The sub-window that you use to view or modify a formation is called a Formation Editor.
At right you can see a sample image of the 'diamond' formation loaded in a Formation Editor. Note that the text fields at top are greyed out to indicate that the editing of this definitions file is locked to prevent accidental editing.
The name can be any valid, single word (with underlines and dollar signs, but no digits). This name must match that used in the pattern strings used in call definitions.
If a formation is specific to rings, the Geometry field will say Ring. If blank, the formation applies in any geometry. See the Call Writer's Guide for more information about geometries to fully understand the setting of this field.
The bulk of the editor consists of a field of small crosses at regular intervals. As you resize the window, you'll notice that like the Animator, the spacing changes. Each cross represents a half-spot in an imaginary grid.
When you create a new formation, you will be given a completely empty field to work in. If you click on any of the crosses, it will turn into a green circle. Any colored circle represents a dancer.
In the 'diamond' formation here, the additional decorations and inscribed letters include more information about the specific dancer.
Formations are always rotated as needed to match dancers on the floor. There is no way to specify where the caller is standing. Even though formations are drawn like a full square in the Animator, the caller could be standing in any direction, and if the whole square is at an odd angle to the caller, the formation could match there as well.
Also, an empty spot in the formation editor can be either empty on the floor or occupied. Currently, there is no way to specify in a formation with fewer than 8 dancers that any particular spot must be empty. If there are more dancers than the formation indicates, those dancers could be anywhere on the floor.
If you right-click on an empty grid spot, you'll see this menu. Right-clicking on a dancer spot gives you basically the same menu, but with one additional option at the bottom "Make this spot empty" (and leaving out the option that would make the dancer be what they already are, for example omitting "Make this spot an active dancer" for a spot that it already an active dancer).
Currently, Inactive dancers are not used in any formations. While you can select this option, the formation matching code will not do anything useful.
If you select 'active dancer', you get an empty green circle just as you do by left-clicking on an empty spot. This could be any dancer on the floor.
By choosing Boy or Girl dancers in the formation, the color of the circle changes to the selected gender and you see a B or G, respectively, inside the circle. Such a spot in the formation would only match the corresponding gendered dancer. Look at the 'normal_couple' formation for an example of genedered formation spots.
Designated and non-designated dancers are used commonly in ANYONE calls when the designated dancers must be standing in a particular spot within the formation to match. If you selected either designated or non-designated active dancers for spots in the formation, all dancer spots should probably be one or the other. When you write a pattern as a formation name followed by an ANYONE phrase (usually a variable mentioned in the call definition's phrases), that pattern says to match the named formation using the designated dancers. Look at the definition of "ANYONE chain" for an example of such a pattern. When matching the pattern, the designated dancers must be standing on spots in the formation marked with a D and other active dancers must be standing on the non-designated spots (marked by an N).
Center, end, very center and very end dancer markings are used to indicate which positions in a formation can be designated using the corresponding phrases. All the currently active dancers must match the entire formation in order to be applied.
If you use a pattern that has center/end in a definition, the dancers do not have to be designated in any way by the call. For call matching, center/end markings are ignored and all dancers are merely considered 'active'. The center and end markings are only used to decide which dancers are designated by the corresponding phrases. There is currenlty no way to specify 'center 6/end 2' or related combinations.
If you use a pattern that has designated/non-designated dancers without a parenthesized ANYONE phrase, the formation is matched by treating all such dancers as merely 'active'.
The bumps on the circles in the formation editor indicate possible facing directions. If the circle has no bumps at all, the dancer could be facing in any direction. If two bumps appear, the dancer could be facing either direction that has a bump. If only one bump appears, the dancer can only face that direction.
You set the direction indicators after you first make a spot into a dancer spot. They will always start with any facing direction allowed. As you move your mouse over the dancer, you will notice that around the edges, the cursor changes to a cross shape. Clicking there will set the dancer to face that one specific direction. Clicking again will return the dancer to allow any facing.
If you move the cursor to the opposite side of the circle when there is already a single bump, the cursor will change into a appropriately directed double-arrow. Clicking there will change the dancer to allow either facing direction. Clicking again on the same spot will switch the dancer back to single-facing.
There is no way to specify that dancers could be facing any of three different directions. If you move the mouse cursor over one of the other sides of a two-faced dancer, the mouse cursor will change to a 'disallowed' circle with a bar through it symbol.
Note that the mouse cursor will also change to a 'disallowed' symbol when you move over an empty spot that it too close to an existing dancer spot. In general, dancers can never be only a half-spot apart, so you are not allowed to create a formation with dancers spaced that way. You must first remove some existing dancers before you can place a dancer on such a location.

Farmer John has exactly $5 to spend. He can buy 5 tools at $1 each or 1 tool at $3 and an additional 1 tool at $2. Of course, there are other combinations for a total of 5 different ways FJ can spend all his money on tools. Here they are:
1 @ US$3 + 1 @ US$2
1 @ US$3 + 2 @ US$1
1 @ US$2 + 3 @ US$1
2 @ US$2 + 1 @ US$1
5 @ US$1

I'd been depressed after a somewhat painful relationship thankfully ended. Anyway, a few months had passed and I still wasn't feeling any better. I was really sick. I'd suffered bouts of depression in the past and was just over it. I told my therapist to dose me. I'd done some research and had come to the conclusion that I did not want to take an SSRI, like Prozac, they kill woodies. No thanks. I really didn't know what to expect with the Wellbutrin.
I'd been told that it may take up to week for me to feel anything. That was clearly not the case with me. About a half an hour after taking 150mgs in the morning I could feel the stuff working, and how. It felt really good, I was focused and alert yet tranquil and very much in control of my emotions. It took the edge off for sure. I was able to get through my day with a smile instead of a scowl; a welcome change.
Side effects: The first two weeks I had lower intestinal cramps. Third week I had head aches. Both of those symptoms have since passed. My biggest problem with it now is fitful sleep with disturbingly vivid dreams. Sometimes it doesn't even feel like I'm sleeping, although I guess I am.
One more thing on the positive side is that it seems to have greatly enhanced my sex drive and seems to have hightend the pleasurable senstations of sex, even if it's just whacking off. This may be directly related to the drug itself, or it could also be because it pretty much got rid of my depression. Maybe a combintaion of the two, I'm not sure.

Organizing Data
- “Tidy Data” by Hadley Wickham.
- Don’t pay much attention to any R code you encounter, as most of it has now been superseded by newer tidyverse functions.
- This was Wickham’s early “tidy tools” manifesto; it provided guiding principles and a framework for developing the tidyverse.
- Don’t pay much attention to any R code you encounter, as most of it has now been superseded by newer tidyverse functions.
- Peruse the website “Data Organization in Spreadsheets”, much of which has been written up in a journal article:
Broman KW, Woo KH (2018) Data organization in spreadsheets. The American Statistician 78:2–10. PDF ( 3.9 MB)
Importing Data
- R4DS, Ch. 10: Tibbles (short)
- R4DS, Ch. 11.2: Data Import, “Getting started”
- I suggest working through the exercises to help you understand the code.
Supplemental Reading
Do you need to read messy files? I suggeset reading the remainder of R4DS, Ch. 11. In particular:
- Section 11.3, “Parsing a Vector” decribes a variety of functions provided by the
readr
package to analyze and interpret different kinds of input and figure out what kind of value it’s supposed to be. For example, understanding that the value represents a number when it’s formatted as$123,456,789
, or that the value represents a date when it’s formatted asoct. 14, 1979
or1 enero 2015
. - Section 11.4, “Parsing a file” describes strategies for guessing column types during import, diagnosing problems, and overriding the defaults when the guesses fail.


Fragment caching is used for caching various blocks within templates without caching the entire action as a whole. This is useful when certain elements of an action change frequently or depend on complicated state while other parts rarely change or can be shared amongst multiple parties. The caching is done using the cache helper available in the Action View. A template with caching might look something like:
<b>Hello <%= @name %></b> <% cache do %> All the topics in the system: <%= render :partial => "topic", :collection => Topic.find(:all) %> <% end %>
This cache will bind to the name of the action that called it, so if this code was part of the view for the topics/list action, you would be able to invalidate it using expire_fragment(:controller => "topics", :action => "list").
This default behavior is of limited use if you need to cache multiple fragments per action or if the action itself is cached using caches_action, so we also have the option to qualify the name of the cached fragment with something like:
<% cache(:action => "list", :action_suffix => "all_topics") do %>
That would result in a name such as "/topics/list/all_topics", avoiding conflicts with the action cache and with any fragments that use a different suffix. Note that the URL doesn‘t have to really exist or be callable - the url_for system is just used to generate unique cache names that we can refer to when we need to expire the cache.
The expiration call for this example is:
expire_fragment(:controller => "topics", :action => "list", :action_suffix => "all_topics")
Removes fragments from the cache.
key can take one of three forms:
- String - This would normally take the form of a path, like "pages/45/notes".
- Hash - Treated as an implicit call to url_for, like {:controller => "pages", :action => "notes", :id => 45}
- Regexp - Will remove any fragment that matches, so %r{pages/\d*/notes} might remove all notes. Make sure you don‘t use anchors in the regex (^ or $) because the actual filename matched looks like ./cache/filename/path.cache. Note: Regexp expiration is only supported on caches that can iterate over all keys (unlike memcached).
options is passed through to the cache store‘s delete method (or delete_matched, for Regexp keys.)

Given a key (as described in expire_fragment), returns a key suitable for use in reading, writing, or expiring a cached fragment. If the key is a hash, the generated key is the return value of url_for on that hash (without the protocol). All keys are prefixed with "views/" and uses ActiveSupport::Cache.expand_cache_key for the expansion.

The aim of this app is to perform geometrical calculations that might be useful in the workshop. It consists of six tabs for different shapes or type of calculation.
Fields with a grey background are not user-editable. As a general rule, only fields with a non-zero value are treated as inputs. Values can be entered to any precision but are calculated to 3 decimals.
Press the CALCULATE button to calculate the missing fields based on the supplied data. Press RESET to clear the fields on the current tab.
Circles Tab
This tab calculates aspects of circles, chords and segments.
Required fields: Any one of the first four fields, which refer to the circle, or both the chord length and depth, from which details of the circle can be calculated.
Optional fields: Any one of the second group of four fields, which refer to a segment of the circle.
Notes on fields:
- Segment height is the distance from the centre of the circle to the centre of the chord
- Chord depth is the distance from the perimeter to the centre of the chord
- Segment area is the area of the triangular part of the segment (centre to chord)
- Chord area is the area between the chord and the perimeter. The total segment area is the sum of these two
Polygons Tab
This section handles regular polygons such as triangles, squares, hexagons, etc.
Required fields: The number of sides (3 or more) and one other value.
Notes on fields:
- Internal angle is the angle between adjacent faces measured at the vertex
- Centre angle is the angle between vertices measured at the centre. This is also the external angle between the extension of one face and the adjacent face
- Inner radius & diameter refer to the inscribed circle that touches the centre of each face. For a shape with an even number of sides, such as a hexagon, the inner diameter is the distance across flats
- Outer radius & diameter refer to the superscribed circle that touches each vertex
- Height is the overall height when one face is horizontal. For an even-numbered polygon it is the same as the inner diameter
Right Triangles Tab
This section deals with triangles containing a right angle. Equilateral triangles are handled by the Polygons section. Scalene triangles are generally the sum or difference of two right triangles and do not have a separate section.
Required fields: Any two fields
Notes on fields:
- The first side is on the opposite side of the triangle to the first angle; likewise with the second side and angle
Rectangles Tab
This section deals with simple rectangles or squares. Squares are also handled by the Polygons section.
Required fields: Any two fields
PCD Tab
This section deals with pitch circle diameters, including the size of the holes.
Required fields: PCD and count or angle
Optional fields: hole size, coordinate reference
Notes on fields:
- Across centres is the distance from one hole centre to the next, as would be set on compasses for marking out
- Across holes is the distance from the edge of one hole to the opposite edge of the next as would be measured when checking
Selecting 'Centre' or 'Corner' makes the app calculate the coordinates of the holes with reference to the specified point:
- Centre - the X and Y distances are from the centre of the PCD circle with the first hole directly above and the angle incrementing clockwise. Negative distances are below or to the left of the centre
- Corner - the X and Y distances are from the top, left corner of the square containing the PCD circle. The first hole is in the middle of the top edge. Angles increment clockwise and are from the centre (not the corner)
Sine Tab
This section is a simplification of the Right Triangles section specifically for sine bars. The height and length do not need to be real lenghts but could be chosen to specify a gradient, such as 1 in 100, etc.
Required fields: Any two fields
Lengths tab
This section converts between millimeters and inches. Inches are entered or displayed in both decimal and fractional form.
Notes on fields:
- Convert millimeters to inches - enter the length in mm. The app calculates the decimal inch equivalent and the nearest fraction (up to 64ths). If the fraction is too low, a positive error is calculated. If it is too high the error is negative. For example, 4mm converts to 0.1575" and is 1.2 thou over 5/32".
- Convert inches to millimeters - enter the decimal inches. The app calculates the equivalent number of millimeters and the fractional inches as above. For example, 1.2" equates to 30.48mm and is 3.1 thou under 1.13/64".
- Convert fractional inches to millimeters - enter whole numbers in all three fields. The app calculates millimeters and decimal inches.

Thanks for this PR.
When the format for Sapling incoming viewing keys (section 5.6.6 of the protocol spec) was defined, I overlooked that there would not be sufficient information to tell which address it was meant for. We'll need to consider whether the external format should change in order to include that information, before merging this PR or equivalent.

In case my previous post left readers in doubt about whether or not I like Functional Programming (FP), this post should make it clear that I (also) love FP.
A couple of years ago I had the pleasure of performing a technical review of Real World Functional Programming, which caused me to significantly shift my C# coding style towards a more functional style.
Now I want to take the next step, so I've started doing katas in F#. In a series of blog posts, I'll share my experiences with learning F# as I go along. I'm sure that the F# gods will wince from my code, but that's OK - if any of my readers find this educational, my goal will be met.
In this post I'll start out with the first use case of the Bank OCR kata.
The first thing I wanted to do was write a couple of tests to demonstrate that I could parse the input.
In the test function body itself, I pipe the entry function argument into the ParseToNumber function using the pipeline operator |>, so
entry |> ParseToNumber
is equivalent to writing
ParseToNumber entry
However, by piping the input into the SUT and the result further on to the assertion, I achieve a very dense test method where it's fairly clear that it follows the Arrange Act Assert (AAA) pattern.
The assertion is expressed using FsUnit's F# adapter over xUnit.net. It should be clear that it states that the result (piped from the ParseToNumber function) should be equal to the expected function argument.
Here's the body of the ParseToNumber function:
let ParseToNumber entry = entry |> ParseToDigits |> Seq.map Option.get |> Seq.reduce (fun x y -> x * 10 + y)
If you're used to read and write C# you may be wondering about the compactness of it all. Where are all the type declarations?
F# is a strongly typed language, but it has very sophisticated type inferencing capabilities, so the compiler is able to infer that the signature is string - > int, which (in this case) is read as a function which takes a string as input and returns an integer. The equivalent C# notation would be public int ParseToNumber(string entry).
How does the F# compiler know this?
The entry parameter is easy to infer because the function body invokes the ParseToDigits function, which takes a string as input. Therefore, entry must be a string as well.
The output type is a little harder to understand, but basically it boils down to something like this: the ParseToDigits function returns a sequence (basically, an IEnumerable<T>) of integer options. The Seq.map function converts this to a sequence of integers, and the Seq.fold function aggregates that sequence into a single integer.
Don't worry if you didn't understand all that yet - I'll walk you through the body of the function now.
The entry argument is piped into the ParseToDigits function, which returns a sequence of integer options. An option is a type that either has, or doesn't have, a value, so the next step is to unwrap all the values. This is done by piping the option sequence into the Seq.map function, which is equivalent to the LINQ Select method. The Option.get method simply unwraps a single option. It will throw an exception if the value is None, but in this implementation, this is the desired behavior.
The last thing to do is to aggregate the sequence of integers into a single number. The Seq.reduce method aggregates the sequence according to a given accumulator function.
In F#, an inline code block is written with the fun keyword, but it's entirely equivalent to a C# code block, which would look like this:
(x, y) => x * 10 + y
This function basically interprets the sequence of integers as a stream of digits, so in order to arrive at the correct digital representation of the number, each accumulated result is multiplied by ten and added to the new digit.
Obviously, all the real parsing takes place in the ParseToDigits function:
let ParseToDigits (entry : string) = let toIntOption ocrDigit = match ocrDigit |> Seq.toArray with | [| (' ', '|', '|'); ('_', ' ', '_'); (' ', '|', '|') |] -> Some 0 | [| (' ', ' ', ' '); (' ', ' ', ' '); (' ', '|', '|') |] -> Some 1 | [| (' ', ' ', '|'); ('_', '_', '_'); (' ', '|', ' ') |] -> Some 2 | [| (' ', ' ', ' '); ('_', '_', '_'); (' ', '|', '|') |] -> Some 3 | [| (' ', '|', ' '); (' ', '_', ' '); (' ', '|', '|') |] -> Some 4 | [| (' ', '|', ' '); ('_', '_', '_'); (' ', ' ', '|') |] -> Some 5 | [| (' ', '|', '|'); ('_', '_', '_'); (' ', ' ', '|') |] -> Some 6 | [| (' ', ' ', ' '); ('_', ' ', ' '); (' ', '|', '|') |] -> Some 7 | [| (' ', '|', '|'); ('_', '_', '_'); (' ', '|', '|') |] -> Some 8 | [| (' ', '|', ' '); ('_', '_', '_'); (' ', '|', '|') |] -> Some 9 | _ -> None let lines = entry.Split([| "\r\n" |], StringSplitOptions.RemoveEmptyEntries) Seq.zip3 lines.[0] lines.[1] lines.[2] |> chunk 3 |> Seq.map toIntOption
That may look scary, but is actually not that bad.
The function contains the nested function toIntOption which is local to the scope of ParseToDigits. One of the things I don't like that much about F# is that you have to declare and implement the details before the general flow, so you almost have to read the code backwards if you want the overview before diving into all the details.
The first thing the ParseToDigit function does is to split the input into three lines according to the specification of the kata. It uses the standard .NET String.Split method to do that.
Next, it zips each of these three lines with each other. When you zip something, you take the first element of each sequence and create a tuple out of those three elements; then the second element of each sequence, and so forth. The result is a sequence of tuples, where each tuple represents a vertical slice down a digit.
As an example, let's look at the digit 0:
_ | | |_|
The first vertical slice contains the characters ' ', '|' and '|' so that results in the tuple (' ', '|', '|'). The next vertical slice corresponds to the tuple ('_', ' ', '_') and the third (' ', '|', '|').
With me so far? OK, good.
The Seq.zip3 function produces a sequence of such tuples, but since the kata states that each digit is exactly three characters wide, it's necessary to divide that stream of tuples into chunks of three. In order to do that, I pipe the zipped sequence to the chunk function.
Seq.zip3 lines.[0] lines.[1] lines.[2] |> chunk 3
I'll post the chunk function further down, but the result is a sequence of sequence of chars which can then be mapped with the toIntOption function.
Now that I've explained how those tuples look, the toIntOption shouldn't be too hard to understand. Each ocrDigit argument is expected to be a sequence of three tuples, so after creating an array from the sequence, the function uses pattern matching to match each tuple array to an option value.
It simply matches an array of the tuples (' ', '|', '|'); ('_', ' ', '_'); (' ', '|', '|') to the number 0 (as explained above), and so on.
If there's no match, it returns the option value None, instead of Some.
Hang on, I'm almost done. The last part of the puzzle is the chunk function:
let rec chunk size sequence = let skipOrEmpty size s = if s |> Seq.truncate size |> Seq.length >= size then s |> Seq.skip size else Seq.empty seq { yield sequence |> Seq.truncate size let next = sequence |> skipOrEmpty size if not (Seq.isEmpty next) then yield! chunk size next }
Just like the ParseToDigits function, the chunk function uses a nested function to do some of its work.
First of all you may notice that the function declaration uses the rec keyword, which means that this is a recursive function. FP is all about recursion, so this is just something you'll have to get used to.
The main part of the function consists of a sequence expression, denoted by the seq keyword.
First the function returns the first n elements from the sequence, in order to return the first chunk. Next, it skips that chuck and if the sequence isn't empty it recursively calls itself with the rest of the sequence.
The skipOrEmpty function is just a little helper function to work around the behavior of the Seq.skip function, which throws an exception if you ask it to skip some elements of a sequence which doesn't contain that many elements.
That's it. The code is actually quite compact, but I just took a long time explaining it all in some detail.
In a future post I'll walk through the other use cases of the Bank OCR kata.
Comments
Yeah, in a small example like this it doesn't really matter and readability is more important. But I think things like this should be mentioned, so that people are not surprised if they try to use the function in different contexts.


I am an overly passionate person when it comes to developing my knowledge in Computer Science. Grounded yet enthusiastic, I want to give some of my creativity to the world.
My life long dream is to develop video games that are impactful in their immersiveness. Developing a full-dive virtual reality game is within the scopes of my ambition and I aim to do whatever it takes to make it a reality.
After discovering my passion for Computer Science, I did everything in my ability to contribute to developing it further!
My knowledge on Java has grown as a result of being my school robotic's team programmer.
I've acquired knowledge in HTML, the most fundamental language of web design, to build website infrastructure.
Naturally, in order to make my websites look nice, I have used CSS to make them look nice.
I've used JavaScript to make animations, add features, and make my websites run smoother.
I want to become the best I can be in terms of programming. I am in the process of acquiring the acquisition of new languages.
Used in game development, C++ is an essential language to any developer. I plan on developing my knowledge C++ further.
Along with C++, C# is also involved in making games. Unity, a game engine, uses C# as its primary language.
Python is a programming language that can be used for multiple purposes. It is an ever-growing language that I plan to get to know.
PHP provides functions to website. Learning PHP would drastically strengthen my ability to make websites.

Here are the top 5 reasons why you should start your own podcast:
Audio content is convenient for the consumer
I think it was Seth Godin who said that as marketers, what we are competing for most is someone’s attention.
There is an overwhelming amount of information available to all of us, coupled with so many distractions,
that focusing 100% of our attention on one specific piece of content (an article or a video for example) is
becoming increasingly difficult to do.
It’s difficult to ignore everything else that
wants your attention to focus 100% of your attention on reading an article or watching a video in its entirety.
The great thing about a podcast is that your content is audio, and can be consumed while the listener is
also doing something else. They can multi-task. Someone can listen to your podcast while cleaning their
house, driving in their car, jogging, or exercising at the gym. Doing so doesn’t distract them from their
current activity, it enriches it. Audio content is portable and convenient.
To build an audience
Just like with a blog, a podcast is a way for you to build an audience. As your podcast grows in popularity,
the size of your audience increases. Not everyone who listens to your show will come back for more, but the
ones who like your style and your content will become loyal listeners. They will recommend your show to others,
and over time you will build a tribe of fans eager to hear your next episode.
Hosting your show on platforms such as iTunes or Stitcher will also expose your show to new listeners who find
your show by searching for specific topics on those platforms. For example, if you host a show about cooking,
someone looking for a podcast about cooking will find your show if it appears in the search results for that keyword.
It doesn’t cost much to get started
If you wanted to start podcast 10 years ago, you would have likely had to spend several thousand dollars on equipment
just to get started. Fortunately, this is no longer the case. When I launched my podcast in 2013, I spent about $250
on equipment. And since then the cost for the same equipment has come down by nearly 50%.
There are only a few pieces of equipment required to host your show. The first is of course a computer (or laptop)
with an internet connection.
I currently use a Blue Yeti microphone, a pair of Sony headphones, and a pop filter. I recently found a similar
combination (different headphones) of equipment on Amazon for $139.99. Very good deal.
To increase the size and value of your network
If you host a podcast in which you interview various guests for your show, one of the most obvious benefit of doing
so is that you get to expand your network. A podcast is a great platform to leverage to reach out to people you might
not have been able to otherwise. As your audience grows in size, your ability to reach out to the high profile
experts in your industry increases.
 As I write
this article, I’ve interviewed over 70 guests for my podcast, and I’ve kept in touch with nearly all of them. Some
of them have become very close friends, and in many cases we have worked together on certain projects or simply
shared ideas to help each other succeed.
You can make money from your show
A podcast doesn’t have to be a hobby. There are ways you can make money from your show. John Lee Dumas
(host of Entrepreneur On Fire) is an expert at this. His generates multiple 5 figures per month from sponsors
alone, and has taught thousands of people how to monetize their podcast. You are welcome to listen to the
interview I did with John by clicking here.
There are a few ways you can monetize your podcast. If your download numbers are high enough, you can charge
sponsors to be mentioned on your show. You can also use your show to promote your own products or services
(books, courses, or consulting, for example). Another option is to include a recommended resources section
on your show’s main website, and include affiliate links in each of the recommendations. This way, when
someone clicks on a recommended resources and decides to buy, your earn a commission from the sale.


Twenty Five Kent is a creative hub in construction on the waterfront of Williamsburg, Brooklyn. Expected to open in 2018, the building will be the first major office space in the neighborhood. Madwell created an identity for Twenty Five Kent that was built off of the area’s unique community. We teamed up with illustrator Christopher DeLorenzo to produce a family of characters that represent the variety of personalities found within the neighborhood.
We created a fully responsive website with an interactive blueprint, 360° renderings, and b-reel from a drone.

Hello, I hope this is the correct place to ask this. I was looking at the Theorem Proving in Lean book exercises in Chap 2 which asks to both add two vectors together and reverse a vector. I have the following questions:
1. Why does it want to make a constant instead of a definition?
2. Normally, I would pattern match in Haskell on the head and tail of a list to solve both problems, but I don't know how to do this without recursion (as recursion isn't mentioned until later in chap 8). Any hints as to how to do this without recursion would be appreciated.
Normally we would define that as a function, but this is early in the book and the question is only about getting the type right. For the exercise you aren't even trying to make the definition itself, just the type of the hypothetical definition
