I keep saying this, this idea of just vibing and accepting everything that is written by the LLM will cost us later, what we are seeing now is nothing compared to the damage that will happen in the future when most systems has just being vibe coded
This week's incidents are a reminder about why "human in the loop" is important. Ie, read your damn code. Understand your systems. Know whats in there and what can go wrong. No LLM advancement will replace human understanding.

So basically, today PHP got two critical bugs that let anyone run code on your server without even logging in, which is bad, and then the details leaked before the patch was even out, which is worse, and it works on WordPress and MediaWiki and Magento and Joomla and Laravel, and Censys says like 1.5 million servers are running a version with no fix, so the NSA was like "take your system offline," and the FBI was like "take your system offline," and CISA and the UK and CERT-EU were all like "take your system offline," and then the Prime Minister of Japan, the actual Prime Minister, posted at 5:55 in the morning telling 48.8 million people to take their system offline, so everyone took their system offline, like the Dutch cybersecurity agency took its own website offline, and the Dutch parliament went offline, and the Port of Rotterdam went offline, and Finland and France and Denmark started pulling government sites, and Wikipedia went down, and Archive.org went down, and Asana and GOG and Something Awful went down, and the University of Vienna's webmail went down for some reason, and that's just PHP. Because GitLab also dropped a CVSS 10.0, which is the highest score they give out, for a bug that's been there since 2014, so that's every self-hosted GitLab for twelve years, and then LiteLLM 1.107.0 got hijacked and shipped a credential stealer and a remote access trojan in every single wheel and the Docker images, including latest, and you didn't even have to import it, just installing it was enough, and it's the second time this year, and then Railway paused every deployment on the entire platform because someone got into the environment variables, so now everyone has to rotate every secret they've ever stored there, and TiDB Cloud said someone was walking around inside with stolen credentials for basically a month and an extortion group says they took 10.6 terabytes, and Zeabur got breached for the second time in two months and is just shutting down, like the whole company, and Node.js patched remote code execution and a TLS bypass, and CISA says Plex is being actively exploited, and someone took over 300 Tor exit relays to steal SSH passwords, and SafePay ransomware has hit over 600 critical infrastructure orgs, and India's biggest bank filed a data loss incident, and Japan has been in an official state of emergency in cyberspace since October 9, which honestly explains the 5:55 AM post. Oh, and eMudhra, a certificate authority that's issued over 60 million certificates, whose entire job is proving websites are who they say they are, was supposed to be using private keys that are random numbers over a hundred digits long, and one of them was 4. Just 4. And the others were like 66 and 237. Anyway, it's Wednesday.

Railway too ? If you have a server running on Railway, take precautions and rotate your credentials immediately, as they may have been compromised. Remove any exposed secrets from Railway and revoke the affected API keys and tokens. I received this message a few minutes ago, and Railway appears to be down as well. Stay safe out there, guys. 🚨

Excited to share that Evolution has joined Nuvion @ournuvion 🚀 When we started Evolution, we had a simple vision: make moving money across borders easier and more accessible for individuals and businesses, enabling them to go Global from wherever they were. We believed that accessing global financial services shouldn’t be complicated simply because of where you live or where your business operates. What started as a platform for exchanging digital assets grew into something much bigger. We built infrastructure that enabled people and businesses to hold multiple currencies, receive international payments, move money across borders, and access financial tools that were previously out of reach. Along the way, we served thousands of users, processed millions of dollars in transactions, and learned firsthand what it takes to build financial infrastructure in emerging markets. But more importantly, we saw just how much work remains to be done. As we continued building, one thing became increasingly clear: solving cross-border banking challenges at scale requires more than a great product. It requires strong financial infrastructure, regulatory reach, and the ability to serve businesses wherever they operate. That’s what makes this next chapter with Nuvion particularly exciting. Nuvion is building an AI Powered Global banking platform for ambitious businesses, bringing multicurrency accounts, international payments, FX, virtual cards, and stablecoin infrastructure together in one place. Our visions have always been closely aligned, and joining forces gives us the opportunity to pursue what we started at Evolution on a much larger scale. For me, this is an opportunity to take everything we’ve learned building Evolution and apply it to something with the infrastructure, reach, and ambition to serve businesses around the world. I’m especially excited that members of the Evolution team are continuing this journey with me at Nuvion. We’ve spent years building, solving difficult problems, and learning together. Now we get to bring that experience into a much bigger mission. To everyone who believed in Evolution, our early customers, investors, partners, community, and the incredible people who contributed to our journey: thank you. You trusted us when we were still figuring things out, challenged us to build better, and helped turn an idea into a real business. I’m incredibly proud of what we built, and even more excited about what comes next. Evolution was never just about building another fintech company. It was about making global banking accessible for the people and businesses who need it. That mission continues at Nuvion. The Job is just starting

This is already stressful as it is, but as you said, it’s the nerdy way. Imagine doing this on mobile or trying to download videos. 😭 I use savefrom.net for both videos and pictures. It’s super easy!
How I save images on IG… the nerdy way

If you’re a software engineer, please ignore the noise about AI replacing engineers and double down on data, platform and infra related engineering. This means your fundamentals need to be solid.

I started listening to this System Design podcast a few months ago, and it’s been one of the best investments I’ve made in myself this year. My understanding of software architecture and optimization has improved massively. In a world where AI can write code, your edge is knowing how to design systems and solve problems. 🤷‍♂️

Solana just halved its target slot time. 400ms → 200ms 2.5 → 5 target slots per second 1.6s → 0.8s validator leader windows For perspective, Ethereum still runs 12-second slots. That's 60x longer per slot than Solana's new target. Solana's first full epoch averaged 218.3ms. We're now looking at more frequent transaction executions, quicker feedback, fresher onchain data for defi.. That's just block production btw. Alpenglow targets ~150ms finality. Not live yet. Solana will be the home of onchain finance.

Y'all aren't thinking about ai productivity correctly. I have one customer support guy at boot dev, he can handle the entire support load (low 8 figure revenue) in just a few hours a day Theres literally no business value to me in automating even 80% of his work, because I'll still need him for that last 20% HOWEVER he's not online 24/7. There are a subset of tickets, that, with a really good model, we could give answers to that are no worse than his, nearly instantly. inj other words, you need to be more focused on using AI to improve products and services - and less concerned with cutting marginal costs.

Something must be wrong with me 😭 Earlier today, I was just reading an article about PostgreSQL indexing. Next thing I knew, I was reading different SQL commands, then diving into how indexes work, B-trees, blocks, heap files, and now I’m here trying to understand how databases work from the ground up. 😪 Sometimes I hate this. I’ll go looking for one small piece of information and somehow end up down a rabbit hole trying to understand the entire architecture. 🤦‍♂️

So emotional right now 😢😭 The GREATEST OF ALL TIME 🐐👑. You made my youth so much more fun and filled with happiness. Thank you, Lionel Andrés Cuccittini Messi. With the eyes of a child, I watched you play with that leather ball and fell in love. I’m glad I chose you, because my life has never been the same since. ❤️🐐
