pipe/stream gnupg output to tarfile in

由 限于喜欢 提交于 2021-02-05 09:37:32
问题 I have the following code but obviously this is not real streaming. It is the best I could find but it reads the whole input file into memory first. I want to stream it to tarfile module without using all my memory when decrypting huge (>100Gb files) import tarfile, gnupg gpg = gnupg.GPG(gnupghome='C:/Users/niels/.gnupg') with open('103330-013.tar.gpg', 'r') as input_file: decrypted_data = gpg.decrypt(input_file.read(), passphrase='aaa') # decrypted_data.data contains the data decrypted

Stream 2d array, trim values and collect back to 2d array

由 怎甘沉沦 提交于 2021-02-04 21:16:26
问题 Any idea how to perform a trim operation on a 2d array of strings e.g. 3x3 using Java stream API and collect one back to same dimension 3x3 array? The point is to avoid using explicit for loops. The current solution would be simply to do a for loop like: String arr[][] = { {" word ", " word "}, {" word ", " word "}, {" word ", " word "}}; for (int i = 0; i < arr.length; i++) { for (int j = 0; j < arr[i].length; j++) { arr[i][j] = arr[i][j].trim(); } } And that works, but I'm trying to come up

Cant send minecraft login packet to server?

问题 Minecraft is a game which also can be played on multiplayer servers. Each server has its own IP and the port is for every server "25565". In generell, for this problem you should be familiar with Minecaft protocol(https://wiki.vg/Protocol#Login_Start). Even if not, I created a hyperlink where you can look for this. My goal is to create a Minecraft Chatbot, without even open Minecraftlauncher to join any server. I know, there are already a lot of these existing, but I want to create some new
