New Exotic Material Could Revolutionize Electronics
http://www.sciencedaily.com/releases/2009/06/090615144431.htm
ScienceDaily (June 16, 2009) — Move over, silicon—it may be time to give the Valley a new name. Physicists at the Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have confirmed the existence of a type of material that could one day provide dramatically faster, more efficient computer chips.
Ask HN: Why isn't email spam solved using Proof of Work yet?
Why not solve spam emails by letting senders work on some cryptographic puzzle (e.g. Proof of Work) that recipients can verify. This would prohibit spammers from sending massive amounts of email, since the required proof of work would scale linearly with the number of recipients.

For example let the sender search for a hash that must satisfy following condition: hash(recipient-email-address+message-content+nonce) % 42 == 0

If the hash does not match this condition, proof of work is missing and the email likely spam.

Another parameter could be the amount of work done by choosing different hash functions or hash functions that have parameters that tweak their run time.
Ask HN: LinkedIn made me reset my password (my email was in the Gawker dump)
I suspect LinkedIn is checking email addresses against the hacked Gawker data and forcing any matching accounts to reset their password. Here's an except of the email they sent me:

In order to ensure that you continue to have the best experience using
LinkedIn, we are constantly monitoring our site to make sure your account information is safe.

We have recently disabled your account for security reasons.

Is this happening to anyone else? for other sites?
Ask HN: Where might a fundamental rethink of operating systems lead?
Imagine everything we know about operating systems was tossed out the window.

An entirely clean slate approach to rethinking how operating systems and software should work.

Does that concept make sense at any level? What might come out of such an exercise?

Is it even possible to make a dramatic innovation given that we already have such strong ideas in our heads about how operating systems work? Perhaps it's not possible to imagine things dramatically differently from what we have already experienced.

Ask HN: Review my startup, Beansight.com
Hi Everyone,

One of my friend told me that I can get great feedbacks with Ask HN to improve my startups. So let's ask you.

I'am working working on a new website where people can share predictions and be rewarded for good ones.

On Beansight you can share and record your predictions about what it’s going to happen. You can also read other members predictions and agree or disagree with them. Most important, you can also write comments to argue your position.

If members make good predictions, they will earn credibility points and if they earn a lot of them, they will become an expert on Beansight. So they will be able to use their Beansight profile to prove their expertise.

We're planning on launching a lot of new features in the coming months, but we've gotten to a point where we'd really appreciate some feedback for improving effect. We are particularly looking for feedback about the UI.

Thank you

Cyril

Tell HN: Every YC Interview Experience Ever Discussed On HN
A couple hours and 99 pages later of Google search results for "interview site:news.ycombinator.com", I have a database of all 25 blog entries of YC interviews ever discussed on Hacker News. Here they are:
http://ycuniverse.com/interviewees.php

(I'm a YC funded startup founder with a ton of ideas and little time for side projects... so rather than file ideas way in notebooks... I'm posting them online and giving them away. Some are small app ideas, some full on "startup" ideas and some fall somewhere else in the creative landscape. No need to steal these ideas, I'm giving you permission to take them. Good luck!)

Ask HN: Economics community website?
I feel that there is a need for a news and discussion site with opinion on economics and business. "New Mogul" has been down for a while now or for good, it used to be a place where people that like economics could discuss the major issues. Are there similar sites out there that anyone visits?

I read The Economist and Zero Hedge routinely, and Seeking Alpha, Forbes etc occasionally. Still, I'd be interested in starting a community focused on the above if others would be interested too.

My email's in my profile if you want to discuss privately.

Microsoft's Hottest New Profit Center: Android
http://www.networkworld.com/news/2011/070511-microsoft-patent-android.html?hpg1=bn
One of Microsoft's hottest new profit centers is a smartphone platform you've definitely heard of: Android. Google's Linux-based mobile operating system is a favorite target for Microsoft's patent attorneys, who are suing numerous Android vendors and just today announced that another manufacturer has agreed to write checks to Microsoft every time it ships an Android device. Vendors paying off Microsoft for the right to use Android now include HTC, Velocity Micro, General Dynamics, Onkyo Corp. and Wistron. Microsoft likely makes more money from Android than its own Windows phone platform, and its latest patent agreement announced Tuesday indicates Microsoft is also going after Google's Linux-based Chromebooks.

Ask HN: Your tips/hacks for great academic writing
This is a little bit of a follow-on from a recent post about hired writers for various educational essays. Link: http://news.ycombinator.com/item?id=1901152

And no, cheating is not an option.
Markdown-based notepad
https://wri.pe/
It started from my personal problem, "I want to take memos using markdown!"
I use a memo app everyday. I used Evernote, but it's too big for writing memo.

I thought "I'm a programmer, so I can create a memo app easily!"
I started to create a memo app with the following features.

- markdown format
- gmail like Archive feature
- Calendar view
- iPhone/iPad support
- keyboard shortcuts

I thought some people could have same problem when I was creating it.
So I decide to release it to public.

Today, I released my tool "https://wri.pe".
Especially, Tech people would love it!

Screenshots are here.

Feedback on how to improve it is also very welcome.

I hope you love https://wri.pe .
Show HN: Stable Diffusion print-on-demand apparel
https://www.1sewn.com/
Hey HN,

Obviously we are experiencing a surge of stable-diffusion based apps at the moment, but I have yet to see anyone try and map the outputs onto actual physical products that can be delivered to your door.

I wanted to make it easy to:

- pick an artistic style

- hit 'record' and speak into your phone / tablet / desktop or whatever, and describe the kind of design you want your clothing to have (since speaking is more spontaneous that typing)

- swipe among a variety of mockups (t-shirts, hoodies etc.) featuring your design, and order it to your door with the click of a button

The product is called 1SEWN. Fulfilment is currently achieved using a print-on-demand service called Printful (https://www.printful.com) that I have integrated with.

If you guys would like to try it, I would love some feedback. Shipping is currently limited to outside Europe, but even if you are in Europe, your feedback about the whole UX would be much appreciated!

Much love,

Matt

Show HN: I am building a free version of Strava
https://mtbx.bike?page=hangtime
I recently added a Segments feature to the Hangtime mountain biking app for Android and IOS. If you are familiar with Strava’s segments, this new feature works much the same. For example, you can add a segment to an existing recorded ride by simply defining a start and end point for the segment. Once the segment is created, it will match any new rides, and optionally “back match” all previous rides. If a segment matches a ride, you you will see your time to complete that segment as well as your personal record (PR) and king of the mountain (KOM) for that segment. The KOM represents the best segment time amongst all riders that have matched that segment. You can also open the segment to see your complete history on that segment to gauge how your performance has changed over time. Some screenshots and videos as well as other features at the link below.

Game Changing Android Application
http://www.enkin.net/
If Android manages to clear the porting obstacles that await it as it's distributed over more than one reference device, and if it manages to deliver a high bar of quality (at least as high as the SDK has shown so far), it could really change the way we live/work. Those are some big ifs ... but some exciting ones nonetheless.

Google Said to Be in Talks to Acquire Travel Software Maker ITA

If GOOG buys them, will they force a rewrite in Python? I'm under the impression that ITA funds a lot of development/creation of tools for Common Lisp, so what impact might that have on the Lisp ecosystem?

Tell HN: Doing a PhD is good
Or having a higher education. A general trend here is to discard PhD/higher education as a waste of time or money when one want to go the startup way. Effectively, you can become rich without such education, but very few of them get really rich and on the barrier to entry, if you consider a field where you can be disruptive without education is rather low.

The real good point of having a PhD is not in the title you get, it is in the network you can build and the problems you try to solve. By definition, most of the scientific PhD are to solve industrial problems. This means, you have a complex problem and customers, directly, right now, during your studies.

If you are smart, you can already have a portfolio of customers at the end of your PhD, you can have your product nearly ready and you will be able to charge your customers more in thousands of Dollars than in $9 per month.

Bonus point, the barrier to entry will be high for the competition and it is relatively easy to become an expert in your field.

So please, if you want to do a PhD, do it and do it wisely.

A short list to think about:

1. Get a supervisor known to give his students a lot of freedom.
2. Do your PhD in a country where you get a good pay (most of the EU countries pay well for a PhD).
3. Go in a university with a good budget for travel to conferences.
4. Find labs with intensive industrial collaboration.

Show HN: Pipedream 2.0 – AWS Lambda + Zapier alternative
https://pipedream.com/
Hey HN! Pipedream is an integration and compute platform purpose-built for developers building workflows and connecting cloud services.

You can author workflows without writing any code: Pipedream supports over 700 integrated applications (GitHub, Slack, etc) [1] and all connectors are open source [2]. In addition, you can write any Node.js, Python, Go, or Bash code within workflows, extending the pre-built integrations with your own custom logic.

Since we launched Pipedream on HN [3], over 300k developers have used the product. Pipedream developers tell us consistently that they love the code-level control when they need it, and the built-in, no code integrations when they don't. But we’ve also heard consistent feedback that the product needed to be easier to use, support more language runtimes, and provide a native Git integration.

In Pipedream v2, we have re-imagined the entire product and key features, including:

- Multi-language support including Node, Python, Golang, and Bash
- Data Stores to store and retrieve data across steps & workflows
- Open source triggers and actions for 700+ applications
- Improved workflow builder to test and iterate without impacting live workflows
- Multiple triggers are now supported per workflow
- Improved forms and testing for rapid step-by-step development

We’re working on a GitHub integration now, which will let you manage workflow definitions as code. You can still use the Pipedream UI to author workflows, and use Pipedream’s pre-built integration components to build integrations, but you’ll be able to serialize those workflows to code. Think Terraform or CDK for app integrations. You can sign up for our waitlist below. [4]

My cofounder @dylburger and I will be here to answer any questions.

Show HN: Find the 10 highest and 10 lowest correlations to any stock
https://betagainst.fun/
During the start of the year I was thinking how could I bet against certain stocks (in my case mainly Tesla) without using derivatives and the risks that come with them.

After I had success betting on the oil price with a highly correlated investment fond, I came to the conclusion that negative correlations could be used to bet against the price of other assets. Unfortunately, it is not easy to find correlations between assets if you don't know which assets to compare in the first place.

So I created a website where you can find the 10 highest and 10 lowest correlations of certain assets.
