Really cool! A lot of parents had success putting their kids into a learning pod during COVID and it looks like you’re building formal structure around this type of thing.

I love that you’re working on it. If you can figure out how to make this work, the real power of the internet can be unleashed on education… and really just in the nick of time.

Some questions for you:

1. How do you choose the pods? What happens if the kids don’t like each other?

2. What depth is the coach supposed to be able to get into? Seems like a really hard job to context switch rapidly between topics when each kid is at a different place and doing something different.

3. What does the social component feel like? Are the kids mostly building comraderie around broader cultural topics as opposed to learning?
>No one sets out to create programming languages that tie people to their beds.

People can still end up designing such languages, even if they didn't set out with that specific goal.

(Kind of like how you can bring war and division, even if your goal is to bring some religious peace on Earth or "the revolution").

>If people add restrictions, it's not to make users miserable.

That's already explicit in my comment though. They didn't tie the person to his bed to make him miserable but to spare them from car accidents, to help them never get lost, and other such niceties!

The misery is a by-product, not a design goal.
Well there is always dtrace, strace and ptrace.
Are you mentally defining "business logic" as the 20 or so lines of code in a program that are completely independent of all input, output, OS libraries, and frameworks?

Pretty much every app, driver, and framework I've worked on across the web, desktop, and mobile has been mostly glue holding different components together. Choosing a different language would require a nearly-complete rewrite in every case except for a tiny section of independent interesting logic (and of course, if you arbitrarily picked some meme language for your "business logic" you'd have to write more glue code to attach it to the rest of your software..)
Thanks for the link.

Lossless seems hard, but since the concept of 'seed function' is open for everything. It could perhaps use tricks used in other lossless formats.

> Seems like a good opportunity for a contest :)

Primitive seems to be winning for now :D as far as quality of the images :D.

It has some tricks to decide the size, color, shape of the 'seed' it places. At the moment, my algorithm does not really put any effort into that.
Quite an excellent advice, specially for early adopters: we sometimes loose track on what is really happening with sites that were good and just "playful" at the beginning...
I suspect that it's much easier to hear the audible pattern than to see the pattern of a blinking light.
> But who's going to work without AC (other than crazy HoTT people)?

Yeah... Those crazy HoTT people, trying to actualize the goal of putting mathematics on an actually firm foundation and removing the rest of the gobblygook handwaved into the religion of math as opposed to the pure logic it represents...

Also you can use HoTT WITH AC / law of excluded middle... It's just not there by default and there are some really nice things you get without it, so it's pretty much only the lazy crutch of mathematics since forever. If you see proof via excluded middle, consider it a code smell (and recall by the Curry-Howard correspondence the proof is essentially code)
Thanks so much for your questions. To get started, we are talking to parents who have already opted into an online school or even an online homeschool program. Those families have already made the transition to the learning model; and many of them are looking for greater opportunities for socialization and academic support. When we describe the model to them, they see its value pretty quickly.

As you are pointing out, we do have trouble reaching the parents in a more traditional education who aren't actively seeking out alternative options. Our hope is that as we show the value of our model, the word will spread and more parents will opt in. In the meantime, we are doing whatever we can to lower the effort required for families to transition. Any suggestions are most welcome!

Homeschool co-ops are an excellent comparison. For those who may not know what those are, a co-op is a group of homeschooling families who come together (often on a voluntary basis) to support each other with their kids' education and other needs (e.g., meals, childcare, etc.). They've been around for years and, in the pandemic, they started to get mainstream as 'learning pods.'

In some ways, you can see us as making the concept of 'co-ops' more available to more people.
What about negative numbers? Or complex numbers? They are only tools, which can be quite useful to build models of the world with predictive powers but shouldn't be confused for the underlying reality.

Even whole numbers are an abstraction that makes sense only when you can clearly define what is the thing you're counting.
Compiler validation is done by a third party so you cannot claim validation without really passing the testsuite.

All compilers have bugs and releases happen (at least for GCC which I know a bit more than others) with plenty of known open bugs.

Having a testsuite is of course a good thing, however if you take the top 20 programming languages in use, how many of them do have an accepted wide coverage publically available language test suite?

You said "half-finished product" but what about compiler for every other language than Ada of which most of them don't have a testsuite? How do buyer decide to use Intel C Compiler for example?

Remember all of this was in early 1980.

Having this testsuite was well ahead of its time as many things with Ada, what I'm trying to say is that it didn't play well at the time to help the language ecosystem grow.
tough opinion: As a blue-collar worker, im glad they cant get into college.

Im sick of seeing talented kids that can solve difficult problems and work hard, submit themselves to a meatgrinder that promises them wealth and success and instead shackles them to endless debt until theyre dead for a peasant wage at the local burger joint.

If the schools tell you to pound sand, come work for us in trade. We need welders, machinists, mechanics, HVAC, plumbers, electricians, and ironworkers. Youll tackle some of the hardest problems and at the end of the day feel like you did something you can be proud of. Our wages wont move you in next to ole Musky, but theyre enough for me to comfortably own a home, a car, and two motorcycles.

talk to your guidance councelor or local trade-tech college and ask about the opportunities outside the walls of a college sports team masquerading as an undergrad education.
I didn't mean that they took it personally. That wasn't my intention. However I've often just commented "I can't wait to get to office again" and received downvotes and hostile comments on HN.
Show HN: We built an end-to-end encrypted alternative to Google Photos
Hello HN,

Over the last year we've been building ente[1], a privacy-friendly, easy-to-use alternative to Google Photos. We've so far built Android[2][3], iOS[4], web[5] apps that encrypt your files and back them up in the background. You can access these across your devices, and share them with other ente users, end-to-end encrypted. You can also use our electron app[6] to maintain a local copy of your backed up files.

We've built a fault-tolerant data replication layer that replicates your data to two different storage providers in the EU. We will be providing additional replicas as an addon in the future.

We're relying on libsodium[7] for performing all cryptographic operations. Under the hood it uses XChaCha20 and XSalsa20 for encryption and Argon2 for key derivation.

We have documented our architecture[8] and open-sourced our clients[9].

We did a soft-launch on r/degoogle[10] sometime ago, and have since then ironed out issues and polished the product.

But we are far from where we want to be in terms of features (object and face detection, location clustering, image filters, ...) and user experience. We are hoping to use this post as an opportunity to collect feedback from fellow hackers.

If there's anything we can do better, please let us know, we would like to.

Best,

- Vishnu, Neeraj, Abhinav

Judging from history, ever worse than we do now.
How is that even possible on Reddit? You can configure Automod to remove comments by users but AFAIK you can't make it visible to friends.
As computing environments mature, a lot of the instrumentation that used to be presented to users has been going away. I do think that's too bad. One of the first things I install on any new machine is a visible network/CPU/memory monitor.

Humans constantly monitor their environment, and tend to only become conscious of something when it is behaving differently than it had been. Think of long drives - unexpected motions, odd noises, etc. trigger conscious attention.

Computers, especially of the 'cloud' variety, lack the incidental physical environmental interactions that give us those, so intentionally building them in is required. (And because they're intentional and artificial, they're at risk of manipulation, something else to worry about.)
you can have both and put a sound and/or light trigger to the logs with a grep and a tiny script.
War for Dharma, and you perfectly know everything can be called dharma in Hindu religious texts. Cleaning toilets, dharma for the subjugated caste Hindu; worshipping god - dharma for the dominant caste Hindu; fighting territorial war - dharma for the kshtriya. Dharma is central core of bhagvad gita and which renders it ambiguous and yet attractive to certain people. Define whatever as your dharma and you are on your way to do good.

Modern Example: Steve Bannon was defined as Dharmic warrior by Indian Consul General to US.
Thank you for that insight about New Hampshire!
"starting" is ambiguous. I really meant "getting to work".

Thinking about new things and maybe throwing down a few ideas is indeed easy and pleasant.

But deciding to spend a few hours to move a project (instead of not) is what the brain hates. It hates commitment, and is very afraid of the opportunity cost.

> If having access to the machines means that you can affect the results of the elections

They disabled the security cameras and did something with election equipment, which is now set aside as evidence.

They need to investigate. This would have happened if it was a paper voting machine or a ballot box with votes in it.

This isn’t a “conspiracy theorists are correct” moment. This is a show that the voting system does indeed have protections and supervision around it that identities tampering and resets the supply chain.
This is a purely emotive metaphor with no technical content?
the frequency range of pulsing audio is much higher than pulsing light thats for sure. sound was used a lot to calibrate analytical instruments in labs. throw a frequency divider a tiny amp and a tiny speaker and you could easily find if your frequency is stable, drifting...
How can we make CTOs better? How does one CTO learn? How a community of CTOs can help create value to one another?
This isn't arguing against the consideration of sunk costs as fallacious. It's just arguing that when considering reputational and psychological costs, a lot of what looks like sunk cost fallacy really isn't.

Needlessly provocative headline. It is still fallacious to explicitly consider unrecoverable past costs in future decisions. It may be reasonable nonetheless to attempt to quantify the cost of a hurt ego from admitting you were wrong and use that to make future decisions. Ideally, you'd learn to get over that, but if you can't, so be it. Maybe we need mandatory education programs to include some element where kids are forced to fail so they can learn to get over it. Play sports. Do something, anything, that humbles you.
Yeah, 5 positions in a day in the US would be extremely small. My November ballot had 10+ candidates and 10ish questions/propositions.
Message queue (i.e. RabbitMQ) sounds like a more natural fit for your problem.

What is the peak and avg QPS you need to support? High peak QPS might force you to introduce distributed workers and makes locking impractical.

Another consideration is how much do you care about data integrity. Would it be a problem if a few messages are lost? What if a message for processed twice? What if servers lost connection to db for a few seconds? What if a whole server/db goes down?
No. As with everything else in life, context is important. One can easily just read it and then proceed to justify their doings using it if they either don't know or choose to ignore the context of it.

Whole of Bhagvad Gita was spoken during the Mahabharata War. It contains some overall guidance i.e. it can be applicable to normal day life as well as situational guidance on the context of the going war.
I was somewhat involved in this process at an org I worked at, the thing is, some languages really are the best tool for the job, and trying to build something in the wrong language can really hurt software quality or reliability. That said, I agree you should still try to standardise to a reasonable degree.
Look into the research behind melatonin use. I’m not a doctor and certainly long term use of diphenhydramine is associated with neurological problems in old age, but I’m not sure melatonin should be used as a simple hypnotic as you are suggesting. It’s natural but so is testosterone. Hormones may not be good to tinker with. I say that as a long time user of melatonin. At the very least you may want to stick with lower dosages- nothing over 1mg which is about as low as is easy to find.
I cut the relevant part since rest is obvious hyperbole.

But since we are on the topic from my experience most of the crashes that involve bicyclists could have been easily prevented by the cyclist.
> A key photo - later known as "the Hogmanay image" - showed one of the two ringleaders, Neil Strachan, 41, attempting to rape an 18-month-old boy whom he was babysitting on New Year's Eve.... In October 2009, Strachan was sentenced to life imprisonment with a minimum term of 16 years, cut on appeal to nine years.

Just 9 fucking years for abusing an 18-month old child?!?!?? What is wrong with the authorities there?
> The conspiracy theorists caused the breech - the Mesa County Clerk is the one that c illegally copied the voting machine hard drives and gave the images to other conspiracy theorists.

Back when voting machines were made by Diebold and the conspiracy was that they were tipping elections in favor of Rs, this sort of thing would have been taken as absolute proof - by the kinds of people who are today trying to play this all down as not concerning (I guess because it's a contrived or unlikely attack) - that we shouldn't use the machines and that election results could reasonably be doubted.
Yeah, it was a comment on the title. I'm sure that the professional criminals / pedophiles that produce this stuff, are well aware of the various inferential methods used to catch them.
Agreed, this would be the main concern, since it's one the things people hated about the PS4 and PS4 Pro (being really loud). I don't think Sony would want a regression there either.
VERY good catch, was confused too.
What do you think of scrapping the perceptual hash and reorganizing those resources for an initial effort of catching ONE perp. Just one, a case to see what it takes to get the evidence together for a conviction of the actor, not a “ring” of file swappers. I’d find that much more satisfying.
Maybe every video can be scrutinized. What about the bedding or linoleum on the floor has appeared in other videos? Maybe the carpet is only prominently available in certain countries.
With humans, this is known as 'area denial', and is also under active research.

> It's a shame phpbb, vbullettin and other big players in the space were too slow to adapt to mobile.

Was that a problem? My memory is that everything used 'Tapatalk' for mobile, perhaps before the first iPhone even (I recall using it on an iPod Touch).
I miss being able to know if my program is frozen because of CPU (fan noises), disk access (HDD noises), or network (silence).

I've thought of "reimplementing" that for troubleshooting my own projects. Imagine `clang --sounds`, so that it makes a sounds when

- Accessing disk.

- Sending something on the network.

- Allocating large buffers.

- Waiting for locks.

Or, alternatively, there's a constant background sound that is modulated on every function call depending on

- Call stack depth.

- If it's my code, library, or syscall.

- How long the last call took.

- Or just a unique modulation for each major function.

I think that's a nice, easy, and useful step before the more advanced applications mentioned in TFA.
I have lived in Munich for about 15 years. It is has 28.5% foreigners, making it one of the most diverse cities there.

It‘s possible that you asked someone who chose to be a ****. But most people there are helpful.

Here is the communal election 2020: https://www.wahlen-muenchen.de/ergebnisse/20200315stadtratsw...

AFD got 3.4%. The conservative party got 25%. 28% combined and lumping them together is already too much.

> I travelled for work or vacations in all the countries in Europe […] I never had a communication problem outside Germany

Have you been in Spain outside of the touristic centers? How about France? Not everyone there speaks English and if I go there I try to adapt! I have struggled, I sometimes had to resort to another language, I sometimes couldn‘t communicate at all. But I make the effort because I‘m coming to their country whether on a vacation or for work. I don‘t go around complaining.
This more-or-less describes the Canadian system as well. We get “voter cards” mailed to us that make it easier to look up the person on the voter rolls, that’s the only notable difference. And they aren’t required, similar to what you say.
If anyone is curious about good versions of the text, or about the Mahabharata in general, I recommend Bibek Debroy. His 20 volume Mahabharata is very well written, and includes the Bhagavad Gita. However he has other translations of the Gita in and of itself. They're all worth a look-see.
True, oil is processed food. By that same argument, all cooked food is processed.

The animal fats I eat are from my own farm, processed by me, lard rendered by me. I realize not everyone can do this, but quality control (and lack of preservatives and other bullshit) is much easier to do when you're the one doing the cooking.

Just like roasting a chicken yourself is making "processed food", there's a big difference between that and, say, getting some chicken from Chili's, or some canned whole chicken.

When I speak of "processed foods" I guess what I mean is highly processed foods, usually processed in factories, surrounded by incentive structures directly opposed to healthful food production (because it's invariably more expensive).
That's basically what I had thought (I'm the grandparent poster), and I had included a definition in my post to try and make it clear what I meant.

As a sibling post pointed out

> This only applies to gnostic atheism. An agnostic atheist like me admits to not knowing if $DEITY exists but does not believe in the absence of compelling evidence.

So it seems like there are different flavors of atheist.

But you can also see the other person that answered my post with a rant about how god doesn't exist and science won. This vocal kind of atheist is what I was calling "religious"
This alludes to a concept I've been wrestling with: "hard" versus "soft" understanding.

A professional in _any_ industry will pick up a notable difference between extremely similar states. This article is expressing the fact that older computers were easier to read.

I'm convinced it's a product of sophistication. Distributed systems used to be an enterprise thing, but now everything is technically a distributed system. Memory registers are quantum scales more than they used to be. Drives now have no moving parts.

There are still ways to get an intuitive understanding, but they're...different, and certainly not audible. I've noticed that I can feel out I/O speeds when I'm power-using. I'm fairly convinced that many knowledge workers prefer a specific OS because this intuition pulling up false-positives in a new environment.
And in Rust you can always drop down to reference counted heap allocated stuff as well.
You are not alone and this is not unusual. I don't think the Western world has quite figured out how to transition people to a successful adulthood. Or if that is something we are supposed to do cold turkey. It takes a village right?

My mental health deteriorated too. Looking back I should have built a support network and gone to therapy.. a lot of therapy. This all hit me at the end of college and in grad school. So I was broke too.

I didn't really have family to fall back on either, I was lonely and felt alone.

I'm still working on it, despite marriage/kids etc... I actually wish I had capitalized on my alone time in retrospect. Hence therapy!

>Regardless, I don't believe I'll ever feel the way I once did about this world.

Do you want to feel that way? What you have now is perspective and you know more about yourself.
You can certainly imagine going faster than light, but that doesn't mean it's possible. Saying it could be possible is basically saying "our understanding of physics could be wrong". Technically correct, but at that point we aren't having a productive discussion. "Assume everything we understand is wrong -> we can now teleport"
The really frustrating part is that a trivial edit--ask for the average temperature instead--could make it into a sensible question.
Saving weight probably saves some money in transport, materials and assembly. If this saving is made to offset raising component prices all the better. Once a homebrew becomes available models with a bigger cooler might be worth more though.
This is a common thing no?
The word 'dictation' is confusing here. I think you want 'recitation', 'vocalization', 'narration' or just 'reading'. Dictation is speech-to-text, this is text-to-speech.
The JVM more or less allow you to do that. Its debugging and profiling abilities are amazing. You can also do most of these things (and more) with the various tracing systems of the linux kernel. (edit: typo)
