Hot take: If you're writing ImGui-style code in C++ without any kind of code hot-reload, you're holding your computer wrong.

No no no, Sony shuts down Bluepoint? I'm sorry for everybody at Bluepoint, that really sucks. Guess it's that time of year again until end of March, probably lots of news like this to come :(. www.bloomberg.com/news/article...

We've just released a new Insider update with some much-requested features, like being able to specify env vars when running, auth support for symbol servers, and proper progress reporting for symbol downloads. And of course, many fixes & QoL improvements. Go check it out!

oh.... my god?? actual chart from learn.microsoft.com/en-us/traini... btw

AI slop paving its way through codebases like the cancer it is.

Reposting this for the European crowd. Please repost and share among friends, peers, coworkers - I'm trying to gauge if this has merit to be continued or not.

I've been working on something new since August 2025 and have decided to finally spill the beans: Introducing "Project Echo", a deterministic Record & Replay tool for PS5: www.youtube.com/watch?v=K_sd... Please read the video description and let me know your brutally honest feedback!

Automatically showing latest build ID from e.g. Perforce: 1) Simple .bat file that writes a .txt, build step in Visual Studio 2) A few string views that point into the .txt 3) Render to screen 4) Profit! Sometimes it's the little things. #cpp

Currently preparing a slide deck, looking through some older stuff. Came across these two pictures from GDC 2019. I'll be blunt: the fact that Epic Games announced licensing Live++ in their "State of Unreal" and showed it at their booth still completely blows my mind.

New blog post: Phase 0: Motivation and goals liveplusplus.tech/blog/posts/2...

Had my first real use case for C++ "volatile" in a long time. Need to wait for an event to happen to unblock threads, but cannot talk to the process (=devkit) in any way, only from the outside (=PC). Event to happen is set by changing a certain memory location from the PC.

Thanks for that amazing feedback, keeps me motivated!

I think most game dev teams underestimate how damaging slow workflows are to the ultimate quality of their game. If it takes 5 minutes to launch the game and see your changes, I think your game is going to be MUCH worse than the alternate timeline where it took 1 minute

For what I'm working on, I can change every file, asset, shader, and C++ code and see the changes in <1s. Shaders take roughly 100ms, C++ code 500ms. Using my own custom tech and Live++.

To me, Mathias Gidsel really is the GOAT. Such joy watching him play. 6 assists and 7/7 against that defense. Just amazing how agile, dynamic and intelligent his play is.

Ever wrote spin-locks or had to debug them? I have, and I got tired of seeing (and writing) crappy ones, so I did a real investigation this time. Spoiler: trust your OS. siliceum.com/en/blog/post...

I guess we are doing this again: liveplusplus.tech/blog/ Expect a mix of low-level, C++, assembly.

@jbikker.bsky.social Just wanted to say thank you for your ray-tracing blog series. I needed a refresher for how everything works underneath, and your articles were super informative and well written. Thanks!

Started working on a bit of game/engine tech over the holidays, had a look at Molecule. Found some good bits, but am also on a completely different experience level now. Whipped out a completely async, jobified, hot-reloadable asset manager using I/O completion ports in 10 hours.

Can I just get everybody to read this blog post and apply it to their own programs? randomascii.wordpress.com/2016/05/12/u...

Preparing the traditional veggie broth for the Christmas soup. Happy holidays everyone, see you in 2026!

New article! What do you do when profiling your code shows the slowdown isn't in your code, but deep in the kernel? Why, you grab the kernel source and go spelunking. How a routine profiling session turned into a Linux kernel patch: rovarma.com/articles/fro...

Most likely the last update of the year. I have some great things in store for you for 2026 :).

Surprise! Live++ hot-reload running on SteamDeck Proton. This is a debug build with the SteamDeck connected over Wifi. Final performance will be <1s reloads.

MSVC linker bug reported here: developercommunity.visualstudio.com/t/VS-linker-...

Oh no no no... Investigating a customer's bug report. The PDB just came in, and after a day of looking at RVAs, symbol names, .objs, relocations, I finally saw this (note the addresses). And how's your day going?

Tried my new SteamDeck today. Impressed by how easy it is to set up and run Windows executables via Proton. Of course, Live++ uses esoteric internal Win32 APIs that apparently don't work, so I can't hot-reload on the deck (yet).

Ever wondered how to store millions of call stacks efficiently? So did we. Many times. Check out this new article by Jelle about designing a data structure to efficiently compress and store large amounts of call stack data! superluminal.eu/compressing-...

I've been asked quite a few times lately how certain things in Live++ work underneath, e.g. PDB loading, string lookups, performance, testing, hookikg, etc. that I think it would maybe be a good idea to start blogging again. What do you think?

learn.microsoft.com/en-us/cpp/ov... /DEBUG:FASTLINK is gone. Rejoice!

This is not how I envisioned my day today: github.com/slynch8/10x/... What a rabbit hole. First time I've ever wanted a real-time .bat debugger in my life. If you're a 10x subscriber, you can find some details on the Discord server.

Not pictured: The rack to the right of my desk, with 6 devkits, a bunch of controllers, a monitor, an HDMI switch, a 16-port switch, and a SteamDeck.

Office desk upgrade.

Hot take: building your software for a certain OS should require *nothing* that isn't already there out of the box, and/or work with the most popular tools/IDEs. If I want to build your software for e.g. Windows, ideally it has .bat scripts and/or a VS .sln.

Hey @code-disaster.bsky.social, can you DM me? I've been trying to reach you today, but mails keep bouncing :(.

There is some traction currently on a proposal I made for the Visual Studio debugger: developercommunity.visualstudio.com/t/Consider-add… If you're a user of Live++ and/or .natvis in general, please consider commenting and upvoting. Thank you!

Why is *every* company on this damn planet shoving down AI our throats? I cannot tell you how mad stuff like this makes me.

Terry Pratchett's writing of the Nac Mac Feegle accent always makes me smile. It's so perfect, I can hear a Scottish voice talk in my mind :)

Interesting read with some explicit numbers: www.theringer.com/2025/11/04/t...

Hi folks, this is again a plea for help. There still is no cleared donor. People working through the system but again-if you're at all interested in trying to help, it takes months to get cleared as a donor. There's a lot of delays/appointments. So please consider and spread it around, thank you.

I am afraid I have absolutely terrible news. I need a lot of help now, from everyone. I currently have NO CLEARED DONOR for transplant and we only have a short period of time to get this done. Please SHARE THIS WITH EVERYONE AND PLEASE TRY TO DONATE! All the information is at iggyland.org

A plea for help. 🙏 One of the lead playtesters of Blue Prince, Iggy, has polycystic kidney disease and has only a few months to find a living kidney donor. His story, contact and donor information can all be found on iggyland.org Please help us in sharing his story and getting the word out.💙

Iggy was an invaluable tester and contributed so much to the project. He was absolutely brilliant in the game and came up with so many original strategies we had never considered. Please help us spread the word and as we help find him a living kidney donor. 💙

Łukasz from Wookash Podcast (@gameengineering.bsky.social) has posted a lengthy conversation I recorded with him a few weeks ago: www.youtube.com/watch?v=2KPU... It's really awkward for me to watch it so I'll assume it's just confused rambling :)

Is your company interested in trying Live++? Want to know what it can do for you? Curious about its features? You can now request a live demo through our website - free of charge! liveplusplus.tech/request_live... #cpp

Do you want to improve the performance of your il2cpp Unity projects, without changing your code or your assets? My il2cpp build processor cpp2better is now officially available (on request). Reach out to me, details here: blog.s-schoener.com/2025-11-04-c...

Thanks for having me, Mojang! The talk was fun, I enjoyed doing it, especially the numerous "Live++ meets DOOM" live demos.
