I have two simple java codes.The first one defines constant power as power = a.pow(b); import java.math.BigInteger; public class FermatOne { public static void main(String[] args) { BigInteger a = new BigInteger ("2"); BigInteger k = new BigInteger ("15"); BigInteger c = new BigInteger ("1"); int b = 332192810; BigInteger n = new BigInteger ("2"); BigInteger power; power = a.pow(b); BigInteger exponent; exponent = k.multiply(power); BigInteger mod; mod = exponent.add(c); BigInteger result = n.modPow(exponent,mod); System.out.println("Result is ==> " + result); } } The second one defines

Android java: OutOfMemory while inserting a huge List into the database SQL

眉间皱痕 提交于 2019-12-02 05:51:48
问题 I'm just working on an Android Project where an ORM greendao is used. It allows me to insert a number of entities (which are obviously objects) into the database at once (in one transaction). In practice there's a method insertOrReplaceInTx(...) which takes as a parameter a collection, given a List of objects. The problem is that my list has sort of 12000 objects and an insert leads from time to time to an OutOfMemory Exception. I'm thinking of a smart way to solve the problem and prevent

Out of memory error with loading image

*爱你&永不变心* 提交于 2019-12-02 05:33:05
问题 I want to load an image on android background = BitmapFactory.decodeResource(getResources(),R.drawable.hangmanbegin); background = Bitmap.createScaledBitmap(background,screenx,screeny,false); The image is 800*1280 pixels , so if I'm correct it should use arround 3MB of memory space? But my heap grows from 15MB to 29MB just at that phase , so no window or context leaking? How is this explained? en what can you do about it? Thnx in advance! 回答1: Bitmaps take up a lot of memory, especially for

Before you tell me, yes I am aware that selfbots can get you banned. My selfbot is for work purposes in a server with me and three others. I'm doing nothing shady or weird over here. I'm using the following selfbot code: https://github.com/Supersebi3/Selfbot Upon logging in, being that I'm in about 50 servers, I experience the following: This carries on for several minutes, until I eventually get a MemoryError: File "main.py", line 96, in <module> bot.run(token, bot=False) File "D:\Python\Python36-32\lib\site-packages\discord\client.py", line 519, in run self.loop.run_until_complete(self.start

nodejs running out of memory processing csv files

て烟熏妆下的殇ゞ 提交于 2019-12-02 04:12:26
问题 I've read through a number of SO questions about nodejs running out of memory, but I haven't seen anything that sounds similar to my situation. I'm trying to process about 20GBs of data across 250 csv files (so ~80MBs/file). Launch the node script with --max-old-space-size=8192 on a server with 90GB of free memory using node v5.9.1. After 9mins of processing the script quits with an out-of-memory error. I'm new to Node programming, but I thought I wrote the script to process data one line at

What kind of Exceptions cannot be handled? [duplicate]

Deadly 提交于 2019-12-02 03:13:11
Possible Duplicate: List of exceptions that CAN'T be caught in .NET As is documented, try/catch blocks can't handle StackOverflowException and OutOfMemoryException. Are there any other Exceptions that also suffer from this limitation? Jeffrey Richter made several good points on this topic in his book CLR via C#, part "Trading Reliability for Productivity". BTW, you can catch and handle OutOfMemmory: For some reason that I can’t quite explain, this attention to detail is not done when writing code for the .NET Framework. Getting an out-of-memory situation is always possible and yet I almost
