Imagine blending the traditional educational structures into EdTech and using network engineering to clamp down what can be accessed in a classroom device to only the educational software modules needed. For example, you could put timers on how long each module is open. Give teachers the ability to override them and tap into each student individually if needed.

The issue is that the surrounding infrastructures would need to be much more competent than they currently are in education. I worked at an educational institution in the IT department, and the level of knowledge the IT staff had was abysmal. It was surprising that anything worked at all.

Additionally, not everything needs to be gamified. Somehow this notion that everything a child interacts with on a computer has to mimic a video game is a really narrow way of thinking. Instead, we could start with basic computer usage skills such as file management, and system configuration, and using core tools such as word processes and image manipulation software.

Instead of dumping kids into the world of Google which is a for-profit mechanism that is inherently designed to get people to click on stuff as much as possible, we actually as software developers need to re-think EdTech and have it be learning first.

T&C are dark, twisty forests of legalese that can shift, seemingly at any time. As a consumer, if you want to do something as simple as pay to park your car, you need to sign the T&C in blood or you get towed. Is it really an agreement if you must agree to it for basic necessities?
Over 30-ish years of work, I’ve lost about 0 coworkers without warning or transition to lotteries or similar events, and more than a few (whether permanently or for an extended period) to unexpected sudden death, injury (traffic related being particularly common), or other unheralded misfortune (law enforcement involvement, on a short out of country trip and then encountered visa issues, whatever.)

“Bus factor” is a more realistic reflection of the threat model, and resonates with experiences anyone who has been working more than a short time probably has more than “lottery factor”.
Nope! We're still heavily investing in scaling Protobuf. In fact, our data quality guarantees built into Bufstream are powered by Protobuf! This is simply an extension of what we do...Connect RPC, Buf CLI, etc.

Great tool, guys
This is a silly thing to say. There's no evidence that edtech was forced to band students to grade levels due to equity. It's just as likely it happened due to Bush's Leave No Child Behind, or out of a desire for administrators to follow rules.

Never underestimate how upset people can get when a kid does longhand addition the old way (write numbers under each other, carry the ones) rather than some more "holistic" way.

If you really want to have a solid overview understanding of World War 2, and you are just not the type to read two long books no matter how good they are, then here is probably your best option by far:

1. Pay for an Audible account. (Or figure out how to get free access to audio books from your local library.)

2. Listen to the books “Winds of War” and then “War and Remembrance” by Herman Wouk.

The drama and characterizations are just fine, and will pull you right in to caring for Pug Henry and wanting to know what happens to him and his family.

The battle scenes are true history and will blow you away, and teach you a lot. Midway, incredible.

The coverage of the Holocaust will break your heart, but make you think, “wow, everybody in the world should read this once”.

The character evolution of Werner Beck, in light of today’s world events, might terrify you. Whole nations don’t all of the sudden become evil. Evil powerful leaders push evil down into a country over time.
I worked in EdTech research, it's a shitshow. Indeed the focus is on institutional learning while the power of tech is to empower people outside formal education. The amount of wishful thinking is unbelievable, protocols are often very weak, hard problem aren't addressed and focus is on what is easy to measure. There is so much potential, but it's vastly underexploited.
I guess the tactic is to pass it before the new Trump administration is in power.
I always just operate under the assumption that anything digital may one day be public record, it’s actually way easier to think about.

Like that Ben Franklin(?) quote: “three people can keep a secret if two of them are dead”, if you want something to be a secret just don’t put it on a computer at all, simple and effective.
Imagine if you could actually download it too. Why is it taking so long?
Isn't an edu version of YouTube basically Nebula or those other platforms I see big YouTubers talk about?

I honestly think people should stop trying to make sanitized versions of YouTube though. It doesn't really work (YouTube Kids is still a disaster and often inappropriate IMO), but all the extra rules and regulations severely inconvenience the creators and viewers who are happy with it as an entertainment platform.
> biotagging

Sorry, what does this mean? I couldn’t find anything on Google about it.
I don’t think I’ve ever worked with a project manager who wasn’t a total pseudo jobber. That is to say, I have worked with some wonderful project managers, but they got things done rather than “manage projects”. They’d be hands deep in Active Directory, weird json stuff to help find issues with OCR or working on change management and training when a new system needed to be adopted. But the whole “agile” side of project managers, scrum masters, IT business partners and so one have always just gotten on the way.

Usually what happens is that they become middlemen that can’t actually relay information between developers and the businesses. As a result developers and digitally inclined business people tend to talk to each other directly while they let the pseudo jobbers waste everyone’s time because… because it’s “best practice”.

Hah. Especially rich when you consider that the whole “agile manifesto” was thought up and sold by people who haven’t worked in software engineering since 20 years before Python even existed. Of course it doesn’t work. Not because any part of it is particularly bad, but because every part of it is extremely vague and completely unfit for reality. If you follow any sort of practice which isn’t YAGNI religiously you’re going to fuck up.

Projects ship because one of the people who do actual work gets fed up with all the bullshit and simply does what needs to be done. All the “project managers” and other role players are only there because SWE management is full of people who can’t code anymore. You don’t see all these pseudo jobbers in IT operations, and you don’t because SysAdmins want to be SysAdmins.
> Or, almost as bad...

IIR, that problem-solving method is called "Fermi estimation" - after the Nobel-prize-winning physicist who was particularly skilled at doing it. Perhaps you're smarter than you give yourself credit for?
So the thing is, if the lobbyists succeed, there will be much less deportation than promised (which, practically, ought to be OK).

We do have TASS formally claiming that they won Trump his election, just the other day, and stating that he owes Russia and will make good on his obligations. I didn't see THAT coming, but it appears to be the real website.

If the lobbyists fail and Trump does manage to deport all the workers and jail his enemies in spite of it hurting business, it might be an indication that the success of America isn't really the goal. Just saying, if Russia's not lying about owning Trump, he might be more useful to them as a wrecking ball, in a position to ruin the country and break the dollar as the world's reserve currency. This would be disastrous, but maybe Russia would like to see us experience a disaster.

Some people will find that a useful motivator to endorse crypto.

Could I politely suggest writing out the full acronym the first time, and then using WGU subsequently? It'd be a good deal more considerate of non-U.S. readers.
Series and parallel: How not to add capacity to a lithium battery pack
From 2018 - 2023 I built custom electric cars. Now I am recording a series of videos for you where I explain the concepts I taught myself for you to learn faster than me.

People get confused by series & parallel battery configurations (including me when I started out), so this is my 7th video on basic EV concepts. Questions like the following I had, and others ask me now:

- How can I merge two battery packs?

- I want to add capacity, why can't I just put it in parallel when I need the extra capacity like a range extender

- ...

It seems intuitive but isn't always.

I also made a little widget where you can move the sliders and see sample battery packs.

I hope this is worthwhile and easily digestible. I animate as much as I can to make the concepts clear to understand.

Let me know if this helps.
Does this mean the Trump administration is for or against software patents?
Now now, exabrial was simply arguing for small government. And what government could be smaller than the arbitrary whims of a single man!

Not quite what you are looking but if you're interested in Operation Market Garden: for the Dutch maps there is https://www.topotijdreis.nl, which gives you historical maps with a year slider. This can at least help one visualize how cities, villages, and topography at through the years.
Interesting. My understanding is that the US refused to deliver after Turkey bought S-400 systems from Russia, and will still sell the F-35 to Turkey if they stop. Do the systems share radar returns with mother Russia or what exactly is the concern?

I recently wanted to reverse engineer some Websocket packets for a game I was playing.
I used BurpSuite as a proxy to bypass the SSL encryption. It also has a pretty handy tool that will monitor all websocket traffic.

After that I used ImHex, pretty much exactly like in that blog to reverse engineer the websocket packets. The DSL is a little finicky but once you wrap your head around it, it`s very nice and powerful.
Pandora is also way more trainable. You can train that recommender with your thumbs up/down, and it's been like that for 15 years.
Yes it leaves me guessing.

You can show up later than him. Disrespect his time the same way he disrespects yours. That would be "fair".

Or, try not to work with him anymore.
Of course it is, but it's not an either-or expense it's both-and. For most projects you need to do a lot of trial and error to get the right image, so it's the cost of someone who knows how to do that trial and error effectively + probably a few hundred generations per hour.
I got nerd-sniped on this, because I actually hadn't heard that before and would be horrified if it were true. It took some non-trivial digging to even get down into the "well, what does foo->>'bar' even map to in C?" level. I for sure am not claiming certainty, but based merely on "getIthJsonbValueFromContainer"

Yes, von Neumann was tasked with doing a write up of what Eckert and Mauchly were up to in the course of their contract building the eniac/edvac. meant to be an internal memo. goldstein leaked the memo and the ideas inside were attributed to the author, von Neumann. this prevented any of the work being patented btw, since the memo served as prior art.

The events are covered in great detail in Jean Jennings Bartik's autobiography "Pioneer Programmer", according to her von Neumann really wasn't that instrumental to this particular project, nor did he mean to take credit for things -- it was others that were big fans of his that hyped up his accomplishments.

I attended a lecture by Mauchly's son, Bill, "History of the ENIAC", he explains how eniac was a dataflow computer that, when it was just switches and patch cables, could do operations in parallel. There's a DH Lehmer quote, "This was a highly parallel machine, before von Neumann spoiled it." https://youtu.be/EcWsNdyl264
That's exactly why they're doing it now.
> but the metro is at least an order of magnitude (if not more) more expensive to operate

Many metros, specially the automates ones are really cheap to operate. If you compare capacity and cost then metro lines are far more efficient.

A lot of old tram lines are simply done by buses. Often even electric buses.

I'm all for more trams, but they are just one part of a much larger transportation system. Using them as the primary center to outskirts mechanism isn't a good idea.
"There are too many profitable incentives... Power generally resides with those who benefit... The system is setup to fail because that's what's profitable in the long run for those seeking such profits. And because they can lobby, and use their wealth to influence politics, it won't change. Something else needs to happen first."

Who exactly are you talking about?
Yep, we found the google-youtube url issue too.

Right now, I have youtube filtered by MAC on my Roku. I would like to add granularity so that they can watch some youtube, but they make that too hard. So we all just share the living room TV right now so that I can just keep an eye on things.

I'm still getting outsmarted though. I have locked-down parental controls on Minecraft so that my two kids can play together but not invite or be invited to stranger's worlds. But somehow, I see other people in there. Microsoft parental controls leave a lot to be desired. I don't know how non-tech-oriented parents do it.
This linter tool checks a schema for those issues: https://www.npmjs.com/package/schemalint (it is linked from the doc itself, too). It is kind of handy.
This needs working schema migration process, including ability to undo schema change if the new column tanks the performance or breaks stuff.

If there are CLI tools involved, you also need to ensure you can handle some downtime, or do synchronized version update across company, or support both old and new schemas for a while.

If a database is not part of team's primary product all of this could be missing.
Nice Idea man
On top of that the teacher has to juggle two tracks, the normal one and a special needs one. There has been a push for awhile to put mentally disabled kids in with their age peers and the teacher has to handle it, maybe with a low pay assistant.
I took about 60 credits - ~8 hours per week each school semester - of Computer Science courses back in the mid 00's at a top state school. Besides the 101 Course, heavy on Java syntax; and Software Architecture where one learns the dark art of Swing, we used pencil, paper, and white boards (even a few chalk boards!) for the rest.

I use concepts like Dijkstra's algorithm and the Turing machine regularly in my job. They are very real to me - more real than any programming language - because I sat for hours taking paper notes off a whiteboard while some OG Computer guru discussed the topic.

If I didn't need tech to learn Computer Science, kids definitely don't need it to learn Algebra.
> I want to believe this but I can't honestly imagine someone actively thinking about this and dedicating part of their work to misinforming the poor intentionally.

Populism is exactly this - misinforming poorly educated people with bad scary words, "others", "easy" fixes.

> Inflation is bad! Crime is bad! We'll just deport 20 million "others" and everything will be allright!

Or:

> Let's send all the money we're spending on the EU on the NHS, 350 million pounds per week more for the National Health Service!

In some countries, like the US, there are active efforts to sabotage education, or at least cripple it - by reducing funding to a point where educators have to spend their own money for supplies, get burned out, have poverty-level wages, etc. Those can't be accidental.
True, but as people here know, Cell Phones are now nothing by Spy Devices. Any cell company can get your data and pass it on to anyone they chose or who pays enough.
Bing and Google do have the benefit of websites defining their market via their webmaster tools sections. And a critical mass of click through metrics, etc.
yeah, it's there, but I tend to think that "equity" is what people end up reaching for as a rationalization of the emotional need for uniformity / conformity / familiarity

It sort of "fits" but it just doesn't explain very much on its own
The best school which I ever attended rigorously divided academic and social classes --- academic classes (reading/English/math/science) were attended at one's ability level, while social classes (homeroom, phys. ed., social studies) were attended at one's grade level.

There was a 4 year cap up through the 8th grade (so I was a 4th grader attending 8th grade English, math and science classes), and after that, the cap was lifted and students could begin taking college courses in 8th grade --- some of the teachers were accredited as faculty at a nearby college, and if need be, arrangements were made for students to travel to the college, or professors from there to travel to the school.

It was not uncommon for students to graduate from high school and simultaneously be awarded a 4 year college degree.

Apparently, the Mississippi State Supreme Court declared the system illegal because it conferred an unseemly advantage on the students who were able to take advantage of it, with no equivalent compensation for students who were not.
Ok, the before-before times then.
Confused, why would Republicans be against this?

One interesting thing about these newfangled matrix/AI/ML accelerators that’s very rarely mentioned on the internets, they only deliver that many TFLOP because they operate in very low precision.

nVidia tensor cores support int8, couple versions of FP16 (BF16 and the standard IEEE one) and FP19 which they call TensorFloat-32. I think Intel AMX only supports int8 and BF16.

None of them supports FP32 let alone FP64 input numbers, which makes them completely useless for traditional GEMM stuff.
"Holding kids back" is not the reason EdTech fails at scale.

The problem is that people who succeed in tech are able to effectively educate themselves, alone, without a dedicated human teacher supervising them or a group of student peers. (You need this skill to succeed in tech, learning new APIs/languages from written materials and online videos.)

The techies who build/fund EdTech wrongly assume that everyone could do this if only they had access to the learning materials, or if the tech vaguely simulated a teacher (an interactive textbook).

But for most students, fitting in with peers and earning the respect of their teacher is the only reason they're bothering to learn at all.

(For kids especially, adult career prospects feel so remote that it scarcely seems worth the trouble, whereas earning respect right now is a very, very concrete problem!)

Banding kids into grades is the only thing making most kids succeed. I guess that is a "crying shame," but it's a tragedy, not a policy failure.
The gaps are on the standard library side: clang libc++ has fallen behind a bit on conformance, but you can use libstdc++ on clang as well (and it is the default for example on Linux). MSVC lags on C conformance, which is known not to be primary concern for MS (but still miles better than what it used to be).

In any cases these tables only help up to a point, even green cells often hide bugs and conformance divergences.

Still for most straightforward code compliance across compilers is very good and significantly better than the dark ages of two decades ago.
+1, very powerful stuff.

My anecdote: I was expelled from a vocational school my senior year, thanks to EdTech I returned and finished the year within a month
Yes, I totally agree. The T&C situation is dire and need to be addressed. For instance, the idea that you engaged in anything remotely like "consent" because of vague generalities in T&C documents is laughable on its face.

That said, it's the legal framework we have to deal with in the now.
It is my understanding that the reason why this is is high performance situations. You have some other system that can figure out if something fail, but with this feature you can move the high water mark so that you don't have to redo as much. But if you got the timing right and there is a failure you can go ahead and assume that when you restart again you'll be getting some stuff that you already processed. The problem is when you don't have this for mailing before the auto commit. It is meant to be done far after processing in my reading of it, but it does certainly seem like there's a contradiction that it should auto commit but only stuff so many milliseconds before the auto commit time?
"Bergeron" is one of those rare things that's just presciently ahead of it's time it's almost spooky (kind of like "1984").
