Unit in the last place. In computer science and numerical analysis, unit in the last place or unit of least precision (ULP) is the spacing between two consecutive floating-point numbers, i.e., the value the least significant digit (rightmost digit) represents if it is 1.

Unit in the last place

It is used as a measure of accuracy in numeric calculations.[1] Definition[edit] Decimal floating point. Decimal representation of real numbers in computing Decimal floating-point (DFP) arithmetic refers to both a representation and operations on decimal floating-point numbers.

Decimal floating point

Working directly with decimal (base-10) fractions can avoid the rounding errors that otherwise typically occur when converting between decimal fractions (common in human-entered data, such as measurements or financial information) and binary (base-2) fractions. Implementations[edit] Early mechanical uses of decimal floating point are evident in the abacus, slide rule, the Smallwood calculator, and some other calculators that support entries in scientific notation.

What is event streaming?

Apache Kafka

Event streaming is the digital equivalent of the human body's central nervous system. It is the technological foundation for the 'always-on' world where businesses are increasingly software-defined and automated, and where the user of software is more software. Technically speaking, event streaming is the practice of capturing data in real-time from event sources like databases, sensors, mobile devices, cloud services, and software applications in the form of streams of events; storing these event streams durably for later retrieval; manipulating, processing, and reacting to the event streams in real-time as well as retrospectively; and routing the event streams to different destination technologies as needed. Event streaming thus ensures a continuous flow and interpretation of data so that the right information is at the right place, at the right time.

Kafka vs. RabbitMQ: Architecture, Performance & Use Cases. If you’re considering whether Kafka or RabbitMQ is best for your use case, read on to learn about the different architectures and approaches behind these tools, how they handle messaging differently, and their performance pros and cons.

RabbitMQ vs. Kafka. An architect’s dilemma. Introduction As a software architect dealing with a lot of Microservices based systems, I often encounter the ever-repeating question – “should I use RabbitMQ or Kafka?”.

RabbitMQ vs. Kafka. An architect’s dilemma

For some reason, many developers view these technologies as interchangeable. While this is true for some cases, there are various underlying differences between these platforms. As a result, different scenarios require a different solution and choosing the wrong one might severely impact your ability to design, develop, and maintain your software solution.

15 Free Games to Level Up Your Coding Skills - Skillcrush. When I started learning to code, the options were limited—lots of books (not even e-books), some very basic online tutorials, and a whole lot of experimentation.

15 Free Games to Level Up Your Coding Skills - Skillcrush

Coding games? Not so much. Online learning has come a long way in the last few years. There are interactive courses, tons of online tutorials, and one of my personal favorite ways to practice coding: fun free games! While a coding game alone probably isn’t going to teach you everything you need to know about coding, these free fun games can be a really incredible way to practice the skills you’re learning.

Heron-Centric: Ruminations of a Language DesignerThe Principles of Good Programmingby Christopher DigginsJuly 24, 2011 Today's post is a lightly edited repost from my blog at The Area, a web-site dedicated to users of Autodesk media and entertainment products.

The Principles of Good Programming

I came up with this list of principles to help with a recent C# training I gave, and I thought that members of the Artima.com community could appreciate these principles and have some interesting insights to share. The principles of good programming are closely related to principles of good design and engineering. The following programming principles have helped me over the years become a better programmer, and I believe can help any developer become more efficient and to produce code which is easier to maintain and that has fewer defects.
