  • Nice network diagram editor?

    - by Nicolas Raoul
    Writing a commercial proposal, I want to create a nice graphic showing the clients the architecture I thought of for their IT network, with servers, network connections, firewall, load-balancing, etc. For years I have been using dia, but I am tired of it because: the results are not satisfying, very few network elements are available, and each element's graphic representation is really ugly. Question: How to create nice network diagrams? If a better set of elements was available for dia, that would be a solution.

  • How would one run a task sequence within a task sequence in SCCM 2012 SP1

    - by BigHomie
    A Shining Example: Inside all of my task sequences I have a group that installs driver packages conditionally based on computer model: And of course, this list does nothing but grow. The fact that it grows isn't a big deal, what is a big deal is that every time it changes I have to manually copy and paste those changes across every task sequence I have, which of course leaves huge room for human error. The same goes for other groups of tasks that are common across task sequences. Looking for a solution where I could centrally manage these tasks, be it link other task sequences to a group within another task sequence, or create a separate task sequence and link to that. I came across a solution by John Marcum (SCCM MVP) that mentioned this ability, but this was a while ago and I can't find the link to it anymore to see if it's even still being updated/maintained, but I'm looking for more of a free solution, or even using Powershell or the ConfigMgr SDK is fine with me, I'm no stranger to either.

  • Is there a tool to do round trip software engineering between a sequence diagram and a group of objects that message back and forth?

    - by DeveloperDon
    Is there a tool to do round trip software engineering between a sequence diagram and a group of objects that message back and forth? Perhaps this seems a little exotic, but it seems like a function that includes message calls or even method invocations on other objects could be automatically converted to a sequence diagram given that it is not hard to do manually. Similarly, when a sequence diagram is modified, based on the message name and type of message, should it not be possible to add a message or method to the calling object?

  • Calling next value of a sequence in jpa

    - by Javi
    Hello, I have a class mapped as an Entity to persist it in a database. I have an id field as the primary key so every time the object is persisted the value of the id is retrieved from the sequence "myClass_pk_seq", a code like the following one. @Entity @Table(name="myObjects") public class MyClass { @Id @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="sequence") @SequenceGenerator(name="sequence", sequenceName="myClass_pk_seq", allocationSize=1) @Column(name="myClassId") private Integer id; ... } I need to get the next value of the sequence myClass_pk_seq to reserve that value (get the next value of the sequence and the current value is incremented), but without saving the object. How can I call the next value of a sequence when it's defined like this? Thanks.

  • A good free BON diagram generator?

    - by Audel
    Hello I need to create a static BON diagram which represents a set of clusters, classes and their relationships(inheritance and client-supplier). Does anyone know a good diagram generator I can get for free? The BON diagram is similar to the C sharp's class diagram but this one is generated by Eiffel studio =/ any diagram generators recommendations are welcome ;D Thanks in advance .

  • Increment sequence when updating freebusy in icalendar?

    - by user302038
    I'm new to icalendar, but I couldn't find an answer to this specific situation. My web site has a shared calendar where users can add and update events. They can also indicate on the web site if they will be attending an event. I want to add a button to let them download the calendar as published icalendar events. When they indicated they will be attending an event, I want the event in the icalendar file to be set as "busy", otherwise as "not busy". So I can easily increment the sequence number on the event if the event is changed, but must I increment the sequence number if the user changed whether or not they will attend the event? I don't think that is a "mandatory" reason to increment the sequence, but I'm not sure. What will happen if the user changes their busy status for an event and re-downloads without the sequence number changing? I suppose I can keep a separate sequence number for each time the user changes their attendance status, then add the event sequence number and attendance sequence number together for the "final" event sequence number that's downloaded, but do I have to do it that way?

  • Hibernate sequence should only generate when ID is <=0

    - by Tim Leys
    Hi all, I'm using the folowing sequence in my code. (I got the sequence and @Id @SequenceGenerator(name = "S912_PRO_SEQ", sequenceName = "S912_PRO_SEQ", allocationSize = 1) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "S912_PRO_SEQ") @Column(name = "PRO_ID", unique = true, nullable = false, precision = 9, scale = 0) public int getId() { return this.id; } And using the following sequence / triggers in my DB. CREATE SEQUENCE S912_PRO_SEQ nomaxvalue minvalue 20; CREATE OR REPLACE TRIGGER S912_PRO_B_I_TRG BEFORE INSERT ON S912_project REFERENCING OLD AS OLD NEW AS NEW FOR EACH ROW ENABLE begin IF :NEW.pro_ID IS NULL THEN select S912_PRO_SEQ.nextval into :new.pro_ID from dual; END IF; end; I was wondering if there is a way to let hibernate generate a sequence ONLY if the ID is <=0 (not set) or if the ID already exists. I know for most cases my trigger would fix the situation. But I do not want to rely completely on it. I hope someone can help me out :p

  • Differences between a conceptual UML class diagram and an ERD?

    - by Adam
    If I create a conceptual class diagram such that each class captures 'name' and 'attributes' but not 'operations', have I not basically created what would be otherwise considered an ERD? I'm trying to gain an understanding of what the differences are between creating a conceptual class diagram as I have described versus calling it a ERD? If these are still two different animals, can somebody please explain what the differences are?

  • Weird Excel bar diagram behaviour

    - by Simon
    Hi I have a very simple question. I wanna have a diagram with the following table Apple 30 40 50 Pears 200 300 400 Bananas 10 20 30 The weird thing, when I try to draw a bar diagram the order of the bars change. So Excel draws me first the Bananas, the the pears and finally the apple bar... Is there anyway to tell Excel 2003 that it keeps the order? Thank you very much

  • Specifying distinct sequence per table in Hibernate on subclasses

    - by gutch
    Is there a way to specify distinct sequences for each table in Hibernate, if the ID is defined on a mapped superclass? All entities in our application extend a superclass called DataObject like this: @MappedSuperclass public abstract class DataObject implements Serializable { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) @Column(name = "id") private int id; } @Entity @Table(name = "entity_a") public class EntityA extends DataObject { ... } @Entity @Table(name = "entity_b") public class EntityB extends DataObject { ... } This causes all entities to use a shared sequence, the default hibernate_sequence. What I would like to do is use a separate sequence for each entity, for example entity_a_sequence and entity_b_sequence in the example above. If the ID were specified on the subclasses then I could use the @SequenceGenerator annotation to specify a sequence for each entity, but in this case the ID is on the superclass. Given that ID is in the superclass, is there a way I can use a separate sequence for each entity — and if so, how? (We are using PostgreSQL 8.3, in case that's relevant)

  • create a random sequence, skip to any part of the sequence

    - by Michael Xu
    Hi everyone, In Linux. There is an srand() function, where you supply a seed and it will guarantee the same sequence of pseudorandom numbers in subsequent calls to the random() function afterwards. Lets say, I want to store this pseudo random sequence by remembering this seed value. Furthermore, let's say I want the 100 thousandth number in this pseudo random sequence later. One way, would be to supply the seed number using srand(), and then calling random() 100 thousand times, and remembering this number. Is there a better way of skipping all 99,999 other numbers in the pseudo random list and directly getting the 100 thousandth number in the list. thanks, m

  • How to signal object instantiation in a Collaboration/Communication Diagram?

    - by devoured elysium
    I'd like to know how to translate the following line of code to a Collaboration Diagram: Food food = new Food("abc", 123); I know that I can call an Food's method using the following notation: MyStaticMethod() ----------------------> -------- | | | Food | | | -------- being that equivalent to Taste taste = Food.MyStaticMethod(); and MyInstanceMethod() ----------------------> --------------- | | | food : Food | | | --------------- is equivalent to food.MyInstanceMethod(); but how do I signal that I want to call a given constructor on Food? Thanks

  • oracle sequence init

    - by gospodin
    I wanted to export 3 tables from db1 into db2. Before the export starts, I will create the sequences for those 3 tables. CREATE SEQUENCE TEST_SEQ START WITH 1 INCREMENT BY 1; After the export, I will reinitialize sequnce values to match the max(id) + 1 from the table. CREATE OR REPLACE PROCEDURE "TEST_SEQUENCE" AUTHID CURRENT_USER is v_num number; begin select max(ID) into v_num from TABLE_1; EXECUTE IMMEDIATE 'ALTER SEQUENCE TEST_SEQ INCREMENT BY ' || v_num; EXECUTE IMMEDIATE 'ALTER SEQUENCE 1TEST_SEQ INCREMENT BY 1'; end; / show errors; execute TEST_SEQ; This procedure compiles and executes without problems. But when I want to check t he last value of the sequence, like select TEST_SEQ.nextval from dual; I still get the "1". Can someone tell me why my procedure did not impact my sequence? ps. I am using oracle sql developper to pass sql. Thanks

  • Which Oracle table uses a sequence?

    - by Jaú
    Having a sequence, I need to find out which table.column gets its values. As far as I know, Oracle doesn't keep track of this relationship. So, looking up for the sequence in source code would be the only way. Is that right? Anyone knows of some way to find out this sequence-table relationship?

  • Mapping over sequence with a constant

    - by Hendekagon
    If I need to provide a constant value to a function which I am mapping to the items of a sequence, is there a better way than what I'm doing at present: (map my-function my-sequence (cycle [my-constant-value])) where my-constant-value is a constant in the sense that it's going to be the same for the mappings over my-sequence, although it may be itself a result of some function further out. I get the feeling that later I'll look at what I'm asking here and think it's a silly question because if I structured my code differently it wouldn't be a problem, but well there it is!

  • Modifying y-axis label in pdf Diagram

    - by Andrea
    Hi all, I have mislabelled the y-axis in my pdf graph that I generated from an Matlab file. Unfortuantely, I cant find anymore the data that I used to generate the graph. So I am wondering if there is an free tool that allows me to rename the y-axis in my pdf diagram? Are there any free tools available that could be helpful or is this something "impossible" to do? Many thanks for your help, Andrea

  • Looking for real time collaborative diagram drawing tool

    - by taotree
    I have seen a number of diagram software packages but most don't support real time collaboration. Google docs Drawing does the real-time collaboration, but is severely limited on features--focused on drawing rather than diagrams. I want something that supports connectors and such. Mind maps would be also be nice but would be a secondary requirement.

  • Which should be created first ER Diagram OR Class Diagram?

    - by isthatacode
    The very first step i created a DFD. Then i moved on to create a Class Diagram. And while doing that i felt that i should create the ER diagram first. As there were many details which could not be captured in a Class diagram. So, my question should i create ERD first OR Class Diagrams ? your valuable inputs are appreciated guys!!! thanks for reading

  • xor of sequence of numbers

    - by ArG0NaUt
    You are given with a sequence of natural numbers, you can add any natural number to any number in the sequence such that their xor becomes zero. Your goal is to minimize the sum of added numbers. e.g. Consider the following examples : sequence : 1, 3 answer : 2, adding 2 to 1 we get 3^3=0. sequence : 10, 4, 5, 1 answer: 6, adding 3 to 10 & 3 to 8 we get 13^4^8^1 = 0. sequence : 4, 4 answer : 0, since 4^4 = 0. I tried working on binary representations of sequence number but it got so complex. I want to know if there is any simple and efficient way to solve this problem.

  • Visual Studio UML Sequence Diagram

    - by ikurtz
    I was wondering if there was a Sequence Diagram generator for C#? Im using Visual Studio 2008 Professional. If not is there a quick and simple software? Im finding Enterprise Architect and Visio a bit to cryptic for a beginner. I have found the Class Diagram feature on Visual Studio, which s very useful and am hoping for a equally useful simple program to generate Sequence Diagrams. Thanks.

  • Oracle sequence but then in MS SQL Server

    - by Raymond
    In Oracle there is a mechanism to generate sequence numbers e.g.; CREATE SEQUENCE supplier_seq MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 INCREMENT BY 1 CACHE 20; And then execute the statement supplier_seq.nextval to retrieve the next sequence number. How would you create the same functionality in MS SQL Server ? Edit: I'm not looking for ways to automaticly generate keys for table records. I need to generate a unique value that I can use as an (logical) ID for a process. So I need the exact functionality that Oracle provides.

  • SQL SERVER – 2011 – SEQUENCE is not IDENTITY

    - by pinaldave
    Yesterday I posted blog post on the subject SQL SERVER – 2011 – Introduction to SEQUENCE – Simple Example of SEQUENCE and I received comment where user was not clear about difference between SEQUENCE and IDENTITY. The reality is that SEQUENCE not like IDENTITY. There is very clear difference between them. Identity is about single column. Sequence is always incrementing and it is not dependent on any table. Here is the quick example of the same. USE AdventureWorks2008R2 GO CREATE SEQUENCE [Seq] AS [int] START WITH 1 INCREMENT BY 1 MAXVALUE 20000 GO -- Run five times SELECT NEXT VALUE FOR Seq AS SeqNumber; SELECT NEXT VALUE FOR Seq AS SeqNumber; SELECT NEXT VALUE FOR Seq AS SeqNumber; SELECT NEXT VALUE FOR Seq AS SeqNumber; SELECT NEXT VALUE FOR Seq AS SeqNumber; GO -- Clean Up DROP SEQUENCE [Seq] GO Here is the resultset.

  • Undefined Behavior and Sequence Points Reloaded

    - by Nawaz
    Consider this topic a sequel of the following topic: Previous Installment Undefined Behavior and Sequence Points Let's revisit this funny and convoluted expression (the italicized phrases are taken from the above topic *smile* ): i += ++i; We say this invokes undefined-behavior. I presume that when say this, we implicitly assume that type of i is one of built-in types. So my question is: what if the type of i is a user-defined type? Say it's type is Index which is defined later in this post (see below). Would it still invoke undefined-behavior? If yes, why? Is it not equivalent to writing i.operator+=(i.operator ++()); or even syntactically simpler i.add(i.inc());? Or, do they too invoke undefined-behavior? If no, why not? After all, the object i gets modified twice between consecutive sequence points. Please recall the rule of thumb : an expression can modify an object's value only once between consecutive "sequence points. And if i += ++i is an expression, then it must invoke undefined-behavior. If so, then it's equivalents i.operator+=(i.operator ++()); and i.add(i.inc()); must also invoke undefined-behavior which seems to be untrue! (as far as I understand) Or, i += ++i is not an expression to begin with? If so, then what is it and what is the definition of expression? If it's an expression, and at the same time, it's behavior is also well-defined, then it implies that number of sequence points associated with an expression somehow depends on the type of operands involved in the expression. Am I correct (even partly)? By the way, how about this expression? a[++i] = i; //taken from the previous topic. but here type of `i` is Index. class Index { int state; public: Index(int s) : state(s) {} Index& operator++() { state++; return *this; } Index& operator+=(const Index & index) { state+= index.state; return *this; } operator int() { return state; } Index & add(const Index & index) { state += index.state; return *this; } Index & inc() { state++; return *this; } };
