Had to do some work with SuSE post Novell acquisition for a customer. IIRC the package manager is a bit odd, but I haven’t looked at it in what nearly 15 years, so I can’t really remember much about it. What I CAN remember involved running packet traces using Wireshark - it was mostly network problems, I think, so nothing to do with SuSE. It was certainly very popular in Europe, though I have no idea what they’re doing these days!

You never know … maybe THIS year!

The way windoze 11 is going - people really hating it - you never know, but I’m not holding my breath. Linux is still very niche, and people are wary of “strange” “new” things, especially FREE ones - where’s the catch? I’ve seen it surge and blossom over the years, but it’s still got a really tiny install base (as long as you don’t count Android and embedded tech, where the OS and kernel are largely irrelevant to the user). But I don’t see people moving over to Linux in droves any time soon, really: I’ve seen too much.

For context, I’ve been using it since [dredges up old memories] slackware was new, so about 1994, when a work colleague and I installed it (off about 20 floppies) onto an old 386sx PC with probably 4MB of RAM. Been using it ever since - and from Red Hat 4 onwards (about 1999) it’s been my only OS on my own computers. I’ve always preferred it, and I’ve seen it grow in so many ways - I’d still use it if it was illegal. I haven’t tried EVERY distro, but I have tried most. These days I mostly stick with Debian or Debian-based distro’s (I’m currently on Mint LMDE).

He’s bang on. LLMs have no understanding of anything: they are literally just statistical models.

Don’t have any experience with this particular model, but I have found that with most printers on Mint you don’t have to “do” anything at all - if it’s on the network or plugged into the USB, the system will find it and install a driver automatically. I’ve used MANY printers with Linux over the years, and some were a right PITA to set up, but so far all the printers I’ve tried with mint have “just worked”. The only problem I’ve had recently was that when I updated to the Debian Trixie based LMDE 7, a bug in CUPS misconfigures EPSON ET2860 when automatically discovered, but it still works on stock Mint 22.3 without manual intervention. The fix is to manually add it, rather than accepting the auto discovered one, so it’s a problem with the discovery function, not drivers, and I suspect it’s due to some kind of quirk with this printer’s firmware that defines how it interacts to discovery queries on the local LAN.

Thanks. Context helps.

Not only can you take loans against your shares, but you can pay the interest on those loans with dividends from the shares, and because they’re a loans, the cash-in-hand is not taxable, so you pay NO TAX on it. You have no “income” on paper, but you can pay people and companies with shares instead of money, shares that you can literally conjure into existence by typing numbers into a spreadsheet. Those money and shares are really useful for greasing the palms of politicians, government officials, and hangers-on so that you can get your way. You can even use this money and influence to cause riots and stoke division in society.

Mandatory where?

Yeah it was wild, but I suspect few orgs do things that way any more.

Salmon reversing aid.

You mean in the context of high availability?

tl;dr: It’s to test if the cluster fail-over configuration is working properly.

So this was before things like Kubernetes or Terraform were a thing, so had to be done by the operating system itself. The simplest HA cluster is made of two nodes, one in “active node”, the other “passive”. The active node does all the work, and the passive node just keeps its data synchronised with the active node. I used to use DRBD for this, which is a system for copying writes to the active node over a network link to the passive node. That only gives you a “second, up-to-date copy” which is not that useful on its own - you also need a way to automatically switch over to using the passive node if the active one “dies”, and for that I used to use “heartbeat”, which simply passes packets back and forth between the two cluster members - ping-pong style - and if the passive node notices that the active node hasn’t sent its scheduled packet for, say, 10 seconds, it cuts it off the current active node (kills it), and promotes itself to the active role, thus preserving the service. Killing the “other node” is necessary to stop data corruption or user requests going to a node that can’t actually service them, and is called STONITH - Shoot The Other Node In The Head. STONITH can involve an electronically controlled switch, which literally cuts off power to the “other” node, or can isolate it on the network, by shutting down its network ports on the switch, or in a VM setup, sending a notification to the hypervisor to kill the VM.

The reason you need to be able to kill the kernel on the active node, is that when you manually shut down the active node, it automatically informs the passive node that it’s going down, known as an “orderly fail-over”, and you’re not actually testing if the heartbeat fail-over works, you’re just testing an orderly fail-over. Killing the active node’s kernel tests that the passive node is properly configured to take over during a catastrophic failure of the active node. You can watch the heartbeat status go from “up” to “down”, and then see the passive node decide to take over, promote itself and bring up its services, and begin processing requests.

To make sure it’s all working, you need to test orderly fail-overs first, from both nodes, then test disorderly fail-overs both ways, by using the kernel gun on the active node.

Things moved on from Heartbeat-based HA clusters to multimode clusters managed by Corosync and other software, enabling other strategies to be employed. This was eventually supplanted by “orchestration” systems like Kubernetes, and proprietary Virtual Cloud systems that move this functionality to the platform rather than the operating system.

Nah man. “kill” doesn’t shut the system down quickly. This is the “instant death” way - the kernel reset gun - no shutdown scripts, no disk sync, just reset to BIOS boot sequence, instantly:

As root:

echo 1 > /proc/sys/kernel/sysrq

echo b > /proc/sysrq-trigger

If you change out the “b” in the second command for “o” it will just halt the kernel instead of rebooting. Still switched on, but the system is doing absolutely nothing.

I used to use this trick all the time to test high availability server clusters.

Sounds great, look forward to seeing that. After using it a bit more, another thing occurred to me - there’s no way to open arbitrary files. I don’t use MarkDown for “just notes” or “just one thing”, I keep markdown files all over the place. I had set the repository directory to be that of my blog posts during first run, but then I can’t open things in my notes directory or documents folder, and I can’t see anywhere in the settings dialogue to change it. Am I missing something?

Yeah “but not as annoying” lol. No idea what you mean about jeeps: I’m in the UK, and not a car enthusiast either.

Seems quite good - I’ve tried a LOT of MarkDown editors over the years, but until quite recently, I’d stuck with Zettlr for a long time. I’ve recently reinstalled my laptop, which made me look for alternatives to some software, and I’ve been playing round with MarkText for the last few days, which seems nice.

HelixNotes is definitely good - if I had to drop MarkText, I think I could get on well with it. I like that they have a debian repository, so I can keep it updated with the usual system update software. I downloaded the AppImage as a quick test, but it didn’t work because it was compiled against an old version of glibc.

The only thing I don’t like so far is the format toolbar is at the bottom of the editor screen, and I haven’t found a way to move it.

You’re quite right, Ozone is actually O₃, I got that wrong. I should have looked it up, but I didn’t, hence the error. I’m so sorry I mislead you - can you forgive me? Ozone is actually very interesting - did you know there is a layer of the upper atmosphere known as The Ozone Layer, and that it has a hole in it? Also, Ozone is sometimes produced by chemical reactions and electrical arcs - it has a distinctive, Ozoney smell. As you also made mistakes, I think we are now even - have you ever considered taking up a career as a Large Language Model?

What about Microsoft Bob? Doesn’t that count as their first attempt?

Just wait until LLMs are used to design most of them - they will be distinctively average.

I usually do that too, but this time round I’ve really not had the spoons. Had the “Red Letter” yesterday - “we’re sending in the heavies”. I still CBA - send 'em. We don’t have a telly and we don’t watch any telly via the web - we HATE TV. I don’t even watch any U-tubers regularly. Been this way for >20 years.

This diagram is wrong on so many levels. Ozone is “charged Oxygen” (O1 rather than the usual O2) so it’s saying you get Ozone out of the Hydrogen side. The bubbles are forming in a place where they can’t get to the output vents, so the accumulating gases would slowly force the water level in the inner chamber down, and thus up through the vents. It’s pretty shit. Is it AI slop?

NPM is not a Linux thing - it’s to do with web applications, so it works on Windoze and Mac too.
