Recently, Nat Pryce tweeted:
The diamond kata, TDD'd only with property-based tests. https://github.com/npryce/property-driven-diamond-kata One commit for each step: add test/make test pass/refactorThis made me curious. First, I'd never heard about the Diamond kata, and second, I find Property-Based Testing quite interesting these days.
Digging a bit lead me to a blog post by Seb Rose; the Diamond kata is extremely easy to explain:
After having thought about it a little, I couldn't even begin to see how one could approach this problem using Property-Based Testing. It struck me as a problem inherently suited for Example-Driven Development, so I decided to do that first.Given a letter, print a diamond starting with ‘A’ with the supplied letter at the widest point.
For example: print-diamond ‘C’ prints
A B B C C B B A
The no-brain approach to Example-Driven Development is to start with 'A', then 'B', and so on. Exactly as Seb Rose predicts, when you approach the problem like this, when you reach 'C', it no longer seems reasonable to hard-code the responses, but then the entire complexity of the problem hits you all at once. It's quite hard to do incremental development by going through the 'A', 'B', 'C' progression.
This annoyed me, but I was curious about the implementation, so I spent an hours or so toying with making the 'C' case pass. After this, on the other hand, I had an implementation that works for all letters A-Z.
On my commute it subsequently struck me that solving the Diamond kata with Example-Driven Development taught me a lot about the problem itsef, and I could easily come up with the first 10 properties about it.
Therefore, I decided to give the kata another try, this time with FsCheck. I also wanted to see if it would be possible to make the development more incremental; while I didn't follow the Transformation Priority Premise (TPP) to the letter, I was inspired by it. My third 'rule' was to use Devil's Advocate to force me to write properties that completely describe the problem.
To get started, it can be a good idea to write a simple (ice breaker) test, because there's always a little work involved in getting everything up and running. To meet that goal, I wrote this almost useless property:
[<Property(QuietOnSuccess = true)>] let ``Diamond is non-empty`` (letter : char) = let actual = Diamond.make letter not (String.IsNullOrWhiteSpace actual)
It only states that the string returned from the Diamond.make function isn't an empty string. Using Devil's Advocate, I created this implementation:
let make letter = "Devil's advocate."
This hard-coded result satisfies the single property. However, the only reason it works is because it ignores the input.
The kata only states what should happen for the inputs A-Z, but as currently written, FsCheck will serve all sorts of char values, including white space and funny characters like '<', ']', '?', etc. While I could write a run-time check in the make function, and return None
upon invalid input, I am, after all, only doing a kata, so I'd rather want to tell FsCheck to give me only the letters A-Z. Here's one way to do that:
type Letters = static member Char() = Arb.Default.Char() |> Arb.filter (fun c -> 'A' <= c && c <= 'Z') type DiamondPropertyAttribute() = inherit PropertyAttribute( Arbitrary = [| typeof<Letters> |], QuietOnSuccess = true) [<DiamondProperty>] let ``Diamond is non-empty`` (letter : char) = let actual = Diamond.make letter not (String.IsNullOrWhiteSpace actual)
The Letters type redefines how char values are generated, using the default generator of char, but then filtering the values so that they only fall in the range [A-Z].
To save myself from a bit of typing, I also defined the custom DiamondPropertyAttribute that uses the Letters type, and used it to adorn the test function instead of FsCheck's built-in PropertyAttribute.
Considering the TPP, I wondered which property I should write next, since I wanted to define a property that would force me to change my current implementation in the right direction, but only by a small step.
A good candidate seemed to state something about the top and bottom of the diamond: the first and the last line of the diamond must always contain a single 'A'. Here's how I expressed that in code:
let split (x : string) = x.Split([| Environment.NewLine |], StringSplitOptions.None) let trim (x : string) = x.Trim() [<DiamondProperty>] let ``First row contains A`` (letter : char) = let actual = Diamond.make letter let rows = split actual rows |> Seq.head |> trim = "A" [<DiamondProperty>] let ``Last row contains A`` (letter : char) = let actual = Diamond.make letter let rows = split actual rows |> Seq.last |> trim = "A"
Notice that I wrote the test-specific helper functions split
and trim
in order to make the code a bit more readable, and that I also decided to define the property for the top of the diamond separately from the property for the bottom.
In the degenerate case where the input is 'A', the first and the last rows are identical, but the properties still hold.
Using the Devil's Advocate, this implementation passes all properties defined so far:
let make letter = " A "
This is slightly better, but I purposely placed the 'A' slightly off-centre. In fact, the entire hard-coded string is 16 characters wide, so it can never have a single, centred letter. The next property should address this problem.
A fairly important property of the diamond is that it must be symmetric. Here's how I defined symmetry over the vertical axis:
let leadingSpaces (x : string) = let indexOfNonSpace = x.IndexOfAny [| 'A' .. 'Z' |] x.Substring(0, indexOfNonSpace) let trailingSpaces (x : string) = let lastIndexOfNonSpace = x.LastIndexOfAny [| 'A' .. 'Z' |] x.Substring(lastIndexOfNonSpace + 1) [<DiamondProperty>] let ``All rows must have a symmetric contour`` (letter : char) = let actual = Diamond.make letter let rows = split actual rows |> Array.forall (fun r -> (leadingSpaces r) = (trailingSpaces r))
Using the two new helper functions, this property states that the diamond should have a symmetric contour; that is, that it's external shape should be symmetric. The property doesn't define what's inside of the diamond.
Again, using the Devil's Advocate technique, this implementations passes all tests:
let make letter = " A "
At least the string is now symmetric, but it feels like we aren't getting anywhere, so it's time to define a property that will force me to use the input letter.
When considering the shape of the required diamond, we know that the first line should contain an 'A', the next line should contain a 'B', the third line a 'C', and so on, until the input letter is reached, after which the order is reversed. Here's my way of stating that:
[<DiamondProperty>] let ``Rows must contain the correct letters, in the correct order`` (letter : char) = let actual = Diamond.make letter let letters = ['A' .. letter] let expectedLetters = letters @ (letters |> List.rev |> List.tail) |> List.toArray let rows = split actual expectedLetters = (rows |> Array.map trim |> Array.map Seq.head)
The expression let letters = ['A' .. letter]
produces a list of letters up to, and including, the input letter. As an example, if letter
is 'D', then letters
will be ['A'; 'B'; 'C'; 'D']
. That's only the top and middle parts of the diamond, but we can use letters
again: we just have to reverse it (['D'; 'C'; 'B'; 'A']
) and throw away the first element ('D') in order to remove the duplicate in the middle.
This property is still quite loosely stated, because it only states that each row's first non-white space character should be the expected letter, but it doesn't say anything about subsequent letters. The reason I defined this property so loosely was that I didn't want to force too many changes on the implementation at once. The simplest implementation I could think of was this:
let make letter = let letters = ['A' .. letter] let letters = letters @ (letters |> List.rev |> List.tail) letters |> List.map string |> List.reduce (fun x y -> sprintf "%s%s%s" x System.Environment.NewLine y)
It duplicates the test code a bit, because it reuse the algorithm that generates the desired sequence of letters. However, I'm not too concerned about the occasional DRY violation.
For the input 'D', this implementation produces this output:
A B C D C B A
All properties still hold. Obviously this isn't correct yet, but I was happy that I was able to define a property that led me down a path where I could take a small, controlled step towards a more correct solution.
While I already have various properties that examine the white space around the letters, I've now temporarily arrived at an implementation entirely without white space. This made me consider how I could take advantage of those, and combine them with a new property, to re-introduce the second dimension to the figure.
It's fairly clear that the figure must be as wide as it's high, if we count both width and height in number of letters. This property is easy to define:
[<DiamondProperty>] let ``Diamond is as wide as it's high`` (letter : char) = let actual = Diamond.make letter let rows = split actual let expected = rows.Length rows |> Array.forall (fun x -> x.Length = expected)
It simply verifies that each row has exactly the same number of letters as there are rows in the figure. My implementation then became this:
let make letter = let makeLine width letter = match letter with | 'A' -> let padding = String(' ', (width - 1) / 2) sprintf "%s%c%s" padding letter padding | _ -> String(letter, width) let letters = ['A' .. letter] let letters = letters @ (letters |> List.rev |> List.tail) let width = letters.Length letters |> List.map (makeLine width) |> List.reduce (fun x y -> sprintf "%s%s%s" x Environment.NewLine y)
This prompted me to introduce a private makeLine function, which produces the line for a single letter. It has a special case to handle the 'A', since this value is the only value where there's only a single letter on a line. For all other letters, there will be two letters - eventually with spaces between them.
This seemed a reasonable rationale for introducing a branch in the code, but after having completed the kata, I can see that Nat Pryce has a more elegant solution.
If the input is 'D' the output now looks like this:
A BBBBBBB CCCCCCC DDDDDDD CCCCCCC BBBBBBB A
There's still not much white space in the implementation, but at least we regained the second dimension of the figure.
The next incremental change I wanted to introduce was the space between two letters. It seemed reasonable that this would be a small step for the makeLine function.
[<DiamondProperty>] let ``All rows except top and bottom have two identical letters`` (letter : char) = let actual = Diamond.make letter let isTwoIdenticalLetters x = let hasIdenticalLetters = x |> Seq.distinct |> Seq.length = 1 let hasTwoLetters = x |> Seq.length = 2 hasIdenticalLetters && hasTwoLetters let rows = split actual rows |> Array.filter (fun x -> not (x.Contains("A"))) |> Array.map (fun x -> x.Replace(" ", "")) |> Array.forall isTwoIdenticalLetters
The property itself simply states that each row must consist of exactly two identical letters, and then white space to fill out the shape. The way to verify this is to first replace all spaces with the empty string, and then examine the remaining string. Each remaining string must contain exactly two letters, so its length must be 2, and if you perform a distinct
operation on its constituent char values, the resulting sequence of chars should have a length of 1.
This property only applies to the 'internal' rows, but not the top and bottom rows that contain a single 'A', so these rows are filtered out.
The new property itself only states that apart from the 'A' rows, each row must have exactly two identical letters. Because the tests for the 'A' rows, together with the tests for symmetric contours, already imply that each row must have a width of an uneven number, and again because of the symmetric contour requirement, I had to introduce at least a single space between the two characters.
let make letter = let makeLine width letter = match letter with | 'A' -> let padding = String(' ', (width - 1) / 2) sprintf "%s%c%s" padding letter padding | _ -> let innerSpace = String(' ', width - 2) sprintf "%c%s%c" letter innerSpace letter let letters = ['A' .. letter] let letters = letters @ (letters |> List.rev |> List.tail) let width = letters.Length letters |> List.map (makeLine width) |> List.reduce (fun x y -> sprintf "%s%s%s" x Environment.NewLine y)
Using the Devil's Advocate technique, it seems that the simplest way of passing all tests is to fill out the inner space completely. Here's an example of calling Diamond.make 'D' with the current implementation:
A B B C C D D C C B B A
Again, I like how this new property enabled me to do an incremental change to the implementation. Visually, we can see that the figure looks 'more correct' than it previously did.
At this point I thought that it was appropriate to begin to address the diamond shape of the figure. After having spent some time considering how to express that without repeating the implementation code, I decided that the easiest step would be to verify that the lower left space forms a triangle.
[<DiamondProperty>] let ``Lower left space is a triangle`` (letter : char) = let actual = Diamond.make letter let rows = split actual let lowerLeftSpace = rows |> Seq.skipWhile (fun x -> not (x.Contains(string letter))) |> Seq.map leadingSpaces let spaceCounts = lowerLeftSpace |> Seq.map (fun x -> x.Length) let expected = Seq.initInfinite id spaceCounts |> Seq.zip expected |> Seq.forall (fun (x, y) -> x = y)
This one is a bit tricky. It examines the shape of the lower left white space. Getting that shape itself is easy enough, using the previously defined leadingSpaces helper function. For each row, spaceCounts
contains the number of leading spaces.
The expected
value contains an infinite sequence of numbers, {0; 1; 2; 3; 4; ...} because, due to the random nature of Property-Based Testing, I don't know exactly how many numbers to expect.
Zipping an infinite sequence with a finite sequence matches elements in each sequence, until the shortest sequence (that would be the finite sequence) ends. Each resulting element is a tuple, and if the lower left space forms a triangle, the sequence of tuples should look like this: {(0, 0); (1, 1); (2, 2); ...}. The final step in the property is therefore to verify that all of those tuples have identical elements.
The implementation uses Devil's Advocate, and goes quite a bit out of its way to make the top of the figure wrong. As you'll see shortly, it will actually be a simpler implementation to keep the figure symmetric around the horizontal axis as well, but we should have that as an explicit property.
let make letter = let makeLine width (letter, letterIndex) = match letter with | 'A' -> let padding = String(' ', (width - 1) / 2) sprintf "%s%c%s" padding letter padding | _ -> let innerSpaceWidth = letterIndex * 2 - 1 let padding = String(' ', (width - 2 - innerSpaceWidth) / 2) let innerSpace = String(' ', innerSpaceWidth) sprintf "%s%c%s%c%s" padding letter innerSpace letter padding let indexedLetters = ['A' .. letter] |> Seq.mapi (fun i l -> l, i) |> Seq.toList let indexedLetters = ( indexedLetters |> List.map (fun (l, _) -> l, 1) |> List.rev |> List.tail |> List.rev) @ (indexedLetters |> List.rev) let width = indexedLetters.Length indexedLetters |> List.map (makeLine width) |> List.reduce (fun x y -> sprintf "%s%s%s" x Environment.NewLine y)
The main change here is that now each letter is being indexed, but then I deliberately throw away the indexes for the top part, in order to force myself to add yet another property later. While I could have skipped this step, and gone straight for the correct solution at this point, I was, after all, doing a kata, so I also wanted to write one last property.
The current implementation produces the figure below when Diamond.make is called with 'D':
A B B C C D D C C B B A
The shape is almost there, but obviously, the top is wrong, because I deliberately made it so.
Just as the figure must be symmetric over its vertical axis, it must also be symmetric over its horizontal axis:
[<DiamondProperty>] let ``Figure is symmetric around the horizontal axis`` (letter : char) = let actual = Diamond.make letter let rows = split actual let topRows = rows |> Seq.takeWhile (fun x -> not (x.Contains(string letter))) |> Seq.toList let bottomRows = rows |> Seq.skipWhile (fun x -> not (x.Contains(string letter))) |> Seq.skip 1 |> Seq.toList |> List.rev topRows = bottomRows
This property finally 'allows' me to simplify my implementation:
let make letter = let makeLine width (letter, letterIndex) = match letter with | 'A' -> let padding = String(' ', (width - 1) / 2) sprintf "%s%c%s" padding letter padding | _ -> let innerSpaceWidth = letterIndex * 2 - 1 let padding = String(' ', (width - 2 - innerSpaceWidth) / 2) let innerSpace = String(' ', innerSpaceWidth) sprintf "%s%c%s%c%s" padding letter innerSpace letter padding let indexedLetters = ['A' .. letter] |> Seq.mapi (fun i l -> l, i) |> Seq.toList let indexedLetters = indexedLetters @ (indexedLetters |> List.rev |> List.tail) let width = indexedLetters.Length indexedLetters |> List.map (makeLine width) |> List.reduce (fun x y -> sprintf "%s%s%s" x Environment.NewLine y)
Calling Diamond.make with 'D' now produces:
A B B C C D D C C B B A
It works with other letters, too.
It turned out to be an interesting exercise to do this kata with Property-Based Testing. To me, the most surprising part was that it was much easier to approach the problem in an incremental fashion than it was with Example-Driven Development.

Loss of medial temporal lobe structures, particularly loss of the hippocampus, destroys the ability to convert new short-term memory to new long-term memory. -There is explicit and implicit memory (implicit is a collection of processes) -Milner showed that at least one type of memory can be traced to specific places in the brain -Early Eric Kandel -Gets lucky start recording in hippocampus -Decides to start recording in Aplysia – large and has only 20,000 neurons separated into nine ganglia (human brain ~ 100 billion) -Hypothesizes that persistent changes in the strength of synaptic connections results in memory storage -just as neurons and their synaptic connections are exact and invariant, so, too, the function of those connections is invariant. -First, we found that the changes in synaptic strength that underlie the learning of a behavior may be great enough to reconfigure a neural network and its information-processing ability -a given set of synaptic connections between two neurons can be modified in opposite ways— strengthened or weakened—by different forms of learning. -Third, the duration of short-term memory storage depends on the length of time a synapse is weakened or strengthened. -Fourth, we were beginning to understand that the strength of a given chemical synapse can be modified in two ways, depending on which of two neural circuits is activated by learning—a mediating circuit or a modulatory circuit -Learning may be a matter of combining various elementary forms of synaptic plasticity into new and more complex forms, much as we use an alphabet to form words. -forgetting had at least two phases: a rapid initial decline that was sharpest in the first hour after learning and then a much more gradual decline that continued for about a month. -Homosynaptic - the depression occurred in the same neural pathway that was stimulated -Strengthening synapses = greater responses -Short-term to Long-term -Memory consolidation – short-term is subject to disruption -Head injuries or seizures can lead to retrograde amnesia – you forget what was in you short-term memory -Electric shocks were able to get rid of short-term memory -A short-term memory lasting minutes is converted—by a process of consolidation that requires the synthesis of new protein—into stable, long-term memory lasting days, weeks, or even longer -Long-term memory results in growing or shedding synapses -As the memory fades, the number of synapses goes almost back to normal, with the difference accounting for relearning a task easier -Recall -Based on cues, in the case of Aplysia gill-withdrawal, external stimulus -Short-term -Short-term memory changes are presynaptic - during short-term habituation lasting minutes, the sensory neuron releases less neurotransmitter, and during short-term sensitization it releases more neurotransmitter -Relies on interneurons: -Mediating circuits – produce behavior directly, sensory neurons that innervate the siphon, the interneurons, and the motor neurons that control the gill-withdrawal reflex -Modulatory circuits - not directly involved in producing a behavior but instead fine-tunes the behavior in response to learning by modulating—heterosynaptically—the strength of synaptic connections between the sensory and motor neurons -For example, in gill-withdrawal sensitization, interneurons release serotonin into the presynaptic terminals of the sensory neurons -This generates a long, slow synaptic potential in the motor neurons -Ionotropic receptors – neurotransmitter-gated, open ion channels -Metabotropic receptors – gated, activate enzymes; these enzymes can make cyclic AMP, act much longer -Serotonin binds to metabotropic receptors in the presynaptic terminal of sensory neurons increasing the amount of cAMP and in turn the amount of glutamate -This was verified in studies of Drosophila -Sensory regions map to specific places in brain, keeping proximity -Pavlov -Habituation – animal repeatedly presented with neutral sensory stimulus learns to ignore it -Sensitization – animal learns strong stimulus is dangerous and enhances its defensive reflexes -Classical Conditioning – pair neutral stimulus with potentially dangerous stimulus, animal learns to respond to neutral stimulus -Long-term memory -Proteins must be made - DNA makes RNA, and RNA makes protein -The serotonin itself was able to make new synapses grow via synthesis of proteins in the nucleus -Genes -There are effector genes which mediate cellular functions and regulatory genes which switch them on and off -Genes have regions called promoters and repressors and regulatory proteins must bind to these in order to express them -With repeated pulses of serotonin, kinase A move into the nucleus – turn on regulatory protein called CREB which turns on some genes -Also requires turning off other genes -MAP kinase also moves into nucleus and depresses CREB-2 -Together, activating CREB and deactivating CREB-2 transfers short-term memories to long-term -Synaptic marking – the proteins produced in the nucleus know which synapses to go to because of their short-term changes -Proteins must be synthesized locally at the synapses -Dormant mRNA is sent to all the synapses -There is a protein called CPEB that is activated by serotonin and is required by the synapses to maintain protein synthesis -Resembles a prion – special protein with dominant and recessive conformation, dominant can be harmful -Dominant is self-perpetuating – turns recessive into dominant -Explicit memory - depends on the elaborate neural circuitry of the hippocampus and the medial temporal lobe, and it has many more possible storage sites. -Long-term potentiation - synaptic strengthening mechanism in the hippocampus -long-term potentiation describes a family of slightly different mechanisms, each of which increases the strength of the synapse in response to different rates and patterns of stimulation -glutamate acts on two different types of ionotropic receptors in the hippocampus, the AMPA receptor and the NMDA receptor. The AMPA receptor mediates normal synaptic transmission and responds to an individual action potential in the presynaptic neuron. The NMDA receptor, on the other hand, responds only to extraordinarily rapid trains of stimuli and is required for long-term potentiation flow of calcium ions into the postsynaptic cell acts as a second messenger (much as cyclic AMP does), triggering long-term potentiation - allows calcium ions to flow through its channel if and only if it detects the coincidence of two neural events, one presynaptic and the other postsynaptic: The presynaptic neuron must be active and release glutamate, and the AMPA receptor in the postsynaptic cell must bind glutamate and depolarize the cell. -explicit memory in the mammalian brain, unlike implicit memory in Aplysia or Drosophila, requires several gene regulators in addition to CREB -Cognitive science - Kantian notion that the brain is born with a priori knowledge, “knowledge that is … independent of experience.” -Visual system -Different layers respond to different things - each cell in the primary visual cortex responds only to a specific orientation of such light-dark contours -The brain does not simply take the raw data that it receives through the senses and reproduce it faithfully. Instead, each sensory system first analyzes and deconstructs, then restructures the raw, incoming information according to its own built-in connections and rules -What and where are different neural pathways -there is no single cortical area to which all other cortical areas report exclusively, either in the visual or in any other system. In sum, the cortex must be using a different strategy for generating the integrated visual image. -Spatial Map -the hippocampus of rats contains a representation—a map—of external space and that the units of that map are the pyramidal cells of the hippocampus, referred to as “place cells.” -The brain sometimes codes with coordinates centered on the receiver and sometimes relative to the outside world -Attention acts as a filter, selecting some objects for further processing -A modulating circuit involving dopamine in the hippocampus forms spatial maps -The dopamine comes from the cerebral cortex (a higher level part of the brain) -Eric Kandel tried to translate his research into a cure for age-related memory loss -Alzheimer’s: This degeneration of tissue is caused in large part by the accumulation of an abnormal material known as ß-amyloid in the form of insoluble plaques in the spaces between brain cells. -We found that drugs which activate these dopamine receptors, and thereby increase cyclic AMP, overcome the deficit in the late phase of long-term potentiation. They also reverse the hippocampus-dependent memory deficit. -Various disorders are being solved slowly through research -Consciousness -consciousness in people, is an awareness of self, an awareness of being aware. -The brain does reconstruct our perception of an object, but the object perceived—the color blue or middle on the pia no—appears to correspond to the physical properties of the wavelength of the reflected light or the frequency of the emitted sound -Claustrum is connected to a bunch of different brain parts – could regulate attention -viewing frightening stimuli activates two different brain systems, one that involves conscious, presumably top-down attention and one that involves unconscious, bottom-up attention, or vigilance -readiness potential can measure what a person is going to do before they know they want to do it

Do you know what it means to be more than a bank?
For us, being more than a bank means having a presence in places where others would rather not be; it means standing by those who are "out-of-the-way" despite their remoteness; it means encouraging and supporting people's efforts to make a living.
It means machinery in factories, tools in workshops, bread on the table. It means steadfast support for tradesmen, artisans, workers, manufacturers, students.  It means being a neighbor. It means cherishing and protecting them all. It means sharing their dreams and celebrating their successes.
Being more than a bank means a flag flying courageously all over the world and a source of hope, confidence, and pride for millions. It means being a partner in the country's past and a guarantor of its future. Being more than a bank in Turkey means a century and a half of striving with all one's might for the good of the nation, of being a great bank in a great country. It means being Ziraat Bank.
For a hundred and fifty years Ziraat Bank has been more than a bank.

--- title: Japan | Forest Medicine layout: default ---
Did you know that trees emit organic compounds called phytoncides that help them ward off harmful insects and fungi? Studies in Japan have shown that when we breathe in phytoncides while enjoying the quiet of the forest, our bodies create more cancer fighting proteins and immune support cells.
Japan has 62 official Forest Therapy trails. They call this practice of wandering through forests ‘shinrin-yoku’ which roughly translates to ‘Forest Bathing' or 'Taking in the Forest Atmosphere.’ As of 2012, the country had already devoted four million dollars funding related research.
Shinrin-yoku consists of being meditatively present in the forest through slow movements and focus on the senses. 森林浴 – Shinrin-yoku

This recipe couldn't be easier! Make the most of the hedgerows with this tasty jelly recipe.
Break up the gelantine leaves and place in a small bowl and vocer with just enough water to cover. Soak for 1½ hours.
Place the blackberries, water, sugar and lemon juice into a pan over a medium heat. Bring to the boil, then reduce the heat to simmer until the fruit has broken down completely to a sauce.
Place a sieve lined with two layers of muslin over a bowl and strain the blackberry mixture into the bowl. (Don't press the pulp, as this will make for a cloudy jelly.) Once all the liquid has drained through discard the fruit pulp.
Place the collected liquid into a clean pan and cook over a low heat, until just warm, then whisk in the gelatine and water. Make sure you dissolve any lumps.
Remove from the heat and add the sloe gin.
Pour the mixture into a 700ml/1 pint 3fl oz jelly mould and cover with a plate. Chill overnight in the fridge.
To serve, fill a large pan or bowl with hot water to just under the level of the jelly in its mould. Place the mould into the hot water and leave there for no more than 20 seconds.
Place a plate over the top of the mould, remove from the water and turn over. Lift the mould off the jelly carefully and serve. (If the jelly does not come loose, return to the hot water for another ten seconds, then try again.)


Euro 2020 play-off draw made
by BeSoccerUEFA made the draw for the Euro 2020 play-offs. Most of the match ups had already been confirmed, but Hungary, Israel, Romania and Bulgaria were assigned to their play-off path via a draw. In addition, the host of the final in each path has also been confirmed and an additional draw was conducted 30 minutes after the main draw.
Scotland will host Israel in the semi-final of their Nations League play-off in path C while in path A, Hungary will travel to Bulgaria and Iceland will face Romania. This was the result of the draw conducted by UEFA in Nyon, Switzerland.
The full play-off line-up is as follows:
Path A: Iceland v Romania and Bulgaria v Hungary. The winner of Bulgaria v Hungary will host the final.
Path B: Bosnia and Herzogovina v Northern Ireland and Slovakia v Repulbic of Ireland. The winner of Bosnia v NI will be at home in the final.
Path C: Scotland v Israel and Norway v Serbia. Norway or Serbia will be at home in the final.

Path D: Georgia v Belarus and North Macedonia v Kosovo. Semi-final 2 will host the final.
The semi-finals will be played on 26th March and the finals on 31st March.
In addition, there were two additional draws held thirty minutes after the play-offs. One was to found out who will host the head to head clash between Denmark and Russia at Euro 2020 as both teams are in the same group and qualified directly for the tournament. The Danes will have the luxury of playing three games at home.
The other was to determine which group the winners of the path D and path A will go to. This is a result of path A having two hosts (Hungary and Romania) in the play-offs. The winner of path D will go to group C with Ukraine and the Netherlands while the play-off winner from path A will play in group F with Germany.

Athlete of the Month Q&A: Mariner’s Roman Savchuk
It was arguably the highlight of the year in Wesco football.
Mariner senior wide receiver Roman Savchuk sprinted down the sideline on a go route during an Oct. 18 game against Glacier Peak at Veterans Memorial Stadium in Snohomish, and Marauders quarterback Jackson Cole let it fly.
“The corner wasn’t playing very tough and he was kind of bailing, and I already knew it was going to be a jump ball,” Savchuk said. “I feel like I can attack the ball better than most people. Jackson didn’t put it outside the numbers, so I had to put it in my own hands and make a play.”
While the Grizzlies’ defensive back was looking up at the ball, Savchuk, running alongside him, jumped above him and plucked it out of the air, evoking a catch made famous by NFL Hall of Famer Randy Moss.
Savchuk stayed on his feet and coasted into the end zone for a touchdown.
“When I got back to the sideline, everyone was pretty hyped and came up to me and said it was the craziest play they’d seen this season,” he said.
“Roman is pretty darn special,” Mariner coach Mark Stewart said. “We weren’t too surprised (by the catch). He just has an uncanny ability to make plays.”
Stewart referenced a play Savchuk made on defense in an Oct. 25 win over Cascade, when he abandoned his pass-rush responsibilities and baited the Bruins’ quarterback into an interception.
“We moved him up into the box more often this year, and he was supposed to rush on that play but he read the bootleg, dropped back and took the interception to the house,” Stewart said.
Savchuk was voted the Herald’s Athlete of the Month for October, following Cole, who earned the honor for September.
The Herald caught up with Savchuk last week to talk about large families, engineering and a week of team-building in Wenatchee.
Two Mariner football players have been voted Athlete of the Month so far this year. Are you guys doing a lot of campaigning?
Our teachers have been helping a lot and putting it out in front of students. Our family members have been helping a lot, too, and are having everyone in the community vote for us. It feels good that people think about us that way.
Have you made any other catches like that one against Glacier Peak, in games or in practice?
I made two or three last year, but this was the first one that was actually caught on tape.
How would you evaluate your last season of high school football?
I think the season went pretty well. Last year we only had two wins, and this year we had three, so it felt great to win more games. It was a bummer losing to Glacier Peak by one point (21-20), though. It kind of determined whether we were going to make the playoffs or not.
You’re a wide receiver on offense and a safety on defense. Which do you like better?
I enjoy playing both ways, but I would choose defense because I like being physical and hitting people. It feels better to score a touchdown on defense because it’s harder. It’s fun to make plays like the one against Glacier Peak, but not enough action comes on offense. On defense, you can make a play on every play.
 How many brothers and sisters do you have?
I have three brothers (Pavel, Peter and Max) and four sisters (Nadia, Olga, Sofia and Kristina). I’m fifth, in the middle. Three are younger and four are older. There’s always someone to talk to if you need, and we have 2-on-2 basketball games a lot. We all play sports, and Max was our backup quarterback this season.
What are your plans for after high school?
Hopefully I’ll be able to somehow sneak in an offer to play football somewhere. I’d like to do engineering, designing buildings and stuff.
Outside of football, what else are you passionate about?
All I do is play sports. If I’m not at practice, I’m somewhere playing sports with friends, either on someone’s sport court or at the (Mukilteo) YMCA.
When you look back on your time playing sports at Mariner 5-10 years from now, what do you think you’ll remember most?
I’ll just remember making memories with my teammates. We went to a football camp in Wenatchee last summer and did so much fun stuff together. I’m never going to forget about that.

Posted on July 14, 2016
Between 2007 and 2010, Chicago dumped nearly 19 billion gallons of untreated sewage mixed with storm water into Lake Michigan.
At the time of the founding of the City of Chicago, the Chicago River was utilized as the main source of fresh drinking water for the city's population. However, after heavy polluting of the river, this water source quickly became unfit for human consumption and remains remarkably contaminated today.
The Chicagoland region possesses one of the highest lead rates in the country. After testing in 2016, nine regions around the Chicago region were found to exceed the Environmental Protection Agency's standard for lead quantity. The testing of these water systems, including those in Berwyn, Forest View, York Township, and more, showed more than 15 parts per billion of lead in the tap water were found.
In 2015, the Metropolitan Water Reclamation District revealed high levels of bacteria from human waste at more than a dozen spots throughout the City of Chicago. This organization is a taxpayer funded agency that handles Cook County's sewage and stormwater. The majority of the contamination of the Chicago River and Lake Michigan around Chicago is a direct result of the flooding of the city's sewage system.
Even after countless attempts to fix the problem, Chicago remains the poster child for failing sewer systems in the Great Lakes Basin.
Completed in 1866, Chicago's sewage system has been plagued with problems, including flooding following large storms. When heavy rains exist, the resulting stormwater can overwhelm the sewage treatment facilities. The Chicago Sewage System has been experiencing flooding problems since its creation in the nineteenth century. Along with human waste, when it rains, the sewer systems also collect the rainwater.
Cities then respond by dumping the bacteria-laden mix of stormwater and untreated sewage into the nearest surface water to prevent the filth from backing up in basements and flooding streets. Consequently, the majority of the pollution in the Chicago River and Lake Michigan result from this waste dumping. Because the City of Chicago receives regular rain, often experiencing large storms, this problem is very prevelent and is likely to persist.
Why has Chicago not solved this long lasting problem with its sewage systems? When Chicago receives rainfall, it most often occurs in heavy amounts rather than slight drizzles. It is difficult for any man-made sewage system to handle these rain events. Furthermore, because this 4,400 mile long sewage system has been in place for over a century, it would be nearly impossible to reinstall a completely new sewage system. So, what can we as individuals do to reduce the waste in our water?
You CAN make a difference!
How can an individual person make that much of a difference if Chicago is such a large city? Although tackling the problem of Chicago's sewage system may seem daunting, there are many ways that YOU can help make this city a better place to live. The following are actions that the individual can take to help prevent flooding and waste dumping from the sewage system in Chicago:
- Incourage the collection of rain water. You can collect run-off water in rain barrels, or even large tanks.
- Create a rainwater garden. Rainwater gardens harvest the rain from your roof or gutters to create a water garden or to water the immediate garden area. This is a simple and visually appealing way to prevent flooding.
- Use rain chains instead of traditional downspouts. Rain chains are decorative alternatives to conventional downspouts that guide the rain from your roof, down the chain, and into your garden, watering can, or rain barrel.
- Install gutter systems that do not lead direclty to sewers.
- Ensure that your sewers receive regular inspections and cleanings.
- Recycle to keep trash out of landfills.
- Use reusable materials, such as resusable containers, waterbottle, and recycled materials.


CLEAN SLATE A Film Review by James Berardinelli Copyright 1994 James Berardinelli
Rating (0 to 10): 5.1
Date Released: 5/6/94 Running Length: 1:46 Rated: PG-13 (Language, sexual situations)
Starring: Dana Carvey, Valeria Golino, James Earl Jones, Kevin Pollak, Michael Gambon, Michael Murphy Director: Mick Jackson Producers: Richard D. Zanuck and Lili Fini Zanuck Screenplay: Robert King Music: Alan Silvestri Released by MGM
Consider this premise: a private investigator (Dana Carvey) who's a key witness in an upcoming trial has a memory problem. Not only can't he recall the crimes of the man he's supposed to testify against, but he can't remember things from day to day. Every time he goes to sleep, his amnesia asserts itself, wiping out events, places, and people. So, every night before he goes to bed, he uses a cassette recorder to tape instructions to himself - basic facts of life to get him through the day.
Add to this a beautiful woman who is supposed to be dead (Valeria Golno), a mobster with a British accent (Michael Gambon), and a doctor who seems to know things that no one else does (Michael Murphy), and the seeds are there for a decent thriller - or a hilarious comedy. Unfortunately, CLEAN SLATE is neither. For all its promise and possibilities, this film manages to be nothing more than forgettable.
As far as featherweight entertainment goes, this isn't bad. The script is peppered with funny moments, although probably less than half the jokes actually click. CLEAN SLATE works better when its humor isn't too outrageous - the climactic trial scene is more silly than enjoyable because it's so completely over-the-top (lawyers, bailiffs, and courtroom observers pile atop each other in the middle of a free-for-all melee).
One of the most disappointing things about this film is that it could have been so much better, either as a mystery or a comedy. Only on one or two occasions is the central plot device of amnesia used to its full potential. Whichever way the filmmaker chose to play CLEAN SLATE - for laughs or thrills - it would seem they had a winner. Yet, mysteriously, the result is a unsatisfying mix of a hard-to-swallow gumshoe tale and a pedestrian comedy.
The cast is solid. Although you occasionally expect him to start imitating George Bush, Dana Carvey brings a welcome likability to Maurice Pogue, the man with no memory. Valeria Golino, known best as Charlie Sheen's girlfriend from the two HOT SHOTS films, again functions as the token female love interest. James Earl Jones enjoys himself in this comic turn, while bringing a touch of class to CLEAN SLATE. Other performers include Kevin Pollak, Michael Gambon, and Olivia D'Abo.
The first act, where the audience is finding things out along with Pogue, is the most entertaining segment of the film. For the first forty-five minutes, the script cleverly forces the viewers to identify with the main character. It's almost - albeit not quite - a first-person motion picture. Certainly, Pogue is in every early scene. Then he goes to sleep and forgets everything, but the audience remembers, and the effect is ruined. Now Pogue's memory loss seems like what it is - a device to set up jokes and move the story along.
There are some worthwhile running gags, including the local blind man's "joke of the day", a painter's continuing attempts to render a Mona Lisa likeness on the side of a building, and the misadventures of a dog with depth perception problems. None of these, however, make up for what CLEAN SLATE is missing.
This film is likeable, if not especially worthwhile. Admittedly, Dana Carvey is a more engaging screen presence than his former SATURDAY NIGHT LIVE co-star Mike Myers, but there's little in the way of breakthrough comedy in his latest feature. With CLEAN SLATE, the lackluster results speak of a wasted opportunity.

Logisc Regression
Logisc regression is used to deal with classiﬁcaon problems. It is diﬀerent from basic linear regression by
dot product; the monotonic transform [3] makes the output to a probability in [0,1].
Some examples of the
praccal applicaon of Logisc regression are predicng the risk of developing a given disease, cancer
diagnosis, predicng mortality of injured paents, and in engineering for predicng the probability of failure of
a given process, system, or product. Logisc regression takes a monotonic transform of a simple linear
regression as following.
log
(
p
(
X
)
1
−
p
(
X
)
)
=
β
0
+
β
1
X
where
p
(
X
)
is a probability of event X happen in a two classes classiﬁcaon
problem.
Instead of minimizing error, logisc regression maximize the likelihood of the probabilies where the
transform funcon is
e
β
0
+
β
1
X
1
+
e
β
0
+
β
1
X
which always outputs a number between [0,1] as a probability.
When it is generalized to mulple variables [3], it is the Soﬅmax funcon to handle mul-classes (C)
classiﬁcaon problems.
soﬅmax( i ) =
e
Z
i
∑
j
=
1
C
e
Z
j
for i = 1, 2, …, C
where
Z
i
are the regressed outputs from its inputs, and soﬅmax( i ) are the transformed outputs as the
probabilies.

1 “Call now; is there anyone who will answer you?
To which of the holy ones will you turn?
2 Surely vexation kills the fool,
and jealousy slays the simple.
3 I have seen the fool taking root,
but suddenly I cursed his dwelling.
4 His children are far from safety;
they are crushed in the gate,
and there is no one to deliver them.
5 The hungry eat his harvest,
and he takes it even out of thorns,
and the thirsty pant after his wealth.
6 For affliction does not come from the dust,
nor does trouble sprout from the ground,
7 but man is born to trouble
as the sparks fly upward.
8 “As for me, I would seek God,
and to God would I commit my cause,
9 who does great things and unsearchable,
marvelous things without number:
10 he gives rain on the earth
and sends waters on the fields;
11 he sets on high those who are lowly,
and those who mourn are lifted to safety.
12 He frustrates the devices of the crafty,
so that their hands achieve no success.
13 He catches the wise in their own craftiness,
and the schemes of the wily are brought to a quick end.
14 They meet with darkness in the daytime
and grope at noonday as in the night.
15 But he saves the needy from the sword of their mouth
and from the hand of the mighty.
16 So the poor have hope,
and injustice shuts her mouth.
17 “Behold, blessed is the one whom God reproves;
therefore despise not the discipline of the Almighty.
18 For he wounds, but he binds up;
he shatters, but his hands heal.
19 He will deliver you from six troubles;
in seven no evil shall touch you.
20 In famine he will redeem you from death,
and in war from the power of the sword.
21 You shall be hidden from the lash of the tongue,
and shall not fear destruction when it comes.
22 At destruction and famine you shall laugh,
and shall not fear the beasts of the earth.
23 For you shall be in league with the stones of the field,
and the beasts of the field shall be at peace with you.
24 You shall know that your tent is at peace,
and you shall inspect your fold and miss nothing.
25 You shall know also that your offspring shall be many,
and your descendants as the grass of the earth.
26 You shall come to your grave in ripe old age,
like a sheaf gathered up in its season.
27 Behold, this we have searched out; it is true.
Hear, and know it for your good.”

The Bollywood diva, who known for her sense of fashion took to social media to share a handful of glimpses which are screaming glamour.
The 46-year-old diva still gives young actresses a run for their money with her well-toned body and impeccable sense of style. She even grabs everyone's attention with chic athleisure whenever she steps out for her workout sessions.
In her latest photoshoot, she can be seen donning a shimmery silver outfit with statement earrings and tresses all set back in a pony. She completed her with similar coloured metallic shoes.
Meanwhile, the diva is also grabbing a lot of attention for her relationship with Arjun Kapoor, whose recent release 'Panipat' has been doing wonders at the box office.

Jake Paul slams 'butt hurt' fans after hanging out with ex Erika Costell
Jake Paul has slammed ‘butt hurt’ fans after he was criticised for hanging out with his ex-girlfriend Erika Costell.
Ouch.
The YouTube star, who married Tana Mongeau earlier this year, caused a bit of a stir after he was spotted out in LA with his ex various times over the past few months.
With a fan asking him why they were together during an Instagram Q and A, Jake looked exasperated.
‘Exes can be friends, right?’ he asked. ‘Or just because “stans” don’t like that and get butt hurt we’re not supposed to be?’
Well, that’s that then.
Drama was stirred up again after a fan spotted the pair of them together in a car, snapping a photo.
The 22-year-old split from Erika back in November 2018, after just six months of officially dating.
Advertisement Advertisement
Jake went on to say he could ‘barely hold it together’ in a statement after the public break-up.
‘Erika is such a beautiful soul & she truly changed my life,’ he wrote. ‘She is a powerful, smart & independent woman, who has such a bright future ahead of her and has helped me become a better person on multiple levels.
‘The times we had together are irreplaceable and I will be forever grateful that she was part of my life.’
Then, back in August, just weeks after he married his beau Tana, Team 10’s Sunny Malouf casually posted a video of herself and the pair lip-syncing to Snoop Dogg, Bruno Mars and Wiz Khalifa’s track Young Wild And Free.
Bit awkward.
Tana made her feelings clear on the reunion when she tweeted: ‘Lmao wtf,’ before her ex-girlfriend Bella Thorne weighed in on the situation.
Advertisement Advertisement
She went on to appear on Bella’s Instagram Stories, giggling as she parodied Ariana Grande’s Thank U, Next about her exes.
‘Thought I’d end up with Bella, yet it wasn’t a match,’ she sang. ‘Wrote some songs about Hunter, now I listen and laugh.
‘Even actually got married and for Jake I’m so thankful, except when he goes out to lunch with his ex and I find out on Twitter.’
Real talk though, it’s a bop.

Coulsdon C of E Primary School in Surrey is part of the Coulsdon Cluster, a group of 7 primary and 2 secondary schools which meets twice a term to plan inter-school competitions and share good practice. The sports coach employed by the cluster shares expertise with all the schools, and the primary pupils enjoy a much wider range of activities than would usually be available, through their use of the secondary schools’ sports resources.
Wickersley St Alban’s C of E Primary School in Yorkshire gets many benefits from its partnership with the local secondary school (Wickersley School and Sports College), including:
New College Leicester shares its specialist sports facilities with some leading community sport clubs. These clubs have in turn provided expert coaches to run satellite sports clubs at the college’s 6 partner primary schools, to encourage younger children to continue participating in sport long after they’ve left school.

I just wanted to say thank you. Thanks for all the support you give during these issues in the support forum, whether it's from me or from others. Even when I don't ask questions on my own, I learn a lot from reading your suggestions to other users.I can customize it with my pictures.
Your product is affordable, I love the customizations I can do with it, and it works. I've been a customer of yours for years, so I've seen you grow and have witnessed the changes from minor updates to major updates.I love how it matches my web design and I can customize it with my pictures.
Wow what an awesome software package. Easy to use; easy to install; seamless match with Paypal. After a year still no issues. Even amazing considering I installed it and I’m not much of a web person. I love how it matches my web design and I can customize it with my pictures.

Observables are a rather flexible mechanism and allow for many different styles of programming with very different properties.
It seems that often people learn only a style or two and have misconceptions about the properties of observables.
The intended audience for this is programmers recently introduced to Observables.
I assure you that it was not all immediately obvious to me when I first learned of observables.
Give a sense of the depth and breadth of programming with observables...
...by briefly discussing a few different ways to program with observables.
No claim is made regarding the completeness of this treatment!
interface Observable<T> {
subscribe(observer: Observer<T>);
unsubscribe(observer: Observer<T>);
}
interface Observer<T> {
onValue(value: T): void;
onError(error: any): void;
onEnd(): void;
}
constant(value)
error(value)
o1.flatMap(v => o2)
combine([...os])
merge([...os])
o.scan((s, x) => s1, s0)
o.debounce(ms)
o.skipDuplicates(equals)
Asynchronous operations, time, state are very difficult
Observables can make such code more declarative
Observables are highly composable (4+ monads)
Like what you do with async-await
Linear thread of control with asynchronous ops
const foo = async (...xs) => {
const r = await bar(...xs)
return baz(r)
}
const mapAsync = async (fnA, xs) => {
const ys = []
for (let i = 0; i < xs.length; ++i)
ys.push(await fnA(xs[i]))
return ys
}
o1.flatMap(v => o2)
— to awaitconstant(v)
— to introduce constantssubscribe(observer)
— to startfromNodeCallback(fn)
— interoplazy(() => o)
— to avoid over eagernessconst lazy = toObservable =>
constant(undefined).flatMap(() => toObservable())
const foo = (...) => lazy(() =>
bar(...)
.flatMap(r =>
constant(baz(r))))
const mapObs = (fnO, xs) => lazy(() => {
const ys = []
const loop = i => lazy(() => {
if (i < xs.length)
return fnO(xs[i])
.flatMap(y => {
ys.push(y)
return loop(i+1)
})
else
return constant(ys)
})
return loop(0)
})
Observables compose
Observables are cancellable
And observables can do other things beyond promises
Something has happened or something has changed
Examples
This is probably what comes to mind when you think of observables?
merge([...os])
— gather eventso.scan((s, v) => s1, s0)
— stateupdate(...)
— generalization of scan
o1.flatMap(v => o2)
— do async after evento1.flatMapConcat(v => o2)
— don't dropfromEvents(target, name)
— interopMuch preferable to traditional use of callbacks
Powerful combinators for dealing with time
What something is
Independence from time
Source of truth
o.map(i => o)
— derived propertyo1.flatMapLatest(v => o2)
— async derivedcombine([...os])
— derived from many propsexport default U.withContext(({phase}, {user_state}) => {
const done = US.doneCount(phase, user_state)
const total = US.itemCount(phase, user_state)
const percentage = U.round(U.multiply(U.divide(done, total), 100))
const completed = U.ifte(U.equals(done, total), "completed", "")
return <div className={U.string`progress ${completed}`}>

<div className="progress__progressed"
style={{width: U.string`${percentage}%`}}/>

{done}/{total} valmis

})
Simple — just map
Stateless properties are RT — can be reconstructed
Time is largely out of the equations
Robust — skip, dup, ... don't matter much
Often less boilerplate
Different mode of thinking
Direct-style
f(x1, x2)
x + y * z
R.add(x, R.multiply(y, z))
Monadic-style
x1.flatMapLatest(x1 =>
x2.flatMapLatest(x2 =>
constant(f(x1, x2))))
Cumbersome, isn't it?
combine([x1, x2], f)
As good as it gets?
const lift = f => (...xs) => combine(xs, f)
const fL = lift(f)
fL(x1, x2)
const ifte = (c, t, e) =>
c.flatMapLatest(c => c ? t : e)
Can be significantly more legible than monadic-style
Need to lift combinators for legibility
Gotchas with lifting techniques — need to fully apply
More limited — you'll occasionally need monadic-style
Side-effects
Asynchronous HTTP requests
In response to events or state changes
Also just async programming on backend (skipped)
o1.flatMapLatest(v => o2)
— do async IOo.debounce(ms)
— avoid too many requestso.throttle(ms)
— avoid too many requestsfromPromise( ??? )
fromBinder(subscribe)
or stream(emitter => ...)
— wrap XMLHttpRequest
Observables are (typically) push-based: An observable (source) synchronously calls the observer (sink)
What if observer is not ready? What about concurrency? Locking?
Back pressure - complex with pushy-style
Pull-style puts consumer in charge
Pull-style is fundamentally different, dual
Glitches
Recursion limitations
Observables are like asynchronous message passing
Rendezvous, like in CSP, is not directly supported
