Struct Direction
Structure representing the concept of a "direction" on a grid, and "defines" the coordinate plane via the YIncreasesUpward flag. Interacts with Point to allow easy translation of positions in a direction, and contains numerous helper functions for retrieving directions in various orders, getting direction closest to a line, etc.

Syntax
[DataContract]
public struct Direction : IEquatable<Direction>, IMatchable<Direction>
Remarks
The static YIncreasesUpward flag defines the way that many algorithms interpret the coordinate plane. By default, this flag is false, meaning that the y-value of positions is assumed to DECREASE as you proceed in the direction defined by Up, and increase as you go downward. If the coordinate plane is displayed on the screen, the origin would be the top left corner. This default setting matches the typical console/computer graphic definition of the coordinate plane. Setting the flag to true inverts this, so that the y-value of positions INCREASES as you proceed in the direction defined by Up. This places the origin in the bottom left corner, and matches a typical mathematical definition of a euclidean coordinate plane, as well as the scene coordinate plane defined by Unity and other game engines.

YIncreasesUpward
Whether or not a positive y-value indicates an upward change. To set this value, use SetYIncreasesUpwardsUnsafe(Boolean), however note that this is an unsafe operation in a multi-threaded environment where one or more threads may be using Directions. It is intended that this configuration be done as part of an initialization routine.
Declaration
public static bool YIncreasesUpward { get; }
Property Value
| Type | Description |
|---|---|
| Boolean |
Remarks
If true, directions with an upwards component represent a positive change in y-value, and ones with downward components represent a negative change in y-value. Changing this to false (which is the default) inverts this.

vi
Tutorial
vi
has two modes - command mode and insert mode.
In command mode, you are not directly typing text into the file.
Instead, you are giving commands like delete a single line, delete several lines, paste several lines, replace all instances of “hello
” with “howdy
”, save the file, quit, move the cursor, and so on.
At any time, to get into command mode, you hit the esc
key.
In insert mode, you can type normally.
There are a few ways to get into command mode:
i
: insert text at the cursora
: insert the text immediately following the cursoro
(lowercase letter): makes a new line for text after the cursorO
(uppercase letter): makes a new line for text before the cursorBelow is a set of very useful vi
commands which apply in command mode:
h
: move leftl
: move rightk
: move upj
: move downG
: go to the end of the file/hello
: go to the next instance of “hello
” in the filedd
: delete the current line of textp
: paste the last deleted text below the cursorP
: paste the last deleted text above the cursorJ
: tack next line to end of current lineNote that these all move into insert mode.
a
: insert after current cursor spoti
: insert before current cursor spotI
: insert text at the beginning of current lineo
(lowercase letter): insert blank line after cursorO
(uppercase letter): insert blank line before cursorNote the use of the colon (:
) before these commands.
:w
: saves the file:q
: quits the program:q!
: quits program without saving:wq
: saves the file and quits the programNote the use of the colon (:
) before these commands.
:%s/hello/howdy/g
: replaces all instances of “hello
” with “howdy
”:5,7s/hello/howdy/g
: replaces all instances of “hello
” in lines 5
through 7
with “howdy

Given a lens, a callback and a record, apply the lens to the record, transform it by the callback and return copy of the record, updated to contain the result of the callback. This is the fundamental operation on a lens and SET and VIEW are implemented in terms of it.
A lens is any function of the form (lambda (fun) (lambda (rec) ...))
that obeys the lens laws (where == is some reasonable equality
operator):
(== (view lens (set lens value rec))
value)
(== (set lens (view lens rec) rec)
rec)
(== (set lens value2 (set lens value1 rec))
(set lens value2 rec))
The inner lambda returns a functor that determines the policy to be
applied to the focused part. By default, this only uses IDENTITY- and
CONSTANT- in order to implement the lens operations over, set and
view.
If these conditions are met, (over (data-lens:<>1 lens1 lens2) ...) is equivalent to using lens2 to focus the part lens1 focuses: note that composition is "backwards" from what one might expect: this is because composition composes the wrapper lambdas and applies the lambda that actually pulls a value out of a record later.

Chapter 4
|
|
|
1 Now behold, it came to pass that I, Jacob, having
ministered much unto my people in word, (and I cannot write but a little of
my words, because of the difficulty of engraving our words upon plates) and
we know that the things which we write upon plates must remain;
|
Jacob explicitly states that engraving words on plates is
difficult and the reason he cannot write a lot. Yet consider for example all
the chapters of Isaiah that Nephi copied. Reviewing the many redundant and
unnecessarily verbose passages in the Book of Mormon and considering Occam’s
razor, which is more likely: that the Book of Mormon really comes from
ancient writings on golden plates or that it comes from a 19th century mind
or minds?
|
|
2 But whatsoever things we write upon anything save it be
upon plates must perish and vanish away; but we can write a few words upon
plates, which will give our children, and also our beloved brethren, a small
degree of knowledge concerning us, or concerning their fathers—
|
|
|
3 Now in this thing we do rejoice; and we labor diligently
to engraven these words upon plates, hoping that our beloved brethren and our
children will receive them with thankful hearts, and look upon them that they
may learn with joy and not with sorrow, neither with contempt, concerning
their first parents.
|
|
|
4 For, for this intent have we written these things, that
they may know that we knew of Christ, and we had a hope of his glory many
hundred years before his coming; and not only we ourselves had a hope of
his glory, but also all the holy prophets which were before us.
|
Jacob 4:4-5
As piotrkaplanstwo points out at www.reddit.com/r/exmormon/comments/4b7j1x/week_by_week_debunking_jacob_14
“An interesting assertion. I very much believed this when I read the Book of
Mormon as a believer. But, it does not withstand even the slightest bit of
scrutiny. If the ancient prophets worshiped Christ, BY NAME, then why are
there no references to him in any records whatsoever? We’d have something by
Abraham or Moses or Noah, or Adam even. Isaiah? The closest we get is a
generic ‘Messiah’ that is to save the Israelite nation. With so many writings
still around, how would we not have one single reference to Christ?”
|
|
5 Behold, they believed in Christ and worshiped the
Father in his name, and also we worship the Father in his name. And for
this intent we keep the law of Moses, it pointing our souls to him; and for
this cause it is sanctified unto us for righteousness, even as it was
accounted unto Abraham in the wilderness to be obedient unto the commands of
God in offering up his son Isaac, which is a similitude of God and his Only
Begotten Son.
|
Annotation for Jacob 4:4-5 above
|
|
6 Wherefore, we search the prophets, and we have many
revelations and the spirit of prophecy; and having all these witnesses we
obtain a hope, and our faith becometh unshaken, insomuch that we truly can
command in the name of Jesus and the very trees obey us, or the mountains, or
the waves of the sea.
|
This would be remarkable. It is similar to the miraculous
stuff of the Bible. It’s very different from the stuff of modern churches and
reality I am aware of.
|
|
7 Nevertheless, the Lord God showeth us our weakness that
we may know that it is by his grace, and his great condescensions unto the
children of men, that we have power to do these things.
|
|
|
8 Behold, great and marvelous are the works of the Lord.
How unsearchable are the depths of the mysteries of him; and it is impossible
that man should find out all his ways. And no man knoweth of his ways save it
be revealed unto him; wherefore, brethren, despise not the revelations of
God.
|
This is a particularly interesting premise. We are
basically told here that God’s thoughts and ways are beyond us. Couple this
with D&C 19:6-12 (where God tells us he uses certain language differently
than is commonly understood), then aren’t we left unable to trust anything
purporting the will or nature of God? If someone claims to preach the will of
God, how do we know they are not misled since God’s thoughts are so beyond a
mere mortal and (according to D&C 19:6-12) what is communicated as truth
about or from God may be easily misunderstood? How would one know she has not
been fooled and that the Muslims are right, or that Catholics really are the
only ones with apostolic authority, especially when many of them claim the
Spirit of God has told them so?
|
|
9 For behold, by the power of his word man came upon the
face of the earth, which earth was created by the power of his word.
Wherefore, if God being able to speak and the world was, and to speak and man
was created, O then, why not able to command the earth, or the workmanship of
his hands upon the face of it, according to his will and pleasure?
|
|
|
10 Wherefore, brethren, seek not to counsel the Lord, but
to take counsel from his hand. For behold, ye yourselves know that he
counseleth in wisdom, and in justice, and in great mercy, over all his works.
|
|
|
11 Wherefore, beloved brethren, be reconciled unto him
through the atonement of Christ, his Only Begotten Son, and ye may obtain a
resurrection, according to the power of the resurrection which is in Christ,
and be presented as the first-fruits of Christ unto God, having faith, and
obtained a good hope of glory in him before he manifesteth himself in the
flesh.
|
|
|
12 And now, beloved, marvel not that I tell you these
things; for why not speak of the atonement of Christ, and attain to a perfect
knowledge of him, as to attain to the knowledge of a resurrection and the
world to come?
|
|
|
13 Behold, my brethren, he that prophesieth, let him
prophesy to the understanding of men; for the Spirit speaketh the truth and
lieth not. Wherefore, it speaketh of things as they really are, and of things
as they really will be; wherefore, these things are manifested unto us
plainly, for the salvation of our souls. But behold, we are not witnesses
alone in these things; for God also spake them unto prophets of old.
|
|
|
14 But behold, the Jews were a stiffnecked people; and
they despised the words of plainness, and killed the prophets, and sought for
things that they could not understand. Wherefore, because of their blindness,
which blindness came by looking beyond the mark, they must needs fall; for
God hath taken away his plainness from them, and delivered unto them many
things which they cannot understand, because they desired it. And because
they desired it God hath done it, that they may stumble.
|
|
|
15 And now I, Jacob, am led on by the Spirit unto
prophesying; for I perceive by the workings of the Spirit which is in me,
that by the stumbling of the Jews they will reject the stone upon which they
might build and have safe foundation.
|
|
|
16 But behold, according to the scriptures, this stone
shall become the great, and the last, and the only sure foundation, upon
which the Jews can build.
|
|
|
17 And now, my beloved, how is it possible that these,
after having rejected the sure foundation, can ever build upon it, that it
may become the head of their corner?
|
|
|
18 Behold, my beloved brethren, I will unfold this mystery
unto you; if I do not, by any means, get shaken from my firmness in the
Spirit, and stumble because of my over anxiety for you.

"Create with me"
I eventually will have a full working recipe and cooking application allowing the user to search up not only what to cook but how to cook.
I eventually will have a full working weather application allowing the user either using their own location or specifying another one to see the daily and weekly forecast of the weather using a weather API.
In this application not only did I get to work with another API(aplication Programming Interface) I got to experiment with more Javascipt and high order array functions.. a.k.a list's of data.
We begin diving deeper into javascript and actually writing code that does something. I am still working on this application.
I had to design a small pop quiz application that will test your knowledge on a few random topics. Who wants to be a millionaire!?
After a few weeks of understanding HTML and CSS we had to dive into Javascript and how to functionality to a website. In this case you will be guided through a couple window prompts to generate your own unique password, just don't forget to write it down!
One of my very first projects I ever worked on with absolutly no experience writing code other than a little python that I had written here and there.

[the cutting edge ]
G'Day Developers!
Supporting old operating systems and old versions means you
have more (and often messy) code, with lots of if or switch
statements. This might be OK for you, because you wrote the
code, but down the track when someone else is maintaining it,
then there is more time/expense needed.
I believe when you realize there is a better way to do
something, then you should change it, clean code should be the
goal, however because this affects old users, and changing
interfaces at every whim also means expense for all the apps
that break, the decision isn't so easy to make.
Our views on backward compatibility starts with asking these
questions:
-
Question 1: How many apps are we going to break externally?
-
Question 2: How many apps are we going to break internally?
-
Question 3: What is the cost of providing backward
compatibility and repairing (and test) all the broken apps?
Lets look at an example:
We have a public web service
/ssw/webservices/postcode/
If we change the URL of this public Web Service, we'd have to
answer the questions as follows:
-
Answer 1: Externally - Dont know, we have some leads:
We can look at web stats and get an idea.
If an IP address enters our website at this point, it tells
us that possibly an application is using it and the user
isn't just following the links.
- Answer 2: Web site samples + Adams code demo
-
Answer 3: Can add a redirect or change the page to output a
warning Old URL. Please see www.ssw.com.au/
PostCodeWebService for new URL
Because we know that not many external clients use this
example, we decide to remove the old web service after some
time.
Just to be friendly, we would sent an email for the first
month, and then another email in the second month. After
that, just emit "This is deprecated (old)." We'll also
need to update the UDDI so people don't keep coming to our old
address.
We all wish we never need to support old code, but sometimes
the world doesn't go that way, if your answer to question 3
scares you, then you might need to provide some form of
backward compatibility or warning.

SSW Rules pages.

--- title: "Choose your own inflection point!" author: "Drew Tyre" date: '2020-04-20' output: pdf_document: default html_document: code_folding: hide word_document: default og_image: /post/covid19-choose-your-own_files/figure-html/UNMC_prediction_inf-april13.png draft: no slug: covid19-choose-your-own tags_include: - R - OPD - COVID19 categories: Research ---
I was excited to see a plot of future cases in Nebraska with prediction limits! I had questions. I couldn’t find any answers.
The first post in this series was March 13, in case you’re just joining and want to see the progression. I’m now posting the bottom line figures for each state and province on the same post that just gets updated each day.
DISCLAIMER: These unofficial results are not peer reviewed, and should not be treated as such. My goal is to learn about forecasting in real time, how simple models compare with more complex models, and even how to compare different models.1
The figure was made in R, so clearly built by someone who knows what they are doing! It comes from the UNMC COVID-19 dashboard, on the Predictive Tool Tab. I was unable to find any documentation of how the model is estimated. It does have one unique feature: you get to choose your own inflection point!
As far as I can tell, the model being used is a simple logistic curve. This “S-shaped” curve is what you get if the per capita rate of population growth decreases with increasing population size. In the exponential models I’ve been fitting, the per capita rate of growth is constant. Epidemics follow logistic curves because the rate at which susceptible people get infected decreases as the epidemic progresses. In the very simplest models this happens because there are fewer and fewer susceptible people. Most people have already had the disease and recovered (or died), so the number of infected people shrinks as well. Infections happen when a susceptible person encounters an infected person, so the rate of new infections decreases as the epidemic progresses.
The “inflection point” that you get to choose is the moment in time were the rate of new infections stops accelerating and starts decelerating. In real life, this appears as a shrinking number of new cases per day. So why is the UNMC model using a “choose your own” strategy? I think it is really hard to estimate the inflection point before the epidemic reaches the inflection point. As a result model won’t identify a good answer unless an inflection point is specified. That is what I found when I played with logistic models a few weeks ago.
These models (and the similar ones from IMHE) are being used to predict (fancy guess!) how many people will ultimately get sick during this first wave of the epidemic. But these models are forced to be symmetrical about the inflection point, so if the model is using data from before the inflection point, it fits a rapidly rising curve. But then the prediction approaches the asymptote just as quickly. Which would be great, because it means fewer sick people! But there’s no guarantee that it will actually happen that way.
It is easy to see how important the inflection point is by changing it and inspecting the change in the predicted number of cases. As of this writing, April 20th, the model predicts 2994 cases and 64 deaths by the end of May. If I change the inflection point back a week, to April 13th, the model predicts 1771 cases and 38 deaths. In addition, you can see that later points are clearly exceeding the predictions:
If I make the inflection point a week later, on April 27th, the model predicts 5135 cases and 109 deaths. Those are big swings! Looking at the data up to April 18th for Nebraska there is no sign of a slowdown in my analysis:
The simpler model I’m using can’t predict where the asymptote will be, but it can help identify when the epidemic has passed the inflection point. As of April 19 there were 1474 cases in Nebraska. The doubling time is about a week, so if our cases curve stays straight, we will have nearly 3000 cases in Nebraska by next Monday. That’s as many as the UNMC model has in the entire first wave, if the inflection point is today. Such is the unfortunate power of exponential growth.
I’m hoping reality turns out closer to the UNMC model than my model. I want those next few points dropping to the right!

GroupShare API Documentation
Introduction
This page contains links to the available resources you'll need to work with the current version of the GroupShare REST API. Through the use of the REST Web API 3rd party developers can extend the GroupShare eco-system. Your applications can integrate with GroupShare using simple HTTP methods - supporting JSON format. All the calls in this specifications are OAuth 2.0 protected resources. This means that callers must provide a so called "bearer token". This token can be obtained by issuing a POST request, to the authentication/api/1.0/login URL (see the Login section of the GroupShare Web API). The received token can be used to get access to the associated resources (all of the exposed API calls).
The API documentation is currently split into two parts:
- The GroupShare Web API
- The TM Service API
GroupShare Web API
This includes the documentation for authentication, user management, project management and terminology management. The documentation can be found in your implementation of GroupShare at [servername.domain]/documentation/api/index. For example, you can find the current version on our development test server here: https://groupsharedev.sdlproducts.com/documentation/api/index
TM Service API
This includes the documentation for Translation Memory management. The documentation can be found in your implementation of GroupShare at [servername.domain]/docs/ui/index. For example, you can find the current version on our development test server here: https://groupsharedev.sdlproducts.com/docs/ui/index
GroupShareKit
To provide an easy way to interact with the REST API above we have created the GroupShareKit which is a client library targeting .NET 4.6 and above. It currently supports two versions:
- GroupShareKit
- GroupShareKit-2017
This can be found here: https://github.com/sdl/groupsharekit.net
We have also created a sample web application using the GroupShareKit. The source code of the application is available here : https://github.com/sdl/GroupShareKit-Sample
Additional helpful resources
Video exploring the use of Swagger with the GroupShare REST API
There is also a useful video here on how to work with the REST APIs and the swagger page. It is based on working with the 2017 version of GroupShare, but the principles are the same:
GroupShare Api endpoints step by step
This wiki in the Language Developers forum on the RWS Community explains everything you need to know about working with the GroupShare API endpoints: https://community.sdl.com/developers-more/developers/language-developers/w/wiki/3395.groupshare-api-endpoints-step-by-step
GroupShare WebHooks Service
WebHooks provide a publish / subscribe model for wiring together Web APIs and services. You can subscribe to GroupShare events and get notified when that event happens through a callback. This wiki in the Language Developers forum on the RWS Community explains: https://community.sdl.com/developers-more/developers/language-developers/w/wiki/3388.groupshare-webhooks-service
Where to get further help
If you have any questions on any of the GroupShare APIs the best place to ask is in the community here: https://community.sdl.com/developers-more/developers/language-developers/f/sdk_qa

Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.
Tips on Learning to Play Tennis
You may think because you didn’t play tennis as a kid or even as a teenager, it’s too late to start now. The truth is, you can begin playing tennis at any age, and it’s great for your physical and mental health. Tennis truly is a sport you can play for a lifetime. You don't need to have a massive court, an outfit and the best racket out on the market to get great at tennis.
Three Tips on Learning to Play Tennis Later in Life
-
Proper Equipment
You don’t need a lot to begin playing tennis. You just need a racquet and some gym clothes including proper shoes. Any set of gym clothes will work for tennis, so you don’t necessarily need to spend a lot of money. Tennis requires a good amount of footwork, however, so you’ll need to make sure you have a decent pair of tennis shoes. Avoid running shoes as they do not provide the ankle support you’ll need for rapid lateral movement.
-
Use a Ball Machine
Once you know the basics of the forehand and backhand stroke, you’ll want to practice, practice, practice. A great way to improve your stroke is by renting a ball machine and simply practice returning the balls. Listen to your instructor and use the ball machine to master what you learn.
-
Play Regularly
This is key to improving in any sport or anything you want to do. Play regularly. Go to your tennis lessons and then play with a partner and practice every week. Your muscles need it for conditioning and muscle memory. Practice the skills you learn and you’ll see yourself improving week after week. A club is a great place to do this. While you’re at it, don’t forget to have fun!

Well, my birthday is almost over. Ahhh… here in germany that is. In the US, if I were there, I would still have my birthday for some time. Then again, in Japan it is already over. Hmmmm… :)
Anyway. Thank you all the people for wishing me a good birthday and also thank you to LiveJournal for their automated birthday gratulations :)
The day was very good. It started out nice at my girlfriends place where I got some very cool gifts including a very nice cake just for me :). And I did not expect the gifts, which are always the best. The backpack is something I really needed and I got some very cool pizza plates. Very very nice. /me very happy.
One of the fun things to start with was that I got a card which was for people born under my star-sign (hope that’s the right name). And it said that Monday was a good day for me (cool!) and the numbers 2 and 7 are my lucky numbers! WAY COOL! I am not into this kind of things but hey, this is just too good. And it was not a card for people born on the 2nd of July being a Monday :)
So the day continued very well and I even got a parking space directly in front of the house. This is very rare! So much for luck eh?!
The other gifts I got were also wonderful and especially mostly not something I expected.  Again I had a wonderful time with my brother and his girlfriend and later went to dinner with them a new restaurant which was also amazing.
I had some kind of very tasty chicken with a spizy-tomato-jogurt sauce. Now you had small pieces of bread, in the sauce (so all filled with sauce) and the chicken above that. Really interesting. Together with the salad it was really amazing.
Next we played Siedler, a very cool game which my brother gave me with two extensions. We started simple without the extensions though. I WON! TWICE! Well actually not twice. Just the first time I would have won I blew it by only having won if the illegal thing I did were allowed. :)
In the middle some of my friends called and said he could come to the party on Saturday.
I really have to use the last 45 minutes of this wonderful day.
Hmmm… what am I doing here? :)
Talk to you soon.

Please MAXIMIZE the browser to optimize the view of slides, charts and tooltips. Text alignment may not work with IE explorer. Use Chrome for recommendation.
About this Visualization
This visualization uses the Interactive Slideshow to tell the story of
LIFE EXPECTANCY.
Built on scenes following a template of visual consistency, with various annotations, parameters and some triggers (will be explained more in the next two slides).
More details of data cleaning information go here:
ABOUT THE DATASET (slide 5).
The four scenes follow the structure as followings:
The first scene focuses on world life expectancy from year 1960 to 2016;
The second scene focuses on the average life expectancy during year 2000 and year 2016 of each area;
The third scene focuses on the average life expectancy during the same year period of each country;
The last scene focuses on the life expectancy during the same year period of two selected countries with
largest and smallest average life expectancy.
The four charts in this visualization:
Line chart shows world life expectancy from year 1960 to year 2016.
Two Bubble charts: area bubble chart shows the average life expectancy of each area from year 2000 to year 2016
and country bubble chart shows the average life expectancy of each country during the same time period.
Bar chart shows the life expectancy of Japan and Sierra Leone from year 2000 to year 2016.
Elements of This Visualization
Scenes
There are 12 slides, including four scenes with single chart of each scene in this presentation.
Each slide can be navigated through guiding arrows in the right bottom corner.
Press Esc key at any point to get an overview of all slides.
Parameters
The main parameters of this story are country & area names, corresponding value of life expectancy and years.
Triggers
Zoom and Brush of x-axis (year) in line chart to filter data of world life expectancy,
buttons in country bubbles chart to trigger updates of visualization with new parameters of groups.
Elements of This Visualization (continued)
4. Annotations: including tooltips, legends and labels; follow a template of visual consistency.
Trends of data in both line chart and bar chart show up by clicking the "down" arrow within the slide.
Tooltips follow a template for visual consistency (see file "tooltip.js" for details):
1. Tooltips in country bubble chart with information of country name and corresponding average life expectancy
show up by moving mouse over a bubble. When a tooltip shows up, the corresponding bubble will be highlighted by
changing the stroke color to black. Tooltip disappears by moving mouse off a certain bubble.
2. Tooltips in bar chart shows up by moving mouse over a bar. When a tooltip shows up, the corresponding bar will be highlighted by
changing the filled color and changing stroke color to black. Tooltip disappears by moving mouse off a certain bar. The detailed information of tooltips in
bar chart could be found in Slide 10.
Labels:
1. Labels in area bubble chart shown in the center of each bubble with information of area name and corresponding average life expectancy.
2. Labels in both line chart and bar chart: y-axis stands for value of "Life Expectancy" and x-axis stands for "Year".
Legends:
1. Legends in country bubble chart: assign colors of blue, red, orange and green to group 1, group 2, group 3 and group 4
respectively.
2. Legends in bar chart: assign original filled colors of blue and green to country Japan and Sierra Leone respectively.
About the dataset
The dataset could be found through LIFE EXPECTANCY,
named "life expectancy at birth, total.csv" which contains all the data of each country, area and world from year 1960 to 2016 (exclude 2017 since data of 2017 are not available).
This visualization mainly talks about world life expectancy from 1960 to 2016, average life expectancy of each country and area from year 2000 to 2016.
Why chose Japan and Sierra Leone?
From the analysis of average life expectancy of each country from year 2000 to year 2016, Japan has the largest average life expectany and Sierra Leone has the
smallest average life expectancy. The last scene with bar chart shows the life expectancy, sum and the difference of life expectany of Japan & Sierra Leone from year 2000 to year 2016 (exclude 2017 since data of 2017 are not available).
I used python to generate useful data file and filter data.
Life Expectancy at birth of world from year 1960 to year 2016
Use mouse to select year range to zoom and brush.
From the chart, the life expectancy of world keeps increasing annually.
Average Life Expectancy of each Area from year 2000 to year 2016
Each bubble with different colors stands for each area, the number presents the value of average life expectancy during year 2000 and year 2016. The diameters of bubbles are proportional to the values of average
life expectancy. Colors depend on the order of "d3.schemeCategory20" with decreasing value of average life expectancy of each area.
Then the next slide presents the average life expectancy of each country from year 2000 to 2016.
Based on the data analysis, the average life expectancy of world from year 2000 to 2016 is around 71.
All the countries will be assigned to 4 different groups by the corresponding average life expectancy ordered randomly by country names.
Group 1 (color of blue with the largest bubbles) is the countries with average life expectancy in range [75, 85].
Group 2 (color of red with the second largest bubbles) is the countries with average life expectancy in range [71, 75].
Group 3 (color of orange with the third largest bubbles) is the countries with average life expectancy in range [51, 71].
Group 4 (color of green with the smallest bubbles) is the countries with average life expectancy in range [45, 51].
The diameter of each bubble is proportional to the value of average life expectancy. Tooltip of each bubble shows up when moving mouse over a circle and disappears by moving
mouse off a bubble. All countries button is set up by default.
Click By groups button to view average life expectancy from 2000 to 2016 of all countries by groups.
Clicking All countries button after clicking By groups button will show
all the bubbles ordered by group levels (from left to right are group 1, group 2, group 3, group 4). Please refresh the
page to view "All countries" by default orders (ordered randomly by country names).
Average Life Expectancy of each Country from year 2000 to 2016
Diameter of each bubble is proportional to value of average life expectancy. Move mouse over a bubble to highlight the bubble and show tooltip. The tooltip disappears
when moving mouse off a bubble. Click "By groups" buttons to visualize bubbles differently. Clicking "All groups" after viewing
bubbles by groups will show the bubbles grouped by colors (order from left to right is blue bubbles, red bubbles, orange bubbles and green bubbles).
Please refresh the page to view All countries by default orders.

From the previous slides and data analysis, Japan and Sierra Leone are
two countries with largest average life expectancy and smallest average life expectancy from year 2000 to year 2016. The bar chart shows
the life expectancy, sum and difference of life expectancy of Japan and Sierra Leone from year 2000 to year 2016.
The bottom green bars stand for life expectancy of Sierra Leone, the upper blue bars stand for Japan.
Tooltips of blue bars (life expectancy of Japan)
show the sum of the two countries of a certain year, the country name of Japan, the life expectancy in the same year, the difference of life expectancy between two
countries and year.
Tooltips of green bars show the country name of Sierra Leone, the life expectancy in the same year, the difference of life expectancy between two
countries (the same absolute number of the difference shows in tooltip of Japan, but with opposite sign) and year.
Tooltip of each bar shows up, the filled color and the stroke color of the bar change
by moving mouse over a bar. Tooltip disappears, the filled color changes back to original filled color by moving mouse off a bar.
Life Expectancy of Japan and Sierra Leone from 2000 to 2016
Move mouse over a bar to show the different highlighted colors and the tooltips. Move mouse off a bar to clear the tooltip. More details in previous slide.
From the difference values of life expectancy of Japan
and Sierra Leone from year 2000 to year 2016, the difference trends to decrease.

Simple example with four sources and iterator function
iter:JSONPath, which
extracts a list of sub-JSON documents of a JSON document, according to a
JSONPath expression. See https://github.com/json-path/JsonPath
for the JSONPath syntax specification.
- Param 1: (json): the URI of the JSON document (a URI), or the JSON object
itself (a String);
- Param 2: (jsonPath) the JSONPath query;
- Param 3 .. N : (auxJsonPath ... ) other JSONPath queries, which will be
executed over the results of the execution of jsonPath, and provide one
result each.
The following variables may be bound:
- Output 1: (string) sub-JSON document, encoded in a string literal;
- Output 2 .. N-1: result of the execution of the auxiliary JsonPath
queries on Output 1, encoded as a boolean, float, double, integer, string, as
it best fits;
- Output N: (integer) the position of the result in the list;
- Output N+1: (boolean) true if this result has a next result in the
list.
Output 2 and 3 can be used to generate RDF lists from the input, but the use
of keyword LIST( ?var )
as the object of a triple pattern covers most cases
more elegantly.

[Version 0.46 -
A general theory may also help to predict where new systems may have features qualitatively different from everything previously observed. For instance, space within modern communication and computing environments is effectively non-metric (it takes approximately the same time and effort to phone anybody in a country, or address any memory unit within a computer). This means that most space-related laws of all previous functional spaces would not apply to "digital" systems: there is no concept of premium location here, or differential rent, no "reproductive isolation" or other influence of space-induced separation on agents' communication and diversity. Also digital systems often have lower replication costs of agents than execution costs, which makes them dramatically different from all systems more essentially embedded in their physical substrates. - For humans, it's much easier to translate an article or to fix an appliance than to transfer the necessary skills to another person. For a computer it is just copying a program.
Together, the above features create a foundation for system design that is dramatically different from all natural and human agglomerations, in terms of agent specialization, diversity, and deployment. I would envision the future intelligence as a collection of highly specialized tools, with high-bandwidth interconnections, with "personalities", or complex problem solvers ("achievers", "goal engines", "research tools", "development threads") consisting of limited contractual relations between multiple problem-solving, planning, perceiving, and acting entities, that can at the same time be employed in many other similar relations. So the entities may use the same "body parts" on a cooperative or time-sharing basis.
While the economy provides its agents with accurate estimates of generic values of typical goods and services, it has little to offer to each individual agent in their attempts to estimate the utility of a certain product for their particular needs, or offer any other personalized or situational advice. This kind of knowledge is usually obtained by the economic agents in about the same way they discovered average social values of common products and services in pre-economic times: personal experience with the environment and direct communication with other agents. There are no quantitative instruments available for automated processing for this purpose.
This is understandable: comprehensive detailed data about each agent's behavior so far has not been available in a usable form, communication and computational tools necessary for processing this data have not been adequate, transaction costs have been too high, etc. All these obstacles are now being removed in many systems.
With these tools in place, there appears a foundation for "a second signaling mechanism" in an economic system: together with conventional aggregate indicators of average costs of resources and services and their expectations, the new crop of signaling instruments may deliver suggestions of expected value that particular agents may derive in their individual situations from such resources or services. Then agents can be better equipped to optimize their behavior by using all available knowledge for comparing personal and global costs, risks, and utilities.
Systems carrying representations of situational knowledge ("hyper-economies", or "super-economies") may be implemented in both completely automated environments and those involving humans (e.g., they could assist people in selection of things most appropriate for their tastes and situations, from recommending movies they want to see, to tools that would satisfy their needs at the best price to choosing diets and insurance plans for their own goals and conditions).
There is some analogy here with the notion of "psychohistory" suggested by Isaac Asimov in his Foundation series, except that instead of using detailed representations of social processes for long-term prediction of future events (which is hardly possible with a still very imperfect model of a huge chaotic system), I suggest a more modest goal of using them for richer local modelling and adaptive control. The only advantage here is that this modest goal seems actually achievable.
I am trying to approach this topic both theoretically and experimentally.
Theoretical part consists of considerations of how the new signaling systems may change our familiar economic notions, such as capital, interest, efficiency, liquidity, inflation, emission rights, secondary and derivative instruments. Some of these features will remain relatively unchanged but become more liquid (faster distribution and lower transaction costs) and more efficient. Other parameters may turn from scalar to vector or a more complex structure (e.g., augmentation of the numerical representation of value of an object with a matrix of its utilities for various purposes as estimated by different agents. Some features, such as non-scalar "situational/detail derivatives" for assessing values and risks of, and balancing among, particular utilities will be entirely new.
Similar changes will happen with the concepts from social and ecological fields. Communities do not have to be local anymore, they may have variable/adaptable geometries, relations between managing and performing agencies will be redefined, new control structures and dynamic patterns arise, etc.
On the experimental side, we are working on simple versions of such systems in Internet environments, where the data is already available, and the results seem of direct practical use. Recently, we created a Hyper-Economy Development Group (HEDG) for modelling such systems. The group is open to interested researchers.
Among the first applications of this approach I envision large automated collaborative filtering projects, link exchange programs and targeted advertising, balancing flows of information in accordance with diverse and dynamic interests of creators, consumers, providers, and sponsors of the Web content.
My hope is that eventually such hyper-economic schemes will develop to store and process increasingly complex representations of agent interests and utilities, and have a great variety of competing intelligent algorithms for optimizing system processes, thus turning into a hybrid of an economic self-regulatory mechanism, complex multifaceted community, and distributed artificial intelligence, with secondary data representation and signaling mechanisms forming emerging self-awareness of the new systems.
It seems noteworthy that in these constructs, as well as in conventional economy, the meta-signaling [generalized/abstract in relation to actual "field agents"] level is represented in terms of signal currents in the semantic space rather than crisp symbolic constructs. We can interpret this as a sign that the connectionist approach is natural for a fetal stage of any system intelligence. Or - better - that a combination of symbolic processing with signal flow patterns will extend the human balance of symbolic reasoning and intuition to further levels of intelligence.

Founded in 1952 by Arthur Landon, an English businessman who travelled the world in search of the perfect balance of comfort, personality, and convenience.
Nestled between a yoga studio and a bakery, on a quaint street in this community-centered neighborhood, is the 40-room, modern-themed, Landon Hotel, with a state of the art massage studio.
The Landon Massage Center is an internationally renowned center for massage therapy and holistic healing. Guests of the Bernal Heights Landon are entitled to a free massage during their stay.
The Bernal Heights Landon also functions as a gathering place for many of the community’s activities and calls to activism. It seems that no one can leave the hotel untouched by the sense of community, peace, and well-being.

bigIntegerToBytes
public static byte[] bigIntegerToBytes(java.math.BigInteger b, int numBytes)
The regular
BigInteger.toByteArray()
includes the sign bit of the number and might result in an extra byte addition. This method removes this extra byte.Assuming only positive numbers, it's possible to discriminate if an extra byte is added by checking if the first element of the array is 0 (0000_0000). Due to the minimal representation provided by BigInteger, it means that the bit sign is the least significant bit 0000_0000 . Otherwise the representation is not minimal. For example, if the sign bit is 0000_0000, then the representation is not minimal due to the rightmost zero.
- Parameters:
b

- the desired size of the resulting byte array- Returns:
- numBytes byte long array.

-
decodeCompactBits
public static java.math.BigInteger decodeCompactBits(long compact)
The "compact" format is a representation of a whole number N using an unsigned 32 bit number similar to a floating point format. The most significant 8 bits are the unsigned exponent of base 256. This exponent can be thought of as "number of bytes of N". The lower 23 bits are the mantissa. Bit number 24 (0x800000) represents the sign of N. Therefore, N = (-1^sign) * mantissa * 256^(exponent-3).
Satoshi's original implementation used BN_bn2mpi() and BN_mpi2bn(). MPI uses the most significant bit of the first byte as sign. Thus 0x1234560000 is compact 0x05123456 and 0xc0de000000 is compact 0x0600c0de. Compact 0x05c0de00 would be -0x40de000000.
Bitcoin only uses this "compact" format for encoding difficulty targets, which are unsigned 256bit quantities. Thus, all the complexities of the sign bit and using base 256 are probably an implementation accident.

Define new register names using the following syntax:
REG = reg_name [offset space_name] byte_size [SEQ first last obj_inc [inc]]
Table 3-4. Variable Descriptions
|
Variable Name |
Description |
|---|---|
|
reg_name |
Identifier giving the name of the register being defined. If the name begins with ‘$’, it defines a “debugger local” register and the offset and the space_name are omitted. |
|
offset |
Decimal number giving the register’s byte offset within the specified space. For real register spaces, the offset is the register number times the register size. For memory spaces, the offset is the byte address. |
|
space_name |
One of the keywords from the following list giving the register file or memory space for the register. See Table 3-6 and Table 3-7. |
|
byte_size |
Size of the register in bytes (1, 2, 4. or 8). |
|
Decimal number giving the first value to append to reg_name to form a sequence of names. Sequences make it easy to represent a consecutive set of like-named registers (for example, r0..r31). |
|
|
last |
The last number in the sequence (see first). |
|
obj_inc |
Decimal number giving the "stride". It is normally 1, but can be set to a higher value when the registers in the sequence are actually addressed as every Nth register in the space. For each register in the sequence, the amount added to the offset to form the address is the register sequence number * byte_size. |
|
inc |
Decimal number giving the amount by which to increment the register number for each name in the sequence. If not specified, the default is 1. |
Table 3-4 shows the definitions for the variable definition.
For example: You want a sequence of four 8 bit registers mapped to physical memory at 0, with each register in the low byte of successive machine words (32 bits). To name these registers z1, z3, z5, etc., the definition syntax is:
REG=z 0x0 MEMORY_P 1 SEQ 1 7 4 2
Register Field Definition File Format
Registers can also be broken down into displayable fields. Any previously defined register or register sequence can be set up as field encoded. If a field breakdown is provided for a register sequence, the fields apply to every register in the sequence. Fields of more than one bit are displayed as field_name=hexadecimal_value. One bit fields are displayed as an uppercase or lowercase field_name where uppercase means a TRUE or 1 value.
REG_FIELD = reg_name field_spec [, field_spec]
Table 3-5 shows the REG_FIELD variable descriptions.
Additional Notes:
INCLUDE “filename”
Table 3-5. REG_FIELD Variables
The following example demonstrates a definition for some memory-mapped registers (common in hardware designs).
// Define a register named 'dev_a_ctrl' and associate its address, space, and size
REG = dev_a_ctrl 0xFF00A000 PHYSICAL 4
// Define the names and bit positions of fields within the 'dev_a_ctrl' register
REG_FIELD = dev_a_ctrl status 2 0, lock 3 3
// Define additional registers
REG = dev_a_data1 0xFF00A004 MEMORY 4
REG = dev_a_data2 0xFF00A008 MEMORY 4
// <eof>
