  • I remember before scrambling they just put blocks that prevented you from going to certain channels. I somehow figured out if you ran the cable box through the VCR first and put it on channel 2 while the TV was still on 3, it would shift all the channels down one. Cinemax was channel 14, which our box just would not go to. But it would go to 13, so doing my little trick teenage me got to watch a lot of skinamax.


  • If I understand correctly, the signatures generated by PuTTY aren’t perfectly random, so if someone got a hold of a bunch of keys from a server, they could figure out the pattern. It takes about 60 keys. This affects not just PuTTY, but also FileZilla, WinSCP, TortoiseGit, and TortoiseSVN.

    In other words if you have NIST P-521 keys, or any others using 521-bit ECDSA, you should revoke them and generate new key pairs. After you update your software.


  • I installed some security cameras around my house and set up Shinobi using an old PC. Unfortunately the PC is too old to use the built-in detectors in Shinobi. So, I took my first dive into playing around with some image detectors.

    I wrote some python to download the daily recording from old PC to a newer one with a 3080 GPU. Then checks the videos for people. It will then trim the videos to only include times were there are people in frame. It cut my the storage requirements by over 95%.








  • That’s pretty similar with what happened with me and the train. Kept getting random drops from a plant. I went out to investigate and everything tested perfect and the network was staying up. That was until a freight train rolled by. Turns out AT&T had run the line by shoving a piece of PVC through the gravel between two cross-ties, then running the cable through it.
