CrisF29-Dec-19 02:41 AM
Seems like I've been missing a big conversation.
The above summary of your though has some good ideas worth implementing, imo, @artik123 .
With the goal of having your ideas provide true benefit I have a question.
I'm curious, what are you going to contribute (do) to start putting these ideas into practice?
---
Here is an example of what I mean:
I also would like to see more people build on the modules. I recognize that for many devs this can may take more resources and skills they have at the moment.
As steps towards having more people start building on the platform I have been actively approaching both projects that have the resources and devs that have the motivation to start working on this. There have been enough minor successes to continue down this path.
Also, I have found that actively participating in testing and using the various tools has given me the chance to see some of my (small) suggestions implemented.
My technical skills are very low, but even so I have found many areas where I am able to do things that contribute towards seeing my ideas becoming reality.
---
I'm not suggesting that this is the path you should take. Just giving an example of doing what my current skills and situation allow to see my ideas bring concrete results.
With your technical skills I imagine that your contributions would bring everyone great benefit, as your ideas are realized.

Although I shouldn't be replying in this channel I felt a strong need to. Apologies
I'll head over to #dev-general after suggesting that others, who are interested, follow the full discussion in the other channels.(edited)
artik12329-Dec-19 03:00 AM
@CrisF My situation is very unique (i don't wish to elaborate more on that). In the past I have made a project or two for this community and also been a x4 notary node operator for a year and a half. If these ideas go through, it's worth x100 more than I could ever possibly do.(edited)
artik12329-Dec-19 03:25 AM
Business development is not considered doing?
CrisF29-Dec-19 03:28 AM
Understand, and remember seeing you as a NN.
Would like to see how, who, what, etc. Not expecting big ideas like that to be done by one person.
Yes, business dev is not just ideas and thoughts though. It's also putting them into action by making a concrete plan, implementing those plans, etc.
I'm very curious on your ideas on implementation and am willing to put some time into this.(edited)
artik12329-Dec-19 03:30 AM
Let's first wait for jl response(edited)
CrisF29-Dec-19 03:31 AM
I saw that he, and others, have responded in the other channels where this was discussed.
jl777c29-Dec-19 05:54 AM
you put words into my mouth, as we do not want to have 100s of CC core devs, we want to make the reference implementations and show what is possible.
also there is nothing that prevents a solidity CC, other than the relatively large amount of work it would take
and i have nothing against such middleware
also, i will repeat that the marketing guys are working on getting consulting companies up to speed along with our training docs so that projects can hire a CC dev when they need one. realistically a funded project will need a spectrum of resources, including a CC dev (relatively small amount of work), GUI dev (more work), systems, etc. so i dont think the problem is the funded projects
Mylo29-Dec-19 06:01 AM
this is the key, a funded company that is producing a new service. they'll be looking to implement some customization. this funded company / start up will have maybe one or two coders that know what they are doing, will need to get up to speed or get assistance.
it's the same model parity uses with substrate. it's all a timing (when ICO was) & budget (bear market) related thing. all the pieces are in place, are still being built etc.
another 6-12 months, plenty more tech to build on & a flagship GUI trading network (atomicdex api) with the flagship security application (dpow) which offers an IoT solution with nSPV.
CrisF29-Dec-19 06:01 AM
Yes, it is clear that steps are being taken to this end.
The amount of docs and resources for developers and users have exploded over the last year!
Been doing what I can and am glad to find other things that I can do to maximize my usefulness.(edited)
Mylo29-Dec-19 06:02 AM
the stablecoin solution is another interesting fintech innovation for the ecosystem.
jl777c29-Dec-19 06:06 AM
any project would be able to launch their own algorithmic stablecoin, via commandline and no coding
maybe i am wrong, but that seems to be a unique thing
Mylo29-Dec-19 06:06 AM
to put into perspective the bear market
jl777c29-Dec-19 06:06 AM
and it is an example of bash scripts + existing CC being able to do what otherwise needs a lot of coding

CrisF29-Dec-19 06:10 AM
solidity CC
artik12329-Dec-19 06:10 AM
@CrisF If it would be on a virtual machine, with an account based contracts then yes.(edited)
CrisF29-Dec-19 06:11 AM
What would the first step in getting that done be?
Qtum is an open-sourced blockchain application platform. Qtum utilizes the UTXO model, solidity smart contracts, and proof-of-stake consensus to support a broad array of industries and use cases.

Genetic Algorithms
SEM6120 Assignment 1
What is a genetic algorithm?
- Example
- More formally:
- A form of evolutionary algorithm.
- Focus on search optimisation.
- Biologically inspired.
Terminology
- Genes represent changeable parts of the problem
- Chromosomes are a solution, encoded through a data structure of genes.
- Alleles are the different variants a gene has.
- Genotype is the encoded chromosome.
- Phenotype is the real-world value of a chromosome.
Crossover for Ordered Chromosomes
Some problems have genes which cannot be repeated within the chromosome.
"Normal" crossover will produce invalid solutions, so we needs some other
strategies.
Cycle Crossover
Sexual Crossover
- To future imitate real world genetics, some crossover schemes add genders
into the chromosomes.
- Just a limit on which chromosomes can crossover.
- Add selection pressures[1].
Multi-Objective Genetic Algorithm (MOGA)[2]
- Normal GAs would combine the fitness function to work out the fitness.
- MOGA uses a weighted some of the fitness functions.
- The weights are not fixed, but applied randomly at each selection.
References
[1] Sexual Selection with Competitive/Co-Operative Operators for Genetic
Algorithms — José Sánchez-Velazco and John A. Bullinaria
[2] MOGA: Multi-Objective Genetic Algorithms — Tadahiko Murata and
Hisao Ishibuchi.
Cycle Crossover - Detail
- Randomly choose point a
i
within the chromosomes.
- Do:
- Replace the allele from point
i
in P1
with the allele from point i
in
P2
.
i
is set to be the index of the current removed allele in P2
- While the current removed allele isn't the first removed one.
Cycle Crossover - Detail
- This keeps parts of the tour the same.
- Not as good as preserving parts of the tour as other algorithms
- Compare Order 1 crossover.
Sexual Crossover and Selection
- Generally sexual crossover is just a limiting factor on crossover.
- Recently, sexual characteristics have been used to enhance selection.
Co-operative Selection
- Males are selected with a normal selection scheme.
- Females are selected based on:
- Their co-operative fitness with their partner.
- Their age.
- The improvement in fitness between their child and its father.
Co-operative Selection
- Shown to have improvements, based on the TSP.
- Parallelisable (assuming the selection scheme used to select males is).
Multi-Objective Genetic Algorithms
- Trying to optimise two or more functions.
- Can't always just weight the functions;
Multi-Objective Genetic Algorithms
- Randomly weight the fitness functions to get provide more all-encompassing
results.
- Elite Preservation.

THEN fashioned for him the folk of Geats
firm on the earth a funeral-pile,
and hung it with helmets and harness of war
and breastplates bright, as the boon he asked;
and they laid amid it the mighty chieftain,
heroes mourning their master dear.
Then on the hill that hugest of balefires
the warriors wakened. Wood-smoke rose
black over blaze, and blent was the roar
of flame with weeping (the wind was still),
till the fire had broken the frame of bones,
hot at the heart.
Wailing her woe, the widow [footnote 1] old,
her hair upbound, for Beowulf's death
sung in her sorrow, and said full oft
she dreaded the doleful days to come,
deaths enow, and doom of battle,
and shame. — The smoke by the sky was devoured.
The folk of the Weders fashioned there
on the headland a barrow broad and high,
by ocean-farers far descried:
in ten days' time their toil had raised it,
the battle-brave's beacon. Round brands of the pyre
a wall they built, the worthiest ever
that wit could prompt in their wisest men.
They placed in the barrow that precious booty,
the rounds and the rings they had reft erewhile,
hardy heroes, from hoard in cave, —
trusting the ground with treasure of earls,
gold in the earth, where ever it lies
useless to men as of yore it was.
Then about that barrow the battle-keen rode,
atheling-born, a band of twelve,
lament to make, to mourn their king,
chant their dirge, and their chieftain honor.
They praised his earlship, his acts of prowess
worthily witnessed: and well it is
that men their master-friend mightily laud,
heartily love, when hence he goes
from life in the body forlorn away.
Thus made their mourning the men of Geatland,
for their hero's passing his hearth-companions:
quoth that of all the kings of earth,
of men he was mildest and most beloved,
to his kin the kindest, keenest for praise.
Footnotes
1. Nothing is said of Beowulf's wife in the poem, but Bugge surmises that Beowulf finally accepted Hygd's offer of kingdom and hoard, and, as was usual, took her into the bargain.

In cryptography, a preimage attack on cryptographic hash functions tries to find a message that has a specific hash value. 笔记：Hash算法的正常过程是这样的，“输入数据--> Hash算法 --> 输出数据”；而pre-image attack是逆向进行的，是从“输出数据”入手，希望找到相应的”输入数据“。它的着手点有两处，第一个着手点是”Hash算法“，从Hash算法的计算过程中找出破绽，从而实现逆向计算；第二个着手点是”输入数据“，分析输入数据的本身是不是有某种结构特征，从而发现规律，找到类似的输入数据。
A cryptographic hash function should resist attacks on its preimage (set of possible inputs). 笔记：一个合格的Hash算法，应该具备防御pre-image attack的能力。
In the context of attack, there are two types of preimage resistance:
These can be compared with a collision resistance, in which it is computationally infeasible to find any two distinct inputs x, x′ that hash to the same output, i.e., such that h(x) = h(x′). 笔记：与pre-image resistance和second pre-image resistance相似的一个概念是collision resistance
The relation between collision resistance, second preimage resistance and preimage resistance is rather subtle, and it depends on the formalization of the definition: Under certain conditions, collision resistance implies second-preimage resistance, but does not guarantee preimage resistance; Conversely, a second-preimage attack implies a collision attack. 笔记：这三个概念的差异很微妙


The West Brom transfer rumour that Baggies fans won't want to hear
Latest West Bromwich Albion transfer news | The Baggies defender is enjoying his breakthrough season at The Hawthorns but his current deal is due to expire at the end of the season
by Mark WakefieldWest Bromwich Albion will reportedly be will willing to sell defender Nathan Ferguson, if a new contract is not agreed.
The 19-year-old’s current deal at The Hawthorns expires at the end of the season, and has impressed in his breakthrough campaign with Albion .
Express & Star claim that a five-year deal has been offered to Ferguson, but is yet to put pen to paper on the extension.
The report adds that Albion will be forced into selling Ferguson in the January transfer window, should the teenager not commit to a new deal at The Hawthorns.
It has also been claimed that a number of clubs both in England and abroad are keeping tabs on the situation, with a view to a potential offer for the young defender.
Premier League duo Tottenham Hotspur and Crystal Palace have been linked with Ferguson, along with Serie A Champions Juventus and La Liga outfit Atletico Madrid.

Current Problems
- JavaScript Cold starts
- The performance of applications on the web platform is becoming increasingly bottlenecked by the startup (load) time. Large amounts of JavaScript code are required to create rich web experiences that we’ve become used to. When we look at the total size of JavaScript requested on mobile devices from HTTPArchive, we see that an average page loads 350KB of JavaScript, while 10% of pages go over the 1MB threshold. The rise of more complex applications can push these numbers even higher.
- As networks become faster, parsing and compilation of JavaScript could become the dominant factor. A 1MB JavaScript file will take an order of a 100 ms to parse on a modern desktop or high-end mobile device but can take over a second on an average phone (Moto G4). For example, in the case of news.google.com, it can range from 4s on a Pixel 2 to 28s on a low-end device.

For the fig-swirl: Melt butter over medium heat in a saucepan. Add brown sugar and stir to dissole. Halve all of the figs and toss in the saucepan with water and lemon juice. Cook over medium heat, stirring frequently, until you have a chunky-jammy mixture. Add salt with one or two stirs, set aside and let cool completely.
Ice cream: In a small pot over medium heat, combine milk, and granulated sugar until sugar is completely dissolved and the milk is just barely lukewarm. Whisk in the egg yolks. Set mixture in the fridge and wait until the fig mixture is cooled.
Using an ice cream machine, pour liquids into the frozen basin and process according to manufacturer instrctions,i.e., let spin and thicken for 20 minutes before adding mascarpone, fig jam mixture, and the nuts. Continue to process for +/- 10 minutes. Pour semi-frozen mixture into pyrex dish or glass tupperware. Freeze for at least two hours before serving.

1 I am a man who has seen misery under the rod of Yahweh's fury.
2 He has driven me away and caused me to walk in darkness rather than light.
3 Surely he has turned against me; he turns his hand against me all the day.
4 He has worn out my flesh and my skin; he has broken my bones.
5 He has built up siege works against me, and surrounded me with bitterness and hardship.
6 He has made me to live in dark places, like those long dead.
7 He has built a wall around me, and I cannot escape. He has made my shackles heavy.
8 Though I call out and scream for help, he shuts out my prayers.
9 He has blocked my path with walls of hewn stone; every way I take is crooked.
10 He is a bear waiting to ambush me, a lion in hiding.
11 He has turned aside my paths. He tears me apart and makes me desolate.
12 He has bent his bow and marked me as a target for an arrow.
13 He has sent the arrows of his quiver to enter into my kidneys.
14 I have become a laughingstock to all my people, the subject of their taunting song day by day.
15 He has filled me with bitterness and forced me to drink wormwood.
16 He has crushed my teeth with gravel; he has pushed me down into the dust.
17 You have removed peace from my life; I no longer remember any happiness.
18 So I said, "My endurance has perished, and my hope in Yahweh is gone."
19 I call to mind my affliction and my straying into wormwood and bitterness.
20 I certainly call it to mind, and I bow down within myself in despair.
21 But I call this to mind, and this is why I have hope:
22 It is by the covenant faithfulness of Yahweh that we are not destroyed, for his merciful actions have not come to an end.
23 His merciful actions occur afresh every morning; great is your faithfulness!
24 "Yahweh is my inheritance," I have said to myself, so I will hope in him.
25 Yahweh is good to the one who waits for him, to the life that seeks him.
26 It is good to wait in silence for the salvation of Yahweh.
27 It is good for a man that he bear the yoke in his youth.
28 Let him sit alone and silent, because Yahweh has laid it upon him.
29 Let him put his mouth in the dust, and perhaps there may be hope.
30 Let him give his cheek to the one striking him. Let him be filled full with disgrace,
31 for the Lord will not reject him forever!
32 For though he brings grief, he also shows compassion that comes out of the greatness of his covenant faithfulness.
33 For he does not oppress from his heart, or torment the sons of men.
34 To crush all the captives on earth under his foot,
35 to turn aside the justice of men before the face of the Most High,
36 to suppress a person in his cause—does not the Lord see?
37 Who is it that speaks and it happens when the Lord has not commanded it?
38 Do not both calamity and success come out of the mouth of the Most High?
39 How can any person alive complain? How can any man complain about the punishment for his sins?
40 Let us test and examine our ways, and turn again to Yahweh.
41 Let us lift up our hearts and our hands to God in the heavens and pray:
42 "We have transgressed and have rebelled against you, so you have not pardoned us.
43 You have covered yourself with anger and pursued us. You have slaughtered us, and you have not pitied us.
44 You have covered yourself with a cloud, so that no prayer can pass through.
45 You have made us castoffs and refuse among the peoples.
46 All our enemies have opened their mouth mockingly against us.
47 Fear of the pit has come upon us, desolation and crushing."
48 My eye runs down with streams of water because of the crushing of the daughter of my people.
49 My eyes flow out, and they do not stop, for there is no end to it
50 until Yahweh looks down and sees from heaven.
51 My eye brings severe pain to my life because of all the daughters of my city.
52 My enemies have relentlessly hunted me like a bird, without cause.
53 They have destroyed my life in a well and have placed a stone over me.
54 Waters flowed over my head; I said, "I have been cut off!"
55 I called on your name, Yahweh, out of the lowest pit.
56 You heard my voice when I said, "Do not hide your ear from my call for relief, from my cry for help."
57 You drew near on the day that I called on you; you told me, "Do not fear!"
58 Lord, you defended me when I was on trial for my life; you have saved my life!
59 Yahweh, you have seen their oppression of me. Judge my case justly.
60 You have seen all their acts of vengeance, all their plans against me.
61 You have heard their scorn, Yahweh, and all their plans regarding me.
62 You have heard the lips of those who rose up against me; you have heard their deep thoughts that are against me all day long.
63 Whether in their sitting or their rising up, look, Yahweh!

Penticton RCMP seeking public input to find suspect in poppy box thief
by Steve ArstadPenticton RCMP are investigating after a poppy box was stolen from a Penticton grocery store last week.
A man walked into Penticton Safeway on Nov. 10 around 4:30 p.m. and stole a poppy box full of donations after it was left temporarily unattended.
Police spokesperson Const. James Grandy said in a press release issued today, Nov. 20, video surveillance has been obtained and police are hoping the public can help identify the suspect.
Anyone with information about this incident is asked to contact Const. Ritcey of the Penticton RCMP at<PHONE_NUMBER>, quoting file 2019-19786, or call Crime Stoppers at 1-800-222-8477.


There are times where I wish I could go back, rewind what happened, and listen again. Daydreamers, you know what I’m talking about. Even though it’s not in the official pillars of Flipped Learning, a reason I hear people flipping their instruction is so kids can pause, rewind, and re-watch a portion of the instruction. It sounds powerful, and it gives a great visual of students working hard on their notes, but it may not be as helpful as it initially sounds.
A 2005 study focused on how students studied using video lectures. I know the technology in 2005 was far inferior to the on-demand video content we have today, but that particular point doesn’t really matter. What I want to focus on is the fact that there are some indications that pausing and rewinding content can be disruptive to the learning process (emphasis added).
Students tried to view an entire lecture in a single session; however, some discovered that pausing was necessary. All participants who interrupted viewing reported that pausing caused a serious problem which involved returning to the break point. Students reported that even though they returned to the precise point at which they stopped, they lost the context and didn’t immediately understand what followed. The following example illustrates this point:
“A pause in watching video is worse than a break in reading a book, because I felt that I have no place to return to. I lost context.”
This is just one example of a more poignant point I’m trying to make – don’t distill the benefits of your methods down to one idea or another. Look at your strategies holistically and be able to explain how they work together to your students’ advantage.
There were interesting counterpoints to the above example in the same article:
Navigating the video backward and forward was difficult and disadvantageous for some students, whereas others found it easy and advantageous. Some examples:
“…it wasn’t easy.  Rewinding is annoying.”
“…an advantage is that you can repeat something over and over, like I sometimes do when I read a book; however, I never did it. A few times I stopped and ran the CD-ROM backward and then played it again. It was easy.”
One research study does not a law make. However, the feedback from the students in this study is interesting. In addition to the findings about rewinding content, the authors sum the study up in an interesting way:
Our first finding is that most students tried to study from video as if it was a book; in other words,
these students attempted to transfer learning strategies from one medium to another.
The point is that we have to be careful about two things:
Repetition isn’t a bad thing – the methods we typically rely on for repetition aren’t so great. Here are some ideas for how to revisit ideas with your students:
Context is key! Put your students into situations where they’re forced to think back to previous work. This is similar to spiraling, but it’s more than just mentioning, “think back to when we did…” Planning is important as making contextual connections in your lessons will help students solidify their understanding.
Lastly, remember “getting it” isn’t the important part. Yes, we want our students to have multiple opportunities to get a concept, but that’s just step one. If they don’t understand an idea the first or second time through a video, a third or fourth time through may not help much. Don’t fall back on, “Have you watched it again?” Be sure to ask questions, see what they do understand, and then build out a plan from there.

A source-code getaway.
Let's explore a simple, perhaps contrived example of a change to a React component with setState, changing a boolean to reflect the display of a form.
Eric Saxman | 'Andrelton' - 2015.
Find me on GitHub | LinkedIn.
Example: this.setState({ showForm: true; });
Many functions are called throughout the course of enqueueing and making changes to the DOM. Perhaps the easiest way of following the series of function calls will be to have a strict understanding which variable caries points to the component and which variable carries the updated state.
For the purpose of this exercise, we'll ignore the callback process and focus solely on the state.
When equeueSetState is called within setState, this is the component, and partialState is the updated state we provided. In subsequent function calls, the component will be referred to as publicInstance.
getInternal... goes out to ReactInstanceMap to retrieve the internal representation of this public-facing stateful instance.
This internal representation is already carried on the component as the property _reactInternalInstance, ReactInstanceMap simply separates the key/value pair and returns the internal instance.
Finally, the internal representation of the component is added to a queue for a potential rerendering.
NOTE: Very little code has been removed. Most sections represented by elipses are error-handling messages which are not present in the minified version.
https://fb.me/react-0.13.3.js
ReactComponent.prototype.setState = function(partialState, callback) { ... ReactUpdateQueue.enqueueSetState(this, partialState); if (callback) { ReactUpdateQueue.enqueueCallback(this, callback); } }; }; var ReactUpdateQueue = { ... enqueueSetState: function(publicInstance, partialState) { var internalInstance = getInternalInstanceReadyForUpdate( publicInstance, 'setState' ); ... enqueueUpdate(internalInstance); }, ... }; function getInternalInstanceReadyForUpdate(publicInstance, callerName) { ... var internalInstance = ReactInstanceMap.get(publicInstance); ... return internalInstance; }; var ReactInstanceMap = { ... get: function(key) { return key._reactInternalInstance; }, ... }; function enqueueUpdate(component) { ... dirtyComponents.push(component); };
var dirtyComponents = []; ... function runBatchedUpdates(transaction) { var len = transaction.dirtyComponentsLength; ... dirtyComponents.sort(mountOrderComparator); for (var i = 0; i < len; i++) { var component = dirtyComponents[i]; ... ReactReconciler.performUpdateIfNecessary( component, transaction.reconcileTransaction ); }; }; var ReactReconciler = { ... performUpdateIfNecessary: function(transaction) { if (this._pendingElement != null) { ReactReconciler.receiveComponent( this, this._pendingElement || this._currentElement, transaction, this._context ); } }, ... receiveComponent: function(nextElement, transaction, nextContext) { var prevElement = this._currentElement; var prevContext = this._context; this._pendingElement = null; this.updateComponent( transaction, prevElement, nextElement, prevContext, nextContext ); }, ... };

DDATE(1) Emperor Norton User Command DDATE(1) NAME ddate - convert Gregorian dates to Discordian dates SYNOPSIS ddate [+format] [date] DESCRIPTION ddate prints the date in Discordian date format. If called with no arguments, ddate will get the current system date, con‐ vert this to the Discordian date format and print this on the standard output. Alternatively, a Gregorian date may be specified on the command line, in the form of a numerical day, month and year. If a format string is specified, the Discordian date will be printed in a format specified by the string. This mechanism works similarly to the format string mechanism of date(1), only almost completely differently. The fields are: %A Full name of the day of the week (i.e., Sweetmorn) %a Abbreviated name of the day of the week (i.e., SM) %B Full name of the season (i.e., Chaos) %b Abbreviated name of the season (i.e., Chs) %d Ordinal number of day in season (i.e., 23) %e Cardinal number of day in season (i.e., 23rd) %H Name of current Holyday, if any %N Magic code to prevent rest of format from being printed unless today is a Holyday. %n Newline %t Tab %X Number of days remaining until X-Day. (Not valid if the SubGenius options are not compiled in.) %{ %} Used to enclose the part of the string which is to be replaced with the words "St. Tib's Day" if the current day is St. Tib's Day. %. Try it and see. EXAMPLES % ddate Sweetmorn, Bureaucracy 42, 3161 YOLD % ddate +'Today is %{%A, the %e of %B%}, %Y. %N%nCelebrate %H' Today is Sweetmorn, the 42nd of Bureaucracy, 3161. % ddate +"It's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 26 9 1995 It's Prickle-Prickle, the 50th of Bureaucracy, 3161. Celebrate Bureflux % ddate +"Today's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 29 2 1996 Today's St. Tib's Day, 3162. BUGS ddate(1) will produce undefined behavior if asked to produce the date for St. Tib's day and its format string does not contain the St. Tib's Day delimiters %{ and %}. NOTE After `X-Day' passed without incident, the Church of the SubGenius declared that it had got the year upside down - X-Day is actually in 8661 AD rather than 1998 AD. Thus, the True X-Day is Cfn 40, 9827. AUTHOR Original program by Druel the Chaotic aka Jeremy Johnson<EMAIL_ADDRESS>Major rewrite by Lee H:. O:.

One of my favourite things to do is travel and experience new and different cultures. I plan to travel to as many places as I possibly can.
I have been lucky enough to have visited some incredibly beautiful places like Italy, France, Spain, Holland, Germany, Greece etc.
I've even been surprised with a hot air balloon ride over Segovia, Madrid- which I would HIGHLY recommend! Absolutely incredible experience
where I also got to meet and converse with very interesting people from all over the world.
Out of everywhere I've been so far, my two favourite places have to be Mykonos-Greece and Madrid-Spain.

module Genarray: sig .. end
type t('a, 'b, 'c);
Genarray.t
is the type of big arrays with variable
numbers of dimensions. Any number of dimensions between 1 and 16
is supported.
The three type parameters to Genarray.t
identify the array element
kind and layout, as follows:
'a
, is the OCaml type for accessing array
elements (float
, int
, int32
, int64
, nativeint
);'b
, is the actual kind of array elements
(float32_elt
, float64_elt
, int8_signed_elt
, int8_unsigned_elt
,
etc);'c
, identifies the array layout
(c_layout
or fortran_layout
).(float, float32_elt, fortran_layout) Genarray.t
is the type of generic big arrays containing 32-bit floats
in Fortran layout; reads and writes in this array use the
OCaml type float
.let create:
(Bigarray.kind('a, 'b), Bigarray.layout('c), array(int)) => t('a, 'b, 'c);
Genarray.create kind layout dimensions
returns a new big array
whose element kind is determined by the parameter kind
(one of
float32
, float64
, int8_signed
, etc) and whose layout is
determined by the parameter layout
(one of c_layout
or
fortran_layout
). The dimensions
parameter is an array of
integers that indicate the size of the big array in each dimension.
The length of dimensions
determines the number of dimensions
of the bigarray.
For instance, Genarray.create int32 c_layout [|4;6;8|]
returns a fresh big array of 32-bit integers, in C layout,
having three dimensions, the three dimensions being 4, 6 and 8
respectively.
Big arrays returned by Genarray.create
are not initialized:
the initial values of array elements is unspecified.
Genarray.create
raises Invalid_argument
if the number of dimensions
is not in the range 1 to 16 inclusive, or if one of the dimensions
is negative.
let num_dims: t('a, 'b, 'c) => int;
let dims: t('a, 'b, 'c) => array(int);
Genarray.dims a
returns all dimensions of the big array a
,
as an array of integers of length Genarray.num_dims a
.let nth_dim: (t('a, 'b, 'c), int) => int;
Genarray.nth_dim a n
returns the n
-th dimension of the
big array a
. The first dimension corresponds to n = 0
;
the second dimension corresponds to n = 1
; the last dimension,
to n = Genarray.num_dims a - 1
.
Raise Invalid_argument
if n
is less than 0 or greater or equal than
Genarray.num_dims a
.let kind: t('a, 'b, 'c) => Bigarray.kind('a, 'b);
let layout: t('a, 'b, 'c) => Bigarray.layout('c);
let get: (t('a, 'b, 'c), array(int)) => 'a;
Genarray.get a [|i1; ...; iN|]
returns the element of a
whose coordinates are i1
in the first dimension, i2
in
the second dimension, ..., iN
in the N
-th dimension.
If a
has C layout, the coordinates must be greater or equal than 0
and strictly less than the corresponding dimensions of a
.
If a
has Fortran layout, the coordinates must be greater or equal
than 1 and less or equal than the corresponding dimensions of a
.
Raise Invalid_argument
if the array a
does not have exactly N
dimensions, or if the coordinates are outside the array bounds.
If N > 3
, alternate syntax is provided: you can write
a.{i1, i2, ..., iN}
instead of Genarray.get a [|i1; ...; iN|]
.
(The syntax a.{...}
with one, two or three coordinates is
reserved for accessing one-, two- and three-dimensional arrays
as described below.)
let set: (t('a, 'b, 'c), array(int), 'a) => unit;
Genarray.set a [|i1; ...; iN|] v
stores the value v
in the
element of a
whose coordinates are i1
in the first dimension,
i2
in the second dimension, ..., iN
in the N
-th dimension.
The array a
must have exactly N
dimensions, and all coordinates
must lie inside the array bounds, as described for Genarray.get
;
otherwise, Invalid_argument
is raised.
If N > 3
, alternate syntax is provided: you can write
a.{i1, i2, ..., iN} <- v
instead of
Genarray.set a [|i1; ...; iN|] v
.
(The syntax a.{...} <- v
with one, two or three coordinates is
reserved for updating one-, two- and three-dimensional arrays
as described below.)
let sub_left:
(t('a, 'b, Bigarray.c_layout), int, int) => t('a, 'b, Bigarray.c_layout);
Genarray.sub_left a ofs len
returns a big array with the same number of dimensions as a
,
and the same dimensions as a
, except the first dimension,
which corresponds to the interval [ofs ... ofs + len - 1]
of the first dimension of a
. No copying of elements is
involved: the sub-array and the original array share the same
storage space. In other terms, the element at coordinates
[|i1; ...; iN|]
of the sub-array is identical to the
element at coordinates [|i1+ofs; ...; iN|]
of the original
array a
.
Genarray.sub_left
applies only to big arrays in C layout.
Raise Invalid_argument
if ofs
and len
do not designate
a valid sub-array of a
, that is, if ofs < 0
, or len < 0
,
or ofs + len > Genarray.nth_dim a 0
.
let sub_right:
(t('a, 'b, Bigarray.fortran_layout), int, int) =>
t('a, 'b, Bigarray.fortran_layout);
Genarray.sub_right a ofs len
returns a big array with the same number of dimensions as a
,
and the same dimensions as a
, except the last dimension,
which corresponds to the interval [ofs ... ofs + len - 1]
of the last dimension of a
. No copying of elements is
involved: the sub-array and the original array share the same
storage space. In other terms, the element at coordinates
[|i1; ...; iN|]
of the sub-array is identical to the
element at coordinates [|i1; ...; iN+ofs|]
of the original
array a
.
Genarray.sub_right
applies only to big arrays in Fortran layout.
Raise Invalid_argument
if ofs

in the original
array a
. No copying of elements is involved: the slice and
the original array share the same storage space.

let blit: (t('a, 'b, 'c), t('a, 'b, 'c)) => unit;
Genarray.blit src dst
copies all elements of src
into
dst
. Both arrays src
and dst
must have the same number of
dimensions and equal dimensions. Copying a sub-array of src
to a sub-array of dst
can be achieved by applying Genarray.blit
to sub-array or slices of src
and dst
.let fill: (t('a, 'b, 'c), 'a) => unit;
Genarray.fill a v
stores the value v
in all elements of
the big array a
. Setting only some elements of a
to v
can be achieved by applying Genarray.fill
to a sub-array
or a slice of a
.let map_file:
(
Unix.file_descr,
~pos: int64=?,
Bigarray.kind('a, 'b),
Bigarray.layout('c),
bool,
array(int)
) =>
t('a, 'b, 'c);
Genarray.map_file fd kind layout shared dims
returns a big array of kind kind
, layout layout
,
and dimensions as specified in dims
. The data contained in
this big array are the contents of the file referred to by
the file descriptor fd
(as opened previously with
Unix.openfile
, for example). The optional pos
parameter
is the byte offset in the file of the data being mapped;
it defaults to 0 (map from the beginning of the file).
If shared
is true
, all modifications performed on the array
are reflected in the file. This requires that fd
be opened
with write permissions. If shared
is false
, modifications
performed on the array are done in memory only, using
copy-on-write of the modified pages; the underlying file is not
affected.
Genarray.map_file
is much more efficient than reading
the whole file in a big array, modifying that big array,
and writing it afterwards.
To adjust automatically the dimensions of the big array to
the actual size of the file, the major dimension (that is,
the first dimension for an array with C layout, and the last
dimension for an array with Fortran layout) can be given as
-1
. Genarray.map_file
then determines the major dimension
from the size of the file. The file must contain an integral
number of sub-arrays as determined by the non-major dimensions,
otherwise Failure
is raised.
If all dimensions of the big array are given, the file size is
matched against the size of the big array. If the file is larger
than the big array, only the initial portion of the file is
mapped to the big array. If the file is smaller than the big
array, the file is automatically grown to the size of the big array.
This requires write permissions on fd
.
Array accesses are bounds-checked, but the bounds are determined by
the initial call to map_file
. Therefore, you should make sure no
other process modifies the mapped file while you're accessing it,
or a SIGBUS signal may be raised. This happens, for instance, if the
file is shrunk.
This function raises Sys_error
in the case of any errors from the
underlying system calls. Invalid_argument
or Failure
may be
raised in cases where argument validation fails.

I taught myself some HTML and CSS basics through work, books, and free online courses and enjoyed it enough to decide to take the plunge with Flatiron's Online Web Developer Program. I started in late January 2018 and I'm extremely excited to learn new concepts and languages!
