(Neural) Networking with a Business Card
A PCB business card is a great way for electrical engineers to impress employers with their design skills, but the software they run can be just as impressive as the card itself. As a programmer with an interest in embedded machine learning, [Dave McKinnon] wanted a card that showcased his skills, so he designed one that runs voice recognition.
[Dave] specifically wanted to run a neural network on his card, but needed to make it small enough to run on a microcontroller. Voice recognition looked like a good fit for this, since audio can be represented with relatively little data, a microphone is cheap and easy to add to a circuit board, and there was already an example of someone running such a voice recognition network on an Arduino. To fit the neural network into 46 kB, it only distinguishes the words “one” through “nine,” and displays its guess on an LED seven-segment display. [Dave] first prototyped the system with an Arduino, then designed the circuit board around an RP2040.
The switch from Arduino to the RP2040 brought with it a mysterious change: it would usually recognize the word “eight,” but none of the other numbers. After much investigation, it turned out that the new circuit was presenting samples at a much higher rate than the older one had, which was throwing the network off. [Dave] increased the sampling period and had the user speak the numbers slowly, which solved the issue.
The microcontroller was well chosen; the RP2040 is good enough for machine learning that there are dev boards explicitly designed for it, and even comparatively less powerful Arduino boards can do surprisingly good voice recognition. On the hardware side, [Dave] cited some of the Linux business cards we’ve seen as inspiration.

“What is the score of your sportsball game?” I ask jovially.
No one responds.
“Would anyone like to play Quidditch?” I ask.
One of the other prisoners nods toward a recreation yard guard, who approaches me from behind and hits me with a baton.

I'm getting cooked in the `clang-tidy` comments.

I opened up Steam to see if any games were calling out to be played, and realized I bought AseSprite at some point, and it also became available on Linux (via Proton, I assume, as it's wrapped in a Windows looking window). But, I can't figure it out? It's complicated and clearly not designed for retro machine targets, though I've seen people talk about using it for making C64 sprites, I just can't see how. I reckon I'll keep plodding along with my editor that does only/exactly what I want.

Poliversity è stato aggiornato alla Release 4.5.1 + Glitch Soc. con i post di citazioni, una soluzione per le risposte mancanti e altro ancora
Questo post viene pubblicato anche sul gruppo Activitypub @fediverso del nostro server *Feddit.it***
Come i più attenti tra voi avranno notato, non abbiamo aggiornato questo server alla Release di Mastodon 4.5.0. Questo è dovuto al fatto che da una parte aspettiamo sempre un po' a installare nuove release, a meno che non si tratti di patch di sicurezza; In secondo luogo perché la versione 4.5.0 aveva mostrato fin da subito la necessità di una nuova release per la correzione di alcuni piccoli bug.
Ecco quali sono le novità di questa releaseCitazione Post: Consenso e Conversazione
Le citazioni sono state fondamentali per approfondire le discussioni online e sono ora disponibili in Mastodon 4.5. Questa versione non solo introduce funzionalità di authoring, ma anche meccanismi che danno priorità alla sicurezza e alla privacy degli utenti. Gli autori possono limitare e disabilitare le citazioni, sia a livello globale nella nuova pagina "Impostazioni predefinite di pubblicazione", sia individualmente per post specifici. Inoltre, una volta citati, possono facilmente revocare l'utilizzo del loro post.
Recupera tutte le risposte: completamento del flusso di conversazione
Gli utenti sui server che eseguono la versione 4.4 e precedenti hanno probabilmente riscontrato la confusione di vedere risposte apparire su altri server ma non sul proprio. Mastodon 4.5 verifica automaticamente la presenza di risposte mancanti al caricamento della pagina e nuovamente ogni 15 minuti, migliorando la continuità delle conversazioni nel Fediverso.
A questo link potete trovare tutte le altre nuove implementazioni valide per la release 4.5.0:
