Thanks Wesleyh! It looks great.

What I notice at start is the black bar at the bottom. It's not well designed like the rest of the screen. (black and white)

The second thing is; "Downloading blockchain.."
I want to see how much I already have downloaded so I can estimate how much I still have to wait.

It would be better if you can manage to add Estimate download time, or '5 minutes left' to download the blockchain.. Something like that.
Because now I don't know if I really downloading. Maybe it's stuck somewhere at a block.

Yes, black bar will be redesigned. Or removed.

About blockchain downloading, I don't think there is a way to know how long to go still. I guess I could compare last block to current time though, and do an approximation based on 1 block per minute?

And blocks do not update live in the window, need to go to other menu and then back to "Blocks"

They should update on the main screen, but it takes some time, api is slower to show new blocks.

FreeRider beta0.1 released:





git clone https://github.com/l8orre/FreeRider

cd FreeRider

./nxtFreeRider.py


Also available at:

https://www.quicknxt.com/FreeRider





I believe that nxtFreeRider will make a valuable and distinct contribution to the nxt clients ecosystem.

Features/Attributes:

- python3/PyQt4: fully open source, code inspection extremely easy rapid development/modification possible by anybody,
- script language: no binary that must either be trusted or compiled from source
- developer tool: includes api access window for testing, new api calls can be added very fast
- using QThreadpool, query threads can be used for NRS backend load testing
- Focus on Asset Exchange
- python provides scipy: scipy has become the single most powerful and versatile scientific computation environment available
- can be used as a tool to analyse node behaviour and counteract malicious attacks on the network.

The availability of scipy provides a unique feature that no other client has - I have the impression that this aspect is a bit underrated so far.

If you´ve read my PM, I am trying to help you build a core dev team...

Yes, I need to think about how this should be done. Before the source was public, the problem was how to decide who is trustworthy. Now that it is open, how do we decide who is good enough?

Companies conduct technical interviews. Those will filter out the completely ignorant, but for more experienced people it becomes difficult to judge who is better. I am also not confident in my own skills as an interviewer, and also some good people perform bad at interviews because of the stress and pressure to perform. Especially for an open source project, I don't feel doing interviews is the right approach.

For paid developers, we could consider trial projects, which they would do on their own fork of the repository, and if at the end we like the code and integrate it into the main repository, we accept them as paid developers. This would mean they would have to spend a few weeks without pay at first. Or, we can take the risk and do it as a one month paid contract, with the option of making it permanent. This would be something the NXTtechdevfund committee should discuss.

I would need to research how other open source projects decide who to accept and trust, e.g. how the linux kernel development is organized, and see if we can adopt their project management practices.

In terms of skill set, being a very good Java developer is the only requirement. The code does not depend strongly on any specific tool or library. We use a database, so some familiarity with relational database and SQL is needed, but there are enough areas of the code one can work on without touching the database at first. We also use servlets and Jetty, so again familiarity with servlets and the http protocol would be helpful, but most Java developers already have that.

Good object-oriented design skills are essential. So is writing clean and maintainable code. For developers with main background in languages other than Java, I can tell immediately that Java is not their native language - I have seen lots of Java code that reads like C. The original BCNext code was very foreign too, so I had to rewrite lots of it. So for somebody coming from C/C++ background, if this is going to be their first Java project, they would need to learn a lot, so that the code they add actually reads like Java.

In addition to Java developers, and in fact much more urgently, we need a good cryptographer. This person doesn't even need to be that fluent in Java, the language background wouldn't matter (well, he should at least be able to read and understand the Java code). But I don't have much cryptography background myself, so this is an area where we currently lack skills, especially after the departure of BCNext.


Jean Luc, I want to thank you for this.
It helps to know that we are looking for good people to get on board for the future development.
It also helps to know that you will be staying on board so there is no knowledge leak.

And thanks to mcjavar for organising this!

Thank you very much for your detailed answer!

"For paid developers, we could consider trial projects, which they would do on their own fork of the repository, and if at the end we like the code and integrate it into the main repository, we accept them as paid developers. This would mean they would have to spend a few weeks without pay at first. Or, we can take the risk and do it as a one month paid contract, with the option of making it permanent.

Give the applicant a real life scenario to work on. Something that has to be done for Nxt. A small part of a bigger task. So you can assess if he/she is good enough to be in the core dev team.

"In addition to Java developers, and in fact much more urgently, we need a good cryptographer."

Is that the same msin is working on with the review of the code? Or we need a cryptographer in our core dev team? Do you (or anyone else) have a suggestion whom we should approach?


I would be happy to come up with test Java projects for someone else to do Smiley

I could pay some amount of NXT upfront to reduce the risk for the new applicant, as long as we have reason to believe that he can do the job. Then I will need the Techcommittee to deal with any permanent arrangements and completion bounties.

Probably a good idea to have a good cryptographer on retainer or at least halftime. If the community can provide adequate testing, then that frees up more funds to pay the cryptographer. I dont think it has to be a big name guy, as long as he can do the crypto math competently, that is the key. Someone who can actually understand stuff like https://bitcointalk.org/index.php?topic=277389.0

I can help with completion time estimate algos. I will PM you

Yes.

Cool. You should add some kind of random password generator for creating new accounts, and then it should be distributed with all new NRS releases as a default client

Not sure if there is a good and secure javascript.random available - However if you open the app and choose register new account, (new users will probably do this although they could just login), then it requires special characters, minimum length, etc.

I have also sent the html interface to jean-luc, hopefully it will be in the next version (it is in this NxtWallet.exe already)
I will not have time to make another release until Sunday at best. For now, people should install Wesley's client manually.

It doesn't need to be perfect. An estimate is fine by me!

First of all, Keep up with the great work!

I'm a newbie here but I would like to give you my two cents...
I believe that NXT has all the potential to become the next big thing. I see a great idea and I see great people working on it. I see also a great community that is forming around it.
The only problem is that for new people like me is very difficult to follow and join. There is this huge megathread that is growing faster than my reading capabilites. In this thread there is everything: from technical development discussions, to new software announcements, newbie opinions, complaints, philosophical discussions and everything else...
This is great, but frankly speaking, is not optimal. It end up that people just trow in it their opinion but without listening really at what other are saying.

My practical proposal: why not to split this thread in different threads? One for the technical/developers, one for the marketing, one for the newbie, etc.?

Or maybe there are already some different channels? (in this case, please point out where)
Cheers

You can use random mouse movement to create pretty secure password.

Or like Bitcoin wallets with a green bar that shows the progress of downloading the blockchain.

Thanks!

Don't get offended or something. I'm just being a critical end user. Great work!

Not offended at all, I need and appreciate the feedback Smiley
