My personal advice for anyone wishing to master dynamic programming: learn about recurrence relations first. When I first started learning dynamic programming I didn't know about recurrence relations. It was very frustrating to somehow "sense" that a problem involves dynamic programming but can't describe it properly; that basically means I'm unable to apply dynamic programming principles to any new problems other than a few studied and memorized examples like LCS.

Later on after I learned recurrence relations I relearned dynamic programming and it's a breeze. To be sure you just need to structure your mind to think about these problems in terms of recurrence relations. You don't need to go as deep as I did learning about generating functions (though they are interesting and useful on their own).

Also I don't believe in learning it in 30 minutes. You can get an overview in 30 minutes, much like you can finish a chapter or two in a calculus textbook in 30 minutes. But you won't really learn it until you do the exercises and practice problems.

While being poor may not lead to an unhappy life, having high income volatility will.

And in the US, low income and high income volatility go hand in hand. You can have your hours reduced or shifted at any time, your industry can get outsourced or automated, you may be deemed to be too old or expensive.

No one is happy with volatility, and no one today should expect to go to work and punch in and out for 30 years, especially if you’re on the lower end of the pay scale. You should be looking out for better opportunities all the time, lest your cash flow suddenly stops.

Hey HN, author here. If you have an questions or feedback I'd love to chat. I'm also going to try post a new blog every week. Some upcoming topics will be about the technology behind the app. It's got some cool stuff in it which I'm keen to share.
This is probably a reference to Youtube's reaction of the COPPA lawsuit.

Basically, Youtube will hold you responsible if you upload something to Youtube without properly tagging if the content is rated for children or not.

However, they also said that anything that may be related to children (toys, kids' movies, etc.) should be tagged for children.

If you tag something as rated for children and it's not, Youtube will punish you. However, if you talk about a new Frozen movie or review Lego (toys) and use swears, that's children's content with adult language, and therefore punishable.

The FTC has published rules about this[0] but has in the past stated it intended to go after Youtubers who broke the rules.

These toggles also have an impact on how your videos are monetized and functionality [1].

So, an adult reviewing lego and calling it "fucking amazing" might be right in the middle between "FTC lawsuit" and "account banned by Youtube".

Of course this is all further complicated by the fact that other countries will have different legislation. A video marked as viewable for children by the Youtube rules may get you into legal trouble in another country.

I'm not necessarily against COPPA but the way the lawsuit was settled caused quite a stir on Youtube and threatened the income of quite a few people, which was made worse by the terrible UI Google has built into Youtube (you couldn't mark a set of videos as "for children", you had to go through each one, and every day a video was up was a day the FTC could send lawyers after you). If Google had handled this better by providing the necessary tools and clear information, this wouldn't have been a big issue at all.

Through the political pressure that Elon is exerting, it should be clear to his employees that he thinks they have poor judgement if they choose to stay home. Why would you feel safe working there during or after this?

Also, if you are working in unsafe conditions right now and you aren't an essential employee -- you are a scab who is making negotiating national benefits harder which would otherwise help every working person more.

This is a classic prisoners dilemma and Elon is unfortunately one of the jailers.

I don't think the author actually has used AWS extensively or in recent times because almost the whole section on EKS is wrong or out of date.

That's often mentioned but there's a bit of a problem there. If you can get net power from fusing He3, then you can also get net power from the easier D-D reaction, and the waste product of D-D is....He3! Half directly, half as tritium which decays to He3 with a 12-year half-life.

Even though D-D emits neutrons, they're at an energy similar to fission neutrons, rather than the extremely energetic (and easiest) D-T reaction. It's almost certainly going to be cheaper to get your He3 from D-D fusion, and get energy in the bargain, rather than sifting through millions of tons of lunar dirt.

Fusion startup Helion, funded in part by YCombinator, is working on a hybrid D-D/D-He3 reactor, saying the combination will produce only 6% of its energy as neutron radiation, compared to 80% for D-T.

There are plenty of psychiatric disorders that are demonstrably structural in nature, such as schizophrenia (likely genetic, lifelong and incurable), but there are plenty of others that seem to be a disorder in the contents of your brain rather than its structure. An example is depression, where people seem to be able to think themselves into depression and think themselves out of it.

I'm pretty sure most JavaScript games use object pooling extensively. GC is definitely an issue if you want to hit 60fps. Even for non-games actually.

> The money is to be made telling stories about it vs doing it. Which is why I think the article is complete fiction.

It's funny, but it also just reads like bad fiction to me. The dialogue doesn't seem natural, and the writing doesn't sound so much like someone describing something they actually experienced as it does like someone mimicking a storytelling style they've seen elsewhere. Add on top of it that almost every aspect of it seems ripped directly from the first half of "21" (the Kevin Spacey movie about the MIT crew) and it just comes across as an amateurish attempt to borrow someone else's story. The fact that these techniques she claims they used just don't work anymore seals it for me.
I've been working from home for the past 10 years and I don't think I could go back to a regular office.

- I can work at my own natural pace whenever I want. Some days I work 4 hours. Some days I work 12 hours until 1-2 am.

- If I need to buy something I just do it. I can go to the supermarket at the best times.

- I can eat home made food and follow any schedule I wish. My SO also works at home and we're doing intermittent fasting 4/20. We start eating at 2pm and stop at 6pm.

- I loooove espresso. To give you an idea my espresso setup costs more than my work setup and I roast my own beans. No office could provide me with this.

- We have 2 large dogs and we just couldn't abandon them for 8-10 hours every day. I don't know how people do that.

- We can live wherever we want and we don't have to pay extra to live in a nice house. Gone are the days of living in apartments without garden.
If you want to know more about the server performance situation I recommend watching a video[0] about the subject from our lead gameplay programmer.

I'm getting very tired, and irritated so my responses are coming off as unreasonable now, so with a final hopeful breath let me say the following: I hear what you're saying.

Truly I understand that you think that it's super easy and we have so much money that it should be solved.

We don't have the money you think we do, we run on very thin margins, in both time and resources.

Others have mentioned that we should shift the burden of running servers to users, but that has many tradeoffs and doesn't work for many games- especially not on consoles. Especially not in the sheer numbers of users we have.

The issue is also understanding what 'security sensitive parts' are, because what is that? Everything is sensitive, movement, bullets, health, what you see, what you hear, what you can interact with, what loot you picked up, what gun you have equipped and how fast it's equipped, how fast you reload, how many bullets are in the clip.

If you were to stall a client so that the server verified you could do those things then your game is running 1 frame every 20 seconds. That's even if you had infinite performance on the server to make those calculations for the 24 players that can see each other.

It's a hard problem, one I genuinely invite you to solve for yourself, maybe the answer is to make much simpler games like CS:GO or Minecraft.

Or maybe the answer is simple and everyone I work with, both in my office and in the industry of AAA gaming, is malignantly incompetent like the commenters here keep suggesting.

Women are the majority of CS grads in Saudi Arabia, and you'll find that they are many women studying CS in third-world countries that typically are less "gender egalitarian" than Western countries.

In wealthy, western countries giving men and women the choice of what to study without having to think too much about where they'll end up in society, that's where you see the most gender imbalance.

I think willpower is an important factor, but not the only one. The bigger issue is viewing lack of willpower as a personal moral failing rather than something that can be fixed with practice and attention. I really buy into the fact that willpower is like a muscle that you can exercise and that there are real practical ways to improve it. I've seen huge increases in my own focus and working ability in the last five years - part of that due to a maturing prefrontal cortex but in large part also because I've taken concrete steps to improving it (and reducing procrastination).

That is not to say that all distractions are easily fixed or that everybody should have great focus and attention.
I'm not sure I agree that complexity is always conserved. When I design systems, I often find that there's intrinsic complexity that I can't seem to escape, but that my initial designs are often quite poor and also include incidental complexity. If I'm thoughtful, and I learn the domain well enough, I sometimes find I can remove that incidental complexity. Alan Perlis had a couple of epigrams that echo this, I think.

> 31. Simplicity does not precede complexity, but follows it.

> 58. Fools ignore complexity. Pragmatists suffer it. Some can avoid it. Geniuses remove it.

All that said, I've definitely seen cases where trying to insulate the user from the reality of what's happening behind the scenes often dramatically increases complexity. When it's done poorly, in increases complexity not only for the designer and programmer, but the user as well. One well-known example is the progress bar. After 30 years of lying to users about how long that file copy, download, or compile would take, many recent designs simply exclude it and include an animated spinner instead.
Case 1: CEO allows democratically elected county officials and their experts to make policy in accordance with public health

Case 2: CEO abuses authority by coming in to work which pressures his employees to work against the interests of public health and democratically elected leaders

Case 2 is clearly fascist and Case 1 is not.
A lot of people don't really do anything but churn and make sound and fury, signifying nothing.

There's much less cause for engaging in that behavior when everyone is working from home, so it becomes more apparent that they don't actually do anything productive.
The question was asking why some people are better at working at home than others. You seemed to answer the question "how awesome is working at home?". ;-)
What exactly don’t you buy?

Isn’t the point of the article that if one company provides a good enough experience for many things that doing one of those things better may be a good business opportunity? It may be particularly attractive to the subset of people who rely on that one thing.

The point doesn’t seem to be that you need more integration tools. It’s that if one integration is very important to you, you might want a dedicated tool that provides better experience and value.
I have a 2070 non super. Minecraft RTX was acceptable. You can't get competitive FPS gamer acceptable framerates but you can get RPG/minecraft acceptable framerates (40ish) depending on how spoiled you are by 144+ fps feels.

But yeah generally I agree, a game that is already doing AAA amounts of gemeometry and shading, that uses RTX to good effect, is going to need 2080ti in SLI to be still a bit slow.

> I have to work the same times anyway, or else I will just look like I don’t work.

Especially when working from home, doesn't one have to judge performance by the work output rather than physical presence? I understand that this ideal is not the reality everywhere, especially in the office if people don't know you started at 7am that they they'll look weird if you leave at 15h instead of 17h, but from home you can slack off anyway so you really have to look at the output and not presence. If not done already, you might want to look at tracking work time to make everyone feel confident that the others are doing their part, and bosses should notice when time worked does not match output.
My argument is that Elon has sufficient power that he wields against the interests of his employees that he himself is fascist. He is trying to override the policy of democratically elected leadership of Alameda County.

> "Free speech means you can't be prosecuted for speech. It doesn't mean people can't hate you."

Would you have said that to people in the civil rights movement or the labor movement? They were hated and mistreated by many as well and yet your words would have justified that.

The sword always cuts both ways. Your viewpoint will hurt causes you believe in just as much as causes you oppose.
I read it as hyperbole that means "the bar for what's a good question to ask is really low."
It's also helpful as an interviewer to ask "What questions do you have?"

The meta point of the post is it's dumb to attach too much weight to cultural signifiers that are easy for people to imitate once they know about them.

The top voted comment on the post invents a new cultural signifier, and declares that candidates who fail it should be disqualified! It would be funny if it wasn't a pervasive interviewing practice.

I find the Korean call center paper pretty interesting [1]. In early March, this building had 97 infections: 89 on one half of one floor, 5 on the other half of the floor, and 3 on other floors. The two halves of the floor were separated by doors but shared the elevators, bathrooms, etc. It seems clear from this that almost all of the infections were from being in a shared space with someone infected. (There's a nice diagram of the infections [2].)

The other thing I got from the article is that South Korea is on a whole different level of testing than the US. When infection was detected, they tested everyone who was in the building or had visited: 1143 people tested with results in 12-24 hours. Everyone positive was isolated and everyone negative was quarantined and re-tested for 14 days. They also texted 16,628 people who had been near the building for more than 5 minutes (from cell data), telling them to avoid contact with others and get tested. This level of testing and tracing got South Korea (51 million people) to the point that it is now averaging just 10 new cases per day.

Yeah, I miss the days when nostalgia was more common.
That's been my experience. For decades, I was diagnosed with depression. Eventually, I was prescribed an SSRI. And that became a disaster, over the course of a few years.

But then I saw a psychiatrist who inquired about my use of psychoactive drugs. And based on my love of stimulants, he diagnosed me as having bipolar disorder, manifesting primarily as depression. And so he prescribed modafinil, with lamotrigine to reduce the risk of mania.

So I wonder if bipolar disorder is actually relatively common. I mean, I was self medicating primarily with caffeine, and for many years used nicotine to take the edge off. Maybe that's fundamentally why coffee, tea, etc are so popular.

The Easy Way to Obtain a Website's IP Address That Hides Behind CloudFlare
Some people are more motivated than others.

Just like some people are more intelligent than others, or more athletic than others... some are more self-motivated and can work through their own initiative rather than relying on external input (such as managers).

That's not a bad thing, either! We should encourage those self-motivated people to work however makes them the most productive members of our economy. That is incredibly crucial for the times that we live in.
>Not a psychiatrist, but I'm pretty skeptical

i don't understand why people do this - if you're not an expert why are you pontificating? if a psychiatrist decided to pronounce on OOP vs FP or raft vs paxos or whatever would you give absolutely any credence to their opinion? this is an article on nature about a nature paper for god's sake - i trust them over my own opinion on the matter let alone your opinion.

edit: lest we forget a psychiatrist is an MD plus a 4 year residency. that's a total of 8 years of domain specific education.

According to the National Space Society:

> It is now believed that a lunar mass driver several kilometers long, designed conservatively with present technology, should be able to deliver 600,000 tons a year to L-5, or more easily to L-2, at a cost of about $1 per pound, assuming only ten years of operation.

If SpaceX succeeds in dropping launch costs below $50/kg with Starship, this doesn't seem like it'd be all that expensive.
I first experienced this roughly a year ago when I was having a discussion with a colleague in China, and she happened to be at home because of the time zone difference. All of a sudden, a baby started screaming and all hell broke loose. She was so embarrassed, but we all just laughed it off and she realized that we weren't annoyed at all.

When we all went on lockdown recently, I noticed that at first people were careful to create a "proper" workspace that was not only silent but also photogenic for their camera. Naturally, a kid sees a closed door with the most interesting new thing in the house happening on the other side. The only proper recourse is to bang on the door.

Even within just a few weeks, things have relaxed considerably. Now, I rarely attend a meeting, even when there are higher-ups in attendance, where there are not kid noises in the background, folks going on "mute" to deal with a meltdown, even just letting the kids play in the same room. Going shopping during the work day, when the stores are less crowded, is completely normal now.

When all of this started, some folks said: "Finally this will normalize working from home." Maybe it will go even further, and normalize folks having a real life.
Because people are sick and tired of rich people bitching and moaning about everything that doesn't go exactly how they want it to, that are entitled to everything they deem, and the idea that, because they had success in one area, that they are successful in all areas and are infallible.

Yes, Elon Musk did all this, not the 48000 some employees at Tesla, not the chemical engineers, not the mechanical engineers, not the assembly line workers, not the software engineers. It was all Elon. I mean, come on, when does the absurdity end? Tesla will be fine without Elon, and probably better off as he becomes more unhinged.
