Ubuntu

Corona688 / DGPickett, thanks for your assistance.
It is true that a one should expertise things practically rather than just reading about them. But sometimes we have to get the initial supports to just know the first steps in order to start walking and running alone later on; thanks DGPickett for your useful advice.

Hi,

You are looking only for hardcover books? not ebooks??

I find this one is very interesting...
Please google for "Ubuntu Server Guide"
it will give official Ubuntu Server Guide.

(PS - as i am a new member, i cannot post a URL. i will reply the URL later.. .thanks..)

Hi Sekar,
thanks very much for your helpful advise.
I'm now searching for the suggested guide e-book.

I find it helps to have a project to get me to learn! When you are lucky, an employer rewards you for completing the project! Not much use for SQL around the house (but now I am moving my personal finances to GnuCash with MySQL :-).

DGPickett,
I agree; we should learn practically which is more important than reading theoretically.... but who would accept a newbie employee??? they're too rare I think...

regards,

I am big on a Proof of Concept (POC) demonstration of alternative technologies, so I can get into technologies not in my original job description. Then, I have processional experience when I leave. Not a web developer? Put up some useful web services to help yourself and the group. Not a C/JAVA/PERL guy? Write some useful tools, reports, in your new language and share them around. Developers can get what they need free in the world of open source, or write a new whatever from scratch. It might be better than the original. I wrote uniq and comm in C before I discovered their names. My last uniq was better, a sort-free home-brew binary tree tool that also does aggregates:

Code:

$ aggsx --help
 
Usage: aggsx [ -b ] [ -l ] [ -p <prefix> ] [ -u ] [ -d ] [ -h ]
 
Computes the count distinct, count null, min, count of min, max,
count of max, average (mean) of not null values if numeric,
median of not null values, largest of the most popular values,
count of that most popular value.
If -l is present, first prints out all values in order and their counts,
null last, but no aggregates.
If -b is present, prints out like -l and then prints aggregates.
If -p is present, the aggregate is prefixed with '<prefix>|'.
If -u is present, just immediately prints out unique values.
If -d is present, just immediately prints out duplicated values.
If -h is present, prefixes values line with header line:
CtD|CtN|Min|CtMin|Max|CtMax|Avg|Med|MPop|CtMPop
 
$

I should add an argument to set the null string, currently hardwired for Interbase/firebird '<null>'. https://www.unix.com/shell-programmin...roup-unix.html

You can get certified in the various LINUX/UNIX/Language skills, and get hired with them as 'nice to have', an edge on the competition, in a less skill-intense area than development.

Thanks DGPickett for all your efforts,
I appreciate Vmuch the helpful info provided
