>As far as I can see, nobody has come up with a magical metric for rating teachers. If anything, most of the metrics out there are outright counterproductive -- and you can see it in schools across America, where teachers are being constantly urged to inflate grades for their 'customers', overlook plagiarism, ignore the most talented students in favor of the least talented ones, and help drive down the quality of education for the next generation.

You can do things to improve the quality of data - use multiple metrics, don't announce them up front and certainly don't standardize - so that optimizing for a specific test doesn't justify the cost, also change testing as needed/with dynamic feedback and use the results to get insight in to the problem. Computers can only help with this sort of thing. Ultimately it's about defining the objective of education, what environment students are supposed to be prepared by it and exposing them to that environment, just like you want to test the system in production as soon as you can, benchmarks are always synthetic and can't replace "real world" testing.

Data won't capture everything and could in fact be 100% misleading - that's the nature of imperfect knowledge - but if used correctly it can help provide insight in to situation. Just don't conflate benchmarks and reality, use it as a tool for improved feedback/analysis. Of course this approach is absolutely incompatible with bureaucratic systems. Heck the entire education system is based around optimizing for arbitrary/artificial evaluation metrics (all that crap about higher education and signaling, that starts with primary education).

As for favoring least talented over most talented, that's just different objectives, I don't think it changes with more quantifiable information about students performance, do you want to raise the bottom at the expense of the top.
Sometimes it demonstrates that a person is just trying to soften the blow from a rude or insulting statement, but at other times it demonstrates that they hold a complex view which is most clearly explained by describing its limits or contrasting it to other views.

It is mentioned as the 6th definition of "hacker" in the original jargon file [1], so at least by 1988.

surely apathy would result in nobody being elected?
I don't see anything wrong with this. There are a lot of posts on HN are looking for feedback, and criticism can very easily be mistaken for aggressiveness. Sure rudeness is rudeness but prepending "I don't mean to be..." in front of your sentences don't make it so.
I used to start sentences with "No offense, but..." when I felt I was going to say something controversial until a coworker pointed out that the only reason what I was saying was controversial was because I prefaced it with "No offense, but...".

So now I don't say that anymore. I just say what I mean and people aren't as likely to be offended.

The movies "Hackers" and "The Net" were released in 1995. "Hackers" used the term to mean "someone who penetrates computer security". The one use of the term in in "The Net" [1] was ambiguous as to whether it meant this sense, or Paul Graham's sense of the word[2]; but 90% of the movie was about security and counter-security. So I'd say that the [counter]security connotation was common usage by that time.

Gosh, this is a terrific resource. It's almost as much fun as Google's Usenet archive, back when it actually used to work.
Why do you have to assume that? Can't it just be that PG was talking to someone, this came up, he wondered what the results would be, did the search, and thought it was interesting enough to share? You know, like any hacker probably would?
Hardly. Strongly disagree if that is the vibe you took from the article.

It just reinforces the:

"tough guys win, nice guys lose" mentality. (Albeit, the original poster didn't exactly lose).

People who try and juggernaut their way often possess traits which might allow them to steamroll through certain personalities. This BS pitch clearly didn't work on the OP, and at that point, that was all it was a BS pitch. But it clearly worked on other people.

I think parent means what the characters in the games are supposed to be. I don't think the vast majority of players see others as "enemies", they're simply adversaries, much like in a sports game.

There's the random oddball (usually an immature kid) that gets too worked up when he loses and starts insulting people, but then again, that's common in sports too.
That is the way it is supposed to work but how many people would say politicians are doing what their constituents really want.
I think the point is that while a sociopath might be more likely to volunteer for it, volunteering for it doesn't make one a sociopath.
I'd like to know what "key NASA computers" means. This could mean a computer that can send commands to sattelites and rockets, or it could just mean a central e-mail or file server used by office workers.

This is exactly why I stopped writing reviews on IMDB once they commercialized it, and why I once wrote reviews for Amazon until I thought better of it.

Core and Supplement - a proposal for large scale reproduction
The development of autonomous systems are inevitable, I would like to propose a system for regulating their reproduction.

I am aware that it may already exist.

The start of the population is labeled as the core population, staying a constant number unless the distribution of the core is not consistent enough to reach the rest of the population.

Members of the population undergo continuous hash checks with encountered core members to verify that their own is correct. If a large percentage of incoming hash sources note that their hashes are not identical, that unit would pass a production signal to the nearest verified core member which is to continually prognate (other core members follow same terms) the signal until an appropriate finish signal is received, along with the hashtag of the confirming member.

For additional redundancy, verification of a hash tag would append the unit's identifier to the end each time any has is verified, so that orders could be checked by external sources for potential errors.

Members of the core would require more overall processing power than other members of the population would be required to achive.

If it is required to produce a large quantity of units without the overhead of core members, members labeled "else" could be produced without the constraints of a core drone, however, the population is meant to stop reproducing after a certain threshold is reached.

To continue reproducing, a variable percentage of the population would be selected and have their code verified by core members, they would be labeled sub-core, following only the verification/termination orders of the original core group. Once a member of the population is to be cleared by the sub-core, another group is produced.

you just reminded me of one of those confusing stories from Godel Esher Bach.
I think your analysis is too glib here. [And since PG seems to be implying the same thing, that goes for him too.]

It’s typically a way of expressing anger/displeasure/etc. without turning the comment into a personal insult. If I say “I don’t mean to be rude, but you made a grammatical mistake”, or “I don’t mean to be harsh, but your idea doesn’t make sense” what I mean in the former case is something like “anyone could make that mistake, please don’t take it personally, but I figured you’d like to know”, or in the latter case, “you need to clarify your idea, because you’re losing your audience; I don’t want to imply it doesn’t have any merit, but as currently explained the merit doesn’t shine through”.

Being able to make quick softening caveats without taking up a paragraph is very useful, and our language is more nuanced and powerful for having these constructions.

Etymologically the word obvious comes from ob + via, in other words something blocking the path (to understanding). But in modern usage it's of course used to mean the opposite, something that's trivially easy to see. Though ironically most propositions prefaced by 'obviously' are anything but.

Anyway, if no such word exists, I'd propose propose calling them obvianyms, after what is perhaps the best-known example of the phenomenon. Plus, the fact that the term is actually an anti-cognate adds a third layer of irony, which is kind of cool in and of itself.
And 5.56 won't help you if an enemy has a tank. What's your point?

My point? To paraphrase Han Solo: "Hokey religions and hand-to-hand are no match for a good blaster at your side ..."

Well, not quite. But that was too fun not to use.

The argument was that as someone trained in martial has significantly better chance than someone that isn't.

Depends on your definition of 'trained': attitude is everything.

A guy can be a trained martial artist, kick-ass in tournaments and still loose big in a fight because - away from the mat - he utterly lacks the will to fight.

My point - I guess this goes back to Mr. Solo - is that martial arts are great and all but it's way to easy to fool yourself that you're capable of kicking ass, but you're not.

Especially if you're facing off against a guy with a gun.

Which are pretty much available to anyone in the US, where I live.

Lytro Light Field Camera: Focus on the Future
I'm more in agreement with angersock on the topic of the draft.

I would love to live in an enlightened world where we can all talk out our issues, without ever resorting to violence. I do believe that people, on an individual level, can be reasonable.

The problem <i>is</i> the masses. If a leader comes out with a compelling argument casting group X (country, terrorist cell, religious belief, etc) as a direct threat to the social group YOU belong to, you probably won't want to be the one who stands up and says "maybe that guys full of it?". You look weak and you look like you don't want to be part of the group. And the leader will tell you as much and try to push you out of the group.

Now, spin that story where there's a universal draft. All of a sudden, you and everyone else in the social group have to weigh the consequences of you or someone you love dying somewhere far away. When someone pipes up and tells the leader he/she's full of it, they don't sound like such a nay sayer.

In regards to just 'laying down and letting the terrorists kill you', I don't believe angersock meant that at all (correct me if I'm wrong) - we should avoid all this security theater BS. Do you really think that body scanners at airports are stopping terrorists? Any time I've flown into the states it seems like there's as many TSA agents as there are passengers.
Nice! This looks to fill a role that's quite challenging at scale using MySQL, SOLR, redis, etc. I've forced sphinx to fill this role but the limitations of real-time updates (no infix/suffix support) make deployment awkward.

My two immediate questions are ballpark memory usage and if Cleo supports any form of persistence. I don't find mention of either in the docs, and only spammers have found the Google Group so far. Time to fire up a test instance.

It's far too common for online "magazines" to simply try to copy its dead-tree counterpart. PDF files, or even the concept of discrete, non-interactive, view-only pages, traditional print dimensions and layouts...

The browser, tablet, and mobile as a medium can out-magazine traditional print, I don't get why everyone is still satisfied with just cloning all of the properties of print magazines into the digital world.

Making a SO competitor is not the only reason to download the data, just as making a Wikipedia competitor is not the only reason to download Wikipedia data.

One very important reason for downloading the data is for simple archiving. If Wikipedia or SO disappear tomorrow, their data will still be in the hands of the public, ready to rise like a phoenix from the ashes. Not so with proprietary, closed data that's never released to the public.

Another important reason to download the data is to use it locally and with your own tools. Plenty of people download Wikipedia data for offline browsing. I'm sure the same could be done, at least in theory, with SO data.

Yet another reason is to mine the data in ways that the parent website might not allow (due to lack of knowledge, lack of interest, or lack of manpower).

That problem is not specific to SSL client certs. It potentially affects every authentication mechanism (on the same computer). Typing in your passwords? Keylogger. Using a password manager? Stolen passwords. The password database is encrypted and you have to type in a password to decrypt it? Keylogger.

If your system is rooted / infected with malware, you lost. The only solution is to format the drive and start over.

The alternative is to use a 2 factor authentication mechanism that uses a separate device, like your phone receiving a text message. That's a pain for the average user, and certainly not "simpler".

My problem with this softening caveat is that the speaker acknowledges that he will present his argument in a way that will offend/sound rude/make him look like a jerk. Instead of priming my listener for thinking I'm rude/a jerk/etc. through admitting that I am, I'll just think of another way to gently criticize. Playing to one's emotions is all about being convincing, and "I don't mean to be..." is an unconvincing phrase.

I'm not really sure what you mean by that - Zepto is a DOM editor and Backbone provides an MVC structure which represents the logical state of the UI. Higher-level organization in a Backbone app is accomplished by view composition.

If, however, you are referring to the weak link between Zepto-managed DOM and Backbone Views via hand-rolled render functions, then check out outback.js, a declarative data binding layer for Backbone in the same spirit as Knockout.js - well, more than spirit, the binding extensibility layer uses roughly the same API and much of the same documentation.

The number you're aiming for is going to meaningfully change how you act. For example, you might get an offer for $50 million. If you do, the probability of making it to $1 billion matters. (Incidentally, the creator of this community was faced with almost exactly this choice.)

It may be true that the number of $1 billion exits per year is only, say, 10 times fewer than the number of $50 million exits. It's an empirical question. The numbers matter.

Let's just raise the $1 billion number until it's a better bet to go for $50 million. At some point the argument that "both are just absurdly big numbers" breaks down.

Perhaps the reason people think that the numbers don't matter is because they believe that the skills required to build a $50 million company is no different than those required to build a $1 billion (or $100 billion) company. That I buy.
I ran two-hour workshops for designers in 2010. Fifteen in all, free to attend, with about 50% non-designer attendance.

Workshops are a lot of work -- I'd spend 8-16 hours prepping for a two-hour one -- but they're one of the most asked-for types of local events in Austin:

Presentations by my peers	95	92%
Panel discussions by my peers	74	72%
Hands-on workshops	73	71%
Presentations by companies	60	58%
"Field trips" to related industries	57	55%
Happy hours	51	50%
Social/networking lunches	42	41%
Panel discussions by companies	42	41%
Other	2	2%

I'm happy to answer questions based on the workshops I held, you can reply to this or email me (contact information in my profile).
I'm reminded of Danny Hillis' description of telling Richard Feynman his idea for the connection machine:

One day when I was having lunch with Richard Feynman, I mentioned to him that I was planning to start a company to build a parallel computer with a million processors. His reaction was unequivocal, "That is positively the dopiest idea I ever heard." For Richard a crazy idea was an opportunity to either prove it wrong or prove it right. Either way, he was interested. By the end of lunch he had agreed to spend the summer working at the company.
This is the point, though.

I agree that the layman's interpretation of "created or supported" isn't necessarily the same as the formal definition of the terms by the US govt, but criticizing Apple for using the formal definition isn't reasonable.

The intent of the formal definition is to answer the question "what would be the impact on US employment if this business were to cease operation tomorrow?", and I believe that Apple has made an honest effort to compute that number, probably rather conservatively.

Perhaps you disagree, but you seem to be arguing against semantic interpretation of the terminology, instead of being skeptical of the results.

In response to your point about how to present this data to congresspeople, I'd argue that while there are some legitimate economic dunces in elected office, there are few that don't comprehend the cascade effect of business activity and therefore employment. Furthermore, I doubt that any congressperson would consider Apple's use of "create or support" to be misleading, because it is absolutely the standard usage of the term in these sorts of assessments. That does not, of course, mean that some senator who smells television coverage won't take notice of the confusion and grandstand his or her condescension for his or her electorate. It might even be a successful strategy, but we don't have to help.

Obviously I haven't audited the numbers. That's a valid line of inquiry, but history shows Apple to be fastidiously circumspect in such matters. There's a new sheriff in town in Cupertino, but if anything he seems to be even more careful.

I wish my ex would talk to you. I think most issues that couples have is really on communication, and a lot of time we misunderstand each other. We fail to look at our partner from his/her perspective. I broke up with my ex because he failed to see my point of view and lacked generosity on understanding how I feel. I find that most guys in tech fail to express feelings and emotions when they're in relationships and fail to see things from their partners' point of view. What girl would want to date someone who's only into himself?

I think someone like you would help guys become more self-aware on what their actions have on their partners, and help them be more considerate. This is not about becoming someone you're not, but being more open and considerate about what their girlfriends when in relationship. Trust me, women don't need that much time, but how you can communicate that to us matters more.
well, the effect seems real enough, looking to other references;

You are assuming an awful lot about me based on a few words and also have a very limited view of the martial arts. Some martial arts are for show, some are for fitness, some are for sport, and some are for inflicting the most damage in as little time as possible. What you end up learning has more to do with the philosophy of the instructor and studio than the style you chose to study. My instructor is also a combat veteran. I study american kenpo under him. The system is one of the more violent martial arts. TDK has the reputation of being the McDonalds of the martial arts, belt factories where you just show up once a week, pay your dues, and walk out with a black belt after a year and a half. Even still, I am sure there the some hardcore TDK studios out there.

As for martial arts not being taught to soldiers, what do you call Krav?
