“Sorry, my mic was muted…” With the rise of video calls, we’ve all found ourselves rushing to mute or unmute our mics in the midst of a call. This open-source Mute Button, sent in by [blackdevice], aims to take out the uncertainty and make toggling your mic easy.
It’s centered around a small PIC32MM microcontroller that handles the USB communications, controls the three built-in RGB LEDs, and reads the inputs from the encoder mounted to the center of this small device. The button knob combo is small enough to easily move around your desk, yet large enough to toggle without fuss when it’s your turn to talk.
To utilize all the functions of the button, you’ll need to install the Python-based driver on your machine. Doing so will let you not only toggle your microphone and volume, but it will also allow the button to light up to get your attention should you be trying to talk with the mic muted.
Although small, it’s also quite rugged, knowing it will spend its life being treated much like a game of Whac-A-Mole—slapped whenever needed. The case is designed to be 3D printed by any FDM printer, with the top knob section printed in translucent material to make the notification light clearly visible.
All of the design files, firmware, and parts list are available over on [blackdevices]’s GitHub page, and they are open-source, allowing you to tweak the design to fit your unique needs. Thank you for sending in this well-documented project, [blackdevices]; we look forward to seeing future work.

@Informatica (Italy e non Italy 😁) WhatsApp ha confermato di aver corretto una vulnerabilità critica nelle sue applicazioni per iOS e macOS, sfruttata in attacchi mirati negli ultimi mesi. Si tratta di uno scenario da manuale di cyber-spionaggio: un
E’ stata rilevata una falla critica zero-day nei sistemi Citrix NetScaler, catalogata come CVE-2025-6543, che è stata oggetto di sfruttamento attivo da parte degli hacker criminali da maggio 2025, parecchi mesi prima della messa a disposizione di una soluzione correttiva. Inizialmente Citrix aveva parlato di una semplice vulnerabilità di overflow di memoria in grado di causare un flusso di controllo anomalo e un Denial of Service, ma in seguito è emerso che la breccia di sicurezza in realtà permette l’esecuzione di codice remoto (RCE) senza necessità di autenticazione, con il risultato di una potenziale vasta compromissione di sistemi a livello mondiale.
Il bug monitorato come CVE-2025-6543 consente a un aggressore di sovrascrivere la memoria di sistema fornendo un certificato client dannoso all’endpoint /cgi/api/loginsu un dispositivo NetScaler vulnerabile. Inviando centinaia di queste richieste, un aggressore può sovrascrivere una quantità di memoria sufficiente per eseguire codice arbitrario sul sistema. Questo metodo gli fornisce un punto d’appoggio nella rete, che ha utilizzato per spostarsi lateralmente negli ambienti Active Directory , abusando delle credenziali rubate dell’account del servizio LDAP.
La società ha messo a disposizione uno script di verifica per rilevare le compromissioni, ma soltanto su richiesta specifica e in circostanze molto ristrette, senza tuttavia offrire una spiegazione approfondita circa la situazione o le limitazioni dello script stesso. Le prove suggeriscono che Citrix era a conoscenza della gravità e dello sfruttamento in corso, ma non ha rivelato la reale portata della minaccia ai propri clienti, ha affermato Kevin Beaumont .
Le organizzazioni che hanno dispositivi Citrix NetScaler collegati a Internet sono invitate dagli esperti di sicurezza a prendere immediati provvedimenti. Se si ritiene che un sistema sia compromesso, i passaggi consigliati sono:
Disattivare immediatamente il dispositivo NetScaler.
Creare un’immagine del sistema per l’analisi forense.
Modificare le credenziali dell’account del servizio LDAP per impedire spostamenti laterali.
Distribuisci una nuova istanza di NetScaler con patch e credenziali aggiornate.
Il Centro Nazionale Olandese per la Sicurezza Informatica (NCSC) ha svolto un ruolo fondamentale nello svelare la vera natura degli attacchi. La sua indagine ha confermato che la vulnerabilità è stata sfruttata come vulnerabilità zero-day e che gli aggressori hanno attivamente coperto le proprie tracce, rendendo difficile l’analisi forense. Il rapporto, pubblicato nell’agosto 2025, affermava che “diverse organizzazioni critiche nei Paesi Bassi sono state attaccate con successo” e che la vulnerabilità è stata sfruttata almeno dall’inizio di maggio.
A Giugno 2025 si è concluso il rilascio da parte di Citrix di una patch riguardante la CVE-2025-6543. Gli aggressori, tuttavia, avevano sfruttato la falla di sicurezza già da diverse settimane. La vulnerabilità è stata sfruttata per violare i sistemi di accesso remoto NetScaler, diffondere webshell in grado di assicurare un accesso persistente anche dopo l’applicazione delle patch, e portare via le credenziali.
Si ritiene che lo stesso sofisticato autore di minacce sia dietro lo sfruttamento di un altro zero-day, CVE-2025-5777, noto anche come CitrixBleed 2, utilizzato per rubare le sessioni utente. Sono in corso specifiche indagini per stabilire se questo attore sia responsabile anche dello sfruttamento di una vulnerabilità più recente, CVE-2025-7775.

Convenient though they may be, [Trevor Faber] found some serious shortcomings in shifting spanners: their worm gears are slow to adjust and prone to jamming, they don’t apply even force to all faces of a bolt head, and without a ratchet, they’re rather slow. To overcome these limitations, he designed his own adjustable ratchet wrench.
The adjustment mechanism is based on a pair of plates with opposing slots; the wrench faces are mounted on pins which fit into these slots, and one plate rotates relative to the other, the faces slide inwards or outwards. A significant advantage of this design is that, since one plate is attached to the wrench’s handle, some of the torque applied to the wrench tightens its grip on the bolt. To let the wrench loosen as well as tighten bolts, [Trevor] simply mirrored the mechanism on the other side of the wrench. Manufacturing proved to be quite a challenge: laser cutting wasn’t precise enough for critical parts, and CNC control interpolation resulted in some rough curves which caused the mechanism to bind, but after numerous iterations, [Trevor] finally got a working tool.
To use the wrench, you twist an outer ring to open the jaws, place them over the bolt, then let them snap shut. One nice touch is that you can close this wrench over a bolt, let go of it, and do something else without the wrench falling off the bolt. Recessed bolts were a bit of an issue, but a chamfer ought to improve this. It probably won’t be replacing your socket set, but it looks like it could make the odd job more enjoyable.
If you prefer a more conventional shifting wrench, you can make a miniature out of an M20 nut. It’s also possible to make a shifting Allen wrench.
Il Pentagono ha inviato una “lettera di preoccupazione” a Microsoft documentando una “violazione di fiducia” in merito all’utilizzo da parte dell’azienda di ingegneri cinesi per la manutenzione di sistemi informatici governativi sensibili, ha annunciato questa settimana il Segretario alla Difesa Pete Hegseth.
Allo stesso tempo, il Dipartimento della Difesa sta avviando un’indagine per verificare se qualcuno di questi dipendenti abbia compromesso la sicurezza nazionale.
“L’impiego di cittadini cinesi per la manutenzione degli ambienti cloud del Dipartimento della Difesa è finito”, ha affermato Hegseth in una dichiarazione video. “Abbiamo inviato una lettera formale di preoccupazione a Microsoft documentando questa violazione della fiducia e stiamo richiedendo un audit di terze parti sul programma di scorta digitale di Microsoft, incluso il codice e le richieste dei cittadini cinesi”.
“Hanno inserito qualcosa nel codice di cui non eravamo a conoscenza? Lo scopriremo”, ha aggiunto Hegseth.
Le azioni sono state intraprese in risposta a una recente indagine che ha svelato il sistema di “scorta digitale” di Microsoft, in cui personale statunitense con autorizzazioni di sicurezza supervisiona ingegneri stranieri, compresi quelli in Cina. ProPublica ha scoperto che gli addetti alla scorta spesso non possiedono le competenze necessarie per supervisionare efficacemente ingegneri con competenze tecniche molto più avanzate.
Il colosso della tecnologia ha sviluppato questo accordo per aggirare il requisito del Dipartimento della Difesa secondo cui le persone che gestiscono dati sensibili devono essere cittadini statunitensi o residenti permanenti.
“Il programma è stato progettato per rispettare le norme sugli appalti, ma ha esposto il dipartimento a rischi inaccettabili”, ha affermato Hegseth in un annuncio video pubblicato su X. La lettera serve da avvertimento a Microsoft, che ha dichiarato nei suoi report finanziari di ricevere “ingenti entrate da contratti governativi”. È meno grave di una “cura notice”, che potrebbe portare alla risoluzione dei contratti Microsoft se i problemi non vengono risolti.
Il dipartimento non ha reso pubblica la lettera e non ha risposto alla richiesta di ProPublica di averne una copia
This Stunning Image of the Sun Could Unlock Mysterious Physics
Welcome back to the Abstract! What an extreme week it has been in science. We’ve got extreme adaptations and observations to spare today, so get ready for a visually spectacular tour of deep seas, deep time, and deep space.
First up, a study with an instant dopamine hit of a title: “Extreme armour in the world’s oldest ankylosaur.” Then, stories about two very different marine creatures that nonetheless share a penchant for brilliant outfits and toxic lifestyles; a baby picture that requires a 430-light-year zoom-in; and lastly, we must once again salute the Sun in all its roiling glory. Enjoy the peer-reviewed eye-candy!
Paleontologists have discovered an ankylosaur that is epic even by the high standards set by this family of giant walking tanks. Partial remains of Spicomellus—the oldest known ankylosaur, dating back 165 million years—reveal that the dinosaur had much more elaborate body armor than later generations, including a collar of bony spikes up to three feet long, and fused tail vertebrae indicating an early tail weapon.
The team doesn’t hide their amazement at the find, writing that “no known ankylosaur possesses any condition close to the extremely long pairs of spines on the cervical half-ring” and note that the fossils overturn “current understanding of tail club evolution in ankylosaurs, as these structures were previously thought to have evolved only in the Early Cretaceous.”
This incredible armor may have initially evolved as a sexual display that was adapted for defensive purposes by the rise of “multitonne predators” like T. rex. That might explain why the ornaments seemed to have simplified over time. Whatever the reason, the fossils demonstrate that ankylosaurs, as a lineage, were born ready for a fight.
We’ll move now from the extremely epic to the extremely twee. Pygmy seahorses, which measure no more than an inch, mimic the brightly-colored and venomous gorgonian corals that they symbiotically inhabit. Scientists have now discovered that these tiny animals achieved their extraordinary camouflage in part by discarding a host of genes involved in growth and immune response, perhaps because their protective coral habitats rendered those traits obsolete. Basically we are very smol. Image: South China Sea Institute of Oceanology, Chinese Academy of Sciences “We analyzed the tiny seahorse’s genome revealing the genomic bases of several adaptations to their mutualistic life,” said researchers led by Meng Qu of the South China Sea Institute of Oceanology, Chinese Academy of Sciences. The analysis suggests “that the protective function of corals may have permitted the pygmy seahorse to lose an exceptionally large number of immune genes.”
Living in a toxic environment can have its benefits, if you’re a seahorse. And that is the perfect segue to the next story…
When life hands you arsenic, make lemon-colored skin
After a long day, isn’t it nice to sink into a scalding bath of arsenic and hydrogen sulfide? That’s the self-care routine for Paralvinella hessleri, a deep sea worm that “is the only animal that colonizes the hottest part of deep-sea hydrothermal vents in the west pacific,” according to a new study. Paralvinella hessleri. Wang H, et al., 2025, PLOS Biology, CC-BY 4.0 (creativecommons.org/licenses/b…) So, how are these weirdos surviving what should be lethally toxic waters that exceed temperatures of 120°F? The answer is a "distinctive strategy” of “fighting poison with poison,” said researchers led by Hao Wang of the Center of Deep-Sea Research, Chinese Academy of Sciences. The worm stores the arsenic in its skin cells and mixes it with the sulfide to make a dazzling mineral, called orpiment, that provides its bright yellow hue.
“This process represents a remarkable adaptation to extreme chemical environments,” the researchers said. “The yellow granules observed within P. hessleri’s epithelial cells, which are the site of arsenic detoxification, appear to be the key to this adaptation.”
My own hypothesis is that this worm offers an example of convergent evolution with Freddie Mercury’s yellow jacket from Queen’s legendary 1986 Wembley Stadium performance.
Your baby photos are cute and all, but it’s going to be hard to top the pic that astronomers just snapped of a newborn planet 430 light years from Earth. This image marks the first time that a planet has been spotted forming within a protoplanetary disk, which is the dusty gassy material from which new worlds are born. The protoplanet WISPIT 2b appears as a purple dot in a dust-free gap. Image: Laird Close, University of Arizona Our “images of 2025 April 13 and April 16 discovered an accreting protoplanet,” said researchers led by Laird Close of the University of Arizona. “The ‘protoplanet’ called WISPIT 2b “appears to be clearing a dust-free gap between the two bright rings of dust—as long predicted by theory.”
If Earth is the pale blue dot, then WISPIT 2b is the funky purple blob. Though stray baby planets have been imaged before in the cavity between their host stars and the young disks, this amazing image offers the first glimpse of the most common mode of planetary formation, which occurs inside the dusty maelstrom.
We’ll close with yet another cosmic photoshoot—this time of everyone’s favorite star, the Sun. from the Daniel K Inouye Solar Telescope (DKIST) in Hawaii. The telescope captured unprecedented pictures of a decaying solar flare at a key hydrogen-alpha (Hα) wavelength of 656.28 nanometers.
The images show coronal loops—dramatic plasma arches that can spark flares and ejections—at resolutions of just 13 miles, making them the smallest loops that have ever been observationally resolved. The pictures are mesmerizing, filled with sharp features like the “Arcade of Coronal Loops” (and note that the scale is measured in planet Earths) But they also represent a new phase in unlocking the mysterious physics that fuels solar flares and coronal mass ejections.
“This is initial evidence that the DKIST may be capable of resolving the fundamental scale of coronal loops,” said researchers led by Cole Tamburri of the University of Colorado Boulder. “The resolving power of the DKIST represents a significant step toward advancing modern flare models and our understanding of fine structure in the coronal magnetic field.”
May your weekend be as energetic as a coronal loop, but hopefully not as destructive.

Al meeting di Comunione e Liberazione abbiamo avuto la prova certa che questa associazione è un'attività politica che nulla ha in comune con la religione cristiana. Lo dimostrano gli applausi scroscianti alla Presidente del Consiglio che lamentava che Israele avesse superato il livello atteso di proporzionalità nell'uccidere i palestinesi a Gaza come ritorsione dei fatti del 7 ottobre. Per CL se Israele avesse adottato il criterio nazi-fascista di 10 civili palestinesi contro 1 israeliano sarebbe stato giusto e cristianamente accettabile? La Presidente del Consiglio che con queste affermazioni ha dimostrato ancora una volta che i profondi legami con le ideologie nazi-fasciste non l'hanno abbandonata, ma un'associazione che si dichiara cristiane e cattolica (?) e applaude a certe affermazioni è una contraddizione al messaggio evangelico e una chiara evidenza di eresia.
This is Behind the Blog, where we share our behind-the-scenes thoughts about how a few of our top stories of the week came together. This week, we discuss our top games, “dense street imagery," and first-person experiences with apps.
JOSEPH: This week we published Flock Wants to Partner With Consumer Dashcam Company That Takes ‘Trillions of Images’ a Month. This story, naturally, started with a tip that Flock was going to partner with this dashcam company. We then verified it with another source, and Flock confirmed it was exploring a relationship with Nexar. Pretty straightforward all in all. There are still many, many questions about what the integration will look like exactly, but my understanding is that it is what it looks like: Flock wants to use images taken from Nexar dashcams, and Nexar sells those cameras for use in their private vehicles.
There’s another element that made its way into a couple of paragraphs but which should be really stressed. Nexar publishes a livemap that anyone can access and explore. It shows photos ripped from its users’ dashcams (with license plates, people, and car interiors blurred). Nexar has then applied AI or machine learning to these which identify roadside hazards, signs, etc. The idea is to give agencies, companies, researchers, etc a free sample of their data which they might want to obtain later.

The popular Pick a Brick service let LEGO fanatics get the exact piece they wanted. It’s no longer available to US customers.#News #Trumpadministration
Add LEGO to the list of hobbies that Trump has made more expensive and worse with his tariff policy. Thanks to America’s ever shifting trade policies, LEGO has stopped shipping more than 2,500 pieces from its Pick a Brick program to both the United States and Canada. playlist.megaphone.fm?p=TBIEA2… Pick a Brick allows LEGO fans to buy individual bricks, which is important in the fandom because certain pieces are hard to come by or are crucial to build specific types of creations. LEGO, a Danish company, says that program will no longer be available to Americans and Canadians.
LEGO fansite New Elementary first noticed the change on August 25, four days ahead of the August 29 elimination of the de minimis trade exemption in the US. Many of the individual LEGO bricks in the Pick a Brick collection cost less than a dollar and it’s likely that the the elimination of the de minimis rule, which waived import fees on goods valued less than $800, made the Pick a Brick program untenable.
Some LEGO sets are simple boxes of a few pieces and others are vast and complicated reconstructions of pop culture icons that use thousands of individual bricks. The LEGO Millenium Falcon, for example, uses more than 7,000 individual pieces. When a specific piece goes missing it can be hard to replace. To service that need, third party services like BrickLink sell allow people to purchase individual pieces. LEGO’s in-house version of this is its Pick a Brick store, a place where enthusiasts could choose from thousands of different individual LEGOs and buy them piece by piece, usually for less than a dollar each.
A small subset of the Pick a Brick pieces, around 1,500 of them the store calls its bestsellers, are shipped to the United States from a warehouse in America. But the “standard” collection of less popular pieces ship from Denmark, where LEGO is headquartered. Those pieces, more than 2,000 of them according to fans, are no longer available in the United States and Canada.
The Pick a Brick website called this a service pause. “In the US & Canada, Standard pieces are temporarily unavailable. You can still shop our Bestseller range which includes thousands of the most popular bricks and pieces ready to order,” said a message at the top of the site.
LEGO fans online said that they saw their shopping carts emptied in the middle of building projects. “This is annoying. I just set up a big PAB order and then saved it. I just looked and 18 of my items are no longer available,” a comment in the r/LEGO community said.
“My whole Standard cart was wiped out... regret not ordering now. Had a lot of dual molded legs in there for Star Wars figure boot upgrades, looks like they're all gone now,” said another.
Others were upset that Canada was lumped in with the United States. “Why are we being caught up in Trump’s tariff shitstorm??? Ship the [Pick a Brick] orders straight to Toronto or something! We’re practically neighbours. We even share a land border with Denmark now,” one commenter said.“This is inherently unfair to Canadian buyers like myself. I primarily stick to lego trains, so now if I want to do any more custom builds, I need to search harder to get what I used to on PAB. Glad I got my last order in before this happened, it sucks that there's no Canadian warehouses,” said another.
The de minimis rule officially ended Friday, and we’re only just beginning to understand the ripple effects that change will have on the American economy. The only thing that is certain is that everything is getting more expensive and complicated. Some national mail carriers have stopped shipping to the U.S. entirely. Companies that move electronics, board games, and other small items on eBay are worried about the future.
The de minimis rule waived fees on more than 4 million packages every year, some of those were small amounts of plastic LEGO pieces. For now, LEGO fans in the US will have to find workarounds.
