How to achieve concurrency and parallelism in Ruby? There are a couple of ways and I will describe these in the following article. It only covers the usage of Ruby core and standard library modules.
Modern CPUs consist of multiple cores, so software developers can benefit. Nowadays programming languages with concurrency features support the usage of multi-cores. Ruby is no exception, let's see how this it could be done.

There is a ton of materials on Domain-Driven Design. There are books, lectures, videos. But how to put all those concepts in code? Take a look if you'd like to see an example DDD application in Ruby on Rails.

As some of you may know, around 1,5 years ago I made a decision to pass my responsibilities as CEO to Michał Krochecki and Mariusz Kozieł. Since that time I’m slowly withdrawing my engagement in day to day business at Visuality - which gives me a lot of free time. This is the story of how we launched a successfull startup - Poltrax.

Working in a software house means changing projects from time to time. Usually, I have to use a separate git account for a new project. But I don't want to delete my original account, rather I'd like to have both. It's easy to solve, but surprisingly I see many people have problems with it. Here's the solution.

Aggregate - in Domain-Driven Design means much more than just a collection. It's a guardian of the state and a validator of rules. It's the key element to any domain model. We are taking a deep dive into DDD aggregates in the context of Ruby on Rails framework.

Callbacks are methods that are called at specified moments of an object's life. They allow us to easily add new functionalities linked to the object's lifecycle but also can cause some troubles. In this post, we will describe some of the potential issues, that using callbacks can cause.

The conditional operator in Ruby is commonly used but is also a bit misperceived. In this post, we will search for the most accurate approximation, of what `||=` really does, and use that occasion to revisit some of Ruby's concepts.

Preserving data quality is always a challenge. Especially in the Ruby on Rails world where products ship fast. It means some compromises are made along the way and often data quality is sacrificed. And when it comes to data - it's better to prevent than cure.

At the beginning of last year, I decided to introduce meetings where engineers could share knowledge. As Visuality is most about Ruby we name them backend meetings. There were so many topics to discuss which didn't have a place to be faced. Let me summarize my thoughts.

After the covid break and a bunch of online conferences, we finally had a chance to attend one physically. "I love dev" took place in Złote Tarasy (Warsaw, Poland) on the 17th of May and was certainly the biggest software development-related event in 2022 so far. Let us share what it was about.

Since the last blog post about recruitment was written three years ago, our approach to quality hasn’t changed (we still treat it as the highest priority). But we gained some additional experience regarding recruitment - feedback from candidates suggested that our previous process was a little too long and complicated. Of course, we also accommodated pandemics and allowed remote recruitment meetings. As a result, we have a more flexible, shorter, and consistent recruitment process. Let me describe it.

I decided to break my radio silence again. I’ve just written an article about our 13th birthday and figured out I feel creative enough to write another one. I wanted to choose something that would be valuable to our clients and interesting to others as well. Hence the topic “how to approach funding as an MVP”.

Some time ago I started to notice that quality as a term comes out increasingly often as a buzzword in sales conversations and negotiations. When it comes down to selecting a tech partner, it is important to consider their strengths and their competitive strategy. Naturally, as a result of political and economical factors, the CEE region has strong ties with Western Europe capital and business and thus functions as a subcontractor.

The COVID-19 pandemic has thoroughly changed the way we live, work, and, yes, hire people. Modern HR tech solutions aid recruiters, help manage work and organize cooperation in the new remote setup. We’ve decided to take a closer look at HR tech software development and indicated five crucial trends in HR systems and platforms that will shape this sector in 2021. Let’s get right to it!

I’ve been running Visuality software house for 13 years now and during this time I’ve interacted with a lot of founders and discussed their businesses. In time, the knowledge I’ve gained became more and more statistically significant and there is one thing I’d like to address - code quality & engineering approach in software development.

My previous blog post highlighted the history behind 360 review in Visuality. And as I told you then, designing a new 360 review process was one of the first challenges I’ve taken care of after joining Visuality forces. I’ve learned about the first "why" behind the process, how it was introduced to the organization — it shows me the grounds of the current shape. With that perspective, I was ready to discuss with Michał current obstacles.

When I joined Visuality in June 2020 as Wellbeing Manager, one of the first challenges Michał (CEO) put on the table was “New 360 review process”. As a psychologist and former researcher I asked a standard, but golden question you’ve probably already guessed: “Why, Michał?”. And we started talking.
This story is going to be written in two parts — in order to tell you about our current 360 review process, I’d like to tell you how it looked in the past and what challenges Visuality was facing. Thanks to that, you’ll see — or at least it’s my intention — how some obstacles might be solved and what’s the rationale behind the current solution.

Funny how things work out. One year ago I was telling every candidate that we are office-first company that accepts occasional remote work. In just few months we were forced to switch to remote-first company - probably like most of you. In this article I’d like to share some insights about how this situation influenced our culture, and what is surprising, how it made us realise truly what our culture actually is.

We use thermal printers daily like on **restaurants**, **shops** or **kiosks**, basically everywhere. Instead of using lots of different applications to print the receipt/ticket, it is nice to have just one application which can allow modifying styling too. WebUSB allowed us to connect this wide usage device to the webpages in any Chrome/Firefox without requiring any installation!

Due to the quality of the print, speed, and technological advances, thermal printers have become increasingly popular. These printers are widely used in supermarkets, libraries, restaurants, bars, transport industry, lottery and betting, kiosks, petroleum stations, etc. These are just a few broad examples of the usage of thermal printers. But what are the protocols to print images and text from thermal printers?

When playing board games, I always try to improve my performance and find some clever way to beat my opponents. I love analysing, discussing and recalling past games to find the most useful strategy and see things that are not seen by other players. This allowed me to form a few simple rules that increase chances of victory — not only in board games but also in real-life activities.

Deepening knowledge of the company's employees is the key to let them develop themselves and keep them in good mental condition. There are a couple of ways to provide them with it. Of course, an interesting and challenging project should be a major factor, as most of the developers' time is consumed there. Giving them an opportunity to take part in side projects, for example, via hackathons is also a great way to explore new areas.
Another great idea to expand their horizons is just to let your employees share knowledge between themselves. Here comes a fairly easy way to make it work, which is Lightning Talks!

As a full-stack boutique software house, we often deal with experienced clients that found themselves in many different situations regarding hiring or managing developers in their projects. For some, it has always been effortless and lucky, but for others, it has been a neverending nightmare and a long list of failures before they found us.

When it comes to train travel, there is one major player in Poland - the company called PKP Intercity which is also a national carrier. Unfortunately, I don't know anyone who see no flaws in PKP Intercity website and use it effortlessly. But I know a lot of people in all ages who'd rather go to the station and buy a ticket face-to-face only to avoid using this site. As it is carrier supported by the government, it should be user friendly, so… what exactly goes wrong? This is always a tough question.

Ruby is a beautiful language to work with. It provides tons of amenities for developers.
Like every other language, though, Ruby has things that you may not be aware of, or may not fully understand — and these quirks are the subject of today's blog post.

Software Developers and Project Managers. Do they play for the same team? They work in the same companies, work on common projects, but do they really always share the work, or do they sometimes fight each other for no good? Well, it depends. Mainly depends on the side that you’re looking from.

Uncertainty is an inseparable part of creating any software. At the beginning of the project you never have a full knowledge about future requirements and features. Developers don’t know the whole specification, project manager doesn’t know all clients’s expectations and usually clients are not aware about all features their product should have. When the amount of unspecified requirements is significant, choosing to create a prototype could be really beneficial.

Two years ago we introduced Docker to our company. One of our projects was complex in terms of deployment architecture and scalability. We were looking for a solution which allows us to simplify the process of deployment and scaling client's instances in the future. Docker turned out as a very good tool to isolate apps into containers with all needed dependencies and treat them as block boxes. Read this article to find out more!

Almost each company has its own logotype which is the main element allowing to distinguish the business from the competitors. The logotype is a recognizable mark which very often, in some symbolic way, presents the values of the business. But we need to remember that this is one of the many aspects of branding which influences brand awareness.

Not Invented Here Syndrome is the tendency of organizations to reject suitable existing solutions in favor of internally-developed ones. The result of this is often wasting hours on reinventing the wheel. In many projects, one the first important architectural decision is the API design. Given the gravity of this decision, countless meetings and discussions are held over the topic of what convention and formatting to adopt and almost always there are as many opinions as there are developers. What if there existed a ready-made solution?

So far we've been introduced with a couple of preprocessors like Less, SASS, Stylus and a lot of tools and methods for composing, organizing and managing stylesheets for our modern web applications.

Each day when we get up we come across dozens or even hundreds of products, services or brands which compete against each other for our attention. When we just open our eyes we are bombarded with company logotypes, colourful and beautiful packages or sophisticated shapes. Very often we even don’t realize how many commercial stimuli come act on us. Think – how many logotypes can you notice just after getting up? A logo on a toothpaste, toothbrush, shower gel, shampoo, hair dryer, t-shirt...and this is only the beginning!

As we're approaching the end of the year 2017, we may think about an upcoming year. Many of us will look back on the current year and think about all the things they wanted to do, but never managed to. Than some of us will label this as "New Year's resolutions" and will plan to fulfil them in 2018. We look at them with hope and determination.
Most of them will never be done anyway or will be abandoned shortly, because thinking about a task and writing it down is usually not enough. We encounter similar situation in software development, when we impulsively add a new task to the scope as a #TODO.

Few days ago Tobias Pfeiffer came to Visuality and gave a really great talk about clean code. While listening to him I realised, how important it is to us and how it influences our clients. Code quality has always been a big thing in Visuality so its always nice to hear somebody else confirm what we do everyday here:)

Christmas makes us think of friends. And in Visuality friends make us think of our garden, where in warmer months we use to invite them for merry gatherings. Alas it was winter, and our garden stood cold and desolate.
So our IoT club decided to light up the atmosphere and invite people to the garden anyway - virtually.
