I see so many "why don't they just do X, it would make more sense" arguments about all kinds of government programs. The reason that don't in every case is because from the government's perspective the program is working great! The existing medallion owners very much like being able to charge monopoly prices. The city politicians very much like that the medallion owners lobby them to keep the system in place and support their campaigns. Why would they want to mess with something that works just fine? You are not the government. It doesn't serve your interests. It serves it's own interests.
It's related to double buffering and vsync together. If the pure rendering performance was 45fps, when the render is complete the next render can't progress until the buffer currently being displayed is available - hence degrades to 30 fps.

The commentors complaining that their pet style is not included seem to be missing the point of an idiomatic CSS guide. I have seen the one rule per line in the wild, but it is rare. The CSS the author has shown is fairly representative of what I see in production code.

However, the author should have stuck to plain CSS instead of including the syntax favored by SCSS. Some of the syntax is specific to the later. Single line comments are a particularly egregious example; they can appear to work in vanilla CSS, but that's only because they force a syntax error that makes the parser skips the line. Including such syntax defeats the entire purpose of the guide.

Is there a good reason why someone hasn't done a Dollar Shave Club business model for printers + inks? I would think it would decimate the ink racket.

Granted, it may have been tried numerous times and failed due to the hardware dominance the major printer players enjoy (and throwing out an existing printer isn't the same as throwing out a razor from Gillette, so you have to capture transitional customers). And of course hair grows fairly consistently, whereas ink usage is less consistent - but offices can always stock back a couple cartridges if they're not using enough and downgrade their account with the click of a button until they burn through them.
> I agree. I've never successfully gotten a cab to take me to LGA

You probably already know this, but always get in the cab first (if possible), then tell them you're going to LGA. Cabbies aren't allowed to turn down a fare in city limits once you're already in the cab. If they protest, snap a photo of their badge # and tell them you know the law - most will give up and take you where you want to go. It's a pain in the ass, but you gotta do it sometimes.
Some websites allow you to sort printers by price. They then list the cartridges that you can use with those printers.

But some people would want to sort the carts by price, and then see the printers that accept those carts. These people can't (for whatever reason) use toner refills or third-party carts. (There is a complication with number of sheets printer per cart, but that's easy enough to fix.)

And if you're a toner refill company some people will buy printers based on how much they'll have to spend to get new toner, so listing your cheapest print-per-page refill kit would be useful.

There have been 'disrupters' at work for many years now. I wish people wouldn't assume that (a) this sort of market distortion hasn't been noticed for years, (b) leveraged for almost as many, and (c) that there are actually reasons why the market delivers these prices.

Email me. I need help from time to time.

Also put your email in your profile. :-) I would have contacted you directly.

FWIW, i have had bad experiences (poor quality work) with Elance, so I no longer look there.
Using the Montessori method would have solved many of the issues presented by the OP.

Dave would have been in a group where he'd be able to show others directly, if Dave wasn't in a group, he'd be quickly identified by the teacher as someone who didn't need help and could possibly benefit the group.

Dave: <obscure question about array semantics>
Teacher: Dave, it looks like you know a lot about arrays, Laura is struggling a bit, can you help her out?

Dave was seeking attention and to be recognized as having advanced skill, the Montessori method would have allowed Dave to put his talents to good use while not being a disruption to the class.

Dave isn't a jerk, it's just that the instructor is using antiquated teaching methods from the 19th century, and under utilizing his teaching resources. Clearly this person is someone who's authority should indeed be challenged.
I use some of these tools, thanks for the post. I think that there are a lot of people who are unaware that they can have an attractive and (sometimes profoundly useful, depending on what you do) shell experience.
You may be overestimating the sophistication of these algorithms.

At least for this training set, my algorithm rewarded the length of the essay most of all (something like 65% of the total prediction). The only other significant factors were misspellings and prevalence of certain parts of speech.

That model matched the accuracy of human graders and several commercial essay grading packages.

Students reverse-engineering comparable algorithms won't necessarily have to write well to score well.

Why Bother With Cucumber Testing?
While Mount and Blade is one of my favorite games of all time, its sword fighting is pretty different to the simulation in Die by the Sword. DbtS didn't really have pre-programmed motions like M&B, it instead attempted to map 2D mouse position to 3D hand position using a physical model of the player's skeleton (which generally resulted in flailing madly with your arm contorted into bonkers positions for the first week of play).
All these sites have to do is store the passwords using bcrypt and with salts and they're pretty much uncrackable (as far as we know).

The reason they're uncrackable is because when using bcrypt it takes a second or more to generate a hash for a password (compared to 0.000001 seconds for md5) meaning if they want to try and brute force the password or build a rainbow table it'll take them years instead of seconds to crack each password.

There's no need to remote password storage, they just need to learn more about password security.

Savannah Fund: Mobilizing The New Tech Revolution in Africa
It's interesting that many outside of tech circles seem to be fascinated with Bitcoin. I have no opinion on alternative currency, but I have an issues with Bitcoin as an approach to alternative currency: it's a power hog. To use the politically correct terminology, it's not "green". Not even close. While it has its appeal to nerds because it uses the computer, it is an ecologically unsound idea when you consider "scaling up". How much energy does it take to produce paper currency? How much to generate "bitcoins"?

Given the world's energy situation, it's neither a smart nor a feasible "implementation" of alternative currency.

Ask HN: why are taxi rip-offs so common?
My experience taking taxis in Amman, Athens or Madrid as a foreigner is running a risk of getting ripped off (in decreasing order). I doubt I'm the only one.

This is, of course, not a rule, as there are honest and dishonest taxi drivers everywhere, etc.

Why, if I take a taxi in Berlin or Manchester, I can relax, but not in those cities? It's not the same with other services.

What's failing in those markets, which could be fixed?

Um, no shit. I sure did. Although it took me until seventeen until I was scripted something "effective". Unfortunately, for some of us, the regular hit of an irregular dose of dopamine (and other stuff, norepenephrine, etc...) will lead to a pattern of abuse that will eventually screw you over more than your seventeen year-old mind could ever comprehend. At least, it did for me. I won't go into specifics unless people ask for them, but things became difficult after a while. And this is is how it started. Take an Adderall. Feel awesome. Feel smarter and more able than you've ever felt before... Even if you are aware that it is artificial, or at least that you are augmented, well - the brain wants what it wants.

There's a natural experiment in England where there are quite a lot of single sex schools. There are a bunch of confounding factors that are hard to kludge out - social-economic backgrounds, etc.

Forking a project has always been an option of last resort in open source. Doing so while stealing the name is downright nasty.
Same here, with a recent HP color laser printer. It's not worth the hassle for me to use the third-party cartridges.
Ah OK. I was assuming a world in which triple-buffering was a given; in other words, that vsync in practice was a rendering implementation detail for avoiding tearing, rather than something that blocked the renderer. I can see how things are different on a resource-constrained device that can't afford triple-buffering.

I'll add that usually you don't see a constant rate of rendering performance. Render time for a frame wanders above or below 16.67ms (with the design target being under that, if 60fps is the aim) depending on complexity or how busy other tasks are. It's not usually the case that every frame takes 22ms (i.e. 45fps) to produce; so it would be very unusual to see a game / app flip from 60fps straight to a locked 30fps. Rather, the odd frame will take slightly more than 16.666, with most falling under. The statistical distribution will give an FPS rate somewhere between 30 and 60.
Many people would claim the military use is intended for the Good. Opinions differ.
Let's say you can resell that printer for half the price, without cartridges, and buy a new one. How about then?

Freelancing / development companies are businesses. A developer just getting started as a freelancer _is_ a startup. Try taking a serious run at two startups at the same time. It's hard, and I think that's your answer.
Since (1) US taxes are relatively low on high income earners (right now anyway) (2) you can usually use the US taxes you pay as a credit against any foreign taxes you owe, is this actually a big problem in practice? Perhaps if you are making a large income and currently reside in a country with very low taxes, I suppose.
How is industry regulation different in those markets? When you get ripped off, what is your recourse in Amman, Athens, or Madrid? What can you do about it in Berlin or Manchester?
You can buy a decent Brother monochrome laser printer (auto duplex, wireless, and wired networking) for ~$60-80 on sale and the generic toner for $10-20 for 2,600 pages.

For most people this is a far better option than buying the Brother brand toner. Worst case, it ruins the printer and you buy another one for that $50! I have had great success with the generic toner so far, nothing ruined or leaky yet.
To offer a different perspective, I disagree with jnorthrop and think your value proposition is clear - you're helping companies encourage customers to share purchases and provide metrics of how that sharing affects the bottom line.

I like the idea and think it's clever.
Your back-building of coincidence is essentially Chekov's gun, viewed from another angle. A potential downside is that if it isn't very artfully placed, the reader will see the significance before the characters, and grow frustrated at their idiocy.
In all probability, anyone setting out to actually defeat these algorithms could easily do it with a couple of hundred repetitions of the same sentence.

Or, if it's slightly cleverer than that, certainly you could defeat it by producing a single, perfect-length, stylistically fantastic essay... which would be regurgitated word-for-word regardless of the subject matter.

I think, mind you, that software does have a place in analyzing student essays. If I could scan in an essay and have it spit out a word count, highlight any spelling errors or potentially problematic turns of phrase, and [most importantly] analyze for plagiarism, that would be valuable.
Anyone know any good references for transitioning from bash to zsh? Particularly thinking about converting .bash_aliases, .bash_profile, and .bashrc. What are the ZSH equivalents?

Also I get the impression the poster uses ZSH, Tmux, and Vim. I use Vim and Tmux too, but unfortunately not at the same time if I can help it. There are one or two Vim commands that don't work in Tmux because of a key mapping conflict. Been so long since I've tried that I can't remember exactly what the conflict is, but does anyone know what I'm talking about and know of a solution?

Edit: Thanks everyone, very helpful. Also, in case anyone else wondering, after a little research, it appears the syntax for aliases are the same for .bashrc/.bash_aliases, .profile, and .zshrc.

So I moved all my aliases to .aliases and sourced that file .bash_aliases, .zshrc, (and .profile but I don't think it's needed here. also didn't seem to work when I sourced it in .profile only and not the other two).
This article seems to imply that part of the reason is that Japanese has 3 sets of symbols for the sounds in their language, which makes typing difficult.

Why does Japanese use 3 sets of symbols for their spoken language? (Hiragana for native words, Katakana for foreign words, Kanji due to China's proximity?) Why not reduce to one set of symbols?
When I left the place, he was talking to the Faculty's security staff, and he was accompanied by people from a foundation (the one which usually organizes his events here) at all times. They said he slept well and was calm today.
I disagree with this summation for one reason, both he and Gates are tied to the dawn on the PC revolution as such their personal history is intertwined with an important time in human history. Much like those whose history is tied to the renascence. I think they will be remembered because of their being anchored to an important time, much as Ford is remembered for being anchored to the industrial revolution. One cannot negate the surrounding macro history when taking into account how history will favor the micro actors in that time.
This is great. I have to work with some very complex excel/VBA apps and this will be a breath of fresh air.

TL;DR: hardware becomes software, IP erosion and democratisation of manufacturing changes design, design process, distribution and business models.

3D printing involves the digitisation of (some/parts of) physical objects, which means that the manufacturing and design industry will face the same challenges and opportunities as the music/entertainment/publishing industries. As the article suggested, we'll see a leveler playing field and IP issues. Where it gets interesting is how these two things influence the life of a physical product.

Hardware will become more like software. This means open source hardware will become a viable alternative and threat to existing proprietary "hardware" companies in certain industries. I suspect that we will see history repeat with a concentrated market-don't-share of retail portals (iDesigns, Google Blueprint...) and design brands in the hands of a few and a long tail cottage industry will play out in the hardware industries that are suited to 3D printing.

Having said that, because the way physical products are consumed/used is more diverse than software and because of inherent differences to software, the future of hardware will play out in a more varied way to software.

For example, consider a high-tech Ikea, in which currently unprintable parts (electronics, batteries etc) are mailed out to you while you print and assemble the rest yourself, choosing from the 25 official designs or the 3286 unwarrantied designs. You won't stick out of the crowd, but a DUbuntu LTS design is a safe bet. The price reductions (massive) will justify the labour, even for non-hackers. Manufacturing (think much of Asia) will need to reinvent itself as a design studio. We leave industrialisation further behind as manufacturing capability becomes a given and design becomes the differentiator.

However, the contracts are usually written to say that any parts which are found to be illegal are severed from the contract, so as long as such clauses are allowed, very few contracts are likely to illegal.

Ask HN: Would salted passwords have helped LinkedIn? Should we still use them?
A roommate asked me this question, and I was curious as to whether there's some insight that I'm lacking.

His arguments:

1) If the salts are stored in the database with the hashes, wouldn't it still be possible to brute-force/attack the salt+hash combination?

2) In the context of [0], don't advances in parallel computing (particularly wrt. "general-purpose" computing on GPUs) make it relatively easy to generate a rainbow table for each salt encountered (compared to, say, two, or even seven years ago)?

Will this help the nearly-illiterate masses? I think so. Will it hurt those who are one standard deviation or more above the norm? I think that's a problem, too. The solution then is to use the algorithm on the first set and more individual-oriented grading methods for the other set. Effort should be spent finding those in the other set and that isn't restricted to a single course or assignment. This challenges the assumption that students are equal and deserve equal grading, but I don't really see another way forward that doesn't hurt any of the best, mediocre, or poor writers.
