New capabilities and use cases for blockchain and the real worldWHITEPAPER
Nillion allows nodes in a decentralized network to work in a unique, non-blockchain, way.
While Nillion represents a revolutionary leap from a predecessor technology known as Secure Multi-Party Computation (SMPC), unlike SMPC, network nodes do not have to communicate with one another. Unlike blockchain, nodes do not run immutable ledgers designed to store transaction data.
Instead, new Nillion technology, called Nil Message Compute (NMC), is purpose built for decentralized secure storage and computation and thus opens up new use cases (on the Nillion native network), while also enhancing existing blockchains.
Nil Message Compute (NMC) allows nodes in a permissionless, decentralized network to compute information in a non-blockchain, secure and verifiable way without having to send messages to one another.
Network nodes perform secure computations in a fault tolerant and decentralized manner at near client-server speed as there is no need for inter-node messaging.
NMC thus holds the promise of fast distributed computation between trustless nodes with special non-blockchain properties such as Information-Theoretic Security and instant consensus.
As the first fully decentralized, trustless, and permissionless NMC network for web3, Nillion ushers in a new era of decentralized use cases and computing.
The network will:

Exactly what is solar power?
Plants have the ability to harness power from the sunlight, so why cannot we? Solar power is produced by transforming the sunlight’s thermal power right into electric power. Solar power is one of the most plentiful renewable resource offered as well as produces tidy, trusted, and also cost effective electrical power without launching greenhouse gases and also various other air toxins. There are 2 methods which solar power can be exchanged power:
Photovoltaics: Solar batteries (PVs) alter sunshine straight right into electrical power.
Solar thermal/electric nuclear power plant: Solar thermal/electric nuclear power plant produce electrical energy by focusing solar power to warm a liquid and also generate heavy steam to power a generator.
Solar installments in the United States have actually ended up being far more prevalent, enhancing seventeen layer considering that 2008. When running at optimum problems our present solar ability could create adequate power to power 4 million American houses.
Good Reading: Agreenorigin Solar Powered Lamps
Just what are the pros of solar power?
1. Bountiful: Solar power is one of the most plentiful source in the world as well as has solid possibility in order to help us fulfill our expanding power needs. Presently, the globe eats regarding 15 terawatts of power (1 terawatt = 1 trillion watts). The sunlight down payments 173,000 terawatts (TW) of solar radiation externally of the Planet continually– that’s greater than 10,000 times our present power need! Remarkably, one does not have to survive on the equator to take advantage of solar power. Germany produces concerning 7% of its complete electric requirements from solar power.
2. No exhausts: Making solar energy does not launch unsafe discharges right into the environment.
3. Siting: Little range solar might be set up practically anywhere. Lots of solar panels might be positioned on roofs of existing structures– lowering their land impact. Massive solar thermal/electric nuclear power plant have a bigger land impact, as they need a great deal of area.
4. Reduced upkeep: When set up effectively, solar panels call for little upkeep.
Just what are the disadvantages of solar power?
1. Periodic: Solar power– while plentiful– is not consistent. The quantity of solar power striking the planet’s surface area differs depending upon the moment of day, season, climate patterns, and also area. A lot of cities experience the best need for power in the mid-day as well as early evening when solar power is unable to be caught it its best possibility. Solar power plants are likewise prone to adjustments in cloud cover and also weather condition patterns– a plant’s effectiveness could be dramatically endangered by a gloomy day or mid-day tornado.
2. Power storage space: One option to the difficulty of recurring power resources is buying power storage space. In these systems, batteries and also various other gadgets keep produced power for later usage. Power storage space systems right currently are expensive and also underdeveloped. We should make a dedication to progressing r & d in power storage space innovations, such as circulation batteries as well as grid power storage space systems, if we are serious about transitioning right into a brand-new power version where power needs are satisfied from eco-friendly resources.
3. Expense: It is really pricey to bring a solar plant on line. While technical breakthroughs as well as government rewards have actually triggered the price creating solar power to drop considerably over the past Twenty Years, solar power manufacturing is still more costly compared to coal as well as gas. One means to take a look at the competition of various power resources is to contrast levelized power prices. The levelized price of power (LCOE) is determined by taking the complete price to construct as well as run a brand-new nuclear power plant over its life time separated by its anticipated power outcome– determined in bucks each kilowatt hr ($/ kW-hr). Coal and also gas have reduced LCOEs ($.07-.$14/ kW-hr). The LCOE of solar energy is almost dual that of coal as well as gas, balancing in between $0.13 and also $0.24/ kW-hr.
* It is essential to keep in mind that expanding need for power paired with government motivations might reduce the levelized expense of solar power in the future. Solar power is economically-competitive with traditional power resources in numerous states, consisting of The golden state, Hawaii, Texas, and also Minnesota.
4. Rare earth products: Several solar batteries are made from rare earth minerals like silicon as well as various other steels like mercury, lead, and also cadmium. These products needed in PV cells can be unusual, costly, as well as possibly unsafe to the atmosphere.


SIGGRAPH Asia 2008: Parallel Computing for Graphics: Beyond Programmable Shading
Welcome to the course notes and supplementary materials for the full-day SIGGRAPH Asia 2008 Beyond Programmable Shading course!
The course was held at SIGGRAPH Asia 2008 on Friday, 12 December.
This course provides an introduction to parallel-programming architectures and environments for interactive graphics and demonstrates how to combine traditional rendering API with advanced parallel computation.
There are strong indications that the future of interactive graphics involves a more flexible programming model than today's OpenGL/Direct3D pipelines. That means that graphics developers will need a basic understanding of how to combine emerging parallel-programming techniques with the traditional interactive rendering pipeline. The first half of the course introduces several parallel graphics architectures, programming environments, and the new types of graphics algorithms that will be possible. The second half presents case studies of how game developers, researchers, and graphics hardware vendors combine traditional rendering API techniques with advanced parallel computation. Each case study includes a live demo and discusses the mix of parallel-programming constructs used, details of the graphics algorithm, and how the rendering pipeline and computation interact to achieve the technical goals.
The course presenters are experts on general-purpose GPU computation and advanced rendering from academia and industry, and have presented papers and tutorials on the topic at SIGGRAPH, Graphics Hardware, Supercomputing, and elsewhere.

After a successful launch from Cape Canaveral Air Force Station in Florida, the NASA spacecraft Juno is safely on its way to the planet Jupiter. To get into space, the large and heavy spacecraft was launched atop an Atlas V-551 rocket at 12:25 p.m. local time on August 5, 2011. The journey is to take five years, with Juno arriving at Jupiter in July of 2016. It is to complete 32 highly elliptical polar orbits by October 2017, when it is scheduled to make a de-orbit burn to intentionally crash into the largest planet in the solar system.
With its suite of scientific instruments, Juno will investigate the existence of a solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia within its deep atmosphere, and observe the planet’s auroras that are caused by its magnetic field. The Juno mission is the second spacecraft designed under NASA’s New Frontiers Program. The first was the Pluto New Horizons mission, launched in January 2006 and scheduled to reach Pluto’s moon Charon in 2015. Juno’s scientific payload includes a gravity/radio science system; a six-wavelength microwave radiometer; a vector magnetometer, plasma and energetic particle deflectors; a radio/plasma waves experiment; an ultraviolet imager/spectrometer; and an infrared imager/spectrometer. Juno also carries a high-definition color camera to provide detailed images of Jupiter’s poles.

Smart Technology: How Smart Is Your AP Data?
Many of us in the 1980s were mesmerized by the “Knight Rider” television series that featured the “KITT Car”, an interactive Pontiac Trans Am with a human-sounding voice and smart technology operations that far exceeded the capability of a normal automobile. The featured auto not only had the ability to react to changing conditions rapidly, but could also self-diagnose, providing extensive valuable internal and external data to its rider.
In the 1980’s, such an automobile was a dream in the mind of the writer, but technology has advanced so fast that today such innovations are becoming a reality. Smart technology is dramatically changing production in every major industry.
What is most compelling about these technological improvements is that they are altering the way day-to-day intelligence about normal business operations is collected and acted upon. Michael E. Porter and James E. Heppelmann examine the influence of smart technology on today’s business functions in their in-depth article, “How Smart, Connected Products Are Transforming Companies”.
Improved Sources of Data
Before smart technology existed, data within a business organization was collected slowly by various human activities. Surveys were taken, efficiency reports were written, customer response to products was evaluated and tirelessly measured to use as a basis for future business decisions. Departments such as accounts payable existed within an activity loop, where daily functions were carried out with little influence on the business as a whole.
AP automation is one type of smart technology, and it has changed everything about the way the average accounts payable department now interacts in today’s business. E-invoicing has elevated accounts payable to such a degree that major business decisions are being made based upon the electronic invoicing data obtained.
How Accounts Payable Must Adapt
Because such technology is under constant improvement, there is an increasing need for better responses to the data that is being originated, in the way that it is being combined, analyzed and controlled. It’s not enough just to receive better data; if businesses are to remain competitive, they must improve the way that such data is handled.
Accounts payable automation already contains within it the devices needed to make control of better data easier. Real-time information is uploaded automatically, with electronic archiving that makes comparison and analysis of data simpler and quicker. Electronic data sharing means that there no longer needs to be a lag time in the dispensing of important information that can affect other departments.
Computer parameters can be set to fine tune the data transfer, defining the boundaries of acceptable daily cash expenditure based upon budget allowances and expressed company goals. Problems can be resolved as they occur, even from remote locations. Electronic enablement’s such as dynamic discounting can be used to achieve better results with vendors, making payment of invoices quicker and more manageable.
There is no doubt that continual upgrading of software and systems will make an increasing demand on the accounts payable department of the future. However, electronic invoicing will continue to be improved to significantly shorten data response time, making the corporation as a whole more competitive.

Since building my brewery kit, I’ve managed to brew a few beers…
#1 – Dirty Daemon II – Detailed in my last post, an American APA with loads of Citra in the boil & dry-hopped.
#2 – A Christmas CarAle – A Christmas ale spiced with Star Anise, Cinnamon and Nutmeg. Based on Greg Hughes’ recipe in Home Brew Beer.
#3 – Oaty McOatFace – An Oatmeal Stout, based on James Morton’s recipe in Brew.
#4 – Unnamed – A Raspberry Wheat beer, based on Greg Hughes’ recipe in Home Brew Beer.
The one thing that all these brew days have had in common is mash temperature control issues & lower than expected efficiency (just under 60% I think). The temperature issue is probably down to the crappy insulation in the cooler box I’m using for the Mash Tun. Efficiency could be affected by a number of things, not least the dead space under the drain/filter.
Rather than fix the insulation, I’ve decided to feed my gadget habit and build a HERMS system. Click this link to find out more.
My HERMS system is going to be based on an Inkbird PID controller, a small Asparagus Steamer pot fitted with a kettle element, and a copper coil. The copper coil sits in the pot filled with hot water, my pump recirculates the wort from the mash, though the coil and back into the top of the mash tun. The PID controller monitors the heat of the wort and keeps it at a constant temperature by turning the kettle element on & off as necessary.
First up, the PID controller box…
- Project Box
- Inkbird PID Controller + 25A SSR
- SSR Heatsink
- PT100 Probe
- Terminal block
- Twin & Earth cable
- A 10A computer power cable I had spare
So, first of all, measure and cut out where the Inkbird and heat sink will be mounted…
Next, the old power cable was cut in half and the both halves fed through a cable hole in the side. The box is going to be wired as follows:
Live & Neutral to Inkbird terminals. Live to SSR switched terminal. Live from SSR terminal to output cable. Neutral to output cable. Earth to output cable. Inkbird SSR control terminals to SSR control terminals. Temperature probe to Inkbird probe terminals.
Double check the wiring and make sure it’s correct! Check against the Inkbird wiring documentation and check again.
Stick the lid on and give it a go!…
Sorted! Well, almost. Amazon sent me a K probe instead of the PT100 I ordered, so there’s a replacement on the way.

Is AI Advancing Too Quickly for Our Understanding? Unraveling the Enigma.
The Need for Transparency in AI
Artificial intelligence (AI) is rapidly changing every aspect of our lives, from healthcare and education to business and entertainment. However, as AI development continues to soar, the question of whether we are moving too quickly to properly comprehend its ramifications is raised.
The Black Box Problem
One of the main issues with the quickly developing AI is the lack of transparency, sometimes known as the “black box” problem. This means that we often do not understand how AI systems make their decisions, which can make it difficult to identify and correct errors, assess the ethical implications of AI use, and develop effective regulations.
Why Transparency Matters
There are many reasons why it is essential to comprehend how AI functions. First, knowing how an AI system makes decisions might help it correct errors if they occur. Without this understanding, it will be challenging for us to improve or fix AI technology. This could have major ramifications, particularly in crucial industries like healthcare or driverless vehicles where mistakes could result in potentially fatal circumstances.
Second, ethical issues are becoming more prominent as AI has a greater impact on our daily lives and social systems. For instance, AI applications in police or facial recognition could possibly violate private rights or encourage bias. Effectively controlling these technologies becomes a difficult task without a thorough grasp of them.
Addressing the Transparency Problem
There are a number of initiatives underway to address the transparency problem in AI. The Explainable AI (XAI) project, which intends to make AI decision-making comprehensible, is currently under development. Similar to this, governments, academic institutions, and the corporate sector are working together to develop efficient AI regulatory frameworks. Additionally picking up steam is public education regarding AI, which will aid society in better comprehending and adjusting to AI breakthroughs.
Even though AI is developing quickly, it’s crucial that knowledge and laws maintain pace with these developments. Transparency, moral considerations, and public awareness will be crucial as we navigate the AI revolution in ensuring that AI technology is developed and used responsibly. The aim should be to maximize possible benefits for society as a whole while reducing risks and harm. In order to make sure that AI acts as a tool for advancement rather than a source of confusion and doubt, it is a difficult challenge that we must rise to.


What is Continuous Ink Jet
Continuous Ink Jet systems (CIJ) work by expelling electrically charged ink droplets from a print head nozzle and passing them through an electric field.
The ink jet brakes into drops inside the chamber through a pulse from the piezoelectric crystal.
The droplets charged, pass through an electrostatic field between deflector plates. A combination of speed and charge determines the correct position of the droplet on the substrate.

Lithium-ion nominal cell voltages
The nominal voltage of lithium-ion is normally 3.60V per cell. Some cell manufacturers mark their Li-ion as 3.70V/cell or higher.
How is a cell's nominal cell voltage defined?
The nominal cell voltage is the average voltage a cell outputs when charged.
Parallel chains which tend to be self balancing since the parallel connection holds all the cells at the same voltage. Being in parallel allows charge to move between cells freely.
Therefore it is only necessary to balance groups of cells that are in series.


On the way to 60
TUNIK, which was used by A. Turan Kurtcebe in 1965, is in the production phase of electronics manufacturers.
At the time of Turkey’s meeting with television, the production process of the electromechanical switching business with 10 people, TUNİK, has started to produce the most parts of the electronics industry for the overall biggest game, Profilo and Koç Group.
With its innovative and quality team of 450 people, TUNİK managed to become the largest passive component manufacturer in our country in a very short time by producing cablehearnes as well as electro-mechanical components for all electrical and electronic manufacturers of Turkey.
Produce in Turkey consume in the world
With our rapidly growing country’s economy in the 80s and the increase in exports, TUNİK’s quality production also attracted the attention of multinational electronics companies. Project collaborations for the Turkish electronics market were realized with Philips Holland, the largest connector and cable hearness manufacturer of the period.
This union opened its overseas doors to TUNİK. In addition to multinational brands such as Ericsson, Motorola, Northern Telecom, Grundig, Philips, Turkey’s leading companies in television production and export, Profilo Telra has become the most important supplier of companies such as Vestel, Beko and Arçelik.
Thus, components with the TUNIK signature began to be used in most of the televisions produced both in Turkey and in foreign markets.
Collaboration with international brands
In the process of rapidly advancing the electronics industry, TUNİK, which is constantly pursuing innovations, carried out production-oriented R&D studies with Japanese Hitachi, – Lucent, -IDB Telecom, -Quartez in order to respond to the needs of the sector.
When Jindal Stainless, the world’s second largest company producing electrical and electronic components, entered the Turkish market, it chose TUNİK. Together with the jointly established company, investments were made in the fields of metal and mining, which are the most important raw materials of the electrical-electronics sector. In addition, Network Electronic, one of the largest electronics companies in Europe, preferred TUNİK for its project partnership in its investments in Turkey.
Firsts of TUNIK
- The first company in Turkey to receive ISO 9001 and UL certificates
- Turkey’s first floppy disc production system was established.
- Taximeters used in taxis
- Fuse holder used in the defense industry
- Provided consultancy services to the establishment of the electronic infrastructure in the process of establishing Turkey’s first GSM system together with the Lucent company.

- Construction of the system created to prevent the communication between Israel and the Turkish Red Crescent during the earthquake.
- Production of Northern Telecom system 12 switchboard
- The most important GSM distributor boxes of our country
- We were cable harness supplier to Elbit
Turan Kurtcebe, the Founder and Chairman of the Board of Directors of TUNİK, who has a different vision in the electrical and electronics sector, led the establishment of the Turkish Electronics Industrialists Association by showing the success of bringing the electronics sector together.
Along with this formation, it also assumed an important role in the electronic and telecom structuring process of our country with the relevant ministries.
Social responsibility projects
TUNİK and its Founder Turan Kurtcebe, who are involved in studies that also value human health, also took part in the founding board of trustees of Turkey’s first private Medical Faculty and hospital.
