If you are in town and protesting NATO... by BruisedGhostin chicago

[–]mrestko 6 points7 points ago

Thank you for contributing a voice of reason. I don't think that most protesters actually know what they'll be protesting against. For many, it's more of an identity-building activity.

Decent gyms in Rogers Park? by 2-24in chicago

[–]mrestko 0 points1 point ago

Did you end up finding a gym you like? I was about to post this same question but I thought I should do a search first. I live by the Loyola campus and I'm looking for a cheap gym with free weights. Any luck?

That happened to me but after trying to get it fixed for over a week I just gave up and reinstalled. Just for my reference, do you have any pointers on where to start if that happens again?

What do you use to protect you from the sun? by sorryforhatingin simpleliving

[–]mrestko 0 points1 point ago

No one, not even those crusty biochem professors would dispute that there are other carcinogenic chemicals present in our environment, but those are the two things (uv radidation and the cocktail of toxins from cigarette smoke) that dramatically increase cancer rates above baseline. Most other substances that are considered carcinogenic are either uncommon for normal people to be exposed to, or cause such a slight rise in cancers that they are not worth stressing about. But, you're right, we have a ways to go towards cataloging the toxicology of all the worlds chemicals.

What harmful effects of sunscreen are you worried about? I studied biochemistry in college and several professor handed out this useful tidbit: The only carcinogenic things to worry about are smoking and sunburn, all the rest is minor.

WTF Should I do with these? by lastangrymanin food

Buy a box of latex or nitrile gloves.

MRI "testing". Expensive toy to mess with. by hasslefreein EngineeringPorn

I assume this was going to be decommissioned or something, but the number of people laughing in the background sort of makes this sound like a bunch of buzzed coworkers misbehaving after the Christmas party.

Probably not the trouble of digging them up.

The typography on this is so goddamn awful it makes my eyes hurt.

My friend joined a wireless network called Carrotnet. This happened right after.. Troll level: Master by simply_shreddedin funny

Your friend really shouldn't be connecting to Facebook without HTTPS, especially on open WiFi.

How are cartoon figures like this generated? (FYI it's a glucokinase) by NeutralRhomboidin Biochemistry

[–]mrestko 3 points4 points ago

Something like this software package: http://qutemol.sourceforge.net/

Although that hasn't been updated in a long time--I'm sure there is a more-modern visualizer out there with crisper graphics.

A word about positive intervention at the gym. by smokejaguarin Fitness

That sounds like something that would happen in one of Adam Sandler's early-era movies.

Statistical summary of 32.6 million plaintext passwords by arex1337in netsec

[–]mrestko 15 points16 points ago

I hate when sites silently truncate passwords when they're set, but then later when you try to log-in, they accept an arbitrary length. It makes no sense and it's incredibly frustrating, especially when using a password manager.

That's what the number is used for, but the "soft limit" can accurately be described as a sanity check--at least by my reading of the linked article.

Who's your carrier? Maybe I can get T-Mobile to lower my rates.

I have no idea what you mean by "salted, but not hashed".

Salting is when you append a known value to a password before hashing it in order to increase the work an attacker has to to when trying to brute-force hashed passwords. To "salt, but not hash" would presumably mean storing a salt value alongside an unhashed password. I can't conceive of a reason anyone would do that.

Hashing is an irreversible process that turns the password into a fixed-length hash. It can't be undone other than by hashing all possible passwords and comparing the output to the known hash.

Encryption is when a reversible process where the plaintext, in this case a password, is changed in a complicated way that depends on a key. The output, however, along with the key can be used to recover the plaintext password.

What Sony is saying in that press release is that the passwords were hashed, not encrypted. That is the standard, recommended way of storing passwords, it's not necessary, or desirable for the server to be able to recover the plaintext password.

It would make sense for something to be hashed, but not salted. This would indicate that the passwords were not hashed with a salt, and it would make a brute-force attack easier. It does not, however, make sense to say that something is salted, but not hashed. Unless you're talking about a potato.

I don't know what you mean by that. Do you know what you mean?

Ehh, SSLStrip would only work if I didn't type https://facebook.com into my browser. I know not everyone looks for that, but it's still pretty secure if you actually pay attention. I'm sure you'd be able to get some takers if you mounted an attack at a busy Starbucks.

Oh I know, but I'm also locked into a contract, maybe I'll switch at the end, it all depends on how much I want to use my upgrade credit once my N1 dies.
