I have no issues with BTRFS, apart from the documentation is really poor.

I don't mind it becoming popular, but please for the love of $Deity can we please make the docs as good as ZFS. I will contribute cash if needs be.

Facebook are utterly shit at documenting things, so yes it might work for their usecase, but they essentially store knowledge through Shamanism, which is terrible unless you're inducted into the world of the spirits.

Overall good, surely better than London, but there is a spectrum: the cheapest shops there aren't good, and the best ones aren't the most cheap.
Exactly. I can't imagine that the Scandinavian model ever working somewhere like in the US. I say this as a native Scandinavian.

I think a more appropriate comparison is with Canada, whose system is also flawed in my opinion (I don't like the Scandinavian model either because it doesn't work anymore nor does it scale.)
We as a family run a bunch of Synology NASes and back-up to each other (with different households we get geographical distribution). Running Synology-provided apps Drive (syncing and backing up computers to NAS), Hyperbackup (backing up from one NAS to another) and Moments (takes care of photos from cellphones) has been very simple and does everything we need.

All that just for few hundreds of euros; all data are private and nobody is trying to constantly upsell or trying to figure out how to monetize something taken for granted until now.
Simplification, a lot of reduction in bureocracy and fraud investigation... since everyone applies by default. More freedom for the individuals since their benefits are no longer tied to having to jump through hoops or demonstrate how incapable they are...
Not everyone has the latest and greatest gaming PC; I know people that can afford it, but they play games that are 2-5 years old they can buy discounted ($20 instead of launch price of $60) and the average computer of the day can play with max settings. Living on UBI does not make people stupid, just lower budgeted and even encourages making some better decisions - having more sense than money.
Do we really need to entertain throwaway accounts created just for the boring "lang {good,bad}!" interjection?

If you want to see it, there are so many places we have that discussion. And that discussion can be found so many times online. Look at any Go version release on HN if you want to find more.

Even making a top-level comment like "Can anyone explain some quick pros/cons of $lang?" would go farther than these interjections where we need to prod them with twenty questions just to help them flesh out their own point of view. That's what's annoying about it.
education is not a scarce goods - why not accept _all_ candidates that are good enough? The cost of educating one more student is marginal, and if there's a large enough number, economies of scale can kick in as well.
Which means the productive members of the society will be paying even more taxes, just to feed off people that think living of the UBI is good enough for them, if the UBI is not funded through the printing of the money.

How is that fair to working people with ambitions?
To be fair, sliced bread replicated really well.
Do you actually use zsh? C-o and M-q and M-a and M-h and all the others are really nice, and as far as I know bash has nothing similar (correct me if I'm wrong). You don't NEED any of these niceties but they're very nice.
Selecting randomly from a cohort already judged good enough is a meritocracy. Perhaps you prefer the French model with a linear ranking nationwide and a cap on how many thousands down from the top can go to the ecole normale superieur?
Yeah, I can understand wanting the downloader to exist outside of the game (so they can update a broken game out-of-band) - that's all reasonable.

The issue is, as you say, a single-threaded "download-extract-next" flow... It's 2020 and that's what we'd expect from a 90s game launcher. Steam and other game launchers/downloaders can all saturate an arbitrarily fast network connection. Heck, even Windows Update (BITS?) can do this well. A shame Asobo wasn't able to leverage any of this.

The amount of GPU is indeed strange - I think there's more than meets the eye here. There seems to be a lot of HTML/JS type stuff in the UI here, and I wonder if they are doing some kind of GPU-based full-screen rendered surface, rather than just having a simple oldskool Windows Forms app that does the downloading without GPU acceleration.
Not really confusing when you assume the intention is to look clever - the more different the letterform you find while it still being recognisable as the one you are replacing, the more exaggerated your effect is without further reducing readability.

(Yes, I know this isn't "just to try look clever", ala 1337-speak, and is trying to make a relevant reference to the cross audience understanding the is relevant to a cross platform executable, but the point still stands about choosing less similar but still similar enough glyphs)
There are different kinds of measurable, and the purpose of the measure is important. Measuring for the purpose of management (eg creating incentives for teachers and schools), measuring for the purpose of most academic publishing, etc. Each have their own pitfalls, and I agree with you on these.

That said... there is clearly such a thing as better and worse instruction.

Where the 2-sigma claim gets interesting is scale. We're not concerned with marginal differences (management measures) and we're not concerned with legibly identifiable causal relationships (academic publishing). We're just concerned with establishing a high watermark.

The simple measures (eg testing) we have, work fine for that... in the context of math, reading/writing, foreign language, etc. Stuff that's easy to test for, and assuming we're only interested in big differences.

Two sigma implies that within 1 year of instruction, the two sigma group will have progressed by several years. 12th grade math level by grade 10. This doesn't have to be achievable by every teacher, it just has to be achievable at the high end.. assuming a random sample of students.

Agreed though.. we have a history of insisting that the unmeasurable be measured... and its a very common, long term failure mode. more harm than good. I'm not suggesting implementing anything, let alone implementing anything using measures. Just setting that watermark, so we know what awesome looks like.
>documentation is really poor

Absolutely, the best one is at Archwiki and even that one is meeh.
Using a non-FAT filesystem for portable storage opens up lots of issues regarding broken permissions. Try to create a file on an ext4-formatted USB flash drive using your current user; rest assured that, unless your remembered to set its permissions to 777, on another computer you'll have to chmod it because it still belongs to the possibly dangling creator's UID and GIDs. If you don't have root access, and unless coincidentally your user has the same UID as your other machine, you're screwed and you have to go back grumpingly to a system where you have administrative privileges.

Same thing applies to NTFS, but I've seen that more often than not Windows creates files on removable drives with extremely open permissions, and in my experience NTFS-3G just straight ignores NTFS ACLs on the drives it mounts, so more often than not it JustWorks™ in common use cases.

I think a journaled extFAT-like filesystem would be perfect for this task, but given how hard it was for exFAT to even start to displace FAT32, even if it actually existed I wouldn't expect it to succeed any time soon.
> There are often situations where students just performed better on a standardized test because they could afford a couch or had better teachers and not because they are “smarter” or more capable

The solution is to make sure that students have good teachers and a couch (??) to become more capable, and not to waste limited elite teaching resource on less-capable students.
Please expand more on why Rust "is a better choice"?

I'm still not convinced by this statement.
Food delivery and a Pear logo? Canada is usually very good with their laws and enforcement in general. This case will not bode well for Apple, given how they're trying to generalize fruit logos as identifiable business marks, when tons of businesses, including Fruit farmers have been running things here.

I hope Apple lose, and they lose big!
Not quite. Zsh can use the subfolders to disambiguate which parent you meant, bash can't.

Magnum XT Pills for Passionate Sexual Sessions
Magnum XT is a male improvement equation, which bolsters the male to dispose of the issue identified with sex. The principle point of this enhancement is to deliver testosterone, which helps in the guideline of sexual execution. The enhancement additionally helps in expanding endurance and vitality. The enhancement helps in expanding the sexual drive inside guys. Individuals can perform intercourse forcefully and for quite a while. The enhancement decreases the evil impacts of expanding age, and it additionally improves the creation of testosterone.Click Here https://apnews.com/ceb0476c868ecb2836afb52dd3f000ed

That and additionally it has implications for the development team as well. Using "chaos engineering" shifts the mindset of the developers. As a developer you now expect things to fail. You know that the "we make it work first and make it resilient later" approach will bite you sooner then later so you think resilience from the first line of code.
If you ask for a lawyer immediately and don't say anything else, then police must prove your guilt.

However, if you allow questioning to proceed, you cannot always stop the questioning in the middle with the same rights as above.

Also, in the US, improperly obtained evidence is seldom thrown out of court for some reason. Arguing that a warrant wasn't obtained doesn't always work.
It's amazing just how many people believe that neural networks have a close resemblance to the human brain.
I learned basic algebra from an analog learning medium (a "choose your own adventure" style book) that attempted to diagnose and address misunderstandings and gaps.

I can kind of see what you're saying, but what does "annotated objects on the backend" mean. If there is not a standard I can only hack a solution together. I cannot ensure anything with 100% certainty, instead I'm left guessing if my logic is correct.

With a standard, however, I can be sure that what I intend is being validated and if my logic is wrong then I can change it to match the spec.
> If you take a look at the wealth of the average population, two thirds are either pensions or property wealth. This is longterm money which I cannot draw on until retired (and most certainly won't affect my children) and property which I might depend on and therefore not be able to turn into money.

Having to not pay rent is a form of income though.

> Also people are largely not against generational wealth, they're just demanding that rich people pay their fair share when inheriting property wealth to their children. Taxing the top 10% correctly and without fraud would bring in enough cash to support the bottom 30% a lot more through public housing, health care and childcare support.

Another way to say it is that the top 10% got there because they use their money to make more money. Countries need their money to make more money but not at the cost of society falling apart, so we probably need to reallocate the usage of that money to support a better society overall rather than to just make more money.

What would be interesting is to force rich people to invest in social efforts with their money. Instead of taxing them and taking away money from them (which is quite un-American), instead any monetary amount above X should have some percentage of it devoted to social funds or have to pay a penalty fee (which is effectively a tax) if they don't.
even better than a dictionary: use dicewords, which have already mapped numbers to a canonical list of words.

The recent claim (maybe 10 ya) was that Yakuza influence forced inspectors to sign off on foundations that were not sound. So they do not have the required pilings. I don't know how that could be fixed, but I don't assert it couldn't be. I assume if it is, it would have been done by now.
I suggest you never look under the hood of the compiler frontend ;)
> No amount of code review will stop Microsoft from adapting their version.

Way to miss the point. Code review for the kernel isn't just about verifying that the code currently works. It's also about making sure the code is maintainable. Microsoft is relevant here because their actions will increase the maintenance burden of any Linux NTFS driver. Kernel developers rightly need to be concerned about how difficult it will be to extend the NTFS driver to handle new NTFS features that Microsoft introduces.
Let's unplug them and test it before rolling it out on a large scale. We don't want to order a billion free energy machines before we know that they actually work without being plugged in.

Will tax payers in the UBI community accept their increased taxes? Will those paying taxes move out of the community, leaving only those on UBI behind (who will then not be able to fund the UBI)? Will we see an influx of unproductive citizens into the community to gain the UBI benefits?

Once that's answered, we'll have a better idea of the feasibility and requirements. If people want to avoid the increased taxes so much that they'll move, we'll know that we need to close the borders to force them to stay, for example.
Let's take it further. Colleges should be government-funded, and their level of discretionary funding should be based on how they are rated by their students and an independent assessment of their students' skills and general knowledge (to be administered before and after attending).
Ironically, a fully encrypted Linux installation with Btrfs or ZFS on a removable drive is quite easy to make and it works really well. I've one I made on an old SSD I had lying around and a 2.5" USB-C caddy and it's wonderful, you can have your work environment everywhere you want and even plug it into a running machine and boot it up using Hyper-V or KVM.
One thing I wonder (and find difficult to simulate) are failures in external services. Sure you can unit test your function with a 500 for example, but you never know in which ways the function/library can fail

(Not to mention the cases where it says everything worked but it didn't)
Even if the patent on the instruction set expired, that's only half the battle (if that). When you licence ARM you're getting both the instruction set design AND the implementation.

Agreed, although most of this will end up wrapped up into the token and system itself, I suspect.

U2F is pretty much a "key" (some even visually looking like keys) that are used pretty much like a physical key - put the key into the keyhole (USB port), and press the flashing light. Done.

That level of UX is what we all need to build towards!

I disagree that college should be a pure meritocracy. Students from disadvantaged backgrounds would have a really hard time getting into college, even though many are extremely smart and have great potential to succeed at college. Meritocracy is biased towards the privileged.
Stack ranking everyone and then taking only the top outliers is not a way for society to operate.
A few points:

- No this doesn't affect RHEL.

- It's only for Fedora Desktop spin (which for various reasons including this, but also others, you shouldn't use even on a Desktop - I install Fedora Server on my laptop).

- Only a subset of btrfs features will be used, especially avoiding the ones which are known to be problematic.
Hi!

Author of the article here.

The core concern is not about the capabilities of the compute abstraction being used (bare metal, containers or functions) or testing OS capabilities. The aim is to validate mitigations which are in place to counter turbulent scenarios (For example: massive spike in traffic, network outage, dependency is down, etc). These scenarios generally originate outside the given system.

These kind of questions should be asked and systematically validated (quoting the article):

* Have you tested how the system behaves when the underlying instances have a sustained CPU spike?

* Is the system behavior understood under different stress?

* Is there sufficient monitoring?

* Have the alarms been validated?

* Are there any countermeasures implemented? For example, is auto-scaling set up, and does it behave as expected? Are timeouts and retries appropriate?
First, you don't need savings if you have UBI forever.

Second, you ignore the basics of economics of demand and supply: if a large enough proportion of the population lies on UBI you will even find cars cheap enough for them, either second hand or purpose built. True story, Renault is a car manufacturer that sells their cars for prices very similar to everyone else, but they built for some years a model that was selling for 5000 Euro (about $6000 at that time) new, with a modern and solid engine and all the safety features mandated by law in Europe. That car was also sold in France for a lot more (8000 euro or more) just because people in France afforded to pay more. Now Renault is still selling 7000 Euro cars (Dacia Sandero) that are really good for the money, while selling Renault branded cars for around 20,000 Euro and more.
Not to mention the US government recently sent $1,200 to a huge swath of the country and Alaska has had a similarly sized UBI-like fund for years. If we want we can chop it up and give it to ourselves each month and call it a $100 UBI (somewhat means tested). Alongside smaller, more direct comparisons like this study, I think we already have a fairly good sense of what a small to moderate UBI would look like.

Nothing would go crazy. People would have more money. They’d work the same amount except select groups (students, disabled, elderly) and be slightly/moderately happier at least in the short term. We’d either have higher deficits or taxes, probably both.
> government-funded...based on...an independent assessment of their students' skills and general knowledge

This would compress the wide spectrum of American college experiences into a single state-mandated standardised test-driven program.
There's "unlimited WhatsApp, Messenger and Facebook" in data plans in some EU countries. Which is kinda nice, but probably only cements their monopoly.
Respawn point: The inevitable reincarnation of the corporate office
Wow, what a place. I sadly never had the pleasure, being a West/South-West Londoner and only really making it as far as Camden in my teens. I used to live in Marylebone and there is still a fantabulous little bookshop - as far as I know - called Archive, which deals with a lot of sheet music and retains a piano. It's a marvel. Buried in the backstreets just south of Church Street market, and just thinking about it makes me want to bike into town and give them all my money.
zsh now, What was wrong with bash?
I maintain that I would like to see UBE -- Universal Basic Employment.

If you can work, we have a job for you.

Part-time, full-time, your choice. We'll even train you up.

Especially in the US -- there is tons of work to be done on infrastructure, plenty of research to be sponsored with results placed in the public domain, etc.

We derive a large chunk of our personal value, out of what we contribute to our tribes -- our community, our friends, our company, etc. If somebody is willing to contribute to society, we should encourage and enable that.
It means nothing. This is only for the Fedora Desktop spin, and it's lead by the Fedora community not Red Hat.
That was a really long time ago...
I too have fond memories of using Ceefax for my football news pre-internet - the ones I remember were I think "302" for general football homepage or "310" for Scottish football scores.
Calculus was the worst for this: in my first class we spent literally two months dissecting the minutiae of limits and Lipschitz conditions and infinitesimals and blah blah etc, only to get the the punchline, "and you find the slope of a function by doing the obvious thing, which works in the obvious way every time you'll actually be using it in practice". I get it in a college level analysis class or something, but as an intro in high school that's just a great way to make students hate what is at its core a very simple and useful subject.
> To make the neuron network be a strong AI, we may need the parameters in scales of 10^19~10^44 (uncertainty limit and Planck time) estimated from how many frames per second in real world.

There is absolutely no basis for claiming this. It might turn out that there are better algorithms for AI than neural nets. Do you even realize just how many parameters even 10^12 is???
> Take any country with wide social safety nets. You don't really need to work in them to live.

Please give an example of such a country on Earth, it does not exist. Mythical countries don't qualify.
I get the impression that the Acorn guys had more of a hand in the consultation process for the film!
Wow. While this is quite slick (and must have been funny to implement), I actually hate this kind of "magic" behavior.
It does not matter what form that wealth has. You can sell it and convert the wealth to another form. That doesn't change the fact that if you wanted to, you could draw a sum comparable to UBI from it indefinitely - that is, for generations.
Don't worry, zfs has it's own share of problems.

I have one CentOS machine where I can't update ZFS from 0.7 to 0.8, if I want to boot again (zfs#8885).
> requires more ongoing maintenance (scrub, rebalancing)

I'm not sure that's a good description. Scrubbing is an option that you get extra. You don't need to use it and the behaviour won't be different than for example ext4 with regards to bad data detection. It's purely an extra feature.

If rebalancing is useful for desktop users (wasn't really in my experience), I'm sure it will get a system-provided job that balances the resource use and amount of reclaimed space.
> People socialize a lot less than they used to

You live in a small rural community. Industrial revolution happens, and slowly most people move to cities. If you stay in the little town, you feel lonely, "people don't visit anymore". If you move to the city and try to live by the old rules of rural community, you'll be upset: "people on the street don't say hello and good morning anymore, they don't socialize!". But they do - just by different rules, across different groups from before.

We are going through an industrial change on a level last seen 100 years ago at best (electricity, cars, factories). Life is changing accordingly.
It is for a subset of the market that only uses the web and a few apps. Otherwise, no, and Apple knows it which is why they are sticking their ARM silicon in Macs and continuing to evolve MacOS.
