I actually take Modafinil for narcolepsy. It's not quite as life-changing as the recent articles make it out to be; it doesn't make you smarter or think faster or anything of the sort. It just removes the fog in your brain that builds up when you have too many things competing for attention.
One major downside, however, is it's fairly quick to build up an immunity to, especially if you have it as a medical prescription.
Overall, it's pretty useful, and as far as I know, harmless. Just don't expect it to be like the movie Limitless.
Clipt is a small and lightweight solution to using your clipboard across multiple computers or VMs. By connecting to a central website or privately hosted server, Clipt allows clients listening on specified IDs to receive text and push it directly into your Operating System's clipboard.
