I'm currently looking for diagramming software that allows me to quickly map stuff and jot down concepts such as a filesystem directories represented by nested boxes containing icons (representing files.)
Off course the simplest solution of all would be to just use paper and pencil, but unfortunately i have such poor motor skills that after minutes i cannot even distinguish the shapes I've drawn myself, never mind have these notes be of any use to someone else in order to have him/her work with them.
So far I've tried a ton of software packages but none of it seem to be simple/flexible/powerful enough to help fulfill the modeling /sketching tasks I'm trying to achieve
Visio,
smartdraw
Edraw
conceptdraw
Vue
yEd
Dia
Kivio
paint.net
photoshop
Illustrator
GIMP
in addition I've played around with modeling tools including staruml,argouml and Visual Paradigm as well as Eclipse modeling, but most of them were too complicated, too constricting and in some ways completely alien. On a side note, I absolutely HATE eclipse, I'm used to writing shellscripts with nano on a shell, The sheer amount of features (That i will never ever have any use for) make it hard for me to find that which I'm really looking for. YAGNI GDDMM*T!
Allthough UML modeling is at times important, such models are more for the next follow up phase and would be overkill (as well as a creativity killing burden) when I'm trying to come up with something from scratch.
Right now I'm looking for something new, I would be more than happy if someone could perhaps suggest something,
Most importantly i would like to find a program where the software allows me to do add new shapes and with the parent shape automatically growing so that that added shapes all fit inside of it rather than that i have to manually resize the parent shape
Your problem is a common one, and in recent years the big UML tool vendors have started adding functionality for sketching, as opposed to traditional modelling. My favourite, Enterprise Architect from Sparx Systems, has got "whiteboard" sketching and is also able to import from Visio.
It boils down to whether you know you'll just want to sketch, in which case you should get a tool which does that really really well (that last feature you mentioned is something I haven't seen in any UML tool). If on the other hand you know that you'll eventually want to turn the sketches into UML models, you need to consider whether you'll want to start over (which might be the easiest option, honestly) or have some sort of in-tool support to do that.
For "UML as a Sketch" I use the Hruby UML Stencil for Visio. These do not enforce eny semantics, so you can be as sketchy as you need to quickly record ideas and communicate.
See http://www.softwarestencils.com/uml/index.html
I use Dia. It is cross platform. Very simple tool.
However, My favorite has always been to sketch it on paper and scan (fotopragh it on my mobile) and keep it for records. Nothing beats pen and paper yet !
I tried yEd recently, because I happened to see it mentioned in another thread here. I'm quite impressed with it. Its pretty easy to use. I think the feature I liked the most is that I can draw my diagram regardless of the spacing and orientation. Then 1 button and poof, the whole things rearranges into the ordering I want.
As a linux diagramming tool, im pretty impressed with it.
this one is good for remote team members.
Nothing to install
http://www.dabbleboard.com/
I've used Visio for so long IMHO nothing beats it.
That said, I rarely use Visio in meetings to take initial notes. We'll diagram on whiteboards (get someone else to do the diagramming while you "facilitate") and then I take pictures of the result. Transcribing the photos to a Visio diagram helps me think it through.

I'm supposed to learn how to use LabVIEW for my new job, and I'm wondering if anybody can recommend some good books or reference/tutorial web sites.
I'm a senior developer with lots of Java/C#/C++ experience.
I realize that this question is perhaps more vague than is intended on stack overflow, so how about this? Please answer with one book or web site and a brief description. Then people can vote up their favourites.
It will take some training and some time to learn the style needed to develop maintainable code.
Coming from Java/C#/C++, you probably have a good idea of good software architecture. Now you just need to learn the peculiarities of LabView and the common pitfalls.
For the basics, National Instruments offers training courses. See if your new employer can send you to a Basics I/II class to get your feet wet. They offer some online classes as well. Following classes, you can sign up to take tests for certification.
Get an evaluation copy of Labview from National Instruments; they have a well maintained help file that you can dive right into, with example code included. Look at "Getting Started" and "LabVIEW Environment". You should be able to jump right in and become familiar with the dev environment pretty quickly.
LabVIEW, being graphical is nice, but don't throw out your best practices from an application design point of view. It is common to end up with code looking like rainbow sphaghetti, or code that stretches several screens wide. Use subvi's and keep each vi with a specific purpose and function.
The official NI support forums and knowledgebase are probably the best resources out there at the moment.
Unofficial sites like Tutorials in G have a subset of the information found on the official site and documentation, but still may be useful for cross reference if you get stuck.
Edit: Basics I/II are designed to be accessible to users without prior software development experience. Depending on how you feel after using the evaluation version, you may be able to move directly into Intermediate I/II. NI has the course outlines available on their website as well, so you know what you're going to cover in each.
LabVIEW for Everyone is recently revised and quite comprehensive. Other than the free stuff available on the Web, this is probably the best place to start learning the language.
The LabVIEW Style Guide is a great book on how to organize and arrange your code and files for maximum benefit.
Object oriented programming is a recent addition to LabVIEW. The LVOOP white paper explains much about how it works and why the way it is the way it is.
It's a bit out of date, but LabVIEW Advanced Programming Techniques by Bitter, Mohiuddin and Nawrocki is still full of useful stuff.
The National Instruments forums are a great place to go for basic help. The LabVIEW Advanced Virtual Architects (LAVA) is the community forum for advanced topics.
Tutorials in G, also check out the webring.
-Adam
The official NI support page and support forums are hard to beat.
It really helps having a guru around for LabVIEW.
'Arc the daft' pretty much nailed exactly what one should try to do to learn LabVIEW. However, I would not skip Basic's I and II. The classes do teach basic programming concepts and are geared to non-programmers, however they do cover the IDE extensively. The LabVIEW IDE is strange coming from a text based language and spending the time in the class learning it with an instructor can really accelerate your learning.
I would skip Intermediate 1 if you are a seasoned developer. Intermediate 1 tries to teach software engineering practices in the span of a three day course. If you are studying to get your CLD you need to know the course and the terminology for the exam, otherwise I wouldn't spend my time or capital in the course.
Subscribe to the Info-LabVIEW mailing list. It's got a lot quieter in recent times as the NI and LAVA forums have grown in popularity, but it's still read by some very experienced and helpful people, including people at NI, and if you can't find what you need elsewhere then a good question will usually get a good answer.
The NI style guide, as already mentioned, is a good reference - re-read it as you learn about more of the things it covers, it contains some densely packed good advice.
Personal top tips: look at the supplied example code (although it's not necessarily perfect); learn to use queues and notifiers as soon as possible; don't dive in to using event structures and control references until you've figured out what you can and can't do without them; and start small and simple - you should find it easy to reuse this code later on by repackaging it into subVI's as the scope of your ambitions increases. And have fun!
For me the best way to learn LabVIEW was by analyzing the in-build examples. The best forums are NI Developer Zone Community and LAVA Forums
LabVIEW is really easy to work with but the tricky bit is to know how to design your application so that it will not becaome a spaghetti. Once you get the basics (e.g. LabVIEW Introduction Course) learn how to use design patterns, events, queues, typedefs and references. Use modular architecture, avoid big structures, try 'writing' your code in small window.
It is also important to know the differences between LabVIEW versions (full/pro, and ver 7.1.1, 8.2, 8.5, 8.6, 2009), how to use version control system with the vi's (binary files), and how to keep your files in project so that you can easily reuse any code and be "DRY" (don't repeat yourself), how to build executable and what LabVIEW RunTime Engine it needs (for customers), what is DAQmx and how to use it, what are VISA drivers and which version is correct for you settings, how to use Measurements & Automation program..
When I started with LabVIEW a few years ago I was given a link to the LabVIEW Graphical Programming Course. It covers the basics and having a sound knowledge of other programming languages I think helped me pick things up quickly.
I would start with the LabVIEW wiki.
Specifically, LabVIEW Tutorial. There are lots of online references and links to LabVIEW reference books. Welcome to the world of LabVIEW!
I would suggest you start with LabVIEW for Everyone. Its a good book which covers the basics of LabVIEW well.

I'm trying to choose a tool for creating UML diagrams of all flavours. Usability is a major criteria for me, but I'd still take more power with a steeper learning curve and be happy. Free (as in beer) would be nice, but I'd be willing to pay if the tool's worth it. What should I be using?
Some context: Recently for graduate school I researched UML tools for usability and UML comprehension in general for an independent project. I also model/architect for a living.
The previous posts have too many answers and not enough questions. A common misunderstanding is that UML is about creating diagrams. Sure, diagrams are important, but really you are creating a model. Here are the questions that should be answered as each vendor product/solution does some things better than others. Note: The listed answers are my view as the best even if other products support a given feature or need.
Are you modeling or drawing? (Drawing - ArgoUML, free implementations, and Visio)
Will you be modeling in the future? (For basic modeling - Community editions of pay products)
Do you want to formalize your modeling through profiles or meta-models? OCL? (Sparx, RSM, Visual Paradigm)
Are you concerned about model portability, XMI support? (GenMyModel, Sparx, Visual Paradigm, Altova)
Do you have an existing set of documents that you need to work with? (Depends on the documents)
Would you want to generate code stubs or full functioning code?(GenMyModel, Visual Paradigm, Sparx, Altova)
Do you need more mature processes such as use case management, pattern creation, asset creation, RUP integration, etc? (RSA/RSM/IBM Rational Products)
Detailed Examples: IBM Rational Software Architect did not implement UML 2.0 all the way when it comes to realizes type relationships when creating a UML profile, but Visual Paradigm and Sparx got it right.
Ok, that was way too detailed, so a simpler example would be ArgoUML, which has no code generation features and focuses on drawing more than the modeling aspect of UML. Sparx and Visual Paradigm do UML really well and generate code well, however, hooking into project lifecycles and other process is where RSM/RSA is strong.
Watch out for closed or product specific code generation processes or frameworks as you could end up stuck with that product.
This is a straight brain dump so a couple details may not be perfect, however, this should provide a general map to the questions and solutions to looking into.
NEW - Found a good list of many UML tools with descriptions. Wiki UML Tool List
For sequence diagrams, only, try websequencediagrams.com. It's a freemium (free for the basic tasks, paid for advanced features) product, and lets you quickly bang out a diagram without any fussing around with lines and stencils.
Alice->Bob: Authentication Request
note left of Bob: Bob thinks about it
Bob->Alice: Authentication Response
For me it's Enterprise Architect from Sparx Systems. A very rounded UML tool for a very reasonable price.
Very strong feature list including: integrated project management, baselining, export/import (including export to html), documentation generation from the model, various templates (Zachman, TOGAF, etc.), IDE plugins, code generation (with IDE plugins available for Visual Studio, Eclipse & others), automation API - the list goes on.
Oh yeah, don't forget support for source control directly from inside the tool (SVN, CVS, TFS & SCC).
I would also stay away from Visio - you only get diagrams, not a model. Rename a class in one place in a UML modelling tool and you rename in all places. This is not the case in Visio!
For my simple & short UML working,
I've used this tool:
StarUML - http://staruml.sourceforge.net/en/
Great free software for UML drawing.
Although the original Star UML is no longer maintained, there's now a fork called White Star UML, which is actively developed.
As I usually use UML more as a communication tool rather than a modeling tool I sometimes have the need to flex the language a bit, which makes the strict modeling tools quite unwieldy. Also, they tend to have a large overhead for the occasional drawing. This also means I don't give tools that handle round-trip modeling well any bonus points. With this in mind...
When using Visio, I tend to use these stencils for my UMLing needs (the built in kind of suck). It could be that I have grown used to it as it is the primary diagramming tool at my current assignment.
OmniGraffle also has some UML stencils built in and more are available at Graffletopia, but I wouldn't recommend that as a diagramming tool as it has too many quirks (quirks that are good for many things, but not UML). Free trial though, so by all means... :)
I've been trying out MagicDraw a bit, but while functional, I found the user interface distracting.
Otherwise i find the Topcased an interesting project (or group of projects). Last I used it it still had some bugs, but it worked, and seems to have evolved nicely since. Works great on any Eclipse-enabled platform. Free as in speech and beer :)
As for the diagramming tool Dia, it's quite ugly (interface and resulting drawings), but it does get the job done. An interesting modeling tool free alternative is Umbrello, but I haven't really used it much.
I definitely agree with mashi that whiteboards are great (together with a digital camera or cellphone).
Probably some of the nicest tools I've used belong to the Rational family of tools.
You may be looking for an automated tool that will automatically generate a lot of stuff for you. But here's a free, generally powerful diagramming tool useful not only for UML but for all kinds of diagramming tasks. It accepts as input and outputs to a wide variety of commonly used file formats. It's called yEd, and it's worth a look
Visual Paradigm for UML http://content.usa.visual-paradigm.com/websiteimages/images/products/vpuml60/vpumltitle.gif
I'm very fond of Visual Paradigm for UML It's very powerful and has a free Community Edition and cheap Personal Edition as well.
Agilian http://content.usa.visual-paradigm.com/websiteimages/images/products/ag10/agtitle.gif
For Agile modeling there's also Agilian which is a bit more flexible, adds extra features to support smartboards and knows mind-mapping as well.
The thing I like most about their products is the flexibility. I'm using Enterprise Architect at work nowadays but I think it's not smart enough. I want to be able to quick-brainstorm some sequence diagrams and have the application keep my model up-to-date in the background, something VPUML does a very good job at.
In my opinion it's way better than Enterprise Architect, though that is a great tool as well :)
Take a look at BOUML: multiplatform (QT), works pretty well and supports colaborative work.
BOUML is a free UML 2 tool box (under development) allowing you to specify and generate code in C++, Java, Idl, Php and Python.
BOUML runs under Unix/Linux/Solaris, MacOS X(Power PC and Intel) and Windows.
From Wikipedia:
The releases prior to version 4.23 are free software licensed under GPL. BOUML 5 and later is proprietary software.
If you're looking to get out the door and working on UML without having to learn a complex new tool I would check out Violet UML. I've used it to some pretty great success in the past.
PlantUML is an open-source markup-language-to-UML-diagram tool in Java that deserves to be mentioned here. It ranks high on the usability scale because of its intuitive syntax for the various diagrams and diagram components.
Dia is a possible choice. It's definitely not the best tool, but it is functional.
Enterprise Architect from Sparx systems is the best tool I've used. A bit expensive at $199 (professional edition), but IMO it's worth it.
I will add UMLet which I haven't tried yet, but have been selected at my office to start doing diagrams.
Looks simple, diagrams aren't sexy, but it seems quite complete with regard to the kind of diagrams you can do. Seems to have good export capabilities too (important!), is flexible can support custom components) and can be used as Eclipse plugin.
Astah UML (ex-JUDE) is pretty good.
I haven't been able to find a top-notch free UML diagramming tool, but if you're interested in pure diagramming, as opposed to round-trip-engineering, I'd go with Microsoft Visio. If you want full round-trip engineering, Rational Rose.
This list of UML tools on Wikipedia might also come in handy.
Pen and paper. If you can get the scan into a vector format, that may be useful when making minor amendments.
You should try Creately. Runs in your browser and can do team collaboration.
supports sequence diagrams, class, ER, usecase etc. works great and has a free version available.
Creately.com
You can also check out Lucid Chart for uml and other types of diagramming.
Don't forget yuml.me, I love it.
http://plantuml.sourceforge.net/index.html
In my practice i use Sequence Diagram Editor. it is really fast and helpful tool. the one thing i don't like about it is that it is commercial product, not free.
I like VisualParadigm mentioned before in this thread. It's powerful and easy to use I think it gives most power comparing to other tools.
If you need something simple, quick and easy (and free) there is a great tool called UMLet - I highly recommend this. I've tried many of UML diagramming tools and this the simplest one (and it still allows to do great diagrams). This is my choice:)
Obviously if you are serious about UML in the long run you need to use a software UML tool like the ones suggested in the other answers, but I've found that a whiteboard is one of the best tools for UML diagramming, especially during the design phase, or when you are exploring different alternatives. Nothing beats a whiteboard for speed/flexibility in my mind. They are also great for collaboration assuming you are collocated physically.
In my opinion StarUML is the best.
I can't believe no one has mentioned NetBeans UML Editor, it's great and satisfied all of my Java based UML requirments.
This after I tested JDeveloper UML, ArgoUML and StarUML.
I recently conducted a poll "What UML Tools do you use?" in my blog. NetBeans UML was was the top opensource choice and Enterprise Architect was the top commercial choice.
You can create UML class, sequence, component, use case, and activity diagrams in Visual Studio 2010 Ultimate. You can link these diagrams to Team Foundation work items so you can plan and track development and test work. You can also create sequence, dependency graphs, and layer diagrams from code and use Architecture Explorer to browse and explore your solution.
I've posted more links on my profile for more info.
You might want to take a look at MagicDraw or Visual Paradigm for UML. Both offer community editions that, of course, don't span the full feature range, but may well be sufficient if you want to create diagrams only and not generate code or do full round-trip engineering.
Rational and Together/J are best-of-breed products, but expensive.
In my experience, I've enjoyed Eclipse Omondo and Sparx Enterprise Architect. Omondo integrates nicely with Eclipse for code generation, and has a very intuitive feel. However, it is strongly tied to Java. Sparx is a good tool for the price point, but lacks the full range of UML 2.0 diagrams.
Do NOT bother with Poseidon. It is buggy, bloated, and unusuable for all intents and purposes.
For sequence diagrams you can also try Trace Modeler. It's not free but it has a great interface, very friendly and productive. You can use it on any platform.
