Intel Releases SD-Card-Sized PC, Unveils Next 14nm Chip

Agripa Re:Pricing? (47 comments)

That was one of the first things I checked. I has neither video nor audio interfaces and apparently no peripheral interface except for USB and it is not clear how that is hooked up. In theory Ethernet could be added via USB but that is already my reason for not using the Pi.

It is not a replacement for the Pi or Beagle Bone.

Paypal Jumps Into Bitcoin With Both Feet

Agripa Re:Taxed when you spend, not just when you sell (134 comments)

So what happens when you sell coins using LIFO/FIFO and take a loss?

I assume you may not combine losses with gains and report the difference since the IRS made that ruling that gambling in one session has to account for them separately so you pay taxes on winning hands without accounting for losing hands.

Some Core I7 5960X + X99 Motherboards Mysteriously Burning Up

Agripa Re:HCF (102 comments)

I gather however that this is plain incompetence (Dunning-Kruger-Type) with regards to the voltage regulators. Switching voltage regulation is really hard to do right unless you over-engineer seriously. You can get all sorts of bizarre effects, including a puff of smoke.

I appreciate the irony of you mentioning the Dunning-Kruger syndrome with your statement. Switching voltage regulation has been around for over 30 years and isn't much of a mystery. Since the early motherboards started reducing voltages from 5v down to 3.3v (and below), every motherboard has had on-board voltage regulation. It's hard to believe that something as fundamental as a switching regulator would suddenly exceed the engineering skill of the motherboard designers.

Switching voltage regulation has been around longer than that but point-of-load switching voltage regulation is more recent and the impedance, power levels, and regulation requirements of these POL switching regulators are cutting edge for a consumer level product.

How the Outdated TI-84 Plus Still Holds a Monopoly On Classrooms

Agripa Re:HP vs TI (359 comments)

I have had the same experience with my HP-48 and HP-50g but from the lender's point of view. A short pause ensues while they examine it and then they hand it back saying, "Um, no thanks."

How the Outdated TI-84 Plus Still Holds a Monopoly On Classrooms

Agripa Re:RPN FTW (359 comments)

Can anyone tell me how the HP50 series compares to the HP48 in that regard?

I replaced my HP-48 with an HP-50g and have no regrets. They fixed the tactile button problem.

The LCD and battery configuration are improved over the HP-48 series and it has micro USB and SD card support.

How the Outdated TI-84 Plus Still Holds a Monopoly On Classrooms

Agripa Re:TI calculators are not outdated, just overprice (359 comments)

The TI-83/84 is used not because it's superior, but because that's the calculator all of the high-school math books have the buttons shown for.

I actually consider this a disadvantage as illustrated by the following conversation which has occurred more than once:

Dude: Hey, may I borrow your calculator?
Me: Sure, here it is.
*I hand over my HP-48 calculator.*
*Dude is silent while examining calculator.*
Dude: Um, no thanks.
*Dude hands back calculator.*

How the Outdated TI-84 Plus Still Holds a Monopoly On Classrooms

Agripa Re:TI calculators are not outdated, just overprice (359 comments)

I find the current HP-50g to be an adequate replacement for the HP-48. The screen is nicer, the keyboard is good, and its battery configuration is superior.

Agripa Re:TI calculators are not outdated, just overprice (359 comments)

The black and white LCD screen they used on the HP-50g is an improvement over the screen on the HP-48. It takes 4 x AAA instead of 3 x AAA which somewhat makes up for the lower power efficiency of its ARM processor.

Invasion of Ukraine Continues As Russia Begins Nuclear Weapons Sabre Rattling

Agripa Re:Sigh... (789 comments)

Well he drops a nuclear weapon on Ukrainian territory and he's not going to have ANY friends in that area anymore.

If he does that, then the Memorandum on Security Assurances would require us to seek action from the UN. Maybe they would send Putin a strongly worded letter.

Invasion of Ukraine Continues As Russia Begins Nuclear Weapons Sabre Rattling

Agripa Re:Sigh... (789 comments)

One of the terms of Ukraine's independance was that they give up the nukes they had left over from the break up of the USSR, but their supposed pay back from that would be protection from NATO if Russia were to invade.

The treaty has no such requirement and does not mention NATO at all.

U.S. Senator: All Cops Should Wear Cameras

FBI Investigates 'Sophisticated' Cyber Attack On JP Morgan, 4 More US Banks

Agripa Re:Honest question from a non-USian (98 comments)

The FBI also uses the excuse that the crime *might* have crossed a state line or border. I expect at some time in the future they will add, "The crime may have affected interstate commerce or involved items or materials that may have crossed a state line."

MIPS Tempts Hackers With Raspbery Pi-like Dev Board

What makes the Pi attractive is relative openness.

Reformatting a Machine 125 Million Miles Away

Agripa Re:Alternative Title (155 comments)

I would imagine that the system probably boots itself off of a ROM chip that has a routine for receiving data from Earth and storing it in RAM and then flashing that data onto the flash chip.

I wonder if the ROM would actually be a floating gate ROM instead of mask ROM or fuse based PROM in which case it would be more like EPROM or NOR Flash.

Does anybody even make mask ROM or fuse based PROM any more?

Reformatting a Machine 125 Million Miles Away

Agripa Re:ECC? (155 comments)

ECC use is standard with all flash storage. Flash is so unreliable that it can't be used without it, and it has nothing to do with the hard radiation environment on Mars.

NOR Flash does not normally use ECC and has reliability closer to that of EEPROM than NAND Flash.
