--- title: Tutorial: Creating tweetrel keywords: fastai sidebar: home_sidebar summary: "and an overview of its API" description: "and an overview of its API" nb_path: "00_core.ipynb" ---
In order to create this library, we will start out by following the initial steps of the nbdev tutorial to create a basic project structure. We also need to install ghapi, by following the instructions on that link.
Once we have a repo cloned, based on the nbdev_template
template, we run in our terminal:
gh-create-workflow tweet release --contexts secrets
Note that we add --contexts secrets
because we'll need access to the secrets context, which we'll be using to store our Twitter API keys.
The basic workflow skeleton that this creates is:
.github/workflows/tweet-release.yml
.github/scripts/build-tweet-release.py
In order to send tweets, we'll send to use the Twitter API -- we'll use the tweepy
library for this:
import tweepy
You'll need a Twitter API login. If you need to send Tweets on behalf of a different user to the one attached to your login, you'll need to authenticate with Twitter as that user. Run tweetrel-auth
in your terminal and follow the instructions to get those access tokens.
The Twitter part of this tutorial isn't the main thing we want to explain, but the thing to note carefully here is how to access secrets in your workflow.
The Twitter API requires authentication, so we'll store our details in a GitHub secret. We'll just use one secret, we our keys stored space delimited. We generally use an organization secret, so that we can update secrets in one place as needed.
Contexts are passed to ghapi as json-encoded environment variables. Each variable name starts with CONTEXT_
-- so for instance the secrets
context is CONTEXT_SECRETS
. In order to simulate this when testing, ensure that you have set an appropriate environment variable before importing ghapi
. We'll put our JSON encoded secrets for testing into a .secrets
file (which we add to .gitignore
so it won't be pushed to our repo). We put the four parts (consumer_key
, consumer_secret
, access_token
, and access_token_secret
) into a single space delimited secret.
os.environ['CONTEXT_SECRETS'] = Path('.secrets').read_text()
Now we can import ghapi
.
from ghapi.all import *
If you now check the context_secrets
variable, you should find your secrets available as an AttrDict
:
assert 'TWITTER' in context_secrets
Now we'll create a function to unpack our keys, tokens, and secrets for Twitter auth, and login to the API:
def twitter_api():
consumer_key,consumer_secret,access_token,access_token_secret = context_secrets.TWITTER.split()
auth = tweepy.OAuthHandler(consumer_key,consumer_secret)
auth.set_access_token(access_token,access_token_secret)
return tweepy.API(auth)
We can test our login by creating and deleting a tweet:
import time
twapi = twitter_api()
stat = twapi.update_status("Please ignore - testing API")
time.sleep(1)
twapi.destroy_status(stat.id)
We can get a sample release
event payload as follows:
example_rel = example_payload(Event.release)
list(example_rel), example_rel.action
The release
section has the following keys:
', '.join(example_rel.release)
We can create a function that formats a tweet based on this information, which will take the template from an environment variable if available, otherwise will use a reasonable default:
def tweet_text(payload):
if 'workflow' in payload: payload = example_rel
def_tmpl = "New #{repo} release: v{tag_name}. {html_url}\n\n{body}"
tweet_tmpl = os.getenv('TWEETREL_TEMPLATE', def_tmpl)
rel = payload.release
owner,repo = payload.repository.full_name.split('/')
res = tweet_tmpl.format(repo=repo, tag_name=rel.tag_name, html_url=rel.html_url, body=rel.body)
return res if len(res)<=280 else (res[:279] + "…")
...and test it:
print(tweet_text(example_rel))
The sample release payload from GitHub happens to have an empty body
, but other than that, this looks good.
That's all we need to create our function:
def send_tweet():
payload = context_github.event
if 'workflow' in payload: payload = example_payload(Event.release)
if payload.action == 'published': return twitter_api().update_status(tweet_text(payload))
We can pop this into our python script, along with send_tweet()
. Since we're using nbdev, we can enter the following in our terminal to do all that:
nbdev_build_lib
cp tweetrel/core.py .github/scripts/build-tweet-release.py
echo -e "\nsend_tweet()" >> .github/scripts/build-tweet-release.py
After we push to GitHub, we can test it out in the same way we showed in the GitHub Actions tutorial, first by logging in and getting a reference to our workflow:
api = GhApi(owner='fastai', repo='tweetrel', token=github_token())
wf = api.actions.get_workflow('tweet-release.yml')
and then running it:
api.actions.create_workflow_dispatch(wf.id, ref='master')
After you run this, you should find the workflow appears in your "Actions" tab on GitHub, and a tweet will appear in your twitter timeline.
One issue is that currently you'll see three workflows being triggered on the Actions tab in GitHub. That's because the "created" and "released" types are resulting in a trigger, as well as "published". Our function is checking which is being used, and only tweeting for "published", but the runs are still being recorded. This isn't necessarily a big problem, but if you'd like things to be cleaner, you can edit the tweet-release.yml
file to add the following line after the release:
line:
types: [published]
It's also possible to do a more complete end-to-end test by actually making a release, checking that a new run is created, and checking the result of that run:
n_runs = api.actions.list_workflow_runs(wf.id).total_count
try:
rel = api.create_release('test', body='body')
time.sleep(30)
runs = api.actions.list_workflow_runs(wf.id)
test(runs.total_count, n_runs, gt)
test_eq(runs.workflow_runs[0].conclusion, 'success')
finally: api.delete_release(rel)
The above steps are all that's needed to create a Python-based workflow for use in a single project. To make it accessible for any project (including other people's projects), we need to distribute it. The easiest way to do that is with pip
. pip
can install modules directly from GitHub, or from the PyPi repository.
Our first step is to add a command that makes it easy to install the tweetrel
workflow into a project. We can use fastcore.script.call_parse
to create a function that can be run from the terminal.
In the function, we'll use fill_workflow_templates
instead of gh-create-workflow
because it allows us to customize each part of the YAML workflow file exactly as we need it:
@call_parse
def install():
fill_workflow_templates(
name='tweet', event="release:\n types: [published]",
run='pip install -Uq tweetrel',
context=env_contexts('secrets'),
script="import tweetrel\ntweetrel.send_tweet()"
)
In this case, we just used tweetrel
in the "pip install" line, which assumes that the project has been uploaded to pypi (which you can do by typing make release
in your terminal, if you use nbdev or pypi_template. If you are just installing from GitHub directly, you'd use this instead:
run='pip install -Uq git+https://github.com/fastai/tweetrel.git',
Since install
uses call_parse
, we can run it as a standard Python function, so we can test it by executing the function:
install()
Alternatively, we can run it through the CLI, by first adding to our settings.ini
:
console_scripts = tweetrel-install=tweetrel.core:install
...and then installing our library locally:
pip install -e .
...and finaly running the command:
tweetrel-install
If this all works, then you can run make release
to submit your action to pypi and conda, making it available for anyone to use in their workflows.
By following these steps, we have created a Python-based GitHub Action, which can be installed using pip or conda, and can be added to any repo with a single command. See the overview page for this module to see how we document this for end users of the action.

The unix signal is a method of sending messages between processes. When a signal is sent, the operating system interrupts the target process's normal flow of execution. There are standard signals that are used to stop a process, but there are also custom signals that can be used for other purposes. This document is an attempt to list all supported signals that Puma
will respond to. In general, signals need only be sent to the master process of a cluster.
Sending Signals
If you are new to signals, it can be helpful to see how they are used. When a process starts in a *nix-like operating system, it will have a PID - or process identifier that can be used to send signals to the process. For demonstration, we will create an infinitely running process by tailing a file:
$ echo "foo" >> my.log
$ irb
> pid = Process.spawn 'tail -f my.log'
From here, we can see that the tail process is running by using the ps
command:
$ ps aux | grep tail
schneems 87152 0.0 0.0 2432772 492 s032 S+ 12:46PM 0:00.00 tail -f my.log
You can send a signal in Ruby using the Process module:
$ irb
> puts pid
#=> 87152
Process.detach(pid) # https://ruby-doc.org/core-2.1.1/Process.html#method-c-detach
Process.kill("TERM", pid)
Now you will see via ps
that there is no more tail
process. Sometimes when referring to signals, the SIG
prefix will be used. For example, SIGTERM
is equivalent to sending TERM
via Process.kill
.
Puma Signals
Puma cluster responds to these signals:
TTIN
increment the worker count by 1TTOU
decrement the worker count by 1TERM
sendTERM
to worker. The worker will attempt to finish then exit.USR2
restart workers. This also reloads the Puma configuration file, if there is one.USR1
restart workers in phases, a rolling restart. This will not reload the configuration file.HUP
reopen log files defined in stdout_redirect configuration parameter. If there is no stdout_redirect option provided, it will behave likeINT
INT
equivalent of sending Ctrl-C to cluster. Puma will attempt to finish then exit.CHLD
URG
refork workers in phases from worker 0 iffork_workers
option is enabled.INFO
print backtraces of all puma threads

Where I am from
I was born in California and moved up the coast when I was 5. My parents intended to move to Canada but on the way they visited a tiny tourist town called Leavenworth. Leavenworth is a tiny bavarian village located 2-3 hours east of Seattle, nestled in the mountains. I grew up there for most of my formative years before I moved to Seattle after graduation school.
My family
My family consists of my parents and three siblings. My father is deceased but my mother still lives in Leavenworth as well as my brother. My sister lives in Germany. For your information, we don't have a drop fo german in any of us, this is all a coincidence.
What I drink
I enjoy beer and spirits. Beer of choice will always be something hoppy. Typcially I like to drink IPAs but I will occasionally drink ambers and pale ales if they are a bit hoppy. I also enjoy drinking liquor, unmixed. I am not a fan of sweet drinks. My current favorite is gin on the rocks. Hey! No judgement! It's a fast no fuss martini.
What I eat
Favorite foods consists of mexican foods and italian foods. I like noodles a lot! I also enjoy cheese, the creamier the better.


Yes.
The following program copies a source text file to a destination text file. An already existing file with the same name as destination file will be destroyed. The names of the source and destination come from the command line. It looks like this:
java copy sourceFile to destinationFile
Most operating systems come with a user interface that includes a file copy command. The order of the source file and the destination file differs between operating systems. Getting them backwards might be disasterous! Our program requires the word "to" in the command line to ensure that the user knows the correct order.
The program will use a
FileReader
and a
BufferedReader
for input and a
FileWriter
and a
BufferedWriter
for output.


GNOME is a computational platform for generating, studying and analyzing novelty in the context of open-world Artificial Intelligence (AI). Open-world intuitively means that the world is not fully specified, known or parameterized in advance. The real world, as seen from the human perspective, is the best example. In the real world, human beings are constantly having to adapt to novelty, both in the long and short term. In contrast, AI systems are far less versatile, despite having achieved near human-level performance in specific, highly scoped problem areas such as face recognition. As a platform, GNOME allows researchers to simulate and 'play with' novelty as a first-class citizen. GNOME also serves as a testbed for evaluating novelty-adaptive AI agents in strategic gameplaying environments.
GNOME is funded under the DARPA SAIL-ON (Science of Artificial Intelligence and Learning for Open-world Novelty) program. While current AI systems excel at tasks defined by 'rigid' rules, they are not very good at adapting to changing conditions commonly faced by people in the real world: from driving in fluctuating weather, walking on uneven terrain, playing games with slightly different rules (e.g., chess under a time constraint) and, in general, modifying the internal model of the world when an assumption turns out to be faulty.
Currently, GNOME has been implemented for the Monopoly board game, and includes a novelty simulator. The package and simulator is publicly available on GitHub. GNOME is a collaboration with researchers from Purdue University.
This work was funded by the Defense Advanced Research Projects Agency with award W911NF2020003.


15-year-old suspected drug trafficker among 70 arrested in islandwide operation
SINGAPORE: A teenage boy was among 70 suspected drug offenders arrested in an islandwide operation by the Central Narcotics Bureau (CNB) that ended on Friday (Nov 22).
The 15-year-old Singaporean, believed to be a drug trafficker, was being investigated for selling Ice to a 14-year-old Singaporean female suspected drug abuser, CNB said in a news release on Friday.
About 9g of new psychoactive substances, 20g of heroin, 704g of Ice and an Ecstasy tablet was seized during the operation, which began on Monday and covered areas including Bedok, Choa Chu Kang, Tampines, Telok Blangah and Yishun.
There were two "sizeable" Ice seizures during this operation.
During a raid on Wednesday, CNB officers arrested two suspected drug traffickers - a 22-year-old Singaporean female and a 32-year-old Singaporean male - in a residential unit in Yishun Avenue 11.
"A total of about 100g of Ice, an Ecstasy tablet and a small amount of green powdery substances suspected to contain controlled drugs were found within the unit," CNB said.
Other drug paraphernalia like a digital weighing scale and numerous drug-smoking apparatuses were also found within the unit.
Separately, on Thursday evening, CNB officers tailed a 29-year-old Singaporean man when he left a residential block in Yishun Street 81.
His vehicle was later intercepted along Mandai Road and the suspect was arrested. Inside his van, about 580g of Ice, a digital weighing scale and a drug-taking utensil were found.
The 704g of Ice seized during the operation is sufficient to feed the addiction of about 402 abusers for a week, CNB said.
Investigations into the drug activities of all the suspects are ongoing.


China invites US trade negotiators for new round of talks: WSJ
China has invited top U.S. trade negotiators for a new round of face-to-face talks in Beijing amid continued efforts to strike at least a limited deal, the Wall Street Journal reported on Thursday citing unnamed sources.
BEIJING: China has invited top U.S. trade negotiators for a new round of face-to-face talks in Beijing amid continued efforts to strike at least a limited deal, the Wall Street Journal reported on Thursday citing unnamed sources.
The report said Chinese Vice Premier Liu He invited U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin for a meeting in Beijing, adding that Beijing hopes the round of talks can take place before next Thursday's Thanksgiving holiday in the United States.
U.S. officials have indicated they would be willing to meet in person but have not committed to a date, the report said.
However, the negotiators would be reluctant to travel for the talks unless China makes it clear it would make commitments on intellectual property protection, forced technology transfers and agricultural purchases, the report said.

We used the csindexbr score to agregate the data. The histograms
below show the frequencies of csindexbr scores for each CNPq level
(e.g., PQ-1A). The definition of score follows that of csindexbr
(see their FAQ for
details). To sum, papers in venues from tier 1 worth one full
point, papers in tier 2 worth 0.4 point, and papers in tier 3
worth 0.33 point. The score of an individual consists of the sum
of these points since 2013. It is worth noting that (1) only very
few venues fall under tier 1, (2) venues in tier 3 are still
pretty good, and (3) journals and conferences are covered
(although tier 2 is exclusive for journals). Informally, the
selection criteria of csindexbr is more inclusive compared to that
of csrankings, but still very
rigorous.

since it saves you having to iterate over the array more
than once for each frame.
Parameters:
| Name | Type | Description |
|---|---|---|
postUpdate |
function | The function to run after each cell is updated. Should take three params: cellValue, rowIndex, and colIndex. |
- Inherited From:
- Source:
prettyPrint(mapopt) → {string}
Get a nice string representation of the state of the automaton.
Same as module:cellerity.Automaton#prettyPrint, but with
a default map function that works well for lifelike automata.
Parameters:
| Name | Type | Attributes | Description |
|---|---|---|---|
map |
function |
<optional> |
A function to apply to each cell value, returning the string to be used to represent the cell. |
- Overrides:
- Source:
Returns:
A string representation of the automaton's state.
- Type
- string
reset()
Set the automaton's data to initial conditions
- Inherited From:
- Source:
setDimensions(rows, cols)
Change the automaton's dimensions.
This will reset the automaton's state to conform to the chosen
dimensions, using the automaton's current initializer function.
Parameters:
| Name | Type | Description |

setEdgeMode(edgeMode)
Set the automaton's edge behaviour.
If "toroid", the neighbourhood of cells near the edge of the
grid will "wrap around" horizontally and vertically.
If "cylinder", the neighbourhood will wrap horizontally only,
and cells in the top and bottom row will never change.
If "freeze", cells on the edge of the grid will never change.
Parameters:
| Name | Type | Description |
|---|---|---|
edgeMode |
string | The edge mode, one of "toroid", "cylinder", "freeze". |
- Inherited From:
- Source:
setInitializer(initial)
Change the function used to initialize the automaton's state,
and then reset the automaton to the new initial conditions.
If a 2D array is provided, the automaton will be initialized
so as to match the given array as closely as possible, causing
the provided array to repeat in a tiled fashion if it is not
large enough to fully cover the automaton's data grid.
Parameters:
| Name | Type | Description |
|---|---|---|
initial |
initializerFunction | Array.<Array> | Either an initializer function, or a 2D array of cell values, to use to initialize the automaton's state when resetting. |

This is part 3 in a series of posts that looks into DiffUtil on Android. The previous posts in this series are:
- Part 1 where we take a deep dive into the DiffUtil API
- Part 2 where we compare this API with similar APIs on other platforms.
In this post, we’ll look at an example of when to use custom animations.
The sample app
Here’s an example of the animations that we will achieve. The code for this sampe is available here
This is admittedly a goofy example, but it serves a purpose. I originally wanted to demonstrate this using visualization of RingBuffer data structure as an example, but I settled for this Color Circles example because it prevents us from getting distracted learning ring buffer!
Here is how the sample works:
- There are 7 slots, arranged in a circle
- Each slot can be empty, or occupied by a colored view (I chose the colors of the rainbow, hence the number 7)
- Each view can be “expanded” or not
The data for the view is a List<CircleInfo>
where CircleInfo
is defined as follows:
The “Toggle” button switches between two hard-coded lists. It submits the entire list to the ColorCirclesView
, which in turn applies a diff and runs some animations:
- If an item’s
expanded
property changed, then we animate the change in width and height of that view - If an item was removed, then we shrink the view until it disappears, while simultaneously moving it to the center of the circle
- If an item was added, then we expand it from size 0 to its final size, while simultaneously moving it from the center of the circle to its final position along the circumference.
- For items that were present in both lists, but their positions in the list changed, we move the views along the circumference of the circle to arrive at the new positions. This animation “makes room” for items being inserted, and “fills the gap” created by disappearing items.
Finally, we run all these animations in a pre-determined order:
- All removals first
- Then, change animations together with move along circumference animations
- Finally the insertion animations are run
As you might have guessed, this example was carefully chosen to demonstrate the use of custom diffs. This example is not suitable for RecyclerView
- For one, there’s no straightforward way of arranging RV items along a circle
- Even if you do find a circular
LayoutManager
for RV, you are unlikely to get it to work well with RV’sItemAnimator
framework (this framework, although very powerful and flexible, requires you to understand way too much of the RV internal workings) - In this specific example, there’s no recycling happening, so you don’t really need RV. There’s a fixed limit to the number of items (7) and they all fit on screen at once.
Here’s another example with more operations happening: There’s 2 removals, 2 changes and one insertion (I recommend to run the app on an emulator to see the real animations, the fidelity of GIF is not good enough)
Note: There are some situations that this sample does not handle. For example if you submit a list while animations for the previous diff are already in progress, it could crash. However, this is not related to the DiffUtil wrapper that we are discussing in this post, so I’ll leave it as is.
A wrapper for DiffUtil
In the previous posts, we discussed about wrapping Android’s DiffUtil in a collection-style API. It is necessary to do this for our sample. This is because of the order in which we want to run our animations: We want to run all removals together. The standard ListUpdateCallback
has no way of telling us “here are all the items that were removed”.
So, we can start off by doing the obvious: maintain our own list of diff operations (change, remove etc) and keep adding to this list when our ListUpdateCallback
is called. This is implemented here and a snippet is like this
And RawDiffOperation
is defined as
But we can do better. In our sample, we don’t actually care about the exact order in which the diff operations need to be applied. All we care about is the final set of changes, removals and additions. In other words, instead of
Item at index 3 was deleted, then item at index 1 was deleted, then an item was inserted at index 0
we want to say
Items at index 1 and 3 were deleted; and an item was inserted at index 0
AtomicDiffResult
So, we use a combination of the RawDiffOperations and DiffUtil’s position conversion methods (convertNewPositionToOld()
and convertOldPositionToNew()
) to expose an API like this:
Note that this API gives us everything we need to perform our animations. It gives us the item itself in addition to positions. In case of item changes, it gives us both the old and new items. You can see the implementation of AtomicDiffResult here.
Implementation note: This implementation of AtomicDiffResult is leaves some room for optimization since it performs 2 extra iterations over the lists (once over the new list and once over the old one). In this example it is negligible.
Entry point into the API
Now that we know what we want the result to look like, let’s consider how we want to calculate the diff. We want to provide the following pieces of information
- Old list
- New list
- How to compare items in the list
This leads us to the following signature
The implementation of this function is here. You can find the tests for this implementation here.
Wrapping up
In this post, I explored one way to wrap DiffUtil’s ListUpdateCallback
into a more ergonomic API. This is by no means the most generic way:
- It does not handle moves
- It ignores the change payloads
- In some cases you do really want access to the raw diff operations in the order they were performed (note that
AtomicDiffresult
does expose the underlyingList<RawDiffOperation>
for this purpose)
However, it does handle a lot of use cases where you might want to use ListUpdateCallback
. The API style I proposed here is closest to Angular’s style.
The most practical applications of wrapping DiffUtil are in situations where you have lists of data but you don’t want to use RecyclerView to display them. Examples include
- Situations where you have limited number of items and no recycling happening
- Lists shown in bottom sheets
- Custom UI like the one shown in the sample, or visualizing a ring buffer data structure
You might also apply this technique when you want to display custom animations and RV’s ItemAnimator does not suffice for your use case.

Mum promotes inclusivity with picture of son holding 'Men Have Periods Too' sign
Milly Bhaskar, who lives in Hull, posted a picture of her four-year-old son Eli holding the sign. She said 'it's not insulting to women, it's opening up the community to make it a safe space.'
by Lorraine KingA mum's post has gone viral after she shared a photo of her son holding a sign saying "Men Have Periods Too" in order to promote inclusivity.
Milly Bhaskara has amassed thousands of followers on Instagram through her posts that promote self-love, body acceptance and mental health awareness and her latest post features her son Eli.
The sign held up by the four-year-old says: "Some men have periods to. If I can get it so can you."
Milly, who lives in Hull, explains in her caption why she has made the post.
She said: "Some men have periods.. Some non-binary people have periods. Some women have periods.

"I didn’t use the language of women have periods because it’s not entirely inclusive.
"I told him that some women, some non binary people and some men have periods.
"Trans men may have ‘female’ sex organs and still experience periods and some non binary people have periods too therefore removing a female logo off the front of sanitary products helps include us all isn’t that wholesome and a nice gesture?

She turned off the comments section on Instagram but the post has been liked 6,000 times.
However, some people on Facebook didn't agree with her post.
One person wrote: "Wow...wtf! Confuse the kid why don't ya!"
While a third person commented: "Now this is too far lol the world is broken."
Milly's post comes after Always removed the female symbol from its packaging for sanitary products.
It said in a statement: “We’re also committed to diversity and inclusion and are on a continual journey to understand the needs of all of our consumers.”

7.1 Introduction
7.1.1 Table of contents
7.1.2 Objectives
7.1.3 Scope
7.2 Conformance
7.2.1 Conformance of VRML files
7.2.2 Conformance of VRML
generators
7.2.3 Conformance of VRML
browsers
7.3 Minimum support requirements
7.3.1 Minimum support requirements
for generators
7.3.2 Minimum support requirements
for browsers
7.3.3 VRML requirements for
conforming to the base profile
7.3.4 Sound priority, attenuation,
and spatialization
This clause addresses conformance of VRML files, VRML generators and VRML browsers.
The primary objectives of the specifications in this clause are:
Conformance is defined for VRML files and for VRML browsers. For VRML generators, conformance guidelines are presented for enhancing the likelihood of successful interoperability.
A concept of base profile conformance is defined to ensure interoperability of VRML generators and VRML browsers. Base profile conformance is based on a set of limits and minimal requirements. Base profile conformance is intended to provide a functional level of reasonable utility for VRML generators while limiting the complexity and resource requirements of VRML browsers. Base profile conformance may not be adequate for all uses of VRML.
This clause addresses the VRML data stream and implementation requirements. Implementation requirements include the latitude allowed for VRML generators and VRML browsers. This clause does not directly address the environmental, performance, or resource requirements of the generator or browser.
This clause does not define the application requirements or dictate application functional content within a VRML file.
The scope of this clause is limited to rules for the open interchange of VRML content.
A VRML file is syntactically correct according to ISO/IEC 14772 if the following conditions are met:
A VRML file conforms to the base profile if:
A VRML generator is conforming to this part of ISO/IEC 14772 if all VRML files that are generated are syntactically correct.
A VRML generator conforms to the base profile if it can be configured such that all VRML files generated conform to the base profile.
A VRML browser conforms to the base profile if:
There is no minimum complexity which is required of (or appropriate for) VRML generators. Any compliant set of nodes of arbitrary complexity may be generated, as appropriate to represent application content.
This subclause defines the minimum complexity which shall be supported by a VRML browser. Browser implementations may choose to support greater limits but may not reduce the limits described in Table 7.1. When the VRML file contains nodes which exceed the limits implemented by the browser, the results are undefined. Where latitude is specified in Table 7.1 for a particular node, full support is required for other aspects of that node.
In the following table, the first column defines the item for which conformance is being defined. In some cases, general limits are defined but are later overridden in specific cases by more restrictive limits. The second column defines the requirements for a VRML file conforming to the base profile; if a VRML file contains any items that exceed these limits, it may not be possible for a VRML browser conforming to the base profile to successfully parse that VRML file. The third column defines the minimum complexity for a VRML scene that a VRML browser conforming to the base profile shall be able to present to the user. The word "ignore" in the minimum browser support column refers only to the display of the item; in particular, set_ events to ignored exposedFields must still generate corresponding _changed events.

If the browser does not have the resources to play all of the currently active sounds, it is recommended that the browser sort the active sounds into an ordered list using the following sort keys in the order specified:
where priority is the priority field of the Sound node, now represents the current time, startTime is the startTime field of the audio source node specified in the source field, and intensity attenuation refers to the intensity multiplier derived from the linear decibel attenuation ramp between inner and outer ellipsoids.
It is important that sort key 2 be used for the high priority (event and cue) sounds so that new cues will be heard even when the browser is "full" of currently active high priority sounds. Sort key 2 should not be used for normal priority sounds, so selection among them will be based on sort key 3 (intensity at the location of the viewer).
The browser shall play as many sounds from the beginning of this sorted list as it can given available resources and allowable latency between rendering. On most systems, the resources available for MIDI streams are different from those for playing sampled sounds, thus it may be beneficial to maintain a separate list to handle MIDI data.
In order to create a linear decrease in loudness as the viewer moves from the inner to the outer ellipsoid of the sound, the attenuation must be based on a linear decibel ramp. To make the falloff consistent across browsers, the decibel ramp is to vary from 0 dB at the minimum ellipsoid to -20 dB at the outer ellipsoid. Sound nodes with an outer ellipsoid that is ten times larger than the minimum will display the inverse square intensity dropoff that approximates sound attenuation in an anechoic environment.
Browsers may support spatial localization of sounds whose spatialize field is TRUE as well as their underlying sound libraries will allow. Browsers shall at least support stereo panning of non-MIDI sounds based on the angle between the viewer and the source. This angle is obtained by projecting the Sound location (in global space) onto the XZ plane of the viewer. Determine the angle between the Z-axis and the vector from the viewer to the transformed location, and assign a pan value in the range [0.0, 1.0] as depicted in Figure 7.1. Given this pan value, left and right channel levels can be obtained using the following equations:
leftPanFactor = 1 - pan2 rightPanFactor = 1 - (1 - pan)2
Using this technique, the loudness of the sound is modified by the intensity field value, then distance attenuation to obtain the unspatialized audio output. The values in the unspatialized audio output are then scaled by leftPanFactor and rightPanFactor to determine the final left and right output signals. The use of more sophisticated localization techniques is encouraged, but not required (see E.[SNDB]).

Runs a function iteratively over each row of either a dataframe or the results of a query. Use the 'BigQuery' and 'DBI' wrappers to iteratively pass each row of query results to a function. If a field contains a 'JSON' string, it will be converted to an object. This is helpful for queries that return 'JSON' strings that represent objects. These fields can then be treated as objects by the pipeline.

The packet filter plugin allows you to create rules that will block or reject certain packets to the server.  I wasn't happy with some of the design of the 1.0 version so I fixed it. The old format of the rules was unworkable with the new and I couldn't find a good way to convert from the old format, sorry.
By default the packet filter plugin will auto-create rules on Shared Group changes ensuring groups can always communicate with each other.
To disable this behaviour set the following Openfire System Property to false:
Copy packetFilter.jar into the plugins directory of your Openfire installation. The plugin will then be automatically deployed. To upgrade to a new version, copy the new packetFilter.jar file over the existing file.
Currently only the following databases are supported :
The Packet Filter plugin can be configured under "Server"-"Server Settings"-"Packet Filter Rules".
Actions come in 3 types Pass, Drop and Reject.
This allows you to quickly disable a rule without deleting it. Disabled rules will still appear on the main rule page but will have a strike through like so :
This specifies what type of packets you want to disable your choices are :
This specifies the source base JID. Currently resource specific rules aren't supported. The options for specifying a source are :
This specifies the destination base JID. The options for selecting the destination JID are the same as above.
This prints a message to the info.log when the rule is executed. This is recommend only for trouble shooting as it can fill up the logs pretty quickly in production environments. Some example output :
Rejecting packet from<EMAIL_ADDRESS>to<EMAIL_ADDRESS>The first rule that matches an incoming packet will be executed. For example consider the following rules :
Here we don't want any of the Simpson's talking to each other so every message from members of the Simpson group to each other are dropped. However, Marge and Homer should be able to talk to each other. To accomplish this rules allowing Homer to send message packets to Marge and vice versa are placed before the drop rule. New rules are automatically appended to the rule list. Rules can be moved at anytime using the arrows in the UI. When a rule is moved the changes take effect immediately.
