injuries, players can choose to practice serve/receive, do physical
training or analyze tournament videos. Formal students will only be
charged for 48 weeks within a year, but will get the benefits for
all 52 weeks of an entire year.
If the formal student is representing USA in an international
tournament, the player does not have to pay training fees during
the formal student’s absence. This perk is only available for
formal students.

main coach)
- Reaching Semifinals in US National or US Open Men’s or
Women’s Singles – 2 additional 1-hour private lessons every week
(assigned coach will be determined by club) and each student
will receive $1000 prize money (50% will go to the student and
50% to the student’s main coach)
* Note: There is a maximum of 2 additional private lessons every
week for a student regardless of however many accomplishments
above are achieved. No additional fee needs to be paid for the
additional private lessons.
- Students will receive a replacement DHS blade every 1-2
years, 1-4 sheets of Hurricane rubber every year (only for formal
students who have trained here for at least 3 months).
- Free club clothing (only for formal students who have
trained here for at least 3 months).
- All students will have a main coach assigned to them.
FORMAL STUDENT RULES
- To become a formal student, you must pay a $500 one-time initiation fee (only need to be paid when entering the formal student program).
- Club coaches and formal students fully collaborate with USA National Team Training and Tournaments.
- During training, parents are absolutely prohibited from entering the training area (i.e. picking up balls, interfering with the training session by entering the area and discussing training plan, etc). During training, the coach gets to determine what to do in terms of the student’s training. Parents are welcome to approach the coach before or after the training session with any concerns with regards to the training, but are absolutely prohibited to do so during the training.
- Each student must pay a $300 fee for each US Nationals and a $300 fee for each US Open. This money will be used to pay for the coaches to coach the students during the tournament. The coaches will be there to coach the whole tournament (however, there is no guarantee the coach will be available to coach every match).
- For smaller tournaments, if student would like coaches to coach them during the tournament, each student can pay a $100 fee for each day (however, there is no guarantee the coach will be available to coach every match).
- Student must wear club attire when playing in any tournament. If a student is caught violating this rule, the student will be penalized by the club.
- Students should show up on time. If they are late, no extra time will be given to them for that training session. Once the weekly training times are determined for the student, this time cannot be modified for 3 months. The student has the option to modify training times every 3 months.
- There is a maximum number of formal students that the club can accept. The club will determine the specific number.
- If the formal student is not focused during training, matches, leagues or tournaments, the club will immediately remove his/her eligibility as a formal student.
- If the student will be absent for his/her training session, the club needs to be notified in advance.
- If the student is late for group training, or if the student uses mobile devices (cell phone, iPad, etc) during break, then the student will be put removed from the primary team and put on the secondary team for training.
* Parents can remove their child from being a formal student at any
time effective immediately.
NON-FORMAL STUDENT TRAINING
2 selections:
- $800 for 4 weeks: 8 hours a week. Includes 3 hours of private lesson (1 hour with student’s coach of choice and 2 with another coach at club’s discretion) and 5 hours of group lesson.
- $1000 for 4 weeks: 10 hours a week. Includes 5 hours of private lesson (2 hour with student’s coach of choice and 3 with another coach at club’s discretion) and 5 hours of group lesson.
NON-FORMAL STUDENT RULES
Students should show up on time. If they are late, no extra time will be given to them for that training session. Students do not need to pay membership/initiation fees. Club will only provide training to the students. Students will not be entitled to any of the following perks: club clothing, blades, rubbers, prize money, and tournament coaching (note that these perks are available to formal students only). The non-formal students are permitted to represent any club at tournaments. If all coaches are completely booked and formal students need to add lessons, non-formal students must give up their training timeslot to formal students (at the club management’s discretion).
Other Notes
*Outside of formal and non-formal students, if other people would like to attend the group training on Saturdays and/or Sundays, each training session is 2.5 hours and is $40 for one day, $75 for 2 days, and $260 for 4 weeks of group training. Group training time will be determined.
*Reservation requests for private lessons must be made 24 hours in advance. If reservation requests are made less than 24 hours, then the club management may refuse the reservation.
*All private lesson cancellations must be made 24 hours in advance; otherwise, the student will be
charged the full amount. No exceptions.
*Club management has the right to make the final decision on all issues.


Don’t you just love exploring beautiful and neat sites with a clean user interface? While most of us would reply with an assertive ‘YES,’ little, do we know the kind of effort and skill that goes into making a website attractive and user-friendly. The secret to creating an impressive site is to master the art of front-end development, and no, it is not as easy as it seems!
However, it is not impossible either. Here are five tips that’ll help you get better in front-end design and web development.
-
Commenting
Commenting is one such practice that is often ignored by programmers, especially for codes that are written by multiple programmers. But remember, commenting is an important part of project you create. With proper comments and organised files its always easier for you or others to jump in and understand where things are at and how they work.
-
Invest In Productive Tools.
The Internet is teeming with a host of web development tools, from browser add-ons to smart plugins, the amount of choices available now is massive! So, why not invest in some really productive web tools that’ll help you improve your front-end designing skills? Tools like Sublime Text, jQuery, Emmet, Bootstrap, and Sass are nothing short of a godsend for web developers.
-
Always Be Curious.
A front-end developer has to keep himself/herself updated continuously with the latest news and innovations in the field. You need to take a proactive stand and learn new things about front-end development from informative blogs and videos. Following are some of the most informative and useful learning sources for front-end developers -
-
Refactor Your Code From Time To Time.
By “refactoring” your code, you’re only enhancing the code without tampering with its functionality. This will improve the quality and readability quotient of your code and the more often you do it, your code will continually be updated into a cleaner and fresher version of what it was before. Apart from that, one of the most significant advantages that refactoring offers is that it ensures your code remains free from plagiarism.
-
Version Control
As a developer, version control is something that you must know about. Version control systems let you keep track of changes made to the code over time. And not just this, they also make it easy to revert back to an earlier version if you screw something up. Thus using verion control will save you some sleepless nights for sure. One of the most widely used version control systems is Git. Thus knowing git has been a requirement for almost every development job these days.
While these tips will surely help you become a better front-end designer, in the long run, you must always remember two things while designing your platform – keep it simple and neat, and don’t forget to create your signature style.


The ParaCode Programming Language!
If you are using the python files, run installDependencies.py If you are using the executable file, run the installDependencies executable
pip install ParaCode
from ParaCode import shell
Otherwise, if you want to run ParaCode code without the shell, import ParaCode with
from ParaCode import basic
shell.RunShell()
Otherwise, if you are running ParaCode code without the shell, add the following to your python file
basic.run('<stdin>', 'PRINT("Hello, World!'))
And of course, replace the second argument with the code you want to run
RUN("HelloWorld.para")
And replace HelloWorld.para with the file name
On windows, you can also just open the ParaCode file and it will automatically open in the shell and run
// For Without Color
PRINT("Hello, World!")
ECHO("Hello, World!")
// For Color
PRINT("Hello, World!", "Blue")
ECHO("Hello, World!", "Green")
PRINTCOLOR("Hello, World!", "Yellow")
ECHOCOLOR("Hello, World!", "Red")
# This is a comment like python's
// This is a comment like many other languages
; This is a comment like Assembly's
You can use colors with the corresponding name, or you can use the hex value
PRINT("Hello, World!")

BigInt
public struct BigInt: SignedInteger
An arbitary precision signed integer type, also known as a big integer
.
Operations on big integers never overflow, but they might take a long time to execute. The amount of memory (and address space) available is the only constraint to the magnitude of these numbers.
This particular big integer type uses base-2^64 digits to represent integers.
BigInt
is essentially a tiny wrapper that extends BigUInt
with a sign bit and provides signed integer
operations. Both the underlying absolute value and the negative/positive flag are available as read-write
properties.
Not all algorithms of BigUInt
are available for BigInt
values; for example, there is no square root or
primality test for signed integers. When you need to call one of these, just extract the absolute value:
BigInt(255).abs.isPrime() // Returns false

Returns true if this integer is probably prime. Returns false if this integer is definitely not prime.
This function performs a probabilistic Miller-Rabin Primality Test, consisting of
rounds
iterations, each calculating the strong probable prime test for a random base. The number of rounds is 10 by default, but you may specify your own choice.To speed things up, the function checks if
self
is divisible by the first few prime numbers before diving into (slower) Miller-Rabin testing.Also, when
self
is less than 82 bits wide,isPrime
does a deterministic test that is guaranteed to return a correct result.Declaration

Winston Churchill
Sir Winston Leonard Spencer Churchill (30 November 1874 – 24 January 1965) was a British statesman, army officer, and writer. He was Prime Minister of the United Kingdom from 1940 to 1945, when he led the country to victory in the Second World War, and again from 1951 to 1955. Apart from two years between 1922 and 1924, Churchill was a Member of Parliament (MP) from 1900 to 1964 and represented a total of five constituencies. Ideologically an economic liberal and imperialist, he was for most of his career a member of the Conservative Party, as leader from 1940 to 1955. He was a member of the Liberal Party from 1904 to 1924.

Body found in Ballymun with signs of serious injury
The body was found in a container on Balbutcher Lane on Monday morning
by Conor GallagherA body has been found in a container in Ballymun, Dublin displaying signs of serious injury.
Gardaí are at the scene and have cordoned off the area as they begin their investigation.
The body was found in a container on Balbutcher Lane in Ballymun on Monday morning. It shows signs of multiple and severe injuries.
In a statement the Garda Press Office said: “Gardaí are investigating all the circumstances surrounding the discovery of a body of a man (age currently unknown) in a container in the Balbutcher Lane area of Ballymun.”
“The discovery was made at approximately 10.50am on November 25th. He has been pronounced dead and the body remains at the scene currently pending a technical examination.”

public abstract class FileSystemProvider extends Object
Files
class will typically delegate to an instance of this
class.
A file system provider is a concrete implementation of this class that
implements the abstract methods defined by this class. A provider is
identified by a URI
scheme
. The default provider
is identified by the URI scheme "file". It creates the FileSystem
that
provides access to the file systems accessible to the Java virtual machine.
The FileSystems
class defines how file system providers are located
and loaded. The default provider is typically a system-default provider but
may be overridden if the system property java.nio.file.spi.DefaultFileSystemProvider
is set. In that case, the
provider has a one argument constructor whose formal parameter type is FileSystemProvider
. All other providers have a zero argument constructor
that initializes the provider.
A provider is a factory for one or more FileSystem
instances. Each
file system is identified by a URI
where the URI's scheme matches
the provider's scheme
. The default file system, for example,
is identified by the URI "file:///"
. A memory-based file system,
for example, may be identified by a URI such as "memory:///?name=logfs"
.
The newFileSystem
method may be used to create a file
system, and the getFileSystem
method may be used to
obtain a reference to an existing file system created by the provider. Where
a provider is the factory for a single file system then it is provider dependent
if the file system is created when the provider is initialized, or later when
the newFileSystem
method is invoked. In the case of the default
provider, the FileSystem
is created when the provider is initialized.
All of the methods in this class are safe for use by multiple concurrent threads.

protected FileSystemProvider()
During construction a provider may safely access files associated with the default provider but care needs to be taken to avoid circular loading of other installed providers. If circular loading of installed providers is detected then an unspecified error is thrown.
SecurityException
- If a security manager has been installed and it denies
RuntimePermission
("fileSystemProvider")public static List<FileSystemProvider> installedProviders()
The first invocation of this method causes the default provider to be
initialized (if not already initialized) and loads any other installed
providers as described by the FileSystems
class.

public abstract FileSystem newFileSystem(URI uri, Map<String,?> env) throws IOException
FileSystem
object identified by a URI. This
method is invoked by the FileSystems.newFileSystem(URI,Map)
method to open a new file system identified by a URI.
The uri
parameter is an absolute, hierarchical URI, with a
scheme equal (without regard to case) to the scheme supported by this
provider. The exact form of the URI is highly provider dependent. The
env
parameter is a map of provider specific properties to configure
the file system.
This method throws FileSystemAlreadyExistsException
if the
file system already exists because it was previously created by an
invocation of this method. Once a file system is closed
it is provider-dependent if the
provider allows a new file system to be created with the same URI as a
file system it previously created.

- If the file system has already been createdpublic abstract FileSystem getFileSystem(URI uri)
FileSystem
created by this provider.
This method returns a reference to a FileSystem
that was
created by invoking the newFileSystem(URI,Map)
method. File systems created the newFileSystem(Path,Map)
method are not returned by this method.
The file system is identified by its URI
. Its exact form
is highly provider dependent. In the case of the default provider the URI's
path component is "/"
and the authority, query and fragment components
are undefined (Undefined components are represented by null
).
Once a file system created by this provider is closed
it is provider-dependent if this
method returns a reference to the closed file system or throws FileSystemNotFoundException
. If the provider allows a new file system to
be created with the same URI as a file system it previously created then
this method throws the exception if invoked after the file system is
closed (and before a new instance is created by the newFileSystem
method).
If a security manager is installed then a provider implementation
may require to check a permission before returning a reference to an
existing file system. In the case of the default
file system, no permission check is required.

. The
resulting Path
is associated with a FileSystem

already exists or is constructed automatically.
The exact form of the URI is file system provider dependent. In the
case of the default provider, the URI scheme is "file"
and the
given URI has a non-empty path component, and undefined query, and
fragment components. The resulting Path
is associated with the
default default
FileSystem
.
If a security manager is installed then a provider implementation
may require to check a permission. In the case of the default
file system, no permission check is
required.

FileSystem
to access the contents of a file as a

This method is intended for specialized providers of pseudo file
systems where the contents of one or more files is treated as a file
system. The env
parameter is a map of provider specific properties
to configure the file system.
If this provider does not support the creation of such file systems
or if the provider does not recognize the file type of the given file then
it throws UnsupportedOperationException

This method may be used by the isReadable
,
isWritable
and isExecutable
methods to check the accessibility of a file.
This method checks the existence of a file and that this Java virtual
machine has appropriate privileges that would allow it access the file
according to all of access modes specified in the modes
parameter
as follows:
| Value | Description |
|---|---|
READ |
Checks that the file exists and that the Java virtual machine has permission to read the file. |
WRITE |
Checks that the file exists and that the Java virtual machine has permission to write to the file, |
EXECUTE |
Checks that the file exists and that the Java virtual machine has
permission to execute the file. The semantics
may differ when checking access to a directory. For example, on UNIX
systems, checking for EXECUTE access checks that the Java
virtual machine has permission to search the directory in order to
access file or subdirectories. |
If the modes
parameter is of length zero, then the existence
of the file is checked.
This method follows symbolic links if the file referenced by this object is a symbolic link. Depending on the implementation, this method may require to read file permissions, access control lists, or other file attributes in order to check the effective access to the file. To determine the effective access to a file may require access to several attributes and so in some implementations this method may not be atomic with respect to other file system operations.

[gecode-users] BAB, constrain() and redundant cost constraints
Peter Tiedemann
petert at itu.dk
Sat Apr 14 19:32:06 CEST 2007
I have a quick question on the use of Branch and Bound.
>From the examples Warehouses and Golomb i can see that upon finding a
solution gecode will call constrain() on further spaces in order to
trim the search space so that it only includes better solutions.
This seems to be done by for example posting a linear constraint to
enforce a better a cost on the next solution. My question is simply
this: Isnt it true that these added constraints will accumulate
instead of replacing each other ( which is possible since each should
be tighter than the previous)?
Ie, you start by adding ax < 10, then find a solution with cost 9, and
add ax < 9, but leaving the propagator for ax < 10 alive. I realize
this will only add up to at most the number of variables propagators,
but i just want to make sure i am not missing something here :)
Regards,
Peter Tiedemann

Quantum mechanics, Realtivity, Mathematics and Computer science which make the real world more powerful than it ever been.
Quantum mechanics, also known as quantum physics, quantum theory, the wave mechanical model, or matrix mechanics, including quantum field theory, is a fundamental theory in physics which describes nature at the smallest scales of energy levels of atoms and subatomic particles.
Computational science, also scientific computing or scientific computation is a rapidly growing multidisciplinary field that uses advanced computing capabilities to understand and solve complex problems.
Call to Action »High Performance Computing most generally refers to the practice of aggregating computing power in a way that delivers much higher performance than one could get out of a typical desktop computer or workstation in order to solve large problems in science, engineering, or business.
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics and is used to construct physical models of subatomic particles and quasiparticles.
Mathematics is the study of mathematical concepts independently of any application outside mathematics. These concepts may originate in real-world concerns, and the results obtained may later turn out to be useful for practical applications.

Project IceStorm aims at documenting the bitstream format of Lattice iCE40 FPGAs and providing simple tools for analyzing and creating bitstream files. This is work in progress.
The ice40 UltraPlus devices have a number of new features compared to the older LP/HX series devices, in particular:
Currently icestorm and arachne-pnr support the DSPs (except for cascading), SPRAM , internal oscillators and constant current LED drivers. Work to support the remaining features is underway.
Each MAC16 DSP comprises of 4 DSP tiles, all of which perform part of the DSP function and have different routing bit configurations. Structually they are similar to logic tiles, but with the DSP function wired into where the LUTs and DFFs would be. The four types of DSP tiles will be referred to as DSP0 through DSP3, with DSP0 at the lowest y-position. One signal CO, is also routed through the IPConnect tile above the DSP tile, referred to as IPCON4 in this context. The location of signals and configuration bits is documented below.

Configuration Bits
The DSP configuration bits mostly follow the order stated in the ICE Technology Library document, where they are described as CBIT[24:0]. For most DSP tiles, these follow a logical order where CBIT[7:0] maps to DSP0 CBIT[7:0]; CBIT[15:8] to DSP1 CBIT[7:0], CBIT[23:16] to DSP2 CBIT[7:0] and CBIT[24] to DSP3 CBIT0.
However, there is one location where configuration bits are swapped between DSP tiles and IPConnect tiles. In DSP1 (0, 16) CBIT[4:1] are used for IP such as the internal oscillator, and the DSP configuration bits are then located in IPConnect tile (0, 19) CBIT[6:3].
The full list of configuration bits, including the changes for the DSP at (0, 15) are described in the table below.
| Parameter | Normal Position | DSP (0, 15) Changes |
|---|---|---|
| C_REG | DSP0.CBIT_0 | |
| A_REG | DSP0.CBIT_1 | |

Lattice document a limited number of supported configurations in the ICE Technology Library document, and Lattice's EDIF parser will reject designs not following a supported configuration. It is not yet known whether unsupported configurations (such as mixed signed and unsigned) function correctly or not.
Other Implementation Notes
All active DSP tiles, and all IPConnect tiles whether used or not, have some bits set which reflect their logic tile heritage. The LC_x
bits which would be used to configure the logic cell, are set to the below pattern for each "logic cell" (interpreting them like a logic tile):
0000111100001111 0000
Coincidentally or not, this corresponds to a buffer passing through input 2 to the output. For each "cell" the cascade bit LC0x_inmux02_5 is
also set, effectively creating one large chain, as this connects input 2 to the output of the previous LUT. The DSPs at least will not function unless these bits are set correctly, so they
have some purpose and presumably indicate that the remains of a LUT are still present. There does not seem to be any case under which iCEcube generates a pattern other than this though.
IPConnect tiles are used for connections to all of the other UltraPlus features, such as I2C/SPI, SPRAM, RGB and oscillators. Like DSP tiles, they are structually similar to logic tiles. The outputs of IP functions are connected to nets named slf_op_0 through slf_op_7, and the inputs use the LUT/FF inputs in the same way as DSP tiles.
The CLKHFPU input connects through IPConnect tile (0, 29) input lutff_0/in_1;
and the CLKHFEN input connects through input lutff_7/in_3 of the same tile.
The CLKHF output of SB_HFOSC is connected to both IPConnect tile (0, 28) output slf_op_7 and to the padin
of glb_netwk_4.
Configuration bit CLKHF_DIV[1] maps to DSP1 tile (0, 16) config bit CBIT_4, and CLKHF_DIV[0] maps to DSP1 tile (0, 16) config bit CBIT_3.
There is also an undocumented trimming function of the HFOSC, using the ports TRIM0 through TRIM9. This can only be accessed directly in iCECUBE if you modify the standard cell library. However if you set the attribute VPP_2V5_TO_1P8V (which itself is not that well documented either) to 1 on the top level module, then the configuration bit CBIT_5 of (0, 16) is set; and TRIM8 and TRIM4 are connected to the same net as CLKHFPU.
TRIM[3:0] connect to (25, 28, lutff_[7:4]/in_0) and TRIM[9:4] connect to (25, 29, lutff_[5:0]/in_3). CBIT_5 of (0, 16) must be set to enable trimming. The trim range on the device used for testing was from 30.1 to 75.9 MHz. TRIM9 seemed to have no effect, the other inputs could broadly be considered to form a binary word, however it appeared neither linear nor even monotonic.
The CLKLFPU input connects through IPConnect tile (25, 29) input lutff_0/in_1;
and the CLKLFEN input connects through input lutff_7/in_3 of the same tile.
The CLKLF output of SB_LFOSC is connected to both IPConnect tile (25, 29) output slf_op_0 and to the padin
of glb_netwk_5.
SB_LFOSC has no configuration bits.
The UltraPlus devices have 1Mbit of extra single-ported RAM, split into 4 256kbit blocks. The full list of connections for each SPRAM block in the 5k device is shown below, as well as the location of the 1 configuration bit which is set to enable use of that SPRAM block.

The UltraPlus devices contain an internal 3-channel 2-24mA constant-current driver intended for RGB led driving (SB_RGBA_DRV). It is broken out onto 3 pins: 39, 40 and 41 on the QFN48 package. The LED driver is implemented using the IPConnect tiles and is entirely seperate to the IO cells, if the LED driver is ignored or disabled on a pin then the pin can be used as an open-drain IO using the standard IO cell.
Note that the UltraPlus devices also have a seperate PWM generator IP core, which would often be connected to this one to create LED effects such as "breathing" without involving FPGA resources.
The LED driver connections are shown in the label below.
| Signal | Net |
|---|---|
| CURREN | (25, 29, lutff_6/in_3) |
| RGBLEDEN | (0, 30, lutff_1/in_1) |
| RGB0PWM | (0, 30, lutff_2/in_1) |
| RGB1PWM | (0, 30, lutff_3/in_1) |
| RGB2PWM | (0, 30, lutff_4/in_1) |
The configuration bits are as follows. As well as the documented bits, another bit RGBA_DRV_EN is set if any of the channels are enabled.
| Parameter | Bit |
|---|---|
| RGBA_DRV_EN | (0, 28, CBIT_5) |
| RGB0_CURRENT[1:0] | (0, 28, CBIT_[7:6]) |
| RGB0_CURRENT[5:2] | (0, 29, CBIT_[3:0]) |
| RGB1_CURRENT[3:0] | (0, 29, CBIT_[7:4]) |
| RGB1_CURRENT[5:4] | (0, 30, CBIT_[1:0]) |
| RGB2_CURRENT[5:0] | (0, 30, CBIT_[7:2]) |
| CURRENT_MODE | (0, 28, CBIT_4) |
The IO tiles contain a few new bits compared to earlier ice40 devices. The bits padeb_test_0 and padeb_test_1 are set for all pins, even unused ones, unless set as an output.
There are also some new bits used to control the pullup strength:
| Strength | Cell 0 | Cell 1 |
|---|---|---|
| 3.3kΩ | cf_bit_32 B7[10] | cf_bit_36 B13[10] |
| 6.8kΩ | cf_bit_33 B6[10] | cf_bit_37 B12[10] |
| 10kΩ | cf_bit_34 B7[15] | cf_bit_38 B13[15] |
| 100kΩ (default) | !cf_bit_35 !B6[15] | !cf_bit_39 !B12[15] |
The UltraPlus devices have two IO pins designed for the new MIPI I3C standard (pins 23 and 25 in the SG48 package), compared to normal IO pins they have two switchable pullups each. One of these pullups, the weak pullup, is fixed at 100k and the other can be set to 3.3k, 6.8k or 10k using the mechanism above. The pullup control signals do not connect directly to the IO tile, but instead connect through an IPConnect tile.
The connections are listed below:
| Signal | Pin 23 (19, 31, 0) | Pin 25 (19, 31, 1) |
|---|---|---|
| PU_ENB | (25, 27, lutff_6/in_0) | (25, 27, lutff_7/in_0) |
| WEAK_PU_ENB | (25, 27, lutff_4/in_0) | (25, 27, lutff_5/in_0) |
The UltraPlus devices contain three types of Hard IP: I2C (SB_I2C), SPI (SB_SPI), and LED PWM generation (SB_LEDDA_IP). The connections and configurations for each of these blocks are documented below. Names in italics are parameters rather than actual bits, where multiple bits are used to enable an IP they are labeled as _ENABLE_0, _ENABLE_1, etc.

The I2C "glitch filter" (referred to as SB_FILTER_50NS) is a seperate module from the I2C interface IP, with connections as shown below:

 There are two premises to the film. One, as stated by the Whippet Angel (Melba Moore), is that, "All dogs go to heaven because, unlike people, dogs are naturally kind." The other, amazingly enough, is just the opposite, and the film depicts almost all of the dogs as representing a vast criminal underclass of society. I found these two notions as incongruous and baffling. The bigger problem with the movie however is that there is only one sympathetic character in it, the little human girl Anne-Marie (Judith Barsi who was great as ducky in THE LAND BEFORE TIME), and the dogs are universally unlovable!
As the film starts, two dogs, Charlie (Burt Reynolds) and Itchy (Dom DeLuise), are crooks "on death row", a.k.a. the dog pound, and they are in the process of breaking out. Once out, they go back to the dog Carface (Vic Tayback).  Charlie manages to get back from heaven, but when he comes back, he has not learned any lessons and is up to his old tricks stealing wallets and other nefarious activities.
None of the dogs are characters that the audience cares about. Burt Reynolds provides one of the most bland readings, and I do mean reading, of a script in a long time. Charlie is boring with a capital B, and the voice is his least attractive attribute.
Judith Barsi provides a great voice for Anne-Marie, and the only reason to view this show about dogs is to see this wonderfully sweet and innocent human girl, which, of course, makes no sense at all. In fact, the whole Anne-Marie character is adorable, which leads me to the most distasteful aspect of the picture. Carface is an old, gross bulldog who smokes cigars and keeps young Anne-Marie hostage in his basement. When she escapes, he explains how he "loves her" and must have her back. Maybe I am being way too sensitive, but I kept seeing Carface as being created as too close to a pedophile. Oh well, this was not the main reason I did not like the show. The main reason was that it is boring and holds no interest whatsoever, other than the character of the only human lead, Anne-Marie.
The weak script by David Weiss, et. al., has very few memorable lines, and Charlie gets most of them. When Charlie tries to con Anne-Marie, he tells her, "What a hopeless cad I've been. Blind to the needs of society's unloved." His lame attempts at humor include, "Some of the poorest people I know are as broke as the Ten Commandments." Finally, Charlie's real self comes out as he tells Itchy, "I'm using the girl, and when I'm done with her, I'll drop dump her in an orphanage."
Other than the Anne-Maria character, the only other part with any merit are the drawings. They are a cornucopia of oversaturated colors. The songs written by T. J. Kuenster and Charles Strouse are as bland as bland can be, but the singing by Charlie is even worse. It is so bad that is hard to call it singing. Do you sing in the shower? You are probably more melodious.
 Too bad the editors (John K. Carr and Lisa Dorney) did not have more mercy on the audience and chop out most of Charlie's part. In fact, if the producer had just gotten a whole new set of dogs, it would have been a much more enjoyable film. The show is rated G, but I wonder if PG would not have been more appropriate in a show where characters get shot at with a machine gun and where one goes on a scary dream journey to the deeps of Hell. At any rate, I would be careful with little kids and these scenes. I can not recommend the film although Jeffrey (almost 7) seemed to like it, and I give it a single * for Judith Barsi's Anne-Marie. I hope the recently released ALL DOGS GO TO HEAVEN 2 is better since Jeffrey wants to see it.
**** = One of the top few films of this or any year. A must see film. *** = Excellent show. Look for it. ** = Average movie. Kind of enjoyable. * = Poor show.  Totally unbearable.

But we have already seen that $\mathbb{N}$ and $\mathbb{Z}\times \mathbb{Z}$ are in bijection with each other, in that sense, they are of equal size. Since $\mathbb{Q}$ is sandwiched between the two it ought to be true that $\mathbb{Q}$ has the same size as $\mathbb{N}$, and thus countable.
This reasoning is not incorrect, but an argument is needed to make it an honest proof. This is indicated in the Schröder-Bernstein theorem stated later. Use that to fill the gap in the above argument, or alternately, try to directly find a bijection between $\mathbb{Q}$ and $\mathbb{N}$.
Consider any function $f:\mathbb{N} \rightarrow [0,1]$. We show that it is not onto, and hence not a bijection. Indeed, use the decimal expansion to write a number $x\in [0,1]$ as $0.x_{1}x_{2}x_{3}\ldots$ where $x_{i}\in \{0,1,\ldots ,9\}$. Write the decimal expansion for each of the numbers $f(1),f(2),f(3),.\ldots$ as follows. $$\begin{align*} f(1)&=0.X_{1,1}X_{1,2}X_{1,3}\ldots \\ f(2)&=0.X_{2,1}X_{2,2}X_{2,3}\ldots \\ f(3)&=0.X_{3,1}X_{3,2}X_{3,3}\ldots \\ \cdots & \cdots \cdots \cdots \end{align*}$$ Let $Y_{1},Y_{2},Y_{3},\ldots$ be any numbers in $\{0,1,\ldots ,9\}$ with the only condition that $Y_{i}\not= X_{i,i}$. Clearly it is possible to choose $Y_{i}$ like this. Now consider the number $y=0.Y_{1}Y_{2}Y_{3}\ldots$ which is a number in $[0,1]$. However, it does not occur in the above list. Indeed, $y$ disagrees with $f(1)$ in the first decimal place, disagrees with $f(2)$ in the second decimal place etc. Thus, $y\not= f(i)$ for any $i\in \mathbb{N}$ which means that $f$ is not onto $[0,1]$.
Thus, no function $f:\mathbb{N}\rightarrow [0,1]$ is onto, and hence there is no bijection from $\mathbb{N}$ onto $[0,1]$ and hence $[0,1]$ is not countable. Obviously, if there is no onto function onto $[0,1]$, there cannot be an onto function onto $\mathbb{R}$. Thus, $\mathbb{R}$ is also uncountable.

Hoping to see you soon ☺ !!!!
This institute has a lot to offer for its students, in terms of academics, co-curricular and extracurricular opportunities. With the increased opportunities, often come related problems like stress, anxiety or depression. On face value, these problems might seem trivial, but they end up affecting us in a negative manner. Hence, we should reach out for help. There is nothing to lose.
IIT Ropar houses a great councelling cell consisting of excellent counsellers. Here is an attached PDF for details about IIT Ropar's Counselling cell.
Aim:
The code of conduct is designed to establish a set of guidelines to create a benchmark for ethics and good practice and ensure that mentors conduct their practice in a professional yet, friendly and ethical manner. The code is also meant to inform mentees, and to promote public confidence in the Institute Student Mentorship Program (ISMP) as a process for personal and professional development.
