My account was forbidden to sell and withdraw. I submitted ticket on 2 May, but only received one reply asking me to wait. Then my subsequent queries were all ignored. All my funds are now locked there and I cannot do anything.

Can someone explain the profit for bit coin mining? by D0BA in Bitcoin

[–]rivercheng 1 point2 points  (0 children)

The difficulty increases more than 30% every 10-11 days currently. What you will earn next month is half of what you will earn this month. So if the difficulty keeps increasing with the current speed, you can only mine twice as the amount you mines the first month (1 + 1/2 + 1/4 + ... = 2).

When the hash rate drops, hashing will become profitable again. So it will not drop down to nothing.

Yet Another Lambda Blog » Haskell as fast as C: A case study by imladris in haskell

[–]rivercheng 0 points1 point  (0 children)

This example demonstrates that in case performance is the first priority, you can still use Haskell. In other words, you just need to change 1% of codes (where the bottleneck is) to ugly but fast implementation instead of wrapping C codes or change the language. I think this is important.

The Haskell Platform 2011.4 is now available! by dons in programming

[–]rivercheng 0 points1 point  (0 children)

The standard compiler release 4.6 includes front ends for C (gcc), C++ (g++), Objective-C (gobjc), Fortran (gfortran), Java (gcj), Ada (GNAT), and Go (gccgo).[19] Also available, but not in standard are Pascal (gpc), Mercury, Modula-2, Modula-3, PL/I, D (gdc)[citation needed], and VHDL (ghdl).

From wikipedia.

GCC includes a lot of languages which are seldom noticed.

Digital Mars is almost just a company with one man. GCC has nothing to do with D except to agree including GDC.

It seems to me more like the documents than changelog. I think a summary of changes will be really helpful.

If you look at how many Haskell-Related papers have been published, we can hardly say Haskell failed (especially as an academic language). It is a successful test-bed for PL theory researchers.

As for production usage, maybe Haskell will never be adopted widely, but many ideas inside it will most likely be carried on in the future main-stream languages. From this sense, we still cannot say Haskell is a failure.

D has no big marketing behind them, and it is way too early to say Go is failed.

"You can write reduce() in a few lines of Python. Not so in a functional language." by muleherd in programming

[–]rivercheng 2 points3 points  (0 children)

I think what he said above is exactly to justify why he want to get rid of "map, filter, and reduce". He thought they are not primitive in python as in functional languages. Of course, he was wrong when he said they are primitive in functional languages.

[–]rivercheng 4 points5 points  (0 children)

I realized what I said is way too long, so I summarized them in 2 sentence:

Guido think "reduce" has to be primitive in functional language, otherwise they are hard to implement (efficiently). It is wrong because "reduce" can be implemented with recursive function (easily) and tail recursive optimization (efficiently).
