Hi all,
Well, "free" in this case is actually $227, but anyway it means that those of us who can't wait until Maemo5-equipped device is released can have something right now.
I've been following the news about buy.com prices, but it was not available for non-US people. Amazon fixed this injustice :)
Hi all,
Yesterday I learned a feature which I'm sure should be described in every C book. To be honest, 'man snprintf' describes it as a part of C99, but I've never read the article completely.
Often when you construct a string using 'snprintf()' you need to allocate enough space for the buffer. But it's not possible to know how much you may need, so usually we just do something like this:
char buf1[1024];
/* or */
char *buf2 = malloc(1024);
int len = 1 + snprintf(NULL, 0, "%s, %s\n", "Hello", "world") ;
char *buf = malloc(len);
snprintf(buf, len, "%s, %s\n", "Hello", "world");
Hi all!
Great news - Fring is now available for maemo platform. Fring is an application that combines a number of protocols such as Skype, ICQ, GTalk into one handy program. You may find it following this link. Here is the screenshot I took from Fring's russian blog. It should work for both chinook and diablo. The announce says about N810, but I'll give it a try tomorrow on my N800.
After patching maemo-mapper application to support Yandex maps Max Lapan, their employee suggested his script that worked as CGI script and converted mmapper's links to yandex's ones. That was really awesome idea as there is no need to update application and contacting its developer all the time, we can just run script on 127.0.0.1 and pass parameters like city ID and x/y/z to it. Note, that Yandex is not that simple as other map vendors - there is no world map with all cities on it. Each city has its own ID and its own set of dimensions - Xs,Ys of upper left and bottom right corners of each rectangle. So I think we(interested people from Russia and Ukraine) will have to create list of supported cities with verified set of dimensions and IDs. So each city will have it's own repository in maemo mapper(see screenshot below).
I'm open to discussions about this implementation as GPS and other features are unlikely to work seamlessly and road traffic service is currenly unsupported. It's not possible to add it without patching maemo-mapper itself. But for me and probably for other people map is the most important feature.
How to setup a new repository:
URL for the map is "http://127.0.0.1:8000/?map=NUMBER&layer=1&x=%d&y=%d&z=%d"
where NUMBER is a special code for each city(Kiev=1600, Moscow=2000, St.Petersburg=500, and so on)
Download Zoom Steps: 1
View Zoom steps: 1
Downloadable zooms: min: 6, max: 14
So then we may download map for offline use as usual. I use 11,9,7 zoom levels + 6 for city center. It's about 50mb on a flash. It's better to move data file from "/home/user/MyDocs/.documents/Maps" to somewhere at /media/mmc* and create a symlink instead.
Python script can be downloaded following this link. To run simply put it somewhere in home dir and:
$ python yandexmap.py
Roadmap for the script:
Guys, I need map!
After googling for Maemo mapper format I found only this very useful link at internettablettalk with the list of supported servers. But unfortunately it's not that simple for us, Ukrainians. Google Maps does not have streets map even of our capital, Kiev. Russian yandex's map service is still the best, but its format is not that simple as google's:
Yandex Maps:
http://maps.yandex.ua/map.xml?mapID=1600&mapX=%d&mapY=%d&scale=%d
http://maps.yandex.ua/map.xml?mapID=1600&mapX=3397917&mapY=6491641&scale=4&slices=1
mapsID - city's id(from the set of cities)
mapX/Y - special coordinates in wild format:
Map is a 2^31 2-D array, coordinates are central point + shift * 2^(zoom level+8)
Google Maps:
http://mt.google.com/mt?x=%d&y=%d&zoom=%d
http://maps.google.com/?ie=UTF8&ll=50.352471,30.256348&spn=4.052146,12.44751&z=7
Very simple: long, lat and zoom :)
That's why is not that simple with Maemo mapper.
May be in a few days I'll test and polish what I got now and create special .deb package for Yandex-only mapper, because there are some changes now which break all other map repositories.
Below is a screenshot(click to see 800x480) of what's working at the moment. To be continued!
3 days ago I was forced to leave civilized city and go to the place without Internet(which is 95% of Ukraine, I think). My precious N800 is a perfect toy to spent time with. What I wanted then is to have simple, easy, old, ancient, forgotten. Arcanoid game and I did not find it in . Only via ZX Spectrum emulators, etc...
It's a pity. Had to play Bomberman and NumptyPhysics again all day. So I promise to all who read this. I'll find native arcanoid/krakout and port it to maemo. Because it's classics. It's like to have Windows without solitaire :)
Any idea of what to look for first?
It was too early to release the first version of Labyrinth without proper checking. Even considering "alpha" status of the project. The issue was found almost immediately, though I did not have a time to fix it.
Pygtk in OS2008 and in SDK 4.0 does not support method `to_string` for gtk.gdk.Color, only attributes: "pixel", "red", "green" and "blue". The method is used to store RGB color values like 127/64/0 in hex text "#007f0040000". Can someone advise why it's not working on maemo? The web site says "This method is available in PyGTK 2.12 and above.", however OS2008 contains:
>>> import gtk
>>> gtk.ver
(2, 14, 0)
def color_to_string(color):
return "#00%02x00%02x00%02x" % (color.red, color.green, color.blue)
