GPS Updater — accelerate the speed of the GPS fix for Android without mobile Internet

As you know, the "bare" GPS during cold start without external help, gets the coordinates for 3-12 minutes. This is due to the fact that the dataset with coordinates of satellites is transmitted by each satellite is 12.5 minutes. Taking data simultaneously from several satellites this time can be reduced, but it still is quite large.

Phones under Android is no exception. When you start for example Yandex.Card, your Android via mobile Internet trying to get the accurate time, and download through the Internet the parameters of the satellite orbits (almanac and ephemeris). With this information the coordinates can be obtained in just a few seconds.

Usually the problem with capturing speed of GPS coordinates trying to solve by edit the gps file.conf (which requires Lutovinovo phone) — for example there can be mentioned non-working NTP servers. But what if mobile Internet is not at all?

To solve this problem, I asked a colleague Xonder to write a program GPS Updater, which according to the schedule downloads the Almanac over the home WiFi (if necessary, including WiFi, and then turning it off) that provides the time coordinates during the day ~5-45 seconds. As a side effect — all apps, downloaded mail, and so on.

In addition, the program can turn on WiFi and update the Almanac while charging, when electricity is not sorry. And all this free download with no ads for free. I hope this program will be helpful to some readers.

Importantly, the program does not take memory at all — it is run only to handle events (like connection of charging or the time of scheduled updates).

Wikia Search — first impressions

Изображение
Today, January 7, as promised, was launched search engine Wikia Search , still only in alpha version. ( edit Angela Beasley at 06:58 UTC or 09:58 Moscow time.) Of bugs: when searching in Russian (for example, the word habrahabr ) there are errors with the coding, although it seems that everything is in utf-8. Users who have an account on Wikia, you can login with the same username, but properties users flew in Wikia Search Alpha, and on the Wikia website. About search: while search (English queries), you can create ministate (miniarticles). Next to the search result indicates the number like 1.26 (something like pagerank'a or TIC), clicking on which shows how it was counted. When you hover over the number next to it shows the stars, which don't work (looks like that will be implemented by the ranking of results). It is unclear how results are ranked, because the query " George Bush " first gets a website "George Bush Is A Crackwhore!" wit...

Emulator data from GNSS receiver NMEA

Изображение
Introduction I had the need to test an application that uses the GNSS data NMEA. was Due to the fact that worked on the project navigation of the aircraft, test the air expensive naturally on earth to drive a car with a GNSS receiver is not particularly convenient, that like sitting at the table to have a virtual parallel port data Protocol NMEA allegedly moving equipment. First, search for different software had to try and find something suitable, but most paid and control of the emulation data is not very convenient, although practically emulate all settings of the NMEA standard. But I needed something simple emulating coordinates, speed, in principle, nothing more was required quite convenient and logical control. So I had to write an app of this kind in C#. Fly_nmea NMEA ("National Marine Electronics Association") — the full name is "NMEA 0183" is a text communication Protocol, marine (typically navigation) equipment together. Data is transmit...

mSearch: search + filter for MODX Revolution

Изображение
Something blog MODX habré completely withered, we need to spice things up. I want to introduce you to your component, which has recently been almost completely rewritten and expanded. It's called mSearch and originally conceived as a simple site search with account of morphology of the Russian language. That is, you had a quick and easy solution for any site without installing Sphinx and other major systems. In the process gugleniya, I came across a interesting this task by phpMorphy . Full text search on a table with an index, with the generation of different word forms. The idea I liked, by my criteria it came up and I wrote my solution, basing this method. the mSearch This snippet and plugin. The snippet is looking for the plug-in index documents when saving. Installation, as usual, from the repository, in 4 clicks. At the same time, you will be prompted to download and install for phpMorphy dictionaries of the Russian language — do not give up. ...
