• Centos 6.2 postfix install dependency issues

  - by Mishari

  I am administrating a VPS running cPanel and I'm trying to install postfix. Redhat-release says the version is CentOS release 6.2 (Final) and uname -a says: Linux server.mydomain.com 2.6.32-220.el6.i686 #1 SMP Tue Dec 6 16:15:40 GMT 2011 i686 i686 i386 GNU/Linux This is how I'm installing postfix (I had tried to solve the problem earlier by installing epel). # yum install postfix Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * epel: mirror.cogentco.com Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package postfix.i686 2:2.6.6-2.2.el6_1 will be installed --> Processing Dependency: mysql-libs for package: 2:postfix-2.6.6-2.2.el6_1.i686 --> Finished Dependency Resolution Error: Package: 2:postfix-2.6.6-2.2.el6_1.i686 (centos-burstnet) Requires: mysql-libs You could try using --skip-broken to work around the problem Attempts to install mysql-libs tells me several files conflict with "MySQL-server-5.1.61-0.glibc23.i386" I'm not sure why or how this is happening, does anyone know how to resolve this? Surely Centos 6.2 could not have shipped with a broken postfix.

• Slow connection to Linux MySQL from Windows only (XAMPP)

  - by Josh

  I'm having a problem with a PHP project (using Kohana 3.2 framework) on my Windows 7 64-bit machine connecting to the database. The development database is stored on a Ubuntu Linux server on the local network. Other development machines running OSX and Linux are connecting fine. There are no other Windows development machines to test with. I can access MySQL fine using MySQL Workbench, and other projects (which I believe to be less database heavy) run mostly ok, only occasionally getting timeout messages. I'm constantly getting Maximum execution time of 30 seconds exceeded when functions such as mysql_query() are run in this particular project. Specifically, the Kohana file where the timeout occurs is MODPATH\database\classes\kohana\database\mysql.php [ 186 ]. My local set-up is: Windows 7 Professional 64bit XAMPP 1.7.7 (PHP 5.3.8) The output of uname -a of the Linux server is: Linux peach 2.6.38-11-server #50-Ubuntu SMP Mon Sep 12 21:34:27 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I've tried the following, with no success: Disabling Windows firewall Switching between using a persistant and normal connection In my.cnf, adding skip-name-resolve Increasing wait_timeout Enabling bind-address I've run out of ideas now, and have no idea how to debug an odd issue like this. Has anyone come across this before, or have any idea how I could find the root of the issue, or what might be the problem?

• TCP dies on a Linux laptop

  - by Roman Cheplyaka

  Once in several days I have the following problem. My laptop (Debian GNU/Linux testing) suddenly becomes unable to work with TCP connections to the internet. The following things continue to work fine: UDP (DNS), ICMP (ping) — I get instant response TCP connections to other machines in the local network (e.g. I can ssh to a neighbour laptop) everything is ok for other machines in my LAN But when I try TCP connections from my laptop, they time out (no response to SYN packets). Here's a typical curl output: % curl -v google.com * About to connect() to google.com port 80 (#0) * Trying 173.194.39.105... * Connection timed out * Trying 173.194.39.110... * Connection timed out * Trying 173.194.39.97... * Connection timed out * Trying 173.194.39.102... * Timeout * Trying 173.194.39.98... * Timeout * Trying 173.194.39.96... * Timeout * Trying 173.194.39.103... * Timeout * Trying 173.194.39.99... * Timeout * Trying 173.194.39.101... * Timeout * Trying 173.194.39.104... * Timeout * Trying 173.194.39.100... * Timeout * Trying 2a00:1450:400d:803::1009... * Failed to connect to 2a00:1450:400d:803::1009: Network is unreachable * Success * couldn't connect to host * Closing connection #0 curl: (7) Failed to connect to 2a00:1450:400d:803::1009: Network is unreachable Restarting the connection and/or reloading the network card kernel module doesn't help. The only thing that helps is reboot. Clearly something is wrong with my system (everything else works fine), but I have no idea what exactly. I don't know how to reproduce this, but as I said, it happens every several days. My setup is a wireless router that is connected to the ISP via PPPoE. Any advice?

• High disk I/O activity in CentOS server

  - by triiim

  I have about 16 websites in a CentOS dedicated, and I am having some problems on high traffic hours, it seems to be a high disk I/O activity causing a general slowdown. I've installed atop and this is what I see on the bottom (the server has been restarted thats why the values are so low): *** system and process activity since boot *** PID RDDSK WRDSK WCANCL DSK CMD 1/18 2176 1.7G 7.3G 854.4M 39 mysqld 671 1248K 3.0G 0K 13 flush-8:0 566 0K 1.1G 0K 5 jbd2/sda2-8 2401 124.2M 529.1M 22408K 3 crond 2032 2.2G 502.0M 0K 12 nginx 2360 425.8M 115.3M 4188K 2 httpd flush-8:0 and jbd2/sda2-8 are the processes I see with iotop using 99% on the IO column, and they are the processes that write the most on the hdd (after mysql). From what I saw in google this could be caused by some ext4 related bug, the current kernel is: Linux srvr.com 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux I asked the hosting support to update the kernel and they tried but they now say that the server wont boot with the new installed kernel and they had to go back to the previous, they are not helping very much. Does someone has any idea how could I solve the high disk usage caused by flush-8:0 and jbd2/sda2-8 processes?

• grub refuses to install to raid array

  - by ronno

  I have a software raid 0 setup with dual booting Windows 7 and Ubuntu 12.04. The GRUB bootloader that is already on the hard drive seems to work fine. However, since the latest package update for grub, it refuses to install the new version to the hard disk. grub-install throws the following error: /usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/< raid name_RAID0p9. Check your device.map. Auto-detection of a filesystem of /dev/mapper/< raid name_RAID0p9 failed. Try with --recheck. If the problem persists please report this together with the output of "/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v /boot/grub" to < [email protected] update-grub pops the same "/usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/< raid name_RAID0p9. Check your device.map." every alternate line. I don't understand what exactly is going on. I'm afraid to reinstall the grub package because it might mess up the boot, which currently works fine. Is it safe to just ignore this?

• Dovecot starting and running, but not listening on any port

  - by Dženis Macanovic

  Among others things I'm in charge of a Debian GNU/Linux (Wheezy) DomU for the mail services of the company i work for. Yesterday one HDD that was used for this particular server has died. After installing Debian again, Dovecot decided to no longer listen on any ports (checked with netstat -l). Other services (like Postfix and MySQL) work without problems. dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-3-amd64 x86_64 Debian wheezy/sid ext3 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%n mail_uid = vmail namespace inbox { inbox = yes location = prefix = } pass db { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0666 user = vmail } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/ssl/private/mail.crt ssl_key = </etc/ssl/private/mail.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_max_userip_connections = 25 } UID 150 is vmail (I double checked file permissions). I didn't install Dovecot from source, but via apt from the official Debian US mirror. There are no messages concerning Dovecot in /var/log/syslog except for: Oct 21 06:36:29 server dovecot: master: Dovecot v2.1.7 starting up (core dumps disabled) Any ideas?

• HPET missing from available clocksources on CentOS

  I am having trouble using HPET on my physical machine. It is not available, even though I have enabled it in my bios, forced it in grub, and triple checked my kernel to include HPET in its compilation. Motherboard: Supermicro X9DRW Processor: 2x Intel(R) Xeon(R) CPU E5-2640 SAS Controller: LSI Logic / Symbios Logic SAS2004 PCI-Express Fusion-MPT SAS-2 [Spitfire] (rev 03) Distro: CentOS 6.3 Kernel: 3.4.21-rt32 #2 SMP PREEMPT RT x86_64 GNU/Linux Grub: hpet=force clocksource=hpet .config file: CONFIG_HPET_TIMER=y CONFIG_HPET_EMULATE_RTC=y CONFIG_HPET=y dmesg | grep hpet: Command line: ro root=/dev/mapper/vg_xxxx-lv_root rd_NO_LUKS rd_LVM_LV=vg_xxxx/lv_root KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_LVM_LV=vg_xxxx/lv_swap rd_NO_DM LANG=en_US.UTF-8 rhgb quiet panic=5 hpet=force clocksource=hpet Kernel command line: ro root=/dev/mapper/vg_xxxx-lv_root rd_NO_LUKS rd_LVM_LV=vg_xxxx/lv_root KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_LVM_LV=vg_xxxx/lv_swap rd_NO_DM LANG=en_US.UTF-8 rhgb quiet panic=5 hpet=force clocksource=hpet cat /sys/devices/system/clocksource/clocksource0/current_clocksource: tsc cat /sys/devices/system/clocksource/clocksource0/available_clocksource: tsc jiffies What is even more confusing, is that I have about a dozen other machines that utilize the same kernel .config, and can use HPET fine. I fear it is a hardware issue, but would appreciate any advice or help with getting HPET available. Thanks in advance!

• Mysterious swap usage on EC2

  - by rusty

  We're in the middle of a project to move our infrastructure from a co-lo situation into Amazon EC2 and we've noticed some weird memory characteristics of the processes in our setup. Without going into too much detail about the specifics of our processes, we've noticed that on our EC2 instances "top" will show processes using a lot of swap space -- in fact, much greater than the amount of available swap or (if you add it all up) more than the available disk. Here's a sample top output: Mem: 7136868k total, 5272300k used, 1864568k free, 256876k buffers Swap: 1048572k total, 0k used, 1048572k free, 2526504k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND 4121 jboss 20 0 5913m 603m 14m S 0.7 8.7 3:59.90 5.2g java 22730 root 20 0 2394m 4012 1976 S 2.0 0.1 4:20.57 2.3g PassengerHelper 20564 rails 20 0 2539m 220m 9828 S 0.3 3.2 0:23.58 2.3g java 1423 nscd 20 0 877m 1464 972 S 0.0 0.0 0:03.89 876m nscd You can see, for instance, that jboss is reportedly using 5.2 gigs of swap space which is definitely impossible since there's only 1G allocated and none is being used (probably because there's still 1.8G of RAM free). And here's the results of uname -a: Linux xxx.yyy.zzz 2.6.35.14-106.53.amzn1.x86_64 #1 SMP Fri Jan 6 16:20:10 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux We're running an AMI based off of the default Amazon Linux AMI (Amazon Linux AMI release 2011.09, so some RHEL5 and RHEL 6) with not too many customizations and definitely no kernel-level customizations. Something here tells me that on this particular kernel/distribution, the reporting of swap or maybe even total memory usage isn't what it appears to be... Any help would be appreciated!

• Static IP addressing issue in Ubuntu on BeagleBoneBlack Rev C

  - by Stringfellow

  I have my BBB configured to use a static IP address using the following in the file /etc/network/interfaces: allow-hotplug eth0 iface eth0 inet static address 192.168.0.1 netmask 255.255.255.0 network 192.168.0.0 This seems to work ok on boot, but when the ethernet cable is unplugged and then plugged back in, I lose the IP address. Any ideas what's going on here? Another weird symptom: If I boot the BBB with the network cable unplugged, but the switch it's plugged into off, I'll get my static IP. But, when I turn the switch on, I'll get a DHCP-assigned address. This is even though I have it configured with a static IP address. One last thing. If I ifdown etho, the interface will be gone when I do an ifconfig. If I wait a few seconds, though, and then re-run ifconfig, it will reappear, without an IP address. (Before I disabled IPv6, I used to get a IPv4 DHCP address in this case... weird). When that happens, I get a message like this in /var/log/messages: Apr 23 20:32:06 beaglebone kernel: [ 737.170172] libphy: 4a101000.mdio:00 - Link is Up - 100/Full Apr 23 20:32:06 beaglebone kernel: [ 737.170304] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready Here's my uname -a: root@beaglebone:/etc# uname -a Linux beaglebone 3.8.13-bone47 #1 SMP Fri Apr 11 01:36:09 UTC 2014 armv7l GNU/Linux Any ideas what's going on here?

• Truecrypt and hidden volumes

  - by user51166

  I would like to know the opinion of some users using (or not) the hidden volume encryption feature of Truecrypt. Personally until now I never used this feature: on Windows I encrypt the system drive as a standard volume, on GNU/Linux I encrypt using LUKS which is Truecrypt's equivalent to standard volume. As for data I use the standard volume approach as well. I read that this feature is nice and all, but it isn't really used by most people. Do you use it or not? Why? Do you only store inside it VERY sensible data or what else? Because technically speaking doing a hidden volume which has (almost) the same size as the outer one doesn't make sense: the outer volume will be encrypted but no data will be on it, which will appear very strange. So not only one has to plan which data store where, but has even to remember each time to mount the outer volume with hidden volume protection (otherwise there'll be a data loss when writing to it). It's a bit messy: hidden OS + outer OS + outer volume + hidden volume = 4 partitions :( Similar question about the hidden operating system (which I don't use [yet]).

• Boot stuck at blinking cursor before GRUB - only works via BIOS boot menu

  - by delta1

  I have a new box running Debian Squeeze. Grub is installed on /dev/sda, but when booting up I just get a blinking cursor, before the Grub menu. I can only boot to grub successfully when I choose boot options (during post) and select that specific drive! I have made sure the correct drive is set to boot first in the BIOS. So Grub works, but the system won't boot to that drive automatically? Any ideas on what could cause this? Drives sda/b/c are all 2TB (sda runs the system with b/c as raid device md0) with the following partitions: $ cat /proc/partitions major minor #blocks name 8 0 1953514584 sda 8 1 977 sda1 8 2 9765625 sda2 8 3 6445313 sda3 8 4 1937302627 sda4 8 32 1953514584 sdc 8 16 1953514584 sdb 9 0 1953513424 md0 but # fdisk -l /dev/sda gives WARNING: GPT (GUID Partition Table) detected on '/dev/sda'!

• mysqldump isn't able to export a specific database, phpMyAdmin crashes

  - by Devils Child

  I'm experiencing problems with a database on my server (Note: All other databases work fine). Once I try to export it with mysqldump I get this error: # mysqldump -u root -pXXXXXXXXX databasename > /root/databasename.sql mysqldump: Couldn't execute 'show table status like 'apps'': Lost connection to MySQL server during query (2013) Also, phpMyAdmin throws an error when selecting this database and immediately logs out. However, the web site which uses this database works fine. I can also execute SELECT statements on the table named "apps" from the MySQL shell. I tried restarting the MySQL daemon as well as REPAIR DATABASE and REPAIR TABLE but the problem still persists. I had this problem before, then it disappeared somehow without me doing anything to resolve the issue. Now, the problem is back and I'm simply unable to create a backup of this database.

• cpusets not working - threads aren't running in the cpuset I specified?

  I have used cpuset to shield some cpus for exclusive use by some realtime threads. Displaying the cpuset config with the test app RealtimeTest1 running and its tasks moved into the cpusets: $ cset set --list -r cset: Name CPUs-X MEMs-X Tasks Subs Path ------------ ---------- - ------- - ----- ---- ---------- root 0-23 y 0-1 y 279 2 / system 0,2,4,6,8,10 n 0 n 202 0 /system shield 1,3,5,7,9,11 n 1 n 0 2 /shield RealtimeTest1 1,3,5,7 n 1 n 0 4 /shield/RealtimeTest1 thread1 3 n 1 n 1 0 /shield/RealtimeTest1/thread1 thread2 5 n 1 n 1 0 /shield/RealtimeTest1/thread2 main 1 n 1 n 1 0 /shield/RealtimeTest1/main I can interrogate the cpuset filesystem to show that my tasks are supposedly pinned to the cpus I requested: /cpusets/shield/RealtimeTest1 $ for i in `find -name tasks`; do echo $i; cat $i; echo "------------"; done ./thread1/tasks 17651 ------------ ./main/tasks 17649 ------------ ./thread2/tasks 17654 ------------ Further, if I use sched_getaffinity, it reports what cpuset does - that thread1 is on cpu 3 and thread2 is on cpu 5. However, if I run top -p 17649 -H with f,j to bring up the last used cpu, it shows that thread 1 is running on thread 2's cpu, and main thread is running on a cpu in the system cpuset (Note that thread 17654 is running FIFO, hence thread 17651 is blocked) PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ P COMMAND 17654 root -2 0 54080 35m 7064 R 100 0.4 5:00.77 3 RealtimeTest 17649 root 20 0 54080 35m 7064 S 0 0.4 0:00.05 2 RealtimeTest 17651 root 20 0 54080 35m 7064 R 0 0.4 0:00.00 3 RealtimeTest Also, looking at /proc/17649/task to find the last_cpu each of its tasks ran on: /proc/17649/task $ for i in `ls -1`; do cat $i/stat | awk '{print $1 " is on " $(NF - 5)}'; done 17649 is on 2 17651 is on 3 17654 is on 3 So cpuset and sched_getaffinity reports one thing, but reality is another I would say that cpuset is not working? My machine configuration is: $ cat /etc/SuSE-release SUSE Linux Enterprise Server 11 (x86_64) VERSION = 11 PATCHLEVEL = 1 $ uname -a Linux foobar 2.6.32.12-0.7-default #1 SMP 2010-05-20 11:14:20 +0200 x86_64 x86_64 x86_64 GNU/Linux

• How to make a redundant desktop system with daily snapshots? (Is btrfs ready for use?)

  - by TestUser16418

  I want to configure a desktop system in which the home filesystem would be redundant (e.g. RAID-1), and would have weekly snapshots taken. I've already done this with ZFS, the snapshot system is wonderful, and with send/recv you can easily create backups on external media. Unfortunately, at that point, I want GNU+Linux and not FreeBSD or Solaris, so I'm looking for suggestions for good alternatives. I reckon that my alternatives are: btrfs - it seems to be exactly what I need, it has snapshots and commands that allow you to easily replicate zfs send. Yet all documentation mentions that it's still experimental. I can't seem to find any actual reports on its reliability or usability issues. Can you point me to any information on that issue that could clarify whether it would be a possible choice? I have a large preference for this option, mostly because I don't want to reformat the drives when btrfs becomes ready, but I there's no information on whether it's usable at all, whether it's a silly idea to use it, etc. The question that I cannot get the answer to is what does "experimental" mean. lvm snapshots and ext4 - preferably not, since it can consume an awful amount of space when new files are created. Creating 200 GB files requres 200 GB free space and 200 GB additionally for snapshots. I also have found it unreliable -- failed metadata rewrite results in an unreadable PV. I'm wondering how btrfs would compare here. A single filesystem (ext4) on a RAID-1 array with custom COW snapshots with hardlinks (like cp -al). That's my current preference if I can't use btrfs. So how experimental btrfs is, which should I choose, and do I have any other options? What if I don't keep external incremental backups, would that affect my choice?

• How do I re-configure grub options

  - by Ash

  I've searched this topic and I can't find an article with a plausable solution, to my problem. I installed windows 7 first, with 100gb of disk space. I created the necessary partitions via windows. Then I installed Ubuntu 12.04 on the remaining 400gb of disk space. During the Ubuntu installation I installed the ubuntu boot loader on /dev/sda3 which Windows (as expected never granted me the option pre-boot for which OS I wanted to boot). So I re-installed Ubuntu on that /dev/sda3 partition, overriding the windows 7 loader. Now when I boot windows 7, it runs GNU Grub, so like an infinite loop. How can I reconfigure grub to say: /dev/sda is the bootloader. /dev/sda2 is Windows. /dev/sda3 is Ubuntu. Re-installing windows and my partitions isn't an option, purchasing software for windows isn't an option (theres a reason I use linux, it's not because it's free, because you don't have to install lots of shit to get stuff working, and over-all it's a robust OS).

• Make eix available version match emerge

  - by Ryaner

  We have out Gentoo hosts using a binhost with EMERGE_DEFAULT_OPTS="--getbinpkgonly --usepkgonly" in the make.conf file so that the host only pulled down the binary hosts. All works well from that side. I use eix to check on software versions for upgrades but have hit a problem where eix will see an available version ahead of what is available on the binserver. Using glibc as an example ietpl [VE] / # emerge -s glibc Searching... [ Results for search key : glibc ] [ Applications found : 1 ] * sys-libs/glibc Latest version available: 2.14.1-r3 Latest version installed: 2.14.1-r3 Homepage: Description: GNU libc6 (also called glibc2) C library License: LGPL-2 Then eix reports a higher version available ietpl [VE] / # export LASTVERSION='{last}<version>{}' ietpl [VE] / # /usr/bin/eix --nocolor --format '<category> <name> [<installedversions:LASTVERSION>] [<bestversion:LASTVERSION>] \n' --exact --category-name sys-libs/glibc sys-libs glibc [2.14.1-r3] [2.15-r2] What I'm after is for eix to report the latest version available as 2.14.1-r3 like emerge. I've a feeling this is possible since without any formatting, eix returns Available versions: (2.2) ~2.9_p20081201-r3!s 2.10.1-r1!s 2.11.3!s ~2.12.1-r3!s 2.12.2!s{tbz2} ~2.13-r2!s 2.13-r4!s ~2.14!s ~2.14.1-r2!s 2.14.1-r3!s{tbz2} ~2.15-r1!s 2.15-r2!s ~2.15-r3!s **2.16.0!s **9999!s correctly tagging the latest unmasked binary package with {tbz2} I would have thought that the binary flag would do it, but that returns no matches --binary Match packages with *.tbz2 files.

• Programming activities for high school kids who have no idea what CS or programming is

  - by pointdxt

  I work at a small high school that's in a very high poverty area. There are only a handful of seniors that are thinking about applying to be an engineer of some sort in college and only 1 kid that applied for Computer Science (he has a couple acceptances so far!). He's been talking to me a lot as I majored in Computer Science as well and he is very excited about it. Unfortunately, our school doesn't have a Computer Science course of any kind so he asks me a lot of stuff. I want to help him out since he's really excited about majoring in CS but I don't know where to begin. I could say put Linux on a computer, go online and go research stuff like I did but this kid needs some direction and he doesn't even know what Linux is let alone have a free computer around for that sort of thing. He doesn't know much about CS but is keenly interested in having a computer do all sorts of things but I don't know how to help him in a meaningful way. Any advice? I'm not a teacher at the school so I'm not a great educator, I do IT at the school.

• Definition of the job titles involved in a software development process.

  - by Rafael Romão

  I have seen many job titles for people involved in a software development process, but never found a consensus about they mean. I know many of them are equivalent, and found some other questions about that here in SO, but I would like to know your definitions and comments about them. I want not only to know if there is really a consensus, but also to know if what I suppose to be a Software Architect, is really a Software Architect, and so on. The job titles I mean are: Developer; System Analyst; Programmer; Analyst Programmer; Software Engineer; Software Architect; Designer; Software Designer; Business Manager; Business Analyst; Program Manager; Project Manager; Development Manager; Tester; Support Analyst; Please, feel free to add more titles to this list in your answers. It would be very helpful.

• mono --aot with MinGW: unknown pseudo-op: `.local'

  - by Jared Updike

  Can I user mono's AOT feature to natively "pre-compile" .NET DLLs (and or EXEs) to make them harder to reverse engineer? If so, how do I get mono/AOT working in Windows 7? (I'm running x64 but the app is targeting x86 explicitly.) I just installed Mono 2.6.3 and MinGW 5.1.6 and I'm trying to AOT compile an exe (or a dll, it doesn't matter). I get screens and screens of error messages: C:\Users\jupdike\AppData\Local\Temp\mono_aot_XSDEAV:533: Error: junk at end of line, first unrecognized character is `H' C:\Users\jupdike\AppData\Local\Temp\mono_aot_XSDEAV:539: Error: unknown pseudo-op: `.local' C:\Users\jupdike\AppData\Local\Temp\mono_aot_XSDEAV:546: Warning: .size pseudo-op used outside of .def/.endef ignored.

• Grails - Simple hasMany Problem - How does 'save' work?

  - by gav

  My problem is this: I want to create a grails domain instance, defining the 'Many' instances of another domain that it has. I have the actual source in a Google Code Project but the following should illustrate the problem. class Person { String name static hasMany[skills:Skill] static constraints = { id (visible:false) skills (nullable:false, blank:false) } } class Skill { String name String description static constraints = { id (visible:false) name (nullable:false, blank:false) description (nullable:false, blank:false) } } If you use this model and def scaffold for the two Controllers then you end up with a form like this that doesn't work; My own attempt to get this to work enumerates the Skills as checkboxes and looks like this; But when I save the Volunteer the skills are null! This is the code for my save method; def save = { log.info "Saving: " + params.toString() def skills = params.skills log.info "Skills: " + skills def volunteerInstance = new Volunteer(params) log.info volunteerInstance if (volunteerInstance.save(flush: true)) { flash.message = "${message(code: 'default.created.message', args: [message(code: 'volunteer.label', default: 'Volunteer'), volunteerInstance.id])}" redirect(action: "show", id: volunteerInstance.id) log.info volunteerInstance } else { render(view: "create", model: [volunteerInstance: volunteerInstance]) } } This is my log output (I have custom toString() methods); 2010-05-10 21:06:41,494 [http-8080-3] INFO bumbumtrain.VolunteerController - Saving: ["skills":["1", "2"], "name":"Ian", "_skills":["", ""], "create":"Create", "action":"save", "controller":"volunteer"] 2010-05-10 21:06:41,495 [http-8080-3] INFO bumbumtrain.VolunteerController - Skills: [1, 2] 2010-05-10 21:06:41,508 [http-8080-3] INFO bumbumtrain.VolunteerController - Volunteer[ id: null | Name: Ian | Skills [Skill[ id: 1 | Name: Carpenter ] , Skill[ id: 2 | Name: Sound Engineer ] ]] Note that in the final log line the right Skills have been picked up and are part of the object instance. When the volunteer is saved the 'Skills' are ignored and not commited to the database despite the in memory version created clearly does have the items. Is it not possible to pass the Skills at construction time? There must be a way round this? I need a single form to allow a person to register but I want to normalise the data so that I can add more skills at a later time. If you think this should 'just work' then a link to a working example would be great. Hope this makes sense, thanks in advance! Gav

• Using regex to extract variables from a plain-text form letter?

  - by Yaaqov

  Hi - I'm looking for a good example of using Regular Expressions in PHP to "reverse engineer" a form letter (with a known format, of course) that has been pasted into a multiline textbox and sent to a script for processing. So, for example, let's assume this is the original plain-text input (taken from a USDA press release): WASHINGTON, April 5, 2010 - North American Bison Co-Op, a New Rockford, N.D., establishment is recalling approximately 25,000 pounds of whole beef heads containing tongues that may not have had the tonsils completely removed, which is not compliant with regulations that require the removal of tonsils from cattle of all ages, the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) announced today. For clarity, the fields that are variables are highlighted below: [pr_city=]WASHINGTON, [pr_date=]April 5, 2010 - [corp_name=]North American Bison Co-Op, a [corp_city=]New Rockford, [corp_state=]N.D., establishment is recalling approximately [amount=]25,000 pounds of [product=]whole beef heads containing tongues that may not have had the tonsils completely removed, which is not compliant with regulations that require [reason=]the removal of tonsils from cattle of all ages, the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) announced today. How could I efficiently extract the contents of the pr_city pr_date corp_name corp_city corp_state amount product reason fields from my example? Any help would be appreciated, thanks.
