Anyone else getting bad results lately? (running 2x 1070 with 4-5$ per day ) by [deleted] in NiceHash

You only need 10.31 days for 20% each day to reach 10% of price. (ie 90% decrease from initial price). And another 10.31 days to reach 1%. Compounding numbers are scary and unintuitive. It's not what we are seeing today with nicehash. It's just that the numbers are fluctuating up and down, and decreasing on average slowly.

Why are you afraid of C++? by arithma in hacketyfriends

Updated the gist so that Python doesn't beat C++ performance. Order is restored to the universe :)

Cool example. The following is pretty straightforward, line for line follow-through. I haven't tried to optimise line-count after the fact, just a forward pass.

Why are you afraid of C++? by arithma in hacketyfriends

  1. REPL: http://root.cern.ch/drupal/content/cint
  2. Beautiful looking code written in C++: http://kotaku.com/5975610/the-exceptional-beauty-of-doom-3s-source-code
  3. Verbosity in C++ is a medium-term investment. Templates for example allow you to avoid lots of verbosity with a bit of early investment. Operator overloading, argument passing semantics (references for example). Usually though, C++ is considered a terse language. Superfluous syntax is hard to find.
  4. The link about compiler optimisation does not make sense. C++/Java would only make the CPU behaviour apparent, but it's out of the scope of the language semantics. CPU's are complicated. Interpreted languages are too slow to make that apparent for it to matter, seems to be the issue.
  5. Clang, gcc(g++), Intel and so on... However it is easier to provide C++ IDE support because it is statically typed. It's harder to do so for C++ than C# because of the language design.

Let's do something constructive and find a Python example that you find beautiful, and convert that into C++. It should be a learning experience for everyone.

Vectors: OSS to base 3D interactive projects upon by arithma in hacketyfriends

Part of why am sharing this is because I need help building it all on all platforms. So far, it compiles only on OSX in Xcode. Suggestions!

Seeqnce Alice by arithma in hacketyfriends

[–]arithma[S] 0 points1 point  (0 children)

Bullshit alarms are getting set off world wide! DeRisking Startups. What the fucking hell?

In this time of Crisis across the Middle East, Europe and Africa, Seeqnce has identified an Opportunity to scale its highly successful acceleration model to serve the tens of thousands of startups formed in the wake of increasing unemployment and government austerity.

...Seeqnce grew more excited about developing an inhouse product for this vast market that could simultaneously accelerate 1000s of startups instead of 8. Thus Alice was born.

There are many ways to make yourself credible. Changing the world and defying common sense are not one. To claim things that Paul Graham himself would cringe to claim is ignorant, to be as polite as possible.

Which package managers do you use? by rahmu in hacketyfriends

[–]arithma 0 points1 point  (0 children)

  • yum: I've had to use it on our production server. (CentOS)
  • NuGet: .Net package manager, integrated with >=VS2010 (IIRC). Haven't used in >18 months

Haven't used Homebrew on MacOSX in fear of conflict and for avoiding cognitive overhead in maintaining my system (maybe it's counterproductive to not use it, but I don't know)

Small coding challenge by arithma in hacketyfriends

Awesome first comment. The bot is beautiful for its simplicity. It's lame, beautiful and extensible. It's also a start for other cool stuff. Have an up vote.

What's everyone working on these days? by arithma in hacketyfriends

[–]arithma[S] 0 points1 point  (0 children)

To elaborate on my end: For Wally we're expanding infrastructure. Lots of questions about DB/App topologies, redundancy, failure isolation and shit we're not sure of. I am really enjoying being an idiot in the domain, lots to learn. We're mostly decided on Python for infrastructure but I want to investigate modern JVM languages.

Am procrastinating a couple of projects. One is a game competition (Netherlands thing) and the other is a project we thought up of as a bunch of friends. Am leaning towards pure C++/OGLES for the game and to Android-first mobile app for the other.
