THCHS30 is an open Chinese speech database published by Center for Speech and Language Technology (CSLT) at Tsinghua University. The origional recording was conducted in 2002 by Dong Wang, supervised by Prof. Xiaoyan Zhu, at the Key State Lab of Intelligence and System, Department of Computer Science, Tsinghua Universeity, and the original name was 'TCMSD', standing for 'Tsinghua Continuous Mandarin Speech Database'. The publication after 13 years has been initiated by Dr. Dong Wang and was supported by Prof. Xiaoyan Zhu. We hope to provide a toy database for new researchers in the field of speech recognition. Therefore, the database is totally free to academic users. You can cite the data using the following BibTeX entry:

[gecode-users] New Gecode/J
Ujhelyi Zoltan
uz602 at hszk.bme.hu
Sun Jan 27 12:53:10 CET 2008
Hello,
at the Budapest University of Technology and Economics we are planning
to use Gecode/J for a new project. We are currently exploring it.
As we looked at the homepage, we saw that a new version of Gecode was
released in November, and I read in the gecode-users archive, that the
porting of Gecode/J has began.
I would like to know whether you suggest waiting for the new version
(or at least using the svn version), or is it better to start on with
Gecode 1.3.1 and Gecode/J 1.0.1? Some of the new Gecode features does
look promising, and the more efficient constraint solving comes always
in good stead.
Thank you very much for your help

WRF CHEM compilingInARM BeagleBoneBlack
2014-08-23
###WRF CHEM compiling in ARM architecture, Beagle Bone Black###
This is based on http://www2.mmm.ucar.edu/wrf/OnLineTutorial/index.php ####compiler test#### went successful, except in test4 using 64 bit ###libraries### ####Netcdf compiling#### 1. Environment has to be properly setup, following was correct for ARM arch, clarified based on this
export DIR=/media/card/wrf/lib
export CC=gcc
export CXX=g++
export FC=gfortran
export FCFLAGS=-g
export F77=gfortran
export FFLAGS=-g
export CXXFLAGS=-g
Faced error in
make
after configure command of./configure --prefix=$DIR/netcdf --disable-dap \ --disable-netcdf-4 --disable-shared
. The errors are like./libtool: line 1133: g++: command not found
,libtool: link: unsupported hardcode properties
( solved by sudo apt-get install g++-mingw-w64-i686), with blocking in folder CXXar: libnetcdf_c___la-netcdf.o: No such file or directory
(solved by specifying correct environment variables as above). Following packages were also forced to install by errors and for searches while making.sudo apt-get install g++-mingw-w64-i686 sudo apt-get install build-essential sudo apt-get install csh sudo apt-get install gfortran
After making the right environment, the command
make
finished without error and so themake install
, created a folder named netcdf and executables are in the folders. As per the page, environments were again made forexport PATH=$DIR/netcdf/bin:$PATH
andexport NETCDF=$DIR/netcdf
. Then the netcdf compiling test was made usingnc-config --version
andnc-config --prefix
, it given the correct answers.Following the reboot of BBB, all the created environment setup gets removed. It is returning blank line for
echo $DIR
. For instance, compiled the libraries in sd card of the BBB. The sd card is mounted to BBB using the commandsudo mount -t ext4 /dev/mmcblk0p2 /media/card
based on this. Then again all the environment set up is executed only nc-config worked properly, notably command likeexport DIR=/media/card/wrf/lib, export PATH=$DIR/netcdf/bin:$PATH, export NETCDF=$DIR/netcdf
####compiling mpich####Even if the ssh made broken with BBB, the environment set up gets removed. Needed to redo the export command as specified above. Compiled MPICH for parallel cluster execution as per the page .
There is an error saying
mpich type_get_attr.lo is not a valid libtool object
, whilemake
after configuring by executing the command./configure --prefix=$DIR/mpich
.Based on this latest libtool in Debian package was
dpkg -i
installed by removing the older version available with BBB.After this,
make
ended without any error and as well themake install
. An environment is set up for mpich byexport PATH=$DIR/mpich/bin:$PATH
. ####libraries for WPS: zlib,libpng,JasPer####These libraries were installed without any error as per the page
####Library Compatibility Tests#### 1. compatibility test such as Fortran + C + NetCDF and Fortran + C + NetCDF + MPI was carried out and it is executed without any error.
####compiling WRFV3.6####
1. As per the page, the source folder of WRFV3 was unzipped and cd into it and run ./configure
but ends with an empty list of the platform to choose, that way the configure script has to end with abruptly.
2. Based on this work of porting WRF for ARM, found that file configure_new.defaults
in arch folder of the source has to be edited to replace word x8664 with armv7l for gfortran compiler section. Note the word x8664 has to be replaced only along with gfortran. Otherwise, it will be problematic.
3. With this edit the problem of blank platform list was solved and now the ./configure
ends with a warning saying that W A R N I N G There are some Fortran 2003 features in WRF that your compiler does not recognize. Removed signaling call with the name IEEE and that may not be enough
. This was referred in this forum post indicating a minimal error due to compiler version. The current version of gfortran is 4.7 (from here)and BBB is having 4.6.3 version.
4. Downloaded the new version deb file of gfortran for armhf and dpkg on this deb gives rise to an error saying that gcc also an older version of 4.6.3. However, faced the problem in updating the gcc and gfortran, ended with an error saying the update was expired. The error was resolved using this command based on this page. To list installed pages in debian used dpkg-query -l
. After a failed attempt for installing gfortran 4.7 and gcc, it is felt to stick to the wrf compile by neglecting the latter warning as said in this page
5. wrf compile restarted after rectifying the earlier error of no installation of libcloog-ppl while compilation of WRF. In the current attempt, it was followed by the notes of this page for compiling WRF CHEM by adding environment in /etc/bash.bashrc file. This page is a reference of installing libcloog-ppl is used for solving the error.
6. This attempt of compiling wrf also has the problem of errors such as Fatal Error: Can't open module file 'module_configure.mod' for reading at (1): No such file or directory
, this error is continuousness for multiple modules. This common error is referred in this page indicating due to mismatch of compiler versions. An attempt is made with WRFV 3.4.1 and chem code as done for HP laptop also ending with this similar error. The attempt to compile WRF CHEM in BBB is abruptly ending here due to time constraints.
####Conclusion####
It can be concluded that WRF-CHEM most possibly would compile in ARM cores as noted here. The compilers version (gcc, gfrotran, cpp), version of WRF and Debian distribution will be the major bottleneck for that.
Based on 1. http://forums.debian.net/viewtopic.php?f=10&t=2425 2. http://ubuntuforums.org/showthread.php?t=1422476 3. https://github.com/saconswl/Real_time_air_pollution_Mod_Proj-2013-2014/blob/home/working_notes/wn_2014-05/Installing_netcdf_python_in_Ubuntu12.04.md 4. http://ubuntuforums.org/showthread.php?t=1464768 5. http://www.unidata.ucar.edu/support/help/MailArchives/netcdf/msg10293.html


In some instances films had not been certified before the website was uploaded.
Child and Family tickets purchased before a film is certified as 15 or over can be refunded. Please contact Guest Services before the performance for a refund, as admission may be refused on the day.
A U film should be suitable for audiences aged four years and over, although it is impossible to predict what might upset any particular child.
U films should be set within a positive framework and should offer reassuring counterbalances to any violence, threat or horror. If a work is particularly suitable for pre-school children, this will be indicated in the ratings info.
General viewing, but some scenes may be unsuitable for young children. A PG film should not unsettle a child aged around eight or older.
Unaccompanied children of any age may watch, but parents are advised to consider whether the content may upset younger, or more sensitive, children.
Films classified 12A contain material that is not generally suitable for children aged under 12. No one younger than 12 may see a 12A film in a cinema unless accompanied by an adult. Adults planning to take a child under 12 to view a 12A film should consider whether the film is suitable for that child.
To help them decide, we recommend that they check the Ratings info for that film in advance. No one younger than 12 may rent or buy a 12 rated video work.
Suitable only for persons of 15 years and older. Please note: proof of age may be required.
No one younger than 18 may see an 18 film in a cinema. Adults should be free to choose their own entertainment. Please note: proof of age may be required


Tuples
A tuple is a data type which stores other data types in an ordered index. For example, a tuple can store integers, floats, strings, and even other tuples. You cannot add to or remove data from a tuple once it has been created.
The How
Just as a string is denoted by surrounding characters in quotes
my_string = "some text"
Tuples are created by surrounding data in round brackets.
my_tuple = (my_string, 5, "message", 4.7)
To access this stored data, the position of the data, or index, is used. This is done by placing the index in square brackets following the name of the tuple.
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
print(my_tuple[1])
OUTPUT: 5
You may have noticed that even though index 1 was used, the second piece of data was printed. This is because tuples are indexed starting at 0. Here are some more examples to help you understand.
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
print(my_tuple[0])
OUTPUT: some text
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
print(my_tuple[3])
OUTPUT: 4.7
A negative number can also be used for the index of a tuple. In that case, the last item of a tuple is denoted by -1, and the index works backwards from there.
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
print(my_tuple[-1])
OUTPUT: 4.7
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
print(my_tuple[-3])
OUTPUT: 5
Finally, data in a tuple can be accessed in slices in the same way as a string. This is done by indicating the starting item and the ending item, which will not be included. Theses values are separated by a colon and placed within square brackets.
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
print(my_tuple[1:3])
OUTPUT: (5, "message")
Tuples can also be iterated over using a for loop in the same way as a range.
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
for I in my_tuple:
print(i)
OUTPUT: some text
5
message
4.7
Finally, tuples can be used in logic expressions to check if a piece of data is in the tuple, or at a specific index in the tuple.
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
if "message" in my_tuple:
print(True)
OUTPUT: True
my_string = "some text"
my_tuple = (my_string, 5, "message", 4.7)
if my_tuple[0] == "message":
print(True)
OUTPUT: True
The Why
A tuple offers an easier way to store large amounts of related data, especially when a similar action needs to done to that data. For example, storing sets of x, y, z coordinates in a tuple makes sense, as they are only useful as a set.
An example of data that is closely related.
position_one = (3, 2, 5)
position_two = (2, 4, 7)
Delta_X = position_one[0] - position_two[0]
print(Delta_X)
OUTPUT: 1
An example of data that is iterated over.
code = ("red", "green", "blue", "yellow")
guess = ("red", "black", "yellow", "green")
counter = 0
red_count = 0
white_count = 0
for colour in guess:
if colour == code[counter]:
red_count += 1
elif colour in code:
white_count += 1
counter += 1
print("Red", red_count, "White", white_count)
OUTPUT: Red 1 White 2
Practical Uses
A common practice when asking the user for input is to give them a few options to choose from. When combined with a while loop tuples allow a program to easily test if the input is one of the available options.
choice = 0
options = ("y", "n", "q")
while choice not in options:
choice = input("Choose an option", options)
print("Your choice was", choice)
OUTPUT: Choose an option ("y", "n", "q")
USERINPUT: l
OUTPUT: Choose an option ("y", "n", "q")
USERINPUT: y
OUTPUT: Your choice was y
Another practical use of tuples, as shown above, is to organize related data and iterate over it. In this example, the program finds the first positive number divisible by the numbers (2, 3, 7). By writing the program using a tuple, it is easy to change the requirements, as they are all organized under one variable.
divisors = (2, 3, 7)
number = 2
divisibility = False
while divisibility is False:
divisibility = True
for i in divisors:
if number % i != 0:
divisibility = False
break
number += 1
print(number)
OUTPUT: 43
Practice Problem
Your problem is to take two coordinates and calculate the equation of the line they make.
HINT: a line can be represented by the equation y - y1 = m * (x-x1) where m represents the slop and y1 and x1 represent the values of a point.
coor_one = (4, 7)
coor_two = (2, 12)
You must then find which of the following points fall on that line and print them out.
points = ((2, 12), (3, 13), (4, 7), (6, 2), (7, -3), (10, -8), (16, -23.0))
HINT: When you use the index of a tuple to return a value, it will return whatever is at that position, even another tuple. If you’re still stuck, look at nested tuples in Extras.
Hover below to see a possible solution.
coor_one = (4, 7)
coor_two = (2, 12)
points = ((2, 12), (3, 13), (4, 7), (6, 2), (7, -3), (10, -8), (16, -23.0))
m = (coor_two[1] - coor_one[1]) / (coor_two[0] - coor_one[0])
print("y -", coor_one[1], "=", m, "* ( x -", coor_one[0], ")")
for point in points:
if -2.5*(point[0]-4) + 7 == point[1]:
print("The point", point, "is on the line.")
Extras
Nested Tuples:
Tuples can store most other data types, including other tuples. This is done exactly as you would expect, with the syntax
nested_tuples = (("tuple1", 1), ("tuple2", 2))
new_tuple = nested_tuples[0])
print(new_tuple)
OUTPUT: ("tuple1", 1)
As you can see, this returns the tuple. If we wanted to get the second value of this nested tuple, we would use the syntax
print(new_tuple[1])
OUTPUT: 1
This two-step process can be combined into a new syntax
print(nested_tuples[0][1])
OUTPUT: 1
First, nested_tuples[0]
returns the tuple ("tuple1", 1)
. Next, we get the value at index 1 of this new tuple, returning 1.
Nested Tuple Iteration:
You can also iterate over the value in nested tuples, though they must all have the same number of items. This is done by assigning a variable to each index of the nested tuples using the syntax
nested_tuples = (("tuple1", 1), ("tuple2", 2))
for name, number in nested_tuples:
print(name)
print(number)
OUTPUT: tuple1
1
tuple2
2
Enumerate:
The enumerate()
function is useful when you need to iterate through both the items of a tuple and their position within the tuple. The function adds the index of each item to a tuple with each item, making a tuple of tuples and allowing you to iterate through with a counter variable and a variable assigned to the original items.
Bonus: the tuple()
function returns a tuple of the value passed to it, such as range()
, value separated by commas, or the enumerate()
function.
my_tuple = ("a", "b", "c")
print(tuple(enumerate(my_tuple)))
OUTPUT: ((0, "a"), (1, "b"), (2, "c"))
for counter, item in enumerate(my_tuple):
print(counter)
print(item)
OUTPUT: 0
a
1
b
2


Cryptography Glossary
A
- AES: Advanced Encryption Standard
- Authentication: Assurance of identity of person or originator of data
- Authorization: Identity combined with an access policy grants the rights to perform some action
C
- Confidentiality: Protection from disclosure to unauthorized persons
- Cryptographic primitives: are well-established, low-level cryptographic algorithms that are frequently used to build cryptographic protocols for computer security systems. These routines include, but are not limited to, one-way hash functions and encryption functions.
D
- DES: Data Encryption Standard
-
Digital Certificates: A "Certification Authority" signs a "special message" which contains the
name of a user and the user's public key in such a way that "anyone" can verify that the "special
message" was signed only by the "Certification Authority" and as a result trust the user's public
key. This "special message" is termed as a certificate request and it is digitally signed using a
"signature algorithm".
-
Digital Envelopes: The "sender" seals the "message" such that only the "receiver" can open the
sealed message. The message is encrypted with a secret key and the secret key is encrypted using
the receiver's public key.
-
Digital Signatures: The "signer" signs a "message" such that anyone can "verify" that the
message was signed only by the "signer" and thus not modified by anyone else. This can be
implemented using a message digest algorithm and a public key algorithm to encrypt the
message digest.
F
- FIPS: Federal Information Processing Standards 美国联邦信息处理标准
G
- Galois Field: Galois Field, named after Évariste Galois, also known as finite field, refers to a field in which there exists finitely many elements. It is particularly useful in translating computer data as they are represented in binary forms. In mathematics, a finite field or Galois field is a field that contains a finite number of elements. As with any field, a finite field is a set on which the operations of multiplication, addition, subtraction and division are defined and satisfy certain basic rules.
I
- Integrity: Maintaining data consistency
K
-
Key Agreement: Two "communicating parties" agree upon a secret key by exchanging
messages without any prior agreements. Typically this consists of a two-phase key agreement
algorithm. One party initiates the key agreement and this triggers the "first phase" of the key
agreement after which both parties exchange the results of the first phase. After this, both parties
initiate the "second phase" of the key agreement and as a result both parties arrive at the same
secret key.
N
- NIST: National Institute of Standards and Technology 美国国家标准与技术研究院
- Non-repudiation: Originator of communications can't deny it later
P
-
Public Key Cryptography: This crypto-system uses one key for encryption and another key for decryption (also
known as “asymmetric” cryptography); Each user has two keys – one public key, which is revealed to all users, and one private
key, which remains a secret. The private key and the public key are mathematically linked; Encryption is performed with the public key and decryption is performed with the private
key; Examples: RSA, Elliptic Curve Cryptography (ECC).
S
-
Secret Key Cryptography: This crypto-system uses the same key for both encryption and decryption (this is also
referred to as “symmetric” cryptography). Both the sender and the receiver need to have the same key in order to communicate
successfully. Examples: DES, 3-DES, AES, RC4, RC5, etc.


Police: $1M in diamonds taken during Maui Halloween heist
LAHAINA, Hawaii (AP) - An insurance company is offering a $50,000 reward to help find a masked man in a full-length black gown who stole more than $1 million in diamonds from a Hawaii jewelry store on Halloween.
Maui police say the gowned and masked man also wore black gloves to rob Greenleaf Diamonds in Lahaina at gunpoint.
Police say there were no customers inside when he brandished the pistol and demanded three items from the display case. Police say he stole a pink diamond valued at $240,000, diamond stud earrings valued at $378,000 and a platinum “fancy light pink” diamond valued at $450,000.
Jewelers Mutual Insurance Company is offering the reward for information that leads to an arrest and conviction. The company will also pay 10% of the cost of any merchandise recovered through information provided.

Log important business operations.
Important business operations should be logged to help identify attacks in progress and to investigate attacks that have already occured.
Use the following steps to add code to log important business operations:
List important business operations. Make a list of business operations carried out by the application, such as placing orders, manipulating inventory, etc. Identify which of these operations are the most important.
Identify code that performs important business operations. Use the list of important business operations to find code that matches each one. Make a list of functions in this code.
Add logging functionality. Create a separate class or library to handle auditing and logging. Take time to design this library or class carefuly. Consider functionality to send logs to a remote log server. One of the most common protocols for interfacing with a remote log server is syslog (RFC 5424). Create and document an API for logging events with an adequate amount of information.
Add code that logs important business operations. Use the list of functions that carry out important business operations and add code to each function to use the logging API to make records when important business operations take place. Log both successful and failed events. Record success and failure indications.


We will make our decision based on the suitability of your business and the quality of the project.

I grew up playing drums, and not in the most typical way a drummer is thought of these days.
Jazz was the music of choice for me, and to this day, it is my favorite genre and style of playing.
Here is a list of my top five jazz songs I beleive everybody should listen to at some point in life:
- "All Blues" - Miles Davis
- "Take Five" - Dave Bruebeck
- "Autumn Leaves" - Cannonball Adderley
- "Moanin'" - Art Blakey
- "Blue Train" - John Coltrane
It just so happens that these top five songs are also performed by my top five jazz musicians.
This list is just the beginning, there is so much more to discover...
Here is a glimpse into some of my favorite artwork, but with a twist:

IT TAKES A VILLAGE TO RAISE A CHILD,
AND IT TAKES A VILLAGE TO SAVE A CHILD
Several countries do not have enough ambulences or emergency numbers people can use if they are ever in an emergency. In countries where first responders in abundance, people are reluctant to use them because of the high cost and slow response time due to traffic. First Aid hopes to combat this by using the community to help out neighbors in their time of need. "first responders" are volunteers from within the community that have cars and are willing to drive people to the hospital in emergencies. While they are waiting for the first responder and/or on route to the hospital, First Aid will provied them with medical procedures through IBM Watson that they can do. The descriptions they give of the injuries will also be used to notify the hospital so that they can prepare for the patients arrival. We hope no one is ever in a stituation where they need to use First Aid, but if they do, we hope it is helpful.

I'm a self taught web developer from Tamilnadu, IN. I'm currently learning Java development with FreeCodeCamp. I also have degrees in Mechanical Engineering and Sustainability so I can't wait till I get to the point where I can jump into the more interactive data visualizations and put what I'm learning to good use. But for now I'm having fun learning the basics!

We are developing a Python based environment for experimental modal analysis.
The first public presentation will be at the www.icoev.org conference (Ljubljana, Sep 2015).
The code is not yet public; however, we plan to go public early 2016.
OpenModal was started by PhD graduates of www.ladisk.si


Birthday attack/birthday paradox
The birthday-paradox is a phenomenon from the theory of probabilities, where the statistical probabilities of two similar incidents are surprisingly very different.
Usually the following two scenarios are compared to make this evident:
Answer: At least 253 people must be there, that the probability is higher than 50%, that the host is not the only birthday celebrant.
On the opposite there are only 23 guests necessary, that the probability is higher than 50%, that two of the guests have the same birthday (which date does not matter).
Because of the big difference between 253 guests in the first scenario and 23 guests in the second scenario, this is called a paradox.
Details how to get to these numbers can be found in Methoden und Werkzeuge für Angriffe auf die digitale Signatur, 2003 by Jan Blumenstein.
Transferring this example to the search for hash value collisions means:
If changes are allowed at both documents instead of keeping one document fixed, then one needs to calculate the hash values of a dramatically less number of changed documents to find 2 documents with the same hash value.
If the initial document isn't allowed to be changed and one uses a 128-bit hash function, then you need to calculate 2127 hash values of changed documents to achieve a probability of 50% to find another document with the same hash value (2127 ~ 1,7 * 1038).
The birthday attack allows you to break 128-bit hash functions after 264 calculations: The changes are made at both documents – analogous to the 2nd example above it doesn't matter, which hash value (birthday) is found. It is only important that they are equal (264 ~ 1,8 * 1019).
Because an effort of 264 calculations is possible using a big number of computers working in parallel, 128-bit hash functions are no more considered to be secure for strong cryptography.

API
Each step element can have the following data properties set:
- data-x: cartesian coordinates: X Position

The blue circles have different weights.
Each blue circle has exactly one yellow square that has the same weight.
Use the scale on the right to compare the weight of two blue circles a blue circle and a yellow square.
Sort the blue circles into the gray circles from the lighter to the heavier.
Use the scale as few times as possible. To get a full score, use the scale at most 16 times.
Take the weight A, and compare it to the other two weights. This will allow us to know in which gray circle to put the weight A. There are three possible cases.
If A is lighter than B and C, alors A will go in the gray circle to the left, because it is the lightest. It only remains then to compare B and C to know in which order to put them away.
If A is heavier than B and C, so A will go into the gray circle on the far right because it is the heaviest. It remains then more than to compare B and C to know in which order to put them away.
If A is lighter than any of the other weights, so A will go into the middle gray circle. The lighter weight than A will go to his left, and the heavier weight than A will go to his right.
Take the round A, and compare it to the 4 square weights. This will allow us to know in which gray circle to put the weight A. There are 4 possible cases.
If A is equal to a square weight, and lighter than the other 3, then A will go into the gray circle to the left.
If A is equal to a square weight, is lighter than 2 other squares, and heavier than another square, then A will go into the second gray circle.
If A is equal to a square weight, is lighter than another square, and heavier than two other squares, then A will go into the third gray circle.
If A is equal to a square weight, and heavier than the other 3, then A will go into the gray circle all the way to the right.
In the following, suppose that E is the square that has the same weight as A. Once you've put A in its place, you have to put away the other round weights.
If we were in the 1 or 4 case described above, then the problem of storing the remaining three rounds (i.e. B, C, D) using the three squares whose weight is different from A (that is, say F, G, H) is exactly the same problem we had at the beginning, we just have more than 3 circles and 3 squares instead of having 4 of each. We can proceed in the same way, by comparing B with the 3 squares, in order to determine its position.
If we were in the 2 b> case, we know a square that is the only one heavier than A. Just compare this square with the rounds B, C, and D to determine which of these rounds has the same weight as this square . We will know that this round is the heaviest weight, to be placed in the gray circle on the far right.
Similarly, if we were in the 3 case, we know a square that is the only lighter than A. Just compare this square with the rounds B, C, and D to determine which of these rounds has the same weight as this square . We will know that this round is the lightest weight, to be placed in the gray circle on the left.
Once one of these steps above, we are in a situation where we have more than 2 rounds and 2 squares to put away. By comparing one of these circles to the other two squares, we can deduce whether the round considered is the lightest or heaviest of the two remaining rounds. That's enough to put the last two circles in their place.
We proceed in the same way as in the 3-star version, simply by performing more steps.


Too long, didn't read: Antimatter principle is a powerful thing to use in ripping down destructive power structures inside an organization. But for some reason the concept of empathy is not something we see "real" or tangible, even though there's little that's more of so.
Antimatter principle is something that is catching fire in the wild. That is something splendid. I'm ever so happy that I got interested in the matter. I'm hugely thankful to Mr. Bob Marshall for being ever so insightful to come up with methods like this, and to Torbjörn Gyllebring to make me dive deeper into soothing waters.
Not long ago I was invited to talk about Rightshifting to a local office of one certain company. Experience that I can only describe as "very pleasant one", and one that hopefully has some further consequences of the better kind. Rightshifting, as a subject is pretty fun to talk about since it tends to resonate very well with the crowd. Most of us do have experiences that are easily recognizable from the Marshall model segmentation, so we're very happy with the image that gets painted.
However, I can't really say I'm surprised that when the subject starts steering towards the actual transition on the model to the right (thus: Rightshifing) the discussion gets toned down a little.
There's demand for something tangible. We start to be desperate for something that's... mechanic. Something that we can install on our system to steer onto right path. Shit, we might even want to give a dollar to someone who asks us how we feel and what we should do to get better, and we might pay the dollar to the darling and think we're fine. We're fine, since we do. But we ain't fine, because we ain't.
We need to be.
And being something and reflecting on something that we'd might want to be. just don't come easy to us. Especially after we're rigged on exploring the system which holds the mechanics on steering our work. And that is a powerful thing, and we should clean up the waste as we encounter, but that will only get us so far.
We don't work with our hands.
Thus, in that context, after explaining the basic property, and the only property of Antimatter principle, which is "Attend to folks’ needs", it might feel a bit peculiar why there's still need for something more tangible.
Because that is pretty tangible when you think about it. That is about as tangible as it will ever get in organizations that suffer, that are ill. Many, most, are ill because of fear. Fear is tangible.  That is tangible.
Things we fear are many. We fear we don't do enough. We fear that when people don't do as we are taught things go awfully wrong. We fear, that if we can't keep the position we're in, we're forgotten. We fear getting fired. We fear getting bored. We fear each other. We fear we don't understand the process. We fear we lose the big bid. We fear change, we fear change making us obsolete.
The fear is what we must change. The fear is our needs coming unmet. Now imagine if the fear would lose its value. There's very little to fear if you can be sure that, in the event of change, it would be taken care that you would not feel obsolete. You might then even initiate the change yourself.
The fear is what can be fought against by attending to needs. It's self-accelerating cycle; less space for fear will be fodder for building up caring. It doesn't get much more tangible than that.
We don't work with our hands.

Use cases
Frequent uses of modal windows include:
- Drawing attention to vital pieces of information. This use has been criticised as ineffective because users are bombarded with too many dialog boxes, and habituate to simply clicking «Close», «Cancel», or «OK» without reading or understanding the message.
- Blocking the application flow until information required to continue is entered, as for example a password in a login process. Another example are file dialogs to open and save files in an application.
- Collecting application configuration options in a centralized dialog. In such cases, typically the changes are applied upon closing the dialog, and access to the application is disabled while the edits are being made.
- Warning that the effects of the current action are not reversible. This is a frequent interaction pattern for modal dialogs, but it is also criticised by usability experts as being ineffective for its intended use (protection against errors in destructive actions) due to habituation. Actually making the action reversible (providing an «undo» option) is recommended instead.
Modal window
A modal window blocks all other workflow in the top-level
program until the modal window is closed, as opposed to modeless dialogs that allow
users to operate with other windows. Modal windows are intended to grab the user’s full
attention. Users may not recognize that a modal window requires their attention,
leading to confusion about the main window being non-responsive, or causing loss of the
user’s data input intended for the main window (see Mode error).

This is an addon starter template for the Ionic Framework.
This template does not work on its own. It is missing the Ionic library, and AngularJS.
To use this, either create a new ionic project using the ionic node.js utility, or copy and paste this into an existing Cordova project and download a release of Ionic separately.
Take the name after ionic-starter-
, and that is the name of the template to be used when using the ionic start
command below:
$ sudo npm install -g ionic cordova
$ ionic start myApp tabs
Then, to run it, cd into myApp
and run:
$ ionic platform add ios
$ ionic build ios
$ ionic emulate ios
Substitute ios for android if not on a Mac, but if you can, the ios development toolchain is a lot easier to work with until you need to do anything custom to Android.
http://plnkr.co/edit/qYMCrt?p=preview
Issues have been disabled on this repo, if you do find an issue or have a question consider posting it on the Ionic Forum. Or else if there is truly an error, follow our guidelines for submitting an issue to the main Ionic repository. On the other hand, pull requests are welcome here!

Hi Christian,

actually this has been on my todo list for some time: I tend to use stl

containers here and there in my branchings, so the nice thing here would

be providing some allocators that allocate from space memory, which

would enable us to use things like std::set, std::unordered_set etc.

without hassle. Another nice thing is that I would no longer need to

enforce calling destructors of members manually in "dispose()". I'll

take a look at the space memory API to see whether it's possible.

I agree, it would be nice to have such thing in gecode. I have been using an implementation of such allocator (attached to this mail). It would be nice if we can discuss and improve it. I got this implementation from Stéphane Zampelli.

Regards,

Gustavo

Filip

The Birmingham International Tattoo will return in 2020 - here’s how to get tickets
Tickets for the royal affair at Arena Birmingham on Saturday 28 and Sunday 29 November 2020 are now on sale
by Scott Dickinson, https://www.birminghammail.co.uk/authors/scott-dickinson/Tickets for the royal affair at Arena Birmingham on Saturday 28 and Sunday 29 November 2020 are now on sale.
The Tattoo, which will hold approximately 1,200 performers this weekend, is set for a grand return in 2020.
Culminating marching bands and jaw dropping displays, the show will feature a Grand Finale that has repeatedly wowed spectators for years on end.
The three hour extravaganza is led by the world-famous Band and Corps of Drums of Her Majesty’s Royal Marines, and we’ve welcomed marching bands from France, Poland and the Netherlands to join our home grown talent in the past.
The Birmingham International tattoo will come to Birmingham Arena on Saturday 28 and Sunday 29 November 2020 and tickets can be purchased here.
The event has become an annual tradition in Birmingham and a proud showcase of military activity.
The spectacle of pomp and pageantry has previously included appearances from the Kilgore Rangerettes, Royal Air Force Cosford Queen’s Colour, the RNRMC Field Gun Competition, guest vocal soloists and the Parade of Massed Standards.
The tattoo remains a must-see for the British public, with arena goers flocking to the show to marvel at the astonishing production values. Many people even admit to being brought to tears by the incredible showcase of British heroism.
It seems only appropriate that Arena Birmingham, the city’s biggest venue, has been selected to helm the momentous event.
The Birmingham International Tattoo will come to Birmingham Arena on Saturday 28 and Sunday 29 November 2020.
Tickets are available now and can be purchased from The Ticket Factory Here.
