How do you approach knowledge gaps?

Maniflames on January 13, 2019

It's normal to get stuck from time to time when you are trying to build something. However, when I make the same mistake again and again I know it ... [Read Full]

A low tech solution to this that I use is to use post it notes stuck to the bottom of my monitor, as I work I add a note to the screen if I make a mistake, or I lack knowledge of something. I continue to fix the issue and then at the end of the day I get the notes together and can see my gaps in knowledge or stuff I need to remember.

This takes the guess work out finding gaps in my knowledge, I can then prioritise the gaps.

 

This is a great one! Thanks for your low tech solution, I'm going to try this out 😁.

 

I find sometimes that a lower tech solution is better than an app or something fancy, I tried using a timer on my phone for pomodoro timing, but i spend more time setting it up than working, so I just use outlook to set 45 minute meetings with my self. This makes Lync get my status, plus people can't book meeting for the next 45-60 minutes so it works much better.

I guess in some ways we fall in love with a certain level complexity and totally forget there are easier ways to do certain things. I've noticed that blocking out time in my calendar was effective as well for the same reasons. (Also I had no idea what Lync was so I googled it, Microsoft some software solution for anything πŸ˜‚)

THIS! this has been me since starting out as a (solo, anyone want to partner?) startup, I always end up starting a project to say, save my code snippets... there are literally 1000's of FREE solutions that I could use just to realize the amount of time I've wasted because I wanted it done MY way.. unfortunately I don't do so well with gcal or lync as I need to visualize the knock on effect it will have on my projects and have resorted to kanbans for a ONE PERSON company. πŸ™ˆ

 

I'm still learning to dig myself out of knowledge gaps without asking my manager for assistance, and I have a question to hopefully bring this discussion even deeper:

How do you balance filling in your knowledge gaps on your own (be it StackOverflow, tutorials, etc.) and getting your assignment in under the deadline? I am currently using time boxing to try to work through something on my own, then I approach my manager for assistance when I've been stuck longer than my allotted time.

 

Great technique!

To be honest I don't have a solid way of balancing these things out.

Usually when something is wrong I try to find the root cause. Through debugging, googling and trying to find a related issue or pull request on Github.To make sure I explain everything that I have learned I keep track of the whole process by writing new insights down in my notebook.

If I run into a session like this at the end of the day, the stand up the next day is when I ask for someone to help me out. If it's in the morning I'll ask someone to help me after lunch.

The only time I ask for assistance outside of these meeting points is when I run out of 'leads' and unable to understand or find the cause.

I have tried to limit this process to an hour in the past but I'm really stubborn at times, when I think I'm close I stretch it for way too long πŸ˜….

It doesn't happen too often that this goes on for way too long but there are still some occasions soooo πŸ™ˆ....

How long do you usually make your timeslots before asking for assistance? And how do you avoid the trap of: "I'm really close though, I got this just a few more minutes" ?

 

Hey, thanks for the reply! I try to stick to a timebox of an hour or two as well, depending on how complicated the issue is. If it's feeling like I'm really close I'll give it another 10-15mins and then take my findings to the manager or more senior developer and tell them what I've got and ask if they have any input on how to get to the next step. I'm the same as you, I'll go on all day if I feel like I'm close and "just need a few more minutes" so I really try to be disciplined about it.

Pomodoros are actually a great way to timeblock and not let yourself carry on all day - give yourself until the end of your current/next pomodoro period to solve it, and if you cant, it's time to recruit help.

This is definitely one I'll have to practice but it will be worth it. Thanks for the advice 😁.

 

I take notes about the comments in my PRs. What types of feedback am I getting? Is it a small mistake I made (Forgetting a preferred format once or twice) or is it a consistent comment I am getting. If it's consistent, that helps me a ton to figure out where my gaps are.

Right now, my gaps are writing jest tests. I am transitioning to writing React components from scratch + d3 from Drupal development. I have experience with React and jest, but not writing them from scratch. I take notes of where I have good instincts (where someone likes what I did) and where someone comments that it could be improved.

I am pretty active about asking questions while coding too. I tell my mentors "This is my instinct/gut feeling, but I want to make sure I am not going down a rabbit hole." This helps me TREMENDOUSLY :D

 

This is a strong idea, others often see what you don't. Sometimes it's very easy to look at feedback, nod and forget about in no time. Taking notes while receiving feedback + being active about asking questions are things I should do more often πŸ˜…. Thanks for the advice Lindsey 😊

 

You're welcome! I didn't go through any formal training in web dev, so I find random gaps in my knowledge all the time. I'm almost an expert at finding my knowledge gaps πŸ˜‚

 

+1 for the rust resource on ownership as it is a unique concept not just in other ML based languages but across every language, although for me it makes a little bit more sense that pointers an references
in C based languges int **my_Number cause optimization??? felt like it should just be the default to rerfer to a pointer that refers to a pointer that referers to a place in memory the amount I used it - admittedly when C++14 was the newest standard and I was 15 and moved from Java and VB6 and was probably doing it all wrong.
Rust seems to have got it perfect, you just need to get to know life times and ownership and the rest is syntax and keywords.

while async -> await is one the best things to happen to javascript, no more having to call setTimeouts in the days before anonymous functions. - I really am showing my age - and realising you've just called the function in the setTimeout not passed it a reference to the object of the function. thanks ECMA for the 10 year gap between standards :') and while I now love Typescript it had promises which weren't much better than setTimeout or setIntereval.

I found over time I fell into work arounds that were possible at the time (i.e. relying on events, of which there were only about 8 at the time; load, click, scroll, hover, error.) which was not really something you want to get into the habit of - the workarounds - as they stick and lead to a lot off time wasted retraining your brain when the next standards are released, take it from a 28 y/o who started when he was 9 and we booted to MS-DOS from a floppy disk, ahh i really wanted the upgrade - a whole 10mb

in one "zip drive" to..
So +10000000 to anyone who is doing this and recognizing their weaknesses and fixing it BEFORE you end up picking up bad habits and have to spend weeks undoing years of small habits!

 

Thanks πŸ˜„

Ownership, Borrowing & lifetimes are really powerful but definitely take time to get used to (espacially if you come from languages that don't have manual memory management). Don't know a lot about C so catch me if I'm wrong but I also feel like what makes Rust special is that it forces you to think about how memory should be managed in a specific way rather than leaving it all up to you.

I also really can't imagine writing asynchronous logic in JS without async/await or promises. I started programming in js right after ES6 released. By the time I wanted to do asynchronous stuff promises were really populair. ES6 is truly a blessing when you compare it to ES5 but I've also noticed that it can be a lot easier to think about how js works under the hood if you ignore some ES6 features while trying to get a deeper understanding of javascript.

Never used a floppy disk but hopefully people look weird at me in a few years for using USB-sticks as a kid :')

 

hey Imani! Personally my approach is mostly: research the crap out of it πŸ˜„

I’ve found it also helps a lot to write/teach about what you learned (even if it’s just your assumption of how you understood it). It puts you into a position where you likely don’t want to get it wrong, while at the same time, it’s okay to get it wrong. And maybe someone points you to right direction.

Bonus points: create a POC based on what you’re learning or trying to understand.

I think just being in a position where you’re willing to ask (like you’re doing now) about things you don’t understand already puts you in the right path. Somestimes growth comes more from being able to ask the right questions, and less so about knowing the answers themselves (that’s what google’s for πŸ˜†)

 

Definitely agree, google is our best friend πŸ˜‚. Sometimes it's kinda hard to ask the right questions but I guess that is a skill you improve over time. Thanks for sharing 😁
