MERN

  • mongo
  • express
  • react
  • node
  • database
  • backend api
  • front end ui/api
  • server runtime

  • front end
  • back end
difficulties faced
  • error handling errors - vague error message in node. best ones are those with the file names
  • data structure. if it doesnt match, does really throw an explicit error
  • local storage of token and redux - had some issue persisting the auth token
  • long codes are difficult to trace
  • redux, react-redux, usereducer - which one to use?
  • state - instances for - initialising, prefill and onchange onsubmit - react forms are so difficult someone made a implementation in npm
  • nested data structures
my conclusion
  • i still dont know how state works
  • how immutable state works
  • i think basically you dont touch the state directly but store it in instances
my unconscious
  • last night i dreamt of working in a deadend job. as usual, i hated the interaction with people i just got to know. usual fear of trying to absorb the job related knowledge on the job, afraid of people's disapproval, afraid you are not cool enough for people. even the cafe and the food was in detail. such a realistic dream. usually my dreams are rather indirect and vague. all that exercise from tracing and shooting coding errors must have sharpened my thoughts and senses.
favourite habit apps
  • google keep - checklists
  • tick tick - calendar view of list of actions
cooking, and eating my own cooking
  • made some aglio olio. garlic / chilli scented oil was done in the air fryer with chopped chunks of fresh garlic gloves and frozen de-seeded chilli padi. smell = good. spaghetti - done just right with the correct amount of water - 80% level, salt -2 teaspoon, timing -20 mins, spag - 1 grab broken into two, fryer - 7 to 10 mins - gralic was slightly browned. just the scented oil over the spag. toppings like mushroom and prawns - optional.
  • i have been having wholemeal bread slices with airfried egg. grease the bottom and sides of a dry deepish porcelain bowl with two tablespoons of oil by swirling the oil around. crack the egg without breaking the yoke and swirl again. 4 mins in the fryer. drizzle dark soy sauce.

green tea bitch

let me tell you the story of a green tea bitch and a hamsum with cheater potential.  i work closely with greentea in office. greentea has/had a long term boyfriend if more than 5 years (not sure if they still together, greentea always winces when i ask her about mr i-seriously-think-you-were-cuckolded nowadays). but she also crushes on the now ex-tech lead mr suave. suave probably left to avoid suspicion? i remember seeing her and her mr cuckolded boyfriend, she was cosying, rubbing her body against mr cuckold and leaning into him talking, on the mrt on our way back, from one of our get togethers. also knows he buys her hundreds dollar worth gifts on her birthday. (actually not very expensive i guess, she is into expensive gifts). ms prettii and mr suave ever played accidental touch ( hand brushing as they both reached for the mouse, then longing looks). she sent him a sticker of fingers touching on group chat before. anyway suave decided to teach us newbies coding in chinese (cos he s

this just came out. his recent songs are getting better, i'm impressed. metaphors and imagery on point. flying, running barefoot, looking back, blackened nails, tears in sleep, warm bright sunlight, dancing alone, flying free like a bird i relate to this because my life is to be honest, so-so in the friends department and non existent in the romance department.  i don't feel like really sad, or regret, or i need to change it. friends are busy and settled down,  some are less able to provide a listening ear (maybe to them it is childish, immature, or being listened to means you have have to reciprocate so maybe not, they have theirs at home already, they are stressed and have no more bandwidth for anything else).  that is the reality of being an adult. maybe the occasional sympathy and warmth from a colleague or friend or stranger. but that doesn't do it for me. i don't need the superficial. and i feel it is so easy to have values not align one day, or per
