STEP 2: The Select-from-a-list approach
|
This example makes use of JavaScript to randomize the music file that is to play when the page is loaded, reloaded, or revisited later. Each time the page loads it will play a file which is randomly selected from a list of available files. There is no "memory" used to store the last file that has played, using Cookies or otherwise, so there is a possibility that the same file might be randomly selected twice in a row.
Try loading this page again.  Try this several times.
The select-from-a-list approach makes use of some slightly more advanced JavaScript than the numbered file approach. With this approach you do not need to name the music files in any particular way. All you need to do is create a list of the filenames as they appear in the folder. You then pass this list to the randomFromList function, which then returns a random file from that list. The JavaScript is shown in the source code listing below. Once again, place this JavaScript towards the end of your HTML file, where you'd like the random music file be embedded.
| |
<SCRIPT SRC="music-object.js"></SCRIPT> <SCRIPT LANGUAGE=JavaScript><!-- // function randomFromList () { var args = randomFromList.arguments; return (args.length == 0) ? '' : args [Math.round (Math.random () * (args.length - 1))]; } fileToPlay = randomFromList ( 'ambient', 'classical', 'house', 'jungle', 'lounge', 'modern-rock', 'sfx-medley', 'techno', 'trance' ); Music.magicEmbed ( 'SRC="music/' + fileToPlay + '.rmf" ' + 'AUTOSTART=TRUE ' + 'DISPLAY=SONG ' + 'MODE=INFO ' + 'LOOP=FALSE ' + 'VOLUME=100' ); // --></SCRIPT> |
In the above script there are two values which must be substituted, and a comma-separated list which must be supplied by you before using the script. These are all highlighted in red.
The part of the filename that is the same at the beginning of all the files you wish to randomize. In our example, we are specifying the folder in which all the music files are located, the folder called "music".
However, the prefix doesn't have to be restricted to specifying just the directory path of the files in your list. For instance, if your files were all located in the same folder "music" and were named "mellow-blues.rmf", "mellow-jazz.rmf", "mellow-trance.rmf", etc. then you could specify "music/mellow-" for the prefix.
The part of the filename that is the same at the end of all the files you wish to randomize. In our example, we are specifying the file type of the files we are randomizing, the extension for RMF files ".rmf".
You can also use the suffix to specify any amount of the tail end of the filename that is common to all of the files you are randomizing. For instance, if your files were named "blues-mellow.rmf", "jazz-mellow.rmf", "trance-mellow.rmf", etc. then you could specify "-mellow.rmf" for the suffix.
Beyond the prefix and suffix you need to substitute in the magicEmbed statement, there are also the parameters that you need to send to the randomFromList function - the list of music files that you would like to have randomized. The randomFromList function can accept an arbitrarily long list of filenames. Make sure each item in the list is within enclosing quotes, and if any filename contains an apostrophe (single quote) then you should be sure to use double quotes to enclose the filename.

Robert Pires outlines the type of players Arsenal need
Robert Pires suggests that Arsenal need to sign more English players in the January transfer window
by The Sport Review staffRobert Pires believes that Arsenal need to sign more English players as the January transfer window draws nearer.
The Gunners have made a stuttering start to the new Premier League season and they currently find themselves outside of the top four in the race for Champions League qualification.
Arsenal are looking to try and break back into the top four after having finished fifth last season, but they have a lot of work to do following their poor and inconsistent form this term.
With the January transfer window a matter of weeks away, attentions will inevitably turn towards the players that the Gunners could look to sign in the new year.
Former Arsenal midfielder Pires feels that the Gunners are in need of more English players because of the strong mentality they can bring to the team.
Speaking in an interview quoted by Metro, Pires said: “We need English players because we are in England and nobody else has grown up with this mentality.
“You need to be born here. It’s very nice when you get to discover new countries but for me when you play in England you need English players.
“It’s a different time. But I used to play with David Seaman, Lee Dixon, Tony Adams, Martin Keown, Ashley Cole, Ray Parlour. We’re talking about six English players in the team. We need similar players.
“Of course I respect the Arsenal philosophy but we are in the Premier League and it’s so tough every weekend.”
Arsenal will return to Premier League action next weekend when the Gunners take on Norwich City away from home on Sunday 1 December.
The Gunners will then take on Brighton and Hove Albion and West Ham United in their next two games in the Premier League as they look to keep their top-four hopes alive.

Famous for its Lion and Deer Safari, Neyyar Wildlife Sanctuary is a treat for nature enthusiasts. The park houses a crocodile farm and elephant rehabilitation centre. Ask for a guided tour of the sanctuary which is quite informative.
Kovalam is an idyllic coastal town located around 13 km from Thiruvananthapuram in Kerala. Famous for its three adjacent crescent-shaped shallow water and low tidal beaches, Kovalam is dotted with resorts and ayurvedic massage centres. Kovalam perhaps comes full circle as it is also a shopping destination given the rich spices, wooden statues and handicrafts that can make popular takeaways.
Agastyakoodam, also known as Agastya Mala Peak is the second highest peak in Kerala with an extensive height of 1868 metre.the slopes of the peak are carpeted in purple hues of orchids. Home to diverse species of fauna and rare species of medicinal herbs, the region is a hotspot for avifauna and exotic birds. The spot is considered a haven for birdwatchers.There is also a statue of him at the top where the Hindus can offer puja and prayers.

Hadoop Part 1 - Installation
Big data and machine learning are very hot topic in recent years. They are the two face of a coin, when you see the term “machine learning”, the first thing in you mine is most likely “big data”. But when you talking about “big data”, what appear in you brain first is most likely the elephant “Hadoop”.
is an open-source tool for big data analysis, initial release on Dec 2011 and the latest release is version 3.0.0. Although it is famous, it would be different for individuals to experience it’s power. It is because it requires a farm of computers to release it’s magic which most of you may never have at your home or even your office (especially in HK … :().
In this article, the way to setup this elephant under VM environment will be shared. You can have a closer look to “Hadoop” easier, and you can also use it as a test environment to evaluate your own code/job before deploy to a big farm of computer for easier debuging. Enjoy ;).
Setup a 2-node Hadoop cluster (using 2 VirtualBox VM)
Step 0: Software download location
- Download CentOS7 installation disk image (ISO) file from https://www.centos.org/download/
- Downlaod and install the latest VirtualBox from https://www.virtualbox.org/wiki/Downloads
- Download Hadoop version 3.0.0 from http://hadoop.apache.org/releases.html
- Download Oracle JDK 8 from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Step 1: Create first VM “centos7-alpha” on VirtualBox
- Create VM with settings as below
- VM Name: centos7-alpha
- Memory: 4GB
- Virtual HDD Type: VDI (VirtualBox Disk Image), Dynamically Allocated (to say disk space)
- Virtual HDD Size: 40GB (have to be large enough to install software)
- Network Adapter Type: NAT (temporary used for easier software installation with internet access)
- Boot Sequence: Optical Drive First
- OS: CentOS 7
- Hostname: centos7-alpha (<IP_ADDRESS>)
- Hostname of the other node: centos7-beta (<IP_ADDRESS>)
- VM Name: centos7-alpha
PS: Details please refer to VirtualBox doc
- Mount the DVD image file to Optical Drive, power up VM and install CentOS7
Step 2: Configure VM and install required software
- Create OS user “hadoop” with home directory located at “/home/hadoop”
Execute below command from terminal window
sudo useradd hadoop sudo passwd hadoop
PS: You can also create users during the OS installations.
- Configure the hostname to centos7-alpha
Update the file “/etc/hostname”, ie.
cat /etc/hostname centos7-alpha.com
Update the file “/etc/sysconfig/network” to add the line “HOSTNAME=centos7-alpha.com”, ie.
cat /etc/sysconfig/network # Created by anaconda HOSTNAME=centos7-alpha.com
update the file “/etc/hosts” to include IP of both hosts, ie.
cat /etc/hosts <IP_ADDRESS> localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 <IP_ADDRESS> centos7-alpha.com centos7-alpha <IP_ADDRESS> centos7-beta.com centos7-beta
Ref: Ubuntu Linux Change Hostname (computer name), Change a server’s hostname in CentOS
- Stop firewall (or open port for inter-communication across Hadoop cluster nodes),
Execute below command from terminal window
systemctl stop firewalld.service chkconfig firewalld off
PS: This have to be done with root privilege.
Ref: Resolve no route to host - Install Oracle JDK 8
Download the JDK rpm package (jdk-Bu161-linux-x64.rpm) from download link and stored in home directory of user “hadoop”
Install JDK 8, by execute below command from terminal window under home directoryrpm -UvH jdk-Bu161-linux-x64.rpm
PS: This have to be done with root privilege
Configure JDK 8 as default JVM by adding below lines to file “.bashrc” under user “hadoop”export JAVA_HOME=/usr/java/jdk1.8.0_161 export PATH=$JAVA_HOME/bin:$PATH:$HADOOP_HOME/sbin
Step 3: Install and Configure Hadoop
- Suggested hadoop settings
- Hadoop version: 3.0.0
- Hadoop home: /home/hadoop (Same as user home)
- Java version: Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
- Hadoop data dir: /home/hadoop/hadoop-infra
- Hadoop Namenode: centos7-alpha
- Install Hadoop
Download the hadoop binary tarball (hadoop-3.0.0.tar.gz) from the download link and store under home directory of user “hadoop”
Extract the hadoop binary tarball to home directory by commandtar -vzxf hadoop-3.0.0.tar.gz mv hadoop-3.0.0/* ./ rmdir hadoop-3.0.0
The directory structure will be as below
Configure the required environment variables by adding below command to file “.bashrc” under user “hadoop”
export HADOOP_HOME=/home/hadoop export HADOOP_MAPRED_HOME=$HADOOP_HOME export HADOOP_COMMON_HOME=$HADOOP_HOME export HADOOP_HDFS_HOME=$HADOOP_HOME export YARN_HOME=$HADOOP_HOME export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin export HADOOP_INSTALL=$HADOOP_HOME export LD_LIBRARY_PATH=/home/hadoop/lib/native # For Native Library
Modify “/home/hadoop/etc/hadoop/core-site.xml” as below
cat /home/hadoop/etc/hadoop/core-site.xml
Modify “/home/hadoop/etc/hadoop/hdfs-site.xml” as belowcat /home/hadoop/etc/hadoop/hdfs-site.xml
Modify “/home/hadoop/etc/hadoop/yarn-site.xml” as belowcat /home/hadoop/etc/hadoop/yarn-site.xml
The value of properties "yarn.application.classpath" have to include all jar files in below paths /home/hadoop/share/hadoop/common, /home/hadoop/share/hadoop/common/lib, /home/hadoop/share/hadoop/hdfs, /home/hadoop/share/hadoop/hdfs/lib, /home/hadoop/share/hadoop/yarn, /home/hadoop/share/hadoop/yarn/lib
Modify “/home/hadoop/etc/hadoop/mapred-site.xml” as below
cat /home/hadoop/etc/hadoop/mapred-site.xml
The value of properties "mapreduce.application.classpath" have to include all jar files in below paths /home/hadoop/share/hadoop/common, /home/hadoop/share/hadoop/common/lib, /home/hadoop/share/hadoop/hdfs, /home/hadoop/share/hadoop/hdfs/lib, /home/hadoop/share/hadoop/mapreduce
Modify “/etc/hadoop/etc/hadoop/workers” to include hostname of all nodes as below
cat /home/hadoop/etc/hadoop/workers
Up to now, the installation of VM “centos7-alpha” is completed.
Step 4: Create another node “centos7-beta”
- Clone VM “centos7-alpha” to VM “centos7-beta”
Power off VM “centos7-alpha”
Clone VM “centos7-alpha” to another VM “centos7-beta” in virtual box manager - Change the virtual network adaptor of both VM to Host-only Adaptor
Ref: Oracle VM VirtualBox: Networking options and how-to manage them
- Update the host settings
Power up VM “centos7-beta”
Configure the hostname from “centos7-alpha” to “centos7-beta” follow step above
Restart VM “centos7-beta” to make the changes effective - Configure SSH to ensure each cluster node can login itself and all other node without password
Start both VM
Ssh-key config to ensure localhost can be reached without passwordssh-keygen cp /home/hadoop.ssh/id_rsa.pub .ssh/authorized_keys
Test to login localhost
ssh localhost
Ssh-key config to ensure other node can be reach without password
ssh-copy-id <hostname-of-target-node>
Test to login other node
ssh <hostname-of-target-node>
Step 5: Startup Hadoop
- Format HDFS
Execute below command from terminal window
hdfs namenode -format
PS: This is done only on first namenode startup
- Start DFS
Execute below command from terminal window
start-dfs.sh Starting namenodes on [centos7-alpha] Starting datanodes Starting secondary namenodes [centos7-alpha.com]
After the scripted completed, verify the process as below

Scott Allan hails new Hibernian boss Jack Ross
Scott Allan lauded the man-management of Hibernian's new dugout duo Jack Ross and John Potter following an impressive 3-1 win against Motherwell.
Hibs played with a freedom and attacking fluency which was sorely missing during much of the Paul Heckingbottom reign, with goals from Christian Doidge, Florian Kamberi and Daryl Horgan doing the damage.
Although he did not get his name on the scoresheet, Allan was irrepressible throughout and has been buoyed by the opening week of the Ross era.
The fans' favourite said: "The gaffer has been really positive. His man-management skills with myself and other players have been really good.
"There's been a lot of camaraderie around the camp this week. That allows you to go and express yourself and I think a lot of players showed that on Saturday.
"It's all about positivity – you just can't buy it. It depends on certain personalities, and the manager and his assistant (Potter) have been really good for us.
"John Potter is a real livewire – really funny – and that helps too."
That sense of positivity has been heightened by Hibernian immediately moving into the top six courtesy of the win.
Allan added: "It's funny, you get two wins and suddenly it is seven unbeaten – these are the fine lines.
"But we just need to keep pressing on. We've got games on Tuesday (St Mirren) and Saturday (Kilmarnock) and we need to get up the table."
Motherwell boss Stephen Robinson was left to rue his side's lack of potency in the final third.
The visitors opened the scoring through Liam Polworth but, despite having ample possession and territory, failed to cut Hibs open again.
And Robinson hopes it proves to be a learning curve for his charges.
He added: "We had numerous half-chances that we should have put away.
"Some of our decision-making in the last third was a bit selfish when we should have rolled the ball and set someone else up.
"That's what you get with young players. They beat one man and see the glory. It's that learning curve all the time."

Club to make move for Huddersfield Town player after key man suffers ACL rupture
by Nihat Emre KocaaslanAfter Christian Luyindama picked up a serious knee injury during the recent international break, Galatasaray have entered the market for a central defender and are interested in signing Huddersfield Town’s Terence Kongolo, claim Fotomac.
Luyindama suffered an ACL rupture playing for DR Congo and it looks like he’ll only return to action next season. Subsequently the Super Lig champions are looking to bring in a replacement during the next transfer window.
One of the main candidates to replace the DR Congo international is Kongolo, and Fotomac report the Turkish giants will make a move for him in the near future.
The Former Feyenoord defender, who can also play as a left back, is said to be looking for a new team, and Fotomac report Galatasaray are monitoring the situation.
It’s claimed the Huddersfield Town player wants to play in a higher division and Gala could provide him with that opportunity, along with European football.
Kongolo has made 10 appearances for Danny Cowley’s side this season and is under contract with the Championship club until June 2022.

Basics
The source code for this module: PartI/Basics.ard
The source code for the exercises: PartI/BasicsEx.ard
In this module we explain the syntax and some key constructs of the Arend language, required to get started with writing definitions, propositions and proofs.
Arend has the following kinds of definitions: functions, data definitions, classes and records. As of now, we only consider functions and data definitions, exposition of classes and records is deferred to Records and Classes.
Some of the most basic definitions are built into the language and contained in the module Prelude. For example, Prelude contains types Nat and Int of natural and integer numbers respectively and the equality type =.
Lexical structure
All keywords in Arend start with backslash \. For example, function and data definitions start with keywords \func and \data respectively.
Numerals, if they occur in terms, are always interpreted as elements of types Nat or Int: non-negative numerals are of type Nat, negative numerals are of type Int.
Arend allows considerable amount of freedom in the choice of identifiers. With a few exceptions, names of definitions, variables
etc may contain upper or lower case letters, digits and characters from the list ~!@#$%^&*-+=<>?/|[]:_
.
Functions
Function definitions start with the keyword \func. Functions in Arend are mathematical functions. In particular, this means that they are pure and do not interact with the environment via input-output.
The simplest definition of a function must contain the name of a function
and its body. For example, the zero constant function f
without parameters can be defined as follows:
\func f => 0 -- constant function
{- Haskell:
f = 0
-}
The body of f is just the numeral 0 of type Nat. The result type Nat of f in this case is inferred by the typechecker, but it can also be specified explicitly:
\func f' : Nat => 0 -- constant with explicit type
{- Haskell:
f :: Nat
f = 0
-}
In case a function has parameters, they can be specified together with their types just after the name of the function as shown below:
\func id (x : Nat) => x -- identity function on natural numbers
\func id' (x : Nat) : Nat => x -- the same, but with explicit result type
{- Haskell:
id :: Nat -> Nat
id x = x
-}
\func foo (x _ : Nat) (_ : Int) => x -- simply returning the first argument
{- Haskell:
foo :: Nat -> Nat -> Int -> Nat
foo x y z = x
-}
As demonstrated in the definition of foo, if a parameter is not used, you can omit the specification
of its name by using the symbol _
. Also, if several consecutive parameters have the same type, they can be merged:
(x _ : Nat) is equivalent to (x : Nat) (_ : Nat).
Note that in contrast to Haskell, types of parameters should always be specified:
-- \func id'' x => x -- this definition is not correct!
{- Haskell:
id'' x = x
-}
Equivalently, parameters of a function can be moved from the signature to the body by means of lambda expressions:
-- types of parameters cannot be inferred as before
\func foo' => \lam (x _ : Nat) (_ : Int) => x
-- but types of parameters can be omitted if the result type is specified explicitly
\func foo'' : Nat -> Nat -> Int -> Nat => \lam x _ _ => x
{- Haskell:
foo'' :: Nat -> Nat -> Int -> Nat
foo'' = \x y z -> x
-}
In the examples above we specified the bodies of functions by simply writing a term after the symbol =>. Of course, there are more sophisticated ways to define the body of a function, for example, in case the function is recursive. Namely, functions can also be defined by pattern matching, we will consider such functions below.
Infix operators
By default all binary operators, just as normal functions, are prefix. In order to define an infix operator one should specify before the name of the operator one of the keywords \infix, \infixl or \infixr together with a positive integer for priority:
\func \infixl 6 $$ (x y : Nat) => x
\func test => 3 $$ 7 -- test returns 3
{- Haskell:
infixl 6 $$
($$) x y = x
test = 3 $$ 7
-}
Priority can be any positive integer between 1 and 9.
Any binary operator, even if it was not declared as infix, can be used in infix form by means of surrounding it with ` `.
\func ff (x y : Nat) => x
\func ff_test => 0 `ff` 1
{- Haskell:
ff x y = x
ff_test = 3 `ff` 7
-}
Any infix operator can also be used in the prefix from:
\func \infix 6 %% (x y : Nat) => x
\func %%-test => %% 3 7 -- no need to surround %% with ( )
{- Haskell:
infix 5 %%
(%%) x y = x
pp_test = (%%) 3 7
-}
Exercise 1: Define priorities of the functions f1, f2, f3, f4, f5 and f6 so that the function ‘test’ typechecks.
\func f1 (x y : Nat) => x
\func f2 : Nat => 0
\func f3 (f : Nat -> Nat) (z : Nat) : Int => 0
\func f4 : Nat => 0
\func f5 => f1
\func f6 => f4
\func test => f1 f2 f3 f4 f5 f6
Data definitions
Data definitions allow to define new inductive and higher-inductive types by specifying their ‘‘generating’’ elements, called constructors.
In the simplest case, when constructors do not have parameters, an inductive type is just a finite set formed by its constructors. For example, the empty type Empty, the one-element unit type Unit and the two-element type Bool of boolean values with two constructors true and false can be defined as follows:
\data Empty
{- Haskell:
data Empty
-}
\data Unit | unit
{- Haskell:
data Unit = Unit
-}
\data Bool | false | true
{- Haskell:
data Bool = False | True
-}
Defining a function on Bool naturally corresponds to specifying its values on true and false via the mechanism called pattern matching. For example, functions not and if can be defined as follows:
\func not (x : Bool) : Bool \with -- keyword \with can be omitted
| true => false
| false => true
{- Haskell:
not :: Bool -> Bool
not True = False
not False = True
-}
\func if (x : Bool) (t e : Nat) : Nat \elim x
| true => t
| false => e
{- Haskell:
if :: Bool -> Nat -> Nat -> Nat
if True t e = t
if False t e = e
-}
Typically, inductive types have constructors with parameters. In contrast to parameters of functions, it is allowed to write cons T instead of cons (_ : T).
Types of these parameters may refer to the inductive type itself, for example, as we will shortly see in case of the type of natural numbers. However, there is an important restriction: all occurrences of an inductive type in types of parameters of constructors must be strictly positive. This means that the inductive type cannot occur to the left of ->. If such definitions were allowed, it would have been possible to define the type of ‘‘all untyped lambda terms’’ K. In particular, non-terminating terms could have been coded as elements of K.
\data K | k (K -> K)
\func I => k (\lam x => x)
\func Kc => k (\lam x => k (\lam _ => x))
\func app (f a : K) : K \elim f
| k f' => f' a
\func omega => k (\lam x => app x x)
Let us turn to another example: the type of natural numbers. Definitions of the type Nat and of operations +, * from Prelude can be reproduced as follows:
\data Nat | zero | suc Nat
-- the following functions are equivalent
\func three => suc (suc (suc zero))
\func three' => 3
-- there is no limit on the size of numbers
\func bigNumber =><PHONE_NUMBER>000000000000000
\func \infixl 6 + (x y : Nat) : Nat \elim y
| 0 => x
| suc y => suc (x + y)
{- Haskell:
(+) :: Nat -> Nat -> Nat
x + Zero = x
x + Suc y = Suc (x + y)
-}
-- If n is a variable, then n + 2 evaluates to suc (suc n),
-- but 2 + n does not as it is already in the normal form.
-- This behaviour depends on the definition of +, namely,
-- the argument chosen for pattern matching.
\func \infixl 7 * (x y : Nat) : Nat \elim y
| 0 => 0
| suc y => x * y + x
{- Haskell:
(*) :: Nat -> Nat -> Nat
x * Zero = 0
x * Suc y = x * y + x
-}
This is not the only way to define a type of natural numbers. The definition above corresponds to unary representation of natural numbers. The type of binary natural numbers can be defined as follows:
\data BinNat
| zero'
| sh+1 BinNat -- x*2+1
| sh+2 BinNat -- x*2+2
Efficiency-wise this definition is obviously much better. However, it is much less convenient for proofs by induction, than the definition of Nat above. And actually the type Nat from Prelude is efficient as well, because actual implementations of arithmetic operations differ from those above and efficiently hard coded in ad hoc way.
Exercise 2: Define the function ‘if’, which takes a boolean value b and two elements of an arbitrary type A and return the first element when b equals to true and the second one otherwise.
Exercise 3: Define || via ‘if’.
Exercise 4: Define the power and the factorial functions for natural numbers.
\func \infixr 8 ^ (x y : Nat) => {?}
\func fac (x : Nat) => {?}
Exercise 5: Define mod and gcd.
Termination, div
Functions can be recursive, but they cannot refer to themselves in an arbitrary way. If the recursion were unrestricted, every proposition could have been trivially proven:
\func theorem : 0 = 1 => theorem
Moreover, the typechecking procedure in dependently typed language needs to check termination. Consequently, the language cannot be Turing complete, because typechecking becomes undecidable in this case.
Intensional Martin-Löf type theory avoids this kind of issues by ensuring that all definable functions are total, that is their evaluation terminates on every input. It is thus typical for theorem provers, that have Martin-Lof type theory in the core of their type system, to require all functions to terminate and all recursive functions to be defined by structural recursion. And this also applies to Arend.
For example, consider the division function div for natural numbers. An obvious but not correct definition may look like this:
\func div (x y : Nat) : Nat => if (x < y) 0 (suc (div (x - y) y))
There are two problems with this definition. Firstly, evaluation of div x 0 does not terminate. Secondly, the recursion is not structural. Structural recursion requires arguments of recursive calls to be structurally simpler than the original argument.
A recursive function can often be turned into structurally recursive function by introducing additional parameter, which decreases with the increase of the level of recursive calls. Initial value of this parameter can be set to an upper bound to the number of recursive steps:
\func div (x y : Nat) => div' x x y
\where
\func div' (s x y : Nat) : Nat \elim s
| 0 => 0
| suc s => if (x < y) 0 (suc (div' s (x - y) y))
Polymorphism
Some definitions are polymorphic, that is they can be naturally parameterized by a type. Such definitions can be stated with the use of the type \Type of all types. For example, the polymorphic identity function can be stated as follows:
\func id (A : \Type) (a : A) => a
{- Haskell:
id :: a -> a
id x = x
-}
\func idType : \Pi (A : \Type) (a : A) -> A => id
{- Haskell:
idType :: a -> a
idType = id
-}
The type \Pi (a : A) -> B is the type of dependent functions, which generalizes the type of ordinary functions A -> B. The codomain of a dependent function may vary dependening on the argument. For example, the type \Pi (b : Bool) -> if b Nat Bool is the type of functions which accept an argument of type Bool and return either a natural number or a boolean value, depending its argument. If we pass true to such a function, it returns an element of Nat; otherwise, it returns an element of Bool.
The type \Pi (A : \Type) (a : A) -> A can be equivalently written as \Pi (A : \Type) -> A -> A since its codomain does not depend on the second argument. This is the type of functions which accept a type A and return a function of type A -> A.
Note that \Type is not a type of all types: the famous Girard’s paradox states that intensional Martin-Lof’s type theory is inconsistent with the type of all types. This problem is solved with a hierarchy of universes, which will be discussed later. Fortunately, the user does not need to care about these levels for the most part. Levels are inferred automatically and hidden from the user, unless he or she uses forbidden circularities, in which case typechecker will generate an error.
Implicit arguments
It is quite often the case that some arguments in a function application are completely determined by others. In such cases user may ask typechecker to infer these arguments by writing _ in place of them. For example, an application of the id function defined above may look as follows:
\func idTest => id _ 0
In this case the typechecker can infer Nat as the value of the first argument, because it must be the type of the second argument, which is Nat. If the typechecker fails to infer an argument, it generates an error.
If a parameter of a definition is expected to be always or most of the times determined by others, it can be specified as implicit by surrounding it in curly braces. In this case the corresponding arguments can be skipped altogether:
\func id' {A : \Type} (a : A) => a
\func id'Test => id' 0
\func id'Test' => id' {Nat} 0 -- implicit arguments can be specified explicitly
Of course, the argument inference algorithm is limited and it cannot do too fancy things. Consider, for instance, the following example:
\func example' {n : Nat} (p : n + n = 3) => 0
In this case the inference algorithm will fail to infer n from the type of p since n occurs only inside the invocation of the function +. For example, in the invocation example’ pp, where pp : 8 = 3, the algorithm will not infer that n is 4.
On the other hand, the algorithm will be able infer n and m in the following example:
\func example'' {n m : Nat} (p : suc n = m) => 0
\func example''Test (pp : 8 = 3) => example'' pp
The difference is that in this case n and m occur in invocations of \data (= is defined via Path, which is a data type) and the constructor suc. Since \data and constructors are injective, the algorithm can always infer n and m in such cases. For example, in the invocation example’’ pp, where pp : 8 = 3, the algorithm will infer that m must be 3 and n must be 7.
List, append
By now we have discussed all the things necessary to properly define the polymorphic type of lists:
\data List (A : \Type) | nil | cons A (List A)
{- Haskell:
data List a = Nil | Cons a (List a)
-}
-- Constructors have implicit parameters for each of the parameters of data type
\func emptyList => nil {Nat}
-- Operator 'append'
\func \infixl 6 ++ {A : \Type} (xs ys : List A) : List A \elim xs
| nil => ys
| cons x xs => cons x (xs ++ ys)
{- Haskell:
(++) :: List a -> List A -> List a
Nil ++ ys = ys
cons x xs ++ ys = cons x (xs ++ ys)
-}
Exercise 6: Define the map function.
Exercise 7: Define the transpose function. It takes a list of lists considered as a matrix and returns a list of lists which represents the transposed matrix.
Tuples and Sigma-types
Given two types A and B, one can construct the type \Sigma A B of pairs (a, b), where a : A and b : B. The type \Sigma A B is equivalent to the data type defined as follows:
\data Pair | pair A B
More generally, for any family of types A1, …, An one can form the type \Sigma A1 … An of tuples (a1, …, an), where ai : Ai. A trivial example – the type \Sigma, which is equivalent to the one-element type Unit.
The tuples can be dependent in the sense that Ai can depend on a1, …, a{i-1}. Let us give a few examples of dependent \Sigma-types:
- The type \Sigma (A : \Type) (A -> A) consists of pairs (A,f), where A is a type and f is a function of type A -> A.
- The type \Sigma (b : Bool) (if b Nat Bool) consists of pairs (b,e), where b is a boolean value and the type of e is if b Nat Bool. In particular, pairs (true,7) and (false,true) belong to this type, but pairs (false,7) and (true,true) do not.
- We will see that, for every pair of natural numbers n,m : Nat, there is a type n < m of proofs that one of them is less than the other. Then we can define the type \Sigma (n : Nat) (n <= 10) which consists of natural numbers less than 10. To be more precise, it consists of pairs (n,p), where n is a natural number and p is a proof that it less than 10.
- More interesting example – the type \Sigma (n : Nat) (\Sigma (k : Nat) (n = k * k)) of natural numbers n that are full squares: its elements are pairs (n, p), where n is a natural number and p : \Sigma (k : Nat) (n = k * k) is a proof that n is a square.
If x is an element of type \Sigma A1 … An, the i-th component of x, where i is a numeral, can be accessed by the projection operator x.i. Note that eta equivalence holds for Sigma-types: if x : \Sigma A1… An, then (x.1, …, x.n) is computationally equal to x.
Type synonyms
There is no need for type synonyms in dependently types language since we can simply define a function returning the type, synonym of which is being defined:
\func NatList => List Nat
{- Haskell:
type NatList = List Nat
-}
Namespaces and modules
Each definition can be accompanied by \where block in the end. In contrast to Haskell, \where block is attached to the whole definition, not to a particular clause:
\func f => g \where \func g => 0
Definitions in \where block in almost all respects behave just as normal definitions. The only difference is that it has different namespace:
\func gTest => f.g
Alternatively, one can use \let, which is, however, limited and simpler than ‘let’ in Haskell. In Arend, \let cannot contain recursive functions and each variable can only depend on previous variables:
\func letExample => \let
| x => 1
| y => x + x
\in x + y * y
Definitions in Arend can be grouped in modules:
\module M1 \where {
\func f => 82
\func g => 77
\func h => 25
}
-- definitions f, g and h are unavailable in the current namespace
-- they should be accessed with the prefix M1.
\func moduleTest => (M1.f,M1.g,M1.h)
If a module is opened by the \open command, then its definitions can be accessed directly without the prefix:
\module M2 \where {
\open M1
\func t => f
\func t' => g
\func t'' => h
}
It is possible to open just some particular definitions in a module:
\module M3 \where {
\open M1(f,g)
\func t => f
\func t' => g
\func t'' => M1.h -- h is not opened and must be accessed with prefix
}
For every definition there is a corresponding module:
\module M4 \where {
\func functionModule => 34
\where {
\func f1 => 42
\func f2 => 61
\func f3 => 29
}
\func t => functionModule.f1
\func t' => functionModule.f2
\func t'' => (f1, f3)
\where \open functionModule(f1,f3)
-- this \open affects everything in \where-block for t''as well as t''
}
In case there are clashes between names of definitions in different modules, these definitions can be either hidden or renamed:
\module M5 \where {
\open M2 \hiding (t') -- open all definitions except for t'
\open M3 (t \as M3_t) -- open just t and rename it to M3_t
\open M4 \using (t \as M4_t) -- open all definition and rename t to M4_t
\func t'' => (M3_t, M4_t, t', t, functionModule, functionModule.f1, functionModule.f2, functionModule.f3)
\func t''' => (t'', M2.t'', M4.t'')
-- t'' in the current module clashes with t'' from M2 and M4,
-- the latter definitions should be accessed with prefix
}
The command \import X makes file X visible in the current file. Moreover, \import does everything that \open does, all the constructs for \open are applicable to \import as well:
-- The sources directory should contain a file named Test.ard (which contains definitions foobar and foobar2)
-- and a directory named TestDir with files Test.ard and Test2.ard in it.
\import Test (foobar \as foobar', foobar2)
\import TestDir.Test
-- if you want to make file visible, but do not want to make \open, you can write the following:
\import TestDir.Test2()

Clouds
Edit (pull request)In Alien 4 Cloud every deployment is done on what we call a Cloud. Clouds are used to describe a logical deployment target that offers a set of resources (e.g. machines, storage, network, firewalls etc.). A cloud may refer to a real cloud, to a specific tenant on a cloud, to a set of physical machines (BYON), or even docker containers.
You can create and configure as many clouds as you like to have as many deployment targets (environments) as required.
For example a cloud can refer to an Amazon configuration using a specific account while another cloud could be configured to work on a specific Tenant on an OpenStack cloud.
To make it simple a cloud is a logical set of available resources that Alien 4 Cloud can use to deploy applications. In order to do so A4C relies on orchestration technologies that are easily pluggable.
Note
We are currently supporting the opensource orchestrators cloudify 2 and cloudify 3 (Full re-written engine with new DSL - much better and flexible but that we felt prior to the up-comming 3.2 a bit light for production use).
Role and security
Only a user with the global ADMIN role can define, configure, enable and grant deployment role to other users or groups on a cloud.
To find more on clouds and how to configure them in Alien 4 Cloud please look at the Getting started guide if you don’t already have an Alien instance running and at the cloud setup guide in order to learn cloud configuration.
A cloud supported the following resources :
- Compute: TOSCA node who represents a real or virtual machine or ‘server’
- Storage: TOSCA node who represents a server-local block storage device
- Availability zone: Alien feature to separate your node into separate geographic area
- Network: Alien feature based on the TOSCA expressiveness to control the mapping of software component to the network


The Sanskrit term Ayurveda translates to “knowledge of life,” and the principles of this ancient wisdom remind us that the entire web of life is intricately interwoven. With a unique emphasis on total wellness, the art and science of Ayurveda
work to harmonize our internal and external worlds.
Our five senses serve as the portals between the internal and external realms, as the five great elements of ether, air, fire, water, and earth dance the dance of creation around and within us. Ayurveda groups these five elements
into three basic types of energy and functional principles that are present in everybody and everything. Since there are no single words in English to describe these principles; we use the Sanskrit words Vata, Pitta, and Kapha to describe
their combinations.
Everything that we experience, be it a physical substance, a thought, or emotion, has certain qualities. The ancient texts of Ayurveda classify these qualities — called gunas in Sanskrit — into 10 pairs of opposites, making 20 qualities
total (for example, heavy vs. light). Theoretically, everything in the universe can be described in terms of these gunas, or qualities, including the doshas. The foundation of Ayurvedic treatment relies upon recognizing when gunas have
become excessive or deficient, as this is known to cause doshic imbalance and lead to disease. Ayurveda applies the opposite qualities to return to balance.

Create an argument function
createArgFunction( functionName, excludeArgs = c(), includeArgs = NULL, addArgs = list(), rCode = c(), newName )
| functionName | The name of the function for which we want to create an args function. |
|---|---|
| excludeArgs | Exclude these arguments from appearing in the args function. |
| includeArgs | Include these arguments in the args function. |
| addArgs | Add these arguments to the args functions. Defined as a list with format name = default. |

5 MOST STRIKING TALKS FROM
OFFF 2017 BARCELONA
Highlights from the Talks of the Top Designers at OFFF 2017 Barcelona
INTERACTION DESIGN
OFFF invites the most influential designers from all around the world to give a speech to share their work and expertise. It's a must-go event for designers, students and anyone interested in design. The three days we have spent at OFFF Barcelona 2017 has changed our perspective and taught us invaluable lessons. Read on to see the highlights from the 5 most striking talks given by the speakers this year. 1. On Storytelling - Imaginary Forces Book design is the art of incorporating the content, style, format, design, and sequence of the various components of a book into a coherent whole. In the words of Jan Tschichold, "methods and rules upon which it is impossible to improve, have been developed over centuries. To produce perfect books, these rules have to be brought back to life and applied." Front matter, or preliminaries, is the first section of a book, and is usually the smallest section in terms of the number of pages. Each page is counted, but no folio or page number is expressed, or printed, on either display pages or blank pages. Michelle Dougherty is the director of the main titles of many popular TV series; Stranger Things, Black Sails and Jessica Jones are only some of the titles she has worked on. As Karin and Michelle explained their works and process, they talked about each project in detail.
As Karin was explaining her reasoning behind the work she created for the God of War III trailer, she said she realized that there needed to be a story behind the main character. In order to make the audience empathize with the protagonist, Kratos, she decided to tell the story of his past. In order to understand his fight, Karin thought it was necessary to understand how he came to be the person he is now. As a result, the trailer for the game tells the story of how Kratos killed her child and wife, suffering from his tormented soul for years until one day he became the God of War.
"Methods and rules upon which it is impossible to improve, have been developed over centuries. To produce perfect books, these rules have to be brought back to life and applied."

I'm still not 100 percent sure what I want to do for the next 50 years of my life. I know I like coding and I could see myself doing it for a long time but I have so many goals and dreams of what I want to do. This seems like a really good start. I could see myself following the tech career path and doing this. In my wildest dreams, someday I really get crazy into coding and work for Google, or even create my own huge search engine that really takes off. For now I think I would like to build websites for local businesses and build a client list. Eventually I may work up a big enough base that I can continue freelancing and hopefully become able to support myself more. After this certificate program I think I might use the transfer credits and finish my degree at Dixie State.
I am hugely family-oriented and I want to invest more time into my family. I want to one day be able to support my dad and buy him his own house. I want to get him all the Oakland Raiders(soon to be Vegas, he's not happy about it) season tickets money can buy.I want to buy my own house in cash and stop paying rent every month; even just since August I am exhausted of being an adult. My main goal for adulthood is just to not be worried about my bank account and to be able to help my family with whatever they need.

bool apache_child_terminate ( void )
apache_child_terminate() will register the Apache process executing the current PHP request for termination once execution of PHP code is completed. It may be used to terminate a process after a script with high memory consumption has been run as memory will usually only be freed internally but not given back to the operating system.
Returns TRUE if PHP is running as an Apache 1 module, the Apache version is non-multithreaded, and the child_terminate PHP directive is enabled (disabled by default). If these conditions are not met, FALSE is returned and an error of level E_WARNING is generated.

Solution
We designed a dashboard to display performance metrics so engineers
could quickly review data and errors at a glance. There will be 3
different visuals for the Performance pages: Chlorine Generated,
Device State, and Indicator Summary.
The “Device State” bar graph displays the status of each device --
whether it is in or out of operation, or in an error state.
The “Indicator Summary” table displays all the indicators (ex.
salinity and brine temperature) that the engineering team will
need to ensure all devices are running smoothly.
The “Chlorine Generated” bar
graph displays the amount of chlorine generated of all 50 devices.
The “Device State” bar graph displays the status of each device --
whether it is in or out of operation, or in an error state.
The “Indicator Summary” table displays all the indicators (ex.
salinity and brine temperature) that the engineering team will
need to ensure all devices are running smoothly.


Implementation Dependent Behaviour
The following aspects of the ECMAScript 2022 Internationalization API Specification are implementation dependent:
-
In Locale:
-
Support for the Unicode extensions keys *"kf"*, *"kn"* and the parallel options properties *"caseFirst"*, *"numeric"* ()
-
The set of preferred calendars (), collations (), hour cycles (), numbering systems (), and time zones () per locale
-
The default general ordering of characters (characterOrder) within a line per locale ()
-
The 'first' day of a week, the minimal days required in the first week of a month or year, and which days of the week are considered as part of the 'weekend', for calendar purposes, per locale ()

I have been using C# and .NET since the first beta versions came out in 2000, and my current focus is mostly around ASP.NET Core.
I am responsible for maintaining all the .NET related SDKs and sample applications for Auth0, so I am very familiar with implementing authentication and authorization in ASP.NET and other .NET applications.
I blog on this website about .NET related topics and also curate ASP.NET Weekly, which is a weekly digest of all the best ASP.NET related news and blog posts.
The following are some of my primary technologies I am familiar with:
My hourly rate for work is US$ 60 - 80 per hour depending on the type and duration of the project.
I am looking for short term projects (up to about 6 months in length) where I can work remotely. I am currently only available on a part-time basis, but for the right project I may consider something more permanent.
I would be an ideal fit if you are looking for a part-time developer to carry forward a smaller part of a larger project, or a smaller isolated project like a Proof of Concept.
If you want to get in contact to enquire about hiring me, please send an email to jerrie@jerriepelser.com.


Navigating Vim may seem daunting at first, but once you're through the learning curve, it's very easy and efficient. Let's start with some basic navigation commands.
Typing h, i, j, and k (case-sensitive) will move you one space left, right, down, and up, respectively. For each of those, you can type a number in front of the command to specify how many spaces you'd like to move in that given direction. For example, typing 3i will move you three spaces to the right.
Typing e will move you to the end of a word, and w will move you to the beginning of the next word. Typing b will move you backwards to the beginning of a word.
To move to the end of a line, type $, and to move to the beginning of a line, type 0. Typing gg will move you to the first line, and typing G will move you to the last line. If you'd like to move to a certain line number, type the line number before G to specify that is the corresponding line number to which you would like to move. For example, if you type 45G, you will move to line 45.
To save the current file, type :w. An alternative to this would be to type :update. The difference is that :w will save the file even if it has not been changed since the most recent save, while :update will only save the file if it has been changed since the most recent save. Typing :w! will additionally override any problems found by Vim while saving the file. To save all open and changed files, type :wa. If you want to name the file and save it at the same time, type :w "filename". This is the equivalent to the "Save As" option found in other programs, and appropriately works interchangeably with typing :saveas "filename".
To quit Vim, type :q. If you'd like to quit and also save the current file at the same time, type :wq. To quit and save all open and changed files, type :xa. Similarly, typing :qa will close all open files and quit Vim unless there are unsaved changes. Typing :q! will quit Vim without saving any changes (be careful when using this command).

The Hazleton Pumps is the world leaders in slurry pumping of various different mining, utilities, froth and process plant operations. Hazleton with over 30 years’ experience is more than just a pump company, in supplying Pump Selection Consulting, System Design Developing, Pump Repair Facility and Pump Hire Services for all industries would help to find the correct solution for every pumping requirements for all types of applications
Installation and commissioning of pump systems and controls i.e. electrical control panels require engineering expertise and specialist advice. It is, therefore, crucial that any new and re-furbished pump or pumping system is commissioned by our experts.
We provide a comprehensive evaluation of the pumping problem before quoting, and a commissioning service once the system had been installed. Ensuring that the installation is up and running quickly and efficiently. Additional advice could be provided with regards to the installation, training, and maintenance
We are equipped with the latest design software for both mechanical and electrical designs as well as pump control systems. The combination of experienced, expertise and the latest design software allows us to offer the optimum pumping system designs.
When a standard pump is not available we can design and manufacture specialised pumps to accommodate most applications and specific duties. This has been proved to be more economical than using a pump that is not completely suited for application
Hazleton Pumps specialises in refurbishment of all types of pumps, electric motors and switchgear and is equipped to do flameproof verification on refurbished pumps, electrical motors and switchgear.
Hazleton Pumps test and verify the duty of all pumps built and refurbished to BS ISO9906:2002 in order to insure the pump would operate to the designed specifications. All pumps above 132 kW is fully tested and certified by an external testing authority i.e. the SABS at their testing facility in Pretoria
Due to high capital cost involved when purchasing a pumping system that does not function effectively, it is not always financially feasible to replace the pumping system therefore Hazleton Pumps is involved with upgrading of all types and makes of pumps and specialises in the improvement of the pumps reliability and efficiency
Training could be done on-site or should more in depth training regarding pumps and pumps systems be required this could also be provided. Please contact our sales department for more details.
Staying abreast of new technologies and innovations in the industry and apply these to our pumping solutions for optimal functionality and durability. Hazleton Pumps does not just sell pumps; we specialises in selling complete pumping solutions, selecting the correct pump for the desired application.
For expert advice contact us with any questions you might have regarding the performance of your equipment or any other pumping problem


This form lets you create an add-on containing a Jive Simple Stream Integration. A Simple Stream Integration is an integration between a third party webhook and a Jive activity stream. For more details about this feature, refer to Developing Simple Stream Integrations in the Jive Community.
This JavaScript function executes whenever the third party webhook calls the Jive URL. Within this function, you should parse the contents of the incoming body and then call the callback function with JSON that complies with Jive's activity stream format.
function transform(body, headers, options, callback) {
}
Update the Sample Input with data that should come from the third party webhook. You can then test your transform function by clicking the Run Transform button. The Resulting Output text area contains the output of your transform function; it should be in the Jive activity stream format. Verify that the two tests below pass before downloading the add-on package.
| Sample Input |
Resulting Output |
Transform Function Test: N/A
Output Validation Test: N/A
After downloading this add-on package, upload it into your Jive community. Check out Developing Simple Stream Integrations for more information.

| output scaling properties More... | |
| void(* wl_output_listener::done) (void *data, struct wl_output *wl_output) |
sent all information about output
This event is sent after all other properties have been sent after binding to the output object and after any other property changes done after that. This allows changes to the output properties to be seen as atomic, even if they happen via multiple events.
| void(* wl_output_listener::geometry) (void *data, struct wl_output *wl_output, int32_t x, int32_t y, int32_t physical_width, int32_t physical_height, int32_t subpixel, const char *make, const char *model, int32_t transform) |
properties of the output
The geometry event describes geometric properties of the output. The event is sent when binding to the output object and whenever any of the properties change.
The physical size can be set to zero if it doesn't make sense for this output (e.g. for projectors or virtual outputs).
| x | x position within the global compositor space |
| y | y position within the global compositor space |
| physical_width | width in millimeters of the output |
| physical_height | height in millimeters of the output |
| subpixel | subpixel orientation of the output |
| make | textual description of the manufacturer |
| model | textual description of the model |
| transform | transform that maps framebuffer to output |
| void(* wl_output_listener::mode) (void *data, struct wl_output *wl_output, uint32_t flags, int32_t width, int32_t height, int32_t refresh) |
advertise available modes for the output
The mode event describes an available mode for the output.
The event is sent when binding to the output object and there will always be one mode, the current mode. The event is sent again if an output changes mode, for the mode that is now current. In other words, the current mode is always the last mode that was received with the current flag set.
The size of a mode is given in physical hardware units of the output device. This is not necessarily the same as the output size in the global compositor space. For instance, the output may be scaled, as described in wl_output.scale, or transformed, as described in wl_output.transform.
| flags | bitfield of mode flags |
| width | width of the mode in hardware units |
| height | height of the mode in hardware units |
| refresh | vertical refresh rate in mHz |
| void(* wl_output_listener::scale) (void *data, struct wl_output *wl_output, int32_t factor) |
output scaling properties
This event contains scaling geometry information that is not in the geometry event. It may be sent after binding the output object or if the output scale changes later. If it is not sent, the client should assume a scale of 1.
A scale larger than 1 means that the compositor will automatically scale surface buffers by this amount when rendering. This is used for very high resolution displays where applications rendering at the native resolution would be too small to be legible.
It is intended that scaling aware clients track the current output of a surface, and if it is on a scaled output it should use wl_surface.set_buffer_scale with the scale of the output. That way the compositor can avoid scaling the surface, and the client can supply a higher detail image.

Welcome to Phase 5 of the experiment!
You have completed Phase 4 and will now start Phase 5. The setup is the same, with the exception that now you will be in groups of three. Within your group you can see each other’s risk. You will vote on whether you wish to collaborate in adaptation or not. If the group decision is to collaborate, you may incur a different adaptation cost than in Phase 1. If the decision is not to collaborate, you make your individual adaptation choice as in Phase 1.
At the beginning of each period, you are informed of your individual risk. You are also informed of the risk incurred by the other group members. This may be 1, 5 or 10 percent, depending on how vulnerable each individual home is to climate change.
You and two other home owners can now vote on whether you would like to collaborate in taking an adaptation measure. If all three vote for collaborative adaptation, then you take adaptive measures in the current period. The cost of collaborative adaptation is 100 tokens for each group member, regardless of whether a storm surge takes place or not.
If the result of the vote is no collaboration, you can still decide whether you would like to take adaptation measures on your own. Then, it is as in Phase 1 and 2.
