Hi folks. Just a quick headsup, that older posts and images, may have been lost unfortunately, because I made the terrible mistake, when I migrated over from my old blog, that I forgot to download all the images from the remote host. For lack of options, I deleted the images. :/ Sorry for the inconvencience! Gergely.
Intro Hi folks. Today, I would like to write about how to do HTTPS for a website, without the need to buy a certificate and set it up via your DNS provider. Let’s begin. Abstract What you will achieve by the end of this post: Every call to HTTP will be redirected to HTTPS via haproxy. HTTPS will be served with Haproxy and LetsEncrypt as the Certificate provider. Automatically update the certificate before its expiration....
Intro Hi Folks. This is a follow up on my previous post about Google Sign-In. In this post we will discover what to do with the information retrieved in the first encounter, which you can find here: Google Sign-In Part 1. Forewords The Project Everything I did in the first post, and that I’m going to do in this example, can be found in this project: Google-OAuth-Go-Sample. Just to recap, we left off previously on the point where we successfully obtained information about the user, with a secure token and a session initiated with them....
Intro Hey folks. So, there is this project called Huginn which I absolutely love. But the thing is, that for a couple of scrappers ( at least for me ), I don’t want to spin up a whole rails app. Hence, I’ve come up with RScrap. Which is a bunch of Ruby scripts run as cron jobs on a raspberry pi. And because I dislike emails as well, and most of the time, I don’t read them, I opted for a nicer solution....
Intro Hello folks. Today, I would like to tell you about my configuration for a low budget Home Theater setup. My tools are as follows: FLIRC Raspberry Pi 2 500G SSD An a good ‘ol wifi TL;DR Use Flirc for remote control, omxplayer for streaming the movie from an SSD on a headless PI controller via SSH and enjoy a nice, cold Lemon - Menta beer. Flirc First, the remote control....
Update: This post ignored the fact that this works for utf-8 characters only. Characters which are stored on more than 1 byte will cause trouble. Look at this Effective Go Example. for pos, char := range "日本\x80語" { // \x80 is an illegal UTF-8 encoding fmt.Printf("character %#U starts at byte position %d\n", char, pos) } Prints: character U+65E5 '日' starts at byte position 0 character U+672C '本' starts at byte position 3 character U+FFFD '�' starts at byte position 6 character U+8A9E '語' starts at byte position 7 Keep this in mind when working with strings....
Quick reminder. If you have a never changing regex in Go, do NOT put it into a frequently called function. ALWAYS put it into a global variable. I’ll show you why. Benchmark for code with a variable in a frequently called function: BenchmarkNumber-8 30000 41633 ns/op BenchmarkAreaCode-8 50000 27736 ns/op BenchmarkFormat-8 50000 29263 ns/op PASS ok _/phone-number 5.110s Benchmark for code with the same variable outside in a global scope:...
Hi folks. Quick gotcha, when working with Drupal. If you just freshly installed it, and everything seems to work fine, and yet you are experiencing things like, the admin toolbar is randomly disappearing, or configuration is not saved; than you might not have modrewrite enabled on your apache server. Because, by default, Drupal has clean url enabled, that needs URL rewriting on apache. So, step one. Have this in your ....
Hi folks. I wanted to take the time to share with you a talk that I recently did. The slides and the source I used, can be found here: Github. And then, there is also a docker image which contains all the plugins, job configurations and all the practices which I did during the talk. Please feel free to have a go with it. DockerHub - Jenkins Best Practices. For easy access and reading, here are the slides on Slideshare: Jenkins Best Practices Slides....
Though it could be done better, I’m sure, but I’m actually pretty satisfied with this one. It loops only twice as opposed to filtered ranges and whatnot other solutions to the sieve. I was thinking of rather creating a list and deleting elements from it, but that’s already three loops. Maybe I’ll do a benchmark later on more solutions. # Sieve contains a function to return a set of primes class Sieve def initialize(n) @n = n end # Returns a list of primes up to a certain limit # @param n limit # @return list of primes def primes marked = [] primes = [] (2....
