|
|
* The main tasks are: |
70 |
|
|
* - [1] Creates the Dynamic Graph device, the python interpreter, and the |
71 |
|
|
* Drivers |
72 |
|
|
* - [2] Ask the python interpreter to advertise its ROS services |
73 |
|
|
* - [3] Ask the drivers to initialize the communication with the hardware |
74 |
|
|
* - [4] Loads a yaml/urdf config file. |
75 |
|
|
* - [5] Advertise the ROS services start/stop dynamic graph |
76 |
|
|
* - [6] Wait for the ROS service start dynamic graph to be called |
77 |
|
|
* - [7] Spawn the first real time process that executes the following: |
78 |
|
|
* - [7.1] gets the sensor data using Drivers and saves them in the |
79 |
|
|
* shared std::map sensors |
80 |
|
|
* - [7.2] reads the control values in the shared std::map commands and |
81 |
|
|
* send them to the motors via the Drivers |
82 |
|
|
* - [8] Spawn the second real time process that executes the following: |
83 |
|
|
* - [8.1] passes the std::map sensors to the Device, which copies the data |
84 |
|
|
* to its output signals |
85 |
|
|
* - [8.2] gets the control values from the Device (which triggers the |
86 |
|
|
* evaluation of the dynamic graph) and copies them into |
87 |
|
|
* the shared std::map commands. |
88 |
|
|
* In this class we heavily depend on std::unique pointers in order to |
89 |
|
|
* initialize the DynamicGraph process and the hardware communication process |
90 |
|
|
* independently. |

To get the current Binance Crypto Margin Rate data, index the MarginInterestRates property of the current Slice with the Crypto Future Symbol. Slice objects deliver unique events to your algorithm as they happen, but the Slice may not contain data for your security at every time step. To avoid issues, check if the Slice contains the data you want before you index it.
def OnData(self, slice: Slice) -> None: if self.symbol in slice.MarginInterestRates: interest_rate = slice.MarginInterestRates[self.symbol].InterestRate self.Log(f"{self.symbol} close at {slice.Time}: {interest_rate}")
public override void OnData(Slice slice) { if (slice.MarginInterestRates.ContainsKey(_symbol)) { var interestRate = slice.MarginInterestRates[_symbol].InterestRate; Log($"{_symbol} price at {slice.Time}: {interestRate}"); } }
You can also iterate through all of the data objects in the current Slice.
def OnData(self, slice: Slice) -> None: for symbol, margin_interest_rate in slice.MarginInterestRates.items(): interest_rate = margin_interest_rate.InterestRate self.Log(f"{symbol} close at {slice.Time}: {interest_rate}")
public override void OnData(Slice slice) { foreach (var kvp in slice.MarginInterestRates) { var symbol = kvp.Key; var marginInterestRate = kvp.Value; var interestRate = marginInterestRate.InterestRate; Log($"{symbol} price at {slice.Time}: {interestRate}"); } }
For more information about accessing Crypto Future data, see Handling Data.


Contributing¶
Welcome to NDBC
contributor’s guide.
This document focuses on getting any potential contributor familiarized with the development processes, but other kinds of contributions are also appreciated.
If you are new to using git or have never collaborated in a project previously, please have a look at contribution-guide.org. Other resources are also listed in the excellent guide created by FreeCodeCamp [1].
Please notice, all users and contributors are expected to be open, considerate, reasonable, and respectful. When in doubt, Python Software Foundation’s Code of Conduct is a good reference in terms of behavior guidelines.
Issue Reports¶
If you experience bugs or general issues with NDBC
, please have a look
on the issue tracker. If you don’t see anything useful there, please feel
free to fire an issue report.
Tip
Please don’t forget to include the closed issues in your search. Sometimes a solution was already reported, and the problem is considered solved.
New issue reports should include information about your programming environment (e.g., operating system, Python version) and steps to reproduce the problem. Please try also to simplify the reproduction steps to a very minimal example that still illustrates the problem you are facing. By removing other factors, you help us to identify the root cause of the issue.
Documentation Improvements¶
You can help improve NDBC
docs by making them more readable and coherent, or
by adding missing information and correcting mistakes.
NDBC
documentation uses Sphinx as its main documentation compiler.
This means that the docs are kept in the same repository as the project code, and
that any documentation update is done in the same way was a code contribution.
The docs are currently being maintained using .rst
RestructuredText files.
Tip
Please notice that the GitHub web interface provides a quick way of propose changes in
NDBC
’s files. While this mechanism can be tricky for normal code contributions, it works perfectly fine for contributing to the docs, and can be quite handy.If you are interested in trying this method out, please navigate to the
docs
folder in the source repository, find which file you would like to propose changes and click in the little pencil icon at the top, to open GitHub’s code editor. Once you finish editing the file, please write a message in the form at the bottom of the page describing which changes have you made and what are the motivations behind them and submit your proposal.
When working on documentation changes in your local machine, you can
compile them using tox
:
tox -e docs
and use Python’s built-in web server for a preview in your web browser
(http://localhost:8000
):
python3 -m http.server --directory 'docs/_build/html'
Code Contributions¶
This project is comprised (so far) of a single class DataBuoy
. For this class
there are two main models that describe the data requirements. These are the
DataBuoy
itself and a DataPackage
model, representing a specific data
package provided by the NDBC data stations (e.g. stdmet, cwind, etc.).
Design is currently being revised to follow more common design patterns. Contributors can review the state of this work here
Submit an issue¶
Before you work on any non-trivial code contribution it’s best to first create a report in the issue tracker to start a discussion on the subject. This often provides additional considerations and avoids unnecessary work.
Create an environment¶
Before you start coding, we recommend creating an isolated virtual
environment to avoid any problems with your installed Python packages.
This can easily be done via either virtualenv
:
virtualenv <PATH TO VENV>
source <PATH TO VENV>/bin/activate
or Miniconda:
conda create -n NDBC python=3 six virtualenv pytest pytest-cov
conda activate NDBC
Clone the repository¶
Create an user account on GitHub if you do not already have one.
Fork the project repository: click on the Fork button near the top of the page. This creates a copy of the code under your account on GitHub.
Clone this copy to your local disk:
git clone git@github.com:GenSci/NDBC.git cd NDBC
You should run:
pip install -U pip setuptools -e .
to be able to import the package under development in the Python REPL.
Implement your changes¶
Create a branch to hold your changes:
git checkout -b my-feature
and start making changes. Never work on the main branch!
Start your work on this branch. Don’t forget to add docstrings to new functions, modules and classes, especially if they are part of public APIs.
Add yourself to the list of contributors in
AUTHORS.rst
.When you’re done editing, do:
git add <MODIFIED FILES> git commit
to record your changes in git.
Please make sure to see the validation messages from
pre-commit
and fix any eventual issues. This should automatically use flake8/black to check/fix the code style in a way that is compatible with the project.Important
Don’t forget to add unit tests and documentation in case your contribution adds an additional feature and is not just a bugfix.
Moreover, writing a descriptive commit message is highly recommended. In case of doubt, you can check the commit history with:
git log --graph --decorate --pretty=oneline --abbrev-commit --all
to look for recurring communication patterns.
Please check that your changes don’t break any unit tests with:
tox
(after having installed
tox
withpip install tox
orpipx
).You can also use
tox
to run several other pre-configured tasks in the repository. Trytox -av
to see a list of the available checks.
Submit your contribution¶
If everything works fine, push your local branch to GitHub with:
git push -u origin my-feature
Go to the web page of your fork and click “Create pull request” to send your changes for review.
Troubleshooting¶
The following tips can be used when facing problems to build or test the package:
Make sure to fetch all the tags from the upstream repository. The command
git describe --abbrev=0 --tags
should return the version you are expecting. If you are trying to run CI scripts in a fork repository, make sure to push all the tags. You can also try to remove all the egg files or the complete egg folder, i.e.,.eggs
, as well as the*.egg-info
folders in thesrc
folder or potentially in the root of your project.Sometimes
tox
misses out when new dependencies are added, especially tosetup.cfg
anddocs/requirements.txt
. If you find any problems with missing dependencies when running a command withtox
, try to recreate thetox
environment using the-r
flag. For example, instead of:tox -e docs
Try running:
tox -r -e docs
Make sure to have a reliable
tox
installation that uses the correct Python version (e.g., 3.7+). When in doubt you can run:tox --version # OR which tox
If you have trouble and are seeing weird errors upon running
tox
, you can also try to create a dedicated virtual environment with atox
binary freshly installed. For example:virtualenv .venv source .venv/bin/activate .venv/bin/pip install tox .venv/bin/tox -e all
Pytest can drop you in an interactive session in the case an error occurs. In order to do that you need to pass a
--pdb
option (for example by runningtox -- -k <NAME OF THE FALLING TEST> --pdb
). You can also setup breakpoints manually instead of using the--pdb
option.
Maintainer tasks¶
Releases¶
If you are part of the group of maintainers and have correct user permissions
on PyPI, the following steps can be used to release a new version for
NDBC
:
Make sure all unit tests are successful.
Tag the current commit on the main branch with a release tag, e.g.,
v1.2.3
.Push the new tag to the upstream repository, e.g.,
git push upstream v1.2.3
Clean up the
dist
andbuild
folders withtox -e clean
(orrm -rf dist build
) to avoid confusion with old builds and Sphinx docs.Run
tox -e build
and check that the files indist
have the correct version (no.dirty
or git hash) according to the git tag. Also check the sizes of the distributions, if they are too big (e.g., > 500KB), unwanted clutter may have been accidentally included.Run
tox -e publish -- --repository pypi
and check that everything was uploaded to PyPI correctly.

New Jersey man killed when ATV crashes in Pennsylvania
PENN FOREST, Pa. (AP) - Authorities say a New Jersey man injured in an ATV crash in Pennsylvania has died from his injuries.
The crash in Penn Forest occurred shortly after 8 p.m. Saturday.
Authorities say 40-year-old Jason Borys, of Clifton, was driving the ATV when it veered off the road and crashed. He was pronounced dead a short time later.
The cause of the accident remains under investigation. Authorities say "adverse" weather conditions and alcohol may have played a role in the crash.
No other injuries were reported in the accident.

BULWORTH A film review by Matt Williams
RATING: * * out of * * * *
After a longer than usual absence from the big screen, Warren Beatty has returned in a chancy political comedy. And while it's not bad when he's aiming for laughs, the movie switches gears halfway through, attempting to be an earnest political drama...a move that just doesn't fly.
California Senator Jay Billingston Bulworth (Warren Beatty) is suffering a nervous breakdown during the last weekend before the Democratic primary. He has lost the idealism of his youth, and is jaded by the flood of politically correct sound bytes which monopolize his life. His depression gets deep enough that he hires a hitman to assassinate him before the primary.
His final weekend is a liberating one for him. No future means no political repercussions, and Senator Bulworth decides to finally speak his mind. No topic is safe as he bluntly expresses his filter-free views on race relations, socialism, the entertainment industry, and corporate campaign contributions.
At this point, the movie is on a roll...and at this point, it falters. Rather than sticking with the funny concept of a politician finally speaking his mind, the film gets high minded, and he begins speaking the "truth" (or at least Warren Beatty's version of it).
Until then, the film does have several good barbs, and Beatty gives a mostly amusing performance. This time around, he takes a "warts-and-all" approach to filmmaking (obviously sensitive to the soft lighting criticisms he received for Love Affair). However, he still can't resist placing a romantic angle in this unromantic film. This time around, Halle Berry plays his love interest, a campaign volunteer with an agenda of her own, in a subplot that just doesn't float with the rest of the movie.
Even though the romance doesn't quite fit, Berry does a decent job with her role. As do most of the supporting cast, including talents such as Paul Sorvino, Jack Warden and Isaiah Washington. However, the standout here is Oliver Platt, as Bulworth's frazzled campaign manager, trying to make some sort of sense of his boss' new enlightenment.
For a political comedy to work, it either needs to forswear any political message, or at least make it subservient to the humor. Bulworth doesn't follow this advice (or not for long, anyway), and crashes and burns just when it should be hitting new heights.

How to set up your custom domain?
In order to set up your custom domain you'll need to point its DNS over to us. Look for the DNS options in your registrar's control panel.
If you'd like your main root/apex domain to point to us (such as example.com), you'll have to set two DNS entries for your domain.
| Type |
Host |
Value |
A Record |
@ |
<IP_ADDRESS> |
CNAME Record |
www |
www.gamejolt.io |
If there is a TTL setting, you can leave that as the default for each entry.
This will set up your DNS to redirect your root/apex domain (example.com) over to a www subdomain (www.example.com). This ensures that people hit the correct host when trying to view your custom domain site.
If you'd like to point a subdomain over to us (such as mygame.mystudio.com), you will only have to set one entry for the subdomain portion of your domain.
| Type |
Host |
Value |
CNAME Record |
mygame |
www.gamejolt.io |
Note that it could take up to 24 hours for your domain registrar to propagate these changes across the internet and for your site to be accessible using your custom domain.
If you're having trouble, send an email to<EMAIL_ADDRESS>with all the information you can and we'll help you out!

JS helpers¶
This is a developer description of how the helpers works.
The helpers are “private” functions to split how the component works in a better, modular and cleaner way.
In convention, the helpers start with _
, e.g.: jsConfirm._postForm
.
jsConfirm avoid the use of Closures
for performance reasons, for more, please see: High Performance JavaScript
_click¶
It’s the event attached to the click event
, it’s an unique event that launch the modals, fire the ajax call or the callback
and close the modal (For performance).
| e: | Event |
|---|
_postForm¶
This function makes the ajax call, retry if it fails and call the callback
with the data.
| url: | URL to send the call |
|---|---|
| params: | Data to send |
| callback: | Callback |
| retry: | If it’s true, and it fails, then retry |
_get¶
This is the cache factory, it store the calculated values the first time they are need it, after that it return the precalculated value avoiding to hit the DOM at least you force it.
| name: | Variable name |
|---|---|
| getFn: | Function to calculate |
| force: | Discard cache |
_prepareModal¶
If the modal window don’t exists then it call _createModal
, after that, see if the windows have been resized, if it does then call _recalculate
and at the end call _startPosition
to place the window at the rignt place.
_createModal¶
Create the modal window in a verbose way following ECMAScript standard.
Please notice: ECMAScript way it’s slower than innerHTML in old browsers (1.17x times slower in Firefox 3.5) and faster in new WebKit browsers (1.15x times faster in Chrome 3), it’s the same for Opera 10.
_visible¶
Return true
if the modal window it’s visible without touch the DOM
_resize¶
It’s the event attached to the resize event
, if the modal window is visible then call _recalculate
and _center
to place in the right place inmediatly, if it’s not then set resized
to true
and the recalculation will be executed only when they are need it.
_getChildByClasses¶
Get a child element using more than one classes
| d: | DOM element |
|---|---|
| classNames: | Classes to get |
_windowWidth¶
Get the window width
_windowHeight¶
Get the window height
_center¶
Center the modal in the screen
| d: | Modal window |
|---|---|
| animate: | If it’s false then move the window inmediatly |
_startPosition¶
Move the modal window to his start position
| d: | Modal window |
|---|---|
| animate: | If it’s false then move the window inmediatly |
_show¶
Call _prepareModal
to get all set, set the custom text for the element and show the modal calling _vCenter
, in the process set window
and target
to keep track of what’s happening without hit the DOM.
| d: | Modal caller element |
|---|---|
| className: | Modal caller class |
_hide¶
Hide the modal window, and clear window
and target

Six degrees of separation is the idea that all people are six, or fewer, social connections away from each other. As a result, a chain of "a friend of a friend" statements can be made to connect any two people in a maximum of six steps. It was originally set out by Frigyes Ka...


The comedian Hasan Minhaj, of the former Netflix weekly show Patriot Act, focused a popular episode 1 [9.11.166] of his show on student loans in the US. Amazingly, this led to an invitation to testify before Congress on September 10, 2019, on the student loan debt crisis.

Create a new middleware function to hand off request to
handle
when the incoming host for the request matches
hostname
. The function is called as
handle(req, res, next)
, like a standard middleware.
hostname
can be a string or a RegExp object. When
hostname
is a string it can contain *
to match 1
or more characters in that section of the hostname. When
hostname
is a RegExp, it will be forced to case-insensitive
(since hostnames are) and will be forced to match based on the start and
end of the hostname.
When host is matched and the request is sent down to a vhost handler, the
req.vhost
property will be populated with an object. This
object will have numeric properties corresponding to each wildcard (or
capture group if RegExp object provided) and the
hostname
that was matched.

Ne te quaesiveris extra.
I read the other day some verses written by an eminent painter which were original and not conventional. The soul always hears an admonition in such lines, let the subject be what it may. The sentiment they instill is of more value than any thought they may contain. To believe your own thought, to believe that what is true for you in your private heart is true for all men, — that is genius.
Speak your latent conviction, and it shall be the universal sense; for the inmost in due time becomes the outmost,—- and our first thought is rendered back to us by the trumpets of the Last Judgment. Familiar as the voice of the mind is to each, the highest merit we ascribe to Moses, Plato, and Milton is, that they set at naught books and traditions, and spoke not what men but what they thought. A man should learn to detect and watch that gleam of light which flashes across his mind from within, more than the lustre of the firmament of bards and sages.
“A man should learn to detect and watch that gleam of light which flashes across his mind from within…”
Yet he dismisses without notice his thought, because it is his. In every work of genius we recognize our own rejected thoughts: they come back to us with a certain alienated majesty. Great works of art have no more affecting lesson for us than this. They teach us to abide by our spontaneous impression with good-humored inflexibility then most when the whole cry of voices is on the other side. Else, to-morrow a stranger will say with masterly good sense precisely what we have thought and felt all the time, and we shall be forced to take with shame our own opinion from another.
There is a time in every man’s education when he arrives at the conviction that envy is ignorance; that imitation is suicide; that he must take himself for better, for worse, as his portion; that though the wide universe is full of good, no kernel of nourishing corn can come to him but through his toil bestowed on that plot of ground which is given to him to till. The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried.
Not for nothing one face, one character, one fact, makes much impression on him, and another none. This sculpture in the memory is not without preestablished harmony. The eye was placed where one ray should fall, that it might testify of that particular ray. We but half express ourselves, and are ashamed of that divine idea which each of us represents.
“There is a time in every man’s education when he arrives at the conviction that envy is ignorance; that imitation is suicide; that he must take himself for better, for worse…”
It may be safely trusted as proportionate and of good issues, so it be faithfully imparted, but God will not have his work made manifest by cowards. A man is relieved and gay when he has put his heart into his work and done his best; but what he has said or done otherwise, shall give him no peace. It is a deliverance which does not deliver. In the attempt his genius deserts him; no muse befriends; no invention, no hope.
Trust thyself: every heart vibrates to that iron string. Accept the place the divine providence has found for you, the society of your contemporaries, the connection of events. Great men have always done so, and confided themselves childlike to the genius of their age, betraying their perception that the absolutely trustworthy was seated at their heart, working through their hands, predominating in all their being. And we are now men, and must accept in the highest mind the same transcendent destiny; and not minors and invalids in a protected corner, not cowards fleeing before a revolution, but guides, redeemers, and benefactors, obeying the Almighty effort, and advancing on Chaos and the Dark.

While there are many similarities between JavaScript and Ruby, there are also a many differences. One in particular, is the idea of hashes in Ruby and it's somewhat functionally equivalent JavaScript counterpart, the object literal.
In Ruby, hashes are unstructured arrays. Instead of having a set order of items, hashes organize items using keys as references to the value they hold. For more on this, refer to this post.
Example of a hash in Ruby
While JavaScript also has arrays to store items in an ordered list, it doesn't have hashes with key-value pairs like Ruby. However, it has objects (or object literals) that are functionally, and structurally similar.
Example of an object in JavaScript
The MDN JavaScript Guide defines "an object literal [as] a list of zero or more pairs of property names and associated values of an object, enclosed in curly braces." As such, it is very similar to how hashes function in Ruby and syntactically it even looks similar.
However is is important to note that in Ruby the keys can be any data type: string, symbol, array, another hash, etc. In JavaScript, this isn't so. Strings, numbers, and variables are acceptable properties in a JS object but with regards to using variables, there are some restrictions. Variables must conform to the same requirements as other variables in JavaScript (although properties can still point to any data type value, including functions) and if it isn't a valid variable, it must be used inside quotes.
To access items in a Ruby hash, you would use bracket notation:
ruby_hash[:name]
To access items in a JS object, you can use bracket (with quotes) or dot notation.
js_Object['name']
js_Object.age
Another difference is that JS objects can store functions as property values and it is this ability that allows you to create JS methods (functions associated with a particular object). Whereas Ruby can only take values and variables. It is this characteristic that make JS objects different from hashes but similar to creating a class in Ruby.
In all, Ruby hashes and JavaScript objects are functionally and syntactically similar. The differences lie in the restrictions placed on what makes a key/value in Ruby hashes and those placed on properties/values in JS objects as well as the different ways of accessing the information using bracket and/or dot notation.
