• Economical DNS hosting separate from local registrar for country specific TLDs - email or web hosting not required

  - by Eric Nguyen

  Our company owns many country specific top level domains (TLDs; .sg, .my). We will purchase more for other countries in all South East Asia. These domains are associated with our websites hosted on Amazon EC2. The DNS records are currently hosted on a dedicated server that will shut down tomorrow. (The name servers are set to the ones of a web hosting company) Therefore, I will need to host the DNS records somewhere else. Hosting the DNS records with the local registrar costs SGD18 a year per domain in addition to the domain price (which is already very expensive but we have no choice). It would be convenience to host DNS recors for all the country specific TLDs we have using a single service, separate from the local registrars from which we bought the domains. A few searches prompted examples like Amazon Route 53 and dnsmadeeasy.com and the likes. However, since I'm only concern about the country specific TLDs, not .com 1) Is it really economical to host DNS records of all domains in 1 single place as described above? (Have the relevant countries and/or the local registrars done something to keep their monopoly and always charges ridiculous prices for their country specific TLDs?) 2) I would imagine I will need to tell the local registrars to update the name servers to those of the DNS hosting service provider e.g. dnsmadeeasy.com here. Am I correct about how it works here? 3) Will I be able point the TLDs themselves to IP addresses I desire (the EC2 instances where my websites are) or will I only able to do so with the subdomains? 4) Are there any drawbacks that I should know here? Background about our needs: We need the websites associated with the country TLDs to be up and running all the times Also, we'll need to be able to add/edit A and CNAME records We use Google Apps for Business for internal email so I will need to be able to add/edit MX records and TXT records

• Setting up home DNS with Ubuntu Server

  - by Zeophlite

  I have a webserver (with static IP 192.168.1.5), and I want to have my machines on my local network to be able to access it without modifying /etc/hosts (or equivalent for Windows/OSX). My router has Primary DNS server 192.168.1.5 Secondary DNS server 8.8.8.8 (Google's public DNS). Nginx is set up to server websites externally as *.example.com Internally, I want *.example.local to point to the server. My webserver has BIND9 installed, but I'm unsure of the settings. I've been through various contradicting tutorials, and so most of my settings have been clobbered. I've stripped out the lines which I'm confused about. The tutorials I looked at are http://tech.surveypoint.com/blog/installing-a-local-dns-server-behind-a-hardware-router/ and http://ubuntuforums.org/showthread.php?t=236093 . They mostly differ on what should be put in /etc/bind/zones/db.example.local and /etc/bind/zones/db.192, so I've left the conflicting lines out below. Can someone suggest what the correct lines are to give my above behaviour (namely *.example.local pointing to 192.168.1.5)? /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.5 netmask 255.255.255.0 broadcast 192.168.1.255 gateway 192.168.1.254 /etc/hostname avalon /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN /etc/bind/named.conf.options options { directory "/var/cache/bind"; forwarders { 8.8.8.8; 8.8.4.4; }; dnssec-validation auto; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; /etc/bind/named.conf.local zone "example.local" { type master; file "/etc/bind/zones/db.example.local"; }; zone "1.168.192.in-addr.arpa" { type master; file "/etc/bind/zones/db.192"; }; /etc/bind/zones/db.example.local $TTL 604800 @ IN SOA avalon.example.local. webadmin.example.local.

( 4 ; Serial, increment each edit 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL ; What do I need to add to the above files so that on a laptop on the internal network, I can type in webapp.example.local, and be served by my webserver? EDIT I made several changes to the above files on the webserver. /etc/network/interfaces (end of file) dns-nameservers 127.0.0.1 dns-search example.local /etc/bind/zones/db.example.local (end of file) @ IN NS avalon.example.local. @ IN A 192.168.1.5 avalon IN A 192.168.1.5 webapp IN A 192.168.1.5 www IN CNAME 192.168.1.5 /etc/bind/zones/db.192 (end of file) IN NS avalon.example.local. 73 IN PTR avalon.example.local. As a side note, my spare Win7 machine was able to connect directly to webapp.example.local, but for a Ubuntu 13.10 machine, I had to make the following changes as well (not on the webserver, but on a separate machine): /etc/nsswitch.conf before hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 after hosts: files dns /etc/NetworkManager/NetworkManager.conf before dns=dnsmasq after #dns=dnsmasq The issue remains that its not wildcard DNS, and so I have to add entries to /etc/bind/zones/db.example.local for webapp1, webapp2, ...

• Can I show a table of one custom variable against another?

  - by Simon

  We have a number of custom variables set up in google analytics. We'd like to show a table of event occurrences broken down by two custom variables, e.g. if variable one can be A, B, or C and variable two can be J, K or L: Events | A | B | C | -------+-----+-----+-----+ J | 345 | 65 | 12 | K | 234 | 43 | 7 | L | 123 | 21 | 4 | -------+-----+-----+-----+ How do I get the information in that format?

• Rewrite img and link paths with htaccess and serve the file from rewritten path?

  - by frequent

  I have a static mockup page, which I want to "customize" by switching a variable used in image-src and link-href attributes. Paths will look like this: <img src="/some/where/VARIABLE/img/1.jpg" alt="" /> <link rel="some" href="/some/where/VARIABLE/stuff/foo.bar" /> I'm setting a cookie with the VARIABLE value on the preceding page and now want to modfiy the paths accordingly by replacing VARIABLE with the cookie value. I'm a htaccess newbie. This is what I have (doesn't work): <IfModule mod_rewrite.c> # get cookie value cookie RewriteCond %{HTTP_COOKIE} client=([^;]*) # rewrite/redirect to correct file RewriteRule ^/VARIABLE/(.+)$ /%1/$1 [L] </IfModule> So I thought my first line gets the cookie value and stores this in %1. And on the second line I'm filtering VARIABLE, replace it with the cookie value and whatever comes after VARIABLE in $1. Thanks for sheeding some light on what I'm doing, doing wrong and if I can do this at all using htaccess. EDIT: I'm sort of halfway through, but it's still not working... Mabye someone can apply the finishing touches: <IfModule mod_rewrite.c> # check for client cookie RewriteCond %{HTTP_COOKIE} (?:^|;\s*)client=([^;]*) # check if an image was requested RewriteCond %{REQUEST_FILENAME} \.(jpe?g|gif|bmp|png)$ # exclude these folders RewriteCond %{REQUEST_URI} !some/members/logos # grab everything before the variable folder and everything afterwards # replace this with first bracket/cookie_value/second bracket RewriteRule (^.+)/VARIABLE/(.+)$ $1/%1/$2 [L] </IfModule> Still can't get it to work, but I think this is the correct way of doing it. Thanks for help!

• How to access XAMPP virtual hosts from iPad on local network?

  - by martin's

  Using XAMPP on one machine. Multiple virtual hosts defined. One per project. Format is .local For example: apple.local microsoft.local client-site.local our-own-internal-site.local All works perfectly from that one machine. I now want to have other systems within the network access the various sites. The main reason for wanting to do this is to be able to test site functionality and layout from mobile devices without having to upload partial work to public servers. I can access the main XAMPP default site by simply entering the IP address of the XAMPP machine in, say, Safari on an iPad. However, there is no way to reach .local that I can see. Would this entail setting up a DNS server within the network? We have a mixture of Windows and Mac machines. No Linux. The XAMPP machine is Vista 64. I don't want real external internet access to be affected in any way, just ".local" pointed to the XAMPP machine if that makes sense.

• Maven does not resolve a local Grails plug-in

  - by Drew

  My goal is to take a Grails web application and build it into a Web ARchive (WAR file) using Maven, and the key is that it must populate the "plugins" folder without live access to the internet. An "out of the box" Grails webapp will already have the plugins folder populated with JAR files, but the maven build script should take care of populating it, just like it does for any traditional WAR projects (such as WEB-INF/lib/ if it's empty) This is an error when executing mvn grails:run-app with Grails 1.1 using Maven 2.0.10 and org.grails:grails-maven-plugin:1.0. (This "hibernate-1.1" plugin is needed to do GORM.) [INFO] [grails:run-app] Running pre-compiled script Environment set to development Plugin [hibernate-1.1] not installed, resolving.. Reading remote plugin list ... Error reading remote plugin list [svn.codehaus.org], building locally... Unable to list plugins, please check you have a valid internet connection: svn.codehaus.org Reading remote plugin list ... Error reading remote plugin list [plugins.grails.org], building locally... Unable to list plugins, please check you have a valid internet connection: plugins.grails.org Plugin 'hibernate' was not found in repository. If it is not stored in a configured repository you will need to install it manually. Type 'grails list-plugins' to find out what plugins are available. The build machine does not have access to the internet and must use an internal/enterprise repository, so this error is just saying that maven can't find the required artifact anywhere. That dependency is already included with the stock Grails software that's installed locally, so I just need to figure out how to get my POM file to unpackage that ZIP file into my webapp's "plugins" folder. I've tried installing the plugin manually to my local repository and making it an explicit dependency in POM.xml, but it's still not being recognized. Maybe you can't pull down grails plugins like you would a standard maven reference? mvn install:install-file -DgroupId=org.grails -DartifactId=grails-hibernate -Dversion=1.1 -Dpackaging=zip -Dfile=%GRAILS_HOME%/plugins/grails-hibernate-1.1.zip I can manually setup the Grails webapp from the command-line, which creates that local ./plugins folder properly. This is a step in the right direction, so maybe the question is: how can I incorporate this goal into my POM? mvn grails:install-plugin -DpluginUrl=%GRAILS_HOME%/plugins/grails-hibernate-1.1.zip Here is a copy of my POM.xml file, which was generated using an archetype. <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.samples</groupId> <artifactId>sample-grails</artifactId> <packaging>war</packaging> <name>Sample Grails webapp</name> <properties> <sourceComplianceLevel>1.5</sourceComplianceLevel> </properties> <version>0.0.1-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.grails</groupId> <artifactId>grails-crud</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>org.grails</groupId> <artifactId>grails-gorm</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>opensymphony</groupId> <artifactId>oscache</artifactId> <version>2.4</version> <exclusions> <exclusion> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> </exclusion> <exclusion> <groupId>javax.jms</groupId> <artifactId>jms</artifactId> </exclusion> <exclusion> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>hsqldb</groupId> <artifactId>hsqldb</artifactId> <version>1.8.0.7</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.5.6</version> <scope>runtime</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- <dependency> <groupId>org.grails</groupId> <artifactId>grails-hibernate</artifactId> <version>1.1</version> <type>zip</type> </dependency> --> </dependencies> <build> <pluginManagement /> <plugins> <plugin> <groupId>org.grails</groupId> <artifactId>grails-maven-plugin</artifactId> <version>1.0</version> <extensions>true</extensions> <executions> <execution> <goals> <goal>init</goal> <goal>maven-clean</goal> <goal>validate</goal> <goal>config-directories</goal> <goal>maven-compile</goal> <goal>maven-test</goal> <goal>maven-war</goal> <goal>maven-functional-test</goal> </goals> </execution> </executions> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>${sourceComplianceLevel}</source> <target>${sourceComplianceLevel}</target> </configuration> </plugin> </plugins> </build> </project>

• JSON object array to store data of a form in local storage temporary (PhoneGap project)

• How to programmatically add x509 certificate to local machine store using c#

  - by David

  I understand the question title may be a duplicate but I have not found an answer for my situation yet so here goes; I have this simple peice of code // Convert the Filename to an X509 Certificate X509Certificate2 cert = new X509Certificate2(certificateFilePath); // Get the server certificate store X509Store store = new X509Store(StoreName.TrustedPeople, StoreLocation.LocalMachine); store.Open(OpenFlags.MaxAllowed); store.Add(cert); // x509 certificate created from a user supplied filename But keep being presented with an "Access Denied" exception. I have read some information that suggests using StorePermissions would solve my issue but I don't think this is relevant in my code. Having said that, I did test it to to be sure and I couldn't get it to work. I also found suggestions that changing folder permissions within Windows was the way to go and while this may work(not tested), it doesn't seem practical for what will become distributed code. I also have to add that as the code will be running as a service on a server, adding the certificates to the current user store also seems wrong. Is there anyway to programmatically add a certificate into the local machine store?

• Segmentation fault on the server, but not local machine

• Can't connect to local MySQL server through socket

  - by Martin

  I was trying to tune the performance of a running mysql-server by running this command: mysqld_safe --key_buffer_size=64M --table_cache=256 --sort_buffer_size=4M --read_buffer_size=1M & After this i'm unable to connect mysql from the server where mysql is running. I get this error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) However, luckily i can still connect to mysql remotely. So all my webservers still have access to mysql and are running without any problems. Because of this though i don't want to try to restart the mysql server since that will probably fuck everything up. Now i know that mysqld_safe is starting the mysql-server, and since the mysql server was already running i guess it's some kind of problem with two mysql servers running and listening to the same port. Is there some way to solve this problem without restarting the initial mysql server? UPDATE: This is what ps xa | grep "mysql" says: 11672 ? S 0:00 /bin/sh /usr/bin/mysqld_safe 11780 ? Sl 175:04 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock --port=3306 11781 ?

• NSObject release destroys local copy of object's data

  - by Spider-Paddy

  I know this is something stupid on my part but I don't get what's happening. I create an object that fetches data & puts it into an array in a specific format, since it fetches asynchronously (has to download & parse data) I put a delegate method into the object that needs the data so that the data fetching object copies it's formatted array into an array in the calling object. The problem is that when the data fetching object is released, the copy it created in the caller is being erased, code is: In .h file @property (nonatomic, retain) NSArray *imagesDataSource; In .m file // Fetch item details ImagesParser *imagesParserObject = [[ImagesParser alloc] init:self]; [imagesParserObject getArticleImagesOfArticleId:(NSInteger)currentArticleId]; [imagesParserObject release] <-- problematic release // Called by parser when images parsing is finished -(void)imagesDataTransferComplete:(ImagesParser *)imagesParserObject { self.imagesDataSource = [ImagesParserObject.returnedArray copy]; // copy array to local variable // If there are more pics, they must be assembled in an array for possible UIImageView animation NSInteger picCount = [imagesDataSource count]; if(picCount > 1) // 1 image is assumed to be the pic already displayed { // Build image array NSMutableArray *tempPicArray = [[NSMutableArray alloc] init]; // Temp space to hold images while building for(int i = 0; i < picCount; i++) { // Get Nr from only article in detailDataSource & pic name (Small) from each item in imagesDataSource NSString *picAddress = [NSString stringWithFormat:@"http://some.url.com/shopdata/image/article/%@/%@", [[detailDataSource objectAtIndex:0] objectForKey:@"Nr"], [[imagesDataSource objectAtIndex:i] objectForKey:@"Small"]]; NSURL *picURL = [NSURL URLWithString:picAddress]; NSData *picData = [NSData dataWithContentsOfURL:picURL]; [tempPicArray addObject:[UIImage imageWithData:picData]]; } imagesArray = [tempPicArray copy]; // copy makes immutable copy of array [tempPicArray release]; currentPicIndex = 0; // Assume first pic is pic already being shown } else imagesArray = nil; // No need for a needless pic array // Remove please wait message [pleaseWaitViewControllerObject.view removeFromSuperview]; } I put in tons of NSLog lines to keep track of what was going on & self.imagesDataSource is populated with the returned array but when the parser object is released self.imagesDataSource becomes empty. I thought self.imagesDataSource = [ImagesParserObject.returnedArray copy]; is supposed to make an independant object, like as if it was alloc, init'ed, so that self.imagesDataSource is not just a pointer to the parser's array but is it's own array. So why does the release of the parser object clear the copy of the array. (I checked & double checked that it's not something overwriting self.imagesDataSource, commenting out [imagesParserObject release] consistently fixes the problem) Also, I have exactly the same problem with self.detailDataSource which is declared & populated in the exact same way as self.imagesDataSource I thought that once I call the parser I could release it because the caller no longer needs to refer to it, all further activity is carried out by the parser object through it's delegate method, what am I doing wrong?

Errors reported here must be corrected before the service can be started. httpd.exe: Could not reliably determine the server's fully qualified domain name , using 192.168.1.3 for ServerName (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs Note the errors or messages above, and press the key to exit. 24... and after installing everything look fine, but it isn't. If I try to start service I got the following message: Windows could not start the Apache2 on Local Computer. For more information, review the System Event Log. If this is a non-Micorsoft service, contact the service vendor, and refer to service-specific error code 1. Apach2 version is 2.2.9 Does anyone have the same problem, or could help me.

• Using target-specific variable in makefile

  - by James Johnston

  I have the following makefile: OUTPUTDIR = build all: v12target v13target v12target: INTDIR = v12 v12target: DoV12.avrcommontargets v13target: INTDIR = v13 v13target: DoV13.avrcommontargets %.avrcommontargets: $(OUTPUTDIR)/%.elf @true $(OUTPUTDIR)/%.elf: $(OUTPUTDIR)/$(INTDIR)/main.o @echo TODO build ELF file from object file: destination $@, source $^ @echo Compiled elf file for $(INTDIR) > $@ $(OUTPUTDIR)/$(INTDIR)/%.o: %.c @echo TODO call GCC to compile C file: destination $@, source $< @echo Compiled object file for $<, revision $(INTDIR) > $@ $(shell rm -rf $(OUTPUTDIR)) $(shell mkdir -p $(OUTPUTDIR)/v12 2> /dev/null) $(shell mkdir -p $(OUTPUTDIR)/v13 2> /dev/null) .SECONDARY: The idea is that there are several different code configurations that need to be compiled from the same source code. The "all" target depends on v12target and v13 target, which set a number of variables for that particular build. It also depends on an "avrcommontargets" pattern, which defines how to actually do the compiling. avrcommontargets then depends on the ELF file, which in turn depends on object files, which are built from the C source code. Each compiled C file results in an object file (*.o). Since each configuration (v12, v13, etc.) results in a different output, the C file needs to be built several times with the output placed in different subdirectories. For example, "build/v12/main.o", "build/v13/main.o", etc. Sample output: TODO call GCC to compile C file: destination build//main.o, source main.c TODO build ELF file from object file: destination build/DoV12.elf, source build//main.o TODO build ELF file from object file: destination build/DoV13.elf, source build//main.o The problem is that the object file isn't going into the correct subdirectory. For example, "build//main.o" instead of "build/v12/main.o". That then prevents the main.o from being correctly rebuilt to generate the v13 version of main.o. I'm guessing the issue is that $(INTDIR) is a target specific variable, and perhaps this can't be used in the pattern targets I defined for %.elf and %.o. The correct output would be: TODO call GCC to compile C file: destination build/v12/main.o, source main.c TODO build ELF file from object file: destination build/DoV12.elf, source build/v12/main.o TODO call GCC to compile C file: destination build/v13/main.o, source main.c TODO build ELF file from object file: destination build/DoV13.elf, source build/v13/main.o What do I need to do to adjust this makefile so that it generates the correct output?

• IIS SMTP server (Installed on local server) in parallel to Google Apps

  - by sharru

  I am currently using free version of Google Apps for hosting my email.It works great for my official mails my email on Google is [email protected]. In addition I'm sending out high volume mails (registrations, forgotten passwords, newsletters etc) from the website (www.mydomain.com) using IIS SMTP installed on my windows machine. These emails are sent from [email protected] My problem is that when I send email from the website using IIS SMTP to a mail address [email protected] I don’t receive the email to Google apps. (I only receive these emails if I install a pop service on the server with the [email protected] email box). It seems that the IIS SMTP is ignoring the domain MX records and just delivers these emails to my local server. Here are my DNS records for domain.com: mydomain.com A 82.80.200.20 3600s mydomain.com TXT v=spf1 ip4: 82.80.200.20 a mx ptr include:aspmx.googlemail.com ~all mydomain.com MX preference: 10 exchange: aspmx2.googlemail.com 3600s mydomain.com MX preference: 10 exchange: aspmx3.googlemail.com 3600s mydomain.com MX preference: 10 exchange: aspmx4.googlemail.com 3600s mydomain.com MX preference: 10 exchange: aspmx5.googlemail.com 3600s mydomain.com MX preference: 1 exchange: aspmx.l.google.com 3600s mydomain.com MX preference: 5 exchange: alt1.aspmx.l.google.com 3600s mydomain.com MX preference: 5 exchange: alt2.aspmx.l.google.com 3600s Please help!

• Child sProc cannot reference a Local temp table created in parent sProc

  - by John Galt

  On our production SQL2000 instance, we have a database with hundreds of stored procedures, many of which use a technique of creating a #TEMP table "early" on in the code and then various inner stored procedures get EXECUTEd by this parent sProc. In SQL2000, the inner or "child" sProc have no problem INSERTing into #TEMP or SELECTing data from #TEMP. In short, I assume they can all refer to this #TEMP because they use the same connection. In testing with SQL2008, I find 2 manifestations of different behavior. First, at design time, the new "intellisense" feature is complaining in Management Studio EDIT of the child sProc that #TEMP is an "invalid object name". But worse is that at execution time, the invoked parent sProc fails inside the nested child sProc. Someone suggested that the solution is to change to ##TEMP which is apparently a global temporary table which can be referenced from different connections. That seems too drastic a proposal both from the amount of work to chase down all the problem spots as well as possible/probable nasty effects when these sProcs are invoked from web applications (i.e. multiuser issues). Is this indeed a change in behavior in SQL2005 or SQL2008 regarding #TEMP (local temp tables)? We skipped 2005 but I'd like to learn more precisely why this is occuring before I go off and try to hack out the needed fixes. Thanks.

• Losing reference to $_post variable?

  In the code below, the echo at the top returns true, but the echo at the bottom returns nothing. Apparently the code in between is causing me to lose a reference to the $_post variable? <?php echo "in category: ".in_category('is-sidebar', $_post); //RETURNS TRUE if (!get_option('my_hide_recent')) { $cat=get_cat_ID('top-menu'); $catHidden=get_cat_ID('hidden'); $myquery = new WP_Query(); $myquery->query(array( 'cat' => "-$cat,-$catHidden", 'post_not_in' => get_option('sticky_posts') )); $myrecentpostscount = $myquery->found_posts; if ($myrecentpostscount > 0) { ?> <div class="menu"><h4><?php if ($my_sidebar_heading_recent !=="") { echo $my_sidebar_heading_recent; } else { echo "Recent Posts";} ?></h4><ul> <?php global $post; $current_page_recent = get_post( $current_page ); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => $my_recent_count)); foreach($myrecentposts as $idxrecent=>$post) { if($post->ID == $current_page_recent->ID) { $home_menu_recent = ' class="current_page_item'; } else { $home_menu_recent = ' class="page_item'; } $myclassrecent = ($idxrecent == count($myrecentposts) - 1 ? $home_menu_recent.' last"' : $home_menu_recent.'"'); ?> <li<?php echo $myclassrecent ?>><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php } ; if (($myrecentpostscount > $my_recent_count) && $my_recent_count > -1){ ?><li><a href="<?php bloginfo('url'); ?>/site-map">View all</a></li><?php } ?></ul></div> <?php } } global $sitemap; echo "in category: ".in_category('is-sidebar', $_post); //RETURNS NOTHING

• Read variable-length records from a buffer - weird memory issues

  - by bsg

  Hi, I'm trying to implement an i/o intensive quicksort (C++ qsort) on a very large dataset. In the interests of speed, I'd like to read in a chunk of data at a time into a buffer and then use qsort to sort it inside the buffer. (I am currently working with text files but would like to move to binary soon.) However, my data is composed of variable-length records, and qsort needs to be told the length of the record in order to sort. Is there any way to standardize this? The only thing I could think of was rather convoluted: my program currently reads from the buffer until it hits a linefeed character ('10' in ascii), transferring each character over to another array. When it finds a linefeed (the delimiter in the input file), it fills the number of spaces remaining in the buffer for that record (record size is set to 30) with null characters. This way, I should end up with a buffer full of fixed-size records to give qsort. I know there are several problems with my approach, one being that it's just clumsy, another that the record size might conceivably be larger than 30, but is generally much less. Is there a better way of doing this? As well, my current code doesn't even work. When I debug it, it seems to be transferring characters from one buffer to the other, but when I try to print out the buffer, it contains only the first record. Here is my code: FILE *fp; unsigned char *buff; unsigned char *realbuff; FILE *inputFiles[NUM_INPUT_FILES]; buff = (unsigned char *) malloc(2048); realbuff = (unsigned char *) malloc(NUM_RECORDS * RECORD_SIZE); fp = fopen("postings0.txt", "r"); if(fp) { fread(buff, 1, 2048, fp); /*for(int i=0; i <30; i++) cout << buff[i] <<endl;*/ int y=0; int recordcounter = 0; //cout << buff; for(int i=0;i <100; i++) { if(buff[i] != char(10)) { realbuff[y] = buff[i]; y++; recordcounter++; } else { if(recordcounter < RECORD_SIZE) for(int j=recordcounter; j < RECORD_SIZE;j++) { realbuff[y] = char(0); y++; } recordcounter = 0; } } cout << realbuff <<endl; cout << buff; } else cout << "sorry"; Thank you very much, bsg

• PHP: How to implement a __get-like method for local function variables

  - by Tom Frost

  I'm no stranger to __get(), and have used it to make some very convenient libraries in the past. However, I'm faced with a new challenge (PHP 5.3, abbreviated and simplified my code for this question): <?php namespace test; class View { function __construct($filename, $varArray) { $this->filename = $filename; $this->varArray = $varArray; } function display() { include($this->filename); } function __get($varName) { if (isset($this->varArray[$varName])) return $this->varArray[$varName]; return "?? $varname ??"; } } ?> Above is a very, very simplified system for loading a View. This code would call the view and display it: <?php require_once("View.php"); use test\View; $view = new View("views/myview.php", array("user" => "Tom")); $view->display(); ?> My goal for this code is to allow the view "myview.php" to contain code like this: <p> Hello <?php echo $user; ?>! Your E-mail is <?php echo $email; ?> </p> And, used with the above code, this would output "Hello Tom! Your E-mail is ?? email ??" However, this won't work. The view is being included within a class method, so when it refers to $user and $email, it's looking for local function variables -- not variables belonging to the View class. For this reason, __get never gets triggered. I could change all my view's variables to things like $this-user and $this-email, but that would be a messy and unintuitive solution. I'd love to find a way where I can reference variables directly WITHOUT having PHP throw an error when an undefined variable is used. Thoughts? Is there a clean way to do this, or am I forced to resort to hacky solutions?

• xslt test if a variable value is contained in a node set

  I have the following two files: <?xml version="1.0" encoding="utf-8" ?> <!-- D E F A U L T H O S P I T A L P O L I C Y --> <xas DefaultPolicy="open" DefaultSubjectsFile="subjects.xss"> <rule id="R1" access="deny" object="record" subject="roles/*[name()!='Staff']"/> <rule id="R2" access="deny" object="diagnosis" subject="roles//Nurse"/> <rule id="R3" access="grant" object="record[@id=$user]" subject="roles/member[@id=$user]"/> </xas> and the other xml file called subjects.xss is: <?xml version="1.0" encoding="utf-8" ?> <subjects> <users> <member id="dupont" password="4A-4E-E9-17-5D-CE-2C-DD-43-43-1D-F1-3F-5D-94-71"> <name>Pierre Dupont</name> </member> <member id="durand" password="3A-B6-1B-E8-C0-1F-CD-34-DF-C4-5E-BA-02-3C-04-61"> <name>Jacqueline Durand</name> </member> </users> <roles> <Staff> <Doctor> <member idref="dupont"/> </Doctor> <Nurse> <member idref="durand"/> </Nurse> </Staff> </roles> </subjects> I am writing an xsl sheet which will read the subject value for each rule in policy.xas and if the currently logged in user (accessible as variable "user" in the stylesheet) is contained in that subject value (say roles//Nurse), then do something. I am not being able to test whether the currently logged in user ($user which is equal to say "durand") is contained in roles//Nurse in the subjects file (which is a different xml file). Hope that clarifies my question. Any ideas? Thanks in advance.

• Passing data between ViewControllers versus doing local Fetch in each VC

  - by Tofrizer

  Hi All, I'm developing an iPhone app using Core Data and I'm looking for some general advice and recommendations on whether its acceptable to pass data between ViewControllers versus doing a local fetch in each ViewController as you navigate to it. Ordinarily I would say it all depends on various factors (e.g. performance etc) but the passing data approach is so prevalent in my app and I'm spooked by all the stories about Apple rejecting apps because of not conforming to their standard guidelines. So let me put another way -- is it non-standard to pass data between VC's? The reason I pass data so much is because each ViewController is just another view on to data present in my object model / graph. Once I have a handle on my first object in the first view controller (which I of course do have to fetch), I can use the existing object composition / relationships to drill down into the next level of detail into data and so I just pass these objects to the next VC. Separately, one possible downside with this passing-data-to-each-VC approach is I don't benefit from (what I perceive to be) the optimisation/benefits that NSFetchedResultsController provides in terms of efficient memory usage and section handling. My app is read-only but I do have one table with 5000 rows and I'm curious if I am missing out on NSFetchedResultsController benefits. Any thoughts on this as well? Can I somehow still benefit from NSFetchedResultsController goodness without having to do a full fetch (as I would have already passed in the data from my previous VC)? Thanks a lot.

• conflicting declaration when filling a static std::map class member variable
