Introduction to programming
Conditions and loops
In this part of the course, we'll look at conditions and loops; as before, make a new copy of the template.html file and open it in your browser and text editor.
Conditional logic
Another very significant part of programming is conditional logic: performing different actions depending on user choices, differences in environment, etc. You might want to reveal whether an answer to a quiz question is correct or not, or do different things depending on different keys being pressed on the keyboard.
Conditional logic is usually done inside an if … else
structure (although there are other ways). Let's type in a simple example into the JavaScript area of our tempate file (also see my conditional example for a finished version):
var myTown = prompt("Enter your home town or city");
if(myTown === "Manchester") {
// At each stage here we are doing a test to see if
//the myTown variable is equal to a certain value
alert("Is it still raining in Manchester?");
// the code inside the curly braces is run if the
//associated test returns true
} else if(myTown === "Barcelona") {
// else if is how we chain another possibility on to the
// end of the block
alert("You have beautiful architecture, and sun");
} else {
// else is basically the last resort if none of the other
// tests return true
alert("I don't know your home town very well");
};
Each stage of this structure tests a condition, and depending on whether this condition is true
, you get a different result. If the condition is true
, the code inside the curly braces executes; if not it moves on to the next condition test.
Now try the following:
var myTown = prompt("Enter your home town or city");
if(myTown === "Manchester") {
alert("Is it still raining in Manchester?");
}
alert("I don't know your home town very well");
This still runs because the browser just keeps moving through the code sequentially. But there is a problem. What goes wrong here when you enter your myTown
variable value as Manchester
when prompted?
Exercise: Building onto our conditional code
In this exercise, try adding some further conditions onto our existing code, to make it able to respond in more different ways when different town options are entered. Remember that for the first condition you need to write if() {}
, for further conditions you need to write else if() {}
, and then for your final default condition you just need to write else {}
.
If you get stuck, check that:
- You have closed quoted sections with a second quote mark.
- You have included semi colons at the end of the "action" lines (e.g. alerts and prompts)
- You haven't confused a single equals sign with a triple equals sign. Single equals is the assignment operator, and you use that to make something equal to something else ("x now equals y!") Triple equals is the strict equality operator, which is used to check whether something is equal to something else ("is x equal to y?")
If you want to create a response based on a combination of different conditions, you have a couple of choices. First of all, you can use the OR and AND operators to make an if ... else
statement return true if or one or more conditions are true. For example, here's an OR operator being put to use (run the code if myTown
equals Manchester
OR Bradford
):
if(myTown === "Manchester" || myTown === "Bradford") {
alert("It is rainy in those Northern towns.");
}
And now an AND operator (run the code if myTown
equals Manchester
AND mySeason
equals Summer
):
if(myTown === "Manchester" && mySeason === "Summer") {
alert("Manchester must be enjoying some warmer weather.");
}
There is also nothing to stop you from nesting if ... else
structures. For example:
if(myTown === "Manchester") {
if(mySeason === "Summer") {
alert("Manchester must be enjoying some warmer weather.");
} else if(mySeason === "Winter") {
alert("Poor you! Must be really cold in Manchester
at the moment!");
} else {
alert("Is it raining in Manchester?");
}
};
Exercise: advanced conditionals
Now try using some AND and OR operators in your program, and/or a nested conditional.
Loops
Often you will want to do the same thing multiple times, perhaps changing the result a little bit each time. It is really tedious to write out loads of similar lines one after the other, so programming languages tend to provide loops to automate this for you. Let's say we wanted to make a number guessing game, where the program stores a number between 1 and 100 and then you have 20 guesses to get it right. Writing out the same code 20 times, once for each guess would be really tedious:
var theAnswer = 72;
// guess 1;
var guess = prompt("Enter a guess");
if(guess === theAnswer) {
...
}
// guess 2
...
// guess 3
etc.
A much better way to do this would be to use a for loop, the general structure of which looks like this:
for(i = 0; i <= 20 ; i++) {
// code in here can handle guesses 1 - 10, which become
// guess i in variable terms
}
Loops nearly always involve a single variable being iterated a certain number of times during the course of the loop. This can be called anything you like, but standard convention dictates that it be called i
, mainly due to laziness!
Inside the for()
brackets you have three values separated by semi-colons:
i = 0
— this is the starting value of the variable to be iterated.i <= 20
— this is the "exit condition" of the loop. So in this case, the loop will stop wheni
is no longer less than or equal to 10. When the value ofi
hits 11 the loop stops iterating, and the browser moves on to whatever comes next in the code. The loop needs an exit condition; if it didn't have one, the loop would never end, and the browser would just keep running the loop forever until it crashed. This is called an "infinite loop".i++
— this is the "iterator". Each time the loop has finished running, the iterator modifies the value ofi
in some way and then the loop is run again (unless of course that iteration is the last one, and the loop doesn't run again).i++
means "add 1 to i each time", and is shorthand fori = i + 1
.
Exercise: Implementing a basic loop
Soon we'll try to build the game described above ourselves, but first let's look at a simple real example that outputs the numbers 1 - 20 into the console pane.
for(i = 1; i <= 20 ; i++) {
console.log(i);
}
Try putting this into the JavaScript section of your template. Save and reload as before, then open the browser console pane so you can see the console.log
output.
This code is the equivalent of writing:
console.log(1);
console.log(2);
console.log(3);
console.log(4);
console.log(5);
console.log(6);
console.log(7);
console.log(8);
console.log(9);
console.log(10);
console.log(11);
console.log(12);
console.log(13);
console.log(14);
console.log(15);
console.log(16);
console.log(17);
console.log(18);
console.log(19);
console.log(20);
This reiterates how much more convenient loops can be for doing repetitive tasks!
Exercise: building a number guessing game
Ok, so the time has come for us to try working out how to build a simple game. Along the way I'll start introducing you to the idea of "thinking like a programmer." This is quite hard to come to terms to, but once you start to get it, you will find that the rest comes more easily.
Let's revisit my product description from earlier:
A number guessing game, where the program stores a number between 1 and 100 and then you have 10 guesses to get it right.
To start thinking like a programmer, you need to break this down into statements of what the program needs to do to succeed.
- Program needs to store a random number, 1-100.
- Program needs to give the user 10 guesses to get this right.
- The user needs to know whether they have got it right or not.
So how do we then take these and turn them into code? Let's go through them one by one.
Program needs to store a random number, 1-100.
This is how the program determines what the right answer is, in each game. This really ought to happen at the start of the game, before the guesses happen, so let's write this first. JavaScript has a built-in function that generates a random number between 0 and 1: Math.random()
.
- Wrap the following in a
console.log()
statement so we can see what it's doing. - We need to make it generate a number between 1 and 100. Let's multiply it by something to make the random number bigger.
- This gives us a random number between 0-99: the random number generated doesn't include 100. We need 1-100
- But this number is a decimal, plus it might give us slightly more than 100. We want whole numbers! Fortunately JavaScript has a built-in function called
Math.floor()
, which rounds its input down to the nearest whole number. How do we use this? - Let's refresh the browser with the console open to test it a few times.
- We need to store this in a variable, rather than output it to the console. Update the line like so:
console.log(Math.random());
console.log(Math.random() * 100);
console.log((Math.random() * 99) + 1);
console.log(Math.floor(Math.random() * 99) + 1);
var randomNumber = Math.floor(Math.random() * 99) + 1
Program needs to give the user 10 guesses to get this right
This sounds like a job for a for loop, right? What have we just been talking about?
- Let's add an empty for loop below our previous line of code
- Now we need to work out what the starting condition, exit condition and iterator are. We want to start at guess 1, stop providing guesses when the guess count reaches 10, and increase the guess count by 1 each time.
- So next, what do we need to do inside the loop? Well, we ought to think about how to let our user take a guess. What have we used in the past to allow the user the enter something?
for() {
}
for(i = 1; i <= 10 ; i++) {
}
for(i = 1; i <= 10 ; i++) {
var userGuess = prompt("Enter guess " + i);
}
The user needs to know whether they have got it right or not
- Now we should check whether the guess is correct. What structure can we use to do this?
- What condition do we put in here?
- Let's alert the user to tell them whether they got it right or not. How can we do this?
for(i = 1; i <= 10 ; i++) {
var userGuess = prompt("Enter guess " + i);
if() {
} else {
}
}
for(i = 1; i <= 10 ; i++) {
var userGuess = prompt("Enter guess " + i);
if(userGuess = randomNumber) {
} else {
}
}
for(i = 1; i <= 10 ; i++) {
var userGuess = prompt("Enter guess " + i);
if(userGuess === randomNumber) {
alert("Congratulations. You got it right!");
} else {
alert("wrong");
}
}
Advanced additions
First of all, the game would be a lot fairer if we could tell the user whether each guess is too high or too low.
for(i = 1; i <= 10 ; i++) {
var userGuess = prompt("Enter guess " + i);
if(userGuess === randomNumber) {
alert("Congratulations.
}
}
}
Also, the guesses should stop if the user guesses the correct number before the 10th guess.
for(i = 1; i <= 10 ; i++) {
var userGuess = prompt("Enter guess " + i);
if(userGuess === randomNumber) {
alert("Congratulations.
}
}
}

public static XMLCipher getInstance(java.lang.String transformation) throws XMLEncryptionException
XMLCipher
that implements the specified
transformation and operates on the specified context document.
If the default provider package supplies an implementation of the requested transformation, an instance of Cipher containing that implementation is returned. If the transformation is not available in the default provider package, other provider packages are searched.
NOTE1: The transformation name does not follow the same pattern as that oulined in the Java Cryptography Extension Reference Guide but rather that specified by the XML Encryption Syntax and Processing document. The rational behind this is to make it easier for a novice at writing Java Encryption software to use the library.
NOTE2: getInstance()
does not follow the

javax.crypto.Cipher

Report cites FAA failures in crash of Alaska floatplane
ANCHORAGE, Alaska (AP) - A new report says Federal Aviation Administration errors contributed to the crash of a floatplane in Alaska.
The Anchorage Daily News reported Thursday that the National Transportation Safety Board report criticizes FAA oversight of the company operating the July 2018 flight.
There were no deaths when the de Havilland Otter owned by Taquan Air crashed into Mount Bradley in Juneau.
Six passengers were seriously hurt and four sustained minor injuries on the flight originating at Prince of Wales Island.
The report says the FAA allowed Taquan to keep an operations director who was at times too busy to oversee flight safety due to another aviation job.
An FAA spokesman said Thursday that the agency could not immediately respond to questions about the report it had just received.

The Expanse's Season 4 Trailer Shows Us A Brave New World With Dangers At Every Turn
by Charles Pulliam-MooreThe Expanse’s fourth season drops on Amazon Prime in just a few weeks meaning that after months of being cryptic about what’s to become of the Roci crew on the strange, new Earth-like planet Ilus, the studio’s finally dropping the kinds of trailers that give you some solid information about what to expect. In this case, it’s one hell of a bumpy ride.
The Expanse’s latest trailer makes clear Ilus is anything but a paradise. Between the forces of both Mars and Earth looking to colonise the life-sustaining planet for their own means and the protomolecule’s crazy metal-spewing storms, Ilus might just be anything but a potential new hope for displaced Belters.
Settlers are managing daily life now, but the Roci crew arrives to signs Ilus just might be connected to the Protomolecule, and those aforementioned massive storms filled with Protomolecule technology that are constantly besieging the planet. As if all that’s not bad enough, there’s bound to be even more to Illus’ danger than the weather.
We also get a good look at Burn Gorman’s (Torchwood) new character, who seems to be a major cause of trouble himself, and a whole lot of other surprises.
The Expanse’s fourth season premieres Amazon Prime on December 13. Here’s a new poster Amazon just debuted as well.

Conclusion
In this suite, we have investigated Maxwell's equations in vacuum without time-varying fields.
Let us restate the equations in differential form.
$$ \nabla \cdot \mathbf{E} = \frac{\rho}{\epsilon_{0}}$$
$$ \nabla \cdot \mathbf{B} = 0$$
$$ \nabla \times \mathbf{E} = -\frac{d\mathbf{B}}{dt}$$
$$ \nabla \times \mathbf{B} = \mu_{0} \mathbf{J} + \mu_{0} \epsilon_{0}\frac{d\mathbf{E}}{dt}$$
Without time-varying fields, we have
$$ \nabla \cdot \mathbf{E} = \frac{\rho}{\epsilon_{0}}$$
$$ \nabla \cdot \mathbf{B} = 0$$
$$ \nabla \times \mathbf{E} = 0$$
$$ \nabla \times \mathbf{B} = \mu_{0} \mathbf{J}$$
In the upcoming suites, we will bring ourselves one step closer to applying Maxwell's equations in a real-world situation by asking:
How happens when we have time-varying fields?
How do we apply Maxwell's equations to different materials or medium? (add link to this)
Stay tuned!

Amistad A film review by Marty Mapes Copyright 1997 Marty Mapes
**1/2 (out of 4) Steven Spielberg is like Alfred Hitchcock.
A professor of mine once raised the question of whether Alfred Hitchcock was a genius or merely a carnival ride operator.
On the one hand, most of his films are exceptional pieces of work. Suspense, intellect, and morality weave through his films, giving them first-time enjoyment and multiple-viewing substance.
On the other hand, most of his movies are so easily analyzed, and were created with such calculated intent, that it's almost as if he never created anything original, other than the PROCESS by which he made movies. Once the process was in place, it only took a minimal effort to create a new movie each time.
Spielberg's AMISTAD has those qualities of Hitchcock's. On the one hand most of my observations were favorable; Spielberg and his long-time editor Michael Kahn packed many clever insights into the movie. On the other hand, many of these insights seem mathematically calculated. They are intellectual, and smooth, not evocative or mood-setting.
Because the story is so moving, a more emotional approach from a more intuitive (and less analytical) director would have worked better.
The movie opens on a close-up of the harshly lit, animalistic face of an African man wincing in pain and determination. This man is Cinque (pronounced "SING-kay," played by Djimon Hounsou) and he is extracting a spike from a post using only his fingernails and his willpower. He is able to free himself and others, and together, they take over the slave ship they are on, ironically named La Amistad (The Friendship, in Spanish).
None of the Africans know how to sail so they keep the ship's captain and a skeleton crew alive. They demand to be sailed back home. Instead of heading for Africa, the ship's captain sails to Boston where the Africans are recaptured.
Several interested parties claim ownership of the Africans. A black freeman and abolitionist, Joadson (Morgan Freeman), hires a young lawyer, Baldwin (Matthew McConaughey, showing his limited range), to file a claim for the captured Africans' freedom.
The trial goes rather quickly and favorably for the Africans, but just as it looks like the abolitionist's case will win, President Martin Van Buren (Nigel "King George" Hawthorne), up for re-election, appoints a new, less sympathetic judge to the case. The case is so airtight that the Africans are "freed," in spite of the new judge, but the case is appealed over and over, all the way to the Supreme Court. Along the way, Baldwin and Joadson convince John Quincy Adams (Anthony Hopkins, superb as always) to help them out.
AMISTAD is at its best when Cinque gets to tell his story. The scenes of his capture, enslavement, and sale are the most moving parts of the film. Sadly, they take very little screen time. Instead, a lot of time is spent in the courtroom or in the prison. These aspects of the story are interesting in their own right, but it's not where I would have focused my attention.
Spielberg placed the rhetorical fights of the courtroom over the emotional battles on-board. Like many of Hitchcock's stories, Spielberg's is calculated rather than evocative. Here are some examples from AMISTAD that reveal an insightful movie, more created than born:
• Still on the Amistad, at night and through the fog, the Africans first hear chamber music in the distance, then drift past another ship.  They are in the same place at the same time, yet their situations are so obviously different.
• The scene of the Africans' initial imprisonment ends with Cinque starting to cry.  From a man in pain and powerless to help himself, to a spoiled brat who will never know pain with more power than she knows how to handle.
• When it first appears that Baldwin and Joadson have won their case, a new judge is appointed and it appears likely that he will overturn their decision. Their world is turned upside-down. Literally. Spielberg shows us the new judge posing for a picture through a camera lens that inverts the image.
• One of the slaves is given a Bible. He can't understands the words, but he spends lots of time thinking about the pictures. He explains the story of Jesus to Cinque as best as he can by interpreting the pictures. They compare their own plight in America to the trials of Jesus. Right after they see the picture of the three crosses on Calvary hill, a ship sails by with three masts in the same configuration as the crosses, linking their martyrdom to his.
• Former supreme court justice Harry Blackmun, and not a professional actor, reads the final Supreme Court verdict. (He calls the ship the "Armistead.")
Each of these examples works very well, but they seem too perfect to be natural. In each example Spielberg adds depth by comparing and contrasting Cinque's situation with some other. But the examples don't arise from the characters or the story; they are clearly introduced by a godlike author. The effect is that you notice the author's winks rather than getting emotionally involved. And since the story of a slave revolt is such a rich mine for emotion, the direction of the film ends up working against the story.
I do think that Spielberg is a good director. He is very good at what he does. But his technique doesn't work for every story. His cold calculation doesn't work well with the hot injustice of slavery. AMISTAD would have been a better film from someone less thoughtful and more emotional, and Spielberg should stick to operating carnival rides.

Heavy snow hitting Hwy 3
by Colin DacreHeavy snow is falling on Highway 3 in Manning Park, with Environment Canada issuing a snowfall warning for the area Monday morning.
A total of 15 to 25 centimetres is expected to fall on the Allison Pass as several bands of moisture move over the area.
“Between these bands the snow will taper off. Periods of heavy snow are expected on and off through today and tonight,” the weather alert states.
As of 8 a.m., nine centimetres of snow had already fallen at Allison Pass.
“Prepare for quickly changing and deteriorating travel conditions,” Environment Canada says. “Rapidly accumulating snow could make travel difficult over some locations.


On May 13 1988 I was amused to read a report in The Daily Telegraph that the Royal Society for the Protection of Birds had erected a mesh fence to keep bird-fanciers away from a colony of little terns on Great Yarmouth beach, whose numbers had grown from 20 pairs to 70 pairs in three years.
On August 2 1990 I was interested to read a report in The Daily Telegraph as follows:
“Britain's biggest breeding colony of little terns, on Great Yarmouth Beach, Norfolk, where 201 pairs were nesting, has been largely wiped out by two hedgehogs and a kestrel.”
Kestrels, of course, are fanatically protected by all the high-tech and paramilitary resources of the multi-million pound RSPB, which on this occasion seems to have been hoist with its own petard, as they say. It is hard to know with whom we should sympathise most in this tale: the ordinary bird-fanciers, who were kept away from fancying little terns by a mesh fence put up by the superior bird-fanciers of the RSPB bureaucracy, or the unfortunate little terns, condemned to twitter away unseen.
My own sympathies are with the hedgehogs. They are delightful, if slightly flea-ridden, animals, with whom it is sometimes possible to hold an intelligent conversation. Has anybody ever had an intelligent conversation with a little tern? Hedgehogs do not demand a whole apparatus of repression to survive. Every time a hedgehog wipes out a little tern, it is a blow for freedom.
Auberon Waugh, “Nature Notes”, The Daily Telegraph, 11 August 1990

Compute the angular distance between two (spherical) points using Vincenty's spherical formula.
See Also: Functions vincentys, cosineAndoyerLambert_, cosineForsytheAndoyerLambert_, cosineLaw_, equirectangular_, euclidean_, flatLocal_/hubeny_, flatPolar_, haversine_ and thomas_. Note: Functions vincentys_, haversine_ and cosineLaw_ produce equivalent results, but vincentys_ is suitable for antipodal points and slightly more expensive (3 cos, 3 sin, 1 hypot, 1 atan2, 6 mul, 2 add) than haversine_ (2 cos, 2 sin, 2 sqrt, 1 atan2, 5 mul, 1 add) and cosineLaw_ (3 cos, 3 sin, 1 acos, 3 mul, 1 add). |

FontForge install procedures
for VMS =============================
- Installing from a pre-built vms package
- Installing on a unix/linux system
- Installing on a mac
- Installing on MS/Windows
- Building and installing from source
- Dependencies (external libraries/helper programs)
- Installing documentation
- Running FontForge
- Uninstalling
Installing from a VMS package
I'm afraid I have absolutely no idea what you need to do. All I can say is that Jacob Jansen has provided a vms package at:
He has provided the following notes:
Notes for VMS created on 17 November 2005
Compilation :
- -use MMS or MMK in the main directory (the one containing this file)
- -Ignore all messages about undefined symbols during linking of the shareable images. I have no idea how to supress them.
To use :
- the file [.libs]libfontforge.exe should be in a directory defined by the logical SYS$SHARE. So either copy it to it or redefine it i.e.: assign dev:[fontforge.fontforge.fontforge.libs],sys$sysroot:[syslib] sys$share
- To use the plugins (an example is in the [.plugins] directory) you have to create a logical FONTFORGE$PLUGINS pointing to all directories to be scanned for plugins i.e. define/job/trans=(concealed)/nolog fontforge$plugins dev:[fontforge.fontforge.fontforge.plugins.] Note that the final "." before the "]" is essential. Note that both logicals FONTFORGE$PLUGINS and SYS$SHARE can be defined system-wide, for a group of users or for a single user only.
