exacube··on LinkedIn CEO Jeff Weiner Gives $14M in Stock to Employees
but the loss (from the stock tanking) would be the same regardless of how many employees had options though, no?
exacube··on Ask HN: How to handle 50GB of transaction data each day? (200GB during peak)
If your data is growing at this rate (and you plan to keep this data around), you'd want a distributed database that can scale to terabytes. But it might be overkill if you dont care for data consistency (i.e., you dont need to read it "right away" after you do a write):

If you just want reports (and are okay getting them in the matter of minutes), then you can continue storing them in flat files and using apache HIVE/PIG-equivalent software (or whatever equivalent is hot right now, im out of date on this class of software).

If you want a really good out-of-box solution for storage + data processing, google cloud products might be a really good bet.

exacube··on Google to Fold Chrome Operating System into Android
or, Android is coming (if it hasn't already) to x86?

how well does a full-fledged Chrome on ARM perform? Does it even exist?

exacube··on Microsoft Unveils Its Arrow Launcher for Android
I don't think it's possible to replace the lock screen in a native way. All "custom lockscreens" in existence today are basically hacks -- you will notice flickers when the lock screen activity is initialized, for example.

It's necessarily not customizable for some security reasons (unlock code, etc.)

exacube··on Do you know how much your computer can do in a second?
Author makes a comment that "If we just run /bin/true, we can do 500 of them in a second" -- this is very platform dependent -- i think Linux' process creation is supposed to be 1-2 orders of magnitude faster than Windows, for example (i don't have the exact numbers though).
exacube··on 23andMe meets FDA standards, adds back wellness reports
why, what happened?
exacube··on Just Say No to Facebook's Internet.org, Says Inventor of World Wide Web
I don't know if this is practically true for a lot of these countries. In a lot of these countries, a vast majority of the population doesn't have easy education, and are often poor. Countries like India have a much better percentage (but still small) of the population that can afford the internet, that ISPs are incentivized to grow and expand. Countries like Zambia -- not so much (I don't actually know if internet.org is in Zambia). I don't know that a small business in Zambia has the capital to expand considering how many people can afford it.
exacube··on Just Say No to Facebook's Internet.org, Says Inventor of World Wide Web
Why are people so insistent that Facebook's Internet.org is a bad thing? Is no internet really better than limited internet? These people have almost no internet right now. A lot of these countries can now use Google and Wikipedia. It's either total freedom for free, or no freedom at all?
exacube··on New Chromecast 2015
You can cast a chrome tab, so it actually supports streaming. They're just protocols, why do you need to support Miracast for it to work on Windows?
exacube··on A Simple Proof That Pi Is Irrational
I feel really bad when I read stuff like this and don't understand, especially when it's titled "Simple" (granted I didn't spend more than 5 minutes trying to following the proof)
exacube··on How much water is there on the Earth?
Can someone make a comment on the sustainability of our current water consumption, in terms of the US, other parts of the world, and the world itself?

If we are not living sustainably, should we expect more investment across the world on things like desalination plants (I understand that desalination is really energy-expensive currently, but will that change by much?)

exacube··on With $100M in Funding, Carbon3D Will Make 3D Manufacturing a Reality
examples / links?
exacube··on Microsoft Expands Its Parental Leave, Bolsters Paid Time Off And 401k Matching
> However, giving a benefit to people who have kids without giving that same benefit to people without kids is not that different from the company saying that they want their employees to have kids. /want/ their employees to have kids means that they desire it to some degree. I am sure MS doesn't desire it, but rather indifferent. But they do desire to be a more humanitarian company and want their employees to be happier.

> Why shouldn't we also keep people without kids happy? Everyone deserves time to pursue passions outside of work. Some people are passionate about their families. Are you trying to say that because people with children have parental leave, people without children should have equivalent leaves too? That sounds a little ridiculous to me.

exacube··on Netflix Announces Its New ‘Unlimited’ Maternity and Paternity Leave Program
In contrast, I hear Amazon has no paternity leave (or maybe its like 2 days or something?)
exacube··on Amazon Is Now Worth More Than Wal-Mart
Isn't this true for all companies? And if so, why is this meaningful in particular for Amazon
exacube··on What if anything have we learned from C++? [video]
by plain old, i think infradig was implying that C was plain and old compared to C++, and not about an older standard of C.
exacube··on DigitalOcean Raises $83M in Series B Funding
Why?
exacube··on Project Fi Review: Cell Service from Google
The craziest part of Project Fi is that phone calls and network connections do not drop at all while it is switching carriers/WIFI underneath -- there is a lot of low-level networking magic happening here, and the crux of this tech. I hope some day Google will release some code or white paper on this.

- I'd love to read a more indepth analysis about how /well/ this interface/service provider-switching works. - I want to know if the signal/coverage is comparable or better than Verizon (which IMO has the best quality+coverage in the parts of the US that I've travelled; all over the west coast & hawaii).

exacube··on Orange: A simple systems programming language
What are the pros of leaving out the type identifier when declaring a generic type? I understand that it's viable to not provide some "Type" identifier to denote a generic type, but I feel like it's better to have it for clarity. What happens when you have a function that accepts two kinds of generic types? This inconsistency doesn't seem worth it to me
exacube··on Ask HN: How do you familiarize yourself with a new codebase?
One idea is to use Linux's `perf` to sample stack traces, as the program is running, over a minute or so and see where the code flows.
exacube··on Why do you want libc to be 5 times slower than other libraries?
This post is really old (2008) and probably already resolved. Here is the jist of the optimization that this person provides:

memory and string functions in libc have poor performance because you are not using XMM registers and you have no efficient way of dealing with unaligned data. The most efficient way of copying data when source and destination have different alignments is to read aligned into XMM registers; shift and combine consecutive reads so that they fit the alignment of the destination; then write aligned

exacube··on Rust 1.1 Stable, the Community Subteam, and RustCamp
Thank you, you're doing a great job!!
exacube··on Rust 1.1 Stable, the Community Subteam, and RustCamp
I'm happy things are moving along, but I would still like to see the documentation be more polished. I still don't know how to write a task queue (ie queue of closures) that executors can concurrently read and run from.

I don't feel like the docs empower me enough to write multi threaded code comfortably without the borrow checker spitting at me. Is it just me, or does anyone else feel this way?

exacube··on Ark – A modern systems programming language
wait, you don't like putting your List<> inside your Arc<> inside your Cell<> ?? ;)
exacube··on How Adobe keeps key employees from quitting
I would actually think otherwise -- with no formal documentation of poor performance, they'll have a much harder time justifying a layoff/firing if they are sued for discrimination or something.
exacube··on Google has quietly launched a GitHub competitor
This article is just click bait.

Pretty sure this product is just so you can store your code/repo for your project using Google's cloud services. It's part of a whole for their cloud offering.

exacube··on We need to rethink employee compensation
Every level 5 (senior) engineer at Google and Facebook converge around $250k in total yearly income (probably more for facebook recently since their stock tripled in the past year).
exacube··on Introducing the Famous Framework
For a UI framework, show me a pretty demo with some example snippet code next to it and I will read on. Otherwise, I'm not motivated -- this is not the way you want people to read about your UI framework.
exacube··on Happy 10th birthday to us
If my fingers were to equal Google's $375B market cap, each of my finger is worth $37.5B.
exacube··on Linode turns 12, transitions from Xen to KVM
Thanks for the clarification!
