Doufám, že jste všichni pochopili, že jestli chcete dneska ještě dostat večeři, musíte sepsat a zdokumentovat veškerou svojí knowhow, nahrát jí na jedno místo ve strojově čitelném formátu, a dát k ní neomezený přístup Samovi a Dariovi a jeho modelům. A pak vás určitě nenahradí.

@lavrton I’m curious, what’s the difference compared to the other existing libs causing the performance difference?

While text rendering is hot on X. 🚀 I built render-tag: the fastest way to draw HTML rich text on canvas. Pure 2D API, no SVG/foreignObject workarounds. 5x faster than the SVG approach, even more with large fonts. Built this to solve my biggest pain point working on a web design editor. Building a canvas app? Take a look!

Escape game How to get from Hanoi to EU avoiding Doha is full of surprises every day. Azerbaijan Airlines seemed like a viable option yesterday. Risk increases after today 🤨

I need help because I’m too stupid: every razor I buy it just sucks… This one does not turn on while charging. Battery life is abysmal. Guys, I need recommendations. Best razor for the best beard?

vectorcharts.com, my nautical chart API, is pretty mature now. I'm looking for early-adopter customers who are building maritime software and need to add Nautical Charts to their app. If you're trying to build a maritime-related UI, I want to hear from you!

@lavrton I hired a sales person. It helps having them on the call, starts with chit-chat, builds credibility. Depends how good are you in this. I'm for the technical topics.

I am at the point where I have huge number of on-boarding and sales-related emails from potential clients of Polotno Editor SDK. So I have less time for dev-related work. How to resolve the issue without hiring a sales person? Or this is the way?

@lavrton I'm about to go the same path, considering ~x100 of the cloud service. Self-hosted is an enterprise plan for those who have concerns about using an external cloud service, want to have control over deployment or custom configuration.

Celkem by mě zajímalo, co je za tímto bugem u meteoradaru chmi_cz, zda je to problém algoritmu nebo dat nebo zda je to třeba OK. Někdy se v případě predikce zblázní a úplně změní směr. Tohle je starší ukázka.

- Property-based access control is a worthy candidate for application multi-tenancy instead of node labels - New variations of shortest path queries are compatible with Quantified Path Patterns neo4j.com/release-notes/…

Looking forward to upgrade to @Neo4j 5.21 🚀 - CALL { …​ } IN CONCURRENT TRANSACTIONS promises to improve performance of intense write operations instead of sending individual queries in parallel over the network 1/2
