Like in the title, I want to encrypt data, which is sent over network. Because I decided to use TCP and/or SCTP protocols I cannot use SSL/TLS. That's why I want to implement my own solution based on SSL idea. Two peers will exchange symmetric algorithm's key (AES0 using asymmetric algorithm (RSA) first and then continue communicatio...

Sorry for the vague question, but I've just written some php code that executes itself as CLI, and I'm pretty sure it's misbehaving. When I run "top" on the command line it's showing very little resources given to any individual process, but between 40-98% to iowait time (%wa). I usually have about .7% distributed between %us and %sy, wi...

I'm not sure if this is possible, but I'll give it a go. I'm creating a device where I have to add a customized user-interface instead of the normal operating system UI. I'm thinking of installing Windows CE (or .NET MICRO) or Linux, but I'm not sure which OS would let me do this. Also, the software (UI) would load instantly and doesn't...
I have a C file running on Linux. It prints some lines in red (failures) and some in green (passes). As you might expect, it uses escape codes in the printf statements as follows: #define BLACK "\033[22;30m" #define GREEN "\033[22;31m" printf(GREEN "this will show up green" BLACK "\n"); If the BLACK at the end wasn't there, the ter...
Solving this problem would make my life a hundredfold easier, because working in Windows XP blows, and save for this one Adobe POS, I would be working entirely in Linux. The Flex project I'm trying to build can be built successfully on Flexbuilder 3 Pro (licensed version, 3.2 SDK) in both Windows XP and Mac OS X. I followed these instr...
I am trying to debug programs on an ARM target device with GDB and GDB seems to be acting odd with regards to ld-linux.so.3. It's a simple program that just printf("Hello World"). Approximately half the time, gdb it will run and the other half jump to this error after typing run: Program received signal SIGILL, Illegal instruction. 0x2...
I am interested in the "best approach" to making sure your Linux & GTK based application is built from the ground up to support i18n and localization with minimal amount of pain. I've always heard that localization can be a real pain point to implement, so I am wondering if there is a good guideline and/or approach that can help make it...
I saw a bash command sed 's%^.*/%%' Usually the common syntax for sed is sed 's/pattern/str/g', but in this one it used s%^.* for the s part in the 's/pattern/str/g'. My questions: What does s%^.* mean? What's meaning of %% in the second part of sed 's%^.*/%%'? ...
