I second the use of Anki--it's a great tool. Other (non-free) options include SuperMemo and IDoRecall.
If you go back 100 years that includes World War II…
This is really great. I especially like the idea of online tutoring (for languages and other stuff) which looks to be a nice cheap option [0].

One piece of advice that I think is actually quite bad, or at least I've had extremely bad experiences with, is asking people for something. I've often cold-emailed artists, programmers and other hobbyists asking them to make their work libre/free (artists CC-BY/CC-BY-SA/CC0, programmers GPL, hobbyists some type of OSH or CERN license) and I don't think I've ever gotten a positive response. The only exception is when I haven't read the documentation in depth and the project is already libre/free.

Most times, asking artists or others to put their work under a libre/free license, even if it's decades old, is met with outright hostility. I usually try to couch the "ask" in passive language and signal understanding if they don't want to but, from my limited experience, this only seems to make people angrier.

I'm sure there are better ways that I could ask and I'm sure I'm framing it in some way that triggers anger but I also don't think there's an actual good way to ask that from someone to try and get them to put their work under a libre/free license.

Talking to people in person is another matter and that I've had good success with, but asking online, through email or otherwise, often ends in them ridiculing me and calling me names.

Because they want you to do 10x the work for 0.8x the pay?
Then the solution is clearly to reduce scale where possible.

Many of the things that scale is being forced into don't actually increase their net benefit to the people with scale (usually it is the opposite when you consider the requisite slavery/coups/wars/etc. to provide the infrastructure and labour), merely the amount that can be extracted by some centralized entity.
Well said. I certainly agree with this. It is a good approach into understanding what works and what doesn't work in crypto and what would most likely happen in the future. What I think will happen is quite simple:

Not all crypto projects and their technologies will survive, a few of them will stand the test of time especially when regulations do come and all of them won't be completely and 'totally destroyed' as the anti-crypto folks keep saying that 'all of them must be destroyed'. They also won't overthrow and 'replace the current system' as the crypto-maximalists keep saying that it will.

The hint in seeing which ones will survive are the ones that aim to co-exist with the current system. Take this from Stripe [0] and Moneygram [1] and Checkout.com as good examples of all of them using a stablecoin like USDC for payments. I'm sure they all waited for regulatory clarity before implementing these projects. It is not what either camp would want to see, but it is what is really happening right now, even for the case of some of them with CBDCs and the ISO 20020 standard.

> Most pro-crypto and anti-crypto have attached their identity to liking or dislike crypto.

Exactly. This is the problem.

Either you have those who have invested heavily in the coin so they need to keep shilling it on social media or you have those who make a living or gain a following disliking all of crypto on social media or even selling books on why it will be destroyed. What's definitely common with both extremes is the attachment of identity to either camp which does bring out the most irrational and absolute claims and predictions seen with a very high chance of them being both incorrect.

The only absolute that exists is: There are no absolutes. When either side continues to make absolute claims, they will realise that they will be disappointed with the actual reality that is being shown to them doesn't match their utopian goals and absolute beliefs.

Ask HN: Need a simple barebones static landing site service for a charity
Ideally, would love something along the lines of Netscape Navigator browser's "Composer" which has been duplicated in SeaMonkey ... but without having to micro-manage things like cell border widths and such.

The closest thing found so far is Carrd, but it doesn't seem to allow for the flexibility of Composer.

Basically, need something that effortlessly allows a "WYSIWYG"-type approach to having a single, static landing page with the ability to add a little bit of text, an image or two initially, and the ability to maybe add more images on the landing page OR have a separate "Partners" page where corporate logos and maybe some contact info for a key person could be added.

Pretty much everything so far is overkill, insists on flashy "pre-built templates" that take away from the core presentation and don't even allow for the "look-and-feel" desired.

At the same time, hiring a web dev, even on outsourcing sites, seems a bit too much PLUS maintaining control of all aspects of the site would be crucial for security purposes.

Thought about Facebook or Reddit which WOULD allow for group communications, but have had horrible experiences with both where previous accounts/subreddits were banned "by accident" for technical reasons that the companies agreed were in error, and yet have inexplicably failed to be of assistance in retrieving the data lost, despite agreeing that the accounts/subreddits were flagged "by mistake" via automated processes they developed but refuse to take responsibility for ("It's not OUR fault, "the Ai" did that" ...)

Anyone have any ideas?

I've looked at "landing page" services, but again it seems like overkill with too many things that have nothing to do with what this project is about, and again most of them seem to have this insistence on dime-a-dozen "templates" that clutter the presentation and have nothing to do with what is actually desired.

tl;dr: Looking for a simple WYSIWG web-based service that can (preferably automatically, linked with domain name creation/integration/management) publish a 1-2 page landing site with the ability to edit minimum text and flexibly add photos of partner companies as they sign up.

Thanks in advance for any suggestions.
This is convenient but having the kernel block on userspace doing something is typically bad design :(
Like it or not, it is true. As reliability and performance of automatics gets better and the gas mileage is now also on par and the cost to produce an automatic is reduced by economies of scale, manual transmissions are going by way of horse and buggies. It’s not everywhere but it will be.

Also consider that EVs have different requirements for their transmissions than ICE vehicles and there are no EVs with manual transmissions as far as I know at all.
You do realize that socially imposed norms about what topics you talk about, in what context, between whom and how has probably been the norm for longer than written history?
I think that POET Technologies is in the same space and also has 400G
> But you are allowed to do that!

Things you are allowed to do +1

Thanks. Even though you are the first person who tells me this. Plenty of career workshops say the opposite.
The problem is that people can’t actually take over fast enough necessarily. If you’re not actively driving, then you can’t just immediately react.
> People need to live somewhere, every day.
> we can't all make US minimum wage and afford SF rents / home prices.

This is true. SF also has one of the worst homeless problems in the first world.

It’s easy to think the problem will be confined to a few particularly bad cities and things will stay balanced at a lower amount elsewhere. The reality is there really is no reason it won’t become the standard, or even the minimum.

Home sellers and landlords are demanding increasingly ridiculous prices and they’re more than happy to let properties sit empty for years than they are to lower prices a single dollar. I’m not sure if it’ll be resolved so easily.
As a kind of middle-ground: CI/CD burns our abundant cycles out of band. That’s a good place to spend extravagantly.

I’m all for burning more cycles on tests and static analysis and formal verification etc. before the software goes on the user’s machine.

But we all live every day with “good enough” on our machines every day. I think there’s a general consensus that too much software spends my CPU cycles like a drunken sailor.
I'm a successful engineer. I hate JIRA. I like keeping docs up to date, but if you're gonna make me deal with JIRA's BS just so I can do a quick doc PR, guess what, no updated docs for you.

Where was the value created again?
By keeping pointers to the content rather than the actual content ;)
Yeah, I recently disabled all location services on my M1 Mac mini after suffering over a year with constant wifi dropouts, not even poor latency but just no network for a few second every minute. Not sure who at Apple thinks this is an OK experience.

Generally their network stack is a mess. Trying to bridge ethernet to wifi just fundamentally doesn't work. The forwarding is randomly reconfigured every time the machine wakes up. I think they aren't paying attention to system level functionality.
Covid recovered aren’t having same problems as vaccinated when it comes to heart problems.

I had long covid 14 months and never heard of myocarditis on forums before the shots. I had chest pain for a while but it was not permanent damage. Myocarditis is permanent damage.
I have a text at https://hefferon.net/linearalgebra/index.html. It is aimed at beginners. It comes with perhaps two dozen exercises per lecture along with complete worked answers to every question, with videos of the lectures, a lab manual using Sage, and some other ancillaries.

Like others here I recommend 3B1B, which may be what you are looking for visually, but whatever you end up with it is absolutely crucial that you do exercises. Do many of them. It is the only way to get better.
At my startup, every new management hire thinks they can improve our process by introducing scrum.

Every year we make another attempt at it only to find out that it isn't agile enough to keep up with the pace of the business.
The linked page does not ignore fossil fuels, but shows, that the impact of the animal agriculture is under-estimated. If cannot focus only on fossil fuels and ignore meat production, if we want to reverse the current trend in a reasonable timeframe.

"The burning of fossil fuels is currently the leading source of human-made carbon dioxide (CO2) emissions. However, climate change is caused by cumulative human-made greenhouse gas and aerosol emissions and not just current CO2 emissions alone. While humans have been burning fossil fuels for a little over 200 years, we have been burning down forests for animal agriculture for well over 8,000 years."

"We show that we need to transition to a global plant-based economy first and that blindly eliminating fossil fuel usage first will accelerate the warming of the planet."
Arguably signals were the classic "upcall", and netlink is probably main mechanism for upcalls in current linux.

But NT's hidden VMS-esque API for upcalls would be somewhat nicer option at times (or Solaris Doors)
I suspect one problem is that the people who are high enough to be bringing in senior+ contractors have often been at the same company for a while themselves and may not realise how quickly their impression of the rest of the industry can become outdated. I had a discussion with someone not so long ago who was very senior, basically running all of software development in a tech business well past the early startup rush phase, who told me quite sincerely that everywhere did daily standups and worked off a Scrum-based process these days. This was someone who I respected for being smart and open-minded about most things, yet they had this intense blind spot about how tired Scrum and all the rituals that come with it are looking to a lot of good developers now.
It isn’t really that bad until the end, FWIW. Mostly. The D.C.-based author is apparently writing a book titled Palo Alto; I bet we’re gonna love that one...
Take notes about the most important parts of what you learnt. That way when you have to recall a topic you don't have to reread the whole book or tutorial but just your notes.
It's still possible to pace the GC like this in certain cases, but most specific benchmarks before the preemptive scheduler introduced in Go 1.14 aren't particularly relevant anymore. Today I think that Twitch blog post does more harm than help. (And even at the time, while an interesting case to analyze, the right fix is usually "make less garbage", not "add some ballast".)
Essence of linear algebra is an absolutely wonderful series. It gave me an intuition of the subject in a matter of hours in way years of university didn’t do.

David Gelernter is a whole other piece of work. He did co-author a pretty good textbook on parallel programming (_How To Write Parallel Programs_), but the guy was basically a huckster when it came to distributed systems research. The real ironic thing is that it can be hard to tell Gelernter's Wall Street Journal op-eds from Kaczynski's manifesto.

I bought FSD version of Model 3 in the spring of 2020. I'm still waiting for what I purchased to be turned on. Frankly, I'd be psyched if they would expand on the little things instead of the big things. "Park the car in that spot". "Exit the parking spot". These would be worth the price I paid.

Doesn't fit "the narrative"?

Not complaining ( which is not permitted by the rules). Just asking.
Holy shit, I’m hiking with this guy right now on the AT!! This was a two-year COVID passion project that Andy made with his brothers (one coded it, the other made the music, he designed all the pixel art).

It’s SO cool to see this on here. I’ve been tracking him using it when we get separated. Andy, if you see this, hello from Deadweight :).
Actually, lots of circuits can be built with components specified to within 20%, perhaps with some key components specified more tightly. Good designs are robust against component variation.
I heard that conscripts used to draw straws to see who would get deployed to those islands because of the chance of artillery landing.
Yeah, these are commercial signage displays. Compared to average retail models, these tend to have thicker, sturdier (and much heavier) housings, higher brightness, more resistance to burn-in, better heat dissipation and a dizzying array of inputs. Most of which is entirely superfluous for home use, but they can actually be worth the money. They're also typically sold without stands but will have VESA mount points.
I don't understand though how a "network scan" (I assume sending a broadcast packet and receiving a response) can raise ping time from 3 to 150 ms.

A future with high powered infrared lasers on top of every car will probably lead to a mysterious rise in people slowly losing their vision. Someone should do a study of the eyes and vision of people who work with LIDAR.

Why not instead use multiple radars (we already put 1-2 radars in cars with adaptive cruise control) to augment Tesla's vision based approach?
Dealing with this right now actually. We (a start-up) got bought. The product was split into two teams - we originally did BOTH HW and SW. Their HW team was pretty good so we let them do the HW and we did the SW. The problem can from the HW actually being HW + FW (a form of SW) and turns out they are mediocre at best FW and digital design and that's become a problem (we have to hook into what they are doing).

We (the original startup crew) finally figured out what the problem was: their commitment to ANYTHING (our HW project but also every other product they've ever worked on) is exactly the same as how most people treat school and homework, namely, how much can get away with NOT thinking and doing about it and still get a passing grade.

They can't be "fixed" because that's how deep the problem is: they've been trained for this attitude since they were children and they wouldn't know how to break out if their lives depended on it; they are not dumb or low-IQ. But they've been trained to achieve the lowest-common-denominator of anything they design or engineer.

This has never been how any of us have approached anything in life. For us, it's:

1. Do the best job regardless of what you could get away with

2. Focus on the big picture and little picture integration

3. Know who actually makes the product a success: the customer and the market

Significantly IMO I went to elite schools on merit rather than legacy/money while my co-founder was home-schooled and didn't actually finish his BS but he has more drive and commitment than 99 out of 100 BS EE or CS degree holders I've ever met or worked with.

Most people mouth the words but either don't actually know what they mean or do not mean what they are saying when they say them. This may not be sufficient but I think it's a necessary difference between normie engineers and 10x engineers.
Personally, Taiwan's most important mission now is to continue maintain TSMC's superiority over either China and US in advanced Chip manufacturing.

Once TSMC lost that advantage, either side of China and US are going to put Taiwan in a much lower significance in the consideration of their own duel of power.

The one being treated the worst is always the one who is inconsequential. The bad guys are never target of so-called justice...
This goes to show why Activity Monitor is such a great tool for troubleshooting and killing suspicious processes that hog resources.

Same problem. Speculative failed authentication speculatively traps, speculative successful authentication accesses data.
Asking for something is not the same as asking for free stuff. It’s especially not the same as asking someone who is trying to make a living creating things to just start giving them away. It’s not surprising to me that this kind of suggestion is met with hostility.
Quality is costly in time and money, but to your point, it’s not mysterious how to achieve.

I write slow, half-assed Python scripts every single day, because “good enough” is in fact good enough for some things.

But over-extrapolating the “good enough” mindset to everything is lazy and makes computers less fun.
I used the BSD version of this (which seems the same AFAICT) a few times years ago and managed to misunderstand the output a few times and gave up. I doubt it was an actual error in the conversion but the UI is comically bad. The typical search engine UI is great, ask for a conversion using whatever abbreviations you want and it gives you a detailed explanation of what it thinks you asked for and the result (and not some other number you didn't ask for). I see GNU units at least has a -1 option to just give the result.

Firefox has a hidden simple unit conversion tool that can be enabled by setting browser.urlbar.unitConversion.enabled to true. It only has a few conversions, though, and doesn't give much detail about what it thinks you asked for.

It looks like there is a rust unit conversion utility called rink that seems better although, like many rust utilities, it lacks a man page or any local documentation besides a brief --help message (there is an online manual). Some units are a bit annoying; you can't just do c to f, only degC to degF (and not even degc to degf either). But much nicer than units and can also be easily be used as an interactive calculator.

https://rinkcalc.app/

Edit: Playing around with rink a bit more it has some neat stuff. It gives info if you enter a unit (or constant or substance), usually defined in terms of the base unit of each type but if you give the base unit it has a brief text explaining how the base unit is defined. "c to f" not working is because it doesn't use context and c is the speed of light. You can use 'units for' to see available units for a particular type, although it doesn't look like you can show all available units other than checking the source (based on the GNU units definitions but with some differences, such as degC). It suggests a supported unit if you type one it doesn't understand.
There was some debate three years ago on whether insect populations were declining, with the prime suspect being modern pesticides.

The most solid data source they found in Germany was a local club of enthusiast entomologists who had been collecting bugs using the same traps, locations, and methodology over the past 80+ years.

The answer btw was yes, there was a marked reduction over that time frame.
I'm very sorry for what she, you and your family are going through, I really hope she'll be OK.

We [1] are one of the companies who are trying to make "this" happen. "This" meaning: providing a holistic, complete health record for patients (including appointments, radiology, lab results, etc.). It is not trivial: one of the largest failed IT projects in history is the digital integration of various NHS systems (https://www.theguardian.com/society/2013/sep/18/nhs-records-...). Our goal is to provide patients complete access to and full control over [2] their medical data. So we're in the process of building what you are proposing, but it's not a fast process.

It is primarily not a technical problem -- it is a problem of trust, coordination, aligning incentives, legal issues, etc.

I don't know about easy, but there are plenty of good sites left if you don't have a blanket ban of around a mile around every hamlet. And it'd help if the approval procedures for new construction wouldn't drag on for years and years.

These things aren't part of the physical environment, they're political realities. Are they fixable? I doubt it, like I said above, if people haven't got it by now, they never will. In the long run, Germany doesn't matter anyway, that's the good news.
