Unless I'm misreading it which is possible it's awfully late, he said he processed 60,000 rows didn't find what he was looking for but his hard drive overheated on the full pass.

Discs don't overheat because there was load. Even if he f***** up and didn't index the data correctly (I assume it's a relational database since he's talking about rows) The disc isn't just going to overheat because the job is big. It's going to be lack of air flow or lack of heatsink.

I guarantee you he was running on an external NVMe, and one of those little shitty-ass Chinese enclosures. Or maybe one of those self immolating SanDisk enclosures. Hell, maybe he's on a desktop and he slept a raw NVMe on his motherboard without a heatsink

There are times when you want a brilliant college student on your team, But you need seasoned professionals to help them through the things they've never seen before and never done before.

Somehow I feel over clicking without understanding of the consequences sounds like something a techbro would do

Can't be a relational database, Musk said the government doesn't use SQL.

This cannot be real, wtf. This is cartoon levels of ineptitude.

Or sabotage by someone heading out? Please let this be resistance sabotage they haven’t noticed yet.

You guys arent running your software off raspberry pi's with sdcards from the gas station?

Look, all I’m saying is give Pis a chance.

You're not supposed to place your laptop directly in the lap of your fur suit. Always leave an air gap for ventilation, smh.

Either she knows something novel, where processing data using voice coils is somehow beneficial, or is someone who calls their computer a ‘hard drive’, which summarily negates any legitimacy of technical competence.

Or wrote the code using AI without checking what it exactly does.

[–] Threeme2189@sh.itjust.works 5 points 1 hour ago

The AI probably used bogosort or something equivalent

“I store my records on vinyl. You’ve probably never heard of them.”

[–] GreenKnight23@lemmy.world 38 points 7 hours ago (1 children)

I smell something, but it's not overheating electronics.

I've processed over 5 million records on a laptop that's almost 10 years old. it took two days to get my results.

there's no way 60,000 records overheated ANYTHING.

Doesn't actually say that 60k overheated his drive. He says that he ran a run on 60k, and that he couldn't do the whole database due to overheating. Two unrelated statements except that 60k is the lower bound for what he could process.

Doesn't mean he knows what he's doing though, as pretty huge datasets are processable on quite modest hardware if you do it right.

[–] GreenKnight23@lemmy.world 3 points 4 hours ago

that's somehow worse.

a "data analyst" couldn't cut up the work into a parallel processes and run them synchronously? what the actual fuck?

"sorry, I can only do 60k at a time."

just fucking split them up into 6 parallel batch processes running 10k at a time. it's fucking math, not rocket science. I'm not even an analyst and I could fucking do that much.

[–] jkercher@programming.dev 26 points 7 hours ago (1 children)

60k rows of anything will be pulled into the file cache and do very little work on the drive. Possibly none after the first read.

[–] Sprocketfree@sh.itjust.works 3 points 4 hours ago

Not if each row is pi!

I didn't know hard drive overheating was a thing. Should I be worried that my 5 year old hard drive is about to overheat. I mean is this actually a floppy disk or something?

[–] melpomenesclevage@lemmy.dbzer0.com 8 points 4 hours ago

it is a thing, but any competently designed computer should have things in place to prevent this.

unless you're an arrogant dipshit and disable all the hardware safeties on your computer to make it go faster and wear harder.

When an HDD works continuously it can heat up to above 60 °C if proper air circulation is not allowed, which can cause a very premature failure. In fact, it should be kept under 40 °C to achieve the intended lifespan. Unfortunately, PC cases are usually not great at removing heat from the HDD by default.

As for your drive, it most likely has a temperature sensor so it can be displayed by various utilities.

it is, in the select event that your platter bearing fails, in which case it would be very, very obvious.

I'm a data engineer that processes 2 billion row 3000 column datasets every day, and I open shit in Excel with more than 60k rows. What the hell is this chick talking about?

[–] zenpocalypse@lemm.ee 20 points 8 hours ago (1 children)

Seems like a good excuse to someone who doesn't know what they're doing and needs an excuse because why they haven't completed it yet?

The whole post is complete bs in multiple ways. So weird.

Some interesting facts about excel I learned the hard way.

It only supports about a million or so rows
It completely screws up numbers if the column is a number and the number is over 15 digits long.

Not really related to what you said, but I'm still sore about the bad data import that caused me days of work to clean up.

I work in insurance in Brazil, by standards of our regulatory body, claims numbers must be a string of 20 numbers (zfill(20) if needed). You can't imagine the amount of times excel had fucked me up rounding down the claim numbers, this is one of the first things I teach to my interns and juniors when they're working with the claims databases.

Are you telling me there’s a difference between an inner and a cross join?

Cross join is obviously faster, I don’t even have to write “on”

What in the fuck is this idiot doing? I've process datasets far larger than that and never once have I run into a hard drive "overheat". I mean what level of incompetence do you have to have to get a hard drive to overheat processing a measley 60K rows of data?
