I don't agree with them, as i'd rather get something done, but just so you know.</p> <p>WADL is a description of a web service API, a little like WSDL is for SOAP type web services, that is designed to be more in tune with RESTful interfaces (something WSDL is poor at).</p> <p>It's primary usage in my experience is to allow you to generate client code that can call the service (handy if it's a very large API, which literally saves hours of work). It also serves the purpose of documenting a REST-like interface.</p> |

Android is designed to keep processes in background to start them quickly once user want to go back to you app. </p> <p>You should not rely that your app will be terminated to fix some memory leaks. There are tools to fix them, like dumping HPROF file and using memory analyzer, also using weak references, and using good programming practicies - mostly not leaking activities.</p> <p>[edit] - there are resources that are not always freed on process end, while working with android TTS apis, I found that after few app crashes I have to reset device to be able to use svox voices.</p> |

37,736,662 | 1 | Django Best Practice for Handling Related Model Objects Between Apps <p>I have a project that has 2 different apps. One handles a site's performance metrics and the other estimates site's workload. The workload app has some dependencies on the performance app. However, I am trying to avoid creating a dependency from the metrics app to the workload app in order to better encapsulate the metrics app as stand-alone. For example, metrics has this model:</p> <pre><code># models.py in metrics app: class Site(models.Model): site_name = models.CharField(max_length=255) site_geography = models.CharField(max_length=255) slug = AutoSlugField(populate_from='site_name', unique=True, null=True) </code></pre> <p>Workload app has objects such as (some omitted for brevity):</p> <pre><code># models.py in workload app: class Resource (models.Model): name_first = models.CharField(max_length=60) name_last = models.CharField(max_length=60) address_street = models.CharField(max_length=80, blank=True) address_city = models.CharField(max_length=40, blank=True) address_state = models.CharField(max_length=2, blank=True) sites = models.ManyToManyField(metrics_models.Site, through='ResourceSiteRelationship', blank=True, related_name='resources') class Activity (models.Model): activity_name = models.CharField(max_length=255) hours = models.DecimalField(max_digits=5, decimal_places=2) travel = models.BooleanField() description = models.TextField(blank=True) class ResourceSiteRelationship (models.Model): roles = models.ManyToManyField(Role, blank=True, related_name='resource_site_relationships') resource = models.ForeignKey(Resource, on_delete=models.CASCADE, blank=True, null=True, related_name='resource_site_relationships') site = models.ForeignKey(metrics_models.Site, on_delete=models.CASCADE, blank=True, null=True, related_name='resource_site_relationships') </code></pre> <p>Site should also have the following field relationship:</p> <pre><code>activities = models.ManyToManyField(Activity, related_name='sites', blank=True) </code></pre> <p>Is it best to add that field to the metric's app's instance of Site? Is it better to create a one-to-one class for Site in the workload app and extend like so:</p> <pre><code>class Site(models.Model): site = models.OneToOneField(metrics_models.Site, on_delete=models.CASCADE) activities = models.ManyToManyField(Activity, related_name='sites', blank=True) </code></pre> <p>Or is there another way to do this?</p> |

I guess I could make this option work, if anyone would point me how to throw in strong params into a self. controller method.</p> <p>My option 2:</p> <p>I then decided to move the whole action into my User model like this</p> <p>Contoller:</p> <pre><code> def create @user = current_app_user @user.delay.create_and_email(link_share_params) respond_to do |format| format.js {} end end </code></pre> <p>Model:</p> <pre><code> def create_and_email link_share = self.link_shares.build(**params**) link_share.save end </code></pre> <p>Again, trouble with the strong params. How would I go with importing my params into the model? Should I just chain them as arguments? </p> <p>Any advice appreciated</p> |

If it's a true array, you should make it a <code>Collection</code>.

You want to see if the line contains any of the words in the array. What you want then is something like this:</p> <pre><code>BufferedReader in = null; Set<String> words = ... // construct this as per above try { in = ... while ((String line = in.readLine()) != null) { for (String word : words) { if (line.contains(word)) [ // do whatever } } } } catch (Exception e) { e.printStackTrace(); } finally { if (in != null) { try { in.close(); } catch (Exception e) { } } } </code></pre> <p>This is quite a crude check, which is used surprisingly open and tends to give annoying false positives on words like "scrap". For a more sophisticated solution you probably have to use regular expression and look for word boundaries:</p> <pre><code>Pattern p = Pattern.compile("(?<=\\b)" + word + "(?=\b)"); Matcher m = p.matcher(line); if (m.find() { // word found } </code></pre> <p>You will probably want to do this more efficiently (like not compiling the pattern with every line) but that's the basic tool to use.</p> |

20,874,391 | 1 | Django / Python: Real time peer to peer chat messaging <p>I use Django and Gunicorn to power my front end iOS applications. Up until now, I've been using simple GET, PUT, POST requests to send and receive json data from my iOS application to my Django server and vice versa. </p> <p>This setup has been solid however, I would like to implement real time messaging. When I first started out, I used APNS (Apple's Push Notifications Service) to deliver messages real time to recipients. Here is an example of what I used to do:</p> <p>If UserA messaged UserB, I would send the message to the Django Server via JSON, process it in a Django view, use <a href="https://github.com/samuraisam/pyapns">pyAPNS</a> - a python wrapper for APNS and it would send a push notification to UserB (the recipient) along with a payload size of 256 bytes. This worked well however it also has a few cons. </p> <p>If the recipient chooses to disable push notifications, then they will not receive the message. When you implement core data in your iOS app, this can be quite messy if you cache objects.</p> <p>So this leaves me with another option. Building something that is socket based that can work with Django and send the payload as JSON. Any ideas?</p> |

4,531,853 | 0 | <p>It sounds like your problem is more related to developing on Windows than the Android SDK itself. I got it up and running pretty quickly on my 64 bit Win7 box, but I really prefer to develop in Linux. Once I sorted some silly issues with eclipse dependencies out, it was incredibly simple to run and keep updated.</p> <p>I suspect most hardcore android devs (and the people who build the tools at Google) run Linux of some flavor on their boxes - so it isn't surprising that the tools work well there.</p> <p>Eclipse isn't really the alpha version of websphere - it's a perfectly usable and stable tool in it's own right. Fedora isn't the alpha for RHEL either - it's just more bleeding edge. You can run a perfectly stable Fedora system, but most companies go with RHEL because of the support options.</p> <p>The Android plugins and SDKs are certainly under active development, which is a good thing. That doesn't necessarily make them Beta quality.</p> <p>Eclipse is used incredibly widely. It's adequately tested. The Android SDKs work just fine for a majority of users. I'm sorry you had problems with them, but as you admitted, you're running an unusual configuration. </p> <p>Windows is designed to run with every user as an administrator - Development tools usually assume this, with hardware development tools doubly so. It's a reasonable assumption. Even under Linux, Android development really works better with root access. You're trying to do things with the underlying hardware that normal users shouldn't be able to do.</p> |

1,896,709 | 0 | <p>If you really mean ASCII, you can't possibly rescue Hebrew characters. ASCII is only the 7-bit character set up to <code>\x7F</code>.</p> <p>So what kind of strings does this Windows program read? If it's ASCII, or Latin-1, you'll never get Hebrew. More likely it's “the current system code page”, also (misleadingly but commonly) known in Windows as ‘ANSI’.</p> <p>If that's the case you will have to set the system code page on every machine that runs the Windows program to Hebrew (code page 1255). I believe shp files have no character encoding information at all, so the shapefiles will only ever work correctly on machines with this code page set (the default only in the Israel locale). (Apparently <code>.dbf</code> exports can have an accompanying <code>.cpg</code> file to specify the encoding, but I've no idea if the program you're using supports that.)</p> <p>Then you'd have to export the data as code page 1255, or the nearest you're going to get in Postgres, ISO-8859-8. Since the export script doesn't seem to have any option to do anything but take direct bytes from the database, you'd have to create a database in the ISO-8859-8 encoding and transfer all the data from the UTF-8 database to the 8859-8 one, either directly through queries or, perhaps easier, using <code>pgdumpall</code> and loading the SQL into Notepad then re-saving it as Hebrew instead of UTF-8 (adjusting any encoding settings listed in SQL DDL as you go).</p> <p>I wonder if the makers of the Windows program could be persuaded to support UTF-8? It's a bit sad to be stuck with code-page specific software in this century.</p> |

39,956,077 | 0 | reading in csv file and storing in arrays <p>the practice question i got says that i need to</p> <p>create a java code that reads in csv file with name and height. </p> <p>to read a file you must get a file name from user as string. </p> <p>then you must store contents of file into two arrays one for name (string) and height(real number).</p> <p>You should read the file at least twice, once to check how many students are in the file (so you know how many students you need to store) and a couple more times to actually read the file (to get the names and height).</p> <p>then prompt the user for name you want height of. it should output the height for userinput.</p> <p>example csv file is </p> <p>chris,180</p> <p>jess,161</p> <p>james, 174</p> <p>its not much but this is all i could come up with i have no idea how to store name and height separately and use that array to output the results. and would i need to use split somewhere in the code? i remember learning it but dont know if its used in this situation</p> <pre><code>import.java.util.*; private class StudentNameHeight private void main (string [] args) { String filename; Scanner sc = new scanner(system.in); System.out.println("enter file name") filename = sc.nextline(); readFile (filename); } private void readFile (String filename) { FileInputStream fileStrm = null; InputStreamReader rdr; BufferedReader bufRdr; try { fileStrm = new FileInputStream(filename); rdr = new InputStreamReader(fileStrm); bufRdr = new BufferedReader(rdr); // ? catch (IOException e) { if (fileStrm != null) { try {fileStrm.close(); } catch (IOException e2){} } System.out.println("error in processing" + e.getMessage()); } } </code></pre> <p>im new to java so, any small tip or help would be great </p> <p>thanks</p> |

18,091,654 | 0 | <p>This is a specific case of the general CSV parsing problem. The general solution is provided by Lorance Stinson (google <code>Stinson awk CSV parser</code>) but IMHO the simplest way to deal with this specific issue is to convert newlines within double quotes to some other character, do whatever you want with the file in single-line-per-record format, then convert back, e.g.:</p> <pre><code>$ cat file "Test_data1" "Test_data2" "1s" "452" "Test data643" " " "4d" "System" "Institute" "Test_data3" "Test_data4" "2s" "563" "Test data754" " " "5d" "Non System" "Association" </code></pre> <p>To convert to single line:</p> <pre><code>$ awk -v FS= '{for (i=1;i<=NF;i++) if ($i=="\"") inQ=!inQ; ORS=(inQ?"♥":"\n") }1' file "Test_data1" "Test_data2" "1s" "452" "Test♥data643" "♥" "4d" "System" "Institute" "Test_data3" "Test_data4" "2s" "563" "Test♥data754" "♥" "5d" "Non System" "Association" </code></pre> <p>and to convert back is a simple <code>tr</code>:</p> <pre><code>$ awk -v FS= '{for (i=1;i<=NF;i++) if ($i=="\"") inQ=!inQ; ORS=(inQ?"♥":"\n") }1' file | tr '♥' ' \n' "Test_data1" "Test_data2" "1s" "452" "Test data643" " " "4d" "System" "Institute" "Test_data3" "Test_data4" "2s" "563" "Test data754" " " "5d" "Non System" "Association" </code></pre> <p>The above uses control-C as a replacement for the newline within quotes, pick whatever character you like (or string if you want to use awk or sed rather than tr to convert back to newlines).</p> <p>Just insert the command to do whatever you want with your original file in between the awk and the tr, e.g. sort in reverse:</p> <pre><code>$ awk -v FS= '{for (i=1;i<=NF;i++) if ($i=="\"") inQ=!inQ; ORS=(inQ?"♥":"\n") }1' file | sort -r | tr '♥' '\n' "Test_data3" "Test_data4" "2s" "563" "Test data754" " " "5d" "Non System" "Association" "Test_data1" "Test_data2" "1s" "452" "Test data643" " " "4d" "System" "Institute" </code></pre> |

7,098,736 | 0 | <p>The default resizing method used by <code>thumbnail</code> is NEAREST, which is a really bad choice. If you're resizing to 1/5 of the original size for example, it will output one pixel and throw out the next 4 - a one-pixel wide line has only a 1 out of 5 chance of showing up <em>at all</em> in the result!</p> <p>The surprising thing is that BILINEAR and BICUBIC aren't much better. They take a formula and apply it to the 2 or 3 closest pixels to the source point, but there's still lots of pixels they don't look at, and the formula will deemphasize the line anyway.</p> <p>The best choice is ANTIALIAS, which appears to take all of the original image into consideration without throwing away any pixels. The lines will become dimmer but they won't disappear entirely; you can do an extra step to improve the contrast if necessary.</p> <p>Note that all of these methods will fall back to NEAREST if you're working with a paletted image, i.e. <code>im.mode == 'P'</code>. You must always convert to 'RGB'.</p> <pre><code>from PIL import Image im = Image.open(fn) im = im.convert('RGB') im.thumbnail(size, Image.ANTIALIAS) </code></pre> <p>Here's an example taken from the electronics.stackexchange site <a href="http://electronics.stackexchange.com/questions/5412/easiest-and-best-poe-ethernet-chip-micro-design-for-diy-interface-with-custom-ard/5418#5418">http://electronics.stackexchange.com/questions/5412/easiest-and-best-poe-ethernet-chip-micro-design-for-diy-interface-with-custom-ard/5418#5418</a></p> <p>Using the default NEAREST algorithm, which I assume is similar to the results you had:</p> <p><img src="https://i.stack.imgur.com/mcmmd.png" alt="NEAREST"></p> <p>Using the ANTIALIAS algorithm:</p> <p><img src="https://i.stack.imgur.com/zgYAx.png" alt="ANTIALIAS"></p> |

25,921,375 | 0 | <p>This is meant to complement Richard's, as it felt a little too substantial to simply edit into his.</p> <p>A typical code pattern for this sort of thing would be:</p> <pre><code>#Initialize an empty list of the desired length dfs <- vector("list",3) #Fill the list with data frames, naming as we go for (i in seq_along(dfs)){ dfs[[i]] <- data.frame(x = runif(5),y = runif(5)) names(dfs)[[i]] <- paste0("df",i) } </code></pre> <p>where the use of <code>assign</code> is typically frowned upon as bad (stylistically). If the naming of the data frames is very regular, you don't even need to do it in the loop:</p> <pre><code>names(dfs) <- paste0("df",seq_along(dfs)) </code></pre> <p>you can do it in a vectorized fashion as above. And as I mentioned below Richard's answer, even though having them all in a list is never worse, and usually better, than having them as separate objects, you can convert the list to separate objects via:</p> <pre><code>list2env(dfs,envir = .GlobalEnv) </code></pre> |
