🌎 My Weekly Founder's Coworking Day is going global! I'll be in 🇸🇬 Singapore and 🇹🇭 Bangkok soon, and I'd love to host my weekly coworking day for founders there! If you're interested to join let me know, and if you know a good venue also 🤝 😊

What's easier than trying to build a giant furniture library? Letting users just upload their own furniture they want as a photo and then turn it into a 3d object in less than 30 seconds with an image-to-3d model ofcourse!

Noo I asked Claude what to use 100% free and it said OBS with a circle mask on the webcam It even made the circle mask for me 😃

✨ Progress update: I imported the entire catalogue of @IKEA in 3d into Interior AI after seeing someone do the same yesterday, I'll try to import more furniture brands soon to get more variety too Anyway so now you can import your home's blueprint or do a walk through video, it then rebuilds your home, and then you can redecorate it This is now day 4 of rebuilding Interior AI now that's the models are smart enough to do 3d stuff properly, it still looks a bit clunky and all but it's going somewhere! 😊

All the people on here always tell me for years "nooooo you can't just ship solo and have high uptime like big companies" And it's just not true, because big companies like Revolut even make stupid mistakes like not having monitoring working on their main production databases! And big companies go down all the time as you saw with Microsoft this week too The point being is that anyone can go down, and it's pretty equal for a well managed solo founder as it is for a big company

I got the Anker Prime 160W charger for my MacBook Pro to replace the gigantically huge and ugly (and white???) official Apple 140W charger The Anker one is cool because it's tiny, is dark gray (fits the Apple black cable), has 3x fast charging USB-C ports so you can also charge your phone and another device with it at the same time I love everything Anker makes so much Not paid or sponsored btw just an absolutely excellent brand Maybe Apple should acquire them?

More progress! Interior AI 3D works with "just" a floor plan now Not much information to work with and it has to imagine furniture etc. but it works Some weird things like the big I guess sliding windows to outdoor garden are missing, and bath tub is just a box, and I don't see a toilet seat etc. so we need it to become a bit more granular/specific/advanced But it's very promising It was really impossible until recently do to floor plan to 3d automatically and properly!

And this is with lighting probes as suggested by @threejs @mrdoob Pretty good for an AI reconstruction of a walk through video generated in 5 minutes on a VPS I think! I think today I'll make a demo video how the whole thing works and put that on http://interiorai.com's landing page as it seems I can pivot the entire product to this and grow it again This seems way more powerful than just basic image in image out restylings If you have any idea what to add, let me know! 😍

"And everyone liked that"

Tried this and it looks a lot better! WebGPURenderer r187 + SSGI + SSR

Tried ThreeJS shaders, very cool but very slow but very cool!

This is so realistic I'm not even kidding

All my feature dreams for Interior AI are coming true now :D One idea I had was to let you upload your own wallpaper and set it, it was a pain to even get an image model to put that properly With a 3d model it's much easier, so now you can walk around you room, upload a wallpaper texture and add it to any wall or object And you can set the material of any object too When you're done press [ ✨ Render ] and it becomes a photo!

Added this hover [ 🎨 Style ] menu so you can preview styles very quickly in 3d When you like one you press [ Render ] and you get the photorealistic version! Next I wanna try if I can make it do a walkthrough in 3d and then pump that into a video model like Seedance to make it photoreal too Then we'd have the holy grail, a full photorealistic walkthrough of your interior redesign 🤯

Claude also made this little landing page demo for the new feature

Added a [ Render ] button so your 3D perspective of your interior redesign is instantly (well okay it takes 20 seconds) transformed into a photorealistic render within Interior AI!

✨ Improved the video-to-3d viewer and editor interface now, so it's easier to move around or remove furniture now I also added lots of interior design styles, you can just tap and it changes all the colors in your room Also added floor plan mode (maybe I need a real official floor plan export later?) It just all works remarkably well All from just a walkthrough video you upload 😊😊😊 Live on Interior AI now!

Ok I stand corrected It seems stray RF accidentally using the wire of your headphone as an antenna ending up in your head was the case some years ago but not anymore They fixed it by spreading the antenna around the frame of the phone, TIL!

RT Channing Allen Re @levelsio

Wouldn't it be something if this was the thing that would pop the AI bubble

Okay it works, I can now upload a video or some photos or just a floor plan of my living room And then: - empty it fully - move around furniture - remove furniture - paint the walls, floor, ceiling and any object in any color Next: - top down floor plan view - change to any interior design style with one-click - integrate it into 🏡 Interior AI fully as a feature Very very very cool 😍🤟

There wasn't much technology to work with in terms of interior design with my app 🏡 Interior AI the last 12 months For 4 years it's been based on simple image models: photos of your interior as input -> redesigns out as output But now there is a completely new dimension to it 😬 As you probably saw on your timeline, AI can finally generate headless Blender 3d scenes from just a rough video (which I did today of my living room), or even a few photos, and even a floorplan (which no image model was able to understand before, believe me I tried 100 times!) That means that 3d scene I can then make fully editable in my app Interior AI Meaning you can paint any wall, floor or ceiling any color, next move around, delete or add new furniture etc from a giant 3d library of furniture Endless possibilities!! I think I found my next big feature 😍 I'll try get something live in Interior AI within the next few hours!!!

More than ever it'll be important to get your business as lean as possible I think Moving from expensive PaaS platforms to your own VPS is usually 100x to 1000x cheaper: Vultr VPS is $2.50/month AWS Lightsail VPS is $3.50/mo DigitalOcean VPS starts at $4/month Linode VPS starts at $5/month Hetzner VPS starts at $7/month Yes that's an entire server you can host your sites on! Add free Tailscale + free Cloudflare Tunnel + close all firewall ports and you're safe too!

Intermediary conclusion for now: Most of the good non-fluoride hydroxyapatite toothpaste like Nobs, Boka and Biomin are only sold in the US as most Europeans are blissfully unaware of the problem with fluoride Trying to buy it on Amazon Europe you pay like 5x to 10x the price, if it's available at all, it's crazy! Guess we have to fly to 🇺🇸 America again

Very interesting... 🇨🇳 Foshan for custom furniture!

I think many people are underestimating basic economics If something is 5x cheaper to buy and it's personalized (aka better) it'll be worth it Also you've ever ordered something from furniture brands these days? Service is non-existent and everything is delayed because of labor shortages, on top of that two of the furniture companies I ordered from went bankrupt after we got our orders! We're in the era of personal software and as an extension of that personal hardware, with kind of a second maker wave happening, because now it's suddenly become accessible to design and build hardware for almost everybody, thanks to AI The question here is will suppliers (mostly in China) also start doing custom assembly and shipping it worldwide, many already do but this seems a market they could jump on Many furniture brands are essentially dropshippers for products made in cheap countries anyway. Even the fancy Italian brands mostly produce in Eastern Europe and China! So all you're doing is removing the intermediary I think 🤔

Massive market maybe opening up now for woodworkers and carpenters etc to put stuff together that people design themselves with their AI agent and then buy raw materials from suppliers

Claude Code can design furniture part by part and then give you a bill of materials to order each part and put it together yourself And way cheaper than big interior brands sell you their furniture Furnishing my house I discovered how absolutely insane prices are for the most basic cheap materials put together with a fancy brand tied to it One shop had a sofa for $30,000 😂 I think with Opus 5.5 and other models easily operating 3d programs like Blender and FreeCAD (both free) it makes more sense to cut out the middle man and go straight to suppliers and design and build your own furniture Which in a way makes customers more powerful (they can get exactly what they want and usually for cheaper without the markup) Anyway @theannalux designed this table from scratch, she's not a furniture designer, not a coder, she just had an idea of a style and worked with Claude Code in the terminal (far superior to the app I will keep saying this) If you design your own furniture and buy the raw materials directly, you can save 85% compared to premium brands like Poliform That means the $30,000 sofa becomes $4,500! And the $8,000 dinner table becomes just $1,200! You can see where the idea comes from that AI will make everything 5x to 20x cheaper, and it's already starting!

⭐️ Added nickname reservation on @pieter for all games and also for the emulators and IRC Once you have your nickname reserved you can use it everywhere and nobody else can On IRC it has the famous NickServ and you type your code to unlock your name And on Windows XP and 3.11 it will let you save your files so you can use it as a real computer with a real hard drive, so if you come back your files are still there like a real computer! Also I think I can add email box in future too so people can email each other inside the emulators (right now it just emails internally from web@ to web@ only) Can reserve your name here (I tried to make it look like the Cloudflare Wallet card 😊): http://pieter.com/me

One of my biggest motivations to make web games (the original motivation for my fly-pieter-com game) or port existing games to the web is how incredibly slow the loading times of modern games have become I have an RTX 5090 w/ 32GB GDDR7 liquid cooled maxed out gaming PC with 128GB DDR5 RAM, a 16-core 32-thread AMD Ryzen 9 9950X3D and a Corsair 4TB NVMe SSD And it still takes almost 3 minutes just to load Flight Simulator, and that's after loading it a few minutes before already to install the updates You can call me impatient, but you used to just put you'd run a game and you'd start playing within 30 seconds or instantly! That's how it should be I think!

iOS 27 has broken the amazingly useful Low Light feature (inside Zoom) combined with Smart Invert If anyone works at @Apple, or knows anyone there, it'd be amazing to get this working again! Bug report and prompt for Apple staff to copy paste into their clanker to fix it: "## Bug: Zoom "Low Light" filter + Smart Invert makes the screen brighter instead of darker (regression in iOS 27) ### Summary Before iOS 27, turning on Smart Invert together with the Zoom filter "Low Light" made the screen very dark. Many users rely on this to read at night, like a Kindle. In iOS 27 the same combination makes the screen noticeably BRIGHTER than Smart Invert alone: the background looks washed-out light grey and the text is full white. ### Steps to reproduce 1. Settings → Accessibility → Display & Text Size → turn on Smart Invert. 2. Settings → Accessibility → Zoom → turn on Zoom, set Zoom Filter to "Low Light", Zoom Region to Full Screen, and zoom level 1.0x (or the lowest possible). 3. Open a white page, e.g. Safari or Books. 4. Compare the screen with Low Light on and off. ### Expected (iOS 26 and earlier) - White background → near black - Black text → dim grey - Result: darker than Smart Invert alone ### Actual (iOS 27) - White background → light grey (~70%) - Black text → full white - Result: brighter and lower contrast than Smart Invert alone ### Likely root cause The order of the two filters seems to have been swapped in the display/compositing pipeline. - Old order: Smart Invert → Low Light (invert, then dim) - Output = 0.3 × (1 − x), which is always dark - New order: Low Light → Smart Invert (dim, then invert) - Output = 1 − 0.3 × x, which is mostly bright, because inverting a dimmed image turns the dimming into brightening The washed-out grey look is the typical sign of dimming before inverting. My guess is that a refactor in iOS 27 moved Smart Invert into a final full-screen pass, or moved the Zoom filter earlier in the chain, so Low Light now runs underneat...

I present you my... @X Reply Bot Super Laser Cannon

Eerily quit in my replies and suddenly no AI bot replies anymore 😂 I think some people at least got the message?

The worst part about AI replies it's a negative cost to all of us on here You squeeze out people who actually put effort to interact with others on here For some dumb growth strategy that doesn't work anyway TL:DR: if you're doing AI replies, you're an asshole

I will publish my full list of 10,000+ blocked AI spammer accounts soon so everyone can block them easily tooo If you write AI replies under my tweets you will now permanently destroy your X account Because you'll very quickly end up in a public data set of AI spammers that people will use to block them Better turn those AI reply bots off today

Great list of AI spammers Ask Claude in Chrome to block everyone in this list https://x.com/i/lists/2116659176894071283

I will collect all accounts I blocked for AI spam recently and submit them to @dillon_mulroy's list too I will also send my entire list to @X staff so they can suspend the accounts If you post AI replies under my tweets I will now go nuclear on you Only way to keep this platform usable

I did the same a few months ago I shut down my 13-year old $300/mo Linode VPS server that hosted all my 100+ sites for over a decade! That Linode VPS called Tommy is where everything started for me, I knew to build startups I needed a server so I just made one and SSH'd into it and started uploading PHP files of little startups I made After 1.5 years my first sites started taking off and I started making money on the internet with Tommy! For almost a decade I'd still FTP my files by dragging them every time I made an edit to the server, only around 2020 I switched to Github because @daniellockyer said it'd be better and because regularly the site would break at halfway because people would load the site while I was in the middle transferring index.php over FTP 😂 I didn't have multiple VPS servers, I had just one for ALL my sites and projects (I'd say upwards of 100), but it worked mostly fine, and I regularly posted about how it was all on one server which made Twitter/X go crazy "how do you scale???", it scaled fine, served 300 million people per year and 115,000 paying customers in its lifetime! Back around 2013, Linode was the "cool" hoster on Hacker News, but a decade later, the spirit of Linode seemed to have disappeared, it felt like it was in maintenance mode and not really loved for anymore. When it was acquired by Akamai in 2022, me and @daniellockyer knew we'd have to leave because acquired companies generally go to shit I saw @DHH posting about @Hetzner_Online so I started making little VPS servers there to test it, first with @pieter and it worked really great. Then slowly I started migrating each site over to Hetzner, with the most critical sites like Photo AI and Nomads last. I also started separating sites on to different VPS servers, isolating them, which now in this new AI cybersecurity time makes security sense. It was never an issue with performance though to have 100+ sites on one VPS, like literally never at all Then a few months ago I ...

Many of my friends like @csonotes and @NorbertDragan devoutly believe we have to go outside more and I think AI will help us to :D

"here's a complete regurgitation of your post but with strong AI tells." Exactly why AI replies suck

Even with this on on all my posts I still have to block like 50 AI reply accounts per day, it's getting crazy on here I think it's because @SpaceXSI lets you let Grok use your X account It's crazy cause now they post shitty AI replies on regular accounts of people that the people I follow (aka "accounts you follow & who they follow") I DM'd a few of those ppl I follow that they follow AI bot accounts but of course it's a drop in a bucket It'd help if AI replies actually added something to the convo but they don't, it's always some basic shit like "paying bills is where every agent demo dies" or "claude wrote a whole graphics layer and the only leftover bug is that phones are vertical" ???

Fixed the mobile stretched interface on portrait mode in BF1942 by modding the engine Claude Code told me how it did it: "1. Spotting the HUD: 3D world draws use a perspective projection, where far things look smaller. The HUD uses a flat one. I can tell them apart from the projection matrix the game sets before each draw. 2. Measuring each element: before drawing a HUD piece (the ticket count, the map, an ammo icon), I calculate on the CPU where its corners land on screen. That uses the same matrix math the graphics card would do. 3. Squeezing it back: I shrink its height by that 2.9× factor toward a fixed edge depending on where it sits. Things at the top move toward the top edge, things at the bottom toward the bottom edge, and things in the middle toward the center. Because everything in the same band moves together, the map and its icons stay lined up. 4. Leaving some things alone: big panels, like the scoreboard and loading photo, keep the old stretch so their layout isn't changed. On menu and loading screens, text shrinks around its own center so tap areas don't move."

Any way we can auto pay bills with @Revolut? Claude won't do it: "I can't do that, even through Chrome. I don't send money or make transfers, even when you ask and even in a browser where you're already logged in. That's a fixed rule for me, not a technical limit." Also Revolut still doesn't have any publicly usable API right? Only this fake banking API that's only for verified enterprise companies?

I managed to port Battlefield 1942 to mobile web too So now it's playable as full multiplayer on iPhone and Android from their browser! 🤯 Claude Code built its own graphic layer that translates Direct3D (DirectX) instructions to WebGL, sitting between the game's machine code and the browser, which means we can change the resolution any way we want! Only issue is you get some stuff cutting off (like the arms below or inside vehicles) because the game was never meant to run in portrait mode of course!

Okay I just upgraded Battlefield 1942's game and server from v1.0 (the demo) to v1.61 (the latest version) on http://bf1942.pieter.com That involved another round of decompiling it and lots of new bug fixes to make it work in the web on multiplayer But it works now and the game is much better now, v1.61 came out in 2004, two years after the original v1.0 The gameplay is crazy and intense and this is essentially the godfather of every modern Battlefield and Call of Duty game Max players now is 64, come play! I recommend Chrome on your laptop!

That's kind of the problem with X (or not) It's a bad platform for sponsorships because (for me at least) it's about being as direct, transparent and honest as possible with your "audience" Also it's not really an audience, it's more like a big internet forum I feel like where you can have cool discussions The moment you take a sponsorship, the companies pay a lot of money for you to say something specific, that's probably not really what you believe in completely Your followers immediately can sense that's not your own voice and cringe and very often unfollow, I mean I know I do for sure But if it's a YouTube video it's kind of accepted "this video is sponsored by ACME, Inc.", nobody cares and it's just a few seconds in a 10 min video anyway so it's fine, it doesn't affect the content usually That's hard to do on X because look at this tweet, it'd just be hard to fit in a sponsored message here that doesn't sound supercringe!

Decompiling Battlefield 1942 and then porting it to C and then WASM cost me 1 million output tokens At API prices that's about $100 But I pay $100/mo Claude

I decompiled probably my favorite game ever: Battlefield 1942 and I put it on the web with multiplayer for you to play here: 👉 http://bf1942.pieter.com 👈 (It's the free shareware demo) It was way harder than the other ports like Quake and DOOM I did because they already had lots of open source projects and work behind them In case of Battlefield 1942 there was literally absolutely nothing to work on top of, nobody had ever ported it and there was no open source engine for it, nor did the makers ever open source it (like id Software did with Quake 3) I tried it 6 months ago and essentiay gave up but I tried it today again with Opus 5.5 asking "can you try port the BF1942 demo in this folder to web" So me and Claude Code (well let's be honest mostly Claude Code) did crazy shit today: - it disassembled the x86 raw machine code to find 57,000 x86 functions - it translated each x86 function into a C function (mov eax, [esi+0x110] becomes eax = READ32(esi + 0x110), I have no idea what any of this means btw) - it outputed 100,000 lines of C - it then compiled that to WebAsswmbly with Emscripten - there were 300x Windows and Direct3D functions used which we had to rewrite to WebGL 2 and OpenGL to work on the web - then we had to build our own network stack so it could connect to our multiplayer server via WebSockets I have no idea how it did any of this but it did it and it seems to work! 😊 Come play and report any bugs here!

My friend @stevelacey says AI agents almost never use MCPs if they have it available I thought the same before which I was against MCP so long I always thought APIs could do the same already, in the back they're almost exactly the same Long term I think MCP and API endpoints will just merge into one, both supporting API keys and OAuth account level access I have been adding MCPs to my site simply for the fact that people expect them now but as Steve says it's debatable if AI agents actually will use them over whatever other way there is to use your site

Okay I hit a bump decompiling the multiplayer part
