Update: the latest version of this approach is presented in [[partitioning-heaps-quantile-estimator3]]. In one of the previous posts, I have discussed the Hardle-Steiger method. This algorithm allows estimating the moving median using $O(L)$ memory and $O(log(L))$ element processing complexity (where $L$ is the window size). Also, I have shown how to adapt this approach to estimate any moving quantile. In this post, I’m going to ....

I have found myself procrastinating a lot in my free time. This was especially noticeable to me toward the end of my Christmas vacation, and yesterday - the first Saturday since starting work again.

In my previous two posts, I talked about Self as the language, and the system which allows it to serialize objects into text format. Now let’s talk about another big part of Self, which is the programming environment and the UI toolkit that it is created from: Morphic.

In my previous post , I talked about Self and gave a general tour of the language and the programming environment. I mentioned that Self was an image-based programming language. Of course, if you want to develop a Self application with multiple people, an image is not suitable for collaborating (except in real-time – we’ll come back to that in a later post). Your Self image contains everything in your programming environment (provided you ..

What is it like to design a Python library for three different audiences? This week on the show, we have Nir Aides, creator of Jupylet. His new library is designed for deep reinforcement learning researchers, musicians interested in live music coding, and kids interested in learning to program. Everything is designed to run inside of a Jupyter notebook.

Hey there. This is the first post I will be making here, and I wanted to give a tour of Self before making posts about my current implementation, mySelf. Throughout this post, I will be showing examples from the regular implementation of the Self programming environment, available here . What is Self? To quote the Self language homepage : Self is a prototype-based dynamic object-oriented programming language, environment, and virt..

Black Mirror: Bandersnatch (2018) is an interactive film in which viewers are periodically asked to make decisions for the main character Stefan Butler, the decisions then result in different scenes, and paths through the film, resulting in a branching path to a variety of endings. Think “choose-your-own-adventure”, but in interactive video. Since television viewers are conditioned to be passive spectators, the film included a tutorial e....

I finished reading Erebus: The Story of a Ship by Michael Palin, an excellent book on the dramatic adventures of the HMS Erebus with her sister ship, the HMS Terror, first in James Clark Ross’s Antarctic expedition of 1839-43, and then during Franklin’s ill-fated Arctic expedition in search of the Northwest Passage. I knew Michael Palin as a member of the Monty Python comedy group. As it turns out, since 1980, he has also made many travel..

Here’s a little SQL query that lists all Oracle wait events where Oracle kernel developers have added additional “human readable” descriptions. Since the original wait event names shouldn’t be changed for compatibility with existing tools, then a new column DISPLAY_NAME was added: SQL> SELECT name, display_name FROM v$event_name WHERE name != display_name; NAME DISPLAY_NAME ----------------------------------------- ----------------------....

Introduction If you can write a for-loop, you can do statistics. - Jake Vanderplas A lot of developers shy away from problems which involve statistics or probability. Which is shameful since in today’s data-rich environment, you can gain a lot of insights from data. In this blog post, I’ll show you how to write a simulation tool which requires no knowledge in statistics or probability. Simulations are easy to write and can be a very ..

Keeping things separate for the two type of encryption, an easy and less secure way: S/MIME, and the more robust and secure PGP.

This is an early attempt at blender from 2021. It started with a drawing that I loved. I’ve poked around Google Images but so far I haven’t found the original artist. I quickly modeled a few things, trying to create a more 3d look rather than sticking with the more stylized look. I’m not sure if this was ultimately the right choice. The moon was a little tricky to get right and I haven’t nailed the look of low light.

Figure 1. Asciidoc. I’ve been using reStructuredText for writing on this blog, because it has lots of built-in features that markdown doesn’t. However, reStructuredText’s actual syntax is a bit… fiddly - particularly its non-atx headings, too many things relying on lining up white space, etc… If I don’t use it for a bit, I have to look up or copy & paste all the advanced syntax. I’d prefer to use AsciiDoc, as it has all the extra....

Preface This is a tale of the intersection between thermal physics, cosmology, and a tiny amount of computer science to answer a seemingly innocuous question: “How strong does a password need to be for it to be physically impossible to brute-force, ever?” TLDR at the bottom. Note: this post contains equations. Since none of the equations were long or complex, I decided to just write them out in code blocks instead of using images ....

MP² quantile estimator: estimating the moving median without storing values

In one of the previous posts, I described the P² quantile estimator. It allows estimating quantiles on a stream of numbers without storing them. Such sequential (streaming/online) quantile estimators are useful in software telemetry because they help to evaluate the median and other distribution quantiles without a noticeable memory footprint. After the publication, I got a lot of questions about moving sequential quantile estimators.....

The First 90 Days” by Michael D. Watkins is a book on leadership transition that I had delivered to me from my new manager at the role I just took on at a new company. I read the book ahead of starting last month but finally got around to sitting down and writing out my summary. The book provides a comprehensive framework for making a successful transition, with practical advice and tips that are applicable to any industry or organization.
