The #worldwildlifeday2021 theme is Forests and Livelihoods: Sustaining People and Planet aligning with UN Sustainable Development Goals 1, 12, 13 and 15. So, what are the UN Sustainable Development Goals (SDGs) & how can children begin to learn about them & get involved ?

 https://t.co/8ICvHxE9QL is easy & fun to follow for our smallest of people #EYFS. Early childhood is the perfect stage to introduce the core concepts of what it means to be a global citizen. For our reception & KS1 children please take a look at this fabulous free resource
https://t.co/tZx8UIS58Q Storytelling is a powerful communications tool and helps children remember lessons and virtues that they will use in everyday life. The idea is to simplify the lessons of the (SDGs) so young children can relate to – and better understand – the SDGs.
For older children here’s a board game that aims to help teach children around the world about the Sustainable Development Goals in a simple and child-friendly way https://t.co/ijhyd068LQ
This is a lovely free book for children to enjoy flicking through themselves https://t.co/ScMbQCfpjl Elyx, the United Nations’ digital ambassador, uses various expressions and actions to help demonstrate the meaning of each Sustainable Development Goal.
KS2 children can become a Climate Action Superhero https://t.co/S6nQmMLsHE Each of their missions has downloadable content including activities for kids to do with the help of an adult. We also have a fun quiz for you to see how much you know about sustainability!
I hope I have signposted you to some fabulous free & fun resources that you might choose to take a look at over half term. We will be learning more about the SDGs in Outdoor Learning sessions & considering what we can do to & how we can positively impact the change on our planet.

@cain_nate My friend Nate Cain and I have worked hundreds of hours with various politicians and legal groups trying to explain the election laws and how they fit together. There are many misperceptions of what happened during this election and what it means.

Simply put, our election laws are an intricate tapestry designed to ensure accuracy and prevent fraud. They work together like parts of a car. But when certain parts fail, the car is just a hunk of scrap iron and plastic. In this case critical parts failed.
2/

You do not have to prove fraud or intent, you just have to show that the election officials were unable to conduct an election that met the law and relevant certification requirements. In this case, the election does not come close to meeting accuracy requirements.
3/

These specifications are found deep in laws like FISMA, HAVA, and state adoptions of EAC guidance. 1 ballot error out of 125,000 or 1 position read error out of 500,000. Just look at the discrepancies between incoming ballot counts and total votes, the system fails.
4/

It is worse in the the swing states in Democrat strongholds but it is bad in many places. You add the apparent losses of ballots through the Mail and error rates in the ‘system’ are staggering. Why do we have these rules? Sure it is to prevent fraud, but......

So, here's my contrarian take on Why Trunk-Based Development Is Great But Probably Won't Work For You. Buckle up, it's a long one.

From time to time I talk about, or boost someone else's discussion of, "classical" continuous integration/trunk-based development/push-to-master/whatever. I do this because I've personally worked like this and I genuinely think it's a marvelous way to write software.

I've also, at this point in my career, failed—a bunch of times!—to bring this technique into practical use on the teams and organizations I've worked with. As a result, while I still do it myself, I don't focus as much on encouraging it in others.

The technoculture that's presently in vogue is what I think of as async/individual—optimize for the individual, performance-manage the individual, decouple the individual from others so they can be their best, most productive, most heroic selves.

This is in contrast to what I think of as sync/team—a culture that leans into interdependence and collaboration. If you've never worked on a team that collaborates very closely every day for months or years on end (and likes it) you've likely not experienced a team like this.

(PART 3) Angels - Izingelosi | Izithunywa of the 1st Sphere 🕯

[A Smallanyana Thread]

On Part 1 and 2, you will notice that we covered Angels that somehow also resemble human physical/ manifested features.

Part of the classic examples of how we as humans always depict these Celestial Beings through our works of art.

As we move up to the 1st Sphere of the Christian Angelology Hierarchy we get introduced to another breed of Izithunywa.

Let's Begin 📖

THRONES:

Also known as the Elders, they are a class of Celestial Beings mentioned by Paul the Apostle in Colossians 1:16, and they are also mentioned in the Book of Revelations as the 24 Elders.

They are the living symbols of God's justice and authority, symbolised as Thrones.

They are also associated with the Ophanim from the Jewish Angelic Hierarchy (Which we will still cover in detail within this series of Threads).

The Ophanim are referenced as Wheels seen in Ezekiel's vision of the Chariot in Ezekiel 1:15 - 21.

Also refer to Elijah's ascension.

THREAD: On the full-fledged process of responding to a Revise-And-Resubmit (R&R).

I have written pieces of the process, but I hadn't actually written a thread or a blog post showcasing how all my blog posts fit with one another. I teach this process when I give workshops.

So here's what I do (now), and let me share a lesson from my past lives:

DO NOT SIT ON R&Rs.

I know, they're painful and scary and sometimes we don't know if our paper will get rejected in the end.

But remember, an R&R means an OPPORTUNITY to get your paper published.

Sitting on R&Rs, leaving them for later, and not prioritizing them has gotten me fewer publications. I know this for a fact. I am not ashamed of admitting that I have sometimes felt that I will not be capable of responding to multiple (often conflicting) comments.

HOWEVER...

Sustained, frequent advice from professors who are senior to me (though I am senior myself now too) is always the same and on-point:

The goal is the R&R.

You're not getting a desk rejection.

You are getting your work read, reviewed carefully, thought about, responded to.

What do I do now (and have been doing for the past few years, with success)

When I get the R&R (the "decision letter"), I make sure to calm down, because I am always afraid I'm going to get nasty comments. These have been (luckily) very rarely present in my latest submissions.

🕵️‍♂️ How Google's PageRank algorithm works

The PageRank algorithm gives each page a rating of its
importance, which is a recursively defined measure of importance, based on if important pages link to it.
It's recursive because the importance of a page refers back to the importance of other pages that link to it

Here's how it works in practice:
1⃣ We start with some pages and crawl them for links


2⃣ Each page has 1/N points (where N as the total number of pages)


3⃣ Add points to each page for the amount of links to it, divided by the number
of links emanating from the sources of these links

1/ Some initial thoughts on personal moats:

Like company moats, your personal moat should be a competitive advantage that is not only durable—it should also compound over time.

4/ Before the arrival of recorded music, what used to be scarce was the actual music itself — required an in-person artist.

After recorded music, the music itself became abundant and what became scarce was curation, distribution, and self space.

5/ Similarly, in careers, what used to be (more) scarce were things like ideas, money, and exclusive relationships.

In the internet economy, what has become scarce are things like specific knowledge, rare & valuable skills, and great reputations.

Krishna & Paarijaata apaharana #sculpture #story #Thread

Parijata tree was in Indraloka which was one of gifts he received from churning of Ocean to obtain Amrit.

This beautiful #sculpture depicts Indra Dev chasing Shri Krishna for stealing parijatha tree branch from Indralok


📸- sculpture on outer walls of Hoysaleswara temple, Halebeedu,Karnataka

Krishna has 4hands with Shankha,Chakra,Mace&Lotus holding Satyabhama tightly,mounted on Garuda. Garuda has a beautifully carved Parijata tree trunk in left hand& a weapon in his right hand, attacking Indra.

Other side is Indra,riding on Airavata.Indra can be seen attacking Krishna with his Vajrayutham.Airavata is charging towards Garuda.Wife of Indra can be seen in pillion seat.Just look at the Detailing of Garuda & Airavat sculptures.

So what led Krishna to steal parijatha tree👇

Narada Rishi once returning from Indralok collected few Parijatha flowers&reached Dwaraka.There he met Bhagwan Krishna&gave the heavenly flowers to him.Narada explained the greatness of Parijatha flowers & also said that these flowers must be given to the most loved ones.


Despite knowing Satyabhama’s anger,Krishna gave it to Rukmani Devi.Narada Rishi then went to palace of Satyabhama. He narrated whole incident that had happened.Satyabhama turned furious on hearing that Krishna gave Parijatha to Rukmini.Then Satyabhama shows her anger to Krishna.

First thread of the year because I have time during MCO. As requested, a thread on the gods and spirits of Malay folk religion. Some are indigenous, some are of Indian origin, some have Islamic


Before I begin, it might be worth explaining the Malay conception of the spirit world. At its deepest level, Malay religious belief is animist. All living beings and even certain objects are said to have a soul. Natural phenomena are either controlled by or personified as spirits

Although these beings had to be respected, not all of them were powerful enough to be considered gods. Offerings would be made to the spirits that had greater influence on human life. Spells and incantations would invoke their


Two known examples of such elemental spirits that had god-like status are Raja Angin (king of the wind) and Mambang Tali Arus (spirit of river currents). There were undoubtedly many more which have been lost to time

Contact with ancient India brought the influence of Hinduism and Buddhism to SEA. What we now call Hinduism similarly developed in India out of native animism and the more formal Vedic tradition. This can be seen in the multitude of sacred animals and location-specific Hindu gods

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

https://t.co/7QIx5CFdfJ


The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.
