Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

24 XNO for Simple JavaScript Nano Payment Gateway Idea
This touches on payment ids which is historically a sore spot with Nano. Without running a full node and using unique receiving addresses, verifying payments is hard to do. That said, there are work arounds. You can leverage the NanoCrawler apis and check pending blocks for unique transaction amounts (add tx id at end of raw transaction amount). In fact thats how Nano.to is verifying payments in the backend (unless he started up his own node).

General Info and Daily Discussion
https://nanocrawler.cc/ no transactions is occurring.
-
What is the point in allowing transactions below 0,0001 Nano ? They are totally pointless in real world terms and use a enormous part of the nodes resources
Ok, then, look at the network. Transactions donβt match market-cap price. If XNO was truly $2.82 you would see much bigger transactions on the network. Recent transactions are almost always x10-3 https://nanocrawler.cc/

Nano mining to wallet was fine for months now past two days it isn't working at all.
Look up the public address you have on 2miners on nanocrawler.cc or a similar site. It most probably it says the transactions are ready to be received.

What are your biggest concerns/doubts with Nano? Only one rule: no market value discussion
I personally think the best project in crypto for money use( ideology ) is Nano but the used of nano right now is so small (https://nanocrawler.cc ) we average less than 1 tx/s of use . So we are a big community but nobody use the network.
- Solana usage, transactions per second vs other L1s
- Hey Guys. I am doing a personal project in which I pay you in Nano in return for following my Medium account. This whole process is automated and I am just conducting this project to make sure my code is running well on a large scale. If you are looking for some free Nano coin, feel free to try this

Where's the Transaction ID?
You can find the tx hash on https://nanolooker.com/ or https://nanocrawler.cc/.

Nano.to is pretty stable now. We're opening up the API for everyone. I can't wait to see what gets built with it. Skip to the end for a sneak peak of what's next from me.
That being said please remember to give credit to NanoCrawler and the wonderful APIs they made

Offline signing with atto-safesign: How to store Nano safely long term
Receiving funds while your seed is safe and offline is easy: You can just generate some addresses from your seed while on the offline machine and hand them out as usual. You can see what people are sending to these addresses by watching them at services like https://nanocrawler.cc. It starts to become more difficult once you want to pocket your funds, set your representative or withdraw funds. This is where offline signing comes into play.

eslint-plugin-big-number-rules: Enforce finance-safe calculations (helps 0.1 + 0.2 really equal 0.3)
If you use floating-points for currency (instead of whole-numbers like you probably should) libraries like bignumber.js help keep your code away from the binary floating-point pitfalls of IEEE-754 which manifests in the standard JavaScript number type:
-
Solving the "floating point precision" problem with... floats?
This issue (well, another one in a widely used JS library) is what brought me to dig deeper into these "arbitrary precision" libraries and understand why this happens. I thought they were using rational numbers, but that's not the case. And this is what led me to think about how to solve this problem.

Web 3.0 frontend stacks in 2023
ERC20 has decimals fields and must be handled with digit awareness. I wanted to use only one library, but I used both ether.js's BigNumber and bignumber.js (for display purpose).

Handling currency values: facts and best practices
Most programming languages ( JavaScript, PHP, Go, Python, Java, C# ) have built-in support or 3rd-party libraries for handling this data type, even though the internal implementations can differ:
- BigDecimal equivalent. What do you use?

[AskJS] Are there numeric textbox widgets with built-in support for big numbers like decimal.js?
I'm working on a project where users will enter numbers like 9,999,999,999.99999 (up to 15 digits, up to 5 of them decimal) and we are having a problem with Numbers losing precision beyond certain number of digits (a typical issue for IEEE Standard 754 Floating Point Numbers, the 0.1 + 0.2 problem). I've solved this problem in a few projects before with the help of decimal.js or bignumber,js . In those cases, we kept user-input as strings and used a few custom-made numeric textbox widgets to accommodate this. Unfortunately, those widgets were proprietary... Now I need one again, but can't find anything. Do they exist?

Speeding up the JavaScript ecosystem - one library at a time
Either avoid floating-point, perhaps using BigInt, or use a library like BigNumber.js. (Incidentally, I wrote an eslint plugin to enforce its use.)

Best way to deal with excessive decimal results in calculator
To solve the problem while JavaScript waits on its own BigDecimal API, you can use something like bignumber.js to perform your calculations.

How can i prove that 0.1 + 0.2 = 0.3 is there like a function or ANYTHING i can do to bypass this error which occurs in most programming languages
You need to use something like BigNumber.js
