Sheridan Computers @sheridan.co.uk · 10/10/2026Fix merged into GNOME's GLib that benefits FreeBSD users! Large file copies could sit at 0 bytes with no progress updates, and cancellation could be unresponsive. Our fix addresses both issues. #FreeBSD #GNOME #OpenSource 031
Sheridan Computers @sheridan.co.uk · 29/09/20267 years ago today I started a YouTube channel to record videos for my own reference, such as stripping down laptops. Today that goal has moved to teaching others what I can about networking, firewalls, storage, and operating system. #YouTube #TechTutorials youtube.com/@sheridans 010

Sheridan Computers @sheridan.co.uk · 19/09/2026We needed a quick way to test laptop keyboards without an operating system installed. Existing tools were buried inside large diagnostic images, so we created Kbdcheck: a free 47 MB bootable USB image based on Arch Linux: keyboard, mouse and touchpad tester. Use FREE, no registration. kbdcheck.com 001
Sheridan Computers @sheridan.co.uk · 18/09/2026Part of refurbishing a laptop properly is checking the things that are easy to miss. Keyboard, touchpad, buttons and other inputs all get tested before it leaves the bench. Just one part of the refurbishment process. #SheridanComputers #RefurbishedLaptops #LaptopRepair #Manchester #Stockport 000
Sheridan Computers @sheridan.co.uk · 07/09/2026We independently verified the behaviour described in the latest ScreenConnect advisory.

Sheridan Computers @sheridan.co.uk · 15/08/2026HDMI or DisplayPort? For a PC monitor, I’d normally use DisplayPort if it’s available. TV or console? HDMI. Basic office screen? Either is fine. And if your new 4K monitor feels oddly sluggish, check the refresh rate an older port or cable may be limiting it to 30Hz. 000
Sheridan Computers @sheridan.co.uk · 05/08/2026This is where the magic happens. 🔧💻 My son is spending part of his six-week holidays in our downstairs workshop, where we handle all laptop and PC repairs in-house. Not a bad place to learn how things really work. 010
Sheridan Computers @sheridan.co.uk · 31/07/2026We’re an MSP, but we’re engineers first.

Sheridan Computers @sheridan.co.uk · 21/10/2025A few years ago, cybersecurity felt like a big-business problem. Not anymore. Most attacks we respond to now start with something small - a remote employee’s unpatched laptop, or an old remote-access tool left open. #SmallBusiness #ITSupport #Manchester 030
Sheridan Computers @sheridan.co.uk · 11/10/2025Do 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. #Microsoft #Windows 000
Sheridan Computers @sheridan.co.uk · 06/10/2025Do we really need a month for cybersecurity awareness? There are 11 other months worth protecting too. Hackers aren't just active in October. #HackersDontTakeHolidays #EveryMonthIsCyberMonth #CyberSecurity #CyberSecurityAwarenessMonth 021

Sheridan Computers @sheridan.co.uk · 06/09/2025Tribute 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 021
Sheridan Computers @sheridan.co.uk · 05/09/2025My 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... 021
Sheridan Computers @sheridan.co.uk · 23/08/2025The 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. Appreciate each and every one of you <3 #YouTube #TechGuides #OpenSource 020
Sheridan Computers @sheridan.co.uk · 19/08/2025Hot 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? #Windows11 #MSP #PatchTuesday 100
Sheridan Computers @sheridan.co.uk · 13/08/2025Controlling #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? 😁 042
Sheridan Computers @sheridan.co.uk · 12/08/2025If 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 021
Sheridan Computers @sheridan.co.uk · 05/08/2025Didn’t See This Coming… 👀 I started uploading to YouTube thinking it might help someone; if not, at least it’d help me remember how I fixed something. #YouTube #Tech #VideoTutorials #Sheridans 023
Sheridan Computers @sheridan.co.uk · 23/07/2025Asked an AI coding assistant what it thought about running a remote desktop relay in a FreeBSD jail using quic, ephemeral ports, magic packets, and dynamic PF firewall rules.

Sheridan Computers @sheridan.co.uk · 11/07/2025Recent reliability and security hiccups around #ScreenConnect got me thinking: could we build something leaner, safer, and open? Last night I spun up a proof-of-concept in #Rust (screenshot below). If I'm developing an #OpenSource #RMM on Rust, seems next logical step. 021
Sheridan Computers @sheridan.co.uk · 09/07/2025I don’t take numbers too seriously, but if even one of those views helped one person overcome a challenge, fix a problem, or feel a bit less stuck, that’s more than enough for me. 000

Sheridan Computers @sheridan.co.uk · 12/06/2025Milestone for #Willow #RMM: After weeks in the #Rust backend, the agent/server architecture is solid. Now the React + Vite frontend begins, first time anything visual. This is where shit gets real for the #MSL space. #OpenSource #React #ITSupport #ThisIsHappening #ShakingItUp 020
Sheridan Computers @sheridan.co.uk · 06/06/2025We maybe the smallest #MSP Netgate, pfSense (or anyone else) has ever heard of, carry on pissing me off. I contributed the shit you hide behind a paywall that's part of #freebsd to your biggest competitor #OPNsense, for free, and the @tailscale.com plugin. Last chance. ¯\_(ツ)_/¯ 000
Sheridan Computers @sheridan.co.uk · 06/06/2025You have to love Netgate owners behaviour on Reddit. Spent 2 hours covering pfSense 2.8 release to get the 🖕. Checkout the video, if you see nothing wrong, a great reason to checkout @opnsense.org #pfsense #opnsense #freebsd #opensource 030
Sheridan Computers @sheridan.co.uk · 31/05/2025Working on a self-documenting command registry for my Rust-based RMM. Every command has descriptions, args, examples — all in code. Single source of truth → docs, API, UI, all in sync. Screenshot says the rest. 🦀 000
Sheridan Computers @sheridan.co.uk · 20/05/2025first rust crate out in the wild: windows-dpapi, a minimal safe wrapper for windows' built-in encryption (DPAPI) store secrets tied to the machine, no extra deps, just works wrote it for my RMM project (Willow) docs: docs.rs/windows-dpapi code: github.com/sheridans/wi... #rust #opensource 010
Sheridan Computers @sheridan.co.uk · 17/05/2025RMM agents aren’t just tools — they’re targets. I built Willow, a secure-by-default RMM agent: 👉 Single static Rust binary 👉 No DLLs, no side-loading 👉 Open source at MVP Security must be built in — not bolted on. #RustLang #CyberSecurity #RMM #Infosec 000
Sheridan Computers @sheridan.co.uk · 16/05/2025Benchmarking Willow (my open source RMM) against comnercial vendors... If Willow is 7MB, statically compiled, signed, and fully functional as an RMM agent, then wtf are other vendors doing with that extra 90–200MB+? #RMM #OpenSource #MSP #Willow 010
Sheridan Computers @sheridan.co.uk · 16/05/202548 hours wrestling and debugging Windows services and ConPTY in Rust almost broke me, but now Willow’s remote shell is rock-solid and production-ready. 💪 #RMM #MSP #OpenSource #Rust 010
Sheridan Computers @sheridan.co.uk · 13/05/2025You may have heard about an open source RMM I've been building, in rust. It's getting real, and it has the potential to massively disrupt the used car sales people pray on MSPs since their industry died. #MSP #farming #UsedCarSales 000
Sheridan Computers @sheridan.co.uk · 07/05/2025Building an open-source RMM in Rust: Self-hosted. WebSocket. Script exec, live shells, hashed inventory sync. Scales to 10k+ agents. No fees. No cloud. This will turn the MSP industry upside down. #MSP #OpenSource #RMM #ITSupport 010

Sheridan Computers @sheridan.co.uk · 05/03/2025Light mode or dark mode? 🌗 The website needed some love and updating of #laminas components, so I gave it dark mode as well - because I can't do anything without getting distracted.
