I just saw the ASUS B550M-C/CSM board show up in a search, and it's basically the best Micro-ATX AMD B550 board I've seen for any use case other than overclocking?Multiple displayports for onboard graphics. ECC support (depending on CPU). An M.2 wifi slot *and* two M.2 storage slots, both of which do NVMe and SATA. Discrete TPM (no fTPM issues in Win11…). And a Thunderbolt link connector, why not.Also it's green and has a PCI slot, two PS/2 ports, serial port, and parallel port.

Honestly the only way it could be better is if the PCB was in classic ASUS gold, and if the plastic connectors weren't all black and grey (blue and white instead?)

@null sadly no, this is designed as a desktop board rather than a server board.I'm kind of sad that the ASRock Rack and Supermicro AM4 boards with IPMI all seem to get something or another wrong, like poorly configured M.2 storage slots :/ And since they're assuming a fixed server, you lose stuff like outputs for integrated graphics or wifi capabilities that are useful in a workstation.

@null yeah. The ASRock Rack X570D4U https://www.asrockrack.com/general/productdetail.asp?Model=X570D4U looks mostly ok as a workstation - fixes the M.2 storage config weirdness that their B550 board has. But it's hard to find for sale, and expensive if you can find it.Downsides are the poor selection of outputs for APU graphics (they really don't expect you to use an APU with this board...) and no support for M.2 wifi. Also slow boot time :/There's a X570D4U-2L2T variant that adds 10gbit Ethernet, tho :)

If you want a nice relaxing April Fools video to watch, can't go wrong with This Old Tony's "Turn a CUBE on a LATHE?!" https://www.youtube.com/watch?v=PqsOgGhIsPgFrom the description:Everyone says turning a cube on the lathe is hard, but it couldn't be easier!Granted, it's an aluminum cube, but still: No sweat!Okay maybe a little sweat.

just a reminder, if you're facing a mirror, it's not flipping you left to right. it's actually flipping you front to back.

@juliobiason so, the restrictions placed on compilers are insufficient to cause the same numeric results to be generated in all cases; there's a few places where the compiler can switch around the order that operations are performed (or sometimes combine things into a multiply+add to take advantage of vector math units, etc.)And some math operations only require approximations to a given precision, and different processors or libraries are not required to be identical.

@juliobiason A fun thing back in the mid-2000s during the transition to 64-bit was that floating-point math switched from being done on the x87 fpu with 80 bit internal precision to sse2 instructions with 64 bit internal precision. This caused some numeric results to be different - even compiling the same code with the same compiler version on the same processor, just one for 32bit vs one for 64bit.

@msh @Alamantus keep in mind that GNOME 40 wasn't really a transition at all - it was just the next GNOME version after 3.38. They decided to drop the leading '3' on the version number, and that's the only thing particularly special there. It's full of all of the same types of incremental changes and updates as previous GNOME 3 releases.

@msh @Alamantus well, i guess they did take the opportunity to include a redesign of the activities overview - the switch from vertical to horizontal virtual desktops and moving the dash from the left to the bottom was kind of a big *design* change, although not that big of a difference in underlying functionality.

@wolf480pl @unascribed Youtube (as far as I know) keeps the original uploaded file stored away forever, so they can re-compress it to newer formats later if they want to.

I needed IPv6 internet access on one of my computers to test something, and my ISP currently does not provide native IPv6, and has a bug they're working out that causes IPv6 "6in4" protocol packets to be filtered out - which both prevents using an HE tunnel *and* also breaks the 6rd service that the ISP provides themselves.Anyways, I ended up using a wireguard tunnel to forward one of my digitalocean instance's ipv6 addresses to my local machine.

I also threw on a stateful firewall on the instance. Took the opportunity to learn the nftables syntax for firewall rules; I think i like it quite a bit better than iptables.

@msh It is not better than HE 6in4 in that way - seeing "normal browser traffic" coming from an IP address assigned to a server company is a pretty good way to get extra cloudflare captchas :/But that's not what it's for - having it on a VPN means i can just temporarily get *some* IPv6 connectivity for doing things like testing IPv6 connections to the conferencing software I work on; the other end of the connection is also under my control.

@textfiles @a it would be pretty hilarious if it ends up that you can just use, say, FLAC and get ok compression.

@federicomena VGA text mode is 720x400 resolution, intended to be displayed as 4:3, and I have a bunch of pre-UEFI computers that still use that mode regularly.Last time I used a Linux GUI on a screen with non-square pixels was 1280x1024 on a 4:3 CRT back in the mid 2000s.I still regularly work with standard definition NTSC video, which is almost always captured and stored in non-square-pixel formats.

@federicomena when I was using CRT monitors at 1280x1024, i made sure to configure my monitor pixel aspect ratio in my mplayer configuration so it could stretch the video to compensate, otherwise everything in the video would be a bit vertically squashed.It seemed worth it to get that extra 64px of vertical space for toolbars and things.Annoyingly most web browsers and image viewers didn't support compensating for non-square pixels.

@tek if you don't mind something that's more on the "DIY" end, the mini pc platform that the "firewall gold" is using is available barebones off aliexpress. I got one of these for my network - a passively cooled "soft router" box featuring an intel celeron n5105 processor and 4 2.5gbit Ethernet ports (6 are available too). I personally run openwrt on mine, but pfsense or opnsense are also popular options.

@tek @mike I've got 1gbps cable, and it has no problem traffic shaping that with CAKE at line speed. I have it doing some routing between Lan subnets too, and it hits the full 2.5gbps there fine.
