My entire family are teachers (Mum, Dad, Sister, Brother), and have all had to deal with this to varying degrees, and have had it consume their lives at various times. My brother has the best work-life balance of any teacher I have ever met, and I think his approach is brilliant.

Teaching is one of those careers where the expectation is on the teacher to endlessly do more and work harder, "For the kids", and if you keep doing it, you'll work more and harder forever, endlessly.

My brother does a fantastic job, and works very hard for his students. What he does though, is walk out at 4pm and NEVER does work at home. He doesn't check his emails, he doesn't grade work and maybe only once or twice in five years has he done a lesson plan outside 8am-4pm.

If parent emails, or meetings, or "school paperwork" or whatever queue up he just makes it infinitely clear that he must choose between doing the best job for his students, or spend time with the parents or at school meetings. He does do thing pro-actively like call parents if need-be, but he does not spend hours of his personal time dealing with "helicopter parents" or stupid school meeting requirements.

It requires the right balance of "push back", but it can work very well when done correctly.

FWIW, he has quickly been promoted to the head of maths and had a real shot at a "leading teacher" position, so obviously he's very good and the entire school-body agrees.
The Chicago State St. experiment was not a good pedestrian zone. It was more like a smelly bus depot. Chicago has more than enough density to make a good ped zone work. But this is 'murica, which was built by the pilgrims for cars, not walking.
You might appreciate the Battle Box format:

https://www.channelfireball.com/articles/stark-reality-battl...

> Battle Box creates a scenario where almost every game of Magic is a good game of Magic. Sometimes you will lose, and if the cards had come in a different order you would have won. You still draw a random card every turn. However, if you wanted to play around what your opponent has and increase your chances of winning, you will be able to. Cards are roughly the same power level, and no one ever gets mana screwed or flooded, so the vast majority of games come down to the decisions you make.
I think Citizens United vs FEC [1] will be looked at by history as the real turning point (to decline) of the US federal republic.

Times square is basically just a tourist trap and not representative of a commercial zone that serves the local residential population. Locals are only there because of the transit access.
Your proposed remedy is for the shell to insert something different than what the user inputs. That is much more surprising. No program works that way.
Ah, timing other shell functions is a use case I hadn't considered. Yes, then you're out of luck I suppose.
Yes, Warchief?

Great game, can't recommend it enough. My grades took a hit too, but it was worth it.
What's interesting is that normally, USAA (and other banks that tend to cater to government employees) will offer 0% APR loans to those who are impacted by this.

There have been quite a few reports of USAA not offering loans to those who are affected by this -- and other credit unions (NFCU) only offering $1000 as a quick loan...

If the banks don't want to deal with the risk of this until the shutdown is over, this makes me believe that the shutdown will last a while.

Interestingly enough, Congresspeople's staff are not getting paid during this break as well -- but the congressfolks are.
Oh, thanks for finding this because I was curious about checking out the code (that's why I found the broken link after all). I did a quick google search but wasn't able to come up with anything.
Take a look at the planform of the airplane in the paper (figure 2). The wing is moved so far back, it is in the position the horizontal stabilizer is normally found. There it provides enough stability to overwhelm the little surface at the front.
Haha, I just finished quitting my job teaching high school computer science today.

I went from private tutoring CS to teaching in an afterschool program to this because I really enjoyed helping students break through conceptual blocks and mental ones.

The work is emotionally exhausting but satisfying. Only recently have I wondered whether or not this was the right thing to do instead of going to industry(maybe it's because a lot of my interviewers have been asking me that exact question) but it seems blatant now that my friends are senior engineers who have almost infinite job opportunities.

The real crux of it is that teachers get put into this triangle of pressures between students, administration, and their parents which almost takes away all agency from the job. I got so tired of getting put into difficult situations that were almost always juggling acts.

At the end of the day, if you want to fix anything as a teacher it's almost like going against an institution. You risk your pension, your 401k, or maybe just your potential future in industry for what?

I wasn't in it for the money and I would imagine most teachers aren't either... but what happens when your hands are too tied to actually teach?

sigh maybe I could've done everyone justice if I had some tech money to fall back on.
I have not encoded using using IoT devices, this is good to know. Thanks for clarifying that!

How many people got involved in that conversation? At least 3 different support people. And neither had a direct response to the guy. This corporate jargon is just painful to read and companies like Amazon should know better.
One thing I can say about copper is that it is noisy.

We are running FPGAs (with NICs) and were getting lots of packet errors over the copper cable SFP cables. Turns out, we either needed to write out noise cleanup logic into the FPGA, or add in a noise cleanup module which would add an extra 50ns to packet processing to the FPGA. Simple solution was to convert to fiber and the noise and errors all went away.

I'd say if audiophiles truly want unmolested electricity, they ought to use optical fiber for as much of the run as possible.
Sure. Thanks, I fixed it
Orwell is different though. It has multiple endings, you can possibly fail to come at the right conclusions at certain points which change the story dramatically, and you have to put in time and effort to actually find certain facts to get a good ending.
fluid-coupling automatics do have an advantage here, as they can essentially creep at any speed without causing undue stress to any of the vehicle's components, although you would need to use the brakes to go really slow.

when driving through complicated areas with lots of pedestrians (eg, parking lots), I usually travel at the lowest speed in 1st gear that puts the engine in a happy RPM range (as low as ~1200 in my car, maybe 1500 up a hill). this is definitely faster than a human can comfortably walk for a long time. if that's sufficiently slow, I guess I don't have any objections.
Their "IT sector" is basically people who can work a computer and know how to speak English. Remove the last bit and there is nothing left.

And they would have no idea how to make anything "pay off" to the advantage of their citizens. India has been a nuclear power for close to 50 years now -- and yet you have more then half the population without basic sanitation every morning.
I wager Tim Cook would probably be far better for Tesla than he has been for Apple.
Again, that may or may not be an accurate characterisation of the circumstances.

The parent may genuinely be writing at the students request.

It’s seems reasonable there may be at least some students who genuinely want to do more work to improve their chances of being accepted in to their preferred choice at the next level.

> It only takes one error to kill your career

I think this overstates the case. Up to 40% of murders go unsolved in any given year. Most murders are committed by people the victims know, that's why they're "easy" to solve. If you don't know your victims, there's virtually no way for the police to link you to the crime unless you make a colossal mistake, like divulging our identity or your contact info to the person who hired you, as the police will be looking at them closely.

DNA and fingerprints, unless you're already a criminal where those are registered, would only establish you as serial murderer whose identity is unknown.
would it still be morally wrong if the police ran it? I think not they frequently run covert operations. Thus a non-police vigilante would not ve wrong either right?
Anything "audiophile" in the digital domain is all equally absurd. The only difference is that some require a half-second of consideration and others require literally no thought at all to identify as stupid.
Many artists use technology to create art. That doesn't mean they're not responsible for creating it, or that it's not art, or that others should remove the artist's name.
> You're pretending people are rational automata who make decisions in their own self interest, which is rarely true in life.

why do you think this? I would wager that most people are acting in the way they think is best, either for themselves or the people around them, either of which is a form of self-interest. Often in my experience what seems to me to be irrational from the outside is in fact very rational, and I just didn't have all the pertinent information.
I can suggest the recent Wolfenstein games.
Handbag producers don't claim their bags contain magic. The audiophile stuff producers do. The are making false claims.
I mean, these are related. If Tesla cars aren't safe for the people inside, people won't buy them. If they're not safe for others, lawsuits will follow. Bad for these are bad for shareholders too. But certain people will ignore this to their own detriment, and I expect Ellison to be one of them.

I had a teacher like that in high school. He taught AP/Honors government and had some of the highest pass rates for any teacher in the school. He stayed after school for a fixed time - 30 or 45 minutes - no longer - and most of that was spent with students. It took him FOREVER to grade tests and assignments. But, he was one of the best teachers I had in those 4 years and I, along with most of my peers, aced both exams that year (he did AP US gov in one semester and AP comparative gov in the other).
We've been doing that a long time!

> The super cheap units you find for like $10-20 will usually have serious shielding / noise issues

That's not true if even possible (because dac and amplifier are on a single cheap). I've tested like five different DACs, from $2 to $150, even those for $2 that play distorted sound and don't bother putting output capacitors for headphones have no noise/shielding problems.
Why is this kind of “confessional” necessary? This strikes me as very American - this need to think you’re “the greatest” at everything and then beat yourself up when you realise you can’t be.

Look... do we say Beethoven was a lousy composer because he never conceived the 12-tone system or mastered extended techniques or knew anything about Indonesian music? How absurd! Those were all things for later composers to discover and specialise in.

Specialisation is just fine, thank you. It’s perfectly fine to consider oneself a good programmer!, having mastered only one or two languages.

Americans, please quit the silly moaning and self flagellation and get on with your day jobs. Thanks.
In the area I taught, median pay was about $60k/yr. After 20 years and getting more advanced degrees, you could get to $80k/yr. Most of the teachers I worked with worked more hours per year than just about any software engineer I know. Only very lazy or very tenured teachers were getting the fabled summer vacation or winter break. I have more income, more vacation, and better hours as a developer than I ever did as a teacher
Not an expert but I think solar power would also be uneconomical if it wasn’t done at scale. The problem is that most recent new power plant constructions are unique designs, with ever changing regulations. I am sure nuclear energy would be economical if you were renewing a large number of plants at once (which will need to happen as a lot of plants are becoming really old).
What did anyone expect when everyone whole-heartedly supported more mandatory testing and measurement intiatives to help failing schools, almost about a decade back?
If you start emphasizing test scores, that's all that will be optimized.
Indeed they do. Some high end studios install balanced power. Which is more involved than just a power pole.
If you obtain a product legitimately you are allowed to sell it. This wasn't a counterfeit product nor was it claimed to be. Just because a company has a policy of only selling to authorized retailers does not allow them to restrain the trade of their merchandise by legal owners. It would have been a huge lawsuit.
In Afrikaans - spoken in ZA (south africa) - that is pretty much the actual word :)

I am a USAA member and think this is because the military is not losing pay or being furloughed. The DoD is fully funded in this partial shut down.

USAA and NFCU, while they do serve government employees, primarily cater to the DoD with these types of programs.
Yep. Currently a teacher myself, and I'm seriously considering quitting after this year. I enjoy teaching, but there's just so much BS crap that I have to deal with. Parents here (rural area in a Southern state) have no desire for education and often think their kids shouldn't have to do anything to pass. So I constantly get emails from Little Johnny's mother about his math grade when Little Johnny literally hasn't picked up anything except his phone all damn year. But I can't tell her that, or if I do it doesn't matter ("He'd do great if you taught him real world stuff"). The huge culture of anti-intellectualism leads to a lack of respect here, as does the whole "Those who can, do" type attitude. IT sucks.

Thankfully, my district doesn't require lessons plans except for the classes we're being observed in. They give us the syllabus and trust us to teach it. I love this, as it gives me the freedom to try and be creative and spend as little or as much time as I need on a topic, without being rigid in how I approach it. Sadly, a new hire last year came in and wants to change all that; we're now forced to give standardized tests across the same class (so all geometry teachers must give the same test), which implies we have to do it on the same day...So someone either ends up going too slow or too fast. It was damn annoying, and thankfully I'm leaving that department next semester (I'm certified for both math and science, so am moving to the latter).

And then there's education classes. They're all jokes, and the "research" is so BSed it's not even funny. And the writing quality of the Ed.D.s wouldn't fly for an undergrad at any top 20 school. It's hilarious, and they're all quite useless, and just talk about "theories" and never explain anything practical (laws, for instance, would be damn nice).
The encoder is my very favorite part of the robot. I've written a page about how it works in detail:
https://github.com/HaddingtonDynamics/Dexter/wiki/Encoders

In summary, it's a hybrid of digital and analog. To the standard quadrature encoder slit counter, we add sensing of the light levels as each slit covers or obscures the phototector. So we get e.g. 200 slits times 8096 light levels inside each slit equals over a million positions. It's so much data that we need an FPGA to process it fast enough. You can breath on the arm and it can sense it.

There is a constant battle between writing for sales/investment and writing for technical disclosure. Sometimes we get some chocolate in the peanut butter. It's certainly not phony, and I'm happy to answer any questions that anyone has about the real technical abilities.

The $2,999 price was for the Dexter 1 which was available at the time the article was written. The current generation is the Dexter HD which is more capable, much easier to build, and (as you noticed) more expensive.
GP (int al) only have to make one cock up to be publicly vilified. The organisations and institutions they campaign at for change can simply say "whoops" and not suffer too much.

That is not surprising in any way. It is very clear and defined that a question mark is a wildcard, and will be expanded. If you want a literal string, define it as such with a single quote.
sounds like a nice generic company value/principle
Oh, this reminds me of high school, when I asked a physicist my mother dating about the same idea. He worked for the Rand corporation and was overall pro-nuclear. Still, He considered for a second and did his best to explain...

What I remember of his explanation was the point that if you launch a payload of material into space, you have essentially placed that payload in an elliptical orbital path, one that intersects earth's elliptical path. And since orbits are periodic, that payload is going to be intersecting earth's orbit regularly, meaning that in this instance, the chance of the material coming right back into the atmosphere is quite high.
You know what's next - sell audiophile-grade RAM. Gold-plate everything.
If it's the parent writing at the student's request… I'd think it'd be more effective if the student themself emailed the teacher about the grade, wouldn't it?
Few years ago I visited a large apartment complex about 30 minutes south of Seoul in South Korea. The complex has Dozens of 30+ stories high apartment buildings. Assuming 30 stories high, 8 units per floor, and 25 buildings, we are talking about 6000 units. The unit I visited had 4 bedrooms. Despite such a high concentration of population, the complex itself felt like it was in the country side.

The key factor was underground parking (resident and visitor), with entrance to the underground parking connecting directly with the road. Within the complex are streets for cars with sidewalks like normal street, but strictly for emergency vehicles and moving trucks.

As I walked around the complex day and night, I couldn't believe the peace and calm I sensed as there were no cars moving around me. I kept looking around as I crossed the street as a reflex, but there were no cars to worry about.
> You can have open borders or you can have a welfare state. You can not have both.

That's not saying that it's okay to "defend a reduction of welfare payments to discourage immigrants from coming." It's saying that if you don't reduce your welfare payments, you will eventually be discouraging immigrants from coming, probably by closing your borders. It's pretty much a political necessity. So Friedman's argument is actually the opposite, "let's reduce welfare so we can afford to have more immigrants here!" Or perhaps "you can have your generous welfare but be careful, this will eventually lead to discouraging immigration to the point of having de-facto closed borders, with all the unwanted side-effects of that."
I think we can all agree that the best solution includes private and public trying to find answers to a problem.
Even if you use stockfish on a high end mobile phone, there is no human that can beat it. Standard or rapid. It doesn't matter.

There is absolutely no contest between humans and computers. Even Nakamura with an older version of rybka lost against stockfish.

This is like asking if a human can win a boxing match against a car.
I was in a grocery store when my cellphone, in unison with all the other phones in the store gave the clarion call for attention... I thought Russia had finally launched a 1st strike...
There's also the nuclear liability cap. Taxpayers cover disaster cleanup costs that exceed some fairly low level ($200 mil I think).

It's very expensive but also free insurance, basically.
Cheap Laser Printer – My Story
It seems like you mostly have a good understanding of how it works. A tracking fund would have to rebalance in the advent of a company issuing or buying back shares, when there is a corporate action like a spinoff or merger, or when a company is added or removed from the index.

Additionally, you have the reality that every day, investors buy and sell that fund. The tracking fund, therefore, has to liquidate or buy new holdings to match the NAV (net asset value) as shares are created or redeemed. This is where tracking funds will vary in their performance as some ETF providers might be a lot worse at matching up inflows and outflows.
Yeah, the pay is an issue. Sure, I make great money for a single young male living in an low COL area, but there's no room to scale. My mom retired from teaching in the same district I'm currently in with 31 years experience. She was only making 15k more than I started at. There's no chance to increase pay apart from going administration (and even then it's not a huge increase) or getting more degrees (and there's a limit to those).
This is also a result of bad plugin design.

Functions should be on fpath, zcompile'd, and loaded with autoload. Otherwise you have to read and parse 100s of lines of code every shell invocation... yikes.
Naive question: are these sorts of advertising/documentary things common in open source programming languages? Open source software more generally?

I watched the documentary and I found it to be compelling and well produced while also informative.
> That being said, I’m not following how attitudes in software engineering are related to the topic of this post.

Sorry, I probably made my point poorly. It wasn't about attitude in software engineering. It was how insanely overvalued the field is, with a completely out of wack investment to reward ratio. Few to no other fields come even close, and its siphoning people from all other fields as well as creating unreasonable expectations from them. That's obviously not the root cause, but it's something to ponder.

Essentially, all I was saying is that the article made me think about how crazy the contrast between those 2 professions is.
Ask HN: Any cool spiking neural network projects?
It looks like spiking NNs are the red-headed step-child of data science. Are there any spiffy projects going on involving these very energy efficient outsiders?
Actually, I'm not a racist scumbag so I'm at least better than that.
Presumably the backpresure of requests does not go away - when parents email for information, they do not stop just because they didn’t get a response. They will reach out through other methods. Do you know how that irreducible workload gets resolved, other than getting passed to colleagues who do put in extra effort/hours?
