To register instances with a stack
The following examples show a variety of ways to register instances with a stack that were created outside of AWS Opsworks. You can run register from the instance to be registered, or from a separate workstation. For more information, see Registering Amazon EC2 and On-premises Instances in the AWS OpsWorks User Guide.
Note: For brevity, the examples omit the region argument. AWS OpsWorks CLI commands should set region to us-east-1 regardless of the stack's location.
To register an Amazon EC2 instance
To indicate that you are registering an EC2 instance, set the --infrastructure-class argument to ec2.
The following example registers an EC2 instance with the specified stack from a separate workstation. The instance is identified by its EC2 ID, i-12345678. The example uses the workstation's default SSH username and attempts to log in to the instance using authentication techniques that do not require a password, such as a default private SSH key. If that fails, register queries for the password.
aws opsworks register --infrastructure-class=ec2 --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb i-12345678
The following example registers an EC2 instance with the specifed stack from a separate workstation. It uses the --ssh-username and --ssh-private-key arguments to explicitly specify the SSH username and private key file that the command uses to log into the instance. ec2-user is the standard username for Amazon Linux instances. Use ubuntu for Ubuntu instances.
aws opsworks register --infrastructure-class=ec2 --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb --ssh-username ec2-user --ssh-private-key ssh_private_key i-12345678
The following example registers the EC2 instance that is running the register command. Log in to the instance with SSH and run register with the --local argument instead of an instance ID or hostname.
aws opsworks register --infrastructure-class ec2 --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb --local
To register an on-premises instance
To indicate that you are registering an on-premises instance, set the --infrastructure-class argument to on-premises.
The following example registers an existing on-premises instance with a specified stack from a separate workstation. The instance is identified by its IP address, <IP_ADDRESS>. The example uses the workstation's default SSH username and attempts to log in to the instance using authentication techniques that do not require a password, such as a default private SSH key. If that fails, register queries for the password.
aws opsworks register --infrastructure-class on-premises --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb <IP_ADDRESS>
The following example registers an on-premises instance with a specified stack from a separate workstation. The instance is identified by its hostname, host1. The --override-... arguments direct AWS OpsWorks to display webserver1 as the host name and <IP_ADDRESS> and <IP_ADDRESS> as the instance's public and private IP addresses, respectively.
aws opsworks register --infrastructure-class on-premises --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb --override-hostname webserver1 --override-public-ip <IP_ADDRESS> --override-private-ip <IP_ADDRESS> host1
The following example registers an on-premises instance with a specified stack from a separate workstation. The instance is identified by its IP address. register logs into the instance using the specified SSH username and private key file.
aws opsworks register --infrastructure-class on-premises --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb --ssh-username admin --ssh-private-key ssh_private_key <IP_ADDRESS>
The following example registers an existing on-premises instance with a specified stack from a separate workstation. The command logs into the instance using a custom SSH command string that specifies the SSH password and the instance's IP address.
aws opsworks register --infrastructure-class on-premises --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb --override-ssh "sshpass -p 'mypassword' ssh<EMAIL_ADDRESS>The following example registers the on-premises instance that is running the register command. Log in to the instance with SSH and run register with the --local argument instead of an instance ID or hostname.
aws opsworks register --infrastructure-class on-premises --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb --local
Output: The following is typical output for registering an EC2 instance.
Warning: Permanently added '<IP_ADDRESS>' (ECDSA) to the list of known hosts.

DEEP IMPACT (1998) A "Turkey of the Week" film review by Justin Felix. Copyright 1998 Justin Felix.
Rating: *** (out of five)
Written by Michael Tolkin and Bruce Joel Rubin. Directed by Mimi Leder. Starring Robert Duvall, Tea Leoni, Elijah Wood, Vanessa Redgrave, Maximilian Schell, Morgan Freeman. Rated PG-13 (contains violence and profanity) approx. 110 mins.
 A crew of astronauts attempt to blow up the comet with nuclear devices but only manage to split the comet in two. A salvo of nuclear weapons, a massive underground shelter, and the astronauts' desperate second plan become man's only hope for survival.
Comments: Judging from DEEP IMPACT's previews, I expected the worse. With syrupy phrases bandied about like "oceans rise," "cities fall," and "hope survives," along with a melodramatic score in the background and a rather cheesy image of a tidal wave knocking buildings over in New York City, the movie did not seem promising. Add to this the fact that another high-profile summer flick, ARMAGEDDON, deals with basically the same topic -- Hollywood has a hard time coming up with respectable disaster movies in pairs (as the recent volcano and earthquake debacles illustrate). I was, however, somewhat surprised by DEEP IMPACT's strengths. Instead of a turkey, it's a better-than-average TV mini-series with a bloated 75 million dollar budget and a shorter running time.
Those 75 million bucks seemed well-spent, surprisingly. The special effects in DEEP IMPACT are very noteworthy (quite a feat considering the countless movies Hollywood releases now which are predominantly effects-driven). Nothing shown in this movie, to further the surprise, is particularly new or innovative. People flee in vain through a crowded New York City street, for example, with a giant tidal wave smashing buildings and consuming cars behind them, a scene almost stolen from INDEPENDENCE DAY (same city, similar street -- only, in ID4, it was fire rather than water). Similar destruction, both in cities and in the countryside, have been seen in many other recent natural disaster flicks. VOLCANO, DAYLIGHT, and DANTE'S PEAK come to mind. This doesn't, however, lessen the impact that such images of destruction has on the audience (no pun intended). Though highly unrealistic, the outer space sequences are also visually stunning, perhaps the best in the film.
Whatever was left over in the budget after the special effects was still well-spent. DEEP IMPACT sports a very solid, respectable cast. Robert Duvall and Morgan Freeman give the most notable performances. Duvall, fresh off of his Academy Award-nominated work on THE APOSTLE, pulls at the heartstrings as an aging astronaut named Spurgeon Tanner. Tanner, an experienced navigator and recent widower, overcomes the age discrimination of his much younger crew to become a leader and a hero convincingly. Morgan Freeman's always powerful presence lends credence to his job playing the President of the U.S. Screen vets Maximilian Schell and Vanessa Redgrave play the divorced parents of the reporter who breaks the story very well. The reporter, Jenny Lerner, played by Tea Leoni, is the only casting misfire here. Leoni is wooden and unconvincing throughout; she lacks charm, and many of her scenes are hollow and unsatisfying. As one of the major characters in the movie, this is a striking fault.
Another fault, admirable as it may be, is that DEEP IMPACT attempts too much. I made a comparison earlier between this film and a TV mini-series. DEEP IMPACT needs four or six hours to satisfactorily tell its tale. The story takes place over the course of a couple of years and involves a great many characters. We see the President and the government, the news media, the astronauts of the space shuttle "Messiah," and numerous everyday, middle-class, mostly white Americans. Many of these characters are complex and fascinating, yet not enough time is spent on them. In order to be more in-depth in a 2 hour movie, perhaps the screenwriters could have concentrated upon one group of characters. My vote would have gone to the "Messiah." The astronauts are uniformly interesting; all have families on Earth (so we still would have a tie to the Earth); and, their sacrifices are some of the most memorable in the movie. We don't see them in training; they're just introduced suddenly, given a party, and launched into space.
Focusing upon the astronauts would have also saved the audience from sentimentally absurd scenes involving the middle-class, suburban, American characters. As primarily a disaster film (one could legitimately argue this is science fiction as well), DEEP IMPACT follows some of the cliches which appear in other movies of this genre. We have pregnant women, parents who sacrifice themselves for their children, and despicable characters who turn over new leaves in order to become heroes. Thankfully, a dog doesn't play a prominent role here (dogs-in-jeopardy, a tired element seen in disaster epics like DAYLIGHT, etc.). Young love, however, does appear: the child who unknowingly discovers the comet falls in love, gets married to save his sweetheart (he's picked to go into the underground shelter; she is not), follows her as she decides to spend the apocalypse with her parents, and then finds her, somehow, just in time to witness the movie's climactic ending. Please. This was the most unlikely subplot of the film, and I, for one, did not buy it. Though, as my friend and I vacated the theater, I overheard two teenage girls talk about how they hadn't cried so much at a film in a long time. I guess it worked for some people.
Removing the plot from the critical equation (let's face it, most special-effects driven films ask you to swallow a lot that's unbelievable), DEEP IMPACT is an entertaining, diverting, early film for the Summer of 1998. This is a film to check out on the big screen. Rated PG-13, this film makes a pretty good matinee movie with little that would offend the audience. The rather convoluted storyline, though, may tax some children's understanding and patience.

In this studio you will simulate the throw of a number of Dice. This will require using what you have learned in Module 2 and Module 1 but will also require the use of arrays as taught in this module.
We ask that you follow these instructions carefully, step-by-step, so as to develop your code by concept refinement. Each concept is first described, and then your group takes steps to implement the concept.Ask questions as needed to complete one step before going on to the next.
As an example, if D is 3, then a given throw could be:
As an example, if T is 5, then the dice could be thrown as follows:
| Figure 1 | ||
|---|---|---|
At this point,
- Create a class Dice in the studio3 package (which is in the studios source folder).
- Decide on meaningful variable names for the concepts introduced so far:
- The number of dice used in this simulation.
- The number of times the dice are thrown.
- Insert code to obtain the values for these variables from the user.
If you have forgotten how to do this, look at examples from previous studios or look at the code from lecture.- Test your code at this point, printing out the values you have received.
For the purposes of this lab, let's say that each die is six-sided, and therefore labeled to show the values 1…6. If you have time, you might consider how to change your code to accommodate dice that have fewer or more than 6 sides.You need to iterate, assigning each die's roll the value that it shows in your simulated roll. Pseudocode for this activity is shown below:
// Pseudocode // for each die d // randomly throw d to obtain the value v, shown face-up on d // end
Spoilers: You will need to sum the values shown on the dice. You should therefore pick a representation that makes this easy.
Consider the example shown in Figure 1. After the first throw, we have:
int[] diceThrown = new int[D] // for each die d // randomly throw d to obtain the value v, shown face-up on d // record die d's role in the diceThrown array // end // At this point, your dieThrown array has an entry that shows each die's value
Review the material we have been studying on arrays, and discuss as a group how to deply the above array to remember each die's value after it has been thrown. Instantiate the array in your code and make sure its size is exactly right for the task at hand.For the example above, your array might look like:
| array index | 0 | 1 | 2 |
|---|---|---|---|
| array contents | 3 | 5 | 3 |
| represents |
Recall T was a value prompted from the user. It is the number of times we will throw the dice.You do not need a different or larger array than the one you already have. You only need to remember the dice values after each throw. You will not be required to remember the values from all of the throws.
What are the steps needed to make a concept real? Some related questions are:
- How can we determine if all dice have the same value after they are thrown? Fortunately, you have stored the dice values so they can be examined after they have all been thrown.
- How do we keep track of the number of times they all have the same value?
- How do we report the fraction of times they all have the same value?
Take those steps now so that your code can determine when all of the dice values are the same. Arrange for your program to print out the fraction or percentage of times the throws result in the same value for all dice.
Make this concept real taking the usual steps.
Make sure the results seem reasonable.
If you get this far, that is great, and we will demo you and consider your work done. If you have time now, or inclination later, take a look at the rest and see if you can do it.This will help prepare you for the exam.
| Sum | Number of times Sum was seen |
|---|---|
| 7 | 1 |
| 8 | 2 |
| 11 | 1 |
| 18 | 1 |
To make this concept real, have the following discussion:
- What values could the sum possibly take, given that there are D dice?
- Based on what we have studied thus far, kind and type of variable is needed to keep track of the sums?
- Where in your code should you update how often a sum occurs?
For D dice, which sums occur most frequently? You can determine this by running your program on different numbers of dice, but using enough iterations to show typical behavior.

BeeSafe Project

Low-cost tracking device.

This page discusses the electronic components and considerations made for designing the schematic and layout.

.Note: This picture is the untested hardware V1.1 and still has an error in the voltage translator configuration.
The mobile connectivity is provided by the SARA-G350-02X-01 module (hereafter: SARA module).
The original idea of the project was to have a GSM and a GPRS module. However, each of these costs about 20£ when bought in low quantities and 40£ is the budget for this project, there would be nothing left for the rest of the necessary components. A module that provides both functionalities in one is often more expensive than those 40£ because it is highly integrated and optimised for space. Additionally, these tiny modules would be impossible to solder without a solder stop mask.
This is where the SARA module comes into play. It provides the so-called CellLocate
feature. A way to determine the location of the module based on mobile network information. In certain cases, it can provide location information when there is no GPS signal available (for example indoors), or it can improve the estimated GPS location. When used on its own, CellLocate might not be as accurate as GPS. The SARA module provides the possibility to connect a GPS module if this prototype proves to be not accurate enough.
The communication to the Raspberry PI is done through a UART interface. The SARA module provides two UART interfaces, one 9-pin providing full hardware flow control and one auxiliary UART interface using only RX and TX signals. Additionally, two GPIOs are connected to the PI that alow the SARA module to send interrupts to the PI (can be configured in software).
The signal names of the SARA modules’ UART interface conform to the ITU-T V.24 Recommendation: e.g. the TXD line represents the data transmitted by the DTE (Raspberry PI) and received by the DCE (SARA module). Therefore, the RX/TX line from the PI and the SARA module can be connected TX-TX and RX-RX. However, the two devices operate on different voltage levels, so a voltage translator is needed.
The SIM Card is directly connected to the SARA module, the SARA module provides the power supply for the SIM card.
The SARA module has both a PWR_ON and a RESET_N pin. For normal operation, they both have to be at a high level. The PWR_ON pin must be connected to 3V8 with a 100 kΩ resistor. The RESET_N pin has an internal pull-up, it is not connected. A reset can also be forced through an AT command, the RESET_N pin is only needed if this fails.
The PWR_ON pin is connected to GND by a resistor that is not connected (NC). This was done to have the possibility to implement this function during development. Similarly, the RESET_N pin connects to a 0 Ω resistor, to give access to the pad during development, should it be needed.
Most pins connected to the SARA module and some additional ones are separated from the rest of the circuit through 0 Ω resistors. This was done to be flexible during development. The main UART could be swapped with the auxiliary one, RX/TX could be changed if necessary, or additional features (GPIO or reset) could be connected to the PI.
During development, we were able to change the direction of the voltage translator, because that was configured incorrectly. The result does not look very pretty, but it works. No new PCB had to be manufactured.
The PI supplies 5 V directly from the USB connection and 3.3V for its digital in- and outputs. The SARA module, however, needs a supply voltage of 3.8 V typically (3.35 - 4.5 V max). The module peak of current consumption through all the VCC pins, during data transmission, burst at maximum power level, with a mismatched antenna is 1.9 A (1.5 A with a matched antenna).
The SIM Card runs on 1.8 V. Because the SARA module communicates directly with the SIM card, its digital interfaces also run on 1.8 V and the SIM can be supplied by the SARA module directly.
The 3.8 V is generated from the 5 V supply using a Low Dropout Regulator (LDO) from Linear Technology (LT1764 series, adjustable device, see BOM
) with the recommended schematic design (find full schematic in hardware
). It can provide a current of up to 3 A.
For the communication between the PI (3.3 V) and the SARA module (1.8 V) to work, a 4-bit noninverting bus transceiver with two separate configurable power-supply rails from Texas Instruments was used (see BOM
). It translates UART TX from the PI to the module and UART RX and two GPIOs from the module to the PI.
It is permanently activated by pulling the ~OE pin to GND (pulling it to supply voltage would put all ports into high impedance state). The direction is set by pulling the direction pin to GND for transmission from port A (Raspberry PI) to port B (SARA module) or to supply voltage for transmission from port B (SARA module) to port A (Raspberry PI).
To be on the save side, an external antenna connected to the standard SMA connector is used. The used antenna is the W3404SMA from Pulse Larsen Antennas and has a frequency range of 698MHz ~ 960MHz and 1.71GHz ~ 2.69GHz.
The most important requirements are:
Using an external antenna gets rid of most layout problems that would be caused by an onboard antenna. The connection from the antenna pin of the SARA module to the SMA connector is kept as short as possible. This should not cause any problems as long as the connection is shorter than 1/4 of the wavelength (418 mm for 1.8 GHz).
The SIM card adapter accepts micro-SIM cards with a push-pull mechanic. The footprint seems to be very similar/the same to many micro-SIM adapters. The exact component can be found in the BOM
.
To protect the circuit from RF coupling (especially from the antenna), several bypass capacitors were placed close to the pads of the SIM connector as well as ESD protection diodes as recommended by the hardware integration manual of the SARA module. The newest version of the schematic can be found in the root of the hardware
folder.
Optional SIM detection from the SARA module is not supported by this hardware version.
The expansion board has the same size as the Raspberry PI. Because the USB ports on the PI are too high for a standard header, an extra tall one is needed. This is one example, specifically made for this purpose by Adafruit
.

(SV16) The mixing time of the Dikin walk in a polytope - a simple proof

Problem: sample a point from the uniform distribution in a polytope \(K\subeq \R^n\). (This is used in many algorithms.)
Main theorem (informal): From a warm start (i.e., density \(\Pj(A)\le C\Pj_{U_K}(A)\) where \(U_K\) is the uniform distribution on \(K\)), the Dikin walk mixes in time \(O(mn)\) for a \(n\)-dimensional polytope described with \(m\) inequalities.
Consider the random variable \(g_x\) given by \[ z = x + \fc{r}{\sqrt n} H(x)^{-\rc 2}g,\quad g\sim N(0,1),\] i.e. it is a Gaussian with covariance matrix \(\fc{r^2}{n}H(x)^{-1}\) centered at \(x\).
Let \(p_x\) be the \(g_x\) with the Metropolis filter applied, \[ p_x(z) = \min\{g_x(z),g_z(x)\}\] (stay at \(x\) with remaining probability).
Define the cross-ratio distance \[\si(x,y) = \fc{|\ol{xy}||\ol{pq}|}{|\ol{px}||\ol{qy}|},\] where \(xy\) hits the boundary of \(K\) at \(p,q\) (\(pxyq\) are in that order). \(\ln (1+\si(x,y))\) is a metric on \(K\).
Theorem 1: Given a reversible random walk in \(K\) with stationary distribution uniform, suppose \(\exists \De>0\) such that for all \(x,y\in K\) with \(\si(x,y)\le \De\), \(\ve{p_x-p_y}_1\le 1-\Om(1)\). Then after \(O(\De^{-2})\), the lazy version of the walk from a warm start is within \(\rc4\) TV distance from the uniform distribution.
(This is saying something about uniform continuity of \(x\mapsto p_x\). There’s a “smoothing out” effect.)
Proof of main theorem.


ONE: ‘Age of Dragons’ preview (Pt. 2)
by James GoyderONE: “Age of Dragons” is set for Beijing this Saturday and matchmakers have obviously decided that stand-up fights will appeal to the Chinese audience. The card is headlined by two kickboxing title bouts.
In the main event, Ilias Ennahachi defends his flyweight kickboxing title for the first time against Wang Wenfeng, who will be looking to become the first Chinese man to ever win a title with the promotion.
The co-headliner pits Tarik Khbabez against Roman Kryklia in another kickboxing title bout. The inaugural light heavyweight belt will be on the line and matchmakers will be hoping these two heavy hitters can produce fireworks.
Here’s my preview of the last five fights:
Miao Li Tao vs. Jeremy Miado ( Strawweight )
Miao Li Tao (5-1) has won three ONE Championship bouts in a row. He is a wrestler but has some serious punching power as Dejdamrong Sor Amnuaysirichoke discovered to his cost.
Jeremy Miado (8-4) also holds a one punch KO win over Dejdamrong although he was stopped in the rematch. The Filipino has lost four of his six ONE Championship fights.
Kickboxing: Yodsaenklai Fairtex vs. Jamal Yusupov (Catchweight)
Yodsaenklai Fairtex remains one of the biggest names on the ONE Super Series roster despite his disappointing defeat at the hands of Samy Sana. The big hitting southpaw is based in China and will be looking to bounce back with a big performance here.
Jamal Yusupov appears to have accepted this fight at very late notice. There’s not much information available about the Russian, so it would be a major surprise if he cause Yodsaenklai significant problems.
Meng Bo vs. Laura Balin ( Atomweight )
Meng Bo (13-5) has been scheduled to make her ONE Championship debut against Mei Yamaguchi on two separate occasions this year. Both bouts fell through but the Chinese atomweight’s main claim to fame is a 2013 win over UFC champ Weili Zhang.
Laura Balin (11-5) will be looking to secure her first ONE Championship win at the fourth attempt. She did go the distance with reigning strawweight champion Xiong Jingnan in a five round title fight in 2018.
Tarik Khbabez vs. Roman Kryklia (For Inaugural Light Heavyweight Title)
Tarik Khbabez has blown his way through the competition in ONE Championship’s light heavyweight division. The hard hitting Dutchman has scored four wins out of four and was rewarded with a title shot.
Roman Kryklia has already dropped a decision to Khbabez one. But the tall Russian is riding an eight fight winning streak and will look to use his height and reach to good effect here.
Kickboxing: Ilias Ennahachi (c) vs. Wang Wenfeng (For Flyweight Title)
Ilias Ennahachi and Wang Wenfeng have fought twice, sharing a decision win apiece. However the Chinese fighter’s win was clearly the more dubious of the two.
Ennahachi hits hard and knows how to use his hands in a kickboxing bout, as Petchdam Petchyindeeacademy discovered to his cost. The Dutch fighter will be looking to score another impressive win here.
The entire ONE: “Age of Dragons” fight card will be available to view live and free in some territories using the newly launched app which you can download here.

Modules/Apps¶
Modules allow you to get Django’s plug and play behaviour. The are functionally similar to Django apps. Modules are created in the modules folder. This makes it easier to comprehend than Django as you can see at a glance what is the main script and what are modules/apps.
Easy way to create module¶
Once in a Shopyo project, run
shopyo startapp modulename
or you can do
python manage.py startapp modulename
What make up modules¶
Modules have the following structure, where product is the module name. The EuroPython talk under the Education Section might be insightful
product/
tests/
static/
templates/
product/
templatefile.html
forms.py
info.json
models.py
view.py
global.py # optional
upload.py # optional
The command in the last section auto creates it for you!
info.json¶
The info file allows you to specify module config. This allows you to specify the module url and panel icon.
{
"display_string": "Page",
"module_name":"page",
"type": "show",
"fa-icon": "fa fa-store",
"url_prefix": "/page",
"dashboard": "/dashboard"
}
display_string
: Display name on control panel. If you decide to use Shopyo as a Flask base, it does not matter thenmodule_name
: Shopyo uses this to reference the module. Not to be duplicatedtype
: Used to show or hide modules on control panel. If control panel module not present, you can skip itfa-icon
: Used to show fontawesome icon on control panel. If control panel module not present, you can skip iturl_prefix
: Needed to specify module’s base urldashboard
: Used to redirect in control panel. For example the contact module’s url is /contact. But we want it to be public. So we have a panel redirect of /dashboard to direct admin to /contact/dashboard. Dont include if you don’t want redirect
Default Modules¶
Admin
Appointment
Base
Category
Contact
Control Panel
Internals
Login
Page
People
Setting
Using Shopyo as a Flask base¶
You can customise Shopyo in many ways
In case you want a partial customisation, keep the following modules:
Control Panel
Admin
Base
Login
Settings
In case you want even more customisation, keep the base module and modify it
If you want even more customisation, just delete all modules from modules/ folder then run shopyo startapp your_module
. In which case, remove models import from shopyoapi/uploads.py
Importing modules¶
If you want to import from forms.py in same folder you write from .forms import ...
. If you want to import from other modules you do: `from modules.modulename.forms import ...`
global.py¶
Expects
available_everywhere = {
}
Where you pass functions or vars or classes you want to makle available in all templates! Try ‘x’: 1
upload.py¶
upload.py has a def upload(): function where uploads should be done. put upload codes in the function using app.app_context()
Here is a demo:
Boxes or many apps together¶
If you want to create submodules, first create a box:
python manage.py startbox demo
This will be created as box__demo in modules/
Then create the submodule:
python manage.py startsubapp demoapp in box__demo
If you go to url /demoapp, you will get Demoapp returned

A loop is a construct that allows us to perform one or more actions again and again. In awk, a loop can be specified using a while, do, or for statement.
The syntax of a while loop is:
while (
condition
)
action
The newline is optional after the right parenthesis. The conditional expression is evaluated at the top of the loop and, if true, the action is performed. If the expression is never true, the action is not performed. Typically, the conditional expression evaluates to true and the action changes a value such that the conditional expression eventually returns false and the loop is exited. For instance, if you wanted to perform an action four times, you could write the following loop:
i = 1 while ( i <= 4 ) { print $i ++i }
As in an if statement, an action consisting of more than one statement must be enclosed in braces. Note the role of each statement. The first statement assigns an initial value to i. The expression "i <= 4" compares i to 4 to determine if the action should be executed. The action consists of two statements, one that simply prints the value of a field referenced as "$i" and another that increments i. i is a counter variable and is used to keep track of how many times we go through the loop. If we did not increment the counter variable or if the comparison would never evaluate to false (e.g., i > 0), then the action would be repeated without end.
The do loop is a variation of the while loop. The syntax of a do loop is:
do
action
while (condition
)
The newline is optional after do. It is also optional
after action
providing the statement is terminated
by a semicolon. The main feature of this loop is that the conditional
expression appears after the action. Thus, the action is
performed at least once. Look at the following do loop.
BEGIN { do { ++x print x } while ( x <= 4 ) }
In this example, the value of x is set in the body of the loop using the auto-increment operator. The body of the loop is executed once and the expression is evaluated. In the previous example of a while loop, the initial value of i was set before the loop. The expression was evaluated first, then the body of the loop was executed once. Note the value of x when we run this example:
$awk -f do.awk
1 2 3 4 5
Before the conditional expression is first evaluated, x is incremented to 1. (This relies on the fact that all awk variables are initialized to zero.) The body of the loop is executed five times, not four; when x equals 4, the conditional expression is true and the body of the loop is executed again, incrementing x to 5 and printing its value. Only then is the conditional expression evaluated to false and the loop exited. By changing the operator from "<=" to "<", or less than, the body of the loop will be executed four times.
To keep in mind the difference between the do loop and the while loop, remember that the do loop always executes the body of the loop at least once. At the bottom of the procedure, you decide if you need to execute it again.
For an example, let's look at a program that loops through the fields of a record, referencing as many fields as necessary until their cumulative value exceeds 100. The reason we use a do loop is that we will reference at least one of the fields. We add the value of the field to the total, and if the total exceeds 100 we don't reference any other fields. We reference the second field only if the first field is less than 100. Its value is added to the total and if the total exceeds 100 then we exit the loop. If it is still less than 100, we execute the loop once again.
{ total = i = 0 do { ++i total += $i } while ( total <= 100 ) print i, ":", total }
The first line of the script initializes the values of two variables: total and i. The loop increments the value of i and uses the field operator to reference a particular field. Each time through the loop, it refers to a different field. When the loop is executed for the first time, the field reference gets the value of field one and assigns it to the variable total. The conditional expression at the end of the loop evaluates whether total exceeds 100. If it does, the loop is exited. Then the value of i, the number of fields that we've referred to, and the total are printed. (This script assumes that each record totals at least 100; otherwise, we'd have to check that i does not exceed the number of fields for the record. We construct such a test in the example presented in next section to show the for loop.)
Here's a test file containing a series of numbers:
$cat test.do
45 25 60 20 10 105 50 40 33 5 9 67 108 3 5 4
Running the script on the test file produces the following:
$awk -f do.awk test.do
3 : 130 2 : 115 4 : 114 1 : 108
For each record, only as many fields are referenced as needed for the total to exceed 100.
The for statement offers a more compact syntax that achieves the same result as a while loop. Although it looks more difficult, this syntax is much easier to use and makes sure that you provide all the required elements of a loop. The syntax of a for loop is:
for (
set_counter
;test_counter
;increment_counter
)
action
The newline after the right parenthesis is optional. The for loop consists of three expressions:
States a condition that is tested at the top of the loop.
Increments the counter each time at the bottom of the loop, right before testing the test_counter again.
Look at this rather common for loop that prints each field on the input line.
for ( i = 1; i <= NF; i++ ) print $i
As in the previous example, i is a variable that is used to reference a field using the field operator. The system variable NF contains the number of fields for the current input record, and we test it to determine if i has reached the last field on the line. The value of NF is the maximum number of times to go through the loop. Inside the loop, the print statement is executed, printing each field on its own line. A script using this construct can print each word on a line by itself, which can then be run through sort | uniq -c to get word distribution statistics for a file.
You can also write a loop to print from the last field to the first.
for ( i = NF; i >= 1; i-- ) print $i
Each time through the loop the counter is decremented. You could use this to reverse the order of fields.
The grades.awk script that we showed earlier determined the average of five grades. We can make the script much more useful by averaging any number of grades. That is, if you were to run this script throughout the school year, the number of grades to average would increase. Rather than revising the script to accommodate the specific number of fields, we can write a generalized script that loops to read however many fields there are. Our earlier version of the program calculated the average of 5 grades using these two statements:
total = $2 + $3 + $4 + $5 + $6 avg = total / 5
We can revise that using a for loop to sum each field in the record.
total = 0 for (i = 2; i <= NF; ++i) total += $i avg = total / (NF - 1)
We initialize the variable total each time because we don't want its value to accumulate from one record to the next. At the beginning of the for loop, the counter i is initialized to 2 because the first numeric field is field 2. Each time through the loop the value of the current field is added to total. When the last field has been referenced (i is greater than NF), we break out of the loop and calculate the average. For instance, if the record consists of 4 fields, the first time through the loop, we assign the value of $2 to total. At the bottom of the loop, i is incremented by 1, then compared to NF, which is 4. The expression evaluates to true and total is incremented by the value of $3.
Notice how we divide the total by the number of fields minus 1 to remove the student name from the count. The parentheses are required around "NF - 1" because the precedence of operators would otherwise divide total by NF and then subtract 1, instead of subtracting 1 from NF first.
The factorial of a number is the product of successively multiplying that number by one less than that number. The factorial of 4 is 4 × 3 × 2 × 1, or 24. The factorial of 5 is 5 times the factorial of 4 or 5 × 24, or 120. Deriving a factorial for a given number can be expressed using a loop as follows:
fact = number for (x = number - 1 ; x > 1; x--) fact *= x
where number is the number for which we will derive the factorial fact. Let's say that number equals 5. The first time through the loop x is equal to 4. The action evaluates "5 * 4" and assigns the value to fact. The next time through the loop, x is 3 and 20 is multiplied by it. We go through the loop until x equals 1.
Here is the above fragment incorporated into a standalone script that prompts the user for a number and then prints the factorial of that number.
awk '# factorial: return factorial of user-supplied number BEGIN { # prompt user; use printf, not print, to avoid the newline printf("Enter number: ") } # check that user enters a number $1 ~ /^[0-9]+$/ { # assign value of $1 to number & fact number = $1 if (number == 0) fact = 1 else fact = number # loop to multiply fact*x until x = 1 for (x = number - 1; x > 1; x--) fact *= x printf("The factorial of %d is %g\n", number, fact) # exit -- saves user from typing CRTL-D. exit } # if not a number, prompt again. { printf("\nInvalid entry. Enter a number: ") }' -
This is an interesting example of a main input loop that prompts for input and reads the reply from standard input. The BEGIN rule is used to prompt the user to enter a number. Because we have specified that input is to come not from a file but from standard input, the program will halt after putting out the prompt and then wait for the user to type a number. The first rule checks that a number has been entered. If not, the second rule will be applied, prompting the user again to re-enter a number. We set up an input loop that will continue to read from standard input until a valid entry is found. See the lookup program in the next section for another example of constructing an input loop.
Here's an example of how the factorial program works:
$factorial
Enter number:5
The factorial of 5 is 120
Note that the result uses "%g" as the conversion specification format in the printf statement. This permits floating point notation to be used to express very large numbers. Look at the following example:
$factorial
Enter number:33
The factorial of 33 is 8.68332e+36

I have been fortunate enough to perform a number of roles that have been directly impactful on both individuals and society as a whole.
In general, I try to seek out meaningful work. My approach has been to mix it up as sadly more meaningful work is not always available or viable.
I am often asked for advice on career direction and how to balance the pursuit of meaningful work with other career needs, such as skills, industry experience and improving networks.
I think that meaningful work is an ambition we all have, albeit are abilities to realise this for ourselves could be constrained by a whole number of factors that may or may not be within our control. I think this common ambition rises above stereotype threats (arising from being a minority in the workplace).

Review: AMERICAN HISTORY X
Starring: Edward Norton, Edward Furlong, Avery Brooks, Beverly D'Angelo, Stacy Keach, Elliott Gould, Jennifer Lien, Ethan Suplee
Directed by: Tony Kaye
Review by: Joy Wyse
American History X is not an easy film to watch. Looking back on it I remember the song from `South Pacific' whose lyrics are: `You've got to be taught to be afraid, of people whose eyes are oddly made, of people whose skin is a different shade. You've got to be carefully taught.' That is the basic story behind American History X. What makes a young man, Derek Vinyard [Edward Norton] become a skinhead? How did he learn to hate? In part, he learns from Cameron Alexander [Stacy Keach] who enlists Derek to entice other disgruntled white teens to join his army of hatemongers.
But there's more to the story than that. Although the action supposedly takes place in one twenty-four hour period, the flashbacks take it back through previous years. Danny Vinyard [Edward Furlong] has been called into the office of Mr. Sweeney [Avery Brooks] for writing an essay about the civil rights of Adolf Hitler. It is feared that Danny, in emulating his older brother, Derek, is headed down the same path. Derek is being released from prison that day. He has served a three-year sentence for manslaughter for killing two black teens. The killing scenes are especially graphic. Mr. Sweeney gives Danny the homework assignment of writing about Derek and the course of his life to replace the unacceptable essay.
Derek is not a totally unlikable person.  When he is released from prison, he has changed. His friends, such as Seth [Ethan Suplee] cannot understand this change. During Derek's imprisonment Seth and most of his other friends have banned together under the leadership of Cameron Alexander. They are not a likeable group. It's sad to realize that there are groups like this all over America today.
There are too many subplots to mention and not all of them are satisfactory. We are dealing with a dysfunctional family who is really very close. They don't seem to realize just how dysfunctional they really are.
I really enjoyed this movie, but I doubt that it will make any impact on the movie audiences. In many ways I fear that it could incite haters to hate even more. I'm glad that I saw it, but it is disturbing. I don't want to believe that this can happen. I definitely don't want to see it again, not even on free TV. The best thing about it is the acting. Everyone in it is totally believable, and the two Edwards are destined to be respected actors, which is more important than being `stars'. I give it a C.

| Introduction |
| Dependencies |
| Building The Source Code |
| Running The Tests |
| Source Code Structure |
Before attempting to build the source code make sure that you have read the section about the project dependencies. The building process has only been tested on a Redhat Linux distribution but there is no reason why it shouldn't work on other Linux versions. To make the proces of compiling the source code easier a make file is provided in the build directory. In order to use this make file it requires the pkg-config tool to be installed and configured correctly so that the header and library files for the the packages described in the dependencies section can be found. If the tool doesn't work then you will need to replace the pkg-config calls in the CFLAGS and LIBS lines of the make file with the location of the library and header files for D-Bus and GLib. Before the first time that you compile the source code you will need to run
make dirs
to ensure that all the required directories are created and then after that just call "make" to build the source. This will result in an executable called Platform that can be run, see section Running The Tests to find out how to use this program
There is a seperate make file provided for the SWIG implementation that should be used if you wish to make use of the API from a language other than C. The make file builds a shared library and uses the inteface file to build only Java bindings but other options could easily be added yourself. In order to compile this section of the solution go to the SWIG directory and just type "make" at a terminal, the platform code must have been built prior to compiling the SWIG stuff. This make file has the same reliance on the pkg-config tool as the make file described above, so similar measures will have to be taken if pkg-config does not work on your system.
| First Param | Second Param | Test Description |
|---|---|---|
| amsmod | Demonstrates that an agent is able to modify its entry in the AMS directory. It deliberately bypasses the normal de-registration procedure | |
| amssearch | Searches the AMS for an agent called "server" which should be started up prior to running this by running the server test giving the name as server | |
| agent | {agent-name} | The agent that forms part of the small test agent system that sends a FIPA-ACL message to agents called server1 and server2 and waits for a response before exiting. Prioir to running these tests at least the two server agents should have been started. This demonstrates that the platform is capable of delivery of multicast FIPA-ACL messages |
| boot | {agent-name} | Tells an agent with the name specified to simply bootstrap and then exit immediately. This demonstrates that the bootstrap mechanism for agents works |
| dfmod | Adds an identical entry to the DF as the dfreg test, but then proceeds to modify it before exiting whilst bypassing the de-registration procedure. This allows the printdir test to be subsequently run to show that the entry was indeed modified | |
| dfreg | Demonstrates that an agent is capable of registering an entry with the DF. It deliberately bypasses the de-registration process so that the printdir test can be used to show that the registration did indeed take place. | |
| dfsearch | Performs a search in the DF for any agents advertising the "test-ontology". To demonstrate positive results some server agents should be started prior to this test | |
| ping | {agent-name} | Sends a ping message to the agent with the name that you specify, the name given should not include the platform name. This test is used to demonstrate that an agent is contactable and that it has bootstrapped properly |
| pings | {agent-name} | Demonstrates that all of the platform services are contactable on their given service names by pinging each in turn. The platform will produce a response in the terminal for each service that received a ping message |
| printdir | Instructs the AMS and DF to print the contents of their directories in there entirity to the terminal window. This is used to demonstrate that registration and de-registration tests have worked as they should | |
| server | {agent-name} | Starts up a server agent with the given name that registers with the AMS and DF and then waits for messages to be sent to it which it prints to the screen. It responds to each message with "i'm here". This agent is used in other testing most notably the agent test. It will wait indefinitely for messages so the term test should be used to end it |
| term | {agent-name} | Tells an agent with the given name to terminate. This is used to gracefully end a test agent that you no longer wish to run. Used often to end server agents that wait indefinitely until they receive a terminate message |
| terminate | Instructs the platform to gracefully terminate. This is the preferred method to get the platform to finish in between tests |
In order to run the SWIG tests a shared library must be built first using the
make file given in the SWIG directory. The same
pre-requistite in that the DBUS_SESSION_BUS_ADDRESS evironement variable must
be set before running any of the tests remains for running the Java agents.
Simialr to the C tests the Java tests require a command line parameter in order
to instruct it which test to run. In order to run these tests they should be
called from the SWIG/Java directory from a terminal as follows:
[SWIG/Java]$ java -Djava.library.path=../ main {args}
This is required so that the test program can find the shared library that
contains the platform code built by the makefile. The tests that the Java agent
is capable of running are given below
| First Param | Second Param | Test Description |
|---|---|---|
| api | Creates and maipulates a FIPA-ACL message structure using only API calls and then prints the results. This demonstrates that the API methods are callable from Java | |
| agent | {agent-name} | Performs the function of the C test "agent" that forms part of the test agent system. Has the same effect as the C version |
| server | Bootstraps the agent platform from within Java |
| Directory | Explanation |
|---|---|
| / | Contains the main source file which is the entry point for the program. Also contains the file platform-defs.h which is the file that contains definitions of all of the C structures that are used throughout the platform and definitions of constants used throughout. This is the central location for all the definitions of the core aspects of the platform, the implementation of the use of this information is given in other files |
| /AMS | Contains the implementaion of the AMS support service |
| /API | This is the implementation of the API which includes all of the publicly accessible functions that are offered through the SWIG interface. The filenames have been chosen to be descriptive of the part of the API that they implement. The two most notable files are agent.c and platform.c that are the files that handle the bootstrap and main abilities of the agent and the platform respectively. |
| /Codec | Implementation of the DBus codec that is used for all communication between the platform and agents. It encodes all of the platform structures so that they can be sent as the contents of messages over D-Bus. All of the functions in DBusCodec.c come in pairs one for encoding and an equivalent for decoding |
| /DBus | Functions that are used as helpers when dealing with the DBus as the transport bus. Packages up some of the commonly rquired procedures that is used by the platform |
| /DF | Implementation of the DF support service |
| /MTS | Implementation of the interaction layer |
| /SWIG | Implementation of thew SWIG component of the solution that allows the API to be called from programming languages other than C. agentPlatorm.i is the interface file that makes the appropraite API functions publicly accessible. The subdirectory Java contains the implementaion of some Java test agents that perform similar functions to the C test agents and demonstrate that the SWIG implementation works. The code can be found in main.java. |
| /Tests | Implementation of the tests that are used to demonstrate the platform and produce the test results given in the dissertation. Information on how to use these tests is given in Running The Tests. tests.c contains the test driver that determines which test should be run. Tests that are not agents but are just used to manipulate the platform structures are found in the same file, all tests that are actually agents that connect to the platform can be found in test-agents.c |

Substituiary Locomotion Spell
Treguna Mekoides and Trecorum Satis Dee
Substitutiary locomotion mystic power
That's far beyond the wildest notion
It's so weird, so feared, yet wonderful to see
Substitutiary locomotion come to me.

He's just a thumb.
At the height of my depression, I found the most amazing puppy on the planet. He saved my life and made me a better person. I hope he understands what he means to me. When this photo was taken, he was nameless.
Fresh air, free mind.
I've always loved being outside! In Florida, the beach was my escape. In NYC, it was Prospect Park. In Atlanta, it was Piedmont Park. Now that I'm in Oregon, I explore the Pacific Northwest as often as I possibly can. Always, with Mustard.

You sense the presence of any trap within range that is within line of sight. A trap, for the purpose of this spell, includes anything that w ould inflict a sudden or unexpected effect you consider harmful or undesirable, which w as specifically intended as such by its creator.
Thus, the spell w ould sense an area affected by the alarm spell, a glyph of warding, or a mechanical pit trap, but it w ould not reveal a natural weakness in the floor, an unstable ceiling, or a hidden sinkhole.
This spell merely reveals that a trap is present. You don't learn the location of each trap, but you do learn the general nature of the danger posed by a trap you sense.


In the main window, the structure of the databases is displayed. You can create new objects, delete and edit existing objects if the privileges of the user that you are using on the current connection to the database allow this.
The left side of the main window shows a tree with all servers, and the objects they contain.
The upper right side shows details of the object currently selected in the tree. Some objects might have statistics in addition to their properties, these can be shown if you select the Statistics tab.
The lower right side contains a reverse engineered SQL script. You can copy this to any editor using cut&paste, or save it to a file using Save definition... from the File menu, or use it as a template if you select the Query Tool. If the Copy SQL option is selected, the SQL query will be copied automatically to the tool.
The status line will show you some status information, as well as the time the last action took pgAdmin III to complete.
You can resize the main window, and change the sizes of the three main regions as you prefer. These adjustments will be preserved when you exit the program.
pgAdmin is bandwidth friendly. The status of objects in the browser is only refreshed on request or after changes made with the built-in tools. Be aware that this does not cover changes made via manual SQL or from other users or other clients. It is generally advisable to manually refresh objects before working on them in such environments.
After you have added the desired server(s) to the tree on the left side using the Add server menu or toolbar button, each server will show up under the top node "Servers".
To open a connection to a server, select the desired server in the tree, and double click on it or use Connect from the Tools menu. The connection will be established, and the properties of the top level objects are retrieved from the database server. If you've been connected to that database previously, pgAdmin III will restore the previous selection of database and schema for you. The current situation is saved when exiting the program, so that pgAdmin III is able to restore the previous environment.
Using the menu or toolbar buttons, you can create new objects, delete objects and edit properties of existing objects if the user that you entered when adding the server connection has sufficient privileges. You may find some options grayed out if displaying properties. This means, that the database server you're currently using doesn't support the feature, or that this property can't be changed by design, or that your user privileges won't allow you to change it.

1. The first one(the easiest one) Tell everyone about it!
This will help us get know and get used by others! And this helps CaffeeCoin a lot!
2. The second way is to run a CaffeeCoin node or mine CaffeeCoin
(Running a Node)
Running a CaffeeCoin node helps the CaffeeCoin Blockchain be more decentralised and more reliable!
(Mining CaffeeCoin)
Mining CaffeeCoin helps to verify transactions and create new blocks in the blockchain to ensure that the Blockchain is reliable and secure
by verifying the transactions!
This does not only benefit CaffeeCoin it also benefits the miners, as whenever you mine, you will get paid in CaffeeCoin which
is basically printing money!
3. The 3rd way is by donating to the founders and managers of CaffeeCoin
