Clean code

0 likes•116 views
Clean code is code that is easy to understand and change over time. It uses descriptive names for variables and functions, keeps functions short and focused on single tasks, handles errors properly, avoids duplication, and uses comments sparingly to explain intent rather than state the obvious. Well-written code with intention-revealing names may not need many comments at all.

Best Practices For Writing Super Readable Code
The document provides best practices for writing readable code, including commenting code, consistent indentation and naming schemes, avoiding duplication through the DRY principle, and limiting deep nesting. It also recommends organizing files and folders logically, using both object-oriented and procedural programming appropriately, learning from open source code, and refactoring code to improve readability without changing functionality.
Why coding convention ?
Coding conventions provide guidelines for programming style, practices, and naming to make code more consistent, easier to understand, and maintainable. They set standards for indentation, brace style, naming conventions, and other aspects so that collaborators can work together effectively and consistently. While different styles can work, it is important for a team to agree on and stick to shared conventions.
Standard coding practices
Coding best practices include:
1. Using macros, constants and configuration values instead of hard-coded values.
2. Initializing local variables before use and explicitly initializing variables whose initial values are important.
3. Using global variables judiciously and avoiding unnecessary global variables.
Peer Review Guidelines
A few guidelines for peer reviews at Ombu Labs. Be nice, be constructive, suggest alternatives, start discussions, use Git branches, Github pull requests and keep it lean.
Make sure that the pull requests solve a concrete problem today. You can always refactor your solution later. Do not design for the future.
Keep it simple stupid and learn from the comments in your pull requests.
13 javascript techniques to improve your code
We all write codes in different ways with a different style and most of the times forgot about standardization.
Let’s discuss #JavaScript Techniques to Improve Your #Code.
https://goo.gl/QzN2J2
N5 Code Efficiency
Efficient code is code that achieves the desired result using fewer resources like memory, processing power or time. The document gives examples of inefficient code and how they could be made more efficient through techniques like using loops for repetition instead of writing the same code multiple times, storing multiple values in an array instead of separate variables, using elif and else statements in selection to avoid unnecessary comparisons, and using logical operators like and/or to combine conditions in an if statement.
Tdd - Test Driven Development
TDD involves writing tests before writing code to ensure code works as intended and allows for refactoring. The TDD process involves writing specifications, tests, and then code. Tests provide confidence that code works, help design better code, and act as documentation. Tests should be written even for code that currently works perfectly since requirements and needs change over time. The benefits of TDD include producing modular code that is easy to change and refactor.
Clean Code Pt I
This document discusses clean code and provides tips for writing clean code. It defines clean code as code that is readable, elegant, concise, and trustable through testing. Clean code does one thing well with minimal dependencies and clear intentions. Bad code can be difficult to read and maintain and bring down a company. The document recommends practicing clean code techniques like using meaningful names, minimizing comments, formatting code consistently, and writing small, focused functions to avoid technical debt and improve code quality.

WordCamp US: Clean Code
We want code that is easy to understand, re-usable, and flexible. But we are always up against deadlines, so we rush, and end up with code that is messy, buggy, hard to maintain, and makes us go slower even though we’re trying to go faster.
What is clean code? In this talk I’ll provide some answers to this question, and introduce you to 10 good habits that will help keep your code clean, such as the use of meaningful names for your variables and functions, and following the “Boy Scout Rule” (leave the code cleaner than you found it). I will even try to persuade you that using a lot of code comments is a sign that there are problems with your code.
TDD and Simple Design Workshop - Session 1 - March 2019
The document discusses test-driven development (TDD) and simple design. It introduces TDD and some of its core practices, including test-driven development, simple design, refactoring, and pair programming. It provides an agenda for a workshop that will cover these topics over three sessions, including extreme programming (XP), the four elements of simple design, test doubles, outside-in TDD, and SOLID principles. The workshop aims to communicate best practices for using technical practices to succeed with agile development.
Test Driven Development
The document discusses test-driven development (TDD) and design-driven development (DDD). It advocates for writing tests before code using short iterative development cycles. TDD helps produce clean code that fulfills requirements by making developers think about required behavior, providing documentation, and improving quality. Common objections to TDD are addressed, noting that it forces understanding of code and tests, creates reusable modular code, and drives simplicity. Guidelines for effective TDD include writing small focused tests with descriptive intentions that are independent and repeatable.
Presentation Test Driven Development
This document discusses test-driven development (TDD). It defines TDD as an evolutionary approach where tests are written before code to verify functionality. The TDD cycle involves writing a test, making it pass by writing code, and refactoring code and tests. Advantages include more consistent testing, clarified interfaces and behavior, and confidence to refactor. An example walks through writing tests for password requirements, developing code to pass tests, and refactoring code and tests.

Vladimir Romanov - How to write code that is easy to read and change? What should you do when you see a piece of code written years ago which is hard to understand? In my experience, this boils down to 4 principles that I would like to share along with some examples in Apex
Naming Standards, Clean Code
Meaningful variable and function names are important for clean code. Names should clearly indicate what the variable or function represents. Names like "temp", "x", or "flag" should generally be avoided as they do not convey purpose. Instead, names should be searchable and pronounceable terms from the problem domain. Additional context can be added through classes, namespaces, or prefixes if needed. Names of a moderate length, between 8-20 characters on average, tend to balance readability and understandability.

GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

A Deep Dive into ScyllaDB's Architecture
This talk will cover ScyllaDB Architecture from the cluster-level view and zoom in on data distribution and internal node architecture. In the process, we will learn the secret sauce used to get ScyllaDB's high availability and superior performance. We will also touch on the upcoming changes to ScyllaDB architecture, moving to strongly consistent metadata and tablets.
Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
"$10 thousand per minute of downtime: architecture, queues, streaming and fin...
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.

- 6. clean code
- 7. Clean code is code that is easy to understand and easy to change
- 9. C#
- 10. time effort care
- 12. concepts
- 13. Names Use intent-revealing names int d //elapsed time in days int elapsedTimeInDays; int daysSinceCreation; int daysSinceModification; int fileAgeInDays;
- 14. Use pronounceable names String genymdhms = ‘’ String genymdhms = ‘’ String generationTimestamp; String modificationTimestamp
- 15. Use one word per concept Be consistent. For example, don’t use get and fetch todothesame thingin differentclasses
- 16. Better Functions The smaller the better A function should only do one thing No nested control structure Less arguments are better Handle errors properly Don’t repeat yourself
- 17. Comments Don’t comment bad code, rewrite it
- 18. Comments If code is readable you don’t need comments // Check to see if the employee is eligible for full benefits if ($employee->flags && self::HOURLY_FLAG && $employee->age > 65) if ($employee->isEligibleForFullBenefits())
- 19. Comments Explain your intention in comments // if we sort the array here the logic becomes simpler in calculatePayment() method Warn of consequences in comments // this script will take a very long time to run
- 20. Comments Remove noisy comments // The day of the month. Int dayOfMonth; Never leave code commented
