‘whoami’ returns ‘root’ – how do I set myself up as user?

Just installed Ubuntu on Windows 10, I am a total beginner and new to this and I did see the prompt to provide my username, but by the time I found out what my username was (which had to match Windows apparently), that prompt was gone and never came back. pwd returns ‘/root’, and whoami returns ‘root’. Help – I don’t een know how to google these things! 🙂

Can any one tell what is the problem??

speaker-test returns all 6 channels to front speakers

OS: KUBUNTU 19.04 Soundcard: Creative Soundblaster ZxR Sound Setup: front (left/right), center, bass, rear (left/right)

My problem is, that all speaker outputs are played at the front speakers.

I did the following:

  • Set speaker setup at Plasma sound settings to “Analog Surround 5.1-Output + Analog Stereo-Input”
  • If I click on any rear speaker there, to test audio output, they are played on front speakers. The setup seems very faulty:
    • rear right: output on front left and right at the same time
    • rear left: output on front left and right at the same time
    • center: output on front left and right at the same time
    • front left: output on front left (one of two correct speakers)
    • front right: output on front right (one of two correct speakers)
  • I then executed alsamixer and noticed that my NVIDIA Graphics card was initially selected. I switched with F6 to my ZxR and set it up like this: enter image description here
  • I ran speaker-test -Dplug:surround51 -c6 -twav. An error message appeared and I was unable to perform the command: Error when opening the device: -2
  • I googled how to set the default device and so I did cat /proc/asound/cards:
 0 [NVidia         ]: HDA-Intel - HDA NVidia                       HDA NVidia at 0xdf080000 irq 17  1 [Creative       ]: HDA-Intel - HDA Creative                       HDA Creative at 0xdf204000 irq 19 

with kate ~/.asoundrc I set my default device:

defaults.pcm.card 1 defaults.ctl.card 1 defaults.timer.card 1 
  • after a restart speaker-test -Dplug:surround51 -c6 -twav was working: Unfortunately rear left output is on front left, rear right output is on front right, center appears to be on both front (left/right) speakers

Does anyone have any idea how I can fix this?

Clicking on an Enterprise Wiki Category link only returns the current page

In Sharepoint Online, I have an Enterprise Wiki that I created using CSOM.

I have a term store and on each page there is a Categories section which shows terms: enter image description here

When I click on one of these, I would expect to see a list of all the pages with the same term/category. But I only get 1 result: The page itself:

enter image description here

I can add new terms to the ones that were created with CSOM but they behave the same.

Using the Term Store Manangement Tool everything looks normal: enter image description here

Why don’t I get the list of pages that I expect?

preflight returns 401 response even though headers correct

I am trying to access a sharepoint server REST api to upload some files. Access is via our tomcat application

Although I believe I setup correctly the headers in IIS the request does not pass the preflight.

Here are the request headers:

Request OPTIONS /_api/contextinfo HTTP/1.1 Accept  */* Origin  http://localhost:8080 Access-Control-Request-Method   POST Access-Control-Request-Headers  content-type, accept Accept-Encoding gzip, deflate User-Agent  Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; MAAU; rv:11.0) like Gecko Host    temp-sharepoint Content-Length  0 Connection  Keep-Alive Cache-Control   no-cache 

and the response headers:

Response    HTTP/1.1 401 Unauthorized Content-Type    text/plain; charset=utf-8 Server  Microsoft-IIS/7.5 SPRequestGuid   8d690d9d-d06e-101d-6038-8056a7fce7c2 request-id  8d690d9d-d06e-101d-6038-8056a7fce7c2 X-FRAME-OPTIONS SAMEORIGIN SPRequestDuration   5 SPIisLatency    1 WWW-Authenticate    Negotiate WWW-Authenticate    NTLM X-Powered-By    ASP.NET MicrosoftSharePointTeamServices X-Content-Type-Options  nosniff X-MS-InvokeApp  1; RequireReadOnly Access-Control-Allow-Origin * Access-Control-Allow-Credentials    true Access-Control-Allow-Methods    GET,PUT,POST,DELETE,OPTIONS Access-Control-Allow-Headers    accept,content-type Date    Fri, 05 Jun 2015 15:52:01 GMT Content-Length  16 

My code to request

var url = sharepointURL + "/_api/contextinfo"; jQuery.ajax({      url: url,      type: "POST",      headers:       {         "Accept": "application/json; odata=verbose"      },      xhrFields: {             withCredentials: true     },     crossDomain: true,      contentType: "application/json;odata=verbose", 

Why is not passing the preflight? have I misconfigured the headers?

FindRoot returns the initial guess (Having large magnitude)

In my program (Big Enough, no need to see, pasted here : https://pastebin.com/HqnskRdn), I am trying to find the root of equation by FindRoot in range of order of $ 10^{12}$ or so. but FindRoot returns the initial guess,

Now if I change the coefficients of equation slightly then also, It returns the initial guess.

Ex- Initial Guess: $ 1.06154*10^{12}$ , Answer: $ 1.06154*10^{12}$

Any way out please ?

systemctl Service that runs an executable that never returns

I’m having some trouble figuring out how the services work on CentOS. Right now I have the following service file:

[Unit] Description=SelfTester After=network.target  [Service] Type=simple ExecStart=/usr/bin/selftester  [Install] WantedBy=multi-user.target 

This will launch a script that calls an executable that will never return:


The executable never returns. When I launch the service, it runs for a while but then exits due to timeout:

Job for selftester.service failed because a timeout was exceeded. See "systemctl status selftester.service" and "journalctl -xe" for details. 

Thanks inadvance
