• Why shouldn't I always use nullable types in C#.

  - by Matthew Vines

  I've been searching for some good guidance on this since the concept was introduced in .net 2.0. Why would I ever want to use non-nullable data types in c#? (A better question is why wouldn't I choose nullable types by default, and only use non-nullable types when that explicitly makes sense.) Is there a 'significant' performance hit to choosing a nullable data type over its non-nullable peer? I much prefer to check my values against null instead of Guid.empty, string.empty, DateTime.MinValue,<= 0, etc, and to work with nullable types in general. And the only reason I don't choose nullable types more often is the itchy feeling in the back of my head that makes me feel like it's more than backwards compatibility that forces that extra '?' character to explicitly allow a null value. Is there anybody out there that always (most always) chooses nullable types rather than non-nullable types? Thanks for your time,

• Copy iMovie 11 project from one account to another user account?

  - by David.Chu.ca

  I have one user account as admin with several iMovie projects. After a period of time, I created a standard user account. Now I want to move admin user's iMovie projects to standard user. What I tried was to copy admin's Movies folder content to standard user by dropping to standard user's public shared dropbox. Then I copied the content to standard user's Movies folder. However, I cannot see iMovie projects in standard user by iMovie app. Is there anyway to move projects from one user to another user? Or copy one user's data to another user? Not sure if I missed anything if just copying Movies folder?

• Dubious permissions on plist Problems installing Jenkins

  - by Code Droid

  I am trying to install jenkins on 10.6.8 In order to do this I needed to modify the jenkins plist which was owned by root. I gave myself (the admin) permissions to modify this file and added the admin as the user in the plist for jenkins. Now the problem is that launchctrl sees my permission change as a security issue and will not launch something about dubious permissions on plist. I changed owner to root, and removed admin permission to write but launchctrl still views the permissions as dubious? Time for a reinstall? How should I have set the plist in the first place? and what should I do now?

• upgraded to OSX 10.6.6 - now cannot sudo

  - by rahulk

  I've been using sudo until now. After an upgrade to 10.6.6, now sudo gives me incorrect password. My user has admin rights, and i can execute admin functions from the GUI (such as System Prefs, updating software etc). However, within Terminal, sudo has stopped accepting the password. I have repaired permissions and restarted. Some pointers ask me to use Directory Utility, but in this version it does not have a "set root user" option. I downloaded ServerAdminTool 10.5.7 but this does not work on my system. Some say to add myself to "wheel" group, but i need sudo for that. Some say if i am in admin group, i should be able to sudo, but this is not happening. (Using OS X Snow Leopard 10.6.6, earlier 10.5.8) MODERATOR: please delete this question. The issue had to do with Textpander expanding the password resulting in sudo failing. Not an OS upgrade issue.

• Regedit as Current User

  - by user1013264

  I'm trying to apply a registry fix for an Outlook/O365 issue on a user's account. The issue is that "regedit" is blocked by a domain GPO. I'm able to run "gpedit" using the local admin account. Question : When I run "regedit as the local admin, am I modifying the registry for the local admin user or the domain user who's actually logged onto the workstation? I'm trying to apply the following fix: http://support.microsoft.com/kb/2843677 Also, the path for the above mentioned registry should end in " \Preferences" which is what I'm unable to locate. I'm able to navigate up until \Outlook. Any suggestions would be appreciated. Thank you. Running Outlook 2010.

• Adobe Coldfusion Railo OpenBD Apache Tomcat Multiple Sites

  - by chris hough

  Here's what I am trying to do, unless I am crazy: I am trying to use Tomcat with the multiple workers, so far I got OpenBD working, but having trouble with Railo, and will be tackling Adobe after. each engine deployed as a war separated by different workers I wanted to keep both the sites and engines inside my sites directory I have to remap the symlink for the WEB-INF when I switch engines = have not found a way around this my thought is to have everything separated into modules and I want to be able to execute both cfm and php code in a single site.  Ideally, it would be amazing if there would be a way to not have to remap the symlink as well. thoughts? can this be done?

• Which Linux book for aspiring sysadmin?

  - by Ramy

  I have a co-worker who insists that he will never buy a book unless it is considered "THE" book. So, in this vein, I thought I'd ask what the ultimate Linux book is. I wouldn't quite call myself a complete beginner since I can get around in Linux in general pretty well. But, beyond that, I'm also looking for a book with an eye towards becoming a Sys Admin someday. I saw a Junior Sys Admin position open up recently but with the requisite 2-3 years experience, I may have to wait a little while longer before I'm ready to apply for such a position. Having said all that, I'll summarize my question: What is the ultimate Linux book for someone who is ok with the basic tasks of getting around in Linux but also wants to aim towards full Sys Admin status someday? A few examples of the books I'm considering: Linux-Administration-Beginners-Guide-Fifth Linux-System-Administration Linux-System-Administration EDIT: Before you close this question as a dup, I'd like to say that I'm looking for something that goes deeper than this: Book for linux newbies I already have "Linux in a nutshell"

I have some programs needs admin rights for example I have French dictionary without admin right the program will not work properly. I don't want go to each PC and login with admin account then go to program folder located in programs files to give full permission to the group.

• Java: volatile guarantees and out-of-order execution

  - by WizardOfOdds

  Note that this question is solely about the volatile keyword and the volatile guarantees: it is not about the synchronized keyword (so please don't answer "you must use synchronize" for I don't have any issue to solve: I simply want to understand the volatile guarantees (or lack of guarantees) regarding out-of-order execution). Say we have an object containing two volatile String references that are initialized to null by the constructor and that we have only one way to modify the two String: by calling setBoth(...) and that we can only set their references afterwards to non-null reference (only the constructor is allowed to set them to null). For example (it's just an example, there's no question yet): public class SO { private volatile String a; private volatile String b; public SO() { a = null; b = null; } public void setBoth( @NotNull final String one, @NotNull final String two ) { a = one; b = two; } public String getA() { return a; } public String getB() { return b; } } In setBoth(...), the line assigning the non-null parameter "a" appears before the line assigning the non-null parameter "b". Then if I do this (once again, there's no question, the question is coming next): if ( so.getB() != null ) { System.out.println( so.getA().length ); } Am I correct in my understanding that due to out-of-order execution I can get a NullPointerException? In other words: there's no guarantee that because I read a non-null "b" I'll read a non-null "a"? Because due to out-of-order (multi)processor and the way volatile works "b" could be assigned before "a"? volatile guarantees that reads subsequent to a write shall always see the last written value, but here there's an out-of-order "issue" right? (once again, the "issue" is made on purpose to try to understand the semantics of the volatile keyword and the Java Memory Model, not to solve a problem).

• My linux server takes more than an hour to boot. Suggestions?

  I am building a CentOS 5.4 system that boots off a compact flash card using a card reader that emulates an IDE drive. It literally takes about an hour to boot. The ultra-slow part occurs when Grub is loading the kernel. Once that's done, the rest of the boot process only takes about a minute to get to a login prompt. Does anyone have any suggestions? I suspect that it may have to do with UDMA. Everything IDE-related in my BIOS seems to checkout. The read performance hdparm is telling me 1.77 MB/s. Ouch! (But even at that rate, it still shouldn't take an hour to decompress and load the kernel) [root@server ~]# hdparm -tT /dev/hdc /dev/hdc: Timing cached reads: 2444 MB in 2.00 seconds = 1222.04 MB/sec Timing buffered disk reads: 6 MB in 3.39 seconds = 1.77 MB/sec Trying to enable DMA is a no-go though: [root@server ~]# hdparm -d1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) Here's some command outputs that might help: System [root@server ~]# uname -a Linux server.localdomain 2.6.18-164.el5xen #1 SMP Thu Sep 3 04:47:32 EDT 2009 i686 i686 i386 GNU/Linux PCI info: [root@server ~]# lspci -v 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) Subsystem: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation 82945G/GZ Integrated Graphics Controller Flags: bus master, fast devsel, latency 0, IRQ 10 Memory at fdf00000 (32-bit, non-prefetchable) [size=512K] I/O ports at ff00 [size=8] Memory at d0000000 (32-bit, prefetchable) [size=256M] Memory at fdf80000 (32-bit, non-prefetchable) [size=256K] Capabilities: [90] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- Capabilities: [d0] Power Management version 2 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 Flags: bus master, medium devsel, latency 0, IRQ 16 I/O ports at fe00 [size=32] 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 Flags: bus master, medium devsel, latency 0, IRQ 17 I/O ports at fd00 [size=32] 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 Flags: bus master, medium devsel, latency 0, IRQ 18 I/O ports at fc00 [size=32] 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) (prog-if 00 [UHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 Flags: bus master, medium devsel, latency 0, IRQ 19 I/O ports at fb00 [size=32] 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) (prog-if 20 [EHCI]) Subsystem: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller Flags: bus master, medium devsel, latency 0, IRQ 16 Memory at fdfff000 (32-bit, non-prefetchable) [size=1K] Capabilities: [50] Power Management version 2 Capabilities: [58] Debug port 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) (prog-if 01 [Subtractive decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=01, subordinate=01, sec-latency=32 I/O behind bridge: 0000d000-0000dfff Memory behind bridge: fde00000-fdefffff Prefetchable memory behind bridge: 00000000fdd00000-00000000fdd00000 Capabilities: [50] #0d [0000] 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) Subsystem: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge Flags: bus master, medium devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) (prog-if 80 [Master]) Subsystem: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 17 I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at f800 [size=16] Capabilities: [70] Power Management version 2 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) Subsystem: Intel Corporation 82801G (ICH7 Family) SMBus Controller Flags: medium devsel, IRQ 17 I/O ports at 0500 [size=32] 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Apache file negotiation failed

  - by lorenzo.marcon

  I'm having the following issue on a host using Apache 2.2.22 + PHP 5.4.0 I need to provide the file /home/server1/htdocs/admin/contents.php when a user makes the request: http://server1/admin/contents, but I obtain this message on the server error_log. Negotiation: discovered file(s) matching request: /home/server1/htdocs/admin/contents (None could be negotiated) Notice that I have mod_negotiation enabled and MultiViews among the options for the related virtualhost: <Directory "/home/server1/htdocs"> Options Indexes Includes FollowSymLinks MultiViews Order allow,deny Allow from all AllowOverride All </Directory> I also use mod_rewrite, with the following .htaccess rules: RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([^\./]*)$ index.php?t=$1 [L] </IfModule> It seems very strange, but on the same box with PHP 5.3.6 it used to work correctly. I'm just trying an upgrade to PHP 5.4.0, but I cannot solve this negotiation issue. Any idea on why Apache cannot match contents.php when asking for content (which should be what mod_negotiation is supposed to do)?

• how to effectively modify index

  - by daedlus

  Hej everyone, problem : I am looking for right way to convert an index from clustered to non-clustered Description : I have a table as below in sybase db: dbo.UserLog Id | UserId |time | .... This is hash partitioned using UserId. Currently it has 2 indexes UserId : non-clustered time: clustered This table has about 20 million records. I now want to make UserId as clustered index and time as non-clustered index. is it correct to user alter index to change from clustered to non-clustered or do i drop index and recreate. does the fact that userId is used in hash partitioning have any implications to this? To me alter seems way to go but I have not yet tried this.

• Nginx RegEx to match a directory and file

• Not able to recieve mails in my mailbox

  - by jestges

  Hi, I've configured google apps (google services) to my domain for access mails some thing like mail.mysite.com. I've configured successfully all the accounts include admin and users also. But here the surprising thing is I cant able to receive any mails when i sent mails to [email protected]. But I can able to send mails from the same account ([email protected])to any other email ids. Anybody know the reason? I'm working on the same thing from the week. Thanks in advance

• How to allow program updates without prompting UAC?

  - by Ryan Mortier

  We have about 15-20 users who have this software installed. We have UAC enabled through GPO as you should, which means the software prompts for admin approval if a standard user trys to install it. Thats fine, they can call the help desk to have the software installed. My problem is, our help desk is being bombarded every day because users can't update the software and there are updates almost every day which is prompting UAC. Using procmon.exe to find out where it was trying to write to, I then created a GPO to allow file permission access to the program files folder for this particular software, including the program data folder, but it still prompts for admin approval. It seems as though that the software is using msiexec.exe to run a .msp patch file. The only "ACCESS DENIED"s I can still see in procmon is things like this: What can I possibly do to stop this software from prompting UAC with admin password credentials aside from disabling UAC?

• How to minimize total cost of shortest path tree

  - by Michael

  I have a directed acyclic graph with positive edge-weights. It has a single source and a set of targets (vertices furthest from the source). I find the shortest paths from the source to each target. Some of these paths overlap. What I want is a shortest path tree which minimizes the total sum of weights over all edges. For example, consider two of the targets. Given all edge weights equal, if they share a single shortest path for most of their length, then that is preferable to two mostly non-overlapping shortest paths (fewer edges in the tree equals lower overall cost). Another example: two paths are non-overlapping for a small part of their length, with high cost for the non-overlapping paths, but low cost for the long shared path (low combined cost). On the other hand, two paths are non-overlapping for most of their length, with low costs for the non-overlapping paths, but high cost for the short shared path (also, low combined cost). There are many combinations. I want to find solutions with the lowest overall cost, given all the shortest paths from source to target. Does this ring any bells with anyone? Can anyone point me to relevant algorithms or analogous applications? Cheers!

• Openfire: Closing session due to incorrect hostname

  - by cvista

  I have a fresh install on a windows sevrer 2008 box. I can connect adium to the server from a remote machine and from the admin console/sessions I can see my session. My friend can aslo connect and I can see his session. I can send an admin message out and both of us can see it in the adium clients. We can't see each other though. I also get these logs in the warn window in the log viewer: Closing session due to incorrect hostname in stream header. Host: prjatk.com. Connection: org.jivesoftware.openfire.net.SocketConnection@1b1fd9c socket: Socket[addr=/109.109.248.82,port=56258,localport=5269] session: null prjatk.com is the server - however in the server settings on the admin screen I see the computer name as the hostname - is that the issue? If so how can I change that?

• Overloading assignment operator in C++

  - by jasonline

  As I've understand, when overloading operator=, the return value should should be a non-const reference. A& A::operator=( const A& ) { // check for self-assignment, do assignment return *this; } It is non-const to allow non-const member functions to be called in cases like: ( a = b ).f(); But why should it return a reference? In what instance will it give a problem if the return value is not declared a reference, let's say return by value?

• Virtualhost Wildcard Subdomains

  We have one static IP on which we have routed our company website. We have setup a local machine on windows with WAMP to run our testing server. We want virtual hosts to test our different apps. However, when creating subdomains, we have a new project which uses wildcard subdomains. How can we create the wildcard subdomains in VirtualHosts. We use, NameVirtualHost * <VirtualHost *> ServerAdmin admin@test DocumentRoot "E:/Wamp/www/corporate" ServerName companysite.com </VirtualHost> <VirtualHost *> ServerAdmin admin@test DocumentRoot "E:/Wamp/www/project" ServerName project.companysite.com </VirtualHost> <VirtualHost *> ServerAdmin admin@test DocumentRoot "E:/Wamp/www/project" ServerName *.project.companysite.com </VirtualHost> However, the last * wildcard does not work. Any help?
