Computers started becoming popular with businesses in the 1960s and widespread in homes and schools in the 1980s. People now use computers for many purposes like banking, education, research, engineering, design, law enforcement, the military and more. Computers require both hardware, like processors, memory, and peripheral devices, as well as software programs and operating systems to function. Early pioneers invented the foundations of modern computers, but it was not until integrated circuits and transistors that computers became small enough for personal use in the 1970s and 1980s.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
"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.

Computers
You’ve probably known about computers your whole life.
But computers have not really been around for very long.
Computers started to become popular with big companies in
the 1960s. Computers didn’t become widespread in homes
and schools until the 1980s.
HOW DO PEOPLE USE COMPUTERS?
People use computers in many ways. Stores use computers
to keep track of products and check you out at the cash
register. Banks use computers to send money all over the
world.
Computers help teachers keep track of lessons and grades.
They help students do research and learn. Computers let you
hook up to networks (many computers hooked together). They
let you hook up to a worldwide network called the Internet.
Scientists use computers to solve research problems.
Engineers use computers to make cars, trucks, and
airplanes. Architects use computers to design houses and
other buildings. The police use computers to track down
2. criminals. The military uses computers to make and read
coded messages.
Computers are not just desktops and laptops. Computers
are everywhere around your home. There are tiny computers
inside microwave ovens, television sets, and videocassette
recorders (VCRs) or digital video disc (DVD) players. There
are even tiny computers in cars to help them run better.
HARDWARE AND SOFTWARE
Computers need hardware and software in order to work.
Your desktop or laptop and all the parts inside are called
hardware. The central processing unit (CPU) makes the
computer work. The keyboard, mouse, printer, and monitor
are also pieces of computer hardware.
Memory chips are hardware that stores information and
instructions. Information also gets stored on the hard disk
drive.
The programs that run the computer are called software. The
computer operating system is software that tells the
computer how to run. Applications or programs are software
that do certain tasks. Word-processing programs, for
example, let you write school reports and letters.
HOW CAN COMPUTERS DO SO MUCH?
One reason that computers can do so much is that they have
a special language that tells them what to do. Computer
language has only two letters: zeros and ones. Computers
can read these ones and zeros extremely quickly.
Each zero or one is called a bit. Eight zeros and ones
together are called a byte. Bits and bytes get stored in
computer memory chips. Every year, computer engineers
make chips that can hold more bytes. The chips can hold
more information. Programmers can write applications that
can do more things.
3. WHO INVENTED THE COMPUTER?
Many inventions have contributed to the development of
modern computers. French mathematician Blaise Pascal and
other inventors in the 1600s began making machines that
could add and subtract numbers. Wheels, levers, and other
moving parts made these machines work. In the 1800s,
British mathematicians Charles Babbage and Augusta Ada
Byron, countess of Lovelace, worked on plans for machines
that could store information on cards with holes punched in
them.
American inventor Herman Hollerith made a machine that
automatically totaled population figures for the 1890 United
States census. His company joined with other companies to
become International Business Machines (IBM) in 1924.
Other inventors built better computers. But none of these
early computers were digital—that is, none used the digits
zero and one.
The first digital computer, called ENIAC, was built in the
1940s. It was huge. It was as big as a house. It had more
than 18,000 glass tubes inside and weighed more than five
elephants.
The first computer used by business was called UNIVAC. Big
computers like ENIAC and UNIVAC were called mainframes.
The desktop or laptop computer that you use today is much
more powerful than those big machines.
In the 1940s, scientists at Bell Telephone Laboratories
invented a tiny electric switch called the transistor. In the
1960s, scientists and engineers invented integrated circuits
or computer chips. Computer chips cram millions of
transistors into a space the size of your little fingernail.
Computer chips allowed computers to be smaller.
Personal computers (PCs) were invented in the 1970s. Most
PCs are meant to be used by only one person at a time. They
4. are small enough to fit on a desk. The Altair 8800 was the
first PC. Apple Computer made its first PC in 1977. IBM made
its first PC in 1981.
WHO INVENTED COMPUTER PROGRAMS?
Computer programs are sets of instructions that tell a
computer what to do. Many people worked on early
computer programs. The first programs were very hard to
write and understand. They were extremely long strings of
zeros and ones.
American naval officer and mathematician Grace Murray
Hopper in 1952 wrote the first program that turned English
computer instructions into the strings of ones and zeros that
make computers work. These programs are called
compilers. In 1957, she helped develop the first programming
language that companies could buy and use. It was called
FLOW-MATIC. Hopper was also the first to use the word bug
to mean a problem with a computer. She found a moth
trapped in one of the computers she worked with. She taped
the moth into her notebook and wrote, “First actual case of
a bug being found.”
LATER DEVELOPMENTS
As computers have become more powerful and widespread,
operating systems have become extremely complex. Few
people can use a computer without one. Scientists at AT&T
developed an operating system called UNIX in 1969. UNIX
and related operating systems such as Linux are popular at
universities and among computer professionals. In 1975, Bill
Gates and his friend Paul Allen wrote a program for the Altair
8800 and founded the Microsoft Corporation. Microsoft later
developed the DOS and Windows operating systems used on
many home and office PCs.
Computers keep getting smaller and more powerful.
Personal computers that fit on a desktop today are more
5. powerful than early “supercomputers” that filled entire
rooms. Cell phones and watches contain tiny computers that
can store information such as telephone numbers,
addresses, and appointments. These devices allow you to
surf the Web and play games. Many computer experts think
that computers have only begun to make their mark on
history.
