Programming :: Is Java Free For Use For Business Purpose
Dec 28, 2010
I learned Java(SE,EE) few years ago and didn't use it because we are using PHP and ASP.NET at work.However, I would like to ask a question: Is Java (SE,EE) free for use for business purpose?I mean,if I start up a company and use tomcat with java, do I have to pay for the license to use Java?I don't know much about java license until I learned that ASF(Apache Software Foundation) quited from the Java Community recently.As a result,they recalled my attention regarding the legitimacy of using java in business purpose for free.

I am certainly a Linux Newbie..I have a business with a network of PCs that need not get client files corrupted by viruses & other bad things from the internet...YET I would like to let my employees(who are way worse newbies than me..om Windows even...& stand good chance to mess up computers) use internet at times if they wish. My first thought was just separate side by side PCs, one to get on for Clients/business network etc, & the other to get trashed by the internet.
What I am thinking is a better alternative (& I need to know from yall who I'm sure are way beyond this newbie whether this thinking is correct) is to put something like Puppy Linux 5.0 on small memory USB flash drives & let them each have one to use for internet, simple application functions etc. Can I safely believe that running internet browsing on the flash drive with Puppy Linux booted & running as the OS is NOT going to potentially infect my windows XP business PCs with viruses etc?

what is the purpose of the parameter within single quotation marks and what it does? I am assuming it is a call to pkg-config with those paramaters.
Code: Select allgcc -o gtkprog gtkprog.c `pkg-config --libs --cflags gtk+-2.0`
Using:
Code: Select allpkg-config --libs --cflags gtk+-2.0
-pthread -I/usr/include/gtk-2.0 -I/usr/lib/x86_64-linux-gnu/gtk-2.0/include -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/libpng12 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng12 -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/freetype2 -lgtk-x11-2.0 -lgdk-x11-2.0 -lpangocairo-1.0 -latk-1.0 -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lpangoft2-1.0 -lpango-1.0 -lgobject-2.0 -lglib-2.0 -lfontconfig -lfreetype
So, if my logic serves me right, this command parameter is a neat replacement for this litany of libraries to be used in the compilation process.

Here is the code, which just creates a dynamic array? fills it? and prints.
At the end-point? when doing 'free(digits);' I get a debug messge. But the programm continues to work, or it crashes only on free?
How do I need to change the source-code, not to recieve a message from debugger?

Groovy is an object-oriented programming language for the Java platform. I do not have experience in Java, only perl and shell scripts. Recently I have been asked to maintain a software written in groovy (also to make enhancements). So can I learn groovy without knowing java language. or isit I have to learn java before venturing into groovy.

I need MatLab for a course at the university, but it's not an open source software as all of you know, so I wanted to know if there are valid freeware alternatives. I was told to use Octave or Scilab if I didn't want to buy the license and so I would like to know what's better in terms of MatLab compatibility and ease of use, if there are any other (and maybe better) alternatives and also if there are free Simulink-like programs.

Is there a way to hook calls to new/malloc, delete/free in C++? I tried the following methods: LD_PRELOAD -> fails for malloc, because dlsym seems to depend on malloc -Wl,--wrap,malloc -> doesn't work for 'new' gcc hooks -> doesn't work always, e.g. for uclibc there are no hooks Are there any other methods I could try?

We have a program that catalogs to 40 different mount points. The program is fine as long as thier is free space on at least one of the 40 mount points. My boss wants me to come up with a script that will email us daily to know how much overall free space is left. I know I can do a df but I don't know how to combine the 40 mount points into a single disk used/disk free report.
The 40 mount points are /dev/mapper/areaxx, xx being 01 to 40.

I need to monitor the amount of free physical memory on Linux from within a large C program. The sampling will occur very frequently, so the measurement cannot be performance intensive. The fact that Linux uses much of the theoretically free memory for cache and buffers means that just measuring the free pages is not sufficient. Using free + cache + buffers gives an overestimate as not all cache/buffers can be freed, but I could get a rough idea of how much generally can't and subtract that from the answer.
Possible options that I've come across so far are: Parsing /proc/meminfo - but that involves reading from file which is slow. Extracting the free, cache and buffers values from the output of the Free command - but is there a quick way to do this? Parsing the /proc/freemem file produced by the API here - but this is again reading from file. Is there a way to get that output directly? Speed is an extremely high priority, and the answer it must accurately represent the amount of memory that my program could expand into (to within a few Mb).

I'm creating a bash script to check how much free space is left in /var directory then, if it hits a certain threshold, delete certain files with numbers for extensions (e.g. fileA.1, fileA.2 fileA.3, and fileA.4, fileB.1, fileB.2 fileB.3, and fileB.4 ). Here's a snippet from my script:
[Code]...
If I use a * as a wildcard for the number extension, the script fails. Maybe regex would work here, but I'm not particularly accomplished at it. Or some other construct.

I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.

Situation: this semester I took an class called Introduction to Software Design with Java.It was my first intro to programming. The class had a very odd structure:1. The text was extremely high level. The first few chapters were all about object oriented programming, how objects interact, all about specification, etc (without ever talking about implementation).2. The lecture simply followed (directly) the text. And as a result was rather uninteresting.3. While highly theoretical (in that it was very high level approach), we never talked about how the computer was dealing with the information, etc.as all very "hand waving/magic" approach.
Okay so enough of the complaints:Question: This summer I'd like to dive a bit more into a language mainly out of frustration and lack of a good book. I'm thinking perhaps a lower level language.1. Would C++ be a good second language? Or should I give Java more time?2. If I am going to go with something else, is C++ sufficiently different, or should I go with C

I've had to do some code in java, a language I'm very much unfamiliarly with so please excuse my incorrect use of terms. The basic outline of my problem is I create a class object as a local within a swing button function it works fine. If I create it as a global ( with I think I need to do ) within main, then prototype it with the other swing objects at the bottom of the file when it is called it causes a host of problems. I think the easiest way is to show it.

I've just started programming at my university and I'm finding it a bit hard to get started. I've been given this for homework.Given 2 integers, a and b, print their sum. However, sums in the range 10..19 inclusive, are forbidden, so in that case just print 20The problem I'm having is that i don't know how to tell java to print 20 when the value is in that range.
