• "Punch card" application

  - by icelava

  Our main-con manager is looking for a "punch card" type of attendance-logging application. We need to take attendance every day, and the most "automatic" method is simply to track when people unlock their Windows desktop screen (not logon, because many simply leave the computer on indefinitely), and report to a remote location/repository, where the administrator will be able to observe which users unlocked their screens each day. Has anybody come across such an application suite? It likely has to be a Windows service so that it operates regardless of who is logged into the system.

• Encrypt Data Prior to Upload

  - by TheW

  I'm looking to store some data online but I want to encrypt the files first. Since I understand that sFTP will only encrypt the transmission of the data, I'm wondering what program others use to encrypt their files prior to sFTPing them to a backup server. Thanks.

• How would you structure your entity model for storing arbitrary key/value data with different data t

  - by Nathan Ridley

  I keep coming across scenarios where it will be useful to store a set of arbitrary data in a table using a per-row key/value model, rather than a rigid column/field model. The problem is, I want to store the values with their correct data type rather than converting everything to a string. This means I have to choose either a single table with multiple nullable columns, one for each data type, or a set of value tables, one for each data type. I'm also unsure as to whether I should use full third normal form and separate the keys into a separate table, referencing them via a foreign key from the value table(s), or if it would be better to keep things simple and store the string keys in the value table(s) and accept the duplication of strings. Old/bad: This solution makes adding additional values a pain in a fluid environment because the table needs to be modified regularly. MyTable ============================ ID Key1 Key2 Key3 int int string date ---------------------------- 1 Value1 Value2 Value3 2 Value4 Value5 Value6 Single Table Solution This solution allows simplicity via a single table. The querying code still needs to check for nulls to determine which data type the field is storing. A check constraint is probably also required to ensure only one of the value fields contains non-nulll data. DataValues ============================================================= ID RecordID Key IntValue StringValue DateValue int int string int string date ------------------------------------------------------------- 1 1 Key1 Value1 NULL NULL 2 1 Key2 NULL Value2 NULL 3 1 Key3 NULL NULL Value3 4 2 Key1 Value4 NULL NULL 5 2 Key2 NULL Value5 NULL 6 2 Key3 NULL NULL Value6 Multiple-Table Solution This solution allows for more concise purposing of each table, though the code needs to know the data type in advance as it needs to query a different table for each data type. Indexing is probably simpler and more efficient because there are less columns that need indexing. IntegerValues =============================== ID RecordID Key Value int int string int ------------------------------- 1 1 Key1 Value1 2 2 Key1 Value4 StringValues =============================== ID RecordID Key Value int int string string ------------------------------- 1 1 Key2 Value2 2 2 Key2 Value5 DateValues =============================== ID RecordID Key Value int int string date ------------------------------- 1 1 Key3 Value3 2 2 Key3 Value6 How do you approach this problem? Which solution is better? Also, should the key column be separated into a separate table and referenced via a foreign key or be should it be kept in the value table and bulk updated if for some reason the key name changes?

• Java: Convenient way to refactor the application.

  - by Harshal

  Hi, Everyone We have an agile enterprise application built on JSP and Servlet without any design strategy. This application was built in early 2002 considering 1000 users. After 2002, we received lots of requests from the marketing partners. Currently, the application has lots of spaghetti code with lots of Ifs and elses. One class has more than 20,000 lines of code with a huge body of functions without abstraction. Now, we need to support billions of records, what we need to do immediately and gradually? We have to refactor the application? Which framework, we need to use? How the usage of the framework will be helpful to the end users? How to convince the leaders to do the refactoring? How to gain the faster response time as compare to the current system?

• WAS Non-HTTP activation - hooking application startup

  - by Mike Tours

  I'm trying to integrate a netTcpBinding based application that is hosted inside WAS with an IoC container (autofac/spring). Unfortunately, when it starts inside WAS and due to the fact that it is not an Http based application, no events are fired inside the Global application class. I need to catch the application domain startup so that I can configure the IoC container. Is there any way to do this when hosting in WAS? I've seen horrible things involving using static classes inside App_Code folders, but I'd like something somewhat more testable and not quite as dirty.

• How to make my Java Swing application a Client-Server application?

  - by Jonas

  I have made a Java Swing application. Now I would like to make it a Client-Server application. All clients should be notified when data on the server is changed, so I'm not looking for a Web Service. The Client-Server application will be run on a single LAN, it's a business application. The Server will contain a database, JavaDB. What technology and library is easiest to start with? Should I implement it from scratch using Sockets, or should I use Java RMI, or maybe JMS? Or are there other alternatives that are easier to start with? And is there any server library that I should use? Is Jetty an alternative?

• Application self aware of external database record modifications.

  - by Khou

  How do you make your application aware that a database record was changed or created by an external application rather than the application itself? Do you add a special check sum to the database record or what do you do to stop external changes to the database? (in case it was hacked and the hacker decides to add a new record or change an existing database record)

• frequent updates of a Tomcat application

  - by Erel Segal Halevi

  I have an application that runs on a Tomcat 7 server on a Windows machine. In its current stage, I have to frequently update and fix it. Whenever I need to update the application, I do all this: Build a new war file; Go to the Windows server, stop the Tomcat service; download the file, put it under webapps; Remove the old application folder under webapps; Remove the old application folder under work/Catalina/localhost (otherwise it keeps the old version cached). Restart the Tomcat service. I am sure there is a way to do all this automatically. What is it?

• Windows Software to Save Arbitrary Application State

  - by ashes999

  VM software does a great job of saving state when you "turn it off," allowing instant and immediate return to that previous state. Is there some application for Windows that allows me to do the same thing, for any arbitrary software? It would allow me to save/restore state, possibly via a shell command or button that it appends to every window. Edit: For clarity, there are two types of apps: those that save their own states, and those that save others' states. Those that save their own state are like Chrome, which on load, reloads the windows you had open last time. That's not what I'm asking about; I'm asking for an app that can save the state of other apps, kind of like VM software does; but for any app. (A trivial test would be load notepad++, type a bunch of stuff, and save-state; on reset-state, you should be able to multi-level undo a lot of what you wrote, as if you never shut down the application.)

• Checking deployed port in ruby on rails application

  - by john chan

  Is there an elegant way to check which port you deployed a ruby on rails application using mongrel? I could not find a directive (i.e. such as #{RAILS_ROOT} which contains the root directory of the application) that I can use to perform a check. I need this to do a check since I am deploying the same application on different ports and I need the app to do different things according to the port that is being accessed. Any help would be appreciated, Thanks

• RSpec setup for an application that depends on an external database from another application.

  - by Chris Rittersdorf

  I've had to add features to an application that depends on a database from another application. I've been able to set up a connection to this external database and pull data from it. However, I'm not sure how to get my main application to create a test database for this external application. It would be awesome if there some way to pull in the schema for this database and create it in the same manner that 'rake db:test:prepare' does. Is there any configuration capabilities for RSpec to do this, or will I have to roll my own task?

• Developing multiple user interfaces for an application

  - by denizkocak

  I want to develop an application which has a graphical user interface that could be developed by using different widget toolkits. For example I want to use Qt, GTK+ or even ncurses as a building block for my user interface for the same application. Moreover users could choose which GUI implementation will be used during the next startup of the application without recompiling it first. I wonder what are possible design strategies and design patterns used in the implementation of this design?
