• Mac server default file permissions

  - by Bobby Jack

  How do I change the default file permissions for files created on a Mac server? In case it's relevant, this is a Mac Mini running Mac OS 10.6.7. It's currently used mainly as a file server, and there are several users who need to share files. These files need to be writable by all, rather than the default which is writable only by the owner. I've been trying to do something with umask and a startup script, but I'm not sure there's a startup script that will apply to connections via Finder. I also need this to apply to files created on a client (also Macs) and copied onto the server.

• How to Change and Manually Start and Stop Automatic Maintenance in Windows 8

  - by Lori Kaufman

  Windows 8 has a new feature that allows you to automatically run scheduled daily maintenance on your computer. These maintenance tasks run in the background and include security updating and scanning, Windows software updates, disk defragmentation, system diagnostics, among other tasks. We’ve previously shown you how to automate maintenance in Windows 7, Vista, and XP. Windows 8 maintenance is automatic by default and the performance and energy efficiency has been improved over Windows 7. The program for Windows 8 automatic maintenance is called MSchedExe.exe and it is located in the C:\Windows\System32 directory. We will show you how you can change the automatic maintenance settings in Windows 8 and how you can start and stop the maintenance manually. NOTE: It seems that you cannot turn off the automatic maintenance in Windows 8. You can only change the settings and start and stop it manually. Can Dust Actually Damage My Computer?

• Laptop screen brightness stuck

  - by Bart van Heukelom

  I can no longer adjust the brightness of my laptop screen, it's stuck at the lowest. In Linux, the brightness adjustment keys (Fn + F4/F5) still work, since a brightness popup shows and the meter bar changes, but it does this in a strange way. Starting at 100%, each successive press of the "lower brightness" button moves the bar to: 67% 50% 0% 26% 12% Or another random pattern like that. The problem is not Linux however, since I can't change the brightness from Windows (7) either. Where do I even begin to look? Since the problem does not seem be OS-specific, I've searched in the BIOS, but it has no option like that. How did this happen? I think it's been this way since when I lowered the brightness to 0%, then pressed the "lower brightness" key again. Not sure about that though.

• How can one unlock a fully encrypted Ubuntu 11.10 system over SSH at boot?

  - by Jeff

  In previous versions of Ubuntu, and current versions of Debian, you can unlock a fully encrypted system (using dmcrypt and LUKS) at boot time over SSH. It was as easy as: Installing the encrypted system using the Ubuntu alternate installer disk or normal Debian installer disk and choosing to encrypt the system. After the system is installed, adding the dropbear and busybox packages. Updating the initram-fs to authorize your ssh key. At boot time, you'd just ssh to the machine, and do: echo -ne "keyphrase" > /lib/cryptsetup/passfifo The machine would then unlock and boot the encrypted system. Using the exact same steps on Ubuntu 11.10, I can ssh to the machine, but /lib/cryptsetup/passfifo doesn't exist. There appears to be no way to unlock the system over ssh. I'm not sure where to look to see if this functionality changed or if it was removed.

• Trouble switching to Dvorak on Ubuntu 12.04

  - by Dodgie

  I've decided to switch to Dvorak on my Ubuntu machine, but I'm having some trouble: First, I attempted to do this through the GUI -- System Settings - Keyboard Layout - add layout (plus sign) - English(programmer Dvorak). This didn't work at first, so I restarted my machine. It seemed to work at the password prompt (if only because QWERTY did not), but I couldn't get it to accept my password. I used the virtual keyboard option to enter my password with mouse clicks (the virtual keyboard was using the programmer's Dvorak Standard) and was able to get in that way. Once logged in, however, I was back to QWERTY. Second, I tried to switch on the command prompt -- $ loadkeys /usr/lib/kbd/keytables/dvorak.map The error message I received was "Couldn't get a file descriptor referring to the console " Does anyone know what I'm doing wrong? I've looked for a solution for these problems, but couldn't find anything.

• How can I build the best Cyber Cafe possible using Ubuntu (Desktop or the Server Edition)?

  - by Osman Hassan

  My question has to do with my plan/dream of opening a Cyber Cafe in Mogadishu, Somalia, my birth place. I plan to use 5 to 15 computers (all laptops) running Ubuntu. Now that you have the background to my question, I need your help, advice and expertise. What type of computer (laptop) should I use for this project? What type of operating system (Ubuntu Desktop/Ubuntu Server Edition) should I use? How can I setup a file and printer sharing server? What program should I use to manage the client computers? If you have done this before and can point me to the best and easiest way to build this Cyber Cafe, I would appreciate it tremendously. Also, if you can point me to any books, articles, or blogs which I should read, I would appreciate it too.

• Resources for understanding iOS architecture [closed]

  - by BlackJack

  I recently finished reading Randall Hyde's excellent book Write Great Code: Volume 1: Understanding the Machine, and I have a much better knowledge of what's going on under the hood now. I want to start making iPhone apps, and there are lots of guides for that. Embracing my inner Hyde, however, I want to first learn about the iOS system architecture. Apple has a really good overview here: iOS Technology Overview Before I start, I wanted to know if there were any other good resources for understanding iOS architecture and using that knowledge for iPhone programming. Thanks.

• What are the pros and cons about developing under MAC OS? [closed]

  - by user827992

  Sometimes i get the chance to program under MAC OS, i knew about this OS since Apple shipped its computers with a PowerPC by Motorola ( since Panther, more or less ), these days they are all X86 and i see no particular advantages about adopting this platform, also i see only downsides for the main part, i do not want to cause flames, please reply if you have a good answer or you can contribute in some constructive way. I'm trying to write a list of the natively supported languages, or the languages that comes only under MAC OS with some particular technology, my list is this: Objective C with Cocoa/Carbon I'm not considering personal preferences here, if a person X likes to code under Xcode it's probably ok to have a MAC, if a person Y likes to code under Visual Studio it's probably ok to not having a MAC, my purpose is to clarify what MAC OS is good for. I also do not get why people glorify the MAC for historical reasons, I mean a language like Java just comes for MAC only in the 7th edition of its JDK, things like GCC are just a porting and many technologies are out of the question like C# ( I'm sorry, i do not consider MonoDevelop like a serious alternative ) , .Net, ASP, DirectX, and many others are just, again, porting or free software, like PHP, MySQL, Javascript, XML, CSS, OpenGL, etc etc. My question is: what is so special about being a programmer under MAC OS? There is something that I have not seen? I also noticed that a significant portion of MAC users end up using their MAC like a normal Windows PC with Parallels or something like that. I can afford to buy a MAC, show me why this machine is so unique.

• HD Video on Pandaboard ES

  - by Lord Loh.

  I am running Ubuntu 11.10 on my Pandaboard ES. I attempted to playback a 720p / 1080p video. In both cases, the videos were highly jittery and the audio seemed to be plagued with something that seemed to be white noise (sounds like white noise, but it definitely is not white noise). I was using VLC media player for playback and was running XFCE4 as the desktop ewnvironment. The system monitor graph indicates both the CPU cores running ~100%. Lower resolution videos seemed to play without problems. How do I play 1080 / 720 HD videos on pandaboard? Thanks in advance.

• Freezes for unknown reasons, causing fan to go crazy on a Portege laptop

  - by Sünnje

  I have recently installed Natty on a new Toshiba Portege laptop. I find it extremely irritating that the system freezes frequently, about every other time I use the computer. Then the fan goes crazy and I have to force-shutdown. It seems to happen no matter what I do; I encountered this problem when using Firefox, LibreOffice, Adobe Reader - probably when using only terminals too, but I'm not certain. It may be fan-related, because the computer seems to get heated up compared compared to earlier, but I am not sure about that. Any ideas why this could be happening?

• Logic in Entity Components Systems

  - by aaron

  I'm making a game that uses an Entity/Component architecture basically a port of Artemis's framework to c++,the problem arises when I try to make a PlayerControllerComponent, my original idea was this. class PlayerControllerComponent: Component { public: virtual void update() = 0; }; class FpsPlayerControllerComponent: PlayerControllerComponent { public: void update() { //handle input } }; and have a system that updates PlayerControllerComponents, but I found out that the artemis framework does not look at sub-classes the way I thought it would. So all in all my question here is should I make the framework aware of subclasses or should I add a new Component like object that is used for logic.

• The case against INFORMATION_SCHEMA views

  - by AaronBertrand

  In SQL Server 2000, INFORMATION_SCHEMA was the way I derived all of my metadata information - table names, procedure names, column names and data types, relationships... the list goes on and on. I used the system tables like sysindexes from time to time, but I tried to stay away from them when I could. In SQL Server 2005, this all changed with the introduction of catalog views. For one thing, they're a lot easier to type. sys.tables vs. INFORMATION_SCHEMA.TABLES? Come on; no contest there - even...(read more)

• Ubuntu Suspend won't wake by mouse

  - by corsen

  I just installed Ubuntu 11.04 and realized that suspend would not wake by either keyboard or mouse. After following instructions from here: http://ubuntuforums.org/showthread.php?t=1642817 The system will now wake by keyboard. I have a USB mouse it is a logitech G5. Even if I enable all of the USB devices listed in /proc/acpi/wakeup, my computer will still not wake up via mouse. I'd really prefer to wake by mouse instead of keyboard due to cats. Does anyone know why my mouse won't wake the machine even after enabling all USB devices listed? Thanks, Bryan

• Font Book does not Install all Fonts

  - by waiwai933

  My Mac decided to delete all but 19 fonts, which is fairly annoying. It didn't really delete them, as in I still have the original files in the /Library/Fonts folder, but they've disappeared from Font Book, so I can't use them. Now, Apple says that you can select a folder to install all fonts in that folder, but when I try that, the spinning wheel (not the beach ball) comes up in the lower right hand corner for a few seconds and then leaves, without installing any fonts. The same thing happens if I use the + sign in the menu bar, select multiple, or if I try validating and then installing (actually, that installs one font). Is there any way to mass-install these fonts or will I have to install them one by one? Comp info: Mac OS X 10.5.8 running Font Book 2.1 (123).

• Permission Mystery - apt-get and other system utilities have 000 permissions

  - by emteh

  I'm trying to track down this strange behavoir for years now. Always after installing software-updates the permissions of a lot of system-tools are broken as you can see below. I am reasonable convinced that the machine is not owned by someone else. Regular security updates + grsecurity kernel + pax + daily rkhunter runs. Besides that there is no incentive for an attacker to fiddle in such obvious ways with the system. I installed bastille linux (http://bastille-linux.sourceforge.net/) und tried to deinstall it later, so the problems could be related to that. However I don't see how this can happen in a regular way after updates. System: Ubuntu 10.04, recently updated to Ubuntu 12.04 but the problem persists. Apt-Configuration in /etc/apt/ looks sane to me. But nevertheless - could here be the source of the trouble? DPkg::Pre-Install-Pkgs {"/usr/sbin/dpkg-preconfigure --apt || true";}; DPkg::Post-Invoke { "if [ -x /usr/bin/debsums ]; then /usr/bin/debsums -- generate=nocheck -sp /var/cache/apt/archives; fi"; }; // Makes sure that rkhunter file properties database is updated // after each remove or install only APT_AUTOGEN is enabled DPkg::Post-Invoke { "if [ -x /usr/bin/rkhunter ] && grep -qiE '^APT_AUTOGEN=.? (true|yes)' /etc/default/rkhunter; then /usr/share/rkhunter/scripts/rkhupd.sh; fi" } DPkg::Post-Invoke {"if [ -d /var/lib/update-notifier ]; then touch /var/lib/update- notifier/dpkg-run-stamp; fi; if [ -e /var/lib/update-notifier/updates-available ]; then echo > /var/lib/update-notifier/updates-available; fi "; }; Where do these chmod 000 come from?

• "Unable to install GRUB in /dev/sda" when installing GRUB

  - by vicban3d

  I recently bought a shiny new Lenovo Yoga 2 Pro and I want to dual boot it with Ubuntu for studying purposes. Its built-in OS is Windows 8.1 and it has a 256GB SSD. I've made a separate 90GB partition just for Ubuntu and a live USB to install it. The first time everything seemed to work great, I solved the wifi issued by blacklisting ideapad_laptop, the installation went flawlessly and Ubuntu worked fine. When I got up the next morning and turned on my laptop it booted into Windows right away without ever showing the GRUB menu. So I tried to reset, and checked my partitions with the Disk Manager and everything looked fine. Since I couldn't find a solution online I went ahead and formatted the partition to try and install again. This time and every time since, the installation was aborted and I got a fatal error saying: Unable to install GRUB in /dev/sda Executing `grub-install /dev/sda` failed. This is a fatal error. Can anyone please suggest a solution to this problem? If any further information is needed I would be happy to provide it. Thanks. When installing I get the following in details: ubuntu kernel: [ 1946.372741] FAT-fs (sda2): error, fat_get_cluster: invalid cluster chain (i_pos 0). ubuntu grub-installer: error: Running 'grub-install --force failed.
