Math solution to 2^x = 9

A solution to the math problem: 2^x = 9

Take the log of both sides. You get:

• x * log 2 = log 9

Divide by log 2 to solve for x. You get:

• x = 3.17

Substitute for x to prove your solution:

• 2 ^ 3.17 = 9

Q.E.D. 

Rust pop-quiz answer: querying Terra swagger endpoint

Rust pop-quiz answer: query @terra_money swagger endpoint for all_balances.

This is a simple swagger-call at base, ... which I embellished (converting obvious numbers from strings), then embellished again (converting denom to token ... by hand).  

ℕ𝕆𝕋𝔼! The @terra_money swagger result for all_balances leaves out a 𝓼𝓲𝓰𝓷𝓲𝓯𝓲𝓬𝓪𝓷𝓽 number and types of tokens in my wallet, ...

... perhaps this lack is due to the many new and revised tokens introduced after the swagger endpoint was established (and abandoned?)

Token performance, post-Pilot launch: cryptocurrency pop-quiz answer

#cryptocurrency pop-quiz answer for token-valuation behavior after a Kujira Pilot launch:

1. $WINK* was the 10-bag gainer, here. The other three { $AQLA, $BFIT, $NAMI } where 10x LOSERS by token-price since launch.

* did anybody see the total number of $WINK tokens? 69M. 

So: are they $WINK-ers or $WANK-ers? Eh? EH? 😎

2. ROIs and APRs are shown as above.
3. Projected valuation across token launches on @TeamKujira Pilot

Based upon the previous lauches, a token's launch has this behavior following a launch on Pilot:

ROI: -79.75%; -508.90% APR

Every token, except $WINK, follows this trend. Will $KART?

Kujira Pilot launch of KART by premium: pop-quiz answer

#Cryptocurrency pop-quiz answer:

$KART launch on @TeamKujira Pilot happened in a flash.

• 45M $KART sold at launch
• ~ 492,570.00 $USK raised

Congratulations and «bon chance!» to all who participated.

Rust pop-quiz answer: Configuring reading configuration files by git branches

#Rust pop-quiz answer to configuring reading configuration files by git branches.

code 

I've inlined a branch-parameter into reading REST resources. This came about whilst doing work on pivot-trading. 

Cryptocurrency pop-quiz answer: "What's my $ETH position?" as a Voronoi chart

For the #cryptocurrency pop-quiz on "What's my $ETH position?" I went with option 3, creating a cypher query against my @neo4j Blockaverse portfolio ontology.

This approach allows me to map out my positions and their relative strengths in, say, a Voronoi chart. 

Cryptocurrency pop-quiz answer: liquidity by domain

#cryptocurrency pop-quiz answer

Rust is not necessary, as a simple @neo4j cypher load-script overlays domains onto protocols

dom.cyph sources.

We can now query liquidity by domain to see to what end the liquidity is deployed. 

Rust pop-quiz answer: portfolio-as-ontology in neo4j

#Rust pop-quiz answer to the quiz of: portfolio-as-ontology.

Behold! ./ont.

Also, I have a video walkthrough of creating, viewing, and querying the ontology in @neo4j. 

Rust pop-quiz answer: one_line

#Rust pop-quiz answer to the question of concatenating multiline input to one line: one_line is now a new app I use to generate my reports, particularly the Sumo vault report.

Coding is simple when one can rely on preexisting library functions, innit? 😎

Rust pop-quiz answer: Venn Diagram of Kujira FIN 24h-volumes

#Rust pop-quiz of Venn diagramming the 24h-volumes on Kujira FIN: ANSWERED!

./top_traded

for your coding-pleasure.

Rust pop-quiz answer: totally rows of data in reports

#Rust pop-quiz answer to totaling rows of data in reports:

That took more effort than I care to admit, as reportage and formatting always do. 🙄

BUT! Now we have reports with a totals-row, and I am well-pleased, even if I had to invent matrices to get there.

./tabla.

Rust pop-quiz answer: tabla

In answer to the Rust pop-quiz about HTML-formatting data tables, ...

Behold! ./tabla.

Most of the work to effect this was done in the html_utils book lib where you see the BONUS section (right justify numbers) is handled there, as well. 

Rust pop-quiz answer: accurate Kujira FIN order book volumes

Okay, there was a part-I of the #Rust pop-quiz answer: accurate token prices.

Now we carry part I to part II by rewriting the Book-type to record each token's 24h-USD-volume. 

Rust pop-quiz answer: accurate pricing of actively-traded tokens on Kujira FIN

#Rust pop-quiz answer to rewriting token-price-calculation.

A complete rewrite has now 60+ tokens accurately priced from active trades in @TeamKujira FIN.

https://github.com/logicalgraphs/crypto-n-rust/blob/main/src/libs/crypto/types/books.rs#L147-L237

This solution uses HashMap chaining and higher-order fuctional composition to avoid unnecessary collection-mutation. 

The above is part I to get to the solution.

Next comes part II: accurate order book volumes.

Rust pop-quiz answer: simplifying parsing lines code

#Rust pop-quiz answer to simply parsing lines of data.

THIS is more like it!

That is: after writing a generic parse_lines()-fn in string_utils. 

Allowing me to write a parse_data()-fn in file_utils, simply. 

For context, the three functions, COMBINED, with two new functionalities are less lines of code than the original line-parser-fn.

Rust pop-quiz answer: limit to relevant Kujira FIN order books

#Rust pop-quiz answer for limiting which Kujira FIN order books are shown.

With a simple retain(), I limit @TeamKujira FIN order books to the ones I find relevant (by 24h-volume). 

Rust pop-quiz answer: colors, HashMaps, and macros, oh, my!

#Rust answer to color-management pop-quiz.

I externalized color-management.

Then, with a HashMap, a compose-macro, and some simple string-parsing functions, we have color management! YUS! 🎉

Rust pop-quiz answer: analyses of PnL trades by day

#Rust pop-quiz answer to the question of analyzing PnL of trades by day.

To do the analyses above, I needed a trades-by-day HashMap. 

Once I had that, the answers fell out from the most- or least- value in that map.

Rust pop-quiz answer: sorting assets by pnl

#Rust pop-quiz answer to the pop-quiz about sorting assets by pnl.

Sorting assets by pnl becomes easy, once that code it broken out into its own reports-module.

Rust pop-quiz answer: Top 5s, ... or not

Rust pop-answer

I had a pop-quiz to change "Top 5" to "Top [n]" if the Top-5 ... weren't.

Here's the answer: 

And you see the result of that re-coding in yesterday's ORCA report.
