Time Lapse Video of the Very Large Telescope
http://www.popsci.com/technology/article/2011-05/time-lapse-video-very-large-telescope-work-coolest-thing-youll-see-today
What makes this time lapse particularly amazing--because we’ve all seen plenty of time lapse videos of the night sky--is the four telescopes in the foreground. Watching these instruments work against a black background would be endlessly fascinating on its own. Unfortunately you won’t be able to pay them too much attention. Because damn, what a sky.

How do you answer interview questions on large scale system design?
I keep getting asked questions about large scale system design, especially from Amazon (how would you design Youtube/Twitter?). I never do well on them and it's keeping me from getting jobs. There's plenty of resources for answering coding questions, but I haven't seen any for large scale system desgin. Does anybody know of any resources, such as websites, books, lectures, etc.?
Show HN: Augmented Reality Knowledge Management for Facility Maintenance Teams
https://aircada.com/
Hello friends at HN. Aircada is an AR knowledge management platform to help facility maintenance teams capture, retain, and transfer knowledge. Here is a link to a demo video showcasing the features - https://youtu.be/QXwTlNC3C7A

During the pandemic, we noticed that some technical achievements from Microsoft's Spatial Anchors were finally at a point of opening the door to adoption for a magnitude of AR use cases, that in the past, weren't a viable option. And paired with the processing power and lidar capabilities of new phones, it seemed location based AR finally wasn't a pain in the a%% to use.

Until now, QR codes and advanced computer based setups were required, and just were not worth the effort for most.

But now, all with a mobile device - scan an area, place AR content, then scan that area again and have it show up exactly where you placed it. Awesome.

However, there were still some problems with Microsoft's system. Locating AR content sometimes took 30+ seconds, and cost up to a dollar to do.

So we built on top of their system and managed to cut that cost by about 10x, and increase the speed of locating content by about 10x. And by doing so, the use cases that opened up were quite vast!

With our backgrounds in industrial automation, we set out to address the following problem - The growing industrial skills gap.

The US Department of Labor estimated the 50% of the US workforce was set to retire over the next 5-10 years. In utilities and manufacturing, where turnover is high, this is becoming a huge issue.

Imagine Bob, a senior maintenance technician with 35 years of experience, about to retire. When Bob walks out the door, so do many of his trade secrets in how to operate the facility. After speaking with several managers at these facilities, there is an eery since of panic approaching, where they are wondering how they will transfer Bob's knowledge to the younger generation before it's too late.

Meanwhile, when hiring the younger generation, Bob continually has to hands on train these new hires with the same knowledge over and over again, just to watch them quit a year or so later.

And this is where location based AR can show some real value. If Bob can capture his knowledge and place it next to the machines where it'll live forever, and be accessible in seconds from any mobile phone, it's as if Bob never actually left. Sort of like Obi-Wan Kenobi in the original Star Wars. New hires will be able to train themselves with the autonomy they so desire, while Bob can continue addressing the facilities larger issues.

Anyway, I appreciate you reading, and I'll finish with this - we'd love to hear your thoughts, feedback, and or any questions you may have. The market and use cases for what we've built it quite vast, so narrowing it down has been one of the most challenging aspects.
Ask HN: Tips for finding FOSS in need of documentation help?
I've wanted to learn to program for a lot of years[1] while dealing with a raft load of personal issues, thus failing to learn to program. My current baby step goal is to submit at least one pull request per week so it becomes a natural and easy process for me.

I submitted my first pull request back in November for a typo in documentation. I submitted my second one today and it took more than a month to make that happen from the time I had the idea, including roughly a week of beating my head against the wall trying to sort out what I was doing wrong.

It seems like just doing some small pull request regularly so it becomes easy will take less time than relearning the process every few months. Given that I'm a writer by trade and I don't really program, finding typos in documentation (or similar) seems like the low-hanging-fruit option for me.

I don't know how to readily find places that need such help. I'm an outsider when it comes to the github ecosystem and all that.

I've tried to google it, etc. I'm not readily hitting pay dirt.

I'm hoping a few replies from people in the know will help me jump start this process, saving me weeks or months of spinning my wheels.

Thank you!

Show HN: My online food ordering start-up
https://www.crowdtilt.com/campaigns/help-couchster-build-an-app-and-maybe-upgrade-our-site-a-little
For the last few months I've been working on an online food ordering startup, and our initial site (www.couchster.com) is nearing completion. Initially, I wanted to do more than just food ordering (I also wanted to offer products like spa and salon reservations, grocery ordering, etc) but we decided to focus on a core product initially. Anyhow, I'm curious what people think and what jumps out as something to improve. We actually do have some cool technology in place that's not immediately apparent (our payment system is way better for businesses than Grubhub's or Seamless' for example), but I'm sure there are plenty of things we should work on.Additionally, we're currently running a Crowdtilt campaign to try and raise some funds to build an app and improve our site a bit further. To date, I've entirely self-financed, but I've only been able to stretch that budget so far and I can't cover an app as well, as much as I'd like to. Any help here, even if it's just helping spread some awareness of our campaign, would be hugely appreciated!

12 Things You Should Stop Doing in 2012

It’s the end of the year and already I am seeing the usual blog posts that either reflect on the year that was, or are pondering the year to come. I thought about writing another post covering all of the things that didn’t happen to me this past year but since I’ve already done that before I figured I needed to do something different. So I decided on this post instead. You’re welcome.

Here are the 12 things you should stop doing in 2012.

Successful businesses don’t need smarts
https://www.waterflowon.com/blog?category=2&article=41
By Nickle at Waterflowon.com

Let me show you

Make a good product; set a price above your cost; tell your customer you have what they want; make a mistake, fix it, and be honest with everybody; make fair deals with everybody

Any idiot can understand and easily do things right, because nobody will argue that it is wrong, or it just doesn't work for him. But why don’t people do things like successful companies?

Let me show you how "smart" people make it difficult to achieve business success.

They don't make a good product and improve it by heart, they cut corners instead. They believe they know their product, but their staff and customers don't. Actually, at least their staff can see that attitude clearly, and their customers can feel it, so their enemies are glad to spread the bad news when the product fails.

They don't set a price above their cost. In fact they don't know the real cost. If you cut corners, you will never know the real cost. You need really good designer, maker, and vendor; all these things together make for a good product and also a reasonable price. You can set a high price, but who will buy it? Finally, you are playing a must-lose game with yourself, only you don't think so. Your customers, your staff and even your competitors, they know, they all know.

They don't tell their customers they have what they want. Instead, they put their ads everywhere telling the whole world how good their products are, and shout at everybody passing by “buy me! buy me!” Why do they do this like a mad dog? They don't know who their customers are, not to mention their needs. So, a mad dog starts to run marketing.

When they make a mistake, they don't tell their customers, they don’t even tell their staff, because they have too many secrets and this is just a new one. They pretend nothing happened. Only when things become too serious and they start to lose control do they start to hire a pr company with lots of smart brains to figure out an even bigger lie to get them past the crisis. Then they file this big dirty secret away in their huge dirty library with the label: secret. Every time they host a party to celebrate this huge success. They don't care where this leads them. Actually, there is no easy way back.

They don't make fair deal with anybody, they always try to avoid it over trying hard to get more in any deal. They want their staff to work harder and get less, their vendor to offer better products with lower prices, they don’t want customers to know the product, and instead buy anything they offer blindly. Yes, it can happen one or two times, but you are not the only smart person in the world, and you can't make people do business with you, thus feeling stupid again and again. Eventually everyone will leave you: staff, customer, vendor, and even you will confused, thinking “if I am so smart when it comes to business, then why do things go badly?”

So stop being a smart business man, start running your business like an idiot, and you may find the thing you dream of, overnight success, even faster.

Pragmatic Unit Testing in JavaScript
http://blog.ponyfoo.com/2013/03/28/pragmatic-unit-testing-in-javascript
More often than not, companies completely (and irresponsibly) disregard JavaScript as code that should be unit tested. They might test their back-end code, it may be in C#, Ruby, Java, or even PHP, or just about any other language. But there's a good chance that the front-end code is thoroughly untested.

Integration level testing with tools such as Selenium is nice in theory, but way too impractical (you have to set up a server), and particularly slow (loading browsers and computing the recorded actions takes its toll). As such it's rarely part of build processes, and it's run manually (with a single command, but manually nonetheless).

So why is that JavaScript gets treated so differently from the rest of languages?
