There are tons of examples of physics engines running on the GPU. Contact resolution (particularly between simple shapes) is an embarassingly parallel problem. I don't think it would be impossible to handle millions of collisions per frame on a modern GPU, maybe even CPU. Also, what counted as a high-end server a decade ago probably is much more affordable with today's technology. You can also probably design a scripting system/set of game rules which allow unobserved NPCs/objects to sleep when no player is around them.

User content can probably be limited as well so that people don't upload overly complex/poorly performing 3d assets.

I'm not saying that this isn't a tall order, but I think it's far more manageable by a sufficiently determined and talented team than it was decades ago.
I think OP agrees with you and is trying to say that the tendency of us to prefer institutions over families can lead to this.

For example, I know when I was a kid the school teachers and people were constantly worried about me and my family since we're immigrants from a part of the world they thought of as "backwards". We did not have liberal social views, and my parents opted me out of sex ed, LGBT events, etc. One time I mentioned a comic strip (Calvin & Hobbes) in which the kid dreamed of flying an F-14 with a team of T-Rex pilots to blow up his school because he really didn't want to attend and I was called in for some government program to prevent terrorism and they asked me all sorts of questions about how violent my parents are and did I believe in violence as a tool to solve problems, etc.

Sometimes our tendency is to "civilize" children when we think parents aren't doing that. What OP and you are trying to say is that what parents and family offer (accountability, care for the child, etc.) is usually better than any "values" an institution can impart onto a child. Institutions can often be cold and cruel in a way few parents ever are, and so the tendency to lean on institutions with regards to molding children is one we should avoid unless absolutely necessary.
> Evidence of submission is displayed by the employee’s going through years depriving himself of his personal freedom for nine hours every day, his ritualistic and punctual arrival at an office, his denying himself his own schedule, and his not having beaten up anyone on the way back home after a bad day. He is an obedient, housebroken dog.

And in exchange I get to not really care about complicated things I do not enjoy other than whether it indicates I need to go find an owner with more dog food, I practically get to use many of those hours at work as I please, and at least as a professional, I can carve out hours as required for other things.
If they alter the airflow direction sufficiently so that it comes from behind such barriers probably do have some benefit. There was a fluid dynamics study done of a café where some people were infected. When they modelled the airflow they found that those infected had been facing into the airflow. People facing downstream were not infected. I don't have the url to hand, if I find it I'll add another comment.

> Currently the US use foster homes rather than orphanages, but is it a better system, just different, or worse simply a more efficient way to hide problems

I can say anecdotally that being in a foster home was a much better experience than being in group homes. I am sure experiences vary, but I went from feeling like I was a prisioner in group homes to a family in a foster home.
I guess it is conceivable that you could take 1000 dirty input files and their cleaned output and use this as a training set for a ML-power data cleaning system. But:

With Melbourne having been in lock down last year for more than 3 months in a single stretch, everyone who physically could work from home were forced to... and now we're all used to it. As companies have slowly opened offices back up in the past few months, and some companies forcing employees back into the office, I think that's given a lot of managers perspective in term of work from home... in that, if you don't continue the option of work from home, you're going to lose staff.

My brother-in-law recently spoke to a recruiter who had two jobs advertised. Both jobs had the same job description, and the only difference was that one was work from the office while the other was work from home (with a $20k pay reduction). Over 60 people applied for the work from home role while a single applicant applied to the work from the office role. Let me repeat - people opted for a $20k drop in pay so they could work from home.

It's good that Silicon Valley companies are letting people repatriate whilst not losing staff... I've always thought that only focusing on the small pool of people in your local area for perspective employees was a hiring local maximum.
I would support all that.

When starting out, take that weekend course your local college offers - and try all the bikes in a controlled safe environment. I was shocked how much I didn't want a sports bike - the posture and low speed maneuverability were horrid. I also didn't like cruisers personally, didn't feel in control leaning back. I turned into a lifelong standard posture guy - whether city bike or adventure or dirt/supermoto... But point is, find out what feels right for you, rather than get a 750cc superbike as your first ride based on specs or review or what you think may work well.

I had fun going full throttle redline on... My cbr125, back in the day:D. More so than on some twitchy overpowered bike where I feared touching the throttle.
In the aggregate, drug usage is not enough of a problem for distributing money to not be of massive benefit to the poor. Nor is it enough of a problem to financially or morally justify the various schemes people have come up with to cut off drug addicts financially or to discourage drug usage by paying them in scrip. Giving money to everybody blindly with the awareness that statistically some will waste their money is better than any alternative.
They have their place in hell next to the quad bike owners,who think it's ok to use them in urban areas. None of them are cool, only complete douches.

My understanding of the best practices is that shelling into prod is a breakglass only. Developers need approval to get escalated permissions to shell into prod in the first place. Further, containers shouldn’t run as root (security) so I don’t know how you would install software anyway. Logs and metrics should similarly be queryable via some central log explorer service like CloudWatch, Splunk, Prometheus, or even kubectl+grep. You shouldn’t have to manually page through GBs of logs.

Our images are often pretty stripped down (coreutils at most, often just a Go binary and some certs), so there aren’t many debugging tools available.

This might make our time to resolution slightly higher, but it keeps our incident count quite a lot lower because we very rarely need to break glass in the first place (this means you have to establish norms for logging, instrumentation, and tests).
I’ll give you three guesses how many shits governments give about pot heads buying crappy pot.
Can attest to that. C++ is also OK. You still have to write the 'binding' but the compiler can generate a good part for you. Then you can 'hide' all the C-like things (like 'a pointer is an address', 'an enumerated type is an integer', 'you have to call our free() when you're done'...) behind opaque types, controlled types, etc.

As a simple example you can lookup what the compiler generates as a low-level binding [0] that is wrapped in a higher level API [1].

BTW you can also bind Ada to Java (although support is a bit limited I know places where it's in prod). Don't remember if it's a commercial product or oss.

And for the python people, my company financed a first version of ada-py-bind, inspired by the great pybind11. Still a lot of code to write (or generate) but it works fine.

Thanks onox for those two links!

As far as I can tell he’s doing this with money from Apple, so, swing and a miss there.
Quite good by local standards, but a far cry from Silicon Valley levels. Taxation is a killer as well, and the cost of housing in Sydney is not far off SV levels.

If you by "ambitious" you mean ladder-climbing/director/co-founder by 40, SV definitely has a lot more options. But if you just want interesting work, it's not too hard to find.
It seems like the Catholic Church is often (always?) somehow involved in these systemic child abuse/mass grave stories and it’s mind-boggling to me that we continue to allow an organization with that kind of track record to take responsibility for caring for and placing at-risk children.

One of my favorite writers. Highly recommend to read also his less famous works like "das Schloss", "Amerika", or "in der Strafkolonie". If you dig such books, give also Robert Walser and Bruno Schulz a try!
> Bluntly put, when an institution is given power over children, more than that of a family, and the auditing is lax, you're gonna get maltreatment, and from there unmarked graves.

Families are not particularly safe. Systems that pulled children from their family for placement in a "correct" family created similar horror stories and the natural families of many are also horror stories.

Air crashes are more notable than auto-crashes despite being less likely per passenger. Similarly, even if institutions fail at 1/10th the rate of placement in families, notable news will still paint us the opposite picture.
When I moved to Thailand, I got into contact with a Dutch national of Jewish decent. We occasionally meet over coffee and have a little chat.

When he was young, after WW2, he lived in several foster homes spread over Europe and managed by nuns. He told me he often had to sexually pleasure the nuns in order to get some extra food. His parents were not able to care for him in this period, but eventually he got back with his parents.

He told me he doesn't look back in anger over that time period though. As far as he knew it was the same in most other foster homes.
Troy Hunt has blogged a few times about the legitimacy of his service, and it's clearly been a carefully walked path to where it is today.

I think ultimately it comes down to the fact that he's not redistributing the lists of emails, and he doesn't retain pairs of (email + password hash). He designed the site to provide two useful queries ("what breaches included my email" and "has this password been seen in any breaches you processed"), which strike a responsible balance between disclosure and privacy.

Moreover, he has written about his intentions and acted with a fair deal of transparency, which is a strong contrast to some of the shady behavior you'll see from people dancing in the gray areas of the law.

That was probably a stepping stone to partnering with other organizations, which has snowballed into having the cooperation of the FBI, as well as the endorsement of multiple countries' governments.

It's worth pointing out that the abstract of the Nature article appears to suggest that the pre-Columbian evidence is for a different variant of TB: "Here we present three 1,000-year-old mycobacterial genomes from Peruvian human skeletons, revealing that a member of the M. tuberculosis complex caused human disease before contact. The ancient strains are distinct from known human-adapted forms and are most closely related to those adapted to seals and sea lions."

This is completely speculative, but if post-contact TB was a different strain imported from Europe, that may explain why it took such a toll on Indigenous peoples.
Ok, but companies do select based on Leetcode performance, in practice. It's the largest portion of the interview. It's useful as a filter, but it's treated as a benchmark. As evidenced by:

> Personally I did double my income by going through this
process and I've seen many others do as well.

That's insane. That's a broken market. If that's happening, it's not a reliable signal.

Ultimately, if the market is rational then your actual ability will matter more than anything else. The only time that isn't the case is if the market is irrational. You can argue the market is currently irrational (although I would say that's not quite what's going on), but placing a long-term bet on it staying that way... Bad idea, IMO.

But I think the actual explanation for why high-tier (read: large) companies use Leetcode is a combination of the fact that they're monopolies, so they aren't punished for bad selection criteria (see Google's use of lateral thinking puzzles for years before admitting they were completely useless for predicting job performance), and that they need a replicable interview procedure that can be applied consistently by a workforce that fundamentally isn't very good at interviewing, thinks they are, and doesn't care if they get it wrong. It's the Big Mac of interviewing methods.
The article conflates school and life. While school occupies a lot of waking hours it is not synonymous with it.
Kafka is one that I thought for some reason I knew enough about his works via cultural references to know about Kafka without actually having read any of him.

The pandemic changed that; he's so much better than his reputation-based assumptions. If you've been putting it off, jump in! His works made me feel things I have only ever rarely or have never felt before. It's uncanny.
They should partner with local embassies who would get free publicity for helping show america how to have a free(er) market.

I think you're wrong. Running a thing in a slightly virtualized environment doesn't suddenly change the nature of the thing.

I'd say embedded operating systems are more of exact opposites. A unikernel runs a single applications in a fully-capable system modern computer. An embedded OS does the opposite, being able to run multiple applications on a system that wouldn't be thought of as a "computer" (in the PC sense, not a literal one).
An alternative to capping is to avoid adding anything to the integral term in situations where the actuator is already at 0% or 100% of the possible range.

Perfectly fine is understating it. You get paid more if you do it.
If someone is referring to that rating system they should use its definitions. Below level 1 is functionally illiterate. Levels 1 and 2 are not functionally illiterate, they are low literacy.
$20k/year gross = $250-ish/wk after tax. Given Sydney housing prices, you may still be better off taking the lower package and living somewhere that's not Sydney.

I wonder if it would be possible to devise a different/better version of LinkedIn?

Could you create a social media platform that takes the positive aspects of LinkedIn (large network of users that are, at least ostensibly, targeting ambition, hard work, and self-improvement) but that leaves behind the accompanying parade of inauthenticity, brand names, buzzwords, tropes, and recycled posts?

I wonder what this would look like? Would it be possible?

One idea… a social media platform where people promote, share, and encourage meaningful projects :)

Thoughts?

I can’t compare with the Garmin, but the Pebble experience was subpar. I stopped wearing mine after a few weeks and gifted them to my mother after a while (she loved the pebbles but had constant issues with connectivity on Android). On the other hand, I expected to return my Apple Watch (it was an impulse buy due to a discount). But it really grew on me. It’s actually a “it just works” product (which I can’t say of a lot of Apple products these days). A friend of mine has a Garmin, but afaik he can’t do much with notifications. On the other hand I have quick replies, voice to text or depending on the app quick actions. That’s just not in the same ballpark. Do I need it? No. But it’s really convenient once you got used to it. I don’t know how many times I set the timer with Siri because my hands were full or dirty. If a second SIM card wasn’t so pricey in Germany I would probably get one and leave my mobile at home most of the time.

I've actually read their terms of service and rechecked out of curiosity right now — I fail to find anything along the lines of what you mention. In addition, that doesn't make technical sense, how would they store credentials for 2FA?
And to be clear they also support C on GCC, so our gcc bugs go there too. Also very very happy with AdaCore's tech support. Response within the day, help and patience in reproducing problems, and almost always with a quick workaround. Often citing the reference manual. You also often have an expert jumping in to help, or to answer a question, or to implement some optimization :-)

I still have fond memories of (the sadly late) Robert Dewar answering a ticket of mine 'this is so slow, whyyyyyyy?' with a 'we have implemented a change that should improve the performance of your code' so fast I hadn't had the time to go talk to our local Ada guy for an alternative idea.

They also have world experts in formal methods like Yannick Moy and Claire Dross who will help you prove you jump-start a Spark project and are pushing the state of the art every year (proof of floating point code, pointer/ownership...).

Money well spent.

And to be clear: not from AdaCore, just a customer.

Yes for London the WW2 period sure did change the landscape in many ways and I recall being supprised that it wasn't until 2015 that London's population had finally caught up with level it had in 1939. That alone really did highlight how some things can be impacting far wider than we appreciate.
My bar for adding value to life might be lower than GP's but I do get value-adding posts in my feed. It's basically boring updates from people but made less boring because I know these people.

I was thinking more like by late 20s if they start young, but basically yes.

I personally didn't enter the industry until my 30s and in many ways I think I'm fortunate that my first job was at a startup in Beijing and the next 3 years were all in SF. Back when I was there, it was an amazing place to learn, albeit very expensive and without a commensurate quality of life outside of work.
By that logic, nobody should ever attempt to ever disrupt anything- the existing interests could use it as an excuse to do bad things.
