Wifi routers usually specify the regulatory rules for all devices connected to their network. In rare cases a router may go rouge and specify the wrong regulatory domain, which might effect the quality of the connection and at times may make the network unreachable even if the network says that its connected.
Below are the debug messages from the command “dmesg” in one such case:
Sometimes when websites are updated,they tend to change the way they manage cookies. What happens then is that there is a small possibility of certain parts of the website not functioning as the old cookies remain in the browser. In those cases the best approach is to remove the errant cookie and let the website recreate the cookies.
Here is a quick tutorial on how to do that:
Firefox:
After a crash Firefox, when restarted gives a page with the option of Restoring the session or Starting a new session. Sometimes in haste we might hit the “New Session” option and feel a bit stupid that all those open tabs are now gone…
Well there is a simple way to undo that. Simply point your browser to “about:sessionrestore” and you will get back to the page with the option of restoring your previous session again!
Protecting your original video content from unauthorized re-uploads and branding your creative projects requires a clean, professional watermark. If you are using Kdenlive—the powerful, free, open-source video editor—adding a custom logo or a transparent graphic overlay to your timeline is incredibly straightforward.
Whether you are trying to insert a corporate logo, a social media handle, or a semi-transparent text overlay, modern versions of Kdenlive handle this using the built-in Transform effect ecosystem.
In this guide, we will walk through the exact pipeline to import, overlay, position, and blend a watermark onto your video project without degrading your timeline’s playback performance.
Before touching the timeline, ensure your watermark or logo is formatted correctly:
By default, Kdenlive will display your logo at its full native resolution, which usually crams up the center of the viewport monitor screen. We will use the Transform effect to downscale and anchor it neatly into a corner boundary.
10% and 20% depending on your asset resolution properties).40% and 60%.Once the design layout satisfies your aesthetic needs, you are ready to compile the final binary file:
To make a watermark look professional, use a transparent PNG logo and apply the Transform effect to scale it down to around 15%. Crucially, reduce its Opacity setting to between 40% and 60% so it blends softly into the video background.
Why does my watermark graphic have a solid black background in Kdenlive? This occurs if your logo asset was saved as a standard JPEG or flat format lacking an alpha channel. Re-save your graphic design asset out of an image editor as a 24-bit transparent PNG file to remove the solid background bounding blocks.
Does adding a watermark slow down Kdenlive rendering export times? Because the Transform scaling and opacity adjustments require very little computing mathematical computational power, adding a static watermark track overlay introduces virtually zero performance degradation or added file render processing times.
Phatch is a simple to use cross-platform GUI Photo Batch Processor which handles all popular image formats. Phatch can batch resize, rotate, apply perspective, shadows, rounded corners, … and more in minutes instead of hours or days if you do it manually. Phatch allows you to use EXIF and IPTC tags for renaming and data stamping.
Phatch is an incredible tool to quick fire batch processing of photos. I use it most commonly to resize images to a fixed size, for example while uploading images its preferred to have a good resolution but not as high as what the digital camera provides. I use Phatch to reduce the resolution of the photos in the photo set and then upload the images. This saves a lot of time and bandwidth.
Using Phatch is simple but might confuse a newbie. Here is a simple startup guide to Phatch.
To install Phatch on Ubuntu, use the following command:
sudo apt-get install phatch
You can download the installation file for Windows and other Operating Systems here
