@Aura09c what kind of challenge?
How many bytes make 1 KB? is it 1000 or 1024? as far as i learned it is 1024 bytes. Getting mixed results on the internet so confusing . What is the right answer?
Julian Gonggrijp
@Srinath-V-S The kB traditionally used to mean 2^10 bytes, but in recent years, people have reverted to using the "kilo" prefix exclusively in the SI meaning, i.e., a factor of 10^3. There is now a new prefix ki ("kibi") for 2^10 so you can be more explicit about what you mean. Likewise, Mi for 2^20, Gi for 2^30, and so on.

Hi, I use Python on a school chromebook (because I'm not at home and my phone is incredibly laggy) and I want to know if there are any Python coding applications that you can download without linux? (I can't use linux.)
Julian Gonggrijp
@Jonah31162987_twitter since you write that you are already using Python, what exactly do you mean by a Python coding application? What are you trying to achieve?
Hi. I'm creating a tool like diff-checker. I use codemirror library for that. They provide a addon called merge/merge.js which basically has all the functions that i needed for diff check tool. However when i add that file in my project and use one of its constructor CodeMirror.MergeView, I'm getting Uncaught TypeError: CodeMirror.MergeView is not a function this error. Please help me what i'm doing wrong?.
Julian Gonggrijp
@Srinath-V-S Could you post a link to your code? Without seeing your code it's going to be blind-guessing.

how to create custom public ethereum address starting with say '0xajc'
Just confirming I m here


var value, orig1, orig2, dv, panes = 2,
    highlight = true,
    connect = null,
    collapse = false;

function initUI() {
    var target = document.getElementById("view");
    target.innerHTML = "";
    let dv = CodeMirror.MergeView(target, {
        value: value,
        origLeft: panes == 3 ? orig1 : null,
        orig: orig2,
        lineNumbers: true,
        mode: "",
        highlightDifferences: highlight,
        connect: connect,
        collapseIdentical: collapse


I thought once its constructor is initialized i'll get two panes in the UI but getting that error mentioned above.

Julian Gonggrijp
@Srinath-V-S Is this the whole script? There is no header with import or require statements? Do you have <script src="..."></script> lines somewhere in your HTML that will import codemirror and the merge extension?

Hello, does anyone why is the CSS Grid acting abnormally on this page (here). The relevant CSS classes used are grid grid-cols-7. I have been using multiple methods(float and flex) to properly render and align the divs, but can't seem to make them work the way it should be. Any insight into what is happening here will be helpful.

Hi. This might be a silly thing to ask, but I need help in understanding how 'sed' commands work. Like what is the difference between

sed -i -e "s/# tlsProvider=.*/tlsProvider=OpenSSL/" apache-pulsar-2.7.2/conf/bookkeeper.conf


sed -i -e "s/tlsProvider=.*/tlsProvider=OpenSSL/" apache-pulsar-2.7.2/conf/bookkeeper.conf

Whats with the 's/#' and the 's/' ?

Julian Gonggrijp
@SauravDeb No idea. Maybe you can search the sed man page for the # character?
