SSD-HDD Price Gap Won't Go Away Anytime Soon

Jeremi Re:not really (236 comments)

well, the thing is that hdd's keep getting faster and bigger too. 100 bucks buys you 3TB. for 300 bucks you can get 9TB.

That's true; OTOH for personal use, there's often no benefit to buying more capacity since you won't be using it anyway. For example, my disk usage never reaches the 250GB mark, so for me there is little point in paying for more capacity than that.

Which means my choice is between a dirt-cheap (but slow) 500GB spinning disk, and a not-so-cheap-but-still-affordable (and FAST) 500GB SSD, and since I don't like waiting for my computer to do things, I'll choose the latter.

As both SSDs and hard drives get cheaper, my next 500GB drive of choice will be cheaper yet; the fact that I could buy a cheaper and/or larger spinning drive instead doesn't matter much since then I'd have to use it (zzzz)â¦

Other people will have higher thresholds, of course, but as the technologies mature they'll reach a point where most shoppers will find that any drive's capacity is "sufficient" and then their choice will depend solely on performance and price.

This 1981 BYTE Magazine Cover Explains Why We're So Bad At Tech Predictions

Jeremi Re:It was a "joke" back then (275 comments)

Yep. a "computer" using levers and pulleys to steer a starship. :-)

To be fair, any autopilot mechanism is going to have to physically move something at some point, if it wants to actually affect the behavior of the ship and not just make computations about it.

Asimov's mistake was thinking that these actuators would be the same ones used for manual piloting, rather than a separate set that was hidden somewhere else in the spacecraft.

Can You Buy a License To Speed In California?

Jeremi Re:selective enforcement at it's finest. (324 comments)

All of which I'm sure are mostly free from traffic tickets -- just not something you can purchase on a whim. Survived Pearl Harbor? Fuck it, Mr. Have a nice day.

I know gut instinct is what the Slashdot comments section runs on, but what actual, non-anecdotal evidence to we have that police officers give preferential treatment to people with these license-plate holders?

Has any of this actually been studied in a scientific way, and if so, what were the results?

Heartbleed Coder: Bug In OpenSSL Was an Honest Mistake

Jeremi Re:Whatever you may think ... (444 comments)

Did he really have any other option here? Even if he did it on purpose, would he admit it?

Well, you have to admit that a response of "HAHAHA SUCKERS" would be a memorable one. I wonder if he considered doing that?

Heartbleed OpenSSL Vulnerability: A Technical Remediation

Heartbleed OpenSSL Vulnerability: A Technical Remediation

Jeremi Re:Situation is a Shambles (239 comments)

JVM's are written in C and C++, the CLR is the same. Which managed language do you suggest to use that was not built with C?

The point isn't to eliminate C code entirely, but to minimize the number of lines of C code that are executed.

If (statistically speaking) there will are likely to be N memory-error bugs per million lines of C code, then the number of memory-error bugs in a managed language will be proportional to the size of the interpreter, rather than proportional to the size of the program as a whole.

Add to that the fact that interpreters are generally written by expert programmers, and then they receive lots and lots of testing and debugging, and then (hopefully) become mature/stable shortly thereafter; whereas application code is often written by mediocre programmers and often receives only minimal testing and debugging.

Conclusion: Even if the underlying interpreter is written in C, using a managed language for security-critical applications is still a big win.

Heartbleed OpenSSL Vulnerability: A Technical Remediation

Jeremi Re:Situation is a Shambles (239 comments)

It was Robin Seggelmann that submitted this bit of buggy openssl code. He either works for the NSA or is grossly incompetent...

Or he made a dumb mistake, as 100% of programmers have done and will do again in the future. Anyone who expects programmers (even the best programmers) to never make mistakes is guaranteed to be disappointed.

The real issue here is that the development process did not detect the mistake and correct it in a timely manner. Code that is as security-critical as OpenSSL should really be code-reviewed and tested out the wahzoo before it is released to the public, so either that didn't happen, or it did happen and the process didn't detect this fault; either way a process-failure analysis and process improvements are called for.

Navy Debuts New Railgun That Launches Shells at Mach 7

Jeremi Re:Difficult to defend against (630 comments)

However, how do you shoot down a hunk of metal traveling at mach 7 toward your ship?

I think I'd like to use a rail gun to shoot a hunk of metal at it at mach 7. Assuming I don't miss, the result should be a single projectile, twice as large, that drops straight down into the ocean. Right? ;^)

Smart Car Tipping Trending In San Francisco

Jeremi Re:San Francisco: crazy again (371 comments)

Three cars tipped over is "crazy" and a reason to avoid a place?

No; but this certainly moves the crazy-needle over a bit.

Smart Car Tipping Trending In San Francisco

Jeremi Re:Rreachtions (371 comments)

3) Someones insurance rates are going up

Anyone know how much damage a Smart Car can be expected to suffer when tipped like this?

(I'd imagine some crush/scratch damage to whatever body panel(s) are now supporting the car's weight, plus my co-worker says that various fluids are likely to drip out into places they aren't supposed to be)

Tesla: A Carmaker Or Grid-Storage Company?

Jeremi Re:There is already a Tesla home battery pack (151 comments)

NOT zero outlay. you still pay just about what you'd have payed the utility anyway...

Not if your roof has good sun. My condo building's HOA (in Southern California) was previously paying the local power company about $1000/month for electricity. We had SolarCity install solar panels on the roof under a Power Purchase Agreement; now we pay about $750/month for electricity. So that's about $12,000 in savings since 2010, and the HOA never had to spend a dime.

And they get to build an indistrial plat in and about your property

Yes, they got to install their solar panels on our roof. That hasn't been a problem for anyone.

An SSD for Your Current Computer May Save the Cost of a New One (Video)

Jeremi Re:it's true (353 comments)

I had a friend who was adding memory to his Macbook to also add a SSD. Those two additions made "amazing" speed improvements. With the prices of SSD's it is a no brainer. No computer should be without it!

I'll add that if you get a Mac with the Fusion Drive setup (or reconfigure your Mac to use that feature), things are even nicer, as you no longer have to manually shuffle your "hot" data onto or off of the SSD drive. Instead, whatever data you access often will automatically migrate to the SSD, and "cold" data that you don't access often will automatically migrate to the spinning disk (if necessary). Works great!

(Note that this does mean that if either the SSD or the spinning disk die, you've probably lost your data on both drives -- but that's what backups are for. Pay another $60 for a basic external drive for Time Machine to use, and you're golden)

Russian GLONASS Down For 12 Hours

Jeremi Re:Warning Shot (148 comments)

My spelling mistake was just a mistype on Samsung's stupid virtual keyboard. But if you confuse "there" with "their", it means that, for you, use of english is nothing more than parroting a bunch or sounds

ROFL.... "my mistake was the computer's fault, your mistake was a sign of your intellectual inadequacy".

Or perhaps the OP also has a virtual keyboard (or some other not-terribly-bright auto-correct mechanism) that auto-converted a slight misspelling of "their" (e.g. "ther") into "there" and wasn't noticed in time.

But don't let that stop you from telling the OP how superior your language skills are to his. You clearly are a prodigy, that's why you get to post to Slashdot.

Russian GLONASS Down For 12 Hours

Jeremi Oops (148 comments)

"In an unprecedented total disruption of a fully operational GNSS constellation, all satellites in the Russian GLONASS broadcast corrupt information for 11 hours [...] This rendered the system completely unusable to all worldwide GLONASS receivers."

Ok! Ok! I must have, I must have put a decimal point in the wrong place or something. Shit. I always do that. I always mess up some mundane detail.

NYU Group Says Its Scheme Makes Cracking Individual Passwords Impossible

Jeremi Re:Running memory (277 comments)

This is just another one of those "make this link in the chain even stronger because once someone broke through it" forgetting that there are dozens of other weaker links that simply have yet to be targeted.

If you can think of a way to strengthen all of the links simultaneously, by all means post it and/or start a company and get rich selling your perfect-security technique.

If, on the other hand, you can't, then strengthening the links one at a time may be the best we can do. Unless you think it's better to leave them unnecessarily weak?

NASA Can't Ethically Send Astronauts On One-Way Missions To Deep Space

Jeremi Re:Ethical is irrelevant. (402 comments)

Exactly because Japan sent old men into Fukushima's reactor, knowing the risk and offering hefty sums for their descendents.

Can you provide a reference for this? Because I can't find any evidence that it actually happened. (I know some old men volunteered to go, but I can't find any evidence that TEPCO took them up on their offer)

NASA Can't Ethically Send Astronauts On One-Way Missions To Deep Space

Jeremi Re:robots (402 comments)

And you know this how? It's not like we've ever experimented with living on another planet or anything.

Sure we have (by approximation, anyway):

  1. Astronauts living in the Space Station start losing bone and muscle mass after a few weeks.
  2. Researchers living in isolated conditions in Antarctica start suffering depression and other mental problems after a few months.
  3. Volunteers living in BioSphere 2 found that their biological life support systems failed and they had to 'abandon ship' after 24 months.

Note that all three of the above represent "easy" scenarios, where help and/or an emergency return to Earth is always minutes, hours, or days away. On Mars (or en route to Mars), help from or escape to Earth would not be a likely option.

How interested are you in Virtual Reality tech?

Jeremi Re:VR again? (202 comments)

Oh, we all know what the killer app is: the same one that vaulted the VCR and the internet to ubiquity.

Why bother with VR goggles? Cut out the middleman/women and just develop a headset that directly stimulates the user's brain's reward center. With that you can corner not only the porn market but the cocaine/marijuana market and the flappy-bird market as well.

Bitcoin's Software Gets Security Fixes, New Features

Jeremi Re:LOL .. 0.9.0? (173 comments)

Because people don't trust software like Microsoft Windows or Epic Systems's EPIC or Autodesk...no sir, no one trusts commercial software.

An excellent refutation of a point that was never made. No one would trust closed-source *BitCoin* software. Hell, a lot of people don't trust open-source BitCoin software, which they can audit as thoroughly as they want.

Tell me, when you get done fapping to open source is the napkin you use for clean up GPL compatible?

Tell me, does being an obnoxious prick on the Internet improve your life in any tangible way?

Samsung SSD 840 EVO MSATA Tested

Jeremi Re:I would like to know (76 comments)

Mac OS X recently added very aggressive disk caching (it will use any free memory for disk caching), and it dramatically improves performance, even on machines with super fast SSDs.

Recently? I was under the impression that this was how MacOS/X (and indeed most non-ancient flavors of *nix) had always worked. Was I mistaken about that?
