Line 1:
==Latest entry?==
Does latest entry mean the most recent entry made or the most recent entry date? For Erlang I have implemented ''made'', but I can change.
If it is the latter (date), what about many entries the same date? All of them or the latest made?
==Name change?==

:: thanks. i attribute it to my inability to read the J code to figure that out myself--[[User:EMBee|eMBee]] 17:04, 9 February 2012 (UTC)
== The Lisp code is bugged ==
Attention is needed to the common lisp code of this task as it is not properly implemented.
: could you please explain what's wrong with it?--[[User:EMBee|eMBee]] 23:19, 11 March 2012 (UTC)
== The end of a phrase is nigh ==
I noticed that the task description says ''"... and saved to disk"''. Will that become "and saved to ssd" or "and saved to secondary storage" soon?
Personally I would like the phrase to linger long after home computers stop using rotating disk. --[[User:Paddy3118|Paddy3118]] 20:50, 6 July 2012 (UTC)

:Should be fixed. The [http://rosettacode.org/mw/index.php?title=Simple_database&diff=155789&oldid=153280 last editor] forgot to change the parameter types for the function at the bottom.
:Valgrind reports an invalid read (also if I run the [http://rosettacode.org/mw/index.php?title=Simple_database&oldid=133351#C original code]) but I'm not in the mood tonight to investigate further :-). --[[User:AndiPersti|Andreas Perstinger]] ([[User talk:AndiPersti|talk]]) 21:07, 26 March 2014 (UTC)
:: I've made some changes. Now code compiles and runs without segmentation fault. Please check consistency of code style. Unfortunately that "simple DB" not usable for me, because keeps all data in memory and consumes five times more memory compared to the size of the file. --[[User:Yamiyam|Yamiyam]] ([[User talk:Yamiyam|talk]]) 15:47, 29 March 2014 (UTC)
