hitimes | high resolution timer library for recording performance

I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8.

Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10.

I could then install mysql2 with by passing the correct libraries to it: gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include

Everything works locally, all good.

I'm trying to deploy this project with Dokku on a Debian instance. Here's the readout from the push to dokku master including the error thrown when starting the Rails server:

I postes this question because I didn't find any related answer on stackoverflow. I did everything. I will explain what I have tried. When I start the Rails server using rails s, I get the following output:

I'm trying to install Jekyll on Leopard but can't get it working. The most progress I've made is being able to run gem install jekyll in Terminal, but then I get the error make failed, exit code 2.

• I have tigerbrew installed (since brew is incompatible with leopard now)
• I have rvm installed (installed from source due to constant certificate/ssl errors)
• I have installed Ruby version 2.3.8p459 from source
• I have Xcode 3.1.3 installed

I can't install ruby from rbenv or rvm due to cert/ssl errors, that's why I've installed it from source. I can install via brew install ruby, but get the same results.

I've looked at many other posts regarding the make failed error which tends to be related to multiple Ruby versions. None of the answers on these pages worked as I've installed everything from source (ruby has never been installed by brew, rbenv or rvm). I have tried installing ruby with all of the above but got the same error. Each time I've tested installing Ruby either from source or from tigerbrew/homebrew I've clean installed a new system of Leopard + Xcode etc. I've also tried this on multiple machines.

I've just updated rubygems to version 3.0.2, which fixed some certificate errors when installing gems but hasn't fixed the problem.

Is there anything else I can do to get this working??

Below is the output from Terminal when I run gem install jekyll.

Ubuntu 16.04. LTS (using Vagrant) Ruby 2.2.0 (using rbenv)

I have error during starting passenger. I googled it but nothing relevant on Github or SO so far.

I'm trying to run a simple Ruby code using PubNub Ruby SDK 4.0.25, but when running ruby subscriber.rb I'm receiving in logs error shown below:

I'm having trouble reading from a TFRecord file with "many" (more than ~500) events. If I create a file with 500 events, everything is fine, but more than 500 causes an error when I try to read and parse the file:
