How to I access "Deny" message from a Lidgren client?

- by TJ Mott

I'm using the Lidgren v3 network for a UDP client/server networking model. On the server end, I'm initializing a NetServer object with the NetIncomingMessage.ConnectionApproval message type enabled. So the client is able to successfully connect and the first packet it sends is a login packet, containing a username and password supplied by the user. The server is receiving that and doing some black magic to authenticate, and everything works up to that point. If the login fails, the server calling NetIncomingMessage.SenderConnection.Deny("Invalid Login Credentials"). I want to know how to properly receive this deny message on the client. I'm getting the message, it shows up with a message type of NetIncomingMessage.StatusChanged. If I call ReadString on that message, I get a corrupted version of the string I passed to the Deny method on the server. The type of corruption varies, I've seen odd characters in there but in every case it's truncated and is way shorter than the string I entered. Any ideas? The official documentation is sparse on this topic. I could use pointers from anyone who has successfully used the Lidgren library and uses the Accept or Deny methods. Also, if I don't do any authentication and just Approve() the connection every time, stuff actually works just fine and I'm getting reliable two-way UDP traffic. (And lastly, Stack Exchange said I don't have enough reputation to use the "Lidgren" tag....???)

PostgreSQL, Ubuntu, NetBeans IDE (Part 3)

- by Geertjan

To complete the picture, let's use the traditional (that is, old) Hibernate mechanism, i.e., via XML files, rather than via the annotations shown yesterday. It's definitely trickier, with many more places where typos can occur, but that's why it's the old mechanism. I do not recommend this approach. I recommend the approach shown yesterday. The other players in this scenario include PostgreSQL, as outlined in the previous blog entries in this series. Here's the structure of the module, replacing the code shown yesterday: Here's the Employee class, notice that it has no annotations: import java.io.Serializable; import java.util.Date; public class Employees implements Serializable { private int employeeId; private String firstName; private String lastName; private Date dateOfBirth; private String phoneNumber; private String junk; public int getEmployeeId() { return employeeId; } public void setEmployeeId(int employeeId) { this.employeeId = employeeId; } public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public Date getDateOfBirth() { return dateOfBirth; } public void setDateOfBirth(Date dateOfBirth) { this.dateOfBirth = dateOfBirth; } public String getPhoneNumber() { return phoneNumber; } public void setPhoneNumber(String phoneNumber) { this.phoneNumber = phoneNumber; } public String getJunk() { return junk; } public void setJunk(String junk) { this.junk = junk; } } And here's the Hibernate configuration file: <?xml version="1.0"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">org.postgresql.Driver</property> <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/smithdb</property> <property name="hibernate.connection.username">smith</property> <property name="hibernate.connection.password">smith</property> <property name="hibernate.connection.pool_size">1</property> <property name="hibernate.default_schema">public"</property> <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property> <property name="hibernate.current_session_context_class">thread</property> <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property> <property name="hibernate.show_sql">true</property> <mapping resource="org/db/viewer/employees.hbm.xml"/> </session-factory> </hibernate-configuration> Next, the Hibernate mapping file: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="org.db.viewer.Employees" table="employees" schema="public" catalog="smithdb"> <id name="employeeId" column="employee_id" type="int"> <generator class="increment"/> </id> <property name="firstName" column="first_name" type="string" /> <property name="lastName" column="last_name" type="string" /> <property name="dateOfBirth" column="date_of_birth" type="date" /> <property name="phoneNumber" column="phone_number" type="string" /> <property name="junk" column="junk" type="string" /> </class> </hibernate-mapping> Then, the HibernateUtil file, for providing access to the Hibernate SessionFactory: import java.net.URL; import org.hibernate.cfg.AnnotationConfiguration; import org.hibernate.SessionFactory; public class HibernateUtil { private static final SessionFactory sessionFactory; static { try { // Create the SessionFactory from standard (hibernate.cfg.xml) // config file. String res = "org/db/viewer/employees.cfg.xml"; URL myURL = Thread.currentThread().getContextClassLoader().getResource(res); sessionFactory = new AnnotationConfiguration().configure(myURL).buildSessionFactory(); } catch (Throwable ex) { // Log the exception. System.err.println("Initial SessionFactory creation failed." + ex); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } } Finally, the "createKeys" in the ChildFactory: @Override protected boolean createKeys(List list) { Session session = HibernateUtil.getSessionFactory().getCurrentSession(); Transaction transac = null; try { transac = session.beginTransaction(); Query query = session.createQuery("from Employees"); list.addAll(query.list()); } catch (HibernateException he) { Exceptions.printStackTrace(he); if (transac != null){ transac.rollback(); } } finally { session.close(); } return true; } Note that Constantine Drabo has a similar article here. Run the application and the result should be the same as yesterday.

C++11 Tidbits: access control under SFINAE conditions

- by Paolo Carlini

Lately I have been spending quite a bit of time on the SFINAE ("Substitution failure is not an error") features of C++, fixing and tweaking various bits of the GCC implementation. An important missing piece was the implementation of the resolution of DR 1170 which, in a nutshell, mandates that access checking is done as part of the substitution process. Consider: class C { typedef int type; }; template <class T, class = typename T::type> auto f(int) - char; template <class> auto f(...) -> char (&)[2]; static_assert (sizeof(f<C>(0)) == 2, "Ouch"); According to the resolution, the static_assert should not fire, and the snippet should compile successfully. The reason being that the first f overload must be removed from the candidate set because C::type is private to C. On the other hand, before the resolution of DR 1170, the expected behavior was for the first overload to remain in the candidate set, win over the second one, to eventually lead to an access control error (*). GCC mainline (would be 4.8) finally implements the DR, thus benefiting the many modern programming techniques heavily exploiting SFINAE, among which certainly the GNU C++ runtime library itself, which relies on it for the internals of <type_traits> and in several other places. Note that the resolution of the DR is active even in C++98 mode, not just in C++11 mode, because it turned out that the traditional behavior, as implemented in GCC, wasn't fully consistent in all the possible circumstances. (*) In practice, GCC didn't really implement this, the static_assert triggered instead.

Formal definition for term "pure OO language"?

- by Yauhen Yakimovich

I can't think of a better place among SO siblings to pose such a question. Originally I wanted to ask "Is python a pure OO language?" but considering troubles and some sort of discomfort people experience while trying to define the term I decided to start with obtaining a clear definition for the term itself. It would be rather fair to start with correspondence by Dr. Alan Kay, who has coined the term (note the inspiration in biological analogy to cells or other living objects). There are following ways to approach the task: Give a comparative analysis by listing programming languages that exhibits certain properties unique and sufficient to define the term (although Smalltalk and Java are passing examples but IMO this way seems neither really complete or nor fruitful) Give a formal definition (or close to it, e.g. in more academic or mathematical style). Give a philosophical definition that would totally rely on semantical context of concrete language or a priori programming experience (there must be some chance of successful explanation by the community). My current version: "If a certain programing (formal) language that can (grammatically) differentiate between operations and operands as well as infer about the type of each operand whether this type is an object (in sense of OOP) or not then we call such a language an OO-language as long as there is at least one type in this language which is an object. Finally, if all types of the language are also objects we define such language to be pure OO-language." Would appreciate any possible improvement of it. As you can see I just made the definition dependent on the term "object" (often fully referenced as class of objects).

10.10 boots to command line login prompt

- by greggory.hz

I recently installed Ubuntu 10.10 on a computer that was previously running 10.04 (that worked fine). Now, each time I boot up, it starts up in a command line login prompt. I can login and it stays at the command line (as expected). I can then manually start gdm with sudo start gdm and it works fine. I can also enable compiz (using proprietary nvidia drivers) so I'm reasonably confident that it's not a driver problem (at least not in the sense that the drivers just flat out aren't working). Interestingly, if I leave it at the command prompt without logging in, after about 5 or 10 minutes, gnome starts up on its own. I'm not sure what is causing this. This is what dmesg | tail gives me after a manual start of gdm: [ 15.664166] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 270.18 Tue Jan 18 21:46:26 PST 2011 [ 15.991304] type=1400 audit(1297543976.953:11): apparmor="STATUS" operation="profile_load" name="/usr/share/gdm/guest-session/Xsession" pid=990 comm="apparmor_parser" [ 16.606986] eth0: link up, 100Mbps, full-duplex, lpa 0xCDE1 [ 18.798506] EXT4-fs (sda1): re-mounted.

How to recover from terminal custom setup

- by linq

I installed ubuntu 12.04 and I added "Terminal" to the launcher bar, the default size of the terminal is a bit small, after some googling here is how I made the disaster change: At HUD menu, type "preference" and I see the option of Edit > preference, this is as I expected After I clicked the option, I forget the exact steps, but somehow I came to some configuration panel and there is a checkbox for terminal "custom" and I checked it now an input box is enabled and I type gnome-terminal --geometry 160x50 Now the problem comes, whenever I click the terminal button at the launcher bar, new terminal windows pops up endlessly from everywhere, I cannot do anything any more except logout or shutdown. The weird thing is, after I come back, I cannot get that Edit > preference any more when I type "preference" in HUD, I tried "Edit", "preference". To be clear, I still can use the computer as long as I do not click that terminal button, but I really want to use terminal to run commands. Help is appreciated greatly! Update - OK, figured out. Go to /home/jibin/.gconf/apps/gnome-terminal/profiles/Default and open that xml file, I can see the options I changed at the GUI, remove them and terminal runs good. The preference HUD is back also, it is actually Profile Preference and it is only available when terminal is open. Continue my ubuntu-ing...

GPTsync mismatch problem

- by user86762

I have a hybrid disk. After trying to copy some files from another disk to this one, I lost my OSX and Ubuntu boot capability. Ran gptsync and got: Current GPT partition table: # Start LBA End LBA Type 1 34 1987 BIOS Boot Partition 2 1988 1029662719 Basic Data 3 1029662720 2108995583 Basic Data 4 2108995584 2109405183 EFI System (FAT) 5 2109405184 2517004287 Mac OS X HFS+ 6 2517266432 2667417599 Mac OS X HFS+ 7 2667417600 3900229631 Basic Data 8 3900230504 3907029118 Linux Swap Current MBR partition table: # A Start LBA End LBA Type 1 1 3907029167 ee EFI Protective Status: MBR table must be updated.

[y/N] Clearly the MBR table is damaged or mismatched. But it does not reflect the correct GPT table partitions at all. How do I get the MBR repaired to match the GPT table (up to the 4 part limit of course)? The question is simply - Do I blindly say Yes to gptsync's suggestion? It looks sort of ok but not exactly so...Advice please on interpreting the above output to get my disk usable would be greatly appreciated. Thank You!

Cloned partition not seen correctly by disk utility & gparted

- by enrico

Some days ago I cloned my /dev/sda1 partition with clonezilla in partition-to-partition mode to /dev/sda3. It worked, but now that I've finished the setup of system in /dev/sda3, I wanna reinstall /dev/sda1 for other stuffs. This partition is NOT mounted, but ubuntu's DISK UTILITY thinks it is, while it doesn't see as mounted the currently active / partition /dev/sda3. This is the df- TH output : Filesystem Type Size Used Avail Use% Mounted on /dev/sda3 ext4 32G 6.2G 24G 21% / udev devtmpfs 2.2G 13k 2.2G 1% /dev tmpfs tmpfs 845M 906k 844M 1% /run none tmpfs 5.3M 0 5.3M 0% /run/lock none tmpfs 2.2G 115k 2.2G 1% /run/shm /dev/sdb1 fuseblk 321G 147G 174G 46% /Dati Gparted instead, sees /dev/sda1 as NOT mounted (checked with Information option), but it display the BOOT flag on this partition, while the real booted partition /dev/sda3, hasn't it. If I try to format the /dev/sda1 partition, it gives me this error : GParted 0.8.1 --enable-libparted-dmraid Libparted 2.3 Format /dev/sda1 as ext2 00:00:02 ( ERROR ) calibrate /dev/sda1 00:00:00 ( SUCCESS ) path: /dev/sda1 start: 2048 end: 62500863 size: 62498816 (29.80 GiB) set partition type on /dev/sda1 00:00:02 ( SUCCESS ) new partition type: ext2 create new ext2 file system 00:00:00 ( ERROR ) mkfs.ext2 -L "" /dev/sda1 mke2fs 1.41.14 (22-Dec-2010) /dev/sda1 is mounted; will not make a filesystem here! How is possible to correct this behaviour ? Is this due to some lacking option in clonezilla phase ? TIA Enrico

Save password in WCF adapter binding file

- by Edmund Zhao

Binding file for WCF Adapter doesn't save the password no matter it is generated by "Add Generated Items..." wizard in Visual Studio or "Export Bindings..." in administration console. It is by design dut to the consideration of security, but it is very annoying especially when you import bindings which contain multiple WCF send ports. The way to aviod retyping password everytime after an import is to edit the binding file before import. Here is what needs to be done. 1. Find the following string: <Password vt="1" /> "<" means "<", ">" means ">", "vt" means "Variable Type", variable type 1 is "NULL", so the above string can be translated to "<Password/>" 2. Replace it with: <Password vt="8">MyPassword</Password> variable type 8 is "string", the above string can be transalted to "<Password>MyPassword</Password>" Binding file uses a lot of character entity references for XML character encoding purpose. For a list of the special charactor entiy references, you can check from here. ...Edmund Zhao

What are the most commonly used and basic Apache htaccess redirects?

- by bybe

This question is here so we can offer users who are looking for information on how to make one or more common or basic redirects in Apache using the htaccess file. All future questions pertaining to finding information that is that is covered by the question should be closed as a duplication of this question. As per this Meta question. Whats the point in this question? The idea while not perfect is catch the most commonly asked questions regarding redirects using the htaccess on the Apache platform either on some type of lamp or a live server. The type of answers should be generally those that you could imagine are used by 100,000’s of sites world-wide and are constantly asked here at Pro Webmasters repeatedly over and over in various forms. A few examples of the type of answers we are looking for: How can I redirect non-www to www? How can I redirect a sub domain to the main domain? How can I redirect a sub folder from domain to a root or a subdomain? How can I redirect an old URL to a new URL? A few examples of the types of answers that we are not looking for: Answers that do not involve a redirect. Any answers relating to NGinx, IIS or any other non-Apache platform. Answers that involve custom and complex string or query removals. Resources for Advanced to Complex Mod_Rewrite Rules: Everything you ever wanted to know about mod rewrite rules but were afraid to ask Please note: that this question is still in construction and may need some refining either by myself or a real moderator of Pro Webmasters, if you have any concerns or questions please use the meta page I made a few days back here.

Keeping Xv Overlay configuration throughout an X session.

- by kriss

After upgrading my Linux system from Ubuntu 9.04 to Ubuntu 10.10, I suceeded correcting most problems (all related to Intel 82865G Integrated Graphics Adapter support and compiz is still not working but that's another matter) but for one I only have a partial solution. Whenever I play a video the colors are much too saturated. This is really a problem for tones of skins that appears reddish (everyone seems to be coming back from a ski vacation with deep sun burns). As this effect only occurs with videos, not with pictures, I finally figured out it was related to Video Overlays configuration and I can correct it typing: xvattr -a XV_SATURATION -v 120 This change the default saturation value, which is 500 and much too high in my case, at eye sight the correct value seems to be between 100 and 150. Now my problem is that I have to type the above command each time I run a video. If I type it before running the video it has no effect, if I close the video and open a new one, I have to type it again, etc. I tried to put it in Xsession and (logically) it has no effect either. How could I do to get the correct setting whenever I run a video without typing the above command every time ?

What did programmers do before variable scope, where everything is global?

- by hydroparadise

So, I am having to deal with seemingly archiac language (called PowerOn) where I have a main method, a few datatypes to define variables with, and has the ability to have sub-procedures (essentially void methods) that does not return a type nor accepts any arguements. The problem here is that EVERYTHING is global. I've read of these type of languages, but most books take the aproach "Ok, we use to use a horse and cariage, but now, here's a car so let's learn how to work on THAT!" We will NEVER relive those days". I have to admit, the mind is struggling to think outside of scope and extent. Well here I am. I am trying to figure out how to best manage nothing but global variables across several open methods. Yep, even iterators for for loops have to be defined globaly, which I find myself recycling in different parts of my code. My Question: for those that have this type experience, how did programmers deal with a large amount of variables in a global playing field? I have feeling it just became a mental juggling trick, but I would be interested to know if there were any known aproaches.

Designing spawning system

- by Vlad

I played this game recently http://www.kongregate.com/games/JuicyBeast/knightmare-tower and I am amazed by the way how different monsters are beign spawned. I personally developed my own shooter game and I added time based but also count based spawing system. By count based I mean when there are 5 enemies on stage stop spawning. But this is one example. My question is how are these spawning mechanism built, is there some pattern or some theory how they are built? Are there some online materials/pages where I can improve my knowledge? To sumarize, let just say we have 6 types of monsters. I start the game and kill of monsters of type 1,2 and 3 all the time. Once I pass the first ceiling, like in the game above, monster type 4 appear. ANd so on. As I progress trough the game, the same system of 6 types of monsters stay, but they become more and more resilient and dangerous. So I must also improve to be able to destroy the same monsters but now stronger. My question is simple, are there some theories built or written for developing this type of inteligent systems? Note: This is a general question, not tied up with some game or how exactly should the game work. I am capable to program my own mechanisms but I think I need some help. Thanks.

mod_rewrite works within directory not on root

- by Anvesh Saxena

I am having problem in my RewriteRule for the tags portion. What I am able to debug is that the rule is been triggered at least because the page "tags.php" is been rendered but without the URL parameters. This .htaccess file with the rules is within root for my sub-domain and has following content for tags postion. # Rewrite rule for tags RewriteRule ^tags/(\w+)/(\d+)/?$ tags.php?tag_name=$1&tag_id=$2 RewriteRule ^tags/(\w+)/?$ tags.php?tag_name=$1 RewriteRule ^tags/?$ tags.php?tag_name= Another problem that I ain't able to debug is that the similar .htaccess file exists for a directory within my sub domain and is working as expected with the necessary URL parameters also been available. The .htaccess file within the directory reads as follows # Rewrite rule for tags RewriteRule ^tags/(\w+)/(\d+)/?$ restAPI.php?type=tags&tag_name=$1&tag_id=$2 RewriteRule ^tags/(\w+)/?$ restAPI.php?type=tags&tag_name=$1 RewriteRule ^tags/?$ restAPI.php?type=tags&tag_name= Could anyone point me the problem that I might be having in my Rewrite rules, I am also facing Internal server error sometimes which I am second guessing is due to the linked problem. Note:- I have Apache version 2.2.23 on my shared hosting.

How to read default key value with dconf or gsettings?

- by Zta

I would like to know the default value of a dconf/gsettings key. My question is a followup of the question below: Where can I get a list of SCHEMA / PATH / KEY to use with gsettings? What I'm trying to do, so create a script that reads all my personal preferences so I can back them up and restore them. I plan to iterate though all keys, like the script above, see what keys have been changed from their default value, and make a note of these, that can be restored later. I see that the dconf-editor display the keys' default value, but I'd very much like to script this. Also, I don't see how parsing the schemas /usr/share/glib-2.0/schemas/ can be automated. Maybe someone can help? gsettings get-default|list-defaults would be nice =) (Geesh, it was much easier in the old days where you just kept your ~/.somethingrc in subversion ... =\ Based on the answer given below, I've updated the script to print schema, key, key's data type, default value, and actual value: #!/bin/bash for schema in $(gsettings list-schemas | sort); do for key in $(gsettings list-keys $schema | sort); do type="$(gsettings range $schema $key | tr "\n" " ")" default="$(XDG_CONFIG_HOME=/tmp/ gsettings get $schema $key | tr "\n" " ")" value="$(gsettings get $schema $key | tr "\n" " ")" echo "$schema :: $key :: $type :: $default :: $value" done done This workaround basically covers what I need. I'll continue working on the backup scrip from here.

Dynamic Layout in BI Publisher

- by Manoj Madhusoodanan

This blog tells about how to set dynamic layout of a BI Publisher report.Lets take a simple business scenario.If user wants to view the output in either PDF or EXCEL.Two ways we can achieve this. 1) If the output type is not a program parameter the we can choose the layout type at the time of submission in the SRS window. 2) If the report output type is a parameter we need to choose the layout at the time of submission of the request using FND_REQUEST.ADD_LAYOUT. Here I am discussing the second approach.Following components I have created for this scenario. 1) XXCUST - Sample Report : This program actually generates the XML data. It is linked with a RTF template.Note: At the time of creating this program you can uncheck Use in SRS to prevent users from submitting from SRS window.Because we are submitting this program from another concurrent program.Also is not required to add it to request group.2) XXCUST - Report Wrapper : This program calls XXCUST - Sample Report and exposed to user through SRS.3) SAMPLE_REPORT_WRAPPER : Executable which calls xxcust_sample_rep.main4) SAMPLE_REPORT_EXE : Executable which calls xxcust_sample_rep.report_main5) XXCUST - Sample Report Data Definition : Data Definition linked to XXCUST - Sample Report6) XXCUST - Sample Report Template : Template linked to XXCUST - Sample Report Data Definition 7) Package 8) RTF

Method for spawning enemies according to player score and game time

- by Sun

I'm making a top-down shooter and want to scale the difficulty of the game according to what the score is and how much time has Passed. Along with this, I want to spawn enemies in different patterns and increase the intervals at which these enemies are shown. I'm going for a similar effect to Geometry wars. However, I can think of a to do this other than have multiple if-else statments, e.g. : if (score > 1000) { //spawn x amount if enemies } else if (score > 10000) { //spawn x amount of enemy type 1 & 2 } else if (score > 15000) { //spawn x amount of enemy type 1 & 2 & 3 } else if (score > 25000) { //spawn x amount of enemy type 1 & 2 & 3 //create patterns with enemies } ...etc What would be a better method of spawning enemies as I have described?

Should I use an interface when methods are only similar?

- by Joshua Harris

I was posed with the idea of creating an object that checks if a point will collide with a line: public class PointAndLineSegmentCollisionDetector { public void Collides(Point p, LineSegment s) { // ... } } This made me think that if I decided to create a Box object, then I would need a PointAndBoxCollisionDetector and a LineSegmentAndBoxCollisionDetector. I might even realize that I should have a BoxAndBoxCollisionDetector and a LineSegmentAndLineSegmentCollisionDetector. And, when I add new objects that can collide I would need to add even more of these. But, they all have a Collides method, so everything I learned about abstraction is telling me, "Make an interface." public interface CollisionDetector { public void Collides(Spatial s1, Spatial s2); } But now I have a function that only detects some abstract class or interface that is used by Point, LineSegment, Box, etc.. So if I did this then each implementation would have to to a type check to make sure that the types are the appropriate type because the collision algorithm is different for each different type match up. Another solution could be this: public class CollisionDetector { public void Collides(Point p, LineSegment s) { ... } public void Collides(LineSegment s, Box b) { ... } public void Collides(Point p, Box b) { ... } // ... } But, this could end up being a huge class that seems unwieldy, although it would have simplicity in that it is only a bunch of Collide methods. This is similar to C#'s Convert class. Which is nice because it is large, but it is simple to understand how it works. This seems to be the better solution, but I thought I should open it for discussion as a wiki to get other opinions.

Anonymouse VS Logged in users on my site & Google Analytics

- by Flowpoke

I'd like to be able to run two different 'tracks' for Google Analytics; One for anonymous users of the site and another for Users whom are logged-in. I say "track" because Im not sure of the term--but I definitely know I want it to all be in the same "Analytics Account", I just want to segregate my logged-in users... In the site template, I can very easily add a conditional to display one or the other (Analytics code snippet)... Which Im hoping this comes down to and although Im not sure, it seems that the last digit in your Analytics ID (e.g. UA-15XXXX0-X) could be incremented to gain such additional 'tracks'....? Any tips? Am I doin it wrong? My current footer snippet: <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try { var pageTracker = _gat._getTracker("UA-XXXXXXX-1"); pageTracker._trackPageview(); } catch(err) {} </script>

How can I making Twitter, Facebook and Reddit share buttons load last?

- by Daniel Bingham

I have a website with a number of pages that sport twitter, facebook and reddit share buttons. They take forever to load and until they do the rest of the page doesn't load. So how I can make them load last? Currently, they are loaded something like this: <div class="item"><a href="http://twitter.com/share" class="twitter-share-button" data-count="vertical" data-via="FridgeToFood" data-related="danielBingham:Recipe and update tweets from Fridge to Food.">Tweet</a><script type="text/javascript" src="http://platform.twitter.com/widgets.js"></script></div> <div class="item"><script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script><fb:like layout="box_count" width="40"></fb:like></div> <div class="item"> <script type="text/javascript">reddit_target='recipes';</script> <script type="text/javascript" src="http://reddit.com/static/button/button2.js"></script> </div> They are in a div called "shareWrapper" and are loading to one side of the page. The buttons load where ever the script code is placed. As far as I know, I can't place the script code at the bottom of the page and move the resulting buttons after the fact. I want them to appear near the top, which right now means they are stopping everything below them from loading for several seconds. I tried loading them using javascript, but using JQuery's $(document).ready(), but that failed. It seems to leave the page in some sort of loading loop from which it never emerges. Are there other ways to get these to load last?

Looking into the jQuery LazyLoad Plugin

- by nikolaosk

I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client side of web development. You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery LazyLoad Plugin.If you want you can have a look at this post, where I describe the JQuery Cycle Plugin.You can find another post of mine talking about the JQuery Carousel Lite Plugin here. Another post of mine regarding the JQuery Image Zoom Plugin can be found here. You can have a look at the JQuery Overlays Plugin here . There are times when when I am asked to create a very long page with lots of images.My first thought is to enable paging on the proposed page. Imagine that we have 60 images on a page. There are performance concerns when we have so many images on a page. Paging can solve that problem if I am allowed to place only 5 images on a page.Sometimes the customer does not like the idea of the paging.Believe it or not some people find the idea of paging not attractive at all.In that case I need a way to only load the initial set of images and as the user scrolls down the page to load the rest.So as someone scrolls down new requests are made to the server and more images are fetched. I can accomplish that with the jQuery LazyLoad Plugin.This is just a plugin that delays loading of images in long web pages.The images that are outside of the viewport (visible part of web page) won't be loaded before the user scrolls to them. Using jQuery LazyLoad Plugin on long web pages containing many large images makes the page load faster. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like. You can use Visual Studio 2012 Express edition. You can download it here. You can download this plugin from this link. I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5)<!DOCTYPE html><html lang="en"> <head> <title>Liverpool Legends</title> <script type="text/javascript" src="jquery-1.8.3.min.js"></script> <script type="text/javascript" src="jquery.lazyload.min.js" ></script></head> <body> <header> <h1>Liverpool Legends</h1> </header> <div id="main"> <img src="barnes.JPG" width="800" height="1100" /><p /> <img src="dalglish.JPG" width="800" height="1100" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p /> </div> <footer> <p>All Rights Reserved</p> </footer> <script type="text/javascript"> $(function () { $("img.LiverpoolImage").lazyload(); }); </script> </body> </html> This is a very simple markup. I have added references to the JQuery library (current version is 1.8.3) and the JQuery LazyLoad Plugin. Firstly, I add two images <img src="barnes.JPG" width="800" height="1100" /><p /> <img src="dalglish.JPG" width="800" height="1100" /><p /> that will load immediately as soon as the page loads. Then I add the images that will not load unless they become active in the viewport. I have all my img tags pointing the src attribute towards a placeholder image. I’m using a blank 1×1 px grey image,loader.gif.The five images that will load as the user scrolls down the page follow. <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p /> <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p /> Then we need to rename the image src to point towards the proper image placeholder. The full image URL goes into the data-original attribute.The Javascript code that makes it all happen follows. We need to make a call to the JQuery LazyLoad Plugin. We add the script just before we close the body element. <script type="text/javascript"> $(function () { $("img.LiverpoolImage").lazyload(); }); </script>We can change the code above to incorporate some effects. <script type="text/javascript"> $("img.LiverpoolImage").lazyload({ effect: "fadeIn" }); </script> That is all I need to write to achieve lazy loading. It it true that you can do so much with less!!I view my simple page in Internet Explorer 10 and it works as expected. I have tested this simple solution in all major browsers and it works fine. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

What conventions or frameworks exist for MVVM in Perl?

- by Will Sheppard

We're using Catalyst to render lots of webforms in what will become a large application. I don't like the way all the form data is confusingly into a big hash in the Controller, before being passed to the template. It seems jumbled up and messy for the template. I'm sure there are real disadvantages that I haven't described properly... Are there? One solution is to just decide on a convention for the hash, e.g.: { defaults => { type => ['a', 'b', 'c'] }, input => { type => 'a' }, output => { message => "2 widgets found of type a", widgets => [ 'foo', 'bar' ] } } Another way is to store the page/form data as attributes in a class (a ViewModel?), and pass a whole object to the template, which it could use like this: <p class="message">[% model.message %]<p> [% FOREACH widget IN model.widgets %] Which way is more flexible for large applications? Are there any other solutions or existing Catalyst-compatible frameworks?

CMS for coding blog

- by OrgnlDave

I've got a server with a LAMP stack and such. I'd like to host a blog-type site (or if there's a free place good for this, that would be cool!) that covers a variety of tutorials, interesting content, etc. There are tons of CMS's out there but if you search for tips on ones that do programming type things well, you get tons of hits about web development. I'd like to know if anyone here has recommendations from actually using a CMS for this type of thing or, short of that, can recommend one - not based on generalities like "Joomla! is great!" I'm looking for the least setup time possible. I'm proficient with CSS and I can design a color scheme, so that's not a big problem. As you can expect, attaching files, pictures, and syntax highlighting are musts (C/C++ ish is good). Ability to group posts, perhaps use tags, etc. would be cool too, but not necessary. As I'm writing this, it almost sounds like it'd be easier to custom-code a small PHP site myself.
