Who wants to know how Gemma 4 works?
This visual guide breaks down the new architectures and how they process text, images, and (for the smaller models) audio.

@NovemberTwoKilo @LundukeJournal I mean he need to just load the kernel in memory from /boot. Put the kernel in a reserved partition supported and that is all, your system than can run on whatever filesystem. If you had raid 0 is what you used to do

@LundukeJournal Logical. Boot loader is for booting. Nothing else. Needless complexity invites vulnerability.

Ubuntu is removing a huge number of supported file systems from their shipping version of the GRUB boot loader.
LVM, LUKS, btrfs, hfsplus, xfs, zfs, & mdraid.
All are being removed and will no longer be available for booting systems.
Once again, tried and true code is being tossed out. This time in favor of systemd for booting.
They are also disabling images (like JPG) in GRUB. Because, assumedly, Ubuntu hates joy.

It genuinely breaks my brain to imagine what 1400 hours of annual sunshine must be like to live in.
When going to college in Chicago, I really struggled with the seemingly endless gray of the winters. Chicago gets 2500 sunshine hours!

@Cr1st14nM3s14n0 Self hosted gitlab, in generale un modello locale al tuo enviroment lo puoi far girare (eg qwen) , poi sei sempre su aws/gcp/azure.. ma ci siamo tutti no?

Detto ciò: è intrinsecamente avere la codebase su github? no. Esistono alternative? Ni (sono costose, poco scalabili e difficilmente integrabili).
Esiste quella che si chiama analisi di rischio:
Il rischio di un abuso su codebase aziendali è basso su github e altissimo su llm.
Italiano
Sono stanchino di dover dar retta a gente che crede di capirci di informatica perchè ha aperto un github con 4 script di python convinta di aver sviluppato un prodotto sw.
Comparare la sicurezza dei dati aziendali su un github con quella di un LLM è da cretini.

sì certo, stai tranquillo, adesso ti apro la code-base. No, ma sono tranquillissimo che i dati li copi ma poi non li condividi con nessuno. Poi fra qualche mese scopriamo che c'è una backdoor per l'NSA e i segreti industriali magicamente vengono anticipati. Certo, certo.

Europe has Mistral (Large 3 / Magistral series – frontier-level, open-weight, crushes a lot of US closed models on efficiency + multilingual, EU data sovereignty baked in) Europe has Aleph Alpha (Luminous family – explainable, enterprise-focused, German precision) Europe has EuroLLM series (22B+ open models trained on EU supercomputers, multilingual for all 24 official languages) Europe has OpenEuroLLM project (massive collab for transparent, truly open foundation models) Europe has Hugging Face as the literal open-source hub everyone (including US labs) relies on. USA has the hype + VC money printer. China has scale + state backing. Europe has privacy, open weights, and the will to regulate you into compliance while quietly building stuff that actually works in regulated industries (Accenture just bet big on Mistral for enterprise Europe). So yeah, Europe “has” the bans… but also the models that won’t get your data shipped to California.

E se iniziassimo ad usare tutti Mistral che é europeo ed (almeno in parte) open source?

@steipete I wonder, are we just back to telnetting into someone else’s box and calling it progress? Maybe with a dash of RPC for flavor.

@Cr1st14nM3s14n0 @Pinperepette Allora se paghi, di solito fanno in modo che i tuoi dati restino sul tuo account e non lascino europa. Detto questo, son d’accordo, in qmbito enterprise se già si usassero per migliorare i processi, documentare e renderli più efficienti..
Italiano
@Pinperepette non è uno strumento utilizzabile in ambiente critico perchè gli intervalli di confidenza per gestire la varianza nelle risposte richiedono troppo tempo per calcolarli.
-io continuo a dire che sono un grande strumento, ma as is va bene in domini di business non cruciali.

Si ma Cristian questa critica vale per il prompt da chat, non per l’uso aziendale. Le aziende non chiedono e basta: usano agenti orchestrati, vincoli, controlli incrociati, metriche e validazione. Se ti affidi a un LLM senza guardrail per fare risk forecasting, il problema non è l’AI....o sbaglio ?

@zain_hoda You are building data analytics tooling with ai, so appreciate the enthusiasm, but how many times you faced not reliable data because no SOR exist or too many existed, so are you really thinking an agent will solve this? Or we will end up multiple agents holding multipe truths?

Nascondersi dietro al “System of Record” potrebbe non garantire più le attuali rendite di posizione dei grandi sistemi software corporate.

I have never understood the massive economic gap in Italy.
Why is the North, with its various industries, one of the wealthiest areas in Europe, while the South remains so extremely poor?
Same country, same language, same culture, same laws and taxes. Can someone please explain?

Ryanair CEO addresses his recent spat with Elon Musk in new press conference:
"The Starlink people believe that 90% of our passengers would happily pay for wifi access. Our experience is tells us less than 10% would pay; He (Elon) called me a r*tarted twat. He would have to join the back of a very very queue of people that already think I'm a r*tarded twat, including my four teenage children. But we do want to thank him for the wonderful boost in publicly. Our bookings are up 2-3% in the last few days. So thank you to Mr. Musk, but he's wrong on the fuel drag. Non European citizens cannot own a majority of European airlines, but if he wants to invest in Ryanair we think it would be a very good investment."

@levelsio @nizbuilds Lol, Fiat with the punto Punto was coming out in the 90s with reliable and cheap cars. The engine itself is a Fire Engine, simple and easy to work on. I agree new cars are comfortable easier safer. But that punto is so simple and bare, that he is probably content with it
English
I think it's a Southern European thing maybe
They have some pride that is above their logical sense, so they are so proud of their car that they really think it's better
They also don't care about money, so they don't see why a EUR 65,000 Tesla Y from 2025 would be preferable over a EUR 600 Fiat Punto from 1999
English
Today my Portuguese Uber delivery driver came to my house and asked me why I had a Tesla Y 2025 AWD and explained why his 1999 Fiat Punto was superior because it was built to last and that I should sell my Tesla Y and buy a car like his "it's also cheaper so better for you"

I like and respect Elon, and I'm grateful to be on this platform. But when he claims 𝕏 Chat is "much more secure than email," I feel obligated to explain the technical reality to my audience.
That statement is true in the same way a screen door is more secure than no door. But that's not the comparison anyone should be making.
1. 𝕏 Can Read Your Messages
𝕏 recently added safety numbers, which is a step forward. But here's the catch: your private key backups are stored on 𝕏's servers. Safety numbers help detect external hackers, but they cannot protect you if 𝕏 itself or a rogue insider, or a government with a warrant.
@signalapp's safety numbers work because your keys never leave your device. There is nothing for Signal to turn over, even if compelled.
2. No Forward Secrecy
From 𝕏's own documentation: "If the private key of a registered device is compromised... an attacker would be able to decrypt all Encrypted Direct Messages."
One key compromise exposes your entire message history. Signal's Double Ratchet generates new keys for every message. Compromise one key, you get one message. Past messages stay encrypted. This has been the standard in secure messaging for over a decade.
3. The "Juicebox" Vulnerability
𝕏 stores your private keys on their servers using a system called Juicebox. Cryptographer @matthew_d_green's analysis suggests this implementation is software-only, lacking Hardware Security Modules (HSMs).
A 4-6 digit PIN does NOT help protect this. That is trivial to brute-force if 𝕏 (or an attacker with server access) disables the rate limiting.
4. Full Metadata Exposure
𝕏 explicitly states metadata isn't encrypted: who you message, when, and how often. As former NSA director Michael Hayden famously said: "We kill people based on metadata." Signal uses sealed sender technology to hide even this information.
5. NOT Open Source
𝕏 promised to open source XChat and publish a whitepaper in June 2025. Neither has happened. Signal has been open source and audited for over a decade.
The Bottom Line:
I'm not saying don't use 𝕏. I'm saying don't use 𝕏 Encrypted DMs for anything you wouldn't post publicly.
For actual private communication, use @signalapp. It's free, works on all platforms, and the cryptography has withstood a decade of scrutiny from academics and nation-states alike.
Elon Musk@elonmusk
Send files via 𝕏 Chat with full encryption. Much more secure than email!

@jmrphy So you got married, you agreed to have a child with your wife, but now you resent it takes work and time to grow a human? Possibly deformed by american WASP culture, but i would try to do things you love with your child. He did not ask for you as father, you asked for him.
English
Am I just a monster? It's been 4 years since I became a father and I'm beginning to fear for my soul. The truth is I just don't like being around kids for very long. Historically, this is not uncommon among fathers, but today it feels almost illegal. It's causing me a lot of confusion and anguish.
The ideal amount of time I would like to spend playing with my kids is probably about 70-140 minutes a week—roughly ten minutes each day, maybe 2x/day, taking breaks from work. My feelings of love toward them are perfectly strong, but if I have to watch them or entertain them for more than about 10 minutes my blood starts to boil. I just want to be working, or accomplishing something. I try to be grateful, but it doesn't work.
It's 9 AM this morning, Saturday, January 3. It's a sunny, warm day here in Austin, and my four-year-old son is begging me to play catch in the street. I was drinking coffee, still waking up, so I didn’t really feel like it, but at this age his desire to play is insatiable. He begged and begged, so I conceded, and with a smile. I have no problem being a kind and loving father, the problem is only that I do not enjoy it. It's not that I'm trying to maximize my personal pleasure; it just seems wrong that I experience so little delight when my dad friends all claim to experience so much.
It was beautiful. We live on a picturesque, tree-lined block. I am even relatively relaxed from the holiday rest. Playing catch with your son is supposed to be an iconic, peak experience. Yet for every single minute, on the inside, I just don't want to be there. I want to be drinking my coffee in peace. Then I feel guilty and absurdly ungrateful, and ashamed, when we're done. I know that when he is a teenager, I'll long to have these days back. I have all of this perspective rationally, and I've been very patient and steadfast trying to digest it, but nothing fixes me emotionally.
Am I a terrible person? Or is my feeling within a certain range of historically normal and it's modern parenting norms that are off? Whether it's my fault or not, I don't even care, I just want to figure this out. Something is wrong and I no longer have the excuse of being new to this.

@HarryScoffin Italian here , every flat is effectively a freehold and work
Are managed by a named administrator and fees need to be voted. Meetings happens quarterly and normally involve heated discussions, but is so
Much easier also
To renovate vs medieval leasehold!!
English
People are often reluctant to buy flats in England and Wales because of the legal structure that governs them. Leasehold typically places control in the hands of a third-party landlord, who determines the service charges required to maintain the building. If those charges rise sharply, they can significantly undermine the value of what is often the largest purchase of a person’s life.
By contrast, in Scotland flats are generally held under the tenement system, which provides democratic resident control and avoids leasehold landlordism. As a result, flats account for around 45% of the housing stock. In England, where leasehold rules, flats make up less than 25%.
Internationally, most jurisdictions use schemes analogous to commonhold, such as strata title and condominium ownership. England and Wales are the outliers, persisting with a wealth-eroding leasehold system in which outside investors retain the whip hand, reducing flat owners to the legal status of tenants.

@Victoria_Spratt @theipaper It’s so wrong, we have so many examples in British architecture of brilliant, human, community enhancing flats. Why can’t we do better?!

Italian nuclear exit, how to shoot yourself in the feets.. leveraging fear
Emil Jacobs@collectifission
The narrative that we can't rely on nuclear because France had a single (1) bad year in 2022 feels so forced and tired. Look at the numbers from below site of the Fraunhofer Institute: France has had another excellent year exporting electricity to needy Germany and other places. Out of the 92 TWh of net exports, it went to: - Germany: 11.25 TWh - Switzerland: 19.94 TWh (which directly sent it to Germany, let's be real) - Belgium: 12.03 TWh - UK: 22.53 TWh - Italy: 26 TWh (them being a pioneer in nuclear exits). Nuclear France is truly a pillar of the European grid.
