  • Delaying emails in PHP to avoid exceeding server limit

    - by Andrew P.
    Okay, so here's my problem: I have a list of members on a website, and periodically one of the admins my site (who are not very web or tech savvy) will send a newsletter to the memberlist. My current memberlist is well over 800 individuals long. So, I wrote an email script that sends the email to the full memberlist, with the members listed in the Bcc header. However, I've discovered that my host server has a limit of 300 emails per hour, which I apparently exceed even though the members are listed in the Bcc field. (I wasn't previously aware that the behaviour of Bcc was to send separate emails for each name on the list...) After some thought, I've come to the conclusion that my only solution is to have my script send only the email to only the first 300 emails, wait an hour, and send a second email to the next three hundred, wait another hour, and so on until I've sent the email to the whole member list. Looking around on the internet, I've seen some other solutions people have come up with for delaying emails in PHP. Sleep() is obviously not an option, because I can't just leave the script open and running for 3 or four hours. I've seen some people suggest cron jobs, but I'm not sure how feasible it would be to create three new cron jobs every time I send an email, use them once, and then delete them afterward. The final (and what I think is the smartest) solution I've seen, is to have a table in my database to temporarily store the emails to be delayed and sent later, and then create a cron job that checks this sql table every hour or so, compares the timestamp of the row to the current timestamp, and then sends the email if an hour has passed. So I'm asking you all which method you would recommend. Is there an easier solution that I've completely looked over (aside from getting a different hosting plan. ha!), or is there a cleaner way to do it than the database / cron job approach? tl;dr: I have 800 emails to send in an hour on a server that limits me to 300/hr. Using PHP, find a way to get around this problem in a way that the person sending the email needs only to click "send."

  • Unpacking an assembly inside of a war

    - by Walter White
    Hi all, I have another project which contains static content (css, images, JS, etc.), and I need that to be copied to the web root directory of jetty for testing. In that project, I output a zip file packaging up all of the images, CSS, etc. I have several of those virtualhost projects for different clients and my question is, how do I unpack the zip file that was already installed into the maven repository to the jetty web root?

  • Robust Javascript parser in Java

    - by Misha Koshelev
    Dear All: I am looking for a robust Javascript parser written in Java - by which I mean a Javascript parser that is able to handle most real world Javascript. I am only interested in parsing Javascript, not in executing it. I have found Rhino: http://groups.google.com/group/mozilla.dev.tech.js-engine.rhino/browse_thread/thread/1eff23a8ee57b991 Am I missing anything? Is this the best solution? Thank you! Misha

  • JQuery templating engines

    - by Maurice
    I am looking for a template engine to use client side. I have been trying a few like jsRepeater and jQuery Templates. While they seem to work OK in FireFox they all seem to break down in IE7 when it comes down to rendering HTML tables. I also took a look at MicrosoftAjaxTemplates.js (from http://www.codeplex.com/aspnet/Release/ProjectReleases.aspx?ReleaseId=16766) but turns out that has the same problem. Any advice on other templating engines to use?

  • Working with anonymous modules in Ruby

    - by Byron Park
    Suppose I make a module as follows: m = Module.new do class C end end Three questions: Other than a reference to m, is there a way I can access C and other things inside m? Can I give a name to the anonymous module after I've created it (just as if I'd typed "module ...")? How do I delete the anonymous module when I'm done with it, such that the constants it defines are no longer present?

  • Programming graphics and sound on PC - Total newbie questions, and lots of them!

    - by Russel
    Hello, This isn't exactly specifically a programming question (or is it?) but I was wondering: How are graphics and sound processed from code and output by the PC? My guess for graphics: There is some reserved memory space somewhere that holds exactly enough room for a frame of graphics output for your monitor. IE: 800 x 600, 24 bit color mode == 800x600x3 = ~1.4MB memory space Between each refresh, the program writes video data to this space. This action is completed before the monitor refresh. Assume a simple 2D game: the graphics data is stored in machine code as many bytes representing color values. Depending on what the program(s) being run instruct the PC, the processor reads the appropriate data and writes it to the memory space. When it is time for the monitor to refresh, it reads from each memory space byte-for-byte and activates hardware depending on those values for each color element of each pixel. All of this of course happens crazy-fast, and repeats x times a second, x being the monitor's refresh rate. I've simplified my own likely-incorrect explanation by avoiding talk of double buffering, etc Here are my questions: a) How close is the above guess (the three steps)? b) How could one incorporate graphics in pure C++ code? I assume the practical thing that everyone does is use a graphics library (SDL, OpenGL, etc), but, for example, how do these libraries accomplish what they do? Would manual inclusion of graphics in pure C++ code (say, a 2D spite) involve creating a two-dimensional array of bit values (or three dimensional to include multiple RGB values per pixel)? Is this how it would be done waaay back in the day? c) Also, continuing from above, do libraries such as SDL etc that use bitmaps actual just build the bitmap/etc files into machine code of the executable and use them as though they were build in the same matter mentioned in question b above? d) In my hypothetical step 3 above, is there any registers involved? Like, could you write some byte value to some register to output a single color of one byte on the screen? Or is it purely dedicated memory space (=RAM) + hardware interaction? e) Finally, how is all of this done for sound? (I have no idea :) )

  • How can a 1Gb Java heap on a 64bit machine use 3Gb of VIRT space?

    - by Graeme Moss
    I run the same process on a 32bit machine as on a 64bit machine with the same memory VM settings (-Xms1024m -Xmx1024m) and similar VM version (1.6.0_05 vs 1.6.0_16). However the virtual space used by the 64bit machine (as shown in top under "VIRT") is almost three times as big as that in 32bit! I know 64bit VMs will use a little more memory for the larger references, but how can it be three times as big? Am I reading VIRT in top incorrectly? Full data shown below, showing top and then the result of jmap -heap, first for 64bit, then for 32bit.

  • Difference between arguments in setInterval calls

    - by Martin Janiczek
    What's the difference between these setInterval calls and which ones should be used? setInterval("myFunction()",1000) setInterval("myFunction",1000) setInterval(myFunction(),1000) setInterval(myFunction,1000) My guess is that JS uses eval() on the first two (strings) and calls the latter two directly. Also, I don't understand the difference between the calls with and without parentheses. The ones with parentheses call it directly and then periodically call its return value?

  • How can I refactor out needing so many for-loops in rails?

    - by Angela
    I need help refactoring this multi-loop thing. Here is what I have: Campaign has_many Contacts Campaign also has many templates for EVent (Email, Call, and Letter). I need a list of all the Emails, Calls and Letters that are "overdue" for every Contact that belongs to a Campaign. Overdue is determined by a from_today method which looks at the date the Contact was entered in the system and the number of days that needs to pass for any given Event. from_today() outputs the number of days from today that the Event should be done for a given Contact. Here is what I've done, it works for all Emails in a Campaign across all contacts. I was going to try to create another each do loop to change the class names. Wasn't sure where to begin: named_scope, push some things into a method, etcetera, or -- minimum to be able to dynamically change the class names so at least it loops three timees across the different events rather than repeating the code three times: <% @campaigns.each do |campaign| %> <h2><%= link_to campaign.name, campaign %></h2> <% @events.each do |event| %> <%= event %> <% for email in campaign.emails %> <h4><%= link_to email.title, email %> <%= email.days %> days</h4> <% for contact in campaign.contacts.find(:all, :order => "date_entered ASC" ) %> <% if (from_today(contact, email.days) < 0) %> <% if show_status(contact, email) == 'no status'%> <p> <%= full_name(contact) %> is <%= from_today(contact,email.days).abs%> days overdue: <%= do_event(contact, email) %> </p> <% end %> <% end %> <% end %> <% end %> <% end %> <% end %>

  • Removing the transparency from image while keeping the actual image

    - by KPL
    Hello people, I have three images,and , they are not square or rectangular in shape. They are just like face of anyone. So, basically, my images are in the size 196x196 or anything like that, but complete square or rectangle with the face in the middle and transperant background in the rest of the portion. Now, I want to remove the transperant background too and just keep the faces. Don't know if this is possible and mind you, this isn't a programming question.

  • Optimizing jQuery for Tabs

    - by jpdbaugh
    I am in the process of developing a widget. The widget has three tabs that are implemented in the following way. <div id="widget"> <ul id="tabs"> <li><a href="http...">One</a></li> <li><a href="http...">Two</a></li> <li><a href="http...">Three</a></li> </ul> <div id="tab_container"> <div id="tab_content"> //Tab Content goes here... </div> </div> </div> // The active class is initialized when the document loads $("#tabs li a").click(function() { $("#tabs li.active").removeClass("active"); $("#tab_content").load($(this).attr('href')); $(this).parent().addClass("active"); return false; }); The problem I am having is that the jquery code that have written is very slow. If the user changes tabs quickly the widget gets behing and bogged down. This causes the tabs to to not align with the data being displayed and just general lag. I believe that this is because the tab is being changed before $.load() is finished. I have tried to implement the following: ("#tabs li a").click(function() { $("#tabs li.active").removeClass("active"); $("#tab_content").load($(this).attr('href'), function (){ $(this).parent().addClass("active"); }); return false; }); It is my understanding that the callback function within in the load function does not execute until the load function is completed. I think this would solve my problem, however I can not come up with a way to select the correct tab that was clicked within the callback function. If this is not the way to do this then what is the best way implement these tabs so that they would stop loading an old request and load the newest tab selection by the user? Thanks

  • How to create an "endless" scrolling slideshow?

    - by Andrew
    I know a good bit of JS and I'm familiar with jQuery, and I'm trying to create an "endless" slideshow (like the one on http://thisismedium.com/), where the images scroll -- one right behind the other -- and when it reaches the end it loops. I don't really know how to start, so I was hoping someone could point me in the right direction. I created a slideshow before that automatically switched images and let you click Next and Previous, but I'm stuck here. =/.

  • JSF 2.0 Problem

    - by Sarang
    I am doing a project where I am using JSF 2.0 & Primefaces UI Components. There is a tab view component with tabs, "Day","Week" & "Month". In all tab, I have to display Bar Charts in each. For the same, I am fetching three list using the following three method. In the following code, UpdateCountHelper is fetching the data from database. So, UpdateCountHelper is taking some time for fetching data. This is code for fetching lists : public List<UpdateCount> getDayUpdateCounts() { if (projectFlag == true) { if (displayFlag == 1) { dayUpdateCounts = UpdateCountHelper.getProjectUpdates(1); } else { dayUpdateCounts = UpdateCountHelper.getProjectUpdates(name, 1); } } else { dayUpdateCounts = UpdateCountHelper.getResourceUpdates(userName, 1); } return dayUpdateCounts; } public List<UpdateCount> getMonthUpdateCounts() { if (projectFlag == true) { if (displayFlag == 1) { monthUpdateCounts = UpdateCountHelper.getProjectUpdates(30); } else { monthUpdateCounts = UpdateCountHelper.getProjectUpdates(name, 30); } } else { monthUpdateCounts = UpdateCountHelper.getResourceUpdates(userName, 30); } return monthUpdateCounts; } public List<UpdateCount> getWeekUpdateCounts() { if (projectFlag == true) { if (displayFlag == 1) { weekUpdateCounts = UpdateCountHelper.getProjectUpdates(7); } else { weekUpdateCounts = UpdateCountHelper.getProjectUpdates(name, 7); } } else { weekUpdateCounts = UpdateCountHelper.getResourceUpdates(userName, 7); } return weekUpdateCounts; } This is code for UI of Bar Chart : <p:panel id="Chart"> <p:tabView dynamic="false" cache="false"> <p:tab title="Day"> <p:panel id="chartDayPanel"> <center> <h:outputText id="projectWiseDayText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Day Update"/> <p:columnChart id="projectWiseDayUpdateChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.dayUpdateCounts}" var="dayWiseUpdate" xfield="#{dayWiseUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Project Wise Current Day Update" value="#{dayWiseUpdate.noUpdates}"/> </p:columnChart> <h:outputText id="resourceWiseDayText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Day Update"/> <p:columnChart id="resourceWiseDayUpdateChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.dayUpdateCounts}" var="dayWiseResourceUpdate" xfield="#{dayWiseResourceUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Resource Wise Current Day Update" value="#{dayWiseResourceUpdate.noUpdates}"/> </p:columnChart> </center> </p:panel> </p:tab> <p:tab title="Week"> <p:panel id="chartWeekPanel"> <center> <h:outputText id="projectWiseWeekText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Week Update"/> <p:columnChart id="projectWiseWeekUpdateChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.weekUpdateCounts}" var="weekWiseUpdate" xfield="#{weekWiseUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Project Wise Current Week Update" value="#{weekWiseUpdate.noUpdates}"/> </p:columnChart> <h:outputText id="resourceWiseWeekText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Week Update"/> <p:columnChart id="resourceWiseWeekUpdateChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.weekUpdateCounts}" var="weekWiseResourceUpdate" xfield="#{weekWiseResourceUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Resource Wise Current Week Update" value="#{weekWiseResourceUpdate.noUpdates}"/> </p:columnChart> </center> </p:panel> </p:tab> <p:tab title="Month"> <p:panel id="chartMonthPanel"> <center> <h:outputText id="projectWiseMonthText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Month Update"/> <p:columnChart id="projectWiseMonthUpdateChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.monthUpdateCounts}" var="monthWiseUpdate" xfield="#{monthWiseUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Project Wise Current Month Update" value="#{monthWiseUpdate.noUpdates}"/> </p:columnChart> <h:outputText id="resourceWiseMonthText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Month Update"/> <p:columnChart id="resourceWiseMonthUpdateChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.monthUpdateCounts}" var="monthWiseResourceUpdate" xfield="#{monthWiseResourceUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Resource Wise Current Month Update" value="#{monthWiseResourceUpdate.noUpdates}"/> </p:columnChart> </center> </p:panel> </p:tab> </p:tabView> </p:panel> Now, I have to display same data in other tabview with same tabs as mentioned above & only thing is now I have to display in Pie Chart. Now in pie chart, I am using the same lists. So, it will again fetch the data from database & waste time. To solve that problem I have created other three lists & have given only reference of those previous lists. So, now no database fetching occur. The Code for applying the reference is : public List<UpdateCount> getPieDayUpdateCounts() { pieDayUpdateCounts = dayUpdateCounts; return pieDayUpdateCounts; } public List<UpdateCount> getPieMonthUpdateCounts() { pieMonthUpdateCounts = monthUpdateCounts; return pieMonthUpdateCounts; } public List<UpdateCount> getPieWeekUpdateCounts() { pieWeekUpdateCounts = weekUpdateCounts; return pieWeekUpdateCounts; } But, over here the problem occurring is that only chart of which the tab is enable is displayed but the other remaining 2 tabs are not showing any chart. The code for UI is : <p:tabView dynamic="false" cache="false"> <p:tab title="Day"> <center> <p:panel id="pieChartDayPanel"> <h:outputText id="projectWiseDayPieChartText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Day Update"/> <p:pieChart id="projectWiseDayUpdatePieChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.dayUpdateCounts}" var="dayWisePieUpdate" categoryField="#{dayWisePieUpdate.name}" dataField="#{dayWisePieUpdate.noUpdates}" height="200" width="200"/> <h:outputText id="resourceWiseDayPieChartText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Day Update"/> <p:pieChart id="resourceWiseDayUpdatePieChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.dayUpdateCounts}" var="dayWiseResourcePieUpdate" categoryField="#{dayWiseResourcePieUpdate.name}" dataField="#{dayWiseResourcePieUpdate.noUpdates}" height="200" width="200"/> </p:panel> </center> </p:tab> <p:tab title="Week"> <center> <p:panel id="pieChartWeekPanel"> <h:outputText id="projectWiseWeekPieChartText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Week Update"/> <p:pieChart id="projectWiseWeekUpdatePieChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.weekUpdateCounts}" var="weekWisePieUpdate" categoryField="#{weekWisePieUpdate.name}" dataField="#{weekWisePieUpdate.noUpdates}" height="200" width="200"/> <h:outputText id="resourceWiseWeekPieChartText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Week Update"/> <p:pieChart id="resourceWiseWeekUpdatePieChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.weekUpdateCounts}" var="weekWiseResourcePieUpdate" categoryField="#{weekWiseResourcePieUpdate.name}" dataField="#{weekWiseResourcePieUpdate.noUpdates}" height="200" width="200"/> </p:panel> </center> </p:tab> <p:tab title="Month"> <center> <p:panel id="pieChartMonthPanel"> <h:outputText id="projectWiseMonthPieChartText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Month Update"/> <p:pieChart id="projectWiseMonthUpdatePieChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.monthUpdateCounts}" var="monthWisePieUpdate" categoryField="#{monthWisePieUpdate.name}" dataField="#{monthWisePieUpdate.noUpdates}" height="200" width="200"/> <h:outputText id="resourceWiseMonthPieChartText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Month Update"/> <p:pieChart id="resourceWiseMonthUpdatePieChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.monthUpdateCounts}" var="monthWiseResourcePieUpdate" categoryField="#{monthWiseResourcePieUpdate.name}" dataField="#{monthWiseResourcePieUpdate.noUpdates}" height="200" width="200"/> </p:panel> </center> </p:tab> </p:tabView> What should be the reason behind this ?

  • set equal height on multiple divs

    - by Greenie
    I need to set equal height on a series of divs inside another div wrapper. The problem is that I dont want the same height on all of them. The page kind of have 3 columns and the floating divs can be 1, 2 or 3 columns wide. The divs float left, so the following example will give me three rows of divs in my wrapper. How can I set equal height on the divs that are in the same row? In my example I want nr 1 and 2 to have equal height and 3, 4 and 5 another equal height? I cant know beforehand how many divs there is or how wide or high they are. Edit: They can be for instance 300, 600 or 900 px wide and the page width is 900px <div id="wrapper"> <div class="one-wide">nr1</div> <div class="two-wide">nr2</div> <div class="one-wide">nr3</div> <div class="one-wide">nr4</div> <div class="one-wide">nr5</div> <div class="three-wide">nr6</div> </div> Im thinking I somehow need to figure out when the added width of the divs is at the full page width and set equal height on those. Then do the same on the next divs. But I cant wrap my head around it. Currently im just using this to set the height on the children of the wrapper: $.fn.equalHeights = function(px) { $(this).each(function(){ var currentTallest = 0; $(this).children().each(function(i){ if ($(this).height() > currentTallest) { currentTallest = $(this).height(); } }); // for ie6, set height since min-height isn't supported if ($.browser.msie && $.browser.version == 6.0) { $(this).children().css({'height': currentTallest}); } $(this).children('div').css({'min-height': currentTallest}); }); return this; };
