If you're interested in DB internals, stop what you're doing and watch @CMUDB Quarantine Talk from Nico+Cesar about @SQLServer's Cascades query optimizer: https://t.co/FCdsbHHEaD

Many talks this semester were good. This one is the best. My thread provides key takeaways

So there's a class of puzzles called "river crossing puzzles" which involve having to cross a river on a boat/bridge containing some set of individuals/items with restrictions on which ones can be on the boat/left on each shore, right?

and the most common subclass of these problems is the one where you have 3 items/animals to cross with.
This is alternatively called the "fox, goose, and bag of beans" or "wolf, goat, and cabbage" puzzle.

the idea is that your boat can only carry one item at a time, but if you leave the wolf/fox unattended with the goat/goose, the wolf/fox will eat the goat/goose.
and similarly, the goose/goat will eat the beans/cabbage if left alone

so you have to set up a set of actions that never leaves either side of the river in one of the lose-states.

the solution to this variant being:
1. take the goat/goose over
2. return empty
3. take the wolf/fox over
4. return with the goat/goose
5. take the cabbage/beans over
6. return empty
7. take the goat/goose over

1/ So here is a thread on how I turned $32,000 into $1.2m and back to pretty much zero (once taxes are paid).

Just note, I am not bitter or salty in any way at all, the last 2 years have been an amazing ride - travelled the world, been wealthy, been poor.

2/ Dec '16, my advertising agency folded, I had a little bit of money left and I put $32k into Bitcoin and Ether. As it started to go up I diversified into everything, Monero, Dash, this that, any crap - even Ripplecoin. Everything just kept going up.

3/ By March I think I had around $300k and $500k by the summer. I used to take 25% out but towards the end of the summer I got greedy and put it all back in and by December it was $1.2m.

4/ Thinking I was an absolute genius I decided to start a bunch of businesses. As silly as it sounds I had this goal of making $5m as I wanted to buy Bedford Town Football Club and get them in the league, and as Crypto was going up forever I needed 6 months.

5/ So:
- Trading (income 1)
- Podcast (income 2)
- Mining (income 3)
- Mining pool (income 4)
- Consulting (income 5)

Yes - all of the above as a one-man army :)

1/OK, I should really write another thread about university-centric regional development, because I think people often make some (very understandable) mistakes when thinking about this issue.

2/The biggest myth, I think, is that universities help regions by educating locals as undergraduates.

Skeptics of universities say: "But most of the people who graduate end up leaving."

3/In fact, most of what a university does for a regional economy is NOT about educating local kids.

Educating local kids is good for the nation, but doesn't help a region much.

The way a university helps a region is through

4/Undergraduates usually leave town after graduation.

But university RESEARCH pulls in OTHER smart people from other regions, and they stay there.

Here's a paper showing that this is the main way universities increase a region's human capital:

5/Research also pulls in business investment.

Companies want to partner with university labs, so they can commercialize the technologies the labs produce. So they invest in the labs, and sometimes they even put their offices in the town.

Secrets of Ganapati (Author - Keshav Sitaram Thackeray)

This article is taken from Keshav Sitaram Thackeray's book 'Dharmachi Devale and Devalcha Dharma'. In it, Bal Thackeray's father is claiming how the Hindu deity of Ganesha is imaginary.

Buddha is Ashtavinayak and "Ganapati Bappa Morya" is "Chandragupta Morya".

In the era of democracy, the head of state is the President. But in ancient India, there was a Gana culture in the monarchy and the head of that Gana was called Ganapati
(2/20)

In ancient India, a prince named Siddharth Gautam was born in royalty. He later became the king of Shakya Gana in this Gana culture. In time, Siddhartha attained enlightenment.

Let us now understand the difference between a real Ganapati and an imaginary Ganapati.

Some clever Brahmin manuvadis made the real Ganapati the imaginary Ganapati.

Buddha was the king of the Shakya Gana, so people called him Ganaraja. He founded Buddhism and became the head of the Shakyas. As the head of Gana, people used to call Buddha as Ganapati.
(4/20)

But the Brahmins Brahmanized Ganapati and created a false Ganapati. When Buddha used to give the message of Dharma to the people, two words would come out of his message. Chitta and Malla.

Chitta is the body.
Malla means waste

Ｇａｕ Ｍａｔａ Ｉｎ Ｖｅｄｉｃ
Ｃｕｌｔｕｒｅ

It is said that the one who bears the dust thrown from the hoof of Gaumata on his head, as if taking a bath in the water of the teerth sthalam and getting rid of all sins.

Ved and all other Hindu scriptures venerate the cow. The Vedic dictionary, Nighantu, gives amongst other synonyms of 'Gau' [ or cow] the words 'Aghnya', 'Ahi', and 'Aditi'.

Yaska the vedic decoder and commentator on Nighantu, defines these as-

Aghnya —— the one that ought not to be killed
Ahi —— the one that must not be slaughtered.
Aditi —— the one that ought not to be cut into pieces.

These three names of cow signify that this is an animal which should not to be put to tortures. These words appear frequently throughout the Veda in context of the cow.

But in due course the falsehood of killing cows spread far and wide and they became even more deep rooted when western scholars with their half baked knowledge of Sanskrit transliterated these interpretations of commentaries of Sayanacharya ,
