Lossless compression is a data compression technique that reduces the size of a file without sacrificing any original data. It allows for an exact duplicate of the original file to be recreated. Common lossless compression techniques include run-length encoding and the Burrows-Wheeler transform. Run-length encoding replaces runs of identical characters with the character and number of repeats. The Burrows-Wheeler transform rearranges data to group similar characters together in order to compress more efficiently with run-length encoding.
Types of Data compression, Lossy Compression, Lossless compression and many more. How data is compressed etc. A little extensive than CIE O level Syllabus
In computer science and information theory, data compression, source coding,[1] or bit-rate reduction involves encoding information using fewer bits than the original representation.[2] Compression can be either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression.

The Playfair cipher was the first practical digraph substitution cipher. The scheme was invented in 1854 by Charles Wheatstone but was named after Lord Playfair who promoted the use of the cipher. In playfair cipher unlike traditional cipher we encrypt a pair of alphabets(digraphs) instead of a single alphabet

Video streaming using light-weight transcoding and in-network intelligenceMinh Nguyen
In this paper, we introduce a novel approach, LwTE, which reduces streaming costs in HTTP Adaptive Streaming (HAS) by enabling light-weight transcoding at the edge. In LwTE, during encoding of a video segment in the origin server, a metadata is generated which stores the optimal encoding decisions. LwTE enables us to store only the highest bitrate plus corresponding metadata (of very small size) for unpopular video segments/bitrates. Since metadata is of very small size, replacing unpopular video segments/bitrates with their metadata results in considerable saving in the storage costs. The metadata is reused at the edge servers to reduce the required time and computational resources for on-the-fly transcoding.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

2. Compression
the process of coding that will effectively reduce
the total number of bits needed to represent
certain information.
3. Lossless Compression
• data compression technique that reduces
the size of a file without sacrificing any
original data
information from the file is still
there, nothing is deleted
lets you recreate the original file exactly
• suitable for: text and computer code
• example: ZIP archiving technology
(WinZip & PKZIP)
5. Lossless Compression
pro. exact duplicate of the original file
con. compression ratio is not all that high
Compression ratio is the ratio of the size or rate of the
original data to the size or rate of the compressed data.
6. Lossless Compression
Principle of Lossless Compression Algorithms
any non-random file will contain duplicated
information that can be condensed using statistical
modeling techniques that determine the probability
of a character or phrase appearing
9. Run-Length Encoding
compression technique that replaces runs
of two or more of the same character with a
number which represents the length of the run,
followed by the original character; single
characters are coded as runs of 1.
11. Burrows-Wheeler Transform
o technique invented in 1994 that aims to
reversibly transform a block of input data such
that the amount of runs of identical characters is
maximized.
o does not perform any compression operations,
it simply transforms the input such that it can be
more efficiently coded by a Run-Length Encoder
or other secondary compression technique.
12. Burrows-Wheeler Transform (cont’d)
Algorithm
I. Create a string array.
II. Generate all possible rotations of the input
string, storing each in the array.
III. Sort the array alphabetically.
IV.Return the last column of the array
