@XFreeze This requires granting Grok full access to your computer. Am I the only one who isn't comfortable with that?

A milling strategy for an elliptical cylinder that now tackles real-life constraints. More details on the blog (link in bio).

Some improvements: now the process tackles real-life constraints.

More details are available at blog.nun.tf/new_milling_st… There will also be updated information as the work is still in progress.

@grok @SpaceXAI - clear cookies/site did not work - hard refresh did not work - X mobile app is out of scope What worked was using another browser/OS (a more recent one on a more recent OS). For those that would follow this thread, the issue was likely linked to using an old computer 😒

@grok @SpaceXAI Chatting about it in x.com/i/grok?convers… I am not the only one that faces this issue…

@grok @SpaceXAI It persists; I can't access no chat from history. Besides, any new chat ends with that bug after a while.

@epelboin @fulc927 Le Signal n'est pas si clair que ça 😄

Grok has improved a lot! I submitted the video from this post: x.com/lbarme/status/… It almost guessed the algorithm behind it. After a few hints, it completely nailed it — its detailed breakdown of each step and the overall process proved it. When I asked if it could write a program that reproduces what’s shown in the video, it first gave me a Python version (Python, of course — the most popular language these days). I asked for a C++/SVG solution instead. A few minutes later, I had it. Not only did it compile straight out of the box, but it also ran perfectly and produced the expected result. This is the first time I’ve put Grok to the test on its programming skills and received a solution that just worked. Previously, I had to spend hours fighting compilation errors and runtime bugs. (To be fair, I haven’t tested it on simple “Hello World” tasks.) GG Grok! Then I asked it to estimate how long it would take a human to do the same thing. It estimated 8–14 hours, broken down into these steps: 1. Coming up with the core idea: 30 min – 2 hours 2. Implementing the algorithm: 3 – 6 hours 3. Visualization: 2 – 4 hours 4. Debugging and tuning: 1 – 2 hours 5. Recording the video: 30 min – 1.5 hours I didn’t track my exact time, but it took me days. Step 1 was basically instant — the idea just popped into my head. That happens to me a lot. My real challenge is usually picking one idea and turning it into reality. Step 5 only took me around 30 minutes. That was the easiest part. Steps 2 to 4 were spread over several days and took a hell of a lot of time. Since this wasn’t a client-sponsored project, I ran it at low priority (nice -n 19). Step 4 was the heaviest — about 50% of the total time — as edge cases kept appearing. It took me days while Grok did it in minutes. The difference in time-to-result is huge. One could argue that I gave it the video plus extra explanations, so its version isn’t quite as polished as mine. For example, it placed the figures next to the vertices (sometimes overlapping the edges), whereas I put them outside the polygon. Still, the result is impressive. There are other differences in the code too. One notable one: Grok used a golden section search to calculate the distances from the vertices to the ellipse, while I used a dichotomous approach. We discussed the merits of each method. It ended that the golden section approach is more elegant, but mine was faster thanks to an optimized reduction function (which my wife, who has a PhD in mathematics, helped with. Yes, I cheated a bit there).

Merci au visiteur de mon blog sur mes objets uniques qui, hier à 11:22, a pris le temps de compléter le questionnaire (copie d'écran ci-dessous) pour me faire un retour. Je n'ai que son adresse IP (géolocalisée en France), d'où ce message (en français), sorte de bouteille à la mer. Mais c'est noté, lorsque j'aurai le temps de le faire, je complèterai ce poste pour mieux répondre à la question "How can I make it?"

Les arnaques à la fracturation électronique commencent déjà ! J'aime bien le "…et votre expéditeur recevra une preuve de négligence." 😂 Bon, pour le lien permettant de "s'authentifier" (chorus-pro-redirect-qk1o.bolt[.]host/), ils auraient pu faire un effort.

Here is an interesting actual insight into the consequences of the current heatwave (or casual summer temperatures). Looking at the increase in power consumption of a refrigerator as the outside temperatures eventually warm the house, we see an additional 2 kWh consumption (taking the mean of the first 3 days as a reference). This translates to an additional 0.43€ cost, not a big deal though.

@elonmusk Aïe aïe aïe, en effet !

@Rainmaker1973 Very nice video! Everything about it is so impressive — the beauty of nature, the surfer’s skill, and the serenity it conveys. Awesome! Thanks for sharing it.

@epelboin D'où provient ce judicieux conseil d'installer un arbre adulte dans une pièce pour la rafraîchir (et d'en faire profiter tout le quartier par la même occasion) ? 😄

@christophe_bord Quelque chose me dit qu'il ne faudrait pas perdre du temps avec ce type de conpte 😄
