Problem: Java-Read socket (Bluetooth) input stream until a string (<!MSG>) is read
by dummyadresse in Java

I use the following code (from Bluetooth Chat sample app) to read the incoming data and construct a string out of the bytes read. I want to read until this string has arrived <!MSG>. How to insert this condition with read() function?

The whole string looks like this <MSG><N>xxx<!N><V>yyy<!V><!MSG>. But the read() fu

Arduino EthernetServer read() only works when Serial is initialized and read characters are printed
by Rakewell in Programming Languages

I have an Arduino project where I read data from a webserver.

I have an EthernetClient that reads the data character by character in a callback function.

My working code looks like (only the relevant parts):

void setup() {
void loop() {
char* processedData = processData(callback); // th

read: read error: 0: Resource temporarily unavailable after mpirun in bash script
by Guid in Development Tools & Services

I have tried to find the solution online for my issue. I have narrowed it down to mpirun causing the issues as merely invoking the executable does not return issues. I have tried to redirect outputs but to no luck.

I receive the error in the title for every read I attempt to do after I run mpirun. Here are the relevant line of code.

Performance: use a BinaryReader on a MemoryStream to read a byte array, or read directly?
by piratus in Programming Languages

I would like to know whether using a BinaryReader on a MemoryStream created from a byte array (byte[]) would reduce performance significantly.

There is binary data I want to read, and I get that data as an array of bytes. I am currently deciding between two approaches to read the data, and have to implement many reading methods accordingly. Aft

byte[] fileBuffer = new byte[BUFFER_SIZE];
while((readBytes = raFile.read(fileBuffer) >= 0) {
String bufferStr = new String(fileBuffer, 0, readBytes);
String testerStr = new String(fileBuffer);

Idea on implementing read not read functionality for social network's notification?
by hunaid mushtaq in Network & Servers

As for Stackoverflow itself, the owner of a question and all others who give out comments and solutions are involved in that specific question. Then when there is a new answer or new comment, people that are involved will be notified until they actually read it. Personally I think, when building up the database table, we need a table to link members to questions to show the involvement, but I'm
