on 02026-10-05[Submitted on 8 Jul 2026 (v1), last revised 6 Sep 2026 (this version, v2)] “Recursive Self-Improvement in #AI: From Bounded Self-Refinement to Autonomous Research Loops”, by Mingguang Chen, Licheng Wang, Bo Qu. #paper. “We survey 1,250 arXiv papers (2024-2026) along two axes: what the system improves -- its behavior in deployment, its policy through training, its evaluator, or the research process itself -- and the degree of loop closure (human-in-the-loop to fully closed). The taxonomy separates bounded self-refinement -- convergent, evaluable, and industrial practice -- from open-ended recursive self-improvement (RSI), which remains bounded by grounding requirements, collapse dynamics, and compute constraints on every measured axis. Its distinctive feature is a dedicated category for self-evaluation: every improvement loop is a claim that some signal can substitute for human judgment.” 44 pages. #toread

on 02026-09-22#Video of Andrew Kelley's #lecture at #SXSW this year saying that (specifically for #AI) “if you don’t control the source code, you are not in control,” claiming AI agents are under the control of AI companies, which is of course true. There’s a section about disliking AI but using it anyway, and a section explaining how #Anubis is killing the open Web.
Very clear statement about the value of #free-software: “It primarily matters whether high-quality free software is available to users, providing competition that limits the degree to which proprietary software can get away with being coercive.” #toread

Law, finance, medicine, accounting, consulting, writing, design, analysis, customer service. Not in ten years. The people building these systems say one to five years. Some say less.

on 02026-02-24#CNBC #news #video #toread about "vanlords" renting RVs to people experiencing “RV homelessness” (aka #vanlife) in #California with RVs in RV parks such as wehope.org’s Berryessa Supportive Parking, whose program manager Victoria Garibaldi says they have 86 RVs.
“As the Bay Area’s housing shortage intensifies[,] vehicle-based homelessness has more than doubled since 2019, forcing even full-time workers into makeshift homes on wheels. This desperation has fueled a predatory shadow market where “vanlords” rent out aging RVs to those with no other options. While cities crack down on street encampments and ban these illegal rentals, San Jose is testing a different path with the Berryessa Safe Parking site, one of California’s largest sanctioned lots with space for 86 RVs. CNBC’s Kate Rogers visits the site to explore how these communities provide a vital bridge to long-term housing.” Says 37% of “homeless people” in Santa Clara County are now sleeping in vehicles, up from 18% in 02019.
Garibaldi says many of the vanlords charge only US$500 to US$600 per month for their RVs, which sounds amazingly cheap for the #SFBA. San Jose enacted a law against renting RVs on city streets last year; last year they opened a second “safe parking site”, bringing the total (?) to 128 RVs; Berryessa Supportive Parking provides breakfast, dinner, bathrooms, laundry facilities, a community garden, and a dog park. Meanwhile, for-profit RV parks like Candlestick RV Park, managed by Tsin Fung, charge US$2500 per month for a parking space.
In SF, Mayor Lurie limited RV parking on public streets to two hours with new legislation last July, with a so-called “Large Vehicle Refuge Permit” exemption permit available.

on 02026-01-14another #video #toread about aluminum-foil #batteries by #Thoisoi, who turns out to be Polish or Estonian, not Russian. He uses stainless-steel window screens as the cathode current collector, because it’s an #aluminum-air battery; in one case he adds a layer of graphite conductive spray paint to the screen. Additionally he’s going to use activated carbon for the cathode, sprinkling it on the epoxy-coated graphite-coated fine stainless-steel mesh, then pressing it in a jugaad five-tonne hydraulic press at 100° for 40 minutes, though he says you could just leave it for 12 hours at room temperature. In the end he has eight cathodes, four with a coarser mesh; the dry cathodes measure as only 8Ω or so on a non-autoranging multimeter. He’s making pouch cells with a food-bag hot sealer, which melts sheets of polyethylene (LDPE) together with a hot wire. His anode is 8-layer-thick aluminum foil. As an electrode separator, he uses a wet paper towel, and sandwiches the anode between two cathodes, I suppose to keep air from getting to it. Weirdly, he seals the pouch cell in plastic, so I’m not sure how the air is going to get to the cathodes. One of the cells uses 20mℓ o an electrolyte made from 5g NaCl and 5g NaHCO₃ #materials in 100mℓ of water, giving 0.75V which rapidly declines. On injecting 10mℓ 10% NaOH into the bag with a syringe, it perks up to 1.6V. Short-circuit current is 750mA, but he needs two in series (measuring 2.60V on the multimeters) to dimly light a red LED, suggesting an “internal resistance” of hundreds of ohms. With the NaOH he thinks its shelf life is only a few hours; his batteries were dead in four hours of playing his CD player.
I thought he was going to explain the results he got from different cathode geometries, but he never does. Also he never reports the power output of the battery or explains how the air is supposed to get in.

Abstract: We describe linear-time algorithms for solving a class of problems that involve transforming a cost function on a grid using spatial information. These problems can be viewed as a generalization of classical distance transforms of binary images, where the binary image is replaced by an arbitrary function on a grid. Alternatively they can be viewed in terms of the minimum convolution of two functions, which is an important operation in grayscale morphology. A consequence of our techniques is a simple and fast method for computing the Euclidean distance transform of a binary image. Our algorithms are also applicable to Viterbi decoding, belief propagation, and optimal control.

Apparently there’s a separable approach to this: “Like a Fourier Transform, you can apply it to 2D images by applying it horizontally on each row X, then vertically on each column Y (or vice versa).” ...really? Holy shit, you just count up with squared distances and everything works, that’s fucking insane. Then he figures out how to make it work with subpixel #antialiasing: “Here’s how I assembled a “true” Euclidean Subpixel Distance Transform.” #algorithms #toread

This paper highlights an important source of variation among college graduates: studying different academic fields has sizable effects on their political attitudes. Using surveys of about 300,000 students across 500 U.S. colleges, we find several results. First, relative to natural sciences, studying social sciences and humanities makes students more left-leaning, whereas studying economics and business makes them more right-leaning. Second, the rightward effects of economics and business are driven by positions on economic issues, whereas the leftward effects of humanities and social sciences are driven by cultural ones. Third, these effects extend to behavior: humanities and social sciences increase activism, while economics and business increase the emphasis on financial success. Fourth, the effects operate through academic content and teaching rather than socialization or earnings expectations. Finally, the implications are substantial.” #toread #politics

on 02025-12-08#video by Oskar Stalberg #toread on #dual-grid #tilesets for #videogames. For a triangle grid, you only need four little triangle “modules”! (If you can rotate them. He calls his tiles “modules” maybe because they have elevation.) For a square grid it’s 6. He demos a lot of stuff from his game "Townscaper", where the dual grid is entirely made of quads (somewhat skewed) but the primary grid (that the player interacts with) also has the occasional triangle, pentagon, or hexagon (corresponding to degree-3, degree-5, and degree-6 vertices in the primary grid). I wonder what other #tessellations might be interesting?
In another game, he’s doing a thing where he sort of goes back and forth between a triangular grid and a square grid, by cutting his square tiles into triangles in two different ways, and using #WaveFunctionCollapse with restarts to generate a terrain satisfying the implicit constraints of his modules. He’s generating islands from the edge with the constraint that each new module placed must be as high as or higher than the previously placed modules, thus avoiding the kinds of unrealistic local elevation minima that plague Minetest mapgen. This also helps to make the world navigable on foot.
He says he generates the Townscaper quad grid by subdividing a triangle grid, because you can subdivide a quad into four quads and you can subdivide a triangle into three quads, but then later he shows some stuff that sort of contradicts that, where before subdivision some of the triangles were joined up into quads.
Super interesting talk.

Apparently leaked lubricants were somehow forming phosphoric acid in the jet wash, which ate the concrete. Magnesium-phosphate pothole fillers were immune. Magnesium oxide (light, hard, or dead burned), ammonium or potassium phosphate salts, fly ash (40–60%) and boric acid to retard the reaction (though boric acid degrades the strength, by about 25% at 3% boric acid), and water. The set cement is struvite-K (MgKPO₄). He mentions that any unreacted phosphates are highly soluble, making porous concrete after they leach out.

Such intensifiers are used in X-ray imaging systems (such as fluoroscopes) to allow low-intensity X-rays to be converted to a conveniently bright visible light output. The device contains a low absorbency/scatter input window, typically aluminum, input fluorescent screen, photocathode, electron optics, output fluorescent screen and output window. These parts are all mounted in a high vacuum environment within glass or, more recently, metal/ceramic.”

Recommends a YT channel about bioplastics, @Giestas, a high-school teacher in Lisbon. Second recipe: 12 parts water, 3 parts cassava (or other) starch, 1 part vinegar, 1 part glycerin (as a plasticizer), optionally reinforced with cotton gauze. He claims you can separate potato starch by simple decantation. As usual, he butchers the science, claiming that freeze-dried starch gel is an aerogel. He claims that these starch gel films have high infrared emissivity, even though they look transparent to visible light. Third recipe, alginate — which, astoundingly, he mentions can be de-gelled by chelating the calcium with sodium citrate! And a suspension of calcium carbonate in sodium alginate can be gelled with vinegar, because that solubilizes the calcium! Or by using glucono-delta-lactone, tofu coagulant, to release acid over 10' to 20': 100mℓ water, 10g (sodium?) alginate, 2g CaCO₃, 2g GDL. Fourth recipe, agar, which dries into crystal-clear films that can resist water for a few days. 20g agar (!!) in only 100mℓ of hot water, 2mℓ dish detergent, whip with blender. #Giestas offers: “3 tbps agar, 2.5g citric acid, 3tbsp gli[cerin?], 1tsp baking soda” to produce foam; and “60mℓ agar, 30mℓ MGL [or “mel”: honey?], 60mℓ gli[cerin?], 180mℓ water, 5mℓ deter[gent?]”.

At 2'21" there’s a very alarming CERN slide, “The availability of magnetic materials has been declining over the years.
As of 2024 the assembly can be produced, but there is no replacement yet for the obsolete radial shield material (Nanophylm).” #collapse
The key here is that numbers of transformer windings “don’t have temperature coefficients or long-term drifts”, so they’re accurately ratiometric in a way that’s stable until and unless you bend the wire.
Guildline gave him the service manual, SM9930-H-00.
Internally it has an ovenized Weston cell in a test tube, which is used with a second light-beam galvanometer for feedback control of a 50mA current through a critical precision resistor, which is wire wound around a several-kilogram cylinder of brass; the soldered connections to the manganin (?) wires are stuck into a hole deep inside the brass to reduce possible thermal EMFs.
The nanovolt amplifier is a pair of antiparallel photocells powered by a lightbulb whose light is deflected by a third mirror galvanometer, this one 3.6kΩ.

this idea of "alloy agents" sounds interesting, alternating output tokens between different LLMs to avoid the weaknesses of each one. Scott Alexander says: “AI agents usually have long chains of thoughts/actions where each step depends on the step before. What happens if you alternate models at each step? That is, Step 1 is done by GPT, Step 2 is done by Claude, Step 3 is done by GPT again, etc, with each model thinking the entire previous chain of thoughts/actions is its own? A cybersecurity group claims the resulting “alloy” AI is more effective, since each model gets a chance to apply its strengths where others are weak.” #toread

The magnetic encoder uses “magnetic gearing” in the sense that it has 17 permanent magnets with alternating orientations moving past the IC in about a quarter turn, so you get about 68× higher precision (but no absolute readout).

Demonstrates “mode hops” on an oscilloscope; the initial heating using a temperature sensor (a transistor I think) is to get it to a mode-hop-free region, and then the current is PID-controlled to stabilize the wavelength, and a second control loop adjusts the temperature to “desaturate” the current controller. He says he got the wavelength stabilized to ±2nm “over a range of 200mm”, which I think means 10⁻⁸, not 2/555 or so. #optics #toread #hardware

on 02024-08-03#IMF Working #Paper No. 2024/085, on #Bitcoin cross-border flows. “The magnitudes of the estimated Bitcoin cross-border flows are sizeable with respect to several countries’ GDP, especially in those which experience relatively small capital flows. (...) Graf von Luckner et al. (...) find that Bitcoin has become an increasingly important channel to send remittances and evade capital controls in emerging markets [poor countries]. (...) LocalBitcoins flows are smaller in magnitude, reflecting that they capture transactions from a single exchange only. They can still be sizeable, however, for some countries with the upper quartile ranging from 0–1.7 percent of GDP on average over 2017–2022. It is worth noting that the distribution of Bitcoin cross-border flows is skewed to the right with the Seychelles registering the largest Chainalysis inflows of 2.5 percent of GDP followed by Venezuela with 0.8 percent of GDP and Moldova with 0.7 percent of GDP on average over 2019-2022. (...) As highlighted by IMF (2023a), policymakers aiming to manage capital flows should ensure that capital flow management regulations cover crypto assets. From a more structural perspective, it is certainly also important to address the [underlying] imbalances which manifest in exchange rate pressures, since the usage of crypto assets would represent just symptoms of the imbalances.” #toread

They’ve lived in it for four years; they parked near a public restroom. The faucet is powered by an electric pump; they toast breakfast with a butane torch. An inverter powers hair curlers. Gas stations provide trash disposal. Laundry is done in a laundromat once a week. Bathing is done in public baths. A steering-wheel-mounted desk holds a laptop at face height, using a wireless keyboard in the lap. A top-loading refrigerator is under part of the bed, which occupies all of the space behind the front seats. Elaborate cooking: panko-battered skewers of many kinds with okonomiyaki sauce, mixing up the batter in a plastic cup, fried in a pot on what looks like an induction stove.

on 02024-05-30#video #tutorial on #Godot multiplayer platformer based on the Brackeys platformer tutorial. ENetMultiplayerPeer and the Godot multiplayer API looks really easy to use in the case where it’s okay to depend on a server. I didn’t know Godot’s debug menu had a “run multiple instances” submenu, and in project settings, there's a Display→Window→Always on Top option, which is very useful for debugging. The MultiplayerSpawner node automatically replicates the scenes under its spawn path across all the players in the cluster, using its auto-spawn list to figure out how to instantiate them, except that it seems like actually you have to write code to manually instantiate scenes there? Maybe only on the server? By default only the server can change any (MultiplayerSynchronizer) node that’s synchronized across clients, but it can .set_multiplayer_authority(id) on a node to allow one of the players to change it instead.

on 02024-04-06Ryan Twomey #video on #vanlife #stealth-camping in airport parking lot #toread. He starts out camped at Lake Meredith in Texas. He was actually taking a round-trip flight from the airport (Albuquerque), though, so I don’t know if this really counts! Planet Fitness makes an appearance, the implication being that he showered there.
He has a black cloth curtain behind the driver seats. But I’m not sure how stealthy this setup actually is; it’s a gray huge-ish (Mercedes?) van that’s tall enough to stand up in, and a diesel heater, plus a fan in the ceiling to suck humid air out of the van, and there are solar panels clearly visible protruding off the sides of the van roof, and at night, when he has all the lights on inside, you can see the van’s back windows from inside, which makes me think they are probably visibly illuminated from outside.
He says the Albuquerque airport only charges US$7 a day (apparently for at-airport long-term parking of the camper van in the “Basic Economy lot,” which is in the sun), and he doesn’t have to worry about getting to the airport early. He actually prefers parking in the sun because it charges his battery through the rooftop solar panels and because he worries that otherwise his pipes might freeze.
Some of his kitchen stowage is in a hammock-like net hung from the bottom of the cabinets; another part is hexagonal jars screwed into lids attached to the bottom of the cabinets, over the sink. Lots of footage of cooking and eating.
He has some kind of internet connection in the van that’s about 90MB/s (500Mbps), maybe 4G, since no Starlink antenna panel is visible. He uses it to play Fortnite on a large monitor inside the van.
The whole ceiling has what looks like indirect LED lighting between some parallel wooden boards spaced some distance apart.
He takes his laundry to his friend’s house to wash it.
Commenters out that airports often feature bathrooms, free Wi-Fi, and a food court.

Mentions that square-loop ferrite (remanent flux/saturation flux ∈ [0.9, 0.95]) is usually MgMn ferrite (which I think is magnesium-manganese oxide). A one-core full-adder with five holes is shown on p.32 (the 38th of 70 pages); the next page has a three-hole “magnetic SPDT switch”. A “very short rise time” for a current pulse is glossed as “<0.1 μsec”. None of the references are in Russian or Ukrainian. #toread #history
on 02017-05-308-page open-access (thanks to the Computer History Museum!) IEEE #PDF #paper from 1959 on #magnetic-logic #hardware, “Square-Loop Magnetic Logic Circuits”, by Edward P. Stabler. Also mentions #ferroelectric capacitors, saying they are equivalent; this seems very promising for higher-frequency and smaller-dimension systems! Covers the physics from first principles, including the threshold, memory, and saturation properties of ferromagnetic materials (in general, not giving any actual numbers). Gives equivalent circuits, describes how to compose logic elements. “It is clear from the discussion that theoretically a single flux-steering gate can generate any combinational logic function.” Also describes how to use a network of simple toroidal cores to replicate all of the above. Unfortunately the scanned oscilloscope photographs are of quality too poor to read unambiguously. Includes a kind of “magnetic diode” that must be reset after use. #toread
