> 2) There are a lot of local and global symmetries in physics -- i wonder what new capabilities adding them to a CNN would enable?

It would be trivial to make any ML model satisfy dimensional homogeneity. Just use only dimensionless variables consistent with the Buckingham Pi theorem. Other symmetries would probably have to be baked in from the start.

As I recall some engineers are developing ML-like models that satisfy all sorts of physical constraints under the name "model order reduction".
Getting Real: smarter, faster, easier way to build a successful web application
Well if you assume a full automonous car is as safe a driver (on average) as a 16 year old male that liability you are worried about can be (will be legislatively required to be?) insured away for a few hundred dollars a month.

The insurance market for lawnmower liability admittedly isn't as well developed.
I had this experience too, my video card was so shitty that I wasn't able to watch 700mb divx videos in windows, I had to boot into linux and use mplayer.

Holy shit. I may be really dumb to fall for the marketing, but ... holy shit. This is some incredibly exciting stuff. I'm not a fan of the company, but I will always be grateful to Google for funding this kind of stuff. Usually, one would expect research department of Universities to do stuff like this. I'm glad that Google Research is allowing all these really smart scientists to build all this stuff. Spellbinding.
They seem to already be incentivized sufficiently, though.
The problem with FUSE file systems is not that they aren't part of the kernel's VCS repo, but that it requires a context switch to user-space.

I enjoy the regular reminiscing of BeOS, but for all the talk about how fast it was on hardware common at the time, I wonder why nobody remembers an even more impressive "tech demo" of an OS from that same period - QNX 6 desktop? An ISO of evaluation edition of 6.2 was easily downloadable for a while, and it was pretty neat:

https://guidebookgallery.org/screenshots/qnx621

(I know that QNX was and still is widely used - the "tech demo" bit refers to its use as a primary desktop OS, not the usual embedding scenarios.)
I don't blame Linus, but I use ZFS a lot.

I'll drop ZFS the moment I have an alternative with the same features:

- disk management with simple commands that can create raids in any modern configuration

- zero cost snapshots

- import/export (zfs send/recv)

- COW and other data integrity niceties

- compression, encryption, dedup, checksums

I am very grateful to the OpenZFS community, and I think they deserve praises for their work. Saying the code is not maintained is quite unfair.
That works for mass transport like bus, tram, metro. For individual transport, it doesn't make much sense, any more than it would make sense to rent a car 24/7/365.

It would work better for individual transport if there was balanced multidirectional flow around the clock. Instead we have mostly-unidirectional flow centered around narrow times of day.

> There are no (stable) alternatives. BTRFS certainly not, as it's "under heavy development"¹ (since... forever).

Note that they don't mean "it's unstable," just "there are significant improvements between versions." Most importantly:

> The filesystem disk format is stable; this means it is not expected to change unless there are very strong reasons to do so. If there is a format change, filesystems which implement the previous disk format will continue to be mountable and usable by newer kernels.

...and only _new features_ are expected to stabilise:

> As with all software, newly added features may need a few releases to stabilize.

So overall, at least as far as their own claims go, this is not "heavy development" as in "don't use."
Which state? Oregon has an assisted suicide law but it doesn't cover dementia. I'd love to hear about which ones do as I also formed this plan after seeing my father go through it.
Glacier or no, it's a beautiful piece of nearly pristine land. I imagine they'd simply find other attractions (there are several possibilities) or focus on the hows and whys of the glacier's disappearance.

If you haven't, I recommend visiting. If you can't visit, have a look at some of the pictures taken by those who have.
I’d argue the opposite.

The problem with your position is that you are already describing the status quo of our society - virtually every entrenched interest in our society already gains from climate change denial. Fossil fuel exploitation industries and transportation are a trillion dollar industry already.

On the other hand, the other side of the scale has nothing. A billion dollars in a hedge fund won’t be the tipping point when Exxon already has a market cap
of 300 billion.
Work Meeting Trends to Avoid: The “Update” Meeting
They harass universities about it too. Which is ludicrous, because universities often have residence halls, and people who live there often download VirtualBox extensions.
What is your email address and phone number?
That's definitely a concern. The growing modern understanding is maybe that you cannot have consent in a power imbalance, and sometimes a lot of the "code" work right now is as much finding and signaling possible power imbalances as much or more than establishing even a broad consent signal. Consider pronoun signaling as one first example where it may also signal an unobvious power imbalance (though not necessarily in every case; part of the normalization work behind pronoun signaling is that if everyone does it, for many people it signals a status quo/no change in power dynamics).

Though also an interesting counter-note to me is that the handkerchief code itself was commonly used in BDSM cases intended to signal the consensual creation of a power imbalance and asymmetry, and it is in (mixed gender) BDSM communities where I've heard most of the less publicly documented, but possibly more generally useful, successors to handkerchief code can be found. So asymmetric power structures have always been intertwined in the opt-in signaling, even if yes some of the early symmetry was probably a necessary bootstrap state.
The PDF takes the point of view that it is caused by various forms of cognitive bias. I generally agree with that.

The reason that I don't think it's totally ethically neutral is that it is a basic responsibility of scientists to be on guard against cognitive biases to the best of their ability. It's possibly even the main feature that separates science from non-science.

Cognitive biases can become ethically bad particularly when they intersect with a person's personal interests. For example, if an investigator thinks "I won't be able to publish this result as easily if it diverges too much from the historical values, so I'll just run this experiment again", this is a problem. Even if it occurs totally subconsciously, it is a breach of duty because the scientist should take great care to avoid this kind of thing.

It could be viewed as Bayesian updating, yes. But my main point is that it greatly complicates the process of literature review and knowing how much certainty to assign to a scientific finding. If there are 10 papers saying X, but each one is highly dependent on the last, there is much less evidence for X than there appears to be, particularly to an outsider looking in.
Front and Center
I mean, he's right. VFS, VMM, and buffer cache are all three sides of the same coin. Nearly every system that puts the FS in user space has abysmal performance; the one exception I can think of off the top of my head is XOK's native FS which is very very very different than traditional filesystems at every layer in the stack, and has abysmal performance again once two processes are accessing the same files.
> every simple, effective drug gets blacklisted pretty quickly, because... [they don't make people] dependent on our horrifically broken medical system

This is a claim that demands substantial support - particularly when simple effective drugs are used routinely! - and you've offered none.
Not to be overly antagonistic here, but "the process" doesn't work at all. Doctors make drive-by appointments, write an Rx after a few minutes, and they don't want to hear any guff about it. Many of them refuse to take action that would benefit their patients because they're worried about drawing attention from law enforcement or getting labeled as a pill mill. High-deductible health plans are becoming pervasive so each check-up is a hundred bucks. Patients are treated alternately like cattle or criminals, must adhere to the doctor's schedule ("sorry, I only work half-days 3 days of the week, and make sure you schedule 4 months in advance!"), and the doctor has forgotten everything about the patient by the next follow-up. These are the people to whom you're entrusting your brain chemistry.

Meanwhile, the industry replaces pseudophedrine with phenylephrine (placebo whose only reliable effect is increased blood pressure) so that they don't have to admit every effective decongestant is now restricted and pushes the predominantly-ineffective atomoxetine as a replacement for amphetamines.

There are definite benefits to competent medical supervision, if it ever actually happened, but it's so uncommon that we're better off dropping the pretense and just using drugs that work.
> This being "Oracle," and its litigious nature, how can you truly be aware or sure?

The functionality I'm describing has absolutely nothing to do with ZFS or Oracle in any way. If you really think the reach of Oracle is so great, then why not block all Oracle code from ever running on the OS? That seems to me to be just as justified as this change.
Makes sense, I thought there would have to be some "good" reason.

Your wouldn't need anything much more powerful than a Pi4B to do that part for a couple of cams, but I guess this keeps the cost down for a security-unconscious public.
My home NAS runs btrfs in RAID 5. The key is to use software RAID / LVM to present a single block device to btrfs. That way you never use btrfs's screwed-up RAID 5/6 implementation.
Okay, let's get the full quote:

"A 90-year-old woman lived independently, despite a history of stroke, congestive heart failure, emphysema, osteoporosis and hypothyroidism. After a fall in her residence during the winter, she presented to the emergency department of her local hospital where she was given long-acting morphine orally to control pain in her chest wall. With a diagnosis of pneumonia and renal failure, the patient was transferred to a ward, where the morphine was discontinued and hydromorphone was ordered in its place. Unfortunately, the patient received both analgesics. Two days after admission to the ward, she was found unrousable. Narcotic overdose was considered. After a single bolus dose of naloxone intravenously, the patient became alert; however, left alone for a few minutes, she was then found without vital signs. No further attempt at resuscitation was attempted because a do-not-resuscitate order had been previously entered in her chart at her request."

It isn't a simple case of an otherwise healthy person not given narcan because of a DNR. They were very ill, injured, and coded after an inital nalaxone treatment. Honestly, if it were me, I might want to shake the hand of the person that gave accidental overdose. Regardless, that is great link and both cases are very ethically complicated.

You should look into it more yourself, but for example, one might want to withdraw life sustaining treatment (food/water) if they are in a persistent vegetative state for a certain period of time. Based on other circumstances they might want a hard DNR. It is important and people should educate themselves about end of live decisions and options.

edit: I just realized you were referring to case #2. That is also complicated ethically.
Availability. I probably want to use a car the same time as everyone else. Price. If there's enough cars to satisfy demand at all times, the capital costs of the network are high which means rates are high.

Basically, a large operation could have economies of scale (in house mechanics, only two models of car to choose from, own the fuel stations...) but the utilization of the vehicles probably would not change dramatically from the utilization of the private "fleet" we have today.
I don't think BTRFS has ever been considered stable.

I think they just said: "The on-disk data structure is stable" and lots of people misinterpreted that as "the whole thing is stable"

A stable on-disk data structure just means it's been frozen and can't be changed in non-backwards compatible ways. It says nothing about code quality, feature completeness or if the frozen data structure was any good.
It's not the context switch that kills you for the most part, but the nature of the API and it's lack of direct access to the buffer cache and VMM layer. Making a stable FKSE leads to the same issues.

That's why Windows moved WSL2 to being a kernel running on hyper-v rather than in kernel. Their IFS (installable filesystem driver) stack screws up where the buffer cache manager is, and it was pretty much impossible to change. At that point, the real apples to apples comparison left NT lacking. Running a full kernel in another VM ended up being faster because of this.
Very simple, have you ever rode a scooter? Once I took a ride along the beach in Southern California, it was immediately obvious, and, I was hooked! It's a disruptive, perfect combination of technologies, that immediately antiquates riding a bike for short distances. The main problem is that it's too good, and people with poor balance, poor judgement, or bad luck, have been in accidents which ruined it for everyone else.

I could see scooters completely wiping out local ride-share, taxi, and bicycle shares in many places.

But again, people have been injured and because of that, along with the excessive inventory that has littered some areas, cities are cracking down and writing new regulation to curb their use. In the short term they will win and we might not enjoy their full potential for awhile.
This is the first I’ve heard of them but they seem to be based in DC and have government clients. I’m guessing they are funded by the US government to acquire vulnerabilities to use against targets as well as defend from being sold to other countries first.
The police already attracts the corrupt and power hungry. This is just how security services work and why their power needs to be checked and there has to be oversight.
Better than the other article by far.
Looks like really cool and useful project. Is it usable on Windows though?
I can't press Shift key to enter ":" for commands. Seems like a dealbreaker. I tested it on WSL and Ubuntu on VM and Shift works there.

Anyway. This look super cool. I'm a Windows guy but have been using terminal more lately with tools like https://github.com/BurntSushi/ripgrep https://github.com/sharkdp/bat https://github.com/sharkdp/fd and they work great on Windows (plus are easily installable by https://scoop.sh/). Hope the Windows story will improve for Broot to.

Some suggestions after very quick look (except not working Shift key on Windows).

* Screen refreshing and general experience is really slow. Hold arrow key for couple of seconds and see that refreshing can't catch up. The best performance is on standard windows cmd, a bit worse on new "Windows Terminal (Preview)", absolutely horrible on ConEmu (which I use daily :-( )

* I sort of expected that I can "scroll" current directory but I get "400 unlisted" text at the bottom. It makes sense for nested directories and looks like main feature of Broot. But for _current directory_ it would be great if it didn't "trim" entries at the end and you could just use standard arrows keys, PageUp/PageDown and Home/End to quickly glance and see what files are available when I don't know what file names I'm looking for. And when I would want to do the same for some nested directory I would just select it with Enter.
So basically it would be great if Broot was more like https://github.com/junegunn/fzf but not just for flat list of files.
Boeing, as the manufacturer of the 737 has a vested interest in covering up any shortcomings (and any costly compensation) with a faulty aircraft.

Any country who would hand over the black box to the aircraft's manufacturer without previously copying of the information held on that black box would be criminally stupid.
Sort of. But no snapshots.

Wanna use LVM for snapshots? 33% performance hit for the entire LV per snapshot, by implementation.

ZFS? ~1% hit. I've never been able to see any difference at the workloads I run, whereas with LVM it was pervasive and inescapable.

A National Geographic piece on Glacier National Park. You can see some "before" and "after" pictures of the last hundred-ish years in the first minute of the 3.5 minute video.

Are they gone? No. Are they going? Sure looks like it.

I recommend visiting (in the summer), regardless of the glacier status. It's beautiful.

Security from malicious programs or exploits, accidentally altering system files and other device users.

We used to be able to trust intentionally installed programs not to exfiltrate data. It's sad that we still can't.
> ZFS hasn't kept up with SSDs.

Pretty sure this is false. ZFS does support trim (FreeBSD had trim support for quite a while, but ZoL has it now as well), as well as supporting l2arc and zil/slog on ssd.

> ZFS partitions are also almost impossible to resize

You can grow zfs partitions just fine (and even online expand). You just can't shrink them.
> negative externalities

This is very true. macOS and the iPhone, for me, went from being "obviously the very best of the best" to "the lesser of all evils".

When my 2015 rMBP finally gives up the ghost and / or when 10.13 loses compatibility with the applications I use, I have no idea what I'm going to do - probably buy another working 2015 rMBP used and pray that the Linux drivers are livable by then.

I know it's ridiculous, but it helps me fall asleep at night sometimes.
Since this tracks the combined size of the top 100 npm packages, my guess is that those spikes are caused by packages entering and leaving the list.
There are also lots of conflicting studies like this: https://www.ncbi.nlm.nih.gov/m/pubmed/26248567/
That guess is likely wrong.

More likely, is that whomever set this department up, has a background in managing call centers, and they've just re-implemented all the same penny-pinching, degrading practices.
Sure it is. Quiesce your application, take a snapshot, then resume application. Then you can back up the snapshot. The alternative can be a lengthy downtime for your application.
Regarding the mandatory taxes, I think you're talking about "green neighborhood" district taxes that supposedly help to deal with quality of life issues.
Nothing wrong with modularizing code or pulling in complicated things as a dependencies. Rewriting the same tools a million times isn't a great world either. The only thing I avoid/take issue with is pulling huge dependencies to use only a tiny part. Like I wouldn't base anything designed like this page in my projects, it pulls in 1 MB of React to dynamically display an image that updates once a day.
Have fun building anything remotely complex.

These kind of "Absence of evidence is not evidence of absence" arguments in social-justice topics constitute a Kafka-esque trap from which the accused cannot argue their case any further in a reasonable manner.
I agree that it is not entirely self explaining. I ended going with Diagram as Code based on the Infrastructure as Code [1] principle which is the same concept; you write code to generate your infrastructure.

You're making their point.

You're saying it protects against "inept" attackers, that lowers risk.

No need to nitpick a simple analogy.

Do you have single-thread cpb benchmark figures on amd64 hardware without AVX512?

Clearly the benefits of AVX512 really exaggerate the comparison on hardware that supports it, and the benefit over Blake2S is pretty muted on hardware without vector intrinsics (low end 32-bit ARM). But I'm interested in the middle — e.g., Zen1/2 AMD, Broadwell and earlier Intel x86-64.

Thanks!
It runs on circle CI (look at the .circleci folder). Half the logic is in there, the other half in ./size. I am on mobile so I cannot check the methodology, but it seems like the CI is committing the stats back to the repo
I mean, it doesn't really work that way, you can't just port a userspace program into a kernel module. For starters, there's no libc in the kernel - what do you do when you want to call `malloc`? ;)

With that, I doubt the performance issues are directly because it runs in userspace, they're likely due to the marshaling/transferring from the in-kernel APIs into the FUSE API (And the complexity that comes with talking to userspace for something like a filesystem), as well as the fact that the FUSE program has to call back into the kernel via the syscall interface. Both of those things are not easily fixable - FKSE would still effectively be using the FUSE APIs, and syscalls don't translate directly into callable kernel functions (and definitely not the ones you should be using).
> because nobody is more than a modest constant times more productive than anyone else,

Having met people causing net negative productivity, this is pretty hard to believe. Why do you expect this to be true?
Firstly, congrats on an interesting project with clearly a lot of thought and time investment. At end of article you request feedback on should you open source - in that respect:

There is clearly some interest in this area e.g. DS-PITON project (See https://bit.ly/35Eq35R) or the Jive project for java (https://cse.buffalo.edu/jive/). Another would be Glamours Toolkit for Pharo Smalltalk (https://gtoolkit.com/) - though it has a larger scope.

If you do not have time or funds to continue it in its current form and you do not have any 3rd party at this point interested in sponsoring development in some form, and you cannot see how to leverage it in the future - what do you have to lose by open sourcing it?

At worst - it languishes, and no one uses it but it will give you a referenceable open source project for your CV that may help attract work in this or a related area.

At best, the project sees adoption and opens new opportunities for you.

Given the quality on display in the articles and videos I would expect the project to get some interest especially amongst IDE and program visualization communities.

If you do decide to open source the project be careful on licensing choice (to encourage adoption in a manner you want) and copyright notices to ensure you are associated with it. Do expect to have to invest a little time in documentation and code clean up before making it available - but think of that as future advertising for your own capabilities.

Good luck
