sharing small pieces of rocks or jewels I find on the way

We use chromecast to see video from my laptop to TV. While pressing space would pause or play the video, there is no control for moving forward or moving backward. So I wrote a little javascript code

document.onkeydown = function(ev){if(ev.keyCode==37){document.body.firstChild.currentTime = document.body.firstChild.currentTime – 15} else if(ev.keyCode==39){document.body.firstChild.currentTime = document.body.firstChild.currentTime + 15}}

I run this code in console (pressing F12 and then selecting console and pressing enter after pasting) and then I can have keyboard control. Now if I press right arrow it goes 15 seconds ahead and pressing left goes back 15 seconds. If you don’t like 15, feel free to change the code to 10 and hit enter, it will be applicable instantly.

I haven’t been programming for very long time and have no idea how to make chrome extension. Should checkout, but don’t get enough time, too many things to read. So, wish to get it done by doing smallest possible :)

Answer on @Quora by @yushunwang of How does how-old.net work?

Answer by Eason Wang:

I directly worked on this project. The backend code is built by my team in Bing in collaboration with Microsoft Research. To be honest, it's a big surprise to me that this tiny web app went viral. I did some post analysis on why it went viral and wrote a blog post on Medium.

Back to the main topic, I want to answer this question in two parts. First part I will talk about how to quickly implement the exact same capabilities in any app. In the second part, I will go a bit deeper to describe the technology itself.

In Bing Image Search we have built the best in industry image understanding capabilities in the past few years. It was used in Bing and quickly expanding to other Microsoft products. Now it is open to all developers: Microsoft Project Oxford Home. In order to implement the same capability in an app, you can simply call the web API and get all the necessary information back in JSON format. You can give it a try by uploading an image here: Page on www.projectoxford.ai. It gives the data back in seconds. The face coordinates, gender, age information are all included. Face API is just one of the many features that we have made open in Project Oxford. There are many other core capabilities in the API to empower innovative scenarios. I am very excited to see this Microsoft internal API open to all developers and I know this will have profound impact to the developer world because the previous impossible scenarios are now just one simple web API call. #HowOldRobot was just one tiny demo to show off these capabilities. It was put together by one developer from Azure ML team just in one day.

How Old Do I Look? mainly relies on 3 key technologies  (i.e. face detection, gender classification and age detection). Face detection is the foundation for the other two. For age detection and gender detection, they are just classic regression and classification problems in machine learning. It involves facial feature representation, collecting training data, building regression/classification models and model optimization. There are plenty of publications in this area. Let me know if you have enough interest to go deeper.

On the other hand, deep learning and large scale data understanding have led to a new breakthrough of image understanding. This opens a door to more intelligent systems and APIs. You can check out my latest blog to understand how the Image Graph works to power advanced scenarios. http://blogs.bing.com/search-qua…

How does how-old.net work?

Answer by Jonathan Brill:

You have understated (severely) what Bill Gates is doing. It would be one thing if he was sitting in his ubermansion outside of Seattle and just writing checks for every attractive greenpeace undergrad that smiled at him. Bill Gates is flying to countries on the do not fly to list and meeting with dictators that are on the shoot on sight list and using his fat ass bank account as leverage to get their cooperation in distributing food and medicine to their people.

Bill Gates probably sat down with his wife at the beginning of it all and she was like, "Hey Bill, we should like, save all these people." And he was like, "Cool, write a check." And she was like, "Yeah so its not that simple." And then he was like, "You want me to do what? You do know I'm the richest dude within missile range, right? We could just waste away in pampered luxury wherever we want?" And she was like, "Pleeeeeeeeeease." And he was like, "Shit, alright, it can't be harder than killing all those tech companies in the nineties." And then all he did was start a worldwide consortium to strong arm billionaires into donating half their money to a fund, and then use that fund as leverage to strong arm the shitty politicians of the world not into helping him, but into at least letting him help their people. Even when it's not in their best interests.

He gave an interview recently where someone asked him, why are you able to do all these things ambassadors and activists and Bono and other people weren't able to do. And he looked at the guy and was like, "I've got billions of #$%&*# dollars and I'm making people do shit," or something to that effect. Imagine evil Bill Gates of the RealPlayer/Netscape assassination era but focused on doing good. He's like Batman right now. I'm not even sure everything he's doing is legal. But sometimes you need someone who can walk into the Congo with a jacked up haircut and enough money and gumption to threaten a coup to make a change in the world.

Bill Gates should be everybody's hero.

Does Bill Gates get too much credit for his donation to charity?

A beautiful story

Answer by Susan Lyon:

I was in my late 30’s, three children, recently divorced, working two jobs, trying to stay afloat.  My second job was that of a waitress and I worked a couple nights a week and Sundays.  Not a lot of employees wanted the Sunday shift.  We were on a major highway for beach traffic.  Sunday traffic consisted of sunburned children who were cranky and tired, bad tipping (mostly because they spent too much on amusements, hotels and restaurants) and parents who were regretting having to return to work the next day.  Sunday’s could be busy, but mostly, they were on the slow side. 

One Sunday, a family of four came into the restaurant and sat down – Dad, Mom, two children – one girl approximately 7 and one boy around 5.  It was a slow day and a storm was approaching.  The little boy was quite talkative and I found out just about everything they did the week before.  They were the only table in the restaurant and ate dinner and relaxed while the storm passed.

I should let you know I love rainbows.  I sometimes feel like I am a rainbow chaser.  People like me know the look and feel when rainbows should appear in the area.  As a matter of fact, my kids to this day, call me when they see a rainbow.  That being said, after the storm I noticed that look.  Went out back and saw the most beautiful rainbow.  (sigh)  Checked on the table and asked the parents if I could take their kids to see the rainbow.  I could see the glance between them, probably wondering if I was a kidnapper, but that quickly passed as I described the sheer beauty of what was happening right outside the door.  Told them we would be right out front and they could come too.  They let the children go with me while they paid the bill.

The little boy grabbed my hand and we walked out and sat down on the curb.  By now there were two rainbows and working on a third.  I explained a little science and the children were just amazed.  They had never seen real rainbows only ones in pictures.  The parents came out and we all sat there and watched for a few minutes at the wonder of the rainbow.  Another car drove into the parking lot and I knew this had to end because I was about to get another customer.  We said our goodbyes.

A year later, working one Sunday, I had a family come into the restaurant and sat down – Dad, Mom, two children – one girl and one boy 5.  When I approached the table, the little boy jumps up and says to me, “Can you make it happen again?”  I of course had no idea what he was referring to.  The mom and dad explained they had been in the year before and their little boy told everyone how he met someone who could make rainbows.  His sister kept telling her brother that it didn’t work that way and there would not be any rainbow and he should just shut up.  The young man was very convinced that I could indeed make it happen.  I didn’t know what to do, but I tried to explain as nicely as I could, that I didn’t think we would be able to see a rainbow that day.  It was a beautiful sunny day.  As I left the table, I could hear the little boy saying to his sister, “You just wait and see.”

Well, if you haven’t figured it out yet, there was a storm that blew in really fast.  The sky darkened and it poured for about 5 minutes and then all cleared up and what remained was a beautiful rainbow.  Now you may call this a coincidence, miracle, sign from above or just damn amazing.  All I know is there was one little boy who proved his sister wrong, amazed his parents and sat with me for a very long time on the curb calling me the rainbow maker.  Just to let you know, I got a damn good tip.

What are some great examples of coincidence?

One of the best piece I have ever seen in Quora – how to be a designer

Answer by Karen X. Cheng:

I got my job as a designer without going to design school.

I wanted to change careers and become a designer, but I didn’t have four years and $100k to go back to school. So I decided to teach myself. At first, I had a lot of doubts on whether someone could teach themselves well enough to get a job.
If you’re wondering the same, the answer is yes.

I hacked together my own design education in 6 months while working a full-time job. I didn’t think I was ready but started applying for jobs anyway — and got a job at a great startup, Exec.

I’ll admit, I’m nowhere near as good as many design prodigies that come out of a 4-year education at an elite school. But I’m definitely good enough to do my job well. I design a pretty wide range of things — for the website, iPhone app, emails, social media, and print.

Maybe you want to change careers and become a designer full-time.
Or you just want to learn some basics for your startup or side project.

This is a guide to teach yourself design.

Step 1. Learn to see
The biggest mistake is jumping into Photoshop too fast. Learning Photoshop does not make you a designer, just like buying paintbrushes doesn’t make you an artist. Start with the foundation.

First, learn how to draw.

  • You don’t have to sit in a room with a bunch of other artists trying to draw a naked woman.
  • You don’t even have to get that good at drawing. Just learn some basics so you can be comfortable sketching with a pen.
  • You only have to do one thing to learn how to draw: get the book You Can Draw in 30 days and practice for half an hour every day for a month. I’ve looked at a lot of drawing books and this is one of the best.

Learn graphic design theory

  • Start with the book Picture This. It’s a story book of Little Red Riding hood, but will teach you the foundations of graphic design at the same time.
  • Learn about color, typography, and designing with a grid. If you can find a local class to teach the basics of graphic design, take it.
  • Go through a few of these tutorials every day.

Learn some basics in user experience
There are a lot of books about user experience. Start with these two quick reads that will get you in the right mindset:

Learn how to write

  • Don’t fill your mockups with placeholder text like Lorem Ipsum. Your job as a designer is not just to make pretty pictures — you must be a good communicator. Think through the entire experience, choosing every word carefully. Write for humans. Don’t write in the academic tone you used to make yourself sound smart in school papers.
  • Read Made to Stick, one of my favorite books of all time. It will teach you how to suck in your readers.
  • Voice and Tone is a website full of great examples of how to talk to users.

Learn to kill your work

  • This is the hardest step in this whole guide.
  • Be prepared to kill everything you make. Be prepared to violently slaughter your precious design babies. The sooner you can embrace this, the better your work will become. When you realize your work isn’t good enough, kill it. Start again.
  • Get another pair of eyes. Ask for feedback on your work from people who care about design. Don’t know anyone? Make some designer friends — go to designer meetups and events.
  • Get the opinion of people who don’t care about design, too. Show your work to people who would be your users and ask them to try your website or app. Don’t be afraid to ask strangers — I once took advantage of a delayed flight by asking all the people in the airport terminal to try out an app I was designing. Most of them were bored and happy to help, and I got some great usability feedback.
  • Listen. Really listen. Don’t argue. If you ask someone for feedback, they’re doing you a favor by giving you their time and attention. Don’t repay the favor by arguing with them. Instead of arguing, thank them and ask questions. Decide later whether you want to incorporate their feedback.

Step 2. Learn how to use Photoshop and Illustrator
Hooray! Now you’ve got a pretty solid foundation – both visual and UX. You’re ready to learn Photoshop. Actually, I recommend starting with Illustrator first and then moving on to Photoshop after. Illustrator is what designers use to make logos and icons. InDesign is good for print design like flyers and business cards.

Learn Illustrator

  • There are a ton of books, online tutorials and in-person classes to learn Illustrator. Choose the style that works best for you. Here are the books I found especially helpful to learn the basics of Illustrator:
  • Adobe Illustrator Classroom in a Book – It’s boring, but if you get through at least half of it, you’ll know your way around Illustrator pretty well.
  • Vector Basic Training – This book teaches you how to make things in Illustrator that actually look good.
  • Now for the fun stuff! Follow these online tutorials and be impressed by what you can make. Here are two my favorites – a logo and a scenic landscape.

Learn Photoshop

Step 3. Learn some specialties
Do you want to design mobile apps? Websites? Infographics? Explore them all, and pick and choose the ones you enjoy to get better at them.

Learn Logo Design

  • Learn how to make a logo that doesn’t suck: Logo Design Love
  • You’ll want to take it a step further than a logo though. Learn to create a consistent brand – from the website to the business cards. Check out this book, Designing Brand Identity.

Learn Mobile App Design

  • Start with this tutorial to get your feet wet on visual design for mobile apps.
  • Read this short but very comprehensive and well-thought out book on iPhone design: Tapworthy. It will teach you how to make an app that not only looks good but is easy to use.
  • Geek out on the apps on your phone. Critique them. What works and what doesn’t?

Learn Web Design

Now for the hairy question of whether you need to know HTML/CSS as a designer: It depends on the job. Knowing it will definitely give you an edge in the job market. Even if you don’t want to be a web developer, it helps to know some basics. That way you know what is possible and what isn’t.
There are so many great resources to learn HTML and CSS:

  • My favorite free one is Web Design Tuts.
  • My favorite paid one (pretty affordable at $25/month) is Treehouse. If you’re starting from the beginning and want someone to explain things clearly and comprehensively, splurge for Treehouse tutorials.

Step 4. Build your portfolio
You don’t need to go to a fancy design school to get a job as a designer. But you do need a solid portfolio.

How do you build a portfolio if you’re just starting out for the first time? The good news is you don’t need to work on real projects with real clients to build a portfolio. Make up your own side projects. Here are a few ideas:

  • Design silly ideas for t-shirts.
  • Find poorly designed websites and redesign them.
  • Got an idea for an iPhone app? Mock it up.
  • Join a team at Startup Weekend and be a designer on a weekend project.
  • Enter a 99 designs contest to practice designing to a brief.
  • Do the graphic design exercises in the Creative Workshop book.
  • Find a local nonprofit and offer to design for free.

Resist the temptation to include every single thing you’ve ever designed in your portfolio. This is a place for your strongest work only.

Steal, steal, steal at first. Don’t worry about being original – that will come later, once you are more comfortable with your craft. When you learn a musical instrument, you learn how to play other people’s songs before composing your own. Same goes for design. Steal like an artist.

Go to Dribbble for inspiration on some of the best designers. Check out pttrns for iOS inspiration, and siteinspire for website inspiration.

Step 5: Get a job as a designer
When I first started learning design, I went to a job search workshop for designers. I walked into a room full of designers who had much more experience than I did – 5, 10, 15 years experience. All of them were looking for jobs. That was intimidating. There I was, trying to teach myself design, knowing I was competing with these experienced designers.

And yet less than a year later, I got a design job. There was one key difference between me and many of the other designers that gave me an edge: I knew how to work with developers.

The biggest factor to boost your employability is to be able to work with developers. Learn some interaction design. Learn some basic HTML and CSS. Designers in the tech industry (interaction designers, web designers, app designers) are in extremely high demand and are paid well. That’s where the jobs are right now.

If you don’t have any experience working with developers, get some. Go to Startup Weekend, go to hackathons, or find a developer through a project collaboration site.

Make a personal website and make your portfolio the centerpiece.
Go out and make serendipity happen – tell everyone you know that you’re looking for a job as a designer. You never know who might know someone.

Research companies and agencies you might be interested in. Look on LinkedIn for 2nd and 3rd degree connections to people who work at those companies and ask for intros. The best way to get a job is through a connection. If you don’t have a connection, there’s still a lot you can do to give yourself an edge.

Once you’ve got the job, keep learning
I’ve been at Exec for a year now and have learned a ton on the job. I seek out designers who are much more talented than I am, and learn from them. I find design classes (good online ones are Skillshare, General Assembly, Treehouse, and TutsPlus). I work on side projects. I geek out at the design section of bookstores. There is still so much to learn and to improve on.
Keep your skills sharp, and always keep learning.

Questions? Say hi at @karenxcheng. If you decide to start learning design and want to seriously commit to practicing everyday, drop me a line at karen (at) danceinayear (dot) com. I’m running an experiment to help keep you motivated.

“Nobody tells this to people who are beginners, I wish someone told me. All of us who do creative work, we get into it because we have good taste. But there is this gap. For the first couple years you make stuff, it’s just not that good. It’s trying to be good, it has potential, but it’s not. But your taste, the thing that got you into the game, is still killer. And your taste is why your work disappoints you. A lot of people never get past this phase, they quit. Most people I know who do interesting, creative work went through years of this. We know our work doesn’t have this special thing that we want it to have. We all go through this. And if you are just starting out or you are still in this phase, you gotta know its normal and the most important thing you can do is do a lot of work. It’s gonna take awhile. It’s normal to take awhile. You’ve just gotta fight your way through.” ― Ira Glass

How do you get a job as a designer without going to design school?

Answer by David S. Rose:

I'll give the questioner the benefit of the doubt and assume that this is being asked in good faith. No, it is not remotely OK. Out of my entire portfolio of 90+ companies, including quite a few that are well past Series A and profitable, there is a not a single CEO who is drawing even close to that.

Unless there is something extremely unusual about this situation (such as that the CEO is also the founder, who has invested a few million of his or her own cash, and has some special need for a big salary, such as a terminally ill spouse) that level of cash compensation would be entirely out of line. In my personal experience with companies that are pre-significant-revenue, the median CEO salary range seems to be about $75K-$125K. In some cases with later stage (post Series A) companies with significant revenue and a more mature founder (say, +/-50 y/o) with high living expenses (kids, schools, mortgage, etc.) it might sneak up close to $200K, but that would be an exception.

In the startup world, a CEO's compensation is usually taken in the form of equity, not cash.

Is it OK for the CEO of a startup to draw $350k?

From: 'This Stuff Doesn't Change the World': Disability and Steve Jobs' Legacy | Wired Business | Wired.com

A comment by Westcliffe Courtland:

My youngest brother has muscular dystrophy and is now quadriplegic, with just about enough movement to steer his electric wheelchair.  A few years ago my mom found that someone had put together a bluetooth computer controller allowing the user to control the computer using the wheelchair joystick. The family clubbed together a bought him an iMac with a plan to give him back some of his independence.  It all connected wonderfully, the mouse moved, some keyboard software and we were set..  we thought.

The only problem was that the mouse move juddered, pausing then racing across the screen to catch up with the movement, rendering the whole set up useless.  A lot of testing later, showed that it worked perfectly on a Windows PC, just failed on the iMac.  My mom spent a lot of very frustrating time talking to Apple support here in the UK, who essentially said that it was an unapproved bluetooth device and tough luck we were on our own. 

Out of sheer frustration my mom wrote an e-mail to Steve Jobs venting her frustration at what was happening, never expecting a reply. The surprise was a remarkably prompt, somewhat curt (as he was prone to) reply from him.  He had assigned a group of technicians and programmers to resolve the problem.  They carefully researched the problem and discovered that it was due to a very slight error in the implementation of the Bluetooth stack in OSX that was almost unnoticeable.  They then built my brother a bespoke update to OSX to solve the problem.  An update which appeared a couple of updates later in the routine updates for everyone else. 

This brief interaction with Steve Jobs resulted in an effect that changed my brothers life and had a huge, wonderful effect on my family.  We never thought a CEO of a corporate would care.  He did, he didn't have to, but he diverted resources to make a difference to just one person, the difference between dependence and independence in a number of important ways.  Thank you never seemed enough for what was done and for all he did in the corporate world and all of the incredible things he introduced to the world it is for this one act of human kindness he will forever be in the heart of me and my family.

What are some great stories about Steve Jobs?
