This is a bit of a misunderstood overreaction.

It's true that if you were playing Super Mario on your TV, the normal experience was for it to be a bit blurry.

On the other hand, if you were playing Lemmings on an Apple monitor with Sony Trinitron technology, the pixels were exceptionally clear. Here's what Trinitron looked like:

I'd argue that playing Lemmings in an emulator, you want the pixels to be clear, without a CRT overlay -- that this would be closer to the artists' intentions.
The problem is keeping those diagrams correct. I've worked where the UML was the code, and it worked because the visual models were up to date. Every monday I'd print on poster sized paper the latest models to paste on my cube wall. They were good enough for the rest of the week, but by the next week there were different enough as to be worthless.

I've never seen UML actually work anyplace else. Either the models are out of date, or they are only up to date because you force people to go back to maintain the models after the code is working. This latter of course fails, why would management want to pay someone do maintain models when not only is the code working (well at least partially) for the testers, but the person who is assigned to do it doesn't want to.
I'm curious about the name. Putting "DB" in the name sort of suggests it might support persistence, more data than fits in memory, write-through, etc. Is that the case? Or is the "DB" some nod that clustering means that "in-memory" doesn't have to be ephemeral?

Or in short, where is KeyDB headed, longer term?

Ah, no. Neutron stars have some kind of average density. That's ... not applicable to black holes in any real sense. Their sizes would not change and are pre-determined by a relatively simple formula in the case of non-rotating black holes without any significant charge.

Nice. I actually think is the first application of blockchain I've seen posted here that makes some sense. Cut out title companies and no need for storing paper deeds in a courthouse somewhere.

Still, a lot of the listed benefits don't clearly follow. Communication on the blockchain isn't any faster than communication via email and phone, so I'm not sure what that's getting at. The slow speed of approving people for mortgages isn't going to change because the bottleneck there is usually the applicant finding and gathering all the records they need, which won't be on the same blockchain. Similarly, the issues caused by unstructured data don't go away when you swap out the storage backend. Putting a schema and API on top of this to make the data automatically accessible to downstream consumers without needing a human to parse it needs to happen at a layer above the blockchain itself.

I told macOS to run that program because I trust it. If macOS trusts me then it transitively trusts the program I told it to run.

In other words macOS doesn't trust me to validate programs before I try to run them.

After seeing a few of your replies on this thread I'd like to comment on this: what I see is someone who's using their own personal beliefs as justification on why something isn't useful, failing to understand others have their own beliefs and situations that make the technology useful to them.

For me, and others, there is a deep value in a decentralized, fault tolerant, fast, global, user controlled, immutable ledger of payments and store of value. You might argue that we have existing centralized solutions to these problems, which you believe are better, but that doesn't invalidate the inherit value I (and others) attribute to such a system. Being able to transact across the world in seconds for less than a bank wire and without a central authority is useful. Yes a centralized authority like PayPal can do it faster and with less resources, no that doesn't mean the decentralized method is useless.

We should never be a factor to them but our egos require us to imagine they are thinking about us at all

The only time they acknowledge us is to placate our egos. Reassure us that it isn't a big deal that their economy is about to be larger, and reassure us that they wont do the same things we all did with the rest of the world (and hope we ignore what they do internally, they aren't sending drones for our domestic rights abuses either).

The problem is system analyst is a useful job only if they don't have to worry about all the details of the helpers and incidental data field and can focus on the high level parts that matter. In the mean time programmers need to add those little helper classes as implementation details, and they instead of to spend a week doing some formal request to the system analyst for something that could be done in an hour if they were allowed to think. And of course programmers have to think anyway.

One problem is that there are many such visualizations, each of which has its own advantages and disadvantages for specific purposes. Visual syntaxes also scale very badly with increasing complexity, so it's very unlikely that a "large project" could be usefully represented by a handful of diagrams. UML seemed to have very clear problems due to both of these issues.
Just to point out - you've listed two diagram types. There are 14.

Of those two (which are the only two I've heard called out by their name in any business context), I've not seen consistent notation. Sometimes it's a problem, sometimes it isn't, but invariably what is more important is the conversation happening alongside the diagram; the diagram by itself is not a useful artifact, just like the slides to a (good) presentation, by themselves, are not useful.
I'll give this a shot, thanks!
I just upgraded from Fedora 33 to Fedora 34 and experienced serious issues making my computer usable. There is a rendering issue making the screen flicker/strange pixels patterns appearing for almost every app (including gnome terminal). Interestingly, the only app that seems unaffected is firefox.

The only non-standard thing about my setup is that I have a 1400p 144hz display. My graphics card is Amd 5600xt so I do not think this is the issue.

Has anyone else experienced this?

I am not a sophisticated linux user, but I have been using Fedora for the last 10 years without issue, and usually upgrade when I hear about a new version.

Yes, I'm sure Google will carefully release details that paint them as the good guy. Certainly, we don't want to be needlessly unfair to them, but there is zero reason to give them free trust them at this point.
It’s absolutely true. In many ways. Although in this case, a poor person could reap the same benefits. The only requirement would be good credit and payments/financial discipline. I know those things are generally inversely correlated but just wanted to point out you don’t have to be wealthy to get a cash back credit card.

Thankyou for that really detailed explanation. That reaffirms for me that I will most likely stick with aircrete and concrete/shotcrete when it comes time to build a few hobby structures I had in mind.

Out of curiosity, could you suggest what material would be best for storing heat from the sun? I am going to build a greenhouse that will face the south and have a wall on the north side to absorb heat. I have seen some people use clay with a black metal wall and some use black barrels of water. I want to be able to extract some heat from it using pipes. Any thoughts on what might be even better?

OP here. It's hard to make the case internally to switch to an orchestration platform that works for "most of our apps".

Of course, it's similarly hard to make the case for WASM, which is similarly incomplete today; however, there appears to be mutual interest from language communities and the WASM team to get support working. Even still, I don't intend to make the case until WASM has a decent track record of supporting those languages. But I have more optimism that WASM will get there than JVM or CLI.

Note also that while "JVM and CLI have support for those languages", their support for Python (and probably JavaScript) is only nominal. You can't reasonably use Jython or IronPython with the rest of the Python ecosystem, but WASM at least has a plausible path forward. I also strongly suspect that support for sandbox execution of the other languages is similarly nominal--if it's technically possible, I'd be surprised if anyone is doing this in practice.

As long as you're not flying an experimental aircraft, general aviation is naturally safer than diving. Since GA planes are aerodynamically stable and can glide, pilots (usually) have a lot more time to calm down and think through their options before the situation becomes really dangerous. Most emergencies can be resolved by identifying a flat field or calling an emergency at the nearest airport (which the FAA is encouraging pilots to do more often). Not to mention, getting a pilots license is about 10 hours of "how to fly a plane" and 30+ hours of "how to deal with emergencies" including the instructor cutting off engine power mid flight. There's a procedure for just about every situation and the most important ones are practically muscle memory by the time one receives a pilots license.
I didn't imply that 3d printing should fix the materials problem, I simply hope that the materials problem gives 3d printed housing enough room financially to achieve economies of scale to bring the prices down for those situations where 3d printed houses are specifically relevant.

Consider as one example low income areas that are filled with housing built in the 40's and 50's which can now be razed and replaced without inadvertently causing gentrification.

The problem wasn't the idea, a visual diagram for logic flow is a good idea but your IDE can do that from your code better than the over-engineered idea of UML. UML had another problem, it reversed the way programmers work. As a programmer you start with a rough sketch (hand drawn diagrams and/or some prototype code) and iterate through that along with the client until you have what they want. UML (at least the way it was taught in my university) assumed that the client knew exactly what he wanted and that as a developer you could get your system designed perfectly on a diagram before writing a single line of code. When you tried to translate that into code you realized that your design wasn't as good as you thought, you had to make changes and doing that required going through a lot of bureaucracy (and change requests) that only served to hinder your progress. The automatic code generation promised by Rational wasn't as good as promised, it was close to useless and their software and UML basically expected you to program in enterprise Java, trying to fit a less enterprise OO language there was pure pain and resulted in very messy designs.
I wonder if there is an added benefit to this policy in terms of required geolocation for access. As in, will Apple prevent apps from requiring geolocation for access to content such as the MLB, NFL, or other apps that will only show content specific to your market area.

> "[...] and you can't withhold functionality or content or make your app unusable until people allow you to track them."

Per that reading, it would seem like the MLB and NFL apps would be banned from requiring location access before the live streams are playable, which could finally progress some of these insanely stupid TV blackout rules once and for all... Though, unless Apple will also apply this to IP based geofencing, there would still be a long way to go before TV blackout rules are gone from streaming services....
The goals distinguishing from other init systems seem to be:

- musl support

- guaranteed bootability

It's not easy to extract this from the post, since it's hidden between value statements like "flexible", "small", "fast", "unpredictable", which aren't defined anywhere, nor supported with external statements.

Since those aren't defined, it's also not clear why the author didn't decide to contribute support for the two defined criteria to systemd.
Which is why sketch UML is popular. It looks like UML if you squint and gets the important reasons to use UML on a whiteboard. Then after everyone agrees you erase the whiteboard.

How would SSDB compare to using etcd? They both are disk backed key-value stores, but SSDB doesn't seem to be under active maintenance, with most of the recent merges being about fixing build issues.
On the Windows side you can find Windows Hello certified third party cameras with the necessary IR and depth sensors. (I've seen Intel and Logitech options in stores.) Since the death of the Kinect the cost has generally gone way back up as it is a niche of a niche just to support easier logins and few applications anymore are using the IR/depth sensors as much (though even this far past the Kinect, Windows itself has additional eye tracking/attention tracking features these days than it ever had before for accessibility reasons).

Surely Apple could release a FaceID-compatible USB webcam if they wished. It's probably less likely for them to FaceID certify third party hardware, though.

(That said, I think Apple's other excuse for not supporting FaceID on more hardware is it uses the ML capabilities of some of their mobile A* chipsets. Maybe another thing they might claim can only be done with M1+ macOS.)
Uhh, the solution is not so simple. Small businesses are often on a very tight budget. That unemployment checks are currently paying a lot more than a large set of wages would has resulted in a shrinking worker pool, further complicating matters.
It seems strange that there is so much focus on 3D printing structures. Any close look at where the costs go in home construction can easily verify that foundations and services (power, water, sewage) are where the majority of the costs are. It always makes sense to pinch pennies, but starting with one of the smallest line items limits potential improvement. What we really need are ongoing improvements to modular service installations.

This is also a complex cultural problem here as well because even though there are obvious ways of making even comparisons such as time and money spent before receiving a use permit the culture of construction likes to focus on a single innovation while leaving the rest out. There is a modular apartment building near me that took only hours to assemble from the component modules. However, doing that took many months of site preparation and module delivery and after the several hours construction it has still been months to get finishing done, construct sidewalks, and the rest. Without some general agreement about how to measure construction costs and time it is easy to present innovations that are either minor improvements or actually steps backward.
it's got Google Drive integration too. I use it and put all the diagrams into a Google Drive folder.
Yes, and there are a number of other examples like that. But that doesn't detract from the general case in the least: if energy can be saved then it usually will be saved, especially if a mechanism lasts for a long time. The idea that the base mechanism of encoding life patterns is going to be on the order of 70% or more 'junk' requires a very good explanation. Why the argument presented here is invalid I'll leave for you to figure out.

Ah, I was thinking of a soft breakpoint, not a hard one.

A hardware breakpoint solves the threading problem, but it doesn't stop the external world. If there are external events that your system responds to (and what embedded system doesn't?) then those events will either be missed, or else all queued up, when you resume.

Shoving chars out a uart, in contrast, takes time, but considerably less time than a human hitting continue after a breakpoint. That can still mess up the timing. But a breakpoint absolutely blows up the timing - seconds worth of external events have happened.

If your external events are coming from a test rig, and the test rig is aware of you hitting a breakpoint, then that problem goes away.
