QUESTION
My intention is to find the employee with second highest salary from all the employees of department 'admin'(case-sensitive). Display the employee name with his/her department. If there are insufficient records, display relevant message.
...ANSWER
Answered 2020-Aug-16 at 08:50you were close, but I think you don't need grep
since you can "tell" awk
to do the following action only if the third field is "admin", so we can use a variable, n
, to store the number of "admin" records examined (numeric variables in awk defaults to 0), if the current is 2, print the record and exit. at the END
if the number is still less than 2, print the message:

QUESTION
I'm trying to write an NSIS script using MUI2 and for some reason it refuses to show an image on the welcome page. I have tried using MUI_WELCOMEFINISHPAGE_BITMAP as instructed in the NSIS wiki and manual. I have used ${NSISDIR} to reference the included bitmaps. I have tried using a full path to the included bitmaps. I have tried using a path to a bitmap in my installation files directory.
No matter what I do, I end up with a Welcome page that has a title and text, but no image. The build process gives no warnings or errors concerning the welcome bitmap. The installer installs everything correctly. There's just no image on the welcome page and I cannot figure out why.
This is my first attempt at using NSIS, so there's probably something I'm missing. The section of my .nsi file with the page definitions is below. Any help would be appreciated.
...ANSWER
Answered 2020-Jun-27 at 03:28I found the solution and am posting for anyone else experiencing the same problem.
In short, the answer is: !insertmacro MUI_LANGUAGE "English"
Apparently, one must specify a language for a bitmap to show up. Makes total sense, huh? And yes, Virginia, that was sarcasm.
I figured this out by taking the example from the website below and commenting lines out until I reproduced my problem with the lack of a bitmap image appearing on the welcome page.

QUESTION
I'm struggling with implementation of a function that I define in my header file of my c++ program. I think I am misunderstanding how it works, but most reading on the web doesn't spell it out clear enough for my peon brain to understand.
I'm trying to make a 'sort_name'
function that sorts an array of private classes based on the c-string "name"
when the function is invoked.
Unfortunately I keep running into errors when trying to use it.
Here's my courses_main.cpp's
main function:
ANSWER
Answered 2020-Feb-14 at 22:58A better code organization would be to declare the functions in the .h
file and implement them in the.cpp
.
Here is a working sample without .cpp
for simplification. Only Courses.h
and main
.
With .cpp
your program should be somethong like this:

Whatever user have for role_id, method always shows certain role's name, in this case "moderator". Don't know what is wrong with it, or at least i can't see it ...
Here is User model:
...ANSWER
Answered 2019-Jun-09 at 01:14Well, I think the problem is in your rola()
function in your User.php file: you are defining a foreign key to the belongsTo
relationship which here is id
.
It should be role_id
as this is the key Eloquent would try to map to the id
of the Roles' model. See the documentation for more informations
QUESTION
I am trying to spin up a Web Worker from inside a Web Worker using Chrome. Historically, this has been a problem space with the Chrome Host API, but:
According to ChromeStatus,as of 2018-10-22
Dedicated workers can create nested workers, but shared workers and service workers cannot.
Creating a nested dedicated worker from a shared worker is not yet supported.
Nested shared workers are also in the spec, but there is no plan to support them at this time.
Lucky me; I'm using a dedicated worker.
I can find no information available that formally contradicts this declaration of support in Chrome for desktop release 69 (I am using Chrome 72) and my nested Worker just sits on his duff and refuses to get Janice her Coffee.
I have three moving parts at play: a SlaveDriver, a Minion, and a Peon. The SlaveDriver delegates to the Minion. The Minion delegates to the Peon, the Peon does the work, and each receiver takes the credit.
SlaveDriver
...ANSWER
Answered 2019-May-20 at 14:12The answer to my question is currently found in the Spawning Subworkers subsection of the MDN documentation on Using Web Workers
Workers may spawn more workers if they wish. So-called sub-workers must be hosted within the same origin as the parent page. Also, the URIs for subworkers are resolved relative to the parent worker's location rather than that of the owning page. This makes it easier for workers to keep track of where their dependencies are.
Ultimately, the problem that I experienced was rooted in the fact that when my minion worker attempted to spawn its peon, it attempted to make reference to a file that was relative to document root rather than from the context of the worker but nothing was output to the console indicating that the file did not exist.
To tie this simple example out:
