Last talk about Securing Democracy at #enigma2021: @jackhcable speaking about "THE FULL STACK PROBLEM OF ELECTION

 Let's imagine that elections use all the security measures security people have been advocating: risk-limiting audits, paper ballots, etc. Would people trust the elections more?
Jack would argue no. Most people don't understand this stuff and most of the claims people are making can't be disproven. And are massively bogus already.

Georgia did a full recount on paper ballots and it very much didn't stop people from doubting the election!
Are election security results in vain? The point of election security is to convince the loser they lost.

No! Have to focus on the whole stack, from election infrastructure to campaigns to people and mis/dis-informaton
One takeaway from the talk: the parts of the stack must work in tandem. Can't fight misinformation in a vacuum, but must build on other election security measures.
The voting process
* significant advances in recent years (e.g. paper ballots, risk-limiting audits, end-to-end verifiability)
* research needed in integrating these technologies
* expanding to mail-in voting?
But there's also internet voting
* we can't do it securely today [oh no voatz reference]
* we have to combat malware, authentication etc.
* if we could solve them, that would be great. But in the meantime voting has to be successful for everyone
* can improve accessibility through things like getting ballot online, filling it out, then returning through the mail
Election support systems
* less researched. Probably because they look boring
* Voter registration databases aren't working. Russians breached at least 2 states, targeted all 50 states
* little to no public scrutiny of these systems
* election night reporting -- this is a picture of one where there was a bug in reporting. [It was fixed but freaked a lot of people out]
A lot of the trouble with the security of election support systems is not that we don't know how to do it -- it's that we have to do it
Campaign security
* biggest unknown (see Sunny Consolvo's talk!)
* we must view campaign security as non-partisan and increase resources and services available
Public confidence
* major damage from domestic actors
* widespread mis/dis-information
* technical election security measures helps to debunk rumours floating around
Misinformation-fighting supply measures:
* platforms: downranking and deplatforming
* trusted institutions
* debunking & fact checks
Misinformation-fighting demand measures:
* media literacy
* increased civics education

[ Also note that @katestarbird will be giving a talk on misinformation don't miss it: https://t.co/a0PutRnHaI]
Let's fix election support systems!
* Much of this is applying security things we already know
[ Note: a lot of organizations have this problem 😭 ]
* engage in public research. Have a vuln disclosure policy so people can confidently help
Election security is a problem that can only be solved by working together: elections officials, security people, everyone

Next up at #enigma2021, Sanghyun Hong will be speaking about "A SOUND MIND IN A VULNERABLE BODY: PRACTICAL HARDWARE ATTACKS ON DEEP LEARNING"

(Hint: speaker is on the

In recent years ML models have worked from research labs to production, which makes ML security important. Adversarial ML research studies how to mess with ML

For example by messing with the training data (c.f. Tay which became super-racist super-fast) or by foiling ML models by changing inputs in ways humans can't see.


Prior work considers ML models in a standalone, mathematical way
* looks at the robustness in an isolated manner
* doesn't look at the whole ecosystem and how the model is used -- ML models are running in real hardware with real software which has real vulns!


This talk focuses on hardware-level vulnerabilities. This is particularly interesting because these can break cryptographic guarantees (because those are outside of their threat models)
e.g. fault injection attacks, side-channel attacks

We're kicking off the Privacy Tech session at #enigma2021 with Mitch Negus speaking about "NO DATA, NO PROBLEM—GIVING NUCLEAR INSPECTORS BETTER TOOLS WITHOUT REVEALING STATE

A nuclear catastrophe hasn't occurred... yet. So we need to stay vigilant. Nuclear inspectors go in according to treaties to check what's going on and check compliance with treaty rules.

But as sophisticated analytics become more common, states will only want to share the minimum amount of information necessary under the treaty.

But perhaps we can use MPC -- secure multi-party computation

Yao's garbled circuits were first demonstrated on the millionaire's problem -- figuring out who's richer without revealing actual amounts.

Used for other things like cryptocurrency these days.

Can we use this for nuclear inspection?

MPC can be used to compute anything computed by a computer [but it's expensive!]

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.

In more Securing Democracy at #enigma2021, @ChrFolini talking about "THE ADVENTUROUS TALE OF ONLINE VOTING IN

Switzerland is a direct democracy where citizens get to vote at least 4x/year, with a lot of mail-in voting. We have a long history of online voting.

Disclaimer: THIS IS NOT SWEDEN.

[I get the picture that @ChrFolini has had to explain the difference several times.]


Process around mail-in ballots.

[tl;dr it's very complicated and wasn't threat-modeled until recently]


But the in-person ballots are complicated, too!


Most security folks don't think that we can't make a secure online voting system.

@ChrFolini says this is because of encryption
[Note: this is not the main reason that a lot of people cite -- we're more worried about things like malware but it's complicated]

Next up in Privacy Technology at #enigma2021, Kelly Huang from @ethyca speaking about "GONE, BUT NOT "FORGOTTEN"—TECHNICAL & PRACTICAL CHALLENGES IN OPERATIONALIZING MODERN PRIVACY

Just imagine there's a global pandemic forcing everyone to stay home and buy their stuff over the internet. And you've been working on your sanitization-on-demand startup. You've got more users than you can count! ... literally, because your data's all over.

Now you're a multi-national international country with privacy issues because your information is all over the place.

Now a user writes to request you delete their data. Where is it? How do you do that? Who's responsible for privacy in your business.

How do you operationalize privacy rights?

Today in #GRAHAMNC I went to a permitted March to the Polls lead by Rev Drumwright and others. Starting at a Black AME church, Rev Drumwright started the march by asking folks what our intentions were. TO VOTE the crowd chanted. Its the last day of Early Voting in #NC.


We then marched, escorted by police, about half a mile towards the center of Graham, chanting and singing. We moved slowly, because of the many elderly folks and families with small children. Graham is a small town in #AlamanceCounty.


Alamance County is known as "No Chance Alamance" because of rampant inequality and a judicial system generally known to be hostile to Black and Brown folks, and poor white folks. We believe that we can change that at the polls this year.

As the march approached the center of Graham where a large Confederate statue is, we kneeled in rememberance of George Floyd. His neice and nephew were in the crowd.


Moments after we were done kneeling a police officer started to yell that we had to be off the street. Folks were confused because we had been escorted there and had a permit. I moved my child up onto the sidewalk. They started pepper spraying us. My child couldn't run because

NEW - on @skynews shortly:
Reliable source tells me Withdrawal Deal text contains

- No unilateral exit from backstop

- Large annexe on level playing field

.... after reporting this on @SkyNews I get a call from a different senior source that this is “spot on” and further that the Attorney General Geoffrey Cox has not pulled his punches in confirming in legal advice there is “no unilateral exit” from backstop ...

... furthermore I’m told (and this chimes with excellent Times splash this morning re Weyand) that the future partnership then takes its starting point as the activated backstop - ie UK-wide customs union-style arrangement and level playing field.

Understand that a ministerial briefing on the draft Withdrawal Agreement meant to drum up support from some trade organisations due tonight has now been postponed

All the challenges to Leader Pelosi are coming from her right, in an apparent effort to make the party even more conservative and bent toward corporate interests.

Hard pass. So long as Leader Pelosi remains the most progressive candidate for Speaker, she can count on my support.


I agree that our party should, and must, evolve our leadership.

But changed leadership should reflect an actual, evolved mission; namely, an increased commitment to the middle + working class electorate that put us here.

Otherwise it’s a just new figure with the same problems.

I hope that we can move swiftly to conclude this discussion about party positions, so that we can spend more time discussing party priorities: voting rights, healthcare, wages, climate change, housing, cannabis legalization, good jobs, etc.

IMP 🚨 INVESTIGATION

India's lockdown was called world's largest, strictest etc. @ BBC, we wanted to know how the govt planned it.

So, what're we looking at?

Govt docs that reveal every department/agency who was consulted by PM Modi before imposing #lockdown.

#Thread


How did we access the docs? Well, for months my colleague Arjun Parmar and I filed RTI applications with the relevant govt depts - State & Centre. Hundreds in fact. We then filed appeals, then filed second appeals..phew!

Background - this day last year, India had less than 600 cases and nine deaths. Some European & Latin American nations (with way higher numbers) had imposed lockdowns.

China, with thousands of deaths and cases by March 2020, never imposed a national lockdown.

One more thing - India started monitoring and preparing it's response to coronavirus from January 8, 2020. It was repeatedly mentioned that none other than PM was personally leading the effort.

Let's start with what we've got now.

India's lockdown was imposed by an @ndmaindia order. Who heads NDMA? Prime Minister.

So we asked NDMA - who all were consulted before lockdown? Also, how many NDMA meetings did the PM attend? Their response.

NIL to both. Yes, NIL.

The first ever world map was sketched thousands of years ago by Indian saint
“Ramanujacharya” who simply translated the following verse from Mahabharat and gave the world its real face

In Mahabharat,it is described how 'Maharishi Ved Vyasa' gave away his divine vision to Sanjay


Dhritarashtra's charioteer so that he could describe him the events of the upcoming war.

But, even before questions of war could begin, Dhritarashtra asked him to describe how the world looks like from space.

This is how he described the face of the world:

सुदर्शनं प्रवक्ष्यामि द्वीपं तु कुरुनन्दन। परिमण्डलो महाराज द्वीपोऽसौ चक्रसंस्थितः॥
यथा हि पुरुषः पश्येदादर्शे मुखमात्मनः। एवं सुदर्शनद्वीपो दृश्यते चन्द्रमण्डले॥ द्विरंशे पिप्पलस्तत्र द्विरंशे च शशो महान्।

—वेद व्यास, भीष्म पर्व, महाभारत


Meaning:-

हे कुरुनन्दन ! सुदर्शन नामक यह द्वीप चक्र की भाँति गोलाकार स्थित है, जैसे पुरुष दर्पण में अपना मुख देखता है, उसी प्रकार यह द्वीप चन्द्रमण्डल में दिखायी देता है। इसके दो अंशो मे पीपल और दो अंशो मे विशाल शश (खरगोश) दिखायी देता है।


Meaning: "Just like a man sees his face in the mirror, so does the Earth appears in the Universe. In the first part you see leaves of the Peepal Tree, and in the next part you see a Rabbit."

Based on this shloka, Saint Ramanujacharya sketched out the map, but the world laughed

Time for a Thread🧵On yesterday’s “F&O Pe Charcha - Diary Of An Option Seller” with @Mitesh_Engr by @Paytm Money

Why Gain/loss ratio is important that the batting average
• More than the Win Loss ratio check the total Gain /loss ratio
• If your avg loss is 1% and avg gain is +5% then even if you are losing in 7 positions and winning in 3 out of 10 still you will be net profitable

Treat Trading as a business:
• Stick to a single strategy. Eg: A restaurateur usually wouldn’t be changing his recipe on a daily basis
• Mitesh Sir only works on BO or BD strategy, as he is a versatile trader

• Any trader should atleast experience 3 scenarios i.e. bull, bear & consolidation
• Target 4% per month i.e. 48% p.a.
• Option buying requires skill, everyday there wont be huge momentum, so buying options won’t yield good results, but high chances of falling into a bad habit

Stock Selection:
• In F&O segment there are ~150 stocks
• Not everyday all stocks will move
• Only 5-7 stocks move upside or downside
• Focus only these momentum stocks
• Check which one is moving
• Range BO/BD never disappoints. BO/BD from a rectangle (consolidation)

Gudimallam is a small village located in Chittoor district. It is seven miles away from Tirupati. This small village came to significance,due to it's very beautiful Shiva Mandir with history of thousands of years. 1/n


The main importance of the mandir lies in the Linga which is housed in the Garbhagriha of the temple & considered as the only one of such type. It is the earliest Linga discovered so far and it has been assigned to the 3rd century BCE.(Satavahana period) 2/n

Beautiful story of Shri Krishna, Mata Rukmini & Satyabhama which teaches the importance of Bhakthi.
Devotion is important than anything.
#bhakthi
🕉
Satyabhama, royal princess was very proud of herself. Rukmini was very humble, her devotion was pure to Shri Krishna.


One day, Rishi Narada( Kalahapriya) arrived in Dwaraka and met Sathyabhama. In between the conversation he hinted that Krishna exhibits affection more to Rukmini than her. Worried Sathyabhama asked what can should be done to gain Krishna's undivided attention.
@SriramKannan77


Narada asked Satyabhama to make a vow, that she will hand over Krishna to him as a slave, if she cannot trade wealth equivalent to Krishna's weight. Narada thus convinces Sathyabhama that Krishna will admire her for sacrificing all her wealth for him.


Sathyabhama was sure that she have enough wealth to balance Krishna.

She went to Krishna and told about her vow to Narada. Krishna patiently listened to her and accepted the challenge. Satyabhama arranged to bring large scales to weigh and brought all her precious jewels.


Krishna patiently sat on one plate of the Scales (tula). Sathyabhama started piling up the gold, jewels on the other plate. She kept adding more and more wealth, but the pan with Krishna did not even budge. Even after keeping all her jewels the scale did not move a little

Hey, for people interested in this stuff, here's a thread about a change we made to running our facebook account:

So, about 5 years ago, we got on facebook. Why? Well, facebook has a big audience and they like to consume on facebook. So, we started posting comics there, even though we got paid nothing and facebook made money off the free content.

Why? Because back then, once in a while, you would say "also hey, I sell books" or "hey, I'm going to be signing at this event" and your facebook followers would actually see it.

Effectively, the implicit old arrangement was "facebook lets me reach readers efficiently, and I supply facebook with free content they run ads on."

Over time, like a bad business partner, facebook basically made it impossible to reach your audience without *paying them*. Thus, you supply them free content on which they run ads, and you get nothing in exchange.
