Welcome to issue 18 of Programmer Weekly. Let's get straight to the links this week.

Quote of the Week

 

“It's hard enough to find an error in your code when you're looking for it; it's even harder when you've assumed your code is error-free.” - Steve McConnell

News

By translating Keller’s conjecture into a computer-friendly search for a type of graph, researchers have finally resolved a problem about covering spaces with tiles.

It's hardly a return to the glory days of the 1960s, but IBM Z Series mainframes look like they are more than getting by with a little help from their open source friends. IBM's Ross Mauri talks about the role Red Hat's software has played in boosting mainframe sales.

Botnet is hard to detect and with no centralized control server, harder to take down.

Azure Cosmos DB serverless is now available in preview on the Core (SQL) API, with support for the APIs for MongoDB, Gremlin (graph), Table, and Cassandra coming soon. This new consumption-based model lets you use your containers cost-effectively, without having to provision any throughput.

Learn how to build an end-to-end computer vision program for building optimal peanut butter and banana sandwiches.

When we talk about “ARM32” the proper ARM name for this is Aarch32 and what is implemented physically in the ARMv4 thru ARMv7 ARM architectures. This post discusses how the kernel bootstraps itself from executing in physical memory after decompression/boot loader and all the way to executing generic kernel code written in C from virtual memory.

Looking beyond the speed of delivery to identify what's really slowing your team down.

Distributed systems are tricky. Multiple unreliable machines are running in parallel, sending messages to each other across network links with arbitrary delays. How can we be confident these systems do what we want despite this chaos?

In this article, we’ll define a basic regular expression language using a formal grammar and learn how to parse its strings in linear time using the recursive descent method. We’ll use the BNF notation for the grammars.

This post explains the creation of a simple Kubernetes Operator so that you can understand the main concepts behind it and what it is aimed for. It starts with the main concepts and then moves on to hands-on where you will learn how to create one k8s Operator from the ground up.

This post discusses an effective set of patterns for large-scale JavaScript application architecture. 

In this post, we'll talk about how to establish a peer-to-peer connection between two machines, in spite of all the obstacles in the way.

Testing service dependency timeouts, retries, and circuit-breaker configurations is essential. This post presents an open source approach to failure injection on Amazon EC2 using AWS Systems Manager, and we demonstrate how Prime Video combines it with load testing to achieve higher levels of resiliency. This Prime Video case study shows how chaos engineering helps prevent potentially customer-impacting issues that are difficult to pinpoint using traditional testing methods.

Much like the DMV, the PostgreSQL query planner is a powerful, mysterious entity to whom we semi-blindly entrust our well-being. It has the crucial responsibility of picking the most efficient execution plan for every query. Here we’ll explore what data Postgres takes into account when creating query plans, and how we used that context to help the query planner come up with more efficient plans for some of our most important query patterns.

Learn how to turn your Raspberry Pi 3 into a wifi hotspot using Fedora and NetworkManager in this article.

Get started with WebAssembly through this simple hands-on tutorial that assumes only general knowledge in web development. The only tools you’ll need to get a taste of Wasm through runnable code examples are a code editor, any modern browser, and a Docker container with toolchains for C and Rust that comes with the article.
