Typed Actors
Akka Typed Actors is an implementation of the Active Objects pattern. Essentially turning method invocations into asynchronous dispatch instead of synchronous that has been the default way since Smalltalk came out.
Typed Actors consist of 2 "parts", a public interface and an implementation, and if you've done any work in "enterprise" Java, this will be very familiar to you. As with normal Actors you have an external API (the public interface instance) that will delegate method calls asynchronously to a private instance of the implementation.
The advantage of Typed Actors vs. Actors is that with TypedActors you have a static contract, and don't need to define your own messages, the downside is that it places some limitations on what you can do and what you can't, i.e. you can't use become/unbecome.
Typed Actors are implemented using JDK Proxies which provide a pretty easy-worked API to intercept method calls.
Note
Just as with regular Akka Untyped Actors, Typed Actors process one call at a time.
When to use Typed Actors
Typed actors are nice for bridging between actor systems (the “inside”) and non-actor code (the “outside”), because they allow you to write normal OO-looking code on the outside. Think of them like doors: their practicality lies in interfacing between private sphere and the public, but you don’t want that many doors inside your house, do you? For a longer discussion see this blog post.
A bit more background: TypedActors can easily be abused as RPC, and that is an abstraction which is well-known to be leaky. Hence TypedActors are not what we think of first when we talk about making highly scalable concurrent software easier to write correctly. They have their niche, use them sparingly.
The tools of the trade
Before we create our first Typed Actor we should first go through the tools that we have at our disposal, it's located in akka.actor.TypedActor.
//Returns the Typed Actor Extension
TypedActorExtension extension =
TypedActor.get(system); //system is an instance of ActorSystem
//Returns whether the reference is a Typed Actor Proxy or not
TypedActor.get(system).isTypedActor(someReference);
//Returns the backing Akka Actor behind an external Typed Actor Proxy
TypedActor.get(system).getActorRefFor(someReference);
//Returns the current ActorContext,
// method only valid within methods of a TypedActor implementation
ActorContext context = TypedActor.context();
//Returns the external proxy of the current Typed Actor,
// method only valid within methods of a TypedActor implementation
Squarer sq = TypedActor.<Squarer>self();
//Returns a contextual instance of the Typed Actor Extension
//this means that if you create other Typed Actors with this,
//they will become children to the current Typed Actor.
TypedActor.get(TypedActor.context());
Warning
Same as not exposing this of an Akka Actor, it's important not to expose this of a Typed Actor, instead you should pass the external proxy reference, which is obtained from within your Typed Actor as TypedActor.self(), this is your external identity, as the ActorRef is the external identity of an Akka Actor.
Creating Typed Actors
To create a Typed Actor you need to have one or more interfaces, and one implementation.
The following imports are assumed:
import akka.actor.TypedActor;
import akka.actor.*;
import akka.japi.*;
import akka.dispatch.Futures;
import docs.AbstractJavaTest;
import scala.concurrent.Await;
import scala.concurrent.Future;
import scala.concurrent.duration.Duration;
import java.util.concurrent.TimeUnit;
import java.util.List;

import java.util.Random;

}
Our example interface:
public interface Squarer {
// typed actor iface methods ...
}
Our example implementation of that interface:
class SquarerImpl implements Squarer {
private String name;
public SquarerImpl() {
this.name = "default";
}
public SquarerImpl(String name) {
this.name = name;
}
// typed actor impl methods ...
}
The most trivial way of creating a Typed Actor instance of our Squarer:
Squarer mySquarer =
TypedActor.get(system).typedActorOf(
new TypedProps<SquarerImpl>(Squarer.class, SquarerImpl.class));
First type is the type of the proxy, the second type is the type of the implementation. If you need to call a specific constructor you do it like this:
Squarer otherSquarer =
TypedActor.get(system).typedActorOf(
new TypedProps<SquarerImpl>(Squarer.class,
new Creator<SquarerImpl>() {
public SquarerImpl create() { return new SquarerImpl("foo"); }
}),
"name");
Since you supply a Props, you can specify which dispatcher to use, what the default timeout should be used and more. Now, our Squarer doesn't have any methods, so we'd better add those.
public interface Squarer {
void squareDontCare(int i); //fire-forget
Future<Integer> square(int i); //non-blocking send-request-reply
Option<Integer> squareNowPlease(int i);//blocking send-request-reply
int squareNow(int i); //blocking send-request-reply
}
Alright, now we've got some methods we can call, but we need to implement those in SquarerImpl.
class SquarerImpl implements Squarer {
private String name;
public SquarerImpl() {
this.name = "default";
}
public SquarerImpl(String name) {
this.name = name;
}
public void squareDontCare(int i) {
int sq = i * i; //Nobody cares :(
}
public Future<Integer> square(int i) {
return Futures.successful(i * i);
}
public Option<Integer> squareNowPlease(int i) {
return Option.some(i * i);
}
public int squareNow(int i) {
return i * i;
}
}
Excellent, now we have an interface and an implementation of that interface, and we know how to create a Typed Actor from that, so let's look at calling these methods.
Method dispatch semantics
Methods returning:
- void will be dispatched with fire-and-forget semantics, exactly like ActorRef.tell
- scala.concurrent.Future<?> will use send-request-reply semantics, exactly like ActorRef.ask
- akka.japi.Option<?> will use send-request-reply semantics, but will block to wait for an answer, and return akka.japi.Option.None if no answer was produced within the timeout, or akka.japi.Option.Some<?> containing the result otherwise. Any exception that was thrown during this call will be rethrown.
- Any other type of value will use send-request-reply semantics, but will block to wait for an answer, throwing java.util.concurrent.TimeoutException if there was a timeout or rethrow any exception that was thrown during this call. Note that due to the Java exception and reflection mechanisms, such a TimeoutException will be wrapped in a java.lang.reflect.UndeclaredThrowableException unless the interface method explicitly declares the TimeoutException as a thrown checked exception.
Messages and immutability
While Akka cannot enforce that the parameters to the methods of your Typed Actors are immutable, we strongly recommend that parameters passed are immutable.
One-way message send
mySquarer.squareDontCare(10);
As simple as that! The method will be executed on another thread; asynchronously.
Request-reply message send
Option<Integer> oSquare = mySquarer.squareNowPlease(10); //Option[Int]
This will block for as long as the timeout that was set in the Props of the Typed Actor, if needed. It will return None if a timeout occurs.
int iSquare = mySquarer.squareNow(10); //Int
This will block for as long as the timeout that was set in the Props of the Typed Actor, if needed. It will throw a java.util.concurrent.TimeoutException if a timeout occurs. Note that here, such a TimeoutException will be wrapped in a java.lang.reflect.UndeclaredThrowableException by the Java reflection mechanism, because the interface method does not explicitly declare the TimeoutException as a thrown checked exception. To get the TimeoutException directly, declare throws java.util.concurrent.TimeoutException at the interface method.
Request-reply-with-future message send
Future<Integer> fSquare = mySquarer.square(10); //A Future[Int]
This call is asynchronous, and the Future returned can be used for asynchronous composition.
Stopping Typed Actors
Since Akka's Typed Actors are backed by Akka Actors they must be stopped when they aren't needed anymore.
TypedActor.get(system).stop(mySquarer);
This asynchronously stops the Typed Actor associated with the specified proxy ASAP.
TypedActor.get(system).poisonPill(otherSquarer);
This asynchronously stops the Typed Actor associated with the specified proxy after it's done with all calls that were made prior to this call.
Typed Actor Hierarchies
Since you can obtain a contextual Typed Actor Extension by passing in an ActorContext you can create child Typed Actors by invoking typedActorOf(..) on that.
Squarer childSquarer =
TypedActor.get(TypedActor.context()).
typedActorOf(
new TypedProps<SquarerImpl>(Squarer.class, SquarerImpl.class)
);
//Use "childSquarer" as a Squarer
You can also create a child Typed Actor in regular Akka Actors by giving the UntypedActorContext as an input parameter to TypedActor.get(…).
Supervisor Strategy
By having your Typed Actor implementation class implement TypedActor.Supervisor you can define the strategy to use for supervising child actors, as described in Supervision and Monitoring and Fault Tolerance.
Receive arbitrary messages
If your implementation class of your TypedActor extends akka.actor.TypedActor.Receiver, all messages that are not MethodCall instances will be passed into the onReceive-method.
This allows you to react to DeathWatch Terminated-messages and other types of messages, e.g. when interfacing with untyped actors.
Lifecycle callbacks
By having your Typed Actor implementation class implement any and all of the following:
- TypedActor.PreStart
- TypedActor.PostStop
- TypedActor.PreRestart
- TypedActor.PostRestart
You can hook into the lifecycle of your Typed Actor.
Proxying
You can use the typedActorOf that takes a TypedProps and an ActorRef to proxy the given ActorRef as a TypedActor. This is usable if you want to communicate remotely with TypedActors on other machines, just pass the ActorRef to typedActorOf.
Lookup & Remoting
Since TypedActors are backed by Akka Actors, you can use typedActorOf to proxy ActorRefs potentially residing on remote nodes.
Squarer typedActor =
TypedActor.get(system).
typedActorOf(
new TypedProps<Squarer>(Squarer.class),
actorRefToRemoteActor
);
//Use "typedActor" as a FooBar
Typed Router pattern
Sometimes you want to spread messages between multiple actors. The easiest way to achieve this in Akka is to use a Router, which can implement a specific routing logic, such as smallest-mailbox or consistent-hashing etc.
Routers are not provided directly for typed actors, but it is really easy to leverage an untyped router and use a typed proxy in front of it. To showcase this let's create typed actors that assign themselves some random id, so we know that in fact, the router has sent the message to different actors:
@Test public void typedRouterPattern() {
try {
// prepare routees
TypedActorExtension typed = TypedActor.get(system);
Named named1 =
typed.typedActorOf(new TypedProps<Named>(Named.class));
Named named2 =
typed.typedActorOf(new TypedProps<Named>(Named.class));
List<Named> routees = new ArrayList<Named>();
routees.add(named1);
routees.add(named2);
List<String> routeePaths = new ArrayList<String>();
routeePaths.add(typed.getActorRefFor(named1).path().toStringWithoutAddress());
routeePaths.add(typed.getActorRefFor(named2).path().toStringWithoutAddress());
// prepare untyped router
ActorRef router = system.actorOf(new RoundRobinGroup(routeePaths).props(), "router");
// prepare typed proxy, forwarding MethodCall messages to `router`
Named typedRouter = typed.typedActorOf(new TypedProps<Named>(Named.class), router);
System.out.println("actor was: " + typedRouter.name()); // name-243
System.out.println("actor was: " + typedRouter.name()); // name-614
System.out.println("actor was: " + typedRouter.name()); // name-243
System.out.println("actor was: " + typedRouter.name()); // name-614
typed.poisonPill(named1);
typed.poisonPill(named2);
typed.poisonPill(typedRouter);
} catch (Exception e) {
//dun care
}
}
}
In order to round robin among a few instances of such actors, you can simply create a plain untyped router, and then facade it with a TypedActor like shown in the example below. This works because typed actors of course communicate using the same mechanisms as normal actors, and methods calls on them get transformed into message sends of MethodCall messages.
// prepare routees
TypedActorExtension typed = TypedActor.get(system);
Named named1 =
typed.typedActorOf(new TypedProps<Named>(Named.class));
Named named2 =
typed.typedActorOf(new TypedProps<Named>(Named.class));
List<Named> routees = new ArrayList<Named>();
routees.add(named1);
routees.add(named2);
List<String> routeePaths = new ArrayList<String>();
routeePaths.add(typed.getActorRefFor(named1).path().toStringWithoutAddress());
routeePaths.add(typed.getActorRefFor(named2).path().toStringWithoutAddress());
// prepare untyped router
ActorRef router = system.actorOf(new RoundRobinGroup(routeePaths).props(), "router");
// prepare typed proxy, forwarding MethodCall messages to `router`
Named typedRouter = typed.typedActorOf(new TypedProps<Named>(Named.class), router);
System.out.println("actor was: " + typedRouter.name()); // name-243
System.out.println("actor was: " + typedRouter.name()); // name-614
System.out.println("actor was: " + typedRouter.name()); // name-243
System.out.println("actor was: " + typedRouter.name()); // name-614

Burritozilla Full Stack
This application represents my first project in putting the full stack of web technologies together. The application will display burrito objects whose location depends on the state of a boolean variable. Burritos that are ready to eat will appear on the left-hand side of the page while burritos that have consumed will appear on the right-hand side. Since this is burrito paradise burritos can be moved from either column by pressing the associated button. It is also possible create your own burrito and choose which group to add it to.
Unwind Teamwork + Foundation CSS
Unwind marks the milestone of putting everything together and building an application with a small team. Communication, planning, and work delegation were necessary to complete the build. The goal of the build was to stitch together multiple third party APIs, become familiar with Zurb's Foundation, and get hands on experience building an application in a team team setting. The team consisted of three junior developers working over four days.
Weather Dashboard AJAX + API + Bootstrap CSS
This project represented an opportunity to hone my JQuery skills and learn to use AJAX to get data from a third party API. The goal was to be able to generate content on the page dynamically and populate it with data retrieved from an API. A practical application of these two learning objectives is a weather dashboard that will allow the user to find weather information in a city of interest. As a bonus objective previously searched cities are saved in local storage which allows user data persistence between sessions.
Daily Planner JQuery + Local Storage
This daily planner project was an exercise in using JQuery, local storage, and using a javascript library. The planner displays the current date and a list of time blocks that can have text assigned to them. Each time block is color-coded to indicate whether it is in the past, present, or future. By clicking on a time block the user can type in text which is then saved to local storage using the save button located on the right hand side of each time block. This allows the contents of each text box to be saved in the event the page is refreshed or the browser is closed. Finally a button located at the bottom of the screen allows the user to clear the contents of all the text boxes and reset local storage.

From The AGC to Smartphones and Beyond
Oct 6, 2018 10:56 · 705 words · 4 minute read
Today, space technology has evolved to an extent that mankind can envisage a future where space tourism could be a thing. In contrast, not even five decades ago, a single space expedition was a near to impossible task. The journey has been a historic one, much of which has been made possible by the power of modern computers, the foundation for which was laid in the 1960’s.
The Moon Shot
Computers played a fundamental role in the first Apollo mission, and then eventual moon landing. Despite the fact that NASA’s computers at that time were laugh-worthy by today’s standards, they were proper enough to guide humans across 356,000 km of space.
Apollo Guidance Computer
Apollo Guidance Computer (AGC), designed at MIT, provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft. Putting it simply, the AGC helped the astronauts to better control their spacecraft by passing in nouns and verbs as commands. To control the hardware, AGC had built-in machine code instructions using a compiler called Luminary.
On July 7, former NASA intern Chris Garry uploaded the entire AGC source code to github. The humorous nature of some code snippets and comments is noteworthy. The instructions for the master ignition burn is titled, BURN_BABY_BURN- -MASTER_IGNITION_ROUTINE, for example. There’s even and explanation for it,
Read more about it here.
The AGC might’ve guided man to the moon but honestly, it wasn’t particularly powerful. In fact, it ran on a 64 kB memory at an underwhelming 0.043 MHz. Our hand-held calculators are more equipped than that. (What?!)
How Far Have We Come?
Computers have come a long way since the first Apollo mission. Nowadays, as mentioned, even the simple pocket calculators that we use in our everyday life has more computing power than the computers which were used during the Apollo missions. Even our toasters are more equipped than the AGC which allowed the astronauts to control their spacecrafts.
To put things into perspective,
The iPhone 6 uses an Apple-designed 64 bit Cortex A8 ARM architecture composed of approximately 1.6 billion transistors. It operates at 1.4 GHZ and can process instructions at a rate of approximately 1.2 instructions every cycle in each of its 2 cores. That’s 3.36 billion instructions per second. Put simply, the iPhone 6’s clock is 32,600 times faster than the best Apollo era computers and could perform instructions 120,000,000 times faster. You wouldn’t be wrong in saying an iPhone could be used to guide 120,000,000 Apollo era spacecraft to the moon, all at the same time. […]
That’s an insane amount of power!
How Far Can We Get?
As it is evident, from digital cameras to Artificial Intelligence, computers have come a long way since then and remain instrumental in our journey to deep space exploration. It’s only a matter of time before Mars Bar goes from being something you could munch on to a go-to spot for the space tourists.
But space exploration goes beyond establishing colonies on alien planets and there would be many more challenges further down the line. One of them being the constraints of human body. The limitations of human body will remain the drag in our advance to the deep space and it is difficult to envision human travel beyond a certain threshold. Inventor Ray Kurzweil, offers an interesting solution to this puzzle.
Based on Moore’s Law, if the current trends continue, by 2030 computers would contain the equivalent number of circuits as there are neurons in the human brain. Assuming equivalence, it might just be possible to transfer human consciousness on to a computer chip which can then explore the uncharted territories of the universe, unconstrained by a human body as we know it. It might sound like something out of a science fiction novel, but once upon a time, so did space travel, laser beams, and talking machines.

The FRIDGE design is a final project of the CODE.ME course. I invite you to use, reproduce and improve ...


The aim of this project is to use the time-dependent Hartree-Fock method to model electronic systems subject to an intense semi-classical laser. We will study how these systems react when they are perturbed by an external field.
We start our analysis by considering time-independent Hartree-Fock theory, as much of the tools and formalism will be the same as in the time-dependent case. Consider the time-independent Schrödinger equation $$ \begin{align} \hat{H}\vert\Psi\rangle = E\vert\Psi\rangle, \label{_auto1} \end{align} $$
where \( \hat{H} \) is a time-independent Hamiltonian, \( \vert\Psi\rangle \) an eigenfunction of the Hamiltonian and \( E \) the corresponding eigenenergy. In Hartree-Fock theory we assume that the full many-body wavefunction \( \vert\Psi\rangle \) can be approximated well by a single Slater determinant. That is, $$ \begin{align} \vert\Psi\rangle = \vert\Phi\rangle = \vert\phi_1, \dots, \phi_N\rangle, \label{_auto2} \end{align} $$
where we label this Slater determinant by \( \vert\Phi\rangle \). In a coordinate representation this Slater determinant can be represented by $$ \begin{align} \Phi(x_1, \dots, x_N) = \langle x_1, \dots, x_N \vert \phi_1, \dots, \phi_N \rangle = \frac{1}{\sqrt{N!}} \begin{vmatrix} \phi_1(x_1) & \dots & \phi_1(x_N) \label{_auto3}\\ \vdots & \ddots & \vdots \label{_auto4}\\ \phi_N(x_1) & \dots & \phi_N(x_N) \end{vmatrix}, \label{_auto5} \end{align} $$
where the coordinates \( x_i \) contain both position and spin. Hartree-Fock is a method for finding the "best" such Slater determinant, that is, the single Slater determinant that will yield the lowest energy for the given Hamiltonian. We achieve this by finding the \emph{molecular orbitals} \( \vert\phi_i\rangle \) that minimizes the energy using the variational method. In Hartree-Fock it is the molecular orbitals that are the unknowns we are trying to find. More specifically, we use \emph{atomic orbitals} \( \vert\chi_{\alpha}\rangle \) as our initial guess, and the do a basis transformation $$ \begin{align} \vert\phi_j\rangle = \sum_{\alpha} C_{\alpha j}\vert\chi_{\alpha}\rangle. \label{_auto6} \end{align} $$
Thus, we are interested in finding the coefficients \( C_{\alpha j} \) such that we can transform from the known atomic orbitals \( \vert\chi_{\alpha}\rangle \) to the optimal molecular orbitals \( \vert\phi_j\rangle \).
Recall that we in time-indepedent Hartree-Fock theory approximate the true many-body wavefunction \( \vert\Psi\rangle \) by a single Slater determinant \( \vert\Phi\rangle \) containing the \( N \) occupied \emph{molecular orbitals} \( \vert\phi_j\rangle \) subject to the constraint that $$ \begin{align} \langle \phi_i \vert \phi_j \rangle = \delta_{ij}, \label{_auto7} \end{align} $$
that is, the orbitals are orthonormal. The expectation value of the Hamiltonian is then $$ \begin{align} \langle \Phi \vert \hat{H} \vert \Phi \rangle = \sum_{i} \langle \phi_i \vert \hat{h} \vert \phi_i \rangle + \frac{1}{2} \sum_{ij} \langle \phi_i \phi_j \vert \hat{u} \vert \phi_i \phi_j \rangle_{AS}, \label{_auto8} \end{align} $$
where the many-body Hamiltonian is given by $$ \begin{align} \hat{H} = \hat{h} + \hat{u}. \label{_auto9} \end{align} $$
Here \( \hat{h} \) is the one-body part of the Hamiltonian containing the kinetic energy and an external potential. The two-body part \( \hat{u} \) will contain the two-body interactions between the particles in the system. In our case these interactions will be the Coulomb interaction. We have labeled the \emph{anti-symmetric two-body matrix elements} by $$ \begin{align} \langle \phi_p \phi_q \vert \hat{u} \vert \phi_r \phi_s \rangle_{AS} \equiv \langle \phi_p \phi_q \vert \hat{u} \vert \phi_r \phi_s \rangle - \langle \phi_p \phi_q \vert \hat{u} \vert \phi_s \phi_r \rangle. \label{_auto10} \end{align} $$
By constructing the Lagrangian functional $$ \begin{align} \mathcal{L} &= \langle \Phi \vert \hat{H} \vert \Phi \rangle - \sum_{ij} \lambda_{ji} \left( \langle \phi_i \vert \phi_j \rangle - \delta_{ij} \right) \label{_auto11}\\ &= \sum_{i} \langle \phi_i \vert \hat{h} \vert \phi_i \rangle + \frac{1}{2} \sum_{ij} \langle \phi_i \phi_j \vert \hat{u} \vert \phi_i \phi_j \rangle_{AS} - \sum_{ij} \lambda_{ji} \left( \langle \phi_i \vert \phi_j \rangle - \delta_{ij} \right), \label{_auto12} \end{align} $$
where \( \lambda_{ji} \) are the Lagrange multipliers used to optimize the Lagrangian under the orthonormality constraint of the molecular orbitals.
We consider a system of electrons confined in a pure two-dimensional isotropic harmonic oscillator potential, with an idealized total Hamiltonian given by $$ \begin{equation} \label{eq:finalH} \hat{H}=\sum_{i=1}^{N} \left( -\frac{1}{2} \nabla_i^2 + \frac{1}{2} \omega^2r_i^2 \right)+\sum_{i < j}\frac{1}{r_{ij}}, \end{equation} $$ where natural units (\( \hbar=c=e=m_e=1 \)) are used and all energies are in so-called atomic units a.u. We will study systems of many electrons \( N \) as functions of the oscillator frequency \( \omega \) using the above Hamiltonian. The Hamiltonian includes a standard harmonic oscillator part $$ \begin{equation*} \hat{H}_0=\sum_{i=1}^{N} \left( -\frac{1}{2} \nabla_i^2 + \frac{1}{2} \omega^2r_i^2 \right), \end{equation*} $$ and the repulsive interaction between two electrons given by $$ \begin{equation*} \hat{H}_1=\sum_{i < j}\frac{1}{r_{ij}}, \end{equation*} $$ with the distance between electrons given by \( r_{ij}=\vert \boldsymbol{r}_1-\boldsymbol{r}_2\vert \). We define the modulus of the positions of the electrons (for a given electron \( i \)) as \( r_i = \sqrt{r_{i_x}^2+r_{i_y}^2} \).
The aim of this project is to develop a coupled cluster doubles (CCD) code, where \( 2p-2h \) excitations are included only.
We will start with a two-electron problem and compare our results to those of Taut, see reference [1] below.
The ansatz for the ground state is given by $$ \begin{equation*} \vert \Psi_0\rangle = \vert \Psi_{CC}\rangle = e^{\hat{T}} \vert \Phi_0\rangle = \left( \sum_{n=1}^{N} \frac{1}{n!} \hat{T}^n \right) \vert \Phi_0\rangle, \end{equation*} $$ where \( N \) represents the maximum number of particle-hole excitations and \( \hat{T} \) is the cluster operator defined as $$ \begin{align*} \hat{T} &= \hat{T}_1 + \hat{T}_2 + \ldots + \hat{T}_N \\ \hat{T}_n &= \left(\frac{1}{n!}\right)^2 \sum_{\substack{ i_1,i_2,\ldots i_n \\ a_1,a_2,\ldots a_n}} t_{i_1i_2\ldots i_n}^{a_1a_2\ldots a_n} a_{a_1}^\dagger a_{a_2}^\dagger \ldots a_{a_n}^\dagger a_{i_n} \ldots a_{i_2} a_{i_1}. \end{align*} $$ The energy is given by $$ \begin{equation*} E_{\mathrm{CC}} = \langle\Phi_0\vert \overline{H}\vert \Phi_0\rangle, \end{equation*} $$ where \( \overline{H} \) is a similarity transformed Hamiltonian $$ \begin{align*} \overline{H}&= e^{-\hat{T}} \hat{H}_N e^{\hat{T}} \\ \hat{H}_N &= \hat{H} - \langle\Phi_0\vert \hat{H} \vert \Phi_0\rangle. \end{align*} $$ The coupled cluster energy is a function of the unknown cluster amplitudes \( t_{i_1i_2\ldots i_n}^{a_1a_2\ldots a_n} \), given by the solutions to the amplitude equations $$ \begin{equation}\label{eq:amplitudeeq} 0 = \langle\Phi_{i_1 \ldots i_n}^{a_1 \ldots a_n}\vert \overline{H}\vert \Phi_0\rangle. \end{equation} $$ In order to set up the above equations, the similarity transformed Hamiltonian \( \overline{H} \) is expanded using the Baker-Campbell-Hausdorff expression, $$ \begin{equation}\label{eq:bch} \overline{H}= \hat{H}_N + \left[ \hat{H}_N, \hat{T} \right] + \frac{1}{2} \left[\left[ \hat{H}_N, \hat{T} \right], \hat{T}\right] + \ldots + \frac{1}{n!} \left[ \ldots \left[ \hat{H}_N, \hat{T} \right], \ldots \hat{T} \right] +\dots \end{equation} $$ and simplified using the connected cluster theorem $$ \begin{equation*} \overline{H}= \hat{H}_N + \left( \hat{H}_N \hat{T}\right)_c + \frac{1}{2} \left( \hat{H}_N \hat{T}^2\right)_c + \dots + \frac{1}{n!} \left( \hat{H}_N \hat{T}^n\right)_c +\dots \end{equation*} $$ We will discuss parts of the the derivation below.
We will now approximate the cluster operator \( \hat{T} \) to include only \( 2p-2h \) correlations. This leads to the so-called CCD approximation, that is $$ \hat{T}\approx \hat{T}_2=\frac{1}{4}\sum_{abij}t_{ij}^{ab}a^{\dagger}_aa^{\dagger}_ba_ja_i, $$ meaning that we have $$ \vert \Psi_0 \rangle \approx \vert \Psi_{CCD} \rangle = \exp{\left(\hat{T}_2\right)}\vert \Phi_0\rangle. $$ Inserting these equations in the expression for the computation of the energy we have, with a Hamiltonian defined with respect to a general reference vacuum $$ \hat{H}=\hat{H}_N+E_{\mathrm{ref}}, $$ with $$ \hat{H}_N=\sum_{pq}\langle p \vert \hat{f} \vert q \rangle a^{\dagger}_pa_q + \frac{1}{4}\sum_{pqrs}\langle pq \vert \hat{v} \vert rs \rangle a^{\dagger}_pa^{\dagger}_qa_sa_r, $$ we obtain that the energy can be written as $$ \langle \Phi_0 \vert \exp{\left(-\hat{T}_2\right)}\hat{H}_N\exp{\left(\hat{T}_2\right)}\vert \Phi_0\rangle = \langle \Phi_0 \vert \hat{H}_N(1+\hat{T}_2)\vert \Phi_0\rangle = E_{CCD}. $$ This quantity becomes $$ E_{CCD}=E_{\mathrm{ref}}+\frac{1}{4}\sum_{abij}\langle ij \vert \hat{v} \vert ab \rangle t_{ij}^{ab}, $$ where the latter is the correlation energy from this level of approximation of coupled cluster theory. Similarly, the expression for the amplitudes reads $$ \langle \Phi_{ij}^{ab} \vert \exp{\left(-\hat{T}_2\right)}\hat{H}_N\exp{\left(\hat{T}_2\right)}\vert \Phi_0\rangle = 0. $$ These equations can be reduced to (after several applications of Wick's theorem), for all \( i > j \) and all \( a > b \), $$ \begin{align} 0 = \langle ab \vert \hat{v} \vert ij \rangle + \left(\epsilon_a+\epsilon_b-\epsilon_i-\epsilon_j\right)t_{ij}^{ab}+\frac{1}{2}\sum_{cd} \langle ab \vert \hat{v} \vert cd \rangle t_{ij}^{cd}+\frac{1}{2}\sum_{kl} \langle kl \vert \hat{v} \vert ij \rangle t_{kl}^{ab}+\hat{P}(ij\vert ab)\sum_{kc} \langle kb \vert \hat{v} \vert cj \rangle t_{ik}^{ac} & \nonumber \\ +\frac{1}{4}\sum_{klcd} \langle kl \vert \hat{v} \vert cd \rangle t_{ij}^{cd}t_{kl}^{ab}+\hat{P}(ij)\sum_{klcd} \langle kl \vert \hat{v} \vert cd \rangle t_{ik}^{ac}t_{jl}^{bd}-\frac{1}{2}\hat{P}(ij)\sum_{klcd} \langle kl \vert \hat{v} \vert cd \rangle t_{ik}^{dc}t_{lj}^{ab}-\frac{1}{2}\hat{P}(ab)\sum_{klcd} \langle kl \vert \hat{v} \vert cd \rangle t_{lk}^{ac}t_{ij}^{db},& \label{eq:ccd} \end{align} $$ where we have defined $$ \hat{P}\left(ab\right)= 1-\hat{P}_{ab}, $$ where \( \hat{P}_{ab} \) interchanges two particles occupying the quantum numbers \( a \) and \( b \). The operator \( \hat{P}(ij\vert ab) \) is defined as $$ \hat{P}(ij\vert ab) = (1-\hat{P}_{ij})(1-\hat{P}_{ab}). $$ The single-particle energies \( \epsilon_p \) are normally taken to be Hartree-Fock single-particle energies. Recall also that the unknown amplitudes \( t_{ij}^{ab} \) represent anti-symmetrized matrix elements, meaning that they obey the same symmetry relations as the two-body interaction, that is $$ t_{ij}^{ab}=-t_{ji}^{ab}=-t_{ij}^{ba}=t_{ji}^{ba}. $$ The two-body matrix elements are also anti-symmetrized, meaning that $$ \langle ab \vert \hat{v} \vert ij \rangle = -\langle ab \vert \hat{v} \vert ji \rangle= -\langle ba \vert \hat{v} \vert ij \rangle=\langle ba \vert \hat{v} \vert ji \rangle. $$ The non-linear equations for the unknown amplitudes \( t_{ij}^{ab} \) are solved iteratively.
In order to develop a program, chapter 8 of the recent Lecture Notes in Physics (volume 936) is highly recommended as literature. All material is available from the source site. Example of CCD codes are available from the program site. These can be used to benchmark your own program.
To test that your matrix elements are set up correctly, when you read in these matrix elements in the CCD code, make sure that the reference energy from your Hartree-Fock calculations are reproduced.
The next step consists in rewriting the equations in terms of matrix-matrix multiplications and subdividing the matrix elements and operations in terms of two-particle configuration that conserve total spin projection and projection of the orbital momentum. Rewrite also the equations in terms of so-called intermediates, as detailed in section 8.7 of Lietz et al. This section gives a detailed description on how to build a coupled cluster code and is highly recommended.
Rerun your calculations for \( =2 \), \( N=6 \), \( N=12 \) and \( N=20 \) electrons using your optimal Hartree-Fock basis. Make sure your results from 2b) stay the same.
Calculate as well ground state energies for \( \omega=0.5 \) and \( \omega=0.1 \). Try to compare with eventual variational Monte Carlo results from other students, if possible.
Compare thereafter your serial code(s) with the speedup you get by parallelizing your code, running either OpenMP or MPI or both. Do you get a near \( 100\% \) speedup with the parallel version? Comment again your results and perform timing benchmarks several times in order to extract an average performance time.
Here follows a brief recipe and recommendation on how to write a report for each project.
The preferred format for the report is a PDF file. You can also use DOC or postscript formats or as an ipython notebook file. As programming language we prefer that you choose between C/C++, Fortran2008 or Python. The following prescription should be followed when preparing the report:


Why the Man City squad are convinced Leroy Sane will join Bayern Munich
Leroy Sane’s team-mates are ‘increasingly convinced’ that the winger is in his final season at Manchester City.
The German was the subject of two bids from Bayern Munich last summer but his knee injury in August ended the Bavarians’ hopes of signing him.
City’s initial diagnosis was that Sane would not return until late March, meaning he’d face a race against time to prove his fitness for Euro 2020.
But there is now optimism at the club that the winger could return in February to boost the side’s title bid.
Sane is a popular figure in the City dressing room but the Telegraph report that the squad feel his ‘head has been turned’ by Bayern and that it’s only a matter of time before he makes the move.
The winger has 18 months remaining on his current deal and will be down to just a year left next summer, when Bayern hope to sign him for a reduced fee.
Advertisement Advertisement
It’s felt that the 22-year-old is keen on a return to Germany and City are already said to be looking at replacements.
Real Sociedad’s Mikel Oyarzabal is believed to be the frontrunner and has admirers on City’s board, such as director of football Txiki Begiristain.

Wikipedia defines a bastion server as "a special purpose computer on a network specifically designed and configured to withstand attacks." For the purposes of this documentation, though, any server that you can ssh through to reach other servers will do. Using standard ssh and drush techniques, it is possible to make a two-hop remote command look and act as if the destination machine is on the same network as the source machine.
Site aliases can refer to Drupal sites that are running on remote machines simply including 'remote-host' and 'remote-user' attributes:
$aliases['internal'] = array( 'remote-host' => 'internal.company.com', 'remote-user' => 'wwwadmin', 'uri' => 'http://internal.company.com', 'root' => '/path/to/remote/drupal/root', );With this alias defintion, you may use commands such as `drush @internal status`, 'drush ssh @internal` and `drush rsync @internal @dev` to operate remotely on the internal machine. What if you cannot reach the server that site is on from your current network? Enter the bastion server.
If you have access to a server, bastion.company.com, which you can ssh to from the open internet, and if the bastion server can in turn reach the internal server, then it is possible to configure ssh to route all traffic to the internal server through the bastion. The .ssh configuratin file would look something like this:
In .ssh/config:
Host internal.company.com ProxyCommand ssh<EMAIL_ADDRESS>nc %h %pThat is all that is necessary; however, if the dev machine you are configuring is a laptop that might sometimes be inside the company intranet, you might want to optimize this setup so that the bastion is not used when the internal server can be reached directly. You could do this by changing the contents of your .ssh/config file when your network settings change -- or you could use drush.
First, make sure that you do not have any configuration options for the internal machine in your .ssh/config file. The next step after that is to identify when you are connected to your company intranet. I like to determine this by using the `route` command to find my network gateway address, since this is always the same on my intranet, and unlikely to be encountered in other places.
In drushrc.php:
# Figure out if we are inside our company intranet by testing our gateway address against a known value exec("route -n | grep '^0\.0\.0\.0' | awk '{ print $2; }' 2> /dev/null", $output); if ($output[0] == '<IP_ADDRESS>') { drush_set_context('MY_INTRANET', TRUE); }After this code runs, the 'MY_INTRANET' context will be set if our gateway IP address matches the expected value, and unset otherwise. We can make use of this in our alias files.
In aliases.drushrc.php:
if (drush_get_context('MY_INTRANET', FALSE) === FALSE) { $aliases['intranet-proxy'] = array( 'ssh-options' => ' -o "ProxyCommand ssh<EMAIL_ADDRESS>nc %h %p"', ); } $aliases['internal-server'] = array( 'parent' => '@intranet-proxy', 'remote-host' => 'internal.company.com', 'remote-user' => 'wwwadmin', ); $aliases['internal'] = array( 'parent' => '@internal-server', 'uri' => 'http://internal.company.com', 'root' => '/path/to/remote/drupal/root', );The 'parent' term of the internal-server alias record is ignored if the alias it references ('@intranet-proxy') is not defined; the result is that 'ssh-options' will only be defined when outside of the intranet, and the ssh ProxyCommand to the bastion server will only be included when it is needed.
With this setup, you will be able to use your site alias '@internal' to remotely operate on your internal intranet Drupal site seemlessly, regardless of your location -- a handy trick indeed.

Abstract: Training a learning algorithm is a costly task. A major goal of active learning is to reduce this cost. In this paper we introduce a new algorithm, KQBC, which is capable of actively learning large scale problems by using selective sampling. The algorithm overcomes the costly sampling step of the well known Query By Committee (QBC) algorithm by projecting onto a low dimensional space. KQBC also enables the use of kernels, providing a simple way of extending QBC to the non-linear scenario. Sampling the low dimension space is done using the hit and run random walk. We demonstrate the success of this novel algorithm by applying it to both artiﬁcial and a real world problems.

About Me
I was born and raised in Addis Ababa, Ethiopia. I have a bachelor degree in civil Engineer. I have been working as an office Engineer in a consulting firm for three months. I have also worked as a graduate soil engineer in a AAU university for almost 8 months. My hobby is wacthing soccer and basket ball games.
I am currently studying full stack web development at University of minnesota. I anticpate to be full stack web developer in 8 months. Actually this is my first project!


So after perusing my different news feeds and subreddits, I came across this interesting
blog post. It is a very curious read, and I highly recommend looking through it yourself. But to sum it up, a security consultant named Egor Homakov for a website called Sakurity found a vulnerability with Starbuck's card balance transfers. He mentioned a term "race condition", which he states is a common bug for websites with balances or vouchers. This "race condition" becomes a bug when certain events do not happen in the order the programmer intended. In the article he talks about his pseudocode and his thought processess. After a while of failed experimenting, he was able to eventually create 2 cards; his first card was the original card with $5, and the 2nd card was a newly generated card with a $15 value.
He went to a local Starbucks, tried out the cards, and was able to successfully use both cards. He contacted (or at least tried) Starbucks tech support, but states they never really got back to him about the bug he had found. Eventually a Starbucks official, apparently from Starbucks infosec team, responded to his query and instead of praising him and thanking him, told him that he had committed fraud.
Homakov states in his blog that he could have easily made millions off of this bug by creating different Starbucks credits online and selling them. But no, he decided to be a responsible human being, and instead of being praised by the company he tried to help, he got insulted.
Anyways, I thought it would be nice to share this post. As a new programmer who is still trying to find his way, this debugging news was quite intriguing. Until next time!

just go with "return 3.141592653589793" BECAUSE IT NEVER CHANGES!!!!

My opinions:
1. We don't want to actually recreate PHP. We want to make PHP functions available for javascript, so a function that returns Pi, should return the javascript representation of Pi. The same goes for sqrt(2).
2. I doubt that an increase in precision will bother anybody, or that a decrease will help anybody.
3. There is a more obvious type representation difference between PHP and javascript that is bothering a lot of people: associative arrays. In JS we need objects to do this. I would like to make all array functions in a way they can handle these objects next to the normal arrays, but of course we'll never make a new Array object which handles associative arrays as well. And that's basically what you're asking here: to create a new Number type, which behaves differently than the JS native one.
Could we and would we want to change the outcome of something like 1+pow(10, -15) ? I think not. (I haven't tested this for differences but you'll get the idea)

I guess similarly, shouldn't all numbers (e.g. square roots) be truncated to 14 digits?
Philip Peterson
on 2008-10-14 23:33:36
Since PHP defaults to float 14, shouldn't we use the PHP-standard value of pi, 3.1415926535898 ?


 It would become for you a little bland, methinks. This is how life is becoming stuck on a risperdal treadmill.
I got trapped amongst the mental health regime due to my parents demanding that I see a psych, after condemning my trying recreational drugs. I love most dopamine, serotonin, and phenylethylamine substances. I had stated plainly that I liked methamphetamine a bit, mushrooms alot, and when I had research chemicals sent to me (2cp and 5meo-dmt) my family all came down on me like a tonne of angry dirt.
So, I have a meeting with a shrink arranged for me, and I think the mention that I used speed, pot, and what not made him think I was a candidate. He orders that I be reviewed in a mental hospital. When in hospital a few chicks came on to me, I got labelled as inappropriate by the docs, I had a few interviews the outcome of which was that I was 'grandiose and amused' which somehow in some wierd strange incomprehensible to me and judgemental way proved that I had psychosis- hence the 50mg shots in the bum and 6 month community treatment order.
Now it is interesting to note they gave me a 3 months sickness claim, meaning I could have an allowance as they had deemed me unfit for work. The medication kept on coming after I was discharged, but after the 3 months I was back to independence. My beliefs had not changed a bit, I had less I wanted to share with others, I was suffering somnolence (sleeping for 12-15 hours a day), my empathy had trailed off to something vague and brittle and my desire to do anything about it was diminished moreso. I rationalised that patience is all I could rely on and the treatment order would be over soon enough.
For some reason the treatment order has been renewed, and renewed, and renewed, and is imminently set to be renewed once again. I know that I have anger about this, but the risperdal ensures that my emotions are shut tight in the cardboard box so to speak, and feeds me more shredded cardboard, which leaves me morose and sullen, and a bit sick.
The cost of a shot is in excess of $700. It is given fortnightly. 2 people are travelling 30 mins each way in a company car to administer it to me. Add the cost of wages and petrol. I have never paid for this. I really wonder how society is structured in that war, for instance, is so destructive yet makes big money, and in a similar fashion risperidone, which is so unpleasant and destructive to the appreciation of life, can be making money by its sheer distribution and implementation.
Let me just say I think the force is a sham and the outcomes insidious. Reduction in transmitter activity is akin to brain damage. The longer I'm stuck on this hampster wheel for no other reason than that I retain the right to take recreational drugs, the more I think Iím a victim of the argument of institution versus freedom. I do have a strong spiritual belief that all the bad stuff is temporary, and if I persevere in doing the right thing God will do an accounting and I will inherit what I really deserve.

Vim, shorthand for Vi IMproved, is a text editor with numerous configuration options and wide-ranging extensions that can be used to write Python code.
Vim's philosophy is that developers are fastest when they never take their hands off the keys. Even using the mouse is a detriment to the rate at which your thoughts can flow into code.
Vim has a language behind its commands. When a beginner is learning the editor she may feel like it is impossible to understand all the key commands. However, the commands stack together in a logical way so that over time the editor becomes predictable.
The Vimrc file is used to configure the Vim editor. A Vimrc file can range from nothing in it to very complicated with hundreds or thousands of lines of configuration commands.
Here's a simple example .vimrc file I use for Python development to get a feel for some of the configuration statements:
# enable syntax highlighting syntax on # the next 4 lines set tabs to have 4 spaces, autoindent when already # working with indented lines, expand tabs key presses to spaces and # move lines 4 spaces each time the >> or << commands are used set ts=4 set autoindent set expandtab set shiftwidth=4 # enable all Python syntax highlighting features let python_highlight_all = 1
The Vimrc file lives under the home directory of the user account running
Vim. For example, when my user account is 'matt', on Mac OS X my Vimrc
file is found at /Users/matt/.vimrc
. On Ubuntu Linux my Vimrc file
can be found within /home/matt/.vimrc
.
If the Vimrc file does not already exist, just create it within the user's home directory and it will be picked up by Vim the next time you start the program.
Vim Adventures is a cute, fun browser-based game that helps you learn Vim commands by playing through the adventure.
Learn Vim Progressively is a wonderful tutorial that follows the path I took when learning Vim: learn just enough to survive with it as your day-to-day editor then begin adding more advanced commands on top.
A vim Tutorial and Primer is an incredibly deep study in how to go from beginner to knowledgeable in Vim.
Vim as Your IDE discusses how to set up Vim for greater productivity once you learn the initial Vim language for using the editor.
Setting up Vim for Python has a well written answer on Stack Overflow for getting started with Vim.
Vim as a Language explains the language syntax and how you can build up over time to master the editor.
In Vim: revisited the author explains his on-again off-again relationship with using Vim. He then shows how he configures and uses the editor so it sticks as his primary code editting tool.
A Good Vimrc is a fantastic, detailed overview and opinionated guide to configuring Vim. Highly recommended for new and experienced Vim users.
Vim and Python shows and explains many Python-specific .vimrc options.

"Phillip is filling up his cup."
By Logan Davis
10/11/16
You walked in and wouldn't introduce yourself. Neck craned forward and hands uncomfortably pressed
against your sides like you were mimicking a tall bird. We couldn't stop staring at your bowl cut.
I am sorry.
 Never once did we not laugh at a joke of
yours, unless you were laughing to much at it to get to the punch line. You seemed addicted to
laughter, both yours and others.
I will always remember, clear as day, when you walked to the back
of a quiet classroom and poured yourself water:
"Phillip is filling up his cup."
You laughed hard enough that you needed an inhale.  You were a freak.
We were all freaks.  We didn't know that until later.
You left for district. You left us in Center. We didn't talk for years. I got updates periodically through
Bradley, but he was too strung out to recall what clean clothes looked like most of the time, or maybe his
parents missed a water bill. I don't know. But he left soon after you did, so I lost all contact with you.
I am sorry.
What happened? How did you choose to become an engineer? Where did you go to school? Why did you go to that
specific school? I don't know. I won't know. Why should I know? You left and I stayed. You made it out.
You made it out. You made it out.
  Why did we want to get out?
  You would turn to him with a blank stare of confusion and then throw another
pencil into a spinning ceiling fan because you were bored.
You were always bored. You never had enough work to do. Anything we were assigned you would have done before
teacher finished explaining the prompt, so you often did the wrong thing. You didn't redo it though, you
already did work.
My parents still have the picture of us from seventh grade. The picture where you stepped forward right before
it was taken. You did it to look taller than the rest of us; you just looked out of place. Sometimes people
say "I can't picture them as an adult" when young people die. I think you were always out of place.
I am sorry.


| Pango Reference Manual | ||||
|---|---|---|---|---|
| Top | Description |
#define PANGO_VERSION_ENCODE (major, minor, micro) #define PANGO_VERSION #define PANGO_VERSION_MAJOR #define PANGO_VERSION_MINOR #define PANGO_VERSION_MICRO #define PANGO_VERSION_STRING #define PANGO_VERSION_CHECK (major, minor, micro) int pango_version (void
); const char * pango_version_string (void
); const char * pango_version_check (int required_major
,int required_minor
,int required_micro
);
The capital-letter macros defined here can be used to check the version of Pango at compile-time, and to encode Pango versions into integers. The functions can be used to check the version of the linked Pango library at run-time.
#define PANGO_VERSION_ENCODE(major, minor, micro)
This macro encodes the given Pango version into an integer. The numbers
returned by PANGO_VERSION
and pango_version()
are encoded using this macro.
Two encoded version numbers can be compared as integers.
|
the major component of the version number |
|
the minor component of the version number |
|
the micro component of the version number |
#define PANGO_VERSION
The version of Pango available at compile-time, encoded using
PANGO_VERSION_ENCODE()
.
#define PANGO_VERSION_MAJOR 1
The major component of the version of Pango available at compile-time.
#define PANGO_VERSION_MINOR 30
The minor component of the version of Pango available at compile-time.
#define PANGO_VERSION_MICRO 1
The micro component of the version of Pango available at compile-time.
#define PANGO_VERSION_STRING "1.30.1"
A string literal containing the version of Pango available at compile-time.
#define PANGO_VERSION_CHECK(major,minor,micro)
Checks that the version of Pango available at compile-time is not older than the provided version number.
|
the major component of the version number |
|
the minor component of the version number |
|
the micro component of the version number |
int pango_version (void
);
This is similar to the macro PANGO_VERSION
except that
it returns the encoded version of Pango available at run-time,
as opposed to the version available at compile-time.
A version number can be encoded into an integer using
PANGO_VERSION_ENCODE()
.
Returns : |
The encoded version of Pango library available at run time. |
Since 1.16
const char * pango_version_string (void
);
This is similar to the macro PANGO_VERSION_STRING
except that
it returns the version of Pango available at run-time, as opposed to
the version available at compile-time.
Returns : |
A string containing the version of Pango library available at run time. The returned string is owned by Pango and should not be modified or freed. |
Since 1.16
const char * pango_version_check (int required_major
,int required_minor
,int required_micro
);
Checks that the Pango library in use is compatible with the
given version. Generally you would pass in the constants
PANGO_VERSION_MAJOR
, PANGO_VERSION_MINOR
, PANGO_VERSION_MICRO
as the three arguments to this function; that produces
a check that the library in use at run-time is compatible with
the version of Pango the application or module was compiled against.
Compatibility is defined by two things: first the version
of the running library is newer than the version
required_major.required_minor
.required_micro
. Second
the running library must be binary compatible with the
version required_major.required_minor
.required_micro
(same major version.)
For compile-time version checking use PANGO_VERSION_CHECK()
.
|
the required major version. |
|
the required minor version. |
|
the required major version. |
Returns : |
NULL if the Pango library is compatible with the
given version, or a string describing the version mismatch.
The returned string is owned by Pango and should not be modified
or freed. |
Since 1.16

Where did Pat come up with such a genius idea?
He first started crafting these fine cookies in small batches in his mountain cottage north of Snoqualmie falls, and people couldn't help but smell it for miles! Pat has brought that tradition to his now world famous store in Pikes Place Market, for all to enjoy.
We actually grind up real northwestern chinook and whatever else fishermen drag in from the sea each morning to make these delicious treats. The best part is, you can't even taste the fish! With such a chewy, satisfying texture, they have become a locally beloved pairing with a hot cup of Seattle's finest, and will help chase away those depressing rainy days.
The best part is they're packed with protein and yummy Omega-3 fish oils. MMMMMmmmmm!

Sensex climbs 300 points, touches record high powered by Reliance Industries gains
Sensex touched a new high on Wednesday by gaining over 300 points early morning. BSE S&P Sensex index touched a high of 40,800 points
Sensex touched a new high on Wednesday by gaining over 300 points early morning. BSE S&P Sensex index touched a high of 40,800 points riding high on the gains of Reliance Industries.
Nifty too soared past the 12,000 mark after gaining over 70 points.
Equity benchmark indices traded with a positive bias during early hours on Wednesday with Mukesh Ambani-led Reliance Industries being the star performer after gaining 3.8 per cent.
A day earlier, Reliance became the first Indian company to cross-market capitalisation of Rs 9.5 lakh crore after its stock rallied over 3 per cent intra-day to hit a fresh all-time high.
At 11 am, the BSE S&P Sensex was up by 314 points at 40,779 while the Nifty 50 edged higher by 71 points to 12,026. Sectoral indices at the National Stock Exchange were mixed with Nifty auto, financial service, FMCG and PSU bank in the red. But Nifty pharma was up by 1.4 per cent.
Among stocks, Reliance was up by 3.79 per cent at Rs 1,567 per share while IndusInd Bank gained by 3.2 per cent at Rs 1,437.50.
Pharma majors Sun Pharma, Dr Reddy's and Cipla were up by 1.9 per cent, 1.7 per cent and 0.6 per cent respectively. The other gainers included Larsen & Toubro, Coal India, Bharat Petroleum Corporation, Adani Ports and Tata Consultancy Services.
However, Bharti Infratel fell by 3.6 per cent. Britannia, Yes Bank, Eicher Motors and GAIL also traded in the negative zone.
Meanwhile, Asian shares stumbled amid conflicting messages on the US-China trade talks. Late Tuesday, US President Donald Trump had threatened to raise tariffs further if China does not agree to a deal that he liked.
The mood in share markets was subdued with MSCI's broadest index of Asia Pacific shares outside Japan off 0.7 per cent. Japan's Nikkei fell by 0.8 per cent and Shanghai blue chips by 0.3 per cent.

The DB2 DirectoryMany DB2 application developers are unaware that DB2 uses a second dictionary-like structure in addition to the DB2 Catalog. This is the DB2 Directory. Used for storing detailed, technical information about aspects of DB2's operation, the DB2 Directory is for DB2's internal use only. The DB2 Directory is composed of five "tables." These tables, however, are not true DB2 tables because they are not addressable using SQL. From here on, they are referred to as structures instead of tables. These structures control DB2 housekeeping tasks and house complex control structures used by DB2. See Figure 22.7 for a summation of the relationships between the DB2 Catalog, the DB2 Directory, and DB2 operations. The objects in the DB2 Directory can be listed by issuing the following command: -DIS DB(DSNDB01) SPACE(*) LIMIT(*) Figure 22.7. The DB2 Directory.A quick rundown of the information stored in the DB2 Directory is in the following sections. SCT02The SCT02 structure holds the skeleton cursor tables (SKCTs) for DB2 application plans. These skeleton cursor tables contain the instructions for implementing the access path logic determined by the DB2 optimizer. The BIND PLAN command causes skeleton cursor tables to be created in the SCT02 structure. Executing the FREE PLAN command causes the appropriate skeleton cursor tables to be removed from SCT02. When a DB2 program is run, DB2 loads the skeleton cursor table into an area of memory called the EDM Pool to enable execution of the SQL embedded in the application program. SPT01Similar to the skeleton cursor tables are skeleton package tables which are housed in the SPT01 DB2 Directory structure. The skeleton package tables contain the access path information for DB2 packages. The BIND PACKAGE command causes skeleton package tables to be created in the SPT01 structure. Executing the FREE PACKAGE command causes the appropriate skeleton package tables to be removed from the DB2 Directory. When running a DB2 program that is based on a plan with a package list, DB2 loads both the skeleton cursor table for the plan and the skeleton package tables for the packages into memory to enable execution of the SQL embedded in the application program. DBD01Database descriptors, or DBDs, are stored in the DBD01 DB2 Directory structure. A DBD is an internal description of all the DB2 objects defined within a database. DB2 uses the DBD as an efficient representation of the information stored in the DB2 Catalog for these objects. Instead of accessing the DB2 Catalog for DB2 object information, DB2 accesses the DBD housed in the DB2 Directory because it is more efficient to do so. The DBD in the DB2 Directory can become out of sync with the physical DB2 objects that it represents, but this is unlikely. If this does happen, you will encounter many odd and unexplainable abends. The situation can be corrected using the REPAIR DBD utility, which is covered in Chapter 32, "Backup and Recovery Utilities." Furthermore, the REPAIR DBD TEST DATABASE utility can be run to detect when a DBD is out of sync with the actual physical objects. SYSUTILXDB2 monitors the execution of all online DB2 utilities. Information about the status of all started DB2 utilities is maintained in the SYSUTILX DB2 Directory structure. As each utility progresses, the step and its status are recorded. Utility restart is controlled through the information stored in SYSUTILX. Note that this structure maintains information only for started DB2 utilities. There are two "tables" within the SYSUTILX tablespace: SYSUTIL and SYSUTILX. Each utility step consumes a separate row, or record, in SYSUTIL, and in SYSUTILX when the amount of information exceeds the capacity of SYSUTIL. When the utility finishes normally or is terminated, all information about that utility is purged from SYSUTIL and SYSUTILX. SYSLGRNXThe RBA ranges from the DB2 logs are recorded on SYSLGRNX for tablespace updates. When recovery is requested, DB2 can efficiently locate the required logs and quickly identify the portion of those logs needed for recovery. |

Lowry looking to end 2019 on a high
Cape Town - The Open champion Shane Lowry has his sights set on a strong finish to the 2019 Race to Dubai with the aim of becoming European No 1 for the first time in his career as he prepares for the Turkish Open.
The Irishman, who triumphed at Royal Portrush in July, is less than 700 points behind current Race to Dubai rankings leader Bernd Wiesberger but, with increased points on offer in the final three events of the season, there is still all to play for, starting at The Montgomerie Maxx Royal in Belek.
"It's my main goal over the next few weeks to perform as best as I can, it would be lovely if I got to the final 18 holes in Dubai with a chance to win the Race to Dubai. To be European No 1 would be really special and would add to the year I've had," said Lowry.
"I think it would be the icing on the cake. I'm going to give it my best shot but if I don't win it, I won't be too disappointed. I've had a decent year and I'd be pretty happy with what I've got at Christmas.
"To start the year with a win in Abu Dhabi at a Rolex Series event was huge - that gave me the confidence going forward. Outside of a Major, as a European Tour player it probably doesn't get much bigger. There are WGCs as well, but Rolex Series events are definitely up there."
Already a Rolex Series winner this year after securing the Abu Dhabi HSBC Championship in January, Lowry is going in search of a sixth European Tour title this week.
Returning to Turkey with happy memories from last year are Thomas Detry and Martin Kaymer.
Detry recorded his best finish in a Rolex Series event at Regnum Carya Golf & Spa Resort, as a back-nine blitz of five consecutive birdies saw him move to 15 under, two strokes behind defending champion Justin Rose who defeated Li Haotong in a play-off. Kaymer finished in a share of fifth last year.
At 66th and 71st on the Race to Dubai Rankings respectively, both players will be looking to secure their spots in the Nedbank Golf Challenge and DP World Tour Championship, Dubai.
Just the Top 60 and then 50 players available from the Race to Dubai Rankings will take part in the final two events of the season.

UAA Rocketry WordPress Theme
custom theme based on _s
|
Hi. I'm a starter theme called _s
, or underscores
, if you like. I'm a theme meant for hacking so don't use me as a Parent Theme. Instead try turning me into the next, most awesome, WordPress theme out there. That's what I'm here for.
My ultra-minimal CSS might make me look like theme tartare but that means less stuff to get in your way when you're designing your awesome theme. Here are some of the other more interesting things you'll find here:
inc/custom-header.php
that can be activated by uncommenting one line in functions.php
and adding the code snippet found in the comments of inc/custom-header.php
to your header.php
template.inc/template-tags.php
that keep your templates clean and neat and prevent code duplication.inc/extras.php
that can improve your theming experience.js/navigation.js
that makes your menu a toggled dropdown on small screens (like your phone), ready for CSS artistry. It's enqueued in functions.php
.layouts/
for a sidebar on either side of your content.style.css
that will help you to quickly get your design off the ground.If you want to keep it simple, head over to http://underscores.me and generate your _s
based theme from there. You just input the name of the theme you want to create, click the "Generate" button, and you get your ready-to-awesomize starter theme.
If you want to set things up manually, download _s
from GitHub. The first thing you want to do is copy the _s
directory and change the name to something else (like, say, megatherium
), and then you'll need to do a five-step find and replace on the name in all the templates.
(inside single quotations) to capture the text domain.
Search for
_sto capture all the function names.
Search for
Text Domain: _s` in style.css. _s
(with a space before it) to capture DocBlocks._s-
to capture prefixed handles.OR
and replace with:
'megatherium'
Search for:
_sand replace with:
megatherium_
Search for:
Text Domain: _sand replace with:
Text Domain: megatherium` in style.css. _s
and replace with: Megatherium
_s-
and replace with: megatherium-
Then, update the stylesheet header in style.css
and the links in footer.php
with your own information. Next, update or delete this readme.
Now you're ready to go! The next step is easy to say, but harder to do: make an awesome WordPress theme. :)
Good luck!
