B is a new computer language designed and implemented at Murray Hill. It runs and is actively supported and documented on the H6070 TSS system at Murray Hill.
B is particularly suited for non-numeric computations, typified by system programming. These usually involve many complex logical decisions, computations on integers and fields of words, especially characters and bit strings, and no floating point. B programs for such operations are substantially easier to write and understand than GMAP programs. The generated code is quite good. Implementation of simple TSS subsystems is an especially good use for B.
B is reminiscent of BCPL [2] , for those who can remember. The original design and implementation are the work of K. L. Thompson and D. M. Ritchie; their original 6070 version has been substantially improved by S. C. Johnson, who also wrote the runtime library.
This memo is a tutorial to make learning B as painless as possible. Most of the features of the language are mentioned in passing, but only the most important are stressed. Users who would like the full story should consult A User's Reference to B on MH-TSS, by S. C. Johnson [1], which should be read for details anyway.
We will assume that the user is familiar with the mysteries of TSS, such as creating files, text editing, and the like, and has programmed in some language before.
Throughout, the symbolism (->n) implies that a topic will be expanded upon in section n of this manual. Appendix E is an index to the contents.
main( ) { -- statements -- } newfunc(arg1, arg2) { -- statements -- } fun3(arg) { -- more statements -- }
Functions are totally independent as far as the compiler is concerned, and main need not be the first, although execution starts with it. This program has two other functions: newfunc has two arguments, and fun3 has one. Each function consists of one or more statements which express operations on variables and transfer of control. Functions may be used recursively at little cost in time or space (->30).
Most statements contain expressions, which in turn are made up of operators, names, and constants, with parentheses to alter the order of evaluation. B has a particularly rich set of operators and expressions, and relatively few statement types.
The format of B programs is quite free; we will strive for a uniform style as a good programming practice. Statements can be broken into more than one line at any reasonable point, i.e., between names, operators, and constants. Conversely, more than one statement can occur on one line. Statements are separated by semicolons. A group of statements may be grouped together and treated as a single statement by enclosing them in {}; in this case, no semicolon is used after the '}' . This convention is used to lump together the statements of a function.
(a) SYSTEM? filsys cf bsource,b/1,100/ (b) SYSTEM? filsys cf bhs,b/6,6/,m/r/ (c) SYSTEM? [create source program with any text editor] (d) SYSTEM? ./bj (w) bsource bhs (e) SYSTEM? /bhs
You may from time to time get error messages from the B compilers These look like either of
ee n ee name n
main( ) { auto a, b, c, sum; a = 1; b = 2; c = 3; sum = a+b+c; putnumb(sum); }
putnumb is a library function of one argument, which will print a number on the terminal (unless some other destination is specified (->28)). The code for a version of putnumb can be found in (->30). Notice that a function is invoked by naming it, followed by the argument(s) in parentheses. There is no CALL statement as in Fortran.
The arithmetic and the assignment statements are much the same as in Fortran, except for the semicolons. Notice that we can put several on a line if we want. Conversely, we can split a statement among lines if it seems desirable - the split may be between any of the operators or variables, but not in the middle of a variable name.
One major difference between B and Fortran is that B is a typeless language: there is no analog in B of the Fortran IJKLMN convention. Thus a, b, c, and sum are all 36-bit quantities, and arithmetic operations are integer. This is discussed at length in the next section (->5).
Variable names have one to eight ascii characters, chosen from A-Z, a-z, ., _, 0-9, and start with a non-digit. Stylistically, it's much better to use only a single case (upper or lower) and give functions and external variables (->7) names that are unique in the first six characters. ( Function and external variable names are used by batch GMAP, which is limited to six character single-case identifiers. )
The statement "auto ..." is a declaration, that is, it defines the variables to be used within the function. auto in particular is used to declare local variables, variables which exist only within their own function (main in this case). Variables may be distributed among auto declarations arbitrarily, but all declarations must precede executable statements. All variables must be declared, as one of auto, extrn (->7), or implicitly as function arguments (->8).
auto variables are different from Fortran local variables in one important respect - they appear when the function is entered, and disappear when it is left. They cannot be initialized at compile time, and they have no memory from one call to the next.
All arithmetic in B is integer, unless special functions are written. There is no equivalent of the Fortran IJKLMN convention, no floating point, no data types, no type conversions, and no type checking. Users of double-precision complex will have to fend for themselves. (But see ->32 for how to call Fortran subroutines.)
The arithmetic operators are the usual '+', '-', '*', and '/' (integer division). In addition we have the remainder operator '%':
x = a%b
Since B is often used for system programming and bit-manipulation, octal numbers are an important part of the language. The syntax of B says that any number that begins with 0 is an octal number (and hence can't have any 8's or 9's in it). Thus 0777 is an octal constant, with decimal value 511.
main( ) { auto a; a= 'hi!'; putchar(a); putchar('*n' ); }
The sequence "*n" is B Jargon for "newline character", which, when printed, skips the terminal to the beginning of t:e next line. No output occurs until putchar encounters a "*n" or the program terminates. Omission of the "*n", a common error, causes all output to appear on one line, which is usually not the desired result. There are several other escapes like "*n" for representing hard-to-get characters (->Appendix B). Notice that "*n" is a single character: putchar('hi!*n') prints four characters (the maximum with a single call).
Since B is a typeless language, arithmetic on characters is quite legal, and even makes sense sometimes:
c = c+'A'-'a';
main( ) { extrn a, b, c; putchar(a); putchar(b); putchar(c); putchar('!*n'); } a 'hell'; b 'o, w'; c 'orld';
External storage is static, and always remains in existence, so it can be initialized. (Conversely, auto storage appears whenever the function is invoked, and disappears when the function is left. auto variables of the same name in different functions are unrelated. ) Initialization is done as shown: the initial value appears after the name, as a constant. We have shown character constants; other forms are also possible. External variables are initialized to zero if not set explicitly.
main( ) { extrn a,b,c,d; put2char(a,b) ; put2char(c,d) ; } put2char(x,y) { putchar(x); putchar(y); } a 'hell'; b 'o, w'; c 'orld'; d '!*n';
put2char( 'hell','o, w'); etc.
main( ) { auto c; c= getchar(); putchar(c); }
== equal to (".EQ." to Fortraners) != not equal to > greater than < less than >= greater than or equal to <= less than or equal to
main( ) { auto c; read: c= getchar(); putchar(c); if(c != '*n') goto read; } /* loop if not a newline */
read is a label - a name followed by a colon ':', also just as in PL/I. A statement can have several labels if desired. (Good programming practice dictates using few labels, so later examples will strive to get rid of them.) The goto references a label in the same function.
The if statement is one of four conditionals in B. (while (->14), switch (->26), and "?:" (->16) are the others.) Its general form is
if (expression) statement
if(a<b) { t = a; a = b; b = t; }
As a general rule in B, anywhere you can use a simple statement, you can use any compound statement, which is just a number of simple or compound ones enclosed in {}. Compound statements are not followed by semicolons.
The ability to replace single statements by complex ones at will is one thing that makes B much more pleasant to use than Fortran. Logic which requires several GOTO's and labels in Fortran can be done in a simple clear natural way using the compound statements of B.
read: c = putchar(getchar()); if (c != '*n') goto read;
Even better, if c won't be needed later, we can say
read: if (putchar(getchar()) != '*n') goto read;
while ((c=getchar()) != '*n') putchar(c);
while (expression) statement
(a) evaluate the expression (b) if its value is true (i. e., not zero), do the statement and return to (a)
Notice that we used an assignment statement "c=getchar()'" within an expression. This is a handy notational shortcut, usually produces better code, and is sometimes necessary if a statement is to be compressed. This works because an assignment statement has a value, just as any other expression does. This also implies that we can successfully use multiple assignments like
x = y = f(a)+g(b)
c = getchar() != '*n'
main( ) { auto c; while (1) { while ( (c=getchar()) != ' ') if (putchar(c) == '*n') exit(); putchar( '*n' ); while ( (c=getchar()) == ' '); /* skip blanks */ if (putchar(c)=='*n') exit(); /* done when newline */ } }
Line four fetches a character, and if it is non-blank, prints it, and uses the library function exit to terminate execution if it's a newline. Note the use of the assignment within an expression to save the value of c.
Line seven skips over multiple blanks. It fetches a character, and if it's blank, does the statement ';'. This is called a null statement - it really does nothing. Line seven is just a very tight loop, with all the work done in the expression part of the while clause.
The slightly odd-looking construction
while(1){ --- }
if (expression) statement else statement2
if (a<b) x=a; else x=b;
if(---) { ----- ----- } else if(---) { ----- ----- } else if(----) { ----- ----- }
The conditions are tested in order, and exactly one block is executed - the first one whose if is satisfied. When this block is finished, the next statement executed is the one after the last "else if" block.
B provides an alternate form of conditional which is often more concise and efficient. It is called the "conditional expression" because it is a conditional which actually has a value and can be used anywhere an expression can. The last example can best be expressed as
x = a<b ? a : b;
auto k; k = 0; while (getchar() != '*n') ++k;
k++
x = ++k
x = k++
Similarly, the unary decrement operator '--' can be used either before or after a variable to decrement by one.
c = o; i = 36; while ((i = i-9) >= 0) c = c | getchar()<<i;
The other logical operators are AND '&', logical right shift '>>', exclusive OR '^', and 1's complement '~'.
x = ~y&0777
x = x&077
The order of evaluation of unparenthesized expressions is determined by the relative binding strengths of the operators involved (-> Appendix D).
An unusual feature of B is that the normal binary operators like '+', '-', etc. can be combined with the assignment operator = to form new assignment operators. For example,
x =- 10
x = -10
x =- 10
x=-10
Because assignment operators have lower binding strength than any other operator, the order of evaluation should be watched carefully:
x = x<<y|z
x =<< y|z
The character-packing example can now be written better as
c= 0; i = 36; while ((i =- 9) >= 0) c =| getchar()<<i;
A vector is a set of consecutive words, somewhat like a one-dimensional array in Fortran. The declaration
auto v[10];
sum = o; i = 0; while (i<=n) sum =+ V[i++];
i = -1; while (v[++i]);
Vectors can of course be external variables rather than auto. We declare v external within the function (don't mention a size) by
extrn v;
v[10];
v[10] 'hi!', 1, 2, 3, 0777;
To understand all the ramifications of vectors, a digression into addressing is necessary. The actual implementation of a vector consists of a word v which contains in its right half the address of the 0-th word of the vector; i.e., v is really a pointer to the actual vector.
This implementation can lead to a fine trap for the unwary. If we say
auto u[10], v[10]; --- u = v; v[0] = ... v[1] = ... ---
The fact that vector elements are referenced by a pointer to the zeroeth entry makes subscripting trivial - the address of v[i] is simply v+i. Furthermore, constructs like v[i][j] are quite legal: v[i] is simply a pointer to a vector, and v[i][j] is its j-th entry. You have to set up your own storage, though.
To facilitate manipulation of addresses when it seems advisable, B provides two unary ad~ress operators, '*' and '&'. '&' is the address operator so &x is the address of x, assuming it has one. '*' is the indirection operator; "*x" means "use the content of x as an address."
Subscripting operations can now be expressed differently:
x[0] is equivalent to *x x[1] is equivalent to *(x+1) &x[0] is equivalent to x
A string in B is in essence a vector of characters. It is written as
"this is a string"
"hello"
Some characters can only be put into strings by "escape sequences" (-> Appendix B ). For instance, to get a double quote into a string, use '*"', as in
"He said, *"Let's go.*""
a "hello"; b "world'*; v[2] "now is the time", "for all good men", "to come to the aid of the party";
Because strings are vectors, writing "s1=s2" does not copy the characters in s2 into s1, but merely makes s1 point to s2. To copy s2 into s1, we can use char and lchar in a function like strcopy:
strcopy(sl ,s2){ auto i; i = 0; while (lchar(sl,i,char(s2,i)) != '*e') i++; }
How do we arrange that a function like char returns a value to its caller? Here is char:
char(s, n){ auto y,sh,cpos; y = s[n/4]; /* word containing n-th char */ cpos = n%4; /* position of char in word */ sh = 27-9*cpos; /* bit positions to shift */ y = (y>>sh)&0777; /* shift and mask all but 9 bits */ return(y); /* return character to caller */ }
char(s,n) return((s[n/4]>>(27-9*(n%4)))&0777);
concat(s,al,a2,...,a10) concatenates the zero or more strings ai into one big string s, and returns s (which means a pointer to S[0]). s must be declared big enough to hold the result (including the terminating '*e').
getstr(s) fetches the entire next line from the input unit into s, replacing the terminating '*n' by '*e'. In B, it is
getstr(s){ auto c,i; while ((c=getchar()) != '*n') lchar(s,i++,c); lchar(s,i,'*e'); return(s) ; }
auto s[20] ; putstr(getstr(s)); putchar('*n');
loop: switch (c=getchar()){ pr: case 'p': /* print */ case 'P': print(); goto loop; case 's': /* subs */ case 'S': subs() ; goto pr; case 'd': /* delete */ case 'D': delete(); goto loop; case '*n': /* quit on newline */ break; default: error(); /* error if fall out */ goto loop; }
The general form of a switch is
switch (expression) statement
case constant:
If no match is found, execution continues at the statement labeled default: if it exists; if there is no match and no default, the entire statement part of the switch is skipped.
The break statement forces an immediate transfer to the next statement after the switch statement, i.e., the statement after the {} which enclose the statement part of the switch. break may also be used in while statements in an analogous manner. break is a useful way to avoid useless labels.
In this section, we point to the function printf, which is used for producing formatted IO. This function is so useful that it is actually placed in Appendix C for ready reference.
File IO is described in much more detail in [1], section 8. This discussion does only the easy things.
Basically, all IO in B is character-oriented, and based on getchar and putchar. By default, these functions refer to the terminal, and IO goes there unless explicit steps are taken to divert it. The diversion is easy and systematic, so IO unit switching is quite feasible.
At any time there is one input unit and one output unit; getchar and putchar use these for their input and output by implication. The unit is a number between -1 and 10 (rather like Fortran file numbers). The current values are stored in the external variables rd.unit and wr.unit so they can be changed easily, although most programs need not use them directly. When execution of a B program begins, rd.unit is 0, which means "read from terminal", and wr.unit is -1, meaning "write on terminal".
To do input from a file, we set rd.unit to a value, and assign a file name to that unit. Then, until the assignment or the value is changed, getchar reads its characters from that file. Thus, to open for reading an ascii permanent file called "cat/file", as input unit 5,
openr(5, "cat/file")
Writing is much the same:
openw(u,s)
If the IO unit mentioned in openr or openw is already open, it is closed before the next use. That is, any output for output files is flushed and end of file written; any input from input files is thrown away. Files are also closed this way upon normal termination.
Programs which have only one input and one output unit open simultaneously need not reference rd.unit and wr.unit explicitly, since the opening routines will do It automatically. Otherwise, don't forget to declare them in an extrn statement.
The function flush closes the current output unit without writing a terminating newline character. If this file is the terminal, this is the way to force a prompting question before reading a response on the same line:
putstr("old or new?"); flush(); getstr(s);
old or new?
File names may only be "cat/file", "/file", or "file": no permissions, passwords subcatalogs or alternate names are allowed. File names containing a '/' are assumed to be permanent files; if you try to open a permanent file which is already accessed, it is released and reaccessed. If it can't be found, the access fails. A file name without '/' may or may not be a permanent file, so if a file of this name is already accessed, it is used without question. If it is not already accessed, a search of the user's catalog is made for it. If it can't be found there either, and writing is desired, a temporary file is made.
The function reread is used to re-read a line. Its primary function is that if it is called before the first call to getchar, it retrieves the command line with which the program was called.
reread(); getstr(s);
TSS users can easily execute other TSS subsystems from within a running B program, by using the library function system. For instance,
system("./rj (w) ident;file");
./rj (w) ident;file
We can also use printf (->Appendix C) to write on the "system" IO unit, which is predefined as -1. All output written on unit -1 acts as if typed at "SYSTEM?" level. Thus,
extrn wr.unit; --- wr.unit = -1; opts = "(w)"; fname = "file"; printf("./rj %s ident;%s*n", opts,fname');
Because of serious design failings in TSS, there is generally no decent way to send more than the command line as input to a program called this way, and no way to retrieve output from it.
putnumb(n) { auto a; if(a=n/10) /* assignment, not equality test */ putnumb(a); /* recursive */ putchar(n%10 + '0'); }
There is a subtlety in function usage which can trap the unsuspecting Fortran programmer. Argument passing is call by value", which means that the called function is given the actual values of its arguments, and doesn't know their addresses. This makes it very hard to change the value of one of the input arguments!
For instance, consider a function flip(x,y) which is to interchange its arguments. We might naively write
flip(x,y){ auto t; t = x; x = y; y = t; }
flip(&a,&b);
flip(x,y){ auto t; t = *y; *x = *y; *y = t; }
As we mentioned, B doesn't have floating point, multi-dimensional arrays, and similar things that Fortran does better. A B program, callf, allows B programs to call Fortran and GMAP subroutines, like this:
callf(name, a1,a2, . . .,a10)
There are some restrictions on callf, related to the "call by value" problem mentioned above. First, variables that are not vectors or strings must be referenced by address: use "&x" instead of "x" as an argument. Second, no constants are allowed among the arguments, because the construction "&constant" is illegal in B. We can't say
tod = callf(itimez,&0)
t=0; tod = callf(itimez,&t) ;
s = callf(sin,&x)
callf(sin2,&x,&s)
subroutine sin2(x,y) y = sin(x) return end

The Professor
by Charlotte Brontë
The Professor was Charlotte Brontë's first novel, written before Jane Eyre but rejected by publishers until after her death. The book tells the story of a young man named William Crimsworth, from his formative years to his appointment as a teacher at an all-girls school. The story is based upon Brontë’s experiences in school.

HTTP & Authentication
This section will cover HTTP related testing and user identity authentication.
HTTP requests
Sometimes we need to process the HTTP request in the controller action. Take a look at the HTTP Post overload of the "AddressAndPayment" action in the "CheckoutController":
// action code skipped for brevity
var formCollection = await HttpContext.Request.ReadFormAsync();
try
{
if (string.Equals(formCollection["PromoCode"].FirstOrDefault(), PromoCode,
StringComparison.OrdinalIgnoreCase) == false)
{
return View(order);
}
// action code skipped for brevity
The action reads the form and checks for an input named "PromoCode". If it does not equal "FREE", the action returns its view with the same order provided by the form. Let's test this logic!
Go to the "MusicStore.Test.csproj" file and add "MyTested.AspNetCore.Mvc.Http" as a dependency:
<!-- Other ItemGroups -->
<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore.App" />
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.0.1" />

<PackageReference Include="xunit.runner.visualstudio" Version="2.4.0" />
</ItemGroup>
<!-- Other ItemGroups -->
This package will provide you with additional methods - two of them are "WithHttpContext" and "WithHttpRequest". We will use the second one - it provides a fast way to set up every single part of the HTTP request.
Go to the "CheckoutControllerTest" class and add the following test:
[Fact]
public void AddressAndPaymentShouldRerurnViewWithInvalidPostedPromoCode()
=> MyController<CheckoutController>
.Instance()
.WithHttpRequest(request => request // <---
.WithFormField("PromoCode", "Invalid"))
.Calling(c => c.AddressAndPayment(
From.Services<MusicStoreContext>(),
With.Default<Order>(),
CancellationToken.None))
.ShouldHave()
.InvalidModelState()
.AndAlso()
.ShouldReturn()
.View(result => result
.WithModel(With.Default<Order>()));
We have successfully tested that with an invalid promo code in the request form, our action should return the same view with the proper model. The "WithHttpRequest" method allows you to add form fields, files, headers, body, cookies and more. We will see more of it when we cover route testing.
Authentication
Now let's take a look at the "Complete" action in the same controller:
// action code skipped for brevity
var userName = HttpContext.User.Identity.Name;
bool isValid = await dbContext.Orders.AnyAsync(
o => o.OrderId == id &&
o.Username == userName);
if (isValid)
{
return View(id);
}
else
{
return View("Error");
}
// action code skipped for brevity
By default tests do not have an authenticated user identity. Write this theory in the "CheckoutControllerTest", run it, and see for yourself:
[Theory]
[InlineData(1)]
public void CompleteShouldReturnViewWithCorrectIdWithFoundOrderForTheUser(int orderId)
=> MyController<CheckoutController>
.Instance()
.WithData(new Order
{
OrderId = orderId,
Username = "TestUser"
})
.Calling(c => c.Complete(
From.Services<MusicStoreContext>(),
orderId))
.ShouldReturn()
.View(result => result
.WithModel(orderId));
It fails. Obviously, we need an authenticated user to test this action. We can attach it to the "HttpContext" but let's make it easier. Head over to the "MusicStore.Test.csproj" file again and add "MyTested.AspNetCore.Mvc.Authentication":

<!-- Other ItemGroups -->
"WithUser" method will be added to the fluent API. You can use it to set identifier, username, roles, claims, and identities. But for now call it empty like this:
[Theory]
[InlineData(1)]
public void CompleteShouldReturnViewWithCorrectIdWithFoundOrderForTheUser(int orderId)
=> MyController<CheckoutController>
.Instance()
.WithUser()
.WithData(new Order
{
OrderId = orderId,
Username = "TestUser"
})
.Calling(c => c.Complete(
From.Services<MusicStoreContext>(),
orderId))
.ShouldReturn()
.View(result => result
.WithModel(orderId));
You will receive a passing test because the default authenticated user has "TestId" identifier and "TestUser" username. Change the order's "Username" property to "MyTestUser" and you will need to provide the username of the identity in order to make the test pass again:
[Theory]
[InlineData(1, "MyTestUser")]
public void CompleteShouldReturnViewWithCorrectIdWithFoundOrderForTheUser(
int orderId,
string username)
=> MyController<CheckoutController>
.Instance()
.WithUser(user => user // <---
.WithUsername(username))
.WithData(new Order
{
OrderId = orderId,
Username = username
})
.Calling(c => c.Complete(
From.Services<MusicStoreContext>(),
orderId))
.ShouldReturn()
.View(result => result
.WithModel(orderId));
Of course, we also need to test the result when the order is not for the currently authenticated user. In this case, we need to assert the "Error" view, but to do it fluently open the "MusicStore.Test.csproj" file again and add "MyTested.AspNetCore.Mvc.Views.ActionResults" package:
<!-- Other ItemGroups -->
<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore.App" />

<PackageReference Include="xunit.runner.visualstudio" Version="2.4.0" />
</ItemGroup>
<!-- Other ItemGroups -->
The "Views.ActionResults" package contains additional useful extension methods for view related results.
Now add this test and it should pass:
[Theory]
[InlineData(1)]
public void CompleteShouldReturnErrorViewWithInvalidOrderForTheUser(int orderId)
=> MyController<CheckoutController>
.Instance()
.WithUser(user => user
.WithUsername("InvalidUser"))
.WithData(new Order
{
OrderId = orderId,
Username = "MyTestUser"
})
.Calling(c => c.Complete(
From.Services<MusicStoreContext>(),
orderId))
.ShouldReturn()
.View(result => result
.WithName("Error")); // <---
HTTP Response
Sometimes we may manipulate the HTTP response directly in the controller action. For example, to add a custom header. The Music Store web application does not have such logic, but we can take any action and validate whether it returns 200 (OK) status code just for the sake of seeing the syntax.
Create a "HomeControllerTest" class and add the following test:
[Fact]
public void AccessDeniedShouldReturnOkStatusCodeAndProperView()
=> MyController<HomeController>
.Instance()
.Calling(c => c.AccessDenied())
.ShouldHave()
.HttpResponse(response => response // <---
.WithStatusCode(HttpStatusCode.OK))
.AndAlso()
.ShouldReturn()
.View(result => result
.WithName("~/Views/Shared/AccessDenied.cshtml"));
The "HttpResponse" method allows assertions of every part of the HTTP response - body, headers, cookies, etc. For example, if you add this line:
.ShouldHave()
.HttpResponse(response => response
.ContainingHeader("InvalidHeader") // <---
.WithStatusCode(HttpStatusCode.OK))
.AndAlso()
You will receive a nice little error message (as always):
When calling AccessDenied action in HomeController expected HTTP response headers to contain header with 'InvalidHeader' name, but such was not found.
Cool! :)
Section summary
Well, these were easier than the last section's test services. While the request testing is more suitable for other components, authentication plays a significant role in the actions' logic.
You have learned quite a lot. Let's take a break from the code and learn more about the Licensing of the testing framework.

Power Of NeuroGaming
During the summer of 2018 I worked for RAD Lab's PoNG program as a Job Coach and Team Leader. For the PoNG program, RAD Lab hired 25 individuals, the majority of whom were diagnosed with ASD, to create video games that the lab would used in the future. With the role of Job Coach I provided workpace support to five of these individuals, with the goal of helping them develop interpersonal and professional skills. In the role of Team Leader, I managed five individuals who worked together to develop a game targeted for toddlers that would develop eye-fixation accuracy.
My team of five interns were given the task of creating a video game for toddlers with Autism. The game focused of training fixation abilities through a light-hearted carnival game. In the game, the toddler uses their gaze to track balloons that are spawned on the screen. When they fixate on the balloon long enough, it pops. As levels advance, balloons are spawned faster and more balloons have to be popped to advance to the next level.


Some additional options (though not everything possible when using the plugin directly) may be applied by adding further predefined class names to the element or by adding data-attributes of certain names:
- Simplest usage: Insert an HTML element (usually
span
) withclass="progresspie"
and with a number ranging from 0 to 100 als its only content. In this case the pie will be prepended to the number in the default color (grey), e.g.55
- Use
class="progressring"
instead, if you prefer the ring display over the pie display. - Add class
color
to activate the default red-yellow-green-color-scheme for dynamically coloring the pie depending on the value, e.g.55
- Add one of the classes
red
orgreen
for constant red or green color, e.g.55
- To apply a constant user-defined color, insert an attribute named
data-piecolor
with the color code or name, e.g.55
- To apply a user-defined dynamic color (defined via a self-written JavaScript function), you may add the attribute
data-piecolor-function
. The attribute value (a string) must evaluate to a function which takes a number (0..100) and returns a string describing a color. This attribut value could be the function code itself, but it's usually better to just state the name of a function defined in a JavaScript block, e.g.55
- By default the image is vertically aligned at the bottom of the element. For inline elements like span that is the bottom of the line.
In some cases you might want to vertically center the image inside the element (for instance if the line is higher than the text, which may
be achieved with setting
line-height
). For vertical centering add the classvcenter
, e.g.55
- If you add the attribute
data-percent
to a .progresspie-element, the value of that attribute is used instead of the element's content e.g.
- Add the class
busy
to the element if you don't want to display a percent value, but only want to indicate your system is busy without measuring the progress. In this case a clockwise rotation animation is inserted: either a small rotating pie slice (if combined with classprogresspie
) or a thins ring with a rotating gap in it (if combined with classprogressring
). - You may add the attribute
data-input
to specify a jQuery selector for an input element. If you do so, the plug-in will not only read the percent value from the specified input (using jQuery'sval()
method), but it will also react to anychange
event of that input by updating the chart to reflect the new value.
Normally you don't have to call any JS function, the drawing function gets automatically applied once for each element of class progresspie or progressring
when the document is loaded. Manual calls may be triggered for updates: Overwrite the content of a progresspie element with a new value
(removing the previously rendered pie) and then call progressPies.draw for updating all elements of class progresspie
with missing SVGs.
- Source:
Members
(static) colorByPercent
This is an alias for / link to the original plugin function $.fn.progressPie.colorByPercent
.
This may be used, if you want to write your own color functions which call the colorByPercent function with modified values.
If you are using this module anyway, calling progressPies.colorByPercent
is simply a bit shorter and prettier than
calling $.fn.progressPie.colorByPercent
.
- Source:
Methods
(static) draw()
progresspie
or progressring
not already containing an
svg
element and insertion of the pies into those elements, regarding further classes like color
for a red, yellow or green color (or something in between) dependent on the value (percent), red
or green
for constant colors and also taking into account the optional attributes data-percent
, data-piecolor
and
data-piecolor-function

Reds rumors indicate team looking to sign Zack Wheeler, big-name pitchers
by TSD StaffThe Cincinnati Reds are finally preparing to “go for it,” with their young guys having developed, and the trade with the Dodgers adding veteran talent to round out the roster.
It’s been a few years of rebuilding, but the team is now looking to build around the talent it has, while adding a few key pieces in free agency to shore up their weaknesses.
And it’s pretty easy to identify the team’s No. 1 weakness — starting pitching.
As such, the Reds are expected to sign at least one top-flight pitcher over the next few weeks, with Mets hurler Zack Wheeler near the top of their list, as he gets set to hit the free-agent market, according to Ken Rosenthal of The Athletic.
Rosenthal reported that the team is interested in Wheeler, which comes on the heels of the news about the team being in on Marcell Ozuna as well.
Wheeler had a rough 2019 campaign, posting a 11-8 record and 3.96 ERA for the Mets.


FAQ
Project background
What is the Coral Project?
The Coral Project is a collaborative effort to improve community on news sites through open-source software. You can read more about it on our website.
What do you do?
We’re creating open-source software to facilitate the importing, storage, moderation, and display of contributions to news websites. That includes images, video, and text such as comments, annotations, and blog posts.
Who’s behind the project?
It’s led by a team from Mozilla, The New York Times, and The Washington Post. It’s funded by a two-year grant by the John S. and James L. Knight Foundation. The ideas guiding it are coming from readers, contributors, journalists, community managers, researchers, and developers.
This is that comment system that Mozilla is building for the Times and the Post, right?
Not exactly. All three organizations are working together, and we’re focusing on many kinds of text contributions, as well as images and video. We’ll be creating software that publishers — or anyone, really — can use to better connect with their community. And that contributors can use to better connect with publishers.
What about digital community do you want to improve?
We want to give publishers the ability to better understand their contributors and control the level of discourse on their sites; empower contributors to manage their identities and data; and provide readers with a more productive discussion about current events.
Development process
So you’ll release your software in two years?
No, we’ll be creating software throughout our grant period and working with contributors, publishers, academics, and readers to iterate on it.
How long has the project been going?
We had a research phase in early 2014, our grant was approved in June 2014, and we’ve been planning and building our team in the time since.
How will the software work?
We’ll be building a flexible core system and a series of plugins, all connected through APIs. Publishers — or anyone, really — can choose to use everything we deploy or pick and choose plugins that fit specific needs.
Will it work on mobile?
We’re developing for all browsers and devices.
Is this for me?
I’m a regular commenter on news sites. What’s in it for me?
We want to give you tools to own and manage your identity and contributions across websites and analytics that allow you to understand who’s interacting with the content you create.
I work at a news site that’s smaller than The Post and The Times. Will this work for us?
Our aim is to make the software we create easy to manage for publishers large and small. If you’ve got specific needs you’d like to talk about, please [email link]get in touch with us[/email link].
How can I keep up with what you’re doing?
Watch this website. We’ll be posting updates regularly once our development begins in earnest.
I’ve got a few ideas to share with you. How can I get in touch?
Please get in touch with us here. We’re eager to hear from you.
Data sources
Which external data sources are supported?
We currently support mySQL, PostgreSQL, MondoDB, and REST APIs.
We use Elasticsearch. Can we connect to that?
Not yet. Our currently supported external data sources are mySQL, PostgreSQL, MongoDB, and REST APIs. However, you can write your own driver to connect to Elasticsearch. The drivers are part of the Sponge app, and you can find out more about the driver components here.
How often does the data refresh in the Trust app?
The data in the Trust app refreshes every 24 hours.
Installation
How would we get started?
You can learn more about the different installation options on our developer overview page. The quickest and easiest way to get started is probably the All-in-One Docker installation, but you can read about each available option (and whether it is likely to be the best option for you) on the developer overview page.
Do you have dummy data that we can use?
Yes. Our dummy data consists of real comments data, thoroughly scrubbed and anonymized.
If you install Coral through the All-in-One Docker installation, you should automatically have the dummy data set up for you in your MongoDB.
If you want to manually import sample data (for example, if you’ve installed Coral from source code), you can read more about how to do that on the developer setup page.

Elixir v1.3.4 Macro.Env
A struct that holds compile time environment information.
The current environment can be accessed at any time as
__ENV__
. Inside macros, the caller environment can be
accessed as __CALLER__
.
An instance of Macro.Env
must not be modified by hand. If you need to
create a custom environment to pass to Code.eval_quoted/3
, use the
following trick:
def make_custom_env do
import SomeModule, only: [some_function: 2]
alias A.B.C
__ENV__
end
You may then call make_custom_env()
to get a struct with the desired
imports and aliases included.
It contains the following fields:

Class PNP
- java.lang.Object
-
- algorithms.imageProcessing.transform.PNP
-
public class PNP extends java.lang.Object
iterative non-linear optimization using Levenberg-Marquardt algorithm to minimize the re-projection error of perspective projection in "perspective-n-point". L-M is guaranteed to converge to eventually find an improvement, because an update with a sufficiently small magnitude and a negative scalar product with the gradient is guaranteed to do so. TODO: consider implementing the Szeliski 2010 chapter 6 equations (6.44)-(6.47) NOTE: this implementation uses euler rotation angles and singularity safe updates, but future versions could consider using quaternions. This from Szeliski 2010: ..."Quaternions, on the other hand, are better if you want to keep track of a smoothly moving camera, since there are no discontinuities in the representation. It is also easier to interpolate between rotations and to chain rigid transformations (Murray, Li, and Sastry 1994; Bregler and Malik 1998). My usual preference is to use quaternions, but to update their estimates using an incremental rotation, as described in Section 6.2.2."- Author:

Apache Flink Kubernetes Operator 1.3.0 Release Announcement
December 14, 2022 - Matyas Orhidi (@matyasorhidi) Gyula Fora (@GyulaFora)The Flink community is happy to announce that the latest Flink Kubernetes Operator version went live today. Beyond the regular operator improvements and fixes the 1.3.0 version also integrates better with some popular infrastructure management tools like OLM and Argo CD. These improvements are clear indicators that the original intentions of the Flink community, namely to provide the de facto standard solution for managing Flink applications on Kubernetes is making steady progress to becoming a reality.
Release Highlights #
- Upgrade to Fabric8 6.x.x and JOSDK 4.x.x
- Restart unhealthy Flink clusters
- Contribute the Flink Kubernetes Operator to OperatorHub
- Publish flink-kubernetes-operator-api module separately
Upgrade to Fabric8 6.x.x and JOSDK 4.x.x #
Two important framework components were upgraded with the current operator release, the Fabric8 client to v6.2.0 and the JOSDK to v4.1.0. These upgrades among others contain important informer improvements that help lower or completely eliminate the occurrence of certain intermittent issues when the operator looses track of managed Custom Resources.
With the new JOSDK version, the operator now supports leader election and allows users to run standby operator replicas to reduce downtime due to operator failures. Read more about this in the docs.
Restart unhealthy Flink clusters #
Flink has its own restart strategies which are working fine in most of the cases, but there are certain circumstances when Flink can be stuck in restart loops often resulting in OutOfMemoryError: Metaspace
type of state which the job cannot recover from. If the root cause is just a temporary outage of some external system, for example, the Flink job could be resurrected by simply performing a full restart on the application.
This restart can now be triggered by the operator itself. The operator can watch the actual retry count of a Flink job and restart it when too many restarts occurred in a defined amount of time window, for example:
kubernetes.operator.job.health-check.enabled: false
kubernetes.operator.job.restart-check.duration-window: 2m
kubernetes.operator.job.restart-check.threshold: 64
Operator is checking the retry count of a job in every defined interval. If there is a count value where the actual job retry count is bigger than the threshold and the timestamp is inside the grace period then the operator initiates a full job restart.
Contribute the Flink Kubernetes Operator to OperatorHub #
The Apache Flink Kubernetes Operator has been contributed to OperatorHub.io by the Flink community. The OperatorHub.io aims to be a central location to find a wide array of operators that have been built by the community. An OLM bundle generator ensures that the resources required by OperatorHub.io are automatically derived from Helm charts.
Publish flink-kubernetes-operator-api module separately #
With the current operator release the Flink community introduces a more light-weight dependency model for interacting with the Flink Kubernetes Operator programmatically. We have refactored the existing operator modules, and introduced a new module, called flink-kubernetes-operator-api
that contains the generated CRD classes and a minimal set of dependencies only to make the operator client as slim as possible.
What’s Next? #
“One of the most challenging aspects of running an always-on streaming pipeline is the correct sizing of Flink deployments. … Clearly, it would be desirable to automatically adjust the resources for Flink deployments. This process is referred to as autoscaling.” - The Flink community is planning to propose an operator based vertex autoscaler. See FLIP-271 for further details. Beyond the autoscaler, which is one of the most anticipated features of the operator, the community is continuing to improve the stability, operability, and usability of the Apache Flink Kubernetes Operator on every front.
Release Resources #
The source artifacts and helm chart are available on the Downloads page of the Flink website. You can easily try out the new features shipped in the official 1.3.0 release by adding the Helm chart to your own local registry:
$ helm repo add flink-kubernetes-operator-1.3.0 https://archive.apache.org/dist/flink/flink-kubernetes-operator-1.3.0/
$ helm install flink-kubernetes-operator flink-kubernetes-operator-1.3.0/flink-kubernetes-operator --set webhook.create=false
You can also find official Kubernetes Operator Docker images of the new version on Dockerhub.
For more details, check the updated documentation and the release notes. We encourage you to download the release and share your feedback with the community through the Flink mailing lists or JIRA.

Anyways, thanks for the color scheme link!!! ---
Now that I no longer rely so much on my “work” laptop (a Dell Latitude D820), I’ve been a bit more open about rebuilding it and playing a bit with it.
A couple of weeks after coming home from the PDC in Los Angeles, I bit the bullet and repaved the machine with the Windows 7 Alpha we got. Installation went fine and everything seemed to work fine.
I was, however, not particularly impressed with it. Sure, there are a few nice UI and usability enhancements, but nothing that would make a really significant impact on my day-to-day usage. Performance was OK, but not great, either:
Neither of this is really surprising since it is still an early alpha and well, VPC isn’t great at supporting new OS releases anyway. However, it does tell me that we probably shouldn’t expect any major performance changes with Win7 over Vista (Heck, we’d be very lucky if performance remains the same with minor improvements here and there).
Last week I wiped Win7 and installed Ubuntu 8.10. This is the first time I’ve installed Ubuntu on this machine. I already hade Ibex running on my older Dell Inspiron 6000, where it works great and with very acceptable performance, and was curious how it would work out on the D820.
For the most part, it went well. Installation worked flawlessly, and all the hardware seems to work (though I haven’t exercised it too much yet). Performance-wise, it seems to behave very well, with good boot times and applications loading in very reasonable times.
The big difference between the two machines (aside from the D820 having a dual core processor) is that this one has an NVidia graphics card instead of the ATI on the Inspiron. I installed the NVidia proprietary drivers (version 177) and it almost works very well.
The reason I say this is that the driver works fairly well, with good video performance and so on. However, the Linux Achilles heel raises it’s ugly head again. Surprisingly enough, Suspend (sleep) seems to work fine and even pretty fast to get in/out of.
Hibernation, however, doesn’t work at all: The machine tries to get into hibernation and appears to almost succeed, but right away restarts as if had been rebooted instead. Haven’t yet dug in to see what exactly the problem is yet.
On the good news good front: On this clean installation I was able to get font rendering right away working correctly, and even succeeded in having the terminal application (gnome-terminal) render Envy Code R correctly!
