I recently switched to a dark Gnome2 theme and realized, that firefox did use that colors too. But also firefox used these colors for the input forms on some websites. I found out how to partially fix this.

These strangely colored input field will be there when the website did not define any other colors to these elements.

There is a way to make these fields white again with the following instructions:

You need to create or append this file

with this content:

Download: userContent.css

It will give Firefox default values to use when a website does not set any colors for form inputs.
You need to restart Firefox to activate these settings.

You can test it here: Test-Forms

But the check-box input fields are still black. I think because Firefox does not render these Elements on its own, but let GTK do it. I could not find any method to reset these to normal again.

I created my own grafic about the triangle:

Let me explain why i choose these 3 factors:

Time

In any project, time mostly means that there is a deadline that should not be broken. If there is not much time at all or it gets reduced, it means there is less effort for the result which leads to less quality.

Cost

The customers who pays for your work, always wants to pay less as possible. But reducing cost means reducing manpower and ignoring better solutions. That also leads to less quality.

Scope

Reducing scope of the project. Doing less as you should or doing it in a sloppy way. As long as the customer does not notice, there is no real problem, till the moment when something is broken or needs refactoring.

Quality

Quality = Time * Scope * Cost. If you reduce any of the 3 factors, quality will decrease. In the end, quality is what the customers pay for. Nobody would by a car that will break down in the first turn.

"Pick 2"

Some explanations about this concept say, you can always just pick 2 of the factors to concentrate. I do not agree with that because it makes the whole problem way too easy. There are ways to solve this so the best possible product is created. I count agile development like scrum and kanban to this.

Locate profile folder

First, we need to shut down Thunderbird and locate the Profile folder. On Ubuntu this is in you home directory in "~/.mozilla-thunderbird/". In your profile folder is another folder called "News". Therein are all the subscribed News-servers and topics. Now you need to open the .rc file. In my case is is: "news.fh-wedel.de.rc"

Open .rc file

The content should look similar to this:

The principle behind this file is simple. All the read messages are marked. For example ALL messages in "fhw.db" are read. But in fhw.talk the messages 23185, 23219, ... are unread.
And exactly here is the problem. Some of these messages are marked as unread, but you already read them, so some of these number are wrong.

Repair .rc file

Simple solution is, clear them all!
The content of the file with all messages marked as read should look like this:

Now save the file and reopen thunderbird and your messages should now be marked as read.

Lidl pay desk hack

This hack is a little bit older but might work also on other pay desk machines.
You can get the pay desk machine to crash if your receipt has a total of 0.00 Euro.
This can be done with a few refund bottles and some queap stuff like joghurt or bubblegum.
The result is a pay desk machine that does not work anymore and needs to be restarted by the chief.

Elevator hack

There is the rumor that you can "hack" a elevator.
This can be done by pressing the "close door" and the "floor" button you want to go.
Actual, this was intended to be used be engineers for testing purposes. Maybe it can become handy sometimes.
