«Non viviamo in un’epoca di cambiamento, viviamo un cambiamento d’epoca»: questa affermazione, più volte ribadita da papa Francesco, nell’ambiente missionario viene ripresa «per rafforzarne un’altra di uso frequente: il “cambiamento di paradigma” della missione di oggi. L’uso di queste due espressioni consacra, da una parte, l’idea di processo radicale di trasformazione e, dall’altra, quella di cambiamento di modello di missione, quasi ci fosse un solo, unico modello» (p. 9). L’A., missionario comboniano portoghese, «si propone di riflettere sui modelli di missione che si sono imposti nella Chiesa del postconcilio e di illuminare questa riflessione con il contributo degli ultimi pontificati, in particolare di quello francescano» (p. 11).

Il saggio si articola in 13 capitoli, di cui i primi tre chiarificano i termini utilizzati nel titolo: in quale senso si parla di «modelli» e cosa si intende per «riconfigurazione». La riflessione non «ha pretese teologiche o ecclesiologiche quanto al contenuto, né accademiche quanto alla forma. Cercherà di costruirsi come saggio esplorativo, dalla finalità divulgativa» (p. 15). In questa prospettiva, i modelli di missione vanno intesi «come concetti di riferimento spirituale, fonte di ispirazione e di motivazione che orientano l’impegno» (p. 16). L’intento è dialogico e propositivo, «offrendo soprattutto le ragioni per capire i diversi modelli e, eventualmente, preferire l’uno o l’altro» (p. 18), con una particolare attenzione all’insegnamento di papa Francesco: «La conversione (termine da lui usato) può essere vista come punto di partenza che porta alla riconfigurazione (termine del nostro sottotitolo) della vita della Chiesa in tutte le sue dimensioni» (p. 20).

Un capitolo è dedicato all’insegnamento di Francesco su temi che attraversano in modo trasversale i diversi modelli. La gioia del Vangelo, la Chiesa in uscita, i quattro princìpi enunciati nell’Evangelii gaudium (cfr nn. 222-237), che «possono essere applicati con profitto a ogni modello della missione e possono fungere da bussola» (p. 27); la santità come il volto più bello della Chiesa, che si può riprendere «anche in relazione ai missionari e ai modelli di missione.

L’A. esamina sei modelli possibili di missione, per ciascuno dei quali viene data una breve presentazione, richiamato il fondamento biblico, delineato un sommario percorso storico, illuminato l’apporto di papa Francesco, valutati i punti forti e i punti deboli.

Si susseguono i modelli di missione come annuncio, come incontro, come servizio, come fraternità, come liberazione, e infine, come ecologia integrale, che «appare come un modello in progress» (p. 156). Gli Istituti missionari sono nati nell’Ottocento e rispondevano alle esigenze di un contesto sociale ed ecclesiale molto diverso da quello attuale. La crisi del paradigma missionario ne interroga l’identità e stimola l’approfondimento del carisma fondazionale: «Il papa sembra suggerire un cambiamento di prospettiva: non siamo noi a possedere definitivamente un carisma, è il carisma che, in modo dinamico e come grazia divina, possiede noi nelle stagioni della nostra vita, nelle varie epoche e generazioni di un istituto o comunità» (p. 185). Da qui anche la riflessione sul rapporto tra il carisma e l’istituzione, che fa fatica a tenere il passo: «Troviamo più ispirazione, carisma e profetismo riguardo alla missione nelle parole e nei gesti di papa Francesco che non nelle strutture deputate all’accompagnamento e al sostegno della missione» (p. 201).

Secondo l’A., la riforma della Curia con la costituzione Praedicate Evangelium, se da una parte sembra proporre la riconfigurazione missionaria della Chiesa, istituendo al primo posto fra i dicasteri quello per l’evangelizzazione, presieduto direttamente dal Pontefice, dall’altra «non mancherà di suscitare qualche viva inquietudine tra i missionari» (p. 203). Questi già con la riforma della Curia di Giovanni Paolo II erano passati dalla giurisdizione canonica della Congregazione «De Propaganda Fide», sotto il cui patrocinio erano nati e ricevevano sostegno, a quella per gli Istituti di vita consacrata e le Società di vita apostolica, che di fatto ha sfaldato l’attenzione alla missione e ai missionari e spostato l’accento della loro identità: «I missionari sono passati così a essere visti come religiosi (anche) missionari, anziché missionari (anche religiosi)» (p. 199).

«Quella degli istituti missionari nati nell’Ottocento è una storia bella, che risveglia la speranza e ci fa sperare in cose nuove» (p. 210), in una Chiesa che non ha una missione, ma è missione. Come scrive il card. José Tolentino de Mendonça nella Prefazione: «La complessità della presente stagione non dovrebbe […] essere letta come un ostacolo, ma come una opportunità» (p. 6).

If you’re going to be a hacker, learning C is a rite of passage. If you don’t have much experience with C, or if your experience is out of date, you very well may benefit from hearing [Nic Barker] explain tips for C programming.

In his introduction he notes that C, invented in the 70s by Dennis Ritchie, is now more than 50 years old. This old language still appears in lists of the most popular languages, although admittedly not at the top!

He notes that the major versions of C, named for the year they were released, are: C89, C99, C11, and C23. His recommendation is C99 because it has some features he doesn’t want to live without, particularly scoped variables and initializing structs with named members using designated initializers. Also C89 is plagued with non-standard integer types, and this is fixed by stdint.h in C99. Other niceties of C99 include compound literals and // for single-line comments.

He recommends the use of clang arguments -std=c99 to enable C99, -Wall to enable all warnings, and -Werror to treat warnings as errors, then he explains the Unity Build where you simply include all of your module files from your main.c file.

It’s stressed that printf debugging is not the way to go in C and that you definitely want to be using a debugger. To elaborate on this point he explains what a segfault is and how they happen.

He goes on to explain memory corruption and how ASAN (short for Address Sanitisation) can help you find when it happens. Then he covers C’s support for arrays and strings, which is, admittedly, not very much! He shows you that it’s pretty easy to make your own array and string types though, potentially supporting slices as well.

Finally he explains how to use arenas for memory allocation and management for static, function, and task related memory.

It’s often said that one should not reinvent the wheel, but that doesn’t mean that you cannot change how the use of said wheel should be interpreted. After initially taking the rather zany concept of a monowheel for a literal ride, [Sam Barker] decided to shift gears, did a ‘what if’ and slapped a second monowheel next to the first one to create his diwheel vehicle. Using much thicker steel for the wheels and overall much more robust construction than for his monowheel, the welding could commence.

It should be said here that the concept of a diwheel, or dicycle, isn’t entirely new, but the monowheel – distinct from a unicycle – is much older, with known builds at least as far back as the 19th century. Confusing, self-balancing platforms like Segways are also referred to as ‘dicycles’, while a diwheel seems to refer specifically to what [Sam] built here. That said, diwheels are naturally stable even without gyroscopic action, which is definitely a big advantage.

The inner frame for [Sam]’s diwheel is built out of steel too, making it both very robust and very heavy. High-tech features include suspension for that smooth ride, and SLS 3D-printed nylon rollers between the inner frame and the wheels. After some mucking about with a DIY ‘lathe’ to work around some measurement errors, a lot more welding and some questionable assembly practices, everything came together in the end.

This is just phase one, however, as [Sam] will not be installing pedals like it’s an old-school monowheel. Instead it’ll have electrical drive, which should make it a bit less terrifying than the Ford Ka-based diwheel we featured in 2018, but rather close to the electric diwheel called EDWARD which we featured back in 2011. We hope to see part two of this build soon, in which [Sam] will hopefully take this beast for its first ride.

For those local to the Philadelphia area, a “jawn” can be nearly anything or anyone — and at least for this weekend, it can even be a hacker con building up steam as it enters its third year. Kicking off this Friday at Arcadia University, JawnCon0x2 promises to be another can’t-miss event for anyone with a curious mind that lives within a reasonable distance of the Liberty Bell.

The slate of talks leans slightly towards the infosec crowd, but there’s really something for everyone on the schedule. Presentations such as Nothing is Safe: An Introduction to Hardware (In)Security and Making the GameTank – A New, Real 8-Bit Game Machine will certainly appeal to those of us who keep a hot soldering iron within arm’s reach, while Rolling Recon & Tire Prints: Perimeter Intrusion Detection and Remote Shenanigans via Rogue Tire Stem RF and Get More Radio Frequency Curious will certainly appeal to the radio enthusiasts.

Speaking of which, anyone who wants to make their interest in radio official can sit in on the Saturday study group led by Ed “N2XDD” Wilson, the Director of the American Radio Relay League (ARRL) Hudson Division. After lunch, you can take your exam to become a licensed ham, and still have time to check out the lockpicking demonstrations from the local TOOOL chapter, the Retro Show ‘n Tell area, and rummage through the self-replenishing table of free stuff that’s looking for a new home.

Attendees can also take part in a number of unique challenges and competitions inspired by the shared professional experience of the JawnCon organizers. One of the events will have attendees putting together the fastest Digital Subscriber Line (DSL) broadband connection, as measured by era-appropriate commercial gear. Easy enough with a spool of copper wire, but the trick here is to push the legendary resilience of DSL to the limit by using unusual conductors. Think wet strings and cooked pasta. There’s also a Capture The Flag (CTF) competition that will pit teams against each other as they work their way through customer support tickets at a fictional Internet service provider.

We were on the ground for JawnCon in 2024, and even had the good fortune to be present for the inaugural event back in 2023. While it may not have the name recognition of larger East Coast hacker cons, JawnCon is backed by some of the sharpest and most passionate folks we’ve come across in this community, and we’re eager to see the event grow in 2025 and beyond.

Generally people equate the Arduino hardware platforms with MCU-centric options that are great for things like low-powered embedded computing, but less for running desktop operating systems. This looks about to change with the Arduino Uno Q, which keeps the familiar Uno formfactor, but features both a single-core Cortex-M33 STM32U575 MCU and a quad-core Cortex-A53 Qualcomm Dragonwing QRB2210 SoC.

According to the store page the board will ship starting October 24, with the price being $44 USD. This gets you a board with the aforementioned SoC and MCU, as well as 2 GB of LPDDR4 and 16 GB of eMMC. There’s also a WiFi and Bluetooth module present, which can be used with whatever OS you decide to install on the Qualcomm SoC.

This new product comes right on the heels of Arduino being acquired by Qualcomm. Whether the Uno Q is a worthy purchase mostly depends on what you intend to use the board for, with the SoC’s I/O going via a single USB-C connector which is also used for its power supply. This means that a USB-C expansion hub is basically required if you want to have video output, additional USB connectors, etc. If you wish to run a headless OS install this would of course be much less of a concern.

I clienti britannici di Renault e Dacia sono stati informati di una violazione dei dati personali. La violazione, secondo quanto riferito, si è verificata presso un fornitore terzo.

La casa automobilistica francese (Dacia è una sussidiaria di Renault), che impiega oltre 170.000 persone e produce 2,2 milioni di veicoli all’anno, ha riferito che la perdita ha interessato solo i clienti delle sue divisioni nel Regno Unito. Ha sottolineato che l’incidente era collegato a un “appaltatore terzo” non identificato e che i sistemi di Renault non erano stati interessati.

“Siamo spiacenti di informarvi che uno dei nostri partner è stato vittima di un attacco informatico, che ha causato il furto di dati personali di alcuni clienti Renault UK”, ha affermato l’azienda in una nota.

Tra i dati compromessi caduti nelle mani degli hacker rientrano:

• nome e cognome;
• pavimento;
• numero di telefono;
• indirizzo e-mail;
• indirizzo postale;
• Codice VIN del veicolo;
• numero di registrazione.

Questo set di dati potrebbe essere utilizzato da aggressori per attacchi di phishing, frodi e ingegneria sociale. Renault sottolinea che le informazioni bancarie e finanziarie dei clienti non sono state compromesse.

L’azienda aggiunge che l’appaltatore interessato ha contenuto l’incidente ed eliminato la minaccia sulle sue reti. Le autorità di regolamentazione britanniche, tra cui l’Information Commissioner’s Office (ICO), sono già state informate dell’attacco informatico.

Si consiglia ai clienti di prestare attenzione, di non rispondere a chiamate o e-mail sospette e di non condividere le proprie password con nessuno.
