A HTML5 rich text editor

Squire is an HTML5 rich text editor, which provides powerful cross-browser normalisation, whilst being supremely lightweight and flexible.

...

Unlike other HTML5 rich text editors, Squire was written as a component for writing documents (emails, essays, etc.), not doing wysiwyg websites. If you are looking for support for inserting form controls or flash components or the like, you'll need to look elsewhere.

Scan a https-site for mixed content

Last week Bramus presented a cool mixed content scanner on his blog. Just for fun/as an excercise I made my own version.

The core scanner is mostly a copy of Bramus' code but there are a few noticeable differences. My version:

  • can be installed via composer
  • uses the Symfony console component
  • uses Guzzle instead of naked curl
  • can write the scanresults as json to a file
You can install the scanner with this command: ``` composer global require spatie/mixed-content-scanner ```

You'll find the instructions how to use it on github.

Create a global .gitignore original

by Freek Van der Herten – 1 minute read

Probably you're using a .gitignore file for every project. If you find yourself creating a .gitignore file for the same files on every project you should use a global .gitignore file. You can specify the location of the global .gitignore file with this command: git config --global core.excludesfile…

How To Add Swap on Ubuntu 14.04

One of the easiest way of increasing the responsiveness of your server and guarding against out of memory errors in your applications is to add some swap space. Swap is an area on a hard drive that has been designated as a place where the operating system can temporarily store data that it can no longer hold in RAM.

The information written to disk will be slower than information kept in RAM, but the operating system will prefer to keep running application data in memory and use swap for the older data. Overall, having swap space as a fall back for when your system's RAM is depleted is a good safety net.

In this guide, we'll cover how to create and enable a swap file on an Ubuntu 14.04 server.

Adding swap is only to be used to give your server a bit of breathing space. If your server is constantly using a lot of swap memory consider upgrading the amount of RAM.

A Laravel webshop original

by Freek Van der Herten – 3 minute read

Earlier today Spatie, the company where I work, launched a webshop polkadots.be. When the project started one of the first choices that we had to make was if we were going to use an existing solution or build our own custom solution. For this project we took an extensive look at some existing…

Why programmers work at night

Programmers work at night because it doesn’t impose a time limit on when you have to stop working, which gives you a more relaxed approach, your brain doesn’t keep looking for distractions and a bright screen keeps you awake.

Though I keep working at night to a minimum it sounds very familiar. It seems a bit strange but not having a deadline is great for productivity for some types of tasks.

Excel exports

Evan Miller makes the case for offering xls-exports instead of csv-exports.

Most people of your website’s users are also Excel users. When they export their data as CSV, they’ll probably just bring it into Excel first to have a look around. You should probably offer an explicit XLS export, and take it seriously.
http://www.evanmiller.org/please-offer-an-excel-export-option.html

An xls-file is capable of things that 'll never be possible in csv:

  • freezing the header row
  • formatting important cells
  • multiple sheets in one file
  • specify numer formatting
  • formulas
In the projects I've been working on I've been doing this for a couple of months. A nice Laravel package you can use is Laravel Excel.

This is how you export all values from a given repository that returns Eloquent models:


Excel::create($pathToFile, function($excel) {

    $excel->sheet('The sheet name', function($sheet) {
        $sheet->freezeFirstRow();

        $sheet->cells('A1:Z1', function($cells) {
            $cells->setFontWeight('bold');
            $cells->setBorder('node', 'none', 'solid', 'none');
        });

        $sheet->fromModel($this->yourOwnRepository->getAll());
    });

})->export('xls');

The result is an excel-file with the header row frozen and underlined and it's values in bold.
