• Determine the architecture of a Mac from the command line or script?

  - by Brian Postow

  I'm writing a shell script, and I need to know the archetecture, ie PPC or Intel. Back in the day, there was a program /bin/arch that told you, but my mac doesn't seem to have it... Is there an easy way I can do this? Grep for something in a logfile? call some other program that spits that out as a side effect? It would be nice to know what OS Version I'm running too, but that may not be necessary. thanks

• Operating system not found after downloading skin pack

  - by 8BitSensei

  My brother has downloaded a executable file from Skin Pack — I believe it was the Mountain Lion IO6 skin pack. He's using an Acer Aspire 553G. And now his operating system won't start (Windows 7). It gets to the BIOS and then goes to load up the OS but the screen goes blank and it just goes back to the BIOS over and over again. He decided to play with the bootup settings and tried different options and got the error message "Operating System not found." Does anyone have any idea how to solve this?

• how can I get rid of duplicate administrators on 2 macbook pro's

  - by BCITY

  I got a new MacBook Pro (insurance payout) and passed my old one (previous generation MacBookPro 2008) on to a staff member whose MacBook Pro died. I used carbon copy to move my data to the new laptop but couldn't do the same with her move as the older Macbook wouldn't allow it as it was on an old OS. Ended up just migrating her software onto my old MBP. Now however, they both have the same admin identities and her computer is synching with my mobile me account. Can I change the administrator identity and save all her applications? I am hoping that I don't have to wipe and reinstall everything to change her computers identity.

• Cross-platform centralized desktop password manager

  - by Dave

  I have been using KeePass as a desktop password manager on Windows for many years. Love it! However, I am now needing to work on different platforms much of my day (Windows 7, Windows XP, Mac OS X, Ubuntu, and OpenSUSE.) I'm looking for a password manager I can share across all these platforms. My ideal solution would: Run natively (not in a virtual machine) on all platforms. Store the "official" copy of the password data on a local network so I can get to it from any and all machines. It is OK if it locks (or becomes read-only) when one client is accessing it. Keep a local cached copy (read-only is fine) so I can still get to my passwords when disconnected from the network. Does any such beast exist?

• VMWare Lab Manager: What's the best way to build Library Configurations?

  - by mcohen75

  We're using Lab Manager within our QA group. We use it to quickly deliver environments we need for testing. We have 25 Templates, 14 Library Configurations and counting. To build up our templates we: Create a base template that is a bare bones version of Server 2008 + basic configuration (Windows Update, Firewall exceptions) Create a linked clone for each Server template we need (SQL Server 08, 05, etc) Repeat for other OS's, like Windows 7 and Windows XP Then we create configurations: Create a workspace configuration with multiple images in it (Say Server 08 w/SQL Server and Windows 7) Deploy the configuration and make some minor configuration changes Undeploy and Capture to Library How do we keep this manageable? When I need to update a configuration, should I: Rebuild it from templates Clone it to a workspace, make changes, recapture it to the library keep the configuration in my workspace (don't delete it after capturing it to library), deploy it to make changes and then re-capture to library

• Game programming : C# or C++?

  - by Chronix

  Ok so the faq says : "What language should I learn next? (Unless you have a specific requirement and don't know which language meets that requirement.)" so I guess this is not against the rules of questions. So, I've decided what I really want is to do Game Programming. So the question is, as a 18 years old who wants to learn self taught programming, what is the most suited programming language between C# and C++? ( I should state that I don't care about unix because I believe windows will be still the most used os ) I know the basics of C++, but none about C#. I know that C++ has more tutorials guides, dlls and stuff like that, while C# doesn't, but it's far easier to learn and to use for a single person to develop a program, but I've read even if the program is obfuscated it's easy to get the source of it. Well, I kinda want to focus on basic a lot first, I must say that I have a preference for C++ just because it feels more suitable to me, but I must consider that I work alone.. So even if I like it, it may not be the best thing to do. I am really not sure of which one to go for, i've read a lot of threads on various websites and it looks like C# is becoming more popular than C++. But yeah, that said, I also specified I want to do Game Programming. So I need to know some better points than just "C# is easier because of .net memory handling while C++ isnt" because I couldn't just find it. I hope the thread won't be closed because I've read the faq and I have a specific requirement. Thank you, and if you need more details you're free to ask me, but I think just by saying game programming and that I'd work alone should be enough!

• Block Websites at Work

  - by user791022

  At work there are about 40 PCs. I want to block all the websites and only allow a few Domains/Websites for operators. A few operators can access anything. I want something quick and easy so I can filter the Block/Allow websites for all computers from one main computer, like a server or something. Windows Vista Home and Windows 7 Home are installed on the PCs. Is there any software can do this? PS: Please don't answer about Microsoft Windows Server OS..

• Is there a (free or commercial) print server which print PDFs from networks?

  - by Eonil

  I'm working in office which uses Windows server for printing. Because our printer supports only Windows driver. But here are Mac OS X also which requires network printing... I'm sure there is no driver of the printer for Mac. So I figured out an idea to do this. On the Mac, a virtual printer driver generates and sends PDF file to print server. Print server, prints PDF files with it's local printer. Is there a solution can do this? (free or commercial)

• Is UEFI more or less vulnerable than Legacy BIOS?

  - by Eric

  Is UEFI more secure than BIOS on a Windows 8.1 machine? Is UEFI vulnerable to malware in ways that Legacy BIOS is not? Is it correct that UEFI can connect to the internet before the OS (or anti-virus program) has loaded? On some boards, UEFI settings can be changed in Windows. Do these things affect PC security? I have read that BIOS on an MBR disc can be vulnerable to 'rootkits' There have been reports that suggest UEFI secure boot may not be infallible. Is UEFI better at defending against malware than BIOS?

• Snapshot/Save GPU Drivers

  - by ashes999

  Since I'm running XP/32-bit, my GPU drivers are quite fragile. I've spent several hours trying to back up and restore from old versions, on at least two separate occasions. Writing down the device drivers is not enough. In the short term, I would like to somehow save, zip, backup, snapshot, or something so that if I need to reinstall my OS in the short-term, I have a reliable way to get the drivers. ATI's website doesn't have the install kit anymore, and I don't have it saved; I googled, but didn't find the exact same version. How can I backup/save my drivers so that I can reinstall them later?

These urls are available two the users using these and other applications Now I want to hide the ports on which each of the applications are running... So that the user could see only something like this http://10.XXX.XXX.XXX/myAPP1 http://10.XXX.XXX.XXX/myAPP2 http://10.XXX.XXX.XXX/myAPP3 What is needed to be done for this I have achieved this for one url (i.e. one port) using the firewall rules and redirect the request on HTTP 80 port to the port that tomcat is listening.. But I want such patter to appear for all the urls... How can I go about this? Specs HOST M/C : 64 bit OS: Linux Redhat Tomcat : 6.0

• Game 30% done on HTML5. Maybe it was a bad idea. Should I change to Unity3d? [on hold]

  - by Dokkat

  I'm creating a 3d game on HTML5. It's 30% complete and the hard part is already coded. The server is on node.js.Now I'm realizing that maybe it was not a wise choice. This is because I realized: Three.js still has many bugs. I don't see the same thing on every machine. Each browser, OS, can give different results. I'm afraid my clients will have a great stress installing my game properly. I have tons of sprites and models on my game. I wonder if my clients will have to load all them again everytime they want to play? I wonder if a Node.js server will be fast enough to handle it, and I'm afraid it won't be scalable. What would you advise me? Should I continue and finish the game on HTML5 or is it better to remake it on something else, like Unity3d for the client and (what?) for the server?

• Hyper-v dynamic memory client machines always use maximum memory

  - by Eric P

  When I create a virtual machine in Hyper-V and set it up to use dynamic memory, the virtual machine will always use the maximum memory within the virtualized OS. Hyper-V will show the assigned memory at 514mb, but when I log into the server and pull up task manager, it will show 90% memory used. When I bump the maximum memory up to 4gb, I get the same result: 90% memory usage. Nothing is even running on the virtual machine other than a clean instal of Windows Server 2008 R2. I have also tried it with Windows 7 with the same results. Is this the expected behavior or is something setup wrong

• X11 not sending windows to remote computer matlab

  - by MZimmerman6

  I am trying to set up my home desktop, running OS X Mountain Lion, to basically do a bunch of grunt work for me remotely. I have set up ssh, and am able to remotely control the computer fine, but the issue comes in when I try to run X11 apps, like MATLAB, remotely and get windows to pop up. Every time I try to bring up a new window it either opens that window on the remote computer (not the one I am using to control it), or it tells me it can't find a display. here is how I am setting up my ssh assume my matlab alias is set up properly, which it is. ssh -X [email protected] matlab -nodesktop figure; This will open the window on the computer I am SSHing into, and not on the remote one. Basically I want that window to open on the computer I am remoting from. I changed my SSH X11Forwarding and stuff to be yes in ssh_config and sshd_config. Any other suggestions?

• dual-boot does not work

  - by elyashiv

  I have a PC with linux-mint installed on it. I wanted to install win-7 along-side, for some reasones. what I have done is: create a bootable USB-stick with Ubontu ios. restarted the computer, this time with Ubuntu (running from my disk-on-key). created a partition on the main HD using GPart. formated the partition to NTFS. restarted the computer, this time through the installation CD for win-7. installed win-7 with normal settings. that all worked, and I'm writing this through win-7. the thing is - when I boot my system, I don't get to choose what OS to run. I checked the settings in msconfig, and in boot label it has just win-7. how can I boot linux?

• I have to manually enter the pwd when I login at school and when I come back home with my laptop (DELL E6410)

  - by Bong Paduano

  I didn't have to do this the first 3 months of me going to school. My laptop used to be able to connect to my Home WiFi and school Wifi automatically then after the 3rd month something changed and eversince then I literally have to manually enter each of the Wifi passwords in each location each time I try to connect to their respective WLAN. I tried adding each WiFi networks in the "Manage wireless networks" section in the Network and Sharing Center but everytime I login to one of the location, the created network disappears and I did this more than once. I tried restoring the OS back but to no avail. Can someone please assist me on this issue. I'm not sure if this issue has been addressed in this website but I haven't seen any similar question in here. I appreciate any help anyone may be able to share.

• Is it possible to change User's Home Directorys permission in OSX?

  - by Sosiska

  Most of your staff uses OSX as main operation system. The problem is that recently we were attacked with some odd malware: users are getting zip-file via mail, and when they open this zip file, they execute a binary keylogger malware, that is inside this zipped file. (One click is enough). We have some non-technical limitations and due this limitation we can't configure user's mail servers. But actually we have physical access to their laptops. As far as I know, there is possible to mount user's home directory without "x" (execution) permission in Linux and *BSD. So users can't run some binary file inside home directory. Is it possible to configure OS X so that user can't execute files inside /Users/?

• Mac | Router not assigning the IP address.

  - by Vaibhav Bajpai

  I recently installed Mac OS X 10.6, however the ethernet state is down. The assigned IP is 169.x.x.x. When booted the live USB of Ubuntu, I properly get an IP assigned in the range 192.168.1.x from the router 192.168.1.1 I am using the same router and same ethernet line. I tried to ping to 192.168.1.1 from my Mac and I get a host down message. I tried to manually assign the IP and set the router IP to 192.168.1.1 but still the router is unreachable.

• Is there a Google Authenticator desktop client?

  - by cwd

  I am using Google Authenticator for 2-step authentication. I like how I can use a code and verify my account using my phone: I realize that the app was designed to run on a device other than a computer to increase security for the computer (in case that it is lost or stolen), but I would like to know if there is a way I can run Google Authenticator on my Macbook. Now, per the Google Authenticator Page it will not run on a desktop: What devices does Google Authenticator work on? Android version 2.1 or later BlackBerry OS 4.5 - 6.0 iPhone iOS 3.1.3 or later However there are several emulators for developers and so I wonder if it is possible to run one of these emulators and then run Google Authenticator with that. I do realize this is not a best practice - but I'm less worried about my laptop getting stolen and more worried about someone just hacking the account. So my question is this: Is it possible to run it on the desktop, even though it is not meant to be / not recommended?
