I'm guessing it's different depending on model, but on my SM-X900 (US model Tab S8 Ultra), the key used to sign the vbmeta image (Android verified boot's root of trust) is different from every key used to sign the system apps

I haven't personally used any tool besides zrepl, but I like the flexibility it offers. It can do both push and pull-based replication. I have my offsite target server (with its own retention policy) pull from the source server. If the

Interesting. In my area, Spectrum would give out the same IPv4 address and IPv6 prefix seemingly indefinitely as long as I kept the MAC address and DHCPv6 client DUID the same. It'd persist across DHCP releases and renewals too. Manage

This article was written by one of the developers of the "Newer" ROM hack series for New Super Mario Bros Wii. It goes into detail about how the C++ symbol mangling map in the Nvidia Shield port of the game is identified by hashes

None of my self-hosted things are internet facing, so I use the DNS-01 challenge type. For internal DNS, I run the powerdns authoritative server. Each ACME client uses RFC2136 (TSIG) to update the _acme-challenge TXT record. I have a pdns l

My main switch is the Aruba S2500-48P (48x 1Gbps POE + 4x 10Gbps SFP+) and I use 2 Unifi UAP-AC-HD's for Wi-Fi (which I no longer recommend due to ongoing firmware issues). For routing, I have a custom built desktop with a micro-ATX bo

This is what I've been doing for the past couple years: 1. Pictures are either manually copied to a staging folder on my storage server (for DSLRs) or automatically synced there via Syncthing (for smartphone cameras). For the latter, S

apktool is such a wonderful tool. As a side note, with newer versions of Android, it's no longer necessary to extract bytecode from odex/vdex files to disassemble systems apps or frameworks too. The apk/jar files all contain

For Linux, I almost never reinstall. Most of the package managers I've used don't make it too difficult to: * verify the checksums of everything installed * find packages that no longer exist in any enabled repo * find packages (n

Is this a regional (or plan-related) thing? I have no problem hitting 200Mbps to my wireguard server at home, though I'm on one of the old Simple Choice plans (with the Binge-On throttling disabled if that matters).

It's a little bit longer, but bash/zsh support `printf '%q ' <args...>`, which produces output where any characters that may be interpreted by the shell will be escaped.

My understanding is that full system backups on Windows requires the tool to create VSS snapshots and back up from the snapshot. Any tool that just copies files on the disk won't work. I use Veeam Agent for this purpose (free, but not

Yep. Same thing with 1800xx911xx (and so on). I made that mistake as a kid with my parents' old unactivated phone. That's when I learned any mobile phone can call emergency services.

Android's PackageManager system doesn't use CAs. It's a trust-on-first-install system where any updates must be signed with the same cert as the original install. I don't know if it's still the case, but when I last

That's matches what I've observed on my ~2017 Dell XPS. On Linux with fwupd (and Windows), it would write the updater to the EFI partition and then set it as the default boot entry for the next boot. I had to manually add Dell&#x2
