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 Digital Ocean NYC2 Droplets Down
One of my instances on NY2 is fine and the other one is sporadically accessible via SSH. Hope they figure this one out soon.
dangoldin··on How to find your Uber passenger rating
I spoke with a driver yesterday about it and he says he will basically pick up anyone above a 4. This was in NY so might mean different things in different places and to different people.
dangoldin··on WordPress on Heroku
Definitely. Only thing I wish is being able to use logic other than regex to handle which urls get cached and which don't.
dangoldin··on WordPress on Heroku
Another suggestion is to use Varnish. It's extremely easy to set up and just put in front of your Wordpress install, regardless of whether you're using Nginx/Apache.
dangoldin··on Kindle Unlimited
Ah got it. I spot checked a few and had a 0% success rate so gave up on more.
dangoldin··on Kindle Unlimited
How'd you find the overlap between the two? I'm trying to do the same but can't find a simple way to do it other than checking every book.
dangoldin··on Thanks, HN: You helped discover a disease and save lives
Touching story. A reminder that for all the gadgets we get, the internet is really about connecting and helping people.
dangoldin··on Rum Deal: America’s booze laws are terrible
Based on your description this seems very similar to Mancur Olson's "The Rise and Decline of Nations" - he provides an economic framework to think about special interest groups and why they tend to win out in terms of politics.
dangoldin··on Japan's Abe is the world's best leader right now?
Supposedly Bill Gates said the same thing when he was in Saudi Arabia and asked how it could compete. Something along the lines of it's going to be difficult when you're only using half your population.
dangoldin··on Bit.ly's shady business model
Although it sucks I wouldn't claim it's a shady business model. It seems more like the obvious one - make the custom URL option paid and they have their pricing clearly laid out - https://bitly.com/a/pricing

And you have a few days to crawl the URLs and see what you get.

dangoldin··on The case for banning laptops in the classroom.
My mom's a music teacher and this reminded me of a letter she wrote to the local newspaper after discovering they want to buy more computers for the classroom. Here goes:

I'm not denying that I am hopelessly old and outdated, but reading the article on Technology Needs for School District (May 15, 2014) literally made me cry; for two reasons. First, because the people who are in charge of education are actually going to do it, and second, that the Livingston parent community is so enthusiastic about it.

There is no doubt that computers are useful and that the Internet gives access to such a scope of information so quickly that is not available nor accessible through any other means. But how do they impact children's overall DEVELOPMENT? How do they impact their attention? With the pandemic of Attention Deficit Disorder, how can we be so blind not to notice the connection between children's attention span and the time they spend on the computer? I started teaching piano more than 30 years ago. EVERY child was capable to remember which note he had to play, with which finger, how to hold the finger and whether he had to play long or short, loud or soft - simultaneously. Now it is typical that when a child pays attention to what note it is, he does not notice which finger; if he remembers the finger – does not notice how loud, etc. I rarely see children that can actually focus on the task for longer than 20 seconds. I often ask parents, “How much time does your child spend on the computer?” The connection is direct: the less time on computer – the better the student's focus, the longer she can concentrate on the assignment. I happened to teach an elderly lady who brought a music book with her teacher's remarks dated 1958. She was nervous, “Will you quit on me? I forgot everything.” I answered (only half-jokingly), “Of course not, you are my only student with a normal attention span!”

Even though I observe 400+ students in my music school, can it be just coincidence? What does the beloved Internet tell us about the impact of computer use has on the brain? Nothing encouraging. As an example, there is a student work in biology (http://serendip.brynmawr.edu/exchange/node/336, 2007) that summarizes finding on the topic. It states what I suspected: computers often conflict with the activities that are needed for one to develop the ability to pay attention; the list of scientific works is attached there. And if you still like long books, N. Carr addresses the issue in his “The Shallows: What Internet is Doing to Our Brains.”

What are we doing? Are we trying to compensate for having poor teachers with technology? Why do we adhere to such a naive belief that computers are the solution to problems in schools, thinking that “the more of them - the better” automatically? Maybe it's better to invest in teachers' training? Maybe we need to raise the prestige of the teaching profession? I participated in a “professional orientation” day in LHS several years ago. Seniors had an opportunity to meet with representatives of their prospective field. I saw crowds of seniors following “Lawyers” and “Accountants”. In the “Teachers” room, a retired Harrison school teacher and myself, who were assigned to lead the meeting, found 4 or 5 girls. Only one of them really wanted to be a teacher, knew what is involved and why she wanted it. Everyone else said, “I do not know”, “I am not sure”.. . Why do we expect our children will be enthusiastic about learning if teachers themselves “do not know”?.. And how computers can help?

The more that children use computers, the less opportunities they have for human interaction. 
By increasing the role of computers in children's lives we bend human nature, we consciously under-develop the younger generation; we deprive our children of full development of their communication skills, ability to build relationships, and their creativity. We are raising USERS, not CREATORS. We are increasing the distance between those who are capable to make discoveries and those who can chose from pre-made options; between people who can see the beauty of the world and those for whom the world is limited by the rectangle of the screen.

dangoldin··on Show HN: Automatically convert a website to Android and iOS
Same with me - Aurora (31.0a2 (2014-05-27)) on OS X.
dangoldin··on Reasons to use protocol buffers instead of JSON
If it's too big of a change you can "proxy" it through a simple ProtoBuf to JSON converter.
dangoldin··on Bye Bye Passwords
I wrote a similar blog post a while ago advocating this approach. It was inspired by MixPanel sending me a login link alongside a forgot password link - http://dangoldin.com/2014/05/20/logging-in-through-your-inbo...
dangoldin··on EventHub – An open source event analytics platform
One of the first things I noticed when I checked it out. Both MixPanel and Codecademy are YC so I wonder whether there was any communication around it.
dangoldin··on What web developers thought of in the noughties as being MVC doesn't scale
Good read and echoes my experience. Something that I've been doing more and more recently is building more of my business logic into my models - that way no matter where they are used they maintain consistent behavior. This allows my views/templates/controllers to be extremely simple and lightweight and just reference the appropriate model methods.
dangoldin··on iMessage purgatory
I ran into this too and ended up calling Apple. Their solution was to tell everyone who had my number to erase their iMessage history with me.

Somewhat odd - I can receive individual texts from two people that have iPhones but if one of them sends a group text to both of us, I do not receive it.

dangoldin··on Teen Arrested for 30+ Swattings, Bomb Threats
I'm pretty far removed from this world of crime and only relay what I read coupled with my biased experiences but I suspect crimes build on top of one another. If you get away with a small crime earlier you'll end up breaking the seal and moving on to higher risk crimes. If you keep on getting away with it you end up taking on more and more risk. At the same time there are not enough resources to enforce a low level crime so fixing the underlying problems is a much better idea.

If you're interested in this topic take a look at When Brute Force Fails (http://www.amazon.com/When-Brute-Force-Fails-Punishment/dp/0...) - I found it a good take on crime in the US.

dangoldin··on Teen Arrested for 30+ Swattings, Bomb Threats
You're probably right but I think the cost of implementing this is low enough to give it a shot. It's not going to solve the entire problem and may not even solve 1% but might still be worth doing for the scenario where it does help.
dangoldin··on Teen Arrested for 30+ Swattings, Bomb Threats
Ah interesting - thanks for clearing this up. Yea that "sealed" record issue seems odd - I would expect it to be more along the lines of not being available rather than sealed so the requester doesn't actually know that a record actually exists.
dangoldin··on Teen Arrested for 30+ Swattings, Bomb Threats
Currently in the US when you turn 18 you end up "losing" your juvenile criminal record. A proposal I read that made sense was keeping the juvenile record hidden unless you end up committing a serious crime after 18. Once that happens your juvenile record is opened up again. At least that's an incentive to play it safe after turning 18.
dangoldin··on When a bad day gets worse – getting hacked twice in one day
I'm guilty of this for an old project and only discovered when Amazon sent me email telling me it was public so Amazon seems to be searching Github (the web?) for mentions of the keys.
dangoldin··on Parallelising Python with Threading and Multiprocessing
Yea - decent approach if you're doing a lot of IO but for computation you're limited by the GIL.
dangoldin··on The New Deal
Not sure if you meant a book on the web but I liked Venture Deals - http://www.amazon.com/Venture-Deals-Smarter-Lawyer-Capitalis...
dangoldin··on Readmill shuts down, team joins Dropbox
I agree. All these acquisitions just make me want to come up with self hosted versions that I can run on my own. I know there's ShuBook but the experience just isn't there.
dangoldin··on Readmill shuts down, team joins Dropbox
Damn. I'm more saddened by this than any other acquisition. Readmill is (was?) just so much better than the alternatives.
dangoldin··on Goodbye Gmail
That was more of a fun thing to add - the actual performance is noticeably slower for me. Both loading and navigating take a longer amount of time in Gmail. Probably should have just left that out since everyone seems to be drawn to disproving that particular point.
dangoldin··on Goodbye Gmail
Haha - I just did one "why is fastmail down". Gmail has that as the #2 spot so I consider it a tie =)
dangoldin··on Goodbye Gmail
Ha I wish. I'm not even paying for Fastmail yet =) Still have 55 days before I need to.
dangoldin··on Goodbye Gmail
Thanks for sharing - I'm only a few days in but have really enjoyed the snappiness and simplicity. I do wish it had better calendar support (for that I'm still on Google) and a bit more polish but so far I'm glad to pay for it.

The spam point is interesting - I plan on using Fastmail for my important personal stuff and gmail with forwarding for everything else. Hopefully that will make for a good tradeoff.
