- 26. 26 UNCONSCIOUSINCOMPETENCE we are noteven aware of thelack of a skill One does not understand how to do something and does not recognize the deficit.
- 27. 27 CONSCIOUSINCOMPETENCE we are awareof thelack ofa skill One does not understand how to do something, but they recognize the deficit, as well as the value of a new skill.
- 28. 28 CONSCIOUSCOMPETENCE we knowhowto do something One understands how to do something. Demonstrating the skill requires concentration.
- 29. 29 UNCONSCIOUSCOMPETENCE skillis second natureand teachable One has had so much practice with a skill that it has become “second nature”.

Editor's Notes
- Hello people, thanks for having me. Glad that we found a way to still hold this conference CodeConf is about best practices I wanna talk about how best practices are killing our babies I have audience interaction => chat Let me introduce myself first
- Name FE engineer Culture Gardener Other things Podcast moderator Facilitator which is moderator with benefits e.g. company wide meeting each week Obviously spaeker Stuttgart
- Digital products for passenger cars… (…) Mercedes-Benz AG is like a mother to us, a little bit old-fashioned and slow but we still love them. Three office locations Stuttgart, Berlin, Lisbon Starts with website Also app like Bertha Gas station
- Our over arching purpose
- A lot to consider when it comes to babies Yes, that’s my daughter “flex” There are a lot of best practices when it comes to parenting babies List of articles Audience interaction: “Who has a baby?”
- Side Projects Are Our Babies
- Everyone has a baby Side projects First we get caught in perfection Second we never start an idea Picturing chat with friend Audience interaction: “Who has unfinished side projects?”
- You are not alone. A little bit data. Survey from 2017 among employees from big tech companies (Netflix, Google, Apple etc.)
- GH Archive states
- Made a quick survey in our company People should state how many side projects they have How many are abandoned MB.ioneers is how we call ourselves
- So, why is this the case
- As already said, best practices There are too many Let’s look at the tech stack to consider
- Big thing is infrastructure Where and how to deploy Automation (CI/CD stuff) Testing 100 % coverage, E2E testes and unit test Code paradigms – of course Frameworks especially in web FE Same for libraries Meta tool stack like IDEs, CLI tools etc. This list goes on and on Best practices all over the place But why do we even bother? Psychology behind it
- It’s hard to expose oneself Impostor syndrom Yes, people will judge
- The thing is people don’t want heir abilty get judged Joseph Ferrari a professor for psychology DePaul University researches procrastination And found …
- … (read) Story from dog school/dog training I’m there since well above one year New guy with dog named whiskey About 2 years old Whiskey did not obey at all Commands didn’t do anything I mean was the first lesson Asked me how long I said Looong He said above half a year Yeah, well above one year even He said “Thank god, hearing this tells me that we do not that bad” … Bummer Well, you see, he judged my ability and did not appreciate the countless ressources (effort) I put into the training of my dog Thus this feels bad
- You put time into this You needed to research It’s hard to just give it away Without getting anything back
- I was forced to use this picture We are all above average coders here, right? So we always provide smell free code, right? Did you know that in the most recent Stackoverflow survey 80 % of developres considered themselves to be above average? ;)
- Stumpling from one topic to the other Gets repetitive And long-winded Thus bores you The hype will fade
- Learning takes time Just imagine Even if you spend 3 hours a day Researching will take up 3 days This adds up
- Okay, it’s like that But what now? What do we need to do, to overcome these issues? How can we actually finish something?
- First of all A lot of psychology Motivation, discipline etc. We only eliminate one part: best practices
- MVP definition Minimum Viable Product (bare minimum of features) Less is more Very little Let’s say we wanna build a car Just 4 tiers which are somehow interconnected It will drive
- For the next step a brief introduction how we learn It’s a widely accepted concept nowadays Four stages
- We are not even aware of the lack of a skill e.g. Keyboard layouts Audience interaction: “Who is using something different than qwertz or qwerty?”
- Now you learn something from me Qwertz and qwerty suck Non ergonomic (value) DVORAK, Neo 2 for German
- You start to change layout You start to train But it is super hard You need to concentrate
- Type without having to think Can be performed while doing another task Is teachable You need to reach this stage with one thing in order to question it and come up with new things
- That’s how we learn We apply best practices we internalised That’s what we should accept Others don’t matter for now There is always ”the next best practice we do not know” Best Practices are always changed and created Focus on the things you can do Not the ones you can not
- Or in the words of my friend Sumit Most important aspect Ignore any best practices you currently do not respect naturally
- Implement the MVP Goal With current skillset
- Most important aspect is to DEPLOY I cant’t stress enough Means you have something usable You can share Yoa have a basis to iterate on See and feel your app Deploy can me various things (web deployment, compiling and providing a download, bake clay etc.)
- Very little Small/doable goals are key
- Aquire the needed skills for next goal
- Super important
- Repeat Again
- Have I already told you that Super important
- Summary Repaet till the day you day Software is never finished Pair with other techniques (like reserving an hour on Mondays) Again we focus on one aspect only
- Now Examples Sorry, my talk is only “nearly” code free But it’s not important to understand this function It’s a piece of code from a Github repo out there It’s a code which does not respect current best practices Brief description of what it does Let’s have a look at the current best practice
- We use new Set Set is new API Nature of it is to only hold unique elements Array in constructor Cast to array again Boom done This is not how one would do it
- A realistic aproach Most developers would currently do it like that I would say It just filters the array for duplicates Only first index stays
- Do not think about whether you understood the code or not It’s just 3 functions to remove duplicates Performance benchmark Readability also consideration Turns out realistic one is best Best practice not always best However original is a code smell nevertheless
- What repo did we look at? Audience interaction: “How many stars does this repo have?” Less than 100? Between 100 and 1,000? Between 1,000 and 10,000? More than 10,000? And you are absolutely right We looked at Vue.js Star count of more than 150,000 My point is that every repo, every product has technical debt
- Another example I challenged myself Red slide You can check it out by scanning QR code or using the URL
- This is the app In the video you can see permanently stored (refresh of browser) I can add recipe and delete Super ugly but One step ahead of all products in here Nice basis to iterate on e.g. my next goal – Custom URL? - Backend? No, choosing data enrichment of recipe Case Local Storage API
- Why don’t we face this at work? Is it solved there?
- Gladly, it is *pooh* First of all we have more people and more roles Do not need to be an expert everywhere But more importantly…
- Scrum! This whole “iterating” thing might have given it away What do we do? We iterate And you know what one of the most important measures is? Every Sprint needs to produce something deployable You do not need to deploy But it need to be deployable if you wanted to
- Bob Martin author of the agile manifesto Recently in the Changelog Podcast Red out loud That’s how we avoid this problem at work
- So to conclude this Clear your mind
- Pich up your baby again As soon as your at home
- And don’t forget to
- DEPLOY Cause it’s super important!
- …
- And send me your achievements! I’m serious, please keep me up to date what you’ve achieved through my talk Would appreciate any inquiries
- Here are the contacts you can send it to My Twitter LinkedIn (via my name which is Kai Klostermann) And for a less publicy exposed way you can send me a mail to i made this at really fast dot biz Thank you so much! Take care
