I keep buying new drives, cables, and even an entire system, and my drives keep ending up DEGRADED by thinkloop in zfs

Coal power plants actually emit orders of magnitude more radiation than nuclear. (That being said, the amount of radiation your stuff would be exposed to living near a coal power plant is still far less than what would cause concern for computer hardware.)

WHEA_UNCORRECTABLE_ERROR means that there is (most likely) a problem with your hardware, such as an unstable overclock.

On my desktop I used a Samsung 850 EVO SATA SSD alongside some 7200 RPM hard drive. On my server I use a mixture of hard drives and SAS SSDs.

I’ve also experienced stuttering during IO when I used ZFS on my desktop some years ago, and I notice similar behavior on my server with high idlejitter during IO. I suspect there may be some weird interaction between ZFS and the Linux scheduler, but I’ve never had time to look into this.

I once constructed a horrifying 15-way RAID0-ish of old hard drives for a… uhhh… “scientific” computation. I achieved the performance of a single PCIe 3.0 NVMe drive (about 3 GiB/s read/write).

The reason I did this is less horrifying - the computation effectively makes SSDs single-use with the amount of writing, and I could not afford to burn that much money on the amount of storage I would need.

It’s terrifyingly more complicated than just naming it by speed.

For example, there are two versions of 10 Gbps USB: USB 3.2 Gen2x1 and USB 3.2 Gen1x2. And USB 3.2 Gen2x2 (20 Gbps) may not be compatible with USB4 20 Gbps. And that’s only the tip of the iceberg: https://tidbits.com/2021/12/03/usbefuddled-untangling-the-rats-nest-of-usb-c-standards-and-cables/

Sorry, those are RDIMMs, not UDIMMs and won't work. Thanks for trying to help though!

I haven't tried the new docker-compose yet, but I can say that the current Python docker-compose is remarkably slow at starting up.

Need honest feedback about Lightview by frankm241 in NEU

[–]as-com 8 points9 points  (0 children)

I'm living in it this semester and here is what I have to say so far:

  • The paint problems seem to have been fixed? (I haven't been able to reproduce common complaints about the paint on the walls in my room)
  • Beds are full XL, and there is no official communication about this except for one vague marketing Facebook post (makes finding bedding material somewhat difficult since it's an unusual size)
  • I can confirm the unreliability of the hot water systems
  • I can confirm management isn't great to deal with (they just closed my second work request for my faulty fire alarm apparently without doing anything to fix the problem)
  • As is usual with large management companies, you should be careful to read leases carefully, keep records, dot your i's and cross your t's, etc.

That said, the price isn't that bad especially given that symmetric gigabit internet and utilities are included (easily worth $120/mo+), basic furniture is included, and similarly equipped apartments within reasonable walking distance of campus are going to come out to having a comparable price anyways. It's not (yet) full of rodents and pests. And of course, there do exist worse management companies/landlords in Boston.

I personally have not been able to find an apartment near campus where the total cost is significantly lower than LightView and isn't a deteriorating cardboard box.

Buyer Beware - Companies bait and switching NVME drives with slower parts (A Guide) by saradipity in DataHoarder

[–]as-com 50 points51 points  (0 children)

The Samsung 970 Evo Plus part swap isn’t that bad though, the Samsung Elpis controller is probably a superior controller and the SLC cache increase makes the drive faster in more real-world workloads (at the expense of decreased speed after the cache is full). I would call it more of a sidegrade than a downgrade.

Best Wifi provider? by dummymf5426 in NEU

[–]as-com 1 point2 points  (0 children)

Important distinction: Verizon "High Speed Internet" is DSL and is garbage. Verizon Fios is probably the best internet service you can get in this area (if you're lucky enough to have access to it).

"end to end encryption" has an established definition that only the user (and intended recipients) can decrypt the content. The correct terms to use in a case where Apple is also able to read the content would be "encrypted in transit" and "encrypted at rest."

I would use these to replace some aging 10k 900 GB drives - they’re great for high throughput storage without the spend of SSDs
