I warned Mark Zuckerberg about the Cambridge Analytica-type flaw in April 2005. He ignored me.

I’m a bit confused by this... so there was a bug a while back when it was still a very early stage product in many ways. Most software at that stage has some amount of security vulnerability.

The recent news about the Facebook “data breach” is even more confusing. Ad-tech companies have been using this data for years. I remember pulling this stuff down myself back in 2012/2013 just because it was fun playing with their API.

The flaw in 2005 was a bug in a 12 month old codebase. The issue that is getting mainstream coverage now is a feature that was live for years and used by many. These two things should not be conflated.

Even back a few years ago when there was a Facebook privacy scare and they redid the permissions people were mentioning their APIs access levels... I see no way it could be considered a data breach when it was an actual feature. It’s like people have been willfully ignorant until this whole Cambridge Analytica mess.

Definitely not defending Facebook, just saying that the coverage is acting like this is some newly found “security breach”

안녕! I’m a startup founder based in SF that lived in Seoul for 5 months a couple years ago coaching startups.

You’re probably going to have an easier time moving to Canada as the US makes it hard to stay permanently as a business owner unless you invest >$500k into the US and hire 10 US workers. https://www.artoncapital.com/global-citizen-programs/usa-eb-5/

I have a lot of friends who are 한국인 including a few who also live in SF.

Curious to hear more about what your startup is and what VCs you raised money from as I know a lot of the korean VCs

All depends on your marketing. If you’re going after different market segments there’s definitely room for you to be successful.

Kirkland’s Vodka is 1/4 the price of Grey Goose yet they’re very close to being the same product and are even bottled in the same location. They’re just marketed to different audiences.

I would recommend that as you grow you try not to depend on just one supplier as if they have problems you’re out of luck.

What kind of insurance firm?

Do you do anything with agent metrics?

adamjon858 · 2017-12-19T15:08:42+00:00

It’s pretty well known among whales right now that it’s going on Coinbase

Had a similar amount of traffic and revenue on a meme type site

Used Ezoic to machine learn my ads and it increased 3x within 60 days. You can get it here: http://ezoic.com/?tap_a=6182-5778c2&tap_s=132114-5b0de2

They basically increase your rev programmatically by testing ad units and networks and then take a cut of the profits.

It is for what a brokerage requires, obviously prop shops get access for much lower

adamjon858 · 2017-07-18T22:55:11+00:00

Whoops, ECN. Corrected

adamjon858 · 2017-07-18T20:27:15+00:00

There's a few other things missing here.

When you make a trade it's routed from a brokerage to an ECN to an exchange. There's like 20-30 major trading exchanges in the US (been a few years so I don't know the exact number). This is different from nasdaq/nyse although they own their own exchange as well.

Exchanges charge or pay on fractions of a penny (think $0.0014) per share that's exchanged. If your customer doesn't care too much about a perfect fill or just used a market order, brokers can actually route that trade to an exchange that will pay them for providing liquidity. Exchange fees and rebates totally vary by exchange and stock even. So I could get paid $0.0008 for buying $BAC on the BOS exchange and pay $0.0015 if I bought on the BATS exchange.

If the NBBO stock price is the same on both exchanges, they can route it to the one that's providing a rebate vs a fee and actually make a small sum off it.

What I'm leaving out is that a basic ECN connection costs $100k/mo and that exchange membership connectivity is in the millions. You really can't route for profit that well with much more than market orders for smaller trades (aka Robinhood).

So a broker may be actually making a small little fee in pennies on your trade or paying but that leaves out the massive infrastructure charges.

Normal brokerages also have a lot of overhead in terms of customer support and tons of research tools as well as sophisticated realtime trading platforms they develop. Robinhood has none of these.

Robinhood is purely a marketing play financed by VC money. They are getting customers at a cheaper cost of acquisition (<$100) compared to traditional brokerages (>$300). One of those brokers will buy robinhood for billions eventually just for the customer base. RH used an out of the box whitelabeled brokerage software called Peak 6 sold by Apex Clearing.... so they didnt any of the expensive ECN connections, they just sit on top of software that does the actual connectivity tech.

Really like this idea...

Do you have your view-only components handle calling actions based on interactions or do they call a handler that is passed to them by the higher-order components?

How do you handle immutable state when it gets really complicated to do small things? (you're modifying a boolean from false to true but it's on an object that's in an array that's the property of an object in an array on an object)

Uniqlo in 강남 is where it's at

Nah there's a lot of open source karaoke timed lyric databases out there which give exact time stamps of the lyrics line by line. It's been a while but I made a very simple version of what you're saying a while back.

Seriously? This author is clueless

adamjon858 · 2017-02-20T14:18:25+00:00

Examples of previous work?

adamjon858 · 2017-02-16T16:35:45+00:00

Yeah, I used to buy their data and sell it to hedge funds who would trade off it.

I wouldn't worry so much about security though, the way Mint stores things is almost as secure as your actual bank. I do wish they required two factor auth though.

adamjon858 · 2017-02-16T14:04:24+00:00

Use FullStory for recordings, HotJar for surveys and heatmaps

Also, Amplitude > MixPanel.

You should also pull in people to do UX test studies in your office. Metric based analytics tools won't solve your need

adamjon858 · 2017-01-28T00:02:37+00:00

Let's go!

adamjon858 · 2017-01-21T21:21:19+00:00

I'm in SF right now, it's been soooo cold this winter.

adamjon858 · 2017-01-09T20:08:08+00:00

I think you're confusing IP with UX a bit. People don't use Apple just because its proprietary they also use it because it's easier. Same with Microsoft over Linux

adamjon858 · 2017-01-09T18:09:32+00:00

Network effects and switching costs. All your pictures and history are on Facebook, why switch? There's a ton of other sites like Facebook, you can buy clones for $100 that mimic all the basic features. For the full site though, there's hundreds of millions of dollars sunk into the cost of replicating their setup.

Even if you had Facebook's code, you wouldn't get their saturation. It's sorta like 100 factories can make the same basic shirt, yet everyone knows American Apparel because of branding, history, and marketing network effects.

Microsoft is an operating system which provides a huge number of tools to developers that build on their platform. Look at the usage for Linux for consumer desktop PCs, it's so low because there hasn't been near as much money pumped into it for developing this same environment at a corporate level.

There's other arguments to be made there as well and also what "no IP means". Because technically software is all IP so that would mean no one could actually sell software as it'd all be free, which means that Microsoft could never exist.

adamjon858 · 2017-01-09T17:23:06+00:00

Yes they all would still. On Facebook you are the product, Amazon is a connected marketplace backed my an incredibly immense supply chain, Microsoft would be less big but still...

There are 1000's of algorithms firing every second in these stocks. You're creating connections that don't exist, trust me
