The “most” I was referring to wasn’t the most of all parents, but of people who you say should just go out and start a new school system. It seems somewhat self evident that the people who are homeschooling their kids have some % that do so because they see the school system as a failure. The point is if you’ve flipped the bozo bit on public schools, the next fix is go to a private one, and the next is to homeschool, and only after you’ve decided you care more about education itself and not just your own children would you actually try to attack the problem in the way you state.

You’re really digging in here, and seem to be taking personally something which seems plainly obvious to many successful people: school failed to prepare them for their professional lives, and in many cases school was a physiologically damaging, stifling experience. You keep trying to turn this into a relativistic argument, or think I am saying schools are an abject failure based upon data. This isn’t an argument based upon data, it’s an argument based upon a constellation of anecdotal data. The reason you see a lot of software engineers talking about this is because they see this as a problem, and many see it as a problem not because of data, but because they feel based on their own experiences of them and their children that something is very wrong with the way we educate the young.

Edit: also, you keep implying that I said fixing these problems would be easy. Where did I say that? My original post was literally a few words - I am generally disgusted when elitism enters threads on “hacker” news. Credentialism is stupid, and good ideas can come from anywhere, and often do come from people who have a deep talent stack beyond a narrow domain. Chastising people for having opinions on subjects they are under informed about is dumb - at worst, that’s an opportunity to (ironically) educate them. At best, their beginners mind may offer a chance to think differently.

I’d be much more interested to read about how cellphone location tracking is used to geotarget campaign ads to unwilling recipients who have not opted in to receive messages from the campaign, or have their location data shared.

Just an aside, I have met Kim a few times at various conferences. She is an interesting person, in a good way. She came to the book as an infosec neophyte. We talked about her process as something of a technologist outsider and how she decided what to focus on. Ultimately, she decided the storytelling was far more important than the technical details, though she felt those were incredibly important as well.

Excellent explanation! Couldn't have said it better myself.
> If people in year 2100 would then start and go and destroy historical objects from the second world war I would suspect people to get a bit annoyed.

I would hope that that the people in living in 2100 would still recognize the Nazis as Bad People. People recognized in 1970, and still recognize, that the Nazis were bad.

The fact that 1890-1930 people thought the Confederates who fought to support slavery were fighting for a worthy cause is that is strange IMHO.
52 characters vs 64 characters for a 32-byte public key is a decent improvement if you ask me. Or, more to the point, aiming for anything denser makes the alphabet less friendly.
Because for a while they put a maximum on it instead.

At the time, netbooks were growing organically and could be had with 2 or 4 gigabytes un some cases, with Linux for less that the Windows version.

Microsoft countered this with cheaper versions of Windows that were limited to lower specs, such as 2 gb.

This was the so-called "starter edition" of XP and similar licensing programs for Vista.

The policies might have changed with Windows 10 (not sure), but the legacy remains.
Is it possible to achieve any speedup using domain specific hardware accelerators for solving stiff (but linear) differential equations with large number of states ?
It seems the author is not thinking about games (educational or not) in the common sense, but in way broader terms:

> A video game is just:
>
> (a) a simulation of reality
> (b) with fast feedback loops.

I’d agree with both of you.

“Educational” games are a hard sell. I’m a parent and the educational mini-games pushed by school is boring to death and won’t stick with my kid. It’s hard to articulate, but the underlying principle of trying to teach a specific thing doesn’t go well. Yet the ones that I found that seemed to work ok had way lower “educational” focus, and it was hard to recommend over any other standard game.

Then simulations stick very well.

Minecraft is a barebone one and “teaches” a ton of true and untrue stuff. Racing simulations stuck, flight simulator stuck, hell even lego simulator stuck. I see animal crossing in the same vein, and am trying to find a serious fishing simulator as a beginner’s guide to fishing. And kids can spend hours on Streetview for the same reason.
If it's important for me to memorize, the only way that works for me is writing down what needs memorizing, like with a pen and paper.
When Islamic State was up and coming, the news reported that its capital was Al-Raqqa. I didn't bat an eye. I did bat an eye at my own non-eye batting. EU4 and the (save scumming) glorious return of the Byzantine Empire had forever seared into my brain where the place is.
Besides monarchs in the past, for the first time in the history of Planet Earth we have many people and corporations that have more money than governments and so with that comes the responsibility of "acting accordingly". I believe that in a good light this will continue to assist humanity in ways never thought of before as human ingenuity is always more nimble than large bureaucratic organizations.
I run my G603 on a single AAA battery with an AAA to AA adapter. So far I've been exclusively using "dead" batteries from other devices – each lasts a couple weeks! (In low Hz mode at least.. I don't feel any benefit from 1000Hz mode, even in Counter-Strike.)
Preliminary Theory of the In-Group Contrarian
I'm also curious about this, and what "real world" Prolog actually look like.

On one hand, I think the paradigm really simplifies some things, but then on the other hand, everything else (aka routine programming tasks) seems much more convoluted and awkward.

I think PAIP may have been on to something, embedding Prolog in Lisp, but that's less elegant and more difficult in most other languages.
>can be dealt with later

mob style?
None said to replace human interaction completely. On the contrary, the examples given by the author includes plenty of human interaction, with fellow players and teachers alike.

The point of the article is to give games and software more "room" opposed to what's right now in education, meaning only boring teachers that will simply go through their lessons without a sliver of passion.
Norwood retired when Gordievsky was still in Denmark if I have my dates correct, which is probably why he never heard about her (he never made it quite to the top of the tree).

"I did what I did, not to make money, but to help prevent the defeat of a new system which had, at great cost, given ordinary people food and fares which they could afford, a good education and a health service" (As with most Soviet spies she lived the lie until she died)
There are tools to transpile typescript only, without doing typechecking, which dramatically reduces "compile time." It's very useful for a quick development iteration cycle, and then do a full type checking pass before merging and during CI.

Public, none of them are private. It wasn’t me tearing them apart but more of pointing the actual flaws and negatives in weight of the actual good stuff.
Yes, targeted advertisement is already massively abused.

Furthermore we already know different "better" advertisement models.
There's also the reality that USB isn't really that much less of a mess than Bluetooth. With Bluetooth you have interoperability problems between the controller and the target device. With USB, you have that + the interoperability of the cable.. and it's a mess. USB does overall work better than Bluetooth, but the problems he's highlighting in the article very much exist in the wired space (including the device polling screwing up latency).
How to Fix Bad Credit – (4 Steps to Follow)
This comes down to your metrics. If you're suggesting that quality of life here is lower because of computers I would argue that it's tech companies that chose to establish themselves here, which increased the number of highly paid people wanting to live here, which drove up housing prices, traffic, and income disparity. The computers themselves are not the cause. It would be the case with any industry where there is one major physical center, such as Milan and art/fashion. As we've learned with the COVID-19 pandemic, work from home could allow tech companies to headquarter themselves elsewhere, or employees could live where they want.

As it is, I wouldn't mind seeing some level of tech exodus since I live in the area of one of the shittier Bay Area commutes. But computers tell me when traffic is especially bad and gives me alternate routes.
All large organizations are the same. There are hidden experts who keep the machine running, and there are outward showmen who generate a lot of heat and light. Pareto suggests the hidden workers are 20% of the total, and I believe it. Not only are they in the minority, the people who know what they're doing often are passed over for promotion because the system would fall apart if they moved from their role.
I would choose C++ because the tooling is superb, talent is widely available, it is performant, there are libraries for pretty much everything, and it's a great language.

Oh and by the way, LLVM is 100% c++.

Saying it is too dangerous and complicated is absurd. It is easy to write safe code in C++, having been doing it for almost 30 years.

You are throwing around lots of assertions - challenge you to back them up with real data.
Zachtronics (and probably Factorio too, I've never played it) games always feel like programming in disguise. I'd be interested in seeing if there are educational games that can gamify more than just programming/automation. (I suppose KSP gamifies orbital mechanics)
Bluetooth is way worse than good custom protocol dongles (e.g. Logitech "unifying receiver")
https://en.wikipedia.org/wiki/Harold_Wilson_conspiracy_theor...

It's a very murky, embarrassing, and oleaginously classified hole to go down. When you factor in the alleged practice coup at Heathrow it gets very very murky.

Michael Foot was almost definitely an extremely naive soviet cooperator - but not a spy, which is what was alleged (He successfully sued on that particular allegation but a civil case is almost literally meaningless when you take into account that SIS have no declassification policy other than no and MI5 wait decades)
The reality is that if you poke yourself out of the Mac & laptop world, there's plenty of desktop computers without integrated Bluetooth support, and Bluetooth <-> USB adapters are pretty cheap, so vendors usually ship with one bundled to ensure they don't have to deal with tech support issues from people thinking they have Bluetooth support in their computer when they don't.
I'd like to see some numbers on this. I'm sure there are some chips where it's the case but are we talking small ARM cores or larger desktop and server chips?
I've spent a lot of time thinking about this. I had a fairly blasé education that involved switching schools a lot. Looking back, I can see that most of the information recall I have came from video games. The Civilization series taught me history, math science and logic came from the Dr. Brain series and a hodgepodge of other games, time and resource management came from Sim City and real-time strategy games, and more formal and specific subjects from Khan Academy.

The problem here is one of reward. I loved the challenge inherent with Dr. Brain; the puzzles did a great job at teaching basics of chemistry, biology, math, and I was actually accomplishing goals I was interested in. I think that the disconnect it that the people making these purchasing decisions do not remember what motivates children, what goals they are interested in achieving.

Static types are documentation. Better yet they're documentation that can't go stale without a computer yelling at you that it's wrong.
Andrew Carnegie definitely had "more money than governments". Same with other titans of that time.

He was a really shit person when in came to labor -- hiring literal private armies to straight up lay siege to his workers -- but he did basically create the "rich guy gives away his money as a social obligation" model of... maintaining... democratic... government? Or, to be less coy, model of staving off communist/socialist/fascist revolution. I truly and sincerely hope today's ultra billionaires are as smart and realistic as Carnegie in this respect.

Carnegie emphasized education in his giving. Limited success. His library movement was largely successful, but his trade school turned into yet another hyper expensive prestinge-driven private university. Although I guess it was the brith-place of a lot of the computer technologies that made the current crop of ultra billionaires rich.

I think we're over-due for someone to emphasize healthcare in their giving. (Gates did this, but not in the USA.) We're also over due for a labor backlash against this sort of obscene wealth concentration (and not even as a value-laden statement... just as a "lessons from history" thing, the pendulum will probably swing).
> that this has already happened, several times.

I'm not following US politics close enough to know anything about it. But why should the democrats try to push an person into power which might have memory problems caused by age??
There's an old adage in screenwriting: Don't give the audience 4, give them 2+2. This is the Kuleshov Effect [0] for scripts.

By giving them the little details, you engage the audience (well, most of them) and make the work more compelling. Medical and Crime procedurals are this in spades. Sherlock Holmes is still idolized.

Educational genres are explicitly against the Kuleshov Effect. The whole point is to get to 4. The audience is not exactly unengaged (video games are engaging by definition), but they aren't drawn in. There are no compelling mysteries or 'flaws' that they help solve with the story of the game. Just a computer holding back an answer.

The original Sim City also comes to mind. It teaches a lot, but is still fun.

Hopefully it doesn't? That would be poor design. It typically is just on a network segment that the firewall rules allow it to access the other servers.
You're confusing general purpose scripting languages with adventure game engine scripts. The latter will literally have commands for moving characters, starting animations, dialog, etc. They are intended to be usable by non-programmers, and might be implemented in something like Lua.
Show HN: Analytics Setup Guidebook- Explaining the Confusing Analytics Landscape
HDBaseT has somewhat consolidated the HDMI over twisted pair market, so you do have one more standard, but it replaces a dozen non-standards in the field.
Hey folks,

Have you ever tried building a simple analytics stack for your company, yet not sure what’s the best way to start with “just the right amount of effort” that can still scale it up later when you grow? And when you went googling you soon got confused by the conflicting advice on the internet: ETL or ELT, data warehouse or data lake, SQL or OLAP cube, etc?

That’s a common problem that I saw when speaking to our customers. I soon realized that books about data analytics are quite outdated given the current pace of development in the space.

There isn’t an up-to-date, high-level “map” that gives readers a proper framework of thinking about the analytics landscape. Much of the materials out there are step-by-step how-to based on a pre-selected set of tools/technologies.

We decided to write that “map” in form of this short book - “The Analytics Setup Guidebook”. The book aims to give readers better clarity over the confusing analytics landscape.

It covers:

* How does a simple, yet scalable analytics stack look like, and how you can build one cheaply and quickly

* ETL vs ELT, what’s the big deal? And why ELT is better than ETL nowadays.

* Why data modeling is important in analytics, Kimball data modeling and how it’s relevant in modern cloud systems

* Why the market of BI tools is so confusing nowadays

* How company’s BI adoption will predictably evolve over time

The book is intended as a comprehensive intro for data people, but data veterans might find chapter 3 and chapter 4 useful — we spoke about how Kimball Data Modeling fits in with modern cloud infrastructure (MPP), and how BI has evolved over time in an organization.

The best part about the book is it’s short, well-illustrated and can be finished within 3 hours of reading!

Here’s a direct, ungated link to the book if you don’t want to give your email: https://cdn.holistics.io/guidebook/the-analytics-stack-guide...

We’ve received some encouraging feedback, but love to hear you guys’ feedback on the book.

problem is not in teachers. Problem is parents. Yeah parents.

Good parents with good parenting skills raise good kids.
Bad parents/single parents - it is much harder to raise kids and give them good education.

if you want reforms - you need to adopt Scandinavian policies in America (high taxes, universal healthcare, universal childare, universal K-12, universal college system) - that way it will be easier to raise well educated kids

Wires don't always work.

If you think wires always work, you've never dealt with the vagaries of SCSI or FibreChannel or even 10gigabit ethernet. Hell Benson Leung became net famous for reviewing all the problems with USB cables (https://kirkville.com/google-employee-reviews-usb-c-cables-o...) let alone the insanity between USB devices (and this was before the whole USB 3, USB 3.1, USB 3.1 Gen 1, USB 3.1 Gen 2, and USB 3.2 fiasco).
First, I think it's super important for anyone working in technology to read, understand, and think really hard about Kaczynski-style arguments like this one.

> If you're making useless things, you have a surrogate activity. We use the term “surrogate activity” to designate an activity that is directed toward an artificial goal that people set up for themselves merely in order to have some goal to work toward, or let us say, merely for the sake of the “fulfillment” that they get from pursuing the goal.

The concept of "surrogate activity" breaks down once you understand human action. Whether in pre-historic African savanna or in modern-day NYC, people always act to improve their present conditions. Humans are different from animals in that we can initiate voluntary conscious action.

Kaczynski doesn't differentiate between involuntary (animal) action in response to stimuli, and purposeful human action, which is not and never was about mere "biological needs."

> At root, it's not about "making the world better", it's about professionals looting the commons to live in fancy bubbles where the only competition is staying ahead of others in the bubble. Hacker News is not the place to say this, as it is difficult to get a man to understand something when his salary depends upon his not understanding it.

Because humans prefer wealth to poverty, much of human action is about creating wealth. You can create wealth without "looting" others. In fact, it's a lot easier to corporate with others, trade, and help each other build wealth than it is to steal.
These tactics might allow coordination in ways which are not allowed under federal campaign finance regulations. Definitely an area that deserves intense scrutiny.

Racism in America and related offshoots of the George Floyd story (for example protests, police brutality) have surely been the most-discussed topics on HN in the last month. You're probably running into the paradox that every story, even the most well-represented, feels underrepresented on HN.
