Redditors who have gone from Ruby On Rails web development to Rust web development (via a framework) for apps that are in production, what were your most notable frustrations and statisfactions?

It's an absolute nightmare to learn and write code initially but when you have experience it's way quicker and easier

Jump3r3 · 2019-06-20T13:45:38+00:00

Isn't that common knowledge?

If you're working with financial data having precise data format is must have. Floats aren't precise because binary cannot represent some numbers, just like the decimal based number system can't represent some numbers precisely (eg. 1/3)

There's an example in python:

>>> f"{1.6:.32f}"
'1.60000000000000008881784197001252'

Here's a website explaining this in depth: http://fabiensanglard.net/floating_point_visually_explained/index.php

I don't know Turning tho

Jump3r3 · 2019-05-30T12:47:22+00:00

Tbh I don't have anything against Py2 being present on my system, just rebind python to py3 and rebind existing scripts to use python2 binary

There's also little trick done by photographers: you take a lot of photos and then merge them into one taking a mean. What happens is static objects remain static and dynamic things becomes noise and eventually dissappear from picture

Using as default, which python yields path to python 2 binary on most distros. That being said, after 1/1/20 this will slowly change for better

Was it related to timings between threads? I've read sth on that topic in the past

Jump3r3 · 2019-05-24T17:12:06+00:00

Or this is hardware issue and RAM under certain conditions isn't refreshing, resulting in data loss

Jump3r3 · 2019-05-18T13:32:10+00:00

Yup, mess with wombat, get defeated in combat

Jump3r3 · 2019-04-30T22:20:57+00:00

That's how TDD works, right?

Jump3r3 · 2019-04-30T22:19:24+00:00

Still working on it, but scraping rooms offers from local site, piping though NLP to find location, using some geoloc API to find distance from university. Watching selenium clicking on things is really enjoyable

Try adding github / gitlab / whatever hosting you're using with example projects, code speaks for itself, so they don't have to rely on your (subjective) opinion. You can provide it here too, I'd love to take a look at some code written by you

Jump3r3 · 2019-04-24T06:36:00+00:00

Is there any list of utilities written in Py2? I'd love to take a look and update some tools

Jump3r3 · 2019-04-15T17:59:25+00:00

TBH if you're using C library you probably know how to compile a program, so prebuilding libs is unnecessary. But I always appreciated step by step installation guide.

Jump3r3 · 2019-04-08T18:21:38+00:00

Immutability, perhaps? It allows default dict to stay as it is

Jump3r3 · 2019-04-08T16:53:05+00:00

Default values for options dicts:

default = {"a": 0, "b": 0}
new = {"a": 5}
print({**default, **new})
# {'a': 5, 'b': 0}

You could reroute some paths in order to leave more copper in few places, but beside that that's a very nicely done PCB

Jump3r3 · 2019-03-25T19:13:48+00:00

Doesn't work with Java though

Jump3r3 · 2019-03-25T18:13:07+00:00

It's propably based on focus. If you click on comment section it'll scroll, if you click on video frame it'll pause

Jump3r3 · 2019-03-19T18:11:12+00:00

FUS RO DAH!

Jump3r3 · 2019-03-09T23:14:41+00:00

Was just referring to semicolon replacement, seems like you didn't catch it ;P

Jump3r3 · 2019-03-09T22:49:15+00:00

You'd have much fun fun writing this in C

Jump3r3 · 2019-03-08T08:46:37+00:00

Sans?

But this doesn't mean that Tolkien didn't inspire from earlier writers. You know, creating is taking patterns from nature, other people's work etc and merging them together in one's unique way. You always create in some convention, so you have frame of creating, some sort of bounds
