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() {
Serial.begin(9600);
...
}
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.


mpirun -np $numcores $dir/va

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


ClassFormatError when invoking defineClass with bytes read using JarInputStream read method
by surfsatwerk in Programming Languages

I am using the following method to read bytes from jar entries (containing class files only). There is no jar file inside the jar.


private List<byte[]> readFromJarFile(File cp)
{
List<byte[]> cbytes = new ArrayList<byte[]>();
try
{
java.util.jar.JarInputStream jin = new java.util.jar.JarInputStream(new java.io.FileI

Is Socket.getInputStream().read(byte[]) guaranteed to not block after at least some data is read?
by sep in Programming Languages

The JavaDoc for the class InputStream says the following:


Reads up to len bytes of data from the input stream into an array of
bytes. An attempt is made to read as many as len bytes, but a smaller
number may be read. The number of bytes actually read is returned as
an integer. This method blocks until input data is available, end of
file is detected, or


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

passing a parameter with onclick function is read as a variable when it should be read as a string
by wraith in Web Design

Here is my issue:


I am creating dynamically a button with an onclick function like this:


$("#test).html('<input type="button" value="Close" onclick="remove('+param1+','+param2+');" />');

The parameters are well read but the function is not trigger, and I've got this error message:
"bob is not defined" when bob is the string value of t


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


RandomAccessFile.read() returns value greater than number of characters read into string
by chuck1723 in Programming Languages

I have a RandomAccessFile raFile from which I'm reading data into a buffer in fixed sized chunks:


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