• Optimizing data downloaded via 'link' media queries and asynchronous loading

  - by adam-asdf

  I have a website that tries to make sensible use of media queries and avoid 'expensive' CSS for users of mobile devices. My eventual goal is to make it 'mobile-first' but for now, since it is based on Twitter Bootstrap it isn't. I included some background images (Base64 encoded) and styles that would only apply to "full-size" browsers in a separate stylesheet loaded asynchronously via modernizr.load. In Firefox (but not webkit browsers) it makes it so that if you navigate away from the homepage and then return, the content (specifically, all those extras) 'blinks' when it finishes loading...or maybe I should say reloading. If, instead of using modernizr.load, I include that stylesheet via a link... in the head with a media query attribute will it prevent the data from being downloaded by non-matching browsers (mobile, based on screensize) that it is inapplicable to?

• Pay for Graphic Designer vs Programmer

  - by FrankSinatra

  In a corporate web-design setup, who typically makes more per hour, the graphic designer or the programmer? By graphic designer, I mean somebody who builds mockups probably in photoshop, selects font-styles, colors, etc. Most things layout-wise are near pixel-perfect, but likely after the initial implementation by the programmer, there will be a lot of small changes directed by the graphic designer. By programmer, I mean somebody who is coding the CSS, the HTML, and light backend support, probably in PHP. The programmer will attempt to duplicate the mockups given the limitations of the medium, and consult with the graphic designer afterwards on what changes are tangible and which are not. Both probably have an undergraduate degree from a respected four-year institution.

• Single or multiple return statements in a function [on hold]

  - by Juan Carlos Coto

  When writing a function that can have several different return values, particularly when different branches of code return different values, what is the cleanest or sanest way of returning? Please note the following are really contrived examples meant only to illustrate different styles. Example 1: Single return def my_function(): if some_condition: return_value = 1 elif another_condition: return_value = 2 else: return_value = 3 return return_value Example 2: Multiple returns def my_function(): if some_condition: return 1 elif another_condition: return 2 else: return 3 The second example seems simpler and is perhaps more readable. The first one, however, might describe the overall logic a bit better (the conditions affect the assignment of the value, not whether it's returned or not). Is the second way preferable to the first? Why?

• "A", "an", and "the" in method and function names: What's your take?

  - by Mike Spross

  I'm sure many of us have seen method names like this at one point or another: UploadTheFileToTheServerPlease CreateATemporaryFile WriteTheRecordToTheDatabase ResetTheSystemClock That is, method names that are also grammatically-correct English sentences, and include extra words purely to make them read like prose. Personally, I'm not a huge fan of such "literal" method names, and prefer to be succint, while still being as clear as possible. To me, words like "a", "an", and "the" just look plain awkward in method names, and it makes method names needlessly long without really adding anything useful. I would prefer the following method names for the previous examples: UploadFileToServer CreateTemporaryFile WriteOutRecord ResetSystemClock In my experience, this is far more common than the other approach of writing out the lengthier names, but I have seen both styles and was curious to see what other people's thoughts were on these two approaches. So, are you in the "method names that read like prose" camp or the "method names that say what I mean but read out loud like a bad foreign-language-to-English translation" camp?

• It's 2011 - why do I still have to use tables for email?

  - by John Isaacks

  This might seem like a rant, but I am curious. CSS replaced tables for layout a long time ago. But we still have to use tables for layout when creating rich emails. Why is this? Are there any other options? Are there really technical constraints that prevent CSS from working in an email. What are they? I can see how linked or embedded style sheets might be a problem, but not even inline styles work. Is this ever going to change?

• Why is JavaScript not used for classical application development (compiled software)?

  - by Jose Faeti

  During my years of web development with JavaScript, I come to the conclusion that it's an incredible powerful language, and you can do amazing things with it. It offers a rich set of features, like: Dynamic typing First-class functions Nested functions Closures Functions as methods Functions as Object constructors Prototype-based Objects-based (almost everything is an object) Regex Array and Object literals It seems to me that almost everything can be achieved with this kind of language, you can also emulate OO programming, since it provides great freedom and many different coding styles. With more software-oriented custom functionalities (I/O, FileSystem, Input devices, etc.) I think it will be great to develop applications with. Though, as far as I know, it's only used in web development or in existing softwares as a scripting language only. Only recently, maybe thanks to the V8 Engine, it's been used more for other kind of tasks (see node.js for example). Why until now it's only be relegated only to web development? What is keeping it away from software development?

• Kansas City SQL Saturday 2012: BBQ Crawl

  - by Bill Graziano

  The next Kansas City SQL Saturday is coming up on August 4th.  We’ll have the usual SQL Saturday goodness: lots of technical sessions, great networking events and a fantastic speaker dinner.  And we’ll have the Third Annual Kansas City SQL Saturday BBQ Crawl.  On Friday afternoon we’ll visit a few BBQ places in town.  We tend to order big sampler plates and just share everything around.  It’s a great way to try a variety of styles.  This year we’ll be hitting an all new selection of BBQ joints. You don’t need to be a speaker to attend.  However the call for speakers is open until June 28th (hint, hint).  Locals and out-of-towners are all welcome. If you’re interested in attending send me an email and I’ll get you added to the list. We finish in plenty of time to get you to the speaker dinner – as if you could eat any more.

• css - use universal '*' selector vs. html or body selector?

  - by Michael Durrant

  Applying styles to the body tag will be applied to the whole page, so body { font-family: Verdana } will be applied to the whole page. This could also be done with * {font-family: Verdana} which would apply to all elements and so would seem to have the same effect. I understand the principle that in the first instance the style is being applied to one tag, body for the whole page whereas in the second example the font is being applied against each individual html elements. What I am asking is what is the practical difference in doing that, what are the implications and what is a reason, situation or best practice that leads to using one over another. One side-effect is certainly speed (+1 Rob). I am most interested in the actual reason to choose one over the other in terms of functionality.

• Reusing elements in StandardStyles.xaml

  - by nmarun

  In one of my previous blogs (second point) , I mentioned not to modify the StandardStyles.xaml, but instead to create your own resource dictionary. I also mentioned how to declare your custom styles dictionary in the App.xaml file. If you want to reference or build upon from an existing style in the StandardStyles.xaml file, do the following: 1. Remove the entry for StandardStyles.xaml in the App.xaml file 2. Add your custom resource dictionary in the App.xaml file 1: <!-- App.xaml --> 2: <...(read more)

• Multiple style sheets best practice

  - by user1145927

  I currently am working on a project which has one large style sheet for about 20 pages. The style sheet contains some styles which are specific for certain pages. I'd like to break the style sheet up so there is one style sheet for each page with one master style sheet that handles everything generic. The reason I want to do this is so people can work on multiple pages without having to worry about who has that large style sheet checked out (I'm using TFS). Is this good practice?

• Is there a way to specify a CSS3 transition to occur only on :hover and when returning from hover, not on every event? [closed]

  - by Steve

  You could define the transition on the :hover event, which causes the browser to render only the effect into the hover and not out of it. a:hover { transition... } Using scale as an example, an image being scaled up would scale up on hover, but go straight back down without any transition when the cursor leaves the image. Or, you can set the transition on the element directly: a { transition... } Which by definition means any change that effects the scale of the element such as any developer set styles will work, but also the user zooming in and out the page, will cause there to be a transition. All the tutorials being spewed onto the internet at the moment point to using the latter, but wouldn't one consider this a usability flaw for anyone wanting to resize the page or taking any other action that may cause similar scenarios? Pages with large amounts of transitional hover scaling can go pretty mental if you zoom in and out of them.

• Export from EndNote into MySQL database

  - by Tomba

  I would like to export some records from an EndNote (reference management software) library and import into a MySQL database. Does anyone have any experience with this? I've tried creating custom EndNote "output styles" containing either comma-delimited values or even SQL code, but have had mixed results, either because EndNote filters out some characters (like `) or because EndNote doesn't (or I can't work out how to make it) escape text, which might include characters like ' and ". I realize this might be a bit off-topic but any help would be appreciated.

• Get the 'actual font' being used for a WPF element

  - by mackenir

  WPF lets you specify the FontFamily of TextBlocks, Buttons, etc. Is there a way to discover what font WPF decided to use for a given element? For example, if you leave the FontFamily unspecified, styles notwithstanding, an element will take on the Font Family 'GlobalUserInterface'. In this case, can I determine programmatically what font is actually being used to render an element's text?

• Delphi 2010 Professional and remote database access

  - by Kico Lobo

  Hi, When looking for which version of Delphi 2010 to buy, we found the following limitation on the professional one: Delphi 2010 Professional is designed for developers building high-performance desktop GUI and touch-screen applications with (or without) embedded and local database persistence. What does this really mean? Does this mean that we'll only face this restriction if we choose to use the native vcl components for database access we'll face this restriction. And what if we choose to use ADO components instead of those? In this case, how can Delphi avoid us to access remote database servers? Did anyone here ever tried this? Going even further: if we choose to use a database like Firebird, which is just one file, and used a network mapped drive. Could we be facing the same limitation? Supposing we opt for ADO, what will be the main consequences?

• Delphi 2010 Error Insight incorrectly flags "Undeclared Identifier"

  - by user257188

  In D2010, Error Insight is incorrectly underlining in red types like "TOpenDialog" (even though my unit and project's uses both include Dialogs). Also, in my method TMyFrame.Foo, it fails the same way by flagging a reference to a VCL component in my TMyFrame -- even though Foo and the component are both part of TMyFrame. SO suggested I read several threads on this subject. One mentions a D2009 fix for this. Is there a D2010 fix? Other postings have suggested that Error Insight yields too many false alarms and should just be turned off. Any suggestions?
