I find the syntax of math very hard to parse (and I write and use parsers as part of my job).

For people who "get" math, I agree it's very difficult to understand how another, obviously intelligent person can find math difficult to understand and use – especially someone who has put in substantial, sustained effort and has zero problems with the command line, programming, algorithms, parsers and just computer science in general. It doesn't make any sense.

Except they do exist (I'm living proof).

Frankly, I'm baffled by the problem. I've read numerous books on math, taken tons of courses, and spent quite a bit of time trying to figure out why math, as a tool, is out of reach to me.

Sure, I can apply the "rules" at a purely syntactic level, but a good example of where math-like thinking is needed as a tool is with a language like Haskell, which I also find completely opposed to how I think about and see the world. I wish I knew why, because I'd like to use it. :(

So while I think the presentation is at least part of the problem, there's something about mathematics that needs to "click" before you can really make use of it, and that hasn't happened for me yet, despite literally _decades_ of trying.

If anyone has pointers for books, I'll be checking back here for comments.
This happened to me twice while trying to read this post.

It's frustrating how often a website will provide a client-specific rendering which is much worse than the default. (I'm looking at you, Wordpress).
Thanks for the suggestions, what is so difficult for me is i don't see progress. How i said, i don't think it is something to learn overnight. I just don't saw a starting point yet, in the technical world there is always a tutorial.

That book sounds very interesting, this is probably the thing i was looking for.
From your example, I can see it is possible to import sympy, and the app store page says that you added a few "extra" packages. Could you list those extra packages on your website?

Since it is not possible to import files for now, would you take requests to add new packages to that extra list?
Unless I can program and do something useful on the target device itself, it will remain a mere gadget. The novelty of "trying out new ideas in the interpreter" wears off quite quickly. My MBA is (almost) as light as an ipad, and much more useful (programming wise.)
Probably but it's still unfair (if the deal really is exclusive). It's also interesting how many goods are never invented due to the fact that experimenting with many substances is prohibitively expensive.

Stopped at #3. It seems incorrect. The answer states that foo returns x to the power of n. But I ruled that answer out since any 0 or negative n is going to return 1.

Couldn't some of those stomach bacteria be patched to produce Vitamin C? I suppose some humans already have such bacteria in their gut, without knowing it?
Not to take away from the work, but am I missing something? This strikes me as primarily being a visual design or what some people call a theme.

This is a great visual design. It's cohesive and incorporates zune/metro very well. I particularly like how the focus window is highlighted and everything else fades a little. However, I think this redesign (and Metro itself) also highlights how minimalism isn't necessarily the best trend to follow - at least not to the extremes. I see a design that's somewhat flat and we may perceive differently if the background was a solid colour.
This might be helpful too, a very good book on the basics:

The rule in question is not only silly but also relatively minor: I think it involves something like a $25 fine.

He wasn't doing anything horrible or dangerous, but was treated like a base criminal. And that's the real issue--a complete lack of decency and civility by people given additional power and trust by the state.
True. On the other hand, we aren't talking about a thoroughly developed community here. This sort of exacting law enforcement has its costs, and the balance of those costs should be evaluated in context. Given the limited industrial resources of this particular community I would be inclined to promote the retention of local infrastructure regardless of legal niceties.

It's also true that Israel has a history of limiting Palestinian development, of course. Sometimes for good reasons, sometimes not.

All in all I disagree that it's not relevant here. Maybe inflammatory, though.

> Won't let them fly on a plane together?

That's a common risk management tactic. It's literally in the textbook. Likewise, the Vice President flies on his own plane, Air Force Two, and never Air Force One. When the President and Vice President have to be in the same place at the same time, someone else in the chain of succession has to be kept somewhere else; most dramatically, when the President addresses a joint session of Congress, as in the State of the Union address, one cabinet member is named the "designated successor", is not allowed to attend, and is provided Presidential-level Secret Service protection for the duration.

How hard is it to theme "linux"(KDE/GNOME/ETC)? I've never done it as I don't use the Linux Desktop (I need Photoshop) but I've always wanted to try and help improve the linux desktop experience. Is anyone working on a theme actively or know someone to put me in touch with?
The quirks they pointed in the article seem relatively extreme.

I live with 2 other roommates and I don't seem them much these days because I work at home during the day. I feel so quiet sometimes being at home all alone. It is interesting that I will never know how an introvert feels staying home alone. The opposite is true an introvert will never know how a social person feels staying at home all alone.
Are you serious? "It's worse in tyrannical regimes"? That's your defense?

How about comparing to the US's contemporaries, like western Europe or Japan - the countries that are 'first-world nations'?

Pink Floyd - Echoes / Live at Pompei (full)
In both languages, the use of a variable is almost always preceded by a binding of that variable to a symbol or var using the "let" form. This accounts for most uses of variables, and attempting to access a misspelled variable will flag an error at compile-time.

With regard to destructive assignment, most Common Lisp compilers warn on setf calls when executed against unbound symbols. Clojure doesn't have even have assignment in the sense discussed here (refs are bound before use, and the compiler enforces this).
My Google Interview Experience
I recently went through the full breadth of the Google Interviewing process for the Software Engineering role. I didn't make it through, but that is not what made me upset, instead it was the lack of proper feedback on Google's side.

While I understand that they have legal issues giving out feedback, but I don't see why they can't dish out simple numeric scores for each of the interviews. That will at least make the candidate aware of how much he needs to improve, or if he can even improve enough to apply again, or it's just not worth retrying. This is specially expected from Google since they ask you to prepare a ton of material for around a month which is real hard work.

Anyways on to the real stuff. I cleared the only phone interview, which was very basic, shared Google Doc coding for about an hour. I was then called for a set of 5 onsite interviews, which were 45 minutes each. While I won't give out the exact questions because I want to abide by the confidentiality agreement, I will just try to summarize.

Two were design and implementation, two were algorithms, and one was algorithms and implementation, all of them required writing on the whiteboard. I think I did well on 3, ok on 1.5 and bad on 0.5. The average level of questions on a scale from 1-5 was a 4, 5 being the toughest, and I thought me doing good/ok in 4.5 was enough for an offer. Although I should make it clear that I did use hints from the interviewers sometimes, but not always.

If you ask me why I think I wasn't given an offer, I would say it must have been a combination of
me not being from an ivy league university, although I am masters in computer science from a within top 50 state university in US, with a near 4.0 GPA and I have around 5 years of work experience. Or it could have been that I might have not paid attention to little details which I thought were not important, but they really were, like forgetting an obvious parameter while designing a method of a class which I quickly rectified once pointed out by the interviewer. Or it could have been that in all my solutions I started out with the most basic worst time complexity algorithm (because I didn't want to stare blankly at the whiteboard for half an hour thinking about an optimal solution), and over time improved it, sometimes with hints and sometimes without. But I have to say I was really proud of at-least two non-trivial solutions I came up with. This sort of uncertainty is exactly the thing that could have been avoided by a simple feedback email from Google instead of them just informing you on phone that you weren't good enough.

I hope your Google Interview experience wasn't like mine, but I would really like to know how it went for you?

Thanks.
Yeah, unfortunately in the US, drinking in public is against the law, and if you are with people who are breaking the law, you are also considered a criminal. Although it is pretty fucked up, you should be aware of the local laws, especially if you are partying after midnight in public in any city.

I wish things were different, to be honest, but if you put yourself in the law enforcement officer's point of view, what's the difference between a few tourists enjoying a bottle of wine on the street, and a few drunken hooligans causing trouble and starting fights. I'm not saying you were doing anything like that, but a cop really can't discriminate.

I do believe the way they treated you was unacceptable, however, and you should file a complaint against the arresting officers. I believe in NYC you can dial 311 to do this. Police officers should be held to a higher standard and they are trained that the response to any situation should be justified - in other words: violent, belligerent drunk gets slammed into a wall and handcuffed. Happy, carefree drunk tourists should get calmly spoken with and given a warning.
Use Git, no matter what
Actually, no it doesn't, because people only need to see those buttons if they already have a relationship with the service in question.

Example: I don't have a Google+ account, so I don't need to see the +1 button. If you have a Google+ account, you would have a cookie, and thus be able to see the +1 button.
After a handful of side projects that never got the traction I was hoping for, I came upon Bret Victor's recent CUSEC talk on principle based inventing.

Unless you're lucky enough to stumble on an idea that has instant traction, any path to success is going to be hard, with lots of periods of self/market-doubt, and lots of opportunities to quit. I think the only way to get through those times is pursuing an idea that stems from a deep principle you believe in. This is currently what I'm looking for: identifying my humanistic principles, and seeing what ideas are natural conclusions from it. No more random market based ideas.
This cheat sheet is horrible. Subjectively and objectively:

* Bold fonts everywhere without enough vertical space: bold is for important stuff, not for copy text and the lack of vertical spacing makes the whole thing hard to parse.

* Keychars centered vertically instead of placed on a common baseline.

* Meanings of keys centered horizontally: considered very hard to read since forever.

* No explanation for `WORD`: is it for uppercase words? (yes, I know the answer)

* Instead of being logically grouped, the commands and motions are tied to the spatial location of their key: the logic and grammar behind most of Vim is hidden in profit of an opaque, maximalist and almost unreadable mess.

* Focus is put on raw memory instead of intelligence and acquiring instant exhaustive knowledge instead of learning naturally.

* QWERTY is only one of many keyboard layout standards: a lot of the keys represented here are located elsewhere in french AZERTY or other layouts. This has one important consequence: the physical location of the keys bound to each command/motion is not linked at all to the name of the command or its mnemonic or to anything relevant. Because `A` can be anywhere, learning the physical location of "Append at eol" on this specific keyboard layout or on any other makes no sense at all.

But we obviously don't all learn the same way.
I don't know if CVS or Walgreens would have a reason to stock in at the local store, but they could likely get it from their regular distribution. Yes, a medical doctor can prescribe this but it takes considerable extra paperwork (and receives DEA scrutiny). It would likely be more common in a hospital setting, usually as one ingredient in a compound.
This is cool.

Are you caching the data? It would be cool to see a graphical interface of this over time. The guys at insidefacebook have done a nice iteration of this idea on the analytics of facebook apps and pages (http://pagedata.appdata.com)

It would also be cool if you could somehow integrate Compete and Quantcast into here too (not that any of those three are terribly accurate - but would be fun to look at).
Extreme? I sent the article to a friend who has lived alone for many years, as have I, and we laughed about how minor the eccentricities in the article seemed.

without any duplicates.

That way, I would have three bookmarks:

http://www.newsola.com/#/ca/w,n,b - my default Canada-centric news page

http://www.newsola.com/#/ca/tc/UNION/#/us/tc - for tech

www.newsola.com/#/ca/s/PLUS/#/ca/e/UNION/#/us/e - for sports and entertainment (emphasis on CDN sport, i.e., more hockey, less baseball, with US and CA entertainment - in fact, I could add Britain too, e.g., to keep up with Blake's 7 and Red Dwarf news).

A single blanket assertion with nothing new, no argument, no insight is flamebait, not advice. What part of that comment would tell anything to someone who didn't already believe it? Do you think there is some European reader who has never given a moment of thought to the existence of America, encounters that comment, and goes, Aha! It turns out that America is fucked up! I'd better remember that! I don't think that reader exists.
Good point, but you can also probably get the permits far more easily than a Palestinian living in the West Bank who doesn't speak the language of the government that he does not recognize.
Very fun article.

Perhaps we'll be able to eliminate the bacteria one day, but it's a tall tall order. Beyond a certain level of complexity paratisitism seems to spontaneously emerge for reasons we don't fully understand. To avoid it you'd have to either centrally design (micromanage) complex systems at least 4 orders of magnitude larger than anything attempted so far, or you'd have to come up with a set of simple rules that causes complex behavior without parasitism. I suspect the latter especially is an ill-posed meaningless question.

Personally I think all our largest codebases today already have a parasitism 'problem'. They suffer from two kinds of parasites: dead code and crappy programmers living off maintaining them.

I would bet on attaining immortality before eliminating parasites from the human body. It's not a bug but a feature.
The difference is that you'd have a reasonable chance of being able to get authorization.
> Letting "integers" silently overflow is weak typing.

"Weak typing" is a broad concept, but that's not one of the ideas that it covers. In any case, Python's conversion of integers to long integers is not transparent. It is an actual change to a different type, which is an example of weak typing.

How is this story and thread relevant to HN?
That's true, of course, but modern DRM schemes anticipate exactly that, and so they put lots of effort into making it cost-prohibitive to break the scheme in under 2 weeks.

Maybe it's the case that everyone has backed off Blu-Ray because of Slysoft, but either way: BD+ has protected the new-release window for Blu-Ray disks in several instances (you can check out the Slysoft message boards to see when that's happening).

If you want to see an example of an (as far as I know) unbroken DRM scheme, look at the modern crypto cards in satellite TV systems.

Another solution (albeit more costly) would be to re-hinge the door so it swings outwards, and make the springs easy enough so people can push it open using their shoes.

That's not the gentleman's way of operating a door, but with the trashcan solution people also have to hold the door open somehow while disposing of the towel, unless it comes with springs that are adjusted just right so it stays open just long enough for people to sneak out in time.

Making the door open outwards is the right thing to do anyway with regards to fire safety, as far as I understand.

Of course, if you have the space to spare (without things getting too intimate) you can also just leave out the doors altogether, which is how many airports I've been to seem to handle the issue.

(I'd say an automatic bathroom door is overkill and a bit creepy, too, which probably is why I've never seen one.)
