  • Some Thoughts On Taking Notes

    Some Thoughts On Taking Notes

    I read this article by Ben Casnocha on taking notes, and whilst my previous note taking had been somewhat sporadic, this motivated me to step it up and take notes at every talk I attend. I’ve also been taking more notes when I read, taking time at the end of every chapter to add some takeaways to a doc on my phone (this makes the chapters I don’t get much out of more apparent – I have nothing to write).

    I write these up on my blog where possible (and permissible), although I confess I’m far behind on this. This was originally just to have a place to put things, but sometimes people find it useful – this talk from GHC, for example.

    Definitely, it improves my retention, and also (if I managed to post them) it gives me something to refer back to. I don’t type, because if you’re using a laptop the assumption is not that you’re taking notes, and it’s too easy to multitask, so maybe I wouldn’t be (also laptops are heavier, with worse battery life – I don’t usually carry mine to talks). Usually, I use pen and paper, but sometimes (like when I use up a notebook during a conference! Or a pen!) I use the notes app (just the regular one) on my iPad or iPhone. This has mostly been fine, although I did lose a bunch of notes using my tablet once. I don’t know exactly what happened – my attention was split between the keyboard and the presenter – but it wasn’t possible to undo. I was really sad about that, it was a really interesting talk. And haven lost all my notes more than half way through, I didn’t know what to do – taking notes on the second half just seemed redundant. I actually prefer taking notes on my iPhone, because I’m closer to touch typing there than any other device, including my Android Nexus 5.

    So most of the time I end up going over them again before I post them. Whilst technically inefficient (double touching!) this is sometimes when I get the main value of the talk – I see the full arc better, recognise the key points, and go and look at the extra resources that get mentioned. It’s where I see the links between the start and the end, and the narrative that the speaker constructed, if they did construct one.

    One thing that taking notes has highlighted to me, is how little content many talks have. Taking notes separates the delivery from the content. Some talks are in many ways great, and full of information, jump around too much and would benefit from adding a coherent narrative that ties it all together. Another example is that recently I saw a talk that I think had I not been taking notes I would have been really impressed by. The speaker was energetic, charismatic, and passionate about what he was doing. But in black and white, pen to paper, it was clear to me that this was just a talk about White Male Privilege (good article on life hacking and WMP). It didn’t really have that much value.

    (Maybe I could reduce the backlog by removing that kind of talk from my todo list).

    I need to get better at keeping up with what people say, I am not good at writing and thinking at the same time and tend to pretty much take down everything they say almost verbatim rather than pulling out key concepts. A lot of people talk very fast, although my (unscientific) observation is that the faster people are talking the less of what they are saying I need to take down. Speakers who have a moderate pace, are actually packing in more content.

    Anyway, approaching a year into this experiment, I see more and more reason to keep at it. Because I think it’s made me a better speaker, too – I think more about what are the main points that I want someone to take away, now. I work harder to tie things together.

    The only downside? I gave a talk to my team, and everyone politely shut their laptops. And I was a little disappointed that no-one was taking notes.

    Women in Computer Science: It’s a Hard Problem

    I've always considered women to be people

    There’s this class of problems in Computer Science, called NP-Hard. The short explanation for this, is that these are some of the most difficult problems in the field, where solutions are likely to be exponential in time.

    One such problem is the Travelling Salesman problem – finding the shortest path on a graph (or a map).

    But you don’t see anyone writing:

    I’ve solved the travelling salesman problem! It’s possible that it’s not always the best option to take the shortest path from a given node.

    Because that would be stupid. They haven’t solved it, they have provided one (in this case, useful) insight. But that insight is not new.

    And yet. It seems like I see this kind of post all the time when it comes to the lack of women in the field. This week it was about how hunting rabbits is like coding. And initially I just wrote it off because it is clearly so stupid… and then I realised, this is from someone who is pretty well known in the field. And that just made me really angry – because nice, reasonable men who want to help say this kind of thing is just crackpots, who should be ignored.

    But in this case, pretty famous person, who probably won’t be ignored.

    (Actually he got internet-lynched and then congratulated himself for “starting a dialog”. I call BS – there’s been a dialog for a long time, he just hadn’t noticed it.)

    I am so, so tired, of smart men who (I would like to think) mean well thinking the problem with the lack of women is that they have not previously turned their Towering Intellect to it.

    That is not the problem.

    We’ve had data, and literature, on what the problem is for a really, really long time now.

    Unlocking the Clubhouse was published over 10 years ago – there’s a lot of information there as to how universities can address the lack of women. Very few universities are really re-inventing the course as they need to – Harvey Mudd is this bright, shining, star.

    Delusions of Gender (Amazon) came out 3 years ago. It debunks the “neuroscience” and explores the socialisation of women. It’s an incredible book.

    AnitaBorg.org publishes studies on what helps recruit and retain technical women.

    When considering the problem of women, we need to build on the work that’s already done, the research that is already there. If you’re worried about retention, perhaps instead of trying to reframe and redefine the problem again, just address the problem that has already been identified.

    When I read articles about why women leave (last week’s favourite) I find myself thinking yes, that will be me; I will be another statistic.

    So, to the Straight White Males who write from their position of privilege. Like any other hard problem in CS, do your research first.
