Ah, good point! Though I think I'll do a dlopen on each file to mimic whatever the loader usually does. I'll do it as a weekend-project :)

mincore is a system call and does not take a pid parameter. This means it has to be executed by each process individually, which would require injecting code into each running process and executing it in some way. Unless there's a tool

I agree, sharing will (most probably) still work on segment-level [0]. But this means that if I have two different executables each linking an identical version of, say QT, in its .text segment, those copies will not be shared. [0] In f

This is an oft-repeated mantra, but is it really true? I don't have a linux desktop running here, but try an experiment: start up a desktop environment such as KDE, and write "free -m" and see how much is there under "sh

I agree. I stopped taking him seriously when he wrote that Java didn't have pointers. (Java's references are pointers w/o arithmetic. But they're still pointers: they're occupying space and are allocated separately

It's possible (and practical!) if you allocate nodes in a List<T> and use indices instead of pointers. Then you can use bit 0 to encode the colour. Using bit 0 instead of sign bit gives the advantage of branch-free code to retrie

A remote attacker is only able to measure total predetermined latency T = t_work + t_sleep. (Actually, he will measure T + t_noise [network, etc.]). By what means can he determine which percentage of T+t_noise was spent in actual work?

> That's silly. Why should every other language adhere exactly to C++'s definition of a reference? It would be silly if NullPointerException were named something else.

I don't think that node is a POD type because it holds two reference members. More on this here: http://stackoverflow.com/questions/4178175/what-are-aggregat... In particular, node does not have a trivial cop

Of course it is. It says so in the language spec, and even in the official tutorial here: http://docs.oracle.com/javase/tutorial/java/javaOO/arguments... Swap is a nice litmus test. To people who claim t

Look up private information retrieval (PIR) and oblivious RAM (ORAM). EDIT: This particular bit from the announcement "but we're pushing query logic and decryption keys client-side" seems to point to ORAM. I was recently read

I think the problem overloads the term knowledge. First, there's knowledge about the external world, the kind which enables you to predict the conseqeuences of your actions and to manipulate the world to achieve desired results. Concre

In section 4 they found that traversing an organized list is FASTER than traversing an array of the same size when both fit into the L1 cache. I find this highly implausible [0] because 1) traversing a list needs more instructions, 2) both

Sorry, I don't buy this. PKCS#11 is a standard, wide-spread, user-space API for accessing cryptographic tokens, just like POSIX is a standard API to access operating system services. I guess it's about the time to write a "dr
