Hey @tylerl.

tylerl

@TerryChia sup

Terry Chia

@tylerl Do you know anyone on the GAE team? :)

tylerl

6:28 AM

@TerryChia google apps for enterprise, you mean?

yeah, quite a few.

thats who I spend my day-to-day with.

or you mean app engine?

(I know fewer of those)

Terry Chia

@tylerl App engine. :)

tylerl

but I know how to get in touch with them.

Terry Chia

Was wondering if I can get github.com/pyca/cryptography on the approved modules list.

They have PyCrypto but that's a mostly dead project now.

tylerl

does it use native code?

Terry Chia

@tylerl Yes. OpenSSL.

tylerl

6:31 AM

does appengine have openssl?

cause that's just a shared lib

yeah -- cloud.google.com/appengine/docs/python/sockets/ssl_support

you just gotta declare that you're using it and its available

Terry Chia

@tylerl I thought the only Python modules you can use are the ones listed here? cloud.google.com/appengine/docs/python/tools/libraries27

tylerl

you can bring your own modules

thats just the list of modules they provide.

but there's nothing stopping you from installing modules as if they were part of your own code inside your directory tree

the only catch is that you can't use native code.

afaik

Terry Chia

@tylerl Hmm, that may be a problem then.

Because pyca/cryptography uses CFFI, which dynamically builds a C extension against the OpenSSL shared lib at install time.

tylerl

so it's not using pyopenssl to link to openssl

Terry Chia

@tylerl Oh no, in fact pyopenssl is the downstream of the pyca/cryptography project.

tylerl

6:41 AM

whats the use case where having it is important?

Terry Chia

@tylerl For me basically having an actively developed crypto library available.

tylerl

I could put in a feature request, but they take the security of the appengine platform pretty seriously, so stuff has to be properly reviewed and vetted and stuff, so you gotta have a good enough reason to convince someone to put in on their priority list.

Terry Chia

@tylerl Well, PyCrypto (which they have available currently) hasn't been in active development for a long time now and the maintainer has been in discussions with us to merge the projects.

A lot of the Python ecosystem is now starting to use pyca/cryptography so it will be nice to have it available on GAE as well.

tylerl

@TerryChia If that happens, then adding support for your project would essentially be rolled in to updating the pycrypto project?

Terry Chia

@tylerl The idea currently is for PyCrypto to use us for their backend instead of their custom C code so projects relying on PyCrypto's API can still continue using it. Meanwhile we have our own (much nicer imo) API that many newer projects are using. The talks are still very early-stage but it looks like it's gonna happen since the current maintainer appears to be very tired of updating the project.

I'm not sure how the GAE team works; as an end user I just want to use my library on GAE. :P

Not a big deal but hey, since you are a Googler I thought I'd ask. :)

Q: Is this new flat theme mandatory or is there an option to change it back?

I noticed today that Stack Overflow has changed to a more flat UI. I have nothing against flat UIs, but I am used to the old theme and it is more visually appealing to me. Is there an option to switch between the old design and the new one?

I see that SE users are not exempt from complaining about any design changes to their favorite website.

I don't get the issue. I generally don't notice updates to themes on websites, because to me it is like advertising: Irrelevant. All I'm interested in is content.

Face the nation is on. Everyone is blathering on about surveillance and I'm just sitting here wondering if I'll have a career

tylerl

@TerryChia I don't visit SO very often, so when I saw it was different a couple of days ago, I just thought there was something broken about the browser/cache/display driver, or something.

The new theme looks like the page had been printed out and scanned back in on poor-quality equipment.

@kalina I'm here now and then. Just not quite so much as I used to be. Work's been killer lately.

CodesInChaos

@TerryChia I don't like the new font (or more precisely, how it's rendered on windows). The kerning is bad, there is often no space at all between characters.

I don't care too much about the design itself, but readability matters.

Q: How to do Rijndael MixColumns step ? Plz Help?

am trying to go through all of the the steps in the Rijndael Encryption Algorithm ... when i multiply of a value by (02) , what if the leftmost bit of the original value (before the shift) is 0 not 1 ??

cryptography aes

0

Q: AES MixColumns step ? pleas help

{d4}.{02} = 1101 0100 << 1 (<< is left shift, 1 is the number of shift done, pad on with 0's) = 1010 1000 XOR 0001 1011 (because the leftmost is a 1 before shift) ans = 1011 0011 now what about : {5d}.{02} witch 5d=01011101 here the lift most is not (1) .. how it's done ??

I'm not gonna comment on how great dane tag would be

@TildalWave I don't think we need tags for different nationalities, not even Danes.

@CodesInChaos there's flags for that :)

@RoryAlsop Did you get to see the comet? Also the Venus and Mercury are pretty close and Mars and Neptune

Last night was brilliant. Temperature dropped right down, clear night, best stargazing for agrees. Thought I was going to have to show the kids by navigating from Rigel and Aldebaran, but it was clear enough that the Pleiades were bright to the baked eye

Naked, even

@RoryAlsop nice typo :op

Typos! s/agrees/ages ... @RoryAlsop did you lie in your auto-correct settings how old you are?? :)))
