kevilleon Student accidentally invents phone battery capable of 200k recharges

I fear that as devices shrink there's simply not enough room inside many of them for a workable compartment space that would allow for battery exchanges.

kevilleon On an Island Named for Ice, the Poets Are Just Getting Warmed Up

This reminded me of one of Björk's interview responses from nearly two decades ago [1]:

"Yeah, we hold the world record for the population with the highest literacy rate. No art, no painting, no dance, no history of anything but literature. Viking sagas. If teenagers in Iceland are young and angry they don't form punk bands, they write poetry. And then they get drunk and shout it at each other. Not because they're so intelligent, as English people seem to imagine you must be if you're connected with books, it's just a cultural thing."

kevilleon Aggressive design caused Samsung Galaxy Note 7 battery explosions

To a machinist, a tenth of a millimeter is a yawning gulf.

kevilleon Aggressive design caused Samsung Galaxy Note 7 battery explosions

It's not called out specifically in the prose of article, but I think the dimensions overlaid on the image show quite a bit of intentional space left for tolerance around the sides of the battery, and they mention the walls formed by the aluminum carrier around the battery pack. This is pretty clearly intentional "walling off" of the battery from the rest of the PCB, and (I assume) is more protection than other devices were designed with.

If my assumption is correct, though, I find it strange that article footnote seems to contradict this by essentially saying the engineers didn't give enough space around the 'front' and 'back' of the battery. Did they protect the PCB and battery from each other, and fail to protect the battery from the front and back of the phone?

I am a (somewhat myopically) JavaScript-focused developer, so I admit my own domain-specific bias here, but `chaijs.com` is the first Google search result for both "chai code" and "chai library".

I don't mean to antagonize, since any more detail would give away the answer -- but a qualified candidate should recognize various encoding outputs, even if they can't immediately identify the specific encoding scheme.

Apple's iCloud Drive has a decent web interface for the non-Apple subset of "any device", and otherwise seems to offer what you want. Curious if you had other reasons it doesn't meet your needs.

kevilleon King Tut's dagger blade made from meteorite, study confirms

One could also imagine an event where a small cluster of meteorites moving through the solar system did not get pulled into the asteroid belt, but instead showered the Earth for a few decades, or even a century, with a few impressive streaks in the sky every year. Even if only one landing site in ten was identified, you may have dozens of sources of pure ore.

kevilleon Doug Crockford's Seif Project – how to save the web [video]

> is a totally incorrect thing to do in practice

Can you elaborate on this? I understand that there are many sources of entropy for random number generation, and it seems like this would be as good a way as any to store* a pool of some for future use.

(* Is it that the storage is the inherent problem?)

kevilleon Doug Crockford's Seif Project – how to save the web [video]

The talk linked from this post was pretty easy to digest, perhaps you should watch the whole thing before asking what it's about?

The television-standards bit, while probably longer than necessary, was meant to drive home the point that the responsibility for improving application security on the Internet should not be placed with the user.

kevilleon Doug Crockford's Seif Project – how to save the web [video]

> there seems to be no shortage of awesome websites that serve their purpose

This is not an effort to defeat the web, just to provide a security-oriented application platform that sits alongside it.

It appears Crockford's time at PayPal has led to this focus?

Technical Mastery is not Art, it's Technical Mastery. There's nothing inherently creative in having mastered a craft. Technical Mastery is a comparative metric when a given output has been determined to be artistic.

Producing a "selfie" is, by definition, working within an artistic constraint, and when I read your post I had to assume that we had already seen many "selfie artists", which seems to be the case:

kevilleon The gear seer: analyze your bicycle drivetrain

I avoided mentioning it because I couldn't remember off the top of my head when writing the above comment, but Pinion also makes a gearbox that sits next to the crankset and offers up to 18 gearing choices!

kevilleon The gear seer: analyze your bicycle drivetrain

In my opinion, this visualization is not particularly compelling if you don't already know what you're looking at, and I can relate to your sentiment of confusion.

This is a tool for analyzing and comparing differences between drivetrain setups. A bicycle drivetrain is typically composed of a single gear, or two or three gearing choices "up front" (on or near the crankset) and either a single-speed "rear", or anywhere from two to 30 (!) [1] selectable gears at the rear hub.

The various "output" modes from this tool are all derived from the Gear Ratio, usually simply the ratio of the number of teeth "up front" to the number of teeth "in back" for any given selected gear.

By entering multiple drivetrain setups, you can quickly compare overall range between different drivetrains. You can also see the "steps" between different gears within a given drivetrain, which tells you how many pedal cadence choices you'll get within a given comfort zone for the bike's intended riding purposes.

Holy Hell, this is the most interesting bit of the whole article. To think that a company like FedEx in its young prime could have an endeavour* like that completely disrupted by such a _force majeure_... great tidbit in what is otherwise a bit of a stale article.

kevilleon Amazon Shows Off New Prime Air Drone with Hybrid Design

In San Francisco, at least, the trucks' cargo areas are locked and reasonably well-secured when the vehicle is not attended, to reduce the opportunity for exactly this crime. I'm sure there are areas where sniping a few boxes from a truck as the driver is otherwise occupied is not so difficult, but that's not something one could expect to get away with repeatedly.
