Last up in Privacy Tech for #enigma2021, @xchatty speaking about "IMPLEMENTING DIFFERENTIAL PRIVACY FOR THE 2020
* 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
* required to collect it by the constitution
* but required to maintain privacy by law
* differential privacy is open and we can talk about privacy loss/accuracy tradeoff
* swapping assumed limitations of the attackers (e.g. limited computational power)
Change in the meaning of "privacy" as relative -- it requires a lot of explanation and overcoming organizational barriers.
* different groups at the Census thought that meant different things
* before, states were processed as they came in. Differential privacy requires everything be computed on at once
* required a lot more computing power
* initial implementation was by Dan Kiefer, who took a sabbatical
* expanded team to with Simson and others
* 2018 end to end test
* then got to move to AWS Elastic compute... but the monitoring wasn't good enough and had to create their own dashboard to track execution
* it wasn't a small amount of compute
* ... it wasn't well-received by the data users who thought there was too much error
If you avoid that, you might add bias to the data. How to avoid that? Let some data users get access to the measurement files [I don't follow]

Thought I'd put a thread together of some resources & people I consider really valuable & insightful for anyone considering or just starting out on their @SorareHQ journey. It's by no means comprehensive, this community is super helpful so no offence to anyone I've missed off...
1) Get yourself on the official Sorare Discord group https://t.co/1CWeyglJhu, the forum is always full of interesting debate. Got a question? Put it on the relevant thread & it's usually answered in minutes. This is also a great place to engage directly with the @SorareHQ team.
2) Bury your head in @HGLeitch's @SorareData & get to grips with all the collated information you have to hand FOR FREE! IMO it's vital for price-checking, scouting & S05 team building plus they are hosts to the forward thinking SO11 and SorareData Cups 🏆
3) Get on YouTube 📺, subscribe to @Qu_Tang_Clan's channel https://t.co/1ZxMsQR1kq & engross yourself in hours of Sorare tutorials & videos. There's a good crowd that log in to the live Gameweek shows where you get to see Quinny scratching his head/ beard over team selection.
4) Make sure to follow & give a listen to the @Sorare_Podcast on the streaming service of your choice 🔊, weekly shows are always insightful with great guests. Worth listening to the old episodes too as there's loads of information you'll take from them.

The 12 most important pieces of information and concepts I wish I knew about equity, as a software engineer.
A thread.
1. Equity is something Big Tech and high-growth companies award to software engineers at all levels. The more senior you are, the bigger the ratio can be:
2. Vesting, cliffs, refreshers, and sign-on clawbacks.
If you get awarded equity, you'll want to understand vesting and cliffs. A 1-year cliff is pretty common in most places that award equity.
Read more in this blog post I wrote: https://t.co/WxQ9pQh2mY
3. Stock options / ESOPs.
The most common form of equity compensation at early-stage startups that are high-growth.
And there are *so* many pitfalls you'll want to be aware of. You need to do your research on this: I can't do justice in a tweet.
https://t.co/cudLn3ngqi
4. RSUs (Restricted Stock Units)
A common form of equity compensation for publicly traded companies and Big Tech. One of the easier types of equity to understand: https://t.co/a5xU1H9IHP
5. Double-trigger RSUs. Typically RSUs for pre-IPO companies. I got these at Uber.
6. ESPP: a (typically) amazing employee perk at publicly traded companies. There's always risk, but this plan can typically offer good upsides.
7. Phantom shares. An interesting setup similar to RSUs... but you don't own stocks. Not frequent, but e.g. Adyen goes with this plan.

So it's now October 10, 2018 and....Rod Rosenstein is STILL not fired.
He's STILL in charge of the Mueller investigation.
He's STILL refusing to hand over the McCabe memos.
He's STILL holding up the declassification of the #SpyGate documents & their release to the public.
I love a good cover story.......
The guy had a face-to-face with El Grande Trumpo himself on Air Force One just 2 days ago. Inside just about the most secure SCIF in the world.
And Trump came out of AF1 and gave ol' Rod a big thumbs up!
And so we're right back to 'that dirty rat Rosenstein!' 2 days later.
At this point it's clear some members of Congress are either in on this and helping the cover story or they haven't got a clue and are out in the cold.
Note the conflicting stories about 'Rosenstein cancelled meeting with Congress on Oct 11!"
First, rumors surfaced of a scheduled meeting on Oct. 11 between Rosenstein & members of Congress, and Rosenstein just cancelled it.

Rep. Andy Biggs and Rep. Matt Gaetz say DAG Rod Rosenstein cancelled an Oct. 11 appearance before the judiciary and oversight committees. They are now calling for a subpoena. pic.twitter.com/TknVHKjXtd

#ஆதித்தியஹ்ருதயம் ஸ்தோத்திரம்
இது சூரிய குலத்தில் உதித்த இராமபிரானுக்கு தமிழ் முனிவர் அகத்தியர் உபதேசித்ததாக வால்மீகி இராமாயணத்தில் வருகிறது. ஆதித்ய ஹ்ருதயத்தைத் தினமும் ஓதினால் பெரும் பயன் பெறலாம் என மகான்களும் ஞானிகளும் காலம் காலமாகக் கூறி வருகின்றனர். ராம-ராவண யுத்தத்தை
தேவர்களுடன் சேர்ந்து பார்க்க வந்திருந்த அகத்தியர், அப்போது போரினால் களைத்து, கவலையுடன் காணப்பட்ட ராமபிரானை அணுகி, மனிதர்களிலேயே சிறந்தவனான ராமா போரில் எந்த மந்திரத்தைப் பாராயணம் செய்தால் எல்லா பகைவர்களையும் வெல்ல முடியுமோ அந்த ரகசிய மந்திரத்தை, வேதத்தில் சொல்லப்பட்டுள்ளதை உனக்கு
நான் உபதேசிக்கிறேன், கேள் என்று கூறி உபதேசித்தார். முதல் இரு சுலோகங்கள் சூழ்நிலையை விவரிக்கின்றன. மூன்றாவது சுலோகம் அகத்தியர் இராமபிரானை விளித்துக் கூறுவதாக அமைந்திருக்கிறது. நான்காவது சுலோகம் முதல் முப்பதாம் சுலோகம் வரை ஆதித்ய ஹ்ருதயம் என்னும் நூல். முப்பத்தி ஒன்றாம் சுலோகம்
இந்தத் துதியால் மகிழ்ந்த சூரியன் இராமனை வாழ்த்துவதைக் கூறுவதாக அமைந்திருக்கிறது.
ஐந்தாவது ஸ்லோகம்:
ஸர்வ மங்கள் மாங்கல்யம் ஸர்வ பாப ப்ரநாசனம்
சிந்தா சோக ப்ரசமனம் ஆயுர் வர்த்தனம் உத்தமம்
பொருள்: இந்த அதித்ய ஹ்ருதயம் என்ற துதி மங்களங்களில் சிறந்தது, பாவங்களையும் கவலைகளையும்
குழப்பங்களையும் நீக்குவது, வாழ்நாளை நீட்டிப்பது, மிகவும் சிறந்தது. இதயத்தில் வசிக்கும் பகவானுடைய அனுக்ரகத்தை அளிப்பதாகும்.
முழு ஸ்லோக லிங்க் பொருளுடன் இங்கே உள்ளது https://t.co/Q3qm1TfPmk
சூரியன் உலக இயக்கத்திற்கு மிக முக்கியமானவர். சூரிய சக்தியால்தான் ஜீவராசிகள், பயிர்கள்
