| # INSTRUCTIONS: | |
| # 1. Follow the installation instructions at | |
| # https://nixos.org/nixos/manual/index.html until | |
| # /mnt/etc/nixos/configuration.nix is edited | |
| # 2. Replace that file with this one: | |
| # -> curl -L -o /mnt/etc/nixos/configuration.nix https://go.nzbr.de/zoomvm | |
| # 3. You will need to edit this configuration if you want a locale other than | |
| # german (i18n and xserver.locale) or not use UEFI (boot.loader) | |
| # 4. Run `nix-env -i git` to install git on the live system (may take some time) | |
| # 5. Run nixos-install |

#Anonymous records. A solution to the problems of record-system.
Please, beware that the proposal that follows has been implemented as a library.
The current record system is notorious for three major flaws:
It does not solve the namespacing problem. I.e., you cannot have two records sharing field names in a single module. E.g., the following won't compile:
data A = A { field :: String }
| // Usage: $form.find('input[type="checkbox"]').shiftSelectable(); | |
| // replace input[type="checkbox"] with the selector to match your list of checkboxes | |
| $.fn.shiftSelectable = function() { | |
| var lastChecked, | |
| $boxes = this; | |
| $boxes.click(function(evt) { | |
| if(!lastChecked) { | |
| lastChecked = this; |
