Ask HN: What "weekend project" will you work on this weekend?

I'm trying to turn Emacs into an outliner that can natively read/write OPML files. After asking #emacs today, I think the key bit is using "format conversion" [1] to accomplish this.
I've finally gotten over the "beginner hump" when it comes to elisp and its becoming a fun little language to toy around with. I figure this'll take a good chunk of Saturday.

I love emacs, and I appreciate you taking the time to learn how to extend it.
I am working on a sales CRM made with Node + Angular. Things are going pretty well but still a lot of work to be able to compete with Pipedrive. I hope I can release it soon and see how it goes.

Put any url you like in there. It'll either work or it won't. /css/[url] kind of works too.
Also a random app in C# because I failed a midterm exam because I couldn't get runtime DB access to work from memory. Yeah I know, I still suck unless I have Stackoverflow and/or a reference right next to me.

I don't think you suck for relying on StackOverflow/reference when writing code. You just haven't completely understood or remembered what you're doing. After a few time you'll remember and understand and move on to using SO/reference for the next more complicated thing.
I am writing a toy lisp compiler as a learning experience. Its taking forever to get anywhere but I am finding the journey is more interesting than the destination.
I'm trying the garbage collector for the second time. My first attempt ate the stack and I found it hard to reason about or debug.
I'll try and finish the gc this time but I only recently realized that I didn't need to start writing one at all. For the first version I could have just allocated memory without deallocating.

I just finished an MVP of http://www.educatornews.net. It's an HN clone for the education community.
This weekend I'm focusing on implementing a "conversations" feature, similar to HN's "threads". I am also trying to increase test coverage, so I can agressively refactor my ugly MVP code as I begin to pick up users.

- Why aren't you using mptt comments?
- A one liner query is just called a queryset.
- To get all the "upvotes" of an user it's better to start from the user.
- I don't think your code is ugly.

> Why aren't you using mptt comments?
I have heard of mptt, but I had never used it before. I am intending to integrate mptt into the commenting system, before long. [0]
> A one liner query is just called a queryset.
Did I call it a query somewhere?
> To get all the "upvotes" of an user it's better to start from the user.
So rather than:
Thanks, that's encouraging. I was embarassed by my single 1000-line views.py file.

So rather than:
request.user in comment.upvotes.all()
comment in request.user.upvoted_comments
upvotes = models.ManyToManyField(User, blank=True, null=True, related_name='upvoted_comments')
Thanks, that's encouraging. I was embarassed by my single 1000-line views.py file.

> mptt
First time using mptt might not be straightforward. But I think it's worth because the problem is "difficult". Similarly django-polymorphic. Those are the two things in Django I would think hard before re-writring.
> one-liner ~ queryset
I don't find the particular comment right now.
> To get all the "upvotes" of an user it's better to start from the user.
I don't know the correct queryset, the one you provide seems good. Don't compute in Python what you can do in the db. In the particular code I'm referring to, several queries were done against the db instead of one.
> 1000-line is ugly
yeah, kind of. But at least you don't use abbreviations. Or 2 spaces for indentation. Seems like valid pep8.
I don't say that there are no mistakes in the code, just skimmed over it.
The file is big because some of the functions are not views.
- get_submission_age: should be template tag cf. https://docs.djangoproject.com/en/dev/howto/custom-template-...
- get_submission_set: I wouldn't use such a function. For sure you are iterating two times over the list of submissions, one time in the view, one time in the template so it's a "2n" so O(n) complexity. It's ok but only one iteration over the list is required. But the django template language (DTL) makes it "hard" to do it... DTL was built around the idea that the template writer is stupid and probably also that nobody would read the code the template writer wrote before going into production.

I'm working on a clone of a relatively simple but very fun mobile puzzle game. I'm creating it for Android using libgdx. It's my first serious attempt at making an Android app, and it's coming along nicely. This weekend I'll be trying to fix the scaling and cropping for different resolutions, which is something I ran into just trying to test my game on my own phone.
My garden.
CA is being hit with a drought, but we conserve enough water to not really worry about it.
My goal is to have enough raised bets and suitable seedling production/crop rotation to have at least 2 days/week of fruit/veggies from the garden between late april and September. Potatoes and a new raised bed were on tap. Seedlings already moving along nicely.

I'm working on a turn-based mobile game for iOS written in HTML5 w/ Cordova. Getting close to beta-testing time.
Trying to make a better protein alignment for transcriptome annotation using suffix arrays and possibly GPUs. Although it's a bit of a lie, that was the project I worked on last weekend, this weekend I won't have time, moreover I have tend to start a new project before finishing the old one....
A feedback system for my dad's restaurant that allows customers to provide feedback through text messages. It's a fun little side project with a few challenges, and I've enjoyed it so far.

I am working on springyRecords.

A Record Mapper for Java that runs on top of spring-jdbc.

I have no idea, I've got a free weekend and I've got my text editor here, I want to build something fun that will make people have a giggle..
I'm working on a site to create and share parallel translations, i.e a single book/document in two languages next to one another.
I'm in love with 2048, so I'm going to learn some game development and hopefully make a clone of it.
I'm going to work on an ncurses-based music player similar to cmus, in clojure.
That said, what side project will you be working on this weekend?
