In the previous article we refreshed our memory of WebRTC CDN and the ways this technology helps to minimize latency for WebRTC streams. We also discussed why load balancing and autoscaling wouldn't be amiss in CDNs. Here are the main points from the article:

Automatize it, or Docker container delivery for WebRTC
The vast majority of IT specialists in various fields strive to perform manually as few actions as possible. I won't be afraid of the loud words: what can be automatized, must be automatized!
Let's imagine a situation: you need to deploy a lot of servers of the same type and do it quickly. Quickly deploy, quickly undeploy. For example, to deploy test rigs for developers. When development is carried out in parallel, you may need to separate the developers, so they don't impede each other and possible errors of one of them don't block the work of the others.
There may be several ways to solve this problem:

The idea to build a 4th order low-pass filter looks simple: add one more feedback loop. But there are pitfalls, as always.
How to choose the appropriate level of statistical significance for an AB-test
![](https://webcf.waybackmachine.org/web/20210624042944im_/https://habrastorage.org/getpro/habr/upload_files/25c/7b6/327/25c7b63270c491bd40ecea91f1c825cf.png)
Nowadays a lot of product managers have to confirm most of their decisions with AB-tests. Yet, it is far not always clear how to choose the parameters for the test. A particularly difficult parameter to tune is often the level of statistical significance. If we choose too high level - tests will fail even though improvements do exist. If we choose too low level - we'll be getting lots of "confirmations" of false improvements.
When we make decisions based on AB-tests, once in a while we'll be making mistakes. We can limit the losses caused by such mistakes by choosing the appropriate level of statistical significance.

12 Tech Trends Every Java Developer Must Learn To Win The Game In 2021
![](https://webcf.waybackmachine.org/web/20210624042944im_/https://habrastorage.org/getpro/habr/upload_files/325/351/f3a/325351f3aafa92e2e2d755755bcb391d.png)
The previous year has been very distressing for businesses and employees. Though, software development didn’t get so much affected and is still thriving. While tech expansion is continuing, Java development is also going under significant transformation.
The arrival of new concepts and technologies has imposed a question mark on the potential of Java developers. From wearable applications to AI solutions, Java usage is a matter of concern for peers.
Moreover, it is high time that developers enhance their skills as to the changing demands of the industry. If you are a Java developer, surely you too would be wondering what I am talking about what things you should learn.
Blockchain is the perfect solution to online privacy problem
![](https://webcf.waybackmachine.org/web/20210624042944im_/https://habrastorage.org/getpro/habr/upload_files/38e/a01/b29/38ea01b29d227087104b30cc14c6b19f.jpg)
We are increasingly aware of the importance of our personal data. Primarily due to numerous data leaks and the fact of numerous sales of personal information on the black market. Yes, huge corporations like Apple or Samsung prioritize the preservation of sensitive user data. However, they find it difficult to store and use them at the same time. That is why blockchain technology is the perfect tool for solving the online privacy problem.
There are constant news in the media about the problem of personal privacy, which is represented by constant data leaks and the general technological illiteracy of the world population. In the Pew study, nearly 80% of respondents said they are very concerned about how companies are using the data they collect. In MState's study, 24% of respondents stopped using certain apps due to privacy concerns.
Today, an increasing number of people are actively protecting their data by refusing the services of companies and applications that use personal data. This is why Apple, Lyft, Dropbox, and Adobe have started taking a consumer-centric approach to data privacy. Consumers' understanding that their personal data is a commodity is increasing.
Free TON is a prime example of a secure blockchain. This blockchain has some of the best features compared to Ethereum, Binance Smart Chain, and Stellar. Data security directly depends on the use of blockchain. Each of the above blockchains provides a different level of data protection. Ethereum is the most popular blockchain, but Free TON may soon overtake it. This blockchain is just over a year old, and its capabilities exceed those of all other blockchains.
Telegram bot provides time-based currency

Many of us spend time in specialized telegram groups. The power over communication here belongs to random people with their own shortcomings. Conflict and abuse occurs regularly. Is there another way to keep order so that scam spam doesn't flourish and no one has total control over group members?
In my case, these thoughts led to the development and testing of a system that can be connected to your Telegram today.

And so here we find ourselves in the year of our lord 2021. Global crypto market capitalization is approaching $2 trillion. PayPal is launching a crypto checkout service. Lindsay Lohan is shilling Tron. The Dogecoin Super Bowl commercial didn’t happen, but Elon’s taking it “literally” to the moon instead. Our ascendancy is complete. Crypto is mainstream. But, even today, getting your hands on certain crypto assets can be a bit of an epic journey.

Neural network Telegram bot with StyleGAN and GPT-2
The Beginning
So we have already played with different neural networks. Cursed image generation using GANs, deep texts from GPT-2 — we have seen it all.
This time I wanted to create a neural entity that would act like a beauty blogger. This meant it would have to post pictures like Instagram influencers do and generate the same kind of narcissistic texts. \
Initially I planned to post the neural content on Instagram but using the Facebook Graph API which is needed to go beyond read-only was too painful for me. So I reverted to Telegram which is one of my favorite social products overall.
The name of the entity/channel (Aida Enelpi) is a bad neural-oriented pun mostly generated by the bot itself.

Algorithms in Go: Bit Manipulation
This article is a part of Algorithms in Go series where we discuss common algorithmic problems and their solution patterns.
In this edition, we take a closer look at bit manipulations. Bit operations can be extremely powerful and useful in an entire class of algorithmic problems, including problems that at first glance does not have to do anything with bits.
Let's consider the following problem: six friends meet in the bar and decide who pays for the next round. They would like to select a random person among them for that. How can they do a random selection using only a single coin?
The solution to this problem is not particularly obvious (for me:), so let's simplify a problem for a moment to develop our understanding. How would we do the selection if there were only three friends? In other words, how would we "mimic" a three-sided coin with a two-sided coin?
Distributed Artificial Intelligence with InterSystems IRIS
Author: Sergey Lukyanchikov, Sales Engineer at InterSystems
What is Distributed Artificial Intelligence (DAI)?
Attempts to find a “bullet-proof” definition have not produced result: it seems like the term is slightly “ahead of time”. Still, we can analyze semantically the term itself – deriving that distributed artificial intelligence is the same AI (see our effort to suggest an “applied” definition) though partitioned across several computers that are not clustered together (neither data-wise, nor via applications, not by providing access to particular computers in principle). I.e., ideally, distributed artificial intelligence should be arranged in such a way that none of the computers participating in that “distribution” have direct access to data nor applications of another computer: the only alternative becomes transmission of data samples and executable scripts via “transparent” messaging. Any deviations from that ideal should lead to an advent of “partially distributed artificial intelligence” – an example being distributed data with a central application server. Or its inverse. One way or the other, we obtain as a result a set of “federated” models (i.e., either models trained each on their own data sources, or each trained by their own algorithms, or “both at once”).
Distributed AI scenarios “for the masses”
We will not be discussing edge computations, confidential data operators, scattered mobile searches, or similar fascinating yet not the most consciously and wide-applied (not at this moment) scenarios. We will be much “closer to life” if, for instance, we consider the following scenario (its detailed demo can and should be watched here): a company runs a production-level AI/ML solution, the quality of its functioning is being systematically checked by an external data scientist (i.e., an expert that is not an employee of the company). For a number of reasons, the company cannot grant the data scientist access to the solution but it can send him a sample of records from a required table following a schedule or a particular event (for example, termination of a training session for one or several models by the solution). With that we assume, that the data scientist owns some version of the AI/ML mechanisms already integrated in the production-level solution that the company is running – and it is likely that they are being developed, improved, and adapted to concrete use cases of that concrete company, by the data scientist himself. Deployment of those mechanisms into the running solution, monitoring of their functioning, and other lifecycle aspects are being handled by a data engineer (the company employee).
High-Quality Text-to-Speech Made Accessible, Simple and Fast
There is a lot of commotion in text-to-speech now. There is a great variety of toolkits, a plethora of commercial APIs from GAFA companies (based both on new and older technologies). There are also a lot of Silicon Valley startups trying to ship products akin to "deep fakes" in speech.
But despite all this ruckus we have not yet seen open solutions that would fulfill all of these criteria:
- Naturally sounding speech;
- A large library of voices in many languages;
- Support for
16kHz
and8kHz
out of the box; - No GPUs / ML engineering team / training required;
- Unique voices not infringing upon third-party licenses;
- High throughput on slow hardware. Decent performance on one CPU thread;
- Minimalism and lack of dependencies. One-line usage, no builds or coding in C++ required;
- Positioned as a solution, not yet another toolkit / compilation of models developed by other people;
- Not affiliated by any means with ecosystems of Google / Yandex / Sberbank;
We decided to share our open non-commercial solution that fits all of these criteria with the community. Since we have published the whole pipeline we do not focus much on cherry picked examples and we encourage you to visit our project GitHub repo to test our TTS for yourself.
