At some point most of us will go insane when #AI will be down for an hour like #claude right now.

A very easy to read article about discovery of CVE-2026-16723 (RCE in fastjson) and some details of how #Java Class Loaders and Resource Handling work. #cybersecurity fearsoff.org/research/fas...

FastJson 1.2.83 Remote Code Execution
Turning fastjson 1.2.83 into remote code execution with AutoType off and no gadget on the classpath: an SSRF inside checkAutoType, the @JSONType bypass, and a /proc/self/fd trick that carries it from ...

Reolink именно модели без аккумуляторов. Распознавание людей и животных работает шикарно, пуш прилетает за секунду. В Home Assistant платиновая интеграция. Причём есть очень светочувствительные модели. А вот датчики движения выбесили в своё время.

In their post about UDP introduction, DuckDNS also mentioned, among other things, adopting Java 21 virtual threads. Of course it's an exception to a rule and one wouldn't expect it from most companies, but it's pleasant to get such updates with some technical details. #java www.duckdns.org/udp.jsp

Faster UDP under load, and cleaner addresses

Railway companies such as @deutschebahn.com and @ns.nl having issues with boundary values. They don't look with favor on short E-mail addresses (1 char before '@'). While DB have completely banned such addresses, Dutch railways applied a weird filler to the mask. What's wrong with that really?
Exactly 100 asterisks filler to mask a short E-mail address

Someone tried to steal my (absolutely unknown) domain and my registrar account exactly when it was about to expire. The attempt was pretty good, so I decided the very first post on my blog will be about it. Here it is: belinski.dev/blog/2026-05... #security #infosec #phishing

I got an email pretending to be Netcup telling me my domain expired and deactivated. Of course it wasn't.

Cat-Supervised #Testing (CST) is a process in which Felis Catus proximity increases environmental coziness and perceived cuteness. May accidentally lead to Cat-Driven #Development (CDD), e.g. when a laptop is left unlocked.
