I (Electrical + Software Engineer) once worked for a physicist who believed that anything less than an order of magnitude was merely an engineering problem. He was usually correct.

I was taught the same. To not care a lot about things under an order of magnitude. Over the years when planning large software projects or assessing incidents and so on, the 1 order of magnitude threshold helped me often.

Autocompleting secrets sounds unsafe. > The receiving side offers tab-completion on the codewords, so usually only a few characters must be typed.

I had the same reaction. It's a one time password, so it does not need to be as secure as a permanent one, but it still feels silly to have a long password that you can just type the first few characters and have it auto complete each word, versus just having a shorter password to begin with.

That said I can see how autocompleting from the first three letters of each word for "beaver-grass-hypocondriac-shelf" might be easier for a human than typing "beagrahypshe"

(magic-wormhole author here) Thanks for making a donation! I run the relay server, but the Debian maintainer agreed to bake an alternate hostname into the packaged versions (a CNAME for the same address that the upstream git code uses), so we could change it easily if the cost ever got to be a burden. It hasn't been a problem so far, it moves 10-15 TB per month, but shares a bandwidth pool with other servers I'm rent…

> move to a slower-but-flat-rate provider As I'm sure you're aware: https://www.scaleway.com/en/stardust-instances/ "up to 100Mbps" for $4/month

Contabo also might be an option: https://contabo.com/en/vps/

Throttling after 32 TB: https://help.contabo.com/en/support/solutions/articles/10300...

Some commentary: https://hostingrevelations.com/contabo-bandwidth-limit/

I wouldn't say that they're super dependable or that the VPSes are very performant, but for the most part they work and are affordable.

Alternatively, there's also Hetzner, as sibling comments mentioned: https://www.hetzner.com/cloud/

They do have additional fees, though:

> You’ll get at least 20 TB of inclusive traffic for cloud servers at EU and US locations and 1 TB in Singapore. For each additional TB, we charge € 1.00 in the EU and US, and € 7.40 in Singapore. (Prices excl. VAT)

I also used to use Time4VPS, however they have gradually been rising prices and the traffic I'd get before being throttled would be less than that of Contabo.

I use wormhole a lot, but I've been too lazy to figure out if it's as secure as ssh/scp, so I always gpg the file I'm transferring before putting it into wormhole. Is that paranoid behavior?

It can't hurt, but it shouldn't be necessary. The client-side software establishes an encrypted connection with its peer, using an encryption scheme that should be just as secure [but see below] as what GPG or SSH will give you. For GPG to add security, you also have to make sure the GPG key is transferred safely, which adds work to the transfer process. Either you're GPG-encrypting to a public key (which you must ha…

author here.. happy to answer any questions!

It absolutely isn't. See my rant: https://news.ycombinator.com/item?id=24519895

Maybe stay with wormhole https://redrocket.club/posts/croc/

Got fixed pretty thoroughly though, it seems! https://schollz.com/tinker/croc9/

I found this quite uncomfortable to read because of the complete lack of capitalisation - it's a very odd choice.

I don't think auto-completing a code-word leaks any information, since the set of code-words is fixed.

Just think of each word as being one character from a large-ish alphabet.

Code-words are used so that the one time secret can be easily remembered or shared over a voice channel.

Bingo, I studied Physics!
