 ----------------------------------------------------------------------

Today i took a ride with a time machine. Back to autumn last year where i started to learn programming in python. I made revision of python knowledge. Nearly whole day i was reading a book „Automate boring stuff with python” by Al Sweigart publish by No Starch press(known to publish another great book „Eloquent JavaScript” by Marijin Haverbeke.)


Decied to cover whole book and improve python skills. My first experience with algorithm exercises and solving cs problems was done with python. Mainly i was using HackerRank.com service with great unit tests written for each and every task.


Math operators, assignment operators, control flow statements such as if/elif/else conditional statements. While and for loops with continue and break instructions. Function definitions and signatures. Basic data structures – string, boolean, number, float. Copying primitive data structures. Complex data structures. Lists, tuples, dictionaries. Referencing complex data structures. Mutability of dictionaries and lists and immutability of primitivies. .copy and .deepcopy methods of copy modules. Importing the libraries and using imported tools were among studied terms.


I discovered some analogies to javascript tools. Linter for python scripts is called pyLance, basic package manager name for python is pip. I have reached the beginings of books second part on automation of repetitive tasks. It was huge chunk of information about regex. Python regex is very similar to the one that is part of javascript. The library for regex in python is called re(regular-expressions). Main re library methods: .compile .search .findall .group .sub(). There are additional compile method arguments such as re.IGNORECASE(u flag), re.DOTALL, re.VERBOSE that contain aditional options for regular expresions.


Finally the good news is that I found idea of a new project to put in my portfolio and i believe improve it a bit. During the troubleshooting of my laptop keyboard i found out a useful webapp. It was a test suite for keybords. Using it I got to know that malfunctioning of the device isnt caused by mechanichal issue but rather one connected with drivers. In upcoming days I will be definetly working on my own version of keyboard tester react app. Hope it will be a success.

  fig 1.1 BehaviorSubject abstraction marble diagram       It is high time to write another part of angular basics revision. Last time i mentioned Subject object. It is also worth to describe other ‚special’ cases of Subject. The first is behavior subject. It is part of powerful tool for reactive programming called rxjs . When writing angular version of exchange app or mars-rover-photos app I was using behavior subject in following way. Start with declaring behavioral subject private field within your service. The following example ilustrates this step: private myDataSubject: BehaviorSubject<any> = new BehaviorSubject<any>( null );     it will declare new private field with myDataSubject name and BehaviorSubject type. The value within <> braces is called type parameter and is a part of TypeScript generic types. In this case it would describe the type of values emited by this subject. on the right side of the assignment statement we can see basic javas

Another subject from the set of 97 things that every programer should know is simplicity. The most important thing designing software is to provide client with the functionality tailored to their real needs. Managers dont care about tools applied to obtain requested outcome as long as it gets the job done quickly and satisfy the requieements. On the other hand developers mostly need challenge and constant growth. As a consequence nowadays applications tend to be over-engineered and stuffed with additional libraries, frameworks with tons of configuration. Today ive also watched a youtube video of primagean. It was a comment on article titled "Radical simplicity". It is a reason why id written previous paragraph. The article was about technical overhead that is tend to be introduced within the aplications recently. The one good thought was that nowadays applications are able to do more stuff. The main thought was to use the bare minimum and be careful about introducing new d

fig 1.1 angular application structure overview      Recently I have been re-writing one of my side projects using another js framework. Originaly written in react, after several days and long hours of scrolling and prompting it was re-shaped to Angular version . In this blog post I want to summarize the stuff I have learned about javascript frontend framework developed by Google . There are only class components. No function component nor hooks available in angular. Moreover it requires developer to use typescript straightaway without support for vanillla js which make it less available for beginners. Angular has no dedicated syntax such as jsx/tsx which enables to combine template, controller and styles within single file. It divides the responsibilities to separate view-template.html file and component.ts file which contains logic. It is a good moment to mention that re-renders of the ui uses diferent technique under the hood. Angular utilizes incremental DOM mechanism a
