Hi everybody, recently I had some people, who asked me, what useful links I had for new learners of Oracle SQL, PL/SQL and Apex. That’s why I did the following little list: First of all, it’s useful to create an account with Oracle, if you don’t already have one (it’s free and you don’t need any Oracle Licenses for that):https://profile.oracle.com/myprofile/account/create-account.jspx – actually, nearly every page listed below demands that, but you always also have the possibility to create an account there as well. With an Oracle account you can download the Oracle XE database (that is basically a full database, with…

Hi everybody, ever wanted to know a quick way to see, what your IP-Address is and where the web thinks you are located based on the IP? Check out here: https://ipinfo.idstein-online.com. The page is still under construction, but already does what it should do. Have fun! Take care!

Hi everybody, Yesterday I received a strange E-Mail (Subject: Domain IDSTEIN-ONLINE.COM Suspension Notice) from my host provider, stating that my Domain has been suspended after several complaints about my page. Well, I have not heard anything about that yet, I wondered. Nevertheless, it seemed to come from my host provider Dreamhost and stated my website address. It also gave a link to a page, where the list of complaints could be downloaded. Well after checking the domain name of the link: It’s crap, bollocks! If you ever receive such an E-Mail (currently they seem to be sent for several host providers,…

It seems there is a problem with the chain of referrers with IE 11. If I try to connect with IE11 to http://chart.apis.google.com, it seems I am referred to https://chart.apis.google.com – the check of the security certificate here fails and exceptions to the rule are not allowed. If I try to connect with Firefox to http://chart.apis.google.com, I seem to get referred to https://developers.google.com/chart/?csw=1 direcly, which works. If I try to connect to the https://chart.apis.google.com, I also see a fail of the check of the security certificate and the rule permits to add the page to the exception pages. It seems…

Hello everybody, Another post about upgrading to Windows 10, this time on an Oracle VirtualBox. Well, after several failed attempts, the following setting solved it for me: In the settings of the virtual machine, click the “Enable PAE/NX” to activated (find the detailled description with a screenshot here: http://www.eightforums.com/installation-setup/4032-your-pc-needs-repaired-error-0xc0000260-2.html?s=c8602c42ab3c48baaa23fbbb324e5557. Please be aware though, that for this to work in the BIOS of your host system the virtualisation support has to be activated (e.g. AMD-V, VT-x). After that, the installation was snooth and made not any problems whatsoever! Good luck!

Hello everybody, As probably a lot of people lately, I tried to get some of my devices to upgrade from Windows 7 or 8 to Windows 10. However, it was not easy, since I was not one of the first in the queue for MS obviously. Well, anyway, there are some descriptions out there how to force your Windows to download the update (if you are not good with Google, take a look here for example: http://www.itechtics.com/download-internet-explorer-all-versions/). Anyway, if you are looking for the error code 80240020, that my Asus convertible displayed after I did this, most pages will just…

Hi, As long as I can remember, Nokia mobile phones were the easiest to use and the ones where the menu structure was the most intuitive. It is very sad, that Nokia was sold to Microsoft, and now, even more sad, Microsoft has decided to not develop new phones (http://www.theguardian.com/technology/2015/jul/08/windows-phone-microsoft-nokia-layoff-smartphones). Well, the good news is that Nokia also is allowed to sell their own phones again soon. So I hope, that they will and will do it right (a Nokia-Android, maybe?). Please, take Apple as an idol company, that also was nearly bancrupt once and is now the most valuable…

Hi all, Recently, I tried to export a jpg and a bmp-file from a java-application and wanted to set the dpi-value to 300. Oh boy, that was not easy :-). That’s why I have the 2 links that finally helped me solve the problem collected here: For jpg-files, please read the following (also read the chosen answer): http://stackoverflow.com/questions/233504/write-dpi-metadata-to-a-jpeg-image-in-java For bmp-files, the following method was very helpful (look at the answer from inflamer): http://www.java-forum.org/awt-swing-javafx-and-swt/29574-bmp-imageio-schreiben.html Funny, that since 2006, obviously there is still no easier option to write the DPI-value of a bitmap export (at least none that I found).

Last weekend I played ‘The Sims 4’ for the first time. My wife and I had gone for a ‘Limited Edition’ and as it seems, it is a rather good new version of the game. Of course, for people who played ‘The Sims’ since their first appearance, there are quite a few missing things and the re-appearance of loading screens when leaving the house is a little bit of a disturbance. We missed some kind of restaurant or bistro on the common grounds, but on the whole, the playing experience is still rather rewarding. The positive sides are definitely the…
