They're designed to be frustrating at first so you'll figure out what you're missing.

You know you know the material when you can understand everything at the speed it's presented. (Chopping everything in 2-5 minute blocks helps with that too. Worst case, memorize everything and move on.)

[also, the posted content was part of a second level linear algebra course, so a lot of it is presented as a series of bullet points with just enough detail to jog existing memories of terms/definitions/how things interact.]

Also, that's just some kind guy who has a PhD in particle physics at Princeton who volunteered to let me record him saying things with no coaching or guide at all. There was zero coordination between the hour he talked while I recorded him versus the month I spent adding incoherent flying equations everywhere.

Pity. The only MOOC I have ever finished, and truly enjoyed, was Thrun's "Artificial Intelligence for Robotics". It was magnificent to get an easy to follow introduction into a deep academic field by someone who is so demonstrably accomplished.

I know that I'm just being selfish here, but I was hoping that Udacity will continue on that path. I would love to learn celestial mechanics from Belbruno, or neural networks from Hinton, or operation system design from Linus in the accesible Udacity style. It seems that won't happen any time soon, or ever.

For the most part, yes. Some fragments survived, but the majority of what we know about the pre-Socratics has been filtered through later doxographical works. While it certainly isn't optimal, together there's certainly enough of an understanding of the majority of the pre-Socratics to discuss them in a philosophical context without relegating them to Classics departments. Particularly given their relation to later thinkers. If you're interested, this article is an interesting place to start:

Just to clarify. My "Learn Ruby on Rails" covers git and GitHub. Readers tell me they like the "time traveler" analog I use to introduce git in a gentle way. My book is for beginners who want to learn real-world Rails, so it covers professional practices including git, user stories, project management, configuration, using APIs, and more.
Also, I wasn't to fond of using black background and bright colored squigly writing for learning calculus. I have ADHD and learning math and calculus has been such a huge challenge. But I found work done by patrickjmt[1] to be amazing. It's clear neat and concise, and was able to get through Single and Multivariable thanks to him. My girlfriend and my sister really loved the way he explained calculus as well.

I know linear algebra and I was still very frustrated.
The key quote from this article is right here:

"I think Thrun's elite background led him down a garden path. Any San Jose State professor who had taught an introduction to statistics could have told him that many (most?) of his students would not have basic arithmetic skills and would "hate math." They are not Stanford students."

Thrun is an elite academic. He has most likely never even attended a university that had to teach remedial math courses, let alone taken or taught one. Thus, by extension, he has likely never had to deal with students who had anything but excellent preparation for studying the material he was teaching.

I sat through most of Thrun's AI lectures and I felt that he and Norvig were questionable teachers. They are clearly brilliant men, and their excitement was contagious. They would be tremendous guest-lecturers in any CS course (the particle filter lectures were Thrun's best because he was so excited, but he spent most of his time gushing about how cool the ideas were). But as far as teaching a course to non-Stanford students without the help of an army of TAs, they were uninspired.

Compare Thrun's experience with the sentiments in this article about Miami University in Ohio: http://www.propublica.org/article/on-country-club-campuses-a...

The common vein is that education is fairly easy when the people you are educating are well-prepared and generally hail from the upper half of the socioeconomic spectrum.

Teaching poor kids, and kids who, for other reasons do not have adequate preparation is really something of a Sisyphean task. The problem is not in our schools, and it can't be fixed by fiddling with the curriculum or delivery method, it can only be truly fixed by fixing the underlying social problems, but that usually means talking about sticky issues like racism, sexism, ethno-centrism, and capitalism itself.

Yeah, you try that.

This "go ahead, host it yourself" is disingenious and manipulative at best.

And what are employers doing, attempting to confront their employees about it?

Once you go thread-safe, RC updates become extremely expensive, while concurrent GC is well-studied and performant.

This is simply false. In fact, concurrent versions of deferred reference counting have been known and studied for years [1]. The simple solution is to store the RC updates in a buffer and execute them only during a collection phase.

Pause time is a form of overhead. It reduces both latency and throughput.

Yes, but for many applications (e.g., HPC) only amortized cost is relevant.

Note also that you can do cycle detection concurrently with the mutator's operation (again, see [1]). Concurrent cycle detection makes the implementation more complicated, but no more so than a concurrent tracing scheme. Moreover, if your program is indeed performance-critical, RC schemes allow you to minimize the impact on cycle detection by designing your code so as to avoid cycles (either by using acyclic data structures exclusively or by using weak pointers). Conversely, tracing schemes make it difficult to programmatically influence worst case pause time.

Even if this was feasible, atmospheric heating from the microwaves interacting with the atmosphere (as well as water vapor and particles in it) would be a real problem. This would be equivalent to the Sun heating the earth+atmosphere on the order of a few percent more than it already does (see below).

This seems like a pretty intractable problem with these sorts of plans to beam energy to earth.

---
showing my work...

Microwaves attenuate in the atmosphere at about 15 dB/km or 3%/km (see http://dspace.mit.edu/bitstream/handle/1721.1/4963/RLE-TR-08...). If the signal is losing power, its going somewhere: notably as energy (some converted to heat) into the atmosphere.

If you're sending 13 PetaWatts (as indicated in the original link) through 10+ km of atmosphere, that's 3.400 PetaWatts, or 26% of the power, "lost" on the way to earth. All the power that's "lost" is being absorbed by the atmosphere and contributing to atmospheric heating.

The earth gets 174 Petawatts of incoming radiation from the Sun (http://en.wikipedia.org/wiki/Solar_energy), but 30% of that actually gets reflected back, so the Sun heats with 122 PW of incoming solar radiation and this plan would add 3.4 PW, 3% more.

Note that I didn't take into account the thinning of the atmosphere or the fact that not all the energy goes into heat (some of it could be absorbed in other ways). However, you still end up with some pretty significant additional heating and having microwaves absorbed by doing things like breaking chemical bonds in the atmosphere probably isn't a great thing either.

According to TVTropes, under Wire Dilemma, Get Smart also had an instance of it around the same time, which leads me to believe that it was a widespread trope even then.

There is an idea that it originated in WWII, when some German bombs featured overly complicated designs that purposely didn't explode all the time, because a live bomb is arguably worse than an already exploded bomb.

While I understand where you're coming from with this... it seems pretty naive/optimistic to honestly expect most people to behave this reasonably. Most people are not as smart as you and/or have some holier-than-thou moral perspective to throw into the mix and wouldn't have the first clue how to respond appropriately to something like this.

It's clear that the author is frustrated though. Maybe it's just me but I feel like a framework's core team should treat security vulnerabilities (or even common design patterns that lead to them) as stop-the-world events until they are resolved.

It's not up to the issue reporter to come up with a fix that satisfies the core team.
It's commendable that you're able to recognize that you have no frame of reference for understanding the distress, but don't go on to dismiss it as irrelevant or the result of overreaction. Too many people stop at that first step.

It's a shame Udacity hasn't worked as well as Thrun hoped. I'm convinced that the failure of existing online courses has been primarily a problem of motivation, rather than an inherent pedagogical problem in online coursework. It's very hard to motivate yourself to consistently work on coursework if there are no deadlines and dropping the course just means you keep going with it sometime later. Still, I can't really explain why the SJSU courses failed as well; it sounds like students had actual deadlines, and were "required" to complete the courses to the same degree they're required to complete their regular courses. It's possible that the online tools to ask for help didn't work as well as in-person interaction, or that sitting in front of a computer doing things at random times is less motivating than actually attending lectures in person at regular times. There's one thing I'm certain of, however: it's a huge waste to have universities pay professors (who are selected for their research ability, not teaching skills) to repeatedly lecture the same material to small groups of people. A hybrid model might work best. Lectures could still be online (but possibly at fixed times to prevent procrastination), but they would be supplemented by in-person recitations, where students would meet in small groups with instructors and have the opportunity to ask questions or review particular topics, with the instructor as well as with peers. This model is still far more expensive and less accessible than online courses hoped to be, but it might actually work.

I see the point here. Attempting to put legal dogs onto this type of issue does not at all cover the scope of how society's perception pans out.

The fact that a legal system might punish someone does not in any way demotivate the behavior but merely makes it more intractable when it does happen. That someone is punished doesn't change the motivations behind the victim's name change, and other efforts.

The question still stands, for companies or institutions of victims like this: Do we want to affiliate ourselves with someone who has a love life that cannot be respected[0], that is out of line with our organization's ethos?

Punishment does not at all address this cultural problem: What is porn ?

[0]: "But the presence of Hip as a working philosophy in the sub-worlds of American life is probably due to jazz, and its knife-like entrance into culture, its subtle but so penetrating influence on an avant-garde generation—that post-war generation of adventurers who (some consciously, some by osmosis) had absorbed the lessons of disillusionment and disgust of the Twenties, the Depression, and the War. Sharing a collective disbelief in the words of men who had too much money and controlled too many things, they knew almost as powerful a disbelief in the socially monolithic ideas of the single mate, the solid family and the respectable love life."
