Deduplication and compression have traditionally been file system features not volume management features:

As fair as I know the only solution for deduplication in LVM is VDO and that was created after ZFS and isn't technically part of LVM (it's a kernel module that sits between the filesystem and LVM).

Same is true for compression except in the case of compression that's been a file system feature since the days of NTFS on NT 3.5 (released 1995) -- I can't recall when UNIX file systems first saw compression but I'd wager it was before ZFS, which we've already acknowledge predates VDO.

I also thing it makes sense that the above should be part of the file system domain because it's an integral part to how the file system organizes the data (much like how we don't argue that the journal isn't part of the file system domain).

As for checksums, they have existed in all parts of the stack, from the application level (for example rsync), to the volume level (RAID controller cards) to the file system. I wouldn't say that's something that has ever had a "traditional domain".

The things I'd say ZFS and its ilk do that isn't part of its traditional domain is RAIDing (ie management of the physical devices) and cache control. Both make a lot of sense being managed by the file system in modern file systems but I can also sympathize with those who think that's a step too far. In the case of RAIDing, you can still run ZFS on LVM or a hardware controller if you wish -- I wouldn't suggest you do so because it gives you additional complications for zero benefit but the option is still there if you want it. But with regards to cache, the only way to opt out of ZFS managing it's own cache is not to use ZFS.
Pigeon Post
The first (and only) time I ever had a CAT scan was pretty awful because they didn't tell me exactly what to do.

I walked into an urgent care because I had severe back pain. They put me through a bunch of chest x-rays where they told me to inhale and hold my breath, then they bring me over to the CAT scanner and tell me to hold my breath when the light goes green. So I inhale and hold my breath. Then the tech comes out and tells me "did you inhale? don't do that, it ruins the results".

They decided not to re-run them because the odds I had something wrong even with those symptoms were apparently less than the odds of the additional CAT scan giving me cancer down the line. Certainly didn't help my peace of mind.

But the muscle relaxants and a proper desk chair seems to clear it up within a week so I guess they were right...
I think it’s 4 million megawatts, not gigawatts. Still a small change, but not as insignificant.

There's thousands of good indie games now all over Steam and itch.io. This is approximately the first time free game toolchains are good enough to make things that are really good and not just RPGMaker stuff.

In particular I think indie horror games feel well-crafted and original now even if they're cheap. Can't tell you why though.
> These are not sanctioned, the West is buying as much as ever [...]

They sort of ended up sanctioned. You're right, there's nothing official, but no unconstrained buyer wants to touch energy exports from Russia.

Russia is struggling to sell its oil to unconstrained buyers [1]. Sure, Europe, in winter, with no ready alternative, is still buying, but that's about it it seems.

Also, while it's true global oil prices are sky-high, the rise in Russian oil is far more muted. Basically, there are many kinds of oil sold around the world (Brent, WTI, and many more). They usually move largely in lock step, as to a reasonable extent you can substitute one for another. But recently Urals is sold at a massive discount - because no one wants to touch it.

> How do you know this?

There are plenty of soft indications. Troops only given rations for 72-odd hours. Attempts at airborne strikes that are very rapid, but doomed to fail terribly with any but minimal resistance. Reports of Russia looking to "source" new troops - from Russian reserves, and Syrian, hmm, volunteers? All suggests the current length of the war exceeds plan A and plan B.

Of course Russia might still win a long, hard slog of a war, by bombing everything that moves...

This is the key insight (psychoacoustics) that led to the MP3 codec: not just converting a waveform into frequencies, but altering the result in a way that throws away most of the data yet remains indistinguishable to most listeners.
There is no QA of any kind, other then customers complaining.

Totally broken features are regularly shipped and stay broken.

A random example: Application Gateway shows 5 metrics if you open one in the Portal on the first page. Two of those metrics aggregate a rate (Mbps) using sum instead of avg.

40% of their front-and-center graphs show gibberish, and that’s been like that for probably years.

No one tested any of this. Not a security person, not a UX person, or any manager.

PS: Take a look at the cypher suites offered by App Gateway and its and TLS defaults. Note the current year. Now consider that this is their security product with Web Application Firewall functionality!

Would you trust their WAF to keep you safe? Or just tick a checkbox that some auditor says needs ticking?

> I find it hard to believe that the author started to appreciate physics by reading The Feynman Lectures on Physics before any exposure to physics

I'm a physics major. My first exposure to physics was Feynman, and it made me want to become a physicist. I think that's a statement more about Feynman than me though, as I'm not particularly talented. It was a common story among other physics majors too.

None of the fakes mentioned in your BBC link debunks anything I said. Additionally, isn't that the "western media"?

Moreover, Al Jazeera link you provided doesn't really speak to Ukraine "blocking" anything - they called Russia's move immoral, which is totally fair. It is immortal to force people to choose between running to "safety" - their invaders - or waiting for death in the war zone.

The rest of the article is just proving everything I said above, i.e.:

Billions of Mac users? All of them on this planet? /s
Yep, blaming your tools is what the incompetent do.
What "expansion of the west"? Estonia et al joined NATO of their own accord, and if sovereignty means anything then they had the right to. (You could certainly make a case about Iraq or Afghanistan, where the west did install a new government by force, but I don't think Russia has been talking about those)

> The West thinks the Ukrainian invasion is the first move of any party, and its done nothing this whole time

Hardly the first. What has "the west" done that's remotely comparable to Crimea or South Ossetia? This isn't a story of mutual escalation, it's Russia taking as much as it can get away with.
From zero a few years ago it is amazing. This is an industry that is seriously scalable.

One of my parents died recently due to cancer and I beg to disagree with your statement "It's not a disease that primarily comes from unhealthy living".

Perhaps not that scientifically savvy but this video presentation by a medical doctor does highlight the anomaly of the Middle East population that have significantly least mortality due to cancer, most probably because of their lifestyle and habit.

I honestly don't see the point of Btrfs. ZFS is more mature, more stable, better defaults, etc. The only reason Btrfs existed was because ZFS wasn't GPL. But now we have a way of running ZFS on Linux Btrfs seems utterly redundant.

I mean I'm all for choice on Linux but when it comes to file systems I'd rather have fewer choices but those choices be absolutely rock solid. Btrfs might have gotten to that stage now however it's eaten enough peoples data (including mine) over the years that I can't help wondering why people bothered to persist with using it when a better option was available.
Perhaps more importantly than being fast, it is scriptable. ("git bisect run" can take a shell command to run and interpret the exit code of, so you could script everything including the kernel recompiles and walk away for a few hours.)
The only evidence that bureaucracy is increasing that is given is … a Twitter poll?

Then, that is taken as some sort of universal law and applied to … “public discussions”? It’s really easy to measure actual bureaucracy in that field: it is none, and has always been none.

The idea that people often say it “wasn’t the content of what you said but the way you said it” just doesn’t ring true to me. But in any case, it’s a stretch to define cultural attitudes about language as “bureaucracy”. And still, if one insists on ignoring all these falsehoods, it’s entirely obvious that those unwritten rules have become far more liberal over time. My Grandparents weren’t allowed to utter a single sentence during dinner when they were children. My parents still had to stand up anytime they wanted to say something. Societies used to be stratified into distinct classes and there were specific rules on how to address members of each class, although for the category of arguing about ideas these rules sort-of collapsed for all but a tiny minority to: don’t even think about it.

You want to only talk about online speech? It didn’t exist only a few decades ago, which one might consider “the ultimate bureaucracy”. The cultural bandwidth allocated to online discussions today was occupied by the “mainstream media”, primarily newspapers. The unwritten rule you had to follow to regularly publish in a paper started with “be a man, preferably white”. That, however, didn’t get you anywhere near the power of a mid-sized Twitter account. You had to devote your life exclusively to the profession of journalism and be willing to spend years on post-secondary education before you had a chance to be hired.

Making psychedelics illegal is quite literally a crime against humanity.
I'm doing a MSc in mathematics. I tried to read that book once and I thought it was terrible. One of the few books I dropped before finishing it and also the reason why I have been reluctant to pick up other Murakami books. With respect to your phenomena of leveling up your mathematical maturity without doing mathematics, that has happened to me a few times and I would say yoga and psychadelics are the primary source of inspiration. Of course you need to do a lot of reading and studying (or if you have courses then you can sit back and have them feed it to you). One thing is making the information known and the other is to understand it, this is where the things that can spark random enlightenments come in.
Thanks for the Android app recommendation, it's amazing! Basically numi on Android, love it!
Docker performance impact might as well be zero. You're actually using the system kernel, with the application's filesystem (thus dependencies) and other resources (CPU, memory, network access) namespaced away from the rest of the system. So there is no e.g. mapping on top of the extant kernel mapping. I've not noticed and performance impact, though obviously my workflow isn't your workflow.

Seriously, try it. I personally use docker-compose, even for single containers.
No, that does not seem correct. SQL Datastores are not "map-reduce underneath", they have optimized datastructures for efficient querying (i.e. indices). Map-reduce is equivalent to those cases in SQL database where you have full table scan in your query plan - basically brute-forcing your way through the dataset.
Is the bell curve median or mean or both?
Sorry, but this is just silly.
Usually it means "nameplate capacity", the maximum the unit is rated for, not what it actually produces during a year on average.

Edit to add: if you follow the link under the figure and see the "Preliminary Monthly Electric Generator Inventory", the Excel file that opens up has nameplate capacity as one of the key columns and I wouldn't be surprised if that were the source.

Also note, when calculating the economics (cost/benefit) of power plants, they do use LCOE (leveled cost of energy) which takes into account the cost of the plant over the energy it actually will produce, which would take into account those factors. But probably this specific metric in this article doesn't.
I do love their IDEs though would point to them as being the exception not the rule.

It is still speculative but this week I did a deep dive in to the SPARC fusion reactor from Commonwealth Fusion Systems [1] and it seems extremely promising. They recently proved out their high field magnet design and got 1.8 billion dollars in additional funding, and they claim they can demonstrate net energy gain (a world's first!) by 2025. This would pave their way for a larger production plant design ARC which they currently claim they can have running by early 2030's, though of course these things can be delayed.

But the major points are that the tokamak is a well understood design. Their system uses the same physics basis as ITER, but their more powerful high temperature superconducting magnets mean they can produce a machine with the same Q gain as ITER in 1/10th the total volume. That smaller size means that they can build the machine much faster.

A few youtube videos to absorb all of this:

[2] Is their original pitch lecture from 2016, and makes a compelling argument that tokamak is well understood and simply using new high temperature superconductors allows them to design better magnets to make a small reactor work. It’s the oldest but it’s my favorite talk on the system.

[3] Is from last year so is more up to date. It is a recorded video meeting so it is kind of boring, but the subject matter is very interesting. I actually got this funny feeling like "it is the future and we are discussing fusion power plants over boring zoom meetings". Like it feels more real because it is almost boring. But a good talk.

[4] Is a good 15 minute high level overview for a general audience. If you don't want long lectures, listen to this.

[5] Is a short 4 minute video with highlights from their event last september where they demonstrated a 20 Tesla field in a large bore magnet for the first time ever.

I like the video

We’re still grasping at straws

Its nice that we have all these distinct populations to give clues to a broader solution, but there is still nothing to emulate, no rubric to follow, just a couple things to help you feel like you’re in slightly more control than you actually are

All these rates of cancer stats per capita are based on detecting the cancer, which we are notoriously bad at. It is either by happenstance or because its too late. We don't know how fast it grows, some practically overnight, some over decades. The delta changes as well. When detection methods get more personalized and better, I think the rates will go up dramatically while also providing the biggest chance at fixing and figuring out real prevention methods.
Psychedelics can be anything you want almost, not every experience is positive and some people struggle. I think a bad trip can last a really long time with people. “Not exactly what you can call recreational” my friend said to me and I agree, that’s why nobody who has done them and is a good person will recommend them as they are undoubtedly one of the most extreme things you can do.

The best advice I heard was if things are going really wrong you should change the lighting and/or move to a different location for a reset. In addition to that do it in nature with people you trust. Also probably don’t do an extremely strong microdot on your first go :-)
The VM performance hit is far too hard to recommend it for actually running applications. I'll use it to dev for another system (e.g. a Python backend for a web app) but I would not spin up a VM to e.g. compile LibreOffice or -shudder- actually run LibreOffice.
If you have the means, try printing them little by little: chapter by chapter plus any back-of-the-book material. This way you can focus on one thing at a time, tactile paper in hand, without expending money on topics you don't yet need. You can annotate it, solve problems in the margins, file it, and reserve it for reference if/when you move on to successive chapters.

> This is a thin excuse. These stories were held up as literal truths for centuries. The moral principles they embody are held up as serious until they become too unfashionable, then those are dismissed as metaphor too. If you claim a given religious lesson is good and valid today, what basis do we have for believing that someone in 40 years won't be saying that that lesson too was something that was never meant to be taken seriously?

It's not an excuse, it's reality. Your perception of religious people is outdated, ignorant, and generalizing. Should we not let any tradition modernize? Should all tradition and culture be discarded because it was once done differently at one point in time? Should we all practice life how you see fit?

> Note how you're contradicting your previous argument, because you don't have a position beyond throwing a bunch of arguments at the wall and hoping something will stick. The burden of proof is on the one making claims; otherwise we should all take Russell's teapot seriously.

A bit hostile there. No one is trying to claim anything, they are practicing their beliefs that make them feel good.

> We don't. Act accordingly.

Exactly, just be smug that you have it all figured out and let people go about their business.

Or you can keep judging something you know nothing about and generalizing billions of people.
Of course, the thing to keep in mind is that when you're trying to displace existing technology that was built to have 50 year lifetimes, this is kind of a drop in the bucket. Slowly growing, but a drop nonetheless, compared to the whole.

The generating capacity in the US is approx. 1100 GW, of which 80% is coal/NG. [1] This press release talks about this year's installed 50 GW, 60% will be renewable. And the 40% added this year is still fossil fuel, which is designed still to last 50 years.

You run into the same issues when talking about EV adoption. Yes, it's good that they make up say 10% of cars sold this year, but you're still selling 90% gasoline fleet, and it lasts 15 years and it takes a long time to displace.

The best place to have an effect is to be absolutely sure to get into the markets where they're about to start buying the old technology and help them switch to new technology as soon as possible. China/India. Getting old countries to pay to replace what they already bought is just too hard.
