DEEP IMPACT A film review by Matt Williams
RATING: * * 1/2* out of * * * *
The first of the dueling disaster pics has hit! Deep Impact has beat its competitor, Armageddon, by nearly two months. Gunning to be the more thoughtful of the two, Deep Impact does manage to deliver a few thrills, but it is too detached to deliver much more.
The film opens with the discovery of the doomsday comet by an amateur astronomy buff, Leo Biederman (Elijah Wood). As if that weren't enough bad luck, the movie proceeds to segue into a tragic act that has little purpose and virtually no relation to the rest of the film.
But then things get rolling again as the film picks up the action one year later. An MSNBC reporter, Jenny Lerner (Tea Leoni) has stumbled upon the scoop of a lifetime. Thinking she is delving into yet another Capitol Hill sex scandal, she blunders her way into unveiling the government's secret preparations to avoid Armageddon.
President Beck (Morgan Freeman) has been working with the Russians to build the largest spacecraft in history, the Messiah. An international team of astronauts and cosmonauts (Ron Eldard, Blair Underwood, Jon Favreau, Mary McCormack, and Alexander Baluyev) are joined by Apollo pilot Spurgeon Tanner (Robert Duvall) in their mission to divert the comet.
Of course, a disaster flick wouldn't be a disaster flick if it didn't have the mandatory cross-society slice of life. To that extent, we meet Jenny's estranged parents (Vanessa Redgrave and Maximilian Schell, no less), and reunite with the now famous Biedermans, to see how various families cope with the potential end of the world.
Watching Deep Impact, you get the feeling that you're being left out of the loop. There's some interesting information that's going on just underneath the surface, but the film never quite lets you get a good look. Take the pre-apocalypse baby boom for example, or the riots and civil unrest that accompany the harbinger of doom. The movie presents you with conclusions, but never explains the details of the argument. It gives you a synopsis of events, but never makes you feel like you are there.
The pool of talent definitely isn't lacking in the film. However, when you've got Freeman, Duvall, Redgrave and Schell in the background, Tea Leoni and Elijah Wood can't quite compete. To be fair, they do a decent job, but are simply outclassed.
The character writing doesn't help them out that much, either. To further the plot, and raise suspense, several of the main characters in the film are forced to make wincingly bad decisions. These are decisions that no sane man (and few crazy ones) would dare make.
At least the film has some good eye candy to divert your attention. The special effects are good, but not as awe inspiring as they should be. That's probably the result of the recent glut of disaster pictures. After seeing mass destruction in every other movie, one quickly develops a blasi attitude. Still, there are a few impressive scenes.
Overall, Deep Impact isn't by far a perfect disaster film, but it has its entertaining moments. It's nothing to rush out to see, but a good way to pass the time during a matinee.

Domain types creates readability ...and emergent behaviour

Domain Types
Emergent Behaviour
Code Readability
The focus of this article is how readability and maintainability is improved by replacing simple types with domain types. Consequences of introducing domain types is both a closer relationship between model and implementation, and that the domain types establishes a conceptual foundation making it easier to extend and adapt the application for future changes.

- 3. Solution 2: Domain types to the rescue
- 4. Emergent behaviour
- 5. Conclusions
Our investigations take outset in implementing an application with and without domain types. The implementations are easily comparable, and thus provides ample opportunity to reflect and compare.
What is a domain type anyways?? A domain type is a type that cover the information or intent of a phenomenon in the problem domain (i.e. the real life "thing" we are creating software for). The domain type is expressed in the solution domain (i.e. our code). Some times, a domain type is a mere wrapper for say a string
or an int
.  Allot me to show you differently.
1. Describing the problem domain
We are constructing a small program to help assist in creating a static blog. Based on the content of the blog we need to generate navigational documents linking the blog entries together.
We must read in a bunch of documents. Each document is parsed in order to locate one or more tags inserted into the document describing the content of the document. From the collection of tags we mus generate a "tag file" for each tag, containing links to all documents with that tag. In addition, we must generate a file containing links to all "tag files". Finally, we must generate a file linking to all documents of the blog where the link text is the title of the document.
An analysis of our problem domain thus reveals the following nouns:
| Noun | Description |
|---|---|
| Tag | A title |
| Page | A title and a path |
| Document | A text |
| Document tag parser | Parsing documents and locating tags |
| Page generator | Generate html for the navigation pages |
| File reader/writer | A file-reader and a file-write |
| File system document scanner | A scanner to recursively visit directories |
Potentially each of these nouns are to be modelled by its own class. Rather than turning this into an academic exercise, let us investigate how a lot of people would implement this application. It s straight forward to concoct a solution using simple type already provided by our programming language. We call this solution 1.
Then we tweak the code to use domain types while preserving the existing structure. We call this solution 2... I won't be holding my breath waiting for you to applaud the naming!
2. Solution 1: Using simple types
For the first implementation, we will be creating classes, but if possible we avoid modelling the domain. I know I'm the guy leading the pen, and so I can make up any nonsense I want. What I am trying to accomplish, though, is to stay true to the spirit of how many people code.
Here's how we are going to implement the above model
| Noun | Implementation |
|---|---|
| Tag | string |
| Page | Tuple<string, string> |
| Document | string |
| Document tag parser | A class DocumentParser with a parse method |
| Page generator | A class with a method for each page to generate |
| File reader/writer | System.IO.File |
| File system document scanner | System.IO.DirectoryInfo |
Implementing this in a top-down fashion, makes us start at the document reading and parsing. GetTags()
just below traverses the directory structure and for each document reads it and asks a parser to identify the tags. The tags are then accumulated in the tagsCollection
variable and returned.
public class DocumentParser
{
public Dictionary<string, List<Tuple<string, string>>> GetTags(string rootFilePath)
{
var tagsCollection = new Dictionary<string, List<Tuple<string, string>>>();
var di = new DirectoryInfo(rootFilePath);
foreach (var path in di.EnumerateFiles("*.txt", SearchOption.AllDirectories))
{
var fileContent = File.ReadAllText(path.FullName);
var tagsForPage = ParsePage(fileContent, path.FullName);
foreach(var tagForPage in tagsForPage)
{
if(!tagsCollection.Contains(tagForPage.Key))
tagsCollection.Add(tagForPage.Key), new List<Tuple<string, string>>());
tagsCollection[tagForPage.Key].AddRange(tagForPage.Value);
}
}
return tagsCollection;
}
The tags extraction is a private method of the class which uses some secret regex sauce, finds the relevant information
readonly Regex headerEx = new Regex("^#(?<title> .*)");
readonly Regex tagEx = new Regex("... (?<tagname> .*) .*");
Dictionary<string, List<Tuple<string, string>>> ParsePage(string pageContent, string fullName)
{
Dictionary<string, List<Tuple<string, string>>> tagsToPages =
new Dictionary<string, List<Tuple<string, string>>>();
Match headerMatch = headerEx.Match(pageContent);
string title = headerMatch.Groups["title"].Value.Trim();
foreach (Match match in tagEx.Matches(pageContent))
{
string tag = match.Groups["tagname"].Value;
if(!tags.Contains(tag))
tags.Add(tag, new List<Tuple<string, string>>());
tags[tag].AddRange(Tuple.Create(title, fullName));
}
return tags;
}
A site generator will first invoke the DocumentParser
, then call a PageGenerator
and with its output write to the file system. The implementation details are not important as it is a matter of simple traversals over our data-structure and generating HTML. The file writing is equally simple, just a call to File.WriteText()
, and thus also omitted.
Instead, we focus on the type signatures of the page generator. Type signatures tells you a lot about your code and readability in general.
public class PageGenerator
{
public string GenerateAllTagsPage(List<string> tagToUrl) { ... }
public string GenerateAllArticlesPage(List<Tuple<string, string>> pages) { ... }
public string GenerateTagPage(string tag, List<Tuple<string, string>> links) { ... }
}
2.1 Problems with using the simple types.
Did you trawl through all that code? If not, here is a summary of what we have experienced as problems so far. Feel free to revisit the code as you read along.
Type parameter madness
By now, I hope you are growing a bit tired of type definitions like Dictionary<string, List<Tuple<string, string>>>
. See, I always feel a headache is coming on, when I have to juggle around with such long-winded types whilst trying to understand the code that I did not write myself. Constantly, I have to remind myself, what the data components are. Of course, naming is essential here, for example, tags2pages
would be a typical name to describe the keys and values of a dictionary.
Skewed variable- and parameter-names
As code gets refactored or changed, the first thing to erode are the variable names. The types are ensured to match by the compiler. Thus, an important aspect of code readability and navigability, has to do with expressing intention through use of types.
Gnarly interaction with the dictionary
The astute reader may have noticed another issue with the code. The maintenance of the List<>
inside the dictionary. Each time we need to add an element to a dictionary, whose value is a collection of some kind, we need to initialize if absent and do a AddRange
with out values. It's not so much the same code block repeating itself (although it is a violation of the DRY principle), more, it has to do with how the code reads. Its clumsy and gnarly. You want to add an element, yet you are faced, again and again, with having to deal with initialization and adding to lists. Needless to say, this calls for an abstraction too. Let's call it a TagCollection
and define it further below.
3. Solution 2: Domain types to the rescue
The difficult part in this application is not the algorithm with which to extract the tags or generate the HTML, it is the data structures. And those are only difficult to understand since we are using so many simple types, rather than defining types that encompass the problem domain. The traversal of files, parsing using regular expressions or generating HTML is all trivial. Of course, this is not the case for all types of applications and problem domains, but I have yet to see an application that is harder to read when domain types have been used.
The "Solution 1" implementation uses the type string
to hold the following kinds of data
- File path
- Tag
- Page title
- Page url
- Document
Since the page contains two separate pieces of information, a Tuple<string, string>
is used in representing the page (mapping Item1
to the title and Item2
to the page url).
The use of the Tuple
class, I must admit, is a bit of a provocation. In my experience with code Tuple
is actually not used that much, whereas string
is almost always used for representing all kinds of information. I guess the lack of popularity on Tuple
's behalf may originate from the illegible properties Item1
and Item2
. It only takes ten minutes, or maybe a day, before you have completely forgotten what those anonymous properties hold. I have tried this, and changes are that so have you. This feeling of creepiness, the chilling down your spine, this is the very feeling you must recall whenever you see e.g. string
or int
holding all sorts of information within the same application.
Let us first define our domain classes, hereafter evaluate how the core implementation changes.
3.1 The Tag
class
The Tag
class is merely a wrapper for a string. While any string can be supplied to the constructor of Tag
, the intention of the code, is that it be fed only tag strings. For technical reasons uninteresting to this article, spaces must be replaced by _
in the tag name. A validation that tags do not contain spaces would be an appropriate validation in the constructor. It is not always the case that we can add validation logic or add extra functionality to your domain classes. Do not feel bad when writing a simple wrapper class like below. Eventually evolution of the requirements - or refactorings - may find your domain type to be just the place for new code.
public class Tag : IEquatable<Tag>
{
public readonly string Value;
public Tag(string value)
{
Value = value;
}
public override int GetHashCode()
{
return Value.GetHashCode();
}
public override bool Equals(object obj)
{
return Equals(obj as Tag);
}
public override bool Equals(Tag other)
{
if (other == null)
return false;
return string.Equals(Value, other);
}
public override string ToString()
{
return Value;
}
}
Phew! 30 lines of code just to wrap a string! In order to cut the lines of code, it is tempting not to implement the Equals()
and GetHashCode()
methods. But hold back that urge! They are absolutely vital in our program, since tags are used as keys in dictionaries. In a-soon-to-be-release article, will explore the possibilities of building a reusable domain base class in order to significantly reduce boiler plate code as seen above.
3.2 The Page
class
Probably less disturbing to your nerves, is the replacement of Tuple<string, string>
with a domain class. The gut feeling many people have first introduced domain types, is that of doubt and reluctance. They fail to immediately see the benefits of wrapping just one value in a separate class. Most people, luckily, are more welcoming to the thought of wrapping two or more values in a class. At least it is a huge readability boost to access .Title
rather than .Item1
, and .Url
rather than .Item2
. As for the implementation, it is straight forward.
public class Page : IEquatable<Page>
{
public readonly string Title;
public readonly string FilePath;
public Page(string title, string filePath)
{
Title = title;
FilePath = filePath;
}
public override int GetHashCode()
{
return Title.GetHashCode() ^ FilePath.GetHashCode();
}
public bool Equals(Page other)
{
if (other == null)
return false;
return Title == other.Title && FilePath == other.FilePath;
}
public override bool Equals(object obj)
{
return Equals(obj as Page);
}
}
Similar to the Tag
class it is verbose. Luckily the lines are very easily written. Since the Page is not used as a key in any collection, we could omit implementing the GetHashCode
and Equals
methods. I prefer to keep them. If ever we were to use instances of Page
as a key, it would just work out of the box. And when omitted all sorts of surprising behavior and hard to find bugs arise. Also when unit testing (and not using Stateprinter, it is very convenient to have the Equals
so the Assert.AreEquals()
will work :-).
3.3 The PageGenerator
Before going into the code heavy DocumentParser
re-implementation, let's first confirm that we are on the right track by evaluating how the PageGenerator
changes from hieroglyphic-like to plain English readable code.
public class PageGenerator
{
public string GenerateAllTagsPage(List<Tag> tags) { ... }
public string GenerateAllArticlesPage(List<Page> pages) { ... }
public string GenerateTagPage(Tag tag, List<Page> pagesForTag) { ... }
}
Looking at code how readable the code is now almost brings a tear to my eyes. It sure was worth those extra lines of boiler plate code! Comparing with the previous version of the page generator, code has been morphed from a scary looking caterpillar into a beautiful colourful butterfly.
3.4 The TagCollection
class
The last helper class is the TagCollection
class. This class rectifies the reoccurring problem we had when wanting to add an element to our dictionary. Since the value of the dictionary is a List<>
we need to ensure proper initialization on each insert. We could have made this a static method on our main class DocumentParser
. I've seen this done many times over. However, this makes reuse harder in other situations, or make the code seem very artificial when accessing a DocumentParser class solely for the same of some dictionary util method.
public class TagCollection
{
public readonly Dictionary<Tag, List<Page>> Tags = new Dictionary<Tag, List<Page>>();
public void Add(Tag tag, params Page[] pages)
{
List<Page> values;
if (!Tags.TryGetValue(tag, out values))
Tags.Add(tag, values = new List<Page>());
values.AddRange(pages);
}
public void Add(TagCollection collection)
{
foreach (var kv in collection.Tags)
Add(kv.Key, kv.Value.ToArray());
}
}
The implementation just wrap a dictionary, and makes it easy to add one or more pages. As an extra convenience Add
is overloaded to accept a TagCollection
.
Notice that the previous domain types were immutable, this wrapper is not. A long story can be spun over the theme of visibility and control. Rather than exposing the Tags
field of the class, should the class itself implement IEnumerable<KeyValuePair<Tag, List<Page>>
or Tags
could expose the underlying data through a ReadOnlyDictionary
. Our implementation is derived from our needs. We are not making any attempts locking down the data structure. We are merely interested in making the dictionary interaction easy. So we are as mutable as the dictionary itself. Needles to say, other situations may require a different kind of wrapping over a collection type.
After having created my tag collection class, I writing about it here in this article, I could not help but thinking about the class from a generalization perspective. I quickly recognized, that the problem we are solving in TagCollection
really applies to any dictionary holding a List<>
as the value. Hence we can easily change the class into a ManyValuesDictionary<TKey, TValue>
which wrap a Dictionary<TKey, List<TValue>>
and solves this problem once and for all. Having such an implementation at hand, we can consider if we want to create yet another wrapper for this called TagCollection
, subclass it to get a TagCollection
type or if we are content with using ManyValuesDictionary<Tag, Page>
. It really depends on the size of your application and how wide-spread through out it is using a collection of tags.
As I leave it up to the reader to complete the class, I am absolutely certain, that such a reusable construct would never have evolved, had we settled with implementing a helper method for adding elements. Nor, god forbid, if we felt compelled to sticking with the initial implementation with the clumsy add-logic spread all over the code base. You don't have to accept poor code like that!
3.5 The DocumentParser
For the sake of brevity, let us look at only a subset of the DocumentParser
re-implementation using domain types.
public class DocumentParser
{
public TagCollection GetTags(string rootFilePath)
{
var tags = new TagCollection();
var di = new DirectoryInfo(rootFilePath);
foreach (var path in di.EnumerateFiles("*.txt", SearchOption.AllDirectories))
{
var fileContent = File.ReadAllText(path.FullName);
var tagsForPage = ParsePage(fileContent, path.FullName);
tags.Add(tagsForPage);
}
return tags;
}
}
We make the following observations
- The
tags
variable now has a type of its own. - The add-functionality is a simple one-liner call to an
Add()
method.
4. Emergent behaviour
Even for a small example such as this, going through the exercise, I have had two situations of emergent behaviour. The class definitions add words to my vocabulary, and it sets my mind free to do evolve already existing definitions. I believe this to be fully equivalent to the linguistic findings in the human sciences. There many believe, that one cannot think without a language. The more words you have the better are your capabilities for abstract thought and synthesis of new systems, language and thoughts.
Earlier we saw the emergence of the ManyValuesDictionary
. Now we will see emergence from a different perspective.
4.1 Bug fixing the link name creation
As mentioned earlier, the tag names are defined with an _
substituting spaces. Our naïve HTML generation created links by the following code
stringBuilder.AppendFormat("* {0}", tag.Value);
effectively rendering the links with _
separating words in the tag, rather space which is more aesthetic to the eye. We can easily fix this bug with a needlestick type of change - local and not disturbing anything else.
stringBuilder.AppendFormat("* {1}", tag.Value, tag.Value.Replace("_", " "));
It works, but it is not elegant. And certainly, it has nothing to do with OOP. So what are the alternatives? We could extract the code into a method on the generator.
stringBuilder.AppendFormat("* {1}", tag.Value, RinseForLinkText(tag.Value));
...
private string RinseForLinkText(string s)
{
return s.Replace("_", " ")
}
This is already an improvement. But we can do better. The Tag
class is the natural place to put this method, or maybe expose as a property.
class Tag
{
public string Value;
public string LinkText { get { return Value.Replace("_", " "); } }
}
with using the property
stringBuilder.AppendFormat("* {1}", tag.Value, tag.LinkText);
There are several observations to be made here
- The
Tag
class was a natural place to extend with the needed behaviour. It is a natural extension of our "vocabulary". - The code is more readable, we are simply stating
LinkText
rather than focusing on exactly what that means.
That being said, in the general case, there is a dichotomy between the "single responsibility principle" and OOP. The traditional OOP prescribe that an object knows how to fetch and store itself, how to present itself on a GUI etc. The single responsibility principle, prescribes the opposite and would advocate functionality on the html generator dealing with formatting html.
5. Conclusions
- There is no running away from the fact, that the code has become longer. I don't mind that, the extra code is hidden in external files and the extra lines of code are very easy to spew out.
- With the new domain types, we get improved readability. Code is transformed from hieroglyph-like incantation to almost plain English prose
- The domain types enable the "jump to definition" functionality in your IDE. On the domain types you now have a "go to" place for extra functionality, validations, heck, you can even sprinkle with documentation
- Despite the initial judgement call, where we deemed an abstraction over the file system "too academic", eventually I did create said abstraction. A
FileRepository
replacing calls toDirectoryInfo
andFile
. This abstraction enabled us to do unit testing without hitting the hard drive and needing to clean up files. I guess, some times, unit testing can drive you to do domain types as well :-)

Undocumented |
| Instance Variable | _get_url |
Undocumented |
| Instance Variable | _update_url |
Undocumented |
Constructs a connection to a Gephi master server.
The connection object can be constructed either by specifying the `url` directly, or by specifying the `host`, `port` and `workspace` arguments. The latter three are evaluated only if `url` is None; otherwise the `url` will take precedence.
The `url` argument does not have to include the operation (e.g., ``?operation=updateGraph``); the connection will take care of it. E.g., if you wish to connect to workspace 2 in a local Gephi instance on port 7341, the correct form to use for the `url` is as follows:
http://localhost:7341/workspace0


I have been working as a scrum master with remote teams for 2.5 years and during that time I have deviated a bit from textbook Scrum process. If your working with remote teams, especially if you have members of your team who speak different languages you should be familiar with the cost of miscommunication.
Cucumber
There are a few alternatives when it comes to integration testing your app including the built in Rails integrations tests. I prefer being able to write my integration tests in plain English before writing any code. When I first started with Rails, I was also reading a lot of marketing material around personae and user journeys. The core idea is to decide who your ideal customers are and what they want to achieve. Asking these questions around how and why results in much better web apps.
I find that asking why is a core part of writing cucumber features, in a lot of situations, feature requests (tasks) are handed down to programmers who don’t delve deeply enough into why a feature is needed. This is often based on project managers or clients requesting things without themselves asking why its needed. Its also natural to make assumptions so I find writing a cucumber outline really helps me to think things through. On many occasions questions are revealed that lead to better ideas and simpler implementations.
Don’t do planning meetings
My experience working with remote teams is that the traditional planning meeting once per iteration has limited value. If you have multiple remote locations and language barriers, having everyone in a campfire room or Skype chat, can be very painful. I also find thats its very easy for people to forget the points discussed.
Estimate based on complexity
Instead of planning meetings we do ad hoc estimation meetings. In these meetings we ignore implementation details or discussions about which gem to use, we simply focus on how complex the tasks sound. Normally we spend about 10-15 minutes on estimation per week.
Plan with cucumber
Normally a developer will pick up a task and in an ideal world, they would write a cucumber outline before starting to code. At this point they should then proceed with the WHY cycle and try and determine if the task can be de-scoped.
We have taken this in a slightly different direction by turning cucumber outline writing into our planning meetings. We are using Google Drive which is pretty awesome. We are doing plan per feature rather than one big plan it all type meeting.
Collaborative editing – The team can all see the outline taking shape in real time. Readability and clarity of purpose is a real benefit to this.
Inline chat – Being able to chat inside a google doc (in the margins) is really pretty cool.
Native apps – the app for the iPhone and iPad work amazingly well. On a few occasions I have been shopping and at the same time writing an outline. Its really enjoyable to use.
We normally start each document with a Q+A session, sometimes these are copied from campfire or Skype discussions. In short the google doc becomes a dumping ground for any ideas, edge cases, whatever. We include our QA in the process so they know what is integration tested and they know what to expect from the feature when they test it manually.
I normally spend a lot of time discussing ideas with the client, I can dump these conversations in the doc for developer reference.
Does it work
It’s working very well for us. Rework is massively reduced, our cucumber outlines are very readable meaning new developers have a much better source of documentation to reference. We are more Agile, complex features are identified before we start to code.
Planning is focused, we just write cucumber outlines for the tasks planned in the next iteration, although we spend a few hours a week on cucumber outlines, when a developer starts a feature, they can just copy paste the scenarios and start implementing the steps.
Because the user journey is designed outside of the developer flow, managers, BA’s and clients can talk about UX in an open ended way. Developers don’t start a task in PT unless it has an approved cucumber outline.
Pivotal Tracker
I have been a PT devotee for quite a few years now, its light weight and has just enough features to keep me happy. Although its got commenting its not got the formatting and scope of a google document. Its great for light chat, but if the feature is complex and you want pages and pages of text, its not that easy to read. PT is designed to be light weight and I would not change that.
Linking PT to Google Drive
This is pretty easy to do, both Google Drive and PT have good search, so all thats required is to put the PT task number into the google doc file name, it’s also easy to put a link to the google doc inside PT.
That filename reveals a convention we use for naming features in PT.
usba2 = User should be able to
We try and focus as much as possible on naming features in terms of user objectives. This leads to a lot of developer freedom.
The future
We have allocated a lot of Slack time to making this process easier. You might be familiar with some of the PT / Git workflow gems available. Some of these allow you to control PT from the command line and allow git commits to be linked to PT tasks. We have some ideas on this front to integrate Google Drive with PT. The idea is that when you start a PT task from the command line it will automatically download the cucumber outline from google drive and insert it into a file.
Google Drive is stateless
One pain with Google Drive is that documents are stateless, unlike PT where a task goes through a flow until its marked accepted we need a new solution to organise our docs. Currently we are using folders to solve this. This is what ours looks like:
Since both PT and google drive have APIs we might be able to synchronise activity between PT and Drive more with a bit of dev effort.
Business analysts
If you work with a BA or there is a real interest from the business in the user journey then Google Drive might be something to investigate.

This is simply my collection of what I have been attempting to learn of Mandarin Chinese through the year 2020, both during brief attendances at the classroom at Bendigo Senior Secondary College, 40 Gaol Rd, Bendigo, VIC.
I have formatted the material to suit my own learning style and have published this material in the hope that it may be useful for others.
Should this material be found wanting, or otherwise objectionable to the Mandarin teaching authorities at BSSC I will simply take the site down on request.
This material is in no way a course in Mandarin. To learn the language a student really must be guided by a native, qualified language speaker. However, given that the reader is undergoing such instruction, the material I present may be a useful adjunct to the efforts of your native speakers, especially for revision, that being my purpose in writing it.
NB Wherever possible I have used sound produced by native Chinese speakers, but in the absence of such sound I have made my own attempt.

JavaScript expressions can be evaluated as values inside .less files. We recommend using caution with this feature as the LESS will not be compilable by ports and it makes the LESS harder to maintain. If possible, try to think of a function that can be added to achieve the same purpose and ask for it on github. We have plans to allow expanding the default functions available. However, if you still want to use JavaScript in .less, this is done by wrapping the expression with back-ticks:
You can import both CSS and LESS files. Only LESS files import statements are processed, CSS file import statements are kept as they are. If you want to import a CSS file, and don’t want LESS to process it, just use the .css extension:
Content of imported LESS file is copied into importing style sheet and compiled together with it. Importing and imported files share all mixins, namespaces, variables and other structures.
In addition, if the import statement has media queries specified in it, imported content is enclosed in the @Media declaration.
Are some elements in your style sheet proportional to other elements? Operations let you add, subtract, divide and multiply property values and colors, giving you the power to create complex relationships between properties. Operations should only be performed within parentheses in order to ensure compatibility with CSS. Functions map one-to-one with JavaScript code, allowing you to manipulate values however you want.
It is possible to output rules in your CSS which allow tools to locate the source of the rule.
Either specify the option dumpLineNumbers as above or add !dumpLineNumbers:mediaQuery to the url.
You can use the “comments” option with FireLESS and the “mediaQuery” option with FireBug/Chrome dev tools (it is identical to the SCSS media query debugging format).
As an extension to CSS, LESS is not only backwards compatible with CSS, but the extra features it adds use existing CSS syntax. This makes learning LESS a breeze, and if in doubt, lets you fall back to CSS.

| FYS 187-4 - Games and Computation Why Games? |
Brief comments on the recreation, exploration, and observation of art, beauty, and truth of games.
Why do people play, create, and research games? What is it about games that continues to attract the attention of researchers in Artificial Intelligence (AI) and Recreational Mathematics? Here are a few thoughts to spark a larger conversation on why games represent both an important area of cultural study and a foundational pursuit of the understanding of humans and reason.Just as sports offer fun, competitive exercise of the body, games offer fun, competitive exercise of the mind. Party games (e.g. Charades, the Dictionary Game / Balderdash, Pictionary) often exercise skills of creative communication. Trivia games exercise the recall of broad, common knowledge. Many board, card, and dice games exercise our deepest reasoning and memory skills and ability to model those of our opponent.
Although "recreation" is often associated with the word "leisure", leisure often has an aspect of ease or lack of activity, whereas recreation is often defined as "activity done for enjoyment when one is not working". Put another way, recreation is playful work we opt to do. As my mother would say, "Vacation isn't doing nothing. Vacation is doing something different." In our recreational gameplay, we exercise aspects of our humanity (creativity, problem solving, communication, etc.) when we don't need to simply because we enjoy them. As the athlete enjoys the healthy functioning of the active body, the gamer enjoys the healthy functioning of an active mind.
Many games can be thought of as carefully crafted microworlds, inviting gamers to explore the complex terrain that can spring into existence from even simple rules. There are few dice games with simpler rules than those of Pig, yet the boundary between situations where one should roll or hold, continuing or ending one's turn, is like a complex alien landscape with a wave crashing over rolling dunes.
Physicists have long pursued a mathematical model that describes all physical behaviors of our universe. A theory of everything is an eagerly pursued dream. A game is a micro-universe where the rules define the dynamics and the gamer has a hope of playfully unfolding the mysteries of a new world. Gamers are explorers, experiencing discovery and charting new landscapes with each play, formulating hypotheses of how to best navigate the landscape towards the realm of Victory, and empirically supporting and refuting such hypotheses.
Beyond the game-level pursuit of optimality, games can offer insight to the opponent's intellect and personality. We come to know each other better through games.
"If you would read a mans Disposition, see him Game, you will then learn more of him in one hour, than in seven Years Conversation, ..." - Richard Lingard.
As one who cares to know others better, observe how other players play, especially at the meta-level: how they handle victory and defeat, how they treat other players, how they react to risks and rewards, and whether they value other gamers over the game itself as evidenced through gracious words, considerate use of decision time, and a thousand little opportunities to express value for other players. Never win the game at the expense of losing the metagame; play your best at the game while treating other players as precious friends.
A good game design is a thing of beauty, inviting appreciative observation. Artful design gives rise to interesting balances that must be maintained between risk and reward, short-term and long-term ramifications, and cooperation and antagonism with opponents within the game. The simple rules of many deep games (e.g. Go) give rise to patterns of play and reason that have a beauty not unlike a beautiful phrase of music or intricate sculpture. What is even more surprising and delightful in my experience is how one can find morals in games that transcend games and speak Truth. To modify Mark 8:36 for Chess: "For what shall it profit a man, if he shall gain the whole material advantage, and lose his own king?"
Many games offer shallow (and even often good) evidences of winning potential that are not the same as real winning potential. The deep strategist sees beneath the surface advantage to the true utilities within the game, sometimes offering seeming sacrifices for a greater, deeper advantage. Many "economic"-style games offer short-term scoring gain at the expense of long-term scoring gain, rewarding delayed gratification. Discernment of a proper time to value each element of the game is reminiscent of Ecclesiates 3. In jeopardy games, we learn that to win more often means being willing to lose more spectacularly.
The astute observer of games can extrapolate from the truths of these microworlds to the Truths of our world. As we play, we are invited to become Philosopher-Gamers.
If you have also come to appreciate the joy of game recreation, the exploration of game microworlds, and the art, beauty, and truth of games, I would appreciate the opportunity to read and consider your insights as well.

The workhop will be held on November 2019 in The Venetian Macao, Macau, China in the context of the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), one of the largest and highest impact robotics research conferences worldwide.
Manipulating objects autonomously and in unstructured environments is one of the basic skills for robots to support people during everyday life outside industrial cages. However, such a capability is characterized by great complexity especially regarding the processing of sensors information to perceive the surrounding environment.
The study of autonomous manipulation in robotics aims at transferring human-like perceptive skills to robots so that, combined with state of the art control techniques, they could be able to achieve similar performance in manipulating objects.
The great complexity of this task makes autonomous manipulation one of the open problems in robotics that has been drawing a big interest in the community in the recent years. Conventional approaches attempt to reconstruct the scene using 3D vision and compute agrasping pose that attain force closure constraints, or by querying a database of precomputed or learned poses. More recently, grasping has been addressed using end-to-end learning methods showing great performance. However, these methods require robots to perform thousands of trials. For this reason their application is often focused on simple grippers and scenarios in which images are acquired from a top down view. Manipulation with multi finger hands and mobile robots is unfortunately still out of the scope of these techniques due to the problem complexity.
The aim of this workshop is to discuss and present different techniques proposed for addressing the same problem: object manipulation. More than a comparison, this workshop is designed to encourage people belonging to different research fields such as robotics and deep learning to share their approaches, ideas and problems regarding autonomous manipulation.
The following list provides a set of topics (keywords) addressed in the workshop.


ESB begins decarbonising yellow van fleet with 70 full electric vehicles
by By Press AssociationESB Networks has begun decarbonising its yellow van fleet, with the purchase of 70 full electric vehicles.
The Nissan ENV200s will be added to the fleet throughout 2019 and 2020.
It is estimated 170 tonnes of carbon will be offset annually by phasing out diesel in ESB Networks’ small van fleet.
The vehicles will be deployed nationally to replace small diesel equivalents working in the areas of metering and stores.
Richard Bruton, Minister for Communications, Climate Action and Environment, welcomed the move.
“The Climate Action Plan commits to a really significant step up in electric vehicle use,” he said.
“Our public sector must lead by example if we are to persuade the rest of society to make the changes required.
“I welcome that the ESB are committed to a 100% carbon emissions-free fleet and are making a start with today’s announcement.
“It is vital to show leadership in this area.
“This will cut greenhouse gases, improve air quality and demonstrate what can be done to other sectors.”
Paul Mulvaney, executive director, customer delivery, at ESB Networks, described it as a “step in the right direction”.
“We have conducted market research as well as extensive trialling to ensure that we are not compromising daily range nor our load capacity,” he said.
We are delighted to be in the position to begin phasing out our diesel fleet and we will continue to explore the options available to us to increase our commercial EV numbers, as well as reducing our overall carbon footprint across the business.
“We are playing a pivotal role in paving the way for a greener society through an ever-cleaner electricity system, so we want to make sure that we are doing our part across all our operations.”


BIND 9.8.0 is the first production release of BIND 9.8.
This document summarizes changes from BIND 9.7 to BIND 9.8.
Please see the CHANGES file in the source code release for a
complete list of all changes.
The latest development versions of BIND 9 software can always be found
on our web site at
http://www.isc.org/downloads/development.
There you will find additional information about each release,
source code, and some pre-compiled versions for certain operating
systems.
-
The ADB hash table stores informations about which authoritative
servers to query about particular domains. Previous versions of BIND
had the hash table size as a fixed value. On a busy recursive server,
this could lead to hash table collisions in the ADB cache, resulting
in degraded response time to queries. Bind 9.8 now has a dynamically
scalable ADB hash table, which helps a busy server to avoid hash
table collisions and maintain a consistent query response time.
[RT #21186]
-
BIND now supports a new zone type, static-stub. This allows the
administrator of a recursive nameserver to force queries for
a particular zone to go to IP addresses of the administrator's
choosing, on a per zone basis, both globally or per view. I.e. if the
administrator wishes to have their recursive server query <IP_ADDRESS>
and <IP_ADDRESS> for zone example.com rather than the servers listed by
the .com gTLDs, they would configure example.com as a static-stub zone
in their recursive server. [RT #21474]
-
BIND now supports Response Policy Zones, a way of expressing "reputation"
in real time via specially constructed DNS zones. See the draft specification
here:
http://ftp.isc.org/isc/dnsrpz/isc-tn-2010-1.txt
[RT #21726]
-
BIND 9.8.0 now has DNS64 support. named synthesizes AAAA records from
specified A records if no AAAA record exists. IP6.ARPA CNAME records will be synthesized
from corresponding IN-ADDR.ARPA. [RT #21991/22769]
-
Dynamically Loadable Zones (DLZ) now support dynamic updates.
Contributed by Andrew Tridgell of the Samba Project. [RT #22629]
-
Added a "dlopen" DLZ driver, allowing the creation of external DLZ drivers
that can be loaded as shared objects at runtime rather than having to be
linked with named at compile time. Currently this is switched on via a
compile-time option, "configure --with-dlz-dlopen".
Note: the syntax for configuring DLZ zones is likely to be refined in future releases.
Contributed by Andrew Tridgell of the Samba Project. [RT #22629]
-
named now retains GSS-TSIG keys across restarts. This is for
compatibility with Microsoft DHCP servers doing dynamic DNS
updates for clients, which don't know to renegotiate the GSS-TSIG
session key when named restarts. [RT #22639]
-
There is a new update-policy match type "external". This
allows named to decide whether to allow a dynamic update
by checking with an external daemon.
Contributed by Andrew Tridgell of the Samba Project. [RT #22758]
-
There have been a number of bug fixes and ease of use enhancements
for configuring BIND to support GSS-TSIG [RT #22629/22795]. These include:
-
Added a "tkey-gssapi-keytab" option. If set, dynamic updates will be
allowed for any key matching a Kerberos principal in the specified keytab
file. "tkey-gssapi-credential" is no longer required and is expected to
be deprecated. Contributed by Andrew Tridgell of the Samba Project. [RT #22629]
-
It is no longer necessary to have a valid /etc/krb5.conf file. Using
the syntax DNS/hostname@REALM in nsupdate is sufficient for
to correctly set the default realm. [RT #22795]
-
Documentation updated new gssapi configuration options (new option tkey-gssapi-keytab and changes in tkey-gssapi-credential and tkey-domain behavior). [RT 22795]
-
DLZ correctly deals with NULL zone in a query. [RT 22795]
-
TSIG correctly deals with a NULL tkey->creator. [RT 22795]
-
A new test has been added to check the apex NSEC3 records after DNSKEY
records have been added via dynamic update. [RT #23229]
-
RTT banding (randomized server selection on queries) was introduced in
BIND releases in 2008, due to the Kaminsky cache poisoning bug. Instead
of always picking the authoritative server with the lowest RTT to the
caching resolver, all the authoritative servers within an RTT range were
randomly used by the recursive server.
While this did add an extra bit of randomness that an attacker had to
overcome to poison a recursive server's cache, it also impacts the
resolver's speed in answering end customer queries, since it's no
longer the fastest auth server that gets asked. This means that
performance optimizations, such using topologically close
authoritative servers, are rendered ineffective.
ISC has evaluated the amount of security added versus the performance
hit to end users and has decided that RTT banding is causing more harm
than good. Therefore, with this release, BIND is going back to the server
selection used prior to adding RTT banding.
[RT #23310]
-
There is a new option in dig, +onesoa, that allows the final SOA record in an AXFR response to be suppressed. [RT #20929
-
There is additional information displayed in the recursing log (qtype, qclass, qid and whether we are following the original name). [RT #22043]
-
Added option 'resolver-query-timeout' in named.conf (max query timeout
in seconds) to set a different value than the default (30 seconds). A
value of 0 means 'use the compiled in default'; anything longer than 30
will be silently set to 30.
[RT #22852]
-
For Mac OS X, you can now have the test interfaces used during "make test" stay beyond reboot. See bin/tests/system/README for details.
-
BIND now builds with threads disabled in versions of NetBSD earlier
than 5.0 and with pthreads enabled by default in NetBSD versions 5.0
and higher. Also removes support for unproven-pthreads, mit-pthreads
and ptl2. [RT #19203]
-
If BIND has openssl compiled in (the default) and has any permission
problems opening the openssl.cnf file, BIND utilities fail. Currently
ISC is including a patch to openssl in bin/pkcs11/openssl-0.9.8l-patch
but ISC is working on a better solution until openssl fixes this.
[RT #20668]
-
nsupdate will now preserve the entered case of domain names in
update requests it sends. [RT #20928]
-
Added a regression test for fix 2896/RT #21045 ("rndc sign" failed
to properly update the zone when adding a DNSKEY for publication
only). [RT #21324]
-
"nsupdate -l" now gives error message if "session.key" file is not
found. [RT #21670]
-
HPUX now correctly defaults to using /dev/poll, which should
increase performance. [RT #21919]
-
If named is running as a threaded application, after an "rndc stop"
command has been issued, other inbound TCP requests can cause named
to hang and never complete shutdown. [RT #22108]
-
After an "rndc reconfig", the refresh timer for managed-keys is ignored, resulting in managed-keys
not being refreshed until named is restarted. [RT #22296]
-
An NSEC3PARAM record placed inside a zone which is not properly
signed with NSEC3 could cause named to crash, if changed via dynamic
update. [RT #22363]
-
"rndc -h" now includes "loadkeys" option. [RT #22493]
-
When performing a GSS-TSIG signed dynamic zone update, memory could be
leaked. This causes an unclean shutdown and may affect long-running
servers. [RT #22573]
-
A bug in NetBSD and FreeBSD kernels with SO_ACCEPTFILTER enabled allows
for a TCP DoS attack. Until there is a kernel fix, ISC is disabling
SO_ACCEPTFILTER support in BIND. [RT #22589]
-
When signing records, named didn't filter out any TTL changes
to DNSKEY records. This resulted in an incomplete key set. TTL
changes are now dealt with before signing. [RT #22590]
-
Corrected a defect where a combination of dynamic updates and zone
transfers incorrectly locked the in-memory zone database, causing
named to freeze. [RT #22614]
-
Don't run MX checks (check-mx) when the MX record points to ".".
[RT #22645]
-
DST key reference counts can now be incremented via dst_key_attach.
[RT #22672]
-
The IN6_IS_ADDR_LINKLOCAL and
IN6_IS_ADDR_SITELOCAL macros in win32 were updated/corrected
per current Windows OS. [RT #22724]
-
"dnssec-settime -S" no longer tests prepublication interval validity
when the interval is set to 0. [RT #22761]
-
isc_mutex_init_errcheck() in phtreads/mutex.c failed to destroy attr. [RT #22766]
-
The Kerberos realm was being truncated when being pulled from the
the host prinicipal, make krb5-self updates fail. [RT #22770]
-
Fixed GSS TSIG test problems for Solaris/MacOSX. [RT #22853]
-
Prior to this fix, when named was was writing a zone to disk (as slave,
when resigning, etc.), it might not correctly preserve the case of domain
name labels within RDATA, if the RDATA was not compressible. The result is
that when reloading the zone from disk would, named could serve data
that did not match the RRSIG for that data, due to case mismatch. named
now correctly preserves case. After upgrading to fixed code, the
operator should either resign the data (on the master) or delete the
disk file on the slave and reload the zone. [RT #22863]
-
The man page for dnssec-keyfromlabel incorrectly had "-U" rather
than the correct option "-I". [RT #22887]
-
The "rndc" command usage statement was missing the "-b" option.
[RT #22937]
-
Fixed a possible deadlock due to zone re-signing.
[RT #22964]
-
The TTL for DNS64 synthesized answers was not always set correctly.
[RT #23034]
-
The secure zone update feature in named is based on the zone
being signed and configured for dynamic updates. A bug in the ACL
processing for "allow-update { none; };" resulted in a zone that is
supposed to be static being treated as a dynamic zone. Thus, name
would try to sign/re-sign that zone erroneously. [RT #23120]
-
When using auto-dnssec and updating DNSKEY records, named did correctly
update the zone. [RT #23232]
-
After a failed zone transfer of an RPZ (response policy zone), named
would respond with SERVFAIL for subsequent queries in the RPZ zone.
[RT #23246]
-
If a slave initiates a TSIG signed AXFR from the master and the master
fails to correctly TSIG sign the final message, the slave would be left
with the zone in an unclean state. named detected this error too late
and named would crash with an INSIST. The order dependancy has been
fixed. [RT #23254]

With React 16.8, React Hooks are available in a stable release!
Hooks let you use state and other React features without writing a class. You can also build your own Hooks to share reusable stateful logic between components.
If you've never heard of Hooks before, you might find these resources interesting:
You don't have to learn Hooks right now. Hooks have no breaking changes, and we have no plans to remove classes from React. The Hooks FAQ describes the gradual adoption strategy.
We don't recommend rewriting your existing applications to use Hooks overnight. Instead, try using Hooks in some of the new components, and let us know what you think. Code using Hooks will work side by side with existing code using classes.
Yes! Starting with 16.8.0, React includes a stable implementation of React Hooks for:
Note that to enable Hooks, all React packages need to be 16.8.0 or higher. Hooks won't work if you forget to update, for example, React DOM.
React Native will support Hooks in the 0.59 release.
React Hooks are now supported by React DevTools. They are also supported in the latest Flow and TypeScript definitions for React. We strongly recommend enabling a new lint rule called eslint-plugin-react-hooks
to enforce best practices with Hooks. It will soon be included into Create React App by default.
We described our plan for the next months in the recently published React Roadmap.
Note that React Hooks don't cover all use cases for classes yet but they're very close. Currently, only
getSnapshotBeforeUpdate()
and componentDidCatch()
methods don't have equivalent Hooks
APIs, and these lifecycles are relatively uncommon. If you want, you should be able to use Hooks in most of the new
code you're writing.
Even while Hooks were in alpha, the React community created many interesting examples and recipes using Hooks for animations, forms, subscriptions, integrating with other libraries, and so on. We're excited about Hooks because they make code reuse easier, helping you write your components in a simpler way and make great user experiences. We can't wait to see what you'll create next!
We have added a new API called ReactTestUtils.act()
in this release. It ensures that the behavior in
your tests matches what happens in the browser more closely. We recommend to wrap any code rendering and triggering
updates to your components into act()
calls. Testing libraries can also wrap their APIs with it (for
example, react-testing-library
's render
and fireEvent
utilities do this).
For example, the counter example from this page can be tested like this:
import React from 'react';
import ReactDOM from 'react-dom';
import { act } from 'react-dom/test-utils';
import Counter from './Counter';
let container;
beforeEach(() => {
container = document.createElement('div');
document.body.appendChild(container);
});
afterEach(() => {
document.body.removeChild(container);
container = null;
});
it('can render and update a counter', () => {
// Test first render and effect
act(() => {
ReactDOM.render(<Counter />, container);
});
const button = container.querySelector('button');
const label = container.querySelector('p');
expect(label.textContent).toBe('You clicked 0 times');
expect(document.title).toBe('You clicked 0 times');
// Test second render and effect
act(() => {
button.dispatchEvent(new MouseEvent('click', {bubbles: true}));
});
expect(label.textContent).toBe('You clicked 1 times');
expect(document.title).toBe('You clicked 1 times');
});
The calls to act()
will also flush the effects inside of them.
If you need to test a custom Hook, you can do so by creating a component in your test, and using your Hook from it. Then you can test the component you wrote.
To reduce the boilerplate, we recommend using react-testing-library
which is designed to encourage writing tests that use your components as the end users do.
We'd like to thank everybody who commented on the Hooks RFC for sharing their feedback. We've read all of your comments and made some adjustments to the final API based on them.
React v16.8.0 is available on the npm registry.

To install React 16 with npm, run:
We also provide UMD builds of React via a CDN:

Note
As mentioned above, we strongly recommend using the
eslint-plugin-react-hooks
lint rule.If you're using Create React App, instead of manually configuring ESLint you can wait for the next version of
react-scripts
which will come out shortly and will include this rule.
Assuming you already have ESLint installed, run:

As with all our minor releases, none of the changes break backwards compatibility.
If you're currently using Hooks from an alpha build of React, note that this release does contain some small breaking changes to Hooks. We don't recommend depending on alphas in production code. We publish them so we can make changes in response to community feedback before the API is stable.

Functional programming is a programming paradigm where programs are constructed by composing pure functions, avoiding shared state, mutable data, and side effects. Many operators in functional programming are commonly used to make code more concise, and less complex.
This tutorial demonstrates the usage functional operator blocks: filter, map, reduce and sort.
Part 1: Berry’s Lemonade Stand
Berry is fundraising by setting up a lemonade stand, where she charges $2 per lemonade. As shown below, she keeps a simple record of the number of lemonades she sold on each date. She planned on doing this for seven consecutive days but was not able to set up her stand on some days, so for those days she wrote down N/A for the number of lemonades sold. Berry is interested in finding her total profit for this week’s lemonade stand.
Thus, Berry needs to
- keep only the entries that are numbers in her column of “# of Lemonades Sold” (filter),
- multiply each entry by $2 to get a list of daily profits (map), and then
- sum up all the daily profit entries to get total profit (reduce).
Step 1: Filter
Berry needs to return a new list that results from filtering her original list so that “N/A” entries are eliminated and only numbers exist in list.
The filter block takes in two inputs: 1) an input list and 2) a body block that is a boolean expression involving item–it returns true or false. Note that item is a variable name that refers to the current list item. The filter block iterates through the list and keeps each item the list that makes the body block return true. In this case, the input list is Berry’s original list, and the body block checks to see if item is a number.
Step 2: Map
Now that Berry has a filtered list of # of lemonades sold, she needs to multiply each item in the list by $2 to return a new list of daily profits.
The map block takes in two inputs: 1) an input list and 2) a body block that is an expression manipulating item. The map block iterates through the list and maps each item in the list to a new item using the body block. In this case, the input list is Berry’s filtered list, and the body block multiplies each item by 2.
Step 3: Reduce
Finally, Berry wants to sum up all the items in her list of daily profits to find her total profit.
The reduce block takes in three inputs: 1) an input list, 2) initialAnswer and 3) a body block that combines item (referring to the current list item) and answerSoFar (referring to the accumulating answer). If the input list is empty, then initialAnswer is returned. Otherwise, answerSoFar is initialized to initialAnswer. The body block is first evaluated using answerSoFar (which is equivalent to initialAnswer at this point) and the first list item, and then on the accumulating answer and the next list item, and so on until the end of the list.
In this case, the input list is Berry’s list of daily profits, the initialAnswer is 0, since the sum of all the items in an empty list is 0, and the body block adds the current list item to the accumulating answer to sum all her daily profits.
Berry decides to define her procedure as getTotalProfit. When getTotalProfit is called, Berry’s total profit from her lemonade stand is returned.
Part 2: Bob’s classmates’ height
Bob is collecting data about his classmates’ height. Here is a small part of his data:
BobDataList is a list of lists, as shown below:
Thus, Bob would like to have the list being sorted in following three different ways:
- Sort the data alphabetically by last name (basic sort)
- Sort the data alphabetically by gender, then numerically by height (sort with comparator)
- Sort the data alphabetically by height (sort with key)
Situation 1: Basic Sort
Bob wants to sort the list by last name.
Since last name is in index 1 of each item in BobDataList, he can simply input his list into the basic sort block.
Situation 2: Sort with Comparator
Bob wants to first sort his data alphabetically by gender, then numerically by height. In other words, the females are listed first, followed by males. Within females and within males, the data is organized by height. Gender is index 3 of each item in BobDataList, and height is in index 4 of each item in BobDataList.
In this case, Bob can use the sort with comparator block. This block takes in two inputs: 1) an input list and 2) a body block that specifies the order by which the the input list should be sorted. The body block is a boolean expression involving item1 and item2 and returns true or false. The given variable names, item1 and item2, refer to the two current list items that are being compared.
To achieve Bob’s goal, the body block will have two boolean expressions. The first boolean expression checks to see if the gender of item1 is less than the gender of item2. If is, then the body returns true immediately. If not (i.e. the gender is the same), then the second boolean expression will check to see if the height of item1 is less than the height of item2.
To implement this in terms of blocks, the body block will combine the two boolean expressions using an “or” block. An “or” block tests the conditions from left to right, and stops testing as soon as one of the conditions is true.
Situation 3: Sort with Key
Bob wants to sort his data only by height.
In this case, he can use the sort with key block. This sort block takes in two inputs: 1) an input list and 2) a body block (key) that is a function that is applied to each item in the list prior to sorting. The list of proxy values returned by the key is used for sorting.
Since Bob would like to sort by height, the body of the block gets index 4 of each item in BobDataList, and sorts by this value.
