Jose Zarazua discusses a technique for filtering candidates applying for remote programming positions. He suggests including a simple programming knockout question in the application process to help identify unqualified developers amidst the high volume of applications. The question centers around determining the result of some code, where the answer reflects a candidate's ability to interpret code quickly. Zarazua shares results from his time as CTO at MonetizeMore, noting that about 50% of candidates incorrectly used an AI or interpreter to answer, while

Docker has introduced hardened images (DHI), which are minimal and secure container images aimed at enhancing security for developers. Released in May 2025 and later made open source in December under the Apache 2.0 license, these images support all developers, not just large enterprises. Key features of DHI include: - **Minimalist Design:** They use a distroless runtime, reducing the attack surface by eliminating non-essential tools. - **Significant Size Reduction:** DHI is up to

On January 14, 2026, Cursor published a blog post discussing their experiments with running autonomous coding agents for extended periods, aiming to complete projects that typically require significant human effort. They explored various approaches, identified failures, and eventually developed a system that addressed coordination problems, allowing them to scale projects effectively. As a test of their system, they attempted to build a web browser from scratch. The agents ran for nearly a week, generating over 1 million lines of code across 1,000

On September 16, 1979, eight individuals from two families successfully escaped from East Germany to West Germany using a homemade hot air balloon after over a year of preparation. Initially, they attempted to flee two months earlier but were unsuccessful, prompting East German authorities to investigate the plot without being able to identify the escapees. Despite the heavily fortified border, including the Berlin Wall and armed soldiers, the group, led by Peter Strelzyk and Günter Wetzel, devised their escape plan inspired by

Let’s Encrypt has launched short-lived and IP address certificates, which are valid for 160 hours (just over six days). To obtain a short-lived certificate, users can select the ‘shortlived’ profile in their ACME client. These certificates enhance security by necessitating more frequent validation, thus minimizing reliance on unreliable revocation methods. Traditional certificates can leave users vulnerable for up to 90 days if a key is compromised, but short-lived certificates significantly reduce this vulnerability window. While these certificates are

The author discusses their experiences with ClickHouse, a columnar database used at their workplace to process large volumes of data, specifically billions of records and hundreds of terabytes. They outline the performance of various queries, noting that ClickHouse processes 220 billion records in 17 seconds without classic indexing, as seen in relational databases. The "state" field in the database, defined as LowCardinality(String), does not have a classic index but performs efficiently due to its limited number of unique values. The

This tutorial, sourced from GitHub, focuses on the concept of unikernels, which offer a specialized type of virtual machine designed to improve performance while maintaining security. While typical virtual machines provide strong isolation and security, they often compromise on performance due to longer boot times and resource allocation challenges. Micro VMs aim to reduce memory usage and improve boot times but still rely on general-purpose operating systems. Unikernels address these issues by eliminating unnecessary components, resulting in a lightweight and efficient solution. The tutorial will

The content critiques the perception that Lenovo and IBM genuinely prioritize user experience with ThinkPad laptops. It argues that discussions about the popularity of ThinkPads often romanticize the brands as kind and benevolent, which the author dismisses as a fantasy. The piece suggests that many enthusiasts fail to consider ThinkPads outside of personal use, neglecting their operational context in business environments. The author contends that the focus on user care overlooks how these laptops are designed primarily for profit, examining the business models of IBM and

In November, a UPS MD-11F freighter aircraft crashed in Kentucky, resulting in 15 fatalities, including three crew members and 12 people on the ground. Investigators from the US National Transportation Safety Board (NTSB) revealed that the crash was linked to a structural flaw in the engine mounting assembly, which Boeing had identified on similar aircraft 15 years ago. The engine detached from the wing as the plane attempted to take off from Louisville, leading to the crash in an industrial area

The service offers instant Linux boxes accessible via SSH without the need for signup or configuration, allowing users to pay only for what they use. Management of the boxes and billing is done through simple commands, with a minimum top-up of $10. Boxes will automatically stop functioning when the balance drops below $5 and will be deleted when the balance reaches $0. Users of OpenSSH 9.0+ must use the -O flag to access the legacy SCP protocol.

The author, frustrated with Windows 11, has been experimenting with Wine to run Windows-exclusive software on Linux. This exploration involves understanding system calls (syscalls), which are the services provided by the operating system to applications for tasks like file handling and memory allocation. The key distinction highlighted is that while Linux applications directly invoke the syscall instruction, Windows applications use the WinAPI functions, which internally manage communication with the OS kernel. Wine's role is to simulate a Windows environment by loading Windows executables and
