In the heart of software development, in the city Brno, we launched a blog about IT.
I use Google a lot in my job. Not only to search things I don't know, but also things I should know very well. For a long time, I didn't feel good about it. Until, I read this stream of confessions from skilled senior developers on the Twitter. As a developer interested in graphics, I should know that using references isn't bad. Graphics use references all the time and they don't feel bad about it. In fact, it is advised to use them. The final result is what matters.
My question targets not only desktop software but also mobile apps, web applications, and websites. Seems like software is getting worse and it won't be better. And I just have to start my rumble with the worst - mobile apps.
Sooner or later it is inevitable to secure your database. At least in my opinion... It was the first time I was securing a MongoDB instance and when I was looking for some information I came across this blog post. At first, if you want to set up username&password authentication for your MongoDB instance, you will find the article really helpful. Secondly, you can take much more from the post...specifically almost 600TB of data from all around the world (if you wish of course).
I just recently saw someone joking about Scrum on the Twitter. He wasn't very fond of Scrum because by his own words, "What kind of methodology is it, when it needs a single dedicated person to enforce it?" We are talking about Scrum Master role here. I'm having many problems with this statement.
I was wondering since I am in a business and since I am in an IT, why these two sectors were seen separately for such a long time. It seems last few years people started realising they can work together. Nowadays, they are many companies based simply on the digital products, look at Airbnb, Uber, Google, Spotify.. without the technology and some algorithms plus great programmers they are nothing.
Let's face the Continuous Integration the development practice that requires developers to integrate code into a shared repository at least once a day per developer. Each check-in is then verified by an automated build, allowing teams to detect problems early.
My two favorite topics just next to the technology are food and design. I love both and I think about both of them most of the time. Therefore, a question appeared in my head: "Does Agile works just for software development or is it a way of workflow management also in any other areas we will choose?"
When you work for sometime on a larger project, you may realize it doesn't perform as well as it did. That is usually expected but sometimes, it just doesn't feel justified. This was also our case and because the performance of the project was important, we had to get our hands dirty with profilers and debuggers. Of course, we found a few bottlenecks.
I used to have startup developing a mobile application. We were two people working hard and at some point successfully, even though we were a big mess. Both of us doing things from design, to coding, to management, to marketing to planning everything needed. Yes, it is a typical startup mess, that we loved.
If you work in FinTech, sooner or later (but probably sooner) SAS data set will get into your project. In a field dominated by one system, there is hardly a place for rejection. Unfortunately, for small companies it is very hard to integrate SAS in their stack. In our projects, we use ETL to gather data from different sources. To be more precise, we use open source tool Pentaho Data Integration.
When we started using MongoDB in our projects, I was very confused by aggregations. But I wrote so many of them at this point, I actually enjoy putting them together. At least I enjoy it more than writing SQL queries. Yet there is one thing I have to process for a while in my mind every time - how to do null checking and field existence checking.
Having a pet project - a project being developed in your free time - can be a lot of fun. Give me a free week and option between spending the whole time on the beach or the possibility to work on my stuff, I will probably take #2. Don't get me wrong, who doesn't like a vacation? But when as the idle time raises, I'm getting bored and the itch to work on my pet projects grows.
