-j4 says use up to 4 processes in parallel. Make has a jobserver that does parallelism safely with respect to the dependency graph. So for example, even if we have workers to spare, it won't try to build all.min.js until all of the .ug

Fully agree with you on the clunkiness of Google Groups. Thing is, most other mailing list web interfaces are even worse; not only are they lacking a threaded discussion view like we enjoy here on HN, they often only show one message at a t

The iteration count used by TrueCrypt [in its PBKDF2 key derivation] is either 1000 or 2000, depending on the hash function and use case. In both cases, this iteration count is too small to prevent password guessing attacks for even modera

Absolutely beautiful visualization. A couple cautions about drawing conclusions from this data though: 1. A trend in the outliers of a distribution does not imply the same trend in the mean values of the distribution. Although I'm sure

That's essentially how the GPG feature works. Cool. I think that's the way to go. If you needed GPG for things beyond the initial checkout, automated git deploys (among other things) would be out of the question. You might be c

GPG support will be the upcoming release (see my other comment). Saw that -- awesome. I rolled something similar where gitcrypt.salt and gitcrypt.pass were stored in a gpg-encrypted file. After cloning, you decrypt once with gpg, then un-

I use gitcrypt to keep sensitive configuration data out of git history, while still being able to diff, log, merge etc those files. It works well for that. Note, gitcrypt uses symmetric encryption and stores the shared key in your gitconfig

If the 1% don't churn into the 0.01% when it loses 75% of its members, then where do the replacements come from? I agree though, longitudinal studies are the most interesting.

by sigil 13y ago
The evidence we have so far points to a higher churn rate the closer to the top you are. According to this [1], the top 1% had a churn rate of > 50% over a decade, while the top .01% had a churn rate of > 75% over the same period. The

Question for fellow paranoid HNers: what do you use to decommission a server? Do you run shred(1) on all "interesting" files? Do you write over the block device itself with random data?
343.
by sigil 13y ago
But you can doublespend whatever coins you've got, and reject all other transactions, so the effect is the same. (You're right though, I phrased that incorrectly with "vote.")

You should check out djb's redo [1], specifically the implementation by apenwarr [2]. It's close to the separation of concerns you're looking for: programs written in your language of choice enumerate the dependency graph, an

Well not zero, just below half the mining costs, right? As long as it's below that, you still lose more taking over the new cryptocurrency than you gain. And that's also not taking the price drop post-takeover into account, which
346.
by sigil 13y ago
Shouldn't the takeover risk be priced into a new cryptocurrency? If coin price > mining cost / 2, it becomes worth it to acquire 51% of mining capability so you can vote the other 49% to yourself, no? But then again, once you h

It's nice to be able to use the unix toolset (grep, cut, sort, join, etc) on all kinds of data, not just strictly "textual" data. They're often my tool of last and only resort when dealing with very large datasets. Sure,

Meh. What if some data has ASCII 28-31 in it? If you're not using a "real" escaping mechanism, and instead relying on the assumption that certain characters don't appear in your data, then I don't see anything wrong

I was mostly responding to the claim that Bitcoin transactions aren't reversible. To your point: I suspect multisig doesn't help solve the problems we keep seeing with exchanges. An exchange converts between currencies, and wants

Sure, arbitration requires a trusted third party. Look though, the situation is a huge improvement over what we currently have: 1. Arbitration services can be decoupled from payment services. With multisig, buyer and seller get to choose

Good to know that you can log into HN with an unpatched w3m now. w3m sends "Content-length: " instead of "Content-Length: ", which HN used to dislike. https://github.com/acg/w3m/commit/5946
