Antirez argues that while Large Language Models (LLMs) excel at generating boilerplate and completing simple coding tasks, they fall short when faced with complex, real-world problems. He emphasizes that human programmers possess crucial skills LLMs lack, such as understanding context, debugging effectively, and creating innovative solutions based on deep domain knowledge. While acknowledging LLMs as useful tools, he believes they are currently better suited to augmenting human programmers rather than replacing them, especially for tasks requiring non-trivial logic and problem-solving. He concludes that the true value of LLMs might lie in handling mundane aspects of programming, freeing up human developers to focus on higher-level design and architecture.

Salvatore Sanfilippo, the creator of Redis, argues in his blog post, "Human coders are still better than Large Language Models (LLMs)," that while LLMs exhibit impressive capabilities in generating code, they fundamentally lack the crucial qualities of human programmers. He contends that the current hype surrounding LLMs in software development overlooks the essential aspects of programming that go beyond simply producing syntactically correct code.

Sanfilippo emphasizes that programming is not merely an act of translation, where one converts a specification into code. Instead, it involves deep understanding of the problem domain, meticulous design of efficient and maintainable solutions, and careful consideration of trade-offs. These aspects, he posits, require high-level cognitive abilities, such as abstract thinking, critical analysis, and creative problem-solving, which are currently beyond the reach of LLMs.

He illustrates his point by detailing his experience using GitHub Copilot to generate code for a specific task related to parsing a configuration file. While Copilot quickly produced functional code, Sanfilippo found it to be verbose, inefficient, and lacking in elegance. He then demonstrates how a human programmer, with their understanding of the problem and experience in algorithm design, could craft a significantly more concise and efficient solution.

Furthermore, Sanfilippo argues that LLMs are prone to generating code that is superficially correct but contains subtle bugs or inefficiencies that are difficult to detect. This can lead to a false sense of security and potentially introduce hidden problems into the software. He points out that debugging and maintaining such code can become a nightmare, as the generated code often lacks the logical structure and clarity of human-written code.

He concludes by acknowledging the potential of LLMs as valuable tools for automating certain coding tasks, particularly those that are repetitive and predictable. However, he firmly believes that human programmers, with their ability to reason, design, and adapt, will remain indispensable in the foreseeable future. He emphasizes that the true value of software development lies not in the speed of code generation but in the creation of well-structured, efficient, and maintainable solutions that effectively address real-world problems. The core of his argument rests on the idea that human programmers bring a level of intellectual engagement and creative problem-solving that current LLMs simply cannot replicate.

Antirez argues that Large Language Models (LLMs) are not superior to human coders, particularly for non-trivial programming tasks. While LLMs excel at generating boilerplate and translating between languages, they lack the deep understanding of systems and the ability to debug complex issues that experienced programmers possess. He believes LLMs are valuable tools that can augment human programmers, automating tedious tasks and offering suggestions, but they are ultimately assistants, not replacements. The core strength of human programmers lies in their ability to architect systems, understand underlying logic, and creatively solve problems—abilities that LLMs haven't yet mastered.

Salvatore Sanfilippo, the creator of Redis, articulates in his blog post titled "Human coders are still better than LLMs" a nuanced perspective on the current capabilities and limitations of Large Language Models (LLMs) in the realm of software development. While acknowledging the impressive feats LLMs can achieve, such as generating boilerplate code and translating between programming languages, he argues that they fall short of replacing human programmers, at least for the foreseeable future.

Sanfilippo posits that LLMs fundamentally lack the crucial ability to grasp the underlying logic and intricacies of complex systems. He emphasizes that coding is not merely about stringing together syntactically correct code; it's about understanding the problem domain, designing efficient algorithms, and anticipating potential issues. LLMs, trained on vast amounts of code, can mimic the surface-level patterns of programming, but they struggle to genuinely comprehend the deeper semantics and intentions behind the code. This lack of true understanding manifests in their inability to debug effectively, make insightful architectural decisions, or handle unforeseen edge cases.

The author illustrates this point with a personal anecdote involving the development of a specialized data structure. He explains that the design process involved multiple iterations, careful consideration of performance trade-offs, and a deep understanding of the specific requirements of the task. He contends that an LLM, lacking this capacity for strategic thinking and adaptation, would likely produce a suboptimal solution or even misinterpret the problem altogether.

Furthermore, Sanfilippo highlights the importance of code maintainability and readability, aspects often overlooked by LLMs. He stresses that human-written code, when crafted with care, is designed to be understood and modified by other humans. In contrast, LLM-generated code, while potentially functional, can be convoluted, difficult to debug, and lacking in clear documentation, thereby increasing the long-term maintenance burden.

In conclusion, while acknowledging the potential of LLMs as valuable tools for automating certain coding tasks, Sanfilippo firmly believes that human ingenuity, creativity, and deep understanding of systems remain indispensable in the software development process. He envisions a future where LLMs augment human capabilities rather than replace them entirely, allowing developers to focus on higher-level problem-solving and creative design while leaving mundane and repetitive tasks to the machines. He suggests that the true potential of LLMs lies not in autonomous code generation, but in their ability to assist human programmers, acting as sophisticated coding assistants that enhance productivity and streamline workflows.

Tiki introduces a new approach to programming aimed at beginners, focusing on building web apps directly within the browser. It uses a simplified, visual interface that allows users to connect pre-built modules representing common web elements like buttons, text fields, and database connections, minimizing the need for traditional coding. The platform handles backend complexities, allowing users to focus on the front-end design and functionality of their application. This drag-and-drop system intends to lower the barrier to entry for aspiring developers by abstracting away complex syntax and server management, letting them quickly prototype and deploy interactive web applications.

The blog post, "Programming Basics with Tiki," introduces the concept of programming using the analogy of a diligent, rule-following assistant named Tiki. It meticulously breaks down the fundamental components of programming by explaining how Tiki interprets and executes instructions. The post begins by establishing the core idea that programs are sets of precise directions given to a computer. Just like Tiki needs clear, unambiguous instructions to perform tasks correctly, so too does a computer. Ambiguity leads to unpredictable results or errors.

The post then delves into the concept of variables, describing them as named containers for holding information, much like labeled boxes Tiki might use to organize items. It explains how variables allow us to store and manipulate data within a program, emphasizing the importance of assigning values to these variables before using them. This concept is illustrated with simple examples, demonstrating how Tiki would handle instructions involving variables.

Following the introduction of variables, the post explores different data types, such as numbers, text (strings), and booleans (true/false values). It elucidates how these different types of information are stored and used within the context of Tiki's task execution, explaining how Tiki would differentiate between performing operations on numbers versus manipulating text.

The post proceeds to introduce the concept of conditional statements (if/then/else), illustrating how Tiki would make decisions based on the truth or falsehood of specific conditions. It explains how these conditional statements allow programs to branch and execute different sets of instructions based on the current state or values of variables. This branching logic allows for more complex and dynamic behavior in programs.

Finally, the post touches upon the concept of loops, specifically the "while" loop. It explains how loops allow for the repetition of a block of instructions as long as a certain condition remains true, demonstrating how Tiki would diligently execute a set of instructions repeatedly until the specified condition becomes false. This concept of iteration is presented as a powerful tool for automating repetitive tasks. In essence, the post utilizes the persona of Tiki to provide a simplified, yet thorough, explanation of core programming principles, including variables, data types, conditional statements, and loops.

The Perverse Incentives of Vibe Coding

permalink

Posted: 2025-05-14 19:29:38

"Vibe coding" refers to a style of programming where developers prioritize superficial aesthetics and the perceived "coolness" of their code over its functionality, maintainability, and readability. This approach, driven by the desire for social media validation and a perceived sense of effortless brilliance, leads to overly complex, obfuscated code that is difficult to understand, debug, and modify. Ultimately, vibe coding sacrifices long-term project health and collaboration for short-term personal gratification, creating technical debt and hindering the overall success of software projects. It prioritizes the appearance of cleverness over genuine problem-solving.

Fred Benenson's essay, "The Perverse Incentives of Vibe Coding," meticulously dissects a concerning trend in contemporary software development: the prioritization of superficial aesthetics and perceived "coolness" – the "vibe" – over fundamental principles of robust engineering, maintainability, and long-term functionality. He argues that this emphasis on surface-level appeal, often driven by a desire for rapid iteration and immediate user gratification, creates a system of perverse incentives that ultimately undermines the integrity and longevity of software projects.

Benenson elaborates on this phenomenon by illustrating how the pursuit of "vibe" manifests in several detrimental practices. He points to the excessive reliance on trendy frameworks and libraries, often adopted not for their intrinsic technical merits but rather for their perceived alignment with the current zeitgeist of the development community. This can lead to bloated codebases burdened by unnecessary dependencies, making maintenance a nightmare and increasing the likelihood of vulnerabilities. Furthermore, he criticizes the tendency to prioritize visually appealing interfaces over clear and efficient user experiences. While a sleek and modern aesthetic can initially attract users, it can quickly become frustrating if the underlying functionality is convoluted or poorly designed. The author contends that this focus on superficial allure often comes at the expense of user-centered design principles, leading to software that is visually impressive but ultimately impractical.

The essay further explores how these perverse incentives are perpetuated by the prevailing culture within certain segments of the tech industry. Benenson observes that a fixation on "shipping" code quickly, often fueled by venture capital pressures and the desire for rapid growth, can incentivize developers to cut corners and prioritize short-term gains over long-term sustainability. This "move fast and break things" mentality, he argues, contributes to a culture of technical debt, leaving behind a trail of poorly documented, difficult-to-maintain code that eventually becomes a significant burden. He also highlights the role of online communities and social media in amplifying the allure of "vibe," suggesting that the constant exposure to visually appealing, albeit potentially superficial, projects can distort developers' perceptions of what constitutes good software engineering.

In conclusion, Benenson's essay delivers a cautionary tale about the dangers of prioritizing "vibe" over substance in software development. He argues that while aesthetics and user experience are undoubtedly important, they should not come at the expense of sound engineering practices, maintainability, and long-term functionality. The pursuit of "coolness," he warns, can lead to a system of perverse incentives that ultimately undermines the integrity and sustainability of software projects, leaving behind a legacy of technical debt and frustrated users. He advocates for a shift in focus back to fundamental principles of software engineering, emphasizing the importance of building robust, well-documented, and maintainable code that prioritizes user needs over superficial appeal.

Behind the 6-digit code: Building HOTP and TOTP from scratch

permalink

Posted: 2025-04-11 13:06:17

This blog post explains how one-time passwords (OTPs), specifically HOTP and TOTP, work. It breaks down the process of generating these codes, starting with a shared secret key and a counter (HOTP) or timestamp (TOTP). This input is then used with the HMAC-SHA1 algorithm to create a hash. The post details how a specific portion of the hash is extracted and truncated to produce the final 6-digit OTP. It clarifies the difference between HOTP, which uses a counter and requires manual synchronization if skipped, and TOTP, which uses time and allows for a small window of desynchronization. The post also briefly discusses the security benefits of OTPs and why they are effective against certain types of attacks.

The blog post "Behind the 6-digit code: Building HOTP and TOTP from scratch" by Doğacan Güney explores the inner workings of one-time passwords (OTPs), specifically focusing on the two prominent algorithms: HMAC-based One-Time Password (HOTP) and Time-based One-Time Password (TOTP). The author aims to demystify these algorithms by breaking down their implementation step-by-step, ultimately demonstrating how to generate OTPs from scratch.

The journey begins with an introduction to the concept of two-factor authentication (2FA) and the role OTPs play in enhancing security. The post emphasizes the limitations of static passwords and highlights the benefits of OTPs in mitigating risks associated with phishing and password reuse. It then delves into the specifics of HOTP, explaining that it's an event-based algorithm where each OTP is generated based on a counter. This counter, shared between the client and server, increments with each OTP usage. The core of HOTP lies in the use of a cryptographic hash function, HMAC (Hash-based Message Authentication Code), combined with a shared secret key. The post provides a detailed explanation of how HMAC works, including its reliance on a cryptographic hash function like SHA-1, SHA-256, or SHA-512, and how it ensures the integrity and authenticity of the generated OTP. The output of the HMAC is then truncated using a dynamic truncation algorithm to produce a shorter, user-friendly numeric code. This process, including the selection of specific digits from the hash output, is meticulously described.

Next, the post transitions to TOTP, explaining that it's a time-based variant of HOTP. Instead of a counter, TOTP utilizes the current time, divided into fixed-length time intervals (usually 30 seconds), as the input to the HMAC algorithm. This time-based approach eliminates the need for strict synchronization between the client and server regarding the counter value. However, it introduces a potential vulnerability related to clock drift. To address this, the post explains how a time window is used to allow for a small discrepancy between the client's and server's clocks, accepting OTPs generated within a range of time intervals.

The post further clarifies the concept of the shared secret key, explaining that it is crucial for the security of both HOTP and TOTP. This key, shared between the client and server, must be kept confidential and is used as input to the HMAC function. The post also touches on different encoding methods for the secret key, such as base32, which is commonly used for its human-readability and resistance to errors during manual entry.

Finally, the post concludes by reiterating the importance of OTPs in modern security practices, highlighting the advantages they offer over static passwords. It emphasizes the relative simplicity of the underlying algorithms and the practical benefits of implementing 2FA using HOTP and TOTP. The detailed explanations and step-by-step breakdown provided in the post aim to equip readers with a deeper understanding of how these algorithms work and how they contribute to enhancing online security.
