Regular Sunday 10 miles here, then I had the pleasure to experience plantar fasciitis. I love running, but the injuries can be really annoying


I fixed my recurrent back pain with a 6 mn daily morning, ie. plank, side plank, reverse plank, 1mn 30 sec each.

Posture muscles are not very well known in the general public. Loss of strength due to aging and sedentary lifestyle makes standing, seating, etc uncomfortable.


The best posture is your next posture.

I'd say as long as you use all your muscles meaningfully everyday, and don't spend hours in a single position, you're good.


Significantly faster compilation means less friction to iterate ideas, try things, which in the end lead to more polished results.

A nice interface is agreable, but maybe there are diminishing returns when you pay it with large compile time. I remember pondering about that when working with the Eigen math library, which is very nice but such a resource hog when you compile a project using it.


A nodal real-time video processing tool : put together pre-made "processing boxes" to generate interactive video. It runs on pretty much anything, uses a plugin architecture.

Say, plug a camera, and it will blend two videos streams using a silhouette detected on the camera, with various effects. It's very, very early, pre-alpha stuff, but it already was used for a demo by a customer.

GitHub pestacle, be warned, it's undocumented and larval stage


Will it be something like TouchDesigner[1] ? I never used TD myself, but I follow a lot of creative types who do for making music visualizations, art installations, etc.

I can't find it on Github though, maybe repo is private ?

https://github.com/marmakoide/pestacle

Be warned, zero documentation, because things are at larval stage and change often. Will include a couple of demos this week.

In the spirit, yes, but targeting different hardware, public, and environments.

* It runs on Linux, Mac, Windows. Bare metal on rp2040 and rp2350 is planned.

* It written in C, build with Make.

* It is meant to run on something like a Raspberry Pi, Latte Panda, etc

* A setup is a text file, no fancy UI.

* The plan for live parameter fiddling will be a web server. Web UI will be tailored to each setup, no one size fits all UI. Typically I pay someone to do the UI.

* For now, it's only video, no sound output

It will be used for several large interactive LED displays and object tracking systems. It's a way for me to factories all those projects I was contracted for.


It's not a way to boost a signal.

It's using the Sun as a (gravity) lens, with probes at the focal point to gather the image. Because it's a very large lens, that's allow to have a massive zoom on whatever object we are interested in.


But you should be able to use it as a "parabolic" mirror, to make a very directed ray to the planet. (Assuming diffraction is not a problem.) (Assuming no time delay, because to see the planet you should look to were it was many years ago, but to send a message you should aim to where it will be many years in the future.) (Assuming I'm not missing a few more technical problems that are not impossible to solve, but extremely difficult.)


Wouldn't you have to have very accurate information about where the planet is going to be when the light arrives?


I had the same experience with computational geometry.

Very good at giving a textbook answer ("give a Python/ Numpy function that returns the Voronoi diagram of set of 2d points").

Now, I ask for the Laguerre diagram, a variation that is not mentioned in textbooks, but very useful in practice. I can spend a lot of time spoon-feeding the answer, I just have the bullshiting student answers.

I tried other problems like numerical approximation, physics simulation, same experience.

I don't get the hype. Maybe it's good at giving variations of glue code ie. Stack Overflow meet autocomplete ? As a search tool it's bad because it's so confidently incorrect, you may be fooled by bad answers.


Fixing the topological naming issue, in the mainline, what a game changer.

I am using Freecad for Actual Real Things. I learned to work around the topological naming issue, but it cost me time, and it can make parametric models quite brittle (ie. a minor change can break the model).


Was curious about the issue, found this: https://wiki.freecad.org/Topological_naming_problem


Yeah I am very much looking forward to that. Over the last 10 years I have made a couple of hundreds of designs in FreeCAD that I have manufactured in smal scale - with FDM/SLA/SLS 3d printing, CO2/fiber laser, and CNC milling in woods/plastics/metals. So it has been plenty productive. But quite often doing workarounds for the topological naming problem, either preemptively or corrective. Maybe I will start to teach it again to others :)


I rage quitted OpenSCAD for FreeCAD :p

For real, because I am way more productive with FreeCAD. FreeCAD allows to work in term of topological features like surfaces, edges, etc which is, in practice, very cumbersome with OpenSCAD.


Yet one flap is going to be eternal in human memory


One flap we know of, it is quite possible its counterpart suffered the same fate. No matter, the ship remained manoeuvrable and performed the landing flip even with half a flap - or half of two flaps - missing. That is valuable data which shows the thing can survive such damage without losing control. Now they'll need to find some way to better seal those hinge areas from the 20 minute plasma torch it is subjected to during re-entry.


Aptly dubbed Flap Norris.


That flap is already a legend, kept at it even mangled by hot plasma, crazy accelerations and pressures, spitting molten steel at the camera. What a role model, the little flap that could.


Someone on the Everyday Astronaut live stream named it "Flap Norris".


I wonder what the odds are that some deep sea salvage group is moving to collect that this very instant (or being contracted for such). If Starship lives up to even a fraction of its potential, that [not so] little guy is going to have some serious historicity.


They had a plane flying in the area shortly after landing, probably to drop some marker for a group to come around and recover the black box. I think they've stopped bothering with preserving the test articles though, in the process of test driven development, they're going to have so many "historic" test articles, that it's kind of pointless.


I'd be really surprised if they didn't have a GPS in the ship.

Which should mean they know where it "landed".


They still would've been in position to put down a marker, since they had to be prepared for that before they knew they'd be able to maintain telemetry down to the water, and if they're already in position, it doesn't hurt to place the marker anyway.


And the coordinates of where it "landed" are less important when it's drifting in the middle of the ocean.


According to ChatGPT, a Starship has 1000 cubic meters internal volume, and weighs 120 tons empty, which my manual math says is a density of 0.12, which means it should easily float in the ocean.


Not sure if I heard the commentary correctly, but I believe they said the video uplink was via starlink. If so, they should have the precise location.


The Russians and Chinese would probably love to examine those Raptors.


Not only the Russians and Chinese… Other countries and maybe some US companies too.


What makes you think it sank? If the hull is intact it might be floating. Given the flap damage, it's probably leaking though.


It looked like the booster exploded when it submerged after soft splashdown. There was some fire and the stream cut off. Maybe that's what happened to the ship too.


IIRC the intent was to sink it using explosives (Flight Termination System) in case it stays afloat after landing.


I think they had a tug go out to drag it to deeper water and make sure it sunk - there was some ship (ocean) commentry I saw in a couple of places showing the tracking data.


Absolutely genius! Go Chuck :)


And let's not forget about the other flap, toiling away away from publicity


Makes me want to play flappy bird.
