This documentation is intended for people who want to develop new packages for Bee. A package is made of tasks and eggs. Tasks may be compared to functions that run in build files. Eggs generate new projects interactively with the user and are similar to Rails Scaffoldings.
The fast way to start developing a new package is to run the package egg with following command line:
bee -t package
This will ask you the package name:
$ b -t package --------------------------------------------------------------------- welcome -- This script will create a project for a bee package with sample task (in 'lib' directory) and template (in 'egg' directory). A unit test for the task is generated in 'test' directory. Generated build file has a target 'test' to run unit tests, a target 'gem' to generate a gem archive, a 'clean' target to clean generated files and a 'install' target to build and install gem. ---------------------------------------------------------------------- prompt -- Please answer following questions to generate the project: What is the project's name? [bee_hello]:
Here, accept default name (bee_hello) pressing ENTER. A new directory named bee_hello is created in current directory that contains the generated project. Sample task is generated in file lib/bee_task_hello.rb and is the source for following task sample. Sample egg is generated in the egg subdirectory.
If you think that your preferred piece of Ruby code you run in Bee is of interest for other users, you should probably make it a Bee task. This is a way to make it easy to run and distribute to other users.
Let's say you decide to write a Bee task from your greeting script. This must be written in a script named bee_task_hello.rb, where hello will be the package of your task. This naming scheme that starts with bee_task followed by the package name is necessary so that Bee is able to locate and load this script when a task with package hello is called in a build file.
This package will contain a single task named hello that will greet a user which name is passed as argument to the task. You could write this script as follows:
Your code must be embedded in a class Hello (because of the name you choose for your package) in Bee::Task module. This class must inherit Bee::Task::Package to be recognized as a Bee task.
In this class, you will declare a method named hello, the named of the task you want to expose. It will take the name you want to say hello to. These methods that code a given task must always take a single parameter that is the object resulting from the YAML parsing of task parameters. Thus, this parameter may be a string, a list, a hash or any other YAML type, depending on your task parameters. These parameters are processed before calling these methods so that property references are replaced with their values, but its up to you to check that parameter types are correct and output an appropriate error message if this is not the case. Note that you may code more than one task in a given package.
You may call this task with following build file:
Which will output, as expected:
Of course, you must put the Ruby script for your task somewhere in your Ruby path so that it can be found. The best way to distribute a Bee task is probably building a Ruby Gem. This is done by the build file generated by package egg, running target gem. This build file is also able to run unit tests in the generated test/tc_bee_task_hello.rb by running target test.
Tasks are self documented. To get help about a task foo.bar, simply type bee -k foo.bar and you get this task documentation on the terminal. This works also for tasks you write. Simply write this documentation as the method help. Ruby will parse this comment and print it on the standard output. This help should always describe your task parameters and provide a short sample, as in the example we've seen above. Install generated gem for the template project, typing bee install in the template project directory. When typing bee -k hello.hello, you get the following help page:
$ bee -k hello.hello ----------------------------------------------------------------- hello.hello -- Sample hello task that prints greeting message on console. - who: who to greet. Example - hello.hello: "World"
This feature is quite convenient for people who write build files and thus tasks coders should take care of properly documenting their tasks.
An egg is a script that the user launches to generate interactively a new project. This is very handy to quickly have a running project to start working with. We've seen above that there is an egg to generate a template project for a Bee packages.
In a nutshell, eggs are Bee build files that ask the user for pieces of information, such as the project name, and generate the template in a subdirectory.
Let's say we have just discovered the power of Ruby Gems and want to distribute our scripts packaged as ready to install gems. We could write an egg to generate template projects to start with.
The first thing to do is to write a sample project that we will package and customize in our egg. This sample project, named hello might look like this:
hello | +- build.yml | +- bin | | | +- hello | +- lib | +- hello.rb
Our script is hello.rb in the lib directory:
To start this script as a gem, we need a launching script named hello in bin directory. This script might look like this one:
Now we need a build file to package our gem. This build file has targets to generate the gem archive, install and uninstall it and to clean generated files. The following one will do the job:
Now that we have a sample project, we must turn it into a template, which means add parameters to customize it. Our script will stay the same except that we will replace the file name with the project's name along with an .rb extension while generating the target project. The launching script must be customized so that the name of the file to load matches the script name. We can do so making this file an ERB file (Embedded Ruby, that is a file containing Ruby expressions embedded in <%= expression %> tags). This ERB might be:
While processing this file, the expression <%= project_name %> will be replaced with the value of project_name Ruby variable, which in turn will have the value of property project_name of our build file.
Our build file must be customized the same way:
Now we have all necessary pieces and just have to write a build file to put them together. We will name this build file after the template name (which suggests what it does). In this example, we'll name it hello. Thus this build file will be named hello.yml and we will put all associated file within a directory named hello. All egg files live in a directory named egg in the package directory. This convention must be implemented so that Bee is able to find a given package in a gem named bee_<package> and the build file to generate the template in a directory egg/<name>.yml. Thus, the structure of the directory of our example package is the following:
bee_<package> | +- egg | +- hello.yml | +- hello | +- build.erb | +- launcher.erb | +- script.rb
The build file to generate the template might be:
This build file defines two properties: project_name and description which are quiet self descriptive. Property description is used to describe egg in command line help, thus it should always be defined so that users may obtain a description of the purpose of your eggs.
First target, named welcome, simply prints the description of the egg. Second target, named prompt, will ask the user for the project's name. Target generate will generate template project, copying the script and processig the launching script and the build file using ERB, which will inject project's name into these scripts. Note that before generating template project we check that it's directory doesn't already exists to prevent an accident, overwriting an existing directory. Last target, named customization prints a closing message to the user.
The best way to test our egg is to go in the egg directory and launch the build file typing bee -f hello.yml, to start our egg's build file. This would produce:
$ bee -f hello.yml --------------------------------------------------------------------- welcome -- This script will create a project for a Ruby script that might be distributed as a gem. Generated build file has a single target gem to generate the distribution gem. ---------------------------------------------------------------------- prompt -- Please answer following questions to generate the project: What is the project's name? [hello]: test -------------------------------------------------------------------- generate -- Generating project... Creating directory 'test' Creating directory 'test/bin' Creating directory 'test/lib' Processing ERB 'hello/build.erb' Copying 1 file(s) to 'test/lib/test.rb' Processing ERB 'hello/launcher.erb' --------------------------------------------------------------- customization -- Project has been generated in directory 'test'. Type 'bee -b' to print information about generated build file. Enjoy! ------------------------------------------------------------------------- all -- OK
As a result, we have a brand new customized template project in directory test (the name for the generated template we entered on prompt). This output is the one your user will see running your egg typing bee -t hello.hello.
Now that you have written your package hello, you can distribute it as a Ruby Gem. To generate the gem, type bee gem in your package directory. If your gem is distributed using RubyForge, your users can install this package with:
sudo gem install bee_hello
Else, you can distribute this gem and your users can install it locally typing:
sudo gem install --local build/bee_hello-0.0.1.gem
Then, they will be able to use your new tasks in their build files and generate template projects typing bee -t hello.hello.
Enjoy!


Week 1: Version Control and GitHub
October 26, 2015
This week I learned a lot more about the command line, and how to use Git and GitHub to manage my workflow and collaborate with others. There was a lot of emphasis on version control and why we would need to be mindful of version control while we were coding. I have used Git and GitHub before in my previous role as a data analyst, so I had some familiarity with these concepts. We use version control so that we can capture snapshots of our work at different times, in case we may need to go back and edit our previous work. This also allows us to collaborate better with others since we can locate exactly when we made certain changes and see how that interacts with other’s work. We also allow others to comment on our changes and make sure they are correct before we finalize them.
Git helps us track our changes in several ways. We can create branches that track a set of changes we are trying to make to accomplish a certain task, and group those together. We can create “commits,” which are a snapshot of our files and changes at a certain point in time. Further, we have a detailed record of exact dates when certain changes were made using git.
Git is a local version control system that lives on your computer whereas Github is a remote entity where people share their code so developers can see and edit each other’s work. Because GitHub allows developers to share and edit each other’s code, it is a useful place to store your code.

| MATLAB 文件帮助: cv.decomposeProjectionMatrix | 查看 cv.decomposeProjectionMatrix 的代码 | Index |
decomposeProjectionMatrix Decomposes a projection matrix into a rotation matrix and a camera matrix
[cameraMatrix,rotMatrix,transVect] = cv.decomposeProjectionMatrix(projMatrix)
[cameraMatrix,rotMatrix,transVect,S] = cv.decomposeProjectionMatrix(projMatrix)
The function computes a decomposition of a projection matrix into a calibration and a rotation matrix and the position of a camera.
It optionally returns three rotation matrices, one for each axis, and three Euler angles that could be used in OpenGL. Note, there is always more than one sequence of rotations about the three principle axes that results in the same orientation of an object, eg. see [Slabaugh]. Returned three rotation matrices and corresponding three Euler angules are only one of the possible solutions.
The function is based on cv.RQDecomp3x3

Quality Performances
The numbers of quality performances are presented for each race series and represent another measure by which different race series can be ranked. For example, which marathon has produced the most quality performances for men, summed over all the years each event has been held? This is a close battle between the London (ENG) and Fukuoka (JPN) Marathons. The Fukuoka Marathon has been around for a long time and for a number of years was the de facto world championship. London is known for its great depth of elite fields and currently sports the men's world record. These tables provide a convenient way to examine such factors.
Quality performances are defined as those meeting the ADR qualification standards. Quality performances are presented for the following categories according to race distance. The quality performance score is the sum of the totals for each category. This provides a measure of both quantity and quality since faster performances are counted more times. Only statistically valid performances are included.

on the radio
Everytime I change the radio station, something in the world changes…or rather, the world itself is different slightly…in that it is an entirely different world. Sorry, let me back up. My name’s Jake, and I am, I think, a fourth year graduate student at Rensselaer Polytechnic Institute studying quantum mechanics. Why the “I think” you ask? Right. Well, I inherited a radio from my grandfather on my 27th birthday with a note on top, saying:
Understanding is the journey to knowledge. To most, it is unattainable because it lies behind closed doors. My gift to you: this key. Enjoy your journey. Pop-Pop
He had died a few days before, and one of the main regrets I had was that I wasn’t there when he died. I read the note a few times after it was delivered to me, and then placed the radio on the right corner of my desk, originally tuned to 93.1 FM. It remained there for a few days and I’d almost forgotten about it until a few months ago.
It was a Saturday and I was starting some routine reading. The subject matter was starting to bore me, and as I tapped my pencil eraser tip on the desk, my eyes focused on the radio, which was merely a decorative piece until now. Reaching over, I rotated the channel knob a couple of notches to the right. Nothing happened, and I didn’t expect it to. No music and no news. The thing was busted. Shrug. I just started doing some homework.
A couple of hours later, I decided to stretch my legs outside. I opened the front door, stepped outside, and it wasn’t until I finished locking the door that I realized my surroundings. Wait. Where was I? Everything was different. My house was the same, but it was enveloped by older high-rise apartments. Venturing further from my house, my breaths became shorter.  As I walked down the block, shops crowded the city scene at the street level, each with signs written in a pictographic language, possibly Chinese. Above every store a hundred floors of apartment windows rested. While vendors appeared to be open, the roads and streets were sparsely littered with a few people in a rush, most of whom were too busy to notice me, all of whom were wearing masks, and all of whom looked Asian. I glanced towards my house halfway down the block. Whew, it was still there albeit severely out of place.
Someone bumped me, and I instinctively, I responded, “Excuse me, sorry.”  Then, he shouted something Chinese, and others stopped to stare at the spectacle. Feeling pretty uncomfortable as people started to approach me, I decided it was time to high-tail it out of there and run back into my house.
I slammed the door and looked through the peephole. Good, no one followed me. What was going on? What happened? After a few moments of unanswerable lines of questioning, I backtracked all the things that I’d done before deciding to take that fateful stroll. There had to be a connection with what was going on outside: what did I remember before all this started. After some experimentation, I reached the conclusion pretty quickly that the culprit was my radio. My radio had sent me to a different world. After slipping it back to 93.1, I was relieved as much as I’d ever been to step outside to a sunny Saturday morning in upstate New York.
Technically, my little excursion to an alternate reality was also upstate New York. At least that was and is my current hypothesis. You see, in quantum mechanics, there’s an interpretation that says that whatever can happen does happen. It’s just that it happens on different a worlds. Say that I have reached a fork in some road, and I decide to turn left. There’s an entirely different world out there where I had decided to turn right. Extended to every possible decision ever made, my field in physics calls this the “many worlds/universes interpretation”.
Apparently, my grandfather’s radio was a way to bridge the gap between worlds, and the FM channels index a subset of them somehow.
Over the next few months, I experimented with the dial on the radio. Sometimes the world that I opened my door to destroyed my perception of the possible. Other times, I felt sorry for the world’s inhabitants. Still other times, I couldn’t tell the difference from our world. In every case, the one constant was my house, and I was always the only one who ever inhabited it. That is, all of the worlds were like this except for the one indexed by channel 106.5 FM.
Last night, after taking a break from physics homework, I slowly turned the radio knob, click by click, to 106.5. I had been documenting each one of the worlds in a notebook, trying to find a pattern between them. While reaching for the notebook this time, all the hairs on my body instantly rose and stiffened. What was that? Quiet, Jake. Listen.
Someone was breathing heavily like they had asthma. I looked back towards my closed door. The lights outside in the hallway were off. I swore that I had turned them on before I had started studying. “Why are they off,” I whispered underneath my breath.
Foot steps. Closer. The creaks in the wood betrayed the person’s location, as did his breathing. As they reached my door, my heart pounded. The handle on the door started to rotate.
Snap out of it, Jake! I jerked around and twisted the knob on the radio hard left, keeping an eye on the handle of the door without looking at where I’d turned the radio. It had stopped and the lights were back on outside. I took a deep breath and put my attention back on the radio dial, currently set to 94.5. Okay, whew. Let’s flip this guy back to my home world.
“Unknown”, I wrote in the log of worlds in my notebook next to 106.5 FM with red ink. Out loud, I then murmured, “I need to take a break from this for a while,” and dropped my grandfather’s radio into the bottom drawer of my desk.
A few days passed by, but the magical radio weighed heavily on my mind.  I stayed in my room, finding relevant academic journal paper after paper on relevant physics principles that could explain my experiences.
I had stopped eating; it didn’t occur to me that I was hungry. At times, I found myself reaching down to pull out the bottom drawer fueled with the guiding push of suspense. When my consciousness caught up to me in these moments, I would rapidly pull my hand back in fear. I’d become isolated, and even my Ph.D. adviser had voiced some concern in my behavior.
He had called on the phone. After some pleasantries, he stated his mind while being considerate enough not to dig into my specific issues. “Look, Jake, I like you, but I have six other students to support. Your fellowship is almost up, and I know you might be going through some stuff.
“During my tenure at RPI, more brilliant minds have been felled by fear and emotion in pursuing world-class research. If I may, a scientist’s job is to pursue the truth. Thesis aside, it looks to me like you have two options. Stand still, or do something. Only one of those options will give you a resolution. You don’t have to tell me anything, Jake, but I’m rooting for you. Good luck.”
He hung up, and I was alone in my room again. For reasons that I can’t explain, I suddenly realized that my focus had been so single-minded. After my adviser called, my head started to clear. He was right.
Another thing I realized was that I smelled. I jumped in the shower and stayed there for half an hour, letting the steam clean my pores. After drying off and getting dressed, I returned to my room and took a deep breath before I opened the bottom drawer of my desk. I grabbed my grandfather’s radio, placed it on my desk, and turned the frequency knob to the right from 93.1 FM. I slowed as it neared my intended final channel: 106.1 FM, 106.3 FM, and then…106.5 FM.
With a full expectation of something spectacular to happen, I turned around, scanning from ceiling to floor. Then, I jumped about six feet into the air. My door was open, but that wasn’t what startled me. Standing in the middle of my room with a grin on his face was an older bald man, bespectacled, and leaning on his cane. It was my grandfather.
“Hello, Jacob. I’ve been expecting you.”
“Pop-pop. I’ve missed you. How is this possible?”
“My dear Jacob. You must have had an amazing number of adventures in other realms.”
“Yes, I knew no one in any of them. How are you alive, even in this world?”
“Not everything can be explained by a unifying theory of physics even if we did reach a set of equations that could do so. Don’t think too hard with your mind, Jacob.”
I ran over to him and gave him a hug.
“I can’t stay too long here, Jacob. I was just waiting to see you.”
“Where are we? We’re on another world in our multi-verse, right?”
“Not quite, my boy. Yes, I’d made this radio with the potential to visit many of other worlds that vibrate at different frequencies than ours, but this channel is special. It’s a channel that I found on my own. I never gave you an explanation.”
“You…are still dead?”
He nodded with a kind smile. “I’d like to think of it as I’m off to another adventure. I gave you the radio for you to explore and learn things that your world couldn’t teach you, but there was another part of the gift. This radio: it’s as much for you as it is for me because it gives me the chance to say goodbye.”
We talked and laughed for a few hours. I told him about RPI and some of the worlds that I’d been to. He told me some tricks about using the radio. And then, it was time. I held out my hand to shake his, and he just batted it away and hugged me. Then, he took my hand, put it on the knob, and said, “you’ll do great things, Jacob. Just remember the real world you came from, and remember to live your life there, no matter how much time you spend on others.”
With a proper introduction to the radio now, I turned the knob and begun a most educational multi-world lesson.


IP-based access is the default access method when accessing the service without login or a key.
A Key-based access requires inserting an identification key (a long alfa-numeric string) in the text box below.
An empty or wrong key will back up to IP-based access.
All access methods may set a limit to the number of requests per hour and their total number.
A value for the request limit equal to "n/a" means no access.
A value equal to "-1" means unlimited requests.


A 6-day trek through one of the most beautiful valleys of the ‘Grand Sud’, the Rose Valley (or M'goun Valley), nested at the foot of the High Atlas. The name refers to the colour of the mineral of which the mountains are made.
A 6-day trek through one of the most beautiful valleys of the ‘Grand Sud’, the Rose Valley (or M'goun Valley), nested at the foot of the High Atlas. The name refers to the colour of the mineral of which the mountains are made.
Arrival at the airport and transfer by minibus or 4WD via El kalâa mgouna (route of 1000 Kasbahs) to Boutaghrar, the starting point of our hike where we will meet the muleteers. Overnight stay in an auberge.
After breakfast we’ll start our trek in the direction of the village of Agouti, where we’ll continue our walk and enter the gorges of Agouti (3km of gorges) to reach the village of Almdoun. Almdoun is a very beautiful, vast plain with a few small hamlets. Overnight stay in tents.
Today we will gradually walk up from the plain and cross several Berber villages. Our next bivouac in Tighremt n’Tichki is set at a height of 2377m.
A steep path will lead us to the Aït Ahmed Pass (2990m), where we'll have a fantastic view on both sides of the mountains. We’ll descend on the other side to the confluence of 2 valleys: Ouililimt Valley and M'goun Valley. Overnight stay in tents near the ruins of an old kasbah.
Beautiful day of walking in the M'goun Valley through many villages, campsite in Imi Nirkt at the entrance of the M'goun Canyon.
Whole day of walking in the river through one of the most spectacular areas of southern Morocco, the M'goun Canyon. Overnight stay in tents or in an auberge.
On our last day of hiking we will enter the Rose Valley again, we will cross some pretty, authentic villages (Issoumar,…) to finish our trip in Boutaghrar. Transfer to Ouarzazate, overnight stay in a hotel.
Got to catch that airplane!


A Ruby port of the Doug Lea's jsr166e.ConcurrentHashMapV8 class version 1.59 available in public domain.
Original source code available here: gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/jsr166e/ConcurrentHashMapV8.java?revision=1.59
The Ruby port skips out the TreeBin
(red-black trees for use
in bins whose size exceeds a threshold).
A hash table supporting full concurrency of retrievals and high expected concurrency for updates. However, even though all operations are thread-safe, retrieval operations do not entail locking, and there is not any support for locking the entire table in a way that prevents all access.
Retrieval operations generally do not block, so may overlap with update
operations. Retrievals reflect the results of the most recently
completed update operations holding upon their onset. (More
formally, an update operation for a given key bears a
happens-before relation with any (non nil
) retrieval
for that key reporting the updated value.) For aggregate operations such as
+clear()+, concurrent retrievals may reflect insertion or removal of only
some entries. Similarly, the each_pair
iterator yields
elements reflecting the state of the hash table at some point at or since
the start of the each_pair
. Bear in mind that the results of
aggregate status methods including +size()+ and empty?
} are
typically useful only when a map is not undergoing concurrent updates in
other threads. Otherwise the results of these methods reflect transient
states that may be adequate for monitoring or estimation purposes, but not
for program control.
The table is dynamically expanded when there are too many collisions (i.e.,
keys that have distinct hash codes but fall into the same slot modulo the
table size), with the expected average effect of maintaining roughly two
bins per mapping (corresponding to a 0.75 load factor threshold for
resizing). There may be much variance around this average as mappings are
added and removed, but overall, this maintains a commonly accepted
time/space tradeoff for hash tables. However, resizing this or any other
kind of hash table may be a relatively slow operation. When possible, it is
a good idea to provide a size estimate as an optional :initial_capacity
initializer argument. An additional optional :load_factor constructor
argument provides a further means of customizing initial table capacity by
specifying the table density to be used in calculating the amount of space
to allocate for the given number of elements. Note that using many keys
with exactly the same hash
is a sure way to slow down
performance of any hash table.
## Design overview
The primary design goal of this hash table is to maintain concurrent
readability (typically method +[]+, but also iteration and related methods)
while minimizing update contention. Secondary goals are to keep space
consumption about the same or better than plain Hash
, and to
support high initial insertion rates on an empty table by many threads.
Each key-value mapping is held in a Node
. The validation-based
approach explained below leads to a lot of code sprawl because
retry-control precludes factoring into smaller methods.
The table is lazily initialized to a power-of-two size upon the first
insertion. Each bin in the table normally contains a list of +Node+s (most
often, the list has only zero or one Node
). Table accesses require
volatile/atomic reads, writes, and CASes. The lists of nodes within bins
are always accurately traversable under volatile reads, so long as lookups
check hash code and non-nullness of value before checking key equality.
We use the top two bits of Node
hash fields for control
purposes – they are available anyway because of addressing constraints. As
explained further below, these top bits are used as follows:
- 00 - Normal - 01 - Locked - 11 - Locked and may have a thread waiting for lock - 10 - +Node+ is a forwarding node
The lower 28 bits of each Node
's hash field contain a the
key's hash code, except for forwarding nodes, for which the lower bits
are zero (and so always have hash field == MOVED
).
Insertion (via +[]=+ or its variants) of the first node in an empty bin is
performed by just CASing it to the bin. This is by far the most common case
for put operations under most key/hash distributions. Other update
operations (insert, delete, and replace) require locks. We do not want to
waste the space required to associate a distinct lock object with each bin,
so instead use the first node of a bin list itself as a lock. Blocking
support for these locks relies
+Concurrent::ThreadSafe::Util::CheapLockable. However, we also need a
try_lock
construction, so we overlay these by using bits of
the Node
hash field for lock control (see above), and so
normally use builtin monitors only for blocking and signalling using
cheap_wait
/cheap_broadcast
constructions. See
+Node#try_await_lock+.
Using the first node of a list as a lock does not by itself suffice though: When a node is locked, any update must first validate that it is still the first node after locking it, and retry if not. Because new nodes are always appended to lists, once a node is first in a bin, it remains first until deleted or the bin becomes invalidated (upon resizing). However, operations that only conditionally update may inspect nodes until the point of update. This is a converse of sorts to the lazy locking technique described by Herlihy & Shavit.
The main disadvantage of per-bin locks is that other update operations on
other nodes in a bin list protected by the same lock can stall, for example

or mapping functions take a long time. However,
statistically, under random hash codes, this is not a common problem.
Ideally, the frequency of nodes in bins follows a Poisson distribution (en.wikipedia.org/wiki/Poisson_distribution)
with a parameter of about 0.5 on average, given the resizing threshold of
0.75, although with a large variance because of resizing granularity.
Ignoring variance, the expected occurrences of list size k are (exp(-0.5) *
pow(0.5, k) / factorial(k)). The first values are:
- 0: 0.60653066 - 1: 0.30326533 - 2: 0.07581633 - 3: 0.01263606 - 4: 0.00157952 - 5: 0.00015795 - 6: 0.00001316 - 7: 0.00000094 - 8: 0.00000006 - more: less than 1 in ten million
Lock contention probability for two threads accessing distinct elements is roughly 1 / (8 * elements) under random hashes.
The table is resized when occupancy exceeds a percentage threshold
(nominally, 0.75, but see below). Only a single thread performs the resize
(using field size_control
, to arrange exclusion), but the
table otherwise remains usable for reads and updates. Resizing proceeds by
transferring bins, one by one, from the table to the next table. Because we
are using power-of-two expansion, the elements from each bin must either
stay at same index, or move with a power of two offset. We eliminate
unnecessary node creation by catching cases where old nodes can be reused
because their next fields won't change. On average, only about
one-sixth of them need cloning when a table doubles. The nodes they replace
will be garbage collectable as soon as they are no longer referenced by any
reader thread that may be in the midst of concurrently traversing table.
Upon transfer, the old table bin contains only a special forwarding node
(with hash field MOVED
) that contains the next table as its
key. On encountering a forwarding node, access and update operations
restart, using the new table.
Each bin transfer requires its bin lock. However, unlike other cases, a
transfer can skip a bin if it fails to acquire its lock, and revisit it
later. Method rebuild
maintains a buffer of TRANSFER_BUFFER_SIZE
bins that have been skipped because of failure to acquire a lock, and
blocks only if none are available (i.e., only very rarely). The transfer
operation must also ensure that all accessible bins in both the old and new
table are usable by any traversal. When there are no lock acquisition
failures, this is arranged simply by proceeding from the last bin
(+table.size - 1+) up towards the first. Upon seeing a forwarding node,
traversals arrange to move to the new table without revisiting nodes.
However, when any node is skipped during a transfer, all earlier table bins
may have become visible, so are initialized with a reverse-forwarding node
back to the old table until the new ones are established. (This sometimes
requires transiently locking a forwarding node, which is possible under the
above encoding.) These more expensive mechanics trigger only when
necessary.
The traversal scheme also applies to partial traversals of ranges of bins (via an alternate Traverser constructor) to support partitioned aggregate operations. Also, read-only operations give up if ever forwarded to a null table, which provides support for shutdown-style clearing, which is also not currently implemented.
Lazy table initialization minimizes footprint until first use.
The element count is maintained using a
+Concurrent::ThreadSafe::Util::Adder+, which avoids contention on updates
but can encounter cache thrashing if read too frequently during concurrent
access. To avoid reading so often, resizing is attempted either when a bin
lock is contended, or upon adding to a bin already holding two or more
nodes (checked before adding in the x_if_absent
methods, after
adding in others). Under uniform hash distributions, the probability of
this occurring at threshold is around 13%, meaning that only about 1 in 8
puts check threshold (and after resizing, many fewer do so). But this
approximation has high variance for small table sizes, so we check on any
collision for sizes <= 64. The bulk putAll operation further reduces
contention by only committing count updates upon these size checks.

Internal versions of the insertion methods, each a little more complicated than the last. All have the same basic structure:
1. If table uninitialized, create 2. If bin empty, try to CAS new node 3. If bin stale, use new table 4. Lock and validate; if valid, scan and add or update
The others interweave other checks and/or alternative actions:
* Plain +get_and_set+ checks for and performs resize after insertion. * compute_if_absent prescans for mapping without lock (and fails to add if present), which also makes pre-emptive resize checks worthwhile.
Someday when details settle down a bit more, it might be worth some factoring to reduce sprawl.

The integral_mask
type is
the most basic mask type. It is used to abstract all masks back to a simple
integral type. This type is used similar to an integral_constant
type from the Boost.Type Traits library.
#include <boost/integer/integral_mask.hpp>
integral_mask
has the following
template signature:
namespace boost { template <typename T, T Value> struct integral_mask; } // end boost
All other mask types either derive directly or indirectly from this class.
The integral_mask
class inherits
from integral_constant
.

The implicit cast operator allows for simplicity, clairity of code. In the
above example mask()
could be replaced with mask::value
to achieve the same result. The same applies to all other bitwise operators.


Nadai is a video game review site, based on the tastes of PC gamers on windows and linux operating systems. The site reviews games in the slim genres of sports, first-person shooters and role-playing games - however reviews for more "vanilla" games could be found on the website in times to come - including classics from the 80's and 90's
The founding developers of the site wanted to distinguish the site from those with similar review content. As such, a user-interface that is simple to navigate was prioritised rather than over-elaborate tools and features. Our site gives gamers what they need in the moment - quick and valuable tips and information regarding the game they want to investigate.
The next time you want to play a game yet aren't willing to look at pointless paragraphs of incomprehensible babbling, be sure to visit our website!

IN THE HIGH COURT OF JHARKHAND AT RANCHI A.B.A. No. 2526 of 2013 Sanjay Mehta .... Petitioner(s) Versus State of Jharkhand ... Opposite Party Coram : HON'BLE MR. JUSTICE D.N.UPADHYAY For the petitioner (s): Mr. Deepak Kumar For the opposite party : Addl.P.P. 04.07.2013
Heard the learned counsel for the petitioner and the learned counsel for the State.
This is an application for anticipatory bail flied by the petitioner in connection with Ichak PS case No. 188 of 2012 for the offence registered under sections 379/411 of the Indian Penal Code, section 21 of the Mines & Minerals (Development & Regulation) Act,1957; section 54 of the Jharkhand Minor Mineral Concession Rules, 2004 and section 21 of the Pollution & Environment Control Act, 1982.
Present case has been instituted against crusher owners who have not taken 'No Objection Certificate' from Pollution Control Board and other departments and were found running their crushers. It is alleged that stone chips and boulders have also been recovered from the premises of some of the accused persons.
It is submitted that the petitioner was just going to stall crusher for which foundation work was going on. In anticipation that he would run crusher without no objection certificate and he would commit illegal mining, he has been implicated in the case.
Learned counsel for the State has opposed the prayer. Contention made on the learned counsel finds support from the FIR itself.
Considering above aspects of the matter, the petitioner above named is directed to appear/surrender before the court below within a period of three weeks positively from the date of this order and on his surrender, he shall be released on bail on furnishing bail bond of Rs.10,000/- (rupees ten thousand) with two sureties of the like amount each to the satisfaction of CJM, Hazaribagh, in connection with Ichak PS case No. 188 of 2012 ( GR No. 4126 of 2012) subject to the conditions laid down under section 438(2) Cr.P.C.

(You have already completed this quest.)


Quality Assurance¶
Back in Development Environment we suggested a common kind of project organization.
There can be a src
directory with the final application and a tests
directory
with the unit test cases.
This works out extremely well because a lot of Python tools expect a structure similar to this.
Because there are some variations, we need to include
export PYTHONPATH=src
pytest
Or, as an alternative, we can set this each time we execute the tests.
PYTHONPATH=src pytest
We don’t need to provide very many options to the pytest program because the default directory for
tests, tests
is what we set up for outselves.
In this chapter, we’ll look at several other parts of test automation:
Static Type Checking with mypy.
Static Code Quality Checks with pylint.
Code Formatting with black.
Test Coverage Analysis with coverage.
Test Automation suite with tox.
The idea behind this suite of tools it to show a number of common practices that can be applied to this application.
Static Type Checking¶
We’ve annotated all of the descriptions of classes and methods with type hints. These are relatively new to Python. The hints have no run-time impact; they’re used for static analysis of the code to provide confidence it’s likely to work. See http://mypy-lang.org for more information on this tool.
If it’s not already installed, the mypy tool can be installed with
conda install mypy
The tool is used like this:
mypy src/blackjack.py
The output will often include numerous nuanced issues where the type hints on a parameter to a method don’t precisely match the type hints on the return type of another method.
Some Common Problems¶
One of the more common problems is reconciling the subclass-superclass features with methods actually used. Python duck typing rules mean any object will be searched for the expected attribute, either instance variable or method. The mypy tool looks for evidence the attribute or method is likely to be present.
Consider the following class definition
11 class Wheel_RNG:
12 def __init__(self, bins: List[Bin], rng: random.Random=None) -> None:
13 self.bins = bins
14 self.rng = rng or random.Random()
15
16 def choose(self) -> Bin:
17 return self.rng.choice(self.bins)
We’ve defined the second parameter, rng
, to be an instance
of random.Random
. The default value, however, is None
.
We’ll get the following kind of error:
code/wheel_examples.py:12: error: Incompatible default for argument "rng" (default has type "None", argument has type "Random")
This kind of thing requires us to be much more explicit in our statements of what the data type is.
We need to change the type hint of rng: random.Random=None
.
This needs to be rng: Optional[random.Random]=None
to more correctly state
what we expect for the parameter to this method.
Additionally, some assignment statements can be ambiguous. In this cases, we may need to add a type hint to an assignment statement.
some_dict: DefaultDict[str, int] = collections.defaultdict(int)
The collections.defaultdict()
function only includes a function to create a value to be created when a key
is not found. It doesn’t describe the type of the value or the type of the keys. The mypy tool can
examine the int()
function to determine the type of value returned. There’s no suggestion
about what the keys are, and Python doesn’t really need any suggestion.
In order to be confident, we need to provide a hint, using the typing.DefaultDict
type definition.
This definition lets us provide a key type and a value type. With this additional information,
the mypy tool can confirm that the some_dict
variable is used properly.
Static Code Quality Checks¶
The pylint tool does some checks for “style” issues. It can also check a number of programming techniques that – while legal – are likely to be a code smell. See https://www.pylint.org for the complete list of checks that can be performed.
We install this with conda, also.
conda install pylint
We run this to get a list of possible problems with the source code of the module.

-----------------------------------
Your code has been rated at 8.38/10
This outout lists a number of problems that are either omissions of docstrings or variables
with names that don’t follow the typical Python style, called “snake_case”. The names hardValue
and softValue
should be hard_value
and soft_value
.
This a pervasive change to the code examples throughout this book. We haven’t made the change, but the reader can consider revising their own code to reduce the number of pylint problems.
The rating, 8.38/10
, clearly shows room for improvement. Adding the required docstrings, for example,
would lead to a dramatic improvement in the quality metric.
Code Formatting¶
One way to achieve consistent and easy-to-read code is to use a code formatting tool. One of the more popular tools is black. This tool is described as “uncompromising.” It has relatively few options and produces consistent, easy-to-read code.
conda install black
The tool will simply reformat any valid Python to fit the recommended style. The black tool can also be used to confirm that a module is already formatted correctly. This becomes a kind of testing tool to confirm the formatting before doing a Git checkin, or starting a long integration and deployment process.
We can use it to reformat an entire directory tree like this:
black src
That’s all there is to it. It provides a very small summary of what it did. This is delightfully simple and creates consistent-looking source files.
Test Coverage Analysis¶
Generally, we want test cases to confirm the application under test will work. It’s difficult writing a good application, and it’s difficult writing good test cases. One of the key questions is how much of the software is covered by test cases. Ideally, a vague “all of the software” has been tested. The difficult problem is defining what “all” means.
There are a number of ways to measure software and decide if “all” of it has been tested.
Tests execute code in all of the modules.
Tests execute code in all of the classes.
Tests execute code in all of the methods of all of the classes.
Test execute all of the statements.
Tests evaluate both true and false for each condition expressed in an
if
,elif
, orwhile
statement; the implicit condition of eachelse
, so each each exception in atry
statement; also a test for eachfor
statement. These are the places were there’s a choice among statements to be executed.Tests exercise each possible combination of the conditional processing choices (
if
,elif
,else
, etc.)
Clearly, some of these don’t test very much, and some are quite complex to design.
It’s very easy to measure whether or not a test touches all of the statements. We’ll focus on this.
The Test Coverage Tool¶
Since we’re using pytest
, we can install the pytest-cov
plug-in. This will, in turn, install the coverage
tool.
conda install pytest-cov
To use the coverage tool, we need to provide a top-level module (or package of modules) for which we’d like coverage metrics.
PYTHONPATH=src pytest --cov=src
Here’s what the output looks like:
================================= test session starts =================================
platform darwin -- Python 3.7.4, pytest-5.0.1, py-1.8.0, pluggy-0.13.0
rootdir: /Users/slott/Documents/Writing/Technical/building-skills-oo-design-book/demo
plugins: cov-2.7.1
collected 4 items
tests/test_hw_1.py .. [ 50%]
tests/test_hw_2.py .. [100%]
---------- coverage: platform darwin, python 3.7.4-final-0 -----------
Name Stmts Miss Cover
-------------------------------
src/hw.py 11 1 91%
============================== 4 passed in 0.06 seconds ===============================
The pytest tool tells us it’s running two tests, test_hw_1.py
and test_hw_2.py
.
The final coverage report says the 91% of the code has been exercised.
What’s missing?
We an add the --cov-report=term-missing
option to see which lines were not tested.
Here’s the revised command.
PYTHONPATH=src pytest --cov=src --cov-report=term-missing
Here’s the revised coverage report
---------- coverage: platform darwin, python 3.7.4-final-0 -----------
Name Stmts Miss Cover Missing
-----------------------------------------
src/hw.py 11 1 91% 25
Line 25 is not exercised by the test. What is this difficult-to-test line?
24 if __name__ == "__main__":
25 main()
Line 25 is very hard to test with conventional unit testing approaches. It’s not impossible, but it’s difficult and the extra effort doesn’t create a lot of value.
We can add a special # pragma: no cover
comment to tell the coverage
tool to apply this “fact” or “pragma” to the line in question. This improves
the coverage score and adds a comment informing everyone of what line was
skipped.
Test Automation¶
We have a large suite of testing tools to provide real confidence in the quality of the application programming. It can seem daunting to keep all of the tools straight. The tox tool, however, gives us a path forward. We can use tox to run our suite of static and dynamic tests.
We’ll use pip to install tox.
python -m pip install tox
This is required because tox is not in any of the common respositories searched by conda.
Once we have tox installed, we need to create a configuration file.
This can be called pyproject.toml
or tox.ini
. The content of the
file will look like the following example:
[tox]
skipsdist = True
requires =
tox==3.14.0
[testenv]
ignore_errors = True
deps =
mypy==0.720
pylint==2.4.2
black==19.3b0
pytest==5.0.1
pytest-cov==2.7.1
setenv =
PYTHONPATH=src
commands =
mypy src
pylint src
black src
pytest --doctest-modules src
pytest --cov=src
The first section, [tox]
is general information about tox. The skipsdist
avoids
building a source distribution kit. We’re not going to upload this code to
the Python Package Index (https://pypi.org) sometimes called the “Cheese Shop.” Since
we’re not building a source distribution, we don’t need some of the overheads associated
with that step.
The main section, [testenv]
is repeated for each distinct test environment.
In this case, we only need one test environment, so we don’t have a complex configuration.
We’ve provided four distinct configuration values:
The
ignore_errors
makes sure the testing continues even if an error in one step has been found. This lets us run the whole suite of tests, then fix all of the problems.The
deps
defines the dependencies required to run the tests. We’ve listed specific versions of each tool.THe
setenv
defines the environment variables to provide when running the tests. The default setup provides very few environment settings. Because our application is located in asrc
directory, we need this to be on thePYTHONPATH
environment variable.The
commands
is a sequence of commands to execute. There are strict limitations on these commands. This allows thetox
tool to run in a wide variety of environments and remain perfectly consistent.
To run tox, we use the command
tox
If we’re in the same working directy as the tox.ini
(or pyproject.toml
) file, then
tox will execute each of the commands, giving us a detailed view of how well our application
passes the suite of quality assurance tests.
The use of a tool like tox makes test execution simple and consistent. It gives us a lot of help in producing useful, trustworthy, reliable software.
Looking Forward¶
In the next chapter we’ll look at what’s required to create a final, command line interface (CLI) to run the simulation command with various options and arguments.


Infinity (1996) A film review by Steve Rhodes Copyright 1996 Steve Rhodes
RATING (0 TO ****): ** 1/2
So what is the cube root of 1729.03, and what algorithmic short cuts can you employee to arrive at the answer? Do you think you could get the answer quicker than a high speed abacus driver? These are some of the conundrums that form the side show of INFINITY.
In Matthew Broderick's directorial debut, he tells the romantic and true story of Nobel prize winning physicist Richard Feynman (Matthew Broderick) and his wife Arline (Patricia Arquette from BEYOND RANGOON). Science does enter the picture as a subplot, but most of the show is devoted to the nine year romance between him and his dying wife.
Broderick knows exactly what he wants to do as a director and does it. He lovingly crafts an extremely slow moving film. His acting in the title role is dispassionate and unhurried with his emotions carefully kept in check. He is in no hurry to do anything nor get excited about any event. Even his wife's inevitable death brings barely a rise out of him. I have an image of Broderick in the director's chair coaching his cast to slow down and take each scene with carefully measured paces.
The entire show moves with strange rhythm that you will either find so languid you fall asleep or will cast a spell over you and draw you into the quiet world of a scientist's love affair. For some inexplicable reason, I found myself in the latter category, but if you see the film and find it feels like infinity watching it, I will understand. And yet, I found the film soothing as a warm bath and tranquil as a gentle breeze.
Early in his life, Richie's father Mel (Peter Riegert from CROSSING DELANCEY) demonstrates the value of science to him through simple experiments. I liked the little scene where his father corrects him with, "Richie, how old are you?" To which he replies, "six." "Well then, act your age," admonishes his dad. As a Daddy, I have found that fatherly advice sometimes seems to make little sense even when I am the one giving it so this scene hit home.
Richie falls in love with Arline and eventually marries her, but before the wedding date is even set, she develops a problem with her lymph glands. I'll spare you the medical science behind what might or might not have been the problem. The bottom line is that the show is about their time together before her almost inevitable death.
Richie loves to talk Math and Physics to her. He explains, "Mathematics is a language for the dead. I talk to Copernicus everyday." He loves doing household experiments like seeing if he can detect the last book she touched just by the smell.
Arline is a spunky and imaginative patient who lives in a hospital nearby for all of their married life. She sends him pencils with "I love you Popsie" on them. He scratches the words off so that his fellow graduate students at Princeton will not ridicule him. Another time, she sneaks a portable stove into her hospital room so they can go cook steaks out on the hospital lawn.
Their life does not change, but their locale does when, during World War II, they go to Los Alamos so he be part of the Manhattan Project to develop the first atomic bomb. My favorite scenes there are of the key punches, card sorters, plug board calculators they used in lieu of real computers. Since I saw these at my first programming job at Texas Instruments in the mid-60s, they brought back fond memories.
A typical scene in the show has Richie and a sick Arline making small talk together while he stacks milk bottle lids up top of each other, house of cards style. Other than convey serenity, the scene has no real purpose. Again, somehow, I found these little vignettes charming.
When the atomic bomb is finally denoted in the desert near Los Alamos, one scientist announces, "I'm giving odds we blow up the state of New Mexico. Any takers?" But, another muses, "How could we collect?"
Many technical aspects of the film are worth mentioning. Mary Jane Fort's costumes capture the look of a nerd in the 40s without overkill. The cinematography by Toyomichi Kurita is warm and almost hazy, and is nicely complemented by Bruce Broughton's dreamy music.
Finally, I must admit a little regret that the movie wasn't a stinker. I could have done a great two line review, "INFINITY is." Terse and to the point. Oh well, I guess I'd rather enjoy a good movie that write a funny review. Then again, ...
INFINITY runs a finite 1:59. It is rated PG, and there is no sex, nudity, violence, or bad language. The only reason it got a PG rather than a G is that the topic of realistic love and death by long term illness is not a theme for young children. On the other hand, any kid old enough to want to see it should be able to. I give the show a thumbs up and award it ** 1/2.
**** = One of the top few films of this or any year. A must see film. *** = Excellent show. Look for it. ** = Average movie. Kind of enjoyable. * = Poor show.  Totally unbearable.

Observers: Creating your own
You can add any class as an observer by adding the full classname (namespace included) to the Observers property of your model. There's 2 ways of creating classes that can be used as observers:
Extend the Orm\Observer class
Create a new class that extends Orm\Observer and create methods for the events upon which you want your Observer to act. In the example below you want it to act upon after_insert . The method will be passed the Model instance it is acting upon.
class Observer_Something extends Orm\Observer
{
public function after_insert(Orm\Model $model)
{
\Log::info('Succesfully created new object of class '.get_class($model));
}
}
Extensions of the type Orm\Observer are singletons by default, as such you can't use a method instance() or property $_instance or it won't work anymore. Because of this methods may be both static or non-static.
Have an orm_notify() method
When you extend the Orm\Observer class it inherits an orm_notify() method that will check if there's a method that matches the event and call it when possible. But you can use any class as an observer as long as it has an orm_notify() method. That will be called on events and be passed the event name and a Model instance.
class Some_Other_Class
{
// it may have many methods and properties before or after the orm_notify method
public static function orm_notify(Orm\Model $model, $event)
{
\Log::info('I was notified of the event '.$event.' on a Model of class '.get_class($model));
}
}
Event names
- after_create, called by the __construct() method once the object was created
- after_load, called by the __construct() method once an object was loaded from the database
- before_save, called by the save() method before anything is done
- after_save, called by the save() method after it has completed
- before_insert, called when an object is first saved to the database
- after_insert, called after an object is first saved to the database
- before_update, called when an object is saved to the database (except for the first time)
- after_update, called after an object is saved to the database (except for the first time)
- before_delete, called when you delete an object from the database
- after_delete, called after you delete an object from the database
- after_clone, called after an object was successfully cloned
before_insert and before_update are triggered only if the object has been changed. If you need to trigger an event even if the object has not been changed (ex.: to handle $_FILES datas), you should use before_save .

--- title: Case Study - Elba Island, Italy heading: Case Study - Elba Island, Italy description: Improving Tourism Promotion Using Google Street View image: /assets/images/pages/case-studies/2018/it/elba-island-meta.jpg layout: case-study ---
Elba Smart Exploring was a project commissioned by Visit Elba to enable anyone with a smartphone to explore the island's outdoor trails.
The island, housing over 200 beaches and 350 km of trails, wanted to focus its marketing towards outdoor adventure based holidaymakers.
By mixing Street View 360 imagery with dedicated online websites and content, the aim was to give tourists booking their visits the tools to plan their excursions by choosing and building personalised itineraries, from the comfort of their sofa.
The Elba Smart Exploring website allows you to choose your hike and start your virtual expedition.
The project received significant press attention, consequently helping to drive a 10% increase in tourism during the second half of 2018, measured by ferry tickets to the island (the only way on and off).
The project was presented by Federico Debetto, Head of Photography, at the 2018 Google Street View Summit in Mountain View.
Elba Exploring Smart was the first systematic mapping of the island, commissioned by Visit Elba.
The project is in line with a strategy, Elba Active, that launched in 2016, which sees the island increasingly projected towards outdoor activities, healthy food and nature.

Robbie Williams hints that he's too 'expensive' to return to The X Factor
Robbie and wife Ayda were on the panel last year
by Nancy BrownFormer X Factor judge Robbie Williams has hinted at the real reason he and wife Ayda haven't returned to the show's panel.
Speaking at the launch of Hyde Park's Winter Wonderland earlier this week, Robbie seemed to claim the pair were too "expensive" for the show.
Robbie and Ayda were on the talent show's panel last year, alongside Simon Cowell and Louis Tomlinson.
However, now the star – who performed tracks from his upcoming Christmas album at Winter Wonderland – has revealed why.

Speaking to the Mirror, Robbie said: "Look, it's expensive. We're expensive. Something's gotta give there."
He added: "Maybe they did think about us, maybe they didn't."
He also said that he would be asking Simon Cowell why they didn't get the call to appear on this year's celebrity version of the show when they catch up soon.

"I don’t know what's on Simon's mind, but I'll be meeting up with him before Christmas and I'll try to get it out of him," Robbie said.
Robbie will be back on our screens soon, though.
The star – whose first Christmas album, The Christmas Present, is out this weekend – revealed he's making a festive TV show for ITV.
It's Not The Robbie Williams Christmas Show will air this December.

The Kingdom Soldier's Creed
I
am more than a conqueror in Christ Jesus, a member of a chosen generation. I
serve the people of a holy nation and I live out the Kingdom values. I will
always place the will of my Lord and Savior first. I will never accept
defeat, for by my God I can run through a troop and by my God I can leap
over a wall. I will never quit, though I stumble and fall seven times I will
rise up. I will fight for my brethren, for my sons and my daughters, my
wife, and my King.
I take up my helmet of salvation; I put on my breastplate of righteousness;
I gird myself with the belt of truth, and having my feet shod with the
gospel of peace; I take up my sword of the Spirit and my shield of faith. I
am strong in the grace that is in Christ Jesus.
I endure hardness as a good soldier. I do not entangle myself with the
affairs of this life that I may please Him Who has chosen me to be a
soldier. I have consecrated myself unto the Lord, therefore He will do
amazing things in and through me.
The Lord shall cause my enemies that rise up against me to be smitten before
my face: they shall come against me one way, and flee before me seven ways.
I bring every thought captive to the obedience of Christ and tear down
strongholds and principalities by the power of God that works mightily
within me.
I know my God; I am strong and I do great exploits. I am courageous; I do
not fear the terror of night, nor the arrow that flies by day. A thousand
may fall at my side, ten thousand at my right hand, but it will not come
near me because I have made the Most High my dwelling; He is my refuge.
I love the Lord and acknowledge His name; He is with me in trouble and I
know He will deliver me. I am a Soldier of the King.
