sabalaba··on Xiaomi laptop leaked online with specs
Big +1 on the Smartisan (锤子). I really like their interface. The Smartisan OS is one of the most thoughtfully and beautifully designed Android systems that I've seen.
sabalaba··on Xiaomi laptop leaked online with specs
Not really. While some of the software UI looks similar. The hardware is pretty unique. Have you ever held a Xiaomi before? I own both a Mi 2s and Mi 3; the hardware and software experience is really quite different from Apple. (And most of the rest of the Android ecosystem for that matter.) The "copycat" claims are overblown.
sabalaba··on Show HN: Smoothie, a GIF Camera that respects your privacy.
I helped write some of the first iterations of this app. This is one of the few camera apps that doesn't even have a backend server. The goal was to create a fun way to share a moment with somebody. I'd be curious to see what those on HN with an iPhone think.
sabalaba··on Google Glass future clouded as some early believers lose faith
I got Glass in April 2013. I realized that I used Google Glass to solve two problems:

1) Taking pictures and video of my day. 2) Telling the time.

The notifications features were not useful to me and being seen in public with the device on was embarrassing. I ended up deciding to make my own version of Glass (called Lambda Hat) that was more discrete and solved the first problem above and left the second to my cellphone.

sabalaba··on The poetry and brief life of a Foxconn worker: Xu Lizhi (1990-2014)
I completely agree that solutions probably don't lie within politics as usual. But, from the perspective libcom would have you adopt, we should go to "liberatarian communism". The real irony here is that libcom is trying to spread this brand of communism by highlighting a tragedy in a country that has seen the fastest rise out of poverty in the history of the world due to, ahem, free market economic reforms.
sabalaba··on The Flaw Lurking in Every Deep Neural Net
If you rephrase your question to "What happens when I add random noise to the inputs of a neural network and try to teach it to output a "denoised" version of the input." and you've just invented denoising autoencoders.

sabalaba··on Israel’s N.S.A. Scandal
Political influence arising from an active group of Jewish-Americans lobbying their own government not "ownership". If you're against it, you too are free to get involved, form a special interest group, and lobby our government in the other direction.
sabalaba··on Total Moving Face Reconstruction
3D reconstruction is used in state-of-the-art facial recognition as well.[1] Essentially you reconstruct the face in 3D, rotate the 3D model to the front, project it back into 2 dimensions, and then feed it through a CNN with deep architecture. Because this gives you very good alignment, you can do tricks like not having shared weights across the entire image. That is, each section of the input vector is known to correspond to a certain part of the face and thus can learn unique parameters that are well suited for that specific region.

The paper claims that it takes about 105 seconds to render a single frame. So one second of 30 fps video would take about 52 minutes to render. I would have to read more in depth to see what kind of savings can be had by sharing information across frames. (The paper also doesn't mention the use of GPU acceleration.)

sabalaba··on Abstract visualization of biological neural network
This doesn't look like a neural network that's solving any actual problems beyond visualizing firing patterns. Most ANNs don't have any concept of time built into the model. When you're in feed-forward mode, the underlying computation is simply a bunch of dot products.

However, you might be able to make some cool visualizations if your ANN was a Spiking Neural Network.

sabalaba··on Show HN: InvoiceAtOnce – Easy Invoice Creation
If you would rather do this using json and a command line tool: https://github.com/lambdal/envois

That's a FOSS utility I've been working on for the past two years. I use it for all of my invoices.

You can create your invoices like this:

    ./scripts/envois < scripts/invoice.json > output.html
sabalaba··on Marka: Icon transformations
It's a beautiful image free icon set with full transition animations. It's good for putting dynamic icons into sites and apps without booting up GIMP or Photoshop.
sabalaba··on First-Person Hyper-lapse Videos
This is great. I have weeks of footage from a camera that I wear around and would love to use that video to make a hyperlapse. I would also be interested in seeing how well this does with photos taken every few seconds as opposed to video. Although, after reading the paper, it looks like there would be a lot of optimization that would need to happen to make it more efficient. (Their original implementation took a few hours on a cluster.) Luckily, as they stated in the technical video, they haven't tried to do anything more than a proof of concept; so there is plenty of room to optimize. I'd be interested to see how well a single-machine OpenCL or CUDA implementation does compared to the CPU clusters they were using in the paper.
sabalaba··on IPFS: The Permanent Web
According to a report by EMC, current global storage capacity is around 1.5 zettabytes (1.5 million petabytes) [1]. With Commercial off-the-shelf hardware, storing 1 PB of data carries a fixed cost of around $100,000 USD [2]. Thus, the cost of today's storage capacity is around $150 billion USD. (About what the United States government pays every year in interest [3].) Those numbers are expected to increase an order of magnitude by 2020. Thankfully this does not apply to the interest payments.

With numbers like that, and with cloud storage prices sitting very far away from marginal costs, protocols and incentive structures like IPFS and filecoin are going to be of great value to enterprises, governments, and consumers. I would not be surprised if, by 2020, a majority portion of the data online was stored in such a system; with exponential growth, a new majority share is created every ln(2) / rate years. In the case of the "data universe", which grows about 40% annually, doubling time is about 2 years [1].

sabalaba··on Stripe: Alipay support
This is a huge deal. I'm currently in Shenzhen and Alipay (支付宝) is a common and convenient way to make payments, on Taobao, in person, or otherwise. Alipay is an interesting product in its own right, even if examined independently of the Alibaba Group. It has a money market service, Yu'E Bao (余额宝) that is currently a top 3 global money market fund with $89B AUM. That's a taste of the scale of the market in China.

sabalaba··on How can an introvert Asian engineer like me make friends?
Full Text:

(I had to use Google Docs because my text exceeded 2000 characters. I apologize.)

I know the question sounds really awkward, but it's just exactly what I think.

I am a software engineer intern at a mid-sized company in redwood city, and my internship ends on August.

I love my work, and I consider myself a reasonably intelligent, tidy, and nice guy.

However, it saddens me when I find myself idling alone on weekends, doing everything by myself.

Since I started my internship on February, on weekends, I have always had meals, watched movies, gone shopping, taken a walk, and done every activity by myself. I do not even have roommates.

This is fine most of the time, but it's really painful on times when I have a lack of self-confidence. I think it may even become dangerous later.

Whenever I see groups of people in the street hanging out with each other, a sense of envy grows in my mind. I wonder where they met each other, and how come they became so intimate to each other.

As a man at age 26, I want to meet some nice ladies too.

My major problems, as I think, are:

1. After 3.5 years of college life in which I had absolutely no social life, my introversion seriously exacerbated. I have an especially hard time getting close to strangers.

2. I thought my English was decent, but I found out that is only true when compared to other asian students' in colleges FOB, and these days I am more and more realizing that my English is not good enough to become close friends with English speaking people. Every day I meet people in my work, and I manage to express what I want to say, but often it's in a very awkward way, and even worse, when I am among many people talking, I can never take part in their conversation. (believe me, I literally suck without enough time and a dictionary)

3. I do not have a car, and for many people in the bay area it's okay, but for me it's a great hindrance to being social. Think about it, what girl would consider seeing an awkward guy even without a car!

What can I do? I imagined myself striking up a conversation with people sitting near at a cafe, standing at a queue, etc., but since I know I will not be able to talk like a normal American guy (not even close, when it comes to a small chat), I recoil.

I started fearing coming of weekends. To me it's just two and a half utterly lonely days that could have been spent in a more constructive way but repeatedly ends up being wasted and growing the self-hatred towards me.
