Which 20+ stories? The one where a journalist with financial ties to a competitor tried to bait an Uber exec into a hypothetical conversation and then took lines out of context (others at that dinner party said effectively the same thing). Or do you mean the one where they're giving private contractors new opportunities?

None of the good things that Uber are doing came from uber. Those were all things that non-biased third parties said. Are any of them not true? Is Uber not actually creating more jobs next year than the sum of all startups combined? Are they not saving lives from DUIs? Are they not (and have they not) done a significant amount for charity from their on-demand charity events?

Maybe I'm missing something here. I'm open to a different take on those points. Those appear to be significant points in favor of Uber. I'm open to a conversation on the pros/cons though. Maybe you can change my mind.
The concern with lobbying is not so much "money for votes," but that most people are powerless, so they have no one lobbying for them. The concern, in other words, is that lawmakers don't get to consider or even understand the narrative of the people they're supposedly representing.
"mpg123 has no controls..."

It does with the -C option:

Enable terminal control keys. By default use 's' or the space bar to
stop/restart (pause, unpause) playback, 'f' to jump forward to the next
song, 'b' to jump back to the beginning of the song, ',' to rewind, '.'
to fast forward, and 'q' to quit. Type 'h' for a full list of
available controls.

I think all these sites (treehouse, code academy etc) are going to be hit with class action lawsuits for implying that their app/whatever will make you proficient at coding, and even land you a job. There are no shortcuts to becoming good at coding. It takes much longer and is much harder than these sites make it seem.

Recently, I was researching about moving back to India and continue working for my employer from there and get paid in USD. In theory, this should be possible. My employers might agree to this (they do it to other colleagues of mine in different countries). However, the taxation laws in India are not straight forward around this. You can explore to see if this is a legit option for you. If you have a solid profile as in open source contributions and you can pull off working remotely (definitely not easy), this is the most lucrative option for you. Trust me, living in USA is not what it used to be. The whole political climate with so many wars, government snooping, highly variant economy and things like Ferguson make it less attractive. If I were considering a move today, I'd definitely think 10 times. Plus the stress levels here are amazingly high. Everyone seems to be lost in their "careers". Of course there are positive aspects of living here. It's definitely a trade off like anywhere else. Good luck. I hope to bump into you someday and hear your story of sailing the boat ;).

I don't get this kind of reasoning. Since when is $100K+ a year, plus bonus and stocks, "very little money"?

I'm a foreign STEM worker myself, currently on an H-1B visa. I have a very decent life here in the US, much better than I had it in Brazil. Back there both my wife and I worked and we lived at a quite lower standard than we live here. Now I'm currently the only one working and we live in a way nicer looking place, have a car we could never afford there and we're able to save some good money and still get to travel a few times a year.

So really, where is the "very little money"? A lot of other people share stories similar to mine and are doing pretty well too. And by the way, we're in our 20s and I was a college hire, so the good situation is not really due to having experience and being hired into a higher position.

This is a good example of why the focus on developing magic pills that aim to curb obesity is so silly[1].

Body composition and strength are just as important, if not more important, than weight, especially as one ages. The reason this is ignored is that there's only so much you can do to significantly improve your body composition and strength without exercise and healthy eating.

> Nonetheless, the maintenance of adequate muscle mass, strength, and metabolic function has rarely, if ever, been targeted as a relevant endpoint of recommendations for dietary intake.

It's kind of sad that the "official" recommendations basically ignore what even the most inexperienced personal trainer could tell you.

Personal anecdote here, but I don't look like I belong in the loop for anything other than begging. I'm an overweight white male with long, typically unkempt hair, an untrimmed beard, and a pair of shoes that are dirty and have an obvious rip in the front. My jacket is dirty and often covered in mud / dust / etc. Most of the beggars I pass on my walk into work look far better off than I do.

I have never felt as though I couldn't get a cab in Chicago. Not during rush hour in the loop (when I could easily be passed for a well-off guy in a suit thirty paces down the line). Not at 3am when the bar is closing and there exists a line of upper middle class to upper class drunks failing over themselves for a cab. Not on Michigan at lunch. Endless opportunities to not pick up a ragged homeless guy, and money always plays.

Edit: Have a beard, unfortunately not an ursine.

You shouldn't blame him. The truth is that Emacs does a great job at hiding its potential from users. Editors like Atom are ultimately much less powerful but they make it easy to discover and use the features that they provide. When I started using Emacs (after a decade of Vim), it took me two years to make myself fully feel at home in Emacs. Part of the reason was that you can't really use Emacs to its fullest without learning a good deal of Elisp. This is the part were other editors do much better.
This should run most of the existing Ubuntu and Android images without any hassle. Having owned an ODROID-U2 for a long while now, I can tell you that these things run Ubuntu 14.04 like a dream (except for the lack of OpenGL - you only get ES) and Android works great:

It's one more tool for achieving reuseability without sacrificing performance. The size and weight of an air-breathing system will be lower due to greatly increased Isp of the 1st stage, the largest stage by mass.

A smaller 1st stage fuel tank might mean that heat-shielding or higher temp materials is more of an option, which means you can raise the 1st stage separation velocity closer to what is "optimum" in the rocket sense and still recover the 1st stage. This puts the 2nd stage closer to its natural optimum design point.

Overall size might not be a show-stopping problem now, but for building space colonies or Mars missions, overall vehicle size does eventually become concerning. Think of trying to build a jig to friction-stir weld a 180m long, 14m wide fuel tank. It's cool but also a bit of a distraction to have to build and handle everything at unusual scale.

It would be super cool to see big packs of ten F414's at the base separate off, curve back towards the launch site, flip out some wings, and then cobra into a vertical landing. GE should step in right now to have the perfect platform to develop ceramic parts without the same service life requirements as aviation gas turbines.

(I work at Khan Academy.)

> The Khan Academy developers have devoted a lot of thought to hope to computerize problems rather than exercises, and they are still working on building new problem types for the mathematics lessons. I'm actually quite impressed with some of the problem types that show up in more advanced mathematics lessons on Khan Academy that go beyond the eighth grade level implied by current United States curriculum standards.

Thank you.

> Common Core, and good mathematics curricular around the world, expect reasoning and explanation from pupils in mathematics lessons already at elementary school age. That currently is indeed difficult to automate.

This is definitely true. By no means is Khan Academy a complete solution for mathematics instruction, nor is it likely to become one in the next few years. Our site should ideally be used alongside other materials that test reasoning and explanation in a non-automated way, as well as projects that allow students to apply their knowledge. We have early experiments that take a much more interactive approach to teaching certain concepts and encourage more experimentation, but we're probably years away from developing them into a shipping product.

> The author's comments on development of Smarter Balanced Assessment (SBC) as a new platform of online mathematics instruction is of course especially interesting. I will be curious to see how this program continues to develop, and I would be glad to hear from developers of that program in this thread too.

If I'm not mistaken, many of the SBAC problems (especially free-response ones) are hand-graded, which can work if you charge for each test taken, but can't work for us when we have millions of problems done every day, all graded automatically. That said, we're exploring strategies like peer grading in other subject areas (particularly our programming curriculum) and would be excited to bring them to math as well.
KDE will only fully support it in Plasma 5.0. As of now it's somewhat messy and requires lot's of manual tweaks besides changing the DPI.

See https://community.kde.org/KDE/High-dpi_issues

However one should be careful when getting monitors with such huge resolution since they put more requirements on the GPU. For example if you want to play games in native, it will require dual GPU at least which is a very pricey overkill otherwise. Current video cards don't cope with such resolution well yet. That besides the fact that such monitors are very expensive on their own.

Also, ergonomics wise, for me personally 24-27" is a sweep spot. Anything larger than that becomes uncomfortable to use unless you place it in some distance.
I think a lot of what we call simple programming today will just be expected knowledge for most people in a short amount of time. Doing Scratch exercises or writing a macro will not make me a future person a programmer in the same way doing some simple math does not make me today a mathematician.

I'm certainly not saying these behaviors are only due to conspiracy, as your response seems to be addressing. What I am saying is that the most effective and stealthy way of steering and disrupting conversation is to encourage these natural behaviors, and simultaneously calling out the organic infighting. Your previous assertion that discourse control would manifest as simple for/against is itself a straw man.

I'll own that my comment is a handywavy journey of rough assumptions, not an open and shut logical course. This is the case with any heuristic, and it's necessary navigate the unknowable (without waiting decades to get lucky for a leak to reveal specifics, at which point the method is ancient history anyway).

The way I see it, in 2014 the onus of proof is on someone who wishes to assert that discussions aren't being manipulated - if not by USG "itself", then by private companies looking out for their own interests. The only mechanism that would prevent corporate self-interest from evolving to this is individuals' morals, and given what we know about moral plasticity I don't see how that's any more than wishful thinking.

You should check the ODROID forum for newer graphics drivers. The bleeding edge versions are released every now and then as separate binaries/images.
Reminds me of sound-sampling on the C64 via the tape port: The C64 tape port is connected to the GPIO pins on the 6510 CPU. You get 1 bit amplitude data, at roughly whatever spedd you manage to sample the register.

The problem there of course is that you're dealing with a 1MHz CPU, and 64K memory, and for real-time sampling you need to make tradeoffs between sacrificing sample rate for cycles to somewhat compress the data vs. running out of RAM in seconds.

For playback, it's equally primitive: With some settings, flipping the volume to max and down creates a sufficient click that doing that for 1, and keeping it off for 0 gives you recognisable sampled music output.

It's really quite amazing how low bitrate you can get to and still have recognisable music.

If you do pre-processing you can get quite tolerable, substantially longer samples (if you do lots of pre-processing you can end up with this: https://www.youtube.com/watch?v=D6MSbdUMFZ4 )
Aggregate deflation is not a positive for an economy. It's nice that some sectors are more accessile than previous centuries, esp. food and clothing, but that doesn't mean that deflation in every sector indicates forward momentum.

To be fair, low refresh rates are much more bearable on LCD screens they used to be on CRTs, since there is no flicker.

(This is assuming the task at hand doesn't require a high refresh rate of course - a reflex based game like an FPS would be a no-go)
You might not be trolling, but you sound willfully ignorant.
No, because the actual phrase was "normal circle of a family and its social acquaintances". The people you work with are not part of your family's normal social aquaintances (ok, a handful of them may be).

It's pretty clear that this phrase means your family and usual circle of friends who visit your family (semi-) regularly, i.e. normally. It does not mean the office party.

Ask yourself this: if you quit your job, would your collegues still be normal aquaintances of your family? If not, then they are not social acquaintances.
Thanks a lot! I will look into that very soon, you might have saved me a headache!

Good. You seem to favor form over functionality, nothing wrong with that. Emacs is the complete opposite of that.
Yeah, but that's fine. Tptacek is not a sock-puppet, exactly because he's one guy with strong views. Yes, he has a lot of power here, and uses it to shape the discussion, but that's what we want! If we decide we don't like what he's doing, we can down-vote him to oblivion, or just ignore him.

The problem is when one person has 1500 accounts, and just uses them to direct the discussion, without actually contributing to it.
Even before eyesight problems, it's recommended to have a screen at least at 65cm to avoid forcing eyes to accomodate, which is more or less our arm's length. iPhones are a pleague for eyesight, tablets are slightly better (except that we read them longer) and a huge screen, far away in the distance of the desktop is certainly a good solution.
Bush wrote in his memoirs about how advanced interrogation wasn't really torture. Cheney says that both he and Bush knew.

There is a huge difference between torture and killing people with drone strikes abroad after they joined al Qaeda. Once captured, a person is no longer a solider or a combatant.

But some American citizen who is fighting for al Qaeda? He is a soldier.

The DOJ would say they do give him due process, but I think their definition is bullshit and can be dangerous.

But I don't think an enemy solider gets any due process. We didn't read the Confederate Army their rights at Gettysberg. We just shot at them. I just don't think someone at war and at large gets due process.

That seems better. However, the return values were almost too dark to read while there's daylight, and I got only eight commands into it before I found an error. (mod -3 5) returns -3. I don't know if that error is just in this implementation, or in many versions of Common Lisp, but a quick search shows there are versions of Common Lisp where mod is implemented correctly. (In mathematics, -3 = 2 modulo 5, or equivalently (-3 mod 5) = 2. Even Python knows that -3 % 5 == 2, where '%' is Python's modulus operator.)

"The trade-off with upgrading the engine to produce 26,400lb-thrust is a considerable hike in maintenance costs. Running the F414 EDE at the higher thrust setting reduces turbine life to 2,000h, Caplan says. This is just one-third of the current 6,000h interval."

"GE also has the option of switching to a more heat-resistant material to make the blades. The company is considering designing the first-stage turbine blades of the GE9X with silicon carbide-based ceramic matrix composites (CMC), which are lighter and more heat-resistant than metal. Indeed, the company tested CMCs in the low-pressure turbine of the F414-GE-400 for a 2011 demonstration."

Turbines designed for rocket assist need to live <100hrs to service 200 launches. GE has basically already said they can push the engine to > 11:1 T:W, not including the advantages of ceramics or LNG combustors, which they also know how to make plenty of for utility gas turbines.

Worse is better is about much much more than exposing versus not exposing implementation details.

Exposing implementation details is also not quite the same thing as a leaky abstraction (although they can coincide). eqv? can be both, if you regard "cons" as an abstraction of a mathematical pair. OTOH, if you regard cons as allocating a mutable pair object, then it is neither.

Providing a function to trigger garbage collection is exposing an implementation detail, but not leaking abstraction.

It's harder to come up with examples of leaky abstractions that don't in some sense expose implementation details. I'm not sure they exist.
