Sapphire Glass Didn't Pass iPhone Drop Test According to Reports

TeknoHog Re:Ion strengthened? (200 comments)

Regular glass doesn't contain any ions, in the same way that regular vegetables don't contain any genes.

Amazon Is Killing Off Its Free P2P Money-Transfer Service WebPay On October 13

TeknoHog Re:Guess I'll have to use google wallet or paypal (34 comments)

I dipped my toes into the Bitcoin world, just to say I'd done it... My $0.1245 worth of bitcoin is now worth $0.0955 Yeah, that's a lot better than keeping my money in a bank...

It's a good thing they value it in dollars, because the value of a dollar never changes, and that's how we know our money is safe in a bank.

Why Atheists Need Captain Kirk

TeknoHog Re:Golf logic (857 comments)

IMHO, everything that people do can be explained by the ultimate goal of enjoying. If you do something because it makes rational sense, then perhaps you're the kind of person that enjoys rationality. I certainly get a kick out of doing math and science, and I try not to make the excuse that I'm doing it for some obscure higher purpose. People also tend to feel good when they help others, it's just what has kept mankind alive. If you say you exercise to keep yourself fit for work, then perhaps it's the work/money/status that you just happen to enjoy.

It's a good point about values, though. The question "why" is generally meaningless as it only leads to other questions "why", but the chain can end at some ultimate value -- I do $x because of money/friendship/hookers/blackjack -- but values are personal, and don't necessarily mean anything more than "I happen to enjoy money/friendship/hookers/blackjack, and that's that. In fact, forget the money and the friends."

UCLA Biologists Delay the Aging Process In Fruit Flies

TeknoHog Re:Great... (82 comments)

Slowing the aging process doesn't add 20 years of the worst health at the end of the life but would extend each portion of the process.

IE, if the aging process was truly slowed 30% you'd get 30% longer years at 30, 40, 50 or whatever, not 20-25 years extra in the shape you'd be at 90.

I guess it depends on when this technique is applied. If you're an old geezer now, chances are you won't enjoy any more years with the 20-year-old-you's physique.

3 Short Walking Breaks Can Reverse Harm From 3 Hours of Sitting

TeknoHog Re:What's "Easy" About This? (154 comments)

If the boss is more interested in accumulating a set number of hours sitting down, as opposed to getting productive work done, then perhaps it's time to get a new job.

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

TeknoHog x86? (47 comments)

As this wasn't clear from skimming the articles, should I assume this is the old 32-bit x86 or x86-64? Because the latter has been around for 11 years, which is a geological time in computing, and we should really move on. Of course for something really embedded you'd want an ARM or a microcontroller, so there would be little point in keeping the x86 32-bit.

Paypal Jumps Into Bitcoin With Both Feet

TeknoHog Re:What can possibly go wrong? (134 comments)

Bitcoin is a technology that solves real-world problems, it's not some fancy collectible. If you don't care to find out and appreciate the tech, then what are you doing on Slashdot?

Paypal Jumps Into Bitcoin With Both Feet

TeknoHog Re:IS *NOT* ANONYMOUS (134 comments)

It depends on what you mean by altcoins. There are several newer cryptocurrencies with a fresh start, instead of cloning the Bitcoin codebase and changing a few parameters/algos, and these take the privacy aspect to a new level. I'm mostly familiar with Boolberry and Monero, both of which share a common Cryptonote ancestry.

However, Bitcoin's cash-like privacy is probably good enough for many people. You can trace the movements of cash via serial numbers, but this in itself is a fair amount of work, and you also need to figure out connections between the serial numbers and specific people. It's pretty much the same with Bitcoin, the hard work is in finding these connections, and if you use something like Tor, or otherwise know what you're doing, you can enjoy a cash-like privacy.

Paypal Jumps Into Bitcoin With Both Feet

TeknoHog Re:I started wondering... (134 comments)

Bitcoin was the first cryptocurrency, released over 5 years ago, and it provides roughly cash-like privacy if you know what you're doing. In the meantime, other cryptocurrency projects have developed the privacy aspect much further, for example Boolberry and Monero.

Paypal Jumps Into Bitcoin With Both Feet

TeknoHog Re:What can possibly go wrong? (134 comments)

It just might work. Hell, people once bought pet rocks.

I was going to buy some of the pet rocks, but I heard the latency really sucks when using them for international money transfer, it was, like, way over 10 minutes to other continents. The privacy and fungibility aspects were also questionable. I wonder if they would be good for beating some clue into people who don't understand Bitcoin...

Surprise! More Than Twice As Much Mercury In Environment As Thought

TeknoHog Re: mercury in CFLs is a net good (173 comments)

You obviously know nothing about electronics and magic smoke

Good point -- it's been a while since I've had a puff of that, if you know what I mean...

Seriously, though, I'm picturing a scenario where you accidentally drop a CFL or LED. Besides the mercury vapour issue, it's also nice that one of these stays fully functional after a drop.

When you accidentally a LED, does it immediately release toxic fumes in the air for everyone to inhale? Also, see the sibling post about e-waste.

Ask Slashdot: What Are the Strangest Features of Various Programming Languages?

TeknoHog Re:Lua[0]? (725 comments)

The positional argument for starting with 0 makes sense in C, because it's such a low-level language. It makes sense to expose this low-level view on arrays so you can do things like pointer arithmetic.

For anything higher-level, you'd think the language should make things easier for people who deal with everyday countable items. But even in an otherwise nice high-level language like Python you can find some thoroughly messy array logic, because it basically takes the positional idea even further. While a[0] is the first item, a[0:2] is a range of the first two items, instead of three. The logic is called slices: you start at position 0, which is just before the first item, and end at 2, just after the second one. You've spanned a distance of 2, over the first 2 items.

Ask Slashdot: What Are the Strangest Features of Various Programming Languages?

TeknoHog Re:Lua[0]? (725 comments)

Physicists and mathematicians have indexed, say, vectors, starting with 1 for ages, except in recent times where sometimes they use 0 for very special reason (like chapter 0 in a book).

One common example of vector indices is in relativity. Since we traditionally used indices 1 to 3 for spatial dimensions, it made sense to keep them that way. The spatial dimension was given index 0 probably to denote its special/fundamental position (e.g. energy in the energy-momentum vector).

The traditional programming language of scientists, Fortran, starts its arrays with 1 by default, but it can also be instructed to start wherever you want. For example -n to +n is sometimes quite convenient.

Ask David Saltzberg About Being The Big Bang Theory's Science Advisor

TeknoHog Re:Geeks AND Nerds (226 comments)

Also, considering something like Star Trek, there is some comfort in imagining a society where intellect and honesty are rewarded rather than ridiculed. Which, of course, can be a central aspect of speculative fiction; how far can an ideal geek society go, or do you need someone to be an asshole to take action in the end.

However, I agree with the OP to some extent. As a science/math/electronics/programming/music geek, I've never understood the stereotypical geek fascination with games, comics and other plasticky entertainment. Reading books I can understand, collecting superhero figures not that much.

Microsoft worms to patch software

TeknoHog TeknoHog writes  |  more than 6 years ago

TeknoHog writes "According to New Scientist, Microsoft researchers at Cambridge, UK are studying the use of computer worms for spreading software fixes and fighting malevolent worms. From the article: "Software patches that spread like worms could be faster and easier to distribute because no central server must bear all the load." Not that there aren't other ways to avoid the server bottleneck, even from Microsoft itself."

TeknoHog writes "European scientists have developed a system for tracing the position of fingers on any surface. From the New Scientist article: "Two or more sensors are attached around the edges of the surface. These pinpoint the position of a finger, or another touching object, by tracking minute vibrations. This allows them to create a virtual touchpad, or keyboard, on any table or wall.""
