Detailed Description
The QExtensionManager class provides extension management facilities for Qt Designer.
In Qt Designer the extensions are not created until they are required. For that reason, when implementing an extension, you must also create a QExtensionFactory, i.e a class that is able to make an instance of your extension, and register it using Qt Designer's extension manager.
The registration of an extension factory is typically made in the QDesignerCustomWidgetInterface::initialize() function:
void MyPlugin::initialize(QDesignerFormEditorInterface *formEditor) { if (initialized) return; QExtensionManager *manager = formEditor->extensionManager(); Q_ASSERT(manager != 0); manager->registerExtensions(new MyExtensionFactory(manager), Q_TYPEID(QDesignerTaskMenuExtension)); initialized = true; }
The QExtensionManager is not intended to be instantiated directly. You can retrieve an interface to Qt Designer's extension manager using the QDesignerFormEditorInterface::extensionManager() function. A pointer to Qt Designer's current QDesignerFormEditorInterface object (formEditor
in the example above) is provided by the QDesignerCustomWidgetInterface::initialize() function's parameter. When implementing a custom widget plugin, you must subclass the QDesignerCustomWidgetInterface to expose your plugin to Qt Designer.
Then, when an extension is required, Qt Designer's extension manager will run through all its registered factories calling QExtensionFactory::createExtension() for each until the first one that is able to create the requested extension for the selected object, is found. This factory will then make an instance of the extension.
There are four available types of extensions in Qt Designer: QDesignerContainerExtension , QDesignerMemberSheetExtension, QDesignerPropertySheetExtension and QDesignerTaskMenuExtension. Qt Designer's behavior is the same whether the requested extension is associated with a container, a member sheet, a property sheet or a task menu.
For a complete example using the QExtensionManager class, see the Task Menu Extension example. The example shows how to create a custom widget plugin for Qt Designer, and how to to use the QDesignerTaskMenuExtension class to add custom items to Qt Designer's task menu.

Member Function Documentation
QExtensionManager::QExtensionManager(QObject *parent = Q_NULLPTR)
Constructs an extension manager with the given parent.
QExtensionManager::~QExtensionManager()
Destroys the extension manager
[virtual]
QObject *QExtensionManager::extension(QObject *object, const QString &iid) const
Reimplemented from QAbstractExtensionManager::extension().
Returns the extension specified by iid, for the given object.
[virtual]
void QExtensionManager::registerExtensions(QAbstractExtensionFactory *factory, const QString &iid = QString())
Reimplemented from QAbstractExtensionManager::registerExtensions().
Register the extension specified by the given factory and extension identifier iid.
[virtual]
void QExtensionManager::unregisterExtensions(QAbstractExtensionFactory *factory, const QString &iid = QString())
Reimplemented from QAbstractExtensionManager::unregisterExtensions().

Related Non-Members
T qt_extension(QAbstractExtensionManager *manager, QObject *object)
Returns the extension of the given object cast to type T if the object is of type T (or of a subclass); otherwise returns 0. The extension is retrieved using the given extension manager.
QDesignerPropertySheetExtension *propertySheet; QExtensionManager manager = formEditor->extensionManager(); propertySheet = qt_extension<QDesignerPropertySheetExtension*>(manager, widget); if(propertySheet) {...}
When implementing a custom widget plugin, a pointer to Qt Designer's current QDesignerFormEditorInterface object (formEditor
) is provided by the QDesignerCustomWidgetInterface::initialize() function's parameter.
If the widget in the example above doesn't have a defined QDesignerPropertySheetExtension, propertySheet
will be a null pointer.
Macro Documentation
Q_DECLARE_EXTENSION_INTERFACE(ExtensionName, Identifier)
Associates the given Identifier (a string literal) to the extension class called ExtensionName. The Identifier must be unique. For example:
Q_DECLARE_EXTENSION_INTERFACE(MyExtension, "com.mycompany.myproduct.myextension")
Using the company and product names is a good way to ensure uniqueness of the identifier.
When implementing a custom extension class, you must use Q_DECLARE_EXTENSION_INTERFACE() to enable usage of the qt_extension() function. The macro is normally located right after the class definition for ExtensionName, in the associated header file.
See also Q_DECLARE_INTERFACE().


I'm A Celebrity's Dec Donnelly drops huge hint about final leaving fans in panic
The I'm A Celebrity 2019 final date has not yet been announced, but host Dec Donnelly teased when the latest series will end
by Charlotte TuttonI'm A Celebrity fans were a little panicked when Dec Donnelly hinted at the 2019 final date, when the latest series will end.
Dec and co-host Ant McPartlin dropped news about how long the series was on for on ITV, with it launching last Sunday.
Almost all the stars have entered the jungle including Caitlyn Jenner, Jacqueline Jossa, Ian Wright, Roman Kemp and Kate Garraway.
There's two new arrivals set to enter the camp, with reports that Coronation Street's Andy Whyment and former EastEnders star Cliff Parisi are the mystery stars.
Now, Dec has let slip to fans how long they can expect to see their jungle favourites on screen.
While there's plenty of time left on the show, fans already don't want it to end with many tipping it to "fly by".
Dec said to pal Ant that there was still 20 days to go on the show.
With Australia between 8-10 hours ahead of UK time, It's not clear whether they meant 20 days from Monday or Tuesday.
Either way this is the usual amount of time for the ITV jungle series, which last year ended on Sunday 9 December.
This time around, judging by Dec's confession, it's likely to finish on Sunday 8th December.
Taking to Twitter , viewers confessed they weren't quite ready for it to finish even with weeks until then.
One fan said: "20 days to go, it’ll fly by," alongside a crying face emoji.
Another tweeted: "Dec saying 20 days left think I just nearly threw up."
A third added: "20 days left omg."
Meanwhile others were fully aware that was a long amount of time, with one fan commenting: "It’s day 2 Dec..."
I'm A Celebrity continues at 9pm on ITV.

Flexible Feedback was created as a winter break project by middle school teacher Christine Witcher. There are small operating costs associated with running and developing this site. Your donations are appreciated!
Narrative feedback is incredibly important in the classroom. Research tells us that grades without feedback have very limited worth, but we also know that substantial feedback takes hours to write. Flexible Feedback is a web-based tool that makes feedback writing more efficient.
Flexible Feedback is a "client-side" application. This means that there is no database and nothing you enter into the screen is passed through the internet. It's sort of like opening a program on your computer, but the program opens in your browser. In summary, student data stays on your computer and doesn't go anywhere else, nor can we see what you enter.


Notes
- There are two bugs in this application
- The "Clear" button should empty the name and owner field and set the city to "Los Angeles" You will notice it currently clears out all fields and flashes depending on the browser. This isn't necessarily a bug in the javascript.
- After 10 minutes, the authentication for this application will timeout and if the user saves, they should be shown a yellow toastr message. Currently, they are shown an incorrectly colored toastr message.

Working with Voting: {{surveypanel.msg}}
The Survey and Online Voting features both allow you to design electronic surveys or opinion polls. This is a good way to determine how your site visitors feel about things, or even to perform committee or board elections. We suggest that you design your survey on paper before you begin the electronic design. That will help you determine the most effective sequence of questions and the informational text you will want to include to make taking the survey understandable to your visitor.
Like other Features, you can create a button or embedded link that goes to the Feature itself, which will display a list of all available surveys, or one that goes directly to a specific survey.
Select the “Features” button from the Admin Panel and then locate the Survey or Online Voting feature. If you select “Edit,” you will see a screen similar to the one below.
Site Title - If you prefer to name the feature something other than “Survey” or "Online Voting" you can change the name here.
Feature Admin - Selecting a feature administrator from the drop list of your available feature administrators allows you to share the survey/vote creation and monitoring duties with someone else. Use the drop-down menu to display a the list of feature administrators (set in the Users tab on your admin panel)
Require User Authentication - Setting this option to "yes" requires site visitors to log in before accessing the survey/online vote.
Vote by Secret Ballot? - In the online voting feature only, you have the option to disable the secret ballot option. This would allow a site administrator to view how each user has voted on a vote (instead of the default method, where you can view the results only). If you want to disable this, be sure to do it before you create the vote.
When you select “Manage” from the feature screen next to the “Surveys” or "Online Voting" feature, you will see a screen similar to the one below.
To create a new survey/ballot select the “Create New Survey/Ballot” link and a screen like the one shown below will be displayed.
Title - Enter a short title for the survey, like “New Playground.”
Description - Enter a general description of the survey/ballot, what you are trying to accomplish with the survey, and any instructions you want your visitors to follow. The description area is a text area and all the formatting features are available.
Response Period – Select the beginning and ending date for your survey/ballot by either entering a date or clicking on the calendar icon and selection a date.
Display – Set this to “yes” initially. Once the survey/ballot is completed, you can set this to “no” which will cause it not to be displayed to your visitors, but will retain the results for your review in the future.
Once you are satisfied with this section, select “Save Properties and stay here”.
You are now ready to begin entering the specific survey questions. To do that, select the “Create New Survey/Ballot Item” link and you'll see a screen similar to the one below.
Item Text – enter the survey question in this area. The formatting bar may be used to format the text in this area.
Please note: If you change the item text after your vote/survey period has begun and people have started voting, earlier votes may not be recorded. If you need to change the wording on a ballot item after vote start coming in, please contact our support team for help
Online Voting Only - Below the item text, you'll see an option to allow write ins. Set 'yes' if you want to allow your users to write in responses (online voting feature only)
Number of picks allowed – is used to define how your visitor will respond to this question. All selections are made from the drop down menu. There are four unique pick types:
- Choose 1 only – which allows your visitor to select only one item from the choices available.
- Choose x or less (2-9) – which allows your visitor to make multiple selections, but not more than the maximum number you select.
- Choose all that apply – which allows your visitor to choose as many responses as they want.
- Choose exactly x (2-9) – which allows you visitor to choose the exact number of responses that you define.
When you are finished with this question, select “Save Properties and Return to Survey/Ballot” to continue the question defining process.
There is no limit to the number of questions you can include on a survey or ballot, nor is there any limit to the number of surveys/votes you create. There is, however, a limit to the patience of your site visitors. We strongly suggest that you keep your surveys/votes short – just a few questions – and don’t over-survey your customers!
Once your survey is “active” on your site, you will want to monitor the progress. To do that, select “Features” on the Admin Panel and “Manage” next to Surveys or Online Voting on the features screen. You will see a screen similar to the one shown below.
Select “View Results” to see a detailed report on the survey. Once the report is on the screen you can print it by selection “Printer Friendly” in the upper right corner of the screen and use your browser’s print capability (File/Print or Right Click/Print).
If you would like to remove the survey results, without deleting the survey, select “Delete Results”. This is useful if you plan to run the survey again later.
View Detailed Results
View Voting Log
There are a couple options when deleting a survey/ballot. Next to the 'view results' option, you can 'delete results'. If you would like to remove the survey results, without deleting the survey, select “Delete Results”. This is useful if you plan to run the survey again later.
Or, if you want to remove the survey/ballot entirely, just click the "delete" link for that survey. You'll see a confirmation screen similar to the one below

java.lang.Object org.apache.xalan.lib.Redirect
public class Redirect
Implements three extension elements to allow an XSLT transformation to redirect its output to multiple output files. It is accessed by specifying a namespace URI as follows:
xmlns:redirect="http://xml.apache.org/xalan/redirect"
You can either just use redirect:write, in which case the file will be opened and immediately closed after the write, or you can bracket the write calls by redirect:open and redirect:close, in which case the file will be kept open for multiple writes until the close call is encountered. Calls can be nested.
Calls can take a 'file' attribute and/or a 'select' attribute in order to get the filename. If a select attribute is encountered, it will evaluate that expression for a string that indicates the filename. If the string evaluates to empty, it will attempt to use the 'file' attribute as a default. Filenames can be relative or absolute. If they are relative, the base directory will be the same as the base directory for the output document. This is obtained by calling getOutputTarget() on the TransformerImpl. You can set this base directory by calling TransformerImpl.setOutputTarget() or it is automatically set when using the two argument form of transform() or transformNode().
Calls to redirect:write and redirect:open also take an optional attribute append="true|yes", which will attempt to simply append to an existing file instead of always opening a new file. The default behavior of always overwriting the file still happens if you do not specify append.
Note: this may give unexpected results when using xml or html output methods, since this is not coordinated with the serializers - hence, you may get extra xml decls in the middle of your file after appending to it.
Example:
<?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:redirect="http://xml.apache.org/xalan/redirect" extension-element-prefixes="redirect"> <xsl:template match="/"> <out> default output. </out> <redirect:open file="doc3.out"/> <redirect:write file="doc3.out"> <out> <redirect:write file="doc1.out"> <out> doc1 output. <redirect:write file="doc3.out"> Some text to doc3 </redirect:write> </out> </redirect:write> <redirect:write file="doc2.out"> <out> doc2 output. <redirect:write file="doc3.out"> Some more text to doc3 <redirect:write select="doc/foo"> text for doc4 </redirect:write> </redirect:write> </out> </redirect:write> </out> </redirect:write> <redirect:close file="doc3.out"/> </xsl:template> </xsl:stylesheet>

Match Play. Red leads 5-4 to 7. How should Red play 44?
pips Red=109 White=245
(CorrectAnswer= 0/0, ErrorScore= 0)
The point Red wants White to give up is his 3-pt, thus leaving White with a very poor 1-5 back game.
The best way to achieve this is 8/4(3), 6/2 so that all White’s fives except 53 must be played from the 3-pt. The alternative play of the odd-looking 8/4, 6/2(3) is the second-best play but that is still a big error.
The key in such situations is to work out how to damage your opponent’s back game. Here, 8/4(3), 6/2 does the most damage and so it easily gets the nod.

BBC Question Time man thinks his £80k salary is average in bizarre rant
The man claimed he was nowhere near the top 50% of earners in the country - despite his very healthy annual income. A clip of his rant on the BBC show quickly went viral last night.
by Abigail O'LearyA Question Time audience member went on a bizarre rant slamming tax increases - despite earning £80,000 a year.
The man criticised Labour's plans to tax the top 5% of earners in the country - insisting his healthy annual income was "nowhere near even the top 50%" of earners in the country.
He was later revealed to be an IT consultant and champion professional motorcycle racer.
Labour MP Richard Burgon and host Fiona Bruce went on to attempt to explain how those earning £80,000 are in fact in the top 5% of earners.
According to the most recent figures from the Office for National Statistics, an income of £75,300 places an earner in the top 5 per cent.
Under Labour's plan for a 45p rate on earnings over £80,000, he would pay an extra £4.81 per week if he earned £85,000 per year.
However, he continues his rant, saying: "I would like to call Labour out as liars.
Do you know the man? Email<EMAIL_ADDRESS>"I am one of them people he will tax more and I am nowhere near in the top five so I am calling you a liar.
"That 5% is a lie, I am nowhere near that and you are going to tax me as an employee.
"You are not going after the billionaires, you are going after the employees because it's easy money and I have no choice because its PAYE."
Burgon goes to say: "You are mistaken - we are not going to raise income tax apart from those in the top 5%.
"And thats why were not going to increase your income tax."
If the man earned £80,000 a year before tax, it would put him in the highest-earning 5% of taxpayers in the country - according to official government figures from 2016/17.
Under Labour, the man would have to pay roughly an extra £50 for every £1,000 he earns over £80,000 per year - excluding any other changes to the system.
However, the audience member continued his 'misjudged' rant - saying: "You are - I have read your policy and it's above £80,000."
"I am nowhere near the top 5% - I'm not even in the top 50%."
Fiona Bruce then interjected for clarification asking the man to confirm his income, to which she replies: "I think that is in the top 5%."
The audience member goes on to say the "top 5% don't even work because they're rich" - calling out "doctors" and "solicitors" as those who should be taxed more.
Question Time viewers took to Twitter calling out the audience member.
Josie Hall said: "God I would love to earn £80,000 a year!
"My husband and I run a 2 man business, work hard and earn not a fraction of that! Yet every year we pay Corporation tax and happy and willing to pay more so we are all secure! I just don't understand."

Jeremy Corbyn vowed yesterday to raise more than £80bn a year for his programme without raising Income Tax, VAT or National Insurance on 95% of people.
IFS think tank director Paul Johnson said it was "not credible" to say other earners would not be affected at all. He said: "You cannot raise that kind of money in our tax system without affecting individuals.”
But Mr Corbyn said the manifesto was fully costed - and stuffed with policies "the political establishment has blocked for a generation".


Man dies after falling in lava tube running under property
by Natalie Dreier, Cox Media Group National Content DeskA man living in Hawaii has died after he fell into a lava tube that ran through his property.
The man, who was not identified, had not been heard from for days and police were alerted, CNN reported.
When police searched his home in Kaumana, Hawaii, they found that he had fallen 22 feet below the surface into a lava tube, according to CNN.
Lava tubes are channels formed by nature where lava flows beneath the surface.
While the tubes snake under the Hawaiian islands, it is rare that someone falls into them, The Washington Post reported.
Police believe the man, who was in his 70s, was trimming branches when he sank through the soft ground over the tubes. Officials said there could have been a hole that the man couldn't see due to overgrowth, the Post reported.
Rescue teams recovered his body by rappelling into the lava tube, CNN reported.
The man died from injuries consistent with falling, police said.


Effect sender is an interface that allows you to send effects to be handled outside the handler when you use
HandlerWithEffects.
Handler is a function that receives the current state and an action that just happened and acts on it.
A function that on top of what Handler does, it also might emit side effects that are subscribed by an external
component.
Logger is a lambda you can provide to allow you to do some debugging using your favourite approach for it.
Interface that defines all the MVI logic of this library.
Extension of MVFlow to be used together with a HandlerWithEffects.
Reducer applies a Mutation to a State, returning the resulting State.

Some languages, such as C and C++, provide a way to define and invoke "preprocessor macros" which expand into strings of tokens. GDB can evaluate expressions containing macro invocations, show the result of macro expansion, and show a macro's definition, including where it was defined.
You may need to compile your program specially to provide GDB with information about preprocessor macros. Most compilers do not include macros in their debugging information, even when you compile with the `-g' flag. See section 4.1 Compiling for Debugging.
A program may define a macro at one point, remove that definition later, and then provide a different definition after that. Thus, at different points in the program, a macro may have different definitions, or have no definition at all. If there is a current stack frame, GDB uses the macros in scope at that frame's source code line. Otherwise, GDB uses the macros in scope at the current listing location; see 7.1 Printing Source Lines.
At the moment, GDB does not support the ##
token-splicing operator, the #
stringification operator, or
variable-arity macros.
Whenever GDB evaluates an expression, it always expands any macro invocations present in the expression. GDB also provides the following commands for working with macros explicitly.
macro expand expression
macro exp expression
macro expand-once expression
macro exp1 expression
info macro macro
macro define macro replacement-list
macro define macro(arglist) replacement-list
A definition introduced by this command is in scope in every expression
evaluated in GDB, until it is removed with the macro
undef
command, described below. The definition overrides all
definitions for macro present in the program being debugged, as
well as any previous user-supplied definition.
macro undef macro
macro define
command, described
above; it cannot remove definitions present in the program being
debugged.
macro list
macro define
command.
Here is a transcript showing the above commands in action. First, we show our source files:
$ cat sample.c #include <stdio.h> #include "sample.h" #define M 42 #define ADD(x) (M + x) main () { #define N 28 printf ("Hello, world!\n"); #undef N printf ("We're so creative.\n"); #define N 1729 printf ("Goodbye, world!\n"); } $ cat sample.h #define Q < $ |
Now, we compile the program using the GNU C compiler, GCC. We pass the `-gdwarf-2' and `-g3' flags to ensure the compiler includes information about preprocessor macros in the debugging information.
$ gcc -gdwarf-2 -g3 sample.c -o sample $ |
Now, we start GDB on our sample program:
$ gdb -nw sample GNU gdb 2002-05-06-cvs Copyright 2002 Free Software Foundation, Inc. GDB is free software, ... (gdb) |
We can expand macros and examine their definitions, even when the program is not running. GDB uses the current listing position to decide which macro definitions are in scope:
(gdb) list main 3 4 #define M 42 5 #define ADD(x) (M + x) 6 7 main () 8 { 9 #define N 28 10 printf ("Hello, world!\n"); 11 #undef N 12 printf ("We're so creative.\n"); (gdb) info macro ADD Defined at /home/jimb/gdb/macros/play/sample.c:5 #define ADD(x) (M + x) (gdb) info macro Q Defined at /home/jimb/gdb/macros/play/sample.h:1 included at /home/jimb/gdb/macros/play/sample.c:2 #define Q < (gdb) macro expand ADD(1) expands to: (42 + 1) (gdb) macro expand-once ADD(1) expands to: once (M + 1) (gdb) |
In the example above, note that macro expand-once
expands only
the macro invocation explicit in the original text -- the invocation of
ADD
-- but does not expand the invocation of the macro M
,
which was introduced by ADD
.
Once the program is running, GDB uses the macro definitions in force at the source line of the current stack frame:
(gdb) break main Breakpoint 1 at 0x8048370: file sample.c, line 10. (gdb) run Starting program: /home/jimb/gdb/macros/play/sample Breakpoint 1, main () at sample.c:10 10 printf ("Hello, world!\n"); (gdb) |
At line 10, the definition of the macro N
at line 9 is in force:
(gdb) info macro N Defined at /home/jimb/gdb/macros/play/sample.c:9 #define N 28 (gdb) macro expand N Q M expands to: 28 < 42 (gdb) print N Q M $1 = 1 (gdb) |
As we step over directives that remove N
's definition, and then
give it a new definition, GDB finds the definition (or lack
thereof) in force at each point:
(gdb) next Hello, world! 12 printf ("We're so creative.\n"); (gdb) info macro N The symbol `N' has no definition as a C/C++ preprocessor macro at /home/jimb/gdb/macros/play/sample.c:12 (gdb) next We're so creative. 14 printf ("Goodbye, world!\n"); (gdb) info macro N Defined at /home/jimb/gdb/macros/play/sample.c:13 #define N 1729 (gdb) macro expand N Q M expands to: 1729 < 42 (gdb) print N Q M $2 = 0 (gdb) |

A useless thing is envy;
A foolish thing to boot.
Why should a Fox who has a bark
Want like an Owl to hoot?
Whitefoot was beginning to feel quite at home. He would have been wholly contented but for one thing,—he had no well-filled storehouse. This meant that each day he must hunt for his food.
It wasn’t that Whitefoot minded hunting for food. He would have done that anyway, even though he had had close at hand a store-house with plenty in it. But he would have felt easier in his mind. He would have had the comfortable feeling that if the weather turned so bad that he could not easily get out and about, he would not have to go hungry.
But Whitefoot is a happy little fellow and wisely made the best of things. At first he came out very little by day. He knew that there were many sharp eyes watching for him, and that he was more likely to be seen in the light of day than when the Black Shadows had crept all through the Green Forest.
He would peek out of his doorway and watch for chance visitors in the daytime. Twice he saw Butcher the Shrike alight a short distance from the tree in which Timmy lived.  Once he saw Whitey the Snowy Owl and so knew that Whitey had not yet returned to the Far North. Once Reddy Fox trotted along right past the foot of the old stub in which Whitefoot lived, and didn’t even suspect that he was anywhere near. Twice he saw Old Man Coyote trotting past, and once Terror the Goshawk alighted on that very stub, and sat there for half an hour.
So Whitefoot formed the habit of doing just what Timmy the Flying Squirrel did; he remained in his house for most of the day and came out when the Black Shadows began to creep in among the trees. Timmy came out about the same time, and they had become the best of friends.
Now Whitefoot is not much given to envying others, but as night after night he watched Timmy a little envy crept into his heart in spite of all he could do. Timmy would nimbly climb to the top of a tree and then jump. Down he would come in a long beautiful glide, for all the world as if he were sliding on the air.
The first time Whitefoot saw him do it he held his breath. He really didn’t know what to make of it. The nearest tree to the one from which Timmy had jumped was so far away that it didn’t seem possible any one without wings could reach it without first going to the ground.
“Oh!” squeaked Whitefoot.   He’ll break his neck!” But Timmy did nothing of the kind. He sailed down, down, down and alighted on that distant tree a foot or two from the bottom; and without stopping a second scampered up to the top of that tree and once more jumped. Whitefoot had hard work to believe his own eyes. Timmy seemed to be jumping just for the pleasure of it. As a matter of fact, he was. He was getting his evening exercise.
Whitefoot sighed. “I wish I could jump like that,” said he to himself. “I wouldn’t ever be afraid of anybody if I could jump like that. I envy Timmy. I do so.”

The idea came from the owner Pat when he has come up with a business idea by combining two signature Seattle icons. Pat has developed a recipe for a coffee-time confection called Salmon Cookies. These cookies made into the shape of a salmon that has just a hint of fishy goodness.
We have a wide variety of products from the infamous Salmon cookies, the cutters to try to make your own and merch to show your love for the cookies such as t-shirts and fish stickers.


Reactime is a debugging tool for React developers. It records state whenever it is changed and allows the user to jump to any previously recorded state.
This tool is for React apps using stateful components and prop drilling, and has beta support for Context API, conditional state routing, Hooks (useState, useEffect) and functional components.
The latest release extends the core functionality by including support for TypeScript applications, improving the user experience through more declarative titles in the actions panel, and extending support for components with conditional state fields. The testing suite has also been expanded with the inclusion of a Sandbox utility to aid future expansion as well as additional E2E and integration tests with Puppeteer and React Testing Library.
After installing the Reactime, you can test its functionalities in the following demo repositories:
Reactime was nominated for the Productivity Booster award at React Open Source Awards 2020!
Just one step needed Chrome extension and an NPM package.
src/extension/build/build.zip
for manual installation in Developer mode. Turn on 'Allow access to file URLs' in extension details page if testing locally.* for old version instaling click here *
After installing both the Chrome extension and the NPM package, just open up your project in the browser.
Then open up your Chrome DevTools and navigate to the Reactime tab.
Whenever state is changed (whenever setState or useState is called), this extension will create a snapshot of the current state tree and record it. Each snapshot will be displayed in Chrome DevTools under the Reactime panel.
You can click on a snapshot to view your app's state. State can be visualized in a JSON or a tree. Also, snapshots can be diffed with the previous snapshot, which can be viewed under the Diff tab.
Jumping is the most important feature of all. It allows you to jump to any previous recorded snapshots. Hitting the jump button on any snapshot will change the DOM by setting their state.
Reactime offers beta support for TypeScript applications using stateful class components and functional components with useState hooks. Further testing and development is required for custom hooks, Context API, and Concurrent Mode.

In some cases, you may want to keep the majority of the locale settings in your language packs, but still change some of them programmatically based on certain server-side conditions.
The way this works is the following - if a specific value for a property is not specified in PHP code, the default from the language pack will be used. If it is specified in code however, it will override the language pack default.
Not all texts can be set dynamically.
A example for this is customizing the 'all-day' text. Using setOptions method for the allDayText variable we can overwrite the text.
<?php
...
$eventcal = new jqScheduler($conn);
...
$eventcal->setOptions(array(
'allDayText'=>'All Day'
));
...
?>

template<typename MT1, typename MT2>
class blaze::TSMatSMatSchurExpr< MT1, MT2 >
Expression object for transpose sparse matrix-sparse matrix Schur products.
The TSMatSMatSchurExpr class represents the compile time expression for Schur products between a column-major sparse matrix and a row-major sparse matrix.
◆ anonymous enum
template<typename MT1 , typename MT2 >
Compilation switch for the selection of the subscript operator return type.
The returnExpr compile time constant expression is a compilation switch for the selection of the ReturnType. If either matrix operand returns a temporary vector or matrix, returnExpr will be set to false and the subscript operator will return it's result by value. Otherwise returnExpr will be set to true and the subscript operator may return it's result as an expression.

B.C. to restrict nicotine content, bring in 20% tax on vaping products
Province will also restrict candy and fruit flavoured vaping products to adult-only stores
by Katya SlepianE-cigarettes sold in B.C. will have to follow a lot more regulations as of 2020.
In an announcement Thursday, Health Minister Adrian Dix said vaping products sold in B.C. stores will have limits on the amount of nicotine, be subject to a 20 per cent tax, and restrict where candy and fruit flavours are sold.
Dix said the move was sparked by a 74 per cent spike in vaping among high school aged youth between 2017 and 2018. It’s illegal to sell vaping products in B.C. to anyone under the age of 19.
“If you have not been vaping, vaping is not a good idea,” Dix said on Thursday.
Nicotine levels for vaping products sold in B.C. will be restricted to 20 milligrams per millimetre, based on research from other jurisdictions, Dix said.
He cited the United Kingdom, which has the same restrictions and much lower levels of youth vaping.
Dr. Khairun Jivani, the director of cancer control for the B.C. and Yukon branch of the Canadian Cancer Society, said studies show that one in five youth have vaped in the past 30 days.
There are currently seven probable and confirmed cases of vaping-related illness in Canada. That includes three probable cases in B.C., the most of any province.
Dix said the province will declare nicotine a “public health hazard,” which will allow them to regulate the amount of nicotine in vaping products sold in B.C.

Jivani said the change is important because nicotine is highly addictive.
“Nicotine devices have high levels of nicotine, as much as a pack of cigarettes,” she said.
“We know that nicotine can alter brain function… and lead to cognitive and behavioural problems.”
Jivani also cited chemicals in vaping products that are approved for use in food, but have not been studied when they are vapourized in e-cigarettes.
Youth who use vaping products also have a higher rate of moving onto tobacco, Jivani noted.
Finance Minister Carole James said the 20 per cent tax on vaping products would be the first such tax in Canada. If passed, the 13 per cent increase in the provincial sales tax for vaping products will come into effect on Jan. 1, 2020.
If passed, the measure is expected to bring in $2.5 million this fiscal year, and $10 million in the 2020-2021 year. The tax on tobacco products generates about $25 million per fiscal year.
James noted that the vaping tax hike is not meant to generate revenue, but increase the price enough to act as a deterrent.
Dix said that the restrictions on fruit and candy flavoured will cut down the number of stores in B.C. where non-tobacco flavoured products can be sold from 90,000 potential locations to a somewhere in the hundreds. Some vaping flavours will be fully banned, Dix said, but declined to elaborate on what those will be.
None of these rules will apply to vaping products sold online, as that is regulated federally. Dix said the province was hoping the feds would bring in similar regulations nationwide as B.C. has here.
Health Canada did not immediately respond to a request for comment.
Education Minister Rob Fleming said age-appropriate resources will be brought into schools as part of a vaping prevention toolkit.
Fleming told reporters that young people had been “conned and duped by big tobacco when it comes to vaping.”
Fleming said there are a “bunch of myths out there… that vaping isn’t smoking, that vaping isn’t addictive, that vaping is not linked to cancer.”
He said that where the vaping industry either actively perpetuated these beliefs, or made sure not to discourage them.

Mombacho Gold Pure Honey is a unique gourmet experience that provides an exuberant and exotic touch when savored just by itself, or when added to beverages and desserts. Mombacho Gold has been used internationally by outstanding chefs to enhance their most cherished recipes. In the USA, Chef David Guas of Acadiana Restaurant in Washington, D.C. used Mombacho Gold to prepare his torrejas in NBC´s Today’s Kitchen program.
What makes our honey special is the variety of wild flowers from which our bees gather their raw material, as well as the natural method our family-owned company uses to bring the product to the final consumer. Our honey’s name comes from its source of origin, Mombacho Volcano Nature Reserve, a majestic mountain covered by an enchanted elfin forest. Rising towards the clouds, Mombacho is located in Granada, Nicaragua, besides the largest Neo Tropical fresh water lake, where earth’s nature diversity is at its greatest.
While most honeys are derived from only one kind of flower, ours comes from a mixture of exotic varieties that thrive on Mombacho´s permanently moist, rich soil. There, one can find all sorts of living beings, including hummingbirds, butterflies and bees, feeding on the nectar and pollen of wild orchids, heliconias, and bromeliads. Thus, the honey processed by our bees put you in contact with Nature in its more pristine state, and it brings you a piece of our Magic Mountain.
After our bees have gathered and processed the nectar from Mombacho´s wild flowers, honey is extracted in our nearby farm, Hacienda La Calera, and left to settle in specially designed containers without any additional processing. Unlike strained or filtered honey, ours contains a large presence of compounds that function as antioxidants, such as chrysin, pinobanksin, vitamin C, catalase, and pinocembrin. Because of honey’s relatively acidic pH level, growth of is prevented. Once our honey settles into a clear, golden colored fluid, it is bottled under our family’s supervision.
When savoring this nectar, you will enjoy this unique Mombacho Neo Tropical experience!

--- layout: post title: Numpy - Get Started category: data-wrangling tag: [python, numpy] --- {% include JB/setup %}
NumPy is the fundamental package for scientific computing with Python. It is a Python library that provides a multidimensional array object, various derived objects (such as masked arrays and matrices), and an assortment of routines for fast operations on arrays, including mathematical, logical, shape manipulation, sorting, selecting, I/O, discrete Fourier transforms, basic linear algebra, basic statistical operations, random simulation and much more. It allows data sciebtists to easily implement methmatically concept into code. Most importantly, Numpy arrays are really fast and friendly on CPU and RAM.
Below is a note for basic usage of numpy.
import numpy as np
As you can see below, you can operate A
with mathmatically operations like addition, extraction, power, squart, log etc.
Python List L
cannot. It will need to do looping
on each element to achieve the same and hence it's way too slow.
# Python List
L = [1, 2, 3]
A = np.array([1, 2, 3])
# You can operate A with mathmatically operation. L cannot.
print(2*A)
print(A**2)
print(np.sqrt(A))
print(np.log(A))
An important operation for array is dot product as it's basic for matrix operation. Below are the various ways to achieve it.
In code below, dot product for $a$ and $b$ should be like $a\cdot b^{T}= 1*3+2*4=11$.
a = np.array([1, 2])
b = np.array([3, 4])
# dot product in different ways:
np.dot(a, b) # 11
np.inner(a, b) # 11. dot product is also inner product
a.dot(b) # 11
b.dot(a) # 11
(a*b).sum() # 11
# you can use python looping to achieve the same, but it will be extremely slow when data is huge.
dot = 0
for i, j in zip(a, b):
dot += i*j
print(dot) # 11
We can still use np.array to product Matrix. Below is the code for various operations on matrix.
# Note you can also use np.matrix but np.array is recommanded officially.
M = np.array([[1, 2], [3, 4]])
# extract element
M[0][0] # 1 ; this is the same as python list
M[0, 0] # 1
# matrix transport
M.T
# get shap
M.shap
# Matrix product. same as dot product
M.dot(M)
np.inner(M, M)
# inverse matrix
np.linalg.inv(M)
# determination
np.linalg.det(M)
# diagonal element
np.diag(M) # [1, 4]
# note this will rerurn diagonal matrix
np.diag([1, 4]) # [[1, 0], [0, 4]]
# trace
np.diag(M).sum()
np.trace(M)
# product various 10x10 matrix
# all zero
Z = np.zeros((10, 10))
# all one
O = np.ones((10, 10))
# random from uniform distribution
R = np.random.random((10, 10))
# random from normal distribution(0, 1)
# Note randn take each dimension as individual argument, others use turple
N = np.random.randn(10, 10)
print(N.mean())
print(N.var())


Percentage of housing units within ½-mile of a full-service, chain grocery store
Healthy food and physical activity are essential for combating obesity, reducing preventable chronic diseases and promoting overall healthy living. Grocery stores can provide access to a greater variety of cheaper and healthier foods, including fresh fruits and vegetables, helping to facilitate healthier dietary choices. While they are not included here, Farmers' markets provide another source of community access to fresh, locally produced fruits, vegetables and other food products, and may be particularly important in areas poorly served by full-service grocery stores. Proximity to a grocery store is only one aspect of accessibility. Other factors that affect access are cost, hours of operation, transportation, and geographic barriers such as major highways.
####How are we doing? Overall, 32% of housing units in Mecklenburg County had proximity to a chain grocery store in 2014, up from 27% in 2011. The total number of full-service, chain grocery stores in Mecklenburg County increased from 141 in 2011 to 156 in 2014.
####Did you know? In 2013, 63% of people in Mecklenburg County were medically overweight or obese, 19% experienced food insecurity over the past year, and 7% of low- and moderate-income households had limited access to healthy foods. Through community-wide action planning, the Mecklenburg County Health Department is working to improve access to healthy foods and food choices through: building community and school gardens, working to have SNAP benefits accepted at farmer's markets, attracting full-service grocery stores to food deserts and improving healthy school lunch and vending machine choices.
####Related variables

Resources and Styles in Xamarin.Forms (XAM140)
Using the same fonts and colors across your entire UI creates a consistent look-and-feel. Xamarin.Forms provides a way to define these values in one place and look them up everywhere they are used; this guarantees consistency across your app and makes updates simple. This course shows you how to define and apply a Resource both in code and in XAML. It also shows you how to group multiple settings into a Style so you can apply them all at once.
Recommended prerequisite for this course
Upon completion you will be able to:
- Avoid duplicate XAML with Resources
- Create consistent UI with Styles
- Make your Resources and Styles available across your entire app
- Apply the user's accessibility choices with built-in Styles

-
Exercise 6: Use application-wide resources
The goal of this exercise is to make resources available across multiple pages by moving them to a resource dictionary in your app class.


Intro
Currently there are two key ways in connecting to Athena from R, using the ODBC and JDBC drivers. To access ODBC driver R users can use the excellent odbc package supported by Rstudio. To access the JDBC driver R users can either use RJDBC or helpful wrapper package AWR.Athena which wraps the RJDBC package to make the connection to Athena through the JDBC driver simpler. These methods are an excellent way for R to connect to Athena, however is there another way?
 Ever since the reticulate pacakge was developed (by Rstudio) the interface into Python from R has never been simpler. This makes another route into Athena possible! Amazon has developed a Python software developement kit (SDK) called Boto3. By using boto3
in combination with the R package reticulate
a new method into accessing Athena can be made possible. Introducing the R package RAthena.
RAthena
- What is RAthena?
Rathena
is a R package that creates a DBI (Database Interface) for the R package DBI by usingBoto3
as the backend.
- Why was RAthena created when there are already methods for connecting to Athena?
RAthena
was created to provide an extra method to connect to Athena for R users. Nothing more, nothing less.
- Why is RAthena call RAthena?
Isn’t it obvious? Most R packages that interfaces with databases are called
"R<database>"
for exampleRSQLite
,RPostgreSQL
, etc… Plus this package is “roughly” the R equivalent to the superbPython
package PyAthena. So calling this pacakgeRAthena
seems like the best fit.
Getting Started
Now lets get into how to actually use RAthena
. I am going to skip over the part were you have to set up an Amazon Web Services Account (AWS Acount) and get straight into the good stuff.
Before working with RAthena
, Python 3+ is require. Please install it directly or use the Anaconda Distribution.
Now we have Python 3+
we now need to install Boto3
. If you installed Python 3+
with the Anaconda Distribution I believe Boto3
comes as standard, if so then you can skip this step, but for everyone else you can install Boto3
either by the pip
command or the inbuilt installation function in RAthena
.
pip command:
pip install boto3
RAthena
installation function:
RAthena::install_boto()
Usage
Connecting to Athena
Now we have everything that is required we are now ready to connect to Athena
. RAthena
provides several method to connect to Athena
ranging from hard-coding credentials to using Amazon Role Name Roles (ARN roles).
Hard-Coding Method:
This method isn’t recommended as your credentials are hard-coded.
library(DBI)
con <- dbConnect(RAthena::athena(),
aws_access_key_id = "<YOUR AWS KEY ID>",
aws_secret_access_key = "<YOUR SECRET ACCESS KEY>",
s3_staging_dir = "<LOCATION FOR ATHENA QUERY OUTPUT>")
Note: s3_staging_dir
requires the be the format of s3 uri
for example “s3://path/to/query/bucket/”
Environment Variable Method:
RAthena
supports setting AWS credentials into environment variables to avoid hard-coding. From what I have found out an easy way to set up environment variables (that persists) in R is to use the file.edit
function like so:
file.edit("~/.Renviron")
And now you can simply add in your variables to the file for example:
AWS_ACCESS_KEY_ID = <YOUR AWS KEY ID>
Once you have set your environment variables you can connect to Athena in the following method:
library(DBI)
con <- dbConnect(RAthena::athena(),
s3_staging_dir = "<LOCATION FOR ATHENA QUERY OUTPUT>")
AWS Profile Names:
Another method is to use AWS Profile Names. AWS profile names can be set either manually in the ~/.aws
directory or by using the AWS Command Line Interface (AWS CLI). Once you have set up your profile name you can connect to Athena
:
Using Default Profile Name:
library(DBI)
con <- dbConnect(RAthena::athena(),
s3_staging_dir = "<LOCATION FOR ATHENA QUERY OUTPUT>")
Using Non-Default Profile Name:
library(DBI)
con <- dbConnect(RAthena::athena(),
profile_name = "rathena",
s3_staging_dir = "<LOCATION FOR ATHENA QUERY OUTPUT>")
ARN Roles:
ARN roles are fairly useful if you need to assume a role that can connect to another AWS account and use the Athena
in that account. Or whether you want to create a temporary connection that will expire (there are other reasons why to use ARN roles please check them out in the AWS documentation).
Creating ARN role credentials before connecting to Athena:
library(RAthena)
library(DBI)
assume_role(profile_name = "YOUR_PROFILE_NAME",
role_arn = "arn:aws:sts::123456789012:assumed-role/role_name/role_session_name",
set_env = TRUE)
# Connect to Athena using ARN Role
con <- dbConnect(athena(),
s3_staging_dir = "s3://path/to/query/bucket/")
Connect to Athena directly using ARN role:
library(DBI)
con <- dbConnect(athena(),
profile_name = "YOUR_PROFILE_NAME",
role_arn = "arn:aws:sts::123456789012:assumed-role/role_name/role_session_name",
s3_staging_dir = 's3://path/to/query/bucket/')
Note: ARN Roles have a duration timer before they will expirer. To change the default you can increase the duration_seconds
parameter from the default 3600 seconds (1 hour).
Temporary Sessions:
Finally you can create temporary credentials before connecting to Athena
.
library(RAthena)
library(DBI)
# Create Temporary Credentials duration 1 hour
get_session_token("YOUR_PROFILE_NAME",

# Connect to Athena using temporary credentials
con <- dbConnect(athena(),
s3_staging_dir = "s3://path/to/query/bucket/")
Note: This method will work for users who have set up Multi-Factor Authentication (MFA).
Basic Usage
Now we have created a connection to Athena
we can ulitise DBI
methods to query Athena
for example:
All avialable tables in Athena:
dbListTables(con)
Send Query to Athena
res <- dbSendQuery(con, "SELECT * FROM INFORMATION_SCHEMA.COLUMNS")
dbFetch(res)
dbClearResult(res)
Or …
res <- dbExecute(con, "SELECT * FROM INFORMATION_SCHEMA.COLUMNS")
dbFetch(res)
dbClearResult(res)
Or …
dbGetQuery
wraps sending, fetching and clearing results in one easy step.
dbGetQuery(con, "SELECT * FROM INFORMATION_SCHEMA.COLUMNS")
Note: You might of noticed that if you have data.table
installed RAthena
will attempt to return the data as a data.table
. This is to improve speed when larger queries are returned from Athena
. If you don’t have data.table
, RAthena
will return the output as a data.frame
.
Get Column information
res <- dbSendQuery(con, "SELECT * FROM INFORMATION_SCHEMA.COLUMNS")
dbColumnInfo(res)
dbClearResult(res)
To learn about what DBI
methods have been implemented in RAthena
please refer to: link.
Intermediate Usage:
It is all very well querying data from Athena
but what is more useful is to upload data as well. RAthena
has addressed this and implemented a method in dbWriteTable
dbWriteTable(con, "mtcars", mtcars,
partition=c("TIMESTAMP" = format(Sys.Date(), "%Y%m%d")),
s3.location = "s3://mybucket/data/")
Once you have uploaded data into Athena
you can query it like the following:
dbGetQuery(con, "select * from mtcars")
Here are all variable parameters for the dbWriteTable
method:
conn: An AthenaConnection object, produced by dbConnect()
name: A character string specifying a table name. Names will be automatically quoted so you can use any sequence of characters, not just any valid bare table name.
value: A data.frame to write to the database.
overwrite: Allow overwriting the destination table. Cannot be ‘TRUE’ if ‘append’ is also ‘TRUE’.
append: Allow appending to the destination table. Cannot be ‘TRUE’ if ‘overwrite’ is also ‘TRUE’.
row.names: Either TRUE, FALSE, NA or a string. If TRUE, always translate row names to a column called “row_names”. If FALSE, never translate row names. If NA, translate rownames only if they’re a character vector. A string is equivalent to TRUE, but allows you to override the default name. For backward compatibility, NULL is equivalent to FALSE.
field.types: Additional field types used to override derived types.
partition: Partition Athena table (needs to be a named list or vector) for example: c(var1 = “2019-20-13”)
s3.location s3 bucket to store Athena table, must be set as a s3 uri for example (“s3://mybucket/data/“)
file.type: What file type to store data.frame on s3, RAthena currently supports [“csv”, “tsv”, “parquet”]. Note: file.type “parquet” is supported by R package
arrow
and will need to be installed seperately if you wish to upload data.frames in “parquet” format.…: Other arguments used by individual methods.
Tidyverse Usage:
RAthena
can integrate with the famous R package dplyr.
library(DBI)
library(dplyr)
con <- dbConnect(RAthena::athena(),
profile_name = "rathena",
s3_staging_dir = "<LOCATION FOR ATHENA QUERY OUTPUT>")
tbl(con, sql("SELECT * FROM INFORMATION_SCHEMA.COLUMNS"))
Or if you have already uploaded a table into Athena
tbl(con, "mtcars")
Conclusion
So hopefully this has given you an insight into the up coming package RAthena
and it’s usefulness. This package is not meant to replace any of the other packages that connect into Athena
but give another route into Athena
for R users.
Final note: RAthena
offers alot more functionality please check it out at Github. If you have any suggestions please raise an issue at Github Issues.
