Optimizing a 3D World Javascript Animation

- by johnny

Hi! I've recently come up with the idea to create a tag cloud like animation shaped like the earth. I've extracted the coastline coordinates from ngdc.noaa.gov and wrote a little script that displayed it in my browser. Now as you can imagine, the whole coastline consists of about 48919 points, which my script would individually render (each coordinate being represented by one span). Obviously no browser is capable of rendering this fluently - but it would be nice if I could render as much as let's say 200 spans (twice as much as now) on my old p4 2.8 Ghz (as a representative benchmark). Are there any javascript optimizations I could use in order to speed up the display of those spans? One 'coordinate': <div id="world_pixels"> <span id="wp_0" style="position:fixed; top:0px; left:0px; z-index:1; font-size:20px; cursor:pointer;cursor:hand;" onmouseover="magnify_world_pixel('wp_0');" onmouseout="shrink_world_pixel('wp_0');" onClick="set_askcue_bar('', 'new york')">new york</span> </div> The script: $(document).ready(function(){ world_pixels = $("#world_pixels span"); world_pixels.spin(); setInterval("world_pixels.spin()",1500); }); z = new Array(); $.fn.spin = function () { for(i=0; i<this.length; i++) { /*actual screen coordinates: x/y/z --> left/font-size/top 300/13/0 300/6/300 | / |/ 0/13/300 ----|---- 600/13/300 /| / | 300/20/300 300/13/600 */ /*scale font size*/ var resize_x = 1; /*scale width*/ var resize_y = 2.5; /*scale height*/ var resize_z = 2.5; var from_left = 300; var from_top = 20; /*actual math coordinates: 1 -1 | / |/ 1 ----|---- -1 /| / | 1 -1 */ //var get_element = document.getElementById(); //var font_size = parseInt(this.style.fontSize); var font_size = parseInt($(this[i]).css("font-size")); var left = parseInt($(this[i]).css("left")); if (coast_line_array[i][1]) { } else { var top = parseInt($(this[i]).css("top")); z[i] = from_top + (top - (300 * resize_z)) / (300 * resize_z); //global beacause it's used in other functions later on var top_new = from_top + Math.round(Math.cos(coast_line_array[i][2]/90*Math.PI) * (300 * resize_z) + (300 * resize_z)); $(this[i]).css("top", top_new); coast_line_array[i][3] = 1; } var x = resize_x * (font_size - 13) / 7; var y = from_left + (left- (300 * resize_y)) / (300 * resize_y); if (y >= 0) { this[i].phi = Math.acos(x/(Math.sqrt(x^2 + y^2))); } else { this[i].phi = 2*Math.PI - Math.acos(x/(Math.sqrt(x^2 + y^2))); i } this[i].theta = Math.acos(z[i]/Math.sqrt(x^2 + y^2 + z[i]^2)); var font_size_new = resize_x * Math.round(Math.sin(coast_line_array[i][4]/90*Math.PI) * Math.cos(coast_line_array[i][0]/180*Math.PI) * 7 + 13); var left_new = from_left + Math.round(Math.sin(coast_line_array[i][5]/90*Math.PI) * Math.sin(coast_line_array[i][0]/180*Math.PI) * (300 * resize_y) + (300 * resize_y)); //coast_line_array[i][6] = coast_line_array[i][7]+1; if ((coast_line_array[i][0] + 1) > 180) { coast_line_array[i][0] = -180; } else { coast_line_array[i][0] = coast_line_array[i][0] + 0.25; } $(this[i]).css("font-size", font_size_new); $(this[i]).css("left", left_new); } } resize_x = 1; function magnify_world_pixel(element) { $("#"+element).animate({ fontSize: resize_x*30+"px" }, { duration: 1000 }); } function shrink_world_pixel(element) { $("#"+element).animate({ fontSize: resize_x*6+"px" }, { duration: 1000 }); } I'd appreciate any suggestions to optimize my script, maybe there is even a totally different approach on how to go about this. The whole .js file which stores the array for all the coordinates is available on my page, the file is about 2.9 mb, so you might consider pulling the .zip for local testing: metaroulette.com/files/31218.zip metaroulette.com/files/31218.js P.S. the php I use to create the spans: <?php //$arbitrary_characters = array('a','b','c','ddsfsdfsdf','e','f','g','h','isdfsdffd','j','k','l','mfdgcvbcvbs','n','o','p','q','r','s','t','uasdfsdf','v','w','x','y','z','0','1','2','3','4','5','6','7','8','9',); $arbitrary_characters = array('cat','table','cool','deloitte','askcue','what','more','less','adjective','nice','clinton','mars','jupiter','testversion','beta','hilarious','lolcatz','funny','obama','president','nice','what','misplaced','category','people','religion','global','skyscraper','new york','dubai','helsinki','volcano','iceland','peter','telephone','internet', 'dialer', 'cord', 'movie', 'party', 'chris', 'guitar', 'bentley', 'ford', 'ferrari', 'etc', 'de facto'); for ($i=0; $i<96; $i++) { $arb_digits = rand (0,45); $arbitrary_character = $arbitrary_characters[$arb_digits]; //$arbitrary_character = "."; echo "<span id=\"wp_$i\" style=\"position:fixed; top:0px; left:0px; z-index:1; font-size:20px; cursor:pointer;cursor:hand;\" onmouseover=\"magnify_world_pixel('wp_$i');\" onmouseout=\"shrink_world_pixel('wp_$i');\" onClick=\"set_askcue_bar('', '$arbitrary_character')\">$arbitrary_character</span>\n"; } ?>

Project Management Helps AmeriCares Deliver International Aid

- by Sylvie MacKenzie, PMP

Excerpt from PROFIT - ORACLE - by Alison Weiss Handle with Care Sound project management helps AmeriCares bring international aid to those in need. The stakes are always high for AmeriCares. On a mission to restore health and save lives during times of disaster, the nonprofit international relief and humanitarian aid organization delivers donated medicines, medical supplies, and humanitarian aid to people in the U.S. and around the globe. Founded in 1982 with the express mission of responding as quickly and efficiently as possible to help people in need, the Stamford, Connecticut-based AmeriCares has delivered more than US$10.5 billion in aid to 147 countries over the past three decades. Launch the Slideshow “It’s critically important to us that we steward all the donations and that the medical supplies and medicines get to people as quickly as possible with no loss,” says Kate Sears, senior vice president for finance and technology at AmeriCares. “Whether we’re shipping IV solutions to victims of cholera in Haiti or antibiotics to Somali famine victims, we need to get the medicines there sooner because it means more people will be helped and lives improved or even saved.” Ten years ago, the tracking systems used by AmeriCares associates were paper-based. In recent years, staff started using spreadsheets, but the tracking processes were not standardized between teams. “Every team was tracking completely different information,” says Megan McDermott, senior associate, Sub-Saharan Africa partnerships, at AmeriCares. “It was just a few key things. For example, we tracked the date a shipment was supposed to arrive and the date we got reports from our partner that a hospital received aid on their end.” While the data was accurate, much detail was being lost in the process. AmeriCares management knew it could do a better job of tracking this enterprise data and in 2011 took a significant step by implementing Oracle’s Primavera P6 Professional Project Management. “It’s a comprehensive solution that has helped us improve the monitoring and controlling processes. It has allowed us to do our distribution better,” says Sears. In addition, the implementation effort has been a change agent, helping AmeriCares leadership rethink project management across the entire organization. Initially, much of the focus was on standardizing processes, but staff members also learned the importance of thinking proactively to prevent possible problems and evaluating results to determine if goals and objectives are truly being met. Such data about process efficiency and overall results is critical not only to AmeriCares staff but also to the donors supporting the organization’s life-saving missions. Efficiency Saves Lives One of AmeriCares’ core operations is to gather product donations from the private sector, establish where the most-urgent needs are, and solicit monetary support to send the aid via ocean cargo or airlift to welfare- and health-oriented nongovernmental organizations, hospitals, health networks, and government ministries based in areas in need. In 2011 alone, AmeriCares sent more than 3,500 shipments to 95 countries in response to both ongoing humanitarian needs and more than two dozen emergencies, including deadly tornadoes and storms in the U.S. and the devastating tsunami in Japan. When it comes to nonprofits in general, donors want to know that the charitable organizations they support are using funds wisely. Typically, nonprofits are evaluated by donors in terms of efficiency, an area where AmeriCares has an excellent reputation: 98 percent of expenses go directly to supporting programs and less than 2 percent represent administrative and fundraising costs. Donors, however, should look at more than simple efficiency, says Peter York, senior partner and chief research and learning officer at TCC Group, a nonprofit consultancy headquartered in New York, New York. They should also look at whether organizations have the systems in place to sustain their missions and continue to thrive. An expert on nonprofit organizational management, York has spent years studying sustainable charitable organizations. He defines them as nonprofits that are able to achieve the ongoing financial support to stay relevant and continue doing core mission work. In his analysis of well over 2,500 larger nonprofits, York has found that many are not sustaining, and are actually scaling back in size. “One of the biggest challenges of nonprofit sustainability is the general public’s perception that every dollar donated has to go only to the delivery of service,” says York. “What our data shows is that there are some fundamental capacities that have to be there in order for organizations to sustain and grow.” York’s research highlights the importance of data-driven leadership at successful nonprofits. “You’ve got to have the tools, the systems, and the technologies to get objective information on what you do, the people you serve, and the results you’re achieving,” says York. “If leaders don’t have the knowledge and the data, they can’t make the strategic decisions about programs to take organizations to the next level.” Historically, AmeriCares associates have used time-tested and cost-effective strategies to ship and then track supplies from donation to delivery to their destinations in designated time frames. When disaster strikes, AmeriCares ships by air and generally pulls out all the stops to deliver the most urgently needed aid within the first few days and weeks. Then, as situations stabilize, AmeriCares turns to delivering sea containers for the postemergency and ongoing aid so often needed over the long term. According to McDermott, getting a shipment out the door is fairly complicated, requiring as many as five different AmeriCares teams collaborating together. The entire process can take months—from when products are received in the warehouse and deciding which recipients to allocate supplies to, to getting customs and governmental approvals in place, actually shipping products, and finally ensuring that the products are received in-country. Delivering that aid is no small affair. “Our volume exceeds half a billion dollars a year worth of donated medicines and medical supplies, so it’s a sizable logistical operation to bring these products in and get them out to the right place quickly to have the most impact,” says Sears. “We really pride ourselves on our controls and efficiencies.” Adding to that complexity is the fact that the longer it takes to deliver aid, the more dire the human need can be. Any time AmeriCares associates can shave off the complicated aid delivery process can translate into lives saved. “It’s really being able to track information consistently that will help us to see where are the bottlenecks and where can we work on improving our processes,” says McDermott. Setting a Standard Productivity and information management improvements were key objectives for AmeriCares when staff began the process of implementing Oracle’s Primavera solution. But before configuring the software, the staff needed to take the time to analyze the systems already in place. According to Greg Loop, manager of database systems at AmeriCares, the organization received guidance from several consultants, including Rich D’Addario, consulting project manager in the Primavera Global Business Unit at Oracle, who was instrumental in shepherding the critical requirements-gathering phase. D’Addario encouraged staff to begin documenting shipping processes by considering the order in which activities occur and which ones are dependent on others to get accomplished. This exercise helped everyone realize that to be more efficient, they needed to keep track of shipments in a more standard way. “The staff didn’t recognize formal project management methodology,” says D’Addario. “But they did understand what the most important things are and that if they go wrong, an entire project can go off course.” Before, if a boatload of supplies was being sent to Haiti and there was a problem somewhere, a lot of time was taken up finding out where the problem was—because staff was not tracking things in a standard way. As a result, even more time was needed to find possible solutions to the problem and alert recipients that the aid might be delayed. “For everyone to put on the project manager hat and standardize the way every single thing is done means that now the whole organization is on the same page as to what needs to occur from the time a hurricane hits Haiti and when a boat pulls in to unload supplies,” says D’Addario. With so much care taken to put a process foundation firmly in place, configuring the Primavera solution was actually quite simple. Specific templates were set up for different types of shipments, and dashboards were implemented to provide executives with clear overviews of every project in the system. AmeriCares’ Loop reports that system planning, refining, and testing, followed by writing up documentation and training, took approximately four months. The system went live in spring 2011 at AmeriCares’ Connecticut headquarters. While the nonprofit has an international presence, with warehouses in Europe and offices in Haiti, India, Japan, and Sri Lanka, most donated medicines come from U.S. entities and are shipped from the U.S. out to the rest of the world. In addition, all shipments are tracked from the U.S. office. AmeriCares doesn’t expect the Primavera system to take months off the shipping time, especially for sea containers. However, any time saved is still important because it will allow aid to be delivered to people more quickly at a lower overall cost. “If we can trim a day or two here or there, that can translate into lives that we’re saving, especially in emergency situations,” says Sears. A Cultural Change Beyond the measurable benefits that come with IT-driven process improvement, AmeriCares management is seeing a change in culture as a result of the Primavera project. One change has been treating every shipment of aid as a project, and everyone involved with facilitating shipments as a project manager. “This is a revolutionary concept for us,” says McDermott. “Before, we were used to thinking we were doing logistics—getting a container from point A to point B without looking at it as one project and really understanding what it meant to manage it.” AmeriCares staff is also happy to report that collaboration within the organization is much more efficient. When someone creates a shipment in the Primavera system, the same shared template is used, which means anyone can log in to the system to see the status of a shipment. Knowledgeable staff can access a shipment project to help troubleshoot a problem. Management can easily check the status of projects across the organization. “Dashboards are really useful,” says McDermott. “Instead of going into the details of each project, you can just see the high-level real-time information at a glance.” The new system is helping team members focus on proactively managing shipments rather than simply reacting when problems occur. For example, when a container is shipped, documents must be included for customs clearance. Now, the shipping template has built-in reminders to prompt team members to ask for copies of these documents from freight forwarders and to follow up with partners to discover if a shipment is on time. In the past, staff may not have worked on securing these documents until they’d been notified a shipment had arrived in-country. Another benefit of capturing and adopting best practices within the Primavera system is that staff training is easier. “Capturing the processes in documented steps and milestones allows us to teach new staff members how to do their jobs faster,” says Sears. “It provides them with the knowledge of their predecessors so they don’t have to keep reinventing the wheel.” With the Primavera system already generating positive results, management is eager to take advantage of advanced capabilities. Loop is working on integrating the company’s proprietary inventory management system with the Primavera system so that when logistics or warehousing operators input data, the information will automatically go into the Primavera system. In the past, this information had to be manually keyed into spreadsheets, often leading to errors. Mining Historical Data Another feature on the horizon for AmeriCares is utilizing Primavera P6 Professional Project Management reporting capabilities. As the system begins to include more historical data, management soon will be able to draw on this information to conduct analysis that has not been possible before and create customized reports. For example, at the beginning of the shipment process, staff will be able to use historical data to more accurately estimate how long the approval process should take for a particular country. This could help ensure that food and medicine with limited shelf lives do not get stuck in customs or used beyond their expiration dates. The historical data in the Primavera system will also help AmeriCares with better planning year to year. The nonprofit’s staff has always put together a plan at the beginning of the year, but this has been very challenging simply because it is impossible to predict disasters. Now, management will be able to look at historical data and see trends and statistics as they set current objectives and prepare for future need. In addition, this historical data will provide AmeriCares management with the ability to review year-end data and compare actual project results with goals set at the beginning of the year—to see if desired outcomes were achieved and if there are areas that need improvement. It’s this type of information that is so valuable to donors. And, according to York, project management software can play a critical role in generating the data to help nonprofits sustain and grow. “It is important to invest in systems to help replicate, expand, and deliver services,” says York. “Project management software can help because it encourages nonprofits to examine program or service changes and how to manage moving forward.” Sears believes that AmeriCares donors will support the return on investment the organization will achieve with the Primavera solution. “It won’t be financial returns, but rather how many more people we can help for a given dollar or how much more quickly we can respond to a need,” says Sears. “I think donors are receptive to such arguments.” And for AmeriCares, it is all about the future and increasing results. The project management environment currently may be quite simple, but IT staff plans to expand the complexity and functionality as the organization grows in its knowledge of project management and the goals it wants to achieve. “As we use the system over time, we’ll continue to refine our best practices and accumulate more data,” says Sears. “It will advance our ability to make better data-driven decisions.”

Enabling DNS for IPv6 infrastructure

After successful automatic distribution of IPv6 address information via DHCPv6 in your local network it might be time to start offering some more services. Usually, we would use host names in order to communicate with other machines instead of their bare IPv6 addresses. During the following paragraphs we are going to enable our own DNS name server with IPv6 address resolving. This is the third article in a series on IPv6 configuration: Configure IPv6 on your Linux system DHCPv6: Provide IPv6 information in your local network Enabling DNS for IPv6 infrastructure Accessing your web server via IPv6 Piece of advice: This is based on my findings on the internet while reading other people's helpful articles and going through a couple of man-pages on my local system. What's your name and your IPv6 address? $ sudo service bind9 status * bind9 is running If the service is not recognised, you have to install it first on your system. This is done very easy and quickly like so: $ sudo apt-get install bind9 Once again, there is no specialised package for IPv6. Just the regular application is good to go. But of course, it is necessary to enable IPv6 binding in the options. Let's fire up a text editor and modify the configuration file. $ sudo nano /etc/bind/named.conf.optionsacl iosnet { 127.0.0.1; 192.168.1.0/24; ::1/128; 2001:db8:bad:a55::/64;};listen-on { iosnet; };listen-on-v6 { any; };allow-query { iosnet; };allow-transfer { iosnet; }; Most important directive is the listen-on-v6. This will enable your named to bind to your IPv6 addresses specified on your system. Easiest is to specify any as value, and named will bind to all available IPv6 addresses during start. More details and explanations are found in the man-pages of named.conf. Save the file and restart the named service. As usual, check your log files and correct your configuration in case of any logged error messages. Using the netstat command you can validate whether the service is running and to which IP and IPv6 addresses it is bound to, like so: $ sudo service bind9 restart $ sudo netstat -lnptu | grep "named\W*$"tcp 0 0 192.168.1.2:53 0.0.0.0:* LISTEN 1734/named tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 1734/named tcp6 0 0 :::53 :::* LISTEN 1734/named udp 0 0 192.168.1.2:53 0.0.0.0:* 1734/named udp 0 0 127.0.0.1:53 0.0.0.0:* 1734/named udp6 0 0 :::53 :::* 1734/named Sweet! Okay, now it's about time to resolve host names and their assigned IPv6 addresses using our own DNS name server. $ host -t aaaa www.6bone.net 2001:db8:bad:a55::2Using domain server:Name: 2001:db8:bad:a55::2Address: 2001:db8:bad:a55::2#53Aliases: www.6bone.net is an alias for 6bone.net.6bone.net has IPv6 address 2001:5c0:1000:10::2 Alright, our newly configured BIND named is fully operational. Eventually, you might be more familiar with the dig command. Here is the same kind of IPv6 host name resolve but it will provide more details about that particular host as well as the domain in general. $ dig @2001:db8:bad:a55::2 www.6bone.net. AAAA More details on the Berkeley Internet Name Domain (bind) daemon and IPv6 are available in Chapter 22.1 of Peter Bieringer's HOWTO on IPv6. Setting up your own DNS zone Now, that we have an operational named in place, it's about time to implement and configure our own host names and IPv6 address resolving. The general approach is to create your own zone database below the bind folder and to add AAAA records for your hosts. In order to achieve this, we have to define the zone first in the configuration file named.conf.local. $ sudo nano /etc/bind/named.conf.local //// Do any local configuration here//zone "ios.mu" { type master; file "/etc/bind/zones/db.ios.mu";}; Here we specify the location of our zone database file. Next, we are going to create it and add our host names, our IP and our IPv6 addresses. $ sudo nano /etc/bind/zones/db.ios.mu $ORIGIN .$TTL 259200 ; 3 daysios.mu IN SOA ios.mu. hostmaster.ios.mu. ( 2014031101 ; serial 28800 ; refresh (8 hours) 7200 ; retry (2 hours) 604800 ; expire (1 week) 86400 ; minimum (1 day) ) NS server.ios.mu.$ORIGIN ios.mu.server A 192.168.1.2server AAAA 2001:db8:bad:a55::2client1 A 192.168.1.3client1 AAAA 2001:db8:bad:a55::3client2 A 192.168.1.4client2 AAAA 2001:db8:bad:a55::4 With a couple of machines in place, it's time to reload that new configuration. Note: Each time you are going to change your zone databases you have to modify the serial information, too. Named loads the plain text zone definitions and converts them into an internal, indexed binary format to improve lookup performance. If you forget to change your serial then named will not use the new records from the text file but the indexed ones. Or you have to flush the index and force a reload of the zone. This can be done easily by either restarting the named: $ sudo service bind9 restart or by reloading the configuration file using the name server control utility - rndc: $ sudo rndc reconfig Check your log files for any error messages and whether the new zone database has been accepted. Next, we are going to resolve a host name trying to get its IPv6 address like so: $ host -t aaaa server.ios.mu. 2001:db8:bad:a55::2Using domain server:Name: 2001:db8:bad:a55::2Address: 2001:db8:bad:a55::2#53Aliases: server.ios.mu has IPv6 address 2001:db8:bad:a55::2 Looks good. Alternatively, you could have just ping'd the system as well using the ping6 command instead of the regular ping: $ ping6 serverPING server(2001:db8:bad:a55::2) 56 data bytes64 bytes from 2001:db8:bad:a55::2: icmp_seq=1 ttl=64 time=0.615 ms64 bytes from 2001:db8:bad:a55::2: icmp_seq=2 ttl=64 time=0.407 ms^C--- ios1 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1001msrtt min/avg/max/mdev = 0.407/0.511/0.615/0.104 ms That also looks promising to me. How about your configuration? Next, it might be interesting to extend the range of available services on the network. One essential service would be to have web sites at hand.

Memory leak involving jQuery Ajax requests

- by Eli Courtwright

I have a webpage that's leaking memory in both IE8 and Firefox; the memory usage displayed in the Windows Process Explorer just keeps growing over time. The following page requests the "unplanned.json" url, which is a static file that never changes (though I do set my Cache-control HTTP header to no-cache to make sure that the Ajax request always goes through). When it gets the results, it clears out an HTML table, loops over the json array it got back from the server, and dynamically adds a row to an HTML table for each entry in the array. Then it waits 2 seconds and repeats this process. Here's the entire webpage: <html> <head> <title>Test Page</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> </head> <body> <script type="text/javascript"> function kickoff() { $.getJSON("unplanned.json", resetTable); } function resetTable(rows) { $("#content tbody").empty(); for(var i=0; i<rows.length; i++) { $("<tr>" + "<td>" + rows[i].mpe_name + "</td>" + "<td>" + rows[i].bin + "</td>" + "<td>" + rows[i].request_time + "</td>" + "<td>" + rows[i].filtered_delta + "</td>" + "<td>" + rows[i].failed_delta + "</td>" + "</tr>").appendTo("#content tbody"); } setTimeout(kickoff, 2000); } $(kickoff); </script> <table id="content" border="1" style="width:100% ; text-align:center"> <thead><tr> <th>MPE</th> <th>Bin</th> <th>When</th> <th>Filtered</th> <th>Failed</th> </tr></thead> <tbody></tbody> </table> </body> </html> If it helps, here's an example of the json I'm sending back (it's this exact array wuith thousands of entries instead of just one): [ { mpe_name: "DBOSS-995", request_time: "09/18/2009 11:51:06", bin: 4, filtered_delta: 1, failed_delta: 1 } ] EDIT: I've accepted Toran's extremely helpful answer, but I feel I should post some additional code, since his removefromdom jQuery plugin has some limitations: It only removes individual elements. So you can't give it a query like `$("#content tbody tr")` and expect it to remove all of the elements you've specified. Any element that you remove with it must have an `id` attribute. So if I want to remove my `tbody`, then I must assign an `id` to my `tbody` tag or else it will give an error. It removes the element itself and all of its descendants, so if you simply want to empty that element then you'll have to re-create it afterwards (or modify the plugin to empty instead of remove). So here's my page above modified to use Toran's plugin. For the sake of simplicity I didn't apply any of the general performance advice offered by Peter. Here's the page which now no longer memory leaks: <html> <head> <title>Test Page</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> </head> <body> <script type="text/javascript">  </script> <div id="message" style="color:red"></div> <table id="content" border="1" style="width:100% ; text-align:center"> <thead><tr> <th>MPE</th> <th>Bin</th> <th>When</th> <th>Filtered</th> <th>Failed</th> </tr></thead> <tbody id="id_field_required"></tbody> </table> </body> </html> FURTHER EDIT: I'll leave my question unchanged, though it's worth noting that this memory leak has nothing to do with Ajax. In fact, the following code would memory leak just the same and be just as easily solved with Toran's removefromdom jQuery plugin: function resetTable() { $("#content tbody").empty(); for(var i=0; i<1000; i++) { $("#content tbody").append("<tr><td>" + "DBOSS-095" + "</td>" + "<td>" + 4 + "</td>" + "<td>" + "09/18/2009 11:51:06" + "</td>" + "<td>" + 1 + "</td>" + "<td>" + 1 + "</td></tr>"); } setTimeout(resetTable, 2000); } $(resetTable);

I started RoR development a few months ago, and being new to Mac... Time flies and now I have a lot different ruby versions, rails versions and gems versions located everywhere......And currently I installed rvm and things got even worst, all things messed! And so I started want to clean all things and use rvm again! I want to uninstall all gems, all rails, and all ruby versions, except the system's default one (the very old one born with the mac). Or any other better solutions or suggestions!?

Reading input from a text file, omits the first and adds a nonsense value to the end?

- by Greenhouse Gases

Hi there When I input locations from a txt file I am getting a peculiar error where it seems to miss off the first entry, yet add a garbage entry to the end of the link list (it is designed to take the name, latitude and longitude for each location you will notice). I imagine this to be an issue with where it starts collecting the inputs and where it stops but I cant find the error!! It reads the first line correctly but then skips to the next before adding it because during testing for the bug it had no record of the first location Lisbon though whilst stepping into the method call it was reading it. Very bizarre but hopefully someone knows the issue. Here is firstly my header file: #include <string> struct locationNode { char nodeCityName [35]; double nodeLati; double nodeLongi; locationNode* Next; void CorrectCase() // Correct upper and lower case letters of input { int MAX_SIZE = 35; int firstLetVal = this->nodeCityName[0], letVal; int n = 1; // variable for name index from second letter onwards if((this->nodeCityName[0] >90) && (this->nodeCityName[0] < 123)) // First letter is lower case { firstLetVal = firstLetVal - 32; // Capitalise first letter this->nodeCityName[0] = firstLetVal; } while(n <= MAX_SIZE - 1) { if((this->nodeCityName[n] >= 65) && (this->nodeCityName[n] <= 90)) { letVal = this->nodeCityName[n] + 32; this->nodeCityName[n] = letVal; } n++; } //cityNameInput = this->nodeCityName; } }; class Locations { private: int size; public: Locations(){ }; // constructor for the class locationNode* Head; //int Add(locationNode* Item); }; And here is the file containing main: // U08221.cpp : main project file. #include "stdafx.h" #include "Locations.h" #include <iostream> #include <string> #include <fstream> using namespace std; int n = 0,x, locationCount = 0, MAX_SIZE = 35; string cityNameInput; char targetCity[35]; bool acceptedInput = false, userInputReq = true, match = false, nodeExists = false;// note: addLocation(), set to true to enable user input as opposed to txt file locationNode *start_ptr = NULL; // pointer to first entry in the list locationNode *temp, *temp2; // Part is a pointer to a new locationNode we can assign changing value followed by a call to Add locationNode *seek, *bridge; void setElementsNull(char cityParam[]) { int y=0, count =0; while(cityParam[y] != NULL) { y++; } while(y < MAX_SIZE) { cityParam[y] = NULL; y++; } } void addLocation() { temp = new locationNode; // declare the space for a pointer item and assign a temporary pointer to it if(!userInputReq) // bool that determines whether user input is required in adding the node to the list { cout << endl << "Enter the name of the location: "; cin >> temp->nodeCityName; temp->CorrectCase(); setElementsNull(temp->nodeCityName); cout << endl << "Please enter the latitude value for this location: "; cin >> temp->nodeLati; cout << endl << "Please enter the longitude value for this location: "; cin >> temp->nodeLongi; cout << endl; } temp->Next = NULL; //set to NULL as when one is added it is currently the last in the list and so can not point to the next if(start_ptr == NULL){ // if list is currently empty, start_ptr will point to this node start_ptr = temp; } else { temp2 = start_ptr; // We know this is not NULL - list not empty! while (temp2->Next != NULL) { temp2 = temp2->Next; // Move to next link in chain until reach end of list } temp2->Next = temp; } ++locationCount; // increment counter for number of records in list if(!userInputReq){ cout << "Location sucessfully added to the database!

Any ideas why? Thank you in advance.
