## past vindicative specializations

Quant and other Unsuccessful diversifications are not the primary focus today, but they are listed below the table.

see also — For the “domains nlg” (first 3 rows), marketable_domain_xp spreadsheet is more comprehensive but not necessarily more updated.

 (scales 0-5)  ⇘ mkt value given my direction robust
entry barrier accu achieved %%expertise among peers i was surprised wage ROI
mktData #socket  4 growing not everyone has xp  2~3  2  4 none
bondMath  3 robust math is not natural
to most dev
 2  3~4  3 none
orderBook, OMS, FIX #Eq/FX  3-4 robust medium 1 #cod`IV 1  3 none
c++  5 ok not
higher than I thought  5  3  2 minimal
Algo practice  5 Growing high 4 #XR disagrees  5  5 none
python  4~3 growing low  2  3 #unknown  3 none
bash scripting + commands  2 robust medium  4  4  5~3 none

(abstract?) container internals 5 unexpected strength medium  5  5 4 none
RDBMS 3~4 shrinking low  5  4 5 #under-whelming none
MOM 2 robust medium  1  1 4 none

–algo practice for IV
^ good amount of accumulation
^ my confidence is boosted esp. in c++
^ I’m rising to the challenge of coding test growing popular

^ boosts my IV confidence
▼no critical mass yet
▼low traction
▼don’t know my expertise relative to peers

–option domain knowledge including BS:
▼ much lower demand than bond math

— C# and XAML
^ Microsoft is a major force
▼not aligned to my current direction

^ was my Achilles heel, now slowly gaining confidence

–C++ GTD and IV
^ I made real progress in 1) GTD and 2) IV but not during Mac days — wrong job nature
^ deepens my java understanding
▼ those high paying domains (HFT, quant) are too hard to break into

–MOM architecture, products…
▼ not as widespread as I perceived

–javascript, php, mysql
▼not aligned to my direction

▼ market too fragmented

–EJB, Spring, Hibernate
▼falling out of favor
