Monday, January 31. 2011VOR-/ÖBB-Fahrpläne mit Android abrufen, III![]() Nach einer ersten Auflistung einiger Möglichkeiten im April 2010 und einem Follow-Up im Juni mache ich hier nun weitere aktuelle Ergänzungen und erstelle einen Überblick, zumal immer wieder Leute zu dem Thema hier „aufschlagen“ (z.B. in den Kommentaren oder per einschlägiger Websuche). Die unten angeführte Liste ist nach meiner persönlichen Präferenz gereiht, gemäß folgender Anforderungen:
Hier nun meine Lösungen:
Zum Schluss sei noch auf eine Speziallösung hingewiesen: Offizielle RSS-Feeds über Betriebsstörungen. Ja, diese Feeds gibt es, und sie sind gut versteckt, aber via ÖBB-Streckeninformation zu finden. Sie würden sich gut z.B. in einem RSS-Widget machen. [Update 01.02.] Ein Twitter-User hat mich darauf aufmerksam gemacht, dass es offenbar im 2. Quartal eine Android-App von den ÖBB geben soll. Dies geht aus einem Kommentar auf der Facebook-Seite der ÖBB vom 5. Jänner hervor. Thursday, January 20. 2011Aftermath in the truest sense, II![]() One year ago I wrote about that I was authoring a chapter for a book about mathematical imaging together with O. Christensen and H. Feichtinger. Some months ago our contribution was accepted as Chapter 29 (“Gabor Analysis for Imaging”) of Springer’s “Handbook of Mathematical Methods in Imaging” (ISBN 978-0-387-92920-0). The book is available for online access since last week for ~€600. As it has got 1607 pages, it will take me some time to read through it. As mentioned previously, our content mainly resembles the structure of my Master’s thesis from 2007, but with more mathematical rigor thanks to the two mentioned authors. Originally I wanted to recreate the pictures I had shown in my thesis, but decided to just reuse them.

Thursday, December 16. 2010MTA configuration FAILFrom: SPAM@somewhere.at WTF? Monday, November 1. 2010How I'd like to use Twitter![]() (The following is a kind of current-state analysis, maybe leading to my long intended anti-WWW rant. Honestly, I think Twitter is a broken technology. 140 characters are way too few to provide useful context. And as URLs eat from this character pool, the urge for link shorteners simply leaves this service behind broken, IMHO. Just look at this plot of the distribution of tweet lenghts: Well, some misuse Twitter as a chat, although IRC would be the technology of choice for that. I mainly use it as a news stream. In fact, Twitter changed their orientation from individual “Took a dump, ate a banana” status updates to personalized news. Although RSS or Atom are dedicated technology for collecting headlines and articles (and keeping their read/unread state), Twitter provides a unified time flow (that passes by, no matter if you read it or not). And while RSS/Atom is a kind of pull technology (i.e. you have to look at different feeds and articles for yourself), Twitter is a push variant where all elements meld into a single data stream. The problem is, in engineering terms, there’s so much noise in the data; there’s so much irrelevancy occurring in the timeline, at least in mine. I followed more and more people, like “Hey, this guy developped that app, and there’s a link to his Twitter”, or I chose to follow various companies when I noticed they had an account at Twitter. But more and more often I asked myself where a certain guy/gal I followed actually came from. I’m wasting too much time at Twitter. Meanwhile, I’m following more than 250 people. (Yeah, I think those who follow >300 are simply nuts. How the hell do they handle their timeline? How can they claim Twitter is not a distraction?) Me wants:
Of course, a lot of this already sounds like RSS. But there are tweets that are status updates per se and don’t contain URLs. It appears to me that Twitter and RSS (and maybe the whole social *BUZZWORD ALERT* media) are becoming “the HTTP of a new WWW”: It’s up to new and upcoming user interfaces to aggregate, weight, filter, sort and manage content coming from various data streams; new user interfaces for new devices, but also for the “old scholars”. I noticed recently that things are becoming better for me when using different Twitter—or rather, aggregator—clients, like TweetDeck or My6Sense. It’s becoming important for me to not just scream or hear screams, but to consume and provide relevant information. Thursday, October 21. 2010Why I rooted my phone![]() This is just a note for myself what hacks I applied to my phone to make it more usable to me. This is to reproduce these settings once I flash the full Android 2.2 “FroYo” image onto my Motorola Milestone:
* Achieved by TimeTurn’s OpenRecovery for Milestone And while we’re at it: Of course the Android system has got some flaws, but I think the situation’s similar to desktop environments: The on-board software is able to provide some basic things, but it’s up to third party developers to provide apps with full functionality, especially when I think of features regarding contacts (e.g. edit groups and birthdays, share via Bluetooth or SMS), calendar (e.g. search) or e-mail (e.g. search). Further apps I have installed are on this always almost complete and up-to-date list—HTH: Continue reading "Why I rooted my phone" Monday, October 4. 2010XING SPAM FAILThursday, September 9. 2010Wo das Netz nicht gar so dünn ist, II![]() Ich habe nun wieder meinen von früher lieb gewonnenen Downstream von 16 Mbit/s und Upstream von 1 Mbit/s – und das außerhalb des Ballungsraums. Eher durch Zufall bin ich draufgekommen, dass es sowas wie VDSL gibt, noch dazu in Österreich, und noch dazu ausschließlich von der Telekom, für die ich mich letztlich entschieden hatte. Fast zwei Jahre lang fuhr ich ja auf 6 Mbit/512 kbit, was eigentlich für mich ganz OK war, abgesehen vom schneckenden Upstream bei Foto-Uploads oder Mail-Attachments. Nun habe ich mit deren GigaSpeed 16 also wieder meine „1-fache“ Geschwindigkeit, ohne auf Alternativtechnologien wie TV-Kabel oder Funk ausgewichen zu sein. Bei SpeedTest.net konnte ich 10–11 Mbit (max. 12,5 Mbit) Downstream messen, während der Upstream recht gut mit bis zu 0,96 Mbit ausgereizt wird; beides also praktisch eine Verdoppelung. Es wäre sogar das GigaSpeed 30 mit 30 Mbit/3 Mbit möglich gewesen, wäre aber zu viel des Guten für meine Verhältnisse. Warten wir erstmal ein paar Jahre ab, bis des Sohnes Ansprüche größer werden. Wednesday, September 1. 2010A peek on current DSLR tech, II![]() Apparently, it’s time for my yearly follow-up on Canon’s releases. Canon announced the EOS 60D. It’s interesting that their prosumer “x0D” line now got downgraded in a certain sense: This DSLR became more similar to a cheaper bridge camera, with a vari-angle LCD, less weight, plastic housing, fewer fps and SD cards instead of CF. This is probably a measure for increasing the difference to their EOS 7D, which should attract the more dedicated amateur. However, there won’t be a 7D or 5D Mk II in my hands at all. My 40D is just working fine for me; unfortunately, I hardly found time to hold dedicated photography sessions apart from the obvious ones with my child. There’s still a lot of potential with and within my camera, although the maximum (unboosted) ISO of only 1600 is rather limiting sometimes, given that one could have ISO 6400 with current models. And the limited number of occasions I mentioned is also a reason why there was no “lens p0rn” in my blog recently. Although I had predicted the purchase of a tele lens for fall 2008 and then for the end of 2009, I didn’t buy one, as I rarely missed such a tool. However, there seems to be the ultimate candidate for me to finally put one into my bag at the end of 2010: Canon’s newly introduced EF 70-300mm f/4-5.6 L(!) IS USM. It’s rather compact and doesn’t possess the disputed design of their aging 100-400mm. It appears to me as a 70-200mm f/4 “with the 1.4× extender included” in some sense. It’ll be available by October for €1,400. Let’s see if that’ll be my Xmas present for me, or if I rather go for a completely different gadget (namely an Android tablet).
