Not quite as wild, but there was a similar thing in Sweden 50 years ago, where an oil burner was retrofitted to the cancelled nuclear power plant at Marviken: https://en.wikipedia.org/wiki/R4_nuclear_reactor . The reactor, which was more or less completed but never loaded with nuclear fuel, was used for various experiments related to reactor safety.
You've almost certainly never had a job that paid what your labor was actually worth. Most would replace you with a computer program the second they they could. Don't feel bad about stealing an hour of time to get your teeth cleaned.
Yep. The BBB bill was just an offering to appease their big $$$ donors. It's political theater at best. Contempt for their constituents at worst.

Coffee shop I used to work at made the conscious choice not to have any customer-accessible power outlets, so people were limited by their laptop batteries. I was told when they built the place, they debated between offering free wifi, or having plugs in the cafe. They ended up offering wifi, but no plugs. Seemed to work pretty well, I don't remember there being a huge crowd of people staying long. Although it was also a small shop with fairly limited seating.

Although, that plan is faulty now, given that I could easily get 6-8 hours of work out of my Macbook, thanks to the M1 chips.

> you probably didn’t know what you doing using C#

Maybe. I was using a NuGet package recommended by the senior dev (that the team was very familiar with) but with Go, I decided to write everything myself.

One could argue it's not a great comparison but I think it is. The main point of comparison was using solutions/languages that the team is familiar with versus exploring something new or different.

> I don’t mean to be rude

No offense take, I don't think I'm better or worse than any other average developer.
"Theoretically could" is practically useless without providing a reasonable route to actually happening. The US could theoretically nuke ever major city in Canada, bit that possibility is ingored for almost all practical purposes (and the purposes for which it is not ignored look at the reasons why it would happen.)

Eliminating a species of mostuito is expensive and additional effort breeding and releasing mosquito's for each species you want to eliminate will always require additional work and effort. Why would we expend that effort to eliminate a species that doesn't bite us?
<3 SCIP. About a dozen years ago I used to write the python-zibopt library (now defunct and rendered moot by the far superior PySCIPOpt).

Hadn't heard of JoD - that looks really interesting. What are your experiences so far?
Glad I can help! I always like teaching people about space stuff (that's obviously the technical term we use in the aerospace industry).

There would still be some serious engineering to have some sort of meaningful electronics (even just a comm beacon with a heartbeat) to survive that impact. A closer analogy might be trying to stick a piece of gum to a supersonic aircraft.

Lets take the Deep Impact as a reference starting point. From the mission data info on Wikipedia [0] the impactor collided with the comet at a relative speed of 10.3 km/s (23,000 mph) and the impact energy was estimated to be the equivalent of 4.7 tons of TNT. Getting something to just straight survive the impact is going to have to be really really tough.

The other option that I am just spitballing (many puns intended) is to get something that would hook the asteroid attached to the payload at the end of a very very long spool.

Step 1: you get the hook in to the asteroid/comet. This has its own challenges. The surface of asteroids and comets is often just very fine dust and small rocks (regolith) attached to the asteroid by it's own small gravity. So perhaps a gigantic net would be better, but again it still needs to be strong enough to survive that initial impact.

Step 2: Attached to the net/hook is a very very very long (like probably hundreds of kilometers long) spool of a very high tension wire that you start spooling out. Again this has to spool out at the relative velocity between the two objects. So something very low friction and probably some sort of active cooling radiator in order to take away the heat. There are missiles that spool out wire behind them to the thing that fired for guidance, i'm envisioning something like that but even crazier.

Step 3: The velocity of the spool starts gradually slowing due to the friction and the relative velocity between the asteroid and the probe. And eventually the probe is being pulled along behind the asteroid. You probably also need some sort of independent thrust and control system on the probe to prevent it from flying around wildly behind the asteroid or possibly smacking in to it again as the spool whips you around.

Step 4: Realize that for all of this effort you are only really traveling about 3-4 times faster than something like New Horizons and its still going to take you 4000 years to reach Proxima Centauri (the nearest star to the Sun) assuming you are pointed in the right direction.

The best shot we have at actually reaching another star system with current (or close to current) technology is something like Breakthrough Starshot. A tiny tiny satellite with a huge solar sail being continually propelled by a system of 100 GW lasers on the ground. The early concepts estimate that it could get to Proxima Centauri in ~30 years. But we've still got a lot of technical obstacles to overcome for this one.

Ask HW: What open source projects have difficult performance constraints
Hi,

I've been really enjoying doing optimization work. I work as a game engine programming in the industry and I'd like to contribute to some open source project where my contributions focus on performance. Is there any interesting open source projects that have very difficult performance constraints.

Thanks!
When I read about its performance, I had the same thoughts, however, I was surprised to read this in the Github project readme:

> TruffleRuby might not be fast yet on Rails applications and large programs. Notably, large programs currently take a long time to warmup on TruffleRuby and this is something the TruffleRuby team is currently working on. Large programs often involve more performance-critical code so there is a higher chance of hitting an area of TruffleRuby which has not been optimized yet.

I guess that they have a high-performing JIT, that is optimized for small but not large programs yet. I'm curious though, what, technically, makes such difference.
Well they wouldn’t need to do that, because you’re already pointing them at your IP, right?

Cloudflare are providing the service they say they are, it’s the customer’s fault if they don’t understand basic best practice.
So you would rather your neighbors be poor?

CIA's Studies in Intelligence Vol. 66, No. 1, March 2022 [pdf]
I dunno. My main point was that I haven't stumbled across many interesting NFTs, but I wanted to at least leave the possibility that the medium just hasn't matured enough to create art that us non-NFT-hobbyist people would find interesting.

I'm not sure how one would curate an NFT museum, I imagine you'd want to display the jpeg and then select for pieces that play with the uniqueness guarantee somehow.

I haven't the foggiest clue how that would work, it if it is even possible, or what it would look like. But people have only been doing them for a couple years. If we made a museum that sampled the NFT population as selectively as an art museum samples the overall art population, that NFT museum would have approximately zero entries, right?
That headline doesn't seem to quite fit the facts.

Seems like it's being left up to the company how they count them?

> For numerical gender disclosures, the FCA said companies can report either on the basis of sex or gender identity.

> It will review the rules within three years to assess whether the nature and level of targets “remain appropriate and sufficiently ambitious”.

> In terms of its own diversity targets, the FCA said it reports on a “self-identification basis” and will continue to do so going forwards.

Possibly that's talking about two different things in the same muddled article but if I had to pick malice or incompetence, for the Telegraph, I'd lean towards both.
> If you compare by a boolean variable, for example, partition data by existence of something, it’s very tempting to write std::sort call.

> We saw a pattern of sort+resize a lot.

These seem like good opportunities for clang-tidy checks.
Another major difference is that Svenson intentionally omitted faces, so determining identity is very difficult. Leaking emails to Gawker for users' AT&T accounts is partially identifying its users, so it could even be considered a hostile action (against either AT&T, its customers, or both).
"As opposed to load-linked/store-conditional, which is a different way to express the same basic idea? Or is he claiming that other processors didn't support any form of atomic instructions, which definitely isn't true?"

It refers specifically to things like fetch_and_add. Supported by risc-v and i64.
I'm disappointed this article doesn't contain a single quote from either the researchers or Oxitec (nor does the earlier article it links to).

The experiment has been underway since April 2021 in the Florida Keys ... over the course of seven months, and has now almost completed monitoring the release sites.

An obvious question would be "What are you monitoring?" and to explain why 7 months is sufficient to detect any ecological changes.

Not for or against the research, and I understand it's a magazine article not a newspaper story, but this seems like more of a PR piece than real reporting.
If you examine the modification more closely, it is just finding the list that would exhibit worst case performance - once created, that list would always exhibit the worst case as a constant list.

Once you have the resulting list, the indices are sorted, then assigning each num_solid value to that index would result in the list being constant, and then could be sorted to give such worst case behavior.

I wish the article was more clear on this.
Average assault and murder rates are massively inflated by a handful of exceptional cities. St. Louis (usually highest murder rate in the US or close to it) is pushing 70 murders per 100k. That is roughly double the rate of Cleveland (rank 5). Cleveland has a murder rate over 10 times higher than a city of around ~40k people that I live fairly close to. However, another city (population ~45k) that is about a 20 minute drive away from the one I'm near has a murder rate over 15 times higher than the city I live near.

Crime is experienced incredibly unevenly in the US. I won't say much more past that because it's where the politics starts to kick in and I don't think that will add anything to the conversation.
I'm a security engineer and I still almost got scammed
Even if some of the data is wrong in the video (according to supporters on the Safemoon subreddit), it's pretty obvious that SFM is a scam.
> if we can also normalize accepting that emotional pain and injury is no less serious than physical injury

they are not.

they are in fact worse.

I suffered so many physical injuries when I was a kid that I stopped counting them, none of them traumatized me.

They are now good stories to tell.

On the other hand emotional pain was so unbearable that there are people I still don't talk to 35 years later, because I don't want to remember.

You know why they are so terrible?

Because people wanted to "share the pain" and made a big fuss about it and forced me to "confront my feelings" "live the pain" and all that hippie stuff, that only made it worse and gave me the idea that suffering was something you couldn't escape from.

Now that I am a full grown up adult, I'm still sometimes scared by having the feeling of feeling something.

If people could just normalize the fact that everything pass and everything goes away with time (except of course real traumas, like war or being abused) kids would realize that there'll be a day when they will stand up for themselves and the high school bully did a really bad job at ruining your life, there are so many worse things in life, that you kinda admire how stupid they were.

> than some people can't just "walk off" a broken ankle.

actually, most of the times you can walk off a broken ankle.

Typically, a minor ankle fracture won't prevent you from walking.

I think it's slightly different actually - I think it's a place where founders and VCs can promote their portfolio. I've been asked to upvote many posts on PH from friends and acquaintances and 0% of them have been pre-funding. I'm sure that there is some VC sourcing going on for sure, but my sense is that it's an early stage marketing channel first and foremost.

In the case of my alum, I think I can tell you: they spent it on housing and amenities to attract more students (quantity, not quality). I watched it happen while I attended. A university operates under the same principles as any other business in this case. Administrators are not innocent here, but they do have to live within the system and work with the incentives they are provided. Loans are made available to students and parents to shop around. This is a big part of what has created the upward pressure on tuition. We’ve revitalized a lot of state school campuses while letting their academics rot. Parents and students see fancy common areas, gyms, cafeterias and living spaces when they visit campuses then use that to decide where to go unless they’re very focused on the education, which they’re likely not because most very focused students require less financial help. If that money had been given to the administrators we are often so quick to villify, this picture may be a very different one.
To the commenter above this, is the M1 able to handle a 4k resolution on well its own ground?
I have the M1 Pro with (8 + 2) cores. But seeing as the cores are identical I suspect with the base models with (4 + 4) cores you'd see very similar performance except you'd be looking at 5x rather than 10x on multicore workloads.
Yep. I used to be park of a park advisory council in Chicago. At one meeting, police were there to field questions about park safety. One of the attendees mentioned their concern for the times they saw "unsupervised 10-year-olds" playing in the neighborhood park. The cop encouraged the person to call 911 when they observed that happening!

In Chicago, it's pretty much illegal to be a kid without an adult present in most places. In the Southern California suburb I live in now, it's better in that respect. Unfortunately, it's not walkable or bikeable outside of the housing development.
Amazing how much you can accomplish in a single rack. If you'd have asked me before reading this I'd have fully expected a far bigger and more complicated setup.
Its an interesting piece of legislation to see, and strongly implies former senator Joe Bidens initial student debt legislation was beginning to have seriously negative repercussions at the federal level for employee retention and hiring not even 5 years into its inception.

Back in 2005 Biden supported and stumped for a bill that stripped students of bankruptcy protections and led the country into a 1.7 trillion dollar student debt crisis. Watching President Joe Biden offer token debt forgiveness in 2022 is a little bit infuriating to watch as he could easily have spent the last seventeen years working to reform his mistake. If i had to weigh in on the sudden rise of student debt forgiveness under the current administration id say its political. inflation, gas prices, housing shortages, and supply chain issues have made it all the more practical to take action now and shore up the old midterm voter appeal.
A Tribute to Seymour Cray - https://www.cgl.ucsf.edu/home/tef/cray/tribute.html

> Off the job, Seymour found many ways to distract himself from his professional challenges. He enjoyed skiing, sailing, wind surfing, tennis, hiking and other sports. Some of his distractions were unique and formed the basis of many stories, most of them true but perhaps distorted with time. He used these distractions to clear his mind for his work challenges. One favorite pastime he had was digging tunnels for the sheer joy of digging tunnels.

> Seymour loved challenges, and digging tunnels was just another challenge for him. Even as a child, Seymour was a problem solver. His sister tells the story about when Seymour was a young boy, he rigged a Morse Code connection between his bedroom and his sister's so that they could communicate after lights out. His father became aware of the late night clicking and told Seymour to shut down the system because it was bothering the rest of the household. Seymour's solution was to convert the clickers to lights and to continue to communicate with his sister.
> It fails to explain why neighborhoods that kids played freely in decades ago now keep their kids inside. I'm talking about suburban neighborhoods in modest towns that haven't seen population growth or urban development.

This is a good point, although I would like to see some data to know whether this is actually common, or whether it's merely a common perception. If you actually control for things like population density, demographics (most notably age distribution), traffic, road design, city design (distance to schools, playgrounds, etc.) do you see a clear pattern of reduction in the number of children playing freely outside?

I have no doubt that there are plenty of places where this has happened, but I also have anecdotes of places where this hasn't happened (at least in the area I grew up in since I was a kid in the 90s).
It's actually funny: the only info given to the women/men were pics. What else are you going to evaluate on with pics ? Wit ? Smell ? Kindness ?

Alternative could also be “government obfuscates prices for education and certain types of labor by offering nebulous benefit, the cost of which can be subject to much manipulation for purposes of presenting it as a low cost benefit”.

It would be straight forward to simply pay for higher education expenses directly, with much less bureaucracy and more transparent pricing, allowing for better allocation of society’s resources. But, as always, that would reduce the avenues for corruption, and so the politically viable option is the circuitous option.
as a trader I know defi is not more cost-effective. the fact that most of the alpha in defi is in arbitrage tells the whole story.

the range of possible exploits on centralized equities and futures exchanges is very limited. HFT works, and works well, to drive down costs for retail and institutional traders.

there is no happy path in defi which results in narrower spreads, and less risk of block re-orgs, or other exploits which either drive up costs or massively undermine the entire ecosystem.

once again, trust is a lower energy state which pays for itself. this trustless, decentralized mania only serves a tiny subset of early entrants, arbitrageurs, and VCs. it does not result in a better market system by any way of measuring that I can see.

Why does every European who wants to be successful move to the US? Why is almost every innovative and successful company from the US?

Providing free stuff to layabouts isn't a recipe for success. These "investments" will never pay off. The way to incentivize economic success is via competition.

Unfortunately the US is already far down the path of handouts and participation trophies, and has nurtured an utterly entitled generation who think everything should be handed to them.

Not only that, but they worked in government or non-profit (under a specific definition of both of these) long-term while making 120 non delinquent loan payments (10 years) only if the loan is a specific type of loan. These people are by government definition not a 'mess.'

Having the touchbar and the function keys would have been nice (e.g. if they had kept the function keys half-height, possibly with the exception of the escape and touchid keys).

However since apple decided that only "either" was an option, I'm much happier with having the function keys back.
>It used to be that if you wanted to watch a movie, you opened up Netflix.

I don't recall Netflix ever having a good movie catalog for streaming. It's TV catalog used to be amazing though, but that was because they were essentially the only person paying for rerun rights to shows that weren't popular enough for syndication.
