There may be a cost reducing technique (technology) in the way education is conducted. But it's optimizing something that's not the bottleneck.

My take. I think the main reason for increasing costs is loans. Loans that cannot be escaped through bankruptcy. Colleges can raise tuition at rates much faster than inflation because everyone has access to unlimited student loan money. They name a price, all students can access money to pay it.

One way to bring prices down is to allow prices to grow so high that people balk. Even when provided access to unlimited loan money to pay it. Waiting for this to happen doesn't require any special activism or groups though. But it might just be the actual way it plays out. A natural bubble pop.

If you don't want to sit on the sidelines and wait for things to pop naturally, you could raise awareness about loans. Try to make people balk at the prices sooner? Or try to promote a change in the law allowing bankruptcy to be an escape from loans. Once bankruptcy is introduced you will see access to money plummet sharply and college tuition prices along with it.

The longer this goes on, the more people unwittingly commit themselves into life long indentured servitude.

TOO LONG DIDN'T READ: I don't think you will successfully leverage your skills as a programmer to reduce college tuition costs. Even if you optimize a piece of the puzzle (online MOOC reducing the need for staff/land/buildings)

This is partially addressed by the article:

>Simple stick stabilized rockets work out well for small pyrotechnics, but don’t scale well. If you want bigger bangs and larger bursts in the air you need to get more payload up there. A larger rocket, with a few pounds of excitement at the front end, would require a stick 20-30 feet in length; not very practical.

En essence, rocket like designs are less stable, less predictable, and more complicated.

It is hard to have something simpler and cheaper than a ball.
> This anti-consumer behavior on behalf of companies

I strongly disagree with this. I see no way to rationalize that a company should be responsible for ensuring that counterfeit devices work correctly by releasing drivers that are tolerant of them or do not stop them from functioning. FTDI's products are the combination of their hardware with their drivers. Both are required in order to delivery functionality and reliability to meet their specifications.

Imagine your drivers are used in some sort of a critical application and a counterfeit device causes a failure that, in turn, causes harm to someone. An example might be a wired remote control for an industrial machine. It seems to met that bricking that device as soon as possible before harm is done is what we would want from a company that delivers a quality product.

Another way to put it is: Let the counterfeiters engineer a real product and be responsible for their own drivers, quality and safety.

The way to see clearly through some of these problems is to extend the definition towards extremes. Let's forget FTDI for a moment and generalize the problem to a microprocessor and a vendor-provided RTOS used to run the flight system of an airliner. This is a contrived hypothetical, forgive me for taking artistic license.

Imagine counterfeit processor make it into the supply chain. Should the avionics OS do its best to work with every possible fake or should it brick it on power-up before that potentially dangerous aircraft gets off the ground?

Another hypothetical could be one where we eliminate hardware completely. Imagine someone creates a fake Amazon, Facebook, NY Times or online brokerage site. Imagine proposing that the real companies would be anti-consumer if they created software that revealed the impostors. I could not imagine anyone who would propose they allow the fakes to continue to deceive consumers.

From my perspective this isn't anti-consumer at all. It's as pro-consumer as you can get: You work hard to ensure quality, consistency, performance and reliability.

The real anti-consumers are the counterfeit manufacturers. They, quite literally, could not care less. All they care about is tricking engineers and consumers into thinking they are designing and buying a quality product when, in reality, they might be dealing with dangerous junk.
> it still hasn't been made clear why the driver was on the highway.

This is the most interesting thing about the event. If the driver hadn't been black, even if their true (still unknown) motivations had been identical -- mental illness, for example -- the narrative would have been very different.

I run NixOS. I recently wrote a blog post about my opinions of the pros/cons: https://willghatch.net/blog/2020/06/27/nixos-the-good-the-ba...

For several years previously I ran Arch Linux on laptops, Debian on servers, and a mix of the two on various desktops. I'm generally much happier with NixOS. NixOS-style package management is the future, it's clearly better than all its competitors (I put Guix together with Nix as NixOS-style here). NixOS-style system configuration is also much nicer than most OSes, though the quality of configuration design for different components varies a lot, and I think there could be big improvements to the configuration language and APIs in future OSes that try to improve on the model (largely due to NixOS being the first system of its kind). I'm happy that Guix is also exploring this space and making some different decisions, and it's the only other OS that I would seriously consider right now. All in all, I'm very pleased with NixOS.
But maybe, like in any social network, there is a bias on what is put in front page. And if you have an interesting project, you might want to add an extra layer of complexity and use Kubernetes in order to gain more visibility.

This makes me so sad.

I’m in no way excusing the driver (who will undoubtedly receive punishment), but after 19 consecutive days of walking onto the freeway, and the city effectively supporting it, some kind of accident was bound to happen at some point. It’s terrible, but I hope there’s some lessons to be learned (the city seems to have learned something, as they stopped allowing the nightly freeway protests).
The great news for business owners in Seattle’s CHOP zone is that they get to pay for two protection services: one is from the city which is nonexistent. The other is from the private service.

The main issue with -static is that glibc is a massive PITA that hates being statically linked due to its reliance on dlopen() for locale and NSS management. It's therefore not recommended linking it anything but dynamically and afaik there is no "pick all static but libc" option in Clang or GCC. The other option is using an Alpine chroot and statically link using musl, but there are lots of compatibility issues with certain programs that massively abuse of GNUisms (i.e see anything ever written by Pöttering) and not every library has a .a available in the package manager, so you must compile them also.

Yes, someone driving onto a highway via an off ramp is bound to lead to an accident.
> I strongly disagree with this. I see no way to rationalize that a company should be responsible for ensuring that counterfeit devices work correctly

They destroyed devices that worked perfectly well, but maybe (or maybe not) had a fake FTDI branding on a chip inside the device.

Even the manufacturer may have been a victim of commingled inventory. For this reason I stopped buying anything with FTDI in it, because I didn't want to take the chance it would be bricked because the smalltime seller on Tindie.com bought from a bad supplier.

I would hate to think what you would have Apple do to Hackintosh hardware.
Yeah, if you pay taxes and are within the CHOP zones, do you get a refund because you didn't get the law enforcement services you paid for? Completely ridiculous that this CHOP thing has been allowed to continue for so long. No other group could simply seize control of part of a city and behave like a gang.
The bagging policy is ridiculous because it has about as much to do with safety as the TSA. It's theatre. That it's theatre is apparent from the fact that the store isn't operating with a skeleton crew (which would be a meaningful distancing measure.) If they haven't bothered to minimize the number of employees in close proximity to customers, why should I believe any of their other measures are rationally motivated?

Even if you think that context isn't relevant, the premise of covid spread through surface contamination is still dubious. And even if that risk were credible, I assert that banning reusable bags would still be a dubious measure. Instead of using a grocery bag touched only by myself, they'd have me using grocery bags that have been touched by employees. Employees who've also touched my food, which I touched before them. Food which was probably touched by other customers before me. If surface contamination is a serious concern, the entire premise of a self-service grocery store is fucked and they should stop letting customers inside the store (self-service grocery stores are a 20th century invention; alternative schemes exist. Notably, self-service grocery stores weren't common until years after the Spanish Flu...) Since they haven't done that, it's impossible for me to take their bag ban seriously.

> One spring day in 2005, a yellow school bus carrying six passengers turned onto a freshly paved driveway seven miles southeast of downtown Des Moines, Iowa. Passing beneath a tunnel of cottonwood trees listing in the wind, it rumbled past a life-size sculpture of an elephant before pulling up beside a new building. Two glass towers loomed over the 13,000-square-foot laboratory, framed on three sides by a glittering blue lake. Sunlight glanced off the western tower, scrunching the faces pressed to the windows of the bus.

This very much applies to the de-facto economic system in Russia. Not on the parking meter level, but more that you cannot run a moderately-sized business without being a part of a corrupt network originating from the early post-USSR mafia.

The biggest trouble with this model is the lack of long-term predictability. Sure, you can pay your protection money and operate your business today, but the next day your "supervisor" gets on bad terms with his superiors and gets replaced. Their successor may simply not like you (or have their own protege to take your place) and then you're basically screwed. Your business gets raided, your family is taken hostage, you will be happy if you're left alive after basically donating your share to somebody who had better connections.

As a result, nobody wants to do long-term investments. Business that cannot be promptly liquidated is not not worth the hassle. Assets that cannot be transferred outside of Russian jurisdiction in case shit hits the fan are liabilities. So the economy boils down to extremely corrupt oil/gas companies owned by people from Vladimir Putin's personal network, and rather rare mom-and-pop shops that sort of fly under the radar until they don't.

I hope this model isn't coming to the West, since it's simply incompatible with economic prosperity.
> I strongly disagree with this. I see no way to rationalize that a company should be responsible for ensuring that counterfeit devices work correctly by releasing drivers that are tolerant of them or do not stop them from functioning.

There's a difference between not taking steps to ensure counterfeit devices function, and purposefully causing hardware to fail on a remote system. For example, I'm pretty sure purposefully causing the problem is illegal, if the user didn't request it, as it seems the same as hacking to me.

> Imagine counterfeit processor make it into the supply chain. Should the avionics OS do its best to work with every possible fake or should it brick it on power-up before that potentially dangerous aircraft gets off the ground?

Refusing to function is acceptable. Bricking the hardware is not.
God so much this. Manual retweets didn't really work like the feature Twitter implemented do and they had drastically different effects on content spread. Quote tweets (which were also emergent before rts even became a feature) are actually closer in those terms.

But because the button is right there the more useful emergent version died completely off.
That's true in an analog design, I recently took apart a generic computer power supply that failed and noticed it used NTC thermistors. In a hobbyist kit I purchased that came with with various cheap sensors, the temperature one has a Dallas 18B20 on a board to be interfaced with an Arduino. It's probable that some people would just duplicate exactly what they used on a quick-and-dirty design to be deployed on a small scale.
First, there's no reason to expect that your immune response will fade in 3-5 months. The concentration of antibodies in the blood does decrease with time, but immunity to the original SARS lasted at least for years[1]. For a virus that was only discovered X months ago, it's impossible to demonstrate that immunity lasts longer than X months; but it seems pretty likely to me.

Second, there's no firm evidence that anyone has ever been reinfected yet[2], but there's no specific reason to believe that your symptoms would be worse the second time. Antibody-dependent enhancement was observed with some vaccine candidates for the original SARS[3], but so far the SARS-CoV-2 vaccine candidates haven't shown that. In the other direction, I've seen speculation that some modern common colds are the faint echoes of ancient pandemics, and SARS-CoV-2 would eventually end up similar if uncontrolled, with immunity acquired initially in childhood (where the IFR is not zero but extremely small, 16 per million[4]) and reinforced with mild infections throughout one's life.

2. The evidence for reinfection is that some people have tested positive then negative then positive by PCR, and perhaps their symptoms got worse then better then worse again too; but since the PCR test has a significant false negative rate, it might just be one long illness.

I've got one genuine one that I bought from Sparkfun near the end of 2015 and 10 more I got from Amazon in the middle of last year.

I haven't gotten around to doing anything with the 10, but the genuine one has been hooked up to an RPi for a while, which is controlling a space heater.

That was still using a solderless breadboard, so it was an easy matter to swap in the 10 one by one and check if they were genuine. As was probably to be expected, they are all counterfeit.

They all seemed to be fairly consistent with each other and with the genuine one, although it turns out that these things are really sensitive to body heat--just holding one pinched between two fingers while slightly spreading the leads to fit the breadboard would heat it up 2-3 C. This made comparing different ones a bit confusing.

The genuine one seems to cool back down to room temperature noticeably faster than the counterfeits. I wonder if the genuine ones take more care to ensure that the die is not too insulated from the outside world so it will be more responsive?

Anyway, since I'm still using a solderless breadboard, and then things are designed to chain, it was not hard to rig it up so all 11 are hooked up at once [1]. (And yes, the resister is hooked up correctly. It is just a really bad angle in the photo that makes it look like it is off by one).

I've got a program running now that checks them all periodically and logs all the readings. Here are results after it has been running about 20 minutes:

22.437 [22.375, 22.25, 22.187, 22.312, 22.375, 22.187, 22.25, 22.25, 22.375, 22.25]

The first one is the genuine one, and the array are the counterfeits.
