            You add each line to the variable list_Siswa. So for instance the first element of list_Siswa will be ["Nama"," John"], and so data_Siswa[0] equals "Nama" and data_Siswa[1] equals " John". Then data_Siswa[2] throws an error, because there is no such element in the array.

            The code isn't smart enough to see Nama: John and assume the following lines are grades that should be associated with John. If you want that, you'll have to do it yourself.

            How to use select() to set a timer for sockets?
            Asked 2021-Jun-15 at 21:17

            I'm currently using Winsock2 to be able to test a connection to multiple local telnet servers, but if the server connection fails, the default Winsock client takes forever to timeout.

            I've seen from other posts that select() can set a timeout for the connection part, and that setsockopt() with timeval can timeout the receiving portion of the code, but I have no idea how to implement either. Pieces of code that I've copy/pasted from other answers always seem to fail for me.

            How would I use both of these functions in the default client code? Or, if it isn't possible to use those functions in the default client code, can someone give me some pointers on how to use those functions correctly?

            select() can set a timeout for the connection part.

            Yes, but only if you put the socket into non-blocking mode before calling connect(), so that connect() exits immediately and then the code can use select() to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.

            setsockopt() with timeval can timeout the receiving portion of the code

            Yes, though select() can also be used to timeout a read operation, as well. Simply call select() first, and then call recv() only if select() reports that the socket is readable (has pending data to read).

            Rust futures / async - await strange behavior

            I am new to rust and I was reading up on using futures and async / await in rust, and built a simple tcp server using it. I then decided to write a quick benchmark, by sending requests to the server at a constant rate, but I am having some strange issues.

            You are not measuring the elapsed time correctly:

            1. total_send_time measures the duration of the spawn() call, but as the actual task is executed asynchronously, start_in.elapsed() does not give you any information about how much time the task actually takes.

            2. The ran in time, as measured by start.elapsed() is also not useful at all. As you are using blocking sleep operation, you are just measuring how much time your app has spent in the std::thread::sleep()

            3. Last but not least, your time_to_sleep calculation is completely incorrect, because of the issue mentioned in point 1.

            Answered 2021-Jun-14 at 19:44

            No, this will not work, you're using GetBufferPointer which is a naked pointer to memory owned by FlatBufferBuilder, which will be deallocated upon leaving the function.

            Like the docs you quote say, you must use ReleaseBufferPointer instead. Or make a copy, though that is obviously less efficient.

            Better yet to structure your code such that the caller owns FlatBufferBuilder and its passed as an argument.

            Those are stray bytes like *, %, etc. prefixed with some of the lines.

            The stray bytes appear to be a custom stream multiplexing protocol, allowing STDOUT and STDERR to be sent down the same connection.

            Using stdcopy.StdCopy() interprets these custom headers and those stray characters are avoided by removing the protocol header for each piece of data.

            How to create in C or C++ the contents value of Sig type object for digital signature in PDF?

            We are programmatically creating PDF using our in house lib (C++) by adding all the required objects so that PDF readers can render them properly. Currently we are enhancing the lib to support digital signatures in PDF. Our users will use USB token or Windows certificates to sign the PDF. On studying raw PDF file with digital signature, we were able to make sense of all the objects except for the contents of Sig type object.

            ANSWER

            Answered 2021-Jun-10 at 16:48

            Ok, the signature container is embedded correctly.

            But there are issues with the signature container itself:

            • Both in the SignedData.digestAlgorithms collection and in the SignerInfo.digestAlgorithm value you have used the OID of SHA1withRSA, but that is a full signature algorithm, not the mere digest algorithm SHA1 expected there.

            • Then the SHA1 hash of the signed bytes is BB78A402F7A537A34D6892B83881266501A691A8 but the hash you signed is 90E28B8A0D8E48691DAFE2BA10A4761FFFDCCD3D. This might be because you hash buffer2 and

              buffer2 has empty contents data (/Contents <>)

              The hex string delimiters '<' and '>' also belong to the contents value and, therefore, must also be removed in buffer2.

            Furthermore, your signature is very weak:

            • It uses SHA1 as hash algorithm. SHA1 meanwhile has been recognized as too weak a hash algorithm for document signatures.
            • It doesn't use signed attributes, neither the ESS signing certificate nor the algorithm identifier protection attribute. Many validation policies require such special attributes.
