ARM based processors coming to Linux netbooks
http://arstechnica.com/journals/linux.ars/2009/01/07/new-freescale-processors-target-linux-netbooks
Freescale's ARM based i.MX515 will have the capability to power machines with up to 8 hours of battery life, with a display as large as 8.9 inches. Sporting an ARM Cortex-A8 core, the chip performs from around 600mHz to 1 GHz.

Seems like a clash between Intel and ARM is imminent.

Ask HN:  What logical fallacies irritate you the most on Hacker News?
One I find annoying is when someone gives a counterexample as if that would be enough to shoot down an (implicitly) statistical claim/argument.
I just discovered an overwhelming competitor
Hello all,
I am a web developer, have been working on a project of mine for several months now. I am working on it as a hobby, putting my free time at the end of every day and in weekends (I cannot find more time, as I cannot quit my day job).
I’ve preformed a very comprehensive market research to make sure my idea is unique. A few weeks ago a competitor launched an application almost identical to mine, but much better. It was built by a small startup, with the investment of a venture capital. They currently have 4 workers working full time on the project.
For comparison, my application doesn’t reach half the level of what they’ve built and only now am I about to launch my application to the open public. I currently have no users but friends who are giving me usability feedback.
The market in which we are both working is huge, and currently we are the only two players in it.

What should I do?

Thank you
Show HN: Equities.fyi – Startup valuations based on public company data
https://equities.fyi/company/stripe
With the current down markets, we were wondering what private company valuations looked like when compared to similar public companies. We were inspired by the a16z article (https://future.com/framework-valuation-navigating-down-marke...) for calculating valuations and figured out the sales-to-valuation ratio of public companies at the time of the last fundraising round and applied the change in the public market to get the current startup valuation.

If things don’t look right, our defaults might be off - please feel free to change those if they’re too different from what you’d expect.

Ask HN: Would you read lessons walking through every step of a hardware startup?
I keep hearing talk about an upcoming "internet of things" and yet I see very few startups building physical products. It's no surprise though! Commercial scale production of hardware is a dark art; a unpredictable and archaic process passed down to new apprentices via direct contact.

So I want to create a site to publish (and link to) content that would teach: soldering, rework, pcb cad, assembly, plastics, textiles, packaging, production in asia, contract manufacturers, QA, import laws, selling B&M, IP concerns, etc. Furthermore I would like more technical articles giving accessible landscape views of microprocessors, wireless solutions, sensors, LCDs, etc.

Everything you would need to build and sell hardware on a commercial scale, really.

Would you read this? What topics would be most interesting?

Ask HN:Patent Unwillingness
A friend of mine who is currently perusing his Master currently mentioned to me that, the Idea he submitted for his project has impressed his professors and the college is applying a patent on the idea.He was not completely willing to patent it,the reason being the compromise of the idea and a openness in sharing the idea. Today he received the news that the patent is shared with 2 other top level profs who have not helped him in any way. He is pissed now and wants to back out. What does HN say what is a wise decision in such a case?

Meet PastPages.org, the news homepage archive. (And help keep it alive)
http://www.pastpages.org/
I cre­ated this site be­cause I think it ought to ex­ist. The shift­ing homepages of ma­jor me­dia sites should be saved so they can be stud­ied. Done right, I be­lieve Pas­t­Pages could serve as a re­source for schol­ars seek­ing to study cov­er­age of news events, like the up­com­ing U.S. pres­id­en­tial elec­tion.

Regularly collecting the data costs money. So I've organized a Kickstarter in hopes of raising funds to keep it up. http://www.kickstarter.com/projects/651552740/keep-pastpages-alive
Ask HN: I have a startup idea, the project is 90% done. But..
Hi everyone! I'm malaysian. Going to gradute in CS soon. Currently I'm working alone on my own web project in purpose to run a startup right after I've finish my last day in CS faculty or maybe before the last day.

But the problem is, I always doubt at my own ideas and potential to execute the idea. Yes, I'm ready to take any risks but at some times, severally, I feel unmotivated, uninspired any more because of my surroundings and friends network are not really into realistic interest in entrepreneurship.

Any positive constructive advice on how to overcome these emotional obstacles, how to manage poisonous unmotivated people around and how to stay persist on what I believe will work.

That's all. Thank you.
Show HN: QABounty – Make money answering questions
https://qabounty.com/
I recently finished my site QABounty.

I would get annoyed when I could not get anyone to answer my questions on sites like Stack Overflow so I created this site, https://qabounty.com/. It is basically your standard QA site but you attach a USD $$ bounty to questions. For example I have a question up at:

https://qabounty.com/questions/what-kind-of-database-should-i-use-when-trying-to-store-10-to-15-million-rows-a-day/

The best answer for that question will award that user 3 coins (which can be withdrawn for about $3). I plan on adding my own questions of the day for a while, basically giving money away for a while hoping people use it for their own questions eventually. If you want to make a quick $3 though and check out my idea please go to the site and try to answer the question!

Let me know what you think! I am also looking for a designer as well after I see if people like the idea.. I used Stripe's new withdraw to debit card feature so you don't have to use bank account info to withdraw your "bounty" (money you get for answering questions)... Please give me some feedback on the site/idea!

Show HN: Open-source infra for building embedded data pipelines
https://github.com/pipebird/pipebird
Hey HN!

We are building *open source infrastructure for deploying customer-facing data pipelines.*

Here’s our repo https://github.com/pipebird/pipebird and website https://pipebird.com/.

Pipebird (YC W22) is designed to enable companies that generate important data to offer secure data pushes to their customers’ warehouses, directly from their products.

Our team was previously building in fintech, where we heard from many of our peers that their customers wanted data pushed directly to their warehouses. Customers wanted to bring data into their source of truth without having to maintain custom built pipelines or introduce security risks by contracting a third-party ETL/ELT provider.

After seeing Stripe https://stripe.com/data-pipeline and customer.io https://customer.io/data-warehouse recently invest in building out their own native data sharing products, we realized that many SaaS companies could better support their customers and even generate additional revenue by offering native data pipelines.

Our goal with Pipebird is to make creating a reliable data pipeline as simple as pressing a button from a vendor's dashboard.

With the current iteration of the product, data can be selected from a number of sources (ex: Postgres, MySQL, CockroachDB, etc.), customers can configure pipelines and optionally apply transformations (like type casting), and data can be periodically synced directly to customers’ warehouses (ex: Snowflake). We’re actively adding sources/destinations and would appreciate any feature requests.

Here's a 2 min demo of the product https://www.loom.com/share/c7a7e4b4e57c4015b533fd754c510b2e

Pipebird is open source (MIT license) so that any developer can use it. Our aim is to not charge individual developers - we make money selling paid plans that include features like multiple projects, user permissions, additional security features, managed infra, support, etc.

Give us a whirl: https://github.com/pipebird/pipebird. We’d love your feedback and will be here to answer any questions!

Show HN: Fliple - iOS Contacts with Metro UI
http://FlipleApp.com
This is my try at a iOS Contacts app replacement.
I was frustrated by the fact that the default application wasn't showing contact pictures in lists, so I tried to design an app that makes full use of the images.

Another issue I had with the default app was the number of taps until finding a contact, so I tried to minimize that too using various approaches:

- put most contacted people on the main screen (app also proposes new tiles based on number of interactions)
- group contacts (work, family, friends, etc.) then put a group tile on the main screen
- search the contact list using T9 (3-4 taps to locate contact)
- use action tiles to instantly communicate with a contact (phone, SMS, mail) for often contacted people

At the moment the app is free, I haven't yet come up with ideas for monetization - if you have any, please share.
Show HN: Prepform – AI and spaced-repetition to optimize learning
https://prepform.com
Hi, I'm Eric and I'm the founder and lead developer of Prepform.

A high-quality education helped me pursue my interests and achieve my goals. I started Prepform so students of all backgrounds have access to the same kind of education.

I grew up in Southern California, surrounded by dozens of SAT prep programs, and I swear I must have gone to all of them. Different programs followed different styles and techniques, but the strategy they shared was to create a study plan and review mistakes.

A study plan is
taking a diagnostic test,

setting a target score,

creating a study schedule,

identifying mistakes, and finally

reviewing those mistakes.

I wanted to take this structure and optimize it with machine learning, while accounting for elements of human learning and memory.
I'm a big fan of SuperMemo, a memorization technique developed by Piotr Wozniak, where you review material just as you're about to forget it. Cognitive psychology tells us human forgetting follows a pattern, but Piotr quantified this behavior to identify the precise moment forgetting happens.

The goal was to build on his research with AI and tailor it to not only test prep but to the individual student, and make it the engine of the study plan.

The result is Blended Prep, which guides students to internalize knowledge rather than memorize material, and gives them the best chance to ace their next exam.

I'm so excited to share this with the HN community, and would love to know what you think. You can try it out at https://prepform.com. Thanks for reading.
The Future is Movie OS
http://danhon.com/2010/04/16/the-future-is-movie-os/
We make fun of fictional Movie OS because it's "not realistic" (it's not), but haven't recognised that it fixes a problem we've not been dealing with adequately: creating intuitive software user experiences where actions result in transparently understood actions.

I argue that the requirements of Movie OS (that they must clearly convey critical plot information) produce clear lessons that we can learn from when we design user experiences. A dialog box with good copy and "Are you sure?" isn't good enough anymore.

Show HN: Download Twitter data without API keys
https://tweetfeast.com/
In April last year I started thinking about using Twitter in a smarter way. I wanted to do analytics on my tweets and find out more about people following me on Twitter. What kinds of things do people who follow me like and retweet? I decided to dig into the data and find out.

When I went to try and download Twitter data in raw form I found I quickly got bogged down writing API wrangling code and fiddling with API keys. I just wanted to crunch some data but here I was wrangling Twitter's API. This was such a frustrating experience it suddenly looked like an opportunity to me. Was there room for a product here? A product which does one simple thing: help people extract Twitter data painlessly without writing any code.

I did some research and discovered some tools that purported to do this, but none of them worked well for my use-case and all were badly designed and/or expensive. I decided to take a shot at it.

I worked on this as a side project in a "calm company" fashion. Each week for 26 weeks I would put aside one day to chip away at the features. I tried not to think about how the issue tracker was filling up more and more. Several times I pared back the feature set to try to really focus on the core use-case.

When my first user reached out and engaged I knew I might be onto something. I kept posting progress on Twitter and a few more people started to use it each week. Some of them came back, hinting at possible user retention. I hired a writer to write some articles to help with SEO and I kept working towards and MVP that I could use to test the market.

Finally the day arrived where all of the critical issues in my issue tracker were closed. That meant it was launch day. That was yesterday. So here I am releasing this on Hacker News to you, dear reader.

God speed little micro-SaaS, may the winds of fortune be at your back.
Show HN: Pi-hole deployed at the edge on Fly.io and accessed via TailScale
https://github.com/mtremsal/pihole-fly-tailscale
Hi, I just saw this tweet[^1] by @QuinnyPig that mentions accessing your Pi-hole while traveling thanks to TailScale and wondered how to deploy Pi-hole at the edge, instead of a home lab, for improved latency.

My simple solution involves running it on Fly.io to make it easy to relocate anywhere, and embedding tailscale into the same firecracker VM (né docker container) to keep the infra dead simple and cheap.

Naively deploying a publicly accessible DNS resolver is not ideal[^2] so the main constraint was to secure the VM by 1) keeping all public ports closed and 2) having Pi-hole listen only on the private network interface created by TailScale.

It's all very straightforward but it's noticeably improved my bandwidth usage and page loading times across my laptop and mobile phone, so I figured I'd share. Suggestions for improvement are also welcome!
