  • I have had an identical problem a few years back, with a Samsung 2 in 1 that worked perfectly on AC, but had exact issues on battery.

    It was the “power saving” capability of the GPU that triggered it on battery. So simply disabling this is the integrated Intel GPU control panel (in Windows) fixed the problem. Laptop is still running now and works with my sister in law.




  • I’m a fan of SystemRescue. It’s specifically designed for backing up and fixing disk layouts, and it supports both BIOS and UEFI booting.

    I’ve never tried it on Secure Boot enabled devices (I usually disable secureboot before troubleshooting systems), so I do not know if they use a valid signed efi-stub.

    For “simple” stuff, I usually boot a live ubuntu image. If the machine has sufficient RAM, I can get away with installing quite a few packages that I need for troubleshooting (gparted, gdisk, etc.).




  • I second that. Amazing easy to use, configure, supports (LetsEncrypt) certificates via DNS-01 challenge and integrates with ease with most DNS providers.

    Paired with authentication providers (keycloak, authelia, authentik), the “advanced” textbox lets you do forward proxying really easy, or customize your “basic proxy”.

    I’m not sure how many of these features are present in Traefik, it would be really nice if any of you know if any of these are easily supported in it:

    • Forward proxying
    • Custom rewrites (nginx internal; rewrites)
    • Unattended DNS-01 support with ACME (LetsEncrypt)

  • Very capable tool, and useful in some cases. Does require security of the ptrace call to be unset (ptrace_scope) or set to the default (insecure one).

    I’m a big fan of using ptrace_scope to restrict PTRACE_ATTACH to only allow parents (or grandparents, etc.) to attach to children. Quite useful - this particular security feature was unique to grsecurity and was good enough to be implemented in mainline (changed).

    If you care about whether user processes should not be able to attach to other processes under the same UID, don’t use it though!



  • As Netflix tested these changes in other parts of the world first, they had sufficient metrics to know how this change will affect their user-base. They are expecting an increase in subs and in income.

    I cancelled my sub (4 screens), which was shared among 5 people. Two of these decided to resubscribe by themselves, although not in the 4 screens configuration. From my calculations this means:

    • Cancellation of a 18EUR subscription
    • 2 new customers on Standard, 13EUR each
    • Netflix took a profit of 6EUR from this operation, while gaining an extra subscription.

    I think this matches their “100% increase in subs” metric. The only question is how many others who resubscribe will go for the 2 screens (Standard) sub, or the 1 screen (Basic) sub. With basic, the same situation would result in a ~2EUR decrease in revenue.
