> I really can't believe you referred to a student as a client. It just feels to me completely against the spirit of education.

Actually, I can completely understand why the OP would say something like this, and I can see the value in it.

Calling a student a "client" can be a good reminder that, as a teacher, your main responsibility is delivering something of value -- knowledge and understanding -- to that student. I think that's more congruent with the "spirit of education" than thinking a teacher's primary responsibility is to whatever organization they're part of. (Note: I'm not at all implying you were saying that! Only that some poorer teachers seem to act that way.)

Here's something I can't figure out. I saw a list price of the Model S 60Kw as $62,400. The article says you pay $1,097 for 63 months for that model, and you can sell it back at 43% of the original price. Okay, at 36 months, you've paid $39,492 in payments. Assuming Tesla buys back at 43% of the $62,400 price, or $26,832 and you get that money, then all you are out at the end of 36 months is $12,660 or an effective $351/month (but only realized after three years).

Am I missing something here? Is my math off?
Yeah, copying GitHub URLs sucks. You cannot actually select it with your mouse, since some creepy JavaScript interferes and selects it for you. the result is that it's selected, but not copied to PRIMARY, as you'd expect. I fall into this trap every single time.
> This is really just an extension of clickjacking

That's was my first thought too, but in fact, it's quite the reverse of clickjacking (even though the same basic idea is used).

With clickjacking, you would positionate some opacity:0 link on top of some apparently legit link. Here, on the contrary, the malicious content is within the apparently legit content, then moved away with css (setting opacity to 0 would not do the trick).

Not a big difference, but that would deserve a dedicated name, IMO.
Following that paper, a friend and I implemented a simple MCMC-based synthesizer for the GreenArrays chip (a very low-power and rather obtuse architecture based on a variant of Forth).

Most of the code is up on GitHub in several different repos[1][2]. I'm actually rather proud of some of the code, especially part of the F18A interpreter (F18A is the name of the instruction set on GreenArrays chips). It's rather short and neat.

[1]: https://github.com/TikhonJelvis/array-forth

[2]: https://github.com/jacobt/mcmc-synthesis

My version actually supports loops and even self-modifying code. This no doubt has some performance implications--my current approach is to throttle each test case to take at most as many steps as the input program does. For various reasons, I found it easier to just allow loops than to try to stick to loop-free code.

I found that their correctness measure--looking at the number of bits that differs from the expected result--was basically useless for GreenArrays. I actually have some graphs lying around which show how it basically doesn't vary until it suddenly finds a correct program and shoots up to being 100% correct immediately. It does not exhibit the nice hill-climbing behavior that we want.

For better or worse, I have not been able to get this style of approach to perform as well as a similar synthesizer using an SMT solver (namely Microsoft's Z3). The advantage with the MCMC system is that it's easily parallelizable. It can also deal with certain programs that can choke up the SMT-based version.

The SMT-based system has problems dealing with lots of bits, so we usually run it pretending that the architecture uses ~4 bits instead of 18 (yes, it uses 18 by default!). So for problems requiring more precision, the MCMC approach might be better. Similarly, the SMT system does not model memory terribly efficiently, so problems needing a lot of mutated memory might be better for the randomized system.

Also, I should add that I know literally nothing about machine learning and even less about SMT solvers, so it's not surprise that the things I have written don't perform terribly well. Basically, my only solace is that this project's code is mostly rather elegant. I learned quite a bit about programming at a high level of abstraction from this project--some of the things I ended up doing rely on significantly more abstract reasoning than anything I've done before.

Anyhow, it's cool to see people reading about something I've been playing around with for a while now. Even if I find the whole field a trifle annoying :P.

If you want to play around with this sort of synthesizer, I have uploaded both a generic library based around MCMC[3]--it's surprisingly simple--and the GreenArrays-specific code[4] to cabal, so they're both just a cabal install away.

>Teachers, who don’t receive outlandish wages or pensions, didn’t cause this problem, and the good news for them is that they will get their pensions because the state is legally required to back up school districts if they can’t meet their commitments.

How can teachers be completely absolved of responsibility for the current situation, considering that teacher's unions were at least partly responsible for negotiating the pension contents? Obviously the individual teachers or administrators never wanted a bankrupt system, but when you hand off representation to your union without taking responsibility for long term sustainability, stuff like this happens. Look at the Automobile Unions; basically the same sort of setup.
A manipulation that I don't see the point of, at that. Tell a people who can only afford a $600/mo payment that the TCO is under that, and it might get them to come into the dealership, but the real monthly cost will come out before the car could be sold.

If they pitched the calculator on the "true cost of ownership" page as a "here's a way to estimate the hidden costs of a gasoline car that make the Tesla more competitive than you'd think" they could make the same pitch but without the smell of a bait and switch. But even at that, it's not apples to apples (if you buy an S Class, nobody has to guarantee that there will be a market for reselling it in three years).
Lot's of Java dev greatly misunderstand ORMs and the underlying SQL stuff. You can differentiate on that.
The page was about T-Mobile USA, formerly known as VoiceStream. Nowadays, it is owned by Deutsche Telekom, but it has little to do with the T-Mobile brand in other countries. T-Mobile USA doesn't offer domain or web hosting services. T-Mobile USA mostly just sells budget cellphone plans. They're a small player trying to gain more marketshare.

I suspect you're talking about T-Mobile Hungary which, like T-Mobile in other European countries, is the largest carrier in the country and really couldn't care less about its customers. (I'm a subscriber with T-Mobile in The Netherlands, where the company isn't dominant. The situation is better here.)
Why not try engaging your brain before spewing another "think of the children" post onto the internets?

Calpers has argued that California is legally obligated to pay all pensions in full due to the California constitution. If the pension fund falls short, who do you think will suffer cuts? Hey, that's right. The kids of today, who will have to deal with fewer teachers, bigger classes, and so forth.

David Crane is arguing that we should actually fund the pension fund properly rather than using Enron-style accounting tricks and ridiculous assumptions to kick the can down the road. For saying this, he lost his seat on the board.

People deserve to know where their money is really going. If we need to pass an emergency tax to fund pensions, let's call it that, rather than dishonestly pretending it's to expand education.

What makes it better than, for example, Jekyll?
No, your math is right. The $500 per month figure is for the 85 kWh car, which is more expensive. Tesla's "calculator" gives roughly the same figure as you for the 60kWh car. That doesn't mean it's comparable to a car payment of $351/month though. If you did equivalent discounting to a car that only had a $351/month payment (maybe some sort of Kia?) then that would come out to be in the ball park of $150/month, but you don't see Kia advertising their cars like that.

I thought the section on retina images was worth it's own blog post, and not covered by pagespeed.
I don't understand what this has to do with copying or pasting at all. I would still copy-paste it.
Ah yes, the classic Somalia-strawman.
I did my math on the 85 kWh version and it came out to $417/month (effective after three years and selling it back). But you are right, you don't see other cars being advertised like that.
Most interesting part for me was the suggested use of SVG in lieu of retina optimized images. As someone doing a project in D3.js this is eye opening.

He said "plus the cost of maintenance and electricity".

For equivalent range, a Model S would cost me $8 per "fill-up" instead of $74. The difference would be bigger if I drove a sportier car with worse gas mileage.

Isn't this the case with a lot of Android devices, regardless of the SoC vendor or device manufacturer? There are tons of devices out there that are stuck on Android GB or older, not because of hardware limitations but because of software.

Android is not a very stable platform, there's a big code release coming from Google once or twice a year and it's a lot of work to make drivers and other software play nice with the new version. Device manufacturers and SoC vendors have no financial motivation on keeping the software up to date with previous generation devices, the priorities are on shipping new devices.

This is the biggest problem I see in the Android ecosystem. Smartphones and tablets reach the end of their life prematurely when you can't use the latest software even if the hardware has capabilities to run it. When I buy a high end device, I expect it to serve me for 5 years or so and stay up to date with the software.
No doubt. I don't even understand the business reasoning behind closed source drivers at this point, especially with AMD on the rocks.

After making $39,492 in payments, you still owe $22,908 on the car (well, not exactly, because I'm not accounting for the down payment or for interest on the loan, here—but you don't own the car free and clear). So that $26,832 doesn't all go straight into your pocket if you sell the car back.

That's why, in order to get to the $346 figure I'm seeing on loading up the page with the default options for the 60kWh model, most of the "savings" comes from stuff other than the buyback (primarily the business tax benefit and fuel costs). The guaranteed resale value portion is only credited a $40/month benefit.

All of what you said is 100% true about T-Mobile USA. Just to amend, their tech support and customer service is similar. From friends I know that deal with them, they outsource all their tech support to firms with employees that can barely speak English and are inadequately trained. I don't like dealing with Verizon (Vodaphone for those outside the US) customer service either, but their service is still leap years ahead.

This thread illustrates exactly the problem with HTTPS.

The proponents of HTTPS everywhere try to sweep the significant downsides under the rug, whilst others are spreading all kinds of unfounded FUD about HTTPS.

The bottom line is that "your mileage may vary". For some applications, SSL is trivial, and there is no excuse not to do it. For other scenarios it's a nightmare with all kinds of undocumented complications.

I'm currently working on providing SSL for a SaaS service with various client domains on AWS (i.e., with a limited number of IP-addresses). Doable, but far from trivial or inexpensive.

Backbone Tips: Rendering Views and Their ChildViews
Judging by fines and jail times they already are.
In California, the union didn't just negotiate the contracts from one side of the table. The California Teacher's Association (CTA) is, by amount spent, the most powerful entity in state politics (to say nothing of volunteer 'ground troops'). Thus they control both sides of the negotiating table, and also usually get what they want via the initiative process, as with 1988's Prop 98 (guaranteeing school funding by formula) or 2012's Prop 30 (as noted by this article, bailing out teachers' underfunded pensions).

Here's a nice exegesis of their role over the last 40 years:

http://www.city-journal.org/2012/22_2_california-teachers-as...

If it's part of school finance or operations in California, and it's broken, it's because the CTA made it that way.
