We recently discovered this great free alternative to Skype which doesn’t need to be installed on your system. You can access it directly on the web at https://whereby.com. You can have video conversations with up to 4 people at once and guests to your “room” don’t have to register to join in.
It takes less than a minute to create your room and share the link with someone you want to join you for a video chat.
I suggest you “claim” your room by registering; this allows you to “lock” your room to stop non-invitees from joining; it also reserves the room for you so that no-one else can claim it. There’s lots of information on their site but essentially it’s a very quick and easy process.
Zoom is a great replacement, not only for Skype, for also for TeamViewer as it can also allow secure remote access for help with your computer!
You need to create and maintain an account via zoom’s web portal. Then you download the app (https://zoom.us/download) and install it into your system – very easy! The advantage of running the program from your system instead of the via web is that it is much faster than the http(s) protocol, so video and audio work better with less break up.
To get Debian to communicate with your Android phone so that you can download/backup your photos, videos, documents, etc onto your computer, you need to install a couple of packages. Open a Terminal and type:
sudo apt-get install jmtpfs gvfs-backends
Make sure when you connect your phone to your PC that (on your phone) you choose Media device (MTP), not Carera (PTP).
You should now be able to access media on the device by just clicking it on Thunar (file manager).
Don’t forget to Unmount/Eject the drive in Thunar BEFORE removing the USB cable, in the same way you would do with a USB stick.
In brief, for width (preserving the aspect ratio) (change the 200 for your desired width in pixels):
convert example.png -resize 200 example.png
for height (still preserving the aspect ratio):
convert example.png -resize x100 example.png
It is also possible (and easy) to process several images at the same time. For example, the following command would take all PNG files in the current directory, give the all a width of 600px and save a new copy of each with “-600px” added to the beginning of each file name. The directory will now contain the old and the new image files.
for file in *.png; do convert $file -resize 600 600px-$file; done
First you need to install pacpl. Open a Terminal and type:
sudo apt-get install pacpl
Any dependencies, as usual with Debian, will also be installed.
Ensure that your CD is in the drive, and decide in which directory you want to put the resulting MP3 tracks – I would suggest your Music directory which will probably be /home/[yourname]/Music. It’s a good idea to create a directory here with the name of the artist, so the files will be put directly into /home/[yourname]/Music/[ArtistsName] as they are copied & ripped.
pacpl --rip all --to mp3 --outdir /home/[yourname]/Music/[ArtistsName]
If you want to check the manual, just type:
man pacpl (q to close it)
or pacpl --longhelp (q to close it)
You can print a LibreOffice Writer document as a brochure or a booklet. That is, Writer prints two pages on each side of the paper, so that when you fold the paper, you can read the document as a book.
When you create a document that you want to print as a brochure, write your document in ordinery A4 pages, using portrait orientation for the pages. Writer will apply the brochure layout when you print the document.
To Print a Brochure
Choose File – Print.
In the Print dialog, click Properties.
In the properties dialog for your printer, set the paper orientation to landscape.
If your printer prints duplex, and because brochures always print in landscape mode, you should use the “duplex – short edge” setting in your printer setup dialog.
Return to Print dialog, and click the Page Layout tab page.
For a printer that automatically prints on both sides of a page, specify to include “All pages”.
If you print a document in portrait on a landscape page, two opposing sides in a brochure will be printed next to each other. If you have a printer with double-sided printing capability, you can create an entire brochure from your document without having to collate the pages later. If you have a printer that only has single-sided printing capability, you can achieve this effect by first printing the front pages with the “Front sides / right pages /odd pages” option marked, then re-inserting the entire paper stack in your printer and printing all the back pages with the “Back pages / left pages / even pages” option marked.
Note: If LibreOffice prints the pages in the wrong order, open the Options tab page, select Print in reverse page order, and then print the document again.
Chrome, by default, allows cookies to be set by all websites. We advise installing the “Vanilla Cookie Manager” extension so that you can control which websites can save their cookies on your system. You only really need to allow cookies from sites that you want to interact with, such as sites that you need to log in to for shopping, banking, webmail, facebook, etc.
Installing Vanilla Cookie Manager
Tools > Extensions
Click “Get more extensions”
In the search box, type Vanilla Cookie Manager
In the resulting page, click the “Add to Chrome” button and click Add in the confirmation box.
Close the extension tab
How to use Vanilla Cookie Manager
Once this extension is installed, an icon will be added in the right hand side of the address bar, next to the favourites star icon.
Clicking the icon provides a dialog for quickly adding the current site to the whitelist. It also gives an option to delete unwanted cookies (any that are not related to your whitelist).
After adding a site to your whitelist, the diagonal line through the icon disappears, indicating that you have allowed cookies for that website.
Right-clicking the icon provides further options for managing your whitelist.
Firefox, by default, allows cookies to be set by all websites. We advise installing the “Cookie Whitelist” extension so that you can control which websites can save their cookies on your system. You only really need to allow cookies from sites that you want to interact with, such as sites that you need to log in to for shopping, banking, webmail, facebook, etc.
Installing Cookie Whitelist
Tools > Add-ons
In the Search box on the top, right of page – type cookie whitelist
Find “Cookie Whitelist, With Buttons (if you don’t see it click See all results at the bottom) and click the “Add to Firefox” button next to it
You will be presented with a
box – click the Install button when it’s ready
How to use the Cookie Whitelist buttons
Once this extension is installed, two buttons are added to the top of your browser to allow easy control over cookies.
The Add (+) button adds a dialog for quickly adding the current site to the whitelist. Green indicates that the site is not yet listed in the whitelist; grey indicates it has already been added and can set cookies.
The Record (red) button allows Firefox to temporarily accept cookies from any site not on the whitelist. These cookies will be deleted when Firefox is closed. This makes it much easier to deal with the occasional sites that refuse to work without cookies.
Right-clicking on either of the buttons enables you to manage your whitelist and any currently stored cookies. It also allows you to choose whether or not to allow third party cookies (best to generally say no to these, although you may need them for a small number of sites; trial and error prevails here, I’m afraid!)
