• Manage ClickOnce releases for different parties

  - by Dirk Beckmann

  I'm struggling with release management of a piece of software. First some general information: It is a ClickOnce application I follow the release often practice There are about 30 parties served with this software I need full control which update will be delivered to which party Not each party is allowed to get the latest update/release Each party has multiple clients that are all allowed to get the latest update, served for the specific party So that's what my requirements are in a rough description. So let me explain what I was thinking about how to solve this. I would like to create a "deployment" website (asp.net) that will handle all the requests There are two endpoints one for download the client and one where the client checks for updates So each party has a separate endpoint like DeploymentSite/party1 and another for DeploymentSite/party2 The Application Files should still be stored centralized So I thought it would be manageable with mage.exe with the following steps Build application and store new release into Application Files Repository/Folder Get parties that should be updated (config file, database what ever) Run mage.exe to create a new application and deployment manifest for each party in the update list with new Application File Location (1.0.2) Actually I'm really struggling with this mage.exe staff. I can't create the appropriate files with the needed codebase. How to handle thes requirements?

• Git branching and tagging best practices

  - by Code-Guru

  I am currently learning to use Git by reading Pro Git. Right now I'm learning about branching and tags. My question is when should I use a branch and when should I use a tag? For example, say I create a branch for version 1.1 of a project. When I finish and release this version, should I leave the branch to mark the release version? Or should I add a tag? If I add a tag, should I delete the version branch (assuming that it is merged into master or some other branch)?

• Opinion on LastPass's security for the Average Joe [closed]

  - by Rook

  This is borderline on objective/subjective, but I'm posting it here since I'm more interested in objective facts, without going into too much technical details, than I am in user reviews of LastPass. I've always used offline ways for (password / sensitive data) storage, but lately I keep hearing good things about LastPass. Indeed, it is more practical having it always accessible from every computer you're using without syncing and related problems, but the security aspect still troubles me. How (in a nutshell for dummies) does LastPass keep your data secure / can their employees see your data, and what is your opinion for such storage of more than usual keeping of sensitive data (bank PIN codes, some financial / business related stuff and so on - you know, the things that would practically hurt if lost / phished)? What are your opinions of it, and do you trust it for such? Any bad experiences? If someone for example is sniffing your wifi network, would such data be easier than usual to sniff out?

• A list of pros and cons to giving developers “Local Admin” privileges to their machines? [closed]

  - by Boden

  Possible Duplicate: Is local “User” rights enough or do developers need Local Administrator or Power User while coding? I currently work for a large utilities company which currently does not grant “Local Admin” access to developers. This is causing a lot of grief as anything that requires elevated privileges needs to be done by the Desktop Support/Server Teams. In some cases this can take several days and requires our developers to have to show why they need this access. I personally think that all developers should have local administration rights and are currently fighting with management to achieve this but I would like to know what other people think about this. To achieve this I would like to hear what people believe are the pros and cons of letting developers have local admin access to their machines. Here are some I have come up with: Pros Loss time is keep low as developers can resolve issues that would normally require Local Admin Evaluation of tools and software are possible to improve productivity Desktop support time not wasted installing services and software on developers PC Cons Developers install software on local PC that could be malicious to others or inappropriate in a business environment Desktop Support required to support a PC that is not the norm Development done with admin access that then fails when promoted to another environment that does not have the same access level

• Is there any evidence that one of the current alternate JVM languages might catch on?

  - by FarmBoy

  There's been a lot of enthusiasm about JRuby, Jython, Groovy, and now Scala and Clojure as the language to be the successor to Java on the JVM. But currently only Groovy and Scala are in the TIOBE top 100, and none are in the top 50. Is there any reason to think that any of this bunch will ever gain significant adoption? My question is not primarily about TIOBE, but about any evidence that you might see that could indicate that one of these languages could get significant backing that goes beyond the enthusiasts.

• Declarative programming vs. Imperative programming

  - by EpsilonVector

  I feel very comfortable with Imperative programming. I never have trouble expressing algorithmically what I want the computer to do once I figured out what is it that I want it to do. But when it comes to languages like SQL or Relational Algebra I often get stuck because my head is too used to Imperative programming. For example, suppose you have the relations band(bandName, bandCountry), venue(venueName, venueCountry), plays(bandName, venueName), and I want to write a query that says: all venueNames such that for every bandCountry there's a band from that country that plays in venue of that name. In my mind I immediately go "for each venueName iterate over all the bandCountries and for each bandCountry get the list of bands that come from it. If none of them play in venueName, go to next venueName. Else, at the end of the bandCountries iteration add venueName to the set of good venueNames". ...but you can't talk like that in SQL and I actually need to think about how to formulate this, with the intuitive Imperative solution constantly nagging in the back of my head. Did anybody else had this problem? How did you overcome this? Did you figured out a paradigm shift? Made a map from Imperative concepts to SQL concepts to translate Imperative solutions into Declarative ones? Read a good book? PS I'm not looking for a solution to the above query, I did solve it.

• What language should I use for making a cross platform library?

  - by Andrei

  I want to build a SyncML parsing library (no UI) which should be able to build up messages based on information provided by the host application, fed in by the library's methods. Also, the library should to be able to do callbacks to methods in the host application. I want to be able to compile this and have it available on as many platforms as possible: Windows, Windows Phone 7 OS, OSX, iOS, Linux, Android, BlackBerry. Basically as many platforms as possible. The priority is to have this available on mobile devices. Questions: What setup should I use? (programming languages, compilers, IDE etc.) How would I compile this library for these different platforms and how would I connect to it? Any other info? e.g. articles that cover the subject of cross-platform development? I haven't done this sort of a cross-platform project before, so any available information to put me in the right direction would be welcomed. Myself, I have a background in C#/.NET and Objective-C.

• Meta-licensing of applications

  - by Gene

  I'm currently evaluating license management solutions for our customized and project-based applications, which are supported by a single server in the intranet of the customer. The applications use common functionality provided by the server (session handling, data synchronization, management capabilities, etc) and are installed on mobile devices. We allow our customers to run the applications on X devices and want to check on the server, whether the customer sticks to this limit (based on the sessions). We don't want licensing software to be installed on the devices itself (for example providing X serials to the customer) nor do we want to host an additional server for licensing in the intranet of the customer. If a client connects, our server should load the license for the application running on the client and verify, that there are sessions left. The licensing managers I looked at (12 products so far) focus on the application itself and don't allow me to implement such a floating behavior as described above. For example, this software could easily be used to create a "Standard Edition" or a "Professional Edition" of our server software, which is not our intention. In XHEO DeployLX there is a "Session Limit", which allows to limit the license to the currently established sessions in ASP.NET, which comes very close to my needs. I'm currently thinking of implementing a custom solution, which allows me to load and enforce custom-defined licenses per application on the server-side and a simple editor to define such licenses (which would contain a type and the limit itself), but I would appreciate an existing, easy to integrate commercial solution. I think it could be possible to use DeployLX for this task, but I would spend a lot of money for implementing most of the solution myself (except for the editor). Thanks in advance for any suggestions or hints. Gene

• Where to go after Adobe Flex? [closed]

  - by jan halfar

  After this post http://blogs.adobe.com/flex/2011/11/your-questions-about-flex.html and especially this paragraph: ... Does Adobe recommend we use Flex or HTML5 for our enterprise application development? In the long-term, we believe HTML5 will be the best technology for enterprise application development. We also know that, currently, Flex has clear benefits for large-scale client projects typically associated with desktop application profiles. ... Make no mistake, the days of Flex are over. Thus a lot of people are asking themselves: Which technology(ies) will solve their and their customers problems in a future without flex? P.S.: Obviously the correct answer for adobe would have been " ...Since we believe, that HTML5 will be the best technology enterprise application development, we will ensure that it will be targeted by future releases of the Flex framework ..."

• Best way to throw exception and avoid code duplication

  - by JF Dion

  I am currently writing code and want to make sure all the params that get passed to a function/method are valid. Since I am writing in PHP I don't have access to all the facilities of other languages like C, C++ or Java to check for parameters values and types public function inscriptionExists($sectionId, $userId) // PHP vs. public boolean inscriptionExists(int sectionId, int userId) // Java So I have to rely on exceptions if I want to make sure that my params are both integers. Since I have a lot of places where I need to check for param validity, what would be the best way to create a validation/exception machine and avoid code duplication? I was thinking on a static factory (since I don't want to pass it to all of my classes) with a signature like: public static function factory ($value, $valueType, $exceptionType = 'InvalidArgumentException'); Which would then call the right sub process to validate based on the type. Am I on the right way, or am I going completely off the road and overthinking my problem?

• How do I deal with analysis paralysis?

  - by Anne Nonimus

  Very frequently, I am stuck when choosing the best design decision. Even for small details, such as function definitions, control flow, and variable names, I spend unusually long periods perusing the benefits and trade-offs of my choices. I feel like I am losing a lot of efficiency by spending my hours on insignificant details like these. Even though, I know in the back of my mind that I can change these things if my current design doesn't work out, I have trouble deciding firmly on one choice. What should I do to combat this problem?

• Advice on learning programming languages and math.

  - by Joris Ooms

  I feel like I'm getting stuck lately when it comes to learning about programming-related things; I thought I'd ask a question here and write it all down in the hope to get some pointers/advice from people. Perhaps writing it down helps me put things in perspective for myself aswell. I study Interactive Multimedia Design. This course is based on two things: graphic design on one hand, and web development on the other hand. I have quite a decent knowledge of web-related languages (the usual HTML/JS/PHP) and I'll be getting a course on ASP.NET next year. In my free time, I have learnt how to work with CodeIgniter, aswell as some diving into Ruby (and Rails) and basic iOS programming. In my first year of college I also did a class on Java (19/20 on the end result). This grade doesn't really mean anything though; I have the basics of OOP down but Java-wise, we learnt next to nothing. Considering the time I have been programming in, for example, PHP.. I can't say I'm bad at it. I'm definitely not good or great at it, but I'm decent. My teachers tell me I have the programming thing down. They just tell me I should keep on learning. So that's what I do, and I try to take in as much as possible; however, sometimes I'm unsure where to start and I have this tendency to always doubt myself. Now, for the 'question'. I want to get into iOS programming. I know iOS programming boils down to programming in Cocoa Touch and Objective-C. I also know Obj-C is a superset of C. I have done a class on C a couple of years ago, but I failed miserably. I got stuck at pointers and never really understood them.. Until like a month ago. I suddenly 'got' it. I have been working through a book on Objective-C for a week or so now, and I understand the basics (I'm at like.. chapter 6 or so). However, I keep running into similar problems as the ones I had when I did the C class: I suck at math. No, really. I come from a Latin-Modern Languages background in high school and I had nearly no math classes back then. I wanted to study Computer Science, but I failed there because of the miserable state of my mathematics knowledge. I can't explain why I'm suddenly talking about math here though, because it isn't directly related to programming.. yet it is. For example, the examples in the book I'm reading now are about programming a fraction-calculator. All good, I can do the programming when I get the formulas down.. but it takes me a full day or more to actually get to that point. I also find it hard to come up with ideas for myself. I made one small iOS app the other day and it's just a button / label kind of thing. When I press the button, it generates a random number. That's really all I could come up with. Can you 'learn' that? It probably comes down to creativity, but evidently, I'm not too great at being creative. Are there any sites or resources out there that provide something like a basic list of things you can program when you're just starting out? Maybe I'm focusing on too many things at once. I want to keep my HTML/CSS at a decent level, while learning PHP and CodeIgniter, while diving into Ruby on Rails and learning Objective-C and the iOS SDK at the same time. I just want to be good at something, I guess. The problem is that I can't seem to be happy with my PHP stuff. I want more, something 'harder'; that's why I decided to pick up the iOS thing. Like I said, I have the basics down of a lot of different languages. I can program something simple in Java, in C, in Objective-C as of this week.. but it ends there. Mostly because I can't come up with ideas for more complex applications, and also because I just doubt myself: 'Oh, that's too complex, I can never do that'. And then it ends there. To conclude my rant, let me basically rephrase my questions into a 'tl;dr' part. A. I want to get into iOS programming and I have basic knowledge of C/Objective-C. However, I struggle to come up with ideas of my own and implement them and I also suck at math which is something that isn't directly related to, yet often needed while programming. What can I do? B. I have an interest in a lot of different programming languages and I can't stop reading/learning. However, I don't feel like I'm good in anything. Should I perhaps focus on just one language for a year or longer, or keep taking it all in at the same time and hope I'll finally get them all down? C. Are there any resources out there that provide basic ideas of things I can program? I'm thinking about 'simple' command-line applications here to help me while studying C/Obj-C away from the whole iPhone SDK. Like I said, the examples in my book are mainly math-based (fraction calculator) and it's kinda hard. :( Thanks a lot for reading my post. I didn't plan it to be this long but oh well. Thanks in advance for any answers.

• Quality Assurance & Quality Control = verification & validation?

  - by user970696

  According to a book (page below), reviewing e.g. design (verification activity) is quality assurance. I would not agree, I would say its quality control because we are checking the conformance to specification, plans and detecting deviations (defects) as we do in quality control. But what would be an example of QA then? Could you give me a clear example that proves/disproves what is this book saying? Software Testing: Srinisvasan Desikan, Gopalaswamy Ramesh

• Why doesn't Gradle include transitive dependencies in compile / runtime classpath?

  - by Francis Toth

  I'm learning how Gradle works, and I can't understand how it resolves a project transitive dependencies. For now, I have two projects : projectA : which has a couple of dependencies on external libraries projectB : which has only one dependency on projectA No matter how I try, when I build projectB, gradle doesn't include any projectA dependencies (X and Y) in projectB's compile or runtime classpath. I've only managed to make it work by including projectA's dependencies in projectB's build script, which, in my opinion does not make any sense. These dependencies should be automatically attached to projectB. I'm pretty sure I'm missing something but I can't figure out what. I've read about "lib dependencies", but it seems to apply only to local projects like described here, not on external dependencies. Here is the build.gradle I use in the root project (the one that contains both projectA and projectB) : buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.3' } } subprojects { apply plugin: 'java' apply plugin: 'idea' group = 'com.company' repositories { mavenCentral() add(new org.apache.ivy.plugins.resolver.SshResolver()) { name = 'customRepo' addIvyPattern "ssh://.../repository/[organization]/[module]/[revision]/[module].xml" addArtifactPattern "ssh://.../[organization]/[module]/[revision]/[module](-[classifier]).[ext]" } } sourceSets { main { java { srcDir 'src/' } } } idea.module { downloadSources = true } // task that create sources jar task sourceJar(type: Jar) { from sourceSets.main.java classifier 'sources' } // Publishing configuration uploadArchives { repositories { add project.repositories.customRepo } } artifacts { archives(sourceJar) { name "$name-sources" type 'source' builtBy sourceJar } } } This one concerns projectA only : version = '1.0' dependencies { compile 'com.company:X:1.0' compile 'com.company:B:1.0' } And this is the one used by projectB : version = '1.0' dependencies { compile ('com.company:projectA:1.0') { transitive = true } } Thank you in advance for any help, and please, apologize me for my bad English.

• Feasibility to take over a JavaMe Project by Coders who have no experience in JavaMe

  - by Stephenmjm

  As the original JavaMe team will leave to do other items. The JavaMe project will be taken over by some guys knowing nothing about JavaMe. Transition period: One month About this JavaMe project: about 3.5 million lines of code (more than 180 java file, SourceCode is 8.5KB in total) using the Polish, Proguard document: The JavaMe project itself have no document. No UML map. Difficulties I guess: familiar with the JavaMe, this should be okay In order to do the further development. We need to Read the sourceCode ---- It's not easy to read 3.5 million lines of code having not enough comment Adaptation work for more than 100 phone These are the questions, thank you! In the case of our guys have no experience in JavaMe, Is one month too hasty? In order to take the job in time . What we should ask the original JavaMe team to do . Considering we hava no experience in JavaMe. The complication we taking the Adaptation work without the original JavaMe team? Any other suggestions?

• What, if anything, to do about bow-shaped burndowns?

  - by Karl Bielefeldt

  I've started to notice a recurring pattern to our team's burndown charts, which I call a "bowstring" pattern. The ideal line is the "string" and the actual line starts out relatively flat, then curves down to meet the target like a bow. My theory on why they look like this is that toward the beginning of the story, we are doing a lot of debugging or exploratory work that is difficult to estimate remaining work for. Sometimes it even goes up a little as we discover a task is more difficult once we get into it. Then we get into implementation and test which is more predictable, hence the curving down graph. Note I'm not talking about a big scale like BDUF, just the natural short-term constraint that you have to find the bug before you can fix it, coupled with the fact that stories are most likely to start toward the beginning of a two-week iteration. Is this a common occurrence among scrum teams? Do people see it as a problem? If so, what is the root cause and some techniques to deal with it?

• Large invoice database structure and rendering

  - by user132624

  Our client has a MS SQL database that has 1 million customer invoice records in it. Using the database, our client wants its customers to be able to log into a frontend web site and then be able to view, modify and download their company’s invoices. Given the size of the database and the large number of customers who may log into the web site at any time, we are concerned about data base engine performance and web page invoice rendering performance. The 1 million invoice database is for just 90 days sales, so we will remove invoices over 90 days old from the database. Most of the invoices have multiple line items. We can easily convert our invoices into various data formats so for example it is easy for us to convert to and from SQL to XML with related schema and XSLT. Any data conversion would be done on another server so as not to burden the web interface server. We have tentatively decided to run the web site on a .NET Framework IIS web server using MS SQL on MS Azure. How would you suggest we structure our database for best performance? For example, should we put all the invoices of all customers located within the same 5 digit or 6 digit zip codes into the same table? Or could we set up a separate home directory for each customer on IIS and place each customer’s invoices in each customer’s home directory in XML format? And secondly what would you suggest would be the best method to render customer invoices on a web page and allow customers to modify for best performance? The ADO.net XML Data Set looks intriguing to us as a method, but we have never used it.

• Recommendation for a platform to teach game development to kids [closed]

  - by Moshe Kravchik

  My 11 years old son decided he want to create a Web game. He does not know much about programming and I never did any game development so I'm not the best teacher of the topic. On one hand I really want him to get into building things and doing his own game sounds perfect. So I'd like to find a way to keep him interested and progressing by himself. This means that I'm looking for a platform that is: 1. Simple for understanding and use, intuitive interface 2. Powerful 3. Good tools, preferrably free 4. Significant community for questions and tips 5. Localization - my son's English is quite poor (native Hebrew). We looked at Alice, but it was too limited in its abilities and isn't really a Web game building platform. HTML/CSS and Javascript - too low level for a kid to keep the interest. What would you recommend?

• Should I include HTML markup in my JSON response?

  - by Mike M. Lin

  In an e-commerce site, when adding an item to a cart, I'd like to show a popup window with the options you can choose. Imagine you're ordering an iPod Shuffle and now you have to choose the color and text to engrave. I'd like the window to be modal, so I'm using a lightbox populated by an Ajax call. Now I have two options: Option 1: Send only the data, and generate the HTML markup using JavaScript What's nice about this is that it trims down the Ajax request to the bear minimum and doesn't mix the data with the markup. What's not so great about this is that now I need to use JavaScript to do my rendering, instead of having a template engine on the server-side do it. I might be able to clean up the approach a bit by using a client-side templating solution. Option 2: Send the HTML markup What's good about this is that I can have the same server-side templating engine I'm using for the rest of my rendering tasks (Django), do the rendering of the lightbox. JavaScript is only used to insert the HTML fragment into the page. So it clearly leaves the rendering to the rendering engine. Makes sense to me. But I don't feel comfortable mixing data and markup in an Ajax call for some reason. I'm not sure what makes me feel uneasy about it. I mean, it's the same way every web page is served up -- data plus markup -- right?

• GCC 4.2.1 Compiling on Cygwin(Win7 64bit) for iPhone [closed]

  - by Kenneth Noland

  Hey This is going to take a long while to explain, but the short version is that I am currently attempting to compile the LLVM GCC frontend for ARMv7 to compile apps for the Cortex-A8(iPhone 3GS). I'm running into an error from LD when compiling libgcc(part of the gcc compilation process) that has been driving me mad! The command is this: /usr/llvm-gcc-4.2-2.8.source/build/./gcc/xgcc \ -B/usr/llvm-gcc-4.2_2.8.source/build/./gcc \ -B/usr/local/arm-apple-darwin/bin \ -B/usr/local/arm-apple-darwin/lib \ -isystem /usr/local/arm-apple-darwin/include \ -isystem /usr/local/arm-apple-darwin/sys-include \ -O2 -g -W -Wall -Wwrite-strings -wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -fno-inline -dynamiclib -nodefaultlibs -W1,-dead_strip \ -marm \ -install_name /usr/local/arm-apple-darwin/lib/libgcc_s.1.dylib \ -single_module -o ./libgcc_s.1.dylib.tmp \ -W1,-exported_symbols_list,libgcc/./libgcc.map -compatibility_version 1 -current_version 1.0 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc \ ... long list of .o files ... \ -lc And the result is typically a lot of undefined references to malloc, free, exit, etc. which typically indicate that libc is not getting compiled in. After going through the list of errors that ld is throwing, I see at the top that it is attempting to pull in /usr/lib/libc.a and complains that it is not the correct platform. Okay, that makes sense, so I spent 5 minutes on google and found an answer. Turns out that if I copy the libSystem.dylib and rename it to libc.dylib, that should solve the problem, but it doesn't. I couldn't find a copy of that file on my phone, so I pulled it directly from the SDK. I then get this strange error: ld64: in /usr/local/arm-apple-darwin/lib/libc.dylib, can't re-map file, errno=22 At this point, I did everything I could think of. I grabbed a fresh copy of my /usr/lib folder from my iphone and confirmed that libSystem.dylib(and libSystem.B.dylib) wasn't there. I unpacked the raw .ipsw package for iOS 4.2.1 and once again, I could not find a copy of libSystem.dylib there either. I unpacked the iPhoneSDK and MacOS SDK and I managed to find a copy of it in both, but that error just kept persisting. I copied libSystem.dylib, libSystem.B.dylib, tried all sorts of combinations of renaming to libc.dylib and still nothing but errors. I can't find a way to get it to recognize the file and link against it. I also tried linking against the libc.a located in the iphone SDK and that didn't work either. I checked what ./xgcc was firing off, and it was my freshly built copy of arm-apple-darwin-ld64 which should be fine. A little bit of background here. I built LLVM+Clang 2.8 with no errors, and I rebuilt the ODCCTools with some light modifications to get it to compile on Cygwin(I'll post my changes in a patch along with a tutorial if I can get this to work). I also grabbed the iphone-dev "includes" and "csu" project and those completed successfully, although there really is no point to them since I can't get it to link against crt0.a. I'm running out of ideas here. Can anyone help me out on this?

• Create Device Reccieve SMS Parse To Text ( SMS Gateway )

  - by Chris Okyen

  I want to use a server as a device to run a script to parse a SMS text in the following way. I. The person types in a specific and special cell phone number (Similar to Facebook’s 32556 number used to post on your wall) II. The user types a text message. III. The user sends the text message. IV. The message is sent to some kind of Device (the server) or SMS Gateway and receives it. V. The thing described above that the message is sent to then parse the test message. I understand that these three question will mix Programming and Server Stuff and could reside here or at DBA.SE How would I make such a cell phone number (described in step I) that would be sent to the Device? How do I create the device that then would receive it? Finally, how do I Parse the text message?

• What is a “pretty and proper OO” way for handling sessions and authentication?

  - by asdfqwer

  Is coupling these two concepts a bad approach? As of right now I'm delegating all session handling and whether or not a user desires to logout in my config.inc file. As I was writing my Auth class I started wondering whether or not my Auth class should be taking care of most of the logic in my config.inc. Regardless, I'm sure there's a more elegant way of handling this... Here is what I have in my config.inc (also a large chunk of this code is based on a reply I found on SO except I can't find the source ._.): ini_set('session.name', 'SID'); # session management session_set_cookie_params(24*60*60); // set SID cookie lifetime session_start(); if(isset($_SESSION['LOGOUT']) { session_destroy(); // destroy session data $_SESSION = array(); // destroy session data sanity check setcookie('SID', '', time() - 24*60*60); // destroy session cookie data #header('Location: '.DOCROOT); } elseif(isset($_SESSION['SID_AUTH'])) { // verify user has authenticated if (!isset($_SESSION['SID_CREATED'])) { $_SESSION['SID_CREATED'] = time(); } elseif (time() - $_SESSION['SID_CREATED'] > 6*60*60) { // session started more than 6 hours ago session_regenerate_id(); // reset SID value $_SESSION['SID_CREATED'] = time(); // update creation time } if (isset($_SESSION['SID_MODIFIED']) && (time() - $_SESSION['SID_MODIFIED'] > 12*60*60)) { // last request was more than 12 hours ago session_destroy(); // destroy session data $_SESSION = array(); // destroy session data sanity check setcookie('SID', '', time() - 24*60*60); // destroy session cookie data } $_SESSION['SID_MODIFIED'] = time(); // update last activity time stamp }

• Is there something special about the number 65535?

  2¹6-1 & 25 = 25 (or? obviously ?) A developer asked me today what is bitwise 65535 & 32 i.e. 2¹6-1 & 25 = ? I thought at first spontaneously 32 but it seemed to easy whereupon I thought for several minutes and then answered 32. 32 seems to have been the correct answer but how? 65535=2¹6-1=1111111111111111 (but it doesn't seem right since this binary number all ones should be -1(?)), 32 = 100000 but I could not convert that in my head whereupon I anyway answered 32 since I had to answer something. Is the answer 32 in fact trivial? Is in the same way 2¹6-1 & 25-1 =31? Why did the developer ask me about exactly 65535? Binary what I was asked to evaluate was 1111111111111111 & 100000 but I don't understand why 1111111111111111 is not -1. Shouldn't it be -1? Is 65535 a number that gives overflow and how do I know that?

• Should interfaces extend (and in doing so inherit methods of) other interfaces

  - by dreza

  Although this is a general question it is also specific to a problem I am currently experiencing. I currently have an interface specified in my solution called public interface IContextProvider { IDataContext { get; set; } IAreaContext { get; set; } } This interface is often used throughout the program and hence I have easy access to the objects I need. However at a fairly low level of a part of my program I need access to another class that will use IAreaContext and perform some operations off it. So I have created another factory interface to do this creation called: public interface IEventContextFactory { IEventContext CreateEventContext(int eventId); } I have a class that implements the IContextProvider and is injected using NinJect. The problem I have is that the area where I need to use this IEventContextFactory has access to the IContextProvider only and itself uses another class which will need this new interface. I don't want to have to instantiate this implementation of IEventContextFactory at the low level and would rather work with the IEventContextFactory interface throughout. However I also don't want to have to inject another parameter through the constructors just to have it passed through to the class that needs it i.e. // example of problem public class MyClass { public MyClass(IContextProvider context, IEventContextFactory event) { _context = context; _event = event; } public void DoSomething() { // the only place _event is used in the class is to pass it through var myClass = new MyChildClass(_event); myClass.PerformCalculation(); } } So my main question is, would this be acceptable or is it even common or good practice to do something like this (interface extend another an interface): public interface IContextProvider : IEventContextFactory or should I consider better alternatives to achieving what I need. If I have not provided enough information to give suggestions let me know and I can provide more.

• How should I start with Lisp?

  - by Gary Rowe

  I've been programming for years now, working my way through various iterations of Blub (BASIC, Assembler, C, C++, Visual Basic, Java, Ruby in no particular order of "Blub-ness") and I'd like to learn Lisp. However, I have a lot of intertia what with limited time (family, full time job etc) and a comfortable happiness with my current Blub (Java). So my question is this, given that I'm someone who would really like to learn Lisp, what would be the initial steps to get a good result that demonstrates the superiority of Lisp in web development? Maybe I'm missing the point, but that's how I would initially see the application of my Lisp knowledge. I'm thinking "use dialect A, use IDE B, follow instructions on page C, question your sanity after monads using counsellor D". I'd just like to know what people here consider to be an optimal set of values for A, B, C and perhaps D. Also some discussion on the relative merit of learning such a powerful language as opposed to, say, becoming a Rails expert. Just to add some more detail, I'll be developing on MacOS (or a Linux VM) - no Windows based approaches will be necessary, thanks. Notes for those just browsing by I'm going to keep this question open for a while so that I can offer feedback on the suggestions after I've been able to explore them. If you happen to be browsing by and feel you have something to add, please do. I would really welcome your feedback. Interesting links Assuming you're coming at Lisp from a Java background, this set of links will get you started quickly.
