- Comment on Press a button and this SSD will self-destruct with all your data 6 days ago:
if you’re using proper encryption it’s going to be difficult or impossible to decrypt the files on the drive, so the data should be secure even if the drive is stolen, copied, etc.
Encryption should always be the last line of defence, encryption that is unbreakable today may be trivially broken tomorrow. Which is why I also I still prefer to overwrite drives with random data instead of just trusting the sanitise command (Even though I know that a big chunk of the data stays unoverwritten as part of the drive’s “provisional area”.
(Which raises another issue that “deleting” a luks keyslot or the whole header doesn’t actually warranty it’s deleted, may have just be moved to the provisional area. So if a key somehow is compromised it becomes nessesary to physically destroy the drive.)
However, when you’re actively using the drive and have files decrypted, and then you lose physical access to your devices, you have a problem. IIRC that’s how they got Ross Ulbricht’s files - monitored him until he unlocked his laptop in a cafe and then grabbed it (and him). If you’re worried about that specific threat profile it makes a little more sense to have an easily accessible physical DELETE EVERYTHING NOW button that only operates when the drive is running.
In that case I rather use something that will reboot the computer and shred the ram as it would serve the same purpose with the bonus that contents can’t also be recovered from ram. Something like an usb drive with a string wrapped around the wrist.
Now, in the situation that the keys have leaked somehow, (like recording the keyboard from afar while the user types the passphrase) then the self-erasing hard drive makes a lot more sense, assuming the user has time to trigger the mechanism.
Now the issue is, that overwriting even a fast ssd takes time, so I’m assuming the device works by destroying or erasing a security chip that holds the keys for the main storage, however the data is still there if the adversary cuts the power before overwriting the whole drive. Ofc encrypted, but like I said before, encryption may be broken tomorrow. A physical or chemical solution that grinds or dissolves the chip somehow seems to me a better option, with the bonus that it can be made to work without electricity.
- Comment on Press a button and this SSD will self-destruct with all your data 6 days ago:
So, let’s see if I understand, the device only destroys the data after it’s connected to a computer.
So an adversary can just not connect it to a computer and extract the data through alternative means (like unsoldering the chip and reading it directly.
The device should be able to destroy itself either from an internal battery or some physical or chemical mechanism.
- Comment on Why do some people make such a big deal over ages of someone's account on here? 1 week ago:
I tend to abandon all my online accounts from time to time and make new ones for privacy reasons, and IMO everyone should do the same, together with using different names for every website.
Unfortunately the trend is for people using the same accounts that they made when they were 12 for the rest of their lives.
If people were more conscious about their privacy and pseudo-anonymity then I think there would be less bias against new accounts.
I haven’t seen this on lemmy, but on reddit there are whole communities that you can’t post if you don’t have an old account.
- Comment on How bad is it really to listen to music with headphones? My mother told me if I keep doing that I'd go deaf... Is that fearmongering? 1 week ago:
It’s a myth that headphones cause more ear damage than speakers.
95dBs measured at the eardrum are 95dBs independently if the source is 10m away or inside your ear canal.
Now most people tend to blast louder on headphones than they do on speakers, I tend to do the opposite, so in my case speakers cause more damage.
If you “just turn it high enough to hear it” then there’s no damage. In fact if you listened to speakers you would have to probably turn it louder to overcome the environment noise than you do on headphones that muffle outside noise.
Brb, posting dB chart (need to send the post and edit it latter or my phone kills the app when I switch apps)

- Comment on ISP tricked customers about fiber optics being used in their internet service, German court rules — 'full fiber' customers found to have 'last mile' copper connections 5 weeks ago:
I hate to be the one defending companies but this time I have to align with the ISPs.
As a “fake fiber” client myself, there’s virtually no performance difference between the two. But “fiber” has become such a marketing slang that most clients wouldn’t signup for an ISP if they don’t sell “fiber”.
Alternatively the ISP would have to replace perfectly functional infrastructures purely for the sake of marketing, resulting in waste.

- Comment on Is anyone NOT steaming their Music? 1 month ago:
Even tho i have a several TBs library I still stream, because I always went to find and listen to new things that aren’t in my library.
Generally if something is on my library, I’m already tired of it.
So I endup streaming from YouTube music free + unlock origin. If I want to listen to a whole album without having half of it’s songs replaced by a low fidelity music video version I open the album link with mpv or listen to the album from telegram bots like @deezload2bot or @linemusicbot
- Comment on How do I stop sleeping through everything? 1 month ago:
Have you tried getting a louder alarm clock?
Like plug your phone to a powerful speaker system that reaches 100dB. That should wake everyone.
Doesn’t have to be expensive or HiFi, just loud.
May not be an option if you have neighbours tho.
- Comment on Is Star Trek Discovery that bad? 2 months ago:
Discovery is my least preferred star trek I’ve watched so far, I mean, it’s not “bad” per se, it’s just different from the rest of star trek and has a different formula.
The thing with discovery is that everything happens really fast, there’s always a sense of urgency and hurry, but actual plot development happens really slowly.
Conflict takes a whole season to resolve, instead of standard one episode which you expect from a star trek show.
Also, I hate how the actors mumble instead of talking.
It’s not bad, it’s just not my favourite format.

- Comment on Samsung phones embedded with 'unremovable' Israeli spyware 2 months ago:
That website is an excellent resource, but they can’t just expect everyone to have money for a pixel, even if privacy is a priority for me and many people, a pixel is just beyond the reach of the large majority of internet users.
Instead they need to make a curated list of less than ideal but still better than stock alternatives, or else people will just give up and get stock android instead.

- Comment on 'Star Trek: Strange New Worlds' & 'Doctor Who' Crossover? Watch Finale Sneak Peek 2 months ago:
The overall lore is that humans in the future build empires and enslave several species like the ood.
Humans conquer planets and dry all it’s resources with no regards for native life, they drain the swap and enslave the swamp people to mine toxic minerals.
Companies are all powerful, and the government extremely corrupt.
- Comment on 'Star Trek: Strange New Worlds' & 'Doctor Who' Crossover? Watch Finale Sneak Peek 2 months ago:
There are many ways they could make it match, they could pass it as a parallel universe somehow, or maybe make some god from the pantheon of discord together with some Q bridge the worlds.
I always found quite funny how Doctor Who’s universe is much darker than Star Trek. Doctor Who’s universe is more akin to Star Trek’s mirror universe where are human empires that enslave smaller planets, while on Star Trek there’s the federation and all.

- Comment on [deleted] 3 months ago:
If you are speaking about soundproofing I’m assuming you live in an apartment and have neighbours, I will be making my recommendations based in that assumption.
Also, note that I value audio quality more than video, so if I have a limited budget to setup a home cinema most of it will go to the audio.
For home cinema surround systems are usually the standard, however in my personal and subjective opinion surround adds much to the cost without really proving much value to the experience.
Cheap surround systems like those trendy soundbars will sound like shit comparable to a stereo system for the same price. Yes, they come with a subwoofer so they have bass and provide that wow factor, but you may notice it to be unbalanced the middle or upper frequencies to lack clarity.
If you have a small room and plan on watching films just yourself (and maybe an occasional friend)I recommend a setup similar to mine, a small LCD TV (32" or a bit bigger) and a pair of 8" studio monitors.
From my understanding cheap projectors have quite a substandard image quality and brightness, I understand that you prefer a projector for easier transport, but a small TV is also easy to carry it, you can literally carry it in the backsit of a small car. And will look much better than a cheap projector.
So with your given budget you can get a quality TV for about 500 dollars and a quality pair of near field speakers for another 500 dollars.
This is the perfect setup for a single person intimate setup, however fails short when you put multiple people in the room.
However if you have a big room with many people on it then you will need to compromise on quality, a bigger screen, maybe a projector and maybe a pair of loud used pair of HiFi speakers, since studio monitors aren’t really meant to fill the room and 32" TV will look tiny from a sofa.

The issue with hard drives is that they tend to fail even on ideal conditions and even when powered down. Yes I’ve lost very important data to a powered down hard drive.
While it’s possible to recover information on a hard drive as long as the plates themselves aren’t damaged, that requires very expensive specialised tools and skills. Which probably wouldn’t be available in a scenario where the information on the drive would be of any value.
DVD-R (and probably consequentially Blu-Rays) aren’t any better in my experience, I’ve lost more data to DVD-R than to hard drives actually. Even when stored in low light conditions they tend to just stop reading.
However optical media has one big advantage here, is that the discs themselves are cheap, so instead of having all your digital eggs in the same basket, you spread them over several discs and while some information may be lost, others may survive.
Now, here’s an interesting thought, with digital data, the data either reads or doesn’t read, the so called digital cliff, may become partially corrupted and other parts still read, but after the corruption gets past a certain threshold all information is lost.
With analogue equipment even after severe signal degradation the contents while very deteriorated may still be perceptible, forwardermore an analogue signal is much easier to decode in the event that you need to restart
civilisationbuilding tech from scratch and don’t have access to the very very specific specifications of something like the audio codec or the filesystem.You can probably hack a rudimentary cassette player together from very simple components, all you need is a tape head (a coil), a motor (a coil and a magnet), and an amplifier (a transistor or vaccum tube). (I’m probably oversimplifying here).
Overall I think the most important thing is having redundancy, or if redundancy isn’t possible at least don’t have all eggs in the same basket, instead of having everything in a single 8TB HDD, to try spread them into smaller 512GB ones, or DVDs or flash drives or all of the above. And don’t store them all in the same location, if an area gets flooded or someone builds a building on top, you’re only losing a small part of the information.

I can’t think of many things you can buy for a dollar, maybe a bottle of water and 2 pieces of bread.
Chewing gum maybe, back in the days those were cheap, doubt that’s still the case.
Photocopies, those are cheap, you can get like 7 copies with 1 dollar.
Can’t think of anything else, really.
Also earning more? That’s not possible, unless you’re willing to beg, but then that’s completely unrelated to your initial dollar.

Anime is very poorly mixed, a phone vibrates as loud as an explosion, there’s no dynamics. That’s not how real sound is supposed do work.
I agree that some shows like modern Star Trek exaggerate and while I can’t hear Michael murmuring the Spore Drive almost blows my woofers away every time Discovery jumps.
However needs needs to have dynamics so the viewer can have an emercive experience.
- Comment on Off topic 3 months ago:
They should release dual audio, high dynamic range for ppl with good systems and low dynamics for ppl listening on computer speakers, but if that’s not the case I can always put a compressor on an HDR master, but can’t recover lost information on stuff like anime where a phone vibrates as loud as an explosion.
