  37 powerful Linux shell commands

To work on Linux platform, you cannot avoid using shell commands to complete some tasks. These tasks can be as simple as list files in some directories or find some text in some file, or can be as complex as monitoring processes. In this post, we will share 37 powerful Linux shell commands.   Task Commands 1 Delete file with 0 byte(empty file) find . -type f -size 0 -exec rm -rf {} \;find . type f -size 0 -delete 2 Check process memory consumption ps -e -o "%C : %p : %z : %a"|sort -k...

  Make Big Data Collection Efficient with Hadoop Architecture and Design Tools

Hadoop architecture and design is popular to spread small array of code to large number of computers. That is why big data collection can be made more efficient with hadoop architecture and design. Hadoop is an open source system where you are free to make changes and design new tools according to your business requirement.   Here we will discuss most popular tools under the category Hadoop development and how they are helpful for big projects. Ambari and Hive– When you are designing...

  Lasagna Code

Anyone who claims to be even remotely versed in computer science knows what “spaghetti code” is. That type of code still sadly exists. But today we also have, for lack of a better term — and sticking to the pasta metaphor — “lasagna code”.Lasagna Code is layer upon layer of abstractions, objects and other meaningless misdirections that result in bloated, hard to maintain code all in the name of “clarity”. It drives me nuts to see how badly some c...

  The ugliest C feature:

<tgmath.h> is a header provided by the standard C library, introduced in C99 to allow easier porting of Fortran numerical software to C. Fortran, unlike C, provides “intrinsic functions”, which are a part of the language and behave more like operators. While ordinary (“external”) functions behave similarly to C functions with respect to types (the types of arguments and parameters must match and the restult type is fixed), intrinsic functions accept arguments of...

  2D_Indoor_CQB_Robot_Simulation

Program Design Purpose: The integration of robots in Close Quarters Battle (CQB) represents a significant advancement in modern military and law enforcement tactics. These robots, designed to navigate tight spaces, gather real-time intelligence, and engage threats, are invaluable assets in high-stakes scenarios. Our goal is to develop a 2D tactical board simulation system, similar to a computer game, that can load building floor blueprints, display CQB squad (robot) positions, enemy locations, ...

  What’s the waiter doing with the computer screen?

When Richard Gatarski and a few friends wanted to dine in the Swedish city of Norrköping a few weeks ago, they booked a table at a downtown Italian restaurant that seemed nice. When they arrived, they were greeted by the headwaiter, who asked if they had a reservation. Richard confirmed, and the headwaiter looked at his computer screen. ”Gatarski? Hm, let’s see .. yes, there’s your reservation. Welcome!” The headwaiter then picked up what Richard first thought m...

  9 Ways to Create Thread Pools with Java Executors

In Java, the Executors class provides a variety of static factory methods to create different types of thread pools. When learning about thread pools, the Executors class is indispensable. Mastering its usage, principles, and scenarios will enable you to apply it smoothly in actual project development. Here are some commonly used methods, which I will explain one by one: newCachedThreadPool(): Creates a cached thread pool. If a thread has not been used for 60 seconds, it will be terminated and ...

  Remove duplicated elements in JavaScript array

During interviews, one frequent question asked would be something like how to remove duplicated elements in a JavaScript array and how many different ways you can think of. The interviewee would also be asked to write the code down. In real applications, normally front end would not need to handle this case since normally it would be done by backend, but still it's necessary for front end developers to know different ways of doing this. This post will share some of the common ways to remove dupl...

  Top 5 Reasons Not to Use Hadoop for Analytics

As a former diehard fan of Hadoop, I LOVED the fact that you can work on up to Petabytes of data.  I loved the ability to scale to thousands of nodes to process a large computation job.  I loved the ability to store and load data in a very flexible format.  In many ways, I loved Hadoop, until I tried to deploy it for analytics.   That’s when I became disillusioned with Hadoop (it just "ain't all that"). At Quantivo, we’ve explored many ways to deploy H...
