But we figure it’s safe enough to bend the rules a bit when the ones doing the protesting happen to be robots.About 30 bots gathered — or at least were commanded to gather by the event organizers — in Warsaw to spur discussion about the impact AI and robots will have on the labor market. Beyond getting public and media attention, the demonstration was also designed to raise awareness of what modern humanoid robots can do. While we appreciate the idea of showing robots taking the “jobs” of the protesters, it does seem somewhat ironic that marching around and chanting for hours is exactly the sort of repetitive work that most people would be happy to see taken over by machines.Although we hope these protests remain peaceful, there’s always a chance things can turn violent when tensions are high. Should things go south, take comfort in the knowledge that a company in Japan has introduced a robot ambulance service. It’s probably more accurate to compare it with roadside assistance, as the goal is to repair the robot on-site. That said, if the fault is more serious, they can bring the damaged bot back to HQ. Of course, the major difference between this program and a traditional ambulance service is that they’ll be able to bring along a spare robot that can take over the patient’s job while repairs are being made. Should anyone start doing that for humans, expect a few more protests.Would you need a subscription to fix this?Speaking of repairs, [Boone Ashworth] at WIRED recently wrote up an interesting hands-on experience he had with John Deere’s AI-driven DIY repair service at the company’s corporate headquarters. Armed with a laptop and tasked with fixing the error message showing on a ~$120,000 USD tractor, he was able to follow the instructions provided by the software to identify a sensor that had been unplugged. Reconnecting the sensor fixed the error message and elicited applause from the Deere reps who presumably had carefully unplugged the sensor in the first place for the purposes of the demonstration.If that doesn’t strike you as a particularly impressive display for a subscription service which starts at $195 a year for each individual machine, you aren’t alone. When Boone reported his experience to critics of Deere’s repairability track record, it was met with literal laughter. You don’t have to have worked in the fields to know that a sensor becoming unplugged ranks pretty low on the list of potential problems you might face in the middle of a harvest.We can certainly understand why Deere wouldn’t ask journalists to fix a blown clutch or a leaky hydraulic cylinder for the purposes of a media demo. Even so, they could surely have come up with something a bit more challenging if their goal was to convince customers to log into their repair service — something the company claims only about a thousand users do each day.Finally, this one leans more heavily into the “arts and crafts” than we’d usually cover here on Hackaday, but [Terence Eden]’s Collection of Imaginary Software is too cool not to get a mention.The idea is simple enough: make up fake disk labels for a bunch of fictional pieces of software (think the games David Lightman was trying to get his hands on in WarGames), stick them on some of the old 3.5 floppies we know you have hiding in a box somewhere, and put them in a frame.As we’ve talked about in the past, many of us in the hacker and maker community were inspired by nerds in the media. This project strikes us as a fantastic way to show off just which examples you resonated with personally, and if any readers come up with something similar to adorn the walls of their basement, we’d love to see it.See something interesting that you think would be a good fit for our weekly Links column?

You have an Egret GT E-scooter. It has a screen that shows the usual dash stats, but that led to an annoyance. You could accidentally enter firmware update mode and, from there, enter operational mode without the security PIN. [Ben] couldn’t let that stand, so he reverse-engineered the protocol and rewrote the firmware in Rust. As he put it, “… because I have to break… everything I own…” We get it.The mobile app was useful for some basic info, since sniffing Bluetooth is fairly easy and analyzing mobile code is, more or less, straightforward. Analysis revealed some data that doesn’t show on the display and that several things are sent back to home base tagged with the scooter’s unique ID — another reason to gut the existing firmware.Internally, the scooter uses the CAN Bus, so out came the oscilloscope and a homebrew CAN decoder.  Surprisingly, the CAN bus is accessible on the USB-C port’s data pins. Officially, the port is only for charging phones, so you have to wonder what your phone makes of the alien signals on the data pins when it is charging.Firmware updates actually come in at least three flavors: display, input panel, and main controller. Reverse engineering the firmware update process was crucial to installing the new firmware.If you own a similar scooter, this post is a goldmine. If you don’t, it is still a very detailed breakdown of a reverse-engineering workflow, and you can apply many of the tools and techniques to your next project.Of course, another option is to just keep the scooter and replace the brains. If you want to learn more about reverse engineering, there are literally dozens of Hackaday posts to help you get started.hackaday.com/2026/09/13/rustin…]]></description><link>https://forum.pierobosio.it/topic/2f70f0e6-0cfd-45df-abcc-6e4bad0400e7/rusting-an-e-scooter-in-a-good-way</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/2f70f0e6-0cfd-45df-abcc-6e4bad0400e7/rusting-an-e-scooter-in-a-good-way</guid><dc:creator><![CDATA[cybersecurity@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 20:00:03 GMT</pubDate></item><item><title><![CDATA[Una mia amica ha condiviso questa cosa su WhatsApp.]]></title><description><![CDATA[Una mia amica ha condiviso questa cosa su WhatsApp. L'ha trovata sicuramente su Facebook.Stavo pensando... ma quanto si riesce a guadagnare facendo il "content creator" con puttanate del genere?Perché io sinceramente un pensierino ce lo farei...]]></description><link>https://forum.pierobosio.it/topic/4b2b224f-7fde-4b04-9942-e4e475f788ad/una-mia-amica-ha-condiviso-questa-cosa-su-whatsapp.</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/4b2b224f-7fde-4b04-9942-e4e475f788ad/una-mia-amica-ha-condiviso-questa-cosa-su-whatsapp.</guid><dc:creator><![CDATA[max@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 18:18:29 GMT</pubDate></item><item><title><![CDATA[A 386 PC For Your RP2350]]></title><description><![CDATA[A 386 PC For Your RP2350We’re at a fortunate moment: microcontrollers available at modest prices are edging into the capability level previously reserved for full-fat systems and can, through emulation, run software beyond classic 8-bit home computers, consoles, or old arcade games. A project we’ve been watching for a while is tiny386, an emulator for ESP32 boards that provides a 386 PC with just enough 486 and 586 instructions enabled to run a modern Linux kernel. Now we’re pleased to note that this platform is making it to the RP2350, with ports for both the FRANK emulation platform and the Waveshare Pi Zero boards. You can now have a 32-bit PC with all the peripherals, including VGA and DVI/HDMI, for the cost of an inexpensive development board.Having seen tiny386 run on its minimum-spec ESP32 platform, we’ll concede that while it’s usable, it’s not the fastest experience, but the RP2350 port promises better performance. It’s not for a modern full-fat Linux distro, but should work well for running older operating systems such as DOS, or Windows 3.1 and 95, or even a lean Linux setup. This has fascinating potential: while these systems are old, they still have an enormous software library. The idea of useful general-purpose computing, 1990s style, in the palm of the hand, is interesting.If you’re curious, you can find tiny386 here and the FRANK boards here.

One of these, the FSCALE instruction turned out to be far more complicated than assumed, with one might assume to be a straightforward powers-of-two scaling turning out to entail over 140 micro-instructions and three levels of sub-routine calls just to handle all cases.The annotated die shot in the heading image shows the functional blocks that are used by this one x87 instruction, to give some kind of idea of what amount of hardware even ‘just’ scaling a floating point number involves.Much like with the x86’s CISC-style ISA, these 8087 instructions break down into individual steps that involve everything from loading values into registers, performing operations, checking for and handling error conditions as well as stack management. As can be seen in [Ken]’s breakdown of the FSCALE implementation in the 8087 it’s all very logical, taking a high-level instruction and doing all that’s needed for a robust implementation, without bothering the developer with the details.Of note is that the 8087’s implementations led to the IEEE 754 floating point standard, providing what definitely at the time was one of the most mathematically accurate FPUs that somehow still was financially responsible enough to make it into a relatively affordable PC.hackaday.com/2026/09/13/analyz…]]></description><link>https://forum.pierobosio.it/topic/8d9d22ee-6fb5-480d-9975-8e8f3e35303e/analyzing-the-fscale-instruction-in-intel-s-8087-fpu</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/8d9d22ee-6fb5-480d-9975-8e8f3e35303e/analyzing-the-fscale-instruction-in-intel-s-8087-fpu</guid><dc:creator><![CDATA[cybersecurity@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 14:00:33 GMT</pubDate></item><item><title><![CDATA[Un vecchio Pixel 7 diventa un mini computer per l’IA offline: il 3B gira in locale senza cloud]]></title><description><![CDATA[Anche uno smartphone di quattro anni fa può ritagliarsi un ruolo nell’era dell’intelligenza artificiale, a patto di reinventarne l’uso. Un utente ha trasformato un Google Pixel 7 in un piccolo computer portatile capace di eseguire un modello di IA da 3 miliardi di parametri interamente in locale, senza bisogno di connessione a internet né di appoggiarsi a servizi cloud.Un cyberdeck fai da te costruito attorno al Pixel 7Il progetto, ribattezzato “cyberdeck” dal suo creatore, consiste in una scocca personalizzata stampata in 3D che racchiude il Pixel 7 trasformandolo in un dispositivo dall’aspetto di un piccolo computer portatile. Per progettare la struttura è stato utilizzato Claude Code, lo strumento a riga di comando basato su intelligenza artificiale, mentre nella parte inferiore del case trova posto una batteria esterna che estende l’autonomia rispetto al solo smartphone.Sullo schermo del dispositivo viene mostrato un terminale in stile Linux, dal quale è possibile richiamare direttamente gli strumenti da riga di comando di Claude Code, rendendo l’esperienza d’uso molto simile a quella di un vero e proprio computer portatile compatto.Qwen2.5 da 3 miliardi di parametri, tutto sul dispositivoIl modello scelto per l’esperimento è Qwen2.5-abliterate:3b, una versione da 3 miliardi di parametri privata dei filtri di sicurezza originali. Il punto centrale del progetto è che l’intero processo di inferenza avviene sul dispositivo: nessun dato viene inviato a server esterni e il modello può essere utilizzato anche in totale assenza di connettività, una caratteristica che lo rende interessante per chi vuole sperimentare con l’IA locale mantenendo il pieno controllo sulla privacy dei propri dati.I limiti dell’hardware: circa 5 token al secondoVa detto che le prestazioni non sono all’altezza di un modello recente: il Tensor G2 e gli 8 GB di RAM del Pixel 7 permettono di generare testo a una velocità di circa 5 token al secondo, un ritmo tutt’altro che elevato che si traduce in tempi di attesa piuttosto lunghi quando si richiedono risposte più articolate. Un limite prevedibile, considerando che si tratta di un chip pensato principalmente per la fotografia computazionale e non per carichi di lavoro di questo tipo.Dispositivo: Google Pixel 7 con chip Tensor G2 e 8 GB di RAMModello IA: Qwen2.5-abliterate:3b, 3 miliardi di parametriVelocità di generazione: circa 5 token al secondoElaborazione interamente offline, senza invio di dati al cloudCase stampato in 3D progettato con l’aiuto di Claude CodeUna seconda vita per gli smartphone Android più datatiAl di là della velocità limitata, l’esperimento dimostra che uno smartphone Android di alcuni anni fa può ancora avere un impiego pratico: quello di terminale dedicato per l’IA locale. Poter eseguire un modello linguistico senza connessione e senza condividere dati con servizi esterni è un vantaggio non da poco per chi ha a cuore la privacy, e apre la strada a un possibile riutilizzo dei tanti Pixel e telefoni Android che finiscono dimenticati in un cassetto. Con modelli sempre più leggeri e ottimizzati, iniziative come questa potrebbero diventare sempre più comuni tra gli appassionati.]]></description><link>https://forum.pierobosio.it/topic/631ecbf1-093c-4670-974a-93e320767b8f/un-vecchio-pixel-7-diventa-un-mini-computer-per-l-ia-offline-il-3b-gira-in-locale-senza-cloud</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/631ecbf1-093c-4670-974a-93e320767b8f/un-vecchio-pixel-7-diventa-un-mini-computer-per-l-ia-offline-il-3b-gira-in-locale-senza-cloud</guid><dc:creator><![CDATA[blog@androidiani.net]]></dc:creator><pubDate>Sun, 13 Sep 2026 12:12:02 GMT</pubDate></item><item><title><![CDATA[Triaged a large batch of issues found by a zkao.io scan.]]></title><description><![CDATA[Triaged a large batch of issues found by a zkao.io scan.

[ekaggrat singh kalsi]’s OVODYO is a particularly intriguing approach, tumbling a pair of icosahedral counters to display the current time.Each 3D-printed icosahedron has numerals sunk through each of its twelve sides, and is raised above the base of the clock on a brass support shaft. An inner drive shaft runs through the center of the support shaft and drives a set of beveled gears. These spin the outer shells around two axes, periodically cycling through all twelve faces. The pattern in which an icosahedron rotates means that only set of numerals appears upright at a time, making it easier to distinguish the time.A split path around the icosahedra both lets them rotate around the support shaft and shows off the internal gearing. On the control side, an ATmega8 drives a pair of stepper motors with drv8833 motor drivers, using a hall effect sensor to detect each indicator’s position. Since the minutes dial only gives the time in five-minute intervals, it also drives an LED strip to indicate the exact minute.[ekaggrat] has a long history of creative clock designs, from this dynamic chain-link sculpture to a hair-tie clock or a mechanical seven-segment display.youtube.com/embed/2dgew57z5dg?…hackaday.com/2026/09/13/keepin…]]></description><link>https://forum.pierobosio.it/topic/9ae1b119-a26d-48f7-bb99-75dc3f4062f1/keeping-time-on-tumbling-icosahedra</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/9ae1b119-a26d-48f7-bb99-75dc3f4062f1/keeping-time-on-tumbling-icosahedra</guid><dc:creator><![CDATA[cybersecurity@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 11:00:46 GMT</pubDate></item><item><title><![CDATA[I know you were all waiting for this so here is my Sunday breakfast setting.]]></title><description><![CDATA[I know you were all waiting for this so here is my Sunday breakfast setting.Assam tea, some toasted bred with "olives paté" from Liguria and a bit of Dharma.(I had to rewrite this post from scratch because I forgot to add the picture)]]></description><link>https://forum.pierobosio.it/topic/f3a022c1-681a-43ec-a47d-8619f97a52fb/i-know-you-were-all-waiting-for-this-so-here-is-my-sunday-breakfast-setting.</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/f3a022c1-681a-43ec-a47d-8619f97a52fb/i-know-you-were-all-waiting-for-this-so-here-is-my-sunday-breakfast-setting.</guid><dc:creator><![CDATA[max@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 09:02:41 GMT</pubDate></item><item><title><![CDATA[LA CAMERA CINESE, OVVERO PERCHÉ L’INTELLIGENZA ARTIFICIALE NON È INTELLIGENTE, MA PERICOLOSA]]></title><description><![CDATA[@filobus non sarebbe affatto strano 🤭]]></description><link>https://forum.pierobosio.it/topic/94da9038-1b18-4d42-ad2a-a3e568accfbe/la-camera-cinese-ovvero-perché-l-intelligenza-artificiale-non-è-intelligente-ma-pericolosa</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/94da9038-1b18-4d42-ad2a-a3e568accfbe/la-camera-cinese-ovvero-perché-l-intelligenza-artificiale-non-è-intelligente-ma-pericolosa</guid><dc:creator><![CDATA[informapirata@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 08:41:21 GMT</pubDate></item><item><title><![CDATA[@Tarnport]]></title><description><![CDATA[@TarnportI made a mistake, I wrote "studio" but I meant "study" as you wrote in your post, sorry for that.And yes, you're right, in Italian "studio" is a noun with two meanings.1.

Reliably getting a crack out of a whip takes skill and practice, though, which is why [Craig Turner] built a whip-cracking machine.The first step was to build the whip itself, which was surprisingly complicated. Bullwhips taper down toward the end of the whip. As the whip uncurls during a crack, momentum passes down the whip; since the whip becomes continually narrower and lighter, conservation of momentum means that different stretches of the whip must move progressively faster. To get this effect, [Craig] joined together a series of increasingly thin and light ropes. The heavy end of the whip terminated in an eyelet connected to a length of elastic shock cord. Stretching the whip back on the shock cord and releasing it whipped it around, resulting in a fairly reliable crack.For greater convenience, [Craig] built this into a launcher mechanism, with the elastic cord wrapped around the end of the launcher, an electrical-conduit guide for the whip, and a spring-loaded trigger mechanism to release it. This worked even better than expected, getting a reliable crack every time. The tip of the whip could slice leaves, tear open aluminium cans, put out candle flames, knock the cap off a bottle without tipping it over, and reliably hit small targets on the first shot.As [Craig] mentioned, this setup would make it much easier to study the cracking effect with a schlieren imaging setup.youtube.com/embed/-IzLniCbFvk?…hackaday.com/2026/09/13/whip-c…]]></description><link>https://forum.pierobosio.it/topic/d5d3c4b5-ad2d-4895-b570-1d5ad4e4c72d/whip-cracking-machine-reliably-breaks-the-sound-barrier</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/d5d3c4b5-ad2d-4895-b570-1d5ad4e4c72d/whip-cracking-machine-reliably-breaks-the-sound-barrier</guid><dc:creator><![CDATA[cybersecurity@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 08:00:15 GMT</pubDate></item><item><title><![CDATA[Il fragile patto di fiducia della cybersecurity]]></title><description><![CDATA[Il fragile patto di fiducia della cybersecurity@informaticaTra regole non scritte, patti traditi e vendette, il caso Nightmare Eclipse mostra quanto sia delicato il sistema che regola la divulgazione delle vulnerabilità informatiche.#GuerreDiRete è la newsletter fondata da Carola Fredianiguerredirete.substack.com/p/il…]]></description><link>https://forum.pierobosio.it/topic/8856da71-75c5-4543-acd4-827c0e4fa471/il-fragile-patto-di-fiducia-della-cybersecurity</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/8856da71-75c5-4543-acd4-827c0e4fa471/il-fragile-patto-di-fiducia-della-cybersecurity</guid><dc:creator><![CDATA[cybersecurity@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 07:54:16 GMT</pubDate></item><item><title><![CDATA[#silentsunday #love #books #food #leisure]]></title><description><![CDATA[@altlifeThanks.In half an hour I'll share my breakfast and Sunday book.Be ready 😁]]></description><link>https://forum.pierobosio.it/topic/ee91531a-ddcb-4053-be3a-82e057368bdc/silentsunday-love-books-food-leisure</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/ee91531a-ddcb-4053-be3a-82e057368bdc/silentsunday-love-books-food-leisure</guid><dc:creator><![CDATA[max@poliverso.org]]></dc:creator><pubDate>Sun, 13 Sep 2026 07:22:12 GMT</pubDate></item><item><title><![CDATA[☕ CYBERBRIEFING — Domenica 13 settembre 2026]]></title><description><![CDATA[☕ CYBERBRIEFING — Domenica 13 settembre 2026 👉 Leggi tutti gli aggiornamenti delle ultime 24 ore: https://ilpuntocyber.rfeed.it/article.php?s=2026-09-13#newsletter #cybersecurity@informatica]]></description><link>https://forum.pierobosio.it/topic/ce519848-502d-4dec-ba22-b676bc3e2286/cyberbriefing-domenica-13-settembre-2026</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/ce519848-502d-4dec-ba22-b676bc3e2286/cyberbriefing-domenica-13-settembre-2026</guid><dc:creator><![CDATA[nuke@poliversity.it]]></dc:creator><pubDate>Sun, 13 Sep 2026 06:46:26 GMT</pubDate></item><item><title><![CDATA[@troberts I think I've only played StarCraft a handful of times, and it was centuries ago]]></title><description><![CDATA[@troberts I think I've only played StarCraft a handful of times, and it was centuries agoI don't remember what the units saidbut I definitely read those phrases in that tone, and now they are playing in my mind:D]]></description><link>https://forum.pierobosio.it/topic/7269a9f1-dfa0-4a5f-ad47-56d3b4521798/@troberts-i-think-i-ve-only-played-starcraft-a-handful-of-times-and-it-was-centuries-ago</link><guid isPermaLink="true">https://forum.pierobosio.it/topic/7269a9f1-dfa0-4a5f-ad47-56d3b4521798/@troberts-i-think-i-ve-only-played-starcraft-a-handful-of-times-and-it-was-centuries-ago</guid><dc:creator><![CDATA[valhalla@social.gl-como.it]]></dc:creator><pubDate>Sun, 13 Sep 2026 06:42:39 GMT</pubDate></item></channel></rss>
