There is a Russian Broker — Tinkoff Bank. Now here is the problem: the broker doesn't support take profit and stop loss orders. At all. If you want to feel more convenient while trading, then you need some workaround for this situation, until Tinkoff Bank developers finally release those orders as the killer feature. In the article, I will show you my workaround.
update:2019-03-22, the Broker published platform 3.0.0 (a major update) in Google Play. The changelog features take profit/stop loss orders

Structures comparing

Sometimes you want to compare complex structures in tests ignoring some values. Usually, it can be done by comparing particular values with the structure:

This is how Alex Viscreanu’s talk on Moscow Python Conf++ named. Now it's two weeks till before the conference, but of course, I've already heard what Alex will speak about. Find below some spoilers and talk preparing backstage: what kind of an open source Zoo developed in Kiwi, how it tests Python code and what’s the difference between The Zoo and for example mypy.

— Tell us a bit about Kiwi, yourself and what is your work within a company?

Kiwi.com is an online travel agency based in Czech Republic. We aim to make travelling as simple and accessible as possible. The company was founded in 2012 as Skypicker, and since then it has become one of the five biggest online sellers of airline tickets in Europe. It was renamed to Kiwi.com in 2016.

The special feature that we, at Kiwi.com, offer is the virtual interlining, which allows us to connect flights from companies that don’t usually cooperate together, and we are covering the possible connection issues caused by delayed flights.

Some of the numbers that we manage at Kiwi.com include 90 000 000+ daily searches, 25 000 seats sold daily, and a total of 15 000 000 000+ flight combinations available.

Hi everyone!

Winter has arrived, and so I had to check the thermal insulation of my out of town residence dacha. And it just turned out a famous Chinese marketplace started to sell cheap thermal camera modules. So I decided to DIY it up and build a rather exotic and useful thing — a heat visor for the home. Why not? Especially since I had a Raspberry Pi lying around anyway… The result is down below.

Hi all!

Every person is using barcodes nowadays, mostly without noticing this. When we are buying the groceries in the store, their identifiers are getting from barcodes. Its also the same with goods in the warehouses, postal parcels and so on. But not so many people actually know, how it works.

What is 'inside' the barcode, and what is encoded on this image?



Lets figure it out, and also lets write our own bar decoder.

I came up with idea, that it would be cool to edit cell tags with help of IPython magic instead of mouse clicking and interacting with tags or metadata toolbars. So, now I can do it by typing this code directly into the cell input area:

%tags foo bar baz

Long time ago, when a mobile phone costed about 2000$ and one minute of voice call was 50 cents, pagers were really popular. Later cellular phones became cheaper, calls and SMS prices became lower, and finally pagers mostly disappeared.


For people, who owned a pager before, and want to know how it works, this article will be useful.

If you are working with Kubernetes environment then you probably make use of several existing templating tools, some of them being a part of package managers such as Helm or Ksonnet, or just templating languages (Jinja2, Go template etc.). All of them have their own drawbacks as well as advantages and we are going to go through them and write our own tool that will try to combine the best features.

This is a short article about understanding time series and main characteristics behind that.

Problem statement

We have time-series data with daily and weekly regularity. We want to find the way how to model this data in an optimal way.

Did you ever think that one day you had got into PHP web programming too quickly?
Several years have passed already, you have gained a lot of experience and can’t think of any other ways to work with web but PHP. Perhaps, you sometimes doubt the choice you have made, but are unable to confirm your doubts here and now. At the same time, you need real examples; you want to understand the changes that may occur in particular aspects of your work.

Today I will try to answer the following question: "What if we use Python instead of PHP?".

I have asked this question myself many times. I have been using PHP for 11 years already and am a certified PHP specialist. I have mastered it so it works just the way I want. I was really puzzled by several articles that criticized PHP severely (PHP: a fractal of bad design). However, when chance came, I switched to Ruby and then to Python. Eventually, I chose the latter. Now I will try to explain how we Python guys live out there.
