Oh NTP... I remember a series of extremely annoying incidents that were caused by time skew on hundreds of Linux VMs in our data center. Our setup was typical of a startup - built to be good enough at first, and fall apart at scale.

Every VM ran CentOS, and every one of them hit the default CentOS ntp servers. These are run by volunteers. The pool is generally good quality but using it the way we did was extremely stupid.

Every few weeks we'd have one of these "events" where hundreds of VMs in a data center would skew, causing havok with authentication, replication, clustering. We also had an alert that would notify the machine owner if drift exceeded some value. If that happened in the middle of the night, the oncall from every single team would get woken. And if they simply "acked" the alert and go back to sleep, the drift would continue, and by morning their service would almost certainly be suffering.

Whatever about diagnosing the cause, I started by writing a script that executed a time fix against a chosen internal server, just to resolve the immediate issue. I also converted the spam alert into one that Sensu (the monitoring/alerting system we used) would aggregate into a single alert to the fleet ops team. In other words, if >2% of machines was skewed by more than a few seconds, warn us. At >4%, go critical. (Only critical alerts would alert oncall outside sociable hours).

Long story short, we switched to chrony, because unlike ntpd we could convince it to "just fix the damn time", because ntpd would refuse to correct the time if the jump was too big, and would just drift off forever until manually fixed. (No amount of config hacking and reading 'man ntpd' got around this). We also chose two bare-metal servers in each data center to work as internal NTP servers, reducing the possibility of DOSing these volunteer NTP servers and getting our IP range blacklisted or fed dud data. Problem solved right there, and we also ended up with better monitoring of our time skew across our fleet.

It's about future profitability, though. That's speculative, of course, but that's why the growth rate matters.
White Americans just after the second world war controlled a huge fraction of the world's wealth. It's incredibly easy to raise your family in relative comfort when you're part of the only industrialized society on Earth that hasn't been reduced to rubble, the ones being rebuilt owe you billions upon billions of dollars, and you have a reliable underclass of other races to do the most unpleasant bits of labor for you.
> Your end of life care is entirely dependent on other people having and raising functional children.

Presumably OP is in US and is not planning to have any kind of state pension or socialized healthcare when they are old?
Just in case someone gets the wrong idea, doing "hello world" first is a good habit for everyone when starting to use a new device or a new lab setup, not just beginners.

It's to make sure that the environment is set up right. Is the device getting flashed? Does it start up at all? If you make a change (blink at a different rate), do you see your change?
I'm impressed by the idea that it's even possible to stop people in general from having kids. In 1974 there were 4 billion people, and we were worried about overpopulation, with scare stories in the media on the theme of "standing room only". Now we are 8 billion, and worrying about low birth rates, even in China (see the "lying flat" trend). So, get back to me when we're down to 4 billion again and I'll consider supporting financial incentives to support future human life, but right now I don't see an existential threat from low birth rates. I do however think that it's really cool that people have the capacity to refrain from having kids when they know that it's a bad idea in their specific circumstances. I like this because it shows the malthusian overpopulation doom-mongers to be wrong, and they were getting annoying.
Individuals certainly aren't taxed on their net profit, so I don't see how that could be "fundamental to the whole premise". If the tax code has effects that are noxious to the public, it's a public matter to revise the tax code.
> Photos really don't belong in hiring in the US.

Sounds like someone needs to reread Don Burleson's professional dress code tips: https://www.dba-oracle.com/dress_code.htm

Presenting a polished, professional appearance makes a real difference to employers. They can and will legally fire you (or choose not to hire you) for failure to do so.
In general I completely agree that updating infrastructure to create dedicated spaces for non-car modes is the only way forward.

But given how politically difficult it is to change--and especially to take away--existing infrastructure, and how much easier politically it is to introduce new tech, I hold out a smidgen of hope that driverless cars might help us inch in the right direction. Because they'll be managed by companies rather than individuals, they almost certainly will be required to adhere strictly to speed limits and other traffic laws, can be programmed to give bikers and pedestrians a wide berth, and won't (I hope dearly) get road rage. With luck and a sufficient volume of autonomous cars, this could help more people be comfortable riding with cars until we can get enough political will to build some decent infrastructure for non-car-users. And at this point I'll take what I can get to keep the ball rolling (and hopefully accelerating a bit) towards a friendlier future.
possibly also seen as a 'safe' prank because there were no humans to harm in it?
It will take a bit more engineering than some optimistic sign-flipping to bring it down to $50 retail (~$10 BOM).

> In my case, the BOM was close to €2500, so be prepared for that.

EDIT: someone pointed out that there are actually some designs available on AliExpress, e.g. https://a.aliexpress.com/_EzMRNIv €250 for one axis (edge) and €500 for a 3-axis (single point).

Because the individuals responsible are young and impulsive, this is not lawlessness.
That was also concluded by Hans Rosling: the higher the education of people, the fewer kids they have. Best way to address overpopulation is by increasing education worldwide. https://www.teesche.com/bookshelf/hans_rosling_factfulness
Life generated from DNA in a vacuum would probably be pretty boring. The entirety of life requires some surroundings to interact with, and as it stands there is but one of those, and singular things don't compress well.

Also, have a look at the Mandelbrot set again. There's quite a lot of information in, arguably, a very modest process.

And finally, to suggest that these 256 bytes are less impressive than they are, consider what hardware and software is needed to support it. These 256 bytes would not lead to the same illusion on a C64.

This is such a weird thing to use when on other hand you have developers slinging code for basically pennies and then silicon valley guys making almost seven figures.

There really is no good way to estimate any of this
One perspective I find interesting is how fast Microsoft grew in the desktop pc area:

https://twitter.com/marekgibney/status/1753116011681968552

Back then, for over 10 years, it grew at a pace not seen since then.

If Nadella grows Microsoft into the AI area as fast as Gates did in the Desktop area, it would become a 100 trillion dollar company within the next ten years.

Is AI a step forward for productivity as big as desktop computers were back then? I think it might be. Not sure what percentage of people became more productive via PCs. And how much more productive they became. But with AI, it seems everyone will benefit from it. And become twice as productive or so within the next 20 years.

Programming without an LLM at hand would already feel very clumsy to me these days.
Then it's still incorrect because that wouldn't break the blockade, which would be enforced with radars and anti-ship missiles. Also, it would not be smart for the US to try and mine PRC ports: how many bombers and ships would they lose getting that close to the coast? I actually don't think it's achievable, but even if it was the cost in lost lives and materiel would be ruinous. All to achieve "stopping the PRC from shipborne trading off its seaboard", except that the PLA has a very large number of demining vessels, and if the USN hasn't sacrificed all their ships into the missile meat grinder to try and get some mines placed off the Chinese coast they can interdict shipping at other locations like the Straits of Malacca, the Red Sea bottleneck, etc. Chinese civilian shipping can be stopped in other ways that don't involve sending the US Navy on a suicide mission.
I know that self driving cars are eyerolling to hear about, but highway self-driving with convergent infrastructure (not the drive-me-thru-Taco-Bell kind) is going to come to trucking, for the basic reason that you can drive the trucks overnight at a minimum.

Smaller planes seem mostly designed for shorter flights, but if I can get a better-than-sober-me stats on highways, and I can sleep in a car while it drives me to another city, why would I fly?

- take a lot more stuff with you

- for families it will be insanely cheaper

- if an EV, it will be lower carbon

- I will have a car for last mile/city driving when I get there

- much better seats

I honestly think the 20 year prognosis for <800 mile flights is going to be really bad. 800 miles flying is 2 hours + taxiing + waiting in line + transport to airport + giving yourself enough buffer + land/get luggage + ground transport. That is probably 5-6 hours in many situations.

So a 10-11 hour drive where you don't have to pay attention and can sleep overnight would be my primary choice if I could do it now. Even if there was, say, a 1500 mile trip to florida, if there is someone to visit along the way, I'll drive.

Anyway, the gist of it is that I think large planes or trips with water barriers are what the industry will end up with, I don't anticipate some massive groundswell of air travel demand for shorter flights in the long run.
Thanks for creating the spreadsheet. Discovered while banging head against docs and builds.

The feature should be emblazoned as experimental and advertised as seeking developers/funding, to protect ZFS reputation.
Sounds like who you're targeting right? Big corps don't need generalists, start ups do.
Per capita income doesn't reveal the actual income disparity. SF wasn't always expensive city to live. It was in fact quite the opposite. Last several decades have made the city inhospitable for the economically vulnerable population. Instead of looking at the per capita GDP, you should see the income distribution in the city. The median household income is $126,000 which is not a livable wage in the city for a family. The recent poverty rate is ~10%.

My perception is that, people were partying & were drunk. The Waymo vehicle likely was just passing through and probably got stuck. People simply took out their pent up frustration on it. It's nothing more than that.
Voting with your wallet obviously won’t work when going up against Alphabet. There is too much to gain in being the dominant market player and big tech companies have too much money to spend.
Started out an interesting read, but lost credibility with me with the "Hold Up" Gif.
True but certain traditional cultural events and norms seem to point to lifespans being much shorter than we generally experience them now to be.

Tons of human drivers would either panic, not notice or wouldn't know where nearest hospital is. Are we going with old trusty "can't do edge case X, entire thing is worthless" line of argumentation?
Housing isn't the sole factor in declining birthrates. Every industrialized nation is going through the same phenomenon and not all of them are having housing crises. It's a combination of various associated costs to raising children (housing, early childcare, food, schooling, extracurriculars, hobbies, etc.) that have risen faster than most people's wages. The nuclear family model also significantly diminished the role of parents and other senior relatives in early childcare which would've created significant savings in terms of both time and money.

Also, living without children or even a partner at all has become significantly more viable in the past 40+ years or so. It wasn't until 1974 when women in the United States could unconditionally open bank accounts out of their free will: https://en.wikipedia.org/wiki/Equal_Credit_Opportunity_Act. To not marry and have children would've practically been a form of ostracization. So many people, especially women, "settled" into marriage and family life simply because there was no other option. I think the decline in birth rates is a fair tradeoff to forcing fewer people into a lifestyle they did not want which would inevitably result in broken families and broken kids. What society needs to figure out is how to decouple productivity from raw human headcount, as well as how to avert potential humanitarian disasters that may occur when the decoupling happens.
Everyone keeps saying the story is great, but as someone that cares way more about gameplay than story I could not make it very far into this game. It plays basically like Operation Wolf, but in 3D. After being railroaded through a few shooting galleries I arrived at a level that was more difficult, and after failing a few times the game asked me if I wanted to switch to Easy Mode. Then I uninstalled it. Maybe the story is great, but I'd rather watch a movie or read a book for a good story.

> From the moral perspective, it is clear that WB clearly had real expenses. They spent money, bought rights, and tons of workers were paid good money.

Yes, they had expenses. You seem to have a very very rudimentary understanding of accounting and have conflated expenses with losses. An expense is not a loss. If you buy a factory for $1 million, you didn't lose $1 million dollars. You now have an asset, a factory, that is worth approximately $1 million. You don't get to go to the IRS and say "I lost $1 million dollars this year because I bought a factory". The IRS will tell you, no you didn't. You still have your $1 million, it's just now in the form of a factory instead of cash.

Likewise, WB spent money and created an asset, a film. That film has a market value. Maybe they don't like the film, but that doesn't change the reality that it's worth something. We know approximately how much it's worth because several other companies made offers to buy it.

Instead WB wants to lie and say it isn't worth anything. So, no I don't like how they are running their company when they want to lie and cheat to get out of paying the taxes they owe. You can't buy a factory for $1 million and then turn around and say "yeah, it's not worth anything anymore", and you shouldn't be able to say a movie isn't worth anything when it very clearly is. We do not gain anything by enabling companies or anyone to deny reality.
Shit, I thought the terrible twos were supposed to end some time.
Yes, they do. Their mission hasn’t changed since IANAs inception.

But getting a port assignment these days is going to be virtually impossible. It’s probably not going to happen without at least a Proposed Standard RFC.

There’s not a single RFC published that concerns redis. It’s not going to happen.
The problem arises when the obligation to exercise impinges on sleep time, whether that be having to get up early for a run or having to stay up late after chores to get a session done.

Sleep gives immediate benefits, exercise gives longer term benefits. It's a conundrum.
At that point they may as well ask for your horoscope chart and a scan of your palm.
> Something like 95% of all the stars that will ever be formed have already been formed.

Sure, but clearly civilizations don't exclusively develop around newly formed stars: we didn't. Most stars are red dwarves and will continue shining for trillions of years.
Oh my .. what a vivid idea.

Probably, most people don’t really care about inanimate objects or their well being unless they own them. I’ve seen people of all walks of life litter for no reason. Teenagers are much worse I see them tag the back seats of busses or just break things (or themselves) when they’re with their group of friends when they know they’ll look cool and most likely get away with it. To be young and dumb I guess
> More precisely, our results show a cost of $4.15 billion if society had to replace these packages once (e.g., OSS still exists, but all of the most widely used packages were deleted and had to be rewritten)

I realize estimating anything numerically here is tough but that number just seems low by an order of magnitude or more. $4 billion is less than the cost to build one aircraft carrier. It's 1/3 the cost to build the Abraj Al Bait tower in Saudi Arabia. It's like 3% of the net worth of Bezos, Musk, Eliison, or Zuckerberg.

Recreating Linux alone would be a massive endeavor, taking hundreds of people many years, to say nothing of gcc and clang and git, and those are just the developer tools needed to build all the other stuff. Estimating $300,000 per developer (including salary + benefits + office space + computers), $4 billion is 13,000 person-years. Google has about 26,000 developers, so it's saying Google could recreate all open source software in 6 months. Or one tenth of Google could recreate all open source software in 5 years. Not that I have a better way of estimating, but the number doesn't seem realistic.
>Their biggest challenge will be competition, and that makes it highly uncertain. It’s a very _risky_ stock, but the potential upside is very high. It is not a bubble if the price is driven by expectations of earnings growth.

OpenAI isn't a stock. It's a private valuation.

I actually think they'd be well above $100b if they're a public company right now. Just look at how much $MS added in market cap since ChatGPT.

Sure .. although some of those children will be older than the people they look after.

This morning my father delivered "Meals on Wheels" to 20 other elderly locals.

> There has been a significant decrease in desktops in the last decade.

Indeed, but not because phones have gotten any closer to desktop work.

What good is a phone, today, when using multiple monitors for 3d modelling, video editing, programming, spreadsheets, flight sims, or some such? None whatsoever.

And there's no apparent trend toward it, so it doesn't make much sense to predict when it will be reached.

Desktop usage will likely continue to decline as phones, tablets, VR, and whatever other devices continue to supplant them _in certain areas_, but that's insufficient to render them obsolete.
I wasn't trying to make a $modernpoliticalanalogy. I was speaking from painful personal experience that may be biasing me to think this is more frequent than it really is.

Yes, they say they needed to search for a reason but I think we'll find none of these people ever have charges (related to the search warrant) filed against them. And that's the system: pretend the methods needed and used for real criminals need to be applied to people committing no crimes.
Or it could be saying this is normal expected lawlessness rather than further lawlessness.

People write about Remarkable like about hardware company but my impression is that it's a very small venture, and pushing out RM2 took their strength financially. Preorders in 2017, released in 2020, and all they could do since is release a keyboard cover. The software is really restricted, updates abysmal, stillnbugs left. Most things come from the small diehard fanbase. Their edge is that somehow nobody really attempted to create a true competitor - there are epaper tablets with pens, but not with this quality or services. The industry kind of hates epaper. Pebble - a company that had much better relation to its community, and a larger portfolio of products - couldn't make it, I don't see how they could.

Expect rhetoric out of both political parties over regulation, which will cause additional volatility. Expect a deal between Nvidia and Apple. Apple is behind the curve. Both companies want to control ARM.
