jtmarmon··on Announcing TypeScript 2.1
Can someone comment on the difference in reliability between using typescript and a natively statically typed language like haskell or scala? Is there any? Or is the type safety really as good when you use ts
jtmarmon··on Amazon Go
i believe this is it too, mainly because of their mentions of machine learning and computer vision in the post.
jtmarmon··on Ask HN: What “missing” technical solution(s) do you wish existed?
did you switch to java for work reasons or because you wanted to?
jtmarmon··on Ask HN: What “missing” technical solution(s) do you wish existed?
haskell on rails. the amazing static typing, binary compilation, etc of haskell, with a large ecosystem and monolith framework (like rails) behind it. haskell's community's focus on challenging, technical, scientific or mathematical problems has left normal web developers plainly not using it. but as our rails codebase has grown, it's hard to identify refactoring issues outside of obessive and overlapping unit tests.

i think Java actually comes closest to what I want here but unfortunately it's pretty hard to get past all the cruft the ecosystem has accrued over the years, plus it's java and marketing that as a company/developer sucks. also java is missing some expressiveness of haskells TS

jtmarmon··on Finding the genre of a song with Deep Learning
i'm not super familiar with deep learning so forgive me if i'm missing some nuance, but what's the purpose of writing/reading to/from images? seems like it would add a ton of processing time. could the CNN not just read from a 50 item array of tuples representing the data from the 20ms slice?
jtmarmon··on Tell HN: Riseup.net fails to update canary; fingerprints deleted without notice
Perhaps I'm doing this wrong but when I try to verify the gpg signature I get

jtmarmon··on George Hotz cancels his Tesla Autopilot-like ‘comma one’
i understand where you're coming from, but there is a counter argument to what you're saying, which is that although there may be some dangers to things like the comma one and tesla autopilot, their release may save more lives than they edanger, having a net positive to humans. humans are pretty bad at driving
jtmarmon··on DDoS Attack Against Dyn Managed DNS
removed the github plugin, reloaded zsh and happened again 5 min later. I believe it has to do with slack, because the issue resolved itself after closing. maybe slack got pwned and all slack users are being used as part of the botnet lol

jtmarmon··on DDoS Attack Against Dyn Managed DNS
Semi related: I noticed this incident right when it began, but not because I was trying to access a website. This started happening to me: http://imgur.com/PPlaY5o

Then when I went to push to github out of fear my computer was about to soil itself, that failed too, and I noticed the outage.

Does anyone know if the above errors could be related to the outage? I'm using vim inside tmux with zsh as my shell. Maybe zsh does some kind of communication with gh while running?

I restarted my computer and it's still happening

jtmarmon··on DDoS Attack Against Dyn Managed DNS
I'm updating a list of confirmed outages as I see them here https://news.ycombinator.com/item?id=12759520

So far twitter, etsy, soundcloud, spotify, github, pagerduty...crazy that this can even happen

jtmarmon··on Massive Dyn DNS outage
not very useful to post a status update on a site that is experiencing the same issues with the same DNS provider.

maybe post a github gist? oh wait...

jtmarmon··on Ask HN: Is Twitter DNS resolving for you?

jtmarmon··on Vim for Humans
the problem with learning vim is that it's like learning to bike by biking to work. most people use vim when they code, and they code at work, so using vim is directly in the way of getting any productive work done.

i was just one of the ones stupid enough to waste two weeks of productivity to learn a new tool lol

jtmarmon··on SWAPDB Redis command
ahh got it! thanks :)
jtmarmon··on SWAPDB Redis command
Very interesting feature. Question: is it not standard protocol to add a test with a new feature like this?
jtmarmon··on Fat-fueled brain: unnatural or advantageous?
tried it, tastes like garbage in my opinion. tried like 3 flavors
jtmarmon··on Our First 50,000 Stars
maybe this is just me but what even is that t-shirt? it looks like two unrelated images thrown on top of one-another in photoshop
jtmarmon··on How the Sugar Industry Shifted Blame to Fat
not to mention most fruits have been selectively bred/genetically engineered to have much higher sugar content than they did when we evolved to eat them seasonally
jtmarmon··on Machine Learning and Ketosis
you're correct; had my terms jumbled. edited my comment for correctness.
jtmarmon··on Machine Learning and Ketosis
100%. i take pills for the sodium and magnesium (they usually have potassium too but usually not enough). and avocados are a staple when it comes to potassium
jtmarmon··on Machine Learning and Ketosis
Most people find that their alertness and focus improve significantly on keto.

The trick is that

a) it takes quite a while for your body to get adjusted to ketosis. 6 months to fully adjust, but the primary adjustment will take at 2-4 weeks for most people

b) during this adjustment period, you'll usually feel like shit. since you're running empty on the fuel your body is used to. but many people cheat, or accidentally ingest too many carbohydrates, persistently keeping their body out of ketosis and ensuring they feel terrible endlessly and blame keto for it.

jtmarmon··on Machine Learning and Ketosis
This situation has been highly debated among the keto science community. I call it a situation and not a study because they're publishing preliminary results for a pilot study. Hardly conclusive.

jtmarmon··on Machine Learning and Ketosis
I don't contest that ketone level affects weightloss, but just to be clear, ketone pee strips don't tell you anything about your "ketone levels". They tell you the concentration of ketones expelled in your urine, which varies by a lot of things, like time of day and hydration levels.

Precision Xtra test strips will give you a far more precise and accurate measure of ketones in your blood and if you wanted to do anything quantitative like in this case study, you'd want to use those.

jtmarmon··on Show HN: PlateJoy (YC S15) – Algorithmic meal planner with integrated delivery
This is really insanely awesome. I've been on keto for years and have always wanted a service like this. A "blueapron" type of service would've been perfect for me, but because they pick the meals, it would never work for keto.
jtmarmon··on RethinkDB 2.1.5 performance and scalability
Has the live query stuff performed well? i.e. subscribing to some arbitrary db query for new records?
jtmarmon··on It’s cheaper to build multiple native applications than one responsive web app
It might be true that it's a pain in the ass to write a responsive web app, but that doesn't mean it's not worth it. Users are unlikely to download a mobile app just because you say so.

Of course YMMV. If you have control over what the user does like some kind of internal enterprise app then go for it.

jtmarmon··on Show HN: Real Time Users – Add a real-time user counter to your site
i find it hard to believe google analytics is "not well known enough"...does this do something different?
jtmarmon··on HTTPie: a CLI, cURL-like tool for humans
there is an http cli already. it's included in like every OS ever...it's called curl. httpie is just more user friendly
jtmarmon··on This is not a place of honor
> (a) We have all become very marker-prone, but shouldn't we nevertheless admit that, in the end, despite all we try to do, the most effective "marker" for any intruders will be a relatively limited amount of sickness and death caused by the radioactive waste? In other words, it is largely a self-correcting process if anyone intrudes without appropriate precautions, and it seems unlikely that intrusion on such buried waste would lead to large-scale disasters. An analysis of the likely number of deaths over 10,000 years due to inadvertent intrusion should be conducted. This cost should be weighted against that of the marker system.

Wow. reminds me of the ford pinto case: http://users.wfu.edu/palmitar/Law&Valuation/Papers/1999/Legg...
