  • Simple form validation

    - by ElendilTheTall
    Hi, I have a site with a simple contact form using ASP for customers to e-mail quote requests. However, I'm getting quite a few messages through with no contact information; I think people assume that their e-mail address is coming through automatically. I'd like a simple way to make the e-mail and/or telephone number fields required, preferably so that the fields are highlighted as such if they're submitted without anything in them. I've Googled for this but they seem either too simple, diverting people to a separate page and requiring a 'back click', or incredibly complicated with massive reams of code. Any suggestions?

  • Sharing SCTP connection with multiple threads

    - by poly
    I have an application that needs to run in SCTP environment, I have a question in sharing the connection among multiple threads for packet receiving only, I've tried with the sctp_sendmsg and it worked without even locking the threads (is that been taking care of by the OS, in other words, is it thread safe to do that). I've tested many cases with the send and I can't see them out of sync. Anyway, back to the receiving, is it possible to create multiple threads and send each thread the sctp descriptor to start receiving messages? Do I need a lock here or is it ok without lock? I'm using C in linux.

  • What is cloudfront.net and what does it do?

    - by JK01
    I frequently have messages like this in my websites error log: "Script error.". URL: https://e3m4drct5m1ays.cloudfront.net/items/loaders /loader_21.js?pid=21&systemid=13504281c5a501837196c23300f84e66&aoi=1327214632& zoneid=16620&cid=HK&rid=Hong%20Kong%20(general)&ccid=Kowloon&dma=0. Line number: 0 Error name: Stack: Now I don't actually know what cloudfront is or what it does. And I do not refer to this script in my site. So why would I be getting js error logged as if it was a script being run on my own site? This is using elmah logging.

  • Online Poker Game Programming

    - by Eyal
    I am trying to write a massive online multiplayer client for a poker site, where one user can be on a Flash client and the other on say an iOS client (iPhone / iPad), and would like to know how can interaction between two users be visible on both clients. What would be better to use? Should I use MSMQ? AJAX? Something other? I need the messaging layer (client interaction messages) to scale up to 100K+ online users to begin with. In other words; What scalable technology can I use to make game interactions between online users visible to all game participants?

  • No keyring secrets found for [ssid] /802-11-wireless-security, ubuntu 12.04

    - by acimer
    I'm on Ubuntu 12.04 x64bit, installed it couple of days ago. The issue i'm having is this: on startup it connects to my wireless without a problem, but after a while I am disconnected and prompted to enter the key for the wireless network (which is entered - saved) so i just click 'ok', but wireless doesn't connect again. Reseting network manager doesn't help either. Only restart, after which, ubuntu connects to the said wireless without a problem. Terminal outputs this error message: ** Message: No keyring secrets found for cimermanovic /802-11-wireless-security; asking user. cimermanovic is the ssid name. also, here are some error messages that network manager is giving: (nm-applet:31926): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width 0' failed (nm-applet:31693): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width 0' failed (nm-applet:30184): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width 0' failed What should i do to fix this?

  • design for a parser to handle very large files

    - by user619818
    I have written a program which records protocol messages between an application and a hardware device which matches each application request with each hardware response. This is so that I can later remove the hardware, connect a 'replay' application to the main application and wait for an application request and reply with a matched copy of the requisite hardware reply message. My replay application saves the matched request/response in a list (using C++ std::list). This works fine on a small interaction session. My problem now is that I need to be able to use the replay over a long long session. With my current implementation, the replay program eventually uses up all available memory on my computer and crashes. So I need some sort of lookahead - and not parse the whole session in one go. Can anyone make any suggestions on how to get started?

  • nagios3 Error: Could not read object configuration data!

    - by user1493730
    I have a brand new install of nagios3 on ubuntu 12.04. After I log in to the web interface and click any link I get the error: Error: Could not read object configuration data! Here are some things you should check in order to resolve this error: Verify configuration options using the -v command-line option to check for errors. Check the Nagios log file for messages relating to startup or status data errors. I ran it with the -v option and it reported no errors: Total Warnings: 0 Total Errors: 0 Things look okay - No serious problems were detected during the pre-flight check The nagios log and apache error log and debug log all have nothing regarding this. Does anyone know how to turn on logging that will give me some kind of useful error? Or if anyone knows how to fix this specific problem without additional logging, I guess that's okay too. Thanks!

  • If all variables are a subset of the superkey, is the database design 5NF? [migrated]

    - by Lukazoid
    I have a table called LogMessages, which has the following columns: Level A numeric value which represents Trace, Debug, Info, Warning, Error or Fatal Time A UTC time Message Foreign key to a Messages table Source Foreign key to a Sources table User Foreign key to a Users table From what I can see, all of these columns are a part of the super key; if any single value differs to an existing row, a new row can be created. My question is, does this design comply to fifth normal form? I am unsure as some groups of data will be repeating, however I don't believe this violates 5NF? (correct me if I'm wrong)

  • Kernel Panic Fatal Machine Check

    - by 0x4a6f4672
    I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-(

  • Tons of problems a new user is encountering

    - by Barney
    I've borrowed this laptop from a friend. I wanted to install AdBlock to boost performance. First weird thing was that even though I was on Chrome, Chrome suggested me installing him? So I tried to install ,than it gave me some message about broken dependencies. I Googled and tried to run those commands you guys were suggesting, but than it popped up error messages about everything again. Than I found out that some package called linux image generic is broken, than I tried to find an answer to that, but on the topic it was ” ndk.bhj\spo;ujvsdljvaEOYUFgidgAPIF;hsgvk in other words, I didn't understand anything about it, than there's this thing: E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? Seriously, when I'm trying to fix an error, there is another one. I'm on something called GNOME. Sooo, where do I start?

  • Raspberry Pi + Azure + Mobile App

    - by Richard Jones
    Ongoing project idea. So this is of long running personal interest to build a Mobile App that shows you a push notification/pop up alert, when anyone calls your house phone. So I've taken delivery of a Raspberry Pi. I've ordered a new Crucible Technology Caller ID Box. (arriving soon). I have been writing/learning Python to implement the Listener software. This will in turn push xml messages up to Azure for final delivery via push notifications to an App. iOS app already written to receive the notifications/allow address book additions made up from phone numbers from incoming calls. So this is fusion, R-Pi, Azure, Hardware and iOS. Details to follow as this plan unfolds.

  • Can you find the problem in my boot-info

    - by erich
    I'm trying to install Ubuntu 12.04 for two days now. Thats something pretty strange because normally thats done in about half an hour. It doesn't boot whatever I try. I got several different types of not-booting until now. All without significant error messages. Now that I'm running out of ideas I thought maybe one of you is able to find my mistake. The boot info is at http://paste.ubuntu.com/1265205/ If you need any other information I'd be happy to provide it.

  • Evolution and thunderbird sharing same mail data?

    - by balki
    Hi, I have been using Evolution for a quite long and it has downloaded around 1.6GBs of mails from gmail. I want to try thunderbird but I dont want to re download everything again. Is that possible to have both clients sharing same data? I'll make sure I don't use both at the same time if that matters. I'll move to thunderbird fully if I'm happy with it. Problems I face with evolution is that I have to have the GUI running always if I want to get instant alerts and send mail immediately. Also it loads the messages slow and even after I move to the next mail, it slowly downloads all the linked images before moving on.

  • Empathy auto accept group chat invite

    - by Sivaji
    I'm using empathy 2.34.0 as chat client for account hosted on Google app (server talk.google.com). I'm happy with the features that empathy provides and integration with Google chat, however for group chat when the request is received I need to click on "join" button showed in popup to get started. This makes sense but I would to know if there is any way to automatically join the chat room without clicking the "join" button as I use it only with trusted uses. Besides the messages shared after the invite request and before my entry to chat room is not accessible to me. I looked around the empathy settings but couldn't find anything useful, wondering if I can get some help from here. Thanks.

  • Can't start x session after updating packages

    - by chaos
    I have recently upgraded to 12.04 and all seems ok except adobe flash plugin doesn't work. But one several days ago when I installed several update packages and rebooted the x session was unable to start and it automatically switches to console 1 for commandline login. What's frustrating is there's essentially no error messages when I click alt+F7 to see what's going on with the x session. There are a bunch of [ok]'s and the last line seems to be something like 'starting x font server' and it just hang there. The closest thing to an error is something like 'stopping system V compatability (*words I can't remember*) ... [ok]'. This is nearly the most frustrating experience I've ever had with linux in the past 10 years. Can anyone help me?

  • We Heart Discussion Forums (and Know You Do Too)

    - by oracletechnet
    It's not generally known, but Oracle (via Oracle Technology Network) hosts one of the largest discussion forums instances (forums.oracle.com) on the planet (founded in 2001), containing nearly 10 million messages from 1 million registered users. That's a whole lot of conversations! And we really, really value those conversations - they span almost every conceivable technical subject across hundreds of products and technologies. More often not - and this is by design - those discussions are stewarded by community volunteers, many of whom are Oracle ACEs (who in fact earned their ACE stripes that way). And so, I am very happy to tell you that we have just initiated a project with our platform partner, Jive Software, to upgrade that platform to the most current, modern version available. The end result should be a vastly improved user experience for everyone involved, in all dimensions. There are many, many details to work on in coming weeks, but we'll keep you posted - and, when needed, come back to you for advice and suggestions. For now, we just wanted to share the good news!

  • Passing data between engine layers

    - by spaceOwl
    I am building a software system (game engine with networking support ) that is made up of (roughly) these layers: Game Layer Messaging Layer Networking Layer Game related data is passed to the messaging layer (this could be anything that is game specific), where they are to be converted to network specific messages (which are then serialized to byte arrays). I'm looking for a way to be able to convert "game" data into "network" data, such that no strong coupling between these layers will exist. As it looks now, the Messaging layer sits between both layers (game and network) and "knows" both of them (it contains Converter objects that know how to translate between data objects of both layers back and forth). I am not sure this is the best solution. Is there a good design for passing objects between layers? I'd like to learn more about the different options.

  • No splash screen on hibernate

    - by Marky
    Hibernate is working fine. A bit slow when resuming from a hibernate but I can bear with it just so that I have all open applications on the desktop as I left it. Then again the "slowness" might be because of the 4GB RAM, although I'm assuming only what is used gets swapped and not the entire memory. Going back, my question is has anyone been able to make Ubuntu show a splash screen or some kind of indicator/progress bar to show while hibernating or while resuming? I remember with SuSE on my HP Compaq Presario notebook it had messages appear during and after. Better than nothing, I guess. Thanks in advance! :D

  • how to install/compile CORSIKA/FLUKA for Ubuntu x32 12.04?

    - by Pantea Davoudifar
    I want to use some programs (CORSIKA/FLUKA) which are essentially designed for 32 bit systems. so I installed Ubuntu 12.04 32 bit on my system (Intel® Core™ i7-2700K CPU @ 3.50GHz × 8). Before this I had installed Ubuntu 9.10 (32-bit) on an older system and installed g77 from hardy repositories, compiled those programs without any problem. But this time when changing the repositories, g77 could not be installed even i removed all the things that i thought make this installation impossible, for example I need gcc-3.4 and removed all newer versions and tried to install them from hardy repositories. but the problem is that, whenever I have g77, corsika does not compile, and whenever I remove it, fluka does not compile, and also i received a error messages like this: crt1.o not found in /usr/bin/lb. In fact these .o files does not exist on my system user/bin/lb I have no directory lb there? I do not know how to link it? Or do i need to reinstall everything?

  • Help file formats - MSHA files v CHM files

    - by TATWORTH
    Recently I was tasked with producing a help file from a C#/WPF/Crystal Reports application using Sandcastle. I have previously blogged about the problems in doing that and the change that is going into the next version of Sandcastle that allows the vagaries of Crystal (this missing BusinessObjects.Licensing.KeycodeDecoder) to be handled. At http://social.msdn.microsoft.com/Forums/en-US/devdocs/thread/0b110502-f5bb-4c56-96a5-4347a2a7a68a/, I describe how I tried each of the formats. Two of the formats could not be built and the error messages were not exactly helpful as to the cause. These two formats turned out to be obsolete. The MSHA format worked but was not suitable for a standalone application, so that left me with the older CHM format. I therefore asked on that thread "will the HTML Help 1 (CHM) format continue to be supported for the foreseeable future?".Rob Chandler, MVP in help systems, gave a very helpful answer, to the effect that there is not yet a replacement for the CHM format.
