Here’s an unusual version of salmon en croûte – made with dill, currants and stem ginger.
Preheat the oven to 190C/170C Fan/Gas 5 and line a baking tray with parchment.
Mix together the butter, mace, dill, currants, ginger, salt and pepper in a bowl to make a paste. Place one piece of salmon on a clean work surface, smear the paste on top and lay the other fillet on top of the paste.
Cut the pastry in half and roll out each piece to about 2cm/¾ wider than the size of the salmon. Place one piece of pastry on the lined baking tray and lay the salmon on top. Dab water around the edge of the pastry, then lay the other piece of pastry on top. Press the edges together lightly to seal.
Glaze the top of the parcel with the beaten egg and crimp the edges to finish. Chill in the fridge for 20 minutes and then brush with egg again. Bake for 30 minutes, or until golden-brown.
For the butter sauce place the vinegar, white wine and shallots into a saucepan and cook until reduced in volume by half. Gradually whisk in the butter until a smooth sauce is formed. Season with salt and pepper.
Cut the salmon into slices and serve with the butter sauce.

THEORIES AND MODERN USAGE
Because of the limited historical resources discussing Baybayin, the mystery on its origin and meaning continues to be a mystery until today. However, this does not stop historians from offering their theories. One such theory was presented by Bonifacio Comandante in his PhD dissertation. He claimed that giants clams played a big role in the development of the native script. Comandante drew this theory due to Baybayin characters sharing some resemblance to the shape of giant clams.

Remember the Titans (2000) Review by Steve Kong The Hard Boiled Movie Guide http://boiledmovies.sbay.com/
Jerry Bruckheimer is one of those producers who surprise me from time to time. He can come up with over-the-top stuff like Top Gun, utter garbage like Days of Thunder, and then he has those brilliant moments where he produces marvelously watchable movies like The Rock and Crimson Tide. Remember the Titans falls into the last category, a marvelously watchable and entertaining film out of the Bruckheimer production stalls.
Remember the Titans takes place in 1971. It is a movie that uses football as the backdrop for a story about race relations. A new football coach moves into Alexandria, Va. This coach, Coach Boone (Denzel Washington), is part of an integration program in Alexandria. As events take it, the school board replaces current coach, Coach Yoast (Will Patton) with Boone and this does not settle well.
The conflict in the movie is that of race. The integration of the two major races in Alexandria causes much pain and this is shown in the microcosm present with the players as they go to training camp with coaches Boone and Yoast. Together, the two coaches must both get their racially mixed team working together and also accept each other and work together to win.
Remember the Titans made me emotional from the get-go, something most movies can't do to me even the most polished tear-jerker from Steven Spielberg can't do this! The well-written script by Gregory Allen Howard and the steady direction by Boaz Yakin (Fresh) put me into tears by the end of the film. This movie is the perfect definition of a feel-good film.
Denzel Washington and Will Patton both give excellent performances. Washington is one of the best actors in Hollywood and he lives up to that with his performance in Titans. Patton who doesn't get enough plum roles is given a chance to really perform and he does. The two performances are what nail this movie. The other players are good also, though the script doesn't give us enough time to bond with all the players I got a few of the players confused after a while. But there are two standout performers, they are Wood Harris (as Big Ju) and Ryan Hurst (as Bertier). These two performers are excellent.
Don't Miss Remember the Titans.  But, in the end, Remember the Titans will make you feel good. And Jerry, please produce more good movies like this.

Speech
Elizabeth Truss speaks at the Core Maths Support Programme launch workshop about post-16 maths.
Thanks very much, Steve [Munby, Chief Executive of CfBT ], for that kind introduction. It’s great to be here.
This weekend, at the British Grand Prix at Silverstone, the McLaren Mercedes cars zooming around the track will have a brand new logo on the bonnet front and centre - Your Life.
And that logo - perhaps looking slightly blurred, at high speed - will bring our message to life.
Because the whole point of the Your Life campaign is to show that “maths and science get you everywhere” applies to all young people - girls and boys, no matter where they live or what career they want to do.
And more than any other subject, maths and science can open up a whole world of exciting opportunities.
Just like that car, just like our Formula 1 teams, I believe this country can and should be world-leaders - in maths.
There’s no reason at all why we can’t catch up with, and beat, those high-performing countries currently winning the global race.
The Your Life car can race straight to the front of the pack - we can too. Our ambition is for our young people to become the best mathematicians in the world - and nothing can stop us from achieving it.
Tonight, at Number 11 Downing Street, we’re bringing all the core elements together, right at the heart of government.
There’ll be people from the Your Life campaign - world-leading businesses and universities, and inspiring, innovative people like Eben Upton, who invented the ground-breaking Raspberry Pi computer, Belinda Parmar, CEO of Lady Geek, and our chair, Edwina Dunn, the successful business brain who pioneered Tesco’s Clubcard.
There’ll be people involved in our 2 announcements this week, like many of you - some from our new network of maths hubs, all over the country, working to spread best practice and drive up the quality of teaching, and our new core maths programme. There is no reason why children in England can’t do just as well in maths as those in Japan, Singapore and China - so these hubs will lead the system in delivering huge and sustainable change.
There’ll be sponsors of our maths and physics chairs - world-leading companies: UBS, Imagination Technologies, Nationwide Building Society, Tata Consulting, Telereal Trilium, RBS , Barclays, Hutchison Whampoa, BAE Systems, Lloyds, GlaxoSmithKline, Samsung, Goldman Sachs and Prudential.
The programme is attracting PhD graduates to become teachers and bring their top-level expertise into schools.
Together we can make Britain a maths powerhouse.
No subject is more crucial to this country’s economic competitiveness.
More than any other subject, maths and science can open doors to all sorts of exciting, rewarding careers.
That’s never been more true than right now. As technology has become ever more sophisticated, and transformed ever more industries and occupations, more and more jobs now demand maths and science skills - from fashion to farming, manufacturing to music.
These skills are vital to get our country’s businesses, and our national economy, growing.
We know that maths skills command highest earnings premium in the jobs market.
And we know that the OECD calls numeracy “the best protection against unemployment, low wages, and poor health” - and that more than two thirds of employers want both maths and science to be promoted more in schools.
OECD analysis suggests that if 15-year-olds in this country could increase their average performance by 25 PISA points - the equivalent of just over half a school year - the potential benefit to our economy would be something in the order of $6 trillion.
But we also know that the pipeline is broken. Far too many young people in this country give up maths and science at 16.
We currently have the lowest rate of maths participation among 16- to 18-year-olds in the OECD - just about a fifth.
In 2013 more than 580,000 young people took maths at GCSE but only 82,000 people took it at A level.
But in Japan, Korea and Finland, all young people study maths to 18; in France, Germany, Massachusetts and British Columbia, it’s the vast majority.
And our young people will need to compete against their peers around the world for jobs, university places, for every opportunity. We can’t allow them to fall behind.
So we need to give our 16- to 18-year-olds this message. Maths and science can open more doors than they might realise - and give them the best possible start to the brightest possible future.
We are radically reforming our maths curriculum and qualifications to match the best worldwide.
Our maths hubs will be working with academics from Shanghai Normal University and NCETM to bring over the Asian-style mastery approach to maths - the approach which has already helped countries in East Asia and beyond to reach the top of the tables.
They’ll also host the Shanghai Teacher Exchange - sending English teachers out to Shanghai, the highest-performing region in the world, to show off the best of British and to see Chinese teaching techniques in action, then welcoming up to 60 teachers from Shanghai to share their knowledge and expertise with teachers here, providing masterclasses for both pupils and students.
This work will give English pupils a deeper understanding of maths. But they also need to learn it for longer.
By 2020, we want the overwhelming majority of young people to study maths to 18, going from the bottom of that table to the top.
That’s why we’re making sure that young people who don’t get at least a C in maths GCSE at the age of 16 continue to study the subject until 18 - and reforming the maths A Level, working with Ofqual and top universities, to make it more challenging and stretching.
We’re also funding Cambridge University to develop an advanced maths curriculum for A level students so they are ready for rigorous degree courses.
But at the moment, a huge segment of the cohort - about 40% - get a good grade in maths GCSE , but drop maths at 16.
Maybe their timetable is too full; maybe they didn’t feel there was a maths option for them. Either way, it adds up to this result. More than 200,000 students every year are missing out.
And they’re not just missing out on the fun and challenge of studying advanced maths for its own sake - they’re missing out on all the benefits that the subject brings. Their maths gets rusty; they lose confidence; they close down career options before they’ve even started.
That’s why we’re creating the new option of core maths, aimed at non-specialists, to keep these young people studying maths after GCSE - deepen and strengthen their skills, keep their confidence, and their ambitions, sky high.
Brand new, exciting core maths qualifications will fill that gap - offering 16- to 18-year-olds a challenging, rigorous course, learning to use maths to solve real life problems.
The courses will build students’ competence and confidence in mathematical techniques like statistics, advanced calculation, financial maths and modelling - for example, learning how to build a financial model to understand an investment, analyse trends in population growth or calculate ways to improve a process.
The International Baccalaureate ( IB ) Mathematical Studies, respected by universities and employers, can be the core.
These are the sort of techniques needed in all sorts of careers, from marketing to manufacturing, computing to nursing. Importantly, core maths qualifications will also count as the maths element of the Tech Bacc, the mark of achievement in vocational education - which will be available for first teaching in September 2015.
We’ve already seen this model work with the IB Career-related Certificate and IB Diploma
From September almost 200 schools and colleges have asked to deliver these qualifications - a year earlier than planned.
That means that more than 5,000 young people who would otherwise have given up maths to 18 will be continuing the subjects - and reaping the benefits.
These schools are the pioneers - and their experience, their enthusiasm, will be crucial as we roll out core maths across the whole country.
IB have made their course available to non- IB schools.
So I’d like to thank all the teachers and leaders who are going to be the first to try this out - and to wish them all the very best of luck for the year ahead.
This is a big - and exciting - change. It could transform the whole landscape of post-16 education in this country - and could give thousands of young people a much better start to adult life.
But that “could” won’t turn into a “will” unless schools and colleges are ready and raring to deliver core maths properly.
So I’d like to thank all of you here today for your help in supporting schools and colleges to make core maths a success.
In particular, my thanks go to Mick Blaylock and the team at CfBT for helping to establish the Core Maths Support Programme in the first place.
Your work, and the work of the support programme, will be crucial in helping us make core maths the norm for many, many more young people in the future.
This is the start of something big. When England can move from a place where it’s considered cool to say “I’m rubbish at maths” to a country where young people think, not “shall I do maths?”, but “what maths shall I study?”.
We want every young person to leave full-time education with an advanced maths qualification, and all the skills and benefits that brings.
That’s what core maths can achieve - and that’s what we’re all working together to do. So thank you again for your help - and let’s make core maths a huge success.

Prism Demo Application |
||
This sample demonstrates how to use JSR309 API to make a simple prism application in a SIP servlet.
The SIPServlet - PrismServlet - can handle SIP REGISTER, INVITE, MESSAGE, BYE request. During processing of these SIP requests, the servlet use JSR309 API to negotiate a session with media server and also implement TTS, ASR, recording functions.
PrismServlet handles SIP REGISTER, INVITE, BYE, MESSAGE requests.
For REGISTER message, PrismServlet maintains a mapping between the client's address-of-record and contact address so it can contact the client later. The mappings are stored in the servlet context.
PrismServlet always responds positively for all INVITE and BYE messages. During processing INVITE request, PrismServlet use JSR309 API to negotiate a session to media server for the incoming call. After the call is successfully established, the servlet use JSR309 API to play some prompt for user, and detect signals from user to implement IVR functions. The implemented IVR functions are as follows:
- Main menu: After the call is established, the application enters main menu. In the main menu, application will play some welcome message, and prompt user to say or press 1 to test TTS function, say or press 2 to test recording function.
- TTS function test: If user presses or says 1 in the main menu, the application enters TTS function test. The application will send a prompt Instance Message to user, then the user will see a pop-out Instance Message window. If user send messages, the application will use the JSR309 API to play back the messages for user.
- Record function test: If user presses or says 2 in the main menu, the application enters recording function test. The application will prompt user it is going to start record after a beep, then user can say something to record. User can stop the recording by pressing 4, after the recording is stopped, the application will play back the recorded voice.
For more details, please see source codes.
Please follow the steps below to run a X-Lite with this sample:
Prism application is installed under $INSTALL_DIR/apps by default. You can re-install it by copy prism directory (or prism.sar) into $INSTALL_DIR/apps directory. Start Prism Server if you haven't.
- Startup and Configure your X-Lite (or other compatible SIP Clients).
- Open X-Lite 3.0 or later. For Mac Snow Leopard user, X-Lite 4.0 (beta and above) must be used.
- On the display board, write click and select "SIP Acount Settings...".
- On the SIP Accounts panel, click Add....
- Type the User Details and Domain Proxy as follow.
- Then click OK.
- Register your X-Lite to "Prism" application.
- Start Prism Application Server as user guide.
- Start X-Lite,and it will register to the container.
- Use your X-Lite to interact with "Prism" application.
- Click the right arrow and right click on the Group List,select "Add Contact...".
- On the "Add Contact" tab, select "Softphone" as the Type,type the name: prism, and then click OK.
- Right click on the "prism" ,and select "Call".
- you will see the call is established successfully. The application will play some prompt, follow the prompt, you can try the IVR functions now. For implemented IVR functions, see Understanding the Sample

How to connect a model to a flexible support
Table of Contents
1 Method 1 - Connection of multiple Mass-Spring-Damper systems
1.1 Mass-Spring-Damper representation
Let's consider a simple Mass-Spring-Damper system that is on top of an other mecanical system (see figure 1).
Figure 1: Basic Mass-Spring-Damper
Second Newton's laws of motion on the mass \(m_i\):
\[ m_i \ddot{x} = k_i (x_{i-1} - x_i) + c_i (\dot{x_{i-1}} - \dot{x_i}) + g_i + f_{i+1} \]
\[ m_i \ddot{x} + c_i \dot{x_i} + k_i x_i = c_i \dot{x_{i-1}} + k_i x_{i-1} + g_i + f_{i+1} \]
By doing a Laplace tranformation, we have:
\[ ( m_i s^2 + c_i s + k_i ) X_i = ( c_i s + k_i ) X_{i-1} + G_i + F_{i+1} \]
Finally:
\begin{equation} X_i = \frac{c_i s + k_i}{m_i s^2 + c_i s + k_i} X_{i-1} + \frac{1}{m_i s^2 + c_i s + k_i} G_i + \frac{1}{m_i s^2 + c_i s + k_i} F_{i+1} \end{equation}\[ X_i = T_{x_{i-1} \rightarrow x_i} X_{i-1} + T_{g_i \rightarrow x_i} G_i + T_{f_{i+1} \rightarrow x_i} F_{i+1} \]
With:
\begin{equation*} \begin{cases} T_{x_{i-1} \rightarrow x_i} &= \frac{c_i s + k_i}{m_i s^2 + c_i s + k_i}\\ T_{g_i \rightarrow x_i} &= \frac{1}{m_i s^2 + c_i s + k_i}\\ T_{f_{i+1} \rightarrow x_i} &= \frac{1}{m_i s^2 + c_i s + k_i} \end{cases} \end{equation*}Now, let's express the force \(f_i\):
\[ f_i = k_i (x_i - x_{i-1}) + c_i (\dot{x_i} - \dot{x_{i-1}}) \]
By doing a Laplace tranformation, we have:
\[ F_i = (X_i - X_{i-1}) ( c_i s + k_i ) \]
And finally by reinjecting \(X_i\) into the last equation, we have the following equation:
\begin{equation} F_i = \frac{- m_i s^2 (c_i s + k_i)}{m_i s^2 + c_i s + k_i} X_{i-1} + \frac{c_i s + k_i}{m_i s^2 + c_i s + k_i} G_i + \frac{c_i s + k_i}{m_i s^2 + c_i s + k_i} F_{i+1} \end{equation}\[ F_i = T_{x_{i-1} \rightarrow f_i} X_{i-1} + T_{g_i \rightarrow f_i} G_i + T_{f_{i+1} \rightarrow f_i} F_{i+1} \]
With:
\begin{equation*} \begin{cases} T_{x_{i-1} \rightarrow f_i} &= \frac{- m_i s^2 (c_i s + k_i)}{m_i s^2 + c_i s + k_i}\\ T_{g_i \rightarrow f_i} &= \frac{c_i s + k_i}{m_i s^2 + c_i s + k_i}\\ T_{f_{i+1} \rightarrow f_i} &= \frac{c_i s + k_i}{m_i s^2 + c_i s + k_i} \end{cases} \end{equation*}1.2 General representation
So we have a representation of the system with 3 inputs and 2 outputs (figure 2). This system is governed by the following equation:
\begin{equation} \begin{pmatrix} x_i \\ f_i \end{pmatrix} = \begin{pmatrix} T_{x_{i-1} \rightarrow x_i} & T_{g_i \rightarrow x_i} & T_{f_{i+1} \rightarrow x_i} \\ T_{x_{i-1} \rightarrow f_i} & T_{g_i \rightarrow f_i} & T_{f_{i+1} \rightarrow f_i} \end{pmatrix} \begin{pmatrix} x_{i-1}\\ g_i\\ f_{i+1} \end{pmatrix} \end{equation}
Figure 2: Input/Output representation of a system
That representation of a system with 3 inputs and 2 outputs can be generalized to any system as long as we have all the transfer functions \(T_{g_i\rightarrow x_i}\),…
1.3 System connection - General Case
1.4 System connection - 2 System case
Let's begin with a simple case of only 2 systems connected. Then, it is easy to generalized.
For now, let's ignore:
- \(f_0\) the force applied on the system bellow \(S_0\) (probably the ground)
- \(f_2\) the force applied one \(S_1\) because we suppose that there is no system of top of \(S_1\)
The connection of the 2 systems (figure 3) makes a connected system with 3 inputs (\(x_{-1} \quad g_0 \quad g_1\)) and 1 outputs \(x_1\).
Figure 4: Connect 2 systems
We can represent this system with a bloc diagram (figure 5).
Figure 5: Connect 2 systems - Bloc representation
Analytically:
\[ x_1 = T_{g_1 \rightarrow x_1}^1 g_1 + T_{x_0 \rightarrow x_1}^1 x_0 \]
\begin{align*} x_0 & = T_{g_0 \rightarrow x_0}^0 g_0 + T_{x_{-1} \rightarrow x_0}^0 x_{-1} + T_{f_1 \rightarrow x_0}^0 f_1\\ & = T_{g_0 \rightarrow x_0}^0 g_0 + T_{x_{-1} \rightarrow x_0}^0 x_{-1} + T_{f_1 \rightarrow x_0}^0 (T_{x_0 \rightarrow f_1}^1 x_0 + T_{g_1 \rightarrow f_1}^1 g_1) \end{align*}\[ x_0 = \frac{T_{g_0 \rightarrow x_0}^0}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1} g_0 + \frac{T_{x_{-1} \rightarrow x_0}^0}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1} x_{-1} + \frac{T_{f_1 \rightarrow x_0}^0 T_{g_1 \rightarrow f_1}^1}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1} g_1 \]
By reinjecting \(x_0\) into the first equation, we have an expression of the output \(x_1\) function of the 3 inputs \(x_{-1} \quad g_0 \quad g_1\).
\[ x_1 = (T_{g_1 \rightarrow x_1}^1 + \frac{T_{x_0 \rightarrow x_1}^1 T_{f_1 \rightarrow x_0}^0 T_{g_1 \rightarrow f_1}^1}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1}) g_1 + \frac{T_{x_0 \rightarrow x_1}^1 T_{g_0 \rightarrow x_0}^0}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1} g_0 + \frac{T_{x_0 \rightarrow x_1}^1 T_{x_{-1} \rightarrow x_0}^0}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1} x_{-1} \]
\[ x_1 = T_{g_1 \rightarrow x_1} g_1 + T_{g_0 \rightarrow x_1} g_0 + T_{x_{-1} \rightarrow x_1} x_{-1} \]
With:
\begin{equation*} \begin{cases} T_{g_1 \rightarrow x_1} &= T_{g_1 \rightarrow x_1}^1 + \frac{T_{x_0 \rightarrow x_1}^1 T_{f_1 \rightarrow x_0}^0 T_{g_1 \rightarrow f_1}^1}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1}\\ T_{g_0 \rightarrow x_1} &= \frac{T_{x_0 \rightarrow x_1}^1 T_{g_0 \rightarrow x_0}^0}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1}\\ T_{x_{-1} \rightarrow x_1} &= \frac{T_{x_0 \rightarrow x_1}^1 T_{x_{-1} \rightarrow x_0}^0}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1} \end{cases} \end{equation*}And now we have the analytical expression of the transfer functions of the connected system.
1.5 System connection - Example
Let's say that we have a flexible support \(S_0\). The only thing we know about this support is the relation between a force applied on top of it to its displacement: \(T_{f_1 \rightarrow x_0}^0\).
Know, we want to add a mass-spring-damper system on top of this flexible support. We would like to know the displacement of the mass-spring-damper system from a force applied to it, that is to say we want \(T_{g_1 \rightarrow x_1}\).
\[ T_{g_1 \rightarrow x_1} = T_{g_1 \rightarrow x_1}^1 + \frac{T_{x_0 \rightarrow x_1}^1 T_{f_1 \rightarrow x_0}^0 T_{g_1 \rightarrow f_1}^1}{1 - T_{f_1 \rightarrow x_0}^0 T_{x_0 \rightarrow f_1}^1} \]
\begin{equation*} \begin{cases} T_{x_0 \rightarrow x_1}^1 &= \frac{c_i s + k_i}{m_i s^2 + c_i s + k_i}\\ T_{g_1 \rightarrow x_1}^1 &= \frac{1}{m_i s^2 + c_i s + k_i}\\ T_{g_1 \rightarrow f_1}^1 &= \frac{c_i s + k_i}{m_i s^2 + c_i s + k_i}\\ T_{x_0 \rightarrow f_1}^1 &= \frac{- m_i s^2 (c_i s + k_i)}{m_i s^2 + c_i s + k_i} \end{cases} \end{equation*}We can calculate \(T_{g_1 \rightarrow x_1}\), and we obtain:
\begin{equation} T_{g_1 \rightarrow x_1} = \frac{T_{f_1 \rightarrow x_0}^0(c_1 s + k_1) + 1}{m_i s^s + c_1 s + k_1 + T_{f_1 \rightarrow x_0}^0 m_i s^s (c_1 s + k_1)} \end{equation}For instance if the flexible support is just a mass-spring-damper system with parameters \(m_0\) \(k_0\) \(c_0\):
\[T_{f_1 \rightarrow x_0}^0 = \frac{1}{m_0 s^2 + c_0 s + k_0}\]
And we finally have:
\begin{equation} T_{g_1 \rightarrow x_1} = \frac{(c_1 s + k_1) + (m_0 s^2 + c_0 s + k_0)}{(m_0 s^2 + c_0 s + k_0)(m_1 s^2 + c_1 s + k_1) + m_1 s^2 (c_1 s + k_1)} \end{equation}Let's verify this.
Figure 6: Dual mass-spring-damper system
We can applied the second law of Newton to the two masses:
\begin{align*} m_1 \ddot{x_1} & = c_1(\dot{x_0} - \dot{x_1}) + k_1 (x_0 - x_1) + g_1\\ m_0 \ddot{x_0} & = c_0(\dot{x_{-1}} - \dot{x_0}) + k_0 (x_{-1} - x_0) + c_1(\dot{x_1} - \dot{x_0}) + k_1 (x_1 - x_0) \end{align*}By doing a Laplace transform:
\begin{align*} (m_1 s^2 + c_1 s + k_1) x_1 & = (c_1 s + k_1) x_0 + g_1\\ (m_0 s^2 + c_0 s + k_0 + c_1 s + k_1) x_0 & = (c_0 s + k_0) x_{-1} + (c_1 s + k_1) x_1 \end{align*}The second equation gives us: \[ x_0 = \frac{c_0 s + k_0}{m_0 s^2 + c_0 s + k_0 + c_1 s + k_1} x_{-1} + \frac{c_1 s + k_1}{m_0 s^2 + c_0 s + k_0 + c_1 s + k_1} x_1 \]
And if we reinject \(x_0\) into the first equation, we have:
\[ (m_1 s^2 + c_1 s + k_1) x_1 = \frac{(c_1 s + k_1) (c_0 s + k_0)}{m_0 s^2 + c_0 s + k_0 + c_1 s + k_1} x_{-1} + \frac{(c_1 s + k_1) (c_1 s + k_1)}{m_0 s^2 + c_0 s + k_0 + c_1 s + k_1} x_1 + g_1 \]
Finally:
\[ \frac{m_1 s^2 (c_1 s + k_1) + (m_0 s^2 + c_0 s + k_0)(m_1 s^2 + c_1 s + k_1)}{m_0 s^2 + c_0 s + k_0 + c_1 s + k_1} x_1 = \frac{(c_1 s + k_1) (c_0 s + k_0)}{m_0 s^2 + c_0 s + k_0 + c_1 s + k_1} x_{-1} + g_1 \]
\[ x_1 = \frac{(c_1 s + k_1) (c_0 s + k_0) (m_0 s^2 + c_0 s + k_0 + c_1 s + k_1)}{(m_0 s^2 + c_0 s + k_0 + c_1 s + k_1) (m_1 s^2 + c_1 s + k_1) (m_1 s^2 (c_1 s + k_1) + (m_0 s^2 + c_0 s + k_0)(m_1 s^2 + c_1 s + k_1))} x_{-1} + \frac{m_0 s^2 + c_0 s + k_0 + c_1 s + k_1}{m_1 s^2 (c_1 s + k_1) + (m_0 s^2 + c_0 s + k_0)(m_1 s^2 + c_1 s + k_1)} g_1 \]
And we find \(T_{g_1 \rightarrow x_1}\) as before.
\begin{equation} T_{g_1 \rightarrow x_1} = \frac{(c_1 s + k_1) + (m_0 s^2 + c_0 s + k_0)}{(m_0 s^2 + c_0 s + k_0)(m_1 s^2 + c_1 s + k_1) + m_1 s^2 (c_1 s + k_1)} \end{equation}1.6 Matlab Implementation

2 Method 2 - How to connect a model on top of a flexible support
Figure 7: Flexible support
Second Newton's laws of motion on the mass \(m_i\):
\[ m_i \ddot{x_i} = k_i (x_s - x_i) + c_i (\dot{x_s} - \dot{x_i}) \]
After Laplace transformation:
\[ m_i s^2 x_i = (c_i s + k_i) (x_s - x_i) \]
Let's express \(F_s\):
\[ F_s = (c_i s + k_i) (x_i - x_s) \]
Figure 8: Flexible support Connection
In order to connect the system to the flexible support, we only need the transfer function between \(F_s\) and \(x_s\). This is usually done by identification.


LaDainian Tomlinson Thinks Cowboys Are Purposely Limiting Zeke To Help Dak Prescott Win MVP (VIDEO)
by Darrelle LincolnFor the second straight game, Ezekiel Elliott was held to under 50 yards rushing, but this time around, the team won without major production from him.
 That was proved on Sunday when Dallas threw the ball 46 times and ran it just 24 times, with six of those coming from Dak Prescott. Of the Cowboys’ 509 total yards, Prescott accounted for 444 through the air, while Zeke poured in just 45 yards rushing on 16 attempts.
LaDainian Tomlinson confidently believes the team is sacrificing Zeke’s gone to tilt the figurative field in Dak’s direction. The hall of fame RB presented his theory on Monday’s episode of Undisputed.
“When you have a young QB and offensive coordinator, you’re going to try to uplift that QB to be in the MVP race. So, naturally you’re not going to run the ball as much.”
Prescott is on pace to throw for 5,154 yards this season.

Chaos and confusion over Telford A&E as Boris comes to town
by Nick HumphreysFor a brief few minutes, it seemed years of campaigning to stop Telford's A&E department from being downgraded had finally paid off.
But hopes were quickly dashed after Boris Johnson said he would keep it open in his Conservative manifesto reveal ahead of the December General Election.
One of the buzz phrases the Prime Minister has used to describe a potential Jeremy Corbyn-led Labour government has been "chaos and confusion". But when questioned about the Telford A&E situation, it was the PM that left many scratching their heads.
When asked by the Shropshire Star about Mr Corbyn's recent pledge to scrap the Future Fit plans and keep full time A&E services at both Princess Royal Hospital in Telford and Royal Shrewsbury Hospital, Mr Johnson - who had been in fine form delivering his vision - seemed flustered.

- Future Fit to go ahead as planned despite confusion over Boris Johnson pledge
- The Conservative manifesto at a glance
He said on stage: "I'm looking at (Health Secretary) Matt Hancock here because I know that we have kept the A&E open, and we will ensure that it is open and I will absolutely insist on that and I know that Matt will be very happy to give you more details afterwards.We will certainly make sure that the A&E in Telford is kept open."
It was not initially clear whether the Prime Minister meant the A&E as it currently operates or the A&E local, however Mr Hancock soon confirmed there are no plans to change the Future Fit proposals which will leave Shropshire with one full A&E centre at the Royal Shrewsbury Hospital.
The consultant-led women's and children's services in Telford are also set to close under Future Fit.
Mr Hancock said: "We're going ahead with the plan and that's backing the decision that I published a month ago."
He was then asked what he would say to Telford residents who were disappointed by the downgrading of services. He said: "We're going to have investment in Telford and Shrewsbury. We can deliver that because of the extra funding the stronger economy will provide."
It was quite the blip from the PM who, while delivering his manifesto in Telford, appeared not to have been fully briefed about quite possibly the biggest issue facing its residents.
Potential
Around 100 protesters were also gathered behind metal fences at the venue with large banners, chanting "Boris Boris Boris, Out Out Out!"
But inside Mr Johnson enjoyed a rock star entrance to loud guitar music and rapturous applause from a room full of Tory MPs and party members, with the nation's media packed in at the side of the stage.
He launched confidently into his speech, and enjoyed laughter and applause when he joked that the nation would be "Corbyn-neutral by 2020" and spoke about being delighted to be in Telford, the heart of the industrial revolution.
He sought to characterise the election contest as a battle between "retrograde destructive socialism" under Labour and "sensible one nation Conservatism" under the Tories.
"In this manifesto there is a vision for the future in which we unite our country," he said.
"It is time to unleash the potential of our country and forge a new Britain."
"Get Brexit done and we can focus our hearts and our minds on the priorities of the British people.
We will invest millions more every week in science, in schools, in apprenticeships and in infrastructure, and control our debt at the same time."
The Conservatives chose Telford to launch the manifesto because it is one of the marginal seats. Lucy Allan won the seat by just 720 votes in the 2017 election.
Among the pledges were a triple tax lock - meaning no increases in income tax, National Insurance and VAT for five year, 20,000 more police officer, 50,000 more nurses and to bring back the PM's Brexit deal by Christmas.
Viewers at home who were playing Brexit Phrase Bingo will also have been pleased as they would have been able to tick off "dither and delay" and "Get Brexit Done" multiple times.
Commentators have described the manifesto as "steady as she goes" and that no rabbits were pulled out of the hat. Well, maybe one. But it was quickly stuffed back in.

ASG member arrested, 16 pipe bombs seized
by Zaida Delos ReyesGOVERNMENT forces arrested a member of Abu Sayyaf Group (ASG) and seized 16 pipe bombs identical to the bombs recovered from three slain suicide bombers in a follow-up operation, Wednesday afternoon in Indanan, Sulu.
This was confirmed yesterday by Joint Task Force Sulu (JTFS) spokesman Colonel Gerald Monfort.
Monfort identified the arrested ASG member as a certain alias Mang.
Alias Mang was arrested by JTF Sulu at around 6:10 p.m. in Barangay Kan Islam, Indanan, Sulu.
During his arrest, Mang revealed the location of locally assembled Improvised Explosive Device (IED) in their safehouse located at Barangay Paligue, Indanan, Sulu.
Troops from Philippine Army’s 41st Infantry Battalion immediately proceeded to the area and recovered 16 unrigged pipe bombs.
Monfort said the recovered pipe bombs were completely identical to the captured improvised explosives seized from the slain suicide bombers in Bgy. Kan Islam of the same municipality on Tuesday.
In line with this, Major General Corleto Vinluan Jr, the commander of JTF Sulu, reiterates his gratitude to the Tausug Community who provided timely information regarding the presence of the suicide bombers.
“The successful operations against the terrorists yesterday manifests that Sulu is no longer a haven for ASG bandits and foreign terrorists. With the strong support of the public, I am confident that we will end the problem with the ASG bandits and foreign terrorists in Sulu.” Vinluan said.

Task Description
The Really Simple Game
Company has just hired you. Your first programming
assignment is to write the “Shooting Stars” game.
This game is played on a 3 X 3 grid. Each location
on the grid has either a star or no star. An
asterisk represents a “star” and a period represents “no
star”. Each location on the grid is numbered 1-9,
going from left to right then top to bottom.
Grid Mapping
The object of the game is
to destroy all of the stars. To do this you shoot
star bombs at the grid, until there are no stars left.
You shoot a star bomb by typing the number of the grid
location. For any location you shoot at and the ones
adjacent vertically and horizontally, if there is a star
there it disappears and if there is no star there it
creates one. There is one star in the center for the
start of the game and looks like this:
...
.*.
...
If the first
character is a ‘5’, the resulting grid would look like:
.*.
*.*
.*.
Program Input
Any key character
can be input, but for a shot action all are ignored except
numeric digits 1-9.
Program Output
At the beginning of
the program print out “Welcome to Shooting Stars”, a blank
line, the initial star grid and then another blank line.
Do not print out any characters entered. Any
character entered that is not a 1-9 causes should be
ignored. After a valid numeric digit is input, print
out the new playing grid of stars with a blank line after
the star grid. If all stars have been destroyed,
then print out “You WIN!!!” and exit the program. |


Brunsbuttel lies on the northern bank of the River Elbe at the entrance to the Kiel Canal.
Position 53° 52' 59" N, 9° 7' 59" E.
This is a Port of Entry.
Good shelter in Alter Hafen (Old Port marina), which is a drying harbour with access 3hr +/- HW. It is just north of the locks.
A lock gives access to the canal and the Kanal-Yachthafen which is on the north side of the large Neue locks. It gets very crowded in season and due to the amount of canal traffic, it is not a peaceful berth, but useful.
There is a second yacht haven about half a mile further along the canal.
There are no moorings in the waiting area for the canal.
The town has a hospital, banks, post office, provision shops and a train station.

THE GREEN MILE A film review by Steve Rhodes Copyright 1999 Steve Rhodes RATING (0 TO ****): ***
With THE GREEN MILE, writer and director Frank Darabont (THE SHAWSHANK REDEMPTION) is back with his second Stephen King adaptation. This time it's the story of a gentle giant, John Coffey (Michael Clarke Duncan), who wouldn't harm a fly or a mouse -- more on the rodent later. Since he's a miracle worker who finds himself on death row, the story has a fairytale aspect to soften somewhat its many horrific execution scenes.
Like a beloved old uncle who drops by to tell you a story, Darabont rambles on and on, frequently letting himself get sidetracked. The result is a full three-hour movie that has no business being any longer than two. The viewers listen politely, trying not to fall asleep in the long, slow moments because the acting from the ensemble cast is superb. But with Darabont's proclivity for telegraphing every major plot turn way in advance, much of the drama is removed.
In a performance certain to garner him another best actor nomination, Tom Hanks plays Paul Edgecomb, the head guard of the death row section -- called the "Green Mile" -- of Cold Mountain Penitentiary, where John is sent to be fried in "Old Sparky" for supposedly killing and raping two young girls. Like the rest of the story, the director never allows for much doubt about the crime. (Why can't we have more mystery in our motion pictures?)
Set in 1935, the claustrophobic movie takes place mainly within a few rooms of a prison. David Tattersall's lush cinematography makes the few images outside the prison walls warmly nostalgic and the ones inside, when the miracles occur, magical.
So deeply religious is Paul that he constantly worries about how his actions will affect his own Judgment Day in heaven. More a minister than a guard to most of his inmates, he can deal effectively with troublemakers if the situation calls for it. Even if he gets awards for his performance, Hanks's work here is relatively middle of the road for him, which is a compliment to his talents. He doesn't even have to deliver his strongest work to justly be considered for an Academy Award.
A mouse named Mr. Jingles, who gets lots of screen time, steals scene after scene with his antics. The often funny script becomes charming as well when the little critter takes center stage to strut his stuff like the circus insects in A BUG'S LIFE.
"Sometimes the green mile seems so long," we are told in narration. And therein lies the problem. What should have been a great film turns into merely an enjoyable one because of its drawn-out length. The performances are admirable, but the characters aren't quite compelling. You end up respecting the show more than liking it. As it constantly tries to shock us with frightening images of people being electrocuted, we find ourselves becoming dispassionate observers. Sometimes intentional manipulation backfires as it does here. Being instructed to cry on cue every time they turn on the juice, this member of the audience just wasn't able to perform his role properly.
THE GREEN MILE runs a full hour too long at 3:03. It is rated R for violence, language and some sex-related material and would be acceptable for older teenagers.
The film opens nationwide in the United States on Friday, December 17. In the San Jose area it will be playing at the AMC and the Century theaters.

API Level: 10
Android 2.3.3 (GINGERBREAD_MR1
)
is a small feature release that adds several improvements
and APIs to the Android 2.3 platform.
For developers, the Android 2.3.3 platform is available as a downloadable component for the Android SDK. The downloadable platform includes an Android library and system image, as well as a set of emulator skins and more. To get started developing or testing against Android 2.3.3, use the Android SDK Manager to download the platform into your SDK.
API Overview
The sections below provide a technical overview of what's new for developers in 2.3.3, including new features and changes in the framework API since the previous version.
Near Field Communications (NFC)
Android 2.3.3 provides improved and extended support for NFC, to allow applications to interact with more types of tags in new ways.
A new, comprehensive set of APIs give applications read and write access to a wider range of standard tag technologies, including:
- NFC-A (ISO 14443-3A)
- NFC-B (ISO 14443-3B)
- NFC-F (JIS 6319-4)
- NFC-V (ISO 15693)
- ISO-DEP (ISO 14443-4)
- MIFARE Classic
- MIFARE Ultralight
- NFC Forum NDEF tags
The platform also provides a limited peer-to-peer communication protocol and API. Foreground Activities can use the API to register an NDEF message that will get pushed to other NFC devices when they connect.
Advanced tag dispatching now gives applications more control over how and
when they are launched, when an NFC tag is discovered. Previously, the platform
used a single-step intent dispatch to notify interested applications that a tag
was discovered. The platform now uses a four-step process that enables the
foreground application to take control of a tag event before it is passed to any
other applications (android.nfc.NfcAdapter.enableForegroundDispatch()
).
The new dispatch process also lets apps listen for specific tag content and
tag technologies, based on two new intent actions —
android.nfc.action.NDEF_DISCOVERED
and
android.nfc.action.TECH_DISCOVERED
.
The NFC API is available in the android.nfc
and
android.nfc.tech
packages. The key classes are:
NfcAdapter
, which represents the NFC hardware on the device.NdefMessage
, which represents an NDEF data message, the standard format in which "records" carrying data are transmitted between devices and tags. An NDEF message certain many NDEF records of different types. Applications can receive these messages fromNDEF_DISCOVERED
,TECH_DISCOVERED
, orTAG_DISCOVERED
Intents.NdefRecord
, delivered in anNdefMessage
, which describes the type of data being shared and carries the data itself.Tag
, which represents a tag scanned by the device. Multiple types of tags are supported, based on the underlying tag technology.TagTechnology
, an interface that gives applications access to tag properties and I/O operations based on the technologies present in the tag. For a full list of tag technologies supported in Android 2.3.3, seeandroid.nfc.tech
.
NFC communication relies on wireless technology in the device hardware, and
is not present in all Android devices. Android devices that do not support
NFC will return a null object when
getDefaultAdapter(Context)
is called, and
context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_NFC)
will return false
. The NFC API is always present, however, regardless of
underlying hardware support.
To use the NFC API, applications must request permission from the user by
declaring <uses-permission
android:name="android.permission.NFC">
in their manifest files.
Additionally, developers can request filtering on Google Play, such that
their applications are not discoverable to users whose devices do not support
NFC. To request filtering, add
<uses-feature android:name="android.hardware.nfc"
android:required="true">
to the application's manifest.
For more information, read the NFC developer guide.
Bluetooth
Android 2.3.3 adds platform and API support for Bluetooth nonsecure socket
connections. This lets applications communicate with simple devices that may not
offer a UI for authentication. See
createInsecureRfcommSocketToServiceRecord(java.util.UUID)
and
listenUsingInsecureRfcommWithServiceRecord(java.lang.String, java.util.UUID)
for more information.
Graphics
- A new
BitmapRegionDecoder
class lets applications decode a rectangle region from an image. The API is particularly useful when an original image is large and and the application only need parts of the image. - A new
inPreferQualityOverSpeed
field inBitmapFactory.Options
allows applications to use a more accurate but slightly slower IDCT method in JPEG decode. This in turn improves the quality of the reconstructed image.
Media framework
- A new
MediaMetadataRetriever
class provides a unified interface for retrieving frame and metadata from an input media file. MediaRecorder.AudioEncoder
andMediaRecorder.OutputFormat
include new fields for specifying AMR Wideband and AAC formats.
Speech recognition
The speech-recognition API includes new constants to let you manage voice
search results in new ways. Although the new constants are not needed for normal
use of speech recognition, you could use them to offer a different view of voice
search results in your application. For information, see RecognizerResultsIntent
.
API Level
The Android 2.3.3 platform delivers an updated version of the framework API. The Android 2.3.3 API is assigned an integer identifier — 10 — that is stored in the system itself. This identifier, called the "API Level", allows the system to correctly determine whether an application is compatible with the system, prior to installing the application.
To use APIs introduced in Android 2.3.3 in your application,
you need compile the application against the Android library that is provided in
the Android 2.3.3 SDK platform. Depending on your needs, you might
also need to add an android:minSdkVersion="10"
attribute to the <uses-sdk>
element in the application's
manifest. If your application is designed to run only on Android 2.3 and higher,
declaring the attribute prevents the application from being installed on earlier
versions of the platform.
For more information, read What is API Level?

Playing around with P5.js
I recently traveled out west to see an old buddy of mine. L.A. always seems to open my eyes up to new things. While there this time, I was introduced to Processing and P5.js. This might need a little bit of back story, but let me preface everything that follows by stating that I am a pretty boring dude. I like numbers and textbooks, but seeing what kind of visual stuff was easily possible left a lasting impression on me.
I (after watching a few youtube videos by Dan Shiffman working in Processing) was able to create the following purple rain example using the P5.js library. Initially, I was not really looking forward to working with Javascript, but having something THIS visual helped to get me excited about the entire process. Well…that, and some of the interactive stuff others were doing incorporating other peripherals like the Kinect.
Definitely a welcome change from staring at SQL databases all day.

This Week’s iPhone Pics (2/52)
This Week's iPhone Pics (1/52)
I’m not going to lie, this concept was stolen very strong inspired by Nuno Oliveira’s own “The Week in iPhone Photos” series. I’ve always wanted to start a photography project like a 365, but with my erratic shooting phases, the annoy particularity of film of being hard (harder, longer at least?) to process, I had never had the guts to undertake such a project. With this weekly stuff, I’m setting not limit be it a maximum or a minimum, as long as I’m getting something out on my blog every week. So here it is, my very first entry for my very first “This Week’s iPhone Pics”, TWiP for short.
Internet Ownage...
It never get’s old. I’m not going to lie, I appreciate getting into arguments with people over the internet (or over any other medium really), and I get kicks out of winning. How doesn’t. The latest to respond to my provocation was photographer, middle-aged man and twitter big-shot Scott Bourne. (Yes Scott, I’m still giving you link love, I hope we can still be friends!)
My First Rangefinder
When you’re a collector of fine things, whatever kind of things they may be, everything you take possession of in relation to your hobby has a certain importance, but some leave a stronger impression than others. I’ll take German cars for example. There’s the first car, that shitty old Volks that could barely do a commute without breaking down. It’s the spark that lights the ever-growing fire, and then next thing you know you’ve got 6 cars in your back yard that will remain in your memory forever, no matter if or when they get crushed up in a tiny little cube. The one that’s twice as old as you are. The one you bought for a fistful of quarters and a handshake off the old man down the street. The one you grossly overpaid.

We need your help to map the accessibility of the city. Problems such as lack of curb ramps make navigation more difficult for people with mobility impairments. Knowing where problems exist will help people plan their trip. Use our tool to walk through streets in Google Street View and report where the accessibility problems exist. We will use the data to visualize the city’s accessibility!
The collected accessibility data could be used in accessibility-aware map applications. For example, we could visualize whether one neighborhood has problems or not. The visualization allows a person with mobility impairment (e.g., a wheelchair user) to decide if they can go to their destination alone or they need someone to tag along to help them navigate inaccessible sidewalks.
Help us make sidewalks more accessible for everyone

We gave it our all…
It is with a heavy heart we announce that Everpix will be shutting down in the coming weeks.
We started this company two years ago with the goals of solving the photo mess and designing better ways for people to enjoy their memories. We are very proud of the work we’ve done—from the cutting-edge semantic analysis and syncing technology, right down to every pixel on our website and mobile apps.
We are grateful to our investors for giving us the opportunity to grow this project. But more importantly, we are so very thankful to the folks who supported us with subscriptions and feedback. You guys are the best.
It's frustrating (to say the least) that we cannot continue to work on Everpix. We were unable to secure sufficient funding in order to properly scale the business, and our endeavors to find a new home for Everpix did not come to pass. At this point, we have no other options but to discontinue the service.
We will email everyone soon in regards to refunds and exporting photos from Everpix—your memories are very important to us, and you can rest assured everyone on the team is working hard to ensure a simple and painless process.
Please read this document which explains the situation in more detail. Please don’t hesitate to reach out with questions or thoughts. Email us at<EMAIL_ADDRESS>or tweet @everpix.
Thank you, again. We'll miss you.

Plugin Information |
|---|
No information for the plugin 'regexemail' is available. It may have been removed from distribution. |
This plugin allows you to generate user email addresses from usernames.
RegEx Email plugin
This plugin allows you to generate user email addresses from usernames using regular expressions and Java format strings. Because there is no UI support for mail resolver configuration, you have to configure this plugin manually. That's done by creating a file named com.mtvi.plateng.hudson.regex.RegexMailAddressResolver.xml
and dropping it in the HUDSON_HOME
directory. Here's an example configuration file:
<?xml version='1.0' encoding='UTF-8'?> <com.mtvi.plateng.hudson.regex.Configuration> <userNameExpression>(.*) (.*)</userNameExpression><EMAIL_ADDRESS></com.mtvi.plateng.hudson.regex.Configuration>
As of version 0.2 of the plugin, you can specify multiple regular expression/email address pattern pairs:
<?xml version='1.0' encoding='UTF-8'?> <com.mtvi.plateng.hudson.regex.MultiConfiguration> <configurations> <com.mtvi.plateng.hudson.regex.Configuration> <userNameExpression>(.*) (.*) (.*)</userNameExpression><EMAIL_ADDRESS></com.mtvi.plateng.hudson.regex.Configuration> <com.mtvi.plateng.hudson.regex.Configuration> <userNameExpression>(.*) (.*)</userNameExpression><EMAIL_ADDRESS></com.mtvi.plateng.hudson.regex.Configuration> </configurations> </com.mtvi.plateng.hudson.regex.MultiConfiguration>
Note that the top-level element changes when you are using multiple configurations. Also note that if multiple regular expressions are potential matches (as in the case above), care must be taken to ensure the order is correct.
Version History
Version 0.3 (January 31, 2010)

First of all, there is no special format for a Rakefile. A Rakefile contains executable Ruby code. Anything legal in a ruby script is allowed in a Rakefile.
Now that we understand there is no special syntax in a Rakefile, there are some conventions that are used in a Rakefile that are a little unusual in a typical Ruby program. Since a Rakefile is tailored to specifying tasks and actions, the idioms used in a Rakefile are designed to support that.
So, what goes into a Rakefile?
Tasks are the main unit of work in a Rakefile. Tasks have a name (usually given as a symbol or a string), a list of prerequisites (more symbols or strings) and a list of actions (given as a block).
A task is declared by using the task
method.
task
takes a single parameter that is the name of the task.
task :name
Any prerequisites are given as a list (enclosed in square brackets) following the name and an arrow (=>).
task :name => [:prereq1, :prereq2]
NOTE: Although this syntax looks a little funky, it is legal Ruby. We are constructing a hash where the key is :name and the value for that key is the list of prerequisites. It is equivalent to the following ...
hash = Hash.new hash[:name] = [:prereq1, :prereq2] task(hash)
Actions are defined by passing a block to the task
method.
Any Ruby code can be placed in the block. The block may reference the task
object via the block parameter.
task :name => [:prereq1, :prereq2] do |t| # actions (may reference t) end
A task may be specified more than once. Each specification adds its prerequisites and actions to the existing definition. This allows one part of a rakefile to specify the actions and a different rakefile (perhaps separately generated) to specify the dependencies.
For example, the following is equivalent to the single task specification given above.
task :name task :name => [:prereq1] task :name => [:prereq2] task :name do |t| # actions end
Some tasks are designed to create a file from one or more other files. Tasks that generate these files may be skipped if the file already exists. File tasks are used to specify file creation tasks.
File tasks are declared using the file
method (instead of the
task
method). In addition, file tasks are usually named with
a string rather than a symbol.
The following file task creates a executable program (named
prog
) given two object files named a.o
and
b.o
. The tasks for creating a.o
and
b.o
are not shown.
file "prog" => ["a.o", "b.o"] do |t| sh "cc -o #{t.name} #{t.prerequisites.join(' ')}" end
It is common to need to create directories upon demand. The
directory
convenience method is a short-hand for creating a
FileTask that creates the directory. For example, the following
declaration …
directory "testdata/examples/doc"
is equivalent to …
file "testdata" do |t| mkdir t.name end file "testdata/examples" do |t| mkdir t.name end file "testdata/examples/doc" do |t| mkdir t.name end
The directory
method does not accept prerequisites or actions,
but both prerequisites and actions can be added later. For example …
directory "testdata" file "testdata" => ["otherdata"] file "testdata" do cp Dir["standard_data/*.data"], "testdata" end
Rake allows parallel execution of prerequisites using the following syntax:
multitask :copy_files => [:copy_src, :copy_doc, :copy_bin] do puts "All Copies Complete" end
In this example, copy_files
is a normal rake task. Its
actions are executed whenever all of its prerequisites are done. The big
difference is that the prerequisites (copy_src
,
copy_bin
and copy_doc
) are executed in parallel.
Each of the prerequisites are run in their own Ruby thread, possibly
allowing faster overall runtime.
If any of the primary prerequisites of a multitask have common secondary prerequisites, all of the primary/parallel prerequisites will wait until the common prerequisites have been run.
For example, if the copy_xxx
tasks have the following
prerequisites:
task :copy_src => [:prep_for_copy] task :copy_bin => [:prep_for_copy] task :copy_doc => [:prep_for_copy]
Then the prep_for_copy
task is run before starting all the
copies in parallel. Once prep_for_copy
is complete,
copy_src
, copy_bin
, and copy_doc
are
all run in parallel. Note that prep_for_copy
is run only
once, even though it is referenced in multiple threads.
The Rake internal data structures are thread-safe with respect to the multitask parallel execution, so there is no need for the user to do extra synchronization for Rake’s benefit. However, if there are user data structures shared between the parallel prerequisites, the user must do whatever is necessary to prevent race conditions.
Prior to version 0.8.0, rake was only able to handle command line arguments of the form NAME=VALUE that were passed into Rake via the ENV hash. Many folks had asked for some kind of simple command line arguments, perhaps using “–” to separate regular task names from argument values on the command line. The problem is that there was no easy way to associate positional arguments on the command line with different tasks. Suppose both tasks :a and :b expect a command line argument: does the first value go with :a? What if :b is run first? Should it then get the first command line argument.
Rake 0.8.0 solves this problem by explicitly passing values directly to the tasks that need them. For example, if I had a release task that required a version number, I could say:
rake release[0.8.2]
And the string “0.8.2” will be passed to the :release task. Multiple arguments can be passed by separating them with a comma, for example:
rake name[john,doe]
Just a few words of caution. The rake task name and its arguments need to be a single command line argument to rake. This generally means no spaces. If spaces are needed, then the entire rake + argument string should be quoted. Something like this:
rake "name[billy bob, smith]"
(Quoting rules vary between operating systems and shells, so make sure you consult the proper docs for your OS/shell).
Task argument values can also be picked up from the environment. For example, if the “release” task expected a parameter named “release_version”, then either
rake release[0.8.2]
or
RELEASE_VERSION=0.8.2 rake release
or, alternatively
rake release RELEASE_VERSION=0.8.2
will work. Environment variable names must either match the task parameter exactly, or match an all-uppercase version of the task parameter.
NOTE: A variable declared within a rake command will not persist in the environment:
$ export VALUE=old $ rake print_value VALUE=new new $ rake print_value old
Parameters are only given to tasks that are setup to expect them. In order to handle named parameters, the task declaration syntax for tasks has been extended slightly.
For example, a task that needs a first name and last name might be declared as:
task :name, [:first_name, :last_name]
The first argument is still the name of the task (:name in this case). The next two arguments are the names of the parameters expected by :name in an array (:first_name and :last_name in the example).
To access the values of the parameters, the block defining the task behaviour can now accept a second parameter:
task :name, [:first_name, :last_name] do |t, args| puts "First name is #{args.first_name}" puts "Last name is #{args.last_name}" end
The first argument of the block “t” is always bound to the current task object. The second argument “args” is an open-struct like object that allows access to the task arguments. Extra command line arguments to a task are ignored. Missing command line arguments are picked up from matching environment variables. If there are no matching environment variables, they are given the nil value.
If you wish to specify default values for the arguments, you can use the with_defaults method in the task body. Here is the above example where we specify default values for the first and last names:
task :name, [:first_name, :last_name] do |t, args| args.with_defaults(:first_name => "John", :last_name => "Dough") puts "First name is #{args.first_name}" puts "Last name is #{args.last_name}" end
Tasks that use parameters have a slightly different format for prerequisites. Use the arrow notation to indicate the prerequisites for tasks with arguments. For example:
task :name, [:first_name, :last_name] => [:pre_name] do |t, args| args.with_defaults(:first_name => "John", :last_name => "Dough") puts "First name is #{args.first_name}" puts "Last name is #{args.last_name}" end
There is an older format for declaring task parameters that omitted the task argument array and used the :needs keyword to introduce the dependencies. That format is still supported for compatibility, but is not recommended for use. The older format may be dropped in future versions of rake.
Sometimes it is useful to manipulate tasks programmatically in a Rakefile.
To find a task object, use the :[]
operator on the
Rake::Task
.
For example, the following Rakefile defines two tasks. The :doit task simply prints a simple “DONE” message. The :dont class will lookup the doit class and remove (clear) all of its prerequisites and actions.
task :doit do puts "DONE" end task :dont do Rake::Task[:doit].clear end
Running this example:
$ rake doit (in /Users/jim/working/git/rake/x) DONE $ rake dont doit (in /Users/jim/working/git/rake/x) $
The ability to programmatically manipulate tasks gives rake very powerful meta-programming capabilities w.r.t. task execution, but should be used with caution.
When a file is named as a prerequisite, but does not have a file task defined for it, Rake will attempt to synthesize a task by looking at a list of rules supplied in the Rakefile.
Suppose we were trying to invoke task “mycode.o”, but no task is defined for it. But the rakefile has a rule that look like this …
rule '.o' => ['.c'] do |t| sh "cc #{t.source} -c -o #{t.name}" end
This rule will synthesize any task that ends in “.o”. It has a prerequisite a source file with an extension of “.c” must exist. If Rake is able to find a file named “mycode.c”, it will automatically create a task that builds “mycode.o” from “mycode.c”.
If the file “mycode.c” does not exist, rake will attempt to recursively synthesize a rule for it.
When a task is synthesized from a rule, the source
attribute
of the task is set to the matching source file. This allows us to write
rules with actions that reference the source file.
Any regular expression may be used as the rule pattern. Additionally, a proc may be used to calculate the name of the source file. This allows for complex patterns and sources.
The following rule is equivalent to the example above.
rule( /\.o$/ => [ proc {|task_name| task_name.sub(/\.[^.]+$/, '.c') } ]) do |t| sh "cc #{t.source} -c -o #{t.name}" end
NOTE: Because of a quirk in Ruby syntax, parenthesis are required on rule when the first argument is a regular expression.
The following rule might be used for Java files …
rule '.class' => [ proc { |tn| tn.sub(/\.class$/, '.java').sub(/^classes\//, 'src/') } ] do |t| java_compile(t.source, t.name) end
NOTE: java_compile
is a hypothetical method
that invokes the java compiler.
Any ruby file (including other rakefiles) can be included with a standard
Ruby require
command. The rules and declarations in the
required file are just added to the definitions already accumulated.
Because the files are loaded before the rake targets are evaluated, the loaded files must be “ready to go” when the rake command is invoked. This make generated dependency files difficult to use. By the time rake gets around to updating the dependencies file, it is too late to load it.
The Rake.import
command addresses this by specifying a file to
be loaded after the main rakefile is loaded, but before
any targets on the command line are invoked. In addition, if the file name
matches an explicit task, that task is invoked before loading the file.
This allows dependency files to be generated and used in a single rake
command invocation.
NOTE: Starting in Rake version
0.9.0, the top level import
command is deprecated and we
recommend using the scoped "Rake.import
" command mentioned
above. Future versions of Rake will drop
support for the top level import
command.
require 'rake/loaders/makefile' file ".depends.mf" => [SRC_LIST] do |t| sh "makedepend -f- -- #{CFLAGS} -- #{t.prerequisites} > #{t.name}" end Rake.import ".depends.mf"
If “.depends” does not exist, or is out of date w.r.t. the source files, a
new “.depends” file is generated using makedepend
before
loading.
Standard Ruby comments (beginning with “#”) can be used anywhere it is
legal in Ruby source code, including comments for tasks and rules. However,
if you wish a task to be described using the “-T” switch, then you need to
use the desc
command to describe the task.
desc "Create a distribution package" task :package => [ ... ] do ... end
The “-T” switch (or “–tasks” if you like to spell things out) will display
a list of tasks that have a description. If you use desc
to
describe your major tasks, you have a semi-automatic way of generating a
summary of your Rake file.
traken$ rake -T (in /home/.../rake) rake clean # Remove any temporary products. rake clobber # Remove any generated file. rake clobber_rdoc # Remove rdoc products rake contrib_test # Run tests for contrib_test rake default # Default Task rake install # Install the application rake lines # Count lines in the main rake file rake rdoc # Build the rdoc HTML Files rake rerdoc # Force a rebuild of the RDOC files rake test # Run tests rake testall # Run all test targets
Only tasks with descriptions will be displayed with the “-T” switch. Use “-P” (or “–prereqs”) to get a list of all tasks and their prerequisites.
As projects grow (and along with it, the number of tasks), it is common for task names to begin to clash. For example, if you might have a main program and a set of sample programs built by a single Rakefile. By placing the tasks related to the main program in one namespace, and the tasks for building the sample programs in a different namespace, the task names will not will not interfere with each other.
For example:
namespace "main" do task :build do # Build the main program end end namespace "samples" do task :build do # Build the sample programs end end task :build => ["main:build", "samples:build"]
Referencing a task in a separate namespace can be achieved by prefixing the
task name with the namespace and a colon (e.g. “main:build” refers to the
:build task in the main
namespace). Nested namespaces are
supported, so
Note that the name given in the task
command is always the
unadorned task name without any namespace prefixes. The task
command always defines a task in the current namespace.
File task names are not scoped by the namespace command. Since the name of
a file task is the name of an actual file in the file system, it makes
little sense to include file task names in name space. Directory tasks
(created by the directory
command) are a type of file task and
are also not affected by namespaces.
When looking up a task name, rake will start with the current namespace and attempt to find the name there. If it fails to find a name in the current namespace, it will search the parent namespaces until a match is found (or an error occurs if there is no match).
The “rake” namespace is a special implicit namespace that refers to the toplevel names.
If a task name begins with a “^” character, the name resolution will start in the parent namespace. Multiple “^” characters are allowed.
Here is an example file with multiple :run tasks and how various names resolve in different locations.
task :run namespace "one" do task :run namespace "two" do task :run # :run => "one:two:run" # "two:run" => "one:two:run" # "one:two:run" => "one:two:run" # "one:run" => "one:run" # "^run" => "one:run" # "^^run" => "rake:run" (the top level task) # "rake:run" => "rake:run" (the top level task) end # :run => "one:run" # "two:run" => "one:two:run" # "^run" => "rake:run" end # :run => "rake:run" # "one:run" => "one:run" # "one:two:run" => "one:two:run"
FileLists are the way Rake manages lists of files. You can treat a FileList as an array of strings for the most part, but FileLists support some additional operations.
Creating a file list is easy. Just give it the list of file names:
fl = FileList['file1.rb', file2.rb']
Or give it a glob pattern:
fl = FileList['*.rb']
Blocks may be specified with either a do
/end
pair, or with curly braces in Ruby. We strongly recommend using
do
/end
to specify the actions for tasks and
rules. Because the rakefile idiom tends to leave off parentheses on the
task/file/rule methods, unusual ambiguities can arise when using curly
braces.
For example, suppose that the method object_files
returns a
list of object files in a project. Now we use object_files
as
the prerequisites in a rule specified with actions in curly braces.
# DON'T DO THIS! file "prog" => object_files { # Actions are expected here (but it doesn't work)! }
Because curly braces have a higher precedence than
do
/end
, the block is associated with the
object_files
method rather than the file
method.
This is the proper way to specify the task …
# THIS IS FINE file "prog" => object_files do # Actions go here end
When issuing the rake
command in a terminal, Rake will look for a Rakefile in the current
directory. If a Rakefile is not found, it will search parent directories
until one is found.
For example, if a Rakefile resides in the project/
directory,
moving deeper into the project’s directory tree will not have an adverse
effect on rake tasks:
$ pwd /home/user/project $ cd lib/foo/bar $ pwd /home/user/project/lib/foo/bar $ rake run_pwd /home/user/project
As far as rake is concerned, all tasks are run from the directory in which the Rakefile resides.
Not all tasks need to be included in a single Rakefile. Additional rake
files (with the file extension “.rake
”) may be placed in
rakelib
directory located at the top level of a project (i.e.
the same directory that contains the main Rakefile
).
Also, rails projects may include additional rake files in the
lib/tasks
directory.

GOSPEL Matthew 12:1-8
A reading from the holy Gospel according to Matthew
At that time Jesus went through the grainfields on
the sabbath; his disciples were hungry, and they began
to pluck heads of grain and to eat. But when the Pharisees saw it, they said to
him, "Look, your disciples are doing what is not lawful to do on the sabbath." He said to them, "Have you not read what
David did, when he was hungry, and those who were with him: how he entered the
house of God and ate the bread of the Presence, which it was not lawful for him
to eat nor for those who were with him, but only for the priests? Or have you
not read in the law how on the sabbath the priests in
the temple profane the sabbath, and are guiltless? I tell you, something
greater than the temple is here. And if you had known what this means, 'I
desire mercy, and not sacrifice,' you would not have condemned the guiltless.
For the Son of man is lord of the sabbath."

Optimize Slider Weights ¶
You may want to explore the relationships between temporal variables and one of the scalar variables in a column of the Metadata Table. First, select a Metadata Table column header for the comparison from the dropdown list shown in Figure 20. This dropdown is above the Scatterplot in the upper right. Then click the icon, which will adjust the slider weights to generate a Scatterplot projection maximizing differences in the value range of the selected variable. The resulting slider weights indicate the relative importance of each temporal variable in the phenomenon described by the set of values in that Metadata Table column. Note that Metadata Table columns with string values can be selected here, but that those strings are changed to integers starting from 1, where each integer corresponds to a string value in the column, ordered alphabetically.
To provide some sense of what this function does, here is an example of the results for optimizing the point projection and slider values against the Annual Precipitation variable. Figure 21 shows the Scatterplot where all temporal variables are fully weighted with their slider values set to 1. The points are colored by their values for Annual Precipitation, where high values are dark gray and low values are white.
Figure 22 shows the adjusted slider values and point projections after the optimization. From the sliders that are visible in the figure, we can see that many temporal variables do not contribute to Annual Precipitation (i.e. their sliders are set to zero), while others display varying levels of influence. Mean Humidity (not shown) exerts the strongest influence, with its slider value set to one. Max Temperature and Min Dew Point also exert influence.
