The current version of FireHose has three analytics:
Source code for these is in the tarball directory "analytics". Each sub-directory has code for multiple versions of the analytic, developed in different languages and for different streaming frameworks. Instructions for how to build and run the analytics is given in the Running the benchmarks section.
These are the implementations we currently provide. Over time, as users contribute them, we hope to add more implementations of the analytics, written for various streaming frameworks.
As explained below, each analytic is required to perform a specific computation on the streaming data it receives via a UDP port from one of the stream generators described in the Generators section. The format of the stream is defined by the generator.
An implementation of the analytic should follow the rules discussed below. Most importantly, it should be robust to the possibility it will miss packets in the stream which arrive before the analytic is ready to read them. This is because the generators can be run at high rates, which may outpace the analytic.
If you wish to implement an analytic yourself, or to run a benchmark on your hardware, you are free to implement it in a different manner from the provided code. But you need to perform the computations outlined below and adhere to the following guidelines, at least if you wish to contribute your implementation to the code archive and your performance results to the Results section.
Any additional anayltic-specific rules are discussed below.
This analytic is designed as a simple test of anomaly detection; keys are flagged as unbiased or biased (anomalous) depending on the values associated with an individual key as it appears multiple times. Only a small fraction of the keys are biased.
It is designed for use with the biased-powerlaw generator, which produces packets of datums, each of which is an ASCII text string in the following format:
1000582694,0,1
The first field is a "key", which can be represented internally as a 64-bit unsigned integer. The second field is a "value" of 0 or 1. The third field is a "truth" flag, also 0 or 1.
The computational task for this analytic is to identify biased keys. An unbiased key will have 0 versus 1 values appear with equal probability. A biased key will have 0 versus 1 values appear in a skewed 15:1 probability ratio.
Detection can be performed by keeping track of the values seen for each key, e.g. in a hash table of fixed size (see below). When an individual key has been seen 24 times, the key is labeled "biased" if a value of 1 appeared 4 or less times; otherwise the key is labeled "unbiased". When the decision is made, the answer is checked against the "truth" flag appended to each datum. The large majority of the results will be keys correctly flagged as unbiased (true negative). The other 3 cases are more rare; the count for each of the 4 categories is tallied by the analytic:
The analytic also emits a line of output when a detection event in one of the first 3 categories occurs, in this format, where the last field is the key:
true anomaly = 12345 false positive = 34567 false negative = 67890
Note that due to statistical variation in the way the generator produces random values, for the 3 rare outcomes, true anomalies should mostly be detected, but about 20% of the rare cases will be false positives, with an occasional false negative as well.
The analytic also keeps track of the following statistics which are printed in the following format at the end of the benchmark:
packets received = 999986 datums received = 49999300 unique keys = 85578 max occurrence of any key = 16709489 true anomalies = 34 false positives = 6 false negatives = 0 true negatives = 3220
A reasonable way to implement this analytic is with a hash table that stores a running tally of the values seen for each unique key. Note that the analytic does not know how many times an individual key will appear in the stream, though it need not retain a key after it has been seen 24 times.
Optional command-line switches in the serial reference implementations (C++ and Python):
Additional implementation rules:
This analytic is also designed as a simple test of anomaly detection; keys are flagged as unbiased or biased depending on the values associated with an individual key as it appears multiple times. However the number of unique keys in the stream is effectively infinite for long benchmark runs, so the analytic must decide which keys to store state for.
It is designed for use with the active set generator, which samples from an unbounded range of keys.
In benchmark runs using this analytic, huge numbers of unique keys will be generated, which means it will be inefficient to use a hash table to store all of them, unless some provision for expiring keys is implemented (see below).
Aside from this change in the distribution of keys in the data stream, the computational task of detecting biased keys is identical to the decscription for analytic #1, as is the format of output the analytic should generate. The only exception is that a final output for "max occurrence of any key" is no longer a relevant value to tally.
A reasonable way to implement this analytic is with an expiring hash table that attempts to keep track of values for keys in the active set of the generator, e.g. via a least-recently used (LRU) metric, where the key selected for expiration (removal from the hash table) is the one seen longest ago in the stream. As discussed below, the size of the set of active keys is limited by the generator which can be used by the analytic to age keys efficiently. Note however that the analytic does not knowhow many times an individual key will remain in the generator's active set or appear in the stream, though it need not retain a key after it has been seen 24 times.
Optional command-line switches in the serial reference implementations (C++ and Python):
Additional implementation rules:
This analytic also performs anomaly detection; a set of keys are flagged as unbiased or biased depending on the values associated with an individual key as it appears multiple times. However, the key/value pairs for which the bias detection is done, are derived from state information that must be stored for a different set of keys, namely those which appear in the data stream. This requires two iterations of storage and lookup in different hash tables.
It is designed for use with the two-level generator, which produces packets of datums, each of which is an ASCII text string in the following format:
3929309884956,57364,1
As explained on the doc page for the two-level generator, the first field is an "outer" key (64-bit unsigned integer), the second field (16-bit unsigned integer) is a portion of an "inner" key, and the the third field is a "counter" for how many times the outer key has been emitted.
The first 4 times the outer key is seen, the analytic should store the 4 values. The fifth time the outer key is seen, the 4 previous values are concatenated (right to left, i.e. low-order to high-order) into a new "inner" key, which also becomes a 64-bit unsigned integer. The value for the inner key is the rightmost digit of the value for the fifth occurrence of the outer key, which is a 0 or 1.
The inner key/value pairs are treated the same as the key/value pairs in the first analytic and checked for bias. I.e. when an individual inner key has been seen 24 times, the inner key is labeled "biased" if a value of 1 appeared 4 or less times; otherwise the inner key is labeled "unbiased". When the decision is made, the answer is checked against the "truth" flag, which was the leftmost digit in the value of the fifth occurrence of any of the outer keys which generated this inner key.
The four categories (true anomalies, false positives, false negatives, true negatives) of inner keys, and the format of output the analytic should generate, is the same as described above for the anomaly1 analytic. As in the second analytic, the only exception is the final output of "max occurrence of any key" is no longer a relevant value to tally.
Note that if packets are dropped, the analytic should not try to construct inner keys from incomplete information. The third counter field in the outer key datum can be monitored to insure a specific outer key is seen all 5 times it is needed.
A reasonable way to implement this analytic is with two expiring hash tables, one for outer keys and another for inner keys, and to expire keys from each via a least-recently used (LRU) strategy, as explained for the anomaly2 analytic. Outer keys will be emitted at most 5 times (but may be emitted less); individual inner keys will be encoded in the stream an unknown number of times.

“It was the first time, I realised, that I had ever clearly seen a jazz-band. The spectacle was positively frightening…
“Oh, those mammy-songs, those love-longings, those loud hilarities! How was it possible that human emotions intrinsically decent could be so ignobly parodied? I felt like a man who, having asked for wine, is offered a brimming bowl of hog-wash. And not even fresh hog-wash. Rancid hog-wash, decaying hog-wash. For there was a horrible tang of putrefaction in all that music. Those yearnings for Mammy of Mine and My Baby, for Dixie and the Land where Skies are Blue and Dreams come True, for Granny and Tennessee and You—they were all a necrophily. The Mammy after whom the black young Hebrews and the blond young muffin-faces so retchingly yearned was an ancient Gorgonzola ; the Baby of their tremulously gargled desire was a leg of mutton after a month in warm storage ; Granny had been dead for weeks ; and as for Dixie and Tennessee and Dream Land—they were odoriferous with the least artificial of manures.”

Preparing for a boring flight - XPages.tv offline (Extract media from a feed)
David Leedy provides us with the incredible useful Notes in 9 (a.k.a XPages.tv) tutorials and insights about XPages and Notes. The feed with all the videos is hosted by feedburner. To enjoy them while off the grid you can subscribe to them using iTunes, but that's for Warmduscher .
I'll show you how to use curl and a shell script (easy to translate to a cmd file):
Update: Got a little carried away and used the wrong script, it only did XSLT 1.0, now corrected using Saxon and XSLT 2.0. Thx Ulrich for noticing.
As usual YMMV
I'll show you how to use curl and a shell script (easy to translate to a cmd file):
- First you download the feed:
curl -G -L -o notesin9.xml http://feeds.feedburner.com/notesin9/iTunes
- Run the transformation:
xslt notesin9.xml feedburner2curl.xslt getXPagesTV.sh
(on Windows you would use .cmd) - Make the script executable:
chmod +x getXPagesTV.sh
- Fetch the movies:
./getXPagesTV.sh
#!/bin/bash
notify-send -t 500 -u low -i gtk-dialog-info "Transforming $1 with $2 into $3 ..."
java -cp /home /stw /bin /saxon9he.jar net.sf.saxon.Transform -t -s: $1 -xsl: $2 -o: $3
notify-send -t 1000 -u low -i gtk-dialog-info "Extraction into $3 done!"
(where only the line with "java..." is relevant, the rest is eye candy). The XSLT stylesheet isn't much more complicated (the statements are in one line each, so check the download version to get them right):
notify-send -t 500 -u low -i gtk-dialog-info "Transforming $1 with $2 into $3 ..."
java -cp /home /stw /bin /saxon9he.jar net.sf.saxon.Transform -t -s: $1 -xsl: $2 -o: $3
notify-send -t 1000 -u low -i gtk-dialog-info "Extraction into $3 done!"

<xsl:template match="/">#!/bin/bash <xsl:apply-templates select="//media:content" /></xsl:template>

</xsl:template>
</xsl:stylesheet>
The only interesting part is <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:media="http://search.yahoo.com/mrss/"
version="2.0">
<xsl:output indent="no" method="text"/>

<xsl:template match="media:content">
curl -C - -G <xsl:value-of select="@url"/> -L -o <xsl:value-of select="reverse(tokenize(@url,'/'))[1]"/>
</xsl:template>
</xsl:stylesheet>
reverse(tokenize(@url,'/'))[1]
which I use to get the file name - basically the String after the last /. "tokenize" and "reverse" need a XSLT 2.0 processor.
Update: Got a little carried away and used the wrong script, it only did XSLT 1.0, now corrected using Saxon and XSLT 2.0. Thx Ulrich for noticing.

Technical Part 3 30/07/17
- What a responsive site is, and why responsiveness is important. Resposniveness in webpages allows elements in the page to look different depending on the size of the screen or device through the use of Media Queries. This is important because without this your wepage may look good on a desktop site but on a small screen or mobile device it may look too busy, the font may be too small or certain elements could be off to the side of the screen. Mobile tends to be more linear and simple whereas desktop allows for a lot more to be going on on the webpage.
- What mobile first design is, and why it's important. Mobile-first design is the concept of building your webpage from mobile up to desktop. The term "Progressive Enhancement" sums up this way of thinking as opposed to working from desktop down to mobile with "Graceful Degradation". This way, you are building up your desktop site and adding features to make it more robust than taking away features and stripping ypur product down. Taking the mobile-first design approach is proving to be important as statistics show that a large majority of people are accessing the web more through their mobile devices more than on their desktop. From a technical standpoint it has advantages in that the page only loadswhat it needs to, the bare minimum, rather than loading these features and taking them away. This makes for a much faster and clean experience.
- What frameworks are, and their pros and cons. Frameworks are packges designed to make the process of building a website easier as they have preset stylesheets and grid structures for you to follow. This is great for cross-browser capability, as well as learning good code practice but it can be a bit of a slower learning process as you aren't doing the bulk of it.
- What a wireframe is and why we use it. A wireframe is kind of like a blue print to help you visualise where certain elements are going to be placed on the webpage. In the images below you can see how both my index and blog pages are intended to look in both mobile and desktop versions. This was also useful for me in boxifying all of my elements, shown in green.
- The aspects of your wireframes you found difficult to implement, and why. I found that getting the navigation bar on the right-side (or any side) was particularly hard as most people online who tend to use the Skeleton layout have their navigation bar at the top. I've still got a lot to learn and the framework concept has been hard for me to get my head around.

10 Essential React Interview Questions For Aspiring Frontend Developers
10 Essential React Interview Questions For Aspiring Frontend Developers
Comprehensive React Cheatsheet included at the bottom of this article!
Resources:
All of the code examples below will be included a second time at the bottom of this article as an embedded gist.javascript.plainenglish.io
As I learn to build web applications in React I will blog about it in this series in an attempt to capture the…bryanguner.medium.com
A JavaScript library for building user interfaces Declarative React makes it painless to create interactive UIs. Design…github.com
Also … here is my brand new blog site… built with react and a static site generator called GatsbyJS!
It’s a work in progress
Beginning of the Article:
Pros

- Supports server-side rendering
- Easy migrating between different versions of React
- Uses JavaScript rather than framework-specific code
Cons
- Poor documentation
- Limited to only view part of MVC
- New developers might see JSC as a barrier
Where to Use React
- For apps that have multiple events
- When your app development team excels in CSS, JavaScript and HTML
- You want to create sharable components on your app
- When you need a personalized app solution
Misconceptions about React
React is a framework:
Many developers and aspiring students misinterpret React to be a fully functional framework. It is because we often compare React with major frameworks such as Angular and Ember. This comparison is not to compare the best frameworks but to focus on the differences and similarities of React and Angular’s approach that makes their offerings worth studying. Angular works on the MVC model to support the Model, View, and Controller layers of an app. React focuses only on the ‘V,’ which is the view layer of an application and how to make handling it easier to integrate smoothly into a project.
React’s Virtual DOM is faster than DOM.
React uses a Virtual DOM, which is essentially a tree of JavaScript objects representing the actual browser DOM. The advantage of using this for the developers is that they don’t manipulate the DOM directly as developers do with jQuery when they write React apps. Instead, they would tell React how they want the DOM to make changes to the state object and allow React to make the necessary updates to the browser DOM. This helps create a comprehensive development model for developers as they don’t need to track all DOM changes. They can modify the state object, and React would use its algorithms to understand what part of UI changed compared to the previous DOM. Using this information updates the actual browser DOM. Virtual DOM provides an excellent API for creating UI and minimizes the update count to be made on the browser DOM.
However, it is not faster than the actual DOM. You just read that it needs to pull extra strings to figure out what part of UI needs to be updated before actually performing those updates. Hence, Virtual DOM is beneficial for many things, but it isn’t faster than DOM.
1. Explain how React uses a tree data structure called the virtual DOM to model the DOM
The virtual DOM is a copy of the actual DOM tree. Updates in React are made to the virtual DOM. React uses a diffing algorithm to reconcile the changes and send the to the DOM to commit and paint.
2. Create virtual DOM nodes using JSX To create a React virtual DOM node using JSX, define HTML syntax in a JavaScript file.
Here, the JavaScript hello variable is set to a React virtual DOM h1 element with the text “Hello World!”.
You can also nest virtual DOM nodes in each other just like how you do it in HTML with the real DOM.
3. Use debugging tools to determine when a component is rendering
We use the React DevTools extension as an extension in our Browser DevTools to debug and view when a component is rendering
4. Describe how JSX transforms into actual DOM nodes
- To transfer JSX into DOM nodes, we use the ReactDOM.render method. It takes a React virtual DOM node’s changes allows Babel to transpile it and sends the JS changes to commit to the DOM.
5. Use the ReactDOM.render
method to have React render your virtual DOM nodes under an
actual DOM node
6. Attach an event listener to an actual DOM node using a virtual node
The virtual DOM (VDOM) is a programming concept where an ideal, or “virtual”, representation of a UI is kept in memory and synced with the “real” DOM by a library such as ReactDOM. This process is called reconciliation.
This approach enables the declarative API of React: You tell React what state you want the UI to be in, and it makes sure the DOM matches that state. This abstracts out the attribute manipulation, event handling, and manual DOM updating that you would otherwise have to use to build your app.
Since “virtual DOM” is more of a pattern than a specific technology, people sometimes say it to mean different things. In React world, the term “virtual DOM” is usually associated with React elements since they are the objects representing the user interface. React, however, also uses internal objects called “fibers” to hold additional information about the component tree. They may also be considered a part of “virtual DOM” implementation in React.
Is the Shadow DOM the same as the Virtual DOM?
No, they are different. The Shadow DOM is a browser technology designed primarily for scoping variables and CSS in web components. The virtual DOM is a concept implemented by libraries in JavaScript on top of browser APIs.
- To add an event listener to an element, define a method to handle the event and associate that method with the element event you want to listen for:
7. Use create-react-app
to initialize a new React app and import required
dependencies
- Create the default create-react-application by typing in our terminal
Explanation of npm vs npx from Free Code Camp:
npm (node package manager) is the dependency/package manager you get out of the box when you install Node.js. It provides a way for developers to install packages both globally and locally.
Sometimes you might want to take a look at a specific package
and try out some commands. But you cannot do that without
installing the dependencies in your local
node_modules
folder.
npm the package manager
npm is a couple of things. First and foremost, it is an online repository for the publishing of open-source Node.js projects.
Second, it is a CLI tool that aids you to install those packages and manage their versions and dependencies. There are hundreds of thousands of Node.js libraries and applications on npm and many more are added every day.
npm by itself doesn’t run any packages. If you want to run a
package using npm, you must specify that package in your
package.json
file.
When executables are installed via npm packages, npm creates links to them:
-
local
installs have links created at the
./node_modules/.bin/
directory -
global
installs have links created from the global
bin/
directory (for example:/usr/local/bin
on Linux or at%AppData%/npm
on Windows)
To execute a package with npm you either have to type the local path, like this:
$ ./node_modules/.bin/your-package
or you can run a locally installed package by adding it into
your
package.json
file in the scripts section, like this:
{
"name": "your-application",
"version": "1.0.0",
"scripts": {
"your-package": "your-package"
}
}
Then you can run the script using
npm run
:
npm run your-package
You can see that running a package with plain npm requires quite a bit of ceremony.
Fortunately, this is where npx comes in handy.
npx the package runner
Since npm version 5.2.0 npx is pre-bundled with npm. So it’s pretty much a standard nowadays.
npx is also a CLI tool whose purpose is to make it easy to install and manage dependencies hosted in the npm registry.
It’s now very easy to run any sort of Node.js-based executable that you would normally install via npm.
You can run the following command to see if it is already installed for your current npm version:
$ which npx
If it’s not, you can install it like this:
$ npm install -g npx
Once you make sure you have it installed, let’s see a few of the use cases that make npx extremely helpful.
Run a locally installed package easily
If you wish to execute a locally installed package, all you need to do is type:
$ npx your-package
npx will check whether
<command>
or
<package>
exists in
$PATH
, or in
the local project binaries, and if so it will execute it.
Execute packages that are not previously installed
Another major advantage is the ability to execute a package that wasn’t previously installed.
Sometimes you just want to use some CLI tools but you don’t want to install them globally just to test them out. This means you can save some disk space and simply run them only when you need them. This also means your global variables will be less polluted.
Now, where were we?
npx create-react-app <name of app> --use-npm
-
npx gives us the latest version.
--use-npm
just means to use npm instead of yarn or some other package manager
8. Pass props into a React component
-
props
is an object that gets passed down from the parent component to the child component. The values can be of any data structure including a function (which is an object)
- You can also interpolate values into JSX.
- Set a variable to the string, “world”, and replace the string of “world” in the NavLinks JSX element with the variable wrapped in curly braces:
Accessing props:
To access our props object in another component we pass it the props argument and React will invoke the functional component with the props object.
Reminder:
Conceptually, components are like JavaScript functions. They accept arbitrary inputs (called “props”) and return React elements describing what should appear on the screen.
Function and Class Components
The simplest way to define a component is to write a JavaScript function:
function Welcome(props) {
return
Hello, {props.name}
;
}
This function is a valid React component because it accepts a single “props” (which stands for properties) object argument with data and returns a React element. We call such components “function components” because they are literally JavaScript functions.
You can also use an ES6 class to define a component:
class Welcome extends React.Component {
render() {
return
Hello, {this.props.name}
;
}
}
The above two components are equivalent from React’s point of view.
- You can pass down as many props keys as you want.
9. Destructure props
You can destructure the props object in the function component’s parameter.
10. Create routes using components from the react-router-dom package
a. Import the react-router-dom package:
npm i react-router-dom
In your index.js:
- Above you import your BrowserRouter with which you can wrap your entire route hierarchy. This makes routing information from React Router available to all its descendent components.
- Then in the component of your choosing, usually top tier such as App.js, you can create your routes using the Route and Switch Components

We are here in Georgetown, but we did leave for a short trip and
sailed up to Staniel Cay and back, with a couple of stops in
between. While anchored in Georgetown we had a couple of
fishy friends hang out with us. A couple of remora's found
a home beneath our boat and were there for the 4 days we were at
anchor. They are strange looking fish, and we found out
that they enjoyed eating leftover pasta, dog food, bread, and
most anything else, except lettuce.
Off of Rudder Cay, which is privately owned, there is a small
bay and if you dive down, you can see a statue of a mermaid at a
piano. Rumor has it that the island is owned by David
Copperfield, and that is also who placed the statue, but who
knows. We just know it was fun to snorkel. The
current was ripping when we went to snorkel and it took
everything we had to stay in place. It took Derek three
tries to get down the 15' to the statue and stay in place for
the photos. It was everything Kris could do just to stay
in place against the current to get the photos.
The next stop was at a large sandbar - at least at low tide it
is. It was fun to anchor out in the middle of nowhere
(seas were light), and then go walking on the sand in the middle
of nowhere. We saw lots of starfish and sand
dollars, and Sam enjoyed chasing the ball.
At Big Farmers Cay, we got to swim with a sea turtle, who was
quite large. We swam with some turtles in the Grenadines,
but this guy was much bigger.
Up at Staniel we went out for a nice dinner with "Good Trade"
and their guests, and then headed back to Georgetown with "Good
Trade". Near the end of April is a Family Regatta, which the
locals party and sail their home made local sailboats in races
which will be fun to see.
Dean and Sam go for their daily walk on the beach here, while
Derek does school with Kris. After lunch, then Dean play
volleyball, and Derek goes knee boarding, or other stuff with
the kids around. Kris usually works on boat projects
(trying to get it all spiffy looking to sell), or goes for a
walk or reads a good book.
Life in Georgetown is comfortable, we all get into a nice
routine. Grocery stores and other stores are close by if
something is needed, and most of all - IT IS WARM!
We just can't seen to head north yet, as we get chilled at
nights here, we can't imagine life below 70 degrees.
Hopefully in May when we head back, Florida will be warm enough
for us.

--- layout: post title: "Reader as a contravariant functor" description: "Any function gives rise to a contravariant functor. An article for object-oriented programmers." date: 2021-10-04 5:47 UTC tags: [Software Design] --- {% include JB/setup %}
{{ page.description }}
This article is an instalment in an article series about contravariant functors. It assumes that you've read the introduction. In the first example article, you saw how the Command Handler pattern gives rise to a contravariant functor. The next article gave another example based on predicates.
In the overview article I also mentioned that equivalence and comparison form contravariant functors. Each can be described with an interface, or just function syntax. Let's put them in a table to compare them:
| Name | C# method signature | C# delegate(s) | Haskell type(s) |
|---|---|---|---|
| Command Handler | void Execute(TCommand command); |
Action<TCommand> |
a -> () a -> IO () |
| Specification | bool IsSatisfiedBy(T candidate); |
Predicate<T> Func<T, bool> |
a -> Bool |
| Equivalence | bool Equals(T x, T y); |
Func<T, T, bool> |
a -> a -> Bool |
| Comparison | int Compare(T x, T y); |
Func<T, T, int> |
a -> a -> Ordering |
In some cases, there's more than one possible representation. For example, in C# Predicate is isomorphic to Func<T, bool>
. When it comes to the Haskell representation of a Command Handler, the 'direct' translation of Action<T>
is a -> ()
. In (Safe) Haskell, however, a function with that type is always a no-op. More realistically, a 'handler' function would have the type a -> IO ()
in order to allow side effects to happen.
Do you notice a pattern?
There's a pattern emerging from the above table. Notice that in all the examples, the function types are generic (AKA parametrically polymorphic) in their input types.
This turns out to be part of a general rule. The actual rule is a little more complicated than that. I'll recommend Sandy Maguire's excellent book Thinking with Types if you're interested in the details.
For first-order functions, you can pick and fix any type as the return type and let the input type(s) vary: that function will give rise to a contravariant functor.
In the above table, various handlers fix void
(which is isomorphic to unit (()
) as the output type and let the input type vary. Both Specification and Equivalence fix bool
as the output type, and Comparison fix int
(or, in Haskell, the more sane type Ordering
), and allow the input type to vary.
You can pick any other type. If you fix it as the output type for a function and let the input vary, you have the basis for a contravariant functor.
Consider this IReader
interface:
public interface IReader<R, A> { A Run(R environment); }
If you fix the environment type R
and let the output type A
vary, you have a (covariant) functor. If, on the other hand, you fix the output type A
and allow the input type R
to vary, you can have yourself a contravariant functor:
public static IReader<R1, A> ContraMap<R, R1, A>( this IReader<R, A> reader, Func<R1, R> selector) { return new FuncReader<R1, A>(r => reader.Run(selector(r))); }
As an example, you may have this (rather unwarranted) interface implementation:
public sealed class MinutesReader : IReader<int, TimeSpan> { public TimeSpan Run(int environment) { return TimeSpan.FromMinutes(environment); } }
You can fix the output type to TimeSpan
and let the input type vary using the ContraMap
functions:
[Fact] public void WrappedContravariantExample() { IReader<int, TimeSpan> r = new MinutesReader(); IReader<string, TimeSpan> projected = r.ContraMap((string s) => int.Parse(s)); Assert.Equal(new TimeSpan(0, 21, 0), projected.Run("21")); }
When you Run
the projected
reader with the input string "21"
, the ContraMap
function first calls the selector
, which (in this case) parses "21"
to the integer 21
. It then calls Run
on the 'original' reader
with the value 21
. Since the 'original' reader
is a MinutesReader
, the output is a TimeSpan
value that represents 21 minutes.
As was also the case when I introduced the Reader (covariant) functor, the IReader
interface is just a teaching device. You don't need the interface in order to turn first-order functions into contravariant functors. It works on raw functions too:
public static Func<R1, A> ContraMap<R, R1, A>(this Func<R, A> func, Func<R1, R> selector) { return r => func(selector(r)); }
In the following I'm going to dispense with the IReader
interface and instead work with raw functions.
A ContraMap
method with the right signature isn't enough to be a contravariant functor. It must also obey the contravariant functor laws. As usual, it's proper computer-science work to actually prove this, but you can write some tests to demonstrate the identity law for functions. In this article, you'll see parametrised tests written with xUnit.net. First, the identity law:
[Theory] [InlineData(42)] [InlineData(1337)] [InlineData(2112)] [InlineData(90125)] public void ContravariantIdentityLaw(int input) { Func<int, string> f = i => i.ToString(); Func<int, string> actual = f.ContraMap((int i) => i); Assert.Equal(f(input), actual(input)); }
Here I'm using the (int i) => i
lambda expression as the identity function. As usual, you can't easily compare functions for equality, so you'll have to call them to verify that they produce the same output, which they do.
Like the above example, you can also write a parametrised test that demonstrates that ContraMap
obeys the composition law for contravariant functors:
[Theory] [InlineData(4.2)] [InlineData(13.37)] [InlineData(21.12)] [InlineData(901.25)] public void ContravariantCompositionLaw(double input) { Func<string, int> h = s => s.Length; Func<double, TimeSpan> f = i => TimeSpan.FromSeconds(i); Func<TimeSpan, string> g = ts => ts.ToString(); Assert.Equal( h.ContraMap((double d) => g(f(d)))(input), h.ContraMap(g).ContraMap(f)(input)); }
This test defines two local functions, f
and g
. Once more, you can't directly compare methods for equality, so instead you have to invoke both compositions to verify that they return the same int
value.
They do.
Now that we understand that any first-order function is contravariant, we can see that the previous examples of predicates, handlers, comparisons, and equivalences are really just special cases of the Reader contravariant functor.
For example, Predicate<T>
is trivially isomorphic to Func<T, bool>
. Still, it might be worthwhile to flesh out how other translations might work:
public static ISpecification<T> AsSpecification<T>(this Predicate<T> predicate) { return new DelegateSpecificationAdapter<T>(predicate); } public static ISpecification<T> AsSpecification<T>(this Func<T, bool> predicate) { return new DelegateSpecificationAdapter<T>(predicate); } private class DelegateSpecificationAdapter<T> : ISpecification<T> { private readonly Predicate<T> predicate; public DelegateSpecificationAdapter(Predicate<T> predicate) { this.predicate = predicate; } public DelegateSpecificationAdapter(Func<T, bool> predicate) : this((Predicate<T>)(x => predicate(x))) { } public bool IsSatisfiedBy(T candidate) { return predicate(candidate); } } public static Predicate<T> AsPredicate<T>(this ISpecification<T> specification) { return candidate => specification.IsSatisfiedBy(candidate); } public static Func<T, bool> AsFunc<T>(this ISpecification<T> specification) { return candidate => specification.IsSatisfiedBy(candidate); }
Above are conversions between ISpecification<T>
on the one hand, and Predicate<T>
and Func<T, bool>
on the other. Not shown are the conversions between Predicate<T>
and Func<T, bool>
, since they are already built into C#.
Most saliently in this context is that it's possible to convert both ISpecification<T>
and Predicate<T>
to Func<T, bool>
, and Func<T, bool>
to ISpecification<T>
or Predicate<T>
without any loss of information. Specifications and predicates are isomorphic to an open constructed Func
- that is, a Reader.
I'll leave the other isomorphisms as exercises, with the following hints:
ICommandHandler<T>
to a Func
if you introduce a Unit
value, but you could also try to use Action<T>
.All the contravariant functor examples shown so far in this article series are isomorphic to the Reader contravariant functor.
Particularly, this also explains why it was possible to make IEqualityComparer.GetHashCode
contravariant.
The Haskell base package comes with a Contravariant type class and various instances.
In order to replicate the above MinutesReader
example, we can start by implementing a function with equivalent behaviour:
Prelude Data.Functor.Contravariant Data.Time> minutes m = secondsToDiffTime (60 * m) Prelude Data.Functor.Contravariant Data.Time> :t minutes minutes :: Integer -> DiffTime
As GHCi reports, the minutes
function has the type Integer -> DiffTime
(DiffTime
corresponds to .NET's TimeSpan
).
The above C# example contramaps a MinutesReader
with a function that parses a string
to an int
. In Haskell, we can use the built-in read
function to equivalent effect.
Here's where Haskell gets a little odd. In order to fit the Contravariant
type class, we need to flip the type arguments of a function. A normal function is usually written as having the type a -> b
, but we can also write it as the type (->) a b
. With this notation, minutes
has the type (->) Integer DiffTime
.
In order to make minutes
a contravariant instance, we need to fix DiffTime
and let the input vary. What we'd like to have is something like this: (->) a DiffTime
. Alas, that's not how you define a legal type class instance in Haskell. We have to flip the types around so that we can partially apply the type. The built-in newtype Op
does that:
Prelude Data.Functor.Contravariant Data.Time> :t Op minutes Op minutes :: Op DiffTime Integer
Since the general, partially applied type Op a
is a Contravariant
instance, it follows that the specific type Op DiffTime
is. This means that we can contramap
Op minutes
with read
:
Prelude Data.Functor.Contravariant Data.Time> :t contramap read (Op minutes) contramap read (Op minutes) :: Op DiffTime String
Notice that this maps an Op DiffTime Integer
to an Op DiffTime String
.
How do you use it?
You can retrieve the function wrapped in Op
with the getOp
function:
Prelude Data.Functor.Contravariant Data.Time> :t getOp (contramap read (Op minutes)) getOp (contramap read (Op minutes)) :: String -> DiffTime
As you can tell, this expression indicates a String -> DiffTime
function. This means that if you call it with a string representation of an integer, you should get a DiffTime
value back:
Prelude Data.Functor.Contravariant Data.Time> getOp (contramap read (Op minutes)) "21" 1260s
As usual, this is way too complicated to be immediately useful, but it once again demonstrates that contravariant functors are ubiquitous.
Normal first-order functions give rise to contravariant functors. With sufficiently tinted glasses, most programming constructs look like functions. To me, at least, this indicates that a contravariant functor is a fundamental abstraction in programming.
This result looks quite abstract, but future articles will build on it to arrive at a (to me) fascinating conclusion. Until then, though...

Pantomime provides integration with the futures crate. Futures can be spawned by dispatchers, and their results can be piped to actors.
Futures integration is provided by the futures-support feature, which is enabled by default.
Any Dispatcher can spawn Futures and drive them to completion. The following demonstrates how to do this, using the spawn method.
The pipe_to method can be used to message the result of a Future to an actor. For example:
use pantomime::prelude::*;
// Note: In reality, these would be real futures / actors
let my_actor: ActorRef = ActorRef::empty();
let my_future = future::ok(42);
context.spawn_future(
my_future.pipe_to(my_actor)
);

This file contains information about, and sample data from, the Mawukakan Lexicon, Linguistic Data Consortium (LDC) catalog number LDC2005L01 and isbn 1-58563-337-2.
The Mawukakan Lexicon is the first publication of an on going project aiming to build an electronic dictionary of four Mandekan [Eastern Manding languages of the Mande Group of the Niger-Congo family] languages at the LDC. The other three variants of Mandekan involved are the Bambara or Bamanankan [Mali], the Maninka or Maninkakan [Guinea-Conakry] and the Odienne Jula or Wojenekakan [Cote d'Ivoire]. The lack of written tradition makes such a dictionary project extremely important.
For the dictionary of a small language like Mawukakan (less than half of a million speakers) to be the most useful, it has to combine the linguistic component with a cultural component. The fact that the Mawukakan - English lexicon is coupled with a Mawukakan - French lexicon makes this project a bit more important, given that Mawukakan speakers live mostly in the francophone area of West Africa. This project collected the largest possible amount of data on the Mandekan and the Manding culture and has been made available at LDC for the research community.
The concept of dictionary making at LDC is a revolutionary approach to studying the lexicology of languages that do not have a writing tradition. The project is very original in that it extends the scope of the lexical database beyond a simple list of lexical entries. It suggests that the database includes, in addition to the lexicon itself, anything that can promote a better knowledge of the language and the culture of the Manding people. This includes a collection of audio and video recordings as well as all the written materials available on the language and the culture. By adopting this concept, it becomes easy to preserve small languages like Mawukakan from a speedy death. Apart from creating the best conditions for the popularization and standardization of the writing system of concerned languages, this new approach to lexicology can significantly minimize the research cost on these languages and cultures. Creating the largest electronic database on Mandekan and the Manding culture is more than suitable since the availability of such a database can contribute to increased exposure of all the aspects of both the language and its culture. Because of its electronic nature, updating the database will be an easy and permanent exercise, dependent on the feedback received. This will also reduce the number of fieldtrips Mandekan researchers need to take.
Today's technological breakthroughs makes such objectives not very difficult
to reach. The powerful computers and modern dictionary-making tools available
have transformed lexicology into a more exciting enterprise than before. Our
wish is however that the final product be exploitable by linguists as well as
all other researchers who are interested in the language and the culture of
the Mandenkas. This explains in part our choice of the International
Phonetic Alphabet [IPA] as the main transcription system of Mawukakan. IPA
is the least costly system for transcribing the African languages without a
writing tradition and whose alphabet was defined only at the end of the 1950s,
a period in which most of the colonies in West Africa became independent.
The Mawukakan Lexicon is delivered in two formats. The first is a Linguist's Toolbox project and data file pair. The second is an XML file encoded in UTF-8. Presented below are several entries (as JPEG image files) of an HTML transformation that presents the data in a human readable manner.

DBC pair Coding and Feedback
To give or not to give... And how?
06/19/15
I don't think I'm honest when I give feedback. It's hard to be, honest it is :) I've gotten away with giving just the positive side of the pair session. The part that would (potentially) help my pair improve got swept away under the rug. Partly because I have a hard time building it so that it's not your typical "sxxt sandwich" and partly because I'm afraid my pair will get mad at me.
What to do? In real life I really, strongly believe in giving feedback. I give feedback to anyone, anywhere, anytime ... ahem... anyhow (sometimes a little too directly that is). So why is it hard to give feedback after a DBC pair coding session? An ASK feedback that is (Actionable Specific Kind).
One reason might be the connection solely over the internet. It's already as impersonal as it can be that getting the feedback might be too demoralizing for some (or might indeed offend to the point where they start avoiding you). Like I am very interested to read the feedback I received and I always feel like a little punch in the stomach when someone points out a "to work on" issue.
Another reasons could be that I'm simply afraid to not be liked. You see, I really want to be liked :) So I guess, I just have to keep in mind that, should I connect with someone, the feedback I give shouldn't make much difference in the "connection" factor (as long as it's ASK).To sum it up: keep trying on giving that feedback. You'll get better at doing it ASK-ly. Do it for the sake of your pair - they will like you still, maybe even appreciate the frankness.

In this assignment, you will define Formative Assessment, create a Learning Progression, and explore roadblocks to using Formative Assessment. You will make sense of the complex relationship between assessment and learning. For many of you, this assignment may have profound consequences for your teaching practice or your administrative work. This is a detailed assignment so use your time wisely and make sure that you save time to read and comment on the work of others.
This unit is based on Popham Chapter 12 in the 7th edition. You can complete most of the assignment with the Chapter 12 in the 6th edition but you will need to make some adjustments.
Review the chapter and revise your description of your curricular aim and role from the previous assignment to reflect aspects that are particularly relevant to formative assessment. Try to say a few things about your relevant experience and starting perspective on formative assessment. More than any assignment so far, your aim and role will shape your understanding of the formative functions of assessment. By interacting with your classmates, you should come to see how assessment contexts can either support or undermine the formative potential of assessment.
Formative Assessment means very different things to different people. There are numerous opinions about formative assessment out there. Popham, in Chapter 12, does a nice job summarizing the complex and controversial issues around formative assessment. He also discusses Formative Assessment at this link. You might begin to explore how different assumptions about knowing and learning impact what formative assessment looks like. Here are some other resources you can explore:
Rick Wormeli: Formative and Summative Assessment
Dylan Wiliam: Embedded Formative Assessment
Formative Assessment in a Primary Classroom | KET
Measured Progress: The Formative Classroom
In the textbook, Popham highlights how the term formative assessment has been exploited by commercial firms that are essentially selling drill and practice test preparation materials. These practices raise serious issues concerning evidential and consequential validity. As a developing assessment expert, you should have some well-formed opinions on this topic that reflect your role in education and the domain you teach in.
You should write at least two paragraphs (preferably more) that summarize your stance on formative assessment. You likely will want to start this at the beginning of this assignment and then complete it after finishing the other activities. Please be sure to cite your information and provide links to any additional information you use to complete this assignment.
First, you need to read some information about Learning Progressions. You might want to refer to Popham’s section on “Learning Progressions” in the textbook 7th edition, pages 300-305. The following are additional links to information on “Learning Progressions”:
Popham: All About Accountability/The Lowdown on Learning Progressions
Nichols: What is a Learning Progression? (new, fixed link! 29 June 2014)
Heritage: Learning Progressions: Supporting Instruction and Formative Assessment
Describe what the learning progression might look like for your lesson, with as much detail as you can manage.
You may view two sample learning progressions developed by previous students here (pdf, 100kB).
Discuss the obstacles you might face when implementing your chosen approach to formative assessment. What obstacles might you encounter? Why do you think you would encounter those obstacles? How might you overcome them? As part of your discussion, rank the three most common roadblocks to Formative Assessment in order of relevance within your role and context (Popham, p. 314-315).
Add brief justifications for the Roadblocks to Formative Assessment that you chose as most relevant and the one you chose as least relevant, keeping in mind your role and context.
Review the chapter, assignment, and your peers’ wikifolios. Also, read the Chapter Summary and What Teachers Need to Know. Come up with three big ideas. Number the ideas (1, 2, 3) and list them in order of importance to you, keeping in mind your role and context. Write a brief summary/explanation of each idea where you make it clear why they are relevant to you. These are the BIG ideas of the chapter not the more specific concepts listed above. You should refer to the What Teachers Need to Know…. section and the summary at the end of the chapter. Try to insert your experience and academic domain into this discussion.
Review Popham’s section titled “Alternative Implementation Approaches.” Select one of the three approaches that appears most relevant to your role and context. Indicate why that approach is most relevant with enough detail to show that you appreciate the differences between the three approaches. Then, with as much detail as you can, describe what this would look like in your role and context. You can use these headings for the approach you choose.

FIVE-STRATEGIES APPROACH 1. Clarifying 2. Engineering Activities 3. Providing Feedback 4. Activating Peers 5. Activating Self |
Take the self-check at the end of the chapter. Answer all of the questions without looking up the answers. If you can't answer the items you should go back over that section. Say a few words about the ones you got wrong and why.
Ponder the Pondertime questions. Do so in light of your role and and aspirations and identify the question that is most relevant to you. Write a response to the most relevant question that includes an explanation of why it is most relevant to you. In particular consider how your role and domain impacted the relevance of the questions for you.
Post three brief reflections. You should write a coherent reflection that demonstrates understanding of the concepts and how they related to your curricular aims and context. On your Wikifolio, be sure to label each of the three types of engagement as you present your reflection.
You are advised to begin drafting the reflections while you are working on the Wikifolio, and then to complete them before starting the next assignment. They should serve as a review and help you better connect the ideas of the chapter to your practice.
While you are commenting, you should endorse at least three of your classmates’ Wikifolios for being complete. If your classmate has completed the required Consider the Concepts elements of the assignment, click the box that says Required Elements Completed. If your classmate has completed all of the expertise elements (except for the reflection) click All Elements Completed.
Your own Wikifolios needs to be endorsed by at least one classmate to count towards course completion. If you completed your wikifolio and it was not endorsed by a classmate, email<EMAIL_ADDRESS>As part of reviewing and discussing, promote one (and only one) of your classmates’ Wikifolios as being exemplary from your perspective. Your reference group is whatever set you choose to review. Ideally you should select promote the one wikifolio that is exemplary out of your networking group. Click the box that indicates you wish to mark it as exemplary and indicate what was exemplary about it that helped you understand the chapter concepts.
This does not have to mean it was that best or even most complete. But rather it was an exemplary consideration of the chapter concepts in a way that helped you better understand them. A “leader” badge will be issued for each of the the three sections for the member of each networking group whose Wikifolio gets the most promotions.
Post at least one question as a comment to your classmates and the instructor that this assignment raised for you, given your role and setting. Try to not ask “known answer” yes/no questions. Rather ask questions that can get some discussion started.
Review the wikifolios of your groupmates and find ones that look interesting to you. Engage in discussion with them by posting questions or responding to their questions. Be sure to put responses in the box for responses. If there are multiple responses make it clear which response you are responding to. The goal here is to generate discussion threads that consider how the chapter concepts and considerations take on different meanings for different students.

Guide Algorithms
Guiding Theory
Guide Algorithm Parameters
Guiding Theory
The default guiding
algorithms in PHD2 are well-established and should work well for most
users. Unless you already have some experience with guiding and
understand the basics, you should probably be cautious about changing
algorithms. However, you may have some special circumstances that
require changes or you may simply want to experiment with the different
algorithm choices. The Advanced Dialog settings in PHD2 make it
easy to do that. Each algorithm has a set of parameters that
controls how observed changes in guide star position (star deflections)
are translated into guiding commands that are most likely to restore
the star to its initial position.
Before
discussing the
details of these parameters, it is worth reviewing a little guiding
theory and looking at what these algorithms are trying to accomplish.
Setting aside
adaptive optics devices, which are entirely different, conventional
guiding faces enormous challenges. The problem at hand is how to
move machinery that weighs tens or even hundreds of pounds with a level
of precision that will not cause streaked or oblong stars. This
type of guiding can only hope to deal with tracking errors that are
"slow and steady", not "fast and random." Sources of slow and
steady (correctable) errors include the following:
- Certain kinds of mechanical imperfections in right ascension gears, including those that cause periodic error.
- Smalll errors in the sidereal tracking rate of the mount
- Atmospheric refraction - stars appear to move more slowly as they near the horizon
- Limited kinds of mechanical deflection and flexure - but not differential flexure
- Mis-alignment of the right ascension axis on the celestial pole
So
what isn't included in the above and isn't correctable by conventional
guiding? Unfortunately, it's a very long list, of which a few
are:
- Atmospheric seeing ("turbulence")
- Gear noise, roughness, and vibration
- Differential flexure - relative movement between the imaging scope and the guide scope
- Wind gusts, cable snags, grit in the drive gears
- And lots more...
The
common denominator shared by the guide algorithms is the need to
somehow react to the slow and steady deflections while ignoring the
rest. This is a difficult problem at best because any given guide
star
deflection is likely to have contributions from many of these sources.
And if that isn't hard enough, remember that real-world
mounts are never perfect - so the move you ask for will not be exactly
the move you get. Usually, the most important requirement
for any algorithm is
to avoid over-correcting, wherein the mount is being pushed back and
forth and the guiding never stabilizes. A typical
approach in these algorithms is to apply "inertia" or "impedance" to
the guiding
corrections. That means making corrections that follow a pattern
and are generally consistent with corrections that have been made
before, while being reluctant to make corrections that require a big
change in direction or amplitude. Resistance to changes in
direction is particularly important in declination, where gear backlash
is a common problem. Hopefully, this background will give you
enough insight into the basics of guiding so that the various guiding
parameters used in PHD2 will make sense.
Guide Algorithm Parameters
In
PHD2, the various guide algorithms can be applied to either the right
ascension or declination axes. Most of these algorithms
include a minimum move
parameter. This is used to avoid making guide corrections that
are overly small, are unlikely to have any effect on star shape, and
are mostly due to transient seeing effects. These values are
entered in units of pixels, so you need to think about them in the
context of how large your star images are. The default values
work well for short-to-medium focal length systems, but you may
need to increase them if you are working at long focal lengths and
expect stars to have larger diameters.
The hysteresis
algorithms keep a history of the guiding corrections that have been
made in the recent past, and these are used to help compute the next
guide correction. The hysteresis
parameter, expressed as a percentage, specifies the "weight" that
should be given to this history as opposed to looking only at the
star deflection in the current guide frame. Consider an example
where the hysteresis parameter is 10%. In that case, the next
guiding correction will be 90% influenced by the star movement seen in
the current guide frame and 10% by the corrections that have been made
in the recent past. Increasing the hysteresis value will smooth
out the corrections at the risk of being too slow to react to a
legitimate change in direction. The hysteresis algorithms also
include an aggressiveness parameter,
again expressed as a percentage, that is used to reduce
over-correcting. On each frame, PHD2 computes how far it thinks the mount
should move and in what direction(s) it should move. The aggressivness
parameter scales this. For example, take a case where the star deflection
has been evaluated and a corrective move of 0.5 pixels is warranted.
If the aggressiveness is set to 100%, a guider command will be
issued to move the mount the full 0.5 pixels. But if the
aggressiveness is set to 60%, the mount will be asked to move only 60%
of that amount, or 0.3 pixels. If you find your mount is always overshooting
the star, decrease this value slightly (say, by 10% steps). If you find PHD2 always seems to be lagging
behind the star's motion, increase this by a little bit. A little can
go a long way here.
The ResistSwitch
algorithm behaves much as its name implies. Like the hysteresis
algorithms, it also maintains a
history of past guide corrections, and any change of direction must be
"compelling" in order to issue a reversing guide command. This
is appropriate for declination guiding, where reversals in
direction are both suspect and likely to trigger backlash
in the gears. For that reason, ResistSwitch is the default
algorithm for declination but not for right ascension, where valid
direction reversals are expected. Starting with Release 2.4.1,
two additional parameters are available for fine-tuning the
ResistSwitch algorithm. The first is "aggression", a percentage
amount that controls how much of the computed guide correction will be
issued. Reducing this parameter can help to avoid over-shooting
with mounts that have little or no backlash. The second parameter is a
checkbox labeled "Fast switch for large deflections." If this is
checked, PHD2 will react immediately to a large change of direction
rather than waiting for three consecutive deflections in the new
direction, which is the normal behavior. This can help to more quickly recover
from large excursions in Dec, perhaps caused by wind, cable snags, or
other mechanical shifts The definition of a "large deflection" is
3x the minimum-move value. So if PHD2 is over-reacting to
direction changes, you can tune the behavior with the min-move
parameter or disable the "fast switch" option altogether. It is
worth remembering that "less is usually better" when it comes to Dec
guiding, so don't try to over-tune these parameters.
The LowPass algorithms
also employ a history of recent guiding corrections in order to compute
the next correction. The starting point for the computed move
is the median value of the guide star deflections that have
occurred in recent history. This means that the star deflection
seen in the current guide frame has relatively little impact on
calculating the next move and the algorithm is very resistant to quick changes. But the history accumulation also
includes a calculation to determine if deflections are trending in a
consistent direction. The slope weight
parameter, expressed as a percentage, determines how much influence
this should have in calculating the actual guider movement - it is
there to keep the algorithm from being overly sluggish. If you
set a slope weight of zero, the guide pulse will always be just the
median value of the recent history. If you set a non-zero slope
weight, that median value will be adjusted either upward or downward
based on the recent trend of guide star movements. Because
the low-pass algorithm is so resistant to quick changes, it is probably
most applicable to declination guiding.
The LowPass2
algorithm is a variation of the original LowPass algorithm with
somewhat different behavior. It also maintains a history of
guiding corrections, but the next correction is simply a linear
extension of the commands that have come before it (i.e. a slope
calculation). This continues until a significant change in
direction is seen, at which point the history is cleared. The
algorithm has two adjustable properties: minimum-move and
aggressiveness. Minimum-move has the same effect as it does in the
other guide algorithms, and aggressiveness (percentage) is a way of further
dampening the size of the guide corrections. LowPass2 is a very
conservative, high-impedance algorithm that may be a good choice for
users with good seeing conditions and well-behaved mounts with little or no declination backlash.
