Solar power harnesses energy from the sun through two main methods - photovoltaics and concentrating solar power. Photovoltaics directly convert sunlight into electricity using solar cells made from semiconductor materials, while concentrating solar power uses mirrors or lenses to focus sunlight onto a receiver to generate heat for electricity production. Both methods have various commercial applications but concentrating solar power can operate on a larger scale. The effectiveness of solar power depends on location, with sunny desert areas ideal due to higher solar radiation levels, and it also varies seasonally with more energy collected in summer.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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.

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.
Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...SOFTTECHHUB
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
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.

2. Solar Energy
• Solar energy is the energy
that is coming from the
sun.
• It can be collected by
human through
photovoltaics and heat
engines.
• Solar Power, along with
wind, hydroelectric, wave,
biomass account for most
of the renewable energy
source available to use.
3. Photovoltaics. (8.4.1.2)
• Photovoltaics is the direct
conversion of light into
electricity at the atomic
level.
• A photovoltaic cell(PV) is a
device that converts sun
light into direct current
through photoelectric
effect.
• Individual PV cells are
electricity-producing
devices that are made of
semiconductor materials.
• The photoelectric effect is
first noted by French
physicist Edmund Bequerel
in 1839.
• The first PV cell was
constructed by Charles Fritts
in 1880.
• The first major usage of PV
cell is on the Vanguard I
satellite in 1958.
• The increase in oil price, and
the increase in production
brought the price of
photovoltaic cell down.
4. Continue
• PV cells come in different
shapes and sizes. It can
be the size of a stape, or
several inches.
• Depending on the level of
need, the PV cells can be
put together to form a field
or a single module for
residential usage.
• The photoelectric effect
causes some materials to
absorb light photons and
convert them into
electrons.
• In general, photovoltaic
modules and arrays
produce DC electricity.
• The most commonly used
photovoltaic device is in a
single junction or interface.
• A multijunction device is a
stack of single junction
cells together serving as
the collector.
• Research are being done
on Gallium Arsenide,
Amorphous Silicon, and
Copper Indium Diselenide.
5.
6. Solar Heating Panel (8.4.12)
• Concentrating Solar Power
or (CSP) is another way of
collecting energy from sun.
• Concentrating Solar Power
system is made up of
lenses, mirrors, and
tracking systems focusing
a large amount of sunlight
into a smaller beam.
• The concentrated light
heat up a working fluid and
is then used as the heat
source for power
generation or energy
storage.
• The most developed
methods for CSP are solar
trough, parabolic dish, and
solar power tower.
• Unlike photovoltaics, CSP
can be used at a larger
scale and is more energy
efficient. Unlike PV which
converts solar ray directly
into electricity, CSP
system use heat to
generate a motor in order
to create energy.
7. Continue
• Each method of
concentrating solar power
convert different amount of
energy.
• In a solar trough, the
working fluid is heated up
to 150-350 °C, then it is
used as the hearing source
to a power generation unit.
• In the parabolic system,
the working fluid is heated
up to 250-700 °C. The heat
is then used by a stirling
engine to generate
electricity.
• In the solar power tower
unit, the working fluid is
heated up to 500-1000 °C.
Then it is used for power
generation or energy
storage.
• Ultimately, a solar power
tower offer more energy
efficiency and can store
more energy than a solar
trough system.

11. Seasonal and Regional Effect. (8.4.13)
• Solar Power, unlike
hydroelectric, wave it can
not be controlled by
human. Thus the regional
and seasonal effect on
solar power is greater than
the other renewable
resources.
• First,a solar power should
be station at a well lit area.
For example the desert
area or high ground where
the intensity of the sunlight
is highest.
• Second, solar power can
be collected all year round,
it will gather more sun light
during the summer due to
more day light.
• Areas such as the
Saharan desert, Nevada,
California, Australia etc are
good places to build a
solar power system
because they are the well
lit area on earth.

14. Photovoltaics (8.4.14)
• Example of a Photovoltaic module,
• Another example would be the building 678 PV Rooftop
System at Naval Air Station North Island, San Diego, CA.
Where they installed a PV system generating 30.54 MW of
power in 2000, with 198 panels each producing 116 watts.
15. Concentrating Solar Power (8.4.14)
• An Example of CSP is the SEGS plant in California, where
the plant has the installed capability of 354 MW of power,
and the general gross output is 75 MW of power, the station
receive an average of 340 days of sun light and the direct
normal radiation is 7.44 kwh/m²/day, (310 W/m²).
