I'm generating a lot of to-be reused SQL. A question on the visibility of aliases in SQL. If I create a query as followed:
SELECT name, age
FROM tablea a
JOIN
(SELECT pid, age
FROM tablea a
JOIN tableb b ON a.pid = b.pid) tage ON a.pid = tage.pid
Would this generate any issues?...
I've written an full adder in haskell.
xor :: Bool -> Bool -> Bool
xor a b = (not (a && b)) || not (not a && not b)
fulladder :: Bool -> Bool -> Bool -> (Bool -> Bool)
fulladder a b c = (xor (xor a b) c) ((a && b) || (c && (xor a b)))
but ghci tells me that I would try to apply xor to to thre...
I have created an observable to emit single item or emit an error and stop.
Is this a correct way to create single Rx Event in Typescript ?

This simple piece of software is generating a vehicle object by using the get_vehicle() function,
Whenever i need to generate a specific vehicle I pass in the vehicle ID to this method and it returns the appropriate vehicle.
Within the get_vehicle() function, each vehicle is generated within ...
My idea is to not not expose/use service's Proxy everywhere throughout the application, rather exercising all service communications(using client Proxy) from a single class. To achieve this I have created below class: -

A factorial of a number is the product of all the integers from 1 to that number. For example, the factorial of 5 (denoted as 5!) is 1*2*3*4*5 = 120.The factorial of 0 is 1.
Here is my code:
def recur_factorial(x):
if x == 1:
return 1
else:
return (x * recur_factorial(x...
I'm trying to execute function after function but I want that p2() and p3() start even if p1() reject.
How can I improve this ?

alert(val2);
this.p3().then((val3) => {

I'd like to parse a MIDI file and simply extract every Note On event and then write that information to a text file. (This is a MIDI file which I export from the piano-roll in my DAW by the way)
So the text outputfile would output the following for example:
D1, C2, D2, E4
... etc
These repres...
I have written a Python program to take in two strings and print the larger of the two strings.
Here is my code:
string1 = input("Enter first string: ")
string2 = input("Enter second string: ")
count1 = 0
count2 = 0
for i in string1:
count1 = count1 + 1
for j in string2:
count2 = c...
I'm hoping someone would be able to identify if my code is prone to SQL injections, and just overall see if there is anything that could be done better, faster or more efficiently
Im very new to OOP and prepared statements so there might be some glaringly obvious problems but just let me know!

I wrote code sample below that is finding decimal values in jObject without '.' char, and convert them to long type. The issue is, that it looks really ugly, and it works for max jObject that contains two child jObjects. Any ideas?

I wanted to create a simple LinkedList implementation in PowerShell in preparation of a SkipList implementation. This LinkedList currently starts and ends with a Null node, and when items are inserted, they are inserted in increasing order.
For example, adding 217, 436, and then 178 into the lis...
Problem:
A and B decide to duel but, being poor, they have just one gun (a six-shot revolver) and only one bullet. Being dumb, as well, this does not deter them and they agree to "duel" as follows: They will insert the lone bullet into the gun's cylinder, A will then spin the cylinder and shoot ...
This function is supposed to find words starting with a given prefix in a container. The container is sorted. This function is a fairly performance-critical part of the code, so I am open for any optimization suggestions.

I'm trying to find a hash collision of my modified hash function. Assuming my modified hash only outputs the first 36 bits of SHA-1. As we know, SHA-1 is a 160-bit hash value, hence, we only need to output 9 characters out of 40 characters for comparison.
How i begin my program is by hashing a ...
