In the fall of 2016, I was a Teaching Fellow (Harvard's version of TA) for the graduate class on "Advanced Topics in Data Science (CS209/109)" at Harvard University. I was in-charge of designing the class project given to the students, and this tutorial has been built on top of the project I designed for the class.
SIMD is a powerful performance technique, and is especially valuable in signal and image processing applications. I will be using it very extensively in my synthesizer, and also it’s increasingly used in xi-editor to optimize string comparisons and similar primitives.
This blog site has been archived. Go to react.dev/blog to see the recent posts. Today we’re releasing React 16.6 with a few new convenient features. A form of PureComponent/shouldComponentUpdate for function components, a way to do code splitting using Suspense and an easier way to consume Context from class…
When WebAssembly was first shipped it was an MVP which, while minimal, has spawned a huge number of exciting projects which work today across all major browsers. Rust has capitalized on the wasm MVP’s success as well with tools like wasm-bindgen and wasm-pack by making the MVP feel less minimal. WebAssembly is yet…
Array and hash table are probably the most important data structures. Some programming languages such as Perl, Lua and Javascript, almost build the language core on top of the two data structures. …
Rust can be difficult to learn and frustrating, but its also the most exciting thing in software development in a long time. Learn more by reading our blog.
People have a misconception—they think that the WebAssembly that landed in browsers back in 2017—is the final version. In fact, we still have many use cases to unlock, from heavy-weight ...
In this post, we set up the programmable interrupt controller to correctly forward hardware interrupts to the CPU. To handle these interrupts, we add …
Agile Software Development may be mainstream, but much of what's done is faux-agile, and we need to push back.
When receiving bytes from the network, we often assume that they are unicode strings, encoded using something called UTF-8. Sadly, not all streams of bytes are valid UTF-8. So we need to check the strings. It is probably a good idea to optimize this problem as much as possible. In earlier work, we showed that ……
Aftermath of how I moved stars to a great project from an simple project with undeserved stars
I recently learned that in the mid 90s in Japan, the Super Nintendo had a peripheral called a Satellaview, which was a satellite modem that would receive data broadcasts from Nintendo.
Let's talk about when it might be a good or bad idea to start using microservices. SPOILER ALERT: it's not the same for every project.
We need programming, but do we need the program?
All C++ interview questions have everything you need on live interview – explanation, possible right/wrong answers, following questions.
Ever since version 1.1, Opus has been able to automatically detect whether its input is speech or music, and choose the optimal encoding mode accordingly. The original speech/music detector was based on a simple (non-recurrent) neural network, followed by an HMM-based layer to combine the neural network results over…
Everything you need to know today about Python Packaging: PEPs 517/518, pyproject.toml, Pipenv, setuptools, and—of course—pip.
In this post we’ll explore Haskell’s kind system, the similarities between types and kinds, and show how these can be leveraged to write safer and more reusable code.
Stripe + Twilio <Pay> lets businesses easily and securely accept payments over the phone.
As a developer, you have the power to change the world! You can write programs that enable new technologies. For instance, develop software to find an earlier diagnosis of diseases. But that’s not the only way. You might do it indirectly by creating projects that make people more productive and help them free up time…
I really like decision tables but they’ve fallen out of common knowledge. Let’s fix that. A decision table is a means of concisely representing branching and conditional computations. In the most basic form, you have some columns that represent the “inputs” as booleans and some columns that represent outputs and…
Google Cloud is announcing a new Go 1.11 runtime for App Engine, with fewer limits on app structure.
Complexity is the most important challenge in software development. So it is important to always strive to eliminate complexity. But sometimes we worship complexity - and that can make complexity problems unsolvable.
Windows has long had a reputation for slow file operations and slow process creation. Have you ever wanted to make these operations even slower? This weeks’ blog post covers a technique you can use…
Hitting the limit for maximum allowed connections is a common operational problem in Postgres. Here we look at a few techniques for managing connections and making efficient use of those that are available.
A guide to how we built the CKEditor 5 architecture for collaborative editing from the ground up, by extending Operational Transformation concepts.
