  • ASP.NET Free Online E-books or tutorials

    - by the_drow
    I need to learn programming ASP.NET with C# but I can't find a good online book to do so. Is there an ASP.NET equivalent to Diving into python? All of the books are quite expensive. I already know Java and C++, are there any major differences between them and C#? If so are there materials that cover only the differences and what I should learn?

  • Developing web sites that imitate desktop apps. How to fight that paradigm? [closed]

    - by user1598390
    Supposse there's a company where web sites/apps are designed to resemble desktop apps. They struggle to add: Splash screens Drop-down menus Tab-pages Pages that don't grow downward with content, context is inside scrollable area so page is of a fixed size, as if resembling the one-screen limitation of desktop apps. Modal windows, pop-ups, etc. Tree views Absolutely no access to content unless you login-first, even with non-sensitive content. After splash screen desapears, you are presented with a login screen. No links - just simulated buttons. Fixed page-size. Cannot open a linked in other tab Print button that prints directly ( not showing printable page so the user can't print via the browser's print command ) Progress bars for loading content even when the browser indicates it with its own animation Fonts and color amulate a desktop app made with Visual Basic, PowerBuilder etc. Every app seems almost as if were made in Visual Basic. They reject this elements: Breadcrumbs Good old underlined links Generated/dynamic navigation, usage-based suggestions Ability to open links in multiple tabs Pagination Printable pages Ability to produce a URL you can save or share that links to an item, like when you send someone the link to an especific StackExchange question. The only URL is the main one. Back button To achieve this, tons of javascript code is needed. Lots and lots of Javascript and Ajax code for things not related with the business but with the necessity to hide/show that button, refresh this listbox, grey-out that label, etc. The coplexity generated by forcing one paradigm into another means most lines of code are dedicated to maintain the illusion of a desktop app. What is the best way to change this mindset, and make them embrace the web, and start producing modern, web apps instead of desktop imitations ? EDIT: These sites are intranet sites. Users hate these apps. They constantly whine about them, but they have to use them to do their daily work. These sites are in-house solutions, the end-users have no choice but to use them. They are a "captive audience". Also, substitution will not happen because of high costs. But at least if that mindset is changed, new developments would be more web-like.

    Is there an IDE for PHP where you can edit the code for your pages online? Real syntax highlighting is minimal. More would be great. I'd like to be able to do development on my site at times other than when I'm not at at home.

  • Tomcat 6 is really UNSTABLE when redeploying web apps

    - by EugeneP
    Do you know how to make it more stable, maybe properties to set, memory to allocate? It always hangs up when redeploying web apps, thru manager (wars), web interface or maven plugin. every second time it gives PermGenSpace, no memory errors etc. on my local machine 3gb ram. It looks like it should be manually set up to work in a stable way. How to fix such a problem?

  • Rules regarding iPhone apps

    - by iphone newbie
    iphone dev has this rule for iphone developers Be certain that the items you offer for purchase do not contain, or relate to, pornography, hate speech, defamation, or gambling (simulated gambling is acceptable). But how come there are apps in the app store such as iBetMate, which, in fact, allows users to gamble? Is there a clause or something that I missed in Apple's rules?

  • 2 Rails Apps, 1 Database (using Heroku)

    - by Paul A.
    I've made 2 apps, App A and App B. App A's sole purpose is to allow users to sign up and App B's purpose is to take select users from App A email them. Since App A & B were created independently & are hosted in 2 separate Heroku instances, how can App B access the users database in App A? Is there a way to push certain relevant rows from App A to App B?

  • Can Django be used for non web apps?

    - by Leeks and Leaks
    I noticed in the main Django introductin they show a feature that maps python objects to the database. This doesn't strike me as being mutually exclusive with with development, is there any reason why this can't be used for non web apps? Is it easy to separate out?

  • Mac Backup Plan

    - by Chuy77
    I'm reviewing my backup plan and would appreciate any thoughts about what more I should do (if anything) to make sure I'm properly covered in case of all hell breaking loose. :-) I have one machine. 1) I run a nightly clone with SuperDuper. I alternate the clone drive weekly so I have two clones, one never more than a week old. 2) I use BackBlaze as a sort of Time Machine in the cloud. It runs all the time and keeps everything on my machine backed up online. 3) I sync all my 1Password logins, etc. to my iPhone once a week. ...And that's it. I feel pretty covered. But I'm always reading stuff like this: http://www.43folders.com/2010/03/15/yes-another-backup-lecture And that doesn't even mention online backup, and seems like a huge pain in the behind. But maybe I'm being naive? Should I have more backups? Thanks for any feedback. I really appreciate it.

  • Software/hardware to build video streaming server?

    - by Sasha Yanovets
    I am looking for a video streaming server solution, something like online TV server, with ability to make live broadcasts in the internet. What software could you recommend for that? What kind of hardware it should run on, should be there anything special? I am looking for a solution that could be scaled up to at least 1000 simultaneous users online with good resolution of video. I think it is good to have general answer on what direction to choose. But here more details on my specific case: I just looking for a solution almost from scratch. We have some video content that we've produced, but it is not delivered over internet yet. We do not tied to any particular vendor for now. We want to make 24 hours of steaming three 8 hour blocks with change of content every day. We want the ability to make regular live broadcasts. I guess we will need to have several options of streaming quality (low ~56 kb/s mid ~273 kb/s). Some terms just foreign to me (like play-truncation rate), if you could point out what parameters we should avare of, it would be great. Uplink to the internet is to be determined. We plan to start from something and scale up on the way. If you are already have some kind of media streaming server, just describe its configuration here (hardware, OS, software), peak number of concurrent users it serves. I think it could help people approaching this task.

  • Capturing time intervals when somebody was online? How would you impement this feature?

    - by Kirzilla
    Hello, Our aim is to build timelines saying about periods of time when user was online. (It really doesn't matter what user we are talking about and where he was online) To get information about onliners we can call API method, someservice.com/api/?call=whoIsOnline whoIsOnline method will give us a list of users currently online. But there is no API method to get information about who IS NOT online. So, we should build our timelines using information we got from whoIsOnline. Of course there will be a measurement error (we can't track information in realtime). Let's suppose that we will call whoIsOnline method every 2 minutes (yes, we will run our script by cron every 2 minutes). For example, calling whoIsOnline at 08:00 will return Peter_id Michal_id Andy_id calling whoIsOnline at 08:02 will return Michael_id Andy_id George_id As you can see, Peter has gone offline, but we have new onliner - George. Available instruments are Db(MySQL) / text files / key-value storage (Redis/memcache); feel free to choose any of them (or even all of them). So, we have to get information like this George_id was online... 12 May: 08:02-08:30, 12:40-12:46, 20:14-22:36 11 May: 09:10-12:30, 21:45-23:00 10 May: was not online And now question... How would you store information to implement such timelines? How would you query/calculate information about periods of time when user was online? Additional information.. You cannot update information about offline users, only users who are "currently" online. Solution should be flexible: timeline information could be represented relating to any timezone. We should keep information only for last 7 days. Every user seen online is automatically getting his own identifier in our database. Uff.. it was really hard for me to write it because my English is pretty bad, but I hope my question will be clear for you. Thank you.

  • How to build a windows/web application that stores data locally and sync's with remote database?

    - by Jason
    Hello, I am needing to build an application that stores data locally and then synchronizes with a remote MS SQL database. I am not sure how to go about doing this. Enter data offline on a form and store the data. Synchronize the data with a remote MS SQL database when online. There will be many users who enter data offline, the local database on each pc needs to update when online and grab the 30 most recent records for use offline. Example: Each day users will enter data on their "form". The users will be offline. The users will return to the office and need to sync with the "online" database. The next morning the users will need to sync with the online database before going offline. They will need to have offline access to the 30 most recent records. (They will use the 30 records for charting/graphing while they are offline) I am very new to building apps. I have VS 2010. I am wondering where to start? What language to use? Is there a "framework" for doing this type of app? Any info or suggestions would be greatly appreciated. Thanks!

  • Can web apps allow fast data-typists to "type-ahead"?

    - by user61852
    In some data entry contexts, I've seen data typists, type really fast and know so well the app they use, and have a mechanic quality in their work so that they can "type ahead", ie continue typing and "tab-bing" and "enter-ing" faster than the display updates, so that in many occasions they are typing in the data for the next form before it draws itself. Then when this next entry form appears, their keystrokes fill the text boxes and they continue typing, selecting etc. In contexts like this, this speed is desirable, since this persons are really productive. I think this "type ahead of time" is only possible in desktop apps, but I may be wrong. My question is whether this way of handling the keyboard buffer (which in desktop apps require no extra programming) is achievable in web apps, or is this impossible because of the way web apps work, handle sessions, etc (network latency and the overhead of generating new web pages ) ? Edit: By "type ahead" I mean "keyboard type ahead" (typing faster than the next entry form can load), not suggets-as-you-type-like-google type ahead. Typeahead is a feature of computers and software (and some typewriters) that enables users to continue typing regardless of program or computer operation—the user may type in whatever speed he or she desires, and if the receiving software is busy at the time it will be called to handle this later. Often this means that keystrokes entered will not be displayed on the screen immediately. This programming technique for handling user what is known as a keyboard buffer.

  • SharePoint 2010 in the cloud a.k.a. SharePoint Online

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). There are 3 ways to run SharePoint On premises, you buy the servers, and you run the servers. Hosted servers, where you don’t run the servers, but you let a hosting company run dedicated servers. Multi-tenant, like SharePoint online – this is what I am talking about in this blog post. Also known as SaaS (Software as a Service). The advantages of a cloud solution are undeniable. Availability, (SharePoint line offers a 99.9% uptime SLA) Reliability. Cost. Due to economies of scale, and no need to hire specialized dedicated staff. Scalability. Security. Flexibility – grow or shrink as you need to. If you are seriously considering SharePoint 2010 in the cloud, there are some things you need to know about SharePoint online. What will work - OOTB Customization, collaboration features etc. will work SharePoint Designer 2010 is supported, so no code workflows will work Visual Studio sandbox solutions, client object model will work. What won’t work - SharePoint 2010 online cloud environment supports only sandbox solutions. BCS, business connectivity services is not supported in SharePoint online. What you can do however is to host your services in Azure, and call them using Silverlight. Custom timer jobs will not work. Long story short, get used to Sandbox solutions – and the new way of programming. Sandbox solutions are pretty damn good. Most of the complaints I have heard around sandbox solutions being too restrictive, are uninformed mechanisms of doing things mired in the ways of 2002. .. or you could just live in 2002 too.
