Generate a call to a vector intrinsic or runtime inlined function.
The arguments are sliced up into vectors of the width given by 'intrin_lanes', the intrinsic is called on each piece, then the results (if any) are concatenated back together into the original type 't'. For the version that takes an llvm::Type *, the type may be void, so the vector width of the arguments must be specified explicitly as 'called_lanes'.

AEW 'Dynamite' Results (11/13): Jon Moxley Speaks, Cody Rhodes Seeks Revenge, More
by Tom ClarkThe November 13 edition of AEW Dynamite emanated from the Nashville Municipal Auditorium in Nashville, Tennessee. The show was a followup to the company’s Full Gear event, which took place on November 9.
The show began with a flashback of Full Gear, including highlights of Jon Moxley versus Kenny Omega. Moxley was shown with the trainer, who was examining his scarred back after the match.
Jon Moxley defeated Michael Nakazawa
After the match, a fired up Moxley said that he and Omega were forever changed by their unsanctioned match on November 9.
The Dark Order defeated The Jurassic Express
After the match, Luchasaurus returned and laid waste to The Dark Order.
Darby Allin defeated Shawn Spears and Peter Avalon
Joey Janela ran down to the ring during the match and attacked Spears. This took Shawn out of the match, leaving Allin and Avalon in match. Darby hit the Coffin Drop for the win. Allin then told Moxley that he accepts the challenge.
Nyla Rose defeated Dani Jordyn
Tony Schiavone interviewed Allie on the ramp. She put over Nashville and was going to say something else, when suddenly the lights went down. When they cam.e back up, Awesome Kong and Brandi Rhodes appeared on the ramp behind Allie. Kong attacked her and Rhodes held Allie down so Kong could cut a piece of her hair.
Chris Jericho was out next. He entered the ring and said he proved to be the greatest of all time, following his win over Cody Rhodes at Full Gear. He once again demanded a thank you, but he wanted it from people that matter. He said he’s beaten everyone put in front of him. The lights went out and MJF came out to Cody’s pyro and music.
MJF said that fans have been booing him as if he’s the villain, but they’ve been cheering the guy who’s the villain all along, Cody. MJF said that Cody didn’t care about any of them, that he only cared about himself.  He also said that Rhodes wanted to make him a puppet, but that Cody’s thumb wasn’t big enough to hold him down.
Jericho spoke up and said he heard MJF wanted to be in The Inner Circle. But MJF mocked the group and and repeated Jericho’s bubbly line. Chris then talked about the days of WCW, eventually leading to Cody’s arrival. He stormed the ring and fought both Jericho and MJF until Wardlow suddenly appeared and destroyed Rhodes.
PAC defeated Hangman Page
After the match, The Young Bucks were shown brawling with Proud & Powerful backstage. Santana came off the top of a forklift during the brawl and all of this led to a bathroom door being slammed open. Orange Cassidy was inside and said nothing, as the door was then pulled closed.
The brawl continued during the commercial break and then went to the stage. Santana took a blackjack to Nick’s leg, then spray painted a bullseye on the ramp, putting Matt Jackson through it.Brandon Cutler came out to make the save, but was beaten down as well. Private Party came out as well and this finally brought the brawl to an end.
Proud & Powerful versus Private Party and Jon Moxley versus Darby Allin were both advertised for the November 20 edition of Dynamite.
SoCal Uncensored retained the AEW World Tag Team Championships vs. Chris Jericho and Sammy Guevara w/ Jake Hager
Scorpio Sky pinned Jericho to get the win and the champ was stunned. Chris wreaked havoc outside the ring as the show went off the air.

public interface SpiMaster
An interface for controlling an SPI module, in SPI bus-master mode, enabling communication with multiple SPI-enabled slave modules.
SPI is a common hardware communication protocol, enabling full-duplex,
synchronous point-to-multi-point data transfer. It requires MOSI, MISO and
CLK lines shared by all nodes, as well as a SS line per slave, connected
between this slave and a respective pin on the master. The MISO line should
operate in pull-up mode, using either the internal pull-up or an external
resistor. SpiMaster instances are obtained by calling
IOIO.openSpiMaster(DigitalInput.Spec, DigitalOutput.Spec, DigitalOutput.Spec, DigitalOutput.Spec[], SpiMaster.Config)
.
The SPI protocol is comprised of simultaneous sending and receiving of data between the bus master and a single slave. By the very nature of this protocol, the amount of bytes sent is equal to the amount of bytes received. However, by padding the sent data with garbage data, and by ignoring the leading bytes of the received data arbitrarily-sized packets can be sent and received.
A very common practice for SPI-based slave devices (although not always the case), is to have a fixed request and response length and a fixed lag between them, based on the request type. For example, an SPI-based sensor may define the the protocol for obtaining its measured value is by sending a 2-byte message, whereas the returned 3-byte value has its first byte overlapping the second value of the response, as illustrated below:
Master: M1 M2 GG GG Slave: GG S1 S2 S3M1, M2: the master's request
The IOIO SPI interface supports such fixed length message protocols using a
single method, writeRead(int, byte[], int, int, byte[], int)
, which
gets the request data, and the lengths of the request, the response and the
total transaction bytes.
The instance is alive since its creation. If the connection with the IOIO
drops at any point, the instance transitions to a disconnected state, in
which every attempt to use it (except Closeable.close()
) will throw a
ConnectionLostException
. Whenever Closeable.close()
is invoked the
instance may no longer be used. Any resources associated with it are freed
and can be reused.
Typical usage (single slave, as per the example above):
// MISO, MOSI, CLK, SS on pins 3, 4, 5, 6, respectively.
SpiMaster spi = ioio.openSpiMaster(3, 4, 5, 6, SpiMaster.Rate.RATE_125K);
final byte[] request = new byte[]{ 0x23, 0x45 };
final byte[] response = new byte[3];
spi.writeRead(request, 2, 4, response, 3);
...
spi.close(); // free SPI module and pins

DigitalOutput.Spec, DigitalOutput.Spec[], SpiMaster.Config)

The first thing that you will need to do is install RVM. To do this open a terminal and enter in the following command (please note, you will need to make sure you have git installed):
{% highlight sh %} bash < <(curl -s https://rvm.beginrescueend.com/install/rvm){% endhighlight %}Once the install finishes you will be instructed on how you can update your .bash_profile file with a load path to the rvm executable. Once that is done and the file has been saved you can simply type the follwoing into your terminal window to reload your shell (you can also just close and re-open your terminal window):
{% highlight sh %} source .bash_profile{% endhighlight %}Great, now that we've gotten that out of the way it's super simple to install new Ruby versions. Say you want to install Ruby 1.9.2, all you need to do now is type:
{% highlight sh %} rvm install 1.9.2{% endhighlight %}To use an installed Ruby use the following (substitute the version you want):
{% highlight sh %} rvm use 1.9.2{% endhighlight %}Wondering which Ruby versions are available for download?
{% highlight sh %} rvm list known{% endhighlight %}Want to know which you already have installed?
{% highlight sh %} rvm list{% endhighlight %}What About Rails?
Now that you know how to install different Ruby versions we can talk about how you can have different Rails environments. Let's say we have installed Ruby 1.9.2 and we are currently using that version and we want to try out Rails 3.1 without messing with any of our Rails 2.x applications. To do this we need to create what RVM calls a gemset. This will create a separate container where we install gems for a particular purpose.
{% highlight sh %} rvm gemset create rails31{% endhighlight %}This will create a new gemset called "rails31". Now all we need to do is switch into that gemset:
{% highlight sh %} rvm gemset use rails31{% endhighlight %}
This will place us into the rails31 gemset. You can see this by running
gem list
which will return a very short list of gems. Now we
can install Rails 3.1. WARNING!!! When you install gems
with RVM you will never want to use `sudo' when calling `gem install' while
using one of the RVM installed rubies.  The following command
assumes that the Rails team hasn't released another version of Rails
since 3.1.
Now we have Rails 3.1 installed in it's own contained gemset. We can now play around with it and not worry how installing this will effect our other applications running older Rails version. To get back out of this gemset simply call (assuming we still want to use the 1.9.2 Ruby version):
{% highlight sh %} rvm 1.9.2{% endhighlight %}There is a lot more information on RVM and how to use it including some pretty cool (and useful) advanced features. I highly recommend you look over the documentation on RVMs website.

Sunbird manages documentation similar to how it manages code. The docs are in a Github repository as Markdown documents. If you’re comfortable using Git and Github for source code or any other work, you’ll find editing and updating Sunbird documentation a breeze.
You may want to brush up on Markdown syntax. Here’s a handy Markdown guide and cheat sheet.
Writing Guidelines
Just as the Sunbird code follows coding standards and guidelines, the documentation has some simple conventions to follow. Please see the How to structure a document? section and the Sunbird style guide which follows to ensure the pages you submit are consistent with the rest of Sunbird’s documentation.
How to structure a document?
 Developing a simple framework for your writing before you start can save considerable time and will prevent the text from meandering.
Unless the information is structured logically, it is not easily understood, usable or readable. Titles of the main sections as headings and subheadings within the text help readers navigate through the piece. Even if you do not desire to have the section titles in the finished piece, they will help you as an author to structure your writing to the desired framework.
There are no set rules to structuring your content. However, the following is a brief guide that may be helpful.
Logical Hierarchy
Follow a logical hierarchy for your content. Most content is structured into subject, book, chapter, section, subsection, page; with subject being the largest chunk and a page the smallest. For example,
Sunbird > Installation > Installing Sunbird on Laptop > Prerequisites > Hardware Requirements
Page Structure
After you have decided the logical hierarchy for your content, structure each page with a logical hierarchy to make it readable and complete. Use headings and subheadings to build the logical structure of the page. For Sunbird, you can use three levels of headings.
Other than heading levels, you can structure the information on a page using paragraphs, tables, ordered (numbered) or unordered (bulleted) lists, infographics viz. diagrams, charts, images and notes.
Styles
You can use the following styles when formatting your document.
Titles and headings
Use short descriptive titles. Titles should be 80 characters or fewer. Avoid redundancy. For all main headings and subheadings use title case: only the first letter of the first word is capitalized. Everything else except proper names is in lowercase. (Sunbird is a proper name)
General text
Use short and appropriate sentences. Try to write in a very clear and concise manner. Avoid using jargons and words that are hard to understand. Be specific about who your audience is.
Sentence length
Keep sentences to 15 words or fewer. Do not be wordy. Long sentences are difficult to understand.
Blocks
Code segments are usually written in blocks. Use blocks if code segments are more than one line.
Contractions
Avoid using contractions, rather use the full word itself.
Procedure style
For sequential steps, use a numbered (ordered) list. For a set of options, use bullets (unordered list). When describing actions, avoid unnecessary words.
Punctuating lists
Precede an ordered or bulleted list with a sentence or phrase ending in a colon. For example;
In communities, you can：
-
Get to know other Sunbird users
-
Collaborate on projects in a small group
-
Voice your opinion on a particular project
Begin each item with a capital letter (unless it is a product or company name that begins with a lowercase letter).
Note: Complete sentences in a list should have a period at the end. If a line item is not a complete sentence, do not use a period. If you are breaking a sentence into a list, as in the first example in this section (In communities), periods aren’t necessary.
Be consistent, if possible, when writing the items in the list. Make them “parallel.” In the first example, Get, Collaborate, and Voice are the same form of verb.
Numbers, Dates and Time
Numbers
-
A billion is defined as an American billion: 1,000,000,000
-
Thousands should be separated by commas, i.e 100,000
Dates
Express dates either in full (December 6, 2008) or use the proper ISO date format: yyyy-mm-dd, as in 2008-12-06, depending on where it is being used. This may be unfamiliar to some users of American English, but the ISO standard is the widely-accepted date format for modern software.
Time
ISO 8601 uses the 24-hour clock system. The basic format is [hh][mm][ss] and the extended format is [hh]:[mm]:[ss], for example 13:47, or 13:47:30.
Hyphens
Use em dashes (HTML entity 8212, “—”) for abrupt breaks in a sentence, to temporarily change subject within a sentence, for clarity, to draw attention to a point, or to signify the origin or author of a quotation.
-
Donot use double hyphens; use the HTML entity.
-
Donot place spaces on either side. There shouldn’t be any space between the word or words next to an em dash and the en dash.
Use an en dash (HTML entity 8211, “–”) to indicate a range of numbers or dates. (See www.alistapart.com/articles/emen/ for more information about the subject of dashes and hyphens.)
Links
When embedding a link in a documentation page, always make sure the link text describes the destination of the link. “Click here” is not a good description, because it does not tell the user where the link will take them. If you can’t fully describe the destination of the link and still maintain good sentence flow, add a title tag. Title tags, used appropriately, are important for making the pages accessible.
Voice
- Reinforce the Sunbird brand: Anything written at Sunbird.org becomes part of the Sunbird experience and conveys the Sunbird spirit.
Always try to be:
* clear, simple, and concise
* respectful, honest, and approachable
* engaging, welcoming, lively, and fun where appropriate
* Use ordinary, everyday language instead of words that sound more elevated.
- Know your audience: Tone of voice, use of jargon, and complexity of language should be appropriate for the type of page:
- Major landing pages must be approachable and appropriate for a wide audience that could include beginners, company managers, designers, developers, business owners, first-time bloggers, tech-savvy entrepreneurs, educational organizations, or advanced Sunbird developers. Keep them in mind.
- Use empathy: Put yourself in the place of the readers. Try to look at your text through the eyes of a variety of visitors.
- You don’t need the word “Please” in order to sound friendly. At times, it will be appropriate; usually, it will not. It sometimes comes across as condescending.
- Get them there: Ask yourself what visitors want to get done and help them get there quickly.
- Short isn’t always best: Concise (brief yet comprehensive) is good, but shortness? It depends. What does the user expect and need?
- Open source not market-speak: Avoid fluffy sales talk. “We’re great! Sunbird is great!” “We’re the best!” These sentences are only believed by those who write them, not those who read them. Words such as “very, really, truly” tend to weaken a statement, not strengthen it.
- Edit and edit again: Strip away unnecessary words. Examine them. Is each one lively, direct, and doing a job? Or, is it empty or deadening? Because an informal voice is brand-consistent, complete sentences aren’t always necessary. Eg.: This module reduces the time you need to set up a forum. This can be written as : This module reduces forum set-up time.
- Be clear about benefits for the reader: Sunbird is here to make people feel privileged and awesome at what they do. Using the word “you” can be powerful.
- In general, use active, not passive, voice: In active voice, the subject performs the action (“The dog ate the bone.”). In passive voice, the subject is the target of the action (“The bone was eaten by the dog.”). Don’t twist sentences into knots trying to avoid this, though. Also, at times, passive voice emphasizes words that active voice would downplay. In that case, use passive voice, but, in general, use it sparingly.
- Avoid first-person: Avoid first-person (I, we, my, our) on editorial/landing pages. Use “Sunbird” instead. At times, because Sunbird is community-based, use “we” to sound inclusive or to reinforce the community concept.
- Balance the needs of new and experienced users. Provide links to additional or clarifying information new users may not know. At the same time, experienced users need quick steps.
- User-test your writing: Choose at least one person from your intended audience to make sure directions are clear and complete, and the tone is correct. User-testing is critical for sections like Modules and Documentation. If it is written for a new user with basic skills, you should test it on new users with basic skills. They should be able to achieve the final goal just by reading and following the directions, without asking you any questions.

Monster Hunter's Resident Evil quest is worth it for Tofu alone
Become zombified in the event quest 'Return of the Bioweapon'
by Jordan DevoreMonster Hunter World: Iceborne and Resident Evil 2 have entered an unholy union, and I'm extremely here for it. It's a gift. The limited-time in-game event runs until December 5, 2019 for Master Rank players who are MR20 or higher and can hold their own against an extra-nasty Blackveil Vaal Hazak.
Along with a zombie-themed event quest and a chance to dress up like Leon Kennedy and Claire Redfield, Iceborne players can also spruce up their rooms with a classic typewriter and item box.

First things first, though: that event quest. It's called RE: Return of the Bioweapon. Your initial instinct might be to bulk up on effluvia countermeasures but, as the intro screen warns, there's a twist.
"In this quest, instead of being afflicted with effluvium, you'll become zombified if you're hit by an effluvium-based attack. This also means that effluvium-resistant skills are neglected."
Zombification has pros and cons. In this state, you won't react to damage, your health will auto-recover in areas with effluvium, and you'll be immune to acid pools. That's all well and good. But while you're a zombie, you'll also shamble around, lose the dodge/evade ability, and most items can't be used.
To un-zombify yourself, you'll want to use Green Herbs – not to be confused with the normal green-colored herbs – which have sprung up throughout Rotten Vale. In a nice little extra nod, you can scrounge for Red Herbs and combine them with Green Herbs for a more potent recovery item.
The fight against Blackveil Vaal Hazak is otherwise business as usual. In other words: don't be afraid to leap. I'd advise bringing a Cleanser Booster along to make life easy when he starts getting spammy.
In exchange for beating Return of the Bioweapon, you'll earn a new type of crafting item, the S.T.A.R.S. Badge, which you can use to make the fancy new Resident Evil 2-themed gear.
Be sure to chat up the Housekeeper back in Seliana afterward. You'll get two zombie gestures and a pair of delivery quests: Type to Save Your Life and Good Ol' Item Box. You can then turn these quests in at the Resource Center – they require one S.T.A.R.S. Badge each – to get a typewriter and item box for your room. You should! There are home decorations like blood-soaked rugs and a Mr. Raccoon doll, too.
If you're into pendants (who isn't?), you can spend your S.T.A.R.S. Badges to craft pendants that resemble the R.P.D. badge, the Umbrella logo, and Tofu. It wiggles. I mean it really, truly wiggles. I love it!
Lastly, the crossover includes Resident Evil 2 armor sets. They're a bit too uncanny for me, but if you appreciate the novelty, here's what you'll need to craft the Leon and Claire outfits in Iceborne:
Leon α+
- S.T.A.R.S. Badge (x6)
- Pure Dragon Blood (x3)
- Shadowpierce Fang (x2)
- Deathweaver Membrane (x2)
Claire α+
- S.T.A.R.S. Badge (x6)
- Pure Dragon Blood (x3)
- Vaal Hazak Fellwing (x2)
- Deathweaver Membrane (x2)
The unsettling Mr. X costume for the handler is a paid add-on. Its usage should be outlawed.

Several layers all in one method
CQRS states that every method should either be a command that performs an action, or a query that returns data to the caller, but not both. In other words, Asking a question should not change the answer. More formally, methods should return a value only if they are referentially transparent and hence possess no side effects.
GraphQL is, in fact, inspired by CQRS!

field.Event sourcing persists the state of a business entity such an Order or a Customer as a sequence of state-changing events. Whenever the state of a business entity changes, a new event is appended to the list of events. Since saving an event is a single operation, it is inherently atomic.

The Toyota Supra is coming back to Forza Horizon 4
by Sherif SaedToyota is on its way back to Forza, starting with the 1998 Supra RZ in Forza Horizon 4.
Microsoft has announced that Toyota cars are coming back to Forza Horizon 4. This all starts with the iconic 1998 Supra RZ, which should be familiar to anyone who played street racing-themed games in the past.
The Supra arrives as part of Forza Horizon 4’s Series 17 update, due out on December 12, though it’s not yet clear if more will follow.
The reason this is big news is that Toyota has been absent from many racing games for a couple of years now. Its cars were missing in Horizon 4, as well as Need for Speed: Payback/Heat and even Grid. Although trucks could be found in Forza 7, the company later revealed it has an exclusive deal with Polyphony Digital, since Gran Turismo Sport is the only recent game that featured Toyota cars.
Toyota UK’s official Twitter account confirmed back in August that the company has no plans to license its cars to games other than Gran Turismo.
This could indicate a return for Toyota cars to racing games in general, but we’ll have to wait and see. For now, Forza Horizon 4 players can look forward to tuning a street racing icon next month.
