ZOMG! You Stole My Code!

While the GPL is pretty clear about this, and my personal moral code is as well, the topic today is not about the question of is it right to resell someone else’s work, but what do you do when someone’s reselling yours?

This happened to my friend not too long ago. Someone else took her theme and was reselling it and you either already know who it is or you don’t, it doesn’t matter for the sake of this story. Now, the issue was not if they could resell it, we all agreed they could. The issue was how they resold it. That is, they took her images, much of her ad copy, and resold it, presenting it as if it was their own code. And that was, we all agreed, wrong. That’s fraud, in my eyes. You’re taking someone else’s work and claiming ownership of it. But. That wasn’t my fight, it was my friend’s, and all I could offer was some moral support and connections.

But when this happens to you, what do you do?

First, don’t type angry. It’s okay to type while you’re mad, but if you’re like me, and your skin heats up when you’re angry and you get all green and violent (I type really loudly), it’s probably a good moment to step back and think about why you’re angry. After all, GPL says this is allowed, right? I get mad because of perceived ownership. It’s one of my things. You should never claim to be something you’re not and you shouldn’t sell something that isn’t yours.

And that’s the angle I’d use to approach the situation. I would find the person, ping them privately if possible (almost everyone has a contact page these days) and ask them if they could change the wording to make it clear that this isn’t their code, it’s mine, and they’re using and providing it without the support of the original author. That’s what my friend did, and that’s also what the other people whose themes were being resold did. They pointed out that the reselling was confusing to the customers, and the customers got an unlicensed product.

What if that fails? Well. Now it’s messy. Legally if they’re taking my content and putting it up on their site with verbiage that implies it’s theirs, I have a DMCA takedown right. My content is all under copyright (I have not, nor will I any time soon, chose to go copyless) and I use the CC BY-NC-SA 3.0 license, so if you use my content, wholesale, without attribution, you’re stealing. But this isn’t about my content, it’s my code, and all my code is released GPLv2 (unless otherwise noted). That means in order for me to come up and tap your shoulder, you have to take my code and my content.

Boy this got complicated. But if I ping you and say “Hey, bro, not cool.” and you ignore me, or tell me to sod off, I’ll come back and ping your webhost. “Hi, this guy is stealing my content. I asked him nicely to stop. Here’s a copy of our conversation.” I should note, none of the times I’ve ever had to do this have gotten past this step. The hosts have always stepped in, poked the perpetrator, and that was that. The times I was the bad guy (reprinting news articles), the content owners have only ever had to ask me to take it down. It’s never gotten past me.

Well okay, so what happens if the host says “Tough luck” or “We agree, but we can’t do anything without a takedown notice.” Now you bring in the law and file a DMCA (Digital Millennium Copyright Act) take down. DMCA is a U.S Copyright Law covering intellectual property. Your blog posts and ad-copy are your intellectual property. This went to a pretty dark place, didn’t it? I mean, I hate the DRM with a passion, and I freely give away my stuff, so let’s stop talking about the legal stuff. You can look it up on your own if you really want to know how to file all that.

Most of the ‘handling’ of someone who steals your stuff isn’t even the legal hassle, anyway. It’s just the pain of getting in touch with them, explaining the situation, and getting it sorted. And the headaches come from having to explain over and over that you’re not mad (though you probably are) and you just want them to stop making it look like they’re you, please and thank you.

Okay, so how might I justify selling someone else’s theme or plugin? I would sell a service. It’s really that simple. I would sell the downloading, installing, configuring, and tweaking of the product. I would charge them the raw cost of the product AND give them the license information (it’s their now). I may charge them for some ‘placeholder’ text to import via the WP importer, and to import it. Certainly I would charge for some training on how to do this going forward. But the thing I wouldn’t do is actually say “This is our plugin” or “This is my theme.” Because it’s not.

I’m just making sure you can have the theme better, faster, and easier. Plus now they can upgrade and I can go to Fiji!

Migrating A WordPress Site With wp-cli
This is … crazy simple. I wanted to move a site from ipstenu.org to ipstenu.com (yes, I own that too). While ipstenu.org is a Multisite network, ipstenu.com is where I put a ton of add-on domains. I was moving a site over and, as it was WordPress, did it in a matter of minutes.

Add the domain to the … domain

Since I don’t care to have multiple hosting accounts, and I’m the only one with SSH/FTP access, it’s safe enough for me to do this. There is a risk when you share multiple domains in one hosting account, that if one gets hacked they’re all vulnerable, but I consider it low in my situation. Every plugin is vetted, every file is checked, and then I went and gave each add-on it’s own FTP account. Neurotic? Thy name is me.

Anyway, I add the new domain to my hosting where I want it.

Create the new DB

I have to make a new database, and generally a new DB user, on the server too.

Export!

On existing hosting, I do this:
```
wp db export
```
That gives me my SQL file, thanks to WP-CLI. It’ll be named example_com.sql and will sit in my folder with .htaccess and everything else.

Copy!

I do it via SSH. I go to the new location and run this:
```
scp -r olduser@example.com:path/to/files/ .
```
Since I have ssh keys set up, it’s easy. If I don’t, I’ll put in the password, but that’s straightforward.

Edit wp-config.php

Now I have to point to the new DB. Sometimes I name it the same, but usually I don’t, so I’ll edit the DB name, DB user, and password.

Import the old DB

Ready?
```
wp db import example_com.sql
```
Boom. It’s all dumped in! Only two steps left!

Search & Replace

I love this one.
```
wp search-replace example.com newexample.com --dry-run
```
I ALWAYS dryrun test it. This is a serialization safe search, so rarely is it ever going to be an issue to just run, but it lets me make sure I don’t get any wonky results. I never have, so re-run without dry-run.

Cleanup!

Delete the SQL file, delete the old files on the old server.

Drink

I moved code. That’s shipping, right? Or is it margaritas are for migrations?

Category or Tag?
Everyone in WordPress has probably heard the advice of Lorelle VanFossen on the subject of Categories or Tags. I’m sure her 2005 post will remain, forever, one of her most popular posts, much like mine about why you shouldn’t use Multisite will be one of mine. And why is that? Well it’s simple.

She’s right.

She gives information in a clear, direct, concise way, and she’s right. She will always be right. No, sorry, if you disagree, you’re just wrong. Category abuse is like menu abuse in that it confuses your readers. If you’re organizing things in too many directions at once, the sense of location is lost and no one cares anymore.

But still, people ask which do you use and where and why? For me it’s really simple.
- Categories are organized
- Tags are free form
To me that means I need to organize my posts on a site to major topics. This is a tech blog, so I’m probably going to talk about how things are and how they do it, and how you do it. That means I really don’t need much more than three categories. I ended up with five, since I decided a CPT for presentations and another for videos wasn’t really needed. Categories categorize, though. It’s simple and straight forward. A category is a room in my house.

The tags are the items in my house and they can go in any room. They’re the minor topics of my site. Like my iPad can come into my bedroom or bathroom (we all do it), the post about plugins could be philosophical or explanatory. The little things versus the big things, as it were. The tags are all those little things scattered around the site.

But what good are they to anyone? They’re both aspects of organization, and they’re both somewhat useful to find old posts, but do your readers ever use them? It’s funny when you think about how much time we spend trying to make all these aspects of our site ‘perfect’ and how few people actually use them. Like I did a study on this site for related posts. I measured, using my analytics, how many people used them to click through and came out with a resounding “Less than a dozen.”

Same general test on another site? Over a hundred. And on that site, no one clicked on tags. They don’t really here either, but since I use categories to organize ‘sections’ of the site, those get used a lot everywhere. And if you can’t tell, this is all a lot of work. You’ve got to work hard to make the site flow right for your users and visitors. For your product, you have to consider what you’re sharing and selling, and how people logically get around. You need to study, watch, and experiment.

The real answer to category or tag is, of course, what works for you. But when you’re starting out, listen to Auntie Lorelle.

I Don’t Care If You Use Multisite

I love Multisite. I think it’s awesome. It makes my personal life way easier, it helped me write a book and get a job, and it’s a totally cool aspect of WordPress that is still underdeveloped but a very hard worker. Multisite could be so much more, and it’s still that new kid on the block, but it’s growing every day.

When I tell people over and over again that they shouldn’t use WordPress Multisite, I do so knowing there’s a good time to break every reason I said not to use it. After all, why not use it?

But there’s one big question I don’t answer in the WordPress forums anymore, and that is “Should I use WordPress Multisite?” Oh I may clarify specific moments in what I said in other places (like you can duplicate content, but I don’t believe you should), but I won’t get into conversations of “Is this a good use case?” The reason why is that I cannot tell you, quickly, if you’re a good candidate for being a WP Multisite Admin, nor can I glance and say that your situation and environment is perfect for multisite. And the reason for this is that Multisite is complicated.

Actually that’s wrong. The reason is I don’t know, and neither do you.

Do you remember, way back when you started with websites, and you first looked at WordPress and asked yourself “Is WordPress right for me?” Someone probably said “It can be.” or “Maybe.” Oh I’m sure someone said “Of course!” And another person said “No way!” But the point of all of those answers is that it depends.

When you consider using Multisite, or WordPress (or anything) for that matter, you should take stock of what you want to do. Does the product, natively, support those things out of the box? Do people complain that doing something is really hard? Do people say it’s weird, but works? Do people suggest plugins? None of those things are reasons to not use the product, whatever it is, but it’s getting an understanding as to what world you’re stepping into that is important.

But I know, I just know, one of you will post a comment here “Mika, I just want to know if I should use Multisite! Please tell me!”

No.

It takes me about an hour to determine if you and your current site are a candidate for Multisite (and yes, I have rules). Then there’s another two to three hours going over your specs (and probably pushing to get more details) and making sure this can’t be done easily with a standard WordPress install, that it can be done with WordPress, if there are extant plugins, and if there’s custom work that’s going to be needed.

Basically it’ll be about half a day spent to give you the answer you deserve, and even then, it’s not going to be the full answer because you’ve probably forgotten to tell me something like “I need non-logged in users to be able to upload files.” or “This will be on Windows IIS.”

Hopefully at this point you’re thinking that’s fair of me. Four hours of my time is worth around $1000 USD (my going rate is $250/hour when I’m available, which is rare), and while I’d be happy to do a flat-fee for that sort of thing, no one in the history of ever has come to me with a clean and precise list of what they need and why and how they plan to grow.

Which brings me back to why I just can’t do this anymore. I just don’t know. I don’t know you, I don’t know your skills. I don’t know the skills of your users and I don’t know your future plans. I don’t know if you’ve compared the options yet. I don’t know your feelings about custom code and a lot of plugins. I don’t know your requirements. I don’t know if you want to have multiple sites with no admins, or a network with a hundred super admins (please don’t do either of those things). I don’t know your SSL requirements, your domain mappings, your servers, or your host. And because I don’t know those, I can’t answer the question fairly.

I don’t care if you use it or if you use multiple separate sites. I do care that you understand that multisite is complex and I care a great deal that you’ve researched your options. I care that you ask questions like “If my database gets too big, can I split it with Multisite?” (Yes, use HyperDB or SharDB.) I care that you consider “Is a custom post type slower or faster than a separate site on a network?” (Neither, as it happens. They’re about the same.) I get really happy if you ask specific questions, actually. You know, the ones that tell us you’ve looked into this and thought about it.

The answer to “Should I use Multisite is?” is a question.

“Are you prepared to use Multisite?”

Embedding Videos from TVGuide
This one goes out to my fellow fansites.

There are a lot of you guys who use WordPress (probably that’s my fault) and like me, you bash your head in when a news source makes a video embedable, but only if you use their code. Why is this a problem? Most of us like using WP’s visual editor, and that means we have to switch to text mode, paste this in, and then never ever ever visit that page in the visual editor again:
```
<script src="http://player.ooyala.com/player.js?width=600&amp;amp;video_pcode=VlajQ6DTdv9-OYPHSJq6w4eU0Bfi&amp;amp;embedCode=NwdzM3aDp4BB3-MEdPemlMJK5XH7ZVdn&amp;amp;height=337&amp;amp;deepLinkEmbedCode=NwdzM3aDp4BB3-MEdPemlMJK5XH7ZVdn"></script>
```
Augh!

In part this is because WordPress uses TinyMCE for editing GUI-like, and switching between visual and text mode kills things. But on the other hand, how come we can just paste in a YouTube URL and that works? Well it’s a magical thing called Embeds, and basically WordPress sees that URL for YouTube and knows “OH, I should be a video and YouTube has a special code on it’s sever to tell me how to display it! Yay!”

Not everyone has that. TV Guide, CBS, etc. I’m looking at you. Where this makes sense is where they do not want you to embed a video because they want the traffic to themselves, which is fine. We can link. But where it’s daft is when they make it embeddable, give you that link, but it’s flipping ugly and can’t be used in the visual editor!

For TV Guide, at least, there’s a fix. Ooyala Video Browser.

While the search function doesn’t work ‘great’ right now, probably because I’m searching for their videos with the wrong keywords, but still I was able to embed a video like this:
```
[ooyala code="NwdzM3aDp4BB3-MEdPemlMJK5XH7ZVdn" player_id="undefined"]
```
The ‘code’ is the ’embedCode’ from the embed they gave me before.

I can also use this:
```
[ooyala code="NwdzM3aDp4BB3-MEdPemlMJK5XH7ZVdn" player_id=&"VlajQ6DTdv9-OYPHSJq6w4eU0Bfi"]
```
Using ‘video_pcode’ for ‘player_id’

So this wasn’t super obvious, and personally I would love it if Ooyala had an oembed and then a ‘share this on WordPress’ link for things, but seeing as Automattic (and Pete! Hi Pete!) helped with the plugin, this may be as good as it gets for now. Maybe they could marry it into the Media Uploader, below ‘Insert from URL’ – have ‘Insert from Ooyala’. Dreams. I haz them.

There’s a lot to this plugin that I didn’t need, though. After all, since I don’t have an account, I don’t need all the search stuff, so I stripped it down to just this (which is an mu-plugin):
```
/**
 * Ooyala Shortcodes
 * Usually for crap like TV Guide
 * Example: [ooyala video_pcode="VlajQ6DTdv9-OYPHSJq6w4eU0Bfi" width="222" embedCode="NwdzM3aDp4BB3-MEdPemlMJK5XH7ZVdn"]
 */
add_shortcode( 'ooyala', 'ooyala_shortcode' );

function ooyala_shortcode( $atts ) {
	extract(shortcode_atts(array(
		'width' => '500',
		'video_pcode' => '',
		'embedcode' => '',
		), $atts
	));

	$width = (int) $width;
	$height = floor( $width*9/16 );
		
	if ( !is_feed() ) {
		$output = '<script src="http://player.ooyala.com/player.js?video_pcode='.$video_pcode.'&amp;width='.$width.'&amp;deepLinkEmbedCode='.$embedcode.'&amp;height='.$height.'&amp;embedCode='.$embedcode.'"></script>';
	} elseif ( $options['show_in_feed']  ) {
		$output = __('[There is a video that cannot be displayed in this feed. ', 'ooyalavideo').'<a href="'.get_permalink().'">'.__('Visit the blog entry to see the video.]','ooyalavideo').'</a>';
	}
	return $output;
}
```
And that is that!

Not The Bug I Expected
“Comments aren’t working,” he said and I winced. I hate when people say ‘broken’ or ‘not working’ because I don’t magically know what they mean by ‘working.’ But this guy was a coworker whom I like and trust so I asked what he meant by not working, and he said “When you enter a comment, the page reloads, but there’s no comment.”

“Okay,” I muttered to myself. “Touché, Mika.” Because that, indeed, was ‘not working.’ We turned on debugging and got a strange error:
```
WordPress database error: [Duplicate entry '0' for key 'PRIMARY']
INSERT INTO `wp_comments` (`comment_post_ID`,`comment_author`,`comment_author_email`,`comment_author_url`,`comment_author_IP`,`comment_date`,`comment_date_gmt`,`comment_content`,`comment_karma`,`comment_approved`,`comment_agent`,`comment_type`,`comment_parent`,`user_id`) VALUES (507,'lori','admin@example.com','','12.248.40.138','2014-02-07 23:07:08','2014-02-07 23:07:08','test',0,'1','Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:26.0) Gecko/20100101 Firefox/26.0','',0,1)
```
And then it was a mess of ‘Trying to get property of a non-object…’ and ‘headers already sent.’

After some kicking of the usual suspects (reinstall WP, remove plugins, theme, etc) I realized I was stupid and the problem was that the table wasn’t updating the primary entry. It should start at 1 and move up to 2 and so on. Since everything else was working, I compared the table to a working one … and they were not the same. Here’s a good one:

There’s had comment_id as the name, and the rest of the values were blank. So I restored the values and it worked! Except … I was getting a new error.
```
Notice: Undefined property: stdClass::$comment_ID in /home/wp-includes/comment.php on line 155

Warning: Cannot modify header information - headers already sent by (output started at /home/wp-includes/comment.php:155) in /home/wp-includes/pluggable.php on line 896
```
I stared at that for a moment and after I had given up and proposed we reinstall WP and copy tables over, my brain kicked in and I said “Wait a second, isn’t that comment_ID and not id?” I changed it on a whim and shouted “HOLY **** I AM GOOD!”

Yes, it was in all caps. Yes, it was said to my coworker, who said I have his vote.

That was, by far, the weirdest error I’ve seen in months. And the moral of all this? You can’t know everything, but if you read and pay attention and are willing to experiment, you can solve pretty much anything.
