  • Does a Category applied to NSString also apply to NSCFString via the "toll-free bridge"?

    - by half_brick
    We're integrating a library into an iPhone app which appears to use the google toolbox for iPhone internally. The google toolbox adds a method gtm_stringBySanitizingAndEscapingForXML to NSString. The problem is, whenever we attempt to make a call to this library we get [NSCFString gtm_stringBySanitizingAndEscapingForXML]: unrecognized selector sent to instance 0x272478 So it appears the library is calling that method on a NSCFString, to which the category does not apply. So... is it the case that the category will not apply across the toll-free bridge to CoreFoundation classes? If that's the case then we at least know why it's blowing up. Figuring out how to fix it is a different matter.

  • SEO: It's recommended to upload and put live a beta / non-finished version of web site??

    - by Jonathan
    I'm working on this big website and I want to put it online before its fully finished... I'm working locally and the database is getting really big so I wanted to upload the website and continue to work on it in the server, but allowing people to enter, so I can test. The question is if this is good for SEO, I mean, there are a lot of things SEO related that are incomplete.. For example: there are no friendly URLs, no sitemap, no .htacces file, lot of 'in-construction' sections... Does Google will penalize me forever? How does it works? Google indexes adn get the structure of the site just once or its constantly updating and checking for changes??? What i should do? What you recommend?!!?

  • Indexing Bilingual Sites

    - by Affar
    Hi all I have a site that supports two languages. The way the user changes the language is by clicking on a language link that will change his session language from A to B and return him to the same page. The problem that I am facing is that Google doesn't index the other language since it is seeing that the language link is the same as the page link but with changes in the parameters. So is there a way to inform google of the language, or should I add the language in the url, i.e. www.example.com/A/home?

  • How to get sites identical in content but different in language and TLD indexed by major search engi

    - by mojo77
    Hi! Is it possible to get two "editions" of a website both indexed by the major search engines (Google/Yahoo/Bing/Teoma) which differ in content language only and are hosted under different TLDs? Say English content is available at "http://domain.com/", German content at "http://domain.de/". Now, if e.g. Google.com is used I want it to list the "domain.com" entry and vice versa. Is "Duplicate Content" an issue here? Thanks so much for advising me!

  • AppEngine GeoPt Data Upload

    - by Eric Landry
    I'm writing a GAE app in Java and only using Python for the data upload. I'm trying to import a CSV file that looks like this: POSTAL_CODE_ID,PostalCode,City,Province,ProvinceCode,CityType,Latitude,Longitude 1,A0E2Z0,Monkstown,Newfoundland,NL,D,47.150300000000001,-55.299500000000002 I was able to import this file in my datastore if I import Latitude and Longitude as floats, but I'm having trouble figuring out how to import lat and lng as a GeoPt. Here is my loader.py file: import datetime from google.appengine.ext import db from google.appengine.tools import bulkloader class PostalCode(db.Model): id = db.IntegerProperty() postal_code = db.PostalAddressProperty() city = db.StringProperty() province = db.StringProperty() province_code = db.StringProperty() city_type = db.StringProperty() lat = db.FloatProperty() lng = db.FloatProperty() class PostalCodeLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'PostalCode', [('id', int), ('postal_code', str), ('city', str), ('province', str), ('province_code', str), ('city_type', str), ('lat', float), ('lng', float) ]) loaders = [PostalCodeLoader] I think that the two db.FloatProperty() lines should be replaced with a db.GeoPtProperty(), but that's where my trail ends. I'm very new to Python so any help would be greatly appreciated.

  • How do I check for Existence of a Record in GAE

    - by VDev
    I am trying to create a simple view in Django & GAE, which will check if the user has a profile entity and prints a different message for each case. I have the program below, but somehow GAE always seem to return a object. My program is below import datetime from django.http import HttpResponse, HttpResponseRedirect from google.appengine.api import users from google.appengine.ext import db from models import Profile import logging #from accounts.views import profile # Create your views here. def login_view(request): user = users.get_current_user() profile = db.GqlQuery("SELECT * FROM Profile WHERE account = :1", users.get_current_user()) logging.info(profile) logging.info(user) if profile: return HttpResponse("Congratulations Your profile is already created.") else: return HttpResponse("Sorry Your profile is NOT created.") My model object is Profile defined as follows: class Profile(db.Model): first_name = db.StringProperty() last_name = db.StringProperty() gender = db.StringProperty(choices=set(["Male", "Female"])) account = db.UserProperty(required = True) friends = db.ListProperty(item_type=users.User) last_login = db.DateTimeProperty(required=True) Thanks for the help.

    - by lance_klusener
    Hello All, I am new to web application development, so sorry in advance if this question is too basic. The following are the details of the question: A] Platform being used -- google app engine with python, django. B] Tutorial link being used -- http://code.google.com/appengine/articles/djangoforms.html C] Question: In the application i am building, there is a drop down box which allows the user to select their country. Since the list of countries is above 200, i want to construct a database of the countries before the application loads. Once this application is deployed, i dont want the database to get re-loaded again, since the entries are constant for all the users. How does one achieve this ? thanks, Lance.

  • NoneType has no attribute Append

    - by Rosarch
    I'm new to Python. I can't understand why a variable is None at a certain point in my code: class UsersInRoom(webapp.RequestHandler): def get(self): room_id = self.request.get("room_id") username = self.request.get("username") UserInRoom_entities = UserInRoom.gql("WHERE room = :1", room_id).get() if UserInRoom_entities: for user_in_room in UserInRoom_entities: if user_in_room.username == username: user_in_room.put() # last_poll auto updates to now whenenever user_in_room is saved else: user_in_room = UserInRoom() user_in_room.username = username user_in_room.put() UserInRoom_entities = [] UserInRoom_entities.append(user_in_room) // error here # name is `user_at_room` intead of `user_in_room` to avoid confusion usernames = [user_at_room.username for user_at_room in UserInRoom_entities] self.response.out.write(json.dumps(usernames)) The error is: Traceback (most recent call last): File "C:\Program Files\Google\google_appengine\google\appengine\ext\webapp\__init__.py", line 507, in __call__ handler.get(*groups) File "path\to\chat.py", line 160, in get AttributeError: 'NoneType' object has no attribute 'append' How is this possible? I'm setting UserInRoom_entities = [] immediately before that call. Or is something else the None in question?

  • Android: Maps - Best way to provide 'search for location' feature?

    - by r3mo
    Hello all, I've got an android app that uses a map activity and serves up content based on map location. I'm looking for a way to allow the user to search for a location by name (anything from 'New York' to 'Eiffel Tower') - e.g. have a text input field into which they could type 'Rome' - after pressing a button, the user would be brought to the coordinates of Rome on the map. What would be the best way to go about this? I've looked into the google geocoding api (http://code.google.com/apis/maps/documentation/geocoding/), but it has limitations of 2,500 geolocation requests per day - I'm presuming this is per API key? Or is it per user/source IP? 2,500 requests for one android app woudln't last long. Ideally, I would be able to search for English and foreign names of countries. Thanks in advance! r3mo

  • Place text based divs in relative locations within a circle

    - by NickG
    Direct question - How would I place certain objects or small text within a certain area. For example, how would I replace the following image with html/javascript. --- I don't have enough reps to post an image :/ but try this URL - http://i.imgur.com/a3eWL.jpg Big picture - I am trying to create a kml file for Google Earth that when the point is clicked, the balloon description window pops up and I can display my html formatted diagram showing where the satellites are at that instant. Google Earth and KML docs allow for pretty much any html formatting within it, so currently looking for a good way to do this. Disclaimer: It has been a few years since i have done any html or javascript editing, so general examples and insight is greatful. Thanks

  • Objectify - Retrieve subclass instances with superclass query

    - by Deviling Master
    for a project i'm making, i'm using Objectify and Google AppEngine I'm quoting and old message from Google Groups, but the problem i have is the same: Here's the problem I'm trying to solve: I'd like to persist instances of several subclasses of one superclass to the datastore, and then retrieve them by querying for that superclass. (For example, a query for Game would return instances of Chess and Backgammon). Is there any way to accomplish this using Objectify? Because the thing i want is the same, but the topic does not provides yet an answer (it's 3 years old), I moved here with the same question. From 2010 to now, this question has been solved? Thanks Bye

  • HTML5 Search Input: No Background Image in Chrome?

    - by Jason
    I have been pulling my hair out trying to get Chrome to style my search input with a background image. Firefox has no problem, but I fear it's because it treats the input as a regular text input. Is this simply not possible? Try this as a demo: <input type="search" /> ?input[type="search"] { background: transparent url(http://google.com/intl/en_ALL/images/srpr/logo1w.png) no-repeat 0 0; }?????? If it worked correctly, it should put Google's logo (or part of it) as the background image for the "Search" input. But as you will see when you look at this in Chrome, it DOES NOT WORK. Any ideas, or is this just one of HTML5's quirks? :\

  • UnicodeDecodeError from a GET-parameter in webapp2

    - by Aneon
    I'm getting a UnicodeDecodeError when recieving a GET-parameter from webapp2 that contains unicode characters, and then using it to do a NDB query. I get the same error message when manually running a unicode() on the parameter in the handler, so there either seems to be a problem in webapp2's URL routing or I've missed something. Preferably, all GET-parameters should be converted to unicode before getting passed into the handler so I don't need to do manual conversions in all of my handlers. I actually think it's worked before in an earlier version. The full error message read: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128) The GET-parameter contains the following string: göteborg. It looks fine when I raise an Exception on it, but gives me an error when I (or NDB) use unicode() on it. EDIT: In NDB, it fails on the following code: File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\datastore_types.py", line 1562, in PackString pbvalue.set_stringvalue(unicode(value).encode('utf-8')) Thanks.

  • How can I modify this javascript code?

    - by TIMEX
    I'm using the Google Local Search API and Google Maps API. See here: http://geodit.com:8000/test You can perform a search, and then the javascript fills the Map, as well as the results next to the map. I think this function fills the results next to the map: function OnLocalSearch() My question is: how can I change the results displayed? Right now, by default it shows the Name of the business and the address. How can I disable the business link? And then add more text to each search result?

  • How to get wireless (Alfa) operate in full power and speed up wireless Internet?

    - by MahboobeAlam
    I am using Wireless to connect to the internet (router). My laptop has Atheros wireless (AR 242x/542x) adapter but the router is a little bit far-away from my room so I have to use an external wireless adapter i.e. Alfa (Realtek 8187) for connectivity. However, since I have started using Ubuntu I noticed that Alfa is not working in full power, internet speed in Ubuntu is much slower than in Windows on my laptop. When I am using Windows 7 the LED (bulb) on Alfa blinks as it should, but when in Ubuntu, it doesn't blink rather it is on but very dim. Connection using Atheros adapter is also the same (slow)... I have tried 4 methods (I found on the Internet) to troubleshoot this matter but no success. It seems to me that Ubuntu/Linux is not letting these wireless adapters to operate in full strength. iwconfig shows that power management is off for both. So what's the problem?

  • Does OO, TDD, and Refactoring to Smaller Functions affect Speed of Code?

    - by Dennis
    In Computer Science field, I have noticed a notable shift in thinking when it comes to programming. The advice as it stands now is write smaller, more testable code refactor existing code into smaller and smaller chunks of code until most of your methods/functions are just a few lines long write functions that only do one thing (which makes them smaller again) This is a change compared to the "old" or "bad" code practices where you have methods spanning 2500 lines, and big classes doing everything. My question is this: when it call comes down to machine code, to 1s and 0s, to assembly instructions, should I be at all concerned that my class-separated code with variety of small-to-tiny functions generates too much extra overhead? While I am not exactly familiar with how OO code and function calls are handled in ASM in the end, I do have some idea. I assume that each extra function call, object call, or include call (in some languages), generate an extra set of instructions, thereby increasing code's volume and adding various overhead, without adding actual "useful" code. I also imagine that good optimizations can be done to ASM before it is actually ran on the hardware, but that optimization can only do so much too. Hence, my question -- how much overhead (in space and speed) does well-separated code (split up across hundreds of files, classes, and methods) actually introduce compared to having "one big method that contains everything", due to this overhead? UPDATE for clarity: I am assuming that adding more and more functions and more and more objects and classes in a code will result in more and more parameter passing between smaller code pieces. It was said somewhere (quote TBD) that up to 70% of all code is made up of ASM's MOV instruction - loading CPU registers with proper variables, not the actual computation being done. In my case, you load up CPU's time with PUSH/POP instructions to provide linkage and parameter passing between various pieces of code. The smaller you make your pieces of code, the more overhead "linkage" is required. I am concerned that this linkage adds to software bloat and slow-down and I am wondering if I should be concerned about this, and how much, if any at all, because current and future generations of programmers who are building software for the next century, will have to live with and consume software built using these practices. UPDATE: Multiple files I am writing new code now that is slowly replacing old code. In particular I've noted that one of the old classes was a ~3000 line file (as mentioned earlier). Now it is becoming a set of 15-20 files located across various directories, including test files and not including PHP framework I am using to bind some things together. More files are coming as well. When it comes to disk I/O, loading multiple files is slower than loading one large file. Of course not all files are loaded, they are loaded as needed, and disk caching and memory caching options exist, and yet still I believe that loading multiple files takes more processing than loading a single file into memory. I am adding that to my concern.
