Start sidekiq automatically on OSX

由 坚强是说给别人听的谎言 提交于 2021-02-08 11:52:12
问题 I have coded up a small ruby gem that I use on my laptop to check disk space and other things. I am using a sidekiq worker that runs periodically and emails me status updates. I was wondering how to make a sidekiq worker run automatically after I restart OSX? Is this possible? Cheers 回答1: To run sidekiq you need to run: bundle exec sidekiq . If you want to run this on startup then you can follow these steps: Start Automator.app; Select "Application"; Click "Show library" in the toolbar (if

Finding the intersection of two lines

由 孤人 提交于 2021-02-08 11:20:34
问题 I have two lines: y = -1/3x + 4 y = 3x + 85 The intersection is at [24.3, 12.1] . I have a set of coordinates prepared: points = [[1, 3], [4, 8], [25, 10], ... ] #y = -1/3x + b m_regr = -1/3 b_regr = 4 m_perp = 3 #(1 / m_regr * -1) distances = [] points.each do |pair| x1 = pair.first y2 = pair.last x2 = ((b_perp - b_regr / (m_regr - m_perp)) y2 = ((m_regr * b_perp) / (m_perp * b_regr))/(m_regr - m_perp) distance = Math.hypot((y2 - y1), (x2 - x1)) distances << distance end Is there a gem or

in iOS 11 the keyboard autocorrect creates invalid UTF8

由 我是研究僧i 提交于 2021-02-08 11:15:42
问题 Our app accepts user text input which we then save to a server-side database. In iOS 11 when you enter two "-" characters in a row they are automatically combined into an emdash (—). When you enter three "-" characters in a row you end up with an emdash + a half emdash which has an invalid terminator. This is causing issues for my rails server which cannot parse this string because it is invalid. The string looks like this: \xE2\x80\x94\x00 回答1: 'Smart dashes' as it is called, is the process

Change the default file download path for Edge using selenium

由 可紊 提交于 2021-02-08 10:46:28
问题 I was using selenium-ruby for automating browser application. I want to simulate file download scenario. When I want to execute for chrome I had a method named "download_path", its value can be changed at run-time and when download file it will be saved at my destination path. But, when I execute the same code for edge there is no method support for "download_path" in edge. Is there any way to set my default download location at runtime? Chrome Code: @browser = Selenium::WebDriver.for :chrome
