Add Collaboration Features to your Website with a Line of Code

Tools like Google Docs include real-time collaboration features that let multiple people work on the same document or spreadsheet at the same time. Then you have screen sharing tools, join.me or Chrome Remote Desktop for example, where there’s a master presenter and remote viewers can follow along.


Website with Real-time Chat

TogetherJS is a Mozilla project that brings similar collaboration features to your own website but without any coding. Once enabled, visitors to your website will be able to interact with each other on your site in real time.


They’ll able to see each other’s cursor (like in Google Docs), the clicks are highlighted and the screen content stays synchronized. Visitors will also have the ability to text chat and audio chat (using WebRTC) with each other while staying on your website. All this and more with a line of code.


Add TogetherJS to your own Website


To get started, all you have to do is insert a little JavaScript snippet anywhere on your web page(s). There are several configuration parameters available for the widget but we will use the default settings to keep things simple.



<script>
TogetherJSConfig_autoStart = true;
</script>
<script src="http://ift.tt/1vtXj93;

This will add a little floating widget to your website that will be visible to all visitors. They can click the “+” button in the widget to generate a unique TogetherJS URL. Anyone who clicks this URL will be able to interact with each other on your page in real time. It can’t get any simpler.


I have put up a quick page where you can test TogetherJS capabilities. Click the “+” icon and send the unique URL to another person to chat in real-time.


Add TogetherJS to any Website


There’s more. You can add TogetherJS features to any web page on the Internet with the help of a bookmarklet.


TogetherJS


This bookmarklet will load the TogetherJS library on the current web page and you can give the chat session a unique name. Another person can launch the bookmarklet on the same page on their own computer, enter the same session name and you’ll be instantly connected.


You can co-browse, watch each other’s activity or chat atop the page.

Professional Video Editor `Lightworks` v12 Available For Download

Lightworks, a professional video editing and mastering software, has reached version 12, this being the first release which gives the same experience on Linux, Windows and Mac OSX:



"The release of Lightworks version 12 marks a unique milestone in that for the first time, the same version runs on the Windows, Linux and Macintosh platforms - a unique achievement for a professional, fully featured NLE.


As a result of Lightworks' intelligent software architecture, new features and fixes for all three versions will be available virtually at the same time, barring operating system-specific issues"







The latest Lightworks 12 includes a new Content Manager structure, rewritten Lightworks Play engine for improved playback performance along with new Blur, Color Correction and Selective Color Correction effects and more.







Lightworks continues to be available as free to use however, the pro license prices increased with this release and a one month license now costs £14.99 | €19.99 | $24.99, a one year license is £99.99 | €134.99 | $174.99 and an Outright (doesn't expire, includes two activations) license is £249.99 | €337.99 | $437.99.



The difference between the free and paid (pro) version is that the free version allows exporting only to MPEG4/H.264 at up to 720p while the pro version has a much wider range of output options, includes advanced project sharing, 3D stereoscopic output, user-definable project locations, rendering and Hardware I/O support.



Changes in Lightworks 12:


  • Same experience on all three platforms;

  • Added new Content Manager structure:

    • Bins and Groups (previously racks) are now all visible within the content manager;

    • Multicam Bins (previously Sync groups) are now all visible within the content manager;

    • The Search function has been incorporated into the content manager (click the magnifying glass);

    • Added Clips, Subclips, Prints, Syncs, Edits, Searches, Everything and Recent filters to the content manager;

    • Added ability to create and edit Filters;

    • Added ability to create Filters based on search criteria and manage them;

    • Added the ability to drag/drop files from the OS directly into an open bin (cannot import to Filters);

    • Added the ability to import directly into an existing bin (cannot import to Filters);

    • And much more!



  • Optimised the drawing pipeline to create a much more responsive user interface;

  • Rewritten the Lightworks Play engine for improved playback performance;

  • Added improvements to the export panel to make it easier to select a format for export;

  • Added entirely new Blur effect to the Effects panel;

  • Added powerful new Colour Correction effect;

  • Added powerful new Selective Colour Correction effect;

  • Added import of Final Cut Pro 7 XMLs;

  • Added 4K support for ProRes formats (Blackmagic cameras).




Note: there are some known issues and limitations across all platforms. On Linux, Lightworks only supports Nvidia and ATI graphics (Lightworks strongly recommends using proprietary drivers or else the app might not work properly), there is no Firewire support, no Quicktime/MPEG4 export option, no .wmv support, audio may not be present on some uncompressed avi files and there are only 64bit deb and rpm files available for download, among others.

Restrict Google Forms to only Allow One Entry Per Person

You have created a survey using Google Forms but people have quickly figured out a way to game your poll and tilt the results in their favor. They are submitting multiple entries, and because Google Forms will not record the I.P. address or the email of the form submitter, it is nearly impossible for you to separate the duplicate submissions from the genuine entries.


How do you restrict Google Forms to only allow a single entry from a user?


If you are a Google Apps user, you can always restrict the Google Form to accept entries only from users who are part of your domain and the response spreadsheet will then record the username of the form submitter. However if you have a regular Gmail / Google Account, you have another option now to prevent multiple form submissions from the same user.


While creating the Google Form, click the Settings bar and turn on the option that says “Allow only one response per user.” When the unique option is enabled for a Google Form, respondents will have to sign-in with their Google account to access the form. Their email address won’t be recorded in the response sheet but Google Form will not allow another entry from the same Google Account.


If someone tries to fill the Google Form again, a warning message will be displayed saying “You’ve already responded. You can only fill out this form once. Try contacting the owner of the form if you think this is a mistake.”


This is by far the easiest approach though it does put your Google Form out of reach of people who do not have Google Account or those who are skeptical of associating the email address with their form entry (though this association is completely hidden from the form owner).

Ubuntu 14.10 Utopic Unicorn Final Beta Available For Download




Ubuntu 14.10 Utopic Unicorn final beta was released today, this being the first and only milestone for Ubuntu Utopic (while for the Ubuntu flavors, this is Beta 2). Let's take a look at what's new.




And I mean "look" figuratively, because there are almost no visual changes in this Ubuntu final beta release. For instance, this will probably be the first Ubuntu release in which Unity (now referred to as Unity 7, not to be confused with the latest Unity 8 which is used on the phone) won't get any new features - of course, unless that happens in the month that's left until the final release, but that's unlikely.



However, Unity 7 did receive quite a few bug fixes and minor improvements and the most notable were related to HiDPI support: the Dash previews, lockscreen and other Unity bits were updated with proper UI scaling based on current monitor scaling. You can check out the complete Unity 7 changelog HERE.





systemd available but not used by default, improved hybrid graphics support, Linux Kernel features




With Ubuntu 14.10 Utopic Unicorn, the controversial systemd (208) is available in the repositories, and Ubuntu can finally boot with systemd, but it's not yet default because there are many packages which only have upstart jobs and they need to be updated to provide corresponding systemd units. Ubuntu will switch to systemd by default "when it's ready", says Martin Pitt



Hybrid graphics support was improved with Ubuntu 14.10 Utopic Unicorn and the changes in this area include:


  • nvidia-prime and gpu-manager now support GDM (these changes were backported to older Ubuntu versions, but without the GDM patch that allows this);

  • added support for "gpumanager_uxa" and "gpumanager_modesetting" boot parameters, so that there is an option to force NVIDIA Optimus systems (that don't work well with Intel/SNA) to use either Intel/UXA or modesetting);

  • allow RandR offloading even without bbswitch;

  • more.




It's also important to note that Ubuntu 14.10 Utopic Unicorn final beta ships with the Ubuntu Kernel 3.16.0-17, based on the upstream 3.16.3 Linux Kernel. Since the Linux kernel 3.13 (which is used in the previous Ubuntu version - 14.04), there were some important improvements, such as:


  • zram is considered stable with Linux 3.14; zram received LZ4 compression support;

  • stable support for Intel Broadwell CPU graphics (3.14);

  • the SCHED_DEADLINE scheduling class was added to the Linux scheduler in version 3.14 of the Linux kernel mainline;

  • faster resume from suspend;

  • EFI mixed mode support: 64-bit kernels can be booted from 32-bit firmware (with Linux 3.15);

  • various Nouveau improvements, including initial NVIDIA Maxwell GPU support, initial GK20A and GK110B GPU support as well as support for allowing to change the frequency of the GPU from the BIOS predefined values for nv40, nvaa, and nve0 clock types;

  • Radeon performance improvements through improved APU power management have been enabled in some APUs;

  • Intel Cherryview graphics support;

  • NVIDIA Tegra PRIME support;

  • Broadwell support for the Intel P-State driver (3.16);

  • various other improvements to audio and sound, btrfs and ext4 improvements, better support for newer laptops and much more.




You can read more about all the important Linux kernel changes here: Linux 3.14 | Linux 3.15 | Linux 3.16





Applications / packages




Among the applications shipped by default with Ubuntu 14.10 Utopic Unicorn final beta are Firefox 32, Thunderbird 31.1, LibreOffice 4.3.1rc2, Nautilus 3.10.1, Rhythmbox 3.0.3, Empathy 3.8.6, Transmission 2.82, Shotwell 0.20.0, Gedit 3.10.4, Brasero 3.10.0 and Totem 3.10.1 (and others), on top of Unity 7.3.1+14.10.20140915 and GTK 3.12.2. Also, Utopic includes Mesa 10.2.6 (but 10.3 is available in the proposed repository) and Xorg server 1.16.0.



Ubuntu 14.10 Utopic Unicorn final beta ships with GTK 3.12.2 and not the latest 3.14 (and, as you can see from the app list above, mostly GNOME 3.10 apps) because GNOME 3.14 was just released and Ubuntu 14.10 had its feature freeze on August 21st.



As for the default GNOME applications included by default in Ubuntu (w/ Unity), they are still at version 3.10 because they need to be patched to properly support Unity (to use regular window borders and menus) and it looks like the Ubuntu developers didn't have time to update them for this Ubuntu release.



There is some good news for GNOME fans though: GNOME Shell was updated to version 3.12.2 is available in the official Ubuntu 14.10 Utopic Unicorn repositories.





Download Ubuntu 14.10 Utopic Unicorn final beta




Before downloading it, remember that Ubuntu 14.10 Utopic Unicorn is in beta, so you may encounter issues! That said, I've been using Ubuntu 14.10 for a while and, like the previous development cycle, it feels pretty stable and robust and I didn't encounter any major issues.






Ubuntu 14.10 (stable) will be released on October 23rd.

gdrive: A Simple Google Drive CLI Client (Cross-Platform)

gdrive is a simple command line Google Drive client written in Go, available for Linux, Windows, FreeBSD and Mac OS X.






The tool was created for uploading and downloading files from/to Google Drive and it doesn't support any kind of synchronization. In fact, grive can't even download multiple files at once.



However, gdrive is still useful for one-off uploads / downloads, especially since Grive, another command line Google Drive client (which does support sync) that's quite popular among Linux users, wasn't updated since May, 2013 and looks pretty much dead.



gdrive features:


  • upload/download single files (and optionally, it can convert uploaded files to Google Docs format);

  • upload folders;

  • create folder;

  • share file or folder from your Google Drive;

  • generate preview and download url;

  • show shared status;

  • search your Google Drive;

  • cross-platform.






Using gdrive




To use gdrive, you must firstly authenticate it with Google. Do this, simply run "drive" in a terminal (this assumes that you've installed the gdrive binary as "drive", by following our instructions below):


drive

A link should be displayed in the terminal, which you need to copy and paste in your web browser. In your web browser, click "Accept" and copy the resulting code and paste it in the terminal where you ran "drive".



To be able to download files from Google Drive to your computer, you must use the file id. To find out this id, run the following command to get a list of recent files (and their ids) available in your Google Drive:


gdrive list

Example:


$ drive list
Id Title Size Created
0B0tRrdcY7CwJZHh5ZmVpZHRMYW8 drive-linux-amd64 10 MB 2014-09-25 17:47:08
0B0tRrdcY7CwJY2lNS2x3NC1lQUU drive-linux-386 8 MB 2014-09-25 17:47:01
0B0tRrdcY7CwJR3lmZnlRaFZwOHc drive-linux-arm 9 MB 2014-09-25 17:46:57
0B0tRrdcY7CwJQlRfQUVxY2hkWUE drive-linux-rpi 9 MB 2014-09-25 17:46:52


Note that "drive list" lists all your recent Google Drive files, even those shared with you, etc.



Now you can download a file from Google Drive, by using the following command:


drive download --id FILE_ID

where "FILE_ID" is the file id which you can see when using the "drive list" command.

File download example:


$ drive download --id 0B0tRrdcY7CwJZHh5ZmVpZHRMYW8
Downloaded 'drive-linux-amd64' at 10 MB/s, total 10 MB




To upload a single file or a folder to Google Drive, use the following command:


drive upload --file /PATH/TO/FILE_OR_FOLDER_NAME

File/folder upload example:


$ drive upload --file drive-linux-amd64

Id: 0B0tRrdcY7CwJZHh5ZmVpZHRMYW8
Title: drive-linux-amd64
Size: 10 MB
Created: 2014-09-25 17:47:08
Modified: 2014-09-25 17:47:06
Owner: Alin Andrei
Md5sum: 82333d9c678af60a727779349a310a4e
Shared: False
Parents: 0B0tRrdcY7CwJWjFOTzd0YkpOTms
MIME Type:
Uploaded 'drive-linux-amd64' at 1 MB/s, total 10 MB


Important: gdrive can't upload multiple files unless you place them in a folder and pass the folder path to gdrive - for instance, you can use wildcards to upload multiple files in the current directory at once (so for example, "drive upload --file *.txt" won't work).



To see all the supported commands, use the following command:


drive --help



For more information and examples, see the gdrive GitHub page.





Install gdrive in Linux




The gdrive GitHub page offers binaries for Linux (well as Windows, etc.) for 32bit, 64bit, Arm and a binary especially for Raspberry Pi. To install it, download the binary, place it in your home folder and run the following command to install it to /usr/local/bin/ as "drive":




cd && sudo install drive-linux* /usr/local/bin/drive



That's it.





Download gdrive




Download gdrive (binaries available for Linux - 32bit, 64bit, Arm and Raspberry Pi -, Windows, Mac and FreeBSD as well as the source code)



To report bugs, help with its development, etc. see the gdrive GitHub page.

Debian Switches Back To GNOME From Xfce As Default Desktop





Debian switched to Xfce as the default desktop environment back in November 2013. But that didn't last long because a few days ago, Debian restored GNOME as the default desktop, based on preliminary results from the Debian Desktop Requalification for Jessie.



According to Joey Hess, the Debian developer who performed this change, the main reasons for Debian switching back to GNOME as the default desktop are related to accessibility and systemd integration:




"Some desired data is not yet available, but at this point I'm around 80% sure that gnome is coming out ahead in the process. This is particularly based on accessibility and to some extent systemd integration".



- Joey Hess, Debian developer




As far as accessibility is concerned, Joey mentions that GNOME and MATE are ahead by a large margin while other desktops still need significant upstream work. As for Systemd, GNOME is ahead of all desktops which are "stuck paying catch-up to ongoing changes in this area".



Of course, those aren't the only reasons that influenced this decision. Recent GNOME 3 improvements are fairly important too and so is the fact that unfortunately, the Debian Xfce team is pretty small.



Basically, the only reason not to switch to GNOME was the media size, but it looks like that wasn't enough to block this change.



If you're wondering why MATE wasn't selected as the default desktop environment for Debian, well, that's because MATE is new in Debian so it doesn't have many users yet.



The release date for the next Debian stable version, codenamed "Jessie" (8.0), is yet to be announced. The freeze is expected on the 5th of November 2014.



Do you use Debian? What do you think?
