In the previous post , we have obtained a nice quantile estimator. To be specific, we considered a trimmed modification of the Harrell-Davis quantile estimator based on the highest density interval of the given size. The interval size is a parameter that controls the trade-off between statistical efficiency and robustness. While it’s nice to have the ability to control this trade-off, there is also a need for the default value, which could..

UPDATE 2025-05-19 Somewhat un-suprisingly AWS has closed the loophole that I was exploiting for this https://aws.amazon.com/service-terms/#30._AWS_Lambda and as such compiling data into your lambda for “free” storage is no longer allowed. As such bonzamate.com.au in its current iteration has been shut down. Watch this space however! I have some ideas on how to bring it back, albeit in a different form. TL/DR I wrote an Australian s..

Comments Balance Learning how to ride a bike requires you to balance in new ways. Riding a bike on a tight rope requires similar balance, and I can only image the perceived risks of failure makes it exponentially harder to focus. Trying anything new will require some sort of balance. Physical, mental, time management, relationships all create a balance in our lives that can easily topple due to unexpected illnesses, changes in priority, ..

I’ve spent some time the last week optimizing how the search engine identifies appropriate search results, putting far more consideration into where and how the search terms appear in the page when determining the order they are presented. Search-result relevance is a pretty difficult problem, but I do think the changes has brought the search engine in a very good direction. A bit simplified, I’m building tiered indices, ranging from

Update 2025-12-11 : There is now a follow up article (4 years later) . TL;DR YAGNI , unless you’re working in a big company with federated front-ends or GraphQL. It’s popular in web dev nowadays to build a backend that serves JSON , and a frontend that renders the app. This is fine. I’m not the biggest fan, but it’s really okay. Except it’s not okay if you think that your backend needs to be designed like a generic public API . Th....

Introduction You are about to visit Boston, and would like to taste some good food. You ask your friend who lives there what are good places to eat. They reply with “Everything is good, you can’t go wrong”. Which makes you think, maybe I should check where not to eat. The data geek in you arises, and you find out that the city of Boson has a dataset of food violations . You download it and decide to have a look.

Comments One more feature It’s difficult with software to know when to stop and release what you have. There’s always one more feature to create and one more bug to squash. Putting out software you know has bugs or doesn’t do everything you want is anxiety inducing but also freeing because it can only get better from here.

In this article, I argue that we can apply game theory to explain and control the behaviors that dominate in an online community. Not only can game theory explain why misinformation and abuse are so common in social platforms, it can be used to design social platforms that will be filled with honest, informed, civil, and behavior.

Comments Company presentations and movie magic I often watch conference talks from companies that appear to be complete internal products, but behind the scenes are more like the blackbird car in the gif above. Companies have high performance, purpose built solutions they create and then present them as the answer to everyone’s problem. This isn’t always a negative thing. You should be aware that their Ferrari may not have a windshield or ..

I recently came across a really fascinating video – https://www.youtube.com/watch?v=tYFLze9VwB0 where they make use of a micro laser projector to generate a speckle pattern on a surface and then photograph it with a DSLR. They then simply touch a surface with their hand/finger and then take a photo of the speckle pattern again after the […]

Hey there, thought I'd write this one. Only one here who hasn't written anything yet, after all. It seems to get hard to get more creative titles with this sort of post, so that one's what we went with. Anyway. Nitter We gave this one up for now. It doesn't work on ARM due to being written in Nim, so that's it, I guess. We might set it up on another machine and then proxy or something, dunno. Veloren We have a server for that now, runni..

View of Snow Lake as you descend the ridge. Summary Snow Lake is incredibly popular, and for good reason. The hike is beautiful from start to finish, especially with the low lying blankets of mist that roll through the trees and across the lake. It’s barely an hour’s drive from Seattle, yet feels like remote, unspoilt wilderness.

Comments The weight of nothing Sometimes we make decisions in software and design that appear to have no impact on what we’re building. After many years of unchecked decisions we may find our systems breaking from a million — seemingly weightless — snowflakes. Future of open source Open source is changing and so are the people and communities. What started as free software stored in a drawer back when people used to share computers has e..

Humidifiers and I have a several-year-long history, in which I’ve considered countless humidifiers and tried…a couple. My problem with humidifiers is that I’m lazy . I do not want to scrub them clean. I don’t want to even wipe them after each refill. I don’t want to find yellow goo under the tank that I have to clean by hand.

Comments HTML There were some conversations on Twitter this past weekend that HTML is not a programming language. I don’t care about semantics, but I DO care to recognize people that write HTML as developers. My first full-time job I wrote code to solve problems even though I didn’t have “developer” in my title. I automated a job that used to take 3 weeks down to 3 hours with the code I wrote. It just so happened that my IDE was Excel.
