What a great photo! What did you use?

Portia are the best spiders, hunting the worst pests.

Nothing I had as a kid ran on batteries. It was all springs.

You think I'm doing the "riding dinosaurs" spiel, but I'm not that old. And, yes, there were things that had batteries, but not most kid toys. I had a 3' tall battle robot from some TV show, pre-transformers, that shot hard little plastic missiles from one fist, and the entire other fist could be spring-launched hard enough to bruise a younger sister's forehead. Not that I'd ever have done such a thing. I had an Eagle lander from Space 1999 with detachable cockpit, which also must have been 3 or 4' long. I had fucking lawn darts, perhaps the most incredible and incredibly dangerous weapon sold as a toy, which we would try to launch over the house into a yard we couldn't see, and compete for who could get their's stuck most deeply in the earth. When I was 6, I had a full-on pump-action BB gun capable of putting holes in thin plywood.

We didn't have a lot of batteries, but we also had almost no regulation in the toy industry, and it's honestly surprising to me today that so few of the neighborhood ended up in the hospital from just the toys.

It's a sad commentary on our times when a body can't even roast sausages in their own back yard, and they have to sneak out in the woods to do it. SMH

I like this idea, but with the increase in supply chain attacks, I'm reluctant to use it. I've been much more reticent about installing from AUR, and my use of github projects has drastically slowed down since I now feel as if I have to read all the source code for everything I get.

I've sandboxed programs before, and I may just start making that standard practice, but still... it makes me angry. It's, like: this is why we can't have nice things. There are precious few OSS supply chain static code analysis tools, and there are a lot of languages I don't know well enough to review, or which have such broad or deep dependency trees that it's more work than it's worth. The most frustrating is the dampening effect it's having on OSS. It only pushes people to only use programs from big commercial companies.

Anyway, none of that is directly related to your program, which is really cool. Sadly, if there aren't any positive developments in the OSS ecosystem for attacking the supply chain problem, cool projects like this are not going into my toolbox.

Why do you say that?

We got a glimpse of what a true exodus could look like, and I'm with you. As much as I'd love to see Reddit collapse from its own shittiness, for Lemmy's sake I'd rather see a trickle who have a chance to learn manners and leave their vitriol behind.

Not saying Lemmy's perfect. I'm not saying I'm perfect: I have bad days and make asshole responses, too. But they get swallowed, or I get a reasonable response and I apologize. In the main, the real, consistent excuses for human beings who resist the opportunity to become better people tend to join instances like Hexbear, and can be blocked en mass.

TBH what I saw first is that you connected a fan to some hard drives and called it a homelab.

It was pretty funny for the half second it lasted.

I liked the idea until you made it about sound.

I don't want some random kid biting me. I could get rabies.

Huh. I don't really hear any units of length anymore, now that I think about it. Even the doctor measures my height in inches, not feet+inches.

I honestly don't know. I don't hear "meters" used at all, but the first thing that comes to mind about "yards" is the 2000 movie The Whole Nine Yards.

US football still uses yards, doesn't it? I don't watch football either. But I just checked a random football stats website, and it still uses yards to measure pro football stats, so... yes, I guess. A lot of Americans still uses "yards."

Meter was easiest for me because it's essentially a yard (when eyeballing).

Liters are easy because the soft drink industry picked up on it decades ago as a way to get people to drink more soda. You'd buy cans and 6-packs, but nobody bought a gallon of soda. But they would, it turns out, buy a liter of soda, and as we got more obese as a nation, 2 liters. Liters of consumer drinks are really common, and so easy to visualize.

Rockets are: put a bunch of flammables in a giant tube and light it on fire. That's my understanding. Well, Ok. I know there are nozzles on gimbals, but... here's a joke that represents what I'm talking about:

A brain surgeon goes to a party, and the host is introducing him to people.
Host: "John, this is Jack. He's a software engineer."
John: "Oh, that's nice, but it isn't brain surgery."
Host: "This is Mary; she worked in industrial inorganic chemistry."
John: "Oh that's nice, but it isn't brain surgery."
Host (annoyed): "Maude, this is John. He's a brain surgeon."
Maude: "Oh, that's nice, but it isn't rocket science."

I think the big picture is deceptively simple. The practice of getting into orbit is far, far more complicated.

As for airplanes, yeah. I understand them well enough; I think with the right equipment and practice I could build something that flies. It's just, sometimes seeing a behemoth in the air it's just a bit astonishing, and unintuitive.

See‽ It's a glitch in the matrix. They added the feature, but failed to work it out in advance and coded themselves into a corner.

I think what happened is that they spent all the budget up front, really nailing stuff like Physics and Evolution, and then came to a crunch and Management said, "just throw something in there! We'll polish it later," only it's so self contradicting, they can't.

The idea is that blkdiscard will tell the SSD's own controller to zero out everything

Just to be clear, blkdiscard alone does not zero out anything; it just marks blocks as empty. --secure tells compatible drives to additionally wipe the blocks; -z actually zeros out the contents in the blocks like dd does. The difference is that - without the secure or z options - the data is still in the cells.

always encrypt all of your storage

Yes! Although, I don't think hindsight is helpful for OP.

Hm? Both bspwm and herbstluftwm have tabbed layouts. It's been so long since I've used i3, but it has them too, right? Sway's a mostly config-compatible, mostly client compatible i3 clone for Wayland, so I'd expect it to have tabs, too. As well as floating windows, which every tabbing WM I've used also supports.

I think I missed your point. What are you saying? Did I say something that made you think I thought tiling WMs could only do tiling?

What I'm opinionated about is configuration files. Technically, even a desktop could be configuration-less, although I've never seen one. I have become insistent that my WM have no configuration that isn't set through a client call. Sway still uses a config file like i3; mostly the same config file, unless it's drifted significantly. That was Sway's whole killer feature: i3 users could switch from X11 to Wayland with only minor configuration file changes.

I don't know the Gaggia, but on my Micro Casa I take the head group apart every few years and clean it. A surprising amount of buildup clogs the head. Can you take that apart and get the screen out to clean it?

It's part of the recommended regular maintenance in the instructions of my machine. I've not noticed any build up since I've been using a puck screen. I still have to take the thing apart to grease it every couple of years, but the group head has been much more clean.

If you do get it apart and cleaned, and it does help, and you're not using a puck screen, I recommend getting one to help keep the head clean. They're cheap.

Yeah. This fantastic woman married me. I have no idea why.

Also, I really don't understand rockets at more than a superficial level, but I saw one launch once.

I'm quite uncertain about jet airplanes, especially when you're, like, driving in the same direction and there's a strong headwind, and it almost looks like you're going faster than them? They're just hanging there, god knows how many tons of metal and 300 people. It's creepy.

And I really think economics is proof that we're in the Matrix, because the more I think about it, the less (functional, not ethical) sense capitalism makes, and everybody who talks like they know about it just sounds like stringing together a bunch of buzzwords. Also, there's that truism that if you ask four economists a question, you'll get five opinions. Plus nobody can reliably predict the stock market; weather - a highly chaotic system - is more predictable than the stock market. It's like the programmers put it in, but when it got to the point where they had to make it explainable, they couldn't without introducing recursive conflicting rules, so it's just hand-waving, and people pretending or misleading themselves that they know how it all works.

Sorry, it wasn't the Arch wiki. It was this page.

I hate using Stack Exchange as a source of truth, but the Arch wiki references this discussion which points out that not all SSDs support "Deterministic read ZEROs after TRIM", meaning a pure blkdiscard is not guaranteed to clear data (unless the device is advertised with that feature), leaving it available for forensics. Which means having to use --secure, which is (also) not supported by all devices, which means having to use -z, which the previous source claims is equivalent to dd if=/dev/zero.

So the SSD is hiding extra, inaccessible, cells. How does blkdiscard help? Either the blocks are accessible, or they aren't. How are you getting a the hidden cells with blkdiscard? The paper you referenced does not mention blkdiscard directly as that's a Linux-specific command, but other references imply or state it's just calling TRIM. That same paper, in a footnote below section 3.3, claims TRIM adds no reliable data security.

It looks like - especially from that security paper - that the cells are inaccessible and not reliably clearable by any mechanism. blkdiscard then adds no security over dd, and I'd be interested to see whether, with -z, it's any faster than dd since it perforce would have to write zeros to all blocks just the same, rather than just marking them "discarded".

I feel that, unless you know the SDD supports secure trim, or you always use -z, dd is safer, since blkdiscard can give you a false sense of security, and TRIM adds no assurances about wiping those hidden cells.

Ever see Minority Report?

That, but without the psychics. Insurance companies use things called actuary tables to estimate risk. If they have your DNA, they could decide that, since you have markers for early onset Alzheimer's, they're going to charge you double for life insurance.

Law Enforcement could decide that, since you share some trait with other common criminals, you're more likely to do crime, and get warrants to surveil you more closely. Maybe you don't do crime, but you get pulled in for a crime in the neighborhood because you're the one with the highest crime DNA score, and that's enough to convict you. Maybe you get pulled over more often for going a little over the speed limit, because you're being watched more closely. Maybe they just decide you're so likely to do a crime, they imprison you proactively.

None of this is absurd; it's all been done before. The Nazis used to evaluate people by how big their skulls were - this is Eugenics on fucking steroids, backed by the smell of legitimacy because DNA. People have wrongly gone to prison and served entire sentences because of bad DNA testing, and it's still used.

This should worry you. It's not hypothetical, it's not a conspiracy theory - the potential for abuse of a database like this should concern everyone, liberal or conservative.

Like all those white supremicists who discovered they have black ancestors; only, now, all their little KKK friends know, too!

It doesn't. This is targeted at application builders. Could be an honest mistake; could be astroturfing.

You're right, good catch. Now I'm going to have to go see how it's set up; I thought it was being done in btrfs.
