• Why is the latency on one LVM volume consistently higher?

  - by David Schmitt

  I've got a server with LVM over RAID1. One of the volumes has a consistently higher IO latency (as measured by the diskstats_latency munin plugin) than the other volumes from the same group. As you can see, the dark orange /root volume has consistently high IO latency. Actually ten times the average latency of the physical devices. It also has the highest Min and Max values. My main concern are not the peaks, which occur under high load, but the constant load on (semi-)idle. The server is running Debian Squeeze with the VServer kernel and has four VServer containers and one KVM guest. I'm looking for ways to fix - or at least understand - this situation. Here're some parts of the system configuration: root@kvmhost2:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/system--host-root 19G 3.8G 14G 22% / tmpfs 16G 0 16G 0% /lib/init/rw udev 16G 224K 16G 1% /dev tmpfs 16G 0 16G 0% /dev/shm /dev/md0 942M 37M 858M 5% /boot /dev/mapper/system--host-isos 28G 19G 8.1G 70% /srv/isos /dev/mapper/system--host-vs_a 30G 23G 6.0G 79% /var/lib/vservers/a /dev/mapper/system--host-vs_b 5.0G 594M 4.1G 13% /var/lib/vservers/b /dev/mapper/system--host-vs_c 5.0G 555M 4.2G 12% /var/lib/vservers/c /dev/loop0 4.4G 4.4G 0 100% /media/debian-6.0.0-amd64-DVD-1 /dev/loop1 4.4G 4.4G 0 100% /media/debian-6.0.0-i386-DVD-1 /dev/mapper/system--host-vs_d 74G 55G 16G 78% /var/lib/vservers/d root@kvmhost2:~# cat /proc/mounts rootfs / rootfs rw 0 0 none /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 none /proc proc rw,nosuid,nodev,noexec,relatime 0 0 none /dev devtmpfs rw,relatime,size=16500836k,nr_inodes=4125209,mode=755 0 0 none /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 /dev/mapper/system--host-root / ext3 rw,relatime,errors=remount-ro,data=ordered 0 0 tmpfs /lib/init/rw tmpfs rw,nosuid,relatime,mode=755 0 0 tmpfs /dev/shm tmpfs rw,nosuid,nodev,relatime 0 0 fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0 /dev/md0 /boot ext3 rw,sync,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-isos /srv/isos ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_a /var/lib/vservers/a ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_b /var/lib/vservers/b ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_c /var/lib/vservers/c ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/loop0 /media/debian-6.0.0-amd64-DVD-1 iso9660 ro,relatime 0 0 /dev/loop1 /media/debian-6.0.0-i386-DVD-1 iso9660 ro,relatime 0 0 /dev/mapper/system--host-vs_d /var/lib/vservers/d ext3 rw,relatime,errors=continue,data=ordered 0 0 root@kvmhost2:~# cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sda2[0] sdb2[1] 975779968 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 979840 blocks [2/2] [UU] unused devices: <none> root@kvmhost2:~# iostat -x Linux 2.6.32-5-vserver-amd64 (kvmhost2) 06/28/2012 _x86_64_ (8 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 3.09 0.14 2.92 1.51 0.00 92.35 Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 23.25 161.12 7.46 37.90 855.27 1596.62 54.05 0.13 2.80 1.76 8.00 sdb 22.82 161.36 7.36 37.66 850.29 1596.62 54.35 0.54 12.01 1.80 8.09 md0 0.00 0.00 0.00 0.00 0.14 0.02 38.44 0.00 0.00 0.00 0.00 md1 0.00 0.00 53.55 198.16 768.01 1585.25 9.35 0.00 0.00 0.00 0.00 dm-0 0.00 0.00 0.48 20.21 16.70 161.71 8.62 0.26 12.72 0.77 1.60 dm-1 0.00 0.00 3.62 10.03 28.94 80.21 8.00 0.19 13.68 1.59 2.17 dm-2 0.00 0.00 0.00 0.00 0.00 0.00 9.17 0.00 9.64 6.42 0.00 dm-3 0.00 0.00 6.73 0.41 53.87 3.28 8.00 0.02 3.44 0.12 0.09 dm-4 0.00 0.00 17.45 18.18 139.57 145.47 8.00 0.42 11.81 0.76 2.69 dm-5 0.00 0.00 2.50 46.38 120.50 371.07 10.06 0.69 14.20 0.46 2.26 dm-6 0.00 0.00 0.02 0.10 0.67 0.81 12.53 0.01 75.53 18.58 0.22 dm-7 0.00 0.00 0.00 0.00 0.00 0.00 7.99 0.00 11.24 9.45 0.00 dm-8 0.00 0.00 22.69 102.76 407.25 822.09 9.80 0.97 7.71 0.39 4.95 dm-9 0.00 0.00 0.06 0.08 0.50 0.62 8.00 0.07 481.23 11.72 0.16 root@kvmhost2:~# ls -l /dev/mapper/ total 0 crw------- 1 root root 10, 59 May 11 11:19 control lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm1 -> ../dm-4 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm2 -> ../dm-3 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-isos -> ../dm-2 lrwxrwxrwx 1 root root 7 May 11 11:19 system--host-root -> ../dm-0 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-swap -> ../dm-9 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_d -> ../dm-8 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_b -> ../dm-6 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_c -> ../dm-7 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_a -> ../dm-5 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm3 -> ../dm-1 root@kvmhost2:~#

• Mac won't boot into safe mode

  - by Stephen

  Mac boots fine normally, except when in safe mode. Holding down shift when booting gets me to the progress bar on the grey screen. Progress bar gets about half way before mac reboots. I modified nvram boot-args to get a better look: sudo nvram boot-args="-x -v" It definitely gets through fsck, skips loading kernel extensions (since it's in safe mode), does something with the network interfaces, then this is the last thing it wips through...

• CentOS - Add additional hard drive raid arrays on Dell Perc 5/i card

  - by Quanano

  We have a Dell Poweredge 2900 system with Dell Perc 5/i card and 4 SAS hard drives attached, with NTFS partitions on them. We installed CentOS on one raid array on this controller with a different controller and it is working fine. We are now trying to access the drives shown above and they are not being shown in /dev as sdb, etc. sda is the drive that we installed centos on and it has sda1, sda2, sda3, etc. The CDROM has been picked up as well. If I scan for scsi devices then the perc and adaptec controllers are both found. sg0 is the CDROM and sg2 is the centos installed, however I think sg1 is the other drive but I cannot see anyway to mount the partitions, as only the drive is listed in /dev. Thanks.

• How does this main domain have a CNAME record?

  I was under the impression that only subdomains could have CNAME records: main domains need to define all their own records. However, apt-get.com seems to have only a CNAME record.

• Why are my USB 2.0 devices crashing Windows XP?

  - by BenAlabaster

  Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

• Computer won't reboot without waiting for a while

  - by Benjamin

  I've got an unusual problem with my computer. When ever I reboot my computer it won't boot, I get a few beeps from the BIOS and nothing else, however if I wait for a few minuets the computer will boot perfectly. I tried to count the beeps and I get around 7-9 of them; the first two are noticeably closer together than the rest. [Edit: I'm now reasonably confident it's 1 long followed by 8 short beeps. That would be a display related issue: http://www.bioscentral.com/beepcodes/amibeep.htm] My BIOS is American Megatrends Inc and version P1.80, the Motherboard is an ASRock X58 Extreme (both according to dmidecode) Here's an output from LSPCI, I'm not sure what else might be useful but I can provide whatever's asked. 00:00.0 Host bridge: Intel Corporation 5520/5500/X58 I/O Hub to ESI Port (rev 13) 00:01.0 PCI bridge: Intel Corporation 5520/5500/X58 I/O Hub PCI Express Root Port 1 (rev 13) 00:03.0 PCI bridge: Intel Corporation 5520/5500/X58 I/O Hub PCI Express Root Port 3 (rev 13) 00:07.0 PCI bridge: Intel Corporation 5520/5500/X58 I/O Hub PCI Express Root Port 7 (rev 13) 00:14.0 PIC: Intel Corporation 5520/5500/X58 I/O Hub System Management Registers (rev 13) 00:14.1 PIC: Intel Corporation 5520/5500/X58 I/O Hub GPIO and Scratch Pad Registers (rev 13) 00:14.2 PIC: Intel Corporation 5520/5500/X58 I/O Hub Control Status and RAS Registers (rev 13) 00:14.3 PIC: Intel Corporation 5520/5500/X58 I/O Hub Throttle Registers (rev 13) 00:1a.0 USB controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #4 00:1a.1 USB controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #5 00:1a.2 USB controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #6 00:1a.7 USB controller: Intel Corporation 82801JI (ICH10 Family) USB2 EHCI Controller #2 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller 00:1c.0 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express Root Port 1 00:1c.1 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express Port 2 00:1c.5 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express Root Port 6 00:1d.0 USB controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #1 00:1d.1 USB controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #2 00:1d.2 USB controller: Intel Corporation 82801JI (ICH10 Family) USB UHCI Controller #3 00:1d.7 USB controller: Intel Corporation 82801JI (ICH10 Family) USB2 EHCI Controller #1 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 90) 00:1f.0 ISA bridge: Intel Corporation 82801JIR (ICH10R) LPC Interface Controller 00:1f.2 SATA controller: Intel Corporation 82801JI (ICH10 Family) SATA AHCI Controller 00:1f.3 SMBus: Intel Corporation 82801JI (ICH10 Family) SMBus Controller 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Screen Casting using ffmpeg (too fast)

  - by rowman

  I can use ffmpeg to make screen casts: ffmpeg -f x11grab -s 1280x800 -i :0.0 -c:v libx264 -framerate 30 -r 30 -crf 18 out.mkv However the output comes out to be too fast paced. It also happens with GTK RecordMyDesktop if I enable the encode on the fly. So, the questions is how to get a normal video pace.

• Unable to list contents/remove directory (linux ext3)

  - by RedKrieg

  System is CentOS5 x86_64, completely up to date. I've got a folder that can't be listed (ls just hangs, eating memory until it is killed). The directory size is nearly 500k: root@server [/home/user/public_html/domain.com/wp-content/uploads/2010/03]# stat . File: `.' Size: 458752 Blocks: 904 IO Block: 4096 directory Device: 812h/2066d Inode: 44499071 Links: 2 Access: (0755/drwxr-xr-x) Uid: ( 3292/ user) Gid: ( 3287/ user) Access: 2012-06-29 17:31:47.000000000 -0400 Modify: 2012-10-23 14:41:58.000000000 -0400 Change: 2012-10-23 14:41:58.000000000 -0400 I can see the file names if I use ls -1f, but it just repeats the same 48 files ad infinitum, all of which have non-ascii characters somewhere in the file name: La-critic\363-al-servicio-la-privacidad-300x160.jpg When I try to access the files (say to copy them or remove them) I get messages like the following: lstat("/home/user/public_html/domain.com/wp-content/uploads/2010/03/Sebast\355an-Pi\361era-el-balc\363n-150x120.jpg", 0x7fff364c52c0) = -1 ENOENT (No such file or directory) I tried altering the code found on this man page and modified the code to call unlink for each file. I get the same ENOENT error from the unlink call: unlink("/home/user/public_html/domain.com/wp-content/uploads/2010/03/Marca-naci\363n-Madrid-150x120.jpg") = -1 ENOENT (No such file or directory) I also straced a "touch", grabbed the syscalls it makes and replicated them, then tried to unlink the resulting file by name. This works fine, but the folder still contains an entry by the same name after the operation completes and the program runs for an arbitrarily long time (strace output ended up at 20GB after 5 minutes and I stopped the process). I'm stumped on this one, I'd really prefer not to have to take this production machine (hundreds of customers) offline to fsck the filesystem, but I'm leaning toward that being the only option at this point. If anyone's had success using other methods for removing files (by inode number, I can get those with the getdents code) I'd love to hear them. (Yes, I've tried find . -inum <inode> -exec rm -fv {} \; and it still has the problem with unlink returning ENOENT) For those interested, here's the diff between that man page's code and mine.

• I can connect to Samba server but cannot access shares.

  - by jlego

  I'm having trouble getting samba sharing working to access shares. I have setup a stand-alone box running Fedora 16 to use as a file-sharing and web development server. It needs to be able to share files with a Windows 7 PC and a Mac running OSX Snow Leopard. I've setup Samba using the Samba configuration GUI tool on Fedora. Added users to Fedora and connected them as Samba users (which are the same as the Windows and Mac usernames and passwords). The workgroup name is the same as the Windows workgroup. Authentication is set to User. I've allowed Samba and Samba client through the firewall and set the ethernet to a trusted port in the firewall. Both the Windows and Mac machines can connect to the server and view the shares, however when trying to access the shares, Windows throws error: 0x80070035 " Windows cannot access \\SERVERNAME\ShareName." Windows user is not prompted for a username or password when accessing the server (found under "Network Places"). This also happens when connecting with the IP rather than the server name. The Mac can also connect to the server and see the shares but when choosing a share gives the error: The original item for ShareName cannot be found. When connecting via IP, the Mac user is prompted for username and password, which when authenticated gives a list of shares, however when choosing a share to connect to, the error is displayed and the user cannot access the share. Since both machines are acting similarly when trying to access the shares, I assume it is an issue with how Samba is configured. smb.conf: [global] workgroup = workgroup server string = Server log file = /var/log/samba/log.%m max log size = 50 security = user load printers = yes cups options = raw printcap name = lpstat printing = cups [homes] comment = Home Directories browseable = no writable = yes [printers] comment = All Printers path = /var/spool/samba browseable = yes printable = yes [FileServ] comment = FileShare path = /media/FileServ read only = no browseable = yes valid users = user1, user2 [webdev] comment = Web development path = /var/www/html/webdev read only = no browseable = yes valid users = user1 How do I get samba sharing working? UPDATE: I Figured it out, it was because I was sharing a second hard drive. See checked answer below. Speculation 1: Before this box I had another box with the same version of fedora installed (16) and samba working for these same computers. I started up the old machine and copied the smb.conf file from the old machine to the new one (editing the share definitions for the new shares of course) and I still get the same errors on both client machines. The only difference in environment is the hardware and the router. On the old machine the router received a dynamic public IP and assigned dynamic private IPs to each device on the network while the new machine is connected to a router that has a static public IP (still dynamic internal IPs though.) Could either one of these be affecting Samba? Speculation 2: As the directory I am trying to share is actually an entire internal disk, I have tried these things: 1.) changing the owner of the mounted disk from root to my user (which is the same username as on the Windows machine) 2.) made a share that only included one of the folders on the disk instead of the entire disk with my user again as the owner. Both tests failed giving me the same errors regarding the network address. Speculation 3: Whenever I try to connect to the share on the Windows 7 client I am prompted for my username and password. When I enter the correct credentials I get an access denied message. However I did notice that under the login box "domain: WINDOWS-PC-NAME" is listed. I believe this could very well be the problem. Speculation 4: So I've completely reinstalled Fedora and Samba now. I've created a share on the first harddrive (one fedora is installed on) and I can access that fine from Windows. However when I try to share any data on the second disk, I am receiving the same error. This I believe is the problem. I think I need to change some things in fstab or fdisk or something. Speculation 5: So in fstab I mapped the drive to automount in a folder which works correctly. I also added the samba_share_t SElinux label to the mountpoint directory which now allows me to access the shares on the Windows machine, however I cannot see any of the files in the directory on the windows machine. (They are there, I can see them in the fedora file browser locally)

• Fixing predicated NSFetchedResultsController/NSFetchRequest performance with SQLite backend?

  - by Jaanus

  I have a series of NSFetchedResultsControllers powering some table views, and their performance on device was abysmal, on the order of seconds. Since it all runs on main thread, it's blocking my app at startup, which is not great. I investigated and turns out the predicate is the problem: NSPredicate *somePredicate = [NSPredicate predicateWithFormat:@"ANY somethings == %@", something]; [fetchRequest setPredicate:somePredicate]; I.e the fetch entity, call it "things", has a many-to-many relation with entity "something". This predicate is a filter that limits the results to only things that have a relation with a particular "something". When I removed the predicate for testing, fetch time (the initial performFetch: call) dropped (for some extreme cases) from 4 seconds to around 100ms or less, which is acceptable. I am troubled by this, though, as it negates a lot of the benefit I was hoping to gain with Core Data and NSFRC, which otherwise seems like a powerful tool. So, my question is, how can I optimize this performance? Am I using the predicate wrong? Should I modify the model/schema somehow? And what other ways there are to fix this? Is this kind of degraded performance to be expected? (There are on the order of hundreds of <1KB objects.) EDIT WITH DETAILS: Here's the code: [fetchRequest setFetchLimit:200]; NSLog(@"before fetch"); BOOL success = [frc performFetch:&error]; if (!success) { NSLog(@"Fetch request error: %@", error); } NSLog(@"after fetch"); Updated logs (previously, I had some application inefficiencies degrading the performance here. These are the updated logs that should be as close to optimal as you can get under my current environment): 2010-02-05 12:45:22.138 Special Ppl[429:207] before fetch 2010-02-05 12:45:22.144 Special Ppl[429:207] CoreData: sql: SELECT DISTINCT 0, t0.Z_PK, t0.Z_OPT, <model fields> FROM ZTHING t0 LEFT OUTER JOIN Z_1THINGS t1 ON t0.Z_PK = t1.Z_2THINGS WHERE t1.Z_1SOMETHINGS = ?

(Apart from going to a binary store where this becomes a non-issue, so I might do that. Binary store performance is consistently ~100ms for the above 200-object predicated query.) (I nested another question here previously, which I now moved away).

• Optimizing Jaro-Winkler algorithm

  - by Pentium10

  I have this code for Jaro-Winkler algorithm taken from this website. I need to run 150,000 times to get distance between differences. It takes a long time, as I run on an Android mobile device. Can it be optimized more? public class Jaro { /** * gets the similarity of the two strings using Jaro distance. * * @param string1 the first input string * @param string2 the second input string * @return a value between 0-1 of the similarity */ public float getSimilarity(final String string1, final String string2) { //get half the length of the string rounded up - (this is the distance used for acceptable transpositions) final int halflen = ((Math.min(string1.length(), string2.length())) / 2) + ((Math.min(string1.length(), string2.length())) % 2); //get common characters final StringBuffer common1 = getCommonCharacters(string1, string2, halflen); final StringBuffer common2 = getCommonCharacters(string2, string1, halflen); //check for zero in common if (common1.length() == 0 || common2.length() == 0) { return 0.0f; } //check for same length common strings returning 0.0f is not the same if (common1.length() != common2.length()) { return 0.0f; } //get the number of transpositions int transpositions = 0; int n=common1.length(); for (int i = 0; i < n; i++) { if (common1.charAt(i) != common2.charAt(i)) transpositions++; } transpositions /= 2.0f; //calculate jaro metric return (common1.length() / ((float) string1.length()) + common2.length() / ((float) string2.length()) + (common1.length() - transpositions) / ((float) common1.length())) / 3.0f; } /** * returns a string buffer of characters from string1 within string2 if they are of a given * distance seperation from the position in string1. * * @param string1 * @param string2 * @param distanceSep * @return a string buffer of characters from string1 within string2 if they are of a given * distance seperation from the position in string1 */ private static StringBuffer getCommonCharacters(final String string1, final String string2, final int distanceSep) { //create a return buffer of characters final StringBuffer returnCommons = new StringBuffer(); //create a copy of string2 for processing final StringBuffer copy = new StringBuffer(string2); //iterate over string1 int n=string1.length(); int m=string2.length(); for (int i = 0; i < n; i++) { final char ch = string1.charAt(i); //set boolean for quick loop exit if found boolean foundIt = false; //compare char with range of characters to either side for (int j = Math.max(0, i - distanceSep); !foundIt && j < Math.min(i + distanceSep, m - 1); j++) { //check if found if (copy.charAt(j) == ch) { foundIt = true; //append character found returnCommons.append(ch); //alter copied string2 for processing copy.setCharAt(j, (char)0); } } } return returnCommons; } } I mention that in the whole process I make just instance of the script, so only once jaro= new Jaro(); If you are going to test and need examples so not break the script, you will find it here, in another thread for python optimization.

• How to fix notifyDataSetChanged/ListView problems in dynamic Adapter wrapper Android

  - by ipaterson

  Summary: Trying to dynamically add heading rows to a ListView via a custom adapter wrapper. ListView is having trouble keeping the scroll position in sync. Runnable demo project provided. I would like to dynamically add items to a list based on the values in a CursorAdapter, several positions ahead of what the user is currently viewing. To do this, I have an adapter that wraps the CursorAdapter and keeps the new content indexed in a SparseArray. The ListView needs to be updated when items are added to the custom adapter, but I have met a lot of pitfalls trying to get that to work and would love some advice. The demo project can be downloaded here: http://dl.dropbox.com/u/15334423/DynamicSectionedList.zip In the demo, the headings are added dynamically by looking ahead 10 places to find the correct position where the list items switch to the next letter. Each implementation of notifyDataSetChanged has problems as described: Demo 1 This demo shows the importance of notifyDataSetChanged(). On clicking anything, the app will crash. This is due to some sanity checking in ListView... mItemCount != adapter.getItemCount(). Moral is, we need to notify the list that data has changed. Demo 2 The natural next step is to notify the ListView of changes when changes occur. Unfortunately, doing so while the ListView is scrolling firmly breaks all touch interaction until the app switches out of touch mode. You will need to "fling scroll" far enough to generate new headings in order to notice this. Tapping the screen will not cause the scroll to stop, and once stopped none of the list items will be clickable. This is due to some if (!mDataChanged) { /* do very important stuff */ } code in AbsListView.onTouchEvent(). Demo 3 To fix this, Demo 3 introduces a pendingChanges flag and the custom Adapter gains a notifyDataSetChangedIfNeeded() which can be called by the ListView once it has entered a "safe" state for changes. The first point where changes must be notified is in ListView.layoutChildren(), so I overrode that method to first notify of changes if needed, then call through. Fling past at least one heading then click a list item. This doesn't quite work right, though I'm not totally sure why. Tapping or selecting an item with the keyboard/trackball causes the list to refresh without properly syncing the old position. It scrolls to the top of the list which is not acceptable. Demo 4 The scroll problem in Demo 3 can be conquered, at least in touch mode. By adding a call to notifyDataSetChangedIfNeeded() on touch down, the data change happens to take place at such a time that all touch interaction works as expected and the list position is properly synced. However, I can't find an analog for that when the device is not in touch mode, not to mention the fact that it definitely seems like a hack. The list almost always scrolls back to the top, I can't find out what causes it to occasionally maintain the correct position. Since Android is fighting me at each step of the way, I feel like there should be a better approach. Please try the demo, if any fixes can be applied to get it working that would be great! Many thanks to anyone who can look into this, hopefully if we can get the code working it will be useful for others trying to accomplish the same optimization for lists with headings.

• Microsoft SyncFramework - Sync different tables into one

  - by evnu

  Hello, we are trying to get the Microsoft SyncFramework running in our application to synchronize an oracle db with a mobile device. Problem The queries that we need to gather the data on the oracle db take much time (and we haven't found a way to speed them up yet), so we try to split them up in as much portions as possible. One big part of the whole problem is, that we need different information out of one big table, that bloats a query if combined. Unfortunately, the SyncFramework allows only one TableAdapter per SyncTable. Now this is a problem for our application: If we were able to use more than one TableAdapter per SyncTable, we could easily spread the queries in a more efficient way. Using one query per Table which combines all the needed data takes way too much time. Ideas I thought of creating different TableAdapters for each one of the required queries and then merge the resulting datasets afterwards (preferably on the server). This seems to work, but is a rather awkward solution. Does someone of you know a better solution? Or do you have some ideas that could help? Thanks in advance, evnu EDIT: So, I implemented the merge solution. If you are interested, take a look at the following code. I'll give more details if there are questions. <WebMethod()> _ Public Function GetChanges(ByVal groupMetadata As SyncGroupMetadata, ByVal syncSession As SyncSession) As SyncContext Dim stream As MemoryStream Dim format As BinaryFormatter = New BinaryFormatter Dim anchors As Dictionary(Of String, Byte()) ' keep track of the tables that will be updated Dim addTables As Dictionary(Of String, List(Of SyncTableMetadata)) = New Dictionary(Of String, List(Of SyncTableMetadata)) ' list of all present anchors Dim allAnchors As Dictionary(Of String, Byte()) = New Dictionary(Of String, Byte()) ' fill allAnchors - deserialize all given anchors For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata If Table.LastReceivedAnchor Is Nothing Or Table.LastReceivedAnchor.IsNull Then Continue For stream = New MemoryStream(Table.LastReceivedAnchor.Anchor) anchors = format.Deserialize(stream) For Each item As KeyValuePair(Of String, Byte()) In anchors allAnchors.Add(item.Key, item.Value) Next stream.Dispose() Next For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata If allAnchors.ContainsKey(Table.TableName) Then Table.LastReceivedAnchor.Anchor = allAnchors(Table.TableName) End If Dim addSyncTables As List(Of SyncTableMetadata) If syncSession.SyncParameters.Contains(Table.TableName) Then Dim tableNames() As String = syncSession.SyncParameters(Table.TableName).Value.ToString.Split(":") addSyncTables = New List(Of SyncTableMetadata) For Each tableName As String In tableNames Dim newSynctable As SyncTableMetadata = New SyncTableMetadata newSynctable.TableName = tableName If allAnchors.ContainsKey(tableName) Then Dim anker As SyncAnchor = New SyncAnchor(allAnchors(tableName)) newSynctable.LastReceivedAnchor = anker Else newSynctable.LastReceivedAnchor = Nothing End If newSynctable.SyncDirection = Table.SyncDirection addSyncTables.Add(newSynctable) Next addTables.Add(Table.TableName, addSyncTables) End If Next ' add the newly created synctables For Each item As KeyValuePair(Of String, List(Of SyncTableMetadata)) In addTables For Each Table As SyncTableMetadata In item.Value groupMetadata.TablesMetadata.Add(Table) Next Next ' fire queries Dim context As SyncContext = servSyncProvider.GetChanges(groupMetadata, syncSession) ' merge resulting datasets For Each item As KeyValuePair(Of String, List(Of SyncTableMetadata)) In addTables For Each Table As SyncTableMetadata In item.Value If context.DataSet.Tables.Contains(Table.TableName) Then If Not context.DataSet.Tables.Contains(item.Key) Then Dim tmp As DataTable = context.DataSet.Tables(Table.TableName).Copy tmp.TableName = item.Key context.DataSet.Tables.Add(tmp) Else context.DataSet.Tables(item.Key).Merge(context.DataSet.Tables(Table.TableName)) context.DataSet.Tables.Remove(Table.TableName) End If End If Next Next ' create new anchors Dim allAnchorsDict As Dictionary(Of String, Byte()) = New Dictionary(Of String, Byte()) For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata allAnchorsDict.Add(Table.TableName, context.NewAnchor.Anchor) Next stream = New MemoryStream format.Serialize(stream, allAnchorsDict) context.NewAnchor.Anchor = stream.ToArray stream.Dispose() Return context End Function

• Windows CE Programming Serial Port - Getting Garbled Output

  - by user576639

  I am programming a Windows CE 6 device (Motorola MC3100 scanner Terminal). Using Lazarus FPC to compile it. After 3 weeks work I reluctantly post here in the hope someone can suggest why I am getting garbled output from the serial port. The code I am using is posted below. This is the standard code I have found from several places. The OpenPort works OK. When I send the string using SendString('ABCDEF') I get garbled input to the PC Serial port such as: 4[#131][#26][#0][#0][#0][#0] (the bracketed data indicates that it is a non-printable character ASCII Code) Obviously it is connecting to the port OK AND it is sending the correct no of characters (7). I have tried all combinations of Baud Rate, Data Bits, Parity and Stop Bits without any joy. Also tried changing cable, on a different PC etc. Could it be I need to set something else in the DCB? Any help or suggestions would be GREATLY appreciated. unit Unit1; {$mode objfpc}{$H+} interface uses Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls, ExtCtrls, Windows, LResources; type { TForm1 } TForm1 = class(TForm) Button1: TButton; Button2: TButton; Label1: TLabel; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); function OpenPort(ComPort:String;BaudRate,ByteSize,Parity,StopBits:integer):String; procedure SendString(str:String); private { private declarations } public { public declarations } end; var Form1: TForm1; cc:TCOMMCONFIG; Connected:Boolean; implementation {$R *.lfm} var F: TextFile; var hComm: THandle; str: String; lrc: LongWord; { TForm1 } function OpenPort(ComPort:String;BaudRate,ByteSize,Parity,StopBits:integer):String; var cc:TCOMMCONFIG; SWide:WideString; Port:LPCWSTR; begin SWide:=ComPort; Port:=PWideChar(SWide); result:=''; if (1=1) then begin Connected:=False; hComm:=CreateFile(Port, GENERIC_READ or GENERIC_WRITE,0, nil,OPEN_EXISTING,0,0); if (hComm = INVALID_HANDLE_VALUE) then begin ShowMessage('Fail to Open'); exit; end; GetCommState(hComm,cc.dcb); cc.dcb.BaudRate:=BaudRate; cc.dcb.ByteSize:=ByteSize; cc.dcb.Parity:=Parity; cc.dcb.StopBits:=StopBits; if not SetCommState(hComm, cc.dcb) then begin result:='SetCommState Error!'; CloseHandle(hComm); exit; end; Connected:=True; end; end; procedure TForm1.Button1Click(Sender: TObject); begin OpenPort('COM1:',9600,8,0,0); end; procedure TForm1.Button2Click(Sender: TObject); begin SendString('ABCDEFG'); end; procedure TForm1.SendString(str:String); var lrc:LongWord; begin if (hComm=0) then exit; try if not PurgeComm(hComm, PURGE_TXABORT or PURGE_TXCLEAR) then raise Exception.Create('Unable to purge com: '); except Exit; end; WriteFile(hComm,str,Length(str), lrc, nil); end; end.

• Results Delphi users who wish to use HID USB in windows

  - by Lex Dean

  Results Delphi users who wish to use HID USB in windows HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB Contain a list if keys containing vender ID and Producer ID numbers that co inside with the USB web sites data base. These numbers and the GUID held within the key gives important information to execute the HID.dll that is otherwise imposable to execute. The Control Panel/System/Hardware/Device manager/USB Serial Bus Controllers/Mass Storage Devices/details simply lists the registry data. The access to the programmer has been documented through the API32.dll with a number of procedures that accesses the registry. But that is not the problem yet it looks like the problem!!!!!!!!! The key is info about the registry and how to use it. These keys are viewed in RegEdit.exe it’s self. Some parts of the registry like the USB have been given a windows security system type of protection with a Aurthz.dll to give the USB read and right protection. Even the api32.dll. Now only Microsoft give out these details and we all know Microsoft hate Delphi. Now C users have enjoyed this access for over 10 years now. Now some will make out that you should never give out such information because some idiot may make a stupid virus (true), but the argument is also do Delphi users need to be denied USB access for another ten years!!!!!!!!!!!!. What I do not have is the skill in is assembly code. I’m seeking for some one that can trace how regedit.exe gets its access through Aurthz.dll to access the USB data. So I’m asking all who reads this:- to partition any friend they have that has this skill to get the Aurthz.dll info needed. I find communicating with USB.org they reply when they have a positive email reply but do not bother should their email be a slightly negative policy. For all simple reasoning, all that USB had to do was to have a secure key as they have done, and to update the same data into a unsecured key every time the data is changed for USB developer to access. And not bother developers access to Aurthz.dll. Authz.dll with these functions for USB:- AuthzFreeResourceManager AuthzFreeContext AuthzAccessCheck(Flags: DWORD; AuthzClientContext: AUTHZ_CLIENT_CONTEXT_HANDLE; pRequest: PAUTHZ_ACCESS_REQUEST; AuditInfo: AUTHZ_AUDIT_INFO_HANDLE; pSecurityDescriptor: PSECURITY_DESCRIPTOR; OptionalSecurityDescriptorArray: PSECURITY_DESCRIPTOR; OptionalSecurityDescriptorCount: DWORD; //OPTIONAL, Var pReply: AUTHZ_ACCESS_REPLY; pAuthzHandle: PAUTHZ_ACCESS_CHECK_RESULTS_HANDLE): BOOl; AuthzInitializeContextFromSid(Flags: DWORD; UserSid: PSID; AuthzResourceManager: AUTHZ_RESOURCE_MANAGER_HANDLE; pExpirationTime: int64; Identifier: LUID; DynamicGroupArgs: PVOID; pAuthzClientContext: PAUTHZ_CLIENT_CONTEXT_HANDLE): BOOL; AuthzInitializeResourceManager(flags: DWORD; pfnAccessCheck: PFN_AUTHZ_DYNAMIC_ACCESS_CHECK; pfnComputeDynamicGroups: PFN_AUTHZ_COMPUTE_DYNAMIC_GROUPS; pfnFreeDynamicGroups: PFN_AUTHZ_FREE_DYNAMIC_GROUPS; ResourceManagerName: PWideChar; pAuthzResourceManager: PAUTHZ_RESOURCE_MANAGER_HANDLE): BOOL; further in Authz.h on kolers.com J Lex Dean.

• Joystick input in Java

  - by typoknig

  Hi all, I am making a 2D game in Java and I want to use a joystick to control the movement of some crosshairs. Right now I have it so the mouse can control those crosshairs. My only criteria for this is that the control for the crosshair must stay in the game window unless a user clicks off into another window. Basically I want my game to capture whatever device is controlling the crosshairs much like a virtual machine captures a mouse. The joystick I am using (Thrustmaster Hotas Cougar) comes with some pretty advanced features, so that may make this easier (or harder). I have tried the solution listed on this page, but I am using a 64bit computer and for some reason it does not like that. I have also tried to use the key emulation feature of my joystick, but with little success. Here is what I have so far, any pointer would be appreciated. Main Class: import java.awt.Color; import java.awt.Cursor; import java.awt.event.MouseEvent; import java.awt.event.MouseMotionListener; import java.awt.Graphics; import java.awt.Image; import java.awt.image.BufferStrategy; import java.awt.image.MemoryImageSource; import java.awt.Point; import java.awt.Toolkit; import javax.swing.JFrame; public class Game extends JFrame implements MouseMotionListener{ private int windowWidth = 1280; private int windowHeight = 1024; private Crosshair crosshair; public static void main(String[] args) { new Game(); } public Game() { this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setSize(windowWidth, windowHeight); this.setResizable(false); this.setLocation(0,0); this.setVisible(true); this.createBufferStrategy(2); addMouseMotionListener(this); initGame(); while(true) { long start = System.currentTimeMillis(); gameLoop(); while(System.currentTimeMillis()-start < 5) { //empty while loop } } } private void initGame() { hideCursor(); crosshair = new Crosshair (windowWidth/2, windowHeight/2); } private void gameLoop() { //game logic drawFrame(); } private void drawFrame() { BufferStrategy bf = this.getBufferStrategy(); Graphics g = (Graphics)bf.getDrawGraphics(); try { g = bf.getDrawGraphics(); Color darkBlue = new Color(0x010040); g.setColor(darkBlue); g.fillRect(0, 0, windowWidth, windowHeight); drawCrossHair(g); } finally { g.dispose(); } bf.show(); Toolkit.getDefaultToolkit().sync(); } private void drawCrossHair(Graphics g){ Color yellow = new Color (0xEDFF62); g.setColor(yellow); g.drawOval(crosshair.x, crosshair.y, 40, 40); g.fillArc(crosshair.x + 10, crosshair.y + 21 , 20, 20, -45, -90); g.fillArc(crosshair.x - 1, crosshair.y + 10, 20, 20, -135, -90); g.fillArc(crosshair.x + 10, crosshair.y - 1, 20, 20, -225, -90); g.fillArc(crosshair.x + 21, crosshair.y + 10, 20, 20, -315, -90); } @Override public void mouseDragged(MouseEvent e) { //empty method } @Override public void mouseMoved(MouseEvent e) { crosshair.x = e.getX(); crosshair.y = e.getY(); } private void hideCursor() { int[] pixels = new int[16 * 16]; Image image = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(16, 16, pixels, 0, 16)); Cursor transparentCursor = Toolkit.getDefaultToolkit().createCustomCursor(image, new Point(0, 0), "invisiblecursor"); getContentPane().setCursor(transparentCursor); } } Another Class: public class Crosshair{ public int x; public int y; public Crosshair(int x, int y) { this.x = x; this.y = y; } }

• VFP Unit Matrix Multiply problem on the iPhone

  - by Ian Copland

  Hi. I'm trying to write a Matrix3x3 multiply using the Vector Floating Point on the iPhone, however i'm encountering some problems. This is my first attempt at writing any ARM assembly, so it could be a faily simple solution that i'm not seeing. I've currently got a small application running using a maths library that i've written. I'm investigating into the benifits using the Vector Floating Point Unit would provide so i've taken my matrix multiply and converted it to asm. Previously the application would run without a problem, however now my objects will all randomly disappear. This seems to be caused by the results from my matrix multiply becoming NAN at some point. Heres the code IMatrix3x3 operator*(IMatrix3x3 & _A, IMatrix3x3 & _B) { IMatrix3x3 C; //C++ code for the simulator #if TARGET_IPHONE_SIMULATOR == true C.A0 = _A.A0 * _B.A0 + _A.A1 * _B.B0 + _A.A2 * _B.C0; C.A1 = _A.A0 * _B.A1 + _A.A1 * _B.B1 + _A.A2 * _B.C1; C.A2 = _A.A0 * _B.A2 + _A.A1 * _B.B2 + _A.A2 * _B.C2; C.B0 = _A.B0 * _B.A0 + _A.B1 * _B.B0 + _A.B2 * _B.C0; C.B1 = _A.B0 * _B.A1 + _A.B1 * _B.B1 + _A.B2 * _B.C1; C.B2 = _A.B0 * _B.A2 + _A.B1 * _B.B2 + _A.B2 * _B.C2; C.C0 = _A.C0 * _B.A0 + _A.C1 * _B.B0 + _A.C2 * _B.C0; C.C1 = _A.C0 * _B.A1 + _A.C1 * _B.B1 + _A.C2 * _B.C1; C.C2 = _A.C0 * _B.A2 + _A.C1 * _B.B2 + _A.C2 * _B.C2; //VPU ARM asm for the device #else //create a pointer to the Matrices IMatrix3x3 * pA = &_A; IMatrix3x3 * pB = &_B; IMatrix3x3 * pC = &C; //asm code asm volatile( //turn on a vector depth of 3 "fmrx r0, fpscr \n\t" "bic r0, r0, #0x00370000 \n\t" "orr r0, r0, #0x00020000 \n\t" "fmxr fpscr, r0 \n\t" //load matrix B into the vector bank "fldmias %1, {s8-s16} \n\t" //load the first row of A into the scalar bank "fldmias %0!, {s0-s2} \n\t" //calulate C.A0, C.A1 and C.A2 "fmuls s17, s8, s0 \n\t" "fmacs s17, s11, s1 \n\t" "fmacs s17, s14, s2 \n\t" //save this into the output "fstmias %2!, {s17-s19} \n\t" //load the second row of A into the scalar bank "fldmias %0!, {s0-s2} \n\t" //calulate C.B0, C.B1 and C.B2 "fmuls s17, s8, s0 \n\t" "fmacs s17, s11, s1 \n\t" "fmacs s17, s14, s2 \n\t" //save this into the output "fstmias %2!, {s17-s19} \n\t" //load the third row of A into the scalar bank "fldmias %0!, {s0-s2} \n\t" //calulate C.C0, C.C1 and C.C2 "fmuls s17, s8, s0 \n\t" "fmacs s17, s11, s1 \n\t" "fmacs s17, s14, s2 \n\t" //save this into the output "fstmias %2!, {s17-s19} \n\t" //set the vector depth back to 1 "fmrx r0, fpscr \n\t" "bic r0, r0, #0x00370000 \n\t" "orr r0, r0, #0x00000000 \n\t" "fmxr fpscr, r0 \n\t" //pass the inputs and set the clobber list : "+r"(pA), "+r"(pB), "+r" (pC) : :"cc", "memory","s0", "s1", "s2", "s8", "s9", "s10", "s11", "s12", "s13", "s14", "s15", "s16", "s17", "s18", "s19" ); #endif return C; } As far as i can see that makes sence. While debugging i've managed to notice that if i were to say _A = C prior to the return and after the ASM, _A will not necessarily be equal to C which has only increased my confusion. I had thought it was possibly due to the pointers I'm giving to the VFPU being incrimented by lines such as "fldmias %0!, {s0-s2} \n\t" however my understanding of asm is not good enough to properly understand the problem, nor to see an alternative approach to that line of code. Anyway, I was hoping someone with a greater understanding than me would be able to see a solution, and any help would be greatly appreciated, thank you :-)

• How do I use UIImagePickerController just to display the camera and not take a picture?

  - by Thomas

  Hello All: I'd like to know how to open the camera inside of a pre-defined frame (not the entire screen). When the view loads, I have a box, and inside it, I want to display what the camera sees. I don't want to snap a picture, just basically use the camera as a viewfinder. I have searched this site and have not yet found what I'm looking for. Please help. Thanks! Thomas Update 1: Here is what I have tried so far. 1.) I added UIImageView to my xib. 2.) Connect the following outlet to the UIImageView in IB IBOutlet UIImageView *cameraWindow; 3.) I put the following code in viewWillAppear -(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES]; NSLog(@"viewWillAppear ran"); } But this method does not run, as evident by the absence of NSLog statement from my console. Please help! Thanks, Thomas Update 2: OK I got it to run by putting the code in viewDidLoad but my camera still doesn't show up...any suggestions? Anyone....? I've been reading the UIImagePickerController class reference, but am kinda unsure how to make sense of it. I'm still learning iPhone, so it's a bit of a struggle. Please help! - (void)viewDidLoad { [super viewDidLoad]; // Create a bool variable "camera" and call isSourceTypeAvailable to see if camera exists on device BOOL camera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]; // If there is a camera, then display the world throught the viewfinder if(camera) { UIImagePickerController *picker = [[UIImagePickerController alloc] init]; // Since I'm not actually taking a picture, is a delegate function necessary? picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES]; NSLog(@"Camera is available"); } // Otherwise, do nothing. else NSLog(@"No camera available"); } Thanks! Thomas Update 3: A-HA! Found this on the Apple Class Reference. Discussion The delegate receives notifications when the user picks an image or movie, or exits the picker interface. The delegate also decides when to dismiss the picker interface, so you must provide a delegate to use a picker. If this property is nil, the picker is dismissed immediately if you try to show it. Gonna play around with the delegate now. Then I'm going to read on wtf a delegate is. Backwards? Whatever :-p Update 4: The two delegate functions for the class are – imagePickerController:didFinishPickingMediaWithInfo: – imagePickerControllerDidCancel: and since I don't actually want to pick an image or give the user the option to cancel, I am just defining the methods. They should never run though....I think.

• iPhone UIWebView local resources using Javascript and handling onorientationChange

  - by Dougnukem

  I'm trying to server HTML Javascript and CSS content from an iPhone application's local resources, and I'm having trouble handling onOrientationChange events and including external Javascript. I seem to be able to link in CSS properly but not javascript. I'm trying to use the following example of handling onOrientationChange (How to build an iPhone website) but I'm serving the webpage from my app's NSBundle mainBundle. I tried attaching a javascript function to body.onorientationchange and to window.onorientationchange but neither work when served from UIWebView locally (or remotely), but it works if I'm using the iPhone Safari. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>How to build an iPhone website</title> <meta name="author" content="will" /> <meta name="copyright" content="copyright 2008 www.engageinteractive.co.uk" /> <meta name="description" content="Welcome to engege interactive on the iPhone!" /> <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;"> <link rel="apple-touch-icon" href="images/template/engage.png"/> <style type="text/css"> @import url("iphone.css"); </style> <!-- <script type="text/javascript" src="orientation.js"></script> --> <script type="text/javascript"> function updateOrientation(){ try { var contentType = "show_normal"; switch(window.orientation){ case 0: contentType = "show_normal"; break; case -90: contentType = "show_right"; break; case 90: contentType = "show_left"; break; case 180: contentType = "show_flipped"; break; } document.getElementById("page_wrapper").setAttribute("class", contentType); //alert('ORIENTATION: ' + contentType); } catch(e) { alert('ERROR:' + e.message); } } window.onload = function initialLoad(){ try { loaded(); updateOrientation(); } catch(e) { alert('ERROR:' + e.message); } } function loaded() { document.getElementById("page_wrapper").style.visibility = "visible"; } </script> </head> <body onorientationchange="updateOrientation();"> <div id="page_wrapper"> <h1>Engage Interactive</h1> <div id="content_left"> <p>You are now holding your phone to the left</p> </div> <div id="content_right"> <p>You are now holding your phone to the right</p> </div> <div id="content_normal"> <p>You are now holding your phone upright</p> </div> <div id="content_flipped"> <p>This doesn't work yet, but there is a chance apple will enable it at some point, so I've put it in anyway.

No memory leaks, the crashes clearly are triggered in 32 bit mode only just after start inside the AppKit itself like deep inside NSThread sleep's callstack.

• FormatException with IsolatedStorageSettings

  - by Jurgen Camilleri

  I have a problem when serializing a Dictionary<string,Person> to IsolatedStorageSettings. I'm doing the following: public Dictionary<string, Person> Names = new Dictionary<string, Person>(); if (!IsolatedStorageSettings.ApplicationSettings.Contains("Names")) { //Add to dictionary Names.Add("key", new Person(false, new System.Device.Location.GeoCoordinate(0, 0), new List<GeoCoordinate>() { new GeoCoordinate(35.8974, 14.5099), new GeoCoordinate(35.8974, 14.5099), new GeoCoordinate(35.8973, 14.5100), new GeoCoordinate(35.8973, 14.5099) })); //Serialize dictionary to IsolatedStorage IsolatedStorageSettings.ApplicationSettings.Add("Names", Names); IsolatedStorageSettings.ApplicationSettings.Save(); } Here is my Person class: [DataContract] public class Person { [DataMember] public bool Unlocked { get; set; } [DataMember] public GeoCoordinate Location { get; set; } [DataMember] public List<GeoCoordinate> Bounds { get; set; } public Person(bool unlocked, GeoCoordinate location, List<GeoCoordinate> bounds) { this.Unlocked = unlocked; this.Location = location; this.Bounds = bounds; } } The code works the first time, however on the second run I get a System.FormatException at the if condition. Any help would be highly appreciated thanks. P.S.: I tried an IsolatedStorageSettings.ApplicationSettings.Clear() but the call to Clear also gives a FormatException. I have found something new...the exception occurs twenty-five times, or at least that's how many times it shows up in the Output window. However after that, the data is deserialized perfectly. Should I be worried about the exceptions if they do not stop the execution of the program? EDIT: Here's the call stack when the exception occurs: mscorlib.dll!double.Parse(string s, System.Globalization.NumberStyles style, System.IFormatProvider provider) + 0x17 bytes System.Xml.dll!System.Xml.XmlConvert.ToDouble(string s) + 0x4b bytes System.Xml.dll!System.Xml.XmlReader.ReadContentAsDouble() + 0x1f bytes System.Runtime.Serialization.dll!System.Xml.XmlDictionaryReader.XmlWrappedReader.ReadContentAsDouble() + 0xb bytes System.Runtime.Serialization.dll!System.Xml.XmlDictionaryReader.ReadElementContentAsDouble() + 0x35 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlReaderDelegator.ReadElementContentAsDouble() + 0x19 bytes mscorlib.dll!System.Reflection.RuntimeMethodInfo.InternalInvoke(System.Reflection.RuntimeMethodInfo rtmi, object obj, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder binder, object parameters, System.Globalization.CultureInfo culture, bool isBinderDefault, System.Reflection.Assembly caller, bool verifyAccess, ref System.Threading.StackCrawlMark stackMark) mscorlib.dll!System.Reflection.RuntimeMethodInfo.InternalInvoke(object obj, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder binder, object[] parameters, System.Globalization.CultureInfo culture, ref System.Threading.StackCrawlMark stackMark) + 0x168 bytes mscorlib.dll!System.Reflection.MethodBase.Invoke(object obj, object[] parameters) + 0xa bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlFormatReader.ReadValue(System.Type type, string name, string ns, System.Runtime.Serialization.XmlObjectSerializerReadContext context, System.Runtime.Serialization.XmlReaderDelegator xmlReader) + 0x138 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlFormatReader.ReadMemberAtMemberIndex(System.Runtime.Serialization.ClassDataContract classContract, ref object objectLocal, System.Runtime.Serialization.DeserializedObject desObj) + 0xc4 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlFormatReader.ReadClass(System.Runtime.Serialization.DeserializedObject desObj, System.Runtime.Serialization.ClassDataContract classContract, int membersRead) + 0xf3 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlFormatReader.Deserialize(System.Runtime.Serialization.XmlObjectSerializerReadContext context) + 0x36 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlFormatReader.InitializeCallStack(System.Runtime.Serialization.DataContract clContract, System.Runtime.Serialization.XmlReaderDelegator xmlReaderDelegator, System.Runtime.Serialization.XmlObjectSerializerReadContext xmlObjContext, System.Xml.XmlDictionaryString[] memberNamesColl, System.Xml.XmlDictionaryString[] memberNamespacesColl) + 0x77 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.CollectionDataContract.ReadXmlValue(System.Runtime.Serialization.XmlReaderDelegator xmlReader, System.Runtime.Serialization.XmlObjectSerializerReadContext context) + 0x5d bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlObjectSerializerReadContext.ReadDataContractValue(System.Runtime.Serialization.DataContract dataContract, System.Runtime.Serialization.XmlReaderDelegator reader) + 0x3 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlObjectSerializerReadContext.InternalDeserialize(System.Runtime.Serialization.XmlReaderDelegator reader, string name, string ns, ref System.Runtime.Serialization.DataContract dataContract) + 0x10e bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlObjectSerializerReadContext.InternalDeserialize(System.Runtime.Serialization.XmlReaderDelegator xmlReader, System.Type declaredType, System.Runtime.Serialization.DataContract dataContract, string name, string ns) + 0xb bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.DataContractSerializer.InternalReadObject(System.Runtime.Serialization.XmlReaderDelegator xmlReader, bool verifyObjectName) + 0x124 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlObjectSerializer.ReadObjectHandleExceptions(System.Runtime.Serialization.XmlReaderDelegator reader, bool verifyObjectName) + 0xe bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlObjectSerializer.ReadObject(System.Xml.XmlDictionaryReader reader) + 0x7 bytes System.Runtime.Serialization.dll!System.Runtime.Serialization.XmlObjectSerializer.ReadObject(System.IO.Stream stream) + 0x17 bytes System.Windows.dll!System.IO.IsolatedStorage.IsolatedStorageSettings.Reload() + 0xa3 bytes System.Windows.dll!System.IO.IsolatedStorage.IsolatedStorageSettings.IsolatedStorageSettings(bool useSiteSettings) + 0x20 bytes System.Windows.dll!System.IO.IsolatedStorage.IsolatedStorageSettings.ApplicationSettings.get() + 0xd bytes
