You might want to clarify "decent amount".

These guys make a range of oversize mugs.

That holds 52 fluid ounces (or ~1.5 liters). I use a smaller version.

If it's cooler outside than in, then in general opening the windows and having the AC on will cool things off faster than just one or the other.

Caveats might include the AC output being near a window and it being cooler inside near the window, or humidity. But absent that, sure, both will cool it down faster.

Once the inside temperature drops below outside, though, probably want to close the windows or turn off the AC.

I'd also add that if your AC has a ventilation-only mode that can pull outside air in

a window unit or ducted unit probably does, split mini won't, portable may not

that'll help cool the inside and be more energy-efficient than running the compressor, if you don't care about getting inside colder than ambient temperatures. Might also consider putting a box fan in a window or two, which could also drastically increase air turnover rate.

I live in a pretty comfortable climate and normally always have an open window and a small fan near the ceiling blowing air out the window, to have more airflow than would normally be the case with purely-passive ventilation.

If you're in an environment that doesn't get much humidity

the Southwest in the US is a good example

you might also consider an evaporative cooler, which won't give you the potential very cold temperatures of an air conditioner (given enough power), but will cool things below ambient temperatures without needing much power.

This appears to be from three months ago. It sounds like Imgur can ban IPs

I assume that this is a tempban.

The above study lists success rates for requesting images on various VPNs. NordVPN is at 98%, ExpressVPN 97%.

It also says that free VPNs have a far lower success rate, as their IPs tend to be blacklisted.

slow

rsync is pretty fast, frankly. Once it's run once, if you have -a or -t passed, it'll synchronize mtimes. If the modification time and filesize matches, by default, rsync won't look at a file further, so subsequent runs will be pretty fast. You can't really beat that for speed unless you have some sort of monitoring system in place (like, filesystem-level support for identifying modifications).

Most Unix commands will show a short list of the most-helpful flags if you use --help or -h.

I would generally argue that rsync is not a backup solution.

Yeah, if you want to use rsync specifically for backups, you're probably better-off using something like rdiff-backup, which makes use of rsync to generate backups and store them efficiently, and drive it from something like backupninja, which will run the task periodically and notify you if it fails.

rsync: one-way synchronization

unison: bidirectional synchronization

git: synchronization of text files with good interactive merging.

rdiff-backup: rsync-based backups. I used to use this and moved to restic, as the backupninja target for rdiff-backup has kind of fallen into disrepair.

That doesn't mean "don't use rsync". I mean, rsync's a fine tool. It's just...not really a backup program on its own.

Flash games tended to use vector art. This uses some flat color areas, but I'm pretty sure that that's hand-drawn raster.

That's going to probably either encourage a lot of people in the UK to get VPN service or leave a whole lot of users staring at broken image icons.

OOMs happen because your system is out of memory.

You asked how to know which process is responsible. There is no correct answer to which process is "wrong" in using more memory

all one can say is that processes are in aggregate asking for too much memory. The kernel tries to "blame" a process and will kill it, as you've seen, to let your system continue to function, but ultimately, you may know better than it which is acting in a way you don't want.

It should log something to the kernel log when it OOM kills something.

It may be that you simply don't have enough memory to do what you want to do. You could take a glance in top (sort by memory usage with shift-M). You might be able to get by by adding more paging (swap) space. You can do this with a paging file if it's problematic to create a paging partition.

EDIT: I don't know if there's a way to get a dump of processes that are using memory at exactly the instant of the OOM, but if you want to get an idea of what memory usage looks at at that time, you can certainly do something like leave a top -o %MEM -b >log.txt process running to get a snapshot every two seconds of process memory use. top will print a timestamp at the top of each entry, and between the timestamped OOM entry in the kernel log and the timestamped dump, you should be able to look at what's using memory.

There are also various other packages for logging resource usage that provide less information, but also don't use so much space, if you want to view historical resource usage. sysstat is what I usually use, with the sar command to view logged data, though that's very elderly. Things like that won't dump a list of all processes, but they will let you know if, over a given period of time, a server is running low on available memory.

I'm the other way. I'd rather have battery life on cell phones, and turn the refresh rate down.

On a desktop, where the power usage is basically irrelevant, then sure, I'll crank the refresh rate way up. One of the most-immediately-noticeable things is the mouse pointer, and that doesn't exist on touch interfaces.

Wikipedia: Ship's cat

The ship's cat has been a common feature on many trading, exploration, and naval ships dating to ancient times. Cats have been brought on ships for many reasons, most importantly to control rodents. Vermin aboard a ship can cause damage to ropes, woodwork, and more recently, electrical wiring. In addition, rodents threaten ships' stores, devour crews' foodstuff, and can cause economic damage to ships' cargo, such as grain. Vermin are also a source of disease, which is dangerous for ships that are at sea for long periods of time. Rat fleas are carriers of plague, and rats on ships were believed[a] to be a primary vector of the Black Death.[2]
