• How to use an USB digitizer?

  - by Magnetic_dud

  Hello, i am in China now, and when i saw an USB digitizer (resistive), i bought it, thinking that i could be used as a mouse. When i connect it to my windows 7 rc1 laptop, the system properties says "pen input available" But, nothing happens when i touch the panel... i installed the bundled drivers, in chinese only, and NOT in unicode (so the text is garbled) When i install the driver, i get access to a special key on the tablet, "switch from pen input to mouse", and the driver will move the pointer according to the position on the tablet. (but no click) If i use the "pen mode", the computer will use a special chinese IME that is very awkard, i want to use the microsoft ime, and be able to draw/take notes on the screen There are "generic" drivers? Or just a plain mouse driver that will click when i press on the surface The tablet name is "qiancai"

• When my UIViewController accesses an NSArray in my AppDelegate from an IBAction it crashes the progr

  - by JasonClark

  I have a couple UIViewControllers that I am trying to access an array inside my AppDelegate. When I use an IBAction UIButton and in that method I access my AppDelegate my program dies silently. Nothing in output or the debugger, it just stops. If I run it several times I can see that it is failing to access the array properly. To investigate this problem I created a very basic app. In my AppDelegate.h I declared and set properties for the array #import <UIKit/UIKit.h> @class MyViewController; @interface MyAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; MyViewController *viewController; NSArray *images; } @property (nonatomic, retain) NSArray *images; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet MyViewController *viewController;` In the AppDelegate.m I synthesised and initialized the NSArray (Also made sure the images were added to the Resources folder). @synthesize images; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { images = [NSArray arrayWithObjects: [[NSBundle mainBundle] pathForResource:@"bamboo_nw" ofType:@"jpg"], ..... nil]; NSLog(@"init images size:%i",[images count]); [window addSubview:viewController.view]; [window makeKeyAndVisible]; return YES; } In my UIViewController.h I added class, imported header file, declared, and set properties for my AppDelegate pointer. #import <UIKit/UIKit.h> #import "MyAppDelegate.h" @class MyAppDelegate; @interface MyViewController : UIViewController { MyAppDelegate *mainDelegate; IBOutlet UIButton mybutton; } @property (nonatomic, retain) MyAppDelegate mainDelegate; @property (nonatomic, retain) UIButton *mybutton; -(IBAction) doSomething;` In my UIViewController.m I synthesize and assign my AppDelegate. I set up an IBAction that will log the same count of the NSArray from the AppDelegate. #import "MyViewController.h" #import "MyAppDelegate.h" @implementation MyViewController @synthesize mybutton; - (void)viewDidLoad { mainDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; NSLog(@"vdl images size:%i",[mainDelegate.images count]); [super viewDidLoad]; } -(IBAction) doSomething { NSLog(@"ds images size:%i",[mainDelegate.images count]); } I print the size of the NSArray in the AppDelegate when I create it, in the ViewController when I first assign my AppDelegate pointer, and then as a result of my IBAction. I find that everytime I hit the button the program dies. On the third time I hit the button, I saw that it ran my IBAction but printed my array size as 1 instead of 8. Am I missing something? Also, why don't I get stack traces or anything, the debugger just dies silently? Thanks in advance for any help! Debugger Console output for 3 runs: [Session started at 2010-05-10 06:21:32 -0700.] 2010-05-10 06:21:44.865 My[59695:207] init images size:8 2010-05-10 06:21:47.246 My[59695:207] vdl images size:8 [Session started at 2010-05-10 06:22:15 -0700.] 2010-05-10 06:22:18.920 My[59704:207] init images size:8 2010-05-10 06:22:19.043 My[59704:207] vdl images size:8 [Session started at 2010-05-10 06:22:23 -0700.] 2010-05-10 06:22:25.966 My[59707:207] init images size:8 2010-05-10 06:22:26.017 My[59707:207] vdl images size:8 2010-05-10 06:22:27.814 My[59707:207] ds images size:1

• ZFS: RAIDZ versus stripe with ditto blocks

  - by RandomInsano

  I'm going to build a ZFS file server from FreeBSD. I learned recently that I can't expand a RAIDZ udev once it's part of the pool. That's a problem since I'm a home user and will probably add one disk a year tops. But what if I set copies=3 against my entire pool and just throw individual drives into the pool separated? I've read somewheres that the copies will try and distribute across drives if possible. Is there a guarantee there? I really just want protection from bit rot and drive failure on the cheap. Speed's not an issue since it'll go over a 1Gb network and at MOST stream 720p podcasts. Would my data be guaranteed safe from a single drive failure? Are there things I'm not considering? Any and all input is appreciated.

• avoid dupllcate copies in thunderbird when using gmail labels

  - by mandy

  I like the system of multiple gmail labels but am concerned about space used. I think that TB stores a separate copy of the whole email in every folder corresponding to a gmail label [including a copy in the "allmail" folder along with a separate copy in the each of the other folders]. Can I arrange to store a single copy of the email in TB,[perhaps in the allmail folder] with a shortcut type pointer from the individual folders to that single copy.[i.e for every email with one gmail label [eg personal] there are already 2 copies in TB, one in the allmail folder and a second in the "personal" folder

• LAN speeds and firewall/switch connections

  - by microchasm

  I have a small network with about ten users. All workstations flow into a Dell PowerConnect 3424 which then has a single link to a SonicWALL firewall and from there to a cable modem. More important than internet connectivity is speed between machines (specifically a Windows Server box on the LAN which everyone uses simultaneously). I believe the 3424 has gigabit connections, but they look like they're for stacking. Is there a way to test the speeds on the LAN to see where the speeds are at? Is there any low-hanging fruit insofar as increasing speeds?

• Computer freezes for 2+ seconds, mouse still moves

  - by xsaero00

  I have this problem on my workstation. The computer would effectively freeze for 2-5 seconds for no apparent reason, then continue as normal. While frozen the mouse would still be movable, but only on one of screens in my multi-screen setup. What can be the likely cause. System: CPU: i7-920 Memory: 12G of Patriot DDR3, 6 modules OS: SLED 11, Suse Linux Enterprise Desktop, using Gnome Main board: Asus P6T Video: two Nvidia 9500GT connected to three displays I am using memory at recommended settings of 8-8-8-1333. It has an XMP profile. Th CPU is a bit overclocked to 3.3 GHz, but my cooling more than allows for it. I ran the computer with all overclocks off and lower memory speed but the issue was still there. Any ideas? Where should I start looking?

• Kaspersky AV is slowing down my connection significantly

  - by KeyStroke

  Hi, I'm using Kaspersky AV 2010, and I've noticed recently in Firefox (DownThemAll download manager) that my download speed has been significantly reduced after installing Kaspersky (from 450 kb/s to 30 kb/s!!). I can solve the issue temporarily by pausing protection and then resuming it again. But it's getting frustrating since I have to do this every few hours. Also another issue I have with the AV (which could be related) is that it forces all network traffic to go through it! (Nod32 didnt do that). Any idea what could be causing this? Your help is much appreciated

• Create and use intermediate certificate authority on Windows Server 2012?

  - by Sid

  Background: Server OS is Windows Server 2012. GUI is installed as we come upto speed with powershell. Setup is staging, not production (yet). We have our (internal, domain limited) Root CA installed. I would like to take the Root CA offline to secure storage but before that I'd like to setup an intermediate CA which can take over actual live, online (int-RA-net) functionality Can someone guide me covering: creating the intermediate CA certificate request installing the intermediate CA certificate on domain controller (certification authority role already installed with Root CA online right now) use the intermediate CA to generate a certificate (any use certificate, just for demonstration purposes) Obviously this certification chain would be invalid on computers outside our domain (self trusted root - our root certificate is NOT from common 3rd parties). This last point is NOT a problem.

• FreeNas running on ESXi - sometimes gets very slugish.

  - by Luma

  Hello everyone, I have a ESXi server (dual quad core, 8GB of DDR3 ram, 6x 1TB WD Blacks running in RAid 5 on the PErc 6/i controller. I have a 64bit freenas VM running, on this VM I keep about 200Gigs of stuff that my windows machines access. every now and then the throughput of this VM just dies, for example right now it can't even handle streaming a song and when I tried to transfer a folder the speed goes from 10-400KB/s. Might I add at this point that the ESXi box has dual gigabit network cards plugged into a good solid gigabit switch and other linux and windows VM's are just fine I have seen speeds over 90MB/s (frequently) The server still has ram left over (plenty actually) and cpu is very low (500-1000mhz) any ideas what could cause this? thanks.

All systems run linux and have root acces to all. Need securely rsync internal_server_1:/some/path into internal_server_2:/another/path My idea is make ssh secure tunnel between two firewalls, e.g. from firewall_1 firewall1# ssh -N -p 22 -c 3des user2@firewall_2.example.com -L xxx/10.3.0.3/xxxx and after will run rsync from internal_server_1 somewhat like: intenal1# rsync -az /some/path [email protected]:/another/path I don't know how to make a correct ssh tunnel for rsync (what ports need tunnel) and to where i will make the rsync? (remote comp address in case of ssh tunnel) Any idea or pointer to helpfull internet resource for this case? thanx.

• Varnish: User specific pages

  - by jchong0707

  I'm new to Varnish and am interested in using it to speed up my web application I wanted to know if Varnish can handle caching and serving user specific content. For example if I have a page say for example /welcome which is dynamically generated in the backend and is user specific So if User John Smith shows up to /welcome it'll show in the page itself 'Welcome John Smith' and if Bob Smith shows up to /welcome it'll show 'Welcome Bob Smith' Ideally both of those /welcome pages will be cached for each unique User, is this something Varnish can do? (is this even a good Use Case of Varnish?) Thanks!

• Boost::Spirit::Qi autorules -- avoiding repeated copying of AST data structures

  - by phooji

  I've been using Qi and Karma to do some processing on several small languages. Most of the grammars are pretty small (20-40 rules). I've been able to use autorules almost exclusively, so my parse trees consist entirely of variants, structs, and std::vectors. This setup works great for the common case: 1) parse something (Qi), 2) make minor manipulations to the parse tree (visitor), and 3) output something (Karma). However, I'm concerned about what will happen if I want to make complex structural changes to a syntax tree, like moving big subtrees around. Consider the following toy example: A grammar for s-expr-style logical expressions that uses autorules... // Inside grammar class; rule names match struct names... pexpr %= pand | por | var | bconst; pand %= lit("(and ") >> (pexpr % lit(" ")) >> ")"; por %= lit("(or ") >> (pexpr % lit(" ")) >> ")"; pnot %= lit("(not ") >> pexpr >> ")"; ... which leads to parse tree representation that looks like this... struct var { std::string name; }; struct bconst { bool val; }; struct pand; struct por; struct pnot; typedef boost::variant<bconst, var, boost::recursive_wrapper<pand>, boost::recursive_wrapper<por>, boost::recursive_wrapper<pnot> > pexpr; struct pand { std::vector<pexpr> operands; }; struct por { std::vector<pexpr> operands; }; struct pnot { pexpr victim; }; // Many Fusion Macros here Suppose I have a parse tree that looks something like this: pand / ... \ por por / \ / \ var var var var (The ellipsis means 'many more children of similar shape for pand.') Now, suppose that I want negate each of the por nodes, so that the end result is: pand / ... \ pnot pnot | | por por / \ / \ var var var var The direct approach would be, for each por subtree: - create pnot node (copies por in construction); - re-assign the appropriate vector slot in the pand node (copies pnot node and its por subtree). Alternatively, I could construct a separate vector, and then replace (swap) the pand vector wholesale, eliminating a second round of copying. All of this seems cumbersome compared to a pointer-based tree representation, which would allow for the pnot nodes to be inserted without any copying of existing nodes. My question: Is there a way to avoid copy-heavy tree manipulations with autorule-compliant data structures? Should I bite the bullet and just use non-autorules to build a pointer-based AST (e.g., http://boost-spirit.com/home/2010/03/11/s-expressions-and-variants/)?

• Why do I have to manually 'Restart Management Network' on vSphere 5 host after reboot to get networking available?

  - by growse

  I've got a couple of vSphere 5.0 hosts in a small lab environment here and I've noticed a strange behaviour. When on of the hosts gets rebooted, it is unresponsive to the network until I log into the ESX console, Press F2 to customize and select Restart management network. Once this is done, the networking works perfectly as expected. Each host has two NICs which are trunked together using Etherchannel to a Cisco 3750. The link is also a .1q VLAN trunk and the management network is configured on VLAN121 with the VM traffic configured on VLAN118. Why would the host be completely dead to the world until I physically kick it?

• Firefox and Flash requires 2 clicks after Scrolling?

  - by Kerry

  I've noticed this with me and my partners computers, take a look at this: http://www.uploadify.com/demo/ Those buttons are flash. If you scroll (scroll to the bottom then back up, using your mouse scroll) then hover over a button, it is a normal pointer, not a hand. If you click on the button, then it turns into a hand, then you can click on it to trigger the browse files window. Is there any way to fix this? Is this a Firefox bug (doesn't happen in Chrome or IE8)?

• Mouse Icon Distorted on Secondary Display

  - by Nathan Taylor

  I have a strange issue with a dual monitor, extended desktop setup where the mouse is always fine on the primary monitor, but sometimes when I move to the secondary display the icon becomes garbled and distorted (sometimes it just looks like a vertical line, instead of a pointer). If I move the mouse back and forth rapidly between primary and secondary displays the level of "garbledness" of the icon will change and sometimes go away completely. If I switch the display settings and set it to "Duplicate Monitor 1" then I end up with a garbled icon on the primary display and an accurate one on the secondary. Very annoying. Computer is Windows 7 Ultimate with an HD8750 and the newest video drivers. Monitors are two Dell 24" displays connected via DVI cables. I have also tried VGA cables.

• Ubuntu: Take actions when system temperature gets too high

  - by Josh

  One of the CPU fans on my Compaq Presario laptop running Ubuntu 9.10 seems to have bit the dust. The fan is deep within the case and I intend to replace the laptop in the next 6 months so it's not worth replacing it. I have the laptop on a cooling pad and most of the time the system is fine, CPU temps around 90°-110°F. Occasionally, however, I'm seeing random lockups which I believe is due to the system overheating. How can I configure the system to: Lower the CPU speed when the temperature reaches a certain level? (I.E. 110°F) Shutdown the system when the tempature reaches a critical level? (And what would that be? 130°?)

• First requests are painfully slow

  - by winSharp93

  I am running Redmine under IIS using Zoo. Installation was done using the Web Platform Installer and the default configuration has not been touched. However, when using the application, the first requests take very long to complete (sometimes more than one minute). During that time, the ruby.exe causes some CPU load (about 15%). According to the log files, it's mainly the views taking that long to render: Started GET "/redmine/login" for IP at 2012-09-04 09:54:08 +0200 Processing by AccountController#login as HTML Rendered account/login.html.erb within layouts/base (42150.5ms) Completed 200 OK in 43508ms (Views: 43008.5ms | ActiveRecord: 0.0ms) Rendered account/login.html.erb within layouts/base (42435.1ms) Completed 200 OK in 44100ms (Views: 43523.3ms | ActiveRecord: 0.0ms) After the initial delay, further request times are totally acceptable. Any ideas on how to speed up the warmup time?

• Random users randomly being unable to connect to my static content domain

  - by jls33fsls

  I store all of my images, js, and css files on a separate domain to try and speed up page load times (it isn't a CDN, just a separate domain on the same server). This works fine for 99% of the users, 99% of the time. However, there are users that randomly are unable to connect to the static content domain for periods of 1-5 hours. They can go to the main site, but no images will load and everything is just white because no css is being loaded. If they go to the static content domain itself, the page just idles for a while and then times out with a blank white page, no error messages. I have no idea what could be causing this, and it hasn't happened to me, any ideas? I am running Apache on CentOS 5.5.

• Home Server restore fails cannot find boot device

  - by Tim Heuer

  I am using Windows Home Server to backup my PCs. I recently had a hard drive failure on one of my WHS connected PCs and obtained an identical sized/speed drive for my laptop. I used the latest home server restore CD and did the restore. It said it completed successfully. Upon reboot, it says 'cannot find boot device' and lists all my drives (hard drive, cd, network book) indicating no valid operating system was found. I boot using the Win7 repair disk and while it doesn't see the operating system, it sees the drive and if I go into a command prompt, I can see all my data on the drive. My laptop is Windows 7 64-bit Ultimate. I've tried most everything I can think of. I'm a technical user (software developer) so I'm pretty aware of how things work (or should). I don't feel like I'm missing a simple step here.

• Is a larger hard drive with the same cache, rpm, and bus type faster?

  - by Joel Coehoorn

  I recently heard that, all else being equal, larger hard are faster than smaller. It has to do with more bits passing under the read head as the drive spins - since a large drive packs the bits more tightly, the same amount of spin/time presents more data to the read head. I had not heard this before, and was inclined to believe the the read heads expected bits at a specific rate and would instead stagger data, so that the two drives would be the same speed. I now find myself looking at purchasing one of two computer models for the school where I work. One model has an 80GB drive, the other a 400GB (for ~$13 more). The size of the drive is immaterial, since users will keep their files on a file server where they can be backed up. But if the 400GB drive will really deliver a performance boost to the hard drive, the extra money is probably worth it. Thoughts?

• Changes to talk/ytalk or alternative chat in the Linux terminal

  - by cascaval

  While looking for a piece of software that provides chat between 2 Linux server users logged in the terminal, I tried talk/ytalk. Unfortuntaley it provides chat between users on separate walls (each user has its own wall) and the messages lack timestamps. Is it possible to set it up so that at least timestamps are provided? Alternatively, is there any other software that could provide one wall on which users write messages prepended with time? Simple chat with messages listed in the order of submission would be ideal: 13:05:48 [bridgekeeper@...]: What is the air-speed velocity of an unladen swallow? 13:06:28 [cascaval@...]: What do you mean? An African or European swallow? I already tried wall and write but they don't fit the bill. OS: Debian 6.0

• What are the specifications on the RAM inside my computer?

  - by Faken

  I have a Dell Dimension 9200 that I bought 4 years ago. I want to find out the exact specifications (manufacturer, speed, timings, etc.). Is there a way to get this specific info without having to open up the PC (it's buried in and under a bunch of furniture, I'd perfer not to have to dig it out). All I know about it right now is that it is 4 1GB sticks of DDR2 RAM at 667 Mhz. It is the standard RAM that shipped with the computer 4 years ago (from Dell). Does anyone know what the specifications are of the RAM that Dell used in this particular model of computer 4 years ago? Note: I've done my research before coming here. CPU-Z, EVEREST, and AIDA32 all have been unable to give me any more information other than 4 x 1GB @ 667Mhz. I can't find any specifications in the Dell online manuals either (at least not as specific as I want). Thanks -Faken
