  • Is there a lightweight MTA for Ubuntu 9.10 Desktop?

    - by Joe Casadonte
    I'm writing a Perl script to run as a cron job, and I want to email results & errors to a local account on the laptop. I'd like something that can talk SMTP (do any MTAs not adhere to SMTP?). I use Thunderbird 3, so I'll also need a POP/IMAP server (unless T-Bird can read straight from an mbox file; I'll have to check into that). No need for spam controls as I'll lock it down real tight, only accepting mail originating from the laptop itself. Thanks!

  • Hash 32bit int to 16bit int?

    - by dkamins
    What are some simple ways to hash a 32-bit integer (e.g. IP address, e.g. Unix time_t, etc.) down to a 16-bit integer? E.g. hash_32b_to_16b(0x12345678) might return 0xABCD. Let's start with this as a horrible but functional example solution: function hash_32b_to_16b(val32b) { return val32b % 0xffff; } Question is specifically about JavaScript, but feel free to add any language-neutral solutions, preferably without using library functions. Simple = good. Wacky+obfuscated = amusing.

    - by maddy
    HI All, I have a piece of ada code shown below which is a simple switch case statements.Is there any better way to convert this into C. for I in 1..100 loop case I is when 100 => Dollars := Dollars + 1; when 25|50|75 => Quarters := Quarters + 1; when 10|20|30|40|60|70|80|90 => Dimes := Dimes + 1; when 5|15|35|45|55|65|85|95 => Nickles := Nickles + 1; when others => Pennies := Pennies + 1; end case; end loop; Now by adding the switch and the case for each values in the case,i can do that conversion,But it seems tyo make the code too big.Is there anywa other simple and compact way.Please get back to me if the question is not clear? Regards maddy

    - by wcpro
    I'm trying to post to a form using jQuery and read the results of the posted page. I have created a super simple example. $('#submit').click( function () { $.get('post.htm', { demo : "true" }, function (data) { alert('data load: ' + data); },) }); the html page for post.html is just a simple html form <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> this is a post </body> </html>

  • Is there a service for monitoring secured WCF endpoints in the same way that HTTP monitoring service

    - by Ryan ONeill
    Hi all, A service I have in WCF occasionally goes down due a problem with a COM component. While I am troubleshooting I would like to setup another host to make regular calls to this service to monitor availability. It is slightly more complicated that a simple HTTP call though as the service is secured by SSL and WCF authentication (username / password). I'd also like to be able to parse successful calls to see if they return warning / fail states from my code. Would you recommend any monitoring providers for this or is it beyond the simple monitoring they normally provide? Regards Ryan

  • Restaurant review site in SharePoint

    - by Sisiutl
    I'm totally new to SharePoint but my company has adopted it for internal use. As a learning exercise I thought it would be fun to create a local restaurant review site. Can anyone point me to an example or tutorial to get me started? What I have in mind is a simple site where users can enter the restaurant name, cuisine style, address, a simple 5 point rating and price scale, and a short review. Other users could search for restaurants by cuisine and add their own reviews. We have SharePoint 2007 and MOSS. Thanks

  • Direct DB to Web Server connection

    - by Joel Coel
    I have a database server sitting right underneath a virtual machine host server in the rack, and this vm host is primarily responsible for servers hosting a couple different web sites and app servers that all talk to databases on the other server. Right now both servers are connected to the same switch, and I'm pretty happy with the pathing. However, both servers also have an unused network port. I wondering about the potential benefits of using a short crossover or normal+auto mdix network cable to connect these two servers together directly. Is this a good idea, or would I be doing something that won't show much benefit and is just likely to trip up a future admin who's not looking for this? The biggest weakness I can see right now is that this would likely require a code change for each vm app to point to the new IP of the database server on this private little network, and if I have a problem with the virtual machine host and have to spin up it's guests elsewhere while I fix it I'll have to change this back before things will work.

  • homegroup administrator user no longer exists

    - by Beninja
    I had a PC with windows 7 that was the homegroup administrator for my network. I recently upgraded to windows 8 I went to homegroup in control panel and saw that the original homegroup was never removed. It says to talk to the administrator on and obtain the password to join the homegroup. I need to create a new homegroup but I cant unless I somehow remove the old one. And I cant do that because the user that had rights to the old one no longer exists. Please help!! Ben

  • Running log operation in Http Modules?

    - by Niranjan
    Hi, I have a simple requirement in which I want to execute a long running application program on server (e.g. DTSX) I want to make an HTTP module for this, But I have a question whether the DTSX will run even if the user closes the page and browser. In my case user hits the handler with a query string but what if the user closes the browser immediately? How is the behavior different from simple linear page processing? I want my DTSX package to finish once its started no matter how much time it takes and also dont want to halt the user that is why I am using http modules in place of linear asp page processing. Reagrds, Niranjan

  • Can I set up a COM Port that Connects via TCP/IP?

    - by Kristopher Johnson
    I have an RS232 device connected to a Digi PortServer on my network. I can telnet to the Digi's IP and port number to communicate with that RS232 device. I have a Windows application that knows how to talk to the device, but it wants to connect directly to an RS232 port. So, my question: Is there some way to set up a COM port so that when this application connects to it, it goes through the network to the Digi to communicate with the device? I have run across the utility TCP-Com, which seems like it might be a solution. Is this the best option?

  • Rationale behind Python's preferred for syntax

    - by susmits
    What is the rationale behind the advocated use of the for i in xrange(...)-style looping constructs in Python? For simple integer looping, the difference in overheads is substantial. I conducted a simple test using two pieces of code: File idiomatic.py: #!/usr/bin/env python M = 10000 N = 10000 if __name__ == "__main__": x, y = 0, 0 for x in xrange(N): for y in xrange(M): pass File cstyle.py: #!/usr/bin/env python M = 10000 N = 10000 if __name__ == "__main__": x, y = 0, 0 while x < N: while y < M: y += 1 x += 1 Profiling results were as follows: bash-3.1$ time python cstyle.py real 0m0.109s user 0m0.015s sys 0m0.000s bash-3.1$ time python idiomatic.py real 0m4.492s user 0m0.000s sys 0m0.031s I can understand why the Pythonic version is slower -- I imagine it has a lot to do with calling xrange N times, perhaps this could be eliminated if there was a way to rewind a generator. However, with this deal of difference in execution time, why would one prefer to use the Pythonic version?

  • ASP.NET Web Service - Passing a base object with list/collection?

    - by schooner
    We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission. The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n. Jan 1 2009, ABC May 1 2010, 123 Jun 30 2010, XXXXX What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX

  • Animating a font size change in a UITableView

    - by nickthedude
    Hey Simple little app for educational purposes, its a simple uitableview and I want users to be able to use a uislider to adjust the font size as needed. The code I have now works to change the font but only when the view is updated, ie when i pull up or down the table view to reveal other cells. I'd like the font change to be reflected immediately as a user moves the uislider if possible, here's the code that I have working half way: -(UITableViewCell *) tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.text = [listData objectAtIndex:row]; UIImage *image = [UIImage imageNamed:@"star.png"]; cell.font = [UIFont systemFontOfSize:[fontSlider value]]; cell.image = image; return cell; }

  • software to emulate a blackboard over internet

    - by Abhijith Madhav
    I need to tutor my brother on a particular topic. We live in different geographical areas. We use g-talk to do the same. We do not have web-cam's to enable video chat. The tutoring will involve a lot of off-the-cuff illustrations. I am hence searching for a suitable software which will emulate a blackboard over an internet connection. I need the software to enable sharing of a common canvas on which I can draw, write and point to. Say a Microsoft paint canvas on internet. Could you point out a suitable software? Google is not of being help at the moment as I suspect that I am not specifying my search criteria properly.

  • Lotus Notes doesn't send customised button

    - by damo_inc
    Hi All, I created a customised button with some simple actions attached to it in Lotus Notes 6.5. It's just a simple voting button, which I emailed to a group of nearly 200 people. While sending I got a pop up telling me that the button can't be send. After about 10 seconds I got a first reply asking 'where's the button'. Then an avalanche of very clever emails followed, such as: 'no button', 'where's the button', etc. Before I spammed everyon I had tried the email on my work mate and the button went through fine! Any ideas? I suspect some security policy.... I really need to send this mail and get the survey results, so I don't want to fail again. Any suggestions appreciated. Many Thanks, Damo

  • Log4cxx sample program and steps to compile

    - by Jake
    Hi guys Hoping someone can help out.. I've been scouring the net for a simple how-to to get a good log4cxx program working, with steps on setting up the libraries, dependants, directives, library paths etc etc.. as of yet i've found a lot of valuable but disjointed information.. trying to pull it all together has been a bit of a nightmare, so i'm reaching out and wondering if any kind soul knows of, or could put together a simple how-to, to get a standard win32 console app running with either static or dynamically linked release mode log4cxx.. I have win32 binary releases of the libraries, and thanks to a very cool dude from "Must a blog have a name" I have a win32 project which can build log4cxx.. i just cant bloody use it :) It would be really helpful to me, and probably to others, to be able to refer to something like this and not 20 different pages, with different lists of libraries needed to download and install.. :) Here's hoping Thanks guys J

  • Propertygrid changes not picked up when using menu shortcut for saving

    - by Ebbe
    I am trying to implement a simple windows forms application, where the user can edit instances of a simple Person class. The application makes use of the standard propertygrid, assigning instances of the Person class to the SelectedObject property of the propertygrid. When the user clicks the menu item Save, the application gets the selected item from the propertygrid and saves it. This works fine. However, if a shortcut such as ctrl+S, assigned to the menu item, is used for saving the SelectedObject of the propertygrid, then the changes are not picked up. It appears to be related to the fact that the properties of the Person object are not updated unless the field in the propertygrid looses focus, and the ctrl+S shortcut doesn’t take away focus from fields in the propertygrid. Other developers, such as Mark Gilbert, have solved this issue by forcing away focus from the propertygrid, but this seems to be a bit of a hack, especially since it would be nice to keep the focus at the field. The Visual Studio developers apparently got it right, but I haven’t figured out how.

  • mysql: encrypting and decrypting data

    - by cbrulak
    Does mysql provide a mechanism for storing and retrieving encrypted data? I don't mean passwords, I mean real strings. I'd like to encrypt a string, store in mysql and then retrieve the decrypted string at a later date. So, I know there is the AES_Encrypt and decrypt functions. But they ask for a key. (which is fine) but I wondering if you call those functions and use your user password as the key. Or something else that is super-simple. Also, is there a simple wrapper for the AES_Encrypt & decrypt functions in Rails? Or do you need to build the query manually?

  • How to: WCF XML-RPC client?

    - by mr.b
    I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side, what I would like to accomplish is to create a simplest possible client (in C# preferably) using WCF. Let's say that Contract for service exposed via XML-RPC is as follows: [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. Aaand, what's next? :) P.S. I have tried googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big/numerous) classes, which implement appropriate IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

  • How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

    - by Marco Mariani
    I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks

  • Read entire file in Scala?

    - by Brendan OConnor
    What's a simple and canonical way to read an entire file into memory in Scala? (Ideally, with control over character encoding.) The best I can come up with is: scala.io.Source.fromPath("file.txt").getLines.reduceLeft(_+_) or am I supposed to use one of Java's god-awful idioms, the best of which (without using an external library) seems to be: import java.util.Scanner import java.io.File new Scanner(new File("file.txt")).useDelimiter("\\Z").next() From reading mailing list discussions, it's not clear to me that scala.io.Source is even supposed to be the canonical I/O library. I don't understand what its intended purpose is, exactly. ... I'd like something dead-simple and easy to remember. For example, in these languages it's very hard to forget the idiom ... Ruby open("file.txt").read Ruby File.read("file.txt") Python open("file.txt").read()

  • Advice needed: What tech expertise do I need to accomplish my goal?

    - by quaternion
    I have a business plan & money to hire a developer - the essentials involve simple online games for children (played via traditional computer over the internet) such that their scores are uploaded to a database that can be viewed via a nice portal. What I don't know is: what technologies I would want my developer to know (the only somewhat unusual requirement I have is that the games have relatively accurate timing of keypresses/mouse presses) how much I should expect to pay (in general, what is the appropriate range) how many hours a program of the complexity of a simple tower defense -type game should take to develop (to be clear, the idea is not to implement TD, but rather other games of similar complexity) whether I should go with capable acquaintances, some online kind of online web-dev bidding site, or just try to find a capable undergraduate at the local university who I can wow with his/her first big paycheck, how I should communicate the software's specifications to my hired developer... Is there a standard I should be using? whether I should hire a webdev consultant for a few hours to help me answer these questions, instead of asking stackoverflow Thanks for any advice!
