Anyone here interested in k / kdb and being able to link with dmc?? yes, you have to register to get the download but believe me it is a really cool programming environment and it is bloody fast! (only about 200KB) 3 files in c:\winnt http://www.kx.com/download/download.htm check out their customer list! http://www.kx.com/customers.htm the programming language (k) is similar to python, but it much much faster. the database (kdb) was written in (k) and is 10 to 100 times faster than oracle, db2, sqlserver. you can extend kdb to have your own operators! (which can be written in k, c, or c++) based on a series of commands, kdb will load up your dll(and/or lib I can't remember) and you can call the appropriate functions! I was hoping Walter and Digital Mars People would be interested in it because it is so small!

Can you offer a 1 paragraph motivating description of k?the database (kdb) was written in (k) and is 10 to 100 times faster thanoracle,db2, sqlserver. you can extend kdb to have your own operators!

ok i'll try to impress in one P! K is a derivative of APL which is an interpreted language. If you are familiar with python, k has similar data structures: lists, dictionaries, and everything is loosely typed. Coming from the C++ world one would think this is a bad thing, but there are only 4 major types. int, float, string, symbol (q the next generation of the language has a few more types). k has a built in webserver, gui, charting engine, spreadsheet engine, etc etc. too much to list! and best of all k is basically 2 files. k.exe and k20.dll (on win32) which total 182KB - there is nothing else (unless you install the database which is 50KB and can handle about 1000000 inserts per second). There are obviously downsides to k ... there are few libraries, the language can be a bit hard to learn for noobs, and not that many people use it, however, those that use it as am embedded analytical engine find none better. k can also load up c functions and vice-versa! you can extend the language any which way you want. I hope this link is a bit better: http://www.kx.com/document/kref.pdf it is quite long but you will really get a good sense of what the language is trying to accomplish. It is clearly NOT meant as a replacement for C or C++, but after using it for a while, you may change your mind. There is also a very good folder with random k scripts that showcase the power of k. http://kx.com/a/k/examples/ And here is a small program in k (just these five lines let me know if you have trouble) (took me about 30 seconds to write this program) /put in a file called my.k v:!20 +/v +/v%#v \t +/!5000000 \t +/!9000000 v:!20 creates a vector of ints from 0 to 19 and assigns it to v +/v is the sum of the vector +/v%#v the sum (+/) of the vector elements divided (%) by the \t +/!5000000 times how long it takes k to sum the vector of ints from 0 to 4999999 .. about 187 ms on my Dual PIII (each CPU is 933Mhz) \t +/!9000000 times how long it takes k to sum the vector of ints from 0 to 8999999 .. about 328 ms THIS is how you invoke the k interpreter on your file! kinda like python (remember no compiling is a plus!) D:\>k my.k K 3.2t 2004-03-23 Copyright (C) 1993-2004 Kx Systems WIN32 2CPU 1023MB xxxxxxxxx.yyyy.ssssss.com 0 EVAL 190 9.5 187 328 now just for fun, try writing this program in C++ or Java or C or any language of your choice and tell me how long it takes :) remember it took me about 30 seconds for this one!

Friday night and all my friends are busy my life sucks! ok but on another note, the reason I like both k and dmc is they are both very fast, compact, and powerful. I know Walter is releasing D on linux, but I wish he would release dmc on Linux! It would be amazing! maybe it could even compile the linux kernel! But I don't know how hard it would be for him to port it because the object, shared object, and executable are all in different formats.... I'm sure he has been asked this before but could dmc be ported to linux?

It appears that porting dmc to linux just isn't a priority at this time for Walter (can't imagine why <g>; D workload have anything to do with it? ). Porting to Linux has been the way to go for several compilers these days; OpenWatcom is already working to this end. Nonetheless, it would be great to see dmc on Linux, if it could ever happen. The compiler's got to be the fastest one out there. Later, John

What about Mac OS? Symantec C++ was available on Mac OS in the past. If Walter ported Digital Mars C++ to several platform, yeah! lots of people will kick gcc away :) In article <cbkuhm$15mq$1 digitaldaemon.com>, John Reimer says...Anuj Goyal wrote:Friday night and all my friends are busy my life sucks! ok but on another note, the reason I like both k and dmc is they are both very fast, compact, and powerful.

Anuj Goyal <Anuj_member pathlink.com> i wholeheartedly agree :) (IMHO only 3 architectures will make it to 2010) x86-64, POWER, IA64(HP has too much invested to let it die) though in 2015 it may be a completely different ballgame!
