It's a hard pill to swallow, adding two more drives in a vdev to get one more drive worth of storage (authors case maxes out at 6 drives, currently has 4). So often you will bite the bullet and just completely rebuild.

True RAIDz expansion is something that's supposed to be coming, possibly in Q3 2022, so it may be that by the time one needs to expand a volume, that ability will have landed. That'll be a game changer.
> Germany only uses that for interviews on the news

Yeah UK news is the same - someone speaking over the original audio which is audible but played at a lower volume. At the risk of introducing yet another tangent here, there's a funny twist to this. A few decades back the UK bizarrely had rules that Gerry Adams' (leader of Sinn Fein) voice could not be used on media broadcasts[0]. So you'd see footage of him with another guy's voice dubbed over it[1]. This was even parodied in comedy news show The Day Today[2] to great effect :D

Get LSI 2000 or 3000 series SATA cards. Several manufacturers make them approximately to the reference spec. The drivers are in the Linux kernel. If they don't come flashed to the IT spec firmware (no RAID capabilities), do that, but the cheap ones usually do. The 4i models sometimes come with ordinary individual SATA connectors; the 8i will have one of two kinds of combo connectors that can accept cables that go to a backplace or breakout cables to ordinary SATA connectors.

There you go.
Some good links have been posted. I'll post another, but it's just the first link I saw for what it is I think you should learn first: the Distributive, Associative, and Commutative Laws. They're taught in middle school, and easy to get. But you need to get them _deeply_. Spend hours internalizing them. Play around in a spreadsheet, making 2 or 3 formulas at a time that all do the same calculation but look different because you distributed, associated, and commuted the cell addresses differently in the formulas. Learn them so well you might forget the names but you can't forget the concepts, ever. Make them part of your being. https://www.mathsisfun.com/associative-commutative-distribut...
How is the Dutch government censoring rt.com?
This was not a problem when connecting from the United States a month ago. I cleared HSTS settings for the rt.com domain but when connecting to the HTTP (not the HTTPS) site, I am redirected to an HTTPS version of the page which immediately leads to an HTTPS certificate error.

Interesting, https://sputniknews.com/ is redirected to an ISP hosted web page which reads: Deze website is geblokkeerd
Europese sancties
De Raad van Europa heeft besloten dat de websites van RT (voorheen Russia Today) en Sputnik News niet meer mogen worden doorgegeven. De website die je probeert te bezoeken, valt onder deze Europese sanctie.

VodafoneZiggo is verplicht de sanctie uit te voeren en heeft de website geblokkeerd.

rt.com is a different story. I truly don't comprehend what is happening here.

Is the Dutch government redirecting HTTP requests to rt.com with a MITM proxy to a virtual site with an invalid HTTPS configuration? The certificate is downright bizzare:

> So the options left are halogen

I don't think they are as bad as CFL. CFL have really cold dim light with some other phenomena going on. I have seen LEDs that are, though.

> but now it seems they are finally good enough to replace incandescents.

Certainly not on average. Half the time I encounter an LED I notice that it flickers, even without a dimmer. I just bought 4 for $50 thinking I paid enough to get a non-bullshit product, and they flicker and I will have to go try the $60 one next.

Ask HN: Why not give real names as rewards for passing levels in a game?
For example, you might choose real names of people who have accomplished something great (e.g., wrote a free app that you like).

After passing a level in the game, the player would see the name of such a person.

I suspect many players will want to google the name to find out who this person is and what he/she accomplished.

Maybe the people mentioned in the game will want to check it out and mention it to their friends, thus making the game more popular?
The problem of these concepts for me is that foreigners can come in while playing by other rules. Ends up pushing people out.
> I chose raidz1. With only a handful of disks, the odds of two drives failing simultaneously is fairly low.

Only if you buy different hard drives or at least from different production batches. I had a lot of trouble on the same premise and I won't make that mistake again.

Edit: He mentioned it though ( a bit later in the article)

> The problem is that disks aren’t statistically independent. If one disk fails, its neighbor has a substantially higher risk of dying. This is especially true if the disks are the same model, from the same manufacturing batch, and processed the same workloads. Given this, I did what I could to reduce the risk of concurrent disk failures.

> I chose two different models of disk from two different manufacturers. To reduce the chances of getting disks from the same manufacturing batch, I bought them from different vendors. I can’t say how much this matters, but it didn’t increase costs significantly, so why not?
The ikea setup might be worth a shot with the networking bridge they have to control multiple bulbs at once, but my experience with individual bulbs was bad.
There is a fine line dividing stability and stagnation.

For example, the Poles are much better at building apartments and transport infrastructure fast than anyone else on your list, including Germany.
I've gone the TrueNAS route, but I'm running it on a QNAP TS-451. I'm running TrueNAS off of a USB stick hanging off the back, so I didn't have do to anything with the hardware and reverting back to QTS is just a matter of setting the boot order in the BIOS.

I really like seeing other people's builds, but I know that building my own computer isn't something I want to do. I was happy to see the comparison between the DIY model and the roughly-equivalent commercial units. I'll likely buy another QNAP (to run TrueNAS on) when the time comes, and the comparison tells me that I won't get screwed too badly by doing so.
You prepare by making sure all your bases are covered. In my daily work discussions, for example, I tend to be very hand-wavy about concurrency, calling everything “locks” and hoping people understand that I can dig down into the details when needed. When I’m interviewing I don’t want to just hope, so I review my concurrency primitives to try and make sure I won’t put my foot in my mouth.
Personally, I am firmly in the "superdeterminism" camp. To me it's the most elegant interpretation of QM without any mystical measurements magically dependent on "consciousness" and whole universes created on each interaction. If you want to learn basics about it, I recommend watching this video: https://www.youtube.com/watch?v=dEaecUuEqfc Do not mind the (joking) clickbait title, the talk itself is quite good even if you only vaguely remember QM.
Sanity checks like this can be defeated by having all of the options (ABCD...) be similar enough and plausible to anyone who didn't actually study the material.
I guess this means Bellwether (from the Watch Dogs series) is real, at least in some form.

Kids cheating seems to be an universal behavior, it happens in very different educational systems (US, Europe, Eastern Europe).

I remember when I was a student, cheating didn't seem that much of a crime, to me, or to my peers. We mostly understood that if you cheat you might (or not) have problems later because you just basically wasted time in that course. So it was an assumed risk.

It feels to me that the fight against cheating is basically fighting against (kids) human nature.

Also, snitching on cheaters was unthinkable. And not because of retaliation, but it just felt like very scummy behavior. In a way, like how criminal law in most places doesn't require family members to snitch on other family members who committed a crime.

It's not hiding something, it's showing popular content more often. The intent wasn't to limit discussions to politics.
Think locality of news. Do I need to know what's happening in New York or my current city? While my current city isn't big and thus "not as popular" decisions made locally can have a larger impact on me.

That's disappointing. I don't have any stats, but I imagine 90% of beginners writing an interpreter (much less a compiler) start a lexer and parser and quit before getting to the good stuff.

Skipping the tedium until you've got "hello world" and "factorial working" makes sense to me. You can always go fix the syntax later.

Exactly. If everything I hear about requires a plane ticket I miss all the cool things in a 60 minute drive.
Actually, i wanted to ask this question to good software engineers.

I once had a coding problem interview where a half of the logic could be handled by an autobalncing tree. I\ve never really used autobalancing trees in real software before, but i knew how to make them from scratch, quickly as RB tree is a very common school problem. I spend twenty minutes choosing between coding one from scratch and picking an already existing solution. I ended up choosing gnl's RB trees, with all the makefile/autoinstall issue that i would have to fix instead. I did not gain any time, really, but i wanted to show i did not suffer the NIH syndrome. Was that a mistake? Should i stay within the stdlib during coding interviews (i don't know if they could run the code, i think the interviewer was running windows)
" I hope he spends the rest of his life being forced to use the software he made."

Haha. We all hope that. Unfortunstely in 99% of the cases, people will not use the software they developed.
Why do i have to click 5 times to save a bookmark in a web browser ? Because the developer does not use this feature. Why are all fonts in Windows either too small or too big ? Scaling does not.work.
I hear this kind of discussion mentioned, particularly in the lead-up to the Brexit referendum. I don't think it accurately reflects the status of contemporary discourse. The UK media is more right-leaning than right:
- https://www.pewresearch.org/global/fact-sheet/news-media-and...
- https://yougov.co.uk/topics/politics/articles-reports/2017/0...

I've personally noticed a tone shift since the referendum towards stronger conservative views in the Telegraph and Times. This doesn't seem to be borne out in polling, but I wonder whether that is because the entire political discourse has shifted:
- https://yougov.co.uk/topics/politics/trackers/is-the-daily-t...

Because the media are fairly non-central (particularly the right-leaning media), it's not very easy to find compromise. The stances taking by e.g. the Telegraph on transgender rights is fairly non-subtle. I don't think the rights of immigrants qualifies as a discussion where "it's just politics" applies. Since the referendum, the very core rights and institutions at the heart of the UK have been damaged and eroded, and that makes for conflict.

I think the context of with whom one is discussing really matters, and online for the most part, there is a strong in-group/out-group identity that makes it very hard to have reasonable discussions that don't dissolve into flame wars.

In person, I agree that it's good to be open minded and discuss things with people whose views you might usually not align with.

Indirectly related is the Paradox of Tolerance: that tolerance without limit is eventually destroyed by the intolerant.
"CephFS supports asynchronous replication of snapshots to a remote CephFS file system via cephfs-mirror tool. Snapshots are synchronized by mirroring snapshot data followed by creating a snapshot with the same name (for a given directory on the remote file system) as the snapshot being synchronized." ( https://docs.ceph.com/en/latest/dev/cephfs-mirroring/ )

We found ZFS led to maintenance issues, but it was probably unrelated to the filesystem per say. i.e. culling a rack storage node is easier than fiddling with degraded raids.
Even self-driving coaches will have congestion issues. Even if there are dedicated travel lanes and all vehicles are connected, capacity will (probably) at most double (going down much further as speeds increase, since a safe braking distance is still needed).

In that mode, the new techniques that are getting developed in rail signalling (ETCS level 3 moving block) might be transferred in some way, but capacity is still very much limited.

If E-Coaches are shared, you'll have difficulties getting them to you at the point & time you want to travel (probably requiring at least ~15-30 min prior information in non-urban environments, where congestion doesn't limit adoption). They'll also have to drive in-and-out of multiple residential areas (if shared), which will increase travel time.

I think self-driving cars (personal use)[1], autonomous electric busses (with many of the limitations as current busses, but lower cost & higher comfort as well as more flexible (smaller) capacity options) and rail transit will cover most demands, with on-demand transportation covering the night hours and uncommon travel routes.

Some transit agencies are experimenting with services like ViaVan (providing most of the features of self-driving electric coaches, excluding the self-driving part) and adoption seems to be low, mostly working as a complement if no other attractive transit options exist, not as a displacement.

[1]: I fear that this will be primary form of transportation, since costs aren't going to be much higher than current cars (or perhaps even lower). The possibility of doing something other than driving will make congestion more palatable and searching for a parking spot will probably not require a human on-board. There will still be a personal space owned by someone and stuff can be (permanently) left inside the car.
Productivity is correlated with display size, and VR should be the next step in productivity, because it allows your whole space to become a display and an interface. When paired with powerful hardware and innovative software it should be the next step in computing.

Therefore, VR should be a replacement for large displays in productive work, not a device that everyone is wearing outside or casually watching videos with. The use cases are professional; such as programming, CAD, design etc. I believe that properly implemented VR would allow utilizing full visual-spatial capabilities of our brains, totally eliminating the process of hunting for files and switching windows.

It would be possible to dive into code and see it all at once like an intricate factory. Our brains are capable of navigating very complex environments, but this capability is lost when its viewed through a small window.

I wish they'd explore this area, rather than go for a mass market appeal. What kind of software is possible, and how much productivity can be increased with maxed out hardware with high resolution VR? I'm not sure if 4K resolution with a M2 chip is powerful enough for a truly innovative product. Maybe it is, but there's still room for a "pro" product.

I don't think there's a use case for glasses-type product, with a watch-like functionality and environmental AR which would show information pop-ups everywhere. We already have information overload, and we don't need any more of that.
Beautifully put.

A shared illusion of mutually entangled observers with different subjective perceptions of the world with mutual lowest common denominators (senses).

The superdeterminism is the thing bugging me most about Sabine's content, that even though it's usually good, it's all from a hard deterministic perspective, which in the end is like any narrow worldview - limited in its usefulness. And superdeterminism at this point is just a philosophical version of saying "no you are" in an argument or "works on my machine" to the QA.

they allow very good professors to give real mindfuck exam questions that cause you to walk away from the test with a new perspective on the material

I think the problem with this is, although cool, very few professors are capable of doing this well and very few students benefit from it. IOW, it doesn't scale.

To my mind, oral finals or 'discussions" would repair the cheating issues quite well. But again, it's hard to scale and professors would need to be trained in how to do them.
In every Scrum team I’ve personally worked on (admittedly not a huge sample size), it was OK for a senior engineer to say that their work for the next two weeks isn’t scrum-able so they’re going to mark themselves as having no capacity this sprint.
How to Self Study Technical Things

I occasionally look at the PCIe-to-SATA market and find it confusing. It appears polarized into either cards from a reputable brand and very expensive, even with few SATA ports, or cards from an unknown brand and relatively affordable. What's your experience with this and what can you recommend (2-port or 4-port)? Are the cheap cards safe & reliable or are they to be avoided?
Time for me is by far the limiting factor. Short of a personal chef (too expensive) all the quick options are unhealthy.

Edit:

Loads of people suggesting cooking - I know how to cook, I just don’t have the time or energy. It’s not just preparation time but also the planning aspect.

Meal prep delivery services suggestions are interesting. I have tried a few and found them expensive and low quality. Open to trying more though.

Sunday meal prep: I did this as a student but I love food and I love deciding what to eat on the day. Going back to that would remove some of the joy from life.

I think what I really want is a work canteen, but open to the public. The economies of scale could make this price competitive and there’s less delivery overhead than the meal prep subscriptions. I like the social aspect too. I would definitely pay a subscription to a canteen.

I think this is how Roman cities operated.
I would read/watch about the fitness coaches who volunteered to eat poorly and gain weight to experience what their clients went through. They were all very surprised that despite knowing how to eat and exercise well and effectively how much their willpower flagged, how difficult hunger was to address, and how much more difficult it was to lose the weight than they expected.

Calories in/calories out is simple, but not easy. People who feel hungry fail at maintaining their diets long term. We do not have less willpower or discipline than people in the 1970s, yet so many people are overweight now. Even wealthy people with serious resources remain overweight. This points to a systemic problem, not merely personal failing.
> Do coding interviews work in the actual world in which we live in?" No, fundamentally not.

I look forward to seeing you disrupt every major tech company in the world via your superior hiring strategy.

> EVEN IF THE CANDIDATE CAN IN FACT PROGRAM JUST FINE.

You don’t seem to have thought very hard about what employers are optimising for. Everyone realises that programming interviews produce lots of false negatives. Even the strongest programmers have bad days. From the employer’s point of view, that’s okay - minimizing false negatives is not the goal. The goal is minimizing false positives. Failing to hire a strong candidate carries a much lower cost than hiring someone who can’t do the job.
