  • basic picture editing software for Mac OS X

    - by George2
    I am using a MacBook Pro running Mac OS X 10.5. I am new to this development environment, and previously worked on Windows. I want to do very basic image editing, like cut a portion of an image, add some text label to the image, circle some part of the image, etc. I am downloading acornfree from this Url, but when executing acornfree, it said the Mac OS I am using is not supported. Any ideas how to fix this issue or any other free image editing software to recommend (and could be used for my specific Mac OS platform)? http://flyingmeat.com/acorn/acornfree.html Thanks in advance

  • 12.04 grub unable to boot on /sde, upgrade-grub and boot-repair failed, please help

    - by VGR
    My problem is I've 4 disks in a raid array listed as sda, sdb... sdd and grub 2 refuses to boot on /sde (the 5th disk, standalone and containing a clean install of 12.04 64 bits). I tried all solutions but all fail. (live CD/USB with grub-setup, also tried repair-grub, and tried also in the "grub rescue" set prefix= etc). I also tried to deactivate the RAID array in the BIOS, but I'd rather not destroy it, and I didn't find a way to make the standalone disk as '/sda1' (this would satisfy grub). In the BIOS, the would-be /sda is the only bootable hard disk; it ends up as /sde and grubs complains. I've made repair-grub issue a pastebin. I always end up in grub-rescue and I'm stuck. I need Ubuntu to boot so that I can add the device array handler for my disks. I can't switch the disks and I can't disconnect the SATA RAID controller. I need: (a) a workaround so that grub starts on /sde; or (b) a way to change the order in which Ubuntu sees the disks, at boot time. I could then provide grub with a /sda1. Thanks a lot. up please thanks a lot it's not the same problem as booting ubuntu from raid. My RAID array serves only of data repository windows had no problem with this configuration

  • How to stop Windows 7 from automatically connecting to unsecure wifi network

    - by Remi Despres-Smyth
    One of my neighbors has an unsecure wifi network called WLAN. At one point in the past, I accidentally connected to it, and disconnected immediately when I noticed. Now, when I open my laptop at home, it sometimes connects to the WLAN network first, before trying my (secured) home wifi network. The information I've found regarding this issue seems to suggest this network should have a profile on the "Manage wireless networks" screen - but it does not. How do I tell Windows 7 to never connect to networks with SSIDs called WLAN? Or to never connect to unsecured networks without confirming with me first?

  • Linux Bridge, Samba netbios name/hostname access

    - by Christopher Wilson
    I am currently running a linux bridge in the following configuration ADSL Modem: 192.168.1.1 Linux Bridge: eth0: 192.168.1.2 eth1: no address Wireless Router: 192.168.0.1 My issue is that i cannot access the "Linux Bridge" shares using the WINS name of the server via client systems (yes i understand it is a transparent bridge but i can access it via the 192.168.1.2 address this is not on the same subnet as the client systems).

  • Effective way to check if an Entity/Player enters a region/trigger

    - by Chris
    I was wondering how multiplayer games detect if you enter a special region. Let's assume there is a huge map that is so big that simply checking it would become a huge performance issue. I've seen bukkit (a modding API for Minecraft servers) firing an Event on every single move. I don't think that larger games do the same because even if you have only a few coordinates you are interested in, you have to loop through a few trigger zone to see if the player is inside your region - for every player. This seems like an extremely CPU-intense operation to me even though I've never developed something like that. Is there a special algorithm that is used by larger games to accomplish this? The only thing I could imagine is to split up the world into multiple parts and to register the event not on the movement itself but on all the parts that are covered by your area and only check for areas that are registered in the current part. And another thing I would like to know: How could you detect when someone must have entered a trigger but you never saw him directly in it since his client only sent you an move packet shortly before entering and after leaving the trigger area. Drawing a line and calculate all colliding parts seems rather CPU intensive if you have to perform it every time.

  • Why is APC (PHP Accelerator) Only caching apc.php?

    - by amvx
    I installed PHP5,APC and XDEBUGGER with the install script found here: Dreamhost PHP+APC Install Instructions/Script All systems seem to be working... except... I added the apc.php to see the caching stats of APC (GUI Interface), and it showed that only apc.php file was being cached despite having installed wordpress and prestashop under the same domain, installing and running those php scripts. I wonder if I did something wrong... but my php5 is running as a cgi/fastcgi. I think I might have read somewhere about there being some issue with this. Not sure. Any help is of coursed appreciated.

  • Frequent Disconnects with an Intel 3945ABG Wireless Card

    - by Alex Forsythe
    I'm brand new to Ubuntu, and I really love it so far, but one issue I have encountered is that my WLAN is disconnecting about every 5-10 minutes. Often times the connection is repaired automatically, but sometimes the network manager will repeatedly reject my encryption key (which of course is correct). Occasionally after a disconnect, the wireless network fails to show up at all. The only way I can solve this seems to be by completely restarting Ubuntu or connecting with a USB wireless adapter. I am using WPA/WPA2 encryption, which I've read can cause problems with network-manager, but I experience the exact same issues with WICD. I should probably note that I've not experienced any of these issues using Windows 7 on my other partition. I have a hunch that there may be a better driver out there for my card, but I have no idea how to go about searching for it or installing it. Any help would be really appreciated! lsb_release -a No LSB modules are available.

  • Building a Redundant / Distrubuted Application

    - by MattW
    This is more of a "point me in the right direction" question. I (and my team of 3) have built a hosted web app that queues and routes customer chat requests to available customer service agents (It does other things as well, but this is enough background to illustrate the issue). The basic dev architecture today is: a single page ajax web UI (ASP.NET MVC) with floating chat windows (think Gmail) a backend Windows service to queue and route the chat requests this service also logs the chats, calculates service levels, etc a Comet server product that routes data between the web frontend and the backend Windows service this also helps us detect which Agents are still connected (online) And our hardware architecture today is: 2 servers to host the web UI portion of the application a load balancer to route requests to the 2 different web app servers a third server to host the SQL Server DB and the backend Windows service responsible for queuing / delivering chats So as it stands today, one of the web app servers could go down and we would be ok. However, if something would happen to the SQL Server / Windows Service server we would be boned. My question - how can I make this backend Windows service logic be able to be spread across multiple machines (distributed)? The Windows service is written to accept requests from the Comet server, check for available Agents, and route the chat to those agents. How can I make this more distributed? How can I make it so that I can distribute the work of the backend Windows service can be spread across multiple machines for redundancy and uptime purposes? Will I need to re-write it with distributed computing in mind? I should also note that I am hosting all of this on Rackspace Cloud instances - so maybe it is something I should be less concerned about? Thanks in advance for any help!

  • Can't enable Windows XP file sharing

    - by colemanm
    The "sharing and security" option in the right-click context menu on a folder is no longer there. The File and Print sharing option is "installed" and turned on in the TCP/IP properties, but the ability to share any folders has disappeared, along with all previously shared folders. Where should I check to see what the issue is here? EDIT From comments below: "Server" service is not starting, see comment below for more... Firewall is completely disabled, too. This is XP Pro, Simple File Sharing is turned on. We've discovered that the "Server" Windows service is not starting on bootup for some reason. When attempting manual start, we get "error 2001: specified driver is invalid."

  • ESXi 5.1 on Poweredge 510 freezes after base-esx update

    - by goober
    Background / Problem Just experienced an issue where an ESXi host was upgraded from 5.0 -- 5.1 perfectly fine. Then, I did a scan and remediated a patch (ESXi510-201210401-BG) Looking into the host on via the kvm switch, this appears to complete successfully. However, on reboot, the server hangs at the "Initializing Power Management" phase. I've read from various spots around the internet that this usually clears itself up again upon a cold boot, but given that our servers are in a different building with different access rules, the less I have to physically go there, the better. :) Question Is there anything I can do to avoid an ESXi host hanging at the "initialize power management" phase of boot after remediating the host to apply patches?

  • Cannot use apt-get/dpkg -- Input/output error

    - by mecho
    I have bumped into an issue that doesn't allow me to do anything related to apt-get: install, remove, etc. Whenever I try to do something (e.g. sudo apt-get install firefox -f) it gives me the same error message: Reading database ... dpkg: unrecoverable fatal error, aborting: unable to open files list file for package `fontconfig-config': Input/output error E: Sub-process /usr/bin/dpkg returned an error code (2) I have tried to deal with the package `fontconfig-config' without success. I have found that the "Input/output error" is usually linked with physical problems of the hd, but I do not think that's the case I am using that hd without any other problem. I have tried removing the mention to the package in /var/lib/dpkg/status as mentioned here. I have tried deleting all files related to the package in /var/lib/dpkg/info as I found somewhere. But I still cannot do anything. The funny bit comes when I look for the file that is giving me troubles: mecho@Ansible-MS-7680:/var/lib/dpkg/info$ ls fontconfig* ls: cannot access fontconfig-config.list: Input/output error fontconfig.list fontconfig.postinst fontconfig.preinst fontconfig.triggers fontconfig.md5sums fontconfig.postrm fontconfig.prerm This is done after I deleted all files ... it looks like fontconfig-config.list still exists but it doesn't show up! Any idea about how to solve the problem? I am on kubuntu precise, fontconfig-config_2.8.0-3ubuntu9.1

  • Windows 7 "Not Responding"

    - by sizeight
    At my office we've got 2 Dell XPS M1530 laptops. Both have been running up to date installations of Windows 7 with NOD 32 Anti Virus for months now with no problems. Last week however both started freezing with "Not responding" issues every few minutes when browsing the web. It doesn't matter which browser, the latest versions of Firefox, Chrome and IE8 all do the same. After a few minutes the browser "wakes up again" but freezes again very soon. I suspect it's an OS update issue, a driver/OS conflict or something. Anybody got a solution for this?

  • PHP 5.4 Support: Minor Features

    - by Ondrej Brejla
    Hi all! This weak is another PHP weak. Asking why? PHP migrates to Git and GitHub! Isn't that cool? And this week is also NetBeans for PHP week, because we have some new NetBeans 7.2 features for you. Note: All PHP 5.4 features are available in your projects after setting Project Properties -> Sources -> PHP Version to PHP 5.4 value, or after choosing the same value during a PHP Project creation (in New Project Wizard). Callable type hint Let's start with a new PHP 5.4 type hint - callable. It's now in code completion and you can use it in your function declarations! Binary notation for integers The next feature is about recognizing of a new binary notation for integers, so you can use it without any problem - no syntax error will occur. Class::{expr}() And the last feature is about using of Class::{expr}() invocation. It's supported by our parser too, so no syntax errors will occur either. That's all for today and as usual, please test it and if you find something strange, don't hesitate to file a new issue (component php, subcomponent Editor). Thanks.

  • MVVM - child windows and data contexts

    - by GlenH7
    Should a child window have it's own data context (View-Model) or use the data context of the parent? More broadly, should each View have its own View-Model? Are there are any rules to guide making that decision? What if the various View-Models will be accessing the same Model? I haven't been able to find any consistent guidance on my question. The MS definition of MVVM appears to be silent on child windows. For one example, I have created a warning message notification View. It really didn't need a data context since it was passed the message to display. But if I needed to fancy it up a bit, I would have tapped the parent's data context. I have run into another scenario that needs a child window and is more complicated than the notification box. The parent's View-Model is already getting cluttered, so I had planned on generating a dedicated VM for the child window. But I can't find any guidance on whether this is a good idea or what the potential consequences may be. FWIW, I happen to be working in Silverlight, but I don't know that this question is strictly a Silverlight issue.

  • Samba permissions on a Debian server with Fedora client

    - by norova
    I have a Debian server sharing files via Samba. I can access the files via Windows with no problems whatsoever, but when I try to mount the share on a Fedora client using the same credentials I am unable to write to any files. I have proper read access, but no write permissions. Here are the settings for the share from my smb.conf: [lampp] path = /opt/lampp writable = yes browsable = yes I have to assume that it is an issue on the Fedora side of things because accessing the share from Windows works fine. I have also tried mounting via SSHFS with no luck; it also will allow me to read files but not write. However, in Windows, using a program called WebDrive I am able to access the files (essentially via SSHFS) with no issues whatsoever. I have tried setting up NFS but not much luck there either; I'd rather just stick with Samba if possible. Any suggestions?

  • Ugly/Inconsistent Theming in Ubuntu Gnome 12.10

    - by Erland
    Some applications are displaying really ugly widgets and menus. I think it's a GTK issue and perhaps more particularly, only applies to GTK2 apps but I'm not sure. The numerous questions on here that deal with GTK2 v GTK3 themes do not answer my problem. Here is my situation: I'm using Ubuntu Gnome with Gnome Shell (installed using the "upgrade" instructions, rather than fresh install) with the default Adwaita theme The reason I did an upgrade instead of fresh install is because I'm on a Macbook Air and there is no mac image/iso for Ubuntu Gnome Previously, I did a fresh install of Ubuntu Gnome 12.10 and had no theming problems Now, apps like nautilus, rhythmbox, brasero, even third-party ones like Lightread look exactly as expected but other apps, including Firefox, Inkscape, GIMP, Libreoffice look awful. Some examples: Firefox with ugly location bar: http://ubuntuone.com/3e2X0JTa4CT4afC4303U9c vs nautilus location bar: http://ubuntuone.com/3TbHWWuNMcJnlpI4IpjiUO GIMP file dialogue (like Windows 95!): http://ubuntuone.com/4ioCcqq3flgO7zAWgAhfWy vs the rhythmbox file dialogue (correct): http://ubuntuone.com/2xLplCOBvQnyeqdsTGdgXq Menus in Libreoffice (very bad for usability): http://ubuntuone.com/26WTaEz4PMGmiItGeSmBjZ vs menus in rhythmbox: http://ubuntuone.com/4Ib4thMLqohsle6J5KEvuI I've been searching for a solution to this problem for some time. The logical explanation is that all the GTK3 apps are working and anything that is still using GTK2 is not. If that's the case though, why did the same installation (Ubuntu Gnome 12.10) and the same theme (Adwaita) previously work with all those GTK2 apps? Desperate for help!

  • Resize Ubuntu Linux system to smaller disk inside VMware ESXi

    - by mlambie
    I have several Ubuntu Linux virtual machines running on VMware ESXi hosts that have all been allocated disks much larger than their required capacity. As space is now becoming an issue on our SAN, I'd like to investigate downsizing the allocated disk space on these machines. All systems will be completely backed up imaged before I begin making changes, and I will always retain a pristine backup in case the partition resizing does not work. Is there an easier way than the following procedure, or is their a better solution entirely? Shutdown and assign a second disk to the virtual machine Boot using the SystemRescueCD Use GParted to resize the original (source) partition, making it smaller Clone the new, smaller partition to the second disk Shutdown and remove initial disk from the virtual machine Reboot and force fsck to check the filesystem

  • How old is "too old"?

    - by Dori
    I've been told that to be taken seriously as a job applicant, I should drop years of relevant experience off my résumé, remove the year I got my degree, or both. Or not even bother applying, because no one wants to hire programmers older than them.1 Or that I should found a company, not because I want to, or because I have a product I care about, but because that way I can get a job if/when my company is acquired. Or that I should focus more on management jobs (which I've successfully done in the past) because… well, they couldn't really explain this one, except the implication was that over a certain age you're a loser if you're still writing code. But I like writing code. Have you seen this? Is this only a local (Northern California) issue? If you've ever hired programmers:2 Of the résumés you've received, how old was the eldest applicant? What was the age of the oldest person you've interviewed? How old (when hired) was the oldest person you hired? How old is "too old" to employed as a programmer? 1 I'm assuming all applicants have equivalent applicable experience. This isn't about someone with three decades of COBOL applying for a Java guru job. 2 Yes, I know that (at least in the US) you aren't supposed to ask how old an applicant is. In my experience, though, you can get a general idea from a résumé.

  • unable to run OpenOffice from text mode

  • Should a link validator report 302 redirects as broken links?

    - by Kevin Vermeer
    A while ago, sparkfun.com changed their URL structure from /commerce/product_info.php?products_id=9266 to /products/9266 This is nice, right? We don't need to know that it is (or was) a PHP page, and commerce, product_info, and products_id all tell us that we're looking at some products. The latter form seems like a great improvement. However, the change would have broken existing links. So, nicely, they stuck in 302 redirects. Visit http://www.sparkfun.com/commerce/product_info.php?products_id=9266 and your browser will issue GET /commerce/product_info.php?products_id=9266 HTTP/1.1 to which Sparkfun's servers reply HTTP/1.1 302 Found Location: http://www.sparkfun.com/products/9266 This 302 redirect is caught by Stack Exchange's link validator as a broken link. It's not broken it works just fine. Here, try it: http://www.sparkfun.com/commerce/product_info.php?products_id=9266 I understand that a 302 redirect is intended to be a temporary redirect, while a 301 should be used for permanent changes per RFC 2616. That said, Wikipedia and common practice use it as a redirect. Who is in error in this situation? Is this an error in Sparkfun's redirect implementation or in Stack Exchange's URL validator?

  • Why does my game loop speed vary on different platforms with the same hardware?

    - by Sri Harsha Chilakapati
    I've got a serious issue with my game loop. This loop varies in time with the platform and with the same hardware. This is a list of FPS achieved: - Windows ======= 140 to 150 - Linux ======= 120 to 125 - Windows(WINE) ======= 125 to 135 And since my game loop is fixed timestep, the speed of the game is not stable. Here's my game loop. public final void run() { // Initialize the resources Map.initMap(); initResources(); // Start the timer GTimer.startTimer(); GTimer.refresh(); long elapsedTime = 0; // The game loop while (running) { // Update the game update(elapsedTime); if (state == GameState.GAME_PLAYING) { Map.updateObjects(elapsedTime); } // Show or hide the cursor if (Global.HIDE_CURSOR) { setCursor(GInput.INVISIBLE_CURSOR); } else { setCursor(Cursor.getDefaultCursor()); } // Repaint the game and sync repaint(); elapsedTime = GTimer.sync(); Toolkit.getDefaultToolkit().sync(); } } The timer package How could I improve it?

  • Aptana Ext code completion in .php files

    - by Frederik Wordenskjold
    I'm having problems getting the code-completion for the Ext 3.2 plugin to work, when working with .php files. I've also installed the php plugin for Aptana, and the same thing applies for php - I cannot access php code-completion when working with a html-file, so it seems like a general issue... It's also not possible to write Ext in .js files, which is weird... The latter case does make sense of course. But I should be able to write both php and Ext in .php files! Is this possible in any way? I have of course tested the code-completion for php in a .php file, which works. The same applies for Ext code in .html documents!

  • MacBook Pro - 72k vs 54k rpm drives - Heat and Noise

    - by webworm
    I am looking at a new 15" MacBook Pro for development purposes. I am planning to run a Virtual Machine for about 50% of my work (Windows 7 x64, IIS, SQL Server, and VS 2010). The upgrade from a 54000 rpm drive to a 72000 rpm is only $45. From what I understand the faster rotational speed of the 72000 rpm drive will help virtual machine performance. However, I am concerned that additional heat and fan noise might be an issue. I will be running mostly on A/C power so decreased battery life is not a major concern for me. Since I would be running with a Core i7 processor which gives off a fair amount of heat already I was wondering if it might be best to stay at 54000 rpm for the hard drive. What do you all think? Thanks!
