• Setting up two screens in Xorg

  - by viraptor

  I'be got two Nvidia cards, but Xorg activates only one of them. The following config is based on the nvidia configurator output: Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" LeftOf "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Module" Load "dbe" Load "extmod" Load "type1" Load "freetype" Load "glx" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "keyboard" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "HP LE2201w" HorizSync 24.0 - 83.0 VertRefresh 50.0 - 76.0 Option "DPMS" EndSection Section "Monitor" Identifier "Monitor1" VendorName "Unknown" ModelName "Acer AL2017" HorizSync 30.0 - 82.0 VertRefresh 56.0 - 76.0 Option "DPMS" EndSection Section "Device" Identifier "Card0" Driver "nvidia" VendorName "nVidia Corporation" BoardName "GeForce 6100 nForce 405" BusID "PCI:0:13:0" EndSection Section "Device" Identifier "Card1" Driver "nvidia" VendorName "nVidia Corporation" BoardName "GeForce 8400 GS" BusID "PCI:2:0:0" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection What I see in the log file is: (==) Log file: "/var/log/Xorg.0.log", Time: Fri Mar 19 11:08:08 2010 (==) Using config file: "/etc/X11/xorg.conf" (==) ServerLayout "Layout0" (**) |-->Screen "Screen0" (0) (**) | |-->Monitor "Monitor0" (==) No device specified for screen "Screen0".

• Configuring varnish and django (apache/modwsgi)

• Why does NX Client for Windows silently closes after connection?

  - by pavel

  Hey! I connect remotely to my Ubuntu server from Vista machine. Now I need to run a GUI application on the server (Wireshark). So I decided to use FreeNX server/client to view Ubuntu GUI on Vista I have successfully installed FreeNX on Ubuntu and NX Client on Vista. I was following this guide Unfortunately, now I found myself stuck with the following problem. At the client, the !M logo window appears, but after a few seconds that window just closes, even without showing any error message. Guys, I'm really stuck, please help! Maybe I should have installed some graphical environment on the server? These are the details from NX client, it seems there are no errors. ----------------- Info: Display running with pid '7768' and handler '0x670d24'.

• Command-line connect to wired network for Ubuntu

  I like to know how to use command-line to connect to a wired network in general for Ubuntu 8.10? In my case, I connect a cable to my laptop but it doesn't work with my WICD.

• Stop duplicate icmp echo replies when bridging to a dummy interface?

  - by mbrownnyc

  I recently configured a bridge br0 with members as eth0 (real if) and dummy0 (dummy.ko if). When I ping this machine, I receive duplicate replies as: # ping SERVERA PING SERVERA.domain.local (192.168.100.115) 56(84) bytes of data. 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=1 ttl=62 time=113 ms 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=1 ttl=62 time=114 ms (DUP!) 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=2 ttl=62 time=113 ms 64 bytes from SERVERA.domain.local (192.168.100.115): icmp_seq=2 ttl=62 time=113 ms (DUP!) Using tcpdump on SERVERA, I was able to see icmp echo replies being sent from eth0 and br0 itself as follows (oddly two echo request packets arrive "from" my Windows box myhost): 23:19:05.324192 IP myhost.domain.local > SERVERA.domain.local: ICMP echo request, id 512, seq 43781, length 40 23:19:05.324212 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324217 IP myhost.domain.local > SERVERA.domain.local: ICMP echo request, id 512, seq 43781, length 40 23:19:05.324221 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324264 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 23:19:05.324272 IP SERVERA.domain.local > myhost.domain.local: ICMP echo reply, id 512, seq 43781, length 40 It's worth noting, testing reveals that hosts on the same physical switch do not see DUP icmp echo responses (a host on the same VLAN on another switch does see a dup icmp echo response). I've read that this could be due to the ARP table of a switch, but I can't find any info directly related to bridges, just bonds. I have a feeling my problem lay in the stack on linux, not the switch, but am opened to any suggestions. The system is running centos6/el6 kernel 2.6.32-71.29.1.el6.i686. How do I stop ICMP echo replies from being sent in duplicate when dealing with a bridge interface/bridged interfaces? Thanks, Matt [edit] Quick note: It was recommended in #linux to: [08:53] == mbrownnyc [gateway/web/freenode/] has joined ##linux [08:57] <lkeijser> mbrownnyc: what happens if you set arp_ignore to 1 for the dummy interface? [08:59] <lkeijser> also set arp_announce to 2 for that interface [09:24] <mbrownnyc> lkeijser: I set arp_annouce to 2, arp_ignore to 2 in /etc/sysctl.conf and rebooted the machine... verifying that the bits are set after boot... the problem is still present I did this and came up empty. Same dup problem. I will be moving away from including the dummy interface in the bridge as: [09:31] == mbrownnyc [gateway/web/freenode/] has joined #Netfilter [09:31] <mbrownnyc> Hello all... I'm wondering, is it correct that even with an interface in PROMISC that the kernel will drop /some/ packets before they reach applications? [09:31] <whaffle> What would you make think so? [09:32] <mbrownnyc> I ask because I am receiving ICMP echo replies after configuring a bridge with a dummy interface in order for ipt_netflow to see all packets, only as reported in it's documentation: http://ipt-netflow.git.sourceforge.net/git/gitweb.cgi?p=ipt-netflow/ipt-netflow;a=blob;f=README.promisc [09:32] <mbrownnyc> but I do not know if PROMISC will do the same job [09:33] <mbrownnyc> I was referred here from #linux. any assistance is appreciated [09:33] <whaffle> The following conditions need to be met: PROMISC is enabled (bridges and applications like tcpdump will do this automatically, otherwise they won't function). [09:34] <whaffle> If an interface is part of a bridge, then all packets that enter the bridge should already be visible in the raw table. [09:35] <mbrownnyc> thanks whaffle PROMISC must be set manually for ipt_netflow to function, but [09:36] <whaffle> promisc does not need to be set manually, because the bridge will do it for you. [09:36] <whaffle> When you do not have a bridge, you can easily create one, thereby rendering any kernel patches moot. [09:36] <mbrownnyc> whaffle: I speak without the bridge [09:36] <whaffle> It is perfectly valid to have a "half-bridge" with only a single interface in it. [09:36] <mbrownnyc> whaffle: I am unfamiliar with the raw table, does this mean that PROMISC allows the raw table to be populated with packets the same as if the interface was part of a bridge? [09:37] <whaffle> Promisc mode will cause packets with {a dst MAC address that does not equal the interface's MAC address} to be delivered from the NIC into the kernel nevertheless. [09:37] <mbrownnyc> whaffle: I suppose I mean to clearly ask: what benefit would creating a bridge have over setting an interface PROMISC? [09:38] <mbrownnyc> whaffle: from your last answer I feel that the answer to my question is "none," is this correct? [09:39] <whaffle> Furthermore, the linux kernel itself has a check for {packets with a non-local MAC address}, so that packets that will not enter a bridge will be discarded as well, even in the face of PROMISC. [09:46] <mbrownnyc> whaffle: so, this last bit of information is quite clearly why I would need and want a bridge in my situation [09:46] <mbrownnyc> okay, the ICMP echo reply duplicate issue is likely out of the realm of this channel, but I sincerely appreciate the info on the kernels inner-workings [09:52] <whaffle> mbrownnyc: either the kernel patch, or a bridge with an interface. Since the latter is quicker, yes [09:54] <mbrownnyc> thanks whaffle [edit2] After removing the bridge, and removing the dummy kernel module, I only had a single interface chilling out, lonely. I still received duplicate icmp echo replies... in fact I received a random amount: http://pastebin.com/2LNs0GM8 The same thing doesn't happen on a few other hosts on the same switch, so it has to do with the linux box itself. I'll likely end up rebuilding it next week. Then... you know... this same thing will occur again. [edit3] Guess what? I rebuilt the box, and I'm still receiving duplicate ICMP echo replies. Must be the network infrastructure, although the ARP tables do not contain multiple entries. [edit4] How ridiculous. The machine was a network probe, so I was (ingress and egress) mirroring an uplink port to a node that was the NIC. So, the flow (must have) gone like this: ICMP echo request comes in through the mirrored uplink port. (the real) ICMP echo request is received by the NIC (the mirrored) ICMP echo request is received by the NIC ICMP echo reply is sent for both. I'm ashamed of myself, but now I know. It was suggested on #networking to either isolate the mirrored traffic to an interface that does not have IP enabled, or tag the mirrored packets with dot1q.

• Reasons for missing IP info in `last` output on pts logins?

  I have five CentOS 6 linux systems at work, and encountered a rather strange issue that only seems to happen with my userid across all the linux systems I have...

My CentOS machines have as many as six other users that share the systems, but the mpenning userid is the only one that has this issue. Approximately 5% of my logins see this issue, but no other usernames exhibit this behavior. Questions Given the kind of scripts I keep on these systems (which control much of our network infrastructure), I'm a little spooked by this and would like to understand what would cause my logins to occasionally miss source addresses. Is there anything (other than malicious activity) that would reasonably explain the behavior? Other than bash history timestamping, are there other things I can do to track the issue down? Informational Since this started happening, I enabled bash history time-stamping (i.e. HISTTIMEFORMAT="%y-%m-%d %T " in .bash_profile) and also added a few other bash history hacks; however, that does not give clues to what happened during the previous occurrences. All the systems run CentOS 6.3...

• Finding the reason of a force shutdown of a VM

  - by Ricardo Reyes

  We have a linux VM running under XenServer that reboots itself with no apparent reason. Checking the /var/log files in Xen we noticed that it's sending a force shutdown to the VM, like this: messages:Dec 6 15:01:07 XenSrvDell2 BLKTAP-DAEMON[7309]: /local/domain/0/backend/tap/19/51728: got start/shutdown watch on /local/domain/0/backend/tap/19/51728/tapdisk-request What we can't find is the reason why the force-shutdown was initiated. Is there any "higher level log" that might tell us who or why triggered the shutdown?

• .htaccess ignored, SPECIFIC to EC2 - not the usual suspects

  - by tedneigerux

  I run 8-10 EC2 based web servers, so my experience is many hours, but is limited to CentOS; specifically Amazon's distribution. I'm installing Apache using yum, so therefore getting Amazon's default compilation of Apache. I want to implement canonical redirects from non-www (bare/root) domain to www.domain.com for SEO using mod_rewrite BUT MY .htaccess FILE IS CONSISTENTLY IGNORED. My troubleshooting steps (outlined below) lead me to believe it's something specific to Amazon's build of Apache. TEST CASE Launch a EC2 Instance, e.g. Amazon Linux AMI 2013.03.1 SSH to the Server Run the commands: $ sudo yum install httpd $ sudo apachectl start $ sudo vi /etc/httpd/conf/httpd.conf $ sudo apachectl restart $ sudo vi /var/www/html/.htaccess In httpd.conf I changed the following, in the DOCROOT section / scope: AllowOverride All In .htaccess, added: (EDIT, I added RewriteEngine On later) RewriteCond %{HTTP_HOST} ^domain\.com$ [NC] RewriteRule ^/(.*) http://www.domain.com/$1 [R=301,L] Permissions on .htaccess are correct, AFAI can tell: $ ls -al /var/www/html/.htaccess -rwxrwxr-x 1 git apache 142 Jun 18 22:58 /var/www/html/.htaccess Other info: $ httpd -v Server version: Apache/2.2.24 (Unix) Server built: May 20 2013 21:12:45 $ httpd -M Loaded Modules: core_module (static) ... rewrite_module (shared) ... version_module (shared) Syntax OK EXPECTED BEHAVIOR $ curl -I domain.com HTTP/1.1 301 Moved Permanently Date: Wed, 19 Jun 2013 12:36:22 GMT Server: Apache/2.2.24 (Amazon) Location: http://www.domain.com/ Connection: close Content-Type: text/html; charset=UTF-8 ACTUAL BEHAVIOR $ curl -I domain.com HTTP/1.1 200 OK Date: Wed, 19 Jun 2013 12:34:10 GMT Server: Apache/2.2.24 (Amazon) Connection: close Content-Type: text/html; charset=UTF-8 TROUBLESHOOTING STEPS In .htaccess, added: BLAH BLAH BLAH ERROR RewriteCond %{HTTP_HOST} ^domain\.com$ [NC] RewriteRule ^/(.*) http://www.domain.com/$1 [R=301,L] My server threw an error 500, so I knew the .htaccess file was processed. As expected, it created an Error log entry: [Wed Jun 19 02:24:19 2013] [alert] [client XXX.XXX.XXX.XXX] /var/www/html/.htaccess: Invalid command 'BLAH BLAH BLAH ERROR', perhaps misspelled or defined by a module not included in the server configuration Since I have root access on the server, I then tried moving my rewrite rule directly to the httpd.conf file. THIS WORKED. This tells us several important things are working. $ curl -I domain.com HTTP/1.1 301 Moved Permanently Date: Wed, 19 Jun 2013 12:36:22 GMT Server: Apache/2.2.24 (Amazon) Location: http://www.domain.com/ Connection: close Content-Type: text/html; charset=UTF-8 HOWEVER, it is bothering me that it didn't work in the .htaccess file. And I have other use cases where I need it to work in .htaccess (e.g. an EC2 instance with named virtual hosts). Thank you in advance for your help.

• How to version lock packages in Ubuntu?

  - by Sandra

  On CentOS exists the yum versionlock option, where you can lock a package to a specific version, so it is never upgraded past that. I would like that puppet-server-2.7.19-1 puppet-2.7.19-1 stays on 2.7, and never upgraded to 3.0. Puppet Labs have released 3.0 and put it into the stable repo, so 2.7 will get upgraded to 3.0, which is not backwards compatible. Does Ubuntu have something similar to yum versionlock?

• Windows using the DNS suffix search list on all lookups, even valid FQDNs. How to stop this?

  - by RealityGone

  When doing DNS lookups (specifically using nslookup, for some reason most things are not effected) Windows XP Pro SP3 is using the DNS suffix search list for every single one. Even for fully qualified domain names. For example I lookup "www.microsoft.com" but windows actually asks for "www.microsoft.com.eondream.com" (eondream.com is my primary domain). Now I can fix the issue by removing the Primary DNS suffix, but it seems to me that the DNS suffix search list should be for short, invalid names (where dots=0 or something). I'm sure I have a misconfiguration somewhere in windows but I don't know where. I've changed every option I can think of or find. Below is the output of ipconfig /all and nslookup (with debug & db2 enabled). This is using a static IP & (internal) DNS server. C:\ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : frayedlogic Primary Dns Suffix . . . . . . . : eondream.com Node Type . . . . . . . . . . . . : Unknown IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : eondream.com Ethernet adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Dell Wireless 1390 WLAN Mini-Card Physical Address. . . . . . . . . : 00-1B-FC-29-EB-6B Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.13.32 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.13.13 DNS Servers . . . . . . . . . . . : 192.168.19.19 C:\nslookup Default Server: shardik.eondream.com Address: 192.168.19.19 set debug set db2 www.microsoft.com Server: shardik.eondream.com Address: 192.168.19.19 ------------ Got answer: HEADER: opcode = QUERY, id = 2, rcode = NOERROR header flags: response, want recursion, recursion avail. questions = 1, answers = 1, authority records = 0, additional = 0 QUESTIONS: www.microsoft.com.eondream.com, type = A, class = IN ANSWERS: - www.microsoft.com.eondream.com internet address = 208.69.36.132 ttl = 0 (0 secs) ------------ Non-authoritative answer: Name: www.microsoft.com.eondream.com Address: 208.69.36.132 (Note: it resolves to that IP because I use the opendns service and that is their suggestion page or whatever you want to call it) If I am reading the nslookup output correctly then it is not a problem with my DNS server because windows is actually asking for the incorrect domain.

• XML Serialization is not including milliseconds in datetime field from Rails model

  - by revgum

  By default, the datetime field from the database is being converted and stripping off the milliseconds: some_datetime = "2009-11-11T02:19:36Z" attribute_before_type_cast('some_datetime') = "2009-11-11 02:19:36.145" If I try to overrride the accessor for this attribute like; def some_datetime attribute_before_type_cast('some_datetime') end when I try "to_xml" for that model, I get the following error: NoMethodError (undefined method `xmlschema' for "2009-11-11 02:19:36.145":String): I have tried to parse the String to a Time object but can't get one to include the milliseconds; def some_datetime Time.parse(attribute_before_type_cast('some_datetime').sub(/\s/,"T").sub(/$/,"Z")) end Can anyone help get get a datetime with milliseconds rendered by to_xml?

• Does RVM "failover" to another ruby instance on error?

  - by JohnMetta

  Have a strange problem in that I have a Rake task that seems to be using multiple versions of Ruby. When one fails, it seems to try another one. Details MacBook running 10.6.5 rvm 1.1.0 Rubies: 1.8.7-p302, ree-1.8.7-2010.02, ruby-1.9.2-p0 Rake 0.8.7 Gem 1.3.7 Veewee (provisioning Virtual Machines using Opcode.com, Vagrant and Chef) I'm not entirely sure the specific details of the error matter, but since it might be an issue with Veewee itself. So, what I'm trying to do is build a new box base on a veewee definition. The command fails with an error about a missing method- but what's interesting is how it fails. Errors I managed to figure out that if I only have one Ruby installed with RVM, it just fails. If I have more than one Ruby install, it fails at the same place, but execution seems to continue in another interpreter. Here are two different clipped console outputs. I've clipped them for size. The full outputs of each error are available as a gist. One Ruby version installed Here is the command run when I only have a single version of Ruby (1.8.7) available in RVM boudica:veewee john$ rvm rake build['mettabox'] --trace rvm 1.1.0 by Wayne E.

Prior to doing this, I used "rvm use 1.8.7." Again, I don't know how important the details of the specific errors are- what's interesting to me is that there are three separate errors- each with it's own stacktrace- and each in a different Ruby interpreter.

• Date Picker Blue

  - by Matt Winters

  I'm successfully setting a date-picker with an initial date from a plist, but I see some unwanted blue values in the month, day, and year components, presumably corresponding to current date. So if today is April 18, 2010 and initial date being set is March 19, 2008, it looks like this (bold represents the blue): January 17 2006 February 18 2007 ------------------------------ March 19 2008 ------------------------------ April 20 2009 May 21 2010 First question is: How do I get rid of the blue? And second question: Ideally, how do I get it to look like this? January 17 2006 February 18 2007 ------------------------------ March 19 2008 ------------------------------ April 20 2009 May 21 2010 Third question, totally unrelated and not as important: How could I have gotten the above to show in blue rather than bold? I see blue in code snippets all the time. Matt

• reading a string with spaces with sscanf

  - by SDLFunTimes

  For a project I'm trying to read an int and a string from a string. The only problem is sscanf appears to break reading an %s when it sees a space. Is there anyway to get around this limitation? Here's an example of what I'm trying to do: #include<stdio.h> #include<stdlib.h> int main(int argc, char** argv) { int age; char* buffer; buffer = malloc(200 * sizeof(char)); sscanf("19 cool kid", "%d %s", &age, buffer); printf("%s is %d years old\n", buffer, age); return 0; } What it prints is: "cool is 19 years old" where I need "cool kid is 19 years old". Does anyone know how to fix this?

• Reading Stacktrace in Objective-C?

  - by yar

  I don't like real-time debugging much, but if it's necessary I'll do it. Is there any way to figure out what line of code a StackTrace in Objective-C refers to? What about the variable it refers to? For instance: 2010-05-13 19:39:11.673 Thingers[21003:207] *** -[NSCFString count]: unrecognized selector sent to instance 0x3b0ebb0 2010-05-13 19:39:11.674 Thingers[21003:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFString count]: unrecognized selector sent to instance 0x3b0ebb0' 2010-05-13 19:39:11.675 Thingers[21003:207] Stack: ( 29303899 ... 11130 ) I see that we're talking about sending a count message to something that doesn't have it (maybe it's a NSCFString?), but is there any way to figure out what a/the named reference to that instance (0x3b0ebb0) refers to?

  I have a regex used to validate dates: ^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$ Works really well, but I am using it all over the place with asp.net regex validators and I want to minimize it so I can reduce page size. It works with dd/mm/yyyy format and handles leap years. I'm looking for a more concise regex statement.

• How can I replace only the last occurence of an number in a string with php?

  - by Shawn

  How would you change this: a-10-b-19-c into something like this: a-10-b-20-c using regular expressions in PHP? The only solution I've found so far is: reverse the original string - "c-91-b-01-a" find the first number - "91" reverse it - "19" turn in into a number (parseInt) - 19 add 1 to it (+1) - 20 turn it into a string again (toString) - "20" reverse it again - "02" replace the original match with this new number - "c-02-b-01-a" reverse the string - "a-10-b-20-c" I was hoping someone on SO would have a simpler way to do this... Anyone?

• Why would the first call to a KVC setter have an NSTextField instance as the argument?

  - by Stephen

  If I have a NSTextField bound through an NSObjectController to a model object, I would expect the setter of the model object to be called with an NSString as the argument, but instead, I receive the instance of the control that I am bound too the first time I am called. - (NSString *)property { NSLog(@"returning property"); return property; } - (void)setProperty:(NSString *)string { NSLog(@"recieved %@", string) } - (id) init { if (self = [super init]) { property = [[NSString alloc] initWithString:@"value"]; } NSLog(@"property is %@",property"); return self; } (The program doesn't run if you try anything in setProperty, because it tries to send NSString messages to string - which might be an NSTextField.) Console Output: 2010-05-12 14:19:14.096 Trouble[13108:10b] property is enter value 2010-05-12 14:19:14.100 Trouble[13108:10b] recieved <NSTextField: 0x1025210> 2010-05-12 14:19:14.106 Trouble[13108:10b] returning property

• ADT will not allow creation of Android Activity

  - by NewShelbyWoo

  I installed the ADT bundle from http://developer.android.com/sdk/index.html yesterday, and I was following a basic Hello World tutorial. I created a new Android Application Project with a Blank Activity named MainActivity. The resulting project has an empty src folder and empty res\layout folder. There is a R.java file in the gen folder but it has no reference to MainActivity. This is what the SDK manager says I have installed Android SDK Tools v 22.6 Android SDK Platform-tools v 19.0.1 Android SDK Build-tools v 19 SDK Platform v 3 ARM EABI v7a System Image v 2 Android Support Library v 19.0.1 Google USB Driver v 9 I also tried manually creating an activity by right clicking the src folder and going to Android Activity, but when I hit Finish on the creation wizard, nothing happens. Does anyone have any clues as to what's going on? Did I miss a key component to install or something?

• how to combine these queries

  - by mmcgrail

  and get meaningful results. Currently I am running these three queries: SELECT t.type,t.id,s.title FROM db1.tags t INNER JOIN db1.st s ON s.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='s' ORDER BY tag desc LIMIT 0, 19 SELECT t.type,t.id,v.title FROM db1.tags t INNER JOIN db1.vi v ON v.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='v' ORDER BY tag desc LIMIT 0, 19 SELECT t.type,t.id,i.ca AS title FROM db1.tags t INNER JOIN db2.tablename i ON i.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='i' ORDER BY tag desc LIMIT 0, 19 then trying to combine the data results but what I would really prefer is if I could combine them into a single query. Any thoughts?

• PHP Array Efficiency and Memory Clarification

  - by CogitoErgoSum

  When declaring an Array in PHP, the index's may be created out of order...I.e Array[1] = 1 Array[19] = 2 Array[4] = 3 My question. In creating an array like this, is the length 19 with nulls in between? If I attempted to get Array[3] would it come as undefined or throw an error? Also, how does this affect memory. Would the memory of 3 index's be taken up or 19? Also currently a developer wrote a script with 3 arrays FailedUpdates[] FailedDeletes[] FailedInserts[] Is it more efficient to do it this way, or do it in the case of an associative array controlling several sub arrays "Failures" array(){ ["Updates"] => array(){ [0] => 12 [1] => 41 } ["Deletes"] => array(){ [0] => 122 [1] => 414 [1] => 43 } ["Inserts"] => array(){ [0] => 12 } }
