The Modern Data Stack is over, long live the Post-AI Data Stack🫡🤖 I wrote about how technological shifts change what a data team can build, the features of post-AI data stacks, what we've built at @tryramp, and what data teams can learn from @nbcsnl. iandmacomber.com/blog/post-a…

just got this pop up in @cursor_ai today, while I agree grok4.6 is the best coding model in terms of return on investment, I still need 1M context to fully migrate to it.

Always be kind to people, like this data visualisation is to our inflation rate by gently removing the 10-30% range and making it fairy dust ✨✨✨

and die Linke (far left party) is still leading the polls for the Berlin election🤦‍♂️🤦‍♂️
🇩🇪‼️🚨 GERMAN STATE RIPS OUT A SHOWER BECAUSE IT'S TOO LUXURIOUS! Germany tries to protect many neighborhoods from becoming fancy luxury areas. This manifests in situations like this: a guy who pays €950 rent built a shower for himself with his own money in a rental property. The state declared it’s too luxurious because now he has a shower and a bathtub. This is apparently too luxurious and would improve the rental property too much, which could lead to the neighborhood becoming too expensive. So the German state called in contractors to rip it out. And it’s gone. Yay! Peak EU

I moved almost all my data analysis workflow to @cursor_ai a couple of months ago, honestly it works great. Never had so much fun doing analysis. I loved & used notebook tools like @_hex_tech for a long time but I no longer see the point. Maybe that’ll change in the future 🤷‍♂️

If only there were a reliable data source indexing the App Store that could help settle this debate 😅 Is it worth selling apps to Spaniards? Are we really Europoors who refuse to pay for software? Well. @RevenueCat has the data. And the answer is annoyingly nuanced...
don't build apps in Spain - they don't convert - people ask you for the android version - doesn't matter how many times you change the paywall, if there's one, people close the app - wasting time building it - people don't want to pay for anything and they will blast you if they forgot about their free trial i hope those will help you not to build in this country

X received an order to restrict access in Türkiye to the official Presidential Candidacy Office account of the now-detained Mayor of Istanbul. Although Türkiye’s laws force us to comply with the order, we are challenging the order in court and, in the spirit of full transparency, are sharing the court order. This follows the similar order we received and complied with in May 2025 restricting access in Türkiye to a related account belonging to the Mayor. At that time we also issued a public statement via this account, expressed our strong disagreement, challenged the order in court, and shared the court order. Our challenge against this order remains pending before the Constitutional Court, awaiting a decision following our recent legal filings. These orders require X to block content in Türkiye that is available in the rest of the world. Not complying with these orders can trigger severe sanctions, including throttling of the entire platform in Türkiye. X challenges these orders in court because we believe keeping the platform accessible in Türkiye is vital to supporting freedom of expression and access to information. X will continue legally challenging requests to remove content in Türkiye and around the world when those requests do not align with principles of free expression, due process, or other local laws.

My third app, Nonogram Museum, is live 🎉 @dambil and I built this one together. It combines classic nonogram puzzles with retro technology 📟 It’ll also be one of my #Shipaton submissions! Give it a try and let me know what you think 🙏 apps.apple.com/app/nonogram-…

Uzun süredir üzerinde çalıştığım bir projeyi bugün duyurmanın mutluluğunu yaşıyorum. Bilge ve Yonga: 7-12 yaş çocuklar için 32 kitaplık bir bilgisayar mimarisi serisi. Tamamı ücretsiz, bugün yayında. Yıllardır üniversitede bilgisayar mimarisi anlatıyorum. Öğrencilerin çoğu bir işlemcinin içinde ne olup bittiğini ilk kez ikinci ya da üçüncü sınıfta duyuyor. Oysa bu konuların özü, doğru anlatıldığında bir çocuğun rahatlıkla kavrayacağı şeyler: bir anahtar açılır ve kapanır, her şey sıfır ve birle yazılır, işlemci bir buyruğu alır, anlar ve yapar. Seride meraklı bir çocuk olan Bilge ile küçük robot arkadaşı Yonga var. Bilge sorar, Yonga anlatır. Kumdan yonga nasıl çıkar, bilgisayar neden ısınır, önbellek ne işe yarar, bir program nasıl makine diline dönüşür. Her kitabın sonunda kısa bir "Bugün Ne Öğrendik?" özeti var. 426 sayfa, her sayfanın kendi çizimi var. Kapaklarla birlikte 458 özgün görsel. Tarayıcıda okunuyor, isteyen PDF ya da EPUB indiriyor. Bir şeyi de açıkça söyleyeyim. Bu seriyi birkaç yayınevine anlattım, destek çıkan olmadı, çoğundan yanıt bile gelmedi. Açık erişimi ilke olarak zaten tercih ediyorum, kitaplar bu yüzden ücretsiz. Ama çocukların kitabı eline alıp sayfasını çevirme deneyimini yaşayamıyor olması benim için bir eksiklik. Ülkemizde yayıncılığın mürekkep ve kağıt masrafını hesaplamanın ötesine geçmesi gerekiyor. Bir eserin değeri satacağı kopya sayısıyla ölçülmüyor. Basmak isteyen bir yayınevi çıkarsa kapım açık. Tek koşulum, kitapların dijitalde ücretsiz kalması. bilgeveyonga.oguzergin.net

Not sure if people feel the same, but the joy I get from my job (data stuff) has at least 3x'ed since agents started handling the actual coding. It feels like someone took away the parts I didn’t enjoy and left me with all the fun. Grateful to the folks at OpenAI / Anthropic.

is it normal to wait 7 days (and still counting) for app store review? Sounds unreasonable to me

a couple of months ago got the cheapest mac mini (16gb ram + 250gb hd) to run openclaw etc., now I am not running openclaw etc anymore but use mac mini all the time for iOS development and regret buying the cheapest mac, need to juggle ram and disk usage all the time.
