Tested Opus 5.5 on complex gap analysis between prototype and already drifting production code. The concepts and nuances it picked up were spot on. During grilling session I had to correct just two out of 25 questions. Comparable with Fable, but with better understandable lingo.

This is a view from our new CNBC / StockStory office in Prague. I'm pretty excited about what's ahead, growing the engineering team. We're hiring 🚀 https://t.co/a7mkaLGDHq

Advanced Protection on #Pixel phones running #Android 16 can block some eSIM activations because it disables 2G. The 2G network is required for initial activation — once that’s done, you can switch to 4G or 5G normally.

This week we are rolling out new article type on @StockStoryHQ: earnings call analysis

@EVchargingCZ @fuksaaa Pokud jsou pripojeny oba CCS porty, nabijecka se prepne na 2x30kW

@honzip @LiborFleis @min_dopravy https://t.co/ZmBWAenMEH Jedná se o motory N53 a N43.

[Radek Strnad @randomf]

@LiborFleis N53 dle diagnostiky přepíná do stratifikovaného režimu už 2 minuty po startu. Vtipné je, že software řídící jednotky je tak citlivý, že při trochu nestandardních hodnotách zůstane v čistě homogenním režimu, takže paradoxně horší vozy projdou. Já si asi před STK odpojím NOx sensor

Happy birthday to @princeofpersia, released on Apple II 35 years ago today!💾🕹️

I tell the behind-the-scenes story in my 1980s "The Making of Prince of Persia" journals,📘 and in my new graphic novel memoir "REPLAY."📕You can check out both books here: https://t.co/G8rjzp07KB

@DopravniPeklo @michalblaha Je to TomTom Traffic Index https://t.co/e2XTyF10PT
Pak má podobné datasety i https://t.co/sWeJVn9i4f nebo Waze https://t.co/aSlKn7Y979

[Radek Strnad @randomf]

@michalblaha @DopravniPeklo To ano, ale naopak v centru automobilová doprava trvale klesá od roku 1999 (zdroj poslední ročenka TSK) i přes nárust obyvatel. V součtu jsme +-3% na stejných číslech od roku 2009. Že se každoročně zhoršují dojezdové časy (publikuje TomTom) má na svědomí snížení kapacity cest.

@EVchargingCZ Uz jsou aktivni? Na webu Shellu jeste nejsou zanesene.

@AkciovyGURU Chtějí si zopakovat stejný výtah jako u $TSLA

@Hrubis1 To je skvělý posun. ID.3 pre-FL by to v tomto počasí dala s odřenýma ušima za 22 kWh / 100km. Jaká je čistě dálniční spotřeba?

Upgraded my old @turris_cz router with Wi-Fi 6 kit to give it couple more years of service. The signal range is better, speed has improved and all devices on the network are nearing the line limit.

This is a performance of @StockStoryHQ stock picks since we started publishing our theses last summer. Including the underperforming first one, they are roughly doubling the #SP500 performance.

6) Boost performance with materialized views. Add a 'last updated' timestamp, and use it for monitoring stale data. Consider failing queries based on the timestamp.

[Radek Strnad @randomf]

4) Avoid nested queries. Leverage "SELECT DISTINCT ON", "GROUP BY" or "PARTITION BY" instead if possible.

[Radek Strnad @randomf]

5) Consider re-designing tables for more performance. Normalize to optimize for writes, denormalize for read-heavy apps.
