Interpelacja o własnościowych formatach plików Microsoftu (doc, xls, ppt, rtf) w Krajowych Ramach Interoperacyjności, którą złożyliśmy z @martastozekMarta Stożek

Zainspirowana artykułem @rysiekMichał "rysiek" Woźniak · 🇺🇦

Łapska bigtechów sięgają tak głęboko administracji publicznej, że aż nie chce się wierzyć.

Zobaczymy, czy ministerstwo w ogóle widzi w tym jakiś problem 🤔

Czy zdołamy uwolnić polskie instytucje od Googla i Microsoftu?

Centralny Ośrodek Informatyki chce budować rozwiązania dla polskiej administracji na otwartym oprogramowaniu. Projekt ma mieć poparcie ministra cyfryzacji. Świetnie! Czas najwyższy na uniezależnienie od usług i produktów monopolistów z USA. Diabeł jednak tkwi w szczegółach.

You Want to Visit the UK? You Better Have a Google Play or App Store Account

You Want to Visit the UK? You Better Have a Google Play or App Store Account | Philip Heltweg

New immigration rules for the UK are being enforced starting February 2026. This means citizens of 85 additional countries (including the USA and European countries) will need an Electronic Travel Authorisation (ETA) to visit, even for tourism. Luckily, you can apply (and pay) digitally. Unfortunately, the government very much would prefer you to do so using the official app.

Dissecting the CPU-memory relationship in garbage collection (OpenJDK 26)

Link: norlinder.nu/posts/GC-Cost-CPU
Discussion: news.ycombinator.com/item?id=4

OpenJDK 26 introduces new telemetry to quantify the CPU-memory trade-off in garbage collection.

Dissecting the CPU-Memory Relationship in Garbage Collection

Every time you configure a Java application’s heap size, you are essentially making a trade-off: spending more on infrastructure to improve performance metrics such as throughput or latency. Historically, this trade-off was visible when an undersized heap triggered long pauses, signaling a need for more resources. With modern collectors, however, pause duration and computational effort have become decoupled. This creates an operational blind spot: dashboards may show excellent response times, while the collector silently consumes excess compute capacity to compensate for a constrained heap. To address this, it is essential to look beyond GC pauses and examine overall efficiency using new tools. This article, therefore, analyzes why we need additional metrics for infrastructure efficiency and introduces the new Java API for GC CPU in OpenJDK 26, which empowers engineers and researchers to quantify the collector’s CPU overhead and make informed memory-CPU trade-off decisions.

i checked up on OsmAnd and apparently they're doing some pretty advanced stuff for offline route calculation now! beyond A* osmand.net/blog/fast-routing/

OsmAnd's Faster Offline Navigation | OsmAnd

Offline navigation is a lifeline for travelers, adventurers, and everyday commuters. We demand speed, accuracy, and the flexibility to tailor routes to our specific needs. For years, OsmAnd has championed powerful, feature-rich offline maps that fit in your pocket. But as maps grew more detailed and user demands for complex routing increased, our trusty A algorithm, despite its flexibility, started hitting a performance wall. How could we deliver a 100x speed boost without bloating map sizes or sacrificing the deep customization our users love?

It’s a pretty esoteric thing, but I had to call it out because it’s so nice to see small things get fixed. The mysterious JamieQ saves the day yet again.

drove from my place in melbourne to my friends' place in sydney with no gmaps no gps, just handwritten pre-planned directions for the arrival into sydney. All went to plan, on time and no wrong turns! Feeling pretty proud of that

I see that Mastodon got a mention on The Guardian's guide to leaving big tech: "German-developed Mastodon, whose feeds boast considerably less hate, misinformation, bot-generated content and AI slop" theguardian.com/technology/202

Leave big tech behind! How to replace Amazon, Google, X, Meta, Apple – and more

A handful of companies monopolise the web, with unprecedented access to our data. But there are many more ethical – and often distinctively European – alternatives
