(1) Since some people laugh at Cardano project and it's peer review aspect, let me share a story from work for all of you
(2) There is company called Databricks and they open sourced recently a technology called: https://t.co/gpZyKKiMVD . This technology is super important

(3) In BigData delta allows one to perform DELETE and MERGE operations contrary to Hadoop + Hive where this is not possible, seeking through many partitions finding customer data to remove and then rewriting it is not only expensive as an operation but also very dangerous

(4) This promising technology is something that many companies, which have big data turn into as they need to be GDPR compliant.
(5) I was always reading and accepting all details from their website as given and the "truth"

(6) There is however an amazing Principal Developer at our company that found some of the claims from their website as dubious, e.g. ACID claims on such a distributed file system
(7) It turns out this is not the first time this company advertises something that is simply not true

(8) on another occasion this company made untrue claims about Cassandra database and this then became source of disputes e.g by dr. @martinkl - my fave expert in distributed systems
(9) All professional developers also know of course famous Jepsen tests -> https://t.co/Hsu9IJhxS0

(10) Jepsen tests are now used for many many years to validate databases - claims that vendor make against harsh reality. In many cases claims on paper never met with hard reality of distributed systems, sometimes it was a basis for vendors to fix those databases, e.g. mongoDB

(11)Why am I writing all this. IT IS TRULY an advantage that Cardano's Ouroboros went through a rigorous process of being reviewed by academics on major conferences. It is a slow and methodical process but correct one. Cardano critics have often no experience in claims vs reality

(12) Wait, does it mean it for sure will succeed and become world's financial operating system or part of it? Of course not - this post is to show you that this claim of peer reviewed approach is something to brag about - albeit of course at the end of the day - adoption is key.

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.

Java was first released in mid-1995, just 6 months before JS.

By 98, when I went to college, Java was already used for all the first level courses in the CS program.

How did it catch on so quickly (just 3 years) to shift university curriculum, which is usually so slow/behind?

I wonder why Java was so respected and JS was not? Why/how was Java already seen as such a stable and mature language?

Not just Java, other languages (like python) were also released around/near 95, and also seemed to get to "mature" respect status. much quicker.

I bring all this up because my impression of Java in 98 was that it had been around "forever" (as had C++ first developed in 79, but not standardized until 98!), but that's not. true at all. These were all new languages around the same time.

I'm sure the language designs had different merits, and the target applications meant a different perception and reception, but...

it sure seems like the industry (and academics) just decided Java and C++ were the stable mature ones and langs like JS were toys.

BTW, before you assume JS was nascent/immature b/c the web wasn't much of a thing yet, remember that JS was actually released as LiveScript on the server before it was released in a browser. So "server-side JS" was always part of the story, not just Node 15 years later in 2009.

Facebook lost another 1 million daily users in Europe and stayed flat in North America as scandals and low engagement with teens come back to bite its business https://t.co/O7tfyIw7Fd tip @Techmeme

Facebook still added 37M monthly & 24M daily users thanks to big gains in the Asia-Pacific region, but those users earn it 1/10th as much as US/Can users

The real story dragging on Facebook's share price is that yearly revenue growth has fallen from 59% 2 years ago to 33% today. It's run out of lucrative Western users and News Feed ad space.

Let's remember that Facebook doubled its security staff & cut back on viral videos/clickbait. That drags on its profits & revenue, but are crucial to society. And while Twitter shares soar, it has made no such commitments to fighting harassment & misinfo.

Last up in Privacy Tech for #enigma2021, @xchatty speaking about "IMPLEMENTING DIFFERENTIAL PRIVACY FOR THE 2020

Differential privacy was invented in 2006. Seems like a long time but it's not a long time since a fundamental scientific invention. It took longer than that between the invention of public key cryptography and even the first version of SSL.

But even in 2020, we still can't meet user expectations.
* Data users expect consistent data releases
* Some people call synthetic data "fake data" like
"fake news"
* It's not clear what "quality assurance" and "data exploration" means in a DP framework

We just did the 2020 US census
* required to collect it by the constitution
* but required to maintain privacy by law

But that's hard! What if there were 10 people on the block and all the same sex and age? If you posted something like that, then you would know what everyone's sex and age was on the block.

1/ What causes long term sustained performance in an ad account?

🧵featuring real examples 👇🏻

If you explore the source of FB ad growth and subsequently revenue growth for eCom brands it is almost never a function of iterative improvements to ad creative or tactics over time.

2/ More often it is a series of moments that unlock an order of magnitude increase in awareness, engagement, traffic and performance.

These moments can be caused by:

A single ad
A big PR moment
A breakthrough campaign
A change in market dynamics
A new product release
Etc.

3/ The problem is they are very hard to predict and create.

I’ll give you an example of a few that happened for us @QALORing that changed our trajectory (and ad account performance) each time...

4/ The first was @andydalton14 wearing a ring on @HBO hard knocks. It was the peak of the series popularity and they did a :30 piece on the ring he was wearing while playing.

See screenshot

Notice the traffic before and after the peak.

5/ This increased organic traffic let us alter our AdWords strategy, extract more post intent demand from new searchers and pull clips of the show to supplement our ad credibility.

Beautiful Story of Guruvayurappan

Poonathanam Namboothiri was a great devotee of Guruvayurappan. One day Poonthanam was going to Guruvayur Kshetram. It was night time and eventhough Namboothiri was tired he continued to walk

Suddenly some thieves came and blocked his way. Poonthanam cried for Shri Krishna to help. Thieves snatched all valuables from him, but Namboothiri holding his Bhaghavatam book called Shri Krishna to help. That time a man came in a horse back and fought with thieves and protected

Namboothiri. Poonthanam thanked Krishna for helping him from danger and said to the man that "Shri Krishna has send you here and I don't know how to thank you". The man smiled and told that he is Mangattachan, minister of samoodhiris. Poonthanam once again thanked him and

gave his ring to Mangattachan as a token of thanks and continued his journey. He reached Guruvayur early morning for Nirmalya Darshan. Temple poojari came near him and told that Guruvayurappan came in his dreams and asked to hand over the ring to poonthanam.

When he opened Kshetra Nada poonthanam was surprised to see his ring on Guruvayurappan, which he gifted to Mangattachan. He understood that it was Guruvayurappan who came as Mangattachan to protect him. This is how Bhagwan treat his devotees.

Hare Krishna

Trump is a Russian asset, a mob money launderer installed by his mob whoremasters to sow chaos and weaken the US & our allies.

EVERY SINGLE THING HE’S DONE since taking office is to achieve those purposes—that and to enrich himself personally.

[THREAD]

1/ His entire family is part of this. Melania is a fucking crook. Ivanka is a fucking crook. Junior and Gums are fucking crooks. They will all die in prison, except for Kushner, who, if he really *did* trade US intel for money, should be executed for espionage.

2/ Why do you think Trump installs uniquely corrupt & awful people to Cabinet positions? Pruitt, Zinke, Betsy, Rex/Pompeo, Wilbur "Melting Nazi Face" Ross. They are not there to serve us. They are not there to drain the swamp. They are there to BURN THE REPUBLIC DOWN.

3/ Trump steals. He takes taxpayer money—your money and mine—and lines his pockets with it. He exploits his office to make himself richer. This is all he cares about. Why are Republican citizens, you “fiscal conservatives,” not more angry about this? Riddle me THAT, #MAGA.

4/ Matt Whitaker, the human dildo and “acting AG,” was illegally installed to throw a monkey wrench in the Mueller investigation. That’s why they won’t release his financials. He’s fucking bought and sold. He’s going to prison for obstruction.

THE MEANING, SIGNIFICANCE AND HISTORY OF SWASTIK

The Swastik is a geometrical figure and an ancient religious icon. Swastik has been Sanatan Dharma’s symbol of auspiciousness – mangalya since time immemorial.

The name swastika comes from Sanskrit (Devanagari: स्वस्तिक, pronounced: swastik) &denotes “conducive to wellbeing or auspicious”.
The word Swastik has a definite etymological origin in Sanskrit. It is derived from the roots su – meaning “well or auspicious” & as meaning “being”.

"सु अस्ति येन तत स्वस्तिकं"
Swastik is de symbol through which everything auspicios occurs

Scholars believe word’s origin in Vedas,known as Swasti mantra;

"🕉स्वस्ति ना इन्द्रो वृधश्रवाहा
स्वस्ति ना पूषा विश्ववेदाहा
स्वस्तिनास्तरक्ष्यो अरिश्तनेमिही
स्वस्तिनो बृहस्पतिर्दधातु"

It translates to," O famed Indra, redeem us. O Pusha, the beholder of all knowledge, redeem us. Redeem us O Garudji, of limitless speed and O Bruhaspati, redeem us".

SWASTIK’s COSMIC ORIGIN

The Swastika represents the living creation in the whole Cosmos.

Hindu astronomers divide the ecliptic circle of cosmos in 27 divisions called https://t.co/sLeuV1R2eQ this manner a cross forms in 4 directions in the celestial sky. At centre of this cross is Dhruva(Polestar). In a line from Dhruva, the stars known as Saptarishi can be observed.

IMPORTANCE OF SATYA NARAYAN KATHA AND ITS ORIGIN.

We all have heard and read the Satyanarayan katha. But none of us dont know the original stories that Shatanand or Sadhu or Kalavati must have heard. Also, as a habit we hear or read this katha

but dont know the proper way it should be conducted.

We find its mention in Skanda puraan(Reva khand) and Bhavishya Puraan(Pratisarg parva).
Both Bhagwatam and Gita call Bhagwan Narayan as Satv or Truth. So Satyanarayan denotes this name as the one which is Truth incarnate.

The story began in Naimisharanya when Vyasji asked Sutji about a way to eliminate all the sorrows and fulfill all the desires and about who is the devta who can grant these at the same time.

So Suutji first prayed to Bhagwan Satyanarayan who is no one else but Vishnu ji.

Then he remembered all his avatars.After that he narrated the story of Narad. Once while visiting Mrityulok, Naradji was pained to see the sufferings of People around. He was deeply moved by these sufferings and wanted to know the means by which we could rid ourselves from these.

So he went to Vishnu ji and after paying his respects stood in front of him. Naradji narrated the purpose of his visit.

So Bhagwan Vishnu said to him that in Satyug and Tretayug, Bhagwan eliminates sorrow in Vishnuswarup. In Dwapar he assumes different forms to help people.
