    Is There a Tech Worker 'Exodus' From the San Francisco Bay Area?

    There's always lots of people leaving California, but there's usually more moving to California. I left the Bay Area because if you don't need to work at a tech company, there's better places to be (everyone has their own reasons). My wife has goats and chickens now, which wasn't going to...

    Linus Torvalds On The Importance Of ECC RAM, Calls Out Intel's "Bad Policies" Over ECC

    You only need ECC if your ram is faulty, but you only know your ram is faulty if you have ECC. It's an extra ram chip, and some more data lines. In theory, this should just raise the cost of memory modules by 9/8. But it's more because it's a separate, lower volume, market segment.

    Linus Torvalds On The Importance Of ECC RAM, Calls Out Intel's "Bad Policies" Over ECC

    ECC doesn't prevent rowhammer, but it does mitigate it. All single bitflips are reported, and if nothing else, the interrupts for reporting will slow down further attempts. All (most?) double bit flips are reported uncorrectable and are likely to halt the machine (depends on your os and the...

    Linus Torvalds On The Importance Of ECC RAM, Calls Out Intel's "Bad Policies" Over ECC

    The 'best' way to test ECC is to run with your ram at intentionally too tight of timings, or too low of voltage, so that it will have errors. And confirm that reporting is working. I saw in the mailing list thread there is a fault injection tool for AMD processors, that could work, too; if so...

    Win 10 download

    If it's an ISO, just dd it to your usb drive and it'll probably work.

    Is Noctua overkill if not overclocking 5900X?

    Noctua makes a bunch of coolers, which one did you have in mind? Regardless, none of them look that extreme, as long as it fits in your case, and doesn't bump into ram or whatever, it's not overkill. The low profile (NH-L9a-AM4) would be underkill unless that's all that'll fit. The cooler you...

    wont start with 4750g.. help

    I built two 4650g systems recently, and plopped existing Windows installs from Intel mini desktops; no obvious problems. I'm using a Gigabyte a520 board, but haven't tried its F11p bios yet (I've got an earlier F11 beta on one, but waiting for a final build, because I didn't see any significant...

    Blocking SYN-Flood Attacks on macOS?

    Data is big is why you only store headers, not the whole packet. Maybe you can store 5-15 minutes, and save the buffer the first time your script triggers in a day? Maybe even just 90 seconds. It'll be a lot to sift through in wireshark, but often there's a big change in packet rate, and there's...

    Blocking SYN-Flood Attacks on macOS?

    Intermittent issues are almost worse than hourly incidents. ugh. If you have the storage space, I'd really try to get some form of continuous tcpdump. If you have enough space to do something like tcpdump -s 40 -G 60 -w /tmp/tcpdump%H%M.pcap goes a long way to seeing what's going on. If you are...

    Feed 3080 with separate 8-pin inputs from PSU?

    Running two separate cables instead of using the daisy chain is probably a good idea. If the PSU side pins are the same type as the video card side pins, and the video card is pulling more current than the spec for a single connector, you're over the spec on the PSU side. Pulling more current...

    Intel Expands 10nm Manufacturing Capacity

    Process size numbers are more marketting than quantitative measurements. Intel's 10nm is pretty similar in actual feature size to TSMC's 7nm; Intel's 7 nm should be pretty similar to TSMC's 5 nm. More important is that Intel is having a very bad time getting yields/production volume out of 10...

    Ryzen 7 5800H

    4000 series desktop APUs are available, but limited. In some countries, shops can sell you a motherboard + apu combo; Lenovo has some desktop systems with them; otherwise you can import the chips grey market from china. Given that, and that AMD is pretty much fab limited for the foreseeable...

    AMD issues guidelines to retailers to prevent Radeon RX 6000 scalping

    That's alright, $MSRP + $1000 shipping. I'm not sure why people would pay much more than MSRP to get the latest systems now, when you could wait a few months and have more games to choose from, a better patched os, and maybe some production improvements.

    Intel's Manufacturing Outlook for the Future Doesn't Inspire Confidence in Successful Competition, According to Susquehanna Call

    Afaik, their 14nm is fine. Broadwell and Skylake were decent, but the problem is they just keep adding pluses and stupider code names, and maybe smashing in some more cores, but no real architecture improvements because the design teams are all working on 10nm designs that they can't ship...
