Overview daScript is high-performance statically strong typed scripting language, designed to be data-oriented embeddable ‘scripting’ language for performance critical applications (like games or back-end/servers). daScript is:
daScript offers a wide range of features like:
daScript is inspired by languages like Python in terms of it's explictness and readability; while it is designed to be extremely fast.
def fibR(n) if (n < 2) return n else return fibR(n - 1) + fibR(n - 2) def fibI(n) var last = 0 var cur = 1 for i in range(0, n-1) let tmp = cur cur += last last = tmp return cur Development state
The project has been compiled and run on Windows(x86 & x64), Linux(x64), macOS, Xbox One, PlayStation 4, Nintendo Switch, iOS and Android. Has been tested with the following compilers with C++14 support:
The documentation has to be improved. In order to compile, it requires C++14 support. Performance As interpreted language it typically beats everything, including blazing fast LuaJIT. Especially it shines in interop with C++ functions, which allows easy and nice experience to integrate new functions and types. The total overhead over C++ of data oriented processing in interpretation is close to C++ in Debug mode (see Particles sample). As compiled Ahead-of-Time language it is also much faster then both LuaJIT and Chrome JS (both having extremely fast Just-in-Time). It is almost on par with naive C++ (clang-cl llvm 8.0.1 with all optimizations), usually within 10% of difference, and sometimes can even beat it! It is worth noting that unlike Just-in-Time, Ahead-of-Time compilation can be used on any platform, including those with signed binaries executables (such as iOS or consoles). All times are in milliseconds, all results are measured as best-out-of-20 runs on Intel Core i5. All samples for all languages in comparison are available in GitHub Work in Progress

When going through my learning objectives, I learned about a great library for game development in Javascript called "Phaser."
Phaser makes it easy to incorporate commonly used dynamics into your game, and through some experimenting and with treehouse's help, I was able to make a basic coin grabber. Here's a link to the phaser site. Check it out!
Not much to say here! Just a great logic exercise. I would like to return to this app for a bit of re-factoring, and to perhaps add some animations.
One common exercise in javascript I see going around a lot is the idea of dynamically adding new elements with custom content into the DOM. Although this is not like a comment system that would perhaps be handled server-side, this app is still pretty cool.
The idea for the app came from treehouse again, although it was built custom by me. It is a list generator that, well, generates a list!

SMILLA'S SENSE OF SNOW 1997 A film review by Timothy Voon Copyright 1998 Timothy Voon 1 :-) for the ice maiden
When I first heard that Smilla had a sense of snow, I was expecting her to climb Mt Everest. She doesn't. Instead this ice maiden spits liquid nitrogen with a vengeance and shoots icicles from her arse. She is one seriously, emotionally frozen lass who is perpetually on the edge of the toilet seat. What is Smilla's problem? Her Icelandic mother died when she was six depriving her of the comfort of breast milk. Her Anglo-Saxon father whisks her away to the confines of Denmark, away from the open spaces of Greenland. She then competes with her father's bimbette mistress for his love, before she befriends a deaf Icelandic boy who gets pushed off the roof of her apartment blocks. So it's not surprising that Smilla (Julia Ormond) gets pretty pissed off when her only friend gets killed. The reclusive, bitter Smilla shouts foul play, not because she has a feeling for snow, but because she's got a feeling it's murder.
The story then revolves around bizarre meteorites and ancient parasitic worms, which is all fantastically unbelievable. These elements serve as a mere distraction to the far more interesting Smilla on which the story is based. This woman who bites, fights, spits to get her way makes an interesting character, but she is also confused, frightened and fragile making her a bit of an enigma. If only this movie carried more romance than mere mystery and suspense, then perhaps Gabrielle Byrne would not have been wasted as a male body. He gets to bed Smilla and temporarily defrosts the ice maiden, but that's as interesting as his character gets. Annoyingly, he is so mysterious that he can't make up his mind whether he wants to be a good guy or bad guy – leaving the audience with little hope of figuring him out.
This movie has an interesting feel to it that one finds hard to put into words, except to say that one gets a good sense of frost when Smilla's around. Although it scores poorly in the department of plot conclusion, it redeems itself in creating a character as memorable as Smilla.

While this Perspective focuses on feedbacks that act through physical processes in polar regions (Table 1, Fig. 1), we should mention that many other feedback processes exist, some of which involve biological processes and biogeochemical cycles 65– 68. One example is the bio-optical feedback, which occurs when climate warming and sea ice retreat in the Arctic Ocean lead to intense phytoplankton blooms 69. These blooms trap the penetrating solar heat flux at the ocean surface, which increases sea surface temperature. As a result, sea ice concentration decreases, which leads to enhanced absorption of solar energy into the ocean and further warming of the Arctic 70.
The response to a perturbation also implies a redistribution of the energy between different latitudes. First, the warming of the tropics under greenhouse gas forcing leads to enhanced poleward energy transport by the atmospheric circulation to higher latitudes, contributing to warming there 71– 75. This indicates a coupling between radiative feedbacks and atmospheric heat transport 74, 76, 77. Moreover, radiative feedbacks at low latitudes may influence polar warming through their effect on poleward energy transport, while changes in polar regions may affect dynamics in the lower latitudes 78. This is an area of ongoing research, and it is not yet clear if the response of the system has a direct impact on the original perturbation itself such that a closed feedback loop can be identified.
Second, the ocean heat transport has been found to strongly shape polar climate change, with increased poleward heat transport into the Arctic 79– 81 and decreased poleward heat transport into the Southern Ocean 4, 79 under global warming. Here too, it is unclear whether these changes can be represented in terms of a closed feedback loop (e.g., sea ice thinning enhancing ocean heat transport into the Arctic 81) or should be classified as important drivers of polar climate change that cannot be expressed within a feedback framework.


Running opengl under WSL
Opengl and WSL
There is little information about opengl under wsl. The first post that comes up on google with a blog states that opengl doesn’t function under WSL and he gave up.
https://bowenzhai.ca/2018/04/15/OpenGL-Development-on-WSL-From-Setting-Up-to-Giving-Up-And-What-I-Learned/
A response from the WSL repo states that it may/may not work
https://github.com/microsoft/WSL/issues/2855
However, advanced opengl apps can definitely run under WSL!
Demo
The demo can be found here
Setup
The demo includes scripts for installing the following
Some dependencies to install
sudo apt install mesa-utils
sudo apt-get install x11-apps
sudo apt install clang
sudo apt-get install libglfw3
sudo apt-get install libglfw3-dev
On the desktop, install MobaXterm, which has a X server for displaying graphics from WSL
Test
Run the following to see if it works:
export DISPLAY=:0
xeyes
Now compile your program with the flags
-lX11 -lGL `pkg-config --static --libs glfw3`
In your opengl code, DO NOT INITIALIZE THE CORE! Comment it out
//glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
Now run your program including the environment variable to tell opengl to run with 3.3
MESA_GL_VERSION_OVERRIDE=3.3
For example,
MESA_GL_VERSION_OVERRIDE=3.3 ./test_program
Now you can run opengl applications under WSL! :)
Let me know if this works for you / or you encounter problems!

Wag The Dog (1997) Robert De Niro, Dustin Hoffman, Anne Heche, Woody Harrelson, Denis Leary, Andrea Martin, Willie Nelson, Suzie Plakson, Kirsten Dunst, William H. Macy, Craig T. Nelson. Directed by Barry Levinson. Rated R, 4 stars (out of five stars)
Review by Ed Johnson-Ott, NUVO Newsweekly www.nuvo-online.com/film/ Archive reviews at http://us.imdb.com/M/reviews_by?Edward+Johnson-ott
In politics, image is absolutely everything. Early in "Wag The Dog," someone challenges a top-level Presidential spin doctor about truth and he snaps "The truth? I'll tell you about truth. I saw the first draft of the Warren Commission Report. It said Kennedy was killed by a drunk driver." "Wag The Dog" is a hilarious black comedy about people so far removed from morals that questions of right or wrong never even enter their minds. Their only consideration is the effectiveness of their elaborate deceptions, and who gets a cut of the merchandising profits. Cynical? Of course, but Barry Levinson's crackerjack direction maintains such a giddy momentum that there's really no time to reflect on how awful these people are.  Here's the set-up. 11 days before the election, the incumbent President, who has enjoyed a 17% lead in the polls, is accused of hitting on an underage girl during a White House tour. Within hours, his challenger (Craig T. Nelson) has crafted devastating new TV ads, set to the tune of "Thank Heavens For Little Girls." Quickly, Presidential assistant Winifred Ames (Anne Heche) calls in damage control expert Conrad Brean (Robert De Niro,) who reasons that the only way for the President to be re-elected is if they create a crisis big enough to divert the nation's attention from the scandal. Perhaps a war, maybe with Albania. "Why Albania?" asks Ames. "Why not," laughs Brean. To orchestrate the pretend war, he enlists the aid of Hollywood producer Stanley Motss (Dustin Hoffman,) who is more than happy to help. "You know, there's not an Academy Award for producers," he moans, "Why is that? Do they think these things produce themselves?" Motss quickly plots out the scenario for the crisis, then pulls together his experts to work on the really important stuff; the war's official slogan, theme song and merchandising tie-ins. When "that yellow ribbon business" is mentioned, Ames interrupts to explain that the yellow ribbons were a naturally occurring phenomenon. She stops short though, when she notices Brean smiling wearily at her naiveté. And so the scam begins, with Brean instructing a White House Press Secretary to tell reporters that there is absolutely no truth to the rumors about problems in Albania relating to the B-3 bomber. When reminded that there is no B-3 bomber, Brean smiles confidently and says, "Exactly." The White House press corps dutifully responds to the bait, and within hours the nation is riveted to their TV sets, watching the latest on the crisis in Albania. David Mamet and Hilary Henkin's screenplay, based on the book by Larry Beinhart, is incredibly slick and fast-moving, operating on the assumption that movie-goers are savvy enough to roll with the concept.  Barry Levinson is a uneven director, turning out a few great works ("Rain Man") and some real dogs ("Toys",) but he's in top form here. He shot "Wag The Dog" in just 29 days, and the film has an immediacy that keeps the proceedings buoyant. His camera work displays a breezy confidence and a great sense of play. It's obvious the director was having a wonderful time turning out this wicked little film. Of course, it would be hard not to have fun with a cast like this. Anne Heche has a beguiling effervescence as the president's assistant. Winifred Ames may be new to deception at such a massive scale, but she hops right in and does her part. Robert De Niro exudes an ominous confidence as the man making the big decisions. His exact title is never divulged; you simply understand that when things go wrong, he's the guy you call to fix them. His role is much like Harvey Keitel's suave mob character in "Pulp Fiction," which makes perfect sense in this perverse context. Adding to the lunacy is Woody Harrelson in a deliciously twisted cameo as the designated hero for the bogus war. But despite the fine performances of the rest of the cast, it's Dustin Hoffman who steals the show with his Oscar-worthy portrayal of producer Stanley Motss. Rich, spoiled and self-obsessed, Motss is a fascinating character. Mid-way through the film, when the opposition catches on and orchestrates a televised announcement that the war has ended, Motss explodes, shouting "Over?! This war isn't over until I say it's over!" To Hoffman's credit, you don't doubt him for a second. Skirting the line between preposterousness and uncomfortable plausibility, "Wag The Dog" is a nightmarish delight that invites comparisons to such great satires as "Network" and "Dr. Strangelove." Prepare to laugh yourself silly, and let's all pray that the film is less true than it seems to be.

Everyday, family members and friends of COVID patients are tapping into all their contacts earnestly hoping to find a recovered person who is willing to donate plasma. Convalescent plasma therapy is one of the options explored to save some patients.
Transfusion medicine specialist Dr. Hitesh Kumar, also head of the blood bank at KIMS, explained about who all can donate plasma, how many times a person can donate plasma, and if there will be any changes to one’s health after the donation.
Plasma from those who recovered from COVID-19 contains antibodies that neutralise coronavirus. It is expected that the mortality rate might come down and patients will recover when plasma filled with the neutralising antibodies are infused into them. The process is still in clinical trial stages at Gandhi Hospital. However, it is increasingly opted at private hospitals, and thus, the flood of requests from family members desperate to save their loved ones.Because you fought the infection, your plasma now contains COVID-19 antibodies. These antibodies provided one way for your immune system to fight the virus when you were sick, so your plasma may be able to be used to help others fight off
the disease.
Convalescent refers to anyone recovering from a disease. Plasma is the yellow, liquid part of blood that contains antibodies. Antibodies are proteins made by the body in response to infections. Convalescent plasma from patients who have already recovered from coronavirus disease 2019 (COVID-19) may contain antibodies against COVID-19. Giving this convalescent plasma to hospitalized people currently fighting COVID-19 may help them recover. FDA has issued an emergency use authorization for convalescent plasma to be used in hospitalized COVID-19 patients and is being investigated for the treatment of COVID-19 because there is no approved treatment for this disease. Based on scientific evidence available, the FDA concluded this product may be effective in treating COVID-19 and that the known and potential benefits of the product outweigh the known and potential risks of the product in hospitalized COVID-19 patients.
I Have Fully Recovered From COVID-19. Am I Eligible to Donate Plasma?
People who have fully recovered from COVID-19 for at least two weeks are encouraged to consider donating plasma, which
may help save the lives of other patients. COVID-19 convalescent plasma must only be collected from recovered
individuals if they are eligible to donate blood. Individuals must have had a prior diagnosis of COVID-19 documented by
a laboratory test and meet other donor qualifications. Individuals must have complete resolution of symptoms for at
least 14 days prior to donation. A negative lab test for active COVID-19 disease is not necessary to qualify for
donation.
I Haven’t Had COVID-19. What Can I Do to Help?
You can consider donating blood! One blood donation can save up to three lives. The COVID-19 pandemic has caused
unprecedented challenges to the U.S. blood supply. Donor centers have experienced a dramatic reduction in donations due
to the implementation of social distancing and the cancellation of blood drives. Blood is needed every day to provide
lifesaving treatments to a variety of patients. You can help ensure that blood continues to be available for patients by
finding a blood donor center near you to schedule your donation. Several sites also have information about donating
plasma.

Eco Lab compiles out of the box on OSX using the Mac OSX Dev Tools package, which is available for free download from http://connect.apple.com
You need to make a choice whether you want to run Eco Lab as a native Aqua application, or as an X-windows application under the XFree86 server software. The only real disadvantage to using Aqua is that at the time of writing, BLT is not available for Aqua. This means in particular that the plot, histogram and display widgets will not work. Also note that the author does not have access to the console of a MacOS machine, so Aqua mode hasn't been supported for a while. If any MacOS user wishes to step up to maintaining the Aqua interface, please contact Russell Standish on hpcoder@sourceforge.net.

About
Who I am
David Puerto
UX
Engineer.
UX / UI Designer.
Prototyper.
CSS Specialist.
Cool, literate, human person. I don't have any children, nor any children on the way. I am strongly considering returning to college.
who I am
Born in '84 & raised across the United States, I live for those who've gone before me, am drawn to different cultures, and I promote minimalist idealism as I work towards producing a meaningful aesthetic. I live by the mantra "Be good to those around you," "I am my brothers' keeper," and I practice "Leave it better than you found it." Bespoke work is my speciality and I thrive off props from brainchild to launch.
what I do
As UX Engineer I graffiti up whiteboards, work nimbly across the modern JavaScript toolchain prototyping towards implementation, and I specialize in scalable CSS architecture. I strive to purposefully distill complex problems into elegant web-based solutions, producing beautifully engaging experiences. I take wireframes from initial scribble and explore design through varying degrees of prototypical fidelity. I manage design systems, implement user interfaces, and commit front-end skullduggery. I have presented my work at design meetups and code schools and have routinely consulted in New York, Atlanta, and Seattle between 2011-Present. In 2015 I was featured on the front page of GeekWire for participating in [and ultimately winning] Seattle's largest hackathon to date alongside my brilliant team of crucibled leaders: SpaceLabForever; cue the hand signals.

I was previously at Facebook where I worked on FBIDE codenamed Lyric: the zero-install, cloud-based IDE that was well-loved and impacted a significant number of Facebook engineers between 2013-2017. I would love to work as a UX Designer for Codepen and Github (esp Atom/VS Code) and SpaceX. Over the last decade, I've joined design and engineering teams and contributed to the outcome of a plethora of internal and customer facing tools. While I love being a remote consultant, I am especially happy to serve on staff at major brands as I continue to grow in this discipline. I dedicated my early career to a federal organization assisting non-profits in rural Kentucky carry out their missions and impacting the lives of people who I care deeply about.

where you'll find me
When I'm not geeking out, I'm training for life. I love endurance athletics, weight training, and extreme sports. Running and swimming long, hard, and fast are my jam. They provide me the solace to perform introspection, forgive myself and others for transgressions, seek peace from material things, and healing that I need: accepting my past, and letting go of things that I have clung to for far too long. I spend those hours thanking God for my humanity, my life, and those around me and those I seek to plot my next escapes with. In 2018 I spent January and Feburary in Japan (Japanuary) with some of the friends I've held onto throughout my lifetime. My brothers. My spirit. People from which I feel I'm cut from the same cloth and can recognize and shape and grow with one another. So thankful they are home. Catch me at the downtown library or thrifting for zombie bashing supplies online and in a second-hand stores. Survival skills baby. Discourses on purpose and the greater good? You bet. Finding ways to save rather than spend? Check. Roller rinks, skateparks, secret baches, mountains, jumping out of airplanes without anyone's genitals creepings up behind me, how else do you exit a perfectly good airplane? SCUBA, yup, Red Cross Lifeguarding - Sí como no! Banyas and yoga studios, shooting ranges, obstacle courses, or sharing a seltzer water and wrenching on some sort of project or grabbing paint and getting up with a hommie. Ya tú sabes.
You can find me on social media such as: CodePen and GitHub, cookin' it up on MapMyRun, competing on Stava, gettin' high on PeakBagger, goin' places with GaiaGPS, handlin' it on ChessWithFriends, and placing tiles of coquesttish fantasy upon WordsWithFriends. Oh, I'll snapchat occasionally too. What'sapp! For work inquiries, hackathon-related information, speaking engagements, or to help publish my novel, please send me a dedicated email. I'm a sucker for a green tea matcha latte at Cherry Street Public House.


Mum, 33, describes the constant agony of living with 'suicide disease'
Toni Lea Lawrence went without medication when she was pregnant with her first child, however the pain from her trigeminal neuralgia condition is now too severe for her to have another baby
by Matthew Dresch, https://www.mirror.co.uk/authors/matthew-dresch/A mum has spoken out about the excruciating pain she suffers on a daily basis because of a condition that's been dubbed 'suicide disease'.
Toni Lea Lawrence, 33, has to take powerful medication to deal with the chronic pain, leaving her unable to have another baby.
Mrs Lawrence, from Australia, weaned herself off the pain pills in order to fulfil her dream of becoming a mum when she had her first child.
However, the pain is now so bad she cannot face another pregnancy without any drugs.
The senior paralegal had to give up her job because of her agonising condition.
It all started in March 2010, when she suffered a wave of searing pain and lost control of her left side at work.
According to Yahoo News , she said: “I was sitting at my desk reading emails and my first thought was that I was having a stroke because I was in so much pain and my left side was struggling to work, and I could barely talk."
She rushed to a nearby GP surgery in a panic after a colleague said her face looked different.
A doctor gave her pain relief and sent her for an MRI scan, believing she had a brain tumour.
However, Mrs Lawrence later found out she had trigeminal neuralgia (TN), which is commonly known as 'suicide disease'.
She said the condition caused agony on her left side and compared the pain to her teeth being ripped out with fishing wire.
The mum added: "It is triggered by stress, touching my face, really cold weather , really hot weather and wind hitting my face.”
The pain associated with the disease means that most sufferers are unable to have children - because they must come off medication for their pregnancy.
However, Mrs Lawrence was so keen to have a baby with her husband Kieran, 32, that she came off her medication.
She suffered increasingly severe pain after the fifth week of her pregnancy.
Her contractions began after she fell down the stairs at 35 weeks, although doctors held off Theo's birth for one more week.
The tot, now two, was delivered via c-section and his mum was finally able to take pain relief again after he was born.
Although she would love to have more children, Mrs Lawrence says her pain has now become too much to consider a drug-free pregnancy.


Global Action Project's mission is to work with young people most affected by injustice to build the knowledge, tools, and relationships needed to create media for community power, cultural expression, and political change.

Defence Forces battalion back in Dublin after Lebanon deployment
Hundreds of members of the Defence Forces have arrived back in Ireland following deployment to Lebanon.
Mothers brought sons and daughters in fancy dress to the arrivals hall at Dublin airport on Monday.
Tricolours were flying as well as balloons which said “welcome home”.
Children wore t-shirts which said: “Get out of my way, dad’s coming home today.”
The 114th Infantry Battalion deployed in May to South Lebanon as part of the peacekeeping force deployed by the UN.
The force was originally deployed to monitor the cessation of hostilities with Israel in 1978 and is now involved in humanitarian work.

1. Amnesty Scheme to provide relief to taxpayers regarding late fees for pending returns
To cap late fee for non-furnishing of Form GSTR 3B for tax periods from July 2017 to April 2021 to INR 500 (INR 250 each for CGST and SGST) per return for taxpayers who did not have any tax liability for the said tax period and INR 1,000 (INR 500 each for CGST and SGST) for other taxpayers. Such reduced rate of late fee would apply if the return for these tax periods is furnished between 1 June 2021 to 31 August 2021.
2. Rationalization of late fee
To reduce burden of late fee on taxpayers for delay in filing Form GSTR 1 and Form GSTR 3B, the upper cap of late fee to be rationalized as per below table :
| Nil tax liability | INR 500 (INR 250 each for CGST and SGST) |
| Taxpayers having Annual Aggregate Turnover (AATO) upto INR 1.5 Crores | INR 2,000 (INR 1,000 each for CGST and SGST) |
| Taxpayers having AATO between INR 1.5 Crores to INR 5 Crores | INR 5,000 (INR 2,500 each for CGST and SGST) |
| Taxpayers having AATO above INR 5 Crores | INR 10,000 (INR 5,000 each for CGST and SGST) |
Further late fee payable for delayed filing of Form GSTR 7 to be reduced to INR 50 per day (INR 25 each for CGST and SGST) and capped to maximum of INR 2,000 (INR 1,000 each for CGST and SGST) per return.
3. Further relaxations to taxpayers in addition to relaxations already provided vide notification dated 1 May 2021

A stable release will always have a minor number that is an even number. This implies that you should be able to upgrade to a new version of the library with the same major and minor numbers without fear that any of the APIs have changed. The only changes that should be made to a stable branch are bug fixes and under some circumstances, additional functionality (e.g. adding support for a new device).
If major version number has changed, this implies that the required versions of gcc and binutils have changed. Consult the README file in the toplevel directory of the AVR Libc source for which versions are required.
The major version number of a development series is always the same as the last stable release.
The minor version number of a development series is always an odd number and is 1 more than the last stable release.
The patch version number of a development series is always 0 until a new branch is cut at which point the patch number is changed to 90 to denote the branch is approaching a release and the date appended to the version to denote that it is still in development.
All versions in development in cvs will also always have the date appended as a fourth version number. The format of the date will be YYYYMMDD.
So, the development version number will look like this:
While a pre-release version number on a branch (destined to become either 1.2 or 2.0) will look like this:
The information in this section is only relevant to AVR Libc developers and can be ignored by end users.
- Note:
- In what follows, I assume you know how to use cvs and how to checkout multiple source trees in a single directory without having them clobber each other. If you don't know how to do this, you probably shouldn't be making releases or cutting branches.
The following steps should be taken to cut a branch in cvs:
- Check out a fresh source tree from cvs HEAD.
- Update the NEWS file with pending release number and commit to cvs HEAD:
Change "Changes since avr-libc-<last_release>:" to "Changes in avr-libc-<this_relelase>:". - Set the branch-point tag (setting <major> and <minor> accordingly):
'cvs tag avr-libc-<major>_<minor>-branchpoint' - Create the branch:
'cvs tag -b avr-libc-<major>_<minor>-branch' - Update the package version in configure.ac and commit configure.ac to cvs HEAD:
Change minor number to next odd value. - Update the NEWS file and commit to cvs HEAD:
Add "Changes since avr-libc-<this_release>:" - Check out a new tree for the branch:
'cvs co -r avr-libc-<major>_<minor>-branch' - Update the package version in configure.ac and commit configure.ac to cvs branch:
Change the patch number to 90 to denote that this now a branch leading up to a release. Be sure to leave the <date> part of the version. - Bring the build system up to date by running bootstrap and configure.
- Perform a 'make distcheck' and make sure it succeeds. This will create the snapshot source tarball. This should be considered the first release candidate.
- Upload the snapshot tarball to savannah.
- Announce the branch and the branch tag to the avr-libc-dev list so other developers can checkout the branch.
- Note:
- CVS tags do not allow the use of periods ('.').
A stable release will only be done on a branch, not from the cvs HEAD.
The following steps should be taken when making a release:
- Make sure the source tree you are working from is on the correct branch:
'cvs update -r avr-libc-<major>_<minor>-branch' - Update the package version in configure.ac and commit it to cvs.
- Update the gnu tool chain version requirements in the README and commit to cvs.
- Update the ChangeLog file to note the release and commit to cvs on the branch:
Add "Released avr-libc-<this_release>." - Update the NEWS file with pending release number and commit to cvs:
Change "Changes since avr-libc-<last_release>:" to "Changes in avr-libc-<this_relelase>:". - Bring the build system up to date by running bootstrap and configure.
- Perform a 'make distcheck' and make sure it succeeds. This will create the source tarball.
- Tag the release:
'cvs tag avr-libc-<major>_<minor>_<patch>-release' - Upload the tarball to savannah.
- Update the NEWS file, and commit to cvs:
Add "Changes since avr-libc-<major>_<minor>_<patch>:" - Generate the latest documentation and upload to savannah.
- Announce the release.
The following hypothetical diagram should help clarify version and branch relationships.

Compare incomparable: PostgreSQL vs Mysql vs Mongodb
29 Dec 2015As such, there’s really no “standard” benchmark that will inform you about the best technology to use for your application. Only your requirements, your data, and your infrastructure can tell you what you need to know.
NoSql is everywhere and we can’t escape from it (although I can’t say we want to escape). Let’s leave the question about reasons outside this text, and just note one thing - this trend isn’t related only to new or existing NoSql solutions. It has another side, namely the schema-less data support in traditional relational databases. It’s amazing how many possibilities hiding at the edge of the relational model and everything else. But of course there is a balance that you should find for your specific data. It can’t be easy, first of all because it’s required to compare incomparable things, e.g. performance of a NoSql solution and traditional database. Here in this post I’ll make such attempt and show the comparison of jsonb in PostgreSQL, json in Mysql and bson in Mongodb.

Breaking news:
- PostgreSQL 9.4 - a new data type
jsonb
with slightly extended support in the upcoming release PostgreSQL 9.5 - Mysql 5.7.7 - a new data type
json
and several other examples (I’ll talk about them later). Of course these data types supposed to be binary, which means great performance. Base functionality is equal across the implementations because it’s just obvious CRUD. And what is the oldest and almost cave desire in this situation? Right, performance benchmarks! PostgreSQL and Mysql were choosen because they have quite similar implementation of json support, Mongodb - as a veteran of NoSql. An EnterpriseDB research is slightly outdated, but we can use it as a first step for the road of a thousand li. A final goal is not to display the performance in artificial environment, but to give a neutral evaluation and to get a feedback.
Some details and configurations
The pg_nosql_benchmark
from EnterpriseDB suggests an obvious approach - first of all the required amount of records must be generated using different kinds of
data and some random fluctuations. This amount of data will be saved into the database, and we will perform several kinds of queries over it.
pg_nosql_benchmark
doesn’t have any functional to work with Mysql, so I had to implement it similar to PostgreSQL.
There is only one tricky thing with Mysql - it doesn’t support json indexing directly, it’s required to create virtual columns and create index on them.
Speaking of details, there was one strange thing in pg_nosql_benchmark
. I figured out that few types of generated records
were beyond the 4096 bytes limit for mongo shell, which means these records were
just dropped out. As a dirty hack for that we can perform the inserts from a js
file (and btw, that file must be splitted into the series of chunks
less than 2GB).
Besides, there are some unnecessary time expenses, related to shell client, authentication and so on. To estimate and exclude them I have to perform corresponding amount of “no-op” queries for all databases (but they’re actually pretty small).
After all modifications above I’ve performed measurements for the following cases:
- PostgreSQL 9.5 beta1, gin
- PostgreSQL 9.5 beta1, jsonb_path_ops
- PostgreSQL 9.5 beta1, jsquery
- Mysql 5.7.9
- Mongodb 3.2.0 storage engine WiredTiger
- Mongodb 3.2.0 storage engie MMAPv1
Each of them was tested on a separate m4.xlarge
amazon instance with the ubuntu 14.04 x64
and default configurations,
all tests were performed for 1000000 records. And you shouldn’t forget about the instructions for the jsquery
-
bison
, flex
, libpq-dev
and postgresql-server-dev-9.5
must be installed. All results were saved in json file,
we can visualize them easily using matplotlib (see here).
Besides that there was a concern about durability. To take this into account I made few specific configurations (imho some of them are real, but some of them are quite theoretical, because I don’t think someone will use them for production systems):
- Mongodb 3.2.0 journaled (writeConcern j: true)
- Mongodb 3.2.0 fsync (transaction_sync=(enabled=true,method=fsync))
- PostgreSQL 9.5 beta 1, no fsync (fsync=off)
- Mysql 5.7.9, no fsync (innodb_flush_method=nosync)
Results
All charts presented in seconds (if they related to the time of query execution) or mb (if they related to the size of relation/index). Thus, for all charts the smaller value is better.
Select
Insert
Insert with configurations
Update
Update is another difference between my benchmarks and pg_nosql_benchmark
. It can bee seen, that Mongodb is an obvious
leader here - mostly because of PostgreSQL and Mysql restrictions, I guess, when to update one value you must override an entire field.
Update with configurations
As you can guess from documentation and this answer,
writeConcern j:true
is the highest possible transaction durability level (on a single server),
that should be equal to configuration with fsync
.
I’m not sure about durability, but fsync
is definitely slower for update operations here.
Table/index size
I have a bad feeling about this
Performance measurement is a dangerous field especially in this case. Everything described above can’t be a completed benchmark, it’s just a first step to understand current situation. We’re working now on ycsb tests to make more finished measurements, and if we’ll get lucky we’ll compare the performance of cluster configurations.

Distribution packages, package management, and deploying applications¶
Just as the “big” Python, MicroPython supports creation of “third party” packages, distributing them, and easily installing them in each user’s environment. This chapter discusses how these actions are achieved. Some familiarity with Python packaging is recommended.
Overview¶
Steps below represent a high-level workflow when creating and consuming packages:
Python modules and packages are turned into distribution package archives, and published at the Python Package Index (PyPI).
upip package manager can be used to install a distribution package on a MicroPython port with networking capabilities (for example, on the Unix port).
For ports without networking capabilities, an “installation image” can be prepared on the Unix port, and transferred to a device by suitable means.
For low-memory ports, the installation image can be frozen as the bytecode into MicroPython executable, thus minimizing the memory storage overheads.
The sections below describe this process in details.
Distribution packages¶
Python modules and packages can be packaged into archives suitable for transfer between systems, storing at the well-known location (PyPI), and downloading on demand for deployment. These archives are known as distribution packages (to differentiate them from Python packages (means to organize Python source code)).
The MicroPython distribution package format is a well-known tar.gz format, with some adaptations however. The Gzip compressor, used as an external wrapper for TAR archives, by default uses 32KB dictionary size, which means that to uncompress a compressed stream, 32KB of contiguous memory needs to be allocated. This requirement may be not satisfiable on low-memory devices, which may have total memory available less than that amount, and even if not, a contiguous block like that may be hard to allocate due to memory fragmentation. To accommodate these constraints, MicroPython distribution packages use Gzip compression with the dictionary size of 4K, which should be a suitable compromise with still achieving some compression while being able to uncompressed even by the smallest devices.
Besides the small compression dictionary size, MicroPython distribution
packages also have other optimizations, like removing any files from
the archive which aren’t used by the installation process. In particular,
upip package manager doesn’t execute setup.py
during installation
(see below), and thus that file is not included in the archive.
At the same time, these optimizations make MicroPython distribution
packages not compatible with CPython’s package manager, pip
.
This isn’t considered a big problem, because:
Packages can be installed with upip, and then can be used with CPython (if they are compatible with it).
In the other direction, majority of CPython packages would be incompatible with MicroPython by various reasons, first of all, the reliance on features not implemented by MicroPython.
Summing up, the MicroPython distribution package archives are highly optimized for MicroPython’s target environments, which are highly resource constrained devices.
upip
package manager¶
MicroPython distribution packages are intended to be installed using the upip package manager. upip is a Python application which is usually distributed (as frozen bytecode) with network-enabled MicroPython ports <MicroPython port>. At the very least, upip is available in the MicroPython Unix port.
On any MicroPython port providing upip, it can be accessed as following:
import upip
upip.help()
upip.install(package_or_package_list, [path])
Where package_or_package_list is the name of a distribution package to install, or a list of such names to install multiple packages. Optional path parameter specifies filesystem location to install under and defaults to the standard library location (see below).
An example of installing a specific package and then using it:
>>> import upip
>>> upip.install("micropython-pystone_lowmem")
[...]
>>> import pystone_lowmem
>>> pystone_lowmem.main()
Note that the name of Python package and the name of distribution
package for it in general don’t have to match, and oftentimes they
don’t. This is because PyPI provides a central package repository
for all different Python implementations and versions, and thus
distribution package names may need to be namespaced for a particular
implementation. For example, all packages from micropython-lib
follow this naming convention: for a Python module or package named
foo
, the distribution package name is micropython-foo
.
For the ports which run MicroPython executable from the OS command prompts (like the Unix port), upip can be (and indeed, usually is) run from the command line instead of MicroPython’s own REPL. The commands which corresponds to the example above are:
micropython -m upip -h
micropython -m upip install [-p <path>] <packages>...
micropython -m upip install micropython-pystone_lowmem
[TODO: Describe installation path.]
Cross-installing packages¶
For MicroPython ports <MicroPython port> without native networking capabilities, the recommend process is “cross-installing” them into a “directory image” using the MicroPython Unix port, and then transferring this image to a device by suitable means.
Installing to a directory image involves using -p
switch to upip:
micropython -m upip install -p install_dir micropython-pystone_lowmem
After this command, the package content (and contents of every dependency
packages) will be available in the install_dir/
subdirectory. You
would need to transfer contents of this directory (without the
install_dir/
prefix) to the device, at the suitable location, where
it can be found by the Python import
statement (see discussion of
the upip installation path above).
Cross-installing packages with freezing¶
For the low-memory MicroPython ports <MicroPython port>, the process described in the previous section does not provide the most efficient resource usage,because the packages are installed in the source form, so need to be compiled to the bytecome on each import. This compilation requires RAM, and the resulting bytecode is also stored in RAM, reducing its amount available for storing application data. Moreover, the process above requires presence of the filesystem on a device, and the most resource-constrained devices may not even have it.
The bytecode freezing is a process which resolves all the issues mentioned above:
The source code is pre-compiled into bytecode and store as such.
The bytecode is stored in ROM, not RAM.
Filesystem is not required for frozen packages.
Using frozen bytecode requires building the executable (firmware) for a given MicroPython port from the C source code. Consequently, the process is:
Follow the instructions for a particular port on setting up a toolchain and building the port. For example, for ESP8266 port, study instructions in
ports/esp8266/README.md
and follow them. Make sure you can build the port and deploy the resulting executable/firmware successfully before proceeding to the next steps.Build MicroPython Unix port and make sure it is in your PATH and you can execute
micropython
.Change to port’s directory (e.g.
ports/esp8266/
for ESP8266).Run
make clean-frozen
. This step cleans up any previous modules which were installed for freezing (consequently, you need to skip this step to add additional modules, instead of starting from scratch).Run
micropython -m upip install -p modules <packages>...
to install packages you want to freeze.Run
make clean
.Run
make
.
After this, you should have the executable/firmware with modules as the bytecode inside, which you can deploy the usual way.
Few notes:
Step 5 in the sequence above assumes that the distribution package is available from PyPI. If that is not the case, you would need to copy Python source files manually to
modules/
subdirectory of the port port directory. (Note that upip does not support installing from e.g. version control repositories).The firmware for baremetal devices usually has size restrictions, so adding too many frozen modules may overflow it. Usually, you would get a linking error if this happens. However, in some cases, an image may be produced, which is not runnable on a device. Such cases are in general bugs, and should be reported and further investigated. If you face such a situation, as an initial step, you may want to decrease the amount of frozen modules included.
Creating distribution packages¶
Distribution packages for MicroPython are created in the same manner
as for CPython or any other Python implementation, see references at
the end of chapter. Setuptools (instead of distutils) should be used,
because distutils do not support dependencies and other features. “Source
distribution” (sdist
) format is used for packaging. The post-processing
discussed above, (and pre-processing discussed in the following section)
is achieved by using custom sdist
command for setuptools. Thus, packaging
steps remain the same as for the standard setuptools, the user just
needs to override sdist
command implementation by passing the
appropriate argument to setup()
call:
from setuptools import setup
import sdist_upip

The sdist_upip.py module as referenced above can be found in micropython-lib: https://github.com/micropython/micropython-lib/blob/master/sdist_upip.py
Application resources¶
A complete application, besides the source code, oftentimes also consists of data files, e.g. web page templates, game images, etc. It’s clear how to deal with those when application is installed manually - you just put those data files in the filesystem at some location and use the normal file access functions.
The situation is different when deploying applications from packages - this is more advanced, streamlined and flexible way, but also requires more advanced approach to accessing data files. This approach is treating the data files as “resources”, and abstracting away access to them.
Python supports resource access using its “setuptools” library, using
pkg_resources
module. MicroPython, following its usual approach,
implements subset of the functionality of that module, specifically
pkg_resources.resource_stream(package, resource)
function.
The idea is that an application calls this function, passing a
resource identifier, which is a relative path to data file within
the specified package (usually top-level application package). It
returns a stream object which can be used to access resource contents.
Thus, the resource_stream()
emulates interface of the standard
open() function.
Implementation-wise, resource_stream()
uses file operations
underlyingly, if distribution package is install in the filesystem.
However, it also supports functioning without the underlying filesystem,
e.g. if the package is frozen as the bytecode. This however requires
an extra intermediate step when packaging application - creation of
“Python resource module”.
The idea of this module is to convert binary data to a Python bytes
object, and put it into the dictionary, indexed by the resource name.
This conversion is done automatically using overridden sdist
command
described in the previous section.
Let’s trace the complete process using the following example. Suppose your application has the following structure:
my_app/
__main__.py
utils.py
data/
page.html
image.png
__main__.py
and utils.py
should access resources using the
following calls:
import pkg_resources
pkg_resources.resource_stream(__name__, "data/page.html")
pkg_resources.resource_stream(__name__, "data/image.png")
You can develop and debug using the MicroPython Unix port as usual. When time comes to make a distribution package out of it, just use overridden “sdist” command from sdist_upip.py module as described in the previous section.
This will create a Python resource module named R.py
, based on the
files declared in MANIFEST
or MANIFEST.in
files (any non-.py
file will be considered a resource and added to R.py
) - before
proceeding with the normal packaging steps.
Prepared like this, your application will work both when deployed to filesystem and as frozen bytecode.
If you would like to debug R.py
creation, you can run:
python3 setup.py sdist --manifest-only
Alternatively, you can use tools/mpy_bin2res.py script from the MicroPython distribution, in which can you will need to pass paths to all resource files:
mpy_bin2res.py data/page.html data/image.png

The grid of the future will require treating data differently; leveraging metadata and performing analysis locally to process the mountain of new data available from new technologies. Traditional headend systems, illustrated on the left below, have relied on relatively few sources of field information. New asset classes on the grid (AMI, smart inverters, PMUs, etc.) have added large amounts of data that can quickly and accurately describe the state of the power system. Traditional headend systems were not designed to process this increased volume of information as quickly as is needed to react to current operational scenarios and fully realize the benefits of these new grid edge assets.
Information no longer needs to go to the central system to enable decision making. Federated local data can be made securely available between assets at the grid edge to complement and enhance operations. OpenFMB nodes, shown as blue hexagons on the right of the figure below, host applications that analyze information to develop a higher resolution of situational awareness, and provide the ability to affect local control in coordination with other operational decision making.
Figure 1: Traditional system (left) and OpenFMB system (right)
OpenFMB provides the ability to leverage new along with existing grid assets to ensure that the future power system is more resilient, reliable, safe, secure, and cost effective than traditional approaches. The OpenFMB reference architecture offers best practices and a variety of solution options that a utility service provider can draw upon in defining its specific OpenFMB implementation. Together, the business oriented framework approach and reference architecture support a utility service provider’s procurement process.
The OpenFMB framework consists of a top-down approach moving from business case to use case, data modeling (UML and XSD/IDL), and then implementation approaches (apps/adapters, test/field and maintenance). The reference architecture includes operational, management services, and security best practices.
Figure 2: Framework Lifecycle
OpenFMB nodes are the deployment unit, and range in form from virtual software environments to a variety of physical hardware based options. The following diagram illustrates representative operational interactions between OpenFMB nodes, shown in yellow. Applications providing services, native controllers for their related field equipment, adapters to existing field controllers and their related equipment, and adapters to other systems such as central systems are shown in blue. In green are field equipment related to their native controllers as well as existing systems such as existing field controllers and their related equipment and other existing systems such as central systems.
Shown in red are Industrial Internet of Things (IIoT) publish-subscribe middleware instances that provides authorized communications within a node without messages leaving the node as well as authorized communications between nodes. These communications utilize data profiles based on existing standards, such as IEC’s Common Information Model (CIM), for the semantic data model as developed through the framework approach. In this way, OpenFMB deployments can be scaled independently to meet specific needs without a system-wide rollout. For resiliency, peer-to-peer publish-subscribe protocols are commonly used.

In March 2015, the Smart Grid Interoperability Panel (SGIP) formally kicked-off its OpenFMB effort to foster field interoperability drawing upon Duke Energy’s previous Coalition of the Willing I and Distributed Intelligence Platform work. By the 2015 SGIP Annual Conference in November, three microgrid use cases had been developed and demonstrated: optimization, unscheduled islanding, and grid reconnection.
In February 2016, the first OpenFMB reference implementation, utilizing SGIP’s microgrid use cases at Duke Energy’s Mount Holly microgrid test center, was demonstrated at the 2016 DistribuTECH Conference by Duke Energy’s Coalition of the Willing II (COW-II) vendor partners. To advance interoperability among established and new technologies, the demonstration highlighted multiple technology options from 25 vendors with at least two independently developed implementations of each function.
For the annual SGIP Grid Modernization Summit in November 2016 the SGIP OpenFMB task force published a series of related foundational use cases that center on Distributed Energy Resources (DER) Circuit Segment Management for the active coordination of power systems equipment to DER, including a microgrid.
Figure 4: Example DER Circuit Segment Management Reference Implementation at Duke Energy
The DER Circuit Segment Management and other OpenFMB use cases listed below are planned to be implemented as pilot projects by several utilities.
The North American Energy Standards Board (NAESB) established a Retail Markets Quadrant Task Force, RMQ.26, to develop the OpenFMB framework and reference architecture document in parallel with SGIP’s OpenFMB effort. SGIP appointed a liaison to the task force so that the framework and reference architecture reflects the experiences and lessons from the initial business case, use case, data modeling, implementation, and SGIP Annual Conference interoperability demonstration activities.
OpenFMB was ratified by the North American Energy Standards Board on March 7, 2016. The official release is NAESB RMQ.26 Open Field Message Bus (OpenFMB) Model Business Practices. It is part of the version 3.1 bundle of all their standards released at the end of March.
Utilities and other members of NAESB have access to NAESB RMQ.26 OpenFMB. The lower center of www.naesb.org has a link "NAESB Copyright Policy & Access & Use of NAESB Standards” which goes to a page with a link in the middle center “NAESB Copyright Policy and Companies with Access to NAESB Standards Under the Copyright Policy” that lists entities with access to RMQ.26 OpenFMB. Ask your entity’s NAESB representative for access to RMQ.26 OpenFMB.

Base class for reference-counted objects.
All objects that have a reference-type have an associated shallow (polymorphic) assignment operator that simply changes the value of the reference. Furthermore, reference-types are safe, meaning that under no circumstances can a reference point to an invalid object. At any single point in time a reference can either refer to the null object or to a valid object.
The semantics for Reference types is defined by the DDS-PSM-Cxx class dds::core::Reference. In the context of this specification the semantics implied by the ReferenceType is mandatory, yet the implementation supplied as part of this standard is provided to show one possible way of implementing this semantics.
List of reference types:
Instances of reference types are created using C++ constructors. The trivial constructor is not defined for reference types; the only alternative to properly constructing a reference is to initialize it to a null reference by assigning dds::core::null.
Resource management for some reference types might involve relatively heavyweight operating-system resources (such as threads, mutexes, and network sockets) in addition to memory. These objects therefore provide a function close() that shall halt network communication (in the case of entities) and dispose of any appropriate operating-system resources.
Users of this PSM are recommended to call close on objects of all reference types once they are finished using them. In addition, implementations may automatically close objects that they deem to be no longer in use, subject to the following restrictions:

| dds::core::Reference< DELEGATE >::~Reference | ( | ) |
| bool dds::core::Reference< DELEGATE >::is_nil | ( | ) | const |
Check if the referenced object is nil.
In other words, check if the reference is pointing to a null object.
| bool dds::core::Reference< DELEGATE >::operator!= | ( | const null_type | nil | ) | const |
Special operator!= used to check if this reference object does not equal the dds::core::null reference.
The non-null-check can be done like this:
| bool dds::core::Reference< DELEGATE >::operator!= | ( | const R & | ref | ) | const |
| DELEGATE* dds::core::Reference< DELEGATE >::operator-> | ( | ) |
The operator->() is provided to be able to directly invoke functions on the delegate.
The decision to provide direct access to the delegate was motivated by the need for providing a way that was not invasive with respect to the CXXDDS API and yet would allow for vendor-specific extension. Thus vendor-specific extensions can be invoked on the Reference and on all its subclasses as follows:
| const DELEGATE* dds::core::Reference< DELEGATE >::operator-> | ( | ) | const |
The operator->() is provided to be able to directly invoke functions on the delegate.
The decision to provide direct access to the delegate was motivated by the need for providing a way that was not invasive with respect to the CXXDDS API and yet would allow for vendor-specific extension.

Special assignment operators that takes care of assigning dds::core::null to this reference.
When assigning null, there might be an associated garbage collection activity.
| Reference& dds::core::Reference< DELEGATE >::operator= | ( | const R & | rhs | ) |

Q: Why has the establishment failed us?
 Ronald Reagan first posed this question during the 1980 Presidential campaign, and Americans have been asking it themselves ever since. This is the final year of President Obama’s second term, so to cover his entire Presidency, let’s consider what the current administration has done over the past eight years.
Has the establishment failed us? Take a look at just a small sampling of what the Obama Administration has accomplished and decide for yourself.
-
President Obama’s first official act was to sign the Lilly Ledbetter Fair Pay Act into law, which helped to close the pay gap between men and women.
-
President Obama pushed through the American Recovery and Reinvestment Act. The stimulus package essentially prevented the United States from dipping back into recession. It created 1.6 million jobs a year for 4 years, and raised the nation’s economic output by 2 to 3 percent from 2009 to 2011. The package also improved 42,000 miles of roads and fixed or replaced 2,700 bridges. It cleaned up water supplies, created the school reforms of the Race to the Top program, and greatly expanded the use of renewable energy and broadband Internet service.
-
The Temporary Assets Relief Program (TARP) saved the financial and banking industries, and under President Obama’s leadership, virtually all of the “bailout” money was paid back.
-
The Home Affordable Refinance Program (HARP) and the Making Home Affordable Program help people impacted by the mortgage crisis keep their homes.
-
And perhaps President Obama’s crowning achievement, the Affordable Care Act (informally known as “Obamacare”), provides health insurance to 4.2 million people!
So, are people better off now than they were in 2009? Most Americans are. Here are some facts about the health of our economy:
- In 2009, unemployment reached a high of 10%; today it is 5%.
- We’ve had 73 months of private sector job growth, the longest period on record.
- The Dow Jones Industrial Average was below 7,000 points in 2009, today it is over 18,000.
- And contrary to what many people think, our federal deficit has declined by roughly three-quarters.
Is there more to do? Of course there is! And Hillary will continue to move our country forward, and fight for even more programs to help Americans who are struggling. Check out the detailed plans on her website.


An Insight is a single prediction for an asset. The Update
method returns an array of Insight objects. You can think of these as actionable trading signals, indicating the asset direction, magnitude, and confidence in the near future. All insights can take a weight parameter to set the desired weighting for the insight. If you change the cash of the algorithm, it will affect the orders, but not necessarily the insights.
The Portfolio Construction model consumes the Insight objects from the Alpha model. It's up to the Portfolio Construction model to define how Insight objects are converted into PortfolioTarget
objects. In the pre-built Portfolio Construction models, down insights translate to short-biased trades, up insights translate to long-biased trades, and flat insights usually close open positions, but this doesn't have to be the case in custom Portfolio Construction models.
Insight
objects have the following properties:
To create an Insight
, call the Insight
constructor.
# Insight(symbol, period, type, direction, magnitude=None, confidence=None, sourceModel=None, weight=None) insight = Insight("IBM", timedelta(minutes=20), InsightType.Price, InsightDirection.Up)
// new Insight(symbol, period, type, direction, magnitude=null, confidence=null, sourceModel=null, weight=null); var insight = new Insight("IBM", TimeSpan.FromMinutes(20), InsightType.Price, InsightDirection.Up);
In the Insight
constructor, the period
argument can be a timedelta
TimeSpan
object or a function that receives a DateTime
datetime
object and returns the expiry DateTime
datetime
. Some of the constructor arguments are optional to create the Insight
object, but some of the Portfolio Construction models may require these properties. To check which Insight
properties a Portfolio Construction model requires, see Supported Models.
You can also use the helper method to create Insight objects of the Price type.
# Insight.Price(symbol, period, direction, magnitude=None, confidence=None, sourceModel=None, weight=None) insight = Insight.Price("IBM", timedelta(minutes = 20), InsightDirection.Up) # Insight.Price(symbol, resolution, barCount, direction, magnitude=None, confidence=None, sourceModel=None, weight=None) insight = Insight.Price("IBM", Resolution.Minute, 20, InsightDirection.Up)
// new Insight(symbol, period, direction, magnitude=null, confidence=null, sourceModel=null, weight=null) var insight = Insight.Price("IBM", TimeSpan.FromMinutes(20), InsightDirection.Up); // new Insight(symbol, resolution, barCount, direction, magnitude=null, confidence=null, sourceModel=null, weight=null) var insight = Insight.Price("IBM", Resolution.Minute, 20, InsightDirection.Up);
In the Price
method, the period
argument can be a timedelta
TimeSpan
object, a DateTime
datetime
object, or a function that receives a DateTime
datetime
object and returns the expiry DateTime
datetime
.
Sometimes an algorithm's performance relies on multiple insights being traded together, like in pairs trading and options straddles. These types insights should be grouped. Insight groups signal to the Execution model that the insights need to be acted on as a single unit to maximize the alpha created.
To mark insights as a group, call the Insight.Group
method.
return Insight.Group(insight1, insight2, insight3);
return Insight.Group([insight1, insight2,insight3])
If an Alpha model in your algorithm emits an Insight to enter a position but it determines the trading opportunity has pre-maturely ended, you should cancel the Insight. For example, say you want your algorithm to enter a long position in a security when its Relative Strength Index (RSI) moves below 20 and then liquidate the position when the security's RSI moves above 30. If you emit an Insight that has a duration of 30 days when the RSI moves below 20 but the RSI moves above 30 in 10 days, you should cancel the Insight.
To cancel an Insight, call its Cancel
/Expire
method with the algorithm's Coordinated Universal Time (UTC).
self.insight.Cancel(algorithm.UtcTime)
_insight.Cancel(algorithm.UtcTime);
If you don't have a reference to the Insight you want to cancel, get it from the InsightManager.
When you cancel an insight, it's CloseTimeUtc
property is set to one second into the past.
