Procras^H^H^H Gaining Experience in GIS and Mapping

I bought a new mobile phone. My old Siemens SK65 started to annoy me by being generally shaky and having a flickering display (as you might have noticed I am not that into Flickring anymore...)

So I got a Nokia, it has WLAN, can do VOIP, has lots of other stuff with fancy abbreviations. And it can talk to a GPS via bluetooth. So I bought a bluetooth GPS mouse. I tried the Nokia Sports Tracker which is quite cool but cannot do a lot. It can do tracking though.

I then found AFTrack, which can do everything, from tracking to moving map. If you use a bitmap map, you need to calibrate it, which really sucks doing with the mobile's keypad and it is really slow. So I tried to find a better way...

AFTrack can read OziExplorer map files. OziExplorer can read GeoTIFF with a plugin (via Import Map->Import single DRG Map). So taking a scanned map, reading it in GRASS, marking coordinates in GRASS, saving as GeoTIFF, transfering to my Laptop (Windows...) to read it in OziExplorer and save as map-file. Then editing the map file by hand to convert from UTM to Latitude/Longitude using a web-based converter. Then saving it on the microSD card of my mobile, importing it in AFTrack and voilá, now I know where I am and find my way around Erlangen. Not that I didn't before...

(If you ask now why I needed GRASS, and did not use OziExplorer from start: I hoped not to have to use OziExlorer. And knowing a bit what a GIS does is also fine. And it can do a lot of warping around the map to get rid of distortions...)

Next Step: get the maps of the Virgen-Valley onto my mobile, so that I can get lost in the alps next week.

Competent Publishers

In Ferbruary I went to a conference in Vienna, where I presented a poster. The proceedings I wrote got accepted and will be published in NIM A, a high reputation journal published by Elsevier. Today I got a mail where I had to sign a copyright transferal. The copyright on the article, all included figures etc. has to be given to Elsevier. They can now do whatever they please with it. This is just the normal procedure how science publishing works: scientists (and people like me) write articles, where they do not get any money. The articles are then peer reviewed by other scientist, who also don't get any money. Then the article gets published, the original writer looses all copyright and the publisher sells the journal for some thousand Euro per edition. So far I did not really worry more than normal...

They did however address me as Dr., which is still wrong (and will be for some time...). So I sent them a mail:

Dear Sirs,

my contact details are not completely correct, I am not yet a Dr.
Can you please remove the title?


Tonight I got an aswer:

Dear Dr....


Should I trust publishers who cannot read mails?

No Comment.

Slight Redesign

As you may have noticed I changed the colours and the fonts of this blog. For best viewing experience you should have one of the fonts "Day Roman" or "Linux Libertine" installed (both free).

I also added a link to a portuguese science blog, which looks nice: De Rerum Natura

Digitising Slides

I am trying to digitise slides with this setup. For Sample images and more info follow the link at the picture above...

Smoke

Taking pictures of smoke is harder than I thought. You need to be faster than 1/60s, you need to focus fast and you need good smoke. And a CF card that works would also be nice... I lost about 50 pictures due to a crappy card.

Discalculy

Just saw an ad on TV:

Phone Flatrate: 0,--
DSL Flatrate: 0,--
No Base Fee: 0,--
Various other stuff: 0.--
-----------------------------
Sum: 29,-- Euro

Is it just me or do you also find this summation strange?

Two of my Hamburg pictures on flickr made it to a tourist guide on the web: one, two

Thesis

It seems that everything I was directly involved failed. While writing up it seems that all data that I took was useless, all tests I conducted showed that the detector is not understood and that the tests were useless. At least it will improve my english when I try to make it sound that everthing was great.

Else: this weekend my car wouldn't start (empty battery), my mobile broke (wrong pin entered three times while it was supposed to sit in my pocket being switched off), I met a lot of advanced-level-geeks and had a lot of good wheat beer. The beer was definitely the high point the last couple of days...

Weekend

A loaded weekend: saturday samba festival in coburg, sunday up at 4am to follow friends in a balloon to pick them up after landing, then back again to the samba festival. I took something about 700 photos this weekend. Now I have to wade through them all to pick the good ones and delete the bad ones...

But for some strange reason I am close to motivated to work. I should do weekends like this more often.

WTF?

Instead of ranting about our minister of interior going completely nuts (wanting targetet killings etc.) I'll blog about a city in Oregon who discovered that their traffic pilars look like penises:



I think they are right in banning these things. There is an awful lot of stuff which looks like penises and should be banned. Examples? Here they come:





Need to say more?

Moving slowly to the 21st century...

Today a lot of laws got passed by the Bundestag. Inbetween them is §202 E-StGB, which makes software illegal which has the purpose of attacking other computers. This includes nmap, ping and other usefull network tools, because they can be used to figure out weak points in your IT. It also includes all the tools any decent IT security person would use to check the systems he is responsible for.

Also passed got the second bucket of the Urheberrechtsnovelle, basically the copy-right law. From now on you can only access electronic publications from your university's library on special computers. The electronic subito is no longer allowed. To access research result's which were funded by tax money, published with tax money paid to the publisher, peer reviewed by tax money paid scientists (who don't get anything for this review), you now need to spend even more tax money to access. Elsevier and others will get rich, science will go boink.

Hurray to our well informed and competent politicians. [Note to those who can't understand German: it's politicians saying: "Internet, yeah, I think I have heard of it..."]

Computer

The next time some hardware fails I'll get a Mac. I just bought a new motherboard for my old PC and it took only some 5 hours to get things working again. Now I still don't have graphics via the DVI port, only some not very sharp output on the analogue port. But at least it works and I hope it won't crash that often as the old one did. As for the barebone which I had and where the porwer supply died: you cannot get that power supply anymore. This barebone is less than two years old... Hurray for short product cycles.

[Edit] Finally got the DVI working. It seems that envy is pretty useful if you have an nVidia or ATI card and want to use it with Linux. Also the nVidea settings program is quite OK (you have to run it as root though and the user interface is not really intuitive). So I have now a working graphics output on my DVI port, with 3d acceleration (including wobbly windows and desktops on a cube)

How to print an a5 booklet

You've got a file full of a5 pages and want to print it on an a4 printer so that you can fold it and it will be a booklet:


psbook -s<number_of_pages> file.ps file_sorted.ps


Number of pages is here the number of pages in a stack (normally the number of pages of the document plus a bit that it is dividable by 4). If you are binding a real book, it is the number of pages which will be folded and sewn together.


psnup -2 -pa4 -Pa5 file_sorted.ps printme.ps


-p is the page size of the output file, -P the page size of the input file.

Print with flipping on the short edge. This is tricky on the command line, but if you print from a viewer this should be easy...

As flickr seems to go the same way compuserve did go back in the early nineties (from a successfull community to a huge coorporate hell which ignores it's users and only focuses on shareholder value, from being great to being bancrupt because they overlooked what it really was they had...) I am now trying some alternatives. There is a good overview of alternatives (in german only though). I signed up at zooomr and 23hq, experiences will be posted here...


[EDIT] This is how flickr treats it's customers... (For those of you who do not speak german: this guy sent a mail saying that he is leaving. He got a response which basically tells him "We don't need you, just f*ck off")

[EDIT2] I also signed up at ipernity which looks quite nice

Politics

According to the political compass questionnaire I am belonging to the classical libertarian collectivism of anarcho-syndicalism. I am more left and liberitarian than Ghandi, Nelson Mandela and the Dalai Lama (Economic Left/Right: -5.50; Social Libertarian/Authoritarian: -6.82).

Seit gestern werden für deutsche Nutzer keine Bilder mehr angezeigt, die als 'moderate' oder 'restricted' markiert sind! Es gibt keine Moeglichkeit das umzustellen - das ist eine grobe Unverschämtheit und Frechheit von flickr!

In English:
If your Yahoo! ID is based in Singapore, Germany, Hong Kong or Korea you will only be able to view safe content based on your local Terms of Service so won’t be able to turn SafeSearch off.
In other words that means, that german users can not access photos on flickr that are not flaged "safe" ... only flowers and landscapes for the germans ...
We will not let this happen! Copy and upload this picture to your account - show flickr who we are!

Lade dieses Bild runter und poste es in deinem Account! Lass uns das Bild überall auf flickr verteilen und es in 'Interestingness' heben!! So geht es nicht!

Bikes and Computers

I got a new saddle for my bike today as the old one was falling apart. It has a ventilation system which keeps your rear end cool. Actually quite a nice feature...

I did a short cycle trip to check the saddle, to play with my GPS and to get some training. See picture for the trip, in total 19km.

The power supply of my computer died today, taking the fuse with it. So my living room (where also my fridge is located) was without electricity for some time... Fortunately the fridge is mostly empty. The computer was switched off while it happened, the computer has some fancy display which is always on, so the power supply was doing something. As it smelled quite badly, I think one of the capacities just exploded. This computer had about a year and a half... Hurray for reliable technology. So I am sitting now at my old desktop and wonder why I bought the new computer as it does not feel slower.

Web 2.0

Just returned from a field trip with fellow flickrites to the bergkirchweih... As we talked also a bit about geotagging, I was wondering, if you can include geo-tagged pictures in google earth. Well. You can... So, here is a google earth link of all my photos :-)
