class ImagingPath(raytracing.matrixgroup.MatrixGroup) |
| |
ImagingPath(elements=[], label='')
ImagingPath: the main class of the module, allowing
the combination of Matrix() or MatrixGroup() to be used
as an imaging group with an object at the beginning.
Usage is to create the ImagingPath(), then append() elements
and display(). You may change objectHeight, fanAngle, fanNumber
and rayNumber. |
| |
- Method resolution order:
- ImagingPath
- raytracing.matrixgroup.MatrixGroup
- raytracing.matrix.Matrix
- builtins.object
Methods defined here:
- __init__(self, elements=[], label='')
- Initialize self. See help(type(self)) for accurate signature.
- apertureStop(self)
- The aperture in the system that limits the cone of angles
originating from zero height at the object plane.
Returns the position and diameter of the aperture stop
Strategy: we take a ray height and divide by real aperture
diameter at that position. Some elements may have a finite length
(e.g., Space() or ThickLens()), so we always calculate the ratio
before propagating inside the element and after having propoagated
through the element. The position where the absolute value of the
ratio is maximum is the aperture stop.
If there are no elements of finite diameter (i.e. all
optical elements are infinite in diameters), then
there is no aperture stop in the system and the size
of the aperture stop is infinite.
- axialRays(self, y)
- Synonym of marginal rays
- chiefRay(self, y)
- Chief ray for a height y (i.e., the ray that goes
through the center of the aperture stop)
The calculation is simple: obtain the transfer matrix
to the aperture stop, then we know that the input ray
(which we are looking for) will end at y=0 at the
aperture stop.
- createRayTracePlot(self, axes, limitObjectToFieldOfView=False, onlyChiefAndMarginalRays=False, removeBlockedRaysCompletely=False)
- Create a matplotlib plot to draw the rays and the elements.
Three optional parameters:
limitObjectToFieldOfView=False, to use the calculated field of view
instead of the objectHeight
onlyChiefAndMarginalRays=False, to only show principal rays
removeBlockedRaysCompletely=False to remove rays that are blocked.
- display(self, limitObjectToFieldOfView=False, onlyChiefAndMarginalRays=False, removeBlockedRaysCompletely=False, comments=None)
- Display the optical system and trace the rays. If comments are included
they will be displayed on a graph in the bottom half of the plot.
- drawEntrancePupil(self, z, axes)
- drawImages(self, axes)
- Draw all images (real and virtual) of the object defined by
objectPosition, objectHeight
- drawObject(self, axes)
- Draw the object as defined by objectPosition, objectHeight
- drawOpticalElements(self, z, axes)
- Deprecated. Use drawAt()
- drawRayTraces(self, axes, onlyChiefAndMarginalRays, removeBlockedRaysCompletely=True)
- Draw all ray traces corresponding to either
1. the group of rays defined by the user (fanAngle, fanNumber, rayNumber)
2. the principal rays (chief and marginal)
- drawStops(self, z, axes)
- AS and FS are drawn at 110% of the largest diameter
- entrancePupil(self)
- The entrance pupil is the image of the aperture stop
as seen from the object. To obtain this image, we simply
need to know the tranfer matrix to the aperture stop,
then find the "backward" conjugate, which means finding
the position of the "image" (the entrance pupil) that would
lead to the "object" (aperture stop) at the end of the transfer
matrix. All the terminology is such that it assumes
the "object" is at the front and the "image" is at the back,
so we need to invert the magnification.
Returns the pupilPosition relative to input reference plane
(positive means to the right) and its diameter.
- fieldOfView(self)
- The field of view is the maximum object height
visible until its chief ray is blocked by the field stop
Strategy: take ray at various heights from object and
aim at center of pupil (chief ray from that point)
until ray is blocked. It is possible to have finite
diameter elements but still an infinite field of view
and therefore no Field stop.
- fieldStop(self)
- The field stop is the aperture that limits the image
size (or field of view)
Returns the position and diameter of the field stop.
Strategy: We want to find the exact height from the object
where it is blocked by an aperture (which will become the
field stop). We look for the point that separates the
"unblocked" ray from the "blocked" ray.
To do so, we take a ray at various heights starting at y=0
from object with a finite increment "dy" and aim
at center of pupil (i.e. chief ray from that height)
until ray is blocked. If it is not blocked, increase
dy and increase y by dy. When it is blocked, we turn
around and increase by only half the dy, then we continue
until it is unblocked, turn around, divide dy by 2, etc...
This rapidly converges to the position at which the ray
is blocked, which is the field stop half diameter. This
strategy is better than linearly going through object heights
because the precision can be very high without a long calculation
time.
It is possible to have finite diameter elements but
still an infinite field of view and therefore no Field stop.
In fact, if only a single element has a finite diameter,
there is no field stop (only an aperture stop). The limit
is arbitrarily set to maxHeight.
If there are no elements of finite diameter (i.e. all
optical elements are infinite in diameters), then there
is no field stop and no aperture stop in the system
and their sizes are infinite.
- imageSize(self)
- The image size is the object field of view
multiplied by magnification
- marginalRays(self, y=0)
- Marginal rays for a height y at object
(i.e., the rays that hit the upper and lower
edges of the aperture stop). In general, this could
be any height, not just y=0. However, we usually
only want y=0 which is implicitly called
"the marginal ray (of the system)", and both rays
will be symmetrically oriented on either side of the
optical axis.
The calculation is simple: obtain the transfer matrix
to the aperture stop, then we know that the input ray
(which we are looking for) will end at y= plus/minus diameter/2 at the
aperture stop. We return the largest angle first, for
convenience.
- rearrangeRayTraceForPlotting(self, rayList, removeBlockedRaysCompletely=True)
- save(self, filepath, limitObjectToFieldOfView=False, onlyChiefAndMarginalRays=False, removeBlockedRaysCompletely=False, comments=None)
Methods inherited from raytracing.matrixgroup.MatrixGroup:
- ImagingPath(self)
- LaserPath(self)
- append(self, matrix)
- Add an element at the end of the path
- drawAt(self, z, axes, showLabels=True)
- Draw each element of this group
- drawPointsOfInterest(self, z, axes)
- Labels of general points of interest are drawn below the
axis, at 25% of the largest diameter.
AS and FS are drawn at 110% of the largest diameter
- flipOrientation(self)
- Flip the orientation (forward-backward) of this group of elements.
Each element is also flipped individually.
- hasFiniteApertureDiameter(self)
- True if ImagingPath has at least one element of finite diameter
- largestDiameter(self)
- Largest finite diameter in all elements
- trace(self, inputRay)
- Trace the input ray from first element until after the last element
Returns a ray trace (i.e. [Ray()]) starting with inputRay, followed by the ray after
each element. If an element is composed of sub-elements, the ray will also be
traced in several steps.
- transferMatrices(self)
- The list of Matrix() that corresponds to the propagation through
this element (or group). For a Matrix(), it simply returns a list
with a single element [self].
For a MatrixGroup(), it returns the transferMatrices for
each individual element and appends them to a list for this group.
- transferMatrix(self, upTo=inf)
- The transfer matrix between front edge and distance=upTo
If "upTo" falls inside an element of finite length, then
it will request from that element a "partial" transfer matrix
for a fraction of the length. It is up to the Matrix() or
MatrixGroup() to define such partial transfer matrix when possible.
Quite simply, Space() defines a partial matrix as Space(d=upTo).
Methods inherited from raytracing.matrix.Matrix:
- __mul__(self, rightSide)
- Operator overloading allowing easy to read matrix multiplication
For instance, with M1 = Matrix() and M2 = Matrix(), one can write
M3 = M1*M2. With r = Ray(), one can apply the M1 transform to a ray
with r = M1*r
- __str__(self)
- String description that allows the use of print(Matrix())
- axesToDataScaling(self, axes)
- For drawing properly arrows and other things, sometimes
we need to draw along y in real space but in x in relative space
(i.e. relative to the width of the graph, not x coordinates).
There are transforms in matplotlib, but only between axes-display,
and data-display, not between data-axes. Here we obtain the scaling
so we can set arrow properties intelligently
- backFocalLength(self)
- The focal lengths measured from the back vertex.
This is the distance between the surface and the focal point.
When the principal plane is not at the surface (which is usually
the case in anything except a thin lens), the back and front focal
lengths will be different from effective focal lengths. The effective
focal lengths is always measured from the principal planes, but the
BFL and FFL are measured from the vertex.
If the matrix is the result of the product of several matrices,
we may not know where the front and back vertices are. In that case,
we return None (or undefined).
Currently, it is assumed the index is n=1 on either side and
both focal distances are the same.
- backwardConjugate(self)
- With an image at the back edge of the element,
where is the object ? Distance before the element by
which a ray must travel to reach the conjugate plane at
the back of the element. A positive distance means the
object is "distance" in front of the element (or to the
left, or before).
M2 = M1*Space(distance)
# M2.isImaging == True
- displayHalfHeight(self)
- A reasonable height for display purposes for
an element, whether it is infinite or not.
If the element is infinite, currently the half-height
will be '4'. If not, it is the apertureDiameter/2.
- drawAperture(self, z, axes)
- Draw the aperture size for this element. Any element may
have a finite aperture size, so this function is general for all elements.
- drawCardinalPoints(self, z, axes)
- Draw the focal points of a thin lens as black dots
- drawLabels(self, z, axes)
- Draw element labels on plot with starting edge at 'z'.
Labels are drawn 50% above the display height
- drawPrincipalPlanes(self, z, axes)
- Draw the principal planes
- drawVertices(self, z, axes)
- Draw vertices of the system
- effectiveFocalLengths(self)
- The effective focal lengths calculated from the power (C)
of the matrix.
Currently, it is assumed the index is n=1 on either side and
both focal lengths are the same.
- focalDistances(self)
- Synonym of effectiveFocalLengths()
- focusPositions(self, z)
- Positions of both focal points on either side of the element.
Currently, it is assumed the index is n=1 on either side and both focal
distances are the same.
- forwardConjugate(self)
- With an object at the front edge of the element, where
is the image? Distance after the element by which a ray
must travel to reach the conjugate plane of the front of
the element. A positive distance means the image is "distance"
beyond the back of the element (or to the right, or after).
M2 = Space(distance)*M1
# M2.isImaging == True
- frontFocalLength(self)
- The focal lengths measured from the front vertex.
This is the distance between the surface and the focal point.
When the principal plane is not at the surface (which is usually
the case in anything except a thin lens), the back and front focal
lengths will be different from effective focal lengths. The effective
focal lengths is always measured from the principal planes, but the
BFL and FFL are measured from the vertices.
If the matrix is the result of the product of several matrices,
we may not know where the front and back vertices are. In that case,
we return None (or undefined).
Currently, it is assumed the index is n=1 on either side and
both focal distances are the same.
- magnification(self)
- mul_beam(self, rightSideBeam)
- Multiplication of a coherent beam with complex radius
of curvature q by a matrix.
- mul_matrix(self, rightSideMatrix)
- Multiplication of two matrices. Total length of the
elements is calculated. Apertures are lost. We compute
the first and last vertices.
- mul_ray(self, rightSideRay)
- Multiplication of a ray by a matrix. New position of
ray is updated by the physical length of the matrix.
If the ray is beyond the aperture diameter it is labelled
as "isBlocked = True" but can still propagate.
- pointsOfInterest(self, z)
- Any points of interest for this matrix (focal points,
principal planes etc...)
- principalPlanePositions(self, z)
- Positions of the input and output principal planes.
Currently, it is assumed the index is n=1 on either side.
- traceMany(self, inputRays)
- Trace each ray from a list from front edge of element to
the back edge.
Returns a list of ray traces for each input ray.
See trace().
Data descriptors inherited from raytracing.matrix.Matrix:
- __dict__
- dictionary for instance variables (if defined)
- __weakref__
- list of weak references to the object (if defined)
- determinant
- hasPower
- isImaging
- If B=0, then the matrix is from a conjugate plane to another
(i.e. object at the front edge and image at the back edge).
In this case, A = transverse magnification, D = angular magnification
As usual, C = -1/f (always).

math::bignum - Arbitrary precision integer numbers
The bignum package provides arbitrary precision integer math (also known as "big numbers") capabilities to the Tcl language. Big numbers are internally represented at Tcl lists: this package provides a set of procedures operating against the internal representation in order to:
perform math operations
convert bignums from the internal representation to a string in the desired radix and vice versa.
But the two constants "0" and "1" are automatically converted to the internal representation, in order to easily compare a number to zero, or increment a big number.
The bignum interface is opaque, so operations on bignums that are not returned by procedures in this package (but created by hand) may lead to unspecified behaviours. It's safe to treat bignums as pure values, so there is no need to free a bignum, or to duplicate it via a special operation.
This section shows some simple example. This library being just a way to perform math operations, examples may be the simplest way to learn how to work with it. Consult the API section of this man page for information about individual procedures.
package require math::bignum # Multiplication of two bignums set a [::math::bignum::fromstr<PHONE_NUMBER>1111] set b [::math::bignum::fromstr<PHONE_NUMBER>0000] set c [::math::bignum::mul $a $b] puts [::math::bignum::tostr $c] ; # => will output<PHONE_NUMBER>604953086420000000 set c [::math::bignum::sqrt $c] puts [::math::bignum::tostr $c] ; # => will output<PHONE_NUMBER>7777 # From/To string conversion in different radix set a [::math::bignum::fromstr<PHONE_NUMBER>010111001001111010111 2] puts [::math::bignum::tostr $a 16] ; # => will output 62ab93d7 # Factorial example proc fact n { # fromstr is not needed for 0 and 1 set z 1 for {set i 2} {$i <= $n} {incr i} { set z [::math::bignum::mul $z [::math::bignum::fromstr $i]] } return $z } puts [::math::bignum::tostr [fact 100]]
Convert string into a bignum. If radix is omitted or zero, the string is interpreted in hex if prefixed with 0x, in octal if prefixed with ox, in binary if it's pefixed with bx, as a number in radix 10 otherwise. If instead the radix argument is specified in the range 2-36, the string is interpreted in the given radix. Please note that this conversion is not needed for two constants : 0 and 1. (see the example)
Convert bignum into a string representing the number in the specified radix. If radix is omitted, the default is 10.
Return the sign of the bignum. The procedure returns 0 if the number is positive, 1 if it's negative.
Return the absolute value of the bignum.
Compare the two bignums a and b, returning 0 if a == b, 1 if a > b, and -1 if a < b.
Return true if bignum value is zero, otherwise false is returned.
Return true if a < b, otherwise false is returned.
Return true if a <= b, otherwise false is returned.
Return true if a > b, otherwise false is returned.
Return true if a >= b, otherwise false is returned.
Return true if a == b, otherwise false is returned.
Return true if a != b, otherwise false is returned.
Return true if bignum is odd.
Return true if bignum is even.
Return the sum of the two bignums a and b.
Return the difference of the two bignums a and b.
Return the product of the two bignums a and b. The implementation uses Karatsuba multiplication if both the numbers are bigger than a given threshold, otherwise the direct algorith is used.
Return a two-elements list containing as first element the quotient of the division between the two bignums a and b, and the remainder of the division as second element.
Return the quotient of the division between the two bignums a and b.
Return the remainder of the division between the two bignums a and b.
Return n modulo m. This operation is called modular reduction.
Return base raised to the exponent exp.
Return base raised to the exponent exp, modulo m. This function is often used in the field of cryptography.
Return the integer part of the square root of bignum
Return a random number of at most bits bits. The returned number is internally generated using Tcl's expr rand() function and is not suitable where an unguessable and cryptographically secure random number is needed.
Return the result of left shifting bignum's binary representation of bits positions on the left. This is equivalent to multiplying by 2^bits but much faster.
Return the result of right shifting bignum's binary representation of bits positions on the right. This is equivalent to dividing by 2^bits but much faster.
Return the result of doing a bitwise AND operation on a and b. The operation is restricted to positive numbers, including zero. When negative numbers are provided as arguments the result is undefined.
Return the result of doing a bitwise OR operation on a and b. The operation is restricted to positive numbers, including zero. When negative numbers are provided as arguments the result is undefined.
Return the result of doing a bitwise XOR operation on a and b. The operation is restricted to positive numbers, including zero. When negative numbers are provided as arguments the result is undefined.
Set the bit at bit position to 1 in the bignum stored in the variable bignumVar. Bit 0 is the least significant.
Set the bit at bit position to 0 in the bignum stored in the variable bignumVar. Bit 0 is the least significant.
Return true if the bit at the bit position of bignum is on, otherwise false is returned. If bit is out of range, it is considered as set to zero.
Return the number of bits needed to represent bignum in radix 2.
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category math :: bignum of the Tcllib Trackers. Please also report any ideas for enhancements you may have for either package and/or documentation.
When proposing code changes, please provide unified diffs, i.e the output of diff -u.

DUNE 1984 A film review by Timothy Voon Copyright 1997 Timothy Voon 2 :-) :-) for the Spice of Life
Directed by David Lynch Cast Francesca Annis, Leonardo Cimino, Brad Dourif, José Ferrer, Linda Hunt, Freddie Jones, Richard Jordan, Kyle McLachlan, Virginia Madsen, Silvana Mangano, Everett McGill, Kenneth McMillan, Jack Nance, Sian Phillips, Jürgen Prochnow, Patrick Stewart Paul Smith, Sting, Dean Stockwell, Max von Sydow, Sean Young. Based on a novel written by Frank Herbert
When one attempts to recreate a science fiction masterpiece, and a novel as thick as Dune, it had better be well done, or there will be cries of lynching or stoning from an angry mob. I cannot say that Dune is exceptionally well done, when a good second half of the novel is compressed into minutes of narration to help shorten the movie. So my after thought is that perhaps a mini-series may have done this Epic novel more justice than a feature length film.
One has to at least commend David Lynch for attempting a feat as difficult as Dune. Although the special effects are not wiz bang spectacular, he has managed to recreate the feel of the desert planet Arrakis (aka Dune), which is the taste of Spice itself. Spice is the most precious commodity in the universe. He who controls Spice controls the world. For with it space travel or jumping is made possible, and it is only found on one planet in the entire universe, on the desert planet of Dune. The political scene is of an Emperor who controls the Spice but is worried about the ascendancy of a rival House Atreides. To secure his throne, he pits one powerful House against another. Namely Atreides against Harkonnen, in order to weaken them, yet strengthen his own seat.
David Lynch best known for his dark, gothic, new age features like Twin Peaks, in some ways is ideal for a movie like Dune. After all, one needs a director to match the likes of the twisted yet brilliant mind of author Frank Herbert. A prime example of the darker side, is the homoerotic scene where a young man brings flowers in to the throne room of the raving mad Baron Harkonnen. The obese and disfigured Baron approaches the boy with a look of insatiable lust before ripping out his heart plug. As the boy is dying, the Baron bathes in his victim's blood before climaxing with an orgasm. The other scene of note is when an enemy of the Baron is made to suffer by being made to shamefully milk the antidote from a cat to counter the effects of a poison. Now if these scenes do not encompass the meaning of perversity, I'm not sure what does.
On a lighter and brighter note, less shadowed by the darker side of Herbert and Lynch. This movie captures and recreates the wonders of dry desert winds beating against frail human flesh; in a wilderness where water is as precious as blood. Here the protectors of Spice are giant Sand Worms which tower over the precious commodity like monolith Colossi. This is a world where Bene Gesserit priestesses mind bend and control the feeble minded, and the Fremen await the coming of a foretold Messiah to inflame their blood with long awaited freedom. This is the legacy of Dune.
Although Lynch has failed to recapture the immensity of the epic events that unfold in the novel, he has succeeded in recreating the unique flavour and feel of this most inspired of Herbert's works.

The River Exe forms an attractive stop on the western side of Lyme Bay.
Position 50°36.9'N, 03°25.4'W.
Beware of the strong ebb tide in the entrance channel, which, in a brisk wind from the south or SW can kick up a nasty chop.
River Exe - due to severe silting several years ago, an alternative buoyed channel was marked. Call Channel 12 for the latest situation as depths, drying heights and contours need to be checked. (August 2008)
There are many places to pick up a visitors' mooring in the river.
In addition, the small commercial dock at Exmouth has now been converted into a marina and there are pontoon berths in Turf Basin.
Night entry is not advised.

Berkeley DB: db_stat
db_stat
db_stat [-clmNt]
[-C Acfhlmo] [-d file] [-h home] [-M Ahlm]
Description
The db_stat utility displays statistics for Berkeley DB environments.
The options are as follows:
- -C
- Display internal information about the lock region.
(The output from this option is often both voluminous and meaningless,
and is intended only for debugging.)
- A
- Display all information.
- c
- Display lock conflict matrix.
- f
- Display lock and object free lists.
- l
- Display lockers within hash chains.
- m
- Display region memory information.
- o
- Display objects within hash chains.
- -c
- Display lock region statistics as described in lock_stat.
- -d
- Display database statistics for the specified database, as described
in db_open.
- -h
- Specify a home directory for the database.
- -l
- Display log region statistics as described in log_stat.
- -M
- Display internal information about the shared memory buffer pool.
(The output from this option is often both voluminous and meaningless,
and is intended only for debugging.)
- A
- Display all information.
- h
- Display buffers within hash chains.
- l
- Display buffers within LRU chains.
- m
- Display region memory information.
- -m
- Display shared memory buffer pool statistics as described in
memp_stat.
- -N
- Don't acquire shared region locks while accumulating the statistics.
This option is intended only for debugging corrupt regions and should not
be used under any other circumstances.
- -t
- Display transaction region statistics as described in
txn_stat.
Values smaller than 10 million are generally displayed without
any special notation.
Values larger than 10 million are normally displayed as M.
The db_stat utility attaches to one or more of the Berkeley DB shared memory
regions. In order to avoid region corruption, it should always be given
the chance to detach and exit gracefully. To cause db_stat to clean up
after itself and exit, send it an interrupt signal (SIGINT).
The db_stat utility exits 0 on success, and >0 if an error occurs.
Environment Variables
- DB_HOME
-
If the -h option is not specified and the environment variable
DB_HOME is set, it is used as the path of the database home, as described
in db_appinit.

asc & me
a guide to working with and being around me.
why are you reading this?
The chances are you and I currently, or are about to, spend some time together. Maybe we work together, are living together, or have somehow ended up in each other’s lives. This probably means that at some point you will notice some differences in the way I do things.
This is because I am autistic.
These differences are not inherently bad. Some cause me problems. Some I’m quite fond of. In any case, understanding them can help the time we spend together be easier for both of us. I’ve written this to help with that understanding.
This page will give you a little background on autism, explain why I might not seem autistic, and give you an idea of what you can do to make our experience together easier for both of us. In particular, there’s some info on how we can communicate better, some of the differences in the way my brain processes information, and why some of my needs might be different to yours. Clicking any point in these last three sections will reveal a short explanation, and where relevant an illustrative example from my life.
tl;dr
- I am a normal human being. autism is not a problem: it is a difference in how I experience the world.
- be direct. don’t assume I’ve understood anything conveyed through tone, context, or body language.
- be tolerant of my communication style. I form connections through sharing information.
- respect my personal space (I need lots). ask me before requiring my attention or energy.
- respect my need to control aspects of my environment.
- give me advance warning about changes in plan, especially when they require social contact.
- try not to interrupt me unnecessarily (but feel free to interrupt unwanted monologues).
- be conscious that noise that I have no control over is distressing for me.
- by masking I’m working hard to make you comfortable. please meet me in the middle!
a little background
I was diagnosed with Asperger’s syndrome1, now called Autistic Spectrum Condition2, at the age of 29. I have been autistic all my life and always will be. This is because autism is a neurodevelopmental condition that affects the way my brain processes information.
You might have heard autism described as a ‘‘spectrum’’.  There are many things we have in common – the traits that make us autistic – but we all experience these in different ways, in different combinations, and to different degrees of intensity. The things I’m sharing here describe my specific experience of autism.
Being autistic has caused me many challenges, and continues to do so, but there are also many things I like about being autistic. For example, I am good at abstract reasoning; I come up with unconventional solutions to problems; I quickly notice patterns and can quickly grasp how things work; I give my interests unrelenting focus; and I thrive on collecting information and understanding things.
but you don’t seem autistic
So I have been told. And so have many other autistic people. This is because of masking. In brief, we consciously suppress behaviours that come naturally to us (such as stimming and infodumping), and adopt behaviours that don’t come naturally (such as sustaining eye contact or making small talk). We do this to better fit into the neurotypical world. After a lifetime of masking to survive, many of us become very good at it. This is why I, and many other autistic people, often do not seem autistic.
It might seem like a compliment to tell us this, but it can be invalidating to hear. And the implication that there’s something desirable about seeming less autistic is hurtful: it suggests that there’s something fundamentally wrong with who we are.
Masking comes at a cost: it demands constant vigilance. At best this is exhausting, and at worst can lead to shutdown and burnout. It’s a little like living in a country where nobody speaks your native language. To communicate and survive, you must learn and use the local language, which requires constant attention and effort. Even after many years, you’ll probably always speak with an accent and misunderstand idioms. A few hours at a party, for a native speaker, might be a relaxing way to unwind, but by the end of the night you will probably be exhausted from the effort of simply communicating. Note: this doesn’t mean you can’t enjoy the party!
communication
Autism means I communicate differently from allistic3 people. Masking means I make an effort to suppress many of these differences, but I can’t do this all the time. And even when I do mask, there are things I can’t change. Being aware of these points can help us communicate better:
-
Be direct about what you want. If you hint at something I will probably miss it.
I'm not being rude.
If you say, ''that looks tasty'', and you mean, ''I would like to try some'', I will likely just hear ''that looks tasty'' and respond accordingly.
example
A manager at a previous job said something along the lines of, ''this really needs doing''. I told him, ''okay,'' and we left it at that. A couple of days later he asked me ''have you done [the thing]?'' and I, surprised, responded, ''no, you didn't ask me to!''
In retrospect, it's clear to me what he wanted — I can absolutely understand implicit and subtextual communication when given time to process. In the moment, however, parsing this sort of hidden intent is not easy and I will get it wrong much of the time. Had he said, ''Ben, I need you to do this,'' we would have avoided the misunderstanding.
-
Tell me how you're feeling. I won't pick it up from your tone.
This goes especially if you're annoyed or upset.
Once I know how you feel, I can be very empathetic, but I need some help getting there. I can often sense that something is wrong, but not understand what or why. In these situations, even if it's nothing to do with me it can be helpful to let me know, as otherwise I will be stuck trying to consciously figure out whether it's because of me. Counterintuitively, I can be very sarcastic myself, but can't always pick up when others are.
-
Be specific with questions, or ask follow-up questions.
I usually don't know how much information is appropriate.
If you ask a question, I may answer unhelpfully briefly. Or, I may give an unnecessarily long-winded answer. Please don't be annoyed! You can simply nudge me in the right direction with follow-up questions. Similarly, if I ask you a question, there's unlikely to be subtext — I probably just want a direct answer.
example
A former colleague asked me — ''what are your lunch plans?'' — to which I responded with my lunch plans and returned to work. Thankfully, they realised I had misunderstood what they meant and rephrased more directly: ''what I meant was, would you like to get lunch together?''
As it happened, I did want to get lunch together, and all was well. More often than not, however, my answer is taken as abrupt, rude, evasive, or unhelpful. As, in the moment, I am often not able to infer the true intent of a question, the easiest way to avoid this situation is to ask directly for the information you need.
-
Give me the benefit of the doubt and don't assume I'm being arrogant or condescending.
I tend to communicate in facts and information. I'm not trying to be a know-it-all.
I form social connections by exchanging information, rather than by making chit-chat or sharing emotions. Chances are, if I'm sharing info about something it's because I'm trying to engage with you, not because I'm trying to imply you don't understand.
example
Linguistics, phonology, and language genealogy have been recurring special interests of mine. In a group conversation, someone who had recently relocated to a new country mentioned an interesting feature of the country's language. I happened to know a little bit about analogues of this feature in a number of other languages and so I thought the group would like to know a little about it. I shared what I had learnt and gave a number of examples, but nobody really engaged. The conversation quickly moved on and from that point onwards people were unresponsive to my contributions.
In retrospect, this is because they were connecting over the person's experience and not the factual content. Whilst my contribution was well intentioned — I simply wanted to join in — it was received more like an unwelcome lecture than an attempt to connect. A little more understanding from both sides of our different communication styles would have avoided them feeling condescended and spoken down to, and avoided me feeling excluded and unwelcome.
-
If I start ''infodumping'' and you don't want to hear it, tell me!
If something I'm very interested in comes up in conversation, there's a strong chance I'll ''go off on one''.
This is a very common autistic trait. I manage to hold back a lot of the time but I'm not always aware I'm doing it. If you're not interested, please interrupt and just say. It's much better than you being bored and me feeling humiliated after realising I've subjected you to an unwanted monologue!
example
At a pub with a group of friends, someone asked me what I had been up to recently. I mentioned that I was working on AI and audio synthesis, and they said, ''oh that sounds interesting.'' I mistakenly took this as an invitation to explain more, and before I knew it I was in the middle of a big infodump. As I was speaking, I was having a great time. Infodumping feels fantastic, and I was completely oblivious to my friend's disinterest. But as I was wrapping up, another friend walked over and said, ''what's up, guys?'' to which the recipient of my infodump replied, ''Ben's just giving me a lecture.''
This is a pretty benign example — this is a friend who has known me long enough to accept this aspect of my personality. Even so, I was humiliated and he was bored. We could both have had a much better time if we'd simply had a mutual understanding that it was okay for him to let me know he was disinterested.
-
Don't expect eye contact from me, and don't pressure me to make it.
I am listening.
Eye contact is sometimes uncomfortable for me, and many autistic people I've spoken to. It's often easier for me to process what you're saying and to think about what I'm saying without it. I may or may not make eye contact, but if I'm not looking at you, I am almost definitely still listening!
executive functioning and sensory processing
Lots of evidence (see here, here, here, here, and here) shows that autistic brains work differently in a couple of key areas. In particular, we can struggle with executive functioning and sensory processing.
-
Be patient, and understand that I might not be able to do things as easily as other people
I'm probably not being lazy!
Autism shares many characteristics with ADHD, one of which is executive dysfunction. I can find it hard to plan, initiate, and switch tasks, and this often means I can't simply ''do'' things in the same way neurotypical people can. Please be patient!
-
Feel free to remind me of the big picture.
Autism means I can become very focused on details.
This can be incredibly useful, but it can also mean I lose sight of the big picture. Sometimes this is fine, but sometimes this causes a problem, especially when collaborating. If you think I've gotten lost in the details, it's okay to let me know.
example
Back in my days as a music producer, I met with another producer for a collaborative session. At some point he said, ''it would be cool if the sound could morph in to this other one.'' I thought that sounded like a great idea, and an interesting challenge. I opened up Max/MSP and started to put together a frequency-domain morphing algorithm. It proved to be a much bigger task than I had anticipated (how naïve I was) and I quickly became consumed by solving this problem, completely forgetting about the music we were making together. After an hour had passed, my collaborator excused himself and left.
Of course, in hindsight this makes me cringe. Clearly this wasn't the best use of our time, and clearly it's not entirely socially appropriate to ignore someone whilst fixating on a tangential task they have little interest in. But, this sort of thing happens frequently, and can be avoided by a little reminder to remember the big picture.
-
If I'm hyperfixating, leave me be unless it's causing problems.
Often I will become intensely focused on something like a topic, a task, or an idea.
From the outside this can look a little like obsession, but for me it's usually a good thing. It is often when I do things I'm proud of. Unless there's a good reason not to, it's probably best to leave me to it!
-
Try not to interrupt me when I'm focusing.
Because of executive dysfunction, it's very hard to get back on track after an interruption.
If you need my attention for something, please first consider whether it can wait until I'm not focused.
-
Be conscious of noise and when possible try to limit it around me.
You'll notice me wearing noise cancelling headphones a lot of the time.
This is because autistic brains tend to struggle to ''filter'' sensory input. For me, this is particularly challenging with sound. Quiet sounds are hugely distracting and loud sounds can be very distressing -- the sound of a door slamming or a plate smashing can ruin the rest of my day. Particular types of sound can also lead to surprisingly strong emotional responses, which might not make total sense from an outside perspective. Of course, sounds happen, and I'm not asking anyone to be silent around me, but keeping in mind that this affects me will help us have a better time around each other.
-
Don't read too much into the things I do with my hands.
Unless they're actively bothering you, it's probably best just to let me get on with it!
 When I'm alone this list is much longer. Lots of autistic people have a repertoire of these behaviours, called ''stims''. There are lots of theories as to why we do this, but ultimately they feel necessary and suppressing them is hard.
the bucket
The world can be very intense for autistic people. Sensory overload, social pressures, and unexpected change can all be very overwhelming. To understand this I find it’s helpful to imagine everyone as having a bucket. Throughout the day, stressful experiences can add little bits of water to the bucket. As the bucket fills up, it gets harder and harder to carry, and eventually becomes so heavy it may not even be possible to lift it. Or the bucket might get so full it overflows. Everyone has a bucket. Everyone’s bucket is different. Some are big, some are small. Some have big taps that open easily, whilst some have small taps that barely let the water escape. Autistic people tend to have small buckets, and this alone is difficult. But the big difference is that there are many things which don’t add water to most people’s buckets, but which add water to ours.
These points explain how my bucket gets filled up, and what happens when it gets too full:
-
Don't take it personally when I decline invitations.
Masking fills up my bucket.
I like to socialise, but the truth is I need to recover from almost every social occasion. If I turn down an invitation, it's likely because I need to think about how much space remains in my bucket.
-
Give me advance warnings about social situations and changes in plans.
New people and unexpected situations overwhelm me.
Adapting to change is hard, and socialising with new people is hard. If you can let me know ahead of time, I can prepare myself and keep my bucket empty, which can make things easier. The more information you can give about what to expect, the better.
-
Check how full my bucket is before expecting my engagement or attention.
And be understanding if I can't give it to you right now.
Perhaps you've had a hard day and need to vent, or perhaps you want my input or opinion or something. If my bucket is already full, giving you the engagement you want may be more than I'm capable of. However, communicating this without being rude is a big challenge, and if I'm already drained I may not be able to put on the necessary social performance — it's hard for me to navigate the social nuances of politely asking someone to leave me alone! To avoid this tricky situation, you can directly ask whether I'm currently able to engage with you.
-
Understand shutdowns.
Autistic shutdown is, essentially, what happens when our buckets get too full to carry.
For me this means I will likely have a very distant expression on my face, not be moving much, and be unlikely to talk. In this situation, I need a calm, quiet place to recover. Often I'm able to anticipate the shutdown and remove myself from the situation. Generally, if I seem blank, distant, or withdrawn, I probably need to empty my bucket, and simply need space. Don't take it personally! If you notice this happening, you can help me get away and avoid challenging sensory stimuli or social pressures. Don't pressure me to talk or do anything! I'll let you know when I'm ready to re-engage.
example
A recent shutdown occurred because I had spent three consecutive days away from home in the company of other people. Whilst they were all lovely people and I enjoyed their company (when my bucket was less full), eventually the social demands and unfamiliarity of the situation took their toll and led to a shutdown. Thankfully, the full shutdown only started when I made it home, but it meant I was unable to do much other than lie down for several hours. My partner was able to help me by ensuring my environment was calm and taking care of obligations like making food.
Shutdowns normally have a recovery period, during which I am particularly sensitive, and prone to having further shutdowns. Some of my other autistic traits may become more pronounced during this time, as I usually do not have the energy to effectively mask. This particular shutdown was no different, and I was forced to cancel a meeting and a social occasion the following day.
-
Rituals help me keep my bucket from filling up.
You might notice that I need certain things to be done in a particular way.
Similarly, there are certain objects I like to keep in a particular place, and certain things I'd prefer not to share. This predictability helps me deal with the unpredictable things in life. If it doesn't cause you any problems, we'll both have a better time if you just let me get on with it!
example
I am an absolute nightmare to cook with for two reasons.
Firstly, it is difficult for me to deviate from my learned way of doing things. You want to chop the onion differently to me? You organise your cooking space differently to me? That's going to be a struggle for me. If my bucket is relatively empty, I will probably suppress the urge to ask you to do it differently, but this act of masking will add to my bucket.
Secondly, cooking alone is a soothing, ritualistic activity for me. Cooking together is chaotic, intense, and fraught with subtle social challenges that continually add to my bucket. Sooner or later, my bucket will get too full to mask and you might find me suddenly intense or difficult to be around.
This is not to say I can't cook with people, or that it can't be enjoyable. When I've successfully cooked with other people, it has been because we agreed in advance who would take which tasks. This was done in such a way that allowed me to stick to my established ways of doing things, whilst others could do things as they wished.
…and the rest
Autism is hugely complex, and everyone’s experience of it is different. This page just lists some of the main aspects that might influence our relationship. If you want to know more, please do ask! I’m very happy to answer questions and talk. I’m also happy to point you to resources if you’d like to learn more about autism in general.
In any case, thank you for taking the time to read this. Making the effort to understand the autistic people in your life – and there are almost definitely more4! – can help make everyone’s lives better.

The following is a list of the class names used by jQuery UI. The classes are designed to create a visual consistency across an application and allow components to be themeable by jQuery UI ThemeRoller. The class names are split between ui.core.css and ui.theme.css, depending on whether styles are fixed and structural, or themeable (colors, fonts, backgrounds, etc) respectively.
.ui-helper-hidden
: Hides content visually and from assistive technologies, such as screen readers.
.ui-helper-hidden-accessible
: Hides content visually, but leaves it available to assistive technologies.
.ui-helper-reset
: A basic style reset for DOM nodes. Resets padding, margins, text-decoration, list-style, etc.
.ui-helper-clearfix
: Applies float wrapping properties to parent elements.
.ui-front

: Class to be applied to a priority-2 button in situations where button hierarchy is needed.
.ui-icon
: Base class to be applied to an icon element. Sets dimensions to a 16px square block, hides inner text, and sets background image to the "content" state sprite image. Note: ui-icon
class will be given a different sprite background image depending on its parent container. For example, a ui-icon
element within a ui-state-default
container will get colored according to the ui-state-default
's icon color.
After declaring a ui-icon
class, you can follow up with a second class describing the type of icon. Icon classes generally follow a syntax of .ui-icon-{icon type}-{icon sub description}-{direction}.
For example, a single triangle icon pointing to the right looks like this: .ui-icon-triangle-1-e
. ThemeRoller provides the full set of CSS framework icons in its preview column. Hover over them to see the class name.

--- title: Metrics keywords: fastai sidebar: home_sidebar summary: "Algorithm assessment metrics." ---
Recall@k is a standard information retrieval metric. For example, suppose that we computed recall@10 equal to 40% in our top-10 recommendation system. This means that 40% of the total number of the relevant items appear in the top-k results.
More formally we have:
$$Recall@k = \frac{\text{number of recommended items @k that are relevant}}{\text{total number of relevant items}}$$Arguments:
predictions = (5, 6, 32, 67, 1, 15, 7, 89, 10, 43)
targets = (15, 5, 44, 35, 67, 101, 7, 80, 43, 12)
assert recall_at_k(predictions, targets, 5) == .2, 'Recall@k should be equal to 2/10 = 0.2'
Precision@k is a standard information retrieval metric. For example, an interpretation of precision@k computed at 80% could be that that 80% of the total number of the recommendations made are relevant to the user.
More formally we have:
$$Precision@k = \frac{\text{number of recommended items @k that are relevant}}{\text{number of recommended items @k}}$$Arguments:
predictions = (5, 6, 32, 67, 1, 15, 7, 89, 10, 43)
targets = (15, 5, 44, 35, 67, 101, 7, 80, 43, 12)
assert precision_at_k(predictions, targets, 5) == .4, 'Recall@k should be equal to 2/5 = 0.4'

java.awt.geom
package.PathIterator
interface defines methods for retrieving elements from a path.Shape
interface provides a set of methods for describing and inspecting
geometric path objects. This interface is implemented by the
GeneralPath
class and other geometry classes.
All examples represented in this section create geometries by using java.awt.geom
and then render them
by using the
Graphics2D
class.
To begin you obtain a Graphics2D
object, for example
by casting the Graphics
parameter of the paint()
method.
public void paint (Graphics g) { Graphics2D g2 = (Graphics2D) g; ... }
Point
class creates a point representing a location in (x,y)
coordinate space.
The subclasses Point2D.Float
and Point2D.Double
provide correspondingly float and double precision
for storing the coordinates of the point.
//Create Point2D.Double Point2D.Double point = new Point2D.Double(x, y);
Point2D.Double()
.setLocation
method to set the position of the point as follows:
setLocation(double x, double y)
– To set the location of the point-
defining coordinates as double valuessetLocation(Point2D p)
– To set the location of the point using the coordinates of another point.Point2D
class has methods to calculate the distance between the current point and a point with
given coordinates, or the distance between two points.
Line2D
class represents a line segment in (x, y) coordinate space.
The Line2D.Float
and Line2D.Double
subclasses specify lines in float and double precision.
For example:
// draw Line2D.Double g2.draw(new Line2D.Double(x1, y1, x2, y2));
This class includes several setLine()
methods to define the endpoints of the line.
Aternatively, the endpoints of the line could be specified by using the constructor for the Line2D.Float
class as follows:
Line2D.Float(float X1, float Y1, float X2, float Y2)
Line2D.Float(Point2D p1, Point2D p2)
Stroke
object in the
Graphics2D
class to define the stroke for the line path.
java.awt.geom
package enables you to create a quadratic or cubic curve segment.
QuadCurve2D
class implements the Shape
interface.
This class represents a quadratic parametric curve segment in (x, y) coordinate space.
The QuadCurve2D.Float
and QuadCurve2D.Double
subclasses specify a quadratic curve
in float and double precision.
Several setCurve
methods are used to specify two endpoints and a control point of the curve,
whose coordinates can be defined directly, by the coordinates of other points and by using a given array.
A very useful method, setCurve(QuadCurve2D c)
, sets the quadratic curve with
the same endpoints and the control point as a supplied curve. For example:
// create new QuadCurve2D.Float QuadCurve2D q = new QuadCurve2D.Float(); // draw QuadCurve2D.Float with set coordinates q.setCurve(x1, y1, ctrlx, ctrly, x2, y2); g2.draw(q);
CubicCurve2D
class also implements the
Shape
interface.
This class represents a cubic parametric curve segment in (x, y) coordinate space.
CubicCurve2D.Float
and CubicCurve2D.Double
subclasses specify a cubic curve
in float and double precision.
The CubicCurve2D
class has similar methods for setting the curve as the
QuadraticCurve2D
class, except with a second control point. For example:
// create new CubicCurve2D.Double CubicCurve2D c = new CubicCurve2D.Double(); // draw CubicCurve2D.Double with set coordinates c.setCurve(x1, y1, ctrlx1, ctrly1, ctrlx2, ctrly2, x2, y2); g2.draw(c);
Rectangle
Classes that specify primitives represented in the following example extend the
RectangularShape
class, which implements theShape
interface and adds a few methods of its own.These methods enables you to get information about a shape’s location and size, to examine the center point of a rectangle, and to set the bounds of the shape.
The
Rectangle2D
class represents a rectangle defined by a location (x, y) and dimension (w x h). TheRectangle2D.Float
andRectangle2D.Double
subclasses specify a rectangle in float and double precision. For example:
// draw Rectangle2D.Double g2.draw(new Rectangle2D.Double(x, y, rectwidth, rectheight));The
RoundRectangle2D
class represents a rectangle with rounded corners defined by a location (x, y), a dimension (w x h), and the width and height of the corner arc. TheRoundRectangle2D.Float
andRoundRectangle2D.Double
subclasses specify a round rectangle in float and double precision.The rounded rectangle is specified with following parameters:
To set the location, size, and arcs of a
- Location
- Width
- Height
- Width of the corner arc
- Height of the corner arc
RoundRectangle2D
object, use the methodsetRoundRect(double a, double y, double w, double h, double arcWidth, double arcHeight)
. For example:
// draw RoundRectangle2D.Double g2.draw(new RoundRectangle2D.Double(x, y, rectwidth, rectheight, 10, 10));
Ellipse
TheEllipse2D
class represents an ellipse defined by a bounding rectangle. TheEllipse2D.Float
andEllipse2D.Double
subclasses specify an ellipse in float and double precision.Ellipse is fully defined by a location, a width and a height. For example:
// draw Ellipse2D.Double g2.draw(new Ellipse2D.Double(x, y, rectwidth, rectheight));
Arc
To draw a piece of an ellipse, you use theArc2D
class. This class represents an arc defined by a bounding rectangle, a start angle, an angular extent, and a closure type. TheArc2D.Float
andArc2D.Double
subclasses specify an ellipse in float and double precision.The
Arc2D
class defines the following three types of arcs, represented by corresponding constants in this class: OPEN, PIE and CHORD.Several methods set the size and parameters of the arc:
Also, you can use the
- Directly, by coordinates
- By supplied
Point2D
andDimension2D
- By copying an existing
Arc2D
setArcByCenter
method to specify an arc from a center point, given by its coordinates and a radius.
// draw Arc2D.Double g2.draw(new Arc2D.Double(x, y, rectwidth, rectheight, 90, 135, Arc2D.OPEN));The
ShapesDemo2D.java
code example contains implementations off all described geometric primitives. For more information about classes and methods represented in this section see thejava.awt.geom
specification.

--- layout: post title: Cloning Ubuntu Hardy image in VMWare Fusion post_id: 47 categories: - tips & tricks date: 2008-08-15 16:50:00.000000000 -06:00 author: Jamis permalink: 2008/8/15/cloning-ubuntu-hardy-image-in-vmware-fusion.html summary: > The author's attempts to clone a VMWare Fusion image are documented, with a solution described ---
Having spent the better part of a day googling and struggling, I figured it would possibly benefit others if I took a minute to post the steps I took to clone a VMWare Fusion image. The image in question is of Ubuntu Server (Hardy). I’m using VMWare Fusion 2 (beta 2).
Just find your “Virtual Machines” folder (should be in your Documents folder), and copy the image in question to a new location. (The images are actually folders; a simple “cp -R” worked fine for me.)
Then, open the copied image in VMWare Fusion and boot it. VMWare Fusion will ask if you if you copied or moved the image—be sure to say you copied it (that let’s VMWare set up a new MAC address for your image).
Go ahead and log in once the server boots. You’ll find networking is all hosed. To fix networking, this worked for me:
Once your machine comes back up, you should have a network again! Now, if only VMWare Fusion could bake all this in somehow… :/
(Related: installing VMWare Tools on Ubuntu server. It’s from 2006, but it still worked well enough for me, though I followed the instructions for tweaking the network that the VMWare Tools install gave at the end, rather than what this gent said.)

UNETBOOTIN(1) UNETBOOTIN(1) NAME unetbootin - program to install Linux/BSD distributions to a partition or USB drive SYNOPSIS unetbootin DESCRIPTION This manual page documents briefly the unetbootin command. unetbootin allows for the installation of various Linux/BSD distributions to a partition or USB drive, so it's no different from a standard install, only it doesn't need a CD. It can create a dual-boot install, or replace the existing OS entirely. AUTHOR unetbootin was written by Geza Kovacs<EMAIL_ADDRESS>This manual page was written by Eugene V. Lyubimkin<EMAIL_ADDRESS>for the Debian project (but may be used by oth‐ ers). November 2, 2008 UNETBOOTIN(1)


Scot is the Smart Contract Organizational token. It’s modeled after the SMT protocol and we literally use the SMT white paper as the basis for the design spec. SMTs are quite delayed so if you’d like a way to create and tokenize your community NOW we’re offering Scot as a way to do it through steem-engine.com!
Want to switch to SMTs later? Go ahead! We plan to help launch SMTs as well. Want to use our smart contract tool that we’re working on to distribute tokens in the future? That’s ok too. You can switch! We don’t really care which tool you decide to use for your community so long as it’s based on Steem!
Also, keep in mind, Scot and Scotbot are starting points to tokenize everything and they are expected to be available to the public starting in about a week (this is still notice of change rather than change itself) . They aren’t necessarily the end game. Some people may prefer this, others may want different tools, we’ll support as many tools as we can that we think will help grow Steem!
What’s happening?
In order for voting to work properly you need to be able to stake tokens. On Steem, the comparative ability is to take liquid steem and power it up into steem power. On the test server @harpagon made it so you can go from liquid tokens to token power and @beggars added a UI so users can Stake their tokens (aka power them up) with a few clicks.
With staking enabled we’re now able to run the voting bot that @holger80 made, which we’re calling Scotbot (ND Scot is also a term we’ll use).
We’ve been testing the staking feature on the QA server for the last week with the scottest token. We’ve been testing Scotbot with it too. It’s gone quite smoothly. So, today we’re announcing a Hard Fork for the Steem Engine platform to add the new staking functionality.
The hard fork is scheduled to take place on Tuesday, May 7th at 8pm EST on the main node that runs steem-engine.com. Anyone else who is running their own Steem Engine node should plan to update to the new software at around the same time (though it doesn’t have to be exact since all of the data and consensus still happens on the Steem blockchain).
Once the hardfork is done we’ll technically be able to run Scot and Scotbot on the live server! We will likely need time and tooling to bring on board everyone that wants their own community token, but you’re welcome to message aggroed in discord if you’d like to get moving as soon as possible.
What happens after it’s live?
Then we get rockin’ and rollin’ with Scot and Scotbot so anyone in the community can create a token and get their proof-of-brain-style reward system up and running.
- Step 1 you’ll create a token.
- Step 2 you may want to then airdrop that token. The interface for that should be out soon.
- Step 3 users will have to stake the token. There’s an easy UI built.
- Step 4 you’ll setup scotbot to start distributing your tokens.
- Step 5 users will post normally through steempeak, busy, steemit etc and they’ll add tags to the post based on the tokens they are looking to be rewarded in (yes, more than one will work, but we’re limiting to 5)
- Step 6 when the post reaches the specified payout period you can claim your rewards in the available Steem Engine token(s). After 7 days you can claim your Steem rewards normally.
It’s changable
You screwed up how Scotbot works and want a different distribution framework. This will be allowed!!! So, no, it’s not a smart contract yet. The token distributor can change the dynamics/settings of how it’s distributed. This is good and bad!
If you mess up or find there’s a better way for this to work with your community then you’re going to be happy you can change it. If you’re investing money into a community token and someone changes how it distributes you might get pissed.
This is a tool launch. You have to do your own due diligence on tokens and communities you want to put your money into to make sure that the people leading them aren’t horrible human beings that will rob you later. It’s crypto, be wary. The benefit though is that if there’s a better way for a token to operate then it can adjust easily on the fly.
What will running a Scot cost?
We have programming, server, and support costs to run these. I know lots of crypto people want everything for free, but we simply can’t offer that and still be a business that’s successful. Here’s the fees we’ll be charging.
Scotbot setup = 1000 ENG
Sctbot monthly charge = 1 ENG per active account per month.
This is billed in arrears. So, at the end of 30 days we’ll count how many unique, active accounts you had over the past month and invoice you for that many ENG. Failure to pay will result in termination of the Scotbot instance. (Tokens are still on chain, but it will cease distributing tokens).
Thinking of getting this rolling? Feel free to message me on Discord!
What’s coming next? Custom Interfaces!
What we’re trying to put into place is the ability to run a condenser clone that will feature your token as the post rewards. This is under development, but in theory you would go to a custom website like magictoken.xyz, and post there. All the post rewards would show you how much magic you’ve earned. It’s like your own personally-branded white label version of steemit.com. When you click the wallet it’ll bring you back to your token wallet in Steem-engine.com.
It’s under development and I’ll keep you posted.
