Dynamic Programming Problems: Learn to Solve Them More Efficiently

DZone

Programming is all about solving issues and problems. There is an end number of programming issues that the developers face when they are writing code for developing a website, applications, or any other type of software. Programming problems can be listed and are sorted based on various categories of programming languages used like PHP, Java, Python, C++, and many others, which developers use for coding.

Java vs. Python Comparison: The Battle of Best Programming Language in 2021

Comparing two programming languages is similar to a comparison between two cars, where two different individuals may have different opinions on both of them. Well, as starters, computer programming languages have come a long way since their inception. Today, everything we dwell upon has to have a programming language behind it, easing away our troubles. java python performance programming language python development python developer java developers

Rethinking Programming: Automated Observability

DZone

Introduction. Observability is the ability to understand the internal state of your system by looking at what is happening externally. In a software system, in order to acquire observability, we mainly implement the following aspects: logging, metrics, and tracing. Especially when we are moving away from monolithic software systems to microservices-based architectures, observability becomes a key aspect of the system design.

The True Hardest Programming Problem Is Tight vs. Weak Coupling

A few months ago, I claimed that naming is the hardest programming problem. The true hardest problem is one that impacts every developer at every skill level, across all programming languages, regardless of experience. It is equally applicable across all programming disciplines. The hardest problem in programming is this: performance tight coupling weak couplingI was wrong.

Do Programming Languages Matter?

Professor Beekums

A lot of attention is given to programming languages. Does it really matter what programming languages you know though? Many companies list positions such as “PHP Developer” or “Java Programmer”. Those interested in learning how to code often ask what language they should learn. Developers themselves argue over the merits of various languages. There are a growing number of people, including myself, that don’t take known languages into account when hiring

Parallel programming in Python: multiprocessing (part 1)

PDC

Parallel programming solves big numerical problems by dividing them into smaller sub-tasks, and hence reduces the overall computational time on multi-processor and/or multi-core machines. Parallel programming is well supported in traditional programming languages like C and FORTRAN, which are suitable for “heavy-duty” computational tasks. In serial programming we can use the following code to compute and print the result, via list comprehension.

Parallel programming in Python: mpi4py (part 1)

PDC

In previous posts we have introduced the multiprocessing module which makes it possible to parallelize Python programs on shared memory systems. This module provides an object-oriented interface that resembles the message passing interface (MPI) , and hence allows Python programs to exploit multiple processors on multiple compute nodes. Now we can write our first Python program with mpi4py.

Parallel programming in Python: mpi4py (part 2)

PDC

In part 1 of this post , we introduced the mpi4py module (MPI for Python) which provides an object-oriented interface for Python resembling the message passing interface (MPI) and enables Python programs to exploit multiple processors on multiple compute nodes. As we mentioned in part 1 of this post , collective communication methods are very useful in parallel programming.

Parallel programming in Python: multiprocessing (part 2)

PDC

In the previous post we introduced the Pool class of the multiprocessing module. In this post we continue on and introduce the Process class , which makes it possible to have direct control over individual processes. A process can be created by providing a target function and its input arguments to the Process constructor. The process can then be started with the start method and ended using the join method. Below is a very simple example that prints the square of a number.
