{% extends 'base.html' %} {% block title %}Contribute data - Geomancer{% endblock %} {% block content %}
Do you have a data source you'd like to add to Geomancer? We built this as in an open, extensible platform, so anyone can contribute. If you know how to program in Python, you can add your own data source using the instructions below. Otherwise, post your request to our Google Group.
First, fork the geomancer repository. This requires a GitHub account.
Next, follow the setup instructions to get Geomancer working on your local machine.
BaseMancer
classGeomancer implements a base class that establishes a pattern for setting up a new data source. Simply inherit from that class and override a few properties and methods like so:
from geomancer.mancers.base import BaseMancer class MyGreatMancer(BaseMancer): name = 'The best mancer ever' machine_name = 'best_mancer' base_url = 'http://lotsadata.gov/api' info_url = 'http://lotsadata.gov' description = 'This is probably the best mancer ever written' def column_info(self): return 'woo' def search(self, geo_ids=None, columns=None): return 'woo' def geo_lookup(self, search_term, geo_type=None): return 'woo'
Detailed information about how the responses from these methods should be structured as well as two example mancers can be found in the Github repository.
GeoType
(optional)
Does your mancer offer data that relates to geographic areas that are not
currently offered by Geomancer? This is also built in an extensible way. Each
GeoType
is implemented as a subclass that expects
a few static properties to be overridden:
from geomancer.mancers.geotype import GeoType class WizardSchoolDistrict(GeoType): human_name = 'Wizard school district' machine_name = 'wizard_school_district' formatting_notes = 'Full name of a school district for wizards and witches' formatting_example = 'Hogwarts School of Witchcraft and Wizardry'
More details on how to implement a new GeoType
can be found
here.
The basic configuration options for Geomancer exist in app_config.py
.
Add the import path to the module where you wrote your mancer and you should start seeing it as an option when you run the app.
MANCERS = ( 'geomancer.mancers.census_reporter.CensusReporter', 'geomancer.mancers.usa_spending.USASpending', 'geomancer.mancers.my_mancer.MyMancer', )
If the API that you are using requires an API key, you can add that into app_config.py
like so:
MANCER_KEYS = { 'wizard_school_district' : 'biGl0ngUu1dT4ing', }
The key should (i.e. wizard_school_district
) should match the value you used for the machine_name
of your mancer class.
If you'd like to share your work with the rest of the world, submit a pull request!


Outcome of this project was published as a conference paper in IEEE BigData2019 Conference in December, 2019, Los Angeles, USA.
The rapid development of low-cost sensors, smart devices, communication networks, and learning algorithms has enabled data-driven decision making in large-scale systems. However, the development platforms for such Internet of Things (IoT) applications and collecting the data in a cohesive, yet simple manner is not very well understood. MIT App Inventor is an open-source, user-friendly interface to develop mobile applications and has been used by over ten million users worldwide. We have added IoT capability to the MIT App Inventor platform where people can build applications using various sensors and IoT platforms such as Raspberry Pi and Android Things to collect the data through mobile applications. This poster paper presents a realization of easy to program IoT applications in the mobile application space with a focus on collecting data from the connected sensors. We have integrated the Android Things platform with the MIT App Inventor and introduced the existing MIT App Inventor community to the IoT based App development. This integration allows not only the seasoned developers, but also the novice developers to make interesting IoT applications with minimal programming knowledge.
The MIT App Inventor is an open-source app-building platform that allows users to drag-and-drop visual objects to create an application that can run on the Android system as a means of democratizing mobile app development. Application behavior is provided by piecing together blocks in a visual blocksbased programming language. MIT App Inventor is used by students, teachers, developers, hobbyists, and entrepreneurs to develop apps for collaboration, productivity, personal use, recreation, learning, social good, and community activism. The ease of use of the system as a tool for making has contributed to its success and over 10 million people have used MIT App Inventor worldwide to create 43 million projects.
The Android Things is a lightweight version of Android published by Google that can be flashed onto different hardware prototyping boards, such as the Raspberry Pi 3, Intel Edison, and NXP Pico i.MX7D. Android Things extends the core Android framework with additional APIs that allow apps to integrate with new types of hardware not found on mobile devices. Apps for embedded devices bring developers closer to hardware peripherals and drivers than phones and tablets. By integrating the IoT capabilities of Android Things with MIT App Inventor, we eliminate the need for heavy and complex programming code by simply enabling the visual and interactive block-based drag and drop programming tools to create IoT applications. In the case of input sensors connected to the Raspberry Pi device or any other Android Things supported device, the data from these sensors can be relayed to the phone app or to an external storage device for the post or real-time data analysis purposes to obtain useful insights to make decisions. The integration of these two technologies (MIT App Inventor and Android Things) with a simple, userfriendly environment enables a larger audience of developers to create applications that can collect a vast amount of data in the fast-growing IoT space.
We have created an App Inventor extension for Android Things. This extension includes the following four components that can be easily configured in an MIT App Inventor project. The main component necessary is the ‘AndroidThingsBoard’ component. The devices connected to the board can be modeled using the peripheral components such as ‘AndroidThingsGPIO’ (Android Things General Purpose Input Output), ‘AndroidThingsPWM’(Android Things Pulse Width Modulation) and ‘AndroidThingsTemperatureSensor’(Temperature Sensor Component supporting Android Things).
This is a non-visible MIT App Inventor component that models the Android Things Board. It is responsible for relaying messages between the IoT devices connected to the board and the MIT App Inventor app. In order to set up an Android Things board, first, we need to flash the Android Things Image to the board, and this is a one-time setup on the board that we need to complete. Depending on the type of board we are planning to use, we need to download and install the correct flash image. Make sure the board is connected to WiFi because otherwise, the IoT devices will not be able to communicate with the phone app.
The official MIT App Inventor distribution provides an Android app called the Companion App that supports realtime testing during development. In a similar vein, we have introduced a Support App that bridges MIT App Inventor and the Android Things standard development kit libraries to provide essential communication support between the mobile app and the Android Things supported device such as Raspberry Pi. A unique identifier is needed to tether the phone app and the device. For simplicity, this support app generates that identifier, which is cached in a file and reused to avoid having to enter a new identifier every time the framework is restarted. We use the Android Things App Inventor Support App to facilitate the sending and receiving of messages to and from MIT App Inventor apps that use the Android Things components
To set up an Android Things Board as an MQTT broker, we recommend installing Mosquitto [7]. To control the devices and sensors connected to the Android Things Board via the Internet with this approach, the board must have a public IP address. Alternatively, we can use one of the public MQTT brokers, such as iot.eclipse.org. If we wish to secure the payloads, we must use SSL ports
Before using the AndroidThingsBoard component, you need to initialize the component with certain board parameters such as “identifier”, “hardwarePlatform,” “messagingHost,” “messagingPost” to make sure the board and the corresponding App Inventor component will work together as shown in the Figure 1.
Similarly, the client components such as the AndroidThingsGPIO, AndroidThingsPwm, and the AndroidThingsTemperatureSensor must be registered. For example, Figure 2 shows the most important properties, events and methods of the AndroidThingsTemperatureSensor component.
One straightforward applications is monitoring the temperature of a room or any place remotely, which has many advantages. Temperature data can be collected using temperature sensors that are connected to the device. Similarly, we can monitor the temperature of the home, and turn on and off the air-conditioning or the heater as needed, remotely, only when required. The functionalities of the Application is to monitor the temperature. Figure 3 shows the Android Things temperature monitor Configuration. On the mobile phone, we introduce a button (Button1) that will start the temperature monitoring process. Once that button is pressed, the Android Things Temperature sensor will start monitoring the temperature. In the next step, as shown in Figure 4, we have introduced a simple process to change the color of the phone screen based on the temperature reading, which is shown in the Figure 5 We have introduced two temperature thresholds such as “Hot Threshold” and “Cold Threshold”. The mobile phone user can change the threshold values as desired. If the temperature value is higher than the user entered threshold value for Hot Temperature, then the mobile phone screen background color will change to the red color. If the current temperature reading from the sensor is below the cold threshold value, the screen background color will change to the blue color, and if the sensor reading value is in between the hot and cold temperature threshold values, then the phone background color will change to green.
This research paper presented in the IEEE BigData Conference shows the novel design and implementation of Android Things integration with the MIT App Inventor and demonstrated the viability of the technology using a sample app. The integration of the two technologies enables Interest Driven Innovation in the fast-growing IoT space. The simplicity and user-friendliness of using MIT App Inventor components make IoT applications to empower ordinary people to become innovators. As a result of that, a new frontier of innovators will emerge as their interests grow on solving problems, finding suitable data driven solutions to problems they face in their day to day lives. More information on these IoT sensors is available at http://thilankam.github.io/ mit-app-inventor.
The purpose of this project was to control the pins of the Raspberry Pi easily using an android device. To achieve this, I created two MIT App Inventor components: the “RaspberryPiServer” and the “RaspberryPiPinClient”. The “RaspberryPiServer” models the RaspberryPi board, whereas the “RaspberryPiPinClient” models Raspberry Pi’s low level Digital Interfaces known as GPIO (General Purpose Input and Output) pins using a higher level programming abstraction offered by MIT App Inventor utilizing the MQTT protocol.
As an example, these two components allow anyone to create a simple DIY home automation Raspberry Pi project such as turning any appliance in their home on or off remotely using their android device at a fraction of the cost of many commercial products available today. The coding required on App Inventor is shown on the left hand side and the setup required on the Raspberry Pi is shown on the right hand side.
The main code repo for this project is appinventor-sources. However, the integration of Raspberry Pi required me to create two additional repos to facilitate MIT App Inventor on the Raspberry Pi and to circumvent licensing issues due to a library used on the Raspberry Pi side of things.

SNOW FALLING ON CEDARS A film review by Steve Rhodes Copyright 2000 Steve Rhodes RATING (0 TO ****): ** 1/2
SNOW FALLING ON CEDARS is a silent movie. Well, not exactly, but director Scott Hicks (SHINE) does rely chiefly on tableaux to tell the story, which is based on David Guterson's well-respected novel.
This isn't quite as hopeless as it might seem, since Robert Richardson's breathtaking cinematography of the Pacific Northwest during the snowiest winter in decades is nothing short of astounding. Couple this with gorgeous settings and richly evocative music, and you've got a movie that's a real treat for the eyes and the ears. Your mind, however, will not be equally engaged.
Cutting back and forth in time and locale, Hicks only confuses the viewers.  The people inside the dimly lit cedar tree are now closer to the age of consent than 10. Another time, we witness hand-to-hand combat on American shores only to find that it's Germany instead. If these visual slights of hand served some purpose it might be different, but they don't.
At the center of the story is a fascinating trial. Kazuo Miyamoto (Rick Yune), a Japanese-American who fought just a half-decade earlier in the trenches of World War II, is on trial for the murder of a local fisherman, who died recently under what appear to be mysterious circumstances. Since Kazuo was the last person at the crime scene, he is accused of the murder. In a xenophobic town in which European-Americans distrust Japanese-Americans, and vice-versa, Kazuo is immediately assumed guilty by most of those not of Japanese ancestry.
One man who does eventually come to Kazuo's aid is the local newspaperman, Ishmael Chambers (Ethan Hawke), since he and Kazuo's wife, Hatsue Miyamoto (Youki Kudoh), were long-time childhood sweethearts. Hawke (BEFORE SUNRISE), who is an accomplished actor, isn't able to do anything with his part in this picture because of the restrictions placed upon him by the director. Hicks strategically places Ishmael in each scene and then has him look as stoic as possible while saying absolutely nothing. Stone statues have more warmth.
Although the trial sequences are mesmerizing, Hicks uses them only as a glue to hold the rest of the story together. The script by Hicks and Ronald Bass devotes most of the movie to the long background material on the years before the trial. As we spend long minutes observing native flora, the movie takes on the same remote and dispassionate feel found in THE THIN RED LINE. Whenever the trial starts to build a little momentum, Hicks cuts back to the past so that young Ishmael and Hatsue can stroll along the beach some more.
The star of the trial is the wise, but aging, defense attorney, Nels Gudmundsson played with panache by Max von Sydow. Nels's hands shake, he has trouble remembering his questions, but he puts his heart and soul into the case. Whether it will be enough to save his client is, nonetheless, questionable.
Paced faster and with much of the extraneous material pruned back, SNOW FALLING ON CEDARS could have been an outstanding motion picture instead of merely a handsome one. Posturing as an art form works for painters, but the technique isn't suitable for an action medium. Hicks should have given Hawke some meaningful lines and let him out of his straightjacket. Together they could have fashioned something wonderful.
SNOW FALLING ON CEDARS runs a long 2:06. It is rated PG-13 for disturbing images, sensuality and brief strong language and would be fine for teenagers.

Introduction
About QorIQ Layerscape Software Development Kit (LSDK)
LSDK is a complete Linux kit for NXP QorIQ ARM-based SoCs and the reference and evaluation boards that are available for them.
It is a hybrid form of a Linux distribution because it combines the following major components to form a complete Linux system.
- NXP firmware components including
- PPA, a resident EL3 privilege secure firmware for ARMv8A.
- NXP peripheral firmware components for DPAA1, DPAA2, and PPFE.
- NXP boot loaders. Two are offered:◦U-Boot, based on denx.de plus patches.
- U-Boot, based on denx.de plus patches.
- UEFI, based on Tianocore.
- NXP Linux kernel, based on kernel.org upstream plus patches.
- NXP added user space components.
- Ubuntu standard user space file set (user land), including compilers and cross compiler.
The use of Ubuntu user land is what makes LSDK a hybrid. It is not Ubuntu per se because it uses an NXP kernel, but it still uses Ubuntu user space files. This is possible because NXP ARM SoCs are standards-based so programs like bash and thousands of others run without being recompiled.
The benefit of using Ubuntu user land is the easy availability of thousands of standard Linux user space packages. The experience of using the LSDK is similar to using Ubuntu, but the kernel, firmware, and some special NXP packages are managed separately.
LSDK also permits easy access to the individual components that either originate or are modified by NXP. Source code is made available via git.


I was thinking about Twill and web testing and operational tests. After a couple emails with Titus Brown about Twill and his recent WSGI support. And I thought that Twill could be nice for some operational and functional tests, and that it would be even better if you could also run them in a browser like Selenium. Selenium is nice as well, but automating it fully seems really really hard. If you want to test websites that require Javascript to function, well... but I'm okay limiting myself. Similarly Twill itself requires some limiting. And, to be practical, it wouldn't be that hard to create something that could run Selenium code without a browser. But Twill is more compact.
Anyway, I created some rough code. You can look at a demo, or check out the svn repository at http://svn.colorstudy.com/home/ianb/twill_js/
Hmmm... My opinion on this mixed. Competition is a good thing, but at the same I can see lots of opportunity for collaboration. With so many testing tools around, it would be fun to do some kind of "Testing Tools Summit" to share ideas and compare notes. Maybe host it in conjuction with a "Python Web Frameworks Summit". :-)
Do you think Selenium is just too complicated to get going or do you think it's just lacking documentation? What are your top 3 three things you'd like to see (or see fixed or see changed) in Selenium, that weren't there?
-Jason "The guy who wrote Selenium" Huggins.
I don't have any real problem with Selenium. In part I did this because it amused me, but also the ability to do automated/non-browser evaluation of the script is important. Like I said, it wouldn't be that hard to write a non-browser Selenium interpreter (maybe that even exists), but I just wrote it in this direction.

Well, as long as I'm on the topic, this is what I like less about Selenium:
- There's a lot of up-front complexity that isn't very important, and little things (like how do you start your own test suite) are not as blindingly obvious as they should be.
- Last time I looked at it -- and this was in discussion, so it may have been resolved -- there wasn't many ways to create higher level abstractions of your scripts, to keep the line count down and cut out repetetive parts. (Note that the featureset provided by my code is, if anything, worse on that regard)
- The names are really long.
- The table is a bit too constrained. Everything must take 0-2 arguments.
- Interactive development seems like it would be hard -- I am not likely to type Selenium commands out easily. Interactive creation of Twill in the browser seems quite reasonable (not implemented, of course).
But all that said, none of those were the reasons I wrote this, nor are they the kind of substantive reasons I would or wouldn't choose Selenium.
# Ian Bicking
Yeah, I do think the HTML table syntax can be limiting sometimes. I'm starting to prefer Twill's syntax of splitting on whitespace, instead of table tags. If you write your tests in Mozilla Composer or Word or Excel, Selenium's tables thing is not a big deal. I know some people also use PHP or JSP to convert code into the table tags on the fly. Since I spend my whole day in TextPad on Windows, I think I'd rather have a clean syntax that looks good in plain text. I'll blame Selenium's original design on the fact that it started as a JavaScript implementation of the FIT framework, which relies heavily on HTML tables for its test syntax.
I think both Twill and Selenium are little too terse in its syntax. Instead of this (twill syntax):
# Not too exciting... go /examples/twill_js/test.html fv 0 age 10 fv 0 name Ian echo Get ready for the submit! submit 0 notfind NOTHING follow back code 200I'd rather have a HyperTalk-inspired syntax like the following:
-- Not too exciting go to /examples/twill_js/test.html type 10 into field with name "age" type "Ian" into field with name "name" print "Get ready for the submit" click "submit-me" assert page is not null go back assert response_code is 200I think the HyperTalk-esque syntax has the same "non-programmer friendliness" that Selenium table tests or Twill tests have, but in a more literate and self-documentating syntax. However, there are now decades of experience with English-like languages like AppleScript, HyperTalk, (and even COBOL), and most "real programmers" hate those languages, even though in this case, I think it would make sense-- a domain specific language for automating actions on a web page. Most programmers would rather have Ruby, Perl, JavaScript, Python, or Java, etc. But anyway, that's a whole 'nother debate, and I don't think I have time to (re)invent the HyperTalk programming language to improve the readibility of my Selenium tests, even though I'd love to do it. I throw this idea out there just in case someone else in web-land stumbles upon this thread and has a free year to implement it for me, and agrees that HyperTalk was the coolest language ever. :-)
With that tangent aside, I'm thinking that the logical next steps for Selenium are:
- To make the HTML table-tag aspect of Selenium tests optional. Split on whitespace instead, like Twill.
- More fully support straight JavaScript test files, for the moments when you need loops, conditionals, functions, etc...
- More fully embracing browser extensions like Selenium Recorder... Browser extensions let Selenium run "outside" of the security sandbox Selenium usually lives in. And being "outside" that box would let users do interesting things like testing or automating any site on the net (not just the the local host where Selenium was installed.) The key words for this are "cross site scripting" and "same origin policy"... and it trips up lots of new users of Selenium.
Since Selenium "lives in the browser", you could do (or hopefully soon do) interactive inspection and test creation by using cool tools like JavaScript Shell (http://www.squarefree.com/shell/) to play with a page and create tests. Also, interesting browser extensions like Selenium Recorder (http://seleniumrecorder.mozdev.org/) are making it even easier to get up and running with Selenium and creating your first tests...
Anyway, 'tis interesting times to be a web developer and software tester. Lots of cool stuff is getting created these days in this space.

Hi, Jason,
thanks for your positive comments on twill's syntax: I make it up as I go, and (thus far) have mostly been just happy when something works. I do try to keep the syntax simple as opposed to easy, because one of the major use cases for twill is its use by non-programmers; what programmers find easy is often not so simple. Note also that the twill syntax is very closely linked to Python code; for example,:
go heretranslates directly to:
go('here')This is a very convenient feature for Python programmers and several users seem to be using it this way.
On a more general note, I'm a bit boggled by Ian's ability to work on 80 billion different projects. At least for the short term, I don't have the capacity to work on a JavaScript version of twill; nor am I sure that it'd be an unambiguously good thing to have, unless it were somehow possible to keep the languages virtually identical. Maybe it is, maybe not. However, it may be that Selenium and Twill can get together and have unnatural spawn in the future: perhaps a twill-inspired version of Selenium with pwettier syntax?
Also, let me say: twill aims low. I want a simple, solid way to script and test Web sites in a fairly black-box-ish manner. It honestly shouldn't be too much work to get there, and I bet the future will be in recorders and/or test automation technology rather than twill-ish languages. After all, who cares what language the test uses, if the computer can write it for you?
Finally -- Grig Gheorghiu and I have proposed an Agile Development tutorial for PyCon. As you no doubt know, Grig is a huge proponent of Selenium. We will certainly feature both twill and Selenium in our tutorial. No doubt our febrile imaginations will come up with plans for some orcish melange of twill and Selenium, and I have a hard time resisting a good hack...
--titus
p.s. "--" for comments is ungodly! long live '#'!
p.p.s. just kidding ;).
I bet the future will be in recorders and/or test automation technology rather than twill-ish languages. After all, who cares what language the test uses, if the computer can write it for you?
I disagree, I think recordings can never understand what matters and what doesn't, and the result is too fragile. And once you've done it, if it's not expressed as some at least vaguely sensible language, then it is uneditable. That language might be in markup, or might not, but I think it really has to be a "language", not just a literal recording. Recorders are nice, still, they just aren't complete by themselves.
# Ian Bicking
"Recorders are nice, still, they just aren't complete by themselves."
I agree. Test recorders are kind of like of Ruby on Rails's generators and scaffolding... They both get knocked alot, however, they are very useful when you consider them "the starting point" and not the final production-ready result. Test recorders lower the barrier to entry into the testing framework's language or API--- that, and the kids love 'em. :-) My past experience with macro or test recording is with SQA Robot by Rational (now IBM) and with Microsoft Excel's built in macro utility. In both cases, I used recording to generate a simple, single working script... then went on to edit that raw test into a far more robust and "programmed, not recorded" test suite. The recorders gave me working code from step one, which I then manipulated as needed.
Well, maybe it's a matter of degree. At some point I doubt there will be a need for language innovation -- but recorders can get much better...
We'll see ;).
--titus
# sureshvv
Quoting Benji York from gmane.comp.web.zope.devel:
Brian Lloyd has developed zope.testrecorder, a cross-browser (IE, Firefox, Safari) JavaScript app that records browser events (clicking, entering text, etc.) and test assertions (this text box should contain this text, this checkbox should be unchecked, etc.) and renders the captured events as either an HTML Selenium test or a doctest using zope.testbrowser. It can be installed as a product into Zope 2 or as a Python package in Zope 3.
The rendering framework is pluggable and it's pretty easy to add new rendering options for other testing systems (twill, etc.).
The testrecorder is currently in "beta" form, but is very handy, so if anyone wants to use/market/improve/add tests for it, go ahead. :) Get it via Subversion at svn://svn.zope.org/repos/main/zope.testrecorder/trunk
It is very cool.

The people were discovered in a lorry on a Stena ship that was sailing from Cherbourg
by Brynmor PattisonUp to 16 people have been found alive in a truck that was bound for Ireland.
The people, who are believed to originally be from Asia, were discovered in a lorry container on a Stena ship that was sailing from Cherbourg in France and due to arrive at Rosslare Harbour in Co Wexford this afternoon.
The ship is set to dock at 3pm and those onboard will be met by gardai and emergency services, RTE reports.
It is understood those discovered in the truck were taken to the lounge area of the ferry and are in relatively good health.

5 great shows to watch on Netflix this week
by Kim Renfro- Every week, Insider puts together a list of great shows on Netflix you could watch.
- This week we recommend “The Great British Baking Show: Holidays,” “The Crown,” “I’m With the Band: Nasty Cherry,” “Shine On with Reese,” and “The Kominsky Method.”
- Visit Insider’s homepage for more stories.
Netflix has more original series and classic TV shows than the average person can keep up with. To help parse through the options, Insider is here to recommend five shows that are actually worth your time this week.
Starting things off is a special Christmas-themed set of episodes of everyone’s favorite baking competition.
‘The Great British Baking Show: Holidays’
Liam and Andrew on “The Great British Baking Show.”
Netflix
Seasons: 2
Episodes: 4
The beloved UK reality series “The Great British Bake Off” (called “The Great British Baking Show” for US audiences) has released its special seasonal episodes.
On two new episodes of baking competition, fan-favorites from old seasons return to complete a triad of challenges that are all holiday-themed. If you want to get into the mood for Christmas a bit early, turn to these new episodes of “The Great British Bake Off” today.
‘The Crown’
Seasons: 3
Episodes: 30
A new season of “The Crown” just premiered on Netflix, so now is the time to catch up with the inspired-by-true-events series. For this season, a whole new cast was brought on to play the Queen and her loved ones and advisers.
The 10 new episodes feature Oscar-winning actress Olivia Colman, Helena Bonham-Carter, plus two ex-“Game of Thrones” stars: Tobias Menzies and Charles Dance.
‘I’m With the Band: Nasty Cherry’
Seasons: 1
Episodes: 6
This is a new reality series from Netflix in which pop star Charli XCX does her own twist on the “Making the Band” series. The show follows the UK singer and songwriter as she helps an up-and-coming pop/punk band called Nasty Cherry try to navigate the unpredictable process of breaking through as a new music group.
‘Shine On with Reese’
Seasons: 1
Episodes: 9
“Shine On” was originally a DirecTV series, but now all nine episodes are streaming on Netflix. This is yet another unscripted series, but in more of a talk-show format. Actress Reese Witherspoon meets with a different icon in each episode, and her star-studded guest lineup includes director Ava DuVernay, singer Pink, music legend Dolly Parton, and more.
‘The Kominsky Method’
Seasons: 2
Episodes: 16
The second season of “The Kominsky Method” premiered last month with little fanfare, but this series (created by “King of Sitcoms” Chuck Lorre) is one of the most consistently pleasant shows on Netflix at the moment. It’s fun, poignant, and packed with talent. If you’re in the mood for an easygoing comedy, “The Kominsky Method” is a good place to start.
For more Netflix options, read Insider’s list of the best movies you can stream this week.


Distributing Android apps
Objective
In this section, you will learn about Google's Android Market program requirements and the steps you must take to publish an app to the Market.
Contents
The diagram below illustrates the steps involved in publishing to the Android Market. Though, if you look carefully you'll see that two of the steps verify the work you do in other steps. The steps are:
-
Register with the Android Market
-
Generate a keypair and certificate
-
Verify your keystore
-
Build and sign your app
-
Verify your app is signed correctly and ready to be uploaded
-
Upload the app and publish it to the Market
Register with the Android Market
To publish apps in the Android Market, you will need a Google account. This could be your personal Gmail account or you could register a new account for your company. Then, you must sign up for the Android developer program by visiting developer.android.com. Google charges a one-time $25 fee, which in their words, "encourages higher quality products on the market (e.g. less spammy products)."
To sell apps (charge, not give them for free), you'll need to register for a Google Checkout account as well. Visit http://market.android.com/publish/, click on Edit profile, and then click "Setup a Merchant Account at Google Checkout." You'll need to supply various bits of business information, including banking and legal details. Setup and approval is relatively quick. Once you're registered, you'll be able to set prices for your app in various currencies and participate in Google's In-App Billing program.
Generate a keypair and certificate
You'll need to digitally sign your app before uploading it to the Market. To do this, you'll need to generate a keypair and certificate. You'll do this once for each app you publish by using the keytool command, which is supplied with the Android SDK. In generic form, the syntax is:
keytool -genkey -v -keystore path/file_name -alias alias_name -keyalg RSA -validity 11000
There are two bits in that you'll need to supply. The first is the path/file_name which you use to specify the keystore in which your keypair and certificate will be stored. Each keystore file can store many unrelated certificates. So typically, you'd put the keystore file in your home (your user) directory so that it's reasonably secure and backed up with the rest of your data. The alias_name is the label that identifies which keys you're storing (and which you'll be retrieving later). Set that something specific to your app.
For example, if you were to execute the keytool command from your home directory for an app named HelloWorld, you might enter:
keytool -genkey -v -keystore android.keystore -alias helloworld -keyalg RSA -validity 11000
The key algorithm (keyalg) must be RSA for the Android Market and the validity period must be 11000 (days) or longer. That works out to 25 years or so, which is the validity period that the Android Market system requires. They want to make sure you can provide upgrades to your app for a very long time.
You will be prompted for your name, company name, and locality information, which is used to build the certificate. You'll also be prompted for a password. Make sure you record or remember that password! You'll need to use this same certificate to sign your code each time you update your app. If you don't have that password, you won't be able to release an update. Check out the Market sometime. You're sure to find "new" apps that should have been upgrades. In many cases, those are from developers who forgot their keystore passwords and had to release a whole new version. In doing so, their old users never get update notifications and the app probably loses some of its userbase.
Verify your keystore
Because the certificate is so crucial to publishing (and later updating) your app, we teach "verification" as a separate step. Once you've generated your keypair and certificate, you should verify your keystore to ensure that the algorithm is correct, validity period is sufficient, and that you remember your alias and password correctly. Again, you'll do so with the keytool command:
keytool -list -v -keystore path/file_name
You'll be prompted for your password. The command will list each of the aliases contained in the file and its associated certificate information. Make sure that contact info is correct and make sure the certificate is valid for 25 years or more from the date it was created.
Build and sign your app
Once you've generated your certificate, you can build and sign your app. From the menu as shown, choose Distribute - Android to bring up the dialog box shown in the second screenshot.
In this dialog, you enter the path to where you want the final APK file stores, the path to your keystore file, the keystore password, and the alias associated with your app's certificate. Click Finish and Titanium Studio will build your app and sign it with your certificate (rather than the development certificate used during testing).
Verify your app is signed correctly and ready to be uploaded
Before uploading, you should verify that the APK file was created and signed correctly. You'll do so with another Android SDK command-line tool. At the command prompt, enter:
jarsigner -verify -verbose path/yourapp.apk
where path/yourapp.apk is the path and file name associated with your app's APK file. You should see the "jar verified" message at the end of a long list of APK file contents. Now you're ready to publish your app.
Upload the app and publish it to the Market
Visit https://market.android.com/publish/Home and log onto your Android Market account. Click Upload Application to begin the publishing process. Be prepared with the following required assets:
-
Minimum of two (2) screenshots of your app
-
In one of these sizes: 320 x 480, 480 x 800, 480 x 854, 1280 x 720, 1280 x 800
-
24 bit PNG or JPEG (no alpha)
-
Full bleed, no border in art
-
You may upload screenshots in landscape orientation. The thumbnails will appear to be rotated, but the actual images and their orientations will be preserved.
-
-
One (1) high resolution app icon – 512 x 512, 32 bit PNG or JPEG
-
Title (your app's name)
-
Description, 4000 characters max. Make this "SEO friendly" as it will help drive downloads of your app.
-
Promo text, 80 characters max. This is the brief summary that appears in some listings pages. Be as SEO friendly as you can in the space permitted.
-
Application Type and Category, which you'll choose from the Market's predefined lists.
-
Content Rating – you'll choose from High, Medium, Low, and Everyone. This rating helps filter inappropriate apps from those who don't want to see such content.
-
Contact information – you'll need to provide some way for customers to reach you. This information will be shown to potential buyers.
You should read, and then you'll have to check the boxes indicating you agree to the Market's terms and conditions. There are many additional assets you could provide, such as videos and larger promotional graphics. You can set a price and currency options for your app if you've set up a Google Checkout account.
Capturing screenshots with DDMS
As noted above, you'll need at least two screenshots to publish your app. You can crab those with DDMS. With your Android device connected or emulator running, open ddms and select your device in the top-left pane. Choose Device, Screen Capture. Save two representative screenshots to your desktop or home directory. Close ddms. Disconnect your device following your operating system's procedure for safely removing USB devices.
Summary
In this section, you learned how to publish your Android app. You learned how to generate the keypair and certificate required to sign your app. You saw how to build and sign your distribution-ready APK file. And finally, you examined the Android Market requirements and learned how you'd upload and publish your app.

CS 111- Introduction to Computer Science
Homework #13 |
Due: Friday 4/28 at the beginning of classHex (Part 1)
0. Learn the game of Hex:
1. Implement HexState: Implement a class HexState.java
according to this specification. This
will likely be your most significant and challenging homework assignment of the
semester, so start early. Note:
- Read the documentation carefully. Your integer constants for
PLAYER2, NONE, and PLAYER1
need to be -1, 0, and 1,
respectively. Don't just read the method summaries. Some have
additional necessary specification details beyond the summary tables.
- It is easiest to represent Hex's
rhombic hexagonal grid board as a square grid, using a 2D array of
the aforementioned integer constants. Let grid cells be adjacent if
they are vertically adjecent, horizontally adjacent, or diagonally adjacent
along the diagonal where the row and column both increase/decrease together.
- The most challenging method you'll implement will be the
getWinner method. Determining the winner will require you to
devise an algorithm that is related to your 2D maze solving algorithm.
Think of it this way: Player 1, seeking to connect the top row to the bottom
row, wins if there is an unbroken path of connected pieces running from the
bottom row to the top row (or vice versa). Finding that path is like
finding a maze path from any player 1 piece on the bottom row through
passages of same colored pieces and reaching the top row. All player 2
pieces and empty spaces can be considered walls of the maze. If
there's a solution to this player 1 "maze", player 1 has won.
Similarly, player 2 seeks a path along their own pieces from the leftmost
column to the rightmost column. Study the maze code and adapt it as
necessary (e.g. don't forget that you'll have 6 directions to search).
- The constructor that copies another HexState must make a "deep
copy". That means you need to not merely copy the reference
to the given state's board. You need to allocate a new, independent 2D
array and copy the contents over to the new object. Without a correct
implementation of this constructor, the undo function will not work.
- The toString method is the second longest method you'll
implement, but there are full details of the implementation in the
specification.
2. Test HexState: Test your HexState class using the provided
Hex.java Graphical User Interface (GUI). Usage: "java
Hex". Single-click onto
an empty hex grid cell to play a piece in that spot. Press "u" to undo a
move. You can also use the "Game" menu to undo a move, restart a game,
start a game with a different size board, or go to a website where people play
Hex online. Note that playing with this GUI prints a transcript of play to
the standard output that will be useful
for testing your text-based HexGame.java in the next homework
assignment.

Struct R1Interval
An R1Interval represents a closed, bounded interval on the real line. It is capable of representing the empty interval (containing no points) and zero-length intervals (containing a single point).
struct R1Interval
;
This class is intended to be copied by value as desired. It uses the default copy constructor and assignment operator.
Constructors
| Name | Description |
|---|---|
this
(lo, hi)
|
Constructor. If lo > hi, the interval is empty. |
Methods
| Name | Description |
|---|---|
addInterval
(y)
|
Expands the interval so that it contains the given interval "y". |
addPoint
(p)
|
Expands the interval so that it contains the given point "p". |
approxEquals
(y, max_error)
|
Returns true if this interval can be transformed into the given interval by moving each endpoint by at most "max_error". The empty interval is considered to be positioned arbitrarily on the real line, thus any interval with (length <= 2*max_error) matches the empty interval. |
contains
(y)
|
Returns true if this interval contains the interval 'y'. |
empty
()
|
Returns an empty interval. |
expanded
(margin)
|
Returns an interval that has been expanded on each side by the given distance "margin". If "margin" is negative, then shrink the interval on each side by "margin" instead. The resulting interval may be empty. Any expansion of an empty interval remains empty. |
fromPoint
(p)
|
Convenience method to construct an interval containing a single point. |
fromPointPair
(p1, p2)
|
Convenience method to construct the minimal interval containing the two given points. This is equivalent to starting with an empty interval and calling AddPoint() twice, but it is more efficient. |
getCenter
()
|
Returns the center of the interval. For empty intervals, the result is arbitrary. |
getDirectedHausdorffDistance
(y)
|
Returns the Hausdorff distance to the given interval 'y'. For two
R1Intervals x and y, this distance is defined as
h(x, y) = max_{p in x} min_{q in y} d(p, q) .
|
getLength
()
|
Returns the length of the interval. The length of an empty interval is negative. |
interiorContains
(y)
|
Returns true if the interior of this interval contains the entire interval 'y' (including its boundary). |
interiorIntersects
(y)
|
Returns true if the interior of this interval intersects any point of the given interval (including its boundary). |
intersection
(y)
|
Returns the intersection of this interval with the given interval. Empty intervals do not need to be special-cased. |
intersects
(y)
|
Returns true if this interval intersects the given interval, i.e. if they have any points in common. |
isEmpty
()

Using async functions means that you can try-catch next
.
This example adds a .status
to all errors:
js
app.use(async (ctx, next) => {
try {
await next();
} catch (err) {
err.status = err.statusCode || err.status || 500;
throw err;
}
});
The default error handler is essentially a try-catch at
the very beginning of the middleware chain. To use a
different error handler, simply put another try-catch at
the beginning of the middleware chain, and handle the error
there. However, the default error handler is good enough for
most use cases. It will use a status code of err.status
,
or by default 500. If err.expose
is true, then err.message
will be the reply. Otherwise, a message generated from the
error code will be used (e.g. for the code 500 the message
"Internal Server Error" will be used). All headers will be
cleared from the request, but any headers in err.headers
will then be set. You can use a try-catch, as specified
above, to add a header to this list.
Here is an example of creating your own error handler:
app.use(async (ctx, next) => { try { await next(); } catch (err) { // will only respond with JSON ctx.status = err.statusCode || err.status || 500; ctx.body = { message: err.message }; } })
Error event listeners can be specified with app.on('error')
.
If no error listener is specified, a default error listener
is used. Error listener receive all errors that make their
way back through the middleware chain, if an error is caught
and not thrown again, it will not be passed to the error
listener. If no error event listener is specified, then
app.onerror
will be used, which simply log the error if
error.expose
is true and app.silent
is false.

You can apply 3 kinds of transformations to a value which is to be substituted for a variable: crunching, chomping and splitting. They always occur in that order.
The transformations work around delimiters. Delimiters are the semantic bounds of the "words" in your value. You can use any character (except the null character, which you cannot use in execline scripts) as a delimiter, by giving a string consisting of all the delimiters you want as the argument to the -d option used by substitution commands. By default, the string " \n\r\t" is used, which means that the default delimiters are spaces, newlines, carriage returns and tabs.
(The forstdin command is a small exception: by default, it only recognizes newlines as delimiters.)
You can tell the substitution command to merge sets of consecutive delimiters into a single delimiter. For instance, to replace three consecutive spaces, or a space and 4 tab characters, with a single space. This is called crunching, and it is done by giving the -C switch to the substitution command. The remaining delimiter will always be the first in the sequence. Crunching is off by default, or if you give the -c switch.
Crunching is mainly useful when also splitting.
Sometimes you don't want the last delimiter in a value. Chomping deletes the last character of a value if it is a delimiter. It is requested by giving the -n switch to the substitution command. You can turn it off by giving the -N switch. It is off by default unless mentioned in the documentation page of specific binaries. Note that chomping always happens after crunching, which means you can use crunching+chomping to ignore, for instance, a set of trailing spaces.
In a shell, when you write
$ A='foo bar' ; echo $A
the echo command is given two arguments, foo and bar. The $A value has been split, and the space between foo and bar acted as a delimiter.
If you want to avoid splitting, you must write something like
$ A='foo bar' ; echo "$A"
The doublequotes "protect" the spaces. Unfortunately, it's easy to forget them and perform unwanted splits during script execution - countless bugs happen because of the shell's splitting behaviour.
execline provides a splitting facility, with several advantages over the shell's:
#!/command/execlineb -S1 define -sd" " ARG1S $1 blah $ARG1Sand $ARG1S will be split using the space character as only delimiter.
 If a substitution command is given an empty delimiter string (by use of the -d "" option), the splitting function will try to interpret the value as a sequence of netstrings, every netstring representing a word. For instance, in the following command line:
$ define -s -d "" A '1:a,2:bb,0:,7:xyz 123,1: ,' echo '$A'
the echo command will be given five arguments:
However, if the value is not a valid sequence of netstrings, the substitution command will die with an error message.
The dollarat command, for instance, can produce a sequence of netstrings (encoding all the arguments given to an execline script), meant to be decoded by a substitution command with the -d "" option.

Torque 2D - Particles Tutorial
In this tutorial, you'll learn how to create particle effects in Torque 2D (T2D). Particle effects are commonly used for things like explosions, rain, smoke, and lots of other cool special effects. With practice, you'll be able to use the T2D particle builder to create some really amazing visual effects. To be exact, a 'particle effect' is a group of similar graphics that combine to make an interesting visual effect. Particle effects are generated automatically by a set of parameters that can be edited in Torque 2D. They also move automatically according to a similar set of parameters.  Another example would be rain, which might be made of a bunch of raindrops that move from the top of the screen to the bottom.
To
prepare for this tutorial, you need to have additional particles and assets currently not in the T2D install. Next, run Torque 2D and load the TutorialBase
project (if it's not already loaded) by choosing Open Project...
from the file menu and selecting games/TutorialBase/project.t2dProj.
Then, create a new scene. Finally, save this new scene as "ParticleTutorial".
The Torque 2D particle system is extremely versatile and includes a multitude of features. This allows you to create, effectively, an infinite number of cool effects. When dealing with something that has this many options, it's usually good to have an idea of what you want to create before you start working. For this tutorial, we'll be making a simple explosion that consists of fire shooting out in all directions with a puff of smoke in the center.
To see some examples of particle effects, open the Particle Effect section in the Create Tab. In there, you'll see many examples. When you hover over them with the mouse, you can see them animate. These particle effects can be dragged into the Scene View if you want to see them in action. When you are done viewing them, you can select them by clicking on the center of the effect and pressing the Delete key.
To
start working on our new effect, drag the first entry, newEffect.eff,
onto the Scene View. It starts out emitting a "Test
Texture" graphic by default. In order to start editing its
properties, go to the Edit tab and open the Particle Effect
section. Note that if you click on the graph icon on the left of this
section's label, it will open the graph editor rather than the
Particle Effect section itself. Also, in order to get a good
view of the Edit tab, you may want to drag its left border
further to the left so that you can read all of the properties.
Before you dive into making an effect, let's talk about a couple of important particle concepts in Torque 2D: 'effects' and 'emitters'. A particle 'effect' is the whole particle effect that we save off, including one or more emitters. An 'emitter' is a component of a particle effect which will generally create one type of particle. For example, in this tutorial the fire will be created by one emitter, and the smoke by another. The particle 'effect' will be the combination of these two emitters. This technique of combining multiple emitters can make some really mind-blowing particle effects.
First, Type "Fireball" into the Create Emitter text box and press the plus sign next to it. Then, click the big “Delete This Emitter” button on the default test emitter. A new Emitter subsection appears in the Particle Effect section. We're still not seeing anything in the Scene View, but that's about to change. In the Emitter subsection, find the Image dropdown, which contains all the available sprites in the project, and select particles1ImageMap. Now you can see some tiny fireballs shooting out in a circle. Remember, you can zoom in and out of the Scene View with the '+' and '-' keys if you want a better look.
So now we've created our 'emitter' that is spraying out 'particles': the fireballs. Already this effect is pretty neato, but it's definitely not the explosion we're looking for.  For another, we don't want them shooting out in this strange pattern. Before going on, press the Save Effect button and name the new effect "simpleExplosion.eff". Remember to use this save button whenever you want to save your particle effects... simply saving a scene that contains a particle effect will not save the particle effect in it!
We'll cover the properties shown in the Particle Effect and Particle Emitter sections later. For now, we're going to explore the real powerhouse of T2D particle system... the graph editor. We want to edit the graph of our emitter, so click on the graph icon next to the Emitter - Fireball label. The dialog that pops up is the graph editor, which is used to edit our particles' properties over time. If you don't understand what that means, you will by the end of this tutorial.
To see a list of emitter properties that you can access with the graph, click the Current Field dropdown (as shown in Figure 3). Dang, that's a lot of options! That's why it's a good idea to have some idea what you're trying to create before you jump in. Select Size X Life from the list. This property defines the size of our particles during their lifetime. The point on the far left is the starting point. Click on the point and you'll see its starting value, which is 0,1. The first of these numbers is the time, and the second number is the value. In this case, at time zero (when the particle is created) the Size X Life value is one. Drag that point up and down. You can see your particles change size as you do this. Leave the point at around 0,3.5. If your particle effect is hidden behind the graph editor, move it so you can see it as you work, like this:
Now, we want to make our fireballs get smaller and smaller until they disappear a little ways from the selection box of our particle. To do this, add a new point in the middle area of the graph by clicking there. Drag the point around until the fireballs shrink to nothing just outside the selection box. What you are doing is creating a graph of the particles' size. They start full size at time zero (the 0,3.5 point), then shrink as time progresses to the right.
If you need to delete a point in the graph editor, you can simply right-click on it. Note that you are not allowed to delete the point at time 0 (the far left point).
Right now the fireballs just shoot out and shrink, then disappear instantly... what we really want is for them to fade out quickly at the end, like a real explosion. To do this we'll use the property called Visibility Life, which controls the particles' transparency. In the graph editor Current Field dropdown, select that property. To begin with, create a point in the middle of the graph, then drag it all the way to the bottom. Now drag that point left and right until you can see the particles fading out at the end of their lifespans, but make sure they still last long enough to reach the edge of the selection box. This makes the particles fade gradually throughout their life, but what we really want is for them to stay at full intensity until about halfway through their life, then fade out. All we have to do is create a new graph point between the two points you already have, and drag that point straight up to the top of the graph.  It stays that way until halfway through its life, then it fades out to nothing. If you have trouble seeing this effect, close the graph editor and zoom into your particle effect with the '+' key.
Okay, the effect is starting to look pretty cool, but we wanted an explosion, not a continuous spray of fire. To change this, we're going to edit some effect properties, as opposed to emitter properties, which is what we have been editing. Scroll up to the main Particle Effect section and open the graph. Select Quantity Scale from the Current Field dropdown. This property affects the quantity of particles produced. Raise that initial point all the way to the top of the graph (0, 20). Well, now it's sort of exploding, but it seems to last forever. What we want is to produce this quantity of particles, but only for a second, and then stop. Like you did in the last section, add a couple more points... one at around 0.9, 20 and the other at around 1, 0. When you put in the point at 1,0 you'll see the particle effect stop producing particles... this is because the Quantity Scale goes down to zero, meaning zero particles will be produced. To see your effect continue to generate, change the Effect Mode property in the Particle Effect section to CYCLE. Next change the Effect Lifetime to "2". Now the effect starts over (or 'cycles') every 2 seconds... 2 because the Effect Lifetime is set to 2. Good stuff... the effect is looking a little more like an explosion now!
Let's quickly go through making a second emitter. This will make the explosion look more real by adding smoke and it will also solidify your understanding of using the particle editor. To begin, type "Smoke" into the Create Emitter text box, and press the plus sign to create. You can now scroll down to the Emitter - Smoke section.
First we need an image. Actually, this time lets use an animation... in the Animation property, which contains all the animated sprites from your project, select flamesAnimation. Open the emitter's graph editor and change Size X Base point to around 0,5. Now we can see our smoke animation. Change the Quantity Base point to around 0, 20. Now change the Speed Base point to 0, 0.5 to stop the smoke from rushing away.
For the next property, we're going to use the text boxes on the bottom of the graph editor. Select Speed Variance in the dropdown and try to set it the point to 0, 0.5. It's pretty hard to be exact because the graph is 0 on the bottom and 1000 on the top. These numbers are defined by the Value (Min/Max) properties. Drag the point down to the bottom, then change the Value Max property to "10" and press Enter. Now the graph goes from 0 on the bottom to 10 on the top. Position the Speed Variance around 0, 0.5. Note that if you needed to, you could change the Time (Min/Max) properties to affect the left-to-right scale of the graph also. Keep in mind that you can tailor these values to your liking, and your values may not always be identical to these screens.
The last change to make in the graph editor is to Visibility Life. Put points near 0, 0 then 0.3, 0.3 then 0.7, 0. This makes the smoke fade in and out nicely. If you think the smoke lags behind the explosion, modify your first point's value to something close to 0, 0.1.
Finally, we just need to get rid of that funny ghost shape that always appears in the center. To do this, we'll make the particles come out randomly rotated, instead of always standing up in the same orientation. Simply change the Orientation property in Emitter - Smoke to RANDOM.
Okay, you now have a decent little explosion animation. The best way to learn the particle system is to experiment, so if you want to try making some changes, go for it!
Now that you have some hands on experience with the T2D particle system, you'll have an easier time understanding the various properties available in the Particle Effect section and Emitter subsections of the Edit tab. We'll start with the two that are available in the Particle Effect section.
Effect Mode has four possibilities. All of them except INFINITE use the Effect Lifetime property.
INFINITE: The particle has an infinite lifespan. An infinite mode particle can, however, become invisible if it is no longer generating any visible particles, it just has no built in time frame.
CYCLE: The particle will repeat its life-cycle over and over again. The interval of this repetition is defined by the Effect Lifetime property.
KILL: The effect will delete itself once the Effect Lifetime elapses.
STOP: The effect will stop playing, but will not delete itself, when the Effect Lifetime elapses.
The real meat of a particle effect is in its emitters. Here's a list of all the available settings in the Edit tab:
Image: What image is used for the particle.
Animation: What animation is used for the particle. Either Image or Animation will be used, both cannot be used simultaneously.
Frame: When using a cell based Image this defines which frame to use for the particle.
Type: This tells an emitter where exactly to emit from. POINT emits from the center of the particle effect object. LINEX emits from a horizontal line through the center of the particle effect. LINEY emits from a vertical line through the center of the particle effect. AREA emits from the whole particle effect area.
Orientation: This defines at what angle the particles are emitted. ALIGNED emits at the same angle that the particle effect object is rotated to. FIXED emits them at the angle in the Fixed Angle property. RANDOM emits them at (surprise!) a random angle.
Pivot (X and Y): Define the relative (0 to 1) location of each particle's pivot points.
Force Angle: Used by the 'Fixed Force' graphs. Usually this is used for simulating gravity.
Fixed Aspect: When this is selected, the particle's overall size is defined by their Size X in the graphs, with their Y sizes proportionally scaled. When this is not selected, its Y scale and X scale are determined separately, by 'Size Y' and 'Size X'.
Use Effect Emission: Allows many of the emitters graph values to be set by the overall effect's graphs.
Intense Particles: Makes the particles look fire-like.
Single Particle: Only shows one particle at a time. This is helpful for editing certain properties.
Attach Position: When this is selected, all particles will move with the particle effect object when it is moved. Otherwise, they will trail behind it, pursuing their individual destinies.
Attach Rotation: When this is selected, all particles will follow the rotation of the particle effect object, similar to the Attach Position property.
Rotate Emission: Aligns the emitter with the particle effect object. This is useful for directional particles, like jet flames.
First in Front: Normally when a particle is created, it is seen in front of previous particles that were created by its particle effect. When this is checked, new particles are created behind previously particles.
This tutorial has covered enough to get you started with particles in T2D.  This tutorial did not cover most of the options available in the emitter and effect graphs. For information about these, see the Particle Engine reference document. Also, as mentioned above, one of the best ways to learn about the particle system is just to play with it and see what kind of effects you can come up with. It will be well worth your while to experiment with every property described here and in the Particle Engine document. Enjoy!
