I think systemd is useful, but I think the implementation is not very good.

some observations:

- /etc/systemd is disorganized. config files, directories and links all thrown together. It's like they started with the init.d / rcN.d directories but then threw everything in one directory. This is as mindful as a kid throwing everything in the closet to organize his bedroom.

- /lib/systemd is worse. binaries, links, configs. unraveling all the dependencies... 450 small pieces of spaghetti intertwined.

- Having binaries seems like premature optimization (root of all evil). And they're probably not faster, but are definitely more opaque, and much less likely to evolve. It's sort of anti-unix.

- the config files, which trace their mirrors windows .ini files, allow no intelligence. Giving it the benefit of the doubt, say maybe dumb config files can be autogenerated, I still get sad. Logic still has to be there, but you still require an intermediate script or maybe bake it into a binary.

- scope. It is like the borg. Or an episode of hoarders.

apart from documentation, it would be nice to have example config files for the most common scenarios.

Nothing is elegant here. It's all "works for me" level mediocrity.

This is true with encrypted credentials, if security is compromised by release of the repo then the encryption is not secure. I think the spirit of the principle is met, and in cases where you do later release the source code without having planned for it, it's easy enough to move the secrets.

It's definitely more convenient to use the same repo, especially in the declarative containerized world; you can make sweeping changes or roll them back in a single atomic commit.

That said, if open source is the intent, certainly use multiple repos from the beginning so you avoid git gardening when releasing later.

Bill Gates: People would use Windows Mobile if not for antitrust case
I don't think Apple or Microsoft's (released) AR stuff can be used for VR. Apple's ARKit just runs on a phone screen (which obviously isn't AR) and HoloLens doesn't have the field of view to be VR. So they'll probably converge eventually but the products right now solve one or the other, but not both.
These stories seem so weird to me! Everywhere I’ve worked, there has been 3-5X more development work needed to do than engineers to do it, so we had to always be prioritizing and only doing what absolutely was necessary to ship. Is there not even a bug backlog where you work? I’ve never seen a workplace like this honestly!

Unless you’re taking a 2 week task and estimating 2 years or something, and then just goofing off in the slack time, which I’d consider... somewhat less than ethical?

Academia is almost entirely based on trust and reputation, which we're seeming to discover is not a useful heuristic if your end goal is a net gain in uncovering the truth of the phenomena around us. If you ask me, credibility should be based on reproduction of results rather than reputation of the author, name of the sponsoring institution, journal title, or a vague "peer reviewed" badge. New papers should be by-default untrusted until several reproduction attempts have been successfully executed. This would incentivize authors and scientific institutions to produce science of quantifiable quality.

Every domesticated animal is like this. (I'm not including animals like e.g. goldfish because ISTM there important ways in which they are not domesticated.) The other important aspect is that members of any particular species or lineage within a species have largely the same behaviors. Training and experience might add useful behaviors, but they don't completely eliminate existing behaviors.

For instance, cattle have a way of existence in which they are comfortable. (They really don't like anyone directly behind them, but off the rear quarter is tolerable. Structure like a fence or a road makes it easier for them to walk in a straight line. A single animal might be comfortable in isolation most of the time, but will seek to join a group when stressed. A path that is comfortable at a given speed will not be followed at a higher speed. Etc.) One person who understands that way and is willing to work within it can move a large herd more quickly and easily than twenty ignorant people.

ISTM human beings are also "domesticated", although they display a broader range of interesting behaviors than other domesticated animals do.

In a certain US jurisdiction I have a room with a bed in it I can call a “nanny’s room” but I cannot call a bedroom on a real estate listing, as the closet for that room is through another door in a sort of hall.

In Europe though, where armoires are a thing, and I actually can’t remember living in any home that had a closet in any room with a bed, I don’t see closet being in the definition.
That's a really good heuristic, but unfortunately, lots of users are still stuck in the "I need an exhaustive list of all of our data, ever"-mindset because that's what their manager mandates. Then they print it and put it in a drawer. shrug
I liked the access controls at PayPal. Access to data was a function of insider status with real financial consequences (ability to sell stock was restricted much more for higher level insiders), subject to strict controls and auditing, and required need-to-know periodic renewals. I used to think PayPal was fly by night but my work experience there really grew my trust in their access controls and made me much more likely to use them for payment.
When I worked for a department that had a rotating on-call person, if they didn't answer the call, then it was escalated up the chain, and sometimes that in fact happened. Nobody was actually making $300K, I don't think, but still, management was effectively always on call, just with less odds.
Yes, I mean today's nuclear. But for solar/wind I mean what I said above: enough storage for a windless night and enough overcapacity for cloudy winter weeks, so it's the cost to actually run a grid on wind/solar/storage alone.
You know, I don't usually like this quote when people deploy it, because it rarely applies. Frankly I find it questionable even in the original movie. But it applies here like gangbusters: "Your scientists were so preoccupied with whether or not they could that they didn't stop to think if they should."

There are a lot of commenters here who seem to be operating on a subconscious presumption that being "the best we could do" is some sort of defense. It's not. If the best you can do is not good enough, don't deploy it.

> Wait, in the US you use 15A at 120v? Here in Europe (Spain at least) the typical is 16A at 240v.

Yep! The typical US residential circuit is only 120v, 15A breaker (so 12A at 80% load). (And that may be only 110-120v.) 20A circuits are also fairly common, but it's not the most common; the majority of wall outlets in a US house will be 15A.

In this chart, https://en.wikipedia.org/wiki/NEMA_connector#/media/File:NEM... , the commonly used US residential sockets are NEMA 5-15 (labelled "Typical Outlet," for 15A breaker circuits), NEMA 5-20 (for, duh, 20A breaker circuits), and NEMA 1-15 ("Old Outlet," in older buildings).

> 1500W isn't that much of a problem. Oven breakers are even 20 or 32A.

We do have higher amperage circuits for appliances like ovens and clothes driers, but they're usually dedicated circuits and have different socket shapes. You can see the labels "Clothes Dryer" and "Electric Oven" in the chart linked above :-).
Totally agreed. Please fund us enough to do replication at that level.

(Although, at least in my field, replication is gives less bang for the buck than improved measurements. If I measure a thing, and then you measure it with 10x higher precision, you're not just replicating my result, you're moving the field forward.)
So using your analogy, the people who were there first that you are trying to displace by pricing them out of the market are the Native Americans.

> The idea behind community-based development is that anyone can provide a business around the output of others

I disagree with this statement. Being able to build a business around the output of others is a side effect, and not the primary reason for open source. I would argue, and many companies are arguing, that the side effect causes more harm than good, and there should be some kind of optional middle ground.

> the development team was very insular and ended up all at the same company

Look, I have no statistics around contributors that are employees vs contributors from other companies. Zeeg may have an idea. But as he said up-thread, they tend to hire those that contribute.

Operating Sentry at scale is no small feat, and I'm not surprised that most companies prefer to spend the money on the SAAS solution rather than on employees to operate it.

> so they ultimately saw no benefit to participate in the wider community

This is the bit I most disagree with. They are still participating in the wider community in the vast majority of cases. There is a single restriction - you may not take the output and duplicate their business.
IMO it's the other way around, AR is a special case of VR. To make an AR system, you need to basically do all the work involved in making a VR system, then somehow integrate it with a video feed of the outside world, then convincingly add digital content to that video feed in a way that complies with the real world's geometry, which you have to extrapolate from the video. Basically it's much easier to accurately place virtual objects in a virtual world than it is to put virtual objects in the real world. You know the geometry of the virtual world but can only make educated guesses about the geometry of the real world.
I agree that it's good to evaluate what's the best thing to do right now to reduce suffering. I don't believe that extreme forms of redistribution work, and we do have redistribution in the form of taxes right now.

> now more than ever, a lot of the productive capacity of money is being needlessly accrued by relatively few people who, on average, don't possess the the knowledge or will to apply that capacity to society's problems. Under those conditions, the potential for growth and productivity in the future is needlessly limited.

The people who accrue a lot of money is able to do that because either they profit by selling some useful product or service that others desire and buy, or because they invest some land or form of private property they bought or inherited, or because they steal or acquire by illegal means that harm others (like corruption). I don't believe that we should consider equally the rich businessmen who became rich providing something useful to the world, and the corrupts. If the good businessman is punished with taxes or confiscatory laws he would be less able to produce something useful and demanded by society. If the corrupts are punished, everyone wins.
Perhaps true. But the original cool thing about Twitter was that you could tweet just by texting the twitter number from your dumb phone. The service literally required your phone number, and made broadcast information happen in real-time before smartphones really were ubiquitous. Many messenger apps still use/link people through their numbers. While it is possible to not require numbers, and services like Facebook surely never needed it, there are times when providing phone numbers really reduces friction in communication.
That economists make mistakes, and that even well-regarded economists espouse simplistic models, is not evidence that physicists might be any better at it.

I find my home cluster to be laughably easy to set up, and I am still new to home clusters. This is an area of rapid development. I could wipe the hard drives and have it back up in less than 30 minutes, not counting the time to rewrite the OS images. I just have some machines running Ubuntu Server with one running Ubuntu Desktop (just because I like it). Each node needs a single shell command and it’s good to go. In the past I have done things like using interface forwarding to allow every node to use a hard drive that is connected to the master so if I ever actually have a use for that or if I want the master to act as a DHCP server and forward its network interface to the workers I can do it again.

To maintain portability you need to pay attention to CPU architecture and the underlying OS. Just make sure that your images are built for the same architecture that you will use in the cloud and that you have the right OS and version. x86_64 is ubiquitous (I think AWS offers an ARM server option, though) so developing on a Raspberry Pi cluster might be a headache to deploy.

For production you will want to use a cloud provider (or not, it’s not the craziest idea to run a home server if your use case permits) and you can do so for development if you can afford it.

The real advantages are service discovery, monitoring options, stateful support and resource allocation. I used Kubernetes Up and Running 2nd Edition, and if you don’t know Docker yet I would work through the Docker Book first because you will want to write your own images. Just make sure that everything lives in the same repository: a single filesystem as the single source of truth.
The problem is that it’s a mismatch between wealth and income. Property taxes are taken from income, and if your income doesn’t increase in line with property taxes that may rise completely out of your control, you essentially may have to sell your house to pay property taxes. That doesn’t seem like a good solution to me.

I was thinking on the way home that maybe you lock property taxes in but then you have to lock your home price as well, but that probably wouldn’t work.

With respect to your last sentence, I think one of the issues is that we actually mix public policy into home prices. You can’t want a free market and also not want a free market. It seems like many home owners have chosen to not have a free market when it comes to home prices. It’s also not helpful because, like medicine, your home is a big deal. Uprooting you’re family is a big deal. Think about how a family feels if they buy a house, all of a sudden their neighborhood is “cool” and then they have to uproot their family because rich people push them out?

Not a lot of good solutions to a big problem here.
Exactly, it can be treated as an example. It's an npm package so that I can reuse the code :)
Plenty of people are happy using the industry-standard open-source tools:

- metrics system (Prometheus, InfluxDB, Graphite, etc.)

- dashboards (Grafana)

- alerts (both the metrics system and Grafana can handle this)

If you're not a big-data company, you can self-host instances of these products reliably.

I still don't quite understand why I can't strap myself to my existing phone with a couple of periscopes, run an app outputting the two images on the left and the right halves, and control it with some bluetooth joypad.
Not at all. They are completely different problems, both from technical and product perspectives.

VR is all about total immersion - sights, sounds, movements and everything else. The entire world needs to be contained in the headset, and what's happening outside it is irrelevant.

AR, on the other hand, is about interacting with your surroundings. Immersion is cut down, but the system now has to be intelligent about the outside world - recognizing objects, projecting at the right places etc.
No. It was not good.
Google was actually the first company to release an AR-capable phone, with depth sensing capabilities, back in 2014[0]. Due to their inability to properly market the device (or maybe the market wasn't ready at the time), they cut back on that division. One of Google's big tactical mistakes, imo.

However, spreading past Earth or transcending to entirely new ways of existing (e.g. computational life) are also possible

The leap to another planet is far, far greater than to a new continent. It is an open question whether or not we could achieve it at all before a crisis destroys our civilization to an extent we may never recover from. There can be no second fossil fuel revolution, that was a onetime event in Earth’s history.

But setting aside the challenge, with new possibilities come new opportunities for inequality. In the case of the former, it’s not difficult to imagine a wealthy person owning an entire planet. In the case of the latter, might I suggest the short story Incarnation Day [1] by Walter Jon Williams. In a world of finite resources and computational life, perhaps only the wealthy and privileged can afford to be incarnated.

No? ~$100 is remarkably cheap for a new motherboard, especially if you are complaining about needing 32+GB of RAM, which costs substantially more than $40. If you want something like a $35 Raspberry pi, buy one and accept its limitations.

Thats absurd. Civil tort never results in jail time unless someone commits a criminal offense during the proceedings such as perjury or contempt.

At most AirBNB would have to prove damages, which would be difficult since they profit off dishonesty, or have proceedings that result in consequences for the hosts.

For example I’ve had multiple hosts that lie about the address of their tenancy because they’re renting and not allowed to sublet or short term rent the property as a term of their lease.

Verifying the listings, including deeds/leases would fix this.

Really? Why not?
Fair enough, it’s possible, but I maintain: the model proposed would have been operative always and everywhere, so would we not expect this to be occurring all of the time? Would history not be very different, with no middle class (our middle class has only recently declined)? Wouldn’t extended periods of broad prosperity would be an aberration, rather than the broad stroke of history?
