One of the GC columns has a chiral stationary phase. Chromotography works whether the carrier fluid is a liquid or a gas. The real problem with gas chromotography is that amino acids have a low vapor pressure. They seem to be chemically functionalizing them to improve the volatility.

I can only imagine how much hairier these diagrams become if generated from code instead of English/html. Even for the best case scenario of "The Robot" combined with an "ergonomic" layout like dvorak or colemak, the right pinky area would be a tangle of deep purple. If the diagrams were updated to include backspace key usage, the mess only gets worse.

I couldn't find a typing tutor that addressed the difficulty of typing the symbols in code, so I created a webapp called http://typing.io. It allows programmers to practice typing open source code instead of English or drills.

But wouldn't it be so much nicer if there was no DRM on e-books. That's a law worth lobbying.

And for the record. Norwegian law states that you can freely distribute anything you own to a few friends and also make backups of it. DRM is technically illegal in Norway, but no one has brought a case to court over it yet.
Not all of Europe. It certainly isn't allowed in the UK but we don't have a levy on recordable media. It isn't even legal to rip music to listen to on a computer or an mp3 player. Not that this law is widely followed (or to my knowledge enforced).

That would be a foolish bet. The value of the acquisition is known to have been in the low double digit millions. Probably 12-15. There were two founders, plus a third member of the team at the time of acquisition, and very little dilution from investment...the math is pretty easy.

I don't think most consumers have really thought the whole thing through. Anecdotally I would say most people don't back up files without DRM, e.g. digital photos. I'm sure for everybody reading this comment it seems really obvious that you would want to back up your photos. If the average consumer doesn't understand the very real possibility of total data loss and losing all of those photos, why would they even consider the downsides of purchasing and downloading e-books onto a single device?

Granted I'm mostly playing devil's advocate here, but I think it's entirely silly to expect people to know things that are very firmly technical knowledge and not common sense. The person you replied to might have known that their eBook reader is prone to failure but what about the vast majority of consumers?
When I was a kid, about 9 or 10, my mother taught me to type. As a teenager, she had gone to secretarial college and had become a legal secretary typing up documents for lawyers before getting married.

I learned on a manual typewriter. I was the weird kid who typed up school reports on a manual typewriter before computers were widespread.

Along with basic sewing, it's one of the most useful things my mother taught me. We should teach every schoolchild to touch type.
"I don't know of people in the UK "

Yup, my fault, not clear enough. I'm talking about the US more than the UK, although now that UK universities have essentially been told by the government to behave like businesses, with poor people already less likely to apply than the rich since fees went from zero to almost ten grand a year in the course of a decade, I expect the UK to catch up soon enough in terms of buying your way into a good university (there is indeed already rumbling about places going to foreign students who can be charged far more than home students, establishing the principle, so I expect that as soon as universities work out a way to let people buy their way in, they will).

Edit to answer this point below:
""Give up, no point working hard, you will never make anything of yourself, the game is rigged"?"

No. My alternative narrative is "know the game is rigged". If you're playing a rigged game, your chances are so much better if you realise this (hence my very first post here - the people who rig the game work hard to make the unlucky ones think it isn't rigged).

Ruby vs. the world
Perhaps you've heard people say "most small companies fail due to cashflow problems" - what that means is: A company can have a great half-finished project/lots of pre-orders/great sales leads/user growth and they can see a light at the end of the tunnel where they'll be profitable. But before they reach the light at the end of the tunnel they run out of cash to pay suppliers and salaries, then they're bankrupt.

Let's say a company plans to make their game in 1 year with 5 developers paid $60,000 each, so they raise $300,000. Every month of overrun costs them $25,000 in salaries, and if they don't have cash in the bank on pay day the employees don't get paid.

At Blizzard or Valve this wouldn't a problem, they've got oodles of cash in the bank. But the whole point of going to kickstarter is because you don't have oodles of cash in the bank.
Hushmail is encrypted, but not anonymous. As you say, your details are tied to hushmail when you pay for it. Your account and data are all tied together.

Hushmail complies with validly formed legal requests - to the extent of crafting a backdoored version of their Java software and pushing out to the target user.

Some regions have laws compelling people to make the plaintext available.

Hushmail is useful for secret communications but only if you understand the limits.

Secrecy, privacy, and anonymity are trivially easy to break completely and hard to get right.
Pretty cool.

I missed details on how the pairing works, for privacy reasons it seems desirable that the tags are locked to (preferably a set of) cell phones.

Some more information about the battery would be nice too, what counts as "usage" for the tag exactly, and do they expose any idea of the battery's state? It would be nice to know that a tag is nearing it's projected end-of-battery, I guess.

Also didn't much enjoy the example with tagging the wife's car. Bleh.
Maybe someone can make a similar update list, but for kickstarter electronics (how is that OUYA going?).
It's not fully anonymous. Say my friend gets some bitcoins completely anonymously by doing something illegal. And then sends them to me completely anonymously. And then I go and spend those same coins on something like web hosting which ends up having some link back to me, eg I accidentally log in to it without using Tor one time.

The police can then trace that hosting account back to me personally from my IP, and then ask me who sent those coins to me. Even if I refuse to tell them, they can still look at my various contacts/friends/family to see if any of them are likely to have committed the original crime, and investigate further.

You can even connect to the bitcoin network via Tor. The risk comes when you spend them. If there's any connection between you and the recipient of those coins, then you're potentially screwed.
Lets quickly add that all up. Roughly 24 million dollars in total have been raised for crowdfunded games (just the kickstarter projects mentioned in the article).

For how long have we been doing that? Is crowdfunding games a 2012 thing?
Interesting to note that two of the founders (Thibaud Elziere and Quentin Nickmans) seem to have raised €1.64 million for one of their other startup (TextMaster) 10 days ago from the same VC firm [1].

> I think that we agree on the bottom-line: UserContentSpamChecker has no need for a state and is just some kind of namespace.

I'm not sure that we do. I agree that the current implementation of `UserContentSpamChecker#is_spam?` doesn't need state, but I don't agree with your conclusion that this distinction should be made obvious to clients, who surely just care that they have a thing that will check for spam, to which they can pass content. They don't care if it's stateful or not, as long as it accepts strings and returns booleans. Why are we trying to tell them that this particular method is stateless?

After all, even that offers a false guarantee. In your implementation, `#is_spam?` is just another method on an object instance - in this case an instance of class Module, referred to by the global constant UserContentSpamChecker. I can happily use instance variables in such a method:

module Stateless
extend self
def no_state_here!
@thing ||= 0
@thing += 1
end
end

> Stateless.no_state_here!
=> 1
> Stateless.no_state_here!
=> 2
> Stateless.no_state_here!
=> 3

Your implementation resists future refactoring, forces clients to create a hard dependency on a global constant, and doesn't make the guarantee you intend it to convey. We agree that the current implementation doesn't need an object instance, but can you explain what is actually better about avoiding one? Ruby is an object-oriented language, after all; objects are its common currency. It's not like we're introducing the Strategy pattern for a four-line method, we're just using Ruby as she is wrote. :-)

p.s. sorry vidarh, I see you've covered some of this already - serves me right for half-composing a reply then wandering off...
A ‘Second Skin’ Military Fabric to Repel Chemical and Biological Agents
"I don't know of people in the UK that can get into universities with significantly lower grades, just because of their family."

But going to the right school makes it considerably easier to go to the right University in the UK and going to the right school really is very strongly tied to wealth and status of families.
There are two types of MBAs ... a) people who can already "get stuff done" and then went on to add an MBA to their credentials b) people that have no other skills and (IMHO), no underpinnings for their new business knowledge. I think the second type is typified by someone that goes to college in business for their undergrad degree and moves straight into the MBA program.

I don't know what the current climate is, but early in the last decade, MBAs were about half the salary of a good programmer. It was economical to hire one for about every 2-3 programmers just to offload some of their non-programming tasks (updating MS Project schedules, specifications, etc - and yes ... it was BDUF).
"And "arlskling" isn't a million miles away from "darling"."

It is, however, a million kilometers away. The "-ling" suffix here is from Old English, and was used in personal nouns. "Dēorling" is "dear-ling", or one who is dear. In modern English it's often used as a diminutive. (Eg, "duckling", "hireling".)

The "-ling" suffix also exists in other Germanic languages. For example, "Yuengling" is a brewing company in the US. Its name comes from "an Anglicized version of Jüngling, its founder's surname and the German term for 'young man'." (So says Wikipedia.)

The Swedish "älskling" comes from the verb "älska" (to love) and the same suffix. One page describes the suffix as "ordbildningsform som användes i fornsvenskan för att uttrycka litenhet", that is, a "word formation used in Old Swedish to express smallness", in other words: in the diminutive.

So while "darling" and "arlskling" end the same, it's because both language share a similar "-ling" mechanism.

The base word ("dar" and "älsk") have different background. The "dar" is from "dear", and the Swedish cognate for dear is "dry", which means "expensive" in modern Swedish. Consider "the price was too dear for me.")

That's why you shouldn't think of "älskling" and "darling" as being related words. They are as related as "yuengling" and "duckling", which isn't very.

Well, for a translation about finance it is (very!) surprising that it seems to have just transformed "kronor" (="crowns", the everyday name for the SEK, the Swedish currency) into "dollars". It's not as they two currencies are 1:1, or even close to it. Very strange.

Also there was a Swedish word that was just copied ("anullerades", meaning more or less "cancelled", "voided" or something along those lines) into the English text.

But, overall, it's still rather impressive.

I wonder why other USA-ians as a community/society seem to accept this kind of favoritism. As the author repeatedly notes, here in Western Europe this is unthinkable. Time and time I am confronted with the differences between USA and Western Europe, even though we seem so close culturally. I find it fascinating. Thanks for linking the article here on HackerNews.

Finally, there was the case of Becca Jannol, a girl from a very affluent Jewish family near Beverly Hills, who attended the same elite prep school as Julianna, but with her parents paying the full annual tuition. Despite her every possible advantage, including test-prep courses and retaking the exam, her SAT scores were some 240 points lower on the 1600 point scale, placing her toward the bottom of the Wesleyan range, while her application essay focused on the philosophical challenges she encountered when she was suspended for illegal drug use. But she was a great favorite of her prep school counselor, who was an old college friend of the Wesleyan admissions officer, and using his discretion, he stamped her “Admit.” Her dismal academic record then caused this initial decision to be overturned by a unanimous vote of the other members of the full admissions committee, but he refused to give up, and moved heaven and earth to gain her a spot, even offering to rescind the admissions of one or more already selected applicants to create a place for her. Eventually he got her shifted from the Reject category to wait-list status, after which he secretly moved her folder to the very top of the large waiting list pile.90

In the end “connections” triumphed, and she received admission to Wesleyan, although she turned it down in favor of an offer from more prestigious Cornell, which she had obtained through similar means. But at Cornell, she found herself “miserable,” hating the classes and saying she “didn’t see the usefulness of [her] being there.” However, her poor academic ability proved no hindrance, since the same administrator who had arranged her admission also wrangled her a quick entrance into a special “honors program” he personally ran, containing just 40 of the 3500 students in her year. This exempted her from all academic graduation requirements, apparently including classes or tests, thereby allowing her to spend her four college years mostly traveling around the world while working on a so-called “special project.” After graduation, she eventually took a job at her father’s successful law firm, thereby realizing her obvious potential as a member of America’s ruling Ivy League elite, or in her own words, as being one of “the best of the best.”91

One of the guys from Hello Games did an AMA on reddit a little while back (creators of Joe Danger) . While he didn’t give a dollar amount, he made it seem like it cost several hundred thousand to develop. For what it cost, I'd say those guys did an awesome job.
