alrex021··on Grok: Searching X for "From:Elonmusk (Israel or Palestine or Hamas or Gaza)"
Truth-seeking, next level hilarious.

alrex021··on Language models can explain neurons in language models
IMO this is akin to how scientists developed thermodynamics to comprehend steam engines. Except now, AI could be on the forefront of forming conjectures and explanatory theories!
alrex021··on Pfizer 91% effective in updated data, protective against South African variant
Do you refer to SARS-CoV-2 as the Chinese virus?

The actual name for the variant in question is 501.V2.

alrex021··on Pfizer 91% effective in updated data, protective against South African variant
Hilarious that they still label it as a country variant, as if the variant carries a genetic “country” code that determines the origin. Plain stupidity.

[Edit] To elaborate since there is so much negativity to my original comment. There is no absolute proof that the variant originated in South Africa, so calling it by a country’s name is an insult to human intelligence. We refer to the virus as the Coronavirus and not the Chinese virus. Why should the variant be any different? (This variant being actually called 501.V2)

Is that you Elon? ;-)
alrex021··on Farewell, Google Maps
A 20x jump on the monthly charge, especially in lower margin business, will hurt whichever way you look at it, IMHO.
alrex021··on Farewell, Google Maps
In our own experience, we pleaded the fact that those dollar figures are just beyond workable if you consider the fact that we come from a developing country and we're faced with ~20x jump. I.e. it heavily messes with the unit economics. The Google representative actually laughed in our face (via Hangout).
alrex021··on The Game Theory of Anonymous Donations
Good question. From a game theoretic perspective, agents (players) are assumed to be self-interested in a non-cooperative setting if I recall. Maybe someone can comment on this a bit further.
alrex021··on Deco Software – React Native IDE
We've got so many beta requests, we can't process them fast enough. So, just refer as many people as you can, and we'll bump you up somewhere in the "waiting list". Ingenious. ;-)

I heard that this game also comes with a free oneway ticket to Australia.
alrex021··on Everything about Java 8
Interfaces with the addition of default methods, in contrast to abstract classes, provide the inheritance of behaviour (but not state) from multiple sources.
alrex021··on Cloud Haskell on Raspberry Pi
In the current form, yes HaLVM requires Xen, therefore Xen on ARM support would be required too.

Xen on ARM [1] support is ongoing and from what I can tell, the repository [2] is flagged as unstable therefore certainly still requiring work.

[Edit] RaspberryPi has an ARMv6 CPU. The Xen site reads: "The Xen ARM Project, led by Samsung, is responsible for the direct port of the Xen hypervisor to the ARM processor. So far the focus of the project has been to use Xen Paravirtualization (PV) for a range of processors (ARM v5 - v7).".

This means that it should cover ARMv6 of course. As for the status, I have no idea.

alrex021··on Cloud Haskell on Raspberry Pi
That's a really interesting idea considering the limited resources of the device.

Thank's for the suggestion; I'll check out the HaLVM site once it comes back up.

alrex021··on Running Haskell on Raspberry Pi
One way it seems is to compile via QEMU [1] to target other architectures. I haven't tried it myself yet though.

"When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC)."

If that is the price, it will be the lowest price for a FF 35mm camera by about $500.
alrex021··on Light Table's Numbers, And What's Happening Next
Not to sure if anyone has mentioned this yet. If you run light table as client(browser)/server model, then effectively your sever could run in a cloud and your session would be reachable from any browser no matter where and what computer or smart phone/tablet you are on.

With things like ClojureScript and Meteor, this is very achievable today and a definite game changer. Exiting times we live in.

[edit] Oh and good luck Chris and the team.

alrex021··on Compiling Clojure to JavaScript, pt. 3 – The Himera Model
I like this quote:

  "Compiler as service is the new black."
Himera can take ClojureScript and return AST in the form of embedded Clojure maps, which is very cool!

Animal Liberation by Peter Singer

Peter Singer introduced and popularized the term "speciesism" in the book that is often referred to as the bible of the animal rights movement.

alrex021··on Java 7 Fork-Join Calamity
My personal disappointment is the lack of expressiveness.

Here is a C# LINQ example:

  using System.Linq;
  files.AsParallel().ForAll(file => ProcessXML(file));
To achieve something similar in Java 7, one could start on perhaps with improving the java.util.Collection interface, or appropriate abstract children, by introducing the asParallel method that the Collection implementations could implement. One obvious problem I see is the lack of lambda support in Java 7, so one would have to pass an anonymous class into forXXX(..) instead which is a bit more clunky.

alrex021··on Ask HN: Anyone using Haskell in production?
Well-Typed, a Haskell consultancy, seems to do quite a bit of work exclusively in Haskell.

For instance, they have developed an air traffic analysis tool for NATS[1] which they briefly blogged[2] about.

alrex021··on Clojurize the Data, Not the Database
Correct me if I'm wrong here but isn't that the purpose of the adapter implementations to also hold the different dialect and/or datastore specific optimizations?

[edit] OT to this thread: didn't clojure-dbm have some similar ideas to Clojurize? I remember forking it from your github repository early last year some time and doing some cool stuff with it.

alrex021··on Clojurize the Data, Not the Database
> While it's nice to say your program to store to any kind of datastore, it's much more practical to have it optimized for the kind that's best for it.

I think this is very arguable. For the cases where you want to do some query optimization, thats what the Clojurize protocol's prompt function is intended for.

  (prompt
    [adapter expression]
    "Execute a native database expression")
alrex021··on Book review: Land of Lisp
Clozure[1], formally know as OpenMCL, is a great CL implementation for Mac and other popular platforms.

I've been running Clozure and Aquamacs[2] editor for the past two years and I can only say good things about both.

Firstly, congratulations on completing the book.

Will this book be available for Kindle by any chance?

Good point. I'll update the title.
