A check would be applied for the given model in case that the mark model model matches data model. If it don't match or the data model is empty, a flag success refers to will be set as false and nullptr will be returned. Above two situations won't emit markModelChanged() signals. Others will emits markModelChanged() signal. model set as nullptr is equivalent to delete mark model and will emit markModelChanged() signal

Replaces the old slice model with the given model and returns the old one.
The mark model corresponding to the slice model will be deleted once the old slice model is replaced, and a new mark model will be created. So it's caller's responsibility to save the corresponding mark model before the replacement takes place, and the old slice mark model and its ownership will be returned to the caller. Sets model as nullptr is equivalent to empty the slice data.

10.5 Bags, or Multisets—library(bags)
This library module provides operations on bags.
Bags are also known as multisets.
A bag B is a function from a set dom(
B)
to the non-negative integers.
For the purposes of this module, a bag is constructed from two functions:
bag
- creates an empty bag
bag(
E,
M,
B)
- extends the bag B with a new element E which occurs
with multiplicity M, and which precedes all elements of B
in Prolog's order.
 There
is one snag with this: what are we to make of
bag(f(a,Y), 1, bag(f(X,b), 1, bag)) ?
As a term it has two distinct elements, but f(a,b)
will be reported as
occurring in it twice. But according to the definition above,
bag(f(a,b), 1, bag(f(a,b), 1, bag))
is not the representation of any bag, that bag is represented by
bag(f(a,b), 2, bag)
alone. We are apparently stuck with a scheme which is only guaranteed
to work for "sufficiently instantiated" terms, but then, that's true of
a lot of Prolog code.
The reason for insisting on the order is to make union and
intersection linear in the sizes of their arguments.
library(ordsets)
does the same for ordinary sets.
Exported predicates:
is_bag(
+Bag)
-
recognises proper well-formed bags. You can pass variables to
is_bag/1
,
and it will reject them.
portray_bag(
+Bag)
-
writes a bag to the current output stream in a pretty form so that
you can easily see what it is. Note that a bag written out this
way can not be read back in. For that, use
write_canonical/1
.
The point of this predicate is
to have bags displayed nicely by print/1 and the debugger.
This will print things which are not fully instantiated, which is
mainly of interest for debugging this module.
checkbag(
:Pred,
+Bag)
-
is true when Bag is a Bag{E1:M1, ..., En:Mn} with elements Ei
of multiplicity Mi, and Pred(Ei, Mi) is true for each i.
mapbag(
:Pred,
+Bag)
-
is true when Bag is a Bag{E1:M1, ..., En:Mn} with elements Ei
of multiplicity Mi, and Pred(Ei) is true for each element Ei.
The multiplicities are ignored: if you don't want this, use
checkbag/2
.
mapbag(
:Pred,
+OldBag,
-NewBag)
-
is true when OldBag is a Bag{E1:M1, ..., En:Mn} and NewBag is a
Bag{F1:M'1, ..., Fn:M'n} and the elements of OldBag and NewBag
are related by Pred(Ei, Fj). What happens is that the elements
of OldBag are mapped, and then the result is converted to a bag,
so there is no positional correspondence between Ei and Fj.
Even when Pred is bidirectional,
mapbag/3
is not. OldBag should
satisfy is_bag/1
before mapbag/3
is called.
somebag(
:Pred,
+Bag)
-
is true when Bag is a Bag{E1:M1, ..., En:Mn} with elements Ei of
multiplicity Mi and Pred(Ei, Mi) is true of some element Ei and
its multiplicity. There is no version which ignores the Mi.
somechkbag(
:Pred,
+Bag)
-
is like
somebag(
Pred,
Bag)
, but commits to the first solution it
finds. For example, if p(X,X,_)
, somechk(p(X),
Bag)
would be an
analogue of memberchk/2
for bags.
bag_to_list(
+Bag,
-List)
-
converts a Bag{E1:M1, ..., En:Mn} to a list where each element
appears as many times as its multiplicity requires. For example,
Bag{a:1, b:3, c:2}
would be converted to [a,b,b,b,c,c]
.
bag_to_ord_set(
+Bag,
-Ordset)
-
converts a Bag{E1:M1, ..., En:Mn} to a list where each element
appears once without its multiplicity. The result is always an
ordered (representation of a) set, suitable for processing by
library(ordsets)
. See also bag_to_list/2
.
bag_to_ord_set(
+Bag,
+Threshold,
-Ordset)
-
given a Bag{E1:M1, ..., En:Mn} returns a list in standard order of
the set of elements {Ei | Mi >= Threshold}. The result is an Ordset.
list_to_bag(
+List,
-Bag)
-
converts a List to a Bag representing the same multi-set.
Each element of the List appears once in the Bag together
with the number of times it appears in the List.
bag_to_set(
+Bag,
-Set)
-
converts a Bag{E1:M1, ..., En:Mn} to a list which represents the
Set {E1, ..., En}. The order of elements in the result is not
defined: for a version where the order is defined use
bag_to_ord_set/2
.
bag_to_set(
+Bag,
+Threshold,
-Set)
-
given a Bag{E1:M1, ..., En:Mn} returns a list which represents the
Set of elements {Ei | Mi >= Threshold}. Because the Bag is sorted,
the result is necessarily an ordered set.
empty_bag(
?Bag)
-
is true when Bag is the representation of an empty bag. It can be
used both to make and to recognise empty bags.
member(
?Element,
?Multiplicity,
+Bag)
-
is true when Element appears in the multi-set represented by Bag
with the indicated Multiplicity. Bag should be instantiated,
but Element and Multiplicity may severally be given or solved for.
memberchk(
+Element,
?Multiplicity,
+Bag)
-
is true when Element appears in the multi-set represented by Bag,
with the indicated Multiplicity. It should only be used to check
whether a given element occurs in the Bag, or whether there is an
element with the given Multiplicity. Note that guessing the
multiplicity and getting it wrong may force the wrong choice of
clause, but the result will be correct if
is_bag(
Bag)
.
bag_max(
+Bag,
-CommonestElement)
-
unifies CommonestElement with the element of Bag which occurs
most often, picking the leftmost element if several have this
multiplicity. To find the multiplicity as well, use
bag_max/3
.
bag_max/2
and bag_min/2
break ties the same way.
bag_min(
+Bag,
-RarestElement)
-
unifies RarestElement with the element of Bag which occurs
least often, picking the leftmost element if several have this
multiplicity. To find the multiplicity as well, use
bag_min/3
.
bag_max/2
and bag_min/2
break ties the same way, so
bag_max(Bag, Elt), bag_min(Bag, Elt)
is true only when all the elements of Bag have the same multiplicity.
bag_max(
+Bag,
-CommonestElement,
-Multiplicity)
-
unifies CommonestElement with the element of Bag which occurs
most often, and Multiplicity with the multiplicity of that element.
If there are several elements with the same greatest multiplicity,
the left-most is returned.
bag_min/3
breaks ties the same way.
bag_min(
+Bag,
-RarestElement)
-
unifies RarestElement with the element of Bag which occurs
least often, and Multiplicity with the multiplicity of that element.
If there are several elements with the same least multiplicity,
the left-most is returned.
bag_max/3
breaks ties the same way, so
bag_max(Bag, Elt, Mult), bag_min(Bag, Elt, Mult)
is true only when all the elements of Bag have multiplicity Mult.
length(
+Bag,
-BagCardinality,
-SetCardinality)
-
unifies BagCardinality with the total cardinality of the multi-set
Bag (the sum of the multiplicities of its elements) and
SetCardinality with the number of distinct elements.
make_sub_bag(
+Bag,
-SubBag)
-
enumerates the sub-bags of Bag, unifying SubBag with each of them in
turn. The order in which the sub-bags are generated is such that if
SB2 is a sub-bag of SB1 which is a sub-bag of Bag, SB1 is generated
before SB2. In particular, Bag is enumerated first and bag last.
test_sub_bag(
+Bag,
+SubBag)
-
is true when SubBag is (already) a sub-bag of Bag. That is,
each element of SubBag must occur in Bag with at least the
same multiplicity. If you know SubBag, you should use this
to test, not
make_sub_bag/2
.
bag_union(
+Bag1,
+Bag2,
-Union)
-
unifies Union with the multi-set union of bags Bag1 and Bag2.
bag_union(
+ListOfBags,
-Union)
-
is true when ListOfBags is given as a proper list of bags and Union
is their multi-set union. Letting K be the length of ListOfBags,
and N the sum of the sizes of its elements, the cost is
O(N lg K).
bag_intersection(
+Bag1,
+Bag2,
-Intersection)
-
unifies Intersection with the multi-set intersection
of bags Bag1 and Bag2.
bag_intersection(
+ListOfBags,
-Intersection)
-
is true when ListOfBags is given as a non-empty proper list of Bags
and Intersection is their intersection. The intersection of an
empty list of Bags would be the universe with infinite multiplicities!
bag_intersect(
+Bag1,
+Bag2)
-
is true when the multi-sets Bag1 and Bag2 have at least one
element in common.
bag_add_element(
+Bag1,
+Element,
+Multiplicity,

Major things to know when building a house a commercial
Building a new home can be incredibly exciting. But many people find that they get so consumed by the design and project management aspects of their new home that crucial elements, such as its electrical requirements, can be overlooked. If you get these wrong, the consequences facing your home can range from mere inconvenience, right through to major health and safety risks.
- Plan the location of outlets
- Understand the wiring system you’ll need
- Know if you need extra power
- Consider energy efficiency
- Customisable lighting switches

A simple sequencer
The Sequencer actor stores a time-stamped list of messages to be sent to (other) actors. Any message that a client can send to an actor can be added to a SequenceActor and then played back later.
To use the Sequencer implementation, load seq.so and create an actor
of type SeqActor.
(Note: if you misspell SeqActor as
"SequenceActor" or "SequencerActor" (the way you probably pronounce it),
it'll still work. You'll get a SeqActor. No warning is issued for this.
Normally if you misspell an actor's name,
you get error messages about undefined actors and DSO's not loaded;
this case is an exception.)
SeqActor messages
In addition to the messages understood by all generator actors, the SeqActor understands the following messages:
- SetTempo hActor x
- Set the tempo of this sequence to x beats per minute (default is 60).
- SetBeatLength hActor x
- Set the tempo of this sequence to x seconds per beat (default is 1, obviously, from above).
- AddMessage hActor beat message...
- Add an event to the list at time beat, in beats from the start of the sequence. message... is the message to be sent.
- SetNumLoops hActor numloops
- Set the number of times to execute the body of the sequence.
Defaults to -1, which means to loop forever.
0 means don't do it at all (i.e., don't play anything);
1 means do it once;
2 means twice, and so on.
- SetLoopStart hActor beat
- Set the loop start point to beat (default 0).
- SetLoopEnd hActor beat
- Set the loop end point to beat (default 1 million).
- JumpTo hActor beat
- Change the position of playback to beat.
- Rewind hActor beat
- Change the position of playback, backwards, to beat. If beat is omitted, it defaults to zero.
- SkipEvents hActor count
- Fast-forward, skipping the next count events. (Skipping backwards doesn't work as of this writing.)
- Active hActor activeStatus
- Play or pause the sequence (activeStatus is 1 or 0 respectively).

Cuvette holder update¶
These instructions are for replacing the current 2-part cuvette holder with a 3-part version. We will be adding these parts to the main kit shortly.
Hardware¶
| Qty | Description | Vendor | Part # | |
|---|---|---|---|---|
| 4 | Cuvette standoffs: male-female | 4-40 hex standoffs 3/8” long | mcmaster-carr | 93505A116 |
| 2 | Cuvette standoffs: female | 4-40 hex standoffs 3/8” long | mcmaster-carr | 91780A509 |
| 4 | Cuvette screws | 4-40 machine screws, 3/8” long | mcmaster-carr | 91249A108 |
| 1 | Black acrylic cuvette holder with cutout | |||
| 2 | Black acrylic cuvette holder |
Assembly¶
Step 1. Using two of the screws, mount the first pair of male-female cuvette standoffs.
Step 2. Place the black acrylic cuvette holder with the cutout onto the standoffs as shown in the image below.
Step 3. Mount the second pair of male-female cuvette standoffs.
Step 4. Place the LED and sensor components onto the colorimeter base here. This assumes you already have assembled these parts as described in Steps 6-9 of Assembly of the colorimeter. Orient the parts as shown in the image below.
Step 5. Next step, place one of the two regular black acrylic cuvette holders onto the standoffs and mount the last two female cuvette standoffs.
Step 6.  Continue to assemble the rest of the colorimeter from Step 11 of Assembly of the colorimeter.


Here are step-by-step instructions for how to use our website!
First, you choose which attributes you would like your image classified by. You can choose any combination of style, genre, and artist. You must choose at least one though!
You can then choose which image you would like to classify. Click the Choose button to open the file explorer.
Once the file explorer opens, choose which photo you want to classify. You can only choose a single image at a time. You can only upload images of type png, jpg, jpeg, and gif. Any other type of file will cause an error and you will be asked to upload a different file.
Now that you have choosen an image, you can run the model by clicking on the Run button! Our website will then classify the image by the catagories that you choose, in this case Artist.
Our website will then automatically scroll to the results at the bottom of the page. There will be results for each classiciation type that you choose, with classifications ranked in order of likelyhood. That is, in the example below our classifier believes that there is a 83% chance that the artist is Vincent van Gogh. We also provide images that are similar to the top classification identified by our model. We hope that you will discover new art that is similar to the one that you wanted to learn more about with our website!
We trained our models on art from the WikiArt dataset on the ArtGAN Github, which can be found here. This dataset has 27 different styles, 10 genres, and 23 artists. We have a limited number of classifications within each class due to needing a large number of photos for each classification in order to train a successful model.
Here is a complete list of the all of the styles, genres, and artists that our models are capable of classifying.
Styles: Abstract Expressionism, Action Painting, Analytical Cubism, Art Nouveau, Baroque, Color Field Painting, Contemporary Realism, Cubism, Early Renaissance, Expressionism, Fauvism, High Renaissance, Impressionism, Mannerism Late Renaissance, Minimalism, Naive Art Primitivism, New Realism, Northern Renaissance, Pointillism, Pop Art, Post Impressionism, Realism, Rococo, Romanticism, Symbolism, Synthetic Cubism, and Ukiyo-e.
Genres: Abstract, Cityscape, Genre Art, Illustration, Landscape, Nude Painting, Portrait, Religious painting, Sketch and Study, and Still Life.
Artists: Albrecht Durer, Boris Kustodiev, Camille Pissarro, Childe Hassam, Claude Monet, Edgar Degas, Eugene Boudin, Gustave Dore, Ilya Repin, Ivan Aivazovsky, Ivan Shishkin, John Singer Sargent, Marc Chagall, Martiros Saryan, Nicholas Roerich, Pablo Picasso, Pablo Cezanne, Pierre Auguste Penoir, Pyotr Konchalovsky, Raphael Kirchner, Rembrandt, Salvador Dali, and Vincent van Gogh.

Conversation with one's self through writing
In the Frog Cult, we believe that each individual frogs and people have to spend time building a bond with themselves.
Or else, the heart gets lonely as we don't pay attention to it. We feel like we are lonely because we don't get to
talk to others and others don't understand us. In reality, we don't talk to ourselves and we don't understand
ourselves. The source of our loneliness is in our hearts, it wishes to communicate with us ever since we are born.
One of the easiest ways to communicate with our heart is to write a question on piece of paper. Let your hand
answer you back with whatever comes to your mind first. Let it flow and trust in yourself. It may not feel right
in the beginning, but every bond begins like a plant. The more you spend time watering and caring for it, the
better it becomes and one day - it will give you its fruit.
In the case of our heart, it will offer you wisdom and insight beyond your expectations. That is why it is preferable
to start paying attention to your core. After some time, you will not feel as lonely as before and you will not need
any external influence to keep you happy. Once your roots are strong, your heart and mind will be in harmony. This
whole thing can be achieved by just communicating with yourself - we highly recommend you to have a dialogue on a paper.

Being cautious about the Seed of Actions
"History is not a dead fact
It is a living organism" -
A wise man
Seed of actions is a phenomenon that is probably as old as time. In simple words, it can be described
as an action or cause, that will have a long-lasting effect. Almost the same as a frog giving birth to
a new frog, each action will produce an effect, which would change the course of the next actions.
To understand this notion, we need to know what "time" is. Time is an order of this realm which deals
with the sequence of actions. Seed of actions affect not just individuals within one lifetime, it directly
and strongly affects lineage and those frogs around the individuals.
In the beginning, there will be thoughts, they come together to form a decision, the decision becomes
a cause, and the cause becomes aneffect. It is similar to chess - there are no right or wrong moves,
there are only good and bad moves. If the move was good, your next position will have a strong advantage,
if not, then it's the other way around.
When it comes to the seed of actions, whatever seed you plant, you will get a result in the coming
days, weeks, months, years, and generations - what goes in, goes out. If you are feeling happy or feeling
miserable, it helps to think and remember the roots of the effect that you are experiencing.
Who implanted the actions, which affected you to have your current state. Once you figure out the
roots of the effect, you will be able to fix or prolong the effect in any way you wish.
In life, there are only three truths, Birth, Death and Seed of Actions. Anything else is debatable.
Each living being carries the three in their body. The three are actually one. let's imagine,
your great grandfather didn't go to school, but he knew the importance of knowledge and discipline.
So, he sent your grandfather to school despite all the work and hardship. That choice was a good seed of
action which resulted positively on the future of his descendants. Your grandfather had a good life and
sent your father to school. It was a seed from the previous action. Today, you are living well,
thanks to the good deeds of your forefathers.
 Actions such as hurting people and animals physically or emotionally, polluting the nature and
disrespecting fire. This perspective gives much more insight into life and it will help you
to understand your situation better so that you can make better decisions in the future. It might sound
like something simple, but this is one of the foundational concepts of life, that should be taken seriously
:)

Looking from the Perspective of Death
Death - is it our foe or ally? What if Death is already at the doorstep? What will matter when your
end comes? Should you be scared of it? Or, should you welcome it, like an old friend? (HP reference)
Death is usually like that gloomy, unpopular kid, who is always in the corner alone, while all others are
having fun, dancing, singing and drinking. Most of the people would try to avoid the kid, as it's not pleasant
to be around Death.
In the Frog Cult, we believe that Death is our good friend. It's the only certainty in life.
All others are objects of subjectivity - what is valuable today can become trash tomorrow.
So, at least once a week, we should hang out with Death.
A clear mind is preferable when you wish to stand side by side with the kid, as thoughts and fears
pollute the clarity. When we see from the perspective of Death, we start to see what is essential and what is not.
The majority of the materialistic items we possess today will vanish in the coming years and decades
together with our bodies. What will stay is our legacy, memories, nature, and most importantly -
our seeds of actions.
Many frogs and people carry sadness, misunderstandings, regrets, grudges towards others. When we have time, we are
distracted by the issues of the external world, and we don't pay much attention to the problems of our inner world.
When our body is broken (a reference to LOTR), all the external distractions fade away. What stays with us is our
inner world - all the feelings we carried throughout our life. If we are satisfied without any regrets, we will greet
Death with open arms, like an old friend.
If not, then we will beg for more time to accomplish things we failed to do when we had the possibilities.
Fearing your end or chilling with your old friend - it's all up to you.
We highly recommend you to imagine that Death will come for you in 2 hours - how would you feel, and what would you do
within that amount of time? That way, you will know your true priorities in life.
"Suffering is at the edge of joy
Joy is at the edge of suffering
Lie is at the edge of truth
Truth is at the edge of death"

Alberta to widen Highway 1A with land transfer from First Nation
by CP, The Canadian PressThe Alberta government will be widening 29 kilometres of Highway 1A west of Calgary.
The $76.5-million project is to double the width of the section between Cochrane and Canmore.
The government says it has signed an agreement for a transfer of lands needed for the upgrade with Stoney Nakoda First Nation.
Construction is also to smooth dips and straighten curves on the road, build shoulders on the sides and make ditches wider and less steep.
The project is to take two to three years.
Premier Jason Kenney says the expansion is important for Albertans.
“I am proud that we have made this agreement with the Stoney Nakoda. This highway expansion will improve both safety and economic opportunities, while ensuing that our First Nations are real partners in prosperity,” he said in a news release.

Cryptography Audit
Transcript By: Bryan Bishop
Category: Conference
libsecp256k1-zkp audit
John Woeltz
It’s a real treat to be able to be a part of this.
Why bother?
Just a high-level, why are we taking community resources to spend time on audits? There are some perspectives– it’s good for the community and it’s what you do.
Bitcoin had on professional security audits and did just fine. But it launched in a very different environment, and it did get audits eventually.
 For projects like grin, it’s more than just people covering their asses and taking losses for the community. This is a privacy-oriented project that I think is intended to use in real life.
Reduce scope for pre-launch audit to secp256k1-zkp
libsecp256k1-zkp is an extension of libsecp256k1 to add bulletproof rangeproofs and an aggsig module. This library supports critical cryptographic operations that grin relies on. The audit was paid by an anonymous donor, and the community security fund was not deducted from. The primary auditor was JP Aumasson. He’s a cryptographer who created the BLAKE hash function, SipHash pseudorandom function and Gravity-SPHINCS signature scheme.
So we did a reduced-scope audit for the library. We looked for the following things, which are all pretty standard things to check for. We looked for sidechannel leaks (like timing leaks), software safety such as memory leaks or API abuse, usage of underlying cryptographic primitives, RNG/PRNG problems, cryptographic security level (e.g. key lengths and parameters and magic numbers), decoding serialized/DER data which is notoriously buggy. For PRNG it’s important to not pull entropy from system time or somtehing like that.
I’m just going to step through some of the things we found. None of them are groundbreaking or earthshattering. It’s good to look at these things though and see what has been thought about.
Some bugs we found
The compiler could potentially optimizee out a dead assignment that might leak sensitive data. This was in /src/ecmulti_gen_impl.h at line 153, bits = 0 which is used to overwrite the value of private bits may be removed by compiler since “bits” is no longer used. After compilation, you have to check if the compiler has optimized that out.
There was also missing null pointer checks. There were missing null pointer checks in secp256k1_aggsig_sign_single, secp256k1_aggsig_verify_single, secp256k1_aggsig_add_signatures_single. This was fixed by yeastplume.
There was unfreed heap allocations found. There was also unchecked heap allocation, which could get you a null return, which isn’t that good if you’re relying on that library and you’re not prepared to handle that null value. As a library that other things are relying on, these things are important to clean up.
There was also an unnecessary operation in secp256k1_aggsig_content_something. It just increases attack surface. So you should remove anything you don’t actually use.
There was an opportunity for faster rejection of invalid parameters in secp256k1_bulletproof_rangeproof_prove. This has been implemented now.
There is a pull request with fixes submitted by yeastplume: https://github.com/mimblewimble/secp256k1-zkp/pull/37
Next steps for grin audits
Mainnet is already launched. We want to add more features and grow. But it’s still important to take security seriously and to, again like I was saying before, you need a good perspective on it. It’s not a magic bullet. But you also have to do what you can to beresponsible to your community.
The next thing for the audit are some rust, and hopefully that will have less memory errors. We’ll look at grin core crate, grin keychain create, grin chain crate. We’re waiting on some bids to review, and we want to compare a few different firms to see which timelines and what the community is going to get. We’re still trying to reach a decision on that.

ComputeThreadPool
public protocol ComputeThreadPool
Allows efficient use of multi-core CPUs by managing a fixed-size collection of threads.
From first-principles, a (CPU) compute-bound application will run at peak performance when overheads are minimized. Once enough parallelism is exposed to leverage all cores, one of the key overheads to minimize is context switching, and thead creation / destruction. The optimal system configuration is thus a fixed-size threadpool where there is exactly one thread per CPU core (or rather, hyperthread). This configuration results in zero context switching, no additional kernel calls for thread creation & deletion, and full utilization of the hardware.
Unfortunately, in practice, it is infeasible to statically schedule work apriori onto a fixed pool of threads. Even when applying the same operation to a homogenous dataset, there will inevitably be variability in execution time. (This can arise from I/O interrupts taking over a core [briefly], or page faults, or even different latencies for memory access across NUMA domains.) As a result, it is important for peak performance to build abstractions that are flexible and dynamic in their work allocation.
The ComputeThreadPool
protocol is a foundational API designed to enable efficient use of
hardware resources. There are two APIs exposed to support two kinds of parallelism. For
additional details, please see the documentation associated with each.
Note: be sure to avoid executing code on the ComputeThreadPool
that is not compute-bound. If
you are doing I/O, be sure to use a dedicated threadpool, or use
Swift NIO for high performance non-blocking I/O.
Note: while there should be only one “physical” threadpool process-wide, there can be many
virtual threadpools that compose on top of this one to allow configuration and tuning. (This is
why ComputeThreadPool
is a protocol and not static methods.) Examples of additional threadpool
abstractions could include a separate threadpool per-NUMA domain, to support different
priorities for tasks, or higher-level parallelism primitives such as “wait-groups”.

LBW requires Interix, a.k.a. Services for Unix, a.k.a. Subsystem for Unix Applications, a.k.a. Microsoft Unix.
This is a Microsoft product that nobody's ever heard of. It provides a rather decent if dated Unix system that runs side-by-side with win32, on top of the Windows NT kernel. It comes with all the usual development tools, like gcc, make, a full set of Unix command line utilities and daemons, etc. LBW development is done on Interix.
It's free and easy to install, but it is irritatingly fiddly.
Run the executable. It'll decompress into a folder. Then run the installer in that folder. It'll ask you a series of questions:
It may take a while at the 'configuring security services' stage --- let it run, it'll get there in the end.
Once finished, it'll make you reboot.
Interix does not install out of the box on XP Home, because Microsoft apparently think you're too cheap.
However, it's trivially easy to hack the installer to work. You will need a hex editor.
First, download and decompress the Services for Unix installer as described above. Then, load the SfuSetup.msi file into your hex editor. Search for:
NOT (VersionNT = 501 AND MsiNTSuitePersonal)
Change the 501 to 510 and save.
You can now proceed with the installation as described above.
I don't know --- I don't have access to a Windows Vista machine. I think it's like Windows 7 (see below). I do know that Interix is only available on Vista Pro and Vista Ultimate systems.
If you get Interix working on Vista, please let me know so I can update this page!
Interix is built in, but disabled.
To enable it, go to Control Panel -> Programs and Features and check the 'Subsystem for Unix-based Applications' and turn it on. You'll have to reboot.
[If you want to do LBW development, you'll need to do more than this --- ask on the mailing list.]

Need some code outside admons for color and font comparisons:
def some_code(x):
return sin(x)*exp(1-x)
And some plain text verbatim:
x=1.0 y=0.9 z=0.4
x=1.1 y=0.3 z=0.1
Here is a plain quote environment.
Sayre's law states that "in any dispute the intensity of feeling is inversely proportional to the value of the issues at stake."

Source: wikipedia
Does quotes with title also work? No...cannot work in LaTeX and HTML and then it does not make sense to support it.
A plain box is sometimes useful. Let's show it here for comparison with admons (especially the block admon has much in common with a box). The box is more aimed at framing a law or an equation.
First a simple block with text, an equation, and a list:
Let's begin a new paragraph and show a box with code only:
def some_code(x):
return sin(x)*exp(1-x)
Let us start with a plain warning environment.
Test warning with title:
Also some code:
def f(x):
return x
And a complete program
print "Hello, World!"
Test warning with large title with math:
Then we test a block, which is guaranteed to never have any admon icon.
import urllib
def grab(url, filename):
urllib.urlretrieve(url, filename=filename)
Next is a warning without a title ("none" implies no title).
Here is a long notice environment with a custom title and much text, math and code.
Let us start with some equations: $$ \begin{align*} \frac{Du}{dt} &= 0 \\ \frac{1}{2} &= {1/2}\\ \frac{1}{2}\pmb{x} &= \pmb{n} \end{align*} $$
The implementation of such complicated equations in computer code is task that this "Going deeper" environment targets.
def Dudt(u):
r = diff(u, t) + u*grad(u)
return r
half = 0.5
x = 2*n
And some more text that can help going into the next page. Longer computer code requires vertical space:
class Diff:
def __init__(self, f, h=1E-5):
self.f = f
self.h = float(h)
class Forward1(Diff):
def __call__(self, x):
f, h = self.f, self.h
return (f(x+h) - f(x))/h
class Backward1(Diff):
def __call__(self, x):
f, h = self.f, self.h
return (f(x) - f(x-h))/h
class Central2(Diff):
def __call__(self, x):
f, h = self.f, self.h
return (f(x+h) - f(x-h))/(2*h)
class Central4(Diff):
def __call__(self, x):
f, h = self.f, self.h
return (4./3)*(f(x+h) - f(x-h)) /(2*h) - \
(1./3)*(f(x+2*h) - f(x-2*h))/(4*h)
class Central6(Diff):
def __call__(self, x):
f, h = self.f, self.h
return (3./2) *(f(x+h) - f(x-h)) /(2*h) - \
(3./5) *(f(x+2*h) - f(x-2*h))/(4*h) + \
(1./10)*(f(x+3*h) - f(x-3*h))/(6*h)
class Forward3(Diff):
def __call__(self, x):
f, h = self.f, self.h
return (-(1./6)*f(x+2*h) + f(x+h) - 0.5*f(x) - \
(1./3)*f(x-h))/h
And then we add a figure too.
A bit of text before the summary, which we now call "Concluding remarks, for the novice", just because we can.

This chapter provides information about the internal structure of the library, how to control the configuration when building it, and how to add new support to the library. The following sections are found in this chapter:
Information on compiling the library is given elsewhere in this documentation. This section describes the low-level mechanisms used to control the optional parts of the library that are configured at build time. Control is based on a collection of C defines that are specified either on the compiler command line or in a configuration file such as port.h (as generated by the configure script for UNIX systems) or tiffconf.h.
Configuration defines are split into three areas:
If the define COMPRESSION_SUPPORT is not defined then a default set of compression schemes is automatically configured:
To override the default compression behaviour define COMPRESSION_SUPPORT and then one or more additional defines to enable configuration of the appropriate codecs (see the table below); e.g.
#define COMPRESSION_SUPPORT #define CCITT_SUPPORT #define PACKBITS_SUPPORTSeveral other compression schemes are configured separately from the default set because they depend on ancillary software packages that are not distributed with libtiff.
Support for JPEG compression is controlled by JPEG_SUPPORT. The JPEG codec that comes with libtiff is designed for use with release 5 or later of the Independent JPEG Group's freely available software distribution. This software can be retrieved from the directory ftp.uu.net:/graphics/jpeg/.
Enabling JPEG support automatically enables support for the TIFF 6.0 colorimetry and YCbCr-related tags.
Experimental support for the deflate algorithm is controlled by DEFLATE_SUPPORT. The deflate codec that comes with libtiff is designed for use with version 0.99 or later of the freely available libz library written by Jean-loup Gailly and Mark Adler. The data format used by this library is described in the files zlib-3.1.doc, and deflate-1.1.doc, available in the directory ftp.uu.net:/pub/archiving/zip/doc. The library can be retried from the directory ftp.uu.net:/pub/archiving/zip/zlib/ (or try quest.jpl.nasa.gov:/beta/zlib/).
The deflate algorithm is experimental. Do not expect to exchange files using this compression scheme; it is included only because the similar, and more common, LZW algorithm is claimed to be governed by licensing restrictions.
By default tiffconf.h defines COLORIMETRY_SUPPORT, YCBCR_SUPPORT, and CMYK_SUPPORT.
| Define | Description |
|---|---|
| CCITT_SUPPORT | CCITT Group 3 and 4 algorithms (compression codes 2, 3, 4, and 32771) |
| PACKBITS_SUPPORT | Macintosh PackBits algorithm (compression 32773) |
| LZW_SUPPORT | Lempel-Ziv & Welch (LZW) algorithm (compression 5) |
| THUNDER_SUPPORT | 4-bit run-length encoding scheme from ThunderScan (compression 32809) |
| NEXT_SUPPORT | 2-bit encoding scheme used by NeXT (compression 32766) |
| OJPEG_SUPPORT | obsolete JPEG scheme defined in the 6.0 spec (compression 6) |
| JPEG_SUPPORT | current JPEG scheme defined in TTN2 (compression 7) |
| ZIP_SUPPORT | experimental Deflate scheme (compression 32946) |
| PIXARLOG_SUPPORT | Pixar's compression scheme for high-resolution color images (compression 32909) |
| SGILOG_SUPPORT | SGI's compression scheme for high-resolution color images (compression 34676 and 34677) |
| COLORIMETRY_SUPPORT | support for the TIFF 6.0 colorimetry tags |
| YCBCR_SUPPORT | support for the TIFF 6.0 YCbCr-related tags |
| CMYK_SUPPORT | support for the TIFF 6.0 CMYK-related tags |
| ICC_SUPPORT | support for the ICC Profile tag; see The ICC Profile Format Specification, Annex B.3 "Embedding ICC Profiles in TIFF Files"; available at http://www.color.org |
This software is developed on Silicon Graphics UNIX systems (big-endian, MIPS CPU, 32-bit ints, IEEE floating point). The configure shell script generates the appropriate include files and make files for UNIX systems. Makefiles exist for non-UNIX platforms that the code runs on -- this work has mostly been done by other people.
In general, the code is guaranteed to work only on SGI machines. In practice it is highly portable to any 32-bit or 64-bit system and much work has been done to insure portability to 16-bit systems. If you encounter portability problems please return fixes so that future distributions can be improved.
The software is written to assume an ANSI C compilation environment. If your compiler does not support ANSI function prototypes, const, and <stdarg.h> then you will have to make modifications to the software. In the past I have tried to support compilers without const and systems without <stdarg.h>, but I am no longer interested in these antiquated environments. With the general availability of the freely available GCC compiler, I see no reason to incorporate modifications to the software for these purposes.
An effort has been made to isolate as many of the operating system-dependencies as possible in two files: tiffcomp.h and libtiff/tif_<os>.c. The latter file contains operating system-specific routines to do I/O and I/O-related operations. The UNIX (tif_unix.c) code has had the most use.
Native CPU byte order is determined on the fly by the library and does not need to be specified. The HOST_FILLORDER and HOST_BIGENDIAN definitions are not currently used, but may be employed by codecs for optimization purposes.
The following defines control general portability:
| BSDTYPES | Define this if your system does NOT define the usual BSD typedefs: u_char, u_short, u_int, u_long. |
| HAVE_IEEEFP | Define this as 0 or 1 according to the floating point format supported by the machine. If your machine does not support IEEE floating point then you will need to add support to tif_machdep.c to convert between the native format and IEEE format. |
| HAVE_MMAP | Define this if there is mmap-style support for mapping files into memory (used only to read data). |
| HOST_FILLORDER | Define the native CPU bit order: one of FILLORDER_MSB2LSB or FILLORDER_LSB2MSB |
| HOST_BIGENDIAN | Define the native CPU byte order: 1 if big-endian (Motorola) or 0 if little-endian (Intel); this may be used in codecs to optimize code |
On UNIX systems HAVE_MMAP is defined through the running of the configure script; otherwise support for memory-mapped files is disabled. Note that tiffcomp.h defines HAVE_IEEEFP to be 1 (BSDTYPES is not defined).
The software makes extensive use of C typedefs to promote portability. Two sets of typedefs are used, one for communication with clients of the library and one for internal data structures and parsing of the TIFF format. There are interactions between these two to be careful of, but for the most part you should be able to deal with portability purely by fiddling with the following machine-dependent typedefs:
| uint8_t | 8-bit unsigned integer | tiff.h |
| int8_t | 8-bit signed integer | tiff.h |
| uint16_t | 16-bit unsigned integer | tiff.h |
| int16_t | 16-bit signed integer | tiff.h |
| uint32_t | 32-bit unsigned integer | tiff.h |
| int32_t | 32-bit signed integer | tiff.h |
| dblparam_t | promoted type for floats | tiffcomp.h |
(to clarify dblparam_t, it is the type that float parameters are promoted to when passed by value in a function call.)
The following typedefs are used throughout the library and interfaces to refer to certain objects whose size is dependent on the TIFF image structure:
| typedef unsigned int ttag_t; | directory tag |
| typedef uint16_t tdir_t; | directory index |
| typedef uint16_t tsample_t; | sample number |
| typedef uint32_t tstrip_t; | strip number |
| typedef uint32_t ttile_t; | tile number |
| typedef int32_t tsize_t; | i/o size in bytes |
| typedef void* tdata_t; | image data ref |
| typedef void* thandle_t; | client data handle |
| typedef int32_t toff_t; | file offset (should be off_t) |
| typedef unsigned char* tidata_t; | internal image data |
Note that tstrip_t, ttile_t, and tsize_t are constrained to be no more than 32-bit quantities by 32-bit fields they are stored in in the TIFF image. Likewise tsample_t is limited by the 16-bit field used to store the SamplesPerPixel tag. tdir_t constrains the maximum number of IFDs that may appear in an image and may be an arbitrary size (without penalty). ttag_t must be either int, unsigned int, pointer, or double because the library uses a varargs interface and ANSI C restricts the type of the parameter before an ellipsis to be a promoted type. toff_t is defined as int32_t because TIFF file offsets are (unsigned) 32-bit quantities. A signed value is used because some interfaces return -1 on error (sigh). Finally, note that tidata_t is used internally to the library to manipulate internal data. User-specified data references are passed as opaque handles and only cast at the lowest layers where their type is presumed.
The library is designed to hide as much of the details of TIFF from applications as possible. In particular, TIFF directories are read in their entirety into an internal format. Only the tags known by the library are available to a user and certain tag data may be maintained that a user does not care about (e.g. transfer function tables).
To add builtin support for a new compression algorithm, you can either use the "tag-extension" trick to override the handling of the TIFF Compression tag (see Adding New Tags), or do the following to add support directly to the core library:
A codec, say foo, can have many different entry points:
TIFFInitfoo(tif, scheme)/* initialize scheme and setup entry points in tif */ fooSetupDecode(tif) /* called once per IFD after tags has been frozen */ fooPreDecode(tif, sample)/* called once per strip/tile, after data is read, but before the first row is decoded */ fooDecode*(tif, bp, cc, sample)/* decode cc bytes of data into the buffer */ fooDecodeRow(...) /* called to decode a single scanline */ fooDecodeStrip(...) /* called to decode an entire strip */ fooDecodeTile(...) /* called to decode an entire tile */ fooSetupEncode(tif) /* called once per IFD after tags has been frozen */ fooPreEncode(tif, sample)/* called once per strip/tile, before the first row in a strip/tile is encoded */ fooEncode*(tif, bp, cc, sample)/* encode cc bytes of user data (bp) */ fooEncodeRow(...) /* called to decode a single scanline */ fooEncodeStrip(...) /* called to decode an entire strip */ fooEncodeTile(...) /* called to decode an entire tile */ fooPostEncode(tif) /* called once per strip/tile, just before data is written */ fooSeek(tif, row) /* seek forwards row scanlines from the beginning of a strip (row will always be >0 and <rows/strip */ fooCleanup(tif) /* called when compression scheme is replaced by user */
Note that the encoding and decoding variants are only needed when a compression algorithm is dependent on the structure of the data. For example, Group 3 2D encoding and decoding maintains a reference scanline. The sample parameter identifies which sample is to be encoded or decoded if the image is organized with PlanarConfig=2 (separate planes). This is important for algorithms such as JPEG. If PlanarConfig=1 (interleaved), then sample will always be 0.
The library handles most I/O buffering. There are two data buffers when decoding data: a raw data buffer that holds all the data in a strip, and a user-supplied scanline buffer that compression schemes place decoded data into. When encoding data the data in the user-supplied scanline buffer is encoded into the raw data buffer (from where it is written). Decoding routines should never have to explicitly read data -- a full strip/tile's worth of raw data is read and scanlines never cross strip boundaries. Encoding routines must be cognizant of the raw data buffer size and call TIFFFlushData1() when necessary. Note that any pending data is automatically flushed when a new strip/tile is started, so there's no need do that in the tif_postencode routine (if one exists). Bit order is automatically handled by the library when a raw strip or tile is filled. If the decoded samples are interpreted by the decoding routine before they are passed back to the user, then the decoding logic must handle byte-swapping by overriding the tif_postdecode routine (set it to TIFFNoPostDecode) and doing the required work internally. For an example of doing this look at the horizontal differencing code in the routines in tif_predict.c.
The variables tif_rawcc, tif_rawdata, and tif_rawcp in a TIFF structure are associated with the raw data buffer. tif_rawcc must be non-zero for the library to automatically flush data. The variable tif_scanlinesize is the size a user's scanline buffer should be. The variable tif_tilesize is the size of a tile for tiled images. This should not normally be used by compression routines, except where it relates to the compression algorithm. That is, the cc parameter to the tif_decode* and tif_encode* routines should be used in terminating decompression/compression. This ensures these routines can be used, for example, to decode/encode entire strips of data.
In general, if you have a new compression algorithm to add, work from the code for an existing routine. In particular, tif_dumpmode.c has the trivial code for the "nil" compression scheme, tif_packbits.c is a simple byte-oriented scheme that has to watch out for buffer boundaries, and tif_lzw.c has the LZW scheme that has the most complexity -- it tracks the buffer boundary at a bit level. Of course, using a private compression scheme (or private tags) limits the portability of your TIFF files.

I am a front-end web developer, UI/UX architect, video gamer, hiker of mountains, and lover of all sports. I have been working as a web developer for the Univeristy of Georgia's Marketing and Communications Division over a year and a half. Working at UGA has really driven my hunger to learn as much as I can in the industry to make their web presence a leader in the higher-ed sector. I have been actively involving myself in every day learning and innovating our tech stack with the vast amount of new tools being created for the web. I love learning new software that challenges my critical thinking and also going back to enhance skills I have been working on for years.
I grew up in the flat lands of rural Iowa until I was about 18 years old. Since then, I have lived near the Appalachian Mountains and hiking has become one of my favorite hobbies. When I am not exploring new trails, I also genuinely enjoy watching and playing sports. I was on the rugby team for the University of South Carolina, where we were ranked one of the top 25 teams in the country every season I played. Sports have been a centralized part of my life, and fueled the competitive edge that I have brought to my professional working career.
With my broad design background paired with my development skills, I am excited to help build exquisite websites and applications that will help make the internet more appealing and interactive for us all!


buildQuery
is used once the fluent calls have been made (that provide the url, from, sort, filter, select, skip, take, and orderby odata query criteria).
returns a BuildQueryResult that holds the resulting odata url or the error message (if an error occured)
expand
is very powerful and is used to indicate related data to include in the result. Typically this would be arrays of child, grandchild, ... data, returned in a nested hierarchy under the returned entities.
filter
is used to restrict the results based on filter criteria. odata filtering has a rich syntax (scroll down to section 4.5, filters
)
fromm
is used to provide the resource against which the odata query will be run
inlineCount
is used to request a property in the odata query result that indicates how many entities match the odata query. This is typically used in paging to indicate how many rows are available.
orderBy
is used to specify the properties used to control (ascending (default) or descending) the sort order for the resulting entities
select
is used to provide a comma-separated list of properties which restricts (filters out) data which isn't requied, increasing query efficiency and reducing required network bandwidth.
skip
indicates how many entities to skip in the result set (these entities are not returned). skip
is typically used in conjunction with take to implement paging
take
indicates how many entities to return from the result set. take
actually translates to $top
in the odata query.
url
is used to provide the base url from which the odata query is based
Generated using TypeDoc
The OdataHelper provides a fluent api for constructing odata urls
