CP 2006
Call for Applications to Doctoral Programme
Twelfth International Conference on Principles and Practice of
Constraint Programming
September 25-29, 2006
Nantes, France
CP 2006 invites Ph.D. students to apply for the Doctoral Programme, a forum
held during the CP conference which provides an opportunity for a group of
Ph.D. students to achieve visibility and discuss their research interests
and career objectives with each other and established researchers in
Constraint Programming and its related fields. After successful Doctoral
Programmes in previous years, it is being run again this year for the sixth
time.
The aims of the Doctoral Programme are the following:
- to provide a forum for Ph.D. students to present their current
research,
and receive feedback from other students and senior researchers;
- to promote contacts among Ph.D. students and senior researchers
working in the same area;
- to exchange research experience;
- to support Ph.D. students with information and advice on academic,
research and industrial careers;
- and to financially support its participants.
The programme will consist of students' presentations and/or posters, and
tutorials given by senior researchers in the field. In addition, each
student will be matched to a mentor who is a senior researcher with similar
research interests and who can advise the student on his/her research
progress.
Participation and Financial Support Rules
=========================================
- Applicants will be selected to participate in the Doctoral Programme
based on the
quality of their submissions;
- participants who have never attended CP Doctoral Programmes will be
given higher
priority for financial support;
- participants who have already attended past CP Doctoral Programmes
will be given
financial support if funding is available. In this case, priority is
given to students
who received less support from the DP in previous years.
Financial support consists in free conference registration and
accommodation. NOTE that only the students who applied and got accepted for
participation in the Doctoral Programme are subject to financial support.
Paper Availability
==================
Student papers will be available during the conference and on the
Conference/Doctoral Programme websites.
Submissions
===========
We encourage submissions from Ph.D. students at any level, and from any
topic area and methodology within Constraint Programming and its related
fields. On the basis of the submissions, the Organizing Committee will
select a group of students that will be invited to present their work during
the Doctoral Programme, either as a presentation or a poster. We expect a
commitment from all participating students to attend the entire Doctoral
Programme.
Applicants should submit a paper electronically using the electronic
submission form at:
http://www.softconf.com/start/CP_PHD06/submit.html
The paper should be a maximum of 6 pages in length and should follow the
usual LNCS style format at:
http://www.springer.de/comp/lncs/authors.html.
NOTE that the page limit is strict and longer papers will NOT be reviewed.
The paper should be sent either as a PostScript or as a Pdf file. It should
describe original, unpublished work, completed or in progress, that is part
of the doctoral work of the student(s). The authors should be formatted as:
Student(s): ...
Supervisor(s): ...
If an extended version of the paper is also submitted to the technical
programme, THIS MUST BE INDICATED in the ABSTRACT of the paper. Double
submission is acceptable, but if the paper is accepted also for the
technical programme, the student will present the work only in the technical
programme sessions and not during the Doctoral Programme. The papers of the
students accepted for participation to the Doctoral Programme will be made
available on the web.
In addition, the dissertation advisor should send a letter of recommendation
by e-mail to cp-phd2006 @ deis.unibo.it. The letter
should:
- confirm that the applicant is a Ph.D. student working in Constraint
Programming
or its related fields;
- indicate whether the student has already benefitted from the past CP
Doctoral Programmes,
and if yes how many times;
- include the expected date for thesis submission;
- and the motivation/expected benefit for the student to attend the
Doctoral Programme.
This letter can be sent in as either a text or a PostScript or a Pdf file.

Emilia Clarke praises ‘gracious’ paramedics who helped her after brain aneurysm
Emilia Clarke has praised the paramedics who kept her laughing on the way to hospital after she suffered a ruptured brain aneurysm.
The Game Of Thrones star has previously told how she had a potentially fatal brain haemorrhage in 2011 before having surgery that left her unable to recall her own name. In 2013, she had surgery for a second aneurysm on the other side of her brain.
Clarke, 33, told People magazine of her experience in 2011: “It was a brain aneurysm that ruptured and it was pretty traumatic.
“The paramedics were unbelievable. They’d given me drugs so I was in less pain, wrapped me up like a tortilla and made me laugh the whole way to the hospital.
“There I was, bleeding in the brain, and there we were in this ambulance having an absolute giggle. They were so gracious.”
“Every single nurse I came across was so kind,” said the actress.
“It’s why I became ambassador to the Royal College of Nursing in 2018. Nurses are the unsung heroes, they’re at people’s most frightening moments.”
After her health crisis, Clarke launched SameYou, a charity aimed at supporting people with brain injuries.
The actress – who played Daenerys Targaryen in the fantasy TV series – said: “People’s lives are transformed completely after a brain injury and the core of our work is recovery — it’s not just the first weeks that you need help, you still need help for years.
“I wanted to match someone with a consistent person who has the answers and can hold their hand and tell them that they’re not alone. Being there when someone is scared, confused or angry is one of the kindest things you can do.”


cmake_parse_arguments¶
Parse function or macro arguments.
cmake_parse_arguments(<prefix> <options> <one_value_keywords>
<multi_value_keywords> <args>...)
cmake_parse_arguments(PARSE_ARGV <N> <prefix> <options>
<one_value_keywords> <multi_value_keywords>)
This command is for use in macros or functions. It processes the arguments given to that macro or function, and defines a set of variables which hold the values of the respective options.
The first signature reads processes arguments passed in the <args>...
.
This may be used in either a macro()
or a function()
.
The PARSE_ARGV
signature is only for use in a function()
body. In this case the arguments that are parsed come from the
ARGV#
variables of the calling function. The parsing starts with
the <N>
-th argument, where <N>
is an unsigned integer. This allows for
the values to have special characters like ;
in them.
The <options>
argument contains all options for the respective macro,
i.e. keywords which can be used when calling the macro without any value
following, like e.g. the OPTIONAL
keyword of the install()
command.
The <one_value_keywords>
argument contains all keywords for this macro
which are followed by one value, like e.g. DESTINATION
keyword of the
install()
command.
The <multi_value_keywords>
argument contains all keywords for this
macro which can be followed by more than one value, like e.g. the
TARGETS
or FILES
keywords of the install()
command.
Note
All keywords shall be unique. I.e. every keyword shall only be specified
once in either <options>
, <one_value_keywords>
or
<multi_value_keywords>
. A warning will be emitted if uniqueness is
violated.
When done, cmake_parse_arguments
will consider for each of the
keywords listed in <options>
, <one_value_keywords>
and
<multi_value_keywords>
a variable composed of the given <prefix>
followed by "_"
and the name of the respective keyword. These
variables will then hold the respective value from the argument list
or be undefined if the associated option could not be found.
For the <options>
keywords, these will always be defined,
to TRUE
or FALSE
, whether the option is in the argument list or not.
All remaining arguments are collected in a variable
<prefix>_UNPARSED_ARGUMENTS
that will be undefined if all arguments
were recognized. This can be checked afterwards to see
whether your macro was called with unrecognized parameters.
<one_value_keywords>
and <multi_value_keywords>
that were given no
values at all are collected in a variable <prefix>_KEYWORDS_MISSING_VALUES
that will be undefined if all keywords received values. This can be checked
to see if there were keywords without any values given.
Consider the following example macro, my_install()
, which takes similar
arguments to the real install()
command:
macro(my_install)
set(options OPTIONAL FAST)
set(oneValueArgs DESTINATION RENAME)
set(multiValueArgs TARGETS CONFIGURATIONS)
cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}"
"${multiValueArgs}" ${ARGN} )
# ...
Assume my_install()
has been called like this:
my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub CONFIGURATIONS)
After the cmake_parse_arguments
call the macro will have set or undefined
the following variables:
MY_INSTALL_OPTIONAL = TRUE
MY_INSTALL_FAST = FALSE # was not used in call to my_install
MY_INSTALL_DESTINATION = "bin"
MY_INSTALL_RENAME <UNDEFINED> # was not used
MY_INSTALL_TARGETS = "foo;bar"
MY_INSTALL_CONFIGURATIONS <UNDEFINED> # was not used
MY_INSTALL_UNPARSED_ARGUMENTS = "blub" # nothing expected after "OPTIONAL"
MY_INSTALL_KEYWORDS_MISSING_VALUES = "CONFIGURATIONS"
# No value for "CONFIGURATIONS" given
You can then continue and process these variables.
Keywords terminate lists of values, e.g. if directly after a
one_value_keyword
another recognized keyword follows, this is
interpreted as the beginning of the new option. E.g.
my_install(TARGETS foo DESTINATION OPTIONAL)
would result in
MY_INSTALL_DESTINATION
set to "OPTIONAL"
, but as OPTIONAL
is a keyword itself MY_INSTALL_DESTINATION
will be empty (but added
to MY_INSTALL_KEYWORDS_MISSING_VALUES
) and MY_INSTALL_OPTIONAL
will
therefore be set to TRUE
.

We replaced MQL4/Libraries/OTMql4/libzmq.dll with
libzmq-v100-mt-2_2_0.dll that we compiled with MSVC2010
according to the original instructions. These are being tracked in
https://github.com/OpenTrading/mql4zmq/
We tried using those same instructions to compile against v4.0.4,
and sending from Mt4 works, but we still have to rewrite the glue code
for the version 4 changes. We'll test v2.2.0 for a while first.

If You Know This,You Must Have NO GF
问题描述 :
Now let’s have a look at the grammar of makefile. Please note that in this problem, we have simplified the problem a lot, so read carefully, especially when you are familiar with such things. In this problem, makefile contains three kinds of statements:
1. Target: [component ...]
This is a statement to define a target. To build "Target", you have to generate all the files in [component ...] at first. Here is an example:
a.o: a.cc b.cc
Which means if you want to generate file a.o, you have to make sure that there are already file a.cc and b.cc in the directory.
Each component(including the target itself) will be a string which is a legal file’s name, as "aaa" or "aaa.bbb". They will be separated by some spaces.
A legal file’s name will only contain letters (upper case and lower case), numbers and only contain one dot (.).
There won’t be two Targets sharing a same file name. Also relations between files won’t form a circle.
2. Commands
This is a command shows how to build the Target, usually written after statement 1. Here is an example:
g++ a.o b.o -o main
Note this kind of commands will have *FOUR SPACES* at the front of the line.
There maybe two or more commands after statement 1.
3. Comments
Comments begin with character ‘#’, which should be ignored. Note that ‘#’ can appear in any place in the line, and all character after ‘#’ in the line shall be ignored. Here is an example:
a.o: a.cc b.cc #hello world!
This should be regarded as
a.o: a.cc b.cc
Sometimes you may find a statement is too long to be written in a single line. You can add a ‘\’ at the end of the line, indicating that there are still part of statement at the next line. Here is an example:
main: a.o\
b.o
g++ a.o b.o -o main
This equals to the statement
main: a.o b.o
g++ a.o b.o -o main
Notice that ‘\’ will only appear at end of the line and not appear in comments.
Now this is all a makefile will have.
You have a makefile, and you will execute Q "make" commands one by one. There are already some files in the directory.
The make command is like this:
make Target
Which will try to generate a file named "Target".
If there are no such "Target" defined in the makefile, or it cannot be built since lack of files. This command will not get executed.
Your task is, after executing each command, how many new files will appear in the directory?
输入:
Then some lines come, indicating the content of makefile. A string "====" indicating the end of makefile. each line is no longer than 1000 characters. the size of makefile will not exceed 1MB.
There are at most 500 target in the Makefile.
Then comes a single line with a number N(N <= 500). Which is the number of files that are already in the directory.
Then come N lines each with a file name.
Then comes a single line with a number Q(Q <= 500). Which is the number of command you are going to execute.
Then come Q lines each with a command, within the pattern "make Target".
输出:

As we can see here, the number of diagnosed Covid-19 cases in Ireland has grown exponentially, reaching 24274 on 19-May. On the brightside, however, we can see that the rate of infection has fallen drastically; as the impact of social distancing translates into each infected person infecting fewer and fewer other people.

My girlfriend and I broke up during my Junior year of college after a wonderful 2 year relationship. We both were getting scared that the next step was probably marriage, and that freaked us out. So we ended it.
The problem was, we had already saved money and bought tickets to travel together in Europe for 3 months the following summer. I decided that I wasn't going to give up the trip, and she decided the same. We spoke only once or twice in the 4 months leading up to our trip.
Once we got to Europe, the chemistry was back, but since we were both dating other people back home, there was definitely some jealousy. Plus, I had been somewhat unfaithful during our 2 years together, and I think she suspected that. I was suspicious of some things she had done as well. All of these things made for an uncomfortable situation, and made a future romatic relationship all but impossible.
We decided to go to the Love Parade in Berlin, Germany. The Love Parade is the world's largest techno festival. Once a year, sometime in July, the world's best DJs and 1 million techno fans take over the city and party non-stop for 3 days. The city hosts roughly 15 raves each night. It was AMAZING!!!
We picked up some E in Amsterdam on our way to Berlin (2 pills each), and went to one of the raves for a night of partying. We each took half a pill and took a whole pill around 1 hour later.
We began pouring our hearts out to each other. I told her I was still in love with her, but that I had done some things that were wrong and wanted to come clean. She admitted the same and that she had cheated too. We talked about it for hours and tried to come to terms with why things had gone sour. We made no plans for the future regarding getting back together, but we made a pact that from then on, we would always be honest with each other.
We finished our trip and got engaged 4 months later. We have now been married for 2 1/2 years. We take E once a year or even less just for fun.
I'm not saying that E helps you find the one who's right for you, I'm just saying that we never would have worked things out if we hadn't been able to be completely honest with each other. In some ways I'm ashamed that I couldn't have been more honest on my own, but I was younger then. I'm a happier person because I practice honesty all the time now. I can't exactly praise E for making me honest, it just openned the door. Since then, it has been my job to live an honest and loyal life. It's a great way to live.

Rugby: England, South Africa tactics for World Cup final
TOKYO: Expected tactics of England and South Africa in Saturday's (Nov 2) Rugby World Cup final at Yokohama International Stadium:
ENGLAND
Speed, pace, urgency, quickness of thought and deed, and selectivity in when to engage in the physical battle.
England had all of that from start to finish against New Zealand and they will need it again, perhaps even more so, to knock South Africa out of their stride in the final.
England's speed of recycling, a result of Tom Curry, Sam Underhill, Maro Itoje and Co sprinting into rucks, meant New Zealand's defence always seemed to be scrambling by the time twin playmakers George Ford and Owen Farrell were fizzing passes left and right.
England's try after 97 seconds saw half a dozen examples of quick ball, rugby's holy grail, but the sweeping move retained its pace because the likes of hooker Jamie George and prop Kyle Sinckler did not slow it down when they got involved.
England will want more of that for 80 minutes on Saturday, working the big South African side back and forth again and again hoping to run the legs off them and then penetrate the gaps when they appear.
The contrast with how South Africa played against Wales in their semi-final was extraordinary - the Springboks were never in a hurry to go anywhere.
England will try to disrupt that by making a nuisance of themselves at rucks, but they will be selective, knowing that they could waste precious energy trying to shift some enormous Springboks forwards for often no real benefit.

Wingers Jonny May and Anthony Watson have shown themselves brave and effective jumpers, while fullback Elliot Daly knows this is the day when he will have to prove the doubters wrong over that aspect of his game.
George Ford will also be bracing himself for the most important defensive test of his career. Having seen how South Africa successfully targeted the channel of Wales flyhalf Dan Biggar, Ford knows what is coming.
Coach Eddie Jones has backed him to stand his ground, however, resisting any temptation to return to the meatier midfield option he went for in the quarter-final with Owen Farrell at 10.
SOUTH AFRICA
The Springboks have pretty much reverted to what has worked for them for decades, and though they may have the odd trick up their sleeves for the final, the selection of six forwards on the bench is an indicator of how they will approach the game.
It is a simple, proven game plan and when executed well, even against teams fully primed for it, one that can be difficult to combat as Wales found in the semi-final.
Orchestrating the system are flyhalf Handre Pollard and scrumhalf Faf de Klerk, a bundle of energy who can also make rugby time stand still when poised at the back of an immovable ruck waiting to send yet another kick high into the sky.
Then the pace of outside backs Willie le Roux, Makazole Mapimpi and the hyper-dangerous Cheslin Kolbe give chase to put receivers under pressure.
Centres Lukhanyo Am and Damian de Allende are more from the "through rather than around" school of centres but Springboks' hopes of victory probably depend more on Pollard kicking penalties than his fellow backs running in tries.

Exploiting Yum and DNF Plugins for Persistence
Two Metasploit Framework modules have held my interest in the last few weeks: the ones for persistence using Linux package managers apt and Yum. While they require root privileges to exploit, they provide a novel persistence mechanism that is likely overlooked by defenders. While looking at these modules I noticed that persistence using DNF wasn’t included, and I set off to find a way to persist on Linux systems using DNF plugins.
What’s a Package Manager, anyway?
On Windows systems most folks download applications from sites on the Internet or install them from media such as CDs or DVDs. This proves to be a major threat to the stability and security of Windows as it lets users download and install unpredictable software. On the other side of the spectrum, it allows users to find and use software to improve their world.
For Linux distributions, the software installation model looks different. You can still download software from the Internet, but it is not usually distributed in binary form for Linux systems. In these cases, you’d need to download the source code from a trusted mirror, compile it, and resolve any dependencies needed to make the software work. This is unfriendly for inexperienced users and can cause misconfiguration. As systems developed, a more friendly form of software distribution evolved: packages. Packages became an easy way to distribute compiled binaries for specific Linux distro versions and the software that managed packages helped administrators automate dependency resolution and configuration.
Now, most Linux distributions have a package manager and consume one of a few package types. The most common are RPM Package Manager (RPM) and Debian (DEB) packages. RPM packages work with systems that derive from Red Hat Enterprise Linux. These include RHEL itself, CentOS, and Fedora. DEB packages work with systems that derive from Debian Linux. These include Debian, Ubuntu, Mint, ElementaryOS, and others.
On the RPM side, administrators used the Yum command to interact with packages prior to RHEL/CentOS 8 and Fedora 22. After those builds, administrators began to use the dnf command. On the DEB side, administrators typically use the apt or apt-get commands to interact with packages. As these package managers became more complex, they included plugins or additional functionality to make package installation more extensible. A good example of this in Yum is the fastestmirror plugin that measures the speed of interaction with one or more update mirrors and helps Yum pick the fastest one.
For the rest of this post we will focus on Yum and DNF plugins. Some of this functionality also exists in apt, but that’s a story for another day.
Foundational Yum and DNF Plugin Knowledge
Yum and DNF are both written in Python and handle all the operations around package installation. From the terminal you’ll run commands such as this:
/usr/bin/dnf install httpd
/usr/bin/yum update
Since these tools are implemented in Python, their plugins are also Python.
Yum
With Yum, we need a few things for plugin execution. First, plugins must be enabled in /etc/yum.conf
. This is done with the line plugins=1
. Next, one or more plugin configurations present in the /etc/yum/pluginconf.d
directory must be enabled with a line enabled=1
. Finally, the Python plugin code itself lives in the /usr/lib/yum-plugins
directory. When writing the plugin, the developer can set hook functions that will execute when Yum executes specific triggers.
As it so happens, the fastestmirror
plugin is always used by yum in its default state. An easy way to exploit this is to plant malicious code within /usr/lib/yum-plugins/fastestmirror.py
. This requires root privileges and will cause the malicious code to run as root every time Yum executes for installations or updates.
DNF
With DNF, the configuration and code paths change but most of the concepts stay the same. First, DNF configurations exist in /etc/dnf/dnf.conf
. Plugins are enabled by default and are only disabled if a line similar to plugins=False
is present. Next, plugin configurations exist in the /etc/dnf/plugins
directory. Finally, the actual plugin code lives under the /usr/lib/python3.6/site-packages/dnf-plugins
directory, but the path will change as Python versions change.
In DNF, we can target one specific plugin for persistence: generate_completion_cache.py
. This plugin executes whenever an administrator runs dnf install
or dnf update
to speed up shell completion. It is distributed by default across Fedora, CentOS, and RHEL distributions. There doesn’t appear to be a specific configuration file that disables the plugin itself. Even in the dnf-plugins-core documentation, the plugin appears intended to always run in the background without user interaction. This is perfect for exploitation. To show, we can use vim to change the plugin code.
Change /usr/lib/python3.6/site-packages/dnf-plugins/generate_completion_cache.py
to add the following code above import os.path
:
import os
os.system(‘touch /etc/root-marker’)
This will give us proof that the plugin executed as root and wrote a file to disk.
Next, execute these commands (as root):
dnf update
ls -l /etc/root-marker
If /etc/root-marker
exists, you have a successful execution.
Detection and Breakage
I haven’t dived too far into detection for this technique. Process monitoring will show the code you add as spawning from an instance of python
with the command line showing dnf update
or a similar command. You may find luck monitoring for different exec
system calls that spawn shell processes, scripts, or other utilities. Any Python code you add that does not spawn an external command will execute within the dnf
python instance itself. This will blend in with surrounding update activity.
This technique will probably break with package updates to dnf-plugins-core
. In addition, you can revert the plugin file by reverting the added code.
Why not just change DNF itself?
You can probably do that, I just zoomed in on the plugins for execution. If you want to modify DNF for persistence, you probably can.
Is it useful?
It depends. This technique requires root/sudo privileges to use. The technique assumes you’re attempting to persist on a system that you’ve found either misconfigured or susceptible to privilege escalation. This path should not be your first stop for persistence if you only have user privileges.

After you have initialized a FooTable, you might need to "reset" it. One reason could be that you are changing the columns in the table after an AJAX call. In this case you would need to call the reset method of FooTable:
$('.footable').data('footable').reset();
In this demo, I reset the FooTable, then add a column onto the table structure, and then initialize FooTable again afterwards:
$('.reset').click(function (e) { e.preventDefault(); extraCols++; $('table').data('footable').reset(); //Add a new column into the table header $('table thead tr').append('
Column ' + extraCols + '	'); //add data into the table for the new column $('table tbody tr').each(function(i) { $(this).append(''+ extraCols + '.' + i +'	'); }); //fix the colspan of the footer to cater for the new column $('table tfoot tr td').attr('colspan', 5+extraCols); $('table').footable(); });

How to download and install
InterProlog installation does not require a compilation, as it can be
installed by copying a directory and editing one file; but the Prolog system(s)
to use may need to be compiled, namely under Unix. InterProlog is compatible with Windows XP/2000, Mac OS X and Linux. It requires Java 1.4 and
either XSB Prolog 2.7.x, SWI 5.4.x or YAP 5.x.
Please follow the steps below for your system:
Step
|
Comments
|
Windows 2000, XP
|
Mandrake Linux 10.2, Mac OS X
|
1
|
The Java Runtime Environment will be sufficient if you don't plan to
write any Java code AND you're using Windows. Otherwise you need the
Java
Development Kit |
Download J2SE from java.sun.com site (preferably
version 1.4 or later), http://java.sun.com/j2se/1.4.2/download.html,
and install it some directory MY_JAVA_DIR in your disk
|
| See if it works in a command shell window, by typing
MY_JAVA_DIR\bin\java
-version |
See if it works in a command shell window, by typing
MY_JAVA_DIR/bin/java
-version |
|
You should obtain something like this:
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)
|
| Write down (or copy into the clipboard...) the path
MY_JAVA_DIR.....bin,
the directory where the java executable is. We'll use this below to define
the JAVA_BIN environment variable |
| |
2
YAP
|
You need to install either XSB Prolog or/and SWI Prolog or/and
YAP Prolog |
To get and install XSB Prolog
2.7.1 with
built-in InterProlog support (interfacing through both sockets and JNI) follow these
instructions. XSB Prolog 2.6 is no longer supported, fall back to
InterProlog 2.1.1 if you must use it. To get and install SWI Prolog (interfacing through sockets, no
JNI) just install the
standard version (5.4.6 or later); if you're building it yourself make
sure you make and install clib . To get and install YAP Prolog (interfacing through sockets, no
JNI) just install the standard version (5.0 or later) |
|
Write down (or copy into the clipboard...) the paths for the
directories containing the executable images of Prolog. We'll use this below to define the XSB_BIN_DIRECTORY, SWI_BIN_DIRECTORY
and YAP_BIN_DIRECTORY environment variables (or just one of them if
you only need one Prolog).
These will typically be something like
|
|
XSB_DIR...config.....bin
SWI_DIR...bin
\Program Files\Yap\bin
|
XSB_DIR...config.....bin
/usr/lib/SWI_DIR/bin/i686-linux
For Yap, /usr/bin
|
| |
3
|
InterProlog is installed by copying a file tree and
editing some environment variables in a text file |
Download the InterProlog zip file from
here,
which includes this page, and expand it into somewhere in your disk |
|
Look into the windowsScripts directory. Edit windowsVariables.bat, changing the variables JAVA_BIN,
XSB_BIN_DIRECTORY and/or SWI_BIN_DIRECTORY and/or YAP_BIN_DIRECTORY
to the values you got in the install steps
above
|
Look into the unixScripts directory. Edit
unixVariables.sh, changing the variables JAVA_BIN,
XSB_BIN_DIRECTORY and/or SWI_BIN_DIRECTORY and/or YAP_BIN_DIRECTORY
to the values you got in the install steps
above
Mac OS X note: uses some different system directory arrangements take a look at
MacOSXVariables.sh for inspiration
Make sure the script files are executable:
chmod a+x *.sh
|
|
That's it :-)
See if it works by running a run....listener.bat scripts (./run...listener.sh in Unix). A Java window with a Prolog listener should
appear, looking perhaps like this:
Alternatively, if you're using XSB Prolog you can try the
Sudoku puzzle editor/solver (change directory separators to / under Unix)
%JAVA_BIN%\java -DXSB_BIN_DIRECTORY=%XSB_BIN_DIRECTORY%
-classpath ..\interprolog.jar
com.declarativa.interprolog.examples.SudokuWindow
See the sources in com/declarativa/interprolog/examples for more
information; subdirectory SudokuPuzzles contains... puzzles, in a simple
Prolog format.
If you installed ALL Prologs supported by InterProlog (currently
XSB, SWI and YAP), you can optionally run the standard test suite, using
the script testit ; when finished successfully (after about a
couple of minutes in a 400MHz Pentium) the following window will appear:
If things don't go well: first make sure the steps above were done
properly; then open a command shell window, cd to the interprolog212
directly, run the failing script with -debug afterwards, and email the console log to
<EMAIL_ADDRESS>For
example, to make runSWISPlistener.bat report debugging information edit
the command line to
%JAVA_BIN%\java -classpath %CLASSPATH%;..\interprolog.jar com.declarativa.interprolog.gui.SWISubprocessEngineWindow
-debug

Using it
|
For Prolog development, use
runXXXSPListener, which acts as a
simple graphical front-end to the full Prolog system through a
SubprocessEngine (using sockets), allowing you to get
multiple solutions, Prolog textual I/O etc. runNativeListener uses
the JNI interface (currently available only for XSB Prolog), which lacks
the traditional top level Try some Prolog goals, such as browseTerm(vp(np(interprolog),verb(working))),
which should display a tree. You may drag your Prolog source files into the listener
window for consulting, or use the menu "File/Consult" . Edit the files with you favorite editor.
Some documentation:
- Java: Tutorial,
Reference
(your JDK installation may include this)
- Prolog:
- InterProlog: introductory paper,
Java-side API,
Prolog-side predicates, FAQ.

Improvements over version 2.1.1
- Support for YAP Prolog
- Additional program example: a graphical Sudoku puzzle editor and solver
- PrologEngine is now an interface, for the sake of flexibility; most of the old PrologEngine functionality moved into the new AbstractPrologEngine class,
courtesy of Chris Rued at XSB Inc
- Several bug fixes, mostly courtesy of Tanya Vidrevich and Chris Rued at XSB Inc.
- Additional control creating (XSB) NativeEngines, by specifying Prolog startup arguments in the constructor
- New method PrologEngine.getPrologNumericVersion, useful for scenarios depending on the functionality of specific Prolog versions
- InterProlog threads now properly killed on PrologEngine.shutdown()
- Minor changes to the console listener scripts, extra test cases
Improvements over version 2.03
- Multiple PROLOG support: XSB Prolog and SWI Prolog
SubprocessEngine is now an abstract class, to accomodate the support of multiple Prolog implementations. The "old" SubprocessEngine is now
XSBSubprocessEngine
- The interprolog.P is gone from com/declarativa/interprolog; each Prolog implementation has its specific file in this directory, typically in a subdirectory, currently
xsb/interprolog.P and swi/interprolog.pl; most of the specific Prolog dependencies are in these files and in PrologImplementationPeer subclasses
- New method
toString(PrologEngine engine) in class TermModel, uses the standard startup (not necessarily current) operator definitions for the engine, rather than the common (engine) subset.
- Functional and other improvements
PrologEngine.consultAbsolute(File) : consults a Prolog file from an absolute path
Another variant of the deterministicGoal method: TermModel deterministicGoal(TermModel G), useful for inter-Prolog goal calling. For example, the following goal (running in any supported Prolog, say
XSB) instantiates a SWI engine and obtains a goal solution for goal G:
javaMessage('com.declarativa.interprolog.SWISubprocessEngine',SWI,'SWISubprocessEngine'),
buildTermModel(G,GM), javaMessage(SWI,SM,deterministicGoal(GM)),
recoverTermModel(SM,Solution), javaMessage(SWI,shutdown).
- More robust PrologEngine.interrupt() handling, by using Prolog throw/catch
- Improved InterProlog debugging information for SubprocessEngines created with the debug
argument true: they now print to System.err ALL Prolog output during startup
- Runtime environment configuration
- Zero-argument Prolog engine constructors, for easier use in some contexts. For a PrologEngine to be instantiated without a constructor argument, a property must be defined in either file
interprolog.defs (a Properties file in the format described in
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Properties.html
, in the directory where the jar file containing the InterProlog classes is) or in the global properties (by using the -D java switch). The properties should include XSB_BIN_DIRECTORY and/or
SWI_BIN_DIRECTORY, depending on which Prolog(s) you're using
NativeEngine now requires as argument (either explicitly or implicitly through the above Properties mechanism) the path to the XSB binary directory as the constructor argument, rather than the base directory as before, to simplify configuration; notice that this has more information than the base directory, eg for XSB it embbeds the consequence of being in a certain operating system.
- Extra optional constructor argument in
PrologEngine and subclasses,
loadFromJar. InterProlog startup files can now be loaded either from the jar file (as before) or from
classname-relative locations in the file system: interprolog.P from
...com/declarativa/interprolog/{xsb or swi} and visualization.P from
...com/declarativa/interprolog/gui/ . Loading from the file system can be useful while fiddling with InterProlog itself and testing changes to these files. There's a simple command line argument
("-nojar") that can be used in listener invocation scripts, see
ListenerWindow.commonMain().
Known limitations:
Use at your own risk; bug reports welcome except for the following.
- Object grammar does not support conversion of Java doubles and longs to
Prolog numbers, but it recognizes and
generates them
- See comments in streamcontents/4 in com/declarativa/interprolog/interprolog.P for some limitations
on serialization of complex (e.g. AWT) objects
- Changing the Prolog top level prompt handler would break communication with
Java
- The javaMessage predicate performs no coercion of basic type arguments
(e.g., if a formal parameter is
long then an actual parameter
with int is not acceptable), only of object
types (e.g. the actual parameter can be a subclass of the formal parameter).
- YAPSubprocessEngine does not support interrupt() under Windows
- NativeEngine (XSB) not working on Windows 2000
- Cannot use floats on XSB Prolog on Mandrake Linux 10.2, cf. reported bug
(but they wok fine on Mac OS X)

you must still call UseStaticFiles as well. This is because UseDefaultFiles is a URL re-writer that doesn’t actually serve the file. You must still specify middleware (UseStaticFiles, in this case) to serve the file.

app.UseFileServer();
// Enables all static file middleware (serving of static files, default files, and directory browsing).
app.UseFileServer(enableDirectoryBrowsing: true);

FileExtensionContentTypeProviderThis class contains an internal collection that maps file extensions to MIME content types. To specify custom content types, simply instantiate a FileExtensionContentTypeProvider object and add a mapping to the FileExtensionContentTypeProvider.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
...
// Allow directory browsing.
app.UseDirectoryBrowser();
// Set up custom content types - associating file extension to MIME type
var provider = new FileExtensionContentTypeProvider();
provider.Mappings.Add(".myapp", "application/x-msdownload");
// Serve static files.
app.UseStaticFiles(new StaticFileOptions { ContentTypeProvider = provider });

What is Elements?
Elements is a cross-platform library for creating building elements. It's meant to be used by architects, engineers, and other building professionals who want to write code that generates buildings.
When we started Hypar we needed a library that would generate building elements and run at the core of each function on the platform. Because we don't like rebuilding the wheel, we looked around for existing libraries that fulfilled the following requirements:
- The library must be small and fast. Elements is currently ~300kb and we're working every day to make it smaller.
- The library must run in micro-services on Linux.
- The library must have great visual documentation. If we're going to pass this library on as a recommendation to developers on Hypar, we want great docs.
- The library must be free of dependencies on host applications like Rhino or Revit or geometry kernels like Open Cascade which, while really cool, become a black box in your system.
- The library must be able to serialize data to formats like JSON, IFC,and glTF, that are useful to architects, engineers, contractors, and people building real-time visualization applications for AEC.
- The library must be written in a language that supports developer productivity through things like type safety, and which supports code re-use in other popular AEC applications like Dynamo, Grasshopper, Revit, and Unity.
We couldn't find anything quite right. So we started building this.
Where Can I Get Elements?
If you want to use Hypar in your .NET project, it's available as a NuGet package. It can be installed like this:
dotnet add package Hypar.Elements --version 0.3.3
Elements is also open source. The code is available in the github repository.
Where Can I Use Elements?
Elements will work in any project that supports the .NET Standard 2.0 API set. This includes Revit Addins (including Dynamo), Rhino addins (including Grasshopper), Unity games, and more! You can find out about more about .NET Standard API coverage here.
Code you write with Elements is just code, you are free to use it wherever it is compatible. One place we recommend is Hypar
Where Can I Get Some Code Examples?
The Elements library API documentation is located here.
Does Elements Create Geometry?
Elements contains a very simple geometry library full of classes like Vector3
, Line
, Polygon
, and Arc
. It contains boundary representation(BREP) classes with methods for creating extrusions and sweeps, a Mesh
class for stuff like topographies that don't represent well using BREPs, and classes for working with GeoJSON. We like to joke that Elements' geometry library does "flat stuff with holes in it" really well.
I'd Like a Feature or Something is Broken
All conversations about Elements happen on the github repository. Please open a new issue there to start a discussion.

NTP Pool DNS servers
To direct our millions of NTP users to an appropriate server we run a
customized DNS server. Many of the instances are offered by
volunteers around the world. This page provides more information if
you are interested in providing a (virtual) server to be used for DNS
services.
Requirements for hosting a server
The NTP Pool DNS server usually runs on CentOS or Ubuntu LTS; either
will work though Ubuntu LTS is preferred. We also have one instance
running on FreeBSD (in a jail I believe) which is performing very very well,
but our automation setup isn't as robust for configuring it.
If it's a virtual machine it needs to be something like KVM or BHyve
based, not a "kernel container based" system (basically our setup
process needs full root access to a kernel).
- Operating System
-
Basically just a minimal-ish install of (64-bit, x86_64) CentOS or
Ubuntu LTS. Our software also works with FreeBSD, but we
prefer not maintaining the base system on other operating
systems than Ubunutu and CentOS, so if the system runs FreeBSD
we prefer just getting a jail on a well maintained system.
- CPU
- Almost any two core 64-bit CPU from the last 4-5 years will do a nice job
- RAM
- Minimum 1GB, ideally 2-4GB to ease system maintenance tasks.
- Disk space
-
6-8GB or more, again mostly to allow for system updates etc. It
can be just about as slow as you can imagine and it'll be
fine.
- IP addresses
-
One routable IPv4 address, ideally also IPv6. If your
network supports us announcing our anycast network then we like doing that,
see below for BGP information.
- Bandwidth
-
It used to be less, currently it's about 5-10Mbit/second per server (anywhere
from 1-2TB data per month).
During certain times of the hour and the day the rate goes up significantly
for a few seconds. If you are in a country with poor DNS server coverage
but can't serve that many requests, we have tools to give you less traffic.
- Software
-
Regular DNS servers can't smartly respond with a "nearby" server out of
several thousand and do so weighted, so we run a bit of
quirky DNS software that can.
- Firewall/security
-
No external firewall is needed, but in case you operate one:
- port 53 (UDP and TCP)
- port 22 (ssh)
- port 8052 and 8053 (mTLS authenticated monitoring)
- port 179 (for optional bgp setups)
Be sure to disable session tracking for port 53/udp if you do have a firewall.
- Management
-
We typically do the day-to-day management of the system.

Abstract
This document introduces the developer of geometric libreries and applications to the integrated development environment (IDE) set up for documentation and multilanguage development using LAR-CC, the Linear Algebraic Representation for geometry, manufacturing and physics with Chains and CoChains. This IDE is strongly based on the literate programming tool Nuweb, aiming at embedding the code in the documentation, and not vice-versa. The main goal of this framework is to facilitate how to express the why of software design decisions, and not only the tricky details of low level coding. I would recommend writing programs as if they were research papers and treat the code as you would write mathematical expressions in a research paper. Using multiple programming languages is allowed and even encouraged in larcc. When possible, the same functions coded in different languages should stay close within the same document subsection. The larcc IDE integrates a few programming, documentation and version control tools, including LATEX, Nuweb, Pandoc, and Git.

50 Cent Reveals Truth Behind His Instagram Page Getting Deleted: “You Can’t Just Make Some S**t Up”
by Angie DareNew York rapper 50 Cent is keeping it 100. The hip-hop veteran has come forward to address his Instagram page suddenly getting deleted.

A few days ago, 50’s IG page disappeared and appeared to get deleted.
There’s is nothing 50 Cent loves more than trolling every person he can on Instagram. But the hip hop star is having to find a new hobby these days because Instagram has suspended his account It was first noticed on Thursday afternoon that the Power producer’s account was no longer available on the platform. And it’s still a no-show nearly 24 hours later. (Metro UK)
Earlier this month, 50 apologized to “Power” actress Naturi Naughton for doing the most to her on IG.
Fif initially went online with a meme inspired from Tasha St. Patrick and James “Ghost” St. Patrick getting into a physical dispute.


Mothers of Russian prisoners demand justice from Putin
MOSCOW: Mothers of Russian prisoners denounced the prosecution of dissenters as a "travesty of justice" as they gathered outside the offices of the presidential administration on Tuesday (Nov 19).
Members of a new campaigning group, Mothers against Political Repression, appealed to President Vladimir Putin to intervene in an open letter read out to journalists.
The informal movement, the first of its kind, brings together families of protesters accused of violence against police, suspected extremists and others.
They called on Putin to have the courts, investigators and the FSB security service probed over their handling of the cases.
"The travesty of justice and lawlessness that are being perpetrated in front of the whole country undermine people's trust in the justice system and the state," the letter signed by 16 people said.
"In our view this negatively affects our country's stability and prosperity and leads to public discord," it added.
One woman at the gathering cried as others tried to console her.
Mothers Against Political Repression was set up last month in response to a police crackdown on the opposition to campaign on behalf of those convicted or detained.
One member of the movement, rights activist Alexandra Krylenkova, described their message to Putin as a "letter of despair".
"So many of these cases have resulted in monstrous sentences," she told AFP.
Galina Martintsova, whose 26-year-old son Maksim faces up to five years in prison for alleged violence against police, said the letter was their "last hope".
"It's clear that these are trumped-up cases," she said, praising the group for helping her to get through the ordeal.
"It's hard to fight against injustice when you are alone," she told AFP.
Tens of thousands of people rallied in Moscow this past summer after allies of opposition leader Alexei Navalny were barred from standing for seats in city parliament in the September elections.
The authorities unleashed a major crackdown, arresting hundreds and jailing several people.
Several groups, from priests to teachers, have also signed open letters in support of the victims of what they argue was a disproportionate and arbitrary clampdown.

Sharding-JDBC supports the paging query of MySQL, PostgreSQL and Oracle. For SQLServer, due to its complex paging query, only partial queries can be executed.
The SQLs with excessive paging offset can result in the poor performance of the database. Take MySQL for example:
SELECT * FROM t_order ORDER BY id LIMIT 1000000, 10
This SQL makes MySQL to retrieve 10 records after skipping over 1000000 records, if no suitable index can be used. In the case of Sharding (assuming two databases for sharding), in order to ensure the result are correct, the SQL will be rewritten as:
SELECT * FROM t_order ORDER BY id LIMIT 0, 1000010
The records before the offset are taken out, and only the last 10 of all the records ordered are obtained. If the database itself is stressed, the SQL will further exacerbate the performance bottleneck, for the original SQL only needs to send 10 records to the client, but the rewritten SQL will send 1000010*2 to the client.
Two of aspects is optimized in Sharding-JDBC. First, Sharding-JDBC uses streaming + merge sort to avoid excessive memory consumption. Sharding-JDBC uses the rewrote SQLs for the query, and necessarily takes up additional bandwidth, but does not cause the memory a sharp rise. Most of people think that Sharding-JDBC will load 1000010*2 records into memory, which will take up a lot of memory and cause a memory leak. However, because the records of each result set are ordered, sharding-jdbc only compares the current record of each sharding at a time, and only saves the cursor of the current record in memory. The time complexity of merge sort is only O(n), and the loss of performance is very small.
Second, sharding-jdbc also optimizes queries that are only routed to a single slice. The query routing to a single slice can ensure the result are correct without the SQL rewriting. Therefore, Sharding-JDBC will save the bandwidth by means of not rewriting SQLs.
Since the LIMIT queries the data not using the index, a better solution is that you operate paging by using ID, if the ID is sequential:
SELECT * FROM t_order WHERE id > 100000 AND id <= 100010 ORDER BY id
Or you can query the next page of data by recording the ID of the last record of the last query:
SELECT * FROM t_order WHERE id > 100000 LIMIT 10
The paging for both Oracle and SQLServer need to be processed through subquery, and Sharding-JDBC supports paging-related subquery。
Sharding-JDBC supports to use rownum for paging:
SELECT * FROM (SELECT row_.*, rownum rownum_ FROM (SELECT o.order_id as order_id FROM t_order o JOIN t_order_item i ON o.order_id = i.order_id) row_ WHERE rownum <= ?) WHERE rownum > ?
At present, it does not supports rownum + BETWEEN for paging.
Sharding-JDBC supports TOP + ROW_NUMBER() OVER for paging:
SELECT * FROM (SELECT TOP (?) ROW_NUMBER() OVER (ORDER BY o.order_id DESC) AS rownum, * FROM t_order o) AS temp WHERE temp.rownum > ? ORDER BY temp.order_id
Sharding-JDBC also supports OFFSET FETCH in SQLServer 2012 or above for paging:
SELECT * FROM t_order o ORDER BY id OFFSET ? ROW FETCH NEXT ? ROWS ONLY
It does not support WITH xxx AS (SELECT …) or two TOP + subquery for paging. Because paging statements generated by Hibernate in SQLServer use the WITH statement, Sharding-JDBC currently does not support SQLServer paging based on Hibernate.
Both MySQL and PostgreSQL support LIMIT for paging, and subquery is not needed：
SELECT * FROM t_order o ORDER BY id LIMIT ? OFFSET ?
Sharding-JDBC also supports other subqueries similar with paging subquery. No matter how many layers in a subquery, Sharding-JDBC can always find the first subquery that contains the table data, once the sub-subquery containing table data is found in the lower nest, Sharding-JDBC will throw an exception.

Simply speaking, none-functional subqueries can be supported in most cases, such as pagination or statistics, etc, but subqueries for business is not supported currently.
In addition, subqueries containing aggregate functions are not supported currently due to merge constraints.


How to choose a chart
Before describing how to choose a chart first consider why we should use a chart at all. Charts employ our visual and spacial reasoning skills developed over a millennia to quickly isolate, synthesize, and then evaluate the environment around us. Charts therefore afford the viewer a tool to quickly understand data visually. Gary Klass describes the goal of charts this way:
A graphical chart provides a visual display of data that otherwise would be presented in a table; a table, one that would otherwise be presented in text. Ideally, a chart should convey ideas about the data that would not be readily apparent if they were displayed in a table or as text. -- Gary Klass
As Klass points out, charts are not about displaying data, they are about conveying ideas through data. Successful charts are succinct self-explanatory visual systems which answers a question about the comparison, composition, distribution or interrelationship of the data they present. What follows is a collection of charts divided among the kinds of questions they are well-suited to answer.
Comparison - When comparing and contrasting the difference in data over an interval period or between member of a group, a comparison chart is a fine choice. As with all charting choices restraint should be applied here too. For example if you are comparing year to date totals of your sales force, a sortable table can take up less visual space and be more useful than a multi-series bar chart.
Comparison charts work best when visual scale of data values are hard to understand textually. Revisiting our previous example, imagine one salesperson has noticeably outperformed their peers. This difference may only add a couple of zeros to a table column, which may be hard to appreciate by just casually scanning the document. However when the totals are mapped visually the comparison can be quite expressive.
Comparison charts also work well when showing the change in values over time. This is why line charts are commonly used to show the ebb and flow of a company's stock price. The following charts work well when the comparison of data values is the goal:
| Column chart | d4 | elsewhere |
| Bar chart | d4 | elsewhere |
| Table | d4 | elsewhere |
| Radar chart | d4 | elsewhere |
| Line chart | d4 | elsewhere |
| Bullet chart | d4 | elsewhere |
| Small multiples | d4 | elsewhere |
| Heatmap chart | d4 | elsewhere |
Composition - When the story behind your data includes the cumulative total of the various series along with the series themselves a composition chart may be the right choice. Composition charts allow you to isolate individual series but visually link them to a larger whole. The following charts works well for answering questions about composition:
| Stacked column | d4 | elsewhere |
| Stacked area chart | d4 | elsewhere |
| Waterfall chart | d4 | elsewhere |
| Donut chart | d4 | elsewhere |
Distribution - Distribution charts are used when the question you want to answer relates to how data is spread out across a field of values or when you want to show a correlation between two variables.
| Column histogram | d4 | elsewhere |
| Line Histogram | d4 | elsewhere |
| Scatter plot | d4 | elsewhere |
Relationship - When answering a question about the relationship between values, be it hierarchy, or similarity you are trying to explain the relationship. Relationship charts are good for displaying large numbers of data points without being constrained by a time axis. Relationship charts are good at highlighting similarities between data values rather than difference. Relationship charts are also often used when displaying large numbers of values which may differ by orders of magnitude.
| Scatter plot | d4 | elsewhere |
| Sunburst chart | d4 | elsewhere |
| Treemaps | d4 | elsewhere |
| Bubble chart | d4 | elsewhere |
If you are struggling to determine what chart to use this pdf document as a method to kick start a thought experiment.
Features of a D3 chart
Part of D3's flexibility is because it aims to be a grammar for creating data driven visuals; therefore charts are merely a subset of D3's total vocabulary. D3
Data symbols - A chart is a graphical representation of data. The data is described through the use of visual symbols. In some cases they can be geometric shapes like circles, or rectangles, and at other times they can be lines, which connect to points.
Borders - Borders visually separate the chart from the surrounding interface and should only be used if this separation would be unclear to the viewer.
Grid lines: - Are used as visual connectors to link visually separated elements together. Grid lines should be as light as possible, ideally the viewer should only become aware of them if they are looking for them.
Scales - Scales define the minimum and maximum values for a given dimension dataset. Typically scales are divided into regular increments along the axes.
Axes - The axes represents numerical coordinates across a plane. In charts the axes are unique markers of the cartesian coordinate system, and allow the viewer to correlate the position and size of data symbols within the chart field to specific values along the axes.
Text - Text values in D3 charts are typically used to annotate data symbols, or axis units. Text elements can also be used to give a fuller context to the chart when applied to titles, or footnotes. However, text should be minimized because charts are meant express information quickly and visually. The overuse of text should suggest to the designer that their chart is not as expressive as it could be. The most common uses of text in D3 charts are:
Title - Depending on your audience titles can either persuade the viewer towards a particular conclusion or simply describe the data series.
Axis titles - Axis titles should only be used if they provide important information what would not otherwise be ascertained by reading the title or axis labels.
Data Labels - These labels annotate data symbols with information which would otherwise be hard to visually correlate quickly. That said, data labels can add visual noise to the interface when overused and should only be employed if they enhance the readability of the chart.
Legends - Legends describe the various series in a multi-series chart. Therefore they should only be used when displaying more than one data series.
Annotations - Annotations are notes, source references, or other textual caveats that help explain an aspect of the chart that cannot be represented visually.
Transitions (TODO)
Layouts (TODO)
Data - D3 accepts data in a variety of formats, which can frame the kind of chart that is chosen.
An array of numbers:
var numbers = [4, 5, 18, 23, 42];
Or an array of objects:
var letters = [
{name: "A", frequency: 0.08167},
{name: "B", frequency: 0.01492},
{name: "C", frequency: 0.02780},
{name: "D", frequency: 0.04253},
{name: "E", frequency: 0.12702}
];
Even an array of arrays:
var matrix = [
[ 0, 1, 2, 3],
[ 4, 5, 6, 7],
[ 8, 9, 10, 11],
[12, 13, 14, 15]
];

Govt yet to decide on steps to deal with plight of women migrants in Saudi Arabia
by bdnews24.comForeign Minister AK Abdul Momen has said that the government is yet to decide on a course of action to deal with the plight of Bangladeshi women workers in Saudi Arabia.
“We don’t know yet,” he said in response to a question on the matter at a press briefing on Thursday.
Over 270,000 women workers are working in Saudi Arabia, the minister said. Of them, 8,000 returned home while 53 have died.
On whether Bangladesh will stop sending women to work in the Middle-Eastern country, Momen said, “We can say almost 99 percent of the women are doing well and sending money back home.”
“But many will lose this opportunity if we stop.”
Recently, reports of Bangladeshi women being raped and impregnated in the Arab kingdom have caused a stir.
Momen said a shelter for women has been opened in Saudi Arabia where they can come in and voice their grievances.
“But we don’t get many complaints. If we recieve any complaints, then we can take up the matter with the Saudi government. Saudi government is very quick to take action,” he said.
“We don’t know the reason why they don’t complain to us in Saudi Arabia… may be out of fear or for other reasons,” he said, adding that the government has also opened a 24-hour hotline for vulnerable women.
Momen said he also asked the recruiting agencies to register women workers they send to Saudi Arabia as domestic help. “It would then make it easier for us to track them when they need any help.”

I enjoy the various forms of graphic design, anything from logo design to magazine spreads.
I greatly enjoy digital illustration, but am not afraid to work with physical mediums.
Growing up I had always been interested in art, and dabbled with various forms over the years, mostly drawing.
By high school, I had begun to take art as a career more seriously, and learned to use tools like Photoshop and Blender.
When I started college, I wasn't sure which form of art I wanted to specialize in, but the classes I took at Messiah helped shape me into who I am today.
Presently, I have learned that I don't want to focus on just one thing, so I've decided to keep my options open and work with whatever I enjoy most.

There might be times that you need to execute MongoDB commands via command line. One of the obvious reason for this is latency -- unlike hitting the MongoDB server across the network, executing the commands via shell is way very fast, specially if you are retrieving/processing huge amount of data.
Fortunately, MongoDB supports Server Side scripting, using JavaScript as programming language. It is as easy as creating a .js file in your server. In this tutorial, lets create a create_record.js file that will do the following tasks:
TO execute the file:
This will connect to localhost, in port 27017. Selecting the database "db1", then executing the create_record.js file.
That is how simple how to execute a JavaScript file in the server-side!

I'm A Celeb's Adele Roberts reveals guilt over explosive rows with Jade Goody on Big Brother
She was on the reality show in 2002
by Richard BellBBC Radio 1 DJ Adele Roberts, one of the famous faces due to feature on the new series of I'm A Celebrity... Get Me Out Of Here!, has opened up about feeling like she "let herself down" during her stint on Big Brother.
Adele was one of the contestants on the reality show back in 2002, when she entered the house alongside late star Jade Goody.

The pair clashed a number of times on the programme, including one memorable argument that ensued after Jade discovered she had a "minging" verruca.
Famously, Jade almost walked from the Big Brother house after that row, although was eventually persuaded to stay.
As reported by the Mirror, Adele said she felt like she "carried a lot of guilt" over her behaviour on the show and admitted she "could have been a much nicer person".
She said: "Looking back, I carried a lot of guilt about the way I acted in Big Brother and I feel like I let myself down and I could have been a much nicer person.
"I just think I judged people when I shouldn't have, I should have tried to get to know them a bit more and I think I probably hurt people when I didn't realise when I was in there.
 I just let the game get to me and got too negative and I just won't do that again this time."
Jade Goody later stared in Celebrity Big Brother. She was diagnosed with cervical cancer in 2008 and lost her battle with the disease on March 22, 2009.
Elsewhere in the interview, Adele said that by appearing on I'm A Celeb, she would like to "show a better side" to herself by treating her campmates well and having a "positive experience".

The new series of I'm A Celeb gets underway this Sunday (17.11.19) at 9pm on ITV.
The full line up was announced this week, with famous faces including American star Caitlyn Jenner, former EastEnders actress Jacqueline Jossa and Girls Aloud singer Nadine Coyle among those joining Adele Down Under.

In the past 4 years of my life, many people who are just starting out in programming world have asked me some version of this question:
Which programming language should I focus on learning?
What technologies should I be learning, so that they prove helpful in my career?
To many of them I have said:
Don’t bother to fix yourself into a grove/niche just yet.
When you are just starting out, it is not very useful to just focus on one language/technology. It might even happen that that one thing which you start focusing on doesn’t interest you at all and you just get behind it because you think that it has better career-prospects. In that case your life would become terrible and since you are not interested in your learning, you won’t be producing your best output. Which in turn would cause you to be mediocre at-best.
Let me give my own example, my first foray into programming was during my 10th grade, it was a 10-day after-school crash-course in C programming. It was an utterly horrible experience for me. After those 10-days I swore to never learn programming. The next year in school it was a choice for me to select either Computer Science or Biology, I chose CS because Bio was worse for me. Near the end of high-school I had decidedly switched my career goal from becoming an aerospace engineer to becoming a programmer.
 I was also enthusiastic about picking one language and then mastering it to get a good job and build cool things. There was just one hurdle for me (it actually turned out to be a boon), I didn’t have anyone to ask which language to choose and similarly there wasn’t anyone advising me to choose one, as I did not have confidence in either my teachers’ or my seniors’ knowledge in those regards. So I started looking at different things.
I started with learning Java as I wanted to make GUIs. Let’s just say that it took around a whole semester to be able to get a chat program working on local-network. Then tried learning about Android development, but poor developer experience turned me away. Then after seeing a friend using Visual Studio’s Layout Editor, I decided to learn C# because it was easier to create GUIs in. For some weird reason, I picked-up Visual Basic. Got bored with it in less than a week. My journey with C# didn’t last long. as there came Python, with all its conciseness and no explicit data-types. I had no idea what I should build with them, I just wanted to learn “cool stuff”.
Except these, there were other periods too, like:
- 2 months of competitive algorithmic problem solving, because I wanted to win Google Code-Jam :sweat_smile:
- A month of learning SQL as I wanted to become “The DB Programmer”
- Quite a few months of tinkering with Arduino and IOT
But none of those were able to hold my interest for long. Then I got offered an internship as Android Developer from my neighbor in his new startup. I had nothing to lose and too much to gain so I joined it. That was the turning point of my life that finally fixed my interest in Android Development.
Today 4 years after the start of that internship, I am near completing my first year as a professional Android dev. If I hadn’t tried all those many things I never would have known how little do I like them.
So finally, before parting, this would be my only comment. Don’t worry too much about which technology or language or new hip-concept to focus on and build a career in. Keep an eye out and make sure to try everything that you find interesting. You pretty sure won’t be able to so easily try everything after you start working professionally, an you would have to learn to feel okay with that. My friend Nate Ebel has recently written a nice article on it.
That’s all folks
Those are my thoughts on picking a speciality very early on in your development career. You can contact me via contact me or tweet to me @varun_barad.

Expose VirtualMachineInstances as Services
Once the VirtualMachineInstance is started, in order to connect to a VirtualMachineInstance,
you can create a Service
object for a VirtualMachineInstance. Currently, three types
of service are supported: ClusterIP
, NodePort
and LoadBalancer
. The
default type is ClusterIP
.
Note: Labels on a VirtualMachineInstance are passed through to the pod, so simply add your labels for service creation to the VirtualMachineInstance. From there on it works like exposing any other k8s resource, by referencing these labels in a service.
Expose VirtualMachineInstance as a ClusterIP Service
Give a VirtualMachineInstance with the label special: key
:
apiVersion: kubevirt.io/v1alpha2
kind: VirtualMachineInstance
metadata:
name: vmi-ephemeral
labels:
special: key
spec:
domain:
devices:
disks:
- disk:
bus: virtio
name: registrydisk
volumeName: registryvolume
resources:
requests:
memory: 64M
volumes:
- name: registryvolume
registryDisk:
image: kubevirt/cirros-registry-disk-demo:latest
we can expose its SSH port (22) by creating a ClusterIP
service:
apiVersion: v1
kind: Service
metadata:
name: vmiservice
spec:
ports:
- port: 27017
protocol: TCP
targetPort: 22
selector:
special: key
type: ClusterIP
You just need to create this ClusterIP
service by using kubectl
:
$ kubectl create -f vmiservice.yaml
Alternatively, the VirtualMachineInstance could be exposed using the virtctl
command:
$ virtctl expose virtualmachineinstance vmi-ephemeral --name vmiservice --port 27017 --target-port 22
Notes:
- If
--target-port
is not set, it will be take the same value as--port
- The cluster IP is usually allocated automatically, but it may also be forced into a value using the
--cluster-ip
flag (assuming value is in the valid range and not taken)
Query the service object:
$ kubectl get service
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
vmiservice ClusterIP <IP_ADDRESS> <none> 27017/TCP 2m
You can connect to the VirtualMachineInstance by service IP and service port inside the cluster network:
$ ssh<EMAIL_ADDRESS>-p 27017
Expose VirtualMachineInstance as a NodePort Service
Expose the SSH port (22) of a VirtualMachineInstance running on KubeVirt by creating a
NodePort
service:
apiVersion: v1
kind: Service
metadata:
name: nodeport
spec:
externalTrafficPolicy: Cluster
ports:
- name: nodeport
nodePort: 30000
port: 27017
protocol: TCP
targetPort: 22
selector:
special: key
type: NodePort
You just need to create this NodePort
service by using kubectl
:
$ kubectl -f nodeport.yaml
Alternatively, the VirtualMachineInstance could be exposed using the virtctl
command:
$ virtctl expose virtualmachineinstance vmi-ephemeral --name nodeport --type NodePort --port 27017 --target-port 22 --node-port 30000
Notes:
- If
--node-port
is not set, its value will be allocated dynamically (in the range above 30000) - If the
--node-port
value is set, it must be unique across all services
The service can be listed by querying for the service objects:
$ kubectl get service
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
nodeport NodePort <IP_ADDRESS> <none> 27017:30000/TCP 5m
Connect to the VirtualMachineInstance by using a node IP and node port outside the cluster network:
$ ssh cirros@$NODE_IP -p 30000
Expose VirtualMachineInstance as a LoadBalancer Service
Expose the RDP port (3389) of a VirtualMachineInstance running on KubeVirt by creating
LoadBalancer
service. Here is an example:
apiVersion: v1
kind: Service
metadata:
name: lbsvc
spec:
externalTrafficPolicy: Cluster
ports:
- port: 27017
protocol: TCP
targetPort: 3389
selector:
speical: key
type: LoadBalancer
You could create this LoadBalancer
service by using kubectl
:
$ kubectl -f lbsvc.yaml
Alternatively, the VirtualMachineInstance could be exposed using the virtctl
command:
$ virtctl expose virtualmachineinstance vmi-ephemeral --name lbsvc --type LoadBalancer --port 27017 --target-port 3389
Note that the external IP of the service could be forced to a value using the --external-ip
flag (no validation is performed on this value).
The service can be listed by querying for the service objects:
$ kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
lbsvc LoadBalancer <IP_ADDRESS> <IP_ADDRESS>,<IP_ADDRESS> 27017:31829/TCP 5s
Use vinagre
client to connect your VirtualMachineInstance by using the public IP and
port.
Note that here the external port here (31829) was dynamically allocated.
