• You've reached the web space of Ulf Dittmer. This site looks a bit different than other places, as it's running on wiki software, and I can't be bothered to make it look visually nice. Hopefully you've come for the content. If you're looking for something in particular, use the search box.

  • RecentMovies has notes about movies I've seen, going all the way back to 2004.

  • BrewpubsBerlin keeps track of which brewpubs I've visited in Berlin and elsewhere in Germany. It includes my impressions, web links, addresses and a Google map showing them all. PubsBerlin lists most of the English and Irish pubs in the city, although I haven't visited most of them.

  • Some stuff I've written, mostly tech articles and book reviews, can be found in MyWriting

  • If you've been here before, check out RecentChanges to see what's new.

  • If you're interested in getting in touch, I'm on Email, XING and LinkedIn. If you send a contact request, make sure to state why you want to connect.

What's new?

  • Added PdfboxAnnotation, PdfboxTable and PdfboxReplace - example codes that show how to alter the appearance of text in a PDF (highlighting, underlining and striking out), how to add tables to a PDF, and how to search and replace text in a PDF, all with the help of the Apache PDFBox library

  • A writeup of our Hurtigruten trip along the Norwegian coast in German and English with lots of pictures

My software projects

If any of my software has been helpful to you or your company, and you feel like expressing your gratitude beyond saying Thank you (which is also appreciated), please note that I have an Amazon Wish List containing several inexpensive items, or you can contribute directly via PayPal.

  • My Android app Ping & Net for TCP/IP network diagnostics is available in the Google Play Store for free.

  • I'm committer to JForum2, open source web-based forum software written in Java which was updated recently for use on mobile devices, and cewolf, a JSP tag library for embedding charts in Java web apps (although that one is dormant now).

  • ProfileViewer helps make sense of Java profiling information and GNU gprof output. It's sort of outdated now, although still functional.

  • PrologJava: Thinking about combining Prolog and Java? Here's a BSF engine for JLog (a Prolog-in-Java system) that I created some time ago

  • CpuSimulator6502: j6502 is a 6502 CPU simulator written in Java. There's also an assembler that generates object code for it. For those too young to remember, the 6502 powered computers such as the Apple //, the Atari 400/800, and various Commodore models like the PET-2001 and the C-64.

  • CodeSnippets contains various small pieces of code -mostly in Java- that may be of wider interest. Also a few fun or marginally useful applets that I resurrected from the dustbin.

  • JavascriptUtilities has some web development and JavaScript utilities: a regexp tester, a keycode tester, a browser plugin lister, and a text flipper for fun
