Amazon Web Services CloudSearch is a search engine and it’s offered in a SaaS model (as well as Elasticsearch what I’ve already explained here). I’m currently writing an article about it so I’ll skip the way how to set it up and how it works. Unfortunately, CloudSearch isn’t free. It doesn’t cost much if you take a look at everything what you get. For more information on pricing check here. There’s few issues with CloudSearch. One of them is ...

Jeżeli korzystasz z Visual Studio Code to też duże prawdopodobieństwo, że korzystasz także z Gita jako system kontroli wersji. Według tych porad możesz ustawić Visual Studio Code jako domyślny edytor dla Gita oraz jako domyślny difftool czyli narzędzie pokazujące zmiany pomiędzy dwoma commitami.

Application Insights is a performance monitoring service, created by Microsoft and available on Azure. It gives you space to store the performance metrics and logs of your application (200MB for free!), as well as functionalities to search and manage them. In this post I am not going to present you the whole platform – Microsoft already did it in the Azure documentation, but rather focus on an element of the log collection, named dependency calls tracking. I did some ...

Reading time ~4 minutes This post is an analysis of a very interesting optimization proposed by Nicholas Frechette in the comments under the previous post. He proposed to use one of the oldest tricks in performance cookbook - divide and conquer. Well, it did not turn out as I expected.Saga Before I go further here are some link to the previous posts on the problem of calculating similarities and then optimizing. This thread grew to a few post. Here are all of them:How I calculate similariti...

Welcome to 2017 my dear folks! New year, new me – right? Not entirely correct, as I’d rather paraphrase this sentence to sound more like “new year, new projects (and tons of new code)”. Wondering what I’d like to achieve within the next 365 days (or make it 363 to be precise)?

Studia czy się opłacaStudia Studia są ważne, bez nich nie zostałbym programistą. Przed 1 semestrem inżyniera, robiłem różne rzeczy. Stronki na joomli, podstawowe skrypty php, stawianie serwera Lineage 2 (oh ile ja życia na to straciłem, lecz języka się nauczyłem, english of course :) ). Już pierwszy semestr, pierwsze zajęcia programowania I, pierwszy raz z delphi, udowodniły, że nie potrafię programować. Kompilator / kompilacja / linkowanie - słowa obce. To był moment mojej pierwszej poważnej decyzji...

How to report your SQL - FSharp and XPlot make it easy 26 Dec 2016 | Category: Programming | Tag: F#, SQL It's a time to go further. Recently we modified SqlProfilerTraceAnalyzer by adding different ways of showing recorded trace. Today we'll do something even better - we'll generate an HTML page with charts showing count, the total and the average time for our SQL. After that, we'll add a table containing information about our store procedures. Last time we used F# Charting, but today we'll take a...

Visual Studio is an awesome tool. It has great editor, great debugger and tooling. Almost –  a prefect one*. But it lacks in one aspect. And it lacks greatly. It’s Output window is monochrome. The good thing is that there’s a solution for that. The Output window provides a lot of useful info. There you can find logs form build, tests results and debug information that are printed from the application. But if it looks like this – it’s hardly readable. It’s missing colors. Colors are everything. It gr...
