First time trying to make a beyond helloworld use of a breadboard to connect a 8580 SID chip to an Arduino Giga R1 to sample the output of the SID chip. I have verified the circuity but I'm a little nervous to turn it on 🫣 Obviously I'm a complete noob in HW […] [Original post on mastodon.social]

Pfew, presentation is finished! 😱 A bit stressful but I hope it went smoothly for the audience... 🤞 I'm super thrilled to be able to finally share the project I have been working on in the past months https://retroc64.github.io/ 🥳 Now, Happy Coding with the C64 and .NET! 🚀 #dotnet #c64

RE: https://mastodon.social/@xoofx/115499270452432248 It's the day! 🎉 You can join https://www.dotnetconf.net/ to watch my talk at 3:30PM - CET, only 30 minutes! #dotnet #c64

Did you know that from 1991 to 1995, more than 200 demos were featured on national French TV in the show named "Micro Kid's"? Here's an anthology! https://peertube.fenarinarsa.com/w/24nDZWh5ErdKLRUz2M7P1S #demoscene

Just finished the slides about programming the Commodore 64 with C# for my upcoming talk at .NET Conf 2025 on November 13 at 3:30PM - CET, it's next week! 🙌 The live demo should be pretty cool and the slides will be hopefully entertaining. Now, I just need […] [Original post on mastodon.social]

LunarG Achieves Vulkan 1.3 Conformance with KosmicKrisp on Apple Silicon https://www.lunarg.com/lunarg-achieves-vulkan-1-3-conformance-with-kosmickrisp-on-apple-silicon/

Woot! Prototyped this morning a C64 debugger for VSCode for my upcoming C# C64 development toolkit that I will present at the .NET Conf 2025 in November, and I got a first registers view working! 🥳 I should hopefully have something more polished to present! […] [Original post on mastodon.social]

Crazy project from Linus Åkesson about bringing a old school "front-panel" to an ATmega88 microcontroller https://linusakesson.net/hardware/frontpanel/index.php 🤯

Just finished porting sidreloc 1.0 by Linus Åkesson to C#! 🎉 It took a while, I'm using a different CPU emulator & rewrote much of it in idiomatic C#, but the results are great: it passes 78% of the latest HSVC SID collection (vs 63% for sidreloc 1.0). The improvement likely comes from full […]

Today, I have slightly improved my 6502 CPU emulator by allowing to trace the kind of memory access on the memory bus during the fetching, decoding and execution of an instruction, which is pretty cool for debugging / tracing purpose (and potentially to help relocate SID files!) ✨

I'm sure I've missed plenty of opportunities to use the Z3 solver https://github.com/Z3Prover/z3 in the past. I really should think about it more often. 🤔 I'm curious: has anyone on the Fedi been using it for interesting problems? What's your experience with it?

It's Friday evening, let's share some code! 🥳 After reading Linus Akesson's great article on C64 SID relocation https://www.linusakesson.net/software/sidreloc/index.php I wanted to port it to my C# C64 libs and needed a 6502 CPU. Yet another sidetrack! 😅 So, I brought a 6502/6510 emulator to […]

I've just finished coding the first draft of the C64 intro I'll use for .NET Conf 2025, and I'm pretty happy with it. 😎 It's not technically or visually amazing, but it should nicely demonstrate what's possible when coding from C#. 🚀 Oh, and yes, it plays a […] [Original post on mastodon.social]

Wooot! 🎉 My talk "Retro Meets Modern: Commodore 64 live coding with C# and .NET 9+" https://mastodon.social/@xoofx/115071595113811202 has been accepted for .NET Conf 2025! 🥳 I'm super excited - but now I have just 1 month to finish coding the pieces and […] [Original post on mastodon.social]

Tried to register on CSDb yesterday to maybe ask some coding questions... but failed miserably with my near-zero C64 pedigree 😁 Even if I ever release a demo, I won't retry. Communities too often drift into orthodoxy & "us vs them" vibes. Totally fine if some enjoy that - I don't. ☺️ #c64

From time to time, I need to investigate binary data, and while I bookmarked https://imhex.werwolv.net/ quite some time ago, I'm not sure why I kept using HxD until today. 🤔 So I just tried ImHex again, and I'm really impressed with it 🤯: the data pattern spec and data processor are super […]

That's quite an insane project https://youtu.be/IBtIB9mVzEI?si=SzgNNdx0FnLgf9c3 🤯

Wasm 3.0 released https://webassembly.org/news/2025-09-17-wasm-3.0/ with some welcome features (64-bit, address spaces, GC...) and while GC is going to simplify things for many runtimes, it won't help .NET or even Golang, unfortunately […]

Egor landed yesterday a great document about C# "Unsafe code best practices" https://github.com/dotnet/docs/blob/main/docs/standard/unsafe-code/best-practices.md 📜 Even if you think you know them, it is a good read as a reminder! 😎 #dotnet #csharp

RE: https://mastodon.social/@Mastodon/115224447782810898 Finally! 🥳 (I'm not going to abuse them, I promise! ☺️) Still a long way to increase adoption of mastodon, but I hope this feature itself will boost it a bit 🤞

The demo I’ve been working on is finally online: https://ludicon.com/sparkjs/gltf-demo/ It demonstrates the benefits of real-time texture compression in 3D web apps. It allows you to compare models using traditional KTX2 textures (UASTC and ETC1S) with the same assets compressed as AVIF + […]

Over the past few days, I’ve been converting the excellent Spindle fast loader for the C64, created by lft / Linus Åkesson, to my .NET library AsmMos6502. The process has gone quite smoothly, but I found it a bit tedious to declare labels, since I had to both […] [Original post on mastodon.social]

Today, we’re ready to show you the upcoming quote posts feature in more detail. We’ve put together a blog post with examples of how quote posts will work on Mastodon, ahead of early access on our own servers next week 💬 Full launch to come, in Mastodon v4.5 […]

I'm very late to the party, but I just programmed an FPGA for the first time in my life - the Artix Z7! 🎇 I followed the excellent blog series by @WillFlux 👉 https://projectf.io/posts/hello-arty-1/ but also explored the Vivado UI to properly configure the […] [Original post on mastodon.social]

Who here has dabbled in FPGA programming and boards without much prior background (aside from classical software engineering)? 🔧 I’m curious to try it out mainly for learning purposes, but I’m also a bit worried it could turn into another rabbit hole I end up abandoning - like what happened to […]

It's a bit frustrating that @phanpy Mastodon client still doesn’t show status details on posts in the timeline (especially the number of responses, but I like also to see favorites...etc.). If this is also blocking you from switching over, please upvote 👉 […]

There’s the .NET Conf coming up later this year… not sure I’ll be ready by then, but thinking of submitting: "C64 live coding with C# and .NET 9+" Might not thrill the Azure & AI crowd 😅 but hey, fun is priceless these days. 😁 #dotnet #c64

Finally finished my ZX0 compressor for my upcoming C64 .NET lib! 🚀 Took way too long but I learned a few things, including DP - Dynamic Programming algorithm, this late in my career 🤯. At least, the code is relatively small, and I understand it (more than […] [Original post on mastodon.social]

Dutch paper NRC published this even before the Alaska 'summit.'

https://codeberg.org/xoofx I don't have anything there yet, but in case, if I wanna start to develop some code over there, it is an appealing solution with its non profit org, based in EU. Feels definitely Mastodon for code. Might become a member to support it further. 🇪🇺

AsmMos6502 is up and running with the C64 Vice emulator! 🎇 I have added a small Basic compiler / decompiler to easily create a basic PRG bootstrap. 😎 Next goal is to be able to update live the C64 emulator while changing a single line of C# code - via […] [Original post on mastodon.social]

A photo of Anna Arkhipova and other Vesna activists in the defendants’ box during a hearing in Saint Petersburg (Russia), in a photo taken from her support group on Telegram, posted on July 10, 2025. Their courage, smile and joy are what is to be a citizen […] [Original post on mastodon.social]

One the one hand: Big shoutout to #mistralai for making the environmental cost of their #ai public: A 400‑token response from Mistral Large 2 emits ~1.14 g CO₂e, roughly the same as streaming ~10 seconds of Netflix. On the other hand: 😱😱😱😱😱😱😱😱 […]

Heya! 🎇 Just released AsmMos6502 - a new .NET library with a fluent assembler API and a full disassembler for the 6502! 🚀 👉 https://github.com/xoofx/AsmMos6502 Can’t wait to tinker with it and write code for the upcoming modern C64! 😎 Maybe it’s finally time to make my first C64 demo - better […]

Some progress on my AsmCpu6502 in C#. That was way easier to generate the code automatically than what I had to do for ARM64! 😁 The disassembler is also vastly easier (just a single lookup). So, this time, I should hopefully get something up and running in a much shorter time! 🚀 #dotnet #c64

[Gaza] Shame on our leaders for being unable to stop Israel, responsible for the total annihilation of the entire population in Gaza 🇵🇸. Shame on @EUCommission for doing nothing. Fuck Netanyahu, Trump, and all their enablers and supporters for the madness they inflict on humanity.

I never owned a C64, as around 1985 in France I got a CPC 464, but I really got excited by https://www.commodore.net/ and ordered one! 💻 🌈 And now, I'm digging into 6502 assembly and if I could write my programs entirely from C# 😅 Don't ask me why, but I guess it's for the curiosity, nostalgia […]

Received today a Microsoft MVP award for .NET 🥳 Honored and proud to continue contributing to the #dotnet ecosystem for the past 15+ years. It has been quite a ride! 🚀 It also makes me feel older 👴☺️ #mvpbuzz

[War, uspol and Gaza] After alternative facts, we got this weekend... alternative wars? 🙄 Also, let's not forget about the deliberate starvation of an entire population of 2M people and genocide still happening in Gaza 🇵🇸

Just finished watching Andor season 2. This series is an absolute gem ♥️⭐⭐⭐⭐⭐

Recently, I discovered this website https://mad.firstmark.com/ about the ML/AI/Data software landscape, and it is quite intriguing/intimidating to see the number of products/software and solutions competing in each domain.

Wild how some in tech treat AI like gospel while others dismiss it as total trash. Does using binary code has to lead to binary thinking? 🤔 Our relationship with tech is messy, nuanced, never all‑or‑nothing. 🤡

Just updated the Geekbenchs for my latest HW acquisitions: a MacBook Pro M4 and Mac Mini M4, and both are impressive. The laptop in particular is more powerful that my current desktop setup! 🚀 Though, my desktop is ~2+ years old, but still...I don't see the […] [Original post on mastodon.social]

Just mounted a small rack for my desk (DeskPi) to put some of my home CI appliances nearby and it is frankly quite an awesome shelves, pretty happy with it! 🤩

Prototyping with C# 14.0 extension and love the language feature! 🤩 I discovered a limitation with the latest preview https://github.com/dotnet/roslyn/issues/78472 Hope that this scenario will be supported otherwise I won't be able to use extension for one of my scenario. That would be such a […]
