  • Mac OSX Programming for long time Linux geek

    - by DarenW
    I've written software on Linux since 1995 but must get up to speed with app development on the Mac. I have no experience on that platform. Obviously I should get my hands on some appropriate hardware. What are good books, tutorial websites, and other resources for experienced devs getting started on Mac? Not just APIs and app internals, but also including how does one install an app, debug it, etc?

  • What is the process of turning HTML into Postscript programmatically

    - by Dean
    I am trying to understand what the process is of turning HTML into a PDF/Postscript programmatically All Google searches turn up libraries to do this, but I am more interested in the actual process required. I know you could just set up a Postscript printer and print directly to that, but some of these libraries appear to create the PDF on the fly to allow previews etc. has anyone had any experience in this, or can provide any guidance?

  • Facebook Connect on iPhone question

    - by TheGambler
    When you use facebook connect on the iPhone do you have to use the supplied login button and login screen built into the framework? The reason I ask is because I'm also using twitter and I would like to have the same user experience when they log in to user as they have when they log in to facebook. So I can either replicate the login screen facebook connect uses for twitter or just not use the facebook connect login screen all together.

  • Maintaining a secure database of user logins and info?

    - by Rafe Kettler
    I want to have a login form on a charity website I am building (it's for a friend, and I'm learning on the go), and I want to know what languages/software should I learn to build databases for user logins and info? Note: it HAS to be secure and relatively simple to learn for someone with moderate programming experience. Update: I understand that CMSs offer good tools for logins etc. but I want to do this all by myself.

  • Javascript (and HTML rendering) engine without a GUI for automation?

    - by MTsoul
    Are there any libraries or frameworks that provide the functionality of a browser, but do not need to actually render physically onto the screen? I want to automate navigation on web pages (Mechanize does this, for example), but I want the full browser experience, including Javascript. Thus, I'd like to have a virtual browser of some sort, that I can use to "click on links" programmatically, have DOM elements and JS scripts render within it, and manipulate these elements. Solution preferably in Python, but I can manage others.

  • C triple dereferencing

    - by Kiran
    I have used functions with doubly dereferenced pointers (**var) to return values. However, I was recently asked a question to figure out a use-case where a triple dereferencing (***var) may be needed. I couldn't think of any practical scenario. Does anyone have any experience here?

  • Best programming language for a beginner to learn?

    - by Dean
    I am teaching my friend how to program in C, he has no programming experience. He wants to learn C so that he can program different microprocessors. I have suggested he learn another language something like java or ruby so that he can learn basics before moving on to a language like C. Is this advisable or should i just teach him C?

  • On Windows 7, how can I tell if a recording is multi-channel without third party tools? [migrated]

    - by engineerchuan
    A customer has an audio that is confidential and can't send it to me. He also would not like to install other tools. He has a basic Windows 7 install. Is there any way to tell whether the recording is one channel or two channel? Normally, I would just get the audio and soxi it. Or, I would tell him to install Audacity or equivalent sound editor and open it up. I also thought that if you right clicked and looked at the size, bit rate, and length, you could get number of channels but bit rate already factors in number of channels. Sorry I'm not giving you a lot to work with.

  • PostgreSQL disaster recovery options

    - by Alex
    My customer has quite a large (the total "data" folder size is 200G) PostgreSQL database and we are working on a disaster recovery plan. We have identified three different types of disasters so far: hardware outage, too much load and unintentional data loss due to erroneously executed bad migration (like DELETE or ALTER TABLE DROP COLUMN). First two types seem to be easy to mitigate but we can't elaborate a good mitigation plan for the third type. I proposed to use ZFS and frequent (hourly) snapshots but "ZFS" means "OpenIndiana" these days and our Ops engineers do not have much expertise in it, so using OpenIndiana imposes another risk. Colleagues try to convince me that restoring from PostgreSQL PITR backup can be as fast as restoring from a ZFS snapshot but I highly doubt that replaying, say, 50G of archived WALs can be considered "fast". What other options are we missing? Is ZFS an only viable alternative? Can we get a fast Pg DB restore time in the Linux environment?

  • Language/Framework support for Interacting With CouchDB

    - by Gordon
    I am interested in knowing if there are any server-side web application frameworks which integrate nicely with CouchDB? Does anyone have any experience in doing this? It seems like a dynamic language would be well-suited for playing with the JSON, but I am more interested in hearing about how it would fit in with the framework and the application's design.

  • Using HSQLDB in production environments

    - by lewap
    I want to use HSQLDB in a production environment for stroring some data in memory and for data export using files. Does anybody have experience with using hsqldb in production environments? Is hsqldb treating server resources gracefully and does it cleanup unused resources properly?

  • What determines the time to first ping response in an OS?

    - by Stuart Woodward
    When a server (say Windows, Linux) is rebooted, it will take some time to respond to ping. I'm assuming that the software firewall has to be up before pings will be returned as there might be a setting to disable ping responses. Everyone knows that Windows and Linux have have totally different architectures so lets treat them separately. The answer I'm looking for is "After XXX is running, pings will be returned." It would be helpful to know where in the boot order this is too. i.e. at the start or end. I ask because we get questions from a customer about why it takes so long to respond to ping after creating a Virtual Machine. I'm sure this is just an artefact of the OS boot behaviour.

  • Is there a way to set up message moderation in Exchange 2007?

    - by Nate Pinchot
    Is there a way to get a feature in Exchange 2007 similar to message moderation in Exchange 2010 through the use of third party tools or otherwise? I've Googled things like "exchange 2007 outbound email approval" to no avail. We are working on getting Exchange 2010 implemented but I need an interim solution if at all possible. The reason for this is from a customer service perspective. I am willing to use a small process to be a smart host if needed. I would appreciate any suggestions or advice. Edit: My apologies, I should have been more clear that I am trying to moderate/approve outgoing email from certain users, not moderate/approve email sent to a distribution group.

  • Powder Physics Games

    - by frinkz
    Does anyone have any experience with this sort of thing? I'm talking about applets like this http://dan-ball.jp/en/javagame/dust/ I'm really interested in how they work, it seems more like fluid-dynamics than regular game physics. Does anyone know any open source variations, or any hints on how they might work? I think it would be really fun and challenging to work on something like this, but I'm not sure where to start researching... Thanks :)

  • jQuery check on wordchange rather than "change" trigger

    - by benhowdle89
    I have a input that the user types a search parameter into, at the moment i have it on keyup to do a POST ajax request to a PHP script that returns search results. however its firing off 50 billion (not literally) post requests in about 10 seconds (as the user types) which slows the whole experience down. Can i use jQuery to detect a "wordup" rather than "keyup" by detecting the use of the space bar? Does this make sense?
