Title: *the title I chose*

and people would upvote it customarily so that it floats to the top.
What i wonder about is how this scam holds for so long being so easy to test. You attach a simple electricity meter to this and run a lightbulb for a couple weeks, and when you reach the energy spent per unit of device's mass akin to gasoline (say 10 KWh/kg), you are onto something real.
Anyone interested in the subject should read this paper describing two experiments conducted by outside researchers.

Berkeley, California is a "nuclear free zone" as the many signs scattered around the city will announce to those that enter. I guess this machine will not be allowed for sale here.
"As a general bread rule, Germans seem to enjoy a darker or seeded bread."

Yes! One of big arguments against moving somewhere else. It is nearly impossible to get good bread nearly everywhere else in the world.
Although I believe that what you say will be correct in maybe 10 years, currently this is not the situation in my eyes. Currently nobody fears bitcoin, because it is still way too low profile to harm anybody. And although their arguments might be wrong we all agree that bitcoin and even the general idea of crypto money can still fail because of a vast amount of reasons, right? The thing is at the moment no crypto money has a real success. Yes, thousands more people care about bitcoins than 2 years ago, but it's not a critical mass yet.
Don't... don't do that. There are people insisting that you can't buy anything with Bitcoin, you're ruining it for them.
> Many skeptics were left unconvinced. But the customer that the E-Cat was being tested for—which Wired UK says was rumored to be the US military's DARPA—was satisfied, and purchased the unit.

This doesn't mean that DARPA is not a sceptic. It means the unit has passed the simplest test of "not a cardboard box covered in tin foil with a guy going 'Beep Boop' next to it". Now DARPA can buy a single unit and tear it apart to see if there's anything interesting there.

A £1m gamble on interesting is not much for military budgets. I don't think I'd have spent the money - it feels like a scam or a sad delusion - but maybe there's some interesting chemistry even if cold fusion isn't there.

So is UTF-16, by the way.
Wow, that's quite something.

I really feel the tech around batteries needs particular focus, as the one thing computing technology seems to lag on is battery life - I dream of a time where I can charge my laptop once a year and not have to worry about it otherwise.

Perhaps 3D printing of batteries will offer easier iteration on new ideas?

No, apart from the inherent bleaching properties of sodium hypochlorite, the pH of bleach is extremely high - even extremeophiles can't tolerate pH 13-14. Unfortunately neither can human skin, and diluting bleach is a trade off between effectiveness and safety.
As much as I would like your statement to be true:

jquery-2.0.3.js 236K
jquery-2.0.3.js.gz 70K
jquery-2.0.3.min.js 82K
jquery-2.0.3.min.js.gz 29K

Minification pay off a lot even with compression.
Maybe you should read the paper conducting exactly such tests, where researchers concluded the energy density is at least one magnitude above conventional sources.
Not having to join your phone to Google Skynet is a major plus for many people.

Also, many Android devices are in the same boat (pun intended!) as the vendors haven't licensed the proprietary bits from Google.
You can do that in any programming language by, well, not computing unused values.
I feel sick to my stomach as well, all about the artist's heart here, as well as about the respect this one has for Spike Lee (which I admire a lot myself). As an advocate for righteousness, this does come across rather harsh and intimidating so I hope SL reconsiders the contract with the people responsible for this mishap... All the best though, all the best.

Its not so much about editorializing, but rather putting into context.

If e.g. amazon.com is down, that may be news. But a link with the title "Amazon" doesn't convey any information. People will wonder why the OP posted that link.

If the focus is on something on the page, not the page itself, you have to reflect it in the title. Maybe the OP doesn't want to post a trivial tech article, but wants to share that the article has a offensive image next to it.

Maybe the point the OP wants to make is opposite, or tangential to the point of the article. There was a wierd rant from one of the Gnome developers some time ago. I would never have upvoted the page by itself, as it was badly written, and I disagree with its contents. But the given title, which was basically "look, Gnome dev lost his marbles", lifted the post to a meta level, on which I gladly upvoted and shared it.

The current way to do the above is to post a stub on your blog, and link to that, although it is also offically discouraged. I personally think, when it is possible to do something while jumping through hoops, it should just be allowed to do the same thing without the hoops - no one should have to waste time to write a redirection article.
This is why I say I'm at my most efficient when I just don't do any work at all.
Talk about throwing out the baby with the bathwater..

The original article was wrong because it proposed replacing strings with arrays of code points. Clearly, that doesn't work.

This article is wrong because adding more string types just shuffles the problem around. There is nothing "machine consumable" about strings encoded in a certain anglo-centric character encoding! Just don't even think that thought. "abc" is absolutely not more "machine consumable" than "東京". You don't "hash prose" by transliterating text into ascii characters.

It's not impossible to fix the existing string types. Principle of least surprise holds. In cases when it doesn't, the locale is the tie-breaker. E.g. "Scheiße".upper(locale.DE) may be different from "Scheiße".upper(locale.RU).
Jet Capsule: A boat from the future
Having taken up the water transportation niche in the design industry, Italy’s Pierpaolo Lazzirini has unveiled his latest Jet Capsule concept. Measuring 7 by 3.50 meters, the Jet Capsule is more spacious than any other boat with the same length. The Jet reaches speeds of 28 mph using a 325 horsepower engine, however, it can be boosted to a whopping 57 mph with a 350 horsepower engine.

"The researchers found that hypochlorous acid, the active ingredient in bleach, causes the unfolding of proteins in bacteria in much the same was that heat stress or fever does. Those denatured proteins then clump together irreversibly into a mass in living cells, similar to what happens to proteins when you boil an egg, according to the researchers.

"The bacteria aren't totally defenseless, however. Under those circumstances, a protein chaperone called heat shock protein Hsp33 springs to action, protecting proteins from the aggregation effect and increasing the bacteria's bleach resistance. Protein chaperones are generally defined as proteins whose function is to help other proteins."
That's like saying anyone can make money by just making money. It's a null statement!

You are right. But even when you can export, the issue remains that a mentality is developing in which consumers have to pay a lot of money to get something that you could just purchase once in the past.

If we continue along this route we'll slowly but surely have more and more barebone devices that can't do anything on their own, but require expensive subscriptions to do, what used to be, basic things. This also takes away our rights; the Renault example is very strong, you can't drive unless you pay. I'd maybe rather pay the price for the battery and replace it when it breaks, then having to continue to pay and then be stranded 2000km from home when I forgot/couldn't pay.

I think you may have misread Graeber. He is NOT advocating for commodity/debt-free currency. His whole point is that money started as credit - only later was it viewed as commodity, and only occasionally.

Money effectively is both commodity and an IOU. Attempts to force it into one category or another eventually leads to social breakdown.

The key question for our time is how to craft a stable monetary system that is decentralized. We don't know how to do this yet, and Bitcoin is not likely the answer BECAUSE it is finite (which would be catastrophic, as gold was). Crypto currencies can and should grow in experimentation but this one has a fundamental flaw.

The problems arise not from strings, they are well understood computationally, and most languages provide sound functions for working with them. The problems arise when strings are held responsible for the side effects of other functions which manipulate the data within strings.

In particular, problems arise when some function renders a sequence of characters contained in a string [fundamental string operations such as concatenation tend not to be problematic]. These problems are due to the transition from the mathematical certainty of strings to the heuristics of text rendering. The compromises required to map semantics of human writing systems onto strings via Unicode contributes to this problem...glyphs are not necessarily ordered sequentially or without resolution under a context.

This seems like it would really complicate use of a CDN given that page content is now different based on what users have cached. You could look at cookie values and still get some caching, but this would hurt your cache hit rate. It also bars you from using a lot of the cheaper CDNs which won't let you inspect the request deeply enough to efficiently cached based on the cookie.

So if you can't use a CDN or your cache hit rates are much lower, you might end up with slower page loads with technique. But of course I have no data to back this up.
Can you sideload anything on Windows or Apple phones? No. And on most carrier locked Android phones, you have to find an exploit to root your device before they let you sideload apps. So my point, that you are less free today with modern smartphones than you were with your PC under MS dominance in the 90s, stands.

This isn't like some test to pass before changing your oil. It's like requiring Ford's permission to install some fuzzy dice or a custom seat cover.

Well, until about a year ago, Java was on (I'm guessing) 70% of PCs, Flash on > 95%. Now with the shift away from plugins, and the growing importance of mobile, its shrinking quickly.

But! in the brave new world of HTML5 and so on, you still can't assume that everybody has all these features. Either they are stuck on older browsers (at work, or my old laptop that I rarely use), there are subtle implementation differences bewteen browsers (although I have cutting-edge Android devices, the cool demonstrations often don't work nicely in them), or finally the browser is OK, but the computer is too slow.

I only have one computer that can run all this newfangled WebGL stuff at decent speed, and it's my gaming PC at home.

Most of the lights near my towns exit ramp work off of light sensors (dusk to dawn style). There are a couple where the sensor is either too sensitive or angled incorrectly (so it picks up vehicle headlights). As your car approaches, the light turns off. It's rather disconcerting when it happens.

Funny, but I think you finally went too far! Speed is one thing, and not executing a function sure can happen fast, but efficiency is productivity per unit time, and if there is no productivity, it can't be "most efficient". (Yes, I'm a pedant sometimes.)
Snap.svg looks really nice! I meant mainly the Flash authoring tools (Macromedia Flash) are missing. Every idiot used to be able to click together a little animation. It even spawned a new (although questionable) art style of "Flash cartoons".
Agreed this is a problem. Although perhaps it's worth not minifying your JS to gain the speedup from the use of diffs?

Find a different XML parser or adopt a different way of reading the XML (DOM vs. SAX; or just a different library that performs better). I see where you are coming from though. The problem with XML is that it is used to solve problems that it shouldn't be solving - it's a great technology when used correctly (XMPP is a great example of how XML can make other transfer formats look like a dress rehearsal). In most cases, as you said, "global design flaw" - a good indicator that you are abusing XML is if you are not using xmlns attributes and if you do not have multiple namespace (because in that case JSON is simpler, faster and makes more sense).

It's true tat it's been a long time since I played with this stuff, I work out for a circular orbit

Total energy of an orbit is -G mp mS /(2 r)
mp = mass of planet
mS = mass of sun
r = distance of planet from sun

Even though this is a circular orbit, the basic result should be the same: the greater the distance from the sun the more energy the planet has, per unit mass.

I think I understand your basic point, however, which is that whether we speed it up or slow it down we have to do something to the mass, and how much we do depends only on difference of the orbit radii.

But note that adding 100 m/s or subtracting 100 m/s gives two different differences in r.

First thing that pops to mind is jQuery animations vs CSS transitions/keyframe animations, especially on low-powered mobile devices. I guess that's not explicitly jQuery vs JS, but it's still an example of how it can be done far better.

There's also the fact that you don't have to include a gigantic library of functions you'll never use, just to show a box when you click a button. 37kb is way over 10% of my ideal page load for a simple to moderate site.

I don't think $16,000 a month is really that bad if you factor in what type of money a consistent 1 million reqs/sec would probably give you.

1m req/s is:

60 million+ reqs an hour

1.4 billion+ reqs a day

43 billion+ reqs a month

It would be a weird situation to be serving that much traffic but not being able to afford hosting.

It would be cool if someone could estimate the cost of what it would take to sustain 1m reqs/s with dedicated hardware or maybe an unmanaged VPS cluster.

It's less convenient than writing a compiler in Haskell, but then, what isn't? It does give you reasonable type safety, though. (Again, don't say that where a Haskell programmer is listening, but it's at least decent.)
Just like with any language, I don't think you need to "build" one single project, it's more like having enough everyday hands-on experience to be able to choose the right way to implement the logic in the given language. Knowing how to properly use all major classes/functions, being also aware of the less known functions (in php code you'll often see people reimplementing the functionality that's already supported directly in the language, especially when working with arrays and strings), knowing all important gotchas and naturally structuring your code to avoid them... that is what I consider mastering a language...
