My favorite Einstein quote is the one that says, it is the theory that determines the data.  ;-)

So writes someone to a mailing list I’m on. I couldn’t find a source for that, but it might derive from this Einstein quotation:

Whether you can observe a thing or not depends on the theory which you use. It is the theory which decides what can be observed.

 Unification of Fundamental Forces (1990) by Abdus Salam ISBN 0521371406, page 99, related by Heisenberg.

(By the way, my quick Internet “research” turned up no reliable sources for a related quotation often attributed to Marshall McLuhan: “I wouldn’t have seen it if I hadn’t believed it.” It sounds like him, though.)

But no matter. What I really want to talk about is how the Einstein quotation applies to marketing:

Messages create markets.

This is I think quite literally the case in the pre-personalization view of markets as corresponding to demographic slices. The particular demographics that are assumed to constitute a market are the ones that are believed to be susceptible to the same broadcast message. If white adolescents are thought to respond to “Be a Pepper”, then they are a market. If suburban dads are susceptible to “Come alive with Subaru!”, then they are a market. If short baseball fans are not susceptible to the same message, they are not a market.

Such markets have no reality other than their susceptibility to a message. If and when (= now) messages can be delivered to, and even designed for, based on particular traits, preferences, and behaviors of individuals,  “markets” ?cease to exist. Since personalization can more effectively play on human susceptibility to non-rational appeals, many of us, including me, are of course disturbed about this development. 

But there is another side of this as well.  As Doc Searls once said, markets are conversations. If customers and users now talk with one another about the things they want to buy and have bought, then markets once again have some actual reality. The fact that these conversations occur in and on networks makes these markets fluid but does not make them less real.

On Feb. 19, 2020, Elliot Noss testified before the Canadian Radio and Television Commission about how to knock Canada off the very top of the list of the world’s most expensive mobile connections. It’s very much worth a read [pdf] or view.

Elliot is the president and CEO of Tucows, and the found of Hover and Ting. These companies are profitable, but they are also driven by Elliot’s commitment to supporting an open Internet … where openness includes open affordable. Ting, for example, provides excellent wireless service at prices that should make the Big Boys blush in shame — although they’d first have to look up “shame” in the dictionary — while also providing what may be the best customer service in the world. Not exaggerating. Hover is also a very excellent Web registrar.

Yes, Elliot is a friend of mine. But one of the reasons I’m so attached to him is that he is so thoroughly decent. He is what my tribe calls a Mensch.

In his testimony, he’s trying to get the Canadian government to support Mobile Virtual Network Operators (MNVOs), as opposed to only supporting “facilities-based providers” that, by definition, “serve a subscriber using its own network facilities and spectrum…” [pdf] The facilities-based providers own the wire or cable going to your house, and they compete on the basis of their coverage. An MNVO (such as Ting) rents access to the physical infrastructure and provides services to customers, competing on factors like price, service, and quality … which is what we customers want. (Yes, Canada supporting MNVOs would open up business opportunities for Elliot personally, but that is not his primary driver.)

Here’s a taste of Elliot’s remarks:

Telecommunication services are infrastructure, just like water, electricity and roads. Think of telephone service provided over copper networks. From their onset they were regulated infrastructure with rate of return economics. When we introduced mobile phone service provided
over the public resource of spectrum it was for making phone calls and was considered a luxury. Today it is primarily for using small computers, that we still anachronistically call “phones”, to consume data. And it is for everyone. Lower income Canadians need access to mobile data just
like other Canadians. Not for “occasional use”. Not at lower data rates. In fact lower income Canadians are the most likely Canadians to NOT have a fixed Internet connection at home.

Telecom is infrastructure. Which leads me to my most heretical point. If telecom is infrastructure, and it is, then the desire for facilities-based competition is misplaced. We do not require facilities-based competition with any other infrastructure. In fact it would seem absurd if we were
talking about it in connection with water or electricity.

I am an Elliot Noss fanboy, and proud of it.

Brink has just posted a piece of mine that suggests that the Internet and machine learning have been teaching companies that our assumptions about the predictability of the future — based in turn on assumptions about the law-like and knowable nature of change — don’t hold. But those are the assumptions that have led to the relatively recent belief in the efficacy of strategy.

My article outlines some of the ways organizations are facing the future differently. And, arguably, more realistically.

Digital Extremes wants to break the trend of live-service games meticulously planning years of content ahead of time using road maps…’What happens then is you don’t have a surprise and you don’t have a world that feels alive,’ [community director Rebecca] Ford says. ‘You have a product that feels like a result of an investor’s meeting 12 months ago.'”

— Steven Messner, “This Means War,” PC Gamer, Feb. 2020, p. 34

Video games have been leading indicators for almost forty years. It was back in the early 1980s that games started welcoming modders who altered the visuals, turning Castle Wolfenstein into Castle Smurfenstein, adding maps, levels, cars, weapons, and rules to game after game. Thus the games became more replayable. Thus the games became whatever users wanted to make them. Thus games — the most rule-bound of activities outside of a law court or a tea ceremony — became purposefully unpredictable.

Rebecca Ford is talking about Warframe, but what she says about planning and road maps points the way for what’s happening with business strategies overall. The Internet has not only gotten us used to an environment that is overwhelming and unpredictable, but we’ve developed approaches that let us leverage that unpredictability, from open platforms to minimum viable products to agile development.

The advantage of strategy is that it enables an organization to focus its attention and resources on a single goal. The disadvantages are that strategic planning assumes that the playing field is relatively stable, and that change general happens according to rules that we can know and apply. But that stability is a dream. Now that we have tech that lets us leverage unpredictability, we are coming to once again recognize that strategies work almost literally by squinting our eyes so tight that they’re almost closed.

Maybe games will help us open our eyes so that we do less strategizing and more playing.

Everyday Chaos, including four rules to guide your expectations about machine learning.

It’s great to see a pre-publication post so on track about what the book says and how it applies to business.

At the PAPis conference Bas Nieland, CEO and Co-Founder of Datatrics, is talking about how to predict the color of shoes your customer is going to buy. The company tries to “make data science marketeer-proof for marketing teams of all sizes.” IT ties to create 360-degree customer profiles by bringing together info from all the data silos.

NOTE: Live-blogging. Getting things wrong. Missing points. Omitting key information. Introducing artificial choppiness. Over-emphasizing small matters. Paraphrasing badly. Not running a spellpchecker. Mangling other people’s ideas and words. You are warned, people.

They use some machine learning to create these profiles. The profile includes the buying phase, the best time to present choices to a user, and the type of persuasion that will get them to take the desired action. [Yes, this makes me uncomfortable.]

It is structured around a core API that talks to mongoDB and MySQL. They provide “workbenches” that work with the customer’s data systems. They use BigML to operate on this data.

The outcome are models that can be used to make recommendations. They use visualizations so that marketeers can understand it. But the marketeers couldn’t figure out how to use even simplified visualizations. So they created visual decision trees. But still the marketeers couldn’t figure it out. So they turn the data into simple declarative phrases: which audience they should contact, in which channel, what content, and when. E.g.:

“To increase sales, çontact your customers in the buying phase with high engagement through FB with content about jeans on sale on Thursday, around 10 o’clock.”

They predict the increase in sales for each action, and quantify in dollars the size of the opportunity. They also classify responses by customer type and phase.

For a hotel chain, they connected 16,000 variables and 21M data points, that got reduced to 75 variables by BigML which created a predictive model that ended up getting the chain more customer conversions. E.g., if the model says someone is in the orientation phase, the Web site shows photos of recommend hotels. If in the decision phase, the user sees persuasive messages, e.g., “18 people have looked at this room today.” The messages themselves are chosen based on the customer’s profile.

Coming up: Chatbot integration. It’s a “real conversation” [with a bot with a photo of an atttractive white woman who is supposedly doing the chatting]

Take-aways: Start simple. Make ML very easy to understand. Make it actionable.

Q&A

Me: Is there a way built in for a customer to let your model know that it’s gotten her wrong. E.g., stop sending me pregnancy ads because I lost the baby.

Bas: No.

Me: Is that on the roadmap?

Bas: Yes. But not on a schedule. [I’m not proud of myself for this hostile question. I have been turning into an asshole over the past few years.]

Vinny Senguttuvan is Senior Data Scientist at METIS. Before that, he was at Facebook-based gaming company, High 5 Games, which had 10M users. His talk at PAPIs: “Predicting Customers.”

NOTE: Live-blogging. Getting things wrong. Missing points. Omitting key information. Introducing artificial choppiness. Over-emphasizing small matters. Paraphrasing badly. Not running a spellpchecker. Mangling other people’s ideas and words. You are warned, people.

The main challenge: Most of the players play for free. Only 2% ever spend money on the site, buying extra money to play. (It’s not gambling because you never cash out). 2% of those 2% contribute the majority of the revenue.

All proposed changes go through A/B testing. E.g., should we change the “Buy credits” button from blue to red. This is classic hypothesis testing. So you put up both options and see which gets the best results. It’s important to remember that there’s a cost to the change, so the A-B preference needs to be substantial enough. But often the differences are marginal. So you can increase the sample size. This complicates the process. “A long list of changes means not enough time per change.” And you want to be sure that the change affects the paying customers positively, which means taking even longer.

When they don’t have enough samples, they can bring down the confidence level required to make the change. Or they could bias one side of the hypothesis. And you can assume the variables are independent and run simultaneous A-B tests on various variables. High 5 does all three. It’s not perfect but it works.

Second, there is a poularity metric by which they rank or classify their 100 games. They constantly add games — it went from 15 to 100 in two years. This continuously changes the ranking of the games. Plus, some are launched locked. This complicates things. Vinny’s boss came up with a model of an n-dimensional casino, but it was too complex. Instead, they take 2 simple approaches: 1. An average-weighted spin. 2. Bayesian. Both predicted well but had flaws, so they used a type of average of both.

Third: Survival analysis. They wanted to know how many users are still active a given time after they created their account, and when is a user at risk of discontinuing use. First, they grouped users into cohorts (people who joined within a couple of weeks of each other) and plotted survival rates over time. They also observed return rates of users after each additional day of absence. They also implement a Cox survival model. They found that newer users were more likely to decline in their use of the product; early users are more committed. This pattern is widespread. That means they have to continuously acquire new players. They also alert users when they reach the elbow of disuse.

Fourth: Predictive lifetime value. Lifetime value = total revenue from a user over the entire time the the produced. This is significant because of costs: 10-15% of the rev goes into ads to acquire customers. Their 365 day prediction model should be a time series, but they needed results faster, so they flipped it into a regression problem, predicting the 365 day revenue based on the user’s first month data: how they spent, purchase count, days of play, player level achievement, and the date joined. [He talks about regression problems, but I can’t keep up.] At that point it cost $2 to acquire a customer from FB ad, and $6 from mobile apps. But when they tested, the mobile acquisitions were more profitable than those that came from through FB. It turned out that FB was counting as new users any player who hadn’t played in 30 days, and was re-charging them for it. [I hope I got that right.]

Fifth: Recommendation systems. Pandora notes the feature of songs and uses this to recommend similarities. YouTube makes recommendations made based on relations among users. Non-matrix factorization [I’m pretty sure he just made this up] gives you the ability to predict the score for a video that you know nothing about in terms of content. But what if the ratings are not clearly defined? At High 5, there are no explicit ratings. They calculated a rating based on how often a player plays it, how long the session, etc. And what do you do about missing values: use averages. But there are too many zeroes in the system, so they use sparse matrix solvers. Plus, there is a semi-order to the games, so they used some human input. [Useful for library Stackscores

I’m in Talent Garden‘s largest branch, which is also its headquarters, in Milan. It’s a ridiculously large co-working space for startups, with an emphasis on openness. I’m enjoying sitting at a table with a few other people, none of whom I know and all of whom are speaking Italian.

I like co-working spaces enough that if I were looking for a place to work outside of my house, I’d consider joining one. It’s that or the local library. It depends on whether you find being around the young and the digital to be distracting, energizing, or both.

I find it energizing. Nevertheless, the segregation of the young from the old is a cultural and business loss.

Talent Garden ameliorates this by renting space to a handful of established companies (IBM, Cisco, and a bank, here in Milan) to provide mentoring, and so the old companies can get behind startups they find interesting. It’s a good model, although since I’m just here for the afternoon, I don’t know how much actual mingling occurs. Still, it’s a good idea.

I also like that Talent Garden explicitly tries to build community among its users. Not waving-in-the-hall community, but a community of shared space, shared events, and shared ideas. The American co-working space I’m most familiar with has public areas but assumes startups want to work in rooms with closed, solid doors. An open floor plan helps a startup culture to grow, which is perhaps more needed in Italy than in the US. Nevertheless, you can’t have too much community. Well, you can, but that’s easier to remediate than its opposite. (For a US shared space dedicated to building community, check out the treasured Civic Hall in NYC.)

(Note: Unlike the co-working space I’m most familiar with, TG does not provide a free, well-stocked kitchen. Just as well. Free kitchens cause my metabolism to think its faster than it is.)

I’m in Italy to participate in an Aspen Institute event in Venice over the weekend (poor poor me). I stopped in Milan to give a talk, which I internally have titled “Is the Internet Disappointed in Us?” It’s actually a monolog — no slides, no notes — about why my cohort thought the success of the Internet was inevitable, and why I am still optimistic about the Net. If you’re interested in having me in to speak with your group, let me know. Yeah, a plug.

And while I’m plugging, here’s some disclosure: Talent Garden is the venue for this talk, but no one is paying me for it.

Robin Chase is giving a lunchtime talk at the Berkman Center.

NOTE: Live-blogging. Getting things wrong. Missing points. Omitting key information. Introducing artificial choppiness. Over-emphasizing small matters. Paraphrasing badly. Not running a spellpchecker. Mangling other people’s ideas and words. You are warned, people.

There is a totally new organization paradigm that exists next to the Internet, she says. She calls it “Peers, Inc.” It changes how we shape the economy. It’s happening now. Her explanation will be in three parts:

Platforms

First, platforms for participation that leverage excess capacity. E.g., Facebook, Skype, Meetup, YouTube, MOOCs, open source, Blockchain, etc. For example, Skype is a telecoms company built on the excess capacity of its users systems. Working with excess capacity means sharing.

Bed-sharing (couchsurfing, AirBnB) uses excess beds. “It took four years for AirBnB to have more available beds than the largest hotel chain”It took four years for AirBnB to have more available beds than the largest hotel chain (InterContinental): 650,000. Couchsurfing has more than a couple of million.

We invented big institutions to do things that we can’t do as individuals. E.g., large investments, projects that require intelligence in lots of different areas, standardized contracts. And there are things that individuals do better: customization, specialization, creativity, trust.

These two coexist, and the Net enables them to collaborate. She calls this Peers, Inc. (“Institutions and governments are also Inc’s in this world view.”) The Inc’s provide a platform for participation, and the individual provides creativity and specialization.

Robin “adores excess capacity” because it’s green and efficient. Excess capacity is something that’s already been paid for but contains unused value. How do you harness it? 1. You can slice it so only pay for what they use (e.g., ZipCar); this lets you avoid buying more car than you need. 2. You can aggregate (e.g., AirBnB, Waze). 3. Open up these assets, e.g., data.gov and GPS.

The Inc side builds platforms for participation. They organize lots of small parts. “They “Platforms give the power of the large to the small”give the power of the large to the small.” They can scale. She points to a French car-sharing company: BlaBlaCar. Four million people use it every month.

Peers bring diversity. E.g., smartphones and apps. Smartphones are far harder to build than the apps they enable. Over 2M apps have been developed since smartphones were invented in the past seven years. “We’ve seen more innovation than throughout all of human history” because people can build apps that are relevant to their own situations. App creators are free-riders on top of the $600 people spend on their smartphones.

2. Peers Inc give us new powers, which she thinks of as miracles.

“The most depressing thing I know is climate change.” By 2100, we’ll see a 4-6°C increase unless we take dramatic action. What does that feel like? “The last time we were minus 7°F was the last ice age.” Warming the planet that amount transformed the planet. We should expect the same level of change if we boost it another 7°F. By 2060, it will be really awful. So we have to address this.

“Banny Bannerjee says: “You can’t solve exponential problems with linear solutions.””Banny Bannerjee says: “You can’t solve exponential problems with linear solutions.”

The “miracles” give her some optimism:

a. “We can defy the laws of physics” by leveraging excess capacity. If she had proposed building 640,000 rooms in four years she would have been told that that’s not possible. But AirBnb did it by leveraging existing excess capacity.

b. “We can tap exponential learning.” Platforms can get millions of iterations in and can do a lot of learning. E.g., learning a language. A semester is 130 hours. Rosetta Stone teaches the same in 54 hours. But it’s expensive. “My new favorite company is DuoLingo.” They do a lot of A/B testing. They now can teach you a semester in 34 hours. They have 90M people using it. A year and a half ago DuoLingo opened up its processes: Russians learning Balinese, etc. Now 45M of the 90M are learning language pairs DuoLingo did not create. (DuoLingo makes money because they have humans translating sentences from organizations that pay them incrementally.)

c. “The right person will appear.” E.g., Obama raised the prospect of normalizing relationships with Cuba. Six months later, AirBnB had 2,000 listings there, thanks to the Net.

Her only hope for climate change is creating platforms that will address climate “at scale, speed, and locally adapated.” E.g., a platform for a house will remember to turn off the light when there’s been no movement. We’ll get smart cities through the Internet of Things. Distributed energy. Autonomous vehicles, which will arrive in force in the next 5-12 years. We’ll only need 10% of the cars because we’ll be sharing them. “Public transportation will be at the cost of a bus but the speed of cars”Public transportation will be at the cost of a bus but the speed of cars, transforming job opportunities. (But the Internet of Things means that everything is tracked.)

All of these miracles only happen because of both sides of Peers Inc.

3. “Everything that can become a platform will become one.” Old-style industrial capitalism put thick boundaries around companies. Today, what’s inside and outside is blurred.

Four reasons Robin is convinced we’re moving into the collaborative economy:

1. Shared networked assets always provide more value than closed assets

2. More networked minds are smarter than fewer proprietary minds.

3. “The benefits of shared open assets are always larger than the problems associated with open assets.” E.g., yes, some people put scratches in ZipCars, but the company nevertheless is doing very well.

4. What I get is great than what I give.

We are in a time of instability. “Peers Inc is the only structure that can experiment, iterate, evolve and adapt at the pace required.”Peers Inc is the only structure that can experiment, iterate, evolve and adapt at the pace required.

So, how can we structure things so we give up the least privacy necessary? “What is the least privacy loss that delivers a habitable climate”

QA

Q: For me it’s not privacy loss but who we’re losing our privacy to. What about platform accountability? Aren’t we pushing out power into more abstract systems that we cannot see or address?

A: I was on a panel at the Platform Cooperativism conference. I pointed out that these platforms are incredibly expensive. ““He who finances the platforms creates the rules of engagement.”He who finances the platforms creates the rules of engagement.” “I want these platforms created by a distributed, autonomous us.” We don’t have time to just hope this happens. “I have real anxiety.”

Q: [me] Suppose we build protocol instead platforms…

A: I’ve put all of that into the same bucket.

Q: Shareable cars disrupt ZipCar. There will be user agreements. How do we disrupt that?

A: “He who creates the data owns the data.” Autonomous vehicles have a middle space, e.g., around safety and learning issues. It’s in the deep public interest to have this data. But we need to make the privacy issues understandable and parseable by ordinary users so they can choose.

Q: Isn’t privacy gone already?

A: We can still do some structuring.

Q: Why does trust work over the Web, which is mostly anonymous?

A: Ebay was the first to figure out you need ratings and commentaries. We use other people as our proxies for trust.

Q: iRobot’s Roombas currently don’t upload what they’ve learned about the layout of your house. But Nest knows everything. What should the rules be?

A: That’s what I’m asking you. We have to figure this out.

Q: It’d be great if we had more choice about which pieces of info we give to platforms. Is there any work on standard ways of parceling out pieces of our identity?

A: I know people are working on this. “It comes back to the amount of money, time, and marketing it takes to push great ideas into market.”

Q: What are we doing to educate the younger generation about privacy?

A: Maybe you can push Harvard to do appropriate role modeling. Maybe students here could push for an icon system that tells us what data you’re taking from us, etc.

Q: [me] What would you tell a student about the dangers? And would you consider addressing this by putting restrictions on how the data is used, rather than on its collection?

A: How about doing some pilots to see what works? You have to inform people about the dangers as well regulating the industry.

Q: How will we embed public safety concerns into software for self-driving cars?

A: Self-driving cars will always follow the rules. No speeding. No parking in no-parking zones. All the existing rules will be embedded. So we’ll embed the appropriate behavior for ambulances, etc. No siren required. Also: The auto industry always brings up autonomous cars having to decide which person to kill in an accident. But why would you bring up this stupid case? One in a million trips this might happen? There are more deaths than that now. “Right now, 80% of cars are single occupancy. We need to put a high price on that.”Right now, 80% of cars are single occupancy. We need to put a high price on that.

Q: It sounds like you’re describing a train: get somewhere, not park…Why not public transportation?

A: We’ll see how it plays out. It’ll be a complex ecosystem. It’ll be decided city by city. More important than who owns it are: Will they be electric? Will it be 10x more expensive for single occupancy? Will we have pharmacy cars or liquor cars that deliver their wares without having a storefront? Who will design the software?

Q: Practically, how do you combat zoning for selfishness, e.g., my own one-person gas guzzler?

A: I don’t spend a lot of time on local issues. When I have, logic and data haven’t had much effect.

Perhaps you’d like to post to your WordPress blog from an app that isn’t WordPress.

I know I do. I write most of my posts in an editor (javascript + php) I’ve worked on for over ten years. Someday I’ll clean it up and post it at GitHub so you can all have a laugh. Meanwhile, it intermittently loses its ability to post straight to my blog, so I have to copy and paste the text into the WP editor. But I fixed it again today. So, here’s a tutorial for people at my level of non-technicality. (I got huge help from a post at HurricaneSoftware. Thanks!)

First, make sure that the file xmlrpc.php is installed where you’ve installed your WordPress blog software. This file comes from WordPress itself, and it should be there automatically. Check the permissions; I think it should be 644 but I am terrible at permissions.

I run my homegrown editor from my Mac, using the Apache web server that MAMP supplies. That lets me write blog posts even when I’m not online. That means the directory from which I’m running my JavaScript and PHP is on my hard drive. I keep these files in  /Applications/MAMP/htdocs/blogdraft/. (Blogdraft is the name of the folder in which my code resides.) To the web server, the address looks like this: /localhost/blogdraft/.

The operative part of this is your PHP file. Create an empty text file and name it, let’s say, postViaXmlrcp.php. For a first pass, it should look like this—and the brunt of this comes straight from HurricaneSoftware:

This PHP script relies upon another one, so you have to load it. “Require_once” will do so, and it will remember that it has done so during a session so you won’t waste computer resources reloading it every time you run this script.

You can get this script here. Right click on that link and choose “Save file as…” or however your browser puts it. Put it in the same directory as your PHP script. Make sure you name it “IXR_Librabry.php.inc.” Set its permissions. (See above.) Then leave it alone. 

7	$title=$_REQUEST[‘title’];
8	$body=$_REQUEST[‘body’];
9	$keywords=$_REQUEST[‘tags’];
10	$category=$_REQUEST[‘categoryArray’];
11	$customfields=null;

These lines read data that you’ve sent from the JavaScript that we haven’t written yet. It assigns them to some pretty obviously-named PHP variables.

Notice that we’re doing nothing with the $customfields variable. That’s because I don’t know what to do with it. I would have just deleted that line, but it scares me. And yet fascinates me.

12	$encoding = ini_get(“default_charset”);
13	$title = htmlentities($title,ENT_QUOTES,$encoding);
14	$keywords = htmlentities($keywords,ENT_QUOTES,$encoding);

htmlentities is a PHP function that makes sure that your HTML with all of its weird characters arrive without being translated into something more literal and wrong. Line 12 tells it which character encoding to use. I could have decided on one for you, but instead I’m just using whichever one you already use. We have already established I’m a coward, right?

15	$content = array(
16	‘title’=>$title,
17	‘description’=>$body,
18	‘mt_allow_comments’=>1, // 1 to allow comments
19	‘mt_allow_pings’=>1, // 1 to allow trackbacks
20	‘post_type’=>’post’,
21	‘mt_keywords’=>$keywords,
22	‘categories’=>$category,
23	‘custom_fields’ => array($customfields)
24	);

We are eventually going to be sending all of the content information to  WordPress via XMLRPC. This section packs an array (“$content”) with the information XMLRPC needs, attached to the keywords it loves. If you want to argue about it, take it up with XMLRPC.

26	$client = new IXR_Client(‘http://www.yourblog.com/myWP/xmlrpc.php’);

We now create a new client for the IXR script you downloaded. It wants to know where your xmlrpc.php file is, which should be where the rest of your WordPress files are folders are.

27	$username = “your-WP-username”;
28	$password = “your-WP-password”;

Fill in your WordPress username and password.

29	$params = array(0,$username,$password,$content,true); // Last parameter is ‘true’ which means post immediately, to save as draft set it as ‘false’

Now we’re making another array. This one includes the prior array ($content) as well as your username and password. And note the comment. Setting to “draft” is very useful when you’re playing around with these scripts.

31	if (!$client->query(‘metaWeblog.newPost’, $params)) {
32	die(‘Something went wrong – ‘.$client->getErrorCode().’ : ‘.$client->getErrorMessage());
33	} else { echo “Article Posted Successfully”; } ?>

This does the deed. No one knows how.  If it fails, it’ll pop up the error messages and kill it before it spawns evil. Otherwise, it sends back the message that it posted successfully.

You can test this PHP script by running it in your browser. If you’re running a local web server, you’d enter something like this: /localhost/blogdraft/postViaXmlrcp.php. (That’s assuming you put it in a folder called “blogdraft,” of course.) Check with MAMP or whatever you’re using for your web server for details.

But running this as-is won’t work because it’s expecting the content to be sent to it from the JavaScript we still haven’t written. So, comment out lines #7-11, and insert something like these:

	$title=”TEST TITLE”;
	$body=”<h1>Hello, world!</h1>”
	$keywords=”tag1,tag2″
	$category=array(“cat1″,”cat2”);
	$customfields=null;

Replace the categories (“cat1”, “cat2”) with the names of categories that you actually use. Also, change “true” to “false” in line #29 so you’ll just produce drafts, not actually publish anything yet.

Now when you run this PHP file in your browser ( /localhost/yourLocalFolder/postViaXmlrcp.php), if should create a draft post. Check via the “All posts” page at your WP administration page to see if the draft got created.

When it’s working, comment out the four lines immediately above and uncomment lines #7-11.

The JavaScript

I’m going to pretend that you have some HTML page that has a text box where you can enter the content of your post, a similar box for entering the title, one for entering tags separated by commas, and checkboxes that list the categories you use. I’ll also assume that you use jQuery. So, your HTML might look soomething like this:

So, roughly, here’s what’s happening:

6	<script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js”></script>

This loads jQuery from Google. Of course you could keep a local copy and include it that way.

8	function postIt(){
9	// get the title
10	var titlecontent = $(“#titlebox”).val();
11	// get the body of the post
12	var bodycontent = $(“#contentbox”).val();
13	// get the tags
14	var tagscontent = $(“#tagsbox”).val();

The postIt function begins by using jQuery to fetch the values entered into the three text areas. (Just in case you don’t know jQuery, “$(“#titlebox”) gets the element with the ID of “titlebox.” And if you don’t want to use jQuery, you can get the same result with: var titlecontent = document.getElementById(‘titlebox’).value.

16	// get an array of all checkboxes in the div
17	var checks = $(“#categories”).find(“input”);
18	// create an empty array
19	var cats = new Array();
20	// go through all the checkboxes
21	for (var i=0; i < checks.length; i++){
22	// is this one checked?
23	if ($(checks[i]).is(‘:checked’)){
24	// if so, then push its value into the array
25	cats.push( $(checks[i]).val() );
26	}
27	}

Creating an array of categories takes a little more work. Line #17 creates an array (“checks”) of all of the checkboxes in the div with the id “categories.” Lines #21-27 look at each of the checkboxes in that array. If line #23 sees that a particular checkbox has in fact been checked, then it puts the value of that checkbox into the created on line #19. (You want the value to be exactly the same as the name of the category in your WordPress installation. Also, remember that the checkbox’s value is not necessarily the same as the text displayed to the user.)

29	$.ajax({
30	type: “POST”,
31	url: “postViaXmlrcp.php”,
32	dataType: JSON,
33	data: {title: titlecontent, body : bodycontent, tags: tagscontent, categoryArray : cats},
34	error: function(e){
35	if (e.responseText.indexOf(“Successfully”) > -1){
36	alert(“Success! Post has been posted! Let the regrets begin!”);
37	}
38	else{
39	alert(‘Error posting blog via xmlrpc: ‘ + e.responseText);
40	}
41	}
42	})

Now we call the PHP script that we created above. We do this via AJAX, using the jQuery syntax, which is much simpler than the native JavaScript way of doing it. Lines #30-40  specify the communication the JavaScript will have with the PHP file.

Line #30: The “POST” here has nothing to do with posting a blog post. It’s stating what sort of transaction we’re about to have with the PHP script.

Line #31: This is the path to the PHP file we’re going to run. If it’s in the same directory as this HTML file, you don’t have to monkey with a path name.

Line #32: We’re going to pass data to the PHP script in the JSON way of expressing data.

Line #33: This creates the JSON we’re going to send. It’s all within curly brackets. There are four phrases, separated by commas. Each phrase consists of a keyword (which you can think of as being like a variable) and a value. We are free to make up whatever keywords we want, so long as those are the keywords we use in the PHP file to fetch the data that they label; see lines #7-10 in the PHP script above.

Line #44: If there is an error in the PHP, it will send back some information. There is also an equivalent “success:” function available. But I’m doing something wrong, because even when the PHP works and the blog gets posted, I still get an error message. If you go back to Line #33 of the PHP, you’ll see that if the PHP succeeds, it sends the message “Article Posted Successfully.” For reasons I don’t understand, that message shows up in the “error:” function of the AJAX. So, I check the message. If it has the word “Successfully” in it, the script alerts the user that the post has been posted. If it does not, on line #39 it posts an error message.

That’s it. If it doesn’t work, it’s because you’re doing something wrong,  starting with listening to me. Obviously I can’t help you since I don’t even know how this thing works.

Good luck!
