  • best way to implement a deck for a card game in python

    - by matt1024
    What is the best way to store the cards and suits in python so that I can hold a reference to these values in another variable? For example, if I have a list called hand (cards in players hand), how could I hold values that could refer to the names of suits and values of specific cards, and how would these names and values of suits and cards be stored?

  • WinSock best accept() practices

    - by Meta
    Imagine you have a server which can handle only one client at a time. The server uses WSAAsyncSelect to be notified of new connections. In this case, what is the best way of handling FD_ACCEPT messages: A Accept the connection attempt right away but queue the client until its turn? B Do not accept the next connection attempt until we are done serving the currently connected client? What do you guys think is the most efficient?

  • Android: get current location from best available provider

    - by AP257
    Hi all, I have some Android code that needs to get the best available location QUICKLY, from GPS, network or whatever is available. Accuracy is less important than speed. Getting the best available location is surely a really standard task. Yet I can't find any code to demonstrate it. The Android location code expects you to specify criteria, register for updates, and wait - which is fine if you have detailed criteria and don't mind waiting around. But my app needs to work a bit more like the Maps app does when it first locates you - work from any available provider, and just check the location isn't wildly out of date or null. I've attempted to roll my own code to do this, but am having problems. (It's inside an IntentService where an upload happens, if that makes any difference. I've included all the code for info.) What's wrong with this code? @Override protected void onHandleIntent(Intent arg0) { testProviders(); doUpload(); } private boolean doUpload() { int j = 0; // check if we have accurate location data yet - wait up to 30 seconds while (j < 30) { if ((latString == "") || (lonString == "")) { Log.d(LOG_TAG, "latlng null"); Thread.sleep(1000); j++; } else { Log.d(LOG_TAG, "found lat " + latString + " and lon " + lonString); break; } //do the upload here anyway, with or without location data //[code removed for brevity] } public boolean testProviders() { Log.e(LOG_TAG, "testProviders"); String location_context = Context.LOCATION_SERVICE; locationmanager = (LocationManager) getSystemService(location_context); List<String> providers = locationmanager.getProviders(true); for (String provider : providers) { Log.e(LOG_TAG, "registering provider " + provider); listener = new LocationListener() { public void onLocationChanged(Location location) { // keep checking the location - until we have // what we need //if (!checkLoc(location)) { Log.e(LOG_TAG, "onLocationChanged"); locationDetermined = checkLoc(location); //} } public void onProviderDisabled(String provider) { } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } }; locationmanager.requestLocationUpdates(provider, 0, 0, listener); } Log.e(LOG_TAG, "getting updates"); return true; } private boolean checkLoc(Location location) { float tempAccuracy = location.getAccuracy(); int locAccuracy = (int) tempAccuracy; Log.d(LOG_TAG, "locAccuracy = " + locAccuracy); if ((locAccuracy != 0) && (locAccuracy < LOCATION_ACCURACY)) { latitude = location.getLatitude(); longitude = location.getLongitude(); latString = latitude.toString(); lonString = longitude.toString(); return true; } return false; } public void removeListeners() { // Log.e(LOG_TAG, "removeListeners"); if ((locationmanager != null) && (listener != null)) { locationmanager.removeUpdates(listener); } locationmanager = null; // Log.d(LOG_TAG, "Removed " + listener.toString()); } @Override public void onDestroy() { super.onDestroy(); removeListeners(); } Unfortunately, this finds the network provider, but only ever outputs latlng null 30 times - it never seems to get a location at all. I never even get a log statement of locationChanged. It's funny, because from ddms I can see output like: NetworkLocationProvider: onCellLocationChanged [305,8580] NetworkLocationProvider: getNetworkLocation(): returning cache location with accuracy 75.0 seeming to suggest that the network provider does have some location info after all, I'm just not getting at it. Can anyone help? I think working example code would be a useful resource for the Android/StackOverflow community.

  • Best SEO practices for mobile URLs: 301, rel=canonical, or something else?

    - by Chris
    I am developing a site with a mobile version and am trying to figure the appropriate way to manage the URLs for search engines. So far I've considered: Having a mobile site with rel="canonical" links to the regular site. Putting both the mobile site and full site on one URL, and doing user agent sniffing. Another opinion: Spencer: "If you have a mobile site at a separate location or URL, you should 301 redirect each and every mobile page to its corresponding page on your main website. Employ user agent detection so that the mobile optimized version is served up if someone's coming in from a hand-held. - http://developer.practicalecommerce.com/articles/1722-Mobile-site-Development-Best-Practices-for-SEO-Usability Both 2 and 3 make it hard for a user who wants to switch to the full site or mobile site manually, but I'm not sure 1 is the best alternative. What's the best way to write URLs for a mobile site?

    I am developing a site with a mobile version and am trying to figure the appropriate way to manage the URLs for search engines. So far I've considered: Having a separate mobile site (m.example.com) with rel="canonical" links to the regular site. Putting both the mobile site and full site on one URL (example.com), and doing user agent sniffing.

  • What software development model has worked best for software teams with heavy dependancy on hardware teams?

    - by MasterDIB
    So, let me explain more. There are a number of competing best practices for software development. I can find that many teams have benefited from Agile practices in some cases. In some other cases, using the Unified Process has been championed by large companies like IBM. The common themes that I find seemed to work well for teams that mainly develop software. I am interested to know what has worked best for people who have worked in shops where there is a team on the other side that produce the hardware that your software is running on. For example, one team puts together a crate with several custom hardware on it; while you need to develop the software that would run on those crates. I can't find a development model (agile, spiral ...) that works best in this case. Any wisdom is this area will be well appreciated.

  • What is the Best Way to Incentivize a Team of Developers?

    - by Seth P.
    I know in advance that people are going to see this question and think "free Red Bull." But I am actually looking for the best way to tie rewards for developers to the company's long-term goals. For example, assuming a team is working on the same software product, would it be best to reward each developer based on the condition of the final product? They are a team after all, and this will ensure that they are all working towards the common goal of getting the product out. However, this ignores the fact that some developers are stronger than others and some work harder than others. In your experience, what is the best way to incentivize a team of developers?

  • Best way to get InnerXml of an XElement?

    - by Mike Powell
    What's the best way to get the contents of the mixed "body" element in the code below? The element might contain either XHTML or text, but I just want its contents in string form. The XmlElement type has the InnerXml property which is exactly what I'm after. The code as written almost does what I want, but includes the surrounding <body>...</body> element, which I don't want. XDocument doc = XDocument.Load(new StreamReader(s)); var templates = from t in doc.Descendants("template") where t.Attribute("name").Value == templateName select new { Subject = t.Element("subject").Value, Body = t.Element("body").ToString() };

  • Django - How best to handle ValidationErrors after form.save(commit=False)

    - by orokusaki
    This is a fragment of my code from a view: if form.is_valid(): instance = form.save(commit=False) try: instance.account = request.account instance.full_clean() except ValidationError, e: # Do something with the errors here... I don't know what the best thing to do here is, but I certainly don't want to do it 180 times. This is an utter mess. Who would want to handle validation errors manually in every view. If you're not modifying the instance after save(commit=False), you don't have to worry about this, but what about in my case where every model has a foreign key to account which is set behind the scenes and hidden from the user? Any help is really appreciated.

  • Best "For Pay" wpf controls

    - by Vaccano
    If this question has been asked then I applogize and I will join in voting to close it (or just delete it), but I could not find it being asked before. We are potentially embarking on making many of our apps using WPF. Most of our apps are normal business apps that will not need too much eye candy. Tasteful ui is nice, but I don't see us doing lost of custom animations and such. So, my question is what 3rd party control sets are the best ones to purchase to save you time in development of apps like this? (These should work with both Visual Studio 2008 and 2010.)

  • Best practice to calculate the average speed from GPS coordinates

    - by Sebi
    i have here a device which can give me gps coordinates. the time intervall i can define. i want to use it to calculate the average speed during driving or travelling by car. actually i used a orthodrome formula to calculate the distance between two points and then divided it by the given time intervall. by the implemenation i followed this term (http://de.wikipedia.org/wiki/Orthodrome#Genauere_Formel_zur_Abstandsberechnung_auf_der_Erde). Unfortunately i could only find a german link, but i think the formula should be understandable in any language ;) Unfortunately, using this formula and a time intverall of 1 seconds gives very unprecises results. the speed while walking is between 1 km/h and 20km/h. So i wonder if there is a general reference how to implement distance calculation between two gps coordinates (i found something similar on SO) and particulary, which is the best time intervall to update the GPS coordiantes.

  • Best practice for Python & Django constants

    - by Dylan Klomparens
    I have a Django model that relies on a tuple. I'm wondering what the best practice is for refering to constants within that tuple for my Django program. Here, for example, I'd like to specify "default=0" as something that is more readable and does not require commenting. Any suggestions? Status = ( (-1, 'Cancelled'), (0, 'Requires attention'), (1, 'Work in progress'), (2, 'Complete'), ) class Task(models.Model): status = models.IntegerField(choices=Status, default=0) # Status is 'Requires attention' (0) by default. EDIT: If possible I'd like to avoid using a number altogether. Somehow using the string 'Requires attention' instead would be more readable.

  • Career advice: I am best at what I hate most

    - by flybywire
    I think my career has entered a vicious circle which I would like to exit: I am best at what I hate most. And because I am good at that, I always receive that kind of assignments, and I do them as expected or even better. Which makes me more of an expert and brings me more similar tasks. My "expertise" is what (I think) every programmer hates: legacy systems. I can very quickly learn systems, and modify them, migrate them, extract web services from them whatever (without breaking them). Never to develop more functionality or to solve interesting or original problems. Just have that work with Java 1.4, or convert it into a rest-full service or support oracle too. I feel (and I am told) that I am highly regarded and very helpful to my company. But I hate what I do. What would you do in my place?

  • the best way to connect sql server (Windows authentication vs SQL Server authentication) for asp.net

    - by Brij
    I have a database and a site having forms authentication. It is working fine with VS2008. This time, I am using "Trusted_connection =True". But when it is opened from outside or directly from browser then I am getting error "Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'." I know this is due to permission. SQL server is based on windows authentication. What is the best approach to manage user to connect SQL Server? Should I enable SQL Server authentication? Let me know what to do so that it makes the production feel and there wouldn't be any problem during deployment. Note: SQL Server is installed on domain server.

  • Best way to cache resized images using PHP and MySQL

    - by Chris Hawes
    What would be the best practice way to handle the caching of images using PHP. The filename is currently stored in a MySQL database which is renamed to a GUID on upload, along with the original filename and alt tag. When the image is put into the HTML pages it is done so using a url such as '/images/get/200x200/{guid}.jpg which is rewritten to a php script. This allows my designers to specify (roughly - the source image maybe smaller) the file size. The php script then creates a hash of the size (200x200 in the url) and the GUID filename and if the file has been generated before (file with the name of the hash exists in TMP directory) sends the file from the application TMP directory. If the hashed filename does not exist, then it is created, written to disk and served up in the same manner, Is this efficient as it could be? (It also supports watermarking the images and the watermarking settings are stored in the hash as well, but thats out of scope for this.)
