Found Deals and Discounts / Re: Black Friday / Cyber Monday 2018

I guess it's that time of year again, twitter and mailboxes are starting to fill up with black friday/cyber monday deals, and we usually try to have an aggregate thread going. Here are a few to kick things off:

For anyone interested, the SpiderOak One unlimited account (which they said would never happen again) is back for a week. Of course it costs $30/year more than last time, so I guess it's not technically the same offer.

If you consider this, please keep in mind that unlimited space means lots of space subject to certain restrictions, see here.

(Disclaimer: I am using an unlimited account from last time they had this offer, and am quite happy with it.)

Didn't know they had started selling their office suite on a subscription basis. I hope they keep the option of buying a standalone version.

N.A.N.Y. 2019 / Re: This is an entry for NANY 2019 - SCrypt

f0dder's comments may be a bit direct, but try to take them as constructive criticism.

Writing your own encryption is a great project, but when you make it available for other people to use, it becomes important to be clear about the level of security. This is because a false sense of security is worse than no security. Imagine a person who downloads your program, encrypts all his banking information using it and sends them over email.

Cryptography is hard, and even seasoned programmers sometimes fall for Schneier's Law. That is why it takes years of public scrutiny and analysis for any algorithm to be widely accepted.

And even if you use algorithms generally accepted to be secure, there are details surrounding their use and combination that can compromise the security (like using an insecure source of randomness, storing plain password hashes, or using a block cipher in ECB mode).

Please note again that I am not saying you shouldn't continue working on your project -- I think it is great you wrote this and chose to make it available for NANY! Just make sure potential users are aware of it if you came up with your own encryption algorithm, and know whether the goal is to keep their family members or professional cryptographers from being able to read the file.

On a side note, there is a key derivation algorithm called scrypt.

Sometimes I've simply had my phone in my pocket while out taking pictures, and then went to Google location history (think it's called timeline now), which automatically tracks your movements, and exported the data and imported it into Lightroom.

I haven't done that for about a year or two though, so I don't know if this is still possible.

It is, I mentioned it above, but it's not as accurate as something that logs GPS co-ordinates, (program or device).

Oh sorry, I totally missed that!
