Top 5 Social Entrepreneurs and How They Nailed ItSimplify360
Â
Entrepreneurship is one of the most prominent things in today's date. However, social entrepreneurs are still a few. Not many have been able to reach great heights with their ideas.
We have listed 5 ways which successful entrepreneurs adopted to make it big. Here's how they nailed it.
Social really is here when it comes to the enterprise. Many see the role of social in consumer-focused businesses but have not absorbed what it means for the enterprise. Social is having a direct impact in 5 areas:
1. DIY prospecting: Customers conduct research on products and services well ahead of the official start to the sales cycle
2. Peer influence: Customers “pulse” their peers at every step of the journey
3. Trial before purchase: User testing requires grassroot support. It’s no longer a single decision instance rather smaller purchase bundles
4. Buyer & user are the same: The phenomenon changes decision and influence points in enterprise purchasing
5. Click to compare: Pricing transparency is foundational; consumer expectations are shaping enterprise behavior

Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.[1][2]
By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is hard or rigid with respect to changes, whereas software is soft because it is easy to change.
Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware.
Von Neumann architecture
Main articles: Von Neumann architecture and Stored-program computer
Von Neumann architecture scheme
The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms.[3] The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.[4]
Personal computer
Basic hardware components of a personal computer, including a monitor, a motherboard, a CPU, a RAM, two expansion cards, a power supply, an optical disc drive, a hard disk drive, a keyboard and a mouse
Inside a custom-built computer: power supply at the bottom has its own cooling fan
The personal computer is one of the most common types of computer due to its versatility and relatively low price. Desktop personal computers have a monitor, a keyboard, a mouse, and a computer case. The computer case holds the motherboard, fixed or removable disk drives for data storage, the power supply, and may contain other peripheral devices such as modems or network interfaces. Some models of desktop computers integrated the monitor and keyboard into the same case as the processor and power supply. Separating the elements allows the user to arrange the components in a pleasing, comfortable array, at the cost of managing power and data cables between them.
Laptops are designed for portability but operate similarly to desktop PCs.[5] They may use lower-power or reduced size components, with lower performance than a similarly priced desktop computer.[6] Laptops contain the keyboard, display, and processor in one case. The monitor in the folding upper cover of the case can be closed for transportation, to protect the screen and keyboard. Instead of a mouse, laptops may have a touchpad or pointing

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Â
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.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Â
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Â
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Â
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

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).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Â
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
Â
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

5. Hub
Hubs are devices that have many ports into which network
cables are plugged. A hub takes the signal from each
computer and sends it to all of the other computers
through the network. Hubs come in different sizes and
colors. The hub must be plugged in and turned on for the
network to work - be sure you see green lights
Modem A device that allows computers to communicate with each
other over telephone lines (Internet). At school we do not
use modems, we have a direct connection to the Internet
called a T-1 line.
Keyboard Input device - choose letters, symbols, and actions by
pressing keys
Key Any of the buttons on a keyboard that the user presses to
input data (information) or to type commands
Escape Usually pressed while you are working in a software
application to stop the current activity, back out of a
menu (or screen), or return to a previous screen.
Enter Used to move the cursor to the beginning of a new line. It
may also be called the return key. In some applications,
pressing Enter tells the computer to stop waiting for more
input and begin processing. Notice the arrow symbol on
the Enter key; it is sometimes used in instructions and
means to press the enter key.
Backspace Moves the cursor one space to the left, erasing any
character that is in its path
6. Spacebar Moves the cursor one space to If the spacebar is "split",
(split the right, leaving a small blank the left "spacebar" acts
spacebar) white area (space) on the like the backspace key - it
screen. erases the character to
the left of the cursor.
shift Does nothing by itself, but when pressed and held down
with another key it makes either a capital letter or the
upper character on a key. Pressing Shift with a letter key
when the CAPS LOCK key is "on" makes a lower case
letter.
caps lock Makes all letters uppercase without having to use the
shift key - it is best to only use this when you are going to
make many letters uppercase - don't use for just a few
capital letters
tab Marked with two arrows, one pointing left, the other,
right. If pressed by itself, it moves the cursor to the
next tab on the right. When pressed with the Shift key,
it moves the cursor to the previous tab stop on the left.
alt Does nothing by itself. When pressed with another key, it
performs a special function. For example, pressing Alt-F4
may quit a currently running program.
ctrl Does nothing by itself. When pressed with another key, it
performs a special function. For example, pressing Ctrl-S
may "save" a document.
Num Lock Typically "on" at start up. When "on", it changes the keys
on the numeric keyboard from cursor control arrows to
numbers arranged in a typical ten-key calculator keypad.
Delete On our "Windows" computers (P) it erases the character
to the right of the cursor. Some people say it performs a
"forward erase". It operates differently on a MAC.
End The key you press to move the cursor to the end of the
current line. Many programs also use keyboard shortcuts
such as Ctrl+End to move the cursor to the end of a
document.
7. Insert Changes between insert mode and overstrike mode in word
processing programs. In insert mode, all characters typed
are placed at the cursor position (or to the right of the
insertion point). As you type, anything to the right of the
cursor moves to the right to make room for the new
typing. If insert mode is turned off, typing then
overwrites (erases) the old characters instead of putting
the new ones before the old ones. This is often called
overwrite mode. Most PC keyboards have an Ins or Insert
key that lets you switch back and forth between insert
and overwrite modes. Many word processing programs
display OVR in a status bar at the bottom when overwrite
mode is on.
Home The key you press to move
the cursor to the
beginning of the current
line. Many programs also
use keyboard shortcuts
such as Ctrl+Home to move
the cursor to the
beginning of a document.
PgDn The function of this key is usually software
specific. Typically, it scrolls a document backward one
screen or one page.
PgUp The function of this key is usually software
specific. Typically it scrolls a document forward one
screen or one page.
Arrows 4 keys that move the cursor in the direction the arrow
points
Function
Keys Special keys that perform a number of important
(F1, F2 tasks. Their exact functions are software dependent. F1
...) usually is reserved for Help, while F10 frequently exits or
quits the program.
Print Screen It directs the computer to copy whatever is displayed on
the screen to the clipboard for pasting later. It doesn't
really "print" in Windows.
8. Scroll Lock Its function is often software specific. In spreadsheets,
it usually locks the cursor on its current screen line and
scrolls text (rather than the cursor) up or down whenever
an up or down cursor control arrow is pressed.
Pause Not usually used with Windows. Pressing this key under
DOS temporarily stops a screen display or freezes rapidly
scrolling information.
Windows Key The WINDOWS key acts as another special function key.
If you press the Window key by itself, the Start
Menu will open. Windows+E will launch Windows Explorer.
