(1/x) Sheesh, ngl it’s been a hot second since we’ve gotten to work on PXN. Now that we minted out, think it’s time for a little story about my own journey in both Nano and PXN. Buckle up, this is gonna be a long 🧵
(2/x) To start off, for those of y’all that don’t know, I started off in @nanoverseHQ back in late October, but didn’t start popping off till Early November when I came back home from a family vacation.
@nanoverseHQ (3/x) Due to the jetlag, I was out here crashing at 7 pm and waking up at 3-4 am, so what did I do? Hop on Discord ofc and chat it up with da boiz. I still remember those late nights at demon hrs with @GT3NFT and recounting some fun stories with @veezyvangogh and @Yuri_ramen.

#SQL from #R is insane. Here’s why. 1/6

Image Credit: @yutannihilat_en

#rstats
2/6 Thanks to Hiroaki Yutani for putting this amazing example together.

This small example demonstrates how you can learn R and automatically use SQL.
3/6 Under the hood, the dbplyr library converts R’s tidyverse syntax to SQL

So we don’t need to memorize the SQL translation.

Do choirs have accents?
Now I am 3 years into the PhD I have some thoughts I would like to share with you…
Here’s a wee thread🧵#AcademicChatter #AcademicTwitter #SingingResearch #SpheresOfSinging
1\
Why?
Over 2 million people sing in choirs every week in the UK.
Everyone has an accent - and accents can differ by many different social factors (incl. region, age, gender, education and more).
\2
Choir directors anecdotally report differences in choir sound by region. And, in musicology, Classical singing technique™ and choral singing has been associated with Received Pronunciation AKA “the Queen’s English”.

I've been using #R and @rstudio for years to tackle all kinds of data and coding problems. Here are some of my favorite shortcut keys to improve productivity and make your life easier. (1/7)
Insert pipe - The pipe operator is everywhere in modern R code but typing it can be tedious. Use 𝗖𝘁𝗿𝗹 + 𝗦𝗵𝗶𝗳𝘁 + 𝗠 to build your pipes quicker. (2/7)
Comment/uncomment blocks - Sometimes you want to quickly disable a chunk of code without deleting it. Use 𝗖𝘁𝗿𝗹 + 𝗦𝗵𝗶𝗳𝘁 + 𝗖 to (un)comment entire code blocks. (3/7)

My biggest mistakes were never my insights. They were in over-confidence.

An #rstats + #bayesian 🧵
2/n In business, I've made great regression models that have predicted how much sales we were going to make.

In fact, this helped me increase revenue from $3M to $15,000,000 per year at one of the companies I worked at.

BUT my models were NOT perfect.
3/n In fact, I'd argue that the BIGGEST flops were due to over-confidence.

Believing my model was better than it actually was.

Here's what hurt me...

@WifeyAlpha recently posted a thread with 16 buy-and-hold asset allocation schemes, i.e. fixed-weight portfolios that can be implemented with ETFs. I decided to write some code to test these in #R #RStats. The code is available on #RPubs:
rpubs.com/arubesam/stati…
The code is a quick & dirty calculation using monthly returns with monthly rebal. It does not take into account transaction costs. The code can be easily adapted to test other asset allocation schemes.
I use the following #R packages: quantmod to get prices from Yahoo; PerformanceAnalytics for calculation of performance metrics. All backtests start when data for all necessary tickers becomes available.

Many young people ask me how they can become a #DataScientist, specifically in #football. Lately I have also seen a lot of posts on how to get into #DataScience in (1)50 days or so, which is a joke imo. Here is my realistic take on it. Warning: it will be closer to 1500 days. 🧵
#DataScience is an umbrella of roles & fields that require different competencies. But they all have two things in common: you have to know #Science and you have to be able to work with #data. The first requires learning to do research, the second learning to do #programming.
Go to uni and get a masters degree that at least requires some #math skills. I’m not saying you need a #PhD and 5 publications before calling yourself a #DataScientist, nor that you can’t be one without a MSc, but is helps a lot in acquiring the right competencies.

Good Morning everyone!

Remember those whole GINORMOUS cities that have not 1 person living within them?

These “Abandon” (by design) Cities were built up for A reason, they’ve been built up for A VERY VERY long time …
All purposely built up to make the world/masses think
Something Real is happening when in reality it’s two “sides” trying to PUSH the Worlds population into whatever direction [They] #NEED the worlds population to go, A direction that benefits ONLY [Them] …

How many past wars were done this exact way?
How many past wars were
Staged, Pre planned & done specifically as Blood Ritual Sacrifices to [Their] false gods?

Do you think the world can handle the whole truth?

All I have mentioned above, it’s A larger % of truth but is still on the lower end % of all the horrific things that have been done

People are shocked when they learn that I picked #R over Python. It’s a true story.

I began learning data science with Python. This decision actually cost me 2-months and caused me to quit data science for a little bit.

Why? (a 🧵)
#rstats Image
2/n Python was too much like coding. And I came from a business background. My main tool was Excel. Python was unnatural.

A friend of mine recommended me to try #R.

I was instantly surprised at how much more intuitive it was for me given my Excel background. Here's what R had:
3/n
👉#R has functions just like #Excel. I could quickly summarize my data using mean(), sd(), sum(), and friends. These functions were very similar to AVERAGE(), STDEV(), and SUM() from Excel.

After listening to drumbeat of #War I was decided to share my vision on ongoing crisis of #Ukraine
Long thread
#Russia #Ukraine #WW3 #history Image
First that western audience is missing - that's a truth why #Ukraine? Russia was not invading in Ukraine in #2014 and do not annex a #Crimea

People of Crimea decided on the referendum to walk away from Ukraine and join #Russia on 16 of March 2014 Image
To understand why people of #Crimea and after them people of #Donbas and leave behind #Ukraine where is #coup happened
We filmed a very tough documentary on that topic, if you didn't see that - there is a free copy from us

(1)In dieser Grafik kann man gut erkennen, dass sich #Omikron unter den gleichen Umgebungs- und Immunitätsbedingungen in 🏴󠁧󠁢󠁥󠁮󠁧󠁿 mit einem 7x höherem #R-Wert ausbreitet.
(2) Dies bedeutet, dass Delta von einer Person auf eine weitere übertragen wird, während Omikron auf 7 weitere übertragen wird.

Man kann sagen, dass 🏴󠁧󠁢󠁥󠁮󠁧󠁿Delta recht gut im Griff hatte, jetzt kommt Omikron daher und stellt das marodierte NHS vor eine komplett neue Herausforderung
(3)In Flagge von Deutschland bremsen wir #Omikron durch die bestehenden Restriktionen um etwa ein Drittel (im Vergleich zu UK) aus. Da wir etwas später dran sind, haben wir auch mehr Zeit für die Entfaltung der Booster-Immunität.

🧵Ho letto con interesse il Suo articolo e mi colpiscono due passaggi.
1. L'affermazione che il #PatentBox (#PB) stia funzionando motivata dall'importo crescente e dal num. crescente dei beneficiari dell'agevolazione.
2. L'affermazione che l'agevolaz. abbia premiato i "migliori"
i.e. le aziende più "performanti" (migliori margini rispetto allo sfruttamento degli intangibili).
Poco più di un anno fa la #CortedeiConti ha (più che giustamente dal mio punto di vista) evidenziato 👇 come sia riduttivo misurare l'efficacia della misura basandosi meramente Image
sulle quantificazioni di cui al punto 1 ma sia invece necessario a) indagare su come l'agevolazione si sia distribuita tra diversi attori economici e b) analizzarne gli effetti in termini di crescita del numero di brevetti e addizionalità. Se quest'analisi, basata su micro-dati,
