jon_dahl··on Why the Creators of Zencoder and Video.js Started Mux
FWIW, we feel pretty good about the market size we're tackling. YouTube and Netflix are massive, but you might be surprised how much video is delivered by media companies and non-video technology companies on their own platforms, and the whole thing is growing.
jon_dahl··on Why the Creators of Zencoder and Video.js Started Mux
Yep, we work with a few players now, and have several others in development. Ultimately, we'll work with every major web player and mobile/OTT device. You can also roll your own integration if you have a custom player, though if it's HTML5-based, the HTML5 integration might have you covered.

Today, we're focused on the performance side of things: errors, startup time, rebuffering, and video quality. Over time, we'll go more places.

As for the most impressive features: we're still early (just coming out of beta), and so some of the things we're most excited about are coming down the pipe. As a preview, though, one of the challenges we're tackling is extracting meaning out of streams of data, and so we're working hard on things like alerting and dashboards that surface the most important information (while also making it easy to do your own explorations). That's also why we've spent a lot of time on our interface; we think a good UX is really important to a product like this.

jon_dahl··on Why the Creators of Zencoder and Video.js Started Mux
Hey everyone - Jon from Mux here. We've been hard at work on this since January, and are excited to start showing off what we're working on. Happy to answer any questions, or take any feedback!
jon_dahl··on Mux (YC W16) Is Google Analytics for Video
Our bad. Fixed now.
jon_dahl··on Tesla Intrigue Deepens with Musk's Twitter Barrage
I think the whole point of Tesla is to be an excellent car company. "Electric" and "self-driving" just happen to be two attributes of an excellent car company at this particular point in history.
jon_dahl··on Fundraising Advice for YC Companies
From the inside, there is far more talk at YC about building a good business and getting profitable than about raising money. PG has advocated this for a long time[1], and YC continues to encourage this.

The YC way is "Make something people want." Fundraising is a distraction that is occasionally necessary.

jon_dahl··on Former Stanford dean explains why helicopter parenting is ruining a generation
What a false dichotomy: Stanford or life as a service worker. Both Google and YC have stopped focusing on college prestige in their hiring/acceptance, because it wasn't a particularly strong indicator of success.

I would much rather send healthy kids to a state school or liberal arts college than unhealthy kids to Stanford.

jon_dahl··on An Interview with Neal Stephenson
I had the same experience with Anathem. It is a little hard to get in at first. But about 200 pages in, it really starts rolling. Great mix of world, plot, characters, and ideas. (Ultimately, it is a mashup of Plato and quantum mechanics.)
jon_dahl··on Announcing Docker Machine, Swarm, and Compose for Orchestrating Distributed Apps
A lot of people have this fear. Amazon is a quickly expanding platform with a growing level of lock-in and immense power. This isn't good for the ecosystem - a dominant company can charge a premium, and choice is good.

Full disclosure: I say this as a founder of a higher-level cloud service (Zencoder) that Amazon decided to compete with head-on. We're doing just fine, thanks (growing quickly, differentiated product), but Amazon is aggressively expanding upstream and is going to continue to do so.

jon_dahl··on Bitcoin Startup Circle Secures $17M Venture Financing
Don't you mean:

Sell your company for $360M. Join the new company as CTO, and sell for $3.4B. IPO your next company. Get millions in VC. Foolproof.

jon_dahl··on Ask PG: How would you fill out a YC application with YC as your idea?
Be careful, though. For every legitimately good startup that gets to know the YC partners through other channels, there are 1,000 founders who just look desperate.

You only have so much time. Building a great company is the most effective way to get into YC.

jon_dahl··on This is a web page
Quick answer: links. Hypertext. It's important enough to the original vision of this whole contraption to actually be the name.

While were reminiscing... In 1994, the web felt like technology. You typed in "http://" and it felt exotic. You were connecting to a server. Literally: _a_ server. You wondered what would happen if you hit the same address with gopher or (more likely) telnet.

As often as not, something would happen.

jon_dahl··on Poll: Full-time software engineers in the Bay Area, what's your annual salary?
If you're a non-junior engineer, and one of the first ~10 employees, this is fairly common. At least at the point of issuance; 2-3 VC rounds reduces the percentage (but increases the value, at least in theory).
jon_dahl··on Box Acquires Crocodoc (YC W10)
This is the way to do it. Not every acquisition means that customers lose.
jon_dahl··on Do Elite Colleges Discriminate Against Asians?
This is a strange distinction. It sounds like you're defining "discrimination" as "judgment" or even just "making a decision", whereas you're defining "prejudice" in a way that most people would consider a synonym for "discrimination".

I'm also not sure what that has to do with this article (which doesn't hang on any particular definition).

jon_dahl··on Ask HN: Who is hiring? (March 2013)
Zencoder - San Francisco - Ruby Engineers, Video Engineers, and Dev Ops

Zencoder transcodes millions of videos each month for a thousand customers like Khan Academy, IGN, NFL, and Amazon. We're a small team of really talented engineers solving hard problems and making developers happy. Great product, office, team, and perks.

http://zencoder.com/jobs

We also have opportunities in Boston for engineers at Brightcove (who acquired Zencoder last year): http://www.brightcove.com/en/company/careers/open-positions

jon_dahl··on Ask HN: If you would launch a website in 4 hours, what would it be?
People come to Zencoder wanting this, but it isn't really what we do. Not sure how big it is, but there is a market for this.
jon_dahl··on Amazon Elastic Transcoder
Zencoder here. Amazon has done a good job of making their pricing look simpler/cheaper than ours, and for some customers, it is. Two quick comments.

1. Our larger customers don't pay more than this already.

2. Paying 33% less doesn't necessarily mean getting 33% more value.

We'll be writing up an analysis today. Off the record (ahem), we've known about this for a long time, and we aren't worried.

jon_dahl··on Amazon Elastic Transcoder
We've thought hard about Opus, FLAC, and ALAC. Don't be surprised if you see those soon...
jon_dahl··on Why it's so hard to find a photo of Neil Armstrong on the moon
The biggest problem with conspiracy theories is the cover-up. I don't deny that governments are capable of lying and doing terrible things (cf. early CIA). But I can't accept the idea that a massive conspiracy would stay secret. Any of the hundreds of conspirators involved would be an instant millionaire celebrity for breaking the news.
jon_dahl··on Raising Money After Bubble 2.0
Other than Facebook and Zynga stock prices, is there other evidence that a bubble has popped? I haven't seen signs of funding or liquidity drying up. Valuing Facebook at $50 billion rather than $100 billion could be the sign of a massive slowdown in Silicon Valley... or it could just be a market correction to Wall Street hype.
jon_dahl··on Jonah Lehrer Resigns From The New Yorker After Making Up Quotes
Wow, the case is really weak. And I don't even like Malcolm Gladwell.

In 2007, Gladwell took up the financial industry’s cause. He argued that Enron’s investors were to blame for their losses, rather than accounting fraud, which he dismissed. His "analysis" was debunked and mocked by U.C. Berkeley Economics Professor Brad DeLong.

That same year, 2007, Gladwell hailed ex-Goldman Sachs CEO Hank Paulson’s move to head the Treasury Department, praising him for being among those “self-selected toward public service. . . ” Gladwell did not mention that Paulson saved himself roughly $100 million in taxes by moving straight from Goldman Sachs to Treasury.

He's a contrarian. Maybe wrong, maybe even stupid. But that is different than corruption.

jon_dahl··on Brightcove Acquires Zencoder (YC W10)
Hi Steve - we have express plans to _not_ shut down or make you go back to a homebrew setup. This isn't an aqui-hire; Brightcove is getting into the encoding API market. Hope to work with you for many years to come.
jon_dahl··on Google Compute Engine vs. Amazon EC2: Video Transcoding
Hi DMV - we ran the transcoding tests a few times, but transcoding performance is pretty steady across multiple runs (here and elsewhere).

Network obviously isn't; the numbers here include about a dozen test runs. We should make that more clear. Even a dozen isn't enough to be a scientific test, so hopefully we (or someone else) will do more benchmarking in the future.

jon_dahl··on Dalton Caldwell: Announcing an audacious proposal
This is a tangent, but Dalton is actually a really charismatic speaker. He was probably the favorite speaker of my YC class, and was reportedly great at Startup School a few years ago (though I wasn't there). Must come off better in person.
jon_dahl··on Pinterest Raises $100 MM at $1.5Bn Valuation
You're ultimately right, though future EBITDA (or future dividends) is more interesting than current EBITDA. Otherwise a pre-launch startup with no revenue and interesting technology would be worth $0, and a declining company with $1B of EBITDA would be worth the same as a growing company with $1B.

The question is whether Instagram can eventually contribute enough to Facebook's bottom line to justify the $1B valuation. Its current (lack of) revenues obviously don't get it there, but it's the future that matters.

jon_dahl··on My Doctor's Office Asked Me To Lie
"How about if I add 'not' to make it a true statement?" She accepted this. So I had my appointment.

That is an elegant solution to the problem.

jon_dahl··on I don't hire unlucky people
I'm with DarkShikari - this is a great article.

Hiring is one of the most important things for any company, at any stage, that it is worth doing right. If interviewing 100 people instead of 50 will increase overall talent, it's worth bending over backwards to do this. Even if it means sacrificing in other areas.

Ultimately, everyone ends up using heuristics at some level. But it is worth being very careful what heuristics you use, and the article does a great job of demonstrating this. Do you really want to exclude excellent developers who didn't major in CS? Do you really only want to hire engineers who self-identify as rockstars? Maybe - but be conscious about what you're doing.

jon_dahl··on The House Y Combinator Should Have Built
Here is where Zencoder was born: http://yfrog.com/09x7fsj.

We went a little outside of the Mountain View area and got a house in the Santa Cruz mountains. It was great. Three desks, three computers, three bedrooms, a nice kitchen, and a hot tub - perfect for those cold February days. There was a country store up the road, but not much else for miles around. Nothing to distract us except for redwoods, wild animals (turkeys, mice, deer, a scorpion), and the occasional storm. But still, we were only 30 minutes from Mountain View and 40 minutes from Palo Alto - closer than if we had lived in San Francisco.

Those were the 4 most productive months of my life.

jon_dahl··on How Yoga Can Wreck Your Body
Exactly. Other things that can wreck your body: running, weight lifting, competitive sports, and failing to do any of these things.
