Hi. I am Cor,
Writer, maker of tools..

I write. I make tools.
Maybe you've heard of some of them, maybe..

checksum checksum icon/logo, in super-large groovy 256 pixel size PNG!
The world's fastest hashing app, favoured by governments and hackers alike, and maybe you. It's peace of mind, with a click.
or
perhaps..
whatsitsname ffe icon/logo, in super-large multicolored 256 pixel size PNG!
With unpatented MATOF™ technology. And full source code, so you can see.
or maybe one of the others..
LoopDropZ logo - a simple circle, composed of an arrow turning in on itself, a loop. The colours are my yellow-orange gradient, the arrow growing darker as it turns, until realizing itself into a loop, oozes back to yellow, to begin again. Rather groovy image of a clipboard, in gold. 128 pixel size PNG image of KDE Mover-Sizer icon/logo; the famous KDE Krystal icon, the 'K' masked in with a windows flag, set at the perfect angle. Rather groovy image of a big X, in orange-yellow gradient, of course. The word MAX_PATH is emblazoned upon its arms and legs 128 pixel PNG image of Color Pickin Chooser icon/logo in red-yellow gradient. Nah, just kidding - it is four simple, slightly rounded squares in pastel shades, clockwise from top-left; green, pink, orange, blue. ...

Music..

I have always made music and now have literally thousands of songs scattered around the place. Few have had a proper "release". I have started to do something about that..

Bandcamp icon.

Images,
like these free widescreen wallpapers are..

Thumbnail of some unique desktop wallpaper: 'Tulips at Dawn' - A classic flower shot with beautiful complimentary sky colour, and no lame fill-flash. Thumbnail image of some free, unique, corz.org desktop wallpaper. In this case, 'Coffee Swirlz' Thumbnail image of some free, unique, corz.org desktop wallpaper. In this case, 'Sunrise Over Brig O Don'
Thumbnail image of some free, unique, corz.org desktop wallpaper. In this case, 'CCD_Meltdown_02' - a direct capture from a CCD breaking down.. Thumbnail image of some free, unique, corz.org desktop wallpaper. In this case, 'Mushroom-On-Tree (Alder Bracket Fungi), number 1' in high contrast! Thumbnail image of some free, unique, corz.org desktop wallpaper. In this case, 'Dry Stane Dyke'

I can get Scanoramic when I have to..

But usually end up making more tools..

..web server fun

Maybe, like millions before you came here to leech check out some of my world-famous .htaccess tips and tricks. Hey, if you make web sites, why not check out some juicy web techniques or grab some groovy Web Site Spare Parts™ or while you're at it!

Like the world's fastest live php search engine..

corzoogle logo - looks a bit like the Google logo, but with more colors, and 'corz' instead of the 'G', of corz.

Or a back-end download machine that can not only count and log your web downloads, but embed its download menus right inside your site's pages, like this (simple example)..


Or a php login system that closes a common (commonly ignored, that is) browser security hole? That would be pajamas.

Or perhaps a dynamic 404 page capable of not only automatically seeking out your site's missing pages, but jumping users directly to files you just happened to move, even fixing your broken links (even broken image links) on-the-fly.. And while it's at it, handles all your error documents, 403, 500, 401, whatever you need.. Meet Active Error Pages.

Or what about a Hot-Link script capable not just of defeating nasty bandwidth thefts, but of transforming them into free promotions for your site! Auto-HotLink is free, too.

Or what about a way to protect your site from bandwidth-sucking site hammers, bad bots, script-kiddies, h4x0rs, referer spammers and more? That would be the often-copied, never equalled, one-and-only.. Anti-Hammer. Note: Anti-Hammer Pro now available!

..just some of the highlights.

a corz.org hot-linked image, as seen from outside. The text folk see on THAT site, is up to YOU! This one reads, We love corz.org!. Well, dontcha!

Or maybe you want to setup a server, or do some P2P file sharing, and got tricked into thinking I had the most accessible Static IP tutorial on the web. Sucker! It just looks that way because the rest are so poor (that's still a great way to get on top in many fields of endeavour). There are quite a few other tutorials kicking around here, more get added all the time, as time allows.

The networking stuff has been thrown here. I aim to expand this area, share some of my work with OpenWrt, amongst other things. As time allows.

Still here?

Maybe you were looking for something else. Do feel free to rake around, there is a lot more inside, and a lot of it fairly well hidden, needs locating. That search function is handy for that, I find (at the foot).

You can find all sorts here at the org; software for Windows, Linux and Mac, as well as shell scripts for those three and others; php, C, C++, Javascript, AutoIt, AutoHotKey, CSS, BASH and DOS code, as well as packages of all sorts, even IPCop binaries. And poems, of course, and songs, photo galleries, blogs, essays, designs, mandalas, T-Shirts and other similar juicy merchandise, icons, clip-art, oodles of server tools and security resources, tutorials, audio loops, browser add-ons, automation scripts, why, there's even an AI kicking around somewhere, for fun. And much more..

I'm here full-time, making your life easier!

So while you are passing through, reaping the benefits, perhaps you might consider helping out with my family's next meal (that's four mouths now!), pair of shoes, that sort of thing..

Every penny is gratefully received. Though donations of under a quid get laughed at. I mean seriously, five pence?

Either way, people do say lots and lots of nice things..

Note: refresh the page for even more!

Welcome to corz.org!

Since switching hosts (I hope you are alright, Ed! Wherever you are …) quite a few things seems to be wonky.

Juggling two energetic boys (of very different ages) on Coronavirus lockdown, I'm unlikely to have them all fixed any time soon. Mail me! to prioritise!
