About the only thing that regularly wears out is spinning drives, and those have SMART data to give you an idea of when they'll die, but generally yif you're actually committing to high uptime you'll have redundant hardware so any one server failing doesn't take the service down, giving a bit of a grace period on hardware failures

Hey, good luck! I've had some depressive episodes where I couldn't do work or even good off for a good week or so, but I'm privileged to have not been chronically depressed and need medication (I have others issues and working on those have prevented episodes). Going to therapy was the best decision of my life, and this year I've progressed enough that I put in almost 100 hours over 7 days for one critical project (which isn't something you should be able to brag about lol, but I'm proud of myself; a year ago I would've had a breakdown on about day 2). It's a journey though, and you'll have good weeks and bad, so just keep in mind that even if this week seems bad, next year's gonna be great!

Generally it doesn't make sense, but in this particular case the servers are going ti be so overloaded with people trying to download it that it might be worth it to preloaded the game. Now of course they're probably going to have separate author servers that will probably also be overloaded with everyone trying to login at once (why does a single player game need you to log in first? good question!) so imo you're probably going to be screwed either way

Chaosnet (1981) 1 month ago

It says it was inspired by Ethernet, and while modern Ethernet might have some significant differences of course, what were the differences between Chaosnet and the Ethernet of the time?

nerds built companies largely as a byproduct of their own interests. they made a lot of money because their technologies were great, but it was always about the tech, not the person. then vcs came in and convinced themselves that actually it was about the person, and started deploying money based on the people instead of the technology

I have a couple like that in my mini rack. The problem is the power supply: these take 65W, so I figured I could get a quality 140W charger and power them both, but it turns out that things like "unplugging something else" would kill their power. I had to spend a lot more on a StarTech charger to get the performance I needed

There's a lot of people talking about the technical aspects of AI, but I think the (for a lack of a better term) marketing of AI is just as important. Insisting that anyone who is anti-AI is on the wrong side of history does not tend to make people who leaned in that direction reconsider their opinions, it tends to make them think that pro-AI people are arrogant and thus push them even further towards being anti-AI.

This is even bigger with AI because of a couple of other recent trends that have been marketed the exact same way and have failed to live up to the hype: cryptocurrencies ("have fun being poor"), NFTs, the metaverse, etc. None of these have turned out to be the absolute use-this-or-you'll-be-unable-to-participate-in-society level changes that their proponents have claimed. Now AI proponents are making the same claims, but people have seen that the last few times this has been claimed (often by the same people) and therefore don't believe the new claims.

Fundamentally the point of DNS versus Ansible updating /etc/hosts is the same: get a mapping from DNS named to IPs to the client. As such, Ansible will have all the same issues. Plus, it'll introduce its own issues, like the fact that /etc/hosts is effectively cached DNS with an infinite TTL

Changes from a single point of failure to a thousand points of failure. What if a host if offline when the Ansible update runs? What if someone wants to run a service that ignores /etc/hosts, like a Docker container?

The OS was smooth and worked well, and the design philosophy across basically every app was extremely coherent. Everything worked well, and everything felt like it fit together. Really its only problem was the lack of apps due to companies intentionally not supporting Windows Phone (Microsoft had a YouTube client that Google made them kill off, and Google never bothered to release a replacement IIRC)

Missiles versus aircraft is a fight between very high kinetic energy in the missile, and relatively low kinetic energy in the plane, but with the ability to generate more kinetic energy. Missiles don't have a lot of fuel, so they need to generate a lot of kinetic energy to still be effective by the time they reach the target. Typically a missile will accelerate to its top speed in the first few seconds of flight and coast the rest of the way. At very long ranges, all the energy generated when launched has bled off, so there's two common solutions for long-range missiles to generate more energy: a "dual pulse" motor is basically a second rocket motor that fires later in the course; or a ramjet, which can be throttled up and down and is more fuel efficient than a rocket engine.
