Do you feel like you understand how Python works under the hood? What is syntactic sugar, and how much of it should be in Python? This week on the show, we have Brett Cannon. Brett is a Python core developer and he's been working on a series of articles where he is unraveling the syntax of Python. His series is a fantastic resource for those wanting to learn how Python is structured and works at its core.

What music do you listen to while programming? 1 For me, it’s usually jazz, classical, electronic, lots of it, or nothing. There are some specialized websites and podcasts I sometimes recur to, like [Music for Programming][1]. Several Spotify playlists I dig a lot, [Every Day I’m Nerdin’][2] being one of them. What can I say? I am musically omnivore. However, I recently discovered something different: the [Field Recordings podcast][3].....

Despite its simplicity, classical mechanics is not taught well in the typical physics curriculum. This is unfortunate because the general philosophy of constructing Lagrangians based on symmetries underlies all of modern physics. In this article, I explain basic Lagrangian mechanics in a systematic way starting from fundamental physical principles. It basically follows Landau and Lifshitz … Continue reading "Fundamentals of classical mech..

So, you’re a product manager, and following your success in launching a new product last year, you’ve been promoted to product manager of your organization's flagship product ‘20-Year-Old-Monolith-Beast’, just as the organization embarks on a much-needed modernization initiative. There’s a bit of a smell around the transformation, and many of your stakeholders are pushing for an MVP (minimum viable product). They’ve heard that’s the best pr..

Update: The joke has worn off, there are more interesting and elaborate parody religions, such as Pastafarianism, and so on… The link mentioned is dead and the menu entry has been removed.

Last fall, we made the decision to launch a Community Outreach Internship Program at Snyk. Like many across the globe, we at Snyk were troubled by how the economic impacts of covid-19 are disproportionately affecting women and underrepresented minorities, and wanted to ensure that Snyk was playing a role in being a part of the solution.

Leaflet-Hexbins is a powerful tool to aggregate data and visualize it quickly on a map. It can size the hexbin radius based on a feature values. But what if we used HyperLogLog data to preserve user-privacy? This post will provide a convenient way to quickly perform on-the-fly HyperLogLog unions for leaflet-hexbins. No more backend-constraint for HyperLogLog There are many HyperLogLog implementations out there but few work as well as pos..

Feedback is one of the most importante things when you are creating a product (probably the most important one!), so it should be easy for users to give feedback. In this post we’ll see how to implement a feedback button easily. This exact code is what I’m using at drwn.io , a little project I’m working on with a friend. The button does the following: after you use it, it will change its text to “Thank you!”, then it will fade out we wil..

Querying Postgres with Python Fastapi Backend and Leaflet & Geoman Fronted - Applying Geometry Filters How to query a database with a user-defined geometry drawn on a Leaflet frontend? A very common use case for map applications are custom filters. Either thematic, temporal or value-based filters play a significant role but probably in a geographical context the most dominant one might be spatial filtering. In this blog post, I describe a..

So you want to add a diagnostic setting to your Azure storage account via Terraform and you pass the storage account ID to target_resource_id only to get the following error: Status=400 Code=“BadRequest” Message=“Category ‘StorageWrite’ is not supported.” Here is the fix, the diagnostic target resource actually needs to be a sub-resource of the storage account, the ID for that is constructed as: /blobServices/default/ Using ..

Panics in Rust are normally isolated to the thread that caused them, and are sometimes recoverable. This post introduces panik-rs, a crate to make panics on all threads fatal (to the application!) and prevent them from being silently swallowed.

This post derives finite-sample bias-correction factors for MAD to make it a consistent estimator of the standard deviation. Pragmastat recommends Spread — the Shamos estimator — as a more efficient robust scale alternative that does not require such corrections. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat The median absolute deviation ($\textrm{MAD}$) is a robus....

After almost a decade, we decided to rebuild our in-house Business Intelligence web application to better support the organization. It is always challenging to replace software with a long history and a high degree of complexity. Nevertheless, we successfully completed the project because we fundamentally challenged and re-thought all aspects of the project.
