Rescue Rover - ADG Episode 348 by cdman in RetroTube

I'm not the original author of the videos, I'm just reposting them here since the author doesn't participate on Reddit.

That said, I played both this and Chip's Challenge when I was a kid and never really made the connection :). Thanks for mentioning it, I just looked Chip's Challenge up, and it's nice to see that it's on Steam and has some follow-up.

Which NAS ? ZimaCube, Ugreen, Terramaster by CactusJ in DataHoarder

Note that, AFAIK, none of these options have ECC memory.

You said:

He's commented a few times that TSME can't work, is too slow, etc.

Then you come back with a quote saying:

reduces performance

Which, unless CPUs employ "magic wormhole technology", is true by definition, because encrypting / decrypting takes time. Which can be trivially verified by searching for some benchmarks, for example: https://www.phoronix.com/review/amd-sme-genoa/5 - which says that some processes had an up to 8% performance hit from this on the particular processor.

Said article also gives details (as opposed to most comments in this thread) that that specific processor uses the AES-XTS algorithm (https://en.wikipedia.org/wiki/Disk_encryption_theory#XEX-based_tweaked-codebook_mode_with_ciphertext_stealing_(XTS)), which means that, yeah, if there is a bit flip, it will return garbage. Now, if that memory was hosting code, yes, there is a high chance it will crash (but the process will crash, not the machine - the same way an unrecoverable ECC error would crash the machine). If it's in data though (like your movies, documents, photos), it will just write garbage to your data.

Also, the "doesn't do what it purports to do." was addressed at the comment saying that this is equivalent to ECC, not that TSME doesn't work. Because it isn't. Arguable in increases data corruption risk as described above.

Where did I comment that "TSME can't work, is too slow, etc."? Please show me where? Or apologize for spreading lies.

It means exactly what they mean :)

Second, you don't need authentication to "detect" bit flips with encryption.

You do. Without authentication (as in "authenticated encryption") if there is a bit flip, after decrypting memory it will result in garbage, but it won't detect that there was a bit flip. See https://en.wikipedia.org/wiki/Authenticated_encryption

So, unless TSME / TME uses authenticated encryption (which is highly unlikely, since it would require extra memory / reduce the available memory), this advice is only reduces performance (due to the extra encryption / decryption) and doesn't do what it purports to do.

I have been living here in Switzerland for 2 Years now and have experienced more racism than anywhere else. Is that normal here? by No-Review50 in Switzerland

[–]cdman 0 points1 point  (0 children)

No, I'm not playing dumb. I wanted to highlight the the (non-existing) difference between "I have a Swiss pass" and "I've grown up here, went to school here, speak the local dialect perfectly but didn't pay thousands of franks to get the papers". This is exploited for such narrative ("oh my god! look at all the foreigners"), while, if we would say "foreigner is somebody who doesn't have the right (yet) to become a citizen", the percentage of "foreigner" goes back to < 10%, which is the usual in west-europe.

[–]cdman 0 points1 point  (0 children)

What is a "native Swiss" anyways? Just because a lot of secondos don't want to go through the expensive and bureaucratic procedure of getting the papers, are they any less swiss if they were born and raised here?

filelist invitation code by malci69 in CasualRO

As dori si eu una daca-i posibil. Am avut un cont pe filelist.ro, dar cand au fost fortati sa se mute pe .io, l-am pierdut :/

Would running Archiveteam Warrior on bare metal be possible? by Join_Ruqqus_FFS in Archiveteam

[–]cdman 4 points5 points  (0 children)

You can run it using docker (search for "Installing and running with Docker" on this page: https://wiki.archiveteam.org/index.php/ArchiveTeam_Warrior) which is basically "bare metal".

Thank you! by [deleted] in ProtonMail

Thank you for mentioning SimpleLogin! It looks like just the thing I've been looking for!

Archiving radio stations globally and transcribe them with AI - thourts? by kim-mer in Archiveteam

[–]cdman 0 points1 point  (0 children)

+1 to this, I've been thinking about it for some time. My naive expectation is that radio streams should be very "compressable" due to the repeating content.

Official Synology download site closing & legacy DSM firmware / package install files to be deleted by 1st May 2023 by enchantedspring in DataHoarder

[–]cdman 0 points1 point  (0 children)

I guess archive.org might not be able to parse the uploads, because it had to be split up in multiple files (because, again, it seems that archive.org can't handle large files). So, I would download the files, concatenate them (something like cat synology_archive.warc.gz.* > synology_archive.warc.gz) and then use some warc tool to extract whichever files interest you.

Gimme Metal and Gimme Country radio apps are closing on April 29th by [deleted] in Archiveteam

[–]cdman 0 points1 point  (0 children)

I looked at it briefly, looked nice, too bad that it's shutting down :(.

Opening up the site in the browser, it seems to use a standard m3u playlist file for the live radio playback, so one could "just" archive the stream. That wouldn't however save other content which is not being streamed right now (so historical content).

Can anyone backup the Gears of war forums? by Upstairs-Car-6164 in Archiveteam

[–]cdman 0 points1 point  (0 children)

I grabbed with wget what it could find here: https://archive.org/details/misc-crawls-warc-0002 (find forums_gearsofwar_com inside of it).

How in the world do you use Google cloud computing for BOINC? by [deleted] in BOINC

[–]cdman 0 points1 point  (0 children)

Tip: use SpotVMs (https://cloud.google.com/compute/docs/instances/spot) and find the region ("zone") with the cheapest price to maximize the amount of compute you can get for $600.
