We interrupt your regularly scheduled tooting to bring you a message related to my employer, which I am not speaking on behalf of: My team is hiring a security engineer in London. It is in person. Please DM if you'd like to talk about the role and perhaps be referred. (please look me up on LinkedIn if you want to know where I work, but it's a megacorp you're familiar with)

Previously, I built something that detected LibreJS, bypassed its "trivial JavaScript only" gate for code without a free license, and played the free software song.

I'm considering getting an LTO-8 setup for backup. My home fileserver has about 40-50TB in it, and even with a "never restore" assumption the break even time vs "store everything in glacier deep archive" is pretty reasonable. Anyone gone this route and have opinions? #linux #homelab

@tqbf@infosec.exchange I'm not sure if you read your mentions here, but if you listed 2010 as a copyright year on your website as a way to troll people with extreme pattern matching brain you did a fantastic job

On the one hand, props to Kovid Goyal for fixing this quickly, on the other hand I'm a bit salty that he considers it not a security issue to be able to probe for file/directory existence and get back file sizes. I included a PoC that lists the loaded kernel modules in my report. https://github.com/kovidgoyal/kitty/commit/87ab3e98f4d399337777e4329960d7cd09101e99

STOP DOING SWAP PARTITIONS HARD DRIVES WERE NOT SUPPOSED TO ACT LIKE RAM YEARS OF LINUX SYSADMINNING yet NO REAL-WORLD USE FOUND for going beyond CLOSING A FEW TABS Wanted to avoid the OOM killer anyway for a laugh? We had a tool for that: It was called ZRAM "Yes please give me a dedicated 64GB logical volume of SWAP. Please give me unresizable block devices trapped at the end of my disk." - STATEMENTS DREAMED UP BY THE UTTERLY DERANGED LOOK at what Neckbeards have been demanding...

Radxa says ROCK 5 ITX board I returned can't be repaired, and will be scrapped. They're refunding me, but I was counting on having two of them. Anyone have a ROCK 5 ITX or ROCK 5 ITX+ they'd be willing to sell me for non-scalper prices? Would also be happy to buy an Orion O6. #embedded #embeddedsystems #linux #homelab

So, I have run the numbers, and a PoE toaster running Linux is actually very feasible, and could be built for about £350. It would need batteries, but at that price point it could have enough to make eight slices of toast. cc @kajer@infosec.exchange
