Corruption occurs in both the public and private sectors. This includes media and civil society actors.
Actors can be individuals, companies, or organisations such as a political parties.
Discussion of corruption is extremely difficult as it is a hidden phenomenon in our societies.
Both parties in exchange of power for privileges want to keep their transaction secret. That makes it so difficult to establish how wide and deep corruption penetrated our economy and social life. Moreover, what for some is no more than ‘a friendly turn’ is for others ‘misbehaviour’. What in one place can be friendliness is unacceptable elsewhere.
Normal behaviour at a particular hour of the day may be unacceptable at another hour.

Big Data is a field that treats ways to analyze, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with by traditional data-processing application software. Data with many cases (rows) offer greater statistical power, while data with higher complexity (more attributes or columns) may lead to a higher false discovery rat↗1
This is a list of areas where Big Data is the most used:
For example you have NHL Statistics. In this example we will take statistics for Tampa Bay Lightnings(TBA) and Boston Bruins(BOS) from 2018-2019 season split monthly
Tampa Bay Lightning and Boston Bruins results season 2018-2019
| Team→ Month ↓ |
TBL | BOS | ||
|---|---|---|---|---|
| W | L | W | L | |
| October | 8 | 3 | 4 | 6 |
| November | 8 | 5 | 7 | 6 |
| December | 11 | 2 | 10 | 4 |
| January | 6 | 6 | 8 | 3 |
| February | 9 | 4 | 9 | 4 |
| March | 9 | 5 | 11 | 5 |
| April | 7 | 4 | 6 | 8 |
| Total | 58 | 29 | 55 | 36 |
To calculate this value we need to follow these steps:
Imagine you have hundred thousands of data like this. Big Data analysis allows you to predict certain outcomes based on previous occurrences using statistical and mathematical equations

Empty Space to test Scrolling functionality
Welcome to my search and highlight script
By Tom Alexander
Searching for terms can be done by using the browser's control (or cmd) + F feature.
The problem is that not many people know about it and therefore its usefulness goes out the window
Using this script, we can mimic that functionality by using a search box and button

Empty Space to test Scrolling functionality


QuickStart¶
Gomaps! A Google Maps web scraper for querying places on Google Maps and scraping the metadata of that search (No API key needed). This package also does geocoding, reverse geocoding and address validation! It’s essentially a lite version of the Google Maps Places API. Results of a query include the following:
Place Name
Place Google Maps URL
Place Address
Place Coordinates (lattitude/longitude)
Place Website
Place Phone Number
Place Star Rating (★★★★★)
Place Open Hours
Place Popular Times
That’s right! This can also scrape Google Maps Popular Times data! For more information about Google’s popular times data, refer to this support post: https://support.google.com/business/answer/6263531?hl=en.
Installation¶
$ pip install gomaps
Usage¶
There are two main functions to this Python package. To start, import the functions from the gomaps package.
maps_search()
¶
>>> from gomaps import maps_search
>>> results = maps_search("Tops Diner") # Returns a list like object
GoogleMapsResults([<gomaps.*GoogleMaps* object; Place-Name: Tops Diner>])
The function maps_search()
is returning a GoogleMapsResults
object that contains all the places that were found in the scrape. In this case only one place was found since the inquiry for “Tops Diner” was specific enough to have only one result.
results[0].get_values() # Populates the object's attributes & returns a dictionary
'''
{
'title': 'Tops Diner',
'url': 'https://www.google.com/maps/place/Tops+Diner/@40.7506065,-74.1639023,17z/data=!4m2!3m1!1s0x89c2547b4ec3235b:0x7342f11f69197f92!8m2!3d40.7506065!4d-74.1639023',

'coords': ('40.7506065', '-74.1639023'),
'website': 'https://www.thetopsdiner.com/',
'phone_number': '(973) 481-0490',
'rating': 4.6,
'open_hours': {'Currently': 'Closed - Opens 8AM',
'Hours': {'Friday': '8AM–11PM', 'Saturday': '8AM–11PM', 'Sunday': '8AM–11PM',
'Monday': '8AM–11PM', 'Tuesday': '8AM–11PM', 'Wednesday': '8AM–11PM', 'Thursday': '8AM–11PM'}
}
'popular_times': {
'Sunday': ['0% busy at 6 AM', '0% busy at 7 AM', '19% busy at 8 AM', '35% busy at 9 AM', '48% busy at 10 AM',
'52% busy at 11 AM', '49% busy at 12 PM', '44% busy at 1 PM', '45% busy at 2 PM', '49% busy at 3 PM',
'52% busy at 4 PM', '52% busy at 5 PM', '57% busy at 6 PM', '70% busy at 7 PM', '78% busy at 8 PM',
'66% busy at 9 PM', '39% busy at 10 PM', '0% busy at 11 PM'],
'Monday': ...
}
}
'''
Notice we index results with zero (results[0]
), in order to reference the first GoogleMaps
object of the container. From there, one is able to call the get_values()
member function of the GoogleMaps
object.
Reason why I have a separate function to get the rest of the attributes is for speed optimization. Upon initialization, a GoogleMaps
object only has the place’s url, coordinates, and title attributes.

This simple JSF 2.0 application shows how to use container defined modules to limit the size of the application package. It also shows how to use common versions of certain classes at runtime.
Applications must often depend on third party libraries. By default, Java EE packages allow you to include dependencies in a deployable unit which can lead to uncontrolled growth of the deployable unit. This can be avoided by the use of a container defined module. A modules is nothing more than a container managed binary dependency, which is shared by all deployed applications.
For more details on class loading and modules please refer to
Class Loading in AS7
This example is very simple. It declares dependency on Apache Log4j module to
allow itself to use custom logging framework.This is achieved with a simple addition to the xml file:
src/main/webapp/WEB-INF/jboss-deployment-structure.xml.
For more details about this file please refer to
JBoss Deployment Structure File
All you need to build this project is Java 6.0 (Java SDK 1.6) or better, Maven 3.0 or better.
The application this project produces is designed to be run on a JBoss AS 7 or EAP 6. The following instructions target JBoss AS 7, but they also apply to JBoss EAP 6.
With the prerequisites out of the way, you're ready to build and deploy.
First you need to start JBoss AS 7 (or EAP 6). To do this, run
$JBOSS_HOME/bin/standalone.sh
or if you are using windows
$JBOSS_HOME/bin/standalone.bat
To deploy the application, you first need to produce the archive to deploy using the following Maven goal:
mvn package
You can now deploy the artifact to JBoss AS by executing the following command:
mvn jboss-as:deploy
This will deploy target/jboss-as-log4j.war
.
The application will be running at the following URL http://localhost:8080/jboss-as-log4j/.
To undeploy from JBoss AS, run this command:
mvn jboss-as:undeploy
You can also start JBoss AS 7 and deploy the project using Eclipse. See the JBoss AS 7 Getting Started Developing Applications Guide for more information.
If you want to be able to debug into the source code or look at the Javadocs of any library in the project, you can run either of the following two commands to pull them into your local repository. The IDE should then detect them.
mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc

stalk2
below doesn't typecheck:
universe u variables (X : Type u) (P : set (set X)) definition stalk1 (x : X) := Σ U : {U : set X // x ∈ U ∧ P U}, ℕ definition stalk2 (x : X) := Σ (U : set X) (Hx : x ∈ U) (PU : P U), ℕ
red squiggle is on the sigma in stalk2
error is
type mismatch at application Σ (PU : P U), ℕ term λ (PU : P U), ℕ has type P U → Type : Type 1 but is expected to have type ?m_1 → Type : Type (max ? 1)
I think that I would rather work with stalk2 rather than stalk1
because I tend to avoid subtypes if I can
I am still a bit scared of all the up-arrows
[background : X is a topological space, P is a basis for the open sets, I'm defining the stalk of a presheaf https://stacks.math.columbia.edu/tag/009H just after 6.30.1; here's a special case https://stacks.math.columbia.edu/tag/0078 which in Lean currently looks like https://github.com/kbuzzard/lean-stacks-project/blob/16a88206397eaa664dd00cf917c78359b7119cb3/src/tag0078.lean#L9 ]
Sigma only takes two arguments. Also the type of nat doesn't depend on the set, so you may as well use prod.
@Chris Hughes It's desugared to nested sigmas. But it still doesn't typecheck because P U
does not live in Type _
. I would suggest using structures in favor of nested anything.
@Chris Hughes -- the actual type I want to make is more complex -- the nat was just a MWE of my problem. @Sebastian Ullrich I need to make a type because I am actually interested in a quotient of the type I'm trying to construct. Your observation is that this doesn't typecheck either:
definition stalk2 (x : X) (U : set X) (Hx : x ∈ U) := Σ (PU : P U), ℕ
and I don't really understand why.
But at the end of the day
I would like some sigma type so I can put an equivalence relation on it and form the quotient type.
Are you suggesting I stick with the stalk1
approach?
Presumably you prefer A -> B -> C
to A and B -> C
, i.e. here we avoid the structure [not subtype -- sorry] and prefer the "nested" approach?
No, I'm suggesting
structure stalk3 (x : X) := (U : set X) (Hx : x ∈ U) (PU : P U) (n : ℕ)
so that you don't have to worry about every component whether it should be a sigma or a prod or a pprod or ... and on top of that you get projections with meaningful names.
Oh, I see: and then this is still a type so I can still put an equivalence relation on it. I will try it this way! Thanks!
@Kevin Buzzard have you tried it? (if not, i’ll do it)
No, I've been at meetings until recently and since then I've been talking to Chris about rings
I’ll do it when i get back home then
which will happen in 15 minutes
I pushed as far as I got. Thanks.

In this chapter of the Java tutorial, we work with exceptions. Java uses exceptions to handle errors.
During the execution of our application many things might go wrong. A disk might get full and we cannot save our data. An Internet connection might go down while our application tries to connect to a site. A user fills invalid data to a form. These errors can crash the application, make it unresponsive, and in some cases even compromise the security of a system. It is a responsibility of a programmer to handle errors that can be anticipated.
In Java we recognize three kinds of exceptions: checked exceptions, unchecked exceptions and errors.
Checked exceptions are error conditions that can be anticipated and
recovered from (invalid user input, database problems, network outages, absent files).
All subclasses of Exception
except for RuntimeException
and its subclasses are checked exceptions. IOException, SQLException, or PrinterException
are examples of checked exceptions. Checked exceptions are forced by Java compiler to be either catched or declared
in the method signature (using the throws
keyword).
Unchecked exceptions are error conditions that cannot be anticipated and recovered
from. They are usually programming errors and cannot be handled at runtime.
Unchecked Exceptions are subclasses of java.lang.RuntimeException
.
ArithmeticException, NullPointerException, or BufferOverflowException belong to this
group of exceptions. Unchecked exceptions are not enforced by the Java compiler.
Errors are serious problems that programmers cannot solve. For example hardware or
system malfunctions cannot be handled by applications.
Errors are instances of the java.lang.Error
class.
Examples of errors include InternalError, OutOfMemoryError, StackOverflowError or
AssertionError.
Errors and runtime exceptions are often referred to as unchecked exceptions.
The try
, catch
and finally
keywords are used to handle exceptions. The throws
keyword is
used in method declarations to specify which exceptions are not handled within the method
but rather passed to the next higher level of the program.
The throw
keyword causes the declared exception instance to be thrown.
After the exception is thrown, the runtime system attempts to find an appropriate exception
handler. The call stack is a hierarchy of methods that are searched for the handler.
package com.zetcode; public class UncheckedException { public static void main(String[] args) { int[] n = { 5, 2, 4, 5, 6, 7, 2 }; System.out.format("The last element in the array is %d%n", n[n.length]); } }
In the above program, there is a bug. We try to access an element that does not exist. This is a programming error. There is no reason to handle this error; the code must be fixed.
System.out.format("The last element in the array is %d%n", n[n.length]);
The array indexes start from zero. Therefore, the last index is n.length - 1.
$ java com.zetcode.UncheckedException Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7 at com.zetcode.UncheckedException.main(UncheckedException.java:9)
A java.lang.ArrayIndexOutOfBoundsException is thrown by the runtime system. This is an example of an unchecked exception.
The Scanner class throws an InputMismatchException
to indicate that the token
retrieved does not match the pattern for the expected type. This exception is an example
of an unchecked exception. We are not forced to handle this exception by the compiler.
package com.zetcode; import java.util.InputMismatchException; import java.util.Scanner; import java.util.logging.Level; import java.util.logging.Logger; public class UncheckedException2 { public static void main(String[] args) { System.out.println("Enter an integer: "); try { Scanner sc = new Scanner(System.in); int x = sc.nextInt(); System.out.println(x); } catch (InputMismatchException e) { Logger.getLogger(UncheckedException2.class.getName()).log(Level.SEVERE, null, e); } } }
The error prone code is placed in the try
block. If
an exception is thrown, the code jumps to the catch
block.
The exception class that is thrown must match the exception following
the catch keyword.
try { Scanner sc = new Scanner(System.in); int x = sc.nextInt(); System.out.println(x); }
The try
keyword defines a block of statements which can throw an exception.
} catch (InputMismatchException e) { Logger.getLogger(UncheckedException2.class.getName()).log(Level.SEVERE, null, e); }
The exception is handled in the catch
block. We use the Logger
class to log the error.
The following code example connects to a MySQL database and finds out the version of the database system. Connecting to databases is error prone.
package zetcode; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; import java.util.logging.Level; import java.util.logging.Logger; public class Version { public static void main(String[] args) { Connection con = null; Statement st = null; ResultSet rs = null; String url = "jdbc:mysql://localhost:3306/testdb"; String user = "testuser"; String password = "test623"; try { con = DriverManager.getConnection(url, user, password); st = con.createStatement(); rs = st.executeQuery("SELECT VERSION()"); if (rs.next()) { System.out.println(rs.getString(1)); } } catch (SQLException ex) { Logger lgr = Logger.getLogger(Version.class.getName()); lgr.log(Level.SEVERE, ex.getMessage(), ex); } finally { try { if (rs != null) { rs.close(); } if (st != null) { st.close(); } if (con != null) { con.close(); } } catch (SQLException ex) { Logger lgr = Logger.getLogger(Version.class.getName()); lgr.log(Level.WARNING, ex.getMessage(), ex); } } } }
An SQLException
is an example of a checked exceptions. We are
forced to handle it.
try { con = DriverManager.getConnection(url, user, password); st = con.createStatement(); rs = st.executeQuery("SELECT VERSION()"); if (rs.next()) { System.out.println(rs.getString(1)); } }
The code that might lead to an error is placed in the try
block.
} catch (SQLException ex) { Logger lgr = Logger.getLogger(Version.class.getName()); lgr.log(Level.SEVERE, ex.getMessage(), ex); }
When an exception occurs, we jump to the catch
block. We handle
the exception by logging what happened.
} finally { try { if (rs != null) { rs.close(); } if (st != null) { st.close(); } if (con != null) { con.close(); } } catch (SQLException ex) { Logger lgr = Logger.getLogger(Version.class.getName()); lgr.log(Level.WARNING, ex.getMessage(), ex); } }
The finally
block is executed whether we received and exception
or not. We are trying to close the resources. Even in this process, there
might be an exception. Therefore, we have another catch
block.
The Throwable
class is the superclass of all errors and exceptions
in the Java language. Only objects that are instances of this class (or one of its subclasses)
are thrown by the Java Virtual Machine or can be thrown by the Java throw
statement.
Similarly, only this class or one of its subclasses can be the argument type in a catch clause.
Programmers can throw exceptions using the throw
keyword.
Exceptions are often handled in a different place from where they are thrown. Methods can
throw off their responsibility to handle exception by using the throws
keyword
at the end of the method definition. The keyword is followed by comma-separated list of
all exceptions thrown by that method. Thrown exceptions travel through a call stack and
look for the closest match.
package com.zetcode; import java.util.InputMismatchException; import java.util.Scanner; import java.util.logging.Level; import java.util.logging.Logger; public class ThrowingExceptions { public static void main(String[] args) { System.out.println("Enter your age: "); try { Scanner sc = new Scanner(System.in); short age = sc.nextShort(); if (age <= 0 || age > 130) { throw new IllegalArgumentException("Incorrect age"); } System.out.format("Your age is: %d %n", age); } catch (IllegalArgumentException | InputMismatchException e) { Logger.getLogger(ThrowingExceptions.class.getName()).log(Level.SEVERE, null, e); } } }
In the example, we ask the user to enter his age. We read the value and throw an exception if the value is outside the range of the expected human age.
if (age <= 0 || age > 130) { throw new IllegalArgumentException("Incorrect age"); }
An age cannot be a negative value and there is no record of a person older than
130 years. If the value is outside of this range we throw a built-in IllegalArgumentException
.
This exception is thrown to indicate that a method has been passed an illegal or
inappropriate argument.
} catch (IllegalArgumentException | InputMismatchException e) { Logger.getLogger(ThrowingExceptions.class.getName()).log(Level.SEVERE, null, e); }
Since Java 7, it is possible to catch multiple exceptions in one catch clause. However, these exceptions cannot be subclasses of each other. For example, IOException and FileNotFoundException cannot be used in one catch statement.
The following example will show how to pass the responsibility for handling exceptions to other methods.
package com.zetcode; import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; import java.util.logging.Level; import java.util.logging.Logger; public class ThrowingExceptions { public static void readFileContents(String fname) throws FileNotFoundException, IOException { BufferedReader br = new BufferedReader(new FileReader(fname)); String line; while((line = br.readLine()) != null) { System.out.println(line); } br.close(); } public static void main(String[] args) { try { readFileContents("quotes.txt"); } catch (FileNotFoundException ex) { Logger.getLogger(ThrowingExceptions.class.getName()).log(Level.SEVERE, null, ex); } catch (IOException ex) { Logger.getLogger(ThrowingExceptions.class.getName()).log(Level.SEVERE, null, ex); } } }
This example will read the contents of a text file. The responsibility to handle exceptions is delegated from the readFileContents() method to the main() method.
public static void readFileContents(String fname) throws FileNotFoundException, IOException {
When we read from a file, we deal with two checked exceptions. The readFileContents() method throws both exceptions. The task to handle these exceptions is delegated to the caller.
try { readFileContents("quotes.txt"); } catch (FileNotFoundException ex) { Logger.getLogger(ThrowingExceptions.class.getName()).log(Level.SEVERE, null, ex); } catch (IOException ex) { Logger.getLogger(ThrowingExceptions.class.getName()).log(Level.SEVERE, null, ex); }
The main() method calls the readFileContents() method. The readFileContents() method throws two checked exceptions, thereofore, the main() method must handle them.
The try-with-resources statement is a special kind of a try statement. It was introduced in Java 7. In parentheses we put one or more resources. These resources will be automatically closed at the end of the statement. We do not have to manually close the resources.
package com.zetcode; import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; import java.util.logging.Level; import java.util.logging.Logger; public class TryWithResources { public static void main(String[] args) { try (BufferedReader br = new BufferedReader(new FileReader("quotes"))) { String line; while ((line = br.readLine()) != null) { System.out.println(line); } } catch (FileNotFoundException ex) { Logger.getLogger(TryWithResources.class.getName()).log(Level.SEVERE, null, ex); } catch (IOException ex) { Logger.getLogger(TryWithResources.class.getName()).log(Level.SEVERE, null, ex); } } }
In the example, we read the contents of a file and use the try-with-resources statement.
try (BufferedReader br = new BufferedReader(new FileReader("quotes"))) { String line; while ((line = br.readLine()) != null) { System.out.println(line); } }
An opened file is a resource that must be closed. The input stream will be closed regardless of whether the try statement completes normally or abruptly.
Custom exceptions are user defined exception classes that extend either the
Exception
class or the RuntimeException
class.
The custom exception is cast off with the throw
keyword.
package com.zetcode; class BigValueException extends Exception { public BigValueException(String message) { super(message); } } public class BigValueExceptions { public static void main(String[] args) { int x = 340004; final int LIMIT = 333; try { if (x > LIMIT) { throw new BigValueException("Exceeded the maximum value"); } } catch (BigValueException e) { System.out.println(e.getMessage()); } } }
We assume that we have a situation in which we cannot deal with big numbers.
class BigValueException extends Exception { public BigValueException(String message) { super(message); } }
We have a BigValueException class. This class derives from the
built-in Exception
class. It passes the error message
to the parent class using the super
keyword.
final int LIMIT = 333;
Numbers bigger than this constant are considered to be "big" by our program.
if (x > LIMIT) { throw new BigValueException("Exceeded the maximum value"); }
If the value is bigger than the limit, we throw our custom exception. We give the exception a message "Exceeded the maximum value".
} catch (BigValueException e) { System.out.println(e.getMessage()); }
We catch the exception and print its message to the console.
In this part of the Java tutorial, we have talked about exceptions in Java.


Hi,
I re-run input file ("Water Molecule Sample Input File") from the page"Getting Started":
http://nwchemgit.github.io/index.php/Release61:Getting_Started
Command ~$ which nwchem gives: /usr/bin/nwchem , so to run input file I was using command:
mpirun -np 8 /usr/bin/nwchem h2o.nw each time changing np to 1,2,4 and 8
Results:
np=1 cpu: 15.2s wall:19.1s
np=2 cpu: 12.5s wall:24.4s
np=4 cpu: 12.5s wall:25.9s
np=8 cpu: 21.7s wall:80.9s
Since I am new to NWChem, how (and where) can I learn how to optimally run the program?
Do I have to provide any particular additional data/files?
Thank you
P.S: Bellow is copy/paste of "GA Statistics" for the last run (np=8):

De Kock: T20 captaincy still 'Faf's baby'
Cape Town - Quinton de Kock says he is still expecting Faf du Plessis to lead the Proteas in T20 cricket until next year's World Cup in Australia.
The 2020 showpiece gets underway in October next year, but there has been no official confirmation that Du Plessis will be the man in charge for the tournament.
More doubts were raised when Du Plessis missed the recently-completed T20I series in India in September, with De Kock stepping into the captaincy in his absence.
Speaking to Cricinfo, De Kock said that he would be happy to fill the role again if and when the time came.
"The way I see it is that I was just a replacement," he said.
"That's the way I took it. For now, it's still Faf's baby. But maybe if things change and they do want me to do it, then I will do it.
"For the moment, I am not looking too far ahead. I am just trying to look at how I can help out with the youngsters, with the new guys in the T20 team, and by myself, just getting better and getting ready for the T20 World Cup next year. But if that does come upon me, then I will try and grab it with both hands."
De Kock will also be captaining the Cape Town Blitz in this year's Mzansi Super League, which gets underway on November 8.
Du Plessis, meanwhile, is still the captain of the Proteas Test side while his future as ODI skipper is also in doubt following a seventh-place finish at the 2019 World Cup.

The typical usecase for for '[' and '[<-' is subscripting with positive integers,
negative integers are allowed but slower,
as logical subscripts only scalars are allowed.
The subscript can be given as a bitwhich
object.
Also ri
can be used as subscript.
Extracting from bit
and bitwhich
is faster than from logical
if positive subscripts are used.
integer subscripts make sense. Negative subscripts are converted to
positive ones, beware the RAM consumption.
The extractors [[

Desktop application developers count on a semi-infinite amount of memory for applications. This is a luxury not afforded to browser application developers. Browsers have two memory-related issues that must kept in mind when developing applications:
To better deal with memory limits, JS9 offers a number of global parameters in the JS9.globalOpts object. New values for these parameters can be added to the JS9 preference file. (See Configuring JS9 Site Preferences for more information about preferences.) The JS9.globalOpts.maxMemory parameter specifies the largest array size (in bytes) that can be allocated in the heap to hold a FITS image. The default is currently set to 750000000 (i.e., 750Mb). It is automatically set to lower values for Chrome (500000000 or 500Mb) and mobile (300000000).
Similarly, the JS9.globalOpts.image object allows you to set the max size image section that will be created from a FITS image. The general default values are {x: 0, y: 0}, where 0 values specify unlimited section size. For Chrome, the limits are set to {x: 6144, y: 6144} while for mobile devices, they are set to {x: 4096, y: 4096}. Obviously, these are just empirical guesses on our part!
When a FITS files is displayed by JS9, the file itself is maintained in memory, which is useful in many cases:
Alternatively, the JS9.globalOpts.clearImageMemory parameter can be used to specify when JS9 should automatically remove the FITS virtual file after displaying each image. Options include:
In the early days of desktop programming, memory was allocated and freed explicitly. This allowed fine-grained control over the amount of memory being used at any one time, but often led to memory leaks if the developer forgot to free previously allocated memory.
 In principle, memory gets freed when it is "no longer needed". But since the concept of "no longer needed" cannot be decided unambiguously, approximate algorithms are used.
Problems then arise because these garbage collection algorithms are only run periodically and they do not always identify all of the memory objects that can be freed. Developers often supply "hints" to the garbage collector by setting object to null or deleting large properties of an object.
Because JS9 deals with large chunks of data, garbage collection delays and misses can lead to larger than expected memory utilization. In May 2017, we found that continuously loading and closing an image was not freeing memory properly. The problem was traced to two different factors. First, especially in Chrome, the garbage collector was not properly sensing that the fileReader result memory was available for clearing. To remedy the situation, we had to delete the fileReader result object explicitly:
fileReader = new FileReader(); fileReader.onload(function(){ ... do work on the fileReader.result array ... // give the garbage collector a hint that we're done with the array delete fileReader.result; }); // start reading the file as a an array fileReader.readAsArrayBuffer(fits);See http://stackoverflow.com/questions/32102361/filereader-memory-leak for discussion of a similar problem.
Second, we found that if a continuous Javascript loop was too tight, the GC might not be run. This was especially true of Firefox. In the example below, each LoadFITS() call is making an xhr() call to check status of a FITS file, and loading the file using JS9.Load() if necessary. Since JS9.Load() runs asynchronously, there never was enough idle time to start the GC, and memory was not released properly. This situation actually could be seen using the Performance tab in the Firefox Developer Tools: the GC was run at the start of the loop, but never run again:
var timeout = 1000; setInterval(function() { LoadFITS("foo1"); LoadFITS("foo2"); }, timeout);
As a remedy, we used a longer timeout and also skipped processing for a few several cycles over time, to try to ensure that the browser had enough idle time to start the GC.
var nloop = 0; var modcycle = 1; var loopcycle = 10; var timeout = 3000; setInterval(function() { nloop++; nmod = nloop % loopcycle; // skip modcycle loops to give the GC time to be run if( nmod > modcycle ) { LoadFITS("foo1"); LoadFITS("foo2"); } // timeout should be long enough to give the GC time to be run }, timeout);
Another possible remedy is to reload the page periodically in order to reset browser memory:
var nloop = 0; var modcycle = 1; var loopcycle = 10; var timeout = 3000; var maxloop = 1800 * 1000 / timeout; setInterval(function() { nloop++; nmod = nloop % loopcycle; // reload page, approx every half hour if( nloop > maxloop ){ window.location.href = window.location.href; } // skip modcycle loops to give the GC time to be run if( nmod > modcycle ) { LoadFITS("foo1"); LoadFITS("foo2"); } // timeout should be long enough to give the GC time to be run }, timeout);
If you find that JS9 is taking much more memory than you expect, especially in situations where images are being loaded in a loop please let us know and we will try to help diagnose the problem. Note that Chrome and Firefox Memory both have Memory and Performance utilities in their Developer Tools that are very useful in understanding memory allocation issues.
Alternatively, in situations where loading images in a loop is utilizing more memory than expected, you might consider embedding JS9 inside an iframe in your web page, and reloading the JS9 page periodically. This should prevent garbage collection-related memory problems, because memory is reset each time the page is loaded.

GUIDE FOR INSTALLING nsim/nmag all FROM SOURCES (big tar ball)Table of Contents Installing Nmag all from big tarball
Installation requirementsBuilding nmag all will require approximatively 1.4 GB of harddisk space. After compilation and issuing make clean, ~550 MB will be used. (The reason for this large footprint is that the nmag archive tries to make very few assumptions on pre-installed software and hence has to bring along all the packages it depends on. This is particularly relevant for computing clusters.) Depending on hardware characteristics, compilation will usually take between 15 minutes and 2 hours. The following software packages have to be available on the build system:
On Ubuntu 11.10 you can install these requirements using: apt-get install readline-dev g++ libblas-dev libreadline-dev \ make m4 gawk zlib1g-dev readline-common liblapack-dev DownloadDownload the tarball (with a name such as nmag-0.2.0.tar.gz) from http://nmag.soton.ac.uk. (try this directory to see available tar balls. InstallationUntar the archive: $ tar xvzf nmag-0.2.0.tar.gz At this point you should know that, once the package has been compiled, you won't be able to move the nmag-0.2.0 directory to another location. Doing so would make the package unusable, since absolute paths are hard-coded inside the executables. Therefore be sure to unpack the package into an appropriate directory. Enter the directory just created by the tar command (which should be named "nmag-0.2.0"): $ cd nmag-0.2.0 and run make: $ make This command will build nsim and a number of other required packages. All the software is installed inside the directory nmag-0.2.0, so root privileges are not required (see Setting up the environment). If all goes well, nsim can be started once the 'make' command has completed: $ ./nsim/bin/nsim If this produces a prompt: >>> then nsim was compiled successfully from source. (However, the readline-dev libraries were missing, and thus the prompt is not an Interactive Python prompt.) If: $ ./nsim/bin/nsim produces a prompt like: In [1]: then readline-dev has been found during the compilation, and the prompt resembles the IPython prompt. (The interpreter can be left, as usual, by pressing Control+d, which will send an "End of File" command on its input stream.) Setting up the environmentIn order to run nsim (and related programs such as ncol, nmagpp, etc.), the shell has to know the path where to find these utilities. While it is possible to start nsim as ./nsim/bin/nsim, it is much more convenient in the long run to adjust the shell's $PATH environment variable appropriately. For the widespread bash shell, this can be done with these commands: $ cd nmag-0.2.0 # enter the main installation directory $ export PATH=`pwd`/nsim/bin:$PATH After these adjustments, nsim can be started with the command nsim without further path adjustments, regardless of the current directory. However, as this export command has to be issued within very new shell, it may make sense to add it to the shell startup command file .bashrc. Executing the command make hints in the nsim build directory will give information on how to adjust .bashrc: $ cd nmag-0.2.0 $ make hints will produce output similar to To be able to launch nsim more easily, append the following line to the end of your shell configuration file (for BASH users this file is .bashrc and can be found on your home directory ~/.bashrc): export PATH="/home/me/nmag-0.2.0/nsim/bin:$PATH" Note that there are other shells which behave differently from bash, such as in particular cshell or tcshell. For these in particular, the command to set environment variables is setenv rather than export. Testing the softwareAfter successful completion, we recommend to run a suite of unit and regression tests. If these pass (i.e. they do not fail), then everything seems to work. The test can be run by calling: $ cd nmag-0.2.0 $ make check This should take less than one minute to complete. If the output finishes with ======== tests finished: k passed, l skipped in XX.XX seconds ========== (where k and l are integers), then all seems to be well. Congratulations. While you can attempt to run the tests below, this should not be necessary. The l tests that have been skipped, take a bit more computation time (of the order of 1 hour). To test them as well, one can use: $ cd nmag-0.2.0 $ make checkslow If, after completion of either of these checks, the last line reads: ======== tests finished: k passed, m failed, l skipped in XX.XX seconds ======== then m tests have failed. You will also get further debug output following this summary line. Other available test targets are make checkmpi and make checkhlib. Please read the corresponding sections in the manual before running those -- they will fail unless the right environment has been set up. Common test failureThe following messages are typical for the output of make check if the zlib library was not present during the compilation of nmag.

The command make uninstall will remove all the files produced in the compilation phase and essentially leave the bare source tree. (The name uninstall may seem strange at first, as this way of building nsim does not install anything in system directories such as /usr/lib, but this is justified as we recursively call make uninstall on all the packages nsim depends on which will be installed into a nmag-0.2.0 subdirectory.) To completely clean nmag from the system, it is sufficient to simply remove the nmag-0.2.0 directory: $ rm -rf nmag-0.2.0 The important point to remember is that the nmag/nsim installation lives entirely within this directory and does not touch anything outside it. (The directory /tmp may be an exception, though.) Package and platform specific commentsThe packages which are more likely to be missing are gawk and readline. gawk (GNU awk) is a very common program. Most operating system distributions provide means to fetch and install a gawk package, which often already comes pre-installed. (We need gawk to compile one of the libraries [Petsc] that we depend on.) readline is commonly installed on linux systems, but often without its development files. If the directory /usr/include/readline (or /usr/local/include/readline) exists, readline development headers should be available. Otherwise, it is likely that the readline library is installed without its development files. On Debian-based Linux distributions such as Ubuntu, one can issue the command aptitude install libreadline-dev (resp. apt-get install libreadline-dev) to install the missing package. Troubleshooting issues such as ending up with a nsim_i executable which does not show a coloured prompt and misses features such as tab autocompletion are discussed in the section FAQ. The GNU compiler collection, as well as m4, tar, gzip, bzip2 should already be present if the machine already has been used for some software development. These are widespread developer tools and --- as for gawk --- the operating system distribution should provide an easy way to install them. The same holds for the lapack and the blas linear algebra libraries. Debian/UbuntuA fresh installation on debian (etch) requires the following extra packages to be installed: m4 gawk zlib1g-dev g++ libblas-dev liblapack-dev readline-common libreadline-dev make for example through executing: apt-get install readline-dev g++ libblas-dev libreadline-dev \ make m4 gawk zlib1g-dev readline-common liblapack-dev Platforms that compile Nmag from sourceThe Nmag 0.1 software has been compiled successfully (and without intervention) on the following systems:

FAQ (Frequently Asked Questions)
What is all this talk about nsim --- Isn't the package named nmag?nsim is a general purpose multiphysics simulation package. nmag is a particular application based on it, providing micromagnetism. The major effort is to install nsim. Once this is done nmag will ''just work''. It is for this reason, that there are many references to nsim in this document. What machines/operating systems does nsim compile on?This installation tool was designed to work on Linux platforms. It does not (yet) work on MS Windows, but it has been successfully used to compile nsim on Mac (both PowerPC and Intel architectures) and may work under other flavours of unix OSes. See Platforms that compile nmag from source for a list of systems on which a successful compilation has been reported. Why do I not have autocompletion and colours in nsim_i?You have just installed nsim. And nsim_i works, but the nsim_i output is not coloured and the auto-completition is not available either. Probably nsim, was compiled on a system where the readline library (or its developer files) was not installed. nsim_i needs this library for features such as command auto-completition and coloured text. One way to resolve this is to install the libreadline developer files (which should in particular provide readline.h), as explained in the section Installation requirements and then recompile from scratch. This is a short-cut to recompile just the python interpreter (i.e. the readline-dependent part): $ cd nmag-0.2.0 $ rm -rf .deps_python_* python/ $ make .deps_python_install $ make --dry-run | grep touch | sh The last line is necessary to update the dependency files: normally rebuilding python would cause all the other libraries (mpich, petsc, etc.) to be rebuilt as well, the last line is a trick to avoid this! How can I recompile the nsim package, together with all the required libraries*?Normally there should be no need to recompile the nsim package. If for some reasons you want to do so, you can issue the following commands: $ cd nmag-0.2.0 $ make uninstall $ make Note that make uninstall will remove all the files produced by a previous compilation of nsim. So, all the programs and libraries required by nsim will be rebuilt by these commands (this can take some time). Can I free some (unused) disk space after compiling nsim from source?You have compiled nsim from source and it occupies more about 1.4 GB of space on your hard-drive. Some directories which were necessary for the compilation can be removed after the compilation has finished. The command is: $ cd nmag-0.2.0 $ make clean This will free about 0.9 GB. Binary files in nmag-0.2.0/bin not workingThe installation of nsim produces a number of executables in the nmag-0.2.0/bin directory. When you try to run some of these, they do not necessarily work properly. Do you need to be concerned that there is something wrong with the installation? No, probably everything is alright. The software is not installed in the traditional unix directories (/usr/bin, /usr/lib, etc.) therefore the operating system needs to be instructed where to find executables, libraries, etc. nsim does that by calling the shell script nmag-0.2.0/exports.bash. If (for some strange reason) you want to execute the binary files under .../nmag-0.2.0/bin, these definitions have to be pre-loaded into the shell. For example, to start the Objective Caml interpreter that is compiled as part of the nsim installation from source, you could use: $ cd nmag-0.2.0 $ . exports.bash $ ./bin/ocaml This may not be necessary, but is strongly suggested. (Note that this is specific to the bash shell.) I want to recompile only nsim, how can I do this?This should not be necessary for normal users. If you are a developer and you are extending the nsim OCaml core, then this is what you need: $ cd nmag-0.2.0 $ . exports.bash $ cd nsim # enter the nsim source directory $ make These commands will only compile nsim, without reconfiguring it. If you want to reconfigure and recompile nsim use the following commands: $ cd nmag-0.2.0 $ rm nsim/config/configuration.inc $ make Note that the make command is used from the main nmag-0.2.0 directory, not nmag-0.2.0/nsim. These commands will configure nsim by running nmag-0.2.0/config/configure.py and passing to it the proper command line options to specify the paths of the required libraries. I get an HDF5-DIAG error message when trying to run an exampleThe error message reads: HDF5-DIAG: Error detected in HDF5 library version: 1.6.5 thread 0. Back trace follows. This error has been seen on a (misconfigured) linux system and is caused by the hdf5 library believing to link to libz but actually linking to a library that has the same name but different content. In particular, it seems that Matlab provides it's own libz library (which has nothing to do with the standard libz) and this library was earlier in the search path than the actual libz. A workaround is to copy the right libz (a file like /usr/lib/libz.so.*) to the nmag-0.2.0/lib directory. It seems prudent to also copy the symbolic links to this library, for example with: $ cp /usr/lib/libz.so.* nmag-0.2.0/lib Known issuesOn some Suse systems the installation failed, due to a weakness of the petsc configuration process: petsc seems unable to link against the lapack library. The problem was solved by adding an appropriate flag to the LDFLAGS environment variable: $ cd nmag-0.2.0 $ export LDFLAGS=-lgfortran $ make This is the same procedure as explained in the section Installation with just one more line to set the LDFLAGS variable. |

After building several products single handedly, which included successes and failures alike, I have identified what it takes to make a product that solves a problem well. But I still have a long way to go in my quest of learning. In my free time, I like to write blogs that could help others with specific problems that I have faced during my journey. You won't find any articles about entrepreneurship or product management or anything along those lines, as I still consider myself a beginner in these areas and I have no business in telling other people what to do.
I developed a keen interest in programming when I was 11. Since then my passion and skills have constantly evolved to give me a very strong technological foundation. I did my bachelors at Indian Institute of Information Technology, Allahabad, which is one of the best institutes in lndia for computer science and information technology. My university experience played a huge role in building the entrepreneurial skills in me, motivating me to start my own company.

NZD/USD momentum remains positive, targeting 0.6470 – Westpac
by Haresh MenghaniAnalysts at Westpac offered a brief outlook for the NZD/USD pair, which managed to regain positive traction on Monday and held steady just below last week's swing high.
Key Quotes:
"NZD/USD momentum remains positive, targeting 0.6470 during the week ahead. Fundamentals have been supportive recently: stronger housing and inflation data, rising NZ-US yield spreads thanks to the RBNZ’s less dovish outlook, and rising commodity prices over the past two months. Dairy prices have been a major part of the commodities story. Notably, whole milk powder is at a four-year high, with demand (China has dominated) and supply (globally tight) both contributing."


Sometimes I read lengthy articles or essays online and I’m curious how just how much the author has put down. I could copy the text into a text editor and find out, but why leave the browser?
It’s pretty easy to write a code snippet that gives a dumb count—meaning that it simply assumes a space indicates a new word. The answer probably won’t be exactly correct, but I’m not editing a magazine so I don’t care. Rough approximation is good enough.
The code
// initialize variables
var count = 0;
var text = '';
var words = [];
// ask for the selected text
text = document.getSelection().toString();
// is anything selected?
if (text != '') {
// make an array based on spaces as word separators
words = text.split(' ');
// the number of elements is the number of words
count = words.length;
alert(count + ' words.');
}
The bookmarklet
Simply drag the following link to your bookmarks bar (or select some text and click to see it in action): word count
For added convenience, Safari provides shortcuts to items in the bookmarks bar—if the bookmarklet is the third item on the bar, ⌘+3 will run it.
A final note
This code is too simple to bother licensing. Use as you wish.
Why?
DTS is a fancy audio format that jams extra data into generic WAV files. Because jukebox software generally doesn’t expect this, attempting to play the files results in static. Thus, we want to convert to something useful. The additional conversion to Apple Lossless is due to iTunes not having native support for any other lossless audio formats (to my knowledge).
Before we get started…
This documents what worked for me. I have no idea if this will be useful or correct for anyone else. The basic methodology used comes from dtsguide.de.vu.
Be aware that our resulting files will only be in stereo, rather than the source’s four channels!

Prepare foobar2000
- Install foobar2000 (fb2k from now on). I chose to do a single-user install of the normal package.
- Quit fb2k.
- Open fb2k’s components directory. By default, this is located at
[profile directory]/Desktop/foobar2000/components
.
- Re-open fb2k.
- Open the preferences window. The ‘Components’ section should include the DTS decoder.
Converting from DTS to FLAC
- The DTS files need to have a
.dts
file extension. If they have a .wav
extension, rename them.
- For convenience, the files (or their containing folder) should be moved to your (OS Ⅹ) desktop.
- In fb2k add the files to the playlist (File → Add Files/Add Folder → My Mac Desktop)
- Make sure the files are selected in the playlist.
- Right-click the selected files and select ‘Convert…’.
- Change the output format to FLAC.
- Create a destination folder on the OS Ⅹ desktop.
- Set this folder as fb2k’s output path.
- Go to the Processing tab.
- Enable DSP.
- Add ‘Convert 5.1 to stereo’ to the list of active DSPs.
- Optionally, enable Other → Show full status report.
- Click ‘OK’.
- You may be warned about upconverting from a lossy to lossless format. This warning is likely bogus, so ignore it.
- If this is the first time through, you will be prompted for the location of
flac.exe
.
- Conversion will begin.
- After completion, fb2k and CrossOver can be quit.
Prepare iTunes
Originally, this required more work, but the above-linked Fluke does it automatically.
Converting from FLAC to ALAC (Apple Lossless)
- Drag the FLAC files created in the previous steps onto
set OggS.app
. A log window will appear stating that everything worked; click ‘Quit’.
- In iTunes’ preferences change the importer to Apple Lossless (General → Import Settings… → Import Using: Apple Lossless Encoder).
- Select the FLAC files you want to convert.
- Right-click the selected files and select ‘Create Apple Lossless version’.
- The conversion may take a while. When it completes, remove the FLAC files from iTunes.
That’s it!
If everything’s gone well, you’ll have the converted Apple Lossless files sitting in iTunes.
Final comments
You may want to keep the original DTS files around in case they or their extra channels are eventually useful; you’ll have to decide whether disk space or quality are more important.
Originally, I attempted to do a straight conversion and retain the four channels across each step, but that didn’t quite work out. Although Apple Lossless is capable of handling up to eight channels, it seems iTunes’ converter doesn’t understand more than two. Hopefully this will change in the future.

Arc to Perlin Noise
The effect I'm trying to achieve is for the arc to fill up in a manner not dissimilar to the current Perlin Noise effect. Currently, the Noise is linked to Mouse X, however I'd like to link to it to seconds. Also, the effect produced when noise circle "doubles" on itself when completing a full circle can be further explored and used to depict hours perhaps.
