Welcome to tec4u This page is called into life because i got bored with scouring the internet for answers on what i wanted to do, having to read blogs that have lots of so-called "experts" that do either or all of: Either way, the answers are few and far between.

So what can you find here?

Simple: just straight to the point pages with howto's on topics I either have an interest in, have been submitted or I ran in to during hobby and/or work.
I shared them on these pages in public so anybody can use them, hopefully they solve other people's problems or projects.
Yes, i know about the miriad of sites (like github, instructables etc. etc.) that do something like it, but i also don't want to be bothered by their cms, administration, constant emails about nothing, etc.

I in no way claim the solutions here are perfect or even the best ones (i am sure there are better ones), but these do work.

All pages are made in simple html files, no fuss, no nothing.
Maybe at some point a cms will be installed, but for the time being this way works and it saves constant maintenance for security issues.

If you have a nice solution to a problem and think it fits with the idea of this website: you are welcome to share them here.
If you do, just create a webpage for it (index.html, with or without css etc). It's nice if you use the layout here, but not mandatory.
Once done, zip it and mail it to tec4u - at - spambak -dot- nl


Obligatory disclaimer (yes... we unfortunatly live in that kindof world these days): i take absolutely NO responsibility in any way, shape or form for any data loss or damages you might inflict using the projects and/or solutions on these pages.
Nor am i liable (or will accept any responsibility) for damages to anything you use these projects/solutions in, or with (this applies to devices, vehicles, apparatus, clothing, cats, dogs, pigeons or anything else not mentioned).
