Show HN: Tiny:optional – a C++ optional that does not waste memory
https://github.com/Sedeniono/tiny-optional
tiny::optional is a header-only C++ library for x86/x64 intended to be a drop-in replacement for std::optional with the twist that it does not require additional memory for bools, floats, doubles and raw pointers. For example, a standard optional double has twice the size of a raw double because of 7 padding bytes after the internal bool. These wasted bytes can have a notable impact on performance in memory bound applications. On the other hand, a tiny::optional double has the size of a double by exploiting unused bit patterns.

For other types such as integers, it allows to specify a "sentinel" value that represents the empty state, again causing the optional to have the same size as the underlying type.

Why Twitter favorites suck.
http://blog.sntmnt.com/post/41937834684/why-twitter-favorites-suck
I believe Twitter Favorites suck. They present a two-sided problem. I save favorites all the time, but I never check them in hindsight because there's no easy way to push them elsewhere. In addition, as I favorited a link instead of re-tweeting it, others can't see it either. So in the end, nobody wins with favoriting.

Data Is The Most Valuable Commodity On Earth

Commodities, such as oil, gold and soybeans, are tangible, real, transportable and tradeable and have been used a means of doing business, hedging risk, investing and even speculating for hundreds of years. Recently though, traditional commodities have experienced lackluster returns for investors whereas a new, non-tangible and only virtually transportable commodity has soared in popularity: data.

Offer HN: Will answer questions about UX and product design 
Inspired by those who gave back to HN, I've decided to answer all questions about user experience and product design over the next 24 hours. You can ask anything, but the more specific the better.

I come from a pure engineering background, and found my way into user experience through curiosity, passion, doing a graduate degree in Human Computer Interaction, and working as PM in a large organization (still recovering from that last one).

I've worked with over 13 startups over the past couple of years to [re]design their products. The list includes DocVerse (acquired), UStream, Delve Networks (acquired), blist, and several others.

I am currently working on my own product, but I do miss helping others with their design challenges.

Email me your questions at amir.khella@gmail.com and I will do my best to answer them in a timely manner. If I don't know the answer, I probably know someone who does. It will be a good education for both of us.

Happy Turkey Day everyone!

- Sales orders import/export

Backlog:

- Product listings
- Variations

Are there any guides that can help add some predictability around this / help with resource planning?

If you have any fun ideas on analyzing these lyrics, I am all ears.

Top 5 Features of Android 4.1 Jelly Bean
http://techcrunch.com/2012/06/27/these-are-the-top-five-features-of-android-4-1-jelly-bean/
Usefulness Rating based on * - *

GOOGLE NOW

Google Now is a sort of unifying service that takes everything the smartphone knows about the user, and everything the user’s previously wanted to know, and combines it to keep everything on track automatically.

KEYBOARD

The new Jelly Bean keyboard lets you get started by typing a word or two, and then based on what you’ve said, Android makes a few educated guesses on what your next word will be and offers them up as options before you’ve even started typing the next few words.

NOTIFICATIONS

Essentially, actions can now be performed from straight within the drop-down notifications menu. So, if you’ve missed a call, you can text or call back that contact directly from the notification widget. The same holds true for liking or commenting on foursquare check-ins and other social media interactions.

ANDROID BEAM

Android Beam now lets you tap your phone to any other NFC-enabled Android Beam phone to share photos and videos. You can also automatically pair any NFC-capable Bluetooth device, including speakers, headsets, etc., with your phone by simply tapping the phone against the device. “It’s that easy.”

CAMERA

The Jelly Bean camera app now lets users swipe for a quick preview of the last photo taken, but picture review gets even better. Users can continue swiping to see all photos taken, and pinch to shrink the gallery into a film strip UI, allowing users to navigate to the right image quickly.

You can swipe a particular picture from the film strip away to delete it, but in case it was a finger spasm or some other sort of misstep, you can always hit undo to get the image out of the trash can.

Show HN: WebReducer: build self-contained HTTP endpoints with state in seconds
https://webreducer.dev
Hey everyone,

WebReducer is a project I've been working on since last December. You can read about my process here: https://offbyone.us/tags/micro-business/

Send some data to WebReducer. Then, write a reducer function to retain some state. You can change the reducer function as much as you want and recreate that state.

Still working on how to explain it. It's a tiny FaaS platform. It's a tiny database. It's "redux" on the server as a service. It's a backend for tiny personal projects. It's a place to send your webhooks.

I'm looking for feedback on the following:

- Do you get what it is?

- What would you use it for?

- What would I need to iron out for you to seriously consider trying this?
Show HN: Starsling, a social goal-tracking site. Applying for YCS12
http://starsling.com/
Just wanted to tell everyone about our idea that we submitted.

We want to remain transparent in our process.

We have noticed a lot of people becoming interested in the quantified self with the release of such devices as the Jawbone UP, Nike Fuel Band, and the FitBit. We think there can be a better network for all of the people that currently use those devices and also people who want to manually track their progress.

Starsling will be a social goal tracking site where you can see how your friends are doing on their goals, give them motivation, and challenge or join your friends in their goals. Create goals such as Meditate 7 times a week, or read 48 books in a year. Starsling will also allow you to track your goals with or without the aid of such monitoring devices like the Jawbone UP and display your data in a helpful way.

If you have any feedback or thoughts please let us know!

Waveguides make quantum computers more reliable
http://arstechnica.com/science/news/2010/12/waveguides-make-quantum-computers-more-reliable.ars
Quantum computing is one of the current big things in both physics and computer science circles. But there is a serious divide between what we think might be possible and what we can, in fact, do. There are theorists out there working themselves into a frenzy, trying to show that quantum computing will make a smoother latte. On the experimental side, many researchers are still in various stages of single gate operations. It is like the difference between trying to make a valve and knowing what you can do with lots of valves once you have them.
