  • Know any unobstrusive, simple GUI guidelines or design recommendations for notifications?

    - by Vinko Vrsalovic
    Hello again. I'm in the process of designing and testing various ideas for an application whose main functionality will be to notify users of occurring events and offer them with a choice of actions for each. The standard choice would be to create a queue of events showing a popup in the taskbar with the events and actions, but I want this tool to be the less intrusive and disrupting as possible. What I'm after is a good book or papers on studies of how to maximize user productivity in these intrinsically disruptive scenarios (in other words, how to achieve the perfect degree of annoying-ness, not too much, not too little). The user is supposedly interested in these events, they subscribe to them and can choose the actions to perform on each. I prefer books and papers, but the usual StackOverflow wisdom is appreciated as well. I'm after things like: Don't use popups, use instead X Show popups at most 3 seconds Show them in the left corner Use color X because it improves readability and disrupts less That is, cognitive aspects of GUI design that would help users in such a scenario.

  • Best practices for developing bigger applications on Android

    - by Janusz
    I've already written some small Android Applications, most of them in one Activity and nearly no data that should be persistent on the device. Now I'm writing an application that needs more Activities and I'm a bit puzzled about how to organize all this. My app will download some data parse it show it to the user and then show other activities depending on the data and the user interaction. Some of that data could be cached, some of it has to be downloaded every time. Some of that data should not be downloaded freshly at the moment the orientation changes, but it should on the moment the activity is created... Another thing I'm confused about are things like a httpClient. I now for example create a new httpclient for every activity, the same thing for locationlisteners. Are there books, a blogs or documentations with patterns, examples and advice on organizing larger apps build on android? Everything I found until now are get startet tutorials leaving me alone after 60 lines of code...

  • Is it worth moving from stored procedures to linq ?

    - by Josef
    I'm looking at standardizing programming in an organisaiton. Half uses stored procedures and the other half Linq. From what i've read there is still some debate going on on this topic. My concern is that MS is trying to slip in it's own proprietry query language 'linq' to make SQL redundant. If a few years back microsoft had tried to win customers from oracle and sybase with their MSSQL database and stated that it didn't use SQL by their own proprietry query langues ie linq. I doubt many would have switched. I believe that is exactly what is happening now by introducting it into the applicaiton business layer. I have used MS for many years but there is one gripe that I have with them and that is that they change their direction a lot. By a lot I mean new releases of .net, silverlight etc are more than 30% different from previous version. So by the time you become productive a new release is on the way. As things stand now a web developer using .net would need to know either vb.net or c#, xml, xaml,javascript,html, sql and now linq. That doesn't make for good productivity in my books. My concern is that once we all start using linq MS will start changing it between releases. and it will become an ever changing landscape. I believe that 'linq to sql' has already been deprecated. At leas with SQL we are dealing with a more stable and standardized language. Are we looking at a programming revolution or a marketing campaign? As far as I know other languages like Cobol have stayed the same for years. A cobol program from 20 years ago could pick up todays code and start working on it. Could a Vb3 person work on a modern .net web app ? Would these large changes need to be made if the underlying original foundation had been sound ? I worry about following MS shaking roadmap with it's deadends and double backs. are there any architects out there who feel the same ? regards Josef

  • Why "Algorithms" and "Data Structures" are treated as separate disciplines?

    - by Pavel Shved
    This question was the last straw; and I've been wondering for a long time about it, Why do people think about "Algorithms" and "Data structures" as about something that can be separated from each other? I see a lot of evidence that they're separated in programmers' minds. they request "Data Structures & Algorithms" books they refer to "Data Structures" and "Algorithms" as separate university courses they "know Algorithms", but are "weak in Data Structures" (can't find the link, sorry). etc. In my opinion "Data Structures" are algorithms, since the concept of "Data Structure" is about Algorithms to operate data that go in and out of the structures. But the opinion seems not a mainstream. What do I miss?

  • Would Ruby on Rails be appropriate for this Foreign Language project?

    - by Lynne Overesch-Maister
    I'm a Spanish professor & computer groupie. About 15 years ago, I authored in HyperCard a series of verb conjugation programs that are now completely out of date with respect to System OS X. I would like to redo these programs myself because I had a lot of fun doing them last time (mostly I coded while my son played in Leaps and Bounds, you know, one of those places where parents take their kids & let them run wild through the tubes...). Colleagues have mentioned using Flash, Director, and various other solutions, but I saw a presentation on RoR at our SIDLIT conference today, and was inspired. I will be parsing and comparing strings (and there are other features on top of that, but that is the main one), "adding" strings relationally indexed in some kind of database(s). It will also have to handle various foreign characters (accents, upside down question marks, etc.). On top of the main process of the program, it will have to provide a practice vs. test mode, keep track of specific answers as well as totals right/wrong, and print a report. Would this be either easier and/or more efficiently done in RoR than in other languages. I am pretty sure that it will work on a Microsoft server, right? Because I think that is where most of our stuff is. I would be programming either on a Mac or a PC, whichever you think is easier. So, in summary, is RoR the way for me to go with this project? If I have some (little) experience programming in Hypercard and C, should I be able to pick RoR up fairly quickly? What things will I need to start (I already saw something called Redhills foreign key migration plugin, which I assume would be beneficial)? I still have my old scripts from hypercard, however what I would really like to do is to combine all six of my former tense-specific programs into one larger program. I figure that it wouldn't be too hard to reference the individual tenses in some way--could that be a class? Many thanks for any help you can give me on this forum.

  • Getting ready to learn html5

    - by vtortola
    I'm a desktop application developer, and I plan learning html5, but as it's not released, there are (almost) no published books and not too much infomation for beginners on the web... I feel I should start with html4 and the current web development skills. I think I should start with html4, css, and javascript... but there are so many technologies related that I get lost :D So, what current technologies will be still used when html5 is released? I mean, what about "jquery" and "ajax"? I know they are javascript under the hood, but will they still make sense in the future? What would you recommend me considering that I have just a little bit of html knowlegde, almost null CSS and completely null in javascript?

  • Windows Media Player Device Sync in VB.NET using WMPLIB

    - by Jack Hayter
    The MSDN documentation for WMPLIB states that syncing to device is not supported in .NET programming, only C++. Is there, however, a simple wrapper class or DLL that can be used to interface between a .NET program and the nescessary C++ code? Or is there a better way to sync files to a device using VB.NET? Are all devices suited/compatible with just a simple filesystem.copyfile ?

  • Wordpress auto-generated "canonical" links - how to add a custom URL parameter?

    - by kiko
    Hello - Does anyone know how to modify the Wordpress canonical links to add a custom URL parameter? I have a Wordpress site with a page that queries a separate (non-Wordpress) database. I passed the URL parameter "pubID" to display individual books and it is working OK. Example: http://www.uglyducklingpresse.org/catalog/browse/item/?pubID=63 But the individual book pages are not showing up properly in Google - the ?pubID parameter is stripped out. I think maybe this is because all the item pages have the same auto-generated "canonical" URL link tag in the source - one with the "pubID" parameter stripped out. Example: link rel='canonical' href='http://www.uglyducklingpresse.org/catalog/browse/item/' Is there a way to perhaps edit .htaccess to add a custom URL parameter to Wordpress, so that the parameter is not stripped out by permalinks and the "canonical" links? Or maybe there's another solution ... Thank you for any ideas!

  • Google and Mirror Websites

    - by Roberto Aloi
    Which is the best way to manage a website with one or more mirrors so that: Google don't consider it as "dupicated content" The website is correctly indexed No inconsistencies or duplicated information are present in Google Analytics The Google webmaster guidelines in general are respected NOTE: I'm not sure if I should ask this question here or in ServerFault. It looks a bit in the middle between programming and server administration. Let me know if you think ServerFault represent a more appropriate place for this and I'll move it. Thanks.

  • read url in binary mode in java

    - by Andrew Zawok
    In java I need to read a binary file from a site and write it to a disk file. This example http://java.sun.com/docs/books/tutorial/networking/urls/readingURL.html could read webpages succesfully, but when I try to read a binary file from my localhost server and write it to a disk file the contents change, corrupting the binary file. Using fc I see that 0x90 is changed to 0x3F and other changes. How do I acess the binary files (read url and write to file) without java or anything else changing ANY characters, like doing any newline conversions or character conversions or anything else, simply reading input url and writing it out as a file.

  • RTS AI: where to start?

    - by awegawef
    I'd like to begin tinkering around with an RTS AI, but I'm having trouble finding a good environment to work with, ie a game that has been already created. I have looked at Spring RTS and Bos Wars, but they don't seem to be conducive to creating simple examples. I am not totally opposed to writing my own game environment, it would just take a long time. Does anyone have a suggestion as to how I can get my feet wet without programming my own game?

  • Better C# Syntax Coloring for Visual Studio 2010?

    - by Oak
    Coming from Eclipse, I'm disappointed with the very limited syntax coloring capabilities offered for C# by Visual Studio (all versions, up to 2010). In particular, I'm interesting in distinct coloring for methods / fields / locals / static stuff. I'm aware Visual Assist can enhance the coloring, but I've failed to find any free alternative capable of doing that, so I'm turning to SO (I hope it's programming-related enough). Is there any free (or at least cheaper than Visual Assist) solution capable of enhancing the syntax coloring for C#?
