427 vs 472

Tuesday, February 8th, 2011

My recent attempt to fix a problem with Regenradar not displaying the correct location failed ;) The problem occured due to a size change of the radar images provided by wetteronline. The displayed position is calculated from the longitude and latidue provided by the iphone GPS combined with the known longitude and latitude of two cities (Hamburg und Munich) and their position on the image (in pixels). When the size of the image changed, this pixel position of the cities needed to be udpated. While reading off the new positions from the image I introduced a typo, putting down 427px for Munich where it should have been 472px. So, while when being in Hamburg the position was correct, the further away the worse the position got.

tl;dr – new fixed version is on the way (1.3.6). I will test it today and will send it to Apple for review tomorrow.

[UPDATE] Update has been submitted to Apple, now we have to wait …

[UPDATE] Update is now available in the App Store. Please let me know about your experience (e.g. is the positioning now working as expected)

every 3 months …

.. there seems to be changes in the bahn website. At the moment the details view of ZugInfo is broken and I am looking into it. I keep you posted.

[Update] There we go, problem fixed (though I don’t quite understand why someone wanted to remove http from a hyperlink address). I will wait a little longer before submitting the fix, since you never know .. maybe there is more to come.

[Update] More changes, more updates. This time adressing an issue when quering a non-unique location resulting in an error. Technical detail: again a web address on the bahn website lost it’s http pre-fix. Will submit the fix later today (3/10/10). Sorry for the inconvenience.

oops .. they did it again

Today the DB website changed and caused some problems with the ZugInfo display of the connection type (thx to Markus for pointing that out). I am working on an update…..

[Update:] I got a working version of a quick fix on my laptop. A few more test and I will submit it to the App Store.

[Update:] A quick fix version has been submitted to the App Store. If anyone knows how to speed up the Apple review process, please contact me. Thank you for your patience.

[Update:] Thanks to the Apple review team the update is now available at the App Store (Oct. 3rd).

daylight saving

Tuesday, October 28th, 2008

I always liked the daylight saving time. This completely (scientific proven) useless ritual always filled me with joy. The gambling with time, a quantity that can be changed by men, gain and loose, give and take, early wake-ups late-sleepins, and all for our own good, or at least natures.

So … daylight saving time sort-of-broke my RegenRadar app. It still works, but has hickups. The update is on the way (under review at the Apple HQ). No one got hurt, my ego maybe a bit.

And actually that is what I would expect from a weekend where men decide to change time. A little bit of chaos, like the one we expected for the millenium and which never happened (ok, I admit, millennium bug and my RegenRadar daylight saving time bug, not the best comparison).

Enough chit-chat: update is on its way and hope to see you soon.

good night and goodbye.

I have another 4h of work ahead waiting for me in a control room.

aiks! bug.

So you think you thought of everything: you checked the code, ran the app, double checked the code. You designed crazy test scenarios, pressed all buttons at once, and let the app ran for two days straight.

But where there is the sea there is an island.

ZugInfo 1.0.1 – the bugfix release.

No more infinity loops for “Konstanz”, “Cuxhaven”, “Elsfleth”. No more confused results for “Nürnberg” , “München” and “Günzburg”. For the first time it does know Umlaute (and does not only pretend it does). And in addition: with memory management.

Believe it or not: the 1.0 version does not have a working memory management. Of course I read about it and tried my best. But in the end I though some code from Apple would take care of it (namely some UINavigationController method), but it obviously didn’t (try to run it for ~20 searches and see for yourself). Everything you have to do yourself.

PS: I spawned a new project. It has something to do with the recent weather developments in Germany (like, uh, rain or something).
