counter

I am trying to get timestamp to show- I have tried the onCreate query in different ways and also tried to to have addTime as a value in addPrime . Nothing seems to work. My intention is for the app to show previous primes and the time that they were found. The intention for the app is for the user to be able to close/kill the app and resume counting from last found prime number when restarting the app, if you have any hints how also this would be possible I would be grateful. This is the PrimeDBManager class public class PrimeDBManager extends SQLiteOpenHelper { private static final int

I'm creating new threads for every sql call for a project. There are millions of sql calls so I'm calling a procedure in a new thread to handle the sql calls. In doing so, I wanted to increment and decrement a counter so that I know when these threads have completed the sql query. To my amazement the output shows NEGATIVE values in the counter. HOW? When I am starting with 0 and adding 1 at the beginning of the process and subtracting 1 at the end of the process? This int is not called anywhere else in the program.. the following is the code.. public static int counter=0; while(!txtstream

I needed to generate an output from my Access database that was unavailable using standard functions. I did extensive searching, but when I found example code - it ultimately failed. So, I started from scratch, pulling from others' work where possible. The code below is probably very primitive, but it works for me and the operation in the database. What I'd really like to see is how this code could be made more compact and efficient. I'm not dealing with many lines today (<20), but I could in the future. The data: a b b b c c d The desired result: a, 1 b, 2 b, 2 b, 2 c, 3 c, 3 d, 4 Can anyone

I have the following code to count visitors on my PHP site. It works fine on my local development machine using WampServer but when I uploaded my files to my hosting account for testing I realized that it does not work properly. I get really high number count and also noticed the session are never deleted so they just keep accumulating. It is a simple session counter. Is there a better way of doing it? Could some one please show me or point me to some article? Thank you! <?php //------------------------------------------------------------ // VISITORS ONLINE COUNTER //--------------------------

I'm new to sparql and trying to fegure out what is the best way to select the max value of a counter of another query without creating a new table, only using sub-queries. I'm working on a relatively small dataset so the computation time is not a problem. SELECT ?p1 ?c1 (MAX(?cnt1) AS ?maxc) WHERE{ { SELECT ?p1 ?c1 (COUNT(?s1) AS ?cnt1) WHERE { ?s1 ?p1 ?o1; a ?c1. }Group by ?p1 ?c1 #ORDER BY ?p1 DESC(?cnt1) } }GROUP BY ?p1 so I'm expecting to get a row for every value of ?p1 with the max ?cnt1 the suitable ?c1 I'm pretty sure that is the way to do that but for some reason it causes my endpoint

PROBLEM: Write a C program that prompts the user to enter a string of characters terminated by ENTER key (i.e. ‘\n’) and then count the total number of the occurrence of each vowel in the string. Your program should use the following guidelines: • Your program should declare an array of 5 integer counters, namely counter. • Using a loop, your program should initialize each member of the array to 0. • Each character in the string is then checked to see if it is a vowel, i.e. ‘a’, ‘e’, ‘i’, ‘o’ or ‘u’. In that case, the corresponding counter is incremented. For example if an ‘a’ is read then

In Hadoop we can increment counter in map/reduce task, it looks like this: ... context.getCounter(MyCountersEnum.SomeCounter).increment(1); ... Than you can find their value in log. How do you access them from code after job completes? What is Hadoop API to read counter value? Counters represent global counters , defined either by the Map-Reduce framework or applications. Each Counter can be of any Enum type. You can define counter as an enum in Driver class static enum UpdateCount{ CNT } And then increment the counter in map/reduce task public class CntReducer extends Reducer<IntWritable,

What's the best way (in terms of readability and efficiency) of finding the union of a list of Counters ? For example, my list might look like this: counters = [Counter({'a': 6, 'b': 3, 'c': 1}), Counter({'a': 2, 'b': 5}), Counter({'a': 4, 'b': 4}), ...] I want to calculate the union, i.e. counters[0] | counters[1] | counters[2] | ... . One way of doing it would be this: def counter_union(iterable): return functools.reduce(operator.or_, iterable, Counter()) Is there a better approach? Goodness, when did Python programmers become afraid of easy loops? LOL. result = Counter() for c in counters:
