This post compares the efficiency of the Mean, Sample Median, and Hodges–Lehmann estimator under heavy-tailed distributions. In Pragmastat, the Hodges–Lehmann approach is Center for location and Spread for scale — both with a 29% breakdown point and high efficiency. pragmastat.dev github.com/AndreyAkinshin/pragmastat In the previous post , I shared some thoughts on how to evaluate the statistical efficiency of estimators un..

Part one With it being a decade since I was last at school, you’d think I’d be over it. Sometimes I think I am. And then I dream. I’m suddenly back at school, or a face I had forgotten comes back to me, and it all comes back: the powerlessness, humiliation, the anger that someone could hurt me so much for kicks – and finally the horror that I’m unable to stop them. Everything comes back. Not even waking up removes the fear, as I spen....

This June marked 10 years since I left school. I was the weird kid. I don’t know if I was innately weird, or if years of bullying turned me that way. Either way growing up wasn’t fun. When I was 7 years old my family had to move across the country, I landed in a new school at the point where friendships and social dynamics were ironed out – if it wasn’t apparent that there was no room for me, my new classmates would make sure I knew. ....

The Cow and Chicken are journeying through the countryside and see a diner with a sign that reads "Steak and Eggs". The chicken nudges the cow and cackles delightfully: "Look! Look, Cow!! We're famous!!!". Whereupon, the cow looks at the same sign and snorts derisively: you're involved! I am committed!!

This morning, still a bit sleepy, morning coffee in hand, I came across a Hacker News post about Beg Bounties . Intrigued by the title, having heard about Bug Bounties before, I learned about its next logical conclusion and the people that “randomly” discover security vulnerabilities and then expect to be paid for their “ethical disclosure”. Putting this aside as a Today I Learned kind of thing, I logged into my work email, only to b..

Macros are tricky beasts. Most languages—if they have macros at all—usually include a huge “here there be dragons” warning to warn curious would-be macro programmers of the dangers that lurk ahead. What is it about macros that makes them so dangerous and unwieldy? That’s difficult to answer in general: there are many different macro systems with varying degrees of ease-of-use. Moreover, making macros easy to use safely is an open area of ....

Hi, Mir kribbelte es in den Fingern. Direkt zu Beginn von Thorben Janssens Session “Das große Java Persistence Q&A”. Die erste Frage war (sinngemäß): “Im vorherigen Talk (etwas mit JPA) wurde gesagt man solle an jeden Test @Transactional schreiben. Dadurch werden die Daten nach dem Test automatisch zurückgerollt. Wir haben das diskutiert und sind uns uneinig. Was ist deine Empfehlung?” Thorbens Antwort machte mich nervös. Er ..

There are a number of blogs and serials that I really enjoy reading and (where available), I've tended to subscribe to their RSS feeds using Nextcloud News . What I've noticed though, is that, amongst everything else I do on my phone, the new article notifications do tend to get lost. The result is that I quite often don't notice that a new post has been published unless I happen to see someone else toot it into the fediverse (for exampl....

Following are some shortcuts that I believe all desktop users should be familiar with. It is not a complete list by any means, and does not include virtual desktop or app pinning shortcuts as I felt those were beyond the scope of common desktop shortcuts. If you feel I omitted a common shortcut, email me ( jason.eckert@trios.com ) and I’ll add it to the list! 1. Windows shortcuts The Windows (⊞) key on your keyboard has the Windows logo p..

I recently redid the DNS on my home network, moving from dnsmasq to Unbound and NSD . Unbound acts as the DNS server the network uses, and Unbound hosts losts local zones for my search domains. For reasons, this is really across two sites: our home, and a barn we own a few miles away. Because I am a dork, I have things at both sites :-) My network controller has a built in DNS server which assigns a local domain, a la brians-laptop.l....

That one boring Saturday I wanted to learn something more about agents and thought it would be a really cool idea to “unfinalize” java.lang.String. I started working on the project, developed simple transformer: if (name.equals("java/lang/String")) { ClassPool classPool = ClassPool.getDefault(); final CtClass ctClass; try { ctClass = classPool.get(name.replace("/", ".")); } catch (NotFoundException e) { throw new RuntimeException(e); } int ..

A Java project with published container image that contains intentionally leaky native code to observe symptoms of a memory leak in Java in podman/docker or Kubernetes. Native code intentionally “leaks” provided number of megabytes in a loop. The project runs by default with -XX:NativeMemoryTracking=summary enabled. I wanted to observe how JVM will report native memory, crash and what pod and JVM metrics will look like. Java doesn’t allocat..

I cannot let 2023 go past without writing anything given it is 20 years of this blog, but an update to Hugo broke things, and getting it to work was just annoying.

Along the way I took a moment to add all the posts from my original blosxom based blog to the archive , which makes me happy. Really, I want to pos..

Envoy Proxy is a well known proxy load balancer offering HTTP, gRPC, TCP, customizable with Lua, Go, WASM … It’s often the core component used to build gateways/proxies for Kubernetes. For example Istio is using it as a proxy load balancer for ingresses but also as a sidecar to create a “mesh network”. Envoy Gateway is a more recent project to manage Envoy proxies inside Kubernetes, it is meant to be a common foundation to build on top of i..
