• Best filesystem for an external drive? ExFAT?

  - by GiH

  What is the best filesystem for use with multiple OS's? I saw this question but its old and doesn't take into account ExFAT. Here is what I know from my findings: NTFS - Can't write from Mac FAT32 - Doesn't support files larger than 4GB HFS - Only mac ExFAT - ??? I don't know much about this but it seems like it got rid of the 4GB limit of FAT32 and can be read on Windows, Mac, and Linux. Is ExFAT the best bet? I tried formatting the drive in ExFAT just now, but on Windows XP SP3 it was showing up as not formatted... It seems to me like FAT32 is still the best, but I wanted to see what other people had to say.

• How to Create Shortcuts to Programs on USB Drives

  - by Lori Kaufman

  If you work on multiple computers, you probably use a USB drive to take your favorite portable software with you. Portable application suites like PortableApps.com, CodySafe, or Lupo PenSuite, each have a main menu providing access to the programs installed into the suite. However, there may be reasons why you need to create shortcuts to programs on your USB drive. You may be using a program that does not integrate into the suite’s main menu. Or, you may not be using an official portable application suite at all, and just placing portable software in a folder on your USB drive. Maybe you prefer using shortcuts on the root of the USB drive, like a portable desktop. Whatever your reason, you can’t just create a shortcut to an application on the USB drive and place it in the root of the drive. The shortcut will always refer to the full path of the application, including the drive letter. Different computers assign different drive letters to USB flash drives, so you would have to change the drive letter for your shortcuts when it changes. You can assign a static drive letter to the USB drive. However, if you would rather not do that, there is a way to create shortcuts to programs on a USB drive using relative paths. Because Windows does not support relative paths in shortcuts, we will show you how to create a “shortcut” on the root of a USB drive by creating a batch (.bat) file and converting it to an executable (.exe) file.

• What would you use to keep track of all the random information about your LAN/Enviroment?

  - by agnul

  Say you work in your average anarchy... no appointed IT guy, no Office-Manager whatsoever, just developers working in free-for-all mode and a couple of non technical people around for admin (non IT) stuff. What would you use to keep track of Hardware / Software inventory Backups of OS images, Drivers, and all that LAN configuration information Passwords for all the systems Currently I'm thinking of having some sort of wiki + web server on our only ''server-class'' machine, but then I fear I'd be the only one who would go through the hassle of adding information in the wiki... So, have you been through that? What would you suggest?

• Is giving read permissions on /etc/shadow to apache user a wise decision from security point of view?

  - by Czar

  I have to use PAM authentication for DAV SVN, but when everything is configured as specified in mod_auth_pam documentation, authentication does not work. After some research I realized, that for this to work, httpd should be running under root user (which I don't like and won't implement) or apache user (under which httpd is running by default) should have permissions to read /etc/shadow file. So there is a pair of questions connected to each other which I want to ask: Is giving this permition to apache user a wise decision from security point of view? If answer to the first question is "yes", what is the correct way to do so? For now I've done following: groupadd shadow usermod -G shadow apache chmod g+r /etc/shadow Another way I can come up with is using acl: setfacl -m u:apache:r /etc/shadow Note: OS is Fedora 14 x86_64 (kernel: 2.6.35.11) httpd v2.2.17 mod_auth_pam v1.1.1

• Chromebook C720 - issue suspending and booting

  - by user72727

  I recently bought an Acer C720 chromebook (Celeron, 2GB RAM, 16GB SSD) with the intention of loading Linux and using it as a cheap development laptop while on my holiday. The installation sort of went ok but initially the trackpad didn't work so I ran a script that mostly fixed that. My current issues are: Booting: it still goes to the chrome "unknown os" white screen - I have to press ctrl L - then escape then 1 then wait for 30 secs while it seems to be searching for something. Then Ubunto loads up fine. Any idea how to fix this? Suspend: if I close the lid of the laptop then it doesn't seem to suspend properly. At least when I open the lid the screen appears to be on but the screen is blank with a cursor. Nothing responds on the keyboard and I have to hold the power down to restart it. The suspend from the top menu has the same issue. Moving windows: I don't have a mouse click button so how do I move windows around the screen? Launcher bar: I've set mine to auto hide (which it does) but what exactly do you have to do to get it back? I just repeatedly jab the mouse at the side of the screen and eventually it pops up. I don't mind starting all over again but obviously a quick fix is preferred ;) Mike Ubunto 14.04.1 LTS Kernel 3.13.0-32-generic PS Sorry for so many questions.

• Configuring permissions with Bastille

  - by Lucio

  I was using Bastille to improve the security of OS and I found the next question there I don't know if I should answer for YES or NOT: Questions: Would you like to set more restrictive permissions on the administration utilities? Explanation: In general, the default file permissions set by most vendors are fairly secure. To make them more secure, though, you can remove non-root user access to some administrator functions. If you choose this option, you'll be changing the permissions on some common system administration utilities so that they're not readable or executable by users other than root. These utilities (which include linuxconf, fsck, ipconfig, runlevel and portmap) are ones that most users could never have a need to access. This option will increase your system security, but there's a chance it will inconvenience your users. My users: When I installed Ubuntu I had create a user (admin), then I was able to create another user (people) but I cannot change the permissions of this user. Questions: The user there I am using like admin it's not the root, right? The effects of this option will affect to the two users (admin & people) or just to people?

• How to de-dupe identical photos that have a slightly different file size?

  - by GJ.

  I imported many photos using the new "camera import" feature of Dropbox. Many of those were duplicates of photos previously imported by direct copying from the camera. Strangely, the Dropbox import appears to slightly reduce the file size. E.g. here on the right is the file imported through Dropbox: Comparison of the two files using pdiff returns "Images are binary identical", but tools such as fdupes or even the Picasa "show duplicate files" feature, consider them as unique. What can be the cause of this file size change? Is there any way to undo it? Most importantly: how can I de-dupe efficiently without regard to file size comparison? (running pdiff comparison over all photo pairs in my library is obviously impractical...) A solution for either OS X or Windows would do.

• Click buttons on the mouse stopped working in 12.10

  - by Kushal

  everything was great for a couple weeks after the upgrade, and then all of a sudden, the click buttons on my trackpad (as well as any other USB mouse I would hook up) stopped working. The pointer moves fine, but the clicks don't work. Sometimes the left click doesn't work but right click does, and then some times, neither works. I noticed this would begin when I would accidentally drag some text in a web browser (you know how when you try to move your pointer through the trackpad, but you accidentally tap down and it starts to drag whatever text you've selected on the window), and then you're done. The clicks won't work after that. They would work upon rebooting or logging off and back on, but then after a few minutes of usage, things would go back to being broken again. It happened a LOT when I was trying to play Scrabble on Facebook. I've raised a bug for this, but I haven't heard back anything on it. Here's the bug report: https://bugs.launchpad.net/bugs/1077805 Since the system was unusable this way, I had to remove it and install another OS based on 12.04. Has anyone else faced this issue or does someone know what to do to fix it? I'd go back to vanilla Ubuntu in a heartbeat if this issue can be fixed.

• Cannot open any web page, but MSN Messenger works

  - by Steven

  I use my computer behind a router. My MSN program can connect to the Internet, but I can not open any web site with my web browser. It seems that this problem is related to DNS because when I input an IP address directly in the address bar of my web browser, the web page can be displayed. However, I don't know how to fix this problem. I choose Google Public DNS server on my computer, this problem still exists. My OS is windows XP. How to fix this problem? Any ideas?

• Is an event loop just a for/while loop with optimized polling?

  - by Alan

  I'm trying to understand what an event loop is. Often the explanation is that in the event loop, you do something until you're notified that an event occurred. You than handle the event and continue doing what you did before. To map the above definition with an example. I have a server which 'listens' in a event loop, and when a socket connection is detected, the data from it gets read and displayed, after which the server goes to the listening it did before. However, this event happening and us getting notified 'just like that' are to much for me to handle. You can say: "It's not 'just like that' you have to register an event listener". But what's an event listener but a function which for some reason isn't returning. Is it in it's own loop, waiting to be notified when an event happens? Should the event listener also register an event listener? Where does it end? Events are a nice abstraction to work with, however just an abstraction. I believe that in the end, polling is unavoidable. Perhaps we are not doing it in our code, but the lower levels (the programming language implementation or the OS) are doing it for us. It basically comes down to the following pseudo code which is running somewhere low enough so it doesn't result in busy waiting: while(True): do stuff check if event has happened (poll) do other stuff This is my understanding of the whole idea, and i would like to hear if this is correct. I am open in accepting that the whole idea is fundamentally wrong, in which case I would like the correct explanation. Best regards

• OS2/Warp - Remotely Stop and Restart a Program

  - by Justin S

  Our current phone system runs off of a legacy OS2/Warp box. Periodically we have to log into the machine and restart OS2RSD.exe and then start it again and the phone system starts working again. The problem is we have to physically get in front of the box and use the GUI to stop and restart the process. Is it possibly to remotely run a script to kill OS2RSD.exe if its running and then start it again? I have been unable to figure this out on my own. The OS is OS2/Warp Version 3 if that helps.

• Why does a redirect from a local IP address assume localhost?

  - by Jeremy

  I am developing a web application on my desktop and it is running on port 80. I am able to access the application from my laptop connected to the LAN by entering my desktop's LAN IP address 192.168.1.8. Now, my application sends a redirect after login, but my laptop assumes the final address is localhost/login. If I manually type in the IP address and URI for any page, it shows that I am logged in, so it works as expected. So, why does the redirect assume localhost? Both of my machines are linux-based. The laptop being Chrome OS. I am running nginx which proxies non-static file requests to jetty on port 8080.

• 504 Gateway Time-out after php fatal error

  - by tiagojsag

  I'm using nginx and php-fpm to develop a symfony2 based website, under ubuntu 12.10 (yes, I know I'm using a beta OS). Everything was working out fine until, due to an error on my code, I called an unexisting function, and got the following: Fatal error: Call to a member function (....) This isn't a problem (it's a bug in my code, easily fixable), but after this, no other page loads. My browser just keeps trying to load the page from the webserver, until nginx timeouts (after +- 30s, which should be some default timeout) and returns: 504 Gateway Time-out Restarting php-fpm solves the issue. Nginx logs show a timeout message, and nothing appears on php-fpm logs, even if I set them to debug level. I tried switching from fpm to fastcgi, and the same thing happens. I've looked around, but all similar error are related to big requests/file handling, which isn't the case. All the pages on my website load in a few seconds, even under development conditions (no caching, etc).

• VMWare and ALT GR key results in missing characters

  - by donat

  For some odd reason WMware products hijack the AltGy-key despite I make sure that other keys are used as hot keys to release mouse and keyboard from the virtual machine. While this is not a problem for US keyboards, european however who extensively use AltGR for characters such as pipe (|), at-sign (@), left brace ({) and right brace (}). This seem to happen both in Windows and Linux and I can not seem to find a solution that works for both. :( Anyone have an idea how to fix this without the need to modify the guest OS every time? Thank you.

• Barring connections if VPN is down.

  - by Majid

  I have a VPN account and use it for sensitive communication. However the VPN connection sometimes is dropped while my main connection to the internet is still alive. The pages I visit through VPN are on HTTP (not secure) and have javascript code which pings the host every minute or so on a timer. So it happens sometimes that the VPN connection is dropped and yet js sends a request to the server (with the cookies). How could I restrict connections so they only happen if the VPN is live? Edit - Some required details were missing OS: Windows XP SP2 Browser (mostly used): Google Chrome Firewall: Windows default Sites to filter: not all traffic but all in a list of sites like abc.com, xyz.com

• 14.04.1 LTS 64 bit from USB does not see my windows 7 when I go to install it

  - by W J

  I suppose this is as much a question as a heads up/warning 14.04.1 LTS only gave me the option of writing over everything on one of my windows 7 machines. If I'd pushed the wrong button and continued I would have lost some mighty important items. On a similar windows laptop I succesfully installed 14.04.1 LTS 32 bit alongside windows 7 rather easily ( and I dig it!), there was a prompt in that case that let me select to install it alongside my windows OS.Yikes, not in this case. This laptop was formatted NTFS, the Ubuntu usb pendrive I formatted fat32. could be a clue? It looks like there is an advanced install ubuntu, but I am not that advanced. I may try to use windows diskformat (What fdisk is gone?) to make a partition, then see if the ubuntu on my usb stick "sees" my windows. If anybody has a better plan let me know. Mahalo AHA!? p.s. its a SSD harddrive, perhaps thats the crux?

• Apple Airport Extreme Wireless Card M8881 Connectivity Issue

  - by Carlosfocker

  I bought a Apple Airport Extreme Wireless Card M8881 with the antenna for my old Power Mac G5 1.6 Ghz. The computer is running OS X 10.4. The card works and I can connect to my dlink 802.11g wireless router using WPA2/AES encryption. The problem is that the connection has intermittent connectivity issues. When the issue occurs the signal bars for the connection drop to one or two bars and the performance of the connection suffers greatly. The computer isn't far from the wireless router. I have a laptop at the desk where the mac is and it does not have any issues. I'm not sure what it might be? Updated drivers? Firmware? Let me know if I forgot any important information.

• LiveMeeting VC PowerShell PASS – Troubleshooting SQL Server with PowerShell

  - by Laerte Junior

  Guys, join me on Wednesday July 18th 12 noon EDT (GMT -4) for a presentation called Troubleshooting SQL Server With PowerShell. It will be in English, so please make allowances for this. I’m sure that you’re aware that my English is not perfect, but it is not so bad. I will do my best, you can be sure. The registration link will be available soon from PowerShell.sqlpass.org, so I hope to see you there. It will be a session without slides. Just code; pure PowerShell code. Trust me, We will see a lot of COOL stuff.Big thanks to Aaron Nelson (@sqlvariant) for the opportunity! Here are some more details about the presentation: “Troubleshooting SQL Server with PowerShell – The Next Level’ It is normal for us to have to face poorly performing queries or even complete failure in our SQL server environments. This can happen for a variety of reasons including poor Database Designs, hardware failure, improperly-configured systems and OS Updates applied without testing. As Database Administrators, we need to take precaution to minimize the impact of these problems when they occur, and so we need the tools and methodology required to identify and solve issues quickly. In this Session we will use PowerShell to explore some common troubleshooting techniques used in our day-to-day work as s DBA. This will include a variety of such activities including Gathering Performance Counters in several servers at the same time using background jobs, identifying Blocked Sessions and Reading & filtering the SQL Error Log even if the Instance is offline The approach will be using some advanced PowerShell techniques that allow us to scale the code for multiple servers and run the data collection in asynchronous mode.

• Why is my fresh install of 12.04 running slow?

  - by user75129

  Hey guys I'm a new linux user, I figured it would be the best for the laptop I just purchased because it's said to be faster than Windows 7. I'm currently dual-booting with Windows 7 Professial and Ubuntu 12.04. The laptop I am using is the LG X Note P210 Specs: Intel Core i5 470UM Dual Core clocked at 1.33GHz 12.5" HD LED LCD Screen at 1366 by 768 4GB DDR3 @ 1333 MHz RAM Integrated Intel HD Graphics Card 4 Cell Battery with 3150mAh It comes loaded Windows 7 Home Premium 64-Bit, it runs fine on that but my Ubuntu 12.04 runs slower than it and I don't understand why, it definitely has decent specs to run even a 64-bit operating system and do some gaming. Granted I know it's not the best but for a laptop it does the job so Ubuntu should work especially since it's said to make older units with worse specs run even better. I'm not all that familiar with coding and all so what are things I can do to optimize speed without overclocking? Boot up is fine, its program response time I believe, once Im in the actual OS, it lags, slows down, apps stop working, take forever to load up apps.

• FoxPro 2.6 DOS on Windows 7 64-bit

  - by Rolando

  I support a company that has a very old, mission critical, FoxPro for DOS 2.6 (FPD) application. For variuos reasons the company didn't adapt/migrate their app, which, ironically, has been running even better under Windows XP (and 32-bit Win7) because the OS allowed new features like more reliable networking, distributed printing, email integration. Unfortunately for this company, most new machines now come with a 64-bit version of Windows 7, which is incompatible with their FPD app. I know this time the writing is on the wall: the only long-term solution is to migrate their app. But I wonder if anyone can suggest a temporary alternative path, which doesn't involve either: downgrade 64-bit Windows to 32-bit, or run the app on a virtualized 32-bit XP

• Is there an alternative to SDL 1.3 for a C++ game that should run on iOS and Android?

  - by futlib

  I've used SDL for many desktop games, always as the cross-platform glue for: Creating a window Processing input Rendering images Rendering fonts Playing sounds/music It has never disappointed me at those tasks. But when it comes to graphics, I prefer to work with the OpenGL API directly, even though all of our games are 2D. In the project I'm currently working on, I've made sure to only use the API subset supported by both OpenGL 1.3 and OpenGL 1.0, so making the thing run on Android should be easy, I thought. Turns out there is no official Android or iOS port of SDL yet. However, there's one in SDL 1.3, which is still in development. SDL 1.3 doesn't seem very appealing to me for three reasons: It's been in development for at least 4 years, and I have no idea when it will be done, not to mention stable. It's not ported to as many platforms as SDL 1.2. From what I've seen, it uses OpenGL for drawing, so I suppose the community will move away from directly using OpenGL. So I'm wondering if I should use a different library for our current project - it doesn't matter much if I need to port my existing code from SDL 1.2 to SDL 1.3 or to some other library. We're planning to release on Windows, Mac OS X, Linux, iOS and Android, so good support for these platforms is essential. Is there anything stable that does what I want?
