Waypoint Navigation
This sample demonstrates basic navigation using waypoints.Sample Overview
When programming the AI for your game, you often want your actors to follow a path that you supply. For example, you may want units in your RTS to follow orders, or perhaps you want to make a mouse navigate a maze.
This sample uses a tank to demonstrate two examples of this waypoint following behavior. In this sample, you can move the cursor around and add waypoints toward which the tank will move in the order that you add them.
| Note |
|---|
| This sample uses code and concepts from the Chase and Evade and Fuzzy Logic samples, and assumes that the reader is familiar with the code and concepts explained in those samples. |
Sample Controls
This sample uses the following keyboard and gamepad controls.
| Action | Keyboard Control | Gamepad Control | Windows Phone |
|---|---|---|---|
| Move the cursor. | UP ARROW, DOWN ARROW, LEFT ARROW, RIGHT ARROW | Left Thumbstick | Drag the cursor |
| Place a waypoint. | A | A | Release the cursor on the screen |
| Reset. | X | X | Touch the "Clear" button |
| Change the waypoint following behavior. | B | B | Touch the behavior button |
| Exit the game. | ESC or ALT+F4 | BACK | BACK |
How the Sample Works
The sample implements two types of behavior, LinearBehavior
and SteeringBehavior
, that determine how the tank moves from waypoint to waypoint.
LinearBehavior
LinearBehavior
causes the tank to move directly and abruptly to its waypoint. It does this by setting the tank's Tank.MoveSpeed to its Tank.MaxMoveSpeed and setting its Tank.Direction to be exactly towards its current waypoint at all times. This makes the tank change direction instantly and always move in a straight line towards the waypoint.
SteeringBehavior
SteeringBehavior
causes the tank to turn and to speed up or slow down smoothly as it moves toward the waypoint. It does this by using some geometry in SteeringBehavior.FindMaxMoveSpeed
to determine its target velocity. Then, to turn smoothly, it uses SteeringBehavior.TurnToFace
from the Chase and Evade sample.
Given an angular velocity w and a linear velocity v, the turning radius r of the tank is:
r = v/w
Anything inside a circle tangent to the tank's position on either side of it is inside the tank's turning radius and cannot be reached at its current velocity.
The solution is to estimate how fast the tank can move while still managing to reach its destination. We do this by finding the radius of the largest circle we can draw between the tank and its destination. Then, given this new radius, we use the following formula to determine a speed that guarantees that the tank can intercept its destination:
v = r * w
Extending the Sample
- Add obstacles and a second behavior that causes the tank to move around the obstacles as it moves from waypoint to waypoint.
-
Both tank behaviors have access to the list of waypoints, but both types of movement make use of the first remaining waypoint on the list. Create a new behavior that uses the built-in
Curve
class to fit all the waypoints onto a smooth curve that the tank can follow.


1
A questioner questioned concerning the doom about to fall
2
Upon the disbelievers, which none can repel,
3
From Allah, Lord of the Ascending Stairways
5
But be patient (O Muhammad) with a patience fair to see.
8
The day when the sky will become as molten copper,
9
And the hills become as flakes of wool,
10
And no familiar friend will ask a question of his friend
12
And his spouse and his brother
13
And his kin that harboured him
14
And all that are in the earth, if then it might deliver him.
15
But nay! for lo! it is the fire of hell
17
It calleth him who turned and fled (from truth),
18
And hoarded (wealth) and withheld it.
19
Lo! man was created anxious,
20
Fretful when evil befalleth him
21
And, when good befalleth him, grudging;
23
Who are constant at their worship
24
And in whose wealth there is a right acknowledged
25
For the beggar and the destitute;
26
And those who believe in the Day of Judgment,
27
And those who are fearful of their Lord's doom -
28
Lo! the doom of their Lord is that before which none can feel secure -
29
And those who preserve their chastity
31
But whoso seeketh more than that, those are they who are transgressors;
32
And those who keep their pledges and their covenant,
33
And those who stand by their testimony
34
And those who are attentive at their worship.
35
These will dwell in Gardens, honoured.
36
What aileth those who disbelieve, that they keep staring toward thee (O Muhammad), open-eyed,
37
On the right and on the left, in groups ?
38
Doth every man among them hope to enter the Garden of Delight ?
39
Nay, verily. Lo! We created them from what they know.
41
To replace them by (others) better than them. And we are not to be outrun.
42
So let them chat and play until they meet their Day which they are promised,
43
The day when they come forth from the graves in haste, as racing to a goal,
44
With eyes aghast, abasement stupefying them: Such is the Day which they are promised.

#include <stdio.h> void flockfile(FILE *filehandle);
int ftrylockfile(FILE *filehandle);
void funlockfile(FILE *filehandle);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
All functions shown above:
(Note: this locking has nothing to do with the file locking done by functions like flock(2) and lockf(3).)
All this is invisible to the C-programmer, but there may be two reasons to wish for more detailed control. On the one hand, maybe a series of I/O actions by one thread belongs together, and should not be interrupted by the I/O of some other thread. On the other hand, maybe the locking overhead should be avoided for greater efficiency.
To this end, a thread can explicitly lock the FILE object, then do its series of I/O actions, then unlock. This prevents other threads from coming in between. If the reason for doing this was to achieve greater efficiency, one does the I/O with the nonlocking versions of the stdio functions: with getc_unlocked(3) and putc_unlocked(3) instead of getc(3) and putc(3).
The flockfile() function waits for *filehandle to be no longer locked by a different thread, then makes the current thread owner of *filehandle, and increments the lockcount.
The funlockfile() function decrements the lock count.
The ftrylockfile() function is a nonblocking version of flockfile(). It does nothing in case some other thread owns *filehandle, and it obtains ownership and increments the lockcount otherwise.

Ruva is a fairly common type of unicorn that everyone seems to forget about These are some of the most classic unicorns--they come in mostly natural or pale, pastel-y colors, and live in meadows all across the world. They have a very special thing with flowers that no one really understands. They are commonly called "flower unicorns" because of it. They are the most similar unicorn to horses, by looks, and by having the faintest magical powers.
Price: $20M
One good kind of unicorn is the magi-corns. Magi corns live in abandoned fields left behind by farmers and human tribes. They eat the grass and crops. They have the one of the most powerful magic powers when it comes into pairs. They use all of there powers for good and stick together in pairs of two. They do this because if for some reason they needed to make a huge wave of energy and magic to protect themselves, they could put there horns together and create the biggest pulse of power in the world!
Price: $100M
There is one kind of unicorn that can fly, and it has wings and a horn. It is called a pegasus.  Their powers are to help all creatures. Whenever one of these unicorns is near you you will feel amazing! So if an animal of any kind is hurt or feels bad they will try to come by and help them to feel better. No one is exactly sure of where to find them, but they always seem to come save lives just when you need them!

Shortly after the return of Light Magic, the luminous dragons were discovered high in the Berrywhite Mountains. An apprentice of the wizard Mohs was researching a rare geological formation of rock chalk and happened upon an aerie of the majestic dragons.
Price: $50M
The chrome dragon is a vain dragon and has often been caught looking at its own reflection off of its shiny scales. Even though this dragon is extremely docile, it's probably best to approach it with caution. The sun's bright reflection has been known to start the occasional fire.

Marvel's Adversaries
Captain Marvel's arch enemy was the mad scientist Doctor Sivana, who regularly plotted elaborate schemes to rule the world and defeat both Captain Marvel and America. Sivana had four children who also had prominent roles in Captain Marvel's adventures. Two evil children, Georgia and Sivana, Jr., resembled their father both physically and in their desire to conquer the Earth. Sivana's daughter Beautia however, loved Captain Marvel and Sivana's son, Magnificus, was also a sometime-ally of the Captain.
Marvel's other adversaries included Captain Nazi and a nuclear-powered robot named Mister Atom. Matching Captain Marvel's adopted power from ancient heroes was Ibac, an evil magician who gained his power from the ancient villians Ivan the Terrible, Cesare Borgia, Attila the Hun, and Caligula.
One of the more popular serials in the Fawcett Comics run of Captain Marvel adventures was the Monster Society of Evil story arc which involved several of Marvel's adversaries from previous issues, including Doctor Sivana, Captain Nazi, and Ibac. The society was led by the cunning Mister Mind, a character who was eventually revealed to be a highly intelligent worm from another planet.

An IntSet is just a constant set, not a variable that you can post
constraints (like intersection) on. It's like the difference between
an IntVar and an int. If it's really about constants, you can use
range iterators to just compute the intersection.
If you want your sets to be real constraint variables, have a look at
one of the examples (like golf.cc), it will give you an idea how to
use finite set constraints in Gecode.

Province Tax : $ 0
Federal Tax : $ 0
Total Tax : $ 0
Owing : $ 0
The idea of creating a Personal Income Tax Calculator firstly comes from my own need to simply calculate and compare tax. There are a lot of tax tools online, but mostly focus on helping with tax form filling up, and so many of them are too complicated for non-professionals or showing different provinces tax rates in many different pages that makes comparision not friendly. Thus, I try to create a easy-use tax calculator with vasulized comparision by collecting official data from government website and developing an one-page website. I hope it's helpful and you will enjoy it.

Medium Clone
A core feature clone of Medium, a platform for readers and writers to come together
and enjoy high quality writing.
Readers are able to view lists of articles based on specific tags (such as cooking, JavaScript, politics, etc.) as well as like or bookmark
articles for later viewing.
Writers can use a customized text editor to draft, style, tag, and publish articles. Drafts are auto-saved, so writers can track progress and
reference previous drafts. When a reader likes or bookmarks an article, the author receives a notification informing them of who took what particular action.
I lead a team of four through crafting a business solution currently in use by three DevMountain campuses. The housing portal allows
administrators to manage student residents as well as associated properties.
Administrators can add students, create 'cohorts' (groups that students are organized into), manage other administrators,
as well as manage entire properties on different campuses.
A complex filtering system for students allows admins to selectively view any combination of students, as well as
make any necessary changes to student info.
Most importantly, admins are able to drag and drop students who need housing into open rooms, thus removing the need
to rely on Excel spreadsheets and to manage hundreds of students across nationwide campuses.

Roberto’s mistakes hand Burnley 3-0 win over West Ham
BURNLEY, England (AP) - Mistakes from West Ham goalkeeper Roberto handed Burnley a 3-0 win in the Premier League to end a losing run on Saturday.
Ashley Barnes scored in the 11th minute after Roberto failed to catch the ball at a corner.
Chris Wood put the ball in the net, only for video review to disallow it for offside, but scored soon after in the 44th after a poor pass in defense left West Ham exposed.
West Ham’s inconsistent stand-in for the injured Lukasz Fabianski, Roberto added an own-goal in the 54th, knocking the ball into his net at a corner.
After three straight losses, the win at Turf Moor returns Burnley to the top half of the table, while West Ham is on a seven-game run without a win in all competitions since beating Manchester United 2-0 on Sept. 22. The Hammers haven’t won away in the league since August.
There was another blow for West Ham in stoppage time as Manuel Lanzini was stretchered off with an apparent shoulder injury.

About me
My name is Christophre Benson, I'm 18, and I study Computer Science at Vanier College.
Hobbies
Music
My hobbies are listening to music mainly electronic
the genres I listen to are varied, but my favorites are the one's that are not that common such as :
- J-core: Japanese hardcore
- Eurobeat : european pop I think (It's known as drift music because of Initial D)
- Complextro : complex electronic music
- Funkot : dance music from Jakarta, Indonesia
- Full Flavor
- Touhou : from the 東方Project
- Speedcore : the fastest genre of electronic music, to be speedcore, the BPM must be atleast 300, sometimes the song's BPM goes in the thousands in that case its called Extratone. (Extratone : a subgenre of speedcore)
But some My favorite artists are :
Sports
I like sports, I've preacticed multiple such as :
- Archery, because we had archery in secondary during gym class and I realized that I had a natural talent in it, so I continued by taling courses until last year.
- Swimming, because I liked the water
- Soccer, because I liked running arround and the sport seemed interesting
- Spear Throwing, this is a sport that the school (Saint-Maxime) did near the end of the school year that I really enjoyed.
Video Games
another hobby of mine is playing video games and my favorite genres are:
- Bullet Hell : survive as long as you can while enemies spray bullets from pretty much every angle, as annoying as dying over and over to the same level, the feeling I get finally memorizing the bosse's patterns and betting them is very satisfiying.
- Stealth : sneak around, I like to feel
- Strategy : strategise to win. this one I like because I don't just press the same button to win and it involves a lot of thinking outside the box.
- Survival : survive as long as possible in various situations
- Horror : I like the suspense, not knowing what lies around the corner. But I also like psychological horror, because they mess with you and scare you without the need of jumpscares.
- Meta: games that are self aware, I like this one because its amazing seeing how much can be done with a program, I like seeing files get created/deleted/modified affecting the story and the game as I play. Or when the character is aware that they aren't real and talk to you (the player) and not your avatar.
- rhythm: mach the key at the right time following the beat of a song, I like this genre because I like to see how good I am at coordinating my eye, ears and hands.
Some of the games I like to play are:
- 東方 project : a japanese shmup/danmaku doujinshi(because the searies is made by one guy named zun) game, featuring characters from eastern mythology, urban legends and stories, such as the lengend of the bamboo cutter, the girl from the gap, Chang'e, unfortunately since the game is aimed at a japanese demographic it is not well known here in the west. But I really like the music as I mentioned earlier, I also like the characters and the story. The games offer a great challenge especially in Lunatic mode.

- Garry's mod(Gmod) : A sandbox game, an old game but still very fun to play with friends
- TF2 (team fortess 2) : A FPS red vs blue game where you get to play as a mercenary, there are multiple gamemodes. another old one but the game is still as active if not more than ever, there's even a story.
- Subnautica : its a horror, suvival game where you get stranded on an alien planet, mostly covered in water and you must survive and try to find a way to escape the planet, I really really like this game because the aquatic creatures in the game vary from cute to disturbing to very terrifiying, and the vibe you get from swimming around knowing you are alone on an alien planet not knowing what creature to expect is thrilling and scary.
- Minecraft : a creative sanbox game.
Reading
I also read on my free time, I like to read :
- SCP articles: an article created by talent storywriters, scp means secure, contain, protect, they are an organization dedicated to secure contain and protect anamolies, keeping them secret from the world, each entry focuses on individual scps, what if senarios or stories. The scp universe is heavily inspired by the lovecraftian creatures.
- 東方 project manga : as they hold additional stories following the charaters
- manga : they're like commic books but japanese and you read them backwards, I like them, they have good stories
Drawing
watching
I like watching anime and some of my favorite genres are:
- Slice of life : as they are very calming, they have nice visual lanscapes and wholesome stories
- action : as they have good music, suspense, animation
- fantasy : as its amazing to see how we can create entire worlds with our imagination
- Isekai: meaning another world, its fun to see someone come from another world and interract with people who live complete different lives from him
- dark fantasy: I also like it when they take fantasy but push it in ways you wouldn't think was normal
Studies
Languages
I like to learn new languages as they hep me pass the time and talking to people from other places is fun
Spanish
I had classes in my last year of high school, then I had additional classes next summer at YMCA
Russian
self thaught until beginner level but then stopped practicing for a while
Japanese
self thought but I'm still a beginner
korean
Just like the others I'm self thaught

Brooklyn Nets fans aim 'LeBron' chant at New Orleans Pelicans' Brandon Ingram
by Ryan GaydosBrooklyn Nets fans attempted to rattle New Orleans Pelicans forward Brandon Ingram on Monday night during their matchup with chants about his former teammate.
During the matchup, fans were reportedly yelling “LeBron didn’t want you” while Ingram was shooting free throws. Ingram played with LeBron James last season before the Los Angeles Lakers traded him to the Pelicans in part of a package to land Anthony Davis.
According to The Athletic, Ingram hit both free throws and then followed up with a finger-roll layup. To make things more interesting, Ingram finished the game with a career-high 40 points on 17-of-24 shooting.
HOUSTON ROCKETS FAN ACCUSED OF PUNCHING NEW ORLEANS PELICANS COACH BANNED FROM NBA EVENTS: REPORT
He added five rebounds, five assists, and two steals as well.
However, it was Brooklyn who would get the last laugh in the game.
The Nets got 39 points from Kyrie Irving and 23 points from Caris Levert to secure the 135-125 win over New Orleans. Taurean Prince added 12 points and 11 rebounds while Jarrett Allen had 18 points and 10 rebounds.
The Pelicans fell to 1-6 on the season and are currently in last place in the Southwest Division. The team plays again Friday against the Toronto Raptors at home then follow up with a road game Saturday against the Charlotte Hornets.

The False Beauty of Sin
By A.C.
From a very young age, the image of Satan that we are presented with is almost always the same. It’s some dark character dressed in red with horns and a pitch fork. And as we grow older, this image, although not as juvenile, remains the same. He is always presented on TV and motion pictures as some evil dark character that seems somewhat out of place. His evil presence, according to many of these films, can be detected immediately without hesitation. A certain look, or an eerie voice allows the viewer to visually understand that this character is different in some way than the rest. The intention is to make him unique. He has to be, he’s evil, he the Devil…
But what does the Bible say about this pitch forked enemy we know as Lucifer or the Devil? What are his true characteristics and how does the Bible warn us about his ultimate goal in the believer’s life?
The book of Ezekiel gives us the first glimpse into our adversary, seemingly from the moment before time as we know it, began. Chapter 28 verse 12 says this, “You were the model of perfection, full of wisdom and PERFECT IN BEAUTY. You were in Eden, the garden of God, every precious stone adorned you.” According to these not-so-easy to understand verses, God created Satan and he was physically beautiful. That was not an easy sentence to write, but if it’s in God’s word we can’t just dismiss what He may be trying to tell us. The remaining verses in Ezekiel, although tough to totally comprehend, says that because of his beauty, he rebelled against Almighty God.
Just as important as his physical attributes given to us in scripture, is how he tries to work against us. Does he use the core of his beauty in any way to tempt and deceive us? Are his attacks always in a dark negative tone or can it be more deviously clever than we think? Does he always come against us with things that are unpleasing to our human mind and hearts or does he appeal to the fallen nature known as “our flesh”?
Whatever methods he uses, his ultimate goal is to entice us away from our secured salvation from sin. Now I know there are many people who may say that once we become a Christian our salvation is eternally sealed. In some way I would agree, but what do we do with verses like this, “See to it brothers and sisters that none of you have a sinful unbelieving heart that turns away from the living God”? (Hebrews 3:12 NIV) If the Bible states that sin has the power to turn our hearts away from the only true God, then we need to know more on how it operates.
First we must realize that Satan does have full on frontal assaults when we are Christians. There’s no hiding this fact. Ask our brothers and sisters in Syria who are being beheaded for the faith that they refuse to deny even at the cost of their very lives. But what other methods does he use? Can his attacks come in a more subtle, appealing way? Many years ago I read this scripture in Proverbs that has remained ingrained in my memory. It talks about the deceitfulness of sin. “Do not gaze at wine when it is red, it sparkles in the cup, when it goes down smoothly. In the end it bites like a snake and poisons like a viper.” (Proverbs 23:31) Simply put, sin in its original state is fun, enjoyable, and appealing to the human eye, but in the end, ultimately, it brings death.
Sadly, many Christians have lost their way not because they were hit with a barrage of frontal attacks by the enemy but because they were enticed away by the false beauty of sin. From something that may have started out so innocent and simple, ended in embarrassment, heartache or even spiritual death. How many of us have been tempted in this way by the pull of the “beauty” of sin? It may not be as uncommon as you think. Do you think that the alcoholic started out locking himself in a room drinking a bottle of alcohol a night? No, it starts out many times with just a small glass during a party in order not feel out of place. And like most sin, once it hooks you in, it’s not so easy to get free from.
To my own shame I have succumb to pressures like this. You get with old friends and it’s a casual toast to remember “the good old days.” All sin needs is an open door. How many pastors have lost their ministries because of some “harmless” flirtation with the opposite sex? Harmless flirtations to full blown scandals. That is the damage sin can bring. Honest men and women who have had the very calling of God on their lives ruined through the “beauty” of sin. The Devil will stop at nothing to see our demise. Many Christians have married or gone into business with a non-believer even though scripture clearly warns against it. The excuses as to why it was done seem logical and innocent. I’m lonely or it’s a good way to supply for my family. It always has its start as the sparkling glass, and many times it ends with the bite of a viper.
Remarkably, no one is exempt from the beauty of these temptations. Satan even uses our own arrogance and pride to make us think “this could never happen to me.” The environment you live in or years served as a Christian doesn’t eliminate anyone from being a candidate to the physical lure and attractiveness of sin. In 1 Corinthians, Paul writes, “I strike a blow to my body (discipline my body) and make it my slave, so that after I have preached to others, I myself may not be disqualified for the prize.” (1 Corinthians 9:27 NIV) How can a man who wrote more than half of the New Testament and is a model Believer throughout Christian history be disqualified? Paul knew the draw and pull the “beauty” of sin possess.
If sin has this kind of deceptive draw and is originated through the evil powers of Satan, how do we as mere humans stand a chance?
Was it God’s design for us to fight these temptations off on our own? Did He ask us to pull it together and do our best? Never… In the small book of Jude comes one of the most powerful verses regarding sin in the entire New Testament. It’s our only answer to standing up against the beauty of the Devil’s schemes. It reads like this, “Now all glory to God, who is able to keep you from falling away and will bring you with great joy into His presence without a single fault.” (Jude 1:24 NLT)
The only way to resist the Devil’s lure of sin in your life: rest solely on the power of God working in you. God never intended to leave us defenseless against the attacks of the Devil no matter how appealing to the eye they may seem. Another translation has it, “To Him who is able to keep you from falling.” The power to overcome these temptations was given to us when God gave us His Holy Spirit. The more we give up the old desires we once had, the more the power of God himself fights on our behalf.
Paul says in the book of Galatians, “I have been crucified with Christ and I no longer live (for my own sinful desires) but Christ lives in me.” (Galatians 2:20 NIV) Think about what this verse tells us. Christ lives in me… The power of the God who created the universe is fighting sin on my behalf. And through the power that He gives, we can see the end result of the enticing circumstance before we engage in it. God gives us warning signals far in advance before it’s too late. He allows us to see the poison through the sparkle…
Do you feel like I once did, that sin has you wrapped too tight in its clutches that you can’t break free?  If you’ve never experienced the life changing power of God that fights off sin, it’s never too late to call on Him for help. His word says, “If we confess our sins, He is faithful and just to forgive us our sins and cleanse us from all unrighteousness.” (1 John 1:9 ESV)
He’s waiting to set you free……
Just Something to Consider.

Native types are implemented by operating system. We name native types using a single lowercase letter followed by number of bytes. The maximum range is a power of 2 multiplied with the number of bytes specified.
| Type Name | Name | Min | Maxim |
|---|---|---|---|
| i | Signed | 8 | 64 |
| u | Unsigned | 8 | 64 | f | Float | 32 | 64 |
Native types are not usually necesary in Eve scripts. However the system library is using these types to create Primitive Types. A native type can be boked using a primitive type as a box.
Primitive types are predefined in Eve core library. They have an equivalent native type. Primitive types are slower than equivalent native types, but have more features.
| Class Name | Description | Minim | Maxim |
|---|---|---|---|
| Byte | Is a Numeric type having range: (0x00..0xFF) | 0 | 2^8-1 |
| Short | Is a Numeric type having range: (0x0000..0xFFFF) | -2^15 | +2^15-1 |
| Integer | Signed on 64 bit | -2^63 | 2^63-1 |
| Natural | Unsigned on 64 bit | 0 | 2^64-1 | Double | Float precision number on 8 bytes | -n | 1.8 × 10^308 |
| Symbol | Single symbol UTF-8 encoded, 4 bytes | 0 | 2^32-1 |
| Ordinal | Enumeration of symbols, Equivalent to Short | 0 | 2^16-1 |
| Date | Calendar date | 01/01/0001 | 01/01/9999 |
| Time | Time of the day (24h) | 0 | 8.64e+7ms |
| Duration | Period of time | 0 | 2^16 |
| Logic | Is a Ordinal subtype having values: False = 0, True = 1 | 0 | 1 |
In Eve we can have two categories of numbers:
| Category | Eve Types |
|---|---|
| Discrete | Byte, Short, Integer, Natural, Ordinal, Range, Symbol, Duration |
| Continuous | Float, Double, Rational, Complex |
Discrete numbers have a range from negative to positive number that can be calculate easly by the number of bytes. We have equivalent native numbers for every number of bytes from 1 to 64.
| type | Chars | Equivalent | min | max | maximum number |
|---|---|---|---|---|---|
| Integer | 20 | i64 | -2^63 | 2^63-1 | ≤ 9,223,372,036,854,775,807 |
| Natural | 20 | u64 | 0 | 2⁶⁴-1 | ≤ 18,446,744,073,709,551,615 |
For conversion into characters:
The type Double is represented using floating precision numbers.
Floating decimal numbers are most simply described by 3 Integers:
The numerical value of a finite number is −1ˢ × c × 2ⁿ Using this formula Eve define two floating point types.
Single: is single-precision 32-bit IEEE 754:
Double is double-precision 64-bit IEEE 754:
| type | Digits | Equivalent | maximum number |
|---|---|---|---|
| Float | 7 | f32 | ≤ 3.4 × 10^38 |
| Double | 16 | f64 | ≤ 1.8 × 10^308 |
| Rational | 20 | q64 | ≤ 2^64(*) |
Note Precision and range for Rational numbers is variable depending on the resolution. Ratiobal numbers are are using fixed precision arithmetics. When precision is 1, Rational numbers are equivalent to int64 that is a very large number using 20 digits.
| Example | Description |
|---|---|
| 0 | Integer zero |
| 123 | Integer number using symbols: {0,1,2,3,4,5,6,7,8,9} |
| 1/2 | Single number use symbols: {.,0,1,2,3,4,5,6,7,8,9} |
| 0.5 | Double number use symbols: {.,0,1,2,3,4,5,6,7,8,9} |
#numeric literals demo
driver numeric_literals:
** define global states
set g1 = 0.0 :Double;
set g2 = 0.0 :Float;
** define main process
process
** check equality
expect g1 == g2; -- value is equivalent
expect g1 is not g2; -- not the same
expect g1 not eq g2; -- different types
** define local variables

let n :=<PHONE_NUMBER>3709551615; -- maximum
let r := 1/2; -- 0.5
return;
See also: scientific notation
For representing a single character/symbol you can use single quoted strings. Single quoted strings can store a single UTF8 code point but it has a fixed size of 4 bytes. This type is called "rune" in Go language.
process
new letter := 'a';
new capital := 'B';
new number := '5';
new unicode := 'β';
new operator := '¬';
...
return;
Unicode literals start with prefix U+ or U-. Such literals is compatible with single quoted Symbol code point. Unicode literals are case insensitive hexadecimals.
Composite data types are unions of data elements. A composite variable that is not initialized can have Null value. These types are going to be explained later in other pages.
Note: We try the best to enable implicit data types for specific literals. For most cases, impicit data type works. Sometimes you need precise to specify the type using a type hint.
| Class Name | Description |
|---|---|
| Object | Root class for all composite data types |
| Record | Flat collection of native data types. (No objects) |
| Variant | A union of possible data types. |
| Range | Discrete range of numbers equaly distanced (x..y:ratio) |
| Pair | A pair is like a list but it has only two elements (k:v) |
| String | Double quote delimited symbol: "..." |
| List | Dynamic ordered enumeration of values of same type |
| HashMap | Enumeration of (key:value) pairs unique sorted by key |
| DataSet | Enumeration of unique elements of the same type |
| Table | A collection of records indexed by unique key. |
| Function | Function object type/ reference to function. |
| Vector | Single-dimensional, fixed size array |
| Matrix | Multi-dimensiona, fixed size array |
| Error | Composite type derived from Object base class |
A range is a notation that can create a class or a collection of discrete elements. Range is not expanded in memory until is assigned to a variable.
Ranges can be used as generators to populate collections, make logic evaluations, or generate values for loops. Range operations should be optimized by the compiler using leasy evaluation. Elements are generated as needed not stored in memory.
new l := (min..max:ratio); // list new a := [min..max:ratio]; // array new d := {min..max:ratio}; // data set
Numeric ranges:
#numeric range demo
driver numeric_range:
** define a validation class
class R5 = (0..5) <: Range;
process
** test range limits
expect 0 in R5;
expect 5 in R5;
** test limits with other ranges
expect 4 in (1..8:2)
expect 5 not in (-10..10:2)
return;
Symbol range, specify Unicode symbols as limits.
# using symbol ranges
driver symbol_range:
process
** elements of these ranges are written one by one
print ('0'..'5') -- ('0','1','2','3','4','5')
print ['a'..'f'} -- ['a','b','c','d','e','f']
print {'A'..'F'} -- {'A','B','C','D','E','F'}
** use range as validation domains
expect '0' in ('0'..'9'); -- range of digits
expect 'c' in ['a'..'z']; -- range of symbols
expect 'X' in {'A'..'Z'}; -- range of symbols
return;
It is possible to create a decimal range. For this, the limits must be decimal or at least the ratio must be decimaL. If ratio is not specified, it is automaticly created: 0.1 or 0.01 depending on precision of first limit. 0.0 or 0.00. In Eve the number of zeros can establish the precision for numeric ranges.
# using fractional ranges
driver fraction_range:
process
** elements of these ranges are written one by one
print (0..0.5:0.1) -- (0.0,0.1,0.2,0.3,0.4,0.5)
** use range as validation domain
expect 0.01 in (0.0..1.0);
expect 0.001 in (0.00..1.00);
expect 0.001 not in (0.0..1.0);
return;
In computer science coercion is used to implicitly or explicitly change an entity of one data type into another of different type. This is ready to take advantage of type hierarchies and type representations. If not designed properly the coercion can be a fatal mistake. Eve is a safe language so we do only safe coercion.
Implicit coercion In Eve the arithmetic operators are polymorphic. Numeric operators can do implicit data conversion to accommodate the data types and return an accurate result. Automatic conversion is possible only when there is no risk of loosing data precision. If there is a loss of precision we can end-up with a run-time error. To prevent this Eve will implement a safe compile-time check.
#example of implicit conversion
driver implicit_coercion:
process
** local variables
new a := 2;
new b := 1.5;
** alter a, b
let b := a; -- this implicit cast is possible b = 2.0
let b := a + 3.5; -- add 3.5 then assign result to b = 5.5
let a := b; -- error: can not assign Double to Integer
let a := 1.5; -- error: can not assign Double to Integer
return;
Explicit coercion Explicit coercion is a forced conversion. Can be used to convert backwards from higher data range to lower data range or from continuous numbers to discrete numbers. This however can cause a data or precision loss. Explicit coercion is using a function.
Examples of explicit coercion:
# explicit coercion in EVE
driver explicit_coercion:
set a = 0 :Integer;
set b = 1.5 :Double;
process
**explicit coercion lose (0.5)
let a := floor(b);
write a; -- will print: 1
**explicit coercion add (0.5)
let a := ceiling(b);
print a; -- will print: 2
**explicit coercion rounding:
let a := round(b);
print a; -- will print: 2
return;
Number to a string
#convert number to string
driver number_to_string:
** local states
set s :String;
set v :Integer;
process
let v := 1000;
let s := format(v); -- explicit coercion s = '1000'
expect (s == '1000');
return;
String to a number
This can be ready using the casting function parse(), only if the string contains a number. Otherwise the conversion fail and will rise and exception.
#string to number conversion
driver string_to_number:
** global states
set v :Integer ;
set b :Double ;
set s = "1000" :String;
set r = "200.02":String;
process
let v := parse(s); -- make v = 1000
let v := parse(r); -- make v = 200 and decimal .02 is lost
let b := parse(r); -- make b = 200.02 and decimal .02 is preserved
return;
Note: Build-in functions that are located in EVE default library: { parse(), format(), ceiling(), floor() round()}. This module is one of the standard modules that are automatically included in any Eve program.
Literals are representations of specific particular data type in source code.
Basic types Next notation use "9" to show any digit in range (0..9).
| Literal | Type |
|---|---|
| 9 | Integer |
| -9 | Integer |
| 0x9ABCDEF | Natural |
| 0b1010101 | Binary |
| 9.9 | Double |
| U+0001 | Word |
| U-FFFFFFFF | Binary |
Zero literals
| Literal | Type |
|---|---|
| [] | Vector |
| {} | Object/DataSet/Table |
| () | List/Range/Pairs |
| "" | Text |
| '' | String |
| 0 | Integer |
| 0.0 | Double |
Collection literals
| Literal | Type |
|---|---|
| (1, 2, 3) | List[Integer] |
| ("1","2","3") | List[String] |
| {a:0, b, c} | Ordinal |
| {a:"x",y:2} | Object |
| {3, 4, 6} | DataSet[Integer] |
| [1, 2, 3] | Vector[Byte](3) |
| ['a','b','c'] | Vector[Symbol](3) |
| ["a","b","c"] | Vector[String](3) |
| [[1,2],[2,4]] | Matrix[Integer](2,2) |
Type inference is a logical association of data type from a constant literal or expression. Type inference can be used in declarations.
Type inference is enabled by operators {:=, ::}. You can use type inference with keyword "new" or "let". Type inference can improve a type declaration if the declaration is partial.
In next example we use a List data literal to create a shared collection fo type List[Integer]. However the type used is partial. Do not have element type, that is going to be Integer.
#test partial inference
driver type_inference:
** Define a list without element type
set ls :List;
process main
** establish element data type
let ls := (0,1,2,3,4,5,6,7,8,9);
print ls.type();
expect type(ls) is ()Integer;
return;
You can declare empty collections using partial inference and determine the type of elements later, using "let". After type is established, it can't be changed later and start functioning as a contract. That is, you must respect the element types for next expressions.
# gradual type declaration
process
new a := (); -- empty List
new v := []; -- empty Vector
new s := {}; -- empty DataSet
** add elements
let a := (10,11,12) -- establish element type
let a += "4" -- error, elements are Integer
return;
We can verify the type using "is" operator:
# using operator "is" to check type
driver type_check:
** define object and initialize
set r = {name:"test", age:24} :Object;
** define hash table
set t = {'key1':"value1",'ley2':"value2"} :DataSet;
process
** check variable types using introspection
expect type(r.name) is String;
expect type(r.age) is Integer
expect type(t.key) is Symbol;
expect type(t.value) is String;
return;
For type introspection we can use type() built-in function:
# introspection demo
process print_type:
new i := 1.5;
expect type(i) is Double;
print "type of i is \s" ? i.type();
return;
In mathematics there are very few operators: {+, -, ÷ , * } that can operate with any kind of numbers: negative, positive, rational or real. Operators are not bound to specific data types. Therefore these operators are called "polymorphic".
Some languages define different operators for Integers and Floating decimal numbers. For example in OCaml the operator "/" can divide Integers while "/." can divide Floating point decimal numbers. This is unexpected for a mathematician who is expecting to use one single operator for division.
In EVE, operators are mapped to functions. To design polymorphic operators we overload the function signature using type dispatch. The dispatch is using left side operand first, this is the leading operand. For unary operators there is only right side operand so this becomes the leading operand.
In Latin the "falsus" and "verum" are translated in English to "false" and "true". In many languages False and True are two constants. In Fortran we use to have .T. and .F. condtants while in C we use to have {0, 1}. Two values.
| name | value | binary |
|---|---|---|
| False | Logic.False | 00000000 00000000 |
| True | Logic.True | 00000000 00000001 |
** explicit initialization
global
set False = 0b0 :Byte;
set True = Ob1 :Byte;
Internal design
Probably best to define Logic type is Ordinal:
class Logic = {False:0 , True} <: Ordinal;
Logical expressions
A logical expression is a demonstration or logical deduction having result True or False. Operator precedence is: {not, and, or, xor}. The order of operations can be controlled using operator precedence and round parentheses.
Result of logical expressions can be used into a conditional statement to make a decision. Also results of logical expressions can be stored in logical variables to be used later in other conditions.
In Eve you can define new data types. Types are derived from system types. When you create a new type you can use { }, [ ] or ( ) to define the type structure.
User types are defined in a region that start with keyword "type". You can define multiple types on several lines separated by semicolumn and end of line.
Gradual typing is a type system in which some variables may be given a type. Some variables or members may be left un-typed. Therefore some type errors are reported at compile-time some other at run-time.
Gradual typing is different than type inference. On type inference the type specification is missing but default type is determined by logic deduction from literals and expressions.
A Variant is a polymorphic variable that can have one of a list of types but only one at a time. When the value is established, one type to hold that value is created.
** define variant subtype
class VNamme = {Type1 | Type2 | ... } <: Variant;
** declare variable (with initial value)
global
set v = value :VNamme;
For this we use a special type Null
** define nullable variant
driver test_nulable:
class Number = { Integer | Double | Null } <: Variant;
** use nullable variant
global
set x: Number;
process
let x = 10; -- x is Integer
let x = 45.5; -- x is Double
let x = Null; -- x is Null
expect x is Null;
return;
A variant can establish its data type at runtime:
In next example we use a variant that can be Double or Integer.
#variant type demo
driver variant_type:
** tefine variants
set v, x ,t: { Double | Integer };
process
** safe conversion
let t := 1 / 2; -- make t Double
print type(t) -- Double
let t := 12; -- change type
print type(t) -- Integer
** unsafe conversion
let x := 1.5; -- x is Double
let v := 1; -- v is Integer
let v := x; -- v becomes Double
print type(v) -- Double
return;
A variant is a way to create a generic routine. For this we use variant parameters:
# variant parameter in routines
driver variant_params:
** define a subroutine that can swap two numbers
** requires input/output parameters marked with @
routine swap(@x, @y: {Integer | Double} ):
** check type to be the same
expect type(x) = type(y);
** swap x, y values
new i := x; -- intermediate
let x := y; -- first swap
let y := i; -- second swap
return;
process
** invert two Integer numbers
new x := 10;
new y := 20;
call swap(x, y);
expect (x == 20) and (y == 10);
** invert two Double numbers
new a := 1.5;
new b := 2.5;
call swap(a, b);
expect (a == 2.5) and (b == 1.5);
return;
In Eve we represent calendar date.
Date storage
Date literals
When can create a date literal using 3 format functions:
Note: A reversible function is overloaded.
#overloaded function
process
new date := "2019/01/30" as YDM;
** convert string in Date type
print date as YDM; -- 2019/01/30
print date as DMY; -- 30/01/2019
print date as MDY; -- 01/30/2019
return;
For time you can use Time or Duration data types.
Time format is created from string literals using two reversible functions: t12() and t24(). These functions are using constants T12 and T24 that represent standard time format.
ss: can be 0..60 seconds
xx: can be: (am/pm)
# time demo
driver time_demo:
process
** define 3 variable of same type
new time1, time2, time3: Time;
** alter variables using "as" operator
let time1 := "00:23:63" as T24;
let time2 := "23:63:59,999" as T24;
let time3 := "11:63:59pm,10" as T12;
** check time
expect time1.h == 23;
expect time1.m == 63;
expect time1.s == 59;
expect time3.ms == 10;
expect time3.t == pm;
return;
Duration is represented as a number on 32 bits. Internally is stored as milissecond. It can hold almost 20 days. For longer duration, you must use Time object.
# duration demo
driver duration_demo:
process
** define 3 variable of same type
new d1 := 10ms; -- 10 millisec
new d2 := 1s; -- 1000 millisec
new d3 := 1m; -- 60000 millisec
** create duration from string
new d4 := Duration("01:01:01");
** check time
print d3 -- 60000ms
print d4 -- 3661000ms
return;

Introduction to R The R Bootcamp |
adapted from static.memrise.com
In this case study, you will analyse historic data of three major stock indices, the Dow Jones, the DAX, and the Nikkei, and the exchange rates between the US dollar, the Euro, and the Yen. Using this data, you will address several questions.
To address these questions, you will import several data files, using various function parameters to match the idiosyncrasies of the data. You will merge the data files into a single data frame, and mutate the data to reflect changes in index price and exchange rate. You will analyze correlations of stock indices among themselves and to exchange rates and create illustrative plots for each of the analyses.
Below you will find several tasks that will guide you through these steps. For the most part these tasks require you to make use of what you have learned in the sessions Data, Wrangling, Analysing, and Plotting.
Open your TheRBootcamp
R project. It should already have the folders 1_Data
and 2_Code
.
Create and work in an R Markdown document for this case study. Save your markdown file 2_Code
under the name financial_casestudy.Rmd
.
At the top of the script, load the tidyverse
package.
In this practical, you will load three external data sets \^DJI.csv
, \^GDAXI.csv
, and \^N225.csv
. However, two of these data files are not yet tidy. Specifically, \^GDAXI.csv
and \^N225.csv
include a specific character string to represent missings in the data and is not identify by R as such. To identify the NA
-character string in the data open one of them in a text viewer, (via RStudio or via, e.g., textedit). Do you see the string value that indicates missing data?
Once you have identified the character string for missing data, us the read_csv()
function to load in the stock index data sets, “^DJI.csv”, “^GDAXI.csv”, and “^N225.csv”, from your 1_Data
folder. In so doing, set an explicit na
-argument to account for the fact that “^GDAXI.csv” “^N225.csv” use a specific character string to represent missings in the data.
# Load index data from local data folder
dow <- read_csv(file = '1_Data/^DJI.csv')
dax <- read_csv(file = '1_Data/^GDAXI.csv', na = 'XXX') # 'XXX' means missing!
nik <- read_csv(file = '1_Data/^N225.csv', na = 'XXX') # 'XXX' means missing!
Load in the exchange rate data sets, euro-dollar.txt
and yen-dollar.txt
, from the 1_Data
folder as two new objects called eur_usd
and yen_usd
. To do this, use the read_delim()
-function and \t
as the delim
-argument, telling R that the data is tab-delimited.
Print the eur_usd
and yen_usd
objects. Are all the data types and variable names correct? Not quite, right?
To fix the data, first load the data again and use the col_names
-argument to explicitly assign the column names to be Date
and Rate
. This will prevent R to take names from the first row of the data.
Now, change the variable Date
to type date
. Fix this using the parse_date()
function with format = '%d %b %Y'
. This specifies the exact format the dates are formatted in. Overwrite the existing Date
-variable.
# change Date to date type in both datasets
eur_usd <- eur_usd %>%
mutate(Date = parse_date(Date, format = '%d %b %Y'))
yen_usd <- yen_usd %>%
mutate(Date = parse_date(Date, format = '%d %b %Y'))
summary
or skimr::skim()
.financial_data
that contains only the dates variable (Date
), the stock index (unadjusted) closing prices (Close
), as well as the exchange rates. Begin by joining dow
and dax
using inner_join()
, selecting only the Date
and Close
variables of each data frame. See code below.# create single data frame
financial <- dow %>%
select(Date,Close) %>%
inner_join(dax %>% select(Date, Close), by = 'Date')
financial
Inspect the data! What has R done with the names of the two Close
variables? Run the code again, this time using the suffix
-argument to give both variables suffixes preserve the origin of these variables, e.g., suffix = c(_dow','_dax')
.
Looks better now? OK, now that you know how to join two data sets repeat the steps until all five data sets are included in financial
. Remember, we only want the dates variable (Date
), the stock index (unadjusted) closing prices (Close
). Note if you have trouble fixing all variables names using the suffix
-argument you can also take of this at the end using rename()
.
Alright, now let’s create change
variables that show how the exchange rates and stock indices have moved. Use the mutate
- and the diff()
-function. The diff
computes the differences between every adjacent pair of entries in a vector. As this results in one fewer differences than there values in the vector add an NA
at the first position of the change variable à la c(NA, diff(my_variable))
.
We will be mainly interested in how stock prices and exchange rates change over the course of a year. To create a variable that codes the year mutate()
and lubridate::year(Date)
, which will extract from Date
the year information.
Finally, we want the data in the “long”, instead of the current “wide” format. Call this dataset financial_long
. In long formats variables occupy different rows rather than columns. We want to end with 4 columns: Date, year, variable and value.
# create long version of data frame
financial_long <-
financial %>%
pivot_longer(names_to = 'variable',
values_to = 'value',
cols = c(-XXX,
-XXX))
summary
or skimr::skim()
.Plot the development of each of the stock indices over the available time periods. First, select rows corresponding to the stock index prices. Then use the ggplot()
-function to start a plot. Then, Map Date
to x
and value
to y
in the aes()
-function. And, finally, add a geom_line()
. Does the plot look right?
Looked like the values of the three stock indices were somehow overlayering each other. Use + facet_grid(~variable)
to teas them apart. Also give it a slightly nicer appearance using + theme_light()
What does the plot tell you? Has there been a particular drop in any year?
Calculate the overall stock index price change per year. To do this, use group_by()
and summarise()
on the stock index change variables. Use the basic sum()
-function inside summarise()
to compute the overall change in the year. In doing this, don’t forget there were NA
’s in two of the stock index price variables. Check out the result! When was the biggest drop in stock index prices?
The results up to now suggest that modern financial markets are closely intertwined, to the extent that a change in one market can bring about a change in the markets. Evaluate this aspect of financial markets by calculating all correlations between the three stock index change variables using the cor()
-function. cor()
can take a data frame as an argument to produce the full correlation matrix among all variables in the data frame. This requires, however, that the data is stored in a “wide” format. Reactivate the old, wide financial
data set and use it inside cor()
. Before that select the variables you are interest in. Again, don’t forget about the NA
s - there is an argument for cor()
to deal with them. How closely are the stock indices related and which ones are most closely related?
Evaluate the stability of the relationships between financial markets by calculating pair-wise correlations for each year using group_by
and summarise()
. Note that here you have to specify each pairwise correlation separately inside summarise()
.
Another important aspect of financial markets are exchange rates between currencies. Generally, it is assumed that a strong economy translates into both a strong stock index and a strong currency relative to other currencies. For the end of this practical, let’s find out if that holds true our data. First, evaluate whether changes in exchange rates changes correlate with each other in the same way that stock indices did using the cor
-function.
Now, evaluate whether exchange rates vary as a function of the difference between stock indices. That is, for instance, does a large difference between Dow Jones and DAX translate into a strong Dollar relative to the EURO? According to the above intuition this should be the case. However, there is an alternative economic hypothesis. That is, foreign investors who benefit from a rise in stock index price may be motivated to sell their holdings and exchange them for their own currency to maintain a neutral position. This would, in effect, depreciate the currency at the same time as the stock index is outperforming, thus producing a negative relationship. What do you think? Ask the data.
Finally, evaluate the stability of the above relationship for each year separately. Can you make out a stable pattern? No? I guess it depends. As always.

AZOR AHAI
Created by: Ajinkya More on February 3, 2017Azor Ahai was a legendary hero who wielded a burning sword called Lightbringer, according to tales from Asshai and followers of R'hllor. In some other cultures this warrior is called Hyrkoon the Hero, Yin Tar, Neferion, and Eldric Shadowchaser.
Darkness lay over the world and a hero, Azor Ahai, was chosen to fight against it. To fight the darkness, Azor Ahai needed to forge a hero's sword. He labored for thirty days and thirty nights until it was done. However, when he went to temper it in water, the sword broke. He was not one to give up easily, so he started over...

Hi Alexander,
thanks for the patch. I just checked that it also works for GCC 4 and Intel
and Microsoft.
Maybe Guido can update the tarballs...

Subject: [Gecode] .template patch to Gecode for fl_alloc
Dear developers,
I've downloaded gecode-2005-06-21.tar.gz and tried
to compile it. Gcc 3.4.4 compiled it just excellent
but
gcc 3.2.3 failed:
g++ -DHAVE_CONFIG_H -I. -I. -I.. -I..
-DGECODE_BUILD_INT -O3 -finline-limit=3000 -DNDEBUG

Gecode::FreeList*&)'
make[2]: *** [regular/dfa.lo] Error 1
I'm sending small patch for fixing it.
With this patch g++ 3.2.3 compiles gecode ok
but consumes much more time for the job then 3.4.4 :(
G++ 3.4.4 works much faster then
The patch should work with g++ 3.4.4 so it doesn't
harm to apply it. However I can't check it for MSVC.
If MSVC failed to accept the .template construct,
conditional compilation would help.
Best wishes,
Alexander Samoilov

SLALIB --- Positional Astronomy Library


I've recently implemented an enterprise-wide solution of event
collection in our organization, using Windows' built-in mechanism called
the Windows Event Collector.
This mechanism allows you to collect events from computers running
Windows NT5+ (XP/Server 2003 and greater) into Windows NT6+
(Vista/Server 2008 and greater) machines. The only basic rules are that
the source machine should have Winrm2 installed and running on it, and
the Event Collector Service
should be running on the collector machine.
There are two methods available to complete this challenge - collector
initiated and source initiated:
| Parameter | Collector Initiated | Source Initiated |
|---|---|---|
| Socket direction (for firewall rules) | Collector --> Source | Collector --> Source |
| Initiating machine | Collector | Source |
| Authentication Type | Kerberos | Kerberos / Certificates |
| Permissions used to access event log | Configurable (system /user) |
system |
| Bulk adding methods | None (machines are added one by one) | Active Directory Groups (and Group Policy) |
Similarities
In both of the methods, some persistent open socket is created between
the collector and the source machine using WinRM (so it's firewall
friendly - one configurable port, standard HTTP messages), through which
events are transferred (as opposed to other mechanisms, which have one
machine polling another every now and then, creating a new socket during
every poll).
The events are passing encrypted through the channel (standard WinRM
encryption, either via the Kerberos authentication or using an SSL
certificate), which makes it ideal for sensitive events (like security
ones).
There can be several subscriptions to and from every server, each one
with its own configuration, including method, authentication, client
list and other settings (like heartbeat rate).
Collector Initiated
When defining such a subscription, you instruct the collector to open a
WinRM session to the source machine(s) using a specified set of
credentials (or the computer account) and ask for a subscription. The
user doesn't have to be able to read all of the event logs, but can
rather be delegated access to a specific log that needs reading (the
NETWORK SERVICE
has to be able to read that log as well, since that's
the identity WinRM is operating with). Monitoring the connection
programmatically from the collector is quite easy, because events
related are written to the
Microsoft-Windows-EventCollector/Operational
log.
Pros:
- Easy to configure and test
- Easy to centrally programmatically monitor (only read collector's log)
- Collector doesn't necessarily gain access to all events in source machine, only ones allowed by permissions on source
Source Initiated
Using this method requires one to dabble in Group Policy, because it
works by telling the source machine(s) "You should access server X and
offer it a subscription to your event logs at leisure".
The only settings configured at the source level are the collector
endpoints (server name, authentication type, port etc) and the maximum
amount of events per second allowed to pass through subscriptions
(offering the most basic performance throttling on the source side). All
other configuration is performed on the collector machine.
The Collector can be configured to allow certain sources in every
subscription. Such sources can be Kerberos-Authenticated, in which case
they can be filtered by Account or Active Directory group membership
(like allowing Domain Computers
but rejecting Domain Controllers
),
or Certificate-Authenticated, filtered by wildcard name-matching (e.g.
including all *.domain.com
and rejecting *dc*.domain.com
).
Pros:
- Can be configured on arrays of machines easily
- Can be used to collect events from machines from outside the domain
Basic Configuration
In any case, one can use either the GUI (Event Viewer from the
collector) or the CLI (WecUtil.exe
on the collector) to create a
subscription and fine tune it, including (but not limited to) the rate
in which new events arrive, the allowed/denied computers, destination
log and event query (which events will get transferred). Current
information about the subscription can be viewed using both tools,
whether it's the runtime status
in the GUI or wecutil rs
in the
CLI. I will expand this post if I see fit. Event forwarding is not
trivial, but it allows a sysadmin to centralize events for all kinds of
reasons using tools included in the Windows OS and doing so in a
standard, performance-friendly and secure way.
Have fun forwarding!


You end up in a long painful process in the Dwarf tribunal of justice. You wish decided to talk to the User instead.
Hobbit media are following the issue and making a campaign against potions coming from Wizards Kingdom. The NGO Witchcraft Without Borders is also protesting with a broom strike at Wizards University.
