So, last time this was posted I commented that I was interested, but couldn't use this at work because of the GPL license.

Since then I implemented my own M:N userspace:kernel threading library (which is what lthread boils down to) based on Russ Cox's BSD-licensed libtask. You know what I found?

1) Many libc routines require a surprisingly large amount of stack. 64kiB was the smallest power of 2 I could find where I wouldn't overflow the stack somewhere in a libc call. (This isn't a problem with stack-copying, but it is a problem if you have dedicated per-lthread stacks).

2) It was slow! Just dropping the M:N library and using blocking network I/O with 200+ kernel pthreads was vastly faster.

3) Many pthread-functions get very, very confused if they are used from different pthreads (same logical "lthread"). (This happens when a userspace scheduler swap happens between matching operations.) For example, pthread mutexes don't like to be locked in one pthread and unlocked in another pthread (same "lthread"). I ran into other things that match this category, but can't remember them off of the top of my head.

I ended up scrapping it and just using a pool of kernel pthreads. It works, the code is pretty clear (blocking IO! whatever, man), and it's fast enough.

Edit: By "fast enough", I mean "can fill 2x 1Gbit pipes from disk" (without any perf-focused work thus far).

Be patronizing I left a high-paying job after upper management installed a smug, platitudinous director over my group. I disagree that people become what you expect of them. I would not become an imbecile because my boss believed that everyone else was an imbecile. There's no reason to lose one's dignity.
When my wife was at a very large company, her good managers [0] did these things:

-- make sure the programming team understands the customer's priorities, goals, timelines, etc.

-- pay attention to the task breakdown, making sure that all of the programmers know what pieces to work on, and making sure that important pieces don't get overlooked

-- make sure the programming team has the resources they need. Fight with upper management, procurement, HR, or whoever else in order to get the necessary equipment and personnel.

[0] This is not always a single person with the "manager" title. Sometimes it's a "team lead", or multiple people with multiple titles.
I've been working on a sculpture project[1] based on cellular automaton for the past two semesters. It's not exactly conway's game of life as I'm mostly focused on polygonal cells. Hardware wise it's mostly just LEDs with shift registers and an ATtiny85 but the code[2] might be interesting to some, in particular dealing with figuring out what cells are and aren't neighbors when you have an ambiguous layout. I've also put together an Android simulator[3] I use for exploring ideas that defines designs using JSON but I've put a lot less work into it.

I've been playing with Julia a bit lately, but I haven't had any good reasons to write real code in it yet. I've got to say, a useful Python compatibility layer between the two languages would be awesome. Being able to call SciPy libraries from Julia would make it a lot more interesting to start writing Julia code.
Cool that he took it to the extreme and actually created a font based on his results ('Averia': http://openfontlibrary.org/font/averia/ )
Great point! :-)
Older versions required calling emergency services, newer versions do not.

And they aren't illegal -- many first world countries require that phone companies unlock your phone if you request it, and of those that don't, I don't know of any where the hardware is illegal. They are openly sold in stores in the USA, which I think is one of the most restrictive countries about such things. Calling emergency services for non-emergency purposes is not usually legal, but that doesn't seem to be what you are saying.

Well, actually it's $1bn for an app that shares pictures. It's only worth that because people use it. 40 million people according to recent reports.

If you want resources spent on more serious stuff, you'll have to start by getting the general public to spend their time more seriously, because that's the root problem.

The Man Who Quit Money
A business founder might know how to code but at the end of the day, he/she is less of a coder than that "technical founder". Same way that the technical coder could go out and sell product but the business founder is probably the one better able to do it. It's about respecting what each founder brings to the table and using that to move forward. If they can deliver value, there's no reason to waste any time on proving who is more important.

Best bosses: Usually self-describe themselves as "meat shields" for their troops. Ask "How can I help you do your job?" instead of "Why isn't that done yet?" Understands the creative process.

Worst bosses: Ditherers, or opaque and random ciphers. Never present. Jerk you from one task to another. Surprise you with bad reviews. Unwilling to pay for good tools ("What's wrong with Notepad?") Sees you as a fungible cog or chess piece to be moved around. Often non-technical, or "used to be technical" in an ossified region of the industry (e.g., large aerospace firm). Uses Scrum as a platform for micromanaging.

[I made a decision 25 years ago never to be a manager. I recently had the opportunity to try it out again for a summer, and it sucked just as hard as I remembered. I am an engineer, and I work with people in a far different way than good managers do.]
This worked out beautifully. I hope we see a lot of new electronics projects built like this in the next few months.

His choice to pot the electronics in transparent (apparently polyester) resin reminded me of this unfinished design provocation of mine, "The Egg of the Phoenix: a computational time capsule": http://www.canonical.org/~kragen/eotf/

Specifically, I was thinking that potting solar-powered electronics in transparent resin would be a good way to ruggedize them, so that your electronics might have a chance to keep working for decades or centuries.
I've been at more than my fair share of establishments. The boss that stands out as the worst, hands down, had two traits that stood out:

1. An alpha personality that could admit no wrong.
2. A failure to leverage his senior people for their abilities, everyone was treated as a contractor and told what/how to do it.

This was a startup and the behavior basically resulted in a couple of us leaving. There were other bits of the startup that were chaotic (and could be attributed to a fast/changing environment), but this individuals behavior sealed the deal for a couple of us.

Personally, I've had to manage a bit here and there. When it is a small company/team, I really prefer to understand everyone's strengths and weaknesses. Cater to the strengths, learn where I can, and try and fill in the weaknesses with other's strengths. Even with many years of experience, there is still something I can learn from most people (rockstar, average, etc.)

well, one of the technical challenges in medicine is how to share medical imaging between different hospitals and doctors. the current "PACS" systems that do that suck.

How would you render trees or (big) matrices? Recursive functions? Infinite lists?

You don't. I think the Light Table author is naive here. Instead, you let the programmer rewind the stack at will.

I'm upset because the method of discussion here seems to revolve around tainting the credulity of the author ("That you'd make such an argument indicates you aren't in command of all the facts")

The facts in question have to do with things I've seen implemented. Your argument is an indication you aren't aware of the same. That's not tainting your credulity. I'm questioning if you have all the facts.

By the way, I feel that those who have to play the "If you ever get someone upset, you've struck gold!"-card, should listen to some more gentlemen talk about syllogisms.

You are the one who is upset. You are also incorrect about what you purport to be upset about. (My intentions in pointing out certain facts and their implications.) Please process this data.

I think it was a great investment and great for them for the transparency. For those that criticize how much money was in so short period of time. You are probably in the wrong industry. I'm sure nobody feel bad for when somebody else do a bad investment. Thinks can go in both ways.

Thanks a ton for posting this - I didn't realize I was looking for a Bootstrap replacement 'til I found this thread, but this feels cleaner in a lot of very nice ways.
I took your comment to heart and removed most of the comments in the source. I found the video inspiring (and infuriating) - just more proof that I'm a long way from unlearning my OO design tendencies. To start, I made the Neighborhood class a function instead. Thanks for sharing.
You're comparing apples and oranges.

Cancer research is a gamble: You spend years of your life pipetting liquids in the hope that you'll discover something new that improves upon the current standard methods of treating cancer. The equivalent in CS is, well, CS research: You spend years of your life poring over journals in the hope that you'll discover something that dramatically improves the standards of computing.

Like a lot of research, these are highly worthwhile activities but they aren't big business. That's why, if you want to see more of them, the bottleneck isn't finding the talent: It's the funding, which generally comes from taxpayers. (I assure you from very personal experience that there is a large and consistent oversupply of people who would be willing to conduct cancer research, or any other kind of research, so long as the funding is there.)

Whereas sending cat pictures is not a gamble. It is an established business. It reliably, demonstrably, and very inexpensively improves the lives of tens of millions of average people, to the extent that it and similar businesses are consistently profitable ($355 million earned at Facebook on revenues of $1.2 billion, for example).

And cancer treatment - doing more of what we already know how to do to treat cancer - is likewise not a gamble but a business, which is presumably why it's a huge and growing sector of the economy that dwarfs Facebook and everything else that's fun – $128 billion per year in the USA alone:

http://www.cancer.gov/aboutnci/servingpeople/cancer-statisti...

For comparison: Global advertising revenue is estimated at around $420 billion per year:

http://www.reuters.com/article/2010/12/05/magnaglobal-idUSN0...

So given that the USA is only 309 million people out of seven billion, we can guess with some confidence that the world spends more on cancer treatment than on advertising of any sort, let alone on the tiny percentage of ads that suffice to pay for all the cat pictures that any cat lover could want.
I don't really understand the structure of the different departments teaching computer science and engineering at UF, but it certainly sounds like a bit of a mess and over-due for a reorganization.

Even Georgia Tech, the first school with a College of Computing, still has a split with Computer Engineering still part of the College of Engineering but traditional Computer Science and everything else in the College of Computing. USF (Tampa) has both Computer Science and Computer Engineering in a single department within the College of Engineering, which seems to me to be about the most efficient structure. UCF (Orlando) had a Computer Science department in the College of Arts and Sciences and a Computer Engineering department in the College of Engineering but merged them together into one school a few years ago.
I laughed out loud at this. Faculty can run good research programs and be decent teachers but if they're only measured on research grant dollars, completed graduate degrees, and publications, why spend any extra effort on teaching undergrads?
Buying and selling gold
This is really interesting. I think the result is very attractive and readable. Yet it's also difficult to recall. It reminds me of a face built of averages (http://www.uni-regensburg.de/Fakultaeten/phil_Fak_II/Psychol...) - attractive, but somehow lacking in character.

Great work in any case.
Especially after you factor in taxation. I live in Toronto, which is probably the second most expensive city in Canada, and I would rather earn 35k in northern Ontario than 60k here, even if the taxes were equal but after the taxes are taken into account it gets all the more crazy.

The only thing stopping me from moving to a little cabin in the woods is that I like to spend time around intelligent people interested in the same things I am, which is impossible in the boonies.

There is actually some pretty good software that does this - it's just not very common because cable companies control the DVRs and they have to agree to rules set by the networks.

I see the risk. However, after 4 years at the company, I felt I should have been trusted. Here's the rest of this particular story:

A year later, I said screw it and worked on it anyway, for 2 weeks (manager was out of town). It was an internal tool. It became the most popular internal tool in the office (95% of people have it open in a browser tab all day). At one point, the founder checked it out and said "I love [name of tool]!". Vindication. I left the company after that, and they use the tool to this day.
Remember that in the case of the gulf oil spil, Corexit was used in a way that it wasn't ever specifically engineered for (based on their own datasheets for 9500). Instead, it was directly inserted into the stream just a meter or so above the wellhead, underwater. There are videos of this from the ROV streams, and corroborated by other sources (eg NYT: http://green.blogs.nytimes.com/2011/08/26/impact-of-gulf-spi... Wiki: http://en.wikipedia.org/wiki/Deepwater_Horizon_oil_spill#Use... )

The result was formation of these subsurface plumes that the author talks about.
Argh!!! This is precisely the problem when you give developers a designers' problems. It is not possible to engineer your way around every problem.

In this specific case, the font is blurry, unattractive, and lacking any character. It looks like someone tried to autotraced a photocopied fax of a carbon copy.

It's an interesting experiment to be sure – but this is not, in anyway, a solution to … anything.

How to Multiply two 3-digit numbers together mentally in just one line
http://mathema-tricks.blogspot.com/2012/04/multiplying-two-3-digit-numbers.html
Its too early in the day to get into these many details. The primary focus must now be

a. Set of goals.
b. Fastest way to get to the set of goals.
c. Building a community and getting them to contribute.

Anything else and we would be prematurely optimizing. And falling through a unproductive rabit hole.

The primary focus at this time must be to worry about a basic usable product with a extensible mechanism and growing a community. The faster you get something out, the more awesome it will be. After this kind of a built up, not having a quick release or a bad release will disappoint a lot of people.

Will be nice to see something in the next 6 months.

Heh interesting idea, but I'm pretty sure the kid could be convinced to sell for $5000, probably much less - there aren't many kids out there that would scoff at multiple years' worth of allowance and lawn mowing money just falling in their lap. I think a market composed of people actually using the resource can set fair market pricing without the involvement of speculators. Domain speculators/squatters literally only drive the price of doing real things up.

No, they're called "Tri-Gate" transistors if you want to nit. FinFET is an industry term, not one Intel uses for this particular process. Both/either are examples of 3D transistor structure, so the linked article isn't wrong.

The author doesn't imply that it's attractive or useful, just that it's the average of all the fonts on this system. He even jokes that the name meaning "mechanical breakdown or damage" is somehow appropriate.

This is, in some ways, the solution to... visualizing the average of all the fonts on this system.

(Although, I think the result is attractive. Probably not very readable, or useful other than for some sort of logotype. Almost makes me think of letters made out of the balls in world of goo.)
