Is there a 30% improvement in Time-to-Degradation from bad voltage management?
Maybe they shouldn't be using "Breakthrough Performance" in their ad copy...

Woah woah woah, this reads as a major scam...
> If you have an American Express or Discover card you can enter your online credentials we'll load your charge names directly to check them for fraud. Your credentials are transmitted securely and then cleared after querying. No personal information will be collected. Your card will never be charged.
Never ever ever ever do this. This is a terrible idea and if this is a legit site, they should never offer this as an option
This is 100% a scam site, please flag
I put in test/test as the creds and it claimed to query and start collecting the data
> Please wait while your report is being generated... > Parsing account information > Querying for transaction information > Parsing transaction information > Loading charge batch
Then I gave up waiting as my tracking blocking went crazy.

Fun game! Resizing the browser window after it starts breaks the game though. If you you resize it so the princess is off the screen, you can't lose :)

Yeah I came here thinking it was about books. Apparently Magic people call their cards a library? Here I am sat with a plain old deck of cards like a complete lemon.
In Magic parlance, you play the game with a deck, but all your cards that you can build decks out of is called your library.
Steve Ciarcia’s Byte magazine articles are a great read (in fact all of Byte was great) - being enthralled by them as a kid but not understanding them probably had a large effect on me choosing to study electronics.
From the comments on the archive.org details, that archive is missing years, the original source of the scans is http://vintageapple.org/byte , and it has all of them
Yes, but only if you have all three opened, i.e., you are in a "home alone scenario". Remember that Shufflecake volumes have a hierarchy, i.e. volume 1 is "less secret" than volume 2, which is "less secret" than volume 3, etc. In your example, during an interrogation, you would only open volume 1 and maybe volume 2, but not volume 3. You would see that volume 1 has 10 GB of data, volume 2 has 20 GB, and you can still write 70 GB before getting I/O errors. Nothing hints at the fact that there is a 3rd volume. Of course, in so doing, you will actually overwrite and corrupt volume 3, but this is desired behavior. That's why we recommend of always opening all volumes for the "home alone" scenario.
Thank you for that clarification.
Another question about this, presume #1 10 gb, #2 20 gb, #3 35 gb
We have #1 and #2 open, #3 is taking 50% of the 'free space' shown. Is writing data in #1 or #2 have a roughly 50% chance of destroying data in #3 or does it known mapped blocks and the overwrite only happens once the actual free amount is used up?
Thanks for the question! Well, overcommitment is part of the plausible deniability design: basically we need that, whatever password secrecy level you provide, it looks like all the disk space is utilized, because if there is clearly unmapped space then it's clear that there is still something hidden.
Currently, we achieve this with overcommitting the volume size: if you have, say, 1 GB device, and you format it with a 3-volume Shufflecake setup, each of these 3 volumes will appear as 1 GB in size. Then the question is, what happens if you write more than 1 GB in total? Well, you will start receiving I/O errors. Volumes themselves will not get corrupted, because they will not clobber each other, but the kernel module will basically tell you "sorry, I ran out of space earlier than I expected".
A planned feature in the future, to manage this more elegantly, is to use "virtual quotas". With this system, low-secrecy volumes will have a limited size (chosen by the user), but the "topmost" unlocked volume (the "most secret one" that you have unlocked with a given password) will not have this limit: it will always appear as taking all the leftover space. See the section 6.5 "Use of Disk Metadata" in the research paper.
Can you describe what you mean by plausible deniability if in your example you can prove from any of the individual Shufflecake volumes that there's X amount of data in the others?
3-volume Shufflecake setup with on a 100 gb device. I put 10 gigabytes into #1, 20 gigabytes in #2 and so in #3, I can only store 70 gb of data before I get I/O errors, which leaks that there's 30 gigabytes of data in the other volumes.

Matrix or Briar? Wouldn't P2P/self hosting always be better?
p2p leaks the 'metadata' of the network connections. It makes it trivial for someone to know that these two nodes are talking to each other. A goal of this, and other similar protocols, attempt to prevent that sort of metadata analysis.

Are you at all familiar with "Telegram Dude"? A fugitive of the Russian Government, an expat whose Facebook-like social network VKontakte was seized by the Russian Government, before he fled Russia and started an encrypted messaging app in response?
I'm no expert on his current activities, but this isn't a situation without Known Context.
there are news articles (I admit, of questionable origin) the claim he visited Russia yearly for the past decade. I do wonder if it the situation is a little more complex then he was a fugitive of the Russian Government
