Universal G-Code Sender
A cross-platform G-Code sender for GRBL, Smoothieware, etc.
A full-featured gcode platform used for interfacing with advanced CNC controllers like GRBL , TinyG, g2core and Smoothieware. Universal Gcode Sender is a self-contained Java application that includes all external dependencies and can be used on most computers running Windows, MacOSX or Linux. With older versions of GRBL UGS is pretty reliable when it comes to jogging, but there are limitations. With GRBL 1.1 this is no longer the case when using the new JOG MODE syntax. This first-class jog mode guarantees the GCODE state will be unaltered and also allows you to stop a jog while it is in progress. UGS uses this new syntax automatically when it detects a version of GRBL which supports it. -

PHPMailer
The classic email sending library for PHP
PHPMailer – A full-featured email creation and transfer class for PHP. Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings. SMTP authentication with LOGIN, PLAIN, CRAM-MD5, and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports. Validates email addresses automatically. Many PHP developers need to send email from their code. The only PHP function that supports this directly is mail(). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments. Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the mail() function directly is just plain wrong, if not unsafe! -

Acrylic DNS Proxy
A local DNS proxy which improves the performance of your computer
Acrylic is a local DNS proxy for Windows which improves the performance of your computer by caching the responses coming from your DNS servers and helps you fight unwanted ads through the use of a custom HOSTS file (optimized for handling hundreds of thousands of domain names) with support for wildcards and regular expressions. When you browse a web page a portion of the loading time is dedicated to name resolution while the rest is dedicated to the transfer of the web page contents. What Acrylic does is to reduce the time dedicated to name resolution for frequently visited addresses closest to zero possible. Furthermore Acrylic's sliding expiration caching mechanism and DNS silent updates are able to improve the browsing experience independently of the browser. With Acrylic you can also gracefully overcome downtimes of your DNS servers without disrupting your work, because in that case you will at least be able to connect to your favourite websites and to your email server. -
