Q: FFT -> a simple algorithm to compute a derivative?

8:26 AM

It may be a wrong forum; if so give me a proper pointer. I use a lINUX SYSTEM (UBUNTU, 12.04) a standard FFT package (DFFTPACK for slatec -- sorry, I am a dinosaur -- based on gfortran now), and have used various simple algorithms for computing derivative based on FFT. However all of them give me...

Q: Alias to prompt for tab completion for a set of directories?

10:16 AM

Is it possible to make a bash alias, which would be able to prompt me for tab-completion of a set of directories? let's say I have a number of source code controlled projects, main path of each located under ~/projs/<projname>/trunk Now, I have created a Bash alias, which allows more convenient...

Q: Ubuntu / XFCE: Nautilus not opening files

11:03 AM

I recently had my office PC upgraded from ubuntu 14.04 to 18.04, with the XFCE interface (v4.12) installed. I dislike the standard file browser (thunar) so used one of the answers to this thread to change to nautilus. That worked and nautilus opens now when I double click on a folder. However, n...

OK, where do I request a bot to be added to chat ? I need a reminder bot to ping me about revisiting posts

Seriously, SO needs a "remind me about this thing in x hours" feature somewhere. Or am I supposed to write one myself ?

Nevermind the fact that I've no clue about javascript

@SergiyKolodyazhnyy maybe a good question to ask the guys at Charcoal HQ where and how to.

Sergiy Kolodyazhnyy

Yeah, could try that. My initial reaction is always meta and tag the post with feature-request tag

Anyway, I need sleep

sleep well :)

Member for 7 days but one question was asked way back in 2013. Is it a glitch or is there something I'm missing out?

Q: Concurrent requests from node.js process are far too slow - is the OS limiting them

4:49 PM

I have a node.js script, it makes a http request to a url N number of times using two different techniques. First it does it serially, then it does it using the node.js Promise api (all the requests go off at nearly the same time and we wait for the responses back). If I run this script on my ma...

Not sure if you just want to rant or if you have an actual question. As it is right now your question is far from being able to have a professional discourse on it. Also writing in all cats means in general that you are shouting which is considered rude. So best if you really want your problem solved use the edit button to shape your question into a more meaningful manner. Please consider that all users on this side are not employees of Canonical or otherwise are paid, They are users as you are which spend time of their day to help others. Thank you. — Videonauth 29 secs ago

@Videonauth Hmm. I didn't know you could write in all cats! :P

@terdon yeah grml, I just seen that too after the edit grace period

:) seems were all not perfect

@terdon you have the font for that too?

O_o

(or maybe I just googled "cat font", but you'll never know)

@terdon the question is, is it rude to write in all cats?

@Zanna Pretty sure the cats will think so, yes.

I think for questions like these askubuntu.com/q/1120244/231142 we need to have a "Because" tag or answer button. :)

Wow, this guy’s U&L profile puzzles me: He has 27k rep, but only 16 answers, none of which has a vote score higher than 3. On the other hand he has 1,331 questions, the most upvoted one with a score of 487. How do you come up with so many questions (and some really good ones!) and yet have so few answers? (I don’t want to judge, I’m just wondering.)
