Web App - Scrolling long lists - 1 views

  • Scrolling Long Lists Another big problem with iPhone web apps is presenting very long lists efficiently. Digg has this problem with their stories and comments and they work around it by breaking stories into pages of ten and omitting all but the top five comments. Apple solves this problem nicely in their Mail app by loading 25 messages at a time and putting a link to get more at the end. Clicking it loads those messages and appends them to the end of the list, allowing you to use the joyous flick gesture to scroll the complete list at once. In my view, this is nicer than breaking the list up into separate pages. iUI makes it easy for you to use this convention in your own web apps. Simply create a link with target="_replace" and iUI will load the URL it and replace the <a> with the contents of the URL. Again, the URL should not point to a complete HTML document, but only the fragment you want to replace the "Get More" link with. For an example of incrementally loaded lists, look at the Digg demo again. Scroll to the bottom of the stories list and click on the "Get 10 More Stories..." link.

    Excellent find! I also think that "get more" is a more elegant solution. Where any information exceeds a single screen in any apps CeL develops, this should be the way to go.

  • In mobile browsers, you need to be especially careful about using timers because of the battery consumption. If you need to use many high-frequency timers at the same time, try to manage them using only one timer that will launch different behaviors from the same process.
  • The first question we need to ask ourselves is, what happens when our web page goes to the background because the user switches focus to another application (in multitasking operating systems) or opens or browses to another tab or window? Another problem is what happens when the phone goes to sleep (because of the user’s inactivity while the script is executing). The behavior of timers can be a little tricky in these situations.Yet another problem is that timers execute on the same thread as the main script. If our script is taking too much processor time (a normal situation with large scripts on low- and mid-end devices), our timers will be delayed until some spare execution time is found.If we use a low frequency for the timer (for example, 10 milliseconds), the timer will generally have problems meeting the timetable.Remember that the JavaScript execution time depends a lot on the device hardware and the browser’s engine. Even if they’re running the same operating system, like Android, execution times can differ: for example, an HTC G1 will be much slower than a Nexus One with a 1-Ghz processor.
  • As shown in Figure 4, the real times are very different on different devices. On low- and mid-end devices, if they work at all, the result is far from our 200 ms intention—some low-end devices don’t even accept timers with a frequency of less than 1 second.

The conclusions are: for low-frequency timers (1 second or more), there are no performance issues, and you can add as many as you want; for high-frequency timers (for example, 100 ms), though, every new timer created makes the UI more sluggish. The preferred solution is to use only one high-frequency timer.

    A very interesting journal essay that points out how info overload is not a new problem, but one that has existed ever since the first books. The writer examines how people in the previous centuries used the then-new technology of printing to help them handle the "plague of books" that was overwhelming their libraries. He then reminds us, that at the core of it all, it is not the technology itself that enables and empowers learning, but an ecology of human-tech interaction that helps us learn more effectively in today's Toffler-esque world. A fascinating read indeed. A more readable PDF version: http://www.iasc-culture.org/THR/archives/Spring2012/Wellmon_lo.pdf

  • How To Pick A Successful IdeaDon’t put everything behind your first idea! You wouldn’t go to the racetrack and put your life savings on 1/3000 odds, would you? Even though we are taught that all innovations come from a visionary who predicted a need for the future, this is usually not the case. Naturally, most inventions come from necessity and others from creative spark. When executing a creative idea with the resources you have available, you will have to make adjustments along the way that may not have been accounted for originally. Johansson suggests that you take the smallest executable step (smallest bet) so you don’t risk everything on your original idea.Once you define the smallest step, you know your scope of risk. This is very important because you can then take baby steps to overcome challenges and utilize resources more efficiently on your road to success (see image below). While strategy is paramount, one shouldn’t get lost in planning and take too long to execute. Stay motivated to move forward, because forward motion even through failure is the key to success.

  • Making ideas happen isn’t easy and requires patience, determination and hard work. The most important part of it is not just coming up with a promising concept, but rather rethinking it over and over again, implementing it and then putting it to practice.Most inventions come from necessity, so pay attention to small problems in your environment and find simple solutions to these problems. Do not sit idle on the idea — act instead. Take opposing thoughts and resolve them in your innovative designs. And keep innovating all the time, one step at a time. The time will pass, and if you have some luck, you will see your idea growing, flourishing and maybe even turning into a real success. …So what are you waiting for?

  • If you have ever entertained that seemingly laughable thought of installing anti-virus software on your mobile phone, you are not alone.
  • A few months ago, Kaspersky Labs discovered two Trojan-SMS malware that masqueraded as media player apps for Android devices. Once installed, the malware can send premium SMSes costing US$6 ($7.70) each without the user's knowledge.

  • ...4 more annotations...
  • According to Kaspersky, closed platforms (iPhone, BlackBerry and the old Symbian) are more secure while open platforms (Android, Windows Mobile 6 Series and the new Symbian) are less so. This, Kaspersky explains, is because the level of security is inversely proportionate to the ease with which developers can build apps on it.
  • "The more secure a system is, the harder it is for development - both for the good guys and the bad guys," he said.
  • security and ease of app development are two sides of the same coin that have to be finely balanced in order for a mobile platform to succeed.
  • iPhone users face exactly the same problems, but unfortunately, Apple has a very strict regulation on the apps industry, and the SDK it gives to software companies doesn't let us develop what we need. (Thanks to Apple's efforts policing the platform) iPhone users face maybe fewer virus problems, but the threat with confidential data is still there - and it only takes one threat. Android may face more viruses, but at the same time, there will also be more solutions from us and our competitors
  • bernard tan on 11 Nov 10
     
    Open source and Closed source mobile platform faces security issue. An open source platform may be more prone to malwares and viruses. Some factors we should consider in our context here in education to protecting confidential contents and issues while considering developing apps. for example we could risk all of our contacts information being stolen and end up being sold to some advertising spamming companies who spam you daily or watches your daily activities.
  • bernard tan on 11 Nov 10
     
    I used to think open source platform was very good for development but now you can have different view if you think like a hacker. It will take at least a year or more before mobile security catch up.

  • Leaving purely technical considerations aside (in some cases the final result is better than in others), the general quality of those magazines is without doubt extremely high and the integration between classic and multimedia content makes their reading experience very pleasant and engaging. But there is a basic limitation that could play a significant role in preventing their widespread diffusion, thereby making them not competitive in terms of economic return. The problem is not the limited number of iPads in circulation, as some may think, but the difficulty – or the inability – to download single issues of a certain magazines on your device because of their excessive size, which usually is around 400 MB.

Apart from the frustration generated by waiting too long for the completion of the download (especially if you consider that there are an infinite number of alternative sources of information available in a few seconds, for free, just surfing the web), when the user doesn’t have access to a wi-fi network, he is likely to quit the purchase altogether

  • This limit, which negatively affects sales volumes and profitability of editorial projects aimed at iPad users, will bring developers to rethink radically the structure of such contents and limit their size. Otherwise, a significant proportion of those users who have once experienced the frustration of the download will not want to repeat the purchase a second time.

    Something it's not about how rich or engaging the contents are but how the ease of being able to reach for it is. ( infrastructure) Afterall would you bother buying a magazine from your local newsagent if you had to stand there and wait in a queue for 30 minutes or more.

  • So why, then, would it be better to work with a 16-bit image? One word - flexibility. When you're editing an image in Photoshop, sooner or later, if you continue making edits, you're going to run into problems. The most common problem is what's known as "banding", where you've lost so much detail in the image that Photoshop can no longer display smooth transitions from one color to the next. Instead, you get an ugly stair-stepping effect between colors and tonal values.

    I llike my friend's summary: "The way we think affects the way we learn. If we think we passed a test because we're "smart", then we don't work so hard and learn less. If we think we passed a test because we "worked hard", then we work harder and learn more. And if we think making mistakes helps us learn (instead of making us look stupid), then we tend to learn more." I think this is one major reason why children can learn and master tough games so fast, but take forever to solve a Maths test problem.

  • So can computers actually help improve our concentration and contemplation, instead of leading us into distraction? The problem, as Pang puts it, is that "Technologies that were supposed to help us think better, work more efficiently, and connect more meaningfully with others now interrupt us, divide our attention, and stretch us thin."
  • In the paper he outlines give principles of contemplative computing; Build awareness through DIY and self-experimentation Recognize that we are cyborgs, and humans Create rewarding challenges Support mind-wandering Treat flow as a means, not an end
  • Pang suggests that we don't have to choose between information technology and contemplation, and suggests contemplative computing as a new way forward. He describes contemplative computing as something you do, not a product. But the principles of contemplative computing could be extending to application design. "The problem is that today's information technologies are often poorly-designed and thoughtlessly used: they're like unreliable prosthetics that we have to depend on, but can't quite control or trust," Pang says.

  • You might be surprised to see "support mind wandering" on the list. But Pang makes a distinction between mind wandering and distraction, and points out the value creative value of mind wandering and day dreaming (for more on this subject, check out this article by Jonah Lehrer, though Lehrer doesn't really make the distinction between distraction and mind wandering).

    Students can easily download a document from Edmodo, use it in another app (like a PDF annotation app) and then upload it again onto Edmodo to submit it as an 'assignment'. This solves the whole 'work-flow' problem that many teachers faced upon the introduction of iPads into the classroom. Worksheets, handouts, task sheets, graphic organizers, anything you want the students to work on, just upload it into your library, add it to a folder that you share with the students or attach it to a post, then they access it and open it in another app. Once they have finished, they need to upload it into their 'backpacks' and then submit it as an attachment to an 'assignment' that you posted.

  • What new opportunities do you see for apps in the developing world? Nobody focuses on the problem of creating apps for somebody whose monthly income is $200. Those people are not part of the computer age or the Internet age; most of them are not literate. So we run app competitions in India to try to get people thinking from that perspective. The winner of our last competition was a group of students who designed a commerce app for “fruit walas,” the guys who run around with carts selling fruits and vegetables. These students created a graphically intuitive way of running a small vegetable business. There are something like five million fruit walas in India, so if you had an app for them, there could be a lot of money to be made.

There are other eportfolio iphone apps that do the creating of mobile eportfolios, such as Curtin University's iphone app. However, the problem is that those apps are specific to their eportfolio systems, so they are generally closed to non-university users. If I find one that is open (and uses open systems), I'll share here ASAP.
