This is a rags-to-riches attempt from this question, based on the popular 99 Bottles of Beer, by (lightly) using Java 8's stream-based processing.
Any room for improvement in terms of readability? I can only think of two concerns:
It's not immediately obvious what the placeholders for each Lin...
I have multiple parts based on the same length. If the assembly is 400mm wide, part1 is 200mm, part2 is 180mm and part 3 is 150mm. It would be great if I could declare the length of those parts as (respectively) al-200, al-220 and al-250 (where al is the length of the assembly).
Can I store this...
Try to use spring-batch. It's more sutable for bulk load
I'm developing a web application for simulating electronic circuits and I'm trying to add backward propagation options (guess you can immagine why). During refactoring I came up with a base class for logic operations and wanted to ask for some feedback (whatever pops up in your mind) on it. The c...
I made this way to create classes in javascript.
is it the correct way to create Classes in Javascript?
What do you think about this?
function Client(firstName, lastName) {
var _public = this, _private = {};
_public.firstName;
_public.lastName;
_private.constructor = function() {

Having read Effective Java and Clean Code I wanted to apply these principles in a manageable scenario. To this end I refactored a java library that calculates similarities between strings.
The code below is that of a cosine metric. Documents are tokenized into multisets of strings. These are pa...

Falling through switch-cases can be achieved by having no code in a case (see case 0), or using the special goto case (see case 1) or goto default (see case 2) forms:
switch (/*...*/) {
case 0: // shares the exact same code as case 1
case 1...
I wanted to write a function findDeep that would perform a recursive, depth-first search on plain objects and arrays.
Comments and criticism welcome.
function findDeep(dict, test, index = 0, keys = Object.keys(dict)) {
var item = dict[keys[index]];
if (item === undefin...
A colleague of mine sent me an interesting question, that I can't entirely explain.
He ran some code (included below) and got somewhat unexpected results from it.
Essentially, when converting a UniqueIdentifier (which I'll refer to as Guid from here on out) to a binary (or varbinary) type, the ...

According to the Wikipedia article on Globally unique identifier (in the "Binary encoding" section), Microsoft's implementation of GUIDs uses "Native" endianness for the first half (the first 8 bytes), and Big Endian encoding for the second 8 bytes. Microsoft Windows and SQL Server are "Little En...
I'm developing backend for my mobile app by using gin-gonic and gorm ORM (mysql). But I'm not sure api and db handle huge amount requests if clients increased. for example I'm using my db struct as parameter, is this a problem for concurrency ?

Relatively new to rails and would like your thoughts on how to best model data for my practice app.
App will allow users to login and upload a CSV file that contains temperature data from a device. This data will be stored and the user can view all these downloads and select one from a list to v...
Do not use (if possible) static classes. You save few bytes and few CPU cycles but they're harder to test if you need to mock their implementation. It's a general rule then it may allow exceptions (not in this case, IMO).
Do not return Func<LogicValue, LogicValue, LogicValue[][], int, LogicValue>...

Is there anyone who can help me improve the time complexity of this back pack algorithm, for which I have already use sliding array to improve the space complexity.
The problem is as follows:
Given n items with size A[i], an integer m denotes the size of a backpack. How full you can fill this ...
Below is the problem statement , I have applied Dp , getting TLE in most cases . How to do it faster? I am also eager to know whether there is any other method to memoize because this type of grid problems are most asked more often .
