Peter Firmstone continues his series on #Security on the #JVM. Today: what the guarantees cost. Nobody runs a SecurityManager in production because it dies under load. DirtyChai makes a permission check lock-free and cache-friendly on virtual threads; JGDMS grows a fleet by starting 1 more process.

blog.frankel.chSecurity Baked Into the JVM: DirtyChai scales vertically, JGDMS scales horizontallyNobody runs a SecurityManager in production. The usual reason given is that it does not survive a load test, and every guarantee in this series was bought with a check: a constraint on each call, an a...

>Pipeline test slimmed from ~700 to ~220 lines While improving the line and the mutation #codecoverage. That's what I like to read at the end of a #refactoring session. Refactoring production code is good, but don't forget tests! Tests are the unloved children of developers.

To build a #maps application, you pick a tile provider such as #Google or #Mapbox, or a self-hosted stack like #GeoServer or #Martin. @stefanofago.bsky.social asked himself if a different approach was possible. He found #PMTiles that removes the tile server. Read on!

Until we understand what it means that russia is waging a Vernichtungskrieg—a war of extermination—in Ukraine, not only will we have failed to grasp the essence of russia’s war and its strategy today and tomorrow, but we Europeans will remain unable to make the necessary decision.

Next level phishing: "My name is John Scognamiglio, and I serve as Editor-in-Chief at Kensington Publishing. I recently came across Integration Testing from the Trenches [...]" They target using data from my website. Too bad they use an aol.com address in 2026.

Le consulat général russe de Bonn "aurait pu" être utilisé comme centre d'activités de renseignement et de soutien aux opérations hybrides en UE. Selon des sources de Bruxelles citées par Bild, 15 à 20 agents du SVR, du FSB et du GRU, se faisant passer pour des diplomates. Nooonnn ?! Alors, Paris ?

Trump is a filthy bastard. His collusion with russia amounts to high treason. While Moscow continues to escalate its massacres of Ukrainians, Trump is offering criminals money. It's a strong incentive for the Ukrainians to bomb russian refineries even more—the Europeans must help them decisively.
