Yeah, I use Chrome myself, so compatibility in Firefox breaks sometimes. (and I forget to check that it's working there more often) I'll look into it relatively soon.

As for the submenus not closing when you re-press their sidebar buttons, I just haven't coded that yet. Should be a one line change, so it will probably be added by tomorrow. Thanks for checking it out.

EDIT: Okay, I tried opening it in Firefox, and could not reproduce the "black boxes" issue in your screenshot. What version of Firefox are you using? Also, I've now updated the submenu/sidebar buttons to close the menus when re-pressed. (and updated their appearance a bit)

It appears I can't replicate it either. I may have updated Firefox since last week or something? 54.0.1 (32-bit) is my current version.

Hey everyone! It appears I'm six years late to the party, but better late than never.

I've been building a website for the last few months which is very close to the ideas presented in this article. I've summarized some features of it, and added an entry to the wiki page:

Debate Map: Web platform for collaborative mapping of beliefs, arguments, and evidence.


  • Collaborative creation, editing, and evaluation of debate/argument maps.
  • Open source. (under the MIT license)
  • Developed using modern web technologies. (react-js, redux, firebase)
  • Built-in probability and validity rating, and calculation of argument strength from these ratings.
  • Tree-based structure which can extend very deep without loss of clarity or usability.
  • Integrated term/definition system. Terms can be defined once, then used anywhere, with hover-based definition display.


  • Has a learning curve for casual users, as content must conform to the argument<-premise structure at each level.
  • Performance is currently less than ideal on mobile devices.

I'm the sole developer at the moment, but I'm very invested in the project, and plan to spend thousands of hours on it over the years to make it the best it can be. I'm very interested in your feedback! I've been a silent reader of this site for a couple years, and it'll be neat to finally get involved a bit.

Machine Learning Group

After signing up for this post, those of us that want to study machine learning have made a team.

In an effort to actually get high returns on our time we won't delay, and instead actually build the skills. First project: work through Python Machine Learning by Sebastian Raschka, with the mid-term goal of being able to implement the "recognizing handwritten digits" code near the end.

As a matter of short term practicality currently we don't have the hardware for GPU acceleration. This limits the things we can do, but at this stage of learning most of the time spent is on understanding and implementing the basic concepts anyway.

Here is our discord invite link if you're interested in joining in on the fun.

Before even reading it I was confused.

Epistemic status for the first part of this post:

[image of thinking woman in front of math]

Epistemic status for the second part:

[Image of greek? philosopher preaching]

Admittedly I should probably know who the second image is of, but I have no idea what they're trying to say with either of these.

As we say in the Bayesian conspiracy: even if you’re not interested in base rates, base rates are interested in you.

No. Stop. This is just awkward to read.

Note: Everything I write below about pedagogy is anecdotal, and I don't have much experience outside of being a student.

This is a really cool idea! I think it's a good way of bringing people in the community closer together!

That being said, I'm worried the classes might not turn out to be very good because good teaching seems generally pretty hard. (Which isn't to say that I don't think LWers can't rise to the challenge, just that this means my priors on "Video tutoring will turn out well" are low.) (Or perhaps I just didn't have many good teachers).

I think personalization could be a very important niche role we could exploit here to make things better. So rather than the Teacher spending time going over the subject, they could chat individually with Learners to assess where they are at, suggest materials, and then follow up after each iteration. (Think something like the flipped classroom model where we're counting on people to be self-motivated learners, and these video sessions would be more for supplementing self-studying.)

I suspect this will end up being something more akin to self-study groups that produce teaching material as a direct result of learning the material themselves. For example, writing up an explanation of how to do a particular book example. This doubles as an assessment of people's skills since other people that know the topic really well can build on those explanations or correct mistakes.

With a series of such explanations, anyone else trying to go through the material will have a clearer pathway for the level of understanding of a given sub-topic they need to develop to progress: the exercises and readings needed to be able to understand something, or do a particular difficulty of project.

Teach a man to reinvent a wheel every time he needs one and you'll have a lot of funny wheels (and not much of anything else).

This points to a need of looking for, building off prior work where possible.

Taking it a step further to generate a method of meta-solving this problem: there are many parallels here to programming and device connectors of old (phone charger or other standards). I would imagine we could look to how those sorts of problems were solved and apply or derive the analogous technique here.

It seems to me that the sadistic simulator would fill up their suffering simulator to capacity. But is it worse for two unique people to be simulated and suffering compared to the same person simulated and suffering twice? If we say copies suffering is less bad than unique minds, If they didn't have enough unique human minds, they could just apply birth/genetics and grow some more.

This is more of a simulating-minds-at-all problem than a unique-minds-left-to-simulate problem.

What's wrong with gold stars for everyone who makes a non-spammy, coherent point?

Comment author: Regex 20 January 2017 05:10:18AM *  1 point [-]

Comment being non-spam and coherent is considered a bare minimum around here. Using the rule of upvoting nearly everything would induce noise. With the current schema of being a signal of quality, or used to say 'more like this' (not necessarily even 'I agree') provides a strong signal of quality discourse which is lost otherwise.
