You don't need a government's resources. You need a programmable firewire device, like an embedded Linux device. You also need ten seconds of physical access to their FireWire port. That's a lot easier than hacking a battery and convincing

SIM cards need to be registered so that the Indian police can track criminals. Personally I disagree with this. Criminals will disregard this law so it will usually only apply to law abiding citizens. Try explaining that to the Indian CBI t

I don't think so. Certainly not for any peripheral that is allowed to do DMA. Though plugging in a malicious firewire peripheral is a lot more practical than replacing the battery... http://www.hermann-uwe.de/blog/physical-memory-attacks-v

IANAL, but legally speaking unauthorized access is a crime regardless of how easy it was to gain access.

I've had good experience with 2GB heap dumps. Actually dumping it was, in my experience, pretty quick. It was essentially as fast as the machine could do that much sequential IO. You get a lot more detail, like what was in those Strings tha

To clarify they said "availability zones", not "regions", which is a huge difference in terms of latency. And yes, you can tell RDS which availability zone to use.

A small group of contributors make the most edits by count. A diverse group of contributors write the most prose content, usually on a topic that they're expert in. So the core wikipedians are organizing/wikifying/categorizing and that's th

Purchasing a 50% random sample of all tweets in real time is reported to be $360,000 per year [1]. Apparently you can get the 100% feed for a negotiated price. If they can sell many licenses for those feeds, which I think that they can, the

There are several ways to do it. Kill all the instances. Use a firewall to blackhole all the instances. Use traffic shaping to degrade the latency or packet loss of all the instances.

Well then I was wrong. Apologies.

"Availability zones are permuted randomly for each customer" This statement is false. AZs map directly to physical facilities. If you and I both ask for instances in us-east-1b they will have lower ping times than if one of us has an instan

The drawback with multiple processes is that they each have all the compiled bytecode on their heap. When I "import nltk" my heap goes from ~12 to ~36 MB. Add a few more dependencies and you end up wasting a non-trivial amount of RAM on pyt

That is an awesome GC and I wish I could have it. AFAIK they are having trouble because they mmap/munmap a lot, and virtual memory systems on modern OS don't do that efficiently enough.

It is a tradeoff between ease of use and security. These sorts of features require the developer to check every single query string consumer or you end up with gaping security holes. That will result in security exploits in any moderately l

The question is not "are journals biased?" The question is, are more respected journals less likely to publish a falsehood? If the "better" journals have more accurate reviewers or more reviewers then yeah, they will publish fewer falsehood

The scientific method is based on the principle that peer review winnows out false hypotheses. If n observers each detect a falsehood with probability p then the probability of missing the falsehood is (1-p)^n. More reviewers and more accur

Yeah, it opens with snark. But then the article goes through the arguments and figures in the paper and refutes the hypothesis, so it's not empty snark. Publishing a paper in a fake journal does damage the validity of the claims. Papers wit
