How can I make my function better and favor functional programming style?
On this single-page site I have a fixed navigation list. Each item in the list has a transparent background and I have a #nav-highlight div that I move with JavaScript and animate with CSS for an interesting effect while s...
Original code and demo at this gist.
Given a Markdown document like
Here is some text,

```javascript

More text follows, and then
```javascript
console.log(message);

This is the same problem as the Python task scheduler, but in Go.
I chose not to use a sync.Cond (I couldn't seem to get that right), but instead use channels.
var (
mu sync.Mutex
ts tasks
ch chan bool
)
func init() {
ch = make(chan bool)
ts = make([]*Task, 0)
heap.Init(&...
I have a Parent and a Child class, each with their own state. The Parent maintains an array of children saving their values from their state.
React 101 says that I should lift the state up from the child and set the array from there. There's also this question that asks how to access child's sta...

I have a google form with multiple choice questions (of both types), like this one
How can I fill those questions using python mechanize?
I even couldn't find the name of the buttons to try to do this, and br.form doesn't contain anything about the buttons.
This is the code that I have right no...
I have a tree structure where at every node there is a list of documents (document length can vary from 5 to 500), and each document contains a number of words. I want to calculate relative frequency of each word at a particular node by taking the ratio between the percentage of time that word ap...
I created an example of a simple form for a last name input in React, where I can check the validation of the data at the time of input.
The last name should contain only small and capital letters, numbers, special characters, etc. If the user enters other characters, the error text is displayed....
This is a simple 2D rendering abstraction that I've been using for my game. It's basically a vector of quads. It has functions for pushing quads onto the vector and a function to render the quads using the OpenGL rendering abstraction. I had to comment out the render function because it depends o...
The following is a summary from the top of my head so please correct me if I'm wrong. See the Wikipedia article for more.
This is about determining the (score / edit distance of the) most similar substrings of two given strings.
For example, given the two sequences

GGTTGACTA

I learned a lot of different examples of the form validation using React and I don't understand where is the better ...
Design review or code review?
Well, in real-world projects we communicate the design in its own way first, not just say “here’s code that implements my design.” I would like to see a paragraph explaining how it works in very simple overview, and a sketch showing the different types and their re...
Back when I was a full-time programmer and there was some code someone struggled with, it was a common practice to ask around in cubicle land. Sometimes you’d get lucky and find someone who know the answer right away or knew where to look in the documentation. When Stack Overflow launched, I cultivated a habit of asking and immediately answering questions I’d heard discussed at the office on the site. To this day, I get upvotes on questions like “How can you untar more than one file at a time?” It doesn’t just add to my reputation score—it also feels great to know I’ve helped dozens¹ of strangers. How often can you say that about an hour or so of effort? …
I'm building a calendar hour per hour for a festival (5day) where there is shows every 30 minutes and sometimes at the same time. I build this code that works very well but he is very loud to load on the page, approximatively 3000 lines of php and 100 query to work !

What I'm trying to achieve is the following:
Given a Map, where the values may contain duplicates, I want to change the values so that they are incrementing by 1, starting from 1.
Example:
{"One"=1, "Three"=3, "Another three"=3, "Seven"=7} should result in:
{"One"=1, "Three"=2, "Another three"...
Got this sample code from a cheatsheet for ES6 explaining Javascript pipeline.
const pipe = functions => data => {
return functions.reduce(

data
);
};

const addSalesTax = (total, taxRate) => (total * taxRate) + total;

So I want to ping some devices in my network, the way I want to do it is, have the ip being shown with a green background being that the ping return OK, if it times out I want it to be changed red. I was able to do it on Tkinter but I cant figure out how to do it on PyQt.

I did not move forward in this interview process, because another applicant did better than me, which wasn't surprising given that this was my first foray into Node.js.
I'd like some tips on how I could have made this a better submission, and also more generally I'd like to know how I could do t...

I am having a hard time implementing/using an ordinal classification cost function for my Convolutional Neural Network in Tensorflow.
Any implementations/documentation/repository on that which you know of?
Providing a link at GitHub, just in case.
Made solely for educational purposes (initially the hometask was to implement a simple struct with defined +, - operations defined on binary). Templated class (power must be a power of two) which allows to store an integer as binary representation, where...
