  • How to know when a specific process is stuck?

    - by Carlos Blanco
    Is there a way to know when a specific process is "stuck" in Java? I'm running an external application from my java program. Sometimes, this app hangs. I would like to know when this app stops working so I can kill it from my code. I'm thinking of some type of monitoring from a different thread in my code. Any toughts?

I need something like this http://en.wikipedia.org/wiki/File:LampFlowchart.svg

  • How do software projects go over budget and under-deliver?

    - by Carlos
    I've come across this story quite a few times here in the UK: NHS Computer System Summary: We're spunking £12 Billion on some health software with barely anything working. I was sitting the office discussing this with my colleagues, and we had a little think about. From what I can see, all the NHS needs is a database + middle tier of drugs/hospitals/patients/prescriptions objects, and various GUIs for doctors and nurses to look at. You'd also need to think about security and scalability. And you'd need to sit around a hospital/pharmacy/GPs office for a bit to figure out what they need. But, all told, I'd say I could knock together something with that kind of structure in a couple of days, and maybe throw in a month or two to make it work in scale. If I had a few million quid, I could probably hire some really excellent designers to make a maintainable codebase, and also buy appropriate hardware to run the system on. I hate to trivialize something that seems to have caused to much trouble, but to me it looks like just a big distributed CRUD + UI system. So how on earth did this project bloat to £12B without producing much useful software? As I don't think the software sounds so complicated, I can only imagine that something about how it was organised caused this mess. Is it outsourcing that's the problem? Is it not getting the software designers to understand the medical business that caused it? What are your experiences with projects gone over budget, under delivered? What are best practices for large projects? Have you ever worked on such a project?

  • Delete all previous records and insert new ones

    When updating an employee with id = 1 for example, what is the best way to delete all previous records in the table certificate for this employee_id and insert the new ones?. create table EMPLOYEE ( id INT NOT NULL auto_increment, first_name VARCHAR(20) default NULL, last_name VARCHAR(20) default NULL, salary INT default NULL, PRIMARY KEY (id) ); create table CERTIFICATE ( id INT NOT NULL auto_increment, certificate_name VARCHAR(30) default NULL, employee_id INT default NULL, PRIMARY KEY (id) ); Hibernate mapping <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="Employee" table="EMPLOYEE"> <id name="id" type="int" column="id"> <generator class="sequence"> <param name="sequence">employee_seq</param> </generator> </id> <set name="certificates" lazy="false" cascade="all"> <key column="employee_id" not-null="true"/> <one-to-many class="Certificate"/> </set> <property name="firstName" column="first_name"/> <property name="lastName" column="last_name"/> <property name="salary" column="salary"/> </class> <class name="Certificate" table="CERTIFICATE"> <id name="id" type="int" column="id"> <param name="sequence">certificate_seq</param> </id> <property name="employee_id" column="employee_id" insert="false" update="false"/> <property name="name" column="certificate_name"/> </class> </hibernate-mapping>

  • Best use of System.Windows.Forms.Application.Run()

    - by carlos
    Hello i Have a programa that has starts in a main sub, it executes some code and after that code it opens a form using System.Windows.Forms.Application.Run(General) General is a form but also a class, so I wonder what it the pros or cons of using : System.Windows.Forms.Application.Run(General) vs Dim gen as general System.Windows.Forms.Application.Run(gen) In the first I am opening a form using the name of the class, and I read that it is best to declare the instance as an object variable. So far I used the first approach without any problem. Thanks for your comments !

  • Timeout not working in SQL Connection

    - by carlos
    I have this simple code to test that a DB is ready: Function testlocalcon() As Boolean Dim constr As String = _clconstr Try Using t As New SqlConnection() constr = constr & " ; Connect Timeout=1" If Not t.State = Data.ConnectionState.Open Then t.ConnectionString = constr t.Open() If t.State = Data.ConnectionState.Open Then Return True Else Return False End If Else Return True End If End Using Catch ex As Exception Return False End Try End Function I do not want to execute a query, just to check the connection, but no matter what the time out parameter is ignored. I search here (Stackoverflow) and internet and found nothing in how to fix this. Any one else have this problem? Or, are there any other ideas on how to let the application know that the DB is ready?

  • Sharing information between applications

    - by Zé Carlos
    My question is very simple to expose: I have a few aplications that share data between then. I need a way to support that data sharing (cross several computers) and when one aplication changes data, others should be notified about that. My question is about what tecnologies could be usefull to me. The solution i realise at this moment is to have a database to share data and an external publish-subscribe system (like http://pubsub.codeplex.com/) to notify all applications when the data is changed. But i belive that could exist some helpfull solutions. Do you know any of then? Thanks.

  • how to filter text of the selected value in drop down

    - by Carlos
    I have a drop down menu. Has product types. Product types have associated value (from drop down) values correspond to machine groups. So each option should have three variables--Machine name, values, machine group. I can get the Machine name and I can get the machine value (and display them in a different field)...what I have not been able to figure out is how to change the value into the Machine group. jQuery('#MachineName').bind('change', function() { //get selected value from drop down; var selectedValue = jQuery("#MachineName").val(); //populate a text field with the selected drop down value jQuery("#MachineValue").val(selectedValue); What I would like to do is keep that MachineValue but then populate another text field with the sorted MachineGroup I have been trying to run it through something like switch(jQuery(this).val()){ case "236" : newVal = "8"; break; But I don't want to "change" the value I just want to do an "if then" type filter, so maybe something like: '236' => "8", '237' => "5", I just don't know how to properly say "assign the MachineGroup based on the MachineValue" (and then have it populate a different text field) In the end I would have three fields. The drop down, the MachineValue and the MachineGroup. Drop down and value are done, I just need to do Group. (And I can sort Group based on MachineName...just not sure which would be easier)

  • Python unicode problem

    - by Somebody still uses you MS-DOS
    I'm receiving some data from a ZODB (Zope Object Database). I receive a mybrains object. Then I do: o = mybrains.getObject() and I receive a "Person" object in my project. Then, I can do b = o.name and doing print b on my class I get: José Carlos and print b.name.__class__ <type 'unicode'> I have a lot of "Person" objects. They are added to a list. names = [o.nome, o1.nome, o2.nome] Then, I trying to create a text file with this data. delimiter = ';' all = delimiter.join(names) + '\n' No problem. Now, when I do a print all I have: José Carlos;Jonas;Natália Juan;John But when I try to create a file of it: f = open("/tmp/test.txt", "w") f.write(all) I get an error like this (the positions aren't exaclty the same, since I change the names) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 84: ordinal not in range(128) If I can print already with the "correct" form to display it, why I can't write a file with it? Which encode/decode method should I use to write a file with this data? I'm using Python 2.4.5 (can't upgrade it)

  • Virtual Hard Drive not booting - VMWare

    - by Chloraphil
    I have a .vmdk (VMWare hard disk) file that I cannot use as the lone disk in a new virtual machine. If I attach it to an existing virtual machine then it works fine. It has Windows Server 2003 on it. When I attempt to boot the new VM it attempts a network boot. EDIT: VMWare Workstation 6.5 I could not find a PXE option in the settings, and I did look in the VM config file for "PXE" but did not find one.

  • How do I remove the selected tag filter when searching for Unanswered questions on Superuser?

    - by orangechicken
    I've been looking for unanswered questions trying to build some reputation here. Once I select a tag filter in the sidebar, I'm shown all of the questions with that tag. Choosing more tags makes the filter more specific and choosing one of the tags from the set I've already chosen replaces the whole set with that one tag. But, how do I remove that lone tag so that I can return to the full list of Unanswered questions?

  • Tester-Developer communication

    - by HH_
    While a lot is written about developer-developer, developer-client, developer-team manager communications, I couldn't find any text which gives guidelines about tester-developer communication and relation. Whether testers and developers are separate teams or in the same one (in my case, I am a lone tester in an agile development project), I have the belief that how testers are perceived is extremely important in order for testing to be well-accepted, and to serve its goal in enhancing the quality of the project (for example, they should not be viewed as a police force). Any advices, or studies about how a tester should communicate with developers? Thank you

  • mysql join with multiple values in one column

    - by CYREX
    I need to make a query that creates 3 columns that come from 2 tables which have the following relations: TABLE 1 has Column ID that relates to TABLE 2 with column ID2 In TABLE 1 there is a column called user In TABLE 2 there is a column called names There can be 1 unique user but there can be many names associated to that user. If i do the following i get all data BUT the user column repeats itself for each name it has associated. What i want is for use to appear unique but the names columns appear with all the names associated to the user column but separated by commas, like the following: select user,names from TABLE1 left join TABLE2 on TABLE1.id = TABLE2.id This will show the users repeated everytime a name appears for that user. what i want is to appear like this: USER - NAMES cyrex - pedrox, rambo, zelda homeboy - carmen, carlos, tom, sandra jerry - seinfeld, christine ninja - soloboy etc....

  • We Are SQLFamily

    - by AllenMWhite
    On Monday, Tom LaRock ( b /@sqlrockstar) presented his #MemeMonday topic as What #SQLFamily Means To Me . The #sqlfamily hash tag is a relatively new one, but is amazingly appropriate. I've been working with relational databases for almost 20 years, and for most of that time I've been the lone DBA. The only one to set things up, explain how things work, fix the problems, make it go faster, etc., etc., yadda, yadda, yadda. I enjoy being 'the guy', but at the same time it gets hard. What if I'm wrong?...(read more)

  • What percentage of software developers work solo?

    - by JMather
    I'm trying to put together some ideas for a talk, and one of the things that occurred to me, is if there's any documentation or research into how many programmers work as the lone developer within their team. I think this is an important distinction because individual developers (and perhaps small team developers) end up having to wear many more hats than developers part of a large developer group. It could give us some better insight to career development and transition tactics, as well. I've tried some generally googling, and wasn't able to turn up anything, so I'm hoping maybe someone has seen (or studied) something related to this. Thanks in advance!
