Three weeks ago to the day, “WWE Friday Night SmackDown” on Fox needed a savior. What it got was NXT Champion Adam Cole. Close enough.
With the vast majority of the “SmackDown” roster stuck on a tarmac in Saudi Arabia following the pro-wrestling company’s “Crown Jewel” pay-per-view, Cole and other close-enough stars from USA Network program “NXT” were rushed to the live Fox show.
“That ended up being one of the most wild days of my entire career,” the 30-year-old Cole, whose real name is Austin Jenkins, recalled to TheWrap. “I think that’s part of why it was so special and stuck out to so many people, because pretty much everyone was aware of how crazy that day was. But yeah, absolute blast of a night — really cool.”
Walk us through it, champ.

“I got to the building at 8:20, and I think me and [Daniel Bryan] ended up walking to the ring at 9:30,” he said. “There was very little time to prepare.”
That lack of preparation did not show inside the ring or outside of it.
Below are a few minutes of the main-event match between “SmackDown” Superstar Daniel Bryan and Cole, who put his title on the line that night.
Also Read:
Between his 8:20 p.m. ET arrival and that previously unplanned 9:30 main event, Cole, Bryan, and WWE Legends/NXT mentors Triple H and Shawn Michaels performed what will go down as one of the best live promos of 2019, setting up the dream match. It was all out of necessity, but the real-life mad scramble only heightened the fictional drama. (Note: This writer doesn’t like calling professional wrestling “fake,” but this is one special case where we really can’t call the events “preplanned” or “scripted” either.)
The scene with the two WWE Hall of Famers and two future ones had suspense, comedy, and timing that was remarkable considering Cole told us they didn’t get to practice or mark it out at all.
“I didn’t know [the promo] was needed until it was like 30 seconds before we shot it, just because everything that day was so hectic and so crazy,” Cole recalled. “And you’re preparing for a match, so I’m thinking, ‘OK, I’m probably gonna go out around then’ — and then I find out 10 minutes earlier I’m needed for this segment that’s about to happen.”

See the result play out via the video below.
“Honest to God — and normally it’s a scenario where everyone kinda gets together and figures out…[camera-] blocking and things like that — I walked in based on instinct,” he continued. “I knew I was gonna walk in at a certain point, but as far as the pace at which I had walked in and where I stood, that was all– they had trusted me that I’m gonna know where to walk and I’m gonna know when to walk in, which is, again, just another really cool thing.”
Also Read:
“One of the coolest things of that night is… you had no chance to really overthink anything. You’re almost on autopilot,” Cole said. “And fortunately, there was magic in the air that night and everyone just clicked on all cylinders.”
Cole performed some more of that magic Wednesday night in a ladder match that led USA Network’s “NXT” to its first total-viewer victory over relative newcomer “All Elite Wrestling: Dynamite” on TNT.
This weekend, fans can catch Cole at “NXT TakeOver: WarGames,” which will stream live on the WWE Network this Saturday at 7/6c. The “Survivor Series” pay-per-view will stream live on the WWE Network 24 hours later.
Yes, he’ll be “absolutely dead” by the end of all that, Cole told us.
“I’m just gonna lay in my hotel bed and not move,” he said, “there’s a very good chance of that.”

## Comparing Common Concurrency Patterns
### in Elixir and Erlang
???
* Who here knows Erlang / Elixir?
* Process is an Actor.
* They communicate through message passing, and each process has an ordered inbox.
* Concurrency & Parallelism are great, but you need to know how to use them.
* People are thinking about these things.
---
class: center, middle
![](/assets/images/pattern_language.png)
???
* Paper first published in 1999.
* Patterns are great, because they give us shared vocabulary.
* This makes communication easier, and that's the hard part of programming.
---
class: center, middle
![](/assets/images/ppp.jpg)
???
* Published by Addison-Wesley in 2004
* Great acronym!

## Comparing Common Concurrency Patterns
### in Elixir and Erlang
???
* I had kind of hoped there would be a really good acronym for the title for this talk.
---

???
* But then I remembered that this one was sort of taken already.
---
class: center, middle
![](/assets/images/PDSE-algorithm-structure.gif)
???
* The highlight (for me) from that original paper is this chart.
* It shows the basic layout of the patterns they identify and named.
* Now, because it's a 20 year old paper that was kind of hard to read, so I made this.
---

![](/assets/images/photo_2020-01-12_15-11-03.jpg)
???
* Now we see that we start at the beginning, and there are decision points that help us get to our
final pattern.
* Usually patterns aren't prescriptions, but in this case they are!
* But not all of them are really _for_ us.
* 20 years ago - and really to an extent still today - most people thinking about this aren't
thiking at our scale.
---
class: center, middle
![](/assets/images/supercomptuer.jpg)
???
* A lot of the research on this is for people doing theoritical astrophysics simulations with
giant supercomputers trying to do as much vector math as they can.
* But that doesn't mean we can't still benefit from a bit of this!
* Even though we aren't (and shouldn't) just do what they do cause "it's what they do at Google."

* So today we're going to look at three examples from open source.
* We'll look at some code, and we'll also look at some pictures.

projects!

## Embarrassingly Parallel
???
* Best name of them all!
* One example is sending emails.
---
class: padding
.center[
# Embarrassingly Parallel
]
```
def send_emails(emails) do # serial
Enum.map(emails, fn email ->
send_email(email)
end)
end
```
???
* Here we map over the list of emails, sending them in series.
---
class: padding
.center[
# Embarrassingly Parallel
]
```
def send_emails(emails) do # serial
Enum.map(emails, fn email ->
send_email(email)
end)
end
def send_emails(emails) do # parallel
Enum.map(emails, fn email ->
spawn(fn -> send_email(email) end)
end)
end
```
???
* Making this paralell is as simple as spawning one process per email.
---
class: padding
.center[
# Embarrassingly Parallel
]
```
def send_emails(emails) do # serial
Enum.map(emails, fn email ->
send_email(email)
end)
end
def send_emails(emails) do # parallel
Enum.map(emails, fn email ->
`spawn`(fn -> send_email(email) end)
end)
end
```
???
* Now they all send in parallel - great!

* Simplest, and probably one of the more common ones.
* But the most common one gives us just a little bit more.
---
class: center, middle, headline
## Reduction
???
* This one may be know by its other names - async/await & map/reduce.
* Quite a lot like Embarrassingly Parallel, but with one important difference.
---
class: padding

# Reduction
]
```
defmodule Parallel do
def map(collection, func) do
refs =
Enum.map(collection, fn element ->
Task.async(fn -> func.(element) end)
end)
Enum.map(refs, fn ref ->
Task.await(ref, :infinity))
end)
end
end
```
???
* We map over our input, partitioning it in some fashion (one element per child process)
* Then reduce the output of that partitioned work back into a single result.
---
class: padding
.center[
# Reduction
]
```
defmodule Parallel do
def map(collection, func) do
refs =
Enum.map(collection, fn element ->
`Task.async`(fn -> func.(element) end)
end)
Enum.map(refs, fn ref ->
`Task.await`(ref, :infinity))
end)
end
end
```
???
* We get a lot from the Task module
* I think it's important to go one level deeper here.

* Map in parallel, but reduction in series.
* Other ways to optimize, but this is generally ok.
* You could technically do this recursively for partitions of partitions.
* Let's look at an example to make it more clear.
---
class: padding
.hidden[
# _

me = self()
fun = fn seconds ->
Process.sleep(seconds * 1000) # Simulate some expensive work
send(me, Time.utc_now().second)

Time.utc_now().second #=> 48
```

Parallel.map([1, 2, 3, 1], fun) #=> [49, 50, 51, 49]
```
--
```
Time.utc_now().second #=> 51

* The computation is done in parallel, but reduce is done in series.
* And now in pictures!

## Asynchronous Decomposition
???
* As you might imagine, dealing with data structures of unknown - and posssibly infinite! - size
is a real bummer in languages like C where you need to pre-allocate memory.
* For us it's not so bad, but I think it's still significant enough of a differnce to deserve its
own pattern.

* In Elixir, test files aren't compiled - they're only compiled at run time.

to handle.

???
* Trust me - if you run your tests in parallel with shared dependencies it's going to be a really
bummer.
* Dependencies are more than just what's in memory! Databases, file systems, third-party
dependencies, etc!
* Could we simplify this and use Reduction here instead?

???
* Yeah, sure, kind of! It would be slower, but it would indeed work.
* The big difference here again is just the input - eagerly or lazily evaluated.
* Again, this is a much bigger difference when you're working in C or something, but it's still
important for clear communication.

* The other great thing about Asynchronous Decomposition is how it serves as a sort of middle
groud to this next pattern.
* This is what it sounds like. You may have heard of or seen other examples of this in the past.
* The thing is, doing this _right_ is actually quite hard, and so if you need to reach for this,
you really don't want to write your own.

Imagine going to the hospital and not worrying about health bills? The HyBasic plan will give individuals health cover up to N350, 000. This includes general consultations, minor surgeries, basic x-rays, diagnostic tests and so much more. Both the HyCheck and HyCheck Advanced plans allow you to take charge of your health and detect problems even before they start. The plans offer both standard and advanced health screenings that individuals need to get, all at a discounted price.
Speaking on the sales, the CEO of Hygeia HMO, Mr Obinnia Abajue said: “Every Nigerian deserves affordable coverage and high-quality care. For millions of Nigerians, quality healthcare is a luxury and with these sales, our already affordable healthcare plans become more affordable. We at Hygeia HMO will continue to contribute positively to the healthcare sector in Nigeria, and our Black Friday sale is a way of giving back to the society”.

If you haven't checked out see hear party yet, go do it! It combines GIF's from Giphy and music from SoundCloud into an energetic, epileptic and epic party visualizer. Made with <3 by @peterjavidpour;
One thing missing is a remote, so you and your friends can fight over which GIF to see or sound to hear.
Well now it's here! With the See-Hear-Party-Remote you can manage the GIF tag input, the SoundCloud search query, or navigate to the next track from multiple devices.
The See Hear Party site only works in the Chrome browser for now, so step 1 and 2 should be done in Chrome.
Visit See Hear Party; start the party; press the saved Bookmark and name your party place.
Visit the remote control with other devices, enter your party name, and start fighting over the remote!
You can even connect multiple See Hear Party sites with the bookmarklet, and share parties in each other's house!

Gentle Patron,
It came to me recently, as it has done many times before, that Life presents itself to us like a particularly devious sort of maze: one wherein not only must we twist and turn on our ways, oft encountering blank endings and curs’d loopings back, but in which even the labyrinthine pathways themselves are hidden from us, such that we must feel out the walls blindly, stubbing our toes and bruising both body and soul.
These are the cheery musings that inspired the ænigma below.
I should like you to draw the pathways of a single connected maze along the lines of the grid [above]. Each path must connect two of the circles I’ve laid out; the number in each circle indicates how many paths must connect to that circle. The two circles connected by each path must contain different numbers.
So as to prevent the individual paths themselves from being tedious, each path may bend by 90 degrees at most once. Paths may not touch or cross one another.
Once you’ve completed your maze, you must walk it to find the final answer to my ænigma. Note that two of the circles have been shaded; walk the route from the upper such circle to the lower, never revisiting a circle. Whenever you come to a fork in that route, where more than one option would lead you to your goal, prefer to turn right or, failing that, to continue straight. At each circle, including the first, advance the letter written therein forward in the alphabet (wrapping around from Z to A if necessary) by the final digit in the sum of all of the numbers so far encountered. Those letters will reveal a clue to your final answer.
Good luck!
Fill in your answer and give to a cashier at Ada's Technical bookshop for your prize. This month’s prize: one free non-alcoholic drink!
(Limit one per solver. Offer available through 31st July 2015.)
Please send an email to<EMAIL_ADDRESS>about any issues, bugs, or feature requests that come up.

CovidApp - Coronavirus Community Alert
Anonymously monitor your interactions and find out if you have been exposed to the virus, with no GPS tracking.
Our app anonymously monitors the devices that get near you, without using the GPS.
If you have been close to an infected person you will be notified and get clear instructions on the next steps to follow.
Download the apps
(Coming soon)
How it works
Every mobile device has a unique and anonymous numeric id, that can be read at distance using high-precision low-distance measurement technology.
CovidApp continuously scans your surroundings and collects the ids of the phones close to you, storing them in a secure centralized cloud database.
Our network of certified doctors daily updates the database with the ids of the devices belonging to confirmed Coronavirus infected.
CovidApp continuously scans your surroundings and collects the ids of the phones close to you, storing them in a secure centralized cloud database.
We are 100% anonymous
Our system relies only on the anonymous IDs generated by our service, that in no way can be used to obtain personal data.
Moreover:
DOESN'T track users' GPS positions.
DOESN'T need any login.
DOESN'T collect any privat or sensible data, such as name, surname, mobile number.
DOESN'T shows on a public map your health status together with the locations you visited or the place you live in.
All the produced code necessary for the functioning of the service is open source and available online for review: Coronavirus Outbreak Control
We are working with recognised Health Institutions and Research Centers
We are working very closely with the most recognised Health Institutions to distribute the service worldwide.
We collaborate with:
Raffaele Perego, Director of Research, ISTI-CNR
Vania Bogorny, Head of the Computer Science Graduate Program at Universidade Federal de Santa Catarina (UFSC) - Brazil
Stefano Leonardi, Full Professor at Sapienza University of Rome
We are supported by:

Help the economy of your country
When a case of coronavirus is detected, your country’s institutions have to backtrack all the patient activities: who the patient has spent his time with, where the patient has been, etc.
This operation is extremely expensive and requires lots of efforts.
When the number of infections grows to the point in which this operation can’t be applied to all the cases, governments have to quarantine towns, regions or, even worse, the entire country.
With our solution, we will immediately inform whoever has been close to the infected patient during the last 14 days to quarantine him/her-self and we will give him/her precise instructions about how to behave.
This new operation is free for the people, free for the Health Institutions and extremely fast. You can protect your country economy just by download this app.
Together we can save lives, share it now

Frances Hodgson Burnett
Frances Hodgson Burnett, (November 24, 1849 - October 29, 1924) was an English-American playwright and author. She is best known for her children’s stories, in particular The Secret Garden, A Little Princess, and Little Lord Fauntleroy. Born in Manchester, England, she emigrated to Knoxville, Tennessee in the United States after the death of her father in 1864. Following the death of her mother when she was 18 years old, Frances found herself head of the family of four younger siblings, and she turned to writing to support them. She is known for her talent to convey realistic details of working-class life.
- Nationality: English
- Birth Date: 24 Nov 1849
- Death Date: 29 Nov 1924
Available Works
- A Little Princess (1906)
- Sara Crewe is left in the care of Miss Minchin's Seminary when her father departs for India.
- The Secret Garden (1909)
- The Secret Garden (1909) is one of Frances Hodgson Burnett’s most popular novels. The book tells the story of Mary Lennox, a spoiled, contrary, solitary child raised in India but sent to live in her uncle’s manor in Yorkshire after her parents' death. She is left to herself by her uncle, Mr. Craven, who travels often to escape the memory of his deceased wife. The only person who has time for Mary is her chambermaid, Martha. It is Martha who tells Mary about Mrs. Craven's walled garden, which has been closed and locked since her death. Mary becomes intrigued by the prospect of the forgotten garden, and her quest to find out the garden's secrets leads her to discover other secrets hidden in the manor. These discoveries combined with the unlikely friendships she makes along the way help Mary come out of her shell and find new fascination with the world around her.

Ben + Claire Engagement Session
Portland, Oregon
December 2018
Ben and Claire traveled all the way from Texas to do engagement photos in the PNW. We met up on the shortest day of the year to capture their love story. We did some spins, listened to Sylvan Esso, popped some bottles, and even shot some of my favorite headlight photos to date! It was a blast getting to know these two during such a special time in their lives.

Arrived at DLD06
We made it to DLD06 and the place is getting really packed. We still got some seats upstairs and the show is about to start. They really put some money into this but the list of sponsors is impressive too. It will be nice to see what the next two days bring. One thing is to be remembered though… this is not so exclusive as it was planned to be with a lot more people being invited. <!– technorati tags start –>

To celebrate Nitobi's moving into new offices, we had an iPhone cake made by the good folks at The Uncommon Cake. They even added some PhoneGap apps to the phone, including A Binary Clock, NYC Tip, Ponderisms, Sales Targets, Entrepreneur and Questomatic. Click the image to see the full-size version.


Loading JavaScript is one of the biggest performance bottlenecks. A script tag causes the browser to halt rendering, load a file, and run the code (the script will be executed before parsing is resumed). For slow servers and heavy scripts this means that displaying the webpage will be delayed.
| HTML Parsing | ||
| HTML parsing paused | ||
| Script download | ||
| Script execution |
The browser will begin to download the deferred scripts in parallel without stopping page processing (during HTML parsing) and will only execute them after the parser has completed. A positive effect of this attribute is that the DOM will be available for the scripts.
The scripts downloaded with defer
are also guaranteed to execute in the order that they appear in the document.
The async
is identical to defer
,
except that the script executes at the first opportunity after download (will pause the HTML parser to execute it when it has finished downloading).
Typically you want to use async
where possible, then defer
then no attribute.
async
;defer
;async
script then use an inline script with no attributes placed above the async
scripts.


Honestly, this is an odd topic for me to approach.
Being a white male in the southern United States, I kinda fall right in the middle of the majority. So, I don't think I have ever personally been effected by stereotype threat.
However, I can see this being a problem within the tech world.
Society has decided upon a pretty specific stereotype for memebers of the technology world. When people close their eyes and imagine a coder they probably all see someone who is...
* Young
* Male
* White
I mean, just take a look at these two graphs that look at the founders of companies that received seed funding in 2010.
And now a break down racially.
I am not sure how much has changed in the past few years since this study was done, but I would bet that it's not significant.
With staggering numbers like this, it's really understandable that we are being asked to look into the subject. I really hope that DBC can make a dent in this issue by continuing to focus on creating graduates that understand the problem.
Thanks for reading!
