The fully coupled atmosphere-ocean general circulation model (AOGCM), Community Climate System Model version 3 (CCSM3) 37 is employed here. Both the atmospheric module (CAM3) and the land module (CLM3) were run at a horizontal resolution of T31 (3.75° × 3.75°), and both the ocean (POP1.4) and sea ice (CSIM5) modules at “gx3v5” (with 100 and 116 grid points in the zonal and meridional directions, respectively). In the vertical, the atmosphere and ocean were divided into 26 and 25 levels, respectively. In this version of CCSM3, dust loading in the atmosphere is prescribed. The model calculates only the shortwave radiative effect of the dust, omitting the longwave effect and the indirect effect 28, 34, 38. Most estimates show that the global-mean longwave effect is much smaller than the shortwave effect both at the surface 32 and at the top of atmosphere 34. The indirect effect of dust through its interaction with cloud (mainly on ice cloud 33, 39– 41) may be large for the present day climate locally, but there is few estimate of its global influence.
The MH control climate was obtained by running the model with MH orbital parameters (at 6 ka), set according to the PMIP2 MH benchmark experiment 42, while everything else, including Greenhouse gas concentrations and ozone, were prescribed the same as for PI. The only change for the EH control climate simulation relative to the MH climate simulation is the orbital parameters (from 6 ka to 9 ka). The climate effect of dust removal during the EH is assumed to be the same whether the remnant ice sheet is considered or not. This may not be a bad assumption because the orbital effect is larger than the effect of remnant ice sheet in CCSM3 2. The present-day dust distribution is prescribed, which was produced using an aerosol assimilation system 43 and released with CCSM3. The dust loading is mostly over northern Africa, Arabia, Iranian plateau and western India (Fig. 2a), and has the largest amplitude during boreal spring and summer (Supplementary Fig. 2). To test the effect of dust reduction on global surface temperature, the atmospheric dust loading is reduced uniformly by a factor of, 25%, 50%, 75% and 100% for the MH, and 50% and 100% for the EH. This uniform dust reduction is somewhat crude but is based on the following considerations: (1) there are both observational 44 and modeling 42, 45 evidence that climate was wetter not only in northern Africa during MH, but also over Arabia and western India; (2) the dust deposition rate in the tropical and northern Atlantic, the Arabia Sea and east Asia all showed some depression over the mid Holocene relative to the late Holocene 17; (3) the coupled dust and climate modeling could not provide consistent dust loading for the Holocene 17– 19; (4) the dust loading is much smaller over regions like Gobi desert, Australia and South America at least in the present day (Fig. 2a), decrease of which may not be climatically consequential.
The control and dust-reduction experiments for EH and MH are all initialized from the PI equilibrium climate state, and are run for 1000 years. Running the control and dust-reduction experiments in parallel allows early diagnosis of the dust effect and saves waiting time. It is found that the dust effect diagnosed around model year 400 and year 1000 has negligible difference. Sensitivity experiments show almost the same the results if the control experiment was run to equilibrium first and then initialize the dust-reduction experiment from this equilibrium state. Therefore, it is not necessary to run the experiments to equilibrium to diagnose the effect of dust, and experiments for non-100% reduction are run for 500 years. At that time, the surface temperature are drifting at rate of ~0.4 °C/1000 years for both the control and dust-reduction experiments. The last 50 years of data are used for analyses. The MH control experiment shows a global cooling of 0.5 °C from the PI of the same dust, within the range of the state of the art models in PMIP experiments (Supplementary Fig. 1).
The datasets generated during and/or analysed during the current study are available from the corresponding author on reasonable request.


FillArea()
Syntax
FillArea(x, y, BorderColor [, Color])Description
Fill an arbitrary area starting from x,y position until the BorderColor is encountered. This is useful for filling any kind of shape.
Parameters
x, y The location at which the filling should start. BorderColor The color which should be considered the border to stop the filling. If this parameter is set to -1 then the area defined by the color found at the (x,y) coordinates will be filled, and filling stops at any color that differs from the starting point.
On 32-bit images, the alpha channel is ignored when determining whether a pixel counts as a border pixel or not.Color (optional) The color to be used for filling the pixels. If this parameter is not specified, the default color set with FrontColor() will be used. This color can be in RGB or RGBA format.

München/Zoom, 11. November 2020
Lazer, D., Pentland, A., Adamic, L., Aral, S., Barabási, A.-L., Brewer, D., … Alstyne, M. V. (2009). Computational Social Science. Science, 323(5915), 721–723. https://doi.org/10.1126/science.1167742
Thoughts about an emerging field 10 years ago. How do you think things has developed since then?
“In the long run, the question will be whether academia should nurture computational social scientists, or teams of computationally literate social scientists and socially literate computer scientists.”
“This article considers the basic question of how and why the campaigns on the two sides differed in their content and framing.”
“Do new social media reinforce or subvert the logics of campaigning that existed beforehand?” (p. 372)
Sticks: “Sticks are mistakes made by the other side, which are then used to question that side’s competence and credibility.” (p. 376)
Stones: “Stones are identified as core arguments – both substantive and emotional – in an attempt to anchor debate and set agendas.” (p. 376)
Tweets collected weekly: Tweet content, time stamps, retweets, followers.
Does retweeting “...suggest it has an increased value for (…) individuals and scope to become viral, spreading out to an ever-wider set of users and thus creating opportunities to inform or sway voters.”?
Reliability of measure:
| Positive: | Negative: | |
|---|---|---|
| Substantial: | Argument for benefits of preferred outcome. | Argument against negative consequences of outcome not preferred. |
| Presentation of group/opponent: | Positive mention of own group. | Negative mention of other group. |
Could be considered a (very) simple kind of topic modelling?
“This article considers the basic question of how and why the campaigns on the two sides differed in their content and framing.”
“Do new social media reinforce or subvert the logics of campaigning that existed beforehand?” (p. 372)

Sanitation without sewers
Energy-efficient toilets can operate without a sewer system and treat waste on the spot. About 2.3 billion people don’t have good sanitation. The lack of proper toilets encourages people to dump fecal matter into nearby ponds and streams, spreading bacteria, viruses, and parasites that can cause diarrhea and cholera. Diarrhea causes one in nine child deaths worldwide. Now researchers are working to build a new kind of toilet that’s cheap enough for the developing world and can not only dispose of waste but treat it as well. In 2011 Bill Gates created what was essentially the X Prize in this area—the Reinvent the Toilet Challenge. Since the contest’s launch, several teams have put prototypes in the field. All process the waste locally, so there’s no need for large amounts of water to carry it to a distant treatment plant. Most of the prototypes are self-contained and don’t need sewers, but they look like traditional toilets housed in small buildings or storage containers. The NEWgenerator toilet, designed at the University of South Florida, filters out pollutants with an anaerobic membrane, which has pores smaller than bacteria and viruses. Another project, from Connecticut-based Biomass Controls, is a refinery the size of a shipping container; it heats the waste to produce a carbon-rich material that can, among other things, fertilize soil. One drawback is that the toilets don’t work at every scale. The Biomass Controls product, for example, is designed primarily for tens of thousands of users per day, which makes it less well suited for smaller villages. Another system, developed at Duke University, is meant to be used only by a few nearby homes. So the challenge now is to make these toilets cheaper and more adaptable to communities of different sizes. “It’s great to build one or two units,” says Daniel Yeh, an associate professor at the University of South Florida, who led the NEWgenerator team. “But to really have the technology impact the world, the only way to do that is mass-produce the units.” —Erin Winick

This site pulls its data to calculate the number of hours played from HowLongToBeat.com. This is great, but the caveat is that naming schemes aren't 100% consistent between what I pull from the Steam API and what HLTB stores. That means that for any games that don't have consistent names, it's largely a manual process to connect to the two naming schemes, so that we pull the correct times.
If you happen to see some games that are incorrect, you can now report them on your profile page. Simply check the box next to the game names of whatever you see is wrong, and then enter the reason on the following page. This will help a lot in identifying which games have issues that need to be fixed first.

When memory is allocated, the allocating function (such as malloc(), calloc(), etc.) returns a pointer. The type of this pointer depends on whether you are using an older K&R compiler or the newer ANSI type compiler. With the older compiler the type of the returned pointer is char, with the ANSI compiler it is void.
If you are using an older compiler, and you want to allocate memory for an array of integers you will have to cast the char pointer returned to an integer pointer. For example, to allocate space for 10 integers we might write:
int *iptr; iptr = (int *)malloc(10 * sizeof(int)); if (iptr == NULL) { .. ERROR ROUTINE GOES HERE .. }If you are using an ANSI compliant compiler, malloc() returns a void pointer and since a void pointer can be assigned to a pointer variable of any object type, the (int *) cast shown above is not needed. The array dimension can be determined at run time and is not needed at compile time. That is, the 10 above could be a variable read in from a data file or keyboard, or calculated based on some need, at run time.
Because of the equivalence between array and pointer notation, once iptr has been assigned as above, one can use the array notation. For example, one could write:
int k; for (k = 0; k < 10; k++) iptr[k] = 2;to set the values of all elements to 2.
Even with a reasonably good understanding of pointers and arrays, one place the newcomer to C is likely to stumble at first is in the dynamic allocation of multi-dimensional arrays. In general, we would like to be able to access elements of such arrays using array notation, not pointer notation, wherever possible. Depending on the application we may or may not know both dimensions at compile time. This leads to a variety of ways to go about our task.
As we have seen, when dynamically allocating a one dimensional array its dimension can be determined at run time. Now, when using dynamic allocation of higher order arrays, we never need to know the first dimension at compile time. Whether we need to know the higher dimensions depends on how we go about writing the code. Here I will discuss various methods of dynamically allocating room for 2 dimensional arrays of integers.
First we will consider cases where the 2nd dimension is known at compile time.
multi[row][col] = 1; *(*(multi + row) + col) = 1;It is also true that the following two notations generate the same code:
multi[row] *(multi + row)Since the one on the right must evaluate to a pointer, the array notation on the left must also evaluate to a pointer. In fact multi[0] will return a pointer to the first integer in the first row, multi[1] a pointer to the first integer of the second row, etc. Actually, multi[n] evaluates to a pointer to that array of integers that make up the n-th row of our 2 dimensional array. That is, multi can be thought of as an array of arrays and multi[n] as a pointer to the n-th array of this array of arrays. Here the word pointer is being used to represent an address value. While such usage is common in the literature, when reading such statements one must be careful to distinguish between the constant address of an array and a variable pointer which is a data object in itself.
Consider now:
--------------- Program 9.1 -------------------------------- /* Program 9.1 from PTRTUT10.HTM 6/13/97 */ #include <stdio.h> #include <stdlib.h> #define COLS 5 typedef int RowArray[COLS]; RowArray *rptr; int main(void) { int nrows = 10; int row, col; rptr = malloc(nrows * COLS * sizeof(int)); for (row = 0; row < nrows; row++) { for (col = 0; col < COLS; col++) { rptr[row][col] = 17; } } return 0; } ------------- End of Prog. 9.1 --------------------------------Here I have assumed an ANSI compiler so a cast on the void pointer returned by malloc() is not required. If you are using an older K&R compiler you will have to cast using:
rptr = (RowArray *)malloc(.... etc.Using this approach, rptr has all the characteristics of an array name name, (except that rptr is modifiable), and array notation may be used throughout the rest of the program. That also means that if you intend to write a function to modify the array contents, you must use COLS as a part of the formal parameter in that function, just as we did when discussing the passing of two dimensional arrays to a function.
int (*xptr)[COLS];the variable xptr will have all the same characteristics as the variable rptr in METHOD 1 above, and we need not use the typedef keyword. Here xptr is a pointer to an array of integers and the size of that array is given by the #defined COLS. The parenthesis placement makes the pointer notation predominate, even though the array notation has higher precedence. i.e. had we written
int *xptr[COLS];we would have defined xptr as an array of pointers holding the number of pointers equal to that #defined by COLS. That is not the same thing at all. However, arrays of pointers have their use in the dynamic allocation of two dimensional arrays, as will be seen in the next 2 methods.
-------------- Program 9.2 ------------------------------------ /* Program 9.2 from PTRTUT10.HTM 6/13/97 */ #include <stdio.h> #include <stdlib.h> int main(void) { int nrows = 5; /* Both nrows and ncols could be evaluated */ int ncols = 10; /* or read in at run time */ int row; int **rowptr; rowptr = malloc(nrows * sizeof(int *)); if (rowptr == NULL) { puts("\nFailure to allocate room for row pointers.\n"); exit(0); } printf("\n\n\nIndex Pointer(hex) Pointer(dec) Diff.(dec)"); for (row = 0; row < nrows; row++) { rowptr[row] = malloc(ncols * sizeof(int)); if (rowptr[row] == NULL) { printf("\nFailure to allocate for row[%d]\n",row); exit(0); } printf("\n%d %p %d", row, rowptr[row], rowptr[row]); if (row > 0) printf(" %d",(int)(rowptr[row] - rowptr[row-1])); } return 0; } --------------- End 9.2 ------------------------------------In the above code rowptr is a pointer to pointer to type int. In this case it points to the first element of an array of pointers to type int. Consider the number of calls to malloc():
To get the array of pointers 1 call To get space for the rows 5 calls ----- Total 6 callsIf you choose to use this approach note that while you can use the array notation to access individual elements of the array, e.g. rowptr[row][col] = 17;, it does not mean that the data in the "two dimensional array" is contiguous in memory.
You can, however, use the array notation just as if it were a continuous block of memory. For example, you can write:
rowptr[row][col] = 176;just as if rowptr were the name of a two dimensional array created at compile time. Of course row and col must be within the bounds of the array you have created, just as with an array created at compile time.
If you want to have a contiguous block of memory dedicated to the storage of the elements in the array you can do it as follows:
----------------- Program 9.3 ----------------------------------- /* Program 9.3 from PTRTUT10.HTM 6/13/97 */ #include <stdio.h> #include <stdlib.h> int main(void) { int **rptr; int *aptr; int *testptr; int k; int nrows = 5; /* Both nrows and ncols could be evaluated */ int ncols = 8; /* or read in at run time */ int row, col; /* we now allocate the memory for the array */ aptr = malloc(nrows * ncols * sizeof(int)); if (aptr == NULL) { puts("\nFailure to allocate room for the array"); exit(0); } /* next we allocate room for the pointers to the rows */ rptr = malloc(nrows * sizeof(int *)); if (rptr == NULL) { puts("\nFailure to allocate room for pointers"); exit(0); } /* and now we 'point' the pointers */ for (k = 0; k < nrows; k++) { rptr[k] = aptr + (k * ncols); } /* Now we illustrate how the row pointers are incremented */ printf("\n\nIllustrating how row pointers are incremented"); printf("\n\nIndex Pointer(hex) Diff.(dec)"); for (row = 0; row < nrows; row++) { printf("\n%d %p", row, rptr[row]); if (row > 0) printf(" %d",(rptr[row] - rptr[row-1])); } printf("\n\nAnd now we print out the array\n"); for (row = 0; row < nrows; row++) { for (col = 0; col < ncols; col++) { rptr[row][col] = row + col; printf("%d ", rptr[row][col]); } putchar('\n'); } puts("\n"); /* and here we illustrate that we are, in fact, dealing with a 2 dimensional array in a contiguous block of memory. */ printf("And now we demonstrate that they are contiguous in memory\n"); testptr = aptr; for (row = 0; row < nrows; row++) { for (col = 0; col < ncols; col++) { printf("%d ", *(testptr++)); } putchar('\n'); } return 0; } ------------- End Program 9.3 -----------------Consider again, the number of calls to malloc()
To get room for the array itself 1 call To get room for the array of ptrs 1 call ---- Total 2 callsNow, each call to malloc() creates additional space overhead since malloc() is generally implemented by the operating system forming a linked list which contains data concerning the size of the block. But, more importantly, with large arrays (several hundred rows) keeping track of what needs to be freed when the time comes can be more cumbersome. This, combined with the contiguousness of the data block that permits initialization to all zeroes using memset() would seem to make the second alternative the preferred one.
As a final example on multidimensional arrays we will illustrate the dynamic allocation of a three dimensional array. This example will illustrate one more thing to watch when doing this kind of allocation. For reasons cited above we will use the approach outlined in alternative two. Consider the following code:
------------------- Program 9.4 ------------------------------------- /* Program 9.4 from PTRTUT10.HTM 6/13/97 */ #include <stdio.h> #include <stdlib.h> #include <stddef.h> int X_DIM=16; int Y_DIM=5; int Z_DIM=3; int main(void) { char *space; char ***Arr3D; int y, z; ptrdiff_t diff; /* first we set aside space for the array itself */ space = malloc(X_DIM * Y_DIM * Z_DIM * sizeof(char)); /* next we allocate space of an array of pointers, each to eventually point to the first element of a 2 dimensional array of pointers to pointers */ Arr3D = malloc(Z_DIM * sizeof(char **)); /* and for each of these we assign a pointer to a newly allocated array of pointers to a row */ for (z = 0; z < Z_DIM; z++) { Arr3D[z] = malloc(Y_DIM * sizeof(char *)); /* and for each space in this array we put a pointer to the first element of each row in the array space originally allocated */ for (y = 0; y < Y_DIM; y++) { Arr3D[z][y] = space + (z*(X_DIM * Y_DIM) + y*X_DIM); } } /* And, now we check each address in our 3D array to see if the indexing of the Arr3d pointer leads through in a continuous manner */ for (z = 0; z < Z_DIM; z++) { printf("Location of array %d is %p\n", z, *Arr3D[z]); for ( y = 0; y < Y_DIM; y++) { printf(" Array %d and Row %d starts at %p", z, y, Arr3D[z][y]); diff = Arr3D[z][y] - space; printf(" diff = %d ",diff); printf(" z = %d y = %d\n", z, y); } } return 0; } ------------------- End of Prog. 9.4 ----------------------------If you have followed this tutorial up to this point you should have no problem deciphering the above on the basis of the comments alone. There are a couple of points that should be made however. Let's start with the line which reads:
Arr3D[z][y] = space + (z*(X_DIM * Y_DIM) + y*X_DIM);Note that here space is a character pointer, which is the same type as Arr3D[z][y]. It is important that when adding an integer, such as that obtained by evaluation of the expression (z*(X_DIM * Y_DIM) + y*X_DIM), to a pointer, the result is a new pointer value. And when assigning pointer values to pointer variables the data types of the value and variable must match.

Oklahoman business cover briefs for Nov. 23, 2019
OK rig count holds
Oklahoma’s rig count remained unchanged this week as the nationwide number of working rigs declined, Baker Hughes reported Friday.
This week's national working rig count is 803, off three for the week and off 276 from the 1,079 that were drilling a year ago.
In Oklahoma, the count remained at 52, compared to 144 a year ago. The number of rigs working in the Cana Woodford basin declined by one week-over-week, to 27.
The most active basins this week, Baker Hughes said, are the Permian in west Texas and southeast New Mexico at 405, the south Texas Eagle Ford at 60, the Haynesville at 53, the Williston at 51 and the Marcellus at 36.
Continental appoints new board member
Continental Resources appointed a long-time oil and gas executive to its board, the company announced this week. Tim Taylor, president of Phillips 66 from 2014 until he retired in 2017, began as a Continental director on Nov. 20.
Taylor also worked for Phillips 66 as its executive vice president of commercial, marketing, transportation and business development from 2012 until he was promoted to president.
He has more than 35 years of experience in the oil and gas industry, serving in various executive management positions in midstream and downstream businesses.
He holds a Bachelor of Science in Chemical Engineering from Kansas State University.
Harold Hamm, Continental Resources’ chairman and CEO, said Taylor’s extensive experience provides the company “a tremendous asset.”

René Magritte (1898–1967) was one of the most intriguing painters associated with Surrealism, but he did not fully find his voice until after breaking ties with the movement. This exhibition, the first to look exclusively at Magritte’s late career, examines his most important bodies of work from the 1940s through the 1960s, and shows how they marked a fundamental shift in painting from Modernism to our own time.

MISSION: IMPOSSIBLE A film review by Ife Hsu Copyright 1996 Ife Hsu
(Paramount Release 1996) Starring: Tom Cruise, Jon Voight, Jean Reno, Emmanuelle Beart (sp), etc. Director: Brian DePalma Running Time: 1:55h
(*** out ****)
Overview: Motion feature based on TV series about a covert team assigned to ultra-secret missions revolving espionage, theft, security bleaks, etc. Movie version focus on the demise of this team as it faces an unknown double-crossing agent who aims for personal gain/objectives. It is a cat-and-mouse chase as agents of the covert team try to capture invisible enemy while battling own agency who has diswowed their membership.
Brian DePalma's Mission Impossible is desperately trying to replace Twister as the summer blockbuster for 1996. Given recent string of disasters (Bonfire of Vanities, Raising Caan, etc.), DePalma tries his best to strenghten a somewhat predictable plot with hair-raising special effects and a variety of technical gadgets. But above all, this is Tom Cruise's show. As an actor, Cruise has proven that he can carry a movie, but he is also a co-producer. Finally, Paramount's marketing ploy has made this film as anticipated as Jurassic Park or possibly Batman (1989).
There are really three 'Mission Impossible' shows: Setup, Comeback, Survival-of-Fittest.
In the Setup, the team is assigned to gather irrefutable proof for the capture of an international spy trying to steal a secret list containing names of field agents. Without revealing the outcome, I will only say that this Mission Impossible has other predictments involving the Agency itself.
Comeback is the attempt from the agents to find a solution to the problems caused in the Setup. The solution requires another Mission Impossible. This sequence brings the best suspense moments in the movie. Suffice to say that Cruise does stretch his acting and body in this sequence.
As a conclusion, Survival-of-Fittest proves once again that plausibility is not a given in Hollywood. The infamous train sequence is truly awesome and eye-catching, and totally unbelievable. As Cruise goes to capture his invisible enemy, he defies the laws of Physics and Human Conditioning.
Two sad notes: The female protagonist (newcomer Emmanuelle Beart (sp)) shows very limited acting range. Her role was already small compared to Cruise, but she was easily dismissed even in key moments. The plot is rather predictable. Like its TV counterpart, clues are given out during the movie, but it took no genius to determine the identity of the secret agent as well as the Setup sequence. It is sad to say that the expression given by Ms. Beart revealed all the mistery at that time.
Despite plot weaknings and uneven acting, I do recommend this movie as a lighthearted summer diversion as it should be.

Need IoT in Your Projects ?
I can help with that!
You may have noticed the huge title up there with this catchy acronyme : IoT. Well, what is it then ?
The Internet of things (IoT) is the extension of Internet connectivity into physical devices and everyday objects. Embedded with electronics, Internet connectivity, and other forms of hardware (such as sensors), these devices can communicate and interact with others over the Internet, and they can be remotely monitored and controlled
Few examples:
It happens that I have been working in this domain mixing hardware, software and web technologies since 2014.
Most of my projects were focused around creating a custom physical device and connect it either to a local computer/smartphone or to a cloud application for data processing/presenting.
A typical application involves designing and implementing:
Naturally, a large variety of tools and programming languages are involved in this process. I try, as much as I can, to pick the right tool for the current job.
I have mainly used:
Also a long list of Framework, SDK, Vendors IPs, vendor hardware are used
along the way.
More information in the skills section.
The projects page gives a deeper overview of the kind of work I usualy do.
IoT, Cloud Applications and Embedded Systems are a true passion of mine. don't hesistate to contact me to have a chat.


1942 – Start of the Program
The official start of the nuclear program did not begin until later in 1942. In a top secret decree from the Kremlin on September 28, 1942. The Kremlin suggested that “the Academy of Sciences should present to the State Committee of Defense a report on the possibility for uranium bomb or uranium fuel construction by 1 April 1943.”
Lavrenti Beria (infamous for leading the NKVD, the secret police, during the years of Stalin’s gulags) led the program along with physicist Igor Kurchatov. Kurchatov is known as the “father of the Soviet bomb” and led the scientific research of both the atomic and hydrogen bombs. However, after the first nuclear test he came to realize their destructive power in a new way, and became an advocate for the peaceful use of nuclear technology.

Twelve killed in Slovakia bus crash
BRATISLAVA (Reuters) - A lorry carrying gravel collided with a passenger bus, killing 12 people in western Slovakia on Wednesday, the country’s deadliest road accident in a decade, police said.
The accident occurred in rainy weather on a winding two-lane road near the city of Nitra, 90 km (56 miles) east of the capital Bratislava.
The truck was probably overloaded and wobbled, causing it to strike the bus on its side, Interior Minister Denisa Sakova told reporters as she headed to the site of the accident.
The bus then crashed into a ditch, with several people trapped underneath, she added.
The dead included four high school students.
Prime Minister Peter Pellegrini said in a statement he would end an official visit to Cyprus a day early to return to Slovakia and visit the site of the accident as well as the injured in nearby hospitals.

"When Brendan Met Trudy"
Brendan (Peter McDonald) is a Dublin high school teacher that loves music and movies, but hates teaching. When an extraordinary young woman named Trudy (Flora Montgomery) enters his life, he soon learns that there is more to living than Bogart and Brahms in "When Brendan Met Trudy."
The movie begins a la "Sunset Boulevard" with a body lying motionless in the gutter and a voice over explaining how he, Brendan, could arrive at such a nadir of life. As the story unfolds and more film references are mentioned and shown, we begin to understand that our hero is a tormented individual who is in desperate need of a change. His profession, teaching history and English at a Dublin high school, is unfulfilling, to say the least, and he seeks solace in his movies and his passion for song. This changes when Trudy enters the picture.
Trudy, Brendan learns, is a professional burglar and he, at first, is energized by the excitement of her crimes.  Brendan succumbs to family pressure and, soon after, he and Trudy are no longer an item. This is when he ends up in the gutter, shown in the beginning of the film, pretending to have been hit by a car in a vain cry for sympathy from Trudy. It takes an act of selfless bravery, later, by Brendan to impress Trudy and she agrees to take him back - if he helps her rob Nuala's home. The excitement of the deed drives Brendan to an even grander criminal plan - steal all of the hated computers from his school. But, things go awry and Trudy ends up in jail, shielding Brendan from arrest.
When Trudy is sentenced to two years in prison, Brendan mopes around, guilt-ridden and lonely over his loss of love. Even the heroes in his movies, his only comfort in the past, seem to mock him for letting the love of his life take the rap for him. He musters the courage to visit Trudy in prison and finds she has forgiven him. He unabashedly breaks out in a song that is both joy and redemption.
"When Brendan Met Trudy" is a nice idea for a film, but is less than it could be in the hands of first time feature director Kieron J. Walsh. The helmer hales from advertising and TV and it shows in the two-dimensional nature of the story and its protagonists. The tale focuses on Brendan and his passion for film and music is an integral part of his makeup. Peter McDonald doesn't take us far below the surface of the feckless Brendan, but the offbeat love story, music and film references are entertaining.
Flora Montgomery has the harder role as the self-assured, criminally minded Trudy. Her toughness opposite Brendan's milquetoast character is supposed to be a turning of the tables with the couple reversing conventional roles of tough guy, subservient gal. Trudy is too bubbly to come across as a tough-as-nails thief, but Montgomery does her best to breathe life into her role.
There is little going on to distract the viewer from the central story. Wacky and weird family members make up the background, but they, too, fail to come across as real people, though Brendan's speak-her-mind mom (Marie Mullen) gets some shock value out of her foul-mouthed judgements.
"When Brendan Met Trudy" tries to be a romantic comedy with the leads reversing conventional roles. There isn't a firm enough hand behind the camera to control the bland script by Roddy Doyle. As such, it moves along OK and has some kitschy film references with snippets of such classics as "The Quiet Man," "Africa Queen," "The Producers" and more but fails to satisfy the film buff in me. I give it a C.

The Economics of UI
23 Dec 2014(and What To Do About It)
Cost at scale
Software is famous for having marginal cost of essentially zero (the marginal cost is the cost of producing one more unit after the up-front cost, like building a factory, has been paid). This has big implications:
- a natural winner-take-all dynamics of markets
- venture capital ecosystem works
- open source is economically possible
Note: If you believe software is eating the world, this has interesting implications about the way the world of atoms is going to change soon. With software becoming a bigger component of physical goods and services, the fixed cost component to them is going to increase and the marginal cost is going to decrease. This means we might start to see some of the software-world dynamics (winner-take-all, venture capital, maybe even open source) in the physical economics as well. Uber and Tesla may be just precursors to a larger trend.
UI
Unlike the rest of the software, user interface has substantial marginal cost. An interface has two sides, UI has a software and a human side, each having different cost characteristics:
- The software side has large fixed cost to build, and zero marginal cost.
- The human side is the cost to adapt your users' brains to the way the software side of your UI works. The up-front cost here is e.g. the cost of creating the user manual, the marginal cost is training, support, or hidden in the smaller viral coefficient of your consumer app.
This understanding allows you to make decisions if and when to invest more in the software side of good UI, in order to reduce the marginal cost on the human side. It also means having a minimal UI is a good thing all else being equal.
Modeling a domain
Typical software models a part of the world with a set of hard rules. The user manipulates this formal model directly applying these rules via the user interface. Secondary effects from user actions are inferred by software and reflected in the model.
For example, in word processing, you get to manipulate text at higher level (type and edit text, apply formatting), with software inferring low level details (line breaks at page width, text flow around images, repeating header/footer etc). The computer maintains a model of text and applies deterministic operations on it. The model is fully transparent to the user, in fact he needs to understand it in order to use the software. After almost 40 years evolution and integration in the mainstream writing culture, the basic operations (typing and editing, line breaks, bold/italic/font/size formatting) feel natural. More complex things like maintaining consistent styling in a document are harder.
How to make minimal UI
One way to make UI (or software) more useful is to have a richer formal model that infers and silently does many useful things: like a spreadsheet does formula recalculation, or like databases utilize indices and nontrivial plan optimizations to execute queries. Unfortunately, good formal models are few and far between.
When a nice formal theory of the domain is not available, you can still fake it by inferring side effects with a predictive model, or machine learning. For example, a word processing program might try to infer what is the consistent styling that the user wants and apply it. A good UI might be one that hides part of the internally used model and asks the user to provide only examples of what he wants done. If the inference is good enough, that simplifies the user's mental model, so it reduces the marginal cost of your software.

Tanjung Piai early voter turnout 82pc at 1pm
PONTIAN, Nov 12 — Early voting in the Tanjung Piai parliamentary by-election has recorded a voter turnout of 82 per cent as of 1pm today.
Voting is being held at Bangunan Perkep at the Pontian district police headquarters here from 8am to 5pm.
Two polling streams were opened by the Election Commission (EC), for the Kukup and Pekan Nanas state constituencies, for 280 police officers and rank-and-file personnel to cast their ballots.
However, the Pekan Nanas stream was officially closed at 1pm while voting is still going on at the Kukup stream.
The 280 eligible voters include 210 personnel serving in Kukup and 18 in Pekan Nanas, the two state constituencies which make up the Tanjung Piai parliamentary seat.
A total of 38 voters are serving outside the district while 14 have retired from service.
A Bernama check showed that voting was proceeding smoothly amid good weather and that 10 police personnel have been deployed to maintain law and order.
The voting process was being conducted under the watchful eyes of EC observers and agents of the candidates.
Five of the six candidates also visited the polling centre, with Barisan Nasional’s (BN) Datuk Seri Dr Wee Jeck Seng being the first to arrive, just minutes before it was opened at 8am.
He was followed by Gerakan’s Wendy Subramaniam at 8.03am, Pakatan Harapan’s (PH) Karmaine Sardini at 8.20am, independent candidate Faridah Aryani Abd Ghaffar at 10.10am and Berjasa’s Datuk Dr Badrulhisham Abdul Aziz at 10.15am. Another independent candidate, Dr Ang Chuan Lock, has yet to turn up at the polling centre.
The Tanjung Piai by-election is the ninth to be held after the 14th general election on May 9, 2018, with the first being the Sungai Kandis state by-election in Selangor on Aug 4 last year.
The Tanjung Piai by-election was called following the death of incumbent MP Datuk Dr Md Farid Md Rafik, 42, of PH on Sept 21 due to heart complications. Polling is on Saturday. — Bernama

amount of elapsed/CPU time used (depending on OS)
Returns an approximation of the amount in seconds of CPU time used by the program.
formats a date/time string
Returns a string or a table containing date and time, formatted according to the given string format.
If the time argument is present, this is the time to be formatted (see the os.time function for a description of this value). Otherwise, date formats the current time.
If format starts with '!', then the date is formatted in Coordinated Universal Time. After this optional character, if format is the string "*t", then date returns a table with the following fields: year (four digits), month (1--12), day (1--31), hour (0--23), min (0--59), sec (0--61), wday (weekday, Sunday is 1), yday (day of the year), and isdst (daylight saving flag, a boolean).
If format is not "*t", then date returns the date as a string, formatted according to the same rules as the C function strftime.
When called without arguments,
date returns a reasonable date and time representation that depends on
the host system and on the current locale
(that is, os.date()
is equivalent to os.date("%c")
).
[format]
[time]
calculates a time difference in seconds
Returns the number of seconds from time t1 to time t2. In POSIX, Windows, and some other systems, this value is exactly t2-t1.
t2
t1
executes an operating system command
This function is equivalent to the C function system. It passes command to be executed by an operating system shell. It returns a status code, which is system-dependent. If command is absent, then it returns nonzero if a shell is available and zero otherwise.
[command]
attempts to terminate the process
Calls the C function exit, with an optional code, to terminate the host program. The default value for code is the success code.
Calling os.exit will do a hard exit which will not run the engine shutdown code. This may cause crashes on exit.
The recommended way to terminate your game is by using the exit message which does a graceful shutdown.
msg.post("@system:", "exit", {code = 0})
[code]
returns an operating system environment variable
Returns the value of the process environment variable varname, or nil if the variable is not defined.
varname
deletes a file
Deletes the file or directory with the given name. Directories must be empty to be removed. If this function fails, it returns nil, plus a string describing the error.
filename
renames a file
Renames file or directory named oldname to newname. If this function fails, it returns nil, plus a string describing the error.
oldname
newname
sets the current locale to the supplied locale
Sets the current locale of the program.
locale is a string specifying a locale;
category is an optional string describing which category to change:
"all"
, "collate"
, "ctype"
,
"monetary"
, "numeric"
, or "time"
;
the default category is "all"
.
The function returns the name of the new locale,
or nil if the request cannot be honored.
If locale is the empty string, the current locale is set to an implementation-defined native locale. If locale is the string "C", the current locale is set to the standard C locale.
When called with nil as the first argument, this function only returns the name of the current locale for the given category.
locale
[category]
returns the current time or calculates the time in seconds from a table
Returns the current time when called without arguments, or a time representing the date and time specified by the given table. This table must have fields year, month, and day, and may have fields hour, min, sec, and isdst (for a description of these fields, see the os.date function).
The returned value is a number, whose meaning depends on your system. In POSIX, Windows, and some other systems, this number counts the number of seconds since some given start time (the "epoch"). In other systems, the meaning is not specified, and the number returned by time can be used only as an argument to date and difftime.
[table]
returns a name for a temporary file
Returns a string with a file name that can be used for a temporary file. The file must be explicitly opened before its use and explicitly removed when no longer needed.
On some systems (POSIX), this function also creates a file with that name, to avoid security risks. (Someone else might create the file with wrong permissions in the time between getting the name and creating the file.) You still have to open the file to use it and to remove it (even if you do not use it).
When possible, you may prefer to use io.tmpfile, which automatically removes the file when the program ends.

Sweeten Your JavaScript
Sweet.js brings the hygienic macros of languages like Scheme and Rust to JavaScript. Macros allow you to sweeten the syntax of JavaScript and craft the language you’ve always wanted.
Do you want to use class syntax but don’t want to wait for ES6? Add them yourself with just a couple lines of code!
// Define the class macro here...
macro class {
rule {
$className {
constructor $cparams $cbody
$($mname $mparams $mbody) ...
}
} => {
function $className $cparams $cbody
$($className.prototype.$mname
= function $mname $mparams $mbody; ) ...
}
}
// An now classes are in JavaScript!
class Person {
constructor(name) {
this.name = name;
}
say(msg) {
console.log(this.name + " says: " + msg);
}
}
var bob = new Person("Bob");
bob.say("Macros are sweet!");
To get a better sense of what macros can do, check out some example macros or play around with macros in the online editor.
Getting sweet.js
Install the sweet.js compiler via npm:
$ npm install -g sweet.js

Getting Started
You can think of macros as functions that work on syntax. Much like a normal function you write a macro definition and then later invoke the macro with a syntax argument to produce new syntax. Running sweet.js code through the compiler will expand all macros and produce pure JavaScript that can be run in any JS environment.
Sweet.js provides two ways to define a macro: the simpler pattern-based rule macros and the more powerful procedural case macros (if you are familiar with Scheme or Racket these correspond to syntax-rules
and syntax-case
).
Pattern-Based Macros – Macros Rule!
Rule macros work by matching a syntax pattern and generating new syntax based on a template.
To define a macro sweet.js provides a new macro
keyword that looks something like this:
macro <name> {
rule { <pattern> } => { <template> }
}
For example, here’s a really simple identity macro that just expands to its syntax argument:
macro id {
rule {
// after the macro name, match:
// (1) a open paren
// (2) a single token and bind it to `$x`
// (3) a close paren
($x)
} => {
// just return the token that is bound to `$x`
$x
}
}
We can then invoke id
with:
id (42)
// --> expands to
42
A pattern that begins with $
matches any token and binds it to that name in the template while everything else matches literally.
Note that a single token includes matched delimiters not just numbers and identifiers. For example, an array with all of its elements counts as one token:
id ([1, 2, 3])
// --> expands to
[1, 2, 3]
Hygiene – Keeping it clean
To make things slightly more interesting, let’s say we want to write a macro that swaps the values stored in two variables.
macro swap {
rule { {$a <=> $b} } => {
var tmp = $a;
$a = $b;
$b = tmp;
}
}
var a = 10;
var b = 20;
swap {a <=> b}
After running this through sweet.js we get the expanded code:
var a$1 = 10;
var b$2 = 20;
var tmp$3 = a$1;
a$1 = b$2;
b$2 = tmp$3;
As you can see, the variables names have been changed with a $n
postfix. This is hygiene at work. One of the critical features of sweet.js is protecting macros from unintentionally binding or capturing variables they weren’t supposed to. This is called hygiene and to enforce hygiene sweet.js must carefully rename all variables.
If sweet.js did not protect hygiene a naive expansion would do the wrong thing:
var tmp = 10;
var b = 20;
swap {tmp <=> b}
// --> naive expansion
var tmp = 10;
var b = 20;
var tmp = tmp;
tmp = b;
b = tmp;
But since sweet.js protects hygiene, all variable names are correctly renamed:
var tmp = 10;
var b = 20;
swap {tmp <=> b}
// --> hygienic expansion
var tmp$1 = 10;
var b$2 = 20;
var tmp$3 = tmp$1;
tmp$3 = b$2;
b$2 = tmp$1;
In the cases where you want to intentionally break hygiene you can use the procedural case macros described in the next section.
Patterns and Macros - A match made in heaven
A pattern name can be restricted to a particular parse class by using $name:class
in which case rather than matching a token the pattern matches all the tokens matched by the class.
macro m {
rule { ($x:expr) } => {
$x
}
}
m (2 + 5 * 10)
// --> expands to
2 + 5 * 10
The parse classes currently supported are:
expr
– matches an expressionident
– matches an identifierlit
– matches a literal
Repeated patterns can be matched with the ...
syntax.
macro m {
rule { ($x ...) } => {
// ...
}
}
m (1 2 3 4)
A repeated pattern with a separator between each item can be matched by adding (,)
between ...
and the pattern being repeated.
macro m {
rule { ($x (,) ...) } => {
[$x (,) ...]
}
}
m (1, 2, 3, 4)
Repeated groups of patterns can be matched using $()
.
macro m {
rule { ( $($id:ident = $val:expr) (,) ...) } => {
$(var $id = $val;) ...
}
}
m (x = 10, y = 2+10)
Macros can have multiple rules.
macro m {
rule { ($x:lit) } => { $x }
rule { ($x:lit, $y:lit) } => { [$x, $y] }
}
m (1);
m (1, 2);
Rules are matched in-order and the first one to match the pattern will be used.
And macros can be recursively defined:
macro m {
rule { ($base) } => { [$base] }
rule { ($head $tail ...) } => { [$head, m ($tail ...)] }
}
m (1 2 3 4 5) // --> [1, [2, [3, [4, [5]]]]]
Procedural Macros – Just in Case
Sweet.js also provides a more powerful way to define macros: case macros. Case macros allow you to manipulate syntax using the full power of JavaScript. Case macros look like this:
macro <name> {
case { <pattern> } => { <body> }
}
Case macros look similar to rule macros with a few important differences. First, the patterns also match the macro name instead of just the syntax that comes after it:
macro m {
case { $name $x } => { ... }
}
m 42 // `$name` will be bound to the `m` token
// in the macro body
Most of the time you won’t need to match the name and can use the wildcard _
pattern (which matches any token but doesn’t bind it to a name) to ignore it:
macro m {
case { _ $x } => { ... }
}
The other difference from rule macros is that the body of a macro contains a mixture of templates and normal JavaScript that can create and manipulate syntax. For example, here’s the identity macro defined with a case macro:
macro id {
case {_ $x } => {
return #{ $x }
}
}
Templates are now created with the #{...}
form (which is technically shorthand for syntax {...}
). The #{...}
form creates an array of syntax objects using any pattern bindings that are in scope (i.e. were matched by the pattern).
Syntax objects are the representation of tokens that sweet.js uses to keep track of lexical context (which is used to maintain hygiene). They can be created with templates (#{}
) but you can also create individual syntax objects using the lexical context of an existing syntax object:
macro m {
case {_ $x } => {
var y = makeValue(42, #{$x});
return [y]
}
}
m foo
// --> expands to
42
Sweet.js provides the following functions to create syntax objects:
makeValue(val, stx)
–val
can be aboolean
,number
,string
, ornull
/undefined
makeRegex(pattern, flags, stx)
–pattern
is the string representaiton of the regex pattern andflags
is the string representation of the regex flagsmakeIdent(val, stx)
–val
is a string representing an identifiermakePunc(val, stx)
–val
is a string representing a punctuation (e.g.=
,,
,>
, etc.)makeDelim(val, inner, stx)
–val
represents which delimiter to make and can be either"()"
,"[]"
, or"{}"
andinner
is an array of syntax objects for all of the tokens inside the delimiter.
(These functions broadly correspond to the Scheme/Racket function datum->syntax
)
If you want strip a syntax object of its lexical context and get directly at the token you can use unwrapSyntax(stx)
(corresponding to Scheme’s syntax-e
).
When using these functions to create new syntax objects it is convenient to refer to them in #{}
templates. To do this sweet.js provides the letstx
macro that binds syntax objects to pattern variables:
macro m {
case {_ $x } => {
var y = makeValue(42, #{$x});
letstx $y = [y], $z = [makeValue(2, #{$x})];
return #{$x + $y - $z}
}
}
m 1
// --> expands to
1 + 42 - 2
Getting Dirty – Breaking Hygiene
Sometimes you really do need to break the wonderful protections provided by hygiene. Breaking hygiene is usually a bad idea but sweet.js won’t judge.
Breaking hygiene is done by stealing the lexical context from syntax objects in the “right place”. To clarify, consider aif
the anaphoric if macro that binds its condition to the identifier it
in the body.
var it = "foo";
long.obj.path = [1, 2, 3];
aif (long.obj.path) {
console.log(it);
}
// logs: [1, 2, 3]
This is a violation of hygiene because normally it
should be bound to the surrounding environment ("foo"
in the example above) but aif
wants to capture it
. To do this we can create an it
binding in the macro that has the lexical context associated with the surrounding environment. The lexical context we want is actually found on the aif
macro name itself. So we just need to create a new it
binding using the lexical context of aif
:
macro aif {
case {
// bind the macro name to `$aif_name`
$aif_name
($cond ...) {$body ...}
} => {
// make a new `it` identifier using the lexical context
// from `$aif_name`
var it = makeIdent("it", #{$aif_name});
letstx $it = [it];
return #{
// create an IIFE that binds `$cond` to `$it`
(function ($it) {
if ($cond ...) {
// all `it` identifiers in `$body` will now
// be bound to `$it`
$body ...
}
})($cond ...);
}
}
}
Let it be…less recursive
Sometimes you don’t want a macro to recursively call itself. For example, say you want to override function
to add some logging information before the rest of the function executes:
macro function {
case {_ $name ($params ...) { $body ...} } => {
return #{
function $name ($params ...) {
console.log("Imma let you finish...");
$body ...
}
}
}
}
If you tried to run this through the compiler it will loop forever since the function
identifier in the macro expansion is bound to the function
macro. To prevent this you can use the let
macro binding form:
let function = macro {
case {_ $name ($params ...) { $body ...} } => {
return #{
function $name ($params ...) {
console.log("Imma let you finish...");
$body ...
}
}
}
}
This binds function
to the macro in the rest of the code but not in the body of the function
macro.
Macros with Lookbehind – Watch Your Back
Sweet.js also lets you match on previous syntax using infix
rules. Use a vertical bar (|
) to separate your left-hand-side from your right-hand-side.
macro unless {
rule infix { return $value:expr | $guard:expr } => {
if (!($guard)) {
return $value;
}
}
}
function foo(x) {
return true unless x > 42;
return false;
}
You can use the infix
keyword with procedural macros, too. The macro name is just the first token on the right-hand-side.
macro m {
case infix { $lhs | $name $rhs } => { ... }
}
Infix rules can be mixed and matched with normal rules:
macro m {
rule infix { $lhs | $rhs } => { ... }
rule { $rhs } => { ... }
}
You can even leave off the right-hand-side for a postfix macro:
macro m {
rule infix { $lhs | } => { ... }
}
Sweet.js does its best to keep you from clobbering previous syntax.
macro m {
rule infix { ($args ...) | $call:expr } => {
$call($args ...)
}
}
(42) m foo; // This works
bar(42) m foo; // This is a match error
The second example fails to match because you’d be splitting the good function call on the left-hand-side in half. The result would have been nonsense, giving you a nasty parse error.

Asynchronous execution with hpx::async
and actions: Fibonacci¶
This example extends the previous example by
introducing actions: functions that can be run remotely. In this
example, however, we will still only run the action locally. The mechanism to
execute actions stays the same: hpx::async
. Later
examples will demonstrate running actions on remote localities
(e.g. Remote execution with actions: Hello world).
Setup¶
The source code for this example can be found here:
fibonacci.cpp
.
To compile this program, go to your HPX build directory (see HPX build system for information on configuring and building HPX) and enter:
make examples.quickstart.fibonacci
To run the program type:
./bin/fibonacci
This should print (time should be approximate):
fibonacci(10) == 55
elapsed time: 0.00186288 [s]
This run used the default settings, which calculate the tenth element of the
Fibonacci sequence. To declare which Fibonacci value you want to calculate, use
the --n-value
option. Additionally you can use the --hpx:threads
option to declare how many OS-threads you wish to use when running the program.
For instance, running:
./bin/fibonacci --n-value 20 --hpx:threads 4
Will yield:
fibonacci(20) == 6765
elapsed time: 0.233827 [s]
Walkthrough¶
The code needed to initialize the HPX runtime is the same as in the previous example:
int main(int argc, char* argv[])
{
// Configure application-specific options
hpx::program_options::options_description
desc_commandline("Usage: " HPX_APPLICATION_STRING " [options]");
desc_commandline.add_options()
( "n-value",
hpx::program_options::value<std::uint64_t>()->default_value(10),
"n value for the Fibonacci function")
;
// Initialize and run HPX
return hpx::init(desc_commandline, argc, argv);
}
The hpx::init
function in main()
starts the runtime system, and
invokes hpx_main()
as the first HPX-thread. The command line option
--n-value
is read in, a timer
(hpx::util::high_resolution_timer
) is set up to record the time it
takes to do the computation, the fibonacci
action is invoked
synchronously, and the answer is printed out.
int hpx_main(hpx::program_options::variables_map& vm)
{
// extract command line argument, i.e. fib(N)
std::uint64_t n = vm["n-value"].as<std::uint64_t>();
{
// Keep track of the time required to execute.
hpx::util::high_resolution_timer t;
// Wait for fib() to return the value
fibonacci_action fib;
std::uint64_t r = fib(hpx::find_here(), n);
char const* fmt = "fibonacci({1}) == {2}\nelapsed time: {3} [s]\n";
hpx::util::format_to(std::cout, fmt, n, r, t.elapsed());
}
return hpx::finalize(); // Handles HPX shutdown
}
Upon a closer look we see that we’ve created a std::uint64_t
to store the
result of invoking our fibonacci_action
fib
. This action will
launch synchronously (as the work done inside of the action will be
asynchronous itself) and return the result of the Fibonacci sequence. But wait,
what is an action? And what is this fibonacci_action
? For starters,
an action is a wrapper for a function. By wrapping functions, HPX can
send packets of work to different processing units. These vehicles allow users
to calculate work now, later, or on certain nodes. The first argument to our
action is the location where the action should be run. In this
case, we just want to run the action on the machine that we are
currently on, so we use hpx::find_here
. To
further understand this we turn to the code to find where fibonacci_action
was defined:
// forward declaration of the Fibonacci function
std::uint64_t fibonacci(std::uint64_t n);
// This is to generate the required boilerplate we need for the remote
// invocation to work.
HPX_PLAIN_ACTION(fibonacci, fibonacci_action);
A plain action is the most basic form of action. Plain
actions wrap simple global functions which are not associated with any
particular object (we will discuss other types of actions in
Components and actions: Accumulator). In this block of code the function fibonacci()
is declared. After the declaration, the function is wrapped in an action
in the declaration HPX_PLAIN_ACTION
. This function takes two
arguments: the name of the function that is to be wrapped and the name of the
action that you are creating.
This picture should now start making sense. The function fibonacci()
is
wrapped in an action fibonacci_action
, which was run synchronously
but created asynchronous work, then returns a std::uint64_t
representing the
result of the function fibonacci()
. Now, let’s look at the function
fibonacci()
:
std::uint64_t fibonacci(std::uint64_t n)
{
if (n < 2)
return n;
// We restrict ourselves to execute the Fibonacci function locally.
hpx::naming::id_type const locality_id = hpx::find_here();
// Invoking the Fibonacci algorithm twice is inefficient.
// However, we intentionally demonstrate it this way to create some
// heavy workload.
fibonacci_action fib;
hpx::future<std::uint64_t> n1 =
hpx::async(fib, locality_id, n - 1);
hpx::future<std::uint64_t> n2 =
hpx::async(fib, locality_id, n - 2);
return n1.get() + n2.get(); // wait for the Futures to return their values
}
This block of code is much more straightforward and should look familiar from
the previous example. First, if (n < 2)
,
meaning n is 0 or 1, then we return 0 or 1 (recall the first element of the
Fibonacci sequence is 0 and the second is 1). If n is larger than 1 we spawn two
tasks using hpx::async
. Each of these futures represents an
asynchronous, recursive call to fibonacci
. As previously we wait for both
futures to finish computing, get the results, add them together, and return that
value as our result. The recursive call tree will continue until n is equal to 0
or 1, at which point the value can be returned because it is implicitly known.
When this termination condition is reached, the futures can then be added up,
producing the n-th value of the Fibonacci sequence.
