  • Let's hear it, little lemmings.

  • 3h in a room with her might put you over your annual allowed radiation limit though.

  • "See you soon" feels like a curse coming from the guy at Lowe's

  • After a few years of homeownership you usually have everything for stuff around the house in the tool room.

    I'm just noticing that having a tool room sounds unusual, seeing it written down.

  • Read the Following Manual

    Jump

  • Actually, several hours of cursing and trying are an excellent substitute for up to three minutes of manpage reading.

  • IPv6 & Opnsense & Not Exposing Machine-Specific IPv6s to Corpos

    Jump

  • Well, it IS a not very reasonable take that seems to be grounded in a certain unwillingness to deal with new and unknown yet things. How do I solve address overlap in RFC1918 and various VPNs reliably without IPv6? This starts to become a problem when I think about my self hosted music server accessed through a wireguard tunnel and I'm at a friend's house. Not too outlandish problem for the crowd around here, I'd guess.

  • FFmpeg move to Forgejo

    Jump

  • Ditching a tool for another one because of where the source code is currently stored on? That sounds a little like the people's liberation army vs. the the liberation front of the people.

    I mean, you do you, but please try not to use that as an argument when discussing open source in a general audience.

    I don't think the general move over to free-er software and less silos is supported by this kind of more outlandish zealotism.

  • German gas drive fuels fears of climate backsliding

    Jump

  • Yep. There were like 15 years of half assed trying and as soon as the smallest bit off difficulty occurs, everybody just gives up. Climate protection is over, fuck the future.

  • Im an unworthy Fraud when it comes to Tech

    Jump

  • That's because the average IT auditor is a bunch of if then statements wrapped in human skin.

  • Wife: "Stop lubricating everything!"

    Jump

  • Team WD-40 here too; it’s always worked well enough

    For the first step to get old, hardened grease and dirt out of whatever you're lubricating, it's a good thing, because old grease can soak in it for a bit and soften up. But then flush with something that evaporates completely like brake cleaner and then as a third step use something like I recommended above. I love Würth HHS, it won't even fly off a motorbike chain, but other companies offer equivalent products by now.

  • I create daily timestamped files on the datastores that are involved in the backups and have a script that restores specifically those files from the backup and compares the content. If that succeeds, the backup is considered working. Its not perfect, but it's fast and automated.

  • Wife: "Stop lubricating everything!"

    Jump

  • Yes. Get a sticky oil with a thinning agent like Würth HHS - creeps into that crevice, then the thinner dries out and then that crevice will be well lubricated no matter what happens to it. And for some things like locks get a Teflon based dry lube, because those don't attract dust to moving parts. Expensive but a bottle will last years.

  • PSA: Toss a rusty air compressor

    Jump

  • Air is dangerous as well. A hydraulic system quickly loses energy on failure because oil is nearly incompressible.

    Compressed gases or liquids that are beyond their boiling point at atmospheric pressure store a lot more energy at pressure and release it a lot more violently than hydraulics when experiencing a surprise decompression.

    Let's take a 100 liter compressor tank that's buffering at 10 bar:

    For an isothermal expansion from high pressure to atmospheric pressure, the energy is:

    E = P₁V₁ ln(P₁/P₀)

    Where:

    P₁ = 10 bar = 1.0 MPa

    V₁ = 100 liters = 0.1 m³

    P₀ = 1 bar = 0.1 MPa (atmospheric pressure)

    E = (1.0 × 10⁶ Pa)(0.1 m³) ln(10)

    E = 100,000 J × 2.303 E = 230,300 J (or about 230 kJ)

    TNT releases approximately 4.6 MJ/kg of energy. 230,300 J ÷ 4,600,000 J/kg = 0.05 kg or 50 grams of TNT

    Of course a tank rupturing will expand a lot slower than TNT, but the energy is the same and when half of the tank shell points towards some offices next to the workshop, the first three walls will be impressed pretty much the same way by the suddenly very agitated piece of steel.

    Had an air tank fall over in a stupid way during refilling at our local fire station last year. Valve broke off at nearly 270 bar and the thing went off. Now there are new rules, new indents in the concrete walls and at least one fireman that reacts a bit jumpy to "clang" like sounds.

  • Installed a wall mounted weight rack today.

  • Because of the walls made from those thin pieces of wood and that gypsum cardboard sandwich and being worried about having weight hanging off that.

  • Two kinds of people. Those that have backups and those that haven't lost data yet. Or almost lost.

    Now test your restore regularly 😉

  • The other day I helped a friend furnish his new house that was next to a german equivalent for a home depot. Like, his garden fence has a gate into their parking lot. You bet I walked over there for single shims with a cup of coffee in hand and after three days the cashiers collectively grinned when I strolled in.

  • Yes, the ton of elaborate Excel macros alone that keep small and medium business running at all tells me: not going to happen.

  • Tesla's European car sales nosedive for fifth month as customers switch to Chinese EVs

    Jump

  • I'm somewhat hopeful, in the last ten years, new and renovated country roads have been getting dedicated bike lanes behind the guardrails. Miles away from the excellent, completely separate infrastructure the dutch have, but its a start.

  • Living in the boonies, I'm never going to get a bus going by every ten minutes so a solid market for good EVs is still what I root for.
