If enabled then processing each splitted messages occurs concurrently. Note the caller thread will still wait until all messages has been fully processed before it continues. Its only processing the sub messages from the splitter which happens concurrently.
Sets a reference to the AggregationStrategy to be used to assemble the replies from the splitted messages into a single outgoing message from the Splitter. By default Camel will use the original incoming message to the splitter (leave it unchanged). You can also use a POJO as the AggregationStrategy
This option can be used to explicit declare the method name to use when using POJOs as the AggregationStrategy.
If this option is false then the aggregate method is not used if there was no data to enrich. If this option is true then null values is used as the oldExchange (when no data to enrich) when using POJOs as the AggregationStrategy
Refers to a custom Thread Pool to be used for parallel processing. Notice if you set this option then parallel processing is automatic implied and you do not have to enable that option as well.
When in streaming mode then the splitter splits the original message on-demand and each splitted message is processed one by one. This reduces memory usage as the splitter do not split all the messages first but then we do not know the total size and therefore the link org.apache.camel.ExchangeSPLIT_SIZE is empty. In non-streaming mode (default) the splitter will split each message first to know the total size and then process each message one by one. This requires to keep all the splitted messages in memory and therefore requires more memory. The total size is provided in the link org.apache.camel.ExchangeSPLIT_SIZE header. The streaming mode also affects the aggregation behavior. If enabled then Camel will process replies out-of-order eg in the order they come back. If disabled Camel will process replies in the same order as the messages was splitted.
Will now stop further processing if an exception or failure occurred during processing of an org.apache.camel.Exchange and the caused exception will be thrown. Will also stop if processing the exchange failed (has a fault message) or an exception was thrown and handled by the error handler (such as using onException). In all situations the splitter will stop further processing. This is the same behavior as in pipeline which is used by the routing engine. The default behavior is to not stop but continue processing till the end
Sets a total timeout specified in millis when using parallel processing. If the Splitter hasn't been able to split and process all the sub messages within the given timeframe then the timeout triggers and the Splitter breaks out and continues. Notice if you provide a TimeoutAwareAggregationStrategy then the timeout method is invoked before breaking out. If the timeout is reached with running tasks still remaining certain tasks for which it is difficult for Camel to shut down in a graceful manner may continue to run. So use this option with a bit of care.
Uses the Processor when preparing the org.apache.camel.Exchange to be send. This can be used to deep-clone messages that should be send or any custom logic needed before the exchange is send.
Shares the org.apache.camel.spi.UnitOfWork with the parent and each of the sub messages. Splitter will by default not share unit of work between the parent exchange and each splitted exchange. This means each splitted exchange has its own individual unit of work.
If enabled then the aggregate method on AggregationStrategy can be called concurrently. Notice that this would require the implementation of AggregationStrategy to be implemented as thread-safe. By default this is false meaning that Camel synchronizes the call to the aggregate method. Though in some use-cases this can be used to archive higher performance when the AggregationStrategy is implemented as thread-safe.

Facebook Bug Has Camera Activated While People Are Using the App
by msmashWhen you're scrolling through Facebook's app, the social network could be watching you back, in more ways than just your data, concerned users have found. Multiple people have found and reported that their iPhone cameras were turned on in the background while looking at their feed. From a report: The issue came to light with several posts on Twitter, showing that their cameras were activated behind Facebook's app as they were watching videos or looking at photos on the social network. After clicking on the video to full screen, returning it back to normal would create a bug where Facebook's mobile layout was slightly shifted to the right. With the open space on the left, you could now see the phone's camera activated in the background. This was documented in multiple cases, with the earliest incident on November 2.


Chrissy Teigen Brags About Having 'Boned' the Sexiest Man Alive
American model, TV host, and social media star Chrissy Teigen, 33, has long been known as a Twitter and Instagram influencer, sharing her witty and humorous thoughts about politics, her private life and of course, her husband John Legend.
Singer John Legend was named 2019’s Sexiest Man Alive by People magazine on 12 November, while serving as a judge on the TV show The Voice.
Legend, 40, was introduced as the new titleholder by 2017’s Sexiest Man Alive, Blake Shelton, 43.
Chrissy Teigen promptly gushed about her husband’s success on Twitter, following People labelling Legend the sexiest man alive.
The singer has told the magazine he was thrilled to receive such a title.
"I was excited, but I was a little scared at the same time because it’s a lot of pressure', he told People magazine. "Everyone’s going to be picking me apart to see if I’m sexy enough to hold this title. I’m [also] following Idris Elba, which is not fair and is not nice to me!"
Teigen has made more jokes about being married to "the sexiest man" on the planet. She even updated the bio in her Twitter account which now says "de-motivational speaker currently sleeping with people's sexiest man alive".
The 10-time Grammy winner is the third coach on The Voice to become the titleholder following Blake Shelton in 2017 and Adam Levine in 2013.


I've always wanted to try shrooms, so when the opportunity came up, I had to jump on it. I live in an area where it's pretty hard to get shrooms- they only come around every few months. So I bought a bunch and got together with my girlfriend and two friends. We were at my house, so the location was comfortable. I read that this was very important. I also read that a good positive attitude was important. So we all did our best to stay happy the few days before d-day.
D-day came. We measured out around 1.5g for each of us. I wish I had used a better scale, because I think that I might have gotten more (like 2-2.5.)
After smoking a few bowls to chill out and get the munchies, we were ready to shroom!
We put them on a peanut butter sandwich with honey and chowed down. The honey was a big help.  They were so dry that they didn't really smell like anything, let alone taste bad. All I knew was that the pot wanted me to eat the yummy honey and peanut butter sandwich.
I've read a lot of bad things about these types of drugs, and plenty of stories (on this site even) about people going nuts from one trip. So needless to say I was DAMN nervous, despite my positive mood.
It only took 20 minutes for me to start feeling it. The drapes started to flow. I pointed this out to my companions, and they just laughed. I started describing everything that was happening, and they told me to be quiet.
(Note: most of this is but a very vague memory. I have trouble remembering dreams, and most of this felt like a dream.)
For whatever reason, tears started to come out. Just as I was starting to peak, my friends felt their onset.
I got pretty upset and my girlfriend led me to my room. I lay on the bed and started salivating on myself. I couldn't even talk -- all that would come out is moans. I remember simply wanting it all to go away.
It was like each and every part of my brain was thinking in overdrive. Every aspect of life was being processed at once. I thought of myself as millions of atoms. I looked up at my clock and couldn't understand the concept of counting. Nothing made sense.. it was horrible. I called my girlfriend in and she lay down with me. She turned the lights out.
 My brain was going 1000mph and demanded things to process.
All kinds of crazy thoughts. GF summed it up when after 20 minutes she sat up and said 'I think I just went to another dimension.'
After that everything was fine. We joined my friend and concluded that 'you make your own reality. we should be celebrating!'
Life couldn't have been better- we all were in some sort of europhoric happy-ville. Things looked neat. I remember looking at some art book and loving it, but that's about it. The rest of what I remember is very small fragments -- My dog looking like a painting, the TV being in 3d, the walls flowing and breathing. Lots of cool visuals!
But that's about it. I don't even remember having sex. :(
I think the first half of my trip was bad because I was the first one in. Nobody there had ever done it before, so they really didn't know what to say to me when I was freaking out. The peak was REALLY overwhelming..information overload. I had definitely lost all control to the trip and sat in the back of the bus. 6 hours went by after my peak and I only remember maybe a collective minute of it.
We DID smoke some more, though. I do remember that. I forget a lot when I'm stoned, so I'm betting that's what did it. (That's something to consider when thinking about having a first trip. I definitely recommend NOT doing any other drugs.)

int year = 2019;
Programming elements like 2019 called Literal. A value of a specific data type is generated from the literal. Every programming language has its own set of literals. Mostly, values are created with the same type as a literal.
The programming elements as the year called Variable. A variable is a storage location with a name in order to save the value. The size of storage capacity varies depending on the Data Type.
Data type in Java is divided into two types.
Primitive Data Types are a Data Type for normal data. Reference Data Types are a Data Type for reference data.
Primitive Data Types are boolean, char, byte, short, int, long, float, and double.
The boolean data type has only two possible values: true and false.
boolean signIn = true;
The char data type is a single 16-bit Unicode character. Always use 'single quotes' for char literals. The following example expresses characters, unicode characters, and control characters using single quotation marks ('').
char grade = 'A'; char ch = '\uFFFF'; ('\uFFFF' is the character correspond to FFFF (Hex) in UTF-16) char ech = '\n';//line feed char ech = '\b';//backspace char ech = '\t';//tab char ech = '\\';//backspace char ech = '\"';//double quote char ech = '\'';//single quote
The byte data type is an 8-bit integer.
byte weight = 71;
The short data type is a 16-bit integer.
short bill = 30000;
The int data type is a 32-bit integer.
int balance = 56219618;
The long data type is a 64-bit two's complement integer. Numbers with an L at the end are long type literals.
long balance = 56219618L;
The float data type is a 32-bit floating point. Numbers with f at the end are float type literals.
long rate = 6.195f;
The double data type is a 64-bit floating point.
long rate = 6.195;
The following is an explanation of how the data type of the value is determined.
int i1 = 3;//integral number without any additional character is a int literal. long l1 = 4;//4 is an int literal.
Mostly, values of the same type as the literal type are created. However, an int literal can be a byte or short-form value. Consider the following example.
byte b = 1; //1 is an int literal, but it is a byte value. short s = 2; //2 is an int literal, but it is a short value.
Java requires these rules because there are no special literals for bytes and shorts.
Not all literals are a value.
int i2 =<PHONE_NUMBER>; //compile error
3000000000 (3 billion) is an int literal, but out of the int range. As a result, an int value is not created and a compilation error occurs.
An integer number followed by an L is a long literal.
long l2 =<PHONE_NUMBER>L; //3000000000L is a long literal.
Numbers with decimal point or numbers followed by an D or d are double literal.
double d1 = 3.14; //3.14 is a double literal. double d2 = 3.14D; //3.14D is a double literal. double d3 = 3.14d; //3.14d is a double literal. float f1 = 3.14; //compile error. A double type value can not be assigned to a float type variable.
Numbers followed by f are float literal.
float f2 = 3.14f; //3.14f is a float literal.
In a Java variable declaration, you must put the data type before the variable.
Student john = new Student();
Student is the data type of the variable john and Student is not primitive data type. therefore, Student is a reference data type. When new Student() is executed, the reference to created student object is assigned to the varible john. A reference to an object is the address of the object in memory. Now, if you use the varibale john and .(dot), you can access to the student object which john is referring to as below;
john.name = "John Adams";
Type casting means that converting the data type of value to desired data type. Type Casting is divided into two types. One is called Up-Casting, it happens automatically by the JVM. The Other is called Down-Casting, if you want it happens, put (desired data type) before literals or variables.
long money = 300;//300 is int literal and value of 300 is created as int type.
Java is strict on the data type applies. So, variable money shall be assigned a value of long type.
In this case, JVM converted 300 of int type to 300 of long type before the assignment.
Automatic type casting happens to a large datatypes direction from a small data type.
byte --> short --> int --> long --> float --> double)
So, it is called Up-Casting.
Even so float occupies 4 bytes of memory size and long occupies 8 bytes of memory size, but long are automatically cast to float.
float x = 10L;//JVM convert 10 of long type to 10 of float type automatically.
int x = 3 + 3.5 + 4; //compile error
Value of 3.5 is created as a double type and value of 3 and 4 are created as int type. In the arithmetic which int type and larger type than int participates in, every value will converted to the largest data type of values as below;
int x = 3.0 + 3.5 + 4.0;
The result of 3.0 + 3.5 + 4.0 is dobule and can not be assigned to an int type variable x, resulting in a compile error.
float f = 1.1; //compile error
The above code occurs a compile error because you cannot assign double to float. Type casting from large type to small type does not happen automatically.
float f = (float) 1.1;
The above code converts value of double type to value of float type. Forcing data types to be changed using parentheses is called down casting. Let's assume the value assigned to b in the following.
byte b = (byte) 258;
2 is assigned to b. When int converts to byte, front 3 bytes of 4 bytes is lost.
For arithmetic operations involving byte or short values, all values are cast to int type before the operation proceeds.
short s1 = 1; short s2 = 2; short sum = s1 + s2; //compile error
When s1 and s2 participate in an operation, they are all cast as an int type, so the result is an int type value. If you want to avoid compilation errors. cast as shown below;
short sum = (short) (s1 + s2);
다음 예에서 z에 할당되는 값을 예상해 보자.
int x = 10; int y = 4; int z = x / y;
We expect 2.5, but z is assigned 2. Since x and y are both int types, the operation result is also of type int. If you want z to be assigned a value of 2.5, you must change the type of the variable z to double and cast either x or y to a double.
double z = (double) x / y;
If you cast x to a double type, y is automatically cast to the double.

Jack Ross identifies where Hibs could strengthen ahead of January transfer window
Hibees are well stocked for attacking midfielders but could do with more defensive types.
by Ross Pilcher, https://www.dailyrecord.co.uk/authors/ross-pilcher/Jack Ross may look to increase his defensive midfield options during the January transfer window.
The Hibs boss isn’t planning on being overly busy in the transfer market and hopes the performances of the players currently in the building mean it’s just a case of filling gaps in the squad.
One area that may require attention is the middle of the park however, with the Hibees lacking natural holding midfielders since Marvin Bartley and Mark Milligan departed in the summer.
Josh Vela’s arrival under Paul Heckingbottom was meant to address that issue to an extent, but the former Bolton man hasn’t been quoted in any of Ross’ squads since he took control last month.
Swede Melker Hallberg has filled the role against Aberdeen at the weekend in an otherwise attacking midfield that included Scott Allan, Martin Boyle and Stevie Mallan.
But a specialist could be on the New Year shopping list to give his side more balance.
“Our team selection on Saturday was pretty bold because even with Melker in the middle of the park, he’s not a natural sitting midfield player,” Ross explained. “He’s having to learn his trade in that respect.
“We’ve got a lot of forward thinking players within the group but when it clicks, it’s good.
“He’s got the capabilities to play there. He’s still a young man and another that I’ve been really impressed with. He’s a good player.
“He’s intelligent and wants to learn the position. I spoke with him individually and showed him some things. He took them on board on Saturday and did the job really well.
“He fatigued a bit because he missed pre-season.
“At the moment he’s doing that role and I’ve been pleased with him in it.
"It’s just the depth in that position because we don’t have many of those types within the squad.”


11 things you should never say to your bartender, Business Insider - Business Insider Singapore
by Emma Witman, Business Insider US- Bartenders like me are under a lot of stress every night.
- Our job gets even harder when we have to process foolish or uninformed statements and requests from customers.
- Here are 11 things you should never say to your bartender if you want to stay on their good side.
- Visit Business Insider’s homepage for more stories.

There’s the obvious stress that comes with preparing drinks under time pressure for a never-ending stream of customers.
But every night, we also process an untold number of idiotic statements and requests that drive us crazy, even though we politely nod in response to the customers who make them.
I wish I could blame the bad banter on people overdrinking, but frankly, a lot of the weird things that come out of people’s mouths are simply the result of having never worked in the service industry. If you could see things from the bartender’s perspective, you might think twice about asking for “a strong pour” or for your bartender to “surprise” you, for example.
There’s a lot you can say to be a better bar guest, but you can do a favor for bartenders everywhere by simply not saying certain things.
So with that said, consider taking a thoughtful pause before uttering any of these 11 phrases to your bartender.
‘You should smile more.’
This is my No. 1 pet peeve.
 Consider this: Smiling might literally be driving us to drink more after our shift.
Something to think about next time you feel like harassing your bartender to give you a smile.
It’s normal that a lot of bartenders assume a Resting Bartender Face, the focused facial expression we might land on when we’re trying to do the best job possible.
Do you have a huge, giddy smile when you’re filling out spreadsheets, editing an article, drawing blood, mixing tracks, or whatever else your job entails? Probably not. So please – let this one go.  We’re just trying to focus.
‘Do you know how to make an old fashioned?’
While we’re on the topic of sexism, asking a bartender if they know how to make an old fashioned is also a question that’s usually directed at women.
Although, I did once enjoy the smug satisfaction of hearing my male coworker being asked if he knew “how to craft a Manhattan.”
The thing is, an old fashioned is so simple and such a staple that the vast, vast majority of bartenders know how to make one.
Your greater concern should be if the bar has the means to make one. So rather than ask if the bartender knows “how” to make one, ask a variation on, “Do you make old fashioneds here?” or “How do you make your old fashioneds here?”
For me personally, rather than ask, I scan the bar to see if I can spot a bottle of Angostura bitters, easily spotted by its trademark oversized label.
But if the bar clearly doesn’t carry bitters, sweetener, or oranges, maybe just don’t ask in the first place, and grab a beer and a shot instead.
On a similar note, ‘Do you make a good old fashioned?’
You can replace old fashioned here with any kind of classic cocktail, like a mojito, daiquiri or cosmo.
I don’t understand why people ask if we make a good version of any cocktail. Which is why I usually pause to collect myself before slowly, and with a hint of scorn, saying “… Yes.”
What other response could there be?
“No. I guess you should go to another bar,” perhaps.
‘Is this menu item good?’
As a corollary to that, asking if a menu item is “good” is also baffling.
Why would we put it on the menu if it weren’t “good”?
Do you think we want to serve you swill?
‘I’m easy. Make me whatever you want.’
People assume we bartenders love requests to “make me whatever you want.”
And I won’t lie. I used to be game for this challenge.
But eventually, I got world-weary, and now I just want you to please, please, please make up your mind, rather than me having to make it up for you.
Even more flustering is when people don’t want to give any additional clues as to what they might like, when the range of drink possibilities is infinite.

‘What’s your real job?’
“What’s your real job?” is a frequent question directed at working bartenders in a capitalist society, for some odd reason.
I truly want to respond, “What do you mean by ‘real?’ Are we in ‘The Matrix?'”
I’ve deemed that the only appropriate response to this question.
For starters, you may consider bartending a “fake” job, but we’re not getting paid Monopoly money to do it – in fact, bartending is paid far better than my former “real” job as a newspaper reporter. And being automated out of bartending isn’t on the horizon – at least not the near horizon.
Even if for some of us it’s more of a transient role, plenty of us are also career bartenders, or learned more while bartending than in any other roles, as Representative Alexandria Ocasio-Cortez has attested herself.
‘This drink is horrible.’
Telling me a drink is “horrible” is a statement of opinion, not fact.
Even better, if you adjust your wording accordingly, you’ll get a better outcome.
Alright, fine. I guess there’s a chance we did indeed mess up your drink, but it’s far more likely that the drink was technically made correctly and your expectations simply didn’t meet reality.
The great thing is, there’s usually an easy fix or replacement cocktail we’ll have in mind if you use your words and tell us what you didn’t like.
‘What bars do you like to go to around here?’
This is either a silly ploy to track me down after work or a desire to feel special because you – correctly – assume that I never divulge this information.
You probably don’t want to go to the bars that bartenders go to anyway. They are places where no one is required to smile and Miller High Life is the most preferred beverage.
‘Wow. That’s a lot of ice for a $13 drink.’

If you’re going to have the audacity to complain about a $13 cocktail that takes several steps to make before you’ve even had one sip, please, spare us both. Get the $2 lager instead.
‘Your bourbon selection sucks.’
I hear this complaint frequently as a bartender in an ABC state. That means my state strictly regulates the sales of all hard liquor. As a consequence, high-demand bourbons aren’t allocated in large numbers here.
Please complain to our state legislators, rather than throw the negativity at us.
‘Make it strong’ or ‘Don’t be shy with your pour.’
There are so many things I hate about requests to make a drink strong, even when made in a jovial manner.
For starters, it’s the icky entitlement: If you want more booze in your drink, pay for a double.
I hate feeling like someone is trying to badger me into giving them more just because they applied some pressure, especially when other guests are within earshot.
It won’t work. In fact, it might even backfire when I feel less inclined to pour that shot all the way to the tension point of the jigger, or count a little more quickly than I usually do if I’m pouring without one.


Ireland - Profile
Facts
- The North Atlantic island of Ireland is made up of two political units, the independent Republic of Ireland, also known as Eire, and the smaller region of Northern Ireland, which is part of the United Kingdom.
- Ireland has a coastline of nearly 3000 miles with many deep and sheltered bays. Described by some sailing authors as one of the finest cruising grounds in the world, the only missing element to put Ireland at the top of the table is better weather. At least this is more than made up for by a profusion of perfectly sheltered anchorages.
- Ireland's three coasts are very different and in their variety they cater for every requirement. The east coast is the most easily accessible for yachts coming from the United Kingdom, but Ireland's real beauty lies on its southern and western coasts. The most popular cruising area is between Cork and the Dingle Peninsula with an abundance of snug harbours and picturesque anchorages.
- The wilder west coast is more exposed and the distances between sheltered harbours are greater. Some 200 islands lie scattered off the west coast and only a handful are inhabited. While the east and southwestern coasts have a sizeable local boating population and also attract a number of cruising yachts, the west of Ireland is less frequented.
- Repair facilities for yachts range from excellent in such major yachting centres as Cork Harbour to virtually non-existent in some of the smaller ports. The facilities at Crosshaven are possibly the best in Ireland and a whole range of repair services is available. Further east, repair facilities are also available at Youghal and Waterford.
- Provisioning in all ports on the east and south coast is good and there are several marinas scattered about. As one moves west, supplies become scarcer and the boat should be well provisioned with food, fuel and water.
- A useful source of help are the many yacht clubs dotted about the coasts, the most famous among them being the Royal Cork Yacht Club in Crosshaven, founded in 1720 and considered the oldest yacht club in the world. Most yacht clubs have moorings for visitors who are generally made welcome everywhere.
Weather
Ireland has a mild humid climate influenced by the Gulf Stream. Rainfall is very heavy all year round on the western coast. Strong winds and gales are most frequently from the SW and are very common in winter. The weather is generally very changeable. The prevailing winds are westerly. Higher seas are encountered off the west coast than in any other neighbouring area.

It’s no revelation that retro/vintage style is popular these days. Cars, clothes even computer games.
Geometry Wars, Gravity Crash, Pew-Pew and many more share a certain pattern, simple vector graphics and arcade style.
Orbital is a peculiar game. If Missile Command, Arcanoid and Puzzle Bobble shared a night of passion – then their offspring could be Orbital
I highly recommend it for anyone wanting to “waste” some time.

I'm A Celebrity viewers concerned for Jacqueline Jossa after she's picked for Bushtucker trial
She will try and win meals for camp in Snake Hotel
by Rebecca CarterViewers of I'm A Celebrity have expressed concerns for Jacqueline Jossa as she was picked to do a Bushtucker trial.
On Thursday night's episode, the former EastEnders actress was voted by the public to do tonight's trial, Snake Hotel.
And she didn't take it well when hosts Ant McPartlin and Dec Donnelly revealed the news to camp.

After it was announced she will be doing the trial, Jacqueline shouted: "No! No!"
She continued: "I'm panicking again. I want to do it with someone else though.
"Ian it could have been the two of us and I feel like I could do it if you were there."
Viewers have already voiced their worry for Jacqueline and shared their thoughts on Twitter.
One person said: "I'm already feeling worried for Jacqueline, hope she does well."
Another wrote: "The fact Britain voted for Jacqueline to do the trial after how much she genuinely struggled last time and the reaction she had, just shows how sick the British public can be!!!"
A third added: "I feel for Jacqueline getting that trial tomorrow hope she gets through it."
Others admitted they had voted for her to do the trial after she refused to participate in a challenge last night.
The campmates had to pick two stars to join newbies Andy Whyment and Cliff Parisi as Outlaws in the Jungle Jailhouse.
However, Jacqueline and Nadine Coyle admitted they didn't want to take part and viewers weren't happy.
One person said: "Don’t think Jacqueline and Nadine refusing is gonna do them any good is it one of them is gonna get voted."
Another wrote: "Just used all my votes for Jaqueline & Nadine.

Redux Essentials, Part 5: Async Logic and Data FetchingWhat You'll Learn
- How to use the Redux "thunk" middleware for async logic
- Patterns for handling async request state
-
How to use the Redux Toolkit
createAsyncThunk
API to simplify async calls
Prerequisites
- Familiarity with using AJAX requests to fetch and update data from a server
#
IntroductionIn Part 4: Using Redux Data, we saw how to use multiple pieces of data from the Redux store inside of React components, customize the contents of action objects before they're dispatched, and handle more complex update logic in our reducers.
So far, all the data we've worked with has been directly inside of our React client application. However, most real applications need to work with data from a server, by making HTTP API calls to fetch and save items.
In this section, we'll convert our social media app to fetch the posts and users data from an API, and add new posts by saving them to the API.
#
Example REST API and Client
To keep the example project isolated but realistic,
the initial project setup already included a fake
in-memory REST API for our data (configured using
the Mirage.js mock API tool). The API uses /fakeApi
as the base URL
for the endpoints, and supports the typical
GET/POST/PUT/DELETE
HTTP methods for
/fakeApi/posts
,
/fakeApi/users
, and
fakeApi/notifications
. It's defined
in src/api/server.js
.
The project also includes a small HTTP API client
object that exposes client.get()
and
client.post()
methods, similar to popular
HTTP libraries like axios
. It's
defined in src/api/client.js
.
We'll use the client
object to make
HTTP calls to our in-memory fake REST API for this
section.
Also, the mock server has been set up to reuse the
same random seed each time the page is loaded, so that
it will generate the same list of fake users and fake
posts. If you want to reset that, delete the
'randomTimestampSeed'
value in
your browser's Local Storage and reload the page,
or you can turn that off by editing
src/api/server.js
and setting
useSeededRNG
to false
.
info
As a reminder, the code examples focus on the key
concepts and changes for each section. See the
CodeSandbox projects and the
tutorial-steps
branch in the
project repo
for the complete changes in the application.
#
Thunks and Async Logic#
Using Middleware to Enable Async LogicBy itself, a Redux store doesn't know anything about async logic. It only knows how to synchronously dispatch actions, update the state by calling the root reducer function, and notify the UI that something has changed. Any asynchronicity has to happen outside the store.
But, what if you want to have async logic interact with the store by dispatching or checking the current store state? That's where Redux middleware come in. They extend the store, and allow you to:
- Execute extra logic when any action is dispatched (such as logging the action and state)
- Pause, modify, delay, replace, or halt dispatched actions
-
Write extra code that has access to
dispatch
andgetState
-
Teach
dispatch
how to accept other values besides plain action objects, such as functions and promises, by intercepting them and dispatching real action objects instead
The most common reason to use middleware is to allow different kinds of async logic to interact with the store. This allows you to write code that can dispatch actions and check the store state, while keeping that logic separate from your UI.
There are many kinds of async middleware for Redux,
and each lets you write your logic using different
syntax. The most common async middleware is
redux-thunk
, which lets you write plain functions that may
contain async logic directly. Redux Toolkit's
configureStore
function
automatically sets up the thunk middleware by
default, and
we recommend using thunks as the standard approach
for writing async logic with Redux.
Earlier, we saw what the synchronous data flow for Redux looks like. When we introduce asynchronous logic, we add an extra step where middleware can run logic like AJAX requests, then dispatch actions. That makes the async data flow look like this:
#
Thunk Functions
Once the thunk middleware has been added to the Redux
store, it allows you to pass
thunk functions directly to
store.dispatch
. A thunk function will
always be called with
(dispatch, getState)
as its arguments,
and you can use them inside the thunk as needed.
Thunks typically dispatch plain actions using action
creators, like dispatch(increment())
:
For consistency with dispatching normal action objects, we typically write these as thunk action creators, which return the thunk function. These action creators can take arguments that can be used inside the thunk.
Thunks are typically written in "slice"
files. createSlice
itself does not have
any special support for defining thunks, so you should
write them as separate functions in the same slice
file. That way, they have access to the plain action
creators for that slice, and it's easy to find
where the thunk lives.
#
Writing Async Thunks
Thunks may have async logic inside of them, such as
setTimeout
, Promise
s, and
async/await
. This makes them a good place
to put AJAX calls to a server API.
Data fetching logic for Redux typically follows a predictable pattern:
- A "start" action is dispatched before the request, to indicate that the request is in progress. This may be used to track loading state to allow skipping duplicate requests or show loading indicators in the UI.
- The async request is made
- Depending on the request result, the async logic dispatches either a "success" action containing the result data, or a "failure" action containing error details. The reducer logic clears the loading state in both cases, and either processes the result data from the success case, or stores the error value for potential display.
These steps are not required, but are commonly used. (If all you care about is a successful result, you can just dispatch a single "success" action when the request finishes, and skip the "start" and "failure" actions.)
Redux Toolkit provides a
createAsyncThunk
API to implement the
creation and dispatching of these actions, and
we'll look at how to use it shortly.
Detailed Explanation: Dispatching Request Status
Actions in Thunks
If we were to write out the code for a typical async thunk by hand, it might look like this:
However, writing code using this approach is tedious. Each separate type of request needs repeated similar implementation:
- Unique action types need to be defined for the three different cases
- Each of those action types usually has a corresponding action creator function
- A thunk has to be written that dispatches the correct actions in the right sequence
createAsyncThunk
abstracts this pattern
by generating the action types and action creators,
and generating a thunk that dispatches those actions
automatically. You provide a callback function that
makes the async call and returns a Promise with the
result.
#
Loading Posts
So far, our postsSlice
has used some
hardcoded sample data as its initial state. We're
going to switch that to start with an empty array of
posts instead, and then fetch a list of posts from the
server.
In order to do that, we're going to have to
change the structure of the state in our
postsSlice
, so that we can keep track of
the current state of the API request.
#
Extracting Posts Selectors
Right now, the postsSlice
state is a
single array of posts
. We need to change
that to be an object that has the
posts
array, plus the loading state
fields.
Meanwhile, the UI components like
<PostsList>
are trying to read
posts from state.posts
in their
useSelector
hooks, assuming that that
field is an array. We need to change those locations
also to match the new data.
It would be nice if we didn't have to keep rewriting our components every time we made a change to the data format in our reducers. One way to avoid this is to define reusable selector functions in the slice files, and have the components use those selectors to extract the data they need instead of repeating the selector logic in each component. That way, if we do change our state structure again, we only need to update the code in the slice file.
The <PostsList>
component needs to
read a list of all the posts, and the
<SinglePostPage>
and
<EditPostForm>
components need to
look up a single post by its ID. Let's export two
small selector functions from
postsSlice.js
to cover those cases:
Note that the state
parameter for these
selector functions is the root Redux state object, as
it was for the inlined anonymous selectors we wrote
directly inside of useSelector
.
We can then use them in the components:
It's often a good idea to encapsulate data lookups by writing reusable selectors. You can also create "memoized" selectors that can help improve performance, which we'll look at in a later part of this tutorial.
But, like any abstraction, it's not something you should do all the time, everywhere. Writing selectors means more code to understand and maintain. Don't feel like you need to write selectors for every single field of your state. Try starting without any selectors, and add some later when you find yourself looking up the same values in many parts of your application code.
#
Loading State for RequestsWhen we make an API call, we can view its progress as a small state machine that can be in one of four possible states:
- The request hasn't started yet
- The request is in progress
- The request succeeded, and we now have the data we need
- The request failed, and there's probably an error message
We could track that information using some
booleans, like isLoading: true
, but
it's better to track these states as a single
enum value. A good pattern for this is to have a state
section that looks like:
These fields would exist alongside whatever actual
data is being stored. These specific string state
names aren't required - feel free to use other
names if you want, like
'pending'
instead of
'loading'
, or
'complete'
instead of
'succeeded'
.
We can use this information to decide what to show in our UI as the request progresses, and also add logic in our reducers to prevent cases like loading data twice.
Let's update our postsSlice
to use
this pattern to track loading state for a "fetch
posts" request. We'll switch our state from
being an array of posts by itself, to look like
{posts, status, error}
. We'll also
remove the old sample post entries from our initial
state. As part of this change, we also need to change
any uses of state
as an array to be
state.posts
instead, because the array is
now one level deeper:
Yes, this does mean that we now have a nested
object path that looks like
state.posts.posts
, which is somewhat
repetitive and silly :) We could change the
nested array name to be items
or
data
or something if we wanted to avoid
that, but we'll leave it as-is for now.
createAsyncThunk
#
Fetching Data with
Redux Toolkit's createAsyncThunk
API
generates thunks that automatically dispatch those
"start/success/failure" actions for you.
Let's start by adding a thunk that will make an
AJAX call to retrieve a list of posts. We'll
import the client
utility from the
src/api
folder, and use that to make a
request to '/fakeApi/posts'
.
createAsyncThunk
accepts two arguments:
- A string that will be used as the prefix for the generated action types
-
A "payload creator" callback function that
should return a
Promise
containing some data, or a rejectedPromise
with an error
The payload creator will usually make an AJAX call of
some kind, and can either return the
Promise
from the AJAX call directly, or
extract some data from the API response and return
that. We typically write this using the JS
async/await
syntax, which lets us write
functions that use Promise
s while using
standard try/catch
logic instead of
somePromise.then()
chains.
In this case, we pass in
'posts/fetchPosts'
as the
action type prefix. Our payload creation callback
waits for the API call to return a response. The
response object looks like {posts: []}
,
and we want our dispatched Redux action to have a
payload that is just the array of posts. So,
we extract response.posts
, and return
that from the callback.
If we try calling dispatch(fetchPosts())
,
the fetchPosts
thunk will first dispatch
an action type of
'posts/fetchPosts/pending'
:
We can listen for this action in our reducer and mark
the request status as
'loading'
.
Once the Promise
resolves, the
fetchPosts
thunk takes the
response.posts
array we returned from the
callback, and dispatches a
'posts/fetchPosts/fulfilled'
action containing the posts array as
action.payload
:
#
Dispatching Thunks from Components
So, let's update our
<PostsList>
component to actually
fetch this data automatically for us.
We'll import the fetchPosts
thunk
into the component. Like all of our other action
creators, we have to dispatch it, so we'll also
need to add the useDispatch
hook. Since
we want to fetch this data when
<PostsList>
mounts, we need to
import the React useEffect
hook:
It's important that we only try to fetch the list
of posts once. If we do it every time the
<PostsList>
component renders, or
is re-created because we've switched between
views, we might end up fetching the posts several
times. We can use the posts.status
enum
to help decide if we need to actually start fetching,
by selecting that into the component and only starting
the fetch if the status is
'idle'
.
#
Reducers and Loading Actions
Next up, we need to handle both these actions in our
reducers. This requires a bit deeper look at the
createSlice
API we've been using.
We've already seen that
createSlice
will generate an action
creator for every reducer function we define in the
reducers
field, and that the generated
action types include the name of the slice, like:
However, there are times when a slice reducer needs to
respond to other actions that weren't
defined as part of this slice's
reducers
field. We can do that using the
slice extraReducers
field instead.
Detailed Explanation: Adding Extra Reducers to
Slices
The keys in the extraReducers
object
should be Redux action type strings, like
'counter/increment'
. We
could write those by hand ourselves,
although we'd have to quote the keys if they
contain any characters like '/':
However, action creators generated by Redux Toolkit
automatically return their action type string if you
call actionCreator.toString()
. This
means we can pass them as ES6 object literal
computed properties, and the action types will
become the keys of the object:
This works for the extraReducers
field:
We can also add extra reducers by using the
"builder callback" syntax for
extraReducers
. If we pass a function
for extraReducers
instead of an object,
we can use the builder
parameter to add
individual cases. The
builder.addCase()
function takes either
a plain string action type to listen for, or a Redux
Toolkit action creator:
If you're using TypeScript, you should use the
builder callback form of extraReducers
.
In this case, we need to listen for the
"pending" and "fulfilled" action
types dispatched by our fetchPosts
thunk.
Those action creators are attached to our actual
fetchPost
function, and we can pass those
to extraReducers
to listen for those
actions:
We'll handle all three action types that could be
dispatched by the thunk, based on the
Promise
we returned:
-
When the request starts, we'll set the
status
enum to'loading'
-
If the request succeeds, we mark the
status
as'succeeded'
, and add the fetched posts tostate.posts
-
If the request fails, we'll mark the
status
as'failed'
, and save any error message into the state so we can display it
#
Displaying Loading State
Our <PostsList>
component is
already checking for any updates to the posts that are
stored in Redux, and rerendering itself any time that
list changes. So, if we refresh the page, we should
see a random set of posts from our fake API show up on
screen:
The fake API we're using returns data immediately. However, a real API call will probably take some time to return a response. It's usually a good idea to show some kind of "loading..." indicator in the UI so the user knows we're waiting for data.
We can update our <PostsList>
to
show a different bit of UI based on the
state.posts.status
enum: a spinner if
we're loading, an error message if it failed, or
the actual posts list if we have the data. The result
might look like this:
But, the fake API call is still returning almost
immediately, so we can barely see the loading spinner
right now. If you want to force the fake API call to
take longer, you can open up
api/server.js
, and uncomment this line:
Uncommenting that line will force the fake API to wait 2 seconds before responding. Feel free to turn that on and off as we go if you want to see how the UI shows our loading spinner.
#
Loading UsersWe're now fetching and displaying our list of posts. But, if we look at the posts, there's a problem: they all now say "Unknown author" as the authors:
This is because the post entries are being randomly generated by the fake API server, which also randomly generates a set of fake users every time we reload the page. We need to update our users slice to fetch those users when the application starts.
Like last time, we'll create another async thunk
to get the users from the API and return them, then
handle the fulfilled
action in the
extraReducers
slice field. We'll
skip worrying about loading state for now:
We only need to fetch the list of users once, and we
want to do it right when the application starts. We
can do that in our index.js
file, and
directly dispatch the fetchUsers
thunk
because we have the store
right there:
Now, each of the posts should be showing a username
again, and we should also have that same list of users
shown in the "Author" dropdown in our
<AddPostForm>
.
#
Adding New Posts
We have one more step for this section. When we add a
new post from the <AddPostForm>
,
that post is only getting added to the Redux store
inside our app. We need to actually make an API call
that will create the new post entry in our fake API
server instead, so that it's "saved".
(Since this is a fake API, the new post won't
persist if we reload the page, but if we had a real
backend server it would be available next time we
reload.)
#
Sending Data with Thunks
We can use createAsyncThunk
to help with
sending data, not just fetching it. We'll create
a thunk that accepts the values from our
<AddPostForm>
as an argument, and
makes an HTTP POST call to the fake API to save the
data.
In the process, we're going to change how we work
with the new post object in our reducers. Currently,
our postsSlice
is creating a new post
object in the prepare
callback for
postAdded
, and generating a new unique ID
for that post. In most apps that save data to a
server, the server will take care of generating unique
IDs and filling out any extra fields, and will usually
return the completed data in its response. So, we can
send a request body like
{ title, content, user: userId }
to the
server, and then take the complete post object it
sends back and add it to our
postsSlice
state.
#
Checking Thunk Results in Components
Finally, we'll update
<AddPostForm>
to dispatch the
addNewPost
thunk instead of the old
postAdded
action. Since this is another
API call to the server, it will take some time and
could fail. The
addNewPost()
thunk will automatically
dispatch its
pending/fulfilled/rejected
actions to the
Redux store, which we're already handling. We
could track the request status in
postsSlice
using a second loading enum if
we wanted to, but for this example let's keep the
loading state tracking limited to the component.
It would be good if we can at least disable the "Save Post" button while we're waiting for the request, so the user can't accidentally try to save a post twice. If the request fails, we might also want to show an error message here in the form, or perhaps just log it to the console.
We can have our component logic wait for the async thunk to finish, and check the result when it's done:
We can add a loading status enum field as a React
useState
hook, similar to how we're
tracking loading state in postsSlice
for
fetching posts. In this case, we just want to know if
the request is in progress or not.
When we call dispatch(addNewPost())
, the
async thunk returns a Promise
from
dispatch
. We can await
that
promise here to know when the thunk has finished its
request. But, we don't yet know if that request
succeeded or failed.
createAsyncThunk
handles any errors
internally, so that we don't see any messages
about "rejected Promises" in our logs. It
then returns the final action it dispatched: either
the fulfilled
action if it succeeded, or
the rejected
action if it failed. Redux
Toolkit has a utility function called
unwrapResult
that will return either the
actual action.payload
value from a
fulfilled
action, or throw an error if
it's the rejected
action. This lets
us handle success and failure in the component using
normal try/catch
logic. So, we'll
clear out the input fields to reset the form if the
post was successfully created, and log the error to
the console if it failed.
If you want to see what happens when the
addNewPost
API call fails, try creating a
new post where the "Content" field only has
the word "error" (without quotes). The
server will see that and send back a failed response,
so you should see a message logged to the console.
#
What You've LearnedAsync logic and data fetching are always a complex topic. As you've seen, Redux Toolkit includes some tools to automate the typical Redux data fetching patterns.
Here's what our app looks like now that we're fetching data from that fake API:
As a reminder, here's what we covered in this section:
Summary
-
You can write reusable "selector"
functions to encapsulate reading values from
the Redux state
-
Selectors are functions that get the Redux
state
as an argument, and return some data
-
Selectors are functions that get the Redux
-
Redux uses plugins called
"middleware" to enable async
logic
-
The standard async middleware is called
redux-thunk
, which is included in Redux Toolkit -
Thunk functions receive
dispatch
andgetState
as arguments, and can use those as part of async logic
-
The standard async middleware is called
-
You can dispatch additional actions to help
track the loading status of an API
call
- The typical pattern is dispatching a "pending" action before the call, then either a "success" containing the data or a "failure" action containing the error
-
Loading state should usually be stored as an
enum, like
'idle' | 'loading' | 'succeeded' | 'failed'
-
Redux Toolkit has a
createAsyncThunk
API that dispatches these actions for you-
createAsyncThunk
accepts a "payload creator" callback that should return aPromise
, and generatespending/fulfilled/rejected
action types automatically -
Generated action creators like
fetchPosts
dispatch those actions based on thePromise
you return -
You can listen for these action types in
createSlice
using theextraReducers
field, and update the state in reducers based on those actions. -
Action creators can be used to automatically
fill in the keys of the
extraReducers
object so the slice knows what actions to listen for.
-

What's Next?We've got one more set of topics to cover for this tutorial. In Part 6: Performance and Normalizing Data, we'll look at how Redux usage affects React performance, and some ways we can optimize our application for improved performance.

Downloading KDE Frameworks
The easiest way to get the KDE Frameworks packages is to use a
single wget to fetch
them all at once:
url=http://download.kde.org/stable/frameworks/5.73/
wget -r -nH -nd -A '*.xz' -np $url
The options used here are:
-r recurse through child directories
-nH disable generation of host-prefixed directories
-nd do not create a hierarchy of directories
-A '*.xz' just get the *.xz files
-np don't get parent directories
Setting Package Order
The order of building files is important due to internal
dependencies. Create the list of files in the proper order as
follows:

In the above list, notice that some files have been commented out
with a hash (#) character. The extra-cmake-modules entry has been
commented out because it was built earlier in the Introduction to
KDE. The icon packages are covered separately at breeze-icons-5.73.0 and oxygen-icons5-5.73.0. The
modemmanager-qt package may be built if its optional dependency has
been installed. The prison package (bar code reader) may be built
if the required external libraries are installed. The kdewebkit may
be built if the external package QtWebkit
has been built.
Installation of KDE Frameworks
Note
When installing multiple packages in a script, the installation
needs to be done as the root user. There are three general
options that can be used to do this:
-
Run the entire script as the root user (not recommended).
-
Use the sudo
command from the Sudo-1.9.2
package.
-
Use su -c "command
arguments" (quotes required) which will ask
for the root password for every iteration of the loop.
One way to handle this situation is to create a short
bash function that
automatically selects the appropriate method. Once the command is
set in the environment, it does not need to be set again.
as_root()
{
if [ $EUID = 0 ]; then $*
elif [ -x /usr/bin/sudo ]; then sudo $*
else su -c \\"$*\\"
fi
}
export -f as_root
Caution
If installing in /opt
and there is
an existing /opt/kf5 either as a regular directory or a symbolic
link, it should be reinitialized (as root
):
mv -v /opt/kf5 /opt/kf5.old &&
install -v -dm755 $KF5_PREFIX/{etc,share} &&
ln -sfv /etc/dbus-1 $KF5_PREFIX/etc &&
ln -sfv /usr/share/dbus-1 $KF5_PREFIX/share
First, start a subshell that will exit on error:
bash -e
Install all of the packages by running the following commands:
while read -r line; do
# Get the file name, ignoring comments and blank lines
if $(echo $line | grep -E -q '^ *$|^#' ); then continue; fi
file=$(echo $line | cut -d" " -f2)
pkg=$(echo $file|sed 's|^.*/||') # Remove directory
packagedir=$(echo $pkg|sed 's|\.tar.*||') # Package directory
name=$(echo $pkg|sed 's|-5.*$||') # Isolate package name
tar -xf $file

Note
Any modules that have been omitted can be installed later by
using the same mkdir build; cd
build; cmake; make; make install procedure as
above.
Sometimes the installation paths are hardcoded into installed
files. If the installed directory is not /usr, rename the directory
and create a symlink:
mv -v /opt/kf5 /opt/kf5-5.73.0
ln -sfvn kf5-5.73.0 /opt/kf5
Command Explanations

Thousands gather ahead of rare Japan imperial parade
TOKYO: Thousands of people gathered in Tokyo on Sunday (Nov 10) ahead of a rare open-top car parade featuring newly enthroned Emperor Naruhito and Empress Masako, with heavy security in place for the event.
The motorcade scheduled for later in the afternoon is one of the final public events associated with Naruhito's assumption of the throne following his father Akihito's abdication earlier this year.
The royal couple will be driven around 4.6km through central Tokyo, with tens of thousands expected to line the route.
The couple's first parade since their marriage in 1993 was originally scheduled for Oct 22 as part of a series of events marking the official proclamation of Emperor Naruhito's enthronement.
But the government rescheduled the parade after nearly 80 people were killed in Typhoon Hagibis, which slammed into Japan in mid-October, causing widespread damage.
Hours before the scheduled 3pm (2pm Singapore time) start of the parade, long queues formed at dozens of security checkpoints, with eager spectators waiting to secure seats to watch the motorcade, which will feature around 50 vehicles in total.
"I'm looking forward to see the dress Empress Masako will wear," Hiroko Kikuta, in her 60s, told AFP.
"This will be my last chance to see an imperial parade," added Yukari Oshita, also in her 60s, as she waited near the Imperial Palace.
"The Emperor is a few years younger than me but belongs to the same generation," she said.
"And Empress Masako is someone who can be a role model for modern women with full-time jobs," she said.
Born into a diplomatic family and educated at Harvard, Masako left behind a promising diplomatic career to marry into the royal family.
She has struggled to adjust to cloistered royal life, suffering an adjustment disorder that led to a scaling back of her public appearances.
But she has appeared confident during the events marking Naruhito's enthronement.
She won plaudits for her assured performance when US President Donald Trump became the first foreign leader to meet the new emperor, winning praise in particular for her ability to converse in fluent English.
Naruhito, 59, officially succeeded his father in May, but a series of ceremonies and rites celebrating his enthronement are being held last month, this month and later this year. The official enthronement ceremony was held last month.
The parade comes a day after a national festival to celebrate the enthronement with dancers and pop stars offering performances.


Mum smacks daughter, 8, with a belt because she didn't do her homework 'properly'
The woman, originally from China, defended her actions by saying it was acceptable in her own country
by Neil MurphyA Chinese mother has admitted to smacking her eight-year-old daughter with a belt because she didn't do her homework 'properly'.
The unnamed woman, who lives in Queensland, Australia, defended her actions by saying that the practice was acceptable in her home country.
She carried out the cruel punishment because her daughter was not completing her homework assignments correctly.
The girl has since been taken out of her care after child protection services became involved, reports the Queensland Times .
The mother pleaded guilty in Ipswich Magistrates Court to assaulting a child when armed with an instrument, causing bodily harm.
Defence lawyer Matthew Fairclough told the court that the child alleged she had been treated inappropriately.
"Child Safety took a view of the matter that the children should not remain in her care," he said.
"Her husband is here with her (in the courtroom). It has proven to be quite troubling for the family.
"It has been a significant wake-up call for both parents."
Mr Fairclough said the mother wanted to resume her role as a parent and has taken part in a parenting program.
Magistrate Virginia Sturgess said parents should not beat their children under any circumstances, branding the practice "unacceptable".
The mother was sentenced to a supervised nine-month probation order.

onAs a recovering full-stack developer who went the specialised front-end route a few years ago, the one aspect I have always hated about building any feature-rich web application is authentication. Thankfully a lot of convenient options have popped up over the last couple of years like Auth0 [https://auth0.com/].

onToday I'd like to introduce you to Aurelia community member Keith Katsma. Keith has been a software engineer and architect for almost 20 years. After a lot of work with ASP back in the early 2000s, he veered off into the design and development of service oriented architectures. However, a couple years ago he was reintroduced to UI development through AngularJS, and has recently spent a lot of time getting to know some of the latest JavaScript frameworks - Angular 2, React, and Aurelia. Of particular note, Keith has been doing some great work to improve the Aurelia experience for ASP.NET developers. I'll let him tell you about it in his own words...

onIn 2015 we first announced Aurelia, a modern frontend framework with an emphasis on convention over configuration, web standards and productivity. Aurelia provides the core capabilities you need to build apps, such as templating, binding, an application model, routing and dependency injection. We've also created tons of plugins for http, i18n, validation, etc. and partnered with various community groups to build even more. However, there's always been something missing. Today we're introducing Aurelia UX [https://github.com/aurelia/ux], a completely free, open source user experience framework with higher-level capabilities, designed to bring simplicity and elegance to building cross-device, rich experiences.
Posted by October 25, 2016
onToday, I'm happy to introduce to you another Aurelia community group that's built at least a dozen amazing plugins for our community. Read on to learn more...

Adam's Rib (1949)
Grade: 66
"Adam's Rib" is a comedy starring Spencer Tracy and Katherine Hepburn, one of many films that they made together. The film is well cast and well directed, with a fairly good script. The script does resort to petty bickering, and some of the characters should have been made more sympathetic. The script also makes unnecessary points about gender equality.
The story has Tracy and Hepburn as a married couple. Tracy is a Prosecutor, Hepburn an attorney, and they end up on opposite sides of an attempted murder trial. Judy Holliday is the not-too-bright defendant, having shot her negligent husband Tom Ewell after catching him with floosie Jean Hagen. Hepburn's defense relies on the dubious assumption that a husband would be found innocent of such a shooting, and thus convicting Holliday would be a sexist double standard. The Tracy/Hepburn marriage is strained by Hepburn's zealous defense, and also by obnoxious composer David Wayne, who has the hots for Hepburn.
This comedy has two love triangles, Holliday-Ewell-Hagen and Tracy-Hepburn-Wayne. One problem is that all members of the first triangle are unsympathetic, and that justice would be served by locking them all indefinitely in the same jail cell. The second love triangle is more interesting, especially since Hepburn subtly encourages Wayne's behavior. Movie audiences at the time may have taken a pool as to when Spencer would finally punch Wayne. He does so, at about the ninety minute mark, and certainly no jury would convict him of assault.
The point being made by the Ruth Gordon/Garson Kanin script is that there is little difference between the sexes. During the trial, Hepburn puts three women on the stand. They have no relevance to the case, except that they have all succeeded in "masculine" fields. Hepburn makes a circus of the trial, enraging Tracy. Tracy is clearly the more sympathetic of the protagonists.
The basic story is good, and served as a premise for an "Adam's Rib" television series in 1973. The script received an Oscar nomination, and the New York Film Critics Circle awarded Judy Holliday their Best Actress award.

This site so far does not teach GLSL just like it does not teach JavaScript. Those are really large topics. If you want to learn GLSL consider checking out these articles as a starting place.
If you already know GLSL then here are a few tips for debugging.
When I'm making a new GLSL shader and nothing appears generally the first thing I do is change the fragment shader to return a solid color. For example at the very bottom of the shader I might put
void main() { ... gl_FragColor = vec4(1, 0, 0, 1); // red }
If I see the object I was trying to draw then I know the issue is related to my fragment shader. It could be anything like bad textures, uninitialized uniforms, uniforms with the wrong values but at least I have a direction to look.
To test some of those I might start trying to draw some of the inputs. For example if I'm using normals in the fragment shader then I might add
gl_FragColor = vec4(vNormal * 0.5 + 0.5, 1);
Normals go from -1 to +1 so by multiplying by 0.5 and adding 0.5 we get values that go from 0.0 to 1.0 which makes them useful for colors.
Try this with some things you know work and you'll start getting an idea of what normals normally look like. If your normals don't look normal then you have some clue where to look. If you're manipulating normals in the fragments shader you can use the same technique to draw the result of that manipulation.
Similarly if we're using textures there will be texture coordinates and we can draw them with something like
gl_FragColor = vec4(fract(vUv), 0, 1);
The fract
is there in case we're using texture coordinates that go outside
the 0 to 1 range. This is common if texture.repeat
is set to something greater
than 1.
You can do similar things for all values in your fragment shader. Figure out
what their range is likely to be, add some code to set gl_FragColor
with
that range scaled to 0.0 to 1.0
To check textures try a CanvasTexture
or a DataTexture
that you
know works.
Conversely, if after setting gl_FragColor
to red I still see nothing
then I have a hint my issue might be in the direction of the things
related to the vertex shader. Some matrices might be wrong or my
attributes might have bad data or be setup incorrectly.
I'd first look at the matrices. I might put a breakpoint right after
my call to renderer.render(scene, camera)
and then start expanding
things in the inspector. Is the camera's world matrix and projection
matrix at least not full of NaN
s? Expanding the scene and looking
at its children
I'd check that the world matrices look reasonable (no NaN
s)
and last 4 values of each matrix look reasonable for my scene. If I
expect my scene to be 50x50x50 units and some matrix shows 552352623.123
clearly something is wrong there.
Just like we did for the fragment shader we can also draw values from the
vertex shader by passing them to the fragment shader. Declare a varying
in both and pass the value you're not sure is correct. In fact if my
shader use using normals I'll change the fragment shader to display them
like is mentioned above and then just set vNormal
to the value I want
to display but scaled so the values go from 0.0 to 1.0. I then look at the
results and see if they fit my expectations.
Another good thing to do is use a simpler shader. Can you draw your data
with MeshBasicMaterial
? If you can then try it and make sure it shows
up as expected.
If not what's the simplest vertex shader that will let you visualize your geometry? Usually it's as simple as
gl_Position = projection * modelView * vec4(position.xyz, 1);
If that works start adding in your changes a little at a time.
Yet another thing you can do is use the Shader Editor extension for Chrome or similar for other browsers. It's a great way to look at how other shaders are working. It's also good as you can make some of the changes suggested above live while the code is running.


I am a Brazilian product designer, based in the Netherlands. Currently designings screens to make bilingual education more approachable at Be Education.
My mom My peers say I'm a passionate and empathic designer, captivated by education and accessibility in technology. Buzzwords apart, I self entitle as a “jack of all trades”, so no problem is too big or too broad that I can’t solve.
Btw, as a full-time nerd, I’d love to talk about anything tech and sci-fi related 🤖
I'm most confident with web design, user research, design thinking, interface design, juggling with three balls, prototyping, interaction design, Figma and Adobe XD.
I have good knowledge (and some professional experience) on web accessibiltiy, Arduinos, video editing, knowing how volcanos are formed 🌋, and UX writing.
Knowing how crucial the communication between designers and developers is, I try to keep in touch with the latest coding trends. And currently I’m learning how to write React ⚛ (I mean the JavaScript library, not actually how to write the word "react". I'm sure you got it, just making sure...)
Also, as a UX Designer, I know pretty much every prototyping tool you throw at me. If you find me a new one, I'll treat you to some coffee. Go ahead, take the challenge 😉
Here are some things I've done in the past. They aren't listed in any specific order, so feel free to randomly browse through them.
You can usually find me playing games at home or running around The Hague. There are easier (and less tiring) ways to get in touch with me, though:


Install on Astroberry RaspberryPi¶
I strongly recommend using the actual astroberry server https://www.astroberry.io if you would like to use KSTars/EKOS and MountWizzard4 on a Raspi (3 or 4).
Under https://github.com/mworion/MountWizzard4/tree/master/support you will find the necessary scripts to install MW4 directly under astroberry. Please download the corresponding ZIP archive (Astroberry_Scripts.zip), make a working directory on astroberry server, extract the archive there and run the install script.
For starting MW4, please start the run script. Basically that’s all to do.
Hint
Actually astroberry is supported from MW4 version 2.1.3 on. It has some limitations in features: no support of 3D mount simulator.
Warning
The installation for is dedicated for a 32bit system on Raspi4. If you plan to use a 64 bis system, please look to StellarMate64
