I build a weather app this year which shows you a heatmap of when it is sunny over the next 10 days, hour by hour.

This is particularly useful for colder countries as I just want to know when the sun is out, regardless of temperature.

Picked it up again this month.

Decided to remove the 'full-stops'

Thanks for the feedback.

It's far from ready yet but this feedback has given me some impetus to refine the end product.

Description on the tin.

I found it hard to get fares and timetables for the Elizabeth Line in London between X and Y quickly hence I built this as an experiment using AI tooling.

Hi, thanks for the feedback.

Yes considering / implemented both of those, but will likely put it behind a paid service (need to pay for it somehow).

http://schoolholidays.deals/

A UK-based flight deals service aimed specifically at parents who can only travel during term-time.

Having this issue myself now with two children whereby flight prices double going into school holiday season, I have always wanted some kind of service which alerts me of good deals.

I still have a long way to refining the actual product, but trying to fit the development around work commitments. AI helps obviously, and does 90% of the coding.

Show HN: Elizabeth Line Guide (London) – Live departures, timetables, fares

https://elizabethlineguide.com

Hi,I built this as a little side project as I had the following issues when travelling on the Elizabeth Line:- Hard to get live departures for my destination/line - Hard to get timetable times (which I need when I get off a flight at Heathrow and need to find if I can catch the next train) - Hard to get fare information between two stopsI took a look at the keyword stats and there are not too...

Show HN: Askbyemail.com – Send an email, get an AI answer or summary (no signup)

https://www.askbyemail.com

Hi,I built www.askbyemail.com after getting tons of wordy emails from my kids' schools that I had trouble reading on the go.I know there are tools like Gemini (which I have not found to work that well) which can summarise email, but I thought 'what if you could just forward to an inbox and get a summary back?'.So I decided to build it - you email [email protected] with either a long email or a...

Show HN: Sunny Hours – an iPhone weather app with a sunshine heatmap

https://apps.apple.com/gb/app/sunny-hours-sun-by-hour/id6758806008

Hi,I’m a long-time HN reader, though I don’t post much.I recently built an iPhone app called Sunny Hours. Living in the UK, I’ve often wanted a weather app that shows, at a glance, when the sun is actually likely to be out.I built it because I found that existing apps often gave me lots of forecast data, but not a quick answer to a simple question: when is the nicest part of the day/week likely...

Re:Is anyone using PyPy for real work? on Monday July 31, 2023 @09:31AM (#36942196)
I've used it at work to speed up some standard Python code (without any c-bound library usage). It sped up the code by 5 times.

I've deployed used the pypy:3.9 image on docker.

One thing I did notice is that it was significantly faster on my local machine vs when I tried to deploy it using an AWS lambda/fargate. I know this is because of virtualization/virtual-cpu, but there was not much I could do to improve it.

I did try PyCharm a few times, but it seemed too complicated - and this was after using Visual Studio for 15 years!

The debugging support in VS Code is fairly good, so it's just the refactoring I'm missing.

I'll give PyCharm another go when I get some spare time.

I moved/was pushed over to Python around a year ago, after writing C# for 15 years.

My Python setup is as follows:

* vscode

* pylance

* black formatter

* flake8

* python typing annotations used as much as possible

This seems to work very well with regards to autocomplete and preventing run-time errors.

One thing I do miss is proper refactoring support.

Re:The Serverless Revolution Has Stalled on Monday October 12, 2020 @05:09PM (#24759473)
I agree. I only generally use Fargate with containers, and control with cron or with always on APIs, with Cloudwatch for monitoring, and it’s seems like a good midpoint between ec2 and serverless.

The APIs cost a bit more a month (they’re on quite low cpu/memory) because they’re always on, but it minimises complexity and it’s nice to know that you can move those containers over to another platform if needed.

Are people that callous?

I work for a large corporate, and I can honestly say that I think no-one would make such a decision. Perhaps I am naive.

Re:Ask HN: Have you ever regretted working on a product? on Wednesday November 21, 2018 @03:54AM (#18501167)
I've tried to grapple with this notion over the last 10+ years. When I entered finance (I work for a derivatives trading desk), it was just as Facebook etc were just starting and were becoming the 'cool' places to work.

However, nowadays the banking tech sector here in the UK seems to be more mature. Our traders are quite often from a STEM background which gives them an understanding of technology, and they don't adhere to the dicky stereotype you often hear about. But most of all, I've always found my tech colleagues to be extremely smart but also down to earth, pragmatic and meritocratic which is the reason why I've ended up remaining in banking.
