comment Does zswap compress pages, that written to swap device?
From this LWN article it looks like pages are decompressed during resumed writeback. I don't know why this is, if this is a limitation of the Frontswap API or if the allocation of pages on the backing store is handled outside of zswap (or something completely different - I don't know much about memory allocation on modern systems...)

comment How to start a service automatically when Arch Linux boots?
If you don't need it until the desktop environment starts, there are various DE-specific ways to do it which are independent of Arch. For example, on Xfce.

comment Cloning a 512 sector size to Advanced Format WD Black drive
My guess (without doing any research) is that the new drive is using a larger sector size (that's what "Advanced Format" is) and this is confusing CloneZilla. Is it possible to reformat the new drive using 512-byte sectors? That might fix the issue. (If you have a 3TB+ drive, this won't work, but I imagine it would be fine for 1TB.)

comment Can the linux kernel enumerate pcie devices beyond what the bios can?
Maybe, I'm not sure (well, I don't think it's directly a BIOS limitation, as to my knowledge Linux (as with most modern OSes) doesn't directly call into the BIOS anymore). But are you sure the limitation is not with the hardware? You can't have more devices than the controller has available lanes, unless you have additional switching hardware.

comment Does “Offline” in Disk Management actually turn off (spin down) the disk?
From what I've heard, you can accomplish this by setting the delay appropriately in Power Management settings and then disabling indexing on the drive (and not doing anything that might access data there). (Also, if you're worried about data protection, the only real solution is to encrypt the drive.)

comment HDD recovery — linux does not see drive (fdsik -l)
The first thing is probably to check dmesg just to see if anything shows up. I would be surprised if the BIOS recognized the drive but the Linux kernel ignored it completely. This might give you some clue, at least.

comment HDD recovery — linux does not see drive (fdsik -l)
Well, if it doesn't show up in the BIOS at all, then that is a problem - there's no way to recover any data at all using software if it's completely non-working (unless you want to try swapping boards, which is not all that likely to work even on a desktop drive where it's physically relatively easy to do). If it does show up in the BIOS, there's at least a chance that you can recover something.

Can you see it in the BIOS?

comment What is the difference between 'physical' and 'logical' size?
Yes. Although next-generation filesystems like btrfs (maybe ext4 too, I don't know if it's in the kernel yet) support inlining small files along with the file metadata, so if it's below a certain size it won't take up an extra cluster. This means improved access time as well as potentially reduced space.

comment What happens if I use RAM of a faster speed than the CPU supports?
Certainly, but the information might be helpful to anyone else who finds the question.

comment What happens if I use RAM of a faster speed than the CPU supports?
It's not always a waste of money. For example, memory rated for 2133 MHz at 1.65V would likely be able to run at 1600 MHz at a lower voltage, decreasing power usage and heat generated, and potentially increasing system stability. If this matters to you, or if the price difference is small, it could be worth getting the faster memory. But for most users this will not be significant.

comment How to backup a bulletin board hosted by a 3rd party?
It's not as good as a database backup, but you might be able to get the content with a program like HTtrack.
