XMPProperty getProperty(String schemaNS, String propName) throws XMPException
All of the functions return an object inherited from PropertyBase
or
null
if the property does not exists. The result object contains the value of
the property and option flags describing the property. Arrays and the non-leaf levels of
nodes do not have values.
See PropertyOptions
for detailed information about the options.
This is the simplest property getter, mainly for top level simple properties or after using the path composition functions in XMPPathFactory.
schemaNS
- The namespace URI for the property. May be null
or the empty
string if the first component of the propName path contains a namespace prefix. The
URI must be for a registered namespace.propName
- The name of the property. May be a general path expression, must not be
null
or the empty string. Using a namespace prefix on the first
component is optional. If present without a schemaNS value then the prefix specifies
the namespace. The prefix must be for a registered namespace. If both a schemaNS URI
and propName prefix are present, they must be corresponding parts of a registered
namespace.XMPProperty

- The name of the array. May be a general path expression, must not be
null
or the empty string. Has the same namespace prefix usage as
propName in getProperty()
.itemIndex
- The index of the desired item. Arrays in XMP are indexed from 1. The
constant XMPConst.ARRAY_LAST_ITEM
always refers to the last existing array
item.XMPProperty

.XMPException
- Wraps all errors and exceptions that may occur.XMPProperty getStructField(String schemaNS, String structName, String fieldNS, String fieldName) throws XMPException
The names of fields should be XML qualified names, that is within an XML namespace. The path syntax for a qualified name uses the namespace prefix. This is unreliable since the prefix is never guaranteed. The URI is the formal name, the prefix is just a local shorthand in a given sequence of XML text.
schemaNS
- The namespace URI for the struct. Has the same usage as in getProperty.structName
- The name of the struct. May be a general path expression, must not be
null
or the empty string. Has the same namespace prefix usage as

.fieldNS
- The namespace URI for the field. Has the same URI and prefix usage as the
schemaNS parameter.fieldName
- The name of the field. Must be a single XML name, must not be
null
or the empty string. Has the same namespace prefix usage as the
structName parameter.XMPProperty
containing the value and the options or
null
if the property does not exist. Arrays and non-leaf levels of
structs do not have values.XMPException
- Wraps all errors and exceptions that may occur.XMPProperty getQualifier(String schemaNS, String propName, String qualNS, String qualName) throws XMPException
The names of qualifiers should be XML qualified names, that is within an XML namespace. The path syntax for a qualified name uses the namespace prefix. This is unreliable since the prefix is never guaranteed. The URI is the formal name, the prefix is just a local shorthand in a given sequence of XML text.
Note: Qualifiers are only supported for simple leaf properties at this time.
schemaNS
- The namespace URI for the struct. Has the same usage as in getProperty.propName
- The name of the property to which the qualifier is attached. May be a general
path expression, must not be null
or the empty string. Has the same
namespace prefix usage as in getProperty()
.qualNS
- The namespace URI for the qualifier. Has the same URI and prefix usage as the
schemaNS parameter.qualName
- The name of the qualifier. Must be a single XML name, must not be
null
or the empty string. Has the same namespace prefix usage as the
propName parameter.XMPProperty
containing the value and the options of the
qualifier or null
if the property does not exist. The name of the
qualifier must be a single XML name, must not be null
or the empty
string. Has the same namespace prefix usage as the propName parameter.
The value of the qualifier is only set if it has one (Arrays and non-leaf levels of structs do not have values).
XMPException
- Wraps all errors and exceptions that may occur.void setProperty(String schemaNS, String propName, Object propValue, PropertyOptions options) throws XMPException
setters
all take a property specification, their
differences are in the form of this. The first two parameters are always the top level
namespace URI (the schema
namespace) and the basic name of the property being
referenced. See the introductory discussion of path expression usage for more information.
All of the functions take a string value for the property and option flags describing the property. The value must be Unicode in UTF-8 encoding. Arrays and non-leaf levels of structs do not have values. Empty arrays and structs may be created using appropriate option flags. All levels of structs that is assigned implicitly are created if necessary. appendArayItem implicitly creates the named array if necessary.
See PropertyOptions
for detailed information about the options.

rampTo
In Tone.js, many of a class' members are
Tone.Signals.
Working with signals is different than working with numbers or strings:
Signals are values which are updated at audio rate,
which allows for sample-accurate scheduling and ramping.
.rampTo(value, rampTime)
smoothly changes the signal from the current value to the target value over the duration of the rampTime.
This example uses
.rampTo
in to smooth out changes in volume and frequency.

 The referee allegedly immediately told then-assistant coach Jim Jordan, who shrugged him off, according to NBC News.
Jordan’s office did not immediately respond to a request for comment.
 The congressman has denied the allegations and claims that the people coming forward are politically motivated.
Independent investigators found that Strauss had sexually assaulted at least 177 boys over twenty years.

As advised in the Disappearing artwork thread I reverted to the older Synergy. I continue to have the problem of no artwork from iTunes. I read the issue is with iTunes. I'm wondering why CoverSutra and TuneBar work fine. (Well, they are pathetic at trying to be Synergy but they do not have the artwork problem.)

China criticises US senator over Hong Kong bill
The US bill would re-examine Washington's special treatment of Hong Kong.
China's foreign ministry on Wednesday criticised a United States senator for saying he wanted to push forward a bill supporting the months-long anti-government protests in Hong Kong.

Violence brings Hong Kong to 'brink of total breakdown': Police
US Senator Jim Risch, a Republican, called himself a "strong proponent" of the Hong Kong Human Rights and Democracy Act and urged its passage.
The bill would re-examine Washington's special treatment of Hong Kong.
Chinese Foreign Ministry spokesman Geng Shuang attacked Risch, saying he had "turned a blind eye to the blatant beating, smashing and burning perpetrated by Hong Kong demonstrators".
"I want to reiterate that Hong Kong is China's Hong Kong. Hong Kong affairs are purely China's internal affairs and cannot be interfered by any external forces," he said.
The protests, now in its sixth month, escalated sharply after an officer shot a protester and a man was set on fire on Monday.
For the third day in a row, protesters caused major train service disruptions, blocked streets and rallied in the central business district.

They hunkered down for expected clashes with police at university campuses.
College students from mainland China are fleeing Hong Kong and classes in primary and secondary schools have been suspended.
Geng also criticised the East Turkistan National Awakening Movement, a Uighur-rights organisation, which published hundreds of coordinates of suspected internment camps in China's far-western Xinjiang region.
Geng called the group's allegations "groundless".
"All lies will collapse when faced with facts," he added.
Experts say China has held one million Muslim members of Xinjiang's Turkic Uighur ethnic minority and other groups inside mass detention facilities.
Associated Press journalists have witnessed barbed wire, high walls and guard towers at some of the facilities, which Beijing calls vocational training centres.

The intercept is the value of our output/target variable when all our features are zero and our function crosses the \( y \)-axis (for a one-dimensional case).
Printing the MSE, we see first that both methods give the same MSE, as they should. However, when we move to for example Ridge regression (discussed next week), the way we treat the intercept may give a larger or smaller MSE, meaning that the MSE can be penalized by the value of the intercept. Not including the intercept in the fit, means that the regularization term does not include \( \beta_0 \). For different values of \( \lambda \), this may lead to differing MSE values.
To remind the reader, the regularization term, with the intercept in Ridge regression is given by
$$ \lambda \vert\vert \boldsymbol{\beta} \vert\vert_2^2 = \lambda \sum_{j=0}^{p-1}\beta_j^2, $$but when we take out the intercept, this equation becomes
$$ \lambda \vert\vert \boldsymbol{\beta} \vert\vert_2^2 = \lambda \sum_{j=1}^{p-1}\beta_j^2. $$For Lasso regression we have
$$ \lambda \vert\vert \boldsymbol{\beta} \vert\vert_1 = \lambda \sum_{j=1}^{p-1}\vert\beta_j\vert. $$It means that, when scaling the design matrix and the outputs/targets, by subtracting the mean values, we have an optimization problem which is not penalized by the intercept. The MSE value can then be smaller since it focuses only on the remaining quantities. If we however bring back the intercept, we will get an MSE which then contains the intercept. This becomes more important when we discuss Ridge and Lasso regression next week.

The end of WYSIWYG?: "There is also live-previewing which allows people to easily try permutations and options without having to commit changes"
This sounds interesting; lots of apps already do it, of course, but it seems that with processing power on the desktop having improved massively over the last 10 years, it's ripe to be rolled into the UI as a general principle... in many ways GUIs were the same, there were people doing WIMP interfaces with character-based displays back in the day, well before Windows/GEM/etc did it.

English is a varied subject and most pupils are talented in at least one aspect of it. Our choice of books, methods and subject matter recognises talents and encourages pupils to teach their full potential.
Pupils are taught to speak and write in a variety of different modes and the study of literature plays an important part in the course. The continuous assessment of written coursework is important throughout the five years of the course. Students are also taught how to write effectively under timed conditions in preparation for public examinations. Oral skills are emphasised and students are taught to listen and respond in a variety of different situations.
All pupils study a GCSE course appropriate to their own interests and abilities. Careful setting here, as elsewhere, enables us to match the demands of the course and the chosen texts very precisely to the needs of pupils.
'A' level English is a very popular course. Students study a syllabus, which has a coursework element and an open book examination. Charters was the first school in Berkshire to follow this syllabus and has achieved excellent results.
There are also many extra-curricular activities including theatre visits, poetry workshops and
public speaking competitions.
The Mathematics Faculty aims to help all pupils experience success in Mathematics. We also want pupils to develop an awareness of the fascination and power of Mathematics as well as a confidence in their own ability so that they achieve high standards.
Mathematics lessons include problem solving, investigational and practical work both with and without calculators (which may be scientific or graphical) as well as more traditional work.
Our aim is to make our pupils aware of the challenging, but rewarding, and enjoyable nature of the unique subject that Mathematics is.
In Year 7, pupils work for half a term in mixed-ability groups before being put into sets. From then until the beginning of Year 10, in each half-year group of five sets, there will be twice-yearly movements between sets to reflect any changes in the relative performance of pupils.
All pupils take their National Curriculum test at the end of Year 9 and their GCSE at the end of Year 11.
Mathematics is a popular subject at 'A' level, where we study Pure Mathematics, Statistics
and Mechanics modules, and we also offer a one year course for those in the Sixth Form who wish to improve their GCSE grades.
The Faculty of Science aims to make Science Education interesting and relevant and to enable all pupils to reach their potential. We help our students to share the excitement and enjoyment which scientific discovery and increasing scientific knowledge can bring.
In the Lower School, we have a modular course. Students begin with three induction modules which develop their experimental and scientific reasoning skills. These include the use of datalogging and computer modelling. Fifteen units of work are then studied, culminating in the National Tests at the end of Year 9. In each Year, students receive a balance of Physics, Chemistry and Biology.
In Years 10 and 11, the Science Faculty offers two courses, NEAB Co-ordinated Science and NEAB Modular Science. Although the organisational and assessment arrangements differ, both courses are broad and balanced in content, lead to a dual GCSE award and occupy 20% of the students school time.
Success in these courses could lead to further scientific study at GCE Advanced level in Biology, Chemistry and Physics.
The Faculty organises and supports many extra curricular events ranging from Electronics
Club and Environment Club in Year 7 to Work Experience for Sixth Form students. In addition,
students will have the opportunity to meet and work with scientists from industry and other
areas during the course of their studies.
The Faculty aims to provide introductory language courses, which are both enjoyable and relevant, to enable pupils to communicate on a basic personal level with native speakers and to generate an enthusiasm for the study of foreign languages in general.
Pupils are taught to understand, speak, read and then write in the foreign language using a variety of teaching strategies to take account of differences in pupil ability.
French is the first foreign language taught to all Year 7 pupils and this is being done via a number of topics - an approach continued through successive years. In Year 8, all pupils begin additionally to learn Spanish.
It is a statutory requirement that all pupils study at least one modern language to GCSE level and, where appropriate; they are encouraged to continue with the study of both. Both languages are also taught to 'A' level.
Charters is fortunate in having French and Spanish native speakers in the Faculty, in addition to two foreign language assistants from the same countries.
Because of the communicative nature of these subjects, it is essential that pupils be given
opportunities to reinforce their language learning abroad and, accordingly, there are day
study visits, exchanges and work experience placements.
The work undertaken in this Faculty is in line with the latest developments in GCSE and
National Curriculum.
ART
Art activities are designed to promote the development of skills enabling pupils to express
themselves creatively. A comprehensive range of technical competencies is taught within the
context of critical and historical studies. Drawing from observation, imagination and
experience are the basis of all work.
DRAMA
Creating drama - by exploring texts, researching, improvising and structuring ideas -
challenges pupils to respond actively, developing modes of self-expression and confidence
through performance. Imagination, problem-solving and decision-making are fostered.
Group work encourages social interaction skills, improving awareness and consideration for
others. Examination courses widen study to the technological aspects of Theatre Arts.
MUSIC
We aim to promote a better understanding and appreciation of Music through active involvement in listening, performing and composing. This is a practical course in which the pupils experience a variety of musical cultures and traditions and have the opportunity to take part in extra-curricular activities and concerts. Peripatetic support is provided for those pupils who wish to learn an instrument.
In Art, Drama and Music, study visits are made to relevant places of interest to support
examination coursework.
Special Educational Needs, PSE, Careers, Work Experience, Community Service, and National Records of Achievement.
At Charters we provide for the individual needs of pupils. Those pupils with Special Educational Needs are identified and assisted throughout their School career by Specialist Teachers overseen by the Head of Special Educational Needs. A system of support, including assistance from outside agencies, helps pupils who have learning problems.
Statemented pupils with disabilities are usually integrated in all aspects of the curriculum and all statemented pupils will receive some NTA support in the classroom and help from the Sixth Form Community Service programme. Full-time welfare assistants are employed to cater for the general welfare of the physically disabled and are based in the Resource Centre.
All pupils follow a tutorial programme. Additionally, Personal and Social Education is part of the Core Curriculum in the Upper School. In Year 7, the tutor period is taught by form tutors and in Years 10 to 13 an experienced team is responsible for an extended programme which includes Careers, Work Experience and National Records of Achievement which prepares pupils for adult life. Outside agencies such as 'The Careers Service' support the School's programme.
Modules of work involving personal relationships and drugs education follow Statutory Guidelines
and are taught in appropriate contexts.
This curriculum area includes some of the subjects that help to understand people: Geography, History, Religious Education, Sociology and Psychology. It aims to provide all pupils with knowledge and understanding that will enable them to take an active and informed part in society.
Geography will enable pupils to understand major problems and issues in the world and to acquire useful skills for work and leisure. History promotes understanding of the past, leading to an understanding of the modern world. Geography builds fieldwork skills using the local area, Tirabad and further afield e.g. the South of France. History visits places such as the Somme battlefields and Kentwell: a Tudor house in Suffolk.
Geography and History are taught as separate subjects in Years 7 to 11 and are options in Years 10 and 11. They are popular and successful 'A' levels.
Religious Education is provided in accordance with the Agreed Syllabus for Religious Education adopted by the Royal Borough of Windsor and Maidenhead. Parents may request that their child be withdrawn on those occasions when Religious Education is taking place.
Religious Education helps to explain many aspects of History, to define beliefs and values, and to contribute to moral development. Above all, it helps a pupil gain understanding different beliefs, experiences and practices.
Religious Education is timetable in Years 7 to 9. It is an option in Years 10 and 11 and part of the PSE programme. It is also an expanding 'A' level.
Sociology and Psychology are increasingly popular 'A' levels.
The Business Faculty brings together those subjects from the school curriculum that relate directly to the world of work.
The I.T. department is responsible for ensuring all pupils will learn and develop I.T. skills throughout their time at school. The groundwork is laid in Year 7 with dedicated lessons, but skills are developed in each curriculum area until Year 11. Some students opt to take a specialist I.T. GCSE course in Years 10 and 11. The I.T. equipment available is up-to-date and replicates that which is found in industry.
Business Studies is a very popular option at GCSE and provides a good general introduction to the 'world of work'. Pupils can then opt to take a range of Business Courses in the Sixth Form. All of these provide an excellent basis for entry onto degree courses or employment.
Economics is studied only at 'A' level and has an excellent track record in terms of examination results. It is an extremely popular option for Sixth Form students and many students choose to study Economics at degree level.
This curriculum area includes some of the subjects that help to understand people: Geography, History, Religious Education, Sociology and Psychology. It aims to provide all pupils with knowledge and understanding that will enable them to take an active and informed part in society.

Religious Education helps to explain many aspects of history, to define beliefs and values, and to contribute to moral development. Above all, it helps a pupil gain understanding different beliefs, experiences and practices. Religious Education is timetabled in Years 7 to 9. It is an option in Years 10 and 11, and part of the PSE programme, and it is an expanding 'A' level.
Sociology and Psychology are increasingly popular 'A'levels.
The Physical Education Faculty aims to encourage all pupils to take part in a wide range of physical activities and to encourage a positive attitude towards health, fitness and physical recreation.
In Key Stage 3, pupils will participate in a range of sports and also have the opportunity to participate in outdoor pursuits at Tirabad Residential Centre.
During Years 10 and 11, pupils are able to experience new activities not previously offered including weight training, squash and step aerobics. Students will also have the opportunity to choose 3 sports, which will be covered in more depth. Alongside these opportunities, pupils can also opt to study GCSE Physical Education (Short Course) and the Junior Sports Leader Award (JSLA) Course.
All Sixth Form pupils take part in Physical Education and a wide range of activities is available on and off the school site.
As a department we can also offer Physical Education to 'A' level in the Sixth 'Form. As an extension to the JSLA Course, pupils can gain the Community Sports Leader Award in the Sixth Form.
The Physical Education Department aims to encourage a lively interest in all physical activities, which will allow each pupil to develop his/her potential in a number of different area. This can hopefully be achieved not only within PE lessons but during extra-curricular activities where a diversity of after school clubs are available, as well as the opportunity to represent the school in the many school places offered.
Work within the PE curriculum is designed to complement, contribute to and support the
aims of the school. It offers a comprehensive range of experiences to meet the needs
of individual pupils who are encouraged to participate, irrespective of their abilities
and to become actively involved.
Design Technology, through the areas of Resistant Materials, Food Technology, Graphic Products and Textiles, aim to prepare pupils for effective living in a fast changing technological society and in so doing equipping them with the flexibility needed to cope with life and independence.
Through a wide-based curriculum pupils learn to overcome unforeseen problems and adapt their ideas in the light of constraints imposed by the materials, tools and processes available to them. Consideration is also given to the impact of technology on the way we live.
A wide selection of materials are used and pupils learn about the properties of these and methods of combining these to enhance their characteristics. In all areas of this subject, pupils are encouraged to produce practical work of high quality.
Food Technology focuses on using food creatively, nutrition, health and hygiene, consumerism and appliance testing.
In Textiles, pupils investigate different textile materials leading to an understanding of the creative use of colour, texture and pattern in textile items.
Resistant Materials concentrates on wood, metal and plastics. Other areas covered include the use of mechanisms, structures, electronics and the use of I.T. Control Technology to achieve desired outcomes.
This approach is used throughout all years, including GCSE and 'A' levels.

Our fist days starting our final projects was a nerve-racking day. I remember walking into the room in WeWork Tower 49 and getting straight to work. I sat next to my partner Joanna and we started to find a template on StartBootstrap.com. We found one that really stood out to us and look apprpoiate for our idea. We wanted our book generating web app to look formal and attractive.
The day went by, and we encountered so many errors that'd we'd lost count. Even though it got frustrated at times, every error equalled a lesson. We learned more and more as we tried new things and we took help from Melissa, Sarah, Carson, and Sam whenever we couldn't get around something. Of course we felt the most happiness when we fixed an error on our own.
The day was coming to the end, but our website was not even close. We felt the stress rain down upon us, but realized that we had half of a day to finish up the next day. Joanna and I still decided to collaborate on it at home by texting and helping each other. We hadn't gotten the chance to get help on adding an API in camp, but my brother was kind enough to help Joanna and I through it. It was great to walk into camp the next and only having to clean up a few things before the big Demo Day.

2020 Mini JCW GP to debut in LA
The hottest-ever Mini will make its debut at the Los Angeles motor show, with 220kW running through the front wheels.
by Scott Collie- shares
Mini will finally unveil the third-generation John Cooper Works GP at the Los Angeles motor show, packing a 2.0-litre turbocharged engine making at least 225kW.
When it launches, the GP promises to be the fastest-ever road-going Mini. It's the latest in a line of pared-back, track-ready special editions, with production limited to just 3000 units.
According to Mini, the previous-generation JCW GP lapped the Nurburgring in 8:23.00, but the new model has already dipped below eight minutes.
Expect to see a set of "large alloy wheels", a more aggressive body kit, and a large roof-mounted rear spoiler.
The engine will breathe through a set of centre-mounted exhaust pipes, while the car's wheel arches appear to have an aerodynamic role of some sort...
Previous GP models have gone without rear seats, a trait which could well carry over to the car you see here.
Along with the JCW GP, Mini will use the Los Angeles motor show to give its Cooper SE electric vehicle its North American debut.
The Los Angeles motor show kicks off next week. Stay tuned for more from the show floor.

Intro
We’ve all been there…a blank slate can be a very scary, overwhelming roadblock.
“Is coding for me?
How am I ever going to get to a point where coding comes easy?
When will I be able to use this
new
skill to complete a finished project?”
Think about it—first you have to plan, then you have to learn, then you have to be good enough to
create. But before you learn, you have to decide what it is you’re going to learn, and you need to have
a great understanding that the thing you’re learning is going to pay some sort of dividend when all is
said and done.
On the most basic level, coding is how we communicate with computers, and
what we use to build and run websites, apps, video games, and more. Learning to code is like
learning how to speak and write in a particular language; a computer’s language.
Since you're thinking how complex code can get, you might be intimidated every time you see a code
block like this:
i = 0;
while (!deck.isInOrder()) {
print 'Iteration ' + i;
deck.shuffle();
i++;
}
print 'It took ' + i + ' iterations to sort the deck.';
Learning this piece of code is pretty simple when you have covered the basics, it only takes a few
hours or so to grasp the concepts of the language and develop a program that contains code more
advanced than this!
Getting Started
First choose a path you would be like to work and progress on, and then choose a language and start
out with the most basic hello world programs.
Learn online with the links refer to the last page or try it on your machine with an IDE or an
editor like Atom or Visual
Studio Code
Soon enough you would learn the fundamentals of programming such as loops, arrays and data
structures.
When you choose to pursue learning another language later on you will find it very easy and familiar
to code as well. Next would be to learn frameworks and libraries and code projects implementing all
you have learnt.
print 'Hello World!'
a = 5;
print a+5;
This is a much easier example to start programming with,
always go step by step and gradually you'll improve at the concepts.
Check out the other pages to get to know more about languages and good practices for getting started
with programming.
Which languages
do I start with?
There are many platforms and job types to choose from when you start with programming, the following
is in demand and is a good starting point:
Front end / Web
HTML/CSS/JS
So many jobs are related to the web these days, you can’t go wrong being familiar with these
“backbone” technologies before moving onto a framework or library. This is the easiest path to your
first junior development position.
Back End
Python
Python is used in so many applications, from web development, to data science, machine learning, AI,
game development, quick scripts, and is even an embedded language in many applications including
PostgreSQL
C++
C++ is a general-purpose language. It well deserves the widely acknowledged nickname "Swiss Pocket
Knife of Languages." It is very fast, well-structured and secure compared to its predecessor C. It is
still used as critical parts in many systems of today
PHP
PHP is a programming and scripting language to create dynamic interactive websites. It is a server side
scripting language that is embedded in HTML. It is used to manage dynamic content, databases, session
tracking, even build e-commerce sites.
Databases
SQL
Structured Query Language is used in interacting with RDBMS
(Relational Database
Management
Systems)
like Microsoft SQL Server, Oracle, MySQL, and PostgreSQL. Learning datastructures and
algorithms are very important to be a backend or full-stack developer.
Specailites
Java / .NET / Mobile Apps / AI / Machine Learning
These fields have heavy academic principles involved, not just software development skills. It is
recommended for people who have a strong interest in AI / Data Science / Robotics, etc. where more
exposure to that path is preferred.
Good Coding Practices
If you've made it so far means you're getting started on coding, good luck :)
Here are some
things to keep in mind that will you help you to be a better programmer.
Plan
While it is often tempting to jump straight into your editor and start coding, a bit of planning can go
a
long way.
- It gives you solid goals to work towards
- Reduces the amount of "wasted" code
- Reduces code changes
Practice Dryrunning / Debugging
This is essential to learn how the code is interpreted and what is the actual process occuring behind
the scenes.
- It helps with debugging
- Keep track of variables
- Optimize the process of the program
Use clear naming
This is the most basic concept of programming, as code gets changed down the line or by someone else
this is absolutely required to make our code easier to read and understand. Make it as descriptive as
possible.
- Helps enforce separation of concerns
- It makes it easy to quickly skim over code, saving time
- Code becomes easier to maintain or update
Use version control
Source control is a marvellous thing. It's a backup of your code, allows you to track changes, and let's
you quickly roll back in case of any circumstance occuring.
Not to mention it makes life much, much easier when working as part of a team.
- Keeps a backup of every version of code "checked in"
- Easy to share code and track changes made by others
- This will not only be helpful for yourself but your teammates as well.

Here are few links where you can get started with coding.
All the best, have fun!

We will cover more about DSP-C in later chapters. Ericsson uses contract based programing, which helps large teams working together on same software. It allows programmers to define the contracts for each module and/or functions. This style of programming provides a framework where module integration is less error-prone since each developer states the requirements for their modules in the contracts [30]. With this thesis we are providing a verifier to check validity of contracts among the function and/or modules.
We developed techniques to handle Ericsson's parallel software running on multicore DSP platform. The major challenge with the parallel/concurrent software verification includes state space explosion due to several control flow paths of parallel programs. Software architecture used in our case study does not pose state-space explosion issue since the software is statically scheduled and software does not share much data between threads and threads run independent of other threads. We also identified some of the platform features which can be verified using model checking and proposed model checking techniques.
