Re:Designing Price Charts for a Portfolio Tracking App on Wednesday July 02, 2025 @02:37PM (#44447291)
I recently added price charts to my mobile portfolio tracker app, FINARKY, and wanted to share some of the design decisions behind them, like focusing on percent changes instead of raw prices or handling interaction.

Feedback welcome!

There’s a lot of work there! I’ve also developed a portfolio tracker as a side project ( https://finarky.com/ ). It’s much simpler, minimalistic (that’s how I like it), and at the same time provides the Personal Rate of Return, which I miss in other more-featured and cluttered apps (with features that i don’t need).
I don't know, but this Morningstar article from 2013 says...

"Even though personal rates of return are crucial numbers for any investor trying to reach a goal, few fund families provide these returns on investors' account statements. Why not? Many fund companies brush off any suggestions for improved disclosure by arguing that providing more information would only confuse investors, or by pointing to surveys showing that shareholders are satisfied with the status quo." https://www.morningstar.co.uk/uk/news/65362/understanding-yo...

In any case, for me, the PRR is the best measure I know to understand how my portfolio is performing. I don't think it's confusing... if my PRR is 10%, it means that a fixed-rate account with a 10% APY would have provided the same returns when applying to it the same cash inflows and outflows as my investments. I think that effectively communicates the performance of the portfolio (and lets me compare it with other portfolios, or particular investments).

Show HN: Finarky – Portfolio Tracker with Personal Rate of Return

https://finarky.com/

A minimalist portfolio tracker that calculates your Personal Rate of Return (using Internal Rate of Return, IRR).Although often missing in more featured and complex apps, the Personal Rate of Return is essential to know if you're on track to meet your investment goals, compare the performance of your different investments, or with other people's portfolios without revealing any specifics.This...

I think European regulations like GDPR or cookie laws have made the Internet worse, not better. They're not effective and make things more complicated for everyone.

I think that people in government should design rules to provide equal opportunities to everyone. I think that will benefit you even if you see yourself only as a consumer. I agree with what the article says, the European regulations only benefit the bigger companies, which have the resources to handle the red tape.

I think that when there's regulation, the problem is that sometimes filing a complaint may take too much time, and same for the police to check anything. It should be automated.

I submitted this to Hacker News some months ago, and seems relevant here...

Tell HN: Steal idea for product to automate reporting of barking dogs complaints https://news.ycombinator.com/item?id=19436807

(although I was thinking of dog barking when I wrote it, it's actually applicable for any kind of noise pollution)

I didn't like the adoption of Slack either.

I think https://clojureverse.org/ is a much better place for discussion.

Tell HN: Steal idea for product to automate reporting of barking dogs complaints

Barking dogs are one of the most common noise complaints everywhere.Reporting that to the owner or the city council, with proofs, may be complicated and time-consuming: it requires listening to barks through all the day, for days, recording them and keeping track of start time, end time, intensity... It's even more complicated if there's not one barking dog, but many spread across a...

Is all the tagging manual?

I assume that in order to find images of relevant outfits for the expressed "needs", the images have to be tagged with colors, brands, garment types... If that tagging is manual, I wonder if it could be automated using the object detection feature of an image analysis service like Amazon Rekognition or Google Cloud Vision.

Maybe automated tagging would allow richer tagging, and that could be key to find the best results for each user's taste.

To solve that problem Tesla recently introduced a Supercharger idle fee https://www.tesla.com/blog/improving-supercharger-availabili...

I don't agree. Planck (https://github.com/mfikes/planck) is quick and great for command line utilities written in ClojureScript. It runs on macOS' built-in JavaScriptCore. There's also an alpha version that runs on Ubuntu.

Please check the Planck User Guide's section on Scripts http://planck-repl.org/scripts.html

And for those of us who prefer editors (vs IDEs), Proto REPL for Atom (https://github.com/jasongilman/proto-repl) is a great option to work with Clojure. I think it deserves more attention, as it can help a lot with Clojure adoption.

Bounce rate for past June was 18.75%.

As for SEO, I just got a couple of backlinks by posting about Omnimemory on some websites. I considered content marketing but I haven't actually written anything yet.

Re:Ask HN: Single Person startup/company? on Sunday July 10, 2016 @02:40PM (#12066644)
I started https://omnimemory.com nearly 1 year ago. It's a spaced repetition flashcard system with a minimalist UI designed for both desktop and mobile.

It has a freemium model. It only has 35 signed-up users and nobody is paying. I only did some "marketing" for a couple of weekends (this is a side project), posting about it in some blogs, forums, Hacker News... I quickly got tired of this marketing work and moved on to other projects.

Re:Email Apps Suck on Thursday July 07, 2016 @01:05PM (#12050635)
On the other hand iOS doesn't really support the use of alternatives to the built-in Mail app. I was trying Google Inbox in a new iPad where I didn't configure the built-in Mail, but then I wanted to mail a link to a web page from Safari and I couldn't. It seems is not possible to tell iOS or Safari that I want my emails to be sent through Inbox :(

Re:Scala Native on Wednesday May 11, 2016 @05:00PM (#11679233)
That's one of the things I like about Clojure too, i.e. that is a good tool for many jobs, in part because it runs on the JVM, the browser (ClojureScript), and can also be used to build React Native apps (http://cljsrn.org/).
My idea is to keep it simple: just a collection of bots that accept any required credentials and return accounts data in a common JSON format. Storing credentials and aggregated data is not in the scope of this project. If that's needed (not all applications may need it), it has to be handled by the client app.
I'm working on BankBotsBank (https://github.com/bankbotsbank/bankbotsbank), an open effort to develop a collection of open-source bots that provide API access to accounts on any bank.

I developed the first bot, which can be used as a sample, with JavaScript (ES6, and ES7's async/await) and Nightmare (based on Electron, so on Chromium).

It's awesome because free API access to this data for any bank in the world may enable new and interesting fintech apps (actually, for me this project is a stepping stone towards another project that I plan to build on top of it), and I think that the open-source approach is the most effective way to achieve that (i.e. free and comprehensive API access to accounts data on any bank of the world).

Thanks!

Stevie Graham did that in Teller (http://teller.io/), i.e. he reverse engineered the mobile apps (https://news.ycombinator.com/item?id=11077362). But I think that controlling a browser programmatically and scraping pages is an easier approach. Sometimes it may even be the only possible one (ex. if encryption is used at the app level).

To fund roads use tolls. That's fair for all.

The money collected from the punishments can be used wherever is needed. Maybe to partially fund the roads, thus benefiting users of roads with lower tolls. Maybe to support free health and education, thus benefiting everyone.
