This article demonstrates how to configure TLS/SSL certificates with the Ingress controller in Kubernetes. We'll set up an NGINX Ingress controller, create a self-signed SSL/TLS certificate, create the necessary rules to link the SSL/TLS certificate to the controller, and hook it up to a Kubernetes sample app service.

Computations that differentiate, debug, and document themselves

One of the problems we wrestle with at Jane Street is how to understand and manage the costs associated with the positions we hold: things like margin, financing costs, market risk, regulatory capital requirements, and so on. To that end, we’ve built systems that estimate these costs and propose ways to reduce them. Essentially, this is a numerical optimization problem.

I had a friend ask me what continuations are, and why they’re useful. There’s a ton of literature about continuations; this is just a simple example meant to showcase something small and hopefully grokkable.

A self-attention block depicted as a neural network. In this post I will describe the attention mechanism, commonly used in transformers, a popular neural language architecture. Most of the most well-known large language models of late are based on the transformer architecture. Attention was first described in Attention is All You Need by Vaswani et al. What is attention? At a high level, attention is a mechanism for neural networks..

I just read a reddit post. It was about someone’s colleague who writes complex code over simple code. Unnecessarily I should add. At least as per the post. But that is when it struck me. The reason for writing simple code is the same as it is for simple writing. One of the best advices I got about writing was to write simple. You write simple and consumable sentences instead of using fancy words and complex sentences. This helps more read....

we can ship production code with Clojure. A strange bit of grumbling I hear from developers directs their angst toward not having "compile time type checking errors"

Problem: Compute the product of two polynomials efficiently.

I spent the last week working from Tbilisi, Georgia and want to share what I experienced and where I could work and couldn’t. It’s not very easy to find a good place to work sadly. The friendliness from people working at coffee places and hotels leaves somewhat to be desired, sadly. I’m not quite sure yet it it’s their communication style or if it’s because I’m a foreigner (and might be mistaken for a russian somehow?).

In Part 3 of our series, we explored the hardware device elements of the Reolink RLC-810A ― focusing on the NAND memory. We continue with Part 4 of our exploration into an IP camera firmware through introducing the concept of a file system. Furthermore, we will explore the technical reasons for choosing the UBI File System (UBIFS), a file system used especially for a category of mass storage, and we will unpack the UBIFS part using the ub..

I love this blog post. Thank you for writing it. I must add one thing: every accessibility audit needs to test with forced colors. Countless sites claim to be accessible but fail this basic check. For those less familiar: forced colors is a standard feature defined in the CSS Color Adjustment Module Level 1 . It overrides colors with a user-preferred palette. Implementations include Windows High Contrast Mode and Firefox on all support....

Synapse is incredibly slow, which is why I run the Conduit matrix server . Server performance is the main price paid for Matrix’ history replication. This also gives Matrix a spam DDoS problem: sometimes people mass-create accounts on hundreds of servers with open registration, and mass-join rooms. The flood of thousands of join-events will OOM most connected servers. My Conduit server (RocksDB backend, 1 vCPU, 1GB RAM) is actually fast ....

Slack’s business logic for showing notification periodically appears in LinkedIn posts and such. In Slack’s original post, this diagram was meant to illustrate what logic was being transferred from the multiple Slack clients to the server, but the diagram has since been taken as an example of product complexity and how development is harder than it may sound . In contrast, I think the diagram obscures the intended logic, but the logic i....
