DaVinci Resolve Studio Crashes Adding Text+? Here’s the Fix!

Sheridan Computers @sheridan.co.uk · 4d

Do you think Microsoft will eventually charge a subscription for Windows?

With Windows 11 becoming increasingly locked down, the company’s clear shift towards recurring revenue through Microsoft 365, Copilot, and other cloud-based services, it’s fair to ask.

Tribute or sin: rewriting #tinydns in #Rust

My biggest achievement and my biggest failure, all in one.

Not a choice, lack of options. Distros dropped it, even though it spent 20 years on the internet without a single security issue - who else can claim that?

#tinydns #djbdns #rust #freebsd #linux

My own #DNS validation tool just humbled me - anyone can make mistakes! 🚨

My validation tool found 8 critical errors hiding for 10 years. 💩

It started as #tinydns / #djbdns to #BIND converter, evolved to a bidirectional conversion & validation tool.

Launching #TinyMan as #OpenSource soon...

The best part of producing helpful content is knowing you did something that helped someone!l somewhere - even if it's just one person.

Tech tutorial channels can be hard, no point in shitty click bait titles.

Hot take: Lots of “Windows 11 nukes SSDs” posts. We manage 1,000+ devices and 0 incidents.

Could be a niche edge case; could be hype. We’re still patching, keeping backups, and watching for credible vendor/Microsoft guidance. What’s your real-world telemetry saying?

Go full #MrRobot with the pocket-sized mini pc from #MeLE.

Works great with @tailscale.com, @netbird.bsky.social or @zerotier.bsky.social for remote access.

Controlling #Windows from #Linux - boom! 💥

Finally managed to get this #ScreenConnect alternative to compile on Windows with full Nvidia hardware encoding via #ffmpeg.

Maybe we will get an open source tool! This is capturing 4K, fullscreen #YouTube video complete with #NerdStats

Mac next? 😁

If I can pull off an #OpenSource #RMM, and an open source remote access tool, this will change the way vendors (ex car-sales) farm #MSPs.

The remote access thing forced my hand. But, the RMM can launch it on demand, and terminate it when done - no 24/7 always on.

Nothing commercial or free does it
