  • Software-related but not programming-specific questions

    - by jayrdub
    I have often fought the urge to ask questions that I know aren't appropriate on SO, because I personally haven't come across another online group who's opinions I would trust as much. What sites do you frequent that you have found good participation from a smart group of people where you can ask questions that are related to software, but not programming problems? This community also has a vast depth of knowledge about things related to software like marketing, graphics/UI, running a small business, working in bad jobs, etc. that would greatly benefit everyone else. Where do we go to tap all that knowledge? On stackoverflow.uservoice.com there is a popular suggested feature to sanction, or add to SO, a place to hold discussions that aren't about specific programming questions. It seems that the suggestion has been denied in the past though.

  • what great software engineers know or aspiring ones should know?

    - by trojanwarrior3000
    I do not mean any particular language or methodology. But basics( one have abstracted from ones experience and interaction with smarter people in this field) one should have including concepts, practical issues, tips/techniques/tricks one should be aware of.For example the lessons or ideas may relate to programming,testing,design,project schedules, that are really useful in daily life of software engineer/developer etc ? This may be a good question because it looks not to specific, however experience of many is better than reading from books.I find discussions much helpful than books.Hope every one will have some lessons/ideas to contribute.please substantiate with atleast one example.

  • Books recommendation to learn about java networking

    - by elec
    In order to cover for my (glaring) lack of knowledge in the basics of networking, I'm looking for a book which would ideally cover: - 1 or 2 chapters on the transport layer: tcp, udp... - 1 or 2 chapters on the application layer: http, dns... - rest of the book would be devoted to pratical way of sending data across the wire using Java-related technologies. This would involve discussions about existing products (eg. hessian, protobuf, thrift, tibco...) , performances comparisons, case studies...etc.. Does such a book exist ?

  • Read entire file in Scala?

    - by Brendan OConnor
    What's a simple and canonical way to read an entire file into memory in Scala? (Ideally, with control over character encoding.) The best I can come up with is: scala.io.Source.fromPath("file.txt").getLines.reduceLeft(_+_) or am I supposed to use one of Java's god-awful idioms, the best of which (without using an external library) seems to be: import java.util.Scanner import java.io.File new Scanner(new File("file.txt")).useDelimiter("\\Z").next() From reading mailing list discussions, it's not clear to me that scala.io.Source is even supposed to be the canonical I/O library. I don't understand what its intended purpose is, exactly. ... I'd like something dead-simple and easy to remember. For example, in these languages it's very hard to forget the idiom ... Ruby open("file.txt").read Ruby File.read("file.txt") Python open("file.txt").read()

  • Facebook Connect Post Feed from iPhone App without preview Broken!? URGENT!

    - by nephilite
    Hello All: I just downloaded the latest FBConnect build, popped in my keys and getting a mysterious hanging error only when I try to post a feed without previewing (setting preview to zero). The activity indicated disappears and the blank dialog window just hangs there. (This mirrors what I was getting on the app I was developing). If I try to post a feed with preview it works; set preview to zero it just hangs. Again; thats with the sample project "Publish Feed" button. Hitting getting permission button and then Publish Feed does same thing...... Other Developers have confirmed seeing this too...Apps that have previously had working feed posts have been broken for weeks. Discussions on facebook connect forum seem to be related to this. More Info Here: http://forum.developers.facebook.com/ I have to submit my app to apple in less than 3 hours... please assist!

  • Xcode: code loses syntax coloring

    - by ColorMeFamous
    I find that in various situations Objective-C code in Xcode 3.1 (Leopard) can fail to get appropriate syntax coloring after typing or lose coloring that it had. This isn't just a "refresh" issue with new custom symbols -- but affects Cocoa framework symbols as well. Sometimes CMD-a to select all text on the code page will make the coloring (re)appear, sometimes double-clicking on a line to select it will work, sometimes I have to add/delete a space in a symbol to get that symbol to (re)color. Rebuilding, or closing/reopening the project may or may not work. Is this a known issue with Xcode? For something so annoying to me, I'm not finding the plentiful discussions of it on SO and elsewhere I'd expect. And is there any command to force global syntax recoloring?

  • Base64 Android encode to PHP decode make error

    - by studio lambda
    I'm a french guy, so, I'm sorry for my english... I'm developing an Android App which communicate with a PHP REST service. So, when I try to encode an image file into Base64 like this : InputStream fileInputStream = context.getContentResolver().openInputStream(uri); BufferedInputStream in = new BufferedInputStream(fileInputStream); StringWriter out = new StringWriter(); int b; while ((b = in.read()) != -1) out.write(b); out.flush(); out.close(); in.close(); String encoded = new String(android.util.Base64.encode(out.toString() .getBytes(), android.util.Base64.DEFAULT)); On server side, I make : $data=base64_decode(chunk_split($base64BinaryData)); The result is that my image file is corrupted! INFO : the image is made by an Intent to android.provider.MediaStore.ACTION_IMAGE_CAPTURE Activity in Emulator mode (avd 5554) I've already read lots of discussions about similar problem but nothing fix my bug. thanks for help Regards,

  • Is -1 a magic number? An anti-pattern? A code smell? Quotes and guidelines from authorities

    - by polygenelubricants
    I've seen -1 used in various APIs, most commonly when searching into a "collection" with zero-based indices, usually to indicate the "not found" index. This "works" because -1 is never a legal index to begin with. It seems that any negative number should work, but I think -1 is almost always used, as some sort of (unwritten?) convention. I would like to limit the scope to Java at least for now. My questions are: What are the official words from Sun regarding using -1 as a "special" return value like this? What quotes are there regarding this issue, from e.g. James Gosling, Josh Bloch, or even other authoritative figures outside of Java? What were some of the notable discussions regarding this issue in the past?

  • Chipmunk warning still present with --release

    - by Kaliber64
    I'm using Python27 on Windows 7 64-bit. I downloaded the source for Chipmunk 6.2.x and compiled Pymunk with --release and -c ming32. Almost zero problems. Lots of path not found cause I'm bad. All prints seem to have disappeared but I get spammed with EPA iteration warnings. I've seen a couple discussions but no solutions. Possible chipmunk betas to fix the float errors causing the double truths causing the warning. I picked the latest stable version I think. My program is seriously bogged down with all the prints. class NullDevice(): def write(self, s): pass sys.stdout=NullDevice() Does not disable the C prints .< Any help?

  • Pros and Cons on where to place business logic: app level or DB

    - by Juri
    Hi, I always again encounter discussions about where to place the business logic: inside a business layer in the application code or down in the DB in terms of stored procedures. Personally I'd tend to the 1st approach, but I'd like to hear some opinions from your part first, without influencing you with my personal views. I know there doesn't exist a one-size-fits-all solution and it often depends on many factors, but we can discuss about that. Btw, we are in the context of web applications and our current approach is to have UI layer which accepts UI input and does a first, client-side validation Business layer with a number of service-classes which contains the business logic including validation for user input (server-side) Data Access Layer which calls stored procedures from the DB for doing persistency/read operations Many people however tend to move the business layer stuff (especially regarding the validation) down to the DB in terms of stored procedures. What do you think about it? I'd like to discuss.

  • Is it possible to load a new Applescript scripting addition whilst my script is running?

    - by jkp
    According to various documents and discussions this used to be possible: you needed a block something like this in your script: try tell me to «event ascrgdut» end try tell me to doTheFunkyNewThing The event corresponds to hidden event with the undocumented C constant kUpdateAEUT (see here for the declaration of the constant) which should force the scripting additions to be reloaded. I've written a scripting addition and played around with this method of getting it to load but I have had no luck at all. I can only make it load by starting my script after the extension has been installed. Does anyone know if there is a way to make this work? Has this functionality been disabled in more recent OS X releases? I'm using OS X 10.6.2 FWIW.

  • caching static files for ruby on rails application using nginx

    - by splintercell
    I have been trying for some time to serve & cache static files for my rails app using nginx. the rails app server runs mongrel_cluster and is deployed on a different host than that of nginx. following many of the available discussions I tried the following server { listen 80; server_name www.myappserver.com; ssl on; root /var/apps/myapp/current/public; location ~ ^/(images|javascripts|stylesheets)/ { root /var/apps/myapp/current; expires 10y; } location / { proxy_pass http://myapp_upstream; } } But nginx fails to find the images and to load the css and js files. Can anyone help me out here? My aim is to configure nginx in such a way that it caches the static files till expiry. Please suggest me some way to achieve this or am I missing any point here?

  • Develop an classic UI or be bold with a newer design?

    - by DeanMc
    Forgive me if this is the wrong place but I am curious as to how other programmers feel about this topic: I am currently working on my portfolio site, it is being designed and built in silverlight 4. I initially started off with a typical stylised e-folio theme much like a standard website in terms of layout and flow. As I work more in the concept stages something has struck me. Am I trying to shoe-horn yesterday into today? What I am talking about is UI expectations. I'm all for clean user interfaces but that does not mean they should not take advantage of new concepts in presentation right? If you where to develop a site in silverlight as your own portfolio piece would you stick to the tried and tested "website" feel or would you try to come up with a UI that is intuitive and complements the technology? I feel that UI discussions are all the more important now that all forms of web development are allowing better methods to engage the user.

  • Django multiple generic_inline_formset in a view

    - by Can Burak Cilingir
    We have a bunch of formsets: EmailAddressInlineFormSet = generic_inlineformset_factory( EmailAddress, extra=1, exclude=["created_by","last_modified_by"]) emailaddressformset = EmailAddressInlineFormSet( instance=person, prefix="emailaddress") # [ more definitions ] and, in the view, we process them as: emailaddressformset = EmailAddressInlineFormSet( request.POST, instance=person, prefix="emailaddress") # [ more definitions ] So, nothing fancy or unordinary. The unfortunate or unordinary fact is, we have 15 of these formsets, one for email addresses, other for phone numbers etc. so the view code is ugly and not-so-manageable. What would be the most unhackish way to handle this number of formsets in a single view? At the end -i guess- I'm looking for a class or a functionality like multiple_generic_inline_formset and open to all kind of suggestions or discussions.

  • Are there any good videos out there on Java Design Patterns?

    - by Becky Reamy
    My team would like to spend some time at lunch learning design patterns. Previously, we watched some videos on Javascript which we found very useful as a way to start discussions. We would like to do the same thing with design patterns so that we don't have to spend a lot of time (outside of work) researching individual patterns in order to give a presentation. I did a little searching and came up fairly empty handed. Any help would be appreciated. It doesn't even have to be a video, even something that we can listen to (maybe a book on tape even).

  • Websites with horizontal accordion effect

    - by peterdp
    Hi Folks, I was delighted with the responses folks offered to the question about horizontal sliding panels that I thought I would try again. In subsequent discussions with my colleagues, it became clearer that we would also like to consider horizontal accordion effects, so I am looking for some concrete, real world examples. Soo... I would once again be most grateful to the stalwart StackOverflowians who could take a moment to paste links to their favorite website(s) that use a horizontal accordion effect well. Extra kudos if you can promote your own site! Thanks so very much if you can help!

  • Encrypt text using a number

    - by Adam Matan
    Project Euler I have recently begun to solve some of the Project Euler riddles. I found the discussion forum in the site a bit frustrating (most of the discussions are closed and poorly-threaded), So I have decided to publish my Python solutions on launchpad for discussion. The problem is that it seems quite unethical to publish these solutions, as it would let other people gain reputation without doing the programming work, which the site deeply discourages. My Encryption problem I want to encrypt my answers so that only those who have already solved the riddles can see my code. The logical key would be the answer to the riddle, which is always numeric. In order to prevent brute-force attacks on my answers, I want to find an encryption algorithm that takes a significantly long time (few seconds) to run. Do you know any such algorithm? I would fancy a Python package, which I can attach to the code, over an external program that might have portability issues. Thanks, Adam

  • Where does one get Visual Source Safe 2005?

    - by strongopinions
    I would like to install VSS 2005 so I can work on a project that is stored under it. Does anyone have any idea where the VSS 2005 client can be obtained? It does not appear to be on my VS2005 install disc (although that is for Team Suite). I cannot get any help from Google. I have an MSDN license (AA edition) but it doesn't seem to be there. This is a real product right? Just to clarify preemptively based on some of the discussions I see on Google when I search for things like "VSS 2005," I am aware of the flaws in VSS and I still need to get it working; I am not interested in converting the project to Subversion; I am not able to transfer it to TFS; I am not able to upgrade the project to VS2008. Thanks.

  • In SharePoint, how can the "Issue ID" column of an issues list be included in the detail form (DispF

    - by Jesse C. Slicer
    We've created a pretty standard issue tracking system based off of SharePoint's template with just a few extra columns. On the list view (AllItems.aspx), the first column is called "Issue ID" and has a number. Our developers and QC use that number in discussions. However, that number doesn't seem to want to show up on the detail form (DispForm.aspx) nor in the alert email. Can this field be included in at least one of these communication methods? If so, how? Thank you.

  • Adding image to navigation bar

    - by 4thSpace
    I'd like an image to take up all of a navigation bar. This is the navigation that comes with a navigation based app. It appears on the RootViewController with the accompanying UITableView. I've seen some examples of how this might work. Set navigation bar title: UIImage *image = [UIImage imageNamed:@"TableviewCellLightBlue.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; [self.navigationController.navigationBar.topItem setTitleView:imageView]; The problem there is it only covers the title rather than the entire navigation bar. There is also this thread: http://discussions.apple.com/message.jspa?messageID=9254241#9254241. Towards the end, the solution looks to use a tab bar, which I'm not using. It is that complicated to set a navigation bar background? Is there some other simpler technique? I'd like to have a background for the navigation and still be able to use title text.

  • Keeping the application state - deploy/install apk

    - by Buffalo
    I'm trying to have my application minimized when paused and then when it's resumed, it should be restored to its previous state, not recreated. This works perfectly when deploying the application on a device/emulator from Eclipse. The problem occurs when I get the apk (either from bin\ or from Project - Android tools - Export signed application package) and install it on a device with a file browser (Astro): the application is destroyed when paused and then recreated. I can call moveTaskToBack(true); in my activity, yet it will still be recreated when launching it. All the discussions around this are based on achieving the opposite: closing the application when minimizing it. Is there any way of achieving what I want?

  • Using SQL to get the Last Reply on a Post

    - by Anraiki
    I am trying to replicate a forum function by getting the last reply of a post. For clarity, see PHPBB: there are four columns, and the last column is what I like to replicate. I have my tables created as such: discussion_id (primary key) user_id parent_id comment status pubdate I was thinking of creating a Link Table that would update for each time the post is replied to. The link table would be as follow: discussion_id (primary key) last_user_id last_user_update However, I am hoping that theres a advance query to achieve this method. That is, grabbing each Parent Discussion, and finding the last reply in each of those Parent Discussions. Am I right that there is such a query?

  • How to practically customize IE context menu?

    - by bionicoder
    I need to add one menu item in IE context menu. It is similar with Google customized context menu "Search Google for xxx" when you right click on IE. I did a research and found that overriding IDocHostUIHandler::ShowContextMenu in a IE BHO can customized IE context menu. The sample project can be found in Popup blocker project published in codeproject. It works well and is easy to implement. However this approach has a problem. The problem is it will conflict with other add-ons' context menu customization per MSDN. In MSDN Internet Explorer Center forum, there are some discussions about this topic. However there is not a proper implementation posted. If anybody has experience on this, please share your idea. Thanks!

  • implementing type inference

    - by deepblue
    well I see some interesting discussions here about static vs. dynamic typing I generally prefer static typing, due to compile type checking, better documented code,etc. However I do agree that they do clutter up the code if done the way Java does it, for example. so Im about to start building a language of my own and type inference is one of the things that I want to implement, in a functional style language... I do understand that it is a big subject, and Im not trying to create something that has not been done before, just basic inferencing... any pointers on what to read up that will help me with this? preferably something more pragmatic/practical as oppose to more theoretical category theory/type theory texts. If there's a implementation discussion text out here, with data structures/algorithms, that would just be lovely much appreciated
