TL;DR I am currently taking an adult who "can't math" through Khan Academy from K-2nd on up and she's "mathing" wonderfully now that we're comprehensively filling in the understanding gaps. Too bad she still doesn't like it. :P

I know someone in that class of people that "can't math". Initially I tutored her in algebra and she did alright when we were working together, but as soon as I turned her loose or she went in to take a test she couldn't remember or apply the techniques. She was allowed to go into Pre-calculus (she wants to be a Chem Major). But without extensive help on each section she would fail spectacularly. And after a while it became obvious why. She could think logically and when explained clearly or relating to other concepts she's recently learned it all made sense, but she had so many deficiencies in basic math that nothing past that would really stick. As an example I taught her the formula for computing the area of a square multiple times, but she would swear this was the first time each time because there was no foundation to hang that new knowledge on.

Now I but I have her working through Khan Academy from the ground up (K-2nd) and now that she's up to 5th grade and I've explained how basic concepts relate together, like multiplication and area or fractions and division she's actually starting to "get it".

She just lost the thread of "mathing" around 3rd grade and never found it again. Now that she can go through it at her pace and has someone that can patiently explain it from multiple angles it makes sense and she's doing things on her own that I was afraid she's never "get".

That said without Khan academy and a detailed list of sub-topics in math (45 individual skills for dealing with fractions for example) I'd have never been able to cover all the small things that add up to a detailed understanding of arithmetic. I'd have covered fractions from maybe a handful of angles and called it good knowing that it wasn't enough practice without having an answer for how to practice more without stupid rote repetition of the same kinds of problem.

This is the best gist management tool I've ever seen, and AFAIK the only one with a `gist edit` that lets you quickly edit your gists directly from your command line.
Thinking about this even more, the company is only cash flow positive because they are not paying you. And if they are not paying you, the question begs who else are they not paying.

Just because the CEO has sold multiple companies and realized profits for previous investors, does not automatically make this a golden egg as well.

Finally, just because the CEO says you are at the top of the stack and future funding will not dilute you, does not mean it will not happen. In fact it is fairly certain to happen if additional, bigger investors come on board. If you want to get an idea of the dilution, Google an Excel cap table example (there's actually a pretty good one on http://cooleygo.com) and play with the numbers a bit.

I would honestly skip the whole deal, push for either them to pay you what you are owed to date or go with a convertible note. I would also talk to an attorney before I made any decision. It just seems to me that the CEO is trying to make it sound like a great deal with no risk, when in essence the risk is enormous.
Netflix employs many smarter business people than me that operate with a lot more information, so my opinion may be completely incorrect, but I've always thought that they erred by being scared off of the criticism they got when they increased their pricing a tiny bit. Less than ten dollars a month is an incredible bargain for the vast number of hours of content that they provide. Netflix should double, triple, or quadruple their price and get themselves in financial position to meet the demands of all of the studios going forward for all of their content.

You can't do that if you're pricing yourself out of that game though. I want to pay Netflix more money for a catalog that has virtually every movie/tv show ever. But that's just me.
Yup. This is why we moved away. When you go to an open house and every single person there except you is speaking only Mandarin, including the agents, then you know your time is done.
>Science doesn't give a shit about your expectations.

Language.

Also, I didn't say it's about "MY" expectations. It's about what the expected distribution is, which is the whole context that makes something big or small.

"Expectations" are entirely irrelevant to whether a number is big or little.

Actually, it's all about that. Bringing 10,000 times 6 by throwing dice 20,000 times is too big, because the expected outcome is about 1/6 throws to be 6.
Netflix needs to release batches of episodes every Friday. Over the course of a weekend people can watch 4 episodes and then chat about them on Monday. A little space and anticipation is a good thing.
I think that's a side-effect from allowing control of our industry messaging board to rest in the hands of YC instead of the community. I've actually hoped that the balance would swing back to /r/programming where moderation is done by the community. Also the revenue to keep the site running would be generated by neutral-ish advertising instead of YC gaining value by being able to push their own startups.

I suppose that this is a strange thing to say, as I work at a YC company which takes advantage of those connections... In fact we maybe draw on it too much (I do work at Clever, sorry if our posts bothered you!).

Overall, I think YC are pretty benign overlords, and they have an incentive to not rock the boat. YMMV though :)
No, that's actually the bread and butter of intelligence work. At least it was in HUMINT, if not in SIGINT. You identify individual(s) with access to what you need and then work on/with them. This is not surprising or even controversial (mind you, I am not in any way in favour of such things, just playing the devil's advocate a bit) at all. Hard evidence of dragnet, massive, all encompassing surveillance really is the new revelation that has come out of Snowden leaks including this one. Targeting of individuals (especially if they're foreigners) was always going on.
No temperature is "dangerously cold" on a playground with proper adult supervision. -20C is really really cold, yes, and dangerously so if you're lost in the middle of the night somewhere with no phone or shelter, but in the middle of the day, in a school, where you can go back inside at any time? Not really.
Last Week Tonight with John Oliver is the new show to watch on the comedy side now with Jon Stewart stepping out.

HBO allows some of the best in the business work together and do amazing things, Curb Your Enthusiasm could have only happened on HBO and it is probably the best comedy show ever.

HBO is the only reason left other than live sports to have TV.

Part of the reason HBO is so good is lots of the original content is produced like a movie or like a full binge season as Netflix is doing. Because both don't have to chop things up and change or only write a few episodes out to get ad revenue, better quality content is produced. The networks that aren't writing in movie style or full season binge mode will miss out on this quality aspect.

A decent amount of people wear rolexes which are > $5000. You probably just don't notice them because they are fairly understated.

I'd also imagine guns for drug dealers have a more practical use case than conspicuous consumption.
Sure, where and how you draw those lines can be interesting, and possibly meaningful. I merely meant to raise awareness that you might have been addressing something the parent had not meant to say.
Understanding the English-speaking world's most famous poet and playwriter might be beyond the abilities of some people, that is for sure. It doesn't mean, though, that the language used is deliberately obscure.

I would estimate that most high school graduates in the UK could correctly parse the passage posted, given enough time.

Those with education specifically in English would parse it at first pass.

As someone who works at a Sapient-like organization, this idea is very compelling. I'd be awfully concerned about the total lack of structure though. As much as clients don't want to pay for a PM, they are there to manage scope and timelines. I've seen PM-less projects meander towards a death spiral where everyone is working and nothing gets delivered. You'd need a special breed of developers who are not only good coders, but know how to manage projects and deal with people. A lot of good developers suck at those.

Don't you require some sort of "trusted" status to post a job? I think that level of trust would mean the same accounts should be able to moderate their own postings.
There is discussion about all this buried in PG's submissions history - I found where points and submitters stopped being shown on jobs 1380 days ago, I think it was all part of the same overhaul:

Might be time to revisit it but I think presenting them as HN content is wrong - they're not HN content, they don't get to the front page because they're good or because one of our peers thought the rest of us might like it and more of our peers agreed.
I agree HBO quality is somehow better even though Netflix is paying top dollar. For example, Marco Polo is more expensive than Game of Thrones but much less entertaining.
Right. The name comes from precisely that.
You don't know what a CDN is, do you?
Google, whose core business model fundamentally depends on extensive data-mining of user information?

Does it? Try Googling from an incognito window on your neighbour's wifi. Use a live distro if you want to be completely sure. Are the results significantly different? Are ads any worse?

I have tried a couple of tests like that (on other people's devices, etc) and the only noticeable use of that trove of data Google has about me is suggested searches from my search history. Google Now can also pull an article of interest every once in a while the same way.

That doesn't mean they don't have the data and won't cough it up on government's request but there seems to be very little effective mining going on.
I don't see a future for proprietary platforms. Not too long ago, the music industry tried that. They were not successful, services like iTunes or Spotify won the customers.

It seems to me that the TV content owners have to make that same mistake, then there will be streaming providers that have "everything". Perhaps not Netflix, but something similar.
The last point that should be made:

Even if you follow all of the above, there is a 90% probability you will still fail. Startup success is still largely dictated by luck.
> Low availability of drugs.

You been to Roppongi recently? Drugs are being pushed everywhere by specific demographics (non Japanese working for the Yakuza).

> Police culture. The police only move forward with an investigation if there is enough to go on, leading to a high conviction rate.

Do you have a reference ? I suspect that's an incorrect statement. They have a high conviction rate due to putting people under duress. [1][2][3][4][5]

Yeah, this is pretty much the behavior that I want to see from open source maintainers: make decisions and build conventions but be open to having your mind convinced of alternatives.
There's a progression from ignore mobile => make it work on mobile => responsive design => adaptive design => mobile first. But that's not far enough. Native mobile apps are mobile only, so in order for web apps to compete head-to-head, they need to be mobile only too. That's a cultural leap the web needs to make. "The web has failed to beat mobile because it lacks 60 fps" seems premature until we finally figure that out. I'm not saying all webapps should be mobile-only, just ones that truly want to compete with native apps.
Spot on. Other responses are naive. They speak of "the banks". There are two entities here:
1. companies
2. individuals working for companies who get commission for selling loans whether they get paid or not

Plus there are many many other problems with banking other than sub-prime which boil down to the above.

That's why we need to start putting individuals in jail.

What is "insultingly lowball?" Were I a YC company I'd definitely leverage its reputation in targeting a certain group of eager, young, and naive labor. I'd view it much like I'd view the labor market in the video game industry: there may be an overall shortage of tech talent, but in specific cases there is an abundance of labor that can be had (relatively) cheaply.
So i've been running a private job board with 3k members for few years now. People can comment on job posts.

There are 4 kinds of comments:

* Mention of someone, to make him/her aware that job may interest him/her

* Correct the person who posted on the job on a typo

* Mocking the job. Often a big circle jerk we have to moderate

* Someone saying that the company is awesome they have worked there or know the founders, ...

I find it quite interesting however, it's never really bringing anything valuable to the job post. The comments are never about asking what are the use of X language, how are the teams, ....
So what? Of course China's capital outflows were huge in 2014 - so was its current account surplus. When China takes in huge amounts of foreign currency for its exports it must recycle those funds - which flow out of the country - particularly if it insists on intervening in the value of its currency (keeping it from increasing and therefore subsidizing exports). So, huge capital outflows for China doesn't necessarily mean a China-driven housing or asset bubble. It does mean the European Central Bank and Federal Reserve should have no problem continuing to sell paper.

Not using external service for font anymore because it's blocking. That means your time to first render is directly impacted by the time your user download fonts from a third party.

And have you ever landed on a site fully rendered but can't see the text? High chances that it's a third party font that can't be downloaded for whatever reason.
Is this only a font problem? Many sites serve jQuery and other files from Googles CDN. Aren't these the same problem? Also there are other widely used CDNs that could affect your privacy .... will this not get very far, when you want to avoid any of these??
Hacker News job postings are a part of the YC package, allowing users to comment could lower its value. We're a cynical bunch.

I think there is also an element of how we watch movie scenes today, compared with how it was done in the past.

For instance, if you want to see the ending of Terminator with the stop-motion animation, today you'd just go to youtube and watch it: https://www.youtube.com/watch?v=2KeniFoiT-0

It looks pretty decent, but that's not really terrifying anymore like people remember it.

In the past though, if you wanted to see that scene, you probably sat through the entire movie. When you do that, I think the effects in that scene work much better. That is because the rest of the movie was conditioning you, getting you excited. Setting the stage for how things in that universe work and look. Seen within the full context of their movies, old special effects hold up much better IMHO.

Another movie where I think this is in strong effect is the original Robocop. ED-209 in the boardroom is much more effective after sitting through the opening of the film.
Pretty spot on. And the "2-speed" union has been in the talks quite a few times in the past decade. I don't think we need more nationalism at the European level to strengthen the public opinion of the need for further integration.

It just seems that the news outlet have not moved out of the national border and are indirectly responsible for this feeling of being a national from the country before being European. That being said, a lot of people in the younger generation seems to feel European t least on an equal part with the feeling of being a national citizen from their country.

1. The problem wasn't in creating the shape we wanted - that's easy with CNC. The problem was creating the cross mounting post for Cherry. The process that ended up working was somewhat as you suggested: we basically used a lathe to remove material from a standard key cap until just the post was left and then we attached the post with a good adhesive to our custom key caps. The problem with this process is that it is very expensive in terms of labor/time and requires a high degree of precision to ensure uniformity. I think I might eventually make a keyboard using Cherry MX switches using this process, but for the current project the goal is to produce at least 100 keyboards while keeping the cost down. We tried for several months to make the Cherry MX Red work, but ended up deciding Matias was the better option in this case.

2. Modding key switches works well for a single keyboard, but really causes costs to soar if used in production. This wouldn't work for us because one of the main design points of the keyboard we're working on is making it financially accessible to a wide range of people.

4. This is a fair point. Honestly, I'm not too deep into the mechanical keyboard world beyond this one project, so I don't have a good feeling for other people's use cases. My hope, though, is that people do some really strange things with these switches and start innovating in ways I wouldn't have thought of.

Thanks for all your feedback - it's been really helpful. I haven't yet updated the campaign page to reflect it all, but I will soon.
I buy schwab and vanguard ETF equivalents of their mutual funds, and I get charged no commission when buying and selling them directly from them.

So where do they generate commissions as a company, compared to a person buying & selling their ETFs with a 3rd party exchange?
> I'm guessing they are downloaded again which is unfortunate..

Which is exactly the reason to use a web font CDN like Google Fonts. I have Open Sans on my computer, and I'll redownload it again in a year when the cache expires. If each Wordpress blog started including their own copy, I'd have to redownload it each time.
This seems like it might be useful in defending against acoustic side-channel attacks.
To Shill a Mockingbird: How a manuscript discovery became Harper Lee’s new novel
I would say "partly" rather than "largely". I think the reason luck seems to be such a significant factor is that everything else that depends on your idea, execution, networking, and so on are all tough, and exceptionally so en masse.

So, to minimise the impact of luck, you'd need to hit home runs in every other aspect which is unlikely. If your idea is great, but the rest so-so, then luck might seem like a stronger factor, and that's the sort of situation most of us would be in.
It's a pity that there isn't currently a way to leverage cached resources with different URLs for the same content.

In fact this would not be hard: if you could indicate, with the resource URL, the hash of the resource content, the browser could just use the resource with that hash if it has it in cache (no matter from which URL), and otherwise retrieve it, check the hash, and add it to the cache.

And now we get into a discussion about what constitutes public vs private API. I completely accept that the naked variable thing wasn't intended behaviour of Coffeescript. Nevertheless, it was a thing that worked and was widely enough used for it to be mentioned in the changelog.

So, thanks for mentioning it the changelog! It's great that you're aware not only of how your code is intended to be used, but how it is being used in the wild. That's a really good thing and worthy of praise.

The bit that annoyed me was that you knew this, but still chose not to bump the major.

I read your stance on semver the last time we all did this collective dance. Most of it makes perfect sense. It is a valid argument, and I would be very happy for us, as a community, to work towards something better than semver.

That has to happen in a holistic way, though. Our package manager uses semver. Publishing your package on that package manager is an implicit acceptance of that convention. The fact that someone can `npm install coffee-script` leads them to believe that it will at least attempt to follow the rules and conventions of that ecosystem.

(Incidentally, I only found out about the recent underscore-semver-round-2 1.8.0 thing _after_ publishing this post. This isn't a guy trying to stir up larger drama. This is just a guy who had to spend his Friday evening fixing a preventable bug in production and it made him grumpy.)
