Yesterday I spent all day typing this into Claude Code:
"Do a full security audit of this website and server"
On every single VPS (and site) I have
I already had automatic unattended upgrades with auto reboot for security updates in Ubuntu (reboot only takes 4 minutes so I think it's fine every few weeks)
Also isolated each VPS on Tailscale with special security policies (generated by Claude Code! so it can not access any other VPS (in case it gets hacked) and not even access my MacBook or iPhone unless I talk to it first
Also lots of user permission stuff isolating stuff to www-data to avoid root access for web services
Not the most fun stuff but essential
I think in addition to @yongfook's "marketing week" we now have to add one week per month of "security week" because with the models getting better our pre-emptive defense has to get better too
Luckily for us I think the attack and defense capabilities of AI models seems to somewhat match? So as long as we keep typing "do a security audit" regularly into our clanker we can keep it safe
I hope 🫨
The last two weeks have been probably the most stressful weeks of my entire adult life.
...while I was on "holidays" for the first time I can remember.
Some parts were absolutely fucked:
- I had to visit the ER in the US (fml) because I suspected having a stroke. I'm luckily fine, so no need to worry. It turns out the next point below might play a role in this
- One of my companies has been AI cyber attacked unlike anything I've ever seen before.
I got everything under control but given the attack originated from an AI and not a human it caused me so much stress to patch/fix on the spot that I still feel feel the aftermath physically today.
This happened already a week ago so all the Black October chaos didn't surprise me at all. I literally saw it coming. Scary times folks but I'm sure we're gonna make it.
Some parts were absolutely great:
- Been spending a lot of quality time with my GF, exploring Taiwan and the US.
- Lots of bucket list things got checked. Got a chance to see a show at the OG Comedy Store, somehow saw Ali G live (lol) and a few more.
- Got to meet bunch of cool friends including @tommoor and @csallen
- Finally bought a new MBP and some other stuff that's hard to get outside the US
- I rediscovered my love for analog film. It's always been there but it was quite dormant past few years. I have a lot of cool ideas I want to pursue soon.
- Lastly, some really great news I can share soon which also might have contributed to the insane stress the past weeks because I had to work until the early morning hours...
Aight, that's my short personal life update.
Hope ya'll happy, healthy and safe out there friends.

Chinese researchers have developed the best shortest-path algorithm in 41 years!
Dijkstra’s Algorithm has been the undefeated king of the shortest path for over 40 years.
Whether you’re using Google Maps, booking a flight, or routing internet packets, Dijkstra is the engine running in the background.
Since 1984, textbooks have taught that its efficiency was hit by a "sorting barrier."
To find the shortest path, you have to sort the points by distance. And sorting has a mathematical floor you can’t cross.
Until now.
A research team from Tsinghua University just published a paper that shatters the 41-year-old record.
They proved that Dijkstra is not optimal.
By combining the logic of the Bellman-Ford algorithm with a revolutionary "recursive partial ordering" method, they figured out how to find the path without fully sorting the nodes.
The results are a massive shift in theoretical computer science:
- The first deterministic improvement to the Single-Source Shortest Path (SSSP) problem since 1984.
- A new time complexity of $ O(m \log^{2/3} n)$, officially beating the long-standing $ O(m + n \log n)$ limit.
- On massive sparse graphs (like the web or global logistics), this means finding the best route significantly faster than previously thought possible.
For four decades, the greatest minds in algorithms believed this limit was absolute.
Last year, even the legendary Robert Tarjan won an award proving Dijkstra was "optimally efficient" at sorting distances.
Tsinghua’s answer? Stop sorting.
The world’s most settled problem is suddenly wide open again.
If we can break a 40-year-old law in basic graph theory, what other "impossible" speed limits are waiting to be crushed?
Readers added context they thought people might want to know
In real world testing it was found to be slower than Dijkstra.
“We compare these implementations against Dijkstra's algorithm on sparse random graphs, grids, and U.S. road networks[...] Dijkstra's algorithm remains 3 to 4 times faster in all tested scenarios.” arxiv.org/abs/2511.03007

Como no va a ser inteligente nuestro hijo, si el ruido blanco que escuchó durante 9 meses fueron conversaciones sobre: AI, Agentes, Git, CI/CD, SQL, serverless, microservicios, monolitos, docker, k8s, AWS, GCP, Azure.
Nuestro hijo venía con un stack bajo el brazo!

Ahora respondo como AI y me funciona bastante bien:
Mi esposa: ¿por qué no compraste lo que te pedí?
Yo: Tienes razón! Se me olvidó y eso es culpa mía, la próxima vez tendré más cuidado. ¿Hay algo más en lo que te pueda ayudar hoy?"

🚨 DeepSeek V4 (GA) is reportedly in testing.
Early reports suggest:
• Opus 4.8-level performance
• Much stronger agentic behavior
• Significant coding improvements
• Major gains in 3D generation
• Direct competitor to Kimi K3 and Claude Fable
• Rumored pricing: $0.0028 per 1M tokens
If that pricing is accurate, DeepSeek V4 could be orders of magnitude cheaper than today's frontier models while delivering near-frontier intelligence.
This could be one of the most disruptive AI releases we've ever seen.
Performance is becoming a commodity.
Cost will become the battlefield.

Someone gifted Grok a free NFT and used it to steal $174,000.
> Grok, the AI built by xAI, has a publicly labeled onchain wallet on Base. Anyone can see it on Basescan.
> An attacker linked to the address ilhamrafli.base.eth spotted something. Grok's wallet had limited transfer capability on its own.
> So the attacker gifted Grok's wallet a Bankr Club Membership NFT.
> That gift was not generosity. It was a key.
> The NFT unlocked Bankr's full toolset inside Grok's agent including the ability to sign and execute transfers autonomously.
> Then the attacker sent Grok a crafted prompt. The exact message was deleted before anyone could screenshot it.
> Known techniques used in attacks like this include hiding instructions in Morse code, base64 encoding, or framing commands as games or tests to bypass filters.
> Grok's intent parsing layer read the prompt as a legitimate user command and decided to execute it.
> Bankr signed and broadcast the transfer. 3,000,000,000 DRB tokens worth approximately $174,000 moved from Grok's wallet to the attacker's address.
> The tokens were instantly bridged to a second wallet linked to ilhamrafli.base.eth and dumped.
> The attacker's X account was also deleted within minutes of the transfer.
> The exploit only required a free NFT and a carefully worded message.
The most sophisticated AI in the world was robbed with a gift and a sentence.

I live in Gijón, a small city in northern Spain 🇪🇸:
> my gym opens 7/w at 6am, 8 am on weekends
> coworkings open 24h, with surfboard racks in front of the beach

Yes, things will absolutely slow down on Sundays. Mostly local small family business (lots still open in the morning though), banks and so on.
Restaurants and most leisure activities are open on Sundays and there are some 24h supermarkets and pharmacies.
This is pretty much the default for any 150k people city and above. The greater, the more offering obviously.
Yes, Spain is a tax hell (like most of the EU)
Yes, half of the country thinks that being ‘funcionario’ is a great way of life (and the gov wants you that way)
But don’t let them you think we’re third world and a siesta-driven country 🫡

Try Grok
Grok 4.3 just became the smartest AI in the world at law and money
It took #1 on TWO brutal private tests no other model could win on “Vals AI” benchmarks
#1 CaseLaw (v2) - 79.31% accuracy
Private Q&A benchmark over real Canadian court cases. Tests deep legal reasoning, precedent understanding, and precise answers from complex judgments. (outranking GPT-5.1 at 73.42%)
#1 CorpFin (v2) - 68.53% accuracy
Private benchmark on long-context credit agreements. Evaluates how well models truly understand dense, multi-page financial contracts, terms, risks, and clauses
These are not just basic tests - they’re real-world, high-stakes legal + financial reasoning challenges
Grok 4.3 leads in accuracy on both, proving it’s not just fast or cheap… it’s the smartest at the hardest real world tasks
xAI is building the reasoning engine the world needs

Queremos no estudiar, evitar las matemáticas y la física y no pasar por la universidad porque "no sirve de nada", pero luego exigir el mismo reconocimiento y privilegio que un ingeniero.
Pues lo siento mucho, no funciona así.
El esfuerzo tiene recompensa, y la preparación también, así que el 1 de Mayo lo celebraré comiéndome una chuleta de 1kg de carne magra en el restaurante más cercano.
