From Square Numbers to Square Roots (Lesson 2) jacob_lingley
Students will use their understanding of square numbers to evaluate square roots. Remember, square roots, quite literally mean going from square numbers, back to the root - the number which you multiplied in the first place to get the square number. Example: The square root of 49 is 7.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
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.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. Describe how to round a number to a given place
value or significant figure.
When Rounding a number you always have to check the
number on the right. If it’s lower than 5 then you can’t
round it and all the other numbers on the right become
0. If it’s greater than 5 then you can round it to the
next significant figure.
3. Rounding Examples
Round 89,475 to the hundredth place.
The hundredth place is 4 and the tenth’s place, 7, which is greater than
5, therefore you can round 4 to the next value which is 5.The result is
89,500
If you want to round to one significant figure then
you go backwards 89,475, so the 8 will be the
significant figure and when you round it it becomes 9
so it will be 90,000
If you want to round to two significant figures it will
be the 9 round it and it will be 89,000
4. Translating English to Math
When translating English into Math, firstly you must
know the math to English dictionary. For example
Max scored 2 times more goals than bob, It will be
M=2B,also we don’t 2xB because in algebra when
you write 2B you know it’s 2xb.
Example 2. John has 4 more apples than Carlos=
J=4tC
Example 3. Alex has 3 apples less than Ralph= R= A-3
Example 4. Jackie and Bruce scored 3 times less goals
than Justin and Jason= J+B= U+N/3
5. Index Notations
Index notations are a different way to express numbers
as a result of multiplication.
Example 1. 3x3x3=27
Example 2.6x6x4=36x4=144
Example 3.7x7x7x2=343x2=686
6. Square Number
A square number is a number by the power of 2. We
don’t say by the power of two we usually say 2
squared. We call it a square number because square
numbers are like finding the area of a square.
Example 1: 2=22 = 4
Example 2: 3=32 = 9
Example 3: 4=42 = 16
7. Cube Numbers
A cube number is the same thing as a square, but
instead of power of 2 is power of 3 and we write it
like this 43. We call it a cube number because cube
numbers are like finding the volume of a cube.
Example 1: 4=43 = 64
Example 2: 5=53 = 125
Example 3: 6=63 =216
8. Order of Operations
The order of operations is how math problems can be
organized so you get the right answer. It is really
important if they give you a problem like this: 50(10+15)-
30 you’ll be able to figure it out. If we didn’t have the
order of operations everyone would get a different
answer
Step 1. Parenthesis
Step 2. Exponents
Step 3. Division
Step 4. Multiplication
Step 5. Addition and Substraction
Remember always start from left to right
9. Order of Operations Examples
Example 1. 65+(10-5)-9=61, Always do parenthesis
first .
Example 2. 49(8/64)+23=424, In algebra when the
number is next to the math problem you don’t add
you multiply.
Example 3. 37+(4/8x10)100= 570, Always remember
the order of operations and always go from left to
right or you will get it wrong.
10. Factors
The numbers that are being multiplied in a
multiplication are called the factors of the final
number.
Example 1. The factors of 12 are 1,2,3,4,6,12
Example 2. Factors of 6: 1,2,3,6
Example 3: Factors of 14: 1,2,7,14
11. Intergers
Intergers are all the numbers below and above zero, or
all the negative and positive numbers. Intergers are
important because they are used in today’s world for
calculations, equations etc.
Example 1. -5
Example 2. 28
Example 3. -1200
12. Adding and Subtracting Intergers
Adding and subtracting intergers is pretty easy if you know
the key rules. When it’s -3+7 it will be 4,but when it’s
double negative like this: -5+-14, you add, so it will be -
19. If it’s a double negative with brackets -3-(-4) you also
add
Example 1.-14-(-13)=-1
Example 2. -25+-16=-41
Example 3. -14+15=1
Key Rules Addition: If signs are the same add up the
numbers and keep the sign.
Key Rules Subtraction: Add the opposite.
13. Multiplying and Dividing Intergers
Multiplying and dividing intergers is the same thing as
adding subtracting except that you have multiply and
divide and you have to know the key rules.
Key Rules: If there are two different signs the answer
has to be a negative number. If the signs are the
same it has to be a positive number.
Example 1. -8x7=-56
Example 2. -10x-10= 100
Example3. -4/20=-5
14. Square Roots
Square roots is the opposite of square numbers. Before
doing square roots you must first know the perfect
squares and key rules. For example square root of 16
is 4 square root of 64 is 8.
Key Rules: “what number times itself = x”?
Example 1. Square root of 9 is 3
Example 2. Square root of 49 is 7
Example 3. Square root of 6 is approximate to 2.5
15. Cube Roots
Cube roots are the same thing as square roots except
it’s the opposite of cube numbers. Before doing cube
roots you also need to remember your perfect cubes
and squares and key rules.
Key Rules: “What number times itself 3 times = x”?
Example 1. Cube root of 27 is 3
Example 2. Cube root of 8 is 2
Example 3. Cube root of 6 is approximate to 1.8
16. How do we Find Higher Power Roots of
Numbers?
Finding power roots of higher numbers is the same thing as
cube roots and square roots except it’s a higher number than
3. For example fourth roots, are: “ a number times itself 4
times = x”. Same with fifth roots, sixth roots and so on.
Example 1. Fifth root of 3125 is 5, 5 times itself 5 times equals
3125
Example 2. Fourth root of 16 is 2, because 2 times itself 4 times
equals 16
Example 3. Sixth root of 24 is 1.69838133, when a number like
this shows up on your calculator just round it off to one or two
decimal places and you will get an approximate value of the
sixth root of 24. It will be 1.7, 1.7 times itself 6 times = 24
