• SaaS practical basics and projects

  - by Medardas

  So i need some directions. I want to understand Cloud Software as a Service(SaaS) practical initialization. The thing is I want to create a simple cloud service which would let me run programs on this cloud from remote machine. As I understand, I need some kind of specific backbone project to start this system, similar like OpenStack or Apache Cloud for Infostructure as a Service. Of course it may be that I understand it completely wrong and even if there is such project, it is not open source, free. I could also comprehend SaaS building on IaaS, but the thing is, I can't find any practical information at all. Could Somebody indulge me if there is any kind of free licence SaaS project or recommend a related articles or explain everything in a nut case with atleast vague direction.

• How do I upload a file from a Java servlet to a location on a web server within Tomcat/webapps

  - by Ankur

  How do I upload a file from a Java servlet to a location on a web server within Tomcat/webapps. I am using Commons upload. I have a location such as myserver:8080/myapp/mylocation where I want to put the files that are uploaded. I tried using getServletContext().getRealPath("/"); to find where I am and then appended that with mylocation but I get a nullpointer exception. I know I sound vague, it's because I am confused about the big picture, what are the generals steps I need to perform to make this work. Any code or links to code would be much appreciated.

• Trying to get simple jquery animations on a site I created in Dreamweaver

  - by JoeOzz

  Hey guys, another question. I'm trying to do some basic jQuery stuff for my final project. I'll be using it to modify my already existing site created in Dreamweaver a few months ago. However, no matter how I source the framework, it just won't take regardless of whether I host my own copy or link to someone else's like Google's. I'm including my jQuery function calls within my already existing .js file that includes some auto generated functions. I also tried creating a new .js specifically for my jQuery functions and still nothing. I realize this is vague, but any tips? Do I need another framework for jQuery to work off of to make animations like .fadeIn() or .slideDown()? Thanks guys and gals!

• Is there a name for the technique of using base-2 numbers to encode a list of unique options?

  - by Lunatik

  Apologies for the rather vague nature of this question, I've never been taught programming and Google is rather useless to a self-help guy like me in this case as the key words are pretty ambiguous. I am writing a couple of functions that encode and decode a list of options into a Long so they can easily be passed around the application, you know this kind of thing: 1 - Apple 2 - Orange 4 - Banana 8 - Plum etc. In this case the number 11 would represent Apple, Orange & Plum. I've got it working but I see this used all the time so assume there is a common name for the technique, and no doubt all sorts of best practice and clever algorithms that are at the moment just out of my reach.

• HTML: How to get a child element to show behind (lower z-index) than its parent

  - by dclowd9901

  I need for a certain dynamic element to always appear on top of another element, no matter what order in the DOM tree they are. Is this possible? I've tried z-index (with position: relative), and it doesn't seem to work. I hate to be vague, but this is the simplest way I can think of asking this question without explaining its purpose ad nauseum. So, to recap, I need <div class="a"> <div class="b"></div> </div> <div class="b"> <div class="a"></div> </div> To display exactly the same when rendered. And for flexibility purposes (I'm planning on distributing a plugin that needs this functionality), I'd really like to not have to resort to absolute or fixed positioning.

• XML::XML2JSON "0" Element

  - by Kevin C

  I'm using XML::XML2JSON in Perl to convert JSON data to XML, I am passing through the following data (snippet): {"question":{"isrequired":{"$t":"0"}}} and when I use the XML:XML2JSON-json2xml function to convert the JSON data into XML, I get the following (snippet): <isrequired/> I need to retain the "0" element in the "isrequired" tag, because at times, I will have empty JSON elements, and need the empty XML tag. I think the documentation is a bit vague (either that, or I don't understand it), but is this possible to do with this module? I would appreciate the help. Thanks.

• Google Maps API v3... non-mobile?

  - by andrhamm

  I'm trying to make a Google Maps widget for my website but all of the examples are for full-screen mobile devices. The tutorials work when I copy paste them exactly as shown but they don't seem to work when I want them to only occupy a portion of the page. From what I've read, the v3 is the best API yet (for what I need) because of its speed and compatibility with mobile devices. I plan to make a widget very similar to the MarkerClusterer example from the demo gallery but I can't get it working. Is this a common issue? I know I'm being vague but I would appreciate some help. Thanks

• I DISTINCTly hate MySQL (help building a query)

  - by Alex Mcp

  This is staight forward I believe: I have a table with 30,000 rows. When I SELECT DISTINCT 'location' FROM myTable it returns 21,000 rows, about what I'd expect, but it only returns that one column. What I want is to move those to a new table, but the whole row for each match. My best guess is something like SELECT * from (SELECT DISTINCT 'location' FROM myTable) or something like that, but it says I have a vague syntax error. Is there a good way to grab the rest of each DISTINCT row and move it to a new table all in one go?

• Is it safe to catch EXCEPTION_GUARD_PAGE

  - by Michael J

  Environment is VC++ 9 on various Win platforms (XP and later) I'm writing an unhandled exception handler. I have a vague recollection from my kernel days that it was bad to catch an EXCEPTION_GUARD_PAGE, as this was generated to tell the OS to enlarge the stack. My question is twofold: Can such an exception occur in user space? If so, is it safe to catch it? I'm not especially interested in doing anything with it. I just want to know if I need to put special code in to not catch it (as I'm catching everything at the moment).

• MCV/MVP Patterns and Applications that interface with Hardware (DAQ/PLC/etc)

  - by Ryan

  I've been reading a lot about the MCV and MVP patterns for use with UI and it seems like a really nice powerful way to handle user interfaces. I am - however - having a difficult time deciding how this could integrate into a system where data in the model is created from a Data Acquisition System or Serial/Ethernet devices. There is also the added step that 70% of application interaction is performed by a PLC instead of a live user. It seems that for apps that just read/write & manipulate information from a database this works great, but how does does hardware and automation fit into these patterns? Is it as simple as another controller (for lack of a better term) that interacts with hardware that manipulates data and writes to a model? Maybe I am over thinking this or thinking too simply, so any advice would be great. I'm not quite sure where I'm going with this, so if something doesn't make sense or I was too vague leave me a comment. Thanks!

• Asp.net error object not set to a reference

  - by Frank

  Hi all, Because I rush in development (a lot of whip cracking here) and declare my objects at the top of the function and instantiate inside my try-catch block, I get a lot of the good old "object not set to an instance of an object" errors while doing TDD, and later if I do miss a branch that object was used in (doing VB now, would prefer C#) or just in every day coding, object not set to an instance of an object is a bit vague. Sure the stack trace sends me to the line the error occured at, but it would be nice if I could modify my logging to either name the object or its type because sometimes I have multiple objects on the same line. It's not the end of the world, but in the end it would save me a few minutes each day. Any ideas on how I can pass the info on which object wasn't set? Thanks

• SharePoint WSS 3.0 - Fastest approach to build data-bound forms?

  - by Rusty Scupper

  Pardon the vague question, but I've just inherited a project to build a couple dozen forms pulling data from a SQL 2005 database. The forms are mostly standard database lookups with just a couple updates so the data layer is very simple -- I'm the DBA -- but we just recently started using SharePoint WSS 3.0 for a departmental web site and I would prefer to integrate these forms into WSS rather than build a separate standalone ASP.NET app. I'm hoping there is some RAD framework out there that integrates with WSS for data bound forms. I've been searching online, but haven't found anything very promising and the data viewer web part in SharePoint Designer looks complicated to integrate with an external SQL database. TIA, Rusty

• MySQL query for initial filling of order column

  - by Sejanus

  Sorry for vague question title. I've got a table containing huge list of, say, products, belonging to different categories. There's a foreign key column indicating which category that particular product belongs to. I.e. in "bananas" row category might be 3 which indicates "fruits". Now I added additional column "order" which is for display order within that particular category. I need to do initial ordering. Since the list is big, I dont wanna change every row by hand. Is it possible to do with one or two queries? I dont care what initial order is as long as it starts with 1 and goes up. I cant do something like SET order = id because id counts from 1 up regardless of product category and order must start anew from 1 up for every different category.

• Determining idle network transfer bandwidth

  - by rwmnau

  I'm building an application that will move around some potentially large files, but I want to do it without disturbing the user's network connection by flooding it. I know that Windows BITS has this kind of functionality, and that's essentially what I'm looking to replicate (as far as the throttling goes). I know BITS has other functionality as well that I'm not interested in, and I also have the option to consume it from .NET, but I'm interested in how it works. I've looked online, and I haven't found a clear explanation of how exactly BITS determines how much bandwidth to consume, aside from a vague "BITS polls activity to watch for a drop in the bandwidth used by other programs." What does this mean? Bandwidth consumed by other programs can drop for a number of other reasons as well - can BITS tell the difference? If I was looking for a process that replicated this "stay just under the radar, where the user won't notice the transfers" functionality, how would I go about doing it?

• If don't own proprietary database engine, what is best way to convert database to mysql?

  - by John Robertson

  I work for a very small company. I was recently faced with the question of whether there is a good way to convert a proprietary database to a MySQL database without owning the proprietary database engine e.g. if one is given a large oracle database file (or choose your favorite proprietary database engine format), but doesn't have a license for the oracle database engine, is there a good, perfectly reliable way to convert it to a MySQL database format that can be read with the MySQL database engine? My question is very vague as to which proprietary format is the source just because there would be multiple sources and it looks like they would be "various and sundry". My suspicion is that there is no perfectly reliable way, especially for a wide variety of proprietary databases. If there are a few proprietary formats for which this is possible, I would still be interested in knowing, though "various and sundry" is probably the real issue. Minimizing cost, effort and correct conversion are key so I think this is probably is the not possible list. -John

• Custom components vs default components in GUI Design. Which is more practical? (.NET)

  - by AlexRednic

  Ok, so is it better to create my own components (Either inherit them from existing ones or creating them from scratch) or to use the ones that come by default? I'm asking this under the umbrella of scalability, overhead and other factors that my contribute on each of the choices. UPDATE: Sorry if I'm to vague. I don't really know how to explain myself better. Isn't it a good idea to inherit each default component? For example what if I'm to design a rather large application and for example i need to change the display format on a DateTimePicker. Wouldn't it better to think ahead and inherit it and use the inherited component instead of the defaults? But, wouldn't it add a lot of overhead in small applications?

• Running sites on "localhost" is extremeley slow.

  - by seanxe

  Hello all, Having real trouble using my local host to test sites. It runs extremely slow! Sometimes up to a minute to load a page. I'm using firefox and the sites i'm testing run fine on other developers in my office local machines/ on the production server. I've gone through the normal things :- Disabled IPv6 Not running in debug mood Put the site in the highest app pool (High Isolated) on IIS 6. Taking of firewalls etc. The problem only seems to occur when hitting pages which contain some form of .net code in the code-behind. Appreciate that this a little bit of a vague topic / stab in the dark but would appreciate any sort of advice - it's horrible waiting a minute each refresh to try out a change! Cheers, Sean.

• analyzing hashes

  - by calccrypto

  Is anyone willing to devote some time to helping me analyze a (hopefully cryptographically secure) hash? I honestly have no idea what im doing, so i need someone to show me how to, to teach me. almost all of the stuff ive found online have been really long, tedious, and vague the code is in python because for some reason i dont know c/c++. all i know about the hash: 1. there are no collisions (so far) and 2. differences between two similar inputs results in wildly different differences and please dont tell me that if i dont know what im doing, i shouldnt be doing it.

• POST from a submit button in C#

  - by Marlon

  I'm not familiar with http stuff, but how would I be able to submit data to a website? There is a submit button that I would like to "press" from a console app. This is not my own website. This is part of the page source, not sure if it has any relevance: <form action="rate.php" method="post"> I looked at the HttpWebRequest class but I am unfamiliar with what properties I need to fill in. Sorry I'm so vague but I'm not familiar with http.

• What would you like to see in a book about Rails 3?

  - by Ryan Bigg

  Hello, I'm thinking of writing a book about Rails 3 and I have a basic idea of what I want to write about, but really what I need is that little bit of polish from the community. The book is planned to cover: A little bit of Ruby Version control using Git Testing using RSpec & Cucumber Life without Rails (Rack) Developing an application in Rails (vague, I know, sorry! Work in progress) Javascript testing using Selenium Background processing Document databases (a tentative maybe, at this stage) Monitoring an application And a little more. So, I leave this question for you: What do you want to see in a book about Rails 3, which goes from "This is Rails" to "This is how Rails scales"?

• What is a practical use for a closure in JavaScript?

  - by alex

  I'm trying my hardest to wrap my head around JavaScript's closures. I get that by returning an inner function, it will have access to any variable defined in it's immediate parent. Where would this be useful to me? Perhaps I haven't quite got my head around it yet. Most of the examples I have seen online don't provide any real world code, just vague examples. Can someone show me a real world use of a closure? Is this one, for example? var warnUser = function (msg) { var calledCount = 0; return function() { calledCount++; alert(msg + '\nYou have been warned ' + calledCount + ' times.'); }; }; var warnForTamper = warnUser('You can not tamper with our HTML.'); warnForTamper(); warnForTamper(); Thanks

• find a duplicate entry in an array in constant space and O(n) time [closed]

  - by Anubhav Agarwal

  Possible Duplicate: Algorithm to find a duplicate entry in constant space and O(n) time Given an array of N integer such that only one integer is repeated. Find the repeated integer in O(n) time and constant space. There is no range for the value of integers or the value of N For example given an array of 6 integers as 23 45 67 87 23 47. The answer is 23 (I hope this covers ambiguous and vague part) I searched on the net but was unable to find any such question in which range of integers was not fixed. Also here is an example that answers a similar question to mine but here he created a hash table with the highest integer value in C++.But the cpp does not allow such to create an array with 2^64 element(on a 64-bit computer).

• SSIS Script Component, Allow Null values

  - by user2471943

  I have a SSIS package that I am programming and my script component won't allow null column inputs. I have checked the box to keep nulls in the flat file source component. My program is running well until my script component where I get the error "The column has a null value" (super vague, I know). The column currently throwing the error is an "int" valued column and is used for aggregations in my script. I could make the null values 0s or to say "NULL" but I'd prefer to just leave them blank. Any advice on how to handle this problem would be greatly appreciated! Thanks in advance! I am using SQL Server BIDS 2008.
