Depends on if you're a tits or an ass guy, I guess?

It depends. I've done it a few different ways:

• YOLO: especially with thugs like PHP you only affect one page at a time and with low traffic the odds of a problem is small
• Maintenance page: temporarily show a page. Some servers like IIS have this built in. Otherwise it's a simple update to httpd conf
• In a cluster environment, just take the node you're updating out of rotation, and only update one node at a time.
• Copy and switch like you suggested. Can be combined with any of the above and is a smart move if upload is slow or can be interrupted, or it's cumbersome to restore the old files

Edit: spelling

Yes, unless it is encrypted, in which case you need a way to decode that. You can even boot an OS from a USB thumb drive to recover files from a hard drive.

Is moving the drive to another computer as a secondary drive an option? Or put it in a separate USB enclosure? That way you don't need to boot it at all, unless it's encrypted or something.

Roughly in order of appearance. Personal devices only. I used many more for work.

To manage packages on the terminal, I personally like to use aptitude which has a nice visual interface to find, install, and remove packages. It also lets you resolve conflicts interactively. If you do not want a separate tool, you can use apt-cache search to search for new packages.

As is typical with Linux, there are multiple ways to do it. I found an article that outlines a few alternatives.

I switched to self hosted Piwigo after Flickr started threatening to delete my photos a while back.

It had an extension that let me import all my photos from Flickr. Not sure if that still works after they changed hands.

It's very easy to maintain; just click the update button in the Web UI. And it comes with a bunch of extensions.

This is the answer. Here in this US checks are still widely used, and sometimes, thanks to processing fees, the only payment except cash someone will accept. Mobile payments, though available, haven't really taken off here like in Europe.

You haven't lived until you've installed Slackware from floppy disks and compiled the necessary network drivers into the kernel by hand. Good times, but never again.

I grew up in Norway, but haven't lived there for some time. When I first read this I was like "bullshit. you can drink anywhere". But, I looked it up and you are correct. However, it is not very often enforced unless you're being a nuisance. Drinking and driving on the other hand is taken very seriously. Don't even gamble with that a little bit in Norway.
