Q: Simplification of similar Python functions

@EthanBierlein MAIN, obviously.

Ethan Bierlein

No, I think it's actually MAINMAINMAIN, not MAIN. :P

int MAINMAINMAIN(int argc, char* argv)

A short time ago, I discovered the LinuxFromScratch project. After getting a system up and working (after much struggling), I realized that if I wanted to continue using LFS, some sort of package management would be quite nice. Of course I could have installed Pacman, apt-get, rpm, etc. like any ...

Q: Pretty print dice faces from multiple rolls of multi-sided dices

In this question related to rolling multiple dices, the OP pretty prints for a single case where number of dices is less than or equal to 6. This led to me finding this code golf on "Draw dice result in ASCII", but still only 6 sides. I wanted to extend this to at least 20 sides, and possibly so...

Perhaps this is better for CodeReview instead of SO. Also, it would greatly help to learn how to avoid .Select. Use the Macro Recorder to do some easy, medium, and "hard" things in Excel and review the code to see how it works. — BruceWayne 51 secs ago

Thanks so much, guys! I'll ask on code review and will now start reviewing your suggestions. Really appreciate it! — frankslivingmodel 25 secs ago

possible answer invalidation by Loki Astari on question by Loki Astari: codereview.stackexchange.com/posts/111268/revisions

@Duga yeah, right

4:41 PM

@Duga why is he posting a private key? :S

@DanPantry I thought it was his public key?

@Zak ~/.ssh/id_rsa.pub is public.

@LokiAstari you didn't "fail" - the command looks pretty simple.. it's just me, I've never bashed or pythoned or ssh'd.. you got me curious though, and I'm probably going to try and find a bash thing to download that's not hosted on sourceforge over the weekend :)

Public keys generally start with ssh-rsa .... (if RSA).

Sorry for the confusion.

I decided to use the Mods as my test subjects (but only the ones with publicly available github keys). Basically I used the script to encrypt a message using your github key and wanted to verify you could decrypt it. The Messages is encoded in base64 and wrapped in a function to decode it. That way it can be pasted directly into e-mail or a slack channel and the recipiant code de-code by just cutting and pasting into a terminal.

Your message was:

# Execute the following command to decrypt the file

4:43 PM

For example, this is my public key:

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCgaEXJUAvfcVylFkU0u23qSF3wgp2SKq4Z3h/bRnpr3SgvD+TjL+0vGbtb89Vp5USDmXcIiBmcgqNkifWqgXzWgN89jlZONVBiwvcQukFafoE8lJw10GgXRbypUt9/XVihhL6i8veYBFgws85loqDt/j03YSHCMbo+as9mUn2XCNe7K5s8k0KgkuO7RCwBblDfe2Msw9dXs43Ysbr8QHGwT29W5ksBU2sAuOXgN0vQ8Vtm88ixAf8FfDGaCgks7M7/wXLDYtJN4n6nm13j+movihbpVVjB4v0jrOzHpJ6Yqw88RkXZ9nC30q2j36g4NCn3iQ9iYMJpQ2GR9sFhC4oz dan@lambdaexpression.io

but cat ~/.ssh/id_rsa will show you the private key by default

@LokiAstari Why do you want to do this in the first place? Which keys do you want to swap? The public keys are already public, and the private keys shouldn't leave your computer...

I don't want to swap. I want an easy way to find people's public key. So I encrypt messages to them (github provides you public key). Only they can decode the message on the other end as only they have the private version of the key.

I defnately don't want people sending their private keys anywhere.

The first line of your post is: wRecently needed to swap keys with a colleague on the other side of the country.

@LokiAstari $ cat ~/.ssh/id_rsa.pub?

@holroy: O. We needed to use some shared keys for a system.

4:49 PM

i would be wary about installing a program that had access to my .ssh folder at all, though, tbh

s/installing/using

I had a copy of the shared key my collegue did not. I did not want to send the keys across a non secure channel unencrypted.

And why are you generating new keys, since you need to replace ssh-keygen?

I want to congratulate you for not going the using namespace std route. It's a mistake many beginners make because they don't know any better and you went for safety instead of laziness. You say you're not sure which of your includes you actually need. These are the ones necessary to run: #incl...

java algorithm graph breadth-first-search

@holroy Now I could have set up a machine. Put his public key on that machine and placed the secret on that machine so he could then log in and retrieve the secret. But that seemed a lot of work (maybe OK if we did it once). But its not a highly repeatable or easy to automate.s

So I wanted an easy (secure) way of distributing secret information. Where all I need is your public key to start the processes (If my colleague is in a different time zone and our work hours don't overlap getting the public key the first time is a pain (then I have to manage the public keys)). Just seemed simpler to use a set of publicly available "Public Keys" to generate a private message.

Q: Graph radius in Java

The following snippet is a brute-force algorithm for computing a graph radius in time \$\Theta(V^2 + VE)\$ and space \$\Theta(V)\$ simply by doing \$|V|\$ breadth-first searches over each node in the graph. The graph radius is a minimum graph eccentricity of any node of the graph, where eccentric...

@Mast might earn you a [badge:reversal]!

Mast

@Mat'sMug It still needs 18 more votes to get there, I'm not sure it's that good.

But hey, I've seen stranger things happen and a Reversal badge definitely wouldn't hurt.

wah, hadn't realized that badge was so hard to get

@LokiAstari If you have my public key, you could use that to send me secret messages over the open internet. That is the main point of encryption. And to verify it's from you could sign it using your public key... If he doesn't have access to your public key, then you might have a little handshaking to be done, but I still can't the reasoning behind your script. But I leave you to it...

Mast

It's gold with a reason ^^

@holroy The intent of the script has nothing to do with the keys used.

@holroy The point was to show that you can use github as the source of public keys (you don't need to manage the keys yourself). I don't need to have your public key, I can get it from github and encrypt the message without having to ask you for your public key (which can waste upto a day getting the public key). The rest of the script is just using the public key and standard openssl commands to do the encryption de-cryption.

@holroy The other point of the script was rather than the recipient having to remember how to decode the message (or doing a 30 minuite google on how to use openssl). Was just to provide it as a script that he can cut and paste to get the message.

@holroy None of this is special or unique. I just wanted to make the processes as trivial as possible (I just strung the already available tools together).
