Finally visited the @Cloudflare office in Lisbon 🧡 Been running my projects on Cloudflare since ~2014, and we use it at @MacPaw too. Thanks Oleh for the tour! P.S. Their office seagull is basically our office cat 🐦 #WebSummit #Cloudflare

Opened the @WebSummit 2026 key speakers page 👀 18 of the first 20 are from China 🇨🇳 2 from the US. 0 from Europe. At the biggest tech conference in Europe. Looks like cars aren’t the only thing China is winning in Europe

Sure, it’s budgets and a push for market share, not merit. OpenAI and Anthropic aren’t even there.

Added GitHub developer and company rankings, plus embeddable achievement badges, to srclog.com last night. Used to be weeks. Now it’s 30 min. Next steps - improve github crawler

Launched a small experiment: macappia.com 🗺️ A catalog of Mac apps sorted by what you want to do, not by category. Fun part: in the first 24 hours, the first visitors to index it weren't #Google . They were AI crawlers #Claude #ChatGPT. That's the web now.

2. Service pages /service-health/cloudflare — individual pages for all 41 services: current status, 90-day GitHub-style uptime calendar, response time chart, incident log. Main goal: SEO for queries like "cloudflare status history", "aws outage log".

Spent two evenings of my sabbatical building this: internetvitals.com - a real-time health dashboard for the internet's backbone, framed as a hospital patient monitor. 41 backbone services (Cloudflare, AWS, Azure, GCP, GitHub, Stripe, major DNS providers) → one weighted

You won't believe what shows up in web server logs — someone apparently wrote a bot trying to escape #belarus 😅 And yeah, the internet is just drowning in bots and scanners these days 🤖 Half the job is just blocking them 🚫

I waited 7 years for my sabbatical at @MacPaw . The plan was the Camino de Santiago and making music nobody would hear. Instead — I'm spending 5 weeks shipping my side projects like a hackathon. Here's why 🧵

2/ Quick context: 20 years in web dev. Engineering Manager by day. On the side — ~60 domains, a portfolio of AdSense sites, and ~100 ideas waiting in the backlog. For the last 3-4 years I barely touched any of them.

Пару тижнів тому зламав ногу катаючись на ментахелс ліках / на велі =( Але нічого, тепер по вихідним гуляти не виходить і влаштовую собі міні вікенд хакатони. Пишу щось “для душі”, поки по будням намагаюсь стати класним Engineering Manager-ом. 1/X

Головне що трафік повернувся на свої значення попередні
Internet disruptions in #Ukraine continue, but most of the regions recovered from yesterday's military air strikes in several cities. radar.cloudflare.com/ua In Ukraine in general, traffic dropped on Oct 10, 07:30 UTC ~35%. This morning (08:00 UTC) seems normal. (👇 thread)

заява президента Франції до Французької армії 🇺🇦🇫🇷 facebook.com/100044157757824… невже підтримка силами нас буде? 🤔
🇨🇭 Switzerland now is not the time for neutrality. If you don't freeze Russian money and sanction Russian companies, you help Putin to slaughter a democratic nation in Europe #StandWithUkraine @ignaziocassis @ParmelinG @alain_berset @s_sommaruga @Violapamherd #UeliMaurer 🙏
Швецарія (яка навіть при гітлері була нейтральна!) і так проти свинособак #StopRussianAggression
⚡️⚡️The President of Switzerland announced that the country will join the EU sanctions against Russia. Significant, considering Switzerland’s traditionally neutral stance
