• Tips/Process for web-development using Django in a small team

  - by Mridang Agarwalla

  We're developing a web app uing Django and we're a small team of 3-4 programmers — some doing the UI stuff and some doing the Backend stuff. I'd love some tips and suggestions from the people here. This is out current setup: We're using Git as as our SCM tool and following this branching model. We're following the PEP8 for your style guide. Agile is our software development methodology and we're using Jira for that. We're using the Confluence plugin for Jira for documentation and I'm going to be writing a script that also dumps the PyDocs into Confluence. We're using virtualenv for sandboxing We're using zc.buildout for building This is whatever I can think of off the top of my head. Any other suggestions/tips would be welcome. I feel that we have a pretty good set up but I'm also confident that we could do more. Thanks.

• Update/Insert With ADF Web Service Data Control

  - by shay.shmeltzer

  The Web service data control (WSDC) in ADF is a powerful feature that allows you to easily build a UI on top of WS interfaces exposed by other systems. However when you drag a WSDC to a page you usually get a set of output components where the data is shown. So how would you actually do an update operation on those values? The answer is that you need a call to another method in your WSDC that does the update - but what if you want to pass to it the actual values that you get from the get method you invoked before? Here is a demo showing how to do that: The two tricks that are shown here are: Changing the properties of items in the DC to be updateable - this gives you inputText fields instead of outputText fields. And passing the currentRow.dataProvider to the update method (and choosing the right iterator for this).

• Web Site Development Software for VirtualBox Ubuntu 11.04

  - by Paul Sonier

  I'm doing some development of a website on a VirtualBox guest running Ubuntu 11.04 (host is running Windows, but I want to do the web development in a Linux environment). My development languages are primarily PHP and Javascript (using Apache and node.js). The question is this: is there a good IDE for work under these conditions that can handle running virtualized? I tried Eclipse, and was not particularly thrilled with the performance; I'm wondering if there's some other way to do this than to do all my text editing in emacs.

• Web application framework for embedded systems?

  - by datenwolf

  I'm currently developing the software for a measurement and control system. In addition to the usual SCPI interface I'd also give it a nice HTTP frontend. Now I don't want to reinvent the wheel all over again. I already have a simple HTTPD running, but I don't want to implement all the other stuff. So what I'm looking for is a web application toolkit targeted at embedded system development. In particular this has to run on a ARM Cortex-M4, and I have some 8k of RAM available for this. It must be written in C. Is there such a thing or do I have to implement this myself?

• Where can I get a cheap database, no web hosting needed

  - by PhilipK

  I'm building an application which requires a fairly small online MySQL database. I don't need any web hosting. What are some cheap options for an online database? *Edit(a bit more about what I'll be using it for) The database itself is very small it contains market statistics for 5 weeks of time. Once a week the data will be updated, so that it always contains the most recent 5 weeks. Then I will use the data in that to create an XML file which is generated with PHP. The XML file will need to be accessed hundreds-thousands of times per month.*

• Is there a best practice / standard approach to a free trial for a web app

  - by wobbily_col

  I have an idea for a web app, and would be interested in implementing it, and offering a free trial of say 5 uses before asking people to sign up. I can think of numerous ways of doing this (using cookies , logging IP adresses off the top of my head, limiting functionality). Is there a standard approach to this? Are there best practices? Are there any good tutorials on this? (I would prefer not to go the liited functionality route, as it will not show what the app is capable of).

• Gracefully terminate a request based service on server

  - by Jatin

  In our web application, for each http-request there is a lot of computation that happens on back end. Output can vary from 10 sec - 1 Hour. In the mean time when it is computed, "Waiting.." is shown on the website for the respective user. But it so happens, that a user might cut down the service in between. So what all can be done on the back end so that the computation can be stopped in between to save resources? What different tactics can be applied here? And if better (instead of killing the thread directly), then a graceful termination policy should make wonders.

• Architecture guidelines for a "single page web-app"

  - by Matt Roberts

  I'm going to start a side project to build a "single page" web application. The application needs to be real-time, sending updates to the clients as changes happen. Are there any good resources for best-practice approaches wrt the architecture for these kinds of applications. The best resource I've found so far is the trello architecture article here: http://blog.fogcreek.com/the-trello-tech-stack/ To me, this architecture, although very sexy, is probably over-engineered for my specific needs - although I do have similar requirements. I'm wondering if I need to bother with a sub/pub at the server side, could I not just push updates from the server when something happens (e.g. when the client sends an update to the server, write the update to the db, and then send an update to the clients). Tech-wise, I'm probably looking to build this out in Node.JS or maybe Ruby, although the architecture guidelines should to some extent apply to any underlying server technologies.

• Chrome Web Store verification

  - by Vince V.

  A couple of days ago I created an extension for Chrome and added it to the store. Now I want it to get verified. I payed the 5 dollar and added my website to Webmaster Tools. The website is also verified on those Webmaster Tools. Today I wanted to add my URL to my extension (ultimately to do online installations) but it doesn't recognize the URL I put in those Webmaster Tools. I tried refreshing and clicking add site, but it just doesn't work. Is there some step that I am missing or is this a bug in the Chrome Web Store, because I don't see any option left.

• Why are most websites optimized for viewing in portrait mode?

  - by NVM

  I simply cannot figure this out. Almost all monitors have an aspect ratio where width is much bigger than the height and yet almost all websites are designed exactly for the other way round? I am not really a web developer and am just experimenting stuff at the moment but this madness baffles me!!! Edit: The point is not that I would like to limit the height of a website. The point is that I'd wat it to somehow fill all available space when I have my 1920x1080 in landscape mode. Edit 2: See this to understand what I am saying

• How to remove google ads virus from IE?

  - by msbg

  I have picked up adware in that shows extra irrelevant google ads. This only happens in Internet Explorer 10, not Firefox or Iron. I have tried some removals for similar viruses with no luck. I have scanned with MalwareBytes, Windows Defender(I am using Windows 8 RTM, so this is the same as MSE), Spybot, Ad Aware, McAfee, Norton, and AVG, with no luck. Here's a screenshot: As you can see, ads are added to the tan area as well as several extra white results, which are especially irrelevant. I like IE10 and would like to keep using it, but these ads are annoying. I'm also worried there may be spyware as well.

• Google Loon–A network of balloons to provide internet to everyone

  - by Gopinath

  Google once just a super powerful search engine provider and now they are venturing in to a lot of interesting non software projects like self driving cars, glasses that beam information right on to your eye balls, high speed internet services @ 1 Giga bytes per second. A recent addition to this innovative list is Google Loon – a network of flying balloons that provide internet access to remote parts of the world where it is not feasible for many governments/corporate to provider internet services. Google says there are several billions of people around the world who don’t have access to internet and Google Loon aim is to provide internet facilities to all these people. A pilot project is started couple of days ago by launching 30 balloons into stratosphere from New Zealand. These balloons fly 20 Kilometers above earth(much higher than where aero planes fly) and they beam internet to homes having Loon receiver wirelessly. Checkout the embedded introductory video on Google Loon What is in it for Google? Why is Google getting into these type of projects and what is in it for them? Google is the gateway to web and majority of people find information on web using Google Services/Software. So providing internet facilities to more people means, more people using Google services and it in turn contributes to their revenue growth. Google is not a charity, they do all these projects to earn money just like every other corporate. The best part is while earning money they are touching lives of billions of people in a positive way. Just imagine everyone in the world connected and have ability to take informed decisions irrespective of whether they live in developed countries or underprivileged parts of the world! Wow that will be a beautiful day.

• Why maximum 1.0 Gbit Ethernet connection an old notebook, and only 100 Mbit on newer faster computer

  - by Sam

  Strange problem about Ethernet speed: recently we bought an i7 core computer running Win7 64 bit with an onboard Gigabit Ethernet controller (Realtek PCIe Gbit Ethernet Family controller). Connecting this new fast pc directly to our brand new ASUS Gigabit Ethernet router via CAT6 cable(!) shows up the adapter status (see picture attached) only 100mbit, while the router is capable of 1000 mbit. More facts: Connecting an 8 year old IBM notebook with gigabit ethernet to the same cable end shows 1.0 Gbit connection in its adapter status. Speedtest.net shows 35 mbit/s down on the new computer Speedtest.net shows 78 mbit/s down on the old rusty IBM notebook. We have an 120 mbit down internet connection, which we we truly receive on another pc (also directly connected to the router) How to get the 1.0 Gbit going in the new pc ?

• Open Source Web-based CMS for writing and managing API documentation

  - by netcoder

  This is a question that have somewhat been asked before (i.e.: How to manage an open source project's documentation). However, my question is a little different because: We're not developing open source software, but proprietary software The documentation has to be hand-written, because we do not want to publish the actual software API documentation, but only the public API documentation I do want developers and project managers to write the documentation collaboratively Obviously, wikis are a solution, but they're very generic. I'm looking for a more specialized tool for this job. I've looked around and found a few like Adobe Robohelp, SaaS solutions and such, but I'd like to know if any open source software exists for that purpose. Do you know any Open Source Web-based CMS for writing and managing API and software documentation?

• Collaboration between client, web designer, and web developer

  - by Alex

  I am primarily a Web Developer (back end programming) - but intend to offer a complete service to my clients, from concept, to brand design, photoshop mock-ups and everything else in between. I'm aware that it's a good idea to outsource this design aspect of the project to someone that I trust. My question is more about the process: I imagine that in order for the designer to really grasp what the client wants to create, they would need some sort of interaction. Therefore, does anyone know if it is common to bring both parties into a 3 way discussion? Or is it more common to get all of the info from the client, and then pass it onto the designer, and act as a back and forth middleman? Afterall, I am the designer's client. Any insight into this would be great

• Asciifi Is a Lightening Fast Web-Based ASCII Converter

  - by Jason Fitzpatrick

  If you have a hankering from some old-school ASCII artwork, Asciifi is a free and lightening fast HTML5 ASCII converter. Despite the simplicity of ASCII images (pictures created not out of a grid of colored pixels like a standard digital photograph but out of a grid of text characters) many ASCII converters are rather slow. Asciifi speeds up the process by rendering your images on the fly with a snappy HTML5-based converter. Visit the site, drag and drop your image, and almost instantaneously you’ll see the results. The output can be further tweaked by adjusting the line width and the character set used. Hit up the link below to take it for a test drive.

• Web development tools/approaches?

  - by Clinton

  My day job involves a bit of programming, but I've recently been attempting some web development for personal reasons. I've got Drupal up and running and done basic things like add new content (i.e. heading and text) and add modules and themes, but I'm not sure how to approach actually designing pages. When I mucked around with webpages 15 years ago, it was just a mixture of HTML, CSS and Javascript, generally written with a text editor. Have things changed, or is this the way I'd make a Drupal page today? If it makes a difference, in my case the page's I want to design simply have static content, but I'd like them to be easily updatable.

• Java web UI framework like ASP.NET MVC?

  - by Ethel Evans

  I'm doing some web apps for personal projects that might be shared out with my friends. I'm trying to use skills that will help me at work, but don't have $$ to spend on Visual Studio right now and don't want to try to cobble something together with Express Editions. Since I've been sort of wanting to bring my Java skills up to date and the main skills I want to work on are design and architecture skills, this isn't a big deal - except that I have no idea how to track down the right UI framework. I know I want something based on MVC, to get more practice with frameworks for that design pattern (we're using ASP .NET MVC2 at work). The UIs that I'll be making will be pretty simple - data entry, buttons, text, images. They will need AJAX. Any thoughts about which frameworks to look at? I'll be watching the comments, if anyone wants additional clarification on what I'm looking for.

• Is obtrusive JavaScript ever ok?

  - by Petah

  I was thinking that if all the users of a website are required to have JavaScript enabled, Is it ok to use obtrusive JavaScript? I'm all for progressive enhancement, but whats the point when an advanced web applications bounces users at the door if they have an old browser or JavaScript disabled? We have a very slim target audience, and we can tell our target audience what browser and plugins/functionality they are required to have. So you my question is, is mixing JS and HTML alright in that case. Like using onclick attributes.

• Understanding the maximum hit-rate supported by a web-server

  - by SNag

  I would like to crawl a publicly available site (and one that's legal to crawl) for a personal project. From a brief trial of the crawler, I gathered that my program hits the server with a new HTTPRequest 8 times in a second. At this rate, as per my estimate, to obtain the full set of data I need about 60 full days of crawling. While the site is legal to crawl, I understand it can still be unethical to crawl at a rate that causes inconvenience to the regular traffic on the site. What I'd like to understand here is -- how high is 8 hits per second to the server I'm crawling? Could I possibly do 4 times that (by running 4 instances of my crawler in parallel) to bring the total effort down to just 15 days instead of 60? How do you find the maximum hit-rate a web-server supports? What would be the theoretical (and ethical) upper-limit for the crawl-rate so as to not adversely affect the server's routine traffic?

• skills that can't be outsourced- web development related

  - by Matt Derami

  I never know where it's acceptable to post something like this, so please forgive if it's in the wrong place. I'm very interested in going further in to web development; I know a bit of javascript, a bit of php, and so forth, but I'm now seeing these services that will go from psd to wordpress for 200 bucks and I'm wondering how the hell is anyone able to compete with this? So I'm wondering if those more knowledgeable than me could tell me what areas are the least likely to be able to be outsourced, for 5 bucks to some kid in Uzbekistan( no offense to that kid).. do you think it's on the database management side, or maybe app development? ideas appreciated.

• Has Microsoft stopped offering the free Internet Explorer Application Compatibility VPC Image for IE 6 testing?

  - by Paul D. Waite

  For some time now, Microsoft has made available free, stripped-down, time-limited Virtual PC images for testing web apps in older versions of IE. The most recent version is here: http://www.microsoft.com/download/en/details.aspx?id=11575 But the XP VPC image has now expired (14th Aug 2011), meaning one can no longer test IE 6 using this method. Have Microsoft made updated XP VPC images available? If not, have they commented on the situation? Do they provide any alternative method to test web apps in IE 6? Update As noted by @PleaseStand, as of 16th Aug 2011, Microsoft has made updated images available that expire on 17th November 2011.
