Teaches How to Behave During Stop-and-Frisk 1

HughPickens.com writes: Kate Briquelet reports in the NY Post that Principal Mark Federman of East Side Community HS has invited the New York Civil Liberties Union to give a two-day training session to 450 students on interacting with police. “We’re not going to candy-coat things — we have a problem in our city that’s affecting young men of color and all of our students,” says Federman. “It’s not about the police being bad. This isn’t anti-police as much as it’s pro-young people ... It’s about what to do when kids are put in a position where they feel powerless and uncomfortable.” The hourlong workshops — held in small classroom sessions during advisory periods — focused on the NYPD’s stop-and-frisk program and how to exercise Fourth Amendment rights when being stopped and questioned in a car or at home.

Some law-enforcement experts say the NYCLU is going beyond civics lessons and doling out criminal-defense advice. “It’s unlikely that a high school student would come away with any other conclusion than the police are a fearful group to be avoided at all costs,” says Eugene O’Donnell, a former police officer and professor at John Jay College of Criminal Justice. NYCLU representatives told kids to be polite and to keep their hands out of their pockets. But they also told students they don’t have to show ID or consent to searches, that it’s best to remain silent, and how to file a complaint against an officer. Candis Tolliver, NYCLU’s associate director for advocacy, says was the first time she trained an entire high school. “This is not about teaching kids how to get away with a crime or being disrespectful. This is about making sure both sides are walking away from the situation safe and in control.”

TRIM is already implemented in firmware; what the OS sends to the drive are "hints" indicating blocks which have become free and require clearing. Without the OS sending those hints I don't see how the SSD would know which blocks are safe to clear; doing so requires reading the drive's file system, which is why the OS has always been involved.

It's a declarative sentence, any conditions narrowing scope should have been included in the (absent) part of the sentence called a clause. You're confusing written English with conversational English. That sentence would have been read and understood if one person said/typed it to someone else during an interactive conversation; using that type of sentence structure on a forum/group conversation thread is ambiguous and can lead to multiple contradictory meanings.

It's a declarative sentence, the scope is global unless a clause is used to restrict it. Likewise, the use of "this" (as pronoun) in this context requires that the noun to which is refers be used *in the same sentence* because otherwise it renders the sentence so ambiguous as to be useless -- two people can read the same sentence and come away with opposing messages.

You don't even have to look as far as eBay, those same counterfeit cards are also available on Amazon.com. You can even get them "Fulfilled by Amazon"; I called to complain and was told "we just distribute what the sellers send to our warehouse" -- if that argument wouldn't keep a fence out of prison why should Amazon get to use it to profit from fake goods? Also, even though you can still get 4GB microsd cards every fake I've seen has been an 8GB one; do you think perhaps that's because it's easier to add the "12" without needing to scrape off the "4" first?

Submission + - A Band-Aid that could suck bugs out of your wound (sciencemag.org)

sciencehabit writes: Scientists have made progress towards a band-aid like device that can literally suck bacteria out of wounds. When they placed nanofibers in a petri dish of Staphylococcus aureus, a bacterium involved in chronic infection, the bugs quickly attached themselves to 500-nanometer-wide fibers, but hardly onto fibers with larger diameters. When the researchers coated the nanofibers with different compounds and tested them on the bacteria Escherichia coli, also responsible for chronic wounds, the bugs formed bridges on fibers coated with allylamine, a colorless organic compound, but stayed away from fibers coated with acrylic acid. The researchers, who plan to test the meshes on composites that resemble human skin, hope that they will eventually lead to smart wound dressings that could prevent infections. Doctors could stick the nano–Band-Aid on a wound and simply peel it off to get rid of the germs.

Submission + - Senate may vote on NSA reform as soon as next week (dailydot.com) 1

apexcp writes: Senate Majority Leader (for now) Harry Reid announced he will be taking the USA FREEDOM Act to a floor vote in the Senate as early as next week. While the bill, if passed, would be the first significant legislative reform of the NSA since 9/11, many of the act's initial supporters have since disavowed it, claiming that changes to its language mean it won't do enough to curb the abuses of the American survailence state
