| Json parse error on api call react-native Posted: 05 Oct 2021 08:21 AM PDT I have this Ajax request function. export async function fetchAllCoinsPromise() { const apiCall = await fetch('https://api.coincap.io/v2/assets'); const jsonResult = await apiCall.json(); return jsonResult; }
I call it like this: const fetchCoins = () => { fetchAllCoinsPromise() .then(res => console.log(111)) .catch(err => { console.log('err', err); fetchCoins(); }); };
the reason why I'am doing this recursion is because sometimes I'm getting this strange error: SyntaxError: JSON Parse error: Unexpected identifier "You"] and I thought the async recursion would solve the issue and it does but I am not sure if this is the best solution in case of time complexity. Any suggestions please?  |
| Function of a formula in python for big dataset Posted: 05 Oct 2021 08:21 AM PDT Say, I need to convert the following formula into python and use it on a data frame. The formula is as follows. 
The data frame has got values for Xj and Bj. The data frame looks like the following. df.head() type name OR 1 SAP1 11.21 1 SAP1 1301 2 SAP1 0.7578 2 LUF1 1447 2 LUF1 0.7578 1 ANK3 1150 1 ANK3 0.9909 1 ANK3 1535 1 ACR 0.9909 1 ACR 1535
The above data frame has got values for Xj=type and bj=OR from the data frame. I need for each sam The ^S score from the formula In the end, for each name, I need a single S score. I have implemented something like this, def score(df): df_sum =df[['type','name','OR']].groupby('name').sum().reset_index() sum =df_sum['type'] OR=df_sum['OR'] score=sum([sum*OR]) return score
The question is I need to get them for each name value single score not many scores for all repeating name values. In the end, I need only 4 rows with 4 score values. It is possible on small datasets. However, when I give a big data frame with multiple name values for OR and type columns. Then I have multiple scores for the same name  |

| Get closest match between sentence(represented as string) and list of phrases Posted: 05 Oct 2021 08:20 AM PDT Let me start with an example. Consider the following list in python cities = [ 'New york' 'San francisco', 'California', 'Las vegas', 'Chicago', 'Miami' ]
I also have following sentences. sentences = [ "Both of us were new to New York City, and had few or no friends.", "Win three more games and he becomes king of San Francisco.", "Uncurling from the couch, she started to the bedroom of her father's small Miami apartment." ]
For each sentence, find out substring in this sentence that is closest to any string present in the list. So, in this example, I want to get the longest substring for each sentence in sentences which is closest to any string in the list cities. Therefore, in this case, my result should look like: desired_result = [ 'New York', 'San Fransisco', 'Miami' ]
There are few algorithms that are in my mind, but they are not ideal. Algorithm 1 One algorithm can give very good results, but it is very bad in terms of time complexity. I tried to extract all sub phrases of a sentence, starting from n word sub-phrase to one word sub-phrase for a sentence with n tokens. Then I use difflib.get_close_matches function to detect any sub-phrase that is closest to any string in the list of cities. However, the complexity as we can clearly see is very high. For sentence of length n, we have total O(n*n) sub-phrases. Also, the list of cities is not small. In my real-world use-case this list contains around 7 million strings. In this case, my code looks like this: def generate_subphrases(sen): subphrases: List[str] = [] # My logic to generate all possible subphrases # . # . # . return subphrases result = [] for sen in sentences: subphrases = generate_subphrases(sen) ans = None for phrase in subphrases: if get_close_matches(phrase, cities): ans = phrase break result.append(ans) print(result)
Algorithm 2 This is bit faster compared to previous approach, however, this is not as good as last one. The benefit of using last approach was that we could tolerate few mismatches in that approach. For example, New York would be detected if the cities list even contained New york. However, in this case we do not tolerate even single character mismatch. In my use-case, I can tolerate error upto 30-35% in terms of character mismatch. In this approach, I form huge regular expression with union of all cities in the list. Then I use re.search to search for the sub-phrase in my sentence. In my opinion, this is faster but not very good. I want to know if I can use any data structure to achieve this task, or any python utility function similar to difflib.get_close_matches that can allow searching over entire sentence.  |

| Returning an Object's method names Posted: 05 Oct 2021 08:20 AM PDT I have the ability to run code that lets me make calculations and/or get variable information from a program. However I do not have access to the base code, and wondering if there is a way to print out all the methods an Object has available (public)? Example the Class Shape, with sub classes of Circle and Square. If I was able to print out methods to Circle I would possibly see: .getRadius() .setRadius(newValue)
but Square would have .getSide() .setSide(newValue)
I have a myObject, where I know I can get myObject[1].GetLength() myObject[1].getDimUom() myObject[1].getQuantity().getValue()
However I am unaware of what I can set only certain things like (by trial and error) myObject[1].setClass(newValue)
So I would like to be able to find a way to print out the method names from an Object; again without any ability to see or modify base code (like adding reflection)  |

| How to add echo effect to wav file in android? Posted: 05 Oct 2021 08:20 AM PDT I have been struggling for a while now on how to modify a wav file by adding echo effect on it; My app does pitch sifting, speed and volume, but I can't add effects. I'm a total begginer at audio engineering or something like that. My main goal is to find an algorithm and make a function that takes the byte[] samples and modifies it. I'm using this current code right now: sonic = new Sonic(44100, 1); byte samples[] = new byte[4096]; byte modifiedSamples[] = new byte[2048]; int bytesRead; if (soundFile != null) { sonic.setSpeed(params[0]); sonic.setVolume(params[1]); sonic.setPitch(params[2]); do { try { bytesRead = soundFile.read(samples, 0, samples.length); } catch (IOException e) { e.printStackTrace(); return null; } if (bytesRead > 0) { sonic.putBytes(samples, bytesRead); } else { sonic.flush(); } int available = sonic.availableBytes(); if (available > 0) { if (modifiedSamples.length < available) { modifiedSamples = new byte[available * 2]; } sonic.receiveBytes(modifiedSamples, available); if (thread.getTrack() != null && thread.getTrack().getState() != AudioTrack.STATE_UNINITIALIZED) thread.WriteTrack(modifiedSamples, available); } } while (bytesRead > 0);
As you can see I use sonic ndk to alter the pitch speed and volume by passing another byte[] array there "modifiedSamples" and I need to know if there is a way to modify this "modifiedSamples" to get the echo effect. I know this sounds like I'm asking for the function, but I don't. I just don't know anything about audio processing stuff and I would apreciate a starting point or even if what i'm trying to do is possible with my byte array.  |
| How to measure elapsed time in Python? Posted: 05 Oct 2021 08:21 AM PDT What I want is to start counting time somewhere in my code and then get the passed time, to measure the time it took to execute few function. I think I'm using the timeit module wrong, but the docs are just confusing for me. import timeit start = timeit.timeit() print("hello") end = timeit.timeit() print(end - start)

| autocomplete in vaadin? Posted: 05 Oct 2021 08:21 AM PDT I'm new to vaadin. How do I do autocomplete (actually, more like google suggest) on a huge set of data that cannot be loaded in memory, but instead performing a JPA query on every key event. Is it possible to capture key events on a textfield or combobox?  |
