ControlTheoryPro: Welcome to the site devoted to Control Systems
Unfortunately the SPAMers got around the reCAPTCHA I implemented. So I've been forced to shut the new accounts on this site. That way the site can continue (hopefully SPAM free) now without requiring me to devote gobs and gobs of time to deleting these irritating, none Controls related, posts.
Unfortunately the SPAMMERs got around my no new accounts...
I believe I've figured out how the SPAMMERs keep creating new accounts on my wiki. I don't have the time right now to work the issue but it appears to be related to a particular extension I use on the front page. Unfortunately, removing it will make the front page pretty bland. I'm also in the process of attempting to upgrade my site to MediaWiki 1.16. (This 1.11 and 1.18 is the latest but I haven't had much luck getting the site upgraded to 1.18. I've got a version - kind of working - with 1.16 so keep your fingers crossed.)
Even though I've shut down the registration page the SPAMMERs have gotten around the lack of a registration page. I continue to work out how this is happening. At this point I am hoping that upgrading the site the latest version of mediawiki will solve the problem (probably with some version of reCAPTCHA on the form).
I apologize for the continued interruption of registration to those looking to make a meaningful contribution to the site.
A special note to all SPAMMERs (who aren't using automation to ruin the site) I have a cron job that runs every 5 minutes to remove your profile, your profile page, and all evidence of your existence on my site. I know how to manipulate the DB even if I don't know exactly how to manipulate the mediwiki code (yet).
Wish me luck...
The equations went down again but they are back up...
I also need to apologize for the equations going down yet again. As some of you may know from trading emails with me the equations are rendered using MathTex which displays much nicer equations than the alternative I had back in 2008 when I started this wiki. However, MathTex can require a lot of processing power.
My server is capable of it but does the rendering rather slowly so I have been using external servers which were faster and had public MathTex renders they didn't mind sharing. Unfortunately, this last server like several previously decided to shut down its public access to MathTex - probably for the fact that the server can get overwhelmed rather easily.
The equations are showing again because they are being rendered by my server. I have always used a cache so as to not abuse the rendering servers and this should help with the speed issue I mentioned above. However, I still expect the rendering to be a little slower than it used to be but at least the equations are being rendered.
Thanks for your patience.
On a happier note...
Thanks to those new users which recently corrected some of my typos. I appreciate your efforts in making the site more accurate and my own typos are very hard to find after I've been staring at the material for hours on end...
Keep up the good work and thanks for following the basics of the Style Guide.
Just haven't had the time
I've been intending to create an SEO guide to go along with that Style Guide to provide some tips on how to structure your writing style so that Google picks up your contributions better. Honestly, it would make me eccstatic if one of the contributors to this site got a job because someone saw those contributions. That is far more likely if Google picks up your pages and ranks them well.
Absolutely anything you write (as long as it is controls/MATLAB/math/engineering related) is welcome. However, here are a couple of tips for making Google like your pages much more:
- Write naturally so readers like the article first and foremost but be explicit. For example, good writing style would likely dictate that the main topic be referred to at least once in most paragraphs. However, we tend to use short hand and instead of writing a PID controller has the benefits of ... we write The controller has the ... Google will like your page a lot better if you replace the lazy short hand with more a explicit writing style and I've found the articles are far easier to follow if you are reading them for the first time.
- Instead on naming the first section Introduction name it Introduction to X where X is the full name (or nearly full name) of the article.
- As you are creating sections, repeat some form of the topic in those headings. For example, if page is on PID control then the first section is Introduction to PID Control, the next section could be Standard Form of the PID Controller, the following section being titled Example: PID Control of a Second Order System.
