# Django Extension
> New in 2.0.0
Dynaconf extensions for Django works by patching the settings.py file with dynaconf loading hooks, the change is done on a single file and then in your whole project every time you call django.conf.settings you will have access to dynaconf attributes and methods.
Ensure dynaconf is installed on your env pip install dynaconf[yaml]
## Initialize the extension
You can manually append at the bottom of your django project’s settings.py the following code:
`python
# HERE STARTS DYNACONF EXTENSION LOAD (Keep at the very bottom of settings.py)
# Read more at https://dynaconf.readthedocs.io/en/latest/guides/django.html
import dynaconf # noqa
settings = dynaconf.DjangoDynaconf(__name__) # noqa
# HERE ENDS DYNACONF EXTENSION LOAD (No more code below this line)
`
Or optionally you can, on the same directory where your manage.py is located run:
```bash export DJANGO_SETTINGS_MODULE=yourapp.settings $ dynaconf init
# or passing the location of the settings file
$ dynaconf init –django yourapp/settings.py
Dynaconf will append its extension loading code to the bottom of your yourapp/settings.py file and will create settings.toml and .secrets.toml in the current folder (the same where manage.py is located).
> TIP Take a look at [example/django_example](https://github.com/rochacbruno/dynaconf/tree/master/example/django_example)
## Using DJANGO_ environment variables
Then django.conf.settings will work as a dynaconf.settings instance and DJANGO_ will be the global prefix to export environment variables.
Example:
`bash
export DJANGO_DEBUG=true # django.conf.settings.DEBUG
export DJANGO_INTVALUE=1 # django.conf.settings['INTVALUE']
export DJANGO_HELLO="Hello" # django.conf.settings.get('HELLO')
`
> TIP: If you dont want to use DJANGO_ as prefix for envvars you can customize by passing a new name e.g: dynaconf.DjangoDynaconf(__name__, ENVVAR_PREFIX_FOR_DYNACONF=”FOO”) then export FOO_DEBUG=true
You can also set nested dictionary values, for example lets say you have a configuration like this:
settings.py
- ‘default’: {
‘NAME’: ‘db’, ‘ENGINE’: ‘module.foo.engine’, ‘ARGS’: {‘timeout’: 30}
}
}¶
And now you want to change the values of ENGINE to other.module, via environment variables you can use the format ${ENVVAR_PREFIX}_${VARIABLE}__${NESTED_ITEM}__${NESTED_ITEM}
Each __ (dunder, a.k.a double underline) denotes access to nested elements in a dictionary.
So:
`bash
export DYNACONF_DATABASES__default__ENGINE=other.module
`
will result in
- ‘default’: {
‘NAME’: ‘db’, ‘ENGINE’: ‘other.module’, ‘ARGS’: {‘timeout’: 30}
}
}¶
Read more on [environment variables](https://dynaconf.readthedocs.io/en/latest/guides/environment_variables.html#nested-keys-in-dictionaries-via-environment-variables)
## Settings files
You can also have settings files for your Django app, in the root directory (the same where manage.py is located) put your settings.{yaml, toml, ini, json, py} and .secrets.{yaml, toml, ini, json, py} files and then define your environments [default], [development] and [production].
> NOTE: .yaml is the recommended format for Django applications because it allows complex data structures in easy way, but feel free to choose any format you are familiar with.
To switch the working environment the DJANGO_ENV variable can be used, so DJANGO_ENV=development to work in development mode or DJANGO_ENV=production to switch to production.
> IMPORTANT: To use $ dynaconf CLI the DJANGO_SETTINGS_MODULE environment variable must be defined.
IF you don’t want to manually create your config files take a look at the [CLI](cli.html)
## Customizations
It is possible to customize how your django project will load settings, example: You want your users to customize a settings file defined in export PROJECTNAME_SETTINGS=/path/to/settings.toml and you want environment variables to be loaded from PROJECTNAME_VARNAME
Edit django settings.py and modify the dynaconf extension part:
from:
`python
# HERE STARTS DYNACONF EXTENSION LOAD
...
settings = dynaconf.DjangoDynaconf(__name__)
# HERE ENDS DYNACONF EXTENSION LOAD
`
to:
```python # HERE STARTS DYNACONF EXTENSION LOAD … settings = dynaconf.DjangoDynaconf(
__name__, ENVVAR_PREFIX_FOR_DYNACONF=’PROJECTNAME’, ENV_SWITCHER_FOR_DYNACONF=’PROJECTNAME_ENV’, SETTINGS_FILE_FOR_DYNACONF=’/etc/projectname/settings.toml’, ENVVAR_FOR_DYNACONF=’PROJECTNAME_SETTINGS’, INCLUDES_FOR_DYNACONF=[‘/etc/projectname/plugins/*’],
) # HERE ENDS DYNACONF EXTENSION LOAD ```
Variables on environment can be set/override using PROJECTNAME_ prefix e.g: export PROJECTNAME_DEBUG=true.
Working environment can now be switched using export PROJECTNAME_ENV=production it defaults to development.
Your settings are now read from /etc/projectname/settings.toml (dynaconf will not perform search for all the settings formats). This settings location can be changed via envvar using export PROJECTNAME_SETTINGS=/other/path/to/settings.py{yaml,toml,json,ini}
You can have additional settings read from /etc/projectname/plugins/* any supoprted file from this folder will be loaded.
You can set more options, take a look on [configuration](configuration.html)
## Reading Settings on Standalone Scripts
> NOTE: The recommended way to create standalone scripts is by creating management commands inside your Django applications or pugins.
> IMPORTANT If you need that script to be out of your Django Application Scope, it is also possible and if needed you can use settings.DYNACONF.configure() instead of the common settings.configure() provided by Django.
### Examples:
Examples below assumes you have DJANGO_SETTINGS_MODULE environment variable set, either by exporting it to your env or by explicitly adding it to os.environ dictionary.
> IMPORTANT: If you call settings.configure() directly dynaconf will be disabled. As you have DJANGO_SETTINGS_MODULE exported you don’t need to call it, but if you need please use: settings.DYNACONF.configure().
#### Common case
/etc/my_script.py
`python
from django.conf import settings
print(settings.DATABASES)
`
#### Explicitly adding the setting module
/etc/my_script.py ```python import os os.environ[‘DJANGO_SETTINGS_MODULE’] = ‘foo.settings’
from django.conf import settings print(settings.DATABASES) ```
#### When you need the configure
> Calling DYNACONF.configure() is needed when you want to access dynaconf special methods like using_env, get, get_fresh etc…
/etc/my_script.py
`python
from django.conf import settings
settings.DYNACONF.configure()
print(settings.get('DATABASES'))
`
#### Importing settings directly (recommended for the above case)
/etc/my_script.py
`python
from foo.settings import settings
print(settings.get('DATABASES'))
`
#### Importing settings via importlib
/etc/my_script.py
`python
import os
import importlib
settings = importlib.import_module(os.environ['DJANGO_SETTINGS_MODULE'])
print(settings.get('DATABASES'))
`
## Testing on Django
Django testing must work out of the box!
But in some cases when you mock stuff and need to add environment variables to os.environ on demand for test cases it may be needed to reload the dynaconf.
To do that write up on your test case setup part:
```py import os import importlib from myapp import settings # NOTE: this uses your app module not django.conf
- class TestCase(…):
- def setUp(self):
os.environ[‘DJANGO_FOO’] = ‘BAR’ # dynaconf should read it and set settings.FOO importlib.reload(settings)
- def test_foo(self):
self.assertEqual(settings.FOO, ‘BAR’)
## Explicit mode
Some users have the preference to explicitly load each setting variable inside the settings.py and then let django manage it in the common way, it is possible.
> NOTE Doing this way misses the ability to use dynaconf methods like using_env, get etc on your django applications code, you can use it only inside settings.py
Dynaconf will be available only on settings.py scope, on the rest of your application settings is managed by Django normally.
settings.py ```py import sys from dynaconf import LazySettings
settings = LazySettings(**YOUR_OPTIONS_HERE)
DEBUG = settings.get(‘DEBUG’, False) DATABASES = settings.get(‘DATABASES’, {
- ‘default’: {
‘ENGINE’: ‘…’, ‘NAME’: ‘…
}
})¶
# At the end of your settings.py settings.populate_obj(sys.modules[__name__], ignore=locals()) ```
> NOTE: Starting in 2.1.1 the ignore argument will tell Dynaconf to not override variables that already exists in the current settings file, remove it if you want all the existing local variables to be overwritten by dynaconf.
You can still change env with export DJANGO_ENV=production and also can export variables lile export DJANGO_DEBUG=true
## Knowm Caveats
If settings.configure() is called directly it disables Dynaconf, use settings.DYNACONF.configure()
## Deprecation note
On old dynaconf releases the solution was to add dynaconf.contrib.django_dynaconf to INSTALLED_APPS as the first item, this still works but has some limitations so it is not recommended anymore.


Creating components with Stencil
Stencil is a compiler for web components. It allows developers to create custom elements for their website while also allowing the use of common developer tools such as JSX and TypeScript.
Stencil provides a great command-line tool to get started. Build out a
project by running npm init stencil
on the command line and
following the on-screen prompts to create a custom element.
This stamps out a development environment and an example element that we can update as needed.
The @Component
decorator denotes this class as a component.
It requires a tag name (in this case my-component
) but can
take many more configuration options.
Each prop is denoted by the @Prop
decorator. These are
values that can be changed externally through the component's
attributes.
The render()
method describes what the component should
display. This is written in JSX and can contain anything required -
HTML, JS or even other Stencil components.
Each component can have some styles associated with it. These are
applied to the component based on the path suppplied to the
styleUrl
property in the component set up.
The styles applied here are scoped only to that component. This means they can be as generic as possible without having to worry about the contents spilling out and affecting the rest of the page.
The result is a component that can be used like any other element. Stencil provides an index page to demo a component to try it out.
When built, Stencil generates a file that can be dropped in to any project and use the component without having to worry about its inner workings. This includes other Stencil projects, regular HTML pages and also other JavaScript frameworks such as React, Vue and Angular.

What is this?
Back in the days everybody had paper calendars. Now they are back - In a sexy foldable format, for free and in various languages. A paper calendar is simplistic, minimalistic and fits in your pocket. Simplicity counts. Back to the roots with a subtle design. Some call it classic, some call it vintage, but it is definetly avant-garde.
Example
Download the PDF
Just give us some hints how you like your calendar. If you press download, our servers will generate the PDF especially for you. Because we care.
Printing
Most of us have a from the shelf A4 printer at home, those printers are not able to print on the whole sheet of paper. They most often leave out a margin of 5mm and maybe even more on all four sides. Therefore you can change the margin of the calendar in the form above to adapt to your printer. Also make sure you disable scaling and fitting options in the print menu! PROTIP: Use a more expensive printer at your school/university or at work.
Feedback
Every feedback is appreciated! We really like to give you the best calendar experience. Maybe you have an idea to improve the layout or like to work with us?
About
My name is Jendrik, in my spare time I like to code social mini projects. see my website. My brother Philip wrote a Python tool called papr. The script output is a PDF file, a calendar for the next two months - foldable, so it will fit in your pocket. It is dead simple, but extremly cool. Unfortunately, most of the people do not know how to use a Python terminal tool, so I set up this micro site.
This project is based on papr, Python, Cairo, Pango, Flask and runs on an Ubuntu Server.

NB! the content is copied from the [Revizor](https://github.com/w32blaster/revizor/wiki/Smart-commits) wiki for demonstration purposes.
Revizor supports quite common technology, like "Smart Commits", also used in other tools dealing with CVS.
 When Revizor detects these commands, it automatically perfors some actions (like create new review).
The main command is create new review. It looks like:
+review email1 email2 #key1 #key2
where
| Argument | Description |
|---|---|
+revizor |
mandatory tocken. Asks Revizor to create a new review |
email1 email2 |
(optional) list of emails separated by blank spaces or comma. Assignees in Revizor. New review will be assigned to the given users and they will receive an email notifications. If these emails are not existing in Revizor database, then the they will be ignored. |
#key1 #key2 |
(optional) if some issue trackers are set for Revizor, then current review will be associated with the given issue(s). Please check Issue Tracker support page for details. |
When Revizor detects this command, it creates new review with current revision:
+review<EMAIL_ADDRESS><EMAIL_ADDRESS>#ISSUE-KEY-01 #ISSUE-KEY-02
The author will be the CVS committer, header and message will be extracted from the commit message. Each user in Revizor can have any number of aliaces: alternative emails that could be associated with this user.
For example, a developer with email<EMAIL_ADDRESS>can commit the changeset to the Git/Mercurial and leave this message (regarding common rules for commit messages):
"Fix the broken layout
Within this commit I repaired the broken layout on the
user settings page.
+review<EMAIL_ADDRESS><EMAIL_ADDRESS>#KEY-1"
When Revizor pulls this commit, it automatically will create an review with these details:
| Field | Value |
|---|---|
| header | "Fix the broken layout" |
| description | "Within this commit I repaired the broken layout on the user settings page." |
| author |<EMAIL_ADDRESS>(**if this user does not exist in the Revizor system or no one user has this alias, then the upcoming review will be ignored!**) |
| reviewers |<EMAIL_ADDRESS>and<EMAIL_ADDRESS>If these users do not exist in the Revizor, then a review will be created without reviewers |
| issue ticket | let's assume, there is at least one issue tracker in Revizor, having the pattern KEY-\d+ . Then the current review will be associated with the issue having ID KEY-1. |
Please, check the page Issue Tracker support for details.

India vs Bangladesh 2019: Sunil Gavaskar believes stats for day-night Tests should be recorded separately
by Renin Wilben AlbertFormer Indian opener Sunil Gavaskar is of the view that statistics and records of day-night Tests should be maintained independently and not clubbed with the numbers of regular Test matches.
Gavaskar made this suggestion during the build-up to India’s first-ever day-night Test, set to be played at Eden Gardens in Kolkata from November 22.
"The thing I feel is that the stats for pink-ball Test cricket should be separately maintained from red-ball cricket."
Gavaskar went on to add that there should be some sort of distinction between red-ball and white-ball cricket when it comes to the limited-overs formats as well.
"Similarly, for limited-overs cricket also the stats should be separate for red-ball and white-ball, or some sort of distinction made so that future generations can know what was what."
Gavaskar, who was the first batsman to breach the 10,000-run mark in Test cricket, expressed confidence in the notion that pink-ball cricket is here to stay.
"When day-night cricket started not many thought it would be successful but look at the huge following it has now, so there's no reason to believe that day-night Test cricket won't be successful too."
Gavaskar also showered praise on Team India and explained that their lack of experience playing with the pink ball will not be an impediment to their chances in the Kolkata Test.
The Little Master along with Kapil Dev, Sachin Tendulkar, Rahul Dravid, VVS Laxman, and Anil Kumble will be present to witness history being created at Eden Gardens.
India are 1-0 in up the two-match Test series, having gotten the better of Bangladesh by an innings and 130 runs in the first Test at Indore.


Blocked
Simple Problem
- A very simple problem while I was doing a question in a tutorial was that I had forgotten to put a " at the end of a sentence, before the ). This somehow stopped everything from working.
- I compared the code to a similar previous exercise and finally saw the problem.
- I felt puzzled as I was sure my code was correct.
- I learned that tiny syntax errors can cause big problems.
Elegantly Solved
As far as I'm aware, I've yet to solve a problem in an elegant way. I'll be sure to update this blog when I am able.
Confidence in Problem Solving Techniques
- Pseudocode
- Trying something
- Rubber ducky method
- Reading error messages
- Console.logging
- Googling
- Asking your peers for help
- Asking coaches for help
- Improving your process with reflection
I want to become more adept. At the moment I am having a little trouble thinking like a computer.
This is no problem. Though trying things that continuously don't work can be demoralizing.
Talking through the problem with a non-responsive duck is not very helpful at the moment but I'm sure it will become more so when I have more knowledge for the duck to impart back to me.
They are quite often vague.
This is very helpful to find out if the function is working properly but I definitely need more practice.
My old dear friend.
Yes, I am mostly fine with this but I don't want to take up too much of their time as I know they have a lot on their plate also.
Asking for help when it is a small problem is easy. Asking for help when the problem is the whole assignment is not so easy.
Hmmmm, not sure on this one. I guess, at the moment, I'm just muddling through and using whatever I can. I can see how this would be useful though.
Non-tech Explanations of Functions
.map() takes the items in a list(Array) in the order that they appear. It does an already specified change to them and then gives you back the changed list under the new name that we gave it. The list that we started with is not changed.
.filter() is for when we have a list(Array) but we only want the items in the list that match the need. We give the new list a name and if the item that we want passes the test then it appears on the new list.
.reduce() takes all the numbers in a list and makes them equal a single number.

A Night At The Roxbury (1998) * A movie review by Serdar Yegulalp Copyright by Serdar Yegulalp
Look no further than A NIGHT AT THE ROXBURY for evidence of the decline of two institutions: "Saturdy Night Live", which hasn't managed to be funny in over a decade and a half, and American comedies in general. ROXBURY is so wan, so thin and juiceless, that it barely classifies as a movie. It also commits the cardinal comic sin: it's not funny.
ROXBURY gives us the Butabi brothers, Steve and Doug (Will Ferrell and Chris Kattan), who are in themselves clones of an earlier SNL routine, the "Wild and Crazy Guys". The post-high-school Butabis are still stuck in their parents' house, work for dad's flower shop, and head out when the sun goes down in futile attempts to get into upscale nightclubs and score with the ladies. After countless rejections (in a movie like this, anything that happens so much as twice feels "countless"), they get lucky and wind up weaselling their way into the ultrahip Roxbury as part of the entourage of a TV star (Richard Grieco). All along the way we get a barrage of hit-and-miss gags -- the best of which have already been played to death in the trailer.
It's a little distressing how the movie manages to play host to many different pieces of action without making any of them funny, or even interesting. F'rinstance, Father Butabi (Dan Hedaya, they guy who looks like Harry Dean Stanton's weaselly brother) and Mom (Loni Anderson, of all people), are barely milked for a single joke. Their function is to stand there and look bewildered.  What fun is that?
Lacking a story, or even a real moment of comic invention, the ROXBURY creators threw everything else they could think of at the screen, and hoped some of it would stick. Fights, weddings, Wayne-and-Garth antics, and on and on. For some reason I was reminded of the equally lamentable TOMMY BOY, which featured SNL alumns Chris Farley and David Spade, landlocked in a script that was equally barren of entertainment, and equally overstuffed with things to attract, but not keep, our attention,

Doc-Centric Sales: West Region
Sales in the west were the most successful of the four regions. Some of
Doc-Centric's success can be attributed to our long-standing base of
customers. The sales of the M100-11 model were particularly encouraging.
We anticipate even greater success in the current year.


Getting started
Download
Download Musket IDE for Windows
Nightly builds:
We publish nightly build to the Source forge
Installation
Install all of Musket ML Python packages. Read installation instructions here.
Note: if only Generic pipeline package of Musket ML is installed, you way also consider to Install Segmentation Pipeline, Classification Pipeline and Musket Text.
Unzip and launch executable (ds-ide.exe
for Windows and ds-ide
for MacOS).
Watch this in action
Most of the following contents can be also checked in action in this video.
Setting up a project
Launch File->New...
from the main menu.
Choose Musket->Musket Project
in the New
dialog.
Click Next
, enter new project name and click Please configure an interpreter...
to set up python interpreter.
Try Config first in PATH
option first, if it fail o auto-detect you python, use other options.
Click Finish
and accept opening the new perspective.
This will create the project structure for you, details regarding the structure can be found here.
Getting dataset from Kaggle
Installing kaggle stuff
This should be done only once, first time you are getting something from Kaggle.
Run pip install kaggle
in console.
Log into Kaggle
Click on a profile in the top-right corner and choose My Account
On the account page find Api
section and click Create New API Token
.
This will launch the download of kaggle.json
token file.
Put the file into ~/.kaggle/kaggle.json
or C:\Users\<Windows-username>\.kaggle\kaggle.json
depending on OS.
Note: there are potential troubles of creating C:\Users\<Windows-username>\.kaggle
using windows explorer.
To create this folder from console, run cmd
and launch the following commands:
cd C:\Users\<Windows-username>
, mkdir .kaggle
.
Consult to Kaggle API in case of other troubles.
Downloading the dataset
Back to IDE. Select your new project root in project explorer, right-click and select New->Other
...
Choose Musket->Kaggle Dataset
.
Click Next
and select competition
, enter salt
into a search box and click Search
.
Select tgs-salt-identification-chellenge
and click Finish
.
This will start dataset download, check its progress in console.
Analysing dataset
In project explorer, double-click on the newly downloaded train.csv
Dataset editor displays CSV contents statistics, if the data is recognizable.
Analyzers
combo allows to switch between dataset analysis modes.
In this simple binary segmentation there is an only suitable analyzer, but in other uses cases there are more.
So, the statistics on the screenshot is the output of the analyzer.
Besides that, analyzer also splits and sorts data, and we can see that on data
tab.
Visualizers are used to display that data, in our case, as we got raw images, there is an only visualizer.
Masks are also displayed.
Creating an experiment
Following should be done to make an experiment from the dataset:
Click the Generate
button in the toolbar in the top-right corner of the viewer.
Choose a name like train_ds
and Generate Musket Wrappers
, click Ok
.
Accept to configure an experiment, enter any name like exp01
and click Finish
.
You now have exp01
folder inside experiments
folder and config.yaml
file there.
datasets.py
is also generated inside modules
folder.
Editing an experiment
We've got a default experiment for binary segmentation generated in the previous chapter.
You can always find it in project explorer:
Its contents can be edited by double-clicking on the experiment.
Lets make some minor changes to experiment code.
Change the shape to be well eaten by the network to:
Change shape
instruction for shape: [224,224, 3]
Lets reduce the count of folds from default 5 to 3 to speed things up:
Add folds_count: 3
instruction to the root level.
Add some holdout so we can track the effectiveness of the trained experiment:
Add testSplit: 0.2
instruction to the root level.
And add an instructions to dump validation and holdout predictions to CSV right after the training.
Add dumpPredictionsToCSV: true
instruction to the root level.
Running an experiment
Click on Launch experiment
in the tool bar of the editor.
This should launch an experiment, you can track what's going on in the console.
Checking results and logs
When the experiment is finished, overal statistics should appear in the Results and logs
tab:
It must also generate summary.yaml
file in the experiment folder and metrics*.csv
files in metrics
subfolder.
Check these files, they contain lots of useful statistics.
Logs
tab display logs in graphical form.
Log
combo switches between different logs we got, in our case there is one per fold.
We've got following metrics declared in the experiment YAML code:
metrics: #we would like to track some metrics
- binary_accuracy
- dice
So the Metric
combo lists all of them (for the specific fold) and loss:
Checking predictions
As we dumped our validation and holdout predictions to CSV by adding
dumpPredictionsToCSV: true
instruction to the root level of our YAML,
now we have a bunch of CSV files in the predictions
folder of our experiment.
You can use those files directly, our just click the links that appear on the Results and logs
/Results
tab:
This opens up the viewer with visualizers and analyzers that we already seen, this time for particular prediction.
Statistics tab, as usual, displays some chart.
Check out Analyzers
combo, this time there are more of them.
Data
tab, which grouping is affected by the current analyzer displays samples with mask and prediction.
What is next
Check the videos to find out what else can be done using Musket IDE: tutorials.

Definition of a properties interface for the parameters of a combined configuration builder.
This interface defines a number of properties for adapting the construction of a combined configuration based on a definition configuration. Properties can be set in a fluent style.
Important note: This interface is not intended to be implemented by client code! It defines a set of available properties and may be extended even in minor releases.

initialized using this DefaultParametersManager
instance. This way, meaningful defaults can be set. Note that
calling this method overrides all DefaultParametersHandler
objects previously set by one of the
registerChildDefaultsHandler()
methods! So either use this method if a pre-configured manager object is to be
set or call the registerChildDefaultHandler()
methods with the handlers to be registered (in the latter case,
it is not necessary to set a DefaultParametersManager
explicitly; a default one is created behind the
scenes).manager

C++ has two notions of polymorphism, compile-time and runtime.
Compile-time polymorphism (aka generic programming) is implemented in
terms of templates, and allows the provision of code that can work on
many different types of objects. On the other hand, runtime
polymorphism involves the use of virtual member functions. Whereever generic programming can
solve a task, it is preferred over runtime polymorphism, as virtual
member functions introduce procedure call overhead, and inhibit
optimisation. Furthermore, the use of a copyable, assignable and
serialisable class like shared_ptr
introduces additional overheads.
Nevertheless, there are situations that cannot be solve with
compile-time polymorphism, for example a container containing objects
of varying types. The smart, modern way to do runtime polymorphism is
via a smart pointer, such as shared_ptr
, found in TR1. To use
shared_ptr
in a DCAS fashion, your object heirarchy must
implement the following interface (provided as an abstract base class
PolyBase
), and the PolyPackBase
.
template <class T> struct PolyBase: public PolyBaseMarker { typedef T Type; virtual Type type() const=0; virtual PolyBase* clone() const=0; /// cloneT is more user friendly way of getting clone to return the /// correct type. Returns NULL if \a U is invalid template <class U> U* cloneT() const; virtual ~PolyBase() {} }; template <class T> struct PolyPackBase: virtual public PolyBase<T> { virtual void pack(pack_t&, const string&) const=0; virtual void unpack(unpack_t&, const string&)=0; };
Any type may be acceptable for the type identifier system, but needs
to be orderable if using the Factory
class. Typically, ints, enums or strings are used for
the type class. A nice implementation is to use the typeName function
to return a string representation of the type:
string type() const {return typeName<T>();}
The create()
method is a static factory method that allows you to
create an object of the type specified. This is not part of the
PolyBase
interface, but needs to be provided by the base class
of the object heirarchy. Its signature is
static object* create(const Type&);
The Factory
class may used for this purpose: If the base class
of your class heirarchy is object
, and you are using strings
for your runtime type identifier, then declare a factory object as
Factory<object,string> factory; static object* object::create(const string& n) {return factory.create(n);}
The only other thing required is to register the type heirarchy. This
is most conveniently and safely done at factory construction time, and indeed the
Factory
class requires you provide a custom default
constructor, but type registration can happen at any time via the
Factory::registerType<T>()
method, which registers type
T
. The factory method requires that all objects in teh class
heirarchy are default constructible, but other than that makes no
assumptions other than it must have a type()
method.
To assist in deriving classes from PolyBase
, the Poly
template
is provided.
template <class This, class Base=object> struct Poly;The first template argument
This
is the class you're currently defining,
and Base
is the base class you are deriving from, which may be
object
, or may be another class higher in the
hierarchy. This provides an implementation of the clone method. For
each of the serialisation descriptors, there is a similar template, so
PolyPack
, PolyXML
and
PolyJson
.
template <class T, class Type> struct PolyPack: virtual public PolyPackBase<Type> { void pack(pack_t& x, const string& d) const; void unpack(unpack_t& x, const string& d); };These can be used in a ``mixin'' fashion by means of multiple inheritance, eg.
template <class T> struct Object: public Poly<T,object>, public PolyPack<T,string>, public PolyXML<T,string> { string type() const {return typeName<T>();} };
One thing to be very careful of is your inheritance heirarchy. Multiple inheritance can easily cause a "no unique final overrider", because the implementations of the various virtual function come in from different classes that are mixed in. In the examples directory, are two different solutions to this problem - the first is providing a custom implementation template class, by manually copying the mixin definitions, and the second actually uses the mixin definitions through inheritance, but annotates each class with the base template after the class is defined. The two solutions are shown in UML in figure 1.

Quick start¶
Start an empty underwater environment using either
roslaunch uuv_descriptions empty_underwater_world.launch
or
roslaunch uuv_descriptions ocean_waves.launch
Spawn the remotely operated vehicle RexROV (find the robot description files in uuv_descriptions/models/rexrov) as follows
roslaunch uuv_descriptions upload_rexrov.launch mode:=default x:=0 y:=0 z:=-20 namespace:=rexrov
for which mode stands for the configuration of the vehicle to be used. It is important to create the vehicles under a unique namespace to allow simulation of multiple vehicles in the same scenario.
You can start a velocity controller with a joystick teleoperation node as
roslaunch uuv_control_cascaded_pid joy_velocity.launch uuv_name:=rexrov model_name:=rexrov joy_id:=0
In this case model_name refers to the vehicle model, which can be different from the namespace. It is a necessary parameter to load the correct controller and thruster allocation matrix coefficients. The joystick ID is already set zero as default. To find the correct joystick index, you can install and run jstest-gtk.
Note
The mapping of the joystick teleoperation node is set as default for the XBox 360 controller. Remapping is possible by passing the correct indexes of the desired axes in the launch file located in the uuv_vehicle_teleop.
Note
Sometimes Gazebo takes a while to close. Try
killall -9 gzserver gzclient
in case that happens.
Running the simulation remotely¶
If you are having trouble running your application in multiple computers, you can try adding the hostnames and IP addresses of your machines to the /etc/hosts file of the computer running roscore.

CS230 Team Anonymous Demo
Todo:// This experiment visualizes source repositories using an interactive tree. Each disc represents a file, with a radius proportional to the number of lines of code (loc). All rendering is done client-side, in JavaScript. Try hovering on nodes to see the loc number, clicking on directory nodes to fold them, dragging nodes to rearrange the layout, and changing project to see different tree structures. Built with d3.js. Inspired by Code Swarm and Gource.
Once you have a loc metrics file, paste its content below and click on the convert button. This will update the CodeFlower and the JSON textarea, to let you save data for your own CodeFlowers.

Scala Introduction
A quick overview of Scala
Created by Félix-Étienne Trépanier / @felixtrepanier
This is an introduction presentation.
I will not go in depth and will move quicky.
I want give you a quick overview so you can ask questions.
Stop me anytime, I can elaborate on some features with more examples.
Agenda
Scala Basics
Object-Oriented Language Constructs
Functional Programming Language Constructs
Typesafe Reactive Platform
What Is Scala?
Statically Typed (with type inference)
Compiled to Java bytecode
Java Scala Interoperability
Runs on the JVM!
Object-Oriented
Functional
Rich Type System
Basic Syntax
val value: Int = 9
var variable = 5
variable = variable + 5
val isEven = if (Random.nextInt(10) % 2 == 0) {
true
} else {
false
}
val values = for (i <- 1 to 10) yield i
def f(param: String): Boolean = {
param.startsWith("f")
}
Scala syntax is flexible.
Scalable Language, a few language keywords -> extensions seen as part of the language.
No semi-column, some syntax elements are optional -> shorter code, DSL support
val and var! -> express intent
Type annotation is after the identifier name and optional -> less noisy if obvious, but good practice to specify it
Everything is an expression -> no return, shorter code, fits well with val model
Object-Oriented Constructs
Classes
class Message(source: String, content: String) {
require(!source.isEmpty)
private val isEmpty = source.isEmpty
def this(source: String) {
this(source, "")
}
def send(destination: String): Ack = {
???
}
private def encodeMessage(content: String): Array[Byte] = {
???
}
}
Constructor parameters in the class definition (similar to function arguments).
Constructor's body is the body of the class!
Can create more constructors, but they need to call the primary constructor at the end of the chain.
Similar access modifier that Java (public, protected, private, private[this], private[package]).
Abstract Classes
abstract class Message(protected val source: String,
protected val content: String) {
protected val encodedContent: Array[Byte]
def send(destination: String): Ack
}
Very similar to abstract class in Java.
A class can only extends one abtract class.
Traits
trait Sendable {
def send(): Ack
}
trait Logging {
protected val logger = Logger.getLogger(this.getClass)
protected def info(message: String) = logger.info(message)
}
class SendableMessage(source: String, content: String)
extends AbstractMessage with Sendable with Logging {
def send(): Ack = {
logger.info("sending")
???
}
}
This is powerful stuff!
Can be used to model an interface.
But can have behavior!
Classes can extends many traits.
Objects
object MailSender extends Sender {
def send(message: Message): Ack = {
???

Home for static methods.
Companion Objects
class Hello(helloWhat: String) {
def say(): Unit = println(Hello.HELLO + " " + helloWhat)
}
object Hello {
private val HELLO = "hello"
def helloWorld(): Unit = new Hello("world").say()
}
Companions object share the name of the class (defined in the same file).
Home for static methods, can access private members.
Case Classes
case class User(name: String, age: Int)
Equivalent of beans...but much shorter.
Get getters, (setters), equals, hashcode and extractors for free!
Functional Constructs
Functional Programming...programming with functions as computation units.
Pure function, no side effects.
Immutability.
Stateless.
Great for parallelism, testing and reasoning.
Compose easily and favor declarative style.
Functions!
def isEven(value: Int): boolean = {
(value % 2) == 0
}
val list = List(1,2,3)
list.filter(isEven)
Functions that take functions!
Recursion
@tailrec
def findFirst(predicate: (Int) => Boolean, list: List[Int]): Option[Int] = {
if (list.isEmpty) {
None
} else if (predicate(list.head)) {
Some(list.head)
} else {
findFirst(predicate, list.tail)
}
}
findFirst(isEven, List(3, 5, 7, 9, 2, 4))
Functions that calls itself.
Tailrec to avoid stack overflow.
Can create concise and elegant code.
Currying
def findFirst(predicate: (Int) => Boolean, list: List[Int]): Option[Int]
def isEven(value: Int): boolean
def findFirstEven: (List[Int]) => Option[Int] = findFirst(isEven, _)
findFirstEven(List(3, 5, 7, 8, 0))
Function factories :)
Creates a new function where some of the arguments are bound to specific values.
Pattern Matching
@tailrec
def findFirst(predicate: (Int) => Boolean, list: List[Int]): Option[Int] = {
list match {
case Nil => None
case head :: _ if predicate(head) => Some(head)
case _ :: tail => findFirst(predicate, tail)
}
}
Much better switch/case.
Can switch on types (no instanceOf).
Can leverage Scala extractors -> example with case class.
Lazyness & Call by name
class Spaceship(name: String) {
lazy val engine = EngineCreator.createEngine()
def fly() {
engine.start()
}
}
def time(block: => Unit): Long = {
val start = System.currentTimeMillis()
block
System.currentTimeMillis() - start
}
println(time({
Thread.sleep(1000)
}))
lazy is thread-safe lazy initialization of values.
call by name, allows to pass arbitrary block of code that may or may not be executed.
Immutable Data Structures
Scala default collections are immutable.
Modifying an immutable collection results in a new collection, this makes the collections thread-safe.
Structural sharing makes it perform well.
Typesafe Reactive Platform

Police treating London Bridge stabbing as 'terror-related' as man shot by officers
Metropolitan Police have confirmed they are at the scene following the incident and a number of people have been stabbed
by Nicole MorleyA man has been shot by police near London Bridge after several people were stabbed in an incident which is being treated as "terror-related", the Metropolitan Police said.
Footage on social media appeared to show members of the public grappling with the knifeman before being pulled away by armed officers, one of whom shot the suspect at point-blank range.
A bystander appeared to remove a large knife from the scene.
A Scotland Yard statement said: "A number of people have been stabbed."
They added: "However, as a precaution, we are currently responding to this incident as though it is terror-related.
"One man has been shot by police."
No further details about casualties were available, although the London Ambulance Service declared it a major incident.
Witnesses described a scene of panic around London Bridge, moments after the incident.
A man has been detained, the Metropolitan Police said.
The Metropolitan Police said in a statement: "Police were called at 1:58pm to a stabbing at premises near to London Bridge.
"Emergency services attended, including officers from the Met and the City of London Police.
"A man has been detained by police.
"We believe a number of people have been injured."
BBC journalist John McManus said a group of men were involved in a fight on the bridge, police arrived and then he claims shots were fired.
"Police then quickly arrived, including armed police, and then a number of shots were fired at this man," Mr McManus told BBC News.
"Police have now cleared the bridge, everybody has been told to move back and now on the northern side of the bridge, but there are more shots going on.
"I can't see what's happening now because we've been moved out of the way but there are shots going on, and you probably hear the police sounds as well.
"Everybody has cleared the area, the entire bridge has been moved, and right on the northern part of the bridge, right up until quite near the Bank of England, is being cleared."
Prime Minister Boris Johnson said: "I'm being kept updated on the incident at London Bridge and want to thank the police and all emergency services for their immediate response."
Home Secretary Priti Patel wrote on Twitter: "Very concerned by ongoing incident at London Bridge. My thoughts are with all affected. I am grateful for the rapid response of our police and I urge everyone to follow their advice."
Various social media users have reported hearing gunshots from London Bridge.
One video shows what appears to be police pulling equipment out of a vehicle nearby.
Those in the video can be heard saying: "They've actually got guns out. They've got the guns out."
Nurse Jackie Bensfield, 32, described how she asked to be let off a bus on London Bridge after she heard "five or six" gunshots.
Ms Bensfield, who was on her way home from work, said she exited the bus and "ran like hell" to escape the shots.
Connor Allen, who was in his van on the bridge when it was evacuated said: "Everyone just started running, you heard these pops and that was it. We just got out the van and started running."
One business owner told the PA news agency she had been crossing London Bridge to get to her shop on the north side when police officers stopped her.
She said that was when she heard at least five or six gunshots and said that her store has been evacuated.
The woman, who wished to remain anonymous, said: "We heard shooting, it was about five or six shots, I heard five or six quite clearly.
"All my staff have been evacuated."


--- layout: post title: RTX and other stuff date: '2016-02-22' author: Lomeli12 categories: - convention tags: - rtx ---
So, a whole two months into the new year and I haven't put a PROPER update post on here yet. It's about time I fix that.
First thing's first, I will be attending RTX 2016. I had an amazing time last year and hope to have an equally amazing one this year. Looking forward to it.
Second, aside from the spring semester starting about midway last month, I've also started working as a Computer Science (though I've mostly been helping with Math) tutor for my school. As a result, I've had little time to work on mods, and what time I do have, I'm ususally too burnt out to work on stuff. I do try to mod every now and again, but I simply cannot sit down and work. While progress has slowed to almost a halt, you'll still probably see me push stuff every now and again on github. I'll make an update once more time as freed up.
And that should be everything you need to know. Thanks for reading, hope to get something out soon and maybe see some people at RTX.


With the Network of International Women for Brighton and Hove, we are offering free mindfulness training to help improve the wellbeing of women asylum seekers and refugees. If you work with asylum seekers and refugees please help us publicise by displaying this poster and mentioning it to your friends, clients and service users.
If you are interested you can apply here.
What is mindfulness?
Mindfulness can help you find balance through life’s ups and downs. It helps you learn to respond more skilfully when difficulties arise.
Mindfulness training can help you learn to pay attention in the present moment, and therefore spend less time dwelling on the past or worrying about the future. It helps you begin to notice habits of the mind that might not be helpful. The more you can spot these habits and patterns the more you have a choice about how to respond, and find more stability.
How can mindfulness help?
Research has shown that mindfulness can help reduce stress, decrease incidence of depression, improve memory, and strengthen your relationships. It can help to improve sleep, immune function and wellbeing.
However, no approach is right for everyone. So there's an opportunity to try mindfulness and see if it's right for you. To do this you can attend the first few sessions before deciding if you want to continue.
What's involved in mindfulness training?
We offer mindfulness in the form of weekly mindfulness sessions (two hour sessions weekly for ten weeks) for between 12-16 people. There are a limited number of places so you will need to let us know if you are planning to attend. The first four sessions are drop-in, and from then the group is closed to new people. The training is offered in a safe friendly space, by experienced teachers, and free materials and downloadable mindfulness practices will be provided.
When is the next course?
We are running a 10-week course for women asylum seekers and refugees, starting on Tuesday, 9 May 2023, between 10 am and 12 midday. The venue will be a secluded wellbeing garden in Brighton and we will organise transport to help get you there. You can try the first few sessions to see if mindfulness is for you. Please provide your name and contact details (see application above) if you are interested in attending the course.
Transport
We will offer transport or a bus pass to help you get there.
Trauma informed mindfulness training for refugees
We are using a curriculum, Mindfulness Across Borders, that has been produced with refugees and asylum seekers in the UK, so it is sensitive to the experience and traumas you may have faced. The mindfulness teachers leading the course have run it once in Brighton, and have made further adaptations to the curriculum in response to requests from the first group of participants. We can make further adaptations depending on your needs.
Who are we?
We are one of the leading mindfulness centres in the UK. We have taught thousands of people since our first training sessions in 2004.

java.lang.Object net.xylophones.micro.game.mb.Block
public class Block
A class which defines the shapes of each tetrad in each possible rotation and provides methods for determining certain characteristics of each shape.
Each possible tetrad has a constant value
TETRAD_I, TETRAD_J, TETRAD_L
etc.
Each possible tetrad rotation constant value
- one of ROTATION_0, ROTATION_90, ROTATION_180
or ROTATION_270
Combined, a tertad and a rotation have a shape. A shape
is a 4x4 array of booleans, where true
values represent a filled
space and a false
values repeesent a space.
e.g. The J tetrad in the ROTATION_0
position
tfff
tttf
ffff
ffff

It is often useful to update a database by building a new database containing an updated version of the data, and flipping from the old version to the new version, so that newly opened readers start picking up the new version of the database. This can be done to great effect, but there are several things to be aware of if you are performing searches in parallel with this change.
Obviously, deleting the old database and copying or moving a new database into place would leave a window of time in which any readers trying to open the database would find files missing, producing Xapian::DatabaseOpeningError errors. If you simply copy or replace the individual files, you may get even more subtle errors; Xapian will usually notice the discrepancy if some files from an old version of the database and some from a new version are present, but may not always do so, and may well raise Xapian::DatabaseCorruptError if it becomes confused.
There are actually very few filesystem operations which can be used to allow an "atomic" change to be made to a database. Fortunately, there is one such operation: moving a file to a new path, replacing any copies of the database at that path, is an atomic operation on almost all systems. [FIXME - check for details of any systems where it isn't.] All processes will either see the filesystem as it was before the move/replace, or as it was afterwards; there'll never be a partial modification visible.
The recommended approach for flipping database versions is to use a stub database to refer to the current version of the database. One approach is be to append a timestamp to the end of each newly created database, and then to create a stub database file pointing to the latest database. Once the newly created database is in place and ready to be used, the newly created stub database file can be moved to replace the old stub database file, taking advantage of the atomic nature of this operation to ensure that a reader would never see a partially flipped database.
On POSIX filesystems, the contents of an open file can be accessed even if the original file on disk has been unlinked. An open Xapian database maintains an open filehandle to all the files holding the database contents. This allows the old version of the database to be unlinked immediately after the stub database file has been updated, without fear that an open reader will be affected by this deletion.
On non POSIX filesystems (specifically, on Windows), an error will be raised by a reader if the files it was using are deleted before it completes. On such systems, you should either wait for all readers using the old version to close, or be prepared to catch errors due to the deletion.
Don't be tempted to use a symlink instead of a stub database to switch between database versions. Xapian doesn't resolve all symlinks on the path to a database before opening it, so if the symlink is changed while the database is being opened, a mixture of old and new files may be opened.
