  • Notification Email Best Practices--From Server Setup to Programming

    - by Andrew Wagner
    All, I'm in the process now of building a SaaS tool that allows network admins to generate notification emails to the members of the end-users of our platform (among many many other things). I'm running into a bit of an "out of my expertise" wall, as I know there are a lot of variables involved with configuring an application that can: Run in a distributed way via load balancing and still-- Leverage a single mail server for sending notification emails Process unsubscribe requests Avoid any ISP blacklisting in the process. If anyone has the time and has done this before, I'd love if you could walk me through the A-Z of best practices both from a configuration perspective and an execution perspective for generating these emails (anything from necessary DNS settings to ideal SMTP setup and configuration) Currently, our application generates email via Google Apps using the PHPMailer class. While this works well, it doesn't queue messages (potential for timeout problems if any of our clients amass a very large list of end-users), and Google limits the amount of allowed generated email messages to 500/day. I know this is a lofty question, but any guidance you could provide would be smashing and a big help as we work through this hurtle in our beta development stage. Thanks!

    My app has to load an image from a http server and displaying it into an UIImageView How can i do that?? I tried this: NSString *temp = [NSString alloc]; [temp stringwithString:@"http://192.168.1.2x0/pic/LC.jpg"] temp=[(NSString *)CFURLCreateStringByAddingPercentEscapes( nil, (CFStringRef)temp, NULL, NULL, kCFStringEncodingUTF8) autorelease]; NSData *dato = [NSData alloc]; dato=[NSData dataWithContentsOfURL:[NSURL URLWithString:temp]]; pic = [pic initWithImage:[UIImage imageWithData:dato]]; This code is in viewdidload of the view but nothing is displayed! The server is working because i can load xml files from it. but i can't display that image! I need to load the image programmatically because it has to change depending on the parameter passed! Thank you in advance. Antonio

  • Cygwin socket & thread & other programming issues (some question about Cygwin)

    - by SjB
    I have some question about cygwin : Can I use Cygwin develop socket based code? Does Cygwin have read() and write() functions that work with file descriptors? Can I use Pthread library in Cygwin? Does code that compiles in Cygwin also compile in Linux without any change or with little change? Will an executable file that built by Cygwin run in Linux ? Why does Cygwin not need the linker option -lpthread when I use pthread library? why in #include <iostream> don't I need to use using namespace std; ? Can I work with QT in Cygwin? If so, How?

  • Need help in filtering the data with various condition and filling in scroll window GP

    - by Rahul
    Hi all, I am filtering the data and displaying in scroll window. There are many combination to display this data by customer id, customer id and itemnumber, customer id, itemnumber, work and history condition. And from date and To date condition. My query is when I am selecting the customer id and work or history table it should display the corresponding data. Like select * from price history where customerid=’custid’ and name=’Work’. It should display in scroll only these values none other it the same way history condition should work. Work and History are in check box. In my case whatever range I am selecting whether Work and History always loading with entire data, so it’s not filtering properly. My second problem is if I select from date and keep empty to date …in this case all the data should display from selected from date to end of table data. But I am not getting….pls somebody help me here is my entire coding: if empty('Customer Number') then warning "Select Customer ID"; focus 'Customer Number'; abort script; end if; if '(L) RadioGroup4' of window Window1 of form 'Customer Pricing Inquiry'=1 then if empty(Date) then abort script;

  • Android Programming: Stay with CyanogenMod?

    - by Android Eve
    My new Nexus One came pre-installed with CyanogenMod. It's great so far, but since I bought it for software development purposes (initially just learning how to program for Android), should I stay with it, or install the official Android OS? If the latter, 2.2 or 2.3? My main concern is compatibility issues with documented API, that is wasting time on debugging problems that shouldn't have been there in the first place.

  • C Programming - Convert an integer to binary

    - by leo
    Hi guys - i was hopefully after some tips opposed to solutions as this is homework and i want to solve it myself I am firstly very new to C. In fact i have never done any before, though i have previous java experience from modules at university. I am trying to write a programme that converts a single integer in to binary. I am only allowed to use bitwise operations and no library functions Can anyone possibly suggest some ideas about how i would go about doing this. Obviously i dont want code or anything, just some ideas as to what avenues to explore as currenty i am a little confused and have no plan of attack. Well, make that a lot confused :D thanks very much

  • How to automatically remove Flash history/privacy trail? Or stop Flash from storing it?

    - by Arjan van Bentem
    Many people have heard about third-party cookies, and some browsers even block those by default. Some people may even be using Private Browsing modes. However, only few seem to realise that Adobe's Flash player also leaves a cross-browser trail on your local hard drive, and allows for sending cookie-like information back to the server, including third-party sites. And because it is a plugin, Flash does not take any of the browser's privacy settings into account. Sorry for the long post, but first some details about why using Flash raises a privacy concern, followed by the results of my tests: The Flash player keeps a cross-browser history of the domain names of the Flash-sites your computer has visited. Unlike your browser's history, this history is not limited to a certain number of days. History is also recorded while using so-called Private Browsing modes. It is stored on your hard drive (though, as described below, without going to Adobe's site you won't know what is stored). I am not sure if any date and time information is kept about each visit, but to see the domain names: right-click on some Flash content, open the settings dialog, and click the Help icon or click the Advanced button within the Privacy tab. This opens a browser to the help pages on Adobe.com, where one can click through to the Website Storage Settings panel. One can clear the existing list, but one cannot stop it from being recorded again. Flash allows for storing data on your local hard drive, using so-called Local Shared Objects (aka "Flash Cookies"). Just like HTTP cookies, this data can be sent back to the server, for tracking purposes. They are cross-browser, have no expiration date, and no user defined maximum lifetime can be set in the Flash preferences either. These not being HTTP cookies, they are (of course) not blocked by a browser's cookies preferences and are not removed when the normal HTTP cookies are deleted. Adobe has announced that version 10.1 will obey Private Browsing in most popular browsers, but unfortunately no word about also removing the data whenever normal cookies are deleted manually. And its implementation might be confusing: [..] if the browser is in normal browsing mode when the Flash Player instance is created, then that particular instance will forever be in normal browsing mode (private browsing is turned off). Accordingly, toggling private browsing on or off without refreshing the page or closing the private browsing window will not impact Flash Player. Local Shared Objects are not limited to the site you visit, and third-party storage is enabled by default. At the Global Storage Settings panel one can deselect the default Allow third-party Flash content to store data on your computer. Because of the cross-browser and expiration-less nature (and the fact that few people know about it), I feel that the cross-browser third-party Flash Cookies are more dangerous for visitor tracking than third-party normal HTTP cookies. They are even used to restore plain HTTP cookies that the user tried to delete: "All advertisers, websites and networks use cookies for targeted advertising, but cookies are under attack. According to current research they are being erased by 40% of users creating serious problems," says Mookie Tenembaum, founder of United Virtualities. "From simple frequency capping to the more sophisticated behavioral targeting, cookies are an essential part of any online ad campaign. PIE ["Persistent Identification Element"] will give publishers and third-party providers a persistent backup to cookies effectively rendering them unassailable", adds Tenembaum. [..] To justify this tracking mechanism, UV's Tenembaum said, "The user is not proficient enough in technology to know if the cookie is good or bad, or how it works." When selecting None (zero KB) for Specify the amount of disk space that website websites that you haven't yet visited can use to store information on your computer, and checking Never ask again then some sites do not work. However, the same site might work when setting it to None but without selecting Never ask again, and then choose Deny whenever prompted. Both options would result in zero KB of data being allowed, but the behaviour differs. The plugin also provides a Flash Player cache for Adobe-signed files. I guess these files are not an issue. So: how to automatically delete that information? On a Mac, one can find a settings.sol file and a folder for each visited Flash-website in: $HOME/Library/Preferences/Macromedia/Flash Player/macromedia.com/support/flashplayer/sys/ Deleting the settings.sol file and all the folders in sys, removes the trail from the settings panels. However, the actual Local Shared Ojects are elsewhere (see Wikipedia for locations on other operating systems), in a randomly named subfolder of: $HOME/Library/Preferences/Macromedia/Flash Player/#SharedObjects But then: how to remove this automatically? Simply removing the folders and the settings.sol file every now and then (like by using launchd or Windows' Task Scheduler) may interfere with active browsers. Or is it safe to assume that, given the cross-browser nature, the plugin would not care if things are removed while it is active? Only clearing during log-off may not work for those who hibernate all the time. Firefox users can install BetterPrivacy or Objection to delete the Local Shared Objects (for all others browsers as well). I don't know if that also deletes the trail of website domain names. Or: how to stop Flash from storing a history trail? Change of plans: I'm currently testing prohibiting Flash to write to its own sys and #SharedObjects folders. So far, Flash has not tried to restore permissions (though, when deleting the folders, Flash will of course recreate them). I've not encountered any problems but this may take some while to validate, using multiple browsers and sites. I've not yet found a log that reports errors. On a Mac: cd "$HOME/Library/Preferences/Macromedia/Flash Player/macromedia.com/support/flashplayer" rm -r sys/* chmod u-w sys cd "$HOME/Library/Preferences/Macromedia/Flash Player" # preserve the randomly named subfolders (only preserving the latest would suffice; see below) rm -r \#SharedObjects/*/* chmod -R u-w \#SharedObjects I guess the above chmods cannot be achieved on an old Windows system (I'm not sure about XP and Vista?). Though maybe on Windows one could replace the folders sys and #SharedObjects with dummy files with the same names? Anyone? Obviously, keeping Flash from storing those Local Shared Objects for all sites may cause problems. Some test results (Flash 10 on Mac OS X): When blocking the sys folder (even when leaving the #SharedObjects folder writable) then YouTube won't remember your volume settings while viewing multiple videos. Temporarily allowing write access to the blocked folders while visiting trusted sites (to only create folders for domains you like, maybe including references in settings.sol) solves that. This way, for YouTube, Flash could be allowed to write to sys/#s.ytimg.com and #SharedObjects/s.ytimg.com, while Flash could not create new folders for other domains. One may also need to make settings.sol read-only afterwards, or delete it again. When blocking both the sys and #SharedObjects folders, YouTube and Vimeo work fine (though they might not remember any settings). However, Bits on the Run refuses to even show the video player. This is solved by temporarily unblocking the #SharedObjects folder, to allow Flash to create a subfolder with some random name. Within this folder, it would create yet another folder for the current Flash website (content.bitsontherun.com). Removing that website-specific folder, and blocking both #SharedObjects and the randomly named subfolder, still seems to allow Bits on the Run to operate, even though it still cannot write anything to disk. So: the existence of the randomly named subfolder (even when write protected) is important for some sites. When I first found the #SharedObjects folder, it held many subfolders with random names, some created on the very same day. I wonder when Flash decides it wants a new folder, and how it determines (and remembers) that random name. For a moment I considered not blocking write access for sys and #SharedObjects, but explicitly creating read-only folders for well-known third-party tracking domains (like based on a list from, for example, AdBlock Plus). That way, any other domain could still create Local Shared Objects. But the list would be long, and the domains from AdBlock Plus are probably all third-party domains anyway, so disabling Allow third-party Flash content to store data on your computer might have the very same result. Any experience anyone? (Final notes: if the above links to the settings panels do not work in the future, then use the URL that is known to Flash player as a starting point: www.adobe.com/go/settingsmanager. See also "You Deleted Your Cookies? Think Again" at Wired.com -- which uses Flash cookies itself as well... For the very suspicious using Time Machine: you may want to exclude both folders, for each user, and remove the trace that is already on your backup.)

  • Podcast Focusing on XNA or Game/Graphics Programming in General

    - by Daniel Brotherston
    I realize there are a number of podcast related questions, but I'm specifically looking for XNA oriented podcasts. I've Googled around a little bit, but I have been unable to find any current podcasts. I'm just wondering if anyone else knows of any interesting ones. I'd guess if Google can't find them, they don't exist but I thought I'd ask anyways. Also, failing that, podcasts about game development in general would be interesting as well. Thanks!

It appears I am missing a resource according to the debugger, but I'm not sure what. I've tried several different ways of implementing the button. Here is what I have after looking at several posts. import java.util.Random; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; public class MyCharNewChar extends MyCharActivity { private OnClickListener randomButtonListener = new OnClickListener(){ public void onClick(View v) { //Button creates a set of random numbers and updates the values //of the EditText views. Random rand = new Random(); int STR = 1 + rand.nextInt(12); int AGI = 1 + rand.nextInt(12); int DEX = 1 + rand.nextInt(12); int WIS = 1 + rand.nextInt(12); int INT = 1 + rand.nextInt(12); int CON = 1 + rand.nextInt(12); int HP = 1 + rand.nextInt(20); int AC = 1 + rand.nextInt(6); EditText str = (EditText) findViewById(R.id.str); str.setText(STR); EditText agi = (EditText) findViewById(R.id.agi); agi.setText(AGI); EditText dex = (EditText) findViewById(R.id.dex); dex.setText(DEX); EditText wis = (EditText) findViewById(R.id.wis); wis.setText(WIS); EditText intel = (EditText) findViewById(R.id.intel); intel.setText(INT); EditText con = (EditText) findViewById(R.id.con); con.setText(CON); EditText hp = (EditText) findViewById(R.id.baseHP); hp.setText(HP); EditText ac = (EditText) findViewById(R.id.baseAC); ac.setText(AC); } }; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.newchar); Button randomButton = (Button) findViewById(R.id.randomButton); randomButton.setOnClickListener(randomButtonListener); } } Here is the xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout

Still the same error so I must have a problem elsewhere. Any suggestions would be great!

  • More efficient programming than Web.py?

    - by Luke Stanley
    I love webpy, it's really quite Pythonic but I don't like having to add the url mappings and create a class, typically with just 1 function inside it. I'm interested in minimising code typing and prototyping fast. Does anyone have any up and coming suggestions such as Bobo, Bottle, Denied, cherrypy for a lover of webpy's good things? What makes it a good reason? Also I don't mind missing out (strongly) text based templating systems, I use object oriented HTML generation.

  • Which programming languages aren't considered high-level?

    - by hilo
    In informatics theory I hear and read about high-level and low-level languages all time. Yet I don't understand why this is still relevant as there aren't any (relevant) low-level languages except assembler in use today. So you get: Low-level Assembler Definitely not low-level C BASIC FORTRAN COBOL ... High-level C++ Ruby Python PHP ... And if assembler is low-level, how could you put for example C into the same list. I mean: C is extremely high-level compared to assembler. Same even for COBOL, Fortran, etc. So why does everybody keep mentioning high and low-level languages if assembler is really the only low-level language.

  • GPGPU programming with OpenGL ES 2.0

    - by Albus Dumbledore
    I am trying to do some image processing on the GPU, e.g. median, blur, brightness, etc. The general idea is to do something like this framework from GPU Gems 1. I am able to write the GLSL fragment shader for processing the pixels as I've been trying out different things in an effect designer app. I am not sure however how I should do the other part of the task. That is, I'd like to be working on the image in image coords and then outputting the result to a texture. I am aware of the gl_FragCoords variable. As far as I understand it it goes like that: I need to set up a view (an orthographic one maybe?) and a quad in such a way so that the pixel shader would be applied once to each pixel in the image and so that it would be rendering to a texture or something. But how can I achieve that considering there's depth that may make things somewhat awkward to me... I'd be very grateful if anyone could help me with this rather simple task as I am really frustrated with myself. UPDATE It seems I'll have to use an FBO, getting one like this: glBindFramebuffer(...)

  • netlogo programming question - catalyst implementation part 2

    - by user286190
    hi the catalyst speeds up the reaction but remains unchanged after the reaction has taken place i tried the following code breed [catalysts catalyst] breed [chemical-x chemical-x] ;then the forward reaction is sped up by the existence of catalysts to react-forward let num-catalysts count catalysts ;speed up by num-catalysts ;... end and it works fine but I want to make it so that the catalyst can be switched on and off with the 'switch' button ..so one can see the effects with and without the catalyst..i tried putting a switch in but catalyst has already been defined Also i want to make the catalyst visible so one can see it in the actual implementation (in the world) like making it a turtle is there are another way to implement this apart from using breeds i tried making the catalyst a turtle but it doesnt work ; Make catalyst visible in implementation clear-all crt catalysts 100 ask catalysts [ set color white ] show [breed] of one-of catalysts ; prints catalysts any help will be greatly appreciated thank you

  • SSIS - Wizard vs manual vs programming

    - by alchemical
    I'd like to move 26 tables from one DB to another. I see I can do this in the SSIS Import and Export Wizard. I believe the other approach would be to select tools from the toolbar in Data Flow and then configure them all. When is it better to use the wizard and when is it best to create the package manually (with the visual tools) or programmatically? One thing I noticed with the Wizard is that it lets me select multiple tables at once, but I could not find a way to get back to that screen once the package is created, so that I could edit the various tables all in one place.

  • Linux Kernel programming: trying to get vm_area_struct->vm_start crashes kernel

    - by confusedKid
    Hi, this is for an assignment at school, where I need to determine the size of the processes on the system using a system call. My code is as follows: ... struct task_struct *p; struct vm_area_struct *v; struct mm_struct *m; read_lock(&tasklist_lock); for_each_process(p) { printk("%ld\n", p->pid); m = p->mm; v = m->mmap; long start = v->vm_start; printk("vm_start is %ld\n", start); } read_unlock(&tasklist_lock); ... When I run a user level program that calls this system call, the output that I get is: 1 vm_start is 134512640 2 EIP: 0073:[<0806e352] CPU: 0 Not tainted ESP: 007b:0f7ecf04 EFLAGS: 00010246 Not tainted EAX: 00000000 EBX: 0fc587c0 ECX: 081fbb58 EDX: 00000000 ESI: bf88efe0 EDI: 0f482284 EBP: 0f7ecf10 DS: 007b ES: 007b 081f9bc0: [<08069ae8] show_regs+0xb4/0xb9 081f9bec: [<080587ac] segv+0x225/0x23d 081f9c8c: [<08058582] segv_handler+0x4f/0x54 081f9cac: [<08067453] sig_handler_common_skas+0xb7/0xd4 081f9cd4: [<08064748] sig_handler+0x34/0x44 081f9cec: [<080648b5] handle_signal+0x4c/0x7a 081f9d0c: [<08066227] hard_handler+0xf/0x14 081f9d1c: [<00776420] 0x776420 Kernel panic - not syncing: Kernel mode fault at addr 0x0, ip 0x806e352 EIP: 0073:[<400ea0f2] CPU: 0 Not tainted ESP: 007b:bf88ef9c EFLAGS: 00000246 Not tainted EAX: ffffffda EBX: 00000000 ECX: bf88efc8 EDX: 080483c8 ESI: 00000000 EDI: bf88efe0 EBP: bf88f038 DS: 007b ES: 007b 081f9b28: [<08069ae8] show_regs+0xb4/0xb9 081f9b54: [<08058a1a] panic_exit+0x25/0x3f 081f9b68: [<08084f54] notifier_call_chain+0x21/0x46 081f9b88: [<08084fef] __atomic_notifier_call_chain+0x17/0x19 081f9ba4: [<08085006] atomic_notifier_call_chain+0x15/0x17 081f9bc0: [<0807039a] panic+0x52/0xd8 081f9be0: [<080587ba] segv+0x233/0x23d 081f9c8c: [<08058582] segv_handler+0x4f/0x54 081f9cac: [<08067453] sig_handler_common_skas+0xb7/0xd4 081f9cd4: [<08064748] sig_handler+0x34/0x44 081f9cec: [<080648b5] handle_signal+0x4c/0x7a 081f9d0c: [<08066227] hard_handler+0xf/0x14 081f9d1c: [<00776420] 0x776420 The first process (pid = 1) gave me the vm_start without any problems, but when I try to access the second process, the kernel crashes. Can anyone tell me what's wrong, and maybe how to fix it as well? Thanks a lot! (sorry for the bad formatting....) edit: This is done in a Fedora 2.6 core in an uml environment.
