  • Windows 8: Multiple monitors with varying DPI? [closed]

    - by Sid
    Possible Duplicate: Dual monitors on Windows - How do I set a different DPI or text size on each monitor? I'm running Windows 8 on my Macbook Pro Retina (220dpi) which has an external 24" monitor (~96 dpi). In Mac OS 10.8.2, the display settings seem ok and I can actually use both displays without usability issues. I don't know what scaling settings etc it uses but it looks fine. On Windows 8, however when I boost the DPI settings to take advantage of the retina display, it blows up the display on the external monitor - text is giant sized. How can I tell Windows 8 to use the real DPI settings of each monitor? NOTE: I'm not asking for Windows 7.

  • Bikeshedding: Placeholders in strings

    - by dotancohen
    I find that I sometimes use placeholders in strings, like this: $ cat example-apache <VirtualHost *:80> ServerName ##DOMAIN_NAME## ServerAlias www.##DOMAIN_NAME## DocumentRoot /var/www/##DOMAIN_NAME##/public_html </VirtualHost> Now I am sure that it is a minor issue if the placeholder is ##DOMAIN_NAME##, !!DOMAIN_NAME!!, {{DOMAIN_NAME}}, or some other variant. However, I now need to standardize with other developers on a project, and we all have a vested interest in having our own placeholder format made standard in the organization. Are there any good reasons for choosing any of these, or others? I am trying to quantify these considerations: Aesthetics and usability. For example, __dict__ may be hard to read as we don't know how many underscores are in there. Compatibility. Will some language try to do something funny with {} syntax in a string (such as PHP does with "Welcome to {$siteName} today!")? Actually, I know that PHP and Python won't, but others? Will a C++ preprocessor choke on ## format? If I need to store the value in some SQL engine, will it not consider something a comment? Any other pitfalls to be wary of? Maintainability. Will the new guy mistake ##SOME_PLACEHOLDER## as a language construct? The unknown. Surely the wise folk here will think of other aspects of this decision that I have not thought of. I might be bikeshedding this, but if there are real issues that might be lurking then I would certainly like to know about them before mandating that our developers adhere to a potentially-problematic convention.

  • What service or software should I use to serve advertising on a site with about 120k monthly page views?

    - by JasonBirch
    I have a site that is generating about 120k monthly page views and is being hosted on a shared FreeBSD server where I have access to PHP and MySQL. I am using some custom PHP server-side scripts that give each of my ad networks (AdSense, Tribal Fusion, etc) an adjustable percentage of impressions in each of the ad positions on my pages. I am looking for a better way of managing and measuring the delivery of these ads, and would also like to be able to take direct placements and provide statistics to the clients. I am looking at options including OpenX self-hosted, OpenX community, and Google DoubleClick for Publishers Small Business (DFP), but am having difficulty determining which one will best meet my needs. They all seem to have pretty steep learning curves compared to my simple scripts. What I have taken away so far as the benefit of self-hosting is that I don't have to pay for the service if I exceed a maximum number of ad impressions, while both OpenX Community and DFP have free impression limits. Of course, if I was doing those kind of numbers I'd need to upgrade my hosting account, but I'm not sure even at that point whether it would be cheaper to serve the ads myself than pay for a premium service. Apart from this, I really need insights into what features differentiate these services, why I might want to choose one over another, and if there are any other competing products or service of the same quality that I should look into. Answers from webmasters who have used both (or all three) services and can talk to usability and ease of ad management would be highly appreciated.

  • Release Notes for 7/6/2012

    Happy belated 4th of July, everyone! Here are the notes for this week’s release on CodePlex: Implemented performance improvements to Git repositories. Fixed an issue that caused the final “click here” download link to fail in projects that display ads. Fixed an issue for certain projects that made it impossible to edit releases. Fixed an issue where the URL for a diff of a file would not take users to the diff in question. Fixed a rare issue that prevented a small subset of projects from modifying their project details. Fixed an issue where scrollbars were missing in our side-by-side diff viewer. Super- and sub-scripts now work properly in documentation. Addressed several usability issues around the diff viewer. Fixed an issue where the scrollbar could disappear in the advanced issue tracker if a user opens a modal dialog. Have ideas on how to improve CodePlex? Visit our ideas page!

  • What's the best way to install software in Ubuntu?

    - by the0ther
    I'm new to Ubuntu and have been away from Linux for a while. I'm used to Windows and find this tedious on Linux but I want to give it a shot. My tendency is to prefer GUI tools over command-line, and Ubuntu is a distro that seems to cater to usability. I note it is based somewhat on apt-get which I've heard good things about. What's the best practise for installing apps on Ubuntu? Should I prefer to try my options in this order? Synaptic Package Manger apt-get on the command line .tar.gz files (old school)

  • When should I decline to make a requested change?

    - by reuscam
    I work on the software side of a company that provides custom hardware with software running on top of it. Often times the hardware is not engineered well. In those cases, I am often asked first to troubleshoot the problem - of course the symptom is always "your software crashed" or something along those lines. Just recently we had another one of these incidents where power on a USB line is not reliable, and it causes a USB device to fail. This causes a usability problem in one of our applications. I have been asked by upper management to handle this better - continually monitor the USB device, and if it disappears, then reboot, or try to reset it. Doing either of these is not guaranteed to fix anything. Ultimately, the real fix is to correct the reliability of the device from the hardware side. I could improve performance, but not to 100%, and of course I would be using my already limited time to bloat code and add yet another device monitoring thread. So with all that said, how do I make a good decision about when to say that this needs to be a hardware fix, and only a hardware fix? Can I approach this quantitatively, and come up with some sort of definitive yes/no test? I'm sure its not that easy.

  • What's an alternative to using public folders (in Outlook)?

    - by Ivo Flipse
    My colleagues abuse our mail servers public folders to store (old) emails so that everyone can read them using IMAP. I'm looking into good alternatives after reading this Tech Republic article: "10 reasons why you should begin phasing out Exchange public folders" The most important thing they need is access to emails from multiple computers without overloading our network. So do you have any suggestions for alternatives? If there's a nice combination with some CRM system it would be interesting too. Note: this doesn't have to be freeware, usability and efficiency are more important. The solution has to be Windows 32 bit only

  • What happened to the ability to go back in a already-loaded YouTube video?

    - by Chelonian
    For many years, my experience with YouTube had been, consistently and on any computer/browser, that once a section of that video were loaded, or the whole video, if you wanted to see an earlier part of the video again, you could simply click on the loading bar to that area and you would instantly go to that part. More recently (6 months?) this has changed. Now, clicking in an earlier part of the video forces a reload of the whole video (that is, the grey bar goes back to 0) and you have to hope your loading will be fast enough to make waiting to watch it again even worth it. It is a huge regression in usability for me. Is there any way to watch YouTube videos in the "old way"? I use Firefox 17.0.1 at this point and have an updated (I think) Flash, but I'd be willing to try other browsers or versions if it made a difference.

  • Make all text EXCEPT <input> unselectable in Internet Explorer? [migrated]

    - by Ashli
    I have a website where I want to disable users from selecting content EXCEPT for input areas. I currently have some CSS to disable user-select: -webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -o-user-select: none; user-select: none; However, this does NOT cover Internet Explorer; thus, I need to implement some JavaScript: <body onselectstart="return false;"> Through CSS and JavaScript, I can make all content unselectable across all popular browsers. BUT, this code also makes areas unselectable, which is a major case of poor usability. I use CSS to make input areas selectable: -webkit-user-select: text; -khtml-user-select: text; -moz-user-select: text; -o-user-select: text; user-select: text; .. and as you might have expected, this does not cover Internet Explorer, since I used JavaScript to disable all content from being selectable. What can I do to make all content unselectable except for input areas?

  • Diagramming Software for a Developer/Designer

    - by Craig Walker
    For a long time I've been looking for a good diagramming/vector-based drawing program that meets my needs as a developer. I'd like to: Draw database diagrams Draw flow charts Draw object-modeling diagrams (UML being the standard) Draw other free-form diagrams (basically boxes & arrows with the occasional clipart) Draw mockups of user interfaces and web pages EDIT: I want good-looking electronic-format diagrams that I can show to 3rd parties, not just something for my own internal use. EDIT 2: I'm also looking for Windows software, although I'm toying with the idea of switching to Mac, so a really good Mac-only product might get me to switch. Basically I need a good vector graphic program (with decent grouping, connecting lines, and ideally auto-routing). I'd prefer a diagramming tool that can also be used for drawing (for the UI mockups) rather than a drawing tool that can also be used for diagrams. I've tried Visio on several occasions, and every time I've been disappointed. The interface always seems to get in my way at some point. It's pretty close to what I want, and the latest version (I got the trail from MS) seems to be better than previous ones in terms of usability, but I really don't want to plunk down that sort of cash for a mediocre product. I've tried Dia and Inkscape, and while initially promising and with the right price tag, I found both of them to be lacking in several ways (including some recurring bugs). I've toyed with getting Adobe Illustrator, but I've never used it before, and I have a feeling that it wouldn't handle the diagramming aspect very well, and I don't want to buy a copy just to find out it doesn't meet my needs. So far, the product that I've had the most success with is, sadly, OpenOffice Draw. It's free of course (which lowers my expectations and thus improves my view of it) and its usability is pretty good, but in the end I'd like something more suited to diagramming. I'm willing to spend real money (in the $500-$1K range) for a really good piece of software if it does everything I want it to. The front runner is of course Visio but I'm hoping for more. Does anybody have any recommendations? CONCLUSION: @dlamblin had the most informative post, but the part I gained the most from was his/her (and others) mention of OmniGraffle, not Gliffy. I gave Gliffy a try, and it seemed neet for occational use, but since it's a Flash app (note: not AJAX as dlamblin mentioned) it's still a bit of a pain to use (no keyboard shortcuts for copy/paste was pretty much a deal breaker for me). I also tried SmartDraw, but it had 3-strikes-you're-out against it: The trial period was only 7 days long. It used some nonstandard (and visually jarring) GUI widget toolkit for its UI. At the very least it makes me suspicious (how do I know it will actually work & support the standard Windows features?) It crashed on me early into my trial. OmniGraffle looks like exactly what I want... except that it's Mac-only (so I couldn't give it a try). However, it got good reviews from my Mac-owning coworker, and I hope to try it on a friend's Mac soon. If it's good enough then I might spring for a new MacBook.

  • How do you stop scripters from slamming your website hundreds of times a second?

    - by davebug
    [update] I've accepted an answer, as lc deserves the bounty due to the well thought-out answer, but sadly, I believe we're stuck with our original worst case scenario: CAPTCHA everyone on purchase attempts of the crap. Short explanation: caching / web farms make it impossible for us to actually track hits, and any workaround (sending a non-cached web-beacon, writing to a unified table, etc.) slows the site down worse than the bots would. There is likely some pricey bit of hardware from Cisco or the like that can help at a high level, but it's hard to justify the cost if CAPTCHAing everyone is an alternative. I'll attempt to do a more full explanation in here later, as well as cleaning this up for future searchers (though others are welcome to try, as it's community wiki). I've added bounty to this question and attempted to explain why the current answers don't fit our needs. First, though, thanks to all of you who have thought about this, it's amazing to have this collective intelligence to help work through seemingly impossible problems. I'll be a little more clear than I was before: This is about the bag o' crap sales on woot.com. I'm the president of Woot Workshop, the subsidiary of Woot that does the design, writes the product descriptions, podcasts, blog posts, and moderates the forums. I work in the css/html world and am only barely familiar with the rest of the developer world. I work closely with the developers and have talked through all of the answers here (and many other ideas we've had). Usability of the site is a massive part of my job, and making the site exciting and fun is most of the rest of it. That's where the three goals below derive. CAPTCHA harms usability, and bots steal the fun and excitement out of our crap sales. To set up the scenario a little more, bots are slamming our front page tens of times a second screenscraping (and/or scanning our rss) for the Random Crap sale. The moment they see that, it triggers a second stage of the program that logs in, clicks I want One, fills out the form, and buys the crap. In current (2/6/2009) order of votes: lc: On stackoverflow and other sites that use this method, they're almost always dealing with authenticated (logged in) users, because the task being attempted requires that. On Woot, anonymous (non-logged) users can view our home page. In other words, the slamming bots can be non-authenticated (and essentially non-trackable except by IP address). So we're back to scanning for IPs, which a) is fairly useless in this age of cloud networking and spambot zombies and b) catches too many innocents given the number of businesses that come from one IP address (not to mention the issues with non-static IP ISPs and potential performance hits to trying to track this). Oh, and having people call us would be the worst possible scenario. Can we have them call you? BradC Ned Batchelder's methods look pretty cool, but they're pretty firmly designed to defeat bots built for a network of sites. Our problem is bots are built specifically to defeat our site. Some of these methods could likely work for a short time until the scripters evolved their bots to ignore the honeypot, screenscrape for nearby label names instead of form ids, and use a javascript-capable browser control. lc again "Unless, of course, the hype is part of you

  • Designing for the future

    - by Dennis Vroegop
    User interfaces and user experience design is a fast moving field. It’s something that changes pretty quick: what feels fresh today will look outdated tomorrow. I remember the day I first got a beta version of Windows 95 and I felt swept away by the user interface of the OS. It felt so modern! If I look back now, it feels old. Well, it should: the design is 17 years old which is an eternity in our field. Of course, this is not limited to UI. Same goes for many industries. I want you to think back of the cars that amazed you when you were in your teens (if you are in your teens then this may not apply to you). Didn’t they feel like part of the future? Didn’t you think that this was the ultimate in designs? And aren’t those designs hopelessly outdated today (again, depending on your age, it may just be me)? Let’s review the Win95 design: And let’s compare that to Windows 7: There are so many differences here, I wouldn’t even know where to start explaining them. The general feeling however is one of more usability: studies have shown Windows 7 is much easier to understand for new users than the older versions of Windows did. Of course, experienced Windows users didn’t like it: people are usually afraid of changes and like to stick to what they know. But for new users this was a huge improvement. And that is what UX design is all about: make a product easier to use, with less training required and make users feel more productive. Still, there are areas where this doesn’t hold up. There are plenty examples of designs from the past that are still fresh today. But if you look closely at them, you’ll notice some subtle differences. This differences are what keep the designs fresh. A good example is the signs you’ll find on the road. They haven’t changed much over the years (otherwise people wouldn’t recognize them anymore) but they have been changing gradually to reflect changes in traffic. The same goes for computer interfaces. With each new product or version of a product, the UI and UX is changed gradually. Every now and then however, a bigger change is needed. Just think about the introduction of the Ribbon in Microsoft Office 2007: the whole UI was redesigned. A lot of old users (not in age, but in times of using older versions) didn’t like it a bit, but new users or casual users seem to be more efficient using the product. Which, of course, is exactly the reason behind the changes. I believe that a big engine behind the changes in User Experience design has been the web. In the old days (i.e. before the explosion of the internet) user interface design in Windows applications was limited to choosing the margins between your battleship gray buttons. When the web came along, and especially the web 2.0 where the browsers started to act more and more as application platforms, designers stepped in and made a huge impact. In the browser, they could do whatever they wanted. In the beginning this was limited to the darn blink tag but gradually people really started to think about UX. Even more so: the design of the UI and the whole experience was taken away from the developers and put into the hands of people who knew what they were doing: UX designers. This caused some problems. Everyone who has done a web project in the early 2000’s must have had the same experience: the designers give you a set of Photoshop files and tell you to translate it to HTML. Which, of course, is very hard to do. However, with new tooling and new standards this became much easier. The latest version of HTML and CSS has taken the responsibility for the design away from the developers and placed them in the capable hands of the designers. And that’s where that responsibility belongs, after all, I don’t want a designer to muck around in my c# code just as much as he or she doesn’t want me to poke in the sites style definitions. This change in responsibilities resulted in good looking but more important: better thought out user interfaces in websites. And when websites became more and more interactive, people started to expect the same sort of look and feel from their desktop applications. But that didn’t really happen. Most business applications still have that battleship gray look and feel. Ok, they may use a different color but we’re not talking colors here but usability. Now, you may not be able to read the Dutch captions, but even if you did you wouldn’t understand what was going on. At least, not when you first see it. You have to scan the screen, read all the labels, see how they are related to the other elements on the screen and then figure out what they do. If you’re an experienced user of this application however, this might be a good thing: you know what to do and you get all the information you need in one single screen. But for most applications this isn’t the case. A lot of people only use their computer for a limited time a day (a weird concept for me, but it happens) and need it to get something done and then get on with their lives. For them, a user interface experience like the above isn’t working. (disclaimer: I just picked a screenshot, I am not saying this is bad software but it is an example of about 95% of the Windows applications out there). For the knowledge worker, this isn’t a problem. They use one or two systems and they know exactly what they need to do to achieve their goal. They don’t want any clutter on their screen that distracts them from their task, they just want to be as efficient as possible. When they know the systems they are very productive. The point is, how long does it take to become productive? And: could they be even more productive if the UX was better? Are there things missing that they don’t know about? Are there better ways to achieve what they want to achieve? Also: could a system be designed in such a way that it is not only much more easy to work with but also less tiring? in the example above you need to switch between the keyboard and mouse a lot, something that we now know can be very tiring. The goal of most applications (being client apps or websites on any kind of device) is to provide information. Information is data that when given to the right people, on the right time, in the right place and when it is correct adds value for that person (please, remember that definition: I still hear the statement “the information was wrong” which doesn’t make sense: data can be wrong, information cannot be). So if a system provides data, how can we make sure the chances of becoming information is as high as possible? A good example of a well thought-out system that attempts this is the Zune client. It is a very good application, and I think the UX is much better than it’s main competitor iTunes. Have a look at both: On the left you see the iTunes screenshot, on the right the Zune. As you notice, the Zune screen has more images but less chrome (chrome being visuals not part of the data you want to show, i.e. edges around buttons). The whole thing is text oriented or image oriented, where that text or image is part of the information you need. What is important is big, what’s less important is smaller. Yet, everything you need to know at that point is present and your attention is drawn immediately to what you’re trying to achieve: information about music. You can easily switch between the content on your machine and content on your Zune player but clicking on the image of the player. But if you didn’t know that, you’d find out soon enough: the whole UX is designed in such a way that it invites you to play around. So sooner or later (probably sooner) you’d click on that image and you would see what it does. In the iTunes version it’s harder to find: the discoverability is a lot lower. For inexperienced people the Zune player feels much more natural than the iTunes player, and they get up to speed a lot faster. How does this all work? Why is this UX better? The answer lies in a project from Microsoft with the codename (it seems to be becoming the official name though) “Metro”. Metro is a design language, based on certain principles. When they thought about UX they took a good long look around them and went out in search of metaphors. And they found them. The team noticed that signage in streets, airports, roads, buildings and so on are usually very clear and very precise. These signs give you the information you need and nothing more. It’s simple, clearly understood and fast to understand. A good example are airport signs. Airports can be intimidating places, especially for the non-experienced traveler. In the early 1990’s Amsterdam Airport Schiphol decided to redesign all the signage to make the traveller feel less disoriented. They developed a set of guidelines for signs and implemented those. Soon, most airports around the world adopted these ideas and you see variations of the Dutch signs everywhere on the globe. The signs are text-oriented. Yes, there are icons explaining what it all means for the people who can’t read or don’t understand the language, but the basic sign language is text. It’s clear, it’s high-contrast and it’s easy to understand. One look at the sign and you know where to go. The only thing I don’t like is the green sign pointing to the emergency exit, but since this is the default style for emergency exits I understand why they did this. If you look at the Zune UI again, you’ll notice the similarities. Text oriented, little or no icons, clear usage of fonts and all the information you need. This design language has a set of principles: Clean, light, open and fast Content, not chrome Soulful and alive These are just a couple of the principles, you can read the whole philosophy behind Metro for Windows Phone 7 here. These ideas seem to work. I love my Windows Phone 7. It’s easy to use, it’s clear, there’s no clutter that I do not need. It works for me. And I noticed it works for a lot of other people as well, especially people who aren’t as proficient with computers as I am. You see these ideas in a lot other places. Corning, a manufacturer of glass, has made a video of possible usages of their products. It’s their glimpse into the future. You’ll notice that a lot of the UI in the screens look a lot like what Microsoft is doing with Metro (not coincidentally Corning is the supplier for the Gorilla glass display surface on the new SUR40 device (or Surface v2.0 as a lot of people call it)). The idea behind this vision is that data should be available everywhere where you it. Systems should be available at all times and data is presented in a clear and light manner so that you can turn that data into information. You don’t need a lot of fancy animations that only distract from the data. You want the data and you want it fast. Have a look at this truly inspiring video that made: This is what I believe the future will look like. Of course, not everything is possible, or even desirable. But it is a nice way to think about the future . I feel very strongly about designing applications in such a way that they add value to the user. Designing applications that turn data into information. Applications that make the user feel happy to use them. So… when are you going to drop the battleship-gray designs?

  • The Incremental Architect&acute;s Napkin - #2 - Balancing the forces

    - by Ralf Westphal
    Originally posted on: http://geekswithblogs.net/theArchitectsNapkin/archive/2014/06/02/the-incremental-architectacutes-napkin---2---balancing-the-forces.aspxCategorizing requirements is the prerequisite for ecconomic architectural decisions. Not all requirements are created equal. However, to truely understand and describe the requirement forces pulling on software development, I think further examination of the requirements aspects is varranted. Aspects of Functionality There are two sides to Functionality requirements. It´s about what a software should do. I call that the Operations it implements. Operations are defined by expressions and control structures or calls to frameworks of some sort, i.e. (business) logic statements. Operations calculate, transform, aggregate, validate, send, receive, load, store etc. Operations are about behavior; they take input and produce output by considering state. I´m not using the term “function” here, because functions - or methods or sub-programs - are not necessary to implement Operations. Functions belong to a different sub-aspect of requirements (see below). Operations alone are not enough, though, to make a customer happy with regard to his/her Functionality requirements. Only correctly implemented Operations provide full value. This should make clear, why testing is so important. And not just manual tests during development of some operational feature, but automated tests. Because only automated tests scale when over time the number of operations increases. Without automated tests there is no guarantee formerly correct operations are still correct after more got added. To retest all previous operations manually is infeasible. So whoever relies just on manual tests is not really balancing the two forces Operations and Correctness. With manual tests more weight is put on the side of the scale of Operations. That might be ok for a short period of time - but in the long run it will bite you. You need to plan for Correctness in the long run from the first day of your project on. Aspects of Quality As important as Functionality is, it´s not the driver for software development. No software has ever been written to just implement some operation in code. We don´t need computers just to do something. All computers can do with software we can do without them. Well, at least given enough time and resources. We could calculate the most complex formulas without computers. We could do auctions with millions of people without computers. The only reason we want computers to help us with this and a million other Operations is… We don´t want to wait for the results very long. Or we want less errors. Or we want easier accessability to complicated solutions. So the main reason for customers to buy/order software is some Quality. They want some Functionality with a higher Quality (e.g. performance, scalability, usability, security…) than without the software. But Qualities come in at least two flavors: Most important are Primary Qualities. That´s the Qualities software truely is written for. Take an online auction website for example. Its Primary Qualities are performance, scalability, and usability, I´d say. Auctions should come within reach of millions of people; setting up an auction should be very easy; finding a suitable auction and bidding on it should be as fast as possible. Only if those Qualities have been implemented does security become relevant. A secure auction website is important - but not as important as a fast auction website. Nobody would want to use the most secure auction website if it was unbearably slow. But there would be people willing to use the fastest auction website even it was lacking security. That´s why security - with regard to online auction software - is not a Primary Quality, but just a Secondary Quality. It´s a supporting quality, so to speak. It does not deliver value by itself. With a password manager software this might be different. There security might be a Primary Quality. Please get me right: I don´t want to denigrate any Quality. There´s a long list of non-functional requirements at Wikipedia. They are all created equal - but that does not mean they are equally important for all software projects. When confronted with Quality requirements check with the customer which are primary and which are secondary. That will help to make good economical decisions when in a crunch. Resources are always limited - but requirements are a bottomless ocean. Aspects of Security of Investment Functionality and Quality are traditionally the requirement aspects cared for most - by customers and developers alike. Even today, when pressure rises in a project, tunnel vision will focus on them. Any measures to create and hold up Security of Investment (SoI) will be out of the window pretty quickly. Resistance to customers and/or management is futile. As long as SoI is not placed on equal footing with Functionality and Quality it´s bound to suffer under pressure. To look closer at what SoI means will help to become more conscious about it and make customers and management aware of the risks of neglecting it. SoI to me has two facets: Production Efficiency (PE) is about speed of delivering value. Customers like short response times. Short response times mean less money spent. So whatever makes software development faster supports this requirement. This must not lead to duct tape programming and banging out features by the dozen, though. Because customers don´t just want Operations and Quality, but also Correctness. So if Correctness gets compromised by focussing too much on Production Efficiency it will fire back. Customers want PE not just today, but over the whole course of a software´s lifecycle. That means, it´s not just about coding speed, but equally about code quality. If code quality leads to rework the PE is on an unsatisfactory level. Also if code production leads to waste it´s unsatisfactory. Because the effort which went into waste could have been used to produce value. Rework and waste cost money. Rework and waste abound, however, as long as PE is not addressed explicitly with management and customers. Thanks to the Agile and Lean movements that´s increasingly the case. Nevertheless more could and should be done in many teams. Each and every developer should keep in mind that Production Efficiency is as important to the customer as Functionality and Quality - whether he/she states it or not. Making software development more efficient is important - but still sooner or later even agile projects are going to hit a glas ceiling. At least as long as they neglect the second SoI facet: Evolvability. Delivering correct high quality functionality in short cycles today is good. But not just any software structure will allow this to happen for an indefinite amount of time.[1] The less explicitly software was designed the sooner it´s going to get stuck. Big ball of mud, monolith, brownfield, legacy code, technical debt… there are many names for software structures that have lost the ability to evolve, to be easily changed to accomodate new requirements. An evolvable code base is the opposite of a brownfield. It´s code which can be easily understood (by developers with sufficient domain expertise) and then easily changed to accomodate new requirements. Ideally the costs of adding feature X to an evolvable code base is independent of when it is requested - or at least the costs should only increase linearly, not exponentially.[2] Clean Code, Agile Architecture, and even traditional Software Engineering are concerned with Evolvability. However, it seems no systematic way of achieving it has been layed out yet. TDD + SOLID help - but still… When I look at the design ability reality in teams I see much room for improvement. As stated previously, SoI - or to be more precise: Evolvability - can hardly be measured. Plus the customer rarely states an explicit expectation with regard to it. That´s why I think, special care must be taken to not neglect it. Postponing it to some large refactorings should not be an option. Rather Evolvability needs to be a core concern for every single developer day. This should not mean Evolvability is more important than any of the other requirement aspects. But neither is it less important. That´s why more effort needs to be invested into it, to bring it on par with the other aspects, which usually are much more in focus. In closing As you see, requirements are of quite different kinds. To not take that into account will make it harder to understand the customer, and to make economic decisions. Those sub-aspects of requirements are forces pulling in different directions. To improve performance might have an impact on Evolvability. To increase Production Efficiency might have an impact on security etc. No requirement aspect should go unchecked when deciding how to allocate resources. Balancing should be explicit. And it should be possible to trace back each decision to a requirement. Why is there a null-check on parameters at the start of the method? Why are there 5000 LOC in this method? Why are there interfaces on those classes? Why is this functionality running on the threadpool? Why is this function defined on that class? Why is this class depending on three other classes? These and a thousand more questions are not to mean anything should be different in a code base. But it´s important to know the reason behind all of these decisions. Because not knowing the reason possibly means waste and having decided suboptimally. And how do we ensure to balance all requirement aspects? That needs practices and transparency. Practices means doing things a certain way and not another, even though that might be possible. We´re dealing with dangerous tools here. Like a knife is a dangerous tool. Harm can be done if we use our tools in just any way at the whim of the moment. Over the centuries rules and practices have been established how to use knifes. You don´t put them in peoples´ legs just because you´re feeling like it. You hand over a knife with the handle towards the receiver. You might not even be allowed to cut round food like potatos or eggs with it. The same should be the case for dangerous tools like object-orientation, remote communication, threads etc. We need practices to use them in a way so requirements are balanced almost automatically. In addition, to be able to work on software as a team we need transparency. We need means to share our thoughts, to work jointly on mental models. So far our tools are focused on working with code. Testing frameworks, build servers, DI containers, intellisense, refactoring support… That´s all nice and well. I don´t want to miss any of that. But I think it´s not enough. We´re missing mental tools, tools for making thinking and talking about software (independently of code) easier. You might think, enough of such tools already exist like all those UML diagram types or Flow Charts. But then, isn´t it strange, hardly any team is using them to design software? Or is that just due to a lack of education? I don´t think so. It´s a matter value/weight ratio: the current mental tools are too heavy weight compared to the value they deliver. So my conclusion is, we need lightweight tools to really be able to balance requirements. Software development is complex. We need guidance not to forget important aspects. That´s like with flying an airplane. Pilots don´t just jump in and take off for their destination. Yes, there are times when they are “flying by the seats of their pants”, when they are just experts doing thing intuitively. But most of the time they are going through honed practices called checklist. See “The Checklist Manifesto” for very enlightening details on this. Maybe then I should say it like this: We need more checklists for the complex businss of software development.[3] But that´s what software development mostly is about: changing software over an unknown period of time. It needs to be corrected in order to finally provide promised operations. It needs to be enhanced to provide ever more operations and qualities. All this without knowing when it´s going to stop. Probably never - until “maintainability” hits a wall when the technical debt is too large, the brownfield too deep. Software development is not a sprint, is not a marathon, not even an ultra marathon. Because to all this there is a foreseeable end. Software development is like continuously and foreever running… ? And sometimes I dare to think that costs could even decrease over time. Think of it: With each feature a software becomes richer in functionality. So with each additional feature the chance of there being already functionality helping its implementation increases. That should lead to less costs of feature X if it´s requested later than sooner. X requested later could stand on the shoulders of previous features. Alas, reality seems to be far from this despite 20+ years of admonishing developers to think in terms of reusability.[1] ? Please don´t get me wrong: I don´t want to bog down the “art” of software development with heavyweight practices and heaps of rules to follow. The framework we need should be lightweight. It should not stand in the way of delivering value to the customer. It´s purpose is even to make that easier by helping us to focus and decreasing waste and rework. ?

  • Add an objective @property attribute in objective-c

    - by morticae
    Does anyone know of a way to add additional attribute types to the @property keyword without modifying the compiler? Or can anyone think of another way to genericize getter/setter creation? Basically, I have a lot of cases in a recent project where it's handy for objects to lazily instantiate their array properties. This is because we have "event" objects that can have a wide variety of collections as properties. Subclassing for particular events is undesirable because many properties are shared, and it would become a usability nightmare. For example, if I had an object with an array of songs, I'd write a getter like the following: - (NSMutableArray *)songs { if (!songs) { songs = [[NSMutableArray alloc] init]; } return songs; } Rather than writing dozens of these getters, it would be really nice to get the behavior via... @property (nonatomic, retain, lazyGetter) NSMutableArray *songs; Maybe some fancy tricks via #defines or something? Other ideas?

  • Strategy to lazy load images for buttons within UIScrollView?

    - by greypoint
    I have a horizontal UIScrollView that contains UIButtons (though it could be any object). I would like to only download images for these buttons as the user scrolls and they are seen. I would also like an activityindicator running on each button while the images are downloading. Here's what I've tried with results: Check content offset of uiscrollview and download images for visible buttons. Problem: issues getting activity view shown within subclassed UIButton and not desired usability since images are only downloaded once scrolling stops. Add subviews (not buttons) to the UIScrollview hoping to use the view's ViewController to initiate a downloaded on viewDidAppear. Problem: viewDidAppear never seems to get called (because I am using addSubView?). I've seen other apps that do this kind of loading but need some guidance on the typical set-up. Ebay's app is a great example. All items have a default image until the item comes into view, then an activityindicator runs and the items unique image is downloaded. Thanks for assistance.

  • UITextField valueDidChange-Event

    - by Infinite
    Is there a way to catch a "valueDidChange"-Event for a Textfield? oO I've got a modalView with an UITextField. When the UITextField is empty, the "Done"-Button in the NavigationBar should be disabled and when there is Text entered, it should become enabled. Right now the only way to accomplish this by using the "textFieldShouldReturn"-Method. This works but is simply horrible for usability. Isn't there a way to check the requirements every time a letter is being entered or removed?

  • Tree View WIKI replacement solution for SharePoint like Confluence?

    - by Melih Öztürk
    Hi to all, I keep my Process Documents on SVN and I want to create a Wiki page includes the information about these files. We use SharePoint in the company for basic document sharing and team sites. As it is mentioned in http://stackoverflow.com/questions/256407/what-are-your-biggest-complaints-about-sharepoint SharePoint Wiki lacks of usability. I need an easy to use wiki tool which is capable of showing the content like WikiPedia contents and it would be great if I could have the SharePoint tree view and Active Directory authentication also. I googled it and found Atlassian's Confluence and it seems that this product is capable of the requirements. We use Jira for issue tracking, so we can use it's reporting in dashboards. I need and it has a Wiki part which displays wiki pages in tree view. It should be like Does anyone used Confluence or have an idea for other products which meets my requirements

  • Errorprovider shows error on using windows close button(X)

    - by Pankaj Kumar
    Hi guys, Is there any way to turn the damned error provider off when i try to close the form using the windows close button(X). It fires the validation and the user has to fill all the fields before he can close the form..this will be a usability issue because many tend to close the form using the (X) button. i have placed a button for cancel with causes validation to false and it also fires a validation. i found someone saying that if you use Form.Close() function validations are run... how can i get past this annoying feature. i have a MDI sturucture and show the form using CreateExam.MdiParent = Me CreateExam.Show() on the mdi parent's menuitem click and have this as set validation Private Sub TextBox1_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBox1.Validating If String.IsNullOrEmpty(TextBox1.Text) Then Err.SetError(TextBox1, "required") e.Cancel = True End If If TextBox1.Text.Contains("'") Then Err.SetError(TextBox1, "Invalid Char") e.Cancel = True End If End Sub Any help is much appreciated. googling only showed results where users were having problem using a command button as close button and that too is causing problem in my case

  • Ideas for web development practical jokes?

    - by Ellie P.
    I am a web developer for a Django-based site for a student organization, and I have the opportunity to make the website temporarily absurd for a day of general campus-wide debauchery and chaos (long story, doesn't matter.) What are your best ideas for web development practical jokes (that you could never use in the real world)? For example, one idea we had was to use a client-side script to convert each character to its upside down equivalent in Unicode, si?? ??i? ?ui????os. I'm not necessarily looking for Django-specific solutions. I imagine most of these things would happen on the front-end. I am also quite aware that usability will suffer considerably--the point is to be fun for a day, and there will always be a link to the normal version of the site. Also, everything must be relatively cosmetic and easily reversible--I'm happy to swap out static CSS/JS/HTML/templates/images, and even temporarily add a django view, but no messing with the data level!

  • What makes good software good?

    - by Jonta
    People probably have a lot of different answers here, like good...: scalability, speed, usability, stability, consistency, completeness, absence of bugs, accessibility, documentation, code-quality and so on. There are a lot of philosophies on development of software. Like the UNIX-philosophy. Often vague and not easy to understand. I am looking for statements such as the one cited below. Which you can ask about the software when it's in the design-stage, is ready to be coded, and has been coded and is ready for launch. The software I am talking about, is of course the software made for the end-user. Ken Rockwell wrote: "I expect that it will let me get more accomplished in less time." (Here one could ask "will this let me get more accomplished in less time?")

  • Public and Internal members in an Internal class?

    - by Noldorin
    Ok, so this may be a bit of a silly question, and there's certainly the obvious answer, but I was curious if I've missed any subtleties here. Is there any difference in terms of visibility/usability between a public member declared in an internal class and an internal member declared in an internal class? i.e. between internal class Foo { public void Bar() { } } and internal class Foo { internal void Bar() { } } If you declared the method as public and also virtual, and then overrode it in a derived class that is public, the reason for using this modifier is clear. However, is this the only situation... am I missing something else?

(yes, I know this is not a very formal method) Now a new guy without experience are going to join our team. We think now is the momento to make a little list of things that all we should test in each form. Divided by categories. For example usability: Test that the taborder of each control are properly setted, or Valitacion: Test that the max lenght of each textbox match with the max lenght of a field in the DB...etc We don't one to Reinvent the Wheels, so I want to know if such kind of document already exists.

  • How to remember checkbox input in PHP Forms

    - by Derek
    For usability purposes I like to set up my form fields this way: <?php $username = $_POST['username']; $message = $_POST['message']; ?> <input type="text" name="username" value="<?php echo $username; ?>" /> <textarea name="message"><?php echo $message; ?></textarea> This way if the user fails validation, the form input he entered previously will still be there and there would be no need to start from scratch. My problem is I can't seem to keep check boxes selected with the option that the user had chosen before (when the page refreshes after validation fails). How to do this?
