Pinebook Pro Follow-up: Manjaro Linux
I had written in early February about my Pinebook Pro laptop after roughly a month of using it. Now that significantly more time has passed, time which I’ve almost exclusively spent at home due to nationwide stay-at-home orders and social distancing, I figure I’d share some of my thoughts on the laptop I raved about initially, and more specifically what I’ve done with the operating system.
The OS⌗
If you read my original post then you may recall that I was debating swapping the default Debian operating system for something different. While I mentioned NetBSD in the post I ended up installing Manjaro Linux instead. Why? There are a few reasons to consider.
One of the biggest reasons why swapping the OS can be considered important is that there are some issues with the Debian build that came on my device. It’s a custom setup put together by a community member. It looks incredible, but that comes at a cost; the highly customized environment means that many things in it cannot be updated; this includes both Chromium and Firefox. Running outdated browsers isn’t exactly cool, and I wasn’t too keen on having to compile Firefox from source every time there was a new release.
On the other hand many of the community members seemed to really love Manjaro Linux, so I figured I’d gvie it a shot. Along with people in the Pinebook community raving about it, it’s also been hovering near the top of Distrowatch for a while now. In fact it was announced in March that Manjaro was going to be the default OS for new Pinebook Pro devices, which is pretty slick! They’re shipping with the KDE variant, though, and while I’ve read about people having a good experience with that, I personaly prefer the more lightweight XFCE desktop. It’s lighter, simpler, and overall I feel like it’s a better fit for the Pinebook Pro.
Getting The OS⌗
As something of a noob when it comes to working with open source SoC setups like a Rock64 or Raspberry Pi, I struggled a little with figuring out exactly how to install a new OS on the Pinebook Pro. The first thing I figured out is that, currently, you cannot boot the Pinebook Pro from USB. I made a few bootable flash drives like I would’ve historically used when installing Linux on a more traditional device without success. The Pinebook Pro wiki seems to contradict itself on this point, saying:
The Pinebook Pro is capable of booting from eMMC, USB 2.0, USB 3.0, or an SD card. It cannot boot from USB-C. The boot order of the hard-coded ROM of its RK3399 SoC is: SPI NOR, eMMC, SD, USB OTG.
Then in the very next paragraph it says:
At this time, the Pinebook Pro ships with a Debian + MATE build with uboot on the eMMC. Its boot order is: SD, then eMMC. Booting off USB storage is not currently available, but will be in the future.
I wouldn’t put it past myself to just be misunderstanding something, though, so your mileage may vary. As you might be able to guess from the quotes shared above, I just ordred a cheap microSD card online and used that for the OS installation; everything worked great.
For Manjaro specifically, the best way to get the proper image is to go to the forum announcement for the latest version, like this one for the 20.04 release. There you can select the appropriate link for your Pinebook Pro and for your preferred desktop environment. Once you select that, you’ll be taken to another page like this one listing all of the images files you can download for that version and desktop environment.
Be aware that if you want to install Manjaro directly on the laptop, be sure to grab the image file with “emmc-installer” in the file name! This is the image designed to be flashed onto the internal eMMC storage of the Pinebook Pro! Grabbing the image without this will simply create a microSD card that will run the OS. This isn’t bad if you’d like to try out Manjaro while leaving the Debian installation on your eMMC, but I wanted to go all-in.
Preparing Your Media⌗
To prepare the media, you can use basically any option that’ll allow you to flash the .img file you downloaded onto the microSD card. You can be old-school and use dd
from the command line, but I went easy mode and used balenaEtcher instead.
The Rest⌗
The boot order on the Pinebook Pro automatically has the microSD card slot above the eMMC, so once you have a microSD card prepared just insert it into the Pinebook Pro, boot the device, and follow the prompts; it’s honestly pretty simple to install. The only catch is a known bug with the 20.04 release where you have to hit Esc
while looking at the Manjaro logo after booting from the microSD card before it’ll move forward; as a known bug I would imagine this won’t be relevant for future releases.
When the Manjaro logo has been present for about 15 seconds, press ESC (this is a bug, we know).
Once it’s all done, you boot to this gorgeous view!
Caveats⌗
For the most part, Manjaro works like a complete dream, and I’ve been extremely happy with it. There are just a couple of caveats that might be worth mentioning, though.
Initial Update⌗
First, there was a bug when running the initial software update on the factory image. First I had to figure out how to update it, but after some quick DuckDuckGo-fu (since I’ve really only used Debian-based flavors of Linux before) I figured I could update Manjaro via:
sudo pacman -Syyu
Note that you can aslo just click the little shield icon in the bottom-right corner of the screen. Regardless of method, though, immediately after booting my new OS I would get the following error when attempting to update:
Conflicting files: nss /usr/lib/p11-kit-trust.so already exists in filesystem
Another benefit to choosing Manjaro is that it has an extremely active community, so it’s easy to search on errors like this and get solutions! I quickly found a YouTube video covering this error and providing the solution:
sudo pacman -Syyu --overwrite /usr/lib*/p11-kit-trust.so
After that initial update succeeded I’ve been able to perform subsequent updates without needing the --overwrite
parameter. Updating via the GUI also works.
Swap⌗
It’s entirely possible I just made a mistake in my installation, but I eventually realized that I didn’t have a swap partition or file. I realized this because I noticed that the battery drain while under suspend was a bit severe; I was losing roughly 6% of my battery per hour. This meant that leaving the device on suspend for a day would completely drain a full battery. I changed my XFCE setting so that when closing the lid of the device it would hibernate. This gave me an error, though, that I didn’t have enough swap space to hibernate.
I checked the output of htop
and realized that I didn’t have enough space because I didn’t have any swap. Luckily for me, the Manjaro folks have a wiki page dedicated to exactly this; I ended up following the steps to create a swapfile rather than adjusting my partitions to have a swap partition. Since there are 4 GB of RAM in the Pinebook Pro, I ended up creating a 4 GB swap file. Once it’s created you can verify it by looking at htop
or running swapon
. If you’re concerned about the amount of storage on the eMMC, you can see how much you’re using via:
df -H | grep /$
Typing and the Touchpad⌗
One thing I’ve noticed on occasion is that typing does not disable the touchpad on the laptop, meaning that it’s easy for your hand to accidentally brush it, clicking somewhere else and causing a bit of havoc on whatever it is you’re trying to do. I’ve accidentally done it once just while working on this article. I’ve not found a solution for this yet (I’ll update the post if I do), but it hasn’t been a big deal for me. It’s just something to be mindful about.
The End⌗
On the whole, I’m extremely pleased with my switch to Manjaro. If you’re running a Pinebook Pro with the original Debian build, I’d highly recommend giving Manjaro a shot; it honestly feels like a whole new device afterward.
Keep the open source love alive, and stay pink!

Team members now have the opportunity to concentrate on their primary mission rather than taking time to perform administrative tasks. Wizards also provide relief to IT teams burdened with user requests for workspace configuration and management.
Security and compliance
The need for security and compliance must be weighed against the ability for users to have quick access to information. With Xythos’ comprehensive document management security, organizations control who can access content and who can access individual folders and documents. This approach enables all documents to be filed in one place, providing a complete, unified view of content, documents and records.
Whether organizations are implementing practices to help ensure continued corporate compliance, improve electronic audits, or are merely looking for tools to help facilitate an initial round of compliance measures, Enterprise Document Manager helps meet stringent compliance requirements. Here are just a few of the security and compliance features within Enterprise Document Manager:

Antiracism is a favorite concept on the American left these days. Of course, all good sorts want to be against racism, but what does the word mean exactly?
The contemporary discourse of “antiracism” is focused much more on taxonomy than politics. It emphasizes the name by which we should call some strains of inequality—whether they should be broadly recognized as evidence of “racism”—over specifying the mechanisms that produce them or even the steps that can be taken to combat them. And, no, neither “overcoming racism” nor “rejecting whiteness” qualifies as such a step any more than does waiting for the “revolution” or urging God’s heavenly intervention. If organizing a rally against racism seems at present to be a more substantive political act than attending a prayer vigil for world peace, that’s only because contemporary antiracist activists understand themselves to be employing the same tactics and pursuing the same ends as their predecessors in the period of high insurgency in the struggle against racial segregation.
This view, however, is mistaken. The postwar activism that reached its crescendo in the South as the “civil rights movement” wasn’t a movement against a generic “racism”; it was specifically and explicitly directed toward full citizenship rights for black Americans and against the system of racial segregation that defined a specific regime of explicitly racial subordination in the South. The 1940s March on Washington Movement was also directed against specific targets, like employment discrimination in defense production. Black Power era and post-Black Power era struggles similarly focused on combating specific inequalities and pursuing specific goals like the effective exercise of voting rights and specific programs of redistribution.
Clarity lost
Whether or not one considers those goals correct or appropriate, they were clear and strategic in a way that “antiracism” simply is not. Sure, those earlier struggles relied on a discourse of racial justice, but their targets were concrete and strategic. It is only in a period of political demobilization that the historical specificities of those struggles have become smoothed out of sight in a romantic idealism that homogenizes them into timeless abstractions like “the black liberation movement”—an entity that, like Brigadoon, sporadically appears and returns impelled by its own logic.
Ironically, as the basis for a politics, antiracism seems to reflect, several generations downstream, the victory of the postwar psychologists in depoliticizing the critique of racial injustice by shifting its focus from the social structures that generate and reproduce racial inequality to an ultimately individual, and ahistorical, domain of “prejudice” or “intolerance.” (No doubt this shift was partly aided by political imperatives associated with the Cold War and domestic anticommunism.) Beryl Satter’s recent book on the racialized political economy of “contract buying” in Chicago in the 1950s and 1960s, Family Properties: Race, Real Estate, and the Exploitation of Black Urban America, is a good illustration of how these processes worked; Robert Self’s book on Oakland since the 1930s, American Babylon, is another. Both make abundantly clear the role of the real estate industry in creating and recreating housing segregation and ghettoization.
Tasty bunny
All too often, “racism” is the subject of sentences that imply intentional activity or is characterized as an autonomous “force.” In this kind of formulation, “racism,” a conceptual abstraction, is imagined as a material entity. Abstractions can be useful, but they shouldn’t be given independent life.
I can appreciate such formulations as transient political rhetoric; hyperbolic claims made in order to draw attention and galvanize opinion against some particular injustice. But as the basis for social interpretation, and particularly interpretation directed toward strategic political action, they are useless. Their principal function is to feel good and tastily righteous in the mouths of those who propound them. People do things that reproduce patterns of racialized inequality, sometimes with self-consciously bigoted motives, sometimes not. Properly speaking, however, “racism” itself doesn’t do anything more than the Easter Bunny does.
Yes, racism exists, as a conceptual condensation of practices and ideas that reproduce, or seek to reproduce, hierarchy along lines defined by race. Apostles of antiracism frequently can’t hear this sort of statement, because in their exceedingly simplistic version of the nexus of race and injustice there can be only the Manichean dichotomy of those who admit racism’s existence and those who deny it. There can be only Todd Gitlin (the sociologist and former SDS leader who has become, both fairly and as caricature, the symbol of a “class-first” line) and their own heroic, truth-telling selves, and whoever is not the latter must be the former. Thus the logic of straining to assign guilt by association substitutes for argument.
My position is—and I can’t count the number of times I’ve said this bluntly, yet to no avail, in response to those in blissful thrall of the comforting Manicheanism—that of course racism persists, in all the disparate, often unrelated kinds of social relations and “attitudes” that are characteristically lumped together under that rubric, but from the standpoint of trying to figure out how to combat even what most of us would agree is racial inequality and injustice, that acknowledgement and $2.25 will get me a ride on the subway. It doesn’t lend itself to any particular action except more taxonomic argument about what counts as racism.
Do what now?
And here’s a practical catch-22. In the logic of antiracism, exposure of the racial element of an instance of wrongdoing will lead to recognition of injustice, which in turn will lead to remedial action—though not much attention seems ever given to how this part is supposed to work. I suspect this is because the exposure part, which feels so righteously yet undemandingly good, is the real focus. But this exposure convinces only those who are already disposed to recognize.
Those who aren’t so disposed have multiple layers of obfuscating ideology, mainly forms of victim-blaming, through which to deny that a given disparity stems from racism or for that matter is even unjust. The Simi Valley jury’s reaction to the Rodney King tape, which saw King as perp and the cops as victims, is a classic illustration. So is “underclass” discourse. Victimization by subprime mortgage scams can be, and frequently is, dismissed as the fault of irresponsible poor folks aspiring beyond their means. And there is no shortage of black people in the public eye—Bill Cosby and Oprah Winfrey are two prime examples, as is Barack Obama—who embrace and recycle those narratives of poor black Americans’ wayward behavior and self-destructive habits.
And how does a simple narrative of “racism” account for the fact that so many black institutions, including churches and some racial advocacy organizations, and many, many black individuals actively promoted those risky mortgages as making the “American Dream of home ownership” possible for “us”? Sure, there are analogies available—black slave traders, slave snitches, “Uncle Toms” and various race traitors—but those analogies are moral judgments, not explanations. And to mention them only opens up another second-order debate about racial authenticity—about who “really” represents the black community. Even Clarence Thomas sees himself as a proud black man representing the race’s best interests.
My point is that it’s more effective politically to challenge the inequality and injustice directly and bypass the debate over whether it should be called “racism.”
I do recognize that, partly because of the terms on which the civil rights movement’s victories have been achieved, there is a strong practical imperative for stressing the racially invidious aspects of injustices: they have legal remedies. Race is one of the legal classes protected by anti-discrimination law; poverty, for instance, is not. But this makes identifying “racism” a technical requirement for pursuing certain grievances, not the basis of an overall political strategy for pursuit of racial justice, or, as I believe is a clearer left formulation, racial equality as an essential component of a program of social justice.
Anti-Marx
I’ve been struck by the level of visceral and vitriolic anti-Marxism I’ve seen from this strain of defenders of antiracism as a politics. It’s not clear to me what drives it because it takes the form of snide dismissals than direct arguments. Moreover, the dismissals typically include empty acknowledgment that “of course we should oppose capitalism,” whatever that might mean. In any event, the tenor of this anti-Marxism is reminiscent of those right-wing discourses, many of which masqueraded as liberal, in which only invoking the word “Marxism” was sufficient to dismiss an opposing argument or position.
This anti-Marxism has some curious effects. Leading professional antiracist Tim Wise came to the defense of Obama’s purged green jobs czar Van Jones by dismissing Jones’s “brief stint with a pseudo-Maoist group,” and pointing instead to “his more recent break with such groups and philosophies, in favor of a commitment to eco-friendly, sustainable capitalism.” In fact, Jones was a core member of a revolutionary organization, STORM, that took itself very seriously, almost comically so.
And are we to applaud his break with radical politics in favor of a style of capitalism that few actual capitalists embrace? This is the substance of Wise’s defense.
This sort of thing only deepens my suspicions about antiracism’s status within the comfort zone of neoliberalism’s discourses of “reform.” More to the point, I suspect as well that this vitriol toward radicalism is rooted partly in the conviction that a left politics based on class analysis and one focused on racial injustice are Manichean alternatives.
Devolutions
This is also a notion of fairly recent provenance, in part as well another artifact of the terms on which the civil rights victories were consolidated, including the emergence of a fully incorporated black political class in the 1970s and its subsequent evolution. By contrast, examining, for example, the contributions to historian and civil rights activist Rayford Logan’s 1944 volume What the Negro Wants, one sees quite a different picture. Nearly all the contributors—including nominal conservatives—to this collection of analyses from a broad cross section of black scholars and activists asserted in very concrete terms that the struggle for racial justice and the general struggle for social and industrial democracy were more than inseparable, that the victory of the former largely depended on the success of the latter. This was, at the time, barely even a matter for debate: rather, it was the frame of reference for any black mass politics and protest activity.
As I suggest above, various pressures of the postwar period—including carrots of success and sticks of intimidation and witch-hunting, as well as the articulation of class tensions within the Civil Rights movement itself—drove an evolution away from this perspective and toward reformulation of the movement’s goals along lines more consonant with postwar, post-New Deal, Cold War liberalism. Thus what the political scientist Preston Smith calls “racial democracy” came gradually to replace social democracy as a political goal—the redress of grievances that could be construed as specifically racial took precedence over the redistribution of wealth, and an individualized psychology replaced notions of reworking the material sphere. This dynamic intensified with the combination of popular demobilization in black politics and emergence of the post-segregation black political class in the 1970s and 1980s.
We live under a regime now that is capable simultaneously of including black people and Latinos, even celebrating that inclusion as a fulfillment of democracy, while excluding poor people without a whimper of opposition. Of course, those most visible in the excluded class are disproportionately black and Latino, and that fact gives the lie to the celebration. Or does it really? From the standpoint of a neoliberal ideal of equality—in which classification by race, gender, sexual orientation or any other recognized ascriptive status (that is, status based on what one allegedly is rather than what one does) does not impose explicit, intrinsic or necessary limitations on one’s participation and aspirations in the society—this celebration of inclusion of blacks, Latinos and others is warranted.
We’ll be back!
But this notion of democracy is inadequate, since it doesn’t begin to address the deep and deepening patterns of inequality and injustice embedded in the ostensibly “neutral” dynamics of American capitalism. What A. Philip Randolph and others—even anticommunists like Roy Wilkins—understood in the 1940s is that what racism meant was that, so long as such dynamics persisted without challenge, black people and other similarly stigmatized populations would be clustered on the bad side of the distribution of costs and benefits. To extrapolate anachronistically to the present, they would have understood that the struggle against racial health disparities, for example, has no real chance of success apart from a struggle to eliminate for-profit health care.
These seem really transparent points to me, but maybe that’s just me. I remain curious why the “debate” over antiracism as a politics takes such indirect and evasive forms—like the analogizing and guilt by association, moralistic bombast in lieu of concrete argument—and why it persists in establishing, even often while denying the move, the terms of debate as race vs. class. I’m increasingly convinced that a likely reason is that the race line is itself a class line, one that is entirely consistent with the neoliberal redefinition of equality and democracy. It reflects the social position of those positioned to benefit from the view that the market is a just, effective, or even acceptable system for rewarding talent and virtue and punishing their opposites and that, therefore, removal of “artificial” impediments to its functioning like race and gender will make it even more efficient and just.
From this perspective even the “left” antiracist line that we must fight both economic inequality and racial inequality, which seems always in practice to give priority to “fighting racism” (often theorized as a necessary precondition for doing anything else), looks suspiciously like only another version of the evasive “we’ll come back for you” (after we do all the business-friendly stuff) politics that the Democrats have so successfully employed to avoid addressing economic injustice.

Dele Alli says he blamed himself for Mauricio Pochettino getting sacked at Tottenham
Tottenham midfielder Dele Alli says he was very upset when he heard the surprising news that Mauricio Pochettino had been sacked, and couldn't wait to see him for a chat
by Jake Polden, https://www.mirror.co.uk/authors/jake-polden/Dele Alli says he blamed himself when Mauricio Pochettino was sacked as Tottenham boss.
Pochettino was relieved of his duties at Spurs last Tuesday, after five years at the club, and replaced by Jose Mourinho.
The Tottenham players went to see Pochettino at his house after the news was announced, and Alli said he and the Argentine sat down and spoke as friends.
"I think it's so clear what Mauricio meant to the players," said Alli.
"He helped me grow a lot. I came here as an 18-year-old and had my ups and downs here. When I found out I was upset and I wanted to speak to him. I went to see him.
"I've seen him more than my family over the past five years. After I heard the news I couldn't wait to see him. I was very upset.
"It wasn't so much a conversation about football more two friends having a chat."
Pochettino was sacked following a poor run of results, with Tottenham floundering outside of the top four places having picked up just 14 points in 12.
Alli featured just five times under Pochettino in the league this season, but says he initially felt partly responsible for the Argentine getting the sack.
Alli added: "I would be lying if I didn't blame myself when it first happened rather than looking at the bigger picture. We had a great journey. You can't help but feel like you're to blame because you're out there but I realised I gave 110 per cent always.
"We've worked with Mauricio for so long. It's new to a lot of us. The squad we had was a lot of young players coming in and it's the first time we've had a change in manager.
"We know where we should be and the talent we have. It's important that we show everyone. This season doesn't show how good we are as a squad and that's why we're not worried.
"You want to impress but at the same time you just want to win games. We've always given everything to win."

How much you make on this quiz depends on your own performance, and on your group’s performance.
Your payoff is calculated as follows:
Each correct answer is worth {{ Constants.stakes }}. Everybody on your team will keep half of what they earn for themselves. The other half will be put into a pot and will be evenly divided between all team members.
In mathematical terms:
Your payoff = (0.5 * the number of questions you answer correctly) + (0.5 * the total number of questions your team answers correctly / the number of people on your team).
Note, though, that we have a {{ Constants.minimum_payoff }} minimum payment policy at ESSEXLab: If your payoff as determined by this quiy is less than {{ Constants.minimum_payoff }} you will be paid {{ Constants.minimum_payoff }}.
That means that you can make between {{ Constants.minimum_payoff }} and {{ Constants.maximum_payoff }} (if everybody on your team answers all questions correctly).


method of static class JsNgram
Description
Show found result. Both for perfect matches and partial matches.
Example
JsNgram.showFound(true, selector, 'a/b.txt', 1, 100);
Usage
showFound(isPerfection, selector, doc, start, limit);
Argument isPerfection is a boolean value whether it is for perfect matches or partial matches. Argument selector is a html element to place the result. Argument doc should be null for document listing level, and should be a document id for hit listing level. Argument start is a number of items to skip. Argument limit is a number of items to show at once.
This method is just a branching point of two methods showFoundByHit and showFoundByDoc. They are to show hits inside a document and to show documents, respectively.
Returns a hash object with a key deferred
with value as an array of jQuery deferred object.
It also has a key next
when there are records not shown yet.


Before describing the Java API usage, it is first useful to examine the exceptions thrown by those APIs. So, briefly, this section describes the exceptions that you can expect to encounter when writing JE applications.
All of the JE APIs throw DatabaseException
.
DatabaseException
extends java.lang.Exception
. Also, the following
classes are subclasses of DatabaseException
:
DatabaseNotFoundException
Thrown whenever an operation requires a database, and that database cannot be found.
LockConflictException
The common base class for all exceptions that result from record lock conflicts. Upon receiving this exception, any open cursors must be closed, the enclosing transaction aborted and, optionally, the transaction retried. Transactions are described in the Berkeley DB, Java Edition Getting Started with Transaction Processing guide.
RunRecoveryException
Thrown whenever JE experiences a catastrophic error such that recovery needs to be run on the database. If you receive this exception, you must reopen your environment so as to allow normal recovery to run. See Databases and Log Files for more information on how normal recovery works.
Note that when reopening your environment, you should stop all database read and write activities, close all your cursors, close all your databases, and then close and reopen your environment.
Note that DatabaseException
and its subclasses belong to the
com.sleepycat.je
package.


Individual Project¶
For this individual project, you are welcome to consult with Prof. Mayes and your classmates, but the work must be your own.
The project should have the following attributes:
- It should help you with a task that you regularly perform or expect to perform in the future. For example, are there calculations or plots that you have done more than once using Excel, which could be replaced by a reliable Python program?
- You should start the project from a cookiecutter template.
- The program should be able to run from the command line.
- File names, variable names, and formatting should follow conventions discussed in class (see https://www.python.org/dev/peps/pep-0008/).
- Tests must be included in the project. These tests should cover at least 90% of the code in the main Python scripts, and should pass when I run them on my computer (a Mac OSX running Python 3.6.1).
Resources to help you¶
In addition to the example project https://github.com/team-mayes/arthritis_proj_demo that you will expand up on in HW6, the repo https://github.com/team-mayes/che696_examples has some additional Python scripts to provide more examples for you to work from.
Examples of projects that would receive full credit¶
The length of the project will depend upon the task it is intended to perform. At a minimum, there should be two options that the user can choose to control the output of the program. Two examples of projects that would receive full points are:
- Under arthritis_proj_demo,
data_proc.py
and its tests. - Under che696_examples,
tex_add_spell
and its tests. - Under che696_examples,
add_to_each_line
with the function called fromcommon
, and its tests.
The other scripts in che696_examples are longer and more complex than necessary; they are included in the examples because they functionality that may be of interest.
Due date and submission instructions¶
By November 21, use Canvas to submit a link to your github project. You are welcome to turn it in early; if I see that any criterion is not passed, I will let you know so you have time to fix this before the final due date.

In its simplest form, an activity consists of an actor, a verb, an an object, and a target. It tells the story of a person performing an action on or with an object -- "Geraldine posted a photo to her album" or "John shared a video". In most cases these components will be explicit, but they may also be implied.
It is a goal of this specification to provide sufficient metadata about an activity such that a consumer of the data can present it to a user in a rich human-friendly format. This may include constructing readable sentences about the activity that occurred, visual representations of the activity, or combining similar activities for display.
The basic properties that comprise the description of an activity are defined in the following sections.
Within this specification, an object is a thing, real or imaginary, which participates in an activity. It may be the entity performing the activity, or the entity on which the activity was performed. An object consists of properties defined in the following sections. Certain object types may further refine the meaning of these properties, or they may define additional properties.
Some types of objects may have an alternative visual representation in the form of an image, video or embedded HTML fragments. A Media Link represents a hyperlink to such resources.
An Activity Stream is a collection one or more individual activities. The relationship between the activities within the collection is undefined by this specification.
| TOC |
The text of this specification provides the sole definition of conformance. Examples in this specification are non-normative.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119] (Bradner, S., “Key words for use in RFCs to Indicate Requirement Levels,” March 1997.).
This specification allows the use of IRIs [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.). Every URI [RFC3986] (Berners-Lee, T., Fielding, R., and L. Masinter, “Uniform Resource Identifier (URI),” January 2005.) is also an IRI, so a URI may be used wherever below an IRI is named. There are two special considerations: (1) when an IRI that is not also a URI is given for dereferencing, it MUST be mapped to a URI using the steps in Section 3.1 of [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.) and (2) when an IRI is serving as an id value, it MUST NOT be so mapped.
| TOC |
Activities are serialized using the JSON format, as defined in [RFC4627] (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.). Alternative serializations MAY be used but are outside the scope of this specification.
In the JSON serialization, absent properties MAY be represented either by an explicit declaration of the property whose value is null or by omitting the property declaration altogether at the option of the publisher; these two representations are semantically equivalent. If a property is having a value whose type is a JSON array, the absence of any items in that array MUST be represented by omitting the property entirely or publishing it with the value null, and MUST NOT be represented as an empty array, except as otherwise stated in the definition of a specific property.
Unless otherwise specified, all properties specifying date and time values within the JSON serialization, including extensions, MUST conform to the "date-time" production in [RFC3339] (Klyne, G., “Date and Time on the Internet: Timestamps,” July 2002.). In addition, an uppercase "T" character MUST be used to separate date and time, and an uppercase "Z" character MUST be present in the absence of a numeric time zone offset.
| TOC |
Following is a simple, minimal example of a JSON serialized activity:
{ "published": "2011-02-10T15:04:55Z", "actor": { "url": "http://example.org/martin", "objectType" : "person", "id": "tag:example.org,2011:martin", "image": { "url": "http://example.org/martin/image", "width": 250, "height": 250 }, "displayName": "Martin Smith" }, "verb": "post", "object" : { "url": "http://example.org/blog/2011/02/entry", "id": "tag:example.org,2011:abc123/xyz" }, "target" : { "url": "http://example.org/blog/", "objectType": "blog", "id": "tag:example.org,2011:abc123", "displayName": "Martin's Blog" } }
A more extensive, single-entry Activity Stream follows. In addition to containing a number of required and optional core properties, the example contains the additional, undefined extension properties "foo" and "foo2" for illustrative purposes only.
{ "items" : [ { "published": "2011-02-10T15:04:55Z", "foo": "some extension property", "generator": { "url": "http://example.org/activities-app" }, "provider": { "url": "http://example.org/activity-stream" }, "title": "Martin posted a new video to his album.", "actor": { "url": "http://example.org/martin", "objectType": "person", "id": "tag:example.org,2011:martin", "foo2": "some other extension property", "image": { "url": "http://example.org/martin/image", "width": 250, "height": 250 }, "displayName": "Martin Smith" }, "verb": "post", "object" : { "url": "http://example.org/album/my_fluffy_cat.jpg", "objectType": "photo", "id": "tag:example.org,2011:my_fluffy_cat", "image": { "url": "http://example.org/album/my_fluffy_cat_thumb.jpg", "width": 250, "height": 250 } }, "target": { "url": "http://example.org/album/", "objectType": "photo-album", "id": "tag:example.org,2011:abc123", "displayName": "Martin's Photo Album", "image": { "url": "http://example.org/album/thumbnail.jpg", "width": 250, "height": 250 } } } ] }
| TOC |
| Property | Value | Description |
|---|---|---|
| actor | Object (Object Serialization) | Describes the entity that performed the activity. An activity MUST contain one actor property whose value is a single Object (Object Serialization). |
| content | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | Natural-language description of the activity encoded as a single JSON String containing HTML markup. Visual elements such as thumbnail images MAY be included. An activity MAY contain a content property. |
| generator | Object (Object Serialization) | Describes the application that generated the activity. An activity MAY contain a generator property whose value is a single Object (Object Serialization). |
| icon | Media Link (Media Link Serialization) | Description of a resource providing a visual representation of the object, intended for human consumption. The image SHOULD have an aspect ratio of one (horizontal) to one (vertical) and SHOULD be suitable for presentation at a small size. An activity MAY have an icon property. |
| id | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | Provides a permanent, universally unique identifier for the activity in the form of an absolute IRI [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.). An activity SHOULD contain a single id property. If an activity does not contain an id property, consumers MAY use the value of the url property as a less-reliable, non-unique identifier. |
| object | Object (Object Serialization) | Describes the primary object of the activity. For instance, in the activity, "John saved a movie to his wishlist", the object of the activity is "movie". An activity SHOULD contain an object property whose value is a single Object (Object Serialization). If the object property is not contained, the primary object of the activity MAY be implied by context. |
| published | [RFC3339] (Klyne, G., “Date and Time on the Internet: Timestamps,” July 2002.) date-time | The date and time at which the activity was published. An activity MUST contain a published property. |
| provider | Object (Object Serialization) | Describes the application that published the activity. Note that this is not necessarily the same entity that generated the activity. An activity MAY contain a provider property whose value is a single Object (Object Serialization). |
| target | Object (Object Serialization) | Describes the target of the activity. The precise meaning of the activity's target is dependent on the activities verb, but will often be the object the English preposition "to". For instance, in the activity, "John saved a movie to his wishlist", the target of the activity is "wishlist". The activity target MUST NOT be used to identity an indirect object that is not a target of the activity. An activity MAY contain a target property whose value is a single Object (Object Serialization). |
| title | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | Natural-language title or headline for the activity encoded as a single JSON String containing HTML markup. An activity MAY contain a title property. |
| updated | [RFC3339] (Klyne, G., “Date and Time on the Internet: Timestamps,” July 2002.) date-time | The date and time at which a previously published activity has been modified. An Activity MAY contain an updated property. |
| url | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | An IRI [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.) identifying a resource providing an HTML representation of the activity. An activity MAY contain a url property. |
| verb | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | Identifies the action that the activity describes. An activity SHOULD contain a verb property whose value is a JSON String that is non-empty and matches either the "isegment-nz-nc" or the "IRI" production in [RFC3339] (Klyne, G., “Date and Time on the Internet: Timestamps,” July 2002.). Note that the use of a relative reference other than a simple name is not allowed. If the verb is not specified, or if the value is null, the verb is assumed to be "post" (The "post" Verb). |
| TOC |
| Property | Value | Description |
|---|---|---|
| duration | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] int | A hint to the consumer about the length, in seconds, of the media resource identified by the url property. A media link MAY contain a "duration" property when the target resource is a time-based media item such as an audio or video. |
| height | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] int | A hint to the consumer about the height, in pixels, of the media resource identified by the url property. A media link MAY contain a height property when the target resource is a visual media item such as an image, video or embeddable HTML page. |
| url | String | The IRI of the media resource being linked. A media link MUST have a url property. |
| width | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] int | A hint to the consumer about the width, in pixels, of the media resource identified by the url property. A media link MAY contain a width property when the target resource is a visual media item such as an image, video or embeddable HTML page. |
| TOC |
| Property | Value | Description |
|---|---|---|
| attachments | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] Array of Objects (Object Serialization) | A collection of one or more additional, associated objects, similar to the concept of attached files in an email message. An object MAY have an attachments property whose value is a JSON Array of Objects (Object Serialization). |
| author | Object (Object Serialization) | Describes the entity that created or authored the object. An object MAY contain a single author property whose value is an Object (Object Serialization) of any type. Note that the author field identifies the entity that created the object and does not necessarily identify the entity that published the object. For instance, it may be the case that an object created by one person is posted and published to a system by an entirely different entity. |
| content | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | Natural-language description of the object encoded as a single JSON String containing HTML markup. Visual elements such as thumbnail images MAY be included. An object MAY contain a content property. |
| displayName | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | A natural-language, human-readable and plain-text name for the object. HTML markup MUST NOT be included. An object MAY contain a displayName property. If the object does not specify an objectType property, the object SHOULD specify a displayName. |
| downstreamDuplicates | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] Array of Strings | A JSON Array of one or more absolute IRI's [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.) identifying objects that duplicate this object's content. An object SHOULD contain a downstreamDuplicates property when there are known objects, possibly in a different system, that duplicate the content in this object. This MAY be used as a hint for consumers to use when resolving duplicates between objects received from different sources. |
| id | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | Provides a permanent, universally unique identifier for the object in the form of an absolute IRI [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.). An object SHOULD contain a single id property. If an object does not contain an id property, consumers MAY use the value of the url property as a less-reliable, non-unique identifier. |
| image | Media Link (Media Link Serialization) | Description of a resource providing a visual representation of the object, intended for human consumption. An object MAY contain an image property whose value is a Media Link (Media Link Serialization). |
| objectType | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | Identifies the type of object. An object MAY contain an objectType property whose value is a JSON String that is non-empty and matches either the "isegment-nz-nc" or the "IRI" production in [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.). Note that the use of a relative reference other than a simple name is not allowed. If no objectType property is contained, the object has no specific type. |
| published | [RFC3339] (Klyne, G., “Date and Time on the Internet: Timestamps,” July 2002.) date-time | The date and time at which the object was published. An object MAY contain a published property. |
| summary | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | Natural-language summarization of the object encoded as a single JSON String containing HTML markup. Visual elements such as thumbnail images MAY be included. An activity MAY contain a summary property. |
| updated | [RFC3339] (Klyne, G., “Date and Time on the Internet: Timestamps,” July 2002.) date-time | The date and time at which a previously published object has been modified. An Object MAY contain an updated property. |
| upstreamDuplicates | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] Array of Strings | A JSON Array of one or more absolute IRI's [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.) identifying objects that duplicate this object's content. An object SHOULD contain an upstreamDuplicates property when a publisher is knowingly duplicating with a new ID the content from another object. This MAY be used as a hint for consumers to use when resolving duplicates between objects received from different sources. |
| url | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | An IRI [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.) identifying a resource providing an HTML representation of the object. An object MAY contain a url property |
| TOC |
A "collection" is a generic list of Objects (Object Serialization) of any object type. The objectType of each item in the collection MAY be omitted if the type of object can be established through context. The collection is used primarily as the root of an Activity Streams document as described in Section 4 (The Activity Stream JSON Document), but can be used as the value of extension properties in a variety of situations.
| Property | Value | Description |
|---|---|---|
| totalItems | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] Integer | Non-negative integer specifying the total number of activities within the stream. The Stream serialization MAY contain a count property. |
| items | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] Array of Objects (Object Serialization) | An array containing a listing of Objects (Object Serialization) of any object type. If used in combination with the url property, the items array can be used to provide a subset of the objects that may be found in the resource identified by the url. |
| url | JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] String | An IRI [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.) referencing a JSON document containing the full listing of objects in the collection. |
A valid Collection object serialization MUST contain at least the url or items properties.
| TOC |
The above defined JSON serialization can be used to represent activities, objects and media links in any JSON context. This section defines one particular use of the above formats to publish a JSON document representing a stream of activities.
Publishers using this format MUST produce a valid JSON document whose root value is a Collection (Collection Serialization). This object MUST, at a minimum, include the items property whose objects MUST be Activities (Activity Serialization).
| TOC |
The values of multiple Object's (Object Serialization) id, upstreamDuplicates, and downstreamDuplicates properties can be compared to determine if the objects represent duplicate content. Processors MUST compare these values on a character-by-character basis (in a case-sensitive fashion). Comparison operations MUST be based solely on the IRI character strings and MUST NOT rely on dereferencing the IRIs or URIs mapped from them.
As a result, two IRIs that resolve to the same resource but are not character-for-character identical will be considered different for the purposes of identifier comparison.
| TOC |
This specification defines one initial verb and defers to other specifications to define additional verb and object types as defined in Section 8 (Extension Object Types and Verbs).
The "post" verb describes the act of authoring an object and then publishing it online. The actor can be any entity; the object can be of any object type; and the target, if specified, can be of any object type. A target, however, is not required.
| TOC |
Because the "post" verb is defined to include the act of publishing an object online, it is possible to assume an implied "post" activity for any object even if such an activity was never explicitly published or received. The properties of this implied activity are as follows; any property not explicitly listed here is absent from the resulting activity unless the consumer is able to infer a value based on out-of-band information outside the scope of this specification:
- actor
- The actor of the implied activity is unknown unless the consumer is able to infer an actor based on information outside the scope of this specification. For example, the consumer may know via some out-of-band information that all of the objects in a particular document were posted by a particular user.
- object
- The object of the implied activity is the object for which this implied activity is being constructed.
- verb
- The verb of the implied activity is "post".
- published
- The published of the implied activity is unknown unless the consumer is able to infer a time based on information outside the scope of this specification.
| TOC |
The "activity" object type indicates that an Object represents an Activity. It can be used whenever an event involving another activity is described within an Activity Stream. For instance, when one user "shares" or "reposts" an activity from another user.
In addition to the core Object properties, an "activity" object MAY contain any combination of the properties defined for an Activity (Activity Serialization). The values of the object's id and url fields MUST match those of the activity being described.
Note that an activity object MUST be processable as both an Object (Object Serialization) and an Activity (Activity Serialization) and may contain fields from either construct, some of which may overlap or duplicate content. When duplication of content may occur, an implementation SHOULD choose to use the fields from the Activity (Activity Serialization) object. For instance, in an activity object, the Activity's title property and the Object's displayName properties serve identical functions, therefore the use of the title property SHOULD be favored over the use of displayName.
The example below illustrates an activity in which one user, Jane, is sharing another activity performed by a second user, John.
{ "published": "2011-02-10T15:04:55Z", "actor": { "objectType" : "person", "id": "tag:example.org,2011:jane" }, "verb": "share", "object" : { "objectType":"activity", "title": "John posted a photo", "id": "tag:example.org,2011:abc123", "verb": "post", "actor": { "objectType":"person", "id":"tag:example.org,2011:john" }, "object": { "objectType":"photo", "url":"http://example.org/album/my_fluffy_cat.jpg" } } }
| TOC |
Other specifications MAY define new object types and verbs for use with the concepts and serializations defined in this specification. To be clear, new extension properties can be added anywhere in the JSON serialization of an object or activity.
When defining a new verb, the defining specification MUST provide a verb identifier for the new verb and MUST define the meaning of the verb in terms of the actor, object and target properties of the activity, and MUST define whether a target is required and what it represents when present.
When defining a new object type, the defining specification MUST provide an object type identifier for the new object type. The definition of the new object type MAY define additional properties specific to that object type; if so, the specification SHOULD define how these additional properties are to be serialized within the JSON document, and the specification MAY define how these additional properties are to be represented in other serialization formats. The definition of the new object type MAY impose additional meaning or constraint on the core object properties as long as the new definition remains compatible with the definition of the base component.
Additional extension properties MAY also be defined for Activities (Activity Serialization) and Media Links (Media Link Serialization). The specification of these properties SHOULD define how they are to be serialized within the JSON document, and the specification MAY define how they are to be represented in other serialization formats.
New properties SHOULD be defined such that the Object (Object Serialization), Activity (Activity Serialization) or Media Link (Media Link Serialization) would remain useful if those properties are omitted or removed during processing, to enable graceful fallback by consumers that do not implement the extension properties or alternative representations that are unable to represent the extensions.
Processors that encounter unfamiliar extension properties within an Object (Object Serialization), Activity (Activity Serialization) or Media Link (Media Link Serialization) MUST NOT stop processing or signal an error and MUST continue processing the items as if the extension properties were not present.
| TOC |
This specification defines the primary representation for "activities", "objects" and "media links" in terms of the JSON serialization format. Other specifications MAY define additional serializations of these items. If the new serialization is compatible with the JSON data model, the new representation SHOULD be defined as a transformation of the raw JSON structures.
Defining a new representation as a transformation from JSON will allow the new representation to automatically support additional properties added for new object types as described in Section 8 (Extension Object Types and Verbs). Otherwise the representation of these new properties must be defined on a case-by-case basis.
| TOC |
A Re-publisher is an agent which receives "activities" or "objects" and then transmits these items to other agents.
When a Re-publisher transmits an "activity", the Re-publisher MUST preserve the original verb, published, actor, object and target properties. The Re-publisher MAY preserve the remaining properties, OR the Re-publisher MAY omit these properties entirely or replace these properties with locally-determined values.
When a Re-publisher transmits an object, the Re-publisher MUST maintain the full integrity of the object, including any extension properties, and retain the original id value OR, if maintaining full fidelity is not possible the Re-publisher MUST assign this copy a new id and include the id of the original object as a value of the upstreamDuplicates property of the new copy. In the latter case, a new object is created which is considered to be a duplicate of the original.
| TOC |
Publishers or Consumers implementing Activity Streams as a stream of public data may also want to consider the potential for unsolicited commercial or malicious content and should take preventative measures to recognize such content and either identify it or not include it in their stream implementations.
Publishers should take reasonable measures to make sure potentially malicious user input such as cross-site scripting attacks are not included in the Activity Streams data they publish.
Consumers that re-emit ingested content to end-users MUST take reasonable measures if emitting ingested content to make sure potentially malicious ingested input is not re-emitted.
Consumers that re-emit ingested content for crawling by search engines should take reasonable measures to limit any use of their site as a Search Engine Optimization loophole. This may include converting un-trusted hyperlinks to text or including a rel="nofollow" attribute.
Consumers should be aware of the potential for spoofing attacks where the attacker publishes activities or objects with falsified property values with the intent of injecting malicious content, hiding or corrupting legitimate content, or misleading users.
Activity Streams are JSON Documents and are subject to the same security considerations described in [RFC4627] (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.).
Activity Streams implementations handle URIs. See Section 7 of [RFC3986] (Berners-Lee, T., Fielding, R., and L. Masinter, “Uniform Resource Identifier (URI),” January 2005.).
Activity Streams implementations handle IRIs. See Section 8 of [RFC3987] (Duerst, M. and M. Suignard, “Internationalized Resource Identifiers (IRIs),” January 2005.).

vignettes/forecast-example.Rmd
forecast-example.Rmd
Forecasting is a frequent activity for the learning analytics practitioner. In this example we will explore how to extract and format data with the moodleR package for a forecasting exercise.
In addition to moodleR
we will be using dplyr
and ggplot2
in this example. Let’s go ahead and load these packages.
For this example we will use the Moodle log, which we can access using the mdl_log()
function.
my_log <- mdl_log()
Once we have this reference we can summarize log-lines and unique users per day by using dplyr verbs. Since we intend to convert the timecreated
column using the anytime
package, we will need to call dplyr::collect()
and convert our reference to a tibble.
We can now visualize the data.
my_timeseries %>%
ggplot(aes(date,N))+
geom_line() +
scale_y_continuous(labels=scales::label_number_si())
my_timeseries %>%
ggplot(aes(date,Users))+
geom_line() +
scale_y_continuous(labels=scales::label_number_si())
Two clear patterns emerge, There is a break at the end of March, beginning of April and the semester is over at the beginning of June. Neither of these observations are in any way unexpected, and would probably be arrived at using common sense, with some minimal input from the institution in question.
For the purposes of this example we will divide the dataset into two parts, with a cutoff in early June.
my_cutoff <- as.Date("2020-06-01")
my_timeseries_1 <- my_timeseries %>%
filter(date <=my_cutoff )
my_timeseries_2 <- my_timeseries %>%
filter(date > my_cutoff )
my_timeseries_1 %>%
ggplot(aes(date,Users))+
geom_line() +
scale_y_continuous(labels=scales::label_number_si())
my_timeseries_2 %>%
ggplot(aes(date,Users))+
geom_line() +
scale_y_continuous(labels=scales::label_number_si())
A seasonal pattern is obvious, and clearly the activity mostly follows a weekly pattern.
We can use either of the subsets of data to create an arima model, available in the stats
package. We set the order and period parameters to estimate a fit.
my_model_2
#>
#> Call:
#> arima(x = my_timeseries_2$Users, seasonal = list(order = c(3L, 0L, 0L), period = 7L))
#>
#> Coefficients:
#> sar1 sar2 sar3 intercept
#> 0.6761 0.3622 -0.1834 972.0461
#> s.e. 0.1593 0.1880 0.1672 99.3799
#>
#> sigma^2 estimated as 29454: log likelihood = -418.57, aic = 847.14
We can now use the model to predict the number of unique users for the next month:
my_pred <- predict(my_model_2,30)$pred
We can use ggplot to visualize the prediction made by our model.
start_date <- max(my_timeseries_2$date)-1
data.frame(date = start_date + 1:length(my_pred), Users = my_pred) -> predicted_users_2
predicted_users_2 %>%
ggplot(aes(x = date, y = Users))+
geom_line() +
scale_y_continuous(labels=scales::label_number_si())
And we can combine the two in one plot. For this we will need to create a data.frame
since this is what ggplot expects as input.
my_timeseries_2 %>%
select(date,Users) %>%
mutate(Type = "Observed") %>%
rbind(
predicted_users_2 %>%
mutate(Type = "Predicted")
) -> combined_ts
my_plot <- combined_ts %>%
ggplot(aes(date,Users, color = Type))+
geom_line() +
scale_y_continuous(labels=scales::label_number_si())
my_plot
And we can see that the prediction is consistent with the observed pattern and generally declining trend.
This trend can also be visualized by adding a geom_smooth to the plot.
my_plot +
geom_smooth(
se=FALSE,
mapping = aes(x=date,y=Users),
data = combined_ts %>% select(date,Users),
inherit.aes = FALSE,
lty=2,
color = "gray")

Andy Ruiz: Mexican champion vows to 'break down' Anthony Joshua's ego
- Andy Ruiz vs Anthony Joshua fight will hold on December 7 in Saudi Arabia
- The Mexican champion believes he will break down Joshua's ego and mentality again
- Ruiz hopes to retain his world heavyweight titles with another win over the Briton
Andy Ruiz, heavyweight boxing champion, has vowed to break down Anthony Joshua's ego and mentality when they both meet for the rematch of their fight in Saudi Arabia.
The Mexican will prove that his victory over Joshua at Madison Park New York in June was not a fluke when they meet again.
The rematch, tagged fight of dunes, is scheduled to hold in December 7 and the 30-year-old boxer has expressed confidence while vowing to beat the British-Nigerian heavyweight star.
Speaking with Sky Sport ahead of the bout, the Mexican champion boasted about his ability and threatened to beat Joshua "even faster."
"If he wants to bang, it's better for me. I love to bang because that's the fighter that I am," Ruiz Jr exclusively told Sky Sports.
Andy Ruiz Jr, raises suspicions about Anthony Joshua ahead of epic rematch
"December 7 we have to pressure, work the body, break him down. Especially his mentality.
"We've got to see where he's at because all the pressure is on him. The pressure isn't on me because I followed my dream, made my dreams come true."
Ruiz Jr, in a bout he was less considered favourite, stunned the world when he defeated Joshua through a seventh round knockout to cart away the Briton's WBA, IBF & WBO belts in June 1, 2019, in New York.
The boxing champion had earlier revealed he would be "10lbs lighter" as he seeks to be a better fighter in the rematch.

>From Mr. Tower Outer Circle Regents Park NW3 4RY London Good Day Please accept my sincere apologizes if my email does not meet your business or personal ethics. I will first introduce myself as Mr. Amos Tower, a staff in the Private Clients Section of a well-known bank, here in London, England. One of our accounts, with holding balance of £15,000,000 (Fifteen Million Pounds Sterling) has been dormant and last operated three years ago. From my investigations and confirmation, the owner of the said account, a foreigner by name John Shumejda died on the 4th of January 2002 in a plane crash in Birmingham; you can view this CNN website http://edition.cnn. com/2002/WORLD/europe/01/04/england.plane/ for details on the crash. Since then, nobody has done anything as regards the claiming of this money, as he has no family member that has any knowledge as to the existence of either the account or the funds; and also Information from the National Immigration also states that he was single on entry into the UK. I have confidently discussed this issue with some of the bank officials and we have agreed to find a reliable foreign partner to deal with. We therefore propose to do business with you, standing in as the next of kin of these funds from the deceased and funds released to you after necessary processes have been followed. This transaction is totally free of risk and troubles as the fund is legitimate and does not originate from drug, money laundry, terrorism or any other illegal act. On your interest, let me hear from you. Warm Regards, Mr. Amos Tower.
