FYI, it is possible to call Matplotlib in an 'object-oriented' way without global state; though it's a bit more cumbersome than just using the pylab interface. See http://matplotlib.org/examples/pylab_exa

Imagine that Keybase is compromised. It starts serving a password-prompt page that looks identical to the previous, but now sends your decrypted key straight to the malicious attacker. Storing your private key on Keybase allows Keybase to b

It's not correct that you need to trust Keybase. The way that someone verifies their social identity is by posting a tweet (or equivalent) signed with their private key. So you can look up someone's public key on Keybase and then

Naturally you have to "raise taxes" (in a nominal sense) at the same time you add a basic income, so that the added income is cancelled out for middle-class and wealthy people, and the net amount of redistribution stays more or le

The two major subsidies for cars are gas (which should cost several times its current US price) and parking (which is often provided free by businesses using otherwise-valuable real estate). Neither of those subsidies really apply to public

The naive total-arbitrated-BTC solution wouldn't work, since someone can always arbitrate a bunch of 'transactions' between sockpuppet addresses they themselves control. But as long as there's some mechanism to pay arbit

From the documentation: "Hyperopt has been designed to accommodate Bayesian optimization algorithms based on Gaussian processes and regression trees, but these are not currently implemented." [1] So it sounds like they've at

Yeah, that's probably a better general solution. That said, there are some contexts, e.g. working on academic research code which is always buggy, where you really do want debugger-on-exception to be the default behavior, so that you

My impression is that R and MATLAB (and Julia) certainly still have their advantages. But, Python with pandas/scikit-learn/matplotlib is almost as good at R at data munging and exploration, and with numpy/scipy/Cython,

There's a nice trick to enable this behavior for standard Python code run at the command line. Write the body of your code inside a main() function, then call it using the following toplevel block: if __name__ == "__main__&quo

K-means is simple, easy to implement and it often works quite well. It's unlikely to be state-of-the-art for any particular problem, but if you just need to do some straightforward clustering as part of a larger data-processing pipelin

They don't mean anything in particular. The actual analysis is being done in a high-dimensional space, in which each post is represented by a high-dimensional vector of the form [0,0,1,0,...., 0,1,0]. The length of the vector is the

My point is that you don't have to control the marketplace itself in order to create honeypot sellers. There was nothing stopping law enforcement from registering honeypot sellers on the original Silk Road. Controlling the marketplace

The fake seller issue is independent of the honeypot issue. There was nothing stopping anyone from creating fake sellers on the original Silk Road. I assume the main reason it didn't happen is that doing so would only help catch buyers

The Silk Road seizure demonstrated that the only reasonable way to participate in any online drug market is to assume the market itself is compromised and untrustworthy. That means you never upload identifying information in cleartext (e.

The Google searches give a hint at DPR's identity. They don't give you the location of the actual Silk Road server. Obviously there's lots of ways that guessing DPR's identity might allow someone with the FBI's reso

Where in the complaint do you see evidence of a website vulnerability? The part you quoted just reads to me as describing DPR's use of a VPN, with the "forensic analysis" part referring to analysis of the disk image after the

Silk Road is (was) a hidden service, internal to the Tor network, so controlling exit nodes wouldn't be relevant here. You'd need to actually be able to analyze traffic within the Tor network. Which still seems plausible, but mayb
