Orca is an esoteric programming language, designed to create procedural sequencers in which each letter of the alphabet is an operation, where lowercase letters operate on bang, uppercase letters operate each frame. It was created by hundred rabbits, a research studio on a sailboat.
Orca is not a synthesizer, but a flexible livecoding environment capable of sending MIDI, OSC & UDP to your audio/visual interfaces, like Ableton, Renoise, VCV Rack or SuperCollider.
For the purposes of this site, we've connected some drum racks and synthesizers from Enfer in the bottom right and are patching them in as virtualized midi instruments. Normally, Orca will not make sound on its own, and rather just sends messages or data to external devices or programs. Orca and Enfer are both creations of Devine Lu Linvega.
Orca utilizes a unique base-36 number system:
Here is a table to make it clear:
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
| C | D | E | F | G | H | I | J | K | L | M | N |
| 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 |
| O | P | Q | R | S | T | U | V | W | X | Y | Z |
| 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 |
Anytime you want to give a numeric value, you can give a letter as well.
Operators are mostly letters, and a few symbols. An operator takes up one cell in the grid. Most operators have some type of input or output on one of their adjacent tiles. Some operators are capable of moving; others stay put. You can see a guide referencing the operators by pressing CmdOrCtrl+G
Operators come in two main flavors: lower-case and upper-case. Lower-case letters will operate on every bang, and upper-case letters will operate on every frame.
Most operators take some number of inputs and produce some number of outputs. The inputs and outputs are generally going to be on the top, bottom, or sides of the operator.
For example, take the D operator. It has two inputs and one output.
Other operators have a larger number of inputs an outputs. For example, take X - it has three inputs and one output:
Bangs are what makes thing happen. Many operators only get triggered when they there is a bang operator adjacent to them. The bang operator itself is a * character. For example, the D operator causes a bang on an interval at its bottom location. Any adjacent operator will be triggered if it is next to that particular cell.
Orca has a few relevant components related to timing:
The clock can be started and stop with the spacebar. If a midi device is connected as an input, the clock will be set from the midi device, and Orca will respond to midi start and stop messages.
For each tick of the clock, we move forward a frame. Frames can be skipped or rewound with an Orca command if needed, too. The current frame number can be seen in the bottom right of the window.
The tempo, as expected, determines the BPM and rate that the clock will tick. There are some relevant shortcuts as well:
Frame By Frame........... CmdOrCtrl+F
Reset Frame.............. CmdOrCtrl+Shift+R
Incr. Speed.............. >
Decr. Speed.............. <
Incr. Speed(10x)......... CmdOrCtrl+>
Decr. Speed(10x)......... CmdOrCtrl+<
For the purposes of learning, the easiest way to start making some sound is by using the midi operator. The midi operator takes five inputs. It has zero Orca outputs but as you might expect, sends a midi message to a midi device.
The midi operator interprets any letter above the chromatic scale as a transpose value, for instance 3H, is equivalent to 4A.
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B |
|---|---|---|---|---|---|---|---|---|---|---|---|
| _ | _ | _ | _ | _ | _ | _ | _ | _ | _ | A0 | B0 |
| C | D | E | F | G | H | I | J | K | L | M | N |
| C0 | D0 | E0 | F0 | G0 | A0 | B0 | C1 | D1 | E1 | F1 | G1 |
| O | P | Q | R | S | T | U | V | W | X | Y | Z |
| A1 | B1 | C2 | D2 | E2 | F2 | G2 | A2 | B2 | C3 | D3 | E3 |
However, you'll need to somehow send a bang to the operator.  An easy one to start with is the D (delay) operator.
Try adding the following:
.D......
..:03cf5
and making sure the clock is on by pressing space. Boom! We've made our first notes. Quickly, I'm sure you'll find a single repeating note annoying.
Don't forget you can press space to turn on or off the clock. Why don't we add some chaos?
We can add a random note value by using the R (random) operator.
So, lets try putting it above our note argument:
.D..aRf.
..:03cf5
We can also create something interesting by varying regularly. One useful operator for this is the C (clock) operator.
Try running the following:
..C.....
.D..aRf.
..:03cf5
Now lets make two of them! Remember you can drag with the mouse or just use the arrow keys and shift to select a section. After that, simply copy and paste to a new section. Let's also make some changes:
..C.....
.D..aRf.
..:03cf5
........
........
.D2.aRf.
..:02cf5
Now we have a somewhat interesting mixture of regularization, and randomization.
What if we wanted to specify a particular sequence of notes, rather than choosing them randomly?
One of the most essential operators for sequencing is the T (tracker) operator. The T operator takes at minimum 3 inputs. We say at minimum because one of the arguments determines how many arguments there are on the right side.
T operators are nice because we can specify a sequence of notes that we are interested in and we can also control how often we change between them, as well as which ones we want to change to. Let's start by establishing an interesting or fun sequence with the T operator, then moving the operand it produces down into the note selection area for a midi operator. Here's what we'll do:
...C...........
...68TCFGACFE..
..C..E.........
.D6..J.........
..:32Ef5.......
Wait! It sounds different. Note that we also changed the midi operator's channel and octave. We're now sending a much lower note to a different instrument. Try changing it yourself.
There are few operators for give us some basic math skills. These will prove invaluable when adding nuance to your creation. The first is the A operator, which, maybe predictably, is for addition:
After that, we have the B operator, which takes the difference of two operands:
One other simple operator that is really useful for adding some nuance is the F operator. The F operator checks for equality, and bangs if its true.
Devine has conveniently added drum samples to the first octaves of the voices in Enfer which is where our synthesizers and sounds are actually coming from. Let's add a kick, snare, hi-hat and lead to our previous bass line.

With that, we've made our first little tune!
As you can probably imagine, sometimes things can get a little crowded. Two operators we can use to space things out are the J (jumper) and Y (jymper) operators.
The Y operator moves an operand from the left to the right:
The J operator moves an operand from the top to the bottom:
We can use these when things start to feel too tight - or if you need to move an operator around a bit.
When you're trying to read or write further away, there are two operators that are particularly relevant:

--- title: "Dancing" layout: single excerpt: "The Rossi Gang: A short reprieve from science" read_time: false header: teaser: RosettaThumb.jpg ---
Last summer, I had the opportunity to help out with a Music Video Release as a Swing Dancer. The Carlo Rossi Gang is an extremely talented New Orlean's style jazz band based in Vancouver. Different than what I usually collaborate on, but definitely a fun experience.
Check out the final product below!


I've noticed some strange behaviour from one of my EmonTX Low Power Temperature Nodes. All has been working perfectly for a few months, but then one node started sending exactly the same temperature for a period four hours. When seeing this in emoncms I thought this was unlikely to be a true measurement of actual temperature, but as the data then went back to the normal pattern I just dismissed it as a fluke. However a day or so later I noticed large gaps appearing in the data recorded in emoncms.
Gaps in the data could be a problem with reception, but four hours of the same data seems to be a problem with the emontx node. The battery voltage is stable at 2.95v. For now I have just removed and replaced the battery to allow the node to reset and at the moment the data is coming in consistently every minute.
I wondered if anybody else has experienced this issue and what the problem might be.
Re: Strange Behaviour from EmonTX temperature node
This might sound silly, but are you sure it did send the same data all along ?
If the radio link fails (too much noise) and no data is received, this can be displayed as a flat curve in the charts.
Just asking.
Re: Strange Behaviour from EmonTX temperature node
Hi Jérôme,
Thanks for responding.
I'm positive its data received, I've exported to CSV and checked there is data for every minute during the period and it's four hours of exactly the same temperature. Also I looked at the battery voltage data for the same node / period and every minute there is data, which is NOT all the same. So I don't think this issue is to do with the radio link, but perhaps a read error to the temperature sensor?
As for the subsequent gaps in the data; this has never happened before. I have had consistent data every minute for three months with only the very occasional missed data point.
Interestingly and I think / hope unconnected there is someone else (obviously local) who is transmitting data that showed in my inputs. The nodes where different and it disappeared thereafter as I assume they changed their network group. This was a week or so earlier than my problem so I don't think it is connected, but what's your view?
Re: Strange Behaviour from EmonTX temperature node
"The battery voltage is stable at 2.95v."
There is your problem. The DS18B20 has a minimum supply voltage of 3.0 V, so it is not guaranteed to work at 2.95 V.
(And if your meter is reading high, the true voltage could be less than that).
I suspect what is happening is this: it has an internal scratchpad memory that stores the reading. It's possible that the scratchpad is supplying a stored reading but not getting updated due to the low supply voltage.
Re: Strange Behaviour from EmonTX temperature node
Robert,
I take your point about the voltage and thanks for the feedback, but I'm now confused about the battery life of the low power temperature node. If 3.0 V is the minimum reliable voltage for the DS18B20 and the data sheet confirms that’s the minimum, then how can the batteries last 138 days with data taken every 10 seconds as implied by the sketch. When I started out on this I assumed 2.2 volts was the minimum voltage as that is the low battery level set in the sketch.
I vaguely remember reading something on this site about using the sensor at low voltages (2.7 V if my memory serves) specifically to show the validity of the low power temperature node, however I can't find that page anymore.
I have now measured the voltage with a meter as 2.95V the same as that reported by the node. For reference the same meter measures 3.17V on brand new batteries with no load. Since I'm only switching the sensor on once a minute and not every 10 seconds I would expect better life than 70 days.
If the voltage is indeed the issue then would it not be better to design the low power temperature node around three AA batteries? And I guess the next question would be, is that as simple as it sounds, can I just power it with three batteries? At least then the voltage would have some margin to drop from 4.5V before hitting the minimum of that required by the sensor.
Incidentally since I pulled the batteries and re-inserted them the node is working perfectly, but I have now modified the sketch so I can detect when the temp variable is not being updated.
Re: Strange Behaviour from EmonTX temperature node
"Incidentally since I pulled the batteries and re-inserted them the node is working perfectly,"
That says to me you had some corrosion on the battery contacts, and you had an excessive drop across the resulting contact resistance when it turned on to measure the temperature and transmit. So in the period it was active, the actual working voltage would have been somewhat less than 2.95 V.
You can't use 3 cells because of the upper voltage limit of the RFM12B radio module at 3.8 V, so you're stuck with 2, I'm afraid. I didn't design the sketch, so I can't comment specifically, but my guess is it was found to work down to 2.2 V. That doesn't affect what the data sheet says in any way: it is only guaranteed to work within spec (in all respects) down to 3.0 V. I've no idea which aspects of its performance go out of spec as the voltage reduces, it may well be things that are not important in this application.
Re: Strange Behaviour from EmonTX temperature node
There is no sign of any corrosion on the contacts and I guess for now I need to monitor the issue and see if it reoccurs. If it does continue to be a problem I will have to rethink what I’m doing. I have a Nanode RF running as a web accessible PID temperature controller and it’s using the inside, outside and boiler temperatures from battery powered nodes as process variables, so I don’t want these failing this early in their battery life.
I was toying with the idea of buying an ononGLCD, so one more reliable solution could be to use that to monitor the inside temperature with mains power and re-write my controller so it will still work if either the outside or boiler temperature nodes go down.
Re: Strange Behaviour from EmonTX temperature node
My digital camera has the same problem: no visible corrosion but when the rechargeable NiMH cells aren't freshly charged, it says 'low battery'. Flip the cover open and twiddle the cells a bit and it's quite happy.
The only thought that might help: take a look at JeeLabs. I think it's there I've seen about using a single cell and a step-up regulator. I can't tell you any more than that - it was many months ago I saw it.
You could also try a large capacitor across the 3.3 V supply - it might help if it really is contact resistance that is causing the problem.
Re: Strange Behaviour from EmonTX temperature node
Just thought about using 2 Nickel oxyhydroxide batteries such as Duracell Power Pix they're obviously more expensive than alkaline at £1 each, but with 1.7V nominal they should have a longer life before reaching the minimum voltage for the sensor. Might actually be cheaper than potentially having to ditch alkaline batteries every time the node gets down to 3.0V.
Worth trying if the problem persists.
Re: Strange Behaviour from EmonTX temperature node
Sorry Robert,
I didn't see your last post before I made my comment about alternative chemistry batteries. You make a valid point I've had a similar problem with TV remote controls, just twiddle the batteries and it starts working again.

[gecode-users] Cutting holes within a view optimally

Just as a side-note, you can do propagation earlier than when a variable is
fixed for this constraint. In the ground case, an offset1 of 5 and a value v
of x0 gives a forbidden region
[-----v-----]
for the variable x1. If the difference between min (a) and max (b) of a
non-ground x0 is less than offset1, then all potential forbidden regions
will overlap. Consider the case where b-a=3
[-----a---[==]---b-----]
The doubly marked values are forbidden for x1 regardless of the final value
of x0.
Whether modifying the propagation helps for solving your problem is another
issue of course.
Cheers,
Mikael

TwitterApiClient is an customize version of real TwitterApiClient that exists inside Twitter SDK. We create a customize one to handle edit GsonBuilder and add our custom registerTypeAdapter. We have a problem with Retrofit and Gson.Gson doesn’t know that RealmList ist just a wrapper class. So that's why we made a our custom JsonSerializer and JsonDeserializer for User and Tweets Model. Because these two models are used inside Followers and UserTweets Models as List so they couldn't be casted into normal List<> class

People who think they know everything are a great annoyance to those of us who do. Isaac Asimov
L'intelligence, c'est comme les parachutes, quand on n'en a pas, on s'écrase. Pierre Desproges


Guinevere Directed by: Audrey Wells Starring: Sarah Polley, Stephen Rea, Jean Smart, Gina Gershon Running time: 104 minutes My rating (5 star scale): ****1/2
Harper is the younger daughter of a family of lawyers.  She meets the wedding photographer who is the only person there, including her family, to pay any attention to her. Although he is 30 years older than her, soon she is spending time with him and secretly moves in with him, after telling her parents she didn't get into Harvard after all.
Connie, the photographer, insists she learn to do something artistic and decides to teach her how to take photos. Harper soon learns that she is not the first young woman Connie has educated in this fashion. And she doesn't seem to mind. But this is the kind of relationship doomed to failure and how it fails is what interests us. As Harper says, if you learn from your mistakes, this was a great learning experience.
Polley is brilliant in this role, playing a naive girl who grows into a self-confident woman. Rea does a great job as the fragile older man who seduces younger woman not merely for the obvious physical reasons but for much deeper psychological purposes. And Jean Smart gives a staggering performance as Harper's mother, who can't really do anything to stop her but who knows exactly what is happening and why. Her confrontation with Connie is the highlight of the film.
This is a movie packed with strong character development and great scenes. Funny scenes like the fortune cookie reading at Harper's birthday dinner at her home, to tragic scenes like the final parting between Harper and Connie. Unfortunately, some of the minor roles (Gina Gershon as an exlover of Connie's) are rather weak. And it seems unlikely that Harper would be so artistically talented. But this is compensated for by the insights into Harper's family, who bring new levels of meaning to the word dysfunctional, and into Connie's psychology.
The age difference between Harper and Connie has you seeing Connie as a dirty old man. And he is. But by the time the movie ends, you've come to forgive him his seductions and realize he is as much a victim as anyone. The young women he seduces will leave him and go on to greater things. But he is stuck with who and what he is.
This is not as great a film as Polley's previous film The Sweet Hereafter. But it does give her an opportunity to stretch further as an actress and to play a complex and interesting character. I'm really looking forward to what she does next and even if you're not a fan, you should see this film.

JavaScript Operators Reference
JavaScript operators are used to assign values, compare values, perform arithmetic operations, and more.
JavaScript Arithmetic Operators
Arithmetic operators are used to perform arithmetic between variables and/or values.
Given that y = 5, the table below explains the arithmetic operators:
| Operator | Description | Example | Result in y | Result in x | Try it |
|---|---|---|---|---|---|
| + | Addition | x = y + 2 | y = 5 | x = 7 | Try it » |
| - | Subtraction | x = y - 2 | y = 5 | x = 3 | Try it » |
| * | Multiplication | x = y * 2 | y = 5 | x = 10 | Try it » |
| / | Division | x = y / 2 | y = 5 | x = 2.5 | Try it » |
| % | Modulus (division remainder) | x = y % 2 | y = 5 | x = 1 | Try it » |
| ++ | Increment | x = ++y | y = 6 | x = 6 | Try it » |
| x = y++ | y = 6 | x = 5 | Try it » | ||
| -- | Decrement | x = --y | y = 4 | x = 4 | Try it » |
| x = y-- | y = 4 | x = 5 | Try it » |
For a tutorial about arithmetic operators, read our JavaScript Arithmetic Tutorial.
JavaScript Assignment Operators
Assignment operators are used to assign values to JavaScript variables.
Given that x = 10 and y = 5, the table below explains the assignment operators:
| Operator | Example | Same As | Result in x | Try it |
|---|---|---|---|---|
| = | x = y | x = y | x = 5 | Try it » |
| += | x += y | x = x + y | x = 15 | Try it » |
| -= | x -= y | x = x - y | x = 5 | Try it » |
| *= | x *= y | x = x * y | x = 50 | Try it » |
| /= | x /= y | x = x / y | x = 2 | Try it » |
| %= | x %= y | x = x % y | x = 0 | Try it » |
For a tutorial about assignment operators, read our JavaScript Assignment Tutorial.
JavaScript String Operators
The + operator, and the += operator can also be used to concatenate (add) strings.
Given that text1 = "Good ", text2 = "Morning", and text3 = "", the table below explains the operators:
| Operator | Example | text1 | text2 | text3 | Try it |
|---|---|---|---|---|---|
| + | text3 = text1 + text2 | "Good " | "Morning" | "Good Morning" | Try it » |
| += | text1 += text2 | "Good " | "Morning" | "" | Try it » |
Comparison Operators
Comparison operators are used in logical statements to determine equality or difference between variables or values.
Given that x = 5, the table below explains the comparison operators:
| Operator | Description | Comparing | Returns | Try it |
|---|---|---|---|---|
| == | equal to | x == 8 | false | Try it » |
| x == 5 | true | Try it » | ||
| === | equal value and equal type | x === "5" | false | Try it » |
| x === 5 | true | Try it » | ||
| != | not equal | x != 8 | true | Try it » |
| !== | not equal value or not equal type | x !== "5" | true | Try it » |
| x !== 5 | false | Try it » | ||
| > | greater than | x > 8 | false | Try it » |
| < | less than | x < 8 | true | Try it » |
| >= | greater than or equal to | x >= 8 | false | Try it » |
| <= | less than or equal to | x <= 8 | true | Try it » |
For a tutorial about comparison operators, read our JavaScript Comparisons Tutorial.
Conditional (Ternary) Operator
The conditional operator assigns a value to a variable based on a condition.
| Syntax | Example | Try it |
|---|---|---|
| variablename = (condition) ? value1:value2 | voteable = (age < 18) ? "Too young":"Old enough"; | Try it » |
Example explained: If the variable "age" is a value below 18, the value of the variable "voteable" will be "Too young", otherwise the value of voteable will be "Old enough".
Logical Operators
Logical operators are used to determine the logic between variables or values.
Given that x = 6 and y = 3, the table below explains the logical operators:
| Operator | Description | Example | Try it |
|---|---|---|---|
| && | and | (x < 10 && y > 1) is true | Try it » |
| || | or | (x === 5 || y === 5) is false | Try it » |
| ! | not | !(x === y) is true | Try it » |
JavaScript Bitwise Operators
Bit operators work on 32 bits numbers. Any numeric operand in the operation is converted into a 32 bit number. The result is converted back to a JavaScript number.
| Operator | Description | Example | Same as | Result | Decimal |
|---|---|---|---|---|---|
| & | AND | x = 5 & 1 | 0101 & 0001 | 0001 | 1 |
| | | OR | x = 5 | 1 | 0101 | 0001 | 0101 | 5 |
| ~ | NOT | x = ~ 5 | ~0101 | 1010 | 10 |
| ^ | XOR | x = 5 ^ 1 | 0101 ^ 0001 | 0100 | 4 |
| << | Left shift | x = 5 << 1 | 0101 << 1 | 1010 | 10 |
| >> | Right shift | x = 5 >> 1 | 0101 >> 1 | 0010 | 2 |
| The examples above uses 4 bits unsigned examples. But JavaScript uses 32-bit signed numbers. Because of this, in JavaScript, ~ 5 will not return 10. It will return -6. ~00000000000000000000000000000101 will return<PHONE_NUMBER>1111111111111111111010 |
The typeof Operator
The typeof operator returns the type of a variable, object, function or expression:
Example
typeof "John"
// Returns string
typeof 3.14
// Returns number
typeof NaN
// Returns number
typeof false
// Returns boolean
typeof [1, 2, 3, 4] // Returns object
typeof {name:'John', age:34}
// Returns object
typeof new Date()
// Returns object
typeof function () {} // Returns function
typeof myCar
// Returns undefined (if myCar is not declared)
typeof null
// Returns object
Try it Yourself »
Please observe:
- The data type of NaN is number
- The data type of an array is object
- The data type of a date is object
- The data type of null is object
- The data type of an undefined variable is undefined
| You cannot use typeof to define if a JavaScript object is an array (or a date). |
The delete Operator
The delete operator deletes a property from an object:
Example
var person = {firstName:"John", lastName:"Doe", age:50, eyeColor:"blue"};
delete person.age; // or delete person["age"];
Try it Yourself »
The delete operator deletes both the value of the property and the property itself.
After deletion, the property cannot be used before it is added back again.
The delete operator is designed to be used on object properties. It has no effect on variables or functions.
Note: The delete operator should not be used on predefined JavaScript object properties. It can crash your application.
The in Operator
The in operator returns true if the specified property is in the specified object, otherwise false:
Example
// Arrays
var cars = ["Saab", "Volvo", "BMW"];
"Saab" in cars //
Returns false (specify the index number instead of value)
0 in cars //
Returns true
1 in cars //
Returns true
4 in cars //
Returns false (does not exist)
"length" in cars //
Returns true (length is an Array property)
// Objects
var person = {firstName:"John", lastName:"Doe", age:50};
"firstName" in
person // Returns true
"age" in person
// Returns true
// Predefined objects
"PI" in Math
// Returns true
"NaN" in Number //
Returns true
"length" in String // Returns true
Try it Yourself »
The instanceof Operator
The instanceof operator returns true if the specified object is an instance of the specified object:
Example
var cars = ["Saab", "Volvo", "BMW"];
cars instanceof Array;
// Returns true
cars instanceof Object; // Returns true
cars instanceof String;
// Returns false
cars instanceof Number; // Returns false
Try it Yourself »
The void Operator
The void operator evaluates an expression and returns undefined. This operator is often used to obtain the undefined primitive value, using "void(0)" (useful when evaluating an expression without using the return value).
Example

Coldplay's new song honours Scott Hutchison after tragic death
Coldplay’s new track Champion Of The World pays tribute to Scott Hutchison after his tragic death.
The band are honouring the Frightened Rabbit frontman for his birthday (20 November).
The musician, who inspired Coldplay frontman Chris Martin with his track Los Angeles Be Kind, sadly took his own life back in May 2018 after struggling with depression and anxiety.
Chris has explained that the new song from the band’s upcoming album Everyday Life is inspired by the track, which Scott wrote as part of his solo music project Owl John.
‘Scott had a song called Los Angeles Be Kind, which I love,’ Chris said. ‘When I first heard it, I thought it was going to go one way – but it went another. Anyway Champion Of The World is the song that came from following the other path, and that’s why Scott is a co-writer on this song.

‘Today is also his birthday. So happy birthday Scott and thank you for your beautiful music, wherever you are.’
Meanwhile, Scott’s Frightened Rabbit bandmate Simon Liddell described the Coldplay track as ‘a beautiful song’.
‘Hopefully through Coldplay, more people will discover the Owl John, and the Frightened Rabbit back catalogue,’ he added to NME. ‘Earlier this year, Coldplay got in touch again, having recorded a sister version of the song.
‘The Coldplay camp have been amazing – keeping us in the loop on the track’s progress at each stage. We’re grateful to have played a part in that.’
Scott was confirmed dead back in May last year at the age of 36 after going missing.
In his final tweets, he said: ‘Be so good to everyone you love. It’s not a given. I’m so annoyed that it’s not. I didn’t live by that standard and it kills me. Please, hug your loved ones.’
At 4.09pm, he wrote: ‘I’m away now. Thanks.’
Hutchison was celebrated for being open about his struggles with his mental health in his music, with the star talking about being ‘consumed by the negatives’ in an interview just weeks before his death.

--- layout: post title: JRun 2.3.3 installation problems (Win32) tags: [] status: publish type: post published: true meta: {} ---
One of our projects here at Nemas required the use of servlets. In order to have a play with servlets before the project got under way in earnest, I decided to install JRun. Once the installation was completed I tested the installation and to my joy everything was working, or so I thought. For once I tried to execute a .cfm template I got an error. As it turned out all the mappings for .cfm has been re-mapped away from the Cold Fusion Application Server and mapped to the JRun server. Very annoying.
This document is now going to talk you through fixing this problem. First off you need to locate the rules.properties file, which is usually located in the <drive letter>:JRunjsm-defaultservicespropetiescfanywhere directory. Open this file up in your text editor of choice.
Now all you need to do is remove the following line:
*.cfm=com.livesoftware/cfanywhere.CFServlet
Save the file. In order for these changes to take effect you will need to stop and restart certain services. Go to the Control Panel and choose services. First stop the following services, then after all have been stopped, re-start them.
It is important that you stop the services through the Services icon. Stopping IIS through the MMC will not bring about the necessary changes.

A library for safe functional programming in JavaScript, with
first-class support for TypeScript and Flow, that has Maybe
and Result
types,supporting both a functional style and a more traditional method-call
style.
Add True Myth to your dependencies:
with Yarn:
yarn add true-myth
with npm:
npm install true-myth
Each of CommonJS, AMD, and ES modules are shipped, so you may reference them
directly from their installation in the node_modules
directory. (This may be
helpful for using the library in different contexts, with the ES modules being
supplied especially so you can do tree-shaking with e.g. Rollup.)

Flow should just work. You can simply use the module as a normal ES6-style module import, whether working in Node or using something like Webpack.
For TypeScript, whether using Webpack or Ember CLI or something else for your
bundling, you will be able to import the root module directly but will not be
able to import the more useful modules. To do so, you'll need to add this to
your tsconfig.json
:
{
"compilerOptions": {
"paths": {
"true-myth/*": ["node_modules/true-myth/dist/types/src/*"],
}
}
}
Before this hits 1.0, I will do:
[x] Maybe
bind
, chain
, etc.[x] Result
[x] All the exports
[x] Ember CLI integration
If you think another type should be in this list, please open an issue!
If you're unsure of why you would want to use the library, you might jump down to What is this for?.
These examples don't cover every corner of the API; it's just here to show you what a few of the functions are like. Full API documentation is available! You can also view the source if you prefer.
Result
with a functional styleimport { Result, map, toString } from 'true-myth/result';
function fallibleCheck(isValid: boolean): Result<string, { reason: string }> {
return isValid ? ok('all fine here') : err({ reason: 'was not valid' });
}
const describe = s => 'The outcome was: ' + s;
const wentFine = fallibleCheck(true);
const mappedFine = map(describe, wentFine);
console.log(toString(mappedFine)); // "Ok(The outcome was: all fine here)"
const notGreat = fallibleCheck(false);
const mappedBad = map(describe, notGreat);
console.log(toString(mappedBad)); // "Err({ reason: 'was not valid' })"
Maybe
with the method styleimport { Maybe, Just, Nothing } from 'true-myth/maybe';
function safeLength(mightBeAString: Maybe<string>): Maybe<number> {
return mightBeAString.map(s => s.length);
}
const justAString = new Just('a string');
const nothingHere = new Nothing<string>();
console.log(safeLength(justAString).toString()); // Just(8)
console.log(safeLength(nothingHere).toString()); // Nothing
Maybe
You can use Maybe.of
to construct a Maybe
from any value. It will return a
Nothing
if the passed type is null
or undefined
, or a Just
otherwise.
import { of as maybeOf, Maybe } from 'true-myth/maybe';
function acceptsANullOhNo(value: number | null): Maybe<string> {
const maybeNumber = maybeOf(value);
return mapOr("0", n => n.toString(), maybeNumber);
}
Helpers are supplied to allow you to get at the values wrapped in the type:
import { ok, unsafelyUnwrap } from 'true-myth/result';
const theAnswer = ok(42);
const theAnwerValue = unsafelyUnwrap(theAnswer);
However, as its name makes explicit unsafelyUnwrap
is not a safe operation; if
the item being unwrapped is an Err
, this will throw an Error
. Instead, you
can use one of the safe unwrap methods:
import { ok, unwrapOr } from 'true-myth/result';
const theAnswer = ok(42);
const theAnswerValue = unwrapOr(0, theAnswer);
How do you represent the concept of not having anything, programmatically? As a
language, JavaScript uses null
to represent this concept; if you have a
variable myNumber
to store numbers, you might assign the value null
when you
don't have any number at all. If you have a variable myString
, you might set
myString = null;
when you don't have a string.
Some JavaScript programmers use undefined
in place of null
or in addition to
null
, so rather than setting a value to null
they might just set let
myString;
or even let myString = undefined;
.
Every language needs a way to express the concept of nothing, but null
and
undefined
are a curse. Their presence in JavaScript (and in many other
languages) introduce a host of problems, because they are not a particularly
safe way to represent the concept. Say, for a moment, that you have a function
that takes an integer as a parameter:
let myNumber = undefined;
function myFuncThatTakesAnInteger(anInteger) {
return anInteger.toString();
}
myFuncThatTakesAnInteger(myNumber); // TypeError: anInteger is undefined
When the function tries to convert the integer to a string, the function blows
up because it was written with the assumption that the parameter being passed in
(a) is defined and (b) has a toString
method. Neither of these assumptions are
true when anInteger
is null
or undefined
. This leads JavaScript
programmers to program defensively, with if (!anInteger) return;
style guard
blocks at the top of their functions. This leads to harder-to-read code, and
what's more, it doesn't actually solve the root problem. You could imagine
this situation playing itself out in a million different ways: arguments to
functions go missing. Values on objects turn out not to exist. Arrays are absent
instead of merely empty.
The result is a steady stream not merely of programming frustrations, but of errors. The program does not function as the programmer intends. That means stuff doesn't work correctly for the user of the software. Imagine a hammer where the head just slips off every so often, in ways you could compensate for but which makes it that much harder to just get the nail into the wood.
That's what null
and undefined
are. You can program around them. But
defensive programming is gross. You write a lot of things like this:
function isNil(thingToCheck) {
return thingToCheck === undefined || thingToCheck === null;
}
function doAThing(withAString) {
if (isNil(withAString)) {
withAString = 'some default value';
}
console.log(withAString.length);
}
If you forget that check, or simply assume, "Look, I'll never call this
without including the argument," eventually you or someone else will get it
wrong. Usually somewhere far away from the actual invocation of doAThing
, so
that it's not obvious why that value ended up being null
there.
TypeScript and Flow take us a big step in that direction, so long as our type
annotations are good enough. (Use of any
will leave us sad, though.) We can
specify that type may be present, using the maybe/optional annotation.
This at least helps keep us honest. But we still end up writing a ton of
repeated boilerplate to deal with this problem. Rather than just handling it
once and being done with it, we play a never-ending game of whack-a-mole. We
must be constantly vigilant and proactive so that our users don't get into
broken error states.
Maybe
and Result
are our escape hatch from all this madness.
We reach for libraries precisely so we can solve real business problems
while letting lower-level concerns live in the "solved problems" category. True
Myth, borrowing ideas from many other languages and libraries, aims to put
code written to defend against null
/undefined
problems in that "solved
problems" category.
Maybe
and Result
solve this problem once, and in a principled way,
instead of in an ad-hoc way throughout your codebase, by putting the value
into a container which is guaranteed to be safe to act upon, regardless of
whether there's something inside it or not.
These containers let us write functions with actually safe assumptions about parameter values by extracting the question, "Does this variable contain a valid value?" to API boundaries, rather than needing to ask that question at the head of every. single. function.
What is this sorcery?
It turns out you probably already have a good idea of how this works, if you've spent much time writing JavaScript, because this is exactly how arrays work.
Imagine, for a moment, that you have a variable myArray
and you want to map
over it and print out every value to the console. You instantiate it as an empty
array and then forget to load it up with values before mapping over it:
let myArray = [];
// oops, I meant to load up the variable with an array, but I forgot!
myArray.forEach(n => console.log(n)); // <nothing prints to the screen>
Even though this doesn't print anything to the screen, it doesn't unexpectedly blow up, either. In other words, it represents the concept of having nothing "inside the box" in a safe manner. By contrast, an integer has no such safe box around it. What if you could multiply an integer by two, and if your variable was "empty" for one reason or another, it wouldn't blow up?
let myInteger = undefined;
myInteger * 3; // 😢
Let's try that again, but this time let's put the actual value in a container and give ourselves safe access methods:
import * as Maybe from 'true-myth/maybe';
let myInteger = Maybe.of(undefined);
myInteger.map(x => x * 3); // Nothing
We received Nothing
back as our value, which isn't particularly useful, but it
also didn't halt our program in its tracks!
Result
is similar to Maybe
, except it packages up the result of an operation
(like a network request) whether it's a success (an Ok
) or a failure (an
Err
) and lets us unwrap the package at our leisure. Whether you get back a 200
or a 401 for your HTTP request, you can pass the box around the same either way;
the methods and properties the container has are not dependent upon whether
there is shiny new data or a big red error inside.
Best of all, when you use these with libraries like TypeScript or Flow, you can
lean on their type systems to check aggressively for null
and undefined
, and
actually eliminate those from your codebase by replacing anywhere you would
have used them with Maybe
.
Likewise, you can replace functions which take polymorphic arguments or have
polymorphic return values in order to try to handle scenarios where something
may be a success or an error with functions using Result
.
Any place you try to treat them as just the underlying value rather than the container, the type systems will complain, of course. And you'll also get help from smart editors with suggestions about what kinds of values (including functions) you need to interact with any given helper or method, since the type definitions are supplied.
By leaning on TypeScript or Flow to handle the checking, we also get all these benefits with no runtime overhead other than the cost of constructing the actual container objects (which is to say: very low!).
The design aims for True Myth are:
In practice, that means:
You can construct the variant types in the traditional JavaScript way or with a pure function:
import { Just, just, Nothing, nothing } from 'true-myth/maybe';
const classicalJust = new Just('value');
const classicalNothing = new Nothing();
const functionalJust = just('value');
const functionalNothing = nothing();
Similarly, you can use methods or pure functions:
import { ok, map } from 'true-myth/result';
const numberResult = ok(42);
const ok84 = numberResult.map(x => x * 2);
const ok21 = map(x => x / 2, numberResult);
As this second example suggests, the aim has been to support the most idiomatic approach for each style. This means that yes, you might find it a bit confusing if you're actively switching between the two of them. (Why would you do that?!?)
Using the library with TypeScript or Flow will just work and will provide
you with considerable safety out of the box. Using it with JavaScript will
work just fine, but there is no runtime checking, and you're responsible to
make sure you don't unwrap()
a Maybe
without checking that it's safe to
do so.
Since this is a TypeScript- and Flow-first library, we intentionally leave out any runtime type checking. As such, you should make use of the type systems if you want the benefits of the system. Many of the functions simply assume that the types are checked, and will error if you pass in items of the wrong type.
For example, if you pass a non-Maybe
instance to many functions, they will
simply fail – even the basic helpers like isJust
and isNothing
. These
assumptions have been made precisely because this is a TypeScript- and
Flow-first library. (See the discussion below comparing True Myth to
Folktale and Sanctuary if you aren't using TypeScript or Flow and need
runtime checking.)
The overarching themes are flexibility and approachability.
The hope is that a team just picking up these ideas for the first time can use them without adapting their whole style to a "traditional" functional programming approach, but a team comfortable with functional idioms will find themselves at home with the style of data-last pure functions. (For a brief discussion of why you want the data last in a functional style, see this blog post.)
(As a closely related note: True Myth does not currently supply curried variants of the functions. There are a lot of good options out there for that; both lodash and Ramda have tools for currying existing function definitions. It also profoundly complicates writing the type signatures for these functions, since neither TypeScript nor Flow can easily represent auto- curried functions – unsurprisingly, given they're uncommon in JavaScript. Using Ramda or lodash to get curried versions of the functions may be a huge win for you in your codebase, though!)
One important note: True Myth does not attempt to deeply-clone the wrapped values when performing operations on them. Instead, the library assumes that you will not mutate those objects in place. (Doing more than this would require taking on a dependency on e.g. lodash). If you violate that constraint, you can and will see surprising outcomes. Accordingly, you should take care not to mutate reference types, or to use deep cloning yourself when e.g. mapping over reference types.
import { just, map, unsafelyUnwrap } from 'true-myth/maybe';
const anObjectToWrap = { desc: ['this', ' ', 'is a string'], val: 42 };
const wrapped = just(anObjectToWrap);
const updated = map(obj => ({...obj, val: 92 }), wrapped);
console.log(unsafelyUnwrap(updated).val); // 92
// Now mutate the original
anObjectToWrap.desc.push('.');
// And… 😱 we've mutated the new one, too:
console.log(unsafelyUnwrap(updated).desc); // ["this", " ", "is a string", "."]
In other words: you must use other tools along with True Myth if you're going
to mutate objects you're wrapping in Maybe
or Result
.
True Myth will work quite nicely with lodash, Ramda, Immutable-JS, etc., so you can use whatever tools you like to handle this problem.
Maybe
The existing options in this space include Option
, Optional
, and Maybe
.
You could also point to "nullable," but that actually means the opposite of
what we're doing here – these represent types which can not be nullable!
Option
implies a choice between several different options; in this case
that's not really what's going on. It's also not really a great word for the
type in the sense that it's weird to read aloud: "an Option string" doesn't make
any sense in English.
Optional
is much better than Option
. The semantics are much more accurate,
in that it captures that the thing is allowed to be absent. It's also the nicest
grammatically: "an Optional string". On the other hand, it's also the longest.
Maybe
seems to be the best type name semantically: we're modeling something
which may be there – or may not be there! Grammatically, it's comparable to
"optional": "a Maybe string" isn't great – but "maybe a string" is the most
natural accurate way to answer the question, "What's in this field?" It's also
the shortest!
Optional
or Maybe
are both good names; Maybe
just seemed slightly better.
Maybe
variants: Just
and Nothing
Similar consideration was given to the names of the type variants. Options for
the "present" type in other libraries are Some
and Just
. Options for the
"absent" type are None
or Nothing
.
Just
?Both Just
and Some
are reasonable choices for this, and both have things to
recommend them semantically:
Given that "just a number" works (even if it's strictly a little less nice
than "some number") and that "just 12" works but "some 12" doesn't, Just
seems
to be a slightly better option.
Nothing
?Given the choice between None
and Nothing
, the consideration just came down
to the most natural language choice. "What's here? Nothing!" makes sense,
while "What's here? None" does not. None
also implies that there might be
more than one of the items. It's entirely unnatural to say "There is none of a
number here"; you'd normally say "there is no number here" or "there is nothing
here" instead. So Nothing
it is!
Result
In some languages and libraries, a more general type named Either
is used
instead of the more specific Result
name. The two are equivalent in
functionality – both provide two variants, each of which wraps a value. In the
Either
implementations, those are usually named Left
and Right
. In the
Result
implementations (both here and in other libraries and languages), they
are named Ok
and Err
.
The main difference between Either
and Result
is precisely that question of
generality. Either
can meaningfully capture any scenario where there are two
possible values resulting from a given function application, or applicable as
arguments to a function. Result
only captures the idea of something
succeeding or failing. In that sense, Either
might seem to be better: it can
capture what Result
captures (traditionally with Left
being the error case
and Right
being the success, or right, case), and many more besides.
However, in practice, the idea of a result is far and away the most common case
for using an Either
, and it's also the easiest to explain. (An Either
implementation would also be valuable, though, and it might be a later addition
to the library.)
Result
variants: Ok
and Err
Given a "result" type, we need to be able to express the idea of "success" and
"failure." The most obvious names here would be Success
and Failure
. Those
are actually really good names with a single problem: they're long. Needing to
write success(12)
or failure({ oh: 'no' })
is a lot to write over and over
again. Especially when there some options which also work well: Ok
and
Err
.
Both Ok
and Err
could be written out long-form: Okay
and Error
. But in
this case, the longer names don't add any particular clarity; they require more
typing; and the Error
case also overloads the existing name of the base
exception type in JavaScript. So: Ok
and Err
it is.
The design of True Myth draws heavily on prior art; essentially nothing of this
is original – perhaps excepting the choice to make Maybe.of
handle null
and undefined
in constructing the types. In particular, however, True Myth
draws particular inspiration from:
Option
and Result
types and their
associated methodsMaybe
and Result
implementationsMaybe
and Result
types and their
associated functionsThere are other great functional programming libraries out there... so why not just use one of them?
Note that much of the content between these sections is the same; it's presented as is so you can simply read the section appropriate to the library you're comparing it with.
Folktale has an API a lot like this one, as you'll see when perusing the docs. However, there are two main reasons you might prefer True Myth to Folktale:
True Myth is TypeScript-first and Flow-first, which means that it assumes you are using TypeScript or Flow if you're aiming for rigorous type safety.
By contrast, Folktale is a JavaScript-first library, with runtime checking built in for its types. Folktale's TypeScript support is in-progress, but will remain secondary until a TypeScript rewrite of the whole Folktale library lands... eventually.
There's value in both of these approaches, so True Myth aims to take advantage of the compilers and play in a no-runtime-cost space.
If you want a JS-focused (rather than TS- or Flow-focused) library which will help you be safer without a compiler, you should definitely pick Folktale over True Myth. If you've already using TS or Flow, True Myth is a bit nicer of an experience.
True Myth aims to keep functional programming jargon to a minimum and to use TypeScript and Flow type notation throughout its docs as well as in its implementation.
Folktale is aimed squarely at people who are already pretty comfortable with the world of strongly-typed functional programming languages. This is particularly evident in the way its type signatures are written out (using the same basic notation you might see in e.g. Haskell), but it's also there in its heavy use of functional programming terminology throughout its docs.
Haskell-style types are quite nice, and functional programming jargon is very useful. However, they're also another hump to get over. Again: a tradeoff.
By opting for type notation that TS or Flow developers are already familiar with, and by focusing on what various functions do rather than the usual FP names for them, True Myth aims at people just coming up to speed on these ideas.
The big win for Folktale over True Myth is Fantasy Land compatibility.
True Myth's API aims to be more idiomatic as JavaScript/TypeScript, with a couple differences in particular worth calling out:
function naming convention: True Myth uses PascalCase for types and
camelCase for functions – so, new Just(5)
and just(5)
, whereas
FolkTale uses the capitals as function names for type constructors, i.e.
Just(5)
, and does not support new
.
ease of construction from nullable types: True Myth allows you to
construct Maybe
types from nullable types with Maybe.of
, because JS
is full of null
and undefined
, and allowing Maybe.of
to handle
them makes it easier to be sure you're always doing the right thing.
Folktale's Maybe.of
only allows the use of non-nullable types, and
requires you to use Maybe.fromNullable
instead. This isn't
unreasonable, but it dramatically decreases the convenience of
integration with existing JS codebases or interfacing with untyped JS
libraries.
Sanctuary has many of the same goals as True Myth, but is much more focused on the expectations and patterns you'd see in Haskell or PureScript or similar languages. Its API and True Myth's are much less similar than Folktale and True Myth's are, as a result – the underlying details are often similar, but the names are nearly all different. A few of the major contrasts:
True Myth is TypeScript-first and Flow-first, which means that it assumes you are using TypeScript or Flow if you're aiming for rigorous type safety.
By contrast, Sanctuary is a JavaScript-first library, with runtime checking built in for its types. Sanctuary's TypeScript support is in progress, but will for the foreseeable future remain add-on rather than first-class. (Sanctuary does allow you to create a version of the module without the runtime checking, but it requires you to do this yourself.)
There's value in both of these approaches, so True Myth aims to take advantage of the compilers and play in a no-runtime-cost space.
If you want a JS-focused (rather than TS- or Flow-focused) library which will help you be safer without a compiler, you should definitely pick Sanctuary over True Myth. If you've already using TS or Flow, True Myth is a bit nicer of an experience.
True Myth aims to keep functional programming jargon to a minimum and to use TypeScript and Flow type notation throughout its docs as well as in its implementation.
Sanctuary is aimed squarely at people who are already extremely comfortable the world of strongly-typed, pure functional programming languages. This is particularly evident in the way its type signatures are written out (using the same notation you would see in Haskell or PureScript), but it's also present in Sanctuary's heavy use of functional programming terminology throughout its docs.
Haskell- and Purescript-style types are quite nice, and the functional programming jargon is very useful. However, they're also another hump to get over. Again: a tradeoff.
By opting for type notation that TS or Flow developers are already familiar with, and by focusing on what various functions do rather than the usual FP names for them, True Myth aims at people just coming up to speed on these ideas.
The big win for Sanctuary over True Myth is Fantasy Land compatibility, or familiarity if coming from a language like Haskell or PureScript.
True Myth's API aims to be more idiomatic as JavaScript/TypeScript, with a
one difference in particular worth calling out: the function naming
convention. True Myth uses PascalCase for types and camelCase for
functions – so, new Just(5)
and just(5)
, whereas Sanctuary uses the
capitals as function names for type constructors, i.e. S.Just(5)
, and does
not support new
.
Sanctuary also aims to provide a much larger suite of functions, more like Ramda but with Haskell- or PureScript-inspired type safety and sophistication. True Myth intentionally punts on those concerns, assuming that most consumers are already using a library like Lodash or Ramda and aiming to be easy to integrate with those instead.
Migrating from Folktale should be very straightforward: many of the names are the same, and the behavior of many of the functions is as well.

For slightly quirky historical reasons, libraries which borrow ideas from typed functional programming in JavaScript often use names related to the phrase "fantasy land" – especially Fantasy Land itself and Folktale.
"True Myth" leans on that history (and serves, hopefully, as a respectful nod to Folktale in particular, as both Folktale and Sanctuary are huge inspirations for this library), and borrows an idea from J.R.R. Tolkien and C.S. Lewis: what if all myths appeal to us because they point ultimately at something true – and what if some story with the structure of a myth were true in history? It's a beautiful idea, and the name of this library was picked as an homage to it.
