Basic Linux "code", etc.
 
Hi! :hattip:

A lot of folks have talked about the linux operating system having a code which starts it running and it's given away FREE.

Is this basic program like a series of DOS batch files? I did a lot of that in DOS 6.22 and plan to use it on my in-house system, along with THIN CLIENTS.

Using the Thin Client should help block the rf egress
out of my ham shack, and not bother my recievers and scanners. It should be easy to hook up with just Cat 5 cable or should I use RG-59, 72Ω, copper-sheild coax and some BNC connectors, LOL!

Well, I woke up from some good sleep. Think I'll go back to bed and try to get some additional sleep.

GOD BLESS,
Best Regard,

Buck/KA5LQJ

code which starts it?? A boot loader? No idea what you mean there., there is no "basic program". As for "free", yes most distros are freely available start to finish.

The Linux kernel itself is written in c, and many additional scripting and programming languages are also involved in the running of it and it's applications. there is no obvious reason to associate it with DOS in any way over other operating systems.

And your god can keep his blessing, thanks anyway.

I'm also not sure what you mean. Do you understand anything about open source and/or computer programming?

It would if the primary source of RF was the HDD because AFAIK a thin client is pretty much a computer without the HDD so there's still a PSU etc.

How much RF is coming out of your computer? AFAIK computer cases are either metal or plastic internally coated with a conductor, intended to stop electromagnetic radiation including RF ... ?

The source code should be freely available from the makers of the individual programs.

Some Linux distros distribute the source code with the distribution; if they do, it's often placed in /usr/src. Others include it on the installation media but do not install it to the computer by default; others make it available for download from the repositories.

I know that current Slackware comes on six CDs. Two of them are devoted to source code (or "sources" as it's commonly referred to).

I think I read somewhere that most of it is in C++, but I can't find a cite for that right now.

frieza 10-22-2011 09:05 PM

the code which you are referring to is the 'source code', which is the human readable version of the software that makes up the Linux operating system (by human, I mean programmer), most of the time when you are running software you are dealing with 'object code', which is the 'source code' translated (compiled) into machine language instructions for the computer to execute.

The Linux kernel is written in a mix of C and some architecture specific assembly (which you would find in the 'arch' directory of the kernel source tree) for specific parts of an operating system that can't be handled in C.

other programs in Linux are written in a variety of languages from C to C++ to python and ruby being the most common, though other languages do exist as well.

The difference between Linux and say, dos or windows is that for Linux, the source code is freely available, whereas with Windows/Dos , only Micro$oft has access to the source code.

as for dos batch scripts, Linux has shell scripting which is far more capable than dos batch files.

As far as I know, youare more likely to get RFI/EMI from the HDD cables than from the HDD itself.

You might some some useful info/tips on this page-

(Linux is Not Windows) refers to the GNU/Linux OS and various Free & Open-Source Software (FOSS) projects under the catch-all name of "Linux". It scans better plus a Great Article.

Comparison of Windows and Linux is comparisons between the Microsoft Windows and Linux computer operating systems are a long-running discussion topic within the personal computer industry.

CAT5E Shielded is doable but do not forget the plug.
Quote:

excerpt from Shielding Cat 5 Cable
There are a variety of different methods used for shielding Cat 5 cable. The reason for adding a shielded layer to network cable is to minimize the interference with network signals. Adding a foul shielding consists of wrapping to plain aluminum mylar layer around conductor pairs. This shielded layer provides protection from EMI/RFI interfering. This method doesn’t, however, provide the most sound protection for all the frequencies , despite the fact that 100% of the cable pairs are covered by foil:
Another method of shielding Cat 5 cable is by using a braided shield. When your cat 5 cable demands more flexibility with this technique, a smaller percentage of the network cable is covered. The braided shield has a crosshatch design which offers stronger protection from interfering elements. The braided shield is extremely durable and can withstand the cable being flexed constantly.
Your LAN devices can emit allowable interference(FCC), check the specs for each. Unless you place your equipment within a Faraday Cage there is going to be emissions. Plus remember the CAT5 cable is twisted pairs, then adding the shield will aid in limiting the interference between pairs and localized. You can get commercial shielded cases for your computer system but remember the external devices are the culprits. A shielded Laptop would be the best but at the cost $$$.

I have a very deep, personal and private walk with THE CREATOR. I won't tell you how this is, unless you ask and then I let YOU decide if that's what YOU want. Each relationship with HIM is different, according to your needs.

I'm going to continue to use GOD BLESS because I simply want the best for everyone, no matter where they are, what color their skin is, what 'religion' they profess or don't at all. I respect everyone and their opinion.

If you respect me then please don't associate me with your beliefs then. I personally find it offensive.

So, let's recap: You 'respect' everyone...then promptly ignore everyone, and do as you wish, no matter if it offends them or not?

Yeah...makes perfect sense. I'm with acid_kewpie on this...this is LINUXquestions. Has zero to do with religion of ANY sort, and leaving it out of ANY discussion here would be best for any concerned, no matter the context or intent. There are PLENTY of other websites where you can discuss your 'deep, personal relationships with THE CREATOR'.

Exactly how would you feel if any of the MANY other religions offer you THEIR blessings?

Mod hat on!

Nor more discussion or debate by anyone on the matter of personal beliefs. If not associated with the Topic "Basic Linux "Code" then do it via PM.

To be clear, if you wish to continue this 'beliefs' discussion in this manner then do it via Personal Mail.
This forum is not the place for discussions of this type!

Back on Topic!

Back on Topic!

First, I'm not the brightest crayola in the box. I have medical issues that affect my brain and memory.

I appreciate the answers I got about Linux written in "C" or
"C++" and other languages. I learned what I thought could be
accomplished, can't. I HATE WINDOW$ because it's suseptible
to security glitches which means my computer can be hacked by
some low-life scum who doesn't know me to ruin my data that
worked very hard to get.

# 2. IF is could have been worked out, it would make someone,
not me, very rich, as folks who use Windows, would certainly
buy it. It maybe even constructed to secure *Nix computers.

#3. In my inital post, I ended it, as I always do. I did
not discuss any of my 'religion', it was a general statement.

So, as not to offend anyone else, who might take offense
at my political leanings, heritage, color of skin, hair, eye
color, or the way my nose sits on my face, I'll leave this
FORUM and wish you good luck.
