Decentralised financial systems are a series of financial applications built on a decentralised register, better known as blockchain. The way blockchains are structured and used has many implications for the financial industry. To take the definition of DeFi a little further, decentralized finance considers a system designed to function without a central authority. [Sources: 4]*
Decentralised Finance (DeFi) is a new approach that uses a public, distributed register that supports autonomy and creates a peer-to-peer financial network. The new system does this without relying on a central authority and its users interact via decentralised applications (Dapps) running on peer-to-peer (P2P) networks. [Sources: 4, 6]*
Decentralized finance, or simply DeFi, refers to financial applications built on a blockchain network. More specifically, the term decentralized finance could refer to a movement aimed at creating a decentralized financial system that is open to all and operates without central authority. The de-fi ecosystem consists of decentralised applications (Dapps) that function as authorization-free services, meaning that users do not rely on intermediaries to process their requests. [Sources: 5, 6]*
Users interact with the ecosystem through decentralized applications and would retain full control of their assets. In addition, users interact directly with each other and with other users of the decentralised application, such as traders and investors. [Sources: 5]*
Moreover, the financial revolution is trying to create an ecosystem of financial services that is accessible to everyone and allows everyone to take full control of their financial assets. Blockchain technology, in particular, has enabled this kind of decentralized financial ecosystem to be introduced in the first place. Because DeFi wants to get rid of the central financial authority, it means that anyone can access a wide range of assets, including stocks, bonds, and other financial instruments. [Sources: 7]*
Since DeFi does not require intermediate parties, all would interact decentrally in the ecosystem. Cryptocurrencies like Bitcoin were created to make it easier for people to exchange values with others around the world. This desire has arisen from a new movement within the cryptoindustry known as decentralized finance, or "DeFi." [Sources: 4, 7]*
The DeFi movement takes cryptocurrencies a step further, but it is still building on the underlying technology that drives them, and it is going a step further with a few adjustments. Decentralized finance, or "DeFi," is the latest innovation emerging from blockchain - the decentralized energy economy. De Fi is about applications that build on a blockchain, a decentralized ledger that tracks all transactions on its blockchain publicly. [Sources: 0, 4]*
This decentralised, borderless way of doing things allows anyone with an Internet connection to have access to financial products and services. DeFi applications, which are mainly based on the Ethereum network, offer users traditional financial services. Today, a de-Fi user can borrow, lend, invest, make payments, and make purchases and loans in a decentralized manner without financial institutions or intermediaries, which he can do today without a financial institution or intermediary.  In Venezuela, Venezuelans have introduced bitcoin to protect their wealth from government manipulation and hyperinflation. [Sources: 8]*
Today's infographic is from the Abra investment app, a plug-and-play app that allows people to intuitively use decentralized financial services without the complexity of centralized systems. How could public blockchain help decentralized financial systems? [Sources: 3, 8]*
Decentralized finance describes new decentralized financial systems based on public blockchains such as Bitcoin or Ethereum. After all, Bitcoin and Ethereum are not the only blockchain systems that could be used to change the way the global economy works. The initialization of blockchain use cases with Bitcoin has shown that value moves faster and more efficiently than any other financial system in the world. [Sources: 1, 8]*
Ethereum makes digital money highly programmable and enables distributed users to execute code in the form of smart contracts. Beyond speculation and value storage, Ethereum allows many aspects of traditional finance to run on an open network with a ramp - upwards, allowing the creation of new types of assets such as stocks, bonds, and other financial instruments. [Sources: 1]*
Just four years after the launch of Ethereum, transactions worth more than $1 trillion were processed through Ethereum, and more than $13 billion was completed through smart contracts from Ethereum. With over 13 million users on the Ethereum network, decentralized finance has become the most active sector in the blockchain space, with $14 billion of its value going to Ethereum's smart contract. Just four years after its launch, just over half of the world's top 100 financial institutions, including Goldman Sachs, Morgan Stanley, JPMorgan Chase, Bank of America, Citibank, JP Morgan Chase, and Wells Fargo, are part of this experiment. [Sources: 1, 2]*
Decentralised financial systems take over traditional financial systems that run on a central infrastructure managed by central authorities, institutions and intermediaries. By providing invariable smart contracts on Ethereum, DeFi developers have created a financial protocol platform that runs exactly as programmed and is available to anyone with an Internet connection. The code runs on a decentralized infrastructure, the Ethereum blockchain, without central authority or intermediaries responsible for its operation. [Sources: 2]*

Chapter 1 Project initiation
1.1 Concepts
The project initiation phase should gather from enough information to define the project and the essential characteristics of the study site. In particular, information should be gathered about:
1.1.1 Site choice and basic characterization
The boundaries of the study area should be defined. Depending on the study scope and vision different approaches could be used ( hydrological, political, ecological). Some classification frameworks: (Rosgen1994?) UNEP (2017)]
1.1.2 Project resources
Several assessment tool exist [link].
In relation to data gathering four dimensions are proposed as a starting point: budget, capacity, level of engagement with the community and level of data uncertainty.
Budget. Understanding available budget for the task (and its allocation across different expenditure types) is an essential information in planning an appropriate strategy.
Capacity could be assessed with a particular focus on methods that could be used for data acquisition. This could include field sampling techniques, laboratory analysis, skills in geospatial and remote sensing disciplines, hydrological modelling, statistical and numerical methods.
1.1.3 Stakeholder engagement
Community engagement. An important factor that is gaining recognition is the involvement of communities in environmental monitoring. This approach is able to produce, even with limitations, not only robust data but also increase awareness and improve people behaviours toward the environment.
1.1.4 External data requirements
When gathering data to be reported to an already established framework/legislation, minimum data requirements may exist (number of data points, level of uncertainty).
1.1.5 Initial condition scenarios
To simplify all the possible combination amongst the aforementioned factors and reach some level of generalization in the following step, three scenarios are proposed. Their aim is to describe some common situations
Scenario 01: low resources – In this alternative, low financial resources are assumed. Methods are chosen based on cost. A medium to high level of capacity is assumed.
Scenario 02: low uncertainty – This scenario aims at reducing the uncertainty of sampling and analysis. Nevertheless a trade-off with cost and resources needs to be found.
Scenario 03: Participation of local communities Simpler methods involving citizen science and monitoring are used. More frequent, cheaper, less accurate monitoring and sampling are preferred.

SEC approves 15 new securities worth N154.62bn in Q3
by Agency ReportThe Securities and Exchange Commission approved new securities worth N154.62 billion in the third quarter of 2019.
The commission disclosed this in its current Nigerian Journal of Securities Market obtained by the News Agency of Nigeria in Lagos on Monday.
A breakdown of the figure showed that a total of 15 new securities were approved during the period under review.
These, according to SEC, consist of three right issues, one private placement, one offer for subscription, five new offers for registration and five corporate bonds.
The commission noted that this was contrary to one right issue, six new offers for registration and three corporate bonds valued at N123.5 billion approved in the second quarter.
It added that a total of nine Federal Government bonds valued at N201.86 billion were allotted by the Debt Management Office during the period.
The commission explained that the figure was inclusive of allotments done on a non-competitive basis.
“While equal number of bonds were issued in Q2 2019, the amount allotted was N305.55 billion, indicating a decline of 33.93 per cent in value of bonds issued in Q3,” it said.
The commission stated that the total number of new issues during the period under review stood at 24, while total value stood at N356.48 billion.
On the secondary market issue, SEC said that a total of 13.87 billion shares valued at N177.02 billion were sold at the Nigerian Stock Exchange (NSE) in Q3.
It explained that this was lower when compared with 25.52 billion shares worth N329.61 billion recorded in Q2, indicating depreciation of 46.29 per cent in value.
An analysis of Federal Government bonds indicated that trading value dropped to N287.24 million from N998.51 million in Q2.
Transaction volume and value of Exchange Traded Funds also fluctuated throughout the quarter under review.
Specifically, 2.13 million units of ETF valued at N57.37 million exchanged hands in Q2, while it closed with the sale of 174.94 thousand units at N13.76 million.

Introduction
The goal of this page is to give visual intuition and best practices for some of the tuning done in gradient-based MCMC algorithms, while providing links to papers or other works that give more rigorous, careful results.
Hamiltonian Trajectories
Given a (differentiable) target probability distribution, \(\pi\), an initial position \(\mathbf{q}\) and an initial momentum \(\mathbf{p}\), we may solve a certain differential equation The differential equations are $$ \begin{align} \frac{d \mathbf{q}}{dt} &= M^{-1}\mathbf{p} \\ \frac{d \mathbf{p}}{dt} &= - \frac{\partial}{\partial \mathbf{q}} \log \pi, \end{align} $$ where \(M\) is the mass matrix that we discuss later. to generate Hamiltonian trajectories:
Hamiltonian Monte Carlo
If we integrate each trajectory for a fixed length You can also use a dynamic length if you are careful! See The No-U-Turn sampler: adaptively setting path lengths in Hamiltonian Monte Carlo by Hoffman and Gelman. This NUTS algorithm is the basis for libraries like Stan and PyMC3. and then resample the momentum, the stationary distribution for the endpoints of the trajectories is \(\pi\), our target distribution.
Note that we have not yet talked about how to integrate these trajectories, we are just talking about a world in which we could.
The leapfrog integrator
Of course, we need to think about how to solve the differential equation from earlier. As a reminder, $$ \begin{align} \frac{d \mathbf{q}}{dt} &= M^{-1}\mathbf{p} \\ \frac{d \mathbf{p}}{dt} &= - \frac{\partial}{\partial \mathbf{q}} \log \pi, \end{align} $$ \(\mathbf{q}\) is position, \(\mathbf{p}\) is momentum, \(\pi\) is our target distribution, and \(M\) is the mass matrix that we discuss later. For one thing, we will be using a leapfrog integrator, which is a second order integrator. Here it is on our toy distribution, compared with (in red) Euler's method.
We can compare this to a leapfrog integrator with even a very large step size, where the errors will compound more slowly The error compounds like \(\mathcal{O}(h^3)\), instead of \(\mathcal{O}(h^2)\) for Euler's method (where \(h\) is the step size). Additionally, and arguably more importantly for HMC, the leapfrog integrator is symplectic, so volumes are preserved, the integrator doesn't spiral out to infinity, and the changes in energy tend to stay bounded. , though there is eventually some very obvious differences in the trajectories!
Choosing a step size
We ignore here how long to integrate An active area of research! NUTS is commonly used, and has a dynamic trajectory length, but will end up costing about twice as much as using HMC with a fixed step size. Other approaches are ChEES-HMC, which seeks to automatically adapt HMC's trajectory length, or empirical HMC which uses a fixed distribution of trajectory lengths. , but will focus on the step size being used. It turns out that HMC speed will scale linearly with the number of steps, so 20 steps of length 0.1 will take 10 times as long as 2 steps of length 1. There is less accuracy Perhaps disastrously! Geometric integrators and the Hamiltonian Monte Carlo method by Bou-Rabee and Sanz-Serna is a terrific survey. with longer steps, and a Metropolis-Hastings correction is necessary.
Balancing step size length and integration error is an exercise in stochastic root finding Using something like Robbins-Monro (as in Andrieu and Thoms), or a dual-averaging scheme (as in the NUTS paper). , with a goal of accepting around 65% of proposals for HMC, and 80% for NUTS. In case your posterior is Gaussian or nearly Gaussian whose covariance has eigenvalues \(\lambda_1^2, \ldots, \lambda_N^2 > 0\), A Condition Number for Hamiltonian Monte Carlo by Langmore, Dikovsky, Geraedts, Norgaard, and Von Behren gives the pleasant formula $$ \left(\sum_{n=1}^N\left(\frac{\lambda_1}{\lambda_n}\right)^4\right)^{1/4} \approx \frac{\lambda_1}{h} 2^{7/4}\sqrt{\Phi^{-1}\left(1 - 0.5 P[\text{accept}]\right)}, $$ where \(h\) is the step size, and \(\Phi^{-1}\) is the inverse normal CDF.
Another way to think about integration error
Just for fun, we can consider trying to integrate along a trajectory of fixed length, while steadily increasing the step size, and watching the integration error. It is worth mentioning that the total energy (log probability of the position plus log probability of the momentum) along a Hamiltonian trajectory should remain constant. In case the total energy at a point is more than 500 less than at the start, software like Stan, PyMC3, and TensorFlow Probability will label the trajectory a divergence and short-circuit integration, rejecting the proposal.
Mass matrix adaptation
The mass matrix is the matrix \(M\) from earlier, which we get to choose when we choose a momentum distribution for HMC So \(M^{-1}\) will be the covariance for a multivariate Gaussian that the momenta are drawn from. It may be more pleasant to think of the mass matrix as the inverse of the gradient of the kinetic energy. : $$ \begin{align} \frac{d \mathbf{q}}{dt} &= M^{-1}\mathbf{p} \\ \frac{d \mathbf{p}}{dt} &= - \frac{\partial}{\partial \mathbf{q}} \log \pi, \end{align} $$ Using a mass matrix is equivalent I can't believe it took this long to cite Radford Neal. to the change of coordinates \(X \rightarrow LX\), where \(M^{-1} = LL^T\). This transformation is shown below:
The HMC sampler is particularly efficient on a standard normal target distribution, so we try to choose a mass matrix so that this equivalent transformation causes our distribution to transform into a standard normal.
More explicitly:
Given an estimate of the posterior covariance \(C\), we will set our mass matrix to be \(C^{-1}\).
In fact, this is how mass matrix estimation works (at least in TensorFlow Probability, Stan, and PyMC3): after a few draws with the identity mass matrix, the mass matrix is set to to the running covariance. Really, there is a windowed scheme: every so often, we throw out earlier draws, and only use more recent ones. See this talk for more detail on that. We spend some portion of our computational budget on estimating the mass matrix and step size, before fixing these two parameters and actually running MCMC. While changing step sizes and momentum distributions, we are not necessarily sampling from the target distribution, so the tuning samples are discarded. On the other hand, this tuning period obviates the need for a "burn-in", since it usually provides enough chance for the sampler to get near the typical set.
As an illustration of what can go wrong, we run the same adaptation scheme on our running mixture-of-Gaussian example, and we see that it ends up adapting to a single mode.
Conclusions
This is not overly novel or new, but is hopefully a graphical, intuitive demonstration of some of the parameters that are tuned and discussed in gradient-based MCMC. Remember that pictures are not proof, and that low dimensional intuition is not always trustworthy in the sorts of high dimensions where we often use HMC or NUTS.

Pixl: Scaling & Saving Art [part 3]
-
In part one of our tutorial, we got a pretty good start with a grid that refreshes gracefully based on a data array. The user can toggle a single colors on and off for each pixel.
-
In part two we added a color palette and mouse-dragging functionality to paint pixels more quickly.
What’s happening today?
Now we’re going to enable the user to save their masterpiece. We’ll offer the option to scale to 16px, 32px, 64px, or 128px and the choice of transparent vs solid color backgrounds. Finally, we’ll display all the generated canvases in a tray at the bottom of the app.
Let’s get started.
First we’ll create a div to hold the controls and the image tray of completed canvases.

<button id="getImage">get image</button>

transparent
<input id="transparent" type="checkbox" checked>

bgcolor
<input class="jscolor" id="bgColor">

width
<select id="pxWidth">
<option value="16">16px</option>
<option value="32">32px</option>
<option value="64">64px</option>
<option value="128" selected>128px</option>
</select>

Note the use of checked
and selected
in our input
and options
tags: this attribute specifies the default selected value. We’re allowing the user to scale the drawing to some select multiples of 16. You could enable the user to input a number and scale to any size they’d like, but for simplicity, we’re limiting the range to four options.
See Hick's Law : the more choices you give the user, the longer it takes them to make a decision. Corollary: if you give a user too many choices, they might make the decision to close the tab.
Generating the canvases requires two steps.
- Listen to the “get image” click event & get the parameters from the user
- Scale the canvas based on these parameters and display it in the
imageTray
Let’s do the easy part first.
1. Listen and Fetch Parameters
document
.getElementById("getImage")
.addEventListener("click", getUserImageParameters);
document
.getElementById("bgColor")
.addEventListener("change", updateBackgroundColor);
We add a listener to the background color picker. By default, backgrounds are transparent, and we have the transparency checkbox ticked. When the user changes the background color, we simply untick the transparency box. If the user re-checks transparency, we will not display any background color, even if the user has already selected one.
Unchecking the box is one way to help out the user by anticipating their intention–choosing a background color for the image means they probably want one—-but providing a quick visual if they change their minds.
function updateBackgroundColor(e) {
let T = document.querySelector("input#transparent");
T.checked = false;
}
Our getUserImageParameters
handler grabs the values of the pixel width, transparency, and background color at the time the button is clicked and calls grabCanvas
to display the user’s image: the function that we’re about to write!
function getUserImageParameters(e) {
e.preventDefault();
let W = document.querySelector("select#pxWidth").value;
let T = document.querySelector("input#transparent").checked;
let BG = "#" + document.querySelector("input#bgColor").value;
grabCanvas(W, T, BG);
}
2. Scale the canvas
Now that we know what size canvas the user wants, we need to scale it and set the background color (either to transparent or to the selected color).
We’ll write a function grabCanvas
that takes a width, transparent flag (true/false) an a bgColor from the user. It will output a canvas to the display that is scaled and has the specified background color.
In order to scale the main canvas, we’re going to create a second, smaller canvas. We number it with a unique id that we increment on the page with the creation of each canvas, cvsID
. We give the canvas a height & width based on the user selection. We add a class to the canvas so that we can style it with CSS, and then we use prepend
to add it to the imageTray
div.
We use prepend
(Docs)
to add the canvases instead of appendChild
(Docs)
because we want the newest canvases to appear on the leftmost side of the div. When more canvases are added than can be viewed, we’ll automatically scroll to the far left of the div so the most recent canvas can be viewed.
cvsID++;
let blit = document.createElement("canvas");
blit.height = width; // px
blit.width = width;
blit.classList.add("c-output");
blit.id = "cvs_no" + cvsID;
let blitCtx = blit.getContext("2d");
const cellDim = Math.ceil(width / NUM_COLS);
let tray = document.getElementById("imageTray");
tray.prepend(blit);
tray.scrollLeft = 0;
Now that we have the canvas on screen, we just have to draw the cells.
To do that I wrote a box-drawing function called colorScaledBox
. It’s very similar to colorBox
. Indeed, we could have simply refactored colorBox
, but there would be a bit of complication involved: we’d have to rework colorBox
to take a context and a flag for whether a grid should be drawn.
const cellDim = Math.ceil(width / NUM_COLS);
function colorScaledBox(box, color) {
const { row, col } = box;
if (!isValidCol(col) || !isValidRow(row)) {
return false;
}
blitCtx.fillStyle = color || currentColor;
blitCtx.clearRect(col * cellDim, row * cellDim, cellDim, cellDim);
blitCtx.beginPath();
blitCtx.fillRect(col * cellDim, row * cellDim, cellDim, cellDim);
blitCtx.closePath();
}
Setting the background color is actually quite easy. We loop through the canvas data and use our new function colorScaledBox
.
To determine which colors to change (either to a specified background color, or to a transparent square), we compare the color of each square to the DEFAULT_COLOR
. If the square’s color is the same as DEFAULT_COLOR
, this means that the user never painted here. We either set the square to transparent or to the specified background color.
Otherwise, the user did paint here. We ignore the background color parameters since this square is not part of the background and we paint the user’s color selection.
for (var i = 0; i < canvasData.length; i++) {
let row = Math.floor(i / NUM_ROWS);
let col = i % NUM_COLS;
let color = canvasData[i];
if (transparent) {
if (color === DEFAULT_COLOR) {
colorScaledBox({ row, col }, "rgba(255,255,255,0)");
} else {
colorScaledBox({ row, col }, color);
}
} else {
if (color === DEFAULT_COLOR) {
colorScaledBox({ row, col }, bgColor);
} else {
colorScaledBox({ row, col }, color);
}
}
}
Saving Off Images
The user can now just Right-click > Save Image on a canvas, and they get precisely-sized pixel art:
Right click save-as?!
I hear ya. You’re groaning at the desk. Is this 1995? I thought this was a web app! Never fear my friend. In the next part of the tutorial, we’ll cover usability enhancements such as these:
- allowing the user to delete canvases from the
imageTray
- maintaining a “gallery” of art (saving and deleting via localStorage for later editing)
- a more graceful way to save images from the app
And what about the CSS?!
It’s true that I have not covered styling for the app yet and am just throwing in some basic CSS to make things look decent as we move along. At the end of the tutorial series, I will cover styling extensively and show how we can make the app appear responsive at different screen sizes using mobile-first design and media queries. Stay tuned!

This experience was by no means my first with alcohol and I have drunk much greater quantities than this, but as a result of the speed at which I consumed the booze, this is the most drunk I have ever been.
I was going through a minor depression of sorts, and I really wanted to just have a few beers with my friends. It was a Saturday evening, and I had done nothing exciting the whole weekend thus far. I was itchin' to be in an altered state of mind. I made some phone calls but everyone was unavailable. I figured I'd just buy a little thing of booze and get a slight buzz going and relax in my bedroom.
Telling my parents that I was going for a bike ride (I am 21 but live at home; my parents don't mind drinking but would disapprove of my drinking alone) I headed down to the Liquor Commission and bought a mickey (13oz) of Bacardi white rum. I got on my bike and headed out to a semi-secluded wooded area where I lay on the riverbank and forced down a few shots. I probably had about 4.5 ounces or so. Feeling a slight buzz, I stuffed some gum in my mouth, stuck the mickey in my pants under my shirt, and returned home. I poured a huge glass of orange juice and went back to my room. I drank about a third of the OJ and poured rum in until it was full again. It wasn't too nasty, and I kept gulping it while I watched TV. I had a bit of a buzz, but not much, so after the OJ was gone, I finished the rest of the bottle. I laid down in my bed and stared at the ceiling, wondered why I wasn't very drunk.
That is the last thing I remember.
I woke up at 5:30 am with a blinding headache and a bone-dry mouth.  There was so much vomit I knew it had to be a dream. Although I was painfully hung over, I was relieved to wake from my awful dream. I knew I had been drunk the night before, and figured I had just passed out in front of the TV, but I could remember nothing.
Something was wrong though. It was the middle of winter, and I had awoke wearing only my briefs. Even in the summer I always wear a t-shirt to bed.
I stood up and wracked my brain. An image of me hugging my own toilet popped into my head. I checked the toilet and there was no evidence of vomit. I guess I had remembered to flush. I was quite alarmed that I had zero recollection of the previous night's events. I went downstairs to see if I had knocked anything over or something, because I could have done anything and I'd never remember.
When I got to the bottom of the stairs the smell hit me. Wretched, rancid puke smell. I looked into the living room and there it was: the coffee table was absolutely COVERED in puke except for two places: where I had tried to wipe it with my shirt, and where I had tried to wipe it with my pants. Evidently I didn't make much of an effort to clean it before deciding it was hopeless and going back to bed I guess.
I cleaned my puke reasonably well before my parents saw it, but when my dad asked me why I was up so early I said it was to clean up my puke (I was still half-drunk). He assumed I had gone to a bar the night before, until my mom told him I was home the whole night. My parents asked me if I was having 'problems' and I said no, and that I had learned my lesson about drinking alone. I had.

FROM:BARR.ROTIMI BELLO (ESQ)NO.5 MILVERTON STREET, VICTORIA-ISLAND LAGOS<EMAIL_ADDRESS>Dear Sir/Madam, I am Barrister Rotimi Bello, a solicitor at law. I am the personal attorney to Mr. Douglas Raju, a national of your country, who used to work with shell development company in Nigeria and as well a one time secret agent in transferring of money overseas for the Late head of state of Nigeria {Late Gen.SANI ABACHA}.Before his death On the 21st of April 2002 [my client,his wife and their only daugther were involved in a car accident along sagamu express way in which all occupants of the motor died}. My client {RAJU}deposited the sum of $15.5m in a commercial bank(CENTRAL BANK OF NIGERIA) here in Nigeria for himself, with the hope of transferring it to his country as soon as he is on leave. Since his death I have made several enquiries to your embassy to locate any of my clients extended relatives this has also proved unsuccessful. After these several unsuccessful attempts, I decided to trace his last name over the Internet, to locate any member of his family hence I contacted you. I have contacted you to assist in repatriating the money and property left behind by my client before they get confiscated or declared unserviceable by the bank where these Money were Deposited. Particularly, the (CENTRAL BANK OF NIGERIA) where the deceased Deposited (US$15,500,000)fiftheen million five hundred thounsand dollars has issued me a notice to provide the next of kin with in the next ten official working days. Since I have been unsuccessful in locating the relatives for over 3years now I seek your consent to present you as the next of kin of the deceased since you have the same last name so that the proceeds of this deposit (Money) valued at (US$15,500,000)fiftheen million five hundred thounsand dollars can be claim by you and then you and me can share the money. 40% to me and 60% to you I have all necessary legal documents that can be used to back up any claim we may make. All I require is your honest cooperation to enable us see this deal through. I guarantee that this will be executed under a legitimate arrangement that will protect you and me from any breach of the law.

| Moon phase = degrees. | |
Above is a table of the current Moon phase along with predictions of the next four quarters of the Moon's orbit. It is updated every second.
This is a sample page for the open-source Astronomy Engine. All of the source code and documentation is available there. Also, try using your browser's View Source command to look at how this page works.
The phases of the Moon are calculated using relative ecliptic longitudes. This means that the Moon's position is measured as an angle away from the Sun counterclockwise as seen from above the Earth's north pole. This is the same direction as the Moon orbits the Earth.
The angle is defined along the ecliptic plane, which is the plane of the Earth's orbit around the Sun. The Moon does not stay within this plane, so its position above or below the ecliptic plane is ignored for the sake of calculating phases. This is the way almanacs and calendars historically have reported the dates and times of moon phases.
The phase angle increases from 0 degrees to 360 degrees over the span of each synodic month. Certain values of the phase angle define the four lunar quarters:
In your own code, to calculate the Moon's current phase angle, call
the function Astronomy.MoonPhase
.
To predict upcoming lunar quarter phases, call
Astronomy.SearchMoonQuarter
passing in a Date object to find the first quarter phase after that date and time.
Then if you want, you can call
Astronomy.NextMoonQuarter
in a loop to iterate over the next consecutive quarter phases.
Each time, you pass the return value of the previous function call as the argument
to Astronomy.NextMoonQuarter
so it knows where to resume the search.
Here is an example that finds the next 100 lunar quarter phases:
let date = new Date();
let mq = Astronomy.SearchMoonQuarter(date);
console.log(mq.quarter, mq.time.date);
for (let i=1; i < 100; ++i) {
mq = Astronomy.NextMoonQuarter(mq);
console.log(mq.quarter, mq.time.date);
}


Viktor Orbán: Western Europe is Finished, Central is the Future
“We want to live as free nations, not as provinces or subordinates to empire.”
by Paul Joseph WatsonHungarian Prime Minister Viktor Orbán says that the situation in western Europe means that the continent must look to central European countries like Hungary and the Czech Republic for a bright future.
Orbán gave a speech in Prague on Sunday in memory of the 1989 Velvet Revolution in 1989, which saw the end of Communist rule in Czechoslovakia.
“Thirty years ago we thought that Europe was our future, but today we think we are Europe’s future, and we are ready for this mission,” said Orbán.
The Prime Minister warned that globalists in western Europe are currently in the process of wiping out a European society based on nation states and Christian culture and that central European countries were standing up to this.
“We want to live as free nations, not as provinces or subordinates to empire,” said Orbán, adding, “We are Central European Democrats. Therefore, we must defend the sovereignty of nation states, because if we abandon it, it will mean the end of democracy.”
One way Orbán is trying to rebuild his country is by encouraging its citizens to have children in order to eliminate the need for mass immigration.
Hungary is offering €30,600 to married couples who have three or more children.
A married couple receives the €30,600 as a loan from the government upon getting married. The loan then has to be repaid until the couple has three children. At this point, the debt is completely forgiven.
The impact of pro-family policies in Hungary has been massive.
Abortions dropped from 40,449 to 28,500 from 2010 to 2017, divorces fell from 23,873 in 2010 to 18,600, and marriages increase by a huge 42 percent.

Poor error prevention. Stressful evening. Thanks a lot, Apple.
In a previous post I touched on Nielsen’s “10 Usability Heuristics for User Interface Design“. Though 20 years old, these nuggets still ring true.
Here’s a biggie:
Error prevention:
Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.
There’s more good stuff about errors and how to prevent them on the NNG site.
I recently fell foul of what I consider to be an inexcusable lack of error prevention.
Using Apple’s native Mail application on my Macbook, I searched for the out-of-office feature. It doesn’t exist (pity). Apparently I needed to set up a rule, to send a friendly message in reply to any incoming email, letting the sender know I’ll be sunning myself in Norway.
All good so far, and one final action for me to take:
The offending window in MacMail – poor error prevention
Sure, I was in a bit of a hurry to log off and go on holiday, but of course the choice was obvious – I clicked the welcoming blue button.
Two minutes later I got a call from my line manager, who was heading home on the train. His phone was going BING, BING, BING, BING, BING, BING, BING, BING, BING, BING – attracting the attention of other commuters, until he switched it to silent, but the emails had kept flooding in. 300 of them or so. (My only saving grace is that I’d only joined the company a couple of months previously, so the number of emails were limited.)
I retraced my steps and realised that that enticing blue button had applied my rule to ALL emails in my inbox, which meant a reply had been sent to EVERY email I’d EVER received letting my colleagues (including the CEO and various others) know I’d be on holiday.
I’m not – the – first – person this has happened to.
Apple die-hards may dismiss this as user error, and sure – I make mistakes like anyone now and again – but I maintain that this hugely embarrassing, unexpected consequence of such a common, ostensibly simple task was far too easily done.
The issues:
1. Mail should have an out-of-office feature. #
Debacle prevented.
2. Why, why, why would I ever want the actions I took to lead to the results that occurred? #
I cannot envisage a single reasonable scenario where any user would want to send the same reply to every single old email in their inbox. It simply shouldn’t have been possible for this to happen.
3. It shouldn’t have been so easy. #
Even if it had to be possible (which it didn’t), it was far too easy for me to click that button, considering the seriousness of the results.
There’s plenty of research about how little people read online, and the impact and psychology of colours. So, 100% scientifically, this is what my brain processed when I saw that confirmation window:
Scientifically, what my brain processed
Putting aside the issue that this result shouldn’t have been possible in the first place, there are options which might reduce the likelihood of errors.
For example:
- swapping the buttons, to make ‘Don’t Apply’ the default
- showing ‘Apply’ as text (rather than a button) to further distinguish it from the preferred option
- adding a warning symbol and/or warning explanation to ‘Apply’
- rewording the window to make the action and consequences clear (the copy at the moment is very unclear, in my view) and changing the wording on the ‘Apply’ button to something more specific like ‘Reply to every single email in your inbox, even though you’d never ever want to do so’ (er… or maybe something a little more concise)
- A confirmation ‘Are you sure?’ pop-up, or the option to undo before the changes kick in.
And so on.
4. Users hate errors #
When poor system design leads to serious consequences for the user that could and should have been avoided, that’s about as frustrating as it gets in terms of user experience. Error prevention isn’t the most glamorous part of UX but there’s nothing more important.
I’ve stopped using Mac Mail.


There are two ways to start using Capacitor: adding Capacitor to an existing frontend project (recommended), or starting a fresh project. Capacitor was designed primarily to drop-in to existing frontend projects, but comes with a simple starting project structure if you'd like to start fresh.
Capacitor provides a native mobile runtime and API layer for web apps. It does not come with any specific set of UI controls which you will most likely need unless you're building a game or something similar.
We strongly recommend starting a Capacitor project with your mobile frontend framework of choice (such as Ionic).
Make sure you have all the required Dependencies installed for the platforms you will be building for. Most importantly,
make sure you update CocoaPods using pod repo update
before starting a new project, if you plan on building for iOS using a Mac.
Capacitor was designed to drop-in to any existing modern JS web app. A valid package.json
file and a folder containing all web assets are required to get started.
To add Capacitor to your web app, run the following commands:
cd my-app
npm install --save @capacitor/core @capacitor/cli
Then, initialize Capacitor with your app information.
Note: npx
is a new utility available in npm 5 or above that executes local binaries/scripts to avoid global installs.
npx cap init
This command will prompt you to enter the name of your app and the app id (the package name for Android and the bundle identifier for iOS). Use the --web-dir
flag to set the web assets folder (the default is www
).
Next, install any of the desired native platforms:
npx cap add android
npx cap add ios
npx cap add electron
🎉 Capacitor is now installed in your project. 🎉
Capacitor comes with a stock project structure if you'd rather start fresh and plan to add a UI/frontend framework separately.
To create it, run:
npx @capacitor/cli create
This command will prompt you to enter the name of your app and the app id (the package name for Android and the bundle identifier for iOS).
This will create a very simple starting app with no UI library.
Make sure you have the Required Dependencies installed, including PWA Elements, then proceed to the Developer Workflow Guide to learn how Capacitor apps are built.

The single responsibility principle states that every module or class should have responsibility over a single part of the functionality provided by the software.
In object-oriented programming, the open/closed principle states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification"; that is, such an entity can allow its behaviour to be extended without modifying its source code.
Substitutability is a principle in object-oriented programming that states that, in a computer program, if S is a subtype of T, then objects of type T may be replaced with objects of type S (i.e. an object of type T may be substituted with any object of a subtype S) without altering any of the desirable properties of T (correctness, task performed, etc.).
The interface-segregation principle (ISP) states that no client should be forced to depend on methods it does not use. ISP splits interfaces that are very large into smaller and more specific ones so that clients will only have to know about the methods that are of interest to them.
The interface-segregation principle (ISP) states that no client should be forced to depend on methods it does not use. ISP splits interfaces that are very large into smaller and more specific ones so that clients will only have to know about the methods that are of interest to them.
The essential idea is to break down writing a scenario (or test) into three sections, known as a Given-When-Then style:
The given part describes the state of the world before you begin the behavior you’re specifying in this scenario. You can think of it as the pre-conditions to the test. The when section is that behavior that you’re specifying. Finally the then section describes the changes you expect due to the specified behavior.

About Covid-19
Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and
recover without requiring special treatment. Older people and those with underlying medical problems like
cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious
illnesses.
The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the
disease it causes, and how it spreads. Protect yourself and others from infection by washing your hands or
using an alcohol-based rub frequently and not touching your face.
The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected
person coughs or sneezes, so it’s important that you also practice respiratory etiquette.
Preventative Measurements
- Wear the mask properly covering the nose and mouth
- Wash hands with soap and water frequently for 20 seconds at least.
- Avoid hand shaking and kissing at meetings.
- Dispose of used wipes safely.

Symptoms of COVID
- High body temperature.
- Hacking cough.
- Vomiting.
- Runny nose.
- Shortness of breath.
- Pneumonia.
- In severe cases, one has severe symptoms: acute pneumonia, kidney inability.
How it Spreads
- Direct transmission through droplets from the patient when coughing or sneezing.
- Direct transmission (touching surfaces and devices contaminated with the secretions of the patient, and then touching the mouth, nose or eye).
- Direct contact with corona virus patients.
