jtmarmon··on Snapchat Passes Twitter in Daily Usage
How exactly do you know it's not accurate? If you're saying that because of Google trends, keep in mind that Twitter is a website, Snapchat is not. Lots of people still google "Twitter" to get to the homepage. Pretty much no one would be googling snapchat...
jtmarmon··on A Facebook Sixth Sense
is this really a contrarian opinion? i feel like this is a pretty obvious fact that it's easier to read network requests to scrape a website than parsing html
jtmarmon··on Snapchat raised $1.8B in a Series F round
"If a snapchat clone came out tomorrow, snapchat wouldn't be as sticky"

there have been plenty. facebook even launched one

jtmarmon··on Show HN: Automatic private time tracking for OS X
thanks! that's easy enough :D
jtmarmon··on Show HN: Automatic private time tracking for OS X
this is super awesome. I've been using rescuetime for around two years, and although it's worked great I'd love to see more feature progress. Also there's no 2FA support which is quite scary for something with such sensitive data.

I love your dock icon as well. I was trying to build a custom version of that but for my tmux line, but rescuetime's API doesn't provide realtime info.

Will you open up some APIs for the data? I'd love to be able to do my own analysis and build my own tools. I'd also like to backup the data to s3

jtmarmon··on Rails 5.0.0.rc1
throwing shit together is insanely fast. i mean insanely. once i had a friend who was asking me for a time estimate on building a backend for his iOS app (mostly crud with a couple search routes) and i just did it for him in thirty minutes.
jtmarmon··on Ask HN: Is Golang mature enough for FinTech startups?
you'd have to explain more about what you're doing, but i'm sure go is fine. i'm also sure rails is fine.

i can't speak for the first two points, but those seem simple enough to avoid with tests, really. most issues are.

the third issue is something you have to decide on. i'm sure the tooling around go is much better than it was three years ago, but you're not going to have everything in a pretty package like you do rails.

honestly the choice is probably inconsequential, unless you have some actual reason why the language choice matters for your application (which it almost always doesn't).

also if you're in fintech and doing bitcoin, i've heard the node ecosystem has the most BTC support, so that's a consideration

jtmarmon··on Warcraft fans' fury at Blizzard over server closure
open source means the source is open. that's all it means. free software is what you're referring to and it's something entirely different
jtmarmon··on Mixpanel: Introducing JQL, a query language to analyze and learn from data
first thing i thought of too. even if they don't mind it's kinda a weird naming choice

jtmarmon··on Ask HN: Is the Thiel Fellowship worth it?
don't apply to things because you might get rejected from them is certainly good life advice
jtmarmon··on Ask HN: Is the Thiel Fellowship worth it?
Thiel Fellow here. The question is not whether or not you should take it, it's whether or not you should drop out.

I had already dropped out when I took it so it was a no brainer for me. If you've already dropped out or decided to I don't even know why you're asking - at worst it's free money.

If you're asking whether or not you should drop out, that's a pretty opinionated thing and depends entirely on your circumstances, but I'd recommend you go for it (fellowship or not). As morgante said, you can always go back to college. 10 years from now sillicon valley might not be so friendly to us tadpoles

does anyone know of other services which can deliver in around that 10 minute mark?
jtmarmon··on How cancer cells fuel their growth
Keto is not low carb, high protein. It's high fat, low carb, moderate protein. On keto you eat the standard recommended amount of protein (depending on your athleticism, it'll be around .69-1.2g per lb of LBM). Most of your calories come from fat.

My breakfast this morning was coffee with butter and MCT oil

jtmarmon··on React Makes You Sad?
That's actually not what it's saying. It says if you're not in production and you are using a bundler, get rid of it. If you are in production and not using a bundler, start using it.

If you're in production using it and still sad, or if you're not in production and not using it and still sad, move to the next step.

jtmarmon··on What 5G Will Mean for You
> Driverless cars with extremely fast response times

Seems like relying on low network latency for critical safety features is designing a fundamentally flawed system.

Is this really how driverless cars are being made or is the author just pulling things from his ass

jtmarmon··on AI generated music to improve focus, relaxation and sleep
been using this for months and enjoying it a lot while hacking. i definitely get into flow more quickly and stay in it more easily
jtmarmon··on Kemal: Fast, simple web framework for Crystal
looks nice and awesome benchmarks...checkout the memory comparison in node vs kemal: http://kemalcr.com/docs/websockets/

Crystal (Kemal) CPU 1.85 Memory 11.2 MB

Node.js (ws) CPU 38.95 Memory 906.3 MB

impressive

jtmarmon··on DRYing Elixir Tests with Macros
If a macro used for a test suite is substantial enough and used often I'd say it's worth testing
jtmarmon··on Analysis of Software Architectures
You can do a cross service join in a single request. Combine that with good caching and a normalized architecture is (almost) as performant as a demoralized one.

Check out https://github.com/facebook/dataloader

We use it to do cross service joins in the form of bulk requests in a very transparent way.

jtmarmon··on An Easy Way to Learn Hard Stuff
I think videos are really helpful for absolute beginners. Technical blog posts are usually really dizzying if you haven't the slightest clue what's going on
jtmarmon··on Slackcat – Pipe command output to Slack from your terminal
awesome tool. definitely could've used this a few times. it doesn't seem there's a way i can DM users rather than posting to groups. is this functionality possible and/or planned?
jtmarmon··on Stop Comparing JSON and XML
Agreed, they're not convenient for arbitrary attributes. I think where they shine are using a well defined preset of attributes to define structure.

Regarding the legacy thing, I think it's both. If you look at a lot of new tooling coming out that has to store UI state, people are still using XML

jtmarmon··on Stop Comparing JSON and XML
This article is pretty garbage. compares almost nothing about xml and instead compares the tooling around xml giving no thought to the tooling around json.

instead, let me give you my unsolicited opinion:

if you need to represent both the structure of your data and characteristics within that structure, xml is great because attributes are a really good way to do that. there's a reason most UIs are represented as XML.

if your data is just - well, data - use json. or better yet use edn

jtmarmon··on Amazon Bought Me for $100 a Year
Only true if those purchases would've only been made on amazon prime. The author said he replaced target with amazon prime, so it would make sense his spending on AP shoots up. In reality it's hard to say for sure.
jtmarmon··on The quantum computing era is coming fast
can someone explain why it can't run Shor's? I thought Shor's was an algorithm designed to be run on QC, and D-Wave is a QC. What makes D-Wave different from the intended hardware?
