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].....

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. Recently, in the main Techlore room, mazerfaker, DriftNotSkid and I were having some fun and joking around a bit after I said "Tell me something new" in reaction to a screenshot of one of those fingerprint testing sites stating "Your browser has a uni..

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..

Tests should be correct by inspection Tests require a different approach than normal code. We don't have tests for tests, so tests need to be correct by inspection -- and the main technique to achieve this is to get rid of the generality of the production code, and exercise only very narrow and specific scenarios.

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.

Ever had your old, trusty Python virtual environment fail on you? I sure did. Sometimes, when I activate or switch between virtual environments, I get the following error: $ workon eve dyld: Library not loaded: @executable_path/../.Python I never really took the time to look into it. When this happens, because I am in a rush (and because I am a lazy old fart), I shrug it off, recreate the virtual environment on the spot, and get back to ..

CSS-in-JS is a relatively new and a very contradictory way of writing CSS. On the one hand, it tries to overcome the limitations of traditional CSS to make it more reusable, especially when it comes to styling components. On the other hand, it’s different from traditional CSS and has it’s own disadvantages. There is no single CSS-in-JS library, there is even no sight of a clear winner in this race. However, all CSS-in-JS implementations hav..
