Tier cache allows users to organize Cloudflare data centers into tiers, where only high tiers can request content from origin servers, and send content to lower tier servers closer to customers. Cloudflare adds a regional tier in between low and high tiers so low tiers can request content from regional tier before high tiers. This reduces the number of requests to high tiers, resulting in lower origin load and overall latency. Overall there's an average of 50-100ms improvement in tail cache hits using regional cache tiers.

Zig is a general-purpose programming language and toolchain for maintaining robust, optimal and reusable software. This article goes into the reasons Zig is challenging to learn: it’s new, it forces you to make choices, it’s pedantic, and it has compile time execution. However, the author believes that regardless of the difficulty in the beginning, Zig is definitely worth using and learning.
As a developer, it’s hard to estimate how long a project will take. This article is a deep dive on why projects always overrun. It provides a framework to improve future estimation, backing it up with a combination of anecdotal evidence and visualization. The key takeaway is that even a detailed estimate of the work required for a project can still miss significant “invisible” work. Some strategies and thoughts are provided to help not miss estimating such invisible work over time.
This article posits that artificial intelligence (AI) technology is highly capable of replacing executive roles in companies, especially considering its ability to learn from vast historical data. These roles consist of measurable tasks such as capital allocation, creation and execution of market strategy, and candidate selection more effectively than humans. However, the likelihood of this happening is low due to the power dynamics in businesses, with executives being the decision-makers about automation, thus protecting their roles.

Facebook and Instagram will block all news articles in California if state lawmakers pass a bill meant to funnel money from the tech platforms to media organizations, a Meta spokesman said in response to the bill. The proposed California Journalism Preservation Act would essentially tax the advertising profits platforms make from distributing news articles. Under the measure, some 70% of the money collected from the so-called "usage fee" would support newsrooms throughout the state.
GitHub stars are a common way of judging the maturity, reputation, and popularity of an open-source project. However, the number of stars a project has isn’t necessarily correlated with the actual value of the project. This article dives deep into the market of buying GitHub stars for projects and how to use other value radars to judge the quality of a project.

Finding your weak spots as a developer, leader, or in general can be difficult. There are various ways to identify your weaknesses, like taking on a “stretch” project, accepting code reviews, giving code reviews, and more. When identifying your weaknesses, it’s important to decide which ones will change your game if you work at it and improve them. Generally, the only way to improve weaknesses is through consistent and effortful practice.
This is a short transcript of a talk given by Professor John Ousterhout at Stanford. He talks about how it is really hard to build relationships that last for a long time. Professional relationships don’t last long because of “scar tissue” that builds up over time. In non-professional relationships, usually you can sit down and talk about things to prevent this build up, but in professional relationships, that opportunity usually doesn’t come around.

Passwordless authentication has been rising in popularity. It is more secure and convenient than password-based authentication. This article gives a thorough deep dive of the different forms of passwordless authentication and shows you how you can implement it.
Sometimes you have a lot of data. One approach to support quick searches is pre-processing it to build an index so a search can involve only looking at a small fraction of the total data. The threshold at which it's worth switching to indexing, though, might be higher than you'd guess. Unless you know from the start that you'll be searching hundreds of millions of records, consider starting with simple scans and only add indexing if you can't get acceptable performance. And even then, if queries are rare and highly varied it may still be better to do the work at query time instead of ingestion time.
The author proposes the Pareto principle of boredom: 80% of innovation comes from being bored 20% of the time. Boredom could actually be a good thing for engineers, as it could help cultivate some invention and creativity.
