• What's the better user experience: Waiting once at startup for a long time or waiting frequently for a short time?

  - by Roflcoptr

  I'm currently design an application that involves a lot of calculation. Now I have generally two possibilities which I have both tested: 1) During startup of the application I calculated only the most important values and these values that consume a lot of time. So the user has to wait approximately 15 seconds during startup. But on the other hand a lot of user interactions require recalculation so that the user often has to wait 2-3 seconds after clicking somewhere until the application has calculated and loaded all values 2) I load everything during startup. This takes from 90 to 120 seconds... This is quite a long time, but the big advantage is that all the user interactions are executed immediately. So what would you generally consider the better approach? Loading all time-consuming operations during startup or when needed?

• Sub routing in a SPA site

  - by Anders

  I have a SPA site that I'm working on, I have a requirement that you can have subroutes for a page view model. Im currently using this 'pattern' for the site MyApp.FooViewModel = MyApp.define({ meta: { query: MyApp.Core.Contracts.Queries.FooQuery, title: "Foo" }, init: function (queryResult) { }, prototype: { } }); In the master view model I have a route table this.navigation(new MyApp.RoutesViewModel({ Home: { model: MyApp.HomeViewModel, route: String.empty }, Foo: { model: MyApp.FooViewModel } })); The meta object defines which query should populate the top level view model when its invoked through sammyjs, this is all fine but it does not support sub routing My plan is to change the meta object so that it can (optional offcourse) look like this meta: { query: MyApp.Core.Contracts.Queries.FooQuery, title: "Foo", route: { barId: MyApp.BarViewModel } } When sammyjs detects a barId in the query string the Barmodel will be executed and populated through its own meta object. Is this a good design?

• DIY Camera Carrier Turns any Bag into a Camera Bag

  - by Jason Fitzpatrick

  The biggest problem with camera bags is that they look like camera bags and thus become a perfect target for thieves. This DIY camera carrier lets you slip a lens and camera holder into any bag to help conceal and protect your gear. The project comes to us courtesy of Joy, a designer and crafter, and her adventures in making a DIY camera carrier to help protect her camera while carrying it discretely in her purse. You’ll need some basic sewing skills and access to a sewing machine; to follow along check out the link below and adjust the dimensions of her design to fit your bag.

• A New Experience

  - by Calum

  So a couple of weeks ago, after a fraction over 12 years, I bade farewell to the Solaris Desktop team to join the team whose blog you're reading now: Oracle's Systems Experience Design team, known internally as sxDesign, which has a wider but still largely Solaris-focused usability remit.1 There's been a good deal of overlap and collaboration between the two teams over the years anyway, so it's not exactly a step into the unknown. The elders among you might remember a GNOME 1.4 usability study I presented at GUADEC in 2001, for example, which was primarily the handiwork of a previous incarnation of sxDesign… I pretty much just turned up at the end to steal the glory for the Desktop team. In your face, people I'm going to be working with now!2 1 A move I was first approached about making in about 2003, I think… who says I'm rubbish at making snap decisions? 2 I'm not really. They all left years ago.

• Migrating from a wordpress.com to wordpress.org blog without harming SEO

  - by kikio

  I've had a Wordpress.com weblog for 3 years. And its pages have a good pagerank and are shown in first search results pages. Because of the limitations, I should migrate to my own WordPress. How to migrate safely with the minimum SEO problems? (I know how to export content in wordpress.com and import it to a new wordpress.org blog.) Note 1: links structure and site design are different on the new wordpress blog. (I don't like wordpress.com links structure :| ) Note 2: as you know, it's not possible to edit .htaccess file on wordpress.com. so I can't use 301 redirects.

• Great Discussion of ETL and ELT Tooling in TDWI Linkedin Group

  - by antonio romero

  All, There’s a great discussion of ETL and ELT tooling going on in the official TDWI Linkedin group, under the heading “How Sustainable is SQL for ETL?” It delves into a wide range of topics: The pros and cons of handcoding vs. using tools to design ETL ETL (with separate transformation engines) vs. ELT (transforms in the database) and push-down solutions The future of ETL and data warehousing products A number of community members (of varying affiliations) have kept this conversation going for many months, and are learning from each other as they go. So check it out… Also, while you’re on Linkedin, join the Oracle ETL/Data Integration Linkedin group (for both OWB and ODI users), which recently passed the 2000 member mark.

• "Email This" button with sideways counter

  - by aendrew

  I've been asked to build a design that has a "share this" area like below: I've built every aspect except the Email part of it -- any idea how best to do that? I've found http://getmailcounter.com/, but that displays a counter above. I'd personally just do a link, but it seems they're wanting some sort of analytics built in... Failing that, does anyone know of some sort of sharing system that looks like that and has all of those options? I'd just use AddThis, but its designs don't look very close to that... Thanks!

• Time/duration handling in strategic game

  - by borg

  I'm considering developing a space opera game, having already done some game design. Technically, though, I'm coming from a business applications background. Hence I don't really know how I should handle time and duration. Let's state the matter clearly: what if something is bound to happen in 5 hours and on which other events depend. For example the arrival of some space ship in some system where some defense systems are present, hence a fight would start. Should I use some kind of scheduler (like Quartz in my java land) to trigger the corresponding event when due (I plan to use events for communication)? Something else?

• Scrum: How to work on one story at a time

  - by Juergen

  I was nominated as scrum master in a new formed scrum team. We have already done some sprints. In the beginning I tried to make my team to work on one story at a time. But it didn't work. My team had difficulties to distribute the tasks in a way that they can work simultaneously on one story. Maybe we are doing something wrong? For example: we have a story to create a new dialog. We create the following tasks: Create Model classes Read model data from database Connect model classes with view Implement dialog handling Save data on close Test Documentation Solution Description Can theses tasks be done by more than one person at a time? The tasks - more or less - build upon each other. Or do we design the tasks in a wrong way?

• Do I need a degree in Computer Science to get a junior Programming job?

  - by t84

  Do I need to go to Uni to get a job as a Junior C# coder? I'm 26 and have been working in Games (Production) for 6 years and I am thinking of a change, I've had exposure to VB6, VBA, HTML, CSS, PHP, JavaScript over the past few years and did a web design NCFE at College, but other than that, nothing else! I'm teaching myself C# at the moment with books and I was wondering 'how much' I need to learn and also how I can improve my chances of getting a programming job! Am I a late started to learn coding? (I know many people who started at a very young age!) Thanks for the help :)

• Is the C programming language still used?

  - by Pankaj Upadhyay

  I am a C# programmer, and most of my development is for websites along with a few Windows application. As far as C goes, I haven't used it in a long time, as there was no need to. It came to me as a surprise when one of my friends said that she needs to learn C for testing jobs, while I was helping her learn C#. I figured that someone would only learn C for testing only if there is development done in C. In my knowledge, all the development related to COM and hardware design are also done in C++. Therefore, learning C doesn't make sense if you need to use C++. I also don't believe in historic significance, so why waste time and money in learning C? Is C is still used in any kind of new software development or anything else?

• Does software rot refer primarily to performance, or to messy code?

  - by Kazark

  Wikipedia's definition of software rot focuses on the performance of the software. This is a different usage than I am used to; I had thought of it much more in terms of the cleanliness and design of the code—in terms of the code's having all the standard quality characteristics: readability, maintainability, etc. Now, performance is likely to go down when the code becomes unreadable, because no one knows what is going on. But does the term software rot have special reference to performance? or am I right in thinking it refers to the cleanliness of the code? or is this perhaps a case of multiple senses of the term being in common usage—from the user's perspective, it has do with performance; but for the software craftsman, it has to do more specifically with how the code reads?

• Is Haskell's type system an obstacle to understanding functional programming?

  - by FarmBoy

  I'm studying Haskell for the purpose of understanding functional programming, with the expectation that I'll apply the insight that I gain in other languages (Groovy, Python, JavaScript mainly.) I choose Haskell because I had the impression that it is very purely functional, and wouldn't allow for any reliance on state. I did not choose to learn Haskell because I was interested in navigating an extremely rigid type system. My question is this: Is a strong type system a necessary by-product of an extremely pure functional language, or is this an unrelated design choice particular to Haskell? If it is the latter, I'm curious what would be the most purely functional language that is dynamically typed. I'm not particularly opposed to strong typing, it has its place, but I'm having a hard time seeing how it benefits me in this educational endeavor.

• Securing data inside Azure SQL? Any good libraries or DIY?

  - by Sid

  Azure SQL doesn't support many of the encryption features found in SQL Server (Table and Column encryption). We need to store some sensitive information that needs to be encrypted and we've rolled our own using AesCryptoServiceProvider to encrypt/decrypt data to/from the database. This solves the immediate issue (no cleartext in db) but poses other problems like Key rotation (we have to roll our own code for this, walking through the db converting old cipher text into new cipher text) metadata mapping of which tables and which columns are encrypted. This is simple with it's a few but quickly gets out of hand ... So are there any libraries out there that do this well? Any other resources or design patterns I can be pointed to?

• jMonkey Quest Database

  - by theJollySin

  I am building a game in jMonkey (Java) and I have so far only used default quest text. But now I need to start populating a lot of quests with text. My design requires A LOT of quests texts. What is the best way to build a database of quest texts in jMonkey? I don't have a lot of real experience with databases. Is there a database that integrates well with jMonkey? Here are the ideal properties I want in my database, in order of priority: Reasonably light learning curve Easy portability (in Java) to Windows, Linux, and Mac OSX Good interface with Java Good interface with jMonkey The ability to add properties to the quests: ID, level, gender, quest chain ID, etc. Or am I wrong in thinking I need to use some giant monster like SQL? I haven't been able to find much information on this, so are people using some non-database methods for storing things like quest text in jMonkey?

• Microsoft StyleCop is now Open Source

  - by Scott Dorman

  I have previously talked about Microsoft StyleCop. For those that might not know about it, StyleCop is a source analysis tool (different from the static analysis that FxCop performs) that analyzes the source code directly. As a result, it focuses on more design (or style) issues such as layout, readability and documentation. In an interesting move (and one that I am happy to see), Microsoft has decided to make StyleCop an open source project (under the MS-PL license) available on CodePlex. (The project site isn’t up  yet, but should be in the next few weeks.) This will give the development community the opportunity to help contribute to the project, expanding support to other languages (currently it only supports C#), adding features, and fixing bugs. Shortly after the CodePlex site is up, StyleCop 4.4 will be released which includes support for C# 4.0 as well as a large number of bug fixes and other improvements.

• Tell Visual Studio 2012 UI Designers What to Fix

  - by Ken Cox [MVP]

  If you hate the default interface themes in Visual Studio 2012 as much as I do, you have another outlet to vent. The UI designers have posted a survey where you can tell them how distracting and annoying you find the gray themes and black icons. You even get to comment on the (fixable) all-caps issue. The UI people didn’t listen much to the (largely hostile) developer feedback during the product design – or more likely were constrained by some edict from on high - but seem more willing now to create decent themes for updates. Here’s the Visual Studio 2012 Visual Theme survey URL https://illumeweb.smdisp.net/collector/Survey.ashx?Name=VS2012ThemeSurvey VS 2012 is a great product hampered by a lousy UI. If I could have a Visual Studio 2010 theme (with its coloured icons) I’d be more than satisfied with the 2012 release.

• How do I learn Python from zero to web development? [closed]

  - by Terence Ponce

  I am looking into learning Python for web development. Assuming I already have some basic web development experience with Java (JSP/Servlets), I'm already familiar with web design (HTML, CSS, JS), basic programming concepts and that I am completely new to Python, how do I go about learning Python in a structured manner that will eventually lead me to web development with Python and Django? I'm not in a hurry to make web applications in Python so I really want to learn it thoroughly so as not to leave any gaps in my knowledge of the technologies involving web development in Python. Are there any books, resource or techniques to help me in my endeavor? In what order should I do/read them? UPDATE: When I say learning in a structured manner, I mean starting out from the basics then learning the advanced stuff without leaving some of the important details/features that Python has to offer. I want to know how to apply the things that I already know in programming to Python.

• C#/.net features to cut off assuming no backward compatibility needed?

  - by Gulshan

  Any product or framework evolves. Mainly it's done to catch up the needs of it's users, leverage new computing powers and simply make it better. Sometimes the primary design goal also changes with the product. C# or .net framework is no exception. As we see, the present day 4th version is very much different comparing with the first one. But thing comes as a barricade to this evolution- backward compatibility. In most of frameworks/products there are features would have been cut off if there was no need to support backward compatibility. According to you, what are these features in C#/.net? Please mention one feature per answer.

• Physical effects of long term keyboard use- what does the science say and what factors affect it?

  - by glenatron

  This question asks about the ergonomics of a particular keyboard for long programming hours, what I would like to know is about the ergonomics of using a keyboard in general. What are the most significant risks associated with it and how can they best be mitigated? Do the "ergonomic" keyboard designs make a difference and if so which design is most effective? If not do other factors such as wrist-rests, regular exercise or having a suitable height of chair or desk make a difference? Do you have any direct experience of problems deriving from keyboard use and if so how did you resolve them? Is there any good science on this and if so what does it indicate? Edited to add: Wikipedia suggests that there are no proven advantages to "ergonomic" keyboards, but their citation seems pretty old- is that still the current state of play?

• So long wizards!

  - by geekrutherford

  In an effort to make an application more robust I have been switching to a server-side method of tracking record selections vs. client side.   The pages relying on record selections utilized the ASP.NET Wizard control which seemed like a good idea originally. Unfortunately, the design of the control is not all that flexible. It appears to want to center everything vertically which might not be a problem if it did not always use the vertical size of the largest Wizard Step for positioning.   So, I am ripping out the Wizard controls and replacing with simple Panel controls that are turned on/off. Much cleaner and presentable.

• How do you visually represent programming skills?

  - by TomSchober

  I had a discussion with a recruiter recently that made me wish I could visually represent programming skills. In trying to explain how skills relate, what are the important properties of those skills? Would a tagging model work (i.e. "Design Pattern," "Programming Language," "IDE," or "VCS")? Are they really hierarchical? Clarification: The real problem I see is communicating the level of granularity among skill sets. For instance saying someone "knows Java" is a uselessly broad term in describing what someone can DO. However saying they know how to write web services with the Java Programming language is a bit better. To go even further, saying they know Spring as a tool under all that is probably specific enough. What should we call those levels of granularity? What are the relationships between the terms we use? i.e. Framework to Language, Tool to Language, Framework to Solution(like web services), etc.
