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?

[–] KillingTimeItself@lemmy.dbzer0.com 10 points 10 hours ago (8 children)

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

When the only thing that is stopping kids from dismantling your government is an O(N^N) algorithm

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”

Hard drive was made by Tesla

[–] zalgotext@sh.itjust.works 101 points 16 hours ago (6 children)

my hard drive overheated

So, this means they either have a local copy on disk of whatever database they're querying, or they're dumping a remote db to disk at some point before/during/after their query, right?

Either way, I have just one question - why?

[–] Bosht@lemmy.world 44 points 14 hours ago (1 children)

I'd much sooner assume that they're just fucking stupid and talking out of their ass tbh.

[–] kautau@lemmy.world 17 points 12 hours ago* (last edited 9 hours ago)

Same as Elon when he confidently told off engineers during his takeover of Twitter or gestures broadly at the Mr. Dunning Kruger himself

Wonder if it’s an SQL DB

Elon probably hired confident right wingers whose parents bought and paid their way through prestigious schools. If he hired anyone truly skilled and knowledgeable, they’d call him out on his bullshit. So the people gutting government programs and passing around private data like candy are just confidently incorrect

Even if it was local, a raspberry pi can handle a query that size.

Edit - honestly, it reeks of a knowledge level that calls the entire PC a "hard drive".

Have you ever heard of case of overheating hard drives within the last decade?

[–] spooky2092@lemmy.blahaj.zone 55 points 15 hours ago (3 children)

Plus, 60k is nothing. One of our customers had a database that was over 3M records before it got some maintenance. No issue with overheating lol

[–] surph_ninja@lemmy.world 30 points 15 hours ago* (last edited 15 hours ago) (1 children)

I run queries throughout the day that can return 8 million+ rows easily. Granted, it takes few minutes to run, but it has never caused a single issue with overheating even on slim pc’s.

This makes no fucking sense. 60k rows would return in a flash even on shitty hardware. And if it taxes anything, it’s gonna be the ram or cpu- not the hard drive.

I literally work with ~750,000 line exports on the daily on my little Lenovo workbook. It gets a little cranky, especially if I have a few of those big ones open, but I have yet to witness my hard drive melting down over it. I'm not doing anything special, and I have the exact same business-economy tier setup 95% of our business uses. While I'm doing this, that little champion is also driving 4 large monitors because I'm actual scum like that. Still no hardware meltdowns after 3 years, but I'll admit the cat likes how warm it gets.

750k lines is just for the branch specific item preferences table for one of our smaller business streams, too - FORGET what our sales record tables would look like, let alone the whole database! And when we're talking about the entirety of the social security database, which should contain at least one line each in a table somewhere for most of the hundreds of millions of people currently living in the US, PLUS any historical records for dead people??

Your hard drive melting after 60k lines, plus the attitude that 60k lines is a lot for a major database, speaks to GLARING IT incompetence.

My one question would be "How?"

What the hell are you doing that your hard drives are overheating? How do you even know it's overheating as I'm like 90% certain hard drives (except NVMe if we're being liberal with the meaning of hard drive) don't even have temperature sensors?

The only conclusion I can come to is that everything he's saying is just bullshit.

[–] Auli@lemmy.ca 19 points 13 hours ago

They have temp sensors. But have never heard of a overheating drive.

From the same group that doesn't understand joins and thinks nobody uses SQL this is hardly surprising .

Probably got an LLM running locally and asking it to get data which is then running 10 level deep sub queries to achieve what 2 inner joins would in a fraction of the time.

[–] _stranger_@lemmy.world 69 points 16 hours ago* (last edited 16 hours ago) (3 children)

You're giving this person a lot of credit. It's probably all in the same table and this idiot is probably doing something like a for-loop over an integer range (the length of the table) where it pulls the entire table down every iteration of the loop, dumps it to a local file, and then uses plain text search or some really bad regex's to find the data they're looking for.

[–] morbidcactus@lemmy.ca 31 points 15 hours ago

Considering that is nearly exactly some of the answers I've received during the technical part of interviews for jr data eng, you're probably not far off.

Shit I've seen solutions done up that look like that, fighting the optimiser every step (amongst other things)

As a reasonably experienced "data guy," this seems obviously laughable, but the discussion on X is scary. This guy is a savior in the MAGA world.

We can criticize and poke fun all day, but it doesn't matter much if our message isn't challenging the mindset of those with other opinions.

How do we make better use of our time to impact outside opinion?

[–] masta_chief@sh.itjust.works 8 points 12 hours ago (3 children)

We must make better memes

I'm not even joking, the world runs on memes now. It's fucking stupid, but we must shitpost to save ourselves

I've been told violence isn't the answer and we shouldn't just shoot nazis and nazi enablers dead.

The way most people change their mind isn't based on facts or figures, but emotions. Specifically, in-group belonging. For most people, and this certainly includes me and you some of the time, what our in-group believes is more compelling than an out-groups supposed facts.

They see that guy as someone in their group so they believe him. They see you as a bad outside bad bad bad liar, so nothing you say is likely to get through. (This comic is worth reading on this topic: https://theoatmeal.com/comics/believe )

If you want to change someone's mind, they have to see you as in-group. Not necessarily the same group as what you're arguing with. We all belong to many groups. American, new yorker, white guy, middle aged, yankees fan, etc etc there are many such slices. Like how you can't get a republican to recycle by appealing to environmental concerns (because environmentalists are out-group, so fuck them), but you might be able to get them to recycle via something like "only american ingenuity can turn trash into bridges and tanks!"

This takes a lot of time and effort, and if you don't get them to stop hanging out with the other group, you won't make any lasting changes.

So I think you'd need a multi prong approach:

  • Get them off bad media. Facebook, fox news, etc. This is reinforcing their bad beliefs. Because they see this stuff as trustworthy in-group, it goes right into the worldview.
  • Get them to stop hanging out with their shitty maga-hat friends. This is the social in-group that's reinforcing bad beliefs.
  • Get them to trust you.
  • Gently introduce the idea that maybe the extreme right doesn't have their interests at heart, etc

All of which takes a lot of time and effort, and your opposite number is basically trying to do the same thing. Except they have fox news, trump, and such in their corner.

And, again, I'm told we definitely shouldn't just shoot extreme right wingers and other nazi sympathizers dead. Nor should we burn their houses down. If we're an emergency responder, we definitely shouldn't let them die while thinking to ourselves "they would let so many die. without a thought, their passing deserves no mourning" or similar.

You should definitely nullify if you're on a jury and someone allegedly did violence to a shitty ceo or red-hat, though, bu that's getting off topic.

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?

I cannot believe these people make more than me lol.

[–] _stranger_@lemmy.world 29 points 16 hours ago* (last edited 16 hours ago) (6 children)

They make nothing. They're compensated for destroying things, and considering it's musk, they're likely given relatively little money in return for their time.

Even if the only thing you do all day is sit on the toilet and yell at the Internet, you're already a bigger net positive on society.

60k isn't that much, I frequently run scripts against multiple hundreds of thousands at work. Wtf is he doing? Did he duplicate the government database onto his 2015 MacBook Air?

[–] easily3667@lemmus.org 128 points 18 hours ago (3 children)

60k is laughably, embarrassingly small. It's still sqlite-sized.

[–] morrowind@lemmy.ml 46 points 16 hours ago (4 children)

Sqlite can easily handle millions of rows. Don't sell it short

A TI-86 can query 60k rows without breaking a sweat.

If his hard drive overheated from that, he is doing something very wrong, very unhygienic, or both.

Wow.

I've been processing a couple of billion rows of data on my machine, the fans didn't even come on. WTF are they teaching "experts" these days, or has Elmo only hired people who claim that they can "wrangle data" and say "yes" ?

[–] wise_pancake@lemmy.ca 4 points 9 hours ago (1 children)

60k rows is generally very usable with even wide tables in row formats.

I’ve had pandas work with 1M plus rows with 100 columns in memory just fine.

After 1M rows move on to something better like Dask, polars, spark, or literally any DB.

The first thing I’d do with whatever data they’re running into issues with is rewrite it as partitioned and sorted parquet.

No he also hire people who created a script to make fake ballots with a bias.

This shit sounds like when you're mom tells you that the Facebook printed out her bank statement on the tax machine. I'm not smart enough to even guess how you did something dumb enough to make that happen.

How bad are you at writing queries? How does your hard drive overheat even under 100% load? Do you have it smothered under a blanket? Did you crack it up and expose it to cheeto dust? What does running a query on your, presumably, remote database even have to do with your harddrive in the first place? Are you trying to copy the entire database locally to a laptop? Do you know how to tie your shoes yet, or are you still on the velcro?

This shit sounds like when you’re mom tells you that the Facebook printed out her bank statement on the tax machine.

My dear sweet mother asked me somewhere around 2005-06 "If we can fax paper, why not groceries, or pizza delivery?"

Apparently she had believed, for decades, that fax machines literally transported physical paper over phone lines. She has a college degree, and my family is wealthy.

Do not underestimate the mind boggling technical and scientific ignorance of old people who should know better.
