Signs that you're a good programmer - Software Engineering Tips
The most frequently viewed page on this site is Signs you're a bad programmer, which has also now been published on dead trees by Hacker Monthly, and I think that behoves me to write its antithesis. "Bad programmer" is also considered inflammatory by some who think I'm speaking down to them. Not so; it was personal catharsis from an author who exhibited many of those problems himself. And what I think made the article popular was the "remedies"--I didn't want someone to get depressed when they recognized themselves, I wanted to be constructive. Therefore if you think you're missing any of the qualities below, don't be offended. I didn't pick these up for a while, either, and many of them came from watching other programmers or reading their code. 1. The compiler and runtime can often answer a question faster than a human can. Symptoms How to acquire this trait Are you excessively cautious? Note: A programmer who "suggests wacky and unrealistic solutions" is not always a bad programmer. 2.

A difícil busca de autorealização
Hoje vigora vastamente uma erosão de valores éticos que normalmente eram vividos e transmitidos pela família e depois pela escola pela sociedade. Essa erosão fez com que as estrelas-guia do céu da ética ficassem encobertas por nuvens de interesses danosos para a sociedade e para o futuro da vida e do equilíbrio da Terra. Não obstante esta obscuridade, importa reconhecer também a emergência de novos valores ligados à solidariedade internacional, ao cuidado para com a natureza, à transparência nas relações sociais e à rejeição de formas de violência política repressiva e da transgressão dos direitos humanos. As crises recentes denunciaram máfias de especuladores instalados nas bolsas e nos grandes bancos cujo volume de rapinagem de dinheiros alheios quase levou à derrocada todo o sistema financeiro mundial. Penso que esta autorealização só se consegue se incorporar seriamente três outras dimensões. A terceira dimensão é alimentar certo nivel de espiritualidade. Curtir isso:
Signs that you're a bad programmer - Software Engineering Tips
Why was this written? Most of these faults were discovered the hard way by the author himself, either because he committed them himself or saw them in the work of others. This paper is not meant for grading programmers, it was intended to be read by programmers who trust their ability to judge when something is a sign of bad practice, and when it's a consequence of special circumstances. This paper was written to force its author to think, and published because he thinks you lot would probably get a kick out of it, too. 1. Reasoning about code means being able to follow the execution path ("running the program in your head") while knowing what the goal of the code is. Symptoms Remedies To get over this deficiency a programmer can practice by using the IDE's own debugger as an aide, if it has the ability to step through the code one line at a time. 2. Object Oriented Programming is an example of a language model, as is Functional or Declarative programming. 3. 4. 5. 6. 1. 2. 3. 4. 5. Symptoms
Stack versus Heap
The differences between the stack and the heap can be confusing for many people. So, we thought we would have a list of questions and answers about stacks and heaps that we thought would be very helpful. Where are the stack and heap stored? They are both stored in the computer’s RAM (Random Access Memory). How do threads interact with the stack and the heap? In a multi-threaded application, each thread will have its own stack. Can an object be stored on the stack instead of the heap? Yes, an object can be stored on the stack. Code to create an object on the stack: void somefunction( ) { /* create an object "m" of class Member this will be put on the stack since the "new" keyword is not used, and we are creating the object inside a function */ Member m; } //the object "m" is destroyed once the function ends So, the object “m” is destroyed once the function has run to completion – or, in other words, when it “goes out of scope”. Code to create an object on the heap:
gerrit - Gerrit Code Review
Web based code review and project management for Git based projects. Objective Gerrit is a web based code review system, facilitating online code reviews for projects using the Git version control system. Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer. Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer. To see Gerrit in the wild, checkout our ShowCases page.

What is a Full Stack developer? | Laurence Gellert's Blog
Is it reasonable to expect mere mortals to have mastery over every facet of the development stack? Probably not, but Facebook can ask for it. I was told at OSCON by a Facebook employee that they only hire ‘Full Stack’ developers. To me, a Full Stack Developer is someone with familiarity in each layer, if not mastery in many and a genuine interest in all software technology. Good developers who are familiar with the entire stack know how to make life easier for those around them. Server, Network, and Hosting Environment.This involves understanding what can break and why, taking no resource for granted.Appropriate use of the file system, cloud storage, network resources, and an understanding of data redundancy and availability is necessary.How does the application scale given the hardware constraints? Other Pieces of the Puzzle: Ability to write quality unit tests. Closing Thoughts: It is very bad practice to tightly couple code to a specific implementation (library, OS, hardware, etc).
