I've been fiddling with getting this to work for a while now, so I suspect some sort of fundamental misunderstanding about how pipes work is the root cause of my troubles.
My goal is to initiate a TCP connection to some remote host via netcat and have two named pipes on the filesystem: one that processes can read from to get incoming data, and other that processes can write to that serve as outgo
I've been tracking the Top500 Supercomputer List with a particular eye on Linux for some time now, highlighting how Linux continues to power the majority of the world's fastest supercomputing systems. So it's no surprise to see continued dominance for Linux, but there are some interesting changes every six months when the new fastest supercomputer system list comes out.
I'm writing a simple chat client in C++ on linux to connect to a win32 chat server on my computer also written in C++. I'm confident that the server works but the chat client is giving me some trouble. I'm forking the chat client and have one process dealing with incoming messages and another dealing with sending messages.
I'm duplicating a "master" pipe with tee() to write to multiple sockets using splice(). Naturally these pipes will get emptied at different rates depending on how much I can splice() to the destination sockets. So when I next go to add data to the "master" pipe and then tee() it again, I may have a situation where I can write 64KB to the pipe but only tee 4KB to one of the "slave" pipes.
Written by: Stephen WithersSony claims it's new XQD S series memory cards are the "fastest ever."
Based on internal testing, Sony says its forthcoming XQD S series memory cards work at up to 168Mbps, making them the fastest on the market.
How fast is that? Fast enough to handle up to 108 frames in RAW format shot in continuous mode at 10 fps.
I have sql server express 2012 installed on windows 2008, locally everything works just fine i can connect via tcpip and named pipes. Remotely i can connect with ssms only using named pipes.
I have tried disabling the firewall on both sides to eliminate blocking traffic.
I've got some code I'm writing that is expecting messages from a Matlab program via a named pipe, e.g., "/tmp/named_pipe_0". I can get pipes mkfifo and opened find, but when the C program goes to read() from the pipe, instead of the expected 5004 bytes, I'll get short values like 4096, 904, 5000, 4096, etc.
Disclaimer: this is for an assignment. I am not asking for explicit code. I am only asking for help understanding the concepts so that I may learn the material without copying what someone else has done.
My assignment is to take some data from a text file, parse out the words, sort them alphabetically, delete the duplicates, and output them to a new text file.
