Wie ich im Internet im Zuge meiner tagelangen Recherche feststellen musste, haben sehr viele das gleiche Problem wie ich es nun hatte. Nach wenigen Jahren sitzen Sie vor einem eigentlich noch hervorragenden mobilen Rechner (in meinem Falle ein Dell Latitude D830, 4 Jahre alt) und können ihn nicht mehr nutzen, da die Grafikkarte, welche onboard mit dem Mainboard verbundelt ist, den Geist aufgegeben hat. Zunächst seht ihr Streifen, Pixel und komische Zeichen im Bild. Dann wird der Bildschirm komplett schwarz.

Following scenario:

I have a database table, where information about an user is stored in several rows.

Source code

user_id, date, information_about_user_on_date
1, 2011-11-01, information_1
1, 2011-11-02, information_2
1, 2011-11-03, information_3

This information I want to show in one single line without getting this information row by row. SQL has the nice functionality „GROUP BY“ but by using this normally I’m only getting one information.Read More

Jeder, der schon einemal eine Webseite erstellt hat, kennt folgendes Problem:

Du entwickelts dein Webprojekt lokal auf deiner Maschine. Alles sieht gut aus, genau, wie du es dir vorgestellt hast. Dann lädst du diese Seite auf den Webserver und testest, ob es immer noch so aussieht, wie es soll. Ja, alles ist wunderbar!

Dann ruft dich ein Freund an und fragt: Was hast du denn da gemacht? Sieht ja furchtbar aus! Die Texte sehen ganz furchtbar aus und die Abschnitte sprengen dein Seitendesign!

Wie kann das Sein?! Der Grund ist, dass auf deinem System die Schiftarten, die du verwendet hast, existieren uns somit von Browser geladen werden können. Auf anderen Systemen existieren diese vielleicht nicht. Nur Verdana, Arial und eine handvoll anderer Schriftarten sind Standard auf jedem System und somit verfügbar. Du möchtest aber spezielle Schiftarten verwenden, die besser in dein entwickeltes Design passen.Read More

Everybody knows that problem:

You develop your Website on your local system. Everything looks nice and good. Then you upload your code on your Webserver, test, if everything looks like it should and you are happy.

Then a friend calls you and you got to here: What have you done? It looks horrible! The Texts are looking bad and the Paragraphs are breaking the page design!

How can that be? The Reason is, that on your System the Fonts, you are using are existing and can be loaded by the browser. On other Systems maybe that fonts are not existing. Only Arial and Verdana and a hend full of other fonts are installed on every system. But you want to use special fonts for your website that are fitting better in your design.

Since my last update of my WordPress blog it was horrible slow. My mobile phone was not able to load the blog anymore, my computer needs something arround one or one and a half minutes to load the next page, on the blog and in the admin dashboard too. I asked myself why.Read More

If you are a developer of websites or -software, you know this problem:

While developing of websites is really a tie to make them compatible for all browsers. Especially because it is not possible to habe all needed browsers on your system. But here are a few possibilities how you can test most of the browsers you want to test.Read More

Following Problem was happened to me:

I had a HTML form to send text data to the webserver. Because it was only text data, I used the enctype „text“.

<form name="formname" enctype="text" method="post" action="saveData.php">

This works in every browser like IE, Firefox and Safari. But I never tested it in the Google Chrome browser.

The form had some mandatory fields. If not all of these fields are filled, the not filled fields are colored red and the hint is shown, that all mandatory fields must be filled. Then a user called me and told me, that he is not able to register. He filled all fields and pressed the register button. Then the form was shown again, all fields were empty and all mandatory fields were colored red.Read More
