SanDisk Releases 512GB SD Card

xfade551 Re:1024-fold (207 comments)

In case you haven't noticed, manufacturers of transistor based memory (flash, SRAM, DRAM, EEPROM, etc.) still use the 2^10 definitions. To this day, I still can't believe the marketers convince IEEE to make up the silly sounding names for the 2^10 definitions. If I had a say in the definitions, I would have tagged on subscripts of 2 and 10 to the end of the units to indicate the difference.

By the way, under both sets of definitions, 1024 bytes = 1 KB = 1 KiB. It's only for MB and higher that it diverges.

How Does Tesla Build a Supercharger Charging Site?

xfade551 Re:That's not quick? (190 comments)

Are those amp values load amps or breaker amps? Just running the raw numbers provided (and neglecting power factor) thats 145320 W coming into the rectifier and 49200 W going out... a whopping 33% power efficiency! 33% efficiency isn't all that much higher than a typical internal combustion engine.

Another problem with all of this is the cable sizes that are required... 120 Amps is 2ga. or (most likely) larger cable. Cables that size start getting heavy and stiff pretty fast.

At any rate, I here Teslas are fun to drive (at least while the charge lasts) and that's all that really matters, am I right?

Giant Greek Tomb Discovered

xfade551 Re:Talk of unit conversions is off the mark (164 comments)

When using computers, there is one way in which English measures are unbiasly superior to metric units, which is that the standard practice that subdivisions of the small length unit (the inch) are base-2 fractions (i.e. 1/2", 3/4", 5/32", etc), rather than decimal (i.e. 11.3 mm, 15.923 mm, 2.71 mm, etc. ...just examples, not conversions). Why is this superior? Numbers are represented in binary on a computer, decimals will not neccessarily convert without a small error. Usually the difference is negligible, but errors can build if you are adding a long series of values or multiplying by large numbers.

I'll concede that weight, volume and the large length measures can be a little confusing though.

Slashdot Asks: Should Schooling Be Year-Round?

xfade551 No summer vacation = No time for major maintenance (421 comments)

One thing that gets missed in this whole year-round school debate is: when is the school going to have time for major maintenance, repairs, and renovations? Many schools are already packed through to the brim (in terms of classroom capacity) so it's not like they can close down an area of the campus/building to get work down while class is in session; construction noise and construction zone safety are major factors too. Ever been on the floor above when a construction worker is using an impact driver into a wafer ceiling?? If you have, you have probably noticed it's louder and more annoying noise for you that for the construction worker. On the safety side, do you really think it's a wise idea to do a crane lift of a large HVAC unit while there are unwatchful, unrulely, or apathetic students down below?

Bad "Buss Duct" Causes Week-long Closure of 5,000 Employee Federal Complex

xfade551 Re:Earthshaking (124 comments)

Google an image search for "siemens sentron busway" (busway is just Siemens' lingo for "buss duct", but "busway" can refer to other sorts of devices, too). There are other manufacturers, but that's just the first model name I remember.

Today In Year-based Computer Errors: Draft Notices Sent To Men Born In the 1800s

xfade551 Re:Technically, it's not a "draft notice" (205 comments)

Technically, the notice is called a "Failure to Register with the Selective Service Notice". I had one forwarded to me after I had already been in the Army 4 years (I enlisted a little before my 18th birthday), and was already serving in Afghanistan. I called the contact number, and the exchange went something like - Me: "Hi,this is Specialist [MyRealName], U.S. Army. I received one of your Failure to Register notices. I'm kinda in Afghanistan right now, what am I supposed to do with it?" Helpdesk person: "Er, umm... our apologies... umm, Soldier. Uh... thanks for serving. We'll update your record. What's your Social?"

We need checkboxes instead of radio buttons on this one.

And don't look at me like that! I live near Seattle where there is plenty of open water and plenty of Indian Reservations to buy the good stuff at.

The lightbulb I've most recently acquired ...

xfade551 Re:Oddball (196 comments)

Just so you know (and a lot of people get this mixed up), 120/240V in the U.S. is not 2-phase power (with the exception of one small hydroelectric served area of upstate NY, which actually has some relic 2-phase generators)! You are receiving single-phase power off a 3-phase transmission system (typically, one residential neighborhood will be on the same phase), with a center-tapped/center-grounded step-down transformer providing service to your home. "Split-phase" is a more appropriate nickname for a center-grounded single-phase electrical system.

The lightbulb I've most recently acquired ...

xfade551 Re:LED bulb replacement (196 comments)

You can purchase LED "tube" replacements for fluorescents. We've been testing them out at my workplace, and, generally speaking, the building staffers seem to like them better than old fluoresent lamps. The catch is that you have to re-wire the fixture and bypass the old ballast module.

2 US Senators Propose 12-Cent Gas Tax Increase

xfade551 Re:Instead of gasoline tax, why not a disel tax? (619 comments)

Diesel (except farm diesel, which is exempted and has a dye additive to distinguish it) currently is Federally taxed, per gallon, identically to gasoline. It used to be taxed at a lower rate, but congress let that one expire during the Clinton administration.

2 US Senators Propose 12-Cent Gas Tax Increase

xfade551 Re:Let's be fair (619 comments)

It's also sitting higher than the estimated combined value of all the earth's gold, silver, and platinum (already extracted and unproven reserves included) which is about $15T (source: National Geographic's "Secret History of Gold"; this special didn't relate that number to U.S. Debt, it was my own observation).

IRS Lost Emails of 6 More Employees Under Investigation

xfade551 Re:Massive conspiracy (465 comments)

So, if it was like the scenario at my workplace, at that same time period we were stuck with an obscenely low (50MB) MS Exchange inbox limit (since bumped to a "whopping" 100MB), which forces you to sort everything to local PST files (which default to encrypted-format), then had lowest-bidder full disk encryption on top of that (quite possibly GuardianEdge). The version of GuardianEdge in use at the time had a nasty tendency to crash harddrives... of my office of 28 persons, all 28 had an unrecoverable harddrive crash during that same time period. To compound things, GuardianEdge would also encrypt external USB drives, but the encryption key was stored on the internal drive. Personnal network partitions were also too small at the time to back anything up to the network.

But, in spite of all this, it's still way too "convenient" that these emails were lost.

Canadian Court Orders Google To Remove Websites From Its Global Index

xfade551 Fix it with external links (248 comments)

I don't have time to do it myself, but with the information provided in the court case (without possessing this "Schedule A" that I presume is sealed by the court), simply that the defendants are "Morgan Jack, Datalink 4 and Datalink 7", I think a motivated Slashdotter could effectively rebuild and repost the URL list before Google (maybe) de-lists them.

Are US Hybrid Sales Peaking Already?

xfade551 What are people buying? ... (377 comments)

At least around my area, I'd say we are buying Mustangs, Cameros, Corvettes, Challengers, and Chargers. (yes, I phrased that "we" for a reason) Other people are buying F150s, Silverados, Rams, and Titans.

Microsoft Runs Out of US Address Space For Azure, Taps Its Global IPv4 Stock

xfade551 Re:Not sure what they mean... (250 comments)

I pretty sure this just means Microsoft ran out of IPv4 addresses that they bought for the specific purpose of their Azure service, so they are now "borrowing" addresses from their other address pools. This also means their Azure services are no longer one continuous block of addresses.

Astronomers Solve Puzzle of Mysterious Streaks In Radio Images of the Sky

xfade551 Re:Cyclotron Radiation? (66 comments)

Let's see, meteor generates a plasma trail... that would be moving charged particles (both positive and negative). Moving charge means a changing electric field. A changing electric field causes a changing magnetic field, so we have a changing electro-magnetic field... i.e. radiowaves. The ions in the plasma trail don't stay that way, the electrons get recaptured at some point, which means a photon will be discharged, i.e. a radio wave-packet. As to frequency, just put a couple grad students to write a program to calculate photon emission frequencies of a couple million different ion configurations, and they'll probably find the correct correspondence somewhere in there.
