The meetup on January 14 at Hacker Dojo in Mountain View, California, went well, although not as planned - we spent almost all the time talking instead of doing hands-on exercises. The room we booked can fit 30 people and approximately 30 people did show up. The quality of participants was high: approximately half were familiar with hardware description languages and another half came from various software topics. 12 people filled out the questionnaire despite the fact that I forgot to bring 30 pens.
The discussion during and after the presentation was focused and very meaningful: microarchitecture and education, EDA infrastructure / build scripts, open-source ASIC design tools, the economics of ASIC design and manufacturing, high-level synthesis, transaction-level modeling, ASIC prototyping using FPGA boards, FPGA embedded in ASIC (Menta), new FPGA manufacturers (Gowin) and new design languages - Chisel and SpinalHDL.
Four persons came to me after the meeting to discuss their participation in working on open-source portable SystemVerilog examples, and another seven expressed this intention in the questionnaire. So we are meeting again in Hacker Dojo on Sunday, January 21, at 2 PM, this time not in the classroom area, but in the common shared area.
Generally, I am thinking of having regular meetings, probably on a weekly basis for a small team of developers of the educational materials and on a monthly basis for a wider audience, discussing various design and verification topics.
There were two correspondents of Slavic Sacramento who recorded the video of the presentation. They are going to make it available soon.
The November commitfest is ripe with new interesting features! Without further ado, let's proceed with the review.

If you’re a React developer, you know how important state management is. State is the data that powers your UI, making it interactive and dynamic. But managing state in React can be tricky, especially when you have to share it across multiple components or deal with complex and asynchronous logic.
That’s why over the years, React developers have come up with various solutions for state management, each with its own advantages and disadvantages. In this article, we’ll take a look at some of the most popular ones and how they evolved. We’ll also review some of the current state-management libraries and how to choose the best one for your app.

UX testing is one of the most important parts of the UX design creation process for any software product. It helps to understand whether users are satisfied with the design and highlights its problematic areas that need to be fixed or improved. UX testing is an important part of the whole testing process - it helps to get beta-testers feedback to determine whether the product is comfortable for users and gives opportunity to improve problems and issues before moving on to the next stage of the development process. It also contributes to reducing the cost of development, as it is much cheaper to fix issues during the development process rather than after the release. Listed down below are 5 simple tips that can help perform UX testing in a proper and effective way.
