> Does modern Racket have anything comparable to Clojure's collection primitives?

See: https://news.ycombinator.com/item?id=6300845

Also, yes, there are generic "sequence" operations which you can use to abstract away a type of a collection you use. There are lazy sequences too, although they are not the default. There is also a set of very powerful "for" forms, which are an alternative to recursion when traversing sequences (and can function as sequence comprehensions, too).

> and Scheme emphasizes simplicity of implementation. But it still bums me out.

There is a reason why Racket name was changed from PLT Scheme. Racket outgrow Scheme some time ago and continues to grow still. It is "Scheme with batteries included", which means it's not Scheme anymore. But it makes it a great language for practical applications. It's not that great for embedding, though, while normal Schemes are.

Anyway, I find Racket to be the most impressive language I've seen until now. It could use some more developers working on it, but that's all it needs to become on par with Clojure - or any other language for that matter. This makes it's design truly impressive, in my opinion at least.
SimCity on Mac is 'totally unplayable'
I am hardly a big fan of Khan Academy, but not only is there hardly any precise or logically sound criticism in this article, the video presented as exemplary is horrible, just unbelievingly dull, the level of enthusiasm is about that of a voice synthesizer. Together with the strange aversion of mathematics for the sake of supposed "pedagogy", I find it rather unconvincing, to put it mildly...

Your first paragraph may be right, but I think the rest is wrong.

Paper education materials have a recurring distribution cost, whereas digital materials have a larger up-front but mostly one-time cost. Investment in both digital education materials and widespread access to computers is what is revolutionary, not the specific lessons.

There is always some sort of blurb in an article like this that says something dismissive like "such a such a video which was proved bad by such and such people was switched out for a better one after the criticism". That's the point! One video file on some server somewhere is overwritten and everybody immediately has better materials than they did before. No new workbooks, no new editions of textbooks, no printing press or shipping involvement whatsoever, it's just fixed.

I'm sure a lot of these educators agree with that premise and would love to start a competing platform or work for Khan Academy itself on improving its material. Perhaps the real criticism is that Khan Academy is a major hype suck, making competitors hard to launch, and that it's apparent success has made it over-confident and closed to wider collaboration with educators.
I think the variance on sides is intentional, to balance traffic flow at gas stations.

(Imagine a gas station where most cars use the same entrance and have the tank on the same side. Half of the cars would need to do a U-Turn to use half of the tanks).
450 tons of water every day, for somewhere around 2 years? Is that still a drop?
Yup. Valgrind is the bees knees when it comes to debugging any C program. I do not remember if I used it or not for this particular purpose, but it definitely would have helped.

"User privacy should be of utmost importance for all GNU/Linux distros."

Why? It's a feature which takes a large amount of work to implement, has a series of poor tradeoffs, won't actually increase the size of the user base much, is incredibly hard to do well and is very hard to market to users. Not to mention the fact that a large number of GNU/Linux distros are aimed at markets where such user land improvements are largely immaterial (e.g. on servers).

The simple fact is that most users don't care about privacy in the same sense that DDG cares about privacy. If they did, then there would be a huge economic incentive for everyone to make these sorts of changes.

I mean, the numbers are regularly 3-10x off. With that kind of variance, maybe you can pull out some truth if you're the Compete whisperer, but to most people, it's worse than useless, because it can fool the unaware into thinking it means something. If it were at least mostly directionally accurate, that would be a different story, but as far as I can tell, it's mostly a random walk. Alexa is a bit better as far as I can tell, in that it at least conveys somewhat accurate vague trends, but it's still not very helpful. The only one that's worth a damn is Quantcast direct measurement, but then of course that's accurate, and it's opt-in. Comscore's methodology seems better than most, but I haven't compared with hard numbers.

It's especially annoying when people whose opinion of your site matters quotes Compete numbers and trends for your site to you as though they mean something.

There was a really good post that I can't find where Spolsky (I think) was writing incredulously about how Compete was telling him that Stack Overflow traffic had fallen over the past 6 months or so, when it was the opposite, to an extreme.

Seriously, worse than useless.

Some time ago I used it to quickly change my layout from qwerty to colemak, and often it couldn't keep up with my speed (and I'm an average typist: ca. 65 WPM), which resulted in wrong order of characters.

Remember this was written in the eighties, Norman's discourse on mental models was transformative not just within the field of IT, but the entire field of psychology. Before psychologists thought people used logic to make inferences about the world, but after Normans work it became apparent that people developed detailed mental models on how the world works.

Online terms - better with notice
Someone whose maths teaching videos aren't very popular complains that hers videos are better than the videos which are popular.

Khan academy isn't popular because he has money from Bill Gates, his videos were hugely popular on youtube long before that, for the simple reason that they satisfied user demand.

She needs to ask herself why there's more demand for people who want to learn about "mean, mode and median" than there is demand for learning about "levels of measurement and sampling methods". I'm guessing most kids and adults will never have to design randomized trials and data collection, but they will come across averages in every day life.

From her description she mentions how she spends a lot of time thinking about theory of teaching and rewriting and editing to correct mistake and edit out hesitations, what was noticeably missing was any discussion of applying user analytics, A/B testing, etc. to better understand how her users were interacting with her videos, when they were losing attention span, etc. One of the reason that Khan Academy is successful is they take a very metrics driven approach to iteration, something that should be very familiar to any startup founder.

Sure Khan's videos are flawed but people want to watch them. It doesn't matter how much better pedagogically Dr Nic's videos are if people don't want to watch them.

Ideally it would be someone who has had such set up from before the spike, so that there is a baseline for computing the increase.

Also, an arbitrary set of exit nodes is obviously not guaranteed to capture the spike. In fact there might be no spike at all in exit traffic (quote:) "So while there are a bunch of new Tor clients running, it would seem they're not doing much."

They also had the chance to undo mistakes and rebalance things from the original Netrunner.

The constant release of new data packs is eventually going to become really tough for new players. I hope they run some kind of restricted tournament format (e.g., only the core + most recent data pack cycle + most recent big box expansion) so that the keen newbie doesn't have so much of a buy-in, but they can grow into the open constructed format later.
I am completely puzzled too by this controversy. I did not see pg saying that people with heavy accents could not be funded. He just said that CEO has to be a good communicator and not having a heavy accent (compare late 1960s Schwarzenegger to one in 2000s to see how one can improve) is part of the deal.

There is nothing preventing people with heavy accents taking a technical co-founder role.

Anecdotal evidence: my father the technical co-founder of a products company has a rather heavy accent while his US born co-founder was the CEO. It worked out decently for them and very well for the company itself: company has been bought for the 2nd time, that is VCs sold it to a conglomerate.

I am really curious about what kind of internal turmoil is going on at the studio if an AAA title is shipped with this kind of quality despite numerous delays. Since they delayed it a few times, it's obvious that they KNEW the technical challenges and the issues it had, but somehow in the last minute the team went "Screw it, we'll do it live" and shoved it out of the door.

If brand new iMacs and Retina Macbooks are having problem with the game, it's obvious that the dev team just gave up towards the end (or were told to do so), since I doubt all of those problems escaped QA's attention.

This is EA and Maxis we are talking about here, not some indie studio being funded by Kickstarter. Either all of the competent staffs (QA, Eng, PMs) left one way or another or people just didn't give a fuck anymore in the end.

Considering the PR fiasco from the PC version earlier this year, this screw up is so atrocious that I'd more likely to believe they accidentally shipped the wrong build or something...
Lol on the edit :P
Satisfying short-term demand doesn't mean it's always the best option. For example, it might be in the best interest of a nation or people to plan for the long term and optimize for future demands.

Ask HN: How Can I leave Syria now and get asylum in Europe (Germany)
Guys,
I am in Syria(specifically in Damascus). Seems war is rolling out. Most of the people are moving to border regions but I cant and I am a programmer worked as a remote dev for an Australian startup. But I am not sure how long I will be able to work living in Syria. I want move to Europe specially in Germany as the startup scene is booming in Berlin. So can you guys give me suggestion of legal way to move in Germany as an asylum and will I be able to work if I can move. I went through google but couldn't find much information. And I will be happy to have contact with startups that are hiring dev. I have couple of years backend development experience with Python(Django),LAMP,Node.js and some unix skill. Thanks in advance.

Ask HN: How would you handle a potentially #1 mobile game?
FIRSTLY: Yes, this could all be hot air, know-nothing ideas-guy type drivel that we've all seen before, but I'm asking you to make an assumption this is accurate and this potential does exist. I can easily find a hundred people to tell me that it's probably not all that and I should just do it & figure it out later, but that's not what I'm after here. Think of it as a thought exercise if you prefer.

Now...

I'm working on a mobile game that I truly believe has the potential to hit the top of the app store charts. It's a fun idea I've had for many years. I wanted to build it for the Amiga many years ago but lacked the skills but it's absolutely perfect for mobile devices - it's one of those things where it seems the stars have just aligned. It has somewhat unique gameplay and there is currently nothing like it available.

However, I've never done anything like this before and I'm broke. Absolutely flat broke. I have no money to market this whatsoever at the moment. So I'm wondering what the path would be for someone in my position. Publisher? Submit & hope for the best?

Main worries:

* Due to lack of funds to promote, it languishes forgotten in the depths of the app store and no one ever sees it.

* Clones. Someone or someones see it, see the potential and knock up a clone, with marketing behind it and rake in the readies

I'm aware of the execution-is-everything mantra but this is a self-developed game. I just don't have the resources to compete with studios out of the gate so I need a bit of help to avoid screwing myself up before I even begin.

So, TL;DR, if you had a really great mobile game ready to go, what would you do to maximise its potential?

Thanks in advance!
Fair enough to assume this will only be a local network? You need to be a registered Operator in order to have roaming agreements for connectivity to other networks.

Additionally if they are using SIM cards issued by another operator that attaches to this network it will have to remain local as the global title routing would route back to the home network's HLR that the subscriber belongs to during the location update procedure.

(This post isn't intended to be personal so I hope I don't cause any offence).

I often see people talking about how great they personally found a MOOC course, but that self-assessment is largely useless. To put it bluntly: you don't know what aspects of a topic you don't understand, were not told about, or whether the information you received was at all accurate, because you lack the expertise to determine that.

For example, people thought they had learned a lot from the Udacity Statistics 101 course and it received glowing reviews from participants. But unfortunately they did not learn about some of the most important basic ideas in statistics, and some of the things they did learn were just wrong:

http://www.angrymath.com/2012/09/udacity-statistics-101.html

the course is amazingly, shockingly awful. It is poorly structured; it evidences an almost complete lack of planning for the lectures; it routinely fails to properly define or use standard terms or notation; it necessitates occasional massive gaps where “magic” happens; and it results in nonstandard computations that would not be accepted in normal statistical work.

Astoundingly, the Udacity Introduction to Statistics course manages to go almost its entire length without ever mentioning or making any distinction between the population and sample in a study. I say I'm “astounded” because in my classes (and any one I've surveyed or looked at), this is the key idea in introductory inferential statistics. It's the very first thing that is mentioned in my class (or the book), and it's the very last thing on the last day, too. It's the entire reason why inferential statistics is necessary in the first place. In fact, the very word “statistics” means measures for one (sample) and not the other (population) – but you'll never learn that from this class.

Im all for blogpost that start a discussion about improving some parts of Khan Academy, but the tone in this blogpost kind of bothers me.

And? This also applies to to normal educational environments, not just MOOCS. Why do people assume that courses delivered on premises by an average teacher is going to be better than a MOOC delivered by world class guy. I'd wager that on average on premises course has more gaps/problems/mistakes than a MOOC. These on-premise courses will never be exposed to criticism, mistakes never seen. Moocs are exposed to every educational 'expert' there is, so lots of criticism pops up. That's a good thing. Normal courses don't have so many 'experts' looking at them.
