I'm building a home energy controller, using CT's and arduino MEGA. I need to control 3 extra CT inputs and not sure how to use the 74HC4051 (multiplexer) with the EmonLib library. The problem I have is how to assign the same analog port to read the 3 extra CT inputs (voltage and current or just plain current). I tried, but I have no good results.
Does any one have a solution on how to do it?
Re: Adding extra analog inputs
Not knowing what you are doing with the multiplexer makes it hard to answer, but if my guess is correct, what you are looking for is 3 instances of EnergyMonitor that use the same physical I/O pin?
If so, all you must do is initialise each instance with the channel or pin, then before you call calcVI(...), you must switch as necessary with the multiplexer. It's probably more obvious for you to use EnergyMonitor::current(...) and EnergyMonitor::voltage(...) rather than EnergyMonitor::currentTX(...) and EnergyMonitor::voltageTX(...).
Re: Adding extra analog inputs
Which Arduino Mega are you using? Most of them have 16 analog input pins courtesy of the wider internal MUX in the bigger AVR processors (1280, 2560 etc.).
Re: Adding extra analog inputs
Mega 2560, 16 analog pins. Need extra 3 analog pins.
Re: Adding extra analog inputs
I'm trying to get 3 extra analog readings for 3 CTs to either read current or voltage. The other analog pins of the arduino MEGA 2560 are used to read other CTs.
I was thinking on initialize the instance, but I do not know how. How would you do it? I know how to switch the miltiplexer, but I do not know how to isolate the answers.
I do not know what you mean by "It's probably more obvious for you to use EnergyMonitor::current(...) and EnergyMonitor::voltage(...) rather than EnergyMonitor::currentTX(...) and EnergyMonitor::voltageTX(...)." Could you please explain?
I was using the code "Arduino sketch - voltage and current" modified to select the proper channel in the multiplexer.
This is my code:
#include "EmonLib.h" // Include Emon Library
EnergyMonitor emon1; // Create an instance
EnergyMonitor emon2;
double A;
void setup()
{
Serial.begin(9600);
emon1.voltage(0, 217.06, 0.7); // Voltage: input pin, calibration, phase_shift
emon2.current(0, 6.06); // Current: input pin, calibration.
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
pinMode(7,OUTPUT);
}
void loop()
{
digitalWrite(5, LOW);
digitalWrite(6, LOW);
digitalWrite(7, LOW);
emon1.calcVI(20,2000);
Serial.println(emon1.Vrms);
delay (1000);
digitalWrite(5, LOW);
digitalWrite(6, LOW);
digitalWrite(7, HIGH);
A= emon2.calcIrms(1480);
Serial.println(A);
Serial.println();
delay(1000);
}
Re: Adding extra analog inputs
Your sketch is missing some statements. I think you need to look carefully at the emonlib source code to see how each instance of the class is initialised and how those values make it into the methods that run inside loop( ) to read the power. You need to set up voltage and current for each instance of EnergyMonitor, even though all will use the same voltage input pin of the Arduino, and for the multiplexer those channels will also use the same current input pin of the Arduino.
You are reading real power with calcVI(...), so for each CT you must at the same time read a current and the voltage. It makes sense to have the voltage input on one of the Arduino inputs, and currents on 14 of the remaining Arduino inputs, with 4 extra currents on the 16th Arduino input via your multiplexer.
Therefore, you need to create 18 class instances:
EnergyMonitor emon1, emon2, emon3,....emon18;
emon1.voltage(0, 217, 0.7);
emon2.voltage(0, 217, 0.7);
emon3.voltage(0, 217, 0.7);
...
emon18.voltage(0, 217, 0.7);
because all instances us the same voltage input - pin 0, then
emon1.current(1, 6.06); - for the current on pin 1
emon2.current(2, 6.06); - for the current on pin 2
emon3.current(3, 6.06); - for the current on pin 3
...
emon14.current(14, 6.06); - for the current on pin 14
and for the multiplexed currents all going in on pin 15
emon15.current(15, 6.06); - for the current on pin 15 mpx 1
emon16.current(15, 6.06); - for the current on pin 15 mpx 2
emon17.current(15, 6.06); - for the current on pin 15 mpx 3
emon18.current(15, 6.06); - for the current on pin 15 mpx 4
and inside loop( ):
emon1.calcVI(20,2000);
emon2.calcVI(20,2000);
emon3.calcVI(20,2000);
...
emon15.calcVI(20,2000);
set multiplexer for sub-channel 1
emon15.calcVI(20,2000);
set multiplexer for sub-channel 2
emon16.calcVI(20,2000);
set multiplexer for sub-channel 3
emon17.calcVI(20,2000);
set multiplexer for sub-channel 4
emon18.calcVI(20,2000);
And the results for CT1 are in emon1.realPower / emon1.apparentPower etc,
for CT2 they are in emon2....
for CT3 they are in emon3....
...
and for the CT on channel 4 of your multiplexer, they are in emon18.... etc.
[All this isn't real code - it is only giving you the basic outline of how to do it.]
Re: Adding extra analog inputs
I have only put the code for the extra CTs I need to read by the multiplexer, which I wrote to test the code. All of the other instances are working fine in the main program I wrote.
In my test program I can read clearly voltage and when I load the CT for current reading the values I get do not correspond to anything.
I may try to see using voltage in one arduino pins and use current for the mux pins. Do not clearly understand your method.
Re: Adding extra analog inputs
Have you confirmed with a scope, or even a multimeter, that the signal at the Arduino pin is as expected after you've selected a CT input with the mux.... presumably it should be identical to the signal on the other side of the mux.
Re: Adding extra analog inputs
Joseglez,
What you have here:
EnergyMonitor emon1; // Create an instance
EnergyMonitor emon2;
emon1.voltage(0, 217.06, 0.7); // Voltage: input pin, calibration, phase_shift
emon2.current(0, 6.06); // Current: input pin, calibration.
is two separate instances of EnergyMonitor.
emon1 is set up with the voltage pin and the constants for the voltage but you have not set the current pin nor the current constant, and
emon2 is set up with the constants for the current pin and the current constant, but you have not set the voltage pin and the constants for the voltage.
The voltage for emon1 should be correct but the current and power should be zero (or very small) and the current for emon2 should be correct but likewise the voltage and power will be wrong. Each instance needs to read the voltage and the current in order to compute power.
For your multiplexer, you have 4 current channels - is that correct? If yes, then those 4 channels appear on the same Arduino input pin, therefore the 4 corresponding instances of EnergyMonitor must all use the same current input pin. The EnergyMonitor class has no knowledge of your multiplexer - as far as it is concerned, the multiplexer does not exist. But by having separate instances, and running calcVI after you set the multiplexer channel, you are selecting the output that the readings go to.
Re: Adding extra analog inputs
Sorry. I do not follow you at all.
How can I check the voltage reading? I believe I only can do it with calcVI. Right?
To check the amps I can use calcIrms independently the calcVI did it. Right?
In relation to your statement "emon1 is set up with the voltage pin and the constants for the voltage but you have not set the current pin nor the current constant" I only need to get the voltage.
In relation to your next statement, I only need to get the amps, not the power, so I do not need the voltage.. I also have to use de same pin as voltage, and that is the whole problem. Very difficult to understand, al least for me.
I have done only the mux for all current readings and got no good answers. I guess the EmonLib library does not like to use the same pin number to get results.
Re: Adding extra analog inputs
Now I am beginning to understand what you are doing. Most people want to know real power, because that relates directly to the energy they pay for. You have chosen to not do that, which is what confused me.
"How can I check the voltage reading? I believe I only can do it with calcVI?"
Correct - unless you write your own method to calculate it. That would be very easy to do because you would take calcVI( ) and remove the current reading and power calculations.
"To check the amps I can use calcIrms independently the calcVI did it. Right?"
It is not necessary that you use calcVI( ) to calculate current, but when you do, you will get a more accurate reading - because the voltage is available which means you can count cycles, which you cannot do with calcIrms( ). And you can know the values that calcVI calculated, they are all available:
emon1.realPower, emon1.apparentPower, emon1.Irms, emon1.Vrms and emon1.powerFactor.
But to use calcVI( ), you must have a voltage signal available to the Arduino at the same time as the current signal is available. That is why I put the voltage input on pin 0 (not through the multiplexer) and the current inputs on the other input pins.
Why do you want to measure current and voltage separately? Is real power not more important to you?
"I guess the EmonLib library does not like to use the same pin number to get results."
While you are using different instances of EnergyMonitor, each instance should be completely separate. For the emonTx, we normally use 4 instances and all 4 share the same voltage pin. So I think that is not the problem.
I suggest the multiplexer might not have settled before you start measuring, can you add a delay between switching the channel and starting the reading? You might also get better results if you use the "op.amp bias" circuit http://openenergymonitor.org/emon/node/673 using the same op.amp to provide the bias for all 18 inputs, which will ensure that all the inputs 'sit' at the same d.c. voltage.
Re: Adding extra analog inputs
As I said, I'm building a House Energy Controller. My house in Spain is all electric. I have a 3-phase supply 380-50Hz (4 wire) and the electric company will install a digital meter in no later than 10 months. This will put limit on the contacted power. I won't like to use more than the contact so I will lke to control which loads go in or out especially at night and during the winter (when heating is on). My normal use is 10kW daily in summer and 70-80kW in winter. I have a contract with time discrimination rates.
Electricity costs have gone up skyrocket in last few years and I will like to stay in this 60-80kW range contract.
The Open Energy Project sounded great for this. Do not need a very accurate reading of my power, just I want to stay within my contract.
My electronic knowledge is limited, although I have done several projects, asking when in doubt.
This "op.amp bias" circuit is a very good solution. In relation with testing the voltage is because I have noticed a not too steady supply at times (lived in an area country like). I'll do the testing randomly.
Not sure how the emonTX works, but with the mux I haven't been lucky (so far).
I'll keep on trying to see how I can use the mux, although I may have to schedule the use of the existing pins for different CT measurements. Because I have not being successful on reading using the same pin number.
Re: Adding extra analog inputs
Thank you for the explanation. It is now much clearer.
Firstly, you cannot accurately measure power by reading current alone. Secondly, because you have a 3-phase supply, you cannot assume the three voltages of the three phases will be the same. However, you understand those limitations, and though you will only calculate apparent power, you should have a good (probably within 10%) estimate of the real power.
I think you need to learn how the emonTx and emonLib works. The quick guide is:
CalcVI( ): The emonTx takes pairs of samples voltage and current 50 times (approximately) per cycle. Voltage and current are multiplied together, the total is added up. At the same time, the voltage is squared, the total added up. The same thing happens to the current. At the end of the 10 cycles, the average values are calculated and the average of V × I is real power. The average V2 is calculated, and the square root of that is the rms voltage, similarly the current.
CalcIrms( ): The emonTx takes readings of current, at about 5000 samples per second (twice the speed of calcVI because it is not reading the voltage). It cannot know when a mains cycle starts, so all you can do is guess how many samples it will read in (say) 10 cycles, and tell it to read that many samples. Each sample is squared, the total is averaged and the square root is Irms.
Your "emon1" is an instance of the class EnergyMonitor. All those measurements and calculations happen quite separately for each class instance, even though they might use the same voltage pin.
Part of reading the voltage (or current) is to select the input pin, and that is done with a multiplexer inside the processor component. Trystan Lea has used an external multiplexer here
http://openenergymonitor.org/emon/buildingblocks/rtd-temperature-sensing, and you can download the code and see how he did it. There is no fundamental reason why the multiplexer does not work.
One thing I do notice: Trystan put a 10 ms delay (delay(10);) between setting the multiplexer and reading the analogue value. You might need to do the same. If you start reading before the multiplexer has finished switching, you might get a large voltage step at the analogue input pin because the voltage and current inputs sit at slightly different d.c. voltages. If you read the edge of that step, you will certainly get wrong readings. The op.amp bias supply should remove that step, but it would still be a good idea to have a small delay.
[You might like to look at this http://openenergymonitor.org/emon/node/11143 - calcIrms(1228) seems to be a good value to choose. If you are reading a random part-cycle of current at the end, your Irms readings will vary because the maths assumes an exact number of whole cycles.]
Re: Adding extra analog inputs
I finally made it to work. The problem was a faulty mux. I started fresh, replaced all the components one by one and once I replaced the mux everything worked as it should. Now, I can continue with the project.
I appreciate the help I received and for sure now I have a more intense knowledge of the system. I hope I will have the same attention in case I need it. Thanks again.

MSG_LOCATOR_DO_CHAR_LOCATE
The Locator object can be in one of two modes: index mode or text search mode. The Locator object will appear and act differently depending on it operating mode.
When the Locator object is in index mode, it takes the form of an action bar, shown below:
Tapping on one of the Locator's dyad buttons (`AB', `EF', etc.) sends
MSG_LOCATOR_DO_CHAR_LOCATE
to the Locator object itself. The Locator responds to this request by sending
MSG_TABLE_CHAR_LOCATE
to its linked Table. Intercept that message in
TableClass
to provide your searching behavior.
Repeatedly clicking on a dyad button will cycle through the two letters of the dyad to perform the search. For example, clicking once on the `AB' dyad button will send the aforementioned messages with a character argument of `A.' Clicking again on that button will send these messages with an argument of `B' and clicking yet again on that button will send these messages with an argument of `A' again.
You will probably not want to implement any searching behavior in your Locator object; it is sufficient merely to include the Locator object and intercept
MSG_TABLE_CHAR_LOCATE
in the Table object itself. This is discussed in Handling Locator Searches
.
Boolean MSG_LOCATOR_DO_CHAR_LOCATE( char searchChar);
This message instructs a Locator object (in index mode) to locate the entered character within the
TableClass
object that is in the Locator's LI_
destination
field. It does this by sending the Table object
MSG_TABLE_CHAR_LOCATE
, passing it the search character. You will want to intercept that message within your subclass of
TableClass
to implement your search criteria.
When in index mode, this message is sent with a single index letter (e.g. `A', or `B' in the "AB" dyad) of the tapped dyad button. Repeatedly tapping on a dyad button will cycle through the indexed letters, sending out this message a separate time for each tap (first with `A,' then with `B,' and then with `A' again). For this reason, make sure that code that implements this message is not run under the UI thread. (Doing so may result in bothersome screen "glitches" as the Table scrolls first to the `A' entries, then to the `B' entries, etc.
Source: The Locator object.
Destination: A Locator object.
Parameters:
searchChar
Character to pass to
MSG_TABLE_CHAR_LOCATE
.
Return: Non-zero if the search failed. Note that if you do not write a search method for TableClass, this message will always return non-zero.


Press release
Schools should be doing more to prepare young people for the world of work
The nation's economic prosperity is at risk because the majority of England’s schools fail to prioritise enterprise education and work-related learning.
The survey,
‘Getting ready for work’
finds that only 4 of the 40 secondary schools visited by inspectors were demonstrating an effective approach to this aspect of the curriculum, despite the government’s commitment to take forward the recommendations made in Lord Young’s 2014 report into these matters.
The survey also finds that poor coordination between schools and businesses and the absence of any overarching government strategy are leaving large numbers of young people – particularly the disadvantaged – unprepared for the world of work.
Enterprise education involves teaching pupils the knowledge they will need to be future employees and potential employers by providing opportunities to raise their awareness of problems and solutions in the context of business and enterprise. It also involves teaching young people to make informed choices about their finances.
Commenting on the report findings, HM Chief Inspector, Sir Michael Wilshaw, said:
The question of how well our school system is preparing young people for the world of work has never been more important. The future success and prosperity of the UK in a post-Brexit world will increasingly depend on our ability to harness home-grown talent and to encourage the creativity and innovation of our young people. That will mean making sure that pupils from all backgrounds have access to an education that prepares them well for the next stage of their lives, be that higher education, entering employment or setting up their own business.
The career choices that young people make can be informed by the practical experience they gain at school. It is really important that schools are providing the right opportunities, working effectively with local businesses to offer their pupils the chance to understand how businesses work. This is even more important for young people from disadvantaged backgrounds.
One of the ways we can bridge the social divide is by ensuring all young people have equal access to work-related knowledge that will guide and prepare them for the next stage of their lives.
Key findings from the report include:
-
the extent to which schools used their curriculum to prepare pupils for the world of work was largely dependent on whether school leaders considered it to be a priority. Schools often cited pressures on finance and curriculum time as reasons for not prioritising enterprise education. In the schools where there was limited focus on enterprise learning, school leaders told inspectors that they see themselves as accountable for outcomes narrowly focused on examinations. This was particularly acute in the schools visited that had most recently been judged as requires improvement or inadequate.
-
even where schools were delivering enterprise education, it was often unclear whether this was having any impact on pupils’ knowledge, understanding and skills. Pupils who spoke to inspectors during the visits frequently said that their experience tended to be a series of one-off events that lacked any sense of progression. In 32 of the 40 schools visited, there was no monitoring to check whether opportunities to gain enterprise knowledge or employability skills were taken up by different groups of pupils.
-
opportunities for pupils to take part in meaningful work-related learning or work experience were limited at key stage 4. Some schools offered work experience to a small group of pupils, often selected on the basis of not achieving well in academic subjects. Where this was the case, school leaders frequently suggested that arranging work experience for all pupils was too time-consuming and impractical to administer on a large scale.
-
business involvement in some of the schools visited relied too heavily on the personal networks of teachers and parents. Some arose solely because the pupils’ parents were well connected, potentially resulting in disadvantaged pupils missing out.
-
a lack of coordination across local areas has created an environment for schools and businesses that business leaders described as ‘chaotic’. Business leaders consulted for this report raised concerns that there is little coherence to provision and a lack of strategy by government, business organisations or individual schools.
-
schools appear to be more likely to promote apprenticeships than in recent years, but parents and pupils are concerned about the quality and reputation of apprenticeships. Some parents and pupils were concerned about the current state of the apprenticeship market and were reluctant to pursue a route that they thought would narrow their options in the future.

Keep a CHANGELOG
Don’t let your friends dump git logs into CHANGELOGs™
What's a CHANGELOG?
A CHANGELOG is a file which contains a curated chronologically ordered list of notable changes for each version of an open source project.
What's the point of a CHANGELOG?
To make it easier for users and contributors to see precisely what notable changes have been made between each release (or version) of the project.
Why should I care?
Well, because software tools are for people. If you don't care, why are you contributing to open source? There must be a kernel (ha) of care somewhere in that lovely little brain of yours.
I talked with Adam Stacoviak and Jerod Santo on The Changelog (fitting, right?) podcast about why open source maintainers and contributors should care, and the motivations behind this project. If you can spare the time (1:06), it's a good listen.
What makes up a good CHANGELOG?
I'm glad you asked.
- It's made for humans, not machines, so legibility is crucial.
- One sub-section per versions.
- Versions should come with a release date in a sensible format: YYYY-MM-DD.
- Changes should be grouped to describe their impact on the project:
Added
for new features.Deprecated
for once stable features removed in upcoming releases.Removed
for deprecated features removed in this release.Fixed
for any bug fixes.Security
to invite users to upgrade in case of vulnerabilities.
- Each section should be easily linked to — hence Markdown over plain text.
- Write release dates in an international, sensible, and
language-independent format:
2012-06-02
forJune 2nd, 2012
. - Order the releases reverse chronologically (latest at the top).
It's also good to mention whether the project follows Semantic Versioning.
What makes unicorns cry?
Alright, let's get into it:
- Dumping a diff of commit logs. Just don't do that, you're helping nobody.
- Not emphasizing deprecations: when people upgrade from one version to another it should be painfully clear when something will break.
- Dates in regionally-specific formats. Americans put the month first ("06-02-2012" for June 2nd, 2012, which makes no sense), while Brits use a robotic-looking "June 2 2012", yet pronounce it "June 2nd, 2012".
There's more. Help me collect those unicorn tears by opening an issue or a pull request.
Is there a standard CHANGELOG format?
Sadly, no, but this is something I want to change. This project contains what I hope will become the standard CHANGELOG file for all open source projects, so take a look at it and please suggest improvements.
What should the CHANGELOG file be named?
Well, if you can't tell from the example above, CHANGELOG.md
is the
best convention so far.
Some projects also use HISTORY.txt
, HISTORY.md
, History.md
, NEWS.txt
,
NEWS.md
, News.txt
, RELEASES.txt
, RELEASE.md
, releases.md
, etc.
It's a mess, that only makes it harder for people to find it.
Why can't people just use a git log diff?
 Can we really expect every single commit in an open source project to be meaningful and self-explanatory? That seems like a pipe dream.
Can CHANGELOG files be automatically parsed?
It's hard because people follow wildly different formats and file names. Vandamme is a Ruby gem created by the Gemnasium team and which parses many (but not all) open source project CHANGELOGs.
Why do you keep writing CHANGELOG in all caps?
You're right, that is a bit shouty. Maybe it's because of the de facto
convention that files pertaining to an open source project should be in
all caps, for instance: README
, LICENSE
,
CONTRIBUTING
.
It denotes that these files are metadata for the project, similarly to open source project badges they draw attention to themselves as information people should be aware of if they mean to use the project or contribute to it.
How can I contribute?
This document is not the truth, it's my carefully considered opinion with the information and examples I was able to gather. Although I provide an actual CHANGELOG on the GitHub repo, I have purposefully not created a proper release or clear list of rules to follow like SemVer.org does for instance. This is because I want our community to reach a consensus. I believe the discussion is as important as the end result. So please pitch in.


Wiki ▸ [[Geometry]] ▸ Quadtree Geom
A quadtree is a two-dimensional recursive spatial subdivision. This implementation uses square partitions, dividing each square into four equally-sized squares. Each point exists in a unique node; if multiple points are in the same position, some points may be stored on internal nodes rather than leaf nodes. Quadtrees can be used to accelerate various spatial operations, such as the Barnes-Hut approximation for computing n-body forces, or collision detection.
# d3.geom.quadtree()
Creates a new quadtree factory with the default x-accessor, y-accessor and extent. The returned function can be used to create any number of quadtrees from data with the factory’s configuration.
# quadtree(points)
Constructs a new quadtree for the specified array of data points, returning the root node of a new quadtree. The x- and y-coordinates of each point are determined using the current x- and y- accessor functions. To build a quadtree by adding points incrementally, the specified points array can be empty, and then points can be later added to the returned root node; in this case, you must also specify the extent of the quadtree.
Each node in the quadtree has several properties:
The returned root node also defines add and visit methods.
# root.add(point)
Adds the specified new point to the quadtree.
# root.visit(callback)
Visits each node in the quadtree, invoking the specified callback with arguments {node, x1, y1, x2, y2} for each node. Nodes are traversed in pre-order. If the callback returns true for a given node, then the children of that node are not visited; otherwise, all child nodes are visited.
# root.find(point)
Given any point [x,y], returns the closest point in the quadtree.
# quadtree.x([x])
If x is specified, sets the x-coordinate accessor and returns this quadtree factory. If x is not specified, returns the current x-coordinate accessor, which defaults to:
js
function(d) { return d[0]; }
For each point added to the quadtree, either during initial construction or lazily added, the x-accessor is invoked with the arguments {d, i}, where d is the current point and i is its index in the array of all points. The x-accessor must then return a numeric value indicating the x-coordinate of the given point. The x-accessor may also be defined as a constant number rather than a function, if desired.
# quadtree.y([y])
If y is specified, sets the y-coordinate accessor and returns this quadtree factory. If y is not specified, returns the current y-coordinate accessor, which defaults to:
js
function(d) { return d[1]; }
For each point added to the quadtree, either during initial construction or lazily added, the y-accessor is invoked with the arguments {d, i}, where d is the current point and i is its index in the array of all points. The y-accessor must then return a numeric value indicating the y-coordinate of the given point. The y-accessor may also be defined as a constant number rather than a function, if desired.
# quadtree.extent([extent])
If extent is specified, sets the current extent and returns this quadtree factory. If extent is not specified, returns the current extent, which defaults to null. When the extent is null, an extent will be computed automatically by scanning the array of input points passed to the quadtree constructor. Otherwise, the extent must be specified as a two-dimensional array [[x0, y0], [x1, y1]], where x0 and y0 are the lower bounds of the extent, and x1 and y1 are the upper bounds of the extent. Setting an extent is required when constructing a quadtree lazily from an initially-empty set of nodes.

Fire Emblem: Three Houses adds sauna and maid costumes
Follow Polygon online:
by Patricia HernandezYou know what would go really well with a long, grueling story about war and trauma? New outfits and ways to blow off steam, clearly.
The latest wave of DLC for Fire Emblem: Three Houses has hit today, and the patch brings with it a bevy of new content. There are new threads for all students, including the obligatory maid and butler costumes that will make cutscenes hilarious. (Maids and butlers are now a type of recruitable battalion, too.) There’s now a sauna mechanic as well, which allows you to soak in the heat with your classmates.
And, fan favorite Anna the Merchant is back as a recruitable character now, along with the moody Jeritza (but only on the Black Eagles route.) Anna doesn’t have any support conversations, unfortunately, but she does come with a paralogue story mission.
Perhaps the most important addition in wave 3 is the ability to spend time with the many animals roaming around the monastery. You can now interact with the dogs and cats by giving them gifts. Yay!
You can read the full patch notes here.

--- title: Goal Operations for Cognitive Systems layout: post description: "AAAI-17 Paper" tags: [paper] comments: true category: Conference Paper ---
Abstract: Cognitive agents operating in complex and dynamic domains benefit from significant goal management. Operations on goals include formulation, selection, change, monitoring and delegation in addition to goal achievement. Here we model these operations as transformations on goals. An agent may observe events that affect the agent’s ability to achieve its goals. Hence goal transformations allow unachievable goals to be converted into similar achievable goals. This paper examines an implementation of goal change within a cognitive architecture. We introduce goal transformation at the metacognitive level as well as goal transformation in an automated planner and discuss the costs and benefits of each approach. We evaluate goal change in the MIDCA architecture using a resource-restricted planning domain, demonstrating a performance benefit due to goal operations.

Module timer
Copas Timer is a module that adds a timer capability to the Copas scheduler.
It provides the same base functions copas.step and copas.loop
as Copas (it actually replaces them) except that it will also check for (and
run) timer expiring and run background worker if there is no IO or timer to
handle.
To use the module it should be required as; local copas =
require("copas.timer")
because it returns the global copas
table and not a separate timer table.
There is a difference between the 2 background mechanisms provided; the
timer runs on the main loop, and hence should never yield. A worker runs in
its own thread (coroutine) and can be yielded (worker:pause ) if they take too long.
The workers are dispatched from a rotating queue, so when a worker is up to run
it will be removed from the queue, resumed, and (if its queue isn't empty) added at the end
of the queue again.
Info:

Class queueitem
Object created by
worker:push when data is pushed into the
worker queue. This
object can be tracked for progress or cancellation.
-
queueitem.cancelled
-
flag;
true
when the element has been cancelled.
-
queueitem.completed
-
flag;
true
when the element has been completed or cancelled.
'completed' is when the worker is finished with it and requests the next element by calling its worker:pop function
-
queueitem.data
-
The actual data contained within the queueitem .
-
queueitem.worker
-
The worker object for which this queueitem has been enqueued.
-
queueitem:cancel ()
-
Cancels the queueitem .
When cancelling both the cancelled and completed
flag will be set. The cancelled flag will prevent the data from being executed
when it is being popped from the queue.
-
queueitem:complete ()
-
Marks the queueitem as completed.
The completed flag will be set. Generally there is no need to call this method, it will
be called when the worker handling this element pops the next element from its queue.
Worker functions
-
copas.addworker ([obj], func[, errhandler])
-
Creates a worker and adds it to the Copas scheduler. The workers will be executed when there is no I/O nor
any expiring timer to run. The function will be started immediately upon
creating the coroutine for the worker. Calling worker:push on
the returned worker table will enqueue data to be handled. The function can
fetch data from the queue through worker:pop which will
pop a new element from the workers queue. For lengthy operations where the code needs
to yield without popping a new element from the queue, call worker:pause .
Parameters:
- obj
object the worker relates to
- func
function
function to execute as the coroutine. It takes as arguments
obj
and worker , where obj
is only provided when it is passed to addworker . It allows to use obj
as self
in the worker function. See both examples below.
- errhandler
function
function to handle any errors returned or
nil
(should be a function taking 2 arguments; 1 - coroutine generating the error, 2 - returned error)
Returns:
worker
See also:
Usage:
local obj = {}
function obj:display(data) print(data) end
function obj:handler(worker) while true do
data = worker:pop() self:display(data) end
end
obj.worker = copas.addworker(obj, obj.handler)
obj.worker:push("here is some data")
local w = copas.addworker(function(queue)
while true do
data = queue:pop() print(data)
queue:pause() end
end)
w:push("here is some data")
-
copas.getworker (t)
-
Returns a background worker .
Parameters:
Returns:
the worker table (as earlier returned by copas.addworker )
Or
nil
if the coroutine wasn't found
See also:
Usage:
if copas.getworker(coroutine.running()) then
print ("I'm running as a background worker")
else
print ("No background worker found, so I'm on my own")
end
-
copas.removeworker (t)
-
Removes a worker from the Copas scheduler.
Parameters:
- t
coroutine or worker object to be removed
Returns:
worker
Or
nil
if the coroutine/worker wasn't found
Class worker
This class represents a
worker and its queue with
queueitem objects. It can be used to manipulate the worker and push data to it.
-
worker.errhandler
-
Holds the errorhandler for this worker
-
worker.paused
-
Flag indicating that the worker has been paused by a call to worker:pause (with parameter
seconds

-
worker.queue
-
Holds the list of queueitem objects waiting to be processed by the worker
-
worker.thread
-
Holds the coroutine for this worker
-
worker.timer
-
Holds the timer that monitors the delay by worker:pause . If the timer is cancelled, the worker will be resumed.
-
worker:pause (seconds)
-
Yields control in case of lengthy operations. Similar to worker:pop except
that this method does not pop a new element from the worker queue.
Parameters:
- seconds
(optional) the number of seconds to pause, default = 0
Returns:
true
-
worker:pop ()
-
Retrieves data from the worker queue (and implicitly yields control). Note that this method
implicitly yields the coroutine until new data has been pushed in the worker queue.
Returns:
data field of the next queueitem popped from the queue
-
worker:push (data)
-
Adds data to the worker queue. If the worker has died, it will return an error
and nothing will be enqueued.
Parameters:
- data
Data (any type) to be added to the queue of the worker
Returns:
queueitem that was added to the worker queue
Or
-
nil
-
error message
Usage:
local w = copas.addworker(myfunc)
w:push("some data")
Timer functions
Creating and handling timers
-
copas.cancelall ()
-
Cancels all currently armed timer objects.
See also:
-
copas.newtimer (f_arm, f_expire, f_cancel, recurring, f_error)
-
Creates a new timer .
After creating call the arm method of the new timer to actually
schedule it. REMARK: the background worker run on their own coroutine
and hence need to yield control when their operation takes too long, but
the timer run on the main loop, and hence the callbacks should never
yield, in those cases consider adding a worker through
copas.addworker from the timer callback.
Parameters:
- f_arm
function
callback function to execute when the timer is armed, or
nil
- f_expire
function
callback function to execute when the timer expires
- f_cancel
function
callback function to execute when the timer is cancelled, or
nil
- recurring
boolean
(boolean) should the timer automatically be re-armed with
the same interval after it expired
- f_error
function
callback function to execute (in a xpcall call), or
nil
when any of the other callbacks generates an error
See also:
Usage:
local t = copas.newtimer(nil, function () print("hello world") end, nil, false, nil)
copas.newtimer(nil, function () print("hello world") end, nil, false, nil):arm(5)
local f = function () print("hello world") end
copas.newtimer(f, f, nil, true, nil):arm(5)
Class timer
-
timer:arm (interval)
-
Arms a previously created timer . When arm is called on an already
armed timer then the timer will be rescheduled, the cancel handler
will not be called in this case, but the arm handler will run.
Parameters:
- interval
number
the interval after which the timer expires (in seconds). This must
be set with the first call to arm any additional calls will reuse
the existing interval if no new interval is provided.
Returns:
timer
See also:
Usage:
local f = function() print("hello world") end
local t = copas.newtimer(nil, f, nil, false)
t:arm(5) local t = copas.newtimer(nil, f, nil, false):arm(5)
-
timer:cancel ()
-
Cancels a previously armed timer. This will run the cancel handler
provided when creating the timer .
See also:
Usage:
local t = copas.newtimer(nil, function () print("hello world") end, nil, false)
t:arm(5) t:cancel() -- cancel it again
Copas core
Adapted base functions and some additional ones.
-
copas.exitloop (timeout, keeptimers)
-
Instructs Copas to exit the loop. It will wait for any background worker to complete their queue.
If the
copas.eventer
is used then the timeout will only start after the
copas.events.loopstopping
event has been completely handled.
Parameters:
- timeout
number
Timeout (in seconds) after which to forcefully exit the loop,
abandoning any worker still running.
nil
: no timeout, continue running until all workers have emptied their queues
< 0
: exit immediately after next loop iteration, do not
wait for workers nor the copas.events.loopstopping/loopstopped
events to complete
(timers will still be cancelled if set to do so)
- keeptimers
boolean
if
true
then the active timers will NOT be cancelled, otherwise
copas.cancelall will be called to properly cancel all running timers.
See also:
-
copas.isexiting ()
-
Indicator of the loop running or exiting.
Returns:
nil
when the loop is not running
Or
false
when the loop is running
Or
true
when the loop is scheduled to stop
See also:
Usage:
if copas.isexiting() ~= nil then
copas.exitloop(nil, false)
end
-
copas.loop (timeout, precision)
-
Executes an endless loop handling Copas steps and timers (it replaces the original copas.loop ).
The loop can be terminated by calling copas.exitloop .
Parameters:
- timeout
number
time out (in seconds) to be used. The timer list
will be checked at least every
timeout
period for expired timers. The
actual interval will be between 0
and timeout
based on the next
timers expire time or worker threads being available. If not provided, it defaults to 5 seconds.
- precision
number
the precision of the timer (in seconds). Whenever the timer
list is checked for expired timers, a timer is considered expired when the exact
expire time is in the past, or up to
precision
seconds in the future.
It defaults to 0.02
if not provided.
See also:
-
copas.step (timeout, precision)
-
Executes a single Copas step followed by the execution of the first expired
(if any) timer in the timers list (it replaces the original copas.step )
if there is no timer that expires then it will try to execute a worker if available.
Parameters:
- timeout
number
timeout value (in seconds) to pass to the original Copas step handler
- precision
number
see parameter
precision
at function copas.loop
Returns:
time in seconds until the next timer in the list expires
Or
0 if there are worker objects with non-empty queues
Or
nil
if there is no timer nor any worker with work to do
See also:
Utility functions
Some useful functions using timers, for timed actions and checks.
-
copas.delayedexecutioner (delay, func, ...)
-
Calls a function delayed, after the specified amount of time.
An example use is a call that requires communications to be running already,
but if you start the Copas loop, it basically blocks; classic chicken-egg. In this case use the
delayedexecutioner to call the method in 0.5 seconds, just before
starting the CopasTimer loop. Now when the method actually executes, communications
will be online already. The internals use a timer , so it is executed on the main
loop and should not be suspended by calling
yield()
.
Parameters:
- delay
number
delay in seconds before calling the function
- func
function
function to call
- ...
any arguments to be passed to the function
Returns:
timer implementing the delay
See also:
Usage:
local t = socket.gettime()
copas.delayedexecutioner(5, function(txt)
print(txt .. " and it was " .. socket.gettime() - t .. " to be precise.")
end, "This should display in 5 seconds from now.")
-
copas.waitforcondition (interval, timeout, condition, handler, ...)
-
Executes a handler function after a specific condition has been met
(non-blocking wait). This is implemented using a timer , hence both the
condition
and handler
functions run on the main
thread and should never yield.
Parameters:
- interval
number
interval (in seconds) for checking the condition
- timeout
number
timeout value (in seconds) after which the operation fails
(note that the
handler()
will still be called)
- condition
function
a function that is called repeatedly. It will get the
additional parameters specified to waitforcondition . The
function should return
true
or false
depending on
whether the condition was met.
- handler
function
the handler function that will be executed. It will
always be executed. The first argument to the handler will
be
true
if the condition was met, or false
if the
operation timed-out, any additional parameters provided to
waitforcondition will be passed after that.
- ...
additional parameters passed on to both the
condition
and handler
functions.
Returns:
timer that verifies the condition.
Usage:
local count = 1
function check(param)
print("Check count ", count, ". Called using param = ", param)
count = count + 1
return (count == 10)
end
function done(conditionmet, param)
if conditionmet then
print("The condition was met when count reached ", count - 1,". Called using param = ", param)
else
print("Failed, condition was not met. Called using param = ", param)
end
end
copas.waitforcondition(0.1, 5, check, done, "1234567890")

SDX Energy begins gas production at Egyptian site
by Edward ThicknesseUK oil and gas exploratory firm SDX Energy announced this morning that production had started at the company’s South Disouq concession in Egypt.
Each of the site’s four discovery wells have been tested and gas has been flowing since the 7 November.
Read more: E.on and RWE Renewables agree clean power deal
All gas production at the site, in which SDX owns a 55 per cent stake, will be sold to Egypt’s national gas company Egas.
The company said that initial flow rates were in line with expectations and that SDX will gradually ramp up production with a view to achieving its targeted production rate of 50m standard feet per day in the first quarter of 2020.
The firm also announced that interim chief executive Mark Reid had taken up the role permanently, with Nick Box becoming chief financial officer.
Reid said: “The Company is pleased to announce the commencement of production at our South Disouq concession in Egypt.
“Production, which is coming on stream in line with our previous guidance, will result in a material increase to Company’s cash flow going forward. We look forward to providing the market with further updates in due course.”
SDX’s primary focus is the Middle East and North Africa, with three producing assets across Egypt.
Analysts at SP Angel welcomed the news, saying: “A plateau targeted gross production rate of 50MMscfe/d will provide the company with a material boost to operating cash flows ahead of a drilling campaign of up to five exploration wells in 2020 on the field.

“These wells will target the same Abu Madi and Kafr el Sheik prospective horizons that have seen the company make four discoveries from the five wells drilled to date.
“Mark Reid’s appointment to CEO is another positive in our view, bringing a wealth of financial and sector experience to this key position ahead of an active period for the company.”
Shares in SDX rose 3.6 per cent this morning.

Interface IGridView<T>
Interface designed to act as a standardized input/output format that defines minimal required data for algorithms that operate on a grid of some sort. For a concrete implementation to subclass for custom implementations, see GridViewBase<T>.
Namespace: SadRogue.Primitives.GridViews
Assembly: TheSadRogue.Primitives.dll
Syntax
public interface IGridView<out T>
Type Parameters
| Name | Description |
|---|---|
| T | The type of value being returned by the indexer functions. |
Remarks
Many algorithms that operate on a grid need only some very basic information about each location in the grid to function. For example, a basic grid-based pathfinding algorithm might only need to know whether each location can be traversed or not, which can be represented by a single boolean value per location. A renderer might want to know simple rendering information for each location, which might be wrapped in a class or structure.
One option for creating these algorithms would be to take as input arrays of the type they need. For example, the pathing algorithm might take an array of boolean values as input. However, this can be quite inflexible. The values that algorithms need to function might be determined based on a much more complex structure than a simple array of the precise type it needs, depending on use case. Taking an array as input in these cases forces a user to either adapt their data structure to the one that the algorithm uses, or maintain multiple "copies" of their data in the format that the algorithms need.
IGridView<T> is designed to act as a much more flexible input/output format for algorithms like this that operate on a grid. The interface simply defines properties for width and height, and some basic abstract indexers that allow accessing the "object" at each location. In the examples from above, the basic pathfinding algorithm might take as input an IGridView<bool>, whereas the renderer might take IGridView<RenderingInfo>. This allows the algorithms to operate on the minimal data that they need to function, but allows a user to define where that data comes from. For common cases, concrete implementations are provided that make the interface easier to use; for example, ArrayView<T> defines the interface such that the data comes from an array, and LambdaGridView<T> defines the interface such that an arbitrary callback is used to retrieve the data.

Dark theme is good.
Other Stuff
Are you still reading? I appreciate your dedication and interest. What's keeping you here? Why are you doing this? The page will soon run out of content for you to read.

You didn't stop.  You really want to read it huh?  Just so you know, you could be reading anything else, since you like reading this much. You read pretty well, congratulations.
STOP READING PLEASE, I have nothing else to say. I understand you like reading because you are a curious human being but this just can't go on. Nice things don't last long, you know? I know you know that, and I know that you know that I know that. What do you want now? Just think about what you are doing: you are reading text on a page, and somehow not getting bored, you are really a very interesting person. What's your name? Oh I forgot I cannot possibly hear you, but feel free to say your name out loud, I'll pretend that I heard it and say "Oh what a nice name you have." Isn't that how dialog goes? I'm not sure, I don't usually talk to people that much.
 I really like you but for a greater good, I must stop writing.  Hm, maybe that is what you want after all, you want to learn something from this? Ok this will be the last thing I'm gonna do. What do you want to learn? Oh I know something interesting. Climbing stairs consumes an average of 9 calories per minute. Do you find that interesting? I hope you do. Now go, forget that I exist. Good luck on your adventures, Mr Reader.

This Is An Ad, Within An Ad, Within An Ad, And It’s Absolutely Brilliant
by Geoff DesreumauxA gin brand, a TV, and a new movie: Ryan Reynolds advertises all of it with an ad, within an ad, within an ad. Finding it hard to follow? Just watch.
Ryan Reynold is not just a great actor; he is a successful businessman and one heck of an advertiser too. Do you remember his OOO email campaign for Aviation Gin? Well, he is back, and this time the situation is very meta.
In his new ad, Reynolds pitches a Samsung TV as the best TV to watch his upcoming Netflix movie ‘6 Underground’. This makes perfect sense and showcases a real case of smart brand collaboration.
But there’s a catch. Reynolds also bought ‘a mid-roll ad’ for his own Aviation Gin brand. The result? An ad, within an ad, within an ad. And it’s absolutely brilliant! All this, in under a minute!
‘6 Underground’ is directed by Michael Bay and hits Netflix on December 13th.
