I have been using IRC since 2006 and I still use it. Initially, I used to hang out on a variety of networks including Freenode, DALNet, EFNet, OFTC, etc. but as years went by I found myself joining only Freenode. The most active discussions around open source projects, mathematics, programming languages, etc. occurred on Freenode.

After the original Freenode staff stepped down[1] and moved to Libera[2] in May 2021, I moved to Libera too.

There are still tight-knit communities on Libera IRC. For example #commonlisp, #emacs, ##math, #python, etc. have great communities with friendly attitude. I have been an operator of the #algorithms channel[3] for over 14 years now. I run a mathematics and computation book club[4] at #offbeat. Contrary to the popular opinion on this forum that IRC is dead, I think IRC is still thriving. It is definitely not as popular as web-based forums like Twitter, Stack Overflow, etc., not even close, but it is there, it is active, and I think it is here to stay for at least another decade or two and possibly even longer.

Yeah, inflation tends do that. The pandemic has been good fuel for inflation and continues to do so, but the fire would have burnt anyways. The fire is monetary policy trying to force growth no matter what. And why is growth forced? Because it's the only way to allow the poor to slightly improve without questioning the endless accumulation of the wealthy.
Pricing at marginal cost is the biggest steal in economics.

Just because one folk who contributes 0.1% to the energy mix has double the average cost, everyone gets to sneak in and get free money.

Specially true in the last winter in Texas where we paid billions to the big power generators only to freeze to death.

The best trick that I have seen happening in the industry is suffocating supply so that the new marginal player just comes in, and then you collect all the extra free money, for essentially selling the same volume.

Good times.
Long Covid is understood better now as an autoimmune disease that comes from even mild cases.

This is in addition to worse damage that occurs throughout the body to any ACE2 cell, which are found in the brain along with the entire cardiovascular system and every other major organ in the body.

117,000 children now living with long Covid
+40,000 more than October

20,000 children for longer than a year
+6,000 more than October

Children crossing 12,000 children have their "activity limited a lot"

You’re right.

I am just curious how one could capitalize off knowing the number of Teslas on the road at any given moment.
Kronecker products have tricky properties and I was struggling to implement a linear algebra algorithm using some of those properties in a way that would be both correct and efficient.

Using the notations from the paper "On Kronecker Products, Tensor Products and Matrix Differential Calculus" [0], I was able to (trivially!) rederive an algorithm called algorithm 993 [1] and then specialize it for our use case [2].

In particular, it let me show that, knowing the layout of the data in memory, some operations could be replaced by carefully placed implicit reshaping of the matrix (telling the linear algebra kernels that it has a number of rows/columns different from the actual one) which are no-ops.

The notation used is extremely specialized and thus useless to most people / for most problems but it turned a complex problem into a trivial one in a way that felt properly magical.

Vaccines don't absolutely prevent infection. By the time the vaccines were out, we were already in a second wave with Delta which dramatically reduced the efficacy. Why should teachers, or anyone for that matter, be willing to risk their health? As a society, we treat too many people and jobs as literally expendable.

You also don't address how children can be carriers even if covid doesn't affect them directly. Child vaccines only recently became available, which reduces the infection possibility and therefore the ability to pass it on. By that time , omicron was a thing and has mutated enough that the vaccines aren't as effective to curtail spread.

The flu is significantly less spreadable/fatal than covid. People bringing this comparison up in 2022 are either wilfully ignorant or disingenuous.

Studies on long term risk to children have just started (1) so numbers are unavailable, but covid has already shown to have long term effects in some children as per my link in the other post

1. https://www.nih.gov/news-events/news-releases/long-term-stud...

All these anti lockdown comments tend to be the same, ignoring network effect and falsely trivializing the risk factor. Comparing to the flu is just ridiculous, and has been debunked over and over and over.

I promise you, it is not the companies who are failing to deliver innovative in education

They cannot survive the way schools decide how to buy software - I.e. district level admins are the only ones with decision making power.
Jira is a monster that does way too much but that's probably why everyone uses it - execs hear of all the features it has without thinking about how the end users feel about it. The Jira replacement will depend a lot on the reasons you use Jira and what features you need.
I think the reason that SMS/iMessage has hung on in the US is that they got "unlimited texting" plans early on, whereas in Europe carriers kept charging per-message much longer, driving people to messaging apps simply to save money. Europeans are also more likely to have international friends to send messages to, which costs even more (you see the same thing in diaspora in the US). Before WhatsApp, I remember Skype was very popular as a messenger since people already used it for free international calls.

Japan is interesting because their feature phones used internet e-mail instead of SMS, but I don't ever recall seeing a client that threaded e-mail conversations like SMS clients ended up doing.
The first thing to do is install Signal on one or more devices and have them sync. When it is on your computer you don't loose your conversations if your phone breaks.

But I agree : no easy backup in Signal is a major pain !

From the Electron based computer version of Signal you can use some js and backup conversations though. (No "restore" option though)
I'm wondering if there is a correlation between the level of bowing to media hype by including cameras and the actual scientific value of the mission?

The recent filming of EDL of the Perseverance rover was spectacular, but a significant aim of that mission and indeed most of the recent mars rovers has been to inspire an interest in exploration and science in the public, a significant part of that is getting happy snaps of events as they happen. The pictures taken were also of significant interest to the engineers involved as they showed events that were extremely dynamic, video being one of the best methods to gain information about the events without impacting the operation.

Web is more aimed at direct science, the products of which will, as happened with Hubble be used to make pretty pictures, which in themselves have limited scientific value, but are of enormous value in engaging the public. This combined with the difficulty and risk of capturing meaningful images given the environment makes live video a non starter.
Also, you wouldn't risk using that ability where it isn't needed as there's always a risk of discovery ruining the whole operation.
I think that is probably a "folk quote", the attribution to Feynman is also inaccurate AFAIK. He said something similar though:

> Feynman was a truly great teacher. He prided himself on being able to devise ways to explain even the most profound ideas to beginning students. Once, I said to him, “Dick, explain to me, so that I can understand it, why spin one-half particles obey Fermi-Dirac statistics.” Sizing up his audience perfectly, Feynman said, “I’ll prepare a freshman lecture on it.” But he came back a few days later to say, “I couldn’t do it. I couldn’t reduce it to the freshman level. That means we don’t really understand it.”

– Feynman’s Lost Lecture by David and Judith Goodstein
Interesting. If academia prioritizes “I shaped” is it fair to say that industry prioritizes “T shapers”? That’s certainly been my experience. Although industry does want deep expertise in one area.

I’ve heard a lot of companies explicitly recruit T-shaped individuals. But I’ve never heard the opposite.
I’ve seen it posted multiple times on this very forum that carriers have not done a good job rolling this out. How is this actually going over in Android-land?
There are a number of techniques available to shrink wasm size in rust, this is the best collection of them I'm aware of https://rustwasm.github.io/docs/book/reference/code-size.htm....

Please also consider Unity web used to be significantly worse and it took multiples of bevy's lifetime for it to get to where it is now :)
It's a wombo combo. Pandemic traps you at home with nothing to do, so you spend more time on social media, where the products are known to drive kids to depression.
Considering how drastic the excess deaths of 2020 and 2021 are relative to previous years, I have a decent amount of faith in the number of deaths reported to be caused by covid.

https://www.cdc.gov/nchs/nvss/vsrr/covid19/excess_deaths.htm
Risk is, by definition, always theoretical. In assessing risk of the kind we are discussing here, you are literally estimating (guessing) two things: (1) likelihood and (2) severity of an unwanted event. So yes, this risk is also “theoretical.”

Now, given the track record of the Chinese government in matters of this type, it is highly likely they will use their legal right and get the information they want/need.

As regards severity, this element is individual: what could be the damage if a particular piece of information would leak? The more sensitive information is, the more damaging the leak may be (and more likely it will be wanted/needed). So if we’re talking about Taiwan, then yeah, aerial imaging information is probably quite pertinent to the Chinese government interest, sensitive or not.

So I’d say this risk is material.

Plus, I have heard plenty of first-hand accounts indicating certain Chinese drone company being very cosy with the Government, enjoying massive subsidies, so likely cooperating without much hand-twisting needed.
Its a precis of a book. It might be, the precis sucks and the book is good? It's on kindle. A bit pricey but I might try it.

I know close to nothing about economics and was a bit confused by this statement:

"The line sloping downwards represents demand. As quantity increases (bottom axis), the price people are willing to pay also decreases."

This makes it sound like there is an "available demand quantity" that is the independent variable and a "price" that is the dependent variable. But it seems a lot more intuitive to say "demand increases (I want to buy more and more people are willing to buy) if a good is offered at a lower price", where price is the independent variable.
Many years ago I asked a question on stack exchange about self documenting code.

https://softwareengineering.stackexchange.com/questions/5130...

I spent many years trying to write my code well enough to not need comments. At the same time I just hit 9 years at my current job and what I’ve come to realise is although the code reads, and makes sense, it sometimes lacks context of why.

So for the last few years I’ve been trying to add brief supporting comments to explain /why/ something was done, or how it ends up in a certain state, etc.

As a result when I go back to that code week or months later I find adding functionality or fixing bugs much easier.

I try not to comment too much or too long unless I really need to.
>2. It's low risk to almost ALL children.

What do we do if their parents end up unable to work due to long term COVID or worse their parents die?
https://data.cdc.gov/widgets/9bhg-hcku?mobile_redirect=true
30-64yo are a significant percentage of total deaths. 30-55 is probably a reasonable age range for parents with dependent children.

>3. Please present evidence of long term effect in a non-negligible percentage of children

You realise we are still going through the pandemic right? There is no long term data either way anywhere because we have to live through it first.
Prompting the obvious questions (which I don't think have clear answers): How much do we think that it reduced transmission? How much transmission reduction is needed to justify knocking a year of socialising out of of a child's life?
Yep, sure, and if that kind of code change was a frequent experience then I can imagine myself thinking multi-cursors would pay their way. As it is, I’d be perfectly happy using hjkl (because the change sites are so close) and cw and . and not for a second thinking my editing experience was suffering.

However, your comments will cause me to take a good look now at VSCodium and https://github.com/mg979/vim-visual-multi
This design still relies on prior stages of the boot process handing stuff over to Pluton - if there are vulnerabilities in the OEM firmware, they're still going to be exploitable in this model.
I think "intelligence" is a squishy, complex thing, and if I have a specific job to do, I'm going to look for more concrete, trustworthy signals than IQ to see who I want helping me do it.
Professors are rewarded for publications and almost nothing else (at least from what I've seen at the school I'm apart of), so because of it all effort goes towards publications, and this passes down to students and the folks they hope to hire. Its also unfortunate any work that is not done towards a publication is essentially invisible to everyone within that system. Even things like teaching are considered second class to publications (very unfortunate consequence).

That being said this is from my experience and am unsure how it is at other schools.
You could use SAR to observe independent of lighting and climate. I’m not sure how good the coverage is right now but it’s improving (see Iceye and Capella). Resolution for car ID though… I’m not sure it’s up to that
*You have to do things from "what we think quadrant IV is" before you realize they're miscategorized.
I found it ironic that this initial quote seemed to be the intent of the article... which then goes on to display charts and equations that are unlikely to jive with a six year old.
What matters, I find, is how you answer two questions:

1. Are you buying for future need and enjoyment, or is the act of buying the enjoyment you crave?

2. Are those things in storage realistically going to see any use in the next year, or do you simply hope they will?
It has a selfie 'lens': NIRcam has extra optics that can be swung in that allows the camera to focus on the primary mirror instead of out in the great infinity.

So in this sense webb is already a camera which can photograph itself!

This capability exists for mirror alignment: They'll point webb at an isolated star, switch to focusing on the primary mirror, swap in optics that cause small phase differences to result in diffraction patterns, and then they can use the resulting images to fine tune the positioning of the mirror segments to a small fraction of the wavelength of light that they're using.
I agree, but this is a tractor. You’d need to hack the fertilizing units or the chemical dispensers etc. unless I’m really mistaken this would just be a device for dragging other stuff around.
He says he works at Citadel in the article itself. It’s a pretty large company in its market, doing rather well.
>Maybe if you're talking Java versions, but not in the desktop OS space. (Look at so many old machines running Windows 7 or earlier right now, and look at long old OSes are officially supported, and how long they're still used afterward.)

>They take their time and meander, and it takes a while. Possibly due to corporate sluggishness, possibly due to wanting to boil the frog slowly, possibly due to wanting to test the waters for a while... who knows why. But speed isn't the main criterion.

But in this case it's not really boiling the frog because it's not really getting worse? All we know so far is that it's TPM but it's easier to update. I suppose this could be used to oppress users by patching jailbreaks faster, but the security benefits at least makes it plausible that they're not doing it as some sort of plan to oppress users.
I start my manual picks at 3000 to avoid conflicts with users created by people like you. (I'm not only making a joke, I really do. My siblings are people like you, too.)
> I think more like 5 [years]

Please drop the hyperbole, there is already enough of an impedance mismatch here. We're talking about slow moving ecosystems, and social normalizing of new technological restrictions. The current locked boot mess has taken oven twenty years to develop since the Trusted Computing Platform Alliance was founded. The pace of change accelerates, but five years won't even make remote attestation available in browsers. I'd say it's at least 15 years until a significant number of websites would require it. Using it for network access control would take further technological development (probably on the corporate side), and then some kind of crisis to drive ISPs/governments to demand consumer implementation. It's worrying because it's a step on the slow monotonic authoritarian march, not because the sky is falling right now.
Agreed. Purple bubbles.

You can get way higher zoom/detail from cheap drones compare to GoogleMaps:

I have no doubt major world powers have satellites that can match and exceed those sorts of capabilities from space, instead of from 100m up, but if you can get end users to pay for it themselves, why the hell wouldn’t you take it.

(Note, that was a DJI drone, and I would have no real surprise if the Chinese couldn’t have taken all my imagery if they’d wanted to. I _might_ have noticed them exfiltrating a few 10s of GB of data somehow, but I might not have as well… They are already geo fencing every single flight it makes, to trigger a warning and ensure I can’t fly over airports (or out the front of my house, since I’m only a few km out one on the flight path from my local airport). I’d hardly be surprised if the drone triggered some other action if someone chose to fly one near/over a nuclear reactor or a military base…
There is a difference between asking “is it a good idea to play in the casino with the loaded dice” and “can that one particular loss be attributed to the loaded dice.” I think the second question is interesting, but it’s not really that important compared to the first question. Naturally the second question is the one that’s getting all the attention from people who want to keep playing in this particular casino. I guess that’s better than just outright climate denial, but aim not sure how much better it is.
I'm assuming that you don't know many farmers, then. It's not universal, but it's very common that farmers are self-incorporated businesses and that those businesses own the tractors. (In fact, this is usually a wise move given how many farming expenses are favorably subsidized by the US tax code.)
Interacting with match.com still appears to be associated with picking up incurable ailments after all these years
To me this is honestly more depressing than climate change and just as depressing as global poverty. We can make sure civilization keeps existing, we can stop exploiting the global south, but even then the best-off people in the world will still often feel that life is not worth living.

I’m glad there are people for whom medication and therapy works. I hope more people can get access to medication. I’m also sad that there isn’t more being done to address root causes.
I'll join the chorus of the other sibling commenters here by expressing skepticism that any medication will at all help with anything.

Psychiatric medication often simply numbs your brain so it stops being worried about things that legitimately and truly torment it. It reduces your sensitivity, it knocks off your normal brain chemicals balance, and it turns you into a robot. I've had a family member go through this a long time ago. It was soul-crushing watching them when I visited. They were almost turned to vegetables with chemical means.

Doing all this does NOT solve the underlying problems that make people reach for suicide. Those problems are societal and very deeply ingrained at this point.

We must look for the reasons that younger people start attempting suicides more than before and try and cure the illness, not the symptoms.

I even started finding it offensive when I see people offering medication. It comes across as: "Here ya go champ, let's again deceive your brain that everything's alright when it really isn't, now off ya go and be a good worker bee, and oh by the way that'll be $2000 for the 10 minutes session". Could it be that we just treat people worse and worse with time? I say yes, yes we do.

But judging by a lot of other replies in this thread, I'd venture to say that many people are not ready to hear it, sadly, and are still in denial, and will shout anybody thinking otherwise away from their platforms (whichever they might be, virtual or in the meat space). And until that changes, the problem will only deepen.
Agreed. When others continue using old threads you’re left off entirely. Everyone has to stop using the old thread (usually be deleting it) for messages from them to reach you. That’s nuts. I’m honestly surprised Apple isn’t been sued for it.
In regards to the media, parents could be more dismissive of the doom and gloom. Instead I watch parents repeat in front of their children that corporations are evil, sea level will rise by 10's of feet soon, racism everywhere, reverse racism everywhere, the China Communists will take over the world, that the U.S. doesn't manufacture anything, etc.

I recall one adult in my entire childhood that laughed off a doom and gloom discussion and one other that said "relax you'll be fine". It immediately paused my chronic anxiety as calm is contagious.
I wouldn't trust such numbers from China. Their death rate has looked like this [1] [2] since April 2020. Coincidentally, that is when covid cases began to take off in the west. China stopped adding to their death toll after they revised their numbers upwards exactly 50% (1290/2579) [3].
