Hello, I have an Apache server running which hosts a php web application. Also, its provides provisions for downloading a file of size around 900MB from it. However, while testing the application I found out that its not possible to pause the downloads and resume them later on. Could someone help me? Is it an apache property I must change?

Advice needed: What tech expertise do I need to accomplish my goal?

- by quaternion

I have a business plan & money to hire a developer - the essentials involve simple online games for children (played via traditional computer over the internet) such that their scores are uploaded to a database that can be viewed via a nice portal. What I don't know is: what technologies I would want my developer to know (the only somewhat unusual requirement I have is that the games have relatively accurate timing of keypresses/mouse presses) how much I should expect to pay (in general, what is the appropriate range) how many hours a program of the complexity of a simple tower defense -type game should take to develop (to be clear, the idea is not to implement TD, but rather other games of similar complexity) whether I should go with capable acquaintances, some online kind of online web-dev bidding site, or just try to find a capable undergraduate at the local university who I can wow with his/her first big paycheck, how I should communicate the software's specifications to my hired developer... Is there a standard I should be using? whether I should hire a webdev consultant for a few hours to help me answer these questions, instead of asking stackoverflow Thanks for any advice!

Using Accelerometer in Wiimote for Physics Practicals

- by Omar

I have to develop some software in my school to utilize the accelerometer in the Wiimote for recording data from experiments, for example finding the acceleration and velocity of a moving object. I understand how the accelerometer values will be used but I am sort of stuck on the programming front. There is a set of things that I would like to do: Live streaming of data from the Wiimote via bluetooth Use the accelerometer values to find velocity and displacment via integration Plot a set of results Avoid the use of the infrared sensor on the Wiimote Please can anyone give me their thoughts on how to go about this. Also it would be great if people could direct me to existing projects that utizlise the wiimote. Also can someone suggest what would be the best programming language to use for this. My current bet is on using Visual basic. Any sort of help is greatly appretiated.

How to use a c# datagridview to update a database file just like Access does?

- by mackeyka

I have googled everywhere and I am finally giving up and asking here. I am working in Visual Studio 2010 with C#. I have set up a form with a datagridview connected to a MSSQL database and I need to save changes made in the datagridview back to the physical database. I am having some success but I think that I am going about some of it completely wrong because I can not get it to save consistently. What I really want is for the updates to work just like they do when working with Access. When I edit a row in the datagridview and then leave that row, either by selecting another row or by selecting some other control on the form or even by changing to another form or quitting the application the row should be automatically pdated to the physical database. The first part of this question I think is, what is the proper event to use to trigger the save and then second what methods should be used to actually write the data to the database?

Link all'interno di un campo testo

- by aleds

Ciao a tutti, nella Rails app che sto realizzando, l'utente ha la possibilita' di inserire un post (campo memo) con all'interno una URL. Ad esempio: "bla bla bla bla www.blabla.com bla bla bla ..." Nel mostrare tale post vorrei che www.blabla.com diventasse un link cliccabile (come avviene in twitter). Ovviamente deve essere fatto un parsing della url, immagino usando le espressioni regolari. Avete dei consigli in merito ? Esiste qualcosa di gia' fatto oppure inizio da subito a scrivere il codice :) ? Grazie Alessandro DS http://alex-on-rails.blogspot.com/

What is an example of a website/service which _isn't_ REST?

- by montooner

So I just started digging into web tech, and I'm stuck on the concept of REST. Could someone clarify REST by giving me an example of what isn't rest? So, as far as I can tell, REST requires the server and client to both be in the same state at the end of every request-response HTTP transfer. Does that sound right? My understanding is that, if a client stores state information locally (which the server does not know about), that service is NOT rest. Thanks in advance.

C: What is a good source to teach standard/basic code conventions to someone newly learning the language ?

- by shan23

I'm tutoring someone who can be described as a rank newcomer in C. Understandably, she does not know much about coding conventions generally practiced, and hence all her programs tend to use single letter vars, mismatched spacing/indentation and the like, making it very difficult to read/debug her endeavors. My question is, is there a link/set of guidelines and examples which she can use for adopting basic code conventions ? It should not be too arcane as to scare her off, yet inclusive enough to have the basics covered (so that no one woulc wince looking at the code). Any suggestions ?

Is there a way to install Ubuntu stripped down without desktop applications?

- by Nick Berardi

Just to start off, I know of lubuntu but it really doesn't meet what I am looking for. Basically what I am looking for is the standard Desktop Ubuntu install, but with out all the word processing, multimedia, and games installed. I have seen posts out about how to get the desktop environment running on Ubuntu server, but they seem complicated, and never seem to equal the standard Desktop install. So my question is, is there anyway to tell the standard Desktop install not to install all the applications? Or is there a distro available that leaves all the applications out, and just has the standard desktop look and feel? What I really want this for is, is for development purposes to run on a VM to do Mono development.

I am Final Year IT Engineering student. I am Doing Content Management System in ASP.net for my college.

Where can I define Conditional compilation constants for Delphi Prism?

- by Martijn

I've just ported a Web service from Delphi.NET 2006 to Delphi Prism 2009 (running in the Visual Studio 2008 IDE). But I can't find where I'm supposed to set (or unset) the conditional compilation constants! Am I blind, has this option been left out, or is it just not supported in VS? [edit: thanks to Mohammed Nasman for the link] MSDN tells me to set them using the Project Designer. First, it took me a while to figure out that the Project menu is only visible when the Solution is selected (and not the web service project). Then, there's still no way to set conditional compilation constants in the Project Designer! I just can't find a way to get to the Project Options in an ASP.NET project... Is it really not possible?

Is there a tool to navigate targets and properties 's definition?

- by Nam Gi VU

I'm working on a bundle of MSBuild script files and many many times I have the need of locating the definition of a called target or a property being used. At the moment, I have to search to the target/property 's name text and view the file containing that text - only then I can read the definition of the target/property I'm looking for. This remind me of the feature of class/variable navigation of Visual Studio: we can choose "Go to definition" or "Find references" when select a class name or a variable. Is there a similar way to work with MSBuild target/property/item? Hope to hear from all of you! Nam.

How to display my server's current response time to an average user

- by Jason

Sorry, I'm not really sure of the right way to ask this one so bear with me... We have a web application that runs on a set of servers at a data center (not in our offices) We want to be able to somehow 'advertise' to our clients/users that the availability or response time of our servers has met a standard throughout the day. I am being asked to come up with a standard metric that we can easily advertise on our login screen that shows current "standard response time" checked every x minutes. My thinking is that I need to capture something like the results of a traceroute from a server (either in our office, amazon, etc..) to one of the data center servers and come up with a Red/Yellow/Green type of a notifier for the login screen to let the user know that our tests are responding normally and if they are having delay issues it could be their network or connection to the internet. We have lots of clients in rural areas that have poor connectivity and we are trying to let them know any slowness might be on their end, not ours. I've got the LAMP stack to work with, but this could also be some other system all together as long as it can update the main server with the results. I already have pingdom reports that are available, but that's a bit more than people want to read sometimes. Any ideas on what I can do?

What is the ideal length of an URL slug

- by Sinan

To make pretty URL's from article titles I am using a simple function. However lately I an concerned about the ideal length of these "slugs". It is said that too many dashes are bad. However some article titles can be long and a too long URL may not be liked by google. Of course that defeats th whole idea of having URL slugs. So does anyone have any idea how long a URL slug should be. Should there be a limit on the "dash" charecters used?

Hi all, I am trying to a perform build automation on one of web application projects built using VS 2008. The _PublishedWebSites contains two folders: Web and Deploy.

.NET AxWebBrowser can't open page "Navigation to the webpage was canceled" error

- by Erdnod

Oh, I am stuck again on this quiet annoying problem. I am trying to do a little automated browsing using the axWebBrowser component and it worked before. Now all of a sudden I get the following message when I try to browse to a page. Navigation to the webpage was canceled What you can try: Refresh the page. I totally disabled my firewall, ran VS2008 in Administrator mode, I even installed IE8 all to no avail. By the way IE8 doesn't work either. I don't know if the problem is related but all I get when I put a URL into IE8 is this message. Internet Explorer cannot display the webpage I don't so much mind that, I just really need to get my visual studio axWebBrowser working.

Problem with connection to MS SQL Server database using SSMS

- by Charles

I have a database on line with Godaddy (who uses SQL Server 2005). They provide basic management tools, but tell you that for more advanced tools you can connect directly using SSMS. I followed their instructions to ensure my online database will accept remote connections, and can apparently log in using SSMS with success (after giving my hostname and access data). However: When attempting to expand the "Databases" folder tree, I get the following error: Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server& LinkId=20476 ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch.

What are the basic skills a beginner JavaScript programmer should have?

- by Sanford

In NYC, we are working on creating a collaborative community programming environment and trying to segment out software engineers into differing buckets. At present, we are trying to define: Beginners Intermediates Advanced Experts (and/or Masters) Similar to an apprenticeship, you would need to demonstrate specific skills to achieve different levels. Right now, we have identified beginner programming skills as: Object - method, attributes, inheritance Variable - math, string, array, boolean - all are objects Basic arithmetic functions - precedence of functions String manipulation Looping - flow control Conditionals - boolean algebra This is a first attempt, and it is a challenge since we know the natural tension between programming and software engineering. How would you create such a skills-based ranking for JavaScript in this manner? For example, what would be the beginner JavaScript skills that you would need to have to advance to the intermediate training? And so on.

Best toolkit for new Web application (odd requirements)

- by ireadit

I need to write a new application, and have no experience with any new technology, framework, or language. Here are the requirements: HTML front end (best if it's cross-browser friendly) Web deployable, but also ideally want to be able to install as standalone on a desktop SQL Server database Ideally, would like to use a good (and easy) AJAX toolkit with widgets Ideally, would like to be able to write in ASP.Net but later (or concurrently) also write in Java. This is a big concern, as I would like to not have to rewrite the whole thing. Is there a toolkit I can use that makes this cross-platform requirement easier? All suggestions and comments are much appreciated. Thank you.

Is it faster to do the pages first and CSS second, or should I do them at the same time?

- by Fred Haslam

I have been tasked with building a new web project from scratch, with the exception of reusing CSS files (the look and feel) from an existing project. In the past I have always completed development of the functionality and the web-ui before considering the appearance. This is mostly due to CSS development overlapping with the tail end of the project. I now have the opportunity to integrate a static set of CSS as I build the application. I have no experience with this circumstance. Would it be faster to develop the project and web-pages first, then integrate the CSS; or would it be faster to integrate the CSS as part of page development?
