Neither. It's about using screen pixels to make vertical/horizontal lines, using aliasing as feature.

 
 

Based on other similar recordings I made, I estimate it at 4GiB.

It was a baseband recording of APT+DSB from the NOAA-15 satellite from when it had AVHRR scan motor issues. Not that rare for NOAA-15 (xD), but now that the satellite has been decommissioned, I'll never record it again.

I do have baseband recordings from good NOAA-15 and 18 passes, but still, this one would have been special.
I've posted about it when the issue was occuring: https://lemmy.sdf.org/post/3035683
Alternative link: https://lemmy.world/post/4162384 (preferred - our instance is slow - trying without cache a few hours ago, loading main page took 2 minutes and 12 seconds excluding loading of thumbnails)

I've just been looking into this again yesterday, and remembered that at some point I had a recording of this partial failure, but it seems I permanently deleted it. The last place it could have been, a HDD from my old laptop, I wiped 2 months ago (incl. full overwrite).

At least I still have the demodulated audio of the APT signal from that partial failure - keep in mind this was still analog - NOAA-15 launched in 1998.


Perhaps not the usual file with sentimental value, like picture or video, but I am a bit weird. I can never record it again. Fuck, I need to start archiving everything.
Now I feel like BBC, erasing TV shows to re-use the tapes.
Or perhaps more aptly (pun intended), NASA re-using Apollo 11 landing imagery tapes.

Oh, guess where I had the 2 remaining recordings. On the cheapest unbranded DVDs I bought on sale in Kaufland at 10 cents / disc, which seem to corrupt after 4 years and can split apart easily with fingers.

I do that physically. The undo attempt. (Usually doesn't work)

It's edited or AI based on another image.

Alright, so others went over the "easy" way to see which program is being the offender. But I feel like the average Lemmy user just skips GUI at this point.
Say hello to KDE:

KDE also does automatic fsck before mounting, which is why it may take some 2 seconds to mount a drive.

HDDs it properly spins down and unpowers as well.

Writes are asynchronous on Linux.

Unless I mount it with sync, which I wish would be default for non-system drives (which are going to be in fstab anyway). I didn't notice any difference, aside from the lack of guessing when the magic is over. 2GiB goes into black hole, now what?

  1. You can also... left.

Well, Wikipedia: https://en.wikipedia.org/wiki/DVD_region_code#Computer_DVD_drives

Basically same as regions on standalone DVD players. Just a scummy thing to only allow you to play DVDs from your own region, perhaps so that you wouldn't buy them from cheaper countries, or buy them earlier than you're supposed to in your country.

If everything works correctly, then say you buy DVDs from UK, but something new just released in US, but haven't even played in cinemas in UK yet. So you buy it from US... and it shouldn't work.

VLC doesn't care about this, but still, the drive firmware might.

BluRays also have regions

By the fucking way, BluRays have some DRM with revocable keys

This is part of the AACS protection scheme: editors are able to revoke old software player host keys that have leaked on the Internet and distribute the lists on newer commercial disc releases. This is irreversible and cannot be fixed even after reflashing the drive.

https://wiki.archlinux.org/title/Blu-ray#Revoked_Host_key/certificate

So when do you truly own something? When you pirate it. No regions, no DRM, 4k on any device powerful enough.

[–] user224@lemmy.sdf.org 5 points 1 week ago

Except the problem seems to be the said storage device.

[–] user224@lemmy.sdf.org 11 points 1 week ago (2 children)

If it is a hardware failure, I don't see why it should be an issue. I know re-installing Windows is something PC repair shops do often, and I don't see how that's different from any other OS.

fault or failure resulting from software

Unfortunately, that's quite broad. But it could also just apply for stuff like overclocking or firmware modifications. Or even simpler stuff. I could see someone having DVDs from multiple regions, changing drive region every time until they hit the 5 changes limit, and then trying to claim it for warranty (I've had some software on Windows do that automatically...).

Should I submit it with the Linux installation intact or replace it a fresh install of Windows

Or if there's private data, overwrite it with output of /dev/urandom or /dev/zero. blkdiscard might also be your friend since it's an SSD.

I am doubtful whether they have experience working on anything other than Windows

Probably they'll just test the rest with their own drive or re-install it.

Or maybe try to ask them how to prepare the device for the warranty claim.

Welp, turns out I am just an idiot. 1279 and below disabled IPv6, and thus the ::/0 route didn't get applied either, causing a leak. What's still odd is the lower download speed that doesn't happen in another client.
As for the upload, it probably gets a better route through the VPS, giving me a faster speed, and giving me some confusion.

So my first idea with IPv6 was close, but on the other side of the connection.

Anyway, your reply helped me find this issue, as my outtake was to try fully disabling IPv6 (not the first time I tried such "solution").

I tried catbox, but that didn't embed, and our instance is too slow to host images.

Durning peak loads, I may wait up to 2 minutes to fully load lemmy.sdf.org.

Otherwise I'd avoid Imgur as I always get 403 with a VPN, and I basically always use one.

#include <stdio.h>
int main(){
step1:  /*Step 1*/ printf("Be attractive\n");
        /*Step 2*/ printf("Don't be unattractive\n");
        /*Step 3*/ goto step1;
}
 

OK, first of all, I am not a programmer. (yes, I heard the "thank god") Perhaps I could make the top example simpler.

But anyway, I kind of like goto too much. I find it more intuitive to just jump around and re-use parts rather than think about how to do loops without too much nesting.

In high school, we only did Python. I really wanted to do goto in Python as well, but all I found was this April fools' goto module.

Now in college we're starting with C, and I am starting with Bad Habits^TM^.

Anyway, tagging every line was BASICally just for the joke, but it is useful to just jump to any random line.

 
 

I am going to try not to write yet another wall of text

  • I was supposed to get 3 months 50% off after adding my student card to transport system that I've already been using

  • An employee told me it indeed doesn't really work and just gave me 3M 50% off code from some spreadsheet

  • I tried to activate it nearly a month later, at which point it had "expired"

  • I contacted tech support, they told me they don't know about such offer, nor there being any spreadsheets with discounts, and instead offered me 50% for 1 month (possibly from the friend referral program), or that they could try opening a case which may take 30 days (basically urging me to get that 1 month)

  • I went out again to find that one single very specific employee who knows what I am talking about. He gave me another code from the spreadsheet. I warned him that it's for 6M, not 3M. "Whatever, so you get 3 months more", he said smiling.

There goes unlimited data for EUR 10.25 / month.

 

I don't have a freezer on my dorm.

Probably because they were cheap (€2.59), and the thing seems to be mostly water, sugar and coconut oil.
Anyway...

 
 
 

The SWIPE plan of Slovak Telekom limited by age up to 28. Despite them having a web portal and shop, SWIPE can only be purchased and managed via a separate app for SWIPE.

Going through registration, it just loads a fucking website to do the registration.

But if that's not enough, it's Chrome-only it seems.

The support for SWIPE seems limited to an LLM chatbot that can do anything but being helpful

Furthermore, at school I got an ad for 3 months 50% off on this plan with ISIC, yet such an offer seems nowhere to be found on the internet, and I've been unable to find the code as directed.

This feels like a usual no-name brand scam, yet it's just part of Deutche Telekom group.

 

Above is basically same thing in Slovak

"How can I talk with a human?"

"Hello! You can talk with a human in person, through phone, or various chatting applications. If you want to contact someone through SMS or call, with our service SWIPE you'll manage it perfectly. If you have any specific question about SWIPE, feel free to ask!"
