Vote count: 0 I have a domain name registered on namecheap. Let's say it is mysite.com. I want this domain to be my personal site. I also want to create a subdomain like myapp.mysite.com for a Rails app on Heroku. I have tried to configure one in the DNS section of the Namecheap dashboard but I'm new with theses things. I'm using a CNAME type, @ for host and automatic for TTL. I have also added myapp.mysite.com as a custom domain in my Heroku dashboard. Am I doing this right? Please explain it in detail so I can lea more about DNS. asked 2 mins agoFrank Noel Let's block ads! بخوانید, ...ادامه مطلب

Vote count: 0 I am currently leaing data structure and trying to implement a BST and max-heap(use BST as base class). But I accidentally found it seems impossible to derive heap from BST. Almost all the implementation for heap are based on array rather then using pointers point to left and right, and most of BST are based on pointers rather than array. So my question is why I have to use array to realize a heap? And, in realizing BST, why people choose to use pointers point to left and right rather array? I know use array to realize BST may cost more space, and it is harder to implement remove function, is there any more reason for that?

Vote count: 0 I've built a custom NSURLProtocol which is used by a WebView whilst it browses. But at seemingly random times (between a 20 seconds or a few minutes into browsing) I am getting an EXC_BREAKPOINT and the app stops running in my NSURLProtocol. The relevant part of my NSURLProtocol is below, it's the last line which is showing the EXC_BREAKPOINT self.mutableData = NSMutableData(data: data!) self.response = response self.client?.URLProtocol(self, didReceiveResponse: response!, cacheStoragePolicy: NSURLCacheStoragePolicy.Allowed) self.client?.URLProtocol(self, didLoadData: data!) self.client?.URLProtocolDidFinishLoading(self) The Xcode error is visible below: I'm totally bamboozled on this one. Does anyone have an idea what might be causing this, and how to fix it? Thank you! Sam asked 1 min agoSam Heather Let's block ads! بخوانید, ...ادامه مطلب

Vote count: 0 In python there's a built-in heapq algorithm that gives you push, pop, nlargest, nsmallest... etc that you can apply to lists. However, there's also the queue.PriorityQueue class that seems to support more or less the same functionality. What's the difference, and when would you use one over the other? asked 2 mins agoYasser 1 Answer Vote count: 0 Queue.PriorityQueue is a thread-safe class, while collections.heapq makes no thread-safety guarantees. From the Queue module documentation: The Queue module implements multi-producer, multi-consumer queues. It is especially useful in threaded programming when information must be exchanged safely between multiple threads. The Queue class in this module implements all the required locking semantics. It depends on the availability of thread support in Python; see the threading module. answered 1 min agoMartijn Pieters♦ Let's block ads! بخوانید, ...ادامه مطلب

Vote count: 0 As the title says, i have a game that plays a MIDI file in the background. This appears to create millions of instances of com.sun.media.sound.ModelSource[], taking up lots of RAM, causing GC lag spikes and probably clearing some SoftReferences (i'm not sure if they does). I don't have any other sound related code and it also does not appear to be related to the size of the soundbank I use. Is there any way to improve the memory footprint? My code: public class MusicPlayer { private Sequencer player; private Synthesizer synth; private Soundbank bank; private boolean paused = false; private boolean ready = false; public MusicPlayer() { try { // Initialize MIDI output player = MidiSystem.getSequencer(false); synth = MidiSystem.getSynthesizer(); bank = MidiSystem.getSoundbank(new BufferedInputStream(getClass().getResourceAsStream("path/to/soundbank.sf2"))); player.open(); synth.open(); player.getTransmitter().setReceiver(synth.getReceiver()); synth.loadAllInstruments(bank); } catch (Exception e) { System.err.println("MUSIC INITIALIZATION ERROR: n" + e.toString()); } } /** * Starts playing a new track */ public void play(String name) { try { Sequence track = Loader.getSong(name); player.stop(); player.setSequence(track); player.setMicrosecondPosition(0); // Rewind if needed player.setLoopCount(Sequencer.LOOP_CONTINUOUSLY); paused = false; ready = true; player.start(); // And here we go! } catch (Exception e) { System.err.println("MUSIC PLAY ERROR: n" + e.toString()); retu; } } /** * Pauses the currently playing track */ public void pause() { if (!paused && ready) { player.stop(); , ...ادامه مطلب

Vote count: 0 I'm trying to run the NLP and openNLP packages in R with rJava, and I keep getting a similar error: Java.lang.OutOfMemoryError: Java heap space. I've already tried: options( java.parameters = "-Xmx4g" ) library( "RWeka" ) I've also tried increasing to 8g. Still running out of space, still crashing R. I'm working on annotating a .txt file-- a large one, yes, but just one file. Trying to extract location names. Any ideas how I can fix this issue?

Vote count: 0 I build a sensor unit where data are gathered at one Raspberry Pi and send to another's over the network. My first Pi creates a line with multiple readings from different sensors. It supposed to create a server and send it to clients. The client Pis needs to receive the sentence, do further processing or visualisation. To test my solutions I want to read data from a txt file, which was build in an experiment. The problem is that sometimes data are corrupted, has different format depending on sensor and rows can be different for different set-ups. I have build a function which suppose to change the input line to bytes. (I tried different methods but only this clunky function is the closest to any results). But it does not convert over the network import struct message = ['First sensor', 'second data', 'third',1, '19.04.2016', 0.1] def packerForNet(message): patte = '' newMessage = [] for cell in message: if isinstance( cell, int ): patte += ('I') newMessage.append(cell) elif isinstance( cell, float ): patte += ('d') newMessage.append(cell) elif isinstance(cell, str): patte += (str(len(cell))) patte += ('s') newMessage.append(cell.encode('UTF-8')) else: cell = str(cell) patte += (len(cell)) patte += ('s') newMessage.append(cell.encode('UTF-8')) retu (newMessage, patte) newMessage, patte = packerForNet(message) patteStruct = struct.Struct(patte) packedM = patteStruct.pack(*newMessage) The output from the function does not unpack correctly: packedM = b'First sensorsecond datathirdx01x00x00x0019.04.2016x00x00x00x00x00x00x9ax99x99x99x99x99xb9?' 56 print('unpacked = %s' % patteStruct.unpack(packedM)) TypeError: not all arguments converted during string formatting In addition I need to know the patte to unpack it on the client side so in general , ...ادامه مطلب

Vote count: 0 Hey so I recently created an Android application that basically connects to an access point and if it isn't in range, it uses peer-to-peer connectivity to reach other devices that are in range of the AP themselves. Mistakenly, I hard coded the wrong SSID and as a result, if I go into my WiFi settings and take a look at my saved networks, there it is. The obvious solution would be to simply remove it by tapping on it and selecting 'Forget' but every so often, it appears on the list again. I've tried clearing the entire configuration file both manually and programmatically but it still somehow makes it's way on there. And this isn't just a pet peeve, I think it's somehow related to my actual problem, why I'm always having trouble connecting to secured networks anywhere I go. I have to reenter the credentials every time and its become a bit of a hassle. I've searched the inteet and the solution seems to be deleting the corrupted config file: '/data/misc/wifi/wpa_supplicant.conf' or a path that's similar. After trying the ADB tool, I don't believe I even have read access as I kept getting a 'No such file or directory' error. My device isn't rooted and all signs point to going in that direction but if I were to go through all that trouble I might as well just factory reset my phone and have everything go back to normal. Any last minute ideas before I break the glass and push the red button?
