Here is a fun story about screenshots.<p>All of us had that feeling: you are browsing the Internet and suddenly see something cool. You either forget to bookmark it or that cool thing is not cool enough to be amongst your bookmark items (which are clearly much cooler). Sometimes you may also think: "Whatever, I have my browser's history, I'll find it later if needed". Later, you want to show that cool website or app or whatever to your friend. You check your bookmarks, well, nothing there. You check your browser's history and can't find it - you don't even remember the website. Later, you realize that on top of evertyhing, you were using the Incognito mode and there is no way to find anything for that session.<p>Well, when it comes to browsing history, there is a chance to look back and go through the visited websites (if you are lucky). However, what about web forms or something you were coding and then said "f### it, i don't need it", closed the file and then in a few days later: "damn, i should've saved that file"..<p>So, I had millions of situations like that. At some point, I was like: "this shit can't go like that forever". And I found the solution.<p>I installed a spyware on my own computer. The spyware would make screenshots either every Nth second or each time a user switches from one application to another. To activate the spyware's interface, you (as an evil hacker who has access to your victim's local computer) would have to setup a secret key combination (say Ctrl+A+I+P), followed by a password. The spyware interface allows you to see everything that was happening on the computer: list of loaded applications, screenshots (!), keys you typed, everything!<p>This post gets so long, but the result was a pure success. I used the tool a shit ton of times to recall what I did in the pass.<p>FAQ:<p>Q: Wouldn't the screenshots take a lot of space on your hard drive?<p>A: No. They were compressed. The quality was good enough to understand everything.<p>--<p>Q: What about the data going to someone else's computer over the network, say, the creators of the spyware?<p>A: This was a local spyware. No network traffic whatsoever.<p>--<p>Q: Do you still use the tool?<p>A: No. This was many, many years ago. I was a Windows user back then. I haven't seen similar tool since I switched to Mac computers.
