Well to be honest, I'm not that far along into probably some of those same books myself, and I still get derailed by random curiosities and end up on Wikipedia or ordering a new book. The latest was a tangent into filter theory and digital signal processing, for a real-time audio project. It's hard to anticipate everything I should be able to do but I have some idea of the general order of things to study personally. If I needed to go in depth about Linear Algebra (and I definitely do), first I'd recall whatever I know about vectors and vector spaces, transformations and matrices and systems of equations, and start gathering articles and seeing if I'm missing any critical linked topics. After I get confident enough, I'd probably skip right to some textbook topic that caught my attention, say normed vector spaces, and try to make do with backward-skipping as a last resort.

Of course, that's just an artificial way of making the problem harder, basically, so that it's more interesting than safer but repetitive sets of exercises. The best way to be interested, by far, is to actually want to solve some problem. For now, anyway, I heartily recommend looking for problems that these disciplines can solve, and choosing one to solve yourself.

This doesn't work. I get "The content does not seem to be working." when trying to load the stream.
When Craigslist Blocks Innovations
of course really good/valuable domains will always be worth a lot more than the registration fee.

$25 is still basically nothing. Name one other thing important to you that you spend less than $25 PER YEAR on. Geez, right now I spend more on coffee in 1/2 a week than on a domain name. I spend more on toothpaste than a domain name. Who could possibly claim that is too high?

Squatters of course think it is too high. Owning thousands of domains they consider worthless. Well other people don't consider those names to be worth less than $25.. so if you do, maybe you shouldn't have them registered.
We could add 'whining about downvotes' to the list of things that are irritating about this sites community.

Since you're attempting to accuse me of something I didn't do, I didn't downvote anyone, I commented.

Stop whining.
I honestly don't understand a lot of the comments in here. For starters, many websites (eg Twitter) require email confirmation for new signups and password resets. This is not so different, the UX related commentary is superficial at best. After the initial activation / a reset you're back to cookie based auth, just like most sites.

Second, there is not a single mention of the biggest problem with passwords currently: the apparent inability of many sites to store them securely. I'll take this method of authentication over a password based one any day for probably 90% of the sites I have an account with currently. Especially sites like HN (not implying insecure password storage on HN - just saying for any forum based sites, it's more than adequate IMHO).
I usually find interesting content on showdead. I believe the time it takes me to skim/read dead content is worth the effort (the sn ratio is still better than slashdot).

I still feel bad about losethos. Wish we could help him/her somehow.
What's worse, in my experience, is when people are unable to provide the necessary information, even when questioned directly, because they don't understand or appreciate the assumptions they've been making.
> but something ~$100 might

What about the cost to innocent parties? Really dislike this!

> Domains under ~7 characters could be $100+, domains over 15 characters could be significantly cheaper.

Now that could be good - Charge inversely by the character.

Also has the side effect of discouraging URL shortening services :-)

I signed up, but the quality of the stream is really not that good. It fluctuates between 480 and sometimes hits up to 1500 for ten seconds. I never get the 3500kbps stream that I think should be available.
I understand captchas and so does the original article writer (if you read the article he clearly explains how reCAPTCHA works). While I would have agreed with you a couple of years ago, the author's point that reCAPTCHA has reached a point where it isn't working nearly as well is spot on. I myself fail on them about 75% of the time now -- quickly approaching the failure rate of computers.

For reCAPTCHA it used to be close to 100% success for me, but something has certainly changed with them, I don't know if it was intentional or is the result of a dwindling data set and as an end user, it doesn't matter, what matters is that they are really difficult to solve now.
And "programmer who likes his job".
The original texts are invaluable too. Sometimes ideas don't make as much sense to me after they've been re-explained by a second person.
Because calculus is the first class where functions (e.g. derive, indefinite intergration) take a function as its input, and outputs a function.
How Books Learn
Couple of big (agile) projects that I have worked had many "real testers" who weren't really coders (or couldn't really code). To them writing "natural language tests" was more suitable than producing code. The 'lower' level test-libs, that the acceptance tests relied, was either written some of the devs or the 'test-devs' in the test-automation team.
I capitalized "Server OS" because I specifically meant Windows Server. There are simply too many people using Windows Server with a mouse today that will be completely lost in Server 2012.

Microsoft's movement towards PowerShell is definitely a great change that's been happening over the past few years, but many Windows Server admins are novices with no command-line experience.
Sorry, I didn't mean to imply that "useful and readable" implies an n <= 7. Small n makes otherwise unintuitive or hard to remember things easier, but there are obviously longer "useful and readable" domains. Note, however, that while overcomingbias.com is useful, most domains in its immediate neighborhood are not. qvercomingbias.com, wvercomingbias.com, etc.
Founders Are Not Heroes. Let’s Get Back To Work.
I find it somewhat sloppy when journalists simply publish the Q&A transcript of an interview.

What I'm going to miss the most when real journalists aren't around anymore are the long-form articles and profiles that obviously took care and several interviews to craft. For example, the recently HN-featured profile of Jack Dorsey by Wired's Steven Levy[1]:

But our discussion is sidetracked when the proprietor, Vincent Fung, starts a long and complicated explanation of the various tea options. Dorsey—like Jobs—is interested in Eastern thought, and after listening to a detailed rundown of the exotic choices, he approves Fung’s suggestion to try a dark and musty chunk of Pu-erh tea from China’s Yunnan Province. A few minutes later, Fung appears at the booth with a deep wooden tray and begins a carefully choreographed ceremony, pouring a continuous stream of hot water over tiny cups. Then he pours water on top of a lid that partially covers the bowl containing densely packed cakes of tea. Dorsey watches the ritual and appreciatively touches his finger to a worn corner of the tray.

This is how an in-person interview is meant to be conveyed to the reader… not as a transcript.

Awesome stuff. Brings me back to the days of PindleBots. I agree about the late game content being pretty boring.
What about if they say they are only fluent in certain languages at the moment while having a basic knowledge in the languages that you use? Do you look more for ability to solve computer science and discrete math problems?

In this scheme, you and your wife would have different phones. You might still have to put in your user name to the browser once at the start of the session, or log out your wife.
This is one of those articles I wish I could downvote.

Soon, companies will be able to compete with gTLD, some have registered hundreds and will push them as the part of the internet for different topics. Google's ".lol" is probably the most obvious example, finally a place for all the funny sites.

After 27 years, people will start to get used to the fact that the internet is more than just ".com" (and maybe one's country's ccTLD).
That article indicts registering to purchase and has almost nothing to do with the password topic in question. Can you imagine having to wait for a login email every time you tried to make a purchase? Ugh!!

So what happens when someone's email account is compromised?

Currently there's a fair chance that the victim can reset passwords and change contact info for their online services before the hacker bothers to do so. But this would be impossible if email were used as the sole form of authentication.

I wonder if it would work to price domains based on how many you already have. Charging $(5 * n^2) would keep squatting down while still allowing individuals to own a few domains they're using.
Ask HN: Security of a username/pw combo vs a username of the same lenth

Why've you got one of Thilo Sarrazin's books featured in your screenshots?
You are absolutely correct, but the one thing you've failed to mention is that Steven Levy is one of the best technology writers of all time.

I got to see this process first-hand when he covered Weebly for Newsweek. (http://www.thedailybeast.com/newsweek/2007/05/20/meet-the-ne...).

It was an absolutely incredible experience. You met with the guy a few times, talked with him pretty openly about what you're doing, and he magically weaved a captivating story line out of it -- making everything sound way more interesting than you could ever hope to make yourself sound.

I'm sure there are a decreasing number of long-form journalists who take the time to research their story, but it's also worth noting that there just aren't that many journalists as talented as Steven Levy.
Valid points, especially the security issues.
That would be good, but that only works if you have a fool proof system to determine how many someone already has. And what if a company own's a domain name, does it count towards someone's limit? People might just start setting up shell companies to own domains.
send should never be used in a function that will not keep the CPU busy, such as one that calls Thread/sleep. send-off, which will allocate a new thread rather than taking up a slot in Clojure's fixed-size agent thread pool, should be used instead.

Ah, but that's forcing you to buy something you don't want (a long-term cable TV subscription) to get something you do want (streaming access to the Olympics on the internet--no TV involved).

As several posters here have said, clearly there is a value to being able to watch the Olympic events you want, live. There is no reason NBC could not charge a fixed access fee for people who don't have one of the "sponsoring" pay TV services.
It sounds extreemly draconian to me.

"anti-normative behaviour" is just an extreemly faux-elitist word for what business calls out of the box thinking.

It can be good or it can be bad, but a simple reduction to the mean (which is what it implies) is nearly by definition bad. Societies that are chaotic and disorderly may seem worse of than societies that march in lock-step and where everybody wears the same uniform and everybody is the same, but the latter society is guaranteed never to advance, no matter how far ahead its present state is.
I had totally forgotten about this :-(

Searching a little I found this interesting document addressing some of the problems which I have put on my reading list: "The Science of Thinking, and Science for Thinking: A Description of Cognitive Acceleration through Science Education (CASE)" (Philip Adey, 1999).

Assuming the idea of a "formal operational" stage of development applies, the situation looks abysmal (at least in the US and Germany, can't say much about other countries):

From the little I gathered so far (on the internet, so it has to be taken with a grain of salt) it seems that (1) a vast majority (over 60%) of people never reach formal operational maturity. (2) Ideas of how teaching can actually help with it are in it's infancy. (3) Application of said ideas is not very far along. (4) Educational systems keep leaving many (or most) students behind early, especially in math and science, while other students get bored and waste their time in class, being taught a mind-choking curriculum.

Ok, I guess I'm ranting now :-) Saddens me greatly, though.

Certainly a major issue, although the costs of maintaining those shell companies (taxes and fees and whatnot) may help check it somewhat.
Erlang and Clojure don't have threads in the common meaning of the term (http://en.wikipedia.org/wiki/Thread_(computing)). They are reactions against programming with threads.

You can expand the term "thread" to mean "concurrency in general" but even then it isn't true that the main purpose of writing concurrent code is clarity. When people say "look at this concurrent program I wrote" they rarely [1] say "look at how well the code expresses the problem". What they overwhelmingly say is "look at this benchmark".

[1] Joe Armstrong talks about how Erlang lets you represent processes more like they happen in the real world. But that's a niche view. Most people think about concurrency as a platform issue, where the platform is multicore hardware or distributed systems, and otherwise wouldn't bother with it.
Excellent, very well thought out post.

First time I saw the notion of diminishing effect of adding new users.

Would be great if author elaborated on various "how to" to mitigate this.
So why not just make the session last forever the same way, but using a password instead of requiring me to login to my email and click a link? I logged into Facebook the first time and as long as I didn't delete cookies, I could go to Facebook on that device today, tomorrow, next week, next month, next year... And never have to put my password in again.

This just adds more waste...
That is one option, allowing people to own the domain names but also allow many websites to somehow have the same name (with the unique identifier being IP or similar).

I've always been frustrated that the WWW URI doesn't support name-based virtual hosts in the authority section. While a name-based virtual host is usually specified as a domain name, it doesn't need to be. Many web sites share a single IP, so it should be possible to access them without requiring DNS resolution (examples showing name-based virtual host in brackets as one possible approach):

http://[www.example.com]192.0.2.1/
http://[www.example.org]192.0.2.1/
http://[www.example.net]192.0.2.1/
http://[foo]192.0.2.1/

Or requiring DNS resolution:

http://[www.example.org]www.example.com/
http://[foo]www.example.com/

Note that this doesn't serve the same purpose as a subdomain, because it allows one to explicitly specify the name-based virtual host to serve from a domain or IP address, instead of having a single part serve two very different purposes.

Of course there are issues. For example, you could create URIs like:

http://[www.google.com]192.0.2.1/

And SSL poses a challenge:

https://[www.example.org]www.example.com/
https://[foo]www.example.com/
https://[www.example.com]192.0.2.1/

But from a technical perspective, this opens up a lot of possibilities. Currently, the only way to achieve this is to write your own headers when making a request, so it's already possible, just not supported in mainstream clients.

I actually managed to find an insightful comment on that 4chan thread which I've edited slightly for clarity. I'm reposting it here because I think folks might find it an interesting perspective on the strengths and weaknesses of HN. It is also an opinion I happen to agree with.

Anyways, the appeal of Hacker News is the occasional interesting technical story, and the high quality comment threads that accompany it. Here's the LuaJIT author talking about implementing interpreters in C vs. Assembly:

You'll have to take my word for it, but there's a high technical barrier to appreciating this story, and it's accompanied by high quality discussion. If you enjoy reading about that kind of thing, it's well worth sifting through the startup launch pages, endless vim bullshit, reposts and blogspam, limitless iterations on "women in tech", and "how we scaled dick.ly with node and mongo" fluff pieces to find that delicious technical meat.

Am I crazy in thinking that this whole problem should have been solved a long time ago by making password management a responsibility of the browser, either by baking it in or mediating the exchange?

Combined with a simple standard for credential exchange (get request to example.com/login to get the list of required fields, post to https://example.com/login to login. Or more likely, some existing standard that handles more cases and is already thought out) this whole annoying problem is no longer affecting every person who uses the web.

Is it too late for this? I feel that it probably would be very difficult to make this work now, it's too late and the browsers wouldn't go up against google and facebook who now want to own and track your identity.

That makes me sad, that kind of stagnation cuts off whole important areas of progress for web users.

Social norms are different in different groups. I have told people that what they wrote could be considered racists and gotten a reply back that they wanted to be clear that they were racists, quite proud of it, and that I was an idiot for not seeing the muslim thread (in a discussion that was not at all related to terror). I have seen the same people belate others for questioning that we should throw all muslims out and arguing that every single muslim was a terrorist ala The Norwegian terrorist.
One can possibly indicate in this case it was 'noise', but constructive feedback on things like "we don't need to know about X, but we do need to know about Y" would be helpful.

"Quit sending so many emails!" is about all he'd generally get. In at least one case, I suspect it was more about control of information than anything else - when too much info gets to too many people, it's harder to claim plausible deniability.
I read it that the claim was that apple applies it's rules equally, which in plain reading wouldn't differentiate between a per submission and per submitter interpretation as it would be applying the rules equally regardless.

I was just meaning that if you were to go and try and find out whether apple were applying their rules reasonably equally, then you would need a lot more data than just the submissions of one individual, purely by the definition of what you are trying to research.
