Do you ever get tired of stressing your neck looking for planes in the sky? Worry not! Here is a neat and cheap Arduino/Ras Pi project to keep your neck sore free! [BANK ANGLE] presents a wonderfully simple plane tracking system using an affordable camera and basic microcontrollers.
The bulk of the system relies on a cheap rotating security camera that gets dissected to reveal its internals. Here stepper control wires can be found and connected to the control boards required to allow an Arduino nano to tell the motors when and where to spin. Of course, the camera system doesn’t just look everywhere until it finds a plane, a Raspberry Pi takes in data from local ADS-B data to know where a nearby plane is.
After that, all that’s left is a nifty overlay to make the professional look. Combining all these creates a surprisingly capable system that gives information on the aircraft’s azimuth, elevation, and distance.
If you want to try your hand at making your own version of [BLANK ANGLE]’s tracker, check out his GitHub page. Of course, tracking planes gets boring after a while so why not try tracking something higher with this open-source star tracker?
Nel "Giorno di Gerusalemme", mentre migliaia di israeliani celebravano l’occupazione dell’intera città avvenuta nel 1967 e sfilavano sventolando bandiere bianche e azzurre nella zona palestinese, il governo Netanyahu ha alzato il livello dello scontro diplomatico con l’Europa. Il ministro degli Affari strategici Ron Dermer, scriveva ieri Haaretz, ha lanciato un avvertimento diretto a Parigi e Londra: se riconoscerete lo Stato palestinese, Israele risponderà con l’annessione della Cisgiordania. Allo stesso modo, secondo Yisrael HaYom, ha fatto il ministro degli Esteri Gideon Saar inviando un messaggio simile alle controparti del Regno unito.
«Azioni unilaterali contro Israele saranno accolte con azioni unilaterali da parte di Israele», avrebbe minacciato Saar. Tel Aviv lancia così l’offensiva contro l’Europa, in vista del vertice previsto per il prossimo mese a New York, promosso da Francia e Arabia Saudita, dove il presidente francese Macron dovrebbe presentare la proposta di un riconoscimento coordinato dello Stato palestinese.
Riunito nel quartiere occupato di Silwan – nel sito archeologico della cosiddetta "Città di Davide", gestito interamente da un gruppo di coloni israeliani – il governo Netanyahu ha anche approvato una risoluzione per incentivare in vari modi il trasferimento delle ambasciate straniere a Gerusalemme.
Attualmente solo sei Paesi, tra cui gli Stati Uniti, hanno ambasciate nella città. Le Fiji si preparano ad aprirne una a settembre. Il resto del mondo non riconosce Gerusalemme come capitale di Israele.
Per il resto, il "Giorno di Gerusalemme" si è svolto secondo il solito copione. È stata l’abituale vetrina di suprematismo religioso, intimidazione verso i palestinesi e sfide alla legalità internazionale. Migliaia di manifestanti hanno lungamente scandito per le strade slogan come «Morte agli Arabi» e «Che il tuo villaggio possa bruciare». Quest’ultima invocazione è tristemente reale: ormai non passa notte in Cisgiordania senza che coloni israeliani assaltino villaggi e comunità palestinesi, incendiando case, automobili, frutteti e campi coltivati.
Giorni fa gli abitanti di Mughayer, o almeno una buona parte di essi, sono stati costretti a evacuare a causa di questi attacchi. Un’aggressione simile ha colpito ieri Khallet a Daba, nella zona ad alta tensione di Masafer Yatta (Hebron): 13 coloni, armati di bastoni e armi, hanno costretto due famiglie a fuggire. La nuova strategia dei settler consiste nel costruire avamposti a ridosso dei villaggi palestinesi più isolati, in modo da spingere i residenti a lasciare le loro terre. Nel sud di Israele sono scoppiate proteste contro la demolizione, iniziata la scorsa settimana, di 70 abitazioni beduine nel villaggio non riconosciuto dallo Stato di Qasr El Sir. La polizia ha arrestato due abitanti.
Star del "Giorno di Gerusalemme" anche quest’anno è stato il ministro della Sicurezza nazionale, Itamar Ben-Gvir, leader dell’estrema destra religiosa. Ieri all’alba si è presentato nel complesso della moschea di Al-Aqsa, guidando un’incursione di massa: oltre 1.400 estremisti hanno attraversato i cortili del terzo luogo sacro dell’Islam – per gli ebrei è il Monte del Tempio – issando la bandiera israeliana e recitando preghiere, in violazione dello status quo delle moschee. «Sono venuto a pregare per la vittoria nella guerra a Gaza», ha dichiarato Ben-Gvir, filmato mentre sventolava bandiere e distribuiva adesivi con lo slogan «Gaza è nostra per sempre». Al raid hanno partecipato anche il ministro del Negev e della Galilea Yitzhak Wasserlauf e i parlamentari Amit Halevi e Zvi Succot. Quest’ultimo, sventolando la bandiera israeliana, ha proclamato: «Il Monte del Tempio è ora nelle nostre mani».
Oltre alle bandiere di Israele, molti hanno issato vessilli con la scritta «Terzo Tempio», per sollecitare la costruzione di un nuovo tempio ebraico sulla Spianata. «Quella che gli arabi – i palestinesi, ndr – chiamano Al Aqsa non è altro che una parte dell’area dove sorgeva fino a duemila anni fa il nostro tempio. È venuto il momento di ricostruirlo, senza indugio», ci ha detto Yedidia Gabai, un manifestante giunto da una colonia in Cisgiordania. Intorno a lui decine di giovani danzato e urlato slogan tutto il tempo.
In quelle stesse ore, la deputata di destra Yulia Malinovsky ha simbolicamente occupato il quartier generale dell’Unrwa a Gerusalemme Est – l’agenzia che assiste i profughi palestinesi – trasformandolo nel suo "ufficio parlamentare".
Nel cuore della Gerusalemme vecchia, con i negozi tutti chiusi e gli abitanti palestinesi rintanati nelle case per evitare il peggio, la tensione è rimasta alta tutto il giorno. La polizia israeliana ha arrestato un palestinese che aveva difeso un commerciante dall’aggressione di giovani estremisti. L’uomo è stato picchiato dagli agenti, mentre gli aggressori si sono allontanati senza conseguenze. Sulla scena, i volontari del movimento arabo-ebraico «Standing Together», con i loro gilet viola, hanno tentato invano di impedire altre aggressioni. Loro stessi, insieme ad altri attivisti israeliani di sinistra, sono stati bersaglio di insulti e provocazioni da parte dei partecipanti alla «Marcia delle Bandiere». Arrivando alla Porta di Damasco della città vecchia, Danny Levy, capo della polizia, ha minimizzato l’accaduto. «Non abbiamo arrestato nessuno, solo qualche fermo tra gruppetti isolati», ha detto, aggiungendo di non aver sentito alcuno slogan anti-arabo. «Sapete, non sento bene, sono stato un artigliere nell’esercito», ha commentato sorridendo. Levy non ha neanche visto i fanatici del gruppo Im Tirzu esporre striscioni con le scritte «Nessuna vittoria senza Nakba» e «1967 – Gerusalemme nelle nostre mani, 2025 – Gaza nelle nostre mani».
A chiusura del «Giorno di Gerusalemme», è intervenuto anche l’altro leader della destra religiosa, il ministro delle Finanze Bezalel Smotrich. «Abbiamo paura della vittoria? Abbiamo forse paura della parola occupazione?», ha domandato Smotrich alla folla. Quindi ha insistito: «Stiamo forse colonizzando la Terra d’Israele? No, noi stiamo liberando Gaza. Stiamo trionfando sul nemico».
For those motorcyclists looking to get a classic American-style cruiser, often the go-to brand is Harley-Davidson. However, these bikes not only have reputations for being stuck in the past, both in terms of design and culture, but they also tend to be extremely expensive—not only upfront, but in maintenance as well. If you want the style without all of that baggage, you might want to try out something like this custom motorcycle which not only looks the part, it reduces those costs by being built around a hand truck.
By the end of the project, though, the hand truck does not retain much of its original form or function. [Garage Avenger] has cut and welded it essentially into a custom frame for the diminutive motorcycle, while retaining much of its original look and feel. Keeping up with the costs savings aspect of this project, the four-stroke engine was free, although it did take some wrenching to get it running and integrated into the frame. A custom axle, a front end from another bike, a gas tank from an online retailer (that needed re-welding), and some wiring finishes out the build.
With a fresh paint job to match the original color of the hand truck, it’s off to the track. Of course it doesn’t have quite the performance of most street legal motorcycles, including some quirks with the handling and braking, but for the trails around [Garage Avenger]’s home it’s certainly a fun transportation mode he can add to his repertoire. If this is your first time seeing one of his projects, be sure to check out his other work including this drifting shopping cart and this turbine-powered sled.
This entry into the 2025 Pet Hacks Contest is about bringing some fun feedback to normally silent plants. Fytó integrates sensors and displays into a 3D printed planter. The sensors read the various environmental and soil conditions that the plant is experiencing, and give you feedback about them via a series of playful expressive faces that are displayed on the screen embedded in the planter.
At the core of the Fytó is a Raspberry Pi Zero 2 W, which has plenty of power to display the animations while also being small enough to easily fit inside the planter without it growing in size much more than a normal planter would be. The sensors include a capacitive soil moisture sensor, a temperature sensor, and a light-dependent resistor. These sensors all provide analog outputs to relay their measurements and so there was an ADS1115 analog-to-digital converter board also included as the Raspberry Pi doesn’t have the required analog pins to communicate with them.
The fun animated faces are displayed with a 2-inch LCD display embedded in the planter. A small acrylic cover is placed in front of the LCD to help ease the transition from the printed planter to the internally mounted screen. The temperature and light sensors were also placed in openings around the planter to ensure they could get good environmental readings. There are six expressions the Fytó can express based on its sensor readings, ranging from happy when all the readings are in a good zone, to thirsty if it needs water or freezing when it’s too cold. Be sure to check out the other entries in the 2025 Pet Hacks Contest.

Genetic defects are exceedingly common, which is not surprising considering just how many cells make up our bodies, including our reproductive cells. While most of these defects have no or only minor effects, some range from serious to fatal. One of these defects is in the CPS1 gene, with those affected facing a shortened lifespan along with intensive treatments and a liver transplant as the only real solution. This may now be changing, after the first successful genetic treatment of an infant with CPS1 deficiency.
Carbamoyl phosphate synthetase I (CPS1) is an enzyme that is crucial for breaking down the ammonia that is formed when proteins are broken down. If the body doesn’t produce enough of this enzyme in the liver, ammonia will accumulate in the blood, eventually reaching levels where it will affect primarily the nervous system. As an autosomal recessive metabolic disorder it requires both parents to be carriers, with the severity depending on the exact mutation.
In the case of the affected infant, KJ Muldoon, the CPS1 deficiency was severe with only a low-protein diet and ammonia-lowering (nitrogen scavenging) medication keeping the child alive while a search for a donor liver had begun. It is in this context that in a few months time a CRISPR-Cas9 therapy was developed that so far appears to fixing the faulty genes in the liver cells.
CPS1 Gene Deficiency
The urea cycle. (Credit: Yikrazuul, Wikimedia) Despite its toxicity to living beings, ammonia (NH3) is an essential part of these same living beings, primarily in the form of amines (R-NH2), itself a rather indispensable part of amino acids, specifically the 22 proteinogenic amino acids from which proteins are formed. Just as ammonia is required for the amination process, so too is ammonia formed inside the body mostly as the result of transamination and deamination of these biogenic amines. This is a process that takes place primarily in the liver and involves the deamination of both the body’s own waste proteins as well as those from one’s diet.
Since only part of the ammonia can be reused for new amino acids, the rest has to be neutralized. Due to the toxicity of ammonia, blood levels have to be limited to <50 µmol/L or hyperammonemia will occur. This is where the urea cycle comes into play to maintain a healthy ammonia level.
The very first step of the urea cycle is the conversion of ammonia to carbamoyl phosphate: NH3 + HCO−3 + 2ATP → 2ADP + Carbamoyl phosphate + Pi Normally this is a very slow reaction, which is where the enzyme CSP1 comes into play as catalyst. In humans the gene for this enzyme is located on chromosome 2’s long arm, at locus 2q34. If there is a mutation in this gene that prevents it from working as a catalyst, ammonia levels in blood plasma will keep rising, eventually reaching levels where the nervous system is affected. In infants this is noticeable as lethargy, seizures and a lack of normal developmental milestones. Without treatment, developmental delay, intellectual disability or death affect 50% of babies.
Undoing A Mutation
When KJ was born on August 2024, it was noticed that he was lethargic, with stiff muscles and other worrisome symptoms. After a severe CPS1 deficiency was diagnosed via genome sequencing, KJ was hospitalized at only five months old. KJ’s only hope appeared to be a liver transplant and was put on the list for a donor organ, providing a slim hope at best. Meanwhile, a team of researchers started researching the cause of KJ’s CPS1 deficiency and the mutations behind it.
As described by Dr. Eric Topol in his summary of the (paywalled) paper by Gropman et al. in NEJM, both the father and mother were found to be carriers for CPS1 mutations, with the father carrying the truncating Q335X variant and the mother another (E714X). If either mutation could be corrected, the child would have one functional copy and theoretically be able to produce enough CPS1 to have a functional urea cycle without external assistance.
A complicating issue here is that despite the many reports of gene-editing with CRISPR the past years, there are various gradations, with what Dr. Topol refers to as CRISPR 1.0 through 3.0:
CRISPR 1.0: A CRISPR-Cas9 tool causes sufficient double-strand damage to disable the gene (knock-out). Crude and not relevant here. Also performed ex vivo.
CRISPR 2.0: Introduced single-strand cuts that allow for limited base editing, e.g. swapping A for a G.
CRISPR 3.0. Expands base editing to include multiple base pairs, both ex vivo and in vivo.
These methods have previously already been used ex vivo to create modified T-cells for CAR T-cell immunotherapy in the context of cancer treatments. In terms of in vivo treatments, there is the 2023 knocking out of PCSK9 liver protein to reduce bad cholesterol levels and the more recent base editing of the PiZ mutation responsible for liver and lung damage. There’s also ARCUS, which is a viral vector-based method of base editing that has seen use in fixing another urea cycle-related disorder.
Although only CRISPR 2.0 was needed here, what was unique in the case of KJ was that this would be the first fully personalized base editing therapy, applied in vivo and developed within the span of a mere six months.
Crossing All The Ts
K-abe base editor bound to target sequence of CPS1 (Credit: Gropman et al. NEJM, 2025) With how experimental this gene therapy for KJ’s CPS1 disorder was, the researchers had to go through the entire gamut of tests, including on animal models. With a base editor developed to target the father’s Q335X mutation and rewrite it to the correct base pairs, mice were bred that had the same CSP1 mutation, in addition to testing on non-human primates, all to validate the approach and gain FDA approval.
The base editor’s goal was to rewrite the the wrong bases at the Q335X location on locus 2q34. A concern with any application of CRISPR is so-called off-target edits, but the safety review seems to have passed here without serious issues.
Starting with a very low dose, blood plasma ammonia levels were carefully monitored with no noticeable changes. Three weeks later the second, higher dose was injected, with reportedly positive effects on the ammonia levels. A third dose was injected a while later, though the results of this aren’t know yet. In the absence of a liver biopsy it is hard to say in how far this is a true cure, as reported so far is a reduced need for medications.
Per reports, KJ is however doing better, hitting developmental targets and got over two viral infections, without an ammonia crisis. Further injections of the treatment will likely administered with an mRNA approach rather than the (presumed) virus vector used so far due to immunity concerns with a virus vector. Open questions remain regarding how many cells have been truly edited in KJ’s liver and what the overall effectiveness is.
This leads us to cautiously welcome this news as a step forward in personalized gene-therapy, while realizing that the road ahead for both KJ and the rest of us is still full of unknowns and challenges. That said, one can only hope for KJ’s best possible progress and ideally serving as a beacon of hope for others afflicted by genetic disorders like CPS1 deficiency.

The News
Surf is a new app by Flipboard, that describes itself as a browser for the open social web. The app allows people to build and browse custom feeds, that take in content from across the open social web. It can combine Mastodon posts with Bluesky posts, as well as RSS and more, into a single feed. With their most recent update, Surf has created Starter Sets for building custom feeds. Starter Sets are organised around various popular themes, like News, Tech or Sports. Within these themes, people can choose from a large variety of data sources to get started with building their own custom feeds. These custom feed sources can be from across the open social web and are modular. This means that a list of Mastodon accounts can be combined with a Bluesky custom feed to create a new single custom feed that consists of both data source. These custom feeds can also be published to Bluesky, so people who are not using the Surf app can also view these feeds.
Surf also now offers a variety of tools to manage the content of a custom feed. For example, a feed can be customised to include or exclude reposts, replies or adult content. There are also options to filter out posts about politics from the feed. The ability to filter about posts about Elon Musk is surely a popular feature as well. Surf categorises all posts via algorithmic clustering, which gives the ability to limit posts in a feed to a certain topic. This means that you can add an account to a feed, but only their posts related to the specified topic will be displayed. The app is currently in closed beta, and Flipboard is gradually onboarding more people from the waiting list.
PeerTube is starting a crowdfunding campaign for its mobile app. The first version of the PeerTube app was officially launched earlier this month. PeerTube is developed by Framasoft, a French non-profit organisation that builds a variety of open source software tools. The crowdfunding campaign is a way to raise money for the organisation, and also provides a way “to gauge public enthusiasm for the mobile application and the PeerTube project in general”. Some of the features that PeerTube wants to work on for its app are the ability to play videos in background, casting videos to TVs, managing channels and accounts directly from the app. Livestreaming from mobile is also being worked on, although Framasoft says they do not expect to release this in 2025. Framasoft says that these features will be worked on regardless of whether the fundraising goals are met, and that otherwise money from the generic Framasoft budget will be used, as a way to show their dedication towards PeerTube.
Mastodon has announced some upcoming new features that help server admins with the legal side. Server admins will be able to set a Terms of Service (ToS), besides server rules and a privacy policy. Server admins will also be able to set the server rules into multiple different languages. There will also be the option to set a minimum age requirement for sign-up for servers. Having a ToS is standard fare for any online platform, and multiple countries require by law that platforms have these. Europe’s DSA is fairly explicit about this, which states: “Providers of intermediary services shall include information on any restrictions that they impose in relation to the use of their service in respect of information provided by the recipients of the service, in their terms and conditions.” In that context, it is high time that Mastodon has added the ability for servers to set a ToS. Mastodon also says that they will provide a template for a ToS that other servers can use if they so desire.
A New Social, the organisation behind Bridgy Fed, has launched a dedicated page for people to manage their account bridging. Bridgy Fed is a piece of software that allows people to ‘bridge’ their account across multiple protocols. This allows people on the fediverse to interact with people on Bluesky (using AT Protocol). For this, people need to manually opt-in their accounts to be bridged to other networks (largely due to cultural reasons from the fediverse communities). Up until now, doing so was a fairly confusing process that involved manually following other accounts. With the new update, people can log in to Bridgy Fed with the account they want to bridge, and simply turn it on or off. It also has an easier option to update the handles for Mastodon accounts that are bridged to Bluesky. For example, by default my Mastodon account on Bluesky can be found at @[url=did:plc:43qcmg2xbxakj6mp4puqyayv]Laurens Hof[/url], which is a fairly cumbersome handle, to put it mildly. At the settings page I can now change it to any handle I want, similar to how any Bluesky account can change their handle. A New Social is also launching a Patreon as they are working towards financial sustainability, with plans to launch merch soon as well.
Ibis is a federated wiki platform that is currently in development, made by nutomic, one of the Lemmy creators. With the most recent update, Ibis wiki articles are now compatible with Lemmy, and can be viewed directly from Lemmy. One of the driving reasons for making Ibis is that nutomic views Wikipedia as untrustworthy. He also says that other centralised Wikipedia alternatives have failed to gain traction, and sees federation as a solution for this. For now, Ibis has the same problem of getting traction.

Plenty of readers will be familiar with CRT televisions, not least because many of us use them with retrocomputers and consoles. But perhaps fewer will have worked with CRTs themselves as components, and of those, fewer still will be familiar with the earlier generation of tubes. In the first few decades of color TV the tubes were so-called delta gun because their three electron guns were arranged in a triangular form. [Colorvac] has put up a video in which they demonstrate the reconditioning of one of these tubes from a late-1960s Nordmende TV.
The tube in question isn’t one of the earlier “roundies” you would find on an American color TV from the ’50s or early ’60s, instead it’s one of the first generation of rectangular (ish) screens. It’s got an under-performing blue gun, so they’re replacing the electron gun assembly. Cutting the neck of the tube, bonding a new neck extension, and sealing in a new gun assembly is not for the faint-hearted, and it’s clear they have both the specialist machinery and the experience required for the job. Finally we see the reconditioned tube put back into the chassis, and are treated to a demonstration of converging the three beams.

Gli analisti di Sekoia hanno scoperto che il gruppo di hackerViciousTrap ha compromesso circa 5.300 dispositivi di rete edge in 84 paesi, trasformandoli in una botnet simile a un grande honeypot.
Gli aggressori hanno sfruttato una vecchia vulnerabilità critica, lil CVE-2023-20118, per hackerare i router Cisco Small Business RV016, RV042, RV042G, RV082, RV320 e RV325. Si nota che la maggior parte dei dispositivi compromessi (850) si trovano a Macao.
“La catena di infezione consiste nell’esecuzione di uno script shell chiamato NetGhost, che reindirizza il traffico in arrivo da porte specifiche su un router compromesso verso un’infrastruttura simile a un honeypot controllata dagli aggressori, consentendo loro di intercettare le connessioni di rete”, affermano gli esperti. In precedenza, lo sfruttamento del problema CVE-2023-20118 era stato attribuito a un’altra botnet denominata PolarEdge e ora si ritiene che le due campagne malware possano essere correlate. Gli esperti ritengono che gli aggressori dietro ViciousTrap stiano probabilmente costruendo un’infrastruttura honeypot hackerando un’ampia gamma di dispositivi, tra cui router domestici, VPN SSL, DVR e controller BMC di oltre 50 marchi, tra cui Araknis Networks, Asus, D-Link, Linksys e Qnap.
“Questo schema consente agli aggressori di osservare i tentativi di sfruttamento in diversi ambienti, raccogliere exploit non pubblici e zero-day e riutilizzare l’accesso ottenuto da altri hacker”, spiega l’azienda. Secondo i ricercatori, tutti i tentativi di sfruttamento rilevati provenivano da un singolo indirizzo IP (101.99.91[.]151), con l’attività più antica risalente a marzo 2025. In particolare, un mese dopo, i partecipanti a ViciousTrap hanno utilizzato per le loro operazioni una web shell non documentata, precedentemente impiegata negli attacchi PolarEdge.
Anche all’inizio di questo mese sono stati osservati attacchi simili sui router Asus, ma da un indirizzo IP diverso (101.99.91[.]239), anche se in questo caso gli aggressori non hanno creato honeypot sui dispositivi infetti. Tutti gli indirizzi IP associati a questa campagna si trovano in Malesia e fanno parte di AS45839, gestito dal provider di hosting Shinjiru. Si ritiene che il gruppo responsabile degli attacchi sia di origine cinese, poiché la sua infrastruttura si sovrappone leggermente a quella di GobRATe il traffico viene reindirizzato verso più siti a Taiwan e negli Stati Uniti. “Lo scopo ultimo di ViciousTrap resta poco chiaro, ma siamo fermamente convinti che si tratti di una rete di ricognizione honeypot”, concludono i ricercatori.

Lo scandalo che circonda la fuga di dati di TeleMessage continua ad aumentare. Come rivelato di recentemente , degli hacker hanno avuto accesso a un archivio di corrispondenza che coinvolge oltre 60 dipendenti del governo degli Stati Uniti, tra cui rappresentanti della Casa Bianca, dei servizi segreti, di missioni diplomatiche, della dogana e dei servizi di risposta alle emergenze.
Tutti i messaggi sono stati pubblicati sulla piattaforma Distributed Denial of Secrets, un progetto specializzato nell’archiviazione di fughe di notizie ricevute nell’interesse pubblico.
Stiamo parlando di una corrispondenza frammentaria che copre circa un giorno: il 4 maggio. I dati intercettati includevano messaggi riguardanti la logistica di una visita di funzionari statunitensi in Vaticano e Giordania, nonché comunicazioni interne della Federal Emergency Management Agency.
Alcuni destinatari hanno confermato l’autenticità dei messaggi intercettati, tra cui un denunciante della FEMA e una società finanziaria. I telefoni di più di una mezza dozzina di funzionari corrispondevano effettivamente a quelli dei loro proprietari.
TeleMessage è finita sotto i riflettori dopo che un fotografo della Reuters ha immortalato l’ex Consigliere per la Sicurezza Nazionale Mike Waltz mentre utilizzava l’app durante una riunione di Gabinetto il 30 aprile. L’incidente ha sollevato interrogativi sul livello di sicurezza digitale all’interno dell’amministrazione Trump.
Waltz si è già trovato al centro di una controversia dopo aver aggiunto un giornalista a un gruppo Signal che discuteva di attacchi militari nello Yemen. Questo fu uno dei motivi delle sue dimissioni, ma Trump lo nominò subito ambasciatore degli Stati Uniti all’ONU.
Il servizio TeleMessage è una versione del popolare servizio di messaggistica adattata ai funzionari governativi, con la possibilità di archiviare i messaggi in conformità con le normative governative. È stato chiuso il 5 maggio, ufficialmente come “misura precauzionale”. Il suo proprietario, Smarsh, con sede a Portland, non ha rilasciato dichiarazioni in merito alla fuga di notizie.
I servizi segreti hanno affermato che il servizio è stato utilizzato solo da un gruppo limitato di dipendenti e che è in corso un’indagine interna. La FEMA ha affermato di non avere prove che le sue informazioni siano state compromesse, mentre i funzionari della CBP e del Dipartimento di Stato hanno rifiutato di rilasciare dichiarazioni.
Un’analisi dei contratti federali ha scoperto che TeleMessage è stato utilizzato anche dal Dipartimento della Sicurezza Interna e dai Centri per il Controllo e la Prevenzione delle Malattie (CDC). Questi ultimi hanno ammesso di aver testato la piattaforma nel 2024, ma di averla abbandonata. Una settimana dopo l’attacco informatico, la Cyber Defense Agency (CISA) ha consigliato a tutti gli utenti di smettere di usare TeleMessage finché non avessero ricevuto istruzioni ufficiali da Smarsh.
Sebbene i messaggi trapelati non contenessero dati particolarmente sensibili, l’ex specialista della NSA Jake Williams ha affermato che i metadati stessi (chi ha comunicato con chi e quando) rappresentano una risorsa di intelligence importante e potrebbero essere utilizzati a fini di controspionaggio.
The modern hacker and maker has a truly incredible arsenal of tools at their disposal. High-tech tools like 3D printers, laser cutters, and CNC routers have all become commonplace, and combined with old standbys like the drill press and mini lathe, it sometimes seems like we’ve finally peaked in terms of what the individual is realistically capable of producing in their own home. But occasionally a new tool comes along, and it makes us realize that there are still avenues unexplored for the home gamer.
After spending the last few weeks playing with it, I can confidently say the eufyMake E1 UV printer is one of those tools. The elevator pitch is simple: with a UV printer, you can print anything on anything. As you can imagine, the reality is somewhat more complex, but the fact that you can toss a three dimensional object in the chamber and spray it with a high-resolution color image with a few button presses holds incredible creative potential. Enough that the Kickstarter for the $1,700 printer has already raised a mind-boggling $27 million at the time of this writing, with more than a month yet to go before crossing the finish line.
If you’re on the fence about backing the campaign, or just have doubts about whether or not the machine can do what eufyMake claims, I’ll put those concerns to rest right now — it’s the real deal. Even after using the machine for as long as I have, each time a print job ends, I find myself momentary taken aback by just how good the end result is. The technology inside this machine that not only makes these results possible, but makes them so easily obtainable, is truly revolutionary.
That being said, it’s not a perfect machine by any stretch of the imagination. While I never ran into an outright failure while using the eufyMake E1, there’s a fairly long list of issues which I’d like to see addressed. Some of them are simple tweaks which may well get sorted out before the product starts shipping this summer, while others are fundamental to the way the machine operates and could represent an opportunity for competitors.
Theory of Operation
Before we go any further, I think it’s important to explain how the eufyMake E1 works. Not only because UV printers aren’t the kind of thing that most of us have had first-hand experience with, but because I want readers to understand how much the product gets right.
In the most basic case, you’ll open up the door of the E1, and stick an object on the bed. (There’s a larger bed that you can swap in for over-sized objects, but you have to run the printer with the doors open.) That’s a literal “stick”, by the way, as the bed is designed to be tacky to provide a bit of hold on smaller objects which might otherwise jump around as the machine moves. The E1 will then go through an automated process that includes flashing lights and sweeping red laser beams. This provides the machine with a 3D scan of the object on the bed, which is necessary for positioning the print head later on.
At this point, the software (available for Windows, Mac, and mobile devices) will present the user with a “bird’s eye view” of the bed and any objects on it. From here you can either use the basic art tools in the software, or more likely, import some artwork created in a more comprehensive piece of software. In either event, the process is the same, in that you virtually apply your artwork directly on the overhead image. Once you’re happy with how it looks, you hit “Print”, pick a few options relating to the target’s surface material and the print quality, and off it goes.
Printing is admittedly slower than I had expected. Depending on the image complexity, even a palm-sized job could take 20 or 30 minutes. While I never pushed it so far personally, I’ve heard from other testers that larger projects can take hours to complete. In that way, it’s a lot like a 3D printer — you aren’t the one that has to do all that work, so who cares if the process takes an hour or two, just let it run and come back to it later. In my experience, the results have always been more than worth the wait.
Practical Examples
I’ve said as much previously, but we don’t take reviews and hands-on articles like this lightly here at Hackaday. Companies offer to send us hardware on an almost daily basis, but we turn down the vast majority of them as we just don’t think they’re a great fit for our audience. Is the average Hackaday reader really going to be interested in a review of yet another 3D printer or laser engraver? Probably not.
So before we agreed to take a look at the eufyMake E1, Elliot and I talked a bit about how such a machine would be used in our community specifically. We came up with a few things we thought hardware hackers would want to do with this kind of capability, and I made sure to focus on those applications over the more “crafty” demonstrations that you may have seen elsewhere.
Full-Color PCB Art
While we’re starting to see board fabs support color silkscreens, it’s not a capability that’s necessarily ready for prime time. Beyond the mixed results we’ve heard from those in the community in terms of the quality of the resulting boards, there’s some unfortunate software/vendor lock-in that we’d just as soon avoid. So what if you could skip all that and simply put your professionally made PCBs in the E1 and have it apply your artwork to them?
In this fairly simple example I’ve taken one of the spare boards from my Soma FM badge and applied a few high resolution images onto it. I never really had any doubt that the eufyMake E1 could do PCB art, but still, it was extremely satisfying to see it in person.
Control Panels
High quality control panels have always been tricky to produce at home. Sure there’s ways to pull it off, such as the recent trick we covered that used specially treated inkjet printouts, but they tend to be time consuming and the results are highly dependent on the material you’re working working. With the UV printer, front panels are a breeze and you’ll get consistent results whether you’re working with plastic or metal.
For this example I came up with a flight-sim style panel inspired by various fighter jets. The workflow was actually quite nice: I designed the panel itself in OpenSCAD, and then exported it as both a 3D STL and 2D DXF file. The 3D file got printed out, and the 2D file was imported into Inkscape. With a 1:1 outline of the panel in Inkscape, I could position the text and images knowing they would line up perfectly with the real-world object. I exported my Inkscape design as an SVG, loaded it into the E1’s software, and applied it to the printed panel.
Truly Custom Keycaps
We’ve seen incredible interest in bespoke keyboards over the last few years, and customized keycaps are a big part of that. But even the most decked out keyboards are generally still using off-the-shelf keycaps. But why settle for that when you can buy blank caps and apply whatever text or artwork you wish on them?
These are such a perfect application for the E1 that I imagine it’s going to ignite something of a custom keycap revolution once the printer gets into consumer’s hands. Whether you want each key to be the face of a different anime character, or want all the legends to be in Comic Sans, you have complete control. They also serve as a great example of the fine detail work that’s possible on the machine.
The Perfect PCB Machine?
I know what you’re thinking: “Stop teasing me, can the damn thing make PCBs or not!” The short answer is yes…but the long answer is worth a bit more examination.
The UV print seems to work very well as an etch resist, as it was completely unfazed by its encounter with ferric chloride. In fact, the first challenge was figuring out how to get the stuff off after etching. Alcohol, turpentine, and paint thinner did nothing to it. Eventually I found that soaking the board in acetone will break down the bond between the printed layer and the copper — you still need to peel it off, but once you get under an edge with a razor blade it parts without too much trouble.
Early results look promising. The lines aren’t as clean as I’d like, so it will probably have problems with tight pitch parts, but the traces were intact down to 0.2 mm, and the pads for the SOIC8 footprint I picked as a test were properly isolated from each other. At this point, it’s a working PCB that’s at least as good as something made with the old school toner transfer method. But the E1 promises so much more. Putting the board back in the machine, I was able to spray it with additional layers that act as both a soldermask and silkscreen. While I want to experiment a bit more and refine the techniques involved, even this first attempt produced a remarkably professional looking board with very little manual effort on the user’s part.
That said, while this proof of concept shows it’s clearly possible to produce impressive boards on the machine, the process is made frustrating by various limitations of the hardware and software.
One-Off Versus Production
Let’s be clear, as a product, the eufyMake E1 is designed to let crafty folks put pictures of their kids on slate coasters and emblazon mugs with the logo of their favorite sports team. The software and hardware is clearly designed to make it as easy as possible to toss an object into the printer, get your image virtually aligned on it, and then spray it on. At this, the product excels, and I have no doubt it will be a commercial success.
But while hardware hackers are certainly not immune to the charms of putting memes and logos on their possessions, we also have slightly higher demands. If we’re talking about using it for producing PCBs, or even just adding art to existing boards, we’re looking for high positional accuracy and repeatability.
To that end, I have to report that the E1 is not particularly well suited to such technical tasks. It can be pushed into service, but there’s several aspects of the product that would really need to be addressed before this could be a workhorse for the hackerspace.
Lack of Physical Indexing
As it stands, the bed on the eufyMake E1 is a completely flat surface, with no provisions for work holding or indexing. You’re expected to visually align your print each time — workable for one or two copies of an object, but excruciating beyond that.
Now you might be thinking that this is an easy enough problem to remedy…but you’re probably forgetting that 3D bed scan. Any fixture you come up with to hold your object in position runs the risk of screwing up the scan and causing the print to abort. Even trying to tape a PCB down with blue painter’s tape would occasionally trigger an error during the scan as the machine couldn’t find a clearly defined edge.
As you’ll see below, I’ve had some success with very thin 3D printed fixtures that avoid the ire of the scanner. Long term, I’d like to see an alternate bed that resembled a CNC fixture plate, so that multiple parts can be held in position with low-profile pegs.
The Parallax View
At the suggestion of Thomas Flummer, I printed out a few thin (1.2 mm) jigs that could be taped down to the bed and help position multiple objects for batch processing. This is much better than having to eyeball things each time, but it uncovered a new issue.
For objects in the center of the bed, the optical alignment system works pretty well. It should get you within a millimeter or so on the first attempt, but it’s way off on the edges of the bed. Take a look at the following example: the in the software, both blue rectangles were perfectly aligned within the footprint of the 1206 LED:
As you can see the alignment on the board in the center is pretty locked in, but on the other board, it’s halfway out of the footprint. This might be close enough if you’re making grandma some Christmas ornaments, but it won’t cut it for SMD work.
The good news is that you can go back into the software and move objects at the sub-millimeter level by typing in the desired coordinates. This will cause the visual representation to become misaligned, but so long as you know where the target is in the real-world, it doesn’t matter. So if you can afford a bit of trial-and-error, it’s possible to get the alignment dialed in even across multiple objects on the bed.
The Shape of Things to Come?
As I said at the start, the eufyMake E1 is not a perfect machine. Beyond the major issues I’ve outlined here, there’s all sorts of weird quirks and limitations I’ve run into during my time with it. For example, why don’t the lights inside the enclosure turn on when the door is open? Why doesn’t the printer itself have a small screen to display status information? We won’t even get into the fact that all your interactions with the printer have to go through the cloud — there isn’t even so much as a USB port on the printer to allow local control.
But at the end of the day, I’m still extremely excited about this machine. The fact is, there’s really nothing else quite like it on the market, at least, not at this price anyway. It reminds me a bit of the MakerBot Cupcake 3D printer, or even the K40 laser. It represents such a huge leap forward in capability for the individual that it’s easy to excuse the rough edges.
Like those machines, I believe the eufyMake E1 will set many of the standards for the products that come after it. You may never own this particular UV printer, but I’m willing to bet that after a few hardware generations, when the cost of the technology is driven even lower thanks to increased competition, the printer that you do buy will be able to trace its lineage back to this moment.
La relazione è stata pubblicata il 27 maggio 2025 (è reperibile a questa pagina web direzioneinvestigativaantimafi…) e presentata dal Ministro dell’Interno al Parlamento. Analizza i fenomeni di criminalità organizzata di stampo mafioso. A differenza delle edizioni passate il documento:
offre un'analisi più ravvicinata nel tempo, coprendo l'intero anno 2024 per garantire un quadro più aggiornato,
è stato snellito e organizzato attorno alle diverse matrici mafiose, descrivendo la loro operatività a livello territoriale e le strategie di contrasto adottate,
offre una migliore visualizzazione delle dinamiche criminali per rendere le informazioni più immediate e comprensibili.
Aggiornamenti sulle interdittive antimafia: La relazione dedica particolare attenzione ai provvedimenti delle Prefetture e ai nuovi strumenti giuridici volti a reintegrare le aziende colpite dalla criminalità organizzata nel circuito economico legale. La dimensione internazionale
Nella relazione 2024 della Direzione Investigativa Antimafia emerge chiaramente come le attività non si siano limitate al solo ambito nazionale, ma abbiano avuto anche una forte dimensione internazionale. In particolare, il documento elenca operazioni condotte sia a livello europeo che internazionale, dimostrando un coordinamento con le autorità di altri paesi e con organismi internazionali. Questo approccio diventa fondamentale per combattere forme di infiltrazione mafiosa che travalicano i confini nazionali e si manifestano in settori strategici, dove il confine tra attività lecite e illecite diventa sempre più labile. Un esempio evidente riguarda il settore del gioco e delle scommesse online: la relazione evidenzia che, oltre agli interventi a livello locale, sono state realizzate operazioni specifiche che hanno avuto un focus sul mercato americano, riconosciuto come un'area particolarmente vulnerabile alle infiltrazioni e al riciclaggio di denaro. Queste iniziative internazionali prevedono uno scambio costante di informazioni, tecniche investigative e strumenti operativi con partner stranieri, al fine di interrompere le reti criminali e prevenire il consolidamento di rapporti economici illeciti che possano favorire l'espansione delle organizzazioni mafiose. L'approccio internazionale, dunque, non solo amplia il raggio d'azione della DIA, ma rafforza anche l'efficacia delle misure adottate sul territorio nazionale. La cooperazione transnazionale permette di intercettare flussi finanziari sospetti, monitorare attività economiche a rischio e sviluppare strategie congiunte che rispondano in tempo reale a fenomeni complessi e in rapido mutamento. Queste iniziative sottolineano l'importanza di una risposta globale alla criminalità organizzata, in un contesto in cui i mercati economici e tecnologici rendono il contrasto al crimine organizzato una sfida sempre più articolata. Vale la pena notare come la Direzione Investigativa Antimafia, oltre a intervenire sul territorio nazionale, stia sviluppando un robusto sistema di cooperazione transnazionale, anche quale leader della rete anti-mafia internazionale @ON. Questo approccio prevede:
Operazioni congiunte: La collaborazione con le autorità di altri paesi consente lo scambio tempestivo di informazioni e dati investigativi, fondamentale per intercettare e smantellare reti criminali che operano al di là dei confini nazionali.
Focus su settori sensibili: Alcuni interventi sono rivolti a mercati particolarmente vulnerabili, quali il gioco d'azzardo e le scommesse online, dove il riciclaggio di denaro si inserisce in circuiti internazionali complessi.
Tecnologie e metodologie condivise: L’impiego di strumenti avanzati per la raccolta e l’analisi dei dati permette alle autorità di monitorare in tempo reale flussi finanziari sospetti, integrando così le informazioni provenienti da svariate giurisdizioni.
Integrazione giuridica: Nuovi istituti e interventi normativi favoriscono non solo il contrasto diretto alle infiltrazioni mafiose, ma anche il reinserimento delle aziende “contaminate” nel circuito economico legale, garantendo un bilanciamento tra rigore nell’applicazione della legge e rispetto delle dinamiche di mercato.
Questi aspetti, sviluppati a livello internazionale, mostrano come l’evoluzione delle tecniche investigative e delle collaborazioni transfrontaliere stia diventando cruciale per contenere fenomeni criminali sempre più sofisticati e globalizzati.
