Yeah just buy $200+ screens instead of $5 Monoprice adapters. 75% of the people here are still on VGA.

I'd go with cables over the adapters. We've had a couple of the Monoprice adapters break. The cables have been holding up fine so far.

Also a cable is one less join and I'm a bit of a sperg about stuff like that for no real reason. I don't like seeing adapters hanging off the ends of things because far too often people assume that it's there for them to steal.

This is like the people who complain that their browser is slow and takes a lot of memory and you see that they have a hundred tabs open. Just close tabs when you're done with them. "But I might need it later." So bookmark it, that's what bookmarks are there for. :argh:

I had to transfer two dozen open tabs and the browser history between a pair of laptops the other day. Thankfully they used Chrome, so the tabs were actually remarkably simple thanks to an extension, but seriously.

An email came in...

quote:

On Thursday, an application resource elevated himself to root privileges on --------, and then promptly executed an rm –fr /* on this development host.

His intentions were to clean up a file system, unfortunately, the /* means root drive + wildcard and he added the –fr options (force and recursive)

The host is unbootable except for failsafe which is a non-usable state. We have recorded all the pertinent network and config info that hasn’t been removed / damaged in anticipation the host will need to be rebuilt.

Current status:
- A new OS was laid down and patched on Monday/Tuesday

Not remotely, although it's generally executed by sysadmins who realize that their "rm -rf ./*" is taking a little long, see the space between the period and slash, and frantically pound Control-C in the hopes that /bin still exists.

e: it's also worth noting that these tend to spawn the most interesting hack stories too, as you try to figure out how to bring your system back into a working state when you're in a running shell but missing cat, ls, bash, rm, and basically everything but netcat.

It happens sometimes. Especially when

quote:

an application resource elevated himself to root privileges

Giving people who have no business being on a server root access will usually bite you in the rear end eventually. We have a few servers at my place where the devs have somehow wrangled root sudo access for themselves, and it's terrifying. It's also annoying because they do poo poo like reboot their production servers in the middle of the day with no notice and make our monitors freak out, but then I also get weekend calls from them wanting me to create a bunch of directories and change permissions or something else that they could easily do with their sudo access (or even sometimes without it), which I can't ignore or refuse because their project is super-critical.

Back when I was a tier I tech support rep at a web hosting company, one of my fellow reps was trying to remove a customer's directory named "etc" and ran "rm -rf /etc" instead. On a BSDi system, so /etc was where everything that made the system actually function lived. :cripes: Our Unix sysadmin and I ended up staying six hours late trying to fix it, since the server was in California and no one there had or knew how to make a rescue disk. I ended up having to compile sash on another of our BSDi systems (which was a bitch in and of itself), and we had to upload it to the broken server via FTP (one of the few things that still functioned) and overwrite some other executable binary file with it because we couldn't chmod anything. But we finally did get the thing working again eventually.

The rep who broke it learned her lesson and never did anything like that again, but we had another rep there who removed stuff by accident all the time and finally got all the tier I techs except me banned from accessing some of our platforms because he kept breaking 'em. They wouldn't fire him because he was engaged to the owner's friend's niece.

Mustache Ride posted:

This. rm -rf with wildcards is always, always, always a bad idea. Or really any recursive command with wildcards. If you simply can't avoid it for some reason (and there really is never a reason), at the very least you should take the time to check with an ls using the same pattern to make certain you're only going to touch what you expect to touch.

(Protip: did you know that ".*" will match ".." and run your recursive command on the parent directory of your target and everything underneath it? Learned that one the hard way when I was a terrible newbie; luckily it was only a chown -R and just took an hour or so to clean up... :v: )

ID10T traps like that are cool, but relying on any Unix tool to protect you from doing stupid poo poo is about the worst habit you can develop, because most of the time they won't. You should always assume that whatever command you've typed is exactly what's going to happen and double-check everything before you hit enter.

In practice, this is like "you should always run SELECT ..." and change it to destructive commands when you get the result set you want. It's nice in theory, but it's extremely easy to make a typo and miss it because you spend your whole day typing in a terminal, which is why many utilities (most of coreutils, yum, etc) prevent you from yourself a bit.

I'm not a fan of DP either, but since it's easy to get adapters for it I don't mind it, and it still supports way higher resolutions.
Also, DVI connectors seem to be better quality than VGA, at least they get stuck far less, and the screws seem to break/deform far less.

That's more a problem with Windows than DP though.

I've never had an issue with DP apart from finding out the DP cable I bought wasn't actually DP certified and would prevent my computer from booting. Pin 20 in the DP connector provides utility 3.3v and should not be connected in a regular male-to-male cable, but some cheap crappy cables have all pins connected which in my case made the graphics card throw a hissy fit.

Apart from using a lovely d-sub connector (with all the bullshit that guppy mentioned above), DVI is also limited to 2560x1600@60hz due to bandwidth limitations so it's close to becoming obsolete anyway.

And adding DP and mini DP to the mix really helps.

I mean there's what? 2 different types of DVI (nobody actually uses DVI-A) and 3 types of HDMI. Clearly the solution to this is to add two more plug types, and ones that are not electrically compatible too!

Though I agree with gently caress people who put DVI-D ports on things. At least just put a DVI-I socket and leave the analogue pins disconnected.
