Ask HN: Making a proposal to finance startup
I was requested by a finance startup to find a group of stocks in order to get yearly(2006-2014) return and risk to a desired level(minimum return -5%, avg return 10%).

I have been reading about it and I think "Modern Portfolio Theory" is related to this and Convex Optimization is being used to find the best solution. The problem is I have no idea if this is a difficult task or there are a lot of already available open source solutions to the problem given.

And that's my problem, because it's a topic I know almost nothing, I can't tell the startup how much the solution is going to cost. I'm thinking about offering this options:

1- Monthly fee(3 months) and if by the end of the period I find an acceptable solution(defined before start) I get a cash bonus.

2- Only receive a payment if I find an acceptable solution(much more high amount than 1).

3- Some other interesting proposal.

What do you think?, how do you handle this type of cases where you don't have previous experience?.

Edit: I'd like to mention that I have other clients so I can live without charging to this one for a while and I can tolerate some amount of risk in this project.
Show HN: BudgetBuddy a new way to track spending
https://www.budgetbud.xyz
Budget Buddy is a spending tracker that lives in your messaging app. I built this tool because I'd often download budget apps and forget or just not use their features. This application, to me, makes recording my spending easy.

This is my first project out of college and I learned a lot about hosting, CI and docker.

I would love some feedback on the code and the tool itself. The code can be found here: https://github.com/zlederman/budgetBuddy.
Ask HN: Proliferation of Big Data Tools
There's a proliferation of big data tools out there (Flink, Kafka, Spark, Storm, Hadoop, RedShift, Athena, BigQuery, etc) and it's a overwhelming trying to understand what niche they're all trying to fill in the space.

Was wondering if there are any resources that help break down the domain and which tools are appropriate for solving specific problems.

There's a ton of articles comparing a few of the technologies against each other, but I'm looking for something a bit more structured and in-depth.

Ask HN: Possible to build enhanced SMTP?
Just curious since there are not many new net protocol being establish lately since SMTP, NNTP, HTTP etc. Seems like most work in last many years is concentrated on enhancing HTTP.

Why not an enhanced SMTP protocol that is compatible with SMTP, but with realtime capability for a unified text based messaging platform that replaces email, chat and sms/mms?

Baseball player says it's harder to hit than to learn to do algorithms
http://www.washingtonpost.com/sports/nationals/for-washington-nationals-jayson-werth-hitting-is-a-journey-without-end/2014/03/18/8958cc1c-aebf-11e3-a49e-76adc9210f19_story.html?tid=hpModule_c7c1f590-868f-11e2-9d71-f0feafdd1394
Here's the full quote from Jason Werth

“Because it doesn’t work both ways,” Werth said. “Just because you can do something else doesn’t mean you can hit. If you can hit, you can do anything. Because it’s the hardest thing to do. There’s nothing harder. I can bake a cake. I could figure out a way to do algorithms. But a guy that knows how to do algorithms could never hit. It’s literally the hardest thing to do. If you can do the hardest thing, you can do anything else.”

Ask HN: How to jumpstart a new social platform
Hey HN,

So I've been toiling away at creating a new social platform for TV (https://couchmate.com). I'm running into the classic chicken/egg problem at trying to get users simply aware that I exist. I'm looking for options from the HN crowd at things I might be overlooking.

(1) Paid Ads. I'm bootstrapping, so my budget is paltry. Ran ads on Facebook, Insta, Twitter and Reddit. Didn't really drive any traffic to the site/downloads. I'm also creating all the creatives myself (Photoshop, After Effects, etc) so this is a huge time sink.

(2) Social. I have social media accounts on every platform as well as a blog that I try to post to at a somewhat regular interval but again, that's a huge time sink to coordinate between all the services, post relevant things, etc.

(3) Word of Mouth. Obviously trying to work my network and spread the word that way. So far it's been the most lucrative but also very slow.

(4) Direct Contact. I've been trying to walk the line between spam and genuine contact with other people online. I haven't gone so far as to automate DM/PMs to people for feedback but I've posted on various subreddits (and Show HN) for feedback that hasn't born much fruit.

(5) Influencers. Been looking down this path on how to create a mutually beneficial relationship between influencers (specifically podcasters) and my platform. This is a work in progress but could work if they see benefit for their audience as well.

Again, budget is tiny and time is precious. I feel like I've been putting engineering principals to marketing and it's been not super successful. I'm an engineer by trade so there's a learning curve in how to take these on individually. Also I have tried to reach out to people to actually come on board and do marketing but haven't really found any takers yet.

Radial accelerator
https://github.com/singularian/radialaccelerator
The recent chip accelerator is a linear accelerator. It looks like they used a linear channel for the chip. I believe this view of accelerators is incorrect and accelerators need to use a looping radial channel which would allow for 1000 kilometer or more accelerators. a centimeter array could contain a 50 meter accelerator.
A linear accelerator is inefficient relative to a looped structure.
