Why you should check values of public methods’ parameters
▻https://hownot2code.com/2021/10/22/why-you-should-check-values-of-public-methods-parameters

This note will answer the question – why PVS-Studio considers parameters of public methods potential sources of tainted data. The analyzer can issue warnings if such parameters haven’t been checked before use. The point is that undue confidence in external data may lead to various vulnerabilities – SQLI, XSS, path traversal and others. Most obvious … Continue reading Why you should check values of public methods’ parameters

Nor do I mean fast like the 30 minutes it took for Pebble Watch to raise $1 million on Kickstarter. Think faster. Think about the speed of innovation in today’s world. Think about how many startups are formulated within the minds of new computer science majors at the dorms of Cal. Think about apps being designed at the seemingly infinite amount of techie-targeted cafes in Silicon Valley. There will never be a lack of ideas in our technology dominated world.

If you ever developed a SPA (Single-Page-Application), where ever it was on Angular, #react, Vue or something else, You probably noticed that all the hard work you’ve put into your app goes to one minified .js file and one .css file. Those files contain all your dependencies and functionalities of the app.sometimes, those files could become quite big and increase the loading time of your app this something I stumbled upon during my work.With #webpack for example, the files are made after “Tree-shaking “ and Uglify.Tree-shaking is the process of removing all the unused function and variables from the code, which makes our app a lot smaller (basically we only use a small part of our dependencies and a large part of the code isn’t even being called).Uglify (as it sounds like) is the process of (...)

Graph TheoryGraph Data Structures and Traversal Algorithms Made EasyThe graphs in computer software are a little different from the bar graphs in high school. Sure, they are still a mapping of relations just represented differently. Graphs can actually help solve a really large number of problems. They can be used to solve problems in social networking, eg. finding relations between friends or friends of friends or in GPS navigation, finding an optimal route from your house to the nearest shopping center. Graphs are used regularly in robotics and AI, for example, sometimes for maintaining all the possible states a robot is allowed to be in (so they don’t break stuff or move through walls). They’re great for scheduling problems, like when to schedule traffic flow (which can be solved with (...)

What if there was a way to remove opinions and personal preferences from the equation and unambiguously determine what code is better given two competing solutions?The only thing that developers have to agree upon is the axiom itself. With unanimity reached on this single point, mountains of subjective discussions suddenly become irrelevant and valuable time is reclaimed.Deference to unwanted authority is unnecessary as we make progress to a decentralized world.A handrail becomes available for developers to help them make countless decisions throughout their days. The haunting feeling of uncertainty is replaced with welcomed confidence.I came up with this idea about 5 years ago and it has withstood intense scrutiny from developers and architects at various companies since then.

Git hooks are one of the most underrated git features, and have the potential to increase your productivity as a developer. Have you ever wanted to run a command every time you commit or push?

Read on to find out how hooks could improve your workflow.Why use git hooks?I came to learn about hooks after embarking on a quest to automate my own workflow. You see, for better or worse, I make use of FIXME: comments in my code to remind myself to revisit something.

Also, we compare our Sieve of Eratosthenes implementation in MPI and the same algorithm in #spark just to discover how they both behave while looking at some interesting implementation details.In the second part of the series, we are going to implement Matrix Multiplication in both, MPI and Apache Spark. Again, we will look at how each implementation behaves when running on MapR.

JSON Web Token (JWT, often pronounced “jot”) is a powerful tool for confidently transmitting data between two parties through tokens. These parties can consist of users, servers, or any other combination of services. Based on an open standard (RFC-7519), JWTs are digitally signed with an encryption algorithm, so the receiving party can trust the information contained within. In computer #security this concept is known as Data Integrity.One main benefit of using a #jwt is that it’s very compact (assuming the issuer uses JWS Compact Serialization, which is recommended). They are generally small enough to be sent through a POST request, in an HTTP Header, or even as a query string within a URL. However, the more claims you add to a JWT, the more bloated it becomes. You could theoretically (...)
