Last week I was doing a seminar on SystemVerilog, ASIC and FPGA at ADA University in Baku, Azerbaijan. I will replicate the last two sessions of this seminar, on RISC-V CPU simulation and synthesis, at the Verilog Meetups on March 3 and March 10 at Hacker Dojo, Mountain View, California. For this reason I am combining the information about Azerbaijan and California seminars in a single post.
First, let's talk about ADA University.

The rapid exploration of outer space has faced a problem related to the insufficient efficiency of modern rocket engines. As a solution to this problem, the concept of a jet engine based on new operating principles is proposed, using a combination of known physical laws and having advantages over known types of jet engines.The article presents the results of testing three modifications of jet engines based on new operating principles and their analysis. The article discusses the physical principles of operation of a jet engine based on new principles, its advantages and problems arising during its creation.
The team developing a set of portable SystemVerilog examples decided to organize the first event in Silicon Valley on Sunday, January 14 from 2PM till 5PM at Hacker Dojo in Mountain View, CA. If the first event is successful we are going to make it recurrent. You can register for the event on Meetup or LinkedIn.
The current directions of the group:

Understanding valid/ready protocol is extremely important for every microarchitect.
Valid/ready is one of the main protocols used to organise flow-control inside a logic block as well as on inter-block (SoC) level.
In the last lesson, we explored FIFO buffer using hdlgadgets - human-in-the-loop HDL training tool.
This time we will take two FIFO buffers (which form a pipeline with valid/ready handshakes) and will experiment with it by changing flow-control logic of the pipeline.
We will show that valid/ready is not only a mechanism for transferring data from one FIFO queue to another, but also a method for organizing various kinds of logical functionality between queues.
If you have not worked with valid/ready protocol before, you will be surprised how easy it is to achieve desired functionality of the design by simply writing couple of lines of Verilog code in the handshaking logic block between two FIFOs.
OpenTeleletry Collector is an open source data collection pipeline that allows you to monitor CPU, RAM, disk, network metrics, and many more.
Collector itself does not include built-in storage or analysis capabilities, but you can export the data to Uptrace and ClickHouse, using them as a replacement for Grafana and Prometheus.
When compared to Prometheus, ClickHouse can offer small on-disk data size and better query performance when analyzing millions of timeseries.
Rust's type system is quite powerful as it allows to encode complex relationships between user-defined types using recursive rules that are automatically applied by the compiler. Idea behind this post is to use some of those rules to encode properties of our domain. Here we take a look at Peano axioms defined for natural numbers and try to derive some of them using traits, trait bounds and recursive impl blocks. We want to make the compiler work for us by verifying facts about our domain, so that we could invoke the compiler to check whether a particular statement holds or not. Our end goal is to encode natural numbers as types and their relationships as traits such that only valid relationships would compile. (e.g. in case we define types for 1 and 3 and relationship of less than, 1 < 3 should compile but 3 < 1 shouldn't, that all would be encoded using Rust's language syntax of course)
Let's define some natural numbers on the type level first.

With the end of the 2022' third quarter, we invite you to take a tour into DDoS attacks mitigation and BGP incidents statistics recorded from July to September.
It feels like everything about LPs has already been said, however, I still keep seeing the same mistakes being made over and over again both by start-ups and established companies. Here are some tips, backed up by my 10-year experience as a UX/UI Director in agencies and product-led companies. These alone will give a nice increase in your conversion rate, I guarantee.
Use a descriptive, not a salesy hero header
Answer the questions “What?” and “For whom?” as early on the page as possible. A very common pattern is the largest copy being an inspirational abstract slogan and below it in smaller font the actual statement about what the product is and what it does.
The second quarter of the year has ended and, as usual, we take a look back at the mitigated DDoS attacks activity and BGP incidents that occurred between April and June 2022.
Once again, we are going to talk not about familiar desktop CNC machines such as the Flux BeamBox 40W but about large industrial equipment.
The Kolomna Locomotive Works of Transmashholding put into operation a line for the manufacture of diesel engine fuel equipment. The machining centers and CNC machines of the new line will increase the production of parts by 40% and improve the quality of products. Precision fuel equipment is the most complex component of a diesel engine, which directly affects fuel consumption, environmental friendliness, and performance of the machine, as well as its service life.
The new equipment will increase processing accuracy and speed, reduce the number of finishing operations, and increase labor productivity. The production line consists of 24 units of high-precision equipment: machining centers and versatile CNC machines. The costs amounted to 2 billion rubles (about $26,280,000).
The program for the production modernization and the introduction of new equipment was developed by the engine-building center of Transmashholding.
The total volume of the investment program for 2018–2022 is about 12 billion rubles (~$157,720,000). Its implementation should ensure an increase in the quality of existing products, a decrease in production costs, and the creation of new competitive products.
Dmitry Mirny, CEO of the Kolomna Locomotive Works, stated, “We have purchased modern high-tech equipment that will allow the factory to accelerate the process of production modernization, increase production volumes, and speed up diesel engine repairs.”
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.
So, I finally found a moment to write a bit about how we created the water for TReload. Our basic goal was to flood all of the levels with acid - a lot of acid, as the flooded area is massive :) Here’s one of the results which we got out of this process:
Grind is a process of slowly getting valuable resources (be it experience points or loot) by repetitive and often simple tasks in video games. It has been present from the beginning of gaming but has become more widespread with the popularization of online RPG games because of their leveling systems and competitive elements.
It is highly criticized by gamers around the world for making games boring and work-like, yet many people specifically choose to play grind-heavy games. The reason might be because they find simple repetitive tasks relaxing and distracting from real-life problems, as a form of escapism.
However, there is also a gameplay reason for grinding: getting valuable resources early can make a game easier later. Some popular games like Diablo are even centered around grind. Thus, everyone will have to grind at some point to prevent gameplay from getting too difficult, which quickly becomes an inescapable habit. Later, gamers might apply grinding even to games that do not require it. Interestingly enough, grinding early on can also make the late-game boring because it is going to be too easy if the game was not designed for grinding. For example, in Subnautica, getting a lot of resources early on will make some of the late-game tools useless because all the resources that could have been gained with them have already been gained.
From the example above, we can see that grind does not always improve the gameplay. We can also see that it is not always a necessary process and can be either minimized or avoided entirely: sometimes, the need for it exists only in our mind, forcing us to diminish the fun of actually playing the game. Is it just a question of habit or is there any other reason for us to grind?
After 210 days, 600 commits, tens of debugging nights, and thousands of messages in the project chat, I finally released AngouriMath 1.2.
This is an open-source symbolic algebra library for C# and F#, maybe it is interesting for someone?
Recently we found out that the new version of the fheroes2 project was released. In our company there are many fans of Heroes of Might and Magic game series. So, we couldn't pass it up and checked the project by PVS-Studio.
