Monolith to microservices. Infrastructure point of view
I'd like to share my story about migration monolith application into microservices. Please, keep in mind that it was during 2012 — 2014. It is transcription of my presentation at dotnetconf(RU). I'm going to share a story about changing every part of the infrastructure.
Starting point
On the other hand, the benchmark in monetarism (Milton Friedman) and the Austrian School of Economics (Ludwig Heinrich Edler von Mises, Friedrich August von Hayek) is freedom. Economic and political freedom.
The third fashionable point at present is the concept of “The Happy Planet Index”.
Thus, there is no single point of reference.
Nevertheless, this point is easy enough to detect if you understand the basic principles of building a modern post-industrial democratic society. If you understand what is common in these models. Where is their common starting point.
The modern economic system, as well as the modern democratic system, were not created for themselves. They are made for people. And that means not a person for the state, but a state for a person. Laws are not to limit human freedoms, but to ensure respect for the rights and freedoms of each person, laws to increase the happiness and wealth of a person. Not GDP, but the wealth of each individual.
States are made up of people. No people — no state. Poor people are a poor state.
Wealth, happiness, human freedom — is the area of respect for his rights.
Thus, a common unifying point in economic and political reasoning and theories is in the field of human rights.
The Cake is a Lie
Have you ever thought — How to explain programming to the one never faced it before? It could be a problem, as long a new one will not understand you.
So, let's imagine — you have a friend, who is not soiled by computer science, never tried to automate something, never played factorio, never written a single line of code.
So, let's imagine a normal human being.
And let's call him Bill. He is not very good in Maths, just “not good”, but he loves candies!
Your task is to teach Bill some basic(or magic) IT things, you are doing every day. The simplest ones.
So what shall you do first? Basically — FEED HIM!
Product manager’s mastery. Feature requests
Feature prioritization is based on multiple principles. Basic are aligning to company vision, product strategy, and customer profile. For example, if you’re targeted to small businesses or home offices doing SAP integration request shouldn’t be in your first place.
But what share feature requests take in a product backlog? An answer like “it is full of customers' requests” isn’t correct. It seems strange but true.
If you’re not happy to read long texts the advice is “you should not give attention to customers' requests if your product is mature”.
How to test your own OS distribution
Let's imagine that you are developing software and hardware appliance. The appliance consists of custom OS distributive, upscale servers, a lot of business logic, as a result, it has to use real hardware. If you release broken appliance, your users will not be happy. How to do stable releases?
I'd like to share my story how we dealt with it.
My experience of advertising and development of Android and iOS application
Let me share an interesting experience in promotion of a mobile game.
1. Introduction
I am going to describe all the benefits and of course show the final results. The example will be the mobile game Quick Brain which is available for Android и iOS. Quick Brain Android was released the first that's why its possibilities differ considerably from iOS version.
I have been always kept by the thoughts that everyone's talking about high returns in contrast with Android. I just couldn't resist such attractive prospects and started more active refinement of iOS version in order to feel less embarrassed about it.
After Google play iOS has become an absolutely new field for the games for me. During my comparative experiment I've found out that iOS version can bring comparable earnings to Android with daily audience 3 to 10 times less depending on the country.
Full-stack developers are in fact stuck at mid-level. Spare yourself from suffering – don’t go down that path
Back in those times when I just started learning how to code, I trusted the old wise weasels with their “Programming languages don’t matter” mantra. I grew obsessed with the idea of some day becoming a developer who can do just anything. That guy who transfers his experience from one technology to another and transcends the minutia. But that idea failed miserably.
$10 million in investments and Wozniak's praise — creating an educational computer for children
In mid-October the Sistema_VC venture capital fund hosted a conference called Machine Teaching, where creators of various educational startups assembled to talk about technical advancements.
The special guest was Mark Pavluykosvkiy, the creator of Piper. His company created an educational computer — a children’s toy that, using wires, circuit boards and Minecraft teaches programming and engineering to children. A couple of years ago Mark completed a successful Kickstarter campaign, got a couple of Silicon Valley investors on board and raised around $11 million dollars in investments. Now he’s a member of Forbes’ “30 under 30” list, while his project is used by Satia Nadella and Steve Wozniak, among others.
Mark himself is a former Princeton and Oxford student. He was born in Ukraine, but moved to the US with his mother when he was a child. In various interviews Mark claimed that he doesn’t consider himself a genius, but simply someone who got very lucky. A lot of other people aren’t so lucky, however, and he considers it unfair. Driven by this notion, during his junior year he flew to Africa, where he almost died.
Startups’ mistakes and pitfalls at patenting their IP
Nuts and bolts
Patent is a document of title to:
• the exclusive right to,
• authorship and
• priority of an —
— invention,
— utility model, or
— industrial design.
Invention, in its essence, is a technical solution expressed in the combination of essential features — that are sufficient for achieving the technical result.
Essential features are those affecting the achievability of the technical result — or, in other words, are in a cause-and-effect relation with the result.
Technical result is a trait of the technical effect, event, property, etc. that effectively appear in the exercise of the method, or in the production or use of the product, including in the use of the product produced directly by the method, of invention.
Patent claim defines the scope of protection of the patent, as it comprises the combination of essential features — that are sufficient for achieving the technical result.
Error 1 — The lack of protection
Peter created an ingenious algorithm; there are no known analogues to that whatsoever. He fiercely codes a prototype and begins the commercialisation in Russia. He puts up a website, uploads a demo, does some exhibitions. Gains momentum and taps into the US market. And here we go…
Automation VS Chaos
IT technologies evolution allowed to control huge data flows. Business has a lot of IT solutions: CRM, ERP, BPM, accounting systems or at least just Excel and Word. Companies are different too. Some of companies are composed of plenty branches. Let’s name such as “Pyramid”. Pyramids have data synchronization issue for pile of IT systems. Software vendors and versions differ for branches significantly. In addition management company continuously modify reporting requirements that causes frustration assaults in the branches. This is a story about the project I happened to encounter chaos that needed to be systematized and automated. Low budget and tight deadlines limited the use of most existing industrial solutions but opened up scope for creativity.
Content Marketing in Popular Online Media: 5 Mistakes of Startups to Avoid
I actively help companies from all over the world to prepare promotional content for English language resources. Today we will talk about common mistakes that are made by startups when working in this area and the erroneous expectations of their directors.
What to think during NALSD interview
So, what is the difference? How to be prepared for this interview? Let’s be non-abstract, and use an example. To be more non-abstract, let’s take something from the material world, such that you won’t be asked the exact same thing at the real interview (at least, not at the Google interview) :)
So, let’s design a public library system. For the paper books, like you have seen everywhere around. The whole text below was written all at once within around one hour, to roughly show you the areas that you should be able to cover / touch during the interview. Please excuse some disorder, that’s how I think (therefore I am).
How to milk cows with robots and make an industrial startup of it. The history of the R-SEPT development
In 2017, the media heard a very interesting story about a startup that robotizes milking cows on industrial dairy farms. The company is called R-SEPT, and back then it received 10 million rubles of investment. But a year has passed, and there's still no news on what happened further. We contacted Aleksey Khakhunov (AlexeiHahunov), the founder of the startup, and discussed the development. It turns out that the whole year his team was getting the prototype of the robot into shape, and just a week ago they conducted their first field test on the farm.
Under the cut there's a story about a robotics student who grew up on his parents' farm, turned the University diploma into an industrial startup, as he collected the first manipulators with his friends, and then scaled up to the level of state programs for the robotization of agriculture. And the most important is how the iron hand of the robot and the machine vision are better than a living milkmaid.
Как спланировать двухнедельный спринт
Иногда молодые команды разработки охватывает неразбериха.
Это случается в тот момент, когда они ещё не до конца разобрались, что такое эджайл; проджект и продакт спорят, кто из них кто, а задачи каждый ведёт сам по себе. Или все уже всё знают, но планировать спринты не получается — задачи не прорабатываются, демо и ретро проходят нерегулярно.
У нас тоже была похожая история, но мы нашли свой путь.
Это рассказ от команды личного кабинета Яндекс.Кассы, и подробнейшая инструкция для тех, кто хочет улучшить своё планирование.
Как всё было
