I'm a professional game developer (mainly programmer). I do Java and, when I have to, ActionScript 3. I also know PHP very well (Zend certified), but I avoid it if possible.

In my free time I co-run and develop for Revora Creative Network, a collection of sites hosting and providing services to creative projects (mostly game mods and indie games).

My UUID is:

comment Calculating the time required to brute force a random code
I just thought about it again, and you're right, it doesn't matter. Doesn't feel right though. :p

comment Calculating the time required to brute force a random code
But, how can that not matter? As an analogy, take a beach littered with a few soda cans (distributed uniformly). If you sweep the beach from one end to the middle, you're bound to have picked up at least 1 can. But if you just grab in the sand at random locations, the chance of that is much, much lower, right?

comment Calculating the time required to brute force a random code
The codes are distributed uniformly, so if the keyspace is searched in order, not randomly, the probability of having found a code after having traversed half the space seems to me to be closer to 100% than 50%. That's just a guesstimate, but an educated one. Assuming amount is a decent number and not 1 or 2.

comment Will Let's Encrypt allow a custom workflow?
@raz The tool will among other things automatically make a special file available on the web server. It can't do that if it doesn't understand the web server I'm running, so I'll have to do that myself, then tell the CA I've done it.

comment Detecting skimmers and other ATM traps
So, does that still depend on the magstrip to work? Meaning, could one make his own card safe by disabling/blocking the magstrip?

comment Detecting skimmers and other ATM traps
None of the answers here mention it (and maybe it's out of scope), but aren't they battling this phenomenon by leaving out the magnetic strip from new cards, leaving them with only a smart chip that can't be copied?

comment Can robots.txt for your face be made effective?
"As an added precaution, Superman would vibrate his face slightly so that photographs would only show his features as a blur" - Maybe this is an option to consider? :P

comment Why are hash functions one way? If I know the algorithm, why can't I calculate the input from it?
"it often doesn't matter if you get the same password or if you get a different password" - But it does when the input is not fully arbitrary but must fulfill some requirement, such as a password + known salt, or a message in a certain protocol. This makes the data-destroying aspect of hashes beneficial to security. (Of course, if you try long enough you can find an input that does follow the requirements, but that takes even longer)

comment Internal SSL Certificates?
If you configure the code to ignore any SSL warnings, you lose the authentication part of SSL. You don't if you manually install the trusted certificates.

comment Internal SSL Certificates?
@AdamTannon Almost, OpenSSL is not a CA, but the tool that you use to create certificates, whether with a CA or not. When compared with passports, CA = Government, OpenSSL = Printer
