Today I saw the topic. sum-even-numbers-1-100 At that time, it was already closed but not the point. Other thoughts came to mind.
All newcomers to Haskell are afraid that when they study it, their brains will turn inside out. I did not notice anything like that. And all because the brains of all Unicsoids are initially in the correct position. Let's look at an example concerning this theme.
On Haskell you need to write one line.

I have a simple script that I want to run every 30 minutes but only when I execute it. I don't want it to be a crontab job.

Hi,
I have a script where I am trying to set a local variable using the following,
MYVAR="$NAME"_"$NAME2".txt
where say,
NAME = one
NAME2 = two
so I want the output one_two.txt but what I am getting is,
two.txt
basically the $NAME2 is overwriting, what am I doing wrong?

egrep -A 7 -m 2 -h 'Date:|Time:' *.html
this is showing only 2 line after the context of the 2nd found match. Is this a bug in grep?

Consider the following code:

threadscope
THREADSCOPE(1) General Commands Manual THREADSCOPE(1)NAME
threadscope - a graphical thread profiler for Haskell GHC programs
SYNOPSIS
threadscope [program.eventlog]
DESCRIPTION
Threadscope is a graphical thread profiler for Haskell programs.
It parses and displays the content of .eventlog files emitted by the GHC 6.12.1 and later runtimes, showing a timeline of spark creation,
spark-to-thread promotions and garbage collections.
This helps debugging the parallel performance of Haskell programs, making easier to check that work is well balanced across the available
processors and spot performance issues relating to garbage collection or poor load balancing.
ARGUMENTS
threadscope takes the name of the GHC RTS event-log file to process as its single argument. If no filename is given, threadscope starts
with an empty workspace, where any event-log file can be loaded by means of the GUI file browser facilities.
USAGE
In order for threadscope to be useful, you have to compile your Haskell program to use GHC's threaded run-time and also to create runtime
profile logs. This can be accomplished with the following command line options to ghc(1)
$ ghc -threaded -eventlog --make Foo.hs -o foo
Once the program is built, execute it using the multithreaded run-time, specifying the number of HECs (Haskell Execution Contexts) to use
in the usual manner, but also requesting the creation of an event log. For example, to use two HECs and create an event log you would use
$ foo +RTS -N2 -ls -RTS ...
Once the program runs to completion, a file named foo.eventlog is produced. You can start threadscope from the shell prompt passing the
event-log filename as the single argument, or you can start threadscope from the desktop menus and use its file browsing capabilities to
find and open it.
