1) Use the Line Tool to Start Sketching the Paperclip
2) Use the 3 Point Arc Tool to Sketch the Curve of the Paperclip
3) Finish the Sketch of the Paperclip with the Line Tool and 3 Point Arc Tool
4) Use the Plane Tool to Create a New Plane at an End of the Paperclip
5) Use the Circle Tool to Create the Cross-Section of the Paperclip
6) Use the Sweep Tool to Make the Paperclip 3D
*) Use the Appearance Panel to Give your Paperclip some Color
We used ARC, LINE, PLANE, CIRCLE, and SWEEP.
Start off by creating a line anywhere on any plane. Here, we chose the Top plane and chose to sketch some distance away from the origin. However, to make our lives easier for a later step, we chose to start the line on the same horizontal axis (looking at it from the Top plane view).
You can use the Dimension tool to make this line a specific length. This is one side of the paperclip, and we put 1.5 inches.
Within the same sketch, click out of the Line tool and select the 3 Point Arc tool. We chose to make the paperclip as wide as the space between the initial line sketch and the origin.
With the 3 Point Arc tool, click once on the endpoint of the initial line sketch that lies on the same axis as the origin, then click again on the origin point. The last click determines the radius; make the radius the same all-around by clicking where the radius is "locked."
Essentially repeat the first two steps to finish off the paperclip as best as you can.

Click on the plane tool to create a new Front plane, or the plane that is perpendicular to your paperclip sketch. Use the Top view (or whichever view your paperclip is on) to make it easier to see.
Remember the first step, which was to draw a line. Try to offset your plane to the other end of that line (essentially where the paperclip starts). Also remember that we dimensioned it in the first step. This is where dimensioning it makes it easier. Simply offset the plane to however long you made that line. In our case, we will offset it by 1.5 inches since that is how long we made the line in Step 1.
On the new plane that you just made, use the circle tool to sketch a small circle at the end of the first line sketch that you drew.
Remember to make the circle relatively small since this circle is essentially the thickness of the paperclip.
Click on the sweep tool, which will prompt you to choose a face and a sweep path. Select the circle as the face. Then select the lines and the arcs that you drew as the sweep path: click on each part of it and you will see the sweep function working.
Click the green check mark once you have finished.
Either right click on your new paperclip or go to the right and click on the Appearance Panel.
Use the Palette or the Mixer to choose a color.

Can Chorley cut out carbon emissions by 2030?
by Paul FaulknerChorley should aim to become a carbon-neutral borough by 2030, councillors have said.
The target would put the district on a path to achieve net zero carbon emissions some 20 years earlier than the date which the government has set for the rest of the country.
READ MORE >>> Does Lancashire need to have a conversation about climate change?
The move came as Chorley Council became the latest in Lancashire to declare a “climate emergency”.
Leading the call, Labour councillor Steve Holgate said he was persuaded of the threat posed by climate change two decades ago.
“I wish I’d been wrong, but we’ve got the evidence now to prove it,” Cllr Holgate said.
“It’s not like it was 30 years ago when there was just a rumour that there was something wrong. We now have to do everything in our power to make [the necessary changes] happen.”
As part of the motion approved by members, the council will write to government requesting the devolved powers which it needs to make achieving the 2030 target possible.
The authority has already set up a working group to promote the “green agenda” in the borough, with the intention of developing an action plan of specific measures.
There was unanimous support in the chamber for the declaration of the climate emergency and acceptance of the dangers posed by climate change, but the Conservative opposition group urged caution over adopting such an ambitious target date for eliminating carbon emissions.
“I can’t see how we can make Chorley carbon neutral by 2030 – it’s virtually impossible,” said Cllr John Walker, suggesting that the borough aim for the national deadline of 2050.
“There’s far too much to do – all gas boilers would have to be replaced. What about petrol and diesel cars – will people have to get rid of them by 2030?”
Cllr Holgate said that his proposal was a target – and was not “committing people to something which cannot be achieved”. While Cllr Walker said he stood by his concerns, he withdrew his amendment to make 2050 the carbon neutral date in Chorley.
Neighbouring South Ribble Borough Council made a similar commitment to going carbon neutral by 2030 earlier this year, but later clarified that it applied to the local authority itself and its suppliers, rather than the district as a whole.
Several Chorley councillors said that a demanding target was just what the climate emergency demanded.
“Unless we set ourselves a tough challenge, we aren’t going to make the effort,” Cllr Laura Lennox said.
“There is nobody in the whole world who is [solely] responsible for climate change – everybody is responsible,” she added.


Obliv-C: A Language for Extensible Data-Oblivious Computation
1/Jan 0001
Obliv-C: A Language for Extensible Data-Oblivious Computation
Obliv-C is a simple GCC wrapper that makes it easy to embed secure computation protocols inside regular C programs. The idea is simple: if you are performing a multi-party distributed computation with sensitive data, just write it in our Obliv-C langauge and compile/link it with your project. The result will be a secure multi-party cryptographic protocol that performs this operation without revealing any of the inputs or intermediate values of the computation to any of the parties. Only the outputs are finally shared.

Mourinho likens Son to Ronaldo after stunning solo goal
London: Tottenham Hotspur FC coach Jose Mourinho says his team’s ace winger Son Heung-mins sensational solo goal against Burnley reminded him of a goal Brazilian star Ronaldo scored for Barcelona during the his tenure at the Spanish side.
Tottenham were leading 2-0 through goals from Harry Kane and Lucas Moura in the 4th and 9th minute respectively late on Saturday, the South Korean Son picked up the ball on the edge of his area beforemaking some great dribbling attempts and beat several defenders before finding the back of the net in the 32nd minute.
Later, Moussa Sissoko and Kane scored later in the game to help Mourinho’s side register an emphatic 5-0 win at home.
“Son’s is a tremendous goal. Harry’s two goals from outside the box and the pass for the Moussa goal. A couple of better passes or choices and we could have had more,” Mourinho was quoted as saying by BBC Sport.
“I remember when I was at Barcelona with Bobby Robson and Ronaldo Nazario scored a goal similar to Son’s. And this was an amazing goal. I know that he is going to reach the face of the keeper and the control… he is unstoppable. The keeper is good, though, but he managed to put it in,” he added.
Mourinho was referring to a goal by the then striker Ronaldo against Compostela early in the 1996-97 season.
Further commenting on the match, the coach said: “A perfect day. No injuries, a clean sheet, goals, perfect football, kids coming on for their first Premier League football.” IANS

Most users of ChemSpider’s API services will have to apply rate limiting conditions. Such a rate limit could be, for example, “no more than 15 queries per minute”. The following two paragraphs describe how to rate-limit any chemspiderapi
function; both in base
R (using ratelimitr
) and tidyverse
coding styles.1
To run both examples, the ratelimitr
package and the tidyverse
package collection need to be installed. The necessary API key is retrieved from a stored keyring using the keyring
package; see separate vignette “Storing and Accessing API Keys” for instructions and recomendations on how to handle system-wide keys.
To start working with rate-limiting, the miniature demo data from chemspiderapi
will be used. The data set is immediately available once chemspiderapi
is loaded.
## Loading chemspiderapi
library(chemspiderapi)
## Loading the demo data
data("demo_chemicals")
## Looking at the demo data
demo_chemicals
#> Name InChIKey
#> 1 Caffeine RYYVLZVUVIJVGH-UHFFFAOYSA-N
#> 2 Bisphenol A IISBACLAFKSPIT-UHFFFAOYSA-N
#> 3 Benzo(a)pyrene FMMWHPNWAFZXNH-UHFFFAOYSA-N

#> 5 N,N-Diethyl-meta-toluamide MMOXZBCLCQITDF-UHFFFAOYSA-N
base
R exampleIn base
R, chemspiderapi
functions can be re-wrapped into functions that introduce a waiting time using Sys.sleep()
. These rate-limited functions can then be used in, for example, the apply()
family . Before diving into the rate-limiting, the API key needs to be retrieved.
## Retrieving the API key from the keyring package.
## Note that the keyring package is not loaded, but only the keyring::key_get() function is called.
apikey <- keyring::key_get(service = "ChemSpider API key", username = Sys.getenv("USERNAME"))
We will now create a rate-limited version of the post_inchikey()
function and use it to obtain a query ID.
## The sleep_post_inchickey() function will automatically "sleep" for four seconds before returning its result.
## This means it will run each query with a four second sleep in between, resulting in 15 queries per minute.
sleepy_post_inchikey <- function(...) {
result <- post_inchikey(...)
Sys.sleep(4)
result
}
## sapply() can be used in this context because the result of each iteration is a single vector.
demo_chemicals$queryId <- sapply(X = demo_chemicals$InChIKey, FUN = function(x) sleepy_post_inchikey(inchikey = x, apikey = apikey))
demo_chemicals
We can now check the status of query with a rate-limited get_queryId_status()
function.
sleepy_get_queryId_status <- function(...) {
result <- get_queryId_status(...)
Sys.sleep(4)
result
}
## As the result of the query is an array, lapply() is used.
demo_chemicals$status <- lapply(X = demo_chemicals$queryId, FUN = function(x) sleepy_get_queryId_status(queryId = x, apikey = apikey))
demo_chemicals
All queries need to report the status Complete
before proceeding. If this is the case, the ChemSpider IDs for the queries can be retrieved using a “sleepy” get_queryId_results()
function.
sleepy_get_queryId_results <- function(...) {
result <- get_queryId_results(...)
Sys.sleep(4)
result
}
## mapply() is used because the input covers two columns
demo_chemicals$id <- mapply(FUN = function(x, y) sleepy_get_queryId_results(queryId = x, status = unlist(y)[1], apikey = apikey), x = demo_chemicals$queryId, y = demo_chemicals$status)
demo_chemicals
Finally, the details for the chemicals can be retrieved using a rate-limited get_recordId_details()
function.
ratelimitr
exampleIn this example, the ratelimitr
package will be used to rate-limit chemspiderapi
functions. To use the rate-limiting functionalities, we need to load ratelimitr
## Loading the ratelimitr package
library(ratelimitr)
## Re-setting the demo data
data("demo_chemicals")
## Note that the API key is already available from the previous example!
We will now create a rate-limited version of the post_inchikey()
function and use it to obtain a query ID.
## In ratelimitr::limit_rate(), the ratelimitr::rate() function specifies the rate limit as calls per second.
limit_rate_post_inchikey <- limit_rate(post_inchikey, rate(n = 15, period = 60))
## sapply() can be used in this context because the result of each iteration is a single vector.
demo_chemicals$queryId <- sapply(X = demo_chemicals$InChIKey, FUN = function(x) limit_rate_post_inchikey(inchikey = x, apikey = apikey))
demo_chemicals
We can now check the status of query with a rate-limited get_queryId_status()
function.
limit_rate_get_queryId_status <- limit_rate(get_queryId_status, rate(n = 15, period = 60))
## As the result of the query is an array, lapply() is used.
demo_chemicals$status <- lapply(X = demo_chemicals$queryId, FUN = function(x) limit_rate_get_queryId_status(queryId = x, apikey = apikey))
demo_chemicals
All queries need to report the status Complete
before proceeding. If this is the case, the ChemSpider IDs for the queries can be retrieved using a rate-limited get_queryId_results()
function.
limit_rate_get_queryId_results <- limit_rate(get_queryId_results, rate(n = 15, period = 60))
## mapply() is used because the input covers two columns
demo_chemicals$id <- mapply(FUN = function(x, y) limit_rate_get_queryId_results(queryId = x, status = unlist(y)[1], apikey = apikey), x = demo_chemicals$queryId, y = demo_chemicals$status)
demo_chemicals
Finally, the details for the chemicals can be retrieved using a rate-limited get_recordId_details()
function.
tidyverse
exampleIn the tidyverse
ecosystem, all relevant chemspiderapi
functions can be used in functional programming approaches using the purrr::map()
family. purrr::slowly()
can be used to limit the number of calls of chemspiderapi
functions in a given time interval.
## Loading the tidyverse package family
library(tidyverse)
## Re-setting the demo data
data("demo_chemicals")
## Note that the API key is already available from the previous example!
## Using purrr::slowly() and purrr::rate_delay() to rate-limit the post_inchikey() function.
## In this example, we introduce a pause of four seconds and use the verbose output (`quiet = FALSE`).
slowly_post_inchikey <- slowly(post_inchikey, rate = rate_delay(pause = 4), quiet = FALSE)
The post_inchikey()
function is now rate-limited as slowly_post_inchikey()
. We can now use it to POST the five InChIKeys of the demo data.
tidyverse_demo <- demo_chemicals %>%
as_tibble() %>%
mutate(queryId = map_chr(InChIKey, ~ slowly_post_inchikey(inchikey = .x, apikey = apikey)))
tidyverse_demo
In the next step, the queryId status needs to be checked using the get_queryId_status()
function. This function as well needs to be rate-limited into slowly_get_queryId_status()
before use.
slowly_get_queryId_status <- slowly(get_queryId_status, rate = rate_delay(pause = 4), quiet = FALSE)
tidyverse_demo <- tidyverse_demo %>%
mutate(status = map(queryId, ~ slowly_get_queryId_status(queryId = .x, apikey = apikey))) %>%
unnest(status)
tidyverse_demo
Ideally, the status column only contains Complete
. If this is the case, the results can be retrieved using a rate-limited slowly_get_queryId_results()
function.
slowly_get_queryId_results <- slowly(get_queryId_results, rate = rate_delay(pause = 4), quiet = FALSE)
tidyverse_demo <- tidyverse_demo %>%
mutate(id = map2_int(queryId, status, ~ slowly_get_queryId_results(queryId = .x, status = .y, apikey = apikey)))
tidyverse_demo
The id column contains the ChemSpider IDs for the five chemicals; or rather their InChIKeys. We can now obtain details for the chemicals using the rate-limited version of get_recordId_details()
.
Technically, using the purrr
package would be sufficient, but in practice most users will likely use the entire tidyverse

6 times the US military totally screwed up on Twitter
by Sam Fellman, Ryan Pickrell, Business Insider US- The military has codified the rules for managing these official accounts. But sometimes these social-media pros flub it.
- The screw-ups range from the Pentagon’s threat to bomb millenials converging near Area 51 to a “KnowYourMil” post about military systems that got it wrong.
Every day, scores of US military commands reach millions with posts aimed to inform and inspire: videos of valor, motivational photos, and, yes, puppy pics.
The military has codified the rules for managing these official accounts. But sometimes these social-media pros flub it – even the four-star command responsible for the US’s nuclear weapons.

#KnowYourMil
The Department of Defense’s official twitter account shared this stunning image of an armored vehicle firing at a training exercise with the tag, #KnowYourMil.
The only problem – they named the wrong armored vehicle.
That’s a Stryker armored vehicle firing its 105mm gun, not a Paladin self-propelled howitzer as the DoD tweet identified it. One easy way to tell them apart is that the Paladin is a tracked vehicle like a tank, unlike the eight wheels on a Stryker.
‘The last thing #Millennials will see if they attempt the #area51 raid today’
On Sept. 20, 2019, the Pentagon’s Defense Visual Information Distribution Service (DVIDS) tweeted out a warning to millennials planning to attend the “Storm Area 51” event that day, suggesting it was going to bomb them.
“The last thing #Millennials will see if they attempt the #area51 raid today,” the tweet read. The accompanying image was a B-2 Spirit bomber, a highly-capable stealth aircraft built to slip past enemy defenses and devastate targets with nuclear and conventional munitions.
The tweet prompted some backlash online, and the next day, DVIDS deleted the offending tweet and sent out a new one explaining that “last night, a DVIDSHUB employee posted a tweet that in NO WAY supports the stance of the Department of Defense.”
‘#Ready to drop something much, much bigger’
US Strategic Command, which oversees the US’s nuclear arsenal, ringed in 2019 with a reminder that they’re ready, at any time, to start a nuclear war.
Playing off the image of the ball dropping in New York City’s Times Square, STRATCOM’s official account posted a tweet that included a clip of a B-2 dropping bombs. The command apologized for the message.

#BRRRT
In May 2018, the internet was debating whether the word heard on a short audio recording was “Yanny” or “Laurel.” Then the US Air Force joined the debate, referring to a recent strike on Taliban.
“The Taliban Forces in Farah city #Afghanistan would much rather have heard #Yanny or #Laurel than the deafening #BRRRT they got courtesy of our #A10,” the official US Air Force Twitter account said.
 It can fire so rapidly – nearly 3,900 rounds a minute – that the sound of each bullet is indistinguishable from the previous one, blending into a thundering “BRRRT.”
The US Air Force apologized for the tweet and deleted it, acknowledging it was in “poor taste.”
‘I’m like really smart now’
In January 2018, President Donald Trump fired off a flurry a tweets defending himself in response to the headline-grabbing details in Michael Wolff’s book, “Fire and Fury.”
Trump said he was “like, really smart” and “a very stable genius.”
That prompted a tweet from comedian Mindy Kaling from her character in the office, with the caption: “You guys, I’m like really smart now, you don’t even know.”
The US Army’s official Twitter account liked Kaling’s tweet, to which she replied: “#armystrong”
By the following day, the US Army had unliked the tweet.
Tough. Bold. Ready.
In 2016, the US Navy celebrated the 241st year since the date of its creation with a tweet that combined three images into one: a warship, a fighter jet, and a painting of a historic battle.
But the birthday message didn’t go over well with one audience on Twitter: Turks.
The flag in that battle scene closely resembles that of Turkey, a NATO member and US ally, as Muira McCammon detailed in Slate.
The Turkish community on Twitter sharply criticized the US Navy, and the Navy deleted it.


18
1 David arranged his soldiers for the battle. He divided them into groups, and he appointed a commander for each one hundred soldiers and a commander for each one thousand soldiers.
2 He sent them out in three groups. Joab commanded one group, Joab's brother Abishai commanded a second group, and Ittai from Gath commanded the third group. David said to them, "I myself will go with you to battle."
3 But his soldiers said, "No, we will not allow you to go with us. If they force us to all run away, they will not be concerned about us.  To them, capturing you is more important than capturing ten thousand of us. So it would be better that you stay here in the city and send help to us."
4 The king replied to them, "Very well, I will do whatever seems best to you." So he stood at the city gate and watched while his soldiers marched out, group by group.
5 While they were leaving, the king commanded Joab, Abishai, and Ittai, "For my sake, do not harm my son Absalom!" And all the troops heard about this, that David had given this order to the three commanders.
6 So the army went out to fight against the Israelite soldiers who were with Absalom. They fought the battle in the forest where people from the tribe of Ephraim lived.
7 David's soldiers defeated Absalom's soldiers. They killed twenty thousand of them.
8 The battle was fought all over that area, and the number of men who died because of dangerous things in the forest was greater than the number of men who were killed in the battle.
9 During the battle, Absalom suddenly came near some of David's soldiers. Absalom was riding on his mule, and when the mule went under the thick branches of a large oak tree, Absalom's head was caught in the branches. The mule kept going, but Absalom was left dangling in the air.
10 One of David's soldiers saw what happened, and went and told Joab, "I saw Absalom hanging in an oak tree!"
11 Joab said to the man, "What?
12 The man replied to Joab, "Even if you gave me a thousand pieces of silver, I would not have done anything to harm the king's son.
14 Joab said, "I am not going to waste time talking to you!" Then he took three spears, went to where Absalom was, and thrust them into Absalom's chest while he was still alive, dangling from the oak tree.
15 Then ten young men who carried weapons for Joab surrounded Absalom and finished killing him.
16 Then Joab blew his trumpet to signal that they should not fight anymore, and his soldiers returned from pursuing Absalom's men.
17 They took Absalom's body and threw it into a huge pit in the forest, and covered it with a huge pile of stones.  So while Absalom was alive, he had built a monument to himself in the Valley of Kings near Jerusalem, in order that people would remember him. He put his name on the monument, and people still call it Absalom's Monument.
19 After Absalom had been killed, Zadok's son Ahimaaz said to Joab, "Allow me to run to the king to tell him the good news that Yahweh has rescued him from the power of his enemies!"
20 But Joab said to him, "No, I will not allow you to take news to the king today. Some other day I will allow you to take some news, but not today. If you took news today it would not be good news for the king, because his son is dead."
21 Then Joab said to David's servant who was from Ethiopia, "You go and tell the king what you have seen." So the man from Ethiopia bowed in respect to Joab, and started to run.
22 Then Ahimaaz said again to Joab, "Even though that man from Ethiopia is running, allow me to run behind him." Joab replied, "My boy, why do you want to do that? You will not receive any reward for your news!"
23 But Ahimaaz replied, "That does not matter, I want to go." So Joab said, "Very well, then, go." So Ahimaaz ran along another road through the Valley of the Jordan and arrived where David was, before the man from Ethiopia arrived.
24 David was sitting between the outer gate and the inner gate of the city. The watchman went up on top of the city wall and stood on the roof over the gates. He looked out and saw one man running alone.
25 The watchman called down and reported it to the king. The king said, "If he is alone, that indicates that he is bringing news." The man who was running continued to come closer.
26 Then the watchman saw another man running. So he called down to the gatekeeper, "Look! There is another man running!" And the king said, "He also is bringing some good news."
27 The watchman said, "I think the first man must be Ahimaaz, because he is running as Ahimaaz runs." The king said, "Ahimaaz is a good man, and I am sure he is coming with good news."
28 When Ahimaaz reached the king, he called out, "I hope that things will go well with you!" Then he prostrated himself on the ground in front of the king and said, "Your Majesty, praise Yahweh our God, who has rescued you from the men who were rebelling against you!"
29 The king said, "Is the young man Absalom safe?" Ahimaaz did not want to answer that question, so he replied, "When Joab sent me, I saw that there was a lot of confusion, but I do not know what it was about."
30 Then the king said, "Stand aside." So Ahimaaz stepped aside and stood there.
31 Suddenly the man from Ethiopia arrived, and said, "Your Majesty, I have good news for you!
32 The king said to him, "Is the young man Absalom safe?"
33 The king realized that he meant that Absalom was dead, so he became extremely distressed, and he went up to the room above the gateway and cried. While he was going up, he kept crying out, "O, my son Absalom! My son!

ZFBrowser Documentation
This asset allows you to embed a full copy of Chromium, the open-source core of Google Chrome, inside your game!
Product Page | Unity Asset Store | Changelog | Get Help
Documentation for v1.1.0.
Copyright © 2015-2017 Zen Fulcrum LLC
Quick Start
Basic Browser:
- If you are using OS X be sure to read these notes.
- Import ZFBrowser into your project.
- Grab
ZFBrowser/Prefabs/BrowserQuad
and drop it into your scene. - On this new object, set the URL to a site of your choice, such as
http://google.com/
- Fiddle with your camera so the quad fills most of the view.
- Hit play and interact with the web site.
Embedded assets:
- Start with the scene above.
- Create a folder called
BrowserAssets
right next to (not inside!) yourAssets
folder. - Create a file called
index.html
insideBrowserAssets
and put this in it:
Hello World!

- Set the URL for the BrowserQuad to
localGame://index.html
- Hit play.
Congratulations! You now have a browser in your game!
General
Important Note
This library is made possible by a number of third-party open source software projects!
Include a copy of ThirdPartyNotices.txt with your distributed product.
Supported Platforms
This plugin is available for the given platforms and architectures:
- Windows Standalone, 32- and 64-bit (Windows Standalone does not include WSA/UWP)
- OS X Standalone, 64-bit
Browsers can be previewed when running inside the Unity Editor on the following platforms:
- Unity Editor, Windows Standalone, 32- and 64-bit
- Unity Editor, OS X Standalone, 64-bit
At present, you must use the same OS you are targeting to preview in the Unity Editor. For example, you must be running the 64-bit Windows Unity Editor to preview browsers when targeting Windows Standalone x64.
A 64-bit Linux port is partially completed but too unstable for distribution at this time. If you're excited to see this reach completion, send me an email.
This Asset does not includes licenses for proprietary or patent-encumbered codecs such as h.264 and mp3. Consider re-encoding your content with an open codec supported by Chromium or use consider using Adobe Flash to play your content.
OS X Users
- By default, your new Unity project will target universal builds, you'll need to change it to x64 before you can build and run your application.
- The Asset Store strips the executable bit off our child process. After importing the Asset, run a browser in the editor's playmode at least once before exporting a build. This will ensure the permission gets added back so the system can run.
- When running under the Unity Editor in OS X (or Linux), an extra layer of indirection must be used to avoid library conflicts. This reduces performance in the editor. Run a standalone build to see actual performance.
- At present, OS X builds must be made from OS X.
Scripting
You can send and receive messages from the currently loaded browser page.
A word about JavaScript
Browsers run JavaScript, specifically, ECMAScript. JavaScript has a .js extension. Unity runs .NET languages, in particular: C# (.cs), Boo (.boo), and UnityScript (.js). Due to a terrible historical mistake, UnityScript has been, and often still is, called "JavaScript". To be clear:
UnityScript IS NOT JavaScript.
In this package all references to "JavaScript" refer to what web browsers run. Beware that UnityScript and JavaScript files both have the same .js extension. In general, files in Assets/ with a .js extension will be treated as UnityScript and files in BrowserAssets/ with a .js extension will be treated as JavaScript.
Scripting Intro
Browsers have a Browser
MonoBehaviour. You can call functions in the page by invoking CallFunction
:
using ZenFulcrum.EmbeddedBrowser;
...
var browser = GetComponent<Browser>();//assuming we are a MonoBehaviour attached to the same GameObject as the Browser
//calls window.setPlayerStats("myPlayerName", 2, 4200, false) in the browser
browser.CallFunction("setPlayerStats", "myPlayerName", 2, 4200, false);
Functions are resolved in the global scope of the top frame of the browser and executed with the given arguments. You can pass basic types (strings, integers, bools, etc.) without any extra effort.
You can also use EvalJS
to run any JavaScript you'd like in the context of the page:
browser.EvalJS("if (someCondition()) someVar = 42;");
To query the page for data, you can look at the return value. EvalJS
and CallFunction
don't execute immediately, they are asynchronous, therefore they return promises:
browser.EvalJS("document.title").Then(ret => Debug.Log("Document title: " + ret));
browser.CallFunction("doSomeFoo", 1, 2, 3).Then(ret => Debug.Log("Result: " + ret));
If you are in a Unity corountine, you can wait for the promises to finish before continuing:
var promise = browser.EvalJS("document.title");
yield return promise.ToWaitFor();
Debug.Log("Document title: " + promise.Value);
This can be much easier to deal with in cases where you are chaining a lot of tasks.
See the promise section for more details on the promise library.
To receive events pushed from the page, you can expose a function callback. Do this with RegisterFunction
:
browser.RegisterFunction("confirmClicked", args => Debug.Log("Button clicked: " + args[0] + " val: " + (int)args[1]));
Then you can call it from your page:

<button onclick="confirmClicked('button3', 13)">Confirm Things</button>
Notes
- The functions that return data from a page return a
JSONNode
. This class which implicitly converts to basic types like strings and integers. Take a look in JSONNode.cs for more information. - If you'd like to pass something more complex than a basic type, build a
JSONNode
. AJSONNode
allows you to build and access JSON data using a fairly fluent language-native interface. - If you'd like to pass something yet still more complex, or have data automatically read from your objects' fields:
- You can use Unity's JSON serialization to pack and unpack data on the Unity side.
- You can use JSON.stringify/parse on the JavaScript/browser side.
- You can also evaluate raw JavaScript in the browser by calling browser.EvalJS
- If the Browser isn't ready for commands or the page isn't loaded yet, it will queue your commands and execute them then the page is loaded.
- The JavaScript execution engine is V8. Not only is JavaScript support robust and complete, you can also use some es6 features.
- Note that functions you expose won't be available at the time of the HTML load event. If you need to know when the page loads, use browser.WhenLoaded (Unity side).
- Check out the included demo and examples for some example code and use cases.
Promises
ZFBrowser uses this promise library made by Real Serious Games with some small changes.
Original documentation can be found here or online here.
This copy has been modified a bit from the version you can get from GitHub, namely:
- The library namespace has been changed from
RSG
toZenFulcrum.EmbeddedBrowser
namespace for simplicity and to avoid potential conflicts. - An
UnhandledException
handler forDebug.LogError
is registered by default. - You can use Promises with coroutines:
yield return somePromise.ForCoroutine();
waits for the promise to be rejected or resolved. - You can query a Promise for its resolved value (or rejection) with
promise.Value
.
The promise library is covered by the MIT license, as noted in ThirdPartyNoticies.txt.
Embedded Resources
You can embed web resources (HTML, JS, CSS, images, etc.) with your game and access them without the need for an external web server.
Place these resources in a folder named BrowserAssets
next to your Assets
folder, then access them with localGame://index.html
instead of the usual http://example.com/index.html
.
Notes
- localGame:// is treated like a unique domain and is subject to same-domain policies like other websites.
- Remember: If you want to run scripts on arbitrary websites, you can open a browser to that website and inject JavaScript with browser.EvalJS.
- If you want to customize or change how these resources are fetched, read the documentation in WebResources.cs.
- In the editor, you can simply refresh a page to see updated changes for changed files.
- File names are case-sensitive! Test your standalone build. Under the Editor some platforms may incorrectly load wRonGcapS successfully.
- When you build, all browser assets are packaged up as a single file and included with the build.
- localGame:// is not the actual URL the browser uses, so don't hardcode it in your HTML. (The real URL is currently
https://game.local/
, but may change.) - Avoid putting untrusted code in BrowserAssets
- You may need to URL-encode your path if it contains non-alphanumeric characters. How to encode
Input
All mouse/keyboard input events are collected in Unity and forwarded to the underlying browser. How this input is sent can be customized.
- Mouse clicks and keyboard events are fed to the Browser via the
IBrowserUI
interface. Additionally, theIBrowserUI
informs us about mouse cursor changes from the page. - This package comes with a few useful versions of
IBrowserUI
out of the box:ClickMeshBrowserUI
(used by default) - Lets you click and interact with browsers with a free mouse hovering over the scene.- Requires a mesh collider.
- It projects the mouse's position into the scene with the main camera and a physics raycast.
- UVs on the mesh collider are used to look up the "in-browser" mouse position.
- If the mouse if over the browser it is considered focused and will receive keyboard input.
- Automatically updates the mouse cursor to reflect the currently hovered area.
- Used by default, so long as the browser has a MeshCollider.
FPSBrowserUI
- Lets a first-person controlled character interact with items in a scene by walking up and pointing.- Extends
ClickMeshBrowserUI
, but:- Mouse position is inferred from the direction the camera is pointing.
- Creates a single
FPSCursorRenderer
in the scene to render the central cursor and crosshair for you.
- Attach to a browser to use it. See the demo for a working example. A prefab is also included.
- Extends
GUIBrowserUI
- For use with full-screen browsers and browsers alongside non-browser UI elements.- Operates inside a Unity UI Canvas. Renders to a RawImage and intercepts input like other UI elements.
- Drop the BrowserGUI prefab into a canvas element to use.
- You can always create your own input manager by extending one of these or by implementing
IBrowserUI
outright. Set browser.UIHandler to your custom implementation before the first call to browser.Update(). You can also set it to null, which will disable all input. - Mouse scroll speed and double-click handling options can be adjusted by altering myBrowserUI.InputSettings.
Customization
- Customize
alert()
dialogs,prompt()
dialogs,beforeUnload
dialogs and context menus by editing ZFBrowser/Resources/Browser/Dialogs.html - Customize error pages by editing ZFBrowser/Resources/Browser/Errors.html
- Hook these events by listening to
Browser.onLoadError
/onCertError
/onSadTab
.
- Hook these events by listening to
- Mouse cursors are:
- Stored in ZFBrowser/Resources/Browser/Cursors.png. (These are more-or-less the base Chromium icons.)
- Loaded and managed by the
BrowserCursor
class. - To change how a current cursor looks without altering the size, just edit Cursors.png.
- If you wish to change the cursor sizes or which cursor types map to which Cursors.png item, take a look at IconGenerator.cs. (This script isn't intended for general use, so be prepared to get your hands dirty.)
Debugging
Page Debugging
Often during development, you will find your pages need debugging.
Tip: You don't always have to restart the game to test a change, in some cases you can simply refresh the page. (Unity inspector -> browser instance -> Refresh or Page inspector -> ctrl+r).
Here's a few way to go about it:
Page Inspector
You can access the Webkit/Chromium inspector, which opens in a new window beside the running game.
- Under the Editor in play mode: Select the Browser, then click "Show Dev Tools"
- You can also use browser.ShowDevTools() to open an inspector window.
- This inspector can be a bit unstable at times. If you have issues, try a different debugging method or push Chromium out of process
External Page Inspector
You can access the page inspector from another browser.
- To debug when running in the Editor, visit http://localhost:9848/
- To debug when running a debug build, visit http://localhost:9849/
- Release builds cannot be debugged using this method.
- Use a same-version-a-the-plugin Chromium-based browser to load the above URLs.
Ordinary Browser
You can also load your pages in an ordinary browser and debug them there. If you do, you may find it useful to create small "log what happened" stubs for the functions you expose from Unity. Call functions you want to test from the JavaScript console.
Visual Studio Tools for Unity
Chromium/CEF don't play nice with Visual Studio Tools for Unity. If you want to use C# debugging with this tool, push Chromium out of process.
Chromium out of Process
Under the Windows Unity Editor we host the root Chromium process within the Unity Editor. This gives us better performance, but causes some issues such as inspector and debugger stability/usability.
If you are having issues, you can push Chromium out of the Editor process. It's a bit slower, but should be more stable for these use cases. To do this, open up BrowserNative.cs and find where PROXY_BROWSER_API
is defined. Add UNITY_EDITOR_WIN
to the list of conditions that trigger it and restart the Editor.
On OS X and Linux, the root Chromium process always runs outside the editor.
On builds, the root Chromium process always runs within your game for best performance.
Cookies
- Delete all cookies with
browser.CookieManager.ClearAll()
. - Grab the cookies from the browser with
browser.CookieManager.GetCookies()
. This is asynchronous and returns a promise, see the promise section for more information on the promise library. - Once you have a cookie, you can make edits and call
cookie.Update()
or get rid of it withcookie.Delete()
. - Create new cookies from scratch with
new Cookie(browsser.CookieManager)
adjust the fields (be sure to set at least a domain, name, and value!) then create it withcookie.Update()
. - Aside from clearing all cookies, the Cookie API is a bit experimental, in particular, the dates may not function very well.
Notes
- You can customize which browser items the user is allowed to right-click (and get a context menu on). Look in the inspector under "Allow Context Menu On". By default, only text boxes will allow a context menu.
- By default, the

of pages will be rendered as transparent. You can change to from fully transparent to any fully opaque color by changing the "Background Color" option in the inspector. The color must be changed before the firstUpdate()
. - Custom mouse cursors are supported via CSS cursors.
- You can control what happens when navigation attempts to open a new window. Change
browser.newWindowAction
to a value of your choice. If you'd like to allow opening new windows inside the game world, check out the NewWindow demo. - We use a user agent that makes most websites think we're Chrome, but it does identify the engine, library, and your application's name and version. Change your application's name and version in the Player Settings. Restart the editor to see changes.
- You can force your own user agent by calling
UserAgent.SetUserAgent(string)
. This must be called before the first browser initializes. (In the Editor you must restart to see this change; it's immutable once the first browser initializes.) - This system uses Chromium's separate process rendering architecture. It is normal to see one or more
ZFGameBrowser
child processes once a browser has been opened. - A number of events, such as page load error, are available for you to hook into. Search Browser.cs for "public event" and read the documentation above each.
- Disabling the Browser MonoBehaviour will not stop the underlying browser from running. Destroy the object or load a blank page to free up resources a page is using.
- When a browser's image changes, we re-upload the texture to the GPU. Generating mipmaps is expensive, so the included prefabs turn off mipmap generation and use a special mipmap-emulating shader that "fakes" a texture with mipmaps, keeping ugly pixelation at bay for a minimal cost. Check out the Materials/EmulatedMipmap folder.
- You can adjust the command-line switches sent to Chromium by fiddling with
BrowserNative.commandLineSwitches
. Read the comment above it in BrowserNative.cs for instructions.
Latency/Performance
The browser is rendered offscreen in a separate process and the resulting pixels are transferred to a texture. Performance will not be as good as native Chromium, but should be fine when using either small textures or minimal animation.
Latency:
- All activity (mouse clicks, JS calls, input) is sent asynchronously to a separate renderer process and the results are asynchronously reported back. As such, there is a short delay between when a command is issued and when the results are visible. The delay should be quite reasonable in most cases, but don't expect results the same frame you issue a command.
- Avoid using a Browser for latency-critical use cases such as rhythm games, world-aligned HUD markers, and rendering mouse cursors.
Performance:
- Try to use small (texture size) Browsers for animations and things that frequently update. Large sizes are more suitable for static displays and user interfaces.
- Frame updates for large (resolution) browsers are expensive. Often the final image is composited on the GPU, pulled back to the CPU, then pushed to the GPU again from a different process. Depending on the hardware, size of texture, and frequency of updates, this can impact framerates poorly.
- Remember that on almost all systems the browsers use the same GPU for rendering that Unity does. If you have heavy content, be sure to factor this into your rendering budget.
Adobe Flash
This version of ZFBrowser includes experimental support for Adobe Flash. Enabling it requires some extra steps.
Do I need it?
The Web is an evolving place and ever-increasingly interactive web sties don't need Flash to support media-rich content.
You need Flash if you want to:
- Display content that is only available with Flash.
- Watch video that uses proprietary codecs, such as h.264. ZFBrowser doesn't have licenses for these codecs, but Flash does and many video streaming sites will fall back to using a Flash player to stream content if necessary.
For myself (manual install)
If you are developing locally, prototyping, or will only distribute your application to computers that you control, use this method.
Instructions:
- Install the Adobe Flash Player on your system.
- Go to https://get.adobe.com/flashplayer/otherversions/
- Select your OS
- Select the latest "PPAPI" version available.
- Uncheck boxes for things you don't want.
- Download now.
- Install using the usual methods for your OS.
- Open up BrowserNative.cs
- Under
commandLineSwitches
add--enable-system-flash
- Under
- Go! (You may need to restart the Editor.)
You'll need to install Flash on every computer you distribute your application to.
For anyone (distribute Flash)
To distribute Flash with your application, you'll need to get permission from Adobe and run their installer with your installer.
General flow: Untested, let me know how it goes!
- Start development using the instructions in the last section, including the
--enable-system-flash
flag. - Get a distributor's license for your application
- Apply here
- Fill out paperwork, get approval from Adobe.
- Get an installer from Adobe. You need the PPAPI version (for Chromium).
- Set up the Flash installer to run when your application installs.
Known issues
- Support for the inspector is experimental, it can be unstable at times.
- Support for Flash is experimental. Sometimes a command prompt window may flash while starting Flash content.
- On occasion the editor may crash/hang when closing/switching projects or opening pop-up windows.
Ideas
- Build your complicated crafting UI in HTML
- Replace your HUD with a browser page
- Door access/control panels
- In-game billboard advertisements

Downscaling module¶
Overview¶
High resolution crop allocation datasets are not usually available in open access sources. In principle, ‘downscaling models’ use high-resolution input data (e.g. in our case temperature, precipitation, soil pH etc.) which have predictive power over low-resolution input data (e.g. in our case national or admin level aggregate values of harvested area, production etc.).
In order to do so, we have used the Fine Scale Land Allocation Tool or FLAT model. FLAT is a statistical-based open access tool that combines dependent variable data measured at an aggregate level (e.g., state/provincial or national) with independent variable data measured at the pixel level to produce estimates of the dependent variable at the pixel level.
Input data preparation¶
In terms of the dependent aggregate values of harvested area, we have used FAO Agro MAPS Global Spatial Database of Agricultural Land use Statistics. The database provides agricultural statistics and data collected and compiled from national resources, surveys, and official in-country agencies, assuring some degree of consistency across different agricultural products and geographic areas. This consistency is considered highly important in this exercise as it allows replicability to other regions or agricultural products.
For the purposes of this exercise, level 2 administrative crop data were used as shown in Figure below.
Note
In case input data is outdated, they will need to be projected to the base year. For example in this case the total harvested area for maize was equal to only 782,608 ha in 2008 (input data), while 2017-18 FAO estimates indicate about 1,962,000 ha in Mozambique. This can be done through a python script available as Preparing Agro Maps.
Then, the above dataset is transformed into a base (vector) layer at the targeted downscaling resolution (e.g. 1km). This is used later on to extract the predictor attributes per location. The steps for this are as follows:
- Project crop layer to target crs (in this case EPSG: 32737 – WGS 84/UTM zone 37S )
- Calculate “area” in sq.km and “perimeter” in km for listed admin areas
- Convert “area” from sq.km to ha
- Create the base grid mesh (10km, 5km, 1km, 500m or 250m)
- Only keep locations where harvested area for the listed crop is available.
- Convert polygons to centroids indicating the location of crops at the selected resolution.
- Export output as a .csv file
Note
In order to facilitate the process, we have developed a QGIS plugin that together with instructions for installation and use is available at the project’s repository.
Finally, once base (vector) data layer is ready and available as a .csv file, predictor values are extracted from raster layers. As predictors in the FLAT model, we may use the following variables:
- Average temperature
- Average solar irradiation
- Average precipitation
- Average wind speed
- Soil Ph in H20
- Depth to bedrock
- Bulk density
- Clay content
- Texture class
- Soil organic carbon
- Drainage class
- EVI
- NDVI
- Elevation - Slope
- Cropland extent
The extraction process yields a .csv file that serves as input to the FLAT model. An example of this file is available as FLAT_input_Maize_10km.
Note
All of the above data can be collected either in their raw format or using a Python script (GEE_Imagery_Extraction) that was developed specifically for the extraction of the Images and ImageCollections using the GEE API.
Note
- The extraction process can be conducted through code available as FLAT prepping in the project’s repository.
- With regards to the imported geospatial layers (both raster and vector files), each one should be re-projected into the same coordinate system e.g. EPSG: 32737 – WGS 84/UTM zone 37S (+proj=utm +zone=37 +south +datum=WGS84 +units=m +no_defs) for Mozambique.
Parameterization & model run¶
The FLAT model can be executed with the following steps.
Step 1. Go to directory:
>/ FLAT_model/src
Step 2. In the directory run:
>/ Rscript RforFLAT.R flat_input.csv 0.534 1 15
where:
- flat_input.csv is the output csv of FLAT prepping process
- 0.534 is the target spatial resolution in arc.min
- 1 is the number of modelled crops
- 15 is the number of independent variables
Note
This process requires R to be installed at your working station. Running the above script creates nine derivative .csv files that are needed in Step 3. These include cropnames, pixels, states, data, statelevelcroparea, name, pixelarea, statelevelareainfo and variables.
Step 3. Copy the nine .csv files into the resource directory:
>/ FLAT_model/src/resource
Note
FLAT.gms should be located in the same directory as well - default by installation.
Step 4. Open GAMS Terminal; move to resource directory and run:
>/ gams FLAT.gms
Note
This will run FLAT model. Once complete, the log file (FLAT.ist) will be generated. This can be used to monitor the specifics of the run and track any issue in the debugging process (if needed). The result file is a .dat file usually under the name “finalresults.dat”. Other output files might include “Pixel-level cropland predictions against FAO aggregate values”; “Coefficient estimates”; ”Standard error”; “Covariate matrix for parameter estimation”.
Step 5. Export results (Optional)
>/ FLAT_model/src
run > Rscript dattotiff.R maize finalresults.dat (to generate a raster file (.tiff) of the results) or
run > Result.r (to export results in .csv format)
Note
Transformation of the result (.dat) file into a .csv file that can later on be used for the irrigation model can also be conducted using the script Dat to csv.
Output data¶
The output file provides a prediction the downscaled crop allocation. Each location (point in the vector layer) is attributed with a fraction of the total harvested area of the admin level it belongs to. Aggregation of the downscaled results per admin layer sum up to the original values.
Special notes¶
The downscaling process is a good – yet experimental – way to achieve higher granularity of crop distribution, especially in areas where there is data scarcity.
The FLAT model that was selected in this assignment is open source (although GAMS is needed for big datasets) and straightforward to test, use and customize. It predicts cropland allocation using pixel-level biophysical attributes which are openly available at the desired spatial resolution (1 km). The econometric approach provides estimates of the effects of biophysical factors on cropland allocation.
FLAT performance metrics are in alignment with available literature; visual inspection of results does also agree with qualitative findings from sample agricultural survey. However, the selected cross-validation approach highlighted that inconsistencies in the sample dataset are high to achieve any satisfactory results. This highlights the need for standardization of collection, processing and dissemination of survey related datasets.
Note
A first and second order validation process was conducted in this project and is available in the project report. This was implemented through a Python script available as CrossValidation.

Ruby's Enumerable Methods
Sunday, November 22, 2015
What is an enumerable?
In Ruby, you can iterate through each element in a class like the array, hash, set, and range collection classes using the #each method. These classes have defined the #each method, so they can mixin the "Enumerable" module. Methods in the "Enumerable" module allow you to iterate through the elements in a collection and do something to each element in the collection. This means you can just use an enumerable method that helps you do something you specifically want to do to each element in a collection.
What are some enumerable methods?
- #each_slice: iterates through n elements in a collection
- #map: modifies each element according to a block's conditions and returns a new array with the modified elements
- #find_all: returns an array containing all the elements that returned a true value from the conditions in a block
- #group_by: takes a block and returns a hash that groups all the different types of returns from the block
How can I use the #group_by method?
The #group_by method seems to be a pretty handy and awesome method, so here are some ways to use the method.
#group_by with a Range
Let's say you wanted to know how many times each number in a range from 1 to 20 was divisible by 4. After running the #group_by method on the range it will return a hash with the keys 0, 1, 2, 3, 4, and 5. The values for each key in the hash will be an array of values that returned 0, 1, 2, 3, 4, or 5 when divided by 4.
#group_by with an Array
If you had an array listing the names of people you could group the names by the length of the string.
#group_by with a Hash
Since the holidays are just around the corner, maybe you've used a hash to list of all the people you need to buy a gift for and whether you've done so. You could use the #group_by method to help shorten your list to just the people you haven't purchased a gift for.

Dark Souls Trilogy, Code Vein, Kingdom Hearts and more top console games for £30 or less
Praise the sun!
Deals by James Pickard, Commerce Editor Updated on 13 November 2019
At the risk of showing my age here, remember when console games launched at £30? What a time to be alive. Well, in an attempt to replicate that feeling for you, I've gathered up a number of top console games that are now at that price or less. Ah, yes, it feels just like the good old days already!
Let's start things off with the Dark Souls Trilogy, which has fallen to its lowest ever price on PS4 at £29.99. Because why have just one tough-as-nails RPG when you can have three? I say good luck to you if you try to play all three back-to-back!
Sticking on a similar theme, you can also get Code Vein on PS4 and Xbox One for £29.99. The influence of the Souls series on this Bandai Namco action-RPG is unmistakable, with Edwin calling it "anime Bloodborne with added buddy bonding". A decent shout, then, if you've mastered From Software's entire back catalogue and are itching for something similar.
For an RPG that isn't going to be quite as punishing but no less gruelling in terms of length, you can get the Kingdom Hearts All-In-One Package for £29.69 from the PSN Store. This version comes with every single game in the Kingdom Hearts series so far, with all their unnecessarily complex subtitles. I'll see you in a few hundred hours.
I've got a few more possibilities for you below too, all of which I'd easily recommend at these prices. Some could make a good treat for yourself now or tick off something on your Christmas gift list.
- Spider-Man on PS4 for £20.85 from Base
- Spider-Man: Game of the Year Edition on PS4 for £28.99 from Base
- Assassin's Creed Odyssey Gold Edition on PS4 for £29.99 from 365 Games
- Grand Theft Auto 5: Premium Edition on PS4 for £18.99 from Amazon UK
- Grand Theft Auto 5: Premium Edition on Xbox One for £18.99 from Amazon UK

- Resident Evil 2 on Xbox One for £19.99 from Amazon UK
- Devil May Cry 5 on PS4 for £19.99 from Amazon UK
- Devil May Cry 5 on Xbox One for £14.85 from Base
Definitely some great prices there. You can expect more of this to come over the next few weeks as we enter the chaotic Black Friday sales period. We're already tracking all the best PS4 Black Friday, Nintendo Switch Black Friday and Xbox Black Friday deals currently available. Keep checking in on those pages as they'll be regularly updated throughout the month.

You may have noticed that in the statement we added during the last step, there was a parameter marker to which we did not have any corresponding parameters set to replace it with. Although statements are processed in the order in which they appear, in this case the parameters are set up such that the substitution will take place on the server side.
To do this you will need to change the type of the parameter 'SQL' to 'raw' and add a new parameter at the bottom to send the task ID to the server.
Note: This is not a bind parameter marker in a prepared statement but a text substitution of the parameter marker.

Regular Expression
//Test Strings
Scriptular is a javascript-based regular expression editor.
Before the summer of 2011 I never took the time to dig into regular expressions and actually learn how they work. Then Hubot came along and suddenly regular expressions were cool.
Immediately I began writing hubot scripts and started using Rubular to test my regular expressions. Unforunately there are some differences between Ruby's regular expressions and the myriad of implementations in javascript (and specifically the V8 implementation that hubot uses), so I needed a new Rubular, one for javascripts.
So I created Scriptular and started regular expressing myself ;) This is a beta, probably has a ton of bugs, but you have to start somewhere. Also, since it uses your browsers javascript interpreter there will be differences between your results here and other browsers and even V8, so this is not necessarily the perfect editor for regular expressions in hubot.
Having said that, I hope someday to have a V8 option to run against so you can write perfect regular expressions for hubot everytime.

THE GAME
Set in a moles burrow, players must fight off waves of oncoming zombie badgers,
completing mini-games to unlock doors and revive players. The badgers are hungry for
moles, and they are relentless in their hunt for blood.
MoleZ is a twin stick wave survival game inspired by games such as Call of Duty:
Zombies and Minigore. The game uses the players smartphone as a controller, allowing
for interesting mini-games and making co-op games with your friends even easier. The
objective of the game is to survive to as high a wave as possible, unlocking rooms and
even an upgrade shop as you make your way through the level.
MoleZ Gameplay
The 4 playable characters
The main MoleZ game is developed to run on PC or Mac, and the controller app has
been developed to run on any Android smartphone. This game was made as my final year project of a Ba(Hons) Game Design degree.
The game and app were both built using Unity development software, as I have the
most experience with using this software. The game uses Unity’s (now deprecated)
networking system, specifically the high-level API, to connect the mobile devices to the
main game. The main game runs as a multiplayer server, and the smartphones connect
directly as clients. Due to this, the controllers must be on the same network as the main
game to allow a successful connection. A direct connection allows messages to be sent
between the clients and server at high speed, with almost no latency on a high-quality
connection.
USING A PHONE AS A CONTROLLER
The game is based around the idea of using a smartphone as a controller for a larger game, which has many benefits but also
a few drawbacks. Taking these into full consideration, MoleZ manages to create an intuitive and responsive experience that
allows the player to forget they're using a phone as a controller. A few of the benefits and drawbacks are outlined below.
BENEFITS
-
Most people own a smartphone, so
playing co-op games with your friends is
even easier.
-
Content on the controller can be changed
to reflect in game scenarios and each
player can have their own unique
content/control scheme.
-
Game can make use of the phones
accelerometer to allow motion controls.
-
A touch screen allows for different types
of input other than buttons, such as
swipes or pinches.
DRAWBACKS
-
No tactile feedback when pressing
buttons, so can be hard to find specific
buttons without looking at the screen.
-
Slight latency when inputting button
presses.
-
Phone batteries deplete a lot quicker
than a standard controller
-
Different phone screen sizes and
operating systems make it hard to
develop a single control scheme that
works across all devices
The main phone control screen
PHONE MINIGAMES
One of the main ideas behind the concept of MoleZ was the ability to use the smartphone to have minigames that are ran on the smartphone
controller that affect the main game in some way. I initially planned to have more varied minigames, but as a POC, the two I created make use of
the possibilities of the phone in creative ways. The first minigame the players encounter is when they would like to clear the way to open up new areas of the map.
This minigame involves looking at the screen and timing when to press the button to break all the rocks. Due to the way this is designed, it means that the player
has to divert attention away from the main game and risk taking damage, to instead focus on the screen of their smartphone. This game scales in difficulty as more doorways
are opened.
The door opening minigame
Solo reviving minigame.
The second minigame is used to revive players. If it is a multiplayer game, then the player who is downed and needs reviving has a prompt appear on their
screen. Their phone vibrates, similar to a heartbeat, with a random interval. It is then up to them to communicate with the other player
what the specific rhythm is, as the player who is reviving them has to move their phone in a CPR fashion in time with their heartbeat. This
forces communcation between the players, and brings the game out of the screens and into the real world, taking advantage of the possibilities of the smartphone controller. For players who might have vibration disabled, a visual prompt is also
displayed.
OTHER FEATURES
The game also features other mechanics that are usually found in games of this genre, such as temporary and permanent powerups, an upgrade shop, and boss zombies.
Permanent upgrade

which allows you to use Unity's built in navigation system in 2D projects.
DOWNLOAD AND PLAY
The zip files below contain the executables for the Windows and Mac versions of the main game, and the .apk file for the android controller app. Unfortunately, as I do not own a mac,
I cannot develop or publish the app for iPhone/iPad.

Resilience is by design - How?
isolation (decoupling, both in time and space)
- in time: sender and receiver don't need to be present at the same time for communicate

Bulkheads help us to:
isolate the failure
compartmentalize
manage failure locally
avoid cascading failures

PROBLEM - Example Situation
web app interacting with a remote WS
remote WS is overloaded, and its DB takes a long time to respond with a fail
=> WS calls fail after a long period of time
=> web users noticed that form submissions takes time to complete
=> web users start to click the refresh button adding more requests!
=> web app fails due to resource exhaustion, affecting all users across the site
failures in external dependencies shouldn' t bring down an entire app
Circuit Breaker
Solution Proposal
monitor response times
if time consistently rises above a threshold, either:
fail fast approach, or...
route following requests to an alternative service
monitor the original service
if the service is back in shape, restore to the original state
if not, continue with the same approach

The AppConfig Spec Creator is a tool that assists iOS App Developers (ISVs) in the creation of “Spec Files” that describes the settings that are available in their apps. Enterprise Mobility Management vendors (EMMs) can then utilize these “Spec Files” to expose intuitive user interfaces to IT Professionals that are deploying iOS apps throughout their enterprise.

Here is the latest data on “the business of education” for November 2017:
I debated whether or not two very large investments this month should be included in my calculations: $500 million invested in WorldStrides, an accredited student travel company, and $400 million invested in UBTech, a robotics company. The latter says its robots have entertainment and educational functions, but I just couldn’t see enough of the latter in their marketing material to justify their inclusion. The former I have included, even though people will complain “that’s not ed-tech.” When venture capitalists and private equity are interested in a concept, we’re better off paying attention than pretending like a strict definition of “learning technologies” matter.
That $500 million boosts the amount of money invested so far this year much much higher than the two previous years – the amount of time I’ve been keeping track of the details of funding. Even so, the number of investment deals has fallen – there are five fewer deals than this time last year and nineteen fewer than in 2015. The growth in funding continues to be driven this year by a small number of very large investments. (There were three investments this month of $40 million or more.)
Acquisitions continue to be down from previous years – off by ten from last year and twenty from 2015. There have been a number of IPOs this year – the other way that investors can get a return on their money – but these have been almost exclusively by Chinese education companies
The companies that have raised the most money in 2017 (not including the venture capital firms that have raised new funds):
I’ll have much more to say about venture capital and venture philanthropy as part of my annual review of the year in ed-tech. In the meantime, you can review who’s received funding, who’s been acquired, who’s IPO’d, which startups have closed, and who’s investing in the stories that Edsurge tells you about the shape of the education technology industry.
I have created separate GitHub repositories for all areas of funding that I monitor:
These sites include human- and machine-readable versions of this funding data. For more ed-tech data sets, visit Hack Education Data on GitHub.
If you see an error or omission, please file a GitHub issue. You’re welcome to fork or download the repositories too, of course.
