I am using Ubuntu 14.04. With Skype Linux version 4.3.0.37 when I try a conference call, my friends can hear me, but there is no video. They receive a notification saying I need to upgrade Skype. There is no problem for a simple video call. Both audio and video work perfectly. I have downloaded Skype from . The Skype website don't have any recent updates for Linux distributions.   Any help on how to solve this?
For those who duplicated my previous question - ; am NOT asking how to install Skype for God's sake!!   The question was rather - I already have Skype installed, the thing is there is no possible option for me to do group video call or group screen share. The interface itself resembles the times when Skype was newly born. While on Windows, Skype's latest version is around 6.(something), here it's only 4.3. In Windows group video call is now free on Skype, here I can't even do video call! I think this is a major drawback for an otherwise so good OS! Is there anything that can be done about it?  Thanks for any help!  For those who don't have an answer for me, I still thank you for at least understanding my question!!  Have a good day!
What was the meaning of the Night King's message? In S08E01 of Game of Thrones, we see this message:    We have seen this several times, the symbol drawn with horse heads, the stones around the Weirwood where White Walkers are created and in some caves, drawn by Children of the Forest.  Do we know the meaning behind this symbol? Does it or something similar occur in the books as well? If $I_n=\int _0^{\pi }\sin^{2n}\theta \:d\theta $, show that $I_n=\frac{\left(2n-1\right)}{2n}I_{n-1}$, and hence $I_n=\frac{\left(2n\right)!}{\left(2^nn!\right)2}\pi $  Hence calculate $\int _0^{\pi }\:\sin^4t\cos^6t\:dt$  I knew how to prove that $I_n=\frac{\left(2n-1\right)}{2n}I_{n-1}$, but I am not very good at English, what does it mean Hence $I_n=\frac{\left(2n\right)!}{\left(2^nn!\right)2}\pi $ do we need to prove this part as well or is it just a hint to use? and for the other calculation to find $\int _0^{\pi }\:\sin^4t\cos^6t\:dt$ is there something in the first part that I can do to help me solve this question because otherwise it becomes very long and it's part of the question.

Calculating with Mathematica, one can have $$\int_0^{\pi/2}\frac{\sin^3 t}{\sin^3 t+\cos^3 t}\,\mathrm dt=\frac{\pi}{4}.$$   How can I get this formula by hand? Is there any simpler idea than using $u = \sin t$?     Is there a simple way to calculate $$ \int_0^{\pi/2}\frac{\sin^n t}{\sin^n t+\cos^n t}\,\mathrm dt $$ for $n&gt;3$? Could anyone come up with a reference for this exercise? I need to write a small program that can detect that it has been changed. Please give me a suggestion!  Thank you. Why do investors pay trillions for minority stakes in companies, when their only potential payback is modest uncertain dividends? I'm struggling to understand the core reason to invest in stocks as a minority shareholder. Majority shareholding makes more sense as you effectively control the company, so you can pay yourself dividends or even sell the entire company at will. You can guarantee your own payback.  However, as a minority shareholder, you don't get to make any of these decisions. You're basically just hoping to eventually, some day get paid, if the majority holders decide so.  Why do so many investors agree to pay now huge sums of money (trillions in total) for something that may eventually pay dividends, and even in the best case, these dividends are only a fraction of the price you paid to acquire these stocks?  The average annual dividend rate for the US stock market is 2%. That means if you bought 100 million worth of shares, you'd have to wait 50 years to recover your investment.  Of course, the most probable way you'd eventually get liquidity for these shares is by selling them to some other starry-eyed investor - which makes the whole thing seem like a giant Ponzi scheme.  Given all that, it's unclear to me why the public is willing to spend so much money to acquire minority shares in companies. Determining if trees within forest gaps are clustered using R?

What character / attack / stage combination can get me a combo of 100? For the first two challenge panels, I just used my golden hammers on the "get a combo of x," but now I'm seeing on challenge panel 3, the game expects you to get a combo of 100! I can barely get past a combo of 9 without the counter resetting. What character / stage combination can get you a combo of 100? Are there multiple, so I can more easily get the "get a total combo of 400 across all characters" challenge?  Additionally, what exactly constitutes a combo? Sometimes my combos are cut short and sometimes they're longer, so I must not understand how they're tracked. What new capabilities do user-defined literals add to C++?

Does someone knows if it exists some ppa packages source for the newest Ubuntu version 19.10 i had problem with that when i upgraded from Ubuntu 19.04 to 19.10 i didn't work? There is a restriction on setting your birthday:     Oops! There was a problem updating your profile:   - Birthday must be after 1920/01/01   I realize the number of 90 year old users is small, but shouldn't the restriction be a bit more relaxed, such as larger than any ?  Either 120 or 150 seems appropriate.  For example, my grandfather turns 90 next year (and just barely misses the current cutoff), but I can't imagine he's the only one around that age who is computer literate and still active enough to be interested in (the increasingly broad range of) SE sites.  I don't think he has contributed yet (mostly because of the comment restriction, I'd see him commenting before asking or answering), but I have emailed him with links that I know he's read.  Incidentally, the error message is wrong: birthday must be after 1919/12/31 and using the next day is accepted. Is there any way to tell Google to use a particular account for all Google services by default? I typically use 2 Google accounts simultaneously in my browser. So whenever I fire up any Google service like Google Maps or YouTube or Google Search, it uses one of the accounts. The problem is that I don't want that account to be used and no matter how many times I switch the account for these services, they seem to default to same account.  Is there any way to tell Google to use a particular account for all Google services by default?    I am not talking about using Google account to sign in to third party websites. I am talking only about Google's own services.  I am using Chrome if anyone is going to suggest client-side solution.
