Not system-wide though, and possibly incompletely and with bugs. The entire socket API is far from being simple to wrap like this, especially when you consider that it includes all the various IO functions (read/write, send/recv,

I've just said how it's a bug, read my comment again. The commit message says it should only decide not to swap when there's enough RAM. The evidence in the article says otherwise. I'm not saying it's not a valid fe

"Looking at the patch, it looks like swapiness=1 now does what the old 0 did." Yeah, it seems, but the commit message, in my incomplete understanding, contradicts what you're saying. Also, I wouldn't feel so confident ma

What is the page doing with that code display? As soon as you click into it or select text inside (just like that, because you tend to do that while reading), it unexpectedly changes into some kind of plain text view and it seems you need t

This looks like a bug. The kernel shouldn't raise OOM if there's swap available, the swappiness=0 should just make it not swap unless absolutely necessary. From my interpretation of the commit, it's supposed to improve the im

About the "Lightweight Proxy" (ssh -D), if you want it to be transparent to the application (not require SOCKS support), you can use my tun2socks[1] program. This is useful if you can't or don't want to set up an SSH tun

Actually, many password forget forms do not provide any information about whether the email was recognized or not. More than once I've seen a message along the lines if "If the email entered was associated with an account, a passw

"This illustrates a difficulty naive backwards-error analysis" It's not naive. It's conservative, the exact opposite.

Anyway, my example was a bit too theoretical. A better version is one where L and M are integers which are not necessarily representable. Here: http://ideone.com/1Xkhjp

I suspect a bug in your proof right at the beginning, where you say "exact result be of the form N + epsilon, with 0 < epsilon <= ulp(N)/2, and N an exact integer". Assuming you're referring to the result of the en

Though, as nice as the examples are, FP rounding problems in practice are rarely due to binary/decimal conversions, which are only relevant when reading and writing decimal encoded numbers. These are normally absent when doing tasks su

by ambrop7 13y ago
A common and simple way to treat FP mathematically is by bounding the result with the machine epsion u [1]. For example, given FP numbers x and y: x <fp_mul> y = (1+e)xy ; abs(e) <= u The u ideally depends only on the FP format an

It's kind of implied by the parameters that they point to the same object; they're named "pos" and "end" after all. But I agree, a count variable is nicer. The subtraction also has a (very theoretical) problem

All your variables are not 64-bit aligned. An array of 16-bit integers will generally use 16 bits (2 bytes) per integer. So will two or more subsequent integers in a struct. In general, variables smaller than the alignment of the CPU (but s

If you're writing that code, you SHOULD know every possible incorrect certificate format. If you don't, you should learn from the relevant standards and other materials, or admit that you're not capable of writing that kind o

This is bullshit. You can write tests for TLS libraries just fine. And yes, I'm saying that without ever doing any programming of TLS libraries (just using them). For certificate verification, you craft various correct and incorrect ce
