The Linux screen command

Available for most *nix platforms, screen is an invaluable resource for anyone managing multiple SSH sessions. In this segment Darren illustrates the screen command with a story of bits and bricks.

Motion Detecting Webcam Software
Shannon demos her favorite webcam software for Windows, yawcam.

Yawcam is written my Magnus Lundvall and means, quite literally, Yet Another WebCAM software. It’s free, but you can make a donation if you so choose to. Availability is for Windows only. Yawcam stands out to me because of the built in extras.

Features:

  • Video streaming
  • Image snapshots
  • Built-in webserver
  • Motion detection
  • Ftp-upload
  • Text and image overlays
  • Password protection
  • Online announcements for communities
  • Scheduler for online time
  • Multi languages

    Download the software at yawcam.com. In the main window you can enable or disable things that are visible to others. ‘File’ saves image files on local computer. ‘Ftp’ uploads to an ftp server. ‘Http’ can start a stream of webcam images. ‘Stream’ starts to stream video images, and ‘motion’ runs motion detection.

    Under File menu, you can find all the same stuff. Images to Movie can convert images into a movie, so you can choose this to upload images into a video file that you can play in quicktime. Under View menu, you can view different tabs, etc. Stealth mode hides the windows and tray icons. In the settings menu choose your webcam or detect it. Go to settings to change language, camera, connections, etc. Connection detects your public ip and lets you know if you are set up to connect online. File Output takes a photo and saves to a local computer at given intervals. Ftp output uploads images to an ftp server at certain intervals. Http output lets you view images on a dedicated webpage. Stream lets you stream video online. Page Designer lets you edit what the page looks like. You can also edit the HTML template files if you want more functionality. In motion detection you can save images to a path, or an ftp server, and under email settings you can email an image to a selected email.

    Interface Design with the QT SDK
    Jason joins us to demonstrate interface design using Nokia’s QT SDK.

      just wanted to say thanks for the “screen” review. i had used it back in 2001 or so and had forgotten about it. Turns out i needed it again but forgot what it was called. :)

      Hello Shannon,

      maybe zoneminder (http://www.zoneminder.com) is similar to yawcam.
      It also runs on several linux distributions.
      Thanks for the new episode.

      regards

      Michael

      Thanks for the story, Darren. Feel better soon

      You can name screen sessions by specifying -S
      Example
      screen -S irc

      This is better than having to list the sessions to find the right one. On top of that, it beats playing “guess the right pid” with multiple sessions running

      Cheers!

      The show hasn’t been the same since the HakHouse fell apart. Shits WEAK, wizzeak. Bring it back to the name sake Hak-ing, where are the days of rooting phones, multipass usbs, and wireless pwning?
