When a job listing says that the position requires "working knowledge" of a given product, what level of proficiency would you take that to mean?
"Working knowledge of SQL" in an app support position seems like it could mean any number of things. I've done some very light DBA tasks in the past and would be comfortable migrating or restoring instances or writing simple queries, but ughhhhh everything about hiring is terrible
For me, "working knowledge" equates to: Do you know what this is/what it does? Can you do some basic tasks and troubleshooting with it? Would you feel comfortable and able to expand your knowledge on this with experience and further training on it?

My general take on these has been: is it supported in your environment? Could you learn about it if need be? Apply and be up front about what you think you can do, let them decide. Generally a job posting is some garbage some HR person half filtered through the hiring manager and then copied from a competitor and tells you little.
Yeah, in app support context that reads as "I shouldn't have to explain how SQL works, so if you need to research something you can connect and query if given a data dictionary or similar."

Anyone know of any search alternatives when you have a massive number of files?
Client has over 4 million files in one of their network folders which is giving me a search index database 250GB in size. I personally use a freeware program called Everything and it works great as an admin, but for regular users I would rather give them something simple to use in place of the Explorer search window.
Because if you're going to attempt to squeeze that big black monster into your slot you will need to be able to take at least 12 inches or else you're going to have a bad time...
We have an FTPS server that we let some customers access if they need to send us files on an automated basis. I'm migrating it over to a new VM and I did a usage audit and found that some of the accounts for this server have never been used. Others haven't been used in over a year.
Naturally the account managers for those customer relationships are telling me that I need to migrate those customers over anyway (which includes reaching out to them and helping them log in to the new server)
How about

$1200 for one device? We aren't made of money, you know!
It was that somehow, from within the derelict-horror, they had learned a way to see inside an ugly, broken thing... And take away its pain.

We have a decrepit old environment monitoring system that is way out of support
It isn't our only line of defense. The facilities team has an HVAC vendor that monitors for temperature (not moisture though) so we aren't totally fucked if our ancient enviromonitor fails
But IT has no visibility into the HVAC so that's not ideal.
Something about using Pis and open source software for this appeals to me.

Wow. Coworker told me that a sysadmin he knows at some other company lost 600 hosts this weekend.
The datacenter was 90 degrees C and shit died. (that's 194 in Weirdo Fahrenheit Units)
how does that even happen
Man, a Watchdog device costs like $1200. How did they not know when it hit half that temperature??
They probably did, but that many servers we're probably talking a couple hundred thousand watts and that's going to warm up a sealed room real quick. If it was a sudden total ac failure, by the time a dangerous temperature spike was detected, individual systems may not necessarily still have enough time to automatically safely shut down servers completely before they cooked. And it's not like you can safely send people in there for manual intervention once it hit those kinds of temperatures.
Just remember that half the people you meet are below average intelligence.

Wemos D1 Mini plus an SHT30 shield for measuring temperature and humidity
10 bucks or something.
Power over micro USB, connect to wifi, write a quick hack that tracks temperature over MQTT, have a Raspberry or whatever with Node-RED and mosquitto that sends it on to the Grafana/Prometheus data-store of your choice, set up alerting.
I call this "nice weekend project".
Here's the Node-RED dashboard monitoring my living room. (Also get something better than the SHT30, it's absolutely not 25 degrees in here.)
For real though, stuff like temp monitoring is $$$$ and this is definitely in the realm of DIY for system admins.
We wanted a temperature probe for our fridge to make sure our meds didn't go outside of ranges and it was going to cost us something like $5000 for something that's just a meat thermometer and a gauge outside of the fridge that can send alerts to emails. If we wanted the cell phone card in case the power went out (likely if the fridge falls outside of a range) that added like another $3000 or something dumb.
not a doctor, not a lawyer, examples I use may not be fully researched so don't take out of context plz, don't @ me

Yeah, can confirm. Unfortunately there is a specific hardware vendor that some of our research partners require us to use that outputs the historical temp data in some truly awful format.
Yeah we use room alert here, but I'm super interested in what you come up with @Feral because I need to replace the one we have because it's super old, so old I can't even update it.
Also, in cases where server room AC has failed, our server room has climbed to 120 F pretty quickly, before I get the door open and start blowing cool air into it with warehouse fans (I can bring it down to 78 or so that way). I think the big thing is that there's nowhere for the hot air coming out of the servers to go, so they're just recycling and re-heating it.

I guess if I was in the situation where I could lose 600 hosts to near water-boiling temperatures, I would do my best to automate shutting them down at a certain temperature long before that. Seems like something that would be worth the time and/or money to invest in.

This is not a server room. This is putting your stuff in the broom closet and hoping for the best.

Oh I'll be the first to say we don't have a proper server room. There was talk of building a proper one years ago and then it fizzled into nothing due to cost.
First place I worked in, back in 2006 (fack I'm getting old), had their servers in a converted file room. there was a rack, and newer servers that were rack mounted were in there, but the older servers were all tower servers, and were all sitting on a bread rack. Literally, a bread rack.
About 8 months later we built a proper server room in the building.

I'm assuming, based on your original story, that the door doesn't have any sort of louvred vent for air exchanges? And I'm also assuming that's because "people complain about the fan noise".

As a counter example, our small on-site server room has no open venting as a requirement of the "electronics-safe" fire suppression system in it.
Years and years ago, I worked at a place that had their mainframes housed in a reinforced concrete bunker. The door was at least 2 feet thick and I recall it took the motors a good 30 seconds to open. Always reminded me of that giant Encom door from Tron. The first day they gave me a tour of the place and after being introduced to the techs that actually worked in that room all day, got the dire warning about how if you were ever in there when the Halon alarms went off, you'd have about 20 seconds to reach the oxygen masks before you passed out and died. Always been rather glad I've never had to work with Halon since.
Just remember that half the people you meet are below average intelligence.
Story from a couple of years ago. One of our customers had a large office near my hometown and a smaller office a bit further away. Usually I was at the main office, but occasionally I needed to go to the smaller office for a printer or something. Smaller office had like 20 people in it and a small server in a small locked supply room. This office was at the fifth floor in a larger building.
Arriving there in the afternoon, the receptionist greets me: "Good you are here, there is dust on the server. Can you check if it's still working?"
Sure, I'll go check. I open the door and everything is covered in white dust. The outside wall has four holes in it, each about 10-20 cm in diameter (again, this is on the fifth floor). Turns out the building next to it was being demolished and they accidentally hit our building. The server was still running (and luckily I had already moved all of its roles to VMs at our data-center as we upgraded the network line a couple of months earlier and a local server was no longer needed).

At my old job we lost a whole data center because the cooling system went down.
One of the many reasons it's an old job.

That shouldn't be possible even if the HVAC fails
Maybe just the CPU was running at 90C? That's certainly in the realm of possibility.
