google maps - How, exactly does HTML5's GeoLocation work? -

-

I know that the browser shares my IP address and details of nearby wireless networks to determine your location , But what kind of information does it know about nearby WiFi networks?

For example, where I live, there is no public wireless network, and from my house I can see 5 private networks, even if my location is set within 20 meters, there is no open network nearby No, how does Google determine my location? I can think that the only way is that Google mapped the locations of all the wireless networks that map to roads for road view.

I have searched online, but I can not find any specific details

The data sent by Firefox to Google all visible access points, public or private . For each access point, this sends the following data to https://www.google.com/loc/json : 

  "mac_address": "01 "," Signal_Strength ": 8," Age ": 0," SSID ":" MyAccessPoint "

Where

  • mac_address The MAC address of the WiFi node.
  • sign_stream is current
  • age after the WiFi node Is the number of milliseconds.
  • SSID is the name or WiFi node.

Your request was geographical WiFi data used to geocode.

It is important to keep in mind that, however, using Google's Geolocation Services, HTML5's Geolocation API on Firefox is prohibited. This is an implementation, not a specification. If your device has a built-in GPS, it is possibly desirable that your HTML5 implementation will tell the GPS directly instead of using a geographic location service.

Even Firefox applies this feature differently to Windows and Linux. Using Windows's current Firefox, details of all visible WiFi nodes are sent to Google. Using the current Firefox on Linux, the details of connected WiFi nodes are currently being sent due to access point data.

Another responder has said that the use of Safari is a service that works just as Google's Location Services

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
