hey, author here. I always find it weird to see HN posts where you have to pay to read what it says (what's the point?) so here are 6 sample pages from the zine if you're interested in seeing more of what's in it: * CSS isn&#

my understanding of US stock options for Canadians (and really for anyone who can't afford to exercise their options) is: - having ISOs is bad, you don't get any of the tax advantages that Americans get and it means that they expi

I wrote a custom Gumroad dashboard for myself. 2 things that have helped me: 1. de-emphasizing daily/weekly metrics. I find that a lot of my weekly / daily numbers are just noise, and ignoring them really helps keep me focused on

Also, this kind of profiler is great because you can use it on any running Python program, which is pretty magical and very useful. (especially when it's an application you didn't write) But it's not right for every use case:

thanks for pointing out the "might be attached to the steps they've taken so far" line -- that is condescending, and I've fixed it to make the point I was actually trying to make (don't be condescending! :))

yeah, I wrote this comment and then realized that I should add it to the original post too :)

it's really worrisome that they offered to look through your email data to confirm your identity. I'd be really curious to know more about what Fastmail does to safeguard customer data from malicious activity by employees.

I actually realized that this must be on HN because 2 different people emailed me to tell me this XSS workaround was bad advice :). Updated the post.

If you have an iPad and apple pencil, there's a really great app to do this called iFontMaker: https://2ttf.com/ . I used it to create a font from my handwriting that I've used extensively, and creating the font to

`group by 1` is actually allowed in several SQL implementations, and there's no reason it can't be -- the same as with column aliases the db engine can just rewrite select name, count(*) from table group by 1 as select

The main reason I hear that people buy zines from me is that they find them informative. I've honestly learned a lot about this from writing zines -- for example my bite size command line zine ( https://wizardzines.com/z

that's #16, though perhaps I should just say that the reason the response is empty is that Google is redirecting you. I'd love more suggestions for curl exercises though :)

I used about 350GB in the last month according to Cloudflare (over about 3.5 million requests), probably because I serve a lot of 5-10MB PDFs. Being able to not worry about bandwidth fees for a medium sized personal site is really amazing.

by jvns 7y ago
the main advantage for me is that Cloudflare's free tier has no bandwidth limit. Netlify's free tier has a 100GB/month limit ( https://www.netlify.com/blog/2019/02/26/netlify-and-bandwidt...

yeah I think this would be very possible! I think the hardest part would be the "with its arguments" part. But there's a really useful Rust crate called gimli for parsing DWARF (I found it a lot easier than the C DWARF librar

I'm on Linux. I did a tiny bit more investigation and it seems like ltrace works on some processes (like top) but not on other processes (like Firefox). I'm sure that the Firefox process in question is making library calls because

thank you so much! I didn't know about that and using those files looks extremely doable. I'd assumed that ltrace used DWARF or something like that to format arguments.

I can't speak for the job board, but there are dozens of full-time remote developers (including me, obviously), and I see remotes devs being hired frequently.
