How does a code completion tool work? What is an Abstract Syntax Tree, and how is it created in Python? How does an AST help you write programs and projects that inspect and modify your Python code? This week on the show, Meredydd Luff, co-founder of Anvil, shares his PyCon talk, "Building a Python Code Completer."

Imagine your job is to personalize search results on an e-commerce site for returning customers, classify the presence or absence of pedestrians in street photos, or develop an app that translates languages. In all of these cases, a basic ingredient is a dataset of annotations provided by a human. For any company seeking to personalize experience for its customers, combining human computation with algorithmic computation is essential. T....

Robin Rendle quoting Neil Gaiman, who is quoting G.K. Chesterton: Fairy tales, as G.K. Chesterton once said, are more than true. Not because they tell us that dragons exist, but because they tell us that dragons can be defeated. I read somewhere that he based the Gilbert character from The Sandman on Chesterton, so it’s no surprise to find Gaiman quoting Chesterton in Smoke and Mirrors . Wanting to find the work in which the ..

Unfortunately not what this post is about. Credit: katiebcartoons.com I came across Roaring bitmaps when I learned about this fun hack to do retention analyses at scale with bitmaps. Using Roaring bitmaps instead of traditional bitmaps in that application reduced memory usage from ~125GB to 300MB, an impressive 99.8% savings. But… how? You can learn about Roaring bitmaps over two research papers: This one proposes the data structure. This o..

On Windows, NVDA is more capable but Narrator + Edge is more secure. Narrator and Edge were designed to work without giving Narrator access to the content process, using the UI Automation API (UIA). Edge’s UIA was merged into upstream Chromium but it was only enabled in Edge. Matt Campbell wrote about it on the orange site in January 2021 ; I don’t know if the situation has changed since then. Try both. If Narrator works for you I’d stic..

No need for expensive Tableau subscriptions. Ditch Microsoft Excel. Just use native PostgreSQL to quickly visualise your data! Here’s an idea I had for a while. As you may know, jOOQ can produce fancy charts from your jOOQ results. But that requires you use jOOQ, and you may not be using jOOQ, because you’re not … Continue reading How to Plot an ASCII Bar Chart with SQL →

Client-side storage (cookies, cache, etc.) is one of many things worth disabling during site testing. The Tor Browser’s “safest” level blocks SVG, remote fonts, JS, and other features; many textual browsers don’t support anything besides a subset of (X)HTML. Most non-mainstream search engines are similar. Personally, I try to keep sites curlable . It should be possible to use a plain curl URL command to get all the necessary markup, co..

This post announces the preprint on quantile absolute deviation as a flexible robust scale estimator. Pragmastat recommends Spread — the Shamos estimator — as a more efficient robust scale alternative with a 29% breakdown point. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat I have just published a preprint of a paper ‘Quantile absolute deviation’.

In one of the previous posts , I suggested a new measure of dispersion called the standard quantile absolute deviation around the median ($\operatorname{SQAD}$) which can be used as an alternative to the median absolute deviation ($\operatorname{MAD}$) as a consistent estimator for the standard deviation under normality. The Gaussian efficiency of $\operatorname{SQAD}$ is $54\%$ (comparing to $37\%$ for MAD), and its breakdown point is $....

Open Culture shared a “jaw-dropping visualization of John Coltrane’s ‘Giant Steps’ solo.” Indeed, it is stunning, beautiful and valuable. A visualization like this makes music much more accessible. Quoting Open Culture: Coltrane’s complexity is daunting for the most accomplished musicians. How much more so for non-musicians? It can seem like “you need a doctorate of music to go anywhere near his recordings,” Nicholson writes. ..
