Open 4 web browser windows in full-screen mode each in 1/4 of the screen

I regularly have some webcams open on one of the monitors of my computer. I would like to be able to open them in full screen mode, but have each “full screen” be only 1/4 of the whole screen.

Here’s how I view them at present:

enter image description here

I would like to have each webcam run in full-screen mode so that I get larger pictures and avoid wasting screen space with all the window frames, toolbars, etc.

Is there any way I can do this? My web browser of choice is Google Chrome and I’m using Ubuntu 18.10

NB I have a second monitor connected to my computer too, so any solution needs to take that into consideration too.

Browser cache not clearing regardless of meta tags

So, the problem is as follows. I am trying to make a small html page update to the latest version on server while it is loaded. I have gotten to the point where I am just trying to make this work, with a page as barebones as it can get. I have tried this on firefox, internet explorer and microsoft edge, all with the same results.

<html>  <head>  <meta http-equiv="cache-control" content="no-cache"> <!-- tells browser not to cache --> <meta http-equiv="expires" content="-1"> <!-- says that the cache expires 'now' --> <meta http-equiv="pragma" content="no-cache"> <!-- says not to use cached stuff, if there is any -->   </head>  <body> testing cache update - 4 </body>    </html> 

This is the entire sourcecode of the page, and no matter how i tweak the meta tags, i -always- have to hard reload with ctrl+f5 to get the latest version of the page (i tweak the text in body) to show up.

Does anyone have any idea what’s going on here, and how i can make my page always load the latest version?

Compile Jelly browser from source

I really like the Lineage OS browser, Jelly. I would like To have it on my phone (Galaxy J5 2016 – Stock) but I cant find it on Fdroid, Play store or on Lineage website as apk. I Just found the github page : So I tried To compile it from source but When I Try To install on my device it says : failed to parse the package . After that I searched a little bit deeper And I found this but it is discontinued and I can’t find the source code. Why isn’t it available as an apk? Does it require some Lineage libs or APIs to work?

Any help would be really appreciated !

I keep getting a fatal error from my browser when trying to create a user

Is there such a thing as an ‘audio browser’ for managing audio files?

I use gThumb for managing photos and video, because it’s the only manager I’ve found that quickly loads thumbnails for both photos and videos. But I also have a lot of raw field recordings I want to manage.

It would be nice if there was a program that could browse audio, where I go to a directory and it shows me a list of wave forms, with running time, file name and file size.

Like a camera, a field recorder gives your files a filename using the date, time and a serial number. So the filename doesn’t tell you anything about the content of the file. Playing the file in VLC might not tell you anything, either, because your recording could be mostly silence.

The advantage of an audio browser is that you can see the audio, visually. You could click on some transients, halfway through a 40 minute recording, and listen to the audio that way.

Is there any such program in Ubuntu?

Is there a reasonably straightforward way to download videos from proprietary web browser players?

I have a Samsung SM-P900 tablet that I bought specifically to watch professional education videos during a long commute. Unfortunately almost immediately after that the videos I want to watch the most, generally relating to statistics and R programming and hosted on the RStudio website, switched from an easily downloadable format to hosting via the Wikia media player. I have been able to download a handful since then by looking at the page code, but it is a lot of work and the rules keep changing, and I have not been able to download the more recent videos to either my tablet or Windows machine with any amount of effort. I’ve faced similar problems with the JW Player and a few others. All of these videos are free and I want to download them solely for my own use.

My question: Is there a reasonably straightforward way, perhaps involving an app, of capturing such videos that works consistently over time and across players? It seems like there’s got to be a way to interpose a (software) recording device between the player and the screen, but I have not found it. It might need to reassemble streaming video from the pieces that arrive.

My OS is the Resurrection Remix versin of Android 7.1.2.

Is data between keyboard and web browser secure from local computer applications?

My question is about the text that I type on a keyboard while in a web browser. I understand that if the website has HTTPS the connection from my browser to the website is secure/encrypted, but what about the text that I type on the keyboard on the local computer?

For example, at an internet cafe, if you open a Chrome window and go to a secure site (HTTPS) is the text that you type on the keyboard secure from the keyboard to the browser? Can key logging software on the local computer access the text?

My concern is logging into my email account (or any other private account) on a public computer, can the password that I type be intercepted? If so, is there any way for a user of a public computer ensure the privacy of their password in this scenario?

How to best combine browser and custom autocomplete functionalities?

When creating address forms, it is a common practice to provide autocomplete functionality for city and street names loaded from some external API. How to best combine this with built-in browser autocomplete="on"?

What I find on the internet forms mostly is just turning the functionality off, let’s take website for an example:

enter image description here

I personally think it is an antipattern, as a user with his autocompletes settings set up to some extent – all rental, work, and home addresses added & used whenever possible.

What I think is a solution (didn’t check if that actually works yet, it’s just planning phase):

  • custom autocomplete API call starts at 3 characters (city / street)
  • focus on an empty input – browser autocomplete is on
  • starts typing and reaches 3 characters – browser autocomplete turns off and is replaced by the custom one

What do you think of my approach? Do you have anything better in mind? Do you know any website where these functionalities are neatly combined?
