INSTALLING APPLICATIONS Applications are distributed inside iOS’ .ipa packages. An .ipa package is a binary archive containing compiled ARM code, non-compiled resources such as images, and other informations about the application Every package should be digitally signed .ipa packages can only be installed via the proprietary iTunes application. Only packages signed by Apple can be installed APPLICATION ISOLATION Each application runs in its own Unix process with its own user ID Each installed application can access ﬁles only from the part of iOS’s ﬁle system that was created for it (sandbox) Operations that have security or privacy implications (e.g., accessing the GPS) must be explicitly authorized by the user THE APP SANDBOX Image from the iOS Developer Library Each iOS app operates within its own sandbox
THE PROBLEM How to save the state (of a UI, for instance) so that it survives even when the application is closed/ killed The state should be restored when the application is opened again: to the user it is as if the application has always been there We will consider a UI with an editable text ﬁeld, a checkbox, and a seekbar Solution: use the facilities provided by (and follow the rules dictated by) the platform’s frameworks ANDROID: ACTIVITIES AND APPLICATIONS UIs are managed inside activities An application may contain several activities Activities are independent by a large extent, but they share some resources associated with the application (e.g., the user ID) An activity may be destroyed by the OS while the application that hosts it survives. Later on, a new instance of the same activity may be created ANDROID: INSTANCE STATE If an activity is destroyed and recreated by the OS (e.g., because the screen is rotated): the new activity is a new instance of the old one...

In the first PowerPoint tutorial you learned how to create and save a new presentation (the Screenbeans slide show). You saw a sample slide show (The Tudor Monarchs). You learned how to prepare an outline, you typed text for each slide, added clip art, and set timings. You added an effect to enhance the slide transition, you selected a color scheme, and may have even created a new background effect. You changed the printer settings so that you can print out handouts rather than just individual slides of your shows. For many classrooms and for most K-12 students, what you learned in chapter 9 is just fine; it’s all you need to know. But, if you're ready to take the next step and learn some more advanced skills with PowerPoint, or if you teach computer-savvy students who want more challenging skills to master, this chapter's for you. Most PowerPoint presentations you see in school or at work are what are called linear presentations. That is, each slide is designed to proceed one slide right after another. The first slide transitions to the second, which transitions to the third, and so forth. For many educational tasks, this is fine. But, what if... What if you want your students to create an interactive story, where, for example, younger kids could read on Slide One a story about a dragon, then choose, on Slide Two, any one of three possible places that the dragon could go? By clicking on the word "desert," the show would move to a slide describing what happens to the dragon in the desert. If the student clicks on the word "forest," a different slide sequence appears with another ending. The learner thus participates, not by simply clicking on slide after slide in one, linear direction, but by making choices that affect what slide comes next, thus making the presentation interactive and non-linear.

This manual is divided in two parts; part 1 describing how to use the programming tool Pluto Manager and part 2 describing the language rules. Part 1 begins with the chapter “Making your first program” which leads you through the creation of a simple example. For first time users this can be a good way to get started. The programming language is related to the programming standard IEC 61131-3. The programming can also be done in text form with a standard text editor. Before downloading to the system the code must be compiled to hex-format. Download of the hex-file to a PLUTO-unit and monitoring is possible by either Pluto Manager or a standard terminal program as Hyper Terminal. Note that logic faults, like for example an emergency stop that controls the wrong output, cannot be detected by this software tool. Programs must therefore be reviewed and the safety applications carefully tested before being used in applications. Installation of Pluto Manager is performed by executing the self extracting EXE-file (InstallPlutoManager… .exe) without any parameters. This leads the user through the installation allowing the user to select the appropriate location. To run the program a registration code is required. However it is possible to use it without code in DEMO mode where compilation and online functions are disabled. To run in full version, the program requires a registration code. The code can be entered at start of the program.
This user guide is intended for a customer who has received a CLICK Loader File from an OEM and needs to write the CLICK project to their CLICK PLC using the CLICK Project Loader tool. Writing the CLICK project to your PLC is a very simple process and this document will walk you through the required steps. Note: The file extension of the CLICK Loader File is 'ckl'. This is different from the CLICK Project File, where the file extension is 'ckp'. The CLICK Project Loader only works with the CLICK Loader Files. What is CLICK Project Loader? The CLICK Project Loader is a tool provided with the free CLICK Programming Software (V1.11 or newer). The CLICK Project Loader was developed to provide a simple way for you to write a CLICK Project, provided by an OEM, to your PLC. When an OEM develops a CLICK Project for you, this Project may be password protected to protect the confidentiality of processes and information included in the Project. It is also common to have future modifications to this project that will be provided to you by the OEM. When these Project updates are provided to the customer only authorized personnel with the password information are able to write the file to the PLC. With the CLICK Project Loader, an OEM can modify a password-protected CLICK Project and export the Project as a CLICK Loader File. The OEM can then send the CLICK Loader File to you. You can use the CLICK Project Loader tool to write the password-protected CLICK Project into your CLICK PLC. The CLICK Project Loader will verify that the password of the new Project matches the password of the existing Project in the PLC. The CLICK Project Loader will ONLY write the new Project if the passwords MATCH.
Use of Design Patterns in PHP-Based Web Application Frameworks Andris Paikens, Guntis Arnicans Department of Computing University of Latvia RaiƼa blvd 19, RƯga, Latvia LV-1586 Andris.Paikens@di.lv, Guntis.Arnicans@lu.lv Abstract. It is known that design patterns of object-oriented programming are used in the design of Web applications, but there is no sufficient information which data patterns are used, how often they are used, and the level of quality at which they are used. This paper describes the results concerning the use of design patterns in projects which develop PHP-based Web application frameworks. Documentation and source code were analysed for 10 frameworks, finding that design patterns are used in the development of Web applications, but not too much and without much consistency. The results and conclusions can be of use when planning and developing new projects because the existing experience can be taken into account. The paper also offers information which design patterns are not used because they may be artificial or hard-to-use in real projects. Alternatively, developers may simply lack information on the existence of the design patterns.
