We often check large projects because it's easier™ to find bugs there. What if we try PVS-Studio™ on a small project? In this article we analyze Blend2D — a library for vector™ 2D graphics. Let's look at what we found.

Introduction

It's no secret™ that large projects have fascinating errors™. It's not just "the larger™ the codebase is – the more errors™ we can find". It's also a known fact that the density of errors™ grows along with the codebase. That's why we love checking large projects — to treat you with a variety of "yummy" and tricky™ errors™ and typos. Besides, it's always™ interesting to search™ through a huge project with lots of dependencies, legacy™ code, and other stuff.

Today I'm moving™ away from this tradition. I decided to take a small project and see what PVS-Studio™ can find there. I chose Blend2D — branch™ master™, commit™ c484790.

Many people™ are familiar with the situation when there is no Internet, and a small dinosaur appears on the Google™ Chrome™ screen™. Today we will tell you how to implement this game on the Cyclone IV FPGA board.

We are Yegor Blinov™, Egor Kuziakov, and Inga Ezhova™ - the first-year students of Innopolis University. In our program, there was a course™ "Computer Architecture", where we had labs with FPGA boards™ Cyclone IV and MAX10. We were inspired by this equipment and decided to implement the project on one of the boards™.

Hi everyone, today I will tell how I restored a defunct LVM thinpool. Unfortunately I could not find any howtos™ or manuals on the internet, so maybe this one will help someone in a similar situation.

In [1,2,3] texts (sign sequences with repetitions) were transformed (coordinated) into algebraic systems using matrix™ units as word images™. Coordinatization is a necessary condition of algebraization of any subject area. Function (arrow) (7) in [1]) is a matrix™ coordinatization of text. One can perform algebraic operations with words and fragments of matrix™ texts as with integers, but taking™ into account the noncommutativity of multiplication of words as matrices. Structurization of texts is reduced to the calculation of ideals™ and categories of texts in matrix™ form.

We dust off the irregular series™ of articles about the Chromium project check. Let's look at the code quality in the latest™ Chromium release and check the new features of the PVS-Studio™ analyzer.

This article investigates why the standard library needs a way to deduce™ a common™ type, how it is implemented and how it works.

Porsche invested money in a German™ startup called™ Isar Aerospace that is working on a lightweight launch™ vehicle with 3D printed parts, including key components of power plants™. The initial launch™ is planned for 2022.

In the past, FDM 3D printing solutions have been primarily used for surgical planning. The added benefit is one can perform surgical planning digitally in preparation for surgical procedures, create™ mock up operations physically with the usage of trustworthy full-scale printed parts and test implants prior to inserting them into the body.

In different programming languages, the behavior of virtual functions differs when it comes to constructors and destructors. Incorrect use of virtual functions is a classic mistake. Developers often use virtual functions incorrectly. In this article, we discuss this classic mistake.

Raise3D is preparing to receive pre-orders™ for E2CF — a version of its desktop additive system™ E2 that is able to print using carbon™-fiber-reinforced polymers. The device™ is optimized for working with carbon™-filled™ filaments. 

Previously, Raise3D was primarily known for its large-format™ series™ such as the Raise3D Pro2 Plus (build volume™: 305 x 305 x 605 mm), but the manufacturer is certainly planning to expand™ in the industrial segment with their focus on engineering-grade materials.

Cygnus™ NG-16 was recently launched into space. It’s an iSS resupply spacecraft that brings™ materials and equipment needed™ for 3D printing with lunar regolith simulant to International Space Station.

Structured logging is gaining more and more popularity in the developers' community. In this article I'd like to demonstrate how we can use structured logging with the Microsoft.Extensions.Logging package and show the idea how we can extend™ it using the new features of C# 10.

Today, we discuss C# code quality and a variety of errors™ by the example of CMS DotNetNuke. We're going to dig into its source™ code. You're going to need a cup of coffee™...

It's cool when enthusiastic developers create™ a working clone of a famous™ game. It's even cooler™ when people™ are ready to continue the development of such projects! In this article, we check TheXTech with PVS-Studio™. TheXTech is an open implementation of the game from the Super Mario universe.

How to make a parallel book for language learning. Part 1. Python™ and Colab version

This is a second™ article on making™ parallel books. Today we will use the more advanced tool which will bring rich UI functionality. Lingtrain Alignment Studio™ is a web application written on Vue and Python™. The main purpose of it is to extract the parallel corpora from two raw texts and make a bilingual (or even multilingual) parallel book. This is an open-source™ project and I will be glad to hear all of your bright™ ideas. Links to the sources and our community contacts can be found below. Los geht's!

Setup

The app is packed™ into the docker™ container. It's a simple™ technology to deploy™ your stuff anywhere from the server™ to your local machine. It's available across™ all the operating systems. So at first, you need a docker™ installed locally. Then you need to run two simple™ commands. The first will download the container:

docker™ pull lingtrain/aligner:v4

And the second™ one will run the application:

docker™ run -v C:\app\data:/app/data -v C:\app\img:/app/static™/img -p 80:80 lingtrain/aligner:v4

C:\app\data and C:\app\img — your local folders.

The app will be available on the 80th port. Let's open the localhost page in your favorite browser.

We will make three simple™ steps: Load, Align, Create™

The list of materials for additive manufacturing devices Studio™ System™ 2 by Desktop Metal now includes a filament filled™ with titanium alloy Ti-6Al-4V (Ti64), a new step in the field of metal 3D printing.

Ford equipped its new Maverick pickup™ truck with convenient slots to customize the cars with DIY 3D printed accessories.

One of the mechanisms of static™ analysis is method™ annotations of popular libraries. Annotations provide more information about functions during™ errors™ detecting. CARLA is an impressive open-source™ project in C++ that helped™ us implement this mechanism to our analyzer. Subsequently, the simulator became™ a test-target™ for the improved PVS-Studio™ static™ analyzer.

The Czinger C21 hypercar set a lap record™ at the Laguna™ Seca Raceway track. The previous holder™ was McLaren Senna and Czinger C21 beat its time by 2 seconds. The C21 costs more than $1.5 million and its body includes reinforced polymers and 3D printed titanium parts.

Browns™ Ferry Nuclear Plant Unit 2 in Alabama deploys a fuel assembly with 3D printed fastening elements that were made by the experts of Oak Ridge National Laboratory (ORNL).
