how to make raspberry pi supercomputer

Recently in the toss Raspberry Pi, at that time also did not pay attention to, look at the price, bought Mercury network MW150US Ultra-small 150M wireless USB card. But the tragedy was to use iwconfig and not recognize the wireless card But with lsusb words can see MW150US with is Rtl8188eu chip, search on the network, finally found a solution 1. first download the latest Linux kernel for compiling and inst

The hand has a CCD Camera (Barcode reader/scanner Module), it is through RS232 communication, with the RS232 to the USB adapter to connect the Raspberry Pi, you can complete the hardware connection. For serial communication, it can be realized by pyserial.First, install Pyserial:Download the latest version of the installation package from Https://pypi.python.org/pypi/pyserial and complete the installation w

activated the next time you start Raspberry Pi. There are also. Bash_aliasesFile Reference. By default, this file does not exist: if [ -f ~/.bash_aliases ]; then . ~/.bash_aliasesfi The IF condition is used to check whether the file exists between the imported files. You can create this. Bash_aliasesFile, and add more aliases in it, for example: alias gs='git status' You can also directly add other th

This is a creation in Article, where the information may have evolved or changed. Today I turned over the old data and found something. When the company's servers were not in place (startups had no way). Talking about the server, a colleague took out his raspberry Pi. I think, I can do it. Go would have supported multiple platforms. Redis is written in C and should not be a problem. Finally, although the m

1. Preface: You need to understand the concept of Bitcoin You need to know the computing power of the Raspberry Pi, which is much less effective than the graphics card mining, the baked cat, the USB mining, etc. If you want to toss it, come on. 2. Prepare: You want to dig Bitcoins, first of all to know where to dig Bitcoin, Bitcoin is in a mine, so we register the mine pool account It could be that the BT
