I would really love to ditch more of my nvim setup for vscode, but this bug [1] from 3 months ago absolutely wrecks my productivity. I rely on splits as the primary means to navigate the codebase and having a single cursor position per file

My startup's monorepo has 2 root commits as well. When the company was first starting out, my co-founder and I created independent git repos. I was writing OCR type research-y code and he was doing more traditional CRUD REST webserver

Cool, I didn't realize that. Thanks for the correction. I should mention that this was back in September 2014, where IBM was the only one offering anything in Canada (hence the migration). Once we'd done all the work to decouple f

This seems to be explained in better detail by https://bo0om.ru/chrome-and-safari-uxss . Working via Google Translate, the claim seems to be that using MHTML and XSLT allows you to bypass the sandboxing rules and inject Java

Yeah, I personally find this sort of syntax convolution ugly and hard to read but I thought it relevant. Enough rope to hang yourself with and whatnot.

Since you're using Python for your example, it's worth mentioning that 3.5 extended the unpacking syntax [1] to sort of do what you want. foo = { 'a': 1, 'b': 2, **({ &

We use StackExchange's blackbox [1] to check in GPG encrypted secrets into our monorepo (contains both ansible deployment playbooks and the code itself). This way, we can introduce secrets and the code that uses it in a single commit!

They are the "same" by equality, but that's not the only relevant comparison. Ordering is important if you want lexicographic less than. Without ordering, you wouldn't be able to sanely run `sorted` on a iterable of name

For background, my startup has been using CoffeeScript since August 2012. A quick check of our git monorepo says that we have 130k lines of code at HEAD, and have probably thrown out at least as many lines in rewrites over the years. I have

One advantage of the template approach is it allows for test level parallelism, which may address your primary goal of performance. > Waterline queries are case insensitive; that is, Users.find().where(name: 'FOO') will turn in

Wow, this looks like a much better version of something we attempted for a hackathon [1]. I'm probably going to spend the weekend spelunking through this! Is there a more detailed write up of the inner workings floating around? [1] ht

Just a quick tip, you would want to use `less -R` (upper case R) instead. `less -r` allows all raw characters which makes it difficult for less to maintain screen appearance. From the man page: -R or --RAW-CONTROL-CHARS Like

I called it funky because `x` is never local to `inner`, but gets an entry inside `locals()` if `inner` uses it implicitly or explicitly with `nonlocal`. Non-funky behaviour would be to have an `enclosing()` that walks up the outer function

by rraval 12y ago
Note that `locals()` actually does funky things around enclosing scopes. Consider the following Python2/3 code: def outer(): x = 1 def inner(): print(x) print("x = {x}".format(**l
