In TypeScript (TS), the `void` type symbolizes "nothing," distinct from "nothing" in JavaScript (JS). It primarily indicates that a function does not return a meaningful value, typically returning `undefined`. Variables declared as `void` can only hold the value `undefined`, making such declarations generally impractical in development. When a function’s return type is specified as `void`, it may return `undefined`, while JS functions without explicit returns also yield `undefined`. Importantly, functions

Passknight is a user-configured, cross-platform cloud-hosted password manager that utilizes Firestore for secure credential and note storage. It supports multiple users and vaults for better organization. On Android, users must set Passknight as their autofill service, which may require manual field selection via a browser extension if autofill hints are not available. Passknight's security measures are inspired by Bitwarden, ensuring that even if the vault is compromised, the encrypted data remains secure, as the

JavaScript operates in a single-threaded environment but manages multiple tasks concurrently through its Event Loop. The Event Loop is essential for mastering asynchronous operations and writing efficient, non-blocking code. Key components include: - **Call Stack**: Tracks function execution using a Last In, First Out principle—functions are added when called and removed upon completion. - **Event Loop Mechanics**: Continuously checks if the call stack is empty and looks for tasks in the task queue. When the stack is clear

Running 32-bit legacy applications on 64-bit Linux systems is common, and this is also supported on the AArch64 architecture. To enable this compatibility, the CONFIG_COMPAT option must be enabled in the kernel configuration. However, a key issue arises because, unlike x86_64 systems that can generate both 64-bit and 32-bit applications using the same GCC toolchain with a simple flag, AArch64 requires separate GCC toolchains for each architecture. The challenge comes when building a

In his blog post, Joe Doyle emphasizes the critical importance of not reusing nonces (numbers used once) in cryptography, as doing so can compromise security by revealing encrypted messages or leaking secret keys. The post narrates a cautionary tale about a bidirectional encrypted channel, such as those used in encrypted voice calls or chats, highlighting that subtle issues can arise in networks with multiple encrypted channels. It details a discovered bug in a client’s threshold signature scheme, where different parties used the same sequence

The author suggests that there are many misconceptions about TCP (Transmission Control Protocol) that software developers often hold, which can lead to misunderstandings and issues in network programming. They outline several false beliefs, emphasizing that these statements may not always be true: 1. TCP guarantees that all data sent will be received. 2. TCP is mostly reliable rather than fully reliable. 3. There isn't a guaranteed agreement on received bytes on both ends. 4. Building application-level protocols on TCP does not assure complete reliability.

In an article by Martin Fowler, he discusses the common trend among teams utilizing microservices architecture and suggests a "monolith-first" strategy for new projects. He argues that microservices, while beneficial for complex systems, come with a significant "Microservice Premium"—the added complexity of managing multiple services—which can hinder productivity in simpler applications. Fowler emphasizes the principle of Yagni ("You Aren't Gonna Need It"), advocating for the initial development of a straightforward monolith to quickly validate software ideas

The content discusses the concept of "design it twice" from Chapter 11 of "A Philosophy of Software Design." The author emphasizes the importance of generating multiple design options rather than settling on the first idea that comes to mind. By forcing oneself to consider at least two distinct designs, one can make better decisions and ultimately find the most effective solution. The author shares a personal experience where failing to apply this practice led to a poorly prepared design presentation, highlighting the significance of comprehensive planning. The key takeaway is

In recent years, the U.S. government has increasingly emphasized the importance of memory safety in programming due to vulnerabilities in critical infrastructure systems that predominantly use C and C++. Key government documents, including guidance from the NSA and CISA, highlight the urgent need for memory-safe languages to protect against software vulnerabilities. Research indicates that a significant percentage of security exploits are linked to memory corruption, with Microsoft noting that 70% of its vulnerabilities could be mitigated by using memory-safe languages. Professionals are advocating
