Rails 8.1 introduces a new feature called local continuous integration (CI) that enables developers to run tests quickly on their own machines, reducing reliance on external CI services like GitHub Actions. This enhancement addresses common frustrations with slow CI processes and the time wasted switching between tasks. Local CI allows developers to define the necessary steps for testing, ensuring that applications can be deployed confidently and efficiently. While third-party CI services are popular due to their low cost and free tiers, they often require significant setup and

The author shares their experience implementing Coogle, a C++ search engine designed to locate function signatures in large codebases, especially those that include both C and modern C++ features. Inspired by Hoogle, a Haskell function search engine, the author initially focused on supporting simple types like `int` and `char`. However, they encountered an issue when trying to search for `std::string` signatures. Despite having many such functions in the test codebase, Coogle couldn't find any results.

The content discusses testing the performance limits of a simple application setup to determine how many HTTP requests per second a single machine can handle. The architecture consists of a single instance of an application and database, all managed by an automated Python script. The application generates 1,250,000 random rows in a database table and includes a simple security feature requiring a secret key for all requests. Testing was conducted on four DigitalOcean machines, each with 2 CPUs and 2 GB of memory, over short and

After optimizing backend services, databases, and API responses, users still experience slow page loads due to excessive connection establishment times during peak traffic—specifically related to TLS handshake saturation. While many view TLS as minimal overhead, it involves significant CPU-intensive cryptographic operations performed by load balancers. Under normal conditions, a TLS handshake takes about 20-30ms, but during traffic peaks, it can spike to 5 seconds due to queues forming when new requests outpace the load balancer's fixed number

The content discusses the capabilities of MacOS Tahoe, which can now generate SSH keys backed by the secure enclave, effectively replacing third-party solutions like Secretive. There is a shared library, `/usr/lib/ssh-keychain.dylib`, that has traditionally supported smartcard integration but now also implements the `SecurityKeyProvider` interface. This allows for direct loading of keys from the secure enclave and interaction with FIDO2 devices like Yubikeys. To create a secure enclave-backed key that requires

The speaker discusses their experience optimizing a RISC-V emulator to achieve an impressive performance of 550 million instructions per second through interpretation. They reflect on their journey in compiler development, particularly emphasizing the utility of two data structures: arenas and StringMaps. Arenas allow efficient bulk memory allocation, which is beneficial in compiler phases where memory isn't released incrementally. StringMaps facilitate efficient string management by using a hashmap for string indices, leading to reduced payloads and faster comparisons, akin to string interning. The
