In my system, the raid arrays seem to do periodic data scrubbing automatically. Maybe it’s something that’s part of Debian, or maybe it’s just a default kernel setting. I don’t think it helps much with data integrity – I think it helps more just by ensuring the continued functionality of the drives.
When it’s running, you can type cat /proc/mdstat to see the progress.
That command will also show you if there is a failing drive, so that you can replace it.
Just about anything. IRC, XMPP, Discord, whatever you call the chat built into Steam. AIM is discontinued now, but it used to be better than Teams is today.
Sure. First you set up a RAID5/6 array in mdadm. This is a purely software thing, which is built into the Linux kernel. It doesn’t require any hardware RAID system. If you have 3-4 drives, RAID5 is probably best, and if you have 5+ drives RAID6 is probably best.
If your 3 blank drives are sdb1, sdc1, and sdd1, run this:
mdadm --create --verbose /dev/md0 --level=5 -n 3 /dev/sdb1 /dev/sdc1 /dev/sdd1
This will create a block device called /dev/md0 that you can use as if it were a single large hard drive.
mkfs.btrfs /dev/md0
That will make the filesystem on the block device.
mkdir /mnt/bigraid
mount /dev/md0 /mnt/bigraid
This creates a mount point and mounts the filesystem.
To get it to mount every time you boot, add an entry for this filesystem in /etc/fstab
The man page at https://btrfs.readthedocs.io/en/latest/mkfs.btrfs.html says:
RAID5/6 has known problems and should not be used in production.
So those profiles have unknown, unspecified problems.
But btrfs is safe on top of md-based raid1/5/6. It also has the advantage that you only need to encrypt one volume.
While this may look like a good reason not to use the service, I learned of an even better reason just now from this article:
At the start of next year, GeForce Now will roll out a 100-hour monthly playtime allowance to continue providing exceptional quality and speed – as well as shorter queue times – for Performance and Ultimate members
Apparently you have to wait in line?!
Any regular hex nut works just fine as a jam nut. Basically, a jam nut is when you jam two nuts together. (It is gay, because the nuts do touch.)
And note that those nylon inserts kinda only work once. The bolt carves a thread into the insert when you insert it, so it will be weaker the second time you insert it.
Honorable mention: cage nuts. A square nut, permanently attached to a fastener that can snap into a special square hole in a 19 inch server rack. When you tighten the bolt against the nut, it tightens against the fastener, so that the nut, bolt, and fastener are secure against the square hole.
English has its flaws, but I don’t agree that that is one of them.
If anyone was hoping for women priests, give up on that. The Roman Catholic church would first have to retract both papal infallibility and ecumenical infallibility.
They have made too many definitive statements that women can’t be priests, and they have made definitive statements that their definitive statements are infallible, and must be agreed to by anyone who calls themself Catholic. It’s not even up for debate (unless all of the infallibility stuff is also up for debate).
For example:
I declare that the Church has no authority whatsoever to confer priestly ordination on women and that this judgment is to be definitively held by all the Church’s faithful.
They really painted themselves into a corner. While the rest of society moves forward with equal rights for historically marginalized groups, the Catholic church will be stuck with the effects of their early bad decisions (and some recent bad decisions) because they banned themselves from admitting when they are wrong.
It’s not really an order. Think of it as more like a threat.
I eagerly await your writeup on whichever calendar you think I need to know more about.
Unfortunately this won’t happen until October 31st 2600. Starting on March 1st in the year 2600, the Julian calendar (popular in centuries past, and still used in a few places) will differ by 18 days from the Gregorian calendar (the current worldwide standard calendar).
It happens that October 31st in the year 2600 lands on a Friday, and so the Julian October 13th, which lands on that same day, is also a Friday.
There may be a sooner Friday the 13th that lands on Halloween, if you know of other obscure calendars like the Hebrew, Islamic, or Chinese calendars. I don’t know enough about those to check.
The easiest way to disable unnecessary services is to uninstall them with aptitude, or whichever package manager you like. Try terminating services one by one, and see if anything bad happens. If nothing bad happens, you can probably uninstall it. On the other hand, if the system does get wonky a reboot should fix it. Or, you can research the services by name and decide whether to uninstall them. (avahi-daemon for example is a good idea to uninstall.)
To make the GUI not run, uninstall your display manager (gdm, xdm, nodm, or whatever) and uninstall your xorg server or wayland server. There may be GUI programs remaining after that, but they will only be consuming disk space, not RAM or CPU.
If the battery is old and holds little charge, you may save a few watts by removing it and throwing it away, instead of letting the system keep it topped off.
Get a power meter, such as a Kill-a-watt device. Then, experiment with different settings. If it’s consuming less than 30 watts, you’re probably fine. If you live in the US, one watt-year is about one US dollar (or a little more), so for every watt it consumes, that’s about how much you will pay per year for its electricity.

Beta testers should get a discount, or even get paid, in exchange for writing good bug reports. These people are fools for paying extra for earlier access to a bug fest.
I would never pre-order a game. That just makes it harder to refund it if it sucks.

Sounds like what you’re looking for is an ATX12V plug. It’s a 2x2 connector that normally has two yellow and two black wires. It normally goes into the 2x2 receptacle on the motherboard to power the processor. In this case, the eGPU enclosure needs it for some reason, maybe for more power.
The good news is that the 2x4 breakaway connector (called EPS12V I believe) that splits into two 2x2 connectors is probably compatible with this receptacle. One of the two 2x2 pieces of the connector should fit into the eGPU’s power receptacle, and the other won’t. If it fits, it is probably the right connector. If two of the wires going to that connector are yellow, and two are black, then it’s almost certainly the right connector.
You may have multiple of these 2x4 breakaway connectors. If so, they should behave identically, and you can break up any of them and try to fit the pieces into the ATX12V receptacle.
List of ATX power supply connectors: https://en.wikipedia.org/wiki/Power_supply_unit_(computer)#Connectors (without images, unfortunately.)
Don’t forget about the big 20-pin or 24-pin main ATX motherboard power connector. Your second power supply, since it is non-modular, will need something to simulate the motherboard’s power button. That’s can be as simple as a switch between the PS-ON wire (green) and any ground wire (black). But hopefully your eGPU has a place to plug in the ATX motherboard power connector, and handles that on-off switching for you.
I’ve seen “Domain Controller” and “Subscriber” for the sake of plausible deniability.
In the case of SPI, they want to keep intact the names MISO (master in, slave out) and MOSI. So they use things like “Main” and “Sub”.
I just hope federal services (like applying for a passport) don’t become Twitter-only after Trump appoints Elon as Secretary of Enshittification.
