Good Friday, commemorated annually on the Friday before Easter Sunday, marks the crucifixion of Jesus Christ, a pivotal event in Christianity despite its painful nature. Christians refer to it as "good" to signify its holiness and the monumental implications it has for sin absolution and human relationships with God, rather than implying a joyful occasion. The day is observed through events detailing Christ's suffering, including his arrest, flogging, and crucifixion, leading to his burial in a tomb. The term

The article discusses the size of packets in packet-switched networks, highlighting that while these networks have been in use for decades, the optimal packet size remains a debated topic. Currently, the default packet size in the Internet is between 20 and 1,500 octets. Packets larger than this can face fragmentation issues, while those smaller may compromise header integrity. Historical context is provided, noting that in 1981, the Internet Protocol Specification (RFC 791) recommended a maximum packet size of

The author has been seeking ways for developers to protect themselves from ineffective productivity management methods, which often rely on arbitrary targets and metrics. They note the continual resurgence of these misguided approaches and express frustration with outdated management practices. However, they've identified pair programming as a potential solution. By making pair programming a requirement rather than an occasional practice, developers could collectively avoid individual performance scrutiny, as performance would no longer be tied to single individuals. To implement this, task management tools would need to be adapted so that

The feedback provided is taken seriously, and users are encouraged to consult the documentation for all available qualifiers. The repository features a lightweight tracing engine suitable for profiling multithreaded applications, offering low overhead (8-12 nanoseconds per event). It performs faster than other time-tracing methods but lacks portability, primarily supporting Windows 10+ and Ubuntu 20+ on x64 architectures. This tool is beneficial for observing complex multithreading issues that sampling profilers may miss, making it useful for diagnosing

Last week, Apple rolled out iOS 18.4 for supported iPhones, and a bug was discovered in applications that utilize dynamic symbol resolution via dlsym() on devices with pointer authentication (PAC). This issue was first identified in a custom iOS app compiled for the arm64e architecture. The app uses dlopen() and dlsym() to dynamically load system function addresses, such as strcpy, which worked as expected. However, when attempting to resolve the strcmp function, the application

The content discusses implementing IP restrictions in a Rails application to allow corporate customers to whitelist specific IPs for their accounts. The approach involves storing the whitelisted IPs in a database due to the account-specific and optional nature of the requirement. While a simple solution using a `before_action` is considered, it poses performance issues since it requires querying the database for every request. To address performance concerns, caching the whitelisted IPs in Redis or Memcache is suggested, reducing database overhead and improving scalability.
