Nollywood’ll be compared to Hollywood in two years –Scott Roberts
by Olajide SamuelOlajide Samuel
Actor, Scott Roberts, has revealed that he sometimes gets weird messages from fans. In an interview with Saturday Beats, he said a fan once said she would love to kiss him.
“I manage my female fans. Sometimes I act like I don’t see some of these messages they send to me, and if it’s not so annoying, I simply say ‘hello’.
“A fan once sent me a message, saying, ‘I would love to kiss you’. Some of them say they would love to spend time with me. It makes me laugh.”
Asked why he plays more of lover boy roles, Roberts said: “I don’t want to believe I have been typecast as a lover boy because there are a lot of movies I have appeared in that have nothing to with playing lover boy roles.
Speaking further, he denied taking a break from acting.
“I didn’t take a break from acting; I have been doing a lot of other things. I have a movie that just came out titled, ‘The Good’. Sola Sobowale, Alex Usifo and others starred in the movie.
Commenting on the growth of Nollywood, the actor said, “The movie industry is actually better now. Between now and the next two years, we can actually be compared to Hollywood.”

Scotland's Liam Palmer out for revenge against Kazakhstan
Scotland right-back Liam Palmer admits revenge is on his mind as he prepares to face Kazakhstan on Tuesday.
Palmer made his international debut in the 3-0 defeat in Nur-Sultan which opened Scotland's European Championship qualification group.
They close their Group I campaign against Kazakhstan on Tuesday night at Hampden with a different manager in place after Steve Clarke replaced Alex McLeish two games in.
Palmer agrees with Clarke that Scotland need to look forward to March's play-off campaign and beating Kazakhstan to seal third place and a hat-trick of wins would help with confidence and momentum.
But after waiting seven months for his second cap, Palmer is also looking to exorcise some demons from his debut.
Palmer, who made his fourth Scotland appearance in Saturday's win over Cyprus, told the PA news agency: "The boys who didn't play on Saturday, if they get a chance to play on Tuesday they will be keen to show what they can do and everyone is trying to stake a claim for, hopefully, two big games in March.
"Everyone is pushing towards that. It would be massive, not just for me obviously, but for everyone in the country, fans, if we can get there.
"But it's an old cliche, one game at a time, and just build from what is a winnable game and a bit of revenge for some of us who were out there at the start of the campaign.
"It's another element we will be looking to address."

Trains logistic regression model by discretizing continuous variables via gradient boosting approach. The proposed method tries to achieve a tradeoff between interpretation and prediction accuracy for logistic regression by discretizing the continuous variables. The variable binning is accomplished in a supervised fashion. The model trained by this package is still a single logistic regression model, but not a sequence of logistic regression models. The fitted model object returned from the model training consists of two tables. One table is used to give the boundaries of bins for each continuous variable as well as the corresponding coefficients, and the other one is used for discrete variables. This package can also be used for binning continuous variables for other statistical analysis.

10.8 Richer-Text I/O
The tools we have covered so far
support the minimal subset of text I/O functionality that all
platforms supply. Most platforms also offer richer-text I/O
capabilities, such as responding to single keypresses (not just to
entire lines of text) and showing text in any spot of the terminal
(not just sequentially).
Python extensions and core Python modules let you access
platform-specific functionality. Unfortunately, various platforms
expose this functionality in different ways. To develop
cross-platform Python programs with rich-text I/O functionality, you
may need to wrap different modules uniformly, importing
platform-specific modules conditionally (usually with the
try/except idiom covered in
Chapter 6).
10.8.1 The readline Module
The readline module
wraps the GNU Readline Library. Readline lets the user edit text
lines during interactive input, and also recall previous lines for
further editing and re-entry. GNU Readline is widely installed on
Unix-like platforms, and is available at http://cnswww.cns.cwru.edu/~chet/readline/rltop.html.
A Windows port (http://starship.python.net/crew/kernr/) is
available, but not widely deployed. Chris
Gonnerman's module, Alternative Readline for
Windows, implements a subset of Python's standard
readline module (using a small dedicated
.pyd file instead of GNU Readline) and can be
freely downloaded from http://newcenturycomputers.net/projects/readline.html.
When either readline module is loaded, Python uses
Readline for all line-oriented input, such as
raw_input. The interactive Python interpreter
always tries loading readline to enable line
editing and recall for interactive sessions. You can call functions
supplied by module readline to control advanced
functionality, particularly the history functionality for recalling
lines entered in previous sessions, and the completion functionality
for context-sensitive completion of the word being entered. See
http://cnswww.cns.cwru.edu/~chet/readline/rltop.html#Documentation
for GNU Readline documentation, with details on configuration
commands. Alternative Readline also supports history, but the
completion-related functions it supplies are dummy ones: these
functions don't perform any operation, and exist
only for compatibility with GNU Readline.
Returns the number of lines of history that are saved to the history
file. When the returned value is less than 0, all
lines in the history are saved.
parse_and_bind(readline_cmd)
|
|
Gives Readline a configuration command. To let the user hit Tab to
request completion, call parse_and_bind('tab:
complete'). See the GNU Readline documentation for
other useful values of readline_cmd.
read_history_file(filename='~/.history')
|
|
Loads history lines from the text file whose name or path is
filename.
read_init_file(filename=None)
|
|
Makes Readline load a text file, where each line is a configuration
command. When filename is
None, Readline loads the same file as last time.
Sets the completion function. When f is
None, Readline disables completion. Otherwise,
when the user enters a partial word start
and then hits Tab, Readline calls
f(start,i),
where i is an int,
initially 0. f returns
the ith possible word that begins with
start, or None when
there are no more. Readline calls f
repeatedly, with i set to
0, 1, 2,
..., until f returns
None.
Sets the number of lines of history that are saved to the history
file. When x is less than
0, all lines in the history are saved.
write_history_file(filename='~/.history')
|
|
Saves history lines to the text file whose name or path is
filename.
An example of a completion
function is in module rlcompleter. In an
interactive interpreter session (or, more practically, in the startup
file that the interpreter runs at the start of each interactive
session, as covered in Chapter 3), you can enter:
import readline, rlcompleter
readline.parse_and_bind('tab: complete')
Now, for the rest of this interactive session, you can hit Tab during
line editing and get completion for global names and object
attributes.
10.8.2 Console I/O
Terminals today are most often text windows
on a graphical screen. You may also use a true terminal or the
console (main screen) of a personal computer in text mode. All kinds
of terminals in use today support advanced text I/O functionality,
but you access this functionality in platform-dependent ways. The
curses package works only on Unix-like platforms
(there are persistent rumors of Windows ports of it, but
I've never found a working one). Modules
msvcrt, WConio, and
Console work only on Windows.
<IP_ADDRESS> The curses package
The traditional Unix approach to
advanced terminal I/O is named curses, for
obscure historical reasons. The Python package
curses affords reasonably simple use, but still
lets you exert detailed if control required. I cover a small subset
of curses, enough to let you write programs with
rich text I/O functionality. See also Eric Raymond's
tutorial Curses Programming with Python, available at
http://py-howto.sourceforge.net/curses/curses.html,
for more information. Whenever I mention the screen in this section,
I mean the screen of the terminal (for example, the text window of a
terminal-emulator program).
The simplest and most effective way to use curses
is through the curses.wrapper module, which
supplies a single function.
Performs curses initialization, calls
func(stdscr,*args),
performs curses finalization (setting the terminal
back to normal behavior), and finally returns
func's result. The first
argument that wrapper passes to
func is stdscr, an
object of type curses.Window that represents the
whole terminal screen. wrapper ensures that the
terminal is set back to normal behavior, whether
func terminates normally or by propagating
an exception.
func should be a function that performs
all the tasks in your program that may need curses
functionality. In other words, func
normally contains (or more commonly calls, directly or indirectly,
functions containing) all of your program's
functionality, save perhaps for some non-interactive initialization
and/or finalization tasks.
curses models text and background colors of
characters as character attributes. Colors available on the terminal
are numbered from 0 to
curses.COLORS. Function
color_content takes a color number
n as its argument, and returns a tuple
(r,g,b)
of integers between 0 and 1000
giving the amount of each primary color in
n. Function color_pair
takes a color number n as its argument,
and returns an attribute code that you can pass to various methods of
a curses.Window object in order to display text in
that color.
curses lets you create multiple instances of type
curses.Window, each corresponding to a rectangle
on the screen. You can also create exotic variants, such as instances
of Panel, which are polymorphic with
Window but not tied to a fixed screen rectangle.
You do not need such advanced functionality in simple
curses programs: just use the
Window object stdscr that
curses.wrapper gives you. Call
w.refresh( ) to ensure
that changes made to any Window instance
w, including stdscr,
show up on screen. curses can buffer the changes
until you call refresh. An instance
w of Window supplies,
among many others, the following frequently used
methods.
w.addstr([y,x,]str[,attr])
|
|
Puts the characters in string
str, with attribute
attr, on w at
the given coordinates
(x,y),
overwriting any previous contents. All curses
functions and methods accept coordinate arguments in reverse order,
with y (the row number) before
x (the column number). If you omit
y,x,
addstr uses
w's current cursor
coordinates. If you omit attr,
addstr uses
w's current default
attribute. In any case, addstr, when done adding
the string, sets w's
current cursor coordinates to the end of the string it has added.
w.clrtobot( )
w.clrtoeol( )
|
|
clrtoeol writes blanks from
w's current cursor
coordinates to the end of the line. clrtobot, in
addition, also blanks all lines lower down on the screen.
Deletes one character from w at the given
coordinates
(x,y).
If you omit the
y,x
arguments, delch uses
w's current cursor
coordinates. In any case, delch does not change
w's current cursor
coordinates. All the following characters in line
y, if any, shift left by one.
Deletes from w the entire line at
w's current cursor
coordinates, and scrolls up by one line all lines lower down on the
screen.
Writes spaces to the entire terminal screen.
Returns an integer c corresponding to a
user keystroke. c between
0 and 255 represents an
ordinary character, while c greater than
255 represents a special key.
curses supplies names for special keys, so you can
test c for equality with such readable
constants as curses.KEY_HOME (the Home special
key), curses.KEY_LEFT (the left-arrow special
key), and so on. The list of all curses
special-key names (about 100 of them) is in Python's
free documentation, specifically, in the Python
Library Reference, Section
6.13.3 Constants, for
current versions of Python. If you have set window
w to no-delay mode by calling
w.nodelay(True),
w.getch raises an
exception if no keystroke is ready. By default, however,
w.getch waits until the
user hits a key.
Returns w's current
cursor coordinates as a tuple
(y,x).
w.insstr([y,x,]str[,attr])
|
|
Inserts the characters in string str, with
attribute attr, on
w at the given coordinates
(x,y),
shifting the rest of line rightwards. Any characters that shift
beyond the end of line are dropped. If you omit
y,x,
insstr uses
w's current cursor
coordinates. If you omit attr,
insstr uses
w's current default
attribute. In any case, when done inserting the string,
insstr sets
w's current cursor
coordinates to the first character of the string it has inserted.
Moves w's cursor to the
given coordinates
(x,y).
Sets w to no-delay mode when
flag is true, resets
w back to normal mode when
flag is false. No-delay mode affects
method w.getch.
Updates window w on-screen with all
changes the program has effected on w.
The curses.textpad module supplies the
Textpad class, which lets you support advanced
input.
Creates and returns an instance t of class
Textpad that wraps the curses
window instance window. Instance
t has one frequently used method:
- t.edit( )
-
Lets the user perform interactive editing on the contents of the
window instance that t wraps. The editing
session supports simple Emacs-like key bindings: normal characters
overwrite the window's previous contents, arrow keys
move the cursor, Ctrl-H deletes the character to the
cursor's left. When the user hits Ctrl-G, the
editing session ends, and edit returns the
window's contents as a single string, with newlines
as line separators.
<IP_ADDRESS> The msvcrt module
The msvcrt module,
available only on Windows, supplies functions that let Python
programs access a few proprietary extras supplied by the Microsoft
Visual C++'s runtime library
msvcrt.dll. Some msvcrt
functions let you read user input character by character, rather than
reading a full line at a time.
Reads and returns one character from keyboard input, waiting if no
character is yet available for reading. getche
also echoes the character to screen (if printable), while
getch doesn't. When the user
presses a special key (arrows, function keys, etc.),
it's seen as two characters: first a
chr(0) or chr(224), then a
second character that, together with the first one, defines what
special key the user pressed. Here's how to find out
what getch returns for any key:
import msvcrt
print "press z to exit, or any other key to see code"
while 1:
c = msvcrt.getch( )
if c = = 'z': break
print "%d (%r)" % (c, c)
Returns True when a character is available for
reading (getch, if called, would return
immediately), otherwise False
(getch, if called, would wait).
Ungets character c: the next call to
getch or getche returns
c. It's an error to call
ungetch twice without intervening calls to
getch or getche.
<IP_ADDRESS> The WConio and Console modules
Two Windows-specific extension modules
supply single-character keyboard input (like
msvcrt) and the ability to paint characters in
specified positions of the text screen. Chris
Gonnerman's Windows Console I/O module is small,
simple, and easy to use. Module WConio can be
freely downloaded from http://newcenturycomputers.net/projects/wconio.html.
Fredrik Lundh's Console module is very complete and
functionally rich. Module Console can be freely
downloaded from http://www.effbot.org/efflib/console/.

Welcome to Torba's website.
En Espaņol In Italiano Em portugęs In Russian
Torba is a small dynamic tiling window manager for X11. It tries to stay out of the way so that valuable screen real estate can be used for much more important stuff. It has sane defaults and does not require one to learn a language to do any configuration. It was written by hackers for hackers and it strives to be small, compact and fast.
It was largely inspired by xmonad and dwm. Both are fine products but suffer from things like: crazy-unportable-language-syndrome, silly defaults, asymmetrical window layout, "how hard can it be?" and good old NIH. Nevertheless dwm was a phenomenal resource and many good ideas and code was borrowed from it. On the other hand xmonad has great defaults, key bindings and xinerama support but is crippled by not being written in C.
Torba is a beautiful pearl!
For it too, was created by grinding irritation.
Nothing is a bigger waste of time than moving windows around until they are the
right size-ish or having just about any relevant key combination being eaten
for some task one never needs.
The path of agony is too long to quote and in classical
OpenBSD
fashion (put up, or hack up) a brand new window manager was whooped up to serve
no other purpose than to obey its masters.
It was written by Marco Peereboom, Ryan Thomas McBride & Darrin Chandler and it
is released under the ISC
license.
Patches can be accepted provided they are ISC licensed as well.
Following are a few screenshots of torba in action.
Horizontal stack with gvim &Firefox.
Vertical stack with floater and extra window in master area.

The role of women, she said, is a much deeper issue. "I think wherever you look in the world, you see a field or an endeavor that's not got women in it. You can ask yourself: Why aren't there women there? And the answer is always the same: It's because women aren't welcome."

HOW Quorum managed to tumble out of the Psyche without upsetting her is a mystery, but he did it somehow. Seeing that he was easily making his way to the land, Worth continued on his course to the Transit, which he reached a minute later. The moment he stepped abroad, Sumner threw his arms about the boy with what was intended for a joyful hug. Worth returned it with interest. For a few seconds the two staggered about the deck in what looked decidedly like a wrestling match to the amused spectators of the scene, who had been attracted from below by Sumner’s shout. Finally they tripped and rolled with a crash into the cockpit, where they scrambled to their feet, greeted by shouts of laughter from Lieutenant Carey and Ensign Sloe, while even the men forward were chuckling with ill-suppressed mirth.
Had Sumner and Worth been a few years older, they would probably have expressed their joy over this happy and unexpected meeting with a cordial handshake, and a few inquiries after each other’s welfare during their separation. That would have been a man’s way. Happily, all boys are not men, nor are their ways men’s ways. Any genuine boy will understand that nothing short of a wrestling match would have served to express the joy with which these two young hearts were relieved of the load of anxiety that had weighed so heavily upon them during the past three days.
“But how did you know the canoes were out at the light, Worth?” inquired Sumner, after the first boisterous greeting was over. “Excuse me! Let me introduce you to Lieutenant Carey and Ensign Sloe. And how did you get there? And how did you know that we were here?” exclaimed Sumner, in a breath, as soon as he had regained his feet.
“The keeper told us,” answered Worth, shaking hands with those to whom he had just been introduced. “And I didn’t know you were here. How did you get here, and what became of the raft? Did you ever see anything so absurd as Quorum? I don’t believe he has opened his eyes since we left the light, and I actually thought he was turning white, he was so scared. Oh, Sumner, I never was so happy in my life!”
“Nor I,” answered Sumner; “and if I ever leave you again, you young scamp, before delivering you safe and sound to your lawful guardians, you’ll know it.”
“And you may be mighty sure I won’t be left again,” answered Worth. “No, siree! From this time on, you’ll think I’m your shadow, I’ll stick to you so close.”
By this time Quorum had been brought aboard, and Sumner, shaking hands with him, gravely congratulated him upon having formed the habit of taking a plunge bath before breakfast. With a reproachful look at the lad, and without deigning to reply to his banter, Quorum turned away and dived into the little forward galley. Here he quickly made himself at home, and all the time he was drying by the galley stove he could be heard entertaining the colored cook of the Transit with a thrilling description of his recent voyage in “dat an tickly nutshell.  I tell yo’, chile, hit’s er ’sperience sich as I don’t want no mo’ ob in all my sailin’.”
Around the breakfast table in the tiny after saloon Sumner and Worth were comparing experiences and discussing their plans for the future.
“I tell you what it is, Sumner,” exclaimed Worth “I don’t know about cruising any farther up this reef, where we are likely at any time to be seized and carried off to sea by some Jew-fish or other marine monster. Seems to me it’s taking a big risk.”
“Then why not come with us through the ’Glades?” laughed Lieutenant Carey. “There aren’t any Jew-fish there. It will be almost the same as cruising on dry land all the way, and we’ll bring you out at Cape Florida, the very point you are aiming for.”
“I think that would be fine,” answered Worth, who had no more idea of the nature of the Everglades than he had of the moon. “What do you say, Sumner?”
“It’s the very thing I should most love to do,” replied Sumner.
“Then you will go with us?” asked the Lieutenant.
“Yes, sir, we will,” answered both the boys.
“Good! That settles it. Now do you suppose we can persuade your old darkey to go along as cook? I think you said he was a good one, Sumner?”
“Indeed he is!” exclaimed Worth; “the very best I ever knew Oh yes, we must have Quorum along by all means.”
When the plan was laid before him, Quorum shook his head doubtfully, and said:
“I allus hear dem Ebberglades is a ter’ble place. Dey’s full ob lions an’ tigers, sayin’ nuffin’ ob wild Injuns an’ cannonballs “ (probably Quorum meant cannibals). “But ef dem two chilluns boun’ ter go, I spec’ ole Quor’m hab ter go ’long ter look after um, an’ see dat dey’s kep’ outen danger. Hit’s er mighty owdacious undertaking fer de ole man; but dish yere er peart looking wessel, an’ maybe she take us troo all right.”
“But we are not going in this vessel,” laughed Sumner. “We couldn’t take her through the ’Glades.”
“How yo go, den?” asked the Negro, looking up quickly. “Not in them tickly li’l’ cooners?”
“Yes, some of us will go in the canoes, but you will have a much larger boat; one that you can’t possibly upset.”
“When I see him, den I tell yo’ ef I er gwine.” And this was the only promise that Quorum could be induced to give.
“Very well,” said Lieutenant Carey, when this was reported to him; “we will rig up the cruisers, and let Quorum sail one of them in to Lignum Vitae. One of the men shall take the other, you two will sail your own canoes, and I will sail mine, while Mr. Sloe shall follow with the Transit. When Mr. Haines sees us coming he’ll think he is looking at a regatta of the Reef Yacht Club.”
This plan suited the boys perfectly, and the next two hours were spent in getting all the boats into the water, overhauling sails, spars, etc. When Quorum saw the Barnegat cruiser that was assigned to him, he declared, “Hit done look like er punkin seed, an’ I don’t beliebe hit fit fer sailin’ nohow.” It was only with the greatest difficulty that he could be persuaded to try the strange looking craft. When he finally did so, his eyes opened wide with astonishment at her speed and stiffness, and the ease with which she was handled.
Each of the cruisers carried a large sprit sail, and was fitted with a pair of oars. They were provided with centerboards, were fair sailers, easy to row, practically non-capsizable, and capable of carrying heavy loads without materially increasing their draught.
Quorum was a good sailor, and as soon as he became somewhat accustomed to his craft he began to handle her in a way that showed an appreciation of her qualities. When he shot ahead, after a little brush with the other cruiser, the Melon Seed — as he termed her — his black face fairly beamed with delight.
“Your man is as tickled with that boat as a child with a new toy,” remarked Lieutenant Carey to Sumner, “and I guess there is no doubt now but what he will go with us.”
The Lieutenant’s open paddling canoe was fitted with a leg-of-mutton sail, but no centerboard. Thus the sail was only available for running before the wind, which on this occasion happened to be fair. The three canoes and the two cruisers, starting on their race to Lignum Vitae, formed a very pretty sight. As they were followed by the Transit, and by the schooner that had carried Worth and Quorum to Indian Key, which came along on her return trip just then, it is no wonder that Mr. Haines regarded the approaching fleet with astonishment.
The race was won by Sumner in the Psyche, with Quorum in his Punkin Seed, and wildly excited, close behind. The other three were well bunched, and the two schooners were worked under foresails only, to keep from running them down.
All hands were made heartily welcome by the proprietor of Lignum Vitae, who was made happy by the information that they proposed to stay there that night. On hearing this he immediately began to plan a grand dinner to which everybody was invited, and an entertainment for the evening. He and Lieutenant Carey spent the afternoon in arranging for the entertainment, the four cooks, with Quorum at their head, spent it in preparing a most elaborate dinner, and the others spent it fishing and sailing match races between the various small boats. As the hours flew busily and happily by, Sumner and Worth wondered how they could ever have felt wretched and forlorn in such a pleasant place.
The dinner, which was served shortly before sunset, was a veritable feast. On its bill of fare appeared oysters, green turtle soup, fish chowder, turtle steaks, baked kingfish, stewed ducks, roasted ’possum, a variety of canned vegetables, an immense plum duff, canned fruits, crackers, cheese, and coffee; while the whole was seasoned with the sauce of hearty appetites and capital digestions. It was a substantial meal, as well as a merry one, and it gave Worth Manton a new insight into the possibilities of life on the Florida Keys.
By hard work Mr. Haines had succeeded in raising the frame of the little one-story house that he intended to occupy, and in getting the floor laid. This was to be the scene of the entertainment, and an hour or so after dinner all hands were collected here. Several large bonfires shed a cheerful light on the circle of expectant faces, and cast wavering shadows over the platform.
The first number on the program was an overture by the Lignum Vitae Band, which consisted of Mr. Haines’s banjo, Lieutenant Carey’s guitar, Ensign Sloe’s violin, and a flute played by one of the Transit’s men. Then Worth danced a clog, and was received with immense applause. He was followed by Sumner, who performed a number of sleight-of-hand tricks that drew forth exclamations of astonishment from the Negroes. A mouth-organ quartet by four of the Negro hands, was followed by Mr. Haines’s banjo solo. This was of such an inspiring character that all the Negroes patted time to it, and finally Quorum sprang upon the platform and, with his beloved pipe still held tightly between his teeth, began to shuffle a breakdown in such a comical manner that it was received with tumultuous applause and roars of laughter. Solo and chorus singing followed, and the entertainment wound up with the singing of “Annie Laurie” by a quartet of sailors.
Both Sumner and Worth were certain that they had never passed a more enjoyable evening, and were almost sorry that they had promised to leave there and start for the Everglades on the following morning.


Karuna - A community solution to ensure reliable resource allocation in the fight against Covid19
To fight against the recent outbreak of covid19 cases and the lack of resources in India, we are launching a decentralized web app, Karuna, for crowdsourcing information and providing real time updates of beds, oxygen and hospital supplies in India. Citizens of each city will have access to real-time information about resources close to them, as well as a communication platforms to reach out to doctors and hospitals for a streamlined approach to resource allocation. Surveys integrated in the app can be filled optionally by patients and hospitals to have an easy to use and reliable information database where people take a stand in helping each other. This is a volunteer effort powered by the PathCheck foundation.
For the hospitals and the general population who want a decentralized platform to know where resources are allocated, to reach out to other hospitals and administration and to share information about hospital beds, oxygen, food and other resources, the PathCheck India Karuna system is a web platform that will allow for constructive interaction between hospital administration, doctors and the population while remaining easy to use for all parties. Crowdsourcing using integrated surveys, trackers with real-time positioning of hospital resources available and communications channels will be provided for a reliable and accurate optimization of resource allocation.
Hospitals, doctors and the general population come together in our Karuna app in a community effort to collaborate on:
- Crowdsourcing patient recovery and treatment plan in a privacy-preserving manner for covid19 recovered patients.
- Have access to hospitals' integrated oxygen and inventory mapping
- Early detection and Risk stratification
- Variant tracker and super spreader tracking of the new variant
- Ending Misinformation about Covid19
Features, Crowdsourcing and More
- Surveys: Secure, Anonymous and Privacy-centered crowdsourcing options to help share important information about resources and get accurate predictions of covid19 cases spikes in the future.
- Resources: Easily get access to inventory such as beds, oxygen, plasma and more from hospitals near you with a mapped interface of availabilities next to you at all time.
- Communication and support: Get access to real time communication channels with hospitals, health officials and covid survivor forces to get verified leads on the resources and help you need in real-time.

Many of the irrational and transcendental functions are multiply defined in the complex domain; for example, there are in general an infinite number of complex values for the logarithm function. In each such case, a principal value must be chosen for the function to return. In general, such values cannot be chosen so as to make the range continuous; lines in the domain called branch cuts must be defined, which in turn define the discontinuities in the range. Common Lisp defines the branch cuts, principal values, and boundary conditions for the complex functions following ``Principal Values and Branch Cuts in Complex APL.'' The branch cut rules that apply to each function are located with the description of that function.
The next figure lists the identities that are obeyed throughout the applicable portion of the complex domain, even on the branch cuts:
sin i z = i sinh z sinh i z = i sin z arctan i z = i arctanh z cos i z = cosh z cosh i z = cos z arcsinh i z = i arcsin z tan i z = i tanh z arcsin i z = i arcsinh z arctanh i z = i arctan z

The quadrant numbers referred to in the discussions of branch cuts are as illustrated in the next figure.

JavaScript Introduction
* * *
A bit of context
JavaScript is a scripting language that is used primarily for Web Development.
It's most valuable feature is it's ability to dynamically insert content into HTML files, although it is capable of much more.
The IDE that I would strongly reccommend using is Visual Studio Code, it has many packages and user friendly features that just make life much easier when coding in JS.
In order to get an understanding of how it works I will walk through a simple JS project
This website provides a trivia game where the user enters keys on the keyboard to answer. It has 5 questions then displays the results at the end.
questions.html
This is all of the HTML in the file
You can scroll through this textarea, go ahead and copy and paste this into a file named "questions.html" in Visual Studio Code
Pay attention to two the paragraph tags in the body and their IDs
Adding JavaScript
- In order to dynamically insert content into this otherwise static HTML file we must add tags at the end of the body of the HTML file. Our JavaScript will go in between these script tags. Note: it is also possible to keep a seperate JavaScript file and link the HTML file to that serpate file by typing
Objects/ Arrays in JS
In order to store the questions with their correct answers, we must create an array of objects.
Each object will have 2 key values "q" and "a" (representing question and answer)
In order to create a variable in JS we type the 'var' keyword followed by the name of the variable
Unlike C and java, we don't need to specify the datatype
Here we have created an array of 5 objects, we will one by one insert the value of the "q" keys into the paragraph with the id 'question'
We also need to create variables to store the values of the user's current score, and the question that the user is currenly on.
We do this just like how we created the array:
Now we need to create a function to display the question to the user
Ok, there is a lot going on in there so let's break it down
First, we define the function with the name renderQuestion which takes in no parameters by typing:
function renderQuestion(){}
The code that this function will execute goes in between these two curly braces, just like in java and C.
The first statement that this funciton will execute is an if-else statement
The if condition tests wether or not the questionIndex variable that we just created exceeds the length of
the questions array that we just created (-1 because indexing starts with 0):
if (questionIndex <= (questions.length - 1))
If this if condition evaluates to true, then we will
execute the code in between the curly braces that imediatley follows:
This looks intimidating at first but it's very simple:
- The document keyword tells JS to go into the HTML document that were referring to here (in this case, the file that the script tags are contained in)
- Then, on this HTML document, we call the querySelector function and pass in the parameter '#question'
- What this does, is tell JS to look for the element in the document with the ID 'question'
- If you remember, we had 2 paragraph tags in the html file, one of which had an ID of 'question'
- Side note: if we used a . instead of a #, we would be looking for the element with the class of question.
- Then, we reference the 'innerHTML' property of the element. The innerHTML property refers to the text that goes in between the two paragraph tags with ID question
- We want to stick the question in this element of the HTML file, so we set this value equal to questions[questionIndex].q
- questions[questionIndex].q is accessing the array of objects that we just made.
- The questionIndex variable that we just made determines which of the 5 objects we will insert into the file.
- We use the . notation to access key values of objects, so we insert the 'q' key value of the object into the file
If the if condition evaluates to false, we will execute this block of code:
- That same paragraph element that we were referring to in the if statement just before, is now being populated with a string, rather than a key value of an object in an array.
- The string is "Game Over" which makes sense, because the if statment tested whether or not the question that the user was on was under the max. So, if this evaluates to false, thereby triggering the else statement, then that means that the user has completed all of the questions.
- It also populates that other paragraph tag's inner HTML with a concatenated string
- In JS, we use the + sign to concatenate strings
- We are sticking in a string that says "Final Score" followed by the value of the score variable, "out of" followed by the length of the questions array that we just made.
We also need to create a function that updates the score
We do this just like we did before when we were populating the paragraph tag.
We say:
Function Calls
In order to start the game, we must call these functions that we just created.
In order to call a function, just type in the name of the function followed by open and closed parentheses (enclosing whatever parameters you are providing, in this case there are none) followed by a semicolon.
This is pretty much the same in all scripting languages
The two functions that we just created will now be executed
Since the current value of questionIndex is 0, according to the code in the renderQuestion() function, the element with ID 'question' will be populated with the 'q' key value of the object in the questions array with index 0.
If this is confusing, read over the if statement inside of the renderQuestion function and think about the logic behind it again.
JavaScript events
In order to register the user's answers, we must use a JavaScript feature known as 'events'.
Ok, this is a lot to take in again, but once we break it down by each statement it is much more simple.
First, we type
'document.onkeyup' tells JavaScript: when the user presses a key, do this -
What is JavaScript gonna do? it is going to execute whatever function we wet this equal to.
In this case, we set it to an anonymous function with a parameter 'event'
This 'event' parameter is going to hold the value of whatever keyboard letter the user typed in
The first thing we say in the function is:
Which says, if the questionIndex variable value is == (equal to) the length of the question array, return.
Just like in java and other scripting languages, return will end the function and return the value that follows, in this case, nothing
Next, we create a variable to hold the value of the key that the user typed in, converted to lower case:
Next we execute an if else statement, only if the user pressed t or f. This is because the only possible answers are true, or false, so we only need to check if the user was right if they pressed one of these two keys
If the users answer is == to the "a" key value in the object at the questionIndex, then the user got it right. So we alert them with a string "correct" and we increment the score by 1 by saying score++;, then call the updateScore function so that the HTML page will display the updated score
If the user pressed t or f, but got it wrong: then we alert them with a string that says "wrong"After the user presses t or f, whether or not they got it right or wronxg we must increment the questionIndex variable so that they can move to the next question, then call the renderQuestion() function so that the page is populated with the new question.

here is a fairly quick and easy skirt pattern you could whip up in an afternoon for that special little girl in your life. It's a great way to use up some fabric, as you only need a small amount.
What you need:
The width of fabric use was 112cm or 44"
29" fabric x width of fabric if you want the same fabric for both skirt tiers or 11" for the top tier and 2 x 9" strips for the bottom tier
contrasting thread
elastic for waist band, you can use standard elastic suitable for waist bands or use buttonhole elastic, approximately 3/4" wide
1 button if using button hole elastic
Instructions:
Cut 1 11" strip by width of fabric and cut 2, 9" strip by width of fabric. Overlock (serger) or hem along each top and bottom edge of all the fabric strips to prevent fraying.
Take the 9" strip and along the bottom edge, fold it up by 1/4", and press. Fold up a further 1" and press. Sew along the pressed edge to make your skirt hem.
Fold the fabric in half, right sides facing and pin along edge. Sew with a 1/2" seam. Overlock or hem the seam.
Fold fabric so right side is facing out. Loosen the tension on your sewing machine and length the stitch and sew two gathering rows along the top of your skirt tier. Start the first gathering row 1/2" in from the top of the tier. Start the second gathering row about 1/4" from the first gathering row. Leave a tail at each end of the gathering rows, as this will help you tie the cotton when you are gathering it up and prevent you pulling out the stitches. Set aside.
Next take the 11" strip and fold in half so right sides of fabric are facing in. Pin and sew the side seam with a 1/2" seam allowance. Overlock the edge.
Pick up the 9" strip and tie one end of the gathering treads together so they don't pull through. Start gently pulling up the thread until it matches the bottom hem of the 11" skirt tier.

Go through the “Joining Table Data with SQL" section of https://teamtreehouse.com/library/querying-relational-databases
Work through the Codecademy SQL Tutorial Section 4 (Multiple Tables)
In SQLite on your own machine, you are going to create the tables for a microblogging platform (an app similar to Twitter). Your database should be able to store user information and posts by specific users. One post must belong to exactly one user. One user can have many posts. Later, we’ll add the ability for users to follow each other, but not now.
Here’s a sample schema:
- a table named: `users`
- which has a text field named: `name`
- and a text field named: `email`
- a table named: `posts`
- which has an integer field named: `user_id`
- and a text field named: `content`
Enter the SQLite command line program using the terminal commad sqlite3 twitter.sqlite3
. (This will save your database to a file called twitter.sqlite3
). Once there, use SQL statements to create two tables according to the spec for the two tables in step 1.
Once you have your two tables set up, compare your table set-up with another apprentice’s.
Add sample data to the tables yourself (make up some users and posts).
Try writing queries that get data such as:
Now let’s perform a database migration. We will add a new column to an existing table in our database. Add a text field named: bio
to your existing users
table!
Add some sample data to your new bio
fields, but not for every user (leave some of their bios blank).
If you complete the above, we’ll move on to creating a join table.
Add a new table named follows
that has an int field follower_id
and an int field followed_id
. Draw a picture for this table.
follows
, look for follower_id
2, and get all of the user IDs that are in those rows’ followed_id
fields. Then get the users by that set of user IDs.followed_id
)
follows
, look for followed_id
2, and get all of the user IDs that are in those rows’ follower_id
fields. Then get those users.


Nyzo version 473 (commit on GitHub) adds an override option for the new-verifier vote.
Determination of which verifiers to allow into the mesh is a two-step process. First, each verifier votes on which new verifier it calculates should be admitted next. Second, the tally of these votes is used in the computation of the chain score for blocks. This is the score that is used by verifiers to guide the voting process for freezing blocks.
This update was released in response to the joining of the mesh by a number of verifiers that, for reasons not yet determined, are not producing blocks and are not joining the cycle, despite other verifiers trying to allow them to join. Enough of these problematic verifiers had joined the mesh that they preventing other, properly configured, verifiers from joining the cycle.
While a later update will be issued to improve the automatic process, such an update will need to be carefully crafted and tested, as modifications to automatic processes such as this can be disastrous if released hastily and without sufficient review.
This update takes advantage of the two-step process and the ability of a small number of verifiers to influence the process to break the gridlock that the system was experiencing. In an ideal situation where all verifiers are in perfect agreement, every verifier in the current cycle will have voted for the same new verifier to admit to the cycle. The scoring process is designed to allow either this preferred verifier or the second- or third-place verifiers in the voting process to join, with preference given to the verifiers that received more votes.
Because of the natural consensus that will give most or all of the automatic votes to a single verifier, casting just a few votes for a different verifier is enough to get that other verifier into the top 3 in total votes received. This update allows a message to be sent to a verifier, signed by that verifier's private key, to manually override the vote that was automatically calculated.
The first step in creation of a new message in Nyzo is the assignment of the message numbers in the MessageType enumeration. The numerical value is always included in the enumeration name to make consistency of ordering easier to maintain and verify where the enumeration is used.
The second step is creation of the the message objects. In this case we need an object for both the request, to carry the identifier of the verifier for which we want to vote, and the response, which carries a flag indicating whether the request was approved and a message to explain the approval state.
The request class is NewVerifierVoteOverrideRequest.
The response class is NewVerifierVoteOverrideResponse. The constructor of this class processes the request and sets or removes the override as necessary.
The MeshListener class creates and sends a response to the request.
The Message class deserializes message objects from messages. The getByteArray() method was added to make message object deserialization methods easier to read by condensing reads of byte arrays from two lines to one.
The NewVerifierVoteManager class stores and serves the override.
Finally, the NewVerifierQueueManager class uses the override and erases it when the verifier joins the cycle. The comment explains a potential thread race that is not significant enough in potential frequency or in adverse impacts to warrant the additional code complexity or effort necessary for mitigation.

Age is just a Number; Heavy Driver in Kerala Tourist Bus : Video Viral
by AanavandiFor many of us, driving is a key aspect of maintaining our independence as we age. By reducing risk factors and incorporating safe driving practices, you may be able to continue driving safely long into your senior years.
Everyone ages differently, so there is no arbitrary cutoff as to when someone should stop driving.
However, older adults are more likely to receive traffic citations and get into accidents than younger drivers.
What causes this increase? As we age, factors such as decreased vision, impaired hearing, slowed motor reflexes, and worsening health conditions can become a problem.
Age is just a Number; Heavy Driver in Kerala Tourist Bus : Video Viral
Aging does not automatically equal total loss of driving ability. There are many things you can do to continue driving safely, including modifying your car, altering the way you drive, and addressing any physical issues that can interfere with driving.
Regular check-ups are critical to keep you in the best possible driving shape.
Get your eyes checked every year. Make sure that corrective lenses are current. Keep the windshield, mirrors, and headlights clean, and turn the brightness up on the instrument panel on your dashboard.
Have your hearing checked annually. If you need hearing aids, make sure you wear them while driving. Be careful when opening car windows, though, as drafts can sometimes impair a hearing aid’s effectiveness.
Talk with a doctor about how ailments or medications can affect your driving ability. For example, if you have glaucoma, tinted eyeglasses can help to reduce glare.
Get plenty of sleep. Getting enough sleep is essential to driving well. Ensure that you’re sleeping well and talk with your doctor about the effect sleep medications may have on your driving.

Chapter 4: Water |
General Facts About WaterAstronomers often refer to the Earth as the "Blue Planet," so abundant is the water that covers 70% of the planet's surface. Ninety-seven percent of the earth's water is in the oceans, but that water is not readily available for human use because of its high salt content. Of the 3% that consists of fresh water, two thirds is locked in glacial and polar ice. That leaves only 1% of the earth's water available for human use.
Scientists believe that life began in the oceans. If that is true, then we apparently took part of the oceans with us when we left our watery birthplace, for fully 70% of the human body is made up of water. A newborn's body consists of 77% water while an adult's consists of approximately 70%. The percentage gradually decreases throughout life with the elderly's body consisting of only 50% water. |
|||||||||||||||||||||||||||
|
Want to stay young? Drink plenty of pure water! Every cell in the human body contains water, which is
necessary for virtually every chemical reaction required to keep us alive
and healthy. We can live for weeks without food but only a few
days without water. Water is needed to carry oxygen and nutrients to the
cells, to dissolve minerals, for lubricating the joints, moistening and
protecting body tissues and organs, and for flushing out waste products.
When we don't get enough water a condition known as dehydration
occurs. The symptoms of dehydration include thirst, less frequent urination,
dark colored urine, dry skin, fatigue and lightheadedness. The symptoms
of dehydration in children include dry mouth and tongue, no tears when
crying, no wet diapers for 3 hours or more, sunken abdomen, eyes or cheeks,
high fever, listlessness, irritability and skin that does not flatten
when pinched and released. Today, with growing populations and increasing pollution of our natural resources, we are facing a water crisis. The World Health Organization estimates that over one billion people lack safe drinking water, and water borne diseases are responsible for the deaths of 4,000 children every day! It is estimated that the average American uses about 50 gallons (190 l) of water per day. This includes not only water for food preparation and drinking, but all other uses as well, including showering, flushing the toilet, etc. During an emergency, when our municipal water is cut off, we are obviously going to have to make do with much less! The medical profession tells us that we should drink 8 glasses of water a day. The US National Research Council recommends a total of 2.7 liters (about 3 quarts) of water (including food sources) for women and 3.7 liters (about a gallon) for men. The actual amount of water we need will vary depending on temperature, humidity and activity level. In hot climates and when the level of activity is high, the human body may require up to two gallons (8 l) of water per day to avoid dehydration. Survivalists usually agree that when computing your water needs during an emergency you should plan on one gallon (4 l) of water per person per day. This allows for drinking, food preparation and minimal washing (such as sponging off.) During hot weather and especially when the activity level is high this amount should be doubled.
A water dispenser like the one pictured above, along with a few extra bottles of purified water, will provide emergency water for drinking and food preparation during a short-term emergency. We keep this unit in our kitchen for our everyday drinking water needs, refilling it with a Nature's Spring Countertop Reverse-Osmosis Water Filter. When your municipal water fails, one of the easiest places to get a small amount of emergency water is from the water still remaining in the pipes in your house. First shut off the main water valve into your house to prevent the water from flowing back into the water main. Then open a tap at the highest location in your house, to allow air to flow into the pipes, and collect water from a tap at the lowest location in your house. You may also be able to use the water stored in your water heater by collecting it from the drain tap located near the bottom of the unit. |
|||||||||||||||||||||||||||
Preparing for a DisasterSince water is so vitally important, and because so much of it is needed for survival, we should prepare for a disaster by storing as much as we practically can, and by making preparations for collecting additional water. Since the water we collect will most likely be contaminated, we will also need to be prepared to filter and purify our water. Polluted water is extremely dangerous. It has been estimated that worldwide, water borne diseases are responsible for about half of all hospitalizations. Bacteria in our drinking water is the cause of many deadly diseases, such as cholera, amebic dysentery and life-threatening diarrhea. Even in the best of times the water in our rivers, streams and lakes is unsafe for drinking. Imagine how much worse it will become when our sewage treatment systems are not working properly. There is no doubt that more human wastethe primary source of dangerous disease-causing bacteriawill enter our water supply after a disaster strikes. Even water collected from rain and snow, due to pollution in the air, must be treated before it is consumed. Survivalists tell us that rainwater should be treated pretty much the same as pond or river water. |
|||||||||||||||||||||||||||
|
Storing WaterEven the purist water will go bad due to bacterial growth when stored over an extended period of time. Whenever water is stored for an emergency it should be rotated and replaced regularly. The old water should be used (I use it to water my garden when rain is scarce) and the storage containers should be washed and rinsed and replaced with fresh water each year. The shelf-life of stored water can be extended by adding a small amount of household chlorine bleach (e.g., Clorox) or Calcium Hypochlorite solution (see below.) To prepare water for storage add 4 drops of chlorine bleach per gallon of water (1 drop per liter). For larger vessels add one teaspoon of chlorine bleach per 30 gallons (4 cc per 100 liters). Don't worry about being exact with your measurements. Avoid buying chlorine bleach with scents or other additives. Use only plain old-fashioned chlorine bleach or calcium hypochlorite (swimming pool "Shock".) Water can be stored in many different types of containers, from small plastic bottles to 55 gallon (200 l) drums. Old milk containers are not recommended because they can never be cleaned thoroughly enough to prevent spoilage from bacteria. Five gallon plastic containers are great. They will also come in handy if you need to transport water. Fifty-five gallon (200 l) plastic drums are ideal if you have room to store them. These can be quite expensive if purchased new, but there are always used drums available if you search for them. I have purchased used drums for as low as $10 each from retail outlets, and for as little as a few dollars each at estate sales. Be sure that your drums have not been used to store toxic materials. All plastics are slightly porous and it is impossible to completely remove the toxins from the plastic. Beverage bottling companies usually receive their ingredients in food-grade plastic drums that are perfectly suitable for water storage. If you are unsure about what was originally stored in your plastic drum, then use that drum for non-potable water only. Non-potable water will come in very handy for washing and for flushing your toilet. I suggest that you use a large permanent marker to mark your water storage containers as either "Potable" or "Non-Potable." |

Purifying WaterWe will now consider the various ways that water can
be filtered and purified. As we will see, some methods do not lend
themselves well to emergencies. The method you will use will depend on
the equipment you have available and how dirty your water is. There are three basic ways to purify water:
Mechanical Filtration
|
|||||||||||||||||||||||||||
|
Conserving WaterAs we saw earlier, due to overpopulation and pollution, clean fresh water is a diminishing resource worldwide. The U.S. Environmental Protection Agency (EPA) states that runoff from driveways, streets and yards is the single biggest threat to the health of American waterways. According to the EPA, Americans apply 67 million pounds of pesticides to their lawns every year. Agricultural run-off of fertilizers and pesticides has created a dead zone in the Gulf of Mexico where the Mississippi River enters and for miles out into the Gulf. Even during normal times water should be conserved as much as possible, and efforts should be made to minimize the pollution of our streams, lakes and oceans. In the future, hopefully more organic methods will be employed for growing crops and the use of chemicals can be reduced. Homeowners can reduce pollution of our fresh water by refraining from using chemical fertilizers and weed killers on their lawns. Ironically, two of the weeds that people find most troublesomedandelions and plantainsare also edible plants that can serve as excellent survival foods (more on these "weeds" later.) During times of emergency, when the municipal water
has ceased to flow, even more attention will need to be given to water
conservation. Toilet flushing, for example, will have to be kept to a
minimum. Excessively long and frequent showers will have to be eliminated.
We will also have to learn how to reuse water as much as possible. If our sewer systems are backed up, care must be taken
to insure the proper disposal of human and animal wastes. We must endeavor
not to pollute our streams and lakes, which will no doubt be serving as
someone'sperhaps our ownsource of fresh water. Human
waste is a very dangerous contaminant of water resulting in many deadly
waterborne diseases including life-threatening diarrhea. We will discuss
proper waste disposal, including disposal of human waste, in a later chapter
of this web site.

Action Step 8: Planning For Your Water NeedsA. How Much Water? Open your Action Planner to the page where, in Action Steps 1 and 2, you made a list of the potential emergencies that concern you along with the scope and duration that each emergency is likely to involve. Consider now the longest duration that you considered likely for the events that cause you the most concern. Is it one week? One month? Six months? Now consider the number of people in your family and figure on needing at least one gallon (4 l) of water per person per day. Do you have other family members who might move in during an emergency or a neighbor who you might want to help? (Your neighbors will probably not be as prepared, and you must decide if you will be willing and able to help them.) Multiply the number of people by the number of days. That is the minimum number of gallons of water that you will need to get through the longest siege that you foresee. Write that number down in your Action Planner along with the words "water needed." If that sounds like a lot, remember that you should be able to replenish some of your water supply by collecting precipitation (rain or snow) or by scrounging from a lake or stream. But to do that you must have the necessary supplies, including purification and filtration equipment. If you will be able to collect additional water to help replenish your stored water, you might be wondering how much water you will actually need to store. I recommend that you store at least a 30 day supply. So multiply the number of people by 30 and that will give you the minimum number of gallons that you will need to put into storage. Write that number in your Action Planner along with the words "minimum storage." Remember that one gallon per person per day is the absolute minimum, not allowing for washing. Additional water could turn out to be greatly appreciated by everyone! If practical you should store two gallons per person per day. B. Water Checklists: In Action Step 6 you created a "Get" list and a "Do" list for water. Turn to that page now. In the "Get" column begin making a list of the items that you would like to acquire to meet your water needs, including collection materials, water treatment chemicals, water filters, etc. Continue on the back side of the page if necessary. In the right column under "Do" begin making a list of the things that you would like to do, or accomplish, to help you meet your goal for water storage. This list might include things like: Locate water sources around my home, Ask neighbors about local wells, Build a system to collect rainwater, etc. When you acquire an item or accomplish a task check it off your list. As you think of additional items add them to your lists. You do not have to run out and buy everything that you need right now. But start somewhere, even if it is only with one five gallon storage container. You can add to your stock as you are able, until you have reached your goal. Even though you do not have everything that you need right now, you will have made a start, and you will have a plan. It will only be a matter of time before you will reach your goals. Below is a sample "GET" list of items that you may want to acquire and a sample "DO" list of things that you might want to accomplish to help you prepare for your water needs during an emergency. Use these lists to help you formulate your own check lists:

Hamilton responds to calls for knighthood
Cape Town - Mercedes' Lewis Hamilton says it is an honour to hear English fans call for his knighthood, but insists he does not expect to receive the honour.
Hamilton, who has already received an MBE from the Queen, is without a doubt Britain's most successful Formula 1 driver.
Earlier this month he wrapped up his sixth Drivers' Championship, putting him just one away from equalling Michael Schumacher's all-time record.
His success has led to calls from the likes of Motorsport UK chairman David Richards for the 34-year-old to be knighted.
Hamilton has downplayed the hoohah.
"I don't really like to think too much about it," he said.
"Just the fact that people have mentioned it, it's already an honour, but it's not been something that I've been chasing in my life.
"If, at any point, that was to happen, I don't particularly know how I would handle it.
"I have stood in front of Her Majesty The Queen before and it was pretty incredible and I think she's just awesome.
"Again, I don't think it's going to happen, and again, it doesn't bother me if it doesn't.
"It doesn't mean I'm not British.
"It doesn't mean I'm not continuing to try and raise the flag as well as I can but I do appreciate all the support I've had from my fans and also from the British media."
Pressed as to why he didn't think it would ever happen, he replied: "I don't know, I just don't think about it. I don't know."
Although Hamilton is arguably one of the UK's most successful sportspeople, his team boss Toto Wolff feels he doesn't receive the appreciation that his success deserves.
"It is difficult for me, as an Austrian, to understand the importance of the British honours system," Wolff told The Telegraph.
"What I feel is that there is a lot of polarisation around Lewis, particularly in the UK. Why that is, I don't know.
"But one thing I'm certain of is that one day, if he decides to stop his career, people will acknowledge his successes and what a great superstar he was."

{{ page.description }}
This article is part of a series called Type-safe DI composition. In the previous article, you saw a C# example of a type-safe, nested DI Container. In case it's not clear from the article that introduces the series, there's really no point to any of this. My motivation for writing the article is that readers sometimes ask me about topics such as DI Containers versus type safety, or DI Containers in functional programming. The goal of these articles is to make it painfully clear why I find such ideas moot.
In the previous article, you saw how you can use container nesting to implement a type-safe container of arbitrary arity. You only need these generic containers:
public sealed class Container public sealed class Container<T1> public sealed class Container<T1, T2>
You can achieve arities higher than two by nesting containers. For example, you can register three services by nesting one container inside another: Container<T1, Container<T2, T3>>
. Higher arities require more nesting. See the previous article for an example with five services.
How did I get the idea of nesting the containers?
It started as I was examining the constructor of the CompositionRoot
class:
private readonly Container<IConfiguration, Container<Container<Container<IRestaurantDatabase, IPostOffice>, IClock>, IReservationsRepository>> container; public CompositionRoot(Container<IConfiguration, Container<Container<Container<IRestaurantDatabase, IPostOffice>, IClock>, IReservationsRepository>> container) { this.container = container; }
Those are, indeed, wide lines of code. No 80x24 box here. If you ignore all the container nesting, you can tell that the container contains five services:
IConfiguration
IRestaurantDatabase
IPostOffice
IClock
IReservationsRepository
CompositionRoot
:
IRestaurantDatabase
IClock
IReservationsRepository
IConfiguration
and IPostOffice
services are only present because they were required to create some of the other services. CompositionRoot
never directly uses these two services. In other words, there's a leaky abstraction somewhere.
It'd be more in spirit with the Dependency Inversion Principle (DIP) and the Interface Segregation Principle (ISP) if the constructor required only the services it needs.
On the other hand, it's easiest to create the container from its constituent elements if you can pass already-registered services along when registering other services:
var container = Container.Empty .Register(Configuration) .Register(CompositionRoot.CreateRestaurantDatabase) .Register(CompositionRoot.CreatePostOffice) .Register(CompositionRoot.CreateClock()) .Register((conf, cont) => CompositionRoot.CreateRepository(conf, cont.Item1.Item2)); var compositionRoot = new CompositionRoot(container); services.AddSingleton<IControllerActivator>(compositionRoot);
I realised that the container needed a way to remove services from the public API. And it hit me that it'd be easier if I separated the container from its registry of services. If I did that, I could define a single generic Container<T>
and even make it a functor. The payload could be a custom Parameter Object, but could also just be a tuple of services.
From Thinking with Types I knew that you can reduce all algebraic data types to canonical representations of Eithers and tuples.
A triple, for example, can be modelled as a Tuple<T1, Tuple<T2, T3>>
or Tuple<Tuple<T1, T2>, T3>
, a quadruple as e.g. Tuple<Tuple<T1, T2>, Tuple<T3, T4>>
, etcetera.
Connecting those dots, I also realised that as an intermediary step I could nest the containers. It's really unnecessary, though, so let's proceed to simplify the code.
Instead of a Container<T1, T2>
in addition to a Container<T1>
, you only need the single-arity container:
public sealed class Container<T> { public Container(T item) { Item = item; } public T Item { get; } // More members to follow...
Apart from overriding Equals
and GetHashCode
, the only member is Select
:
public Container<TResult> Select<TResult>(Func<T, TResult> selector) { if (selector is null) throw new ArgumentNullException(nameof(selector)); return new Container<TResult>(selector(Item)); }
This is a straightforward Select
implementation, making Container<T>
a functor.
You can use the Select
method to incrementally build the desired container:
var container = Container.Empty.Register(Configuration) .Select(conf => (conf, rdb: CompositionRoot.CreateRestaurantDatabase(conf))) .Select(t => (t.conf, t.rdb, po: CompositionRoot.CreatePostOffice(t.conf, t.rdb))) .Select(t => (t.conf, t.rdb, t.po, clock: CompositionRoot.CreateClock())) .Select(t => (t.conf, t.rdb, t.po, t.clock, repo: CompositionRoot.CreateRepository(t.conf, t.po))); var compositionRoot = new CompositionRoot(container); services.AddSingleton<IControllerActivator>(compositionRoot);
The syntax is awkward, since you need to pass a tuple along to the next step, in which you need to access each of the tuple's elements, only to create a bigger tuple, and so on.
While it does get the job done, we can do better.
Instead of using method-call syntax to chain all these service registrations together, you can take advantage of C#'s query syntax which lights up for any functor:
var container = from conf in Container.Empty.Register(Configuration) let rdb = CompositionRoot.CreateRestaurantDatabase(conf) let po = CompositionRoot.CreatePostOffice(conf, rdb) let clock = CompositionRoot.CreateClock() let repo = CompositionRoot.CreateRepository(conf, po) select (conf, rdb, po, clock, repo); var compositionRoot = new CompositionRoot(container); services.AddSingleton<IControllerActivator>(compositionRoot);
In both cases, the container
object has the type Container<(IConfiguration conf, IRestaurantDatabase rdb, IPostOffice po, IClock clock, IReservationsRepository repo)>
, which is still quite the mouthful. Now, however, we can do something about it.
The CompositionRoot
class only needs three services, so its constructor should ask for those, and no more:
private readonly Container<(IRestaurantDatabase rdb, IClock clock, IReservationsRepository repo)> container; public CompositionRoot( Container<(IRestaurantDatabase rdb, IClock clock, IReservationsRepository repo)> container) { this.container = container; }
With that injected container
it can implement Create
like this:
public object Create(ControllerContext context) { if (context is null) throw new ArgumentNullException(nameof(context)); var t = context.ActionDescriptor.ControllerTypeInfo; if (t == typeof(CalendarController)) return new CalendarController( container.Item.rdb, container.Item.repo); else if (t == typeof(HomeController)) return new HomeController(container.Item.rdb); else if (t == typeof(ReservationsController)) return new ReservationsController( container.Item.clock, container.Item.rdb, container.Item.repo); else if (t == typeof(RestaurantsController)) return new RestaurantsController(container.Item.rdb); else if (t == typeof(ScheduleController)) return new ScheduleController( container.Item.rdb, container.Item.repo, AccessControlList.FromUser(context.HttpContext.User)); else throw new ArgumentException( $"Unexpected controller type: {t}.", nameof(context)); }
That's more readable, although the intermediary Item
object doesn't seem to do much work...
You can create a container
with the desired type like this:
Container<(IRestaurantDatabase rdb, IClock clock, IReservationsRepository repo)> container = from conf in Container.Empty.Register(Configuration) let rdb = CompositionRoot.CreateRestaurantDatabase(conf) let po = CompositionRoot.CreatePostOffice(conf, rdb) let clock = CompositionRoot.CreateClock() let repo = CompositionRoot.CreateRepository(conf, po) select (rdb, clock, repo); var compositionRoot = new CompositionRoot(container); services.AddSingleton<IControllerActivator>(compositionRoot);
Notice that the only difference compared to earlier is that the select
expression only involves the three required services: rdb
, clock
, and repo
.
This seems cleaner than before, but perhaps you're left with a nagging doubt: Why is the Container<T>
class even required? What value does its Item
property provide?
And perhaps another question is also in order: Does the Select
method shown even define a lawful functor?
Read on.
