> Interesting, but surely snapshots are only needed for connections with active transactions?

Right, but the problem is that the cost to compute them essentially scales with the number of active connections (and to some degree with the number of allowed connections). Which means if your system actually does things, all those idle connections cost. We can, and should, make the constant factor for computing this considerably smaller. But obviously larger architectural issues need to be addressed too, at some point..

Edit: expand.
It's funny that you make these suggestions, because they're all things we're grappling with/considering at the moment.

Until now, most of our work has been supply-driven: we write and work on what we think people want to know rather than actually asking them. This has probably been a mistake. We're really changing the way we work to be more demand-driven. This means possibly having some kind of area where people can ask questions, have discussions etc. It's definitely something we're considering.

And you're also right that we need to work on the connectivity between aspects of the site. We're in the middle of trying different designs and formats to try to nail down the best way to do this.
Yes, this happens through a process that Porges calls "neuroception" (easy to google). Essentially the subconscious part of your nervous system, especially the brainstem constantly scans your environment for threats of any kind (it takes in incredible detail, some say 1000s of times per second without it ever bubbling up to your conscious mind).

Here's an example: You see a tiger in the forest. Your eyes send that signal through their nerves to the brainstem, which makes your stomach tight and activates your legs to run away. The tight stomach and running legs then send their signals of movement and clenching back up through to limbic system ("I'm scared!") and the neocortex (your conscious brain, "I'm running away from the tiger!") to tell it to run. Because all of this happens so fast, our experience is this: We saw the tiger and therefore we're scared and are running away. That's not really what's happening under the hood, we're scared BECAUSE we're running and have a tight gut, the tiger was just a trigger for the brainstem/gut/legs. Makes sense?

There is some stuff in post that is somewhat useful, but the conviction of the statements is a bit much. Nothing in the brain is simple, and most of neuroscience is in it's infancy today. Dandy-Walker syndrome is an especially extreme, but illustrative, case of how strange the brain can be on the inside, yet present as normal on the outside[0].

If independent researchers don’t like that they should come up with a way to train resnet in 1 minute on a single GPU.

FWIW, I have the same symptoms in winter, but none of the reasons you list apply to me. I can easily see SAD being caused by lack of natural light, and I try to spend as much time as possible in sunlight (which is hard given a normal work schedule).
I don't know. First we'd have to identify if there is one center of the universe; can we guarantee that the universe expands uniformly? I can't find anything online and I'm not a physicist. If there are multiple centroids of the universe, and they're all moving, we probably can't establish an eternal reference point.

Also I think the confidence interval for instrumentation looking that far ahead would be so big comparative to current/possible local solutions, we're probably better off doing something in the Solar System instead.

One advantage of synchronizing to some reference in the Solar System, and maybe setting clock boosters as floating checkpoints in space, is we will always be able to find our way home :)

I would add early morning sunlight helps regulate circadian rhythm.
Yeah I think it really varies by the region. Sure it's good to go outside in Sweden and England, but not in Aussie and NZ when you can get sunburn in about 15 minutes.

I've had couple of barbecue parties this summer in Auckland and NOBODY went outside until sun was way past 5PM. We preferred to sit in stuffy kitchen rather than enjoy beautiful beautiful outdoors. Even in middle of winter you can feel sun bite you as you stand in front of pedestrian crossing.

"The subtitles for Mixtec dialogue appear between brackets, while those for Spanish are in standard font. Apart from the fact that this confers a different value on each language, it hinders readability and is a convention never used in French subtitles. It would have been conceivable to use two different colors, but that too would constitute a distraction from the story itself. The most logical option would have been to trust the audience to hear the difference and get used to it through the narration."

They did this for the English version too, and I'm glad they did it. At least on first viewing, I doubt I would have picked up on the two dialects, and it's important to the plot to know there is a difference.

The rest of the article doesn't give enough context to the mistranslations for me to be outraged.
Just used the elementaryOS files app to access my Nextcloud server. A while back it used to be terribly slow but it's actually incredibly useable now. It's a shame this protocol has been shunned. I believe Microsoft Exchange used to support WebDAV for email access...
No, that is false. DNS registrars do not sign CA certificates and, without DANE, are not trust anchors in the WebPKI. And, of course, with DANE, they would essentially gain that status. This is a plain fact, but you can reason your way to it axiomatically by (again) considering how trust would be rescinded: Google singlehandedly killed the web's largest CA after a misissuance, but obviously cannot do that to .COM in a DANE world.

When your argument starts depending on redefinitions of well-established concepts, that's a sign that you should reconsider it.
Last month I tried to use Reed Solomon ECC in order to do error correction. I stopped using it, the moment I understand that error correction does not necessarily mean "error detection". If one does not exactly know the number of possible errors within encoded data, RS-ECC may "correct" to a wrong result (if the data contains more errors than the ECC is able to correct). So checksums might be the better approach (in certain scenarios) if data integrity has the highest priority... I wish, Reed-Solomon would handle that.

> I don't know how MySQL behaves in this regard, but in Postgres the number of transactions the system can run concurrently is roughly limited by the number of CPUs you have available. At some point adding more sessions just means that you will just end up with more lock contention, context switches and RAM usage.

That's only true if your transactions are all busy most of the time. Which in a lot of OLTPish workloads isn't actually the case. Both latency and the fact that applications need time to process such queries ensure that. IOW, I think this is better phrased as concurrently running queries, rather than concurrent transactions.
Is it really that much of a paradox?

- "Metallicity": We probably need a recent / "Population I" star, i.e. it' s probably unlikely that there can be civilizations much older than us (in astronomical dimensions): https://en.wikipedia.org/wiki/Stellar_population#Population_...

- In 1.1 billion years from now, the Sun will be 10% brighter than it is today, and this increase in luminosity will also mean an increase in heat energy, which Earth’s atmosphere will absorb. This will trigger a moist greenhouse effect here on Earth that is similar to the runaway warming that turned Venus into the hellish environment we see there today. So we have appeared only after 80% of the "usable" life span of our star has already been over -- a window that might be easy to miss (an larger stars burn even faster)

The problem in California is that none of the folks involved in building it think finishing it would really benefit them. I've had family members involved in numerous public works projects in California, and once they saw the way the sausage is made, all decided to get out.

These projects are setup as a way to extract money from taxpayers, through a relatively well developed process now:
1) Write an initiative/tax statement which promises the world.
2) Once it passes, laugh and start doing engineering planning based on the most naive/known to be wrong set of assumptions.
3) Once you hit the first roadblock, escalate it and require change orders ($$). This often doesn't require doing any actual on the ground construction work. In fact, many of these boondogles (Caltrain electrification?) never hit actual construction after 5-10 yrs of this.
4) Redo the entire set of plans at great expense, but without actual forward thinking. Hit the next roadblock, rinse and repeat prior steps.

This allows them to funnel billions into friendly firms that produce plans that never get used, doing studies that no one will read.

Since no one with any clout actually cares if this thing gets built (not like they will use it, and most of the wealthy donors/voters they care about likely won't either), no rush as long as they have something to point to showing they are doing 'something'

Eventually, when the money runs low, make up a sob story blaming someone else for it, and go back to step 1.

When someone actually cares, we still build things quickly - the Oroville dam fixes, replacing the I80 overpass when the tanker truck burned it down, etc.

The problem is less that we can't build big things - it's that most of the time, we don't actually NEED to (in a real, existential way) - at least in the opinion of those with actual power.

My experience with Azlo is pretty subpar. Their Stripe/Square/PayPal integration is pretty ridiculous. As a Fintech startup, I expected free invoicing with ACH instead of just providing a buggy interface and subpar integration with existing services. Also, they violated a bunch of regulations opening my business account, which means, they may have done it with others, which can wipe them out of business pretty soon.

I never really got webDAV to work properly but I gave it a good go. Today I would never think to use it, I am more of an sshfs type of guy and rsync is my friend.

However, what does disappoint me is how things like DropBox and WeTransfer took over with some marketing that just had instant appeal to people. I prefer to have my own 'sovereign' server space and if anyone wants to send me stuff then I want it on the server, not on my desktop. It doesn't matter who it is, but if I give them a network drive of sorts, they can have webDAV, FTP if they insist, ownCloud if they want it, SFTP and all these methods to put whatever the files are on the server. They can even understand that the files need to be on the server and not on my local computer, but no, I get some email about a weTransfer link.

With ADSL the download is fine but upload is that bit slower. So you have to do the WeTransfer type of thing and wait for that, then upload the file to the server. It is never me that really wants the file on the server in the first place, it is always them.

Anyway, I think webDAV died as a thing not due to the flakiness of the implementation but more to do with why it is that people use website builders like Squarespace, why people prefer cPanel instead of some standard issue OS, why people prefer whatever is marketed to them as 'easy' rather than what takes two minutes of critical thought to learn.
>Is that true?

Depends. Some places just like it, but a lot of it is to shoo loiterers away.

>eg if I'm going to the mall to buy a shirt, I'm not really interested in how many "loiterers" are in the store browsing, I just want to go in and buy a shirt.

You're not thinking like a status conscious retailer. Some retailers prefer to not have people of certain races be seen associated with their brands. Their target market will be disinclined from shopping there.

Also, in many cases loiterers actually just intimidate people.

It's actually fairly annoying for subtitles, but it's useful for getting videos in unfamiliar languages to the right ballpark. Afterwards, my go-to so far has been to just perform a manual one-off adjustment in VLC after the video starts (you can offset subtitles in increments / decrements of 50ms with hotkeys h and j).

With spectre/meltdown mitigations increasing the cost of syscalls I imagine this becomes quite significant.

Somewhat orthogonally, does anyone happen to know if the hardware fixes eliminating the need for software mitigations still increase syscall cost substantially? I imagine if you have to inhibit speculation across context boundaries the cost is still higher than a pre-spectre world, even if done in hardware...

> That is not the solution. Usernames are not passwords. If they were, why have them at all?

Claiming that usernames cannot be a source of entropy/security needs foundation.

Back when the whole concept of authentication was new (UNIX) that was true because usernames were quite literally public information, you could see them via a directory listing. With early email (SMTP) that remained true but worse via public directories listings across-computer.

However in this context there's nothing inherent about a username that allows us to ignore its security characteristics. Unless the argument is "over the shoulder" leakage? Which I'd argue itself doesn't have a strong foundation.

Both obscure usernames and obscure passwords can contribute to the overall strength of a system. A system that allows the user to set their own password may gain particularly from pre-selected randomized usernames, as users have proved untrustworthy in the past when picking passwords (e.g. reuse, patterns, common words, etc).

As an aside, scrapping usernames and only having a password isn't inherently problematic, except two users with the same password may clash, and a password recovery scheme may be more difficult to develop. That's essentially what authentication tokens are.

> Generate a random unique password for your user and don’t have a username at all.

Because having an unknown username with an unknown password increases the difficulty of compromise via improved entropy.
I just replaced my wife's failing 2013 MBP; meanwhile, my 2009 MBP with "real" parts (I upgraded the RAM, swapped out the battery, and replaced the HDD with an SSD), is chugging along quite happily, validating my hatred of the move from replaceable, common components to integrated parts for the argument of "thinness."
Tanning beds are banned in some countries with high skin cancer rates for good reason. It is a lottery and you are accumulating risk with exposure. I strongly suspect (without any real evidence) that there are a number of beneficial health effects to moderate UV exposure that can improve quality of life for some people but the experience with fair skinned populations in high UV parts of the world has been overwhelmingly negative. The public health advice is basically written in blood on this topic and so I would view people and sites promoting alternative views with an appropriate amount of skepticism for now.
That's a really big question, I think the simplest way to answer is to say, "(Mostly)Let animals be themselves, kill them quickly".

With regard to cows which I know the most about that means letting them eat grass and only providing input when necessary to protect the health of the herd from an unexpected insult, e.g. unexpected drought, or to promote the health of the land. Because I've not tried this on a nationwide scale I can't guarantee that it could be done, but based on the thought I've given to it and my own experience I believe the majority of beef production _could_ be done humanely with the caveat that it would likely be unprofitable to do so given our current economic and cultural landscape.

I don't think dairy can be done humanely at scale for our current consumer price point.
Thank you! I'd wondered about that. I'm on the fence about whether it's worth sticking with old Apple hardware if going that route -- if you're going to hackintosh, maybe current spec'd hardware is a better target? -- but there's a case that it's less likely to have problems (and perhaps an ethical case regarding respect for Apple's licensing rights).
the fourier series was one of the things that blew my mind. any periodic function can be decomposed into a bunch of sine waves! even (the interesting portions of) many other functions can be approximated by a (potentially infinite) series of sine waves! it's simply madness i tell you.
its a two-edged sword. if you can trust the application code to effectively schedule itself then it's good but you can also get bugs and perf issues where a synchronous chunk of code blocks progress on everything (see js blocking the main thread and causing the ui to freeze)

the pro is that your async code explicitly defines points where context switching is okay since you're blocking on something anyways. this could be good for perf if context switching in the middle of a synchronous operation is expensive.

the con is that your async code might not cede control often enough to allow other coroutines to make progress.

so yes, you can have something hogging the runtime but in the context of an application that you control as a whole this is something you can avoid/fix if necessary.

at the OS level this might not make sense because you have to assume that applications are adversarial and will try to hog cpu time...
