Crowdfunding is a getting popular way of providing the initial/startup funds for a project or idea.

There are platforms for hosting a crowdfunding plaform like Kickstarter and IndieGogo which take a percentage of the collected amount (which is fair).

Alternatively, it is possible to host your own campaign to have the full control, pay no fees and overcome some limitations (like Kickstarter projects being available to only selected countries).

Crowdhoster

This is where Crowdhoster comes as it is a professional yet free and open source crowdfunding page for self-hosting campaigns.

It has an admin panel for setting up the campaign(s), defining reward levels and managing the pre-orders.

Also, there are multiple ready-to-use themes and an API to fetch the data collected.

Photoshop documents (PSD) exist for a very long time and they are mostly a “locked box”.

Alternative programs like Gimp or IrfanView exist for viewing the contents but that was hard to do via a programming language.

PSD.rb is a Ruby library, created by LayerVault, that offer a solid way for parsing Photoshop documents.

It can easily get the document structure, layer/folder info, fonts, flattened image data and more.

  • Chartkick is a Ruby gem (also has a JavaScript API which doesn’t require Ruby) for creating good-looking charts very easily and quickly.

    It integrates with 2 charting libraries: Highcharts and Google Charts where it is possible to use the same functions for generating charts with each library.

    Chartkick

    There is support for multiple chart types and multiple series in a single chart.

    And, like mentioned there is also Chartkick.js which brings the same functionality to the client-side, without Ruby.

  • Today, HTTP requests are used widely in websites as we fetch data using APIs, get screenshots or AJAX requests.

    Unirest is a pack of lightweight HTTP libraries for many languages (PHP, Ruby, Python, Java And Objective-C).

    Unirest

    It has support for GET, POST, PUT, UPDATE, DELETE operations and its methods + response structure are the same in all languages.

    The usage is very simple and straightforward. Also, it is documented well.

    Scout is a free application (with Windows and Mac versions) that allows anyone to make use of Compass and Sass without the complexity of Ruby + command line.

    The application runs Sass and Compass in a self-contained Ruby environment, has support for defining multiple projects and various settings to customize the use.

    Scout

    Using Scout, we can define custom output folders (so that any generated CSS can be directly written into our project folders) and also set the style of the CSS (nested, compressed, etc.).

    And, a logging interface displays every action performed by the app (with any errors occurred).

    FnordMetric is an open source web application for creating real-time dashboards that can visualize the data you want.

    It uses Redis as the datastore (if you have the date in another db, it should be pushed there) and allows defining our own plotting + counting functions as Ruby blocks.

    FnordMetric

    The application has a UI for for visualizing the data and, also,  it offers an HTML5/JavaScript API for inserting charts/data into web pages as widgets.

    FonrdMetric has a detailed documentation from its installation steps to API usage.

    Squash is an open source application, that is built by Square (with Ruby), for finding and killing bugs.

    The application is multi-user, has client libraries for different systems (Ruby on Rails, Objective-C, etc.) and can catch + record errors when they happen.

    Once they are caught, it sends them to the API, logs them and triggers any defined actions like sending e-mails.

    Squash

    Squash has a web interface that displays bug information and guides developers to locate + fix them. It is possible to collaborate through it, comment  to bugs or assign them to teammates.

    Also, the application also visualizes the occurrences of bugs so that their frequency can be analyzed better.

    Dashing is a flexible framework, built with Ruby (Sinatra-based) and Coffeescript, for creating attractive dashboards.

    The dashboard is formed of widgets which can pull data from any source. The widgets interface is powered by Gridster and they can be re-positioned with drag 'n drops.

    There are sample widgets like Twitter, clock or iframe to ease getting started with it and an API exists for pushing data to the widgets if wanted.

    QR Codes, a tracking code technology which was created in 1994 by Denso<Toyota to keep track of vehicles, is now a standard being used everywhere from websites to magazines, apps or stores.

    In the web, considering the mobile devices are used as the barcode reader, QR Codes are usually used as an alternative way to show app download/purchase links, wi-fi passes, mobile version URLs of websites, etc.

    I needed to create few of them in the past, used online QR Code generators and I was done in a few minutes.

    Recently, a project required hundreds of them being generated automatically and I have played with many different JavaScript + server-side solutions. I have faced solutions that are -sometimes- not working correctly, not supporting too short or long texts or they were not simple enough. Here is the list of solid and good-quality QR Code generation resources that all work very straightforward:

    P.S. I ended up using a JavaScript library which is so easy to implement, flexible in all levels, and, I knew that it would always be used by a modern browser. You can choose the solution that  fits the best to your case from the list below.

    Online QR Code Generators


    QRhacker

    QRhacker

    QRhacker is a beautifully implemented online QR code generator with many options for creating the QR code we want.

    It allows many different input types (text, URL, phone number, VCard and Wi-Fi access) and offers customizations like the roundness of the blocks, their foreground/background colors, using images for them and more. Also, the code can be painted pixel-by-pixel.

    Once the QR code is created, it can be downloaded either as an image or PDF.

    Unitag

    Unitag

    QR codes have a built-in error-correction mechanism and codes that are slightly morphed can still be recognized correctly.

    Unitag makes use of this and allows users to transform QR codes by curving the blocks, adding extra shaped and more.
