I keep trying to create a hot spot using Ubuntu's default tools. I am not internet sharing, I just want to connect to the devices. When I try to create a hot spot, it disconnects from my network, waits, and then reconnects, never seeming to create a hot spot. How can I create a hot spot. (I am not sure what info I would have to give you, so just ask in the comments and I will add it.)
Hi, I have a large file with number of records in there. I need some help to find only first row based on a key and ignore other rows with the same key. I tried few things but file is huge(30 million rows).
