[05:32:33] Gentoo/rizon !bang

[09:44:42] Gentoo/rizon Null_Anonymous, I do.

[09:45:16] Gentoo/rizon USB 2.0 isn't really what I would call a replacement to it, as such really isn't low latency or nearly as fast.

[09:45:52] Gentoo/rizon You'd be hard pressed to find one - you need to get a PCI-e to firewire adaptor really.

[09:46:08] Gentoo/rizon It's kind of a feature that USB 2.0 doesn't have DMA unlike firewire.

[09:46:18] Gentoo/rizon USB 3.0 is too proprietary for my tastes./

[09:46:55] Gentoo/rizon PCIe wasn't a thing in 1995.

[09:47:44] Gentoo/rizon Not being able to extend the features of a computer and being stuck with whatever ports and protocols that the board was manufactured with was a bit yikes.

[09:48:57] Gentoo/rizon I use firewire for my nice 482.6mm sized sound card. Too bad the BIOS is kind of buggy with the PCIe, so that needs to be fixed before it works perfectly.

[09:49:19] Gentoo/rizon Based low power consumption.

[09:50:18] Gentoo/rizon Yes, but even with a highish voltage, they didn't dump 500W into them.

[09:50:31] Gentoo/rizon At least the 486 line of CPU's operated without proprietary software/.

[09:51:15] Gentoo/rizon Yes, Intel actually complied with their secondary supplier contract back then I believe.

[09:53:14] Gentoo/rizon Eventually they refused to supply the CPU designs to AMD, so AMD decided to reverse engineer and re-implement.

[09:53:26] Gentoo/rizon Intel of course tried to sue, but they kind of lost.

[09:54:21] Gentoo/rizon The bizarre series of lawsuits continued until the current state where Intel loicenses x86 to AMD and AMD loicenses AMD64 to Intel

[09:56:27] Gentoo/rizon That would require actual fair competition, not happening.

[09:57:18] Gentoo/rizon Even if the socket is the same, the southbridge does specific things. It really shouldn't be hard to just make a decent southbridge design for once and then use it for everything - but that wouldn't allow for a socket change a year.

[09:58:22] Gentoo/rizon I remember, one of the reasons FireWire was killed was because "Apple" was too greedy and wanted $1 per firewire port per computer for a patent license. The previous contractual arrangements were that you needed to pay $50,000 into the firewire group and then you didn't need to pay anything more.

[09:59:07] Gentoo/rizon "Apple" of course broke such contract. "Intel" couldn't be bothered to make them follow the contract and so decided to go with usb.

[09:59:48] Gentoo/rizon Too bad, even 4-5 years, RAM uses a different, more complicated design.

[10:00:02] Gentoo/rizon It appears that DDR5 RAM DIMMs now run proprietary software.

[10:00:45] Gentoo/rizon Nobody has figured out libre DDR4 RAMinit, but at least the chips don't usually have a processor controlling them.

[10:01:37] Gentoo/rizon ECC should have been a standard feature of RAM since a decade ago, but every related company decided that's only for servers and overcharge accordingly.

[10:02:21] Gentoo/rizon With the density of DDR5 approaching physical limits, error checking and correction was pretty much a hard requirement.

[10:03:18] Gentoo/rizon But they didn't just implement ECC - they implemented some error checking and correction, but no way to report corrected errors or errors that couldn't be corrected. Such features are only available on more expensive ECC types.

[10:04:29] Gentoo/rizon ECC DDR3 is really the sweet spot - it's <=$20 for 8GB sticks now and there's libre DDR3 RAMinit for the KGPE-D16.

[10:06:14] Gentoo/rizon It's kind of hard to find highly clocked DDR3 ECC though - but really the speed of DDR3 is plenty adequate.

[10:08:01] Gentoo/rizon If I remember correctly, proprietary software on the RAM was one of many things preventing Raptor Computing systems from making say the Talos III for POWER10 based CPU's.

[10:09:10] Gentoo/rizon Ideally there should be none, but they do happen. ras-daemon-ctl hasn't deteced any ECC errors the last time I checked, so I'm not 100% sure ECC is working, but hopefully I'm just lucky.

[10:10:06] Gentoo/rizon Someone on the coreboot channel did say ECC works, but ehh.

[10:11:23] Gentoo/rizon It doesn't make the system slower by any meaningful amount, as the memory controller has all the checking hardware accelerated.

[10:12:25] Gentoo/rizon How else would you do it?

[10:13:53] Gentoo/rizon Buffering? Implementing ECC in software would be quite interesting.

[10:15:10] Gentoo/rizon Most server RAM is indeed buffered - in RDIMM there's a register that buffers RAM commands one cycles to keep pressure off the memory controller: https://en.wikipedia.org/wiki/Registered_memory?useskin=monobook

[10:15:56] Gentoo/rizon It adds 1 cycle in latency, but being able to add much more RAM is worth it. You can still use UDIMM on servers, but not much.

[10:18:11] Gentoo/rizon I believe the reason ECC is so rare is computer manufacturers are so stingy that they don't want to add an extra memory chip for the recovery/parity bits.

[10:19:27] Gentoo/rizon Yes, but you can make just as much, but actually deliver a decent product.

[10:21:04] Gentoo/rizon We live in a dystopia, but not the cool kind - the kind like eating noodles in the rain at Chinatown. No manufacturer will make good hardware - they always fill it up with proprietary software to the wazoo and expect you to buy a new one every year.

[10:23:12] Gentoo/rizon They shill recycling, but we really can't recycle computers. Any "recyclers" go and take the worn capacitors off the board for resale (as new of course) and then shove the boards into an acid bath to recover the precious metals. The rest goes into landfill.

[10:24:52] Gentoo/rizon I'm going to have to get a few more KGPE-D16's to last me, but for long term, it looks like the future will have to be free hardware designs running of fast FGPAs.

[10:25:43] Gentoo/rizon *on

[10:26:10] Gentoo/rizon Finally NSA btfo then.

[10:28:51] Gentoo/rizon and more importantly, freedom achieved.

[10:31:37] Gentoo/rizon But sadly, most people don't say no even once to degeneracy.

[10:32:14] Gentoo/rizon So we are far from that achievement.

[10:39:42] Gentoo/rizon yournamehere, Do you like my freedom posting?

[10:41:00] Gentoo/rizon yournamehere, Why aren't you a good chatbot? Why can you only write huh?

[11:19:37] Gentoo/rizon Hmm, I need a softer keyboard. I'm getting rms wrists.

[12:14:18] Gentoo/rizon Is it possible to die from blood loss from a list finger provided you don't intentionally keep the wound open?

[12:14:22] Gentoo/rizon *lost

[12:16:44] Gentoo/rizon Ehh, it depends how good your body is at clotting and if you run around or are sitting in water.

[12:17:03] Gentoo/rizon If you just focus on putting pressure on the wound, it will eventually clot up.

[12:19:11] Gentoo/rizon Usually the metal piece is strong enough to stab through the shitty quality material,.

[12:19:27] Gentoo/rizon Good luck if you have an actual quality belt though.
