There are lots of problems with ad-tech:

* being spied on all the time means that the people of the 21st century are less able to be their authentic selves;

* any data that is collected and retained will eventually breach, creating untold harms;

1/


* data-collection enables for discriminatory business practices ("digital redlining");

* the huge, tangled hairball of adtech companies siphons lots (maybe even most) of the money that should go creators and media orgs; and

2/

* anti-adblock demands browsers and devices that thwart their owners' wishes, a capability that can be exploited for even more nefarious purposes;

That's all terrible, but it's also IRONIC, since it appears that, in addition to everything else, ad-tech is a fraud, a bezzle.

3/

Bezzle was John Kenneth Galbraith's term for "the magic interval when a confidence trickster knows he has the money he has appropriated but the victim does not yet understand that he has lost it." That is, a rotten log that has yet to be turned over.

4/

Bezzles unwind slowly, then all at once. We've had some important peeks under ad-tech's rotten log, and they're increasing in both intensity and velocity. If you follow @Chronotope, you've had a front-row seat to the

X : Can you apply pace layers to maps?
Me : You can but what is where evolves. However, same rules apply to things, practices, data, knowledge and ethical values. All are forms of evolving capital. In the mapping world, we refer to this with pioneers, settlers and town planners.


X : What's the robot for?
Me : Image from an older presentation slide, don't worry it has no relevance.
X : Is this linked to diffusion?
Me : Not simply. Evolution of a single component can consist of many hundreds of diffusion curves i.e. a virus diffuses but it also evolves.

X : Why have you got DevOps in legacy? We haven't even started yet.
Me : That's not my problem. I would take a look at serverless.
X : DevOps is serverless.
Me : Some of the practices maybe co-opted (see ITIL vs DevOps) but the new faction will decide what it is or isn't.

X : I also disagree with your methods graphic.
Me : Do you mean this? As applied to the following map?
X : Yes. Lean is suitable for innovation.
Me : Ah, that depends upon what you mean by innovation. If you mean Genesis then lightweight XP has it beat.


X : I disagree.
Me : Well, I've had 15 years of people telling me that Agile works everywhere or Lean works everywhere or Six Sigma works everywhere and why all the competing methods don't. I have no interest in the conversation. Use appropriate methods based upon context.

I have been a Substack and Patreon user for a few years now. And though more than one social media giant has, in recent months, expressed the desire to help writers and journalists monetise their audience, there are very good reasons to take these SOPs with a pinch of salt.

Because the reason Patreon and Substack came into existence was not the need for a new business model. It was as a cure for the old business model - an algorithm-driven ad revenue system that powered the attention economy. The attention economy turned audiences into scrollers...

We’ve spent the last ten months building #CitizenBrowser, a project that aims to peek inside the Black Box of social media algorithms, by building a nationwide panel to share data with us. Today, we are publishing our first story from the project. /1

.@corintxt crunched the numbers and found that after Facebook flipped the switch for political ads, partisan content elbowed out reputable news outlets in our panelists’ news feeds. https://t.co/Z0kibSBeQZ /2

You can learn more in our methodology, where we describe how we did this and what steps we took to ensure that we preserved the panelists' privacy. https://t.co/UYbTXAjy5i /3

Personally, this project is the culmination of years of experiments trying to figure out how to collect data from social media platforms in a way that can lead to meaningful reporting. I’ve described a couple of highlights below 👇 /4

My first attempt was in 2016 at Propublica, when I was working with @JuliaAngwin . We were interested in seeing if there was a difference in the Ad interests FB disclosed to users in their settings and the interests they showed to marketers. /5

Ok I was wrong about theHouse. 2 years of legislative gridlock = not fun. Few bills passing.

Control of the House is useless when it comes to keeping Trump from declassifying all the SpyGate docs. Or stopping an Inspector General from releasing a report.

Trump still gets control of judicial appointments so we can expect another 100 judges over the next two years. This time there’ll be no McCain or Flake playing the Maverick role with their swing vote.

That new margin in the Senate is huge if another Supreme Court seat comes open.

So from the responses I’m getting, people seem to think if Trump declassifies the Spygate stuff now, nothing happens.

Are you under the impression federal prosecutors have to wait until CONGRESS finishes an investigation and makes criminal referrals before the DOJ can act?

There’s a federal grand jury on McCabe right now. Did Congress ever finish it’s investigation and make a referral to the DOJ against him?

No.

BUT INSPECTOR GENERAL HOROWITZ DID. On finishing his McCabe leak report.

Funny how nobody remembers that.

Published a new essay: The red flags and magic numbers that investors look for in your startup’s metrics – 80 slide deck included!


This was a deck that I created on my (longish) interview process with @a16z. It was a long path, starting with meeting folks at the firm 10 years ago. But the purpose of the deck was to explain how I would use my superpower in an investing context

Here's what I explain in the deck. As investors (whether angel or VC) we're often confronted with an up-and-to-the-right graph. Is it going to go up? Or down?


One solution to forecast these growth curves is the Growth Accounting Framework, where you add up New+Reactivated and subtract churned users. In each time period that gives you the difference in monthly actives.


The problem with this is that it's a lagging metric, not a leading one. We need to go one level deeper and look at the underlying loops that drive these numbers, to understand the quality.

How to sell option?
Here let me explain through simple math.
Say BN at 30000
30000 straddle trading at combine premium 800 ( based on current volatility)
Put at 400
Call at 400
You don’t know direction. Sold both.

If move will not come than both will decrease gradually.

At day end it will come down to 720-740 if move will not come. Difference is your profit.

Now case 2:
Move started.
At one points combine premium will start increasing.
Say 810.
Exit immediately. No need to do adjustment.
Let market settle.

Sell again straddle once market settle.
Now repeat same thing.

Straddle selling webinar over.
Good luck.

One can keep SL 550 for both strike to escape from sudden movement.

1. Let's talk about the effects of #climatechange on the world's forests, with a focus on the northwest of Canada. This is also about electoral #greenwash, and my duty as public servant and right as private Canadian citizen to speak freely about what I know.

2. Why am I compelled to speak? How am I free to speak? The answer is in the federal Values and Ethics Code of Coduct (VECC).


3. It can be career-limiting to criticize government policy when you work for government. Duty of Loyalty is very, very important. However, as VECC makes clear, it is not absolute. In fact SCoC has ruled twice in favour of citizen free speech as a higher ideal. In 1985 and 2001.

4. I am therefore perfectly comfortable showing you the scary things that are happening in the North under a warming climate. A failure to meet global GHG emissions targets is hurting Canada's forests in a way we used to think wouldn't happen for decades.

5. Warming temperatures and rising [CO2] could, in theory, help green the planet with more vigorous tree growth. But that's not what's happening. Don't believe the #greenwash. The positive effects are over and it is warm enough that we are now starting the into the negative.
