Earlier quoted context omitted.

I turned off NoScript, and uBlock doesn't show any blocked requests (the only privacy add-ons I have.) Still no video. The player loads and shows an image, the video bar shows background video loading progress and even clicking to certain parts of the video shows different image clips. Just no video. So I've just given up.

That sucks. Email me? jon@calhoun.io I'll happily work with you to figure out the issue, even if it means giving you a link to download some videos in the meantime.

I have Firefox Nightly installed now (with no extensions yet) and a blank profile which works so there's no need. I do appreciate the offer to help though.

I want to have 20+ exercises by the time the course is complete. There are about 13 planned as of now, so if you have suggestions or topics that you think would make good Go programming exercises I'd love to hear them =D EDIT: And in other news, a few people have reported the welcome email going to their spam so if it happens to you please let me know and I'll continue looking into why it is happening.

Something that is kind of unique to Go is it's crypto libraries. Using the crypto libraries in some useful way would be interesting. A cool one might be using the golang.org/x/crypto/ssh to ssh around, and send shell commands (i.e. building your own automation framework based on ssh keys)

Given Java and .NET crypto libraries, and their provider infrastructure, I fail to see what is so unique to Go's crypto libraries.

Image Processing and Analysis. Goroutines, as well as the image package, are well suited to parallel operations on bitmap data right out of the bag. From simple texture synthesis routines such as sine-wave plasma generation or mandelbrot set fractals. To advanced state-of-the-art techniques like super-resolution image enhancement and frequency domain analysis. Golang is great for image science. Especially parallel op…

> Image Processing and Analysis.

I know from reading many programming books and blog posts over the years that this is a popular topic. However, if you go down this route, please try to provide an alternative exercise which doesn't rely on visual elements to make its point. Speaking as a blind coder, image processing might be all about the numbers, but when you can't see the result of the code you've written or even conceptually understand the idea it tends to take the wind out of your sails.

I think the idea is excellent, but I have (almost) no interest in Go and I struggle to improve my javascript. Do anyone knows about a similar experience for javascript ?

Try Javascript 30 by Wes Bos. https://javascript30.com/

He's a good educator and this is a fun series of exercises to practise your JS.

Signed up for the coding excercises!Awesome site!What path would you recommend to someone who is coming from a bit of Python background. I see a lot of blurb about how Golang is the perfect fit for low latency web applications. Think “data intensive applications”. Also how good is the Golang tool chain for Raspberry pi and such like? Thanks

To answer your first question with regard to resources and getting into it first; you can start with the Go tour, and then move on to other resources. Absolutely install go and start playing around; maybe try to create a simple server or port one an easy to medium Python project. Have a look at these resources: _ 1. A Tour of Go : https://tour.golang.org/welcome/1 >> A nice step by step introductory guide through the…

I've signed up and will give this a shot. I followed the Tour of Go and was wondering where to head next.

I haven't watched the videos yet but the site looks really simple and attractive.

You lost me at "you need to create an account". Creating an account is a big step for me, I don't open accounts on a whim. I need to be committed to something to be willing to open account with them.

Your site wants me to open an account before it is willing to show me something that would commit me.

Also, to be perfectly homest, I would never open an account to see some videos. The only player in that area who can generate enough commitment from me is Netflix.

Why, if I may ask, are you even asking me to open an account? Is this about you teaching me Go or is it about you trying to monetize me? What are you logging about me? Why not make account creation optional? I don't want your site tracking my progress anyway (I'm paranoid that way).

Since it's often related, audio processing. As an example, maybe removing ad breaks from podcasts? I don't know how reasonable that would be as I haven't researched it, but could be a fun challenging project.

Probably using this FREE course as an upsell to his paid course. Still. Kudos to the creator. FREE is free. Thank you.
