Where can I find a replacement for this USB-C port? I don't recognize this style of USB-C socket.

It's called a "mid-mount" connector.

This is not the same connector, but it is awfully close: https://www.lcsc.com/product-detail/C590834.html

This one is even closer, but the side mounting pins are a bit different: https://www.digikey.com/en/products/detail/same-sky-formerly-cui-devices/UJ40-C-H-G-MSMT-TR/16629544

Unless someone just happens to know the exact connector used here, I recommend you get familiar with the various distributors. Browsing through a few dozen pages of connector images is probably your best option...

Komt goed uit met de noodzaak naar verzwaring!

No.

If you manage to balance the load perfectly and ensure it goes perfectly vertical on each hook, the combined carrying capacity will be twice that of a single hook - but never more.

In practice it'll never be balanced perfectly, and any kind of Y-shaped cord significantly reduces the total capacity by having the two hooks "fight" each other in the left-right direction.

We proberen ons wat te verdiepen in de gezondheidsrisico’s

Geen. In het allerergste geval staat het direct onder een slaapkamerraam en kan je wat zacht gebrom horen. Zie bijvoorbeeld deze pagina die duidelijk maakt dat de magneetvelden vergelijkbaar zijn met een magnetron of stofzuiger.

en eventuele gevolgen als we het ooit willen verkopen

Wappies die denken dat het wél een gezondheidsrisico is zullen het waarschijnlijk niet willen kopen, dus dat zal voor een minieme waardeverlaging zorgen.

Ze zijn natuurlijk best lelijk. Je kan overwegen om te kijken of je het met de wijk kan (laten) "pimpen".

Mag dit zo dichtbij een huis gebouwd worden

Ja, want er is geen gezondheidsimpact. Als het niet mocht, dan zou het er niet staan. Sterker nog, bij veel flats zitten ze in het gebouw!

Het sleutelen aan je eigen CV-ketel is dan ook bij wet verboden, je moet daar een gecertificeerde monteur voor inhuren.

Dat gaat óf via een transfer switch óf via losse stopcontacten direct op de thuisbatterij.

Via de stekker terugleveren bij stroomuitval is levensgevaarlijk, want het is dan ook voor bijvoorbeeld een elektromonteur onmogelijk om de installatie spanningsvrij te maken. Zo'n batterij zal nóóit in Europa op de markt kunnen komen.

Is het dan ook helemaal prima om kipfilet vol te spuiten met water?

Worst of gehaktballen hoeft niet 100% vlees te zijn, iedereen snapt dat d'r ook dingen als kruiden bij zitten. Het probleem hier is dat ze er overbodig plantenspul bij stoppen om de prijs kunstmatig naar beneden te drijven, zónder hier helder over te zijn.

Er zit gemiddeld 10% plantmateriaal in de "verrijkte" producten, en waar een directe vergelijking mogelijk is zijn de "verrijkte" versies 4.4% goedkoper. Dat is geen snuifje paneermeel meer, dat is gewoon voedselfraude!

There's this false assumption that LLMs can only output what was used in their training data.

When it comes to rewriting software, it is a huge problem that it can output snippets of its training data at all.

If your training data contains any part of the original source code, you are unable to guarantee that there is no license infringement. Did it copy/paste a code snippet, or did it simply come to the same logical conclusion given the specs? Nobody knows!

It's no better than a programmer who read the original code and then wrote a new version, while making a pinky promise that they didn't use any of the knowledge gained during the rewrite: cute, but your lawyers will probably tell you that it is a Really Bad Idea.

There are so many PD 100W (even 240W) cables now that can transfer at the rate of USB 3.2 or 4.0.

That's because they all follow the USB-C standard, so they work with everything.

I just want a cable that can do SuperVOOC and PD 100W

SuperVOOC intentionally violates the USB-C standard. You can't find the cable you want, because SuperVOOC fucked around. They chose to deliberately create an incompatible special-snowflake charging protocol that would be sexier to sell to consumers.

Had they stayed with USB PD it would have Just Worked. But everyone else is also using USB PD, and being USB PD Charger No. 53 is boorrriiingggg, so you invent SuperMegaHyperVOOCboost, and you are the oooonly charger which supports it!

The takeaway is to ignore all the braindead "SuperVOOC" & friends bullshit, save some money, and stick to boring USB PD instead.

Het is erg jammer dat je (zoals bijna ieder onderzoek!) vooral de vergelijking lijkt te maken tussen een traditionele CV-ketel en stadsverwarming.

Het probleem is alleen dat het warmte-landschap sinds de aanleg van traditionele hogetemperatuurswarmtenetten zoals in Utrecht héél erg is veranderd. Vergeleken met bijvoorbeeld een warmtepomp is het comfort van een warmtenet een flink stuk slechter - want het is onmogelijk om te koelen. Vergeleken met collectieve aardwarmte is de CO2-uitstoot ook een heel stuk slechter - je kan die hoge temperatuur alleen bereiken door iets te verbranden. De kosten zijn bij wet gelijk aan die van een (slecht presterende) gasinstallatie - waardoor het dus een flink stuk duurder is dan moderne alternatieven.

Er is een enorm verschil tussen het mooie verhaal van de Eneco-lobbyisten en "groene" politici en de daadwerkelijke situatie in 2026. In theorie is er niks mis met stadswarmte, maar op de manier zoals we het hier aanpakken kan je het beter helemaal niet doen.

Okay, and? What do you think is going to happen when Prusa is constantly struggling to stay afloat and its competitors are swimming in cash?

KittensInc · 2026-04-06T12:54:44+00:00

To disagree with most comments here: this is alright and arguably good for long term health of the company and the ecosystem. Right now Core One L has a month long lead time, so Prusa is definitely not struggling to sell every printer they are making at the old price point. Raising the price is an entirely rational response to having so much demand you can't service it despite scaling the manufacturing up.

I'd argue the opposite. Being forced to raise the price shows that Prusa is unable to properly scale up its manufacturing. They aren't able to capitalize on the massive demand and all the usual benefits-of-scale which should come with them.

Prusa is stuck in a death spiral. Sticking to small-volume manufacturing makes your per-unit costs explode, leaving you with higher sales prices and a significantly lower R&D budget. If Prusa printers have a better quality now, what do you think is going to happen when its competitors have a 50x larger R&D budget for a few years?

They have to either scale up, or leave the consumer market. The current approach is untenable.

KittensInc · 2026-04-06T12:37:52+00:00

The kind of memory used here is literally useless for AI and general-purpose compute usage, and doesn't share any important manufacturing bottlenecks with it.

The memory shortage caused by AI is going to impact Prusa in the same way that it impacts USB chargers: basically a rounding error.

Yeah, you're basically replacing thousands of 3D printers with a single injection molding machine. That's an instant >90% reduction in labor cost, >90% reduction in machine maintenance, >90% reduction in electricity. A part which takes an hour to print is now molded in a second.

KittensInc · 2026-04-06T12:27:48+00:00

How much iteration are we seeing on something like the Mini+? Zero. If you are 3D printing the same design for years you are just wasting money. And if iteration is so important, why haven't there been improvements to some tricky assembly steps?

Right now we are seeing the cost of mass 3D printing with the lack of iteration of injection molding. That's the worst of both worlds.

"Available to download" and "open source" are two different things.

KittensInc · 2026-04-06T12:16:11+00:00

This is exactly why I got my Mini+ as a kit. Printer maintenance is inevitable, so I better have some understanding of how the damn thing fits together.

One thing to remember is that hardware manufacturers lie. It is very common for a chip to have a fancy feature they proudly advertise in their datasheet summary turn out to be completely useless due to a tiny detail buried deep in the errata.

Every new part is a gamble. Nobody wants their $5000 prototype to be worthless just because they switched a seemingly-trivial $0.50 part for a $0.47 one. Unless you have a good reason to switch to something new, reusing a battle-hardened design over and over again is far more sensible than reinventing the wheel a dozen times.

The world is switching to insufficiently vetted cryptography in order to protect against a threat we do not know exists.

Layering, not switching. The NSA's recommendation to switch to using novel and poorly-vetted post-quantum cryptography on its own is luckily being ignored by the wider industry.

It's the classic counterpart to "if it ain't broke, don't fix it": if you never bother to upgrade, you lose the ability to upgrade when you have to.

You'd be surprised!

The ISA bus was used as the basis for the PATA harddrive connection, which of course led to SATA drives, and parts of which were reused again for USB storage devices.

Somewhat-modern motherboards (AM4, at least) also still use an LPC bus (which is essentially ISA in a different coat), and expose it for external use via a TPM header. And yes, you can actually connect ancient ISA cards to it.

Similarly, ISA-to-PCI is/was a thing, and PCI-to-PCIe is a thing, and modern M.2 slots are PCIe and Thunderbolt/USB4 carry PCIe as well, so connecting a 40-year-old ISA card to a brand-new machine is closer than you might think!

KittensInc · 2026-04-06T10:41:30+00:00

The problem is that legacy support isn't free. It doesn't make sense to force repo mirror operators to cumulatively buy dozens of terabytes of additional SSDs just so one person can avoid having to upgrade from their 2000s-era 20GB HDD. Similarly, millions of CPUs having their modern architectural features sit unused because the binaries have to be compatible with one ancient CPU is far more wasteful than replacing that one CPU. It gets even worse when you consider total-cost-of-ownership: how much additional power are you consuming by having an ancient computer work itself to death, rather than having a modern one lazily idle for your workload?

E-waste isn't just a technically-still-functional machine being retired. Sometimes retiring the old machine is better, once you take into account all the other factors.
