What did you do at work today? How about last week? I spent a couple of days in quarterly business reviews, and wrapped up yearly planning activities for AWS Data Exchange and AWS Marketplace. I also added some unit tests to a project that I am onboarding into.
In this article we take performance of the SSD300 model even further, leaving Python behind and moving towards true production deployment technologies: TorchScript, TensorRT and DeepStream. We also identify and understand several limitations in Nvidia’s DeepStream framework, and then remove them by modifying how the…
Diesel (http://diesel.rs) is an ORM (Object-relational mapper) and Query Builder written in Rust. It supports Postgresql, Mysql and SQLite…
Cyrille Rossant's small ray-tracer is an nice self-contained Python program (using NumPy) that renders this 400×300 image in about 15 seconds on a fast PC:
Learn about rate limiting algorithms with interactive apps, including Token Bucket, Leaky Bucket, Fixed Window, and Sliding Window methods
I imported the entire Linux kernel git history into pgit's PostgreSQL-backed storage. 1,428,882 commits, 24.4 million file versions, 20 years of development. Here's what the kernel looks like when you can just ask.
Meteor, say hello to cross-platform native app-development. Qt, say hello to a modern, reactive web back-end. TL;DR You can write a nativ...
TL;DR I wrote a .NET library that can compile C/C++ code into a byte code that it can also interpret. It is used in my app iCircuit to simulate Arduinos. You can use it yourself with the nuget package CLanguage.
UPDATE July 2021: 6 years later, there’s a game and also an updated explainer video .
I adore Nerves. I recently joined the core team. And I'll be doing my best to help people get along with this lovely way to co-mingle hardware and massively concurrent reliable software.
Order by in aggregates, better string concatenation, and thorough date formatting.
Perhaps the most interesting part of the open RISC-V instruction set architecture (ISA) is the vector extension (RISC-V "V"). In contrast to the average single-instruction multipe-data (SIMD) instruction set, RISC-V vector instructions are vector length agnostic (VLA). Thus, a RISC-V "V" CPU is flexible in choosing a…
PostgreSQL is currently entering its final commit fest. While its still going, which means there could still be more great features to come, we can start to take a look at what you can expect from it now. This release seems to bring a lot of minor increments versus some bigger highlights of previous ones. At the same…
I first ran into Forth about 20 years ago when reading a book about designing embedded hardware . The reason I got the book back then was to actually learn more about the HW aspects, so having skimmed the Forth chapter I just registered an "oh, this is neat" mental note and moved on with my life. Over the last two…
Implementing the famous donut.c animation in actual silicon using CORDIC and ray marching
Unix is a bestiary of ad hoc databases: comma-, colon-, tab- and space-separated tables. Think of /etc/* or /var/log/* , or of columnar commands.
I wrote up my experience using Python to process data from a shared Google Sheets spreadsheet
Many software engineers use database indexes every day, but few of us really understand how they work. In this post I’ll explain: How indexing works in Postgres using B-Trees What B-Trees are Why they are a good fit for this problem Indexes in Postgres Postgres actually offers 4 different kinds of indexes for…
Hi, I'm Ariel (she/her), a newly-minted member of the Swift team at Apple ! Previously, I helped lead the Luau team at Roblox where my efforts primarily focused on the design and implementation of Luau 's type system. I also led the creation of Lute to support using Luau both to build developer tooling, and as a…
In 2023, we launched an AI-powered Chief of Staff for engineering leaders—an assistant that unified information across team tools and tracked critical project developments. Within a year, we attrac...
Poking at the geometry of an image model's feature space.
Since Version 10.10 (Yosemite), OS X contains Hypervisor.framework, which provides a thin user mode abstraction of the Intel VT features. It enables apps to use virtualization without the need of a kernel extension (KEXT) – which makes them compatible with the OS X App Store guidelines.
I used to have trouble keeping track of my files. I often couldn’t remember whether I saved a file on my desktop, laptop, or phone, or if it was floating around in the cloud somewhere. Plus, with certain information, like passwords and bitcoin keys, I didn’t feel comfortable just sending that in an email to myself in…
In the past I have presented simplified descriptions of D3 ’s selections, providing only enough detail to get started. This article takes a more comprehensive approach; rather than saying how to use selections , I will explain how selections are implemented . This may take longer to read, but it should dispel any…
People complain about Rust syntax. I think that most of the time when people think they have an issue with Rust's syntax, they actually object to Rust's semantics. In this slightly whimsical post, I'll try to disentangle the two.
