  • deriving activity diagram-based GUIs and CRUD them with a DB?

    - by Xin Tanaka
    i received a big book full of processes. i was thinking about the end user (they will be lawyers) and decided the best GUI would be showing activity diagrams or business processes. It reminded me Quickbooks and how non-accountants can successfully use it and understand accounting processes. i began doing research before sending my project to a bunch of programmers: is there some open source solution? can i use MS Visio libraries? which UML tool is programable? what about Eclipse and its modeling tools? etc etc the key points here are: relationships between events, artifacts, actors, etc should be stored in a database. processes or steps in a process should be easily modified by updating the database do this sounds too crazy? (should I explain a bit more why it must be programmed this way?)

  • When to use memberEnd and when navigableOwnedEnd in an UML class diagram?

    - by Ivan
    I've download a trial of Altova UModel and am starting using UML. As a practical beginning I am modelling a personal information manager application, which includes a web bookmark managing. A Bookmark can belong to many (or no) Tags at once and a Tag can contain many (or no if all the bookmarks it contained were deleted) bookmarks. The relation has to be both-way navigable - a user has to be able to see all Bookmarks with a particular Tags ans all Tags of a Bookmark. What is the correct UML relation between Bookmark and Tag classes? As far as I understand UML now, it is an Association (not an Aggregation). But for a 2-way navigable many-to-many relation I can specify ends roles as "memberEnd" or "when navigableOwnedEnd", graphically the connection looks the same in both cases (an arrow) (which as I understand means navigability) but a property appears in the class box in case only when "memberEnd" is used. How should I specif it in the model If I mean both-way navigable many-to-many relation there?

  • How do I get the sequence of numbers in a sorted-set that are between two integers in clojure?

    - by Greg Rogers
    Say I have a sorted-set of integers, xs, and I want to retrieve all the integers in xs that are [x, y), ie. between x and y. I can do: (select #(and (>= % x) (< % y)) xs) But this is inefficient - O(n) when it could be O(k log n) where k is the number of integers returned. I am just learning clojure so here is how I would do it in C++: set<int>::iterator first = xs.lower_bound(x); set<int>::iterator last = xs.upper_bound(y); for (; first != last; ++first) // do something with *first Can I do this in clojure?

  • How do I redirect stdin/stdout when I have a sequence of commands in Bash?

    - by Tom
    I've currently got a Bash command being executed (via Python's subprocess::Popen) which is reading from stdin, doing something and outputing to stdout. Something along the lines of: pid = subprocess.Popen( ["-c", "cmd1 | cmd2"], stdin = subprocess.PIPE, stdout = subprocess.PIPE, shell =True ) output_data = pid.communicate( "input data\n" ) Now, what I want to do is to change that to execute another command in that same subshell that will alter the state before the next commands execute, so my shell command line will now (conceptually) be: cmd0; cmd1 | cmd2 Is there any way to have the input sent to cmd1 instead of cmd0 in this scenario? I'm assuming the output will include cmd0's output (which will be empty) followed by cmd2's output. cmd0 shouldn't actually read anything from stdin, does that make a difference in this situation? I know this is probably just a dumb way of doing this, I'm trying to patch in cmd0 without altering the other code too significantly. That said, I'm open to suggestions if there's a much cleaner way to approach this.

  • Can CSS change the apparent sequence of elements, e.g. using float or position?

    - by ChrisW
    Edit: answer to this question is easy, a simple example of float left and float right. I'd like to float some annotations to the left of a topic using HTML and CSS, for example the 'status' and 'author' annotations shown in the following mockup/image: For semantic reasons, perhaps: I prefer to use CSS instead of a table-based layout In the HTML, the status should appear after the corresponding heading For example: <h1>This is a section title</h1> <div class="status">approved</div> <div class="author">chris</div> <p>This is some text. Lorem ipsum.</p> <p>Lorem ipsum.</p> <h1>Different section title</h1> <div class="status">rejected</div> <p>Lorem ipsum.</p> I'd like the annotations to be after the heading in the HTML, because everything associated with (i.e. the contents of) a topic is usually whatever is after the topic's heading. However I'd like the annotations to be displayed before (to the left of) the heading, as illustrated above. Is this possible? What is the most semantic HTML, and corresponding CSS, that will render as shown above? Would you recommend a table-based layout instead? Even if that means putting the headings in a table cell? It may not be possible; this answer suggests it isn't possible ... but I don't know CSS well enough to say that for sure.

  • How to check if numbers are in correct sequence?

    - by Nazariy
    I have a two dimensional array that contain range of numbers that have to be validated using following rules, range should start from 0 and follow in arithmetic progression. For example: $array = array(); $array[] = array(0);//VALID $array[] = array(0,1,2,3,4,5);//VALID $array[] = array("0","1");//VALID $array[] = array(0,1,3,4,5,6);//WRONG $array[] = array(1,2,3,4,5);//WRONG $array[] = array(0,0,1,2,3,4);//WRONG what is most efficient way to do that in php? UPDATE I forgot to add that numbers can be represented as string

  • SRAM Cell Diagram - Can someone explain this a bit more clearly? ( From COMP1917 @ UNSW: Lecture 2 o

    - by Kristina
    I've begun watching a series of first year lectures from the University of New South Wales (UNSW) in Australia, and I'm a bit perplexed by the instructors explanation of how an SRAM gate works. I realize this isn't exactly "programming-related" but since it comes from a series of lectures relating to computing and programming, I thought StackOverflow may be able to help (reddit failed me entirely). In this lecture beginning at around 32:12, Richard (the lecturer) tries to explain how a "latch gate" works within SRAM. Although his students seem to keep up, I feel I'm missing something crucial which is preventing the concept from really "clicking" in my brain. For convenience, I've added the image from the video below: Thanks in advance for any help you can provide, but if this question doesn't fit your view of "programming-related" could you please provide an alternate forum for this in a comment when you cast your close vote? Thanks!

  • How do I bind a key to "the function represented by the following key sequence"?

    - by katrielalex
    I'm just starting to learn emacs (woohoo!) and I've been mucking around in my .emacs quite happily. Unfortunately, I don't know Lisp yet, so I'm having issues with the basics. I've already remapped a few keys until I fix my muscle memory: (global-set-key (kbd "<f9>") 'recompile) That's fine. But how can I tell a key to 'simulate pressing several keys'? For instance, I don't know, make <f1> do the same as C-u 2 C-x } (widen buffer by two chars). One way is to look up that C-x } calls shrink-window-horizontally, and do some sort of lambda thing. This is of course the neat and elegant way (how do you do this?). But surely there's a way to define <f1> to send the keystrokes C-u 2 C-x }?

  • Is there a better way than a sequence of if's to handle events?

    - by Matt
    I recently ran across several objects implemented to handle events with a hard coded mapping using this pattern: public void handleEvent(Event event) { if(event.getCode() == SOME_STATIC_EVENT) doSomething(event); if(event.getCode() == ANOTHER_STATIC_EVENT) doSomethingElse(event); } where doSomething functions are implemented as methods of the same class. In hopes of striving for looser coupling, how would you suggest abstracting out this pattern? Also, what's the best approach for mapping 0..N functions to a fired event?

  • possible to show composition relationship in a diagram generated from PHP source code?

    - by ajsie
    i have tested several UML applications for whether they could show composition relationships in the UML diagrams generated form the PHP source code or not, and the result is they can't. i know that this is a typical problem for PHP cause we don't declare a data type when we code, so it's difficult for the UML applications to know if an instance variable is a reference to an object or not. i also tested nWire with the same result. will there never be applications that could show us a complete map over all object relationships more than just inheritance? i think it's a pity that you can't have a good view over all the relationships for an application. cause when i use an open source solution, i always want to know how the objects are related to each other. maybe we could make comments for the instance variable telling the software that this is an reference to an object? but that would mean that the mapping software is using this solution. i feel its a pity nWire/visual paradigm can't give us a complete map:(

  • VB6 ActiveX exe - what is the proper registration sequence?

    - by Timbuck
    I have recently updated a Visual Basic 6 application that is an ActiveX exe, running on Windows XP. I have a couple of testers for this application who have received a copy of the exe and are attempting to run it. However, they are getting an error message "Unexpected error;quitting" when trying to do so. A key difference between their testing and my testing is that on the machines I tested on, I have admin rights and was able to register the application using the appname.exe /regserver command line. Reading the details at MS Support about file registration appears unclear: Visual Basic ActiveX EXE files register themselves the first time you run the EXE. However, you cannot use the EXE as a COM server until it is registered. So does this mean that after the first time the users run the exe that the application should be correctly registered, and the error I am receiving is sign of something other than an incorrectly registered application? Or does this mean that the application will not work properly until such time as the file is explicitly registered using the appname.exe /regserver command line? nb - during a production distribution, the software would be sent out to client PCs using Systems Management Server, which isn't an option for this testing.

I can do: (select #(and (>= % x) (< % y)) xs) But this is inefficient - O(n) when it could be O(log n), I expect the number of elements returned to be small. Using take-while and drop-while would let me exit once I've reached y, but I still can't jump to x efficiently.

  • What is the "un-tab" sequence in (g)Vim?

    - by OwenP
    This is an annoyance I've had for a long time. (Nitpicky section: I prefer 4 space characters to tab characters. It's a lot easier to type "tab" instead of explaining that. When I say "tab", I mean "the action that happens when you press the tab key" which is probably more simply stated as "increase indentation".) I'm using smartindent while editing a document where indentation has some significance. In "dumb" windows text editors I can press Shift+Tab to remove a tab or, more appropriately, decrease the indentation level of the current line. I can't figure out how to do this from edit mode in Vim; Shift+Tab seems to count just the same as Tab. I know in Command mode << will decrease indentation. I want the equivalent in edit mode. These are the solutions I've found so far and why I don't like them, one in particular may be the key to the answer. Use Notepad++ or some other dumb editor. I've done this for a couple of years but I really miss Vim. Exit edit mode, use <<, enter edit mode. This just puts the cursor at column 0; if I wanted this I wouldn't have tried smartindent. Stop using smartindent. I don't decrease indent as often as I need to keep the same indent level; this would be a loss of productivity. The left arrow key seems to decrease the indent by one level. I'd rather something I can do without leaving the home row. This is the most promising choice. Maybe there's an option I can set? Maybe I can rebind left arrow to something? (If it requires rebinding please explain in detail; I've never delved into reconfiguring (g)Vim.

  • MySQL password changed every other day in windows?

    - by PHP
    Every morning when I check server status,I will find MySQL's password is changed: mysql -uuser -ppassword will report ERROR 1045 (28000): Access denied for user 'user'@'localhost' (using password: YES) And then I restart server,and when it's up,MySQL will be back to normal.
