Oops—Tracking Removed from Traas.org

Oops! Shortly after I put up the post "Ad-blockers are not evil" where I lambasted publishing sites and ad networks for tracking their users across the Internet, I realized that I was running Google Analytics. I got into the habit of adding Google Analytics to every site I build just because that's what my clients want. In a lot of cases, it really does make sense, such as if you're serving ads on your site, or need to generate certain kinds of reports.

Traas.org, however, doesn't have those needs. So I'm tracking you and your usage for no reason. I promptly removed the GA tracking code on 9/16/2015, and am now just relying on Apache's logs for metrics.

As of today, I've also removed the use of third-party CDN hosted Javascript, CSS, and fonts. Everything is now served from Traas.org's servers. For full transparency, I am using CloudFlare as a caching proxy and CDN, but as everything is served up from my domain, I feel a lot more comfortable with that.

See the new traas.org privacy policy for more info. Let me know if there are any other steps you think I should take to maximize user privacy.

Ad-blockers are not evil

Adblock Absolution

Most websites with ads suck. Modern ad-supported sites offend as much as pop-unders in the early 2000's. Between full-page takeovers, fixed-position share links that take up 1/8 of the screen on mobile phones, auto-playing videos, slow, un-optimized JavaScript from ad-delivery and payloads in the 10's of megabytes, horrendous privacy violations, and ad networks that serve up malware, the web has never been worse.

Unless you run an ad-blocker, which makes browsing the web painless. But then some would make you feel guilty for "stealing" free web content. But is it really stealing?

No. Why? Because this is the open web. The purpose of the web is that you, the user, get to consume content in any way you want, and if the creators didn't want that, they have alternatives.

Free content is a choice

Making content freely available is a strategic choice by the creator. Using advertisements for monetization is another strategic choice. In the former case, the user gains value, while in the latter, the user experience is degraded. Neither are strictly necessary.

Some creators choose alternative business models that either do not include free content or do not include traditional advertising. Two case studies:

1) DaringFireball.net: blog of John Gruber, a popular and snarky Apple pundit. His site is successful and influential, and has no ads. He does sell sponsorships, which appear as native posts on his page and in his feed.

2) Stratechery.com: deep tech business analysis by Ben Thompson. He offers a combination of free weekly articles and a paid subscription for additional daily writing.

These are two examples in a large field of possibilities. Free content with ads is not the only possible business model.

Turnabout is fair play

There are multiple ways to detect and block users that have ad-blockers. Creators have had the option to thwart ad-blockers since the first Firefox plugins became available. The majority choose not to block the blockers as a strategy, because the loss of those users would be a greater blow overall, and blocking the blockers is seen as an aggressive stance by many users.

That being said, the creators are free to either block the blockers or serve alternative content to them, but they choose not to.

Ad networks and privacy

The greater issue for many users, myself included, is tracking. Most ads come from a small number of ad networks which are present on many different sites. These networks track your usage, so that if you are looking at a product on one site, you'll see advertisements for that sort of product on many other sites across the web.

The ad networks track users invisibly and without the user's consent. The content producers argue for the legitimacy of this tracking, because it is part of the implicit contract between a site creator and its users. That's a load of crap. The common user doesn't have the technical education to understand what's happening behind the scenes. And even if they are sophisticated enough to block third-party cookies, that doesn't prevent browser fingerprinting, Flash-based super-cookies, use of the new HTML local storage API, etc., which are all much more sophisticated, complex, and hard to prevent.

The way the open web is supposed to work

This is going to get a bit technical; I want to explore the role of the web browser with respect to content on the web.

A web browser is an HTTP-enabled user agent that renders HTML, CSS, and JavaScript content into a form that the user can understand, read, and interact with. According to RFC 1945: Hypertext Transfer Protocol &mdash HTTP/1.0 defines the user agent as:

The client which initiates a request. These are often browsers, editors, spiders (web-traversing robots), or other end user tools.

The CSS 2.1 specification's definition is similarly open:

A user agent is any program that interprets a document written in the document language and applies associated style sheets according to the terms of this specification. A user agent may display a document, read it aloud, cause it to be printed, convert it to another format, etc.

Traas.org on a browser that doesn't support CSS and JavaScript

In other words, the browser is a virtual "agent", or piece of software that performs tasks on behalf of the user. The agent's decision to not render certain HTML elements or execute certain pieces of JavaScript can be a positive thing. The browser makes all sorts of decisions on what to render based on the user's needs, such as hiding elements in responsive web sites when the viewport is too small, or downloading higher-DPI assets for higher-DPI screens.

Some user agents aren't capable of viewing modern ads. If a user of NCSA Mosaic browsed a site containing HTML5 banner ads in an iframe using ad-network supplied JavaScript, the ad would not render, as the browser does not support any of the technology mentioned. It would likely render the content from many sites, but it would fail at serving ads.

Again, from the CSS 2.1 specification:

The inability of a user agent to implement part of this specification due to the limitations of a particular device (e.g., a user agent cannot render colors on a monochrome monitor or page) does not imply non-conformance.

UAs must allow users to specify a file that contains the user style sheet. UAs that run on devices without any means of writing or specifying files are exempted from this requirement.

The user agent MUST provide ways for users to override the entirety of the styles on a web site! That is necessary for standards compliance! This puts an onus on the users' ability to choose which content to display and how.


The user chooses a user agent to decide on his behalf what content and functionality he wishes to prioritize. This could be a browser with an ad-blocker, a read-later application, a text-based web browser, an RSS reader that supports "mobilization" of content, or any number of other configurations. These are all fine. You don't need "adblock absolution." If a creator puts his work on the open web, making no effort to restrict consumption, you are under no obligation to view the ads on the site, submit to invisible tracking, or consume the content under any condition other than your own. Conversely, the creator is free to block ad-blockers, put content behind a paywall, ask users for donations, etc.

Rackspace's Managed Cloud page viewed through the pinnacle of human achievement

The popup blocker did not doom commercial web ventures. Advertisers moved on to ads that users found less objectionable. which adblockers (currently) can't target Certain classes of ads, such as sponsorships and native advertising, These are less obnoxious, and some studies say are more effective.

Finally, without the freedom to modify the way web content gets displayed on your browser, the world would never have the best browser plugin ever: Cloud to Butt Plus.

Exodus from Blogger

Bye, bye, Blogger!

Today, I'm free from Blogger. No longer must I maintain the nasty hacks that make blog.traas.org work. I'm free.

As I mentioned in a previous entry, I'd like to reduce my dependency on Google Apps. Writing a static blogging engine took longer than I thought. Actually, I finished the code months ago, but I was too lazy to clean up the garbage code that Blogger's editor generated and convert into Markdown.

The thing that finally got me off my butt was some weird server flag that caused a recent build of Chrome to try using HTTPS with *.traas.org, whilst Blogger does not support HTTPS.

If you subscribe to my RSS feed, nothing should change. The redirects should just work for you. Cacheing is slightly wonky, with my application cache, server cache, and CDN often acting strangely with each other.

Also, the convention common on static Markdown blogs of adding '.md' to the page URL listing the Markdown source is implemented here.

Feel free to report any bugs. Thanks in advance.

Planning My Exit from Google Apps

Today, Google announced an enhancement to Google+ and Gmail that I think is a step too far.

It sounds innocuous and even helpful. If you use both Gmail and Google+, people who can see your Google+ profile will soon be able to email you directly from your profile. It's handy, because you don't need to manage your own list of contacts; if you can encounter the person on Google+, you can send them a message.

Some people have objected on basis of privacy violations:

This is a fucking mess. Google just made it really easy for strangers to email you https://t.co/uX4gQHmr3i

This is my primary objection to Facebook, and why I've refused to use it as a medium for communication: it has become the primary mode of exchange between a large percentage of people. To many friends and family, Facebook is the Internet, and they never leave it's walled garden. They coordinate events and meetups exclusively on Facebook, and thus people without a Facebook account are barred from entry into these events. I literally haven't heard from many of these people in 6 or more years; they no longer use email or SMS.

I'm not arguing that de facto protocols should never change, be augmented, or be replaced. I argue that the primary channels of communication must remain open. Facebook is not Open. Google+ is not open. I cannot make an implementation of Facebook myself, and communicate with Facebook via published protocols. Google+ is no different. Gmail, a proprietary product that adds functionality on top of email, enables me to communicate to users of Hotmail, Yahoo Mail, or any other service that implements the Simple Mail Transport Protocol defined in RFC 821 in 1982. But if Google is trying to direct people away from using email addresses, and instead make Gmail the messaging tool for Google+ users, I want out.

This is going to be a long process. I rely on Gmail for all https://traas.org email for my family. I rely on Google Calandar to keep my family organized. I'm using Blogger to write this blog post. I use Google+ to complain about gadgets. I use Google Drive to store and edit documents and notes. I use Google Voice to have a portable phone number and voicemail that isn't crap. I buy a new Android phone every year.

Google+ and Blogger will be the first to go. I've already disabled the Google+ comments on this blog. I'll be looking to migrate to something Python/Markdown based for blogging. On Google+, I will remove all my circles and posts. I will use it as an identity to improve the SEO of my website, and nothing more.

I won't be leaving Android, because there is no other open-sourced mobile OS that's gained any traction. I will minimize my use of Google services on the platform, to aide in my ability to switch to a different platform if one arises. iOS is not an option for me. I find the walls of its garden too high.

Gmail will be tough. Real tough. It offers a number of features that are non-negotiable, including great filtering, labels instead of folders, two-factor authentication, and first-class Android and iOS apps. I don't know what I'm going to do here. I'd like to switch to something that makes PGP easier, if possible.

I'm not surprised. Google canned XMPP support when they rebranded Google Talk as Hangouts. I understand extending the protocol to add capability; that's healthy. But not maintaining compatibility with a protocol used by a lot of platforms and blessed by the IETF as a mechanism of interchange between instant messaging frameworks is negligent at best, and hostile at worst. I accepted, once they did that, that they would eventually cross one line too far.
