For example, pairing on a real world problem or a paid/unpaid take home exercise. The companies and teams listed here use interview techniques and questions that resemble day-to-day work. Using sites like HackerRank/LeetCode probably fall into a similar category. ![]() Whiteboards are not bad – CS trivia questions are. "Whiteboards" is used as a metaphor, and is a symbol for the kinds of CS trivia questions that are associated with bad interview practices. (OPTIONAL) In your pull request message, add additional context on the interview process if necessaryĪ list of companies (or teams) that don't do "whiteboard" interviews. I have followed the ( ) prescribed in the contributing guidelines (Don't worry about the difference I have to look it up in the manual every single time I need it.Merge #1352 1352: Update Url for rapidapi r=poteto a=londonjob The -L says that programs will attempt to connect Locally, and the -R says that programs will attempt to connect Remotely. It took me years to get the hang of the difference between -L and -R connection forwarding. Programs on your server (or elsewhere on the server's network) must be able to connect to server:6000 (or server's routable address, port 6000) to initiate the connection. With this command, a program on the laptop must be listening to port 7000 for connections. If you wanted it to be open to all machines that can contact the server, then you could use ssh -R *:6000:localhost:7000. By default this is only open to connections initiated on the server machine. If you want connections made to server:6000 to be forwarded to laptop:7000, then you could use ssh -R 6000:localhost:7000. Programs on your laptop (or elsewhere on your local network) must be able to connect to your localhost:7000 (or your machine's non-routable address, port 7000) to initiate the connection. With this command, a program on the server must be listening to port 6000 for connections. This restricts the port on your laptop to connections initiated on the laptop itself. ![]() If the connections originate on your laptop then you could slightly amend this to: ssh -L localhost:7000:server:6000. If you want connections made to laptop:7000 to be forwarded to server:6000, then you could use ssh -L 7000:server:6000. Since I don't know putty, I'll give the corresponding commands from OpenSSH hopefully it'll be easy to find the corresponding options in the GUI config boxes of putty. The connection will always be initiated from your laptop (because it cannot be directly addressed from the other machine) but you will use one or the other connection forwarding arguments based on how you want the port forwarding to work. The direction of your arrows has no relationship to which machine has publicly routable IP addresses - you need to know which direction you want your arrow to go based on the problem you're trying to solve. ![]()
