  • Gesture Based NetBeans Tip Infrastructure

    - by Geertjan
    All/most/many gestures you make in NetBeans IDE are recorded in an XML file in your user directory, "var/log/uigestures", which is what makes the Key Promoter I outlined yesterday possible. The idea behind it is for analysis to be made possible, when you periodically pass the gestures data back to the NetBeans team. See http://statistics.netbeans.org for details. Since the gestures in the 'uigestures' file are identifiable by distinct loggers and other parameters, there's no end to the interesting things that one is able to do with it. While the NetBeans team can see which gestures are done most frequently, e.g., which kinds of projects are created most often, thus helping in prioritizing new features and bugs, etc, you as the user can, depending on who and how the initiative is taken, directly benefit from your collected data, too. Tim Boudreau, in a recent article, mentioned the usefulness of hippie completion. So, imagine that whenever you use code completion, a tip were to appear reminding you about hippie completion. And then you'd be able to choose whether you'd like to see the tip again or not, etc, i.e., customize the frequency of tips and the types of tips you'd like to be shown. And then, it could be taken a step further. The tip plugin could be set up in such a way that anyone would be able to register new tips per gesture. For example, maybe you have something very interesting to share about code completion in NetBeans. So, you'd create your own plugin in which there'd be an HTML file containing the text you'd like to have displayed whenever you (or your team members, or your students, maybe?) use code completion. Then you'd register that HTML file in plugin's layer file, in a subfolder dedicated to the specific gesture that you're interested in commenting on. The same is true, not just for NetBeans IDE, but for anyone creating their applications on top of the NetBeans Platform, of course.

  • How to implement string matching based on a pattern

    - by Vincent Rischmann
    I was asked to build a tool that can identify if a string match a pattern. Example: {1:20} stuff t(x) {a,b,c} would match: 1 stuff tx a 20 stuff t c It is a sort of regex but with a different syntax Parentheses indicate an optional value {1:20} is a interval; I will have to check if the token is a number and if it is between 1 and 20 {a,b,c} is just an enumeration; it can be either a or b or c Right now I implemented this with a regex, and the interval stuff was a pain to do. On my own time I tried implementing some kind of matcher by hand, but it turns out it's not that easy to do. By experimenting I ended up with a function that generates a state table from the pattern and a state machine. It worked well until I tried to implement the optional value, and I got stuck and how to generate the state table. After that I searched how I could do this, and that led me to stuff like LL parser, LALR parser, recursive-descent parser, context-free grammars, etc. I never studied any of this so it's hard to know what is relevant here, but I think this is what I need: A grammar A parser which generates states from the grammar and a pattern A state machine to see if a string match the states So my first question is: Is this right ? And second question, what do you recommend I read/study to be able to implement this ?

  • Internationalization messages based in views or in model entities

    - by SJuan76
    I have a small webapp in java and I am adding the internationalization support, replacing texts with labels that are defined in dictionary files. While some texts are obviously unique to each view (v.g. the html title), other refer to concepts from the model (v.g. a ticket, the location or status of such ticket, etc.) As usual, some terms will appear many times in different locations (vg, in both the edition page and in the search page and in the listings I have a "ticketLocation" label). My question is: can I organize the labels around the model concepts (so I have a ticket.location label and I use it everywhere such field is labeled) or should I make a different label for each (so form.ticketLocation and filter.ticketLocation and list.ticketLocation). I would go for the first option; I have searched for tips and the only thing that I see that could hinder me is due to the length of the string disrupting the design, and even for that I would prefer having to add a ticket.locationShort for places where there is not much space. What is your opinion/tips/experience?

  • Event-Driven Debugging

    - by Brian Donahue
    Most application troubleshooting involves getting an error, analyzing the error message, and at worst, attaching a debugger to work out the real cause. What is not really covered is how to troubleshoot an applicaiton that is not errant, but is having a performance issue, and more than likely, in the middle of the night when you are snug in your bed, sawing logs. What you need is an ever-vigilant cyborg who never sleeps to sit in front of your server all night, but as SkyNet is not live yet, you can settle for the next-best thing. Windows provides performance counters and alerts that can tell you when an applicaiton reaches an unacceptable threshold of naughty behavior, but although it can tattle on your brainchild, it won't be the child psychiatrist that you need to tell you why he's pulling your server's pigtails and pulling faces at the teacher. What you need is to plug a debugger into performance monitor and have it tell you what's going on with your applicaiton at the time. For this purpose, I'd used Microsoft's MDbgEngine as the basis for an applicaiton that will dump a program's stacks, I call it Application Slicer Dicer Wonder Dumper Super Cyborg, or StackOMatic for short. StackOMatic can look at a program's behavior and tell you if the stacks are not moving, but it can also work on the command-line to dump all managed methods on the stack at will. Now that there is a command you can use to dump the stacks, all you need to do is politely tell Windows to run it when you're displeased with your creation as it's trashing the CPU of your server at 3 AM. The first step is to create a scheduled task to tell StackOMatic to dump your applicaiton. Start Task Scheduler and right-click Task Scheduler Library and then Create Task. For this exercise I'm creating a task that will dump the Red Gate SQL Monitor Base Monitor Service. In the Actions tab, I enter the path to StackOMatic and use the arguments to log the stack dump to a file: /PN:RedGate.Response.Engine.Alerting.Base.Service /OUT:c:\users\administrator\MonitorLog.txt Next, I go into Windows Server 2008's Reliability and Performance Monitor and add a new Data Collector Set. This set will produce an alert on the %Processor Time for the service. When the processor time breaches 50%, it will run the StackDumpBaseService task I created. Whenever the service misbehaves, it will append to the log file. Now when I go to work in the morning, I can see what the service was doing when it overloaded the processor and take action.

  • Checking a record is due based on the 'occuring' field

    - by andy
    I have records that have dates against them and an occurring field that contains none,yearly and monthly id status note date last_updated occurring 1 open --- 01/01/2011 01/02/2010 yearly 2 open --- 05/05/2011 03/05/2011 monthly 3 open --- 06/06/2011 05/06/2011 none Now I need to be able to check if a record is due (the date set has passed) which works perfect if occurring is set to none but I'm unsure of how to approach it when it's set to yearly or monthly (IE: This day in the year/month has passed) So with the above records, if I had a method on the record called due? providing the status is 'open' it needs to return true every year when it's passed that date if it's not been updated within the year yet. I apologise if this is confusing but it's melting my brain just trying to think of it, let alone put it into words.

  • Microsoft Secret Event: New Tablet Unveiling?

    If you read the headline, you know what everyone thinks it will be: a new tablet computer, that Microsoft will manufacture from beginning to end. Apparently, the company believes it will be better able to compete against Apple if it controls both the hardware and the software. But why choose this location for the announcement? Wired thinks it makes sense if the tablet features Xbox live streaming. That would turn the humble device into something of a media machine. Speaking of the device itself, what kind of specs will this hypothetical tablet have? It's hard to say. Microsoft boasts software...

  • Model Based Apps and Frameworks

    Having been involved (mostly as a user or observer) with several recent applications and frameworks, Ive come to the conclusion that building your app/framework on an internal model is generally the best way to go.  In this post Ill explain what I mean by on an internal model and later describe the benefits I have seen, realized, been told about by others and still others that Ive only imagined (but are still possible).  I plan on writing a few blog posts along these lines to explore what...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Exclude pages from search results based on device class (mobile/desktop)

    - by user32224
    We're currently building a new responsive website. While working on the site map, we figured that we don't want to show certain sections on mobile devices. This can be easily done by hiding the navigation parts using CSS/media queries. However, the trouble is that the hidden sites would still show up in search engine results. If a user happens to click on one of these links she might happen to see a badly formatted page as we'd use desktop/tablet only code to show images and video. Is there any way influence the search engines to exclude certain pages if the search is done on a mobile device? Do search engines crawl pages once or with a device specific view twice? Could we set a noindex meta tag for a specific device class?
