Someone's little girl is singing and in the cool air her amplified voice is carrying kilometres across the valley into my precious ears.

Bless her, a braying donkey sounds better.

She's just started on Adele's "nothing but the best, for you" & she's slaughtering it so badly...

1. This is "Hollie The Card".

She's a Doctor, Physician, PhD, MA, Clinical Psychologist, Hospital Consultant, PTSD consultant, Long Covid Consultant.

2. Although sometimes she’s also an AUTHOR and English Academic.

3. A Hospital Consultant and ex Gymnast.

4. A Physician, Doctor, or hospital consultant.

A “Hospital Consultant”, would probably mean a senior doctor, in the UK at least.

5. Hollie changes her Twitter picture and bio so often, it’s hard to keep up with her qualifications.

Remembering Colonel Anil Kaul, VrC (Retd) on his 3rd Death Anniversary.

“It was October 12, 1987, exactly 5:55 pm as I was… coming out of the cupola of my T-72 tank on a steamy evening in an unknown place called Kokkuvil in the Jaffna district of Northern Sri Lanka.+

I froze in that confined space at what I saw. An LTTE militant stood at 60 meters aiming his rocket-propelled gun at my tank.

In a flash he fired. Probably having lost his nerve he aimed too low. The projectile hit the left mudguard of the tank, but for some inexplicable reason+

did not explode. It then hit the side of the main gun and then exploded on top of the turret, all in a fraction of a second. Before I knew, it seemed I had received a straight right punch so to say to my chin. I saw some blood appear on my left hand and there was a sharp drop in+

my eyesight.

Lt Colonel (now Lt Gen) Dalbir Singh, then Commanding Officer of 10 Para Commando, who was standing on the engine deck said to me, “Yaar what a close shave.”

He suddenly saw me and the look on his face told me that something was very very wrong with me. In that+

fraction of a second, as if it was a rewind of my entire life, thoughts raced through my life as to how and when I had landed myself in such a situation…

I asked my gunner to pull out a first field dressing (FFD) which is standard equipment in a first aid box carried in each+

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]

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.

1/ Here are my notes from @robertwrighter's book - Nonzero: the logic of human destiny. I enjoyed the book very much.

The basic premise of the book is that history has a direction which favors co-operation and non-zero sum games, and that causes an increase in complexity.

2/ Starting from the first replicating molecule which co-operated with an outer layer to form first proto-cell, evolutionary and cultural history is full of examples where two entities come together to survive and progress a lot more than they would have done individually.

3/ This co-operative entity fares much better than two individual entities because of specialization. If two entities are in the same boat - that they win together or lose together - then trust is implicit.

4/ In a non-zero sum game, trust causes entities to focus on what they do best.

For example, eukaryotic cells - the ones animals and plants have - emerged when two proto-cells merged, and one took the role of energy generator (mitochondria), the other specialized in protection.

5/ Some scientists believe that even nucleus in a cell is a result of an early cell merging with another cell.

So M&A is not a recent phenomena, entities have been merging because of common interests ever since life started.

🧵EMA + VWAP STRATEGY

Every trader has a go-to strategy that works best for them. My trading is all about keeping it simple stupid and revolves around two indicators - Exponential moving averages and vwap.

Here's the strategy that I utilize on nearly 80% of my trades.

👇

What are Exponential Moving Averages?

EMA's are a type of moving average that places a greater weight on more recent data points.

8EMA = Exponential Moving Averages of the last 8 candle closing prices.

EMA's adjust with respect to chart time frame.

What is VWAP?

Volume Weighted Average Price - A key intraday indicator in my trading that offers the true average price based on price & volume.

Calculation: (Price x # of shares traded) / total shares traded

EMA's I use

- 8
- 21
- 50

While I do utilize the 50EMA, the 8 & 21 EMA are most important for this strategy. Some people use the 9 and 20 which are essentially the same thing. REMEMBER: EMA'S adjust with respect to time frames.

A+ Set Up Criteria - (What I look for)
