  • How to set CSS style colors in GWT

    - by AmaltasCoder
    I have a GWT + AppEngine application that lets users create online polls. I want to let the poll creator choose from a variety of themes for his poll. We will save the theme a poll creator chose on the server and whenever a poll respondent access the poll he will get the questions with the chosen theme. A theme for us means a set of 4-5 colors which we will use to style the poll page. Our client side application is a GWT application with styles set inline in UiBinder templates elements, for example: <ui:style> .header { background: color1; padding: 6px 6px; } .anothercssclass { background: color2; padding: 6px 6px; } </ui:style> Please suggest how we can set the color1 and color2 from the theme saved on server. Please note this is NOT a GWT module theme question.

  • Python configuration file generator

    - by Stan
    I want to use Python to make a configuration file generator. My roughly idea is feeding input with template files and some XML files with the real settings. Then use the program to generate the real configuration files. I got several questions: Is there any open source configuration generator program? (what could be the keyword), I wonder if there's anything can be added/modified in the design. Does Python have good XML parser module? Is it good idea to use XML file to save the original settings? I've been thinking to use Excel since it's more intuitive to maintain, but harder for program to parse. Not sure how people deal with this. Hope the community can give me some suggestions. Thanks a lot!

  • Multiple Inheritance Debates II: according to Stroustrup

    - by asksuperuser
    I know very well about the traditional arguments about why Interface Inheritance is prefered to multiple inheritance, there has been already a post here : http://stackoverflow.com/questions/191691/should-c-include-multiple-inheritance But according to Stroustrup the real reason why Microsoft and Sun decided to get rid off multiple inheritance is that they have vested interest to do so: instead of putting features in the languages, they put in frameworks so that people then become tied to their platform instead of people having the same capability at a language standard level. What do you think ? Why Sun and Microsoft consider developers too immature to just make the choice themselves ?

  • Haskell: foldl' accumulator parameter

    - by Clinton
    I've been asking a few questions about strictness, but I think I've missed the mark before. Hopefully this is more precise. Lets say we have: n = 1000000 f z = foldl' (\(x1, x2) y -> (x1 + y, y - x2)) z [1..n] Without changing f, what should I set z = ... So that f z does not overflow the stack? (i.e. runs in constant space regardless of the size of n) Its okay if the answer requires GHC extensions. My first thought is to define: g (a1, a2) = (!a1, !a2) and then z = g (0, 0) But I don't think g is valid Haskell.

  • Process for Upgrading from RedBean 3.5 to RedBean 4

    - by Jay Haase
    I am currently using RedBean version 3.5. I think I would like to move to the latest version of RedBean, version 4. I have found no documentation about upgrade process and have a number of significant questions: Is my RedBean 3.5 database schema compatible 4, or will up have to migrate all of the tables to some new format? Is any of my RedBean 3.5 code compatible with version 4, or wouldI need to rewrite all of my code that uses RedBean 3.5? Would it make more sense to upgrade to Doctrine? As a side note, I am also feeling concerned about RedBean's drop of support for Composer, which I have found to be über helpful in managing the various versions of libraries I am using.

  • How to perform dynamic formatting with perl during write?

    - by Bee
    I have a format which is defined like below: format STDOUT = ------------------------------------ |Field1 | Field2 | Field3 | ------------------------------------ |@<<<<<<<<<<| @<<<<<<<<<<<| @<<<<< |~~ shift(@list1),shift(@list2),shift(@list3) ------------------------------------ . write STDOUT; So the questions are as below: Is it possible to make the list of values printed dynamic? e.g. If list 1 contains 12 elements, and if $flag1 is defined, then print only elements 0..10 instead of all 12. I tried doing this by passing $flag as a parameter to the sub which generates the report. However, the last defined FORMAT seems to always take precedence and the final write when it happens, applies the last format no matter what the condition is. Is it possible to also add/hide fields using the same process. e.g. If $flag2 is defined, then add an additional field Field4 to the list?

    - by sunwukung

    - by Pranz
    Hello everyone, I am making a Google Analytics like project for my school assignment. I have two questions primarily: 1) Exactly when does Google store the data to the database? When it does it use XHR with some server side scripting language to store it to the database or is there a way to do it using plain javascript? 2) How do I get the IP address of a user from Javascript? How does Google do for Analytics?? Thanks for all the help. Pranz

  • To use an api or store a large dataset in a rails app?

    - by Dave
    Hi all- I am working on a site that has the potential to need a LOT of space. Basically we hope to have every video game every created stored in a database along with an image of the cover. There are some api's out there that might be able to help, like GiantBomb's (www.giantbomb.com). We are trying to decide whether to store the data locally and if so where to find that comprehensive a list, or make calls to the api on demand. The problem with the latter is likely latency and also downtime problems. Assuming we want to store it locally here are the questions: 1) Where can we find this kind of data (yes, I looked on google, and no I couldnt find anything:)) 2) What is the most efficient way to encode and store the images? Thanks!

  • I want to make my own Malloc

    - by Unknown
    I want to make my own malloc/free so I can make a precise copying allocator. Any gurus have any tips and suggestions? I have a few questions for now: Should I just malloc large chunks of memory, and then distribute from that so I don't have to call the system calls? How are copying collectors usually done? I would imagine that this part is a bit complicated to do efficiently. My naive implementation would just malloc a block the size of the remaining objects which would require 2x the space.

  • Is this plain stupid: GIT Sharing Via DropBox?

    - by yar
    I realize that there are similar questions, but my question is slightly different. I'm wondering whether sharing a bare repository via a synchronized DropBox folder on multiple computers would work for sharing code via GIT. Really what I want to know is: is sharing a GIT repo via DropBox (the repo gets updated on each person's local drive) the same as sharing it from one centralized location, e.g., via SSH, git or HTTP? Is this the same or different from sharing a GIT repo via a shared network drive? Note: This is not an empirical question: it seems to work fine. I'm asking whether the way a GIT repo is structured is compatible with this way of sharing. EDIT To clarify/repeat, I'm talking about keeping the GIT repository on DropBox as a bare repository. I'm not talking about keeping the actual files that are under source control in DropBox.

  • (Secure) alternative to TLS / SSLv3 ?

    - by CSkau
    Toying with an idea for a F2F networked application I've just been reading up on secure communication. I quickly settled with the idea of using TLS / SSL as the basis for any communication since it employs Public Key encryption at the protocol level and thus is perfect for my needs. However I was surprised to read (on wikipedia) that the newest version of TLS, SSLv3 uses a mix of MD5 and SHA-1 "because if any vulnerability was found in one of these algorithms the other would prevent it from compromising SSLv3". However, as I take it, lately both have been found flawed ! So my questions are thus: Does this not mean that SSLv3 is basically flawed, or am I not reading close enough ? And if so does a "secure" alternative to SSLv3 exist ?

  • Trying to call JS Code that is passed back from AJAX call....

    - by Dutchie432
    Okay, so I have an javascript function that retrieves some HTML... function updateQuestions(i){ var url = 'getQuestions.php?sys=' + i; if (receiveReq.readyState == 4 || receiveReq.readyState == 0) { receiveReq.open("GET", url, true); receiveReq.onreadystatechange = handleQuestionsUpdate; receiveReq.send(null); } } function handleQuestionsUpdate() { if (receiveReq.readyState == 4) { var a=receiveReq.responseText; document.getElementById('questions').innerHTML=a; checkSpeakers(); //Error Occurs Here, even though checkSpeakers() is a function in the returned HTML chunk. } } This HTML is not just HTML, but it is more specifically a form and a chunk of javascript. The javascript is hard-coded into the HTML and not referenced by <script src=".."> Is it normal that this retrieved JS code isn't recognized upon call-time? If so, what is my alternative if I need the JS to change every time the div is update? Now

  • Histrogram matching - image processing - c/c++

    - by Raj
    Hello I have two histograms. int Hist1[10] = {1,4,3,5,2,5,4,6,3,2}; int Hist1[10] = {1,4,3,15,12,15,4,6,3,2}; Hist1's distribution is of type multi-modal; Hist2's distribution is of type uni-modal with single prominent peak. My questions are Is there any way that i could determine the type of distribution programmatically? How to quantify whether these two histograms are similar/dissimilar? Thanks

  • More Poll() ?'s

    - by ultifinitus
    Back again! I've been doing some async socket programming with select() on windows,and it's been working quite well. However it's only scalable up to 1024 clients.Poll() is the way to get around that limitation, and I know it works on both linux and unix. But it doesn't work with a windows system correct? I read about WsaPoll(), does it have the exact same functionality? What libraries would I have to link to in order to use it? Can I increase the socket number safely in windows with FD_SETSIZE? My end program will be on a linux server. However I am testing on a windows system right now. Should I just swap my test machine over to a linux box? (probably going to anyway) Otherwise what would you recommend to use with windows? (sorry for all of the questions, I am doing research on my own, I promise =D)

  • Python: get windows OS version and architecture

    - by Thorfin
    First of all, I don't think this question is a duplicate of http://stackoverflow.com/questions/2208828/detect-64bit-os-windows-in-python because imho it has not been thoroughly answered. The only approaching answer is: Use sys.getwindowsversion() or the existence of PROGRAMFILES(X86) (if 'PROGRAMFILES(X86)' in os.environ) But: Can we completely rely on the windows environment variable PROGRAMFILES(X86)? I fear that anyone can create it, even if it's not present on the system. How can we use sys.getwindowsversion() to get the architecture? Regarding sys.getwindowsversion(): The link http://docs.python.org/library/sys.html#sys.getwindowsversion leads us to http://msdn.microsoft.com/en-us/library/ms724451%28VS.85%29.aspx but I don't see anything related to the architecture (32bit/64bit). Moreover, the platform element if the returned tuple seems to be independent of the architecture. One last note, I'm using python 2.5. Thanks!

  • Exporting MS SQL Schema and Data

    - by stringo0
    I'm used to MySQL and PHPMyAdmin - I had to switch over to MSSQL for an ASP.net project, and I'm having tons of trouble. I'm using the express version of SQL 2008, with SQL Server Management Studio. The following are 2 questions I've been struggling with for a while: 1) How do I export the DB schema for the database? The table structure, etc.? 2) How do I export all the data in the database? Ideally I'd like to have a .sql file that can be run wherever I need the schema or data duplicated, for example a co-worker's computer for a shared project, or online when the project is being hosted. Thanks!

  • glTexParameter and filtering in OpenGL and GLSL?

    - by sharoz
    I have a couple questions about glTexParameter and filtering 1) What is the scope when applying a glTexParameter (specifically the filtering)? Here's a scenario: Bind a texture. Set the filters to LINEAR Set the texture to "Sampler1" of a shader Bind another texture. Set its filters to NEAREST Set that texture to "Sampler2" of a shader Draw When I use the textures in a shader, will one be linear and the other be nearest? Or will they both be nearest because it was called last? 2) Is it possible to set the filtering method in GLSL? Thanks in advance!

  • visual studio C++ toggle comment ? comment while not whole line is selected ?

    - by Mr_and_Mrs_D
    2 questions actually : 1) shortcut to toggle comment on selected lines ? Available on all iDEs I used starting with notepad++ 2)the ctrl-k, ctrl-c exhibits this behavior (quoted from someplace nicely worded): C#: Each line where some text is selected is commented at the line-start with double-slash. If nothing is selected, the line where the cursor is is commented. C++: If nothing is selected or complete lines are selected, it behaves as above. However, if parts of a line are selected, and no comment is selected as part of the selection (ex. select something in the middle of a code line), then the selection is surrounded by /* and */. since I code in C++ I find this behavior annoying - I want to be able to comment out lines partially selected - any workarounds ?

  • Need guidance for my first Android application: how many activities should I use?

    - by jul
    Hi, I'm starting Android doing an application for searching restaurants, and some guidance would be welcome! On the first screen I'd like to have a search field with a submit button (I get the data from a web service), and below a list with the results of the search. When clicking on one of the items of the list it will show a screen with the restaurant details as well as a map showing its location. My questions are: Can I do everything in one single activity or should I do an activity for the search, one for the result list, one for the restaurant description, and another for the map? Would doing one single activity make the application more responsive? How can I use a list and a map within a normal activity (without ListActivity and MapActivity)? Any help, pointer, example application or sample code is very appreciated! Thank you Jul

  • How Can I Determine if HTTP Requests/Responses are compressed in IE7?

    - by DTS
    I'm trying to use Fiddler (v2.2.2.0) to see if HTTP traffic through IE7 is being compressed. I'm not seeing Accept-Encoding or Content-Encoding request/response headers being sent/returned and I do not need to decode the response data once it's arrived, which leads me to believe that the responses are NOT coming back compressed. However, when making the same requests using FireFox 3.5.7, I could see through FireBug that FF was sending Accept-Encoding and YSlow at least thought my data was coming back compressed. A comment in this question: http://stackoverflow.com/questions/897989/using-fiddler-to-check-iis-compression suggested that a proxy server may be to blame for stripping out headers and decompressing the content for security reasons. I am using Verizon FIOS for my broadband at home and am now wondering if Verizon is proxying my HTTP traffic? In short, how can I positively confirm/deny that responses are coming back compressed through IE? Thanks.

  • SharePoint use for web application

    - by Adam
    Hi - we are looking at developing a web application that allows users (some subscribed (authenticated) and some not (browsing)). We would like some basic document management, a wiki, a blog etc. and do not expect the app to be heavily used (DB size not an issue at this stage). I require the GUI to be customised to our corporate style and we access to .net development skills which we would like to leverage to develop the application. With this in mind I have the follwoing 3 questions: Is WSS 3.0 / SPF 2010 the correct framework to be building this app on? What are the licensing terms or are these frameworks similar to the .Net framework that once installed on our host server we can use the base services provided to develop our apps on? I hope this makes sense & thanks in advance for any responses.
