Elastic didn't really relicense ElasticSearch. It forked it.

🧵 A thread.

1/18

 There's a lot of talk in the open source community about the cost of forking.

2/18
- "Forking is best avoided."

- "Forking is a last resort option."

- "Forking is like a nuclear weapons. It's a defensive threat."

3/18
Forking is seen as impractical and extremely expensive.

And that's a Really Good Thing(tm).

It's a forcing function for figuring out solutions that are broadly acceptable across the community.

4/18
The thing is, the cost of forking is mostly a function of three things:

1⃣ the size of the community that you can bring along with you,
2⃣ whether you need to rename your fork (who owns the trademark), and
3⃣ how much infrastructure you need to rebuild.

5/18
When that "community" is your employees, when you own the trademark, and control the infrastructure, then forking is really cheap. You just tell your employees to now contribute to your new fork, and you're done.

6/18
So the whole forcing function that the threat of forking has on the community is essentially lost. You don't get your way, and you fork.

7/18
Of course, with GPL, you can't just fork and close-up the source code, unless you've secured re-licensing right from all of your contributors. This is why the GPL+CLA combo is so prevalent with FOSS vendors.

8/18
With permissive licenses, there is no such need. You can literally embed the software into anything that is proprietary. As long as you give proper attribution and keep the open source license around FOR THAT PART OF THE CODE ONLY.

9/18
No one can stop me from forking Node today and releasing it as proprietary software.

10/18
What I can't do however is:

1⃣ move all of its community to contribute to my proprietary fork overnight,
2⃣ use the "Node" trademark, and
3⃣ leverage all of the existing infrastructure that isn't mine.

11/18
So the problem with Elastic forking ElasticSearch isn't the CLA, or its new license.

It's that it:

1⃣ *is* the community,
2⃣ owns the trademark, and
3⃣ controls the infrastructure.

12/18
So from the very start, none of what would have made forking costly was ever an issue for Elastic. At any point in time, Elastic could have forked at practically zero cost.

Of course, that's a powerful weapon and an incredible power imbalance in a community.

13/18
A key element of community stability (the shared threat of forking) was lacking from the get go.

The lack of open governance, of community trademark ownership, and of a genuine community of contributors beyond Elastic employees, are at the heart of the problem.

14/18
Folks like @beep and @adactio have started calling this "nominally open source."

I think it's more "Schrödinger open source."

Despite the license, you don't really know whether it is open source or not until you open the envelope and find out the cat is dead. 😿

15/18
With that framing in mind, ElasticSearch was never really open source. It was always in this unstable, "quantic" state of being both open and close, up until a decision was made and it was no longer open.

16/18
I've said it before and I'll say it again. We really need to start looking beyond licensing to understand open source and really assess the risk of buying into an open source project.

17/18
Licensing clearly is a factor, but community health, governance, and trademark ownership are just as important.

It's time we truly recognize this.

There are only 3 real challenges to free speech at the tech level a) the need for CDNs at scale b) distortions of net neutrality c) nation-state firewalls.

All other claims are about social governance on private sites, where applying free speech doctrine is a stretch at best

Baseline free speech has expanded modestly since 1776 or whatever your reference point is.

About 20% beyond core case of government-critical speech in formally public spaces and media I'd say.

You can (for example) have more kinds of conversations in a bar without getting punched or kicked out by other patrons or management. You can teach more things in colleges than 100 years ago.

That's a genuine de facto increase in practical, informal free speech/expression.

But online free "speech" is, as @reneed has pointed out, not an expansion of free speech at all, but an expansion of reach. It is like the secondary freedom of the press to print as many copies as they can afford, not primary freedom to say what they want

If a newspaper wants to print more copies it has buy more printing equipment and front more upfront costs. Reach for a paper publication is not "free", but a function of desired circulation, which in turn is a function of demand prediction etc. But that logic is obscured online.

The YouTube algorithm that I helped build in 2011 still recommends the flat earth theory by the *hundreds of millions*. This investigation by @RawStory shows some of the real-life consequences of this badly designed AI.


This spring at SxSW, @SusanWojcicki promised "Wikipedia snippets" on debated videos. But they didn't put them on flat earth videos, and instead @YouTube is promoting merchandising such as "NASA lies - Never Trust a Snake". 2/

BREAKING: @CommonsCMS @DamianCollins just released previously sealed #Six4Three @Facebook documents:

Some random interesting tidbits:

1) Zuck approves shutting down platform API access for Twitter's when Vine is released #competition


2) Facebook engineered ways to access user's call history w/o alerting users:

Team considered access to call history considered 'high PR risk' but 'growth team will charge ahead'. @Facebook created upgrade path to access data w/o subjecting users to Android permissions dialogue.


3) The above also confirms @kashhill and other's suspicion that call history was used to improve PYMK (People You May Know) suggestions and newsfeed rankings.

4) Docs also shed more light into @dseetharaman's story on @Facebook monitoring users' @Onavo VPN activity to determine what competitors to mimic or acquire in 2013.

So is Apple's anti-theft security a wonderful boon to users?

Or is it just another evil corporation strengthening it's monopoly power?

I had the misfortune of buying a 2018 Mac Mini on ebay a few days ago. Unfortunately, it had not been wiped, and it's security defaults had never been changed.

This essentially turns it into a very shiny paperweight.

And this is where everybody jumps to blame the victim. "But everybody knows you have to make sure the seller wipes the Mac."

My how the corporate overlords have trained us to be their apologists.

To be clear, I'm a software engineer. Part of my job is supporting Mac users. Where I work, people hold on to their computers for several years generally, and the T2 chips are only a couple of years old, so I hadn't run into this situation at work.

Of course, I'd read about them, but I was confident that whatever condition the computer arrived in, I'd likely be able to deal with it.

Unfortunately I hadn't read up enough to be an expert on their T2 chip and Activation lock.

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.

A THREAD ON @SarangSood

Decoded his way of analysis/logics for everyone to easily understand.

Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen

1. Keeps following volatility super closely.

Makes 7-8 different strategies to give him a sense of what's going on.

Whichever gives highest profit he trades in.


2. Theta falls when market moves.
Falls where market is headed towards not on our original position.


3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result

He believes in a market operator, if market mover sells volatility Sarang Sir joins him.


4. Theta decay vs Fall in vega

Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.

The first area to focus on is diversity. This has become a dogma in the tech world, and despite the fact that tech is one of the most meritocratic industries in the world, there are constant efforts to promote diversity at the expense of fairness, merit and competency. Examples:

USC's Interactive Media & Games Division cancels all-star panel that included top-tier game developers who were invited to share their experiences with students. Why? Because there were no women on the

ElectronConf is a conf which chooses presenters based on blind auditions; the identity, gender, and race of the speaker is not known to the selection team. The results of that merit-based approach was an all-male panel. So they cancelled the conference.

Apple's head of diversity (a black woman) got in trouble for promoting a vision of diversity that is at odds with contemporary progressive dogma. (She left the company shortly after this

Also in the name of diversity, there is unabashed discrimination against men (especially white men) in tech, in both hiring policies and in other arenas. One such example is this, a developer workshop that specifically excluded men: https://t.co/N0SkH4hR35

NARHARI AND BHAGWAN PANDURANG/VITTHAL

Once a goldsmith by the name of Narhari lived in Pandharpur. He excelled in his craft. He had vowed not to look at Pandurang or visit his mandir ever, as he was a Shiva Bhakt.
One day, a wealthy merchant visited him.


He wanted a gold girdle studded with precious gems, to be made for Prabhu Vitthal. Narhari refused to make it as it was for Vitthal.
After many requests, he agreed to make the girdle but asked the merchant to bring the measurement from the mandir as he himself would not go there


The measurement was given n he made the girdle. When the girdle was put on Vitthal, it was loose. Narhari had to shorten it. Now the girdle became tight. So Narhari was forced to take measurement on his own. He had to go to the mandir but went blindfolded to avoid seeing Vitthal


In the Mandir, when blindfolded Narhari touched Vitthal, he felt as if he was touching Shiva with matted hair, the moon, snake in His neck and Trishul in His hand. Ecstatic with joy, he removed the blindfold to see Shiva but he found the murti of Vitthal with Rukmini there.


He realised the truth that there was no difference between Vitthal and Shiva. Narhari at once fell at the feet of Panduranga. He then took the measurement of the waist of Vitthal and this time the ornament fit the Murti perfectly.
