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.

https://t.co/PwiRIL3v9x
5) Interesting contrast regarding "never selling users' data"
6) OK well at least Facebook developers were self aware of their public image (re: bluetooth beacons and call-logs): "Facebook uses new Android update to pry into your private life in ever more terrifying ways - reading your call logs, tracking you in businesses with beacons,etc"
7) @FTC consent decree required that @Facebook get 1A) affirmative consent before the collection of covered info 4A) create a privacy program to address privacy risks

However, docs show lead of privacy program was actively working to evade user consent https://t.co/mcXhDnSg2i
8) Another study in contrasts

@Facebook statements re: Android SMS and Call Log History
1) internal discussion Feb 4 2015
2) public 'clarifying' statement Mar 25 2018
9) Anti-competitive practices can consist of selectively blocking access to the ad network, not just user data:

@Facebook's director of platform offered to 'unblock @Tinder's monetization possibilities' if @Tinder permitted use of 'Moments' trademark:
https://t.co/VkJGD4hp5E
10) 2015 exchange re: whitelisted apps with @Lyft

Q: Are there any contracts or other steps besides whitelisting to launch a feature using the APls?

A: You don't need to worry about any contracts for the api. This is a product we are testing and will be rolling out slowly.
11) Facebook rep discusses removal of 'all friends-list in V2 of Facebook API as an indirect way to drive mobile ad adoption
(NEKO is an acronym used to describe mobile app-install ads)
12) Here is the key 'pay for access' evidence that @DamianCollins hinted at in @CommonsCMS: Apps need to spend at least $250K/yr on @Facebook ads (NEKO) in order to maintain access to data. Apps that don't will have data permissions will be revoked. #antitrust #sellingdata
13) In 2012, Vine and Path were the two fastest growing social networking app competitors to Facebook. #wherearetheynow #competition
14) If you read anything, it should be the email from @Zuck on P49 laying out his vision for platform monetization and growth (echoed by Sandberg).

It most clearly lays out the strategy of the company with regards to platform API and user data:
15) "The fundamental principle that governs Platform usage: reciprocity-an equable value exchange between a 3rd party developer and Facebook" (excluding competitors)

Developers provide: or direct payment/rev sharing
FB provides: access to platform (userdata/friends)
16) Finally, some might recall this exchange between @Zuck and friend from a *slightly* older leak (2004) which illustrates that the issue of bartering access to users' information isn't a new one -- it's @Facebook's primary motivation:

I went looking for a remote-controlled power switch (the wireless christmas kind, not the modern IoT kind) and didn't find it, but I did find this thing I bought just to figure out why it exists.
It's a timer outlet, but you program it from your phone... but it's not wireless.


Yeah instead it plugs into your phone's HEADPHONE PORT


I got it on sale.
probably because iphone dropped the headphone port and they had to get with the 21st century and make it bluetooth


So inside the box is the device. it's got a little 2-prong polarized outlet with no ground.


on top is the only controls: on/off/timer.

1/ Thread: "A Silicon Valley Ponzi Scheme"

Thanks to @chamath for laying this out in Social Capital's 2018 annual letter.

I've always appreciated his outspokenness.

2/ The hardest thing for most startups today is the path to market: first finding product-market fit & a way to reach customers, then building a ruthless machine to acquire, monetize & retain them.

3/ Because of this, when the VC industry invests capital into fast growing startups today, the plurality (if not majority) of invested capital will go into user acquisition and ad spending, for better or worse— usually worse.

4/ Todays massive venture-backed advertising, sales, and user acquisition playbook has morphed into one that champions growth at any cost.

This is creating a big bill that will soon come due...

5/ Ad impressions and click-throughs are bid up to outrageous prices by startups flush with venture money, and prospective users demand more and more subsidized products to gain their initial attention.

A common misunderstanding about Agile and “Big Design Up Front”:

There’s nothing in the Agile Manifesto or Principles that states you should never have any idea what you’re trying to build.

You’re allowed to think about a desired outcome from the beginning.

It’s not Big Design Up Front if you do in-depth research to understand the user’s problem.

It’s not BDUF if you spend detailed time learning who needs this thing and why they need it.

It’s not BDUF if you help every team member know what success looks like.

Agile is about reducing risk.

It’s not Agile if you increase risk by starting your sprints with complete ignorance.

It’s not Agile if you don’t research.

Don’t make the mistake of shutting down critical understanding by labeling it Bg Design Up Front.

It would be a mistake to assume this research should only be done by designers and researchers.

Product management and developers also need to be out with the team, conducting the research.

Shared Understanding is the key objective


Big Design Up Front is a thing to avoid.

Defining all the functionality before coding is BDUF.

Drawing every screen and every pixel is BDUF.

Promising functionality (or delivery dates) to customers before development starts is BDUF.

These things shouldn’t happen in Agile.

⚡️🧠Impact = Environment x Skill

A framework for making big career decisions by @iambangaly (Reforge Partner, Former Instacart, Instagram)

Full post -> https://t.co/dU0l7e0BWR

🧵 Thread...

1/ Career decisions about your next role/opp are the most impactful decisions you might make in your career. As an operator, all of your eggs are in one basket at a time, and we get a limited number of swings at the plate. So getting good at these decisions is important...

2/ At FB, Bangaly managed Rotational PM's. At the end of a rotation, he'd have the same convo: How are you going to choose your next rotation/role?

As a result, Bangaly got a lot of reps guiding this type of decision and created a framework to help with it...

3/ The framework is Impact = Skills x Environment

The goal is not to try and boil this type of decision down to a spreadsheet of inputs that spits out the answer, but rather it helps with 4 things...


4/ It can help with:

- Identify individual variables that are inputs into the decision.
- Evaluate each individual variable in a structured way.
- Understand the relationship between each variable.
- Narrow the decision down to the most important variable

EV Battery overview
Batteries are the key differentiator between the various EV manufacturers. The amount of energy stored in the battery determines the range of the EV, thought to be a major limitation on EV sales.


Consumers tend to worry that an EV with a range of 80 to 250 miles on a single charge would be inconvenient for long trips due to the time it takes to recharge the battery. Commercial batteries need to ensure there is quick recharge and less time between charges


The lithium-ion battery is important because it makes EVs expensive than ICEs. Battery costs per kilowatt-hour (kWh) declined from roughly $1,000 per kWh in 2010 to $227 in 2016


Lithium-ion batteries made up 70 percent of the rechargeable battery market in 2016
BNEF projects that global production capacity for lithium-ion batteries will increase from 103 gigawatt-hours (GWh) in the first quarter of 2017 to 273 GWh by 2021.


The battery manufacturing supply chain has three main parts:

cell manufacturing,

module manufacturing, and

pack assembly.

How you can filter stocks for Intraday trades - 🧵

As a kid, we would do homework before school the next day - you have to do homework here too. A specific sector performs on a particular day and studying things a day before will help you spot that particular sector. (1/11)

To prepare for the next trading day, you got to check the Index charts of all sectors. You got to keep an eye on a specific Index if you see a few factors:

- If any Index closed exactly at the resistance, you can get a trade on either side on the next day. (2/11)

- If it gave a rejection candle at resistance.

- If any Index closed exactly at support, you can get a trade on either side the following day.

- If there was a bullish signal at the support.

- If any Index gave a breakout or breakdown and then gave a good closing. (3/11)

- If any Index has taken support at 50 or 200 EMA.

Once you spot the Index, look at all the stocks in that particular Index. Pick at least 3-4 stocks from that Index and add them to your watchlist for the next day. It's ideal to check both higher and lower timeframes. (4/11)

What you should do next day? (When I am unable to check Indices and stocks a day before, I sometimes directly start with this process.)

- Start with checking the top gainers/losers list. I observe market from 9:15 to 9:45am to check the sectors performing well on that day.(5/11)

Did you know?
Ahilyabai Holkar was one of India's
greatest women rulers of all time.

Ahilyabai was Born on May 31,1725 in the village of Chondi,Jamkhed distt,Maharashtra to a man named Mankoji Shinde,who was the Patil(Chief) of a village and a member of proud Dhangar Community.


Despite the fact that girls' education was a farther dream in those days, Ahilyabai was homeschooled by her father.
Ahilya didn't belong to any royal family but in a twist of fate she is still remembered as one of the most revered Queen in the history.


While they were living their humdrum lives, one day Malhar Rao Holkar, commander of the Peshwa Bajirao & Lord of the Malwa stopped in Chondi on his way to Pune, where he couldn't help but notice a young 8yrs old Ahilyabai in the temple service feeding the poor & hungry.

He was so impressed by the sheer innocence&beauty with simplicity character of Ahilyabai dat he asked her hand in marriage for his son Khanderao Holkar.Just like that she got married to Khanderao in 1733 at a tender age of 8&became a bride of esteemed Maratha community of Holkars

But destiny had something else in store for her as her husband died in the Battle of Kumbher in 1754 leaving her widow at 29.Distressed Ahilyabai was to commit Sati when her father-in-law Malhar Rao refused to let it happen.

So when it first appeared in Normandy, the Sherman Firefly and it's meaty 17 pounder represented an ideal combo of reliable chassis, great gun and devastating firepower right?

Ummm...

Truth is a bit more complex. /1
#WW2 #SWW #History


Deliveries of Firefly to units only commenced in April 1944,
just a few weeks before Overlord & left minimal time for familiarisation.

Armoured Regiments mostly utilised Fireflies on a basis of 1 per troop of 4 tanks. /2


Finally each armoured regiment troop had access to integral, meaty, anti-tank firepower capable of dealing serious damage to any German AFV likely to be encountered. /3


The dual purpose 75mm gun was quite capable of laying down a reasonable HE shell or AP round for dealing with Panzer III or IV.

Firefly's 17 Pounder had.... problems with HE, but excelled at tank killing. So Tigers and Panthers would need to be wary. /4


Firefly's design history dated back to March 1943 when the General Staff published "Policy on Tanks" which effectively stated the majority of tanks should have a good HE weapon and...

Thrikkangode Sree Randu Moorthy Temple
Ottappalam, Kerala. 🚩
#keralatemples

This is very unique temple as Shiva and Vishnu both are in the “linga” form in the same Garbhagriham. The Srikovil is in a circular pattern. Temple's Prathishta was done by Parasurama.


Mahadeva and Maha Vishnu in the same Srikovil is very rare Prathishta, but poojas are done separately Dhara is done to Maha Vishnu here. People suffering from “KAIVISHAM” and mental illness are fully cured on drinking a medicinal herb supplied by a nearby family here.


The root of the banyan tree around the Ayyappa Sannidhanam is said to have great powers for skin ailments.

Very ancient temple but was covered with forest for many years.
Later two persons Chakki and Chaathan, while cutting trees their axe hit on the nearby
@SriramKannan77


Vigrahams and it suddenly started bleeding. Later Devaprashnam was held and thus found out that these were murthy's of Shiva and Vishnu which was worshipped long back. And thus temple is constructed here.

Surendra Ananth @surendraananth, you violated my conditional consent. I assented to unprotected intimate relations with you on the STRICT condition that you tell me if you have relations with anyone else. You failed to do so, and I became ill as a direct consequence.

You refused to reveal your own STI results to me, but claimed to others they were negative and alleged I had multiple other partners, slut-shaming me. You gaslit me saying you had told me about your other partners.

You called up @justice_sisters and @SistersinIslam to tell them I was crazy, jilted. You rebuffed attempts to organise a community mediation so we could address matters. You said I was crazy for speaking to your boss and father in an attempt to keep other women safe.

You have a PATTERN OF BEHAVIOUR of misogyny, harassment and sheer disrespect for women. This was sent to a friend of mine who has never expressed interest in you and has a partner.


You think women are playthings, notches on the bedpost. You, @surendraananth, are no human rights advocate.
