@dessert Typing "20, EE, 12" is not as quick (or easy) as typing "20 T" for 20 trillion. Plus when you enter "20 T / 50m" the answer is displayed as "400 K" which is easier to read than "400000" Additionally (no calculator pun intended) an answer like "512 P" is easier to read than "512000000000000000"
I am trying to install some software in an old version of Linux (the updated software for 18.04 is unstable, the older version seems to be better). However, the code I used way back to install the packages for 18.04 is not working for ubuntu 14.04.
The code I'm am using is copied below

@WinEunuuchs2Unix I think you're onto something. Look if you can patent it, have it made in China and when you're rich and famous, send your jet over and invite us to Caviar and Vodka!
Doesn't really matter @Fabby. I developed new technique of creating ISAM B-Tree indices off of flat files. A few years later Google came out with indexed search engine for internet. Stole my idea :(
@WinEunuuchs2Unix yes, but it‘s nothing with trillion or billion, and you don’t say 15 Tera dollars – that’s not human readable when talking about dollars, people, cars, …

I am trying to run an install script for Gazebo, which first tries to get the gpg key from keyserver.ubuntu.com. This fails with the following message:

Other answers online suggested this error occurs when accessing the keyserver from b...
@Fabby Please help to reopen this question. I got the accept vote for answering it, and it was bogus closed as off-topic anyway.
I also got a comment below the same question that says it was bounty worthy. Bounty worthy from my commenters often equals automatic close votes from my reviewers.
I got the bounty worthy comment below my accepted answer obviously because I didn't ask that question, only answered it.
Hello, I need help closing a named pipe. Can anyone please help? So, I created a named fifo via mkfifo myfifo, then some C++ executable files wrote/read from myfifo, and now I wish to close it (so I can cat its contents). However, I read the man page and also googled around but cannot find any specific command to close the fifo (even after all executables are done)
Hi @Fabby, sorry i did not post this on the mainsite because I think this is a very short query, and I am afraid someone will point me to an existing resource that i cannot find with my poor google-fu. I am using Ubuntu 18.04
@GaurangTandon Please post a question on the site, include all relevant information and then post the link to your question here pinging me and I'll ping some other people if I can't resolve the issue.

Ah yes. I should learn to read the transcript more closely.
@GaurangTandon please show us all the commands involved. We need to see mkfifo myfifo, then whichever command you used to write to it and then the cat you tried.
@GaurangTandon I mean, pelase add these commands to your question. And make sure to just paste the commands, not a screenshot of them, so we can read them easily and copy them.
@vidarlo I really felt it read as very pretentious and condescending.
Feel free to roll back, but it was the main reason I objected to your answer. It reads like "what you want is pointless, listen to me I know what is correct".
@terdon That may very well be, but that doesn't really change the fact that scientific notation is the correct way - and the pretentious and condescending nature probably has more to do with me than numbers... :)
@vidarlo It is a correct way, not the correct way. It's the correct way if you're working in science, but not if you just want to calculate millions. Don't get me wrong, I use scientific notation daily, but telling someone that the answer to their question of how to use X notation is to use this completely different notation isn't very helpful IMO.
I installed Ubuntu 18.04 on my old laptop and whenever I want to play a downloaded movie, it will stop around the middle, start buffering and continue from way earlier. I tried with SMPlayer, VLC, Baka MPlayer and even with Kylin Video (which as I see is a fork of Deepin Movie) but none of them w...
Is there any way to close a specific tab using an Ubuntu terminal? I have read that Firefox treats all tabs under one process so I have switched over to Chrome for more flexibility since each tab is treated as its own process. I am creating the tabs also in terminal using -xdg and I see they are ...
@PerlDuck Seems you follow the habits of our (always hungry) friend @Fabby : always think about what can be eaten next ... hahaha ... no, joke aside : Bon Apetite ! Enjoy the soup ! :)
@cl-netbox I'll hopefully do. It's a typical German winter meal: savoy. Sounds glamorous but is just a kind of cabbage. Why did they name a hotel after a cabbage after all?
@Zanna “Drive safe!” or rather “Drive safely!”? The latter is correct in my perception, but the former could be interpreted as an elliptic “Drive staying safe!” or the like.
Perhaps I should file this as a bug report, but at the moment I would just like to hear some theories on how this might have happened, as I'm not even sure it is a bug or just me misunderstanding things.
I was running Ubuntu Server on an mdadm RAID1 volume, and because ran into some problems I d...
