digitalzombie··on The Zen of Erlang (2016)
Even if you write NIF C or in Rust. They can take down Erlang's BEAM VM.

> http://erlang.org/doc/tutorial/nif.html

Erlang itself shield you from actually doing stupid thing and follow the assumptions that BEAM have while running programs.

You're better off choosing a different language. Have Erlang deal with concurrency but don't have it do number crunching.

digitalzombie··on CentOS Linux 7.5 (1804) Released
IIRC it's a clone of redhat and redhat is in the business of support.

Big companies goes to red hat because they promise to support software beyond their life cycle for years. So that's that.

digitalzombie··on Rust 1.26 released
Do you know where I can find the comment about no plan for Rust 2.0? I tried googling it but I couldn't find it. Reason why I'd like to find it to have some guarantee that this is true.

Cause it sounds like a strong commitment here.

digitalzombie··on Mode Studio – Python, R and SQL Editor
I have to sign up to see this in action? No video demo or anything? I don't even know if this is a software where you download or if it's a web service cloud thing.

I think this is such a bad way to announce a product. Or lazy way.

I'll stick to Rstudio and Rodeo.

digitalzombie··on How Amazon’s Bottomless Appetite Became Corporate America’s Nightmare
I dislike how I can't get prime for just shipping without the video services.

Isn't this just bullying Netflix and other video streaming services? Not only they sell stuff online but they also have a video service. Which is fine but it's not a la carte.

It feels monopolistic. But I'm not sure if that's fair or not of a comparison but I personally don't think it's fair.

digitalzombie··on Trump administration cracks down on H-1B visa abuse
"Trump Administration Restricts H-1B Worker Visas Coveted By High Tech" is the title.

> If the way Infosys and Tata use the H-1B visa is abuse then so is how Microsoft, Google and Facebook use it.

Infosys and Tata enable companies to abuse H-1B laws. Disney use them.

Your statement also imply that Microsoft, Google, and Facebook is abusing too and no difference between Infosys and Tata. There is a small difference that I've stated but all of them are abusing it.

The point of contention is not that the Indians are stealing our job. The point is the people who are using H-1B visa are unable to negotiate wages which depresses their American counterpart wages.

digitalzombie··on Lift Weights, Eat More Protein, Especially If You’re Over 40
Make it a habit. Start out small and stick to it for 60-90 days or something. Go at least 3 times a week and do 3-4 exercises and stick at it.
digitalzombie··on California does not have the highest poverty rate in the USA
That's your interpretation of the article. I don't believe that's how the article was written.

Author acknowledge the high housing cost but states that the metric that was used only account for a few things and it ignore other metrics which can skew it towards a certain argument.

Author also stated that the other person lied about how large state employment for California is. Author actually normalize/standardize it per capital instead of a having stating this is a large number.

You and the article can argue whatever yall want but it's just an opinion until yall do factor analysis or some sort of algorithm to figure out what's the right combination of metric is.

digitalzombie··on AI in drug discovery is overhyped: examples from AstraZeneca, Harvard, Stanford
Do you have a source for that? I'm super interested into reading more.

I had to do Tox21 I was using Bayesian Network for drug toxicity at the FDA we used the DILI database.

digitalzombie··on Ask HN: How much do you make at Facebook/Amazon/Apple/Netflix/Google/Microsoft?
I liked the comment system we were able to have a discussion.

While the PR guy was shady, realizing other people having the same experience via rebuttal and affirming my comment via their experiences seem much better.

I usually like having a dialogue/discussion. Glassdoor is where you can give anonymous reviews, mind as well have people annoymously have a discussion about said company.

digitalzombie··on Ask HN: How much do you make at Facebook/Amazon/Apple/Netflix/Google/Microsoft?
I had a bad experience with glassdoor.

I wrote about my bad experience at one of the company I interned for. Some PR from the company comment on my review, I knew the PR guy cuz he goes around doing it to other reviews there and create fake reviews.

Anyway, I call him out on it said he's using ad hominem for one of his tactic in the comment. Other users comment and back my report up.

After a few week glassdoor deleted my comment and the comments that back me up, they left the PR guy comment up. I wish I could have screen shot it.

Eventually they did away with the comment system.

I don't trust them at all.

There are aggregate surveys from O'Reily and stackoverflow. I think it's pretty decent. O'Reily doesn't give raw data for their data science survey so I couldn't do any survey analysis to confirm it but they release their linear regression model.

digitalzombie··on A personal ode to the Boeing 747
> Now pretty much anyone in the middle classes can afford it.

https://www.npr.org/2016/07/07/484941939/a-portrait-of-ameri...

Quote from NPR "Since economists first began keeping track in 1970, every decade has ended with fewer people in the middle class than at the start. And 2015 was the first year on record when Americans in the middle-income bracket did not make up the majority of the country"

Middle class can afford it now you say and yet the middle class is shrinking and the poor class is growing. Are you ignoring the inequality and shrinking of the middle class when you make such a statement?

> deregulation and consolidation

If there were many air lines and now they are consolidated to fewer is this not anti competition? Or is the market going to fix it by less regulation?

Here's the graph from the 1970s to 2010s: http://psf_blog.s3.amazonaws.com/blog/wp-content/uploads/201...

Do you believe in the concept of natural monopoly Ihttps://en.wikipedia.org/wiki/Natural_monopoly)? If so what's your solution to that?

edit/update:

Something in the back of my mind was skeptical about your claim of airflight being cheaper without source. It seems more like you're making a statement base on feeling.

I googled:

Note here's one article that stated that it went up on average by a bit adjusting for inflation:

http://www.travelandleisure.com/travel-tips/airlines-airport...

Another article argued that the statistics ignore the outlandish carry baggage checkin that in fact it is more costly today to fly than it is in the 70s.

digitalzombie··on Statistical Computing for Scientists and Engineers
As a statistician I will try to defend my field.

Statistic is a field to represent the noise and uncertainty by quantifying it.

It is unclear to you or lacking in brutal honesty but the honest truth is the world is not perfect. If Kobe can shoot 100% of the free throw then you can perfectly model it without statistic but sometime he misses and because of that we need statistic to take into account the fact that while we expect him to make freethrows sometime he miss his shot. Without statistic you cannot take into account the sometime Kobe miss shot.

It is also the field that define in definite what significant means. Statistically significant is the difference between this med really works versus it's a placebo/not sig enough.

Another concrete example of not perfect is data. Either collection of data (missing data, measurement, etc..) is not perfect and statistic helps. You can do ordinary least square without caring about statistic but finding outliers in the data, fixing the missing data, etc.. require statistic iirc.

digitalzombie··on Statistical Computing for Scientists and Engineers
> it's just not trying to be a intro course.

> It's not expected that this is the first time someone in the course has come across most of the concepts and methods.

It is just cramming at least 4-5 stats classes in there that's all.

Unless you get those right combination it'll be your first time anyway. There are multivariate stat, 2 courses of Bayesian ( 1 tradition and 1 nonparametric), 1 course of comp stat, and whatever the heck else I've haven't encounter.

Bayesian isn't even taught in my grad program at all. I had 2 months to learn Bayesian.

I disagree with the not expected to be first time and maaaaybe it's just to get your feet wet.

Considering the stuff the professor is going over it seem more sink or swim.

digitalzombie··on India’s IT industry laid off more than 56k employees this year
> Cut the crap. India is a country of 1.3 billion people, don't peddle bullshit stereotypes. Not working hard doesn't come from the culture; it's quite the opposite if anything.

Actually, I know this is anecdote but my buddy was an manager type position moved up from software and he had to deal with Indians. He had to go over cultural slides to how to deal with Indians and the slide explicitly talk about their world ethnics and how their culture view time.

The time slide was super interesting and the few thing I recall from it. It was talking about setting time line for the offshore team. And when they say they will have it done, it can mean anything, and that you have to have them to explicitly state a real date.

I'm not trying to shoot ya down or anything, just wanted to point out another experience in culture. The slides he showed me was suppose to be on the downlow too >___<. But the whole thing is about how to manage Indian programmers and many aspect of it was dealing with culture or how culture affects their actions.

digitalzombie··on India’s IT industry laid off more than 56k employees this year
Only thing I can think of is a ledger. If it isn't about currency then it is some sort of ledger.
digitalzombie··on Vietnam Deploys Cyber Warriors to Fight ‘Wrongful Views'
On that same thread, Cisco built the Chinese Golden Shield which is what now is refer to the great chinese firewall iirc.
digitalzombie··on Harvey – An effort to provide a modern, distributed, 64-bit operating system
Nice to see all these new OS coming out.

I'm personally rooting for HURD (https://www.gnu.org/software/hurd/hurd.html) and Barrelfish(http://www.barrelfish.org/)

digitalzombie··on Ask HN: How can I learn computer security?
> Is there any link between data science and cyber security?

There's... a company around LA area that does cyber and data science. I would think they apply data science to logs and such to figure out abnormality. Likewise if you count email spam detection as a cyber security thing.

For cyber security, take Network+ or just grab a Network+ book. I believe that's where you should start first in cyber security.

digitalzombie··on Firefox is on a slippery slope
> many users use firefox for ideological reasons, even when Chrome is/was technically superior.

I was here since Netscape, AOL, prodigy, and Mozilla save me from the hell of IE.

I didn't move to Chrome not cause Firefox was inferior. It's because firefox can handle 100s of tabs and Chrome crash when I have a fraction of that.

You're right on the ideology but it also can handle 100s tabs.

digitalzombie··on Languages for online betting: an investigation of Go, Erlang, and Elixir
Pony isn't even version 1 yet iirc and instable API.

I mean would you like to bet on that stack on top of your betting platform? >___>

Pony promise great things and the language have a proof and all that but it still needs to be battle tested and get to some sort of stability.

https://www.ponylang.org/discover/#what-is-pony (under why not pony section, API unstable)

The degree of tech hype and adoption of bleeding edge is crazy. The thought of programmers just betting on these thing without thoughts on the schmuck who would inherit these technical debt still boggle my mind.

digitalzombie··on Philadelphia write-in candidate: I won with one vote
It exist but it's not statistically significant enough. It certainly doesn't warrant the huge drawbacks of disinfranchising voters.
digitalzombie··on What MongoDB got right (2015)
What? Are you talking about like primary key?

Cassandra have this, any hash database should have some sort of unique concept or key, and IIRC graph database all node should be unique.

I didn't realize this was a rare thing in NoSQL world.

digitalzombie··on A guide to great things still made in the U.S.A
They have randolph engineering (great sunglasses) but not bravestarselvage.com ?

It's a good selvage denim company.

digitalzombie··on Tesla Roadster
Ford sold Jaguar and Land Rover to Tata motors during the recession. They also sold Aston Martin and Volvo.

> edit: Ford didn't start Jaguar.

I don't even know what this even mean. Nor do I understand what the original comment of yours mean. It doesn't make any sense and it doesn't seem like you are well verse with cars or automakers at all...

digitalzombie··on Tesla Roadster
> Does this mean that Tesla is pivoting from their attempt to produce a medium-priced car in quantity and going back to hand-building high-end cars?

It's a halo car...

Car companies build halo car to get consumers attention to their brand and to sell other models.

Nissan didn't have to build the GT-R R35 but it did because it's a halo car.

Another example is Toyota LFA.

digitalzombie··on Ask HN: What tech were you convinced would take the world by storm but didn't?
Those VR glasses for augmented reality, the google glasses... but nope.
digitalzombie··on Ask HN: What are you learning right now?
I googled up CAF after you mentioned this. It looks interesting but looks too new for me (seeing the version number).

Also how does it compare to Erlang? The website mentions state of the art scheduling I'd like to see that claim against Erlang's BEAM vm.

digitalzombie··on Ask HN: What are you learning right now?
1. Survey Analysis - class

2. Survival Analysis- class

3. GLM- class

4. Tree base classification algorithm (currently reading QUEST) - Thesis

5. Scientific C++ - Thesis

6. Folklorico Dance

7. Salsa (Not doing well... =/)

digitalzombie··on Show HN: Erlang REST framework
It's Prolog inspired. It's weird because it never took off like C/C++ like languages.

The language syntax is small enough that I believe it'll take a short time to learn and get use to the syntax versus other languages.
