    1. This works as expected (using r for making it an exact Rational): p Time.utc(2007, 11, 1, 15, 25, 0, 123456.789r) # => 2007-11-01 15:25:00.123456789 UTC
    1. JSON parsing is always pain in ass. If the input is not as expected it throws an error and crashes what you are doing. You can use the following tiny function to safely parse your input. It always turns an object even if the input is not valid or is already an object which is better for most cases.

      It would be nicer if the parse method provided an option to do it safely and always fall back to returning an object instead of raising exception if it couldn't parse the input.

    1. Creating and calling a default proc is a waste of time, and Cramming everything into one line using tortured constructs doesn't make the code more efficient--it just makes the code harder to understand.

      The nature of this "answer" is a comment in response to another answer. But because of the limitations SO puts on comments (very short length, no multi-line code snippets), comment feature could not actually be used, so this user resorted to "abusing" answer feature to post their comment instead.

    1. However, a ActiveRecord::Rollback within the nested transaction will be caught by the block of the nested transaction, but will be ignored by the outer transaction, and not cause a roll back! To avoid this unexpected behaviour, you have to explicitly tell rails for each transaction to indeed use proper nesting: CopyActiveRecord::Base.transaction(joinable: false, requires_new: true) do # inner code end This is a safer default for working with custom transactions.

    1. Note that this will pull the container if it exists. Pulling even the small alpine is quite an overhead just to get that information. Not mentioning the several GB-Image one often has in CI-Environments.
    1. '

      because it's in YAML

      but this means you can't use any ' in the actual script line

      or you have to use different delimiters if you do

      bottom line is it makes it harder to write/include your script than simply creating a separate shell script file.

    1. I just noticed that git svn clone has an optional --log-window-size parameter, though, and it lets you determine how many log entries are scanned at a time. The default is 100, but if you bump it up to 5000, then it only takes a few minutes to clone the plugin, making git-svn a viable option.

    1. The issue I see is that the browser agent might be smart enough to learn the autocomplete attribute and apply it next time it sees the form. If it does do this, the only way I can see to still get around the problem would be to dynamically change the autocomplete attribute value when the page is generated.
    1. If you are signed in to Chrome with the a Google account and try to sign it to that Google account on a web page, Chrome will not offer to save that password.

      You have to "disconnect" your Google Account from Chrome, which to me is an unfortunate workarounds.

      They should just give the option to people who want to both have the accounts connected and save that password.

    1. The easiest solution I found for this was simply to make small tweaks to avoid it altogether, e.g. “From: New York” instead of “From New York”. en.yml1 from_x: "From: %{x}" sv.yml1 from_x: "Från: %{x}" fi.yml1 from_x: "Lähettäjä: %{x}" Apparently this is enough to avoid inflecting the place name. Consult a speaker of the target language and see if you can come up with a workaround similar to this.
    1. To accomplish this, Logic Hop adds the CSS class .logichop-render-hide with the parameter opacity: 0 !important; to the <body> element. After the container is ready and Logic Hop has processed your personalizations the CSS class is automatically removed and the page is displayed. The Anti-Flicker Timeout setting is the time in milliseconds until page is automatically displayed (in the unlikely event Logic Hop takes too long to load).
    2. While caching is great for speed and performance, it bypasses Pre-page Level and Page Level processing and the default Logic Hop functionality. Logic Hop has a Javascript Mode feature which allows the use of any cache Plugin while keeping the benefit of the page view tracking, goal tracking and page redirects.
    1. Output to STDERR for processes run through the Rack interface is directed to the master Apache error log file rather than the domain/subdomain specific log file. You do not have direct access to the master log file. This limitation can make debugging initialization errors (in particular syntax errors and gem resolution issues) tricky. Passenger will often produce an error output webpage including a stack traceback. However, in some cases it does not. If you have a persistent problem and Passenger is not producing sufficiently useful error output, you can try contacting the DreamHost support staff and ask them to examine the master log file for you

    1. before_destroy callbacks should be placed before dependent: :destroy associations (or use the prepend: true option), to ensure they execute before the records are deleted by dependent: :destroy.
    1. ssh doesn't let you specify a command precisely, as you have done, as a series of arguments to be passed to execvp on the remote host. Instead it concatenates all the arguments into a string and runs them through a remote shell. This stands out as a major design flaw in ssh in my opinion... it's a well-behaved unix tool in most ways, but when it comes time to specify a command it chose to use a single monolithic string instead of an argv, like it was designed for MSDOS or something!

    1. Note: Users must log out and back in to gain rvm group membership because group memberships are only evaluated by the operating system at initial login time.
    1. The IdentitiesOnly yes is required to prevent the SSH default behavior of sending the identity file matching the default filename for each protocol. If you have a file named ~/.ssh/id_rsa that will get tried BEFORE your ~/.ssh/id_rsa.github without this option.

    1. Using with is not recommended, and is forbidden in ECMAScript 5 strict mode. The recommended alternative is to assign the object whose properties you want to access to a temporary variable.
