Not only that, depending on where this vending machine is, it could be nothing more than a leased spot with the actual machine, inventory, and access keys owned by an off site company.

While the sign could be the best that employees of whatever store could do

I don't know why everyone is all shocked all of a sudden, there have been various scraper bots collecting text info for...many years now, LONG before LLMs came onto the scene.

That's chocolate milk which is amazing at any time, the post implies plain white milk

What's wrong with water? I usually just get water and ask for lemon slices to squeeze into it. Which is a game changer and they always have on hand because of the alcoholic drinks lmao

Sugar is sugar, HFCS found in sodas and juice with added sugars is more concentrated, but your body still sees it and treats it as sugar.

Which it also just happens to see as something to hoard because for our entire evolutionary timeline sugar was a rare resource to be had. It wasn't until the industrial revolution that we began being able to have sugar whenever and however we wanted. Which on the timeline of evolution is nothing but a blimp, a speck of sand.

Windows used to actually have cool theming capabilities in Windows 98 (And I think ME/2000) what the hell happened to that LMAO

cm0002 ,

It did more than "a few colors", compared to today's fancy modern theming systems it was def rudimentary, but with a single click Win 98 would change colors, the cursor, the entire sound pallette and even button images iirc. I was particularly fond of the Computer theme and the Space theme lol

cm0002 ,

Well shit, and it even has a pre built magisk module

Aaaand installed lmao

Only necessary on the ol spinning rust, with SSDs not only is it completely unnecessary, but it also burns extra writes.

Spinny's store data magnetically on the platter with 1s and 0s, SSDs store data on the NAND as a held charge. If there's a charge in the block it's a 1 if there's no charge it's a 0.

With spinny's, a file gets marked as "deleted" but the residual magnetic 1s and 0s will remain on the platter until eventually overwritten

With SSDs a file gets marked "deleted" and within no more than a few minutes TRIM comes along and ensures the charge on the NAND is released for that data, there's no residuals to worry about like with spinny's and is in fact necessary to ensure decent lifespans.

Computer data is never actually “deleted” until it’s overwritten with new 1s and 0s — operating systems simply cut off references to it.

That's not entirely correct, and I would expect a tech news site to know but ig not.

It's true with spinny's since they store data magnetically on the platter with 1s and 0s, but SSDs store data on the NAND as a held charge. If there's a charge in the block it's a 1 if there's no charge it's a 0.

With spinny's, when a file gets marked as "deleted" the residual magnetic 1s and 0s will remain on the platter until eventually overwritten like they say

But with SSDs, when a file gets marked "deleted" then within no more than a few minutes TRIM comes along and ensures the charge on the NAND is released (Which means that data is gone, permanently) for that data, there's no residuals to worry about like with spinny's and is in fact necessary to ensure decent lifespans.

ETA: Link to a study from last year on this

It could be or maybe the SSD has its own on-firmware TRIM schedule, but all major OS's execute a TRIM on a time based schedule no longer than every 10-15 minutes.

cm0002 ,

TRIM works outside the filesystem, it does not care about 99.9% of it, the only part it cares about is if there is a reference in filesystem to the block charges. No reference == data to be released

cm0002 , (edited )

This can happen when TRIM is disabled

Here's a study published last year I read that goes through this exact thing

In consideration of results obtained from the experiments, it concluded that the behavior of
Wear Leveling in different SSD manufacturers having the same storage capacities does not match.
It varies based on the number of files, types of files, and sizes. The recovery of files from different
SSD manufacturers showed different results. In all SSDs, not a single trace of any file found in
disk format scenario(s). Whereas, some of the data recovered in the delete case and from only one
drive. It clearly showed different behavior of data recoveries in format and delete cases.
The obvious finding from this study is that the time interval of image acquisitions played a
significant role, and the longer time interval supports few chances of data recovery because the
TRIM and Garbage Collection process effects clearing residual data from the drives

I doubt that the firmware is doing an overwrite of TRIMmed data. Rather, I expect it's marking it as having been TRIMmed, and so can report that it's zeroed to higher layers. If a higher layer queries the firmware for its content, sure, they might get zeroes returned. But if you can modify the firmware or otherwise bypass it, you may be able to get at the underlying media.

TRIM is garbage collection and is a part of the wear leveling system. The whole point of TRIM is to have the SSD only hold the charge it needs too for still in use (i.e. not deleted) data. It's the charge that damages blocks over time, so to extend lifespans it clears everything not needed. It's not overwriting data for security or anything per se, but rather just a result of its longevity processes

Now, I'm sure there are cheap no name SSD controllers out there with ineffective TRIM operations that just lie about the operation, but any controller worth its salt is gonna have proper TRIM.

There is also the "bad block" issue, where storage media can take blocks -- which may contain readable data -- out of use, so that higher layers cannot access them. That applies to rotational drives and it looks like SSDs do the same thing. Again, might require bypassing or modifying the firmware to get direct access. But there can be data leaked there.

Part of that process is to move the data to another block and release the charge to prevent further damage, it's possible the block is damaged in such a way that it won't even release the charge, but if that's the case it's incredibly unlikely to be readable.

I also wouldn't be terribly surprised if there is lingering information even after zeros are written to an SSD that might be recoverable if you could directly access the media, though I'm not familiar with the situation there. That is the case for rotational drives -- the drive platter itself is "analog", doesn't just store a discrete string of ones and zeroes at the physical level. I once knew a cryptographer who was working on quantifying that leakage for rotational drives.

Yea it's possible, but now you're in the needing x-ray machines, powerful microscopes, full clean room labs and people with extensive, specific skill sets which means $$$$$$$$$$$$$$$$$$$$ or in other words, state level budgets range. 99.99999% of people will be fine

cm0002 ,

The reason that TRIM enhances life by facilitating wear leveling is that it lets the firmware know that the block no longer has useful data

Ah I see the disconnect, TRIM doesn't live in the OS outside of the firmware, TRIM is part of the controller firmware and is exposed as an ATA command for the OS to utilize

The study I have linked in my original comment goes more in-depth

You're liable for your car no matter what

Nope, it should be law that if an auto manufacturer sells an autonomous driving system that they advertise being able to use while driving distracted then they are liable if someone uses it as advertised and per instructions.

What you wrote is probably an auto manufacturer executive's wet dream.

"You used our autonomous system to drive you home after drinking completely within advertised use and per manufacturer instructions and still got in an accident? Oh well tough shit the driver is liable for everything no matter what™️"

cm0002 ,

but right now they're not and drivers should be fully alert as if they are driving a regular vehicle.

Which is what would be per manufacturer instructions, which still falls under my definition

cm0002 ,

Ah I see, it didn't come across like it at first

cm0002 ,

except then I remember that some of my coworkers actually are stupid, so it's probably aimed at them.

I work in IT and have done these campaigns, if you're on Lemmy, you're probably not the target audience lmao

cm0002 OP ,

I don't mind having the choice at least, years ago Amazon did this with their Kindles (or maybe they still do, dunno). You were given a choice on their Kindle order page, save 40$ on an ad supported version or full price and ad-free. It even stacked (At least once anyways) with other sales they might have been running.

I chose the ad supported model... and then proceeded to root it and remove the ads LMAO

747.41kW, or around six and a quarter NVIDIA GB200 NVL72 racks. Max power consumption was rated for around 1.75MW.

I think my electric company would pay me a visit if I fired that bad boy up in my house lmao, to bad the auction closed already. Oh and it closed at 480k lmfaooo

It still takes two people to carry those huge thin TVs

Idk about that, I can reasonably carry up to a 65 inch by myself and I'm not particularly tall (not even 6 ft) so someone taller than me probably could conceivably carry a 75+ tv

cm0002 ,

I have, that's how I know lmao, no screen crack btw lol

cm0002 ,

Sooo, is there like a certain knuckle-cracking sequence to turn it off and on again or what? Lol

cm0002 ,

No one is being turned into a borg drone.

Damn. I finally thought this would be the year :(

This, everyone should go lookup those fire department videos where they demonstrate furniture catching fire with and without flame retardant. The ones without are scary AF

offered a $10 million reward to anyone who could reveal his identity

I wonder if he's going to send that to the DoJ now lmao

cm0002 ,

SSDs were properly destroyed

I hate when companies do this, SSDs do not need to be shredded, there's no security benefit whatsoever. You don't even need to do the whole "write 0s/random data X times" like with HDDs. So damn wasteful ugh.

cm0002 ,

Especially modern macOS, macOS has become...too distrustful of the user IMO. Maybe even as a pathway to getting their user base used to a locked down OS on a Desktop/Laptop for future expansion of that walled garden.

Sure, windows has system accounts with permissions levels above admin, like SYSTEM or TrustedInstaller, like macOS. But the difference is you can take control of one of these "Uber Admin Accounts", macOS does not.

Well I was, but then little Timmy called and he said I can just send it through the computor, so I scanned it but now I'm not sure what to do now, please help

Not having to maintain a bunch of shitty two stroke engines is phenomenal.

Kinda off topic, but this reminded me of the lawn mower I bought a few summers ago. It was on sale for like 200, it was an electric Li-Ion battery though.

It was my first Li-Ion mower, but not the first electric and the first electric was just...shitty...pros definitely did not put weigh the cons so I was hesitant, but bit the bullet anyways because that first electric had to have been like 15+ years ago so things must have improved

So glad I did, this MF is so damn quiet, I don't even need hearing protection AND I can mow at like 9PM because it's so quiet that the barking neighbor dogs are louder AND I don't have to fuck with gas and oil. I even picked up the same thing but the trimmer and weed whacker version at a thrift store. So now I don't have to fuck with has and oil and MIXING them just right for 2 strokes.

Even with the big battery they're still lighter than the equivalent 2 stroke.

Tl;Dr FUCK 2/4 stroke engine equipment, I'm never going back lmao

cm0002 ,

Many years ago, back when Marriot locked their non-shit WiFi behind a paywall I was able to get around it by changing some values (Iirc, I literally changed the price that was sent to the server to 0.00) with TamperMonkey lol no server side validation, no lookups, no checksums no verification of any kind lmao

So this doesn't surprise me in the least

cm0002 ,

not even turned off because many phones emit Bluetooth beacons and other data that can be recorded and traced

That's a bunch of bull, off is still off unless you have a reputable link/source that says otherwise.

No need to spread misinformation or conspiracy theories.

cm0002 ,

Ok I stand partially corrected, it's something that's coming but is not rolled out yet and looks like it'll need the latest phones so everything slightly older is still fine

cm0002 ,

Everyone: "Construction and Creative jobs will probably be the last to be automated!"

Computer Scientists: And I took that personally

Oh neat, finally a non-explody and/or unstable battery lmao

Pfft as if, P&F would write Linux entirely from scratch for "reasons" making it the best version of Linux ever seen and the proceed to take over the entire OS landscape in a matter of hours
