One interesting concept used in some schools is that they will focus on only one topic for 2 or 3 weeks – and then another topic for the next weeks, and so on.

When you just focus on one topic for a few weeks you can go far more in depth, engage the students easier, do more complex group work instead of teachers telling them.

Even in normal school schedules it’s important than never (or close to never) the teacher actually teaches – the teacher can guide, but the students should work out how and why something works in groups. From math to history, from english to sports, this works far better, if students are able to discover and investigate on their own.

Whilst the DIN typeface was using a proportional font,
the FE-Schrift is a monospaced font (with different
spacing for letters and numbers) for improved machine
readability.

The German version of the Wikipedia article says more clearly that (despite the name: FE = hindering falsification) machine readability was the other important reason for the design and introduction of the typeface.
Yup, I am close friends/family with 4 teachers. One is pretty much done after this year. Another has been seriously considering leaving for the last couple. Both basically for the same reasons.

One summed up the problem as all the time and effort spent on standardized testing actually means that the system focuses almost exclusively on evaluating teachers (and whether they are following the prescribed teaching materials close enough) and could really care less about the individual students and the quality of the education.
Is it efficient to wait 6 weeks for results rather than half a week because you preferred Python over C++ during the half-day (half-week) respectively of coding?

Is it efficient to use thousands of kWh in electricity rather than just hundreds?

As always, the answer obviously depends on your problem.
In the UK, I've seen richer parents simply send their children who didn't not meet private school's admissions and performance requirements to state school (the one I attended!) whilst their siblings passed the requirements and remained at the private school.

I remember two kids from primary school seemed to have disappeared and then reappeared a few months down the line from school year start. They didn't make the cut like their siblings. I think one of those kids, thinking back, was the son of the managing director of the company that is now TalkTalk pre-acquisition.

True

It's amazing how somethings are extremely inefficient, and even worse, nobody questions themselves why this is like this

Most of 'this is taking too long' is because of IO, still, sometimes it's done in a very inefficient way as well

They're all specialized DBs. There is no general case.
Private schools don't necessarily spend any more per student on teaching than public schools do. Mine spent less, though I got more out of it.

One of the differentiators, I think, is that only parents who actually care about education spend >$10k/year on something they could get for free. Most of the children attending have significant support from their parents and come from stable homes.
>Many of them will have some idea about theoretical time complexity, but then see nothing wrong with what should be a very trivial operation taking several seconds of CPU time on a modern computer.

In my experience developers who over-optimize, or who optimize with disgusting hacks, are a vastly bigger problem than developers who don't optimize at all.

There are a vast number of problems where a several second wait for the user is almost irrelevant compared to the damage done to the code base by optimizing those few seconds away.
For something as LibreOffice I think it absolutely makes sense. The most frustrating thing when working with such software is a crash when you haven't saved your work. Auto-save may help, but it's still annoying.

What this gives you is a reliable way to reproduce obscure input scenarios that trigger a crash, which is often the only thing that's missing for fixing long-tail crashes. Of course, if there were now hundreds of such crashes you'd need to start triaging to avoid devoting hours of bug fixing to crashes no one has ever seen or will ever see, but if it's just a dozen rare ones and one high-profile frequent one ... I wouldn't think about triaging yet.
> The internet is not the main culprit for the decline of both the brothel and prostitution; it's only helping to accelerate it.

VR is going to be how that happens. I tried out VR pornography and there is very little a strip club offers over it: food, company and drinks. It's what made me realize what the true potential of the platform is.

It would be possible to implement a brothel with VR and teledildonics which, while not 100% real, would neatly skirt all the issues with real brothels: the law, pregnancies, customers who fall in love, the STDs and the moral leap required to walk into one. I'd do it myself if I hadn't figured out something far simpler to get off the ground.

When I worked for a loan processor, they were quite happy running over $100k/hr revenue through a single instance of PostgreSQL. There were slaves to offload analytic and report loads but all transactions went through a "SPOF" and we just manned up to keep that database running. Don't tell me "real apps" are all that redundant and bullet-proof. Designing and operating redundant infrastructure is much harder and costlier than most make it out to be.

I hope that the fix to the QoS language gets through, since it has large consequences for fair competition. A few years ago a top 3 ISP in Sweden used QoS software that incorrectly identified League of Legends as P2P, making the game practically unplayable for almost half a year. The resulting effect was that a 40ms connection turned into a 3-10s delayed one, costing Riot revenue and unnecessary costs in support and developer time. The only thing Riot should be happy about is that this happened during that time when the MOBA market was limited with few competing titles (It was before DotA 2), as this ISP would have a created an distorted market within their customer base.

This ISP was of course not the only customer of the QoS software, but I am rather sure it was the single biggest one.
Agree 100%.

Years ago, I got a copy, and read it from cover to cover. After however many pages of bacteria and protoctista, dozens of phyla of weird, unimaginable, almost alien single-celled organisms, I eventually got to the animals. The first phylum is the placozoa, these little guys:

Not one-tenth of the problem as people who wrap trivial computations in "enterprise" crapware and use 100x the CPU they really need just to relay a few bytes of data from system A to system B. If you have ever used Java and XML I am looking at you.

Doubtful that operators of the Panama Canal would be holding up traffic because of the proposed Nicaragua canal. After all construction on that project hasn't even started yet. Furthermore, the new, bigger Panama 3rd set of locks are now being tested, due to open next year.

Doesn't make sense for Panama to slow things down in view of the loss of income, the fees collected are serious money, probably the major income source for the country.

Next year would be a very interesting time to visit the canal re: opening of the new channel. A few years back I was on a cruise that traversed the canal, a highly educational and memorable trip worth doing. The Panamanians we encountered were proud of the Canal expansion project, a significant national achievement, something important to celebrate.

No, but you did, and your deep assimilation of the insights therein has enabled you to substantively answer challenges such as the one I posed.

And it doesn't matter, but yes, I volunteered weekly for six years in a fourth grade classroom. I still wouldn't tolerate the response you just gave for anyone claiming to be an expert on some topic, including myself.

"Expertise" has to mean something other than "criticizing others for not having read the same books." It should mean a self-consistent, accurate, predictive worldmodel that can deftly show the errors of an invalid one without attacking the presenter.

I wouldn't call it theoretically the best. It is affected by outliers and doesn't make any generalization at training time. This latter point raises the questions whether it deserves the name learning. I would say linear models are typically a better learning algorithm; I wouldn't know what to call "the best" algorithm, but it might be deep learning nowadays.

>Not one-tenth of the problem as people who wrap trivial computations in "enterprise" crapware and use 100x the CPU they really need

I still doubt that the CPU/power/cooling cost of having systems infested with hacky enterprise garbage is its biggest drawback.

That crap also causes expensive bugs and huge maintenance costs (e.g. relatively simple programs that require a team of 12 programmers a month to implement the simplest feature).
Very interesting, if unsurprising that increasing demand on attention reduces efficiency. I suppose that's what I dislike about the busy visual displays installed in new cars, and why I turn it off in rental cars. Hard enough to drive in an unfamiliar car in an unfamiliar city without the additional distraction.

I'll read the article in detail, but seems logical that other sensory input would have similar attention-splitting results. I was thinking about the apparently preoccupied drivers using their mobile phones and trying to negotiate downtown traffic at the same time.

Lessons may be in it re: design/engineering of instrumentation for automobile operation and other critical attention tasks. Basically, would seem fall under the heading of constructing UI that minimizes risks to attention.

Here are some of the arguments I've seen:

-- testing itself takes a lot of time away from instruction, sometimes days at a time for each of multiple tests.

-- In addition to learning the material that's officially tested by an exam, students are forced to study the idiosyncracies of the exam: how questions are phrased, how graders expect to see written answers, etc. That takes more time away from studying actual curricular material and forces students to focus on something they, their parents and their teachers all find silly and boring, reducing respect for the education system.

-- The material that's on the test is often the lowest common denominator for what students should know, calculated over a US state or group of states. This means there will be material that's not on the test but that everyone thinks in a particular community thinks kids should learn (history, art, music, etc.) or even that most people in a state think should be taught but a vocal minority oppose (comparative religion, black history, evolution, etc.). That material will be left off the test, and a teacher won't have time to cover it because he or she has to spend all the class's time on stuff on the test. If a science test will never mention Neil Armstrong or Neil deGrasse Tyson, a teacher has no incentive to mention either of them, and may even be penalize for doing so at the expense of more practice with the density formula.

-- Teachers are evaluated based on test scores, often to the exclusion of other factors. This stresses teachers out at test time, which causes them to stress students out. Students come to dislike school and learn less.

-- The tests are sometimes flawed, but by the time people realize the results are wrong, their results have already factored into policy, personnel decisions and student placement.
I was fortunate to have spent a year or so in Pakistan helping launch Easypaisa - one of the biggest mobile banking deployments globally at the time.

I was told I was lucky to survive my first day without getting shot - I hung out on Karachi beach with the locals on National day which apparently made me a huge target for theft or kidnapping.

While I was in Islamabad the Taliban took over the military headquarters, the city was bombed a few times, and I spent one day in Karachi moving between safe houses as rival gangs took to shooting each other in the streets.

My wife is half Indian - we had to hide her identity when she visited (we went with "Persian").

The country was one of amazing contrasts. Kindness and terror, beauty (natural) and ugliness (man made).

I say "fortunate" because of the (a) new perspectives gained while being there; (b) having the pleasure of working with some of the brightest and hard-working people I have ever worked with; (c) being part of a project that has helped empower tens of millions of people.

The most beautiful place I ever went in over 40 countries I have visited was the foothills of K2 mountains, and watching a Polo match at the birth place of Polo in Baltistan (despite my Indian wife and I being surrounded by 15000 men chanting "Death to India" while war raged on in the SWAT valley a few hundred km's away).

A last footnote. Pakistan has been in the middle of so many proxy wars and have such a crazy history that most people I met have woven together the fabric of truth and fantasy to create some of the most amazing conspiracy theories you could ever imagine.

It would be great if they were automatically requeued (maybe at the end of the list?) and were able to be resumed without starting from scratch (I assume behind the scenes uploads are multipart?).

>The grandparent post isn't talking about over-optimizing.

Nonetheless, warning bells go off inside my head whenever I hear that opinion expressed without the caveat "if it isn't a problem for the user, leave it the fuck alone".

>You shouldn't have to add disgusting hacks to complete a trivial operation in less than a second.

If a trivial operation takes more than a second that's almost always indicative of a bigger underlying problem of crappy code.

Cleaning up dirty code that incidentally causes performance improvements is fine, but changing code specifically to make performance improvements without improving its overall quality leads to a downward spiral of shit.

I do not think that it is that useful. While i have seen people greatly overestimate computing complexity of simple tasks like comparing numbers, i do not believe knowing how long such instructions take gives you much more. Especially interpreted JIT compiled code is not exactly predictable in performance and optimizing single instructions not very useful. However it is a fun game and does indeed give a better rough assessment for performance in various implementations. But if you really like to optimize your code these are just some hints. You will have to run benchmarks for every use case.
One of the risks here is that it's very hard to ascertain the support situation around some of these third party products.

If you design your application to communicate to your database through a certain sharding solution, and the you find that sharding product becomes abandoned, you can be in a very difficult position.

That wiki lists at least one product as "stalled".

If I run into a Postgresql bug, am I going to get told "we have no way of debugging that with your third party clustering extension in place"?

These are all obstacles that can be overcome, but just jumping on a random clustering project should be done with caution.

As a related part of clustering, I'd love to be able to do downtime free version upgrades like in Oracle - it would remove one of the major reasons for clustering.
