Définition du KPI
Il s'agit d'un acronyme de Key Performance Indicator, ce qui signifie en français : Indicateur de performance clé.
Ce sont des mesures qui permettent aux entreprises d'évaluer la performance d'un domaine. On parle aussi de "metrics", même si une différence existe entre ces 2 termes :
les KPIs sont liés à un objectif … Read More →

À l'informatique
Von Neumann a donné son nom à l'architecture de von Neumann utilisée dans la quasi-totalité des ordinateurs modernes, l'apport d'autres collaborateurs de l'EDVAC en est par conséquent grandement minimisé (on citera J. Presper Eckert et John William Mauchly parmi d'autres). Cela est dû au fait qu'il est, en 1945, le rapporteur des travaux pionniers … Read More →
Write a function to find the 2nd largest element in a binary search tree
Here's a sample binary tree node class:
Gotchas
Our first thought might be to do an in-order traversal of the BST and return the second-to-last item. This means looking at every node … Read More →
Let’s explore recursion by writing a function to generate the terms of the Fibonacci sequence. We will use a technique called “memoization” to make the function fast.
We’ll first implement our own caching, but then we will use Python’s builtin memoization tool: the lru_cache decorator.
An algorithm is little more than a series of steps required to perform some task. If we treat each step as a basic unit of computation, then an algorithm’s execution time can be expressed as the number of steps required to solve the problem.
This abstraction is exactly what we need: it characterizes an algorithm’s efficiency … Read More →
Data warehousing provides decision-support data that is consistent, integrated, standard, and simply understood.
What Is Data Warehousing ?
Data warehousing is a process for collecting, storing, and delivering decision-support data for some or all of an enterprise. Data warehousing is a broad subject that is described point-by-point in this Refcard. A data warehouse is one of the … Read More →

This book is a practical—and, we hope, entertaining—introduction to some of the most important algorithms and data structures in computer science.
We know that some software engineers think “practical algorithms” is an oxymoron 😞 so we’ve done our best to keep this book brief, useful and approachable.1 The code samples are in idiomatic Python, and the … Read More →
Problem
Write a function kth_to_last_node() that takes an integer kand the head_node of a singly-linked list, and returns the k-th to last node in the list.
Linked Lists
In computer science, a linked list is a linear collection of data elements, whose order is not given by their physical placement in memory. Instead, each element points to the … Read More →

Let's say:
'(', '{', '[' are called "openers."
')', '}', ']' are called "closers."
Write an efficient function that tells us whether or not an input string's openers and closers are properly nested.
Examples:
"{ [ ] ( ) }" should return True
"{ [ ( ] ) }" should return False
"{ [ }" should return False
Solution
We iterate through our string, … Read More →

DOTNET exposes several ways to achieve mutual exclusion in code such as Mutex, Lock, SynLock, Manual reset event or Thread wait etc. The same thing can be achieved even in SQL Server using application locks. It is achieved by using 2 system stored procs (sp_getapplock and sp_releaseapplock)
Permissions:
However to be able to call sp_getapplock a user … Read More →
LOCK_TIMEOUT is not only a session-level setting, it also needs to be set in a separate batch. But, it cannot be set via a variable. So, this can be accomplished by using Dynamic SQL in the "master" Stored Procedure. This will allow for setting LOCK_TIMEOUT and then executing whatever other Stored Procedure that should run … Read More →
