Currently leading engineering team @ TripleLift (http://triplelift.com/). Formerly I cofounded Makers Alley (http://makersalley.com) and Pressi (formerly Glossi) (http://getpressi.com/dan). Before that I had a stint as a wall street quant, a management consultant, and a brief stint as a product manager.

I write at http://dangoldin.com.

I do a minimal amount of consulting on work with a focus on quantitative engineering, scaling systems, and architecture review. If you have an interesting project with some fun challanges definitely reach out!

dangoldin··on Ask HN: Who is hiring? (January 2016)
TripleLift | NYC | ONSITE | Full Time | Lots of positions (jut ask!)

We're a rapidly growing company in the quickly growing advertising space so if you're interested in working with large systems and getting an understanding of how the modern web works it's a great place to be. I realize that adtech isn't the most world changing industry but in terms of engineering knowledge and dealing with all elements of the tech stack it's pretty incredible and a good place to be.

There was also a post here on website bloat and we do try to keep things lean and simple - our goal is to strike that perfect balance between content consumers, publishers, and advertisers and we realize the industry's in a pretty crappy spot right now and are trying to make it better.

Definitely reach out if you have questions: dgoldin@triplelift.com

Edit: Languages are Java, Scala, Python, JavaScript, some R, some PHP.

dangoldin··on Blade: a Java Web Framework
That's the first thing I looked at - whether these were Netty based. We've been using raw Netty for our core application and it's been amazing.
dangoldin··on Pondering Homejoy’s Failure
Two years ago I was wondering why there was such a glut of these cleaning startups. The entire idea of applying the Uber model just didn't make sense - one is a commodity product with no way to bypass the middleman while the other requires letting someone into your home and encourages going off platform.

Dug up the old post for those interested - http://dangoldin.com/2013/12/09/why-are-there-so-many-cleani...

dangoldin··on Is media consumption zero sum?
Good point - I'm one of the few drivers who like doing it in silence so definitely biased.

Agreed that measuring consumption is tough - even if it's as simple as measuring an ad view, ad click, and then a purchase you need to take into account everything the customer has seen before. No way to currently measure something like that.

We're going to be stuck in perpetuity with John Wanamaker's: "Half the money I spend on advertising is wasted; the trouble is I don't know which half."

dangoldin··on Is media consumption zero sum?
That's definitely fair - I was approaching it from the measurement perspective but I'm not sure there's a real distinction. Think of the use scenario of the self driving car - that's a bunch of time that's immediately opened up that was used doing something else and can now be filled with consumption. Of course we have a max of 24 hours * our concurrency level each day but we're nowhere close to saturating that.
dangoldin··on Is media consumption zero sum?
I agree that high quality content makes it more enjoyable but do you think part of that has also been more time to enjoy the new content?
dangoldin··on Oyster is shutting down
I tried Oyster and ended up canceling after discovering that the books I wanted weren't available. The case is the same with Kindle unlimited.

The problem is that publishers make sure that the high demand books just aren't available via an "all you can read" plan so these end up with the scraps.

dangoldin··on Oyster is shutting down
Same here. Wish I had Readmill again.
dangoldin··on Ask HN: Who is hiring? (May 2015)
TripleLift - http://triplelift.com/ - New York, NY - Full Time

We're looking for all types of engineers to help scale our tech. We've found our product market fit and are growing quickly. I joined 18 months ago when we were 13 people are now over 50 and just moved into a new office space. We're currently focused on scaling our tech so there are lot of opportunities to do interesting and challenging work.

Our core product is a native advertising ad exchange that allows publishers (website owners) to ditch banner ads in favor of native ads that will allow them to design their sites the way they want without having to worry about monetization from the beginning. When they are ready they include a bit of JavaScript and we will dynamically resize/crop ads and leverage their existing HTML and CSS to make sure the ads fit with the look they're going for.

There's a lot of interesting work we're doing with computer vision, high performance networking, as well as quantitative engineering to help build out our bidders.

Feel free to email me at dgoldin@triplelift.com with any questions!

TripleLift - http://triplelift.com/ - New York, NY - Full Time

We're looking for both back and front end developers to help scale our tech. We've found our product market fit and are now focused on execution - we've been redesigning and rewriting a series of applications to be highly performant and concurrent since we're seeing significant volume now and trying to get ourselves ready for the next step.

dangoldin··on Timesheet.js
Pretty cool - there's a similar library at http://timeline.knightlab.com/ that approaches the problem in a slightly different way. Rather than having an axis per event they try to present multiple events on the same axis.

TripleLift - New York, NY - http://triplelift.com/

We're rapidly building out the engineering team and are looking for both front and backend developers. On the front end we're using AngularJS and on the backend we're primarily Java but looking at Scala for a few use cases. We're working on some fun problems including real time bidding, image analysis, and rebuilding a lot of our existing components for scale.

If you have any questions definitely reach out - dgoldin@triplelift.com

Also not on the list and doesn't take place in SV but I loved it and the culture is very SV like - http://www.amazon.com/Skunk-Works-Personal-Memoir-Lockheed/d...
dangoldin··on Elasticsearch for Beginners: Indexing Your GMail Inbox
I've been using github pages as a blogging tool since it makes linking between various posts easier but if you're primarily writing about code this may be even better since the code is easily accessible.
dangoldin··on Let the Other 95% of Great Programmers In
Using the same argument we should be investing more in the groups that traditionally haven't been into programming - women and minority groups. They are already US citizens without needing a visa sponsorship.
dangoldin··on Adventures in Piano Building
This is a great post! Thanks for sharing. Makes me want to pick up a hobby that involves something other than staring at a computer screen.
dangoldin··on Distracted Driving and the Risks of Ride-Hailing Services Like Uber
Just my experience but I spoke with a couple of Uber drivers in NYC and almost all were former taxi drivers that claimed Uber was safer. In a cab they'd always be on the lookout for passengers to pickup versus only having to click an area on a phone.
dangoldin··on PCH International in Talks to Buy Fab for $15M
Not so much worried about him - more the rest of the team but hopefully they learned a ton during the experience.
dangoldin··on PCH International in Talks to Buy Fab for $15M
A bit bittersweet for me. I had a failed startup a year ago where we were trying to connect consumers with local woodworkers and metalworkers. At the time, we attributed our lack of success to Fab and their ability to convince consumers to focus on discounts. We had a ton of other reasons for failing but ecommerce, especially for higher ticket items is extremely difficult and definitely sucks that they didn't make it work. On an abstract level I feel validated that their model didn't succeed but I also sympathize with the founders and the rest of the team. Hopefully they learned a ton and land on their feet.
dangoldin··on New Relic files S-1 for IPO
The 68.3% includes the 27.3% but still amazingly impressive!
dangoldin··on Ask HN: Who is hiring? (November 2014)
TripleLift - New York, NY We're an adtech company in the native space and are growing quickly. We help website owners monetize their sites by getting rid of banners and putting a bit of JavaScript that will allow them to include dynamically generated ads that match the look and feel of their site.

We're hiring across the board and our stack is Angular on the frontend, Node + Java on the backend, and a bunch of Python/R thrown around for data analysis. 2015 will be the scaling year so if you're interested in working on tech that scales and helping build out an engineering team that scales definitely reach out.

If you have questions feel free to reach out - dgoldin@triplelift.com

dangoldin··on Diary of a Corporate Sellout
Same. Learned a lot doing it but the events space is very difficult to grow a business in.
dangoldin··on Ask HN: My VPS got hacked and now I'm facing a massive bill. What can I do?
I had something similar happen with AWS but the bill wasn't as high since they ended up flagging my box as spam-producing and shut off all outbound traffic. I'd just ask them and see if they can remove the charges, it worked in my case.

dangoldin··on Why Python 4.0 won’t be like Python 3.0
Agreed - I really enjoy writing Python but the more I use it the more I run into concurrency and performance bottlenecks. I think the big win will be moving away from the GIL but I image that to be a big ordeal.
dangoldin··on Ubuntu Bug 255161: Openoffice can’t print on Tuesdays
Whoa that's pretty crazy. It seems the pattern is a 6 being mistaken for an 8 but surprised Xerox didn't release the upgrade when they discovered the issue. Why wait for someone else to call you out on it?
dangoldin··on Ubuntu Bug 255161: Openoffice can’t print on Tuesdays
This one's great! Thanks for sharing. Makes you wish there was a real cause though instead of speculation.

dangoldin··on Getting the most out of Lyft's 50 free rides
Yea - I definitely felt guilty but the driver was okay with it and when you get 50 free rides over 2 weeks you do have the incentive to use them all up.

If they gave fewer trips over a longer time frame I imagine people would be more conservative.

dangoldin··on Getting the most out of Lyft's 50 free rides
I think the problem is that with this much demand if a few people do this they will make it very hard for others to get a car - which will end up just annoying them about the Lyft experience. Lyft would prefer shorter rides that would be distributed around more people.

Now it's basically investors subsidizing a few long trips and pissing off other potential riders.
