2020 was a game changer for Ethereum.

The vast majority of its success was fueled by #DeFi.

Here's what happened in 5 Tweets 🔽

🎉🎉 PHP 7.3 is here!

Here are the things I'm excited about.

🚂 Trailing commas in function/method calls!

This will certainly be a required styling choice for me. Same delightful benefits of trailing comma in multi-line PHP arrays, and JavaScript objects.

🧵 Less disgusting heredoc syntax!

Inlining heredoc strings in any way right now is grrrosssss. Now we get sensible capabilities. Everything that was wrong with it is now fixed!

(Ignore the bad syntax highlighting)

☠️ Finally, not-so-silent json_decode error detection!

This really sucked before, now it just sucks a bit less (who wants to pass a 4th param and pass 2 default params first? (helper function anybody?)

📜 Not horrible functions for getting the first and last item (or key) from an array!

Before you either strung a bunch of functions together or messed with internal array pointers. This is a much-needed improvement.

The best way to know if people like your product is NOT:

- Have a lot of emails in the waiting list
- Become #1 on PH
- Become #1 of HN or Reddit
- Have people that saing "I'll pay"
- Have a lot of free users

The best way to know if they're actually pay for it.

The only thing that matters is your product providing a value, and you can't know this until people will pay money for it.

We can have a first signal of a product/market fit after the launch by check how many sales we've got in the first 24h. Some scale:

200+ This has a high potential.
100+: This has a potential.
50+: Some people need it.
10+: People almost don't need it.
0+: People don't need it.

This is for a single time payment product. For a subscription probably it should be less because people hate subscription.

And obviously, you should have a lot of traffic like 3-5k+.

Here is a stat for my products (macOS apps) for the first 24h after the launch:

SRI MOOKAMBIKA DEVI, KOLLUR (KAR)

There was an Asura, Kaumasura, who was doing penance to please Shiva and get a boon. To prevent him from asking for a boon, Devi Saraswati made him dumb (hence called Mookasur)
Later, Adi Parashakti slayed him and came to be called Mookambika.

It is said that Adi Shankaracharya had a vision in which Devi agreed to follow him provided he did not look back. He kept walking and was assured of her presence due to the sound of anklets. When he reached here in Kollur, he turned back as the sound of anklets had stopped.

So Devi stayed here and merged with the lingam. The place came to be called Mookambika Kshetram.
The linga has integrated on it’s left side MahaKali, Maha Lakshmi and Maha Saraswathi and on the right side- Brahma, Vishnu and Shiva.

A swarna rekha (gold line) divides this linga into left and right portion. Adi Shakthi in this Udhbhavlinga form appears only here.
Devi sits in padmasana and has 4 hands.
Adi Shankaracharya installed the Sri Chakra in front of Devi and also composed the Soundarya Lahiri here.

The Ife Primary Education Research Project (1970-1983).

aka

The Ife 6-Year Primary Project.

In 1970, as the Director of the Institute of Education of the then University of Ife (now Obafemi Awolowo University, Ile-Ife), later Dean Faculty of Education, Prof. Babs Fafunwa & his team embarked on one of the most groundbreaking research projects in education for Yorubaland.

The aim of the project was to test the hypothesis that the best instructional medium for good concept formation at a very tender age is the mother tongue.

This was bolstered by the observation that “of all the continents and peoples of the world, it is only in Africa…

…that formal education is offered in a language that is foreign to the child.”

So, Yoruba was to be used & tested as an exclusive medium of passing information or instructions to a set of pupils.

The project was based on the premise that:

(a). the child will benefit culturally, socially, linguistically & cognitively.

(b). the child’s command of English will be improved if he is taught English as an entirely separate subject by a specialist teacher through the 6 years.
