Programming :: Unified Modeling Language Good/Bad And Tools?
Jan 29, 2010
I just joined a research group that is about to embark on writing a big multi-physics code package. Before the programming gets so big it is unmanageable, I was thinking about best practices and similar things. In that process, I came across something called the "Unified Modeling Language" (UML). Also, looking at a, cross platform, free, tool, that is good for C++. Ideally with reverse engineering and code generation. I came across Bouml, found ArgoUML. The former seems to support forward and reverse C++, the latter doesn't. Also, it seems that Visual Paradigm has a "Community Edition" that is free for non-commercial use. Then there are more on the Wikipedia page. I would like to hear from users what they like and don't like. Looking for reviews here.

We have to (re)write a bunch of scripts to download files from remote ftp servers, where we won't know the names beforehand; move the files to an archive folder on the FTP server; copy the files to the correct servers on our LAN; and log the file information in Oracle.Our current scripts are for a windows product called ScriptFTP that provides a nice little language. It does everything except the logging, but we're wanting to get rid of Windows.
I have recently been given the job of maintaining the code, and I'm looking for a good language for simple, robust ftp scripts that will work on Linux. We have some customers with remarkably unreliable FTP servers. If necessary, I can write another program to handle the logging to Oracle. I'm usually a C++ developer, so a similar syntax is a bonus. I also want to be able to hand this over to an entry-level programmer later.
So far, I'm intrigued by PHP, but I've hardly had a chance to look at it for any scripting. I like the idea of being able to loop through the files individually and even be able to skip over anything that looks like it's currently being written (either based on the file name or date/time). I've thought about writing something in C++ that would take a simple config file instead of a full blown script. However, I don't want the maintenance, unless someone writes a quality FTP library that is inexpensive (hopefully free) for commercial use.

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 am unable to find a description of alsa's programing language, this sort of stuff:

I need to know what, for example, 'ttable' means and what is its syntax. This seems to be a state secret.

I wonder why arrays in the C programming language are pointers to the first element of the array, not the first element of the array itself?

I am an engineer. What distribution has the best support for mathematical and 3D modeling software? I also do some photo editing so it would be great if the distro also had support for that.

2) the most left corner 'hidden button', once you press all the tabs gone (application & terminal) . How to restore this condition?

My name is Simon and I have recently moved Ubuntu 10.04 from Windows XP. I am a programmer with a few years under my belt using a range of languages but primarily Microsoft Visual Foxpro. This program was very useful as it allowed me to access tables stored on my system and create programs to manipulate data in a wide variety of ways. Programs could be hobbled together, refined then placed in a menu system.I have been looking at a range of packages to use that would (a) allow me the same interactive experience, (b) allow me access to xbase tables (especially as most of the packages and business clients I have use this format), and can be used to create a GUI program. Ideally the package could create programs that can run relatively easily on Linux and Windows. Why, you might ask? Well unfortunately I have not been able to ditch foxpro, it is kind of unique in its abilities. Consequently I am using XP in VirtualBox to do some of my analysis and report production. I also still run Windows on my slate computer, which is used in the field to collect data.I have investigated Python/Jython, Java, Bash, and a number of others (e.g things that interact with PostSQL, MySQL, etc) but happily admit that I am overwhelmed with alternatives. That said, none quite match my relatively simple requirements stated above. The biggest problem is the lack of interactive data manipulation -- e.g. type an SQL statement and have the result appear immediately, that sort of stuff.
I need a language with strong data access, manipulation and reporting capabilities. I have sizable tables/databases containing millions of records and at present most queries take only a seconds using Visual Foxpro. Most of my investigations push me to the MySQL and similar data repositories, but all have their own format. Essentially I need to import all my data into their system before a language can access the data (note that there are copyright issues preventing this in some situations) - aren't there any programs that can access dbase or foxpro tables directly?The programming language also needs to be relatively mature. I don't want to spend all my time defining window sizes and button locations. Editors/Wizards that help design a GUI interface is preferable. It is imperative the language also has strong string, number, array and table access capabilities. Code should also be intuitive and easy to read. A lot of the languages I have reviewed are not intuitive. To me, functions in the format substr(string, start, lengthsegment) is logical and easy to follow. Things like Str = ${str//search/replace/} are not.
I suppose while I am listing preferences, an interpreter like eclipse would be desirable to help maintain code and format it as you go. Some sort of intelligent feedback as you construct a code snippet showing you what alternatives are available would also be valuable.At present I am leaning towards Python with Eclipse as the program manager, but as stated this setup does not really provide an interactive experience and does not appear to naturally interact with dbase. It appears this option would require considerable setup to get working.Java + Eclipse has been suggested before, especially as it takes away the need to worry about operating systems, but most of the packages I have used based on this language are restricted by library development by Sun Microsystems. The file chooser is a classic example - a known bug has been registered for this library for 5+ years and the problem has not been fixed.

I'm currently working on telling my Ubuntu Laptop to do everything I'm able to do with my MacBook. Not so much the look (I love Ubuntu's look) but the functionality.I somehow can't seem to get a unified inbox in Evolution. I got 6 IMAP accounts each with a separate inbox which is quite annoying. I've gotten used to Apple's Mail.app and I'm missing that option in Ubuntu.The only thing that COULD be a unified inbox would be "On this Computer" but I don't see any option to integrate my accounts to it.

I want to set up a system with two windows oses.
a) Windows 7
b) Windows XP
Windows 7 will be installed to one partition, and xp will be restored to a second partion from a ghosted image. I don't want the headache of having to guess who or what is fighting to control the boot sector. When the fight is over I simply want to walk up stick in a cd run a utility and install a booter/loader over what ever is there. I want to be able to do it adhocly so it must be able to on install always scan for any already installed OSes and set them up in a nice selection menu at boot.
GRUB 2.0 came to mind. What I want to know is if that sort of thing is possible. Can I install/restore multiple OSes to a disk, and then when all is done pop in a live CD and install/repair GRUB 2 to the system? Even if UBUNTU or any linux is not on the system and have it perform the above scenario as described?

Running this software:
Linux 2.6 on a hacked LaCie NetworkSpace
installed SSHd 5.4
installed Samba 3.4
installed lighttpd 1.4
installed ProFTPD 1.3
I want:
Login with my account and same password on all of those. When i use passwd, the change should be reflected on all of them.
I have:
Samba uses encrypted passwords, and i must change passwords for samba with smbpasswd.
lighttpd uses separate password file, must change by hand.
ProFTPD and SSH use system login (/etc/shadow).
So far i found two possible solutions, but can't tell if i understood them right or how to achieve them: use LDAP as auth backend If i could make LDAP my auth backend, provided this is possible at all, lighttpd would use this directly, and PAM would use it for system login. Nevertheless, actually this can't work as Samba uses encrypted passwords. Correct? use Samba password backend, then make LDAP use that If passwd, login, etc would use Samba, i would work everywhere with MD4 hashed stuff. Lighttpd would send plain passwords (HTTP basic auth), and query LDAP, which in turn makes an MD4 hash, and tests for Sambas passwd. Will this work?

I want to know which is the best scripting language right now and what you guys think its going to be the best or most used in the future, that is, in about 5-10 years. Take into account system administration and applications. This are the languages i had in mind, add more if you think other scripting languages are better or worth considering.

Now I have a project which include three directories /bin, /inc and /src. All of header files (*.h) are included in /inc and all of source(*.c) files are stored in /src, i.e. a.c, b.c, c.c..., the final generated executable file will locate in /bin. after compling with makefile, all of obj files will be generated in /src/obj like a.o, b.o, c.o, d....! Moreover an final.exe executable file will be generated in the /bin directory. Now if I want to debug it with GDB, how can I do it?

so with every language I have used, I have found that my style of programming is sub par (terrible at times). I have worked with a good amount of languages lately including bash, C, Java, JavaScript/jQuery, Perl, PHP, Shakespeare, Zombie, etc. I have done a good amount of programming, and in the end they seem to work, but just looking like a piece hacked together. Does anyone know of any books or online guides that help with programming styles and advancement of such?
