1 Listen to this! Some day there will be a righteous king,
and his officials will help him to rule justly.
2 Each of them will be like a shelter from the wind
and a refuge from the storm.
They will be like streams of water in the desert,
like the shade under a huge rock in a very hot and dry land.
3 When that happens, those leaders will enable people who have not understood God's truth to understand it,
and they will enable those who have not paid attention to God's truth to pay attention to it.
4 Even those who act very hastily will have good sense,
and those who cannot speak well will speak fluently and clearly.
5 At that time, people who are foolish will no longer be admired,
and scoundrels will no longer be respected.
6 Foolish people say things that are foolish,
and they plan to do evil things.
Their behavior is disgraceful,
and they say things about Yahweh that are false.
They do not give food to those who are hungry,
and they do not give water to those who are thirsty.
7 Scoundrels do things that are evil and that deceive people;
they plan to do evil things;
by telling lies in court they cause poor people to have trouble,
even when what the poor people are requesting is fair.
8 But honorable people plan to do honorable things,
and they do those honorable things, so they succeed.
9 You women of Jerusalem who think that you are very secure
and think that everything is going well,
listen to what I say!
10 After one year is ended, you who now are not worried about anything will tremble,
because there will be no grapes for you to harvest
and no other crops to harvest.
11 So tremble now, you women who are not worried about anything!

Your houses where you had joyful parties and your city where you have been happy will be gone.
14 The king's palace will be empty;
there will be no people in the city that now is very noisy.
Wild donkeys will walk around and flocks of sheep will eat grass
in the empty forts and watchtowers.
15 It will be like that until God pours his Spirit out on us from heaven.
When that happens, the deserts will become fertile fields,
and abundant crops will grow in those fertile fields.
16 People will act justly in those desert areas,
and people will act righteously in those fertile fields.
17 The result of their acting righteously will be that there will be peace,
the land will be tranquil, and people will be secure forever.
18 My people will live in their homes peacefully, and safely, and calmly,
in places of rest.
19 Even if a severe hailstorm knocks down the trees in the forest,
and all the buildings in the city are blown down,
20 Yahweh will greatly bless you;
you will plant seeds in fields alongside the streams
and there will be abundant crops.
Your donkeys and cattle will easily find grass to eat when you send them out into pasture.


This API returns (and in some places accepts) JSON. Unless otherwise specified, the JSON data structure returned will be a JSON object with a status key describing how the API behaved with respect to the request. Any response data will be in the data key. Any messages will appear in the message key. API endpoints below will describe any other information they return, and will specify if they differ from this convention. CORS / JSONP should work fine too.
Sign up for a Cottage Labs account at accounts.cottagelabs.com. Once signed up, view your account details page to see your user ID and your API key.
COMING SOON: have multiple API keys and generate new ones as required.
Once you have these credentials, they can be used to authenticate against any API route. Provide them either as headers in your request, using header names x-id and x-apikey or include them as URL query string parameters named id and apikey. For convenience, the URL query parameters can also accept email or username instead of id.
Note that whilst this gives you the ability to authenticate, API endpoints will also enfore authorisation restrictions using roles and groups.
After authentication, authorisation to perform certain actions is controlled by membership of roles and groups. The Cottage Labs accounts API (detailed below) provides routes for controlling membership of roles and groups. External services that use the Cottage Labs accounts API can customise the roles and groups that are used, but the conventional usage is as follows:
There is a default set of cascading roles - e.g. root is most senior, and is senior to all those following it. If any of these roles are used, then authorisation checks will take cascading seniority into account. Therefore, any user account with the owner role will be authorised whenever the owner role is checked for, but ALSO whenever the auth role is checked for, or any other role that comes after it.
GET a list of all user account IDs.
GET a count of all user accounts.
GET a list of user IDs and count of all user accounts that appear to be online.
GET just the count of how many user accounts appear to be online.
GET the user account identified by the :id parameter (can be user ID, email address, or username). To the user of the queried account it returns the profile, roles, username, and emails. To system accounts it also returns the related system data.
GET the current status of the account - is it online, is it idle.
POST to this endpoint provides a way for external systems to indicate that the user is online and not idle. Keeps the online status of the user up to date when they are using external systems.
POST updates to the profile of the user. Partially updates the user profile with the data provided, but leaves other profile data intact. Accessible to the user of the account itself, or anyone delegated control over that account.
PUT works as above but replaces the entire user profile with the provided data, overwriting anything that was previously in the profile.
POST and PUT similiarly to the above profile endpoint, but updates the relevant system section of the user account, and is authorised for the user that has relevant permissions for said system - NOT authorised for the user account owner.
GET with a comma-separated list of grouproles, and returns whether or not the user has the necessary authority. Return data will indicate false if not, or else the name of the first grouprole that the user has permission on.

SPORTS |
Olympic sports are contested in the Summer Olympic Games and Winter Olympic Games. The 2016 Summer Olympics included 28 sports, with five additional sports due to be added to the 2020 Summer Olympics program; the 2014 Winter Olympics included seven sports. The number and types of events may change slightly from one Olympiad to another. Each Olympic sport is represented by an international governing body, namely an International Federation (IF). The International Olympic Committee (IOC) establishes a hierarchy of sports, disciplines, and events. According to this hierarchy, each Olympic sport can be subdivided into multiple disciplines, which are often mistaken as distinct sports.
Swimming has been a sport at every modern Summer Olympics. It has been open to women since 1912. Along with track & field athletics and gymnastics, it is one of the most popular spectator sports at the Games. Swimming has the second largest number of events (after Athletics).
Basketball at the Summer Olympics has been a sport for men consistently since 1936. Prior to its inclusion as a medal sport, basketball was held as a demonstration event in 1904. Women's basketball made its debut in the Summer Olympics in 1976. The United States is by far the most successful country in Olympic basketball, with United States men's teams having won 15 of 18 tournaments in which they participated, including seven consecutive titles from 1936 through 1968.
Archery had its debut at the 1900 Summer Olympics and has been contested in 16 Olympiads. Eighty-four nations have competed in the Olympic archery events, with France appearing the most often at 31 times. The most noticeable trend has been the excellence of South Korean archers, who have won 23 out of 34 gold medals in events since 1984. .

This is the second post in a set of blog posts about mental poker. The previous post can be found here: Mental Poker - An overview of approaches.
Following on from the previous discussion about the general approaches to mental poker, this post takes a deeper look on what is actually required to randomly generate a card in a distributed way. Firstly, standard ElGamal encryption is discussed before investigating how it can be modified to work in a distributed setting.
Warning - Here be dragons. If you are not interested in an overly verbose look into how each step could work then save yourself and get out now. If you're interesting in learning more about the maths behind random card generation then read on!
As discussed in the previous post, the multiplicatively homomorphic property of the ElGamal encrpytion scheme is the key ingredient that enables individuals encypted card choices to be combined to form a global card choice. The standard version of ElGamal encryption is an asymmetric key encryption algorithm, hence a public and private key pair must be generated in order to encrypt and decrypt messages. In order for Bob to send Alice an encrypted message the three components must be combined:
ElGamal encryption is defined over a cyclic group \(G\) of order \(q\), where \(q\) is usually a large prime. In order for Alice to receive messages that only she can decrypt she must first generate the key pair as follows:
The public key consists of the quadruple \((G,q,g,h)\) which is then published and becomes known to Bob. The private key \(x\) is (obviously) kept secret.
Given Bob has learned Alice's public key, he can now send her a message \(M\) via the following steps:
The ciphertext that Bob sends to Alice is the pair \((c_1,c_2)\). Note that if someone knows the mapped plaintext value \(m\) and the cipher text \((c_1,c_2)\) then they can easily work out the ephemeral key \(s\) by computing \(s = c_2m^{-1}\). Hence, as the name suggests, ephemeral key \(s\) (and \(k\) value) should be computed every time a message is sent.
Given Alice has recieved Bob's ciphertext \((c_1,c_2)\), she can decrypt it using her private key \(x\) as follows:
As noted above, during the encryption phase any plaintext message \(M\) must be first mapped to some value \(m \in G\) in a reversible way. As \(g\) is a generator for \(G\), we know that \(g^i \in G\). Furthermore, for the application of mental poker, we know that the the plaintext messages \(M\) will always represent card choices, and hence the message space is reduced to integers in the set \(\{1,...,52\}\). Thereforewe the reverse mapping function can be acquired by simply computing the two way map from all card choices \(\{i\}_{i=1}^{52}\) to their mapped messages \(\{g^i\}_{i=1}^{52}\) and performing lookups of each \(m\) or \(M\) value when necessary.
The standard ElGamal encryption scheme above assumes communication between two parties. However in the mental poker setting we have a variable number of players, usually between 2 and 8, and hence the scheme needs to be adjusted to enable joint encryption and decryption.
This can be achieved by creating a sharded private key which is distributed amongst all players using Pedersen’s protocol. Given \(n\) parties, Pedersen's protocol generates a distributed ElGamal key pair with private key \(x\) defined as: \[x = \sum_{j=1}^n x_j \mod q\] Each player \(P_j\) learns a unique share \(x_j\) of the distributed private key, meaning that no single players or subset of players can know the entirety of \(x\). The public key \(h\), by definition, becomes known to all players. Hence this adjustment allows all players to collectively encrypt a message \(M\) in such a way that the result can only be decrypted by all players jointly.
From Pedersen’s paper, the first step towards generating the ElGamal key pair is choosing a prime pair \((p,q)\) such that \(q\) divides \(p-1\). The simplest way to do this is to find a safe prime \(p\) of the form \(p=2q+1\) by repeatedly selecting a random, sufficiently large prime \(q\) until \(p=2q+1\) is also prime.
The next step is to choose a generator function \(g\) of a cyclic subgroup \(G\) of \(\mathbb{Z}^*_p\) such that \(G\) has order \(q\). Algorithm 4.80 from the Handbook of Applied Cryptography provides a way for us to compute a generator of \(\mathbb{Z}^*_p\):
Input: A cyclic group \(G\) of order \(n\), where \(n\) has prime factorization \(n = p_1^{e_1} p_2^{e_2}... p_k^{e_k}\)
Output: A generator \(\alpha\) of \(G\)
- Choose a random element \(\alpha \in G\)
- For \(i = 1,...,k\):
- Compute \(b ← \alpha^{n/{p_i}}\)
- If \(b = 1\) then go to step 1
- Return \(\alpha\)
As we have \(G=\mathbb{Z}^*_p\) with order \(p-1\) we know that the prime factorisation is \(2q\). Therefore there can be at most two iterations within step 2 and hence we only have to check that the two conditions hold: \[\alpha^{\frac{p-1}{2}} = \alpha^q \ne 1\] \[\alpha^{\frac{p-1}{q}} = \alpha^2 \ne 1\]
One final step remains: transform the generator \(\alpha\) of \(\mathbb{Z}^*_p\) into our desired generator \(g\) of \(G\). This can be achieved using the relation: \[g = \alpha^{\frac{p-1}{q}} \mod p\] \[ = \alpha^2 \mod p\] The above means that we now have the required \((p,q,g)\) for Pedersen's protocol. For brevity, the exact method by which these variables are decided upon between players is mainly skipped over here. A simple but not so rhobust approach is to have a random player perform the calculations and propose these, with the the players being able to validate the size and correctness of the chosen values.
Note: Seeing why this relation holds requires a quick crash course in groups and generators. \(\mathbb{Z}_n\) represents the group of integers modulo \(n\), i.e. \(\mathbb{Z}_n = \{0,1,...,n\}\). An integer \(x \in \mathbb{Z}_n\) is called a unit (and has an inverse) if the greatest common divisor of \(x\) and \(n\) is \(1\), i.e. \(\gcd(x,n)=1\). \(\mathbb{Z}_n^*\) represents the set of all units of the group \(\mathbb{Z}_n\).
This group is closed under modular multiplication. That is, for units \(x_1\) and \(x_2\), the element \(x_1 x_2 \mod n\) is also a unit and therefore in the group \(\mathbb{Z}_n^*\). Clearly, for some prime \(p\), we know that \(\mathbb{Z}_p^*\) has order \(p-1\) as \(\gcd(x,p) = 1 \, \forall \, x \in \{1,...,p-1\}\).
Given we have an efficient generator \(\alpha\) of \(\mathbb{Z}_p^*\) we know that \(\{\alpha^i\}_{i=0}^{p-1}\) describes the group \(\mathbb{Z}_p^*\). It follows that the generator \(g = \alpha^{\frac{p-1}{q}} \mod p\) describes a subgroup of \(\mathbb{Z}_p^*\) with order \(q\). The final deduction can be done using the fact that \(\mathbb{Z}_p^*\) is a cyclic group and that a subgroup of a cyclic group is itself a cyclic group. Therefore we know that \(g\) is an efficient generator of the cyclic group \(G\) with order \(q\).
As the card choice is generated via combining each players individual card choices there is good reason to ensure that players cannot change their choice after seeing others. In reality this is unlikely as each choice is encrypted so an attacker should not be able to deduce any information to help them change their initial choice, however a second layer of protection can still be added in via cryptographic commitments. These essential lock each player into their original choice in a verifiable way, preventing any retrospective changes. It also ensures that each player has actually submitted a card choice before anyone reveals their value.
A commitment scheme is a two party protocol that allows a committer Alice to send an unintelligible representation of a message \(m\), denoted by \(C(m,r)\), to a receiver Bob and a later date reveal the message \(m\) (by ‘opening’ her commitment).
Two key properties of a commitment scheme are unconditional hiding and computational binding. That is, the following two properties should hold:
A commitment is said to be non-malleable if, for a given commitment \(C(m,r)\) to message \(m\), it is impossible to efficiently generate a related commitment \(C(m',r')\) for message \(m'\). This property prevents any man-in-the-middle (MIM) attacks in which a malicious user can intercept and replace Alice’s messages to Bob without Bob discovering. Note that the risk of MIM attacks can be somewhat offset using other mechanisms such as end-to-end encryption of messages between parties.
One commitment scheme that shares many similarities with the ElGamal encryption scheme above is Pedersen commitments. The steps for Alice to make a Pedersen commitment to value m and send to Bob are as follows:
Bob chooses the public parameters:
Alice makes a commitment to a value \(m\):
At a later date, when Alice wants to open her commitment, she can send the values \((m,r)\) to Bob. Bob can then compute \(c' = C(m,r)\) using these values and verify that \(c'\) matches Alice's original commitment \(c\). If Alice attempts to change her message from the original value \(m\) then \(c' \ne c\) and Bob will know she is lying and terminate the session.
The above can now all be put together to form the protocol to generate the public and distributed private ElGamal encryption keys:
The private key is formed from the combination of all private key parts: \(x = \sum x_i \mod q\) which can only be known by someone who knows all private key parts. Therefore a ciphertext can only be decrypted if all participants work together. Furthermore, as long as there exists a player \(P_i\) that chooses their private key part \(x_i\) at random then the distribution of the private key \(x\) is computationally indistinguishable from the uniform distribution.
Note that the mental poker application somewhat simplifies the requirements of the key pair as, due to collusion, we do not require nor desire the private key to be recoverable by a subset of players. That is, no threshold scheme is required.
Within the distributed key setting, encryption works similarly to normal ElGamal. The main difference is that, due to the homomorphism of the encryption scheme, a shared, unknown encrypted message by combining each players individual encrypted messages.
In the mental poker scenario, we have each player \(P_i\) randomly choosing their card choice \(c_i\). Using the mapping function defined above, the partial encryption of each card choice is defined as \(E(c_i) = (g^{r_i}, g^{c_i}h^{r_i})\), where \(r_i\) is \(P_i\)'s private ephemeral key and \(h\) is the shared public key.
The jointly encrypted final card choice \(c\) is defined as: \[E(c) = E(\sum c_i) = \prod E(C_i) = (\prod g^{r_i}, \prod g^{c_i}h^{r_i})\] As all arithmetic is done modulo \(p\) the final card choice \(c\) will a random card choice, unknown to all players.
Once \(E(c)\) has been computed, it can only be jointly decrypted by all the holders of the private key parts. For a given ciphertext \(E(c) = (\alpha, \beta)\) as above, the complete decryption of plaintext message \(m\) is defined as: \[m = D(\alpha, \beta) = \frac{\beta}{\alpha^x} = \frac{\beta}{\alpha^{\sum x_i}} = \frac{\beta}{\prod \alpha^{x_i}}\] Therefore, each player can partially decrypt the message using their private key part \(x_i\) by computing the value \(\alpha^{x_i}\). Due to the discrete logarithm problem, this value is assumed to not reveal any information about each players private key part \(x_i\). The final plaintext card choice \(c\) can be obtained by combining these partial decryptions, computing the message \(m\) and then using the previously computed set \(\{g^i\}_{i=1}^{52}\) to reverse map \(m\) to \(c\).
This allows the final card choice \(c\) to be either dealt face up the table, via having everyone broadcasting their partial decryptions, or to a single player \(P_j\) face down, via having all other players share their partial decryption with \(P_j\).
Given this tidal wave of information, it should now be possible to deal a single card in a game of mental poker. Obviously there is far more to do but thankfully a lot of the heavy lifting is done. The next challenge is determining whether a subsequently generated card \(c'\) matches any cards already in play. Despite sounding simple, this task becomes quite involved as the only values available are the list of encrypted cards in play and \(E(c')\). The next blog post will aim to tackle this and move closer towards a complete mental poker protocol.

Why car seats and bulky coats are an unsafe mix for children
by WTMJ StaffCoats are essential during winter months and car seats are necessary for children when riding in the car. However, they don't mix, according to Children's Wisconsin.
Bulky winter coats affect how secure car seats are in protecting children. In a crash, the extra puffy coat material will compress, causing the harness to become loose and ineffective.
Experts say parents should dress their kids in thin, warm layers such as fleece or Thinsulate, a brand of synthetic fiber thermal insulation used in clothing.
Once the child is secured in the car seat, place a warm blanket over them or put their coat on backward over their arms and shoulders.
When securing the car seat, it should clip at armpit level while fitting snugly without any twists.
“I understand the thought of having to go through this each time you get in and out of the car is daunting, especially as you’re trying to keep yourself warm as well. But it really is important, even if you’re just going for a quick jaunt around the neighborhood,” wrote Lisa Klindt Simpson with Safe Kids Southeast Wisconsin. “Studies have shown that most crashes occur within 20 minutes or less from home and at relatively slow speeds.”
Motor vehicle crashes, wherever they occur, are the leading cause of death in children older than 1, according to Simpson.
This story was originally published by Jodie Filenius at WTMJ.

Just as harsh and negative as this may sound, it is indeed true. Like one of those hard to swallow pills. You know it is true, you just keep denying its plausibility. We live in a world of shattered dreams and broken lives where the only source of consolation we can justify for ourselves is through saying thick quotes on failures, hardships, and life. But once in a while, we stumble upon a quote like this which forces us to contemplate our entire lives- with a floodlight on our failures.
Wilde died at the early age of 46 but succeeded in leaving a lifetime of works and thoughts for the masses to deliberate and cogitate on. This quote simply stands as an underrated instance of the wit, flamboyance, and underlined satire that flowed in him. As acclaimed for his acuity Wilde understood what this world truly is, behind the veils of what it pretends to be.
A mistake doesn't necessarily make an experience. A mistake is a mistake. We ought to stop just chalking it up and begin dwelling on its negative impact as well. We can only learn from a mistake after we admit the fact that we've made it. Sadly, in most cases, we mask it up under the pretext of "experience earned the hard way" and move on without deriving either meaning or message from it.
Satire or not, some mistakes are irrevocable, damaging, and can cause reverberations that upset the entire course of our lives. Mistakes happen. But mostly we fail to feel the impact of them, to use an analogy from our nervous system. There are times when we might have been aware of the mistake and simply chose to ignore it. Often these prove fatal for our existence.
Experience, on the other hand, is a question of instinct about life. Experience is something we learn from- hopefully, reduce future risk or enhance future gain -rather than merely 'experiencing it (going through it)'. When Will Rogers said," Some people learn by reading. Some people learn by watching. Sadly, some folks just won't learn until they've peed on an electric fence." he was underlining the necessity of knowing what needs to be experienced and what deserves to be called a moronic mistake.
Calling our fatal mistakes experience results not only in the recession of the gravity of the matter but also induces a sense of triviality in us, about the future course of our action.
Some mistakes can just not be correlated to experience. More often than not, life presents us with one shot opportunities and if we miss those, there is no coming back for a second hit; there is no need for the experience because what's lost is lost forever. As is aptly said by Heraclitus,
"No man steps in the same river twice, for it's not the same river and he's not the same man."


What is TypeScript ?
TypeScript is a strongly typed, object oriented, compiled language. TypeScript is a typed superset of JavaScript compiled to JavaScript. In other words, TypeScript is JavaScript plus some additional features. It was designed by Anders Hejlsberg (designer of C#) at Microsoft in 2012. And from the very beginning, the new language began to spread rapidly due to its flexibility and productivity.
Why use TypeScript ?
TypeScript Setup:
We just need to install it with the npm package manager and create a new typescript file
npm install -g typescript
Number:
Number type including binary and hex values
let number: number = 5;
let hex: number = 0xbeef;
let bin: number = 0b0010;
String:
let str: string = "Hello World!";
Boolean:
let falsy: boolean = false;
let truthy: boolean = true;
Single Type:
let str: string = "Hello World!";
Multiple Types:
let multitype: string | number = "Hello World!";
multitype = 20;
Any:
let notSure: any = 4;
notSure = "Hello";
Type assertions
as
let str: any = "Hello";
let strLength = (str as string).length;
<>
let str: any = "Hello";
let strLength = (<string>str).length;
Arrays:
let array: string[] = ["Hello", "World"];
let genericArray: Array<number> = [1, 2, 3];
let multitypeArray: (string | number)[] = ["Hello", 1];
let multidimensionalArray: number[][] = [[1,2], [3,4]];
Tuple:
let tuple: [number, string] = [20, "Hello"];
Enums:
Enums allow us to define a set of named constants. Typescript also provides both numeric and string-based enums.
enum Color {Red,Green,Blue,}
let c: Color = Color.Green; // 1
enum Color {
Red = 1,
Green,
Blue,
}
let colorName: string = Color[2]; // Green
Void:
Void is a little like the opposite of any: the absence of having any type at all. You may commonly see this as the return type of functions that do not return a value:
function warn(): void {
console.log("Warning message");
}
Never:
The never type represents the type of values that never occur:
// Function returning never must not have a reachable end point
function error(message: string): never {
throw new Error(message);
}
Custom types:
type Human = {firstName: string, age: number, height: number}
const human: Human = {firstName: "Pete", age: 32, height: 185}
Parameters and return types:
function add(num1: number, num2: number): number {
return num1 + num2
}
add(2, 5);
add(1); //Error to few parameters
add(5, "2"); //Error the second argument must be a number
Optional properties:
function printName(firstName: string, lastName?: string) {
...
}
printName("Gabriel", "Tanner"); // works correctly
printName("Gabriel"); // works correctly
Default values:
function buildName(firstName: string, lastName = "Smith") {
return firstName + " " + lastName;
}
let result1 = buildName("Bob"); // returns "Bob Smith"
class Greeter {
greeting: string;
constructor(message: string) {
this.greeting = message;
}
greet() {
return "Hello, " + this.greeting;
}
}
let greeter = new Greeter("world");
Inheritance:
class Animal {
move(distanceInMeters: number = 0) {
console.log(`Animal moved ${distanceInMeters}m.`);
}
}
class Dog extends Animal {
bark() {
console.log("Woof! Woof!");
}
}
const dog = new Dog();
dog.bark(); // "Woof! Woof!"
dog.move(10); // "Animal moved 10m."
Access modifiers:
Public by default
class Animal {
public name: string;
public constructor(theName: string) {
this.name = theName;
}
public move(distanceInMeters: number) {
console.log(`${this.name} moved ${distanceInMeters}m.`);
}
}
Private
class Animal {
private name: string;
constructor(theName: string) {
this.name = theName;
}
}
new Animal("Cat").name;
// Property 'name' is private
Protected
class Person {
protected name: string;
constructor(name: string) {
this.name = name;
}
}
class Employee extends Person {
private department: string;
constructor(name: string, department: string) {
super(name);
this.department = department;
}
public getElevatorPitch() {
return `Hello, my name is ${this.name}
and I work in ${this.department}.`;
}
}
let howard = new Employee("Howard", "Sales");
console.log(howard.getElevatorPitch());
// "Hello, my name is Howard and I work in Sales."
console.log(howard.name);
// Error
Readonly
class Octopus {
readonly name: string;
readonly numberOfLegs: number = 8;
constructor(theName: string) {
this.name = theName;
}
}
let dad = new Octopus("Man with the 8 strong legs");
dad.name = "Man with the 3-piece suit";
// Cannot assign to 'name' because it is a read-only property.
Interfaces:
interface Person{
name: string
}
const person: Person = {name: "Gabriel"}
// ok
const person2: Person = {names: "Gabriel"}
// is not assignable to type Person
Conclusion
TypeScript has been increasing in its popularity for the last couple of years. It’s mentioned among the five most promising languages in 2020. Angular, one of the largest frontend frameworks, is using TypeScript. About 60% of JS programmers already use TypeScript, and 22% wish to try.

This project aims to show how improving the health of the natural environment also improves the well-being of local residents of and visitors to the watershed. With input from the local residents we will develop a set of indicators and a map tool to effectively communicate these relationships. This map-based tool will be made available to the public to explore. Ultimately, it will be used in conducting scenario analyses to see how different management decisions affect the well-being of residents.This project addresses requirements of data sharing and monitoring specified in Annex 4 of the Canada-Ontario Agreement (COA). It provides a collaborative mechanism among researchers at York University, and the Credit Valley Conservation Authority (CVC) to monitor environmental management decisions in relation to the human well-being.
Development and maintenance of the Credit Valley Watershed and Well-Being system is led by Professor Martin Bunch out of the SpEAR lab at the Faculty of Environmental Studies at York University. This phase of the project is sponsered by Credit Valley Conservation Authority, Water, Economics, Policy and Governance Network, and Canadian Water Network.
Credit Valley Watershed and Well-Being Browser is a web-distributed geographic information system (web-GIS). It is composed of: (i) Free and Open Source System (FOSS) code written for the Credit Valley Watershed and Well-Being project, (ii) FOSS software modules developed by others and linked together to form the overall Credit Valley Watershed and Well-Being Browser system and (iii) a Googlemaps mashup. Credit Valley Watershed and Well-Being Browser was developed using FOSS development tools. (The only component that may potentially be propriety is the spatial data required to delineate watershed and subwatershed boundaries).

The CVC Watershed and Well-being Browser interface consists of four main sections (Figure 1 below): 1) the Header Bar, 2) the Login tab, 3) Visual header tabs, and 4) the Map Viewer tab. A brief description of these components is provided below, and instructions on how to use the various functions accessible via these interface components can be found in Section 3 (Accessing Credit Valley Watershed and Well-being Browser), Section 4 (Using Primary CVC Watershed and Well-being Browser Interface Components), and Section 5 (Credit Valley Watershed and Well-being Browser Core Functions).
Figure 1: Four main sections of the CVC Watershed and Well-being Browser interface: 1) the Header Bar, 2) the Login Tab, 3) Information Tabs, and 4) the Map Viewer Tab.
The Header Bar runs across the top of the Credit Valley Watershed and Well-Being Browser interface (#1 in Figure 1). Above the Header Bar are the logos of the principle project partners. Clicking on these will open a browser window that loads the home page of these partners. Below the Sponsors is the Project Banner displaying the project name, clicking this banner at anytime will return the user to the home page. The Header Bar extends across the Credit Valley Watershed and Well-Being interface.
The left side of this strip contains drop down menus for Well-Being, Ecosystem Services, and Your Stories tabs. Selecting one of these tabs will bring the user to a map viewer that contains relevant open source information about the subject ranging from written, visual, and geographic information.
Located on the right side of the header bar, the user will find the "Login" and "about" tab. This is where the user will register for or log into their account, retrieving a lost password, or find information about the project itself.
Overall, the Header Bar is a stable component, but when a user is logged in the information at the right of the bar changes to display the username of the currently logged-in user, a logout button and a function to change the user's password.
These tabs are a visual representation of the tabs within the header bar. Clicking one of these tabs will bring the user to written information about the particular topic and where the user is able to find many more resources related to the topic of choice.
My Stories:
The Map Viewer (#4 in Figure 1) is located immediately below the header bar in the middle of the interface, between the Watersheds Info panel and the Search Bar. This is a googlemaps mashup that combines spatial data from maps.google.com (Google Streets, Hybrid, Satellite and Terrain, etc.) with data provided by the Cedit Valley Watershed and Well-Being system (e.g., watershed polygons, subwatershed polygons) and data entered by users (Addresses, overlays in the database). The Map Viewer provides basic geographic information system (GIS) capability to pan, zoom in, zoom out, select an entity, add data, turn on (view) or turn off various data layers, and access data management. On the left side of the map viewer there are functions to draw lines and shapes and to edit layers. In the strip ranging across the top of the map viewer, you will find buttons to reset the Map Viewer window and previous and next map options. On the right hand side of this strip, there is a dropdown menu in which you can select Map Layers where you will find the OverLays you wish to make active. (Some of this functionality operates in conjunction with other interface elements of the Credit Valley Watershed and Well-Being Bowser system). See "Using the Map Viewer" below, for more information.
Many functions of the Credit Valley Watershed and Well-Being system can be accessed by the general public without needing a user account to log in to the system. Only My Story upload, data upload, data editing, and data deleting functions and account management require a user account.
There are two types of accounts in the Watershed and Well-Being Web-GIS system: Volunteer accounts and Administrator accounts. Volunteer accounts are intended for users of the system who participate in providing information about the benefits of local watershed and human health well-being by contributing to open source data and stories about their own experiences. Administrator accounts are intended for personal that need to administer the data generated, assign new accounts, remove and add data, etc.
To log into the Credit Valley Watershed and Well-Being Browser system a user must have a valid user name and password. Valid users can log into the Credit Valley Watershed and Well-Being system by clicking on the "Login" button in the upper right corner of the Watershed and Well-Being interface. In the dialog box that appears, users must enter their username into the "Login Name" field and their password into the "Password" field, then click the "OK" button. Please note that the system will take a couple of seconds to refresh itself after a user logs in.
If you have forgotten your password, you can request a password by clicking the "Forgot Password" button, and entering your Login Name and email address in the dialog box that appears.
Users can log out of the Credit Valley Watershed and Well-Being Browser system by clicking on the "Logout" button at the upper right of the Watershed and Well-Being interface. Please note that the system will take a couple of seconds to refresh itself after a user logs out.
To find a location in the Credit Valley Watershed and Well-Being system: On the strip located on the left side of the Map Viewer, type an address or other location information in the general area of your monitoring station in the "Address / Postal Code" search box. Then click the "Search" button.
Note that you can type in postal codes, street addresses, geographic coordinates, street intersections, etc. Here are some examples that will find York University in Toronto, Ontario, Canada:
Once you submit your address, the system will pan and zoom to that location and place a temporary blue icon there. Allowing the user to then use map layers in Figure 2.2 to select different overlays to find information on their watershed and well-being.
Figure 2: A screen capture of the Credit Valley Watershed and Well-Being Map Viewer (a googlemaps mashup) showing: (1) Address Search Bar, (2) Information Window, (3) Geographic Coordinates and Scale, (4) Interactive Map,(5) Map Tools, (6) Zooming Functions and Map Reset option, (7) and the displayed Map Layers.
Accessing Map information:
Panning (moving around the Map Viewer display):
Zooming in or out (changing the scale): Zoom in or out by clicking on the + (zoom in) or - (zoom out) button in the upper right corner of the Map Viewer window (#6 in Figure 2). Selecting a watershed or subwatershed in the Detail Info Panel to the right of the Map Viewer will cause the selected watershed/subwatershed to be highlighted. Double-clicking will centre and zoom the Map Viewer window on the selected feature (#7 in Figure 2). #1 in Figure 2.1 shows the selected watershed name and #2 in Figure 2.1 shows the subwatersheds belonging to the selected watershed.

linearHypothesis
computes either a finite-sample F statistic or asymptotic Chi-squared
statistic for carrying out a Wald-test-based comparison between a model
and a linearly restricted model. The default method will work with any
model object for which the coefficient vector can be retrieved by
coef
and the coefficient-covariance matrix by vcov
(otherwise
the argument vcov.
has to be set explicitly). For computing the
F statistic (but not the Chi-squared statistic) a df.residual
method needs to be available. If a formula
method exists, it is
used for pretty printing.
The method for "lm"
objects calls the default method, but it
changes the default test to "F"
, supports the convenience argument
white.adjust
(for backwards compatibility), and enhances the output
by the residual sums of squares. For "glm"
objects just the default
method is called (bypassing the "lm"
method). The svyglm
method
also calls the default method.
The function lht
also dispatches to linearHypothesis
.
The hypothesis matrix can be supplied as a numeric matrix (or vector), the rows of which specify linear combinations of the model coefficients, which are tested equal to the corresponding entries in the right-hand-side vector, which defaults to a vector of zeroes.
Alternatively, the hypothesis can be specified symbolically as a character vector with one or more elements, each of which gives either a linear combination of coefficients, or a linear equation in the coefficients (i.e., with both a left and right side separated by an equals sign). Components of a linear expression or linear equation can consist of numeric constants, or numeric constants multiplying coefficient names (in which case the number precedes the coefficient, and may be separated from it by spaces or an asterisk); constants of 1 or -1 may be omitted. Spaces are always optional. Components are separated by plus or minus signs. Newlines or tabs in hypotheses will be treated as spaces. See the examples below.
If the user sets the arguments coef.
and vcov.
, then the computations
are done without reference to the model
argument. This is like assuming
that coef.
is normally distibuted with estimated variance vcov.
and the linearHypothesis
will compute tests on the mean vector for
coef.
, without actually using the model
argument.
A linear hypothesis for a multivariate linear model (i.e., an object of
class "mlm"
) can optionally include an intra-subject transformation matrix
for a repeated-measures design.
If the intra-subject transformation is absent (the default), the multivariate
test concerns all of the corresponding coefficients for the response variables.
There are two ways to specify the transformation matrix for the
repeated measures:
The transformation matrix can be specified directly via the P
argument.
A data frame can be provided defining the repeated-measures factor or
factors
via idata
, with default contrasts given by the icontrasts
argument. An intra-subject model-matrix is generated from the one-sided formula
specified by the idesign
argument; columns of the model matrix
corresponding to different terms in the intra-subject model must be orthogonal
(as is insured by the default contrasts). Note that the contrasts given in
icontrasts
can be overridden by assigning specific contrasts to the
factors in idata
.
The repeated-measures transformation matrix consists of the
columns of the intra-subject model matrix corresponding to the term or terms
in iterms
. In most instances, this will be the simpler approach, and
indeed, most tests of interests can be generated automatically via the
Anova
function.
matchCoefs
is a convenience function that can sometimes help in formulating hypotheses; for example
matchCoefs(mod, ":")
will return the names of all interaction coefficients in the model mod
.
For a univariate model, an object of class "anova"
which contains the residual degrees of freedom
in the model, the difference in degrees of freedom, Wald statistic
(either "F"
or "Chisq"
), and corresponding p value.
The value of the linear hypothesis and its covariance matrix are returned
respectively as "value"
and "vcov"
attributes of the object
(but not printed).
For a multivariate linear model, an object of class
"linearHypothesis.mlm"
, which contains sums-of-squares-and-product
matrices for the hypothesis and for error, degrees of freedom for the
hypothesis and error, and some other information.
The returned object normally would be printed.

Imam Baianonie
Note: Imam Baianonie retired in 2015 after 30 years of service to the community. He was an essential part of building and strengthening the community and will leave a lasting legacy of leadership. May Allah bless him for his hard work and dedication.
Mohammed Baianonie was born September 23, 1952 in Allipo, Syria. For as long as he can remember he has always wanted to study shariah. "I first started to study shariah in the seventh grade," recalled Baianonie. "The school that I attended taught all the basic subjects one learns in public school but added in other subjects such as Shariah and Tafseer."
After graduating from high school, Baianonie attended the University of Damascus. Upon completing his education he became a teacher in the same school he had attended earlier.
"In Syria, being an Imam is not a full time job," said Imam Baianonie. "Therefore, I used my education in Shariah to be a teacher. I also studied with other Shuyukh in different masajid."
In November of 1985, Imam Baianonie was invited by the MSA of NC State to spend a weekend in Raleigh. He met with the MSA president and other members who requested him to move to Raleigh to fulfill the position of Imam. "When I first came to Raleigh they had not even finished building the first floor of the old masjid," remembered Imam Baianonie. "They had the foundation down, but the walls had not even been built yet."
He accepted the offer, becoming the first Imam of the Islamic Association of Raleigh, the position he still holds today. Unlike in Syria, being an Imam for the IAR is a full time job with many responsibilities. "There is no such thing as office hours when you are an Imam," said Imam Baianonie. "I have to be available day and night to serve the Muslim community's needs.
Leading the prayer is not my only job as an Imam. My jobs also include counseling spouses and families, giving educational programs, performing marriages, performing janazas, and all the other needs of the community." Imam Baianonie also participates in a Fatwa hotline established by IANA in 1995.
The hotline is open five days a week from one to three and Imam Baianonie covers Tuesdays. Though all these jobs may seem overwhelming, Imam Baianonie wants to do even more. His long-term goal is to establish a complete Imam training school in Raleigh. So far, the first step towards this goal has been attained with the approval of the community to begin Al-Bayan School for Qur'an Memorization.
When it comes to free time Imam Baianonie enjoys a good book. "I love reading," said Imam Baianonie. "Once I get started I could read for hours and hours. I like to read all the new Islamic books that come out. I learn new information and at the same time can evaluate these books so I can recommend them later or use them in my curriculum. Most of the books I read are in Arabic."
There is a large variety of Hadith but Imam Baianonie especially likes the Forty Hadith Nawawiyah and the Forty Qudsi Hadiths because, "they were selected by Nawawi and they go over the main issues if the Deen." He also finds special merit in reading suratul Ikhlas, Al-Fatiha, A-Nas, Al-Falaq, and Ayatul Kursi. "All the Qura'an is special but the Prophet (SAW) described these surahs as having significant meritsl," said Imam Baianonie.
Imam Baianonie also enjoys a good meal; and he is not very picky about the type of food. "I enjoy almost all halal foods," said Imam Baianonie. "When I am hungry I will eat all kinds of food as long as the meal is prepared well."
Many changes have occured during the Imam's tenure at our masjid. Children do not stay young forever. This fact has not escaped Imam Baianonie's thoughts. When it comes to special experiences at the Masjid, the youth are at the top of his list. "Something that holds a lot of meaning for me is when I see the children that I have watched grow for fifteen years graduate and get married," said Imam Baianonie. "It reminds me of when you have a plant that grows and starts to flower." The affection he has for the youth of Raleigh is something that they also feel in return.
Imam Baianonie is well known amongst the young members of the IAR, and he is well liked by all. "I love the Imam," exclaimed Heba AbdelBaky. "The fact that he is honest, neutral, patient, straight forward, and not pushy makes him a great Imam. I trust his judgment because he always goes back to the Qura'an and Sunnah to give you your options. Besides that there is the fact that he is always so calm and patient which makes it all the easier to talk to him."
Shadi Salama is in agreement with AbdelBaky on this point. "Without a doubt the Imam is an extremely knowledgeable person who is very familiar and aware of all aspects of the Deen and how they affect the Muslim Ummah," said Salama. "He gives clear and concise answers to questions that are presented to him. He is very familiar with most of the schools of thought. And he is actually pretty funny when he jokes with you."
From his years of experience Imam Baianonie has some advice to share with the youth. "Muslim youth can be good Muslims and at the same time enjoy their worldly life, especially if they recognize the limits of Shariah," said Imam Baianonie. "The youth should not think that they will always be young. They have to prepare for the future. The Prophet (SAW) facilitated the youth to build the first Islamic State."
According to Imam Baianonie the years he has spent in the community have been worth more than he could give. Though he already gives most of his time he wants to give even more. "There are so many opportunities that Allah has given us in this country that I wish I could do more for the community," said Imam Baianonie. "In the United States we have freedoms that we do not have anywhere else in the world. I am a person who likes freedom and that is why I am here. We need to use this freedom in the best way, however. We need to plant our roots in the ground and especially focus on Islamic education."
"May Allah Bless Imam Baianonie and reward him for all his efforts in this life and in the Hereafter."

This guide will provide instruction on how to build an online repository where the vagrant boxes can be hosted and easily downloaded. This is NOT an in depth apache or http guide, but it will provide enough instruction to get a web server up and running with a few pages and downloadable content.
After apache is installed, we will want to make sure that it can be started. To check the status of the apache service, enter the command:
sudo systemctl status httpd
To start the apache service:
systemctl start
And then check the status again to make sure it is running
Apache can be stopped with:
systemctl stop httpd
Then check the status again to be sure it stopped
While apache is running it will look in the doccument root for html files.
the typical web root is
/var/www/html
For this project there only a few web pages running on apache. We have:
- an index (the home page) - a downloads page - Documentation pages.
the index acts as a home page for the service. It contains a brief description of the project and links to other pages.
this is where links to the downloadable files will go. In this project there are links to boxes, Vagrantfiles, and iso files. It is important to have the link pointing to the actual path of the file you are linking, and that file needs to have adequate permissions in order to be downloaded
A simple way to ensure files are in directories with correct permissions is to house them in sub-folders within the doccument root.
For this project there are sub-folders for:
- boxes - iso_downloads - maintenance_docs - pictures - Vagrant recipies
These pages (packer and vagrant on the home page) are general "how to use" pages.
They contain info about how to install and use the tools, as well as useful screenshots.

nope
Hmmm.... it's "Mario nope" hard. That's unfortunate.
We have the hover information, and olean files know everything about source locations. So I was hoping that we could run some substitution over the source files...
you might be able to exploit go to definition support, but that's exactly the sort of thing that not having an external parser causes
It will require some new lean API
I've actually given some thought to how to do such refactorings in the Lean 3 parser, even without a concrete syntax tree. You could change the scanner to output each read token to some output stream before reading the next token from the input, which gives the parser (which does name resolution in Lean 3) a chance to modify that token before calling into the scanner again...
Could it send the data to vscode instead? I know vscode / LSP has a rename option, and it seems like file editing is better done there

Joshua turned down $50m to fight Wilder
by Agency ReportAnthony Joshua turned down the chance to fight Deontay Wilder in 2018, according to Shelly Finkel.
The American, who co-manages Wilder alongside the legendary Al Haymon, was at the negotiation table with Matchroom Boxing in an attempt to organise a world heavyweight title unification bout.
At the time of talks, Joshua had conclusively beaten Joseph Parker on points to claim the WBO strap, while Wilder had just defended his WBC belt.
SEE ALSO: 23-year-old model battles stage-3 melanoma cancer
However, talks over a potential match-up never materialised and both sides left the negotiating table feeling frustrated.
Joshua went on to knock out mandatory WBA challenger Alexander Povetkin at Wembley before the ‘Bronze Bomber’ took on Tyson Fury in a pulsating, yet controversial draw.

The Early Years Foundation Stage (EYFS) comprises of Reception, Nursery and Pre-Nursery aged Children from birth to 4 years of age.
The EYFS Curriculum guides the learning and teaching process and helps us establish an optimum learning environment in our classes. We believe that to engage, achieve and make positive contributions, students must be healthy, secure and safe. We value these needs and understand their contribution to the development of happy students in an enjoyable, encouraging and stimulating atmosphere.
Our learning environments combine high standards of materials with a broad and rich curriculum. We focus on Inquiry-based Learning, using a variety of play-based and structured activities, striking a fine balance between both teacher-led and student-initiated play. This is because play underpins all development and learning for young children: most children play spontaneously and it is through play that they develop intellectually, creatively, physically, socially and emotionally.

https://digi.ninja/projects/bucket_finder.php - Amazon S3 bucket brute finder
Bucket Finder
This project goes alongside my blog post Whats In Amazon's Buckets, read through that for more information on what is going on behind the scenes.
This is a fairly simple tool to run, all it requires is a wordlist and it will go off and check each word to see if that bucket name exists in the Amazon's S3 system. Any that it finds it will check to see if the bucket is public, private or a redirect.
Public buckets are checked for directory indexing being enabled, if it is then all files listed will be checked using HEAD to see if they are public or private. Redirects are followed and the final destination checked. All this is reported on so you can later go through and analyse what has been found.
Installation
I don't think it needs anything more than the built in modules so you shouldn't need to install any gems. Just grab the file, make it executable and run it.
I've tested it in Ruby 1.8.7 and 1.9.1 so there should be no problems with versions.
Usage
Basic usage is simple, just start it with a wordlist:
./bucket_finder.rb my_words
and it will go off and do your bidding.
You can specify which region you want to run the initial check against by using the --region parameter:
./bucket_finder.rb --region ie my_words
The script will follow all redirects anyway so even if left at default, US Standard, everything will be found that can be found but if most of the buckets you are finding are in a different region then you'll be doing a lot of redirects so doubling your network traffic.
You can also specify the --download option to download all public files found. Be careful with this as there are a lot of large files out there. I'd personally do the general search then only use this option with a select subset of bucket names:
./bucket_finder.rb --download --region ie my_words
The files are downloaded into a folder with the bucket name and then the appropriate structure from the bucket.
As some people are having trouble piping the output to files or other apps I've added a logging option to send all output to a file. To use this just use the --log-file parameter:
./bucket_finder.rb --log-file bucket.out my_words
