  • What binary architectures should be cross-compiled when building Mac OS X packages?

    - by Alex Leach
    Currently, Apple's native binaries and libraries are distributed as fat files, with support for both i386 and x86_64 architectures. The SDK (Xcode 4.4 w/ command line tools) doesn't support cross-compiling powerpc binaries any more, so they can be safely ignored I think, but there doesn't seem to be any specific guidelines or recommendations about which Intel architectures to support. So, when compiling code for distribution on OS X, do people still cross-compile for the i386 architecture? Or are x86_64 binaries the only architecture worth bothering with nowadays?

  • MAC OS X: How to determine if filesystem is case sensitive?

    - by trojanfoe
    I have used the statfs(2) system call to get many characteristics of a Mac OS X filesystem, but it doesn't tell me if the filesystem is case-sensitive or not. I need this information as the application I am developing will be moving many files around and I want to detect potential loss of data due to files being moved from a case-sensitive filesystem to a case-insensitive filesystem. Can anyone suggest a way of detecting this?

  • Find UI components in real time run, under Android OS, it is possible?

    - by kimo
    Hi All, I want to know if I can find/reach UI components of running application under Android OS. it is possible to catch the Button/DDL/.. that was clicked by the user in real-time, example from other subject(web): In browser I can listen to the events and catch the DOM object that was clicked, in this way I can save the DOM object data. catching UI components that was changed by the user will give the option to save UI componentdata, and to perform the user actions automatic.

  • How to launch a dependent application on OS X?

    - by jldupont
    What is the programmatical mechanism by which an application can be launched at a result of another one being launched? E.g. upon launching iTunes, the Last.fm desktop launches too. Or it is just a question of substituting a "batch file" of some sort? Note: OS X newbie.

  • Real server, Multiple IP Addresses, HyperV Virtual Server, How to partition IPs across real and Virtual NICs

    - by Steven_W
    This is a slightly difficult problem to explain without same basic background information - I'll try and refine the question later as necessary Originally, I have a single hosted server (Win 2008R2) with the following range of 8 IP addresses. - Single NIC - IP: x.x.128.72 -> x.x.128.79 - Subnet: x.x.255.192 - GW: x.x.128.65 After installing Hyper-V and setting up a single virtual server on the same box, I then wanted to assign one of the IP addresses to the virtual server, leaving everything else running normally. -- Firstly, I tried using the "External" network, but (even after setting IPs on the "Virtual Adapter" similar to Here but struggled to get networking running at all. I needed to keep the server running (otherwise I would have spent more time pursuing this approach) Q1 ... Was this a sensible thing to do ? Should I have carried on down this route ? -- I then decided to try different approach - Set the HyperV network to "Internal" (visible to Management OS) - Physical NIC - IP: x.x.128.72 -> x.x.128.75 - Subnet: x.x.255.192 - GW: x.x.128.65 - Virtual NIC - IP: x.x.128.78 - Subnet: x.x.255.252 - GW: x.x.128.72 ... { The same as the IP of the physical NIC ) - Virtual OS-NIC - IP: x.x.128.77 - Subnet: x.x.255.252 - GW: x.x.128.78 ... { The same as the IP of the host virtual-NIC ) -- Surprisingly enough, this approach actually worked, and I was able to connect from all the following: - Internet to/from physical NIC (x.x.128.72) - physical NIC (x.x.128.72) to virtual-OS-NIC (x.x.128.77) e.g. testing via ping + FTP - Internet to/from virtual-OS-NIC (x.x.128.72) -- The problem I have is that this approach seems to only last for a short while (a few hours). After this time, it seems that I lose the ability to connect from Virtual-OS-NIC to/from the internet (but I can still connect from the host-OS to the virtual-OS and from the host-OS to the internet) I have re-tested this a couple of times with the same results ... I leave the server on for a few hours (e.g. overnight), and when I come back in the morning, the Virtual-OS loses the ability to route to the internet -- I'm not quite sure what to look at next (or whether I'm going about this completely the wrong way ) One "possible relevant item" is that the host-OS is also running RRAS (Routing and Remote Access), but this is only to run a simple VPN -- Q2 - Wheat should I be looking at next ? (Any good references / recommendations of what to try) Would appreciate any thoughts or comments (even if you tell me I'm going about this the wrong way)

Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)

  • Unable to set background image using python (2.7.3), bash and gnome3

    - by malon
    #!/usr/bin/env python import os bashCommand = "gsettings set org.gnome.desktop.background picture-uri file:///home/malon/autowallpaperchanger/" + pic_name print bashCommand os.system(bashCommand) Print result: gsettings set org.gnome.desktop.background picture-uri file:///home/malon/autowallpaperchanger/wallpaper-1252048.jpg Copying and pasting the print result into a terminal makes the change successfully, so the command is correct, but os.system isn't processing the request correctly for some reason. In the full script (posted below), I use os.system for a different reason immediately before (wget) and that works fine. Thank you! Full script: http://pastebin.com/R90GTmBZ

  • MySQL Binary Storage using BLOB VS OS File System: large files, large quantities, large problems.

    - by Quantico773
    Hi Guys, Versions I am running (basically latest of everything): PHP: 5.3.1 MySQL: 5.1.41 Apache: 2.2.14 OS: CentOS (latest) Here is the situation. I have thousands of very important documents, ranging from customer contracts to voice signatures (recordings of customer authorisation for contracts), with file types including, but not limited to jpg, gif, png, tiff, doc, docx, xls, wav, mp3, pdf, etc. All of these documents are currently stored on several servers including Windows 32 bit, CentOS and Mac, among others. Some files are also stored on employees desktop computers and laptops, and some are still hard copies stored in hundreds of boxes and filing cabinets. Now because customers or lawyers could demand evidence of contracts at any time, my company has to be able to search and locate the correct document(s) effectively, for this reason ALL of these files have to be digitised (if not already) and correlated into some sort of order for searching and accessing. As the programmer, I have created a full Customer Relations Management tool that the whole company uses. This includes Customer Profiles management, Order and job Tracking tools, Job/sale creation and management modules, etc, and at the moment any file that is needed at a customer profile level (drivers licence, credit authority, etc) or at a job/sale level (contracts, voice signatures, etc) can be uploaded to the server and sits in a parent/child hierarchy structure, just like Windows Explorer or any other typical file managment model. The structure appears as such: drivers_license |- DL_123.jpg voice_signatures |- VS_123.wav |- VS_4567.wav contracts So the files are uplaoded using PHP and Apache, and are stored in the file system of the OS. At the time of uploading, certain information about the file(s) is stored in a MySQL database. Some of the information stored is: TABLE: FileUploads FileID CustomerID (the customer id that the file belongs to, they all have this.) JobID/SaleID (the id of the job/sale associated, if any.) FileSize FileType UploadedDateTime UploadedBy FilePath (the directory path the file is stored in.) FileName (current file name of uploaded file, combination of CustomerID and JobID/SaleID if applicable.) FileDescription OriginalFileName (original name of the source file when uploaded, including extension.) So as you can see, the file is linked to the database by the File Name. When I want to provide a customers' files for download to a user all I have to do is "SELECT * FROM FileUploads WHERE CustomerID = 123 OR JobID = 2345;" and this will output all the file details I require, and with the FilePath and FileName I can provide the link for download. http... server / FilePath / FileName There are a number of problems with this method: Storing files in this "database unconcious" environment means data integrity is not kept. If a record is deleted, the file may not be deleted also, or vice versa. Files are strewn all over the place, different servers, computers, etc. The file name is the ONLY thing matching the binary to the database and customer profile and customer records. etc, etc. There are so many reasons, some of which are described here: http://www.dreamwerx.net/site/article01 . Also there is an interesting article here too: sietch.net/ViewNewsItem.aspx?NewsItemID=124 . SO, after much research I have pretty much decided I am going to store ALL of these files in the database, as a BLOB or LONGBLOB, but there are still many considerations before I do this. I know that storing them in the database is a viable option, however there are a number of methods of storing them. I also know storing them is one thing; correlating and accessing them in a manageable way is another thing entirely. The article provided at this link: dreamwerx.net/site/article01 describes a way of splitting the uploaded binary files into 64kb chunks and storing each chunk with the FileID, and then streaming the actual binary file to the client using headers. This is a really cool idea since it alleviates preassure on the servers memory; instead of loading an entire 100mb file into the RAM and then sending it to the client, it is doing it 64kb at a time. I have tried this (and updated his scripts) and this is totally successful, in a very small frame of testing. So if you are in agreeance that this method is a viable, stable and robust long-term option to store moderately large files (1kb to couple hundred megs), and large quantities of these files, let me know what other considerations or ideas you have. Also, I am considering getting a current "File Management" PHP script that gives an interface for managing files stored in the File System and converting it to manage files stored in the database. If there is already any software out there that does this, please let me know. I guess there are many questions I could ask, and all the information is up there ^^ so please, discuss all aspects of this and we can pass ideas back and forth and teach each other. Cheers, Quantico773

  • How to find out where alias (in the bash sense) is defined when running Terminal in Mac OS X

    - by Richard Fuhr
    How can I find out where an alias is defined on my system? I am referring to the kind of alias that is used within a Terminal session launched from Mac OS X (10.6.3). For example, if I enter the alias command with no parameters at a Terminal command prompt, I get a list of aliases that I have set, for example, this is one of them alias mysql='/usr/local/mysql/bin/mysql' However, I have searched all over my system using Spotlight and mdfind in various startup files and so far can not find where this alias has been defined ( I did it a long time ago and didn't write down where I assigned the alias).

  • What are the preferred versions of Vim and Emacs on Mac OS X?

    - by Michiel de Mare
    For those of us that like to use the graphical version of Vim or Emacs, instead of the console version, which version do you recommend? For Vim, there's Mac OS X Vim, MacVim, Vim-Cocoa. For Emacs, CarbonEmacs, XEmacs, and Aquamacs. Are there more? Which of these are ready for prime-time? If it's a tough call, what are the trade-offs? Are all of these still being maintained? No discussion of Vim vs. Emacs, if you don't mind, or comparisons with other editors.
